A liquid dispenser includes a housing configured to receive a liquid supply cartridge, and a reservoir disposed in the housing that holds a volume of the product. The reservoir includes an access port for receiving the liquid supply cartridge and placing the liquid supply cartridge and the reservoir in communication. A dosing tank is connected to the reservoir and configured to hold a metered volume of the product. A control valve is movable between an opened position and a closed position, wherein when the control valve is in the opened position, product in the dosing tank is permitted to flow from the liquid dispenser and product flow from the reservoir to the dosing tank is prevented, and when the control valve is in the closed position, product in the dosing tank is prevented from flowing from the liquid dispenser and product flow from the reservoir to the dosing tank is permitted.

A water dispenser is provided that includes an upper chamber for receiving liquid, a triptych-layer filtering assembly operably coupled to the upper chamber, a lower chamber operably coupled to the triptych-layer filtering assembly for dispensing filtered liquid, and a float assembly system. In one embodiment, the float assembly is operably coupled to the upper and lower chambers. The float assembly system may include a float body, a float valve and a float seal.

A refrigerator includes an outer case, an inner case configured to define a storage space, an insulation material between the outer case and the inner case, a tank provided inside the storage space to store liquid, a rear guide provided at a rear through which a supply tube configured to supply liquid to the tank passes, a dispenser provided inside of the storage space to dispense liquid from the tank, and a tube guide embedded in the insulation material between the inner case and the outer case to define a passage through which a discharge tube configured to connect the tank to the dispenser passes.

According to certain embodiments, a connector for dispensing a liquid from a container comprises a main body connectable to the container and a subassembly being movable relative to the main body between an inactivated position and an activated position. The subassembly comprises inner and outer hollow piercing members. When the main body is connected to the container and the subassembly is moved from the inactivated position to the activated position, the inner hollow piercing member is arranged to pierce a seal of an inner cavity of the container, and the outer piercing member is arranged to pierce a seal of an outer cavity of the container.

A refrigerator includes an outer case, an inner case configured to define a storage space, an insulation material between the outer case and the inner case, a tank provided inside the storage space to store liquid, a rear guide provided at a rear through which a supply tube configured to supply liquid to the tank passes, a dispenser provided inside of the storage space to dispense liquid from the tank, and a tube guide embedded in the insulation material between the inner case and the outer case to define a passage through which a discharge tube configured to connect the tank to the dispenser passes.

There is described a wine supply system. The wine supply system generally has a tank in a source building, the tank containing wine; a plurality of ducts extending between the tank and a corresponding plurality of dispensing buildings remote from the source building and from one another, at least some wine being forcingly guided from the tank to the dispensing buildings via the plurality of ducts; and a temperature maintaining device disposed along the plurality of ducts outside of the source building and the plurality of dispensing buildings, the temperature maintaining device configured for at least one of heating and cooling said ducts to maintain the wine within a given temperature range.

Systems and methods for the injection/dispensing of fluid material in a volumetrically accurate and repeatable manner via an injection cell that interconnects two reservoirs of the fluid material. The injection cell has a normally closed dispensing valve that is opened for dispensing of the fluid material during a compression cycle, and closed during a return cycle. Opening and closing of the dispensing valve is effected using either or both of pressurized air and/or a motorized linkage. During the compression cycle, independent longitudinal displacements of a piston cylinder and a piston within the injection cell act to first open the dispensing valve and subsequently eject fluid material within the piston cylinder via the opened dispensing valve. The piston cylinder and piston are returned to an initial state that facilitates reloading of the injection cell from the reservoirs and closes the dispensing valve during a return cycle.

Disclosed is a compact system, apparatus for beverage preservation and dispensation. The system and apparatus may include a seal for attachment to a beverage container; at least a first conduit and a second conduit arranged to provide filtered air and extract beverage from the beverage container. There is a pump assembly connected to the first conduit and the second conduit to regulate air flow into and/or out of the beverage container to achieve a sub-atmospheric pressure or a super-atmospheric pressure within the beverage container.

A fluid storage and dispensing system that safely and efficiently stores all grades of motor oil is provided. The system is configured to accurately dispense motor oil into vehicles. The system may also be used for the storage of and dispensing of other fluids.

A method and apparatus of sanitizing drinking water to be dispensed from a water dispenser having a reservoir includes the steps of providing the ozone gas generator that generates an ozone gas stream, transmitting the ozone gas stream from the generator to the water dispenser reservoir, mechanically breaking up the ozone gas stream inside the reservoir to produce ozone gas bubbles, and using the ozone gas bubbles to disinfect water in the reservoir. The ozone gas stream can be mechanically broken up using a pump such as, for example, an impeller type pump.
