ABSTRACT:
A cap threadedly receivable on a severable cover of a hermetically sealed container is provided. The cap has a reduced surface area for engaging an annular bearing surface of the container. Screwing the cap further down onto the container transmits oppositely directed forces to the container body and to the container cover, thereby severing the cover from the body.
