Claims

[Scope of utility model registration request]

A tail plug is fitted into the rear end of the refill tube that has an ink storage body built in and a writing section at the front end, and the tail plug has a large diameter inner hole that opens on the front face facing the rear end surface of the ink storage body. A cylindrical portion is provided that stands up integrally with the inner hole, and a circumferential groove is provided on the outer circumference of the approximately central portion of the portion that is inserted into the tube, and a point in the circumferential groove communicates with the inner hole. A small-diameter horizontal hole is provided, and a vertical groove is provided on the outer surface that communicates with the circumferential groove and reaches the rear end of the tube, and a vent is provided at the rear end of the tube to communicate with outside air. An aqueous tube that is provided near the opening so as to cover the horizontal hole so as to allow ventilation between the inside and outside of the tube through the vent, vertical groove, circumferential groove, horizontal hole, and inner hole of the tail plug. Refills for writing instruments such as ballpoint pens.
