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. A valve connector 47 connects the steam venting valve to an air passage 29 which travels through a lifting handle 46 to the reservoir 18 via the chamber 58. The flow assembly contains no check valves or bypass valves and is self-purging on replacement.

Apparatus for dispensing a liquid from a liquid storage container associated with the apparatus:

a housing having a dispensing location from which liquid from a liquid storage container is dispensed, and a repository to receive said liquid storage container;
a first reservoir disposed in the housing, the first reservoir being configured to receive a liquid from the liquid storage container before the liquid is dispensed from the dispensing location;
a second reservoir disposed in the housing, the second reservoir being configured to receive a liquid from the liquid storage container before the liquid is dispensed from the dispensing location, the second reservoir being provided with an automatic gas-venting valve;
a delivery tube to convey liquid from said liquid storage container;
a first transfer conduit to convey liquid from the first reservoir to the dispensing location;
a second transfer conduit to convey liquid from the second reservoir to the dispensing location;
a manifold operably connected to the delivery tube and the first and second reservoirs to convey liquid from said liquid storage container to both of said reservoirs, and operably connected to the first reservoir to convey liquid from the first reservoir towards said dispensing location via said first transfer conduit, said manifold having:
an inlet to admit liquid from the delivery tube to the manifold,
a first reservoir connector to rigidly mount the manifold on the first reservoir,
a second reservoir connector to connect the manifold to the second reservoir,
a valve connector for connection to the automatic gas-venting valve,
a pathway to convey liquid from the inlet to the first reservoir via said first reservoir connector and to the second reservoir via said second reservoir connector,
an outlet passage to convey liquid from the first reservoir towards the dispensing location via the first reservoir connector, and
an air passage configured to admit air from the automatic gas-venting valve to the first reservoir via the valve connector.
