Abstract: In a spigoted barrel of a synthetic resin, welded together from two or more parts, with a sidewall section, a head section, and a lid section, exhibiting bungholes (e.g. 9) hidden in depressions, a barrier (13) is integrally molded to the inner surface (12) of each depression (e.g. 11) of the lid section (4), this barrier extending in an arcuate shape from the sidewall section (14) around the respective bunghole (9) and constituting a collecting pan for a residual content (16) of the barrel. Thereby, upon tilting of the barrel, complete emptying becomes possible. The barrier (13) is lower in the zone around the bunghole (9) than in the regions toward the sidewall section (14) so that the barrier (13) does not form a hindrance during cleaning of the barrel.

Abstract: A drum apparatus includes an injection-molded or extruded rim member formed into a ring shape and permanently attached to a blow-molded thermoplastic drum body around the top portion of the drum adjacent to the sidewall section of the drum body. The rim member includes an inwardly, radially projecting annular protuberance which is juxtaposed adjacent an annular groove in the drum just below the top of the drum. The rim member is attached to the drum while the rim member is at an elevated temperature by positioning the rim around the drum. As the temperature of the rim member decreases, the diameter of the rim member decreases causing the annular protuberance to seat into the drum's annular groove. The rim member also has a grasping beak which provides an outwardly extending support lip, a top edge providing a stacking ridge which is positioned vertically over the sidewall of the drum, and an annular seizing surface facing radially inwardly. A short chain hoist groove is formed in the bottom of the drum.
