ABSTRACT:
A child resistant closure having an inner cap and an outer cap. The inner cap is normally biased into engagement with the outer cap for screwing the closure onto the container but the outer cap and inner cap become disengaged when the outer cap is turned in a direction to remove the closure from the container resulting in the outer cap being freely rotatable on the inner cap. Cooperating rigid fingers and teeth are provided on the inner and outer caps which become engaged when the outer cap is pushed downwardly to interconnect the inner and outer caps so that the closure can be removed from the container.
