Abstract

L'invention concerne une brosse à dents (10) à deux têtes comprenant un manche allongé (12L, 12R) pourvu de deux cols allongés (13L, 14R) partant d'une extrémité dudit manche. Un support de poils se trouve au niveau d'une extrémité distale de chacun des deux cols allongés. Une pluralité de poils (5) se dressent sur chacun des deux supports de poils, lesdits supports étant sensiblement parallèles l'un par rapport à l'autre. Le manche allongé et les deux cols allongés sont constitués par un matériau présentant une souplesse, une élasticité et un résistance à la flexion prédéterminées. Les poils présentent une rigidité prédéfinie établie en fonction desdites souplesse, élasticité et résistance à la flexion prédéterminées. Dans un autre mode de réalisation, l'invention concerne un élément de contact (16) élastique destiné au pouce: inséré dans une cavité (16C) ménagée sur le manche allongé, cet élément saillit sur le manche au niveau d'une zone de contact avec le pouce.
