Description

本発明は植毛された毛束の特質を究めて、歯ブラシの弱点である両端部の毛のコシを強めて、歯磨き効果を高めるとともに、磨いたときにかかる植毛部への加圧の力の配分を究めて、これに対応した植毛部を創作することによって毛のひらきを防ぐことができるもので、従って長持ちできることを特徴とした歯ブラシに係わるものである。  The present invention investigates the characteristics of the hair bundle that has been flocked, strengthens the stiffness of the hair at both ends, which is a weak point of the toothbrush, enhances the toothbrushing effect, and distributes the pressure force applied to the flocked portion when brushed Therefore, the present invention relates to a toothbrush characterized in that it is possible to prevent the hair from spreading by creating a flocked portion corresponding to this, and therefore, it can last for a long time.

歯ブラシは、その使用時において歯に押圧し、これに押す力と引く力が作用して毛が撓い、且つ、なびいて毛並みが左右にひらく状態となる。而してこのひらきは端部に及ぶほど毛先のひらきの角度が大きくなる、これは端部の歯磨き効果が中ほどのそれより劣ることを示していることに他ならない。即ち、以前よく使われていた豚毛歯ブラシは、中ほどの毛のみ擦り切れて、最も使っている筈の先部は擦り切れない、元部も同様に擦り切れない、これは中ほどの部分が最も抵抗(歯磨き)効果があることのあらわれである。即ち先部へは自然に多く力が入っても毛が撓ってなびくので抵抗(歯磨き)効果が損なわれるのである。  When the toothbrush is used, the tooth is pressed against the tooth, and the pushing force and the pulling force act on the toothbrush to bend the bristles. Thus, the opening angle of the bristles increases as it reaches the end, which indicates that the brushing effect at the end is inferior to that at the middle. In other words, the pork toothbrush that was often used previously frays only the middle bristles, the tip of the most used wrinkle does not fray, and the original part does not fray as well, the middle part is the most resistant (Tooth brushing) Appears to be effective. That is, even if a large amount of force is naturally applied to the tip, the hair is bent and flutters, so the resistance (tooth brushing) effect is impaired.

「植毛された毛束は、毛足が短かくなると毛束自体のコシが強くなり、根元に近くなるほど更にコシが強くなり、合繊毛の場合変形しにくくなる。」この理論は背景技術の実案文献1−3を通じて一貫して述べているもので、本発明の原点なのである。而して歯ブラシは、その使用時において植毛部にどのような力の配分で作用しているのか、その場合の毛の撓いとなびきの具合はどうなのか、この点を見極めて、これを植毛部形態に反映されなければ、前記の理論は生かされないのである。 次に毛先の形状について述べると、現在市販されている歯ブラシはその多くが直線状である、これは前歯の表側の凸形と裏側の凹形に対応することができ、直線状の奥歯にも対応し、水平状(表現が適切でないかもしれないが)の咬合面にも適応することができるからで、これが最も普遍的である考えられる。而して歯ブラシはその使用時において毛が左右になびくことは周知の通りである、では、その分岐点になるのは植毛部のどの位置なのか、(ここが最も加圧を受ける箇所なのである。)しかしこれに普遍性はあるのか、而してこれを見出すのは極めて難しいことである、即ち前歯の表側と裏側は全く相反する形状であり、又奥歯の頬側、舌側、或いは咬合面、その一つ一つが形状が異なり、それぞれに歯ブラシへの当たり具合が異なることは自明の理であり、更に右側を磨くときと左側を磨くときは、力の入り方も自ずから異なることは論を俟たないことである、又磨き方も、人、様々で、癖もあることであり、これらを総合した当たり具合を見極めるには多数のデータと厳しい観察が必要とされるのである。而して、歯ブラシはその使用時において、意識するしないに拘らず先部へは自然に多く力が入るものであり、元部へのそれは少なめになるものである、しかし先部に入る力は、毛の撓いとなびき、となって作用するのである、これが先部の歯磨き効果を損ねるとともに、毛のひらきにつながるのである、元部も同様である。そしてそれらを総合して植毛部が最も強く加圧を受けるのは「約6:4の比率で元部寄りである。」ことを突き止めたのである。この箇所が、毛が左右になびく分岐点なのである。従って、この箇所の強い当たりを和らげ、平均した当たりになるように植毛部を形成すれば良いことになるのである。これは前記の「植毛された毛束の理論」に基づくもので、毛先が直線状であることを前提としている。  “The hair bundles that have been planted become stiffer in the hair bundle itself when the hair legs become shorter, and become stiffer the closer to the root, and in the case of synthetic fibres, they are less likely to be deformed.” It is described consistently through draft documents 1-3 and is the starting point of the present invention. Therefore, the toothbrush is used to determine what kind of force is acting on the flocked part at the time of use, and how the hair flexes and flutters in that case. The above theory will not be utilized unless it is reflected in the form. Next, when describing the shape of the bristles, most of the commercially available toothbrushes are linear, which can correspond to the convex shape on the front side of the front tooth and the concave shape on the back side, This is considered to be the most universal because it can also be applied to horizontal occlusal surfaces (although expression may not be appropriate). Thus, it is well known that the toothbrushes fly to the left and right when they are used. Then, the branching point is the position of the flocked part (this is the place that receives the most pressure) .) But is this universal, and it is extremely difficult to find it, that is, the front side and the back side of the front teeth are completely opposite shapes, and the buccal side, lingual side, or occlusion of the back teeth It is self-evident that the shape of each surface is different, and the contact with the toothbrush is different for each, and it is obvious that the way the force is applied is different when polishing the right side and the left side. There are many ways to polish them, how to polish them, and how to polish them. A lot of data and strict observations are required to determine how they are combined. Thus, when using a toothbrush, regardless of whether it is conscious or not, a lot of power is naturally applied to the front part, and that to the base part is less, but the force to enter the front part is This also acts as a flexion and fluttering of hair, which impairs the brushing effect of the front part and leads to the opening of the hair, as well as the base part. Then, by combining them, it was found that the flocked portion was most strongly pressed by "the portion closer to the base at a ratio of about 6: 4." This is the branching point where the hair flutters left and right. Therefore, it is only necessary to relieve the strong hit of this portion and form the flocked portion so as to have an average hit. This is based on the above-mentioned “theory of flocked hair bundles”, and assumes that the hair tips are linear.

前述のように本願歯ブラシは、植毛部形態が毛束にかかる圧力を分散する効果によって、植毛部全体が平均した当たりとなり、然も毛束の各々がその根元から作用するので前記の「植毛された毛束の理論」が生かされるのである。即ち、両端部は毛のコシガ強くなり、撓いとなびきを抑える効果を得ることができる。従って歯磨き効果が向上するとともに、毛並みのひらきを防ぐことができるので、長持ちできるのである。  As described above, the toothbrush of the present application is an average hit of the entire flocked portion due to the effect that the flocked portion form disperses the pressure applied to the follicle bundle, and since each follicle acts from its root, The theory of hair bundles is utilized. In other words, both ends become stronger and more effective in suppressing bending and fluttering. Therefore, the brushing effect is improved and the fluffing of the hair can be prevented, so that it can last for a long time.

前述のように本願植毛部は約6:4の加圧比重に則り形成されたものでスプーンの底状の曲線をもって形成されるものである。 而して本願の原点である背景技術の実案文献3件は、先に述べた豚毛歯ブラシが、その中程の毛が磨耗していることに着目して、植毛部は円弧状で事足りる、と考えて考案したものであり、加圧に偏りがあっても柄の取り付け角度によって調整可能と考えていたのである、しかしこの場合は、両端部の毛束の根元の部分に若干の遊びが残るのは否めず、これが毛のひらきになるので、背景技術3件の場合はこれを補うために傾斜植毛に構成したのである、然るに、本願植毛部は加圧比重に適応した形態であるが故に、両端部を含めて各々の毛束の根元に殆ど遊びがなく、前記の「植毛された毛束の理論」が生かされて、毛のひらきは僅少ですみ、歯磨き効果に影響を及ぼすほどのものではない、従って、本願歯ブラシは傾斜植毛を必要としないのである。  As described above, the flocked portion of the present application is formed in accordance with a pressure specific gravity of about 6: 4 and is formed with a curved bottom of the spoon. Thus, the three background art drafts that are the origin of the present application are based on the fact that the above-described pork toothbrush has worn the middle hair, and the flocked portion is sufficient in an arc shape. In this case, there is some play at the root of the hair bundle at both ends. However, it is not possible to leave, but since this becomes a fluff of hair, in the case of 3 background arts, it is configured to be inclined flocking to make up for this, however, the flocking portion of the present application is a form adapted to the specific gravity of pressure. Therefore, there is almost no play at the root of each hair bundle, including both ends, and the above-mentioned “theory of the hair bundle that has been flocked” is utilized, so that the amount of hair is minimal and affects the brushing effect. Therefore, the present toothbrush does not require inclined flocking Than is.

前述のように本願歯ブラシは、植毛部がスプーンの底状の曲線をもって形成されていることと、直線状の毛先との相関関係により、「植毛された毛束の理論」が生かされて、両端部の毛のひらきは僅少ですみ歯磨き効果に影響を及ぼすほどのものではなく、中ほどの毛もひらかず、而も、両サイドの毛のひらきも極めて小さく、これも歯磨き効果を損ねるほどのものではない、従って本願歯ブラシは、スプーンの底状の曲線からなる植毛部と、曲線の内側部分に複数の毛束が垂直状に植毛され、直線状の毛先を有することによってその効果を得ることができる。  As described above, the toothbrush of the present application is based on the fact that the flocked part is formed with a bottom-like curve of the spoon and the linear hair tip, and the `` theory of flocked hair bundle '' is utilized, The hair on both ends is very small and does not affect the tooth brushing effect. The hair on the middle side does not open, and the hair on both sides is extremely small. This also impairs the tooth brushing effect. Therefore, the toothbrush of the present application has the effect of having a straight hair tip having a straight hair tip in which a plurality of hair bundles are vertically planted on the inner portion of the curved hair portion of the spoon. Obtainable.
