Stackable plastic barrel with recessed top filling and venting plugs - with gently sloping transition surrounding plug base to barrel top, ensuring complete emptying with small tilt

摘要

Barrel has injection moulded cover (4) welded to blow moulded body and base (2) and integral filling (6) and venting (7) bungs (plugs) which are located in diametrically opposite depressions (8) in the cover (4). To facilitate emptying, the base of the depression (8) for the filling opening (14) is joined to the inside (21) of the stacking surface (16) by gently sloping surfaces (17,18) which surround the depression on each side. USE/ADVANTAGE - For complete emptying of this type of plastic barrel. Compared with existing designs, e.g. DE9001802 UI (SIC), a smaller tilt from the vertical is required in order to completely empty the barrel, so that in daily use this is actually achieved.
