Abstract
A child resistant closure cap is detachably fastened over a peripheral flange associated with a container. The cap has a peripheral bottom flange upon which is located a plurality of fulcrum members which rest upon the top edge of the container flange. Located beneath a selected number of fulcrum members is a projecting undercut, which undercut as positioned underlies the container flange. One of the undercuts is not associated with a fulcrum member and above this undercut, a force is applied by a user to cause the cap to pivot about the fulcrums releasing the same from the container.
