Abstract

PROBLEM TO BE SOLVED: To provide a toothbrush capable of helping usefully and satisfactorily disposing toothpaste onto the tooth faces under retaining the toothpaste in a recess in the middle and of efficiently cleaning the whole of the tooth faces of the tooth parts, molar engaging faces, tooth necks, incisors and molars in the use of the toothbrush with the toothpaste.SOLUTION: A toothbrush body 1 includes a filling part 2 and a holding part 3. In the bristle of the bristle-implanting part 2, the length thereof is longer in the bundle 4 provided on the outer peripheral part and is shorter in the bundle 5 provided on the inside part to form the recess 6 for retaining the toothpaste in the middle.

Description

本発明は、歯磨剤を歯ブラシにつけて用いるに当たり、歯磨剤を保持した状態で歯面に無駄なく行き渡らせるために、歯間部、臼歯咬合面、歯頸部及び前歯、臼歯の歯面全体の掃除を効果的に行うことができる歯ブラシに関する。   The present invention uses a dentifrice attached to a toothbrush, and in order to spread the tooth surface without waste while holding the dentifrice, the interdental portion, molar occlusal surface, cervical and anterior teeth, and the entire tooth surface of the molar tooth. The present invention relates to a toothbrush that can be effectively cleaned.

歯ブラシは、周知のようにハンドル(把持部)と一体のヘッド(植毛部)に植毛部を形成し、この植毛部に刷毛を植毛する。このような歯ブラシは通常、刷毛を等しい長さ(長さ)に切断して複数の毛束を植毛部に等間隔で配置している。
なし
As is well known, the toothbrush forms a flocked portion on a head (flocked portion) integrated with a handle (gripping portion) and implants a brush on the flocked portion. Such a toothbrush usually cuts the brush into equal lengths (lengths) and arranges a plurality of hair bundles at equal intervals on the flocked portion.
None

上述した従来の歯ブラシは、各毛束の高さが等しいため、歯磨剤が歯ブラシからこぼれ落ちやすく、歯磨き中に歯磨剤が充分全体に行き渡らないで、効果的に清掃ができない問題があった。ここで本発明は可及的に歯磨剤がついた歯ブラシの状態を保ち、効果的に清掃ができる歯ブラシを提供することを目的とするものである。   In the conventional toothbrush described above, the height of each bristles is the same, so that the dentifrice easily spills from the toothbrush, and the dentifrice does not spread over the whole during the toothbrushing, so that there is a problem that it cannot be effectively cleaned. An object of the present invention is to provide a toothbrush that can be effectively cleaned while maintaining the state of a toothbrush with a dentifrice as much as possible.

本発明の請求項1に記載の歯ブラシは、植毛部と把持部とからなる歯ブラシ本体において、前記植毛部の刷毛のうち、刷毛の長さを外周部分の毛束で長く内側部分の毛束で短く形成することにより、中央部に歯磨剤を保持できる凹部を構成することができるようにした。   The toothbrush according to claim 1 of the present invention is a toothbrush body composed of a flocked portion and a gripping portion, and among the brushes of the flocked portion, the length of the brush is longer by the bunch of the outer peripheral portion and the bunch of the inner portion. By forming it short, a concave portion capable of holding the dentifrice can be formed in the central portion.

本発明の請求項2は、請求項1に記載の歯ブラシにおいて、前記植毛部が長く形成される外周部分の毛束の刷毛の長さを1列ないし数列としてなる。   According to a second aspect of the present invention, in the toothbrush according to the first aspect, the lengths of the bristles of the outer peripheral portion where the flocked portion is formed long are one or several rows.

本発明の請求項3は、請求項1又は請求項2に記載の歯ブラシにおいて、前記外周部分の毛束の刷毛の長さを外側から内側に向けて徐々に短くしてなる。   Claim 3 of the present invention is the toothbrush according to claim 1 or 2, wherein the length of the bristles of the outer peripheral portion is gradually shortened from the outside to the inside.

本発明に係る歯ブラシは、刷毛の上面中央部に凹部が形成され、歯磨剤をこの凹部に入れると歯磨きに際して歯磨剤を保持でき、また外周部分が突出して外部に広がりやすく、この広がった先端凸部を歯間や歯頸部に差し込んで効果的に清掃を行うことができる。   The toothbrush according to the present invention has a recess formed in the central portion of the upper surface of the brush, and when the dentifrice is put into this recess, the dentifrice can be retained during brushing, and the outer peripheral portion protrudes easily and spreads outward. The part can be inserted between the teeth or the neck of the tooth and can be effectively cleaned.

添付図面中、図1ないし図3は本発明の歯ブラシの単純化した図であって、図1は平面図、図2は図1のA―Aに沿う断面図、図3は図1のB―B線に沿う断面図、図4及び図5は歯磨剤を本発明の歯ブラシに挿入した状態の模式図であって、図4は側断面図、図5は端面側の断面図、図6及び図7は植毛の状態の変形を示す断面図、図8ないし図12は歯と本発明歯ブラシとの使用状態の模式図である。   In the accompanying drawings, FIGS. 1 to 3 are simplified views of the toothbrush of the present invention, FIG. 1 is a plan view, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. Sectional view along line B, FIGS. 4 and 5 are schematic views of a state where the dentifrice is inserted into the toothbrush of the present invention, FIG. 4 is a sectional side view, FIG. 5 is a sectional view on the end face side, FIG. 7 and FIG. 7 are cross-sectional views showing the deformation of the flocked state, and FIGS. 8 to 12 are schematic views of the use state of the tooth and the toothbrush of the present invention.

先ず,図1ないし図3において、歯ブラシ本体1は植毛部2と把持部3とからなり、植毛部2では、刷毛の長さを外周部分では毛束4を長く、内側部分では毛束5を短く形成することにより、中央部に凹部6を構成するのである。なお、外周部分の毛束4の刷毛の長さは数列とする。前記凹部6に図4及び図5に示すようにペースト状、ジェル状などの歯磨剤7を挿入することによって、歯磨剤7を確実に凹部6内に保持することができるのである。   First, in FIG. 1 to FIG. 3, the toothbrush body 1 is composed of a flocked portion 2 and a gripping portion 3. In the flocked portion 2, the length of the brush is long at the outer peripheral portion and the bristles 5 are long at the inner portion. By forming it short, the recess 6 is formed in the central portion. Note that the length of the brush of the hair bundle 4 at the outer peripheral portion is set to a few rows. As shown in FIGS. 4 and 5, the dentifrice 7 can be securely held in the recess 6 by inserting a paste or gel dentifrice 7 as shown in FIGS. 4 and 5.

変形として、図6及び図7に示すように、外周部分の毛束4の長さを、外側から内側に向けて徐々に短く形成することも考慮される。これによって、歯に対する毛束の当たりをよりシャープにすることができるものと考えられる。   As a modification, as shown in FIGS. 6 and 7, it is considered that the length of the hair bundle 4 in the outer peripheral portion is gradually shortened from the outside toward the inside. Thus, it is considered that the contact of the hair bundle with the teeth can be made sharper.

図8ないし図12は、歯に対する本発明歯ブラシの使用状態を示す模式図であって、図8は刷毛の凹形部分を咬合面に垂直に当てることによって、臼歯咬合面の小か裂溝の清掃が効果的にできる。図9は外側の刷毛の毛束を歯軸に対して30°〜45°にして歯肉溝に軽く挿入することで外側の刷毛の毛束を歯肉溝(ポケット)内を効果的に清掃する。   FIG. 8 to FIG. 12 are schematic views showing the use state of the toothbrush of the present invention with respect to teeth, and FIG. 8 shows the small clefts of the molar occlusal surface by applying the concave part of the brush perpendicular to the occlusal surface. Cleaning can be done effectively. FIG. 9 effectively cleans the outer brush bundle in the gingival crevice (pocket) by gently inserting the outer brush bundle in the gingival sulcus at 30 ° to 45 ° with respect to the tooth axis.

図10及び図11は、中央の短い刷毛を舌側及び唇側に使うと効率よく清掃ができる。図12は舌側及び唇側歯頸部を外側の長い刷毛の毛束を使用することで効率よく清掃ができる状態の二例を示すものである。   10 and 11, efficient cleaning can be achieved by using a short central brush on the lingual side and the lip side. FIG. 12 shows two examples of a state where the lingual and labial tooth neck portions can be efficiently cleaned by using a long bundle of brushes on the outside.
