PROBLEM TO BE SOLVED: To provide a volatilization device which can prevent leakage of a chemical to the exterior, even if the device is fallen.SOLUTION: A volatilization device 10 comprises: a contour body 5 which has at least a container 20, and defines a contour of the volatilization device 10 a cylindrically formed inside plug 40 comprising a large diameter part 41 which is located inside an opening of the container 20, and a small diameter part 42 which is so formed as to be continuously and coaxially with the large diameter part 41, has an outer peripheral surface 42a having a diameter smaller than an outer peripheral surface 41a of the large diameter part 41 and is located in the container 20 and a liquid suction member 60 which is located in the inside plug 40. A bottom wall part 45 of the large diameter part 41, is provided with a hole 47 which penetrates the bottom wall part 45 in an axial direction and is formed on a radial direction outer side with respect to the small diameter part 42, and an enclosure wall 50 which is so formed on a bottom surface 45a of the bottom wall part 45 and an outer peripheral surface 42a of the small diameter part 42 as to surround the hole 47 and be opened in a radial direction.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】転倒しても薬液が外部へ漏れ出ることを防止できる揮散装置を提供すること。【解決手段】揮散装置10は、容器20を少なくとも有し、揮散装置10の外郭を規定する外郭体5と、容器20の開口の内側に配置される大径部41、及び大径部41に連続して大径部と同軸に形成され、41大径部の外周面41aよりも小径な外周面42aを有し容器20内に配置される小径部42を備え、筒状に形成された中栓40と、中栓40内に配置される吸液部材60と、を備える。大径部41の底壁部45は、小径部42よりも径方向外側に、軸方向に底壁部45を貫通する孔47が形成され、底壁部45の底面45a及び小径部42の外周面42aに、孔47を囲い、径方向に開口する囲い壁部50が形成される。【選択図】 図2
