  • the length of the cooling segment 12 is 20 mm
  • the length of the center hole segment 13 is 8 mm
  • the length of the filter segment 14 is 7 mm
  • the length of these individual segments may be changed appropriately depending on manufacturing feasibility, required quality, and so forth. Further, even an article in which only a filter segment is disposed on the downstream side of a cooling segment without using a center hole segment can also act as a heat-not-burn smoking article.
  • a heat-not-burn smoking system includes the heat-not-burn smoking article according to the present invention and a heating device for heating the tobacco-containing segment. Since the heat-not-burn smoking system includes the heat-not-burn smoking article according to the present invention, it is possible to suppress staining on a wrapper and uniformly deliver a volatile component throughout inhalation.
  • the heat-not-burn smoking system according to the present invention is not particularly limited provided that the heat-not-bum smoking article according to the present invention and the heating device are included and may have other configurations.

  • the heating temperature means the temperature of the heater in the heating device.
  • a polymer layer containing a volatile component is provided on the inner surface of a wrapper of the tobacco-containing segment. Since the polymer layer is located near the heater of the heating device during heating, the volatile component contained in the polymer layer is released gradually but in a sufficient amount over a long period of time.
  • solution A A solution (hereinafter, referred to as solution A) was prepared by dissolving 21 g of menthol in 9 g of ethanol.
  • PVA Tg: 58°C, average degree of polymerization: 500, degree of saponification: 85 to 89 mol%) of 45 g was dispersed through mixing in 116 g of water heated to 80°C. Into the resulting mixture, solution A was added while stirring thoroughly with a stirrer to prepare a dispersion.
  • the dispersion was applied to either surface (shred side) of a paper (trade name: 50NFB from Nippon Paper Papylia Co., Ltd., basis weight: 50 g/m 2 ) and dried at 60°C to 90°C to yield a wrapper in which a 20 to 30 ⁇ m-thick polymer layer is formed on the paper. Through the SEM observation of its cross-section, the polymer layer was confirmed to have a porous structure.
  • a paper trade name: 50NFB from Nippon Paper Papylia Co., Ltd., basis weight: 50 g/m 2
  • a commercial heat-not-burn smoking article (trade name: glo regular from British American Tobacco plc) was prepared.
  • the heat-not-burn smoking article does not contain a volatile flavor component, and its portion corresponding to a tobacco-containing segment contains tobacco and glycerol as an aerosol former.
  • a wrapper of the portion corresponding to a tobacco-containing segment is solely made of paper.
  • a heat-not-burn smoking article for evaluation was obtained by removing the wrapper of the portion corresponding to a tobacco-containing segment of the heat-not-burn smoking article and by wrapping the prepared wrapper therearound.
  • a heating device (trade name: glo from British American Tobacco plc) designed for the commercial heat-not-burn smoking article, the portion corresponding to a tobacco-containing segment of the heat-not-burn smoking article for evaluation was heated at 220°C.
  • Smoking was performed in accordance with the Canadian intense smoking regimen. Components in an inhaled aerosol were trapped and subjected to shaking extraction with isopropanol (IPA), and the obtained sample was analyzed by GC. Specifically, smoking was performed as 4 puffs in total by inhaling 55 mL per puff (30 second interval for each puff, i.e. 2 seconds for inhaling and 28 seconds for waiting) in accordance with the CIR (Canadian intense regimen).
  • IPA isopropanol
  • Fig. 6 shows the menthol delivery efficiency, which represents a ratio of the amount of menthol in an inhaled aerosol per puff to the amount of menthol contained in each heat-not-burn smoking article. Moreover, Table 1 shows the total amount of menthol in inhaled aerosols during 4 puffs and the menthol delivery efficiency for 4 puffs in total.
  • the heat-not-burn smoking articles for evaluation was put inside an airtight container and stored in an environment of a temperature of 22°C and a relative humidity of 60% for 4 weeks. Subsequently, the number of stains formed on the wrapper surfaces was visually observed for the heat-not-burn smoking article taken from the container.
  • stains were measured by classifying into those satisfying 0.9 mm ⁇ L ⁇ 2.7 mm (small stain) and those satisfying 2.7 mm ⁇ L (large stain) where L is the maximum size of stains.
  • the evaluation results are shown in Table 2.
  • a unit of stains is each stain that can be approximated by an ellipse (including a circle) regardless of its isolation from other stains.
  • the extent of staining is presented by the number of stained articles and the occurrence (%) of each level with a large or small stain or without stain for 200 heat-not-burn smoking articles.
  • a commercial heat-not-burn smoking article (trade name: glo menthol from British American Tobacco plc) was prepared.
  • a portion corresponding to a tobacco-containing segment of the heat-not-burn smoking article contains menthol as a volatile flavor component and glycerol as an aerosol former.
  • a wrapper of the portion corresponding to a tobacco-containing segment is solely made of paper. It is noted that the amount of menthol contained in this heat-not-burn smoking article is larger than the amount of menthol contained in the heat-not-burn smoking article for evaluation prepared in Example 1.
  • Example 1 The evaluation was performed in the same manner as Example 1 except for using the prepared heat-not-burn smoking article. The results are shown in Fig. 6 and Tables 1 and 2.
  • Table 1 Total amount of menthol [mg/Cig] Menthol delivery efficiency (%) Ex. 1 5.0 51 Comp. Ex. 1 9.4 34
  • Table 2 Small stain (number of articles) Large stain (number of articles) Small stain (%) Large stain (%) No stain (%) Ex. 1 0 0 0 0 100 Comp. Ex. 1 140 60 70 30 0
  • Example 1 the menthol delivery efficiency from the first to the fourth puff was almost uniform in Example 1, in which a wrapper is provided with a polymer layer containing menthol. This is presumably because menthol was gradually released from the polymer layer. Meanwhile, the menthol delivery efficiency linearly decreased from the first to the fourth puff in Comparative Example 1, in which a tobacco filler contains menthol and a wrapper is not provided with a polymer layer containing menthol. This is presumably because much of menthol contained in the tobacco filler was vaporized in the former half of inhalation.
  • Example 1 the menthol delivery efficiency for 4 puffs in total was higher in Example 1 than in Comparative Example 1. This is presumably because menthol is contained within the polymer layer of the wrapper and the polymer layer of the wrapper is located near a heater of the heating device during heating in Example 1. Since the initial amounts of menthol contained in the respective heat-not-burn smoking articles are different, Example 1 and Comparative Example 1 were compared on the basis of the menthol delivery efficiency in Fig. 6 and Table 1.
  • Example 2 As shown in Table 2, no stain was observed on wrapper surfaces in Example 1 whereas stains were observed in Comparative Example 1. This is presumably because bleeding of an aerosol former, a tobacco component, and/or a volatile flavor component contained in a tobacco filler was successfully suppressed in Example 1 due to the presence of the polymer layer.
