Abstract

The cigarette has a filter attached to the end of its section (T1) containing the tobacco, the filter being made in two sections (T2, T3), joined to one another and to the section with the tobacco by an outer sleeve (M1) with perforations (P). The filter section (T3) nearest the mouth has a lower resistance to draw, while the section (T2) between it and the tobacco has a higher resistance to draw. The two sections of the filter are joined together end to end with no gap between, and the portion of the filter after the perforations is surrounded by a thick porous sleeve (G1) impregnated with aromatic substances. The second portion (T3) of the filter is made from a material such as cellulose acetate and has a negligible tar retention capacity, while the first section (T2) is of paper and has a high tar retention capacity.
