Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a closed container suitably used for transporting granular materials.

[Background technology]

For example, in the case of synthetic resin molding, material is generally supplied to the hopper of a molding machine using air conveyance using pipes. Not only does it complicate the worksite (at least two pipes are required for air and material, and when multiple materials need to be mixed, a corresponding number of pipes are required for each molding machine), but it also reduces the dust surrounding the machine. In addition to the cumbersomeness of the clean amplifier, the influence of noise from the power source for pneumatic transport cannot be ignored, and there are also problems on the work site, such as the need for work space. If this becomes large, there are problems in material molding, such as separation and segregation and a decrease in moisture content.
