Abstract

PROBLEM TO BE SOLVED: To provide a toothbrush with excellent brushing effect on any parts inside the oral cavity as the tufts of bristles can be freely moved in every direction, frontward, backward, left, right, upward or downward, according to the brushing force and the tip of bristles can excellently fit the various unevenness inside the oral cavity. SOLUTION: The root of a tuft of bristles 1 is held by an elastic material 2 for holding the tuft of bristles, and the elastic material 2 for holding the tuft of bristles is connected to a bristle planting surface 4 of a head 3 at a position C-C with a smaller area of the cross section than that of the cross section at a position B-B with the largest area of the cross section. Further, in connecting the elastic material 2 for holding the tuft of bristles, the area SC of the cross section of the connecting part is 3/4 of or less than the area SB of the cross section at the position with the largest area of the cross section of the elastic material 2 for holding the tuft of bristles.

【発明が解決しようとする課題】しかしながら、前記ヘッド部に切り込みを入れたものは、ブラッシング中に切り込み部が塑性変形する可能性があり、歯面への毛先のフィット性が低下するおそれがあった。 [SUMMARY OF THE INVENTION However, those cuts to the head portion, there is a possibility that portions cut during brushing is plastically deformed, possibly fit the bristle tips of the tooth surface is reduced there were.

【0004】また、前記切り込み部に弾性体を充填したものは、切り込み部を境目に植毛部単位で可動(可撓) Further, those filled with elastic material to the cut portion is cut portion movable bristle portion units the boundary (flexible)
するため、可動の必要のない部分までも動いてしまい、 In order to, will move even need no portion of the movable,
歯面への毛先のフィット性が低下するおそれがあった。 Fit of the bristle tips of the tooth surface may decrease.

【0005】また、前記刷毛束の根元部をバネ構造で保持したものは、ヘッド部の背面と刷毛束保持側端部との間にバネなどを入れるための空間が必要であり、この空間部分に水や食べかすなどが入り込みやすく、衛生的でなく、さらに、その構造上、ヘッド部が厚くなり、口腔内での操作性が低下するものが多く見られた。 Further, those of root portion of the brush bundle held by a spring structure, it is necessary space for placing a spring between the back and the brush bundle holding end of the head portion, the space portion to to enter more easily water or food particles, rather than hygienic, further its structure, the head portion becomes thick, the operability in the oral cavity were observed many things to decrease.

【0006】また、前記刷毛束の根元部を弾性体で保持したものとしては、ヘッド部の枠組みを硬質樹脂で形成し、この硬質樹脂からなる枠組みの中に弾性体を保持させるようにしたもの(実開昭63−93829号)、ヘッド部植毛面に弾性台を形成し、この上に刷毛束を植毛したもの(実開平1−81924号)があるが、前者の場合、硬質樹脂の枠組みが必要であるため、ヘッド部縁から植毛面の刷毛束までの寸法が大きくなり過ぎ、口腔内での操作性が通常の歯ブラシに比べて低下するとともに、刷毛束の動きも十分にとることができず、また、後者の場合、弾性体台の伸縮のみで刷毛束を可動としているため、理想的な刷毛束の動きを実現することは難しかった。 Further, those of root portion of the brush bunch as those held in the elastic body, the framework of the head portion is formed of a hard resin, and so as to hold the elastic member in a framework consisting of the hard resin (Japanese Utility Model No. 63-93829), to form a resilient base to the head portion flocked surface, there are those flocking the brush bundle on the (real-Open No. 1-81924), in the former case, the framework of the hard resin since it is necessary, too large size of the head portion edge to brush bundle of bristles face, together with the operation of in the oral cavity is reduced as compared with conventional toothbrushes, also take a sufficient movement of the brush bundle can not, in the latter case, since the movable brush bundle only an elastic body stand stretching, it is difficult to realize the movement of the ideal brush bundles.

【0007】本発明は、上記事情の下になされたもので、ブラッシング力に応じて刷毛束が前後左右、上下方向のあらゆる方向に自在に動くことができ、刷毛先が口腔内のさまざまな凹凸に良好にフィットし、口腔内のどのような部位に対しても優れた刷掃効果を上げることができる歯ブラシを提供することを目的する。 [0007] The present invention has been made under the above circumstances, the left and right front and rear brush bundles in accordance with the brushing forces, can move freely in all directions in the vertical direction, various irregularities brush destination in the oral cavity good fit, which aims to provide a toothbrush which can increase the good brushing effect on any site in the oral cavity.

【課題を解決するための手段】図1に、本発明の歯ブラシの原理構造を示す。 1 SUMMARY OF THE INVENTION illustrates the principle construction of the toothbrush of the present invention. (a)は本発明の歯ブラシにおける1本の刷毛束部分の模式拡大側面図、(b)は(a) (A) is a schematic enlarged side view of a brush bundle portion of one of the toothbrushes of the present invention, (b) is (a)
中のB−B線位置における横断面図、(c)は(a)中のC−C線位置における横断面図である。 Cross-sectional view along a line B-B position in, (c) is a transverse cross-sectional view taken along line C-C position in (a).

【0009】本発明の歯ブラシは、前記目的を達成するため、刷毛束1の根元部を刷毛束保持用の弾性体2で保持し、この刷毛束保持用弾性体2をその横断面最大面積位置(刷毛束2の長手方向と垂直方向の最大断面積位置)B−Bよりも面積の小さな横断面位置C−Cにおいてヘッド部3の植毛面4に結合したものである。 [0009] toothbrushes of the present invention, in order to achieve the above object, hold the root portion of the brush bundle 1 by the elastic body 2 for brush bundle holding, the brush bundle holding elastic member 2 that cross-sectional maximum area position those attached to flocked surface 4 of the head portion 3 in a small cross-section position C-C of the area than B-B (maximum cross-sectional area position in the longitudinal direction and the vertical direction of the brush bundle 2).

【0010】なお、前記結合部であるC−C線位置の横断面面積S Cは、刷毛束保持用弾性体2の横断面最大面積位置であるB−B線位置における横断面面積S Bの3 [0010] Incidentally, the cross-sectional area S C of the line C-C position is the coupling portion of the cross-sectional area S B line B-B position which is a cross-sectional maximum area position the brush bundle elastic holding member 2 3
/4以下の面積とすることが好ましく、より好ましくは2/3以下の面積とする。 / 4 it is preferable that the following areas, and more preferably an area of ​​2/3 or less.

【0011】このような構成とした場合、図2(a) [0011] When such a configuration, FIGS. 2 (a)
(b)中に矢印と鎖線で示すように、刷毛束1を保持した刷毛束保持用弾性体2がブラッシング時に作用する力によって前後左右、上下方向のあらゆる方向に自在に動くことができるようになる。 As shown by the arrow and dashed line in (b), the left and right front and rear by the force brush bundle elastic holding member 2 which holds the brush bundle 1 is applied during brushing, such that it can move freely in all directions in the vertical direction Become. このため、刷毛先が口腔内のさまざまな凹凸に良好にフィットし、口腔内のどのような部位に対しても優れた刷掃効果を上げることができる。 Therefore, brush destination better fit various irregularities in the oral cavity, it is possible to increase the good brushing effect on any site in the oral cavity.

【0012】前記結合部の横断面面積S Cは、刷毛束1 [0012] cross-sectional area S C of the coupling portion, brush bundle 1
の動きを左右する。 It affects the movement of. 横断面面積S Cが大き過ぎると、刷毛束保持用弾性体2が傾くことができず、刷毛束1の動きは刷毛束保持用弾性体2の上下方向の伸縮のみとなり、最適な動きが得られない。 If cross-sectional area S C is too large, it can not be brush bunch elastic holding member 2 tilts, the movement of the brush bundle 1 is only the vertical expansion and contraction of the brush bundle holding elastic member 2, obtained optimal motion It is not. 逆に、横断面面積S Cが小さ過ぎると、ブラッシング時に作用する力で刷毛束が過度に動いてしまい、刷掃効果が低下する恐れがある。 Conversely, when the cross-sectional area S C is too small, brush bundle forces acting during brushing would excessively moving, there may be deteriorated brushing effect.
したがって、刷毛束保持用弾性体2の材質を加味しながら、前記横断面最大面積S Bの3/4以下の範囲内で、 Therefore, while considering the material of the brush bundle elastic holding member 2, within the range of 3/4 of the cross-sectional maximum area S B,
