First Claim
Patent Images
1. An ostomy pouch, comprising:
- a proximal and a distal side wall of flexible sheet material joined together along their peripheral edges to define a cavity therebetween, the side walls also being joined in at least one location inwardly of the peripheral edges to thereby limit the separation of the proximal and distal side walls, the side walls including a laterally outwardly expandable fold formed by at least a portion of at least one of the side walls.

Abstract
An ostomy pouch is disclosed which comprises a proximal and a distal side wall of flexible sheet material joined together along their peripheral edges to define a cavity therebetween. The side walls are also joined in at least one location inwardly of the peripheral edges to limit the separation of the proximal and distal side walls. With this construction, the side walls also include a laterally outwardly expandable fold which is formed by at least a portion of at least one of the side walls.

11. An ostomy pouch, comprising:
a pair of side walls of flexible sheet material joined together by welding along their peripheral edges to define a cavity therebetween, the side walls also being joined in at least one location inwardly of the peripheral edges to limit the separation of the side walls as the cavity fills with human stomal discharge, the pouch including at least a pair of opposite sides each including a laterally outwardly expandable fold formed by at least a portion of at least one of the side walls, the folds expanding laterally outwardly as the cavity fills with human stomal discharge to accommodate an increasing volume. - View Dependent Claims (12, 13, 14, 15, 16)

17. An ostomy pouch, comprising:
a pair of side walls of flexible sheet material joined together by welding along their peripheral edges to define a cavity therebetween, the side walls being joined by welding in a plurality of spots inwardly of the peripheral edges to limit separation of the side walls as the cavity fills with human stomal discharge, the pouch including a pair of opposite sides each including a laterally outwardly expandable fold formed by at least a portion of at least one of the side walls, the folds expanding laterally outwardly as the cavity fills with human stomal discharge to accommodate an increasing volume, whereby the increasing volume of human stomal discharge is accommodated while at the same time maintaining a limit on separation of the side walls during use of the pouch. - View Dependent Claims (18, 19, 20)
