ABSTRACT:
The application relates to a flexible container (3) made of film material for containing drinks, comprising a fin opening as well as film storage means which delimit a first compartment and a second compartment (17, 18, 19) of the container and which release a second compartment (18, 19) when a predetermined degree of filling of the first compartment (17) is reached. By means of the film storage means, which, for example, can be formed by folding the side strips (20, 21) double in the longitudinal direction and holding them in place with the aid of adhesive tape, adhesive or fusion welding of the film material, uniform filling of the first compartment can be obtained, the flexible container largely remaining out of contact with the walls of the surrounding outer container. When the first compartment (17) has been filled the film storage means are released by the increase in the fill pressure and the second compartment (18, 19) can be filled so that uniform contact of the flexible container with the wall of the outer, rigid container is obtained. Using the flexible container and using the filling method according to the present invention high fill rates can be achieved and stresses are prevented from becoming too high in certain sections of the flexible container.
