Abstract

Ambient liquid is supplied from a bottle to a reservoir (3) which is surrounded by cooling coils (44) within a heat-insulating receptacle (40). Chilled liquid may be drawn off from the bottle and dispensed through a discharge outlet. The reservoir (3) also supplies chilled liquid to a pressurised oxygenating vessel (12) and a pressurised carbonating vessel (22) for supplying chilled and gassed liquid to respective discharge outlets. The coils (44) provide a heat exchange cooling surface which surrounds the reservoir (3) and the pressure vessels (12, 22), and the reservoir is in mutual heat exchange contact with the two pressure vessels such that there is greater heat transfer between the reservoir and the pressure vessels than there is between each of the pressure vessels and the cooling coils (44). The arrangement results in reduced manufacturing cost with fewer internal components and reduced internal volume without risk of damage through freezing of the pressure vessels when ambient liquid enters the reservoir (3).
