Abstract:
A dispensing closure is molded as a base having an end wall with a dispensing orifice and a lid having a fixed section and a moveable section joined by an integral hinge. The fixed section of the lid is mounted on the base by a socket and plug connection in which the socket includes a central prong and the plug has a central recess. The socket and plug are sized for an interference fit, but with chamfered edges providing a lead in. In addition, the recess in the plug is tapered at a greater angle than the prong in the socket, so that as the plug engages the socket and the prong enters the recess in the plug, the plug is wedged outward into tight engagement with the socket. Extensions or wings on the moveable section of the lid created by offset of the integral hinge have inwardly projecting knobs which cooperate with outwardly projecting ribs on the raised member on the bare end wall in which the socket is formed.
