Abstract

The method including providing a sheet of material in the form of a strip, first folding the sheet of material onto itself to form a first package face and a second package face that oppose each other, a first end portion and a second end portion of the sheet of material extending from the first package face, sealing the sheet of material along opposed longitudinal edges of the sheet of material, fixing the first end portion and the second end portion to each other to form a sealing flap, first defining an opening cut in the sealing flap, the opening cut being defined by both the first end portion and the second end portion, and connecting the sealing flap to the first package face to form the assembled package, the opening cut not being visible or directly accessible on the assembled package.

First claim

The invention claimed is:

1. A method of forming an assembled package, comprising:
providing a sheet of material in the form of a strip;
fixing a first end portion and a second end portion of the sheet of material to each other to form a sealing flap, a remainder of the sheet of material remaining connected to the sealing flap;
first folding the remainder of the sheet of material onto itself to form a first package face and a second package face that oppose each other, the sealing flap extending from the first package face;
sealing the sheet of material along opposed longitudinal edges of the sheet of material;
first defining an opening cut in the sealing flap, the opening cut being defined by both the first end portion and the second end portion; and
connecting the sealing flap to the first package face to form the assembled package, the opening cut not being visible or directly accessible on the assembled package.

2. The method of claim 1 , further comprising:
second folding a first fold line in the sealing flap, the first fold line traversing across a width of the sealing flap and dividing the sealing flap into a first portion and a second portion, the first portion defining the opening cut, the opening cut running along a longitudinal length of the sealing flap.

3. The method of claim 2 , wherein the connecting connects the sealing flap so that the first portion is sealed between the second portion and the first package face.

4. The method of claim 2 , wherein the first folding folds the remainder of the sheet of material to form a second fold line that divides the sealing flap from the first package face, the second fold line traversing across the width of the sealing flap on a proximal end of the sealing flap.

5. The method of claim 4 , further comprising:
second defining an incomplete weakening line between the opening cut and the first package face, the incomplete weakening line being configured to redirect an opening motion of the assembled package that is initiated at the opening cut to ensure that the first package face is not damaged during an opening of the assembled package.

6. The method of claim 5 , wherein
the first defining defines the opening cut to exist along a first line, and
the second defining defines the incomplete weakening line to exist along a second line, the first line being substantially perpendicular to the second line.

7. The method of claim 4 , further comprising:
second defining an incomplete weakening line between the opening cut and the first package face, the incomplete weakening line being configured to redirect an opening motion of the assembled package that is initiated at the opening cut to ensure that the first package face is not damaged during an opening of the assembled package, the opening motion being redirected by the incomplete weakening line from a longitudinal direction along the longitudinal length to a transversal direction.

8. The method of claim 1 , wherein the first folding folds the remainder of the sheet of material to form a first fold line that divides the sealing flap from the first package face, the first fold line traversing across a width of the sealing flap on a proximal end of the sealing flap.

9. The method of claim 1 , further comprising:
second folding a first fold line in the sealing flap, the first fold line traversing a width of the sealing flap and dividing the sealing flap into a first portion and a second portion, the first portion defining the opening cut, the first portion including a distal-most end of the sealing flap, the opening cut running along a longitudinal length of the sealing flap.

10. The method of claim 1 , further comprising:
second folding a first fold line in the sealing flap, the first fold line traversing a width of the sealing flap and dividing the sealing flap into a first portion and a second portion, the first portion defining the opening cut, the opening cut running along a longitudinal length of the sealing flap, the opening cut being between the first fold line and a distal-most end of the sealing flap, the first package face and the second package face substantially lying flat on each other.

11. The method of claim 1 , wherein the defining defines the opening cut so that the opening cut does not traverse through a distal-most end of the sealing flap.

12. The method of claim 1 , further comprising:
second defining an incomplete weakening line between the opening cut and the first package face, the incomplete weakening line being configured to redirect an opening motion of the assembled package that is initiated at the opening cut to ensure that the first package face is not damaged during an opening of the assembled package.

13. The method of claim 1 , further comprising:
second defining an incomplete weakening line between the opening cut and the first package face, the incomplete weakening line being configured to redirect an opening motion of the assembled package that is initiated at the opening cut to ensure that the first package face is not damaged during an opening of the assembled package, the opening motion being redirected by the incomplete weakening line from a longitudinal direction along a longitudinal length of the sealing flap to a transversal direction.

14. The method of claim 1 , wherein
the sealing seals the sheet of material with a first connection force, and
the connecting connects the sealing flap with a second connection force, the first connection force being stronger than the second connection force.

15. The method of claim 1 , wherein the first folding folds the remainder of the sheet of material such that the remainder of the sheet of material is subdivided into the first end portion, the second end portion, a center panel, a first side panel and a second side panel, the first side panel being between the center panel and the first end portion and the second side panel being between the center panel and the second end portion.

16. The method of claim 15 , wherein the first folding folds the remainder of the sheet of material such that the first side panel and the second side panel forms the first package face.

17. The method of claim 16 , wherein the first folding folds the remainder of the sheet of material such that the center panel forms the second package face.

18. The method of claim 1 , wherein the first defining defines the opening cut to run along a centerline of a longitudinal length of a portion of the sealing flap.

19. The method of claim 18 , wherein the first defining defines the opening cut to cause the sealing flap to be split into a first part and a second part, the first part and the second part being substantially equal in size.
