A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.

A beverage dispensing valve may include an inlet to receive carbonated water, a nozzle shell, and an outlet downstream of the nozzle shell configured to dispense a finished beverage. The nozzle shell may include an aperture open to ambient pressure environment. A method for dispensing a beverage may include flowing carbonated water through an inlet of a beverage dispensing valve, lowering the pressure of the carbonated water sufficient to promote carbon dioxide nucleation, flowing the carbonated water through a chamber vented to environment such that a portion of carbon dioxide nucleated is off-gassed, and introducing a beverage ingredient when the carbonated water reaches a sufficiently low carbonation level. A beverage dispensing nozzle may include an inlet configured to receive carbonated water from a beverage dispensing valve, a nozzle shell including an aperture open to ambient pressure environment, and an outlet downstream of the nozzle shell configured to dispense a finished beverage.

An appliance for the production and dispensing of malt based fermented beverage has a malt based fermented beverage concentrated inlet, liquid lines, a water inlet, a pressurized gas inlet, a carbonation unit having a water inlet and a pressurized gas inlet, a mixing unit in which the carbonated water and malt based fermented beverage concentrate are mixed. The appliance further has a gas pressure regulating means for varying the gas at the inlet of the carbonation unit.

A system for regulating pressure within a beverage container. A high-side cartridge assembly includes a cartridge shell enclosing a high-pressure cavity, a piercing tip to puncture a pressurized-gas container, a high-pressure passage extending through the piercing tip and to the high-pressure cavity, and a piston to intermittently open the high-pressure cavity to a low-pressure cavity external to the high-side cartridge assembly. The low-side cap assembly includes a cap body having a socket configured to receive the high-side cartridge assembly, and no part of the cap body forms a boundary of the high-pressure cavity. Also disclosed is an interface having a housing, a tap assembly, a dip tube, a carry handle, and a receiving section. The housing is configured to couple to a beverage container, and the receiving section is configured to receive a pressure regulator.

A pressure regulator valve adapted to be secured within a container housing a beverage to be dispensed through the aid of pressure within the headspace (11) above the beverage, the regulator valve includes a housing (16) containing a piston (26) having one surface exposed continuously to the pressure in the headspace and the other surface being engaged by a spring (44), a source of pressurized gas (14) such as carbon dioxide is secured to the housing and includes a valve (60) which is activated by the piston which moves responsive to a differential between the spring force and the headspace pressure to open the valve (60) when the headspace pressure falls below a predetermined level to insert the carbon dioxide into the headspace to maintain the headspace pressure sufficient to dispense the beverage.

The present application provides a beverage dispensing system for naturally carbonated beverages. The beverage dispensing system may include a cabinet with a cooling element and a heating element and a fermentation vessel positioned within the cabinet. The cooling element and the heating element maintain the fermentation vessel within a temperature range for a fermentation process therein and the cooling element cools the fermentation vessel to stop the fermentation process.

A system comprising, a pressurized container including hollow portion and outer portion, pressurized container maintains pressure level in the hollow portion, transport system including two conduits, one transport being coupled to an interface and a valve port, the interface coupled to the hollow portion, the interface maintains pressure level in the hollow portion, one valve port allows flow of liquid volume through one conduit to a dispensing interface via another valve port, an external container is airtight and operable to dispense another liquid volume stored within, another conduit is coupled to the external container and further valve port to refill the liquid volume via the valve, pressure regulation system connected to pressurized container, pressure regulation system including a pressure conduit extending from outer portion through a pressure interface, pressure regulation system operable to compress liquid volume in the environment and a control system controls the valve and pressure regulation system.

A shutoff valve system for dispensing beverage from an open source syrup tank is presented. The shutoff valve system includes a syrup inlet receiving syrup from the open source syrup tank and a syrup outlet dispensing the syrup to a pump. The shutoff valve also includes a water inlet receiving water, and a water outlet dispensing the water to a dispensing point. Two distinct inlets and outlets for syrup and water prevent the syrup and water being mixed in the shutoff valve. The shutoff valve system further includes an actuator rod that is configured to block the water outlet in response to a pressure change at the syrup inlet, where the pressure change is caused by air flow from the syrup inlet.

Containers are provided for use with a beverage dispensing device. The container can include a housing defining a hollow interior and having an inlet leading to the hollow interior therein, an outlet disposed on the housing and leading to the hollow interior, a tube extending from the inlet and through the hollow interior toward a wall of the housing opposite the inlet, and a valve disposed in the outlet.
