An apparatus for preventing the formation of beer stones and a gas-induced phenomenon, in which foamy beer spurts out of a draught beer container, is disposed in a pipe between the draught beer container and a draught beer dispensing apparatus so as to prevent the gas-induced phenomenon from occurring when the beer is discharged from the draught beer container to the draught beer dispensing apparatus, and to remove and prevent the formation of beer stones deposited on the inner surface of the pipe, between the draught beer container and the draught beer dispensing apparatus, or on the inner surface of the draught beer dispensing apparatus.

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.

Disclosed are exemplary embodiments of apparatus, systems and methods relating to transfer of fluids to/from containers and/or storage/transport of fluids in containers. In an exemplary embodiment, an apparatus comprises a container including a fitment having an opening. The apparatus may include a valve within the fitment. The valve may be configured to inhibit fluid flow out of the container. The apparatus may also include a transfer tube configured to be positioned through the opening of the fitment. The transfer tube may engage and open the valve to thereby provide an open passage to/from the container.

A portable beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A gauge, such as a pressure and/or temperature gauge provides feedback about characteristics of the beverage contained within the dispenser.

A container for a fluid under pressure, preferably a beer keg, including a neck and a fitting mounted thereon with a suction tube for drawing the fluid into the container. A pressure relief valve is mounted in an upper end of the suction tube or in the neck of the container. The pressure relief valve includes a closing body which is mounted resiliently via a spring and movable from a closing position to an open position by the spring being compressed.

A beverage dispenser includes a vessel, a dispensing tap, a dispenser assembly, and a dispensing tube. The vessel defines an internal volume, a lower opening, and an upper opening. The dispensing tube couples the dispensing tap to the dispenser assembly. The dispenser assembly includes a liquid level gauge structure (gauge structure), a riser tube, a lower housing, and an upper housing. The riser tube is positioned within a gauge structure and defines a riser volume. A gauge volume is defined between the gauge structure and the riser tube. The lower housing is configured such that the riser volume and the gauge volume are in fluid communication with the internal volume. The upper housing is configured such that the internal volume is in fluid communication with only the gauge volume and the riser tube is in fluid communication with a volume defined by the dispensing tube.

A carbonation device (100) for carbonating a beverage in a container (200), the carbonation device (100) comprising: a head portion (114b) for sealably receiving a mouth portion (220) of the container (200), the head portion (114b) having an infuser (120) that is operable to inject carbon dioxide into the container (200) via the mouth (220) of the container (200); and an engagement feature (173) with which the container (200) can be configured to securably locate the container (200) with respect to the head portion (114b) in: an injection configuration in which the mouth portion (220) of the container (200) is substantially sealed with respect to the infuser (120) so that the infuser (120) can inject carbon dioxide into the container (200) to carbonate the beverage in the container; and a depressurisation configuration in which the mouth portion (220) of the container (200) is partially unsealed with respect to the infuser (120) to allow for depressurization of the container (200).

A sensor coupled to a computer can sense a pressure of a buffer tank. A computer can determine a start of dispensing a beverage from a beverage dispenser. The computer can determine that an elapsed time from the start of dispensing the beverage reaches a predefined duration threshold. The computer can measure a particular pressure of the buffer tank when determining that the elapsed time reaches the predefined duration threshold. The computer can determine that the particular pressure falls below a predefined pressure threshold. The computer can generate an order to replace a water filter of the beverage dispense in response to the particular pressure at the elapsed time falling below the predefined pressure threshold.

Disclosed are a pressure regulator and a sparkling water machine. The pressure regulator includes: an arc flow path and a transiting chamber; a cross section of the arc flow path is configured to gradually increase from an input end of the arc flow path to an output end of the arc flow path, and the input end of the arc flow path is communicated with an inlet of the pressure regulator; and the transiting chamber is respectively communicated with the output end of the arc flow path and a discharging port of the pressure regulator.

The present disclosure discloses a fluid pulse damper. It comprises a damper body and a top cover, the top cover being combined with the damper body to define a closed chamber, with an inlet and an outlet into the closed chamber provided at opposite ends of the damper body; and a damper block, being provided on a bottom wall of the closed chamber, and being shaped so that fluid entering from the inlet is divided into a number of diffuse diversions and the diffuse diversions converge in proximity to the outlet and then flow out from the outlet. The disclosure also discloses a beverage preparation device including such a fluid pulse damper. The disclosure enables the fluid passing into the fluid pulse damper to diffuse into a plurality of symmetrically distributed diversions, so that the energy is dispersed in the diversions with different directions, and then converges in proximity of the outlet. The energies of the diversions in opposite directions cancel each other's at the time of convergence, to obtain a smoother fluid flowing out from thereof.
