ABSTRACT:
A heat pack for supplying thermal energy to the wearer on immersion in cold water comprises a capsule in which water can be admitted. The capsule contains a heat generating agent arranged in a tablet having such a shape that a reactive surface is created which allows the agent to react exothermally with the water at a controlled reaction rate.
