Description

本発明は、歯ブラシに関するものであり、特に、植毛部の毛切り形状（側面から見た植毛部の形状）を工夫した歯ブラシに係るものである。 The present invention relates to a toothbrush, and particularly relates to a toothbrush in which the hair cutting shape of the flocked portion (the shape of the flocked portion viewed from the side) is devised.

歯ブラシは、歯に付着した歯垢や歯間の食物残渣等を除去し、更には歯肉のマッサージを行なうために、従来より広く使用されている。 Toothbrushes have been widely used in the past to remove plaque adhering to teeth, food residues between teeth, and to massage gingiva.

歯ブラシとしては、柄の先端に設けた植毛台に毛を植設してなるものが従来より知られている。 Conventionally known toothbrushes are made by planting bristles on a flocking table provided at the tip of a handle.

植毛台には、複数本の毛（ブリッスル）を束ねてなる毛束（ブリッスル束）が植設される場合が多いが、多数本の毛が各別に植設されることもある。 In many cases, a hair bundle (bristle bundle) obtained by bundling a plurality of hairs (brissles) is planted on the hair transplant table, but a large number of hairs may be planted separately.

また、植毛台に植毛される毛は、一般にナイロン等の合成樹脂製のものが用いられるが、動物の毛を用いたものも使用されている。 Moreover, as for the hair to be flocked on the flocking table, synthetic resin such as nylon is generally used, but hair using animal hair is also used.

実開平６−１５４号公報は、先端をテーパ状に形成した毛束を植毛台に植設してなる歯ブラシ（以下「従来の歯ブラシ」という。）を開示している。 Japanese Utility Model Laid-Open No. 6-154 discloses a toothbrush (hereinafter referred to as “conventional toothbrush”) in which a hair bundle having a tapered tip is implanted in a flocking table.

従来の歯ブラシは、毛束の先端をテーパ状に形成することにより、歯間部や歯と歯茎との境目等に十分に毛先が届くようにしたものである。
実開平６−１５４号公報 In the conventional toothbrush, the tip of the bristles is formed in a tapered shape so that the tip of the bristles can reach the interproximal part or the boundary between the teeth and gums.

しかるに、上記従来の歯ブラシは、他の一般的に使用されている歯ブラシと同様に、特に、上下の前歯の内側、奥歯（臼歯）等が磨きにくいという問題を有する。 However, the conventional toothbrush has a problem that it is difficult to polish the inner side of the upper and lower front teeth, the back teeth (molar teeth) and the like, in the same manner as other commonly used toothbrushes.

本発明は、上記従来の歯ブラシ等における上述の如き問題を解決し、上下の前歯の内側、奥歯等についても磨きやすくした歯ブラシを提供しようとしてなされたものである。 The present invention has been made to solve the above-mentioned problems in the conventional toothbrushes and to provide a toothbrush that can be easily polished on the inner side of the upper and lower front teeth, the back teeth, and the like.

上記課題を解決するために、本発明は、下記の歯ブラシを提供する。 In order to solve the above problems, the present invention provides the following toothbrushes.

柄の先端に設けた植毛台に毛を植設してなる植毛部を備えた歯ブラシにおいて、
該植毛部の毛切り形状は、植毛部の長さ方向において、植毛部の中央部が植毛台の植毛面と略平行であり、該中央部の前後各端から植毛部の前後各端に向って植毛台に徐々に接近する方向に傾斜していることを特徴とする歯ブラシ。 In a toothbrush having a flocked portion formed by planting hair on a flocking table provided at the tip of the handle,
The hair cutting shape of the flocked portion is such that, in the length direction of the flocked portion, the central portion of the flocked portion is substantially parallel to the flocked surface of the flocked table, and extends from the front and rear ends of the central portion to the front and rear ends of the flocked portion. A toothbrush that is inclined in a direction that gradually approaches the flocking table.

本発明による歯ブラシにおいては、植毛部における中央部の前後各端から植毛部の前後各端に向って植毛台に徐々に接近する方向に傾斜している傾斜部を上又は下の歯列弓における各前歯の内側、各奥歯等に一本ずつ好ましく押し当てることができると共に、歯ブラシの柄を略水平に保持した状態で植毛台の植毛面と略平行な植毛部の中央部を上又は下の歯列弓における複数本の前歯に好ましく押し当てることができる。即ち、本発明による歯ブラシは、上下の前歯の内側、奥歯等についても極めて磨きやすいものである。 In the toothbrush according to the present invention, in the upper or lower dental arch, the inclined portion that is inclined in the direction of gradually approaching the flock base from the front and rear ends of the central portion of the flocked portion toward the front and rear ends of the flocked portion. Each tooth can be preferably pressed to the inside of each front tooth, each back tooth, etc., and the central part of the flocked part that is substantially parallel to the flocked surface of the flocking table with the toothbrush handle held substantially horizontal It can be preferably pressed against a plurality of front teeth in the dental arch. That is, the toothbrush according to the present invention is extremely easy to polish the inside and back teeth of the upper and lower front teeth.

本発明による歯ブラシは、柄１の先端に設けた植毛台３に毛５、５・・・を植設してなる植毛部７を備えている点においては、従来の歯ブラシと同様である。 The toothbrush by this invention is the same as that of the conventional toothbrush in the point provided with the flocking part 7 formed by planting the hair 5,5 ... in the flocking table 3 provided in the front-end | tip of the handle | pattern 1. FIG.

植毛部７は、図１、図３に示すように、複数本の毛５、５・・・を束ねてなる多数の毛束９、９・・・を植毛台３に植設してなるものであってもよいが、図２に示すように、多数本の毛５、５・・・を各別に植毛台３に植設してなるものであってもよい。 As shown in FIG. 1 and FIG. 3, the hair transplanting part 7 is formed by planting a plurality of hair bundles 9, 9... However, as shown in FIG. 2, a plurality of hairs 5, 5...

また、植毛台３に植毛される毛５、５・・・は、ナイロン等の合成樹脂製のものが好ましく用いられるが、動物の毛を用いたものもであっても差し支えない。 Further, the hairs 5, 5... To be implanted on the flocking table 3 are preferably made of synthetic resin such as nylon, but may be made of animal hair.

しかして、本発明においては、植毛部７の毛切り形状は、植毛部７の長さ方向（柄１の軸方向）において、植毛部７の中央部１１が植毛台３の植毛面３ａと略平行であり、該中央部１１の前後各端２１、２３から植毛部７の前後各端１３、１５に向って植毛台３に徐々に接近する方向に傾斜している。 Therefore, in the present invention, the hair cutting shape of the flocked portion 7 is substantially the same as the flocked surface 3a of the flocked table 3 with the central portion 11 of the flocked portion 7 in the length direction of the flocked portion 7 (the axial direction of the handle 1). They are parallel and are inclined from the front and rear ends 21 and 23 of the central portion 11 toward the front and rear ends 13 and 15 of the flocked portion 7 so as to gradually approach the flocking table 3.

即ち、植毛部７における中央部１１の前端２１から植毛部７の前端１３まで前側の傾斜部１７が形成され、植毛部７における中央部１１の後端２３から植毛部７の後端１５まで後側の傾斜部１９が形成されている。 That is, a front inclined portion 17 is formed from the front end 21 of the central portion 11 to the front end 13 of the flocked portion 7 in the flocked portion 7, and from the rear end 23 of the central portion 11 to the rear end 15 of the flocked portion 7 in the flocked portion 7. A side inclined portion 19 is formed.

中央部１１と前側の傾斜部１７との間の境部をなす中央部１１の前端２１と、中央部１１と後側の傾斜部１９との間の境部をなす中央部１１の後端２３とは、それぞれ丸みを帯びさせることが望ましい。 A front end 21 of the central portion 11 that forms a boundary between the central portion 11 and the front inclined portion 17 and a rear end 23 of the central portion 11 that forms a boundary between the central portion 11 and the rear inclined portion 19. It is desirable to round each.

なお、本発明による植毛部７の毛切り形状は、植毛部７の長さ方向（柄１の軸方向）に関する側面形状としての毛切り形状であり、植毛部７の幅方向の形状については何等の制限を有するものではない。図３参照。 In addition, the hair cutting shape of the hair transplant part 7 by this invention is a hair cutting shape as a side surface shape regarding the length direction (axis direction of the handle 1) of the hair transplant part 7, and what about the shape of the width direction of the hair transplant part 7? It does not have any restrictions. See FIG.

次に、本発明による歯ブラシの使用状態の数例について、説明する。 Next, several examples of the usage state of the toothbrush according to the present invention will be described.

図４に示す事例においては、歯ブラシの柄１を略水平に保持した状態で植毛台３の植毛面３ａと略平行な植毛部７の中央部１１を上又は下の歯列弓における複数本の前歯３１、３１・・・に押し当てている。 In the example shown in FIG. 4, a plurality of pieces in the upper or lower dental arch at the central portion 11 of the flocked portion 7 substantially parallel to the flocked surface 3 a of the flocked table 3 with the toothbrush handle 1 held substantially horizontally. It is pressed against the front teeth 31, 31.

図５に示す事例においては、植毛部７における後側の傾斜部１９を下歯弓列における歯３３の内側に押し当てている。 In the example shown in FIG. 5, the rear inclined portion 19 in the flocked portion 7 is pressed against the inside of the tooth 33 in the lower dental arch row.
