ABSTRACT:
The invention relates to a segmented filter cigarette comprising a tobacco rod including at least two segments of differing tobacco fillings, a wrapping for said tobacco rod, and a filter, said at least two segments of said tobacco rod having a coaxial structure, each comprising an inner core of tobacco material, a wrapping for said inner core, a jacket of a different tobacco material and a wrapping for said jacket; the tobaccos of said inner cores of said segments have the same or a very similar condensate potential; the tobaccos of said jackets of said segments have the same or a very similar condensate potential which differs, however, from the condensate potential of said inner cores; by defining the resistances to draw of said inner cores and of said jackets of said segments and by adapting said filter it is achieved that the smoke is drawn substantially from the region having a high condensate potential of the first-burning segment during smoking of the segmented filter cigarette, and the smoke is drawn substantially from the region of said segment having the lower condensate potential during smoking of the filter-end segment to achieve the same perception of taste puff-for-puff. By specially designing the coaxial filter an increasing proportion of smoke is introduced into the filter part having high filtering effectiveness during smoking of said first segment.
