Abstract
An applicator includes a valve mechanism that communicates an application liquid tank and an applying part. The valve mechanism has at least a valve stem and a valve holder for holding the valve stem therein, the application liquid can flow through a gap between the valve stem and the valve holder, the valve stem is formed with an air exchange hole, and, the air exchange hole can be opened and closed by an opening/closing member that opens/closes when the pressure on the application liquid tank side becomes negative or positive compared to that on the applying part side. The applicator is capable of exchanging air after discharging the application liquid even if the applicator is equipped with a valve mechanism that opens its valve by increasing the internal pressure of the ink tank.
