Abstract

The present invention relates to a flexible pouch (1) having a wider opening (2) allowing to get a better access of the content of the pouch (1). The perimeter (a) of the opening (2) of the flexible pouch (1) is greater than the perimeter (b) of its bottom (3). At least one of the lateral folding lines (5) of the flexible pouch (1) comprises a welding line (6) of a width (w). A part or all of the lateral welding lines (6) of the flexible pouch (1) have a width (w) which is not constant along its length. The invention also relates to a kit-of-part comprising the flexible pouch (1) according to the invention and a container (14) adapted to receive said flexible pouch (1).

First claim

The invention claimed is:

1. A flexible pouch comprising:
an opening with a first perimeter;
a bottom with a second perimeter, a ratio of the first perimeter over the second perimeter is from 1.1 to 1.25;
at least two side walls; and
at least two lateral folding lines, at least one of the at least two lateral folding lines comprising a lateral welding line, and the lateral welding line having a length and a first width near the bottom and a second width near the opening, the first width is greater than the second width.

2. The flexible pouch according to claim 1 , comprising two side walls, two lateral folding lines, and two lateral welding lines.

3. The flexible pouch according to claim 1 , comprising four side walls, four lateral folding lines, and four lateral welding lines.

4. The flexible pouch according to claim 1 , comprising four lateral welding lines that include the lateral welding line, each of the four lateral welding lines having the first width near the bottom and a second width near the opening, the first width is greater than the second width.

5. The flexible pouch according to claim 1 , wherein the lateral welding line is one of at least two lateral welding lines of the flexible pouch, each of the at least two lateral welding lines having the first width near the bottom and a second width near the opening, the first width is greater than the second width.

6. The flexible pouch according to claim 1 , comprising at least one lateral welding line having a width that varies regularly or irregularly along the length of the at least one lateral welding line.

7. The flexible pouch according to claim 1 , comprising at least one lateral welding line that has an interruption between the opening and the bottom at a distance from the opening.

8. The flexible pouch according to claim 1 , further comprising at least two shoulders at a distance from the opening.

9. The flexible pouch according to claim 1 , comprising four side walls, four lateral folding lines, four lateral welding lines, all of the four side walls, the four lateral folding lines, and the four lateral welding lines each having an interruption at a similar distance from the opening, and four shoulders located at the similar distance from the opening.

10. The flexible pouch according to claim 1 , wherein the opening is closed with a closing member.

11. The flexible pouch according to claim 1 , wherein the flexible pouch is a stand-up pouch.

12. The flexible pouch according to claim 1 , wherein the bottom comprises a member that improves stability of the flexible pouch.

13. The flexible pouch according to claim 1 , wherein the flexible pouch is manufactured by vertical form-fill-seal technology.

14. The flexible pouch according to claim 6 , wherein the width of the at least one lateral welding line decreases proportionally from the bottom to the opening.

15. The flexible pouch according to claim 10 , wherein the closing member is selected from the group consisting of a plurality of reclose strips, a sticker, and combinations thereof.

16. A kit comprising:
a flexible pouch comprising an opening with a first perimeter, a bottom with a second perimeter, at least two side walls, at least two lateral folding lines, at least one of the at least two lateral folding lines comprising a lateral welding line, a ratio of the first perimeter over the second perimeter is from 1.1 to 1.25, the lateral welding line having a length and a first width near the bottom and a second width near the opening, the first width greater than the second width; and
a container comprising a container base having a third perimeter, a container opening having a fourth perimeter, at least two container side walls, the container is adapted to receive the flexible pouch.

17. The kit according to claim 16 , wherein the container is adapted to receive the flexible pouch even when the flexible pouch is open.

18. The kit according to claim 16 , wherein the third perimeter of the base of the container is smaller than the fourth perimeter of the opening of the container.

19. The kit according to claim 16 , wherein the container opening can be closed or hermetically closed with a lid.

20. A method for storing and/or dispensing dried food products, the method comprising storing the dried food products in a flexible pouch, the flexible pouch comprising an opening with a first perimeter, a bottom with a second perimeter, at least two side walls, at least two lateral folding lines, at least one of the at least two lateral folding lines comprising a lateral welding line, a ratio of the first perimeter over the second perimeter is from 1.1 to 1.25, the lateral welding line having a length and a first width near the bottom and a second width near the opening, the first width greater than the second width defining a conical shape of the flexible pouch when the flexible pouch is open.

21. A method for providing access to a product stored in a flexible pouch, the method comprising storing the product in the flexible pouch, the flexible pouch comprising an opening with a first perimeter, a bottom with a second perimeter, at least two side walls, at least two lateral folding lines, at least one of the at least two lateral folding lines comprising a lateral welding line, a ratio of the first perimeter over the second perimeter is in a range from 1.1 to 1.25, the lateral welding line having a length and a first width near the bottom and a second width near the opening, the first width greater than the second width.
