ABSTRACT:
A blow molded synthetic thermoplastic barrel one end wall of which has an eccentric opening surrounded be a ring-shaped mouth which, in turn, is surrounded by an arcuate groove having two open ends. The opening can be closed by a cover whose outer side is then flush with the outer surface of the major portion of the one end wall. Such outer surface is surrounded by a bead which can surround the other end wall of a second container when the two containers are stacked end-to-end. For the stacking of several containers side-by-side, the circumferential wall of the barrel has two longitudinally extending flats located diametrically opposite each other. The circular end portions of the flats extend into the domed end portions of the circumferential wall and close to the respective end walls.
