ABSTRACT:
A dispenser gun for selectively dispensing controlled quantities of viscous or semi-viscous materials, and in particular liquid pesticides or insecticides, employs a vacuum driven operating system for discharging and reloading the viscous or semi-viscous materials to be discharged. The dispenser gun is designed to create pressure differentials in adjoining chambers which, in conjunction with a cooperating valve system, enables the discharge of precisely metered quantities of material and prevents continued and undesired discharge or dripping from a discharge nozzle after a preselected quantity of material has been discharged from the dispenser gun. The handle of the device includes structure for pre-selecting one or more predetermined quantities of material to be discharged from the dispenser in repeatable sequences. The dispenser gun also includes structure for removably receiving a replaceable reservoir of viscous or semi-viscous material to be discharged from the gun.
