Stereo dispensing container and system
First Claim
1. A stereo dispensing container from which first and second materials are simultaneously dispensed, said container comprising:
- a caulking tube including a hollow cylindrical body having proximal and distal ends, an interior side wall extending longitudinally through said body between said proximal and distal ends, and a sealed spout connected to and projecting outwardly from said distal end;
a reservoir located within said body for holding a first of the materials to be dispensed, said reservoir and said spout lying in fluid communication with one another;
a flexible blister enclosure for holding the second of the materials to be dispensed, said blister enclosure affixed along the interior side wall of said body between the proximal and distal ends thereof;
a sealed outlet tube lying in fluid communication with said blister enclosure at the distal end of said body, said outlet tube surrounded by said spout so that cutting open said spout simultaneously opens said outlet tube; and
a caulking tube plunger located at the proximal end of said body and moving distally therethrough to ride over and compress said flexible blister enclosure for simultaneously expulsing the first material from said reservoir by way of said spout and said second material from said flexible blister by way of said outlet tube and mixing said first and second materials together.

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.
