The invention relates to a domestic machine for dispensing beverage, comprising a removable water tank, a water filtration system, at least one circulation pump for moving the water to a dispensing point associated with a beverage capsule, the machine comprising a heating section comprising a heater configured to heat the water to be dispensed, a cooling section comprising a cooling device configured to cool the water to be dispensed, and a carbonating section comprising a carbonating device configured to dissolve CO.sub.2 in the water to be dispensed, the machine comprising a control panel for selecting a hot drink, a cold drink or a carbonated drink, by activating at least one of said sections.

A system for extracting a paste from a flexible pouch having a sealed nozzle includes an inflatable flexible enclosure adjacent to the pouch and an air compressor for controlling airflow into the flexible enclosure. The air compressor provides a first target pressure within the flexible enclosure, the first pressure resulting in a rupture of the sealed nozzle, and a second target pressure within the flexible enclosure. Further, the system includes a timer for measuring a target time for completing the extraction of the paste from the flexible pouch.

A hollow needle insertion structure used in a wine fresh-keeping device may be shown and described. A wine bottle installation chamber, where the wine bottle installation chamber is arranged in a containing chamber, and one end of the wine bottle installation chamber is matched with an exchange port, a wine sleeve, the wine sleeve is arranged in the wine bottle installation chamber, and a cooperating movement threads is provided between outer side wall of the wine sleeve and inner side wall of the wine bottle installation chamber; and a hollow needle, the hollow needle is matched with the wine bottle installation chamber; after the wine bottle is installed in the wine sleeve, the wine sleeve moves along the cooperating movement threads into the wine bottle installation chamber, and after contact with the hollow needle, the hollow needle is inserted into the wine bottle under the rotation of the wine sleeve.

A clamp of the dispensing device may include a container engagement surface arranged to engage and/or disengage the clamp from the container neck when the clamp is pushed downwardly or pulled upwardly relative to the container neck. The container engagement surface may include a surface with a lower portion that slopes upwardly and inwardly, and an upper portion that slopes upwardly and outwardly relative to the container neck and that moves the clamp radially outwardly and away from the container neck as the clamp is moved vertically relative to the container neck. A latch may maintain a body portion of the dispensing device in an upper position, preventing needle insertion, until a container is suitably engaged with the base portion of the device, e.g., by a clamp. Sensors may detect engagement of a container with the device and/or insertion of a needle into the container.

A wine taking device used in a wine fresh-keeping device may be shown and described. A first pipe, the first end of the first pipe is connected with the fresh-keeping gas storage tank, a first solenoid valve, a first end of the first solenoid valve is connected to a second end of the first pipe, a second pipe, the first end of the second pipe is connected to a second end of the first solenoid valve, a three-way valve, a first end of the three-way valve is connected to a second end of the second pipe, a second solenoid valve, a first end of the second solenoid valve is connected to a second end of the three-way valve, and a second end of the second solenoid valve is provided with a hollow needle used to reach into the wine bottle to take wine, and connected to the second solenoid valve.

A wine fresh-keeping device may be shown and described. The wine fresh-keeping device includes: a housing, and an exchange port for exchanging items inside and outside the housing, and a sealing cover is provided at the exchange port, a containing chamber is formed inside the housing, a fresh-keeping gas storage tank, and one end of the fresh-keeping gas storage tank is matched with the exchange port, a wine bottle installation chamber, the wine bottle installation chamber is arranged in the containing chamber, and one end of the wine bottle installation chamber is matched with the exchange port, a wine taking device, the wine taking device is arranged in the housing and connected to the fresh-keeping gas storage tank, and a refrigeration device, the refrigeration device is arranged on the housing, and cools the wine installation chamber.

The refillable drinking vessel comprises a bottle, a bottle fitting structure, a base plate, and a fluid control structure. The base plate forms a fluidic connection between the bottle fitting structure and a pressurized fluid source. The bottle fitting structure forms a fluidic connection between the bottle and the base plate. The fluid control structure automatically controls the flow of fluid from the pressurized fluid source through the base plate and the bottle fitting structure into the bottle. The fluid control structure senses when the bottle is near the base plate. The fluid control structure measures and controls the amount of fluid contained in the bottle.

Containers are provided and include a container body having an opening extending into a hollow interior, and a cap extending across the opening. The cap has an inlet port with an inlet valve configured to couple to a fluid source such that fluid can be delivered through the inlet valve to pressurized the hollow interior of the container body. The cap also has an outlet port with an outlet valve having a cracking pressure at which the outlet valve is configured to move from a closed configuration to an open configuration to dispense fluid from the hollow interior, and a closing pressure at which the outlet valve is configured to move from the open configuration to the closed configuration to prevent fluid from passing therethrough. The cracking pressure is greater than the closing pressure.

The invention relates to a cartridge system (1) for producing a drink in a drink preparation machine, comprising a cartridge (2) that has a reservoir (6) filed with a drink substance (7), and a cartridge receiver (10) that can be reversibly connected to the cartridge, said cartridge receiver (10) comprising a mixing chamber (8) and a cartridge discharge device (34) which causes at least partial transfer of the drink substance (7) from the reservoir (6) into the mixing chamber (8), and said cartridge receiver (10) comprising a fluid supply (12) which opens into the mixing chamber (8). The invention also relates to the cartridge receiver (10) of the cartridge system (1), the drink preparation machine, and the corresponding method for producing a drink (70).

Proposed is a cartridge system for making a beverage, the cartridge system being insertable into a beverage preparation machine and comprising: a cartridge that includes a reservoir filled with a beverage substance; and a cartridge receptacle that is connected to the cartridge; the cartridge receptacle includes a mixing chamber fluidically connectable to the reservoir, and a fluid feed line extending into the mixing chamber; the cartridge has a cartridge wall; characterized in that the cartridge wall includes a flange for attaching a sealing element.
