【発明の属する技術分野】
本発明は、マーカー、水性インキペン、水性ボ−ルペン、修正ペン、蛍光ペンその他の蒸発しやすい筆記成分を含む筆記体を有する筆記具に関し、特にキャップにより気密構造が得られるようにしたキャップ式エアタイト筆記具に係るものである。
【0002】
【従来の技術】
マーカー等の筆記具は、不使用時に筆記先端が乾燥しないようキャップやキャップレス式による適宜の密封装置で気密に保持されている。通常、キャップ式の場合、筆記体を収納した軸筒の先端に着脱可能にキャップを取り付け、該キャップを装着したときに筆記先端を取り囲む気密室が形成されるようにしたり、該筆記先端にゴムブッシュ等の弾性体が当接して密封するように構成されている。また、キャップレス式の場合は、筆記体(リフィール)が前進するときに先端開口部を開き、後退するときに該先端開口部が閉じるようばね等の弾性部材を用いた気密構造が知られている。
【0003】
しかし、従来のキャップ式の場合には、使用の際にキャップを取り外してから筆記をしなければならない煩わしさがあり、キャップレス式の場合には部品点数が多く、組立が面倒で経済的に得られず、製品が太径になる傾向にあった。
【0004】
【発明が解決しようとする課題】
本発明の解決課題は、使用の際にキャップを取り外す必要がなく、ひとつの動作で筆記体(リフィール)の出没、気密保持が可能なキャップ式エアタイト筆記具を提供することである。
【0005】
【課題を解決するための手段】
発明によれば、先端に形成した通孔から筆記体の筆記先端が突出する筆記位置と該筆記先端が内方に収納される収納位置に移動できるようキャップを筆記体に嵌着し、該キャップ内に上記筆記先端を取り囲むエアタイトスリーブを所定範囲内で前後に移動可能に挿入し、該エアタイトスリーブの後部に該エアタイトスリーブが後退位置にあるとき筆記体の首部に気密的に嵌合するよう嵌合部を設け、該嵌合部と筆記体の首部の嵌合は該エアタイトスリーブが前進位置にあるとき離脱可能であり、該エアタイトスリーブの前部に傾斜開口縁を有する開口部と該傾斜開口縁に密着するようヒンジを介して上記開口部に開閉可能に連結した蓋体を形成し、該蓋体の背面に該エアタイトスリーブが後退位置に移動するとき上記キャップの内面に当って該蓋体を上記傾斜開口縁に圧着するよう押圧リブを形成し、上記キャップの側面に上記エアタイトスリーブが前進位置に移動するとき上記蓋体の開放を許容するよう上記押圧リブが嵌入する窓孔を形成したキャップ式エアタイト筆記具が提供され、上記課題が解決される。
【0006】
上記キャップは筆記体の先部に軸方向に移動可能に設けられ、筆記先端が外方に突出する筆記位置から収納位置に向けてキャップを移動させると、移動の途中でエアタイトスリーブの嵌合部と筆記体の首部が嵌合し、エアタイトスリーブが後退位置に向けて移動し、押圧リブによって蓋体が傾斜開口縁に圧着され、該エアタイトスリーブの開口部が閉鎖されて、上記筆記先端の周囲を気密的に包囲し、上記キャップは収納位置に保持され、上記筆記先端の乾燥は防止される。
【0007】
上記収納位置から筆記位置に向けてキャップを移動させると、上記エアタイトスリーブは上記筆記体の首部に嵌合部が嵌合した状態で前進位置に移動し、その後上記筆記体の首部と嵌合部の嵌合が外れ、上記押圧リブがキャップの窓孔に対向したとき該窓孔に嵌入すると共に蓋体は開放され、上記キャップは筆記位置に保持され、上記筆記体は筆記先端が通孔から突出して筆記することができる。
【0008】
【発明の実施の形態】
図1,図2を参照し、筆記体(リフィール)(1)の前部には、軸方向に移動可能にキャップ(2)が取り付けられている。該キャップ(2)は、プラスチック材料で作られ、上記筆記体(1)の筆記先端(3)が内方に収納される収納位置(図1)と筆記先端(3)がキャップの先端に形成した通孔(4)から突出する筆記位置(後記図6)の間を移動する。図に示す実施例では、上記キャップ(2)は筆記体(1)の軸方向にスライドさせて移動できるようにしてあるが、該キャップを筆記体にねじ係合させて螺旋運動により軸方向に移動できるようにしてもよい(図示略)。
【0009】
上記筆記体(1)の太径部(5)の外周には、ロック部(6)を形成してあり、これに対応して上記キャップ(2)内には該ロック部(6)が筆記位置及び収納位置でそれぞれ係合するよう係合部(7),(8)を設けてある。上記キャップ(2)は、係合部(7)がロック部(6)に係合することにより収納位置に保持され、上記係合部(8)がロック部(6)に係合することにより筆記位置に保持される。
【0010】
上記キャップ(2)内には、上記筆記先端(3)を取り囲むよう図4に示すように、外面が略角筒状で内面が略円筒状に形成されたエアタイトスリーブ(9)が挿入されており、該エアタイトスリーブ(9)は、所定範囲内、すなわち前進位置及び後退位置間で前後に移動可能である。
【0011】
上記エアタイトスリーブ(9)の後部には、上記筆記体(1)の首部(10)に気密的に嵌合する嵌合部(11)が設けられている。該嵌合部(11)と首部(10)の嵌合は、該エアタイトスリーブ(9)が前進位置で停止しているとき、該エアタイトスリーブ(9)と筆記体(1)を相対的に軸方向に近づける方向に移動させると外すことができる程度に、離脱可能に嵌合している。
【0012】
上記エアタイトスリーブ(9)の前部には、上記筆記体(1)の筆記先端(3)を挿通させることができるよう開口部(12)が形成され、該開口部(12)の前面は軸芯に対して約60°以下、好ましくは約45°程度の角度で傾斜する傾斜開口縁(13)となっている。また、該開口部(12)の内方端には、ヒンジ(14)を介して開閉可能に蓋体(15)が連結されている。該ヒンジ(14)は、図4に示すように、蓋体(15)の幅方向に延び、該蓋体(15)を的確に傾斜開口縁(13)に密着させる。
【0013】
上記蓋体(15)の背面には、上記エアタイトスリーブ(9)が後退位置に移動するとき、上記キャップ(2)の内面(16)に当って該蓋体(15)を回動させ、上記傾斜開口縁(13)に圧着するよう押圧リブ(17)が設けられている。該押圧リブ(17)は適宜の形状に形成してもよいが、図に示す実施例では上記ヒンジ(14)と蓋体(15)の中心部を一辺とする断面略三角形状に形成されている。また、該押圧リブ(17)は中実形状に形成してもよいが、図に示すように中空形状に形成して適宜の弾性を有する弾性片とすると、上記蓋体(15)を傾斜開口縁(13)に弾性的に密着させることができ、一層効果的である。
【0014】
上記キャップ(2)の側面には、上記エアタイトスリーブ(9)が前進位置に移動するとき、上記押圧リブ(17)が嵌入するよう窓孔(18)を設けてある。これにより、上記筆記先端(3)に当って上記蓋体(15)が押圧されたとき、該押圧リブ(17)が該窓孔(18)内に退避し、該蓋体(15)は回動が許容され、開放される。
【0015】
上記筆記体(1)は、上記首部(10)と太径部(5)の間に中間部(19)を有し、該中間部(19)がキャップ(2)に設けた保持片(20)により弾性的に保持されている。すなわち、図3に示すように、該保持片(20)はスリット(21)…を有する略円錐形に形成され、上記首部(10)を大口径側から押し込んで該保持片(20)の小口径側へ貫通させれば、該筆記体から脱落しないようにキャップを取り付けることができる。なお、保持片(20)はキャップ(2)と一体的に成形してあるが、別体に成形した後、固着するようにしてもよい。
【0016】
図3に示すように、図示の実施例では、上記キャップ(2)は、上記エアタイトスリーブ(9)の他、上記通孔(4)及び窓孔(18)を形成した先具(22)及び該先具(22)に連結されるキャップ本体(23)の3つの部品で構成されている。上記先具(22)は、内方に上記エアタイトスリーブ(9)が装着され、内面に該エアタイトスリーブ(9)の側面を案内するガイド面(24)を有し、外面にはエアタイトスリーブに形成した突起(25)が嵌入する案内溝(26) が形成され、またエアタイトスリーブ(9)の後部に形成したフランジ状のストッパー(27)が当接する端面(28)を後端に有する。また、該先具(22)の周面には、上記キャップ本体(23)に装着した際、該キャップ本体(23)に形成した抜止突起(29)が嵌合する抜け止め用の係合溝(30)及びキャップ本体(23)に形成した回り止め突起(31)が嵌合する回り止め用の長溝(32)が設けられている。
【0017】
上記キャップ本体(23)は、使用の際に実質的なグリップとなるので、2色成形やインジェクション成形等の要領で基部を硬質層に形成し表面部を軟質層に形成した多層構造にすることもできる(図示略)。該キャップ本体(23)の外方にはクリップ(33)を設けてあり、内方には上記保持片(20)及び抜止突起(29)等が形成されている。
【0018】
而して、図1に示す収納位置において、キャップ(2)は筆記体(1)のロック部(6)に係合部(7)が係合して収納位置に保持されている。また、筆記先端(3)は、エアタイトスリーブ(9)内に収納され、首部(10)に嵌合部(11)が嵌合すると共に蓋体(15)が押圧リブ(17)によって傾斜開口縁(13)に圧着されているので、該エアタイトスリーブ(9)内が気密状態に保持され、該筆記先端の乾燥が防止されている。
【0019】
図1に示す状態から、上記キャップ(2)を筆記位置に向けて移動(図1において右行)させると、上記ロック部(6)と係合部(7)の係合が外れるが、上記エアタイトスリーブ(9)は嵌合部(11)が首部(10)に嵌合しているので、筆記体に保持された状態で後退位置から前進位置に向けて移動する(図5)。
【0020】
上記前進位置で該エアタイトスリーブ(9)はストッパー(27)が先具(22)の端面(28)に当って移動が阻止され、この状態で上記押圧リブ(17)は窓孔(18)に対向しているから、該窓孔(18)に嵌入可能である。したがって、更にキャップ(2)を移動させることにより上記筆記先端(3)が蓋体(15)に当り、該蓋体(15)は回動して開放され、筆記先端(3)はキャップの通孔(4)から突出し、筆記位置に到達する(図6)。このとき、上記筆記体(1)のロック部(6)にキャップ(2)の係合部(8)が係合するので、該キャップは筆記位置に保持され、キャップ本体(23)を握って筆記することができる。このときのロック部(6)との係合力は、筆圧に耐える程度に設定してある。
【0021】
図6に示す筆記位置から収納位置に向けてキャップ(2)を移動(図6において左行)させると、筆圧以上の力により上記ロック部(6)と係合部(8)の係合が外れ、途中で筆記体(1)の上記首部(10)とエアタイトスリーブ(9)の嵌合部(11)が嵌合する(図7)から、該エアタイトスリーブ(9)はキャップの移動に伴って後退位置へ向けて移動する。その結果、上記押圧リブ(17)は窓孔(18)から出てキャップ(2)の内面(16)に摺接し、上記蓋体(15)を上記傾斜開口縁(13)に向けて押し付け、図1に示す収納位置に到達して上記キャップ(2)は収納位置に保持される。
【0022】
【発明の効果】
本発明は、上記のように構成されているので、筆記体の先部に嵌着したキャップを収納位置から筆記位置へ移動するだけでエアタイトスリーブの蓋体が開放して筆記先端をキャップの通孔から突出させて筆記することができ、また、上記キャップを筆記位置から収納位置へ移動すると、上記蓋体は押圧リブにより回動してエアタイトスリーブの開口部を閉塞し、上記筆記先端の周囲を気密的に取り囲んで該筆記先端の乾燥を防止することができ、ひとつの動作で筆記体の出没、気密保持が可能である。
【0023】
また、上記蓋体を押圧リブにより傾斜開口縁に圧着するようにしたので、蓋体全体に圧着力を伝えることができ、該蓋体は確実に開口縁に密着され、その上、開口縁を傾斜させているから、該蓋体の回動量は、開口縁を直角に設けた場合に比べて少なくでき、したがって、ヒンジにかかるストレスが少なく、耐久性を向上させることができる。また、上記蓋体を圧着するために、特別のスプリング等を使用していないから、構成が簡単であり、上記押圧リブにより常時圧着力を付与させることができ、部品点数が少なく、全体を細径化することが可能であり、組立が簡単で経済的に得ることができる。

DETAILED DESCRIPTION OF THE INVENTION
With reference to FIG. 1, FIG. 2, the cap (2) is attached to the front part of the cursive body (refill) (1) so that the movement to an axial direction is possible. The cap (2) is made of a plastic material, and a storage position (FIG. 1) in which the writing tip (3) of the writing body (1) is stored inward and a writing tip (3) are formed at the tip of the cap. It moves between the writing positions (FIG. 6 described later) protruding from the through-hole (4). In the embodiment shown in the figure, the cap (2) is slidable in the axial direction of the cursive body (1), but the cap is screw-engaged with the cursive body and is moved axially by spiral movement. It may be movable (not shown).
[0009]
A lock portion (6) is formed on the outer periphery of the large-diameter portion (5) of the cursive body (1), and the lock portion (6) is written in the cap (2) correspondingly. Engaging portions (7) and (8) are provided to engage at the position and the storage position, respectively. The cap (2) is held in the storage position by the engagement portion (7) engaging the lock portion (6), and the engagement portion (8) is engaged by the lock portion (6). Hold in writing position.
[0010]
As shown in FIG. 4, an air tight sleeve (9) having an outer surface of a substantially rectangular tube shape and an inner surface of a substantially cylindrical shape is inserted into the cap (2) so as to surround the writing tip (3). The air tight sleeve (9) is movable back and forth within a predetermined range, that is, between the forward position and the backward position.
[0011]
At the rear part of the air tight sleeve (9), there is provided a fitting part (11) that fits air tightly to the neck part (10) of the writing body (1). The fitting between the fitting portion (11) and the neck portion (10) is such that when the air tight sleeve (9) is stopped at the advanced position, the air tight sleeve (9) and the writing body (1) are relatively pivoted. It is detachably fitted to such an extent that it can be removed when moved in a direction approaching the direction.
[0012]
An opening (12) is formed in the front portion of the air tight sleeve (9) so that the writing tip (3) of the writing body (1) can be inserted, and the front surface of the opening (12) is a shaft. The inclined opening edge (13) is inclined at an angle of about 60 ° or less, preferably about 45 ° with respect to the core. A lid (15) is connected to the inner end of the opening (12) via a hinge (14) so as to be opened and closed. As shown in FIG. 4, the hinge (14) extends in the width direction of the lid (15), and causes the lid (15) to closely contact the inclined opening edge (13).
[0013]
When the air tight sleeve (9) moves to the retracted position on the back surface of the lid (15), the lid (15) is rotated against the inner surface (16) of the cap (2), A pressing rib (17) is provided so as to be crimped to the inclined opening edge (13). The pressing rib (17) may be formed in an appropriate shape. However, in the embodiment shown in the figure, the pressing rib (17) is formed in a substantially triangular cross section with the central portion of the hinge (14) and the lid (15) as one side. Yes. The pressing rib (17) may be formed in a solid shape. However, if the pressing rib (17) is formed in a hollow shape as shown in the drawing to be an elastic piece having appropriate elasticity, the lid (15) is inclined and opened. It can be elastically adhered to the edge (13) and is more effective.
[0014]
A window hole (18) is provided on a side surface of the cap (2) so that the pressing rib (17) is fitted when the air tight sleeve (9) moves to the forward position. Accordingly, when the lid (15) is pressed against the writing tip (3), the pressing rib (17) is retracted into the window hole (18), and the lid (15) is rotated. Movement is allowed and released.
[0015]
The cursive body (1) has an intermediate part (19) between the neck part (10) and the large diameter part (5), and the intermediate part (19) is a holding piece (20) provided on the cap (2). ) Is held elastically. That is, as shown in FIG. 3, the holding piece (20) is formed in a substantially conical shape having slits (21), and the neck (10) is pushed in from the large diameter side to reduce the holding piece (20). If it penetrates to the caliber side, a cap can be attached so as not to drop off from the cursive body. The holding piece (20) is formed integrally with the cap (2), but may be fixed after being formed separately.
[0016]
As shown in FIG. 3, in the illustrated embodiment, the cap (2) includes, in addition to the air tight sleeve (9), a tip (22) formed with the through hole (4) and a window hole (18), and It consists of three parts of a cap body (23) connected to the tip (22). The tip (22) is provided with the air tight sleeve (9) on the inner side, has a guide surface (24) for guiding the side surface of the air tight sleeve (9) on the inner surface, and is formed on the outer surface as an air tight sleeve. A guide groove (26) into which the projection (25) is inserted is formed, and an end face (28) with which a flange-like stopper (27) formed at the rear part of the air tight sleeve (9) abuts is provided at the rear end. In addition, a retaining groove for retaining the retaining member (29) formed on the cap body (23) is fitted to the peripheral surface of the tip (22) when the cap body (23) is mounted. (30) and an anti-rotation long groove (32) into which an anti-rotation protrusion (31) formed on the cap body (23) is fitted.
[0017]
Since the cap body (23) becomes a substantial grip when in use, a multi-layer structure in which the base portion is formed in a hard layer and the surface portion is formed in a soft layer in a manner such as two-color molding or injection molding. (Not shown). A clip (33) is provided on the outer side of the cap body (23), and the holding piece (20) and the retaining protrusion (29) are formed on the inner side.
[0018]
Thus, in the storage position shown in FIG. 1, the cap (2) is held in the storage position with the engagement portion (7) engaged with the lock portion (6) of the writing body (1). The writing tip (3) is housed in the air tight sleeve (9), the fitting portion (11) is fitted to the neck portion (10), and the lid (15) is inclined by the pressing rib (17). Since it is pressure-bonded to (13), the inside of the air tight sleeve (9) is held in an airtight state, and drying of the writing tip is prevented.
[0019]
When the cap (2) is moved toward the writing position from the state shown in FIG. 1 (right line in FIG. 1), the locking portion (6) and the engaging portion (7) are disengaged. Since the fitting portion (11) is fitted to the neck portion (10), the air tight sleeve (9) moves from the retracted position to the advanced position while being held by the writing body (FIG. 5).
[0020]
In the forward position, the air tight sleeve (9) is prevented from moving when the stopper (27) hits the end face (28) of the tip (22), and in this state, the pressing rib (17) is brought into contact with the window hole (18). Since they face each other, they can be fitted into the window holes (18). Therefore, by further moving the cap (2), the writing tip (3) hits the lid (15), the lid (15) is rotated and opened, and the writing tip (3) passes through the cap. It protrudes from the hole (4) and reaches the writing position (FIG. 6). At this time, since the engaging portion (8) of the cap (2) is engaged with the lock portion (6) of the writing body (1), the cap is held at the writing position and holds the cap body (23). Can write. At this time, the engaging force with the lock portion (6) is set to withstand the pen pressure.
[0021]
When the cap (2) is moved from the writing position shown in FIG. 6 toward the storage position (left line in FIG. 6), the locking portion (6) and the engaging portion (8) are engaged by a force greater than the writing pressure. And the neck part (10) of the cursive body (1) and the fitting part (11) of the air tight sleeve (9) are fitted together (FIG. 7), so that the air tight sleeve (9) moves the cap. Along with this, it moves toward the retracted position. As a result, the pressing rib (17) comes out of the window hole (18) and slidably contacts the inner surface (16) of the cap (2), pressing the lid (15) toward the inclined opening edge (13), When the storage position shown in FIG. 1 is reached, the cap (2) is held in the storage position.
[0022]
【The invention's effect】
Since the present invention is configured as described above, simply moving the cap fitted to the tip of the writing body from the storage position to the writing position opens the lid of the air tight sleeve so that the writing tip passes through the cap. When the cap is moved from the writing position to the storage position, the lid is rotated by the pressing rib to close the opening of the air tight sleeve, and the periphery of the writing tip The writing tip can be prevented from drying, and the writing body can be moved in and out and kept airtight in one operation.
[0023]
Further, since the lid body is crimped to the inclined opening edge by the pressing rib, the crimping force can be transmitted to the entire lid body, and the lid body is securely adhered to the opening edge, and the opening edge is Since it is inclined, the amount of rotation of the lid can be reduced as compared with the case where the opening edge is provided at a right angle, so that the stress applied to the hinge is small and the durability can be improved. In addition, since no special spring or the like is used for crimping the lid body, the configuration is simple, the crimping force can be constantly applied by the pressing rib, the number of parts is small, and the whole is thin. The diameter can be increased, and the assembly is simple and economical.
