PROBLEM TO BE SOLVED: To reduce burdens on a worker by reducing the quantity of air necessary to be fed till the compression force is actually applied to a bag-shaped container.SOLUTION: The bag-shaped container is pressurized by feeding a fluid into a bag body by using a pump and inflating the bag body with the bag-shaped container filled with a liquid substance held in the space 18 between the bag-shaped bag body 11 and a holding sheet 15, and the liquid substance inside the bag-shaped container is extruded. The bag body has a built-in structure 31 for preventing contact of opposite inner surfaces of the bag body.COPYRIGHT: (C)2010,JPO&INPIT【課題】袋状容器に実際に圧縮力が加えられるまでに必要な空気の送り込み量を低減して、作業者負担を軽減する。【解決手段】袋状のバッグ本体11と保持シート15との間18に液状物が充填された袋状容器を保持させた状態でポンプを用いてバッグ本体内に流体を送り込みバッグ本体を膨らませることによって、袋状容器を加圧し袋状容器内の前記液状物を押し出す。バッグ本体の対向する内面同士が接触するのを防止する構造物31がバッグ本体に内蔵されている。【選択図】図2
