  • Induction heating is a process in which an electrically-conductive object is heated by penetrating the object with a varying magnetic field.
  • An induction heater may comprise an electromagnet and a device for passing a varying electrical current, such as an alternating current, through the electromagnet.
  • a varying electrical current such as an alternating current
  • the electromagnet and the object to be heated are suitably relatively positioned so that the resultant varying magnetic field produced by the electromagnet penetrates the object, one or more eddy currents are generated inside the object.
  • the object has a resistance to the flow of electrical currents. Therefore, when such eddy currents are generated in the object, their flow against the electrical resistance of the object causes the object to be heated. This process is called Joule, ohmic, or resistive heating.
  • An object that is capable of being inductively heated is known as a susceptor.
  • Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by penetrating the object with a varying magnetic field.
  • a magnetic material can be considered to comprise many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such material, the magnetic dipoles align with the magnetic field. Therefore, when a varying magnetic field, such as an alternating magnetic field, for example as produced by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the varying applied magnetic field. Such magnetic dipole reorientation causes heat to be generated in the magnetic material.

  • the article 1 comprises a sheet 10 comprising reconstituted smokable material, and heating material 20 that is heatable by penetration with a varying magnetic field to heat the smokable material. Examples of such heating material are described below.
  • the article 1 is for use with apparatus for heating the smokable material to volatilize at least one component of the smokable material without burning the smokable material.
  • Such an apparatus may comprise a magnetic field generator for generating a varying magnetic field to be used in heating the heating material.
  • An example such apparatus 100 is shown in FIG. 9 and described below.
  • the sheet 10 is planar, or substantially planar.
  • the sheet 10 is bendable or rollable so as to from a rolled sheet.
  • rolled sheet it is meant that the sheet 10 is curved, such as without folding, so that the sheet 10 has an elongate spiral or tubular shape. Such a rolled sheet may be less prone to damage, more convenient to store and handle, and better suited for use with the apparatus than the planar sheet.
  • the heating material 20 is in contact with the sheet 10 . More specifically, in this embodiment, the heating material 20 is on a surface of the sheet 10 . Still more specifically, in this embodiment, all or substantially all of a surface of the sheet 10 is covered by a layer that comprises the heating material 20 .
  • the layer may be a foil layer.
  • the surface of the sheet 100 may be only partially covered by the heating material 20 .
  • the heating material 20 may be on both opposite surfaces of the sheet 10 . For example, in some embodiments, all, substantially all, a majority, or only a portion of each of two opposite surfaces of the sheet 10 may be covered by heating material 20 .
  • FIG. 2 there is shown a schematic perspective view of an example of another article according to an embodiment.
  • the article 2 of FIG. 2 is identical to the article 1 described above with reference to FIG. 1 , other than the manner in which heating material is provided in the article 2 .
  • Any of the herein-described possible variations to the article 1 of FIG. 1 may be made to the article 2 of FIG. 2 to form separate respective embodiments.
  • the heating material 20 again is on a surface of the sheet 10 comprising reconstituted smokable material.
  • the article 2 comprises a plurality of discrete bodies 22 a, 22 b, 22 c, 22 d on a surface of the sheet 10 , and each of the discrete bodies 22 a, 22 b, 22 c, 22 d comprises the heating material 20 .
  • each of the discrete bodies 22 a, 22 b, 22 c, 22 d comprises a strip or track 22 a, 22 b, 22 c, 22 d on a surface of the surface of the sheet 10 .

Regions of the smokable material adjacent the wider or thicker tracks may then be heated to a lesser degree by the application of a given varying magnetic field than regions of the smokable material adjacent the narrower tracks.
  • the width and/or thickness of one or more of the strips 22 a, 22 b, 22 c, 22 d may vary along the path the strip follows. Therefore, in some embodiments, one or more portions of the heating material 20 is/are able to heat first region(s) of the smokable material relatively quickly to initialize volatilization of at least one component of the smokable material and formation of vapor in the first region(s) of the smokable material, and one or more portions of the heating material 20 is/are able to heat second region(s) of the smokable material relatively slowly to initialize volatilization of at least one component of the smokable material and formation of vapor in the second region(s) of the smokable material.
  • vapor is able to be formed relatively rapidly for inhalation by a user, and vapor can continue to be formed thereafter for subsequent inhalation by the user even after the first region(s) of the smokable material may have ceased generating vapor.
  • a given region of the smokable material may cease generating the vapor when the region becomes exhausted of volatilizable components of the smokable material.
  • the heating material 20 may have a skin depth, which is an exterior zone within which most of an induced electrical current and/or induced reorientation of magnetic dipoles occurs.
  • a skin depth is an exterior zone within which most of an induced electrical current and/or induced reorientation of magnetic dipoles occurs.
  • the strip or strips 22 a, 22 b, 22 c, 22 d is/are in the form ink comprising the heating material 20 .
  • the ink may be printed on the sheet 10 , for example using gravure printing. Ink may have a small thickness. Therefore, induced electrical current and/or induced reorientation of magnetic dipoles in the ink when subjected to a varying magnetic field may penetrate most or all of the ink, rather than be confined to just a “skin” thereof as can be the case when a component comprising heating material has too great a thickness. Thus, a more efficient use of material is achieved and, in turn, costs are reduced.
