Closure for cylinder jacket-shaped sealing surfaces, in particular for bottles and glasses, and as connection elements for hoses and pipes

摘要

The object of the invention is to provide a sealing closure for a cylinder jacket-shaped container opening. Both the openings of narrow neck and wide neck containers, in particular of glass, should be closable. Likewise, to be provided with the invention connections of hoses and pipes and related fittings. Furthermore, the requirements of a simple and quick, tool-free handling and a high reliability and safety, especially with repeated use, are fulfilled. The invention is a plug closure with gripping edge (5) for sealing to the inside of a cylinder jacket-shaped sealing surface ( 2) of a container. In a resiliently formed closure portion (1) of the plug closure, a cavity (8) is formed, between the cavity (8) and the environment, a valve (9) is arranged and the cavity (8) via the valve (9) with a pressurized gas fillable. In one variant, the lid bottom of a screw cap closure for sealing to the inside of a cylinder jacket-shaped sealing surface of a container on the inside in the cylinder jacket-shaped sealing surface of the container (2) is retracted and in one of the inner wall of the container mouth (2) opposite cylindrical annular edge portion (13) is a Sealing rubber (14) arranged and the sealing rubber (14) is thus positioned between the peripheral edge portion (13) and the inner wall of the container mouth (2), wherein the sealing rubber (14) is formed as a hollow profile or with a conical profile.
