Description
歯間や歯周ポケットに付着した歯垢を毛丈の長さが異なるブラシ体で確実且つ効率良く除去することができる歯ブラシに関するものである。
It relates to a toothbrush that can reliably and efficiently remove plaque adhering to the interdental and periodontal pockets with brush bodies having different lengths.
従来の歯ブラシは、ブラシ部の先端面が平坦状となっているのが一般的であり、歯の表面や奥歯の噛み合わせ面を磨くためには有効であるが、歯間や歯周ポケットを磨くには不向きである。かかる平坦状のブラシ部を有する歯ブラシで歯間や歯周ポケットを無理に磨いてしまうと、毛先が歯茎に必要以上に当接して歯茎を傷めてしまい、かえって炎症を起こしたり、また、歯のエナメル質が削れてしまって知覚過敏を引き起こしたり、さらには、磨けたつもりでも歯垢が残存していて歯周病の原因となりかねない。
Conventional toothbrushes generally have a flat tip surface, which is effective for brushing the tooth surface and the mating surface of the back teeth. Not suitable for polishing. If a toothbrush having such a flat brush portion forcibly brushes the interdental or periodontal pockets, the hair tips will touch the gums more than necessary and damage the gums. The enamel of the skin may become irritated and cause hypersensitivity, and even if you intend to polish it, plaque may remain and cause periodontal disease.
そこで従来より、歯間や歯周ポケットに付着した歯垢を効果的・効率良く除去することができる歯ブラシの提案が数多くなされており、それらの多くは、ブリッスルや毛先ならびに柄の形状に種々の工夫が施された提供となっている。
Therefore, many toothbrushes that can effectively and efficiently remove plaque adhering to the interdental and periodontal pockets have been proposed, and many of them have various bristle, bristles and handle shapes. It is provided that has been devised.
その実例としては、例えば、歯ブラシの長手方向に沿って配置される中央列の毛丈を中央列の両側列に配置される外側列毛丈よりも高く形成すると共に中央列の先端部分と後端部分も毛丈を中央列の他の部分の毛丈よりも高く形成した「歯ブラシ」（特許文献１）や、ブリッスルの先端（毛先）を連ねたブラシ面が植毛台の短手方向と対向する側面から見た際に下に凸の弧状に湾曲するＵ字形状となっており、植毛台の長手方向と対向する先端側から見た際に中央列部分を頂部とする山状又は上に凸の弧状の形状になっており、かつブリッスルはテーパ形状になっており、植毛台の植毛領域として該植毛領域の面積に対する植毛孔の面積の総和の割合が３５％以上になっている「歯ブラシ」（特許文献２）や、ヘッドの一方の側から近接した間隔を置いて延び出している１組の剛毛を支持しており、それによりそれらの剛毛の各外方端が一緒になって或るブラッシング面を提供し、その際にこのブラッシング面はこのブラッシング面の両端の間でこのブラッシング面の長手方向軸とこのブラッシング面の横断方向軸との両方に沿ってそのプロフィルにおいて凹面状であって或る陥凹面を提供し、その際そのブラッシング面の外側周縁の領域に位置する外側の組の剛毛の自由端はそのブラッシング面について半径方向内向きに指向されている「歯ブラシ」（特許文献３）が提案されている。
As an example, for example, the hair height of the central row arranged along the longitudinal direction of the toothbrush is formed higher than the outer row hair height arranged on both side rows of the central row, and the front end portion and the rear end of the central row “Toothbrush” (patent document 1) in which the hair height is higher than the hair height of the other part of the center row, and the brush surface connecting the bristle tips (tips) faces the short direction of the flocking table When viewed from the side, it has a U-shape that curves downward in a convex arc shape, and when viewed from the tip side facing the longitudinal direction of the flocking table, it has a mountain shape with the central row portion as the top or above The toothbrush has a convex arc shape, and the bristle has a tapered shape, and the ratio of the total area of the flocked hole to the area of the flocked area as a flocked area of the flocking table is 35% or more. (Patent Document 2) or close to one side of the head Supporting a set of bristles extending at intervals, whereby the outer ends of the bristles together provide a brushing surface, wherein the brushing surface is the brushing Providing a certain concave surface in the profile between both ends of the surface along both the longitudinal axis of the brushing surface and the transverse axis of the brushing surface, wherein the outer surface of the brushing surface A “toothbrush” (Patent Document 3) is proposed in which the free ends of the outer bristles located in the peripheral region are oriented radially inward with respect to the brushing surface.
しかしながら、上記における各種「歯ブラシ」の提案は、中央列のブリッスルの毛丈と両側列のブリッスルの毛丈の差が限定されていないことから、短手方向（トゥ側）から見たブリッスルの形状が山伏状の鈍角に形成されることによって、歯間や歯周ポケットに付着した歯垢をブリッスルの先端部で確実且つ効率良く除去することができない、といった問題があった。
However, the proposals of the various “toothbrushes” in the above are not limited in the difference in bristle length between the center row bristles and the bristles on both sides, so the shape of the bristle seen from the short direction (toe side) As a result, there is a problem that the plaque adhering to the interdental or periodontal pocket cannot be removed reliably and efficiently at the tip of the bristle.
本出願人は、以上のような従来から使用されている歯ブラシにおける歯間や歯周ポケットに付着した歯垢を確実且つ効率良く除去することができないといった問題に着目し、その問題点を簡便且つ容易な方法で解決することができないものかという着想の下、歯間や歯周ポケットに付着した歯垢を毛丈の長さが異なるブラシ体で確実且つ効率良く除去することができる歯ブラシを開発し、本発明にかかる「歯ブラシ」の提案に至るものである。

In addition, the toothbrush 10 concerning this invention is not limited to the Example described below, Within the range of the technical idea of this invention, ie, the range of a shape, a dimension, etc. which can exhibit the same effect, It can be changed as appropriate.
図1乃至図５は、本発明にかかる歯ブラシ１０の第一の実施形態を示す説明図であり、図1は短辺方向トゥ側から見た図、図２は短辺方向ヒール側から見た図、図３は長辺方向から見た図、図４は平面図、図５は使用状態説明図である。
1 to 5 are explanatory views showing a first embodiment of a toothbrush 10 according to the present invention, FIG. 1 is a view seen from the short side direction toe side, and FIG. 2 is a view seen from the short side direction heel side. 3 is a view seen from the long side direction, FIG. 4 is a plan view, and FIG.
本実施形態にかかる歯ブラシ１０は、植毛台１１のヒールに把持部１２を備え且つ該植毛台１１に複数のブラシ体が植毛されてブラシ部２０を構成して成る歯ブラシ１０であって、ブラシ部２０のトゥ部ｔ先端に、少なくとも一以上の山形状の突片（トゥ突片）２２が成形されて成り、該突片（トゥ突片）２２の形状に特徴を有する。
The toothbrush 10 according to the present embodiment is a toothbrush 10 that includes a grip portion 12 on a heel of a flocking table 11 and has a plurality of brush bodies planted on the flocking table 11 to form a brush unit 20. At least one or more mountain-shaped projecting pieces (toe projecting pieces) 22 are formed at the tips of the 20 toe parts t, and the shape of the projecting pieces (toe projecting pieces) 22 is characteristic.
すなわち、本実施形態における突片（トゥ突片）２２の形状的第一の特徴は、図１及び図２に示すように、短辺方向Ｍから見て頂点角θ１が鋭角を為し、且つ、両側端方向へ夫々直線的若しくは曲線的な下り傾斜の稜線２１を為して形成されて成る点である。
That is, the first feature of the shape of the projecting piece (toe projecting piece) 22 in the present embodiment is that, as shown in FIGS. 1 and 2, the apex angle θ1 forms an acute angle when viewed from the short side direction M, and These are formed by forming ridgelines 21 that are linearly or curvilinearly downwardly inclined toward the both ends.
該突片（トゥ突片）２２は、ブラシ部２０のトゥ部ｔの先端に少なくとも一以上成形されている。尚、トゥ部ｔとは、図３で示す通り、植毛台１１並びにブラシ部２０の先端部領域を指し、それ以外の基端部領域はヒール部ｈを為す。このとき、トゥ部ｔとヒール部ｈとの長手方向Ｌにおける割合については、特に限定するものではなく、図面では概ね１対１とした場合について示しているが、好みの使い勝手や歯と歯周の状態などの違いに応じて、最適な割合とすることが可能である。
The protruding piece (toe protruding piece) 22 is formed at least one or more at the tip of the toe part t of the brush part 20. As shown in FIG. 3, the toe portion t refers to the distal end region of the flock base 11 and the brush portion 20, and the other proximal end region forms a heel portion h.

It is possible to set the optimal ratio according to the difference in the state of the.
該突片（トゥ突片）２２の成形数に限定はなく、短辺Ｍの寸法によっても成形可能な数は変わるため、本発明の突片（トゥ突片）２２が発揮する作用効果に変わりの無い範囲内で適時決定すれば足りるが、好ましくは一から十の突片（トゥ突片）２２が成形される。少なくとも一の突片（トゥ突片）２２が存在しないと本発明の機能を果たさず、また、十一以上の突片（トゥ突片）２２を成形するとトゥ部ｔ先端の範囲内にあまりに多くの突片（トゥ突片）２２が存在することとなって、通常の歯ブラシ形状とさほど変化ないこととなるためである。このとき、複数の突片（トゥ突片）２２が成形される場合に、夫々の突片（トゥ突片）２２は短辺方向に一列に連続して成形される。
なお、図１（ａ）及び図２（ａ）は一の突片（トゥ突片）２２を成形した場合、図１（ｂ），（ｃ）及び図２（ｂ），（ｃ）は二の突片（トゥ突片）２２を成形した場合について示している。 There is no limitation on the number of moldings of the projecting pieces (toe projecting pieces) 22, and the number that can be formed varies depending on the dimension of the short side M. It is sufficient that the time is determined within a range where there is no gap, but preferably one to ten protruding pieces (toe protruding pieces) 22 are formed. If at least one protruding piece (toe protruding piece) 22 does not exist, the function of the present invention is not achieved, and if more than eleven protruding pieces (toe protruding pieces) 22 are formed, there are too many within the range of the tip of the toe part t. This is because the protruding piece (toe protruding piece) 22 exists and does not change so much from the normal toothbrush shape. At this time, when a plurality of projecting pieces (toe projecting pieces) 22 are formed, each projecting piece (toe projecting piece) 22 is continuously formed in a row in the short side direction.
1 (a) and 2 (a) show a case where one projecting piece (toe projecting piece) 22 is formed, FIGS. 1 (b), (c) and FIGS. 2 (b), 2 (c) show two. This shows a case where the protruding piece (toe protruding piece) 22 is formed.
なお、図１（ａ）及び図２（ａ）は一の突片（トゥ突片）２２を成形した場合、図１（ｂ），（ｃ）及び図２（ｂ），（ｃ）は二の突片（トゥ突片）２２を成形した場合について示している。 There is no limitation on the number of moldings of the projecting pieces (toe projecting pieces) 22, and the number that can be formed varies depending on the dimension of the short side M. It is sufficient that the time is determined within a range where there is no gap, but preferably one to ten protruding pieces (toe protruding pieces) 22 are formed. If at least one protruding piece (toe protruding piece) 22 does not exist, the function of the present invention is not achieved, and if more than eleven protruding pieces (toe protruding pieces) 22 are formed, there are too many within the range of the tip of the toe part t. This is because the protruding piece (toe protruding piece) 22 exists and does not change so much from the normal toothbrush shape. At this time, when a plurality of projecting pieces (toe projecting pieces) 22 are formed, each projecting piece (toe projecting piece) 22 is continuously formed in a row in the short side direction.
1 (a) and 2 (a) show a case where one projecting piece (toe projecting piece) 22 is formed, FIGS. 1 (b), (c) and FIGS. 2 (b), 2 (c) show two. This shows a case where the protruding piece (toe protruding piece) 22 is formed.
該突片（トゥ突片）２２は山形状であって、頂点から両側端方向へ夫々直線的若しくは曲線的な下り傾斜の稜線２１を為して形成される。なお、図１（ａ）及び図２（ａ）は曲線的な稜線２１の場合、図１（ｂ）及び図２（ｂ）は直線的な稜線２１の場合について示している。このとき、傾斜の一方を直線的とし他方を曲線的とする態様も可能である。また、図１（ｃ）及び図２（ｃ）に示すように、下り傾斜の一方を略鉛直状とする態様も可能である。
The projecting piece (toe projecting piece) 22 has a mountain shape, and is formed with a ridge line 21 having a downward or linear downward slope from the apex toward the both ends. FIGS. 1A and 2A show the case of a curved ridge line 21, and FIGS. 1B and 2B show the case of a straight ridge line 21. At this time, an aspect in which one of the slopes is linear and the other is curved is also possible. Moreover, as shown in FIG.1 (c) and FIG.2 (c), the aspect which makes one of the downward inclinations substantially vertical is also possible.
頂点角θ１の角度については，９０度以下の鋭角であれば特に限定はないが、山形状の突片（トゥ突片）２２が歯周ポケット３３に効果的に入り込む形状とすべく、好ましくは１０～６０度の許容角度内で成形される。なお、突片（トゥ突片）２２を複数成形した場合に、各突片（トゥ突片）２２の頂点角θ１について、全てを同角度とするか夫々異なる角度とするかは任意に決定可能である。
The angle of the vertex angle θ1 is not particularly limited as long as it is an acute angle of 90 degrees or less, but preferably the mountain-shaped protruding piece (toe protruding piece) 22 has a shape that effectively enters the periodontal pocket 33. Molded within an allowable angle of 10 to 60 degrees. In addition, when a plurality of projecting pieces (toe projecting pieces) 22 are formed, it is possible to arbitrarily determine whether the apex angles θ1 of the projecting pieces (toe projecting pieces) 22 are all the same angle or different angles. It is.
このように、ブラシ部２０のトゥ部ｔ先端に成形された山形状の突片（トゥ突片）２２が、短辺方向Ｍから見て頂点角θ１が鋭角を為し且つ両側端方向へ夫々直線的若しくは曲線的な下り傾斜の稜線２１を為して形成されることによって、図５（ａ）に示すように、ブラシ体の先端が必要以上に歯茎３１に当接することなく歯周ポケット３３に効果的に入り込み、当該歯周ポケット３３に付着した歯垢を確実且つ効率良く除去することができるため、歯茎３１を傷めることなく歯３０を磨くことが可能であると共に、稜線２１によって成形される傾斜面によって歯３０の表面を効果的に磨くことが可能となる。
As described above, the peak-shaped projecting piece (toe projecting piece) 22 formed at the tip of the toe portion t of the brush portion 20 has an acute vertex angle θ1 when viewed from the short side direction M, and toward the both end directions. By forming the ridgeline 21 with a linear or curved downward slope, the periodontal pocket 33 does not contact the gum 31 more than necessary, as shown in FIG. 5A. It is possible to polish the tooth 30 without damaging the gum 31 and to form the ridge line 21 because the plaque adhering to the periodontal pocket 33 can be surely and efficiently removed. The inclined surface can effectively polish the surface of the tooth 30.
本実施形態における突片（トゥ突片）２２の形状的第二の特徴は、図３に示すように、長辺方向Ｌから見て頂点角θ２が鋭角を為し、且つ、トゥ側辺が略鉛直状の稜線２３を為すと共にヒール側辺がヒール方向へ直線的若しくは曲線的な下り傾斜の稜線２３を為して形成されて成る点である。
As shown in FIG. 3, the second feature of the shape of the projecting piece (toe projecting piece) 22 in the present embodiment is that the vertex angle θ2 forms an acute angle when viewed from the long side direction L, and the toe side is It is a point formed by forming a substantially vertical ridge line 23 and a heel side edge forming a ridge line 23 that is linearly or curved downwardly inclined in the heel direction.
該突片（トゥ突片）２２の成形位置は植毛台１１のトゥ部ｔの先端であって、それ以外のヒール部ｈ側は、長辺方向Ｌから見て略水平状となっている。
The forming position of the projecting piece (toe projecting piece) 22 is the tip of the toe part t of the flocking table 11, and the other heel part h side is substantially horizontal when viewed from the long side direction L.
該突片（トゥ突片）２２は山形状であって、頂点からトゥ側辺は略鉛直状の稜線２３を為し、ヒール側辺はヒール方向へ直線的若しくは曲線的な下り傾斜の稜線２３を為して傾斜して成る。なお、図面では、ヒール側辺の稜線２３を曲線的とした場合について示している。
The projecting piece (toe projecting piece) 22 has a mountain shape, the toe side from the apex forms a substantially vertical ridge line 23, and the heel side has a ridge line 23 that is linearly or curvedly inclined downward in the heel direction. Inclined to make. In the drawing, the ridge line 23 on the heel side is shown as being curved.
頂点角θ２の角度については，９０度以下の鋭角であれば特に限定はないが、山形状の突片（トゥ突片）２２が歯間３２や歯周ポケット３３に効果的に入り込むと共に奥歯３４の最奥にまで確実に届く形状とすべく、好ましくは１０～６０度の許容角度内で成形される。
The angle of the apex angle θ2 is not particularly limited as long as it is an acute angle of 90 degrees or less, but the mountain-shaped projecting piece (toe projecting piece) 22 effectively enters the interdental 32 and the periodontal pocket 33 and the back teeth 34 In order to obtain a shape that can reach the innermost part of the sheet, it is preferably molded within an allowable angle of 10 to 60 degrees.
ところで、ブラシ部２０におけるヒール部ｈ側の形状については、短辺方向Ｍから見て緩やかな山形状を為す態様や、全体が均一な平面状を為す態様が考え得る。また、短辺方向Ｍから見たブラシ部２０の幅について、トゥ部ｔとヒール部ｈとを異なる幅とする態様が考えられ、例えば、トゥ部ｔよりもヒール部ｈを幅狭とする態様が可能である。さらには、ブラシ部２０のトゥ部ｔとヒール部ｈとを分割した状態で植毛台１１に配置する態様、即ちトゥ部ｔとヒール部ｈとの境界に所定幅の隙間を設ける態様も可能である。
By the way, as for the shape of the brush portion 20 on the heel portion h side, a mode in which a gentle mountain shape is seen from the short side direction M and a mode in which the whole is a uniform flat shape can be considered. Further, with regard to the width of the brush portion 20 viewed from the short side direction M, a mode in which the toe portion t and the heel portion h are different widths can be considered, for example, a mode in which the heel portion h is narrower than the toe portion t.

Furthermore, a mode in which the toe portion t and the heel portion h of the brush portion 20 are arranged on the flocking table 11 in a state where the brush portion 20 is divided, that is, a mode in which a gap having a predetermined width is provided at the boundary between the toe portion t and the heel portion h is possible. is there.
このように、ブラシ部２０のトゥ部ｔ先端に成形された山形状の突片（トゥ突片）２２が、長辺方向Ｌから見て頂点角θ２が鋭角を為し且つトゥ側辺が略鉛直状の稜線２３を為すと共にヒール側辺がヒール方向へ直線的若しくは曲線的な下り傾斜の稜線２３を為して形成されることによって、長手方向Ｌへ往復スライドするように歯３０の表面を磨く際に、ブラシ体のトゥ側辺とヒール側辺との異なる傾斜角によって夫々最適な抵抗力による歯垢除去が可能になると共に、図５（ａ），（ｂ）に示すように、山形状の突片（トゥ突片）２２が並列する歯３０の歯間３２や歯周ポケット３３に効果的に入り込み、当該歯間３２や歯周ポケット３３に付着した歯垢を確実且つ効率良く除去することができ、さらには、図５（ｃ）に示すように、突片（トゥ突片）２２が奥歯３４の最奥にまで届いて磨き残し無く歯磨きすることが可能になる。また、二以上の突片（トゥ突片）２２が成形されている場合には、図５（ｄ）に示すように、歯３０に対して歯ブラシ１０を縦に当てがって磨くことで、突片（トゥ突片）２２が歯周ポケット３３に効果的に入り込んで、確実且つ効率良く磨くことも可能となる。
As described above, the peak-shaped projecting piece (toe projecting piece) 22 formed at the tip of the toe part t of the brush part 20 has an acute angle of the vertex angle θ2 when viewed from the long side direction L, and the toe side is substantially the same. The surface of the tooth 30 is formed so as to reciprocate in the longitudinal direction L by forming the vertical ridge line 23 and the heel side edge forming a ridge line 23 that is linearly or curved downwardly inclined in the heel direction. When polishing, the different inclination angles between the toe side and the heel side of the brush body enable plaque removal with optimum resistance, respectively, as shown in FIGS. 5 (a) and 5 (b). The shaped protruding pieces (toe protruding pieces) 22 effectively enter the interdental spaces 32 and the periodontal pockets 33 of the teeth 30 arranged side by side, and the plaque adhering to the interdental 32 and the periodontal pockets 33 is reliably and efficiently removed. Furthermore, as shown in FIG. Piece (toe projecting pieces) 22 makes it possible to toothpaste, not leaving Shine reached up to the deepest of the back teeth 34. When two or more projecting pieces (toe projecting pieces) 22 are formed, as shown in FIG. 5 (d), by brushing the toothbrush 10 vertically against the teeth 30, The projecting piece (toe projecting piece) 22 effectively enters the periodontal pocket 33 and can be polished reliably and efficiently.
以上のように、本実施例にかかる歯ブラシ１０によれば、ブラシ部２０のトゥ部ｔ先端に成形された突片（トゥ突片）２２が、短辺方向Ｍ及び長辺方向Ｌの何れから見ても鋭角な頂点角θ１，θ２を有する山形状に形成されていることで、該突片（トゥ突片）２２における最上端箇所２６が点状を為して存在することとなり、該最上端箇所２６が歯間３２や歯周ポケット３３など狭い隙間に効果的に入り込んで、歯垢を確実且つ効率良く除去することが可能となる。
As described above, according to the toothbrush 10 according to the present embodiment, the protruding piece (toe protruding piece) 22 formed at the tip of the toe portion t of the brush portion 20 is from either the short side direction M or the long side direction L. Since it is formed in a mountain shape having acute vertex angles θ1 and θ2 even when viewed, the uppermost end portion 26 of the projecting piece (toe projecting piece) 22 exists in a dot shape, The upper end portion 26 effectively enters a narrow gap such as the interdental 32 or the periodontal pocket 33, so that the plaque can be reliably and efficiently removed.
なお、突片（トゥ突片）２２における最上端と最下端との寸法差Ｔについては、特に限定するものではなく、上記頂点角θ１，θ２の角度及びブラシ部２０全体の幅，長さ，高さ等によって適宜決定されることとなるが、歯周ポケット３３や歯間３２に効果的に入り込む形状を考慮し、好ましくは２～５ｍｍの許容寸法内で成形され、例えばブラシ部２０の高さの下方約１/３から略中央位置位より上方部分が突片（トゥ突片）２２となるように成形される。
The dimensional difference T between the uppermost end and the lowermost end of the projecting piece (toe projecting piece) 22 is not particularly limited, and the angles of the vertex angles θ1 and θ2 and the width, length, Although it is appropriately determined depending on the height and the like, it is preferably molded within an allowable dimension of 2 to 5 mm in consideration of the shape that effectively enters the periodontal pocket 33 and the interdental 32, for example, the height of the brush portion 20 It is formed so that the upper part from about 1/3 below the approximate center position becomes a protruding piece (toe protruding piece) 22.
上記の通り成形された本実施形態にかかる歯ブラシ１０において、図９（ａ）に示すように、植毛台１１の所定中間位置よりトゥ側（トゥ部ｔ）を下方へ屈曲させる態様が考え得る。かかる態様を採用しない場合には、突片（トゥ突片）２２がヒール部ｈよりも高く成形されているため、特に突片（トゥ突片）２２における最上端と最下端との寸法差Ｔが大きい場合などでは、歯磨きの際にヒール部ｈが上手く歯に当接しない場合も想定できるが、トゥ側（トゥ部ｔ）を下方へ屈曲させる態様を採ることで、突片（トゥ突片）２２の最上端箇所２６とヒール部ｈとの高さ位置に差がなくなり、ヒール部ｈが効果的に作用すると共に、屈曲した植毛台１１のトゥ部ｔ先端に配された突片（トゥ突片）２２が奥歯３４の最奥部を磨く際に有効に機能する。
In the toothbrush 10 according to the present embodiment formed as described above, a mode in which the toe side (toe portion t) is bent downward from a predetermined intermediate position of the flocking table 11 as shown in FIG. When this aspect is not adopted, the projecting piece (toe projecting piece) 22 is formed to be higher than the heel portion h. Therefore, in particular, the dimensional difference T between the uppermost end and the lowermost end of the projecting piece (toe projecting piece) 22. In the case where the heel part h is not brushed well, it can be assumed that the heel part h does not contact the teeth well. However, by adopting a mode in which the toe side (toe part t) is bent downward, the protruding piece (toe protruding piece) ) There is no difference in the height position between the uppermost end portion 26 of the 22 and the heel portion h, the heel portion h acts effectively, and the protruding piece (toe) disposed at the tip of the toe portion t of the bent flocking table 11 The projecting piece 22 functions effectively when the innermost portion of the back teeth 34 is polished.
図６乃至図８は、本発明にかかる歯ブラシ１０の第二の実施形態を示す説明図であり、図６は長辺方向から見た要部拡大図、図７は平面拡大図、図８は使用状態説明図である。
6 to 8 are explanatory views showing a second embodiment of the toothbrush 10 according to the present invention. FIG. 6 is an enlarged view of a main part viewed from the long side direction, FIG. 7 is an enlarged plan view, and FIG. FIG.
本実施形態にかかる歯ブラシ１０は、植毛台１１のヒールに把持部１２を備え且つ該植毛台１１に複数のブラシ体が植毛されてブラシ部２０を構成して成る歯ブラシ１０であって、上記第一の実施形態と相違する点は、ブラシ部２０のヒール部ｈに、複数の山形状の突片（ヒール突片）２４が成形されている点であって、該突片（ヒール突片）２４の形状に特徴を有する。
A toothbrush 10 according to the present embodiment is a toothbrush 10 that includes a grip portion 12 on a heel of a flocking table 11 and has a brush unit 20 formed by embedding a plurality of brush bodies on the flocking table 11. The difference from the embodiment is that a plurality of mountain-shaped projecting pieces (heel projecting pieces) 24 are formed on the heel portion h of the brush unit 20, and the projecting pieces (heel projecting pieces). Characterized by 24 shapes.
該突片（ヒール突片）２４は、ブラシ部２０のヒール部ｈにおいて、長辺方向Ｌに一列に連続して成形される。なお、該突片（ヒール突片）２４の成形位置については、長辺方向Ｌに一列であれば特に限定するものではなく、例えば図７に示すように、短辺視略中央箇所を頂点として成形される。
The protruding pieces (heel protruding pieces) 24 are continuously formed in a row in the long side direction L at the heel portion h of the brush portion 20. The forming position of the projecting piece (heel projecting piece) 24 is not particularly limited as long as it is in a line in the long side direction L. For example, as shown in FIG. Molded.
該突片（ヒール突片）２４の成形数に限定はなく、長辺Ｌの寸法によっても成形可能な数は変わるため、本発明の突片（ヒール突片）２４が発揮する作用効果に変わりの無い範囲内で適時決定すれば足りるが、好ましくはヒール部ｈに二から二十の突片（ヒール突片）２４が成形される。少なくとも二の突片（ヒール突片）２４が存在しないと本発明の機能を果たさず、また、二十一以上の突片（ヒール突片）２４を成形するとヒール部ｈの長辺範囲内にあまりに多くの突片（ヒール突片）２４が存在することとなって、通常の歯ブラシ形状とさほど変化ないこととなるためである。なお、図面では五の突片（ヒール突片）２４を成形した場合について示している。
There is no limitation to the number of moldings of the projecting pieces (heel projecting pieces) 24, and the number that can be formed varies depending on the dimension of the long side L. Therefore, the operational effect exhibited by the projecting pieces (heel projecting pieces) 24 of the present invention is changed. It is sufficient that the time is determined within the range where there is no gap, but preferably two to twenty protrusions (heel protrusions) 24 are formed on the heel part h. If at least two protrusions (heel protrusions) 24 are not present, the function of the present invention is not achieved. If more than twenty-one protrusions (heel protrusions) 24 are formed, they are within the long side range of the heel portion h. This is because there are too many projecting pieces (heel projecting pieces) 24 and the shape of the toothbrush is not so different. In the drawing, a case where five protrusions (heel protrusions) 24 are formed is shown.
本実施形態における突片（ヒール突片）２４の個々の形状的特徴については、上記第一の実施形態で説明した突片（トゥ突片）２２における形状的特徴と同様であるため、説明は省略する。
また、本実施形態において、短辺方向Ｍから見たブラシ部２０の幅をトゥ部ｔとヒール部ｈ夫々異なる幅とする態様や、ブラシ部２０のトゥ部ｔとヒール部ｈとを分割した状態で植毛台１１に配置する態様についても、上記第一の実施形態と同様であるため、説明は省略する。 The individual shape characteristics of the projecting piece (heel projecting piece) 24 in the present embodiment are the same as the shape characteristics of the projecting piece (toe projecting piece) 22 described in the first embodiment, and therefore the description will be omitted. Omitted.
In the present embodiment, the width of thebrush part 20 viewed from the short side direction M is different from the toe part t and the heel part h, and the toe part t and the heel part h of the brush part 20 are divided. Since the aspect arrange | positioned in the flocking base 11 in the state is the same as that of said 1st embodiment, description is abbreviate | omitted.
また、本実施形態において、短辺方向Ｍから見たブラシ部２０の幅をトゥ部ｔとヒール部ｈ夫々異なる幅とする態様や、ブラシ部２０のトゥ部ｔとヒール部ｈとを分割した状態で植毛台１１に配置する態様についても、上記第一の実施形態と同様であるため、説明は省略する。 The individual shape characteristics of the projecting piece (heel projecting piece) 24 in the present embodiment are the same as the shape characteristics of the projecting piece (toe projecting piece) 22 described in the first embodiment, and therefore the description will be omitted. Omitted.
In the present embodiment, the width of the
なお、該突片（ヒール突片）２４の全体的な形状的特徴については、短辺方向Ｍから見た両側端方向への傾斜や、長辺方向Ｌから見たヒール側辺の傾斜について、全ての突片（ヒール突片）２４につき直線的若しくは曲線的に統一する態様のほか、各突片（ヒール突片）２４ごと直線的と曲線的とを交互に配するなど混合する態様も可能であり、さらには、各突片（ヒール突片）２４の頂点角θ１，θ２について、全てを同角度とするか夫々異なる角度とするかは任意に決定可能である。
In addition, as for the overall shape characteristics of the projecting piece (heel projecting piece) 24, regarding the inclination toward the both ends as viewed from the short side direction M and the inclination of the heel side viewed from the long side direction L, In addition to a mode in which all the projecting pieces (heel projecting pieces) 24 are unified linearly or curvilinearly, a mode in which each projecting piece (heel projecting piece) 24 is alternately arranged linearly and curvilinearly is also possible. Furthermore, it is possible to arbitrarily determine whether the vertex angles θ1 and θ2 of the respective projecting pieces (heel projecting pieces) 24 are the same angle or different angles.
ところで、各突片（ヒール突片）２４の最上端位置については、図６（ａ）に示すように、全て同じに成形する態様のほか、各突片（ヒール突片）２４ごとに異なった最上端位置となるよう成形する態様が考え得る。このとき、図６（ｂ）に示すように、突片（トゥ突片）２２の最上端位置を、突片（ヒール突片）２４より高く成形する態様も可能である。かかる態様を採用する際、突片（トゥ突片）２２の最上端位置と突片（ヒール突片）２４の最上端位置との寸法差Ｔ１については任意であり、例えば歯周ポケット３３の深さに比例して当該寸法差Ｔ１を大きくした方が歯ブラシ１０としての効果を発揮するが、概ね好ましくは２～４ｍｍの寸法差Ｔ１の範囲内で適宜決定される。
また、突片（トゥ突片）２２と突片（ヒール突片）２４の最下端位置について、図面では同じ位置とする態様のみ示したが、夫々異なる最下端位置とする態様も可能であり、例えば、突片（ヒール突片）２４の最下端位置を突片（トゥ突片）２２の最下端位置よりも低い位置とする態様が考え得る。 By the way, the uppermost position of each projecting piece (heel projecting piece) 24 is different for each projecting piece (heel projecting piece) 24 in addition to the same shape as shown in FIG. An embodiment in which the uppermost position is formed can be considered. At this time, as shown in FIG. 6B, a mode in which the uppermost end position of the protruding piece (toe protruding piece) 22 is formed higher than the protruding piece (heel protruding piece) 24 is also possible. When such an aspect is adopted, the dimensional difference T1 between the uppermost end position of the projecting piece (toe projecting piece) 22 and the uppermost end position of the projecting piece (heel projecting piece) 24 is arbitrary, for example, the depth of theperiodontal pocket 33 Increasing the dimensional difference T1 in proportion to the thickness exhibits the effect as the toothbrush 10, but is preferably determined as appropriate within a range of the dimensional difference T1 of 2 to 4 mm.
In addition, as for the lowermost positions of the projecting pieces (toe projecting pieces) 22 and the projecting pieces (heel projecting pieces) 24, only the mode in which the same position is shown in the drawing is shown. For example, a mode in which the lowermost position of the projecting piece (heel projecting piece) 24 is lower than the lowermost position of the projecting piece (toe projecting piece) 22 can be considered.
また、突片（トゥ突片）２２と突片（ヒール突片）２４の最下端位置について、図面では同じ位置とする態様のみ示したが、夫々異なる最下端位置とする態様も可能であり、例えば、突片（ヒール突片）２４の最下端位置を突片（トゥ突片）２２の最下端位置よりも低い位置とする態様が考え得る。 By the way, the uppermost position of each projecting piece (heel projecting piece) 24 is different for each projecting piece (heel projecting piece) 24 in addition to the same shape as shown in FIG. An embodiment in which the uppermost position is formed can be considered. At this time, as shown in FIG. 6B, a mode in which the uppermost end position of the protruding piece (toe protruding piece) 22 is formed higher than the protruding piece (heel protruding piece) 24 is also possible. When such an aspect is adopted, the dimensional difference T1 between the uppermost end position of the projecting piece (toe projecting piece) 22 and the uppermost end position of the projecting piece (heel projecting piece) 24 is arbitrary, for example, the depth of the
In addition, as for the lowermost positions of the projecting pieces (toe projecting pieces) 22 and the projecting pieces (heel projecting pieces) 24, only the mode in which the same position is shown in the drawing is shown. For example, a mode in which the lowermost position of the projecting piece (heel projecting piece) 24 is lower than the lowermost position of the projecting piece (toe projecting piece) 22 can be considered.
このように、ブラシ部２０のトゥ部ｔ先端に成形された山形状の突片（トゥ突片）２２並びにヒール部ｈに成形された山形状の突片（ヒール突片）２４が、長辺方向Ｌから見て頂点角θ２が鋭角を為し且つトゥ側辺が略鉛直状の稜線２３を為すと共にヒール側辺がヒール方向へ直線的若しくは曲線的な下り傾斜の稜線２３を為して形成されることによって、長手方向Ｌへ往復スライドするように歯３０の表面を磨く際に、ブラシ体のトゥ側辺とヒール側辺との異なる傾斜角によって夫々最適な抵抗力による歯垢除去が可能になると共に、図８（ａ），（ｂ）に示すように、山形状の突片（トゥ突片）２２及び突片（ヒール突片）２４が並列する歯３０の歯間３２や歯周ポケット３３に効果的に入り込み、当該歯間３２や歯周ポケット３３に付着した歯垢を確実且つ効率良く除去することができ、さらに突片（トゥ突片）２２の最上端位置を突片（ヒール突片）２４より高く成形する態様を採用することで、図８（ｃ）に示すように、突片（トゥ突片）２２が奥歯３４の最奥にまで届いて磨き残し無く歯磨きすることが可能になる。また、二以上の突片（トゥ突片）２２が成形されている場合には、上記第一の実施形態と同様、図５（ｄ）に示すように、歯３０に対して歯ブラシ１０を縦に当てがって磨くことで、突片（トゥ突片）２２が歯周ポケット３３に効果的に入り込んで、確実且つ効率良く磨くことも可能となる。
As described above, the mountain-shaped protrusion (toe protrusion) 22 formed at the tip of the toe t of the brush portion 20 and the mountain-shaped protrusion (heel protrusion) 24 formed at the heel portion h have long sides. When viewed from the direction L, the apex angle θ2 forms an acute angle, the toe side forms a substantially vertical ridge line 23, and the heel side forms a straight or curved downward ridge line 23 in the heel direction. As a result, when the surface of the tooth 30 is polished so as to slide back and forth in the longitudinal direction L, plaque removal by the optimum resistance force is possible due to the different inclination angles of the toe side and the heel side of the brush body. At the same time, as shown in FIGS. 8 (a) and 8 (b), the inter-protrusion 32 and the periodontium of the tooth 30 in which the mountain-shaped projecting piece (toe projecting piece) 22 and the projecting piece (heel projecting piece) 24 are arranged in parallel. It effectively enters the pocket 33 and enters the interdental 32 or periodontal pocket 33. By adopting a mode in which the worn plaque can be removed reliably and efficiently, and the uppermost end position of the protruding piece (toe protruding piece) 22 is formed higher than the protruding piece (heel protruding piece) 24, FIG. As shown in (c), the projecting piece (toe projecting piece) 22 reaches the innermost part of the back teeth 34, and it is possible to brush without leaving any brushes. Further, when two or more projecting pieces (toe projecting pieces) 22 are formed, as in the first embodiment, as shown in FIG. By being applied to and polished, the projecting piece (toe projecting piece) 22 effectively enters the periodontal pocket 33 and can be polished reliably and efficiently.

It is possible to remove it reliably and efficiently.
なお、突片（トゥ突片／ヒール突片）２２，２４における最上端と最下端との寸法差Ｔについては、上記第一の実施形態と同様、特に限定するものではなく、上記頂点角θ１，θ２の角度及びブラシ部２０全体の幅，長さ，高さ等によって適宜決定されることとなるが、歯周ポケット３３や歯間３２に効果的に入り込む形状を考慮し、好ましくは２～５ｍｍの許容寸法内で成形され、例えばブラシ部２０の高さの下方約１/３から略中央位置位より上方部分が突片（トゥ突片／ヒール突片）２２，２４となるように成形される。
The dimensional difference T between the uppermost end and the lowermost end of the projecting pieces (toe projecting pieces / heel projecting pieces) 22 and 24 is not particularly limited as in the first embodiment, and the vertex angle θ1 is not limited. , Θ2 and the width, length, height, etc. of the entire brush portion 20 are determined as appropriate, and preferably 2 to 2 in consideration of the shape that effectively enters the periodontal pocket 33 and the interdental 32. Molded within an allowable dimension of 5 mm, for example, so that the upper part of the brush part 20 is approximately 1/3 below the height of the brush part 20, and the upper part becomes the projecting pieces (toe projecting pieces / heel projecting pieces) 22, 24. Is done.
上記の通り成形された本実施形態にかかる歯ブラシ１０において、図９（ｂ）に示すように、植毛台１１の所定中間位置よりトゥ側（トゥ部ｔ）を下方へ屈曲させる態様が考え得る。かかる態様を採用しない場合には、突片（トゥ突片）２２が突片（ヒール突片）２４よりも高く成形されて夫々の最上端位置の寸法差Ｔ１が大きい場合に、歯磨きに際し該突片（ヒール突片）２４が上手く歯に当接しない場合も想定できるが、トゥ側（トゥ部ｔ）を下方へ屈曲させる態様を採ることで、突片（トゥ突片）２２の最上端箇所２６と突片（ヒール突片）２４の最上端箇所２６との高さ位置に差がなくなり、該突片（ヒール突片）２４が効果的に作用すると共に、屈曲した植毛台１１のトゥ部ｔ先端に配された突片（トゥ突片）２２が奥歯３４の最奥部を磨く際に有効に機能する。
