Abstract

A warming pack includes a container in the form of a pack, pouch, or bag in which reactants for an exothermic chemical reaction are distributed in one or more flexible matrixes that prevent them from shifting. The rate of the reaction is controlled and the reaction is thermally buffered in order that heat be produced at a constant rate.
