ABSTRACT:
A dispensing gun to deliver at point-of-use chemically reactive constituents or foam reactants in a predetermined volumetric ratio. The foam reactants are pre-packaged within pressurized containers connected to the gun through supply tubing. The dispensing gun has as its principal components: a body with a barrel, bore and pistol grip; a squeezable trigger housed in the pistol grip; a reactant supply and mixing component adjacent the front end of the bore; a reciprocating valve rod within the bore actuated by the trigger; and a bias means normally closing supply ports in the reactant supply and mixing component, and moving the trigger rearwardly of the pistol grip.
