The invention relates to a pressure vessel consisting of a container (1) and a lid (2) for placing thereon, in which case, by twisting them relative to one another, the container (1) and the lid (2) can be detachably locked together by means of peripheral locking segments (3, 4) configured along the lines of a bayonet fastening and a circumferential sealing ring is provided in the region of the edge (5) of the lid (2) and the edge (6) of the container (1) for sealing the interior of the container against a drop in pressure when said container (1) and lid (2) are in the locked position, said pressure vessel including an auxiliary device or aid for the correct positioning of the lid (2) on the container (1) and said positioning aid comprising a downward-projecting positioning element (7) located in the region of the edge (5) of the lid which, when the lid (2) is correctly positioned on top of the container (1), can be inserted into a recess (8) which is open towards the top and is located in the region of the edge (6) of the container (2).
A pressure vessel comprising a container and a lid for placing thereon, in which case, by twisting them relative to one another, the container and lid can be detachably locked together by means of peripheral locking segments configured along the lines of a bayonet catch, and in which case in the region of the edge of the lid and the edge of the container a circumferential sealing ring is provided for sealing the interior of the container in the locked position of container and lid against a fall in pressure, said pressure vessel including an auxiliary device or aid for facilitating the correct positioning of the lid on the container, characterized in that the positioning aid has a downward-projecting positioning element in the region of the edge of the lid which can be inserted, when the lid is in the correct position on said container, into a recess which is open towards the top and is provided in the region of the edge of the container.
