Abstract

The present application provides an aerosol generating article capsule, a method of manufacturing the same, and an aerosol generating article including the same, wherein the aerosol generating article capsule includes a specific combination of a cooling agent A, a cooling agent B, and a cooling agent C.

Description

Technical Field

[0001] This invention relates to capsules for aerosol-generating articles comprising a cooling block, and aerosol-generating articles comprising the capsule. Background Technology

[0002] Currently, some cooling agents are used alone in shaving foam, toothpaste, mouthwash, and food, but flavored cooling blocks with cooling agents have not yet replaced menthol in aerosol-generating products.

[0003] On the other hand, menthol accounts for a larger proportion of current aerosol-generated products compared to other flavoring substances. Only products that possess the key characteristics of menthol or have differences and diversity compared to existing menthol products can be competitive. Developing menthol alternatives and product application technologies are urgent issues to be addressed in order to achieve characteristics similar to menthol, thereby maintaining the product's existing competitiveness and continuing to provide convenience to consumers.

[0004] On the other hand, the sensory characteristics of menthol can be divided into primary and secondary characteristics. The primary characteristics include cooling (body), non-drying and refreshing (fresh), and minty aroma; the secondary characteristics include herbal, green, and earthy aromas.

[0005] It is difficult to achieve the complex sensory properties of menthol by using certain specific cooling agents alone. Similar properties to menthol can only be reproduced by mixing the characteristics of different cooling agents. Therefore, it is necessary to develop relevant formulations. Summary of the Invention

[0006] The problem the invention aims to solve

[0007] In this context, in order to overcome the current status and / or limitations of the prior art, the present invention aims to provide capsules for aerosol generation articles and aerosol generation articles including the capsules by utilizing a cooling block comprising a specific combination of cooling agents.

[0008] However, the problems to be solved by the present invention are not limited to the above description, and those skilled in the art will clearly understand other unmentioned problems through the following description.

[0018] The embodiments will now be described in detail with reference to the accompanying drawings. It should be understood that various modifications can be made to the embodiments, and the scope of this application is not limited to the embodiments described below. All modifications to the embodiments, their equivalents, and even their substitutes are within the scope of this invention.

[0019] The terminology used in the embodiments is for illustrative purposes only and is not intended to limit the scope. Unless otherwise specified in the content, a single type expression includes multiple type expressions. In this specification, terms such as "comprising" or "having" are used to express the presence of the features, numbers, steps, operations, constituent elements, accessories, or combinations thereof described in the specification, and do not exclude the possibility of the presence or additional addition of one or more other features, numbers, steps, operations, constituent elements, accessories, or combinations thereof.

[0020] Unless otherwise defined, all terms used herein, including technical or scientific terms, shall have their ordinary meanings as understood by one of ordinary skill in the art. Terms commonly used, such as those defined in dictionaries, shall be understood as having their meanings in the relevant technical context and shall not be interpreted as idealized or overly formalized meanings unless explicitly defined in this specification.

[0021] Furthermore, in the description with reference to the accompanying drawings, the same reference numerals are used for the same constituent elements regardless of the drawing numbers, and repeated descriptions are omitted. In describing the embodiments, detailed descriptions of relevant well-known technologies are omitted when it is determined that such detailed descriptions would unnecessarily obscure the embodiments.

[0022] Furthermore, when describing the constituent elements of the embodiments, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish one constituent element from other constituent elements and are not used to limit the nature or order of the corresponding constituent elements.

[0023] When a constituent element has a common function with a constituent element of one embodiment, the same name is used in descriptions in other embodiments. Unless counterexamples are mentioned, the description of one embodiment is applicable to other embodiments, and detailed descriptions of repeated content may be omitted.

[0024] Throughout this specification, "aerosol-generating article" can refer to any article capable of generating aerosols, including combustible aerosol-generating articles such as cigarettes and cigars, as well as heated non-combustible aerosol-generating articles. Aerosol-generating articles may include aerosol-generating substances or aerosol-forming matrices. Furthermore, aerosol-generating articles may include solid substances (cigarette media) based on tobacco raw materials such as tobacco sheets, shredded tobacco, and reconstituted tobacco. Aerosol-generating articles may include volatile compounds.

[0025] Furthermore, throughout the instructions, "upstream" or "upstream direction" refers to the direction away from the user's mouth when inhaling the aerosol-generating product, while "downstream" or "downstream direction" refers to the direction towards the user's mouth when inhaling the aerosol-generating product. For example, in Figure 1 In the combustion-type aerosol generating article 100 shown, the tobacco medium section 120 is located upstream of or in the upstream direction of the filter rod section 110.

[0026] Furthermore, in this specification, the aerosol generating article 100 is exemplified by selecting one of the following non-combustible (heated) cigarettes used with an aerosol generating device (not shown), such as a combustible cigarette or an electronic cigarette. However, the present invention is not limited thereto and may include all of the above concepts.

[0027] Additionally, in this specification, "cooling block" can refer to a flavoring or cooling agent composition consisting of a specific combination of cooling agents developed herein, used to provide a cooling sensation, freshness, and minty flavor similar to those of menthol.

[0028] According to an embodiment of the present invention, a capsule for aerosol-generated products is provided, relating to a capsule for aerosol-generated products comprising a cooling block, wherein the cooling block comprises: cooling agent A, selected from at least one of WS-3, WS-5, WS-23 and menthyl lactate; cooling agent B, selected from at least one of isopulegol, 4-terpineol, menthone and menthyl acetate; and cooling agent C, selected from at least one of cis-3-hexenol, hexyl alcohol, 1,4-cineol and eucalyptol.

[0029] The cooling agent A contained in the cooling block is a base cooling agent with relatively low volatility, which can impart body and persistence to the aroma. Specific types of cooling agent A include WS-3 (N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide), WS-23 (N,2,3-trimethyl-2-isopropylbutanamide), and menthyl lactate, etc., and combinations thereof may also be included as needed.

[0030] WS-3 provides a long-lasting cooling sensation, while WS-5 offers a similar cooling sensation to WS-3 but may release unpleasant odors such as saltiness. Additionally, menthyl lactate can provide a certain level of cooling sensation and maintain its duration, while WS-23 can also provide a cooling sensation, but to a lesser degree than menthyl lactate. Compared to WS-23, menthyl lactate can provide a fresher or milder sensation.

[0031] In addition, when used with WS-3, the lactic acid menthol can neutralize the spiciness of WS-3. Taking all factors into consideration, in order to provide a cooling, lasting, refreshing and mild sensation, it is preferable to use WS-3 and lactic acid menthol in combination.

[0032] On the other hand, the content of the low-volatility cooling agent A contained in the cooling block of the capsule according to an embodiment of the present invention may be from 10% to 60% by weight, preferably from 15% to 55% by weight, and more preferably from 20% to 50% by weight.

[0033] When the content of cooling agent A exceeds the upper limit, it will disrupt the overall aroma balance (the characteristics of cooling and minty, the balance of freshness and herbal), resulting in an overly strong aroma that suppresses the aroma of cooling agent B as the middle note and cooling agent C as the top note, leading to a negative effect; while when it is below the lower limit, due to the insufficient amount of cooling agent A, the cooling sensation will be reduced, disrupting the overall balance.

[0034] Meanwhile, the content of WS-3 in the cooling agent A can be from 5% to 20% by weight of the total weight of the cooling block, preferably from 10% to 15% by weight. In addition, the content of menthyl lactate can be from 5% to 40% by weight, more preferably from 30% to 40% by weight.

[0035] When the contents of WS-3 and menthyl lactate are within the above-mentioned ideal range, as described above, the best effect is exhibited in terms of overall performance, such as cooling sensation, duration, refreshing sensation, and mildness. The differences in effect based on different ranges will be explained in detail through the following examples and comparative examples.

[0036] The cooling agent B contained in the cooling block is a middle-tone cooling agent that is a moderately volatile cooling agent that enhances the aroma characteristics. The specific types of cooling agent B include isopulegol, 4-terpineol, menthone, and menthyl acetate, and combinations thereof may also be included as needed.

[0037] Among the types of cooling agents B, menthone imparts a minty flavor, while menthyl acetate is responsible for harmonizing the base, middle, and top notes to prevent the individual characteristics of the base cooling agent A and the top cooling agent C (described later) from becoming too prominent. Furthermore, isoprene can create an earthy aroma, while 4-terpineol can enhance the harshness. However, isoprene is expensive, and the harshness of 4-terpineol can have a negative impact on smokers. Therefore, considering that the purpose of this invention is to achieve properties most similar to menthol, a combination of menthone and menthyl acetate is preferred.

[0038] On the other hand, the content of moderately volatile neutralizing agent B contained in the cooling block of the capsule according to an embodiment of the present invention may be from 5% to 50% by weight, preferably from 10% to 45% by weight, and more preferably from 15% to 40% by weight.

[0039] When the content of cooling agent B exceeds the above-mentioned upper limit, it will affect the connection between cooling agent A, which is the base note, and cooling agent C, which is the top note, affecting the overall aroma balance and limiting the unique aroma of cooling agent C, which is the top note; when it is below the above range, the insufficient content of cooling agent B will reduce the minty flavor and affect the overall balance.

[0040] Furthermore, the menthol content in the cooling agent B is 10% to 30% by weight of the total weight of the cooling block, preferably 15% to 25% by weight. Additionally, the content of menthyl acetate can be 5% to 20% by weight, more preferably 2% to 8% by weight.

[0041] When the contents of menthone and menthyl acetate are within the above-mentioned preferred range, they exhibit good effects in terms of aroma intensity and overall balance, which can be confirmed by comparing Examples 1 to 2 and Comparative Example 2. Furthermore, they also have a minty flavor similar to menthol, and the cooling characteristics of the top, middle and base notes are integrated to form an overall balance.

[0042] The cooling agent C contained in the cooling block is a fast-evaporating top cooling agent with aroma intensity, uniqueness, and dispersibility. Specific types of cooling agent C include cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol, and combinations thereof may also be included as needed.

[0043] Among the types of cooling agent C, cis-3-hexenol can provide a grassy, ​​green aroma, while hexanol can further impart an oily feel. Additionally, eucalyptol enhances the minty and cooling sensation, imparting a natural, herbal, and fresh aroma; while 1,4-cineole has herbal, grassy, ​​fresh, and light aroma characteristics, but its overall harmony is not as good as eucalyptol. Therefore, considering these aspects, eucalyptol is preferred as the cooling agent C.

[0044] On the other hand, the content of the fast-evaporating pre-cooling agent C contained in the cooling block of the capsule according to an embodiment of the present invention can be greater than 0% by weight and less than 40% by weight, preferably 0.5% by weight to 10% by weight, or 0.5% by weight to 5% by weight.

[0045] If the content of cooling agent C exceeds the above-mentioned upper limit, it may be impossible to achieve the natural aroma characteristics, resulting in an artificial, overly strong aroma, and it may also disrupt the balance with the middle-note cooling agent B. On the other hand, if cooling agent C is not included, it may be impossible to convey the uniqueness of the spices, resulting in a lack of freshness and pleasure due to the reduced completeness of the aroma.

[0046] The above results can also be confirmed by the sensory evaluation between Examples 1 and 2 described later and Comparative Example 3 which does not contain eucalyptol. It can be seen that even if the content of cooling agent C in the cooling block is very small, it has a great influence on the cooling sensation of menthol, the enhancement of aroma intensity and the refreshing aftertaste.

[0047] On the other hand, in addition to the cooling agents A, B, and C described in detail above, the cooling block for aerosol-generated products according to an embodiment of the present invention may also include a solvent for mixing the above-described reagents. In this case, the solvent used may include at least one selected from the group consisting of alcohol, propylene glycol, and glycerol, and is preferably alcohol.

[0048] At this point, the solvent content contained in the chilled food block may be less than 50% by weight of the total weight of the chilled food block, preferably about 15% to 30% by weight.

[0049] In this way, the balance of cooling agents A, B, and C can be maintained by adjusting the amount of solvent contained in the cooling block, thus maintaining its function as a substitute for menthol while only adjusting the aroma intensity.

[0050] Meanwhile, the cooling block can be prepared according to the following steps: step a, preparing raw materials for cooling agent A, cooling agent B, and cooling agent C; and step b, mixing cooling agent A, cooling agent B, and cooling agent C with a solvent; at this time, cooling agent A is at least one selected from the group consisting of WS-3, WS-5, WS-23, and menthyl lactate; cooling agent B is at least one selected from the group consisting of isopulegol, 4-terpineol, menthone, and menthyl acetate; and cooling agent C is at least one selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol, and eucalyptol.

[0051] In addition, the solvent used in step b is basically the same as the solvents described above, and is preferably alcohol.

[0052] According to an embodiment of the present invention, a capsule including a cooling block can be used in an aerosol-generating article, which may be a smoking article including a tobacco medium portion, a filter portion, and packaging materials.

[0053] At this time, the capsule including the cooling block can be included in the filter rod section.

[0054] For example, relative to 100kg of tobacco medium (tobacco shreds), the amount of cooling block added in the capsule can be 50g to 250g, preferably 100g to 105g. When the amount of cooling block is greater than or less than the above range, the cooling block effect expected by the present invention may be reduced.

[0055] Furthermore, the filter rod portion included in the aerosol generating article can be divided into at least two segments, such as a first filter rod portion and a second filter rod portion. In this case, regardless of the arrangement position, if at least one of the at least two segments includes a capsule comprising a cooling block according to an embodiment of the present invention, it is included within the scope of the present invention. Further, such a capsule can be spherical or cylindrical, preferably having a core-shell structure, but is not limited thereto.

[0056] For example, when the capsule for the aerosol-generating product has a core-shell structure, the cooling block may be included in the core, and the shell may be a membrane material containing water, plasticizer, agar, pectin, and sodium alginate.

[0057] In addition, the tobacco medium portion typically contains tobacco material containing nicotine along with the tobacco leaf, and may further include excipients such as binders or other additives. For example, the tobacco medium contained in the tobacco medium portion of the present invention can be prepared in particulate form including tobacco substances and excipients.

[0058] In this invention, tobacco material is the substance constituting the aerosol-forming substrate, and may be tobacco leaves, tobacco stems, dust generated during tobacco processing, and / or tobacco leaf strips. The tobacco leaves may be selected from at least one of yellow tobacco leaves, burley tobacco leaves, oriental tobacco leaves, cigar tobacco leaves, and flue-cured tobacco leaves, but are not limited thereto.

[0059] At the same time, such as Figure 1 As shown in the (combustion-type aerosol generating article), the packaging material according to an embodiment of the present invention may include packaging material that wraps each component of the aerosol generating article, and may be divided into tobacco medium portion packaging material 120a that wraps the tobacco medium portion, filter rod portion packaging material (filter rod forming paper) 110a that wraps the filter rod, etc. Furthermore, as described above, when the filter rod portion is composed of multiple segments, packaging material that wraps each segment may be included. Additionally, to securely connect the tobacco medium portion and the filter rod portion, a splicing paper 130 may be included that wraps a portion of the tobacco medium portion and the filter rod portion. Moreover, to maintain the overall shape of the aerosol generating article, an outer packaging that wraps the entire tobacco medium portion and filter rod portion may be included on the outermost side of the aerosol generating article.

[0060] Optionally, the tipping paper used to connect the tobacco medium and the filter rod may have at least one perforation formed circumferentially to allow external air to flow in or internal gas to flow out, thereby achieving an air dilution rate of the cigarette and controlling the amount of transfer of mainstream smoke components.

[0061] Furthermore, according to an embodiment of the present invention, the capsule including the cooling block can also be included in, for example... Figure 2 The non-combustible aerosol generating products shown.

[0062] According to another aspect of the present invention, a method for preparing a capsule for an aerosol-generating product comprising a cooling block is provided, comprising the following steps: step S1, preparing a membrane material; step S2, preparing a capsule using the membrane material and the cooling block; step S3, hardening the capsule; and step S4, drying the capsule; wherein the cooling block comprises: cooling agent A, at least one selected from the group consisting of WS-3, WS-5, WS-23 and menthyl lactate; cooling agent B, at least one selected from the group consisting of isopulegol, 4-terpineol, menthone and menthyl acetate; and cooling agent C, at least one selected from the group consisting of cis-3-hexenol, hexyl alcohol, 1,4-cineol and eucalyptol.

[0063] Step S1 in preparing the membrane material of this embodiment of the invention is the step of preparing the membrane material for wrapping the cooling block. An appropriate amount of the components for preparing the membrane material is weighed and dissolved to form the membrane material. At this time, the components forming the membrane material can be agar, pectin, sodium alginate, and glycerol as a plasticizer. These components can be dissolved in water to form the membrane material. The viscosity of the membrane material prepared at this time is, for example, 400 to 700 cp (centipoise), preferably 500 to 650 cps.

[0064] The functions of each component in the membrane material are as follows: First, agar acts as a hardening agent according to temperature, allowing it to form a capsule shape at the initial stage of molding. Pectin is an intermediate regulator between agar and sodium alginate, acting to adjust the hardness of agar and bind calcium ions to sodium alginate, thus forming the initial capsule shape. It also improves stability and hygroscopicity, which is beneficial for film formation.

[0065] The sodium alginate hardens upon contact with calcium ions, thereby controlling the capsule's hardness and forming a film. It can also improve moisture absorption stability based on ion hardening.

[0066] Glycerin is a plasticizer that helps in capsule shaping and imparts elasticity. While increasing the amount of glycerin increases capsule elasticity, glycerin itself is highly hygroscopic, which may reduce hygroscopic stability in the long run. Conversely, insufficient glycerin reduces capsule elasticity, making it more susceptible to damage from external factors. Therefore, mixing an appropriate amount of glycerin is crucial.

[0067] For example, the membrane material, in addition to water and glycerol, may consist of 45 to 55 vol% agar, 35 to 45 vol% pectin and 5 to 15 vol% sodium alginate.

[0068] Meanwhile, step S2 of preparing the capsule involves wrapping the cooling block with the membrane material to prepare the capsule. The specific shape of the capsule is as described above.

[0069] Furthermore, the capsules prepared via step S2 can undergo a hardening step S3. At this point, an ethanol preparation solution can be used to harden the capsules by immersing them in a 70% to 100% ethanol preparation solution for approximately 3 to 5 minutes.

[0070] After the hardening step S3, step S4 can be performed to dry the capsule using specific temperature, humidity, airflow or rotation speed. After drying, the capsules can be placed in batches on a drying plate for further drying, thereby finally completing the capsules for aerosol generation products.

[0071] The structure and effects of the present invention will be described in more detail below with reference to embodiments and comparative examples. However, these embodiments are only used to illustrate the present invention in more detail, and the scope of the present invention is not limited thereto.

[0072] Example

[0073] (1) Preparation Example 1: Preparation of Cooling Blocks

[0074] Example 1

[0075] To prepare a cooling block according to an embodiment of the present invention, powdered WS-3 and menthyl lactate, as well as liquid menthone, menthyl acetate, and eucalyptol were prepared as flavoring ingredients. The prepared WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol were mixed with alcohol as a solvent and stirred for a period of time to allow the flavoring ingredients to fully dissolve in the alcohol.

[0076] At this point, the added raw materials and the alcohol content are shown in Table 1 below.

[0077] Example 2

[0078] Except for adjusting the WS-3 content in the cooling agent to 25% by weight and the menthone content to 10% by weight, the cooling block was prepared in the same manner as in Example 1.

[0079] Comparative Example 1

[0080] Except that WS-23 was used instead of WS-3 dissolved in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of WS-23 added this time was 15% by weight of the total weight of the prepared cooling blocks.

[0081] Comparative Example 2

[0082] Except that 4-terpineol was used instead of menthone to dissolve in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of 4-terpineol added this time was 20% by weight of the total weight of the prepared cooling blocks.

[0083] Comparative Example 3

[0084] Except that 1,4-cineol was used instead of eucalyptol and dissolved in alcohol, the cooling blocks were prepared in the same manner as in Example 1. The amount of 1,4-cineol added this time was 2% by weight of the total weight of the prepared cooling blocks.

[0085] The types and contents of cooling agents in the cooling blocks prepared in Examples 1 to 2 and Comparative Examples 1 to 3 are summarized in Table 1 below.

[0086] Table 1

[0087]

[0088] (All values ​​in Table 1 are in weight percent)

[0089] (2) Preparation Example 2: Preparation of capsules containing cooling blocks

[0090] A membrane material was prepared by dissolving 50 vol% agar, 40 vol% pectin, and 10 vol% sodium alginate in glycerol and water. The cooling block prepared in Example 1 was then placed inside the membrane material, and spherical capsules were prepared using a capsule preparation apparatus. The spherical capsules were then immersed in an ethanol preparation solution prepared by mixing distilled water and ethanol in a 7:3 volume ratio for 5 minutes to harden, and then dried to prepare capsules containing the cooling block.

[0091] (3) Experimental Example 1: Sensory evaluation of the prepared chilled snack blocks

[0092] An evaluation team of 16 internal personnel from the Research and Development Department of Korea Tobacco & Ginseng Corporation (KT&G R&D) evaluated the aerosol-generating products, including those from Examples 1-2 and Comparative Examples 1-3, which incorporated capsules containing cooling blocks into the filter section. The evaluations assessed the flavor intensity, menthol coolness, smoothness of swallowing, aroma intensity, overall balance, refreshing aftertaste, and overall satisfaction, with a maximum score of 9 points. The average evaluation results are shown in Table 2 below.

[0093] Table 2

[0094]

[0095] Referring to Table 2, the evaluation results of Examples 1 and 2, which included WS-3, menthyl lactate, menthone, menthyl acetate, and eucalyptol, showed better results in terms of aroma intensity, menthol coolness, aroma intensity, overall balance, refreshing aftertaste, and overall satisfaction compared to Comparative Examples 1 to 3, which lacked WS-3, menthone, and eucalyptol, respectively.

[0096] More specifically, Comparative Example 1, which lacked WS-3, performed poorly in several evaluation categories, particularly in aroma intensity and aftertaste freshness; Comparative Example 2, which lacked menthol, performed poorly in aroma intensity and overall balance. Furthermore, Comparative Example 3, which lacked eucalyptol, scored lower than the examples in menthol coolness, aroma intensity, overall balance, and aftertaste freshness.

[0097] That is, it can be seen that smokers' overall satisfaction with Examples 1 and 2 is higher than that with Comparative Examples 1 to 3.

[0098] On the other hand, when comparing Examples 1 and 2 with different contents of WS-3 and menthone, Example 2, which added excessive WS-3 or a small amount of menthone, was slightly inferior in terms of menthol coolness, smoothness of swallowing, aroma intensity, overall balance and refreshing aftertaste, and was lower than Example 1 in terms of overall satisfaction.

[0099] (4) Experiment Example 2: Sensory evaluation compared with existing tobacco

[0100] A comparison of aerosol-generating products including the capsules of Preparation Example 2 with existing Korean Esse Change 1mg.

[0101] The capsule containing the cooling block prepared in Preparation Example 2 was applied to an aerosol-generated product.

[0102] Subsequently, an evaluation team of 13 internal personnel from KT&G R&D will be formed. The team members will evaluate the aerosol-generated product, consisting of a capsule containing a cooling block as described in Preparation Example 2, after inhaling an existing Esse Illusion 1mg (a test product, in which menthol was partially mixed into the flavoring during the preparation of Esse Illusion 1mg). The evaluation will assess the flavor intensity, menthol coolness, smoothness of swallowing, aroma intensity, overall balance, refreshing aftertaste, and satisfaction, with a maximum score of 9 points. The average evaluation results are shown in Table 3 below.

[0103] Table 3

[0104]

[0105] A comparison was made between the aerosol-generating product, including the capsule from Preparation Example 2, and the conventional Essehana 1mg.

[0106] A 16-person evaluation team from KT&G R&D conducted evaluations using the same method described above. The team members inhaled an aerosol product containing 1 mg of Essehana (a test product, prepared without mixing menthol and cooling bolus in the two flavoring processes) and a capsule containing the cooling bolus from Preparation Example 2. The average evaluation results are shown in Table 4 below.

[0107] Table 4

[0108]

[0109] A comparison was made between the aerosol-generated product containing the capsules of Preparation Example 2 and the existing Raison French Black product.

[0110] An evaluation team of 16 internal personnel from KT&G R&D was formed. The team members evaluated the products using the same method described above after inhaling both the existing Raison French Black capsules and the capsule containing the cooling block from Preparation Example 2. The average evaluation results are shown in Table 5 below.

[0111] Table 5

[0112]

[0113] As can be seen from the results of the test example 2, the aerosol-generated product of the present invention, which includes capsules containing cooling blocks, is superior to existing aerosol-generated products such as Esse Magic 1mg, regular Esse Magic 1mg, and Eiffel Tower Cat red wine burst beads in terms of menthol cooling sensation, refreshing aftertaste, and overall satisfaction. The cooling blocks can supplement the taste acceptance and satisfaction of existing menthol products and better reflect the multi-sensory characteristics.

[0114] In summary, the embodiments have been described with reference to the limited accompanying drawings. Those skilled in the art can make various modifications and variations based on the description. For example, appropriate results can be obtained by performing the described techniques in a different sequence than the described methods, and / or by combining or integrating the described constituent elements in a different manner than the described methods, or by replacing or substituting them with other constituent elements or equivalents.

[0115] Therefore, other embodiments, other implementations, and equivalents of the invention application are all within the scope of the appended invention application.
