ABSTRACT:
A child resistant closure having a visible external locking tab which cooperates with a locking stop on a container. A threaded inner cap remains sealed while the child resistant locking tab is locked from the position of locking to a tightened position. An outer cap is rotated to engage cooperating drive means for closing or opening the closure. When the closure is reapplied, the user is assured that it is sealed when he observes that the child resistant tab is engaged.
