ABSTRACT The lid of the invention is suited to be closed by pressure on con- tainers for electric accumulators; without the need for welding or gluing. Said lid (4; 20) presents two perimetric edges (5, 6; 21, 22), each of which goes to contrast against the vertical walls (3, 11; 24) of the container (1; 25) by means of at least a projection (7, 9, 23) for- ming a continuous tightening cord. Moreover, on at least one of the two edges (5, 6; 21, 22) a cog (8,10; 26) is foreseen, said cog being seated in an indentation of the container, thereby preventing it from coming out. The container is of the type obtained with the blow-moulding process and it presents at its upper edge a perimetric indentation (24) or impression (2) with an indentation (11) suited to block at least one cog belonging to one of the two lid edges. The lid has an external edge which does not protrude in relation to the overall surface of the container. By elastically deforming the edges, it is however possible to remove the lid from the container without causing any damage.
