Abstract
A child resistant closure for use on a container that include an inner closure member having a threaded portion and an outer closure member coupled to the inner closure member for axial translation there between. A series of engagement features extend between the inner and outer closure to permit selective engagement of the outer closure to the inner closure to effect removal of the child resistant closure. The outer closure includes a diaphragm member disposed along the distal end surface of the outer closure. The diaphragm member is inwardly directed and contacts the inner closure member thereby biasing the outer closure member into an operationally disengaged position.
