Abstract

La présente invention concerne une tête de brosse à dents munie d'un support de poils sur lequel est disposée une touffe de poils qui présente une pluralité de filaments, au moins un filament présentant un rétrécissement en direction de son extrémité libre, ainsi qu'une brosse à dents équipée d'une telle tête de brosse à dents. Il est proposé de donner au rétrécissement à la pointe dudit ou desdits filaments une forme différente d'une symétrie rotationnelle afin de conserver dans une direction une rigidité à la flexion élevée du filament. Conformément à l'invention, le rétrécissement est réalisé sous la forme d'un affûtage comprimé à plat de sorte que le filament, dans la zone du rétrécissement, présente par rapport à un premier axe transversal une rigidité à la flexion plus élevée que par rapport à un deuxième axe transversal perpendiculaire à celui-ci. La section transversale du filament dans la zone de l'affûtage comprimé à plat possède un axe longitudinal ou un long axe principal ainsi qu'un axe transversal plus court ou un axe principal court, ce qui a pour effet que le filament reçoit dans la zone de l'affûtage des moments d'inertie géométrique différents par rapport aux deux axes mentionnés. L'affûtage comprimé à plat à la pointe du filament facilite la pénétration dans les espaces entre les dents, le moment d'inertie géométrique plus élevé du côté plus large empêchant ici la flexion.
