[0050] Aerosol-generating materials are materials capable of generating aerosols when excited, for example, by heating, irradiation, or any other method. Aerosol-generating materials can be in the form of, for example, solids, liquids, or gels, and may or may not contain active substances and / or flavorings. In some embodiments, aerosol-generating materials can include "amorphous solids," which may also be referred to as "monolithic solids" (i.e., non-fibrous). In some embodiments, amorphous solids can be dry gels. Amorphous solids are solid materials capable of holding fluids, such as liquids, within them.
[0051] In embodiments of the present invention, the article comprises an aerosol-generating composition, the aerosol-generating composition comprising first and second amorphous solid materials and / or an aerosol-generating material such as tobacco material.
[0052] Exemplary compositions of amorphous solids are described below. It is advantageous that the inventors have found that excellent aerosols can be produced from articles containing a first amorphous solid material and a second amorphous solid material. The compositions and material properties of each of the first and second amorphous solid materials can be selected to result in an improved aerosol when both are included in an article. Preferably, the first amorphous solid material can be selected to result in an improvement to a first aspect of the aerosol, the second amorphous solid material can be selected to result in an improvement to a second aspect of the aerosol, and a combination of the first and second amorphous solid materials can be selected to benefit from the improvements in both aspects.

[0061] In some further embodiments, the amorphous solid is Approximately 40-80% by weight of an amorphous solid aerosol-forming material, A gelling agent and an optional filler (i.e., in some examples the filler is present in the amorphous solid, and in other examples the filler is not present in the amorphous solid), wherein the combined amount of the gelling agent and filler is approximately 10-60% by weight of the amorphous solid (i.e., the gelling agent and filler together account for approximately 10-60% by weight of the amorphous solid), and Optionally, the product may contain an active substance and / or flavoring in an amount of up to approximately 20% by weight of amorphous solid (i.e., an active substance containing 20% by weight or less of amorphous solid).
[0062] The first amorphous solid is, 1-60% by weight of gelling agent, 0.1 to 50% by weight of an aerosol-forming agent, It may contain 0.1 to 80% by weight of fragrance. These weights are calculated based on dry weight, and the second amorphous solid is, Approximately 40-80% by weight of an amorphous solid aerosol-forming material, A gelling agent and an optional filler (i.e., in some examples the filler is present in the amorphous solid, and in other examples the filler is not present in the amorphous solid), wherein the combined amount of the gelling agent and filler is approximately 10-60% by weight of the amorphous solid (i.e., the gelling agent and filler together account for approximately 10-60% by weight of the amorphous solid), and Preferably, the mixture may optionally contain an active substance and / or flavoring in an amount of up to approximately 20% by weight of amorphous solid (i.e., an active substance containing 20% by weight or less of amorphous solid).
[0063] Alternatively, the first amorphous solid is, 1-50% by weight of gelling agent, 0.1 to 50% by weight of an aerosol-forming agent, It can contain 30-60% by weight of fragrance. These weights are calculated based on dry weight, and the second amorphous solid is, Approximately 40-80% by weight of an amorphous solid aerosol-forming material, A gelling agent and an optional filler (i.e., in some examples the filler is present in the amorphous solid, and in other examples the filler is not present in the amorphous solid), wherein the combined amount of the gelling agent and filler is approximately 10-60% by weight of the amorphous solid (i.e., the gelling agent and filler together account for approximately 10-60% by weight of the amorphous solid), and Optionally, the product may contain an amount of active substance and / or flavoring in an amount of up to approximately 20% by weight of amorphous solid (i.e., amorphous solid containing 20% by weight or less of active substance).
[0064] Alternatively, the first amorphous solid and the second amorphous solid may have the same composition. In some embodiments, the first amorphous solid and the second amorphous solid may have the same composition but differ in thickness or density.
[0065] The amorphous solid material is formed from a dried gel. The inventors have found that using the proportions of these components means that once the gel hardens, the fragrance compounds stabilize within the gel matrix, allowing for greater fragrance addition than in non-gel compositions. The added fragrance (e.g., menthol) is stable at high concentrations, and the product has a good shelf life.
[0066] In some cases, the amorphous solid can have a thickness of about 0.015 mm to about 1.5 mm. Preferably, the thickness can be in the range of about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm, 0.3 mm, or 1 mm. The inventors have found that in some embodiments, a material having a thickness of 0.2 mm is particularly preferred. The amorphous solid may consist of two or more layers, and the thickness described herein refers to the total thickness of those layers.
[0067] The inventors have established that if the amorphous solid forming the aerosol is too thick, the heating efficiency is impaired. This negatively impacts power consumption during use. Conversely, if the amorphous solid forming the aerosol is too thin, it becomes difficult to manufacture and handle. Very thin materials are more difficult to cast, may be brittle, and impair aerosol formation during use.
[0068] Considering these conflicting issues, the inventors have established that the material properties are optimized by the thickness of the amorphous solid as specified herein.
[0069] The thicknesses specified herein are average thicknesses of the material. In some cases, the thickness of amorphous solids may vary by as little as 25%, 20%, 15%, 10%, 5%, or 1%.
[0070] The amorphous solid may preferably contain about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, 25 wt%, 30 wt%, or 35 wt% to about 60 wt%, 55 wt%, 50 wt%, 45 wt%, 40 wt%, or 35 wt% of a gelling agent (all calculated based on dry weight). For example, the amorphous solid may contain 1-60%, 5-60 wt%, 20-60%, 25-55 wt%, 30-50 wt%, 35-45 wt%, 5-45 wt%, 10-40 wt%, or 20-35 wt% of a gelling agent.
[0071] In some embodiments, the gelling agent comprises a hydrophilic colloid. In some embodiments, the gelling agent comprises one or more compounds selected from the group comprising alginic acid, pectin, starch (and derivatives), cellulose (and derivatives), gum, silica or silicone compounds, clay, polyvinyl alcohol, and combinations thereof.

In some embodiments, the weight ratio of the cellulose-based gelling agent to the non-cellulose-based gelling agent is 1:4 to 4:1, 2:3 to 7:3, 2:3 to 3:2, or 1:1 to 3:2. In some embodiments, the weight ratio of the cellulose-based gelling agent to the non-cellulose-based gelling agent is greater than 1:1. That is, in some embodiments, the cellulose-based gelling agent is present in a larger amount than the non-cellulose-based gelling agent. In some embodiments, the weight ratio of the cellulose-based gelling agent to the non-cellulose-based gelling agent is approximately 1:1.
[0075] While we do not wish to be constrained by theory, it is believed that including one or more cellulosic gelling agents in an amorphous solid stabilizes flavoring compounds (e.g., menthol) within the matrix, allowing for controlled release of flavoring during a smoking session. The flavoring (e.g., menthol) remains stable at high concentrations, and the product has a good shelf life.
[0076] In some embodiments, the amorphous solid may contain a gelling agent comprising carrageenan.
[0077] In some examples, the gelling agent contains alginic acid in an amount of approximately 5–40% by weight or 15–40% by weight of the amorphous solid. That is, the amorphous solid contains alginic acid in an amount of approximately 5–40% by weight or 15–40% by weight of the amorphous solid by dry weight. In some examples, the amorphous solid contains alginic acid in an amount of approximately 20–40% by weight or approximately 15–35% by weight of the amorphous solid.
[0078] In some examples, the gelling agent contains approximately 3–15% by weight of pectin relative to the amorphous solid. That is, the amorphous solid contains approximately 3–15% by weight of pectin relative to the dry weight of the amorphous solid. In some examples, the amorphous solid contains approximately 5–10% by weight of pectin relative to the amorphous solid.
[0079] In some examples, the gelling agent contains approximately 3–40% by weight of guar gum relative to the amorphous solid. That is, the amorphous solid contains approximately 3–40% by weight of guar gum relative to the dry weight of the amorphous solid. In some examples, the amorphous solid contains approximately 5–10% by weight of guar gum relative to the amorphous solid. In some examples, the amorphous solid contains approximately 15–40% by weight, or approximately 20–40% by weight, or approximately 15–35% by weight of guar gum relative to the amorphous solid.
[0080] In some examples, alginate is present in an amount of at least about 50% by weight of the gelling agent. In some examples, the amorphous solid contains alginate and pectin, and the ratio of alginate to pectin is 1:1 to 10:1. The ratio of alginate to pectin is typically greater than 1:1, meaning that alginate is present in a larger amount than pectin. In some examples, the ratio of alginate to pectin is about 2:1 to 8:1, or about 3:1 to 6:1, or about 4:1.
[0081] Amorphous solids may contain fillers. Typically, an amorphous solid contains gelling agents and fillers (if present) in an amount of about 10–60% by weight of the amorphous solid. In an example, the amorphous solid contains 1–15% by weight of the amorphous solid, e.g., 5–15% by weight, or 8–12% by weight of the amorphous solid, as fillers. In an example, the amorphous solid contains more than 1% by weight, 5% by weight, or 8% by weight of the amorphous solid, as fillers. In an example, the amorphous solid contains less than 40% by weight, 30% by weight, 20% by weight, 15% by weight, 12% by weight, 10% by weight, 5% by weight, or 1% by weight of the amorphous solid, as fillers. In other examples, the amorphous solid does not contain fillers.
[0082] In the example, the amorphous solid contains gelling agents and fillers in amounts of approximately 10% by weight, 20% by weight, 25% by weight, 30% by weight, or 35% to approximately 60% by weight, 55% by weight, 50% by weight, or 45% by weight of the amorphous solid. In the example, the amorphous solid contains gelling agents and fillers in amounts of approximately 20-60% by weight, 25-55% by weight, 30-50% by weight, or 35-45% by weight of the amorphous solid.
[0083] The filler, if present, may include one or more inorganic fillers such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents, such as molecular sieves. The filler may also include one or more organic fillers such as wood pulp, cellulose, and cellulose derivatives. In certain cases, the amorphous solid does not contain calcium carbonate, such as chalk.
[0084] In some examples involving fillers, the filler can be fibrous. For example, the filler can be a fibrous organic filler material such as wood pulp, hemp fiber, cellulose, or a cellulose derivative. While we do not wish to be constrained by theory, it is thought that including a fibrous filler in an amorphous solid can increase the tensile strength of the material. This may be particularly advantageous in examples where the amorphous solid is provided as a sheet, such as when the amorphous solid sheet is circumscribed around a material rod.
[0085] In some embodiments, the amorphous solid contains less than 60% by weight of filler, for example, 1% to 60% by weight, or 5% to 50% by weight, or 5% to 30% by weight, or 10% to 20% by weight.
[0086] In other embodiments, the amorphous solid contains less than 20% by weight, preferably less than 10% by weight, or less than 5% by weight of filler. In some cases, the amorphous solid contains less than 1% by weight of filler, and in some cases, it contains no filler.
[0087] The amorphous solid may contain about 1% by weight, 3% by weight, or 5% to about 7% by weight, 10% by weight, 12% by weight, or 15% by weight of an emulsifier (all calculated on a dry weight basis). In exemplary embodiments, the amorphous solid may contain about 3% by weight, 4% by weight, or 5% to about 7% by weight, 8% by weight, or 10% by weight of an emulsifier. For example, the amorphous solid may contain 4 to 8% by weight or 5 to 7% by weight of an emulsifier.
[0088] In some cases, the emulsifier comprises one or more compounds selected from agar, xanthan gum, gum arabic (acacia gum), guar gum, locust bean gum, pectin, carrageenan, and lecithin. In some cases, the emulsifier comprises guar gum, consists essentially of guar gum, or is composed of guar gum.
[0089] In the example, the amorphous solid does not contain tobacco fibers. In a specific example, the amorphous solid does not contain fibrous material.
[0090] In some embodiments, the aerosol-generating composition does not contain tobacco fibers. In certain embodiments, the aerosol-generating composition does not contain fibrous materials.
[0091] In some embodiments, the aerosol product does not contain tobacco fibers. In certain embodiments, the aerosol product does not contain fibrous materials.
[0092] The amorphous solid may preferably contain about 0.1% by weight, 0.5% by weight, 1% by weight, 3% by weight, 5% by weight, 7% by weight, or 10% to about 80% by weight, 50% by weight, 45% by weight, 40% by weight, 35% by weight, 30% by weight, or 25% by weight of aerosol-forming material (all calculated on a dry weight basis). For example, the amorphous solid may contain about 40-80% by weight, 40-75% by weight, 50-70% by weight, or 55-65% by weight of aerosol-forming material. The aerosol-forming material can act as a plasticizer. For example, the amorphous solid may contain 0.5-40% by weight, 3-35% by weight, or 10-25% by weight of aerosol-forming material. In some cases, the aerosol-forming material comprises one or more compounds selected from erythritol, propylene glycol, glycerol, triacetin, sorbitol, and xylitol. In some cases, the aerosol-forming material contains glycerol, is essentially composed of glycerol, or is composed of glycerol. The inventors have established that if the plasticizer content is too high, the amorphous solid may absorb water, and the resulting material may not create a suitable consumption experience during use. The inventors have established that if the plasticizer content is too low, the amorphous solid may become brittle and easily break. The inventors have found it advantageous that an article containing a suitable amount of aerosol-forming material may comprise a first amorphous solid material containing a first amount of aerosol-forming material and a second amorphous solid material containing a second amount of aerosol-forming material. The first amount of aerosol-forming material may be greater than the second amount of aerosol-forming material. The inventors have found it advantageous that such a configuration makes it possible to provide a higher level of aerosol-forming material within the amorphous solid component of the article without resulting in the aforementioned drawbacks associated with high plasticizer content.
[0093] The plasticizer content specified herein provides the amorphous solid with flexibility that allows the sheet to be wound onto a bobbin, which is useful in the production of aerosol products.
[0094] The amorphous solid may contain fragrances. Preferably, the amorphous solid may contain up to approximately 80% by weight, 70% by weight, 60% by weight, 55% by weight, 50% by weight, or 45% by weight of fragrance.
[0095] In some cases, amorphous solids may contain at least about 0.1% by weight, 1% by weight, 10% by weight, 20% by weight, 30% by weight, 35% by weight, or 40% by weight of flavoring (all calculated on a dry weight basis). For example, amorphous solids may contain 1–80% by weight, 10–80% by weight, 20–70% by weight, 30–60% by weight, 35–55% by weight, or 30–45% by weight of flavoring. In some cases, the flavoring may contain menthol, consist essentially of menthol, or consist of menthol.
[0096] In some cases, amorphous solids may further contain emulsifiers to emulsify molten flavorings during manufacturing. For example, amorphous solids may contain about 5% to about 15% by weight, preferably about 10% by weight, of emulsifiers (calculated based on dry weight). The emulsifier may include acacia gum.
[0097] In some cases, amorphous solids do not contain flavorings, and in certain cases, amorphous solids do not contain active ingredients.
[0098] In some embodiments, the amorphous solid is a hydrogel containing less than about 20% by weight of water, calculated based on wet weight. In some cases, the hydrogel may contain less than about 15% by weight, 12% by weight, or 10% by weight of water, calculated based on wet weight. In some cases, the hydrogel may contain at least about 1% by weight, 2% by weight, or at least about 5% by weight of water (WWB).
[0099] In some embodiments, the amorphous solid further comprises an active substance. For example, in some cases, the amorphous solid further comprises tobacco material and / or nicotine. In some cases, the amorphous solid may contain 5 to 60% by weight (calculated on a dry weight basis) of tobacco material and / or nicotine. In some cases, the amorphous solid may contain about 1% by weight, 5% by weight, 10% by weight, 15% by weight, 20% by weight, or 25% by weight to about 70% by weight, 60% by weight, 50% by weight, 45% by weight, 40% by weight, 35% by weight, 30% by weight, 20% by weight, 15% by weight, or 10% by weight (calculated on a dry weight basis) of the active substance. In some cases, amorphous solids can contain approximately 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to approximately 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (calculated based on dry weight) of tobacco material. For example, amorphous solids can contain 10-50 wt%, 15-40 wt%, or 20-35 wt% of tobacco material. In some cases, amorphous solids can contain approximately 1 wt%, 2 wt%, 3 wt%, or 4 wt% to approximately 20 wt%, 18 wt%, 15 wt%, or 12 wt% (calculated based on dry weight) of nicotine. For example, amorphous solids can contain 1-20 wt%, 2-18 wt%, or 3-12 wt% of nicotine.
[0100] In some cases, amorphous solids contain active substances such as tobacco extract. In some cases, amorphous solids may contain 5–60% by weight (calculated on a dry weight basis) of tobacco extract. In some cases, amorphous solids may contain tobacco extract in amounts of approximately 5% by weight, 10% by weight, 15% by weight, 20% by weight, or 25% by weight to approximately 60% by weight, 50% by weight, 45% by weight, 40% by weight, 35% by weight, or 30% by weight (calculated on a dry weight basis). For example, amorphous solids may contain 10–50% by weight, 15–40% by weight, or 20–35% by weight of tobacco extract. The tobacco extract may contain nicotine in concentrations such that the amorphous solid contains 1% by weight, 1.5% by weight, 2% by weight, or 2.5% by weight to approximately 6% by weight, 5% by weight, 4.5% by weight, or 4% by weight (calculated on a dry weight basis).
[0101] In some cases, nicotine other than that derived from tobacco extract may not be present in the amorphous solid.
[0102] In some embodiments, the amorphous solid does not contain tobacco material but contains nicotine. In some such cases, the amorphous solid can contain about 1% by weight, 2% by weight, 3% by weight, or 4% by weight to about 20% by weight, 18% by weight, 15% by weight, or 12% by weight (calculated based on dry weight) of nicotine. For example, the amorphous solid can contain 1 to 20% by weight, 2 to 18% by weight, or 3 to 12% by weight of nicotine.
[0103] In some cases, the total content of active substances and / or fragrances may be at least about 0.1% by weight, 1% by weight, 5% by weight, 10% by weight, 20% by weight, 25% by weight, or 30% by weight. In some cases, the total content of active substances and / or fragrances may be less than about 90% by weight, 80% by weight, 70% by weight, 60% by weight, 50% by weight, or 40% by weight (all calculated on a dry weight basis).
[0104] In some cases, the total content of tobacco material, nicotine, and flavorings may be at least about 0.1% by weight, 1% by weight, 5% by weight, 10% by weight, 20% by weight, 25% by weight, or 30% by weight. In some cases, the total content of active substances and / or flavorings may be less than about 90% by weight, 80% by weight, 70% by weight, 60% by weight, 50% by weight, or 40% by weight (all calculated on a dry weight basis).
[0105] Amorphous solids can be made from gels, which may further contain solvents, typically in amounts of 0.1 to 50% by weight. However, the inventors have established that the inclusion of a solvent in which the fragrance can dissolve can reduce the stability of the gel, potentially causing the fragrance to crystallize from the gel. Therefore, in some cases, the gel does not contain a solvent in which the fragrance can dissolve.
[0106] In some examples, amorphous solids in sheet form can have tensile strengths of about 150 N / m to about 3000 N / m, for example, 150 N / m to 2500 N / m, or 150 N / m to 2000 N / m, or 200 N / m to 1700 N / m, or 250 N / m to 1500 N / m. In some examples, such as when the amorphous solid does not contain fillers, the amorphous solid can have tensile strengths of 150 N / m to 500 N / m, or 200 N / m to 300 N / m, or about 250 N / m. Such tensile strengths may be particularly suitable for embodiments in which the amorphous solid material is formed as a sheet and then shredded and incorporated into an aerosol product.
[0107] In some examples, such as those in which the amorphous solid contains a filler, the amorphous solid can have a tensile strength of 150 N / m to 3000 N / m, for example, 500 N / m to 1200 N / m, or 700 N / m to 900 N / m, or about 800 N / m or more. In some examples, the amorphous solid can have a tensile strength greater than 500 N / m, greater than 1000 N / m, or greater than 1500 N / m. Such tensile strengths may be particularly suitable for embodiments in which the amorphous solid material is included in aerosol products / assemblies, preferably in the form of rolled sheets or tubes.
[0108] In some cases, amorphous solids may consist essentially of a gelling agent, water, aerosol-forming material, fragrance, and optionally an active substance, or these materials. In some cases, the amorphous solid may consist essentially of a gelling agent, water, aerosol-forming material, flavoring, and optionally tobacco material and / or a nicotine source, or may consist of these materials.
[0109] In some embodiments, the amorphous solid is formed as a sheet.
[0110] In the embodiments described herein, amorphous solid materials can be incorporated into articles in the form of sheets. Amorphous solid sheets can be incorporated as planar sheets, as bundled or assembled sheets, as compressed sheets, or as rolled sheets (i.e., in the form of tubes). In some such cases, the amorphous solids of these embodiments can be included in aerosol products as sheets, for example, as sheets circumscribing a rod of an aerosolizable material (e.g., cigarettes). For example, an amorphous solid sheet can be formed on a roll of paper circumscribing an aerosolizable material such as cigarettes. Additionally or alternatively, amorphous solid materials in the form of sheets can be shredded and then incorporated into articles, preferably mixed with an aerosolizable material such as cigarette material.
[0111] The amorphous solid in sheet form weighs approximately 30 g / m².2 ~ about 150 g / m 2 and can have any suitable basis weight, such as. In some cases, the sheet is about 55 g / m 2 ~ about 135 g / m 2 or about 55 g / m 2 ~ about 120 g / m 2 and can have a mass per unit area. In some examples, when an amorphous solid is shredded and mixed with a tobacco material, the amorphous solid is about 80 - about 120 g / m 2 or about 70 - about 110 g / m 2 or about 90 - about 110 g / m 2 and can have a mass per unit area. These ranges can provide a density similar to that of cut - rag tobacco, and as a result, can provide a mixture of these materials that does not easily separate. Such basis weights can be particularly suitable when the amorphous solid material is included as a shredded sheet in an aerosol - generating article. In some cases, the sheet is about 30 - 70 g / m 2 40 - 60 g / m 2 or 25 - 60 g / m 2 and can have a mass per unit area. In some examples, the amorphous solid is about 60 g / m 2 ~ about 90 g / m 2 and preferably can have a basis weight, for example, of about 68 gsm or about 83 gsm.
[0112] The amorphous solid can be present on or within a support to form a substrate. The support functions as a support on which the amorphous solid layer is formed and facilitates manufacturing. The support can provide rigidity to the amorphous solid layer and can facilitate handling.
[0113] The support can be any suitable material that can be used to support an amorphous solid. In some cases, the support can be formed from a material selected from metal foil, e.g., aluminum foil, paper, carbon paper, greaseproof paper, ceramics, carbon allotropes, e.g., graphite and graphene, plastics, cardboard, wood, or combinations thereof. In some cases, the support can include tobacco material, e.g., a sheet of recycled tobacco, or consist of such material. In some cases, the support can be formed from a material selected from metal foil, paper, cardboard, wood, or combinations thereof. In some cases, the support includes paper. In some cases, the support itself can be a laminated structure comprising layers of material selected from the aforementioned list. In some cases, the support can also function as a flavoring support. For example, the support can be impregnated with a flavoring or tobacco extract.
[0114] In some cases, the support can be magnetic. This property can be used to fasten the support to an assembly in use, or to generate a specific amorphous solid shape. In some cases, the aerosol-generating composition may have one or more magnets, and one or more magnets can be used to fasten the material to an induction heater in use.
[0115] The thickness of the support layer is preferably in the range of approximately 10 μm, 15 μm, 17 μm, 20 μm, 23 μm, 25 μm, 50 μm, 75 μm, or 0.1 mm to approximately 2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm, or 0.5 mm. The support may include two or more layers, and the thickness described herein refers to the total thickness of those layers. In some cases, the support can be substantially or entirely impermeable to gases and / or aerosols. This prevents aerosols or gases from passing through the support layer, thereby controlling the flow and ensuring that the aerosols or gases are delivered to the user. This can also be used to prevent condensation or other deposition of gases / aerosols during use on the surface of heaters, for example, located within an aerosol generation assembly. Thus, in some cases, consumption efficiency and hygiene can be improved.
[0116] In some cases, the surface of the support in contact with the amorphous solid can be porous. For example, in one case, the support is made of paper. The inventors have found that porous supports, such as paper, are particularly suitable for the present invention, as the porous layer (e.g., paper) in contact with the amorphous solid layer forms a strong bond. The amorphous solid is formed by drying a gel, and is not limited by theory, but it is thought that the support is partially bonded to the gel when the slurry in which the gel is formed partially permeates the porous support (e.g., paper), and so the gel hardens and forms crosslinks. This provides a strong bond between the gel and the support (and between the dried gel and the carrier).
[0117] In addition, surface roughness can contribute to the bonding strength between the amorphous material and the support. The inventors have found that the roughness of the paper (the surface in contact with the support) is preferably in the range of 50 to 1000 Beck seconds, preferably 50 to 150 Beck seconds, and preferably 100 Beck seconds (measured over an air pressure interval of 50.66 to 48.00 kPa) (a Beck smoothness tester is an instrument used to determine the smoothness of the surface of paper, where air at a specified pressure leaks between a smooth glass surface and a paper sample, and the time (in seconds) it takes for a fixed volume of air to leak between these surfaces is called "Beck smoothness").
[0118] Conversely, the surface of the support facing away from the amorphous solid can be positioned to contact the heater, and a smoother surface can provide more efficient heat transfer. Therefore, in some cases, the support is positioned to have a rougher surface in contact with the amorphous material and a smoother surface facing away from the amorphous material.
[0119] In one particular case, the support can be a foil backed with paper, where this paper layer is in contact with the amorphous solid layer, and the properties discussed in the preceding paragraph are given by this contact. The foil backing is substantially impermeable and provides control over the aerosol channel. Metal foil backing can also serve to conduct heat to the amorphous solid.
[0120] In another case, the foil layer of a paper-backed foil comes into contact with an amorphous solid. This foil is substantially impermeable, thereby preventing water supplied to the amorphous solid from being absorbed by the paper. If water is absorbed by the paper, its structural integrity may be weakened.
[0121] In some cases, the support is formed from or includes a metal foil, such as aluminum foil. A metallic support can allow for better conduction of thermal energy to an amorphous solid. Additionally or alternatively, the metal foil can function as a susceptor in an induction heating system. In certain embodiments, the support includes a metal foil layer and a support layer, such as cardboard. In these embodiments, the metal foil layer may have a thickness of less than 20 μm, for example, about 1 μm to about 10 μm, preferably about 5 μm.
[0122] In some cases, the support can have a thickness of about 0.010 mm to about 2.0 mm, preferably about 0.015 mm, 0.02 mm, 0.05 mm, or 0.1 mm to about 1.5 mm, 1.0 mm, or 0.5 mm.
[0123] In the example, the aerosol-generating composition includes an aerosol-generating material. In the example, the aerosol-generating material includes an amorphous solid material and a tobacco material. The amorphous solid can be provided as shredded sheets and optionally mixed with the tobacco material (e.g., loose tobacco). Alternatively or additionally, the amorphous solid can be provided in the form of a sheet, such as a sheet circumscribing the aerosol-generating material rod.
[0124] In the example, an article having a substantially cylindrical shape is provided, comprising an aerosol-generating composition, the aerosol-generating composition comprising an amorphous solid as a shredded sheet mixed with tobacco material.
[0125] Alternatively or additionally, the aerosol-generating composition may include an amorphous solid as a sheet, such as a sheet that is in contact with the tobacco material rod.
[0126] In some examples, the article comprises a portion containing a first amorphous solid material as a shredded sheet mixed with tobacco material, and a second amorphous solid material as a sheet circumscribing the portion.
[0127] In another example, the aerosol-generating composition comprises a portion containing tobacco material and first and second amorphous solid materials, each of which is provided as a sheet circumscribing the portion containing tobacco material.
[0128] In this specification, the term “tobacco material” refers to any material including tobacco or its derivatives or substitutes. The term “tobacco material” may include one or more of tobacco, tobacco derivatives, puffed tobacco, remanufactured tobacco, or tobacco substitutes. Tobacco material may include one or more of ground tobacco, tobacco fibers, shredded tobacco, extruded tobacco, tobacco stalks, tobacco leaves, remanufactured tobacco, and / or tobacco extracts.
[0129] In the tobacco materials described herein, the tobacco material may contain filler components. Filler components are generally non-tobacco components, i.e., components that do not contain tobacco-derived raw materials. Filler components may be non-tobacco fibers such as wood fibers, pulp, or wheat fibers, or other cellulosic substances. Filler components may also be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may also be non-tobacco cast materials or non-tobacco extruded materials. Filler components may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the composition. In some embodiments, filler components are absent.
[0130] In the tobacco materials described herein, the tobacco material contains an aerosol-forming material.
[0131] In some embodiments, the aerosol-forming material of the tobacco material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10-20% by weight of the tobacco material, for example, 13-16% by weight of the composition, or about 14% or 15% by weight of the composition. If present, propylene glycol may be present in an amount of 0.1-0.3% by weight of the composition.
[0132] Aerosol-forming materials may be included in any component of the tobacco material, for example, any tobacco component and / or filler component, if present. Alternatively or additionally, aerosol-forming materials may be added separately to the tobacco material. In either case, the total amount of aerosol-forming materials in the tobacco material may be as defined herein.
[0133] The tobacco material can contain 10% to 90% by weight of tobacco leaves, and the aerosol-forming material is supplied in an amount of up to approximately 10% by weight of tobacco leaves. To achieve an overall level of 10% to 20% by weight of aerosol-forming material in the tobacco material, it has been found to be advantageous that this can be added in a larger weight percentage than other components of the tobacco material, such as recycled tobacco material.
[0134] The tobacco materials described herein contain nicotine. The nicotine content is 0.5 to 1.75% by weight of the tobacco material, and can be, for example, 0.8 to 1.5% by weight of the tobacco material. In addition or by alternative means, the tobacco material contains 10% to 90% by weight of tobacco leaves and has a nicotine content greater than 1.5% by weight of the tobacco leaves. It has been found to be advantageous that by using tobacco leaves with a nicotine content greater than 1.5% in combination with a lower nicotine base material such as recycled cigarettes, it is possible to provide a tobacco material that has an appropriate nicotine level while having better perceptual performance than when recycled cigarettes are used alone. Tobacco leaves, for example, shredded rag tobacco, can have a nicotine content of, for example, 1.5% to 5% by weight of the tobacco leaves.
[0135] The tobacco materials described herein may contain aerosol modifiers such as any of the flavorings described herein. In one embodiment, the tobacco material contains menthol to form a menthol-containing article. The tobacco material may contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, more preferably 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol. The tobacco material may contain 2% to 8% by weight of menthol, preferably 3% to 7% by weight of menthol, more preferably 4% to 5.5% by weight of menthol. In one embodiment, the tobacco material contains 4.7% by weight of menthol. Such high levels of menthol loading can be achieved by using a high proportion, for example, more than 50% by weight of recycled tobacco material. Alternatively or additionally, the level of menthol loading that can be achieved can be increased by using a large amount of aerosol-generating material, for example, tobacco material, for example about 500 mm 3 More, or preferably about 1000 mm 3 More aerosol-generating materials, such as tobacco materials, are used.
[0136] In the compositions described herein, when an amount is given in weight percent, to avoid misunderstanding, this refers to dry basis weight unless otherwise specifically indicated. Therefore, for the purpose of determining weight percent, any water that may be present in the tobacco material or any of its components is completely disregarded. The moisture content of the tobacco material described herein may vary, for example, from 5 to 15% by weight. The moisture content of the tobacco material described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The moisture content can be determined by Karl Fischer analysis, as is known to those skilled in the art. On the other hand, to avoid misunderstanding, even when the aerosol-forming material is a liquid-phase component such as glycerol or propylene glycol, all components other than water are included in the weight of the tobacco material. However, when the aerosol-forming material is provided within the tobacco component of the tobacco material or the filler component of the tobacco material (if present), instead of being added separately to the tobacco material, the aerosol-forming material is not included in the weight of the tobacco component or filler component, but rather in the weight of the “aerosol-forming material” in the weight percent defined herein. All other ingredients present in the tobacco component are included in the weight of the tobacco component, even if they originate from non-tobacco sources (for example, non-tobacco fibers in the case of recycled cigarettes).
[0137] In one embodiment, the tobacco material comprises tobacco components defined herein and an aerosol-forming material defined herein. In one embodiment, the tobacco material consists essentially of tobacco components defined herein and an aerosol-forming material defined herein. In one embodiment, the tobacco material consists of tobacco components defined herein and an aerosol-forming material defined herein.
[0138] Recycled tobacco can be present in the tobacco components of the tobacco material described herein in an amount of 10% to 100% by weight of the tobacco components. In embodiments, recycled tobacco is present in an amount of 10% to 80% or 20% to 70% by weight of the tobacco components. In further embodiments, the tobacco components consist essentially of recycled tobacco or consist of recycled tobacco. In preferred embodiments, leaf tobacco is present in the tobacco components of the tobacco material in an amount of at least 10% by weight of the tobacco components. For example, leaf tobacco may be present in an amount of at least 10% by weight of the tobacco components, and the remainder of the tobacco components may consist of recycled tobacco, band-cast recycled tobacco, or a combination of band-cast recycled tobacco and other forms of tobacco such as tobacco granules. Leaf tobacco may be present in an amount of up to 40% or 60% of the tobacco material, and it is preferable that the remainder of the tobacco components consist of recycled tobacco, band-cast recycled tobacco, or a combination of band-cast recycled tobacco and other forms of tobacco such as tobacco granules.
[0139] Recycled tobacco refers to tobacco material formed by a process in which tobacco raw materials are extracted with a solvent to yield an extract of residue containing soluble substances and fibrous materials. The extract (usually concentrated and optionally further processed) is then recombined with fibrous materials from the residue by depositing the extract onto fibrous materials (usually, after purification of the fibrous materials, optionally a portion of non-tobacco fibers is added). The recombination process is similar to the papermaking process.
[0140] Recycled cigarettes can be any type of recycled cigarette known in the art. In certain embodiments, recycled cigarettes are made from raw materials comprising one or more of tobacco strips, tobacco stalks, and whole tobacco leaves. In further embodiments, recycled cigarettes are made from raw materials comprising tobacco strips and / or whole tobacco leaves, as well as tobacco stalks. However, in other embodiments, fragments, granules, and husks may also be used as raw materials by alternative or additional means.
[0141] Recycled cigarettes for use in the tobacco materials described herein can be prepared by methods known to those skilled in the art for preparing recycled cigarettes.
[0142] In some cases, tobacco material can be included in an article / assembly in the form of a sheet. In some cases, tobacco material can be included as a flat sheet. In some cases, tobacco material can be included as a flat sheet, as a bundled or assembled sheet, as a crimped sheet, or as a rolled sheet (i.e., in the form of a tube). In some cases, tobacco material can be formed as a sheet and then shredded and incorporated into an article.
[0143] The assembly may comprise an integrated aerosol product and a heater, or a heating device into which an article is inserted during use.
[0144] In the example, the tobacco material includes an aerosol-forming material. Typically, the tobacco material includes finely shredded tobacco, and the aerosol-forming material is added to the tobacco fragments. In the example, the tobacco material contains about 1–10% by weight of the tobacco material, for example, 3–6% by weight of the aerosol-forming material.
[0145] In the example, the aerosol-generating composition contains about 5-30% by weight of aerosol-forming material, for example, 10-20% by weight or 13-18% by weight of the aerosol-generating composition. In the example, the aerosol-generating composition contains about 15% by weight of aerosol-forming material of the aerosol-generating composition. This amount includes any aerosol-forming material present in the aerosol-generating composition, such as aerosol-forming material provided in an amorphous solid and aerosol-forming material added to finely chopped tobacco.
[0146] One aspect of the present invention relates to an article for use with a non-flammable aerosol supply system. The article comprises an aerosol-generating composition as described herein. The consumable is an article, some or all of which is intended to be consumed by the user during use. The consumable may contain or consist of an aerosol-generating composition. The consumable may contain one or more other elements, such as a filter or an aerosol-modifying substance. The consumable may contain a heating element that releases heat during use to generate an aerosol in the aerosol-generating composition. The heating element may contain, for example, a flammable material or a susceptor that can be heated by penetration by a fluctuating magnetic field.
[0147] A susceptor is a material that can be heated by penetration of a fluctuating magnetic field, such as an alternating magnetic field. The heating material can be a conductive material, and therefore penetration of a conductive material by a fluctuating magnetic field causes inductive heating of the heating material. The heating material can be a magnetic material, and therefore penetration of a magnetic material by a fluctuating magnetic field causes magnetic hysteresis heating of the heating material. The heating material can be both conductive and magnetic, and therefore can be heated by either heating mechanism.
[0148] Induction heating is the process by which a conductive object is heated when a fluctuating magnetic field penetrates it. This process is described by Faraday's law of electromagnetic induction and Ohm's law. An induction heater may comprise an electromagnet and a device for passing a fluctuating current, such as an alternating current, through the electromagnet. When the electromagnet and the object to be heated are suitably positioned relative to each other so that the fluctuating magnetic field produced by the electromagnet penetrates the object, one or more eddy currents are generated within the object. The object has resistance to the flow of current. Therefore, when such eddy currents are generated within the object, the object is heated by the flow against its electrical resistance. This process is called Joule, Ohm, or resistance heating.
[0149] In this example, the susceptor is in a closed-circuit configuration. It has been found that when the susceptor is in a closed-circuit configuration, the magnetic coupling between the susceptor and the electromagnet during use is enhanced, resulting in greater or improved Joule heating.
[0150] Magnetic hysteresis heating is the process by which an object made of a magnetic material is heated when a fluctuating magnetic field penetrates the object. A magnetic material can be thought of as containing many atomic-scale magnets or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles align with the field. Therefore, when a fluctuating magnetic field, such as an alternating magnetic field produced by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes with the fluctuation of the applied magnetic field. This change in orientation of the magnetic dipoles generates heat within the magnetic material.
[0151] When an object possesses both conductivity and magnetism, a fluctuating magnetic field entering the object can cause both Joule heating and magnetic hysteresis heating. Furthermore, the magnetic field can be reinforced by using magnetic materials, thereby facilitating Joule heating.
[0152] In each of the above processes, heat is generated within the object itself rather than through an external heat source via heat conduction. Therefore, by selecting a particularly suitable material and geometry for the object, as well as a suitable magnitude and direction of the fluctuating magnetic field relative to the object, a rapid temperature rise and a more uniform heat distribution can be achieved in the object. Furthermore, since induction heating and magnetic hysteresis heating do not require a physical connection between the fluctuating magnetic field source and the object, they offer greater design freedom and control compared to heating profiles, and thus reduce costs. The articles of the present invention can be provided in any preferred shape. In some examples, the articles are provided as rods (for example, substantially cylindrical).
[0153] One aspect of the present invention provides a non-combustible aerosol supply system comprising the articles described herein and a non-combustible aerosol supply device equipped with a heater configured to heat the aerosol product non-combustibly. The non-combustible aerosol supply system may also be called an aerosol generation assembly. The non-combustible aerosol supply device may also be called an aerosol generation apparatus.
[0154] In some cases, during use, the heater can non-combustibly heat the aerosol-generating composition to a temperature of 350°C or less, for example, between 120°C and 350°C. In some cases, the heater can non-combustibly heat the aerosol-generating composition to a temperature of 140°C to 250°C or 220°C to 280°C during use.
[0155] The heater is configured to heat the aerosol product, and therefore the aerosol-generating composition, in a non-combustible manner. In some cases, the heater may be a thin-film electrical resistance heater. In other cases, the heater may include an induction heater, etc. The heater may be a combustion heat source or a chemical heat source that undergoes an exothermic reaction to the heat of the product during use. The aerosol-generating assembly may comprise multiple heaters. The heater(s) may be powered by batteries.
[0156] The aerosol product may further include a cooling element and / or a filter. The cooling element, if present, may act or function to cool the gas or aerosol component. In some cases, the cooling element may act to cool and condense the gas component to form an aerosol. The cooling element may also act to keep the very hot parts of the non-flammable aerosol supply device away from the user. The filter, if present, may include any suitable filter known in the art, such as a cellulose acetate plug.
[0157] In some cases, the aerosol generating assembly can be a non-combustion heating device. That is, the aerosol generating assembly may include a solid tobacco storage material (but not a liquid aerosol generating material). In some cases, the amorphous solid may include the tobacco material. Non-combustion heating devices are disclosed in whole in International Publication No. 2015 / 062983, which is incorporated by reference.
[0158] Aerosol products (which may also be referred to herein as articles, cartridges, or consumables) can be adapted for use in THPs, e-cigarette hybrid devices, or other aerosol generating devices. In some cases, articles may further include filters and / or cooling elements (as described above). In some cases, packaging materials such as paper may be attached to the aerosol products. In certain examples, articles are adapted for use with tobacco heating products.
[0159] The aerosol product may further include aeration apertures. These aeration apertures may be provided on the side walls of the article. In some cases, the aeration apertures may be provided on filters and / or cooling elements. These apertures may allow the air drawn into the article during use to be cooled, and this air may be mixed with heated volatile components to cool the aerosol.
[0160] Ventilation facilitates the generation of visible heat-volatile components from articles heated during use. These heat-volatile components become visible through a process of cooling them to the point where supersaturation occurs. The heat-volatile components then undergo droplet formation, also known as nucleation, and ultimately the size of the aerosol particles of the heat-volatile components increases due to further condensation of the heat-volatile components and the solidification of newly formed droplets from the heat-volatile components.
[0161] In some cases, the ratio of cooling air to the sum of heated volatile components and cooling air, known as the permeability ratio, is at least 15%. A 15% permeability ratio makes the heated volatile components visible by the method described above. The visibility of the heated volatile components allows the user to identify that volatile components have been generated, improving the perceptual experience of the smoking experience.
[0162] In another example, the permeability ratio is 50% to 85% to provide additional cooling to heated volatile components. In some cases, the permeability ratio can be at least 60% or 65%.
[0163] Figure 1 is a side cross-sectional view of article 1 for use in an aerosol delivery system.
[0164] Article 1 comprises a mouthpiece 2 and a cylindrical aerosol-generating material rod 3 connected to the mouthpiece 2. In embodiments of the present invention, the aerosol-generating composition comprises a first amorphous solid material and a second amorphous solid material. In some embodiments, the aerosol-generating composition comprises a plurality of strands and / or strips of tobacco material and a plurality of strips of amorphous solid material. In some embodiments, the aerosol-generating composition separately or additionally comprises at least one amorphous solid material sheet, for example, an amorphous solid material sheet circumscribing the aerosol-generating material rod 3, such as a plurality of strands and / or strips of tobacco material and a plurality of strips of amorphous solid material.
[0165] In this example, the aerosol-generating material rod 3 comprises strands and / or strips of a first amorphous solid material mixed with tobacco material to form the aerosol-generating material rod 3, and the second amorphous solid material 11 is provided in the form of a sheet and forms a wrap that circumsects the aerosol-generating material rod 3.
[0166] In other examples, the aerosol-generating material rod 3 does not contain amorphous solid material. In addition or alternatively, the aerosol-generating composition may include the aerosol-generating material rod 3, and one or more amorphous solid material sheets may be circumferential to the aerosol-generating material rod 3.
[0167] In this example, the first amorphous solid material is a menthol-containing dry gel, and the second amorphous solid material 11 is also a dry gel containing a larger amount of aerosol-forming agent by weight percentage than the first amorphous solid material. In alternative embodiments, each of the first amorphous solid material and the second amorphous solid material 11 may have any of the compositions described herein.
[0168] It is advantageous that the inventors have found that an improved article can be made comprising an aerosol-generating composition comprising a first component comprising tobacco material and a second component comprising amorphous solid, wherein the material properties (e.g., density) and specifications (e.g., thickness, length, and cross width) are within the range described herein. In embodiments of the present invention, the second component comprising amorphous solid comprises at least two amorphous solid materials. In this example, the first amorphous solid material comprises strands and / or strips which are mixed with tobacco material to form an aerosol-generating material rod 3, and the second amorphous solid material 11 is provided as a wrap circumferential to the aerosol-generating material rod 3. In alternative embodiments, both the first amorphous solid material and the second amorphous solid material 11 may be provided as a wrap circumferential to the aerosol-generating material rod 3.
[0169] In other examples, the first amorphous solid can be provided as strands and / or strips, which can be mixed with tobacco material to form aerosol-generating material rods 3, and the second amorphous solid material can be provided as capsules in a mouthpiece.
[0170] In some examples, multiple strands and / or strips of tobacco material and multiple strips of the first amorphous solid material may each have a length of at least about 5 mm. In some embodiments, the material properties and / or dimensions of at least two components may be selected in other ways to ensure that relatively uniform mixing of the components is possible and to reduce separation or non-mixing of the components during or after the manufacture of the aerosol-generating material rod 3.
[0171] Although described above in the form of a rod, the aerosol-generating composition can be provided in other forms, for example, as a plug, pouch, or packet of material within an article. The article may comprise consumables for an aerosol delivery system, such as the non-flammable aerosol delivery system described herein.
[0172] In this example, the tobacco material preferably includes recycled tobacco material. The tobacco material may also include any of the forms described herein by alternative or additional means. The tobacco material preferably contains 10% to 90% by weight of tobacco leaves, the aerosol-forming material is provided in an amount of up to about 10% by weight of tobacco leaves, and the remainder of the tobacco material consists of recycled tobacco.
[0173] In some cases, the first and second amorphous solid materials may each have a thickness of about 0.015 mm to about 1.0 mm. Preferably, the thickness can be in the range of about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm or 0.3 mm. The inventors have found that when the amorphous solid is provided as shredded amorphous solid material, a thickness of about 0.09 mm may be particularly suitable for the amorphous solid material. The inventors have found that when the amorphous solid material is provided as a wrap, a thickness of about 0.1 mm may be particularly suitable for the amorphous solid material 11. The amorphous solid may comprise two or more layers, and the thicknesses described herein refer to the total thickness of those layers.
[0174] The thickness of amorphous solid materials can be measured using a caliper or microscope, such as a scanning electron microscope (SEM) known to those skilled in the art, or any other suitable technique known to those skilled in the art.
[0175] The inventors have established that if the amorphous solid is too thick, heating efficiency may be impaired. This can negatively affect power consumption during use, for example, the power consumption required to release the fragrance from the amorphous solid. Conversely, if the amorphous solid forming the aerosol is too thin, it may be difficult to manufacture and handle, very thin materials may be more difficult to cast, may be brittle, and aerosol formation during use may be impaired. In some cases, individual strips or sections of amorphous solid have a minimum thickness of about 0.05 mm over their area. In some cases, individual strips or sections of amorphous solid have a minimum thickness of about 0.08 mm over their area. In some cases, individual strips or sections of amorphous solid have a maximum thickness of about 0.25 mm over their area. In some cases, individual strips or sections of amorphous solid have a maximum thickness of about 0.2 mm or about 0.15 mm over their area.
[0176] The inventors have found that when amorphous solid materials are included in an aerosol-generating composition as strands or strips of material, providing amorphous solid materials and tobacco materials having surface density values that differ from each other by a smaller proportion than a given ratio reduces the separation of mixtures of these materials. In some examples, the surface density of the amorphous solid material can be 50% to 150% of the surface density of the tobacco material. For example, the surface density of the amorphous solid material can be 60% to 140% of the surface density of the tobacco material, or 70% to 110%, or 80% to 120% of the surface density of the tobacco material.
[0177] To avoid misunderstanding, when the term "surface density" is used herein, it refers to the average surface density calculated with respect to a given strip, section, or sheet of amorphous solid material, which is calculated by measuring the surface area and weight of the given strip, section, or sheet of amorphous solid material.
[0178] In some cases, the thickness of an amorphous solid can vary by only 25%, 20%, 15%, 10%, 5%, or 1% or less over its area.
[0179] The amorphous solid in sheet form weighs approximately 30 g / m². 2 ~about 150g / m 2 It can have any preferred surface density, such as the above. In some cases, the sheet is about 55 g / m². 2 ~Approx. 135g / m 2 , or approximately 80-120g / m 2 , or approximately 70-110 g / m 2 , or especially about 90-110 g / m² 2 , or preferably about 68 g / m 2 Or approximately 83g / m 2 It can have a mass per unit area of approximately 30-90 g / m². These ranges can provide a density similar to that of shredded rag tobacco, and as a result, can provide a mixture of these materials that does not easily separate. Such surface densities may be particularly suitable when amorphous solid materials are included in aerosol products as shredded sheets. In some cases, the sheets have a mass of approximately 30-90 g / m². 2 40-85g / m 2 , or 50-65 g / m 2 It can have a mass per unit area and can be used to roll up aerosolizable materials such as cigarettes.
[0180] The density of the tobacco material affects the rate at which heat is transferred through the material. At lower densities, such as below 700 mg / cc, heat is transferred more slowly, allowing for a more sustained release of aerosols.
[0181] The tobacco material may include recycled tobacco material having a density of less than approximately 700 mg / cc, such as recycled paper tobacco material. For example, the aerosol-generating material 3 includes recycled tobacco material having a density of less than approximately 600 mg / cc. Alternatively or additionally, the aerosol-generating material 3 may include recycled tobacco material having a density of at least 350 mg / cc.
[0182] The tobacco material can be provided in the form of shredded rag tobacco. Shredded rag tobacco can have a cut width of at least 15 cuts per inch (approximately 5.9 cuts per cm, equivalent to a cut width of approximately 1.7 mm). Preferably, shredded rag tobacco has a cut width of at least 18 cuts per inch (approximately 7.1 cuts per cm, equivalent to a cut width of approximately 1.4 mm), and more preferably at least 20 cuts per inch (approximately 7.9 cuts per cm, equivalent to a cut width of approximately 1.27 mm). In one example, shredded rag tobacco has a cut width of 22 cuts per inch (approximately 8.7 cuts per cm, equivalent to a cut width of approximately 1.15 mm). Preferably, shredded rag tobacco has a cut width of 40 cuts per inch (approximately 15.7 cuts per cm, equivalent to a cut width of approximately 0.64 mm) or less. It has been found that a cutting width of 0.5 mm to 2.0 mm, for example 0.6 to 1.7 mm or 0.6 mm to 1.5 mm, yields a tobacco material that is particularly favorable in terms of the surface area-to-volume ratio of the aerosol-generating material rod 3, as well as the overall density and pressure drop, especially when heated. Shredded rag tobacco can be formed from a mixture of forms of tobacco material, such as a mixture of one or more of recycled tobacco, loose leaf tobacco, extruded tobacco, and band-cast tobacco. The tobacco material preferably contains recycled tobacco or a mixture of recycled tobacco and loose leaf tobacco.
[0183] The tobacco material can have any preferred thickness. The tobacco material can have a thickness of at least about 0.145 mm, for example, at least about 0.15 mm, or at least about 0.16 mm. The tobacco material can have a maximum thickness of about 0.25 mm, and for example, the thickness of the tobacco material can be less than about 0.22 mm or less than about 0.2 mm. In some embodiments, the tobacco material can have an average thickness in the range of 0.175 mm to 0.195 mm. Such thicknesses may be particularly preferred when the tobacco material is recycled tobacco material.
[0184] It may be desirable to provide an aerosol-generating composition comprising a mixture of at least two components, such as a first component comprising the tobacco material described herein and a second component comprising an amorphous solid material. Such an aerosol-generating composition can introduce additional fragrances to the aerosol-generating composition by including an amorphous solid material component, thereby supplying an aerosol with a desirable fragrance profile during use. The fragrance provided within the amorphous solid material can be retained more stably within the amorphous solid material compared to the fragrance added directly to the tobacco material, resulting in a more consistent fragrance profile among articles produced according to the present invention.
[0185] The second amorphous solid material may be included as a further component in the aerosol-generating composition, for example, as an amorphous solid material sheet circumscribing a rod containing the tobacco material and the first amorphous solid material. It is advantageous that the inventors have found that when the article contains the first and second amorphous solid materials described herein, it is possible to provide an improved aerosol by selecting the respective compositions and material properties of the amorphous solid materials to improve the aerosol characteristics. For example, the composition of the first amorphous solid material may be selected to achieve the delivery of a desired fragrance, and the composition of the second amorphous solid material may be selected to achieve the delivery of a specific aerosol-forming material. In other examples, the second amorphous solid material may be selected to achieve the delivery of a desired fragrance, and the composition of the first amorphous solid material may be selected to achieve the delivery of an improved aerosol-forming material. The form in which each of the first and second amorphous solid materials is contained in the article (e.g., shredded sheets or wrap) can be selected to allow for the volatilization of each component of the material at different stages of consumption of the article during use.
[0186] It is advantageous that the inventors have found that an improved aerosol can be obtained by selecting the form, location, and composition of the first and second amorphous solids described herein. For example, the inventors have found that by providing the first amorphous solid surrounding the second amorphous solid, it is possible to suitably select the locations of both amorphous solid materials for the optimization of specific parameters of the aerosol. For example, by providing the amorphous solid material in a high-flow region of the article, the release of flavorings from the amorphous solid material can be increased. Similarly, one of the amorphous solid materials can be located closer to the heat source than the other amorphous solid material, thereby improving the release of the aerosol-forming material from the amorphous solid material closer to the heater. It is preferable that the first amorphous solid material containing the aerosol-forming material be located closer to the heat source than the second amorphous solid material, thereby increasing the release of the aerosol-forming material from the first amorphous solid material.
[0187] The form in which the amorphous solid material is provided can also affect the rate and amount of release of aerosolizable components of the amorphous solid, such as aerosol-forming materials or active substances. For example, by providing the amorphous solid as shredded sheets within an aerosol-generating composition, the surface area of the amorphous solid through which aerosols absorbed through the article during use can be increased compared to the amorphous solid material provided as a wrap. Thus, providing the amorphous solid material as shredded sheets can improve the release of flavorings from the amorphous solid material. For example, if a smaller exposed surface area is desirable to provide a more sustained release of components of the amorphous solid material, the amorphous solid material can be provided as a wrap in the form of a sheet.
[0188] In one exemplary configuration, a first amorphous solid material containing an aerosol-forming agent in a larger amount by weight percentage than a second amorphous solid material is provided as a sheet circumferential to an aerosol-generating composition rod, and the aerosol-generating composition contains the second amorphous solid material in the form of shredded sheets. Both the first and second amorphous solid materials may contain an active substance. It is advantageous that the inventors have found that when the first amorphous solid is positioned closer to the heat source, the active substance, such as a flavoring, can be more easily volatilized from the first amorphous solid material, and when the second amorphous solid is positioned further away from the heat source, a more sustained release of the active substance can be obtained.
[0189] In further exemplary articles, the first amorphous solid material may be provided as a shredded sheet, and the second amorphous solid material may be provided as a wrap.
[0190] In further exemplary articles, both the first and second amorphous solid materials may be provided in sheet form and may be circumferential to an aerosol-generating composition rod. A sheet or layer of the first amorphous solid material may be superimposed on a sheet or layer of the second amorphous solid material. In alternative exemplary articles, a sheet or layer of the second amorphous solid material may also be superimposed on a sheet or layer of the first amorphous solid material.
[0191] As described above, it is advantageous that tobacco materials having densities of at least 350 mg / cc and less than approximately 700 mg / cc have been found to result in a more sustained aerosol release. To supply an aerosol with a consistent aroma profile, it may be desirable to uniformly disperse the amorphous solid material components of the aerosol-generating composition along the rod. When one of the first or second amorphous solid materials is included in the aerosol-generating composition as a shredded sheet, it is advantageous that the inventors have found that this can be achieved by casting the amorphous solid material to have the thickness described herein and processing the amorphous solid material as described later to ensure a uniform distribution throughout the entire aerosol-generating material rod 3, thereby providing an amorphous solid material having a surface density similar to that of the tobacco material.
[0192] It is advantageous that the inventors have found that when an amorphous solid material in sheet form is shredded, a sufficiently uniform mixture of tobacco material components and amorphous solid material components can be achieved. The cutting width of the shredded amorphous solid material is preferably 0.75 mm to 2 mm, for example, 1 mm to 1.5 mm. In addition to the cutting width, the cutting length of the shredded amorphous solid material can be defined by cutting the strands of amorphous solid material formed by shredding in the width direction, for example, in a cross-cut shredding process. The cutting length of the shredded amorphous solid material is preferably at least 2 mm, for example, 2 mm to 5 mm, at least 2.5 mm, or at least 3 mm. In some examples, the cutting length of the shredded amorphous solid material is at least 10 mm or at least 20 mm. The cutting length of the shredded amorphous solid material can be less than 60 mm, less than 50 mm, or less than 40 mm. In some examples, at least 90% of the pieces of shredded amorphous solid material in an article have a cutting length of about 2 mm to about 40 mm or about 2 mm to about 25 mm. It has been found to be advantageous that the cutting lengths of the shredded amorphous solid material are non-uniform in order to achieve uniform mixing of the shredded amorphous solid material and shredded rag tobacco. The length of the pieces or strips of amorphous solid material, referred to as cutting length, may be determined by the dimensions of the material determined during its manufacture, for example, the width of the sheet of material at the time of manufacture.
[0193] In some embodiments, a plurality of strips of amorphous solid material are provided, and at least one of the plurality of strips of amorphous solid material has a length greater than about 10 mm. Alternatively or additionally, at least one of the plurality of strips of amorphous solid material may have a length of about 10 mm to about 60 mm or about 20 mm to about 50 mm. Each of the plurality of strips of amorphous solid material may have a length of about 10 mm to about 60 mm or about 20 mm to about 50 mm.
[0194] The aerosol-generating material rod 3 preferably comprises a first component containing tobacco material in an amount of 50% to 98%, for example, 80% to 95%, and a second component containing shredded amorphous solid material in an amount of 2% to 50%, for example, 5% to 20%, when the tobacco material is provided as shredded rag tobacco. For example, the aerosol-generating material rod may contain 85% by weight of tobacco material and 11% by weight of amorphous solid material. Alternatively, the aerosol-generating material rod may contain about 80% tobacco material and about 20% shredded amorphous solid material.
[0195] The aerosol-generating composition can be provided in the form of a rod having a first end and a second end. The portion of the rod between the first end and an intermediate longitudinal position between the first and second ends may contain 20% to 80% of the amorphous solid material within the rod.
[0196] The aerosol-generating composition is preferably provided as a cylindrical rod of aerosol-generating material. Regardless of the form of the aerosol-generating composition, it is preferable that the aerosol-generating composition has a length of about 10 mm to 100 mm. In some embodiments, the length of the aerosol-generating composition is preferably in the range of about 25 mm to 50 mm, more preferably about 30 mm to 45 mm, and even more preferably about 30 mm to 40 mm.
[0197] The volume of the aerosol-generating material provided is approximately 200 mm³. 3 ~Approximately 4300mm 3 Preferably about 500 mm 3 ~1500mm 3 , more comfortably approximately 1000mm 3 ~approximately 1300mm 3 These volumes can vary. For example, about 1000 mm³. 3 ~approximately 1300mm 3It is advantageous that the aerosol-generating composition has been shown to produce a superior aerosol with greater visibility and perceptual performance compared to those achieved in selected volumes from the lower end of this range.
[0198] The mass of the aerosol-generating composition provided can be greater than 200 mg, for example, about 200 mg to 400 mg, preferably about 230 mg to 360 mg, and more preferably about 250 mg to 360 mg. Providing a larger mass aerosol-generating composition has been found to result in improved perceptual performance compared to aerosols produced from smaller mass tobacco materials, which is advantageous.
[0199] In this example, the mouthpiece 2 includes a material body 6 upstream of a hollow tubular element 4, and in this example, the material body 6 is adjacent to and in contact with the hollow tubular element 4. The material body 6 and the hollow tubular element 4 each define a substantially cylindrical overall outer shape and share a common longitudinal axis. The material body 6 is encased in a first plug wrap 7. The first plug wrap 7 preferably has a basis weight of less than 50 gsm, more preferably about 20 gsm to 40 gsm. The first plug wrap 7 preferably has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The first plug wrap 7 is a non-porous plug wrap and preferably has a permeability of, for example, less than 100 cholesta units, for example less than 50 cholesta units. However, in other embodiments, the first plug wrap 7 can be a porous plug wrap and have a permeability of, for example, greater than 200 cholesta units.
[0200] The length of material body 6 is preferably less than about 15 mm. More preferably less than about 10 mm. In addition, or alternatively, the length of material body 6 is at least about 5 mm. The length of material body 6 is preferably at least about 6 mm. In some preferred embodiments, the length of material body 6 is about 5 mm to about 15 mm, more preferably about 6 mm to about 12 mm, even more preferably about 6 mm to about 12 mm, most preferably about 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. In this example, the length of material body 6 is 10 mm.
[0201] In this example, material 6 is formed from filament tow. In this example, the tow used in material 6 has 8.4 denier per filament (dpf) and 21,000 total denier. Alternatively, the tow may have, for example, 9.5 denier per filament (dpf) and 12,000 total denier. In this example, the tow includes tow made of plasticized cellulose acetate. The plasticizer used in the tow accounts for about 7% by weight of the tow. In this example, the plasticizer is triacetin. In other examples, material 6 may be formed using different materials. For example, instead of tow, material 6 may be formed from paper, for example, in a manner similar to that of paper filters known for use in cigarettes. Alternatively, material 6 may be formed from tow other than cellulose acetate, for example, polylactic acid (PLA), other materials described herein with respect to filament tow, or similar materials. The tow, whether formed from cellulose acetate or another material, preferably has a dpf of at least 5, more preferably at least 6, and even more preferably at least 7. These denier-per-filament values provide a tow with relatively coarser and thicker fibers and a smaller surface area, resulting in a smaller pressure drop in the mouthpiece 2 than a tow with a lower dpf value. To achieve a sufficiently uniform material body 6, the tow preferably has a denier-per-filament of 12 d.pf or less, preferably 11 d.pf or less, and even more preferably 10 d.pf or less.
[0202] The total denier of the tow forming the material body 6 is preferably at most 30,000, more preferably at most 28,000, and even more preferably at most 25,000. These total denier values provide a tow that occupies a smaller proportion of the cross-sectional area of the mouthpiece 2, resulting in a smaller pressure drop in the mouthpiece 2 than with a tow having a higher total denier value. For a material body 6 of appropriate stiffness, the tow preferably has a total denier of at least 8,000, more preferably at least 10,000. The denier per filament is preferably 5 to 12, and the total denier is preferably 10,000 to 25,000. The denier per filament is more preferably 6 to 10, and the total denier is preferably 11,000 to 22,000. The cross-sectional shape of the tow filaments is preferably "Y" shaped, but in other embodiments, other shapes such as "X" shaped filaments having the same dpf and total denier values provided herein may also be used. As shown in Figure 1, the mouthpiece 2 of article 1 comprises an upstream end 3a adjacent to the aerosol-generating material rod 3 and a downstream end 3b away from the aerosol-generating material rod 3. The mouthpiece 2 has a hollow tubular element 4 formed from a filament tow at the downstream end 3b. This has been found to be advantageous in that it significantly reduces the temperature of the outer surface of the mouthpiece 2 at the downstream end 3b that comes into contact with the consumer's mouth. In addition, the use of the tubular element 4 has also been found to significantly reduce the temperature of the outer surface of the mouthpiece 2 upstream of the tubular element 4. Although we do not wish to be constrained by theory, it is assumed that this is due to the tubular element 4 causing the aerosol to pass closer to the center of the mouthpiece 2, and therefore reducing heat transfer from the aerosol to the outer surface of the mouthpiece 2.
[0203] In this example, article 1 has a circumference of approximately 21 mm (i.e., the article is demi-slim). In other examples, the article may be provided in any of the forms described herein, for example, having a circumference of 15 mm to 25 mm. Since the article is heated to release aerosols, improved heating efficiency can be achieved by using articles with smaller circumferences within this range, for example, less than 23 mm. To achieve improved aerosols by heating while maintaining a suitable product length, circumferences of articles greater than 19 mm have also been found to be particularly effective. Articles with circumferences of 19 mm to 23 mm, more preferably 20 mm to 22 mm, have been found to offer a good balance that allows for efficient heating while providing effective aerosol delivery.
[0204] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the aerosol-generating material rod 3, and therefore the transition between these components is smooth. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm. Tip paper 5 is wrapped around a portion of the aerosol-generating material rod 3 along the entire length of the mouthpiece 2, and the tip paper 5 has an adhesive on its inner surface to connect the mouthpiece 2 and the rod 3. In this example, the tip paper 5 extends 5 mm over the aerosol-generating material rod 3, but alternatively, it may extend 3 mm to 10 mm, or more preferably 4 mm to 6 mm, over the rod 3 to provide a secure attachment between the mouthpiece 2 and the rod 3. The tip paper 5 may have a larger basis weight than the plug wrap used in article 1, for example 40 gsm to 80 gsm, more preferably 50 gsm to 70 gsm, 58 gsm in this example. As a result of these basis weight ranges, it was found that a tip paper with sufficient flexibility to wrap around article 1 and adhere to the tip paper itself along the longitudinal lap seam of the paper was obtained, while possessing acceptable tensile strength. After being wrapped around mouthpiece 2, the circumference of tip paper 5 is approximately 21 mm.
[0205] The "wall thickness" of the hollow tubular element 4 corresponds to the thickness of the wall of the tube 4 in the radial direction. This can be measured, for example, using a caliper. It is advantageous for the wall thickness to be greater than 0.9 mm, and more preferably 1.0 mm or more. It is preferable that the wall thickness is substantially constant throughout the wall of the hollow tubular element 4. However, if the wall thickness is not substantially constant, the wall thickness is preferably greater than 0.9 mm, and more preferably 1.0 mm or more, at any point around the hollow tubular element 4.
[0206] The length of the hollow tubular element 4 is preferably less than about 20 mm. More preferably, the length of the hollow tubular element 4 is less than about 15 mm. Even more preferably, the length of the hollow tubular element 4 is less than about 10 mm. In addition or alternatively, the length of the hollow tubular element 4 is at least about 5 mm. The length of the hollow tubular element 4 is preferably at least about 6 mm. In some preferred embodiments, the length of the hollow tubular element 4 is about 5 mm to about 20 mm, more preferably about 6 mm to about 10 mm, even more preferably about 6 mm to about 8 mm, most preferably about 6 mm, 7 mm, or about 8 mm. In this example, the length of the hollow tubular element 4 is 6 mm.
[0207] The density of the hollow tubular element 4 is preferably at least about 0.25 grams per cubic centimeter (g / cc), more preferably at least about 0.3 g / cc. The density of the hollow tubular element 4 is preferably less than about 0.75 grams per cubic centimeter (g / cc), more preferably less than 0.6 g / cc. In some embodiments, the density of the hollow tubular element 4 is 0.25 to 0.75 g / cc, more preferably 0.3 to 0.6 g / cc, more preferably 0.4 g / cc to 0.6 g / cc or about 0.5 g / cc. These densities have been found to provide a good balance between the improved stiffness given by the higher density material and the lower heat transfer properties of the lower density material. For the purposes of the present invention, the "density" of the hollow tubular element 4 refers to the density of the filament tow forming the element into which some plasticizer is incorporated. The density can be determined by dividing the total weight of the hollow tubular element 4 by the total volume of the hollow tubular element 4, which can be calculated using appropriate measurements of the hollow tubular element 4, for example, obtained using a caliper. If necessary, appropriate dimensions can be measured using a microscope.
[0208] The filament tow forming the hollow tubular element 4 preferably has a total denier of less than 45,000, more preferably less than 42,000. This total denier has been found to allow for the formation of tubular elements 4 that are not too dense. The total denier is preferably at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filament tow forming the hollow tubular element 4 has a total denier of 25,000 to 45,000, more preferably 35,000 to 45,000. The cross-sectional shape of the tow filament is preferably "Y" shaped, but in other embodiments, other shapes such as "X" shaped filaments may be used.
[0209] The filament tow forming the hollow tubular element 4 preferably has a denier per filament greater than 3. This denier per filament has been found to allow for the formation of tubular elements 4 that are not too dense. The denier per filament is preferably at least 4, more preferably at least 5. In a preferred embodiment, the filament tow forming the hollow tubular element 4 has a denier per filament of 4 to 10, more preferably 4 to 9. In one example, the filament tow forming the hollow tubular element 4 has an 8Y40,000 tow formed from cellulose acetate and contains 18% plasticizer, such as triacetin.
[0210] The hollow tubular element 4 preferably has an inner diameter greater than 3.0 mm. A smaller diameter may increase the velocity of the aerosol that passes through the mouthpiece 2' to the consumer's mouth more than desired, resulting in the aerosol becoming too hot, for example, reaching temperatures greater than 40°C or 45°C. The hollow tubular element 4 more preferably has an inner diameter greater than 3.1 mm, and even more preferably greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular element 4 is about 3.9 mm.
[0211] The hollow tubular element 4 preferably contains 15% to 22% by weight of a plasticizer. In the case of cellulose acetate tow, the plasticizer is preferably triacetin, but other plasticizers such as polyethylene glycol (PEG) may also be used. The tubular element 4 more preferably contains 16% to 20% by weight of a plasticizer, for example, about 17%, about 18%, or about 19% of a plasticizer.
[0212] In this example, the hollow tubular element 4 is the first hollow tubular element 4, and the mouthpiece includes a second hollow tubular element 8, also called a cooling element, upstream of the first hollow tubular element 4. In this example, the second hollow tubular element 8 is located upstream of the material body 6, adjacent to the material body 6, and in contact with the material body 6. The material body 6 and the second hollow tubular element 8 each define a substantially cylindrical overall outer shape and share a common longitudinal axis. The second hollow tubular element 8 is formed from multiple layers of paper, which are rolled in parallel and joined at the seams to form the tubular element 8. In this example, the first and second paper layers are provided as a double tube, but in other examples, three, four, or more paper layers may be used to form triple, quadruple, or more tubes. Other structures may also be used, such as spirally rolled paper layers, cardboard tubes, tubes formed using paper mache-type processes, and molded or extruded plastic tubes. The second hollow tubular element 8 can also be formed using a rigid plug wrap and / or tip paper as the second plug wrap 9 and / or tip paper 5 described herein, meaning that a separate tubular element is not required. The rigid plug wrap and / or tip paper is manufactured to have sufficient rigidity to withstand axial compressive forces and bending moments that may occur during manufacturing and in use of Article 1. For example, the rigid plug wrap and / or tip paper may have a basis weight of 70 gsm to 120 gsm, more preferably 80 gsm to 110 gsm. In addition or alternatively, the rigid plug wrap and / or tip paper may have a thickness of 80 μm to 200 μm, more preferably 100 μm to 160 μm, or 120 μm to 150 μm. To achieve an acceptable overall level of rigidity for the second hollow tubular element 8, it may be desirable that both the second plug wrap 9 and tip paper 5 have values within these ranges.
[0213] The second hollow tubular element 8 preferably has a wall thickness that can be measured in the same way as the first hollow tubular element 4, where the wall thickness of the second hollow tubular element 8 is at least about 100 μm and a maximum of about 1.5 mm, preferably 100 μm to 1 mm, more preferably 150 μm to 500 μm, or about 300 μm. In this example, the second hollow tubular element 8 has a wall thickness of about 290 μm.
[0214] The length of the second hollow tubular element 8 is preferably less than about 50 mm. More preferably, the length of the second hollow tubular element 8 is less than about 40 mm. Even more preferably, the length of the second hollow tubular element 8 is less than about 30 mm. In addition or alternatively, the length of the second hollow tubular element 8 is preferably at least about 10 mm. The length of the second hollow tubular element 8 is preferably at least about 15 mm. In some preferred embodiments, the length of the second hollow tubular element 8 is about 20 mm to about 30 mm, more preferably about 22 mm to about 28 mm, even more preferably about 24 mm to about 26 mm, and most preferably about 25 mm. In this example, the length of the second hollow tubular element 8 is 25 mm.
[0215] The second hollow tubular element 8 is positioned around and defines a void within the mouthpiece 2 that acts as a cooling segment. The void provides a chamber through which heated volatile components generated by the aerosol-generating composition flow. The second hollow tubular element 8 is hollow and provides a chamber for the aerosol reservoir that is still rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and use of article 1. The second hollow tubular element 8 provides a physical displacement between the aerosol-generating composition and the material body 6. The physical displacement provided by the second hollow tubular element 8 provides a temperature gradient along the length of the second hollow tubular element 8.
[0216] Mouthpiece 2 is 450mm 3It is preferable to have a cavity with a larger internal volume. It has been found that providing a cavity of at least this volume enables improved aerosol formation. Such a cavity size provides sufficient space within the mouthpiece 2 to allow the heated volatile components to cool, thus allowing exposure of the aerosol-generating composition to a temperature higher than would otherwise be possible, which could result in overheated aerosols. In this example, the cavity is formed by a second hollow tubular element 8, but in alternative configurations, it may also be formed within a different part of the mouthpiece 2. It is more preferable that the mouthpiece 2 has a cavity formed, for example, within the second hollow tubular element 8, where this cavity is 500 mm 3 Larger, even more preferably 550mm 3 It has a larger internal volume, allowing for further improvement of aerosols. In some examples, the internal cavity is approximately 550 mm 3 ~about 750mm 3 For example, about 600mm 3 Or 700mm 3 It includes the volume of.
[0217] The second hollow tubular element 8 can be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the second hollow tubular element 8 and the heated volatile components exiting the second downstream end of the second hollow tubular element 8. Preferably, the second hollow tubular element 8 is configured to provide a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius between the heated volatile components entering the first upstream end of the second hollow tubular element 8 and the heated volatile components exiting the second downstream end of the second hollow tubular element 8. This temperature difference along the length of the second hollow tubular element 8 protects the temperature-sensitive material body 6 from the high temperature of the aerosol-generating composition when heated.
[0218] In the alternative article, the second hollow tubular element 8 can be replaced with an alternative cooling element, for example, an element formed from a material that performs the function of cooling the aerosol while allowing the aerosol to pass longitudinally.
[0219] In this example, the first hollow tubular element 4, the material body 6, and the second hollow tubular element 8 are combined using a second plug wrap 9 wrapped around all three sections. The second plug wrap 9 preferably has a basis weight of less than 50 gsm, more preferably about 20 gsm to 45 gsm. The second plug wrap 9 preferably has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The second plug wrap 9 is preferably a non-porous plug wrap with a permeability of less than 100 cholesta units, for example, less than 50 cholesta units. However, in alternative embodiments, the second plug wrap 9 may also be a porous plug wrap with a permeability of, for example, greater than 200 cholesta units.
[0220] In this example, the aerosol-generating material 3 is wound within a roll of paper 10. The roll of paper 10 can be, for example, paper or paper-backed foil. In this example, the roll of paper 10 is substantially impermeable to air. In alternative embodiments, the roll of paper 10 preferably has a permeability of less than 100 cholesta units, more preferably less than 60 cholesta units. For example, low-permeability roll of paper having a permeability of less than 100 cholesta units, more preferably less than 60 cholesta units, has been found to result in improved aerosol formation within the aerosol-generating material 3. While we do not wish to be constrained by theory, this is assumed to be due to a reduction in the loss of aerosol compounds in the roll of paper 10. The permeability of the roll of paper 10 can be measured according to ISO 2965:2009 for determining the permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.
[0221] In this embodiment, the roll paper 10 includes aluminum foil. The aluminum foil has been found to be particularly effective in promoting aerosol formation within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer having a thickness of about 6 μm. In this example, the aluminum foil has a paper backing. However, in alternative configurations, the aluminum foil may have other thicknesses, for example, 4 μm to 16 μm. The aluminum foil also does not need to have a paper backing and may have a backing formed from other materials, for example, to help provide the foil with appropriate tensile strength, or it may not have a backing material at all. Metal layers or foils other than aluminum may also be used. The total thickness of the roll paper is preferably 20 μm to 60 μm, more preferably 30 μm to 50 μm, which provides a roll paper with appropriate structural integrity and heat transfer properties. The tensile force that can be applied to the roll of paper before it tears can be greater than 3,000 grams, for example, between 3,000 and 10,000 grams, or between 3,000 and 4,500 grams.
[0222] The article has a ventilation level of approximately 75% of the aerosol inhaled through the article. In an alternative embodiment, the article may have a ventilation level of 50% to 80%, for example, 65% to 75%, of the aerosol inhaled through the article. These levels of ventilation help to slow down the flow of aerosol inhaled through the mouthpiece 2, thereby allowing the aerosol to cool sufficiently before reaching the downstream end 3b of the mouthpiece 2. The ventilation is provided directly into the mouthpiece 2 of the article 1. In this example, the ventilation is provided into a second hollow tubular element 8, which has been found to be particularly beneficial in assisting the aerosol generation process. The ventilation is provided through first and second parallel rows of perforations 12, in this case formed as laser perforations at positions 17.925 mm and 18.625 mm, respectively, from the downstream mouth end 3b of the mouthpiece 2. These perforations pass through the tip paper 5, the second plug wrap 9, and the second hollow tubular element 8. In an alternative embodiment, ventilation may also be provided elsewhere into the mouthpiece, for example, into the material body 6 or the first tubular element 4.
[0223] Figure 2 is a side cross-sectional view of a further article 1' including a mouthpiece 2. Article 1' is substantially the same as article 1, except that in this example the aerosol-generating composition includes a first amorphous solid material sheet 12 that circumscribes the aerosol-generating material rod 3' and a second amorphous solid material 11 that overlaps the first amorphous solid material sheet 12.
[0224] It is advantageous that, as a result of the inventors providing both a first amorphous solid material and a second amorphous solid material as wraps, the article can contain an increased amount of desirable components, such as active substances or aerosol-forming materials, compared to the same volume of article in which one or both of the first and second amorphous solid materials are provided as shredded sheets within the aerosol-generating composition. For example, when the first and second amorphous solid materials are provided as wraps for a given volume of aerosol-generating composition, the volume available for other aerosol-generating materials is not reduced as much as when the same mass of the first or second amorphous solid material is provided as shredded sheets and mixed with the aerosol-generating material. As a result, the overall delivery of desirable components of the aerosol can be increased for a given article size.
[0225] In this example, the aerosol-generating material rod 3' does not contain amorphous solid material, but in other examples, the aerosol-generating composition may include a first amorphous solid material sheet 11 and a second amorphous solid material sheet 12, as well as shredded amorphous solid material in the aerosol-generating composition rod 3.
[0226] In some cases, a first amorphous solid material can be laminated on top of a second amorphous solid material.
[0227] In this example, the first amorphous solid material 11 and the second amorphous solid material 12 have different compositions. In alternative embodiments, the first and second amorphous solid materials may have the same composition, material properties, and specifications, or they may differ in any of these parameters.
[0228] As described above, in order to provide an aerosol with a consistent fragrance profile, it may be desirable to uniformly disperse the amorphous solid material components of the aerosol-generating composition along the length of the components. In some examples, this can be achieved by including a first amorphous solid material 11 and a second amorphous solid material 12 as wraps in the form of sheets, with each wrap circumscribing the entire length of the aerosol-generating composition rod 3'. In other examples, the first or second amorphous solid material sheets 12, 11 may be arranged so as to extend only partially along the length of the aerosol-generating material rod 3'.
[0229] Figure 3a is a side cross-sectional view of a further article 1” including a capsule-containing mouthpiece 2’. Figure 3b is a cross-sectional view of the capsule-containing mouthpiece shown in Figure 3a, cut along line A-A’ in Figure 3a. Article 1” and capsule-containing mouthpiece 2’ are the same as article 1 and mouthpiece 2 shown in Figure 1, except that the aerosol modifier is provided in a material body 6 in the form of a capsule 14 in this example, and an oil-resistant first plug wrap 7’ surrounds the material body 6. In other examples, the aerosol modifier can be provided in other forms, such as a material injected into the material body 6, or a material provided in a thread, for example, the thread may hold a flavoring or other aerosol modifier, and the aerosol modifier may also be placed within the material body 6.
[0230] In some examples, the first amorphous solid material is provided within the aerosol-generating material rod 3, and the capsule 14 contains the second amorphous solid material. For example, the capsule shell and / or core may contain the amorphous solid material.
[0231] The capsule 14 can constitute a destructible capsule, for example, a capsule having a solid, brittle shell surrounding a liquid payload. In this example, a single capsule 14 is used. The capsule 14 is entirely embedded within the material body 6. In other words, the capsule 14 is completely surrounded by the material forming the material body 6. In other examples, multiple destructible capsules, for example, two, three, or more destructible capsules, can be placed within the material body 6. The length of the material body 6 can be increased to accommodate the number of capsules required. In examples where multiple capsules are used, the individual capsules can be the same as or different from each other in terms of size and / or capsule payload. In other examples, multiple material bodies 6 can be provided, each containing one or more capsules.
[0232] The capsule 14 has a core-shell structure. In other words, the capsule 14 comprises a shell enclosing a liquid agent, such as a flavoring or other active substance, the liquid agent may be any one of the flavorings or aerosol modifiers described herein. The capsule shell can be ruptured by the user to release the flavoring or other active substance into the material body 6. The first plug wrap 7' may constitute a barrier coating to make the material of the plug wrap substantially impermeable to the liquid payload of the capsule 14. Alternatively or additionally, the second plug wrap 9 and / or tip paper 5 may constitute a barrier coating to make the material of the plug wrap and / or tip paper substantially impermeable to the liquid payload of the capsule 14.
[0233] In this example, capsule 14 is spherical and has a diameter of approximately 3 mm. In other examples, capsules of other shapes and sizes may be used. The total weight of capsule 14 can be in the range of approximately 10 mg to approximately 50 mg.
[0234] In this example, the capsule 14 is positioned at the longitudinal center within the material body 6. That is, the capsule 14 is positioned so that its center is 4 mm away from each end of the material body 6. In other examples, the capsule 14 can be positioned at a location other than the longitudinal center within the material body 6, that is, it can be positioned closer to the downstream end than the upstream end of the material body 6, or closer to the upstream end than the downstream end of the material body 6. Preferably, the mouthpiece 2' is configured such that the capsule 14 and the vent hole 13 are offset from each other in the longitudinal direction within the mouthpiece 2'.
[0235] A cross-sectional view of the mouthpiece 2' is shown in Figure 3b, which is a section of Figure 3a taken along the line A-A'. Figure 3b shows the capsule 14, the material body 6, the first plug wrap 7' and the second plug wrap 9, and the tip paper 5. In this example, the capsule 14 is located at the center of the longitudinal axis (not shown) of the mouthpiece 2'. The first plug wrap 7' and the second plug wrap 9 and the tip paper 5 are arranged concentrically around the material body 6.
[0236] The destructible capsule 14 has a core-shell structure; that is, the encapsulating material or barrier material forms a shell around a core containing the aerosol modifier. The shell structure prevents the movement of the aerosol modifier during storage of article 1" but allows for the controlled release of the aerosol modifier, also called the aerosol modifier, during use.
[0237] In some cases, the barrier material (also referred to herein as the encapsulating material) is brittle. The capsule is crushed or otherwise damaged or destroyed by the user to release the encapsulated aerosol modifier. Typically, the capsule is destroyed just before heating begins, but the user can choose when to release the aerosol modifier. The term “destructible capsule” refers to a capsule whose shell can be broken by pressure to release the core, more specifically, the shell can be ruptured under pressure applied by the user’s finger when the user wishes to release the capsule’s core.
[0238] In some cases, the barrier material is heat-resistant. That is, in some cases, the barrier will not burst, melt, or otherwise collapse at the temperature reached at the capsule site during operation of the aerosol supply device. Explanatoryly, the capsule placed in the mouthpiece can be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material can continue to hold the liquid core up to at least about 50°C to 120°C.
[0239] In other cases, when heated, the capsule releases the core composition, for example, by the melting of the barrier material or by the expansion of the capsule causing the barrier material to rupture.
[0240] The total weight of the capsule can be in the range of approximately 1 mg to approximately 100 mg, preferably approximately 5 mg to approximately 60 mg, approximately 8 mg to approximately 50 mg, approximately 10 mg to approximately 20 mg, or approximately 12 mg to approximately 18 mg.
[0241] The total weight of the core formulation can be in the range of approximately 2 mg to approximately 90 mg, preferably approximately 3 mg to approximately 70 mg, approximately 5 mg to approximately 25 mg, approximately 8 mg to approximately 20 mg, or approximately 10 mg to approximately 15 mg.
[0242] The capsule according to the present invention comprises the core described above and a shell. The capsule can exhibit a crushing strength of about 4.5 N to about 40 N, more preferably about 5 N to about 30 N or about 28 N (for example, about 9.8 N to about 24.5 N). The capsule bursting strength can be measured when the capsule is removed from the material body 6, and a force gauge is used to measure the force at which the capsule is pressed between two flat metal plates and bursts. A preferred measuring device is the Sauter FK50 force gauge, which has a flat attachment on its head, and can be used to press the capsule against a flat, hard surface having a surface similar to the attachment.
[0243] The capsules can be substantially spherical and may have a diameter of at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm, or 3.0 mm. The diameter of the capsule may be less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5 mm, 5.0 mm, 4.5 mm, 4.0 mm, 3.5 mm, or 3.2 mm. Explanatoryly, the capsule diameter may be in the range of about 0.4 mm to about 10.0 mm, about 0.8 mm to about 6.0 mm, about 2.5 mm to about 5.5 mm, or about 2.8 mm to about 3.2 mm. In some cases, the capsule may have a diameter of about 3.0 mm. These sizes are particularly suitable for incorporating the capsule into the articles described herein.
[0244] In some embodiments, the cross-sectional area of the capsule 14 at its maximum cross-sectional area is less than 28%, more preferably less than 27%, and even more preferably less than 25% of the cross-sectional area of the portion of the mouthpiece 2' in which the capsule 14 is provided. For example, in the case of a spherical capsule with a diameter of 3.0 mm, the maximum cross-sectional area of the capsule is 7.07 mm². 2 In the case of the mouthpiece 2' having a circumference of 21 mm as described herein, the material body 6 has an outer circumference of 20.8 mm, the radius of this component is 3.31 mm, and 34.43 mm 2This corresponds to the cross-sectional area of the mouthpiece 2'. In this example, the cross-sectional area of the capsule is 20.5% of the cross-sectional area of the mouthpiece 2'. As another example, if the capsule has a diameter of 3.2 mm, its maximum cross-sectional area is 8.04 mm². 2 This should be the case. In this case, the cross-sectional area of the capsule should be 23.4% of the cross-sectional area of the material 6. Having the maximum cross-sectional area of the capsule be less than 28% of the cross-sectional area of the portion of the mouthpiece 2' to which the capsule 14 is provided has the advantage, compared to a capsule with a larger cross-sectional area, that the pressure drop in the mouthpiece 2' is reduced, leaving sufficient space around the capsule for the aerosol to pass through, and the material 6 does not remove a large amount of aerosol mass as it passes through the mouthpiece 2'.
[0245] When the capsule is broken, the pressure drop or pressure difference (also called suction resistance) in the article, measured as the open pressure drop (i.e., with the vent opening open), preferably drops to less than 8 mmH2O. The open pressure drop is more preferably reduced to less than 6 mmH2O, and more preferably to less than 5 mmH2O. These values are measured as the average achieved by at least 80 articles made of the same design. Such small changes in pressure drop mean that other aspects of the product design can be realized, such as setting an appropriate vent level for a given product pressure drop, regardless of whether the consumer chooses to break the capsule or not.

[0261] Any suitable solvent can be used.
[0262] When the aerosol modifier contains flavorings, the solvent preferably contains short-chain or medium-chain fatty acids and oils. For example, the solvent may contain triesters of glycerol such as C2-C12 triglycerides, preferably C6-C10 triglycerides, or Cs-C12 triglycerides. For example, the solvent may contain medium-chain triglycerides (MCT-C8-C12) that can be derived from palm oil and / or coconut oil.
[0263] Esters can be formed with caprylic and / or capric acid. For example, the solvent may include medium-chain triglycerides of glyceryl tricaprylate and / or glyceryl tricaprate. For example, the solvent may include compounds identified by CAS registry numbers 73398-61-5, 65381-09-1, and 85409-09-2. Such medium-chain triglycerides are odorless and tasteless.
[0264] The hydrophilic-lipophilic balance (HLB) of the solvent can be in the range of 9 to 13, preferably 10 to 12. The method for producing the capsules includes co-extrusion, optionally followed by centrifugation and curing and / or drying. The contents of International Publication No. 2007 / 010407 are incorporated by reference as a whole.
[0265] In some examples, the article comprises an aerosol-generating material containing tobacco material and a first amorphous solid material, and a capsule in a mouthpiece containing a second amorphous solid material. In such examples, it is advantageous that the first amorphous solid material, tobacco material, and capsule may contain a flavoring agent and an aerosol-forming material, or both a flavoring agent and an aerosol-forming material. For example, a flavoring agent such as menthol can be added to the tobacco material, providing further flavoring agents within the first amorphous solid material. This combination can provide a desirable sensory experience for the user over the duration of use of the article. For example, a flavoring agent on the tobacco material can readily volatilize, providing a first stage of sensory experience immediately after the user begins using the article. A flavoring agent contained in the first amorphous solid material can provide a sustained release of flavor over the duration of use of the article, providing the user with a second stage of sensory experience. Further flavoring agents can also be provided within the capsule containing the second amorphous solid material, providing the article with an optional additional flavor during use, providing the user with a third stage of sensory experience.
[0266] In other examples, the first amorphous solid material, the tobacco material, and the capsule may each include an aerosol-forming material.
[0267] In the example described above, mouthpieces 2 and 2' each comprise a single material body 6. In other examples, the mouthpieces in Figure 1, or Figures 3a and 3b, may include multiple material bodies. Mouthpieces 2 and 2' may have cavities between the material bodies.
[0268] In some examples, the mouthpieces 2, 2' downstream of the aerosol-generating composition 3 may comprise a roll of paper, for example, a first plug wrap 7 or a second plug wrap 9, or a tip paper 5, the roll of paper containing an aerosol modifier or other sensory material as described herein. The aerosol modifier may be placed on the inward or outward surface of the mouthpiece roll of paper. For example, the aerosol modifier or other sensory material may be provided on the area of the roll of paper that comes into contact with the consumer's lips during use, such as the outward surface of the tip paper 5. By placing the aerosol modifier or other sensory material on the outward surface of the mouthpiece roll of paper, the aerosol modifier or other sensory material can be transmitted to the consumer's lips during use. The transmission of the aerosol modifier or other sensory material to the consumer's lips during use of the article may modify the sensory properties (e.g., taste) of the aerosol produced by the aerosol-generating composition 3, or otherwise provide the consumer with an alternative sensory experience. For example, an aerosol modifier or other sensation material can impart a fragrance to the aerosol produced by the aerosol generating composition 3. The aerosol modifier or other sensation material may be at least partially water-soluble so that it is transmitted to the user by the consumer's saliva. The aerosol modifier or other sensation material may be volatile due to the heat generated by the aerosol supply system. This facilitates the transfer of the aerosol modifier to the aerosol produced by the aerosol generating composition 3. Suitable sensation materials may include the fragrances described herein, sucralose, or cooling agents such as menthol.
