A liquid dispensing device includes a liquid extraction system that extracts a liquid from a container. The liquid dispensing device includes an identification system that identifies a type of the liquid. The liquid dispensing device includes a liquid preservation system that prevents degradation of the liquid. The liquid may be wine or other liquids.

A container whose content can be removed easily by a consumer. The container should be inexpensive to produce while being extremely easy to operate by the consumer, should provide a high degree of flexibility with respect to the choice of the propellant gas (pressure and type of gas) and should achieve a long storage life for the contents, even after the container has been tapped. The container comprises a fill chamber (40), a pressure chamber (6) and a pressure valve (10). The fill chamber (40) is formed by a container base (2), a container wall (7) and a container upper face (8), and a first pressure (p.sub.B) prevails in the fill chamber (40). The pressure chamber (6) is formed by the container base (2) and a pressure chamber base (5) and a second pressure (p.sub.D) prevails in the pressure chamber (6). The pressure valve (10) is connected to the container base (2) and the pressure chamber base (5). The pressure valve (10), when open, establishes fluid communication between the fill chamber (40) and the pressure chamber (6), and the pressure valve (10), is when closed, separates the fill chamber (40) and the pressure chamber (6) in a fluid-tight manner from one another.

A liquid dispensing device includes a needle. The needle is adapted to penetrate a container without tearing out a portion of the container. The portion of the container is near a point of penetration on the container. The liquid dispensing device includes a motion control system. The motion control system is configured to rotate the needle while the needle penetrates the container.

The present invention provides a beverage preservation keg with an adjustable beer tap, including a shell, an inner container, and a gas-liquid control device; the inner container includes an upper gas storage chamber and a lower beer storage chamber; the gas-liquid control device includes a keg spear, a dispenser and a beer discharge pipe; the keg spear matches and communicates with the gas storage chamber and the beer storage chamber, and the top end of the keg spear matches and is connected to the dispenser; the dispenser is connected to the matching beer discharge pipe. The present invention has the function of adjusting the beer flow rate, and the keg spear is provided with a pressure relief valve, which eliminates the need for a gas tube and a separate pressure relief valve to connect the keg spear to the gas storage chamber in series.

The present invention discloses a beer spear with a pressure relief valve, which comprises a beer spear seat, a pressure relief valve, an inner tube fixing sleeve, an inner tube fixing spring and an inner tube assembly; the pressure relief valve is arranged on the outer side of the beer spear seat and the pressure inlet of the pressure relief valve communicates with a gas storage chamber; a head movable hole matching the head of a dispenser is opened at the top of the beer spear seat. The present invention is more convenient to assemble and disassemble a draft beer keg, and also the space for the draft beer keg is saved and the problems such as gas leakage and draft beer spoiling caused by damages of the gas tube are avoided.

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.

Beverage dispensing assembly (1), comprising a dispenser (2) and a beverage container (3), wherein the beverage container (3) has a neck portion (7) and a shoulder portion (8) adjacent the neck portion (7), wherein the neck portion (7) is provided with at least an outflow opening and at least one gas inlet opening (9) and wherein the dispenser (2) comprises a housing (4), wherein the housing (4) is provided with a receptacle (5) for receiving at least part of the container (3), wherein the container (3) is positioned in the dispenser (2) with the neck and shoulder portion (7, 8) facing downward, such that the neck portion (7) and at least part of the shoulder portion (8) are received in the receptacle (5), wherein part of the shoulder portion (8) extends close to and/or is in contact with a wall of the receptacle (5), wherein preferably a lid (12) is provided over the container (3), enclosing a part of the container (3) extending outside the receptacle (5).

A liquid dispenser comprise a nozzle comprising an inlet in fluid communication with an outlet to form a flow path, a thermistor in fluid communication with the inlet, an actuator rod comprising a gasket rod tip viton, at least one centering pin to center the actuator rod in at least a portion of the flow path, a flowmeter in fluid communication with the inlet, a double acting pneumatic cylinder comprising a first pneumatic inlet and a second pneumatic inlet operatively connected to the actuator rod, and a switch lever operatively coupled to a micro switch, wherein the nozzle opens when gas enters the first pneumatic inlet when the switch lever is activated by pressing on the micro switch and closes when gas enters the second pneumatic inlet when the switch lever is deactivated. Portable and non-portable liquid dispensing systems comprising the liquid dispenser are also described.

A beverage maker includes: a container; a fermentation tank; a beverage dispenser including a lever configured to control dispensing of the beverage and a limit switch configured to be turned on and off based on manipulation of the lever; a beverage dispensing channel that connects the container and the beverage dispenser and that guides the beverage; a beverage dispensing valve disposed in the beverage dispensing channel; a pressure sensor that measures gas pressure inside the container; and a controller. The controller detects whether the limit switch is turned on, opens the beverage dispensing valve to dispense the beverage accommodated in the container through the beverage dispenser based on detecting that the limit switch is turned on, determines a gas pressure value corresponding to the gas pressure inside the container measured by the pressure sensor, and determines a dispensed amount of beverage based on the gas pressure value.

The present invention provides a beverage preservation keg with an adjustable beer tap, including a shell, an inner container, and a gas-liquid control device; the inner container includes an upper gas storage chamber and a lower beer storage chamber; the gas-liquid control device includes a keg spear, a dispenser and a beer discharge pipe; the keg spear matches and communicates with the gas storage chamber and the beer storage chamber, and the top end of the keg spear matches and is connected to the dispenser; the dispenser is connected to the matching beer discharge pipe. The present invention has the function of adjusting the beer flow rate, and the keg spear is provided with a pressure relief valve, which eliminates the need for a gas tube and a separate pressure relief valve to connect the keg spear to the gas storage chamber in series.
