ABSTRACT:
A barrel for initial use as a bunghole barrel having a bunghole lid with a filling and emptying bunghole, as well as an aerating and venting bunghole, a lid flange and barrel border. The lid flange and the barrel border have a spacing when the lid is closed, and are welded together by a continuous sealing web 20 coaxial to the barrel axis. The bunghole barrel may be reconditioned for further use by removing the sealing web and retrofitted as a wide mouth barrel having a lid with clamping-ring closure, or a removable bunghole lid, or as a bunghole barrel having a bunghole lid welded onto the barrel body by a sealing web.
