CA 2331186

A toothbrush enhanced in a portions-between-teeth cleaning performance without sacrifice in a smooth-surface cleaning performance; specifically a toothbrush which is capable of, as its main theme, enhancing a portions-between-teeth cleaning performance and providing durability for maintaining the performance and which is, as its sub-theme, excellent in appearance and durability. To attain the main theme, tuft holes formed in a block head are in an approximately oval or rectangular shape, the tuft holes are inclined with respect to the block head surface and mono-filaments in rectangular cross section are used to increase a cleaning performance. To attain the sub-theme, a method of driving parallel lines are disclosed such that adjacent tuft holes are staggered with each other so that the driven parallel lines do not lie on a linear line.

L'invention porte sur une brosse à dents dont on a amélioré les propriétés de nettoyage des parties entre les dents sans porter préjudice aux propriétés de nettoyage des surfaces lisses. Dans un premier aspect, l'invention porte spécifiquement sur une brosse à dents destinée à améliorer les propriétés de nettoyage des parties entre les dents et dont la solidité permet de conserver ces propriétés, et dans un second aspect, sur l'excellente esthétique et solidité de la brosse. Dans la réalisation du premier aspect, les trous accueillant les touffes de poils formés dans une tête bloc sont de forme ovale ou rectangulaire, approximativement, et des monofilaments de section rectangulaire sont utilisés pour améliorer les propriétés de brossage. Dans la réalisation du second aspect, on fait appel à un procédé permettant de tracer des lignes parallèles de sorte que les trous accueillant les touffes soient décalés afin que ces lignes parallèles ne reposent pas sur une ligne linéaire.
