  • a second substantially straight line region S2 continuous to the back surface of the head portion and the second substantially straight line regions S2 to S3 are provided. 7.
  • the radius of curvature R3 of the third curved region E3 is larger than the radius of curvature R1 of the first curved region E1. It is the described toothbrush.
  • the flock holes 6 are not limited to a configuration in which a plurality of flock holes 6 are arranged side by side in a grid pattern, but may be a configuration in which a plurality of flock holes 6 are arranged in a staggered pattern. Moreover, since the inner diameter of the tufting hole 6 correlates with the number of tufts to be tufted, it affects the hardness and usability of the tufts, but the usability depends on the thickness and length of the tufts used for tufting. Although it can be adjusted to some extent, a range of 1.0 to 3.0 mm is generally preferable.
  • the cross-sectional shape of the brush is usually circular, but is not limited to such a shape.

Thereby, when cleaning the inside of the oral cavity, it is possible to reduce the stress concentration generated at the boundary (stepped portion 9) between the handle portion 3 and the neck portion 4 due to the elastic force of the covering material 8.

Abstract

L'objectif de la présente invention est de fournir une brosse à dents avec laquelle la flexion d'une partie col peut être supprimée par le corps principal de brosse global, même si une partie tête est rendue plus fine et la partie col est rendue plus étroite, et avec laquelle d'excellentes propriétés de préhension d'une partie manche et une bonne efficacité d'utilisation dans la cavité buccale peuvent être obtenues simultanément. Une brosse à dents (1) est pourvue d'un corps principal de brosse (2) comprenant une partie manche (3), une partie col (4) qui s'étend à partir d'une extrémité distale de la partie manche (3), et une partie tête (5) disposée à l'extrémité distale de la partie col (4), une pluralité de paquets de poils étant implantés dans une surface d'implantation de poils (5a) de la partie tête (5), et le corps principal de brosse (2) présentant une forme dans laquelle l'épaisseur de la partie col (4) augmente de façon continue à partir de la partie tête (5) vers la partie manche (3). Une épaisseur D1 de la partie tête (5) est de 2 à 4 mm, une épaisseur minimale D2 de la partie col (4) est de 3 à 4,5 mm, et une épaisseur maximale D3 de la partie manche (3) est de 13 à 16 mm.
