[0038] FIG. 1 is a diagram showing a smoking article according to one embodiment.

[0039] Referring to FIG. 1, a smoking article 100 according to one embodiment may include a medium accommodating section 110, a moisturizing agent accommodating section 120 located on one side of the medium accommodating section to generate an aerosol, and a filter section 130 located on the other side of the medium accommodating section. The segments of the smoking article 100, i.e., the medium accommodating section 110, the moisturizing agent accommodating section 120, and the filter section 130, may or may not be wrapped by a segment wrapper 140, and 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 moisturizer, a flavoring agent, and / or an organic acid. The moisturizer may be glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol, and the flavoring agent may be 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, but is not limited thereto.

[0042] In the present invention, the "humectant-containing section 120" may contain a humectant. The humectant may include glycerin and propylene glycol, and may further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, oleyl alcohol, and water. The humectant-containing section may further include nicotine. However, the substances contained in the humectant-containing section 120 are not limited thereto. The humectant may maintain the moisture in the aerosol generated when the smoking article is heated at an appropriate level, softening the inherent taste of tobacco and enriching the amount of atomization.

[0043] In the present invention, the "filter unit 130" is composed of at least one or more segments and may include at least one of a tube filter, a cooling structure, and a recess filter, and may preferably include a first filter unit 132 having a cavity therein, and a second filter unit 134 filled with a filtering material. The filtering material may include a cellulose-based material (e.g., acetate, paper, etc.).

[0044] In the present invention, the "segment wrapper 140" may be any one or more selected from the group consisting of the medium-containing portion wrapper 142, the moisturizing agent-containing portion wrapper 144, the first filter portion wrapper 146, and the second filter portion wrapper 148. The segment wrapper 140 may be a waterproof paper having water resistance, an oil-resistant paper having oil resistance, a water-resistant and oil-resistant paper having water and oil resistance, or a paper coated on the inside with a material having water and / or oil resistance. The segment wrapper 140 of the present invention may contain aluminum having waterproof and heat resistance characteristics, and the aluminum may be located between the outer wrapping paper and the segment when the segment wrapper is composed of a double-layered paper, and may be located between the outer wrapping paper and the inner wrapping paper when the segment wrapper is composed of a triple-layered paper. In this case, the outer wrapping paper and the inner wrapping paper may be 100% wood pulp. Considering the induction heating characteristics, it is preferable to apply a triple-layered paper containing aluminum to the medium-containing portion wrapper 142.

[0045] In order to measure the physical properties, analyze the aerosol components, perform sensory evaluation, and measure the medium containing section temperature of a smoking article according to one embodiment of the present invention, a medium containing section wrapper 142 was manufactured as shown in Table 1 below, and a smoking article including the medium containing section wrapper 142 was manufactured as shown in Table 2 below.

[0046] [Table 1]

[0047] The media containment wrapper 142 of the present invention is comprised of a triple layer paper, of which the outer wrapper 1422 and inner wrapper 1426 have a thickness of 35 μm and a basis weight of 16 gsm, and the middle wrapper 1424 has a basis weight of 54.2 gsm and contains 20 μm aluminum (FIG. 2).

[0048] For comparison, a double-wrapped control was prepared as the media container wrapper, which was composed of two wrappers, the outer wrapper having a thickness of 44 μm and a basis weight of 35 gsm, and the middle wrapper having a basis weight of 18 gsm and containing 6.3 μm aluminum.

[0049] [Table 2]

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

[0051] [Table 3] [Table 4]

[0052] Physical measurements showed that the control and experimental groups had similar physical levels of weight, circumference, and resistance to attraction.

[0053] [Experimental Example 2. Aerosol component analysis] The aerosol components were analyzed under pack-harmonized conditions for 9 puffs using the HC (Health Canada) method, an internationally recognized analytical method for regular cigarettes. The results are shown in Table 5 below.

[0054] [Table 5]

[0055] As a result, it was confirmed that the aerosol of the experimental group contained much more total particulate matter (TPM), tar (total aerosol residue (TAR), nicotine, propylene glycol, glycerin, water, and menthol than the control group. In particular, the transfer amount of glycerin was improved by 43% and that of menthol by 33%. 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, to investigate the amount of transfer during initial inhalation, the components of the aerosol were analyzed under pack-harmonized conditions of 3 puffs using the above-mentioned HC (Health Canada) method. The results are shown in Table 6 below.

[0057] [Table 6]

[0058] Even during the initial inhalation, the transfer amounts of total particulate matter (TPM), tar (TAR), glycerin (Gly), water, and menthol were all high, with the transfer amounts of glycerin and menthol increasing by 29.5% and 15.8%, respectively.

[0059] [Experimental Example 3. Sensory Evaluation] The smoking article was evaluated for heat, initial aerosol volume, total aerosol volume, menthol strength, irritation, menthol persistence, and overall tobacco taste. Sensory evaluation was performed by a subject with a background in sensory evaluation of smoking articles, who used a 7-point scale after about 10-14 puffs. The results are shown in Table 7 below.

[0060] [Table 7]

[0061] As a result, the initial aerosol amount, total aerosol amount, menthol strength, menthol persistence, and overall tobacco taste of the smoking article were all improved, and it was confirmed that there were statistically significant differences between the two groups, especially in the initial aerosol amount, total aerosol amount, menthol strength, menthol persistence, and overall tobacco taste.

[0062] 3 and 4 relate to an embodiment in which a smoking article 100 is used that includes a media containment wrapper 142 constructed from an aluminum-containing tri-ply paper.

[0063] FIG. 3 is a schematic diagram of an aerosol generating device 200 according to one embodiment.

[0064] 3, the aerosol generating device 200 includes an elongated cavity 210 that accommodates the smoking article 100, a heater 220, and a control unit 230. The control unit 230 is electrically connected to the heater 220 to control the temperature for heating the smoking article 100. The aerosol generating device 200 may further include a battery 240 that supplies power in the process of generating an aerosol.

[0065] FIG. 4 is a schematic diagram of an aerosol generating system 10 in which a smoking article 100 and an aerosol generating device 200 according to one embodiment are coupled together.

[0066] 4, the aerosol generating system 10 can include a smoking article 100 and an aerosol generating device 200. The smoking article 100 can be fitted into an elongated cavity 210 of the aerosol generating device 200, and when the smoking article 100 is fitted into the aerosol generating device 200, the heater 220 can heat at least the whole or part of the medium containing portion 110 and the humectant containing portion 120 of the smoking article 100, preferably the downstream of the humectant containing portion 120 and the upstream of the medium containing portion 110.

[0067] Specifically, in a smoking article, the length of the moisturizer containing section 120 may be 10 mm, the length of the medium containing section 110 may be 12 mm, the length of the first filter section 132 may be 12 mm, and the length of the second filter section 134 may be 14 mm, and in this case, the heater 220 may heat 7 mm downstream of the moisturizer containing section 120 and 7 mm upstream of the medium containing section 110.

[0068] [Experimental Example 4. Temperature measurement of medium storage section] The temperatures of the heated and unheated portions of the medium-containing portion 110 of the smoking article according to one embodiment of the present invention were measured. The heated portion was the medium-containing portion located 33 mm from the mouth end (ME) ((i) in FIG. 4), and the unheated portion was the medium-containing portion located 28 mm from the mouth end (ME) ((ii) in FIG. 4). The results are shown in Table 8 and FIG. 5.

[0069] [Table 8]

[0070] The medium-containing unit of the present invention not only maintains the temperature of the heated portion at about 200° C., but also maximizes the heat transfer efficiency and increases the overall temperature of the unheated portion, thereby increasing the amount of atomization of the smoking article.

[0071] As described above, although the embodiments have been described with reference to limited drawings, those having ordinary skill in the art may apply various technical modifications and variations based on the above. For example, the described techniques may be performed in a different order than described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a different manner than described, or may be replaced or substituted by other components or equivalents, and still achieve appropriate results.
