PROBLEM TO BE SOLVED: To provide a volatile agent container capable of maintaining a volatilization state of a volatile agent.SOLUTION: A volatile agent container comprises: a container body 1 having a neck part 1c on an apex, and forming a storage space of a volatilize agent V therein a cap 2 having a cylindrical part 2c for forming a passage communicating inside and outside of the container body, and fixed and held to the neck part of the container body and a cover body 3 with window, having an impregnation body 4 disposed on an outlet side of the cylindrical part and being attached to the container body. The container body is held in an inverted posture and a top plate 3c of the cover body serves as a mount surface, and the volatile agent is drained via the passage of the cylindrical part and impregnated to the impregnation body, thereby the volatile agent is volatilized via the window 3c of the cover body. The cap comprises a cylinder body 5 whose one end is held to and opened at inside of the cylindrical part, and whose the other end is extended toward a bottom wall part 1a of the container body and opened. Between the cylinder body and cylindrical part, a communication path 6 having an opening area smaller than that of the cylinder body and communicating inside of the container body and an opening end of the cylinder body, is provided.COPYRIGHT: (C)2016,JPO&INPIT【課題】揮散剤の揮散状態を維持する揮散剤容器を提供する。【解決手段】頂部に口頚部1cを有しその内側に揮散剤Vの収納空間を形成する容器本体1と、容器本体の内外につながる通路を形成する筒部2cを有し容器本体の口頚部に固定、保持されるキャップ2と、筒部の出側端に配置される含侵体4を有し容器本体に装着される窓付きのカバー体3とを備え、容器本体を倒立姿勢に保持してカバー体の天板3cを載置面にして揮散剤を筒部の通路を通して流出させるとともに含侵体に含侵させて、含侵体からカバー体の窓3aを介して揮散させる揮散剤容器であって、キャップは、一端が筒部の内側において保持されるとともに開口され、他端が容器本体の底壁部1aに向けて伸延して開口する筒体5を備え、筒体および筒部の相互間に、筒体の開口面積よりも小さい開口面積を有し、容器本体内と筒体の開口端とを連通させる連通経路6を設けたものである。【選択図】図1
