いる。The rear end wall of the inner hole of the tail plug (6) is provided with a hole (7) that is pulled out from the inner hole to the rear end at an appropriate position, and a boss (9) having a notch (8) is formed inside the rear end wall. The rear end of the ink filling portion (4) which is formed and has the ink contained in the batting substantially abuts. Further, the hole (7) is in close contact with the rear end surface of the shaft (5) in a closed state to block air flow from the ink filling section (4).

A cylindrical tail plug (10) is fitted to the outer peripheral portion of the rear end of the shaft (5) filled with ink. A shaft portion (1) is integrally erected from a rear end wall of the inner hole (15) of the tail plug (10), and a ring-shaped rib (1) is provided at an appropriate position on the outer peripheral portion of the shaft portion (13).
4) is formed, and a notch (12) is formed at the tip thereof so that the rear end of the ink filling portion (4) substantially abuts and the rib (14) is formed.
Is tightly fitted in the rear end hole of the shaft (5). Further, the rear end wall of the inner hole located between the inner wall of the tail plug (10) and the outer periphery of the shaft portion (13) is provided with holes (11) penetrating to the rear end at appropriate places. . Therefore, the air flow between the hole (11) and the ink filling section (4) is blocked.

As shown in the figure, when the shaft is fitted to the rear end of the shaft, air flow between the holes (7) and (11) communicating with the outside air and the ink filling portion (4) is blocked, and ink evaporation is prevented. Further, when the tail plug is pulled out from the shaft, the vent holes extending from the front end to the rear end are in communication with each other, so that the air flows.

Even if an infant holds the shaft in his mouth and accidentally swallows the tail plug, he / she will swallow it from the tip of the tail plug even if it is blocked in the throat or bronchus. Since the vent holes leading to the rear end communicate with each other, air circulation is performed, and a danger such as suffocation can be avoided.
