Description

[Technical field]

[0001] The present disclosure relates to a sound-emitting flavored sheet and a smoking article including the same. More specifically, the present disclosure relates to a flavored sheet that can provide an improved smoking experience by adding not only an olfactory (or gustatory) effect but also an auditory effect to the smoking article, a smoking article including the same, and a manufacturing method thereof. [Background technology]

[0002] In order to provide smokers with an improved smoking experience, various research efforts are underway to impart auditory effects to tobacco products.

[0003] Recently, cigarettes have been proposed that generate noise every time the cigarette is shaken by putting granules or capsules into the cavity filter. However, these cigarettes have the disadvantage that the noise is difficult to generate continuously while smoking, as the sound is generated only when the filter is shaken, and the smoker must shake the filter directly.

[0004] Meanwhile, kretek cigarettes, which are widely used in Indonesia, are not the product of the above-mentioned research, but are a product that produces a burning sound while smoking. When smoking, kretek cigarettes produce a crackling sound (or kritik-kritik) as the clove substances burn, and the name "kretek" comes from this characteristic. This crackling sound adds an auditory effect when smoking, making the act of smoking a more playful act, providing smokers with an improved smoking experience. However, the unique scent of the clove substances can be repulsive to smokers, making it difficult to universally apply this to tobacco products. Summary of the Invention [Problem to be solved by the invention]

[0005] The technical problem to be solved through several embodiments of the present disclosure is to provide a flavored sheet and a manufacturing method thereof that can add not only olfactory (or gustatory) effects but also auditory effects to smoking articles.

[0024] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The advantages and features of the present disclosure, and the methods for achieving them, will be apparent from the following detailed embodiments with reference to the accompanying drawings. However, the technical idea of ​​the present disclosure is not limited to the following embodiments, and may be embodied in various different forms. However, the following embodiments are provided to complete the technical idea of ​​the present disclosure and to fully inform those skilled in the art of the present disclosure of the scope of the present disclosure, and the technical idea of ​​the present disclosure is only defined by the scope of the claims.

[0025] When adding reference symbols to components in each drawing, it should be noted that the same components are assigned the same symbols as much as possible even if they are displayed in different drawings. In addition, when describing the present disclosure, detailed descriptions of related known configurations or functions are omitted if it is determined that such descriptions may unnecessarily obscure the gist of the present disclosure.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in the sense commonly understood by those having ordinary skill in the art to which this disclosure belongs. In addition, terms defined in commonly used dictionaries are not interpreted ideally or excessively unless specifically defined. The terms used herein are intended to describe the embodiments and are not intended to limit the present disclosure. In this specification, the singular form includes the plural form unless otherwise specified in the text.

[0027] In addition, when describing components of the present disclosure, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are merely used to distinguish the components from other components, and do not limit the essence, procedure, or order of the components. When a component is described as being "coupled," "coupled," or "connected" to another component, it should be understood that the component may be directly coupled or connected to the other component, but that other components may also be "coupled," "coupled," or "connected" between each component.

[0028] As used in this disclosure, "comprises" and / or "comprising" means that a referenced component, step, operation and / or element does not exclude the presence or addition of one or more other components, steps, operations and / or elements.

[0029] We first clarify some terminology used in various embodiments of this disclosure.

[0030] In the following examples, "smoking article" may refer to any product that can be smoked or that can provide a smoking experience, whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. For example, smoking articles may include smokable products such as cigarettes, cigars, and cigarillos, etc. As another example, smoking articles may include combustible smoking articles and heated smoking articles.

[0031] In the following examples, "smoking material" may refer to a material that produces smoke and / or aerosol or is used for smoking. For example, smoking material may include tobacco material. Tobacco material may include, for example, tobacco leaf shreds, tobacco stems, or materials processed therefrom. As more specific examples, tobacco material may include ground tobacco leaves, ground reconstituted tobacco, expanded shreds, expanded midribs, and tabular leaves. However, it is not limited thereto.

[0032] In the following examples, "upstream" or "upstream direction" may mean a direction away from the mouth of the smoker, and "downstream" or "downstream direction" may mean a direction toward the mouth of the smoker. The terms upstream and downstream may be used to describe the relative positions of elements that make up a smoking article. For example, in the smoking article 100 illustrated in FIG. 1, the filter portion 120 is located downstream or downstream of the smoking material portion 110, and the smoking material portion 110 is located upstream or upstream of the filter portion 120.

[0033] In the following examples, "longitudinal direction" may mean the direction corresponding to the longitudinal axis of a smoking article.

[0034] In the following examples, "puff" refers to a user's (smoker's) inhalation, which may refer to drawing in through the user's mouth or nose into the user's oral cavity, nasal cavity, or lungs.

[0035] In the following examples, "sheet" may refer to a thin layer element having a width and length substantially greater than its thickness. In the art, the term sheet may be used interchangeably with terms such as web and film.

[0036] In the examples below, "flavor sheet" or "flavoring sheet" may refer to a flavoring-containing material manufactured in sheet form.

[0037] Various embodiments of the present disclosure are described in detail below.

[0038] According to various embodiments of the present disclosure, a flavored sheet can be provided that can impart not only olfactory (or gustatory) effects but also auditory effects to a smoking article. In other words, a flavored sheet can be provided that can function as a sound-generating element in a smoking article. The provided flavored sheet is manufactured to have porosity, and can generate sound when burned (or heated). For example, sound can be generated when pores (or a membrane forming the pores) formed in the flavored sheet burst when burned (or heated). In addition, the provided flavored sheet can gradually release flavor fixed therein during smoking, thereby improving flavor expression and flavor persistence of the smoking article.

[0039] The scented sheet according to the embodiment may be manufactured by preparing a sheet composition in a liquid state (e.g., a slurry state) and drying the prepared sheet composition. Here, the liquid state may include not only a liquid state but also a state in which a liquid and a solid are mixed (e.g., a slurry state). For example, the scented sheet may be manufactured by applying (casting) the sheet composition onto a predetermined substrate and drying it. However, the method is not limited thereto, and the specific manufacturing method may be changed.

[0040] The detailed composition of the sheet composition can be designed in various ways.

[0041] In some embodiments, the sheet composition may include a solvent such as distilled water and / or ethanol, a hydrocolloid material, and an oil-based flavoring. The flavored sheet produced from such a sheet composition has porosity and can function as a sound-generating element in a smoking article. For example, a hydrophilic hydrocolloid material and a lipophilic flavoring are mixed together with a solvent to form a number of pores in the composition, and the sheet composition is dried to produce a porous flavored sheet. Hereinafter, each component of the sheet composition will be described.

[0042] A solvent such as distilled water or ethanol can be an element for adjusting the viscosity of the slurry sheet composition.

[0043] Next, the hydrocolloid material can be a material that coats and fixes the flavoring and can also be a sheet forming agent that forms a sheet. Examples of hydrocolloid materials include, but are not limited to, gelatin, agar, gellan gum, pectin, guar gum, xanthan gum, glucomannan, hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), ethylcellulose (EC), carboxymethylcellulose (CMC), starches, etc. Hydrocolloid materials become viscous spontaneously when in contact with a solvent (e.g., distilled water, ethanol), so they can be attached to the wrapper of a smoking article without a separate adhesive, which can simplify the process of placing the flavoring sheet and eliminate safety issues caused by adhesives.

[0044] In some embodiments, the sheet composition may include modified cellulose among various hydrocolloid materials. Here, "modified cellulose" may refer to cellulose in which a specific functional group is substituted in the molecular structure. Examples of modified cellulose include, but are not limited to, HPMC, MC, CMC, and EC. For example, HPMC may have a grade within a range of about 4 to 40,000 depending on the ratio of hydroxypropyl groups and methyl groups (or methoxy groups) substituted and the molecular weight. The viscosity of the modified cellulose may be determined depending on the grade. More specifically, the physicochemical properties of HPMC are related to the ratio of methoxy groups, the ratio of hydroxypropyl groups, and the molecular weight, and according to the United States Pharmacopeia (USP), the types of HPMC may be classified into HPMC1828, HPMC2208, HPMC2906, HPMC2910, etc. depending on the ratio of methoxy groups and hydroxypropyl groups. Here, the first two numbers may refer to the ratio of methoxy groups, and the last two numbers may refer to the ratio of hydroxypropyl groups. As a result of continuous experiments by the present inventors, it has been confirmed that perfumed sheets made from sheet compositions containing modified cellulose have excellent sheet physical properties and fragrance retention.

[0045] Next, examples of oil-based fragrances include natural oils extracted from plants, trees, and their fruits (e.g., cinnamon, sage, herbs, chamomile, dried grass, sweet tea, cloves, lavender, cardamom, clove fragrance, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang-ylang, fennel, anise, licorice, St. John's bread, plum extract, peach extract, etc.), but are not limited to these.

[0046] Meanwhile, in some embodiments, the sheet composition may further include LM-pectin (low methoxyl pectin). LM-pectin is a low ester pectin or low methoxyl pectin that is relatively little esterified, and specifically, it may mean a pectin containing less than about 50% carboxyl groups inside the molecular structure. Unlike carrageenan, LM-pectin has the property of not gelling when cooled, so that the viscosity of the slurry sheet composition can be reduced (for example, about 600 cp to 800 cp). In addition, since the slurry sheet composition can be produced without an emulsifier, it can be free from safety issues caused by emulsifiers.

[0047] LM-pectin can contain less than about 50%, less than about 40%, less than about 30%, less than about 20%, or less than about 10% of carboxy groups within its molecular structure. The lower the carboxy content within the molecular structure of the LM-pectin, the lower the viscosity of a slurry containing the LM-pectin can be.

[0048] In some embodiments, the sheet composition may further include a bulking agent. The bulking agent can increase the total mass (i.e., dry mass) of components other than distilled water to increase the volume of the produced fragrance sheet, and can be a substance that does not affect the original function of the fragrance sheet. Specifically, the bulking agent can have properties that increase the volume of the fragrance sheet but do not substantially increase the viscosity of the slurry and at the same time do not adversely affect the fragrance retention function of the fragrance sheet. In addition, the bulking agent can increase the size of the pores through the increase in the volume of the fragrance sheet, thereby enhancing the sound generation function of the fragrance sheet.

[0049] Preferably, the bulking agent may be, but is not limited to, starches, modified starches, or starch hydrolysates.

[0050] Here, modified starch refers to starch acetate, oxidized starch, hydroxypropyl distarch phosphate, hydroxypropyl starch, distarch phosphate, monostarch phosphate, phosphorylated distarch phosphate, and the like.

[0051] Moreover, the term "starch hydrolysate" refers to a substance obtained by a process including a step of hydrolyzing starch. The starch hydrolysate may include, for example, a substance obtained by directly hydrolyzing starch (i.e., dextrin), or a substance obtained by hydrolyzing starch after heat treatment (i.e., resistant dextrin). The bulking agent may be, for example, dextrin, more specifically, cyclodextrin.

[0052] The starch hydrolysate may generally be a starch hydrolysate having a DE value in the range of about 2 to about 40, preferably a starch hydrolysate having a DE value in the range of about 2 to about 20. Examples of starch hydrolysates having a DE value in the range of about 2 to about 20 that may be used include Pine Index #100 (Matsutani Chemical Industry Co., Ltd.), Pine Fiber (Matsutani Chemical Industry Co., Ltd.), and TK-16 (Matsutani Chemical Industry Co., Ltd.).

[0053] Here, "DE" is an abbreviation for dextrose equivalent, and the DE value indicates the degree of hydrolysis of starch, i.e., the saccharification rate of starch. In the present disclosure, the DE value may be a value measured by the Willstatter-Schudel method. The properties of hydrolyzed starch (starch hydrolysate), such as the molecular weight of the starch hydrolysate and the arrangement of sugar molecules constituting the starch hydrolysate, are not constant for each molecule of the starch hydrolysate, but exist with any distribution or variation. Depending on the distribution or variation of the properties of the starch hydrolysate, or the difference in the section to be cut, the starch hydrolysate can express different physical properties (e.g., DE value) for each molecule. In this way, the starch hydrolysate is a collection of molecules that exhibit different physical properties, but the measurement result using the Willstatter-Schudel method (i.e., DE value) is treated as a representative value indicating the degree of hydrolysis of starch.

[0054] Preferably, the starch hydrolysate may be selected from the group consisting of dextrin having a DE value of about 2 to about 5, resistant dextrin having a DE value of about 10 to about 15, and mixtures thereof. As a dextrin having a DE value of about 2 to about 5, for example, Pine Index #100 (Matsutani Chemical Industry Co., Ltd.) may be used. As a resistant dextrin having a DE value of about 10 to about 15, for example, Pine Fiber (Matsutani Chemical Industry Co., Ltd.) may be used.

[0055] In some embodiments, the sheet composition may further include a plasticizer, which can improve the physical properties of the sheet by providing the fragrance sheet with suitable flexibility. The plasticizer can include, but is not limited to, at least one of glycerin and propylene glycol.

[0056] In some embodiments, the sheet composition may further include an emulsifier. The emulsifier acts as a bridge between the highly lipophilic fragrance and the water-soluble hydrocolloid material, thereby increasing the fragrance retention and fragrance retention of the fragrance sheet. Examples of emulsifiers include, but are not limited to, lecithin.

[0057] The perfume sheet manufactured from the above-mentioned sheet composition may have various content ratios (composition ratios).

[0058] In some embodiments, the fragrance sheet may contain about 10 to 30 parts by weight of oil-based fragrance, preferably about 12 to 28 parts by weight, or about 14 to 26 parts by weight, of the total 100 parts by weight. Within such a range of values, an appropriate level of fragrance expression and sound effect can be ensured, and the sheet can be well formed. For example, if the content of the oil-based fragrance is too low, the fragrance expression may be reduced, and the sound may not be well generated due to poor pore formation. On the other hand, if the content of the oil-based fragrance is too high, a large number of pores may be generated, the content of the sheet forming agent may be reduced, and the sheet may not be well formed.

[0059] In some embodiments, the fragrance sheet may contain, based on a total of 100 parts by weight, about 2 to about 15 parts by weight of moisture, about 25 to about 90 parts by weight of modified cellulose, and about 10 to about 30 parts by weight of oil-based fragrance.

[0060] In some embodiments, the fragrance sheet may contain, based on a total of 100 parts by weight, about 2 to about 15 parts by weight of water, about 1 to about 60 parts by weight of a hydrocolloid substance, about 1 to about 60 parts by weight of LM-pectin, and about 10 to about 30 parts by weight of an oil-based fragrance.

[0061] In some embodiments, the plasticizer may be present in an amount of about 0.1 to 15 parts by weight based on 100 parts by weight of the total fragrance sheet. A sheet having appropriate flexibility may be formed within this range. For example, if too little plasticizer is added, the flexibility of the sheet may decrease and the fragrance sheet may be easily damaged during processing, and if too much plasticizer is added, the sheet may not be formed well.

[0062] According to various embodiments of the present disclosure, a smoking article that generates a sound during smoking may be provided. Specifically, the above-mentioned porous flavored sheet may be applied to the smoking article to generate a sound during smoking, thereby providing the smoker with an improved smoking experience. Hereinafter, the smoking article (e.g., 100) according to various embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0063] FIG. 1 is an exemplary diagram that diagrammatically illustrates a smoking article 100 according to some embodiments of the present disclosure.

[0064] As shown in Fig. 1, the smoking article 100 may include a filter portion 120, a smoking material portion 110, and a wrapper 130. However, Fig. 1 only illustrates components related to the embodiments of the present disclosure. Therefore, a person skilled in the art to which the present disclosure pertains will understand that other general components may be included in addition to the components illustrated in Fig. 1. Also, Fig. 1 only illustrates an example of some of the smoking articles according to various embodiments of the present disclosure, and the detailed structure of the smoking article may be different from that illustrated in Fig. 1. For other examples of the detailed structure of the smoking article, please refer to Figs. 6 and 7. Each component of the smoking article 100 will be described below.

[0065] The filter unit 120 can perform a filtering function for the smoke and / or aerosol generated by the smoking material unit 110. To this end, the filter unit 120 can include a filter (filter) material. Examples of the filter material include cellulose acetate fiber, paper, etc., but the scope of the present disclosure is not limited thereto. The filter unit 120 can further include a wrapper 130 that wraps the filter material (plug).

[0066] The filter portion 120 may be located downstream of the smoking material portion 110 and connected to the downstream end of the smoking material portion 110. For example, the filter portion 120 and the smoking material portion 110 may have a cylindrical (rod) shape, be aligned in the longitudinal direction, and be connected by a tipping wrapper. The tipping wrapper may wrap at least a portion of the filter portion 120 and at least a portion of the smoking material portion 110 together to connect the filter portion 120 and the smoking material portion 110. When the filter portion 120 forms the downstream end of the smoking article 100, the filter portion 120 may function as a mouthpiece that contacts the smoker's mouth.

[0067] The filter unit 120 is manufactured in the form of a rod, and may be referred to as a "filter rod 120" in some cases. The filter unit 120 may be manufactured in various forms, such as a cylindrical type, a tube type having a hollow inside, a recessed type, and the like.

[0068] The smoking material portion 110 may then include a smoking material that can be burned or heated to generate smoke and / or aerosol. The smoking material portion 110 may further include a wrapper 130 that encases the smoking material.

[0069] The smoking material portion 110 may be located upstream of the filter portion 120 and connected to the upstream end of the filter portion 120. Smoke and / or aerosol generated in the smoking material portion 110 may be delivered to the smoker's mouth through the filter portion 120 by puffs.

[0070] The portion of smoking material 110 is also manufactured in the form of a rod and may therefore sometimes be referred to as a "rod of smoking material 110."

[0071] The smoking material may include, for example, tobacco material. The tobacco material may include, for example, tobacco leaf shreds, tobacco stems, or materials processed therefrom. More specifically, the tobacco material may include, for example, crushed tobacco leaves, crushed reconstituted tobacco, expanded shreds, expanded midribs, and tabular leaves. However, the tobacco material may be in the form of, but is not limited to, tobacco shreds, tobacco particles, tobacco sheets, tobacco beads, tobacco granules, or tobacco extract.

[0072] In some embodiments, the smoking material may further include additives such as humectants, flavorings, and / or organic acids. For example, the humectants may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The humectants may maintain an appropriate level of moisture within the tobacco material to soften the inherent taste and to enrich the atomization volume. Flavoring agents may also include, for example, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander, clove extract (or clove substance) or coffee.

[0073] Next, the wrapper 130 may refer to one that encases at least a portion of the smoking material portion 110 and / or the filter portion 120. The wrapper 130 may refer to an individual wrapper for the smoking material portion 110 or the filter portion 120, or may refer to a wrapper that encases at least a portion of both the smoking material portion 110 and the filter portion 120, such as a tipping wrapper, or may refer to all wrappers used in the smoking article 100. The wrapper 130 may be made of a porous or non-porous wrapping paper, although the scope of the present disclosure is not limited thereto. For example, the wrapper 130 may be made of a metal foil or a laminate of wrapping paper and metal foil.

[0074] According to various embodiments of the present disclosure, as shown, a flavored sheet 10 functioning as a sound generating element may be applied to the smoking material portion 110 and / or the wrapper 130. In this way, sound may be generated during smoking, providing the smoker with an improved smoking experience, although the specific manner of application may vary depending on the embodiment.

[0075] 2, the shredded material 11 of the flavored sheet 10 may be mixed with shreds (111; e.g. shredded tobacco leaves, shredded slabs, etc.) and placed in the smoking material portion 110. In this case, the shredded material 11 is uniformly distributed in the smoking material portion 110, so that a constant sound volume can be continuously generated during smoking.

[0076] Also, in some embodiments, as shown in Fig. 3, the flavor sheet 10 may be placed in the smoking material section 110 together with the tobacco sheet 20. Here, the tobacco sheet 20 is a tobacco material manufactured in a sheet form, and may be, but is not limited to, reconstituted tobacco such as tabular tobacco. In this embodiment, the flavor sheet 10 may be appropriately mixed with the tobacco sheet 20 (e.g., the flavor sheet 10 may be laminated on the tobacco sheet 20 or wrapped around the tobacco sheet 20) and placed in the smoking material section 110.

[0077] Also, in some embodiments, as shown in FIG. 4 or FIG. 5, the flavored sheet 10 may be disposed (applied) inside the wrapper 130. For example, as shown in FIG. 4, the flavored sheet 10 may be disposed to extend in the length direction of the smoking article 100. In this case, a certain volume of sound may be continuously generated during smoking. As another example, as shown in FIG. 5, a plurality of flavored sheets 10-1 to 10-3 may be disposed at intervals inside the wrapper 130. In this case, the spacing between the flavored sheets may be the same or different. In this case, a sound may be generated at a predetermined time interval during smoking, providing the smoker with a unique smoking experience.

[0078] In the above embodiment, when at least a portion of the wrapper 130 is made of metal foil, the scented sheet 10 may be placed inside the metal foil. In this case, the scent release and sound generation of the scented sheet 10 may be further promoted by the heat transferred through the metal foil.

[0079] The manner in which the perfume sheet 10 is disposed on the wrapper 130 may vary.

[0080] In some examples, a wrapping material may be manufactured by overlapping (attaching) the fragrance sheet 10 to wrapping paper, and the manufactured wrapping material may be used as the wrapper 130. In this case, if the fragrance sheet 10 contains a hydrocolloid material, the fragrance sheet 10 may be attached to the wrapping paper without a separate adhesive. For example, the fragrance sheet 10 may be attached to the wrapping paper without an adhesive by spraying a liquid such as water or ethanol onto the fragrance sheet 10, because the hydrocolloid material independently becomes viscous when it comes into contact with the exemplified liquid. In this case, there is an advantage in that it may be free from safety issues caused by adhesives.

[0081] In some other examples, a wrapping material may be produced through a coating process in which the sheet composition from which the perfume sheet 10 is made is applied to wrapping paper and dried, and the produced wrapping material may be used as the wrapper 130.

[0082] Meanwhile, in some examples, the flavored sheet 10 may constitute at least a part of the wrapper 130. That is, the flavored sheet 10 itself can function as the wrapper 130 of the smoking article 100. In this case, at least a part of the wrapper 130 may be constituted only by the flavored sheet 10, or may be constituted in a form in which the flavored sheet 10 is integrated with wrapping paper. In such a case, it is not necessary to perform a step of placing the flavored sheet 10 on the wrapper 130 (e.g., a layering step, a coating step), and the manufacturing process of the smoking article 100 can be further simplified.

[0083] Meanwhile, in some embodiments of the present disclosure, the sound generation pattern during smoking can be adjusted by changing the size (e.g., length, thickness), porosity, placement position, placement interval and / or placement form of the flavored sheet 10.

[0084] For example, as shown in FIG. 5, by arranging flavored sheets 10-1 to 10-3 at regular intervals, it is possible to make sounds at regular intervals when smoking.

[0085] As another example, the size of the flavored sheet 10 disposed on the wrapper 130 may be increased or decreased in the downstream direction, so that the sound may gradually get louder or quieter as smoking progresses. In this case, the change in sound may have the effect of informing the smoker that he or she has finished smoking.

[0086] As another example, the porosity of the flavored sheet 10 disposed in the wrapper 130 can be increased or decreased toward the downstream side, so that the sound can be gradually increased or decreased as smoking progresses. In this case, the effect of informing the smoker of the end of smoking through the change in sound can be achieved. In this example, the porosity of the flavored sheet 10 can be adjusted based on, for example, the content of the oil-based flavoring, the content of the filler, drying conditions, etc., but is not limited thereto.

[0087] As yet another example, the intervals between the flavored sheets 10 may be made wider or narrower in the downstream direction, so that the intervals between sound emissions may become larger or smaller as smoking progresses.

[0088] So far, smoking articles 100 according to several embodiments of the present disclosure have been described with reference to Figures 1 to 5. As described above, by applying a porous flavored sheet 10, a smoking article 100 that generates sound during smoking can be easily manufactured, and an improved smoking experience can be provided to the smoker.

[0089] Hereinafter, smoking articles 200, 300 according to other embodiments of the present disclosure will be described with reference to Figures 6 and 7. However, for the sake of clarity of the present disclosure, a description of the contents overlapping with the smoking article 100 described above will be omitted.

[0090] FIG. 6 is an exemplary diagram showing a smoking article 200 according to some other embodiments of the present disclosure.

[0091] As shown in FIG. 6, the smoking article 200 may include a smoking material portion 210 and a filter portion 220, and the filter portion 220 may include a plurality of segments 221, 222.

[0092] The smoking material portion 210 may correspond to the smoking material portion 110 described above, and therefore, a description thereof will be omitted.

[0093] Next, the filter section 220 may be composed of a first segment 221 and a second segment 222. Of course, the filter section 220 may further include a third segment (not shown).

[0094] The first segment 221 may perform a cooling function for the smoke and / or aerosol generated in the smokable material portion 210. Therefore, the first segment 221 may be referred to as a "cooling segment 221" or a "cooling portion 221" depending on the circumstances.

[0095] The first segment 221 may be manufactured in various forms. As an example, the first segment 221 may be a paper tube formed of a paper material and having a cylindrical shape including a hollow. As another example, the first segment 221 may be manufactured of a polymeric material or a biodegradable polymeric material. For example, the first segment 221 may be manufactured of polylactic acid (PLA) fiber, but is not limited thereto. As yet another example, the first segment 221 may be manufactured of a cellulose acetate filter having a plurality of holes. As yet another example, the first segment 221 may be a tube filter including a hollow. For example, the first segment 221 may be a cellulose acetate filter including a hollow. However, the first segment 221 may be manufactured in a form different from that exemplified above, as long as it can perform a cooling function.

[0096] Second segment 222 may then perform a filtering function on the smoke and / or aerosols that have passed through first segment 221. Therefore, second segment 222 may be referred to as "filter segment 222" or "filter portion 222" in some cases. Alternatively, second segment 222 may be referred to as "mouthpiece segment 222" or "mouthpiece portion 222" since it is located in the mouthpiece portion.

[0097] In some embodiments, the second segment 222 may include at least one capsule 240. Here, the capsule 240 may perform a function of generating a flavor or a function of generating an aerosol. For example, the capsule 240 may have a structure in which a liquid containing a flavoring is enveloped in a membrane. Also, the capsule 240 may have a spherical or cylindrical shape, but is not limited thereto.

[0098] Next, the wrapper 230 may correspond to the above-described wrapper 130. Therefore, the description thereof will be omitted.

[0099] As mentioned above, the porous flavored sheet 10 functioning as a sound-generating element may be applied to the smoking material portion 210 and / or the wrapper 230. By doing so, the flavor release and flavor persistence of the smoking article 200 may be enhanced, and the sound generated during smoking may provide the smoker with an improved smoking experience.

[0100] Meanwhile, although not shown in Fig. 6, the smoking article 200 may further include a plug (not shown) disposed at an end. For example, the plug may be disposed at the upstream end of the smoking article 200 and function to appropriately adjust the overall length of the smoking article 200. In addition, when the smoking article 200 is inserted into an aerosol generating device (not shown), the plug may function to adjust the smoking material portion 210 to be disposed at an appropriate position inside the aerosol generating device.

[0101] FIG. 7 is an exemplary diagram that diagrammatically illustrates a smoking article 300 according to still other embodiments of the present disclosure.

[0102] As shown in FIG. 7, the smoking article 300 may include a smoking material section 310 and a filter section 320, each of which may include a plurality of segments 311, 312, 321, 322.

[0103] As shown, the smokable material portion 310 may be comprised of a first segment 311 and a second segment 312. Of course, the smokable material portion 310 may further include a third segment (not shown).

[0104] The first segment 311 may include a humectant. For example, the first segment 311 may include a crimped paper impregnated with a humectant. The humectant may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

[0105] The second segment 312 may then include a nicotine-generating substrate, such as a tobacco substance. The nicotine-generating substrate may include, for example, tobacco shreds, tobacco particles, tobacco sheets, tobacco beads, and tobacco granules. As another example, the nicotine-generating substrate may include a crinkled paper impregnated with a tobacco extract. When the nicotine-generating substrate is heated, nicotine may be generated from the nicotine-generating substrate and transferred to the filter portion 320.

[0106] Next, the filter unit 320 may also include a plurality of segments 321 and 322. For example, the filter unit 320 may include a third segment 321 performing a cooling function and a fourth segment 322 performing a filtering function. The above-described content regarding the filter unit 220 in FIG. 6 may be equally applied to the filter unit 320, and therefore further description will be omitted.

[0107] Next, the wrapper 330 may correspond to the above-described wrapper 130. Therefore, the description thereof will be omitted.

[0108] As mentioned above, the flavored sheet 10 functioning as a sound-generating element may be applied to the smoking material portion 310 and / or the wrapper 330. By doing so, the flavor development and flavor persistence of the smoking article 300 may be enhanced, and the sound generated during smoking may provide the smoker with an improved smoking experience.

[0109] So far, smoking articles 200, 300 according to several other embodiments of the present disclosure have been described with reference to Figs.

[0110] Hereinafter, the configuration and effects of the above-mentioned fragrance sheet 10 will be more clearly explained through examples and comparative examples. However, the following examples are merely illustrative of a portion of the present disclosure, and the scope of the present disclosure is not limited to the following examples.

[0111] Examples 1-2

[0112] A sheet composition having the composition disclosed in the preparation in Table 1 below was applied to a substrate and dried to produce a fragrance sheet having the composition disclosed in the finished product in Table 1 below.

[0113] [Table 1]

[0114] Comparative Examples 1 to 3

[0115] A sheet composition having the composition disclosed in the preparation in Table 2 below was applied onto a substrate and dried to produce a fragrance sheet having the composition disclosed in the finished product in Table 2 below.

[0116] [Table 2]

[0117] Experimental example: Evaluation of the ease of manufacturing fragrance sheets, quality, and sound emission level depending on the content of oil-based fragrance

[0118] For the fragranced sheets of Examples 1-2 and Comparative Examples 1-3, experiments were conducted to evaluate the workability (ease) of applying the sheet composition (liquid preparation) to a substrate and manufacturing the fragranced sheet using the substrate, the quality of the manufactured fragranced sheets, and whether or not they emitted sound.

[0119] Here, the quality of the fragrance sheet was evaluated based on the degree of pores formed in the fragrance sheet and the degree of flexibility, and whether it was suitable for use. The experimental results are shown in Table 3 below.

[0120] If the fragrance sheet had excellent workability, was of suitable quality for use, and produced no sound, it was marked with a circle. Conversely, if the workability was poor, the quality was not suitable for use, and no sound was produced, it was marked with an x.

[0121] [Table 3]

[0122] Referring to Table 3, it was confirmed that in the case of Example 1 and Example 2, which contained 14.9 wt % and 25.3 wt % of oil-based fragrance, respectively, the sheet production workability, sheet quality, and sound expression level were all excellent.

[0123] In contrast, in the cases of Comparative Example 1 and Comparative Example 3, which contained 2.8% by weight or no oil-based fragrance, no sound was produced, and in the case of Comparative Example 2, which contained 34.5% by weight of oil-based fragrance, the manufacturing workability was poor, the sheet quality was not suitable for use, and no sound was produced. These results are considered to show that the addition of an appropriate amount of oil-based fragrance can improve the manufacturing workability and physical properties of the fragranced sheet, as well as the sound production properties.

[0124] The configuration and effects of the above-mentioned fragrance sheet 10 have been explained more clearly through the examples and comparative examples.

[0125] Although the embodiments of the present disclosure have been described above with reference to the attached drawings, those skilled in the art will understand that the present disclosure can be embodied in other specific forms without changing the technical idea or essential features. Therefore, the above described embodiments should be understood to be illustrative in all respects and not limiting.
