The present disclosure provides aerosol generating substrates and aerosol source members comprising aerosol generating substrates, as well as methods of manufacturing thereof. In an example implementation, an aerosol generating substrate may comprise a fibrous filler material, an aerosol forming material, and a plurality of heat conducting constituents, wherein the substrate is formed as a sheet, and wherein the heat conducting constituents are part of the sheet. The heat conducting constituents may be incorporated within the sheet, or may be formed on a surface of the sheet. In another example implementation, an aerosol source member may comprise a substrate portion formed of a collection of intermingled pieces cut from an aerosol substrate sheet. In addition, or alternatively, a substrate portion may be formed of a series of overlapping layers of an aerosol substrate sheet.

Heat conducting substrate for electrically heated aerosol delivery device

The present disclosure provides a control body, an aerosol delivery device, and a method of operating an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control body having a housing, an electrical energy source located within the housing, a heating member operatively connected to the electrical energy source, an aerosol source member that includes an inhalable substance medium, and an indexing mechanism coupled to the heating member. The indexing mechanism is configured to move the heating member relative to the aerosol source member so as to sequentially heat one of two or more segments of the aerosol source member.

Smoking articles are disclosed herein. The present disclosure is directed to a smoking article that comprises a heat source configured to generate heat upon ignition thereof, a substrate material having opposed first and second ends, the heat source being disposed proximate the first end of the substrate material and the substrate material having an aerosol precursor composition associated therewith, a mouthpiece, the mouthpiece being disposed proximate the second end of the substrate material, and a heat transfer component. In one implementation, the heat transfer component comprises a hollow structure and opposing first and second flanges located on respective ends thereof, wherein the hollow structure extends through the heat source such that the heat source is located between the first and second opposing flanges. In another implementation, the heat transfer component is located within the heat source, penetrates at least a portion of the substrate material, and includes a cap located between the heat source and the substrate material.

The present disclosure is directed to a smoking article that comprises a holder that includes a receiving end and a mouth end, a removable cartridge configured to be received at the receiving end of the holder, the removable cartridge comprising a heat source configured to generate heat upon ignition thereof, and a substrate portion having opposed first and second ends, the heat source being disposed proximate the first end of the substrate portion, and the substrate portion including a substrate material having an aerosol precursor composition associated therewith, and an ejection mechanism configured to move the cartridge relative to the holder between a received position and an ejected position. In one implementation, the ejection mechanism comprises a pusher pin, a guide ring, a carrier sleeve, and a spring, wherein the cartridge is configured to be received into the carrier sleeve, and wherein the pusher pin is configured to move relative to the guide ring so as to actuate the carrier sleeve alternately between the received position and the ejected position.

The present invention provides a conductive substrate useful for Joule heating, such as in an electronic smoking article. Particularly, the invention provides a resistive heating element formed of a conductive substrate. The conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. It has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.

A cigarette includes lighting and mouth ends. It may include a smokable segment disposed at the lighting end. It also includes a mouth-end segment; an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment adjacent the smokable segment, including a heat source configured to be activated by combustion of a smokable material and an insulation layer of a non-glass material that is woven, knit, or both, and (ii) an aerosol-generating segment with aerosol-forming material disposed between, but physically separate from, each of the heat generation segment and the mouth end; a piece of outer wrapping material that provides an overwrap around at least a portion of the aerosol-generating segment, the heat-generation segment, and at least a portion of the smokable segment; those segments being connected together by the overwrap to provide a cigarette rod; that is connected to the cigarette rod using tipping material.

A filter element incorporating an adsorbent material is provided. The filter element may comprise a first section of filter material and a second section of filter material spaced apart to form a compartment therebetween. The compartment may be filled with one or more adsorbents or the compartment may be divided into two regions, wherein one compartment region is filled with an adsorbent and the other compartment region is either filled with an ion-exchange resin or remains empty. The section of filter material adjacent to the tobacco rod may include one or more channels therethrough for passaging smoke directly from the tobacco rod into the adsorbent-filled compartment. The mouth end section of filter material may contain a breakable capsule, wherein the breakable capsule is filled with a flavoring agent capable of altering the taste characteristics of mainstream smoke.
