A reusable container, made of a thermoplastic material, with at least one filler and drain opening (18) in the top panel (20) and with a circumferential upper and lower stacking ring (12, 16). To permit reuse, direct stackability, good residual drainability as well as good manipulability of the container, this invention provides for the upper stacking ring (12) to have a slightly larger diameter than the lower stacking ring (16) and to feature on the inside of its upper rim a recess matching the diameter of the lower stacking ring (16) and on the outside a vertically protruding circular flange, so that, when stacked one container atop the other, the lower stacking ring of the upper container fits into the recess in the upper stacking ring of the barrel underneath and is snugly centered therein by the vertically protruding circular flange. This allows for the direct, multiple, secure stacking of the containers that are the object of this invention. |
