Abstract: A dispensing device (10) is detachably mountable atop a plurality of valved containers (12a, 12b) containing constituents under pressure which are dispensed upon actuation of the container valves (17). The dispensing device (10) comprises a mixing chamber (56) for mixing together the constituents dispensed form the containers (12a, 12b) to form a mixed product and for outputting the mixed product through plural outlet ports (64), an applicator (25) having a plurality of tines (76) at least some of which are hollow, the hollow tines (76) being in fluid communication with respective outlet ports (64) of the mixing chamber (56) for dispensing from distal ends thereof the mixed product, and an actuator (50) for simultaneously actuating the container valves (17).
