[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0049] Figure 1 This is a schematic diagram illustrating the structure of an aerosol-generated article according to one embodiment.

[0050] The present invention provides an aerosol-generating article 100, comprising: a first portion 110 including a combustible heat source containing a flavoring element; a second portion 120 including a tobacco element; and a third portion 130 including a filter element, wherein the first portion 110, the second portion 120, and the third portion 130 are arranged sequentially along the length direction of the aerosol-generating article 100. Additionally, in embodiments, the aerosol-generating article 100 may further include a first wrapping paper 140 and a second wrapping paper 150.

[0051] Reference Figure 1 The first part 110, the second part 120, and the third part 130 can be arranged sequentially along the length of the aerosol generating article 100. Heat generated from a combustible heat source disposed in the first part 110 can be transferred to the second part 120. Aerosols can be generated in the second part 120 by the heat, and the aerosols can be transferred to the user via the third part 130.

[0052] Part 110 may include a combustible heat source. The combustible heat source can generate heat by being ignited and burning. The generated heat can be transferred to the aerosol-generating material in the aerosol-generating article 100, thereby generating an aerosol. The combustible heat source may be a heat source composed of carbon. Preferably, the combustible heat source may be a heat source composed of charcoal. Additionally, the combustible heat source may also include an additive. For example, the additive may be at least one of a combustion improver, an ignition agent, a sintering aid, and a binder.

[0053] Combustible heat sources may include fragrance elements. In the manufacture of combustible heat sources, fragrance elements can be added to the heat source to incorporate fragrance. For example, a combustible heat source can be formed by mixing a material of the combustible heat source with a fragrance liquid containing a fragrance substance. Alternatively, after the combustible heat source is formed, it can be immersed in a fragrance liquid. However, this is not necessarily the only option.

[0054] The flavoring element may contain flavoring substances. Flavoring substances may be selected from the group consisting of free tobacco substances, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, balsam bark, sandalwood, bergamot, geranium, honey extract, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, anise, cognac, jasmine, chamomile, menthol, ylang-ylang, sage, spearmint, ginger, coriander, coffee, and combinations thereof, but are not necessarily limited thereto. Preferably, the flavoring element may contain flavoring substances selected from the group consisting of free tobacco substances, licorice, sucrose, fructose syrup, cocoa, coffee, and combinations thereof. More preferably, the flavoring element may include tobacco substances.

[0055] The fragrance element produces a scent after a combustible heat source is ignited. Because conventional combustible heat sources ignite and undergo surface combustion, they do not exhibit the characteristics of a normal combustion flame. Therefore, it is difficult for users to confirm whether the combustible heat source is ignited. However, since the aerosol generating article 100 of the present invention includes a combustible heat source, and the combustible heat source contains a fragrance element, when the combustible heat source is ignited and burns, the fragrance element can produce a scent through the heat generated by the combustion. Therefore, users can easily confirm that the combustible heat source has been ignited by inhaling the produced scent.

[0056] The second part 120 can be configured to be adjacent to the first part 110. For example, the first part 110 can be configured upstream of the aerosol generating article 100, and the second part 120 can be configured downstream of the aerosol generating article 100 compared to the first part 110.

[0057] Here, the terms "upstream" and "downstream" refer to the portion of the aerosol generating article 100 from the outside to the inside when a user inhales air using the aerosol generating article 100, which is called "upstream," and the portion of the aerosol generating article 100 from the inside to the outside, which is called "downstream." The terms "upstream" and "downstream" are terms used to indicate the relative position or direction between the parts or segments constituting the aerosol generating article 100.

[0058] Part 2, 120, may include tobacco elements. The tobacco elements may contain at least one of aerosol-generating substances and tobacco substances. For example, the aerosol-generating substances may contain at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. For example, the tobacco substances may include at least one of cut tobacco, flat tobacco, tobacco leaves, puffed tobacco, and nicotine extract. The tobacco substances may include nicotine.

[0059] For example, the second portion 120 may include glycerin-impregnated flat tobacco leaves. The combustible heat source of the first portion 110 is ignited and burned, and the resulting heat is transferred to the second portion 120, generating an aerosol in the glycerin-impregnated flat tobacco leaves. However, the invention is not necessarily limited to the above.

[0060] The third part 130 can be configured to be adjacent to the second part 120. For example, the second part 120 can be configured upstream of the aerosol generating article 100, and the third part 130 can be configured downstream of the aerosol generating article 100 relative to the second part 120.

[0061] The third part 130 may include a filter element. The filter element may be a cellulose acetate filter. The shape of the third part 130 is not limited. For example, the third part 130 may be a cylindrical rod or a hollow tubular rod. Alternatively, the third part 130 may be a recessed rod. If the third part 130 consists of multiple segments, at least one of the segments may be made into different shapes.

[0062] The third part 130 can be made to produce a fragrance. As an example, a fragrance liquid can be sprayed into the third part 130, or a separate fiber coated with a fragrance liquid can be inserted into the interior of the third part 130.

[0063] Additionally, the third part 130 may also include a cooling element. The cooling element may include a cooling substance for cooling the airflow passing through the first part 110 and the second part 120. The cooling element may be made of a polymer or a biodegradable polymer and may have a cooling function. For example, the cooling element may be made of pure polylactic acid (PLA), but is not limited thereto.

[0064] Alternatively, the cooling element can be made of a cellulose acetate filter with multiple perforations. However, the cooling element is not limited to the examples above; it is applicable without limitation to any material capable of performing the function of cooling aerosols. For example, the cooling element can be a pipe filter or a branch pipe filter including a hollow section.

[0065] The aerosol-generating article 100 may also include at least one of a first wrapping paper 140 and a second wrapping paper 150.

[0066] The first wrapping paper 140 may surround at least a portion of the first part 110 and the second part 120. For example, the first wrapping paper 140 may be a thermally conductive wrapping paper. Preferably, the first wrapping paper 140 may be an aluminum film. When the first part 110 is ignited and burns, the heat generated in the first part 110 can be directly transferred to the second part 120, and the heat generated in the first part 110 can also be transferred to the second part 120 through the first wrapping paper 140. For example, the first wrapping paper 140 may have a thickness of approximately 50 W / m². -1 / K -1 Approximately 500Wm -1 / K -1 Thermal conductivity.

[0067] The second wrapping paper 150 may surround the first portion 110, the second portion 120, and the third portion 130. For example, the second wrapping paper 150 may be formed from cellulose roll paper. However, the invention is not necessarily limited thereto.

[0068] Additionally, the aerosol-generating article 100 may include a barrier (not shown) disposed between the first portion 110 and the second portion 120. The barrier can reduce the movement of harmful gases generated in the first portion 110 to the second portion 120 or the third portion 130. For example, the barrier may be formed of a metallic material. Therefore, the user can inhale only the desired components in aerosol form.

[0069] In this embodiment, the fragrance element can be configured separately from one end of the aerosol generating article 100. Specifically, the fragrance element can be configured separately from the other end of the first portion 110, which is adjacent to the second portion 120. When the fragrance element is located in an area spaced apart from the other end of the first portion 110, it prevents the fragrance element from producing fragrance due to direct heating by an external heat source such as a lighter or match. The fragrance element may not be directly heated by an external heat source, but can produce fragrance by heat transferred from a combustible heat source. However, when directly heated by an external heat source, the fragrance element may receive heat from the external heat source and produce fragrance before the combustible heat source is ignited and burns. Since the fragrance produced by the user inhaling it may stop the ignition process before the combustible heat source is ignited, it may result in incomplete ignition.

[0070] For example, the first portion 110 may have a length of about 8 mm to about 13 mm, and the fragrance element may be located in a region about 2 mm to about 3 mm away from the other end of the first portion 110 opposite to one end of the first portion 110, wherein one end of the first portion 110 is adjacent to the second portion 120.

[0071] In one embodiment, the combustible heat source may include: a first region surrounded by a first wrapping paper 140; and a second region protruding outward from the first region and configured with a fragrance element. Specifically, the second region may protrude outward from the first region along the length direction of the aerosol generating article 100 and may not be surrounded by the first wrapping paper 140.

[0072] The ignition of the combustible heat source mainly occurs in the second zone, and the time at which the user can identify whether the combustible heat source has been ignited can vary depending on the location of the fragrance element.

[0073] The fragrance element can be located in a second area of ​​the combustible heat source that is not surrounded by the first packaging paper 140. When the combustible heat source in the second area is ignited, the fragrance element, located in the ignited portion of the combustible heat source, can produce fragrance simultaneously with the ignition of the heat source. Therefore, the user can recognize the fact that the combustible heat source is ignited at the same time as the heat source is lit.

[0074] For example, the first portion 110 has a length of about 8 mm to about 13 mm, and the first wrapping paper 140 may surround at least a portion of the first portion 110. The length of the first region surrounded by the first wrapping paper 140 may be about 3 mm to about 5 mm, and the length of the second region that is not surrounded by the first wrapping paper 140 and protrudes outward may be about 5 mm to about 8 mm.

[0075] However, the fragrance element can be located in a first area of ​​the combustible heat source surrounded by the first packaging paper 140. When the second area of ​​the combustible heat source is ignited, since the fragrance element is located at a position separated from the ignited portion of the combustible heat source, the heat generated by the combustion of the combustible heat source can be transferred to the fragrance element after a certain period of time. Therefore, the fragrance element produces fragrance after a certain period of time from the initial ignition point of the combustible heat source, and the user can recognize the fact that the combustible heat source has been ignited after a certain period of time from the initial ignition point of the combustible heat source.

[0076] The fragrance element included in the combustible heat source can be capsule-shaped, sheet-shaped, or elongated. Hereinafter, with reference to Figures 2 to 4, the shape of the fragrance element and the position of the fragrance element inside the aerosol generating article 100 will be described in more detail.

[0077] Figure 2a This is a diagram illustrating the structure of an aerosol-generating article comprising a capsule-shaped fragrance element according to an embodiment.

[0078] Reference Figure 2aThe flavoring element is a first capsule 210, which can be disposed inside a combustible heat source. The flavoring substance can be surrounded by the membrane of the first capsule 210 and included in the combustible heat source. For example, the membrane of the first capsule 210 can be prepared from gums such as agar, pectin, sodium alginate, carrageenan, gelatin, or guar gum. Additionally, a curing aid can be used as a material for forming the membrane of the first capsule 210. Here, for example, calcium chloride can be used as a gelling aid. Furthermore, a plasticizer can be used as a material for forming the membrane of the first capsule 210. Here, glycerol and / or sorbitol can be used as plasticizers. Additionally, a colorant can be used as a material for forming the membrane of the first capsule 210.

[0079] In one embodiment, the first capsule 210 may be located in a region spaced approximately 2 mm to approximately 8 mm from the other end of the first portion 110, which is opposite to one end of the first portion 110, wherein one end of the first portion 110 is adjacent to the second portion 120. Because the first capsule 210 is located in a region spaced a certain distance from the other end of the first portion, direct heating by an external heat source prevents the fragrance element from being generated. Furthermore, since the fragrance element generates fragrance after the combustible heat source is fully ignited, it prevents the user from stopping the ignition process before full ignition.

[0080] Figure 2b This is a diagram illustrating the structure of an aerosol-generating article comprising a plurality of capsule-shaped flavoring elements according to an embodiment.

[0081] Reference Figure 2b The flavoring element can be a first capsule 210 and a second capsule 211. The flavoring substance can be surrounded by the membranes of the first capsule 210 and the second capsule 211 and contained in a combustible heat source. According to an embodiment, the number of capsules can be increased or decreased.

[0082] The second capsule 211 may be located in a region spaced apart from the first capsule 210 along the length of the aerosol-generating article. Additionally, the second capsule 211 may be located in a region adjacent to the second portion 120. Because the second capsule 211 is located in a region adjacent to the second portion 120, when a fragrance is generated by the fragrance element of the second capsule 211, the user can identify that the aerosol-generating article 100 is in a puffable state. In an embodiment, the first capsule 210 may be located in a region spaced approximately 2 mm to approximately 8 mm from the other end of the first portion 110 opposite to one end of the first portion 110, wherein one end of the first portion 110 is adjacent to the second portion 120, and the second capsule 211 may be located in a region spaced approximately 8 mm to approximately 13 mm from the other end of the first portion 110.

[0083] The flavoring substance surrounded by the first capsule 210 may be the same as or different from the flavoring substance surrounded by the second capsule 211. For example, the flavoring substance surrounded by the first capsule 210 may contain coffee, and the flavoring substance surrounded by the second capsule 211 may contain tobacco. When a user inhales the coffee aroma, it can be recognized that a flammable heat source has been ignited; when inhaling the tobacco aroma, it can be recognized that the aerosol generating article 100 is in a puffable state.

[0084] Figure 3 This is a diagram illustrating the structure of an aerosol-generating article comprising a sheet-like fragrance element according to an embodiment.

[0085] Reference Figure 3 The fragrance element is a sheet 220 and can surround at least a portion of the outer peripheral surface of the combustible heat source. The fragrance element can be manufactured by coating the film with a fragrance substance in a liquid state or by immersing the film in a liquid fragrance substance. The sheet 220 containing the fragrance substance can surround the combustible heat source and be contained within the combustible heat source.

[0086] In one embodiment, the sheet 220 may wrap around the combustible heat source in a band-like manner. Because the band-like sheet 220 surrounds the entire outer peripheral surface of the combustible heat source, a fragrance can be produced through the sheet 220 even if the user ignites any location around the combustible heat source. Therefore, the user does not need to heat only a specific location on the outer peripheral surface of the combustible heat source.

[0087] Additionally, the sheet 220 may be surrounded by at least one of the first wrapping paper 140 and the second wrapping paper 150. Since the first wrapping paper 140 or the second wrapping paper 150 surrounding the sheet 220 increases the adhesion between the sheet and the combustible heat source by bringing the sheet into close contact with the combustible heat source, the sheet 220 may not separate from the combustible heat source even if an external impact is applied to the aerosol generating article 100 or during the process of the combustible heat source being ignited and burning.

[0088] Figure 4a This is a diagram illustrating the structure of an aerosol-generating article including an elongated fragrance element according to one embodiment.

[0089] Reference Figure 4a The fragrance element is an elongated rod 230, which can be disposed in a combustible heat source coaxial with the length direction of the aerosol generating article 100. The fragrance element can be manufactured by coating the elongated rod in a liquid state with a fragrance substance or by immersing the elongated rod in a liquid fragrance substance. The elongated rod containing the fragrance substance can be contained within the combustible heat source by inserting it into a gap in the combustible heat source.

[0090] In one embodiment, the elongated rod 230 can be inserted into the center of a combustible heat source. The center of the combustible heat source may have a channel extending in the longitudinal direction of the aerosol generating article 100, allowing the elongated rod 230 to be inserted into the center of the combustible heat source. The elongated rod 230 may be configured to be coaxial with the aerosol generating article 100 in the longitudinal direction.

[0091] Furthermore, the length of the elongated rod 230 can be the same as the length of the combustible heat source. For example, the length of the elongated rod 230 can be approximately 8 to 13 mm. Since the elongated rod 230 allows for the presence of a fragrance element throughout the combustible heat source along the length of the aerosol-generating article 100, fragrance can be produced via the elongated rod 230 regardless of where the user ignites the combustible heat source. The user can recognize the fact that the combustible heat source is ignited at the same time. Therefore, the user does not need to heat only a specific location of the combustible heat source.

[0092] Figure 4b This is a diagram showing the structure of an article that also includes an aerosol-generating article according to an embodiment of a combustor.

[0093] Reference Figure 4b The first part 110 also includes a combustor 240, which can be configured adjacent to the fragrance element. The combustor 240 can be immersed in ethanol. For example, the combustor immersed in ethanol can be a filament, thread, paper, or wooden stick impregnated with ethanol. Alternatively, the combustor 240 can be a solid fuel or a wire. For example, the solid fuel can be a combustion aid such as solid methanol. For example, the wire can be magnesium strip. The combustor 240 may burn faster than a combustible heat source. When the combustible heat source is ignited, the combustor 240 is also ignited and generates heat. The generated heat is transferred to the fragrance element, and the fragrance element can generate fragrance using the heat transferred from the combustor 240. By using the combustor 240, which burns faster than a combustible heat source, the user can more quickly identify when the combustible heat source has been ignited compared to using only a combustible heat source.

[0094] In one embodiment, the burner 240 is configured adjacent to the elongated rod 230, and the burner 240 and the elongated rod 230 can be disposed within a combustible heat source coaxial with the aerosol generating article 100 in the length direction. When the combustible heat source is ignited, the burner 240 is also ignited, and the heat generated from the burner 240 is transferred to the adjacent fragrance element so that the fragrance element can produce fragrance.

[0095] A second aspect of the invention is a combustible heat source for aerosol-generating articles, the combustible heat source comprising a fragrance element.

[0096] The matters described above for the first aspect can be applied equally to the second aspect of the invention.

[0097] The descriptions of the above embodiments are merely exemplary, and those skilled in the art should understand that various modifications and equivalent embodiments can be made therefrom.
