A pressure control device (8) for medium-containing containers (2) such as liquid or gas containers, which pressure control device comprises a pressure control chamber (25) with at least one movable wall part (22) for operating a mechanism for opening and/or closing a gas supply opening (27) of a ga
A pressure control device (8) for medium-containing containers (2) such as liquid or gas containers, which pressure control device comprises a pressure control chamber (25) with at least one movable wall part (22) for operating a mechanism for opening and/or closing a gas supply opening (27) of a gas holder, while a scavenger (31) is accommodated in the pressure control chamber. Preferably, the pressure control device is stored at atmospheric conditions before the beverage and the pressure control device are brought into contact.

1. A container comprising a compartment comprising a carbonated beverage, wherein the container further comprises a pressure control device, the pressure control device comprising a pressure control chamber extending within the compartment, in contact with the beverage, wherein the control chamber has at least one movable wall part for operating a mechanism for opening and/or closing a gas supply opening of a gas holder, wherein the gas holder comprises carbon dioxide gas and the gas supply opening opens into the compartment for pressurizing the beverage, wherein in the pressure control chamber a scavenger is included, wherein the scavenger is a CO2 scavenger and the control chamber is filled with a gas different from the carbon dioxide gas, the scavenger being present in a sufficient amount to effective scavenge CO2 gas which migrates from outside the chamber to inside the chamber. 2. A container according to claim 1, wherein the scavenger is designed for capturing at least CO2 gas entering into the pressure control chamber through a wall thereof from the compartment. 3. A container according to claim 1, wherein the scavenger is selected from the collection of CO2 absorbing and/or adsorbing agents. 4. A container according to claim 1, wherein the pressure control chamber is formed in a piston-cylinder assembly, the piston forming said movable wall part and the scavenger being fixedly connected to a wall of the pressure control chamber. 5. A container according to claim 1, wherein the pressure control device is manufactured at least partly from plastic. 6. A container according to claim 1, wherein the pressure control device is accommodated at least partly in the beverage. 7. A container according to claim 6, wherein the pressure control device comprises a gas holder in which a pressure gas is included at a first pressure, while in the pressure control chamber, a second pressure prevails which is lower than the first pressure, said mechanism for opening and/or closing a gas supply opening of the gas holder being designed for having pressure gas escape in a controlled manner from the gas holder to the container to such an extent that the pressure in the container becomes approximately equal to or higher than the second pressure. 8. A method for preparing a beverage container, comprising the steps: manufacturing a container according to claim 1;manufacturing a beverage container;introducing beverage and the pressure control device into the beverage container;sealing the beverage container; wherein before the beverage and the pressure control device are brought into contact, the pressure control device is stored at atmospheric conditions. 9. A method for manufacturing a pressure control device for a beverage container according to claim 1, wherein a pressure control chamber with at least one movable wall part is manufactured, coupled to a valve assembly operable by said wall part, while in the pressure control chamber a scavenger is provided. 10. A container according to claim 4, wherein the scavenger is fixedly connected to one of the fixed walls of the pressure control chamber. 11. A container according to claim 1, wherein the pressure control device comprises walls, wherein the walls of the pressure control device are made of plastic which allows only limited migration of CO2 gas from the beverage into the pressure control chamber. 12. A container comprising at least partly filled with a carbonated beverage, wherein the container further comprises a pressure control device, the pressure control device comprising a pressure control chamber, in contact with the beverage, wherein the pressure control chamber has at least one movable wall part for operating a mechanism for opening and/or closing a gas supply opening of a gas holder, wherein the gas holder comprises pressurized gas and the gas supply opening opens into the beverage, wherein in the pressure control chamber a CO2 scavenger is provided and the pressure control chamber is filled with air, the scavenger being present in a sufficient amount to effectively gas which migrates from outside the chamber to inside the chamber. 13. A container according to claim 12, wherein the pressure control device comprises walls, wherein the walls of the pressure control device are made of plastic which allows only limited migration of CO2 gas from the beverage into the pressure control chamber. 14. A container comprising carbonated beer and a pressure control device which comprises a pressure control chamber, wherein the pressure control chamber has at least one fixed wall and at least one movable wall part for operating a valve of a gas holder, wherein the gas holder comprises pressurized gas and the valve opens into the beer, wherein in the pressure control chamber, a CO2 scavenger is provided and the pressure control chamber is filled with air, the scavenger being present in a sufficient amount to effectively scavenge CO2 gas which migrates from outside the chamber to inside the chamber. 15. A container according to claim 14, wherein the pressure control device comprises walls, wherein the walls of the pressure control device are made of plastic which allows only limited migration of CO2 gas from the beer into the pressure control chamber.
