ABSTRACT:
A self heating individual meal package includes a quantity of foodstuff to be heated. The package consists of a thermal insulated outer pouch. Within the package is an electrolytic-solvent activated exothermic-chemical pad or powder enclosed in an absorbent envelope, a bag containing electrolytic solvent and a pouch for foodstuff. The solvent bag is affixed to a board material which provides a rigid structure for the functioning of a tear filament pull-tab mechanism or the rupturing of the solvent bag. The pull-tab is affixed to the solvent bag so that when pulled the bag will open and the electrolytic solvent within can flow out to trigger the exothermic reaction.
