Abstract

A pouch and method of making a pouch having configured to displace stress from an inner peripheral edge of a seal is provided. The pouch includes a pouch body sealed along its peripheral edge so as to define a panel. The pouch includes an outer strip. The outer strip is mounted to both sides of the panel, and a distal edge portion of both sides of the strip extends inwardly towards the center of the pouch body so as to extend beyond the inner peripheral edge of the panel. The side edges of the strip overlap the inner peripheral edge of the seal.

First claim

I claim:

1. A pouch; the pouch comprising:
a pouch body defined by a pair of sheets sealed together so as to form a panel having a first side opposite a second side, and an inner peripheral edge opposite an outer peripheral edge;
an outer layer formed of a sheet of material and folded over the outer peripheral edge of the panel, wherein a first portion of the outer layer mounted is mounted onto the first side of the panel and a second portion of the outer layer is mounted onto the second side of the panel, wherein the first portion of the outer layer extends away from the outer peripheral edge of the panel so as to place a first distal edge of the first portion beyond the inner peripheral edge of the panel and closer towards a center of the pouch body relative to the inner peripheral edge of the panel, and wherein the second portion of the outer layer extends away from the outer peripheral edge of the panel and beyond the inner peripheral edge of the panel towards the center of the pouch body so as to place a second distal edge of the second portion closer towards the center of the pouch body relative to the inner peripheral edge, the outer layer configured to displace stress from an inner peripheral edge of a seal; and
a pair of air channels, the air channels are disposed between the inner peripheral edge and the outer peripheral edge on opposite sides of the pouch body.

2. The pouch of claim 1 , wherein the panel defines a peripheral edge of the pouch body.

3. The pouch of claim 1 , further including a fitment.

4. The pouch of claim 1 , wherein the outer layer is a strip of material, the strip has a width defined as the distance between a first outer edge and a second outer edge of the strip, wherein the first outer edge mounted on top of a front of the pouch and the second outer edge is mounted on top of a back of the pouch.

5. The pouch of claim 4 , wherein the strip is formed of a pliable material providing flexibility generally commensurate with the flexibility of the pouch body.

6. The pouch of claim 4 , wherein the strip overlaps the inner peripheral edge of the panel.

7. The pouch of claim 1 , wherein the outer layer is mounted over both the front and back of the pouch body so as to form a fold.

8. The pouch of claim 1 , wherein each of the pair of air channels bisect an axial length of the panel, dividing the panel into halves of the panel.
