Abstract
A self cooling beverage container or can. In one embodiment water (26) is maintained at low pressure such that the boiling point is reduced. The water (26) is caused to boil and the vapour to be absorbed by a desiccant. The boiling of the water (26) causes heat to be absorbed from the beverage. The desiccant may be carbon (28). The water (26) or carbon (28) (or other chemicals) in one embodiment are maintained within a blind bore (30) within the container. The water and carbon are separated by a burstable membrane (42).
