ABSTRACT:
A closure and container in which the closure has an axial flange which cooperates with the container to lock the closure in closed position, the closure also having an annular recess accommodating a resilient seal for sealing against the container rim. The seal projects from the recess before assembly of closure to container. During assembly, the container compresses the seal into the recess until in the fully closed position, the container engages a seating surface upon the closure, at which point the seal is only partially compressed.
