A sealing disc (10) is used for closing orifices of containers (5). It has a film (20) for inductively coupling heat into the sealing disc (10). A sealing layer (25) is provided on that side of the film (20) which is intended to face the interior of the container (5) in order to seal, in sealtight fashion, the sealing disc (10) on the orifice of the container (5). Lines of weakness (26) are provided in the sealing layer (25) so as to form a removal opening (27) once the film (20) has been drawn off. One or more layers (40), which are connected detachably to the film (20), are provided on that side of the film (20) which is remote from the sealing layer (25). The layers (40) detach more easily from the film (20) than the sealing layer (25) and also detach more easily from the orifice of the container (5) than the sealing layer (25). The layers (40) are formed such that said layers tightly close the removal opening (27) once the film (20) has been drawn off and the layers (40) have been placed onto the sealing layer (25) again. |
