<p>A closure lid (12) for a connecting element (11) of a computer container (10), comprising an inner part (22) which is maintained on an outer part (21) of said lid and which is provided with an annular groove(26) on the outer periphery thereof (26), said groove being defined by an annular web (28) on the outer side of the lid and having a sealing ring (27) inserted therein. In order to provide a closure lid (12) which is embodied in such a way that it is possible to prevent the sealing ring (21) from being raised radially from the base of the groove as a result of existing pressure and therefore to relieve the pressure inside the container before the open position of the closure container (12) is reached, the annular web (28) disposed on the outer side of the lid is provided with an uneven bearing surface (32) for the sealing ring (27).</p> |
