Abstract
Liquid is supplied from a bottle B to a discharge outlet 8 via a molded plastics reservoir 15 by pressurizing the bottle using an air pump 22. A pressure sensor responds to a rise in air pressure supplied to the bottle by shutting off the pump. Liquid is removed from the reservoir through a dip tube 17 having a main outlet 18 adjacent to the bottom of the reservoir and a smaller auxiliary outlet 21 adjacent to the top of the reservoir. The upper region of the reservoir is received in a finned heat-conducting holder 16 provided with a thermoelectric cooling element. For hygienic purposes the bottle has a connector 12 which can be replaced together with the reservoir 15 and associated supply tubes 24, 13, 14, 17 and 19. A temperature-control mixer 51 may be to mix liquid from the reservoir with liquid from the bottle.
