<p>A self-heating receptacle is provided herein comprising a vessel for food to be heated, and below the vessel, a container sealed by a lid. The container contains two chemicals, e.g. quicklime and water, which are reagents for an exothermic reaction. A pouch within the container holds one of the chemicals sealed from the other. A flexible tearing filament secured to the pouch is for simultaneously opening both the pouch and the container, thereby to trigger the exothermic reaction to heat the food vessel. The tearing filament is so connected to the pouch and is so arranged that, upon pulling the tearing filament, the tearing filament creates a line of tear across both the pouch and the lid.</p> |
