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; a first heat-conducting element circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate; a second heat-conducting element around at least a portion of the first heat-conducting element, wherein at least part of the second heat-conducting element is radially separated from the first heat-conducting element; and one or more first air inlets around a periphery of the aerosol-forming substrate.

Smoking article with dual heat-conducting elements and improved airflow

There is provided a heated aerosol-generating article for use with an aerosol-generating device having a heating element, the heated aerosol-generating article including an aerosol-forming substrate and a breachable air-flow barrier assembled within a wrapper to form a rod having a mouth end and a distal end upstream from the mouth end, in which the breachable air-flow barrier is positioned to substantially prevent air being drawn through the aerosol-forming substrate when a user draws on the mouth end of the rod, and in which the aerosol-forming substrate comprises a gathered sheet of aerosol-forming material.

Heated aerosol generating article with air-flow barrier

A heated aerosol-generating article for use with an aerosol-generating device is provided, in the form of a rod having a mouth end and a distal end upstream from the mouth end. An aerosol-forming substrate is located upstream of the mouth end within the rod and the distal end of the heated aerosol-generating article is spanned by a non-flammable thermally-conductive material to reduce the propensity for ignition of the article.

Heated aerosol generating article with thermal spreading endpiece

A rod and a method of forming a rod are provided. The rod includes a gathered sheet of material circumscribed by a wrapper, in which the sheet of material is a co-laminated sheet comprising a layer of an aerosol-forming material and a layer of a thermally-conductive material and in which the wrapper is a metal foil. The method includes providing a continuous co-laminated sheet including an aerosol-forming material and a thermally-conductive material; gathering the co-laminated sheet transversely relative to its longitudinal axis; circumscribing the gathered co-laminated sheet with a metal foil wrapper to form a continuous rod; and severing the continuous rod into a plurality of discrete rods.

Thermal laminate rods for use in aerosol-generating articles

An electrically operated aerosol-generating system is provided, including an aerosol-generating device including an electrically powered heating element; and a heated aerosol-generating article including an aerosol-forming substrate radially encircled by a sheet of thermally-conductive material, which is a thermally conducting flame barrier configured to spread heat and to mitigate against a risk of igniting the substrate by application of a flame to the article, and a plurality of elements, assembled together with the substrate within a wrapper to form a rod having a mouth end and a distal end upstream from the mouth end, the substrate being disposed at the distal end of the rod, the elements including a spacer element disposed within the rod downstream of the substrate and a mouthpiece element extending upstream from the mouth end of the rod, the device being configured to receive the article and the heating element is configured to heat the substrate of the article.

Electrically operated aerosol generating system with thermal spreading wrap

A heated aerosol-generating article for use with an aerosol-generating device is provided, including a plurality of components including an aerosol-forming substrate assembled within a wrapper to form a rod having a mouth end and a distal end upstream from the mouth end, the heated aerosol-generating article defining a first air-flow path in which air drawn into the aerosol-generating article through the mouth end passes through the aerosol-forming substrate, and a second air-flow path in which air drawn into the aerosol-generating article through the mouth end does not pass through the aerosol-forming substrate, the resistance to draw (RTD) of the second air-flow path being lower than the RTD of the first air-flow path when the heated aerosol-generating article is not coupled to an aerosol-generating device.

Aerosol-generating article with low resistance air flow path

A heated aerosol-generating article for use with an aerosol-generating device is provided, the heated aerosol-generating article including a plurality of components including an aerosol-forming substrate assembled within a wrapper to form a rod having a mouth end and a distal end upstream from the mouth end, in which a rigid hollow tube having an external diameter of between 5 mm and 15 mm and a length of between 5 mm and 15 mm is disposed upstream from the aerosol-forming substrate within the wrapper, the rigid hollow tube being substantially non-flammable and in which a pierceable film spans one end of the rigid hollow tube.

Aerosol-generating article with rigid hollow tip

A smoking article is provided, including a combustible heat source having a front portion and a rear portion; an aerosol-forming substrate downstream of the rear portion of the combustible heat source; and a wrapper circumscribing the front portion and the rear portion of the combustible heat source. The wrapper is in contact with the rear portion of the combustible heat source. All or part of the front portion of the combustible heat source is of reduced diameter compared to the rear portion of the combustible heat source so that the wrapper is radially spaced from all or part of the front portion of the combustible heat source by an air gap of at least about 0.5 mm.

Smoking article comprising an insulated combustible heat source

A smoking article is provided, including a combustible heat source having opposed front and rear end faces; an aerosol-forming substrate having opposed front and rear end faces, wherein the front end face of the aerosol-forming substrate is downstream of the rear end face of the combustible heat source; and a non-combustible holder configured to hold the combustible heat source. The holder includes a barrier between the rear end face of the combustible heat source and the front end face of the aerosol-forming substrate, and a plurality of first retention fingers connected to the barrier. The first retention fingers extend from the barrier along the exterior of the combustible heat source.
