Abstract
The invention relates to a self-heating, disposable heating pack utilizing an exothermic chemical reaction. Self-moderation of the heat pack is provided through the use of a preformed reversibly stiffenable gel that alters the rate of exothermic chemical reactions. A vaporizable solvent is used to adjust the gel stiffness. The heat pack can be used in heat transfer or ambient temperature conditions which differ from those anticipated as design conditions.
