PROBLEM TO BE SOLVED: To improve a lock mechanism for prevention of malfunction in a medicine spray device.SOLUTION: A lock member 20, which is capable of advancing/retreating at an appropriate position of a storage part body 11, is provided on a medicine spray device 10 comprising: the storage part body 11, which can replaceably store a medicine container equipped with a spray stem for spraying a medicine at an upper end part thereof, therein； and a depressing member 12 which is provided on an upper part of the storage part body 11 and depresses the spray stem of the medicine container, and has a spray port 16 which can spray the medicine to the exterior. The lock member 20 blocks depression of the depressing member 12 and maintains a lock state during non-use of the device, and by pressing the lock member 20, the lock state is released, thereby enabling depression of the depressing member 12. After the depression member 12 is depressed to spray the medicine in the medicine container to the exterior from the spray port 16, the lock member 20 is returned to an original position, and the depression member 12 is returned to an upper position, whereby depression of the depressing member is blocked and the depressing member becomes the lock state during non-use.SELECTED DRAWING: Figure 1【課題】薬剤噴霧装置における誤作動防止のためのロック機構を改良する。【解決手段】上端部に薬剤噴霧用の噴霧用ステムを備える薬剤容器を交換可能に内部に収納できる収納部本体11と、この収納部本体11の上部に設けられ、薬剤容器の噴霧用ステムを押下し、薬剤を外部に噴霧することのできる噴口部16を有する押下部材12とからなる薬剤噴霧装置10に、収納部本体11の適宜位置に出没自在のロック部材20を設ける。このロック部材20は、装置の不使用時に前記押下部材12の押下を阻止してロック状態を維持し、このロック部材20を押し込むことによって前記ロック状態が解除されて前記押下部材12の押下が可能となる。押下部材12を押下して薬剤容器内の薬剤を噴口部16から外部に噴霧した後、ロック部材20が元の位置に復帰し、押下部材12が元の上方位置に復帰して押下部材の押下が阻止されて不使用時のロック状態となる。【選択図】図１
