[0040] In the present invention, the "medium" may include, but is not necessarily limited to, a solid substance based on tobacco raw materials such as tabular tobacco, shredded tobacco, or reconstituted tobacco, and / or a liquid composition based on glycerin, propylene glycol, nicotine, menthol, caffeine, GABA, taurine, vitamins, or various flavoring agents.

[0041] In the present invention, the "medium-containing section 110" may be filled with a plurality of tobacco sheets, tobacco shreds, or tobacco granules. The tobacco shreds 112 refer to a solid material based on tobacco raw material, and the medium-containing section may be formed by combining a plurality of tobacco shreds in the same direction or randomly, and preferably arranged in a straight line within the medium-containing section to ensure an airflow path and improve the amount of atomization.

[0042] The tobacco shred 112 may include, but is not limited to, ordinary shred, puffed shred, slurry leaf, and combinations thereof. The ordinary shred may include, but is not limited to, flue-cured, burley, or oriental tobacco leaves. The width of the ordinary shred may be 1.3 to 1.6 mm, which is longer than the conventional 0.9 mm, and is preferably 1.4 mm. The puffed shred refers to shred obtained by puffing ordinary shred, and may be puffed using various types of solvents or gases such as organic solvents, carbon dioxide, argon, and nitrogen, or may be puffed by absorbing moisture from ordinary shred to increase its volume, then rapidly freezing it, sublimating the moisture, and drying it to puff it, but is not limited to these. The slurry plate is produced by cutting a plate sheet produced using a slurry into small pieces, and the slurry can be produced by grinding tobacco raw material, mixing an aerosol generating substance, flavoring liquid, binder (e.g., guar gum, xanthan gum, carboxymethyl cellulose, etc.), water, etc., and preferably contains 23 to 27 parts by weight of glycerin. The slurry plate of the present invention contains a high content of glycerin, which can help improve the amount of atomization.

[0043] The tobacco shreds of the present invention may contain 50 to 70 parts by weight of regular shreds, 10 to 30 parts by weight of expanded shreds, and 10 to 30 parts by weight of slurry leaves, and preferably contain 60 parts by weight of regular shreds, 20 parts by weight of expanded shreds, and 20 parts by weight of slurry leaves.

[0044] 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.

[0046] 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.).

[0047] In the present invention, the "segment wrapper 140" may be any one or more selected from the group consisting of the medium-containing section wrapper 142, the moisturizing agent-containing section wrapper 144, the first filter section wrapper 146, and the second filter section 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 substance 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. The triple-layered paper may contain aluminum having a thickness of 15 to 25 μm, preferably 20 μm. In this case, the outer wrapping paper and the inner wrapping paper may be 100% wood pulp. A tri-ply paper containing aluminum is preferably applied to the media containment portion wrapper 142 for its induction heating properties.

[0048] [Experimental Example 1. Experimental results depending on the ratio of expanded shredded grass] In order to measure the drawing resistance, analyze the aerosol components, and perform a sensory evaluation of the smoking article according to one embodiment of the present invention, the smoking article was manufactured as shown in the following Table 1. At this time, the cigarette rod was divided into 6 equal parts and manufactured so that they were positioned in the medium housing part inside the stick.

[0049] [Table 1]

[0050] The medium containing 100 parts by weight of ordinary shredded herb was used as the control group, and the experimental group containing 20 parts by weight of expanded shredded herb was compared in physical properties. The results are shown in Table 2 below.

[0051] [Table 2]

[0052] As a result, by applying expanded shredded grass with good swelling properties, the weight of the shredded grass decreased when the same suction resistance was applied.

[0053] In addition, the components of the aerosol were analyzed under pack-harmonized conditions for 9 puffs using the HC (Health Canada) method, which is an internationally recognized analytical method for regular cigarettes. The results are shown in Table 3 below. [Table 3]

[0054] As a result of increasing the proportion of expanded shredded grass, the aerosol of the experimental group showed a 16% increase in glycerin transfer rate compared to the aerosol of the control group, suggesting that the smoking article of the present invention has a rich atomization rate and excellent taste and aroma.

[0055] [Experimental Example 2. Experimental results depending on the ratio of slurry plate leaves] In order to measure the drawing resistance, analyze the aerosol components, and perform a sensory evaluation of the smoking article according to one embodiment of the present invention, the smoking article was manufactured as shown in Table 4 below.

[0056] [Table 4]

[0057] The medium containing 80 parts by weight of regular shredded herb and 20 parts by weight of expanded shredded herb was used as the control group, and the physical properties of the experimental groups containing 60 parts by weight of regular shredded herb, 20 parts by weight of expanded shredded herb, and 20 parts by weight of slurry leaf sheets were compared. The results are shown in Table 5 below.

[0058] [Table 5]

[0059] As a result, by applying a slurry sheet with a high specific gravity, the weight of the shredded grass increases slightly based on the application of the same suction resistance, but the amount of cigarette end loss is reduced by about 2.2 times, and the quality of manufacturing workability is greatly improved.

[0060] In addition, the components of the aerosol were analyzed under pack-harmonized conditions for 9 puffs using the HC (Health Canada) method, which is an internationally recognized analytical method for regular cigarettes. The results are shown in Table 6 below.

[0061] [Table 6]

[0062] By increasing the proportion of slurry plates, it was confirmed that the experimental aerosol contained greater amounts of total particulate matter (TPM), nicotine, propylene glycol, glycerin, and water than the control aerosol. In particular, the transfer amount of glycerin, which is an index of the amount of atomization, increased by 0.86 mg, which is a 13.5% improvement compared to the control group.

[0063] [Experimental Example 3. Experimental results for the width of general cuttings] In order to measure the drawing resistance, analyze the aerosol components, and perform a sensory evaluation of the smoking article according to one embodiment of the present invention, the smoking article was manufactured as shown in Table 7 below.

[0064] [Table 7]

[0065] The medium storage section containing 100 parts by weight of regular shredded grass with a shredded width of 1.2 mm was used as the control group, and the medium storage section containing 100 parts by weight of regular shredded grass with a shredded width of 1.4 mm was used as the experimental group. The results of comparing the physical properties of the cigarettes and sticks are shown in Table 8 below.

[0066] [Table 8]

[0067] By increasing the shredded width to 1.4mm, the drawing resistance of the medium container decreased. More specifically, in the case of cigarettes, the experimental group showed a 25.4% decrease in encapsulated pressure drop (EPD) compared to the control group. In the case of sticks, the experimental group showed a 6.4% decrease in unencapsulated pressure drop (UPD) and a 7% decrease in EPD compared to the control group.

[0068] Meanwhile, when comparing the physical properties of the shredded grass itself, in the control group, the percentage of long shredded grass pieces with a size of 1.25 mm or more was 83%, while in the experimental group, the percentage of long shredded grass pieces was 90.9%, an improvement of 9.5%. This suggests that the smoking article of the present invention has a high percentage of long shredded grass pieces, and is able to reduce the inhalation resistance when an appropriate amount is dispensed without the end of the cigarette rod falling off, improving the inhalation properties of the stick and enabling an increase in the amount of atomization. Furthermore, the smoking article of the present invention had good manufacturing quality, with the shredded grass size itself generally improving and end fall-off being improved (Table 9).

[0069] [Table 9]

[0070] In addition, the components of the aerosol were analyzed under pack-harmonized conditions for 9 puffs using the HC (Health Canada) method, which is an internationally recognized analytical method for regular cigarettes. The results are shown in Table 10 below.

[0071] [Table 10]

[0072] As a result of increasing the chopping width of ordinary shredded herbs, the experimental aerosol showed a glycerin transfer rate that was 0.48 mg, or 7.5%, higher than that of the control aerosol.

[0073] 2 and 3 relate to an embodiment in which the smoking article 100 described above is used.

[0074] FIG. 2 is a schematic diagram of an aerosol generating device 200 according to one embodiment.

[0075] 2, 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 and can control the temperature for heating the smoking article 100. The aerosol generating device 200 can further include a battery 240 that supplies power in the process of generating an aerosol.

[0076] FIG. 3 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.

[0077] 3, the aerosol generating system 10 can include a smoking article 100 and an aerosol generating device 200. The smoking article 100 can be fitted snugly into an elongated cavity 210 of the aerosol generating device 200, and when the smoking article 100 is fitted to the aerosol generating device 200, the heater 220 can heat at least the whole or a part of the medium containing portion 110 and the humectant containing portion 120 of the smoking article 100, and preferably heat a part of the humectant containing portion 120, the whole of the cut grass portion 112, and a part of the cardboard tube portion 114.

[0078] 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.
