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 reclosable flexible package for holding a product, the flexible package comprising:
an inner film layer;
an outer film layer laminated to the inner film layer to form a laminate, wherein the laminate forms the flexible package having a length and first and second opposing ends and the flexible packaging comprises an interior cavity into which a product can be placed, and wherein the inner film layer faces the cavity; and
a reclose region defined in a portion of the laminate, the reclose region comprising pressure sensitive adhesive disposed between the inner and outer film layers and a plurality of cut fines defined in the outer film layer within the reclose region,
wherein a plurality of strips of the outer film layer are disposed between adjacent cut lines of the plurality of cut lines, each of the plurality of strips extends in a longitudinal direction toward the first and second opposing ends of the flexible package, and each of the plurality of strips having opposing longitudinal ends extending to the respective adjacent cut lines that define each strip, and the entirety of the opposing longitudinal ends of each strip are uncut and continuous with the outer film layer, and the plurality of cut lines extend around a full circumference or perimeter of the flexible package; and
wherein when the package is in a reclosed configuration, the opposing longitudinal ends of each strip remain uncut and continuous with the outer film layer and for a plurality of the strips, a portion of each strip between its opposing longitudinal ends is separated from the pressure sensitive adhesive and at least a first region of pressure sensitive adhesive is adhered to at least a second region of pressure sensitive adhesive.

2. The flexible package of claim 1 , wherein when the package is in a reclosed configuration, separation of each of the plurality strips from the pressure sensitive adhesive forms a plurality of exposed regions of pressure sensitive adhesive and at least a portion of a first exposed region of pressure sensitive adhesive is adhered to at least a portion of a second exposed region of pressure sensitive adhesive.

3. The flexible package of claim 1 , wherein the plurality of cut lines are parallel to one another.

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

5. The flexible package of claim 1 , wherein the reclose region is located between the first and second opposing ends.

6. The flexible package of claim 5 , wherein the flexible package comprises a sleeve, a bar wrap, or a slug-type package.

7. The flexible package of claim 5 , wherein the flexible package comprises a plurality of reclose regions located between the first and second opposing ends.

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

9. The flexible package of claim 1 , wherein the plurality of cut lines are parallel with a longitudinal axis of the package.

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

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

12. A reclosable flexible package for holding a product, the flexible package comprising:
an inner film layer;
an outer film layer laminated to the inner film layer to form a laminate, wherein the laminate forms the flexible package having a length and first and second opposing ends, and the flexible package comprises an interior cavity into which a product can be placed, and wherein the inner film layer faces the cavity; and
a reclose region defined in a portion of the laminate, 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,
wherein a plurality of strips of the outer film layer are disposed between adjacent cut lines of the plurality of cut lines, each of the plurality of strips extends in a longitudinal direction toward the first and second opposing ends of the flexible package and each of the plurality of strips having opposing longitudinal ends extending to the respective adjacent cut lines that define each strip, and the entirety of the opposing longitudinal ends of each strip are uncut and continuous with the outer film layer, and the plurality of cut lines extend around a full circumference or perimeter of the flexible package; and
wherein when the package is in a reclosed configuration,
the opposing longitudinal ends of each strip remain uncut and continuous with the outer film layer;
for a plurality of the strips, a portion of each strip between its opposing longitudinal ends is separated from the pressure sensitive adhesive, forming an exposed region of pressure sensitive adhesive; and
at least a portion of the exposed region of pressure sensitive adhesive is adhered to a portion of the outer film layer.

13. The flexible package of claim 12 , wherein the cut lines are wavy lines.

14. The flexible package of claim 12 , wherein the cut lines are curved lines.

15. The flexible package of claim 12 , wherein the reclose region comprises sections devoid of adhesive.

16. The flexible package of claim 12 , wherein the reclose region is located between the first and second opposing ends.

17. The flexible package of claim 16 , wherein the flexible package comprises a sleeve, a bar wrap, or a slug-type package.

18. A reclosable flexible package for holding a product, the flexible package comprising:
an inner film layer;
an outer film layer laminated to the inner film layer to form a laminate, wherein the laminate forms the flexible package having a length and first and second opposing ends and the flexible packaging comprises an interior cavity into which a product can be placed, and wherein the inner film layer faces the cavity; and
a reclose region defined in a portion of the laminate, 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,
wherein a plurality of strips of the outer film layer are disposed between adjacent cut lines of the plurality of cut lines, each of the plurality of strips extends in a longitudinal direction toward the first and second opposing ends of the flexible package and each of the plurality of strips having longitudinal ends extending to the respective adjacent cut lines that define each strip, and the entirety of the opposing longitudinal ends of each strip remain uncut and continuous with the outer film layer, and the plurality of cut lines extend around a full circumference or perimeter of the flexible package;
wherein when the package is in a sealed or open, but not reclosed configuration, each strip has a longitudinal direction and both longitudinal ends of each strip remain uncut and continuous with the outer film layer; and
wherein when the package is in a reclosed configuration, the opposing longitudinal ends of each strip remain uncut and continuous with the outer film layer and for a plurality of the strips, a portion of each strip between its opposing longitudinal ends is separated from the pressure sensitive adhesive and at least a first region of pressure sensitive adhesive is adhered to at least a second region of pressure sensitive adhesive or a portion of the outer film layer.
