Abstract
A smoking article is provided, including a combustible heat source having opposed front and rear faces; an aerosol-forming substrate downstream of the rear face of the heat source; a first heat-conducting element including one or more radially inner layers of heat-conductive material overlying a rear portion of the combustible heat source; and a second heat-conducting element including one or more radially outer layers of heat-conductive material overlying at least a portion of the aerosol-forming substrate, such that the one or more radially outer layers of heat-conductive material do not overlie the one or more radially inner layers of heat-conductive material.
Claims19
A smoking article, comprising:
- a combustible heat source having opposed front and rear faces;
- an aerosol-forming substrate downstream of the rear face of the combustible heat source;
- a first heat-conducting element comprising one or more radially inner layers of heat-conductive material overlying a rear portion of the combustible heat source;
- and
- a second heat-conducting element comprising one or more radially outer layers of heat-conductive material overlying at least a portion of the aerosol-forming substrate,
- wherein a radial distance between a longitudinal axis of the smoking article and the one or more radially outer layers of heat-conductive material is greater than a radial distance between the longitudinal axis of the smoking article and the one or more radially inner lavers of heat-conductive material, and
- wherein the one or more radially outer layers of heat-conductive material do not overlie the one or more radially inner layers of heat-conductive material.
