Abstract

A pressure vessel includes a pot-like receptacle and a lid for placing thereon, the two being detachably locked together and including a circumferential sealing ring made of elastically yielding material which is located in the region of a circular edge of the lid and a circular edge of the pot for the purpose of sealing the interior against a drop in pressure. Sealing lips of the sealing ring come into close contact with the edge of the lid and the edge of the receptacle, in which case, for producing an automatic pressure-control mechanism, the sealing ring is formed over at least one portion of its circumference in such a way that it is deformed, under a pressure inside the vessel which exceeds a given value (response pressure), so as to form a venting gap between the receptacle and the lid.
