The invention relates to a coaxial tobacco cartridge with an inner core of a first tobacco blend, a sheath for the inner core, an outer jacket of a second tobacco blend, a sheath of high air permeability and an associated filter element. The coaxial tobacco cartridge is not smokable independently, but can be used by persons to make their own coaxial cigarettes, by inserting it in an appropriate cigarette-paper tube or wrapping it in a cigarette-paper strip.

Tobacco cartridge

A smokable article having an aerosol generating zone connected to a mouthpiece via a tubular intermediate zone, wherein the aerosol generating zone includes an annular combustion element and a cylindrical carrier for an aerosol precursor coaxially disposed therewithin with a space therebetween forming air flow passages. Heat from the combustion element conducted to the aerosol carrier generates aerosols that may be drawn by air passing through the air flow passages to the mouthpiece by a smoker.

Smokable article

The present invention relates to a smokable article which is intended to permit the smoker to avoid the condensates usually present in the smoke while retaining the taste experience familiar from conventional cigarettes; this is achieved in that a sheet-like carrier element coated with an aroma-carrying material and having a low thermal capacity is brought into direct thermal contact with a heat source comprising a hollow cylindrical combustion element having at least one passage therethrough wherein said passage is separate and distinct from the hollow portion; in the pauses between draws a cavity serves as collecting container or reservoir for the aromatic substances developed which can be inhaled in the next draw by the smoker.

A smokable article including an aerosol generating zone which has a combustion element and a carrier for an aerosol precursor which coaxially surrounds the combustion element, flow passages in the aerosol generating zone and a mouthpiece. The combustion element includes axial flow passages extending over its entire length and a jacket formed of a gas-impermeable heat-insulating material. The jacket is surrounded at a distance by a concentric sleeve of a gas-impermeable material so that between the jacket and the sleeve at least one flow space results; the sucked-in air flows through the flow passages in the combustion element, then back through the flow space between the jacket and the sleeve and finally through the carrier for the aerosol precursor to the mouthpiece. The carrier includes a precursor, and the combustion element has a plurality of axial passages.

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.
