Description of the Related Art Generally, a toothbrush is formed by bundling a plurality of brushes in a round hole having a diameter of about 1.5 to 2.0 mm formed on a flocked surface of a toothbrush head, and forming a small piece of metal called a flat wire. Alternatively, the hair is implanted by folding it into two pieces using a small plastic piece and driving it.

The distance between the hole and the hole is about 0.5 to 1.2 mm, and the hair is regularly planted in a substantially grid pattern. The denseness of the brush with respect to the hole area is about 0.55 to 0.60. .

先がうまくフィットしない場合があった。In the case of the above-described toothbrush in which the hair bunch is planted, the hair bunch is too large with the bristles of a normal toothbrush, and the bristles have a complicated shape in the oral cavity or the teeth. There were cases where it did not fit well.

構造が複雑になってしまうという難点がある。In the case of a toothbrush having independent brushes, the feel becomes very soft and the feeling of use is good, but on the other hand, the brushes are independent because each brush is independent. The waist is weak and may not be able to be sufficiently cleaned in practice. Furthermore, in order to implant each brush independently, it is necessary to hold the brushes independently at the time of implantation, but generally the total number of brushes implanted on the implantation surface of the toothbrush head is several hundred to several thousand. There is a drawback that the structure of the mold and the brush holding mechanism is complicated because it is a book.

８程度である。In the case of the heat fusion method or the in-mold method,
Since there is no flocked hole in the toothbrush head as in the flat wire flocking method, the bristle bundle density P is defined as follows. That is, in the case of the heat fusion method, the sum of the cross-sectional areas of the brushes forming the bristle bundle with respect to the opening cross-sectional area of the bristle bundle insertion sleeve used when the enlarged portion is thermally fused to the toothbrush head portion. In the case of the in-mold method, it is expressed by the ratio of the sum of the cross-sectional areas of the brushes constituting the hair bundle to the opening cross-sectional area of the hair bundle insertion hole of the mold. Further, as a simple method, assuming that there is a flocked hole having the bristle shape in an actual toothbrush, a virtual line (FIG. 1B) that smoothly connects the bristle circumference along the outermost brush It may be represented by the ratio of the total cross-sectional area of the brushes 2 constituting the hair bundle to the area surrounded by the dotted line in the middle). In general, the density P of bristle bundles of a toothbrush by a heat fusion method or an in-mold method is 0.64 to 0.8.
It is about 8.

い。In the same manner, the diameter D of the hair bundle 1 is assumed to have a flocked hole having the shape of the hair bundle 1 as shown by a dotted line in FIG. It can be considered as an imaginary line that smoothly connects the periphery of the hair bundle along the brush. Practically, in consideration of the gist of the present invention, when a circular hair bundle is assumed, a hair bundle diameter of about 0.25 mm to about 1.0 mm, more preferably about 0.25 mm to about 0.5 mm is good.

If the cross-sectional shape of the brush 2 is a shape other than a circle, such as a quadrangle, a triangle, or a hexagon, it is 1.0 to 0.88.
Closer, if packed further, up to 1.0 or more
It is also possible to raise. However, if the hair bundle density P is increased too much, the bristle tip is opened outward toward the tip of the brush, which is not preferable from an aesthetic point of view.

とすることがより好ましい。In consideration of the working efficiency in the steps of adjusting the shape of the hair bundle and the tip of the hair during the manufacturing process, and finally extracting and taking out the toothbrush from the mold, the density of the bristle bundle P is as described above. A range of about 0.64 to 0.88 is preferable, but a range of 0.64 to 0.75 is more preferable in consideration of a balance between manufacturing efficiency and toothbrush performance.

混在させて、植毛面５の一部に植毛する。When manufacturing the toothbrush of the present invention, the base end of the bristle bundle 1 satisfying the above conditions is melted by thermal means to form the enlarged portion 3 and the brush 2 is integrated. Then, as shown in FIG. 2, the bristle bundle 1 having the enlarged portion 3 at the base end is transplanted to the entire surface of the flocking surface 5 of the toothbrush head portion 4 by a heat fusion method or an in-mold method, or As shown in FIGS. 3 to 10, the hair is implanted on a part of the implanted surface 5 while being mixed with the hair bundle 6 of the related art having a large number of brushes.

記効果を奏することが難しくなる。By using the toothbrush having such a configuration, the feeling of use is softer than in the past, and the hair tips can reach fine portions in the oral cavity. In addition, the brushes 2 can be implanted one by one independently. Since there is no need to perform the operation, the mold and the brush holding mechanism at the time of manufacturing the toothbrush can have a simple structure. In order to exhibit these effects, A in the formula (1) needs to be in the range of 0.04 to 0.8. If it is smaller than 0.04, the number of brushes Y is too small and the hair bundle becomes too soft, and if it is larger than 0.8, the number of brushes Y is too large and the hair bundle becomes too hard, and the above effect is obtained. Is difficult to play.

が発生するため、好ましくない。As a method of manufacturing the toothbrush according to the present invention, a heat fusion method or an in-mold method is used as described above. In the case of flat-line type hair transplantation, problems such as an increase in the number of holes and difficulty in hair transplantation due to the approach of the hair bundles and hair bundles are not preferable.

Nylon 10, 12), polyester (eg, polybutylene terephthalate, polyethylene terephthalate, etc.), polypropylene, and the like can be used. Of course, a composite filament combining these may be used.

い。In general, the brush diameter is the same in one brush except for the rounded portion at the tip of the bristle, but is not limited to this. Then, it may be in the form of highly tapered hair whose diameter gradually decreases toward the tip of the hair tip. The shape of the brush tip may be a spatula shape, a scraper shape, a spherical shape, or the like.

択することが好ましい。The shape of the brush tip surface constituted by the tip of the bristle tip is not particularly limited. However, if it is a flat surface, more bristle tips and a dentifrice can uniformly act on the smooth surface of the teeth and gums. Further, if the entire shape is formed into a substantially concave shape, the effect of holding the dentifrice is improved, and it is easy to fit a complicated curved surface of the tooth, and the brushability is improved. Further, if the surface is convex or the surface is inclined as a whole, the bristle tip can efficiently reach the recessed portion where plaque tends to accumulate, such as the cervical portion and the interdental portion, and the brushing effect can be further enhanced. It is preferable that these are appropriately selected in accordance with the design purpose of the toothbrush.

Of course, there may be hair bundles having various brush diameters on one flocking surface, and may be appropriately selected in consideration of usability, brushing feeling, cleaning effect, and the like, and in some cases, combined with a conventional hair bundle.

Various shapes, such as a block bristle bundle, can be adopted, and they can also be used in combination. In addition to the combination with the conventional hair bundle,
It can also be combined with the technique of independently planting the brushes of a book.
