Abstract (en)
[origin: EP0105682A1] A filter cigarrette is provided which is adjustable to provide a wide range of air dilution and/or resistance to draw values and which comprises a tobacco rod 1, a substantially cylindrical filter plug and substantially air impermeable tipping paper 11. The filter plug comprises a first, mouth-end segment 7 and a second, axially aligned, rod-end segment 3 spaced apart from the first segment. The wrapping, which is substantially air impereable, circumscribes the first and second segments defining a substantially cylindrical void 8 therebetween which may include means for releasing varying amounts of a flavourant. The first segment is movable towards the second segment thereby compressing the plug wrap between the segments which decreases the volume of the void and increases the resistance to draw value of the cigarette. Variable air dilution may be achieved by providing at least one opening 17 in the tipping paper and at least one opening 19 in the underlying plug wrap positioned such that, as the first segment is moved axially towards the second segment, the first and second openings are moved into varying degrees of registry thereby emitting varying amounts of air to the filter.
