The invention relates to a cap-like closure system for containers, in the form of crown caps, which have a plurality of jag- or tooth-like shape ends. Said crown caps are composed at least partially of a metal and/or aluminum-containing material (main body) and can comprise an inner coating composed of one or more layers (rubber, plastic) for improving the sealing between the container opening and the underside of the crown cap. The crown cap is shaped in such a way that the shape ends have the fundamentally known corrugated or jagged radial contour after the intended deformation which closes the opening of the container, such that one or more cavities are formed between the outer container surface close to the opening and the shape ends. A deformable sealing material is provided in the region of the shape ends. The sealing material closes the cavities at least in the periphery of the end pointing toward the container bottom. The sealing material is a ring- or hoop-like element, which is separate from the crown cap and is attached in the corresponding opening region of the container separately from, i.e., independently of, the main body of the crown cap. However, said element then interacts with the crown cap (main body) in such a way that, when the shape ends of the crown cap are deformed for the final container closure, said form ends press or sink into the sealing material at least in some sections. |
