PROBLEM TO BE SOLVED: To provide a powder dispensing container in which a dispensing preparation operation is simple and proper quantitative powder can always be dispensed stably.SOLUTION: A powder dispensing container is formed by combining an air pressure feed mechanism 40 for pumping air, a fixed plug 30 engaged with the air pressure feed mechanism 40, and cartridge 2 with a syringe part 12 for receiving powder P. The cartridge 2 includes a recess 12a recessed in a predetermined height range of an inner circumferential surface of the syringe part 12, and an inside plug 20 installed in the inside of the syringe part 12. The powder dispensing container is characterized in that the inside plug 20 is pushed up by a projection 35 of the fixed plug 30 when the cartridge 2 is combined with the fixed plug 30, and an air flow path is formed for ejecting the powder P received in the inside of the syringe part 12 to the outside using the air pumped by the air pressure feed mechanism 40.SELECTED DRAWING: Figure 2【課題】投与準備操作が簡便であり、常に適切な量の粉末を安定して投与することができる粉体投与容器を提供することである。【解決手段】空気を圧送する空気圧送機構４０と、該空気圧送機構４０に係合する固定栓３０と、粉体Ｐを収納するシリンジ部１２を備えたカートリッジ２を組み合わせてなる粉体投与容器において、該カートリッジ２は、該シリンジ部１２の内周面の所定の高さ範囲にて凹んだ凹部１２ａと、該シリンジ部１２の内部に設置される中栓２０とを備え、該カートリッジ２と固定栓３０を組み合わせたときに、該中栓２０が固定栓３０の突出部３５にて押し上がり、該空気圧送機構４０による圧送された空気によりシリンジ部１２内部に収容されていた粉体Ｐを外部に噴出させる空気流路が形成されることを特徴とする粉体投与容器。【選択図】図２
