ABSTRACT:
This invention relates to two-piece child resistant closures which utilize a ratchet feature to screw on the closure and, more specifically, to a two-piece child resistant closure wherein a particular ratchet configuration and placement of the elements thereof provides negligible reverse torque during undepressed counter-clockwise rotation of the outer closure member. Negligible reverse torque is defined as the torque caused by frictional contact of the outer and inner cap members when the undepressed closure is turned in the removal direction is insufficient to cause the undesired or accidental removal of the closure from the container.
