The dispenser is a rigid type multi-chamber, refillable dispenser where only the substance containing chambers need to be discarded and replaced. At the point of the chambers interconnecting into the upper portion of the dispensers there is a cutter to break the seal on the chambers. In operation stabilized piston rods fit into each chamber and push against pistons having a deformable upper surface to expel the substance. The refill chambers have off-center exit openings whereby the distance to the dispenser nozzle exit is minimized. The push rods are stabilized by being of a size and shape to be proximate the walls of the chambers while actuating the pistons.
