| 摘要 |
The invention relates to a pressure vessel comprising a pot-like receptacle (1) and a lid (2) for placing thereon, the two being detachably locked together preferably by means of peripheral locking segments of a bayonet catch, and including a circumferential sealing ring made of elastically yielding material, wherein in the circumferential portion (L) of the sealing ring where at least the sealing lip associated with the edge (6) of the vessel with its continuous circumferential sealing surface (11) is reduced or tapered, said sealing ring is provided with at least one pressure-release pocket (12) opening towards the interior (8) of the vessel, so that - in use - when the predetermined response pressure is exceeded, the sealing lip resting tightly against the edge (6) of the vessel is displaced radially outwards and downwards into an intermediate space (13) between the edge of the lid and the edge (6) of the vessel. |
