A coaxial filter cigarette with a rod portion having an inner core of material glowing substantially free of residue, in particular tobacco material, a sheath or wrapper for the inner core, an outer shell of tobacco and/or non-tobacco material coaxially surrounding the inner core or its sheath, respectively, a sheath or wrapper for the outer shell, and with a filter portion having a filter core, an air-impermeable sheath or wrapper for the filter core, a filter shell and a sheath or wrapper for the filter shell comprises a zone of the main heat source which is located in the inner core of the rod portion and a zone in which the major part of the aerosol reaching the mouth of the smoker is produced and which is located in the outer shell of the rod portion; the filter portion greatly reduces the combustion gases originating from the inner core of the rod portion and substantially reduces the smoke particles originating from the inner core, whereas the aerosol produced in the outer shell of the rod portion is influenced only slightly or not at all.

Coaxial filter cigarette

The invention described here relates to a smokable article which is intended to enable the smoker to avoid the condensates usually present in the smoke while retaining or even enhancing the taste experience familiar from conventional cigarettes or smokable articles; this is achieved by the advantageous geometrical and thermodynamic configuration of the heat source.

Smokable article

A coaxial cigarette comprising an inner core of a material glowing away substantially without residue, in particular tobacco material, with a sheath for the inner core, an outer jacket coaxially surrounding the inner core and its sheath and comprising a tobacco and/or non-tobacco material, and a sheath for the outer jacket, has a diameter of the inner core which lies in the range from 45% to 80% of the outer diameter of the coaxial cigarette; the inner core has a packing density in the range from 300 to 400 mg/cm.sup.3 ; the outer jacket has a packing density in the rnage from 170 to 250 mg/cm.sup.3. The sheath of the inner core has an air permeability of less than 3 ISO units. The outer sheath has a front segment to be lit and a rear mouth-side segment; the front ignition-side segment of the outer sheath contains conventional glow salts and has an air permeability of 15 to 40 ISO units and the rear mouth-side segment of the outer sheath contains no glow salts and has an air permeability of less than 3 ISO units.
