Provided are a gas treatment device and a gas treatment method that make it possible to keep low the amount of VOC that sticks to a filter for adsorbing ozone, and to keep the VOC that is discharged at a low concentration over the long term. The gas treatment device takes in a gas to be treated containing VOC and oxygen from an air intake port, treats same and thereafter discharges same from an air discharge port that is provided to a different location from that of the air intake por. The gas treatment device comprises: a gas flow path configured so as to enable communication between the air intake port and the air discharge port; a blower device for causing the gas to be treated to flow from the air intake port side toward the air discharge port side; an ultraviolet light source that is arranged inside the gas flow path and emits ultraviolet rays of a wavelength of 230 nm or less; a filter that is arranged inside the gas flow path closer to the air discharge port side than the ultraviolet light source and adsorbs at least ozone; and a control unit for controlling operation of the blower device. The control unit causes the blower device to start a blowing operation after the emission of ultraviolet rays from the ultraviolet light source has started.

A containing apparatus for volatile liquid includes a container for receiving a volatile liquid, a breathable membrane, a rupturable substrate, an upper casing, and a pressing member. An accommodating portion of the container has a receiving opening. The rupturable substrate covers the receiving opening for retaining the volatile liquid therein without leakage in a non-use state. The breathable membrane is disposed above the rupturable substrate. The upper casing is disposed above the breathable membrane and has a through-hole. The pressing member is movably connected to the upper casing and can be pressed toward the breathable membrane and the rupturable substrate. The breathable membrane is arranged between the pressing member and the rupturable substrate. A part of the pressing member can pass through the through-hole and break the rupturable substrate to form a breaking hole, yet the breathable membrane is not broken.
