PURPOSE:To prevent excessive discharging of a coating liquid at the time of application and prevent suffocation in spite of erroneous drinking by connecting and holding an inside cylinder and a cylindrical part for pressurizing the inside of a coating liquid tank and forming a vent hollow groove in a cap body and a vent hole in this groove. CONSTITUTION:The inside cylinder 2 to hermetically seal a tip and the cylindrical part 3 for pressurizing the inside of the coating liquid tank are connected and held to the inner peripheral surface of the cap body 1 by a rib 4. The vent hollow groove 11 arriving at a tail end is formed at the peripheral surface of the cap body 1 and the vent hole 5 is formed in this vent hollow groove 11. The inside of the coating liquid tank is not excessively pressurized by mounting of the cap and the pressure before cap mounting is maintained if the cap is formed in the manner described above. The excess discharge of the coating liquid at the time of applying the liquid next time does not arise either. The vent path consisting of the vent hollow groove 11, the vent hole 5 and the spacing between the rib 4 and the rib 4 is assured in spite of erroneous drinking. |
