[Prior art] Conventionally, in the pharmaceutical industry and the like, a plurality of types of powdered granules have been stored in large quantities in fixed source tanks, and materials in an amount corresponding to a desired compounding ratio are stored in a portable closed container with a lid. Once, the container is transported to a tumbler (rotary mixing tank) or the like, and then uniformly mixed. The mixed material is transferred to the container again, and the dispensing / transporting device is set in a predetermined position. A compounding / mixing transport system is generally employed in which the mixture is fed into a hopper and supplied to a desired tableting machine or packaging machine.

However, in such a conventional compounding and transporting system, materials contained in a closed container with a lid are used.
When the material mixed and transferred to a tumbler or the like is transferred to a container again, there is a problem that the stored material unnecessarily comes into contact with air or scatters.
