A coil spring made of a shape memory alloy is seated within the container of 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.

In a dispenser having a container within which a body of material is stored; retainer means for maintaining the body of material within the container; and selectively actuated means for releasing the retainer means to permit displacement thereof causing discharge of the body of material from the container under a delivery pressure, the improvement residing in: shape-memory means for imparting said displacement to the retainer means, said shape-memory means having pseudoelastic properties preselected to exclusively regulate said delivery pressure during said displacement of the retainer means causing said discharge of the body of material.
