A coil spring made of a shape memory alloy is seated within the container a portable dispenser in a contracted condition under compressive stress maintained by the physical constraint of a pressure plate engaging a collapsible enclosure internally lining the dispenser container to isolate therein material to be dispensed. The pseudoelastic properties of the shape memory alloy are selected to exclusively regulate the storage and delivery pressures in order to accommodate different materials to be dispensed and control discharge thereof by the dispenser.
