Abstract
Description
本発明は、日常大多数の人が使用する歯ブラシのうち、歯列の噛み合せ面と唇(表)側、舌(裏)側の3面を同時に磨くことができる歯ブラシ(以下「全歯周歯ブラシ」と云う)のうち、外側植毛束を歯ブラシ躯体の中心線側に傾けて植毛する歯ブラシに関する。 The present invention is a toothbrush (hereinafter referred to as “whole periodontal toothbrush”) that can simultaneously polish the meshing surface of the dentition and the three surfaces of the lips (front) side and the tongue (back) side among the toothbrushes used by the majority of people every day. The toothbrush in which the outer bristles are inclined toward the center line side of the toothbrush housing.
全歯周歯ブラシは、大別して、普通の歯ブラシの植毛束の中央列を短く、外側列を長く植毛したものと、植毛束を2分割又は3分割し、各植毛面を平面状に配列した状態で植毛孔を垂直に設けた歯ブラシ躯体を成型し、植毛後に各植毛基材を内側に所望の角度を傾けて結合又は固定したものがある。以下、後者の文献を挙げる。 All periodontal toothbrushes can be broadly divided into a state where the center row of the flocked bundle of a normal toothbrush is short, the flocked outer row is long, and the flocked bundle is divided into two or three, and each flocked surface is arranged in a planar shape A toothbrush housing in which the flock holes are provided vertically is molded, and after flocking, each flocked base material is bonded or fixed at a desired angle inward. Hereafter, the latter literature is mentioned.

前記2例は組立てに人手を要すること、及び植毛基材の巾が25粍以上になる等の欠点を改善するものとして、夫々2列の植毛孔を有する2面の植毛基材は、薄肉の連繋帯で連設されるように硬質熱可塑性プラスチックで1次成型し、2面の植毛面が150°乃至160°位になるような金型に固定し、植毛基材間、ネック部の空隙部を1次成型材と同質、又は相熔性のある軟質合成樹脂材料で射出成型法により充填固定する本件出願人の有する「歯列を跨いで磨く歯ブラシ」がある。(特許文献3)特許4143982 In the two examples, the two-sided flocking base material having two rows of flocking holes is thin-walled so as to improve the drawbacks such as requiring manual assembly and the width of the flocking base material being 25 mm or more. Primary molding with rigid thermoplastic plastic so that it is connected with a continuous band, fixed to a mold so that the two flocked surfaces are about 150 ° to 160 °, and the gap between the flocked base materials and the neck portion There is a “toothbrush that brushes across the dentition” of the applicant of the present application, in which the part is filled and fixed by an injection molding method with a soft synthetic resin material that is the same as or compatible with the primary molding material. (Patent Literature 3) Patent 4143882
特許文献1,2においては、歯磨き後に両植毛基材の結合部や、組立部品の陰に磨き滓が滞留したり、長時間乾かない部分があり、非衛生である。又、フィラメントの先端面で磨くことにこだわったので、植毛基材の巾は25粍以上と広く、使い方は簡明で、短時間で磨き残しなく磨けるなどメリットは多いが普及し得なかった。
特許文献3による歯ブラシをモニター使用した結果、植毛基材の巾を15粍に仕上げたが、尚従来の歯ブラシと同様、巾は10乃至12粍位が望ましく、この巾で可能な限り外側の植毛束を中心線に傾けて植毛し、植毛列の内に歯列を挟む空隙列を作り、且つ磨き残り滓が滞留しないよう、両植毛基材の結合部は出来る限り平坦であることが望ましいことが分明した。In
As a result of using the toothbrush according to
現在行われている歯ブラシの製造法は、全歯周歯ブラシを含めて総て把持部、ネック部、植毛基材部を一体として、硬質熱可塑性プラスチックの射出成型法によって躯体を製作し、その際総ての植毛孔は金型のパーテングライン(以下「PL」と表示する)に対し、ほゞ垂直に設けられる植毛用ピンを抜くことによって形成される。
現行技術では、植毛束をPLの垂直線より5°以上傾けて設けたい場合には、特許文献1、2、3のように、2つに分割した植毛基材を一平面状に並べ、垂直に植毛孔を設け、植毛後に植毛基材を角度をつけて固定するのである。The toothbrush manufacturing method currently in use is that the entire gripping part, neck part, and flocking base part, including all periodontal toothbrushes, are made into one body by the injection molding method of hard thermoplastic plastic. All the flocking holes are formed by removing flocking pins provided substantially perpendicular to the parting line (hereinafter referred to as “PL”) of the mold.
In the current technology, when the hair bundle is to be provided at an angle of 5 ° or more with respect to the vertical line of the PL, as shown in
本発明においては、上記の理由から特許文献3の機能を低下させずに、植毛基材の全幅は10乃至12粍位で、植毛面が平坦か或いはこれに近い角度で連繋する植毛基材上に外側植毛束列が夫々10°位内側に傾斜している歯ブラシが求められる。 In the present invention, without reducing the function of
現在の歯ブラシの製造工程は、把持部、ネック部、植毛基材部を一体的に熱可塑性プラスチックを射出成型法によって成型されるが、植毛孔もその際同時に形成され、一般には垂直か傾斜した植毛孔を要求される場合でも、5°位までなら金型製作は可能であるが、本発明では、外側列の植毛束の傾斜は10°を求められるので、次節で述べる方法により解決した。 In the current manufacturing process of toothbrushes, the gripping part, neck part and flocked base part are integrally molded by injection molding with thermoplastics, but flocked holes are also formed at the same time, generally vertical or inclined. Even if a flock hole is required, the mold can be manufactured up to about 5 °. However, in the present invention, the inclination of the flock of the outer row is required to be 10 °, which is solved by the method described in the next section.
従来の作業工程を改変して、まず図1、図2に示すような植毛基材を1次成型で製作し、次いで図3に示すように、スリット4を拡げる金型に装着して、該スリット及びネック部、把持部を植毛基台と同一材か相熔性のある熱可塑性プラスチックの射出成型法で2次成型した後に植毛し、目的の歯ブラシを得るか、1次成型後植毛し、植毛部が収納し得る金型を用いて2次成型する。 First, a flocked substrate as shown in FIG. 1 and FIG. 2 is manufactured by primary molding, and then attached to a mold for expanding the slit 4 as shown in FIG. Slit and neck part, gripping part is the same material as the flocked base or secondarily molded by a thermoplastic injection molding method, and then transplanted to obtain the desired toothbrush, or flocked after the first molding, Secondary molding is performed using a mold that can be housed in the flocked portion.
本発明の「歯列を挟んで磨く歯ブラシ」は、一般の歯ブラシに較べ、操作が極めて簡単で、全歯面が短時間で磨き残しなく磨け、併せて歯周ポケットの清掃や歯肉のマッサージも効果的に出来るので、口臭の防除、虫歯や歯周病の予防、治療に効果がある。 The “toothbrush brushed across the dentition” of the present invention is much easier to operate than ordinary toothbrushes, and the entire tooth surface can be polished in a short time without being left unpolished. Effectively, it is effective in controlling bad breath, preventing and treating caries and periodontal diseases.
使用法は、磨き方の指導を受けなくても判るほど簡単で、又使用中に歯列から外れにくいので、幼児や軽度の介護を要する人でも自分で使用できる。 The usage is so simple that it is easy to understand without receiving instructions from the polishing staff, and since it is difficult to come off the dentition during use, it can be used by infants and those who require mild care.
普通の歯ブラシの形は、把持部の先端に細いネック部を経て、植毛基材の巾は10乃至12粍位、長さ20乃至25粍位、厚さ5粍位が定着している。この寸法や形状を大きく変えることなく、植毛列のみを歯ブラシ躯体の中心側に10°位傾けた植毛列に歯列を挟む空隙列を設けた歯ブラシの製造可能な最良の形態を詳述する。 The shape of an ordinary toothbrush is fixed at a width of 10 to 12 mm, a length of 20 to 25 mm, and a thickness of 5 mm through a thin neck at the tip of the grip. A detailed description will be given of the best mode of manufacture of a toothbrush in which only a flocked row is inclined about 10 ° toward the center side of the toothbrush housing and a gap row is provided to sandwich the tooth row without greatly changing the size and shape.
図1は、硬質熱可塑性プラスチックの射出成型法によって、1次成型で得られる歯ブラシの植毛基材の平面図を示し、図2は、図1のA−A′断面図を示し、植毛基材1、1′は中心線上に設けたスリット4によって2分割され、連繋帯3によって可撓的に繋止されている。θ′は金型の製作上、通常技術で平面に対し傾斜させて穿孔しうる通常5°以下である角度をθ′で示し、2つの植毛面2、2′はPLの平行面より各々θ′づゝ拡げ、全植毛孔5、6はPLに垂直に設ける。 FIG. 1 shows a plan view of a flocked base material of a toothbrush obtained by primary molding by a hard thermoplastic injection molding method, and FIG. 2 shows a cross-sectional view taken along line AA ′ of FIG. 1 and 1 ′ are divided into two by a slit 4 provided on the center line, and are flexibly connected by a connecting
次いで、図3のように、両植毛面2、2′のなす角が、傾けたい角θから1次成型で利得した角θ′を引いた角度θ″をPLの平行面から減じた約170°位になる金型で、スリット4及びネック部、把持部等を1次成型と同材又は相熔性のある硬質プラスチックで2次成型する。 Next, as shown in FIG. 3, the angle between both
次いで、植毛機により、中央列に3ミル位の極細のフィラメントを露出部の長さ5乃至6粍位に植毛し、外側列に太さ5乃至7.5ミル位、一端を先端極細加工したフィラメントを露出部の長さが極細加工した側は12粍位、他端は8粍位になるように植毛すれば、全植毛束が10°位歯ブラシ躯体の中心側に傾いた植毛列の内に歯列を挟む空隙列を有する歯ブラシが量産可能に得られる。 Next, using a hair transplanter, a fine filament of about 3 mil in the center row was implanted to a length of 5 to 6 mm in the exposed portion, a thickness of about 5 to 7.5 mil in the outer row, and one end was finely processed at the tip. If the hair is planted so that the length of the exposed part of the filament is 12 mm and the other end is 8 mm, the total flock is 10 ° around the center of the toothbrush case. A toothbrush having a gap row sandwiching the row of teeth can be mass-produced.
工程順序を、1次成型後直ちに全列の植毛を述上のように行った後に、2次金型に植毛を収納できる金型を用いて2次成型を行うこともできる。 It is also possible to perform secondary molding using a mold that can store the flocking in the secondary mold after the process sequence is performed immediately after the primary molding and all rows are implanted as described above.
前段まで4列植毛の歯ブラシについて説明したが、図5以降の図面に示すように、中央に主植毛基材、両脇に副植毛基材を設け、植毛基材2個と同様の手法で3列植毛の歯列を挟んで磨く歯ブラシが得られる。効果、使用法等は4列植毛と同等である。 Although the four-row flocking toothbrush has been described up to the previous stage, as shown in FIG. 5 and subsequent drawings, a main flocking base material is provided at the center, a sub-flocking base material is provided on both sides, and the same method as two flocking base materials is used. A toothbrush that brushes across the row of flocks is obtained. The effect, usage, etc. are equivalent to 4 rows flocking.
