Claims

[Scope of Claim for Utility Model Registration] 1. A tail plug is inserted into the rear end of a refill tube that has an ink storage body built in and a writing section at the front end,
The tail plug is provided with a large-diameter inner hole that opens on the front face facing the rear end surface of the ink storage body, and a circumferential groove is provided on the outer circumference of the approximately central part of the part that is inserted into the tube. A small-diameter horizontal hole communicating with the inner hole is provided at one point of the groove, and a vertical groove is formed on the outer surface of the circumferential groove at a point remote from the horizontal hole with the front end communicating and the rear end reaching to the rear of the rear end of the tube. A refill for a writing instrument such as a water-based ballpoint pen, characterized in that the tail plug is provided with a vertical groove, a circumferential groove, a horizontal hole, and an inner hole to ventilate the inside and outside of the tube. 2. A refill for a writing instrument such as a water-based ballpoint pen as set forth in claim 1 of the utility model registration claim, which is provided with a serpentine groove in a position where the circumferential groove and the lateral hole communicate with each other such that the lateral hole is located at the bottom of the serpentine shape. 3. A refill for a writing instrument such as a water-based ballpoint pen as set forth in claim 2 of the utility model registration claim, in which a serpentine groove is provided at a position where the circumferential groove and the longitudinal groove communicate with each other.
