A pressure tank is to be filled with a carbonated beverage, in particular beer, without the beverage coming into contact with the walls of the pressure tank. To this end, there is inserted in the pressure tank a plastic bag into which the beverage is introduced. The plastic bag is replaced whenever the tank is to be refilled. The pressure tank is provided with two openings at opposite points which are closed by fittings. The plastic bag is introduced through one of the two openings. To prevent that as the beverage is introduced there remain folds at points of the plastic bag which are already covered by the beverage, it is proposed to introduce the plastic bag into the pressure tank along with a hoselike jacket which as the bag is being filled assures a gradual unfolding thereof.

A method of filling a plastic bag in a pressure tank with a carbonated beverage, in particular beer, the pressure tank being provided with two opposed openings, one of which is closed by a beverage fitting for filling and tapping, and the other by a compressed-gas fitting for the introduction of compressed gas between the tank wall and the plastic bag, in which method the plastic bag is introduced into the pressure tank in the folded condition through an opening therein before the fittings are mounted, a pressure-resistant flow-through connection then being established between the open end of the plastic bag and the filler fitting as the latter is mounted, and in which method compressed gas is then fed to the compressed-gas fitting, and thereupon beverage is fed to the beverage fitting, characterized by the fact that the plastic bag (12) is introduced into the pressure tank (1) inside a hoselike jacket (13), said plastic bag (12) being pulled out of said jacket (13) and said jacket remaining in the pressure tank (1) while the plastic bag (12) is being filled.
