ABSTRACT:
A one-piece blow-molded closed plastic drum having an integrally-formed compression-molded handling ring and method of molding same is provided. The drum has structural strength and stability to resist breakage of the drum upon impact due to tipping or dropping of the drum. The drum includes a generally cylindrical body portion and a head portion integrally-molded with an upper end of the body portion including a transition area around and between the upper end of the body portion and a top of the drum in the head portion. The transition area has an outside curved surface of a predetermined radius so that an outside surface of the body portion is positioned in a tangential plane in close proximity to a tangential plane along the outer circumferential surface of the handling ring and/or an inside curved surface with at least one radius, preferably a double ogee with three predetermined radii, so that no acute angles are formed between inside surfaces at the transition area.
