Abstract
A snap closure with original seal safety is particularly suited for bottles with bulging rim areas on the bottle neck. The original safety sealing takes place by means of a release element, which comprises a pressing element which is bounded on both sides by weak points. The release element forms a portion of the circumferential wall. In order that the release element not be torn further than desired, the weak points proceeding in the axial direction of the closure reach only into the area of an annular bulge positioned on the internal surface of the circumferential wall. The release element itself, which has at least one corrugation, is connected with the circumferential wall by means of a film hinge, and can pivot by 90 degrees upon destruction of the weak points.
