ABSTRACT:
A child resistant dispensing closure comprising a first part having a base wall and a peripheral skirt adapted to be threaded onto a container. The peripheral skirt includes interengaging portions that engage portions of the container to prevent removal from the container. The closure also includes a second part or lid connected to the first part by an integral hinge and having a base wall, peripheral skirt and a closing portion adapted to extend into a nozzle on the base wall of the first part when the second part is moved into overlying relationship to the first part. Snap lugs on the second part engage bead segments on the firt part to hold the second part in closed position. The diameter of the skirt of the first part includes a radial flange that extends circumferentially about most of the periphery of the skirt. The flange is connected integrally to an outer radially deflectable wall panel. The skirt of the second part is smaller than the diameter of the flange so that the flange projects radially beyond the lid skirt and the lid skirt cannot be raised readily. A shoulder projects axially from the flange to center the lid and support the skirt against radial deflection. By pressing the deflectable wall panel radially inwardly the panel engages an axial rib on the skirt of the lid camming the skirt of the lid upwardly and exposing it so that it may be opened.
