Abstract
A cover which is to be sealed tightly to the corresponding plastic container of a battery cell by means of radiant heating is provided with a series of molded knobs along the lower side of its edge, which knobs serve as spacers between the cover and the edge of the container during the heat-up phase so that the surfaces to be bonded are exposed to the radiant heat without obstruction. The softened knobs are plasticized and bonded when the container and the cover are subsequently pressed together.
