PCT No. PCT/EP94/00777 Sec. 371 Date Sep. 8, 1995 Sec. 102(e) Date Sep. 8, 1995 PCT Filed Mar. 14, 1994 PCT Pub. No. WO94/21524 PCT Pub. Date Sep. 29, 1994A sealing cover for an opening of a container has a first foil that seals the opening of the container. A metallic foil, especially aluminum foil, is also provided for inductive sealing of the first foil at the lip of the opening, along with a removable sealing lid that is releasably screwed onto the container. A releasable adhesive control layer positioned between the first foil and the metallic foil, enables the metallic foil to be detached from the first foil after the sealing lid has been removed. An elastic layer is provided between the sealing lid and the metallic foil. Between the metallic foil and the elastic layer is a separation layer, which becomes liquid at induction temperatures, and a suction layer. During the induction process, the latter absorbs the liquified substance of the separation layer. The adhesive control layer does not have such an adjoining suction layer.
