ABSTRACT:
Disclosed is an applicator in which the air within the inner barrel of a cap is designed to enter into the fluid tank of the applicator to increase the internal pressure of the fluid tank in the process that the cap is engaged with the body of the applicator, so that the fluid tank need not be pressed between the fingers for application of the fluid to be applied. The cap has a valve member provided with a pushing piece disposed in the inner barrel thereof, and the application ball is designed to retract from the caulked front edge of the tip when the application ball is abutted against the pushing piece of the valve member in the process that the cap is engaged with the body of the applicator, whereas the application ball is designed to disengage from the pushing piece of the tip and resume contact with the caulked front edge of the tip when the cap is fully engaged with the body of the applicator.
