摘要:
A filter cigatette comprises a tobacco rod having a tobacco mixture with a low packing or filling density, a first filter element racing the tobacco rod, having a retention capacity of 40 to 80% and consisting of a fibrous material having a low single denier and a high total denier, a second filter element facing the mouth of the smoker and having a retention capacity of 15% at the maximum, and a hollow chamber formed between the two filter elements and having a length of 3 to 7 mm at an overall length of the filter between 18 and 30 mm. The two filter elements and the hollow chamber are surrounded by a paper wrapper and an air-permeable tipping paper with a ventilation zone in the region of the hollow chamber; said ventilation zone ensures a ventilation degree of 50 to 85% and is created on the finished cigarette by laser beams or by mechanically produced perforations through both papers.In this way a more intensive taste sensation can be achieved together with a low nicotine to condensate ratio.
