CA 2503710
A toothbrush (10) with a flexible head (14) is disclosed. At least the head (14) of the toothbrush (10) may be manufactured by in-molded technology. A blend of thermoplastic elastomer and polypropylene is used to impart added flexibility to the head (14). That flexibility is further enhanced by the tapered profile of the head (14). Cleaning elements (20) may be secured in place during manufacture using in-molded techniques or staples (26).
L'invention concerne une brosse à dents comportant une tête flexible. Au moins la tête de cette brosse à dents peut être fabriquée par une technologie dite dans le moule. L'utilisation d'un mélange d'élastomère thermoplastique et de polypropylène confère à la tête davantage de flexibilité. Le profil effilé de la tête accroît davantage la flexibilité de celle-ci. Des éléments de nettoyage peuvent être fixés en place pendant la fabrication à l'aide de techniques dites dans le moule ou d'agrafes.
