ABSTRACT:
A child resistant finger pump dispenser having a vertically oriented body member or tank. The tank has a piston therein with an attached hollow outlet stem extending out of its upper end. An actuator button is attached to the upper end of the stem and has a laterally directed spray nozzle extending from the side of the skirt portion of the actuator. A housing has an upper portion that partially surrounds the actuator button and a lower portion that supports the tank and includes a depending skirt having a multiplicity of short threads with projections adjacent their ends on the inner wall of the downwardly depending skirt. The container neck is provided on its outside surface with a multiplicity of interrupted threads, some having recessed portions on their underside adjacent their terminal ends to receive the projections on the threads on the closure member skirt portion. The upper portion of the housing has opposed flat portions on its inner sidewall which cooperates with opposed flat surfaces on the actuator to prevent rotation of the spray nozzle. The short threads on the lower skirt portion are so positioned that when the housing is attached to an oval or non-cylindrical container having the interrupted threads with the projections on their ends that the short threads of the closure will engage the undercuts on the long threads of the container so that the spray nozzle of the pump is parallel to the major transverse axis of the container to provide fixed orientation of the pump with respect to the container.
