Abstract

To solve problems that, in a conventional brush, the tip of bristles gradually opens due to an individual polishing way that the number of bristles touching teeth is reduced and dregs on the teeth can be hardly cleaned. Therefore, a toothbrush has a brush-like form with bristle length formed less than a half (roughly 5 mm±1 mm) of the conventional toothbrush in order to prevent each bristle from being opened. The bristle length made less than the half of that of the conventional toothbrush in the height from the root of the bristles makes the bristle tips soft and rigid in inverse proportion with the bristle length. Slightly harder selection of the toothbrush in accordance with individual dentine and gums increases teeth-brushing sensation and cleans dregs better. The opening of each bristle takes longer time compared with the conventional toothbrush as a result of slower consumption of each bristle.SOLUTION: As the height of bristles from the root in a part of brushing teeth is formed less than a half of those of a conventional toothbrush, softness and proper rigidity are added to a tip of the bristles in inverse proportion with the height of the bristles. Tooth-brushing sensation is increased and dregs of teeth are cleaned better. A part of bristles in which the tips are gradually opened due to an individual brushing way is formed less than a half (roughly 5 mm±1 mm) of the toothbrush bristles in the height from the root, so that moderate rigidity is added to the tips. Consequently, the opening speed of each of the bristles becomes slower, thus the toothbrush lasts longer.

Description

歯磨ブラシの１つである。歯ブラシは毛先が開いてしまえば歯を磨く機能が失なわれる。その為に長期間機能を失なわない為、毛の付根からの毛の長さを従来の歯ブラシの半分以下（５ｍｍ±１ｍｍ程）に形成した刷毛状に成形した歯ブラシに関するものである。It is one of the toothpaste brushes. If the tip of the toothbrush is opened, the function of brushing the teeth will be lost. Therefore, in order not to lose the function for a long period of time, the present invention relates to a toothbrush formed into a brush shape in which the length of the hair from the root of the hair is less than half (about 5 mm ± 1 mm) of the conventional toothbrush.

Problems to be solved by the invention

従来の歯ブラシは各個人の磨き方によって毛先が少しづつ開いてしまい歯に当る毛先の本数は少なくなる。
歯についたカスは落ちにくくなる。そこで１本１本の毛が開きにくくする為に毛の長さを従来の歯ブラシの半分以下（５ｍｍ±１ｍｍ程）に形成した刷毛状に成形する歯ブラシである。
毛の付根から毛の高さが従来の歯ブラシの半分以下の短かさにすると毛の長さに逆比例して毛先は柔軟さと硬さが加わる。
歯ブラシは各個人の歯質、歯ぐきに合わせて選択されているが多少硬めである事が歯を磨いている感覚が強まり、歯のカスは良く落ちる。これで１本１本の毛の開き具合は従来の歯ブラシに比べて遅くなる。
１本１本の毛の消耗度が低くなる為である。With conventional toothbrushes, the tips of the bristles open little by little depending on how each individual brushes, and the number of bristles that hit the teeth decreases.
The residue on the teeth is hard to remove. Therefore, in order to make it difficult for each bristles to open, the toothbrush is formed into a brush shape in which the length of the bristles is less than half (about 5 mm ± 1 mm) of the conventional toothbrush.
If the height of the hair from the root of the hair is less than half that of a conventional toothbrush, the tip of the hair becomes softer and harder in inverse proportion to the length of the hair.
The toothbrush is selected according to the tooth substance and gums of each individual, but the fact that it is a little stiff strengthens the feeling of brushing the teeth, and the tooth residue is often removed. This makes the opening of each bristles slower than that of a conventional toothbrush.
This is because the degree of wear of each hair is low.

Means to solve problems

歯を磨く部分の毛の付根から毛の高さを従来の歯ブラシの半分以下の短かさに形成するので、毛の高さに逆比例して毛先は柔軟さと適度の硬さが加わる。歯を磨いている感覚が強まり、歯のカスは良く落ちる。各個人の磨き方によって毛先が少しづつ開いてしまう部分は毛の付根から毛の高さが半分以下（５ｍｍ±１ｍｍ程）に形成されているので毛先に適度の硬さが加わる。
これで１本１本の毛の開き具合の速度は遅くなり歯ブラシは永持ちする。Since the height of the bristles is formed to be less than half the height of the conventional toothbrush from the root of the bristles in the part where the teeth are brushed, the tips of the bristles are added with flexibility and moderate hardness in inverse proportion to the height of the bristles. The feeling of brushing your teeth is strengthened, and the residue on your teeth is often removed. Since the height of the hair is less than half (about 5 mm ± 1 mm) from the root of the hair in the part where the tip of the hair opens little by little depending on the brushing method of each individual, appropriate hardness is added to the tip of the hair.
This slows down the opening of each bristles and makes the toothbrush last longer.

Claims

This toothbrush is formed into a brush shape by forming the height of the hair from the root of the hair to less than half (5 mm ± 1 mm) of the conventional toothbrush.

The toothbrush according to claim 1, wherein the height of the bristles is slightly shortened only around the outer side of the root of the bristles and the toothbrush is formed into a brush shape.

The bristles are brush-shaped toothbrushes according to claim 1, which are made of a light synthetic resin such as nylon.

The handle is made of a hard synthetic resin such as polypropylene, and the rubber part is made of a soft synthetic resin such as EPDM or polypropylene. The toothbrush is formed into a brush shape according to claim 1.

The rubber part fixes the rubber ring so that the handle does not fall from the finger of the person who brushes the teeth.
This rubber ring is a toothbrush molded into a brush shape according to claim 1, wherein only the bottom surface is fixed and the upper surface is a finger.
