Abstract

An aerosol delivery device and an aerosol source member for use with an aerosol delivery device are provided. In various implementations, the aerosol source member comprises a substrate portion that includes a plurality of spaced susceptor bands. In one implementation, each susceptor band comprises a plurality of susceptor coils that are radially spaced around the longitudinal axis of the substrate portion, wherein each of the susceptor coils defines a longitudinal axis thereof, and wherein the longitudinal axis of each of the plurality of susceptor coils is substantially parallel to the longitudinal axis of the substrate portion. In another implementation, each susceptor band extends through the center of the substrate portion and across a diameter thereof, and wherein each susceptor band comprises a plurality of spaced susceptor particles.

Claims (9)

  1. 1 . An aerosol source member for use with an induction heated aerosol delivery device having a resonant transmitter, said aerosol source member comprising: a substrate portion comprising: a core portion; a surrounding portion disposed around the core portion; and a radial cover layer disposed around the surrounding portion, wherein the core portion includes a plurality of susceptor particles distributed therein having a first distribution density, wherein the surrounding portion includes a plurality of susceptor particles distributed therein having a second distribution density, and wherein the first distribution density is greater than the second distribution density, wherein the plurality of susceptor particles of the core portion are evenly distributed with respect to each other, wherein the plurality of susceptor particles of the surrounding portion are evenly distributed with respect to each other, and wherein the substrate portion comprises three separate radial layers: a first radial layer comprising the core portion, a second radial layer comprising the surrounding portion, and the radial cover layer.
  2. 2 . The aerosol source member of claim 1 , wherein the core portion and the surrounding portion comprise the same substrate material having different susceptor particle distribution densities.
  3. 3 . The aerosol source member of claim 1 , wherein the radial cover layer comprises a foil sublayer and a paper sublayer disposed around the foil sublayer.
  4. 4 . The aerosol source member of claim 1 , wherein at least one susceptor particle of the plurality of susceptor particles has a shape selected from a flake-like shape, a spherical shape, a hexagonal shape, a cubic shape, and an irregular shape.
  5. 5 . The aerosol source member of claim 1 , wherein at least one susceptor particle of the plurality of susceptor particles of the core portion or the surrounding portion comprises a material selected from a cobalt material, an iron material, a nickel material, a zinc material, a manganese material, a stainless steel material, a ceramic material, a silicon carbide material, a carbon material, and combinations thereof.
  6. 6 . The aerosol source member of claim 1 , wherein the substrate portion comprises an extruded tobacco material.

Description

TECHNOLOGICAL FIELD The present disclosure relates to aerosol source members, aerosol delivery devices, and uses thereof for yielding tobacco components or other materials in inhalable form. More particularly, the present disclosure relates to aerosol source members and aerosol delivery devices and systems, such as smoking articles, that utilize electrically-generated heat to heat tobacco or a tobacco derived material, preferably without significant combustion, in order to provide an inhalable substance in the form of an aerosol for human consumption. BACKGROUND Many smoking articles have been proposed through the years as improvements upon, or alternatives to, smoking products based upon combusting tobacco. Exemplary alternatives have included devices wherein a solid or liquid fuel is combusted to transfer heat to tobacco or wherein a chemical reaction is used to provide such heat source. Examples include the smoking articles described in U.S. Pat. No. 9,078,473 to Worm et al., which is incorporated herein by reference in its entirety. The point of the improvements or alternatives to smoking articles typically has been to provide the sensations associated with cigarette, cigar, or pipe smoking, without delivering considerable quantities of incomplete combustion and pyrolysis products. To this end, there have been proposed numerous smoking products, flavor generators, and medicinal inhalers which utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar, or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices and heat generating sources set forth in the background art described in U.S. Pat. No. 7,726,320 to Robinson et al.; and U.S. Pat. App. Pub. Nos. 2013/0255702 to Griffith, Jr. et al.; and 2014/0096781 to Sears et al., which are incorporated herein by reference in their entireties. See also, for example, the various types of smoking articles, aerosol delivery devices and electrically powered heat generating sources referenced by brand name and commercial source in U.S. Pat. App. Pub. No. 2015/0220232 to Bless et al., which is incorporated herein by reference in its entirety. Additional types of smoking articles, aerosol delivery devices and electrically powered heat generating sources referenced by brand name and commercial source are listed in U.S. Pat. App. Pub. No. 2015/0245659 to DePiano et al., which is also incorporated herein by reference in its entirety. Other representative cigarettes or smoking articles that have been described and, in some instances, been made commercially available include those described in U.S. Pat. No. 4,735,217 to Gerth et al.; U.S. Pat. Nos. 4,922,901, 4,947,874, and 4,947,875 to Brooks et al.; U.S. Pat. No. 5,060,671 to Counts et al.; U.S. Pat. No. 5,249,586 to Morgan et al.; U.S. Pat.
