摘要： PURPOSE:To fill a liquid easily and inexpensively by a method wherein a flexible bag is connected to a filling machine, and the flexible bag is manually expanded by air, and the air is replaced by a filling liquid after the expansion of the flexible bag, without a special control unit. CONSTITUTION:A flexible bag is connected to a filling nozzle 01 for which an internal cylinder 1 which becomes an air passage 5, and an external cylinder 4 which becomes a liquid passage 4b on the external periphery of the air passage 5 are integrally formed. The title filling machine is a filling machine which fills a filling liquid by replacing air with the filling liquid, in a flexible bag with a composite valve 02 which respectively communicates with the air passage 5 and the liquid passage 4b. The filling nozzle 01 is movably provided on a sliding cylinder 34 which is fixed on a support frame 18 of the filling machine main body, and in the air passage 5, a second valve 23 which divides the air and liquid in the composite valve 02, and a movable sliding valve 32 which is pressed by a spring 33 are liquid-tightly press-fitted.
