Abstract

Embodiments include a package for containing and dispensing a product. The package includes first and second layers; a product seal zone where the first layer is joined to the second layer, the product seal zone having an inner perimeter that defines an unsealed pouch area for containing the product and an outer perimeter; and a header zone adjacent to the outer perimeter of the product seal zone. The header zone includes a first tab; a second tab; a first tab-cut in the first layer within an unsealed portion of the header zone; and a second tab-cut in the second layer within the unsealed portion of the header zone. Other embodiments are also included herein.

First claim

What is claimed is:

1. A package for containing and dispensing a product, comprising:
a first layer;
a second layer;
a product seal zone where the first layer is joined to the second layer by a seal, the product seal zone having an inner perimeter and an outer perimeter, wherein the inner perimeter defines a single unsealed pouch area for containing the product; and
a header zone adjacent to the outer perimeter of the product seal zone, wherein the header zone comprises:
a first tab;
a second tab;
a first tab-cut in the first layer within an unsealed portion of the header zone; and
a second tab-cut in the second layer within the unsealed portion of the header zone;
wherein the first tab-cut does not intersect the second tab-cut;
wherein the package defines a void between the first tab and the second tab;
wherein the first tab-cut terminates at an edge of the package that defines a portion of the void; and
wherein the second tab-cut terminates at the edge of the package that defines the portion of the void.

2. The package of claim 1 , wherein the first tab-cut and the second tab-cut are both located in an unsealed area of the package.

3. The package of claim 1 , wherein the first tab comprises a first tab seal zone in which the first layer is joined to the second layer, and wherein the second tab comprises a second tab seal zone in which the first layer is joined to the second layer.

4. The package of claim 3 , wherein an unsealed portion between the product seal zone and the first tab seal zone and the second tab seal zone extends across the package from one edge of a package perimeter to an opposite edge of the package perimeter.

5. The package of claim 1 , wherein the first tab-cut extends from the void across a portion of the package to the perimeter of the package, and the second tab-cut extends from the void across a portion of the package to the perimeter of the package.

6. The package of claim 5 , wherein the first tab-cut extends to a first side edge of the package and the second tab-cut extends to a second side edge of the package opposite from the first side edge.

7. The package of claim 1 , wherein the first tab comprises a first tactile feature and the second tab comprises a second tactile feature, wherein each of the tactile features is selected from a group consisting of: an aperture, one or more slits, grooves, bumps, and recesses.

8. The package of claim 1 , wherein the first tab comprises a first tactile feature and the second tab comprises a second tactile feature, wherein each of the tactile features defines an aperture and a dulling element along a portion of an aperture edge, and wherein the dulling element includes a folded portion of at least one of the first or second layer.

9. The package of claim 1 , wherein there is no cut in the second layer at a location corresponding to the first tab-cut on the first layer and there is no cut in the first layer at a location corresponding to the second tab-cut on the second layer.

10. The package of claim 1 , wherein the first tab-cut is not parallel with the second tab-cut.

11. The package of claim 1 , further comprising a first score in the first layer and a second score in the second layer, wherein the first score is parallel to the second score, and wherein the first score and the second score each extend from one end of the package to an opposite end of the package.

12. The package of claim 1 , wherein the product seal zone comprises a peel brake feature, wherein the product seal zone requires a user to apply more force to separate the first layer from the second layer at the peel brake feature than along a portion of the product seal zone adjacent to the peel brake feature.

13. The package of claim 12 , wherein the peel brake feature comprises a peel interrupt feature that impedes the separation of the first layer from the second layer, wherein the peel interrupt feature comprises at least one from the group comprising:
a crimp,
a cut in at least one of the first layer and the second layer,
an edge-cut in at least one of the first layer and the second layer that starts at the outer perimeter,
a notch,
a weld, and
an ultrasonic weld.

14. The package of claim 1 , wherein the product seal zone has a variable width that varies along a side edge of the package, the variable width comprising a first width at a first portion of the product seal zone and a second width greater than the first width at a second portion of the product seal zone, wherein the first portion of the product seal zone is closer to the header zone than the second portion, whereby the variable width along the side edge requires a user to apply increased force to separate the first layer from the second layer at an end of the package opposite the header zone.

15. The package of claim 1 , wherein a portion of the product seal zone that is adjacent to a top seal zone requires less force to separate the first layer from the second layer than a portion of the product seal zone that is on the opposite end of the package from the header zone.
