Description

TECHNICAL FIELD The present invention relates to a chemical liquid volatilization device for diffusing volatile substances into a room or a car.

BACKGROUND ART Conventionally, as a chemical solution volatilization device installed indoors or in a car, for example, one described in Patent Document 1 has been proposed. The device described in Patent Document 1 includes a cylindrical exterior body, an interior body held within the exterior body, and an absorbent body impregnated with a volatile substance such as an aromatic agent, which is fixed to the interior body. . Both openings of the exterior body are closed by respective closing plates, and each closing plate is provided with a pull-top type lid that can be separated leaving an outer edge.

When using the chemical volatilization tool, first, pull the pull tab on one of the closing plates of the exterior body and pull it to separate the lid from the closing plate to form a volatilization port. Place the chemical solution volatilization tool in a predetermined location with the volatilization port facing upward. When the volatilization of the aromatic agent decreases after being used in this state for a certain period of time, the exterior body is turned upside down and the lid provided on the other closing plate of the exterior body is cut off to form a volatilization port. By turning the exterior body upside down, the aromatic agent impregnated below the absorbent body evaporates from the newly formed volatilization port, leaving no aromatic residue behind.
