ABSTRACT A cartridge assembly for a caulking gun or similar dispenser contains two or more components to be mixed upon operation of the gun. One component is stored within an inner tubular container with flexible walls, which walls are sustained against collapse by a light gauge spiral spring extending between the nozzle end and the plunger end of the cartridge. The cartridge may have a rigid cylindrical outer tube within which the second component is retained by a plunger, or a flexible tubular outer container for the second component, again supported against collapse by a spring. A passive mixer unit is provided at the nozzle end of the assembly either inside or outside the body. The mixer unit is preferably cylind- rical, defining internally a double spiral mixing passage containing passive mixer elements.
