Patent

CA 2075283

A closure ring (11) for use with an open head drum (11) utilizes a reduced diameter portion (26) proximal each end thereof to increase the force required to draw the end of the ring together about the drum head and an associated lid (16) and gasket (13), thereby increasing the compressive force applied to the gasket (13) in the reduced diameter region resulting in greater sealing ef- fect at the junction of the ring ends (18, 19).
