A plastic accumulator cover (1), which can be plugged into cell vessels, has a moulded terminal duct (4) in the openings (3) for the cell terminals, and, along its outer edge, has a moulded ring seal (6), both mouldings consisting of a material (synthetic rubber), which has soft-elastic properties in comparison with the cover material (PP). From the formed-on sealing lips (5, 7, 9), the separate sealing lip (9) produces a tub effect on the ring seal, by pressing the cover into the cell vessel, as a result of which the overflowing electrolyte is retained so that no leakage flows occur. <IMAGE> |
