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 pred
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.

The invention claimed is: 1. Filling method for filling a flexible container with a fluid substance, comprising the following steps: placing the flexible container in a relatively rigid container, the flexible container being provided with a film material for containing a fluid substance comprising a fill opening and a partitioning means along the which a first container wall part is placed against a second container wall part, the partitioning means dividing the container in a first and second compartment, characterised in that the partitioning means comprises a restraining member which maintains a substantially fluid tight separation of the first and second compartment until a predetermined pressure is achieved in the first compartment, wherein at the predetermined pressure, the restraining member is released by the fill pressure for placing the first and second compartment in fluid communication; filling the first compartment with the fluid substance via a fill opening in the container, activating the film storage means via the fill pressure such that the second compartment is released, and filling the second compartment until the film material of the flexible container is at least largely in contact with the wall of the rigid container; wherein, during filling, at least one of a flow rate and a fill pressure is measured and a change in the at least one of the flow rate and the fill pressure is determined on activation of the film storage means. 2. Method according to claim 1, characterised in that air is removed from the flexible container before the flexible container is inserted in the rigid container. 3. Method according to claim 1, characterised in that the flexible container is folded double along closure lines, the container sections folded double being attached to one another by the restraining member which can be released by fill pressure. 4. The method according to claim 1, further comprising inserting said flexible container into a generally cylindrical, rigid outer container; wherein a central cylindrical area is defined between the closure lines; wherein upon filling and expanding the flexible container, vertical sides of the flexible container outside the closure lines do not press against the walls of the rigid outer container; and wherein after release of the closure lines, the flexible container material outside the closure lines is pressed into contact with the rigid outer container.
