Abstract: The apparatus includes a reservoir (2), a liquid source (1), a carbon dioxide source (12), a non-return valve (8), a carbonating vessel (7) to receive liquid from the reservoir (2) via the non-return valve (8), a gas inlet (15) to receive carbon dioxide from the carbon dioxide source (12), and a dip tube (16) to withdraw carbonated liquid from the carbonating vessel. A pressure relief valve (20) vents gas from the carbonating vessel (7), and a dispense valve (18) controls the supply of carbonated liquid from the dip tube (16) to a dispense outlet (17). A charge control valve (14) controls the supply of carbon dioxide to the carbonating vessel (7).

Abstract: The apparatus includes a housing having a dispensing location for liquid disposed above a repository for a liquid storage container. A pressurising assembly including an air pump supplies gas to pressurize the container and cause liquid to leave the container via a delivery tube. A replaceable flow assembly including a manifold 30 and a reservoir 18 conveys liquid from the delivery tube 16 to the reservoir and thence from the reservoir 18 to the dispensing location. The manifold has an underside which includes a riser tube connector 36 and a reservoir connector 40 to rigidly mount the manifold on the reservoir. An upper side of the manifold has an outlet 33 located directly above the reservoir connector 40. The manifold contains a chamber 58 configured to convey liquid from the riser tube connector 36 to the reservoir 18 and a connector 37 for feeding a second reservoir provided with a steam venting valve.

Abstract: A replaceable flow assembly for use in a water cooler or similar bottled liquid dispenser includes a liquid reservoir 7 and a manifold 48 incorporating a bottle connector 5, 49 for releasable sealing engagement with a neck formed on an inverted bottle. The manifold is mounted on the reservoir and incorporates a first pathway for conducting liquid from a feed tube 5 to the reservoir 7, and a second pathway for conducting liquid from the reservoir to a discharge outlet 53. A third pathway within the manifold conducts atmospheric air through an air filter 28 and into the interior of the bottle through the feed tube 5 without passing through the reservoir 7. The manifold preferably also incorporates a dispense valve between the reservoir 7 and the discharge outlet 53 (e.g. in arm 52), which co-operates with a fixed valve-operating member within the dispenser.

Abstract: A thermally-insulated reservoir 9 for a dispenser in which liquid is supplied from a bottle to a discharge outlet via a reservoir, has an inner wall 23 and an outer wall 24 defining a sealed and evacuated heat-insulating cavity 30 at least partially surrounding a liquid space 22. In one application of the invention the reservoir takes the form of a cooling vessel with the thermal means provided by a cooling coil 26. The invention may also be applied to reservoirs which form a hot tank with the thermal means provided by an electrical heating element.

Abstract: A water cooler has a vertically elongate housing 1 with a dispensing recess 8 and a vertically elongate opening 10 located below the dispensing recess to receive a bottle of water 11. The bottle is supported on a fixed platform 18 which projects forward beyond the sides 15 and 16 of the opening for ease of loading. Liquid is removed from the bottle through an inclined dip tube which is raised and lowered by a lead screw and follower. The dip tube may be inserted through a probe which operates a bottle opening mechanism.
