【発明の効果】以上説明したように,本発明の粉体の保
存運搬具は装填・分取・払出し操作時に大気との接触を
遮断することができ,大気と遮断した保存状態も圧力計
によって管理することができ,しかも,操作が簡単で移
動運搬も自由に行えるので,高性能粉体の性能劣化を簡
易な手段で防止できるという効果を奏する。As described above, the powder storage / transportation tool of the present invention can cut off the contact with the atmosphere during the loading, sorting, and discharging operations, and the stored state cut off from the atmosphere can also be measured by the pressure gauge. Since it can be managed, and can be easily operated and can be freely moved and transported, there is an effect that the performance deterioration of the high-performance powder can be prevented by simple means.
