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.
A bottled liquid dispenser in which liquid is supplied from a bottle to a discharge outlet via a reservoir, wherein the dispenser includes means for holding the bottle, a bottle connector for releasable sealing engagement with a neck formed at the top of the bottle, the bottle connector being provided with an air inlet for supplying air to an upper region of the bottle, a dip tube for removing liquid from a lower region of the bottle, and a transfer tube for supplying liquid to the reservoir, thermal means which snugly receives the reservoir with a minimal intervening gap for controlling the temperature of liquid in the reservoir, and an outlet tube for conducting liquid from the reservoir to a discharge outlet, wherein the reservoir is removably received within the thermal means such that, for hygiene purposes, the reservoir and the bottle connector can be removed together with associated tubes and replaced with clean components.
A bottled liquid dispenser in which liquid is supplied from a bottle to a discharge outlet via a reservoir, wherein the dispenser includes means for holding the bottle, a bottle connector for releasable sealing engagement with a neck formed at the top of the bottle, the bottle connector being provided with an air inlet for supplying air to an upper region of the bottle, a dip tube for removing liquid from a lower region of the bottle, and a transfer tube for supplying liquid to the reservoir, thermal means for controlling the temperature of liquid in the reservoir, and an outlet tube for conducting liquid from the reservoir to a discharge outlet, wherein the reservoir is removably received within the thermal means such that, for hygiene purposes, the reservoir and the bottle connector can be removed together with associated tubes and replaced with clean components, wherein the reservoir is pre-formed for removable reception in a heat-conducting holder which embraces an upper region of the reservoir and said holder includes thermoelectric means for controlling the temperature of liquid in the reservoir, and wherein the thermal means includes a peltier element.
A bottled liquid dispenser in which liquid is supplied from a bottle to a discharge outlet via a reservoir, and said dispenser includes thermal means for controlling the temperature of liquid in the reservoir, and mixer means for mixing liquid from the reservoir with liquid from the bottle to supply said discharge outlet.
