Abstract
A child resistant closure which can be readily opened by an adult comprising an outer closure member having a base wall, a peripheral skirt and a bead on the outer closure member for retaining an inner closure member for limited axially outward movement relative to the outer closure member. A push tab is hinged to the base wall of the outer closure member and projects through an opening in the base wall of the outer closure member. The push tab can be depressed into a plurality of spaces provided between circumferentially spaced ramp-type projections or castellations on the inner closure member. One of the castellations is provided with a stop surface such that when the push tab is depressed in that location, as indicated by indicia on the outer closure member and inner closure member, the closure can be unthreaded from a container to remove the closure. Further, the outer closure member can also be removed by axial movement of the outer closure member relative to the inner closure member to engage ribs and additional projections on the respective outer closure member and inner closure member so that the closure can be rotated to unthread it from a container.
