Abstract
A self cooling beverage container or can. Different embodiments of a self cooling can are shown including the use of an endothermic reaction perhaps between ammonium nitrate and water. In another embodiment a volatile liquid is evaporated. In another embodiment water is maintained in a low pressure environment and allowed to boil. The vapour which is produced from the boiling water is absorbed by a desiccant maintaining the boiling process. The cooling process may be initiated by the pressure release of a carbonated beverage can during opening of the can.
