<P>PROBLEM TO BE SOLVED: To provide a fluid applicator capable of preventing leakage of a fluid coating liquid such as ink or the like not in use, as well as securing an appropriate amount of the coating liquid and a stable flowing amount of the coating liquid with one knocking operation in use. <P>SOLUTION: The fluid applicator has a refill to be loaded into a barrel body 1 and equipped with a coating liquid storage tube 10 at the pen tip and the back of a ballpoint pen, with the pen tip being retractable interlocked with the knocking mechanism provided on the rear end side of the barrel body 1 and the rear part of the coating liquid storage tube 10 opened, and the pressurizing mechanism 40 for increasing the pressure in the coating liquid storage tube between the rear part of the coating liquid storage tube 12 and the knocking mechanism. The pressurizing mechanism 40 is a fluid applicator which is pressurized and released by the knocking mechanism, and is constituted so that the flow amount of the fluid coating liquid for ten seconds from the ballpoint pen type pen tip is set to 10 to 60 mg, when the inner pressure of the coating liquid storage tube is higher than the outer pressure by 50 to 300 mmHg by the pressurizing mechanism 40. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
