A cap for a hermetically sealed container includes an interior spike and a unitary security ring which is severed from the cap when an attempt is made to remove the cap from the container. The cap is rotatable in one direction to pierce through and puncture the neck of the container and allow access to the container contents. The security ring is severed from the cap when an attempt is made either to remove the cap from the container or to pierce the neck of the container with the interior spike.
