The smoking article includes a downstream end portion (i.e., the portion where air enters) and an upstream end portion (i.e., the portion where air exits) opposite thereto. When using the smoking article, the user can bite the downstream end portion of the smoking article. The downstream end portion is also called the proximal end (mouth end, ME), and the upstream end portion is also called the distal end (tobacco end, TE). The term "end portion" can also be described as "terminal end".

[0038] FIG. 1 is a view showing a smoking article according to an embodiment.

[0039] Referring to FIG. 1, a smoking article 100 according to an embodiment may include a medium accommodating portion 110, a humectant accommodating portion 120 located on one side of the medium accommodating portion to generate an aerosol, and a filter portion 130 located on the other side of the medium accommodating portion. The segments of the smoking article 100, i.e., the medium accommodating portion 110, the humectant accommodating portion 120, and the filter portion 130, may or may not be wrapped by a segment wrapper 140 respectively. The segments wrapped by the segment wrapper 140 may be wrapped by a total wrapper 150 to form one smoking article.

[0040] In the present invention, the "medium-receiving portion 110" may be filled with a plurality of tobacco sheets, tobacco shreds, or tobacco granules. The tobacco sheet may be formed by folding a flat sheet coated with a tobacco medium several times. In this case, the tobacco medium may be a liquid type, and may be glycerin, menthol, nicotine, or the like, or a combination thereof, and the flat sheet may be crimping paper, general paper base paper, or the like, but is not limited thereto. The tobacco shreds refer to a solid material based on tobacco raw materials, and the medium-receiving portion may be manufactured by finely cutting general shreds or a slurry plate-like leaf sheet, and may be formed by combining a plurality of tobacco shreds in the same direction or randomly. In addition, the medium-receiving portion may be in a form in which a plurality of tobacco granules are contained in a flat sheet coated with a tobacco medium, and the tobacco medium may be glycerin, menthol, nicotine, or the like, or a combination thereof, and the flat sheet may be crimping paper, general paper base paper, or the like, but is not limited thereto.

[0041] Meanwhile, the medium receiving portion 110 may further contain other additives such as a humectant, a flavoring agent, and / or an organic acid. The humectant may be glycerin, propylene glycol, ethyl alcohol, or the like. The flavoring agent may be, but is not limited to, licorice, sucrose, fructose syrup, isosweetener, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, kellaway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, or coffee.

[0042] In the present invention, the "humectant storage part 120" can contain a humectant. The humectant can include glycerin and propylene glycol, and can further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, oleyl alcohol, and water. Further, the humectant storage part can further contain nicotine. However, the substances contained in the humectant storage part 120 are not limited to these. The humectant can maintain the moisture in the aerosol generated when the smoking article is heated at an appropriate level, soften the tobacco-specific flavor, and enrich the atomization amount.

[0043] In the present invention, the "filter part 130" is composed of at least one or more segments and can include at least one of a tube filter, a cooling structure, and a recess filter. Preferably, it can include a first filter part 132 having a cavity inside and a second filter part 134 filled with a filtering substance inside. The filtering substance can include cellulose-based substances (such as acetate, paper, etc.).

[0044] In the present invention, the "segment wrapper 140" can be any one or more selected from the group consisting of a medium storage part wrapper 142, a humectant storage part wrapper 144, a first filter part wrapper 146, and a second filter part wrapper 148. As the segment wrapper 140, water-resistant paper having water-resistant performance, oil-resistant paper having oil-resistant performance, or water-resistant and oil-resistant paper having water-resistant and oil-resistant performance, or paper coated with a substance having water-resistant and / or oil-resistant performance on the inside can be used. The segment wrapper 140 of the present invention can contain aluminum having waterproof and heat-resistant characteristics. When the segment wrapper is composed of a double-layer paper, the aluminum can be located between the outer wrapper paper and the segment, and when it is composed of a triple-layer paper, it can be located between the outer wrapper paper and the inner wrapper paper. At this time, the outer wrapper paper and the inner wrapper paper can be 100% wood pulp. Considering the induction heating characteristics, the triple-layer paper containing aluminum is preferably applied to the medium storage part wrapper 142.

[0045] In order to perform physical property measurement, aerosol component analysis, sensory evaluation, and medium accommodation part temperature measurement of a smoking article according to an embodiment of the present invention, a medium accommodation part wrapper 142 was manufactured as shown in Table 1 below, and a smoking article including the medium accommodation part wrapper 142 was manufactured as shown in Table 2 below.

[0046] [Table 1]

[0047] The medium accommodation part wrapper 142 of the present invention is composed of triple-ply paper. Among them, the outer wrapping paper 1422 and the inner wrapping paper 1426 have a thickness of 35 μm and a basis weight of 16 gsm, and the middle wrapping paper 1424 has a basis weight of 54.2 gsm and contains 20 μm of aluminum (Figure 2).

[0048] For comparison, double-ply paper was manufactured as a control group and used as the medium accommodation part wrapper. The double-ply paper is composed of double wrapping paper. Among them, the outer wrapping paper has a thickness of 44 μm and a basis weight of 35 gsm, and the middle wrapping paper has a basis weight of 18 gsm and contains 6.3 μm of aluminum.

[0049] [Table 2]

[0050] [Experimental Example 1. Physical Property Measurement] First, the physical property measurement results of the medium accommodation part 110 wrapped with the medium accommodation part wrapper 142 composed of triple-ply paper containing 20 μm thick aluminum are shown in Table 3, and the physical property measurement results of the smoking article including the medium accommodation part 110 are shown in Table 4.

[0051] [Table 3] [Table 4]

[0052] As a result of physical measurements, the physical levels such as weight, circumference, and suction resistance of the control group and the experimental group were similar.

[0053] [Experimental Example 2. Aerosol Component Analysis] The results of analyzing the components of the aerosol under 9 puff and pack harmonization conditions using the HC (Health Canada) method, which is an internationally recognized analysis method for general tobacco, are shown in Table 5 below.

[0054]

Table 5

[0055] As a result, it was confirmed that the aerosol of the experimental group contained a much larger amount of total particulate matter (TPM), tar (total aerosol residue, TAR), nicotine, propylene glycol, glycerin, water, and menthol compared to the control group. In particular, glycerin showed a 43% and menthol showed a 33% increase in the transfer amount. This suggests that the smoking article of the present invention has a richer atomization amount and is excellent in taste and aroma.

[0056] In addition, in order to examine the transfer amount at the initial suction, the results of analyzing the components of the aerosol under 3 puff and pack harmonization conditions using the above-mentioned HC (Health Canada) method are shown in Table 6 below.

[0057]

Table 6

[0058] Even at the initial suction, the transfer amounts of total particulate matter (TPM), tar (TAR), glycerin (Gly), water, and menthol were all shown to be high. In particular, glycerin had a 29.5% and menthol had a 15.8% increase in the transfer amount.

[0059] [Experimental Example 3. Sensory Evaluation] The heat sensation, initial atomization amount, total atomization amount, menthol intensity, irritation, menthol persistence, and overall tobacco flavor felt from the smoking article were evaluated. The sensory evaluation was measured by a 7-point scoring method after sucking about 10 to 14 puffs for experts with experience in sensory evaluation in the field of smoking articles, and the results are shown in Table 7 below.

[0060]

Table 7

[0061] As a result, the initial atomization amount, total atomization amount, menthol intensity, menthol persistence, and overall tobacco flavor of the smoking article were all improved. In particular, in the case of the initial atomization amount, total atomization amount, menthol intensity, menthol persistence, and overall tobacco flavor, it was confirmed that there was a statistically significant difference between the two groups.

[0062] Figures 3 and 4 are related to the mode in which a smoking article 100 including a medium accommodation part wrapper 142 composed of a triple laminate paper containing aluminum is used.

[0063] Figure 3 is a diagram schematically showing an aerosol generator 200 according to an embodiment.

[0064] Referring to Figure 3, the aerosol generator 200 includes an elongated cavity 210 for accommodating the smoking article 100, a heater 220, and a control unit 230. The control unit 230 can be electrically connected to the heater 220 to control the temperature for heating the smoking article 100. The aerosol generator 200 can further include a battery 240 for supplying power in the process of generating aerosol.

[0065] Figure 4 is a diagram schematically showing an aerosol generation system 10 in a state where a smoking article 100 according to an embodiment and an aerosol generator 200 are combined.

[0066] Referring to FIG. 4, the aerosol generating system 10 can include a smoking article 100 and an aerosol generating device 200. The smoking article 100 can be tightly coupled within the elongated cavity 210 of the aerosol generating device 200. With the smoking article 100 coupled to the aerosol generating device 200, the heater 220 can heat at least all or part of the medium accommodating portion 110 and the humectant accommodating portion 120 of the smoking article 100, preferably heating the downstream of the humectant accommodating portion 120 and the upstream of the medium accommodating portion 110.

[0067] Specifically, for the smoking article, the length of the humectant accommodating portion 120 can be 10 mm, the length of the medium accommodating portion 110 can be 12 mm, the length of the first filter portion 132 can be 12 mm, and the length of the second filter portion 134 can be 14 mm. At this time, the heater 220 can heat 7 mm downstream of the humectant accommodating portion 120 and 7 mm upstream of the medium accommodating portion 110.

[0068] [Experimental Example 4. Measurement of Medium Accommodating Portion Temperature] The temperatures of the heated portion and the unheated portion of the medium accommodating portion 110 of the smoking article according to an embodiment of the present invention were measured. The temperature of the heated portion was the temperature of the medium accommodating portion located 33 mm from the proximal end (mouth end, ME) (FIG. 4 (i)), and the temperature of the unheated portion was the temperature of the medium accommodating portion located 28 mm from the proximal end (FIG. 4 (ii)). The measurement results are shown in Table 8 and FIG. 5.

[0069]

Table 8

[0070] The medium accommodating portion of the present invention not only maintains the temperature of the heated portion at about 200 °C, but also maximizes the heat transfer efficiency to improve the temperature of the unheated portion as a whole, thereby increasing the atomization amount of the smoking article.
