Abstract
A low cost stereo dispensing container (e.g. a disposable caulking cartridge) from which two part fluid products may be simultaneously dispensed in predetermined proportions relative to one another. A first material (e.g. a catalyst) is stored within a flexible blister. The blister may be adhesively affixed to a side of the container. In the alternative, the blister may be extruded or injection molded along a side of the container during manufacture. The second material (e.g. a resin) is stored within a holding chamber formed in the container alongside the blister. A plunger is moved through the container to ride over and compress the blister and thereby cause the first material to be expulsed therefrom into a spout of the container. At the same time, the volume of the holding chamber is reduced to thereby cause the second material to be simultaneously expulsed therefrom into the spout.
