Patent

CA 2735548

The present invention is directed to a toothbrush having a handle portion, a neck portion and a head (1), said head (1) being provided with bristle tufts (6) arranged in a complex internal geometry by means of the stapling technique. To enable a visually flawless molding to be produced, material cross-sections in the head (1), in particular in the area of the blind-end holes (11, 12) provided for tufting, are taken into consideration.

La présente invention concerne une brosse à dent comportant une partie manche, un étranglement et une tête, ladite tête étant recouverte de touffes de poils disposées selon une géométrie interne complexe par une technique d'implantation par ancrage. Pour obtenir un article moulé ne présentant pas de défaut visible à l'il nu, on prend en considération des coupes transversales du matériau formant la tête, en particulier dans la zone des trous aveugles utilisés pour la mise en place des touffes de poil.
