ABSTRACT:
A metered dosage unidirectional tracked pump dispenser of the present invention comprises a liquid pump which includes a pump handle and nozzle, and a circular housing containing a reciprocal pump mechanism which is connected to the nozzle. A circular sleeve, which may be a container neck, the housing, a pump handle wall or a separate component, is included and has either at least one guide protrusion, or has at least one track located on the said sleeve, the track being adapted to receive the guide protrusion. The track has a virtual continuous loop for control of pump cycles. There are also at least two vertical paths parallel to and separate from each other. One of the vertical paths has upward flowing ratchets which permit movement of a guide protrusion upwardly and prohibit downward movement. The other of the vertical paths has downward flow ratchets which permit movement of a guide protrusion downwardly and prohibit upward movement of the guide protrusion.
