PROBLEM TO BE SOLVED: To temporarily increase a volatilization amount as necessary.SOLUTION: A volatilization container 1 includes: a container body 2 in which a volatile liquid W is stored and an introduction hole 25 for introducing air thereinto and a volatilization window 30 for vaporizing a vaporization gas occurring from the volatile liquid are formed a pipe 3 which is disposed in the container body with a lower end opening part positioned at the bottom part 11 side of the container body and an upper end opening part positioned at the introduction hole side and to which air is sent a valve body 41 which is provided between the introduction hole and the upper end opening part of the pipe, allows inflow of the air to the pipe through the introduction hole, and restricts outflow of the air from the pipe through the introduction hole and an air pump 4 in which a suction hole 53 is formed, the air pump 4 which is formed so as to elastically deform and attached to the container body so that its interior part communicates with the introduction hole.COPYRIGHT: (C)2016,JPO&INPIT【課題】必要に応じて揮散量を一時的に増加させること。【解決手段】揮発性液体Wが収容されると共に、内部に空気を導入する導入孔25及び揮発性液体から生じる気化ガスを揮散させる揮散窓30が形成された容器体2と、容器体の底部11側に下端開口部が位置し、且つ導入孔側に上端開口部が位置した状態で容器体の内部に配設され、空気が送り込まれるパイプ3と、導入孔とパイプの上端開口部との間に設けられ、導入孔を通じたパイプへの空気の流入を許容し、且つ導入孔を通じたパイプからの空気の流出を規制する弁体41と、吸気孔53が形成されると共に弾性変形可能に形成され、導入孔に対して内部が連通するように容器体に装着された空気ポンプ4と、を備えている揮散容器1を提供する。【選択図】図2
