Abstract
A reusable device for delivering a release of heat to an area such as a body portion. The device comprises a flexible, fluid-tight container holding a liquid which releases heat upon crystallization such as sodium acetate tetrahydrate. A trigger located within the container initiates the crystallization of the liquid to release the latent heat. The trigger comprises a plurality of rigid objects held within a receptacle located within the container. The receptacle is in fluid communication with the container so that the plurality of rigid objects are in contact with the liquid. The trigger initiates the crystallization of the liquid when pressure is applied to the plurality of rigid objects such as by squeezing the trigger between one's fingers.
