CA 2672740

A toothbrush includes a handle and a head mounted to the handle. The head may generally include a membrane attached to it and configured for attachment to a cleaning element. The membrane may be generally dome shaped and may be resiliently flexible when a brushing force is applied. A plurality of cleaning elements is mounted to the membrane. The cleaning elements may be attached using anchor free tufting. In addition, the cleaning elements may be sufficiently spaced so as to allow separation of the melted portion of the cleaning elements. In another arrangement, the head may also include walls or dams positioned between the cleaning elements. The walls prevent the melted portion of the cleaning elements from merging with the melted portion of another cleaning element. This isolation of the molten nylon allows the cleaning elements to move independently of each other.

L'invention concerne une brosse à dents qui comprend un manche et une tête montée sur le manche. La tête peut généralement comprendre une membrane qui lui est attachée et qui est conçue pour être attachée à un élément de nettoyage. En général, la membrane peut être en forme de dome et réagir de manière souple et élastique à l'application d'une force de brossage. Une pluralité d'éléments de nettoyage sont montés sur la membrane. Les éléments de nettoyage peuvent être attachés par touffetage sans ancrage. Les éléments de nettoyage peuvent en outre être suffisamment espacés pour que les parties fondues des éléments de nettoyage soient séparées les unes des autres. Dans un autre mode de réalisation, la tête peut également comprendre des parois ou des barrages disposés entre les éléments de nettoyage. Les parois empêchent la partie fondue des éléments de nettoyage de fusionner avec la partie fondue d'un autre élément de nettoyage. L'isolement du nylon fondu permet aux éléments de nettoyage de se déplacer indépendamment les uns des autres.
