Abstract
An ostomy pouch ( ) includes a front wall ( ) provided with a comfort layer ( ) and a vent ( ). An apertured cover layer ( ) is secured to the front wall ( ) through the comfort layer ( ) to define a chamber for a filter element ( ) and to provide a smooth surface to which can be applied an adhesive sticker. The cover layer ( ) includes a plurality of apertures ( ), and the flow rate through the vent can be controlled by positioning the sticker to selectively block one or more of the apertures ( ). An adhesive wafer ( ) 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 ( ) is secured to the pouch along a weld line having a shape corresponding to a combined circular and race-track silhouette.
