PROBLEM TO BE SOLVED: To provide a medicine-volatilizing container of which time point for the completion of volatilization of a volatilizing medicine is clearly judged and an indicator by which the progress of time is clearly judged.SOLUTION: This medicine-volatilizing container is provided by housing a gas 8 and the volatilizing medicine 7 in a hollow part 4 of a swelling up part 3 of a container main body 2, and closing an opening part of the swelling up part 3 of the container main body 2 with a lid member 6 in this state. When the volatilizing medicine 7 starts to volatilize by penetrating through the lid member 6, the inner pressure of the hollow part 4 changes by following the progress of the volatilization, the lid member 6 is elongated by following the inner pressure change and approaches to the inner surface direction of the swelling up part 3 of the container main body 2 and the contact area of the air in the hollow part 4 against the inner surface of the swelling up part 4 changes (increases) by following the displacement of the lid member 6. When the volatilization is completed, only the gas 8 can be seen by the eye from the surface side of the container main body 2.COPYRIGHT: (C)2003,JPO【課題】 揮散性薬剤の揮散終了の時点を明確に判断できる薬剤揮散容器及び時間の経過を明確に判断することができるインジケーターを提供する。【解決手段】 容器本体2の膨出部3の空所4内に気体8と揮散性薬剤7とを収容し、この状態で容器本体2の膨出部3の開口部を蓋部材6によって閉塞する。揮散性薬剤7が蓋部材6を透過して揮散を開始すると、揮散の進行に追従して空所4の内圧が変化し、空所4の内圧の変化に追従して蓋部材6が延伸して容器本体2の膨出部3の内面方向に接近し、蓋部材6の変位に追従して空所4内の空気の膨出部3の内面に対する接触面積が変化(増加)する。揮散が終了したときには、容器本体2の表面側から気体8のみが目視されることになる。
