Abstract

A reclosable flexible package is described that includes an inner film layer, an outer film layer laminated to the inner film layer, and reclose region defined in a portion of package film layers. The reclose region includes pressure sensitive adhesive disposed between the inner and outer film layers. A number of cut lines are provided in the outer film layer in the reclose region, such that the user, by manipulating the package film layers at the reclose region, can reveal the underlying layer of pressure sensitive adhesive. Once the pressure sensitive adhesive of the reclose region is exposed, the action of the user can serve to adhere the pressure sensitive adhesive to itself and/or other portions of the film, such that the package is cinched in the area of the reclose region and maintains the remnants of the package contents within the reclosed package for later use.

First claim

What is claimed is:

1. A flexible package for holding a product, the flexible package comprising:
an inner film layer;
an outer film layer laminated to the inner film layer, said laminated film forming the flexible package, said flexible package being sealed and comprising an interior cavity with a product enclosed therein, and said inner film facing said cavity; and
a reclose region defined in a portion of the inner and outer film layers, the reclose region comprising pressure sensitive adhesive disposed between the inner and outer film layers and a plurality of cut lines defined in the outer film layer in the reclose region, said plurality of cut lines extending in the direction of a longitudinal axis of the package;
wherein the reclose region, pressure sensitive adhesive, and the plurality of cut lines extend around a full circumference or perimeter of the flexible package, and
wherein the plurality of cut lines are configured to expose at least one area of the pressure sensitive adhesive in the reclose region upon application of a twisting reclose force applied to the package at the reclose region, said twisting reclose force separating the outer film from the pressure sensitive adhesive at the plurality of cut lines of the reclose region, such that the at least one area of exposed pressure sensitive adhesive is adhereable to other parts of the flexible package to reclose the flexible package, thereby securing at least a portion of the product therein after the package has been opened.

2. The flexible package of claim 1 , wherein the product held within the flexible package comprises a candy bar.

3. The flexible package of claim 1 , wherein the reclose region comprises sections devoid of adhesive.

4. The flexible package of claim 1 , wherein the flexible package defines a first end and a second end, and wherein the reclose region is located approximately equidistantly from the first and second ends.

5. The flexible package of claim 1 , wherein the cut lines are straight lines.

6. The flexible package of claim 1 , wherein the cut lines are at a non-zero angle with respect to the longitudinal axis of the flexible package.

7. The flexible package of claim 1 , wherein the cut lines are spaced approximately ⅛-inch to approximately ¼-inch apart in the reclose region.

8. A method of manufacturing a flexible package for holding a product, the method comprising:
laminating an outer film layer to an inner film layer; and
defining a reclose region in a portion of the inner and outer film layers, wherein the reclose region is formed by:
applying a pressure sensitive adhesive between the inner film layer and the outer film layer in the reclose region, and
defining a plurality of cut lines in the outer film layer of the reclose region, said plurality of cut lines extending in the direction of a longitudinal axis of the package;

wherein said laminated film forms the flexible package, said flexible package is sealed and comprises an interior cavity, and said inner film layer faces said interior cavity,
wherein a product is enclosed within said interior cavity,
wherein the reclose region, pressure sensitive adhesive, and the plurality of cut lines extend around a full circumference or perimeter of the flexible package, and
wherein upon application of a twisting reclose force to the package by a user, at least one area of pressure sensitive adhesive is exposed by separation of the outer film from the pressure sensitive adhesive at the plurality of cut lines of the reclose region, and said pressure sensitive adhesive is adhereable to other portions of the flexible package to reclose the flexible package, thereby maintaining at least a portion of the product therein after the package has been opened.

9. The method of claim 8 , wherein applying the pressure sensitive adhesive comprises flood coating the inner film layer with the pressure sensitive adhesive.

10. The method of claim 8 , wherein applying the pressure sensitive adhesive comprises pattern applying the pressure sensitive adhesive to the inner film layer.

11. The method of claim 8 further comprising sealing first and second ends of the inner and outer film layers, after the outer film layer is laminated to the inner film layer, to form the flexible package and secure the product therein.

12. The method of claim 8 , wherein defining cut lines in the outer film layer in the reclose region comprises laser scoring the cut lines in the outer film layer.

13. The method of claim 8 , wherein defining cut lines in the outer film layer in the reclose region comprises defining straight cut lines in the outer film layer.

14. The method of claim 8 , wherein defining cut lines in the outer film layer in the reclose region comprises defining the cut lines at a non-zero angle with respect to the longitudinal axis of the flexible package.

15. The method of claim 8 , wherein defining cut lines in the outer film layer in the reclose region comprises spacing the cut lines to be approximately ⅛-inch to approximately ¼-inch apart in the reclose region.
