Abstract

A flexible walled package formed from a multiple layer laminate and having an external recloseable pocket for holding a scoop or other item is provided. The pocket has a back panel formed from part of an inner layer and a front panel formed from part of a scored outer layer. Outside the perimeter of the pocket the inner layer and the outer layer are adhered together with permanent adhesive. Inside the pocket perimeter the inner layer and the outer layer may be adhered together with pressure sensitive adhesive to close the pocket.

First claim

The invention claimed is:

1. A package comprising a flexible wall formed from a laminate, the laminate comprising:
an inner layer; and
an outer layer, the outer layer comprising a fixed portion permanently attached to the inner layer by permanent adhesive and an adhesive-free pocket-shaped area tangentially attached to the fixed portion along a perimeter, the adhesive-free pocket-shaped area having a top edge, the outer layer further comprising a score line substantially in registration with the top edge;
a portion of the inner layer and the pocket-shaped area of the outer layer forming an external pocket; the package further comprising
a pressure sensitive adhesive pattern applied only to a top marginal region located entirely within the adhesive free pocket shaped area just below and co-extensive with the top edge, a remaining area of the adhesive free pocket shaped area being free from adhesive; wherein
the external pocket has a closed position in which the inner layer and the outer layer are adhered together along the top marginal region and an open position in which the outer layer is at least partially disengaged from the inner layer along the top marginal region.

2. The package of claim 1 further comprising an article disposed inside the package and configured to fit at least partially within an interior defined by the external pocket.

3. The package of claim 2 wherein the package is configured to hold powder and granular product and the article is a scoop.

4. The package of claim 1 wherein the flexible wall is a gusset panel.

5. The package of claim 1 wherein:
the adhesive-free area includes a pull tab shaped area located at the top edge; and
the score line forms a pull tab that overlies the pull tab shaped area.

6. The package of claim 1 wherein:
the score line includes curved end portions.

7. A package comprising:
an inner layer;
an outer layer coextensive with the inner layer, the outer layer comprising an adhesive area, a pocket shaped area and a top marginal region located within the pocket shaped area, the pocket shaped area having a perimeter, the perimeter having a top edge;
a permanent adhesive layer disposed between the inner layer and the outer layer in an area that is coextensive with the adhesive area but not the pocket shaped area;
a pressure sensitive adhesive disposed between outer layer and the inner layer only in a top marginal region located entirely within the pocket shaped area just below and co-extensive with the top edge, a remaining area of the adhesive free pocket shaped area being free from adhesive; and
a score line extending through the outer layer substantially in registration with the top edge; wherein
the inner layer and the pocket shaped area of the outer layer form a recloseable pocket.

8. The package of claim 7 wherein the outer layer and the inner layer are adhered to each other by the permanent adhesive along the entire perimeter except for the top edge.

9. The package of claim 8 wherein the top edge is substantially linear.

10. The package of claim 7 wherein the top marginal region is adjacent the top edge.

11. The package of claim 7 further comprising an article disposed inside the package and configured to fit at least partially within an interior defined by the pocket.

12. The package of claim 11 wherein the package is configured to hold powder and granular product and the article is a scoop.

13. The package of claim 7 wherein:
the pocket shaped area includes a pull tab shaped area located at the top edge; and
the score line forms a pull tab that overlies the pull tab shaped area.

14. The package of claim 13 wherein:
the score line includes curved end portions.

15. A method of making a laminate having an external pocket, the method comprising the steps of:
pattern applying a permanent adhesive onto a first sheet of material but excluding the permanent adhesive from a pre-determined pocket shaped area, the pocket shaped area having a perimeter, the perimeter having a top edge;
pattern applying a pressure sensitive adhesive onto the first sheet of material in a predetermined pattern coinciding only with a top marginal region located entirely within the pocket shaped area and adjacent the top edge such that a remaining area of the adhesive free pocket shaped area is free from adhesive;
adhesively joining the first sheet of material to a second sheet of material via the adhesives; and
scoring one of the sheets of material along a score line substantially in registration with the top edge of the pocket shaped area.

16. The method of claim 15 wherein the first sheet of material is an outer layer of flexible material and the second sheet is an inner layer of flexible material.

17. The method of claim 16 wherein during the scoring step the outer layer is scored and the score line extends only through the thickness of the outer layer.

18. The method of claim 17 wherein the score line is formed with a laser.

19. The method of claim 17 wherein the score line is formed by die cutting.
