ABSTRACT:
Bunghole-equipped barrel of a synthetic resin with a blow-molded sidewall with a bottom, and with a lid made of a plastic injection-molded component with integrally molded-on bungholes. The lid (4) has a central, trough-like indentation (9) which in a substantially upended position (1') of the barrel (1), forms a shallow drainage dome (10) sloping downward toward the bunghole orifices (7, 8). The lid (4) has an outer ring (12) having an L-profile serving as a supporting ring, carrying ring, and roller chime, projecting past the bungholes (5, 6) in a direction parallel to the longitudinal axis (11--11) of the barrel. Ridges (15, 16) extend from the lid (4) at a spacing around the bungholes (5, 6) and have the same height (17) as the outer ring (12) for protecting the bungholes (5, 6) and for supporting a stacked barrel.
