- Hinges include, but are not limited to, pivotable connectors, such as those used to fasten a door to frame, and living hinges.
- Living hinges may be constructed from plastic and formed integrally between two members. A living hinge permits pivotable movement of one member in relation to another connected member.
- the cover 34 is openable for insertion of paper products 12 into the interior area 32 of the housing 14 when the supply of paper products is depleted and/or runs low.
- the fastener 36 that holds the cover 34 closed may, for example, include interlocking tabs 48 . At least one of the interlocking tabs 48 is movable when desired to reopen the cover 34 by pressing the button 38 to release the connection of the tabs 48 . Any other type of fastener 36 known to those skilled in the art for reopenably securing the cover 34 may be used.
- the cover 34 further includes a group of control ribs 52 that extend into the interior area 32 to contact paper products when the cover is in the closed position.
- the control ribs 52 space, slow, align, and/or support paper products as the same are moved toward the cover 34 and through the dispensing opening 40 . Size, shape, and spacing of the control ribs can be used to control dispensing of the paper products.
- the control ribs 52 may have different dimensions to properly support and guide the paper products into the dispensing opening 40 . For example, a tall rib member 56 extends into the interior area 32 by a greater amount than a short rib member 58 .
- the tall rib members 56 and short rib members 58 are illustrated to show an exemplary dispensing configuration. Additionally, a side surface 60 of the tall rib member 56 closest to the interior surface 30 may be configured so there is little or no offset from the interior surface. A side surface 62 of the short rib member 58 may be offset from the interior surface 30 by a greater amount.
- the tall rib member 56 may have a height ranging from about 1 to about 2 inches at the location where it intersects with the first side wall 22 and an offset or height ranging from about 0.1 to about 0.5 inch adjacent the dispensing opening 40 .
- the short rib member 58 may have a height ranging from about 0.5 to about 1.5 inch at the location where it intersects with the third side wall 26 and an offset or height ranging from 0 to about 0.25 inch adjacent the dispensing opening 40 .
- the rib members may have various widths or thicknesses and the width of a rib member may vary along any dimension or dimensions. Desirably, the portion of the rib member contacting the paper product will be relatively thin and smooth to minimize friction.
- the use of rib members is further described in U.S. Pat. No. 6,241,118 to Tramontina and PCT Publication WO 99/30601, the entire contents of which are incorporated herein by reference.
- the container 10 further includes a means for elevating paper products 50 toward the dispensing opening 40 in the cover 34 .
- a means for elevating paper products 50 may comprise any structure that allows paper products to be urged toward and dispensed from the dispensing opening 40 in the cover 34 .
- the means for elevating paper products 50 is discussed more fully below in conjunction with FIG. 5 .
- the dispensing opening 40 may have many shapes within the scope of the present invention, as long as the opening provides easy access for a user.
- the dispensing opening may also be configured to provide metered delivery of individual paper products.
- the paper products 12 are interfolded, tabbed, or tab interfolded to provide metered feeding of individual paper products one at a time.
- Folding devices such as boards or plates, have long been used to longitudinally fold webs and other sheet-like materials in order to form a stack of folded sheets. The sheets are, generally speaking, drawn over the folding device wherein the shape and configuration of the device causes the sheet to twist and bend thereby producing the desired fold.
- Folding devices have heretofore been provided in a variety of shapes and configurations in order to achieve the desired fold lines and folding patterns. Folding devices have been used to form a number of different folds including, for example, half-folds, quarter folds, c-folds, v-folds, j-folds, w-folds, z-folds, and so forth.
- folding boards have also been used in series to achieve inter-folded or inter-leafed sheets, that is to say sheets folded such that they partially envelope portions of another sheet.
- Inter-leafed sheets are commonly employed in stacks as a mechanism to facilitate removal of the individual sheets from a dispenser. Withdrawal of a first sheet through a dispenser opening pulls the enveloped portion of a second sheet through the dispenser opening such that it extends out of the dispenser opening and is exposed. Having a portion of the subsequent sheet extending out of the dispenser opening greatly facilitates removal of the same from the dispenser by the user.
- the housing 14 may include one or more tabs 54 attached to the interior surface 30 near the opening in the housing 14 through which paper products are loaded.
- the tabs 54 are dimensioned such that they inhibit a cartridge containing paper products from being loaded in an improper orientation.
- the tabs 54 align with slots in a cartridge such that the slots will catch on the tabs 54 if the cartridge is not oriented properly prior to loading the cartridge into the housing 14 .
- the cartridge is aligned properly, there are no slots to catch on the tabs 54 and the cartridge will slide into the housing 14 unimpeded.
- the housing 14 may be made from numerous materials and by numerous methods known to those skilled in the art.
- the housing 14 may be made of plastic such as polyethylene, nylon, and so forth. However, other suitable materials, such as other plastics or metals, may be provided for any or all of the parts of the housing 14 .
- the housing 14 may be made of an injection-molded plastic.
- the protrusions 42 , control ribs 52 , and tabs 54 are desirably formed integral with the housing 14 .
- the protrusions 42 , control ribs 52 , and tabs 54 may be formed separately from the housing 14 and attached later.
- the protrusions 42 , control ribs 52 , and tabs 54 may be made of different material from the housing 14 if desired.
- the protrusions 42 , control ribs 52 , and tabs 54 may be made of a more resilient material than the materials described above, such as an elastomer or rubber.
- a cartridge may be provided for holding paper products to be dispensed to a user.
- a cartridge 70 having outside walls 72 is provided for insertion into the interior area 32 of the housing 14 for containing paper products 12 to be dispensed.
- the cartridge has a bottom end 74 that is adapted to receive the means for elevating paper products 50 and a top end 76 adapted to dispense paper products 12 .
- the cartridge 70 is sized to fit within the interior area 32 of the housing 14 .
- the cartridge 70 is sized to be only slightly smaller than the housing 14 to maximize the number of paper products 12 contained within the cartridge.
- the cartridge 70 can hold and dispense significant numbers of individual sheets. Desirably, the cartridge 70 is sized to hold and dispense at least about 250 sheets. By way of example, the cartridge 70 can contain between about 400 and about 1000 sheets. In certain embodiments, the cartridge 70 can contain and dispense between about 700 and about 900 sheets.
- the cartridge includes a plurality of removable portions, the removal of which creates openings through the cartridge.
- One such detachable portion may be disposed at the bottom end 74 of the cartridge 70 , to provide an internal platform 82 .
- a separate internal platform may be provided, which may either be attached or detached from the means for elevating paper products 50 .
- Detachment of the portion of the bottom end 74 of the cartridge 70 namely, the internal platform 82 , allows this portion of the cartridge 70 to receive the means for elevating paper products 50 when the cartridge 70 is loaded into the housing 14 .
- the removable portion may be flaps which can be folded back to create an opening.
- the cartridge 70 may include at least one removable portion that can be removed to create at least one slot 88 that will prevent misalignment of the cartridge in the housing, as shown in FIG. 4 .
- the slots 88 are desirably positioned such that when the cartridge is improperly oriented, the slots will catch on tabs 54 positioned on the interior surface of the housing.
- the slots 88 may be positioned in one of the outside walls 72 of the cartridge 70 .
- the slots 88 may be positioned in the flaps (not shown) that are opened prior to insertion of the cartridge 70 in the housing 14 . If flaps are used, and opened (not shown), the flaps fold back against the outside walls 72 of the cartridge 70 where the slots 88 would be in position to engage the tabs 54 if the cartridge is not oriented correctly.
- the cartridge 70 may include at least one of yet another removable portion at the first end wall or top end 76 of the cartridge 70 so that paper products 12 can be supported and aligned by the control ribs 52 for dispensing through the dispensing opening 40 . Removal of the removable portions creates openings 90 through which the control ribs 52 extend.
- the cartridge 70 may include at least one of another removable portion that corresponds to the protrusions 42 in the housing 14 .
- the removable portions are disposed in the outside walls 72 of the cartridge 70 so that, once the removable portions are removed, openings 92 can encompass and receive the protrusions 42 extending from the interior surface 30 of the housing 14 .
- the protrusions 42 and rib members 58 contact the paper products 12 within the cartridge 70 and act upon the paper products as described above.
- the first end wall or top end 76 of the cartridge 70 may be formed having a removable portion corresponding to the dispensing opening 40 . Removal of this removable portion creates an opening 94 through which the paper products are dispensed ( FIG. 4 ).
- the removable portions may either be removed (or simply not formed) during manufacture of the cartridge or removed just prior to installation of the cartridge in the housing. If the removable portions are to be removed as part of the manufacturing process, the cartridge should be shipped to the user wrapped, for example in a polyethylene bag, to preserve the sterility of the paper products in the cartridge. If the removable portions are to be removed as part of the installation process, the edges of the removable portions should be weakened, scored, etc. for easy removal. If a removable portion is used to provide access for the means for elevating the paper products, it should not be removed as part of the manufacturing process to ensure that the paper products remain properly loaded in the cartridge 70 until the time at which the cartridge is to be inserted in the housing 14 .
- the cartridge 70 is desirably made of heavy paper or cardboard. It will be understood, however, that the cartridge may be made of any suitable material known to those skilled in the art. Such suitable material(s) include, but are not limited to, cardboard, plastic, film, foil, and so forth.
- a plunger 100 is disposed within the interior area 32 of the housing 14 along with at least one spring 102 .
- the spring 102 urges the plunger 100 in the dispensing direction 104 .
- the plunger 100 and the spring 102 urge the paper products 12 toward the dispensing opening 40 .
- Use of a plunger and spring mechanism allows the container 10 to be used in situations where paper products are to be dispensed in a substantially vertical direction.
- the plunger 100 is shaped to provide support and lift the paper products 12 through the housing 14 without becoming stuck such that the paper products would no longer be elevated toward the dispensing opening 40 .
- the plunger can have any one of various shapes.
- the plunger 100 can take the shape of a truncated cone having a top surface 108 and a bottom surface 110 .
- the top surface 108 engages and lifts an internal platform 82 against the paper products 12 .
- the bottom surface 110 is engaged by the spring 102 .
- the diameter of the bottom surface 110 is desirably substantially equivalent to the diameter of the spring 102 .
- the bottom surface 110 of the plunger is attached to the spring 102 to prevent disengagement of the spring from the bottom surface of the plunger.
- a chain 111 also extends from and is desirably coupled to the plunger 100 . That is, one end of the chain 111 is desirably coupled to a lower surface (not shown) of the plunger 100 , and the opposite end is desirably coupled to the bottom wall 20 of the container 10 .
- the chain 111 extends inside of the spring 102 , that is, inside of the spiraling coils 122 of the spring 102 , and it assists in controlling the decompression, alignment and tensioning of the spring 102 against the plunger 100 .
- the chain 111 is desirably covered by a resilient covering 115 which includes a plurality of notches 117 .
- Each of the plurality of notches 117 may desirably be positioned at the junction of one link as it couples or links to the next link in the chain 111 , that is, each inter-linking section. Such positioning of each notch of the covering 115 permits the chain 111 to properly evenly uncoil to evenly regulate the movement, direction, alignment and tensioning of the spring 102 as the spring 102 is gradually decompressed when paper products are removed from the dispensing opening 40 , thereby permitting the plunger 100 to continue to move in the aligned dispensing position or dispensing direction 104 in the interior area 32 of the container 10 toward the dispensing opening 40 to enhance dispensing of paper products 12 .
- the plunger 100 , the spring 102 and/or the chain 111 may misalign.
- the plunger 100 , the spring 102 and/or the chain 111 may move out of alignment and against a sidewall of the container 10 or at least partially out of the opening 33 in the first side wall 22 (not shown).
- dispensing of paper products fail because the plunger 100 does not move the cartridge 70 and/or paper products 12 up to the dispensing opening 40 in the container 10 so that a user may access and remove them.
- a solid covering was placed over the chain 111 (not shown).
- the solid covering although resilient, placed too much stiffness in the chain 111 .
- the solid covering would not permit the chain 111 to uncoil and collapse within interior area 124 within the compressed spring 102 . Rather, the stiffness in the solid covering caused limited movement of the chain 111 , so that the chain 111 could not uncoil, but would fall in stiff lengths of chain which caused binding of the spring 102 . This binding again resulted in an un-even tensioning and decompression of the spring 102 , which resulted in the spring 102 and/or the plunger becoming misaligned.
- the chain 111 having a covering 115 with a plurality of notches 117 now has sufficient resiliency to coil when compressed and uncoil in a regulated basis while resisting the effects of gravity to allow the chain 111 to keep from falling inbetween coils 122 of the spring 102 , thereby preventing the chain 111 from binding up the spring 102 such that the spring 102 will not decompress, resulting in jamming and dispensing failure.
- the chain having the covering 115 with the plurality of notches allows the spring 102 to decompress so that dispensing alignment is maintained in the dispensing direction 104 .
- the chain 111 and spring are maintained in the interior area 124 .
- the chain 111 with covering 115 having notches 117 controls the movement, direction, alignment and even tensioning of the spring 102 and the plunger 100 whether in a generally vertical position or whether in a substantially non-vertical position or orientation.
- the chain may be formed from any suitable material, for example, metal, plastic, and so forth.
- the covering 115 having notches therein is desirably formed from a resilient material which permits the chain contained therein to coil and uncoil.
- resilient materials include, for example, but not by way of limitation, rubber, plastic (such as polypropylene), nylon, and so forth.
- one or more stabilizing wings 112 extend from the plunger 100 .
- the wings 112 act to distribute the force from the spring 102 to the outer edges of the internal platform 82 . As shown in FIG. 2 , the force is applied by the upper edge 114 of the wing 112 that contacts the internal platform 82 .
- the wings 112 also act to prevent the plunger 100 and spring 102 from tipping over inside the cartridge. If the plunger 100 and spring 102 begin to tip over, the outer edge 116 of the wing 112 contacts the inside surface of the cartridge 70 before the plunger can get stuck.
- the surface area of the outer edge 116 is desirably minimized to prevent the outer edge from binding against the inside surface of the cartridge 70 .
- the bevel 118 between the upper edge 114 and the outer edge 116 is configured to transition between the upper edge 114 and the outer edge 116 .
- the wings 112 may have various thicknesses and the thickness of the wing may vary along any dimension or dimensions. Desirably, the outer edge 116 of the wing 112 will be relatively thin and smooth to minimize friction against the inside surface of the cartridge 70 .
- the plunger 100 will desirably include a small post 125 extending outward from the center of the top surface 108 of the plunger 100 . It was discovered that dispensing failures occurred when the container 10 was positioned in a generally non-vertical position or orientation. That is, the effects of gravity were greater on the plunger 100 when the container 10 is positioned in a horizontal or oblique position or orientation. This is because the force of gravity permitted the plunger to shift away from its desired position against the internal platform 82 . In fact, the plunger 100 sometimes moves such that it extends at least somewhat through the opening 33 in the first side wall 22 .
- the plunger 100 then binds against a perimeter 37 of the opening 33 , and does not push the paper products and/or the cartridge toward the opening 40 in the container 10 , resulting in dispensing failure.
- the post 125 assists in maintaining the plunger in a proper dispensing alignment, particularly, but not by limitation, when the container 10 is positioned in a generally horizontal or oblique position.
- the post 125 moves into contact with a cooperative and corresponding opening 126 in the internal platform 82 .
- the opening 126 is shown as a generally square-shaped opening while the post 125 is a generally round-shaped post, it will be appreciated that the post 125 and/or the opening 126 may assume any shape(s) or configuration(s) so long as the post 125 and the opening 126 operate such that the post 125 extends into the opening 126 to assist in holding the plunger 100 in a proper alignment to prevent even and un-interrupted dispensing of paper products through the dispensing opening 40 in the container 10 . It will be appreciated that the post 125 and opening 126 act to hold the plunger 100 in a dispensing alignment in spite of the effects of gravity and/or other pressures or forces.
- the spring 102 is sized to provide sufficient force to urge and/or elevate the paper products 12 to the dispensing opening 40 .
- the spring applies substantially constant pressure against the paper products at all positions of travel. Application of substantially constant pressure helps to prevent over application of force when the plunger is toward the bottom of the dispenser and under application of force when the plunger is toward the top of the dispenser.
- the bottom of the cartridge is opened prior to insertion of the cartridge into the housing to enable the contents of the cartridge to be engaged by the means for elevating the paper products 50
- the second end wall or bottom end 74 of the cartridge 70 may contain the internal platform 82 .
- the internal platform 82 is prevented from falling out of the cartridge 70 because the internal platform 82 provides a portion of the second end wall or bottom end 74 of the cartridge 70 .
- the internal platform is delineated by lines of weakness 75 or perforations which permit it to be separated from the rest of the bottom end 74 .
- the largest dimensions of the platform 82 are desirably slightly smaller than the internal dimensions of the cartridge 70 so that the platform can move through the cartridge as paper products are dispensed without binding against the internal surface of the cartridge. Desirably, the largest dimensions of the platform may be substantially equal to or may be slightly larger than the paper products to provide uniform dispensing of the paper products.

- the top 404 of the at least one tower 130 contacts the portion or the bottom end 74 which provides the internal platform 82 to cause the internal platform 82 to be separated without ripping or tearing of bottom end 74 .
- the cross-sectional area of the top 132 of the at least one tower 130 should be selected so that the top will separate the internal platform 82 from the remaining bottom end 74 rather than puncturing the internal platform 82 .
- the cross-sectional area of the top 132 may be greater than 0.5 cm 2 , and desirably may be greater than 1 cm 2 .
- towers 130 may be used as are necessary to provide a clean separation along the lines of weakness 75 of the internal platform 82 from the bottom end 74 .

- the bottom end 74 of the cartridge 70 having the internal platform 82 capable of receiving the means for elevating paper products 50 can be positioned against the plunger 100 attached to the spring 102 within the container 10 .
- the post 125 on the top surface 108 of the plunger 100 is desirably positioned into the opening 126 in the bottom end 74 of the cartridge 70 .
- the cartridge 70 is then pushed down against the plunger 100 , depressing the plunger 100 against the spring 102 until the cartridge is nearly seated in the housing 14 of the container 10 .
- the internal platform 82 is separated via the lines of weakness 75 from the bottom end 74 of the cartridge 70 by either the fully compressed plunger 100 or, if present, the at least one tower 130 .

- such misalignment may cause at least a portion of the plunger 100 and/or spring 102 to extend out of the opening 33 in the first sidewall 22 .
- Such misalignment results in jamming of the plunger 100 and/or spring 102 against a sidewall, or against a portion of the perimeter 37 of the opening 33 . It can also cause jamming and misalignment of the cartridge 70 and/or paper products therein.

Abstract
The present invention provides a container for dispensing individual paper products that includes a housing, a cover hingedly or removably attached to the housing wherein the cover defines a dispensing opening, a means for elevating paper products, and a plunger disposed in the interior area of the housing. The plunger is urged toward the dispensing opening by the means for elevating paper products. The container may be included in a system for dispensing paper products that further includes a cartridge containing paper products. The cartridge defines a dispensing opening and a second opening wherein the means for elevating paper products extends through the second opening into the interior area of the cartridge to contact the paper products and urge the paper products toward the dispensing opening. The cartridge and container may be configured wherein the second opening is formed by separation of an internal platform during the process of inserting the cartridge into the container.
Description
- Various types of dispensers for paper products have been developed to provide ready availability of the paper products to users. Such dispensers are often provided in public places such as restaurants or rest rooms where customers remove from the dispenser a desired amount of paper products for personal use. In some high traffic areas, such as fast food restaurants, a large number of customers may use a paper product dispenser such as a napkin dispenser in a short period of time. Therefore, dispensers have been developed that hold a large number of paper products for use by a large number of consumers.
- For many applications, it is desirable to have a large dispenser that is embedded in a countertop. This is particularly desirable when open counter space above the countertop is needed for visibility or other reasons. Unfortunately, large recessed dispensers are subject to a number of drawbacks. First, because access to the body of the dispenser is limited by the structure supporting the countertop, it can be difficult to load large quantities of napkins into a recessed dispenser. Second, if paper products are not properly loaded into the dispenser, the paper products may jam as they are removed thereby preventing further removal of paper products by users. Third, a person refilling a large dispenser is more likely, due to the larger number of paper products involved, to drop some of the paper products onto a floor. Any dropped paper products are then unsanitary and must be discarded, thereby creating more waste and defeating certain benefits of the larger dispenser.
- Therefore, there is a need for large inverted and/or recessed dispensers that reduce the incidence of waste of paper products due to dropping of the paper products during refilling of the container. There is likewise a need for such dispensers that reduce the incidence of jamming of paper products and the resultant inability to dispense further paper products, and further that supports the weight of paper products and moves the paper products toward the dispenser opening so that individual paper products are readily removed.
- The aforesaid needs are fulfilled and the problems experienced by those skilled in the art overcome by the system for dispensing individual paper products of the present invention. In one embodiment, a system for dispensing individual paper products is provided. The system comprises a container including a housing having side walls and a bottom wall defining an interior surface and an interior area within the interior surface. The container also includes a cover hingedly or removably attached to the housing wherein the cover defines a dispensing opening. The container also includes a spring having coils disposed in the interior area of the housing, and a plunger disposed in the interior area of the housing. The container further comprises a chain positioned inside of the coils of the spring. The chain is configured to provide tension and to maintain the spring and plunger in an aligned dispensing position in the interior area of the container to enhance dispensing of paper products from the container. The chain is coupled at one end to the plunger and at an opposite end to the housing. The chain includes a covering having a plurality of slits therein extending over the chain, the covering cooperating to cover links in the chain and the slits cooperating to un-cover each inter-linking section. The spring is compressed between the plunger and at least one of the walls, and the plunger is urged toward the dispensing opening by the spring. The chain having the covering with the plurality of slits therein controls the tension and maintains the alignment of the spring such that the spring's decompression is regulated to assist in providing the dispensing alignment of the spring and plunger within the interior are so that the spring and plunger do not become misaligned such that jamming and dispensing failure occur. The covering with the plurality of slits is positioned over the chain and configured to resist the effects of gravity to allow the chain to uncoil without effecting the tensioning of the spring and to prevent the chain from becoming caught between the coils of the spring thereby causing the spring to jam and fail to decompress. The chain with the covering and plurality of slits therein is positioned to maintain the spring and plunger in the dispensing direction. The system also includes a cartridge containing paper products. The cartridge is positioned at least partially within the interior area of the container. The cartridge defines an internal platform. The internal platform is configured to become separated from the cartridge by contact with the plunger when the cartridge is inserted in the container. The separation of the internal platform creates a second opening. After the internal platform is separated from the cartridge, the plunger extends through the second opening into the cartridge to urge the internal platform to contact the paper products and urge the paper products toward the dispensing opening.
- In a further aspect of the invention a system for dispensing individual paper products is provided. The system comprises a container including a housing including side walls and a bottom wall defining an interior surface and an interior area within the interior surface. The container includes a cover hingedly or removably attached to the housing. The cover defines a dispensing opening. The container also includes a spring having coils disposed in the interior area of the housing and a plunger disposed in the interior area of the housing. The container further includes a telescoping cylinder assembly coupled at one end to the plunger and at an opposite end to a portion of the housing. The telescoping cylinder assembly is positioned inside of the coils of the spring to provide tension to the spring and to maintain the spring and plunger in an aligned dispensing position in the interior area. The spring is compressed between the plunger and at least one of the walls, and the plunger is urged toward the dispensing opening by the spring. The telescoping cylinder assembly is configured to tension and maintain alignment of the spring such that the spring's decompression is regulated so that the spring and plunger do not become misaligned and jammed such that dispensing failure occurs. The telescoping cylinder assembly is configured to resist the effects of gravity and to maintain the spring and plunger's movement in the dispensing direction to facilitate the dispensing of paper products. The system also includes a cartridge containing paper products. The cartridge is positioned at least partially within the interior area of the container. The cartridge defines an internal platform. The internal platform is configured to become separated from the cartridge by contact with the plunger when the cartridge is inserted in the container. Separation of the internal platform creates a second opening. After the internal platform is separated from the cartridge, the plunger extends through the second opening into the cartridge to urge the internal platform to contact the paper products and urge the paper products toward the dispensing opening.
- Other features and aspects of the present invention are discussed in greater detail below.

FIG. 4 , thesecond side wall 24 and thefourth side wall 28 includeprotrusions 42 extending into the interior area of thehousing 14. However, theprotrusions 42 could be disposed on any of the walls and one wall can have multiple protrusions. In those embodiments wherein pairs of protrusions are disposed on opposing walls of thehousing 14, they can be disposed at the same height or different heights (i.e., staggered). Theprotrusions 42 may comprise a generally downwardly angled structure and may have a geometric and/or curvilinear structure. By way of example only, the protrusions may comprise curved bumpers that may include a plurality of ridges extending across the curved bumpers perpendicular to the dispensing direction. Theprotrusions 42 extend into theinterior area 32 to contactpaper products 12 and thereby oppose the movement ofpaper products 12 in the dispensing direction. By extending into theinterior area 32 to contactpaper products 12, theprotrusions 42 impede the movement ofpaper products 12 toward the dispensing opening, but do not prohibit such movement. The use of protrusions to control dispensing is described, for example, in U.S. Pat. No. 6,241,118 to Tramontina and U.S. Pat. No. 6,378,726 to Chan et al., the entire contents of which are incorporated herein by reference thereto. - Referring now to
FIG. 2 , thehousing 14 is supported within theside wall surface 16 byflanges 44 that extend outwardly from theside walls housing 14 is inserted in an opening in thecountertop 16 slightly larger than the cross-section of thehousing 14, the housing is supported within the countertop by theflanges 44. Desirably, theflanges 44 intersect theside walls bottom wall 20. This allows thecontainer 10 to be seated substantially flush with the surface of thecountertop 16. Theflanges 44 may be fastened to the countertop or other surface by suitable fasteners and/or fastening devices. Suitable fastening devices include, but are not limited to, screws, nuts and bolts, rivets, snap-fits, tacks, nails, adhesives, and so forth. - As noted above, the
cover 34 may be hingedly attached to one of theside walls hinge 46. As used herein, the term “hinge” refers to a jointed or flexible device that connects and permits pivoting or turning of a part to a stationary component. Hinges include, but are not limited to, pivotable connectors, such as those used to fasten a door to frame, and living hinges. Living hinges may be constructed from plastic and formed integrally between two members. A living hinge permits pivotable movement of one member in relation to another connected member. Thecover 34 is openable for insertion ofpaper products 12 into theinterior area 32 of thehousing 14 when the supply of paper products is depleted and/or runs low. Thefastener 36 that holds thecover 34 closed may, for example, include interlockingtabs 48. At least one of the interlockingtabs 48 is movable when desired to reopen thecover 34 by pressing thebutton 38 to release the connection of thetabs 48. Any other type offastener 36 known to those skilled in the art for reopenably securing thecover 34 may be used. - Desirably, the
cover 34 further includes a group ofcontrol ribs 52 that extend into theinterior area 32 to contact paper products when the cover is in the closed position. Thecontrol ribs 52 space, slow, align, and/or support paper products as the same are moved toward thecover 34 and through the dispensingopening 40. Size, shape, and spacing of the control ribs can be used to control dispensing of the paper products. Referring now toFIG. 5 , thecontrol ribs 52 may have different dimensions to properly support and guide the paper products into the dispensingopening 40. For example, atall rib member 56 extends into theinterior area 32 by a greater amount than ashort rib member 58. Thetall rib members 56 andshort rib members 58 are illustrated to show an exemplary dispensing configuration. Additionally, aside surface 60 of thetall rib member 56 closest to theinterior surface 30 may be configured so there is little or no offset from the interior surface. Aside surface 62 of theshort rib member 58 may be offset from theinterior surface 30 by a greater amount. - As one example, the
tall rib member 56 may have a height ranging from about 1 to about 2 inches at the location where it intersects with thefirst side wall 22 and an offset or height ranging from about 0.1 to about 0.5 inch adjacent the dispensingopening 40. Theshort rib member 58 may have a height ranging from about 0.5 to about 1.5 inch at the location where it intersects with thethird side wall 26 and an offset or height ranging from 0 to about 0.25 inch adjacent the dispensingopening 40. The rib members may have various widths or thicknesses and the width of a rib member may vary along any dimension or dimensions. Desirably, the portion of the rib member contacting the paper product will be relatively thin and smooth to minimize friction. The use of rib members is further described in U.S. Pat. No. 6,241,118 to Tramontina and PCT Publication WO 99/30601, the entire contents of which are incorporated herein by reference. - Referring to
FIGS. 2 and 6 , thecontainer 10 further includes a means for elevatingpaper products 50 toward the dispensingopening 40 in thecover 34. Various alternatives are possible within the scope of the invention to elevate paper products toward thecover 34. The means for elevatingpaper products 50 may comprise any structure that allows paper products to be urged toward and dispensed from the dispensingopening 40 in thecover 34. The means for elevatingpaper products 50 is discussed more fully below in conjunction withFIG. 5 . - The dispensing
opening 40 may have many shapes within the scope of the present invention, as long as the opening provides easy access for a user. Optionally, the dispensing opening may also be configured to provide metered delivery of individual paper products. Desirably, thepaper products 12 are interfolded, tabbed, or tab interfolded to provide metered feeding of individual paper products one at a time. Folding devices, such as boards or plates, have long been used to longitudinally fold webs and other sheet-like materials in order to form a stack of folded sheets. The sheets are, generally speaking, drawn over the folding device wherein the shape and configuration of the device causes the sheet to twist and bend thereby producing the desired fold. Folding devices have heretofore been provided in a variety of shapes and configurations in order to achieve the desired fold lines and folding patterns. Folding devices have been used to form a number of different folds including, for example, half-folds, quarter folds, c-folds, v-folds, j-folds, w-folds, z-folds, and so forth. - In addition, for more complex folds requiring multiple fold lines, it is known to form the necessary fold lines using two or more folding devices in series. In this regard, folding boards have also been used in series to achieve inter-folded or inter-leafed sheets, that is to say sheets folded such that they partially envelope portions of another sheet. Inter-leafed sheets are commonly employed in stacks as a mechanism to facilitate removal of the individual sheets from a dispenser. Withdrawal of a first sheet through a dispenser opening pulls the enveloped portion of a second sheet through the dispenser opening such that it extends out of the dispenser opening and is exposed. Having a portion of the subsequent sheet extending out of the dispenser opening greatly facilitates removal of the same from the dispenser by the user. By way of example only, various folding devices, folding patterns and inter-folding schemes are described in the following U.S. Pat. Nos. 3,401,928; 3,679,094; 3,817,514; 3,841,620; 4,131,271; 4,502,675; 5,868,276; 6,045,002; and 6,168,848. However, the present invention does not require the use of interfolded paper products.
- Optionally, the
housing 14 may include one ormore tabs 54 attached to theinterior surface 30 near the opening in thehousing 14 through which paper products are loaded. Thetabs 54 are dimensioned such that they inhibit a cartridge containing paper products from being loaded in an improper orientation. Thetabs 54 align with slots in a cartridge such that the slots will catch on thetabs 54 if the cartridge is not oriented properly prior to loading the cartridge into thehousing 14. When the cartridge is aligned properly, there are no slots to catch on thetabs 54 and the cartridge will slide into thehousing 14 unimpeded. - The
housing 14 may be made from numerous materials and by numerous methods known to those skilled in the art. Thehousing 14 may be made of plastic such as polyethylene, nylon, and so forth. However, other suitable materials, such as other plastics or metals, may be provided for any or all of the parts of thehousing 14. As one example, thehousing 14 may be made of an injection-molded plastic. Theprotrusions 42,control ribs 52, andtabs 54 are desirably formed integral with thehousing 14. However, theprotrusions 42,control ribs 52, andtabs 54 may be formed separately from thehousing 14 and attached later. Also, theprotrusions 42,control ribs 52, andtabs 54 may be made of different material from thehousing 14 if desired. For example, theprotrusions 42,control ribs 52, andtabs 54 may be made of a more resilient material than the materials described above, such as an elastomer or rubber. - Desirably, as mentioned above, a cartridge may be provided for holding paper products to be dispensed to a user. As shown best in
FIGS. 2, 4 and 6-8, acartridge 70 havingoutside walls 72 is provided for insertion into theinterior area 32 of thehousing 14 for containingpaper products 12 to be dispensed. The cartridge has abottom end 74 that is adapted to receive the means for elevatingpaper products 50 and a top end 76 adapted to dispensepaper products 12. Thecartridge 70 is sized to fit within theinterior area 32 of thehousing 14. Desirably, thecartridge 70 is sized to be only slightly smaller than thehousing 14 to maximize the number ofpaper products 12 contained within the cartridge. - The
cartridge 70 can hold and dispense significant numbers of individual sheets. Desirably, thecartridge 70 is sized to hold and dispense at least about 250 sheets. By way of example, thecartridge 70 can contain between about 400 and about 1000 sheets. In certain embodiments, thecartridge 70 can contain and dispense between about 700 and about 900 sheets. - Desirably, the cartridge includes a plurality of removable portions, the removal of which creates openings through the cartridge. One such detachable portion may be disposed at the
bottom end 74 of thecartridge 70, to provide aninternal platform 82. Alternatively, a separate internal platform may be provided, which may either be attached or detached from the means for elevatingpaper products 50. Detachment of the portion of thebottom end 74 of thecartridge 70, namely, theinternal platform 82, allows this portion of thecartridge 70 to receive the means for elevatingpaper products 50 when thecartridge 70 is loaded into thehousing 14. Alternatively, the removable portion may be flaps which can be folded back to create an opening. U.S. Ser. No. 10/657,386 filed Sep. 8, 2003 and U.S. Ser. No. 10/678,662 filed Oct. 3, 2003, the contents of which are hereby incorporated by reference for all purposes herein, disclose such flaps, and are hereby incorporated by reference herein for all purposes. - These applications illustrated a cartridge which includes one or more flaps disposed in a bottom end of the cartridge. The flaps are folded back prior to loading the cartridge into the housing. Folding back the flaps allows the cartridge to receive the means for elevating paper products (not shown).
- The
cartridge 70 may include at least one removable portion that can be removed to create at least one slot 88 that will prevent misalignment of the cartridge in the housing, as shown inFIG. 4 . The slots 88 are desirably positioned such that when the cartridge is improperly oriented, the slots will catch ontabs 54 positioned on the interior surface of the housing. The slots 88 may be positioned in one of theoutside walls 72 of thecartridge 70. Alternatively, the slots 88 may be positioned in the flaps (not shown) that are opened prior to insertion of thecartridge 70 in thehousing 14. If flaps are used, and opened (not shown), the flaps fold back against theoutside walls 72 of thecartridge 70 where the slots 88 would be in position to engage thetabs 54 if the cartridge is not oriented correctly. - The
cartridge 70 may include at least one of yet another removable portion at the first end wall or top end 76 of thecartridge 70 so thatpaper products 12 can be supported and aligned by thecontrol ribs 52 for dispensing through the dispensingopening 40. Removal of the removable portions createsopenings 90 through which thecontrol ribs 52 extend. - The
cartridge 70 may include at least one of another removable portion that corresponds to theprotrusions 42 in thehousing 14. The removable portions are disposed in theoutside walls 72 of thecartridge 70 so that, once the removable portions are removed,openings 92 can encompass and receive theprotrusions 42 extending from theinterior surface 30 of thehousing 14. Thus, upon removal of the removable portions and placement of thecartridge 70 in thehousing 14, theprotrusions 42 andrib members 58 contact thepaper products 12 within thecartridge 70 and act upon the paper products as described above. - The first end wall or top end 76 of the
cartridge 70 may be formed having a removable portion corresponding to the dispensingopening 40. Removal of this removable portion creates anopening 94 through which the paper products are dispensed (FIG. 4 ). - The removable portions may either be removed (or simply not formed) during manufacture of the cartridge or removed just prior to installation of the cartridge in the housing. If the removable portions are to be removed as part of the manufacturing process, the cartridge should be shipped to the user wrapped, for example in a polyethylene bag, to preserve the sterility of the paper products in the cartridge. If the removable portions are to be removed as part of the installation process, the edges of the removable portions should be weakened, scored, etc. for easy removal. If a removable portion is used to provide access for the means for elevating the paper products, it should not be removed as part of the manufacturing process to ensure that the paper products remain properly loaded in the
cartridge 70 until the time at which the cartridge is to be inserted in thehousing 14. - The
cartridge 70 is desirably made of heavy paper or cardboard. It will be understood, however, that the cartridge may be made of any suitable material known to those skilled in the art. Such suitable material(s) include, but are not limited to, cardboard, plastic, film, foil, and so forth. - Referring now to
FIGS. 2 and 6 , aplunger 100 is disposed within theinterior area 32 of thehousing 14 along with at least onespring 102. When thespring 102 is compressed by theplunger 100, thespring 102 urges theplunger 100 in the dispensingdirection 104. Thus, whenpaper products 12 are placed in thecontainer 10 and theplunger 100 is depressed thereby compressing thespring 102, theplunger 100 and thespring 102 urge thepaper products 12 toward the dispensingopening 40. Use of a plunger and spring mechanism allows thecontainer 10 to be used in situations where paper products are to be dispensed in a substantially vertical direction. - The
plunger 100 is shaped to provide support and lift thepaper products 12 through thehousing 14 without becoming stuck such that the paper products would no longer be elevated toward the dispensingopening 40. The plunger can have any one of various shapes. In one embodiment, theplunger 100 can take the shape of a truncated cone having a top surface 108 and abottom surface 110. The top surface 108 engages and lifts aninternal platform 82 against thepaper products 12. Thebottom surface 110 is engaged by thespring 102. The diameter of thebottom surface 110 is desirably substantially equivalent to the diameter of thespring 102. Desirably, thebottom surface 110 of the plunger is attached to thespring 102 to prevent disengagement of the spring from the bottom surface of the plunger. - A chain 111 also extends from and is desirably coupled to the
plunger 100. That is, one end of the chain 111 is desirably coupled to a lower surface (not shown) of theplunger 100, and the opposite end is desirably coupled to thebottom wall 20 of thecontainer 10. The chain 111 extends inside of thespring 102, that is, inside of the spiraling coils 122 of thespring 102, and it assists in controlling the decompression, alignment and tensioning of thespring 102 against theplunger 100. The chain 111 is desirably covered by aresilient covering 115 which includes a plurality ofnotches 117. - Each of the plurality of
notches 117 may desirably be positioned at the junction of one link as it couples or links to the next link in the chain 111, that is, each inter-linking section. Such positioning of each notch of the covering 115 permits the chain 111 to properly evenly uncoil to evenly regulate the movement, direction, alignment and tensioning of thespring 102 as thespring 102 is gradually decompressed when paper products are removed from the dispensingopening 40, thereby permitting theplunger 100 to continue to move in the aligned dispensing position or dispensingdirection 104 in theinterior area 32 of thecontainer 10 toward the dispensingopening 40 to enhance dispensing ofpaper products 12. When theplunger 100,spring 102 and chain 111 with covering 115 are compressed, and thecontainer 10 is oriented in a generally vertical position, the spring 111 is compressed in the generally vertical position of thecontainer 10, and the chain 111 with the covering 115 thereover collapses into itself within aninterior area 124 within the confines of thecoils 122 of thespring 102. Problems are more likely to occur, however, when thecontainer 10 is oriented in a generally horizontal or oblique position or orientation, where gravity may negatively effect theplunger 100, thespring 102 and/or the chain 111. - When the
container 10 is in the non-vertical position, alignment or orientation, theplunger 100, thespring 102 and/or the chain 111 may misalign. When thespring 102 is at least partially compressed, theplunger 100, thespring 102 and/or the chain 111 may move out of alignment and against a sidewall of thecontainer 10 or at least partially out of theopening 33 in the first side wall 22 (not shown). When this occurs, dispensing of paper products fail because theplunger 100 does not move thecartridge 70 and/orpaper products 12 up to the dispensingopening 40 in thecontainer 10 so that a user may access and remove them. In addition, if an uncovered chain falls between thecoils 122 of thespring 102, links in the chain jam or bind inbetween thecoils 122, causing thecoils 122 to bind together. When this occurs, the chain 111, because it is bound within thecoils 122, cannot properly align and tension thespring 102 andplunger 100. These events prevent thespring 102 from decompressing completely, and cause misalignment of the spring and plunger, which results in jamming of thespring 102 and/orplunger 100 and dispensing failure as well. - Therefore, so that the chain 111 may act properly to help maintain the regulated movement, direction, alignment and tensioning of the
spring 102, a solid covering was placed over the chain 111 (not shown). The solid covering, although resilient, placed too much stiffness in the chain 111. The solid covering would not permit the chain 111 to uncoil and collapse withininterior area 124 within thecompressed spring 102. Rather, the stiffness in the solid covering caused limited movement of the chain 111, so that the chain 111 could not uncoil, but would fall in stiff lengths of chain which caused binding of thespring 102. This binding again resulted in an un-even tensioning and decompression of thespring 102, which resulted in thespring 102 and/or the plunger becoming misaligned. Dispensing failure occurred again. To address this problem, the plurality ofnotches 117 was added to thecovering 115. The chain 111 having a covering 115 with a plurality ofnotches 117 now has sufficient resiliency to coil when compressed and uncoil in a regulated basis while resisting the effects of gravity to allow the chain 111 to keep from fallinginbetween coils 122 of thespring 102, thereby preventing the chain 111 from binding up thespring 102 such that thespring 102 will not decompress, resulting in jamming and dispensing failure. The chain having the covering 115 with the plurality of notches allows thespring 102 to decompress so that dispensing alignment is maintained in the dispensingdirection 104. The chain 111 and spring are maintained in theinterior area 124. The chain 111 with covering 115 havingnotches 117 controls the movement, direction, alignment and even tensioning of thespring 102 and theplunger 100 whether in a generally vertical position or whether in a substantially non-vertical position or orientation. - The chain may be formed from any suitable material, for example, metal, plastic, and so forth. Similarly, the covering 115 having notches therein is desirably formed from a resilient material which permits the chain contained therein to coil and uncoil. Such resilient materials include, for example, but not by way of limitation, rubber, plastic (such as polypropylene), nylon, and so forth.
- Desirably, one or more stabilizing
wings 112 extend from theplunger 100. Thewings 112 act to distribute the force from thespring 102 to the outer edges of theinternal platform 82. As shown inFIG. 2 , the force is applied by theupper edge 114 of thewing 112 that contacts theinternal platform 82. Thewings 112 also act to prevent theplunger 100 andspring 102 from tipping over inside the cartridge. If theplunger 100 andspring 102 begin to tip over, theouter edge 116 of thewing 112 contacts the inside surface of thecartridge 70 before the plunger can get stuck. Thus, the surface area of theouter edge 116 is desirably minimized to prevent the outer edge from binding against the inside surface of thecartridge 70. Thebevel 118 between theupper edge 114 and theouter edge 116 is configured to transition between theupper edge 114 and theouter edge 116. Thewings 112 may have various thicknesses and the thickness of the wing may vary along any dimension or dimensions. Desirably, theouter edge 116 of thewing 112 will be relatively thin and smooth to minimize friction against the inside surface of thecartridge 70. - The
plunger 100 will desirably include asmall post 125 extending outward from the center of the top surface 108 of theplunger 100. It was discovered that dispensing failures occurred when thecontainer 10 was positioned in a generally non-vertical position or orientation. That is, the effects of gravity were greater on theplunger 100 when thecontainer 10 is positioned in a horizontal or oblique position or orientation. This is because the force of gravity permitted the plunger to shift away from its desired position against theinternal platform 82. In fact, theplunger 100 sometimes moves such that it extends at least somewhat through theopening 33 in thefirst side wall 22. Theplunger 100 then binds against aperimeter 37 of theopening 33, and does not push the paper products and/or the cartridge toward theopening 40 in thecontainer 10, resulting in dispensing failure. Thepost 125 assists in maintaining the plunger in a proper dispensing alignment, particularly, but not by limitation, when thecontainer 10 is positioned in a generally horizontal or oblique position. Thepost 125 moves into contact with a cooperative andcorresponding opening 126 in theinternal platform 82. While theopening 126 is shown as a generally square-shaped opening while thepost 125 is a generally round-shaped post, it will be appreciated that thepost 125 and/or theopening 126 may assume any shape(s) or configuration(s) so long as thepost 125 and theopening 126 operate such that thepost 125 extends into theopening 126 to assist in holding theplunger 100 in a proper alignment to prevent even and un-interrupted dispensing of paper products through the dispensingopening 40 in thecontainer 10. It will be appreciated that thepost 125 andopening 126 act to hold theplunger 100 in a dispensing alignment in spite of the effects of gravity and/or other pressures or forces. - Referring again to
FIGS. 2, 6 and 9, thespring 102 is sized to provide sufficient force to urge and/or elevate thepaper products 12 to the dispensingopening 40. Desirably, the spring applies substantially constant pressure against the paper products at all positions of travel. Application of substantially constant pressure helps to prevent over application of force when the plunger is toward the bottom of the dispenser and under application of force when the plunger is toward the top of the dispenser. - As discussed above, in one embodiment of the invention the bottom of the cartridge is opened prior to insertion of the cartridge into the housing to enable the contents of the cartridge to be engaged by the means for elevating the
paper products 50 To prevent the paper products from falling out of the opening during the insertion process, the second end wall orbottom end 74 of thecartridge 70 may contain theinternal platform 82. - The
internal platform 82 is prevented from falling out of thecartridge 70 because theinternal platform 82 provides a portion of the second end wall orbottom end 74 of thecartridge 70. The internal platform is delineated by lines ofweakness 75 or perforations which permit it to be separated from the rest of thebottom end 74. The largest dimensions of theplatform 82 are desirably slightly smaller than the internal dimensions of thecartridge 70 so that the platform can move through the cartridge as paper products are dispensed without binding against the internal surface of the cartridge. Desirably, the largest dimensions of the platform may be substantially equal to or may be slightly larger than the paper products to provide uniform dispensing of the paper products. - Referring to
FIGS. 9 and 10 , thecartridge 70 is configured for insertion in acontainer 10. The cartridge includes theinternal platform 82, and thecartridge 70 is positioned to engage at least one tower 130 anchored to the inside surface of thebottom wall 20 of thehousing 14. The at least one tower 130 is positioned on the inner or inside surface of thebottom wall 20 where it will not interfere with the functioning of the means for elevatingpaper products 50. The at least one tower 130 extends from thebottom wall 20 toward the opening (not shown) in thehousing 14 through which thecartridge 70 is loaded. The length or height of the at least one tower 130 is such that it extends past theplunger 100 when the plunger has fully compressed thespring 102 below. Thus, when thecartridge 70 is inserted into thehousing 14 of thecontainer 10, compressing thespring 102, thebottom end 74 having theinternal platform 82 formed therewith contacts the top of the at least one tower 130 before the spring is fully compressed. - The at least one tower 130 includes a top 132 that contacts the
bottom end 74 when thecartridge 70 is inserted in thecontainer 10. Desirably, the top 404 of the at least one tower 130 contacts the portion or thebottom end 74 which provides theinternal platform 82 to cause theinternal platform 82 to be separated without ripping or tearing ofbottom end 74. The cross-sectional area of the top 132 of the at least one tower 130 should be selected so that the top will separate theinternal platform 82 from the remainingbottom end 74 rather than puncturing theinternal platform 82. For example, the cross-sectional area of the top 132 may be greater than 0.5 cm2, and desirably may be greater than 1 cm2. Desirably, as many towers 130 may be used as are necessary to provide a clean separation along the lines ofweakness 75 of theinternal platform 82 from thebottom end 74. In a particularly desirably configuration, four towers 130 are positioned at or near thecorners 134 of theinternal platform 82. - To load a
cartridge 70 having abottom end 74 with aninternal platform 82 that does not require removal prior to loading, thecartridge 70 is inserted into thecontainer 10 with thebottom end 74 facing against the means for elevatingpaper products 50. As an example, thebottom end 74 of thecartridge 70 having theinternal platform 82 capable of receiving the means for elevatingpaper products 50 can be positioned against theplunger 100 attached to thespring 102 within thecontainer 10. Specifically, thepost 125 on the top surface 108 of theplunger 100 is desirably positioned into theopening 126 in thebottom end 74 of thecartridge 70. Thecartridge 70 is then pushed down against theplunger 100, depressing theplunger 100 against thespring 102 until the cartridge is nearly seated in thehousing 14 of thecontainer 10. Just prior to thecartridge 70 being fully seated, theinternal platform 82 is separated via the lines ofweakness 75 from thebottom end 74 of thecartridge 70 by either the fully compressedplunger 100 or, if present, the at least one tower 130. In this regard, the force on theinternal platform 82 exerted by either the spring-loadedplunger 100 or the at least one tower 130 exceeds the perforation strength of the lines ofweakness 75 defining and restraining theinternal platform 82 in thebottom end 74 of thecartridge 70, and theinternal platform 82 becomes separated therefrom. Once theinternal platform 82 becomes separated from thebottom end 74 of thecartridge 70, thereby creating a second opening into thecartridge 70. Theinternal platform 82 provides support to thepaper products 12 as thepaper products 14 are urged towards thedispenser opening 40. Theplunger 100 is then moved through the second opening into thecartridge 70 to urge theinternal platform 82 to contact the paper products and urge the paper products toward the dispensingopening 40. - Another embodiment of the invention is illustrated in
FIGS. 3, 5 , 7 and 8. This embodiment employs a plurality ofcylinders 140 that are positioned in an interlocking and telescoping arrangement, rather than the chain 111 having a covering 115 with a plurality ofnotches 117. The plurality ofcylinders 140 are positioned so that the largest diameter cylinder is coupled to thebottom wall 20 of thecontainer 10, while the smallest diameter cylinder is coupled to the lower surface of the plunger 100 (not shown). Thetelescoping cylindrer assembly 150 is provided in theinterior area 124 of thespring 102, and, along with the spring and the plunger, provides an alternative means for elevatingpaper products 50. - The
telescoping cylinder assembly 150 is used in place of a chain, to regulate and control movement, direction, alignment and tensioning of thespring 102. Thetelescoping cylinder assembly 150 is useful when thecontainer 10 is positioned in any position or orientation. However, thetelescoping cylinder assembly 150 is most helpful to counteract the negative effects of gravity when thecontainer 10 is positioned in a non-vertical position or orientation. - When the
container 10 is positioned in a generally horizontal or in an oblique position or orientation, theplunger 100 andspring 102 are affected by gravity, which can negatively impact dispensing performance. As discussed previously, thespring 102 and/orplunger 100 has a tendency to become misaligned in theinterior area 32 of thecontainer 10 when thecontainer 10 is not generally vertically oriented. Such misalignment can cause at least a portion of theplunger 100 and/orspring 102 to jam against a sidewall of thehousing 12. Alternatively, such misalignment may cause at least a portion of theplunger 100 and/orspring 102 to extend out of theopening 33 in thefirst sidewall 22. Such misalignment results in jamming of theplunger 100 and/orspring 102 against a sidewall, or against a portion of theperimeter 37 of theopening 33. It can also cause jamming and misalignment of thecartridge 70 and/or paper products therein. Dispensing failure results, since theplunger 100 does not continue to move theinternal platform 82 and therefore the paper products closer to the dispensingopening 40 as paper products are removed from thecontainer 10. - The
telescoping cylinder assembly 150 is positioned to hold thespring 102 andplunger 100 in proper dispensing alignment., whether the container is in a substantially vertical position or in a non-vertical position, such as a horizontal or oblique position or orientation. The alignment of thespring 102 andplunger 100 is maintained, in spite of the forces of gravity, because thecylinders 140 are formed from a generally stiff, non-resilient but light-weight material, such as, for example only, plastic and/or metal. Any suitable material or combination of materials may be used, however, so long as the telescoping cylinder assembly operates as described herein. - The
telescoping cylinder assembly 150 positioned inside of thecoils 122 of thespring 102 provide tension to thespring 102 and maintain thespring 102 and theplunger 100 in an aligned dispensing position in theinterior area 32 of thecontainer 10 and in alignment with the dispensingdirection 104. The telescoping cylinder assembly provides tension to thespring 102 and regulates the tension such that the spring's decompression is regulated and the spring's alignment is regulated to prevent misalignment and jamming of thespring 102 and/or theplunger 100, so that dispensing failure does not occur. Thetelescoping cylinder assembly 150 is configured to resist the effects of gravity to maintain the spring and plunger's movement in the dispensingdirection 104 to facilitate dispensing ofpaper products 12. Therefore, thetelescoping cylinder assembly 150 directs theplunger 100 andspring 102 such that gravity has less effect on each of them. In addition, thepost 125 on the top surface 108 of theplunger 100 is positioned to extend into theopening 126 in thecartridge 70 to assist in holding theplunger 100 in a proper alignment within theinterior area 32 of thecontainer 10. - Referring to
FIGS. 5, 9 and 10, the cartridge 70 (FIGS. 7 and 8 ) includes the same configuration for insertion in acontainer 10 having a telescoping cylinder assembly 150 (FIG. 5 ). As shown inFIGS. 9 and 10 , thecartridge 70 includes theinternal platform 82, and thecartridge 70 is desirably positioned to engage the top 132 of at least one tower 130 anchored to the inside surface of thebottom wall 20 of thehousing 14. The at least on tower 130 is positioned on the inside surface of thebottom wall 20 where it will not interfere with the functioning of the means for elevatingpaper products 50, including thetelescoping cylinder assembly 150. The at least one tower 130 extends from thebottom wall 20 toward the opening (not shown) in thehousing 14 through which thecartridge 70 is loaded. The length or height of the at least one tower 130 is desirably such that it extends past theplunger 100 when the plunger has fully compressed thespring 102 below. Thus, when thecartridge 70 is inserted into thehousing 14 of thecontainer 10, compressing thespring 102, thebottom end 74 having theinternal platform 82 formed therewith contacts the top of the at least one tower 402 before the spring is fully compressed. - Like the
compressed spring 102, thetelescoping cylinder assembly 150 is designed to telescope into a stack ofcylinders 140 when thespring 102 is compressed. The stack ofcylinders 140 are configured to be of a height or length which do not interfere with the function of the at least one tower 130. The stack ofcylinders 140 are positioned against or adjacent abottom wall 20. Aspaper product 14 is removed from thecontainer 10 and thespring 102 decompresses, the telescoping cylinder assembly extends from thebottom wall 20 to provide controlled tensioning, direction (dispensing direction), alignment and support of thespring 102 between thebottom wall 20 of thecontainer 10 and thebottom surface 110 of theplunger 100, as illustrated inFIGS. 3 and 5 . The at least one tower 130 includes the same characteristics and features, and operates in the same manner as described previously herein Similarly, thecartridge 70 is loaded in the same manner into acontainer 10, and the at least one tower 130, and desirably, four towers 130, operates as previously shown and described herein. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit of the invention. It is intended that the present invention include such modifications and variations as come within the scope of the appended claims and their equivalents.
