Heated Aerosol Generating Article with Thermal Spreading Wrap

Content Provider	The Lens
Abstract	A thermally-conductive material is used in an aerosol-generating article as a thermally-conducting flame barrier for spreading heat and mitigating against the risk of a user igniting an aerosol-forming substrate of the aerosol-generating article by applying a flame to the aerosol-generating article. The aerosol-generating article is a heated aerosol-generating article for use with an electrically-operated aerosol-generating device comprising a heating element. The aerosol-generating article comprises the aerosol-forming substrate which is radially encircled by the sheet of thermally-conductive material, the thermally-conductive material comprising aluminium foil.

Claim	Use of a thermally-conductive material in an aerosol-generating article as a thermally-conducting flame barrier for spreading heat and mitigating against the risk of a user igniting an aerosol-forming substrate of the aerosol-generating article by applying a flame to the aerosol-generating article, in which; the aerosol-generating article is a heated aerosol-generating article for use with an electrically-operated aerosol-generating device comprising a heating element, and comprises the aerosol-forming substrate radially encircled by the sheet of thermally-conductive material, the thermally-conductive material comprising aluminium foi Use of a thermally-conductive material in an aerosol-generating article according to claim 1 in which the aerosol-generating article comprises a plurality of elements, including the aerosol-forming substrate radially encircled by the sheet of thermally-conductive material, assembled within a wrapper. Use of a thermally-conductive material in an aerosol-generating article according to claim 1 or 2 in which the aerosol-generating article has a mouth end and a distal end upstream from the mouth end, and in which the aerosol-forming substrate is located at the distal end of the rod. Use of a thermally-conductive material in an aerosol-generating article according to claim 1, 2, or 3, in which the aerosol-forming substrate is formed as a rod of cut filler and is radially encircled by the sheet of thermally-conductive materia Use of a thermally-conductive material in an aerosol-generating according to any preceding claim in which the sheet of thermally-conductive material is aluminium foi Use of a thermally-conductive material in an aerosol-generating article according to any of claims 1 to 5 in which the sheet of thermally-conductive material is a co-laminated sheet comprising aluminium foil and a second materia Use of a thermally-conductive material in an aerosol-generating article according to claim 6 in which the sheet of thermally-conductive material is formed by co-lamination of aluminium foil with paper, or formed by co-lamination of aluminium foil with reconstituted tobacco. Use of a thermally-conductive material in an aerosol-generating article according to any preceding claim in which the aerosol-generating article is for use with an aerosol-generating device comprising an insertable heating element for insertion into a distal end of the heated aerosol-generating article. Use of a thermally-conductive material in an aerosol-generating article according to any of claims 1 to 7 in which the aerosol-generating article is for use with an aerosol-generating device comprising a heating element that surrounds the aerosol-generating article. Use of a thermally-conductive material in an aerosol-generating article according to any preceding claim in which the aerosol-forming substrate comprises homogenised tobacco material comprising between 1% and 5% non-tobacco fibres on a dry weight basis. Use of a thermally-conductive material in an aerosol-generating article according to any preceding claim in which the aerosol-forming substrate comprises homogenised tobacco material having an aerosol former content of between 5% and 30% on a dry weight basis, for example in which the aerosol former is glycerine. Use of a thermally-conductive material in an aerosol-generating article according to any preceding claim in which the aerosol-generating article comprises the aerosol-forming substrate, a hollow cellulose acetate tube, a spacer element, and a mouthpiece filter, arranged sequentially and in co-axial alignment.
