It is formed by implanting and fixing a plurality of flat wires to the flocking table by a method of driving or fusing with heat. In addition, it is known that the greater the cross-sectional area of the bristle bundle to be implanted and the higher the rigidity, the better the toothbrush has the function of scraping plaque and the like on the tooth surface. Also, flocking of bristle bundles having various cross-sectional shapes and arrangements, which has been difficult with flat wire flocking, has become feasible.

や清掃を効果的に行うことが困難になる。[0003] However, when the cross-sectional area of the bristle bundle is large, the effect of removing plaque on the tooth surface is improved, but the rigidity is increased, so that the tooth contact deteriorates and a soft feel is lost, The feeling of use is worsened, and the bristle is less likely to enter the gap between the teeth, making it impossible to brush the teeth efficiently. In addition, it is difficult to effectively remove and clean plaque on the back of the back teeth and the fissures, which are particularly difficult to clean and where caries frequently occur.

The bristle bundle group of 0 mm 2 is provided. According to this bristle bundle group, plaque can be effectively scraped off by the high rigidity bristle bundle of the outer peripheral portion, and the low rigidity bristle bundle of the central portion can be removed. The rigidity of the whole bristle bundle group is suppressed to improve the usability, and it is possible to polish the teeth so as to envelop them so that the teeth are gentle. In addition, the bristle bundle with low rigidity in the center portion is supported around the periphery by the bristle bundle with high rigidity in the outer peripheral portion and does not bend too much, and the bristle is smoothly inserted into the gap between the teeth and the boundary between teeth and gums. It allows you to get in and brush efficiently. Further, if the bristle bundle group is arranged at the longitudinal end portion of the toothbrush in the flocking table, the bristle bundle group allows the back teeth, which are difficult to clean and frequently caries, to be maintained while maintaining a good feeling of use. It becomes possible to effectively remove and clean plaque on the back and fissures.

2 has a circular cross-sectional shape with a diameter of about 1 mm, and this is a flocking table 1 as a group of, for example, 13 pieces.
The bristle bundle group 17 having the circular occupied cross section having an area of about 20 mm 2 is formed by planting the hairs 4. The bristle bundle group 17 is planted at the distal end of the flocking table 14 in the longitudinal direction X with a hair length such that the height of the distal end from the flocking table 14 is 9 to 11 mm. The bristle bundle group 17
The rigidity of the small-diameter bristle bundle 12 located at the outer peripheral portion 20 is higher than the rigidity of the small-diameter bristle bundle 12 located at the central portion 19 of the circular occupied cross section. That is, the small-diameter bristle bundle 12 in the central portion 19 is 0.15
The rigidity is minimized by bundling the thin bristles 11 having a thickness of about 0.2 mm, while the bristles 11 of the outer peripheral portion 20 are binding the bristles 11 having a thickness of about 0.23 mm. With this configuration, the rigidity is the highest. Then, the small-diameter bristle bundle 1 of the intermediate portion 21 located therebetween.
By making the thickness of the bristles 11 constituting about 2 about 0.2 mm, the bristles bundle 12 having a small diameter
Has a stiffness that gradually increases.

The height of the tip end of the small-diameter bristle bundle 12 located at is higher. That is, the small-diameter bristle bundle 12 at the center portion 19 has the lowest tip height from the flocking table 14 of about 9 mm, while the small-diameter bristle bundle 12 at the outer peripheral portion 20 has a tip height from the flocking table 14 of 11 mm. The tip height of the small-diameter bristle bundle 12 located at the intermediate portion 21 therebetween is set to about 10 mm, and the tip height of the small-diameter bristle bundle 12 gradually increases outward. I am trying to become. By changing the height of the distal end of the small-diameter bristle bundle 12 constituting the bristle bundle group 17 so as to increase toward the outside in this manner, it is difficult to clean the small-diameter bristle bundle 12 and to reduce the depth of the posterior teeth, which are caries-prone parts. Removal and cleaning of plaque can be performed more effectively.

Can be lower. By changing the height of the tip end of the small-diameter bristle bundle 12 so as to decrease toward the outside in this manner, removal and cleaning of plaque on the fissures of the posterior teeth, which are difficult to clean and where caries are frequently caused, are performed. Can be performed more effectively.

That is, the toothbrush 10 of the present embodiment has a central portion 19.
The outer peripheral portion 20 is smaller than the small-diameter bristle bundle 12
Is provided with a bristle bundle group 17 having an occupied cross-sectional area of 20 mm 2 , the rigidity of which increases as the small-diameter bristle bundle 12 located in the small-diameter bristle bundle 12 increases. The plaque can be effectively scraped off, and the small-diameter bristle bundle 12 having a low rigidity in the central portion 19 suppresses the overall rigidity of the bristle bundle group 17 to improve the feeling of use and also wrap the teeth. Makes it possible to polish and soften the teeth. Further, the small-diameter bristle bundle 12 having a low rigidity of the central portion 19 is supported around the small-diameter bristle bundle 12 having a high rigidity of the outer peripheral portion 20 and does not bend too much.
Efficient brushing can be performed by smoothly entering the gap between the teeth and the gap between the teeth and the gums.

That is, the toothbrush 10 of the present embodiment is
Since the bristle bundle group 17 is arranged at the tip end in the longitudinal direction X of the toothbrush 10 in the flocking table 14 that contributes to brushing of the back teeth, the bristle bundle group 17 maintains the back of the back teeth while maintaining a good usability. It is possible to easily improve the plaque removal efficiency and cleaning efficiency for the crevices and fissures.
