- venting feature 30 includes a venting tape 35 positioned over an area 13 of side panel 14 having fluid passageways or vents 100 therethrough.
- FIG. 2 illustrates a portion of venting tape 35 removed from area 13 , thus exposing vents 100 in side panel 14 .
- Venting tape 35 is attached to side panel 14 in a manner allowing fluid passages 40 between tape 35 and side panel 14 .
- Venting feature 30 specifically venting tape 35 and vents 100 , provides a path for fluid flow from interior 20 of package 10 to the exterior of package 10 .
- the fluid to pass through venting feature 30 can be either or both gaseous or liquid. In most uses of package 10 , the fluid passing through venting feature 30 will be air with some entrained moisture.
- Vents 100 in area 13 may be any suitable shape or size, although the vents will generally be less than about 5 mm in their largest dimension, often less than about 3 mm.
- Three alternate configurations for vents 100 are illustrated in FIG. 3 .
- a first embodiment for vents 100 is crosses 110 . In this configuration, no material from side panel 14 is removed; rather, side panel 14 is merely cut, slit, punched or otherwise ruptured to allow air to flow through crosses 110 .

Each passage 40 is positioned between two adjacent attachment regions 45 .
- attachment regions 45 extend at least along the edges of venting tape 35 and preferably provide sufficient volume therebetween for fluid flow. Adherence of venting tape 35 to side panel 14 may be facilitated by adhesive in attachment regions 45 ; however, it is preferred not to have adhesive across the entire surface of venting tape 35 , as it will inhibit air flow.
- FIG. 4 illustrates fluid flow 60 through passages 40 .
- Venting feature 30 allows fluid, e.g., air, to be expelled from interior 20 while zipper closure 50 is sealed.
- the combination of vents 100 in surrounding wall 11 , (e.g., in side panel 14 ) and venting tape 35 , particularly passages 40 control the rate of fluid flow from interior 20 . It is understood that the flow through vents 100 and passages 40 can be modified by altering the characteristic, e.g., the dimensions, shaped, spacing, etc. of vents 100 and/or passages 40 .
- venting tape 35 is positioned on an exterior surface of side panel 14 ; it is understood that venting tape 35 could alternately be positioned on the interior surface of area 13 . It is believed that when venting tape 35 is positioned on the exterior of side panel 14 , air can easily pass out via venting feature 30 when pressure is applied, but air movement into interior 20 is difficult, which reduces the ingress of contaminants from outside of package 10 . It is also believed that when venting tape 35 is positioned on the exterior of side panel 14 , air can easily pass out from interior 20 via venting feature 30 when pressure is applied, but the flow of liquid is restricted.
- package 10 could optionally include a sealant stripe, such as a peal seal, which can be sealed, readily opened, and resealed, on an interior surface of surrounding wall 11 , such as panels 12 , 14 , in close proximity to zipper closure 50 .
- a sealant stripe such as a peal seal
- peal seals include those described in U.S. Pat. Nos. 6,290,393; 6,210,038, and 6,131, 248, each of which is incorporated herein by reference.
- package 10 could include a textured stand-off area in surrounding wall 11 , such as in one or both of panel 12 , 14 .
- a textured stand-off area is particularly suitable for packages 10 that are configured for use in the freezer, e.g., temperatures below about 20° F.
- FIG. 5 illustrates package 10 in use, retaining an item 150 therein.
- Item 150 is illustrated as a food item, particularly, a chicken leg.
- zipper 50 is opened, if necessary, by unmating, unsealing, etc.
- first and second zipper profiles 52 , 54 are spread sufficiently far to place item 150 through the mouth and between panels 12 , 14 .
- Item 150 should preferably be positioned between bottom edge 15 and venting feature 30 .
- Package 10 may be made by generally any suitable process.
- package 10 may be made by a horizontal process (e.g., where the film forming side surrounding wall 11 moves in a generally horizontal direction) or a vertical process (e.g., where the film forming surrounding wall 11 moves in a generally vertical direction).
- Vents 100 will generally be present in surrounding wall 11 (e.g., one or both of side panels 12 , 14 ) at the beginning of the process. Venting tape 35 will typically be applied over vents 100 prior to forming edges 15 , 16 , 18 , and may be present at the beginning of the package-making process.
- any or all of edges 15 , 16 , 18 may be folds or seals between side panels 12 , 14 .
- zipper profiles 52 , 54 may be attached to side panels 12 , 14 before or after bottom edge 15 is formed.

- This application claims the benefit of U.S. Provisional Application Ser. No. 60/735,780, filed on Nov. 12, 2005, which is incorporated herein by reference in its entirety.
- This disclosure relates to polymeric packages, and, in particular, to packages having a resealable closure arrangement and a venting feature, and methods of manufacturing and using the packages.
- Flexible polymeric packages may be used to hold a variety of products. Examples of such products include a variety of edible food products such as cheese, meat, crackers, granular sugar, powdered sugar, flour, salt, and baking soda, and non-food products such as laundry detergent, sand, medical supplies, and other products. Resealable packages are convenient because they can be closed and resealed after opening to contain the enclosed contents. Resealable packages are also advantageous in that they extend the life of food products because they can be opened and closed (resealed) multiple times. Resealable polymeric packages are used in environments that include the refrigerator, freezer, and at room conditions.
- The present disclosure is directed to reclosable packages having a zipper closure. The packages include a venting feature that allows flow of fluid, such as air, form the interior of the packages to the outside environment.

- Referring now to the figures, a package according to the present disclosure is illustrated in
FIGS. 1 and 1 A. Package 10 has afirst side panel 12 and an opposite second side panel 14 that are connected atside edges side edge 15 can be referred to as abottom edge 15.Side panels 12, 14 are flexible sheets, typically polymeric film. Examples of suitable polymeric films forpanels 12, 14 are well known, and include polyethylene, polypropylene, and the like. Laminated materials may also be used, which can include, but are not limited to, low density polyethylene (LDPE) and nylon or LDPE and polypropylene. -
Side panels 12, 14 andside edges wall 11 having an interior 20 therebetween. Interior 20 is configured for receiving item(s), for example a food item, for storage withinpackage 10. - As provided above,
side panels 12, 14 meet atbottom edge 15 andside edges edges FIG. 1A ,bottom edge 15 is a fold betweenside panel 12 and side panel 14; that is, a sheet of material has been folded to formpanels 12, 14 andbottom edge 15. Typically, in constructions withbottom edge 15 being a fold,side edges side panels 12, 14 are sealed to one another, for example by heat sealing. In other embodiments,side edge 16 is a folded edge andbottom edge 15 andside edge 18 are sealed. In yet another embodiment, bothside edges bottom edge 15 is sealed. Still further, embodiments ofpackage 10 could have each ofedges package 10. - Additionally, other configurations of surrounding
wall 11 could be used. For example, surroundingwall 11 may include side gussets or gussets inpanels 12, 14 to provide increased volume to interior 20. Also for example, surroundingwall 11 may have nodiscernible side panels 12, 14, but rather, could be a tubular bag-shaped element. Various other configurations of surroundingwalls 11 are known and are suitable for packages in accordance with the principles of this disclosure. - Returning to
FIG. 1 ,package 10 has atop end 17, which is the side ofpackage 10opposite bottom edge 15. Attop end 17, aresealable zipper 50 is present. Zipper 50 is present across a mouth ofpackage 10 that provides access to interior 20. Referring toFIG. 1A ,zipper closure 50 hasfirst zipper profile 52 having afirst profile member 56 and asecond zipper profile 54 having asecond profile member 58; first andsecond zipper profiles second zipper profiles zipper profiles - In the embodiment illustrated,
first zipper profile 52 is connected tofirst side panel 12 andsecond zipper profile 54 is connected to second side panel 14.Zipper profiles respective side panel 12, 14 or could be attached thereto, for example, by a heat seal or adhesive. Zippers 50,profiles profile members - Although not illustrated in the figures,
zipper closure 50 may be opened and closed by a slider element, as is well known; see for example, U.S. Pat. Nos. 6,679,027; Des. 480,988; Des. 479,467, and 6,450,686, each of which is incorporated herein by reference, for examples of suitable slider elements. - Still referring to
FIGS. 1 and 1 A,package 10 includes a venting structure orfeature 30, positioned in and/or on surroundingwall 11, e.g., in and/or on at least one ofside panels 12, 14, to allow escape of air from interior 20 to the exterior ofpackage 10. If present in and/or on at least one ofside panels 12, 14, ventingfeature 30 may extend fromside edge 16 toside edge 18, or may end short of either or bothedges - In the illustrated embodiment, venting
feature 30 includes a ventingtape 35 positioned over anarea 13 of side panel 14 having fluid passageways orvents 100 therethrough. To facilitate understanding of ventingfeature 30,FIG. 2 illustrates a portion of ventingtape 35 removed fromarea 13, thus exposingvents 100 in side panel 14. Ventingtape 35 is attached to side panel 14 in a manner allowingfluid passages 40 betweentape 35 and side panel 14. Ventingfeature 30, specifically ventingtape 35 and vents 100, provides a path for fluid flow from interior 20 ofpackage 10 to the exterior ofpackage 10. The fluid to pass through ventingfeature 30 can be either or both gaseous or liquid. In most uses ofpackage 10, the fluid passing through ventingfeature 30 will be air with some entrained moisture. -
Vents 100 inarea 13 may be any suitable shape or size, although the vents will generally be less than about 5 mm in their largest dimension, often less than about 3 mm. Three alternate configurations forvents 100 are illustrated inFIG. 3 . A first embodiment forvents 100 is crosses 110. In this configuration, no material from side panel 14 is removed; rather, side panel 14 is merely cut, slit, punched or otherwise ruptured to allow air to flow throughcrosses 110. A second embodiment forvents 100 isflaps 120, which are illustrated as arcuate or concave flaps inFIG. 3 . In this configuration, no material from side panel 14 is removed; rather, side panel 14 is merely cut, slit, punched or otherwise ruptured to define a flap that allows more air to flow therethrough than throughcrosses 110. A third embodiment forvents 100 ispolygonal apertures 130, which are illustrated as ovals or ellipses. In this configuration, material is removed from side panel 14 to form a void in side panel 14. Other polygons, such as circles, rectangles, triangles, etc. could be used. -
FIG. 4 illustrates an enlarged view of ventingtape 35, showingpassages 40 intermittently spaced between attachment regions 45 (i.e., regions where ventingtape 35 is attached to side panel 14, such as by the application of heat and pressure). Eachpassage 40 is positioned between twoadjacent attachment regions 45. In the particular embodiment shown,attachment regions 45 extend at least along the edges of ventingtape 35 and preferably provide sufficient volume therebetween for fluid flow. Adherence of ventingtape 35 to side panel 14 may be facilitated by adhesive inattachment regions 45; however, it is preferred not to have adhesive across the entire surface of ventingtape 35, as it will inhibit air flow.FIG. 4 illustratesfluid flow 60 throughpassages 40. - Venting
feature 30 allows fluid, e.g., air, to be expelled from interior 20 whilezipper closure 50 is sealed. The combination ofvents 100 in surroundingwall 11, (e.g., in side panel 14) and ventingtape 35, particularlypassages 40, control the rate of fluid flow from interior 20. It is understood that the flow throughvents 100 andpassages 40 can be modified by altering the characteristic, e.g., the dimensions, shaped, spacing, etc. ofvents 100 and/orpassages 40. - In the illustrated embodiment, venting
tape 35 is positioned on an exterior surface of side panel 14; it is understood that ventingtape 35 could alternately be positioned on the interior surface ofarea 13. It is believed that when ventingtape 35 is positioned on the exterior of side panel 14, air can easily pass out via ventingfeature 30 when pressure is applied, but air movement into interior 20 is difficult, which reduces the ingress of contaminants from outside ofpackage 10. It is also believed that when ventingtape 35 is positioned on the exterior of side panel 14, air can easily pass out from interior 20 via ventingfeature 30 when pressure is applied, but the flow of liquid is restricted. - Various specific details of
package 10 have been described. It is understood, however, that the previous descriptions are not limiting to features ofpackage 10, and alternate materials, constructions, and the like could be used to provide a package according to the present invention. For example,package 10 could optionally include a sealant stripe, such as a peal seal, which can be sealed, readily opened, and resealed, on an interior surface of surroundingwall 11, such aspanels 12, 14, in close proximity tozipper closure 50. Examples of peal seals include those described in U.S. Pat. Nos. 6,290,393; 6,210,038, and 6,131, 248, each of which is incorporated herein by reference. Such a seal could be used to decrease the possibility of leakage through the mouth ofpackage 10. Additionally or alternately,package 10 could include a textured stand-off area in surroundingwall 11, such as in one or both ofpanel 12, 14. Such a textured stand-off area is particularly suitable forpackages 10 that are configured for use in the freezer, e.g., temperatures below about 20° F. -
FIG. 5 illustratespackage 10 in use, retaining anitem 150 therein.Item 150 is illustrated as a food item, particularly, a chicken leg. To placeitem 150 inpackage 10, the general following procedure is followed:zipper 50 is opened, if necessary, by unmating, unsealing, etc. first and second zipper profiles 52, 54.Side panels 12, 14 are spread sufficiently far to placeitem 150 through the mouth and betweenpanels 12, 14.Item 150 should preferably be positioned betweenbottom edge 15 and ventingfeature 30. - After positioning
item 150 inpackage 10, it is optional to push or otherwise urge air present inpackage 10 out via unsealedzipper 50.Zipper 50 is sealed, providing a seal acrosspackage 10. When pressure is applied to package 10 in an area, such asarea 25 betweenbottom edge 15 andzipper 50, for example by the application of manual pressure by auser 170, at least some of the air remaining in interior 20 ofpackage 10 is pushed through ventingfeature 30 and out from interior 20 ofpackage 10. In particular, air passes throughvents 100 and then throughpassages 40. -
Package 10 may be made by generally any suitable process. For example,package 10 may be made by a horizontal process (e.g., where the film formingside surrounding wall 11 moves in a generally horizontal direction) or a vertical process (e.g., where the film forming surroundingwall 11 moves in a generally vertical direction).Vents 100 will generally be present in surrounding wall 11 (e.g., one or both ofside panels 12, 14) at the beginning of the process. Ventingtape 35 will typically be applied overvents 100 prior to formingedges edges side panels 12, 14. If not integral withside panels 12, 14, zipper profiles 52, 54 may be attached toside panels 12, 14 before or afterbottom edge 15 is formed. Similarly, a slider device (if present) may be applied tozipper profiles side panels 12, 14. - The above specification and examples are believed to provide a complete description of the manufacture and use of particular embodiments of the invention. Because many embodiments of the invention can be made without departing from the spirit and scope of the invention, the true scope and spirit of the invention reside in the broad meaning of the claims hereinafter appended.
