Carbonator for producing carbonated beverage

A carbonator for producing carbonated beverage comprising:

• a first connector, for a gas-outlet of a CO2-container, and with a CO2-valve operable between a closed state and an open state in which CO2-gas may be introduced from the gas-outlet of the CO2-container into the CO2-valve;
• a second connector, for a mouth of a beverage container, and with a dissolver nozzle, for introducing CO2-gas into the beverage container, connected to the CO2-valve;
• a venting valve connected to the second connector and operable between a closed state and an open state in which excess CO2-gas may be led out from the beverage container through the venting valve;
• an operating mechanism configured to operate the CO2-valve and the venting valve between open and closed states;
• and
• a manipulator, coupled to the operating mechanism, for allowing a person to operate the operating mechanism between:
• a start mode in which the venting valve is open and the CO2-valve is closed, and
• an end mode in which the CO2-valve is open and the venting valve is closed,
• wherein the operating mechanism is configured to be set in an intermediate mode, between the start mode and the end mode in which both the venting valve and the CO2-valve are closed.
