A device is disclosed, for cooling a liquid, especially a beverage, comprising a cold accumulator and a thermal line, the cold accumulator and the liquid to be cooled being thermally connected by means of the thermal line, and the cold accumulator comprising a phase change material, the device also comprising means for dissipating heat from at least the thermal line, and the cold accumulator comprising a carrier material into which the phase change material is integrated.

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 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.

An effervescent liquid dispenser for a carbonated beverage is disclosed that includes a container containing liquid to be dispensed receiving pressurized gas from a pressurized gas source, becoming a pressurized liquid, the pressurized liquid becoming an effervescent liquid upon being dispensed from the container; and a dispense valve that is positionable in a first position for permitting pressurized gas to be received in a vessel to become the pressurized gas source, the dispense valve selectably movable between the first position and a second position, the dispense valve being secured to the container in the second position in response to the vessel receiving pressurized gas, the vessel becoming the pressurized gas source for the dispenser; wherein the container complies with 27 C.F.R. 5.46 (1999) and conforms with 49 C.F.R. 173.306 (1976)

An adapter having a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting a liquid to or from a container, by applying a load to the male coupling after inserting it into the female coupling, the load being provided by the weight of a portion of the external device, the adapter being configured for insertion in a mouth of the container and secured therein using a stretchable membrane that fits snugly around the mouth of the container for obtaining a tight seal, the stretchable membrane having tabs for a user to grasp.

A portable apparatus for mixing fluids comprising is provided, and has a housing, inlets for receiving a plurality of fluids at the housing, and a fluid mixer for receiving the fluids from the housing and mixing them. The fluid mixer outputs at least one fluid blend. A fluid blend selector then receives fluids from the inlets and at least one blend from the fluid mixer and outputs a selected fluid, where the selected fluid is one of the fluids from the inlets or one of the at least one fluid blends.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

Thorough mixing of nitrogen with a beverage to provide a visually interesting and tasty drink is achieved by passing the nitrogen and beverage together through a mixing manifold that is inexpensive to manufacture and easily cleaned and sanitized.

A beverage dispenser includes a gas infusion device configured to infuse a gas into a base liquid to form a gas-infused liquid, a mixing chamber configured to mix the gas-infused liquid and a concentrate to thereby form a reconstituted beverage, a first flow control configured to decrease pressure of the gas-infused liquid prior to mixing with the concentrate, and a second flow control configured to decrease pressure of the concentrate prior to mixing with the gas-infused liquid. A restrictor device downstream from the mixing chamber and configured to apply backpressure on the concentrate and the gas-infused liquid, and a dispensing valve is configured to dispense the reconstituted beverage.

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.
