- a feature of the enclosure is allowing first and second ridges of the outer seal to gradually diverge from a sealed position to ultimately engage the periphery of the end portion.
- Another feature of the enclosure is opposing planar side walls that extend from a base portion of the sealing members to ultimately converge to form an edge that snugly engages a sealed portion of the outer seal.

- the vacuum device 18 is then energized to remove all air from the inner and outer portions 12 and 16 of the enclosure 10 thereby forcing the enclosure to collapse upon the goods 14 as depicted in FIG. 5, whereupon, the inner seal 24 is closed to provide an air tight barrier between the inner and outer portions 12 and 16 resulting in vacuum packed perishable goods 14 .
- the end portion 22 of the vacuum device 18 is then removed from the outer portion 16 and the outer seal 20 is closed to provide a second barrier to air that might engage the perishable goods 14 .

Description
- 1. Field of the Invention
- The present invention relates to enclosures that encase perishable food goods such as “leftovers” from a large dinner for freezing and more particularly, to deformable enclosures such as freezer bags that have the air removed from an inner portion containing the goods, then sealed air tight thereby “vacuum packing” the goods for freezing.
- 2. Background of the Prior Art
- Freezer bags and other deformable enclosures are routinely used to encase perishable goods before freezing. When freezer bags are used, it is common practice to place the goods in the bag without removing the air in the bag before freezing. This practice results in the food becoming damaged when left in a frozen state for long periods of time. There are deformable food enclosures designed to cooperate with relatively expensive vacuum devices to remove air from the enclosure. The problem with these food enclosure designs is that the enclosures and device are cumbersome to use and store, expensive and difficult to operate.
- Therefore, a deformable enclosure is required that is common and inexpensive such as a standard freezer bag, and that can utilize a common vacuum device such as a home vacuum cleaner to remove the air from the enclosure. Further, the portion of the enclosure encasing the food must be capable of being sealed air tight while the vacuum cleaner is inside the enclosure, and a predetermined distance between portions of the enclosure proximate to an air removal port of the vacuum cleaner must be maintained to prevent the enclosure from being sucked into the port when the vacuum cleaner is energized.
- It is an object of the present invention to overcome many of the disadvantages associated with removing air from enclosures to preserve perishable goods.
- A principle object of the present invention is to provide an enclosure that allows a vacuum device such as a home vacuum cleaner to remove air from the enclosure. A feature of the enclosure is that it is deformable. An advantage of the enclosure is that an open portion can tightly engage an end portion of the vacuum device that includes an air removal port.
- Another object of the present invention is to prevent air from entering the enclosure as the end portion of the vacuum device is removed from the enclosure. A feature of the enclosure is inner and outer internal seals that form inner and outer portions in the enclosure. An advantage of the enclosure is that only the outer seal engages the vacuum device thereby allowing the inner seal to be closed before the vacuum device is removed from the outer seal to maintain the vacuum in the inner portion where the perishable goods are disposed.
- Yet another object of the present invention is to provide sealing members that congruently engage the air removal or end portion of the vacuum device to facilitate a tight seal between the end portion and the outer seal of the enclosure. A feature of the enclosure is allowing first and second ridges of the outer seal to gradually diverge from a sealed position to ultimately engage the periphery of the end portion. Another feature of the enclosure is opposing planar side walls that extend from a base portion of the sealing members to ultimately converge to form an edge that snugly engages a sealed portion of the outer seal. An advantage of the enclosure is that a smooth transition occurs for the outer seal from a closed to a fully open cylindrical configuration to prevent a small opening that would otherwise occur between the sealed portion of the outer seal and the cylindrical end portion of the vacuum device.
- Another object of the present invention is to separate the enclosure from the air removal port of the end portion of the vacuum device a distance that prevents the enclosure from obstructing air removal by the vacuum device from the inner and outer portions of the enclosure. A feature of the enclosure is to provide sealing members with opposing inner and outer parallel side walls separated a distance that disposes the inner side wall inside the outer portion of the enclosure between the inner and outer seals, and that disposes the outer side wall beyond the outer seal between griping flaps. An advantage of the enclosure is to prevent a portion of the enclosure from being sucked into the air removal port of the vacuum device irrespective of the suction force generated by the vacuum device. Another advantage of the enclosure is to maintain vacuum in an inner portion of the enclosure by maintaining engagement between the converging side walls and first and second ridges of the outer seal irrespective of the vibration generated by the vacuum device.
- Briefly, the invention provides an enclosure for preserving perishable goods comprising an inner portion for removably receiving perishable goods; an outer portion that removably receives a vacuum device that promotes the removal of air from said enclosure after the perishable goods have been inserted into said inner portion; outer seal means for providing an air tight seal between said enclosure and the vacuum device to promote the removal of air from said enclosure; and inner seal means for providing an air tight seal for said inner portion and the goods therein after the removal of air from said enclosure and while the vacuum device remains engaged with said outer seal means, the vacuum device being separated from said outer seal means after the removal of air from said inner portion and the air tight sealing of said inner seal

numeral 10. Theenclosure 10, which includes freezer bag configurations, is fabricated from plastic or similar deformable material that is light weight and relatively durable when exposed to temperatures ranging from freezing to boiling. Theenclosure 10 includes an inner orfirst portion 12 for removably receivingperishable goods 14, an outer orsecond portion 16 that removably receives a vacuum orair removing device 18 such as a vacuum cleaner, which removes air from theenclosure 10 after theperishable goods 14 have been inserted into theinner portion 12, a re-sealableouter seal 20 that provides an air tight boundary between theenclosure 10 and anend portion 22 of thevacuum device 18 to promote the removal of air from theenclosure 10, and an internal, re-sealableinner seal 24 that provides an air tight boundary for theinner portion 12 and thegoods 14 therein after the removal of air from theenclosure 10 and while thevacuum device 18 remains engaged with theouter seal 20; thevacuum device 18 being separated from theouter seal 20 after the removal of air from theinner portion 12 and the air tight sealing of theinner seal 24 whereby theperishable goods 14 are encased in a vacuum sealedinner portion 12 of theenclosure 10 to preserve theperishable goods 14 after freezing thegoods 14. - The
enclosure 10 can be dimensioned to encase anyperishable goods 14, but typically ranges from a “sandwich” size to a much larger “meal” size that is capable of holding an entire dinner. Theenclosure 10 further includes opposinggripping flaps 26 that are integrally joined to theouter seal 20 and dimensioned to provide a means for a person to grip theenclosure 10 and separate theouter seal 20 after theenclosure 10 and the contents therein have been frozen. Once theouter seal 20 has been opened, it is relatively easy to open theinner seal 24 even when theenclosure 10 and contents therein are frozen. - The
vacuum device 18 includes, but is not limited to, a vacuum cleaner having a hose with atubular end portion 22 that typically includes a cylindrical configuration with anair removal port 28. Thevacuum device 18 possesses sufficient power to facilitate the removal of air from theenclosure 10, but not so much power so as to result in theenclosure 10 being sucked into theend portion 22. - Referring to FIGS. 1, 6 and7, the
inner portion 12 is sized to receivedpreselected goods 14 such that when thegoods 14 are inserted into theinner portion 12, a sufficientinner portion 12 volume remains to minimize deformation and obstruction of theinner seal 24 thereby facilitating an air tight boundary between the inner andouter portions inner seal 24 is typical of the seals used for single seal freezer bags and includes opposing first andsecond ridges second walls enclosure 10. Thefirst ridge 30 includes two relatively firm, plastic protuberances extending perpendicularly from the firstinner wall 34, a distance that promotes the complete insertion of the opposing relatively firmsecond ridge 32, which extends perpendicularly from the innersecond wall 36, between the two protuberances of the first ridge 30 (see FIG. 8). - Referring to FIGS. 2-5, the
outer portion 16 is sized to receive theend portion 22 of thevacuum device 18 such that theair removal port 28 is disposed at substantially a central portion of theouter portion 16 with theair removal port 28 being spaced from the inner seal 24 a distance that facilitates the unobstructed sealing of theinner seal 24 while theend portion 22 remains disposed between the outer andinner seals outer seal 20 is typical of the seals used for single seal freezer bags and includes the same configuration as theinner seal 24. More specifically, opposing first andsecond ridges second walls enclosure 10. Thefirst ridge 30 includes two relatively firm, plastic protuberances extending perpendicularly from the firstinner wall 34, a distance that promotes the complete insertion of the opposingsecond ridge 32, which extends perpendicularly from the innersecond wall 36, between the two protuberances of the first ridge 30 (see FIGS. 7 and 8). - In operation, a freezer
bag type enclosure 10 is selected to receiveperishable goods 14 having a predetermined size and quantity. The outer andinner seals goods 14 to be disposed in aninner portion 12 of theenclosure 10. Next, anend portion 22 of avacuum device 18 is positioned between the outer andinner seals air removal port 28 is disposed at a central portion of anouter portion 16 of theenclosure 10. Theouter seal 20 is then closed such that the periphery of theend portion 22 of thevacuum device 18 is tightly and continuously engaged by theouter seal 20 to maintain an air tight seal even with theend portion 22 of thevacuum device 18 protruding through theouter seal 20. Thevacuum device 18 is then energized to remove all air from the inner andouter portions enclosure 10 thereby forcing the enclosure to collapse upon thegoods 14 as depicted in FIG. 5, whereupon, theinner seal 24 is closed to provide an air tight barrier between the inner andouter portions perishable goods 14. Theend portion 22 of thevacuum device 18 is then removed from theouter portion 16 and theouter seal 20 is closed to provide a second barrier to air that might engage theperishable goods 14. Theenclosure 10 and its contents are then frozen to preserve thegoods 14 until theenclosure 10 is unsealed and thegoods 14 removed for consumption. - Referring now to FIGS. 9 and 10, two sealing
members 40 are depicted congruently engaging an air removal orend portion 22 of thevacuum device 18 to facilitate a tight seal between theend portion 22 and theouter seal 20 of theenclosure 10 by allowing the first andsecond ridges outer seal 20 to gradually diverge or separate from a sealed position to engagement with respective inclined convergingside walls 46 of the sealingmembers 40 and also with the periphery of theend portion 22. The gradual diverging of theridges outer seal 20 from a closed to an open configuration that seals about a small portion of theend portion 22 of thevacuum device 18. Without the two sealingmembers 40, a tightouter seal 20 would be difficult to achieve due to the cylindrical configuration of the periphery of theend portion 22, resulting in small openings between the sealed portion of theouter seal 20 and theend portion 22. - The sealing
members 40 are fabricated from a relatively firm material such as rubber. The sealingmembers 40 have a relatively triangular configuration that includes anarcuate base portion 42 that congruently engages a cylindrically configuredouter side wall 44 of theend portion 22 of thevacuum device 18. The sealingmembers 40 further include opposingplanar side walls 46 that extend from thebase portion 42 and ultimately converge to form anedge 48 that snugly engages a sealedportion 50 of theouter seal 20. The convergingside walls 46 have a lateral dimension that separates opposing inner and outerparallel side walls 52 and 54 a distance that disposes theinner side wall 52 inside the outer portion of the enclosure a distance that prevents theouter portion 16 of theenclosure 10 from being sucked into theair removal port 28 of theend portion 22 of thevacuum device 18 irrespective of the air removal force generated by thevacuum device 18; and that disposes theouter side wall 54 sufficiently beyond theouter seal 20 between thegripping flaps 26 to maintain engagement between the convergingside walls 46 and the first andsecond ridges outer seal 20 irrespective of the vibration generated by thevacuum device 18. - Referring now to
drawings freezer bag 10 in conformance with the present invention, is denoted asnumeral 70. Thealternative device 70 includes a hand heldvacuum portion 72, well known and commercially available, that includes anend portion 74 with an orifice (not pictured), afunnel member 76 that is joined to a connection member 78 which is secured to theend portion 74 via a securingstrap 80 made from velcro or similar self locking material, and atube member 82 having a sufficient longitudinal dimension to dispose anorifice 84 within theouter portion 16 of thebag 10 while the funnel member is disposed beyond the gripping flaps 26. - The connection member78 is fabricated from plastic or similar material and functions as an interfacing device for the
suction device 70 and thefunnel member 76, also fabricated from plastic. The connection member 78 is tightly secured to thesuction device 70 by thestrap 80 upon snugly sliding an end portion 81 of the connection member 78 upon a cooperating portion of thedevice 70. The connection member 78 slidably receives thefunnel member 76 by snugly inserting anend portion 83 of thefunnel member 76 into a relatively larger receiving end 86 of the connection member 78. - The
tube member 82 is integrally joined to thefunnel member 76 and is ultimately disposed such that theorifice 84 is positioned between the outer andinner seals inner portion 12 of thebag 10. Thetube member 82 is fabricated from plastic and, when taking an end view, configured in the shape of an oval with a substantially larger longitudinal axis relative to a lateral axis thereby providing a substantially “flattened” tube that facilitates a tightouter seal 20 when the first andsecond ridges tube member 82 when removing air from theinner portion 12 of thebag 10. Theorifice 84 has a relatively small cross-sectional area thereby limiting the vacuum capability of thevacuum portion 72 to prevent theinner portion 12 of thebag 10 from being drawn into thetube member 82 when using a relativelypowerful vacuum portion 72. - Referring now to FIG. 12a, an alternative design for the
suction device 70 in accordance with the present invention, is depicted and denoted as numeral 90. The alternative design 90 includes a connectingmember 92 configures to snugly insert into a suction orifice in thevacuum portion 72, and an extension tube 94 integrally joined to the connectingmember 92. The extension tube 94 is substantially longer than thetube 82 of thealternative suction device 70 to allow an operator to grasp the tube 94 while removing air from theinner portion 12 of abag 10 via anorifice 96 which includes the same cross-sectional configuration as the alternativedevice tube member 82. - Referring now to FIG. 13, an alternative bag or food enclosure in accordance with the present invention, is depicted and denoted as
numeral 100. Thealternative bag 100 is designed to stand upright while removing air from within thereby promoting the removal of air without drawing thebag 100 into the vacuum suction port. Thebag 100 includes aninner portion 102, anouter portion 106, an outer seal 108, an inner seal 110, grippingflaps 112, abottom wall 114, twoside walls 116 and two end walls 118. The inner andouter portions vacuum portion 72 to remove air from theinner portion 102 by disposing theorifice 84 of thevacuum portion 72 between the outer and inner seals 108 and 110. Upon removing the air from theinner portion 102, theinner seal 10 is closed, thetube member 82 of thevacuum portion 72 removed, and the outer seal closed to prevent air from seeping into thebag 100. An addedseal 120 is provided in thegripping flaps 112 to further restrict air from seeping into thebag 100.Outer portions 122 of thegripping flaps 112 are sufficiently sized to grasp and forcibly open the addedseal 120 and ultimately the outer and inner seals 108 and 110 to gain access to the frozen contents inside thebag 100. - The upright stance of the
bag 100 is accomplished by incorporating a triangular configuration into the end walls 118. Triangular configuredseams 124 are included in the end walls 118 to promote the collapsing of the end walls 118 as air is forcibly sucked from thebag 100. As air is removed from thebag 100, the end walls 118 start collapsing inward at acentral point 126 in theseams 124. The end walls 118 continue to collapse until thecentral points 126 engage the food goods to be frozen, whereupon, the bottom andside walls bag 100 prevents theside walls 114 from first collapsing and being drawn into theorifice 84 of thevacuum portion 72 before the air has been removed from thebag 100 thereby promoting a complete vacuum of thebag 100 and the preservation of the food goods therein. - The foregoing description is for purposes of illustrating only and is not intended to limit the scope of protection accorded this invention. The scope of protection is to be measured by the following claims, which should be interpreted as broadly as the inventive contribution permits.
