Definitions

  • the present invention relates to a tobacco composition, a tobacco-containing segment, a non-combustion heating-type flavor inhaler, and a non-combustion heating-type flavor inhalation system.
  • a tobacco-containing segment with a tobacco filler containing leaf tobacco is burned to taste a flavor.
  • a non-combustion heating-type flavor inhaler has been proposed in which a tobacco-containing segment is not burned but heated to taste a flavor.
  • the heating temperature of a non-combustion heating-type flavor inhaler is lower than the combustion temperature of a combustion-type flavor inhaler and is approximately 400°C or less, for example.
  • an aerosol generator such as glycerin, is added to a tobacco filler in the non-combustion heating-type flavor inhaler to increase the amount of smoke.
  • An aerosol generator is vaporized by heating and generates an aerosol. A user is supplied with the aerosol together with a tobacco component and can taste sufficient flavor.
  • a tobacco filler filled with a tobacco sheet instead of leaf tobacco is typically used as a tobacco filler so that the tobacco filler can contain a sufficient amount of aerosol generator (for example, Patent Literature 1).
  • the tobacco sheet is manufactured by forming a composition containing tobacco into a sheet shape and contains fiber, such as pulp, as a filler for the forming. Because the fiber can absorb an aerosol generator, the tobacco sheet can hold a larger amount of aerosol generator than leaf tobacco.
  • Patent Literature 2 to Patent Literature 6 disclose a tobacco composition containing leaf tobacco and a tobacco sheet, mainly for use in a combustion-type flavor inhaler.
  • a tobacco filler in a tobacco-containing segment of a non-combustion heating-type flavor inhaler is typically composed only of a tobacco sheet containing both a tobacco component and an aerosol generator.
  • the amount of heat should be controlled to reach a temperature into which the saturated vapor pressure of a flavor component is considered.
  • the amount of heat should be controlled to reach an evaporation temperature into which the specific heat (heat capacity) of an aerosol generator is considered. It is thought that the amount of heat and temperature required for the phenomena of developing a tobacco flavor and generating an aerosol are different. Thus, for a material containing both a tobacco component and an aerosol generator, it is difficult to improve both phenomena at the same time.
  • the present invention includes the following aspects.
  • a tobacco-containing segment according to an embodiment of the present invention includes a tubular wrapper and a tobacco filler, wherein the tobacco filler contains a tobacco composition according to an embodiment of the present invention filled in the wrapper.

  • the tobacco composition according to the present embodiment may be composed of the first material and the second material.
  • the present inventors have found that the use of a blend of two materials specific to the phenomena of developing a tobacco flavor and generating an aerosol allows each material to use only the required amount of heat for heating and can cause both phenomena at the same time.
  • the first material containing the tobacco component and having an aerosol generator content of less than 25% by mass is a material specific to developing a tobacco flavor and, due to its low specific heat (heat capacity), can easily reach the evaporation temperature of a flavor component by heating.

  • the mass ratio of the second material is 15% by mass or more, a sufficient amount of aerosol can be generated.
  • the tobacco composition according to the present embodiment is particularly useful as a tobacco composition for a non-combustion heating-type flavor inhaler.
  • the tobacco composition according to the present embodiment preferably has an aerosol generator content in the range of 10% to 40% by mass.

  • the CBT content of the first material is measured by the following method.
  • the first material may contain an aerosol generator and has an aerosol generator content of less than 25% by mass. When the content is less than 25% by mass, the vaporization of a flavor component is not prevented, and a tobacco flavor is developed.
