Embodiment Construction

[0120] according to figure 1 The smoking article 100 of the first embodiment of the invention shown in FIG. 2 comprises a contiguous, coaxially aligned combustible carbonaceous heat source 102 , an aerosol-forming substrate 104 , an airflow directing element 106 , an aerosol cooling element 108 and a mouthpiece 110 . The combustible carbonaceous heat source 102, aerosol-forming substrate 104 and airflow directing element 106 are overwrapped with a first outer wrapping material 112 of cigarette paper having low air permeability to form a first section 114 of the smoking article 100. The aerosol cooling element 108 and the mouthpiece 110 are wrapped with a second outer wrapper 116 of cigarette paper having low air permeability, thereby forming a second section 118 of the smoking article 100 . The first section 114 is thus upstream of the second section 118 . The smoking article 100 further comprises a bundle of tipping papers 120 surrounding at least a downstream part of the fi...

Abstract

The present invention relates to an aerosol generating article (100) having a first section (114) including a combustible heat source (102) and an aerosol-forming substrate(104) and a second section (118) including a tubular element (150) defining a recess (152) at one end of the second section(118). The first and second sections (114, 118) are integrally connected at a region of weakness(122) andare separable at the region of weakness. This enables the tubular element (150) to be placed over the combustible heat source(102), after use of the aerosol generating article, such that the combustible heat source is at least partially received in the recess (152) to reduce the ignition propensity of the smoking article. The first section is upstream of the second section when the first and second sections are integrally connected and the tubular element is at least partially open at both of its ends such that air may be drawn through the tubular element. The tubular element is either at thedownstream end of the second section such that the recess forms a mouth end cavity, or is at the upstream end such that the recess forms a transfer element.

Description

technical field [0001] The present invention relates to an aerosol-generating article, such as an aerosol-generating article, having a combustible heat source for heating an aerosol-forming substrate downstream of the combustible heat source. Background technique [0002] Various smoking articles in which tobacco is heated rather than combusted have been proposed in the art. One aim of such 'heated' smoking articles is to reduce known noxious smoke constituents in conventional cigarettes produced by the combustion and pyrolytic degradation of tobacco. In one known type of heated smoking article, an aerosol is generated by transferring heat from a combustible heat source to a physically separate aerosol-forming substrate, such as tobacco. The aerosol-forming substrate can be located within, around, or downstream of the combustible heat source. For example, WO-A2-2009 / 022232 discloses a smoking article comprising a combustible heat source, an aerosol-forming substrate downst...
