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.

The invention relates to a pressure control device for attachment in a pressurized fluid container separating a dispersible fluid compartment and a propellant compartment, comprising a partition wall provided with at least one passage opening; and a closing element attached to the partition wall moveable between a passage opening release position and a passage opening closing position. The invention also relates to a pressurized fluid container provided with a such pressure control device.
