  • the reconstituted tobacco strands can be longitudinal strips.
  • the reconstituted tobacco material can be, for example, band cast reconstituted tobacco material or paper reconstituted tobacco material.

  • the core may have a density of between 0.1 g/cm3 an d 0.9 g/cm3.
  • An advantage of twisting strips of reconstituted tobacco material into a rope like structure is that the strips become interlocked, making them less easily displaced. This is particularly beneficial when the consumable is used with a non-combustible aerosol provision device 200 comprising a pin or blade-like heater that extends into the area 201 for receiving the consumable too.
  • a pin or blade-like heater is configured to penetrate the consumable too along its axis to heat the aerosol generating material 105. It has been found that consumables comprising strands of reconstituted tobacco material that are not formed into a twisted rope like structure tend to be displaced by such heaters, leaving debris with the area 201 for receiving the consumable. During longer term use of the device, this debris can accumulate to the detriment of heater efficiency and hygiene.

  • Such example consumables too are configured for use with a device 200 comprising an aerosol generator 202 configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable too, as explained further below.
  • the susceptor 107 of each strand 102 is heated by the varying magnetic field to heat the aerosol generating material 105 and form an aerosol for inhalation by the user.
  • the susceptor 107 of each strand 102 comprises a twisted rope-like structure.
  • the susceptors 207 may take any form suitable for their integration into the strands 102. Therefore, the susceptors 207 are preferably formed of a resiliently flexible material that allows them to follow the helical path of the strands 102 in which they are embedded. In the illustrated example, each susceptor 107 is embedded substantially centrally within a strand 102.
  • Such example consumables too maybe formed by extruding a strand 102 of aerosol generating material 105 around a continuous length of susceptor 107. Each strand 102 is then cut to length and twisted about at least one other such strand 102 to form the rope-like structure of the core 101, as will be explained further below.

  • the consumable too is provided with a smooth, generally cylindrical appearance.
  • the outer wrapper 108 forms an outer surface of the consumable too. Therefore, wrapping the core 101 in an outer wrapper 108 prevents the user from having to handle the core 101 directly. This maybe beneficial to stop the user getting any of the aerosol generating material 105 on them where they touch the consumable too.
  • a further advantage of the outer wrapper 108 is that air flow channels 109 are formed between the outer wrapper 108 and the core 101.
  • the air flow channels 109 follow the helical groove formed between strands 102 of the rope-like structure.
  • the air flow channels 209 form a helical air flow pathway that extends from a distal end too” of the consumable to a mouth end too’.
  • the length of the helical air flow pathway formed by the air flow channels 209 is greater than if the air flow pathway were straight. That is to say, the length of the helical air flow pathway is greater than a straight air flow pathway that extends over the same axial length of the consumable too.
  • the residence time of air drawn through the consumable too is greater than if the air flow pathway were straight. This allows more of the constituent parts of the aerosol formed during use to be entrained into the air drawn along the air flow pathway.
  • Another effect of the helical airflow pathway is that the pressure drop across the consumable is greater than if the airflow pathway were straight.
  • the length of the airflow pathway can be affected by the pitch P of the helix formed by each strand 102 of the core 101.
  • the pitch P of the helix formed by each strand 102 of the core is defined as the length of one complete turn of the strand 102, measured parallel to the longitudinal axis X-X of the consumable too.
  • Fig. 1 illustrates the pitch P of a three strand 102 core 101. Increasing the pitch P will reduce theisressuree drop of the consumable too and the residence time of air drawn through the consumable. In one example, the pitch P is between 0.2 and 1.5 times the diameter D of the helix formed by each strand 102.
  • the outer wrapper 108 may extend along the entire length of the core 101 or may extend only partially along the length of the core 101, as illustrated in Fig. 5. In the example of Fig. 5, the outer wrapper extends 108 from the mouth end too’ of the consumable too over a portion of the length of the core 101.
  • the mouth end 101’ of the consumable too is herein defined as the part of the consumable too placed between the lips of a user to allow the user to draw on the consumable too. Therefore, the user’s lips do not come into contact with the aerosol generating material 105 during use.
  • the device 200 may be provided with a mouthpiece (not shown) which moveably encloses the area 201 for receiving the consumable too.

  • the user may then draw on the consumable too or, alternatively, on a mouthpiece (not shown) of the device 200 to inhale the aerosol.
  • the consumable too and device 200 are configured so that mouth end too’ of the consumable too protrudes from the area 201 for receiving the consumable too when fully inserted into the device 200. Therefore, the consumable too is available for placing between the lips of the user while the user holds the device 200.
  • the puff sensor 205 is configured to detect when a user is drawing on the consumable too within the device 200 and to send a signal to the controller 204 to activate the aerosol generator 202. Therefore, aerosol is generated concurrently with the user inhaling on the consumable too.
  • the device 200 maybe provided with a user interface - such as a button (not shown) - that the user may interact with to cause activation of the aerosol generator 202.
  • the area 201 for receiving the consumable too is provided with an inlet (not shown) to allow air into the area 201 for passing through the consumable too when a user inhales on the mouth end too’ of the consumable too. Therefore, a flow of air is directed through the consumable too when a user draws on the consumable too. More particularly, the flow of air is directed along the airflow pathway of the consumable too. The flow of air entrains the aerosol generated by the aerosol generating material 105 of the consumable too when heated by the aerosol generator 202.
  • the aerosol generator 202 comprises any suitable means for heating the aerosol generating material 105 of a consumable received in said area 201 of the device 200.
  • the aerosol generator 202 comprises a magnetic field generator configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable too.
  • the varying magnetic field heats a susceptor 107, 111 that is placed within the area 201 for the receiving the consumable too by magnetic hysteresis.
  • This example may be used, therefore, with a consumable too comprising a material heatable by a varying magnetic field, as described above.
  • the aerosol generator 202 comprises a susceptor in thermal contact with the area 201 for receiving the consumable; and a magnetic field generator for generating a varying magnetic field that penetrates the susceptor.
  • the varying magnetic field heats the susceptor by magnetic hysteresis.
  • the susceptor in turn heats the area 201 for receiving the consumable.
  • the susceptor may be the wall 207 of the area 201 for receiving the consumable too and the consumable too may be configured for direct contact with the wall 207 for efficient heat transfer.
  • the aerosol generator 202 comprises a material heatable by electrical conduction, the material being provided in thermal contact with the area 201 for receiving the consumable too. Therefore, when a consumable too is placed within the device 200 and the aerosol generator 202 is activated, a current is passed through the material to heat area 201 in which the consumable too is received. The heat is transferred to the aerosol generating material 105 of the consumable too, generating an aerosol for inhalation by the user.
  • the material may be the wall 207 of the area 201 for receiving the consumable too and the consumable too maybe configured for direct contact with the wall 207 for efficient heat transfer.
