Description

明 細 書 歯ブラシ 技術分野  Description Toothbrush Technical field
本発明は、 歯間進入性、 歯垢除去機能、 外観差別性に優れるとともに、 毛立ち も良好な平線植毛式の歯ブラシに関する。 背景技術  TECHNICAL FIELD The present invention relates to a flat-line flocked toothbrush which is excellent in interdental penetration, plaque removing function, and appearance discrimination, and has good hairiness. Background art
平線植毛式の歯ブラシは、 平線と呼ばれる金属片またはプラスチック片を用い て毛束を 2つ折りに植毛穴に打ち込むことにより植毛している。 このため、'へヅ ド部植毛面に形成される植毛穴は、 直径 1 . 5〜2 . 2 mmの円形状で隣り合う 植毛穴同士の穴縁間隔を 1 . 0 mm以上とし、 さらに、 植毛する毛束も、 1穴当 たり刷毛本数 1 6 ~ 6 0本 (折り返し本数で 3 2 - 1 2 0本)、 折り返された状 態での 1穴当たりの刷毛断面積の総和が 1 . 0 mm2以上の太い毛束を用いるの が一般的であった。 A flat-line flocking type toothbrush uses a metal piece or a plastic piece called a flat wire to fold the hair bundle into two and drive the hair into the flocking hole. For this reason, the flocked holes formed on the head portion flocked surface are circular with a diameter of 1.5 to 2.2 mm, and the distance between adjacent flocked holes is 1.0 mm or more. The number of bristle bundles to be transplanted is 16 to 60 brushes per hole (32-120 in folded number), and the total brush cross-sectional area per hole in the folded state is 1. It was common to use a thick hair bundle of 0 mm 2 or more.
上記のように太い毛束を用いた場合、 植毛穴数の少数化と毛腰の向上をもたら すため、 生産効率の向上につながるという利点があった。 一方、 太い毛束を用い た場合、 口腔疾患の好発部位である歯頸部、 歯間部、 咬合面の小窩裂溝部などに 刷毛先が届きにくく、 口腔疾患予防上の問題が残されており、 口腔衛生上好まし くない。  The use of a thick bristle bundle as described above has the advantage of reducing the number of flocking holes and improving hair stiffness, leading to an improvement in production efficiency. On the other hand, when a thick hair bundle is used, it is difficult for the brush tip to reach the cervical region, interdental region, pit and fissures on the occlusal surface, which are the most common sites for oral diseases, leaving a problem in preventing oral diseases. And not good for oral hygiene.
すなわち、 このような歯ブラシの場合、 太い毛束による強力な清掃効果を実現 できる一方で、毛束が太いためにブラッシング圧を毛束同士で支え合ってしまい、 毛束を構成する刷毛単体が本来持っているしなやかな動きを発揮することができ ず、 口腔疾患好発部位とされる歯間部、 歯間三角などの小さな隙間部分に毛先が 届きにくくなる。 また、 毛束が太い場合、 歯間進入性が悪いほか、 毛腰が硬くな りがちで、 口腔粘膜に対する刺激も大きい。 さらに、 強度との関係で隣り合う植 毛穴同士の穴縁間隔を 1 . 0 mm以上とする必要があり、 デザイン上の制約も多 くなることから、 新奇性に乏しく、 外観差別性も低かった。 このため、 従来にお いてはヘッド部やハンドルの形状、 色などを工夫することにより、 製品間の差別 化を図っていた。 In other words, in the case of such a toothbrush, while a powerful cleaning effect can be realized by a thick bristle bundle, the brushing pressure is supported by the bristle bundles due to the thick bristle bundles, and the brush itself constituting the bristle bundle is originally used. They cannot exert their supple movements, making it difficult for hair tips to reach small gaps such as the interdental and interdental triangles, which are considered to be sites of oral disease. In addition, when the hair bundle is thick, interdental penetration is poor, and the hair tends to be stiff, and irritation to the oral mucosa is large. In addition, the distance between adjacent flocked holes had to be 1.0 mm or more in relation to strength, and there were many restrictions on the design, resulting in poor novelty and low discrimination in appearance. . For this reason, In addition, the products were differentiated by devising the shapes and colors of the head and handle.
この種の歯ブラシとしては、 例えば、 日本国特閧 2 0 0 0 - 3 0 0 3 4 6号公 報に、 植毛台の幅を 8 mm以内とするとともに、 ハンドル長手方向と平行に毛束 を 4列以上配置し、 さらに外側に位置する毛束を内側に位置する毛束よりも柔ら かくした歯ブラシが示されている。 しかし、 この歯ブラシは、 主としてバス法に よる歯磨き時の口腔内の粘膜に対する安全性の観点から外側の刷毛を柔らかくし たものであり、 本発明とはその技術思想を異にするもので、 植毛穴の穴縁間隔と 植毛される刷毛の断面積との関係については何らの検討もなされていない。  As this type of toothbrush, for example, in Japanese Patent Publication No. 2000-3000-346, the width of the flocking table is set to 8 mm or less, and a bristle bundle is set in parallel with the longitudinal direction of the handle. A toothbrush is shown in which four or more rows are arranged and the outer bristle bundle is softer than the inner bristle bundle. However, this toothbrush softens the outer brush mainly from the viewpoint of safety for the mucous membrane in the mouth when brushing the teeth by the bath method, and differs from the present invention in its technical idea. No investigation has been made on the relationship between the pore edge spacing and the cross-sectional area of the brush to be implanted.
また、 日本国特開平 1 1— 3 1 8 5 6 5号公報には、 長円形状の植毛穴に矩形 状断面のフィラメントを植毛した歯ブラシが示されているが、 植毛穴の穴縁間隔 と植毛される刷毛の断面積との関係については何らの検討もなされていない。 植毛穴の穴縁間隔を狭めて薄壁化した歯ブラシについても、 例えば日本国特開 平 1 1— 1 1 3 6 3 4号公報などに示されているが、 この歯ブラシの場合、 平線 を打ち込む植毛穴の間隔は一定方向において確保されているだけであり、さらに、 植毛穴の穴縁間隔と植毛される刷毛の断面積との関係については何らの検討もな されていない。  Japanese Patent Application Laid-Open No. H11-3185658 discloses a toothbrush in which a filament having a rectangular cross section is implanted in an oval implanted hole. No consideration has been given to the relationship with the cross-sectional area of the brush to be planted. A toothbrush having a thinner wall by narrowing the interval between the flocked holes is also disclosed in, for example, Japanese Patent Application Laid-Open No. H11-1131634. In this toothbrush, a flat line is used. The interval between the implanted flocking holes is only ensured in a certain direction, and further, no study has been made on the relation between the interval between the hole edges of the implanted flocking holes and the cross-sectional area of the brush to be implanted.
また、 日本国特閧 2 0 0 2— 1 0 8 3 4号公報には、 植毛穴たる長孔の向きを 長軸の向きが異なるように選択して組み合わせることにより、 硬さ方向の異なる 毛束を混在配置させた歯ブラシが、 さらに、 日本国特開平 1 0— 3 2 7 9 3 0号 ゃ特開平 1 0— 3 2 7 9 3 1号公報には、 ブラシ基台から多数の毛を突出させ、 多数の毛は少なくとも断面楕円形の毛を複数含むようにした歯ブラシがそれそれ 示されているが、 いずれも植毛穴の穴縁間隔と刷毛の断面積の総和との関係につ いては何らの検討もなされていない。  In addition, Japanese Patent Publication No. 2000-02-100834 discloses that hairs having different hardness directions are selected by combining the directions of the long holes, which are the flocking holes, so that the directions of the long axes are different. Toothbrushes in which bundles are arranged in a mixed manner further increase the number of bristles from the brush base as disclosed in Japanese Patent Application Laid-Open No. H10-302793. Toothbrushes are shown, each of which protrudes and has a large number of bristles including at least a plurality of bristles having an oval cross section. Has not been considered at all.
上述したように、 従来の平線植毛式歯ブラシでは、 植毛のしゃすさから大きめ の植毛穴を採用し、 隣り合う植毛穴の間隔も広めに設定していた。 このため、 使 用する毛束も太くなるとともに、 植毛された毛束同士の間隔も広くなりがちであ つた  As described above, the conventional flat-line flocking type toothbrush employs a large flocking hole because of the bristle of flocking, and the interval between adjacent flocking holes is set to be wide. As a result, the hair bundles used become thicker and the spacing between the planted hair bundles tends to increase.
歯ブラシの必要条件としては、 歯垢除去効果に優れるだけでなく、 口腔内粘膜 に対する安全性が高い点も求められるが、 従来の平線植毛式歯ブラシの場合、 毛 束が太いため、 歯面のスティン除去機能には優れるが、 歯肉などの軟組織に対す る刺激が強く、 特に齒周炎や歯周病の患者に使用させるには細心の注意が必要で あった。 このため、 齒周炎や歯周病の患者などには、 毛腰の柔らかな刷毛を用い た歯ブラシを使用させるのが通例であるが、 毛腰が柔らかいために十分な歯垢除 去機能を発揮できないという問題があった。 The requirements for a toothbrush include not only an excellent plaque removal effect, but also oral mucosa It is also required that the toothbrush has a high level of safety, but in the case of the conventional flat-line flocked toothbrush, the bristles are thick, so it is excellent in removing stin from the tooth surface.However, it strongly stimulates soft tissues such as gums. Great care must be taken to use it in patients with periodontitis and periodontal disease. For this reason, it is customary for patients with periodontitis and periodontal disease to use a toothbrush with a soft bristle brush.However, because the bristle is soft, it has a sufficient plaque removal function. There was a problem that it could not be demonstrated.
本発明は、 上記問題を解決するためになされたもので、 最近接する植毛穴との 間の穴縁間隔と、 植毛穴に植毛される刷毛の断面積の総和とを最適な値に設定す ることにより、 口腔疾患好発部位における歯垢除去機能に優れるとともに、 口腔 内軟組織に対する刺激も柔らかで、 しかも外観差別性、 使用性にも優れた歯ブラ シを提供することを目的とするものである。 発明の開示  The present invention has been made in order to solve the above-mentioned problem, and sets an optimum value for a hole edge interval between a nearest planted hole and a total cross-sectional area of a brush planted in the planted hole. The purpose of the present invention is to provide a toothbrush that is excellent in plaque removal function at a site where oral diseases are likely to occur, has a soft stimulus to soft tissues in the oral cavity, and has excellent appearance discrimination and excellent usability. is there. Disclosure of the invention
上記課題を解決するため、 本発明は、 植毛穴が形成された植毛面を有するへッ ド部と、 それぞれ複数本の刷毛よりなる毛束であって、 前記植毛面の植毛穴にそ れそれ 2つ折りにして平線によつて植毛した複数の毛束とを備えた歯ブラシにお いて、 前記植毛穴の少なくとも一部が、 最近接する任意の植毛穴との間の穴縁間 隔が 1 . 0 mm以下で配設されるとともに、 前記の少なくとも一部の植毛穴に植 毛された各毛束は、 折り返された刷毛部分の断面積の総和が 1穴当たり 1 . 0 m m2以下となるように設定したものである。 In order to solve the above problems, the present invention provides a head portion having a flocked surface with a flocked hole formed therein, and a hair bundle including a plurality of brushes, each of which is provided with a flocked hole on the flocked surface. In a toothbrush having a plurality of hair bundles folded in two and implanted with a flat line, at least a part of the implanted hole has a hole edge interval between any nearest implanted implanted hole. 0 mm or less, and each of the bristle bundles planted in at least a part of the flocking holes has a total cross-sectional area of the folded brush portion of 1.0 mm 2 or less per hole. It is set as follows.
前記刷毛部分の断面積の総和は、 好ましくは植毛穴 1穴当たり 0 . 1 0〜0 . 7 0 mm2の範囲である。 また、 前記の少なくとも一部の植毛穴と最近接する植 毛穴との間の穴縁間隔は、 好ましくは 0 . 2 5〜0 . 7 0 mmの範囲である。 刷毛の断面形状が円形の場合を例に採ると、 折り返された刷毛部分の断面積の 総和が 1 . 0 mm2以下となるのは、 7 m i l (直径 1 7 8 mm) の刷毛で は 1穴当たりおよそ 5〜 1 4本、 すなわち折り返された状態の刷毛部分で 1 0〜 2 8本に相当する。 The total cross-sectional area of the brush portion is preferably in the range of 0.10 to 0.70 mm 2 per flocked hole. In addition, the hole edge distance between at least a part of the flocking holes and the nearest flocking hole is preferably in the range of 0.25 to 0.70 mm. When brush sectional shape is taken as an example the case of a circular, sum 1 of the cross-sectional area of the folded brush portion. 0 mm 2 or less and become the 1 a brush of 7 mil (diameter 1 7 8 mm) Approximately 5 to 14 brushes per hole, ie 10 to 28 brushes in the folded state.
この刷毛本数は、 設計上の歯ブラシ仕様と刷毛径、 断面形状などにより適宜設 定できる。 1つの植毛穴に植毛される刷毛の断面積の総和が 1 . 0 mm2を超え ると、 毛束としての強度が大きくなるため、 剛性の高い毛束となって毛束の柔軟 性が極端に低下し、 好ましくない。 The number of brushes can be appropriately set according to the design toothbrush specifications, brush diameter, cross-sectional shape, and the like. The sum of the cross-sectional areas of the brush to be planted in a single bristle holes exceed 1. 0 mm 2 In such a case, the strength of the hair bundle becomes large, so that the hair bundle becomes highly rigid and the flexibility of the hair bundle extremely decreases, which is not preferable.
さらに、 刷毛の断面積の総和が 1 . 0 mm2以下の毛束を植毛した植毛穴と最 近接する任意の植毛穴との穴縁間隔は 1 . O mm以下が好ましく、 より好ましく は 0 . 2 5〜0 . 7 O mmの範囲である。 穴縁間隔が狭過ぎると、 毛束の間隔も 狭くなり、 歯間に刷毛が入らず、 歯間進入性が低下する。 一方、 穴縁間隔が広が ると、 外観差別性、 使用感が低下する。 植毛穴間隔が 1 . O mmを超えると、 ブ ラッシング運動に伴う毛束の反発作用が強くなり、 毛束のゴッゴヅした感触が加 わり、 使用感が低下するばかりでなく、 毛束の連続した運動が発揮されず、 歯垢 除去効果も低下する。 Furthermore, the hole edge spacing between a flocking hole in which a bristle bundle having a total cross-sectional area of 1.0 mm 2 or less is planted and a nearest flocking hole is preferably 1.0 mm or less, and more preferably 0.1 mm or less. The range is 25-0.7 O mm. If the gap between the holes is too narrow, the spacing between the bristle bundles will also be narrow, and brushes will not enter between the teeth, resulting in reduced interdental penetration. On the other hand, when the distance between the holes is increased, the discriminability of the appearance and the feeling of use are reduced. When the spacing between the flocked holes exceeds 1.0 mm, the repulsion of the hair bundles caused by the brushing movement becomes stronger, and the rugged feel of the hair bundles is added. Exercise is not exhibited, and the plaque removal effect is also reduced.
本発明の歯ブラシは、 細い毛束が最適な間隔で配置されるため、 刷毛の 1本 1 本が歯牙および歯肉に届きやすくなり、 口腔疾患好発部位への毛先の到達性が改 善される。 また、 少数の刷毛本数からなる毛束の植毛により、 従来不可能であつ た細い毛束の連続した動きを発現させることができ、 歯頸部、 歯間乳頭部などの 口腔粘膜に過大な負荷をかけることなく、 歯垢除去、 歯肉マッサージ機能を発現 させることが可能となる。 このように本発明の歯ブラシは、 口腔疾患好発部位に おける歯垢除去機能に優れるとともに、 口腔軟組織に対する安全性が高く、 しか も外観差別性、 使用性にも優れたものである。  In the toothbrush of the present invention, the fine bristle bundles are arranged at optimal intervals, so that each brush can easily reach the teeth and gingiva, and the reach of the bristles to the site where oral diseases are likely to occur is improved. You. In addition, due to the implantation of hair bundles consisting of a small number of brushes, continuous movement of thin hair bundles, which was impossible in the past, can be exhibited, and excessive load on the oral mucosa such as the cervix and interdental papillae It is possible to express the plaque removal and gingival massage functions without applying dentition. As described above, the toothbrush of the present invention is excellent in the plaque removing function at a site where oral diseases are likely to occur, has high safety against oral soft tissues, and is also excellent in appearance discrimination and usability.
上記条件を満たす植毛穴は、へッド部植毛面の任意の位置に形成すればよいが、 少なくともヘッド部植毛面の最外側の一部に配置するのが好ましい。 このように 構成することにより、 ブラッシング時、 刷毛が歯面に接し易くなり、 歯間進入性 をより向上させることができる。 この場合、 刷掃実感やデザイン、 生産性などの 面から、 ヘッド部植毛面の中央付近に太い毛束を配置するようにすれば、 さらに 好ましいものとなる。  The flocking hole that satisfies the above conditions may be formed at an arbitrary position on the head part flocking surface, but is preferably arranged at least on the outermost part of the head part flocking surface. With this configuration, the brush can easily come into contact with the tooth surface during brushing, and the interdental penetration can be further improved. In this case, it is more preferable to arrange a thick hair bundle in the vicinity of the center of the head portion flocked surface in terms of brushing feeling, design, and productivity.
上記植毛穴の穴断面形状は通常用いられている円形や正方形でもよいが、 楕円 形または略楕円形、 長円形または略長円形、 長方形または略長方形など、 穴断面 に短軸方向 (短径または短辺方向) と長軸方向 (長径または長辺方向) を有する 異形の穴形状とするのが好ましい。 この場合、 該植毛穴として、 短軸方向に対す る長軸方向の寸法割合が 1 . 0よりも大きな穴形状の植毛穴を用いるのが望まし レ、。 また、 植毛穴の向きを種々組み合わせて配置を設定することにより、 目的と する毛の当たり心地、 刷掃実感に応じた仕様の設計が可能である。 さらに、 植毛 穴の向きを工夫することにより、 側面からの毛束の見え方を変えることができ、 例えば、 へッド部植毛面の外側に位置して植毛穴の短軸が側縁に沿うように配列 すると、 同じ本数の刷毛を植毛した円形の毛束と比較して細く見え、 外観差別性 も向上させることができる。 また、 隣り合う植毛穴の平線同士の干渉を避けると 同時により密毛化を図るため、 植毛穴の配置を千鳥状としてもよい。 The cross-sectional shape of the above-mentioned flocking hole may be a commonly used circle or square. It is preferable to have a modified hole shape having a short side direction) and a long axis direction (long axis or long side direction). In this case, it is desirable to use, as the flocking hole, a flocking hole having a hole shape whose dimensional ratio in the major axis direction to the minor axis direction is larger than 1.0. Les ,. In addition, by setting the arrangement by variously combining the directions of the flocking holes, it is possible to design the specifications according to the desired feeling of contact with the hair and the feeling of actual brushing. In addition, by changing the direction of the flocking hole, the appearance of the bristle bundle from the side can be changed. By arranging them in such a manner, the brush looks thinner than a circular hair bundle in which the same number of brushes are planted, and the discrimination of appearance can be improved. In addition, the arrangement of the flocking holes may be staggered in order to avoid interference between the flat lines of the adjacent flocking holes and to achieve a denser hair at the same time.
また、 植毛穴に対する平線の打ち込み方向を工夫すれば、 植毛された毛束と植 毛穴との間の隙間を可能な限り小さくすることができ、 毛立ちの優れた植毛部を 作成することができる。すなわち、植毛穴の長軸方向に沿って平線を打ち込めば、 平線に沿って刷毛が並ぶため、 植毛強度が向上する。 また、 平線の打ち込み方向 によりへッド部最外側の毛束が細く見えるため、 外観差別性を向上させることが できる。 この際の植毛穴形状は、 毛束と植毛穴の間隔を狭めるために略長方形が 好ましい。 また、 短軸方向に沿って平線を打ち込む際には、 毛束断面に対する外 接円の直径と植毛穴の短軸方向を合致させることにより、 植毛穴と毛束との空間 をより少なくすることが可能となり、 毛立ちの優れた植毛部を作成することがで きる。 この際、 使用する刷毛断面が円形の場合には、 植毛穴形状を略楕円形、 略 長円形、 略長方形とすればより好ましい。  In addition, if the direction of implantation of the flat wire into the flocking hole is devised, the gap between the flocking and the flocking hole can be made as small as possible, and a flocking portion with excellent hairiness can be created. it can. In other words, if a flat line is driven along the long axis direction of the flocking hole, the brushes are arranged along the flat line, so that the bristling strength is improved. In addition, the hair bundle on the outermost part of the head looks thin depending on the driving direction of the flat wire, so that the appearance discrimination can be improved. In this case, the shape of the flocking hole is preferably substantially rectangular in order to reduce the distance between the bristle bundle and the flocking hole. Also, when driving a flat line along the short axis direction, the diameter of the circumscribed circle with respect to the cross section of the hair bundle and the short axis direction of the hair implantation hole are matched to reduce the space between the hair implantation hole and the hair bundle. This makes it possible to create a flocked portion with excellent hairiness. At this time, when the brush section to be used is circular, it is more preferable that the shape of the flocking hole is substantially elliptical, substantially oblong, or substantially rectangular.
歯ブラシヘッド部は、 形状、 大きさ、 デザインとも、 何ら制限を受けない。 ま た、 歯ブラシで使用する平線の材質は、 真鍮、 ステンレスなどの金属のほか、 硬 質プラスチックや生分解性プラスチックなども使用可能である。 また、 平線の厚 みを調節することによって、 植毛穴と毛束とを確実に固定して空隙を少なくする ことができる。 使用する平線幅には特に制限はなく、 任意に設定できる。  The toothbrush head is not restricted in shape, size or design. The flat wire used for the toothbrush can be made of metal such as brass or stainless steel, or hard plastic or biodegradable plastic. In addition, by adjusting the thickness of the flat wire, it is possible to securely fix the flocking hole and the hair bundle and reduce the gap. The flat line width used is not particularly limited, and can be set arbitrarily.

以下、 本発明の実施の形態について図面を参照して説明する。  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図 1 A〜図 1 Cに本発明に係る歯ブラシの一実施の形態を示す。  1A to 1C show an embodiment of a toothbrush according to the present invention.
図において、 1は複数本の刷毛 2を束ねて構成された毛束であって、 この毛束 1を、 平線 3を用いて 2つ折りにして歯ブラシへヅド部の植毛面 5の植毛穴 4に 打ち込むことにより固定している。 本発明においては、 この毛束 1の植毛に際し て、 最近接する植毛穴 4と 4との間の穴縁間隔 Lを 1 . 0 mm以下とし、 かつ、 これら植毛穴 4 , 4, …に植毛される各毛束 1の刷毛 2の折り返された状態での 1穴当たりの刷毛断面積の総和すなわち折り返された刷毛部分の断面積の総和を 1 . 0 mm2以下となるように設定したものである。 In the figure, reference numeral 1 denotes a bristle bundle formed by bundling a plurality of brushes 2. The bristle bundle 1 is folded into two using a flat wire 3, and a bristle hole 5 in a flocking surface 5 of a toothbrush head portion. It is fixed by driving into 4. In the present invention, at the time of the flocking of the hair bundle 1, the hole edge interval L between the nearest flocking holes 4 and 4 is set to 1.0 mm or less, and the flocking is performed in the flocking holes 4, 4,. The sum of the cross-sectional areas of the brushes per hole in the folded state of the brushes 2 of each bristle bundle 1, that is, the sum of the cross-sectional areas of the turned-up brush portions is set to be 1.0 mm 2 or less. is there.
最近接する植毛穴 4 , 4の穴縁間隔 Lと、 植毛される毛束 1の刷毛 2の断面積 の総和とを上記のような値に設定すると、 刷毛 2の 1本 1本が歯牙および歯肉に 届きやすくなり、 口腔疾患好発部位への毛先の到達性が改善される。 また、 少数 本の刷毛 2からなる毛束 1となるため、 従来不可能であつた細い毛束の連続した 動きを発現させることが可能となり、 歯頸部、 歯間乳頭部などの口腔粘膜に過大 な負荷をかけることなしに優れた歯垢除去、 歯肉マッサージ機能を発揮すること ができる。 By setting the distance L between the closest bristle holes 4 and 4 and the sum of the cross-sectional areas of the brushes 2 of the bristle bundle 1 to be planted to the above values, each brush 2 has one tooth and gingiva. It improves the accessibility of hair tips to sites where oral diseases occur frequently. In addition, since the hair bundle 1 is composed of a small number of brushes 2, it is possible to express the continuous movement of a thin hair bundle, which was impossible in the past, and it is applied to the oral mucosa such as the cervix and interdental papillae. Excessive It can exhibit excellent plaque removal and gingival massage functions without applying a heavy load.
なお、 上記実施の形態では、 植毛穴 4の穴形状を長円形、 刷毛 2の断面形状を 円形とし、 平線 3を長円形状をした植毛穴 4の長手方向と直交する向きに打ち込 んだ場合を示したが、 植毛穴 4の穴形状と刷毛 2の断面形状、 および平線 3の打 ち込み方向はこれに限定されるものではなく、 例えば図 2 A〜図 2 Eに示すよう に歯ブラシの仕様に応じて種々採用できるものである。  In the above-described embodiment, the hole shape of the flocking hole 4 is oval, the cross-sectional shape of the brush 2 is circular, and the flat wire 3 is driven in a direction perpendicular to the longitudinal direction of the flocking hole 4 having an oval shape. However, the hole shape of the flocking hole 4 and the cross-sectional shape of the brush 2 and the driving direction of the flat wire 3 are not limited to these, and for example, as shown in FIGS. 2A to 2E. Various types can be adopted according to the specifications of the toothbrush.
