ABSTRACT:
The inventive container seal comprises a cover (4) and a rim ring (3) die cast as a unit. In said unit the cover (4) and the rim ring (3) are mutually connected by a radial ring rib (10), said ring rib forming an area of fracture, which is ruptured when the cover is pressed down into the rim ring. At the same time or later the rim ring (3) can be pressed into the mouth (2) of a container. The rim ring (3) is reinforcing the container wall so that an outer stiffening bead is superfluous.
