The vessel for a chemical current source is constructed integrally from plastic, with identical opposite walls, has the shape of a box with sides that are not equal and rounded ribs (5, 6, 7, 8, 9) and is provided on its upper wall with cast-on projections (14) for the terminal leads and with a connecting piece (15). The vertical ribs (5) project out of the side walls (1, 2) and the horizontal ribs (6), which are arranged parallel to the vessel length, project out of the base wall (3). All the ribs (5, 6) have hollow-conical transitions (10, 11) to the walls (1, 2, 3), with radii (R1, R2) which are at least equal to the maximum distance (L1, L2) between the surface of the rib (5, 6) and the wall (1, 2, 3). The ratio of the maximum distance (L1, L2) between the surface of the rib (5, 6) and the wall (1, 2, 3) to the width (a) of the ribs (5, 6) is approximately 0.05 to 0.3. The vessel has at least two additional reinforcing ribs (12, 13) which are arranged parallel to the width of the vessel. The ratio of the height (h1, h2) of the reinforcing rib (12, 13) to its width (a) is at least 1, one reinforcing rib (12) being arranged on the base wall (3) and the other (13) on the upper wall (4), and running through the cast-on projections (1, 4) for the terminal leads. The invention can be used particularly advantageously for alkaline accumulators. <IMAGE> |
