PROBLEM TO BE SOLVED: To provide a volatilizing container which can be reliably mounted the cover or the like of a blow port of a ventilation apparatus without being followed by the complication of a structure.SOLUTION: A volatilizing container comprises: a container body 1 including a peripheral wall 1a and a bottom wall connected integrally to the lower end of the former wall for containing a volatile content directly or through an intermediate dish in a partition recess M formed on the inner side and for volatilizing the content through an upper open end and a cover 2 enclosing the container body in a manner unable to leave while leaving the upper open end and in a rotatable manner. The bottom wall of the container body is equipped on its lower face with a connecting portion 3 connected detachably to a stationary portion through a leading open portion 3a thereby to hold the container body at the stationary portion. The cover is equipped with a retaining portion 4 for bringing a protruding end face 4a thereof into abutment against the stationary portion by the rotation of the cover around the container body, thereby to prevent the connecting portion from leaving the stationary portion, and a locking mechanism 5 is so interposed between the container body and the cover as to block the rotation of the cover thereby to keep the abutting position against the stationary portion.COPYRIGHT: (C)2014,JPO&INPIT【課題】構造の複雑化を伴うことなしに換気機器の吹き出し口のカバー等に確実に取り付けることができる揮散用容器。【解決手段】周壁1aとその下端に一体連結する底壁からなり、内側に形成された区画凹所Mに揮発性の内容物を直接または中皿を介して間接的に収納するとともに、上部開放端を通して内容物を揮散させる容器本体1と、容器本体を上部開放端を残して抜け出し不能かつ回動可能に取り囲むカバー2とを備え、容器本体の底壁の下面に、先端開放部3aを通して固定部位に着脱可能に連係して容器本体を固定部位に保持する連係部3を設け、カバーに、容器本体の周りに沿うカバーの回動にてその突端面4aを固定部位に当接させて連係部の、固定部位からの離脱を防止する係止部4を設け、容器本体とカバーとの相互間に、カバーの回動を阻止して係止部の、固定部位に対する当接姿勢を維持するロック機構5を設ける。【選択図】図1
