ABSTRACT:
A special lock-unlock device for use with sealable, releasable and resealable containers such as paint cans which allows for opening and closing without use of impact forces. This is accomplished by a dual acting cam lug which operates with an associated cam surface adjoining the container cover to cause exertion of pressure to open and unseal the container when the bail is pivoted in one direction and conversely, to close and seal the container when the bail is pivoted in an opposite direction.
