Zusammenfassung:	The lid over the container opening (11) comprises a cover foil (14) and a sealing film (16) joined over its surface to the foil. The foil has an opening line (17) in the opening area (11) and is closed here by the film (16) so that the film tears open along the line (17) under a pre-set applied force. The opening line (17) is made up of eight slots (17) in the foil (14) which demarcate circular sectors joined permanently to the container rim (20), the slits passing right through the foil thickness. In a variant, the opening line forms a shear-off area between container wall and foil (14) edge, the foil in turn connected to the container (10) through the continuous sealing film. When the lid forms the cap of a pressurised container, e.g. fire extinguisher, the foil designed as a cup moulding is bonded at its non-slit wall to the film edge.
