Description

本発明は、マーキングペン等の出没式塗布具に関する。ペン先部材の封止構造を備えた出没式塗布具に関する。 The present invention relates to a retractable applicator such as a marking pen. The present invention relates to a retractable applicator provided with a sealing structure for a nib member.

塗布具の一つにマーキングペンと称されるものがある。マーキングペンは、樹脂や繊維束等で作られたペン先チップを有する筆記用具の一種であり、当該ペン先チップからインキを漏出させて文字や絵を書いたり、ラインを引いたりといった用途に供するものである。 One applicator is called a marking pen. A marking pen is a type of writing instrument that has a nib tip made of resin, fiber bundles, etc., and is used for applications such as writing letters and pictures by drawing ink from the nib tip and drawing lines. Is.

ところで、マーキングペンは、通常、ペン先チップの乾燥を防ぐためにキャップを取り付けて、封止されるものが多い。このようなマーキングペンは、使用時には、キャップを取り外してペン先チップを塗布し、不使用時には、キャップを取り付けてペン先チップを封止するものである。しかしながら、このようなマーキングペンのようにキャップを設けると、使用時にキャップが不要となるため、紛失するおそれがある。 Incidentally, many marking pens are usually sealed with a cap attached to prevent the tip of the pen tip from drying. When such a marking pen is used, the cap is removed and the nib tip is applied, and when not in use, the cap is attached to seal the nib tip. However, if a cap is provided as in such a marking pen, the cap becomes unnecessary during use, and thus it may be lost.

そこで、近年では、ノック式のマーキングペンが開発されている。このノック式のマーキングペンとしては、例えば、特許文献１に記載の筆記具がある。
特許文献１に記載の筆記具は、内外を連通する連通孔を設け、この連通孔を板バネによって開閉することによって、筆記芯を外気からシールし、インキの乾燥を防止している。この特許文献１に記載の筆記具であれば、自己の動作によってシールされるので、キャップが不要となる。そのため、この特許文献１に記載の筆記具であれば、キャップの紛失が生じることを防止できる。 In recent years, therefore, knock type marking pens have been developed. As this knock type marking pen, for example, there is a writing instrument described in Patent Document 1.
The writing instrument described in Patent Document 1 is provided with a communication hole that communicates the inside and the outside, and the communication hole is opened and closed by a leaf spring to seal the writing core from the outside air and prevent ink from drying. If it is the writing instrument of this patent document 1, since it seals by an own operation | movement, a cap becomes unnecessary. Therefore, if it is a writing instrument of this patent document 1, it can prevent that the loss of a cap arises.

しかしながら、特許文献１に記載の筆記具は、板バネの弾性復元力によって連通孔の壁面を圧着して閉塞するので、挟持部分の距離が近くなると、圧着力が弱くなる。そのため、十分に気密性を確保するためには、１ｋｇ程度のバネ圧を確保する必要があった。
また、特許文献１に記載の筆記具は、板バネの弾性復元力によって壁面間を圧着して閉塞するので、板バネの押圧部分間の距離が大きくなるにつれて反力が大きくなる。すなわち、筆記部が前方に進み、板バネの押圧部分間が離れるにつれて、その板バネから受ける力も強くなり、重くなってしまう。その結果、筆記部を軸筒から突出させるために姿勢変更を行うにあたって、かなりの力が必要となってしまう。そのため、特許文献１に記載の筆記具は、過剰に力を加える必要があり、スムーズに筆記部を露出させることができないという問題がある。
さらに、特許文献１に記載の筆記具は、板バネによって連通孔を圧着させて密閉するので、開閉を繰り返すことによって板バネが徐々に弱まり、封止機能が弱くなる場合があった。 However, the writing instrument described in Patent Literature 1 closes the wall surface of the communication hole by crimping with the elastic restoring force of the leaf spring, so that the crimping force is weakened when the distance between the sandwiched portions is reduced. Therefore, in order to ensure sufficient airtightness, it is necessary to secure a spring pressure of about 1 kg.
Moreover, since the writing instrument described in Patent Document 1 is closed between the wall surfaces by the elastic restoring force of the leaf spring, the reaction force increases as the distance between the pressed portions of the leaf spring increases. That is, as the writing portion advances forward and the portion between the pressing portions of the leaf springs is separated, the force received from the leaf springs becomes stronger and heavier. As a result, considerable force is required to change the posture in order to cause the writing unit to protrude from the shaft tube. Therefore, the writing instrument described in Patent Document 1 has a problem that it is necessary to apply an excessive force and the writing part cannot be exposed smoothly.
Furthermore, since the writing instrument described in Patent Document 1 is sealed by pressing the communication hole with a leaf spring, the leaf spring is gradually weakened by repeatedly opening and closing, and the sealing function may be weakened.

そこで、本発明は、塗布部の出没が可能であって、塗布部の封止機能が高い出没式塗布具を提供することを課題とする。 Therefore, an object of the present invention is to provide a retractable applicator that allows the applicator part to appear and that has a high sealing function of the applicator part.

上記した課題を解決するための請求項１に記載の発明は、先端に塗布部が露出したペン先部材と、前記ペン先部材を収容する軸筒を備えた出没式塗布具において、前記塗布部を封止する封止空間を形成可能なシール部を有し、前記シール部は、前記塗布部の一部を挿通可能な挿通孔と、磁力を発生可能な磁力発生部を有し、前記塗布部が挿通孔を挿通して封止空間の外部に露出した露出姿勢と、前記塗布部が前記封止空間内に収容された収容姿勢とに切り替え可能であり、前記収容姿勢において、磁力によって挿通孔が閉塞されて封止空間が形成されていることを特徴とする出没式塗布具である。 The invention according to claim 1 for solving the above-mentioned problem is a penetrating applicator provided with a pen tip member having an applicator exposed at a tip and a shaft cylinder that accommodates the pen tip member. A seal portion capable of forming a sealing space for sealing, and the seal portion includes an insertion hole through which a part of the application portion can be inserted and a magnetic force generation portion capable of generating a magnetic force, It is possible to switch between an exposure posture in which the portion is inserted through the insertion hole and exposed to the outside of the sealing space, and a housing posture in which the application unit is accommodated in the sealing space. A retractable applicator characterized in that a hole is closed to form a sealed space.

本発明の構成によれば、塗布部が挿通孔を挿通して封止空間の外部に露出した露出姿勢とすることによって、塗布部の露出部分が封止空間から開放されるので、当該露出部分によって被塗布物に対して、塗布を行うことができる。
また、本発明の構成によれば、収容姿勢における塗布部の封止を磁力発生部で生じる磁力によって行っている。そのため、特許文献１のような板バネによって封止する場合とは異なり、露出姿勢と収容姿勢の切り替え回数に伴って封止機能が低下しない。 According to the configuration of the present invention, the exposed portion of the coating portion is released from the sealing space by the coating portion being exposed to the outside through the insertion hole and exposed to the outside of the sealing space. By this, application can be performed on the object to be applied.
Moreover, according to the structure of this invention, the application part in the accommodation attitude | position is sealed with the magnetic force which arises in a magnetic force generation part. Therefore, unlike the case of sealing with a leaf spring as in Patent Document 1, the sealing function does not deteriorate with the number of times of switching between the exposure posture and the housing posture.

請求項２に記載の発明は、前記挿通孔は、スリットであり、前記シール部は、対向する一対の閉塞壁部を有し、前記閉塞壁部は、前記挿通孔の内壁を構成するものであり、前記磁力発生部は、引き付け合う一対の強磁性体によって構成されており、前記強磁性体は、前記一対の閉塞壁部にそれぞれ設けられており、前記収容姿勢において、一対の閉塞壁部は、前記一対の強磁性体の磁力によって圧着していることを特徴とする請求項１に記載の出没式塗布具である。 According to a second aspect of the present invention, the insertion hole is a slit, the seal portion has a pair of opposed blocking wall portions, and the blocking wall portion constitutes an inner wall of the insertion hole. And the magnetic force generation part is constituted by a pair of attracting ferromagnetic bodies, and the ferromagnetic bodies are respectively provided on the pair of closing wall parts, and in the housing posture, the pair of closing wall parts The crimping applicator according to claim 1, wherein the applicator is pressure-bonded by the magnetic force of the pair of ferromagnetic materials.

本発明の構成によれば、挿通孔がスリットであり、磁力発生部からの磁力が挿通孔の内壁を構成し対向する閉塞壁部同士が近接する方向に働き、閉塞壁部同士が接触して圧着されている。
ここで、磁力は、距離の二乗に反比例するので、距離が近いほど大きな力が働く。すなわち、一対の閉塞壁部が互いに接触した状態では、一対の閉塞壁部が離れた状態に比べて、強磁性体同士の距離が近くなっているので、より強い引力が働く。すなわち、特許文献１のような板バネを使用する場合とは異なり、閉塞壁部が近づいた状態で押圧力が弱くならないので、シール部内がきっちりと密閉され、封止機能が高い。 According to the configuration of the present invention, the insertion hole is a slit, and the magnetic force from the magnetic force generating part works in the direction in which the closed wall parts facing each other constitute the inner wall of the insertion hole, and the closed wall parts are in contact with each other. It is crimped.
Here, since the magnetic force is inversely proportional to the square of the distance, a larger force works as the distance is shorter. That is, in a state where the pair of blocking wall portions are in contact with each other, since the distance between the ferromagnetic bodies is closer than in a state where the pair of blocking wall portions are separated from each other, a stronger attractive force works. That is, unlike the case where a leaf spring as in Patent Document 1 is used, the pressing force does not weaken when the closing wall portion is approaching, so that the inside of the sealing portion is tightly sealed and the sealing function is high.

請求項３に記載の発明は、収容姿勢から露出姿勢に切り替えるときに、前記一方の閉塞壁部にペン先部材の塗布部又は他の部位が当接し、前記一方の閉塞壁部が弾性変形して挿通孔が開口されることを特徴とする請求項２に記載の出没式塗布具である。 According to the third aspect of the present invention, when the housing posture is switched to the exposure posture, the application portion or the other portion of the pen tip member abuts on the one closing wall portion, and the one closing wall portion is elastically deformed. 3. The retractable applicator according to claim 2, wherein the insertion hole is opened.

本発明の構成によれば、収容姿勢においては、一対の閉塞壁部が接触して、強磁性体間の距離が近くなっている。そのため、塗布部が封止空間内で強固に封止される。
ここで、磁力は、距離の二乗に反比例するので、距離が離れると急激に低下する。すなわち、収容姿勢から露出姿勢に切り替える際には、一方の閉塞壁部にペン先部材の塗布部又は他の部位が当接することで、一方の閉塞壁部が弾性変形して挿通孔が開口されて、強磁性体間の距離が離れるので、特許文献１に記載の筆記具のような板バネの弾性復元力によって閉塞する場合に比べて、小さな力で露出姿勢にすることができる。 According to the configuration of the present invention, in the accommodated posture, the pair of blocking wall portions are in contact with each other, and the distance between the ferromagnetic bodies is reduced. Therefore, the application part is firmly sealed in the sealing space.
Here, since the magnetic force is inversely proportional to the square of the distance, it rapidly decreases as the distance increases. That is, when switching from the stowed posture to the exposed posture, the application portion of the pen tip member or another part abuts against one of the closed wall portions, so that one of the closed wall portions is elastically deformed to open the insertion hole. Thus, since the distance between the ferromagnetic bodies is increased, the exposed posture can be set with a small force as compared with the case where the elastic body is closed by the elastic restoring force of a leaf spring such as the writing instrument described in Patent Document 1.

請求項４に記載の発明は、前記塗布部は、塗布時において被塗布物に接触する面であって、所定の方向に延びた塗布面を有し、前記塗布面は、収容姿勢において、前記挿通孔の長手方向と平行となっていることを特徴とする請求項２又は３に記載の出没式塗布具である。 According to a fourth aspect of the present invention, the application unit is a surface that contacts an object to be applied at the time of application, and has an application surface that extends in a predetermined direction. The retractable applicator according to claim 2 or 3, wherein the applicator is parallel to the longitudinal direction of the insertion hole.

本発明の構成によれば、収容姿勢において、塗布部の塗布面が挿通孔と平行となっているので、閉塞壁部との接触等によって、塗布面が痛みにくい。 According to the configuration of the present invention, since the application surface of the application part is parallel to the insertion hole in the accommodated posture, the application surface is unlikely to be painful due to contact with the blocking wall part or the like.

請求項５に記載の発明は、前記磁力発生部は、軸筒の内部に位置していることを特徴とする請求項１〜４のいずれかに記載の出没式塗布具である。 A fifth aspect of the present invention is the retractable applicator according to any one of the first to fourth aspects, wherein the magnetic force generator is located inside the shaft tube.

本発明の構成によれば、磁力発生部が軸筒の内部にあり、軸筒によって隠されているため、見栄えがよい。 According to the configuration of the present invention, since the magnetic force generating part is inside the shaft tube and is hidden by the shaft tube, the appearance is good.

本発明の出没式塗布具によれば、塗布部の出没が可能であって、塗布部の封止機能が高い。 According to the retractable applicator of the present invention, the applicator can protrude and retract, and the sealing function of the applicator is high.

That is, the insertion hole 40 is also a communication hole that communicates the sealing space 47 with the outside.
Specifically, the insertion hole 40 is a slit, and its extending direction (longitudinal direction) is in the same direction as the extending direction of the application surface 28 of the pen tip member 6 and is parallel to each other.
Moreover, the length of the insertion hole 40 is larger than the application part 10 of the nib member 6, and the application part 10 can be inserted in a state opened in a direction orthogonal to the extending direction.

本体部３９を別の観点からみると、本体部３９は、挿通孔４０の内壁を構成する一対の閉塞壁部４２，４３と、閉塞壁部４２，４３と固定部３８を接続する接続壁部４５，４６から構成されている。

続いて、退避状態（収容姿勢）における出没式塗布具１の各部材の位置関係について説明する。 Then, the positional relationship of each member of the retractable applicator 1 in the retracted state (accommodating posture) will be described.

出没式塗布具１は、図２（ｂ）に示されるように、軸筒２の内部に主要部材が収納されている。軸筒２の後端部を構成する後端側開口部１２には、ノック筒３が挿入されており、フランジ部１５は、軸筒２の突出部１８と係合している。ノック筒３の前方側にインキ収容部５が位置しており、支持部２１の外周をばね部材８が囲んでいる。
ばね部材８は、シール部７の固定部３８と一体となっており、インキ収容部５の先端面との間に位置している。
固定部３８の軸方向Ｌの先端面は、係止部１９の後端面と当接しており、係止部１９によって前方側への移動が規制されている。 As shown in FIG. 2 (b), the retractable applicator 1 has a main member housed in the shaft tube 2. The knock cylinder 3 is inserted into the rear end side opening portion 12 constituting the rear end portion of the shaft cylinder 2, and the flange portion 15 is engaged with the protruding portion 18 of the shaft cylinder 2. The ink storage portion 5 is located on the front side of the knock cylinder 3, and the spring member 8 surrounds the outer periphery of the support portion 21.
The spring member 8 is integrated with the fixing portion 38 of the seal portion 7 and is positioned between the front end surface of the ink containing portion 5.
The front end surface of the fixing portion 38 in the axial direction L is in contact with the rear end surface of the locking portion 19, and movement toward the front side is restricted by the locking portion 19.

また、ペン先部材６の付近では、支持部２１の連通孔２４に、ペン先部材６が挿着されており、支持部２１がペン先部材６の取付部２６を保持している。
すなわち、出没式塗布具１は、支持部２１の軸方向Ｌの前方側において、支持部２１からペン先部材６の塗布部１０が露出しており、支持部２１の軸方向Ｌの後方側において、支持部２１からペン先部材６の吸引部２７が収容本体２０の収容空間２３の内部に位置している。また、吸引部２７は、収容本体２０内部でインキ吸蔵体２２と接触している。
つまり、出没式塗布具１は、塗布部１０に圧力が加わると、インキ吸蔵体２２で保持されたインキが吸引部２７で吸引され、取付部２６を経由して塗布部１０に伝わる状態となっている。 Further, in the vicinity of the pen tip member 6, the pen tip member 6 is inserted into the communication hole 24 of the support portion 21, and the support portion 21 holds the attachment portion 26 of the pen tip member 6.
That is, in the retractable applicator 1, the application part 10 of the pen tip member 6 is exposed from the support part 21 on the front side in the axial direction L of the support part 21, and on the rear side in the axial direction L of the support part 21. The suction part 27 of the pen point member 6 from the support part 21 is located inside the accommodation space 23 of the accommodation body 20. The suction unit 27 is in contact with the ink storage body 22 inside the housing body 20.
That is, when the pressure is applied to the application unit 10, the retractable applicator 1 is in a state where the ink held by the ink occlusion body 22 is sucked by the suction unit 27 and transmitted to the application unit 10 via the attachment unit 26. ing.

また塗布部１０付近に注目すると、出没式塗布具１は、塗布部１０が封止空間４７内に収容された収容姿勢となっている。 Further, when paying attention to the vicinity of the application part 10, the retractable applicator 1 is in an accommodation posture in which the application part 10 is accommodated in the sealed space 47.

シール部７の挿通開口４１には、支持部２１が圧入されており、挿通開口４１は、支持部２１及びペン先部材６の取付部２６によって閉塞されている。
また先端側開口部１１の軸方向Ｌの投影面上に挿通孔４０が位置している。軸方向Ｌからみたときに先端側開口部１１の中心は、挿通孔４０の中心と一致している。 The support portion 21 is press-fitted into the insertion opening 41 of the seal portion 7, and the insertion opening 41 is closed by the support portion 21 and the attachment portion 26 of the pen tip member 6.
Further, the insertion hole 40 is positioned on the projection surface in the axial direction L of the distal end side opening 11. When viewed from the axial direction L, the center of the distal opening 11 coincides with the center of the insertion hole 40.

強磁性体３６，３７は、閉塞壁部４２，４３の外側面に設けられている。すなわち、強磁性体３６，３７は、閉塞壁部４２，４３を挟んで、対向する位置関係となっている。
強磁性体３６と強磁性体３７は、磁力によって互いに引かれ合っており、シール本体３５の閉塞壁部４２，４３同士を挟持している。すなわち、挿通孔４０は、その内側面たる閉塞壁部４２，４３同士が磁力によって圧着されることによって、閉塞されている。言い換えると、閉塞壁部４２は、径方向において、引力によって閉塞壁部４３と重なっている。このように、シール部７は、挿通孔４０及び挿通開口４１が閉塞されており、封止空間４７が密閉空間となっている。 The ferromagnetic bodies 36 and 37 are provided on the outer surfaces of the blocking wall portions 42 and 43. That is, the ferromagnetic bodies 36 and 37 are in a positional relationship facing each other with the blocking wall portions 42 and 43 interposed therebetween.
The ferromagnetic body 36 and the ferromagnetic body 37 are attracted to each other by magnetic force, and sandwich the blocking wall portions 42 and 43 of the seal body 35. In other words, the insertion hole 40 is closed by pressure-bonding the blocking wall portions 42 and 43 that are the inner side surfaces thereof with a magnetic force. In other words, the blocking wall portion 42 overlaps the blocking wall portion 43 by attractive force in the radial direction. As described above, in the seal portion 7, the insertion hole 40 and the insertion opening 41 are closed, and the sealing space 47 is a sealed space.

続いて、退避状態（収容姿勢）から塗布可能状態（露出姿勢）に変更する際の動作及び各部材の位置関係について説明する。 Next, the operation when changing from the retracted state (accommodating posture) to the applicationable state (exposed posture) and the positional relationship of each member will be described.

使用者が指等によってノック筒３を押圧し、その後ノック筒３を離すと、出没式塗布具１は、ペン先部材６の塗布部１０が挿通孔４０から露出して、退避状態から塗布可能状態に変更される。 When the user presses the knock cylinder 3 with a finger or the like and then releases the knock cylinder 3, the retractable applicator 1 can be applied from the retracted state with the application portion 10 of the nib member 6 exposed from the insertion hole 40. Changed to state.

このとき、出没式塗布具１では、図５（ａ），図５（ｂ）のように、使用者によるノック筒３への押圧力によって、ばね部材８による後方側への付勢力に反して、インキ収容部５及びペン先部材６が一体的に前方側に移動する。その結果、インキ収容部５の支持部２１の先端部及び／又はペン先部材６の塗布部１０がシール部７のシール本体３５の閉塞壁部４２，４３と接触し、押圧力が閉塞壁部４２，４３に伝わる。
そうすると、閉塞壁部４２，４３の少なくとも一方（本実施形態では閉塞壁部４２，４３の双方）が広がる方向に弾性変形して、挿通孔４０の一部に隙間ができ、当該隙間に塗布部１０の一部が進入していく。
そして、インキ収容部５及びペン先部材６の前方側への移動に伴い、隙間が拡張していき、それに伴い強磁性体３６，３７間の距離も離れていくので、強磁性体３６，３７の閉塞壁部４２，４３への押圧力も弱くなる。その後、図５（ｂ），図５（ｃ）のように、隙間の径方向の距離（閉塞壁部４２，４３の距離）が一定の距離まで開くと、強磁性体３６，３７の閉塞壁部４２，４３への押圧力がほとんどなくなり、挿通孔４０が開口し、塗布部１０が挿通孔４０を挿通する。すなわち、出没式塗布具１は、塗布部１０が挿通孔４０を挿通して封止空間４７の外部に露出した露出姿勢となる。
そして、使用者が指を離し、使用者からの押圧力がなくなると、インキ収容部５及びペン先部材６が若干後方側への移動し、軸筒２と収容本体２０間での係合により、軸筒２の先端側開口部１１から塗布部１０が露出した状態で保持される。 At this time, in the retractable applicator 1, as shown in FIGS. 5 (a) and 5 (b), the pressing force applied to the knock cylinder 3 by the user against the urging force of the spring member 8 toward the rear side. The ink container 5 and the nib member 6 are integrally moved forward. As a result, the tip end portion of the support portion 21 of the ink containing portion 5 and / or the application portion 10 of the pen tip member 6 come into contact with the blocking wall portions 42 and 43 of the seal body 35 of the seal portion 7, and the pressing force is applied to the blocking wall portion. 42, 43.
Then, at least one of the blocking wall portions 42 and 43 (both of the blocking wall portions 42 and 43 in this embodiment) is elastically deformed in a direction in which a gap is formed in a part of the insertion hole 40, and the application portion is formed in the gap. Part of 10 enters.
As the ink container 5 and the nib member 6 move forward, the gap expands and the distance between the ferromagnetic bodies 36 and 37 increases accordingly. The pressing force to the closed wall portions 42 and 43 is also weakened. After that, as shown in FIGS. 5B and 5C, when the radial distance of the gap (distance between the blocking wall portions 42 and 43) opens to a certain distance, the blocking walls of the ferromagnetic bodies 36 and 37 are opened. The pressing force to the parts 42 and 43 is almost eliminated, the insertion hole 40 is opened, and the application part 10 is inserted through the insertion hole 40. That is, the retractable applicator 1 has an exposed posture in which the applicator 10 is inserted through the insertion hole 40 and exposed to the outside of the sealing space 47.
When the user lifts his / her finger and the pressing force from the user disappears, the ink containing portion 5 and the pen tip member 6 move slightly rearward, and the engagement between the shaft cylinder 2 and the containing main body 20 is caused. The application portion 10 is held in a state where the application portion 10 is exposed from the distal end side opening 11 of the shaft tube 2.

続いて、塗布可能状態（露出姿勢）から退避状態（収容姿勢）に変更する場合について説明する。 Next, a case where the application possible state (exposed posture) is changed to the retracted state (accommodated posture) will be described.

使用者が指等によってノック筒３を再度押圧し、その後ノック筒３を離すと、出没式塗布具１は、ペン先部材６の塗布部１０が挿通孔４０内に退避して、塗布可能状態から退避状態に変更される。 When the user presses the knock cylinder 3 again with a finger or the like and then releases the knock cylinder 3, the applicator portion 10 of the pen tip member 6 is retracted into the insertion hole 40 and can be applied. Is changed to the evacuation state.

このとき、出没式塗布具１では、使用者による押圧を受けて、軸筒２と収容本体２０間での係合が解除されて、インキ収容部５及びペン先部材６が若干前方側へ移動する。
その後、使用者が指を離し、押圧力を受けなくなると、図６（ａ），図６（ｂ）のように、ばね部材８の復元力によってインキ収容部５及びペン先部材６が後方に移動し、挿通孔４０からペン先部材６の塗布部１０が抜け、インキ収容部５の支持部２１の先端部及び／又はペン先部材６の塗布部１０が閉塞壁部４２，４３から離れる。
このとき、ペン先部材６の塗布部１０が挿通孔４０から抜けていくにつれて、弾性復元力により、閉塞壁部４２，４３の撓みが解消されていき、閉塞壁部４２，４３同士が近接する。ある程度近接すると、図６（ｂ），図６（ｃ）のように、強磁性体３６，３７間に働く磁力によってシール本体３５の閉塞壁部４２，４３が互いにさらに近接するように押し付けられて、閉塞壁部４２，４３が圧着し、挿通孔４０が閉塞される。すなわち、出没式塗布具１は、塗布部１０が封止空間４７内に収容された収容姿勢に戻る。 At this time, in the retractable applicator 1, the user presses and the engagement between the shaft tube 2 and the storage body 20 is released, and the ink storage portion 5 and the pen tip member 6 move slightly forward. To do.
Thereafter, when the user releases his / her finger and no longer receives the pressing force, the ink containing portion 5 and the pen tip member 6 are moved backward by the restoring force of the spring member 8 as shown in FIGS. 6 (a) and 6 (b). The application portion 10 of the pen tip member 6 is removed from the insertion hole 40, and the tip end portion of the support portion 21 of the ink containing portion 5 and / or the application portion 10 of the pen tip member 6 is separated from the blocking wall portions 42 and 43.
At this time, as the application part 10 of the nib member 6 comes out of the insertion hole 40, the bending of the blocking wall parts 42 and 43 is eliminated by the elastic restoring force, and the blocking wall parts 42 and 43 come close to each other. . When close to a certain extent, as shown in FIGS. 6B and 6C, the blocking wall portions 42 and 43 of the seal body 35 are pressed closer to each other by the magnetic force acting between the ferromagnetic bodies 36 and 37. The blocking wall portions 42 and 43 are pressure-bonded, and the insertion hole 40 is closed. That is, the retractable applicator 1 returns to the accommodation posture in which the application unit 10 is accommodated in the sealed space 47.

以上のように、本実施形態の出没式塗布具１によれば、強磁性体３６，３７間に働く磁力によって封止する。すなわち、磁力は、強磁性体３６，３７の距離が近づくにつれて強くなっていくので、退避状態にして、閉塞壁部４２，４３を密着させて封止する際には、強磁性体３６，３７間の距離が近くなり、より強い磁力が働く。この強く働く磁力によって、閉塞壁部４２，４３が隙間なく押さえつけられて強固に密着するので、封止機能が高い。すなわち、ペン先部材６の塗布部１０が封止されて、塗布部１０のインキが渇きにくい。 As described above, according to the retractable applicator 1 of the present embodiment, sealing is performed by the magnetic force acting between the ferromagnetic bodies 36 and 37. That is, since the magnetic force increases as the distance between the ferromagnetic bodies 36 and 37 decreases, the ferromagnetic bodies 36 and 37 are sealed when the closed wall portions 42 and 43 are sealed in the retracted state. The distance between them becomes closer, and a stronger magnetic force works. Due to this strong magnetic force, the blocking wall portions 42 and 43 are pressed down without any gaps and are in close contact with each other, so that the sealing function is high. That is, the application part 10 of the nib member 6 is sealed, and the ink of the application part 10 is not easily thirsty.

また、本実施形態の出没式塗布具１によれば、退避状態から塗布可能状態に変更する際には、強磁性体３６，３７間の磁力が働く方向と、インキ収容部５及びペン先部材６の移動方向が交差する方向（直交する方向も含む）となっているので、ばね部材８を圧縮し、閉塞壁部４２，４３を離反できれば、その後に大きな力を必要としない。そのため、容易に退避状態から塗布可能状態に変更することができる。 Further, according to the retractable applicator 1 of the present embodiment, when changing from the retracted state to the coatable state, the direction in which the magnetic force between the ferromagnetic bodies 36 and 37 acts, the ink containing portion 5 and the pen tip member 6 is a direction in which the moving directions of 6 intersect (including directions perpendicular to each other), so that if the spring member 8 can be compressed and the blocking wall portions 42 and 43 can be separated, a large force is not required thereafter. Therefore, it is possible to easily change from the retracted state to the coatable state.

上記した実施形態では、一方の強磁性体３６をＮ型磁石とし、他方の強磁性体３７をＳ型磁石としたが、本発明はこれに限定されるものではなく、一対の強磁性体３６，３７は必ずしも双方が磁石である必要はない。一対の強磁性体３６，３７が磁力によって引き付けられるものであればよい。例えば、一方の強磁性体を磁石とし、他方を一方の強磁性体によって引き付けられる強磁性体（例えば、鉄）としてもよい。 In the embodiment described above, one ferromagnetic body 36 is an N-type magnet and the other ferromagnetic body 37 is an S-type magnet. However, the present invention is not limited to this, and a pair of ferromagnetic bodies 36 is used. , 37 are not necessarily magnets. Any pair of ferromagnetic bodies 36 and 37 may be used as long as they are attracted by magnetic force. For example, one ferromagnetic material may be a magnet, and the other may be a ferromagnetic material (for example, iron) attracted by one ferromagnetic material.

上記した実施形態では、別体であるシール本体３５と強磁性体３６，３７を接着してシール部７を構成したが、本発明はこれに限定されるものではなく、シール本体３５と強磁性体３６，３７が一体物であってもよい。 In the above-described embodiment, the seal body 35 and the ferromagnetic bodies 36 and 37, which are separate bodies, are bonded to form the seal portion 7.

またこの観点からいうと、上記した実施形態のように、閉塞壁部４２，４３の双方を弾性体で形成する必要はなく、閉塞壁部４２，４３のうち一方の閉塞壁部のみを弾性体で形成してもよい。 In the embodiment described above, when changing from the housed posture to the exposed posture, the supporting portion 21 is brought into contact with the closing wall portions 42 and 43 and both the closing wall portions 42 and 43 are elastically deformed, whereby the closing wall portion. Although a gap is formed between 42 and 43, the present invention is not limited to this, and the supporting portion 21 is brought into contact with one closing wall portion 42 and only one closing wall portion 42 is elastically deformed. Thus, a gap may be formed between the blocking wall portions 42 and 43.
From this point of view, it is not necessary to form both of the blocking wall portions 42 and 43 with an elastic body as in the above-described embodiment, and only one of the blocking wall portions 42 and 43 is an elastic body. May be formed.

具体的には、図８に示されるように、先端側形成部５０の内側面は、その軸方向の中間部から先端側の先端側開口部１１に向けて、テーパー状となっている。すなわち、先端側形成部５０は、軸方向の後方側から前方側に向けて、傾斜した傾斜面５１を備えており、その内径が漸次小さくなっている。そして、組み立てた状態において、シール部７の固定部３８は、先端側の先端側開口部１１に向かって圧入されており、傾斜面５１と密着して弾性変形している。 In the above-described embodiment, the forward movement of the seal portion 7 is restricted by providing the rib-like locking portion 19, but the present invention is not limited to this, and the distal end side of the shaft tube 2. An inclined surface 51 may be provided in a part of the forming portion 11 and the forward movement of the seal portion 7 may be locked by the inclined surface 51.
Specifically, as shown in FIG. 8, the inner side surface of the distal end side forming portion 50 is tapered from the axial intermediate portion toward the distal end side opening portion 11 on the distal end side. That is, the front end side forming portion 50 includes an inclined surface 51 that is inclined from the rear side in the axial direction toward the front side, and the inner diameter thereof gradually decreases. In the assembled state, the fixing portion 38 of the seal portion 7 is press-fitted toward the distal end side opening 11 on the distal end side, and is in close contact with the inclined surface 51 and elastically deformed.
