Lid-type closure, in particular that for pressure vessels

摘要

The cover device (100) for especially a pressure vessel has a lever element (110) which engages in a recess (46) in the cover (10). The recess has a contour which after a vertical rotation of the lever on a rotational axis (32) vertical to the cover corresponds in at least one position with a contour of lever stop (16), and the container mouth is opened and closed by the cover only in this position. The dome (24) of the container has a dome flange (26) which by a seal (28) between a cover sealing face (30) and the dome flange is sealed via the lever element transmitting forces in the direction of the dome flange.
