ABSTRACT:
An ostomy pouch (10) includes a front wall (12) provided with a comfort layer (16) and a vent (22). An apertured cover layer (24) is secured to the front wall (12) through the comfort layer (16) to define a chamber for a filter element (28) and to provide a smooth surface to which can be applied an adhesive sticker. The cover layer (24) includes a plurality of apertures (30), and the flow rate through the vent can be controlled by positioning the sticker to selectively block one or more of the apertures (30). An adhesive wafer (40) includes both circular and non-circular (race-track) cut-out guidelines for enabling the aperture to be cut to any desired shape and size. The wafer (40) is secured to the pouch along a weld line having a shape corresponding to a combined circular and race-track silhouette.
