Abstract
Abstract There is provided a plural part receptacle assemblage for the storage and handling of bulk quantities of material which assemblage includes a tight-head plastic drum molded as a single article to which is concentrically attached, subsequent to the formation of the drum, handling means so arranged and constructed as to be grippable about substantially the full 360° circumference of the drum with steel drum chime-handling devices for transportation of the assemblage and the bulk quantities of material stored in the drum; preferably the drum or handling means, or both, include means for preventing liquid accumulation between the handling means and drum.

Total Claims: 14
Claim 1
Independent Claim
243 words
A plastic drum assembly for the storage, handling and shipment of materials, said assembly comprising, in combination, a single piece molded plastic drum having a top end panel, a bottom end panel and a circumferential sidewall merging with said top and said bottom end panels, said top end panel defining an opening, said circumferential sidewall including a circumferential indentation adjacent said top end panel, and a circumferentially disposed collar member assembled to said drum, said collar member comprising a generally circumferentially disposed collar sidewall; said collar being at no point higher than said top end panel and terminating at its highest portion in a bead-like portion which merges with said collar sidewall at the top thereof and projects radially outwardly from said sidewall of said collar, and which is spaced apart from, and does at no point in its circumference touch, said drum and is thus adapted for gripping about substantially the full 360° of the collar circumference, by the opposed jaws of a steel drum chime-handling device having two opposed movable jaws to holdingly grip the collar with one jaw engaging the inside surface wall of the bead and the other jaw engaging the outer underside surface of the bead; and a radially inwardly disposed circumferential projection near its lower edge, said circumferential projection and said circumferential indentation being inter-engaged to retain said collar on said plastic drum while the drum is manipulated by such handling device which holdingly grips said collar.
