Abstract (en)
[origin: EP0630587A1] The coaxial filter cigarette (100) according to the invention consists of a coaxial strand part (101) and a coaxial filter element (111). The strand part has an inner core (102) of a material which smoulders largely without residue, especially tobacco material, which is surrounded by a wrapper (103) which, in turn, is surrounded by an outer shell (104) of a tobacco and/or non-tobacco material. A wrapper (105) of an air-permeable material wraps the outer shell. The coaxial filter element (111) possesses a filter core (112) with an air-impermeable wrapper (113). The filter core or its wrapper coaxially surrounds a filter shell (114) whose diameter corresponds to the diameter of the outer shell. An air-impermeable wrapper (115), which also serves to connect the strand part and the filter element, surrounds the filter shell. A ventilation zone (116) is incorporated into the air-impermeable wrapper for the filter shell. A smoke mixing zone (120) for changing, in a defined manner, the smoke mixture leaving the strand part before it flows into the filter element is designed in the transition region between the strand part and the filter element. <IMAGE>
