Description

A filter for a smoking article that generates sound and a smoking article including the same {FILTER FOR SOUND-GENERATING SMOKING ARTICLE AND SMOKING ARTICLE INCLUDING THE SAME}

The present disclosure relates to a filter for a smoking article that generates sound and a smoking article including the same. More specifically, it relates to a filter for a smoking article that can provide a smoker with an improved smoking experience by providing a more auditory effect when smoking, and a smoking article including the same.

Research is being actively conducted on technologies that can provide a differentiated smoking experience through smoking products. However, most of the existing studies focus on taste, smell, and/or visual differentiation among the various senses that consumers can feel, and research on auditory differentiation is quite minimal compared to that. For example, most existing studies are focused on flavor processing technology (taste/olfactory differentiation) and vapor volume increase technology (visual differentiation).

Meanwhile, an example of a smoking article related to auditory differentiation is Indonesian kretek cigarettes. When smoking Kretek cigarettes, the clove material burns and produces a crackling sound. The name "Kretek" also comes from this characteristic. .

However, since Kretek cigarettes are cigarettes with clove substances added to create a clove flavor (i.e. for taste/olfactory differentiation), it is difficult to strictly view them as a product of research for auditory differentiation. In addition, users who are not familiar with the scent of clove may feel quite averse to Kretek cigarettes.

The technical problem to be solved through several embodiments of the present disclosure is to provide a filter for a smoking article that can provide a smoker with an improved smoking experience by providing an additional auditory effect when smoking, and a smoking article including the same. .

Another technical problem to be solved through some embodiments of the present disclosure is to provide a filter for smoking articles that is a filter that generates sound and can be universally applied to various smoking articles.

According to various embodiments of the present disclosure, a filter for a smoking article that can further provide an auditory effect when smoking can be provided. The provided filter for smoking articles can provide an auditory refreshing feeling to the smoker by generating bubble sounds through an acid-base reaction. In addition, the provided filter for smoking articles can provide a unique smoking experience by allowing smokers to perceive smoking as a recreational activity. Hereinafter, the filter for smoking articles according to the embodiments will be described in detail, but for convenience of explanation, “filter for smoking articles” will be abbreviated as “filter.”

1 is a diagram for explaining the sound generation principle and design guidelines of the filter 1 according to some embodiments of the present disclosure.

As shown in Figure 1, the sound generating principle of the filter 1 is based on acid-base reaction. Specifically, gas 16 may be generated as the acid substance 12 (“A”cid) and the base substance 13 (“B”ase) react in the internal space 14 of the filter 1, which is a liquid. As the gas 15 is generated in the form of bubbles within (15), sound (i.e., bubble sound) may be generated. Since the sound generated in this way is similar to the sound of bubbles in carbonated drinks, it can provide an auditory refreshing feeling to smokers.

In order for a bubble sound to be generated, an acid-base reaction must occur within the liquid 15, so at least one of the acid substance 12 or the base substance 13 is designed to be contained in the liquid 15 (e.g. the acid or base substance) It may be preferable to exist in the form of an aqueous solution, an acid or base substance to exist in the form of a precipitate in a liquid solvent, etc.). Alternatively, it may be desirable to design the acid substance 12 and the base substance 13 in a solid state to meet a predetermined liquid (e.g. distilled water).

In addition, since the generation of sound must be withheld until smoking (i.e., the acid-base reaction must not occur), the two reactants of the acid-base reaction (i.e., acid substance 12 and base substance 13) must interact with each other within the filter (1). It may be desirable to design for isolation.

So far, with reference to FIG. 1, the principle of sound generation and desirable design guidelines of the filter 1 have been briefly explained. Hereinafter, specific and various embodiments of the sound generating filter 1 according to the above-described design guidelines will be described in detail with reference to the drawings of FIG. 2 and below.

First, the filter 2 according to the first embodiment of the present disclosure will be described with reference to FIG. 2.

As shown in FIG. 2, the filter 2 according to this embodiment may include a filter material, a capsule 21 filled with a liquid containing a first material, and a solid second material 22. However, only components related to the embodiment of the present disclosure are shown in FIG. 2 . Accordingly, a person skilled in the art to which this disclosure pertains can recognize that other general-purpose components may be further included in addition to the components shown in FIG. 2 . For example, the filter 2 may further include a filter wrapper surrounding the filter material or filter plug.

The filter material may perform a filtration function for smoke and/or aerosols. Examples of filter materials include cellulose acetate fiber, paper, adsorbent containing carbon, activated carbon, etc., but the scope of the present disclosure is not limited thereto.

Next, the capsule 21 may be a structure that surrounds a liquid containing the first material with a film, and may serve to isolate the first material from the second material 22 to suspend the acid-base reaction. there is. The capsule 23 may have a spherical or cylindrical shape, but is not limited thereto. Figure 2 shows as an example that one capsule 21 is inserted into the filter 2, but the number of capsules 21 may be plural.

A second solid material 22 may be disposed around the capsule 21. For example, the second material 22 in the form of granules may be disposed around the capsule 21. Here, the granule form may encompass forms such as powder, particles, beads, and granules. Since the second material 22 is disposed around the capsule 21, an acid-base reaction can easily occur as the capsule 21 is broken. More specifically, as the capsule 21 is broken, the first material is released, and the released first material meets the surrounding second material 22 and can easily cause an acid-base reaction. Sound can be generated by gas (bubbles) generated through.

The first material and the second material 22 are reactants of an acid-base reaction, and FIG. 2 shows an example where the first material is an acid material and the second material 22 is a basic material (see shading). Of course, the first material may be a base material and the second material 22 may be an acid material. Hereinafter, for convenience of understanding, the explanation will be continued assuming that the first material is an acid and the second material 22 is a base. However, the scope of the present disclosure is not limited thereto.

The acid substance may be, for example, citric acid, acetic acid, etc., but is not limited thereto.

Additionally, the base material may be, for example, a carbonate containing sodium bicarbonate (baking soda), calcium carbonate, etc., but is not limited thereto.

Meanwhile, acid substances, base substances and/or acid-base reactions can be designed and selected in various ways, and this may vary depending on the embodiment.

In some embodiments, the acid-base reaction may be a reaction that produces carbon dioxide. That is, acid substances and base substances that generate carbon dioxide during reaction can be applied to the filter 2. Since carbon dioxide is a gas whose safety has been verified, this acid-base reaction can clearly ensure the safety of smokers and significantly reduce the cost required for safety verification when manufacturing the filter 2.

Additionally, in some embodiments, the acid-base reaction may be a reaction that does not produce gases other than carbon dioxide. In this case, the safety of smokers can be more clearly guaranteed.

Additionally, in some embodiments, the syn-base reaction may be endothermic. That is, acid substances and base substances that absorb surrounding heat during reaction can be applied to the filter 2. In this case, since the smoke and/or aerosol passing through the filter 2 can be cooled, various advantages can be obtained. For example, the length of the cooling section can be shortened, thereby improving design freedom for the smoking article. Additionally, the overall smoking experience may be improved due to the cooling effect on the smoke and/or aerosol.

Additionally, in some embodiments, the acid material may be citric acid and the base material may be carbonate. For example, the base material may be sodium bicarbonate. In this case, an acid-base reaction may occur according to Scheme 1 below. Since the acid-base reaction according to Scheme 1 produces only carbon dioxide, the safety of smokers can be clearly guaranteed. In addition, since the acid-base reaction according to Scheme 1 is an endothermic reaction, a cooling effect on aerosol can also be guaranteed.

[Scheme 1]

C ₆ H ₈ O ₇ (aq) + 3NaHCO ₃ (aq) + H ₂ O(l) → Na ₃ C ₆ H ₅ O ₇ (s) + 3CO ₂ (g) + 3H ₂ O(l)

So far, the filter 2 according to the first embodiment of the present disclosure has been described with reference to FIG. 2. Hereinafter, the filter 3 according to the second embodiment of the present disclosure will be described with reference to FIG. 3. For clarity of the present disclosure, description of content that overlaps with the previous embodiments will be omitted.

As shown in FIG. 3, the filter 3 according to this embodiment includes a filter material, a capsule 31 filled with a liquid containing an acid material, and a base material 32 coated on the outer surface of the capsule 31. It can be included. As mentioned above, it goes without saying that the capsule 31 may be filled with a liquid containing a basic substance, and the outer surface of the capsule 31 may be coated with an acid substance.

In this embodiment, as the capsule 31 is broken, an acid material is released, and the released acid material causes an acid-base reaction with the coated base material, thereby generating sound.

So far, the filter 3 according to the second embodiment of the present disclosure has been described with reference to FIG. 3. Hereinafter, the filter 4 according to the third embodiment of the present disclosure will be described with reference to FIG. 4.

As shown in FIG. 4, the filter 4 according to this embodiment includes a filter material, a first capsule 41 filled with a liquid containing an acid material, and a second capsule filled with a liquid containing a base material ( 42) may be included. At this time, it may be desirable for the first capsule 41 and the second capsule 42 to be placed close to each other so that the acid-base reaction can occur smoothly.

In this embodiment, as the first capsule 41 and the second capsule 42 are broken, acid substances and base substances are released from each capsule 41 and 42, and the released substances cause an acid-base reaction. As a result, sound can be generated.

Meanwhile, in some embodiments, the filter 4 may include a single capsule formed with a plurality of liquid-filled spaces isolated from each other. At this time, the first liquid filling space may be filled with a liquid containing an acid substance, and the second liquid filling space may be filled with a liquid containing a base substance. Even in this case, sound may be generated as an acid-base reaction occurs when the capsule is broken.

So far, the filter 4 according to the third embodiment of the present disclosure has been described with reference to FIG. 4. Hereinafter, filters 5 to 9 according to the fourth embodiment of the present disclosure will be described with reference to FIGS. 5 to 8.

As shown in FIGS. 5 to 8, this embodiment relates to a filter (e.g. 5) using a directional capsule (e.g. 51). Here, a directional capsule (e.g. 51) refers to a capsule designed/manufactured to release liquid in a specific direction, and in this case, the specific direction may be one or more directions. Note that the directional capsule (e.g. 51) may be manufactured in any way, and that the shape of the directional capsule (e.g. 51) shown in the drawings below in FIG. 5 may not be related to its actual shape. In other words, the directional capsule (e.g. 51) may be manufactured to have any shape as long as it has the function of releasing liquid in a specific direction when crushed.

In this embodiment, methods of utilizing the directional capsule (e.g. 51) may vary.

As an example, as shown in FIG. 5, when the filter 5 includes an aromatic capsule 51 filled with a liquid containing an acid substance and a solid base substance 52, the aromatic capsule 51 The base material 52 may be disposed in the liquid discharge direction. In this case, the occurrence probability and intensity of the acid-base reaction are increased, and a sound generating filter 5 with high reliability and excellent sound intensity can be manufactured.

As another example, as shown in Figure 6, when the filter 6 includes an aromatic capsule 61 filled with a liquid containing an acid substance and a capsule 62 filled with a liquid containing a base substance, The capsule 62 may be disposed in the liquid discharge direction of the directional capsule 61. Even in this case, the occurrence probability and occurrence intensity of the acid-base reaction are increased, so that the sound generating filter 6 with high reliability and excellent sound intensity can be manufactured.

As another example, as shown in FIG. 7, the filter 7 includes a first directional capsule 71 filled with a liquid containing an acid substance and a second directional capsule 72 filled with a liquid containing a base substance. ), the second directional capsule 72 may be disposed in the liquid discharge direction of the first directional capsule 71, and the first directional capsule 71 may be disposed in the liquid discharge direction of the second directional capsule 72. This can be placed. In this case, the occurrence probability and occurrence intensity of the acid-base reaction are further increased, so that the sound generating filter 7 with more reliability and excellent sound intensity can be manufactured.

As another example, as shown in FIG. 8, the filter 8 includes a first aromatic capsule 81 and a second aromatic capsule 82 filled with a liquid containing an acid substance, and a solid base substance 83. ), the base material 83 may be disposed in the liquid discharge direction of the two directional capsules 81 and 82. For example, a base material 83 is disposed between the two directional capsules 81 and 82, and the liquid discharge direction of the two directional capsules 81 and 82 may be designed (arranged) to face the base material 83. In this case, the occurrence probability and occurrence intensity of the acid-base reaction are further increased, so that the sound generating filter 8 can be manufactured with more reliability and excellent sound intensity.

So far, filters 5 to 9 according to the fourth embodiment of the present disclosure have been described with reference to FIGS. 5 to 8. According to the above, the probability and intensity of the acid-base reaction can be increased by using the aromatic capsule (e.g. 51). Accordingly, sound generating filters 5 to 8 that are highly reliable and have excellent sound intensity can be easily manufactured.

Meanwhile, the description has been made so far on the assumption that the filter (e.g. 2) has a single segment structure, but the filter (e.g. 2) may also have a multi-segment structure. For example, the filter (e.g. 2) may include a plurality of filter segments and may further include a cavity formed between the plurality of filter segments. When the filter (e.g. 2) consists of a plurality of segments, the acid material and the base material may be placed together in the same segment, or the acid material and the base material may be placed in different segments.

For example, as shown in Figure 9, the filter 9 includes a first filter segment 93, a second filter segment 95 and a cavity 94 formed between the two filter segments 93 and 95. Let's assume that we do. In this case, a capsule 91 filled with a liquid containing an acid substance and a solid base substance 92 may be placed in the cavity 94. Alternatively, the capsule 91 may be disposed in the cavity 94 and the base material 92 may be disposed in the filter segments 93 and 95.

As another example, as shown in Figure 10, the filter 10 includes a first filter segment 103, a second filter segment 105, and a cavity 104 formed between the two filter segments 103 and 105. Let's assume that we do. In this case, an aromatic capsule 101 filled with a liquid containing an acid substance is disposed in the cavity 104, and a solid base substance 102 is placed in the filter segment 103 located in the liquid discharge direction of the aromatic capsule 101. This can be placed. Alternatively, a capsule (not shown) filled with a liquid containing a base material (e.g. 102) may be placed on the filter segment 103 located in the liquid discharge direction. Alternatively, directional capsules (e.g. 101) filled with a liquid containing an acid substance are disposed in the two filter segments (103, 105), and a solid base substance (102) or base substance (e.g. 102) is placed in the cavity (104). A capsule (not shown) filled with a liquid containing may be placed. At this time, the liquid discharge direction of each directional capsule (e.g. 101) may be designed to face the cavity 104.

So far, filters 2 to 10 according to various embodiments of the present disclosure have been described with reference to FIGS. 2 to 10 . According to the above description, filters 2 to 10 that generate sound (i.e., bubble sound) can be easily manufactured using the principle of gas (bubble) generation by acid-base reaction. These filters 2 to 10 can provide smokers with an improved or unique smoking experience by providing an additional auditory effect when smoking. For example, the sound of bubbles can provide an auditory refreshing feeling to smokers.

Additionally, by utilizing materials unrelated to clove flavor, a sound generating filter that can be universally applied to various smoking articles can be manufactured. In addition, through this sound-generating filter, sound-generating smoking articles for smokers who are not familiar with clove scent can be easily manufactured, and sound-generating smoking articles of heating type rather than combustion type can also be easily manufactured.

Hereinafter, the smoking article 11 that can generate sound during smoking by including the above-mentioned filters 2 to 10 will be described with reference to FIG. 11.

11 is an example flow diagram illustrating a smoking article 11 according to some embodiments of the present disclosure.

As shown in FIG. 11 , smoking article 11 may include a filter portion 111 and a smoking material portion 112 . However, only components related to the embodiment of the present disclosure are shown in FIG. 11 . Accordingly, a person skilled in the art to which this disclosure pertains can recognize that other general-purpose components may be included in addition to the components shown in FIG. 11 . Additionally, those skilled in the art can easily understand that the detailed structure of the smoking article 11 can be modified into various forms. Hereinafter, each component of the smoking article 11 will be described.

The filter unit 111 may be an element corresponding to the filters 2 to 10 described above with reference to FIGS. 2 to 10. The filter unit 111 is located downstream of the smoking material unit 112 and can perform a filtration function for smoke and/or aerosol generated in the smoking material unit 112, and may cause hearing loss during smoking through an acid-base reaction. Additional effects can be added. The filter unit 111 may further include a filter wrapper surrounding the filter material or filter plug.

As shown, the filter section 111 may be connected to the downstream end of the smoking material section 112. For example, the filter section 111 and the smoking material section 112 have a rod shape and are aligned in the longitudinal axis direction, and the upstream end of the filter section 111 is connected to the downstream end of the smoking material section 112. can be connected The filter unit 111 and the smoking material unit 112 may be connected by a tipping wrapper, but the scope of the present disclosure is not limited thereto. In some embodiments, the filter unit 111 may also serve as a mouthpiece.

The filter unit 111 may have a single segment or multi-segment structure. For example, the filter unit 111 may include a cavity formed by multiple filter segments, and a capsule containing a flavor material may be located inside the filter unit 111 (e.g. the cavity). As such, the detailed structure of the filter unit 111 may be modified in various ways, so the technical scope of the present disclosure is not limited by the detailed structure of the filter unit 111.

Next, the smoking material unit 112 may be located upstream of the filter unit 111 to generate smoke and/or aerosol. For example, the smoking material portion 112 may include smoking material and generate smoke and/or aerosol as the smoking material is burned or heated. The generated smoke and/or aerosol may be inhaled into the smoker's mouth through the filter unit 111. The smoking material portion 112 may further include a wrapper surrounding the smoking material.

Smoking materials may include a variety of substances that generate smoke and/or aerosols or are used for smoking. For example, smoking materials may include tobacco materials. Tobacco materials may include, for example, tobacco raw materials such as tobacco leaf pieces, tobacco stems, etc., as well as materials processed therefrom. As a more specific example, the tobacco material may include crushed tobacco leaves, expanded stems, tobacco cut fillers (e.g. tobacco leaf cut fillers, leaf cut fillers), tobacco sheets (e.g. leaf cut sheets), etc.

In some embodiments, the smoking material may further include additives such as humectants, flavoring agents, and/or organic acids. 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. A humectant can maintain the moisture in the tobacco material at an appropriate level, softening the inherent taste and enriching the amount of vaporization. Additionally, 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.

Additionally, in some embodiments, the smoking material portion 112 may further include a sound generating material that generates sound when smoking. The sound generating material may be, for example, a carbohydrate material (e.g. monosaccharide, polysaccharide, etc.) that generates combustion sound. In this case, a sound is also generated from the smoking material unit 112 when smoking, thereby providing the smoker with an improved smoking experience. Below, the exemplified sound generating materials will be explained in detail.

The inventors of the present disclosure have conducted continuous research on sound-generating substances that can be added to smoking articles. For example, the present inventors have conducted continuous research on materials that generate sounds above the standard level when burned. As a result of the study, surprisingly, the present inventors were able to confirm that the carbohydrate material or the composition containing the same has the characteristic of producing sound during the combustion process. More specifically, the present inventors were able to confirm that the carbohydrate material or its composition has the property of generating sound when the crystal structure is broken or cracked when burned.

Using carbohydrates as sound generating materials can provide the following various advantages. First, because carbohydrate materials are commonly available and inexpensive, sound-producing smoking articles can be manufactured at low cost. For example, because carbohydrate materials are much cheaper than clove materials, it is possible to manufacture sound-generating smoking articles at a lower cost than kretek cigarettes. Second, carbohydrate substances are substances that people consume on a daily basis, including potatoes, wheat, rice, corn, etc., so their safety has already been verified. Accordingly, the cost required to verify the safety of sound-generating smoking articles can be greatly reduced.

As previously mentioned, the sound generating material may be a carbohydrate material or a composition containing the same. Here, the carbohydrate material may include monosaccharide and/or polysaccharide material, and the polysaccharide material may include, for example, starch, agar, pectin, etc., but is not limited thereto and may include various types of substances. Additional substances may be included.

Additionally, when the sound generating material is a composition, the composition and composition ratio of the sound generating material may vary. For example, the sound generating material may further include at least one of glycerin, moisture, propylene glycol (PG), medium chain fatty acid triglyceride (MCTG), and flavoring material in addition to the carbohydrate material.

For a more specific example, the sound generating material may include about 15% to 99% carbohydrate material by weight. Preferably, the sound-generating material may contain about 30% or more than 40% by weight of carbohydrate material, because the sound intensity of the sound-generating material may increase as the content of the carbohydrate material increases.

As another example, the sound-generating material may contain about 5% to 70% by weight of added substances such as glycerin, moisture, propylene glycol (PG), medium chain fatty acid triglyceride (MCTG), and/or flavoring substances (i.e., flavoring agents). It can be included. For example, the sound producing material may include about 5% to 50% by weight glycerin, preferably about 10% to 40% by weight, 15% to 45% by weight, or about 15% to 35% by weight. It may contain glycerin. Glycerin can maintain the shape of the material and increase the sound intensity by increasing the hardness of the sound generating material. Experimental results also showed that the sound intensity increased as the glycerin content increased. Additionally, glycerin and propylene glycol are moisturizing substances and may be added to increase the amount of atomization of the smoking article 11. Flavoring substances may be added to improve the flavor appearance of the smoking article 11.

As another example, the sound-generating material may include about 15% to 90% carbohydrate material, about 5% to 45% glycerin, and about 3% to 43% moisture by weight. Within this composition range, the sound generating material was found to have appropriate hardness and the sound intensity was also improved.

The above-mentioned sound generating material involves the process of preparing a solution containing a carbohydrate material or its composition, the process of molding the prepared solution into an appropriate form (e.g. the form of granules, sheets, etc.), and the process of washing and drying the molded result. However, the scope of the present disclosure is not limited thereto. For reference, the solution preparation process may be performed through a known stirrer, and the molding process may be performed through a known injection molding device.

When the sound-generating material is manufactured in the form of granules, the manufactured sound-generating material may be introduced into the smoking material portion 112. For example, a sound-generating material may be added to the smoking material unit 112 along with a tobacco material. However, the shape, size, addition amount, and/or arrangement of the sound generating material may vary depending on the embodiment.

In some embodiments, the sound-producing material has a spherical-like shape and can have 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. In this way, it may be desirable for the sound generating material to have an appropriate size, because if the size is too small, the sound intensity is reduced, and if the size is too large, the sound intensity may be reduced due to poor combustibility.

Additionally, in some embodiments, the content (added amount) of the sound generating material may be about 1% to 40% by weight or 2% to 35% by weight relative to the tobacco material. Preferably, the content may be about 2% to 30% by weight or 5% to 35% by weight, more preferably, about 10% to 30% by weight or 15% to 30% by weight. It can be. This is because if the content of the sound generating material is too small, the sound generating effect may be minimal, and if the content is too high, the sound may be too loud or the taste of the tobacco may be reduced due to the reduced content of the tobacco material. However, since sound-generating materials are relatively cheaper than tobacco materials, the material cost of the smoking article 11 can be reduced as the content of the sound-generating materials increases. The content range of the sound-generating material described above can be similarly applied even when the sound-generating material is added in another form (e.g. sheet, elongated object).

Additionally, in some embodiments, the sound generating material may have a regular arrangement within the smoking material portion 112. For example, a plurality of sound generating materials may not be arranged randomly but may be arranged at regular intervals or evenly distributed. In this case, the sound may be generated consistently or the maximum deviation of the sound intensity for each puff may be below the standard value (e.g. about 10 dB, 5 dB, etc.), so continuous and consistent auditory stimulation can be provided to the smoker while smoking.

In addition, according to some embodiments of the present disclosure, the sound generation pattern (e.g. sound volume, sound duration) during smoking is changed by changing the size, addition amount, distribution, arrangement interval, arrangement type, and/or addition location of the sound generating material. , sound generation interval, sound change pattern, etc.) can be adjusted. For example, by adding a sound generating material to be evenly distributed inside the smoking material portion 112, sound can be generated consistently during smoking. As another example, by adding a large amount of a large sound-generating material only to a specific segment of the smoking material portion 112, the popping sound can be generated only at a specific time during smoking. As another example, a smaller amount (e.g. smaller size or smaller number) of sound-generating material is added to the downstream segment among the plurality of segments constituting the smoking material portion 112 (e.g. a smaller amount of particles is added toward the downstream side). By adding it, the sound can become increasingly quiet as the smoking material is used up. Conversely, by adding a larger amount of sound-generating material to the downstream segment (e.g., adding a larger amount of particles toward the downstream side), the sound can be made to become increasingly louder as the smoking material is used up. In this case, the effect of informing the smoker of the end of smoking can be achieved through a change in sound.
