Abstract: A drainable ostomy pouch is disclosed having generally parallel sidewalls of flexible sheet material joined along their edges to define a chamber therebetween and having a downwardly extending neck portion terminating in a discharge opening for draining the contents from the chamber. The neck portion of the pouch has first and second transversely extending curved spring members associated therewith and is closed by folding the neck portion upwardly. The first curved spring member is located nearer the discharge opening than the second curved spring member and each of the curved spring members is curved smoothly and outwardly relative to the neck portion. The curved spring members are located relative to one another so the first curved spring member nearer the discharge opening nests with the second curved spring member when the neck portion has been folded upwardly and can be secured using a two-part fastening system during use of the drainable ostomy pouch.
