Abstract

Smoking articles are disclosed herein. In one aspect, a smoking article includes a heat source configured to generate heat upon ignition thereof, a first substrate material having an aerosol precursor composition associated therewith and a first end being fixedly engaged with the heat source, and an aerosol delivery component having opposed first and second ends, the first end of the aerosol delivery component being engaged with the second end of the first substrate material. In some aspects, the aerosol delivery component includes a second substrate material having the aerosol precursor composition associated therewith and being disposed about the first end of the aerosol delivery component and a tobacco material disposed between the second substrate material and the mouthpiece, the aerosol precursor composition associated with the first and second substrate materials being configured to produce an aerosol in response to the heat generated by the ignited heat source.

Claims20

Dependent claims

A smoking article comprising:

a power source having opposed first and second ends defining an axis extending therethrough;
a heat source in communication with the second end of the power source and extending along the axis, the heat source being configured to generate heat in response to power received from the power source;
a tubular casing having a first end engaged with the second end of the power source and extending axially about the heat source to a second end;
a solid tobacco material housed within the tubular casing, the solid tobacco material being configured as a cylindrical tube extending about a circumferential surface of the axially-extending heat source, between the heat source and the tubular casing and the solid tobacco material being configured to produce an aerosol in response to the heat generated by the heat source;
and
a mouthpiece defined by the second end of the tubular casing, opposite the cylindrical tube of the solid tobacco material from the power source, the mouthpiece being configured to receive the aerosol from the solid tobacco material in response to a draw applied to the mouthpiece.
