Benefits of technology

[0014] According to yet another aspect of the present invention, a pouch includes first and second opposing walls and an extruded pleat disposed in the first wall. The pleat extends laterally across the pouch between first and second side portions of the pouch. Further, the pleat is welded at first and second side portions of the pouch to the opposing pouch wall, thereby only allowing the pleat to expand along portions of the pouch that are not adjacent the first and second side portions of the pouch to expand the pouch in a direction transverse to an axis of the opposing walls.

Problems solved by technology

This necessitates the consumer purchasing multiple boxes of thermoplastic pouches for different items and can become very expensive and inconvenient for the consumer.

Embodiment Construction

[0022] Referring to FIG. 1, a reclosable pouch in the form of a thermoplastic storage bag 20 comprises first and second body portions 22, 24 joined to one another to form first and second bag walls 26, 28. The first and second bag walls 26, 28 are joined at first and second side portions 30, 32, respectively, and at a bottom portion 34. An opening 35 and an optional closure mechanism 36 are disposed at a top portion 38 of the bag 20, wherein an optional slider 40 is positioned over the closure mechanism 36 and can be moved along a width of the bag 20 to open and close the closure mechanism 36. The optional closure mechanism 36 is preferably in the form of a thermoplastic zipper including first and second closure elements 42a, 42b. The first closure element 42a is disposed adjacent the first bag wall 26 at the top portion 38 of the bag. Similarly, the second closure element 42b is disposed adjacent the second bag wall 28 at the top portion 38 of the bag. The closure mechanism 36 may ...
