  • Patent number: 6185911
    Abstract: The invention concerns a method for filling a two chamber tube made from plastic having a substantially circular cross section and a separation wall made from plastic and extending between two substantially diametrically opposed connecting points of the separation wall and having a length in excess of the diameter of the tube to form, together with the wall of the tube, the two chambers. A filling nozzle is inserted into each chamber for introducing the filling product into the tube and the tube is sealed after removal of the filling nozzles. In order to guarantee reliable filling of the two chamber tube, the separation wall is attached, prior to introduction of the filling nozzles, to the inside tube wall at its end regions bordering the connecting points in such a fashion that the length of the middle region remaining between the two end regions corresponds substantially to the diameter of the tube.
