Abstract
Abstract An annular mounting member is bonded to the pouch wall to define a vent opening. The mounting member is made of material which is compatable with the pouch film and has a smooth exterior surface adapted to facilitate removable mounting of an adhesive coated element in alignment with the opening. The element may be a deodorizing filter assembly including a filter disk surrounded by an annular border member coated with pressure sensitive adhesive or a gas impermeable cover member designed to close the vent.
