PROBLEM TO BE SOLVED: To obtain a coating tool with which ink in an ink well part does not spout even when the pressure in the ink well part becomes higher. SOLUTION: This coating tool 1 consists of a container 2, a tip plug 3 and a pen point (a coating part), a valve and a cap. In addition, the valve is built in the container 2 and the tip plug 3 and consists of an exterior facing member 11, an interior facing member 12, a rear end side elastic body 13, a front end side elastic body 15, a valve body 16 and a spring 17. In the valve, the valve element 16 usually clogs a coating part side opening 36. As a result, no dripping of ink or the like occurs. When the pen point 5 is depressed, the valve element 16 is moved, resulting in clogging a well part side opening 22 and simultaneously releasing the coating part side opening 36. Since the coating part side opening is released at this time, though the ink stored in a valve chamber or the like flows in a coating part side, the well part side opening is clogged with the valve element, the coating part side is shut off from a liquid well part so as not to be influenced by the pressure in the liquid well part. As a result, the spouting of the ink is checked. |
