A disposable container which has the ability to independently cool or heat a liquid beverage or food product by way of an endothermic or exothermic reaction. The container is disposable and has a double walled configuration to create a chamber therebetween. Within the chamber is a chemical compound which when activated provides the desired reaction upon the contents within the container. Thus, there is no requirement that this device must be subjected to external refrigeration or heat.

1. A container comprising:a double-walled container having an inner wall and an outer wall defining a interior portion for the reception of desired contents and a fully enclosed chamber located between said inner wall and said outer wall; and a plurality of rupturable pouches located within said fully enclosed chamber, wherein each of said plurality of rupturable pouches contains a component wherein when said rupturable pouches rupture the components contained therein mix together and produce a chemical reaction and wherein at least one of said plurality of rupturable pouches has a first chemical component contained therein and at least one of said plurality of rupturable pouches has a second chemical component contained therein and at least one of said plurality of rupturable pouches has a solvent contained therein and wherein said first and second chemical and said solvent mutually react with each other to produce heat or cold. 2. The container of claim 1 wherein said chemical reaction is an exothermic reaction.3. The container of claim 1 wherein said chemical components are selected from the group consisting of ammonium nitrate, ammonium sulfamate, ammonium iodide, ammonium bromide, sodium chloride, sodium nitrate, sodium nitrite, sodium carbonate, sodium bicarbonate, potassium nitrate, potassium nitrite, urea, methylurea, water and combinations thereof.4. The container of claim 1 wherein said first chemical and second chemical are selected from the group consisting of ammonium nitrate, ammonium sulfamate, ammonium iodide, ammonium bromide, sodium chloride, sodium nitrate, sodium nitrite, sodium carbonate, sodium bicarbonate, potassium nitrate, potassium nitrite, urea, methylurea, and combinations thereof, said first chemical and said second chemical being different.5. The container of claim 1 wherein said solvent is water.6. The container of claim 1 wherein said plurality of rupturable pouches rupture due to the squeezing of the walls of said double-walled container.7. The container of claim 1 further comprising a protective layer attached to the exterior of said outer wall of said double-walled container.8. The container of claim 7 wherein said protective layer is a series of air inflated pouches.
