Abstract:
1. A sealing disk for placement in a screw cap, for closing an orifice of a container and having respective opening and closed positions relative to the container, said sealing disk comprising: a heat induction layer comprised of one of a metal foil and a metal film for the inductive coupling of heat into the sealing disk, a sealing layer that is attached on the side of the heat induction layer that faces the interior of the container in order to tightly seal the sealing disk on the orifice of the container, said sealing layer having weakness lines in the sealing layer for forming a removal opening in the sealing layer after pulling off the heat induction layer, at least a support layer connected detachably to the heat induction layer on the side of the heat induction layer facing away from the sealing layer, said support layer, during opening of the sealing disk, detaching more easily from the heat induction layer than the sealing layer detaches from the heat induction layer, said support layer, during opening of the sealing disk, detaching more easily from the heat induction layer than the sealing layer detaches from the orifice of the container, and said support layer, in the closed position of the sealing disk being formed so as to tightly close the removal opening wherein the support layer is threaded onto the container by means of respective screw threads associated with the support layer and the container, after the heat induction layer has been pulled off and the support layer is again placed on the sealing layer.
