Definitions

• the invention relates to a system for the transport and storage of carbonated beverages, in particular beer, in which the beverage is transported to the place of consumption by a vehicle in which there is at least one stationary pressure tank at the point of use, which has two openings ⁇ hen, one of which is closed with a pressurized gas fitting and the other with a drinks fitting, in which the pressurized gas fitting with a pressurized gas source and the drinks fitting for the purpose of feeding the beverage into the pressure tank with the tanker or can be connected to a tap for the purpose of removing the beverage and in which a foil bag connected to the beverage fitting is further arranged in the pressure tank and serves to hold the beverage in the pressure tank.
• the invention has for its object to avoid the reduction in the quality and shelf life of the beverage, especially if this is beer, in the system of the type described above.

• the processing can take place in the processing device mentioned on the tank vehicle or in a separate processing system located at the beverage manufacturer. This processing system is supplied with the mixture from the compressed gas storage unit on the vehicle. The compressed gas storage can then be loaded again with cleaned, oxygen-free compressed gas.
• the independent inventive importance is attached, and which has the purpose of guaranteeing a recovery of the oxygen-free compressed gas in pure form, may consist in the fact that in the pressure tank, a closed pressure gas space connected to the pressure gas fitting is provided is, which is limited by a separating film against the space which is taken up by the fol sack with the drink, which is so large that the closed pressure gas space can vary between the entire interior of the pressure tank and zero. 5 ⁇
• the separating film can be attached to the inner wall of the pressure tank.
• the pressure tank consists of two half-shells which are connected to one another at the point of use.
• the separating film can then be attached to the edge of one of the two half-shells. After the compressed gas has been sucked out of the compressed gas space to a volume of zero, the compressed gas fitting must be closed in order to prevent air from entering the compressed gas space.
• the separating film can be designed as a separate pressurized gas film bag, the open end of which is connected to the pressurized gas fitting.
• the compressed gas film bag before each new filling as well as the beverage film bag.
• a third variant consists in that the film sack has a further open end which is connected to the compressed gas armature, and that the separating film is arranged inside the film sack and with its wall for the purpose of a double-chamber Foil bag is connected.
