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 first and second ends and the flexible package comprises an interior cavity into which a product is placed, and wherein the inner film layer faces the interior 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 within the reclose region, wherein the plurality of cut lines extend longitudinally between the first and second ends,
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 has a longitudinal direction, and
opposite longitudinal ends of each of the plurality of strips are continuous with the outer film layer,
wherein the package is in a reclosed configuration, the reclosed configuration comprising,
a portion of at least one of the plurality of strips, between its longitudinal ends, is separated from the pressure sensitive adhesive, and
at least a first region of the pressure sensitive adhesive is adhered to at least a second region of the pressure sensitive adhesive, and
the opposite longitudinal ends of the at least one of the plurality of strips remain continuous with the outer film layer.

2. The flexible package of claim 1 , wherein the reclosed configuration comprises,
each of the plurality strips is separated from the pressure sensitive adhesive to form a plurality of exposed regions of the pressure sensitive adhesive and at least a portion of a first exposed region of the pressure sensitive adhesive is adhered to at least a portion of a second exposed region of the pressure sensitive adhesive, and the opposite longitudinal ends of each of the plurality of strips remain continuous with the outer film layer.

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 flexible package comprises a sleeve, a bar wrap, or a slug-type package.

6. The flexible package of claim 1 , wherein the flexible package comprises a plurality of reclose regions located between the first and second ends.

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

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

9. 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.

10. 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.

11. The flexible package of claim 5 , wherein the plurality of cut lines extend around a full circumference or perimeter of the flexible package.

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 first and second ends and the flexible package comprises an interior cavity into which a product is placed, and wherein the inner film layer faces the interior 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 the plurality of cut lines extend longitudinally between the first and second ends,
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 has a longitudinal direction, and
opposite longitudinal ends of each of the plurality of strips are continuous with the outer film layer,
wherein the package is in a reclosed configuration, the reclosed configuration comprising,
a portion of at least one of the plurality of strips, between the longitudinal ends of the at least one plurality of strips, is separated from the pressure sensitive adhesive, forming an exposed region of the pressure sensitive adhesive; and
at least a portion of the exposed region of the pressure sensitive adhesive is adhered to a portion of the outer film layer, and
the opposite longitudinal ends of the at least one of the plurality of strips remain continuous with 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 flexible package comprises a sleeve, a bar wrap, or a slug-type package.

17. 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 first and second ends and the flexible package comprises an interior cavity into which a product is 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 the plurality of cut lines extend longitudinally between the first and second ends,
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 has a longitudinal direction, and opposite longitudinal ends of each of the plurality of strips are uncut and continuous with the outer film layer,
wherein the package is in a reclosed configuration, the reclosed configuration comprising,
a portion of at least one of the plurality of strips, between the longitudinal ends of the at least one of the plurality of strips is separated from the pressure sensitive adhesive, and
at least a first region of the pressure sensitive adhesive is adhered to at least a second region of the pressure sensitive adhesive or to a portion of the outer film layer, and
the opposite longitudinal ends of the at least one of the plurality of strips remain continuous with the outer film.
