ABSTRACT:
A closure for light gage steel drums made up of an internally threaded closure flange mechanically secured within a suitably formed container wall opening. The flange is formed with a cylindrical neck internally threaded throughout its lower extent and surrounded exteriorly by a polygonally shaped base. A resilient sealing gasket tightly surrounds the flange neck at its juncture with the flange base. A perforated drum stock section is formed to overlie and closely surround the flange neck and base in an improved torque-resisting manner with the upper end of the flange neck beaded outwardly over the surrounding drum stock. The closure is completed with the threaded engagement of a closure plug and application of an overlying tamper-resisting drum seal.
