Embodiment Construction

[0260] exist figure 1 A smoking article 2 according to a first embodiment of the invention shown in , comprises a closed combustible heat source 4, an aerosol-forming substrate 10, a transfer element 12, an aerosol cooling element 14, a spacer element 16 and Mouthpiece 18 , the enclosed combustible heat source 4 has a front face 6 and an opposite rear face 8 .

[0261] The blind combustible heat source 4 is a blind carbonaceous combustible heat source and is located at the distal end of the smoking article 2 . Such as figure 1 As shown in , a non-flammable substantially air-impermeable barrier 22 in the form of a disc of aluminum foil is disposed between the rear face 8 of the enclosed combustible heat source 4 and the aerosol-forming substrate 10 . The barrier 22 is applied to the back face 8 of the blind combustible heat source 4 and abuts the back face 8 of the combustible carbonaceous heat source 4 and the aerosol-forming substrate 10 by pressing a disc of aluminum foil ...

Abstract

A smoking article (2, 44, 50) comprises: a combustible heat source (4) having opposed front (6) and rear (8) faces; an aerosol-forming substrate (10) downstream of the rear face (8) of the combustible heat source (4); a first heat-conducting element (36) comprising one or more radially inner layers of heat-conductive material overlying a rear portion of the combustible heat source (4); and a second heat-conducting element (38, 64) comprising one or more radially outer layers of heat-conductive material overlying at least a portion of the aerosol-forming substrate (10), 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.

Description

technical field [0001] The present invention relates to smoking articles comprising a combustible heat source having opposing front and rear faces, an aerosol-forming substrate downstream of the rear face of the combustible heat source, and a non-overlapping, radially separated, dual heat transfer element. Background technique [0002] Various smoking articles have been proposed in the art in which the tobacco is heated rather than combusted. One object of such 'heated' smoking articles is to reduce known types of noxious smoke constituents produced by the combustion and thermal degradation of tobacco in conventional cigarettes. In one known type of heated smoking article, an aerosol is generated by heat transfer from a combustible heat source to an aerosol-forming substrate. The aerosol-forming substrate can be located within, around, or downstream of the combustible heat source. During smoking, volatile compounds are released from the aerosol-forming substrate by heat tr...
