PROBLEM TO BE SOLVED: To provide a volatilization device that allows suction wicks to be easily inserted and spillage to be minimized when the device is overturned.SOLUTION: An upper sloping surface 83 which is sloped toward an external peripheral direction, as it goes upward, is formed in the external peripheral part of an opening 81 of a retained element 15 where the suction wick 19 is inserted. This allows the suction wicks 19 to be guided to the opening 81 along the upper sloping surface 83 in the event that the suction wicks 19 interferes with the upper sloping surface 83 of the opening 81, and the opening 81 to be reduced in size to one allowing insertion of a predetermined number of the suction wicks 19. The opening area of the opening 81 can thereby be kept to a minimum without making it more difficult to insert the suction wicks 19 into the opening 81. Consequently, accidental spillage of a liquid chemical 11 when the device is overturned can be minimized while the absorbent wicks 19 can be easily inserted into the device.COPYRIGHT: (C)2012,JPO&INPIT【課題】吸上芯の挿入を容易としつつ転倒時のこぼれを抑制することができる揮散装置を提供する。【解決手段】吸上芯19を挿通する被保持体15の開口部81の外周部に上方へ向かうに従って外周方向に向けて傾斜する上部傾斜面83を形成することで、吸上芯19が開口部81の上部傾斜面83に干渉した場合に吸上芯19を上部傾斜面83に沿って開口部81に案内することができ、所定数の吸上芯19を挿入可能な大きさまで開口部81を小さくすることができる。これにより、開口部81への吸上芯19の挿入容易性を損なうことなく、開口部81の開口面積を最小限に抑えることができる。したがって、吸上芯19の挿入を容易としつつ、転倒時での液状薬剤11の不用意なこぼれを抑制することができる。【選択図】図3
