ABSTRACT:
A pump actuating system is associated with a container having a pump for dispensing the container contents. The system includes a housing mounted on the neck of the container and at the same time the housing serves to couple the pump with the outlet end of the container. The pump is of the reciprocal type having a reciprocating plunger which also serves to direct the container contents away from the pump. A conduit couples with the pump outlet and serves to direct the pumped container contents either coaxially with or transversely of the axis of the neck of the container in accordance with the selected dispensing pattern. An actuator is mounted by the housing and is coupled with the conduit for facilitating the actuation of the pump between a first pump position at which the container contents are drawn into the pump chamber and a second position at which the contents are expelled therefrom. The actuator is integrally molded so as to include a trigger, toggle and guides. The trigger is shiftable along an axis normal to the axis of the pump plunger which movement is facilitated by the guides. The toggle includes a substantially planar intermediate section that includes a hinge that permits the intermediate planar sections to fold the sections about the hinge towards one another whereby the transverse movement of the actuator is translated into reciprocal movement of the plunger and consequently actuation of the pump from its first pump position to its second position at which the container contents are expelled from the pump chamber. Release of the actuator permits the intermediate toggle sections to unfold away from one another by the hinge means to cause reverse reciprocation of the plunger and consequent actuation of the pump to its initial position at which the pump chamber is filled with the material to be pumped.
