Description

[Technical field]

[0001] The present disclosure relates to sound-producing smoking articles, and more particularly to smoking articles that can provide smokers with an enhanced smoking experience by providing additional auditory effects when smoking. [Background technology]

[0002] There has been active research into technologies that can provide a differentiated smoking experience through smoking articles. However, most of the existing research has focused on taste, smell and / or visual differentiation among the various senses that consumers can sense, and research into auditory differentiation has been very limited in comparison. For example, existing research topics have focused on technologies for adding aroma to smoking articles (taste / smell differentiation) and technologies for increasing the amount of aerosol from smoking articles (visual differentiation).

[0003] Meanwhile, an example of a smoking article related to auditory differentiation is the Indonesian kretek cigarette. When smoked, the clove substance burns, producing a crackling sound called a crackling sound (or kritik-kritik), and the name "kretek" is derived from this characteristic.

[0004] However, kretek cigarettes are cigarettes to which clove substances have been added in order to produce a clove aroma (i.e., for taste / olfactory differentiation), so strictly speaking, they are difficult to see as the product of research into auditory differentiation. In addition, the clove substances added to kretek cigarettes have an irregular arrangement, which results in irregular patterns of sounds (e.g., sound intensity, intervals between sounds) being generated during smoking, which can sometimes be perceived as noise by smokers and provide a worse smoking experience. Moreover, users who are not accustomed to the scent of clove may feel a considerable aversion to kretek cigarettes. Summary of the Invention [Problem to be solved by the invention]

[0005] The technical problem to be solved through some embodiments of the present disclosure is to provide a smoking article that can provide a smoker with an improved smoking experience by providing additional auditory effects when smoking.

[0006] Another technical problem to be solved through some embodiments of the present disclosure is to provide a smoking article that can continuously generate a constant sound during smoking.

[0007] Yet another technical problem that some embodiments of the present disclosure aim to solve is to provide a sound-emitting smoking article that is inexpensive and easy to manufacture.

[0008] Yet another technical problem to be solved through some embodiments of the present disclosure is to provide a substance that generates sound when burned and a method for producing the same.

[0009] Yet another technical problem to be solved through some embodiments of the present disclosure is to provide a sound-generating material and a manufacturing method thereof that can be universally applied to various smoking articles.

[0010] The technical problems of the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person of ordinary skill in the art of the present disclosure from the following description. [Means for solving the problem]

[0017] In some embodiments, the smoking material portion includes tobacco material, and the content of the sound-producing material relative to the tobacco material may be between 2% and 30% by weight.

[0018] In some embodiments, glycerin may be added during the manufacturing process of the sound-producing material, but no hardener may be added.

[0019] In some embodiments, the manufacturing process of the sound-generating material may include a molding step of feeding a mixed solution containing the carbohydrate material into a molding device and molding it into a predetermined shape, and a drying step of drying the result of the molding step.

[0020] In some embodiments, the drying step may be carried out at a temperature of 20° C. to 40° C. and a relative humidity of 10% to 40% for 5 hours or more.

[0021] In some embodiments, the manufacturing process of the smoking material part includes a rod forming step in which smoking material is poured onto a wrapping material to form a rod, and the sound-generating material may be poured in a machine direction (MD) during the rod forming step.

[0025] Furthermore, by incorporating the sound-producing material together with the tobacco material during the manufacture of the smoking article, the effect on the workability of the smoking article can be minimized.

[0026] In addition, when manufacturing a smoking article, the sound-generating material is fed in the MD (machine direction) through a separate feeder, so that the sound-generating material can be arranged regularly inside the smoking material part, which allows a regular pattern of sound (e.g., sound intensity, sound generation interval) to be generated during smoking, providing the smoker with a more improved smoking experience.

[0027] Also, by producing a sound producing material based on low cost carbohydrate materials, inexpensive sound producing smoking articles can be produced.

[0028] Also, by producing sound-producing substances based on carbohydrate substances that people consume in food, the safety of smoking articles can be ensured.

[0029] In addition, by utilizing a sound-generating substance unrelated to the scent of cloves, a smoking article that generates sound can be provided for smokers who are not accustomed to the scent of cloves. That is, by producing a sound-generating substance based on a carbohydrate substance unrelated to a specific scent, a sound-generating substance that is universally applicable to a variety of smoking articles can be provided.

[0033] When adding reference symbols to components in each drawing, it should be noted that the same components are given the same symbols as much as possible even if they are displayed in different drawings. In addition, when describing the present disclosure, if it is determined that a detailed description of related known configurations or functions may make the gist of the present disclosure unclear, the detailed description will be omitted.

[0034] 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 clearly defined otherwise. 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.

[0035] 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 be further "coupled," "coupled," or "connected" between each component.

[0036] 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.

[0037] First, some terminology used in the examples that follow will be clarified.

[0038] 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.

[0039] In the following examples, "smoking material" may refer to a material used for smoking. For example, smoking material may include tobacco material, which may include all kinds of materials based on tobacco raw materials, such as ground tobacco leaves, expanded midribs, tobacco shreds (e.g., tobacco shreds, tabular shreds), tobacco sheets (e.g., tabular leaves), etc.

[0040] In the following examples, "puff" refers to a user'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.

[0041] In the following examples, "upstream" or "upstream direction" may mean a direction away from the smoker's mouth, and "downstream" or "downstream direction" may mean a direction toward the smoker's mouth. The terms upstream and downstream may be used to describe the relative positions of elements that make up the aerosol-generating article. For example, in the smoking article 1 shown in FIG. 1, the smoking material portion 12 is located upstream or in the upstream direction of the filter portion 11, and the filter portion 11 is located downstream or in the downstream direction of the smoking material portion 12.

[0042] In the following examples, "longitudinal direction" may mean the direction corresponding to the longitudinal axis of the smoking article.

[0043] Various embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings.

[0044] According to various embodiments of the present disclosure, a smoking article may be provided in which a sound-generating substance is added to a smoking material portion, thereby generating a sound when smoked. The sound-generating substance may include a carbohydrate substance (e.g., monosaccharides, polysaccharides, etc.). Since the specific manner of adding the sound-generating substance may vary, the smoking article may be designed and manufactured in a variety of forms.

[0045] Before describing various forms of smoking articles, in order to facilitate understanding, exemplary smoking articles that may be referenced in various embodiments of the present disclosure will first be described.

[0046] FIG. 1 illustrates an exemplary smoking article 1 to which various embodiments of the present disclosure may refer.

[0047] As shown in Fig. 1, the smoking article 1 may include a filter portion 11 and a smoking material portion 12. However, Fig. 1 shows only components related to the embodiment 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 shown in Fig. 1. In addition, a person skilled in the art will easily understand that the detailed structure of the smoking article 1 may be modified into various forms. The components of the smoking article 1 will be described below.

[0048] The filter unit 11 may include a filter body made of a filter material and a filter wrapper wrapping the filter body, and may be connected to one end of the smoking material unit 12. For example, the filter unit 11 and the smoking material unit 12 may have a rod shape and be aligned in the longitudinal direction, and the upstream end of the filter unit 11 may be connected to the downstream end of the smoking material unit 12. The filter unit 11 and the smoking material unit 12 may be connected by a tipping wrapper, but the scope of the present disclosure is not limited thereto. In some embodiments, the filter unit 11 may also function as a mouthpiece.

[0049] The filter body may include, but is not limited to, cellulose acetate fiber (tow) as a filter material. In some embodiments, the filter body may further include at least one filter material commonly known in the art. For example, the filter body may further include a carbon-containing adsorbent, activated carbon, etc.

[0050] The filter unit 11 may be composed of a single filter or multiple filters. The filter unit 11 may also include a cavity formed by multiple filters, and a capsule containing a flavoring substance may be located inside (e.g., in the cavity) of the filter unit 11. As such, the detailed structure of the filter unit 11 may be modified in various ways, and the technical scope of the present disclosure is not limited by the detailed structure of the filter unit 11.

[0051] The smoking material portion 12 may include a smoking material and a wrapper that wraps the smoking material. The smoking material portion 12 may have a rod shape, but the scope of the present disclosure is not limited thereto.

[0052] The smoking material may include various kinds of materials that generate smoke and / or aerosol or are used for smoking. The smoke and / or aerosol generated by the smoking material may be inhaled into the smoker's mouth through the filter portion 11.

[0053] The smoking material may include, for example, tobacco material. The tobacco material may include, for example, tobacco raw materials such as tobacco leaf slices, tobacco stems, etc., and materials processed therefrom. More specifically, the tobacco material may include crushed tobacco leaves, expanded midribs, tobacco shreds (e.g., tobacco shreds, tabular leaves), tobacco sheets (e.g., tabular leaves), etc.

[0054] In some embodiments, the smoking material may further include additives such as a humectant, a flavoring agent, and / or an organic acid. For example, the humectant may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The humectant may maintain the moisture in the tobacco material at an appropriate level to soften the inherent taste and enrich the amount of atomization. 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.

[0055] In some embodiments, the smoking material may include a clove material. For example, the clove material may include clove powder, clove plant slices, etc., produced by crushing or processing a clove plant (e.g., clove leaves). In this case, a crackling sound (or a crackling sound) is generated during smoking, and an auditory effect is added to the aroma of the clove, providing the smoker with an improved smoking experience.

[0056] In some embodiments, a clove extract (e.g., clove oil) containing a eugenol component may be added as a flavoring agent to enhance the clove aroma. In this case, the flavoring agent may be added in the form of solidified porous granules to improve the aroma preservation of the flavoring agent. For example, the flavoring granules may be added to the filter portion 11, the smoking material portion 12, and / or a cavity formed in the filter portion 11 of the smoking article 1. According to this embodiment, the volatility of the clove extract may be suppressed by preparing the clove extract in granules having a porous structure, and thus the aroma preservation of the flavoring agent may be greatly improved.

[0057] Sound-producing smoking articles according to various embodiments of the present disclosure will now be described.

[0058] The sound generated by the smoking article can provide the smoker with an improved smoking experience by adding an auditory effect during smoking. For example, the sound generated by the smoking article can provide the smoker with a new smoking experience by making the smoker recognize smoking as a recreational activity. Therefore, the inventors of the present disclosure have continuously studied sound-generating substances that can be added to smoking articles. For example, the inventors have continuously studied substances that generate sounds above a standard value when burned. As a result of the research, the inventors have surprisingly confirmed that a carbohydrate substance or a composition containing the same has a characteristic of generating sounds during the combustion process. More specifically, the inventors have confirmed that a carbohydrate substance or a composition thereof has a characteristic of generating sounds when burned by breaking or cracking a crystal structure.

[0059] The use of carbohydrate substances as sound-emitting substances can provide a variety of advantages, including the following: First, carbohydrate substances are easily available and inexpensive, so sound-emitting smoking articles can be manufactured at low cost. For example, carbohydrate substances are significantly cheaper than clove substances, so sound-emitting smoking articles can be manufactured at a lower cost than kretek cigarettes. Second, carbohydrate substances are found in potatoes, wheat, rice, corn, etc., and are substances that people ingest on a regular basis, so they are substances whose safety has already been proven. Therefore, the cost required to prove the safety of sound-emitting smoking articles can be significantly reduced.

[0060] As described above, the sound-generating substance may be a carbohydrate substance or a composition containing the same. Here, the carbohydrate substance may include monosaccharide and / or polysaccharide substances, and the polysaccharide substances may include, but are not limited to, starch, agar, pectin, etc., and may further include various substances.

[0061] In addition, when the sound-generating substance is a composition, the compositional components and composition ratio of the sound-generating substance may be various. For example, the sound-generating substance may further include at least one of glycerin, water, propylene glycol (PG), medium-chain triglyceride (MCTG), and flavoring substances in addition to the carbohydrate substance.

[0062] As a more specific example, the sound-generating material may contain about 15% to 99% by weight of carbohydrate material. Preferably, the sound-generating material may contain about 30% or 40% by weight or more of carbohydrate material, because the sound intensity of the sound-generating material can increase as the content of carbohydrate material increases (see, for example, Experimental Example 2).

[0063] As another example, the sound-generating substance may contain about 5% to 70% by weight of an additive substance such as glycerin, water, propylene glycol (PG), medium-chain triglyceride (MCTG) and / or flavoring substance. For example, the sound-generating substance may contain about 5% to 50% by weight of glycerin, and preferably about 10% to 40% by weight, 15% to 45% by weight, or about 15% to 35% by weight of glycerin. Glycerin can maintain the shape of the substance and increase the sound intensity by increasing the hardness of the sound-generating substance, and experimental results (see Experimental Example 2, etc.) also show that the sound intensity increases as the content of glycerin increases. In addition, glycerin and propylene glycol can be added as moisturizing substances for applications to increase the amount of atomization of smoking articles. Flavoring substances can be added for applications to improve the aroma expression of smoking articles.

[0064] As yet another example, the sound-generating substance may contain about 15% to 90% by weight of carbohydrate substance, about 5% to 45% by weight of glycerin, and about 3% to 43% by weight of water. It has been shown that within such composition ranges, the sound-generating substance has an appropriate hardness and the sound intensity is also improved (see Experimental Examples 1 and 2, etc.).

[0065] Meanwhile, the manner in which the sound-emitting substance is added to the smoking article may vary depending on the embodiment, and in this regard, a detailed description will be given with reference to the drawings from Fig. 2 onwards. In the following description, for the sake of clarity, description of contents that overlap with those described above will be omitted, and for description of components of smoking articles 2 to 4 shown in the following drawings, please refer to the description of Fig. 1.

[0066] First, a smoking article 2 according to a first embodiment of the present disclosure will be described with reference to Figs.

[0067] 2 or 3, in the first embodiment, a sound-generating material 20 processed into particles may be added to a smoking material portion 22 of a smoking article 2. Here, the particle form may include all shapes such as powder, granules, beads, etc. The smoking article 2 is composed of a filter portion 21 and a smoking material portion 22, similar to the smoking article 1 shown in FIG. 1, but as described above, the detailed structure of the smoking article 2 may be modified as much as desired.

[0068] As shown in Fig. 2, particulate sound-generating material 20 (hereinafter referred to as sound-generating particles) may be added inside the smoking material portion 22. For example, the sound-generating particles 20 may be introduced together with tobacco material (e.g. shredded tobacco) during the process of forming a smoking material rod and disposed inside the smoking material portion 22, as will be described in detail later with reference to Fig. 12. However, the scope of the present disclosure is not limited thereto, and the sound-generating particles 20 may be added in other ways.

[0069] Meanwhile, the shape, size, loading amount and / or arrangement of the sound-generating particles 20 may vary depending on the embodiment.

[0070] In some embodiments, the sound-generating particles 20 may have a spherical shape and a diameter (e.g., average diameter) of about 0.2 mm to 4.0 mm. Preferably, the diameter may be about 0.5 mm to 4.0 mm or 0.5 mm to 3.0 mm. More preferably, the diameter may be about 0.8 mm to 2.0 mm. Thus, it is preferable that the sound-generating particles 20 have an appropriate size, because if the size is too small, the sound intensity is reduced, and if the size is too large, the combustibility is reduced and the sound intensity can be reduced (see Experimental Example 1, etc.).

[0071] In some embodiments, the content (addition amount) of the sound-generating particles 20 may be about 1% to 40% by weight or 2% to 35% by weight based on the tobacco substance. Preferably, the content may be about 2% to 30% by weight or 5% to 35% by weight, and more preferably, about 10% to 30% by weight or 15% to 30% by weight. This is because if the content of the sound-generating particles 20 is very low, the sound-generating effect is weak, and if the content is very high, the sound may be very loud or the tobacco substance content may be reduced, resulting in a reduced tobacco taste. However, since the sound-generating particles 20 are relatively cheap compared to the tobacco substance, the higher the content of the sound-generating particles 20, the more the material cost of the smoking article 2 can be reduced. The above-mentioned content range of the sound-generating particles 20 may be similarly applied when the sound-generating substance 20 is added in other forms (e.g., sheets, elongated objects).

[0072] In some embodiments, the plurality of sound-generating particles 20 may have a regular arrangement shape within the smoking material portion 22 (see FIG. 2). For example, the plurality of sound-generating particles 20 may be arranged at regular intervals or evenly distributed rather than being randomly arranged. In such a case, the sound may be generated constantly and the maximum deviation of the sound intensity per puff may be below a reference value (e.g., about 10 dB, 5 dB, etc.), so that a sustained and consistent auditory stimulation effect may be provided during smoking.

[0073] In addition, according to some embodiments of the present disclosure, the sound generation pattern during smoking (e.g., sound volume, sound duration, sound generation interval, sound change, etc.) can be adjusted by changing the size, addition amount, distribution, arrangement interval, arrangement form and / or addition position of the sound-generating particles 20. For example, by adding the sound-generating particles 20 so as to be evenly distributed inside the smoking material portion 22, it is possible to make the sound be generated consistently during smoking. As another example, by adding a large amount of large-sized sound-generating particles 20 only to a specific segment of the smoking material portion 22, it is possible to make a bouncing sound be generated only at a specific time during smoking. As yet another example, as shown in FIG. 3, by adding a smaller amount (e.g., smaller size or number) of sound-generating particles 20 (e.g., adding a smaller amount of particles toward the downstream side) to the downstream segment 23-2 or 23-3 of the multiple segments 23-1 to 23-3 constituting the smoking material portion 22, it is possible to make the sound gradually (even more) quieter as the smoking material is consumed. Conversely, by adding more sound-generating particles 20 to the downstream segments 23-2 or 23-3 (e.g., adding more particles further downstream), the sound can be made to gradually get louder as the smoking material is consumed. In this case, the effect of informing the smoker of the end of smoking can be achieved through the change in sound.

[0074] Meanwhile, according to some other embodiments of the present disclosure, the sound-generating particles 20 may be added to a wrapper wrapping the smoking material. In this case, the basis weight of the wrapper is 30 g / m 2 ~60g / m 2 and preferably 35 g / m 2 ~55g / m 2 , more preferably 40 g / m 2 ~50g / m 2 or 42 g / m 2 ~48g / m 2Thus, it is preferable that the wrapper have a basis weight equal to or greater than the standard value, because the wrapper must be processed to a certain thickness in order for sound-generating particles 20 of an appropriate size (i.e., having an appropriate sound intensity) to be added to the wrapper.

[0075] The smoking article 2 according to the first embodiment of the present disclosure has been described above with reference to Figures 2 and 3. As described above, by adding the particulate sound-generating material 20 to the smoking material portion 22, the smoking article 2 that generates sound can be easily manufactured, and an improved smoking experience can be provided to the smoker.

[0076] A smoking article 3 according to a second embodiment of the present disclosure will now be described with reference to FIGS.

[0077] 4 to 6, in the second embodiment, a sound-generating material 40 processed into a sheet shape may be added to the smoking material portion 32 of the smoking article 3. The smoking article 3 may be composed of a filter portion 31 and a smoking material portion 32, similar to the smoking article 1 shown in FIG 1, but as explained above, the detailed structure of the smoking article 3 may be modified in any manner.

[0078] As shown in the figure, the specific manner in which the sheet-shaped sound-generating material 30 (hereinafter, "sound-generating sheet") is added to the smoking material portion 32 may vary.

[0079] In some embodiments, as shown in Fig. 4, the sound-generating sheet 30 may be added so as to be disposed adjacent to the tobacco sheet 33. For example, the sound-generating sheet 30 and the tobacco sheet 33 may be appropriately mixed (e.g., the sound-generating sheet 30 may be laminated, attached to, or wrapped around the tobacco sheet 33) and added to the smoking material portion 32. The tobacco sheet 33 may be, for example, a reconstituted tobacco sheet such as a tabular leaf, although the scope of the present disclosure is not limited thereto. As another example, the sound-generating sheet 30 and the tobacco sheet 33 may be integrally formed and added to the smoking material portion 32, such as the sound-generating sheet 30 being formed as a part of the tobacco sheet 33.

[0080] In the above embodiment, the thickness ratio of the sound-generating sheet 30 to the tobacco sheet 33 may be about 0.5:1 to 3:1. Preferably, the thickness ratio may be about 1:1 to 3:1, more preferably about 1:1 to 2:1 or 1.2:1 to 1.8:1. As described above, it is preferable that the thickness of the sound-generating sheet 30 is thicker than that of the tobacco sheet 33, because the sound-generating sheet 30 generally has better combustion properties than the tobacco sheet 33. That is, in order to make the combustion rates of the two sheets 30, 33 similar to each other, it is preferable to process the sound-generating sheet 30 to be a little thicker.

[0081] In some other embodiments, as shown in Figure 5, the sound generating sheet 30 may be disposed in a wrapper 34 that wraps the smoking material. For example, the sound generating sheet 30 may form part of the wrapper 34 or may be attached to the inside of the wrapper 34. While Figure 5 shows an example in which the sound generating sheet 30 is attached in the length direction of the smoking article 3, this may vary. For example, as shown in Figure 6, one or more sound generating sheets 30-1 to 30-3 may be attached in the width direction of the smoking article 3.

[0082] Meanwhile, according to some embodiments of the present disclosure, the size (e.g., length, thickness), arrangement position, arrangement interval and / or arrangement form of the sound generating sheet 30 may be changed to adjust the sound generation pattern during smoking. For example, as shown in FIG. 6, the sound generating sheets 30-1 to 30-3 may be arranged at regular intervals to generate sound at regular intervals during smoking. As another example, a smaller sound generating sheet 30 may be arranged in the downstream wrapper 34 area and a larger sound generating sheet 30 may be arranged in the upstream wrapper 34 area so that the sound becomes gradually (even) quieter as the smoking material is consumed. Conversely, a larger sound generating sheet 30 may be arranged in the downstream wrapper 34 area so that the sound becomes gradually (even) louder as the smoking material is consumed. In this case, the effect of informing the smoker of the end of smoking through the change in sound may be achieved.

[0083] The smoking article 3 according to the second embodiment of the present disclosure has been described above with reference to Figures 4 to 6. As described above, by adding the sound-generating material 40 processed into a sheet shape to the smoking material portion 32, the smoking article 3 that generates sound when smoked can be easily manufactured, and an improved smoking experience can be provided to the smoker.

[0084] A smoking article 4 according to a third embodiment of the present disclosure will now be described with reference to FIGS.

[0085] As shown in Fig. 7 to Fig. 9, in the third embodiment, the sound-generating material 40 may be processed into an elongated object shape and added to the smoking material portion 42 of the smoking article 4. Here, elongated includes all object shapes that are thin and long, and may mean, for example, a thin and long cylindrical shape like a toothpick, but is not limited thereto. However, in the following, for ease of understanding, the explanation will be continued on the assumption that the sound-generating material 40 is processed into an elongated cylindrical shape. The smoking article 4 may be composed of a filter portion 41 and a smoking material portion 42, similar to the smoking article 1 shown in Fig. 1, but as described above, the detailed structure of the smoking article 4 may be modified in any manner.

[0086] As shown in the figure, the specific manner in which the sound-generating material 40 (hereinafter, "sound-generating object") processed into the shape of an elongated object is applied to the smoking article 4 may vary.

[0087] In some embodiments, one or more sound generating objects 40 may be disposed within the smokable material portion 42, as shown in Figure 7. For example, the sound generating object 40 may be disposed near the center of the smokable material portion 42. As another example, multiple sound generating objects 40-1, 40-2, etc. may be disposed at designated locations on the smokable material portion 42, as shown in the cross-sectional view of Figure 8.

[0088] In the above-mentioned embodiment, the diameter d2 of the sound generating object 40 may be about 1% to 40% of the diameter d1 of the smoking material portion 42. Preferably, the diameter d2 may be about 2% to 35% or 3% to 30% of the diameter d1 of the smoking material portion 42, and more preferably, about 5% to 20%, 6% to 18%, or 7% to 15%. Thus, it is preferable that the diameter d2 of the sound generating object 40 is set to an appropriate length for the following reasons.

[0089] First, if the diameter d2 of the sound-generating object 40 is very small, it may burn quickly, shortening the duration of the sound, or the sound intensity may decrease due to a reduced content of the sound-generating material 40. Also, if the diameter d2 of the sound-generating object 40 is small and it burns faster than the tobacco material, cigarette ash may be scattered or scattered during smoking, causing inconvenience to the smoker and those around. Therefore, it is preferable that the diameter d2 of the sound-generating object 40 is equal to or greater than a certain length.

[0090] On the other hand, if the diameter d2 of the sound-generating object 40 is too large, the burning property of the sound-generating object 40 may decrease, the sound intensity may decrease, and the tobacco substance content may decrease, resulting in a poor tobacco taste. Therefore, it is preferable that the diameter d2 of the sound-generating object 40 is less than a certain length.

[0091] Also, the area of ​​the sound generating object 40 may be about 1% to 40% of the area of ​​the smoking material portion 42. Preferably, the area of ​​the sound generating object 40 may be about 2% to 35% or 3% to 30% of the area of ​​the smoking material portion 42, and more preferably about 5% to 20%, 6% to 18%, or 7% to 15%. In this way, it is preferable that the area of ​​the sound generating object 40 is set to an appropriate size, and the reason for this is similar to that described above.

[0092] In some other embodiments, as shown in Figure 9, the sound-emitting object 40 may be added to the smoking material portion 42 in a chopped state. In this case, the sound-emitting object 40 may be chopped to a uniform size or may be chopped to different sizes.

[0093] Meanwhile, according to some embodiments of the present disclosure, the size (e.g., length, thickness, volume), arrangement position, arrangement interval and / or arrangement form of the sound-generating object 40 may be changed to adjust the sound generation pattern during smoking. For example, the sound-generating objects 40 may be arranged at regular intervals to generate sound at regular intervals during smoking. As another example, as shown in FIG. 9, a larger amount of sound-generating objects 40 may be arranged in the upstream segment 42-1 of the multiple segments 42-1 to 42-3 constituting the smoking material portion 42, and a smaller amount of sound-generating objects 40 may be arranged in the downstream segments 42-2 or 42-3, so that the sound becomes gradually (further) quieter as the smoking material is consumed. Conversely, a larger amount of sound-generating objects 40 may be arranged in the downstream segments 42-2 or 42-3 to cause the sound to become gradually (further) quieter as the smoking material is consumed. In this case, the effect of informing the smoker of the end of smoking through the change in sound may be achieved.

[0094] The smoking article 4 according to the third embodiment of the present disclosure has been described above with reference to Figures 7 to 9. As described above, by adding the sound-generating material 40 processed into an elongated object shape to the smoking material part 42, the smoking article 4 that generates sound can be easily manufactured, and an improved smoking experience can be provided to the smoker.

[0095] Above, smoking articles 2 to 4 according to the first to third embodiments of the present disclosure have been described with reference to Figs. 2 to 9. Although each embodiment has been described separately, the above-mentioned embodiments can be combined in various forms. For example, two or more sound-generating materials among the sound-generating particles 20, the sound-generating sheet 30, and the sound-generating object 40 can be added to the smoking material portion.

[0096] Furthermore, the smoking articles 2 to 4 described above can generate sound during smoking, and the sound intensity can be about 20 dB to 80 dB, preferably about 40 dB to 70 dB or about 50 dB to 65 dB. Such sound intensity can further improve the smoking experience of the smoker by providing an appropriate level of auditory stimulation during smoking. For reference, the sound intensity of the smoking articles 2 to 4 can be adjusted by changing the size, amount of addition, compositional components and / or composition ratio of the sound-generating substances 20 to 40.

[0097] In addition, in some embodiments, the maximum deviation of the sound intensity per puff of the smoking articles 2 to 4 described above may be about 10 dB or 7 dB or less, and preferably about 5 dB, 3 dB or 1 dB or less. Here, the deviation per puff may be calculated based on the puffs in the middle of smoking (e.g., the third to seventh puffs) excluding the puffs in the early and late stages of smoking (e.g., the first puff and the last puff). Since the deviation of the sound intensity is below the standard value means that a certain sound is continuously generated, the smoking articles 2 to 4 having the sound intensity deviation below the standard value can provide the smoker with a further improved smoking experience. For reference, the deviation of the sound intensity can be adjusted by changing the size, the amount of addition, the composition components, the composition ratio, the arrangement form and / or the arrangement interval of the sound generating materials 20 to 40.

[0098] With respect to the sound intensity and deviation of smoking articles 2 to 4, further reference is made to Experimental Examples 1 and 2.

[0099] Hereinafter, a method for producing the above-mentioned sound-producing substances (eg20 to 40) and smoking articles (eg2 to 4) will be described with reference to Figs. 10 to 12.

[0100] FIG. 10 is an exemplary flow chart showing a method for manufacturing smoking articles 2-4 according to some embodiments of the present disclosure.

[0101] As shown in Fig. 10, the manufacturing method may start with step S20 of manufacturing a sound-generating material, the detailed process of which is shown in Fig. 11.

[0102] As shown in Fig. 11, the sound-generating material can be manufactured through a mixed solution manufacturing step S22, a molding step S24, a washing step S26, and a drying step S28. However, in some other embodiments, some steps can be omitted and additional steps can be added. Each step will be described in detail below.

[0103] In step S22, a mixed solution may be prepared. For example, the components constituting the sound-generating substance (e.g., carbohydrate substances, glycerin, PG, MCTG, flavoring substances, etc.) may be mixed with a solvent (e.g., water, etc.) to prepare the mixed solution. The components constituting the mixed solution and the mixing ratio may vary, which may result in a change in the composition components and / or component ratio of the sound-generating substance. In addition, a stirrer known in the art may be utilized to prepare the mixed solution, but the scope of the present disclosure is not limited thereto.

[0104] In step S24, the mixed solution may be molded into a desired shape using a molding device. For example, the mixed solution may be molded into a bead shape using an injection molding device for manufacturing beads (e.g., an injection molding device using a nozzle with a diameter of 3 mm). However, the scope of the present disclosure is not limited thereto, and the molding device may also mold the mixed solution into a sheet, an elongated object, or the like.

[0105] For reference, when the mixed solution contains a carbohydrate material and a flavoring material (or flavoring liquid), the injection molding machine can also produce beads in a form in which the carbohydrate material contains the flavoring material (eg, in a capsule form).

[0106] Also, in step S24, a process of immersing the product (eg, beads) of the molding device in an MCTG solvent and cooling it can be further performed.

[0107] Meanwhile, as shown in FIG. 11, the manufacturing process of the sound-emitting material may not include a hardening step, which may be understood as a measure to further improve the safety of the sound-emitting material. That is, the safety of the sound-emitting material may be further improved by not adding a hardening agent during the manufacturing of the sound-emitting material. For reference, the problem of reduced hardness due to the absence of a hardening agent may be alleviated by the glycerin contained in the mixed solution. This is because glycerin is a highly viscous material and can act to increase the hardness of the sound-emitting material. However, in some other embodiments, a hardening step may also be performed during the manufacturing of the sound-emitting material.

[0108] In step S26, the result of the molding apparatus may be washed. For example, the result may be washed using a washing solvent such as ethanol. The washing may be performed once or more.

[0109] In step S28, the washed product is dried to produce a sound-generating material. Drying can be performed in a variety of ways, for example, using a rotary type dryer, although the scope of the present disclosure is not limited thereto.

[0110] Meanwhile, the moisture content of the sound-generating material can be adjusted depending on the drying conditions, and the drying conditions can be set in various ways.

[0111] In some embodiments, the drying conditions may be set to a temperature of about 20° C. to 40° C., a relative humidity of about 10% to 40%, and a drying time of 5 hours or more. Here, the temperature, relative humidity, and / or drying time may be adjusted within the above-mentioned numerical ranges. For example, the drying conditions may be set to a temperature of about 23° C., a relative humidity of about 18%, and a drying time of 10 hours or more.

[0112] Further explanation will be given with reference to FIG.

[0113] In step S40, a sound-generating material may be added to the smoking material rod. More specifically, the sound-generating material may be added while filling the wrapping material with tobacco material to form the smoking material rod. For ease of understanding, this step will be described with reference to FIG. 12. For reference, FIG. 12 conceptually illustrates the process of forming a smoking material rod for ease of understanding, and an actual manufacturing method may differ. Also, FIG. 12 assumes that cut tobacco 54 is used as the tobacco material.

[0114] As shown in FIG. 12, a shredded tobacco supplying device 53 supplies shredded tobacco 54 onto a wrapping material 51, and at the same time, a separate supplying device 52 supplies a sound-generating substance 50 in the MD (machine direction) direction (i.e., the length direction of the smoking article). In this way, smoking articles (e.g., 2 to 4) that generate sound at high speed can be manufactured without affecting the operability of the manufacturing process. In addition, the separate supplying device 52 controls the supply of the sound-generating substance 50, so that the arrangement pattern of the sound-generating substance 50 can be easily controlled. For example, the supplying device 52 can make the sound-generating substance 50 be regularly arranged in a rod-shaped shredded tobacco 55 or smoking material rod 56. The supplying device 52 can also control the amount of sound-generating substance 50 to be input.

[0115] The tobacco shreds 54 and the sound-producing material 50 may be wrapped with the wrapping material 51 to form a smoking material rod 56, which may later be cut into a plurality of smoking material portions 56-1, 56-2 (see step S60).

[0116] In step S60, the formed smoking material rod is cut to produce a plurality of smoking material sections, which may correspond to the smoking material sections 22 to 42 described above.

[0117] In step S80, a smoking article may be constructed by connecting the smoking material portion and the filter portion. For example, a smoking article may be constructed by connecting the smoking material portion and the filter portion with a tipping wrapper. The constructed smoking article may correspond to the smoking articles 2 to 4 described above.

[0118] The manufacturing methods for the sound-emitting material and the smoking article have been described above with reference to Figs.

[0119] The configurations and effects of the aforementioned smoking articles 2 to 4 will be described in more detail below through examples and comparative examples. However, the following examples are merely illustrative of some of the smoking articles 2 to 4, and the scope of the present disclosure is not limited to such examples.

[0120] [Example 1] A smoking article having the same structure as smoking article 2 shown in Fig. 2 was manufactured. When manufacturing a cigarette, about 600 mg of cut tobacco and about 40 sound-generating substances manufactured in the form of beads were added, and the sound-generating substances were added so as to have a regular arrangement. The sound-generating substances were manufactured by the method shown in Fig. 11, and the manufactured sound-generating substances were composed of about 33 wt% agar, about 19 wt% pectin, about 29 wt% glycerin and about 19 wt% water, and had particle sizes of about 1.0 mm to 1.25 mm.

[0121] [Example 2] A cigarette similar to that of Example 1 was produced, except that the particle size of the sound-producing substance was about 0.5 mm to 0.75 mm.

[0122] [Example 3] A cigarette similar to that of Example 1 was produced, except that the particle size of the sound-producing substance was about 1.5 mm to 1.75 mm.

[0123] [Example 4] A cigarette similar to that of Example 1 was produced, except that the particle size of the sound-producing substance was about 2.0 mm to 2.25 mm.

[0124] [Example 5] A cigarette similar to that of Example 1 was produced, except that the particle size of the sound-producing material was about 2.5 mm to 2.75 mm.

[0125] [Example 6] The same cigarettes as in Example 1 were prepared, except that the sound producing material consisted of about 27% agar, about 21% pectin, about 32% glycerin and about 20% moisture by weight.

[0126] [Example 7] The same cigarettes as in Example 1 were prepared, except that the sound producing material consisted of about 39% agar, about 21% pectin, about 21% glycerin and about 19% moisture by weight.

[0127] [Example 8] The same cigarettes as in Example 1 were prepared, except that the sound producing material consisted of about 55% agar, about 31% pectin and about 14% moisture by weight.

[0128] [Example 9] The same cigarettes as in Example 1 were prepared, except that the sound producing material consisted of about 15% agar, about 16% pectin, about 48% glycerin and about 21% moisture by weight.

[0129] [Comparative Example 1] The same cigarettes as in Example 1 were prepared, except that the same amount of clove plant pieces were used as the sound-producing material.

[0130] [Comparative Example 2] A cigarette similar to that of Example 1 was prepared, except that no sound-producing substance was added.

[0131] Table 1 below summarizes the cigarette rolling conditions for Examples 1 to 9 and Comparative Examples 1 and 2.

[0132] [Table 1]

[0133] "Experimental Example 1: Measuring sound intensity by particle size" An experiment was conducted to measure the sound intensity of the smoking articles according to Examples 1 to 5 and Comparative Example 1. The experiment was conducted under HC (Health Canada) smoking conditions using an automatic smoking device in a smoking room with a temperature of about 20°C and a humidity of about 62.5%, and the sound intensity was calculated as the average value of five measurements based on 8 puffs per measurement. A BSWA 308 sound level meter was used to measure the sound intensity. The experimental results are shown in Table 2 below.

[0134] [Table 2]

[0135] Referring to Table 2, it is shown that the sound intensity of the smoking article according to the embodiment is significantly higher than that of Comparative Example 1. This shows that the sound generating performance of the sound generating material according to the embodiment is superior to that of the clove material, and that the addition of the sound generating material can produce a smoking article that provides a better smoking experience than a kretek cigarette.

[0136] It has also been shown that the sound intensity generally increases as the average particle size increases. For example, the sound intensity of the smoking articles according to Examples 1 and 3 was higher than that of Example 2, which has an even smaller average particle size. However, in the case of Example 5, which has the largest average particle size, the sound intensity is lower than that of Example 4, which is considered to be a result of the correlation between particle size and flammability. That is, the larger the particle size, the lower the flammability of the sound-generating material, so when the particle size exceeds a certain level, a phenomenon occurs in which the sound-generating effect decreases, and this is considered to be a result of this phenomenon.

[0137] Also, it was shown that the sound intensity deviation of the smoking article according to the embodiment is much smaller than that of Comparative Example 1. This is believed to be because the sound-generating material added to the smoking article has a more regular arrangement than the clove material of Comparative Example 1. This shows that the smoking article according to the embodiment can provide a much better smoking experience than kretek cigarettes.

[0138] "Experimental Example 2: Measuring sound intensity based on material composition" An experiment was conducted to measure the sound intensity of the smoking articles according to Examples 1, 6 to 9. The sound intensity was measured in the same manner as in Experimental Example 1, and the experimental results are shown in Table 3 below. In Table 3 below, the experimental results for Comparative Example 1 are further summarized in the experimental results in Table 2.

[0139] [Table 3]

[0140] Referring to Table 3, it was shown that the sound intensity of the smoking article according to the embodiment is much better than that of Comparative Example 1. As a result, although there is a difference in sound intensity depending on the composition ratio, it can be easily predicted that the performance of the sound-generating material is at least superior to that of the clove material regardless of the composition ratio.

[0141] In addition, the experimental results for Examples 1, 6-9 (excluding 8) show that as the content of carbohydrate substances increases, the sound intensity of the smoking article generally increases, confirming that carbohydrate substances act as a factor in generating sound.

[0142] Further, referring to the experimental results of Example 8, it is shown that when glycerin is added at a certain ratio, the sound intensity of the smoking article is further increased. For example, even though the sound-generating material according to Example 8 contains the most carbohydrate material, the sound intensity is lower than that of the other Examples. This is believed to be because glycerin acts to increase the hardness of the sound-generating material.

[0143] Considering the above experimental results, it is found that carbohydrate substances or compositions containing the same are better sound-generating substances than clove substances, and the sound-producing performance of the sound-generating substances can be adjusted by adjusting the content of carbohydrate substances. It is also found that it is preferable to add an appropriate amount of glycerin during the preparation of the sound-generating substances.

[0144] "Experimental Example 3: Evaluation of manufacturing workability" In order to evaluate the effect of the addition of a sound-emitting substance on manufacturing workability, the manufacturing workability of the smoking article according to Example 1 was compared with that of Comparative Example 2. Although the sound-emitting substance was supplied by a separate supply device (eg52) as shown in Figure 12, no significant difference was observed in the manufacturing speed and defect rate of the smoking article. This shows that adding the sound-emitting substance in the manner shown in Figure 12 has almost no effect on the manufacturing workability of the smoking article.

[0145] "Experimental Example 4: Physical Property Analysis" In order to investigate the effect of the addition of a sound-generating substance on the physical properties of a smoking article, experiments were conducted to measure the physical properties of the smoking articles according to Example 1 and Comparative Example 2. The measurement items and results are shown in Table 4 below. For reference, in Table 4 below, the air dilution ratio may refer to the volume ratio between the total volume of the final mainstream smoke and the external air flowing into the smoking article.

[0146] [Table 4]

[0147] As shown in Table 4, the addition of the sound-generating material has almost no effect on the change in physical properties, except for a slight increase in the weight of the smoking article. This shows that the sound-generating material according to the embodiment has a positive effect of adding an auditory effect when smoking.

[0148] "Experimental Example 5: Analysis of Smoke Components" An experiment was conducted to analyze the smoke components of the smoking articles according to Example 1 and Comparative Example 2. Specifically, the smoke components of the mainstream smoke of the smoking articles according to Example 1 and Comparative Example 2 were analyzed, and the smoking experiment was conducted under HC (Health Canada) smoking conditions using an automatic smoking device in a smoking room with a temperature of about 20°C and a humidity of about 62.5%. Smoke collection for component analysis was repeated three times for each sample, with 8 puffs per collection, and the average values ​​for the three collection results are shown in Table 5 below.

[0149] [Table 5]

[0150] Referring to Table 5, it is shown that the nicotine and tar transfer amounts of Example 1 are almost similar to those of Comparative Example 2, which means that the overall smoking sensation (e.g., tobacco taste) felt by the smoker is almost similar. This shows that the smoking article according to the embodiment only adds an auditory effect through the sound-generating substance and does not affect other parts, which can provide the smoker with an improved smoking experience.

[0151] The configurations and effects of the above-mentioned smoking articles 2 to 4 have been described in more detail above through various examples and comparative examples.

[0152] Although the embodiments of the present disclosure have been described above with reference to the accompanying drawings, those skilled in the art to which the present disclosure pertains can understand that the present disclosure can be embodied in other specific forms without changing the technical idea or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and are not limiting.
