Description

本発明は、水性・油性の筆記具用インキ、化粧液、塗料、薬剤などといった液体（以下インキという）を収容する吸蔵体やインキタンクを内蔵し、筆記あるいは塗布することができる塗布具に関する。
尚、本発明において「前方」・「前端」とは塗布体側を指し、「後端」とは吸蔵体やインキタンク側を指し、「高圧時」とはキャップを取付けた状態で本体内の空気の圧力が大気圧と比べて高い状態を指し、「大気圧」とは、その時・その場所での大気の圧力を指す。 The present invention relates to an applicator that has a built-in occlusion body and ink tank for containing a liquid (hereinafter referred to as ink) such as water-based and oil-based ink for writing instruments, cosmetic liquid, paint, and medicine.
In the present invention, “front” and “front end” refer to the coated body side, “rear end” refers to the occlusion body and the ink tank side, and “high pressure” refers to the air in the main body with the cap attached. The atmospheric pressure is higher than the atmospheric pressure, and “atmospheric pressure” refers to the atmospheric pressure at that time and location.

冬場、屋外で使用していた筆記具にキャップを取付けて暖房のよくきいた室内に移した場合のように温度変化が大きいときや、低所で使用していた筆記具にキャップを取付けて航空機内や山岳地帯等の高所に移した場合のように気圧変化が大きいときは、インキ筒内の空気の圧力が大気圧より高い状態（高圧時）となり、この状態でキャップを取り外したとき、インキ筒内の圧力が一瞬で塗布体側から外部へ放出されることで、過剰のインキが塗布体に供給される不具合（以下、インキボタ落ち現象という）が生じていた。
そしてこのインキボタ落ち現象を解決するために、外部方向にのみ通気可能な逆止弁を配設することによって、インキ筒内の圧力上昇を外部に逃がすカートリッジインキ筒が既に知られている（例えば特許文献１参照）。 In winter, when the temperature change is large, such as when the cap is attached to a writing instrument used outdoors and moved to a well-heated room, or when the cap is attached to a writing instrument used in a low place, When the pressure change is large, such as when moving to a high place such as a mountainous area, the air pressure in the ink cylinder is higher than the atmospheric pressure (at high pressure). When the cap is removed in this state, the ink cylinder The internal pressure was released from the application body side to the outside in an instant, resulting in a problem that excess ink was supplied to the application body (hereinafter referred to as “ink bleed-off phenomenon”).
In order to solve this ink drop-off phenomenon, a cartridge ink cylinder that releases a pressure increase in the ink cylinder to the outside by arranging a check valve that can vent only in the external direction is already known (for example, patents). Reference 1).

実開昭６０−７５０８７号公報Japanese Utility Model Publication No. 60-75087

特許文献１のカートリッジインキ筒は、キャップを取り外した状態でインキ筒内の空気が膨張したとき、つまり筆記時にインキ筒内の空気が膨張したとき、ペン芯先端からインキがボタ落ちすることを確かに防止できる。
しかし、キャップを取付けた状態でインキ筒内の空気が膨張したときにキャップを取り外した場合は、未だインキボタ落ち現象が生じるものである。
また弱いバネで押圧された平面状の弁体やボール状の弁体を設けて逆止弁を構成しているため、構成が複雑で製造工程が煩雑となるばかりか、逆止弁の占有する場所が大きくなる不具合が生じていた。 In the cartridge ink cylinder of Patent Document 1, when the air in the ink cylinder expands with the cap removed, that is, when the air in the ink cylinder expands at the time of writing, it is sure that the ink drops from the tip of the pen core. Can be prevented.
However, if the cap is removed when the air in the ink cylinder expands with the cap attached, the ink spilling phenomenon still occurs.
In addition, since the check valve is configured by providing a flat valve body or a ball-shaped valve element pressed by a weak spring, the structure is complicated and the manufacturing process becomes complicated, and the check valve occupies it. There was a problem that the place became bigger.

上記の課題を解決するために完成された発明は、インキを内蔵した本体と、前記本体前端に保持される塗布体と、前記塗布体を覆い、前記本体と着脱自在に気密嵌合するキャップと、よりなる塗布具であって、前記本体のうち、前記インキと接触しない箇所に本体内と外気とを連通する通気孔を設け、少なくとも外周縁に接着面を有している内圧調整ラベルを、前記通気孔を覆うように貼付けて前記通気孔を閉鎖し、前記通気孔の周囲に凸部又は凹部を設けることで、前記通気孔の周囲の少なくとも一部に、前記内圧調整ラベルが接触しない非接触部を形成し、本体内圧力が所定圧に達したとき前記内圧調整ラベルの接着面の一部が剥離して通気孔から空気を放出し、本体内圧力が大気圧以下に減圧されたとき前記内圧調整ラベルの剥離箇所が再接着して通気孔を再び閉鎖することを特徴とする塗布具である。 The invention completed to solve the above problems includes a main body containing ink, an application body held at the front end of the main body, a cap that covers the application body and is detachably and airtightly fitted to the main body. An inner pressure adjustment label having an adhesive surface at least on the outer periphery, provided with a vent hole that communicates the inside of the main body and the outside air at a location that does not come into contact with the ink of the main body. The inner pressure adjustment label is not in contact with at least a part of the periphery of the vent hole by sticking the vent hole so as to cover the vent hole and closing the vent hole and providing a convex portion or a concave portion around the vent hole. When a contact portion is formed, and when the internal pressure of the main body reaches a predetermined pressure, a part of the adhesive surface of the internal pressure adjustment label is peeled off to release air from the vent, and the internal pressure of the main body is reduced to an atmospheric pressure or lower. Separation location of the internal pressure adjustment label Readhering an applicator, characterized in that to close the vent hole again.

本発明は、本体内と連通する通気孔に内圧調整ラベルを貼付しているため、本体内の空気が膨張した状態（高圧時）になっても、内圧調整ラベルの一部が剥離して本体内の圧力と大気圧とが均一になることによって、キャップを取り外した場合でも塗布体先端からインキがボタ落ちすることを防止できる。
また本体内の空気が放出されたのち、本体内の圧力が減圧に転じた時点で、前記内圧調整ラベルの剥離箇所が再接着して通気孔を再び閉鎖する。したがって本体内の圧力は大気圧以下となるため、キャップを取り外した場合でも塗布体先端からインキがボタ落ちすることはない。
また本発明の内圧調整ラベルは構成が単純で小さいため製造工程が簡易となるとともに、占有する場所も小さくすることができる。 In the present invention, since the internal pressure adjustment label is attached to the vent hole communicating with the inside of the main body, even if the air in the main body is in an expanded state (at high pressure), a part of the internal pressure adjustment label is peeled off. By making the internal pressure and the atmospheric pressure uniform, ink can be prevented from dropping from the tip of the coated body even when the cap is removed.
Further, after the air in the main body is released, when the pressure in the main body changes to a reduced pressure, the peeled portion of the internal pressure adjustment label is reattached and the vent hole is closed again. Accordingly, since the pressure in the main body is equal to or lower than the atmospheric pressure, even when the cap is removed, the ink does not fall off from the tip of the application body.
In addition, since the internal pressure adjustment label of the present invention is simple and small, the manufacturing process is simplified and the occupied area can be reduced.

（実施例１）
以下に、本発明の塗布具にかかる実施例につき、図１〜図３と共に説明する。
本体１は後端を閉じた筒体である。後端は一体成型によって予め閉じて成型してもよいし、尾栓等の別体で閉じてもよい。また内部のインキの消費状態を確認できるように透明または半透明の合成樹脂製のプラスチックを採用してもよい。 Example 1
Below, the Example concerning the applicator of this invention is demonstrated with FIGS. 1-3.
The main body 1 is a cylindrical body whose rear end is closed. The rear end may be closed and molded in advance by integral molding, or may be closed by a separate body such as a tail plug. Moreover, you may employ | adopt the plastic made from a transparent or semi-transparent synthetic resin so that the consumption state of an internal ink can be confirmed.

前記本体１の内部には、インキを内蔵したインキ吸蔵体２を収納する。該インキ吸蔵体２は、毛細間隙を備えるものであればよく、例えば繊維束の樹脂加工体、繊維束の熱融着加工体、フェルト加工体、フェルトのニードルパンチ加工体、合成樹脂の多孔質気泡体等の多孔質材料、または軸方向のインキ誘導路を有する合成樹脂の押出成型体等が挙げられる。その材質は、アクリル繊維、ポリエステル繊維等の合成繊維樹脂を使用できる。また、前記インキ吸蔵体２は、その外周面に合成樹脂フィルム等よりなる外皮を備える構成でもよい。   In the main body 1, an ink occlusion body 2 containing ink is accommodated. The ink occlusion body 2 only needs to have a capillary gap. For example, a fiber bundle resin processed body, a fiber bundle heat fusion processed body, a felt processed body, a felt needle punch processed body, and a synthetic resin porous body Examples thereof include a porous material such as a foam, or an extruded product of a synthetic resin having an ink guide path in the axial direction. The material can be a synthetic fiber resin such as acrylic fiber or polyester fiber. Further, the ink occlusion body 2 may be configured to have an outer skin made of a synthetic resin film or the like on the outer peripheral surface thereof.

前記インキ吸蔵体２に内蔵するインキは、水性・油性、染料系・顔料系の筆記具用インキ、化粧液、塗料、薬剤などといった液体を適宜採用することができる。   As the ink incorporated in the ink occlusion body 2, liquids such as water-based / oil-based, dye-based / pigment-based inks for writing instruments, cosmetic liquids, paints, and drugs can be appropriately employed.

前記本体１の前端に塗布体３を保持する。
前記塗布体３は、例えばアクリル繊維・ポリエステル繊維・ナイロン繊維・ビニロン繊維を原料とし、該原料を樹脂で固めた繊維質塗布体や、合成樹脂の多孔質気泡体等の多孔質塗布体を使用できる。 An application body 3 is held at the front end of the main body 1.
The coated body 3 is made of, for example, a fibrous coated body made of, for example, acrylic fiber, polyester fiber, nylon fiber, or vinylon fiber, and the material is solidified with a resin, or a porous coated body such as a porous foam body of a synthetic resin. it can.

前記本体１と着脱自在にキャップ４を気密嵌合する。該キャップ４は前記塗布体３を覆い隠すように前記本体１の外周面と気密嵌合する。   A cap 4 is airtightly detachably attached to the main body 1. The cap 4 is airtightly fitted to the outer peripheral surface of the main body 1 so as to cover the application body 3.

前記本体１には、本体内と外気とを連通する通気孔５を設ける。該通気孔５は前記本体１の外壁に孔をあけて設ける。前記通気孔５は前記本体１に収納したインキ吸蔵体２と接触しない位置に設ける。
前記通気孔５の形状は、円形状・楕円形状、三角形・四角形等の多角形などを適宜採用可能であり、その個数は１個でも多数個でもよい。
また前記通気孔５の大きさは、後述の内圧調整ラベル６より少なくとも小さくする。該内圧調整ラベル６より小さければ前記通気孔５の大きさは適宜採用可能であるが、できる限り小さくすることが好ましい。円形状とした場合は直径０．５ｍｍ〜３．０ｍｍ程度とすることが好ましい。 The main body 1 is provided with a vent hole 5 for communicating the inside of the main body with the outside air. The vent hole 5 is provided by making a hole in the outer wall of the main body 1. The vent hole 5 is provided at a position where it does not come into contact with the ink storage body 2 stored in the main body 1.
As the shape of the vent hole 5, a circular shape, an elliptical shape, a polygonal shape such as a triangle or a quadrangle, and the like can be adopted as appropriate, and the number thereof may be one or many.
The size of the vent hole 5 is at least smaller than an internal pressure adjustment label 6 described later. If it is smaller than the internal pressure adjusting label 6, the size of the vent hole 5 can be adopted as appropriate, but it is preferable to make it as small as possible. In the case of a circular shape, the diameter is preferably about 0.5 mm to 3.0 mm.

前記通気孔５を覆うように内圧調整ラベル６を貼付けて前記通気孔５を閉鎖する。ここで閉鎖するとは、本体内と外気との連通を閉ざすことを意味する。
該内圧調整ラベル６はインキの蒸発を防ぐ材質であれば特に限定されないが、例えば、ポリエチレン・ポリプロピレン・ポリエチレンテレフタレート（ＰＥＴ）など合成樹脂の単層・多層フィルムやアルミ（金属）蒸着フィルムを採用することができる。
該内圧調整ラベル６のうち、前記通気孔５と対向させる面の少なくとも外周縁に接着剤を塗布して接着面を形成する。ここで外周縁とは、該内圧調整ラベルの外側の縁の一周部分をいう。接着面を形成する部分は、前記外周縁を含む全面でもよいし、内面部分を残した外周縁だけでもよい。
同一の接着剤を使用する場合、接着面の形成形態（接着面の面積）によって接着面の接着力は調整できる。前記外周縁を含む全面に接着面を形成した場合（接着面の面積が大きい場合）は接着力を強くすることができ、内面部分を残した外周縁だけに接着面を形成した場合（接着面の面積が小さい場合）は接着力を弱くすることができる。ただしいずれの場合も、前記通気孔５を閉鎖するように形成し、本体内と外気との連通は閉ざす。
接着面の接着力の強弱は、接着面を剥離できる本体内圧力の値に反映する。接着面の接着力が高くなれば、接着面を剥離するために必要な本体内圧力の値は高くなり、反対に、接着面の接着力が低くなれば、接着面を剥離するために必要な本体内圧力の値は低くなる。したがって、希望する本体内圧力の設定値（以下、所定圧という）に応じて、該所定圧に達したときに接着面が剥離するよう接着面の接着力（接着面の面積）を種々設定できる。 An internal pressure adjustment label 6 is attached so as to cover the vent hole 5 and the vent hole 5 is closed. Closing here means closing communication between the inside of the main body and the outside air.
The internal pressure adjusting label 6 is not particularly limited as long as it is a material that prevents evaporation of the ink. For example, a single layer / multilayer film of synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate (PET), or an aluminum (metal) vapor deposition film is employed. be able to.
An adhesive surface is formed by applying an adhesive to at least the outer peripheral edge of the surface of the internal pressure adjustment label 6 that faces the vent hole 5. Here, the outer peripheral edge means a peripheral portion of the outer edge of the internal pressure adjustment label. The part that forms the bonding surface may be the entire surface including the outer peripheral edge or only the outer peripheral edge leaving the inner surface part.
When the same adhesive is used, the adhesive force of the adhesive surface can be adjusted depending on the form of formation of the adhesive surface (area of the adhesive surface). When the adhesive surface is formed on the entire surface including the outer peripheral edge (when the area of the adhesive surface is large), the adhesive force can be increased, and when the adhesive surface is formed only on the outer peripheral edge leaving the inner surface portion (adhesive surface) When the area is small), the adhesive force can be weakened. However, in any case, the vent hole 5 is formed to be closed, and the communication between the inside of the main body and the outside air is closed.
The strength of the adhesive force of the adhesive surface is reflected in the value of the internal pressure at which the adhesive surface can be peeled. If the adhesive force of the adhesive surface increases, the pressure value in the main body necessary to peel the adhesive surface increases. Conversely, if the adhesive force of the adhesive surface decreases, it is necessary to peel the adhesive surface. The value of the body pressure decreases. Therefore, according to a desired set value of the internal pressure of the main body (hereinafter referred to as a predetermined pressure), various adhesive forces (adhesive surface area) can be set so that the adhesive surface peels when the predetermined pressure is reached. .

該内圧調整ラベル６は、前記通気孔５と対向する面に接着剤を塗布して接着面を形成し、離型紙と貼り合せた状態で所定の刃型でカットして製造する。
前記接着面を形成する接着剤としては、本体内の圧力が所定圧に達したとき接着面の一部が剥離し、減圧に転じた時点で再接着する接着剤であれば適宜採用可能であるが、接着剤の種類によって接着力に強弱があるため、前記接着面の形成形態（接着面の面積）と合わせて最適の接着剤を選択することが望ましい。
接着剤の種類としては、熱硬化性樹脂接着剤・熱可塑性樹脂接着剤・エラストマ接着剤等の合成接着剤を使用できる。熱硬化性樹脂接着剤としては、フェノール樹脂・レゾルシン樹脂・フラン樹脂・尿素樹脂・メラミン樹脂・ポリエステル樹脂・ポリウレタン樹脂・エポキシ樹脂・シリコーン樹脂等を使用できる。また熱可塑性樹脂接着剤としては、ポリオレフィン系樹脂・ポリ酢酸ビニル・ポリビニルアルコール・ポリ塩化ビニル・ポリビニルブチラール・ポリアクリル酸エステル・ニトロセルロース・ポリカーボネイト樹脂、ポリビニルエーテル、ポリアミド系樹脂、ポリアセタール樹脂、ポリフッ化ビニリデン、塩化ビニル−酢酸ビニル共重合樹脂、エチレン−酢酸ビニル共重合体系樹脂等を使用できる。またエラストマ樹脂接着剤としては、ブタジエンアクリロニトリルゴム・ネオプレン等を使用できる。
また、材質・形状の異なる複数種類の内圧調整ラベル６を用意すれば、インキ吸蔵体２に内蔵するインキの種類に応じて最適な内圧調整ラベル６を選択して採用することができ、本体１を何ら変更することなく汎用性のある安価な塗布具とすることができる。
また前記内圧調整ラベル６は前記インキと接触しないため、前記接着面を介してインキが外部へ漏れ出すことはない。 The internal pressure adjustment label 6 is manufactured by applying an adhesive to the surface facing the vent hole 5 to form an adhesive surface, and cutting it with a predetermined blade shape in a state of being bonded to the release paper.
As the adhesive for forming the adhesive surface, any adhesive can be used as long as it is a part of the adhesive surface that is peeled off when the pressure in the main body reaches a predetermined pressure and re-adhered when the pressure is reduced. However, since the adhesive strength varies depending on the type of adhesive, it is desirable to select an optimal adhesive in accordance with the formation form of the adhesive surface (area of the adhesive surface).
As the type of adhesive, a synthetic adhesive such as a thermosetting resin adhesive, a thermoplastic resin adhesive, and an elastomer adhesive can be used. As the thermosetting resin adhesive, phenol resin, resorcin resin, furan resin, urea resin, melamine resin, polyester resin, polyurethane resin, epoxy resin, silicone resin and the like can be used. Thermoplastic resin adhesives include polyolefin resin, polyvinyl acetate, polyvinyl alcohol, polyvinyl chloride, polyvinyl butyral, polyacrylate ester, nitrocellulose, polycarbonate resin, polyvinyl ether, polyamide resin, polyacetal resin, polyfluoride. Vinylidene, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin and the like can be used. As the elastomer resin adhesive, butadiene acrylonitrile rubber, neoprene or the like can be used.
If a plurality of types of internal pressure adjustment labels 6 of different materials and shapes are prepared, the optimum internal pressure adjustment label 6 can be selected and used according to the type of ink incorporated in the ink occlusion body 2. The applicator can be a versatile and inexpensive applicator without any change.
Further, since the internal pressure adjusting label 6 does not come into contact with the ink, the ink does not leak to the outside through the adhesive surface.

ここで、本体１、キャップ４の材質には合成樹脂製のプラスチックを使用することができる。   Here, a plastic made of synthetic resin can be used as the material of the main body 1 and the cap 4.

本実施例は以上のような構成であり、次にその作用について詳細に説明する。
インキを内蔵した本体内の空気が膨張し、本体内の圧力が所定圧に達したとき、内圧調整ラベル６の接着面の一部が剥離して通気孔５から本体内の空気を放出することで、本体内の圧力と大気圧とが均一となる。
また本体内の空気が放出されたのち、本体内の圧力が減圧に転じた時点で、前記内圧調整ラベル６の剥離箇所が再接着して通気孔５を再び閉鎖する。
したがって本体内の圧力は大気圧以下となるため、キャップを取り外した場合でも塗布体３先端からインキがボタ落ちすることはない。 The present embodiment is configured as described above, and the operation thereof will be described in detail next.
When the air in the main body containing ink expands and the pressure in the main body reaches a predetermined pressure, a part of the adhesive surface of the internal pressure adjustment label 6 is peeled off to release the air in the main body from the vent hole 5. Thus, the pressure in the main body and the atmospheric pressure become uniform.
Further, after the air in the main body is released, when the pressure in the main body is changed to a reduced pressure, the peeled portion of the internal pressure adjusting label 6 is reattached and the vent hole 5 is closed again.
Therefore, since the pressure in the main body is equal to or lower than the atmospheric pressure, even when the cap is removed, the ink does not fall off from the tip of the application body 3.

（実施例２）
以下に、本発明の塗布具にかかる実施例につき、図４〜図６と共に説明する。ここでは、前記した実施例とは異なる点のみを説明する。
前記通気孔５の周囲に凸部５１（図５参照）又は凹部５２（図６参照）を設けることで、前記通気孔５の周囲の少なくとも一部に前記内圧調整ラベル６が接触しない非接触部５３を形成する。該非接触部５３は気体のみが存在する空間である。凹部５２を設けた場合は凹部５２自身が非接触部５３となる。前記凸部５１及び凹部５２の断面形状は、円形状・楕円形状、三角形・四角形等の多角形などを適宜採用可能であり、その個数は一個でも多数個でもよい。ただしいずれの場合も内圧調整ラベル６を貼付けた際、前記通気孔５を閉鎖できるように形成する。
前記外周縁を含む全面に接着面を形成した内圧調整ラベル６（接着面の面積が大きい場合）であっても、前記凸部５１又は凹部５２の形成形態によって非接触部５３の表面積を調整することで内圧調整ラベル６の接着力も調整できる。前記非接触部５３の表面積を小さく形成した場合は接着力を強くすることができ、前記非接触部５３の表面積を大きく形成した場合は接着力を弱くすることができる。つまり、前記通気孔５の周囲に凸部５１又は凹部５２を設けると、前記内圧調整ラベル６の接着面の形成形態（接着面の面積）を変更しなくても接着力を調整することができるため、前記外周縁を含む全面に接着面を形成した生産性の高い内圧調整ラベル６を採用することができて都合がよい。
また、希望する本体内圧力の設定値（以下、所定圧という）に応じて、該所定圧に達したときに接着面が剥離するよう非接触部５３の表面積を種々設定できることは前記の通りであり、本実施例ではさらに、前記非接触部５３が空間（気体のみが存在する）であるため、温度による該空間の気体の体積増加によって接着面の剥離を補完することもできるものである。 (Example 2)
Below, the Example concerning the applicator of this invention is demonstrated with FIGS. 4-6. Here, only differences from the above-described embodiment will be described.
By providing a convex portion 51 (see FIG. 5) or a concave portion 52 (see FIG. 6) around the vent hole 5, the non-contact portion where the internal pressure adjustment label 6 does not contact at least a part around the vent hole 5. 53 is formed. The non-contact portion 53 is a space where only gas exists. When the recess 52 is provided, the recess 52 itself becomes the non-contact portion 53. As the cross-sectional shape of the convex portion 51 and the concave portion 52, a circular shape, an elliptical shape, a polygonal shape such as a triangle or a quadrangle, etc. can be adopted as appropriate, and the number thereof may be one or many. However, in any case, when the internal pressure adjustment label 6 is affixed, the vent hole 5 can be closed.
Even in the case of the internal pressure adjustment label 6 in which the adhesive surface is formed on the entire surface including the outer peripheral edge (when the area of the adhesive surface is large), the surface area of the non-contact portion 53 is adjusted by the formation form of the convex portion 51 or the concave portion 52. Thereby, the adhesive force of the internal pressure adjustment label 6 can also be adjusted. When the surface area of the non-contact portion 53 is formed small, the adhesive force can be increased, and when the surface area of the non-contact portion 53 is formed large, the adhesive force can be decreased. That is, when the convex portion 51 or the concave portion 52 is provided around the vent hole 5, the adhesive force can be adjusted without changing the form of formation of the adhesive surface of the internal pressure adjustment label 6 (area of the adhesive surface). Therefore, it is possible to employ the highly productive internal pressure adjusting label 6 in which an adhesive surface is formed on the entire surface including the outer peripheral edge.
Further, as described above, the surface area of the non-contact portion 53 can be variously set according to a desired set value of the internal pressure of the main body (hereinafter referred to as a predetermined pressure) so that the adhesive surface peels when the predetermined pressure is reached. In addition, in this embodiment, since the non-contact portion 53 is a space (only gas exists), peeling of the adhesive surface can be supplemented by an increase in the volume of gas in the space due to temperature.

In the case of different diameter shapes, it is easy to combine the diameters of the application body 3 and the ink occluding body 2 in various ways.
The application body holding portion 81 holds the application body 3 by press-fitting to the inner wall surface thereof. The application body holding portion 81 is provided with an ink communication hole 82 and an air flow path 83.

前記インキ連通孔８２は、塗布体保持部８１壁面を貫通させた貫通孔で、前記空気流路８３と分離して設ける。塗布体保持部８１の内壁面に前記塗布体３を保持すると、前記インキ連通孔８２は前記塗布体３の側面のみと連通するように構成される。このとき、インキ連通孔８２は前記インキ吸蔵体２と当接しないように構成する。

The size of the ink communication hole 82 is not limited as long as the air flow path 83 that connects the front end of the inner cylinder and the rear end of the application body holding portion is secured, but is 0 when water-based ink is used. .7Mm 2 range ～28Mm 2 is preferably in the range of 0.7mm 2 ~15mm 2 when employing the oil-based ink is preferable. When the ink communication hole 82 has a circular shape, in order to secure this preferable range, a diameter of 1.0 mm to 6.0 mm is employed when water-based ink is employed, and a diameter of 1.0 mm to 4.5 mm when oil-based ink is employed.

If it exists in this more preferable range, it can prevent more effectively that ink is supplied to the application body 3 excessively.
Further, the although the number of the ink passage 82 may suitably be applied from one to several, set by the number, such as the sum of the size of the ink passage 82 is in the range of 0.7mm 2 ~140mm 2 Then preferably, more and more preferable to set at the number that the range of 5mm 2 ~75mm 2. If it is in this preferable range, it can prevent more effectively that ink is supplied to the application body 3 excessively.
Further, the position where the ink communication hole 82 is provided may be provided anywhere on the wall surface of the application body holding portion 81 as long as it does not contact the ink occluding body 2. When there are a plurality of ink communication holes 82, they may be provided in a messy manner, or may be provided regularly and regularly so as to face each other. In order to provide them in an orderly manner, for example, the ink communication holes 82 may be provided at equal intervals on the wall surface of the application body holding portion 81.
Here, as shown in FIG. 7, it is more preferable that the two ink communication holes 82 are provided to face each other so as to face each other. In this way, the ink flows out from one ink communication hole 82 to the coated body 3 and the air flows from the other ink communication hole 82 opposite to each other. Can be done.

また、前記空気流路８３は、前記内筒８前端と前記塗布体保持部後端とを連通するように、前記塗布体保持部８１と前記塗布体３との間に、前記内筒８前端から前記塗布体保持部後端までの全長にわたって溝状に形成される。前記空気流路８３の大きさや数に特に制限はない。
ここで、本発明において分離するとは「分けて離すこと」を意味し、本発明では、インキ連通孔８２と空気流路８３とが接することや交わることなく離して設けられることを意味し、また連通するとは塗布体３とインキタンク１０との間をインキが自由に流通できることを意味する。 In addition, the air flow path 83 has a front end of the inner cylinder 8 between the application body holding part 81 and the application body 3 so as to communicate the front end of the inner cylinder 8 and the rear end of the application body holding part. To the rear end of the applicator holding part. There is no particular limitation on the size and number of the air flow paths 83.
Here, separating in the present invention means “separating and separating”, and in the present invention, it means that the ink communication hole 82 and the air flow path 83 are provided apart from each other without being in contact with each other. The term “communication” means that ink can freely flow between the application body 3 and the ink tank 10.

前記内筒８に収納した前記インキ吸蔵体２は、毛細間隙を備えるものであればよく、例えば繊維束の樹脂加工体、繊維束の熱融着加工体、フェルト加工体、フェルトのニードルパンチ加工体、合成樹脂の多孔質気泡体等の多孔質材料、または軸方向のインキ誘導路を有する合成樹脂の押出成型体等が挙げられる。その材質は、アクリル繊維、ポリエステル繊維等の合成繊維樹脂を使用できる。また、前記インキ吸蔵体２は、その外周面に合成樹脂フィルム等よりなる外皮を備える構成でもよい。   The ink occlusion body 2 accommodated in the inner cylinder 8 only needs to have a capillary gap. For example, a resin processed body of fiber bundles, a heat-bonded processed body of fiber bundles, a felt processed body, and needle punching of felt. Body, a porous material such as a porous foam of synthetic resin, or an extruded body of synthetic resin having an axial ink guide path. The material can be a synthetic fiber resin such as acrylic fiber or polyester fiber. Further, the ink occlusion body 2 may be configured to have an outer skin made of a synthetic resin film or the like on the outer peripheral surface thereof.

前記インキ吸蔵体２は、前記塗布体３の後端と接続される。ここで、前記塗布体３の密度をインキ吸蔵体２の密度より高く設定し、塗布体３の毛管力をインキ吸蔵体２の毛管力より高くする。
例えば、塗布体３として気孔率約６０％・ポリエステル繊維を採用し、インキ吸蔵体２として気孔率約８５％・ポリエステル繊維を採用した組み合わせが可能である。 The ink occlusion body 2 is connected to the rear end of the application body 3. Here, the density of the application body 3 is set higher than the density of the ink storage body 2, and the capillary force of the application body 3 is made higher than the capillary force of the ink storage body 2.
For example, a combination in which a porosity of about 60% and polyester fibers are employed as the application body 3 and a porosity of about 85% and polyester fibers is employed as the ink occlusion body 2 is possible.

先端部材９は、前端および後端が共に開口した筒状体で、前方に向かって縮径し、前方内周面と前記塗布体保持部８１の前端外周面が気密嵌合する。前記前方内周面の前端まで塗布体保持部８１が到達していてもよいし、前方内周面の途中まで塗布体保持部８１が到達していてもよい。図７、図８に示すように、前方内周面の途中まで到達している場合は、前記空気流路８３の連通を阻害しないように、前記先端部材９の前方内周面内にも前記空気流路２２と連通する空気流路を設ける必要がある。
また先端部材９後端は、前記外筒７の先端開口部と気密嵌合する。これにより、前記外筒７の内壁と前記内筒８の外壁と先端部材９によってインキタンク１０が形成される。
ここで、本発明において気密嵌合とは、気体の流通を妨げるように密閉し気圧の変化の影響を受けないように嵌合することを意味する。 The front end member 9 is a cylindrical body having both front and rear ends opened, and is reduced in diameter toward the front, and the front inner peripheral surface and the front end outer peripheral surface of the application body holding portion 81 are airtightly fitted. The applicator holding part 81 may reach the front end of the front inner peripheral surface, or the applicator holding part 81 may reach the middle of the front inner peripheral surface. As shown in FIG. 7 and FIG. 8, when reaching the middle of the front inner peripheral surface, the front member 9 also includes the front inner peripheral surface so as not to disturb the communication of the air flow path 83. It is necessary to provide an air flow path communicating with the air flow path 22.
The rear end of the tip member 9 is airtightly fitted to the tip opening of the outer cylinder 7. Thus, an ink tank 10 is formed by the inner wall of the outer cylinder 7, the outer wall of the inner cylinder 8, and the tip member 9.
Here, in the present invention, the airtight fitting means that the airtight fitting is performed so as to prevent the gas flow and the fitting is performed so as not to be affected by the change in the atmospheric pressure.

前記先端部材９と着脱自在にキャップ４を気密嵌合する。該キャップ４は前記塗布体３を覆い隠すように前記先端部材９の外周面と気密嵌合する。   The cap 4 is airtightly fitted to the tip member 9 in a detachable manner. The cap 4 is airtightly fitted to the outer peripheral surface of the tip member 9 so as to cover the application body 3.

前記インキタンク１０にはインキを収容する。本発明のインキとしては、水性・油性、染料系・顔料系の筆記具用インキ、化粧液、塗料、薬剤などといった液体を適宜採用することができる。   The ink tank 10 contains ink. As the ink of the present invention, liquids such as water-based / oil-based, dye-based / pigment-based inks for writing instruments, cosmetic liquids, paints, and drugs can be appropriately employed.

前記インキタンク１０からインキが流出できる場所は、前記塗布体保持部８１に設けた前記インキ連通孔８２からのみとなる。そして、前記インキ連通孔８２は前記塗布体３の側面のみと連通するように構成されているため、前記インキタンク１０からのインキは塗布体の側面のみと連通することになる。   The place where the ink can flow out from the ink tank 10 is only from the ink communication hole 82 provided in the application body holding portion 81. Since the ink communication hole 82 is configured to communicate only with the side surface of the application body 3, the ink from the ink tank 10 communicates only with the side surface of the application body.

前記本体１には、本体内と外気とを連通する通気孔５を設ける。該通気孔５は前記本体１の外壁に孔をあけて設ける。前記通気孔５は前記本体１に収納したインキ吸蔵体２と接触しない位置に設ける。
前記通気孔５の形状は、円形状・楕円形状、三角形・四角形等の多角形などを適宜採用可能であり、その個数は１個でも多数個でもよい。
また前記通気孔５の大きさは、後述の内圧調整ラベル６より少なくとも小さくする。該内圧調整ラベル６より小さければ前記通気孔５の大きさは適宜採用可能であるが、できる限り小さくすることが好ましい。円形状とした場合は直径０．５ｍｍ〜３．０ｍｍ程度とすることが好ましい。 The main body 1 is provided with a vent hole 5 for communicating the inside of the main body with the outside air. The vent hole 5 is provided by making a hole in the outer wall of the main body 1. The vent hole 5 is provided at a position where it does not come into contact with the ink storage body 2 stored in the main body 1.
As the shape of the vent hole 5, a circular shape, an elliptical shape, a polygonal shape such as a triangle or a quadrangle, and the like can be adopted as appropriate, and the number thereof may be one or many.
The size of the vent hole 5 is at least smaller than an internal pressure adjustment label 6 described later. If it is smaller than the internal pressure adjusting label 6, the size of the vent hole 5 can be adopted as appropriate, but it is preferable to make it as small as possible. In the case of a circular shape, the diameter is preferably about 0.5 mm to 3.0 mm.

本実施例には、前記実施例１の内圧調整ラベル６を採用できる。
つまり、前記通気孔５を覆うように内圧調整ラベル６を貼付けて前記通気孔５を閉鎖する。ここで閉鎖するとは、本体内と外気との連通を閉ざすことを意味する。
該内圧調整ラベル６はインキの蒸発を防ぐ材質であれば特に限定されないが、例えば、ポリエチレン・ポリプロピレン・ポリエチレンテレフタレート（ＰＥＴ）など合成樹脂の単層・多層フィルムやアルミ（金属）蒸着フィルムを採用することができる。
該内圧調整ラベル６のうち、前記通気孔５と対向させる面の少なくとも外周縁に接着剤を塗布して接着面を形成する。ここで外周縁とは、該内圧調整ラベルの外側の縁の一周部分をいう。接着面を形成する部分は、前記外周縁を含む全面でもよいし、内面部分を残した外周縁だけでもよい。
同一の接着剤を使用する場合、接着面の形成形態（接着面の面積）によって接着面の接着力は調整できる。前記外周縁を含む全面に接着面を形成した場合（接着面の面積が大きい場合）は接着力を強くすることができ、内面部分を残した外周縁だけに接着面を形成した場合（接着面の面積が小さい場合）は接着力を弱くすることができる。ただしいずれの場合も、前記通気孔５を閉鎖するように形成し、本体内と外気との連通は閉ざす。
接着面の接着力の強弱は、接着面を剥離できる本体内圧力の値に反映する。接着面の接着力が高くなれば、接着面を剥離するために必要な本体内圧力の値は高くなり、反対に、接着面の接着力が低くなれば、接着面を剥離するために必要な本体内圧力の値は低くなる。したがって、希望する本体内圧力の設定値（以下、所定圧という）に応じて、該所定圧に達したときに接着面が剥離するよう接着面の接着力（接着面の面積）を種々設定できる。 In this embodiment, the internal pressure adjustment label 6 of the first embodiment can be adopted.
That is, the internal pressure adjustment label 6 is attached so as to cover the vent hole 5 and the vent hole 5 is closed. Closing here means closing communication between the inside of the main body and the outside air.
The internal pressure adjusting label 6 is not particularly limited as long as it is a material that prevents evaporation of the ink. For example, a single layer / multilayer film of synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate (PET), or an aluminum (metal) vapor deposition film is employed. be able to.
An adhesive surface is formed by applying an adhesive to at least the outer peripheral edge of the surface of the internal pressure adjustment label 6 that faces the vent hole 5. Here, the outer peripheral edge means a peripheral portion of the outer edge of the internal pressure adjustment label. The part that forms the bonding surface may be the entire surface including the outer peripheral edge or only the outer peripheral edge leaving the inner surface part.
When the same adhesive is used, the adhesive force of the adhesive surface can be adjusted depending on the form of the adhesive surface (area of the adhesive surface). When the adhesive surface is formed on the entire surface including the outer peripheral edge (when the area of the adhesive surface is large), the adhesive force can be increased, and when the adhesive surface is formed only on the outer peripheral edge leaving the inner surface portion (adhesive surface) When the area is small), the adhesive force can be weakened. However, in any case, the vent hole 5 is formed to be closed, and the communication between the inside of the main body and the outside air is closed.
The strength of the adhesive force of the adhesive surface is reflected in the value of the internal pressure at which the adhesive surface can be peeled off. If the adhesive force of the adhesive surface increases, the pressure value in the main body necessary to peel the adhesive surface increases. Conversely, if the adhesive force of the adhesive surface decreases, it is necessary to peel the adhesive surface. The value of the body pressure decreases. Therefore, according to a desired set value of the internal pressure of the main body (hereinafter referred to as a predetermined pressure), various adhesive forces (adhesive surface area) can be set so that the adhesive surface peels when the predetermined pressure is reached. .

該内圧調整ラベル６は、前記通気孔５と対向する面に接着剤を塗布して接着面を形成し、離型紙と貼り合せた状態で所定の刃型でカットして製造する。
前記接着面を形成する接着剤としては、本体内の圧力が所定圧に達したとき接着面の一部が剥離し、減圧に転じた時点で再接着する接着剤であれば適宜採用可能であるが、接着剤の種類によって接着力に強弱があるため、前記接着面の形成形態（接着面の面積）と合わせて最適の接着剤を選択することが望ましい。
接着剤の種類としては、熱硬化性樹脂接着剤・熱可塑性樹脂接着剤・エラストマ接着剤等の合成接着剤を使用できる。熱硬化性樹脂接着剤としては、フェノール樹脂・レゾルシン樹脂・フラン樹脂・尿素樹脂・メラミン樹脂・ポリエステル樹脂・ポリウレタン樹脂・エポキシ樹脂・シリコーン樹脂等を使用できる。また熱可塑性樹脂接着剤としては、ポリオレフィン系樹脂・ポリ酢酸ビニル・ポリビニルアルコール・ポリ塩化ビニル・ポリビニルブチラール・ポリアクリル酸エステル・ニトロセルロース・ポリカーボネイト樹脂、ポリビニルエーテル、ポリアミド系樹脂、ポリアセタール樹脂、ポリフッ化ビニリデン、塩化ビニル−酢酸ビニル共重合樹脂、エチレン−酢酸ビニル共重合体系樹脂等を使用できる。またエラストマ樹脂接着剤としては、ブタジエンアクリロニトリルゴム・ネオプレン等を使用できる。
また、材質・形状の異なる複数種類の内圧調整ラベル６を用意すれば、インキ吸蔵体２に内蔵するインキの種類に応じて最適な内圧調整ラベル６を選択して採用することができ、本体１を何ら変更することなく汎用性のある安価な塗布具とすることができる。
また前記内圧調整ラベル６は前記インキと接触しないため、前記接着面を介してインキが外部へ漏れ出すことはない。 The internal pressure adjustment label 6 is manufactured by applying an adhesive to the surface facing the vent hole 5 to form an adhesive surface, and cutting it with a predetermined blade shape in a state of being bonded to the release paper.
As the adhesive for forming the adhesive surface, any adhesive can be used as long as it is a part of the adhesive surface that is peeled off when the pressure in the main body reaches a predetermined pressure and re-adhered when the pressure is reduced. However, since the adhesive strength varies depending on the type of adhesive, it is desirable to select an optimal adhesive in accordance with the formation form of the adhesive surface (area of the adhesive surface).
As the type of adhesive, a synthetic adhesive such as a thermosetting resin adhesive, a thermoplastic resin adhesive, and an elastomer adhesive can be used. As the thermosetting resin adhesive, phenol resin, resorcin resin, furan resin, urea resin, melamine resin, polyester resin, polyurethane resin, epoxy resin, silicone resin and the like can be used. Thermoplastic resin adhesives include polyolefin resin, polyvinyl acetate, polyvinyl alcohol, polyvinyl chloride, polyvinyl butyral, polyacrylate ester, nitrocellulose, polycarbonate resin, polyvinyl ether, polyamide resin, polyacetal resin, polyfluoride. Vinylidene, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin and the like can be used. As the elastomer resin adhesive, butadiene acrylonitrile rubber, neoprene or the like can be used.
If a plurality of types of internal pressure adjustment labels 6 of different materials and shapes are prepared, the optimum internal pressure adjustment label 6 can be selected and used according to the type of ink incorporated in the ink occlusion body 2. The applicator can be a versatile and inexpensive applicator without any change.
Further, since the internal pressure adjusting label 6 does not come into contact with the ink, the ink does not leak to the outside through the adhesive surface.

また、本実施例には、前記実施例２の構成も採用できる。
つまり、前記通気孔５の周囲に凸部５１（図５参照）又は凹部５２（図６参照）を設けることで、前記通気孔５の周囲の少なくとも一部に前記内圧調整ラベル６が接触しない非接触部５３を形成する。該非接触部５３は気体のみが存在する空間である。凹部５２を設けた場合は凹部５２自身が非接触部５３となる。前記凸部５１及び凹部５２の断面形状は、円形状・楕円形状、三角形・四角形等の多角形などを適宜採用可能であり、その個数は一個でも多数個でもよい。ただしいずれの場合も内圧調整ラベル６を貼付けた際、前記通気孔５を閉鎖できるように形成する。
前記外周縁を含む全面に接着面を形成した内圧調整ラベル６（接着面の面積が大きい場合）であっても、前記凸部５１又は凹部５２の形成形態によって非接触部５３の表面積を調整することで内圧調整ラベル６の接着力も調整できる。前記非接触部５３の表面積を小さく形成した場合は接着力を強くすることができ、前記非接触部５３の表面積を大きく形成した場合は接着力を弱くすることができる。つまり、前記通気孔５の周囲に凸部５１又は凹部５２を設けると、前記内圧調整ラベル６の接着面の形成形態（接着面の面積）を変更しなくても接着力を調整することができるため、前記外周縁を含む全面に接着面を形成した生産性の高い内圧調整ラベル６を採用することができて都合がよい。
また、希望する本体内圧力の設定値（以下、所定圧という）に応じて、該所定圧に達したときに接着面が剥離するよう非接触部５３の表面積を種々設定できることは前記の通りであり、本実施例ではさらに、前記非接触部５３が空間（気体のみが存在する）であるため、温度による該空間の気体の体積増加によって接着面の剥離を補完することもできるものである。 Moreover, the structure of the said Example 2 is also employable for a present Example.
That is, by providing the convex portion 51 (see FIG. 5) or the concave portion 52 (see FIG. 6) around the vent hole 5, the internal pressure adjustment label 6 is not in contact with at least a part around the vent hole 5. A contact portion 53 is formed. The non-contact portion 53 is a space where only gas exists. When the recess 52 is provided, the recess 52 itself becomes the non-contact portion 53. As the cross-sectional shape of the convex portion 51 and the concave portion 52, a circular shape, an elliptical shape, a polygonal shape such as a triangle or a quadrangle, etc. can be adopted as appropriate, and the number thereof may be one or many. However, in any case, when the internal pressure adjustment label 6 is affixed, the vent hole 5 can be closed.
Even in the case of the internal pressure adjustment label 6 in which the adhesive surface is formed on the entire surface including the outer peripheral edge (when the area of the adhesive surface is large), the surface area of the non-contact portion 53 is adjusted by the formation form of the convex portion 51 or the concave portion 52. Thereby, the adhesive force of the internal pressure adjustment label 6 can also be adjusted. When the surface area of the non-contact portion 53 is formed small, the adhesive force can be increased, and when the surface area of the non-contact portion 53 is formed large, the adhesive force can be decreased. That is, when the convex portion 51 or the concave portion 52 is provided around the vent hole 5, the adhesive force can be adjusted without changing the form of formation of the adhesive surface of the internal pressure adjustment label 6 (area of the adhesive surface). Therefore, it is possible to employ the highly productive internal pressure adjusting label 6 in which an adhesive surface is formed on the entire surface including the outer peripheral edge.
Further, as described above, the surface area of the non-contact portion 53 can be variously set according to a desired set value of the internal pressure of the main body (hereinafter referred to as a predetermined pressure) so that the adhesive surface peels when the predetermined pressure is reached. In addition, in this embodiment, since the non-contact portion 53 is a space (only gas exists), peeling of the adhesive surface can be supplemented by an increase in the volume of gas in the space due to temperature.

ここで、外筒７、内筒８、先端部材９の材質には合成樹脂製のプラスチックを使用することができる。   Here, plastics made of synthetic resin can be used for the material of the outer cylinder 7, the inner cylinder 8 and the tip member 9.

本実施例は以上のような構成であり、次にその作用について詳細に説明する。
本実施例の塗布具は、組立てたとき、塗布体保持部８１に設けられたインキ連通孔８２から塗布体３にインキは流出する。このインキの流出によってインキタンク１０にはインキが減少した分の空気が塗布体３より同時に流入し、インキタンク１０と塗布体３の間でインキと空気の置換が行われる。そして、インキタンク１０への空気の流入と塗布体３へのインキの流出が平衡に達した時点でインキ連通孔８２を通じた塗布体３へのインキの流出は停止する。
そして、塗布体３に流出したインキが筆記あるいは塗布によって消費されると、外気が塗布体３を通ってインキ連通孔８２よりインキタンク１０内に流入し、その際これと入れ替わってインキがインキ連通孔８２を通って塗布体３へ流出し、インキがインキ連通孔８２を閉塞する位置に到達するまで流出すると、空気はもはやインキ連通孔８２を通過することが不可能となり、その結果塗布体３内へのインキの流出は停止する。このように、インキ連通孔８２はインキおよび空気の流通のバルブ機能を有するもので、インキが過剰に塗布体３に供給されることを防止し、常に一定量のインキを塗布体３に供給する役目をする。すなわち空気の流入量分だけインキが塗布体３へ流出することになる。 The present embodiment is configured as described above, and the operation thereof will be described in detail next.
When the applicator of this embodiment is assembled, ink flows out from the ink communication hole 82 provided in the applicator holding portion 81 to the applicator 3. Due to the outflow of ink, air corresponding to the reduced amount of ink flows into the ink tank 10 simultaneously from the applying body 3, and the ink and air are replaced between the ink tank 10 and the applying body 3. Then, when the inflow of air into the ink tank 10 and the outflow of ink into the application body 3 reach equilibrium, the outflow of ink to the application body 3 through the ink communication holes 82 stops.
Then, when the ink that has flowed out to the application body 3 is consumed by writing or application, the outside air flows into the ink tank 10 through the ink communication hole 82 through the application body 3, and in this case, the ink is exchanged and the ink is communicated with the ink. When the ink flows out through the hole 82 to the applicator 3 and reaches the position where the ink communication hole 82 is blocked, the air can no longer pass through the ink communication hole 82, and as a result, the applicator 3. Ink flow stops inside. In this way, the ink communication hole 82 has a valve function for the flow of ink and air, prevents ink from being excessively supplied to the application body 3, and always supplies a constant amount of ink to the application body 3. To play a role. That is, the ink flows out to the application body 3 by the amount of air flowing in.

次に、キャップ４を取付けて、本体１内およびインキタンク１０内の空気が膨張した状態（高圧時）について説明する。
この状態で本体１内およびインキタンク１０内の内圧が所定圧力に達したとき、本体１内の空気およびインキタンク１０内の空気によって押し出された空気は、内圧調整ラベル６の接着面の一部が剥離することで通気孔５を通じて外気に排出される。そのため、本体１内およびインキタンク１０内の圧力は大気圧以下となるため、キャップ４を取り外したとき塗布体３先端からインキがボタ落ちすることはない。
その後、本体１内およびインキタンク１０内の空気が収縮したときは、本体１内の内圧が減圧に転じた時点で、前記内圧調整ラベル６の剥離箇所が再接着して通気孔５を再び閉鎖する。 Next, a state where the cap 4 is attached and the air in the main body 1 and the ink tank 10 is expanded (at high pressure) will be described.
In this state, when the internal pressure in the main body 1 and the ink tank 10 reaches a predetermined pressure, the air in the main body 1 and the air pushed out by the air in the ink tank 10 are part of the adhesive surface of the internal pressure adjustment label 6. Is released to the outside air through the vent hole 5. Therefore, since the pressure in the main body 1 and the ink tank 10 is equal to or lower than atmospheric pressure, the ink does not fall off from the tip of the application body 3 when the cap 4 is removed.
Thereafter, when the air in the main body 1 and the ink tank 10 contracts, when the internal pressure in the main body 1 changes to a reduced pressure, the peeled portion of the internal pressure adjustment label 6 is reattached and the vent hole 5 is closed again. To do.
