CA 2499552

A toothbrush (10) having a handle (12) and a head (14) secured to the handle includes a gripping section (18) on the handle. A through hole (20) is formed completely through the gripping section from one outer gripping surface to the other. The through hole contains a yieldable material (22) which is preferably a soft elastomeric mass which shifts in response to the application of force. The yieldable material may be air within an air pocket (38) in the through hole where the through hole is covered by thin skins. The yieldable material may be a low hardness elastomer which is adhered to a higher hardness elastomer (64) in the through hole with the higher hardness elastomer adhered to the rigid or semi-rigid handle material (62).

Cette invention concerne une brosse à dents avec tête et manche dont le manche présente une zone de préhension. La zone de préhension est constituée par un trou traversant allant d'une surface de préhension à une autre surface de préhension. Ce trou traversant comprend un matériau déformable constitué de préférence par une masse élastomère tendre qui plie lorsqu'on lui applique une force. Ce matériau déformable peut être constitué par une poche d'aire remplissant le trou traversant et recouverte de minces membranes. Le matériau déformable peut être également constitué par un élastomère tendre collé à un élastomère plus dur dans le trou traversant, cet élastomère plus dur étant lui-même collé au matériau du manche rigide ou semi-rigide.
