ABSTRACT:
A trigger to initiate crystallization of a supercooled aqueous salt solution of a heat pack, thereby liberating heat. The trigger, when activated, pierces the container, allowing the salt solution to contact salt crystals, and initiate crystallization of the solution. A seal over the trigger prevents the solution from leaking from the heat pack. Optionally, the heat pack contains a flexible foam rubber pad immersed in the salt solution in the container to prevent saddlebagging.
