Abstract
A manually operated trigger sprayer that stores a quantity of pressurized liquid during the charge stroke of the trigger for subsequent release during the return stroke, is presented. The trigger sprayer is configured such that an appreciable volume of liquid is dispensed during both the charge and the return strokes of the trigger, creating a continuous discharge stream, for so long as the trigger is actuated. The present invention trigger sprayer also provides an all plastic construction by replacing the metal coil spring of prior art trigger sprayers with a U-shaped plastic spring located exterior to the pump housing thereby making the trigger sprayer well-suited for recycling.
