However, both required labor and were poor in workability. Especially for forklift trucks, it was necessary to secure a sufficient operating passage, and the stacking was limited to two stages, which was inconvenient to handle. In addition, both of them have a drawback that an arbitrary container cannot be taken out during storage, a work space is large, and space efficiency is poor. On the other hand, the granular material is filled in the container, stored, and discharged from the container for the next step,
Since these filling and discharging processes are manually performed on a container carried by a forklift or a crane, there is a drawback that powder particles are scattered and workability is deteriorated. Further, conventionally, a powdery or granular material container having an inflow port at an upper portion and an outflow port at a lower side portion is used, and the powdery or granular material is discharged from the outflow port by inclining the container. However, it is difficult to reduce the size of the container because two openings must be formed.
