PROBLEM TO BE SOLVED: To provide a chemical liquid volatilizer allowing facile replenishment of a chemical liquid into a chemical liquid container without detaching a wick member from the chemical liquid container, and furthermore preventing that the chemical liquid flows out to the outside even when the chemical liquid container has fallen.SOLUTION: This chemical liquid volatilizer includes: the chemical liquid container 2 the wick member 3 sucking and volatilizing the chemical liquid a holding member 4 provided in an upper opening 20 of the chemical liquid container 2, and holding the wick member 3 in a state that an upper end part of the wick member 3 is exposed outside the chemical liquid container 2 a cover member 5 provided on the holding member 4 and a cap 6 provided on the cover member 5. The holding member 4 has one or more inlets 46 through which the chemical liquid can be injected into the chemical liquid container 2. The cover member 5 can openably close the inlets 46 of the holding member 4, and has an insertion port 53 through which the upper end part of the wick member 3 is inserted.COPYRIGHT: (C)2013,JPO&INPIT【課題】芯部材を薬液容器から取り外すことなく、薬液容器内に薬液を手軽に補給することができるうえ、薬液容器が倒れた場合でも薬液が外部に流出することを防止できる薬液揮散器を提供する。【解決手段】薬液揮散器は、薬液容器2と、薬液を吸い上げて揮散させる芯部材3と、薬液容器2の上部開口20に設けられ、芯部材3の上端部を薬液容器2の外部に露出させた状態で芯部材3を保持する保持部材4と、保持部材4上に設けられるカバー部材5と、カバー部材5上に設けられるキャップ6とを備える。保持部材4は、薬液容器2の内部に薬液を注入可能な少なくとも1つの注入口46を有している。カバー部材5は、保持部材4の注入口46を開閉自在に塞ぐことが可能であり、かつ、芯部材3の上端部を挿通する挿通口53を有する。【選択図】図1
