ABSTRACT:
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.
