Abstract: A drainable ostomy or similar pouch (22) is provided with a closing means (10) which in principle is a clip of known type encapsulated between two layers of plastic sheet material, preferably of the same kind as that constituting the pouch walls (24,26) which are joined together by a seam 28. At least one of the layers of plastic sheet material encapsulating the clip is integral with a pouch wall. If only one of the layers of sheet material encapsulating the clip is integral with the pouch wall, a discharge opening (34) of the pouch is situated at the very bottom of the pouch, between its walls. If both of the layers of sheet material is integral with the pouch walls, the discharge opening (34) is a slit adjacent a hot-melt seam serving to join the layers encapsulating the clip, between that seam and the remainder of the pouch wall in question.

Abstract: A disposable closure for an artificial or an incontinent natural intestinal opening has a porous, elastic, air-filled body which in a state not influenced by external compressive forces is a substantially cylindrical, conical or bell-shaped structure having a cross-sectional area, measured halfway between its ends, of at least the double of the cross-sectional area of the intestinal duct for which it is intended. When supplied by the manufacturer, this elastic body is compressed to a substantially cylindrical shape having a cross-sectional area as or slightly below that of the intestinal duct in question. The elastic body is maintained in that compressed state by a moisture- and/or heat sensitive material, the shape-maintaining effect of which is rapidly eliminated upon contact with the moisture content of the intestine and/or the heat of the human body. The elastic body may for instance be made of a foam plastic and the shape-maintaining material may for instance be a cover of polyvinyl alcohol.
