Patent

CA 2277918

The invention relates to an oral hygiene appliance with a resilient-elastic, plastic foam - like working piece on the head of a holding piece. The aim of the invention is to avoid possible penetration by cohesing or adhesion inside the foamed material by undesired bacteria, viruses and dirt particles, as is the case in hitherto known teeth cleaning appliances with elastic foamed materials. This aim is achieved in that the working piece consists of a stamping made of closed-cell foamed material (A), for example EVA-mixed polymer foamed material, whereby the cells (B) on the wall of the stamped hole are opened by the stamping.

L'invention a pour objet un appareil pour l'hygiène buccale présentant un élément de travail élastique, du type mousse, et a pour but d'éviter la pénétration, par suite des forces d'adhérence et de cohésion, des bactéries indésirables, des virus et des particules de crasse à l'intérieur de la mousse, comme cela se produit avec les mousses élastiques, dans les appareils de nettoyage dentaires connus. A cet effet, l'invention est caractérisée en ce que l'élément de travail est constitué par une pièce estampée fabriquée en une mousse à cellules fermées (A), par exemple en un produit mousse à base d'un polymère mixte EVA, les cellules (B) se trouvant à la surface estampée (Q) étant ouvertes par estampage.
