[0039] FIG. 1 is a diagram showing a smoking article according to one embodiment.

[0040] 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.

[0041] 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.

[0042] In the present invention, the "medium receiving section 110" can be filled with a plurality of tobacco sheets 112, and the plurality of tobacco sheets 112 are manufactured using base paper that is wider, has a lower basis weight, and is thinner than the base paper used in the medium receiving section of existing smoking articles, thereby providing a smoking article with much reduced resistance to drawing.

[0043] More specifically, the tobacco sheet of the present invention may have a basis weight of 20 to 50 gsm, preferably 35 gsm, and if the basis weight is higher than this, the paper thickness is large and the crimping shape is insufficient, and if the basis weight is too low, the paper thickness is thin and the paper is easily torn, making it difficult to form a filter rod. Also, the tobacco sheet of the present invention may have a thickness of 50 to 100 μm, preferably 85 μm.

[0044] The tobacco sheet of the present invention may have a paper width of 200 to 250 mm, preferably 220 mm. If the paper width is wider than this, it will be necessary to improve the filter equipment, such as the size of the bobbin, the crimping device, and the overall manufacturing equipment, while if the paper width is too narrow, it will be very difficult to form a filter rod, since a certain amount of paper needs to be filled within the filter circumference.

[0045] The physical properties of the tobacco sheet base paper used in the present invention are shown in Table 1 below.

[0046] [Table 1]

[0047] The tobacco sheets 112 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.

[0048] The length of the medium-receiving portion 110 may be 10-14 mm, preferably 12 mm, and the tobacco sheet may contain 1-30 mg / 12 mm of glycerin, preferably 20 mg / 12 mm of glycerin. If the amount of glycerin is too small, the amount of atomization is insufficient, and if the amount is too large, the filter flocks may become wet, resulting in insufficient manufacturing workability and a problem of the suction resistance increasing more than the target level.

[0049] The medium receiving portion 110 may further contain other additives such as additional moisturizers, flavorings, and / or organic acids. The additional moisturizers may be ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or oleyl alcohol, and the flavorings 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 are not limited thereto.

[0050] 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.

[0051] 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.).

[0052] 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 2 below.

[0053] [Table 2]

[0054] [Experimental Example 1. Measurement of suction resistance] First, the suction resistance of the medium storage section manufactured from the basis weight down-facing base paper was measured, and the results are shown in Table 3.

[0055] [Table 3]

[0056] A medium containing section made from paper clips was used as the control group, and the EPD (encapsulated pressure drop) was compared. The control group had an EPD of 93mmH2O immediately after production and 95mmH2O after conditioning, while the experimental groups were measured at 58mmH2O and 60mmH2O, respectively, which was approximately 40% lower than this.

[0057] The results of measuring the drawing resistance of the smoking article including the medium containing portion are shown in Table 4.

[0058] [Table 4]

[0059] A smoking article containing a medium containing section made from paper clips was used as the control group, and a comparison was made between UPDs (unencapsulated pressure drops) and EPDs (encapsulated pressure drops). The control group had a UPD of 58.5mmH2O and an EPD of 114.6mmH2O, while the experimental groups had UPDs of 53.4mmH2O and EPDs of 103.8mmH2O, respectively, showing significantly reduced values.

[0060] [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.

[0061] [Table 5]

[0062] As a result of designing the inhalation resistance of the medium container downward, 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 nicotine was improved by 11%, glycerin by 16%, and menthol by 26%. This suggests that the smoking article of the present invention has a rich atomization amount and excellent taste and aroma based on the reduced inhalation resistance.

[0063] On the other hand, when menthol or other flavorings were added to the tobacco medium in the medium housing of a smoking article using a transfer jet nozzle system (TJNS), the EPD suction resistance of the filter rod increased to the 200 mmH2O level, and the amount of glycerin transferred decreased rapidly.

[0064] [Experimental Example 3. Sensory Evaluation] The smoking articles, including the control group (clip paper) and the experimental group (basis weight down-facing base paper), were evaluated for atomization amount, inhalation, smoking taste strength, menthol strength, menthol irritation, flavor harmony, and overall satisfaction. The sensory evaluation was performed by a specialist with experience in sensory evaluation in the smoking article field, who measured the amount of atomization, inhalation, and overall satisfaction after about 10 to 14 puffs using a 7-point rating system. The results are shown in Table 6 below.

[0065] [Table 6]

[0066] As a result, the amount of atomization, inhalation, menthol strength, menthol pungency, harmonious taste, and overall satisfaction of the smoking article were all improved, and it was confirmed that there were statistically significant differences between the two groups, especially in the amount of atomization, menthol strength, harmonious taste, and overall satisfaction.

[0067] 2 and 3 relate to an embodiment in which a smoking article 100 is used that includes a medium-containing section 110 manufactured from a base paper having a basis weight lower than that of an existing base paper.

[0068] FIG. 2 is a schematic diagram of an aerosol generating device 200 according to one embodiment.

[0069] 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.

[0070] 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.

[0071] 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 into an elongated cavity 210 of the aerosol generating device 200, and a heater 220 can heat at least all or a portion of the medium containing portion 110 and the humectant containing portion 120 of the smoking article 100 when the smoking article 100 is fitted into the aerosol generating device 200.

[0072] 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.
