SELF-CONTAINED HOT MEAL ASSEMBLY WITH STEAM VENT

Abstract

A self-contained meal assembly comprises a heating bag, a food pouch, and a heating element. In operation, a heating element is placed along a bottom portion of a heating bag, a food pouch is placed inside proximate the heating element, a predetermined amount of water or other nonflammable aqueous liquid is added, and the heating bag is resealed thereby allowing an exothermic reaction to occur within the heating bag. One or more steam vents may be formed through a heating bag allow steam to discharge from the interior of the heating bag during operation. The configuration of the steam vent(s) allows a controlled release of high temperature steam from the heating bag as it circulates within the heating bag to the steam vent(s) at a safe discharge angle relative to the sides of the heating bag.
