Abstract
An end closure for a packaging container, where the end closure has a central panel and a circumferential rim for being attached to a wall of a packaging container for placing the panel countersunk in the container. A tearing denotation is arranged in the panel and merges into a further tearing denotation extending the whole way around the panel close to the rim. A low ledge is arranged at the side of the panel opposite to the rim for maintaining an easily flexible material covering the underside of the end closure and at least part of the rim outer side thereof at a non-welding distance at both sides of the tearing denotation, i.e. at such a distance that the temperature and pressure is insufficient for heat sealing or welding of thermoplastics material on the flexible material and/or the panel.
