PROBLEM TO BE SOLVED: To provide a volatilizing agent container which can simplify operation for opening a container body and bringing a volatilizing agent into a volatilization state, and allows easy confirmation of an opened state of the container body from its appearance.SOLUTION: A volatilizing agent container 1 includes a container body 20 which accommodates a volatilizing agent R therein, and a cover 30 which covers the container body 20 in an inverted state from below. A side wall 31 of the cover 30 has a side wall lid part 34 which is connected to the side wall 31 through a hinge 33. Outward swinging displacement of the side wall lid part 34 is blocked by a cover film 10 covering the whole circumference of at least a part of the side wall lid part 34. The inner surface of the side wall lid part 34 is provided with a support part which supports the container body 20 from below by bringing an inclined part 35a, inclined downward toward the inside of the cover 30, into contact with a shoulder part 23 of the container body 20, and, by pushing in the container body 20 after removal of the cover film 10, makes a body part 22 of the container body 20 along the inclined part 35a to swing and displace the side wall lid part 34 to the outside.COPYRIGHT: (C)2015,JPO&INPIT【課題】容器本体を開封し、揮散剤を揮散させる状態とするための操作を簡易化させるとともに、開封状態にあることを外観から容易に確認することができる揮散剤容器を提供する。【解決手段】内部に揮散剤Rを収容する容器本体20と、倒立状態とした容器本体20に下方から被さるカバー30と、を備えた揮散剤容器1であって、カバー30の側壁31は、ヒンジ33を介して連結する側壁蓋部34を有し、側壁蓋部34は、該側壁蓋部34の少なくとも一部を全周にわたって覆うカバーフィルム10によって、外側への揺動変位が阻止され、該側壁蓋部34の内面に、カバー30の内側に向かって下方に傾斜する傾斜部35aを容器本体20の肩部23に当接させて、該容器本体20を下方から支持する一方、カバーフィルムを除去して該容器本体20を押し込むことで、該容器本体20の胴部22を該傾斜部35aに沿わせて該側壁蓋部34を外側へ揺動変位させる支持部を設けた、ことを特徴とする。【選択図】図1
