A containing apparatus for volatile liquid includes a container, a breathable membrane, a rupturable substrate, a rear casing and a pressing piece. The container receives a volatile liquid. An accommodating portion of the container has an opening. The rupturable substrate covers the opening of the accommodating portion for remaining the volatile liquid therein without leakage in an unused status. The breathable membrane is positioned at an outer side of the rupturable substrate. The rear casing is positioned at an outer side of the breathable membrane and has a through hole. The pressing piece is configured to be pressed toward the breathable membrane and the rupturable substrate. The breathable membrane is arranged between the pressing piece and the rupturable substrate. A part of the pressing piece can pass through the through hole of the rear casing and breaks the rupturable substrate to form a breaking hole, yet the breathable membrane with resilience is not broken. Therefore, the volatile liquid can be flowed out through the breaking hole of the rupturable substrate and is absorbed by the breathable membrane for vaporing to the atmosphere.一種揮發性液體的容納裝置包括一容置殼體、一可破裂層、一微孔膜、一背殼及一按壓件。容置殼體用以容納揮發性液體,容置殼體的容置部形成一容置開口。可破裂層覆蓋於容置部的容置開口,在未使用狀態下,以保留揮發性液體於容置部內而不洩漏。微孔膜置於可破裂層的外側;背殼置於微孔膜的外側並且形成一通孔。微孔膜位於按壓件與可破裂層之間,按壓件的部分穿過背殼的通孔而壓破所述可破裂層而形成一破口,微孔膜具有彈性而不被按壓件穿破,從而揮發性液體經過可破裂層的破口以及被所述微孔膜吸收而揮發至外界。
