Definitions

  • the present invention relates to a tobacco sheet for a non-combustion heating flavor inhaler, a non-combustion heating flavor inhaler, and a non-combustion heating flavor inhalation system.
  • a combustion-type flavor inhaler obtains flavor by burning a tobacco filling containing leaf tobacco.
  • a non-combustion heating type flavor inhaler has been proposed that obtains flavor by heating a flavor source such as a tobacco sheet instead of burning it.
  • the heating temperature of the non-combustion-heating flavor inhaler is lower than the combustion temperature of the combustion-type flavor inhaler, for example, about 400° C. or less.
  • an aerosol generating agent can be added to the flavor source in the non-combustion heating type flavor inhaler from the viewpoint of increasing the amount of smoke.
  • the aerosol-generating agent is vaporized by heating to generate an aerosol. Since the aerosol is supplied to the user together with flavor components such as tobacco components, the user can obtain sufficient flavor.
  • a non-combustion heating flavor inhaler can comprise, for example, a tobacco-containing segment filled with tobacco sheets or the like, a cooling segment, and a filter segment.
  • the axial length of the tobacco-containing segment of the non-combustion-heating flavor inhaler is generally shorter than the axial length of the tobacco-containing segment of the normal combustion-type flavor inhaler in relation to the heating heater. Therefore, in the non-combustion heating type flavor inhaler, a large amount of tobacco sheets or the like is filled in the short tobacco-containing segments in order to ensure the amount of aerosol generated during heating.
  • non-combustion heating type flavor inhalers usually use tobacco sheets with low swelling, that is, high density tobacco sheets.
  • the swelling property is a value indicating the volume of a tobacco sheet having a predetermined mass when notches are compressed under a constant pressure for a certain period of time.
  • Patent Literatures 1 and 2 disclose tobacco sheets for use in non-combustion heating flavor inhalers.
  • the present inventors believe that if a tobacco sheet with low swelling (high density) is used, the total heat capacity of the tobacco-containing segment increases.

In order to solve this problem, it is conceivable to reduce the total heat capacity of the tobacco-containing segment.
  • the present inventors (1) reduce the specific heat of the tobacco raw material contained in the tobacco sheet, and (2) use a highly bulky (low-density) tobacco sheet. I considered using it. However, as for (1), it is difficult to reduce the specific heat of the tobacco raw material itself, so it was considered effective to reduce the total heat capacity of the tobacco-containing segment by (2). Therefore, it is desired to develop a highly bulky (low density) tobacco sheet suitable for non-combustion heating type flavor inhalers.
