Abstract (en)
[origin: EP0967160A1] The membrane (11) has an inner and an outer film (15,16), and a connection layer (17) with a seal seam zone (13). The seal seam zone contains an intermediate space (21) without connection layer, and outer and inner films having an opening (20,19) within a space containing a material (18), which softens when heated. The openings of outer and inner films are connected for a fluid flow (23). When the membrane is subjected to heat, the openings in the films are sealed due to softening of the material. The cover is for bottles, jars, goblets, bowls, of plastic, ceramics, glass, metal, and for bags.
