ABSTRACT Packing containers for liquid are often made from a tube of flexible packing material, which is filled with the liquid and thereafter transversely sealed and cut into separate, completely filled packing containers. This method has however hitherto been impossible to use for production of packages for aerated beverages and the like, as such beverages tend to froth when they are filled into the tube. According to this invention the abovementioned disadvantage is avoided in that the liquid to be filled is kept under pressure during its transportation to the bottom end of the tube, where a closed and with liquid completely filled space is limited by the tube itself and by an element which supplies the liquid.
