・作用
キャップ１を筆記具本体５のペン先側に装着する以前の状態（図１）において、内キャップ４がバネ４６により後方に付勢され、該内キャップ４の前端が第１の筒体２内周面の抜け止め突起２３に当接している。このとき、第１の筒体２の第１の通気孔２２外周の頂壁２１内面と弾性シール体４１とが非接触状態にあり、第１の通気孔２２は塞がれていない。それにより、第１の筒体２の内部のペン先５１が収容される空間は、窓孔４４、第１の通気孔２２、および第２の通気孔３２を通して外気と連通している。 In a state before the action cap 1 is attached to the pen tip side of the writing instrument body 5 (FIG. 1), the inner cap 4 is urged rearward by the spring 46, and the front end of the inner cap 4 is the first cylindrical body 2. It contacts the retaining protrusion 23 on the inner peripheral surface. At this time, the inner surface of the top wall 21 on the outer periphery of the first vent hole 22 of the first cylindrical body 2 and the elastic seal body 41 are not in contact with each other, and the first vent hole 22 is not blocked. Thereby, the space in which the pen tip 51 inside the first cylindrical body 2 is accommodated communicates with the outside air through the window hole 44, the first vent hole 22, and the second vent hole 32.

次に、キャップ１を筆記具本体５のペン先５１側に装着していくと、まず、筆記具本体５外面のペン先５１後方に位置する肩部５３が内キャップ４内面の段部４５に当接し、キャップの装着過程に従って、内キャップ４が前方に移動される。その後、図２に示すように、弾性シール体４１の前端の環状のシール部４２が第１の筒体２の頂壁３１内面に密接し、第１の通気孔２２が内側より塞がれると同時に、第１の筒体２の内周面の環状突起２４が筆記具本体５外周面の環状突起５２と乗り越えて気密嵌合する。それにより、キャップ内は、外部と通気が遮断される。 Next, when the cap 1 is attached to the pen tip 51 side of the writing instrument body 5, first, the shoulder portion 53 located behind the pen tip 51 on the outer surface of the writing instrument body 5 comes into contact with the step 45 on the inner surface of the inner cap 4. The inner cap 4 is moved forward in accordance with the cap mounting process. After that, as shown in FIG. 2, when the annular seal portion 42 at the front end of the elastic seal body 41 is in close contact with the inner surface of the top wall 31 of the first cylindrical body 2, the first vent hole 22 is closed from the inside. At the same time, the annular protrusion 24 on the inner peripheral surface of the first cylindrical body 2 gets over the annular protrusion 52 on the outer peripheral surface of the writing instrument body 5 and is airtightly fitted. Thereby, the inside of the cap is shut off from the outside.

本実施の形態の筆記具用キャップ１は、通気孔３２が、キャップ本体の頂壁３１を外部から見た際に文字形状の識別表示を構成し、通気孔３２よりなる識別表示を、キャップ本体の頂壁３１の略中央に設けたことにより、キャップ１の頂壁３１に大きな通気孔３２を開口させ十分な空気流通が可能となり、しかも、キャップ１の頂壁３１に外部から容易な識別が可能な識別表示を形成できる。また、通気孔３２を文字形状にしたことにより、通気孔が、一定幅を有する線状の孔で構成できるため、キャップ装着時、指で通気孔３２を塞ぐことを回避でき、キャップ内の加圧空気をペン先５１内や筆記具本体５内に侵入させること抑止できる。 In the writing instrument cap 1 of the present embodiment, the ventilation hole 32 constitutes a character-shaped identification display when the top wall 31 of the cap body is viewed from the outside, and the identification display made of the ventilation hole 32 is displayed on the cap body. By providing at the approximate center of the top wall 31, a large air hole 32 is opened in the top wall 31 of the cap 1 to allow sufficient air flow, and the top wall 31 of the cap 1 can be easily identified from the outside. A unique identification can be formed. In addition, since the vent hole 32 can be configured as a linear hole having a certain width by making the vent hole 32 into a letter shape, it is possible to avoid blocking the vent hole 32 with a finger when the cap is attached, It is possible to prevent the compressed air from entering the pen tip 51 or the writing instrument body 5.

本実施の形態の筆記具用キャップ１は、キャップ本体の側壁にクリップ３４を設け、クリップ３４を下にしてキャップ本体の頂壁３１を外部から視認した際、通気孔３２よりなる識別表示を構成する文字が正規の向きで読み取り可能に配置されることにより、クリップ３４の正面向きで立てて陳列された際、文字形状の識別表示を容易に識別できる。 The writing instrument cap 1 according to the present embodiment is provided with a clip 34 on the side wall of the cap body, and constitutes an identification display made of the vent holes 32 when the top wall 31 of the cap body is viewed from the outside with the clip 34 facing downward. By arranging the characters so as to be readable in the normal orientation, the character-shaped identification display can be easily identified when the characters are displayed in the front direction of the clip 34.

本実施の形態の筆記具用キャップ１は、第２の筒体３の頂壁３１がキャップ本体の頂壁を構成し、第２の通気孔３２が識別表示を構成してなることにより、十分な通気機能を備えた、文字形状の通気孔を自由に形成することができる。 The writing instrument cap 1 according to the present embodiment is sufficient because the top wall 31 of the second cylindrical body 3 constitutes the top wall of the cap body, and the second ventilation hole 32 constitutes the identification display. A character-shaped ventilation hole having a ventilation function can be freely formed.
