<p>An improvement is provided in a self heating receptacle of the type having a food vessel for foods and at least two chemicals disposed adjacent to the food vessel that can react exothermically. The improvement comprises: a pouch containing one of those at least two chemicals; a drawer containing the pouch, the food vessel including an opening therein for accepting the drawer; a guiding ramp disposed on the side of the drawer; cutting means disposed inside of the opening for opening the pouch to permit the two chemicals to produce an exothermic reaction; and roller means operatively connected to the cutting means. On engagement of the guiding ramp on the roller means, the cutting means moves toward the pouch to open the pouch, thereby setting off the exothermic reaction.</p> |
