Abstract
A receptacle for particulate matter to be supplied to a reproduction apparatus. The receptacle includes a container, adapted to store particulate matter, has an opening defined therein. A flange is located about the defined opening so as to facilitate placement and removal of the receptacle with the reproduction apparatus. A breathable seal member is provided having a body portion and a readily accessible end portion. The body portion is bonded to the flange for covering the defined opening. The bond is particularly formed in a pattern of repeating minimum and maximum distances from the defined opening to reduce the forces required to break the bond and remove the breathable seal from the flange.
