A drinking vesselin which a beverage, for example a draught beer, is to be served is cooled by formation thereon of ice formed of frozen potable liquid for example a small volume of the same beer. The potable liquid can be sprayed atonto the insideof the vesseland/or onto the outsideof the vessel, and the liquid is then frozen on the vessel wall by the effect of a cooling coilsurrounding the vessel which can be rotated by a rotatably driven platform. The cooled vesselwill in turn cool beverage dispensed into it for drinking.

Cooling a drinking vessel

A beverage, for example a draught beverage, which may already be cooled before introduction into a drinking vessel is introduced into the vessel into which additional cooled material is introduced. The cooled material may be frozen water which is used to dilute the beverage to a desired strength e.g. a desired alcoholic strength. Alternatively the cooled material may be frozen beverage.

Dispensing a beverage

Apparatus for dispensing beverage, such as beer, which forms a head, comprises a rotatable table on which a drinking vessel is supported, and a nozzle which is arranged to direct a stream of beverage against the side of the vessel as it rotates. This provides good control over the size of the head produced. Various parameters, such as the temperature of the beverage can be monitored during the dispense, and the apparatus controlled, by adjusting the rate of rotation of the table, the rate of dispense of the beverage, or the angle at which the beverage impacts the side of the vessel, so as to produce a desired amount of head on the dispensed beverage.

Beverage dispense

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).

Relating to containers

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.
