A reusable container, made of a thermoplastic material, with at least one filler and drain opening (,) in the top panel (,) and with a circumferential upper and lower stacking ring (,). To permit reuse, direct stackability, good residual drainability as well as good manipulability of the container, this invention provides for the upper stacking ring (,) to have a slightly larger diameter than the lower stacking ring (,) and to feature on the inside of its upper rim a recess matching the diameter of the lower stacking ring (,) 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.

Stackable re-useable container

Stackable re-usable container

A container has a neck formed with projections and a closure assembly for attachment to the neck and movable between a fully released position and a fully closed position. The closure assembly includes a screw cap and an index ring which serves as tamper-evident safety mechanism and is connected to the screw cap via several thin bridge portions forming predetermined breaking points and torn off when the screw cap is released from its fully closed position for the first time for the first time. The neck and the index ring are formed with mutually engaging locking elements (ratchets 36, flexible tongues 34) which are so moved that a tightening of the screw cap from the fully released position into an intermediate position results in at least two of the first locking members of the index ring to engage with the second locking members such that a spontaneous unscrewing and release of the screw cap is prevented while still allowing unscrewing of the screw cap by overcoming a certain retention force applied by the first locking members.
