Patent ID: 7870967

Claim:
A vial comprising a container including a receptacle formed to include an interior region and a mouth opening into the interior region, an inner retention lug coupled to the receptacle and located inside the interior region, and an outer retention lug coupled to the receptacle and located outside the interior region, and a child-resistant closure including a cap configured to be mounted on the receptacle in a closed position to close the mouth and separated from the receptacle to open the mouth and a lift-tab coupled to the cap, the child-resistant closure further including an inner cap-retention latch mated to the inner retention lug upon movement of the cap to the closed position to resist separation of the cap from the receptacle, an outer cap-retention latch mated to the outer retention lug upon movement of the cap to the closed position also to resist separation of the cap from the receptacle, and first-stage cap-release means for disengaging the inner cap-retention latch from the inner retention lug during a first stage of cap removal to allow the cap to be decoupled from the receptacle upon upward movement of the lift-tab relative to the receptacle to disengage the outer cap-retention latch from the outer retention lug during a subsequent second stage of cap removal to release the cap so that the cap can be moved relative to the receptacle to assume the opened position separated from the receptacle.
