Description of the Related Art In a ballpoint pen or applicator using a ball as a writing medium, ink contained in an ink container moves toward a chip by gravity and capillary force, and ink is applied to the surface of the ball held by the chip. The ink is supplied and adhered, and the ink is transferred and absorbed onto the paper surface as the ball rotates, whereby writing or application is performed.

分も紙面に接触せしめられる。[0003] This writing or coating is performed by gripping the ball barrel of the ball-point pen or the applicator in a state where it is slightly inclined with respect to the paper surface and pressing the ball at the tip of the chip into contact with the paper surface. Along with the rotating ball, the foremost fore edge portion of the entire circumferential caulking portion formed to hold the ball at the tip of the chip, and the caulked portion continuous to the fore edge portion are brought into contact with the paper surface.

りチップの内縁に巻き込まれてしまうものであった。Conventionally, when a tip of a ball-point pen or an applicator is formed with the entire circumference caulked portion, an edge S is formed at a foremost fore edge portion and a caulked portion continuous with the fore edge fore edge portion. Is common (see FIG. 7).
As shown in FIG. 8, which is an enlarged view of a main part of FIG. 7, if the conventional chip is brought into contact with the paper surface in the state of writing or coating, the edge S comes into contact with the paper surface, causing scratching. As a result, the paper surface was shaved by scratching, and the shaved paper fibers and paper shavings were drawn into the inner edge of the chip from the foremost fore edge portion as the ball rotated.

た。[0005] Entangling of the paper fiber or paper chip around the inner edge of the chip causes writing defects such as faint writing or broken writing. Therefore, as shown in JP-A-9-122566, the edge S Was rounded by barrel processing to reduce scratches on the paper surface, but the dimensions of the tip of the chip after processing were not constant,
Also, if the foremost fore-edge portion is small in thickness and width, the foremost fore-edge portion is worn due to repeated contact with the paper surface, and the ball cannot be held (ball fly). And other problems.
