摘要：PURPOSE:To prevent the mixing of a shield member into a liquid by connecting a weighing measure to a supply source of the liquid through a check valve while a check valve is provided on a filling conduit extending from the weighting measure for communication of a discharge path with the upper part thereof. CONSTITUTION:A supply source 1 of a liquid to fill a container communicates with a weighing measure 3 through a liquid supply path 2. A check valve 4 is so arranged in the liquid supply path 2 to allow the flow to the weighing measure 3 from the supply source 1 while checking the flow in the opposite direction. A filling conduit 5 is extended to fill the container with the liquid from the weighing measure and is also provided with a check valve 6 inside to allow the flow in the direction of running from the weighting measure 3 while checking the flow in the opposite direction. This eliminates the need of bringing the container into contact with a filling device thereby preventing the mixing of a shield member into the liquid completely regardless of wearing thereof.
