Abstract: A reusable bag (10) made of materials, such as an FDA approved food-grade silicone, which may or may not include fillers, that can withstand the extreme temperatures used in the entire food preparation, cooking, and cleaning processes, including, but not limited to, storing, freezing, defrosting, marinating, baking, and washing for reuse. The bag (10) may be seamless and may have rounded corners and/or a rounded bottom (14), which allows for reversibility for the purpose of cleaning and prevents the accumulation of food, bacteria, or other contaminants thereby ensuring the safety and reusability of the invention. This bag may be closed and opened repeatedly by a sealing mechanism (12) that allows for an air and water tight seal.

Abstract: A heated food sachet (10), sealed on all sides, that may be filled with one or more condiments or other edible substances (11), that contains a heat pack (12), which may be filled with a supercooled solution (13) and that contains a trigger (14). This trigger comprises two parts. First, the trigger may be one or more breakable hollow capsules (FIG. 3) or one or more air pockets (FIG. 4) that may be attached or unattached to the heat pack. Secondly, the inner part of the capsule or air pocket may contain crystals or any other substance (15) that will start the solidification process of the supercooled solution when coming into contact with each other. The heat emitted by the reaction warms the condiments or other edible substances contained in the sachet.
