Abstract
A dispensing apparatus to deliver at point-of-use chemically reactive constituents or foam reactants in a predetermined volumetric ratio. The foam reactants are prepackaged within replaceable pressurized containers carried by the apparatus and having projecting dispensing valves connected to a manually actuated dispensing nozzle through flexible tubing. The apparatus includes brackets for holding the top and base of the containers in side-by-side fixed relation, a T-shaped member for actuating the dispensing valves in unison, and a manual key with an elongated shank extending through bores in the brackets and the T-shaped member. The key shank and the bores are selectively threaded to provide opening or closing movement of the container dispensing valves.
