Description
本発明は、子供用歯ブラシ及び子供用歯ブラシの製造方法に関する。
The present invention relates to a child toothbrush and a method for manufacturing a child toothbrush.
一般的な大人用の歯ブラシの繊維（ブラシ毛）の直径は０．１８～０．２２ｍｍであるのに対して、子供用の歯ブラシの繊維（ブラシ毛）の直径は０．１２～０．１５ｍｍが主流である。
これは、太い繊維は硬いため、子供の歯茎を傷めやすいこと、更には大人が磨いてあげる際に、子供を痛がらせることが多いのが理由である。一方、子供が全く痛がらない程度まで繊維の直径を細くすると、本来の目的である歯ブラシとしての清掃能力が不足するとう問題が生じる。
そのため、従来の子供用が歯ブラシでは、歯ブラシの柄の構造を変える、ブラシ部分を繊維からエラストマーに変更するなど様々な工夫がされている。 The diameter of the fiber (brush bristle) of a general adult toothbrush is 0.18 to 0.22 mm, while the diameter of the fiber (brush bristle) of a child toothbrush is 0.12 to 0.15 mm. Is the mainstream.
This is because the thick fibers are hard and easily damage the gums of children, and often hurt children when they are polished by adults. On the other hand, if the diameter of the fiber is reduced to such an extent that the child does not hurt at all, there arises a problem that the cleaning ability as a toothbrush, which is the original purpose, is insufficient.
Therefore, in a conventional toothbrush for a child, various measures have been taken, such as changing the structure of the handle of the toothbrush and changing the brush portion from a fiber to an elastomer.

そのため、従来の子供用が歯ブラシでは、歯ブラシの柄の構造を変える、ブラシ部分を繊維からエラストマーに変更するなど様々な工夫がされている。 The diameter of the fiber (brush bristle) of a general adult toothbrush is 0.18 to 0.22 mm, while the diameter of the fiber (brush bristle) of a child toothbrush is 0.12 to 0.15 mm. Is the mainstream.
This is because the thick fibers are hard and easily damage the gums of children, and often hurt children when they are polished by adults. On the other hand, if the diameter of the fiber is reduced to such an extent that the child does not hurt at all, there arises a problem that the cleaning ability as a toothbrush, which is the original purpose, is insufficient.
Therefore, in a conventional toothbrush for a child, various measures have been taken, such as changing the structure of the handle of the toothbrush and changing the brush portion from a fiber to an elastomer.
しかしながら、歯面や歯間の洗浄効果が不十分となり、また歯茎のマッサージ効果の低く、さらには高価となり、社会的要求を満たすものではなかった。 このように、子供用の歯ブラシは、清掃性を確保する程度に繊維直径を細くするだけに留めている製品が多く、子供達が痛がる点は解消しきれていなかった。
However, the cleaning effect on the tooth surface and between teeth is insufficient, the massage effect on the gums is low, and the cost is high, and it does not satisfy social demands. As described above, many toothbrushes for children are only designed to make the fiber diameter small enough to ensure cleanability, and the point at which children hurts has not been completely solved.
また、歯ブラシの繊維直径を先端部から徐々に変化させ、歯と歯茎の境目の隙間（歯肉溝）の歯垢や歯と歯の間の歯垢を除去する歯ブラシが、特許文献１において提案されている。この特許文献１では、化学的処理により、合成樹脂製繊維の先端部にテーパ面を形成し、円柱状の繊維の先端部を細くするテーパ化処理された歯ブラシが提案されている。
Further, Patent Document 1 proposes a toothbrush that gradually changes the fiber diameter of the toothbrush from the tip portion and removes plaque in the gap (gingival sulcus) between teeth and gums and plaque between teeth. ing. Patent Document 1 proposes a tapered toothbrush in which a tapered surface is formed at a tip portion of a synthetic resin fiber by a chemical treatment, and the tip portion of a cylindrical fiber is thinned.
上記したように、子供用の歯ブラシは、清掃性を確保する程度に繊維直径を細くするだけに留めている製品が多く、子供達が歯磨き中に痛がる点は解消しきれていないのが現状である。
As mentioned above, many toothbrushes for children only keep the fiber diameter small enough to ensure cleanability, and the point at which children hurt while brushing their teeth has not been completely solved. It is the current situation.
この課題を解消するために、特許文献１に記載されるような化学処理により、子供用の歯ブラシの合成樹脂製繊維の先端部にテーパ面を形成し、円柱状の繊維の先端部を細くするテーパ化処理を子供用歯ブラシに適用することが考えられる。
In order to solve this problem, a tapered surface is formed at the tip of the synthetic resin fiber of the toothbrush for children by a chemical treatment as described in Patent Document 1, and the tip of the cylindrical fiber is made thin. It is conceivable to apply the tapering process to a child toothbrush.
しかしながら、繊維の先端部を細くするテーパ化処理を施すと、結果的に繊維の先端部が尖り、子供達が歯磨き中に痛がる点を十分解消できないという技術的課題があった。
However, there is a technical problem that, when the taper treatment for thinning the tip of the fiber is performed, the tip of the fiber is sharpened as a result, and it is not possible to sufficiently eliminate the point where children suffer pain during brushing.
本発明は、子供達が歯磨き中に痛がる点を十分解消することができる子供用歯ブラシ及び子供用歯ブラシの製造方法を提供することである。

The toothed brush head 4 is formed by the flocking base portion 23 and the brush 3.ブ ラ シ The brush 3 is formed by implanting a plurality of brush bristles 31 at a plurality of locations on the flocked base portion 23. The brush bristles 31 are made of synthetic resin fibers. Examples of the synthetic resin fiber material of the brush hair 31 include polyamide resins such as 6,6-nylon, 6-nylon, 12-nylon, 6,10-nylon, 6,12-nylon, and polyolefins such as polyethylene and polypropylene.

2A is a side view of the child toothbrush 1 of FIG. 1, FIG. 2B is a front view of the child toothbrush 1 of FIG. 1, and FIG. FIG. 4 is an explanatory view for explaining the size of the child toothbrush 1 of FIG.
図２（ａ）、図２（ｂ）において、基体２は、ポリプロピレン樹脂、ポリアセタール樹脂、ポリオキシメチレン樹脂等の樹脂で一体に形成されている。また、子供用歯ブラシ１は、全長（Ｌ）がＬ＝１１０．０～１８０．５ｍｍ（図４参照）の範囲で形成されている。
2A and 2B, the base 2 is integrally formed of a resin such as a polypropylene resin, a polyacetal resin, and a polyoxymethylene resin. Further, the child toothbrush 1 is formed so that the total length (L) is in a range of L = 110.0 to 180.5 mm (see FIG. 4).
図２（ａ）において、子供用歯ブラシヘッド４は、植毛ベース部２３の先端側の厚さ（Ａ）がＡ＝４．７０ｍｍ（図４参照）、植毛ベース部２３の基端側（柄側）の厚さ（Ｂ）がＢ＝５．００ｍｍ（図４参照）で形成されている。
基端側（柄側）の厚さ（Ｂ）はＢ＝６．００ｍｍ～４．００ｍｍの間が適切である。
Ｂが薄い方がより子供の口の中に入りやすいが、薄すぎると植毛する部分が十分に取れないことからこの程度が適切である。
つまり、この基端側（柄側）の厚さ（Ｂ）を普通の歯ブラシより薄く形成している
子供用歯ブラシヘッド４も、できるだけ小さく形成している。
具体的には、植毛部分の根元からの距離をできるだけ取らない大きさで形成されている。具体手的には、植毛部分の根元から先頭方向、左右方向への余白の大きさが、０．３０～１．５０ｍｍの間が適切である。 In FIG. 2A, thechild toothbrush head 4 has a thickness (A) of A = 4.70 mm (see FIG. 4) on the distal end side of the flocked base portion 23, and has a proximal end side (handle side) of the flocked base portion 23. ) Has a thickness (B) of B = 5.00 mm (see FIG. 4).
The thickness (B) on the base end side (handle side) is suitably between B = 6.00 mm and 4.00 mm.
The thinner B is easier to enter the child's mouth, but if it is too thin, the hair transplanted portion cannot be sufficiently removed, so this degree is appropriate.
That is, thechild toothbrush head 4 whose base end (handle side) thickness (B) is formed thinner than a normal toothbrush is also formed as small as possible.
Specifically, it is formed in such a size that the distance from the root of the flocked portion is as small as possible. Specifically, it is appropriate that the size of the margin in the head direction and the left and right direction from the root of the flocked portion is between 0.30 to 1.50 mm.

The thickness (B) on the base end side (handle side) is suitably between B = 6.00 mm and 4.00 mm.
The thinner B is easier to enter the child's mouth, but if it is too thin, the hair transplanted portion cannot be sufficiently removed, so this degree is appropriate.
That is, the
Specifically, it is formed in such a size that the distance from the root of the flocked portion is as small as possible. Specifically, it is appropriate that the size of the margin in the head direction and the left and right direction from the root of the flocked portion is between 0.30 to 1.50 mm.
前記子供用歯ブラシヘッド４のブラシ毛３１の植毛面は、図２（ａ）に示す長さ（Ｃ）がＣ＝１４．５０ｍｍ、図２（ｂ）に示す幅（Ｄ）がＤ＝８．２８ｍｍ（図４参照）で形成されている。
The flocked surface of the brush bristles 31 of the child toothbrush head 4 has a length (C) shown in FIG. 2A of C = 14.50 mm and a width (D) shown in FIG. 28 mm (see FIG. 4).
前記子供用歯ブラシヘッド４のブラシ毛３１は、図２（ａ）に示す植毛ベース部２３の表面から突出した長さであるところの毛丈（Ｅ）がＥ＝５．５～６．５ｍｍ（図４参照）の範囲で形成されている。
このように毛の長さが短いことから、口の小さい（口を大きくあけてくれない）幼児等の口の中の奥まで侵入させることができ、磨き残しを防止できる。
この為には、出来るだけ毛の長さが短い方がいいが、そのままでは、毛が固くなり幼児が痛がるという恐れがある。そこで、次の工夫がなされている。
Ｅ＝５．５～６．５ｍｍが現在のところ、様々な制約条件のなかで最適値である。もっとも、Ｅ＝３．０ｍｍ～８．０ｍｍ程度でも、一定の効果がある。 Thebrush bristles 31 of the child toothbrush head 4 have a bristle length (E), which is a length protruding from the surface of the flocking base portion 23 shown in FIG. 2A, where E = 5.5 to 6.5 mm ( (See FIG. 4).
Since the length of the hair is short as described above, it is possible to penetrate deep into the mouth of an infant or the like with a small mouth (the mouth is not greatly opened), and the unpolished portion can be prevented.
For this purpose, it is better that the hair length is as short as possible, but if it is kept as it is, there is a risk that the hair will become hard and the infant will be hurt. Therefore, the following contrivance has been made.
E = 5.5-6.5 mm is currently the optimum value among various constraints. However, there is a certain effect even when E = about 3.0 mm to 8.0 mm.

図３に示すように、ブラシ毛３１は、直径（φ）がφ≦０．１０ｍｍ（図４参照）の条件で形成されている。
このように直径を小さくしたことから、毛自体は弾力性を増すことができる。より細くすれば、より弾力性を増すことができ、Ｅの長さを短くできる。
しかし、細くなると、歯にブラシ毛３１が歯茎などに刺さりこれが今度は痛みの原因になる。
その痛みを緩和するために、ブラシ毛３１の先端部は、丸めて形成されている。
しかし、丸みを帯びさせることには一定の限界があり、現在のところφは０．０７ｍｍ～０．１５ｍｍの範囲が可能な範囲と考えている。
そして、最適値は、φ＝０．０９ｍｍ～０．１１ｍｍの範囲であると現在のところ考えている。
もっとも、より柔らかい素材をブラシ毛３１に使用できれば、変化することが考えられる。
また、直径を小さくしたことから、密集的に毛を植えることが可能となっている。
これによって、複数の毛が同時に歯茎に当たることになり、痛みを抑えることが可能になっている。
具体的には、７０本を２つ折りにして植えた１４０本が、一つのブラシの束当たりのブラシ毛３１の本数としている。これは、通常の２倍以上である。つまり、通常の歯ブラシの場合１束当たりの本数は２５本程度である。
ここで、本発明の密集的な植毛とは、一つの束当たりの本数が、５０本以上をいう。より適切値は、６０本以上であり、最適値は７５本以上である。
図２の例では、この束が、先頭側では２つ左右に並んでおり、その次が３つの列が５列並んでいる。そのため、図２の例では、１７束存在している。
なお、より薄くするため植毛した部分の植毛ベース部２３部分を傾斜部２２よりも薄くできればより好適である。 As shown in FIG. 3, the brush bristles 31 are formed under the condition that the diameter (φ) is φ ≦ 0.10 mm (see FIG. 4).
Since the diameter is reduced in this manner, the bristles themselves can increase elasticity. If it is made thinner, the elasticity can be further increased, and the length of E can be shortened.
However, when it becomes thin, the brush bristles 31 stick to the teeth and the like, which in turn causes pain.
In order to alleviate the pain, the tip of the brush bristles 31 is rounded.
However, there is a certain limit to rounding, and at present, φ is considered to be in a range of 0.07 mm to 0.15 mm.
It is currently considered that the optimum value is in the range of φ = 0.09 mm to 0.11 mm.
However, if a softer material can be used for the brush bristles 31, it may change.
In addition, since the diameter is reduced, it is possible to plant hair densely.
As a result, a plurality of hairs hit the gums at the same time, so that pain can be suppressed.
Specifically, 140 brushes obtained by folding and planting 70 brushes are the number of brush bristles 31 per one brush bundle. This is more than twice as usual. That is, in the case of a normal toothbrush, the number per bundle is about 25.
Here, the dense flocking according to the present invention means that the number of bundles per bundle is 50 or more. A more appropriate value is 60 or more, and an optimal value is 75 or more.
In the example of FIG. 2, two of the bundles are arranged left and right on the leading side, and the next three rows are arranged in five rows. Therefore, in the example of FIG. 2, there are 17 bundles.
It is more preferable that the flockingbase portion 23 of the flocking portion can be made thinner than the inclined portion 22 in order to make it thinner.
このように直径を小さくしたことから、毛自体は弾力性を増すことができる。より細くすれば、より弾力性を増すことができ、Ｅの長さを短くできる。
