<P>PROBLEM TO BE SOLVED: To fit an inner bag into a transportation tank so that the filling failure or the inner bag breakage is prevented from occurring. <P>SOLUTION: A positioning mark and a folding line position indicating mark 46 are formed on an inner bag body 21. With an inner bag supply/discharge port 22 directed downward, the inner bag body 21 is folded inwardly twice at its both side edges in parallel with the longitudinal center line. The folded inner bag body 21 is further folded inwardly several times from its both ends to the inner bag supply/discharge port 22. When the inner bag supply/discharge port 22 is inserted into a tank supply/discharge port 15, the positioning mark is brought in line with the longitudinal center line of a tank body 11. After the inner bag supply/discharge port 22 is attached to the tank supply/discharge port 15, the inner bag body 21 is unfolded in the longitudinal direction of the tank, whereon a folding line 47 of the end 21m of the inner bag body 21 at the inner bag supply/discharge port side is located above the level of folding line position indicating mark 46. As a result, the folding line 47 is positioned to be separate from the inner bag supply/discharge port 22, which prevents the liquid 6 from filling into the end 21m at the inner bag supply/discharge port side in the early stage of liquid filling, thus prevents a filling failure from occurring. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
