Open-head drum
A drum with a fully removable lid, closed by a ring and clamp.
Also called a full removable head. The whole top comes off, so the drum can be filled with pastes, solids, powders or parts, cleaned out, and lined easily. The seal depends on the gasket and the closing ring rather than a threaded plug.
