<P>PROBLEM TO BE SOLVED: To provide a liquid applicator which can supply an applied liquid to an application body by the writing pressure in writing, and can easily change performance and quality according to the specification of an applicator. <P>SOLUTION: In the liquid applicator, a valve mechanism part is constituted of a valve body provided at the rear of an axial tip, a valve rod, a coil spring and a valve seat which is constricted and fixed between the rear end of a tip part fitted in from the front end of the axial tip and a step part provided at the front end of the valve body. The opening amount of the valve mechanism part is determined by the space between the front end of the valve rod and the rear end of the valve seat, an application body is inserted into the inner hole of the tip part with its rear end part being fitted to the holding part inner hole of the front end of the valve rod. When the application body is moved to the rear side against the pushing force of the coil spring, the valve mechanism part opens, enabling the application liquid to be supplied to the application body side from the tip end side of a main body container. At the same time, the step part formed on the application body retreated by a specified dimension, abuts on the inner step part of the rear end of the tip part, enabling the application body to be prevented from retreating. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
