Abstract

L'invention concerne un filtre de cigarette comprenant une partie sorbante ainsi qu'une partie filtrante qui est fixée à l'extrémité de la cigarette, lequel se caractérise en ce que la partie sorbante peut être fixée à l'extrémité libre de la partie filtrante de manière à entourer sa section d'extrémité tout en laissant un jour; à cette fin, la partie sorbante se présente sous forme d'une douille comportant des parois et un fond imperméable qui, du côté orienté vers la partie filtrante, comporte une tige de fixation dont l'extrémité est aiguë et comporte une courbure de fixation flexible avec une pointe à son extrémité. La longueur de la tige de fixation est inférieure à la longueur de la partie filtrante, et une partie de la cavité de la douille est remplie d'un matériau sorbant qui consiste en un tampon fait de coton ou d'ouate de coton. En outre, lorsque l'on utilise un matériau sorbant meuble ou granulaire dans la composition de la partie sorbante, ce dernier est disposé au fond de la douille et est fixé dans la cavité de la douille par le tampon fait d'ouate de coton. Ce modèle utile permet d'améliorer les caractéristiques de fabrication de la partie filtrante et de varier les capacités sélectives et discriminantes de la partie filtrante de la cigarette afin de piéger des composants toxiques de la fumée de cigarette.
