Abstract
Crown caps comprising jag-like or tooth-like shaped ends, wherein one or a plurality of cavities is formed between an outer container surface and the shaped ends, and wherein in the region of the shaped ends a deformable sealing material is provided which closes the cavities at least to the extent of the edge of the crown cap that points to the base of the container, with the sealing material forming a ring-like or hoop-like element separate from the crown cap and which interacts with the crown cap in such a way that when the shaped ends are deformed for the container closure they press or sink into the sealing material.
