摘要: 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.

摘要: A self cooling can has water on a pre-wetted wick (478), in a chamber and an adsorbent in another chamber communicable upon actuation of the can with the chamber. One or both of the chambers is at low pressure. Upon actuation the pressure of the wick drops, water vapour is absorbed by the adsorbent from the internal atmosphere and more water evaporates from the wick to replace it, thereby causing a cooling effect in heat generated in the adsorbent may be contained by but a take-up system, such as phase change material or microcapsules of high heat capacity material such as water.
