PROBLEM TO BE SOLVED: To easily fill a highly foamable liquid without expensive equipment. SOLUTION: The container main body 1 of a large-sized flexible container A, which has in the container main body 1 a discharging opening 2 for filling and stores and conveys a liquid B filled in the container main body 1, is provided with a deaerating opening 3 provided with a cock 4. The injection opening 2 of the container A and the filling nozzle 6 of a filling device are air-tightly connected together, also, air in the container is drawringly removed from the deaerating opening 3 with the cock 4 open, and then, after the cock 4 is closed, the liquid B is filled into the container main body 1 by the filling device. Therefore, by providing the large size flexible container with the deaerating opening having a gas circulation control means such as the cock, which is separate from the injection opening, even a highly foamable liquid can easily be filled into the large size flexible container by an ordinary general-purpose filling equipment, without the use of conventional expansive filling equipment, for example with the use of a vacuum pump, or even without such a pum the fluid can be filled. |
