To improve the degree of freedom of selection when using volatile chemicals such as air fresheners or deodorants. The present invention is provided with a soft inner-side bag body (12) formed of a gas-impermeable film (14) and having a volatile chemical (15) sealed therein, and a soft outer-side bag body (13) for accommodating the inner-side bag body (12). The inner-side bag body (12) is configured to be tearable as a result of the interior pressure being increased by an external force, the outer-side bag body (13) has one surface and another surface facing same, at least one of the surfaces being composed of a microporous sheet (17) having a plurality of micropores through which the volatile chemical (15) can infiltrate.本發明之目的在於使用芳香劑或消臭劑等之揮發性藥劑時提高其選擇彈性。本發明包含以非氣體透過性薄膜14形成且於內部封入揮發性藥劑15之軟質之內側袋體12、及收容該內側袋體12之軟質之外側袋體13，且內側袋體12以可由外力造成之內壓上升而拆封之方式構成，外側袋體13具有一面及與其對向之另一面，至少一面以具有可供揮發性藥劑15浸潤之複數個微孔之微多孔質薄片17構成。
