A hand holdable pump spray system where the pump mechanism is in the hand holdable wand rather than in the liquid container. The wand may be held with one hand while the pump handle is extended with the other hand. This creates a pressure differential which allows liquid to flow from the container into the wand. A biased spring provides force against the liquid so that when a thumb actuated trigger opens the nozzle, the liquid will be ejected. Should all of the liquid not be ejected, there is a liquid return mechanism which opens a check valve and allows the liquid to return to the container through a supply tube connecting the wand and the container. |
