ABSTRACT:
The invention relates to a conical lidded drum made of thermoplastic.
To avoid step-like changes in diameter or hollow borders as a stacking rim on the outer drum body, according to the invention, a second upset surface flange (12) is formed out in the region of the upper third of the drum (34) on the outer wall of the drum body (10). Advantageously, the conical drum wall (14) extends linearly in a straight line from the upper first surface flange (20) down to the vicinity of the drum base (18) over the entire periphery and in drum longitudinal direction. A third upset surface flange may be provided as a bottom rolling ring (38) in the transition region from drum wall to drum base.
