Abstract
A lid catch on a container driven with superpressure is disclosed. A prestressed spring catch bolt is held in an engaged position due to the pressure exerted on an inner lid of the container which is transmitted by a counterpoise to the bolt. Therefore, releasing of the lid when the container is pressurized is impossible.
