ABSTRACT:
A heat pack including apparatus for triggering the crystallization of a supercooled salt solution in the heat pack, wherein the supercooled salt solution is sealed within a flexible package. The apparatus comprises a solid trigger device, and a packet having at least one wall. The solid trigger device and crystals of the salt of the supercooled salt solution are located in the packet and the packet is sealed to at least one of the walls of the flexible package. Thus, the packet is in intimate positional relationship with the supercooled salt solution. The solid trigger device is forced to pierce the packet and deliver salt crystals from the packet to the supercooled salt solution thereby triggering crystallization of the supercooled salt solution and producing heat.
