A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

The present disclosure discloses a portable carbon dioxide adapter system. The system includes a first collar assembly for connecting to a liquid carbon dioxide source; a gasifying/flow adjusting assembly that converts liquid carbon dioxide into gaseous carbon dioxide and may adjust gas flow; an injection nozzle valve assembly that abuts against a gas inflow valve of a gas-injection-by-adapter object so as to inject the gaseous carbon dioxide; and a second collar assembly with one end slidably receiving the injection nozzle valve assembly and the other end being securely connected to the gasifying/flow adjusting assembly. The liquid carbon dioxide source is a disposable carbon dioxide gas cylinder, and an opening unit for piecing the disposable carbon dioxide gas cylinder is mounted within the first collar assembly; and the gasifying/flow adjusting assembly has a volume-adjustable hollow inner cavity configuration.

A receiving apparatus for receiving a gas cartridge for a carbonation machine, the receiving apparatus includes a pressure chamber in which an overpressure is generated; with aid of the overpressure generated in the pressure chamber: i) a seal means is configured to be pressed onto the gas cartridge; and/or ii) the gas cartridge is configured to be fastened to the carbonation machine; the receiving apparatus includes: a pressure transmission means to press the seal means onto the gas cartridge by way of the overpressure generated in the pressure chamber during a carbonation operation; and a spring device configured to exert a force on the pressure transmission means.

A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

A valve comprising a first chamber (111) and a second chamber (112), wherein a movable member (204) is arranged to selectably bring the first and second chambers into and out of fluid communication with one another, the movable member arranged such that when in an open position wherein the first and second chambers are in fluid communication, gas at a first pressure in the first chamber provides a closing force to a first surface area (222) of the movable member to overcome an opening force provided by gas at a second pressure in the second chamber on a second surface area (223) of the movable member whereby the movable member moves to a closed position to isolate the first and second chambers, and further arranged wherein as the movable member moves to the closed position, the second surface area of the movable member exposed within the second chamber is reduced thus reducing the opening force provided by the gas at the second pressure and providing a bias towards the closed position.

A connecting device comprising, a piercing housing for receiving the neck of a gas cylinder with a top surface comprising a gas outlet the piercing housing is defined by an opening, side wall and a bottom wall a piercing member arranged in the piercing housing for piercing the gas outlet of the gas cylinder a container defining a space for retaining the gas cylinder a protection cap being provided in the piercing housing which encloses the piercing member partially and can be pushed axially relative to the piercing member, wherein the axial direction coincides with the axis of the gas cylinder, wherein a male portion is provided on the protection cap for connecting the protection cap with the neck of the gas cylinder on which a female portion is present, wherein the female portion has a corresponding shape for being inserted in the male portion, the male portion and the female portion are fitted with each other when a correct position is achieved so that after the fitting the both portions cannot be rotated relative to each other.

The present disclosure concerns a pressurized gas container, for example one containing carbon dioxide for use in a device or system for the preparation of a carbonated drink. The present disclosure also provides a plug that may be functionally integrated into the container and further provides a packaging with a plurality of such containers.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head
