Abstract
A child-resistant closure assembly is disclosed which includes inner and outer cap members in a nested configuration. Leaf spring and ratchet elements are respectively provided on the cap members whereby torque can normally be transmitted from the outer cap member to the inner cap member only in the closure tightening direction. For transmission of torque in the closure removal direction, drive lugs on the inner cap member are engageable in non-concentric apertures formed in the panel of the outer cap member. The drive lugs and apertures are normally maintained axially out of engagement by the leaf springs formed on one of the cap members. When the leaf springs and ratchet elements are transmitting closure tightening torque, the non-concentric apertures are angularly displaced relative to the drive lugs. The apertures may be visually aligned with the driving lugs by reverse rotation of the outer cap and then the outer cap is axially shifted to engage the driving lugs in the apertures for removal of the closure assembly.
