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.

A dispensing apparatus for multi-component foam reactants in two pressurized containers, each said container including a projecting dispensing valve in the top end thereof, comprising: two parallel brackets for holding the top end and the base end of said two containers in a side-by-side fixed position, each bracket having a medial bore therethrough; a T-shaped member having a projecting medial sleeve with a bore therethrough and laterally extending rigid side bars for engagement with said container valves; a length of flexible tubing connected to each of said container valves and extending from one of said rigid side bars to a dispensing nozzle; a manual means for controlling the flow of foam reactants through said lengths of flexible tubing when said container valves are open; a manual key having an elongated shank extending coaxially within said bracket medial bores and said T-shaped member sleeve bore; and thread means having an internal component on said key shank and an external component in one of said bores whereby manual rotation of said key will move said T-shaped member toward one of said brackets to open said container valves in unison.
