A coupler device is arranged for bringing in fluid communication a beverage chamber of a beverage container and a beverage dispensing line. The coupler device comprises a housing with a coupling organ arranged for detachably coupling the housing to the beverage container. A beverage channel extends through the housing between a beverage inlet and a beverage outlet, the beverage inlet configured for connecting a first dispensing line part of the beverage dispensing line and the beverage outlet configured for connecting a second dispensing line part of the beverage dispensing line. A broach element is movably arranged relative to the housing for broaching the beverage container to bring the beverage chamber in fluid communication with the first dispensing line part. The coupler housing comprises a cover movably arranged to move between an open position in which the cover enables access to the beverage inlet for connecting the first dispensing line part and a closed position in which the cover prevents a connecting of the first dispensing line part to the beverage inlet. The coupler device further comprises securing means configured for securing the cover in the closed position.

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 beverage dispensing assembly comprises a beverage container for containing a beverage, the container body comprising a beverage outlet provided with a beverage container sealing member arranged to enable opening of the beverage outlet. A beverage dispensing line extends between the beverage container and a dispenser for dispensing the beverage at a dispensing outlet of the dispenser. A coupler device is detachable coupled to the container body and coupled to a second beverage conduit of the beverage dispensing line, with a first beverage conduit of the beverage dispensing line extending between the beverage container and the coupler device. The first beverage conduit at a first end thereof comprises an adapter body fittingly arranged on the beverage container covering the beverage container sealing member. A piston is movably arranged in the coupler device for acting on the adapter body that is configured to open the beverage container sealing member upon actuation by the piston causing the beverage container sealing member to open the beverage outlet to provide a fluid connection between the beverage chamber and the first beverage conduit.

Disclosed is a beverage dispense system comprising a beverage flow path along which beverage flows in use from a beverage supply to a dispense site and a coolant flow path along which coolant flows from a cooler. The system further comprises a connector at an upstream end of the beverage flow path configured for releasable connection to the beverage supply. The connector comprises a beverage passage along which a portion of the beverage flow path extends and a coolant passage along which a portion of the coolant flow path extends. The system further comprises a sensor comprising two spaced probes arranged so as to be in contact with beverage flowing through the beverage passage in use to measure a parameter of the beverage, and a flexible tube-in-tube conduit extending from the connector. The conduit comprises an inner beverage tube extending within an outer coolant tube. The beverage tube is connected to the beverage passage so as to define a portion of the beverage flow path and the coolant tube is connected to the coolant passage so as to define a portion of the coolant flow path.

A fitting assembly for a beverage keg, the fitting assembly including a fitting housing having a resilient riser pipe that is located therein and is movable relative thereto; and a seal, wherein an electronic data carrier is located on or in the seal and/or in a cover for the seal.
