Abstract (en)

[origin: EP1078863A1] The membrane (5) has a closure cover (7) and a retainer flange (10) joined to the cover via a connector wall (8) to form a pot-shaped arrangement. At least one slot opening (16) in the cover is intermittently filled in along its length. Preferably three slots, all filled in intermittently, extend outwards in a radial direction from the middle of the cover to form a star-shaped pattern. A bridging section of cover material is left behind to fill in part of the slot and divide it into two sections which have different lengths.
