CA 2479945

The head of a toothbrush includes a first tuft block having bristles and a second tuft block having bristles. The first and second tuft blocks are mounted for counter-rotational or counter-rotational oscillating movement in a direction parallel to the outer surface of the head. The toothbrush head also includes a third section having bristles extending outwardly from the head to provide an extended field of bristles to support an elongated ribbon of toothpaste and for enhanced cleaning.

Selon l'invention, la tête d'une brosse à dents comprend une première section à touffe de poils et une deuxième section à touffe de poils. Lesdites première et deuxième sections sont montées de manière à effectuer un mouvement de contre-rotation ou un mouvement de contre-rotation oscillant dans un sens parallèle à la surface extérieure de la tête. Cette tête de brosse à dents comprend également une troisième section dont les poils se prolongent vers l'extérieur à partir de la tête, d'où l'obtention d'un champ de poils étendu permettant de supporter une bande allongée de pâte dentifrice en vue d'un nettoyage amélioré.
