A toothbrush head (14) is provided with a plurality of separate cleaning areas. The distal end and the proximal end of the head (14) include cleaning elements (18) mounted to generally non-movable bases (16, 20). The central portion of the head includes resilient pods (22, 24) carrying cleaning elements (26) in such a manner that the cleaning elements (26) are capable of bending away from their initial position and then returning to their initial position. In another aspect of the invention the pods are made as a separate unitary subassembly (23) wherein the cleaning elements are bristles (26A) in an IMT procedure. The unitary subassembly (23) is secured to the remainder of the cleaning head (14A) of the brush (10A) during the molding operation of the remainder of the head (14A) and the handle (12A). In this aspect of the invention non-movable bases may be provided or may be omitted.

L'invention concerne une tête de brosse à dents (14) dotée d'une pluralité de zones de nettoyage séparées. L'extrémité distale et l'extrémité proximale de la tête (14) comprennent des éléments de nettoyage (18) montés sur des bases généralement immobiles (16, 20). La partie centrale de la tête comprend des coques (22, 24) portant des éléments de nettoyage (26) de manière que ces éléments de nettoyage (26) puissent se courber loin de leur position initiale puis reprendre leur position initiale. Dans un autre aspect de l'invention, les coques sont conçues en tant que sous-ensemble unitaire séparé (23), les éléments de nettoyage étant des poils (26A) dans une procédure IMT. Ce sous-ensemble unitaire (23) est fixé au reste de la tête de nettoyage (14A) de la brosse (10A) au cours de l'opération de moulage du reste de la tête (14A) et du manche (12A). Dans cet aspect, l'invention peut comprendre ou non des bases immobiles.
