The cell-container, obtained by blow-forming, thus having a minor thickness, presents at the upper-rim a conformation in two steps (1) permitting the mating of the cell-lid to the cell-container remaining within unified overall-dimensions, as the welding-bead between the cell-lid and the cell-container forms itself on the inside instead of on the outside of the same. Furthermore, it becomes possible to increase the welding-surface according to one\s need if the cell-container is cut in correspondence with the flat-part of the step. The cell-container presents, furthermore, horizontal-recessings at various levels permitting the modular-cutting of the product according to unified measures. The cell-lid\s form is concave towards the exterior in order to follow the dilatations of the poles during the service-life of the battery. The cell-lid is also furnished with a molded ring, which has a circular profile around the electrolyte\s inlet thus avoiding the application of a gasket onto the top-cover.

Cell-lid for the electric-accumulators molded in polypropylene-copolymer, characterized in that it has a concave surface turned towards the outside of the cell-container and a profile of the section of the cell-lid which extends downwardly from the rim to a central area where said profile is connected with bushes of accumulator\s poles and with a central-inlet of the electrolyte-solution in order to enable the poles, rigidly welded to the bushes incorporated in the cell-lid in the molding-process, to elongate during the service-life of the accumulator itself, as said cell-lid can, without any deformation-damage, follow such elongations while being hermetically hot-sealed to the cell-container.
