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 at least one finger spring member being inwardly directed and contacting the inclined surface of the inner closure member, thereby biasing the outer closure member into an operationally disengaged position. The finger spring member T-shaped in cross-section.
