Preferred thermal agents are, but are not limited to, vanillyl ethyl ether, and preferred cooling agents are, but are not limited to, eucalyptol and WS-3.

[0032] Aerosol-generating materials are materials that can generate aerosols when excited, for example, by heating, irradiation, or some other method. Aerosol-generating materials may be in the form of solids, liquids, or gels, which may or may not contain active substances and / or flavorings. In some embodiments, aerosol-generating materials may include "amorphous solids," which are also referred to separately as "monolithic solids" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. Amorphous solids are solid materials that hold fluids, such as liquids, within themselves. In some embodiments, aerosol-generating materials may contain about 50 wt%, 60 wt%, or 70 wt% amorphous solids to about 90 wt%, 95 wt%, or 100 wt% amorphous solids.

[0033] The aerosol generating material may contain one or more active substances and / or flavorings, one or more aerosol forming materials, and one or more other functional materials if necessary.

[0034] The aerosol-forming agent may contain one or more components capable of forming an aerosol. In some embodiments, the aerosol-forming agent may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, a mixture of diacetins, benzyl benzoate, benzylphenyl acetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. In other embodiments, the aerosol-forming agent may contain one or more polyhydric alcohols such as 1,3-butanediol, esters of polyhydric alcohols such as glycerol mono, di, or triacetate, and / or aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanediate and dimethyl tetradecanediate.

[0035] One or more functional ingredients may include one or more of the following: pH regulators, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0036] The forming material may be on or within the support to form the substrate. The support may be, for example, paper, cardboard, thick paper, recycled material, plastic material, ceramic material, composite material, glass, metal, or metal alloy. In some embodiments, the support includes a susceptor. In some embodiments, the susceptor is embedded in the material. In some other embodiments, the susceptor is on one or both sides of the material.

[0037] Consumables are articles containing or comprising aerosol generating material, which is intended to be consumed by the user, in whole or in part, during use. Consumables may also include one or more other components, such as an aerosol generating material storage area, an aerosol generating material transport member, an aerosol generating area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which radiates heat to cause the aerosol generating material to generate aerosols during use. The heater may include, for example, a combustion system material, an electrically conductive material, or a susceptor.

[0038] A susceptor is a material that can be heated by the intrusion of a fluctuating magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material, and may be configured to induce heating of the heating material by the intrusion of a fluctuating magnetic field. The heating material may be a conductive material, and may be configured to induce magnetic hysteresis heating of the heating material by the intrusion of a fluctuating magnetic field. The susceptor may be based on both conductivity and magnetism, thereby enabling the heating material to be heated by both heating mechanisms. In this specification, a device configured to generate a fluctuating magnetic field is referred to as a magnetic field generator.

[0039] Aerosol modifiers are typically located downstream of an aerosol generation region and are configured to modify the generated aerosol by altering, for example, the taste, flavor, acidity, or other characteristics of the aerosol. The aerosol modifier may be contained within an aerosol modifier release member that is operable to selectively release the aerosol modifier.

[0040] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of the following: a flavoring agent, a coloring agent, water, and a carbon adsorbent. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be a powder, a thread, or granules. The aerosol modifier does not need to contain a filter material.

[0041] An aerosol generator is a device configured to generate an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to expose the aerosol generating material to thermal energy and release one or more volatile substances from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from an aerosol generating material without heating. For example, the aerosol generator may be configured to expose the aerosol generating material to one or more of the following: vibration, high pressure, or electrostatic energy.

[0042] The aerosol generating material may be a carrier on which an amorphous solid is provided. The carrier functions as a support on which an amorphous solid layer is formed to facilitate manufacturing. The amorphous solid layer of the carrier may be provided with tensile strength to facilitate handling.

[0043] The mouthpiece of the article may preferably include an amorphous solid material in the form of a collection of sheets made of amorphous solid material.

[0044] This invention provides a mouthpiece containing an amorphous solid material. By incorporating an amorphous solid material into the mouthpiece, a remarkable discovery was made: it possesses desirable flavor characteristics, resulting in a good aerosol at a lower temperature, thereby improving the user's senses.

[0045] In this case, the amorphous solid material is a sheet that has been assembled, wound, or coiled. In some cases, the sheet may be incorporated into a sheet-shaped mouthpiece. In another example, the sheet may be cut and incorporated into the mouthpiece.

[0046] Aerosol generating material containing amorphous solids: 30 g / m² 2 ~120g / m 2 It may have any suitable surface density, such as 80-120 g / m². In some cases, the sheet may have a density of 80-120 g / m². 2 , or approximately 70-110 g / m 2 Or especially about 90-110 g / m 2Alternatively, preferably about 100 g / m 2 It has a mass per unit area.

[0047] In some cases, a sheet-like amorphous solid may have a tensile strength of approximately 200 N / m to approximately 900 N / m. In some cases, such as when the amorphous solid does not contain fillers, the amorphous solid may have a tensile strength of 200 N / m to 400 N / m, or 200 N / m to 300 N / m, or approximately 250 N / m.

[0048] In some examples, such as when the amorphous solid contains a filler, the amorphous solid may have a tensile strength of 600 N / m to 900 N / m, 700 N / m to 900 N / m, or about 800 N / m. Such tensile strengths are particularly suitable for embodiments in which the amorphous solid material is contained in an aerosol-generating article / assembly in the form of rolled sheets, preferably tubes.

[0049] In some cases, the carrier layer may be substantially or completely impermeable to gases and / or aerosols. This prevents aerosols or gases from passing through the carrier, controlling the flow and ensuring a good supply to the user.

[0050] The carrier may be any suitable material available for supporting an amorphous solid. In some cases, the carrier may be formed from a material selected from metal foil, paper, carbon paper, oil-resistant paper, ceramics, carbon allotropes such as graphite and graphene, plastics, cardboard, wood, or combinations thereof. In some cases, the carrier may contain or consist of tobacco material, such as a sheet of recycled cigarette. In some cases, the carrier may be formed from a material selected from metal foil, paper, cardboard, wood, or combinations thereof. In some cases, the carrier may be a laminated structure including layers made of materials selected from the above examples. In some cases, the carrier may function as a flavor carrier. For example, the carrier may be impregnated with flavorings or tobacco extracts.

[0051] In some cases, the surface of the carrier in contact with the amorphous solid may be porous. For example, the carrier may include paper. The inventors have found that porous carriers such as paper are particularly suitable for the present invention, and that the porous (paper) layer in contact with the solid layer and adheres firmly. The amorphous solid is formed by drying a gel, and is not limited to any theory, but it is thought that the slurry in which the gel is formed is partially impregnated into a porous carrier (e.g., paper) so that the carrier partially bonds to the gel when the gel hardens and crosslinks are formed. This creates a strong bond between the gel and the carrier (and between the dried gel and the carrier).

[0052] In addition, surface roughness contributes to the strength of adhesion between the amorphous solid and the carrier. The inventors stated that the roughness of the paper (of the surface in contact with the carrier) is in the range of 50 to 1000 Beck seconds, preferably 50 to 150 Beck seconds, and more preferably 100 Beck seconds (measured at air pressure intervals of 50.66 to 48.00 kPa). (A Beck smoothness tester is a device used to measure the smoothness of the paper surface at which air leaks between a smooth glass surface and a paper sample at a specific pressure, and the time (seconds) at which a predetermined amount of air seeps between these surfaces is called "Beck smoothness.") In another case, lamination of paper and oil-resistant paper has been found to be particularly useful in the present invention. The paper layer is in contact with the amorphous solid, and the adhesive amorphous solid does not readily adhere to the oil-resistant paper carrier base.

[0053] Depending on the case, the carrier may be approximately 0.010 mm to 2.0 mm, preferably approximately 0.015 mm, 0.02 mm, 0.05 mm, or 0.1 mm to 1.5 mm, 1.0 mm. It has a thickness of 0.5 mm.

[0054] In some cases, the amorphous solid layer is approximately 0.015 mm to approximately 1.5 mm thick, preferably approximately 0.0 It has a thickness of 5 mm to approximately 1.5 mm or 0.05 mm to approximately 1.0 mm. Preferably, the thickness The thickness may range from approximately 0.1 mm or 0.15 mm to approximately 1 mm, 0.5 mm, or 0.3 mm. The amorphous solid may consist of two or more layers, and the thickness described herein refers to the total thickness of these layers.

[0055] The thicknesses specified herein are the average thickness of the material. In some cases, the thickness of amorphous solids may vary by 25%, 20%, 15%, 10%, 5%, or 1%.

[0056] In some cases, the amorphous solid may contain 1 to 60 wt% of a gelling agent, the weight of which is calculated on a dry weight basis.

[0057] Preferably, the amorphous solid may contain about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt%, or 27 wt% of the gelling agent (all calculated on a dry weight basis). For example, the amorphous solid may contain 1 to 50 wt%, 5 to 40 wt%, 10 to 30 wt%, or 15 to 27 wt% of the gelling agent.

[0058] The gelling agent may include one or more compounds selected from cellulosic gelling agents, non-cellulosic gelling agents, guar gum, acacia gum, and mixtures thereof.

[0059] In some embodiments, the cellulosic gelling agent consists of hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC), methylcellulose, ethylcellulose, cellulose acetate (CA), cellulose acetate butyrate (CAB), cellulose acetate propionate (CAP), and combinations thereof. Selected from the group.

[0060] In some embodiments, the gelling agent comprises (or is) one or more of hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose (HPMC), carboxymethylcellulose, guar gum, or acacia gum.

[0061] In some embodiments, the gelling agent includes (or is) one or more non-cellulose gelling agents, including agar, xanthan gum, gum arabic, guar gum, carob gum, pectin, carrageenan, starch, alginate, and combinations thereof. In preferred embodiments, the non-cellulose gelling agent is alginate or agar.

[0062] In some embodiments, the gelling agent comprises a hydrophilic colloid. In some embodiments, the gelling agent comprises one or more compounds selected from alginates, pectins, starches (and derivatives), celluloses (and derivatives), rubber, silica or silicone compounds, clay, polyvinyl alcohol, and combinations thereof. For example, in some embodiments, the gelling agent comprises one or more of alginates, pectins, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, acacia gum, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the gelling agent comprises alginates and / or pectins and may be mixed with a curing agent (such as a calcium source) during the formation of an amorphous solid. In some cases, the amorphous solid may comprise calcium-crosslinked alginates and / or calcium-crosslinked pectins.

[0063] In some embodiments, the gelling agent comprises an alginate, which is present in the amorphous solid in an amount of 10-30 wt% (calculated on a dry weight basis). In some embodiments, the alginate is the only gelling agent present in the amorphous solid. In other embodiments, the gelling agent comprises an alginate and at least one additional gelling agent, such as pectin.

[0064] In some embodiments, the amorphous solid may contain a gelling agent including carrageenan.

[0065] Preferably, the amorphous solid may contain about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, or 10% to about 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt%, or 25 wt% (all calculated on a dry weight basis) of an aerosol-generating agent. The aerosol-generating agent may act as a plasticizer. For example, the amorphous solid may contain 0.5 The aerosol generator may be present in amounts of ~40 wt%, 3~35 wt%, or 10~25 wt%. In some cases, the aerosol generator comprises one or more compounds selected from erythritol, propylene glycol, glycerol, triacetin, sorbitol, and xylitol. In some cases, the aerosol generator comprises glycerol, is substantially composed of glycerol, or is composed of glycerol. The inventors have confirmed that if the plasticizer content is too high, the amorphous solid will absorb water and become a material that does not produce a suitable consumption experience during use. The inventors have confirmed that if the plasticizer content is too low, the amorphous solid will become brittle and easily broken. The amounts of plasticizer specified herein provide flexibility to the amorphous solid, allowing the amorphous solid sheet to be wound onto bobbins useful for manufacturing aerosol-generating products.

[0066] Amorphous solids may contain flavorings. In some cases, amorphous solids may contain flavorings of about 80 wt%, 70 wt%, 60 wt%, 55 wt%, 50 wt%, or 45 wt% or less. In some cases, amorphous solids may contain at least about 0.1 wt%, 1 wt%, 10 wt%, 20 wt%, 30 wt%, 35 wt%, or 40 wt% of flavorings (all calculated on a dry weight basis). For example, amorphous solids may contain 1-80 wt%, 10-80 wt%, 20-70 wt%, 30-60 wt%, 35-55 wt%, or 30-45 wt% of flavorings. In some cases, the flavorings may include menthol, be substantially composed of menthol, or consist of menthol.

[0067] The amorphous solid may contain a coloring agent. The appearance of the amorphous solid may be altered by adding a coloring agent. The presence of a coloring agent in the amorphous solid may improve the appearance of the amorphous solid and the aerosol generating material. By adding a coloring agent to the amorphous solid, the color of the amorphous solid may be matched to other components of the aerosol generating material or other components of the article containing the amorphous solid.

[0068] Various colorants may be used depending on the desired color of the amorphous solid. The color of the amorphous solid may be, for example, white, green, red, purple, blue, or black. Other colors are also conceivable. Natural or synthetic colorants, such as natural or synthetic dyes, food-grade colorants, and pharmaceutical-grade colorants, may be used. In certain embodiments, the colorant is caramel, which gives the amorphous solid a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components in the aerosol generating material containing the amorphous solid (such as tobacco material). In some embodiments, the addition of a colorant to the amorphous solid makes it visually distinguishable from other components of the aerosol generating material.

[0069] The coloring agent may be incorporated during the formation of the amorphous solid (for example, during the formation of a slurry containing the material that forms the amorphous solid), or it may be applied to the amorphous solid after it has been formed. (For example, by spraying onto an amorphous solid.)

[0070] In some cases, the amorphous solid may contain an emulsifier obtained by emulsifying the molten flavoring during manufacturing. For example, the amorphous solid may contain about 5 wt% to about 15 wt%, preferably about 10 wt% (calculated on a dry weight basis) of emulsifier. The emulsifier may also contain acacia gum.

[0071] In some embodiments, the amorphous solid is a hydrogel containing less than about 20 wt% water on a wet weight basis. In some cases, the hydrogel may contain less than about 15 wt%, 12 wt%, or 10 wt% water on a wet weight basis. In some cases, the hydrogel may contain at least about 1 wt%, 2 wt%, or at least about 5 wt% water.

[0072] The amorphous solid may contain an acid. The acid may be an organic acid. In some of these embodiments, the acid may be at least one of a monobasic acid, a dibasic acid, and a tribasic acid.

[0075] In certain embodiments, the amorphous solid comprises a gelling agent including a cellulose-based gelling agent and / or a non-cellulose-based gelling agent, an active substance, and an acid.

[0076] In some embodiments, the amorphous solid additionally contains an active substance. For example, the amorphous solid may optionally contain additional tobacco material and / or nicotine. In some cases, the amorphous solid may contain 5 to 60 wt% (calculated on a dry weight basis) of tobacco material and / or nicotine. In some cases, the amorphous solid may contain about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (calculated on a dry weight basis) of an active substance. In some cases, amorphous solids may 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 on a dry weight basis) of tobacco material. For example, amorphous solids may contain 10-50 wt%, 15-40 wt%, or 20-35 wt% of tobacco material. In some cases, amorphous solids may contain approximately 1 wt%, 2 wt%, 3 wt%, or 4 wt% to approximately 20 wt%, 18 wt%, 15 wt%, or 12 wt% of nicotine (calculated on a dry weight basis). For example, amorphous solids may contain 1-20 wt%, 2-18 wt%, or 3-12 wt% of nicotine.

[0077] In some cases, the amorphous solid may contain active substances such as tobacco extract. In some cases, the amorphous solid may contain 5-60 wt% (calculated on a dry weight basis) of tobacco extract. In some cases, the amorphous solid may contain approximately 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to approximately 60 wt%, 50 wt%, 45 wt%, or 40 wt%, 35 wt%, or 30 wt% (calculated on a dry weight basis) of tobacco extract. For example, the amorphous solid may contain 10-50 wt%, 14-40 wt%, or 20-35 wt% of tobacco extract. Tobacco extracts may contain nicotine at concentrations of 1 wt%, 1.5 wt%, 2 wt%, or 2.5 wt% to approximately 6 wt%, 5 wt%, 4.5 wt%, or 4 wt% (calculated on a dry weight basis) in amorphous solid form. In some cases, amorphous solid nicotine other than that obtained from the tobacco extract may not be present.

[0078] In some embodiments, the amorphous solid does not contain tobacco material but contains nicotine. In some such cases, the amorphous solid may contain about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% of nicotine (calculated on a dry weight basis). For example, the amorphous solid may contain 1 to 20 wt%, 2 to 18 wt%, or 3 to 12 wt% of nicotine.

[0079] In some cases, the total content of active ingredients and flavorings may be at least approximately 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active ingredients and flavorings may be less than approximately 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all calculated on a dry weight basis).

[0080] In some cases, the total content of tobacco material, nicotine, and flavorings may be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active ingredients and / or flavorings may be less than about 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all calculated on a dry weight basis).

[0081] The amorphous solid may be prepared from a gel, and the gel may contain an additional 0.1 to 50 wt% of a solvent. However, the inventors have confirmed that including a solvent in which the flavoring is soluble reduces the stability of the gel, causing the flavoring to crystallize and leach out of the gel. Therefore, in some cases, the gel does not contain a solvent in which the flavoring is soluble.

[0082] In some embodiments, the amorphous solid is included in a filler amount of less than 60 wt%, for example, 1 wt% to 60 wt%, 5 wt% to 50 wt%, 5 wt% to 30 wt%, or 10 wt% to 20 wt%.

[0083] In other embodiments, the amorphous solid may be less than 20 wt%, preferably less than 10 wt% or less than 5 wt% of filler. In some cases, the amorphous solid may be less than 1 wt% of filler, and in some cases, no filler may be present.

[0084] The filler may contain, if present, one or more suitable inorganic adsorbents such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and molecular sieves. The filler may also contain one or more organic fillers such as wood pulp, cellulose, and cellulose derivatives. In some cases, the amorphous solid contains less than 1 wt% of filler, and in some cases, it contains no filler. In particular, in some cases, the amorphous solid contains calcium carbonate such as chalk.

[0085] In certain embodiments involving a filler, the filler is fibrous. For example, the filler may be a fibrous filler such as wood pulp, hemp fiber, cellulose, or cellulose derivatives. While we do not wish to be bound by any theory, it has been confirmed that incorporating a fibrous filler into an amorphous solid increases the tensile strength of the material. This is particularly advantageous because the increased tensile strength makes it less likely for defects to be introduced into the amorphous solid during manufacturing.

[0086] In some embodiments, the amorphous solid does not contain tobacco fibers. In certain embodiments, the amorphous solid does not contain fibrous material.

[0087] In some embodiments, the aerosol generating material does not contain tobacco fibers. In certain embodiments, the aerosol generating material does not contain fibrous material.

[0088] In some cases, the amorphous solid consists substantially of a gelling agent, an aerosol generator, water, and selectively flavorings and / or tobacco materials and / or a nicotine source.

[0089] In some cases, the amorphous solid consists substantially of a gelling agent, water, an aerosol generator, and selectively flavorings and / or active substances.

[0090] Induction heating is the process of heating a conductive object by allowing a fluctuating magnetic field to penetrate it. This process is explained by Faraday's law of electromagnetic induction and Ohm's law. An induction heater may consist of an electromagnet and a device for passing a fluctuating current, such as alternating current, through the electromagnet. When the object to be heated and the electromagnet are positioned in a suitable relative position such that the fluctuating magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated within the object. This object has resistance to the flow of electric current. Therefore, when such eddy currents are generated within the object, they flow against the object's electrical resistance, thereby heating the object. This process is called Joule heating, Ohm heating, or resistance heating. An object that can be inductively heated is known as a susceptor.

[0091] In one embodiment, the susceptor is in the form of a closed circuit. It has been found that when the susceptor is in the form of a closed circuit, the magnetic coupling between the susceptor and the electromagnet during use is strengthened, resulting in increased or improved Joule heating.

[0092] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by the penetration of a fluctuating magnetic field into the object. Magnetic materials 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 along the magnetic field. Therefore, when a fluctuating magnetic field, such as that generated by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes in accordance with the applied fluctuating magnetic field. This reorientation of magnetic dipoles generates heat within the magnetic material.

[0093] When an object possesses both conductivity and magnetism, introducing a fluctuating magnetic field into it can induce both Joule heating and magnetic hysteresis heating. Furthermore, using magnetic materials can strengthen the fluctuating magnetic field, thereby intensifying the Joule heating.

[0094] In each of the above processes, heat is generated within the object itself rather than by heat conduction from an external heat source, thus enabling a rapid temperature rise within the object and a more uniform heat distribution. This can be achieved, in particular, by appropriately selecting the material and geometry of the object, and by appropriately selecting the magnitude and direction of the fluctuating magnetic field relative to that object. Furthermore, in induction heating and magnetic hysteresis heating, there is no need to provide a physical connection between the source of the fluctuating magnetic field and the object, thus increasing design flexibility and controllability of the heating profile, while also reducing costs.

[0095] For example, items such as rod-shaped articles are often named according to their length as follows: "Standard" (usually 68-75mm, e.g., in the range of approximately 68mm-72mm), "Short" or "Mini" (68mm or less), "King Size" (usually 75-91mm, e.g., in the range of approximately 79mm-88mm), "Long" or "Super King" (usually 91-105mm, e.g., in the range of approximately 94mm-101mm), and "Extra Long" (usually in the range of approximately 110mm-121mm).

[0096] They are also named according to the circumference of the cigarette as follows: "Standard" (approximately 23-25mm), "Wide" (over 25mm), "Slim" (approximately 22-23mm), "Demi-Slim" (approximately 19-22mm), "Super Slim" (approximately 16-19mm), and "Micro Slim" (less than approximately 16mm).

[0097] Therefore, a king-size ultra-slim cigarette, for example, has a length of approximately 83 mm and a circumference of approximately 17 mm.

[0098] Each format may be provided with mouthpieces of different lengths. The length of the mouthpieces will be approximately 30mm to 50mm. Chipping paper connects the mouthpiece to the aerosol generating material, and is usually longer than the mouthpiece, for example, 3 to 10mm in length, so that the chipping paper covers the mouthpiece and overlaps with the aerosol generating material in the form of a rod made of a base material, and connects the mouthpiece to the rod.

[0099] The articles, aerosol generators, and mouthpieces described herein may be manufactured in any of the above formats, but are not limited to these.

[0100] As used herein, the terms “upstream” and “downstream” are relative terms defined with respect to the direction of the mainstream smoke aerosol generating material drawn through the article or device during use.

[0101] The filamentous tow materials described herein may include cellulose acetate fiber tow. The filamentous tow materials may be formed using other materials used to form fibers, such as polyvinyl alcohol (PVOH), polylactic acid (PLA), polycaprolactone (PCL), poly(1,4-butanediol succinate) (PBS), poly(butylene adipate-co-terephthalate) (PBAT), starch-based materials, paper, aliphatic polyester materials, and polysaccharide polymers or combinations thereof. The filamentous tow material may be plasticized with a plasticizer suitable for filter materials, such as triacetin, or may not be plasticized, if the filter material is cellulose acetate tow. The tow may have other cross-sections, such as "Y" or "X" shaped, single filament fineness of 2.5 to 15, e.g., denier values ​​of fibers with single filament fineness of 8.0 to 11.0, and denier values ​​of 5,000 to 50,000, e.g., For example, any suitable specifications can be used, such as fibers with a total fineness value of 10,000 to 40,000.

[0102] In this specification, the term “tobacco material” means any material including tobacco or its derivatives or substitutes. The term “tobacco material” may include one or more of tobacco, tobacco derivatives, expanded tobacco, re-combined tobacco, or tobacco substitutes. Tobacco material may include one or more of powdered tobacco, tobacco fibers, loose tobacco, extruded tobacco, tobacco leaflets, re-combined tobacco, and / or tobacco extracts.

[0103] In this specification, the same reference numeral is used in the drawings to indicate equivalent features, articles, or components.

[0104] Figure 1 is a side cross-sectional view of article 1 used in a non-combustible aerosol supply device. As shown in Figure 1, the article includes a mouthpiece 2 having an upstream end 2a and a downstream end 2b. The mouthpiece 2 includes a material body 6 comprising a sheet made of amorphous solid material. In this example, the amorphous solid material is assembled and wound around a first plug wrapper 7 to form a substantially cylindrical material body 6. In this example, the material body 6 is formed from an assembled sheet of a single amorphous solid sheet material. However, in another embodiment, the sheet of amorphous solid material may be cut into strips before being assembled to form the material body 6.

[0105] In the embodiment shown in Figure 1, the article includes a mouthpiece 2 and further includes an aerosol generating material 3 connected to the mouthpiece 2, which in this example is a cylindrical rod made of tobacco material. The upstream end 2a of the mouthpiece is positioned adjacent to the aerosol generating material, and the downstream end 2b of the mouthpiece 2 is positioned distal to the rod of the aerosol generating material 3.

[0106] This invention has discovered that providing a mouthpiece with a body made of amorphous solid material has the advantage of providing a cooling effect to the aerosol as it is drawn through the mouthpiece during use. While we do not wish to be bound by any theory, it is presumed that the heat transferred from the aerosol to the amorphous solid material as the aerosol passes through the material body 6 aerosolizes the components of the amorphous solid material, resulting in a cooling effect on the aerosol, and, advantageously, alters the flavor of the aerosol as it passes through the mouthpiece as needed. This configuration mitigates the conventional problem of smoking products where the aerosol becomes too hot when it reaches the consumer's lips, and also provides a means to add additional flavor to the aerosol without complicating the manufacturing process.

[0107] In this example, the length of the amorphous solid material 6 is 40 mm.

[0108] The body may be formed using methods known to those skilled in the art for manufacturing paper filters for smoking products. In this example, the amorphous solid material body 6 is formed from a single assembled sheet of amorphous solid material. In another embodiment, the material body 6 may be formed from two or more sheets of amorphous solid material or from a single sheet material that is cut into pieces before being assembled to form the body. In this case, the amorphous solid material consists of a single layer and is not laminated to a carrier material. In yet another embodiment, the amorphous solid material may be laminated to a carrier material such as paper or foil, and the laminated amorphous solid material may be used to form the body by any of the methods described herein.

[0109] In this case, the thickness of the amorphous solid material is 0.09 mm. In another embodiment, the amorphous solid material may have any suitable thickness described herein. Preferably, the thickness of the amorphous solid material is 0.05 mm to 0.2 mm. Preferably, in any of the embodiments described herein, the thickness of the amorphous solid layer is about 50 μm to about 200 μm or about 50 μm to about 100 μm or about 60 μm to about 90 μm, preferably about 77 μm.

[0110] The density of the material body 6 is determined by dividing the total weight of the material body 6 by the total volume of the material body 6, and the total volume can be calculated by means of appropriate measurement of the material body 6, for example using a vernier caliper. Appropriate dimensions may be measured using a microscope if necessary. In this case, the density of the material body is 0.51×10 -3 g / mm 3 . In other embodiments, the density of the material body is 0.1×10 -3 g / mm 3 ~1×10 -3 g / mm 3 .

[0111] The material body 6 is wrapped in a first plug wrapper 7. Preferably, the first plug wrapper 7 has a basis weight of less than 50 gsm, more preferably from about 20 gsm to about 40 gsm. Preferably, the first plug wrapper 7 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. Preferably, the first plug wrapper 7 is a non-porous plug wrapper having an air permeability of, for example, less than 100 Coresta units, such as less than 50 Coresta units. However, in other embodiments, the first plug wrapper 7 may be a porous plug wrapper having an air permeability of, for example, more than 200 Coresta units.

[0112] Figure 2 is a side cross-sectional view of an article 1' including a mouthpiece 2' for use in a non-combustion aerosol supply device. The article 1' comprises a material body 6 similar to that described with reference to Figure 1, except that the length of the material body 6 is 10 mm. In addition to the material body 6, the mouthpiece 2' comprises a hollow tubular member 8 and a fibrous material body 4. In the embodiment shown in Figure 2, the article 1' further comprises a rod 3 made of an aerosol-generating material connected to an upstream end 2' of the mouthpiece 2' opposite a downstream end 2' of the mouthpiece 2'.

[0113] Preferably, the length of the material body 6 is less than about 15 mm. More preferably, the length of the material body 6 is less than about 10 mm. Further or alternatively, the length of the material body 6 is at least about 5 mm. Preferably, the length of the material body 6 is at least about 6 mm. In some preferred embodiments, the length of the 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 the material body 6 is 10 mm.

[0114] The pressure drop or pressure difference (also called suction resistance) in the mouthpiece, for example, the portion of article 1 downstream of the aerosol generating material 3, is preferably less than about 40 mmH2O. Such a pressure drop is known to allow sufficient aerosol, including flavor compounds, to travel to the consumer through the mouthpiece 2. More preferably, the pressure drop in the mouthpiece 2 is less than about 32 mmH2O. In some embodiments, aerosol production has been particularly improved by using a mouthpiece 2 with a pressure drop of less than 31 mmH2O, e.g., about 29 mmH2O, about 28 mmH2O, or about 27.5 mmH2O. Separately or in addition to this, the mouthpiece pressure drop is at least 10 mmH2O, preferably at least 15 mmH2O, and more preferably at least 20 mmH2O. In some embodiments, the mouthpiece pressure drop may be about 15 mmH2O to 40 mmH2O. These values ​​allow the mouthpiece 2 to slow down the aerosol as it passes through the mouthpiece 2, thereby giving the aerosol temperature time to decrease before it reaches the downstream end 2b of the mouthpiece 2.

[0115] The pressure drop or pressure difference of the material is preferably 0.01 mmH2O to 100 mmH2O. In some embodiments, the pressure drop of the material is less than about 50 mmH2O, less than about 45 mmH2O, or less than about 30 mmH2O.

[0116] In this example, material 6 is located downstream of and in contact with a hollow tubular member 8, also known as a cooling member. The hollow tubular member 8 is formed from multiple layers of paper that are wound parallel to each other and have joined seams. In this example, the first and second layers of paper are used for a double tube, but in other examples, three, four or more layers may be used to form a triple, quadruple, or more doubled tube. Other structures, such as spirally wound paper layers, cardboard tubes, tubes formed using a condensate die process, molded or extruded plastic tubes, or similar, can also be used.

[0117] The hollow tubular member 8 may be formed using a rigid plug wrapper and / or chipping paper as the third plug wrapper 11 and / or chipping paper 5, which will be described in detail below, meaning that a separate tubular member is not required. The rigid plug wrapper and / or chipping paper is manufactured to have sufficient rigidity to withstand the axial compressive forces and bending moments that will occur during manufacturing and in use of the article 1'. For example, the rigid plug wrapper and / or chipping paper may have a basis weight of 70 gsm to 120 gsm, more preferably 80 gsm to 110 gsm. Further or separately, the rigid plug wrapper and / or chipping paper may have a thickness of 80 μm to 200 μm, more preferably 100 μm to 160 μm or 120 μm to 150 μm. It is desirable to have values ​​in these ranges in both the third plug wrapper 11 and the chipping paper 5 to achieve an acceptable overall level of rigidity for the hollow tubular member 8.

[0118] The hollow tubular member 8 has dimensions of at least about 100 μm and about 1.5 mm or less, preferably 100 μm to 1 mm and more preferably 150 μm or less, as measured using, for example, a caliper. The wall thickness is preferably 500 μm or about 300 μm. In this example, the hollow tubular member 8 has a wall thickness of about 290 μm.

[0119] Preferably, the length of the hollow tubular member 8 is less than about 50 mm. More preferably, the length of the hollow tubular member 8 is less than about 40 mm. Even more preferably, the length of the hollow tubular member 8 is less than about 30 mm. Further or alternatively, the length of the hollow tubular member 8 is preferably at least about 10 mm. Preferably, the length of the hollow tubular member 8 is at least about 15 mm. In some preferred embodiments, the length of the hollow tubular member 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 hollow tubular member 8 is 25 mm.

[0120] The hollow tubular member 8 is positioned around the mouthpiece 2, defining a void within the mouthpiece, which acts as a cooling segment. The void provides a chamber through which heated volatile components generated by the aerosol generating material 3 flow. The hollow tubular member 8 is hollow to provide a chamber for aerosol deposition, yet it is rigid enough to withstand axial compressive forces and bending movements that may occur during manufacturing and while the article 1' is in use. The hollow tubular member 8 physically moves between the aerosol generating material 3 and the material body 6. The physical movement by the hollow tubular member 8 provides a temperature gradient along the length of the hollow tubular member 8.

[0121] The hollow tubular member 8 can be configured to provide a temperature difference of at least 40°C between the heated and volatile components entering the first upstream end of the hollow tubular member 8 and the heated and volatile components exiting the second downstream end of the hollow tubular member 8. Preferably, the hollow tubular member 8 is configured to provide a temperature difference of at least 60°C, preferably at least 80°C, and more preferably at least 100°C, between the heated and volatile components entering the first upstream end of the hollow tubular member 8 and the heated and volatile components exiting the second downstream end of the hollow tubular member 8. This temperature difference along the length of the hollow tubular member 8 protects the temperature-sensitive first material body 6 from the high temperature of the aerosol generating material 3 when heated.

[0122] In another embodiment, the hollow tubular member 8 can be replaced with another cooling member, for example, a member made of a material that allows aerosols to pass through longitudinally and also performs a cooling function for the aerosols, such as an amorphous solid material 6.

[0123] In this example, the fibrous material body 4 is located immediately downstream of the material body 6 and in contact with it at the downstream mouthpiece end 2'b of the mouthpiece 2'. The fibrous material body 4 is encased in a second plug wrapper 9, which is the same as the first plug wrapper 7 in this example. The material body 6 and the fibrous material body 4 each define a substantially cylindrical shape and share a common longitudinal axis.

[0124] In this example, the hollow tubular member 8, the main body 6, and the fibrous material body 4 are assembled using a third plug wrapper 11 that is wrapped around all three sections. Preferably, the third plug wrapper 11 has a basis weight of less than 50 gsm, more preferably about 20 gsm to 45 gsm. Preferably, the third plug wrapper 11 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The third plug wrapper 11 is preferably a non-porous plug wrapper 100 having an air permeability of less than cholesta units, for example, less than 50 cholesta units. However, in another embodiment, the third plug wrapper 11 may be a porous plug wrapper having an air permeability of, for example, more than 200 cholesta units.

[0125] In this example, the fibrous material 4 is formed from a filamentous tow. In this example, the tow used for the fibrous material 4 has a single filament fineness (dpf) of 8.4 and a total fineness of 21,000. Alternatively, the tow may have, for example, a single filament fineness (dpf) of 9.5 and a total fineness of 12,000. Alternatively, the tow may have, for example, a single filament fineness (dpf) of 8 and a total fineness of 15,000. In this example, the tow comprises plasticized cellulose acetate tow. The plasticizer used in the tow contains approximately 7% by weight of tow. In this example, the plasticizer is triacetin. In other examples, different materials can also be used to form the fibrous material 4. For example, instead of tow, the fibrous material 4 may be formed from paper, for example, a conventional paper filter used for cigarettes. Alternatively, the fibrous material 4 may be formed from materials other than cellulose acetate, such as polylactic acid (PLA), other materials or similar materials described herein for the filamentous tow. The tow is preferably formed from cellulose acetate. Regardless of whether it is formed from cellulose acetate or other material, the tow preferably has a dpf of at least 5, more preferably at least 6, and even more preferably at least 7. These values ​​of single filament fineness provide a relatively coarse, thick fiber tow with a smaller surface area than a tow with a lower single filament fineness, and as a result, the pressure drop of the resulting mouthpiece 2' is smaller than that of a tow with a lower dpf value. Preferably, to obtain a sufficiently uniform fibrous material 4, the tow has a single filament fineness of 12 d.pf, preferably less than 11 d.pf, and more preferably less than 10 d.pf.

[0126] The total fineness of the tow forming the fibrous material body 4 is preferably up to 30,000, more preferably up to 28,000, and even more preferably up to 25,000. These values ​​of total fineness provide a tow that occupies a small proportion of the cross-sectional area of ​​the mouthpiece 2', resulting in less suction resistance and therefore less pressure drop of the mouthpiece 2' than a tow with a higher total fineness value. For a suitable hardness of the fibrous material body 4, the tow preferably has a total fineness of at least 8,000, and more preferably at least 10,000. Preferably, the single filament fineness is 5 to 12, and the total fineness is 10,000 to 25,000. More preferably, the single filament fineness is 6 to 10, and the total fineness is 11,000 to 22,000. Preferably, the cross-sectional shape of the tow filament is "Y" shaped, but in other embodiments, other shapes such as "X" shaped filaments with the same dpf and total fineness value as provided herein may also be used.

[0127] Preferably, the length of the fibrous material 4 is less than about 15 mm. More preferably, the length of the fibrous material 4 is less than about 10 mm. Further or alternatively, the length of the fibrous material 4 is at least about 5 mm. Preferably, the length of the fibrous material 4 is at least about 6 mm. In some embodiments, the length of the fibrous material 4 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 10 mm, most preferably about 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. In this example, the length of the fibrous material 4 is 10 mm.

[0128] In this example, the aerosol generating material 3 is wrapped in a wrapper 10. The wrapper 10 may be, for example, a paper or a foil wrapper supported on paper. In this example, the wrapper 10 is substantially airtight. In another embodiment, the wrapper 10 has permeability preferably less than 100 cholesta units, more preferably less than 60 cholesta units. It has been found that wrappers with low permeability, e.g. less than 100 cholesta units, more preferably less than 60 cholesta units, result in improved aerosol formation in the aerosol generating material 3. While we do not wish to be bound by any theory, this is presumed to be due to less loss of aerosol compounds through the wrapper 10. The permeability of the wrapper 10 can be measured according to ISO 2965:2009 for measuring air permeability of materials used as cigarette paper, filter plug wrappers and filter bonding paper.

[0129] In this embodiment, the wrapper 10 includes aluminum foil. Aluminum foil has been shown to be particularly effective in enhancing aerosol formation within the aerosol generating material 3. In this example, the aluminum foil has a metal layer with a thickness of approximately 6 μm. In this example, the aluminum foil has a backing. However, in other configurations, the aluminum foil may have other thicknesses, for example, 4 μm to 16 μm. The aluminum foil does not require a backing, but may have a backing made of another material, for example, that helps to provide the foil with adequate tensile strength, or it may not have a backing at all. Metal layers or foils other than aluminum can also be used. The total thickness of the wrapper is preferably 20 μm to 60 μm, more preferably 30 μm to 50 μm, which is a thickness that can provide a wrapper with suitable structural integrity and heat transfer properties. The tension that can be applied to the wrapper before it breaks is greater than 3,000 grams, for example, 3,000 to 10,000 grams or 3,000 to 4,500 grams.

[0130] The ventilation level of the aerosol drawn in through the article is approximately 60%. In another embodiment, the article may have a ventilation level of 50% to 80%, for example, 65% to 75%, of the aerosol drawn in through the article. These levels of ventilation help to slow down the flow of aerosol drawn in through the mouthpiece 2', thereby allowing the aerosol to cool before it reaches the downstream end of the mouthpiece 2'. The ventilation is provided directly within the mouthpiece 2' of the article 1'. In this example, the ventilation is provided within a hollow tubular member 8, which has been found to be particularly beneficial in assisting the aerosol generation process. The ventilation is provided via first and second parallel rows of perforations 12, formed in this case as laser perforations, at positions 17.925 mm and 18.625 mm, respectively, from the downstream mouthpiece end 2' of the mouthpiece 2'. These perforations pass through the chipping paper 5 and the hollow tubular member 8. In another embodiment, ventilation may be provided at other locations on the mouthpiece, for example, within the fibrous material body 4 or the first tubular member 11.

[0131] The aerosol generating material includes an aerosolizable material, also called an aerosol-forming material. The aerosolizable material may be present on a substrate. The substrate may be, for example, paper, cardboard, thick paper, recycled aerosolizable material, plastic material, ceramic material, composite material, glass, metal, or metal alloy.

[0132] In this example, the aerosol-forming material added to the aerosol-generating substrate 3 contains 14% by weight of aerosol-generating material 3. Preferably, the aerosol-forming material contains at least 5% by weight, more preferably at least 10% by weight of aerosol-generating material. Preferably, the aerosol-forming material contains less than 25% by weight, more preferably less than 20%, for example, 10% to 20%, 12% to 18%, or 13% to 16% by weight of aerosol-generating material.

[0133] Preferably, the aerosol generating material 3 is provided as a cylindrical rod made of aerosol generating material. Regardless of the shape of the aerosol generating material, the aerosol generating material has a length of about 10 mm to 100 mm. In some embodiments, the length of the aerosol generating material is preferably in the range of about 25 mm to 50 mm, more preferably in the range of about 30 mm to 45 mm, and even more preferably about 30 mm to 40 mm.

[0134] The volume of the aerosol generating material 3 provided is approximately 200 mm³. 3 ~Approximately 4300mm 3 Preferably about 500 mm 3 ~1500mm 3 , more comfortably approximately 1000mm 3 ~approximately 1300mm 3 They may differ. For example, approximately 1000mm 3 ~approximately 1300mm 3 It has been shown that providing these volumes of aerosol generating material is advantageous in achieving superior aerosols with better visibility and perceptual performance than those achieved with volumes selected from the lower end of that range.

[0135] The mass of the aerosol generating material 3 provided may 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. It has been found that providing an aerosol generating material with a larger mass has the advantage of resulting in better perceptual performance compared to aerosols generated from tobacco material with a smaller mass.

[0136] Preferably, the aerosol generating material 3 is formed from a tobacco material described herein that contains tobacco components.

[0137] In the tobacco materials described herein, the tobacco component includes recycled tobacco. The tobacco component also includes loose tobacco, extruded tobacco, and / or band-cast tobacco.

[0138] The aerosol generating material 3 may include recycled tobacco material having a density of less than approximately 700 milligrams (mg / cc) per cubic centimeter. Such tobacco material has been found to be particularly effective in providing an aerosol generating material that can be heated quickly to release aerosols compared to high-density materials. For example, the inventors tested the heated properties of various aerosol generating materials, such as band-cast recycled tobacco material and recycled paper tobacco material. For each given aerosol generating material, there exists a certain zero heat flow temperature while heat is applied to the material. Below this temperature, the net heat flow becomes endothermic, meaning more heat enters the material than leaves it; above this temperature, the net heat flow becomes exothermic, meaning more heat leaves the material than enters it. Materials with a density of less than 700 mg / cc had a low zero heat flow temperature. Since a significant portion of the heat flow leaving the material is through aerosol formation, having a low zero heat flow temperature has a beneficial effect over the time it takes for the aerosol generating material to first release aerosols. For example, we found that aerosol-generating materials with a density of less than 700 mg / cc had a zero heat flow temperature of less than 164°C compared to materials with a density exceeding 700 mg / cc that had a zero heat flow temperature of more than 164°C.

[0139] The density of the aerosol generating material also affects the rate at which heat is transferred through the material. At lower densities, such as less than 700 mg / cc, the rate at which heat is transferred through the material slows down, thus enabling more sustained aerosol release.

[0140] Preferably, the aerosol generating material 3 comprises recycled tobacco material having a density of less than about 700 mg / cc, such as recycled paper tobacco material. More preferably, the aerosol generating material 3 comprises recycled tobacco material having a density of less than about 600 mg / cc. Separately or in addition, the aerosol generating material 3 preferably comprises recycled tobacco material having a density of at least 350 mg / cc, which is considered to allow a sufficient amount of heat conduction through the material.

[0141] The tobacco material may be supplied in the form of shredded tobacco. The shredded tobacco has a cutting width of at least 15 pieces per inch (5.9 pieces per centimeter, equivalent to a cutting width of about 1.7 mm). Preferably, the shredded tobacco has a cutting width of at least 18 pieces per inch (about 7.1 pieces per centimeter, equivalent to a cutting width of about 1.4 mm), more preferably at least 20 pieces per inch (7.9 pieces per centimeter, equivalent to a cutting width of about 1.27 mm). In one example, the shredded tobacco has a cutting width of 22 pieces per inch (8.7 pieces per centimeter, equivalent to a cutting width of about 1.15 mm). Preferably, the shredded tobacco has a cutting width of at least 40 pieces per inch or less (about 15.7 pieces per centimeter, equivalent to a cutting width of about 0.64 mm). Cutting widths of 0.5 mm to 2.0 mm, for example, 0.6 mm to 1.5 mm or 0.6 mm to 1.7 mm, have been found to result in tobacco material that is preferable in terms of surface area to volume ratio and the overall density and pressure drop of the generated material 3, especially when heated. Shredded tobacco can be formed from a mixture of tobacco material forms, such as a mixture of one or more of recycled tobacco, loose leaf tobacco, extruded tobacco, and band-cast tobacco. Preferably, the tobacco material includes recycled tobacco or a mixture of recycled tobacco and loose leaf tobacco.

[0142] In the tobacco materials described herein, the tobacco material may include filler components. Filler components are generally non-tobacco components, i.e., components that do not contain tobacco-derived components. Filler components may be non-tobacco fibers such as wood fibers or pulp or wheat fibers. Filler components may be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may be non-tobacco cast materials or non-tobacco extruded materials. Filler components may be present in an amount of 0-20% by weight of the tobacco material or 1-10% by weight of the composition. In some embodiments, filler components are not included.

[0143] In the tobacco materials described herein, the tobacco material includes an aerosol-forming agent. In this context, “aerosol-forming agent” is a chemical substance that promotes aerosol generation. The aerosol-forming agent may promote aerosol generation by promoting the initial vaporization of a gas and / or aggregation into inhalable solid and / or liquid aerosols. In some embodiments, the aerosol-forming agent may improve the flavor delivery from the aerosol-generating agent. In general, any suitable aerosol-forming agent or shaping agent may be included in the aerosol-generating agent of the present invention, including those described herein. Other suitable aerosol-forming materials include, but are not limited to, sorbitol, glycerol, polyols such as propylene glycol or glycols such as triethylene glycol, non-polyols such as monohydric alcohols, high-boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate or myristic acid esters including ethyl myristate and isopropyl myristate, and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanediate and dimethyl tetradecanediate. In some embodiments, the aerosol-forming 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. Propylene glycol, if present, may be present in an amount of 0.1-0.3% by weight of the composition.

[0144] The aerosol-forming material may be contained in any component, for example, any component made of tobacco material and / or any filler component. Separately or in addition, the aerosol-forming material may be added separately to the tobacco material. In any case, the total amount of the aerosol-forming material in the tobacco material may be as described herein.

[0145] The tobacco material may contain 10-90% by weight of tobacco leaves, and the aerosol-forming material is supplied in an amount of approximately 10% by weight of the tobacco leaves. It has been found that adding this to the components of the tobacco material, such as recycled tobacco material, in a high weight percentage is advantageous in order to achieve a total amount of aerosol-forming material of 10-20% by weight of the tobacco material.

[0146] The tobacco materials described herein contain nicotine. The nicotine content is 0.5 to 1.75% by weight of the tobacco material, and may be, for example, 0.8 to 1.5% by weight of the tobacco material. Furthermore, or separately, the tobacco material contains 10 to 90% by weight of tobacco leaves having a nicotine content of more than 1.5% by weight of the tobacco leaves. It has been found that using tobacco leaves with a nicotine content of more than 1.5% in combination with a low-nicotine base material such as recycled cigarettes has the advantage of producing a tobacco material that contains an appropriate amount of nicotine but has better perceptual performance than using recycled cigarettes alone. Tobacco leaves, for example, shredded cigarettes, may have a nicotine content of, for example, 1.5% to 5% by weight of the tobacco leaves.

[0147] The tobacco material described herein may contain an aerosol modifier such as any of the flavorings described herein. In one embodiment, the tobacco material contains menthol to form a mentholized article. The tobacco material may contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, and 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, and 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 menthol content can be achieved by using a high percentage of recycled tobacco material, for example, more than 50% by weight of tobacco material. Separately or in addition to this, a high volume of aerosol generating material, such as tobacco material, can be used to achieve, for example, about 500 mm 3 More than, or preferably 1000 mm 3The amount of menthol filling achieved when aerosol generating materials such as ultra-high-quality tobacco materials are used can be increased.

[0148] In the compositions described herein, when amounts are expressed in weight percent, to avoid misunderstanding, this means based on dry weight unless otherwise specified. Therefore, all water present in the tobacco material or any of its components is completely disregarded for the purpose of weight percent measurement. The moisture content of the tobacco materials described herein may vary, for example, from 5 to 15% by weight. The moisture content of the tobacco materials described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The moisture content may be measured by Karl-Fisher analysis, as known to those skilled in the art. On the other hand, to avoid misunderstanding, the aerosol-forming material is glycerin. Even in the case of components in the liquid phase, such as roll or propylene glycol, all components other than water are included in the weight of the tobacco material. However, if an aerosol-forming agent is used in addition to or instead of being added separately to the tobacco material, the aerosol-forming agent is not included in the weight of the tobacco composition or the filler (if any), but is included in the weight of "aerosol-forming agent" in the weight % specified herein. All other components present in the tobacco composition, even if they are non-tobacco-derived (e.g., non-tobacco fibers in the case of recycled cigarettes), are included in the weight of the tobacco component.

[0149] In one embodiment, the tobacco material comprises a tobacco component as defined herein and an aerosol-forming material as defined herein. In another embodiment, the tobacco material consists substantially of a tobacco component as defined herein and an aerosol-forming material as defined herein. In yet another embodiment, the tobacco material consists of a tobacco component as defined herein and an aerosol-forming material as defined herein.

[0150] Recycled tobacco is 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 some embodiments, recycled tobacco is present in an amount of 10% to 80% or 20% to 70% by weight of the tobacco components. In other embodiments, the tobacco components consist substantially of or comprise recycled tobacco. In preferred embodiments, tobacco leaves are present in the tobacco components of the tobacco material in an amount of at least about 10% by weight of the tobacco components. For example, tobacco leaves may be present in an amount of at least 10% by weight of the tobacco components, and the remainder of the tobacco components may include a combination of recycled tobacco, band-cast tobacco or band-cast recycled tobacco and other forms of tobacco such as tobacco pellets.

[0151] Recycled tobacco refers to tobacco material formed by extracting tobacco raw materials with a solvent to obtain a residue containing soluble extracts and fibrous material, and then recombining the extract (usually concentrated and optionally further processed) with fibrous material from the residue (usually after removing impurities from the fibrous material and optionally adding a small amount of non-tobacco fiber) by depositing the extract onto the fibrous material. The recombination process is similar to the papermaking process.

[0152] Recycled cigarettes may be any type of recycled cigarette known in this industry. In certain embodiments, recycled cigarettes are manufactured from raw materials comprising one or more of tobacco strips, tobacco stalks, and whole tobacco leaves. In other embodiments, recycled cigarettes are manufactured from raw materials comprising tobacco strips and / or whole tobacco leaves and tobacco stalks. However, in other embodiments, scraps, fine powder, and chaff may be used separately or in addition to these as raw materials.

[0153] The recycled tobacco used in the tobacco materials described herein may be prepared by methods known to those skilled in the art for the preparation of recycled tobacco.

[0154] In this example, article 1' has a circumference of approximately 21 mm (i.e., the article is in a demi-slim format). In other examples, the article can be provided in any of the formats described herein, having, for example, a circumference of 15 mm to 25 mm. Since the article is heated to release an aerosol, improvements in heating efficiency can be achieved by using an article with a smaller circumference within this range, for example, less than 23 mm. Article circumferences greater than 19 mm have been found to be particularly effective in achieving improved aerosol release by heating while maintaining a suitable product length. Articles with circumferences of 19 mm to 23 mm, more preferably 20 mm to 22 mm, have been found to effectively supply aerosol while achieving efficient heating.

[0155] The outer circumference of the mouthpiece 2' is substantially the same as the outer circumference of the rod 3 of the aerosol generating material, thereby ensuring a smooth connection between these components. In this example, the outer circumference of the mouthpiece 2' is approximately 20.8 mm. Chipping paper 5 is wrapped around the entire length of the mouthpiece 2' and a portion of the rod 3 of the aerosol generating material, and has adhesive on its inner surface to connect the mouthpiece 2' and the rod 3. In this example, the chipping paper 5 extends 5 mm over the rod 3 of the aerosol generating material, but separately extends 3 mm to 10 mm or 4 mm to 6 mm over the rod 3 to ensure a secure attachment between the mouthpiece 2' and the rod 3. The chipping paper 5 may have a larger basis weight than the plug wrapper used for article 1', for example, 40 gsm to 80 gsm, more preferably 50 gsm to 70 gsm, and in this example, 58 gsm. These basis weights have been shown to result in a chipping paper that is sufficiently flexible to wrap article 1 while possessing acceptable tensile strength, and that adheres to itself along the longitudinal seams of the paper. The outer circumference of the chipping paper 5 is approximately 21 mm when wrapped around the mouthpiece 2'.

[0156] Figure 3 is a side cross-sectional view of another article 1''. Article 1'' is substantially the same as article 1'' except that the mouthpiece 2'' includes a second hollow tubular member 13 at the mouthpiece end 2''b instead of the fibrous material body 4.

[0157] The second hollow tubular member 13 is formed from a filamentous tow. This has been found to significantly reduce the temperature of the outer surface of the mouthpiece 2'' at the downstream end 2''b of the mouthpiece that comes into contact with the consumer's lips when using the article 1''. In addition, it has been found that the use of the tubular member 13 also significantly reduces the temperature of the outer surface of the mouthpiece 2'' even upstream of the tubular member 13. While we do not wish to be bound by any theory, this is presumed to be due to the tubular member 13 directing the aerosol closer to the center of the mouthpiece 2'', and thus reducing the transfer of heat from the aerosol to the outer surface of the mouthpiece 2''.

[0158] The "wall thickness" of the second hollow tubular member 13 corresponds to the thickness of the radial wall of the pipe 13. This may be measured in the same way as in the case of the hollow tubular member 8. It is advantageous for the wall thickness to be greater than 0.9 mm, more preferably 1.0 mm or more. Preferably, the wall thickness is substantially constant around the entire perimeter of the wall of the tubular member 11. However, if the wall thickness is not substantially constant, the wall thickness is preferably greater than 0.9 mm, more preferably 1.0 mm or more at any point around the tubular member 11.

[0159] Preferably, the length of the second hollow tubular member 13 is less than about 20 mm. More preferably, the length of the second hollow tubular member 13 is less than about 15 mm. Even more preferably, the length of the second hollow tubular member 13 is less than about 10 mm. Further or as an alternative example, the length of the second hollow tubular member 13 is at least about 5 mm. Preferably, the length of the second hollow tubular member 13 is at least about 6 mm. In some preferred embodiments, the length of the second hollow tubular member 13 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 second hollow tubular member 13 is 6 mm.

[0160] Preferably, the density of the second hollow tubular member 13 is at least about 0.25 grams (g / cc) per cubic centimeter, more preferably at least about 0.3 g / cc. Preferably, the density of the second hollow tubular member 13 is about 0.75 per cubic centimeter. The density is less than a gram (g / cc), more preferably less than 0.6 g / cc. In some embodiments, the density of the second hollow tubular member 13 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 shown to provide a good balance between the good stiffness provided by the high-density material and the low thermal conductivity of the low-density material. For the purposes of this example, the "density" of the second hollow tubular member 13 refers to the density of the filamentous tows forming the member, which may contain some incorporated plasticizer. The density of the second hollow tubular member 13 may be measured in the same manner as described for material 6.

[0161] The filamentous tow forming the second hollow tubular member 13 preferably has a total fineness of less than 45,000, more preferably less than 42,000. It has been found that this total fineness allows for the formation of a tubular member 13 that is not too dense. Preferably, the total fineness is at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filamentous tow forming the second hollow tubular member 13 has a total fineness of 25,000 to 45,000, more preferably 35,000 to 45,000. Preferably, the cross-sectional shape of the filamentous tow is "Y" shaped, but other shapes such as "X" shaped filaments can also be used in other embodiments.

[0162] The filamentous tow forming the second hollow tubular member 13 preferably has a single filament fineness greater than 3. It has been found that this single filament fineness allows for the formation of a hollow tubular member 13 that is not too dense. Preferably, the single filament fineness is at least 4, more preferably at least 5. In a preferred embodiment, the filamentous tow forming the second hollow tubular member 13 has a single filament fineness of 4 to 10, more preferably 4 to 9. In one example, the filamentous tow forming the second hollow tubular member 13 is formed from cellulose acetate and has an 8Y40,000 tow containing 18% plasticizer such as triacetin.

[0163] The second hollow tubular member 13 preferably has an inner diameter of more than 3.0 mm. A smaller inner diameter would cause the aerosol to travel through the mouthpiece 2 to the consumer's mouth at a speed faster than desired, causing the aerosol to become too hot, for example, reaching a temperature of more than 40°C or 45°C. More preferably, the second hollow tubular member 13 has an inner diameter of more than 3.1 mm. More preferably, it has an inner diameter of 3.5 mm or greater than 3.6 mm. In one embodiment, the inner diameter of the second hollow tubular member 13 is about 3.9 mm.

[0164] The second hollow tubular member 13 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) can also be used. More preferably, the tubular member 13 contains 16% to 20% by weight of a plasticizer, for example, about 17% by weight, about 18% by weight, or about 19% by weight of a plasticizer.

[0165] The combination of the aerosol cooling effect of the hollow tubular member 8 and material body 6, and the second hollow tubular member 13, which reduces the temperature of the outer surface of the mouthpiece, results in a lower aerosol temperature and a lower temperature of the outer surface of the article at the mouthpiece end, thus making the user experience more comfortable.

[0166] Figure 4 is a side cross-sectional view of another article 1''''. Article 1'''' and mouthpiece 2'''' are substantially the same as article 1' and mouthpiece 2', except that an amorphous solid material body 6 is provided at the distal end of mouthpiece 2'''' adjacent to and in contact with the aerosol generating material 3, and a hollow tubular member 8 is provided downstream of the material body 6 and is located between the material body 6 at the distal end of the mouthpiece and the fiber section 4 at the mouthpiece end.

[0167] Placing a material body 6 made of an amorphous solid material adjacent to the aerosol generating material results in the material body 6 being exposed to higher heat compared to when it is located downstream of the cooling member. This configuration improves the release of flavor from the amorphous solid material if the amorphous solid material contains a flavoring agent.

[0168] Figure 5a is a side cross-sectional view of another article 1'''' including a capsule-containing mouthpiece 2''''. Figure 5b is a side cross-sectional view of the capsule-containing mouthpiece shown in Figure 5a. Article 1'''' and mouthpiece 2'''' are the same as article 1' and mouthpiece 2', except that mouthpiece 2'''' includes a capsule-containing section 14 in addition to a hollow tubular member 8, a material body 6 made of amorphous solid material, and a fibrous material body 4. The capsule-containing section 14 contains an aerosol modifier provided in the form of a capsule 15 and is surrounded by an oil-resistant plug wrapper 16.

[0169] In other examples, the aerosol modifier may be provided in other forms, such as being injected into a fibrous material body 4 or being provided on a thread, for example, a thread that carries a flavoring agent or other aerosol modifier and may be placed within the fibrous material body 4. The amorphous solid material forming the material body 6 may also contain an aerosol modifier such as a flavoring agent. If the amorphous solid material contains a flavoring agent, the aerosol modifier contained in the capsule 15 may be selected to complement the flavoring agent contained in the amorphous solid material.

[0170] Capsule 15 has a solid, fragile shell surrounding a liquid payload. In this example, one capsule 15 is used. Capsule 15 is completely embedded within a material body that is substantially the same as the fibrous material body 4. In other words, capsule 15 is completely surrounded by the material forming the material body 14. In other examples, multiple destructible capsules, e.g., two, three or more destructible capsules, may be placed within the fibrous material body 14. The length of the material body 14 can be increased to accommodate the required number of capsules. In examples where multiple capsules are used, the individual capsules may be identical to each other, or they may differ in size and / or capsule payload. In other examples, multiple material bodies 14 may be provided, each having one or more capsules.

[0171] The capsule 15 has a core-shell structure. In other words, the capsule 15 may include a shell that encapsulates a liquid, such as a flavoring agent or other substance which may be one of the flavoring agents or aerosol modifiers described herein. The capsule shell can be ruptured by the user, releasing the flavoring agent or other substance into the material body 14. The oil-resistant plug wrapper 16 may include a barrier coating that makes the plug wrapper material substantially impermeable to the liquid payload of the capsule 15. Separately or in addition, a second plug wrapper 9 and / or chipping paper 5 may include a barrier coating that makes the plug wrapper and / or chipping paper material substantially impermeable to the liquid payload of the capsule 15.

[0172] In this example, capsule 15 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 15 may be in the range of approximately 10 mg to 50 mg.

[0173] In this example, the capsule 15 is positioned at the longitudinal center within the material body 14. That is, the capsule 15 is positioned so that its center is 4 mm away from both ends of the material body 14. In other examples, the capsule 15 may be positioned at a location other than the longitudinal center of the material body 14, i.e., closer to the downstream end of the material body 14 than the upstream end, or closer to the upstream end of the material body 14 than the downstream end. The mouthpiece 2'''' is configured such that the capsule 15 and the ventilation hole 12 are longitudinally offset from each other within the mouthpiece 2''''.

[0174] A cross-section of the mouthpiece 2'''' is shown in Figure 5b. Figure 5b shows the capsule 15, the material body 14, the oil-resistant plug wrapper 16, the third plug wrapper 11, and the chipping paper 5. In other examples, the capsule 15 is located at the center of the longitudinal axis (not shown) of the mouthpiece 2''''. The oil-resistant plug wrapper 16, the third plug wrapper 11, and the chipping paper 5 are arranged concentrically around the material body 14.

[0175] The destructible capsule 15 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 control of the release of the aerosol modifier, also known as the aerosol modifier, during use.

[0176] In some cases, the barrier material (also called the encapsulating agent) is fragile. The capsule is crushed or otherwise broken by the user, releasing the aerosol modifier it contains. Typically, the capsule is broken just before heating begins, but the user can choose when to release the aerosol modifier. The term "fragile capsule" refers to a capsule that breaks under pressure to release the core, for example, a shell that can be ruptured by pressure applied by the user's finger when the user wants to release the capsule's core.

[0177] In some cases, the barrier material is heat-resistant. That is, in some cases, the barrier does not rupture but melts or becomes inoperable at the temperature the capsule reaches during the operation of the aerosol supply device. Specifically, the capsule located inside the mouthpiece may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material may be designed to retain the liquid core up to at least about 50°C to 120°C.

[0178] In other cases, the capsule releases the core composition by swelling of the capsule, for example, melting or rupturing the barrier material when heated.

[0179] The total weight of the capsule may 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.

[0180] The total weight of the core formulation may 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.

[0181] The capsule according to the present invention comprises a core and a shell as described above. The capsule may 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 (e.g., about 9.8 N to about 24.5 N). The capsule crushing strength is determined by the material body 1 The force of the capsule being removed from 4 and ruptured when pressed between two flat metal plates can be measured using a gauge. A suitable measuring device is the Sauter FK 50 fall gauge, which has an attachment with a flat head and can be used to crush the capsule against a flat, hard surface having a surface similar to that of the attachment.

[0182] The capsule may be substantially spherical, and at least approximately 0.4 mm, 0.6 mm, 0 The diameter may be 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 approximately 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. It may be full. Specifically, the diameter of the capsule should be approximately 0.4mm to 10.0mm, 0.8mm to 6.0mm, 2.5mm to 5.5mm, or 2.8mm to 3.2mm. The size may be in the range of m. In some cases, the capsule may have a diameter of approximately 3.0 mm. These sizes are particularly suitable for incorporating the capsule into the articles described herein.

[0183] The cross-sectional area of ​​the capsule 15 at its largest cross-sectional region 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' on which the capsule 15 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'''' described herein with a circumference of 21 mm, the material body 14 has an outer circumference of 20.8 mm, and the radius of this member is 3.31 mm, which is 34.43 mm. 2 This corresponds to the cross-sectional area. In this example, the cross-sectional area of ​​the capsule is 20.5% of the cross-sectional area of ​​mouthpiece 2''''. As an alternative example, if the diameter of the capsule is 3.2 mm, its maximum cross-sectional area is 8.04 mm². 2 In this case, the cross-sectional area of ​​the capsule becomes 23.4% of the cross-sectional area of ​​the material body 14. A capsule having a maximum cross-sectional area of ​​less than 28% of the cross-sectional area of ​​the portion of the mouthpiece 2'''' in which the capsule 15 is provided has the advantage that the pressure drop in the mouthpiece 2'''' is reduced compared to a capsule with a larger cross-sectional area, leaving a suitable space around the capsule for the aerosol, and allowing the aerosol to pass through the mouthpiece 2'''' without the material body 14 removing a considerable amount of aerosol in one piece.

[0184] Preferably, the pressure drop or pressure difference (also called suction resistance), measured as open pressure drop (i.e., with the ventilation opening open), decreases to less than 8 mmH2O when the capsule is broken. More preferably, the open pressure drop decreases to less than 6 mmH2O, and more preferably to less than 5 mmH2O. These values ​​are measured as the average obtained from at least 80 articles manufactured with the same design. Such small changes in pressure drop mean that other aspects of the product design, such as setting the correct ventilation level for a given product pressure drop, can be achieved regardless of whether the consumer chooses to break the capsule or not.

[0185] In some embodiments, when the aerosol-forming material 3 is heated in, for example, a non-combustible aerosol supply device described herein to supply an aerosol, the portion of the mouthpiece 2 in which the capsule is located reaches a temperature of 58-70°C while the system is in use to generate the aerosol. As a result of this temperature, the contents of the capsule are sufficiently warmed to promote the volatilization of the capsule contents, such as an aerosol modifier, into the aerosol formed by the system as the aerosol passes through the mouthpiece 2''''. The contents of capsule 15 may be warmed before capsule 15 breaks, for example, so that when capsule 15 breaks, its contents are more easily released into the aerosol passing through the mouthpiece 2''''. Alternatively, the contents of capsule 15 may be warmed to this temperature after capsule 15 has broken, again resulting in the release of more contents into the aerosol. Advantageously, a mouthpiece temperature in the range of 58-70°C is high enough to facilitate the release of the capsule contents, yet low enough that the outer surface of the part of the mouthpiece 2 in which the capsule is located does not reach a temperature that would be uncomfortable for the consumer to touch in order to crush the mouthpiece 2 and rupture the capsule 15.

[0186] The capsule 15 can be broken by an external force applied to the mouthpiece 2'''', for example, by the consumer crushing the mouthpiece 2'''' using their fingers or other mechanism. The portion of the mouthpiece in which the capsule is located, as described above, is positioned to reach a temperature of over 58°C while the aerosol supply system is in use to generate the aerosol. Preferably positioned within the mouthpiece 2'''', the burst strength of the capsule 15 before heating of the aerosol generating material 3 is 1500 to 4000 grams. Preferably positioned within the mouthpiece 2'''', the burst strength when the aerosol supply system is used for less than 30 seconds to generate the aerosol is 1000 to 4000 grams. Even when exposed to temperatures above 58°C, for example 58°C to 70°C, the capsule 15 can maintain a burst strength within a range in which the consumer is known to be able to easily crush the capsule 15, and further provides the consumer with sufficient tactile feedback that the capsule 15 has broken. Maintaining such burst strength is achieved by selecting a suitable gelling agent for capsules, such as polysaccharides alone or in combination with gelatin, including, for example, gum arabic, gellan gum, acacia gum, xanthan gum, or carrageenan, as described herein. Furthermore, the capsule wall must be of a suitable thickness.

[0187] Preferably, when placed in a mouthpiece, the burst strength of the capsule before heating the aerosol-forming material is 2000-3500 grams or 2500-3500 grams. Preferably, when placed in a mouthpiece, the burst strength when the aerosol supply system is used for 30 seconds or less to generate the aerosol is 1500-4000 grams or 1750-3000 grams. In one example, when placed in a mouthpiece, the average burst strength of the capsule before heating the aerosol-forming material is approximately 3175 grams, and when placed in a mouthpiece, the average burst strength when the aerosol supply system is used for 30 seconds or less to generate the aerosol is approximately 2345 grams.

[0188] The burst strength of the capsule can be tested using load measuring instruments such as a Texture Analyser.

Suitable gels include agar, agarose, carrageenan, fruidan, and furcellan. Suitable waxes include carnauba wax. In some cases, the gelling agent may include carrageenan and / or gellan gum, and these gelling agents are particularly suitable for inclusion as gelling agents when the pressure required to break the resulting capsules is particularly appropriate.

[0191] The barrier material may contain one or more fillers such as starch, modified starch (such as oxidized starch), and sugar alcohols such as maltitol.

[0192] The barrier material may contain a coloring agent to facilitate the placement of capsules within the aerosol generating device during the manufacturing process of the aerosol generating device. The coloring agent is preferably selected from colorants and pigments.

[0193] The barrier material may further contain at least one buffer, such as a citrate compound or a phosphate compound.

[0194] The barrier material may further contain at least one plasticizer, which is glycerol, sorbitol, maltitol, triacetin, polyethylene glycol, propylene glycol, or another polyhydric alcohol having plasticity, and in particular one of any monoacid, diacid, or triacid forms such as citric acid, fumaric acid, or malic acid. The amount of plasticizer is in the range of 1 to 30% by weight, preferably 2 to 15% by weight, and more preferably 3 to 10% by weight, of the total dry weight of the shell.

[0195] The barrier material also contains one or more filler materials. Suitable filler materials include starch derivatives such as dextrin, maltodextrin, and cyclodextrin (alpha, beta, or gamma), or cellulose derivatives such as hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), methylcellulose (MC), and carboxymethylcellulose (CMC), polyvinyl alcohol, polyols, or mixtures thereof. Dextrin is a preferred filler material. The amount of filler in the shell is a maximum of 98.5% by weight, preferably 25-95% by weight, more preferably 40-80% by weight, and even more preferably 50-60% by weight, based on the total dry weight of the shell.

[0196] The capsule shell may include an additional hydrophobic outer layer to prevent the capsule from disintegrating due to moisture. The hydrophobic outer layer is preferably selected from the group including waxes, particularly carnauba wax, candelilla wax or beeswax, carbowax, shellac (in an alcoholic or aqueous solution), ethylcellulose, hydroxypropyl methylcellulose, hydroxypropylcellulose, latex compositions, polyvinyl alcohol, or combinations thereof. More preferably, at least one of the moisture barrier agents is ethylcellulose or a mixture of ethylcellulose and shellac.

[0197] The capsule core contains an aerosol modifier. This aerosol modifier may be any volatile substance that alters at least one property of the aerosol. For example, the aerosol substance may alter pH, sensory properties, moisture content, supply properties, or flavor. In some cases, the aerosol modifier may be selected from acids, bases, water, or flavoring agents. In some embodiments, the aerosol modifier includes one or more flavoring agents.

[0198] The flavorings may preferably include licorice, rose oil, vanilla, lemon oil, orange oil, mint flavoring, menthol and / or peppermint oil and / or spearmint oil, or peppermint oil from any species of the Mentha genus, or lavender, fennel, or anise.

[0199] In some cases, the flavoring agent may include menthol.

[0200] In some cases, the capsule may contain at least about 25% w / w of flavoring agent (based on the total weight of the capsule), preferably at least about 30% w / w of flavoring agent, 35% w / w of flavoring agent, 40% w / w of flavoring agent, 45% w / w of flavoring agent, or 50% w / w of flavoring agent.

Specifically, the capsule may contain flavoring in amounts ranging from 25 to 75% w / w (based on the total weight of the core), about 35 to 60% w / w, or about 40 to 55% w / w.

[0202] The capsule may contain at least about 2 mg, 3 mg, or 4 mg of an aerosol denaturant, preferably at least about 4.5 mg of an aerosol denaturant, 5 mg of an aerosol denaturant, 5.5 mg of an aerosol denaturant, or 6 mg of an aerosol denaturant.

[0204] Any suitable solvent may be used.

[0205] If the aerosol modifier contains a flavoring agent, the solvent may preferably contain short-chain or medium-chain oils. For example, the solvent may be C2-C 12 Triesters of glycerol such as triglycerides, preferably C6-C 10 Triglycerides or Cs-C 12 It may contain triglycerides. For example, the solvent may be a medium-chain triglyceride (MCT-C8-C8). 12 ) may also contain, which may be derived from palm oil and / or coconut oil.

[0206] The esters may be formed with caprylic acid and / or capric acid. For example, the solvent may contain a medium-chain triglyceride, which is caprylic acid triglyceride and / or capric acid triglyceride. For example, the solvent may contain compounds specified in the CAS registry by Nos. 73398-61-5, 65381-09-1, and 85409-09-2. Such medium-chain triglycerides are tasteless and odorless.

[0207] The hydrophilic-lipophilic balance (HLB) of the solvent may be in the range of 9 to 13, preferably 10 to 12. The capsule manufacturing method is extrusion, and selective centrifugation and curing and / or drying may be performed thereafter. This is incorporated by referring in whole to the contents of International Patent Publication 2007 / 010407A2.

[0208] Mouthpieces 2, 2', 2'', 2'''' and 2'''' can each be formed from any combination of the mouthpiece components described herein in other embodiments.

[0209] A non-combustible aerosol supply device is used to heat the aerosol generating material 3 of articles 1, 1', 1'', 1'''', 1'''' described herein. The non-combustible aerosol supply device preferably includes a coil, which has been shown to improve heat transfer to articles 1, 1', 1'', 1'''', 1'''' compared to other configurations.

[0210] In some cases, the coil is configured to heat at least one conductive heating element when in use, thereby allowing thermal energy to be conducted from that at least one conductive heating element to the aerosol generating material, which in turn causes the aerosol generating material to heat up.

[0211] In some examples, a coil is configured to generate a fluctuating magnetic field that passes through at least one heating element when in use, thereby causing inductive heating and / or magnetic hysteresis heating of at least one heating element. In such configurations, the heating element or each heating element may be referred to as a “susceptor” as defined herein. A coil configured to generate a fluctuating magnetic field that passes through one conductive heating element when in use, thereby causing inductive heating of at least one conductive heating element, may be referred to as an “induction coil” or “inductor coil.”

[0212] The device includes one or more heating elements, such as one or more conductive heating elements, which may be preferably positioned or configurable relative to a coil so as to be able to heat the one or more heating elements. The one or more heating elements may be fixed to the coil. Separately, at least one heating element, such as at least one conductive heating element, may be included in articles 1, 1' for insertion into the heating region of the device, and articles 1, 1' include an aerosol generating material 3 and are removed from the heating region after use. Separately, the device and such articles 1, 1' may each include at least one heating element, such as at least one conductive heating element, and the coil causes heating of the one or more heating elements of the device and each of the articles when the articles are in the heating region.

[0213] In some cases, the coil is helical. In some cases, the coil surrounds at least a portion of the heating area of ​​a device configured to contain an aerosol generating material. In some cases, the coil is a helical coil surrounding at least a portion of the heating area.

[0214] In some examples, the device includes a conductive heating element that at least partially encloses the heating area, and a coil that encloses at least a portion of the conductive heating element. In some examples, the conductive heating element is tubular. In some examples, the coil is an inductor coil. In some cases, the use of a coil allows a non-combustible aerosol supply device to reach its operating temperature faster than a non-coiled aerosol supply device. For example, a non-combustible aerosol supply device including a coil, as described above, can reach its operating temperature so that puffs are first supplied in less than 30 seconds, preferably less than 25 seconds, from the start of the device heating program. In some cases, the device can reach its operating temperature in about 20 seconds from the start of the device heating program.

[0215] It has been shown that using a coil, such as the one described herein, in a device to cause heating of the aerosol generating material improves the aerosol produced. For example, consumers have reported that aerosols emitted by devices containing coils such as those described herein are subjectively closer to those of factory-made cigarettes (FMCs) than aerosols produced by other non-combustion aerosol supply systems. While we do not wish to be bound by any theory, it is presumed that this is due to the reduced time required to reach the heating temperature when using a coil, the higher heating temperature achieved when using a coil, and / or the fact that the coil allows such a system to heat a relatively large amount of aerosol generating material simultaneously, resulting in an aerosol with a temperature similar to that of FMCs. In FMC products, the burning embers generate a hot aerosol that heats the tobacco in the tobacco rod after the embers as the aerosol is drawn through the rod. This hot aerosol is understood to release flavor compounds from the tobacco in the rod after the burning embers. A device including a coil as described herein can also heat an aerosol generating material such as tobacco material as described herein to release flavor compounds, and as a result, it is believed that an aerosol reported to be more similar to FMC aerosol can be obtained.

[0216] By using an aerosol supply system that includes a coil as described herein, for example, an induction coil that heats at least a portion of the aerosol generating material to at least 200°C, more preferably at least 220°C, it is possible to generate aerosols from the aerosol generating material that have specific properties considered to be more similar to aerosols of FMC products. For example, when an aerosol generating material containing nicotine is heated to at least 250°C for 2 seconds using an induction heater, one or more of the following characteristics were observed: At least 10 μg of nicotine is aerosolized from the aerosol generating material. The weight ratio of the aerosol-forming material to the nicotine in the generated aerosol is at least about 2.5:1, preferably at least 8.5:1. At least 100 μg of aerosol-forming material is aerosolized from the aerosol-generating material. The average particle size or droplet diameter in the generated aerosol is less than approximately 1000 nm. The aerosol density is at least 0.1 μg / cc.

[0217] In some cases, at least 10 μg of nicotine, preferably at least 30 μg or 40 μg of nicotine, is aerosolized from the aerosol generating material under an airflow of at least 1.50 L / m for two seconds. In some cases, less than about 200 μg, preferably less than about 150 μg or less than 125 μg of nicotine, is aerosolized from the aerosol generating material under an airflow of at least 1.50 L / m for two seconds.

[0218] In some cases, at least 100 μg, preferably at least 200 μg, 500 μg, or 1 mg of aerosol-forming material is aerosolized from the aerosol-generating material under an airflow of at least 1.50 L / m for a period of 2 seconds. Preferably, the aerosol-forming material may contain or consist of glycerol.

[0219] As defined herein, the term “average particle size or droplet diameter” means the average size of the solid or liquid components of an aerosol (i.e., components suspended in a gas). If the aerosol includes suspended liquid droplets and suspended solid particles, the term means the average size of all components combined.

[0220] In some cases, the average particle size or droplet diameter of the generated aerosol may be less than 900 nm, 800 nm, 700 nm, 600 nm, 500 nm, 450 nm, or 400 nm. In some cases, the average particle size or droplet diameter may be greater than approximately 25 nm, 50 nm, or 100 nm.

[0221] In some cases, the aerosol density generated during the above period may be at least 0.1 μg / cc. In some cases, the aerosol density is at least 0.2 μg / cc, 0.3 μg / cc, or 0.4 μg / cc. In some cases, the aerosol density is approximately 2.5 μg / cc, 2.0 μg / cc, 1.5 μg / cc, or less than 1.0 μg / cc.

[0222] The non-combustible aerosol supply device is configured to heat the aerosol generating material 3 of articles 1, 1', 1'', 1'''', 1'''' to a maximum temperature of preferably at least 160°C. Preferably, the non-combustible aerosol supply device is configured to heat the aerosol forming material 3 of articles 1, 1', 1'', 1'''', 1'''' to a maximum temperature of at least about 200°C, or at least about 220°C or at least about 240°C, more preferably at least about 270°C, at least once during the heating step by the non-combustible aerosol supply device. It has been done.

[0223] By using an aerosol supply system that includes a coil as described herein, for example, an induction coil that heats at least a portion of the aerosol generating material to at least 200°C, more preferably at least 220°C, it is possible to generate aerosols at a higher temperature from the aerosol generating material of articles 1, 1', 1'', 1''', 1'''' described herein than previous devices that contribute to the generation of aerosols that are considered to be closer to the FMC product when the aerosol exits the mouthpiece end of articles 2, 2', 2'', 2''''. For example, the maximum aerosol temperature measured at the mouthpiece end of articles 1, 1', 1'', 1''', 1'''' is preferably above 50°C, more preferably above 55°C, and even more preferably above 56°C or 57°C. Furthermore or separately, the maximum aerosol temperature measured at the mouthpiece end of articles 1, 1', 1'', 1''', 1'''' is less than 62°C, more preferably less than 60°C, and even more preferably less than 59°C. In some embodiments, the maximum aerosol temperature measured at the mouthpiece end of articles 1, 1', 1'', 1'''' is preferably 50°C to 62°C, more preferably 56°C to 60°C.

[0224] Figure 6 shows an example of a non-combustible aerosol supply device 100 for generating aerosols from aerosol generating media / materials such as the aerosol generating material 3 of articles 1, 1', 1'', 1'''', and 1'''' described herein. In general, device 100 may be used to heat a replaceable article 110 containing an aerosol generating medium, such as articles 1, 1', 1'', 1'''', and 1'''' described herein, in order to generate aerosols or other inhalable media that are inhaled by the user of device 100. Device 100 and the replaceable article 110 together form a system.

[0225] Device 100 includes a housing 102 (in the form of an outer cover) that encloses and accommodates various components of device 100. Device 100 has an opening 104 at one end through which an article 110 is inserted for heating by a heating assembly. When in use, the article 110 is fully or partially inserted into the heating assembly and heated thereby by one or more components of the heating assembly.

[0226] The device 100 in this example includes a first end member 106, which includes a lid 108, which is movable relative to the first end member 106 to close the opening 104 when the article 110 is not in place. In Figure 6, the lid 108 is shown in an open configuration, but the lid 108 may be moved into a closed configuration. For example, the user slides the lid 108 in the direction of arrow "B".

[0227] Device 100 may include a user-operable adjustment member 112, such as a button or switch, which activates device 100 when pressed. For example, the user may operate the switch 112 to power on device 100.

[0228] Device 100 also includes electrical components such as sockets / ports 114, which may house cables for charging the device 100's battery. Socket 114 may be a charging port, such as a USB charging port.

[0229] Figure 7 shows the device 100 from Figure 6 with the outer cover 102 removed and the article 110 absent. The device 100 defines a longitudinal axis 134.

[0230] As shown in Figure 7, the first end member 106 is positioned at one end of the device, and the second end member 116 is positioned at the opposite end of the device 100. The first and second end members 106 and 116 both define at least partially the end faces of the device 100. For example, the bottom surface of the second end member 116 defines at least partially the bottom surface of the device 100. The edge of the outer cover 102 also defines part of the end face. In this example, the lid 108 also defines part of the top surface of the device 100.

[0231] The end of the device closest to the opening 104 is also known as the proximal end (or mouthpiece end) of the device 100, as it is closer to the user's mouth during use. During use, the user inserts an item 110 into the opening 104, operates the user control unit to start heating the aerosol generating material, and inhales the aerosol generated in the device. This causes the aerosol to flow into the device 100 along the flow path toward the proximal end of the device 100.

[0232] The other end of the device, away from the opening 104, is the end that moves away from the user's mouth during use and is therefore also known as the distal end of device 100. When a user inhales the aerosol generated in the device, the aerosol flows away from the distal end of device 100.

[0233] Device 100 further includes a power source 118. The power source 118 may be a battery, such as a rechargeable or non-rechargeable battery. Suitable battery examples include lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically connected to the heating assembly and supplies power as needed and under the control of a controller (not shown) to heat the aerosol generating material. In this example, the battery is connected to a central support 120 that holds the battery 118 in place.

[0234] The device further includes at least one electronic module 122. The electronic module 122 may include, for example, a printed circuit board (PCB). The PCB 122 may support at least one processor and a controller such as memory. The PCB 122 may also include one or more electrical tracks that electrically connect various electronic components of the device 100 together. For example, battery terminals are electrically connected to the PCB 122 so that power can be distributed throughout the device 100. The socket 114 may also be electrically coupled to the battery via the electrical tracks.

[0235] In the example of device 100, the heating assembly is an induction heating assembly and includes various components for heating the aerosol generating material of article 110 via an induction heating process. Induction heating is the process of heating a conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may include induction members, for example, one or more inductor coils, and a device for passing a fluctuating current, such as an alternating current, through the induction members. The fluctuating current in the induction members generates a fluctuating magnetic field. The fluctuating magnetic field preferably penetrates a susceptor positioned relative to the induction members, generating eddy currents inside the susceptor. The susceptor has electrical resistance to eddy currents, and therefore the flow of eddy currents against this resistance causes the susceptor to be heated by Joule heating. If the susceptor contains a ferromagnetic material such as iron, nickel, or cobalt, heat may also be generated by magnetic hysteresis losses within the susceptor, i.e., by a change in the orientation of the magnetic dipoles of the magnetic material as a result of matching the fluctuating magnetic field. In induction heating, for example, heat is released into the susceptor compared to conduction heating, enabling rapid heating. Furthermore, there is no need for any physical contact between the dielectric heater and the susceptor, which increases the flexibility of the structure and application.

[0236] The induction heating assembly in example device 100 includes a susceptor structure 132 (hereinafter referred to as "susceptor"), a first inductor coil 124, and a second inductor coil 126. The first and second inductor coils 124 and 126 are made from a conductive material. In this example, the first and second inductor coils 124 and 126 are made from Litz wire / cable, which is wound spirally to provide helical inductor coils 124 and 126. Litz wire consists of multiple individual wires, which are individually insulated and twisted together to form a single wire. Litz wire is designed to reduce skin effect losses in the conductor. In example device 100, the first and second inductor coils 124 and 126 are made from copper Litz wire with a rectangular cross-section. In other examples, the Litz wire may have a cross-section of other shapes, such as circular.

[0237] The first inductor coil 124 is configured to generate a first fluctuating magnetic field for heating a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second fluctuating magnetic field for heating a second section of the susceptor 132. In this example, the first inductor coil 124 is adjacent to the second inductor coil 126 in the direction along the longitudinal axis 134 of the device 100 (i.e., the first and second inductor coils 124 and 126 do not overlap). The susceptor structure 132 may consist of a single susceptor or two or more susceptors. The ends 130 of the first and second inductor coils 124 and 126 are connected to the PCB 122.

[0238] Naturally, in some examples, the first and second inductor coils 124 and 126 may have at least one different characteristic from each other. For example, the first inductor coil 124 may have at least one different characteristic from the second inductor coil 126. For example, in one example, the first inductor coil 124 may have a different inductance value from the second inductor coil 126. In Figure 7, the first and second inductor coils 124 and 126 differ in length such that the first inductor coil 124 is wound on a smaller section of the susceptor 132 than the second inductor coil 126. Thus, the first inductor coil 124 may have a different number of turns from the second inductor coil 126 (assuming the spacing between individual turns is substantially the same). In yet another example, the first inductor coil 124 may be made from a different material than the second inductor coil 126. In some examples, the first and second inductor coils 124 and 126 may be substantially the same.

[0239] In this example, the first and second inductor coils 124 and 126 are shown wound in opposite directions. This is useful when the inductor coils are active at different times. For example, the first inductor coil 124 may be actuated first to heat a first section / part of article 110, and then the second inductor coil 126 may be actuated to heat a second section / part of article 110. Winding the coils in different directions helps reduce the current induced in the inductor coils when used with certain types of control circuits. In Figure 7, the first inductor coil 124 is a right-handed helix and the second inductor coil 126 is a left-handed helix. However, in another embodiment, the inductor coils 124 and 126 may be wound in the same direction, or the first inductor coil 124 may be a left-handed helix and the second inductor coil 126 may be a right-handed helix.

[0240] In this example, the susceptor 132 is hollow and thus defines a receiving portion within which an aerosol generating material is contained. For example, article 110 is inserted into the susceptor 132. In this example, the susceptor 132 is tubular and has a circular cross-section.

[0241] The susceptor 132 may be made from one or more materials. Preferably, the susceptor 132 includes carbon steel having a nickel or cobalt coating.

[0242] In some examples, the susceptor 132 may contain at least two materials, which can be heated at two different frequencies for the selective aerosolization of the at least two materials. For example, a first section of the susceptor 132 (heated by a first inductor coil 124) may contain a first material, and a second section of the susceptor 132 (heated by a second inductor coil 126) may contain a different second material. In another example, the first section may contain first and second materials, which may be heated separately based on the operation of the first inductor coil 124. The first and second materials may be adjacent along an axis defined by the susceptor 132, or they may form different layers within the susceptor 132. Similarly, the second section may contain third and fourth materials, which may be heated separately based on the operation of the second inductor coil 126. The third and fourth materials may be adjacent to each other along the axis defined by the susceptor 132, or they may form different layers within the susceptor 132. For example, the third material may be the same as the first material, and the fourth material may be the same as the second material. Separately, each of these materials may be different. The susceptor may include, for example, carbon steel or aluminum.

[0243] The device 100 in Figure 7 is generally tubular and further includes an insulating member 128 that at least partially surrounds the susceptor 132. The insulating member 128 may be made of any insulating material, such as plastic. In this particular example, the insulating member is made of polyetheretherketone (PEEK). The insulating member 128 helps to insulate the various components of the device 100 from the heat generated inside the susceptor 132.

[0244] The insulating member 128 may also fully or partially support the first and second inductor coils 124 and 126. For example, as shown in Figure 7, the first and second inductor coils 124 and 126 are positioned around the insulating member 128 and in contact with the radially outward surface of the insulating member 128. In some examples, the insulating member 128 does not contact the first and second inductor coils 124 and 126. For example, a small gap may exist between the outer surface of the insulating member 128 and the inner surfaces of the first and second inductor coils 124 and 126.

[0245] In a specific example, the susceptor 132, the insulating member 128, and the first and second inductor coils 124 and 126 are coaxial with respect to the central longitudinal axis of the susceptor 132.

[0246] Figure 8 is a side view showing a partial cross-section of device 100. The outer cover 102 is shown in this example. The rectangular cross-sectional shapes of the first and second inductor coils 124 and 126 are more clearly visible.

[0247] The device 100 further includes a support 136 that engages with one end of the susceptor 132 to hold the susceptor 132 in place. The support 136 is connected to the second end member 116.

[0248] The device also includes a second printed circuit board 138 associated with the adjustment member 112.

[0249] Device 100 further includes a second lid / cap 140 and a spring 142 located toward the distal end of device 100. The spring 142 opens the second lid 140, allowing access to the susceptor 132. The user may open the second lid 140 to clean the susceptor 132 and / or support 136.

[0250] The device 100 further includes an expansion chamber 144 extending away from the proximal end of the susceptor 132 toward the opening 104 of the device. At least partially located within the expansion chamber 144 is a retaining clip 146 that contacts and holds the article 110 when housed within the device 100. The expansion chamber 144 is connected to an end member 106.

[0251] Figure 9 is an exploded view of the device 100 from Figure 8, with the outer cover 102 omitted.

[0252] Figure 10A is a cross-sectional view of a portion of the device 100 in Figure 8. Figure 10B is an enlarged view of a region in Figure 10A. Figures 8A and 8B show an article 110 housed within a susceptor 132, with dimensions such that its outer surface contacts the inner surface of the susceptor 132. This ensures the most efficient heating. In this example, the article 110 includes an aerosol generating material 110a, which is positioned within the susceptor 132. The article 110 may also include other components such as a filter packaging material and / or a cooling structure.

[0253] Figure 10B shows that the outer surface of the susceptor 132 is separated from the inner surfaces of the inductor coils 124 and 126 by a distance of 150, measured perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 150 is approximately 3mm to 4mm, and approximately 3 to 3.5mm. , or approximately 3.25 mm.

[0254] Figure 10B further shows that the outer surface of the insulating member 128 is separated from the inner surface of the inductor coils 124 and 126 by a distance 152 measured perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 152 is approximately 0.05 mm. In another example, the distance 152 is substantially 0 mm, so that the inductor coils 124 and 126 are in contact with and touching the insulating member 128.

[0255] In one example, the wall thickness of susceptor 132 is approximately 0.025 mm to 1 mm, or approximately 0.05 mm.

[0256] In one example, the length of susceptor 132 is approximately 40mm to 60mm, approximately 40mm to 45mm, or approximately 44.5mm.

[0257] In one example, the wall thickness 156 of the insulating member 128 is approximately 0.25 mm to 2 mm, 0.25 mm to 1 mm, or approximately 0.5 mm.

[0258] During use, articles 1, 1', 1'', 1'''', 1'''' described herein are inserted into a non-combustible aerosol supply device, such as device 100, as described with reference to Figures 6-10. At least portions of the mouthpieces 2, 2', 2'', 2'''', 2'''' of articles 1, 1', 1'', 1'''', 1'''' protrude from the non-combustible aerosol supply device 100 and are placed in the user's mouth. Aerosol is generated by heating the aerosol generating material 3 using device 100. The aerosol generated by the aerosol generating material 3 travels through the mouthpieces 2, 2', 2'', 2'''', 2'''' to the user's mouth.

[0259] Articles 1, 1', 1'', 1''', and 1'''' described herein are particularly advantageous when used in non-combustible aerosol supply devices, such as device 100, as described with reference to Figures 6-10. Surprisingly, amorphous solid material 6 has been found to have a particularly significant effect on the temperature of the aerosol delivered to the suction end of articles 1, 1', 1'', 1''', and 1''''.

[0260] The tests were conducted on two comparative smoking articles and an exemplary embodiment of the present invention. Comparative Examples A and B are the same as Article 1'' except that Comparative Examples A and B contain a fibrous material 4 instead of an amorphous solid material 6. Comparative Example A has a ventilation level of 60%, and Comparative Example B has a ventilation level of 75%. The exemplary article is the same as Article 1'' and is provided with 60% ventilation.

[0261] The test was performed on the first 2 puffs of the article. Each sample was tested 9 times, and the obtained temperature is the average of these 9 tests. The known Health Canada Intense puffing regime (55 ml puff volume applied for 2 seconds every 30 seconds) was applied using standard test equipment . The test results are shown in Table 1, where the puff temperature indicates the difference between room temperature and the aerosol temperature.

[0262] As shown in Table 1, the aerosol temperature over the first and second puffs from an exemplary article comprising an amorphous solid material body is lower than the aerosol temperature over those puffs of either Comparative Example A or B. The aerosol temperature over puff 1 and puff 2 of the exemplary article with 60% ventilation corresponds to the aerosol temperature over puff 1 and puff 2 of Comparative Example B with 75% ventilation. A higher ventilation level has the effect of cooling the aerosol temperature, and therefore it is significant to achieve an equivalent aerosol temperature in an article with a ventilation level of 15% or less.

Table 1

[0264] Figure 11 illustrates a method of manufacturing an article for use in a non-combustion aerosol supply system. In step S101, a sheet-shaped amorphous solid material source is passed through an apparatus to form a rod of gathered amorphous solid material from the sheet material.

[0265] In step S102, the gathered rod of amorphous solid material is cut to a length for forming an amorphous solid material body as defined herein.

[0266] Figure 12 is a side view of an apparatus for manufacturing a material body rod according to the present specification.

[0267] Figure 12 shows an apparatus 200 for manufacturing a material body according to the present invention, comprising a tongue portion 211 and a guide nozzle 212 including a funnel portion. The tongue portion 211 is a tapered duct having a wide inlet opening 211b and a narrow outlet opening 211a. The tongue portion 211 is substantially circular in cross-section, and may be open on its lower side in the form of an elongated slot (not shown) extending along the length of the tongue portion in the axial direction such that the tongue portion does not form a complete circle in cross-section. The tongue portion 211 may be positioned on a guide (not shown) including a forming track, along which a continuous belt or "garniture" 215 extends. The garniture 215 extends over a plurality of guide rollers 216 and is driven to be conveyed around the rollers 216 in the direction indicated by arrow "A". Wrapper paper "P" is fed from a spool 217 onto the upper surface of the garniture 215, and is conveyed through the tongue portion 211 by the moving garniture 215. When the wrapper paper P travels within the tongue portion 211, the forming track deforms the garniture and the wrapper paper thereon such that, in cross-section, the wrapper paper P changes from a flat state when it enters the wide inlet opening 211b of the tongue portion 211 (as it is when in the spool) to a closed circle when it exits the narrow outlet opening 211a of the tongue portion 211, so as to completely surround the formed rod.

[0268] In use, a bobbin of amorphous solid material (not shown) is fed into the funnel of the guide nozzle 212 and guided into the tongue portion 211, and the amorphous solid material is fed into the continuously tapered tongue portion 211 to form a sheet of amorphous solid material into a rod by gathering the material as it exits the narrow distal end 211a.

[0269] When amorphous solid material is supplied into the tongue portion 211, it is gathered onto the wrapper paper P being transported on the garnish 215 and transported together within the tongue portion 211. As the amorphous solid material moves within the tongue portion 211, the material is compressed because the tongue portion 211 tapers inward, and the wrapper paper P is folded around the outside of the compressed cylinder made of the gathered amorphous solid material so that the amorphous solid material exits through the narrow exit opening 211a of the tongue portion 211, forming a compressed cylindrical rod surrounded by the outer wrapper paper P.

[0270] The rod formed by the method described herein is cut to a length necessary for forming multiple material bodies according to the present invention.
