Definitions

  • the present invention relates to a flavor inhalation article.
  • heated flavor inhalers that provide users with tobacco flavor by heating the tobacco filler without burning it have been used instead of combustion-type flavor inhalers for cigarettes and the like.
  • the heated flavor inhaler contains a tobacco filler together with an aerosol source.
  • the tobacco filler is heated by the heated flavor inhaler, the moisture and aerosol source in the tobacco filler vaporize, and the tobacco flavor components migrate from the tobacco filler into the gas, generating an aerosol (i.e., tobacco vapor).
  • a typical example of a heated flavor inhaler is an electrically heated flavor inhaler that includes a flavor inhalation article that includes a tobacco filler and a wrapper wrapped around the tobacco filler, and a heating device for electrically heating the flavor inhalation article (see Patent Document 1).
  • the present invention aims to provide a technology that can suppress the increase over time in the diameter of a tip plug placed at the tip of a flavor inhalation article.
  • a tip plug is located at one end of the flavor inhalation article and includes a first filter medium, a first aerosol source supported by the first filter medium, and a first wrapper wrapped around the first filter medium; a filter plug located at the other end of the flavor inhalation article and including a second filter medium; a flavor generating section located between the tip plug and the filter plug and including a flavor source; a second wrapper around the tip plug and the flavor generating section and connecting them;
  • a flavor inhalation article is provided in which the tip portion of the wrapper complex including the first wrapper and the second wrapper, which is located at the most distal end of the one end side of the flavor inhalation article, has a basis weight of 80 g/m2 or more , or the contact angle of the surface in contact with the first filter material is 60° or more.

  • [1] Flavor Inhalation Article In the latter half of the inhalation period, the amount of aerosol (smoke) of the heated flavor inhaler decreases with an increase in the number of inhalations, and the user feels a decrease in the inhalation response. For this reason, the inventors arranged a tip plug on the tip side (i.e., the side opposite to the mouthpiece) of the flavor inhalation article, and made the filter material of the tip plug carry an additional aerosol source. At this time, the inventors encountered a new problem that the diameter of the tip plug increases during storage. The increase in the diameter of the tip plug may lead to the rupture of the tip plug or may cause a problem in the manufacturability when connecting the tip plug to other components of the flavor inhalation article. Therefore, the present invention aims to provide a technology that can suppress the increase in the diameter of the tip plug over time.
  • a tip plug is located at one end of the flavor inhalation article and includes a first filter medium, a first aerosol source supported by the first filter medium, and a first wrapper wrapped around the first filter medium; a filter plug located at the other end of the flavor inhalation article and including a second filter medium; a flavor generating section located between the tip plug and the filter plug and including a flavor source; a second wrapper around the tip plug and the flavor generating section and connecting them;

These five components are connected by a tipping wrapper 270. That is, in the first embodiment, the tipping wrapper 270 connects the tip plug 210 and the flavor generating section 220, and further connects the filter plug 250 to the flavor generating section 220. In Fig. 1, the hollow tube section 230 and the hollow filter section 240 can each be omitted.
  • the tip plug wrap 212 around which the first filter material 211 is wrapped around the tip plug 210 corresponds to the "first wrapper”
  • the tipping wrapper 270 corresponds to the "second wrapper.” Therefore, the tip plug wrap 212 and the tipping wrapper 270 form a "wrapper complex.”
  • the tobacco stick 200 is characterized in that "the tip portion (hereinafter simply referred to as the "tip portion") located at the most distal end of one end of the tobacco stick 200 in the wrapper composite body has a basis weight of 80 g/m 2 or more, or the contact angle of the surface in contact with the first filter medium 211 (i.e., the inner surface of the tip plug wrap 212) is 60° or more.

  • the tip plug is connected to other components of the flavor inhalation article to manufacture the flavor inhalation article, but after manufacture of the tip plug, it is not connected to the other components immediately, but is stored for a while or transported to another factory. Therefore, if the increase in diameter of the tip plug 210 over time is suppressed, the tip plug can be prevented from bursting. Furthermore, if the increase in diameter of the tip plug 210 over time is suppressed, manufacturing suitability problems that arise when connecting the tip plug to other components of the flavor inhalation article due to differences in diameter between the tip plug and the other components can be solved.
