Title (EN) TOOTHBRUSH, TOOTHBRUSH FILAMENT AND METHOD FOR MANUFACTURING SAME
(FR) BROSSE À DENTS, FILAMENT DE BROSSE À DENTS ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)The present invention relates to a toothbrush. The invention relates in particular to a toothbrush filament having a filament body surrounding a matrix material in which grains are embedded, wherein the matrix material and the grains have a different resistance to etching so that by etching the matrix material and/or the grains a surface structure can be created on the filament body at least in the area of the tapering end section. According to one aspect of the present invention, grains having a shell structure with a grain shell, in which is encapsulated a grain core comprising a core material different from the shell material, have been embedded in the matrix material of the filament.
(FR)L'invention porte sur une brosse à dents et en particulier sur un filament de brosse à dents dont le corps entoure un matériau matrice dans lequel des grains sont incorporés, le matériau matrice et les grains ayant une résistance différente à l'attaque acide de manière que l'attaque du matériau matrice et/ou des grains génère une structure superficielle sur le corps du filament au moins dans la section effilée de son extrémité. Selon un aspect de l'invention, les grains présentant une structure à coque dans laquelle est encapsulé le noyau du grain dont le matériau diffère du matériau de la coque, ont été noyés dans le matériau matrice du filament.
