(FR) FILTRE DE CIGARETTE
Abstract: front page image
(EN)A cigarette filter for smoking, capable of efficiently removing gas/vapor phase components in cigarette smoke, and comprising an activated charcoal and a molded activated charcoal (10) having a molding binder, wherein grooves (12) extending along the longitudinal direction of the filter are formed in the outer peripheral surface of the molded activated charcoal.

Ce filtre comprend un charbon de bois activé et un charbon de bois activé moulé (10) contenant un liant de moulage. Des cannelures (12) s'étendant dans le sens longitudinal du filtre sont formées dans la surface périphérique externe du charbon de bois activé moulé. Ce filtre de cigarette est préférable aux filtres à structure triple utilisés dans les produits à faible teneur en goudrons.
