Patent

CA 2323509

The invention relates to a cleaning brush, especially a toothbrush, comprising a handle (1) and an oblong-shaped brush head consisting of a flexible bristle carrier with a longitudinal cross-section which tapers inwards from the handle to the front end of said brush head and which has bristles attached thereto. The bristle carrier has two sections (9,10) that are placed behind each other in a longitudinal direction and which are connected to each other without any transition. Said sections are made of materials with different properties. At least the front section (9) is made from an elastomer. The materials, cross- sections and flexural length of the sections are selected in such a way that the front section (9) can be diverted with a smaller radius of curvature than the other section (10).

L'invention concerne une brosse de nettoyage, notamment une brosse à dents, qui comprend un manche (1) et une tête oblongue composée d'un porte-soies flexible dont la section transversale longitudinale s'amenuise à partir du manche en direction de l'extrémité avant de la tête, et de soies fixées dessus. Le porte-soies comprend deux sections (9, 10) disposées l'une à la suite de l'autre dans son sens longitudinal et interconnectées sans transition, qui se composent de matériaux ayant différentes propriétés. Au moins la section avant (9) est en élastomère. Les matériaux, les sections transversales et la longueur de flexion élastique sont sélectionnés de manière que la section avant (9) puisse être déviée avec un rayon de courbure inférieur à celui de l'autre section (10).
