摘要

Quick acting closure comprises segments with protrusions interacting with peripheral grooves of a flange (8) on the outer periphery of the lid (4). Each segment is fixed to the periphery with a guide with a slit and a peripheral annular chamber impinged by a pressure medium is assigned to a seal (9). Preferred Features: The seal is impinged by compressed air and seals the lid. The compressed air is guided from a compressed air network via a connection (11) into the annular chamber of the flange.
