< Topic >Preventing the generation of the bridge phenomenon in all inside the storage tank securely, until the inside of the storage tank becomes the nul, with powdered, it offers the spreading device of the medicine which can maintain the fluidization of the medicine whose flowability is bad continuously.SolutionsBeing installed in the vibrating motor 6 which can install the spreading section 2 which, is installed on cartridge head of the storage tank 1 of hopper condition, in spreading opening 4 of particular cartridge head and this vibrating motor 6 as it closes spreading opening 4, it constitutes with from the spreading opening component 7 which possesses the multiple spreading holes 4a. Furthermore, receiving directly from vibrating motor, 6 itself and vibrating motor 6 the vibration being spread in the medicine inside storage tank 1 by the spreading opening component 7 which vibrates, with powdered inside storage tank 1, it prevents the generation of bridge phenomenon of the medicine whose flowability is bad.< Choice figure >Drawing 3【課題】収容タンク内全域におけるブリッジ現象の発生を確実に防いで、収容タンク内が空になるまで粉末状で、流動性の悪い薬剤の流動化を継続的に維持できる薬剤の散布装置を提供する。【解決手段】ホッパ状の収容タンク1の底部に取り付けられる散布部2を、当該底部の散布口4に取り付けられる振動モータ6と、この振動モータ6に取り付けられて散布口4を閉鎖するとともに、複数の散布孔4aを有する散布口部材7とから構成する。さらに、振動モータ6自体および振動モータ6から直接受けて振動する散布口部材7によって収容タンク1内の薬剤に振動が伝播されて収容タンク1内での粉末状で、流動性の悪い薬剤のブリッチ現象の発生を防ぐ。【選択図】図3
