Abstract:
1. A pump attachment for a container comprising: a body having a first end and a second end and defining a chamber formed in part by a interior wall extending between the first end and the second end; a shaft extending into the chamber through an opening in the first end of the body; a piston reciprocally mounted within the chamber and coupled to the shaft, the piston including an upper surface and a lower surface, the piston being in sealing engagement with the interior wall of the body, the piston separating the chamber into an upper portion above the upper surface of the piston and a lower portion below the lower surface of the piston; a handle coupled to the piston through the shaft; an inlet valve at the second end of the body, the inlet valve configured to permit the flow of fluid into the chamber and restrict the flow of fluid out of the chamber; a biasing member within the chamber between the piston and the first end of the body, and an outlet passage at the second end of the body; a conduit in fluid communication with the outlet passage; a spray nozzle that comprises an actuator and a discharge outlet, the actuator being coupled to a spray valve for controlling the flow of chemical from the conduit through the spray nozzle to the discharge outlet, the spray nozzle being rigidly coupled to the container while the discharge outlet defines a spray pattern; wherein the spray nozzle includes a flexible tube that is in fluid communication with the conduit and that extends continuously from a point upstream of the spray valve to a point downstream of the spray valve and wherein when the actuator is in a first position the tubing passes through the valve substantially unobstructed and in a second position the tubing is pinched closed within the valve.
