Abstract
An applicator which allows easy control of fluid discharge and also smooth application of the fluid contained therein with no excessive discharge includes a fluid tank, filled with a fluid to be applied, and connected to a stem retaining a ball therein, the ball being rotatably retained in a ball housing formed in the stem in such a way that the ball may partly appear from the tip of the stem and is pushed outward by the outer end face of a movable piece, protruding slightly into the ball housing, resiliently urged by a spring, so as to allow the ball to be normally in contact with the inner caulked edge of the stem, while the ball is also designed to roll in contact with the seat of the ball housing when the fluid is being applied.
