Description

本発明は、歯ブラシに関し、特にブリッスルを束ねてなるタフトが植毛台の複数の植毛孔に各々植設されている歯ブラシに関する。   The present invention relates to a toothbrush, and more particularly to a toothbrush in which tufts formed by bundling bristles are respectively implanted in a plurality of flock holes of a flocking table.

歯ブラシは、複数本のブリッスルを束ねてなるタフトを、植毛台に形成した複数の植毛孔に例えば平線を打ち込んだり熱で融着させる方法等によって植設固定することにより、複数のタフトからなるブラシ部を形成して得られるものである。また、歯ブラシは、歯面部、歯間部、歯頸部等の歯の部位や、前歯、奥歯等の歯の種類に応じた適切な刷掃を効率良く行うことができるようにすると共に、使用感を向上させるために、タフトの配置やブラシ部の全体の形状等に種々の工夫がなされている。   The toothbrush is composed of a plurality of tufts by, for example, implanting and fixing a tuft formed by bundling a plurality of bristles into a plurality of flock holes formed on the flocking table by, for example, driving a flat wire or fusing with heat. It is obtained by forming a brush part. In addition, the toothbrush can efficiently perform appropriate brushing according to the tooth part such as the tooth surface part, the interdental part, the tooth neck part, and the tooth type such as the front tooth and the back tooth. In order to improve the feeling, various ideas have been made on the arrangement of tufts, the overall shape of the brush portion, and the like.

例えば、植毛台に植設されるブリッスルの長さに差を設けることによって、歯列の凹凸や歯と歯ぐきの境目への到達感を向上させた歯ブラシが開示されている(例えば、特許文献1、特許文献2参照)。ブリッスルの長さに差を設けたこれらの歯ブラシは、植毛台の長手方向のブラシ面を鋸歯型にしたり(特許文献1)、植毛台の短手方向のブラシ面を山型にした(特許文献2)ものである。

For example, a toothbrush is disclosed in which a difference in the length of the bristle planted on the flocking table is provided to improve the dentition irregularities and the feeling of reaching the boundary between the teeth and the gums (for example, Patent Document 1). , See Patent Document 2). These toothbrushes with different bristle lengths have a sawtooth type brush surface in the longitudinal direction of the flocking table (Patent Document 1), or a short brush surface in the short direction of the flocking table (Patent Document). 2)
Japanese Utility Model Publication No. 62-106522 Japanese Utility Model Publication No. 3-82023

しかしながら、ブリッスルの長さに差を設けた歯ブラシでは、歯列の凹凸や歯と歯ぐきの境目への到達感が得られる反面、刷掃圧が長い毛先に集中して歯ぐきに対する刺激が強まり、歯列の凹凸や歯と歯ぐきの境目にフィットする感じやくまなく磨ける感じが劣ることになる。   However, with toothbrushes that have a difference in bristle length, a feeling of reaching the boundary between the teeth row and the boundary between the teeth and the gums can be obtained, but on the other hand, the brushing pressure concentrates on the long hair tips and the stimulation to the gums becomes stronger, The feeling of being able to fit in the unevenness of the dentition and the boundary between the teeth and the gums and to be able to polish all over is inferior.

本発明は、歯列や歯と歯ぐきの境目等へのフィット感、くまなく磨ける感じ、歯ぐきにやさしい感触等を効果的に得ることのできる歯ブラシを提供することを目的とする。   An object of this invention is to provide the toothbrush which can obtain effectively the feeling of fitting to the dentition, the boundary of a tooth | gear, a gum, etc., the feeling which can be brushed all over, the touch which is kind to a gum.

本発明は、ブリッスルを束ねてなるタフトが植毛台の複数の植毛孔に各々植設されている歯ブラシであって、前記タフトを構成するブリッスルの先端を連ねたブラシ面が、前記植毛台の短手方向と対向する側面側から見た際にμ字形状となっており、前記植毛台の長手方向と対向する先端側から見た際に中央部分を頂部とする山状又は上に凸の弧状の形状となっており、かつ前記タフトを構成するブリッスルは、先端がテーパー形状となっており、かつ最外周に配置される前記植毛孔の外縁を結んだ環状線によって囲まれる領域を前記植毛台の植毛領域として、該植毛領域の面積に対する前記植毛孔の面積の総和の割合が35%以上となっている歯ブラシを提供することにより、上記目的を達成したものである。   The present invention provides a toothbrush in which tufts formed by bundling bristles are respectively planted in a plurality of follicle holes of a flocking table, and a brush surface connecting the tips of the bristles constituting the tuft is a short of the flocking table. When viewed from the side facing the hand direction, it is μ-shaped, and when viewed from the tip side facing the longitudinal direction of the flocking table, it is a mountain shape with the central portion at the top or an arc shape convex upward And the bristle constituting the tuft has a tapered tip and a region surrounded by an annular line connecting the outer edges of the flock holes arranged on the outermost periphery. The above object is achieved by providing a toothbrush in which the ratio of the total area of the flock holes to the area of the flocked area is 35% or more.

本発明の歯ブラシによれば、歯列や歯と歯ぐきの境目等へのフィット感、くまなく磨ける感じ、歯ぐきにやさしい感触等を効果的に得ることができる。   According to the toothbrush of the present invention, it is possible to effectively obtain a feeling of fitting to the dentition and the boundary between the teeth and the gums, a feeling of being able to polish all over, a feeling that is easy on the gums, and the like.

図1〜図4に示す本発明の好ましい一実施形態に係る歯ブラシ10は、把持部(図示せず)と植毛台11とこれらを連結する首部12とからなる歯ブラシ本体17の植毛台11に形成した複数の植毛孔13に、複数本のブリッスル14を束ねてなる毛束(タフト)15を各々植毛(植設)してブラシ部16を形成することにより構成される。   The toothbrush 10 which concerns on preferable one Embodiment of this invention shown in FIGS. 1-4 is formed in the flock base 11 of the toothbrush main body 17 which consists of a holding part (not shown), the flock base 11, and the neck part 12 which connects these. A plurality of bristle holes 13 are bundled (planted) with each other to form a brush portion 16.

すなわち、本実施形態の歯ブラシ10は、ブリッスル14を束ねてなるタフト15が歯ブラシ本体17の植毛台11の複数の植毛孔13に各々植設されている歯ブラシであって、タフト15を構成するブリッスル14の先端を連ねたブラシ面21は、植毛台11の短手方向Yと対向する側面側から見た際に、先端から中央に向かって一旦ブリッスルが長くなった後、下に凸の弧状に湾曲し、再度末端に向かってブリッスルが短くなるμ字形状となっており(図1,図4(b)参照)、かつ植毛台11の長手方向Xと対向する先端側から見た際に、中央部分を頂部とする山状の形状となっている(図2,図4(c)〜(e)参照)。また、最外周に配置される植毛孔13の外縁を結んだ環状線18(図3,図4(a)参照)によって囲まれる領域を植毛台11の植毛領域19として、この植毛領域19の面積に対する植毛孔13の面積の総和の割合が35%以上となっている。   That is, the toothbrush 10 of this embodiment is a toothbrush in which tufts 15 formed by bundling bristles 14 are respectively planted in the plurality of flock holes 13 of the flocking table 11 of the toothbrush body 17, and the bristles constituting the tufts 15. The brush surface 21 that is connected to the tip 14 of the bristles 14 has a bristles that are once elongated from the tip toward the center when viewed from the side facing the short direction Y of the flocking table 11, and then has a downwardly convex arc shape. When it is viewed from the tip side facing the longitudinal direction X of the flocking table 11, it is curved and has a μ-shape that shortens the bristle toward the end again (see FIGS. 1 and 4B). It has a mountain shape with the central portion at the top (see FIGS. 2, 4C to 4E). Further, the area surrounded by the annular line 18 (see FIGS. 3 and 4A) connecting the outer edges of the flock holes 13 arranged on the outermost periphery is defined as the flocked area 19 of the flocked table 11, and the area of the flocked area 19 The ratio of the sum total of the area of the flock hole 13 with respect to is 35% or more.

本実施形態では、歯ブラシ本体17は、例えばポリプロピレン、ABS樹脂等の合成樹脂からなり、その植毛台11の平坦な表面には、各タフト15の配設位置に対応させて、後述する所定の配設ピッチで略正方形の平面形状を備える多数(複数)の植毛孔13が、例えば2〜5mmの深さで開口形成されている。各植毛孔13には、タフト15が、好ましくは平線30を打ち込む方法によって、植毛台11の表面からの高さである毛丈が好ましくは7〜14mmとなるように各々植設されている。   In the present embodiment, the toothbrush body 17 is made of a synthetic resin such as polypropylene or ABS resin, and the flat surface of the flocking table 11 has a predetermined arrangement described later corresponding to the arrangement position of each tuft 15. A large number (a plurality) of flock holes 13 having a substantially square planar shape at an installation pitch are formed with a depth of, for example, 2 to 5 mm. In each flock hole 13, tufts 15 are preferably implanted by a method of driving a flat wire 30 so that the hair height, which is the height from the surface of the flocking table 11, is preferably 7 to 14 mm. .

各タフト15を構成するブリッスル14は、例えばナイロン等の合成樹脂や、豚毛などの天然素材からなる、例えば6〜10mil(0.15〜0.25mm)の太さを有するフィラメント材であって、これを例えば数本〜数十本束ねることによってタフト15が形成される。またブリッスル14の先端部分は、テーパー形状となっている。   The bristle 14 constituting each tuft 15 is a filament material having a thickness of, for example, 6 to 10 mil (0.15 to 0.25 mm) made of a synthetic material such as nylon or a natural material such as pig hair. The tuft 15 is formed by bundling several to several tens of these, for example. The tip of the bristle 14 is tapered.

本実施形態では、各タフト15が植設される植毛孔13は、各々、例えば縦横0.8〜2.5mmの大きさの、角部が円弧状に面取りされた略正方形の平面形状を備えており、その一方の対角線が植毛台11の長手方向Xに沿うように配置され、当該長手方向Xに連設して3列、合計16箇所に形成されている。また各列の植毛孔13は、隣接する列の隣り合う植毛孔13間に位置するように各々配置されて、千鳥状に配設されている。   In this embodiment, each flock hole 13 in which each tuft 15 is implanted has a substantially square planar shape with corners chamfered in an arc shape, for example, with a size of 0.8 to 2.5 mm in length and width. One of the diagonal lines is arranged along the longitudinal direction X of the flocking table 11, and is arranged in three rows in a row in the longitudinal direction X, for a total of 16 locations. Moreover, the flock holes 13 in each row are arranged so as to be positioned between adjacent flock holes 13 in adjacent rows, and are arranged in a staggered manner.

そして、本実施形態では、タフト15を構成するブリッスル14の先端を連ねたブラシ面21は、図1に示すように、植毛台11の短手方向Yと対向する側面側から見た際に、好ましくは30〜60mm、さらに好ましくは40〜50mmの曲率半径で下に凸の弧状に湾曲しているとともに、先端部や後端部の双方がそれぞれ先端側および後端側に向けて直線上あるいは曲線状に斜めに切り揃えられたμ字形状となっている(図4(b)参照)。曲率半径が30〜60mmとなっていることにより、歯列の湾曲に対して面で接触するため、刷掃圧が特定のブリッスルに集中することがなくフィット感が高まり、先端部や後端部の双方が斜めに切り揃えられていることにより、ブラッシングの際ブリッスル14が歯ぐきに突き当たることがなく歯ぐきに対する刺激も小さくなる。   And in this embodiment, when the brush surface 21 which connected the front-end | tip of the bristle 14 which comprises the tuft 15 was seen from the side surface opposite to the transversal direction Y of the flocking table 11, as shown in FIG. Preferably, it is curved in a convex arc with a curvature radius of 30 to 60 mm, more preferably 40 to 50 mm, and both the front end and the rear end are linearly directed toward the front end and the rear end, respectively. It is a μ-shape that is obliquely cut in a curved line (see FIG. 4B). Since the radius of curvature is 30 to 60 mm, the surface comes into contact with the curvature of the dentition, so that the brushing pressure does not concentrate on a specific bristle, and the feeling of fitting increases, and the front end and rear end Since both of these are cut diagonally, the bristles 14 do not hit the gums during brushing, and the stimulation on the gums is reduced.

さらに、本実施形態では、タフト15を構成するブリッスル14の先端を連ねたブラシ面21は、図2に示すように、植毛台11の長手方向Xと対向する先端側から見た際に、中央部分を頂部とする好ましくは120〜160度、さらに好ましくは130〜150度の頂角の山状の形状となっている(図4(c)〜(e)参照)。山状の形状の頂角が120〜160度となっていることにより、歯と歯ぐきの境目を磨く時に面で接触するため、刷掃圧が特定のブリッスルに集中することがなく、フィット感が高まるという利点が得られることになる。なお、本発明では、中央部分を頂部とする凸形状は、山状の他、上に凸の弧状の形状とすることもできる。上に凸の弧状の形状とする場合には、その曲率半径を好ましくは8〜30mm、さらに好ましくは12〜25mmとすることができる。   Furthermore, in this embodiment, the brush surface 21 connecting the tips of the bristle 14 constituting the tuft 15 is centered when viewed from the tip side facing the longitudinal direction X of the flocking table 11, as shown in FIG. The peak is preferably 120 to 160 degrees, and more preferably 130 to 150 degrees, with a peak angle (see FIGS. 4C to 4E). Since the apex angle of the mountain shape is 120 to 160 degrees, contact is made with the surface when polishing the boundary between the teeth and the gums, so the brushing pressure does not concentrate on a specific bristle, and the fit is The advantage of increasing will be obtained. In addition, in this invention, the convex shape which makes a center part a top part can also be made into an arc-shaped shape convex upwards other than a mountain shape. In the case of an upwardly convex arc shape, the radius of curvature is preferably 8 to 30 mm, and more preferably 12 to 25 mm.

また、本実施形態では、最外周に配置される植毛孔13の外縁を結んだ環状線18によって囲まれる植毛領域19の面積(図4(a)参照)に対する、植毛孔13の面積の総和の割合は、35%以上となっており、好ましくは35〜70%、さらに好ましくは40〜60%となっている。植毛領域19の面積に対する植毛孔13の面積の総和の割合が35%以上となっていることにより、刷掃圧が少数のブリッスルに集中することがなく、その結果、歯ぐきに対する刺激も小さくなるという利点が得られることになる。   In the present embodiment, the total area of the flocked hole 13 with respect to the area of the flocked region 19 (see FIG. 4A) surrounded by the annular line 18 that connects the outer edges of the flocked hole 13 arranged on the outermost periphery. The ratio is 35% or more, preferably 35 to 70%, more preferably 40 to 60%. Since the ratio of the total area of the flock holes 13 to the area of the flocked region 19 is 35% or more, the brushing pressure does not concentrate on a small number of bristle, and as a result, the stimulation on the gums is also reduced. Benefits will be gained.

また、本実施形態によれば、タフト15を構成するブリッスル14は、先端がテーパー形状となっているので、ブリッスル14の植毛密度が高くなったブラシ部16の刷掃時における感触をよりソフトにすることが可能になる。   In addition, according to the present embodiment, since the bristle 14 constituting the tuft 15 has a tapered tip, the feel at the time of brushing the brush portion 16 in which the bristle 14 has a high flocking density is softened. It becomes possible to do.

なお、本実施形態では、植毛台11の各列における隣接する植毛孔13間の長手方向Xの中心配設ピッチは、例えば1.2〜4.0mmとなっており、隣接する列間の短手方向Yの中心配設ピッチは、例えば1.5〜5.0mmとなっている。   In this embodiment, the center arrangement pitch in the longitudinal direction X between adjacent flock holes 13 in each row of the flocking table 11 is, for example, 1.2 to 4.0 mm, and the short distance between adjacent rows. The center arrangement pitch in the hand direction Y is, for example, 1.5 to 5.0 mm.

また、本実施形態によれば、植毛孔13は、略正方形の平面形状を有しており、一方の対角線を植毛台11の長手方向Xに沿わせて配置することにより、上述のようなブラシ部16の全体に亘ってブリッスル14の偏りがなく、略均一にブリッスル14の植毛密度が高くなった、植毛領域19の面積に対する植毛孔13の面積の総和の割合が35%以上の歯ブラシ10を容易に形成することが可能になる。   Moreover, according to this embodiment, the flock hole 13 has a substantially square planar shape, and by arranging one diagonal line along the longitudinal direction X of the flocking table 11, the brush as described above. The toothbrush 10 in which the ratio of the total area of the flock holes 13 to the area of the flocked region 19 in which the flocking density of the bristles 14 is substantially uniform and the flocking density of the bristles 14 is increased uniformly throughout the portion 16 is 35% or more. It can be easily formed.

なお、本発明は上記実施形態に限定されることなく種々の変更が可能である。例えば、植毛孔は、略正方形の平面形状を備え、一方の対角線を植毛台の長手方向に沿わせて配置する必要は必ずしもなく、例えば略菱形又は略六角形の平面形状や、円形の平面形状を備えるものであっても良い。また、タフトは、平線を介して植毛孔に植設されるものである必要は必ずしもなく、融着植毛等によって植設されるものであっても良い。   The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the flocking hole has a substantially square planar shape, and it is not always necessary to arrange one diagonal line along the longitudinal direction of the flocking table, for example, a substantially rhombus or hexagonal planar shape, or a circular planar shape. May be provided. Further, the tuft does not necessarily have to be planted in the flock hole through a flat line, and may be planted by fusion flocking or the like.

以下、実施例及び比較例により、本発明の歯ブラシをさらに詳細に説明するが、本発明はこれらに限定されるものではない。   Hereinafter, although the toothbrush of this invention is demonstrated in detail by an Example and a comparative example, this invention is not limited to these.
