時に完全に満すものが得られていないのが実情で
ある。 The refill of a ballpoint pen that uses water-based ink contains a batting that absorbs water-based ink inside, and when writing, this ink is transferred to the pen body and consumed, but the amount of air that is commensurate with the amount of ink consumed is enters the refill and is replaced with ink. For this reason, the refill is provided with a ventilation hole, and this ventilation hole is usually provided near the tip of the refill. This is because when the cap is fitted and the pen is placed in a pocket of clothing, the pen body will be in an upward position, so the vent holes should be placed above the batting to prevent ink from flowing out through the vent holes. On the other hand, when using a reflex writing instrument with a Catpress type writing instrument, the pen body is in a downward position when worn in a pocket.
If a ventilation hole is provided at the tip, ink will flow out from this hole, so it is necessary to provide it at the tail end. In addition, since the batting is housed in the tail end, ink would flow out more easily if a ventilation hole were directly punched in the tail end of the refill, unlike the tip. In addition, the gap between the inner surface of the barrel of the writing instrument and the outer surface of the refill body is small, so if a ventilation hole is provided on the side of the refill body and even a small amount of ink comes out from the outlet of this vent, this ink will flow into the inner surface of the refill barrel. There is a problem that it adheres and oozes out onto the outer surface of the writing instrument body. For this reason, attempts have been made to provide ventilation grooves in the tail plug that is fitted to the rear end of the refill, but the reality is that nothing that completely satisfies both breathability and liquid tightness has not been achieved. .
そこで本考案は、簡単な構造で通気性と液密性

ル用尾栓により達成される。 Therefore, the purpose of this invention is to provide a refill tail plug that has a simple structure, satisfies breathability and liquid tightness at the same time, and is suitable for a cap press type writing instrument. A radial partition wall is provided in the outer cylinder, and upper and lower annular projections that closely contact the inner peripheral surface of the refil outer cylinder are formed on the outer periphery of the main body above and below the partition wall, and the upper annular projection and the partition wall, and the partition wall and the lower circular projection are formed on the outer periphery of the main body above and below the partition wall. This is achieved by a tail plug for a refill of a writing instrument, which is characterized by having upper and lower ventilation holes spaced 180 degrees apart from each other between the annular protrusion and the annular protrusion.
以下に図面に示す実施例に基いて本考案を具体
的に説明する。 The present invention will be specifically described below based on embodiments shown in the drawings.

ルに伝達される。 In FIG. 1, the tip of the refill main body 11 has a small diameter, and a ballpoint pen tip 12 is fitted into the opening. A filling 13 is housed inside the refill main body 11, and the filling 13 is held under pinching pressure by the stopper 14 and the tail plug 10. This batting 13 is formed into a rod shape by aligning ultrafine fibers such as polyester, and has a large ink absorption capacity.The water-based ink absorbed by this batting passes through the relay core 15 and is absorbed into the chips 12. transmitted to the ball.
ここで尾栓１０は、第２図に示す様に、内部に

際に、両円環突起２，３がレフイール本体１１内

穿設されている。このため、レフイール本体１１
の内部は下部通気孔６→周回間隙４→上部通気孔
５を通つて外部に連通している。 As shown in FIG. 2, the tail plug 10 is a cylindrical body having a radial partition wall 1 provided therein, and this is fitted into the tail end opening of the refil main body 11. Here, an upper annular projection 2 is formed at a position above the partition wall 1 on the outer periphery of the tail plug 10, and a lower annular projection 3 is formed at a position below the partition wall 1. When fitted into the tail end opening of the refill body, both the annular projections 2 and 3 come into close contact with the inner surface of the refil main body 11. Therefore, a circumferential gap 4 is formed between both the annular projections 2 and 3. An upper ventilation hole 5 is formed between the upper annular projection 2 and the partition wall 1, and a lower ventilation hole 6 is formed between the partition wall 1 and the lower annular projection 3 at a distance of 180 degrees. For this reason, the refil main body 11
The inside communicates with the outside through the lower ventilation hole 6 → the circumferential gap 4 → the upper ventilation hole 5.
しかして、筆記によつて中綿１３内のインキが
減少すると等量の空気が前記の経路を通つてレフ

つ。そして、筆記具を逆向きにしたときにインキ
が尾栓１０内に落ちると、前記の経路を通つて外
部に出ようとする。しかしこの経路は両通気孔
５，６間に周回間隙４が存在するため全長が長
く、このためインキは外部まで到達しない。そし
て、仮にインキが前記の経路を通つて外部に出て
も、出口は尾栓１０の中央であつて、内容積も大
きいためインキは軸筒には付着せず、筆記具本体
の外表面ににじみ出ることがない。 When the ink in the filling 13 decreases due to writing, an equal amount of air enters the refill main body 11 through the above-mentioned path to keep the internal pressure constant. If the ink falls into the tail plug 10 when the writing instrument is turned in the opposite direction, it tries to exit through the above-mentioned path. However, the entire length of this path is long because the circumferential gap 4 exists between both the ventilation holes 5 and 6, and therefore the ink does not reach the outside. Even if the ink were to exit through the above-mentioned path, the outlet is at the center of the tail plug 10 and the internal volume is large, so the ink would not adhere to the barrel and ooze out onto the outer surface of the writing instrument body. Never.
この様に本考案は、２個の通気孔の間に周回間
隙を設けたので、簡単な構造で通気性と液密性と
を同時に満足させることができ、キヤツプレスの
ノツク式筆記具に適したレフイール用尾栓とする
ことができる。 In this way, the present invention has a circumferential gap between the two ventilation holes, so it can satisfy both breathability and liquid tightness with a simple structure, and is suitable for the notebook type writing instruments of the cartridge press. It can be used as a tail plug.
