Abstract
A self-contained manually triggerable thermal energy pack includes a flexible enclosure containing a supercooled solution capable of being triggered to begin crystallization and a triggering structure including a single close turn helical metallic spring having sufficient stiffness to maintain its cylindrical shape and sufficient resiliency to allow bending by the application of manual pressure normal to its axis.
