Patent

CA 2470198

The invention concerns a smoking article filter plug (16) for a cigarette, the filter plug being cylindrical and having a plug wrap (18), grooves (20) being impressed into the plug wrap, and a tipping paper (22) for the attachment of the filter plug to the tobacco rod (12). Some grooves are axially extending with respect to the axis of the filter plug and are open on the side of the tobacco rod and extend continuously only over a part of the length of the filter plug. All grooves are covered by a ventilated tipping paper, which allows ventilating air into the axially extending grooves only. In addition the invention concerns the use of such a filter for the reduction of the CO/tar ratio as a function of the filter ventilation.

L'invention concerne un bout-filtre (16) pour une cigarette, de forme cylindrique et présentant un papier-filtre (18), des rainures (20) formées dans le papier-filtre et un papier manchette (22) servant à relier le bout-filtre au bâtonnet de tabac (12). Certaines rainures, qui s'étendent dans l'axe du bout-filtre, sont ouvertes côté bâtonnet de tabac et s'étendent, en continu, seulement sur une partie de la longueur de ce bout-filtre. Toutes les rainures sont recouvertes par un papier manchette ventilé, qui permet à l'air de ventilation de ne pénétrer que dans les rainures s'étendant axialement. Cette invention concerne, en outre, l'utilisation d'un filtre de ce type dans la réduction du rapport CO/goudrons en tant que fonction de la ventilation du filtre.
