Abstract: An applicator in which the air within an inner barrel of a cap to the applicator is enabled to flow readily into the fluid tank of the applicator to increase the internal pressure of the fluid tank when the cap is engaged with the neck of the applicator, so that the fluid tank of the applicator need not be pressed between the fingers of a user for application of a highly viscous fluid. The inner barrel of the cap includes a curved, elastically deformable valve-opening member made of a highly flexible material bearing against the closed end of the cap. When the cap is engaged with the body of the applicator, the valve-opening member abuts against an application member to retract the application member from a caulked front edge of the tip of the applicator so as to form a clearance between the application member and the caulked front edge of the tip through which air can readily flow to increase the internal pressure of the fluid tank.
