Or a dedicated tank truck is used.

[0003] When by the FIBC bag, polyethylene, by a sheet material having flexibility such as polypropylene loading into the truck bed, which is formed in a bag shape suitable for loading and unloading size (about volume 1 to 2 m ³⁾ The granular material is divided and filled into the flexible container bag, and the flexible container bag is loaded on the truck bed and transported to the destination,
After arriving at the destination, the flexible container bag is lowered, the mouth is opened at a predetermined place, and the granular material is discharged.

In the case of the above-mentioned tank truck, the tank is filled with powder and granules and transported to the destination. After arriving at the destination, the discharge port is opened to discharge the powder and granules.

[0005]

However, in the case of the above-mentioned flexible container bag, not only the complicated operation of filling the granular material into the flexible container bag, unloading the flexible container bag, and discharging the granular material is forced, but also a plurality of flexible container bags are required. Foreign matter adhering to the flexible container bag itself to fill the flexible container bag, mixing of fiber waste when the flexible container bag is made of fiber, and increasing the possibility of foreign material contamination due to the small size of the flexible container bag In addition, there is a problem that dust is generated at the time of filling and discharging the granular material into the flexible container bag and the working environment is deteriorated.

Furthermore, it takes a lot of labor to clean the flexible container bag when it is reused, and even if the empty flexible container bag is folded, it does not become very small in volume, and there is a limit to loading another cargo. There was a problem.
