Abstract

A scored package is described. The first panel of the package comprises a multilayer film with an exterior layer having a nonlinear first score Sine and an interior layer having a linear second score line. The first score line and the second score fine are positioned non-parallel in a plane of the package such that the first score line intersects the second score line to form an opening in the package at the second score line when the exterior layer and the interior layer are separated. Separation of the exterior layer and the interior layer also forms an adhesive-free pour spout in the separated exterior layer. Various embodiments of various package configurations, score line configurations, multilayer film structures and methods of manufacturing are also described.

First claim

What is claimed is as follows:

1. A package comprising a first panel, a second panel, a first edge connecting the first panel and the second panel, a second edge connecting the first panel and the second panel, a third edge connecting the first panel and the second panel and a fourth edge connecting the first panel and the second panel;
wherein the first panel comprises a multilayer film comprising
an exterior layer having a nonlinear first score line having a flat end and a second end, wherein each of the first end and the second end is positioned in the first panel and wherein the exterior layer is adjacent to each of the first edge, the second edge, the third edge, and the fourth edge of the first and second panels,
an interior layer having a linear second score line having a first point spaced apart from a second point, and
a first region defined by an area between the first score line and the second score line,

wherein the exterior layer and the interior layer are adapted to be separated in the first region, wherein the first score line and the second score line are positioned non-parallel in a plane of the package such that the first score line intersects the second score line at each of the first point and the second point to form an opening in the package at the second score line when the exterior layer and the interior layer are separated and wherein the exterior layer forms an adhesive-free portion that remains hingedly and integrally attached to a remainder of the exterior layer at the opening, wherein the adhesive-free portion is positioned between the opening and the third edge when the exterior layer and the interior layer are separated; and
wherein the second panel is a flexible film and wherein the third edge comprises:
a) a gusset member formed or plowed in a fold between and connecting the first panel and the second panel, or
b) a gusset member inserted and sealed between and connecting the first panel and the second panel.

2. The package of claim 1 wherein the first end of the first score line is positioned adjacent to the first edge, the second edge, the third edge, or the fourth edge.

3. The package of claim 1 wherein the second end of the first score line is positioned adjacent to the first edge, the second edge, third edge or the fourth edge.

4. The package of claim 1 wherein the first end of the first score line is positioned non-adjacent to the first edge, the second edge, the third edge or the fourth edge.

5. The package of claim 1 wherein the second end of the first score line is positioned non-adjacent to the first edge, the second edge, third edge or the fourth edge.

6. The package of claim 1 wherein the first panel multilayer film further comprises an intermediate layer positioned between the exterior layer and the interior layer.

7. The package of claim 6 wherein the intermediate layer comprises a release agent positioned between the exterior layer and the interior layer in the first region.

8. The package of claim 7 wherein the first panel multilayer film further comprises a pattern connecting layer positioned between the release agent and the interior layer in the first region, wherein the pattern connecting layer remains attached to the interior layer when the exterior layer and the interior layer are separated and wherein the exterior layer and the interior layer are adapted to be reattached in the first region.

9. The package of claim 1 wherein the first panel multilayer film further comprises a flood connecting layer positioned between the exterior layer and the interior layer.

10. The package of claim 1 wherein the third edge comprises a gusset member and the package is a stand-up pouch.

11. The package of claim 1 where in each of the first edge, the second edge and the fourth edge comprises a heat seal.

12. The package of claim 1 wherein the first score line has a shape that is arcuate, rectilinear, angled with lines of even length or lines of uneven length, inverted v-shaped, w-shaped or inverted w-shaped.

13. The package of claim 1 wherein the adhesive-free portion is a pour spout.

14. The package of claim 13 wherein the pour spout is non-folded.

15. A package comprising a first panel, a second panel, a firs edge connecting the first panel and the second panel, a second edge connecting the first panel and the second panel, a third edge connecting the first panel and the second panel and a fourth edge connecting the first panel and the second panel;
wherein the first panel comprises a multilayer film comprising
an exterior layer having a nonlinear first score line having a first end and a second end, wherein each of the first end and the second end is positioned in the first panel,
an interior layer having a linear second score line having a first point spaced apart from a second point,
an intermediate layer comprising a release agent positioned between the exterior layer and the interior layer in a first region between the first score line and the second score line,
a pattern connecting layer positioned between the intermediate layer and the interior layer in the first region, and
a flood connecting layer positioned between the pattern connecting layer and the interior layer in the first region,

wherein the exterior layer and the interior layer are adapted to be separated in the first region, wherein the first score line and the second score line are positioned non-parallel in a plane of the package such that the first score line intersects the second score line at each of the first point and the second point to form an opening in the package at the second score line when the exterior layer and the interior layer are separated, wherein the exterior layer forms an adhesive-free portion that remains hingedly and integrally attached to a remainder of the exterior layer at the opening, wherein the adhesive-free portion is positioned between the opening and the third edge when the exterior layer and the interior layer are separated, wherein the pattern connecting layer remains attached to the interior layer when the exterior layer and the interior layer are separated and wherein the exterior layer and the interior layer are adapted to be reattached in the first region; and
wherein the second panel is a flexible film and wherein the third edge comprises:
a) a gusset member formed or plowed in a fold between and connecting the first panel and the second panel, or
b) a gusset member inserted and sealed between and connecting the t panel and the second panel.

16. The package of claim 15 wherein the first end of the first score line is positioned adjacent to the first edge, the second edge, the third edge or the fourth edge.

17. The package of claim 15 wherein the second end of the first core line is positioned adjacent to the first edge, the second edge, third edge or the fourth edge.

18. The package of claim 15 wherein the first end of the first score line is positioned non-adjacent to the first edge, the second edge, the third edge or the fourth edge.

19. The package of claim 15 wherein the second end of the first score line is positioned non-adjacent to the first edge, the second edge, third edge or the fourth edge.

20. The package of claim 15 wherein the third edge comprises a gusset member and the package is a stand-up pouch.

21. The package of claim 15 wherein each of the first edge, the second edge and the fourth edge comprises a heat seal.

22. The package of claim 15 wherein the first score line has a sha
