A coating tool (12) comprises a coating tool body (2) having a liquid storage portion (2a) for storing a coating liquid, and a cap (10) detachably fitted and mounted on the coating tool body to be in tight contact with it. In the course of mounting the cap (10), the volume of a sealed space (A) formed in the cap (10) is decreased to supply air to the main barrel (2a), thereby pressurizing the interior of the main barrel (2a). At least one of an inner surface (10b1) of the cap (10) and an outer surface of a mouthpiece (2b) which are brought into tight contact with each other in the mounting operation of the cap (10) is coated with a sealing agent (16). In the coating tool for applying a correction liquid or the like, the ability to pressurize the interior of the liquid storage portion (2a) can be improved without complicating the structure in the cap (10), and the cap can be attached and detached smoothly.
A coating tool comprising a coating tool body having a liquid storage portion for storing a coating liquid, and a cap detachably fitted and mounted on said coating tool body to be in tight contact with said coating tool body, characterized in that said liquid storage portion is supplied with air by decreasing a volume of a sealed space formed in said cap in the course of mounting said cap, thereby to be pressurized, and
