In addition, in describing the present disclosure, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present disclosure, the detailed description thereof will be omitted.

Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used with the meaning commonly understood by those of ordinary skill in the art to which this disclosure belongs. In addition, terms defined in a commonly used dictionary are not to be interpreted ideally or excessively unless clearly defined in particular. The terminology used herein is for the purpose of describing the embodiments and is not intended to limit the present disclosure. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase.

In addition, in describing the components of the present disclosure, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only for distinguishing the elements from other elements, and the essence, order, or order of the elements are not limited by the terms. When it is described that a component is “connected”, “coupled” or “connected” to another component, the component may be directly connected or connected to the other component, but another component is formed between each component. It should be understood that elements may also be “connected,” “coupled,” or “connected.”

As used herein, “comprises” and/or “comprising” refers to a referenced component, step, operation and/or element of one or more other components, steps, operations and/or elements. The presence or addition is not excluded.

First, some terms used in this specification will be made clear.

As used herein, "smoking article" means any product capable of smoking or a smoking experience, whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. It may mean any product that can provide For example, smoking articles may include smokeable products such as cigarettes, cigars, and cigarillos.

As used herein, the term “smoking material” may include various types of substances that generate smoke and/or aerosol or are used for smoking. For example, the smoking material may comprise tobacco material. Tobacco material may include, for example, tobacco leaf pieces, tobacco stems or materials processed therefrom, and the like. As a more specific example, the tobacco material may include ground tobacco leaves, ground reconstituted tobacco, expanded stems, leaf cut filler, reconstituted tobacco sheets (e.g. leaflets), and the like.

As used herein, "upstream" or "upstream direction" means a direction away from the smoker's bend, and "downstream" or "downstream direction" may mean a direction approaching from the smoker's bend. . For example, in the smoking article 1 illustrated in FIG. 1 , the mouthpiece portion 11 is located downstream of the smoking article 1 . The terms upstream and downstream may be used to describe the relative positions of the constituent elements of a smoking article.

As used herein, "longitudinal direction" may mean a direction corresponding to the longitudinal axis of the smoking article.

Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

1 exemplarily shows a smoking article 1 with a wrapper reinforced around a mouthpiece in accordance with some embodiments of the present disclosure. 1 and the following drawings, the dotted arrow indicates the direction of movement of smoke or aerosol.

As shown in FIG. 1 , a smoking article 1 may include a smoking material portion 12 , a mouthpiece portion 11 , and a paper wrapper 13 . However, only the components related to the embodiment of the present disclosure are illustrated in FIG. 1 . Accordingly, one of ordinary skill in the art to which the present disclosure pertains can know that other general-purpose components other than those shown in FIG. 1 may be further included. For example, the smoking article 1 may further include a filter unit (not shown). Hereinafter, each component of the smoking article 1 is demonstrated.

The smoking material part 12 may include smoking material and may be implemented as an elongated smoking material rod. As the smoker puts the mouthpiece 11 in their mouth and inhales, the smoking material is burned to generate smoke and/or aerosol, and the generated smoke and/or aerosol may be inhaled through the smoker's mouth.

The smoking material may include tobacco material. Tobacco material may include, for example, leaf tobacco cut filler, reconstituted tobacco such as leaf cut filler, cut pieces of reconstituted tobacco such as sheet leaf cut filler, and the like. However, the present invention is not limited thereto.

In some embodiments, the smoking material may further include additives such as wetting agents, flavoring agents and/or organic acids. For example, the wetting agent may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Wetting agents can keep moisture in the tobacco material at an appropriate level, softening its intrinsic taste, and enriching the amount of atomization. In addition, flavoring agents 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, sage, spearmint, ginger, coriander, clove extract (or clove substance) or coffee can do.

In some embodiments, the smoking material may further include a clove material that acts as a sound generating factor. The clove material may include, for example, clove powder, clove plant fragments (pieces), etc. produced by grinding or processing clove plants (e.g. clove leaves). In such a case, since a crackling sound (or kritek-critek) is generated during smoking, a clove scent and an auditory effect are added, thereby providing a more improved smoking experience to the smoker.

Also, in some embodiments, the smoking material may further include a polysaccharide material that acts as a sound generating factor. The surprising fact that a polysaccharide material generates sound when burned was discovered during the course of continuous research by the present inventors. Through experiments, the present inventors confirmed that a certain sound was generated as the crystal structure was broken when the polysaccharide material was burned. The polysaccharide material may be added in place of the clove material or may be added together with the clove material. The polysaccharide material may be processed into, for example, particles, sheets, and elongated objects (e.g. toothpick shapes) to constitute a smoking material, but the technical scope of the present disclosure is not limited thereto. As a more specific example, the polysaccharide material in particulate form may be added to a wrapper that constitutes or wraps the smoking material. As another example, the polysaccharide material in the form of a sheet may constitute a smoking material together with a tobacco sheet (e.g. leaflets) or may be placed in a wrapper. As another example, the polysaccharide material in the form of an elongated object may be included in the smoking material in a shrunken state or an uncut state. According to the present embodiment, the sound generating effect of the smoking article is increased, so that a more improved smoking experience can be provided to the smoker. Furthermore, since the polysaccharide material (e.g. starch) is generally very inexpensive, the material cost of the smoking article 1 can be further reduced. Furthermore, since the polysaccharide material (e.g. starch) is a safe material that humans ingest as food, the safety of the smoking article 1 is ensured and the cost of the safety test can be greatly reduced.

In some embodiments, the smoking material may further comprise a health promoting material. The health promoting material may include, for example, at least one of ginseng, jamu, and betel. However, the present invention is not limited thereto, and other types of health-promoting substances may be included.

As a specific example, betel (e.g. the leaves of a Bettel plant) may be added during the manufacturing process of leaf tobacco cut filler, or a smoking material may be manufactured by mixing the prepared tobacco cut filler and Betel. Vettel is not only a health-promoting substance used as a gastric and expectorant, but also has a teeth-whitening effect. Therefore, when betel is included in the smoking material, tooth discoloration due to smoking can be prevented, and a beneficial effect can be given to the smoker.

As another example, a smoking material may be prepared by adding Jammu during the manufacturing process of leaf tobacco cut filler or by mixing the manufactured leaf tobacco cut filler and Jammu. Jammu refers to a medicinal plant in Indonesia, and contains various health-promoting ingredients. Therefore, when the grapefruit is included in the smoking material, the health-promoting component contained in the grapefruit plant may be expressed during smoking to give a beneficial effect to the smoker.

As another example, a ginseng extract may be added to leaf tobacco cut filler, or a ginseng material processed into a sheet form may constitute a smoking material together with leaf tobacco cut filler. Here, the ginseng or ginseng material may include both ginseng leaves, ginseng fruit, or their processed products and by-products. Ginseng has various health-promoting effects, such as improving immunity. Therefore, when ginseng is included in the smoking material, the health-promoting component of ginseng is expressed during smoking, thereby giving a beneficial effect to the smoker.

On the other hand, since the content of the health-promoting substance included in the smoking material is related to the health-promoting effect and the taste of tobacco, it may be important to appropriately determine the content. This is because, as the content of the health-promoting substance increases, the health-promoting effect will be strengthened, but the content of the tobacco substance may decrease and the taste of tobacco may deteriorate. The content of health-promoting substances may preferably be about 1% to 30% compared to tobacco substances. More preferably, the content may be about 5% to 25%, 10% to 30%, 10% to 25% or 5% to 20% relative to the tobacco material. Alternatively, the content may be about 10% to 20%, 15% to 25%, or 20% to 30% compared to tobacco material. Within this numerical range, it was confirmed that not only the tobacco taste but also the health-promoting effect was ensured.

Health-promoting substances, such as betel, jamu, and ginseng, may be processed into various forms and included in the smoking material. For example, the health-promoting material may be included in the smoking material in the form of cut pieces such as cut filler, powder, powder, or the like, granules, sheets, liquid extracts, or the like. When the health-promoting material is mixed with leaf tobacco cut filler in the form of cut cut materials, the difference between the cut cut width of the cut cut material and the cut cut width of the leaf tobacco cut filler may be 20% or less of the leaf tobacco cut cut width. Preferably, the difference may be no more than 15%, 13% or 10%. More preferably, the difference may be no more than 9%, 7% or 5%. In this numerical range, the breathability of the inside of the smoking article 1 is secured, so that the problem of lowering of combustibility and atomization during smoking can be solved.

Next, the mouthpiece portion 11 may refer to a portion where the smoker's mouth is located when smoking. 1 shows the mouthpiece part 11 and the smoking material part 12 as being separated from each other, this is only for convenience of understanding, and the mouthpiece part 11 is the smoking material part 12 or It may refer to a part of the filter unit (not shown). For example, when the smoking article 1 is not provided with a filter (section), the mouthpiece portion 11 may refer to a portion of the smoking material portion 12 . As another example, when the smoking article 1 includes a filter (part), the mouthpiece part 11 may refer to a part of the filter part.

Next, the paper wrapper 13 may refer to a paper structure surrounding the smoking material part 12 and/or the mouthpiece part 11 .

As illustrated in FIG. 1 , multiple wrapping may be performed around the mouthpiece 11 . For example, the paper wrapper 13 may include a first paper wrapper 132 surrounding the smoking material portion 12 and/or the mouthpiece 11 and a second paper wrapper 132 surrounding the first paper wrapper 131 . ) can be composed of Although FIG. 1 shows as an example that double wrapping is performed around the mouthpiece unit 11, the number of wrappings may be changed based on various factors such as the basis weight and thickness of the paper wrappers 131 and 132. The paper wrapper 13 having a multi-wrap structure can provide a more improved smoking experience by effectively preventing the wrapper around the mouthpiece 11 from getting wet or damaged due to the smoker's sweat, saliva, external moisture, etc. during smoking. .

The first paper wrapper 13 may mean a basic wrapper surrounding the smoking article 1 . The first paper wrapper 13 may correspond to a filter wrapper (ie, a plug wrap), a tipping wrapper, or the like, and a specific correspondence relationship may vary depending on the structure of the smoking article 1 . The first paper wrapper 13 may correspond to a paper structure including a smoking material wrapper surrounding the smoking material unit 12 , a filter wrapper surrounding the filter unit (not shown), and a tipping wrapper.

The second paper wrapper 132 may refer to a wrapper that is additionally provided to improve the moisture resistance of the wrapper around the mouthpiece unit 11 . The number, basis weight, thickness, length (ie, wrapping range) of the second paper wrapper 132 may be variously modified according to an embodiment. For example, the second paper wrapper 132 may wrap only the periphery of the mouthpiece 11 or wrap more.

In some embodiments, the basis weight of the first paper wrapper 131 or the second paper wrapper 132 may be 20 g/m ² to 40 g/m ² . More preferably, the basis weight may be 25 g/m ² to 35 g/m ² , 27 g/m ² to 32 g/m ² . Alternatively, the basis weight may be about 28 g/m ² . By repeatedly wrapping around the mouthpiece portion 11 with a paper wrapper having such a basis weight, the moisture resistance of the wrapper around the mouthpiece portion 11 can be effectively improved while preventing the downstream end of the smoking article 1 from becoming too thick. have.

In some embodiments, the basis weight of the second paper wrapper 132 may be greater than the basis weight of the first paper wrapper 131 . For example, the basis weight of the second paper wrapper 132 may be 40 g/m ² to 60 g/m ² , and the basis weight of the first paper wrapper 131 may be 20 g/m ² to 40 g/m ² .

Meanwhile, in some embodiments, a waterproof film may be disposed between the first paper wrapper 131 and the second paper wrapper 132 . The waterproof film may be, for example, a cellulose film having excellent waterproofness and biodegradability. However, the present invention is not limited thereto. As a more specific example, the waterproof film may be prepared by combining cellulose acetate fibers and triacetin at a set ratio. The combination ratio may be 85% cellulose acetate fiber and 14.5% triacetin, but is not limited thereto. According to the present embodiment, since the waterproof film disposed between the two paper wrappers 131 and 132 effectively blocks moisture penetration, the moisture resistance of the wrapper around the mouthpiece 11 may be further improved.

In addition, in some embodiments, an application layer that imparts waterproofness to the outer surface of the second paper wrapper 132 may be formed. For example, the application layer may include a first application layer formed by applying a coating composition. Alternatively, the application layer may further include at least one of a second application layer formed by applying a colored material (e.g. white ink) and a third application layer formed by applying a sweetener. The exemplified application layer will be described in detail later. According to the present embodiment, since the application layer formed on the outer surface of the second paper wrapper 132 effectively blocks moisture penetration, the moisture resistance of the wrapper around the mouthpiece unit 11 may be further improved.

Heretofore, descriptions have been made on the assumption that the smoking article 1 has a cylindrical shape in which the diameter or area of the upstream cross-section and the downstream cross-section is substantially the same or similar. However, in some other embodiments, the smoking article 1 may have other shapes.

For example, as illustrated in FIG. 2 , smoking article 1 may have a cone-like shape in which the diameter or area of the downstream cross-section is less than the diameter or area of the upstream cross-section. For example, the diameter or area of the downstream cross-section may be less than or equal to 90% of the diameter or area of the upstream cross-section. Some cigarette products without a filter (part) may have such a shape, but the smoking article 1 has a large contact area with the mouth, so that the wrapper around the mouthpiece part 11 may be relatively easily damaged. In addition, due to structural characteristics, when the wrapper is damaged, the smoking material can easily come out, which can be a problem. In particular, when the smoking material is in the form of cut pieces such as leaf tobacco cut filler or a pulverized material, it may more easily come out and the severity of the problem may be increased.

However, as illustrated in FIG. 2 , when the paper wrapper 13 for multiple wrapping around the mouthpiece 11 is applied, moisture resistance is greatly improved, so that the wrapper around the mouthpiece 11 is damaged or smoking during smoking. The problem of material sticking out can be solved.

Meanwhile, in some embodiments, the smoking article 1 may further include a filter unit (not shown). In this case, the upstream end of the filter part is connected to the downstream end of the smoking material part 12 , and the mouthpiece part 11 may constitute a part of the filter part. Hereinafter, the present embodiment will be described in more detail.

The filter unit (not shown) may include a filter material capable of filtering smoke and/or aerosols. The filter material may be, for example, cellulose acetate fibers. However, the present invention is not limited thereto. In some embodiments, the filter material may further comprise at least one filter material well known in the art. For example, the filter material may further comprise an adsorbent comprising carbon, activated carbon, and the like.

In some embodiments, the filter material is cellulose acetate fiber, and a plasticizer based on clove extract may be added during the manufacturing process of the filter. The present inventors conducted continuous research to develop an eco-friendly/natural plasticizer, and as a result of the study, surprisingly, it was confirmed that the clove extract had the property of plasticizing cellulose acetate tow. In addition, the present inventors also confirmed that the filter to which the clove extract is added has excellent biodegradability compared to the filter to which an artificial plasticizer (e.g. triacetin) is added. It can be understood that the improved biodegradability of the filter is due to the fact that the clove extract is a natural material extracted from the clove plant. The clove extract contains at least one component of beta-caryophyllene, eugenol, methyl-benzoate, caryophyllene oxide and eugenyl acetate. It may include, but is not limited to. According to this embodiment, by using the clove extract as a plasticizer, a filter having excellent biodegradability can be manufactured. Furthermore, when eugenol and eugenyl acetate-based clove extract are used as plasticizers, the amount of eugenol transfer during smoking is increased, so that the clove flavor delivered to the smoker can be further enhanced.

In the above-described embodiment, in order to further improve the performance of the plasticizer, the composition of the clove extract and the artificial plasticizer may be used as a plasticizer of the filter material. The artificial plasticizer may be, for example, but not limited to, triacetin. The composition ratio of the clove extract and the artificial plasticizer may be, for example, 1:1 to 5:1 or 2:1 to 3:1. Within this numerical range, the plasticizing performance and the biodegradability of the filter can be secured at the same time. However, the scope of the present disclosure is not limited to these examples, and the composition ratio may be appropriately determined in consideration of plasticization performance and biodegradability.

In addition, in some embodiments, clove extract (e.g. clove oil) may be added to the filter unit in the form of granules in order to add a flavor of clove flavor. For example, flavor granules comprising clove extract may be added to the entire filter unit, a specific segment of the filter unit (e.g. upstream segment), a cavity, and the like. The flavor granules may be prepared to have a porous structure. Since the porous structure can suppress the volatilization of the clove extract having volatility due to its structural characteristics, it is possible to improve the flavor retention of the flavor granules. In addition, as flavor granules are added to the filter unit, the clove flavor may be further enhanced. In some other embodiments, flavor granules comprising clove extract may be added to the smoking material portion or various wrappers.

Also, in some embodiments, clove extract (eg clove oil) may be added to the filter material in liquid form to add a clove flavor. In this case, the filter material may be a cellulosic material (eg paper) having a bulk greater than or equal to a reference value. For example, the bulk of the cellulosic material may be greater than or equal to 1.0 cm ³ /g, 2.0 cm ³ /g, 2.5 cm ³ /g, or 3.0 cm ³ /g. Here, the bulk means a value obtained by dividing the thickness by the basis weight, and since the high bulk cellulose material contains many pores therein, a large amount of hyangaek can be accommodated. In addition, due to this, it is possible to add a large amount of perfume to the filter, so that the flavor expression can be doubled. In addition, since the high bulk cellulosic material can suppress the rapid volatilization of volatile fragrance liquids such as clove extract through a complex pore structure, the fragrance persistence of the filter can also be improved.

So far, a smoking article 1 in which a wrapper around a mouthpiece is reinforced according to some embodiments of the present disclosure has been described with reference to FIGS. 1 and 2 . Hereinafter, a smoking article 2 with a reinforced wrapper around the mouthpiece according to some other embodiments of the present disclosure will be described.

3 exemplarily shows a smoking article 2 . Hereinafter, for clarity of the specification, descriptions of contents overlapping with the previous embodiment will be omitted, and the description will be continued focusing on differences from the previous embodiment.

As shown in FIG. 3 , the smoking article 2 includes a smoking material portion 22 , a mouthpiece portion 21 , a paper wrapper 23 , and an application layer 24 formed on the outer surface of the paper wrapper 23 . can do. The smoking material unit 22 , the mouthpiece unit 21 , and the paper wrapper 23 may correspond to the smoking material unit 12 , the mouthpiece unit 11 , and the first paper wrapper 131 of the previous embodiment, respectively. . If the paper wrapper 23 adopts a multi-lapping structure, the paper wrapper 23 may correspond to a paper structure including the first paper wrapper 131 and the second paper wrapper 132 .

The application layer 24 may be formed on the outer surface of the paper wrapper 23 to improve the moisture resistance of the wrapper around the mouthpiece unit 21 . The application layer 24 may be formed as a coating composition imparting waterproofness is applied. The application layer 24 improves the moisture resistance of the paper wrapper 23 , thereby preventing the wrapper around the mouthpiece 21 from getting wet or damaged during smoking. The thickness, length (ie, application range) of the coating layer 24 , the amount of coating composition applied, the type of material constituting the coating composition, etc. may vary depending on the embodiment. The application layer 24 may be formed only around the mouthpiece portion 21 or may be formed in a wider area.

The coating composition may include a coating material that imparts water resistance. For example, the coating material may be an acrylic resin (e.g. BR-113). However, the scope of the present disclosure is not limited to these examples.

In some embodiments, the application layer 24 may include a first application layer formed by the coating composition and a second application layer formed by a colored material (eg, white ink). For example, the above-described first coating layer and the second coating layer may be formed by applying the coating composition to the outer surface of the paper wrapper 23 and drying it and then applying a colored material. The colored material may prevent the paper wrapper 23 from discoloring due to moisture. For example, when the paper wrapper 23 gets wet and then dries (or over time), a yellow discoloration phenomenon may appear due to the characteristics of the paper material, and a colored material may prevent this phenomenon. Alternatively, the colored material prevents the paper wrapper 23 from becoming transparent by a coating composition such as an acrylic resin, thereby preventing the appearance of the smoking article 2 from being damaged. The second application layer may be formed on the first application layer, or vice versa.

In some embodiments, the application layer 24 may include a first application layer formed by the coating composition and a second application layer formed by a sweetener. For example, the above-described first and second coating layers may be formed by applying the coating composition to the outer surface of the paper wrapper 23 and drying it, and then applying a sweetener. The sweetener may be, for example, but not limited to, a saccharin material. The sweetener can provide the smoker with a more enhanced smoking experience by delivering a sweet taste to the smoker and reducing the taste buds. In order to more directly transfer the taste, it may be preferable that the second application layer is formed on the first application layer. However, the scope of the present disclosure is not limited thereto.

In some embodiments, the application layer 24 may include a first application layer formed by the coating composition, a second application layer formed by a colored material, and a third application layer formed by a sweetener. For example, the above-described first to third coating layers may be formed by sequentially applying and drying the coating composition, the colored material, and the sweetener on the outer surface of the paper wrapper 23 . In this case, not only can the aesthetics of the smoking article 2 be prevented from being damaged, but also a sweet taste can be transmitted to the smoker, so that the smoker's smoking satisfaction can be further improved. As in the previous embodiment, it may be preferable that the third application layer is formed on the outermost side. However, the scope of the present disclosure is not limited thereto.

In the above embodiments, the thickness of the application layer 24 may be about 3 μm to 30 μm. Preferably, the thickness may be about 5 μm to 25 μm, 5 μm to 20 μm, or 5 μm to 15 μm. Within this numerical range, it was confirmed that appropriate moisture resistance was imparted, and at the same time, the sense of heterogeneity felt by the smoker (ie, the feeling of contact when biting in the mouth) was minimized.

In addition, the application amount of the sweetener may be about 0.2g to 2.0g. Preferably, it may be about 0.3g to 1.5g, 0.4g to 1.5g, or 0.3g to 1.4g, more preferably, about 0.3g to 1.0g, 0.4g to 0.9g, or 0.3g to 0.8g can Within this numerical range, it was confirmed that the sweet taste was appropriately delivered. For example, if the application amount of the sweetener is too small, the taste of the sweetener may be hardly felt and taste and taste may be increased.

In addition, in order to maintain the thickness of the application layer 24 within an appropriate range, the application amount of the sweetener may be varied. For example, when the coating composition and the sweetener are applied to the application layer 24 , it is assumed that the application amount of the sweetener is equal to about 0.4 g to 1.5 g or about 0.4 g to 1.0 g. If so, when a colored material is further applied to the application layer 24 , it may be preferable that the application amount of the sweetener is reduced by about 0.05 g to 0.2 g.

Meanwhile, although not shown, the smoking article 2 may be a conical article as illustrated in FIG. 2 .

So far, the smoking article 2 according to some other embodiments of the present disclosure has been described with reference to FIG. 3 .

Hereinafter, the configuration and effects of the smoking articles 1 and 2 described above will be made clearer through comparative examples and examples. However, since the following embodiments are only some examples of the smoking articles 1 and 2, the scope of the present disclosure is not limited by the following embodiments.

Comparative Example 1

A smoking article (eg a water cigarette such as SKT cigarettes) having a cone-like shape and not including a filter was prepared as illustrated in FIG. 2 . As a wrapper for the mouthpiece part, a paper wrapper having a basis weight of about 27 g/m ² and a thickness of about 27 μm was used.

A smoking article similar to Comparative Example 1 was prepared, except that the mouthpiece portion was double-wrapped.

Example 2

A smoking article similar to that of Comparative Example 1 was prepared, except that an acrylic resin and a sweetener were applied to the mouthpiece. The thickness of the coating layer was about 10 μm, and the application amount of the sweetener was about 0.570 g.

Example 3

A smoking article similar to Comparative Example 1 was prepared, except that an acrylic resin, a white ink material, and a sweetener were applied to the mouthpiece. The thickness of the coating layer was about 10 μm, and the application amount of the sweetener was about 0.454 g.

Example 4

A smoking article similar to Example 3 was prepared, except that the thickness of the coating layer was about 20 μm and the amount of the sweetener was about 1.54 g.

Example 5

A smoking article similar to that of Example 3 was prepared, except that the thickness of the coating layer was about 8 μm and the amount of the sweetener was about 0.24 g.

Experimental Example 1: Evaluation of the durability (moisture resistance) of the wrapper

For the smoking articles for Comparative Example 1 and Examples 1 to 3, an experiment was conducted to evaluate the durability (moisture resistance) of the mouthpiece portion wrapper. Specifically, a panel of 10 people was asked to smoke using each smoking article, and it was observed whether or not the wrapper of the mouthpiece part was damaged after smoking was finished. In addition, the same experiment was repeated a total of 30 times. The experimental results are shown in Table 1 below.

division Damage probability (%) note Comparative Example 1 16.6 Damage occurred 5 times in total
2 occurrences of cut filler coming into the mouth through damaged wrappers Example 1 0.03% 1 occurrence of damage Example 2 0% almost never wet Example 3 0% almost never wet

Referring to Table 1, it can be seen that the wrapper durability of the smoking articles according to the Examples is significantly superior to that of the Comparative Examples. In particular, in the case of Comparative Example 1, as the mouthpiece wrapper was damaged, it was also observed that the mouthpiece enters the mouth during smoking. Able to know.

In addition, in the case of Examples 2 and 3, it was found that the wrapper hardly got wet due to the application layer formed by the acrylic resin, which shows that the acrylic resin can impart strong moisture resistance to the wrapper.

Experimental Example 2: Sensory evaluation of smoking articles

With respect to the smoking articles according to Comparative Example 1 and Examples 1 to 5, an experiment was performed for sensory evaluation of overall smoking satisfaction. Specifically, sensory evaluation was performed for suckability, off-taste, tobacco taste, appearance aesthetics, and heterogeneity (feeling of being bitten at work). The sensory evaluation was conducted for a total of 25 panelists, and the perfect score was set at 5 points. The sensory evaluation results are shown in Table 2 below.

division Comparative Example 1 Example 1 Example 2 Example 3 Example 4 Example 5 suckability 4.02 4.01 4.03 3.99 4.02 4.01 hobbies 3.9 3.89 3.72 3.73 3.65 3.83 tobacco flavor 3.9 3.92 3.99 3.91 3.82 3.93 exterior aesthetics 3.95 3.99 3.91 4.1 4.12 4.11 heterogeneity 4.1 4.08 4.07 4.07 3.95 4.07

Referring to Table 2, in the case of suckability, there was no significant difference between the comparative examples and the examples, which is thought to be because multi-lapping and treatment such as coating composition application are performed on the outer surface of the paper wrapper.

It was found that taste taste decreased as the amount of sweetener applied increased. However, in the case of Example 4 to which the sweetener was applied the most, it was found that the tobacco taste was inferior to that of Comparative Example 1.

In the case of aesthetic appearance, the difference was not large, but the smoking article according to Example 2 received the lowest evaluation, which is considered to be the main factor due to the transparent change of the paper wrapper due to the acrylic resin. That is, it is judged that the wrapper appearance different from the general tobacco product gave a bad feeling to the smoker. In addition, the reason that the smoking articles according to Comparative Examples 1 and 1 received lower ratings compared to Examples 3 to 5 is judged to be because discoloration occurred during the drying of the wet wrapper after smoking.

Finally, in the case of heterogeneity, the difference is not large, but the smoking article according to Example 4 received the lowest evaluation, which is judged because the feeling coated by the coating composition and the thick thickness of the application layer gave a somewhat heterogeneous feeling. . However, looking at the cases of Examples 2, 3 and 5, it is determined that the heterogeneity due to the coating composition is not so great.

Up to now, the configuration and effects of the above-described smoking articles 1 and 2 have been described in detail through comparative examples and examples.
