Abstract
An industrial sized drum that may be blow-molded of polyethylene is constructed with integrally formed rolling hoops, a domed top having an interrupted chime of generally arcuate cross-section undercut on its interior side, necks extending upward from a pair of diametrically opposed bungholes, symmetrically disposed dimples in the drum top adjacent these necks to maintain ovalization. The necks are formed to facilitate crimp-type securement of closures by crimp-type techniques. The drum bottom is formed with a chime and a sump pad aligned with one of the bungholes.
