Suitable heat effect agents may be, but are not limited to, vanillyl ethyl ether, and suitable cooling agents may be, but are not limited to, eucalyptol, WS-3.

[0034] An aerosol-generating material is a material that can generate an aerosol when, for example, heated, irradiated, or energized by any other method. The aerosol-generating material may be in the form of, for example, a solid, liquid, or gel, and it may or may not contain an active substance and / or a flavorant. In some embodiments, the aerosol-generating material may include an "amorphous solid" (which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous)). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, within it. In some embodiments, the aerosol-generating material may include, for example, about 50 wt%, 60 wt%, or 70 wt% to about 90 wt%, 95 wt%, or 100 wt% of an amorphous solid.

[0035] The aerosol-generating material may include one or more active substances and / or fragrances, one or more aerosol-forming materials, and optionally, one or more other functional materials.

[0036] The aerosol-forming material may include one or more components that can form an aerosol. In some embodiments, the aerosol-forming material may include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0037] The one or more other functional materials may include one or more of a pH adjuster, a colorant, a preservative, a binder, a filler, a stabilizer, and / or an antioxidant.

[0038] The material may be present on or in a support to form a substrate. The support may be, for example, paper, card, cardboard, thick paper, recycled material, plastic material, ceramic material, composite material, glass, metal, or alloy, or may include them. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

[0039] A consumable is an article that contains or consists of an aerosol-forming material, and part or all of which is intended to be consumed by a user during use. The consumable may comprise one or more other components such as an aerosol-forming material storage region, an aerosol-forming material transfer component, an aerosol-forming region, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. The consumable may also comprise an aerosol generator such as a heater that releases heat to generate an aerosol from the aerosol-forming material during use. The heater may comprise, for example, a combustible material, a material heatable by electrical conduction, or a susceptor.

[0040] A susceptor is a material heatable by the penetration of a varying magnetic field such as an alternating magnetic field. The susceptor may be a conductive material, such that the varying magnetic field penetrates it, causing the heating material to be inductively heated. The heating material may be a magnetic material, such that the varying magnetic field penetrates it, causing the heating material to be heated by magnetic hysteresis. The susceptor may have both conductivity and magnetism, such that the susceptor is heatable by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

[0041] An aerosol modifier is a substance configured to modify the generated aerosol, for example, by changing the taste, flavor, acidity, or another characteristic of the aerosol. The aerosol modifier may be provided in an aerosol modifier release component operable to selectively release the aerosol modifier.

[0042] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may include, for example, one or more of 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 in the form of a powder, a thread, or granules. The aerosol modifier may not have a filter medium.

[0043] 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 subject the aerosol generating material to thermal energy, and as a result, release one or more volatile components from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from the aerosol generating material without heating. For example, the aerosol generator may be configured to subject the aerosol generating material to one or more of vibration, a pressure increase, or electrostatic energy.

[0044] Articles, such as rod-shaped articles, are often named "Regular" (typically in the range of 68 - 75 mm, for example, about 68 mm to about 72 mm), "Short" or "Mini" (less than 68 mm), "King Size" (typically in the range of 75 - 91 mm, for example, about 79 mm to about 88 mm), "Long" or "Super King" (typically in the range of 91 - 105 mm, for example, about 94 mm to about 101 mm), and "Ultra Long" (typically in the range of about 110 mm to about 121 mm) according to the length of the product.

[0045] Articles are also named "Regular" (about 23 - 25 mm), "Wide" (more than 25 mm), "Slim" (about 22 - 23 mm), "Slim Slim" (about 19 - 22 mm), "Super Slim" (about 16 - 19 mm), and "Micro Slim" (less than about 16 mm) according to the outer circumference of the product.

[0046] Therefore, for example, the length of an article in king size and super-slim format is about 83 mm and the outer circumference is about 17 mm.

[0047] Each format may be made with mouthpieces of different lengths. The length of the mouthpiece is about 30 mm to 50 mm. The chip paper connects the mouthpiece to the aerosol-generating material and is usually longer than the mouthpiece, for example 3 to 10 mm longer, such that the chip paper covers the mouthpiece and overlaps the aerosol-generating material in the form of a rod of base material, connecting the mouthpiece to the rod.

[0048] The articles described herein, as well as their aerosol-generating materials and mouthpieces, can be made in any of the above formats, although not limited thereto.

[0049] As used herein, the terms "upstream" and "downstream" are relative terms defined in relation to the direction of the main stream aerosol drawn through the article or device during use.

[0050] The filament tow material described in this specification can include cellulose acetate fiber tows. The filament tow can also 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, cotton, aliphatic polyester materials, and polysaccharide polymers, or combinations thereof. The filament tow may be plasticized with a plasticizer suitable for the tow, such as triacetin if the material is cellulose acetate tow, or the tow may be unplasticized. The tow can have any suitable specifications, such as other cross-sections like "Y" shape or "X" shape, a denier value per filament of 2.5 to 15 denier, for example, 8.0 to 11.0 denier per filament, and a total denier value of 5,000 to 50,000 denier, for example, 10,000 to 40,000 denier.

[0051] As used herein, the term "tobacco material" refers to any material that includes tobacco or its derivatives or substitutes. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The tobacco material may include one or more of ground tobacco, tobacco fiber, shredded tobacco, extruded tobacco, tobacco stems, tobacco leaf stalks, reconstituted tobacco, and / or tobacco extracts.

[0052] In the figures described in this specification, like reference numerals are used to indicate like features, articles, or components.

[0053] FIG. 1 is a side cross-sectional view of article 1 for use as part of a non-combustible aerosol supply system.

[0054] Article 1 includes an aerosol-generating material 3, in this example a cylindrical rod of tobacco material, and a downstream portion connected to the aerosol-generating material 3 so as to be downstream of the aerosol-generating material 3, in this example called a mouthpiece 2. The aerosol-generating material 3 supplies an aerosol when heated within a non-combustible aerosol supply device (for example, a non-combustible aerosol supply device provided with a coil) that forms a system, as described herein. In other embodiments, Article 1 can include its own heat source and forms an aerosol supply system without the need for a separate aerosol supply device.

[0055] The aerosol-generating material 3, also referred to herein as the aerosol-generating substrate 3, includes at least one aerosol-forming material. In this example, the aerosol-forming material is glycerol. As an alternative, the aerosol-forming material can be another material or a combination thereof as described herein, for example propylene glycol.

[0056] In this example, the mouthpiece includes a tubular portion 4a formed by a hollow tube, also referred to herein as a cooling element in this example. The mouthpiece 2 includes, in this example, a component including a material body 6 downstream of the tubular portion 4a. In this example, the material body 6 is adjacent to and in contact with the tubular portion 4a. The material body 6 and the tubular portion 4a each define a substantially cylindrical overall outer shape and share a common longitudinal axis.

[0057] In this example, the material body 6 of the component is formed from a corrugated sheet material. In this example, the material body comprises a corrugated sheet material formed to have a corrugation pattern with a series of substantially parallel ridges and grooves, and the average distance between adjacent ridges is wider than about 0.3 mm. In addition, in this example, the amplitude of the corrugation is smaller than about 0.7 mm. In other examples, the sheet material can include either an average distance between adjacent ridges wider than about 0.3 mm or an amplitude of the corrugation smaller than about 0.7 mm. Alternatively, the amplitude of the corrugation can be from 0.7 mm to 1.2 mm. In any of these examples, the average density of the material body is from about 0.1 to about 0.25 mg / mm 3 can be set.

[0058] The amplitude of the corrugation (also known as the "crimp factor") refers to the depth of the groove formed by corrugating the sheet material that forms the body. That is, when the sheet material is corrugated, as shown in FIG. 2B, a plurality of peaks and valleys are formed in the sheet material when viewed from the first side of the sheet material. Here, the amplitude "A" of the corrugation is the depth of the valley measured from the peak. The corrugation may form a "zigzag" pattern or other shape. In some embodiments, the distance between adjacent grooves of the corrugated sheet material ranges from 0.3 to 2 mm, preferably from 0.4 to 1 mm, that is, the pitch [P] is within these ranges. In some embodiments, the distance between adjacent grooves of the corrugated sheet material is at least 0.4 mm, or at least 0.5, 0.6, 0.7, or 0.8 mm. In some embodiments, the distance between adjacent grooves of the corrugated sheet material 10 is at most 1.5 mm, preferably at most 1.4, 1.3, 1.2, 1.1, or 1.0 mm. For example, the sheet material can have a corrugation with an amplitude smaller than a distance of 500 μm and a distance between peaks (or valleys) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0059] In some embodiments, the sheet material 10 is heated when being corrugated. For example, the sheet material 10 may be passed between corrugating rollers, and one or both of the corrugating rollers are heated.

[0060] It is advantageous that it has been found that using a sheet material, such as paper, having the above-described corrugation pitch and / or amplitude for components of an aerosol supply system shows an improvement in performance. In particular, these relatively small levels of corrugation pitch and amplitude surprisingly result in a lower pressure drop of the material body compared to a body formed from a sheet material with a larger level of corrugation.

[0061] In this example, the density of the material body 6 is about 0.19 mg / mm 3 . In some embodiments, the density of the body 6 is at least 0.1 mg / mm 3 , 0.12 mg / mm 3 , or 0.15 mg / mm 3 . Alternatively or in addition, the density of the material body 6 can be less than about 0.3 mg / mm 3 , less than 0.25 mg / mm 3 , or less than 0.22 mg / mm 3 . It is advantageous that the density of the material body can be from about 0.15 mg / mm 3 to about 0.25 mg / mm 3 . These values include any additives contained within the material body 6. Before being corrugated to form the material body, the density of the sheet material can be from about 0.2 to 0.5 mg / mm 3 , for example, about 0.25, 0.30, or 0.35 mg / mm 3 .

[0062] In some embodiments, the sheet material comprises fibers having a length in the range of 2 mm to 6 mm. Such fibers have the advantage of being a material that is less likely to absorb and retain an aerosol-forming agent (e.g., glycerol as in this example) and / or an aerosol modifier (e.g., menthol). Thus, with a material body including such fibers, a larger amount of the aerosol-forming agent and / or aerosol modifier may be able to reach the user's mouth through the material body. In some embodiments, the material body comprises fibers having a length in the range of 2 mm to 5 mm, 2 mm to 4 mm, or 2 mm to 3 mm.

[0063] The material body can comprise fibers having a length of one or more of about 2 mm, about 2.5 mm, about 3 mm, about 3.5 mm, about 4 mm, about 4.5 mm, about 5 mm, about 5.5 mm, and about 6 mm.

[0064] The length of the fibers can be measured according to an appropriate standard, and the above-mentioned fiber length can be the length-weighted average value of the fiber lengths.

[0065] The material body 6 may be formed from a continuous web of the sheet material 6A. In this example, the sheet material 6A is pleated in a manner similar to a "crepe filter" to form the material body 6. The sheet material 6A can be manufactured using a CU-20 filter manufacturing machine manufactured by Decoufle (trademark). However, those skilled in the art will understand that other machines can be used to manufacture the material body 6.

[0066] In this example, the sheet material 6A contains cellulose. In this example, the sheet material 6A is paper.

[0067] In some embodiments, the width of the continuous web of the sheet material 6A is at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, or at least 120 mm.

[0068] In some embodiments, the width of the continuous web of sheet material 6A is at most 240 mm, at most 230 mm, at most 220 mm, at most 210 mm, at most 200 mm, or at most 190 mm.

[0069] In some embodiments, the width of the sheet material is in the range of 120 mm to 200 mm, in the range of 150 mm to 190 mm, in the range of 160 mm to 190 mm, or in the range of 160 mm to 180 mm.

[0070] The thickness of the sheet material can be from about 50 to about 100 μm, or from about 60 to about 90 μm. In one example, the sheet material is paper with a thickness of 60 - 70 μm and a basis weight of 30 - 40 g / m 2 2.

[0071] In addition to or instead of this, the sheet material 6A may include different materials. For example, in some embodiments, the sheet material 6A includes reconstituted tobacco formed on the sheet material 6A arranged to form the material body 6. The reconstituted tobacco includes cellulose. In another embodiment (not shown), the reconstituted tobacco is manufactured into a uniform plug of the material forming the body 6. The reconstituted tobacco may optionally be paper reconstituted tobacco.

[0072] In some embodiments, the sheet material 6A includes paper with a basis weight in the range of 15 gsm to 80 gsm, or in the range of 20 gsm to 50 gsm.

[0073] In some embodiments, the basis weight of the sheet material 6A is at least 15 gsm, at least 20 gsm, at least 25 gsm, or at least 30 gsm.

[0074] In some embodiments, the basis weight of the sheet material is 100 gsm or less, 90 gsm or less, 80 gsm or less, or 70 gsm or less. Preferably, the basis weight of the sheet material is 60 gsm or less, 50 gsm or less, or 40 gsm or less.

[0075] In some embodiments, the weighing of the sheet material is in the range of 20 gsm to 40 gsm, in the range of 24 gsm to 36 gsm, or in the range of 30 gsm to 40 gsm.

[0076] The material body 6 is wrapped by the first plug wrap 7. In this example, the tubular portion 4a and the material body 6 are combined using a second plug wrap 9 wound around the circumferences of both these sections. The chip paper 5 is wound to cover the entire length of the mouthpiece 2 and a part of the rod of the aerosol-generating material 3 and has an adhesive on its inner surface for connecting the mouthpiece 2 and the rod 3.

[0077] In this example, the tubular portion 4a is formed from multiple layers of paper, and these papers are wound parallel to each other and abut at the seams to form a hollow tube. In this example, the first and second paper layers are provided as a double tube, but in other examples, three, four, or five or more paper layers can be used to form a triple, quadruple, or quintuple or more tube. Other structures can be used, such as a layer of spirally wound paper, a cardboard tube, a tube formed using a papier-mâché type process, a molded or extruded plastic tube, etc.

[0078] In some embodiments, the wall thickness of the tubular portion is at least about 150 μm to a maximum of about 2 mm, 200 μm to 1.5 mm, or 250 μm to 1 mm. In this example, the wall thickness of the tubular portion is about 300 μm. The "wall thickness" of the tubular portion corresponds to the thickness of the wall in the radial direction of the tubular portion. This can be measured, for example, using calipers.

[0079] The ventilation level of article 1 is about 75% of the aerosol drawn through the article. In alternative embodiments, the ventilation level of the article can be 50% - 80%, for example 65% - 75%, of the aerosol drawn through the article. These levels of ventilation help to slow down the flow of the aerosol drawn through the mouthpiece 2, such that the temperature of the aerosol can be sufficiently lowered before the aerosol reaches the downstream end 2b of the mouthpiece 2. The ventilation is supplied directly into the mouthpiece 2 of the article 1. In this example, the ventilation is supplied into the tubular portion 4a, which has been found to be particularly beneficial in assisting the aerosol generation process. The ventilation is, in this case, supplied through first and second parallel rows of ventilation holes 12 formed as laser perforations, which are located at positions 13.925 mm and 14.625 mm respectively from the mouth-side end 2b downstream of the mouthpiece 2. These ventilation holes 12 pass through the chip paper 5, the second plug wrap 9, and the tubular portion 4a. In alternative embodiments, the ventilation can be supplied into the mouthpiece at other positions. For example, the ventilation may be supplied into the material body 6.

[0080] Alternatively, the ventilation can be supplied into the portion of the article where the tubular body 4a is disposed through a single row of ventilation holes, such as laser perforations. It has been found that this improves the formation of the aerosol. This is presumably due to the air flow through these ventilation holes being more uniform than through multiple rows of ventilation holes for a given ventilation level.

[0081] In some examples, the aerosol generating material 3 described herein is the first aerosol generating material, and the tubular portion 4a may include a second aerosol generating material. In one example, the wall 4b of the tubular portion 4a includes the second aerosol generating material. For example, the second aerosol generating material can be disposed on the inner surface of the wall 4b of the tubular portion 4a.

[0082] The second aerosol-generating material comprises at least one aerosol-forming material and also comprises at least one aerosol modifier or other sensory material. The aerosol-forming material and / or the aerosol modifier can be any of the aerosol-forming materials or aerosol modifiers as described herein or a combination thereof.

[0083] As used herein, when the aerosol generated from the aerosol-generating material 3, referred to as the first aerosol, is drawn through the tubular portion 4a of the mouthpiece, the heat from the first aerosol can aerosolize the aerosol-forming material of the second aerosol-generating material to form a second aerosol. The second aerosol can be a flavorant that can be any of the flavorants described herein and may include a flavorant that can supplement or complement the flavor of the first aerosol.

[0084] Attaching the second aerosol-generating material to the tubular body 4a can generate a second aerosol that enhances or supplements the flavor or appearance of the first aerosol.

[0085] In this example, the outer circumference of article 1 is approximately 21 mm (i.e., the article is in a demi-slim format). In some embodiments, article 1 has a rod of aerosol-forming material with an outer circumference longer than 19 mm. It has been found that this provides a sufficient outer circumference to produce an improved and sustained aerosol over a normal aerosol generation session preferred by consumers. When the article is heated, heat is transferred through the rod of aerosol-forming material 3, volatilizing the components of the rod, and it has been found that an outer circumference longer than 19 mm is particularly effective in producing such an aerosol. Since the article is heated to emit an aerosol, using an article with an outer circumference shorter than approximately 23 mm can improve the heating efficiency. To achieve an improvement in the aerosol by heating while maintaining a suitable product length, an outer circumference of the rod longer than 19 mm and shorter than 23 mm is preferred. In some examples, the outer circumference of the rod can be between 20 mm and 22 mm, which has been found to provide a good balance between providing effective aerosol delivery and enabling efficient heating.

[0086] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod of aerosol-forming material 3, and as a result, there is a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm.

[0087] In some examples, the tip paper 5 contains a citrate such as sodium citrate or potassium citrate. In such examples, the citrate content of the tip paper 5 may be 2 wt% or less, or 1 wt% or less. Reducing the citrate content of the tip paper 5 is thought to help reduce the carbonization phenomenon that may occur during use.

[0088] In this example, the chip paper 5 extends 5 mm to cover the rod of the aerosol-generating material 3. Instead, it can extend 3 mm to 10 mm, or 4 mm to 6 mm to cover the rod 3, so as to surely adhere between the suction port 2 and the rod 3. The weight of the chip paper 5 can be greater than the weight of the plug wrap used for the article 1. For example, it can be 40 gsm to 80 gsm, or 50 gsm to 70 gsm, and in this example, it can be 58 gsm. At these weights within these ranges, it has been found that the chip paper has sufficient flexibility to wrap around the article 1 while having an acceptable tensile strength and adhere to itself along the longitudinal lap seam of the paper. The outer circumference of the chip paper 5 becomes approximately 21 mm when wrapped around the suction port 2.

[0089] In some embodiments, the weight of the first plug wrap 7 is less than 50 gsm, for example, about 20 gsm to 40 gsm. However, it should be recognized that the weight of the first plug wrap 7 can be greater to increase the firmness of the suction port. For example, the weight of the first plug wrap 7 can be at least 50 gsm, at least 60 gsm, at least 70 gsm, at least 80 gsm, at least 90 gsm, or at least 100 gsm. In some embodiments, the weight of the first plug wrap 7 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.

[0090] In some embodiments, the weight of the first plug wrap 7 is at least 20 gsm, or at least 30 gsm. In some embodiments, the weight of the first plug wrap 7 is at most 120 gsm, 110 gsm, or 100 gsm. In some embodiments, the weight of the first plug wrap 7 is in the range of 20 gsm to 120 gsm, or in the range of 30 gsm to 100 gsm.

[0091] In some embodiments, the thickness of the first plug wrap 7 is 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be recognized that the thickness weight of the first plug wrap 7 may be thicker in order to increase the firmness of the suction port. In some embodiments, for example, the thickness of the first plug wrap 7 may be at least 40 microns, 50 microns, 60 microns, 70 microns, 80 microns, 90 microns, or 100 microns. In some embodiments, the thickness of the first plug wrap 7 is in the range of 40 microns to 120 microns, or in the range of 50 to 100 microns.

[0092] In some embodiments, the first plug wrap 7 is, for example, a non-porous plug wrap having a permeability of less than 100 cholesterol units, for example less than 50 cholesterol units. However, in other embodiments, the first plug wrap 7 can be, for example, a porous plug wrap having a permeability greater than 200 cholesterol units.

[0093] In some embodiments, the length of the material body 6 is shorter than about 20 mm. In this example, the length of the material body 6 is about 12 mm.

[0094] In some embodiments, the axial length of the material body 6 is in the range of 10 mm to 20 mm.

[0095] In some embodiments, the aerosol-forming material is applied to the material body 6. For example, the aerosol-forming material may be applied to the sheet material 6A before the sheet material 6A is folded to form the material body 6. The aerosol-forming material may be sprayed onto the sheet material 6A, or may be applied by a brush or by dipping the sheet material 6 into the aerosol-forming material.

[0096] In some embodiments, the aerosol-forming material may include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. For example, the aerosol-forming material can include triacetin and / or triethyl citrate.

[0097] In some embodiments, at least 0.02 mg of aerosol-forming material is applied to the material body per 1 mm of the axial length of the material body. In some embodiments, at least 0.03 mg, at least 0.04 mg, or at least 0.05 mg of aerosol-forming material is applied to the material body per 1 mm of the axial length of the material body.

[0098] In some embodiments, 0.5 mg or less of aerosol-forming material is applied to the material body per 1 mm of the axial length of the material body. In some embodiments, 0.4 mg or less or 0.3 mg or less of aerosol-forming material is applied to the material body per 1 mm of the axial length of the material body.

[0099] At least some of the aerosol-forming material mixes with the aerosol as the aerosol passes through the material body 6, helping to make the aerosol feel less dry in the user's mouth.

[0100] In some embodiments, the outer volume of the material body 6 is at least 115 mm 3 . In this example, the material body 6 is generally cylindrical and thus has a generally cylindrical outer volume. It should be recognized that in other embodiments, the outer volume of the material body 6 may be smaller than 115 mm 3 .

[0101] In this example, the width W1 of the material body 6 (which corresponds to the diameter of the material body 6 in this example) is approximately 6.36 mm, and the axial length L1 of the material body 6 is 12 mm. Therefore, the outer volume of the material body 6 is approximately 381 mm 3 is.

[0102] The material body 6A containing cellulose and having a volume of at least 115 mm 3 has been found to be useful for removing moisture from the aerosol generated by the aerosol generating material 3 when the aerosol passes through the material body 6A of the suction port 2. That is, the cellulose containing the sheet material 6A absorbs water from the aerosol. By removing moisture from the aerosol, the aerosol is felt colder in the user's mouth.

[0103] In some embodiments, the volume of the material body 6 is at least 19 mm per 1 mm of the axial length of the material body 3 , at least 25 mm per 1 mm of the axial length 3 , or at least 30 mm per 1 mm of the axial length 3 . For example, when the volume of the material body 6 is 19 mm per 1 mm of the axial length 3 and the length L1 is 10 mm, the volume of the material body is 190 mm 3 .

[0104] Generally, the larger the volume of the material body 6A, the greater the effect of removing moisture from the aerosol. In some examples, the outer volume of the material body 6 is at least 200 mm 3 , at least 300 mm 3 , at least 400 mm 3 , at least 500 mm 3 , at least 600 mm 3 , at least 700 mm 3 , at least 800 mm 3 , at least 900 mm 3 , or at least 1000 mm 3 .

[0105] In some embodiments, the axial length L1 of the material body 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, or at least 10 mm.

[0106] In some embodiments, the axial length L1 of the material body 6 ranges from 5 mm to 20 mm, from 6 mm to 15 mm, or from 8 mm to 14 mm.

[0107] In some embodiments, the width W1 of the material body 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, or at least 9 mm.

[0108] In some embodiments, the outer circumference of the material body 6 is at least 16 mm, at least 18 mm, at least 20 mm, at least 22 mm, at least 25 mm, or at least 26 mm.

[0109] In some embodiments, the pressure drop across the material body 6 is at least 2 mm of water column, at least 3 mm of water column, or at least 4 mm of water column. The pressure drop across the material body may be at least 5 mm of water column, at least 6 mm of water column, at least 7 mm of water column, at least 8 mm of water column, at least 9 mm of water column, at least 10 mm of water column, or at least 11 mm of water column.

[0110] In some embodiments, the pressure drop across the material body 6 is less than 30 mm of water column, less than 28 mm of water column, or less than 25 mm of water column.

[0111] [[ID=2,4]]In some embodiments, the pressure drop across the material body 6 is about 20 mm of water column, 23 mm of water column, or 28 mm of water column.

[0112] In some embodiments, the pressure drop across the material body is in the range of 10 mm to 30 mm of water column, or in the range of 15 mm to 25 mm of water column.

[0113] In some embodiments, the pressure drop across the material body 6 is at least 1.0 water column mm per 1 mm of the axial length of the material body 6. In some embodiments, the pressure drop across the material body 6 is at least 1.2 water column mm, 1.5 water column mm, or 1.8 water column mm per 1 mm of the axial length of the material body 6.

[0114] In some embodiments, the pressure drop across the material body 6 is less than 3.0 water column mm, 2.8 water column mm, or 2.6 water column mm per 1 mm of the axial length of the material body 6. In some embodiments, the pressure drop across the material body 6 is less than 2.5 water column mm, 2.4 water column mm, or 2.3 water column mm per 1 mm of the axial length of the material body 6.

[0115] In some embodiments, the pressure drop across the material body 6 is in the range of 1.5 water column mm to 2.5 water column mm per 1 mm of the axial length of the material body 6, or in the range of 1.6 to 2.4 mmWG per 1 mm of the axial length of the material body 6.

[0116] In some of the embodiments, the mass of the material body 6 is at least 50 mg, at least 60 mg, or at least 70 mg. It has been advantageously found that providing a material body 6 with a large mass results in a large amount of moisture being absorbed from the aerosol. In this example, the mass of the material body is about 75 mg.

[0117] In some of the embodiments, the mass of the material body 6 is less than 150 mg, less than 100 mg, less than 85 mg, or less than 80 mg.

[0118] In some embodiments, the weight of the material body 6 is at least 2 mg per 1 mm of the axial length of the material body. In some embodiments, the weight of the material body 6 is at least 3 mg per 1 mm of the axial length, or at least 4 mg per 1 mm of the axial length.

[0119] In this example, the weight of the material body 6 is about 6 mg per mm. That is, as in this example, when the axial length L1 of the material body 6 is 12 mm, the total mass of the material body 6 is about 74 mg.

[0120] In some embodiments, the material body 6 is a solid cylindrical material body.

[0121] In some embodiments, the hardness of the suction port 2 is in the range of about 80% to 95%, or in the range of about 85% to 90%. The hardness of the suction port 2 may be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%.

[0122] The hardness of the suction port 2 can be measured according to the following protocol. When referring to the hardness of a section herein, the hardness is such as determined by the following measurement process. The measurement may be performed using any suitable device such as the Borgwaldt Hardness Tester H10.

[0123] Hardness is defined as the ratio of the height h0 of the body under a defined load to the height h1 of the body and is described as a percentage of h0. Hardness can be expressed as follows. Hardness = (h1 / h0) × 100 For an individual body or a body included in a plurality of sections of the rod, the hardness measurement is performed at a location in the center of the longitudinal direction of the body.

[0124] Apply a predefined load to the body using a load bar. The length of the load bar should be extremely long compared to the sample to be measured. The body to be measured is conditioned according to ISO3402 for at least 48 hours before the hardness measurement and maintained under the environmental conditions according to ISO3402 during the measurement.

[0125] To perform the hardness measurement, the body is placed inside the Hardness Tester H10, a preload of 2 g is applied to the body, and after 1 second, the initial height h0 of the body under the 2 g preload is recorded. Then, the preload is removed, and a load bar loaded with a 150 g load is lowered onto the sample at a speed of 0.6 mm / second. After 5 seconds, the height h1 of the body under the 150 g load is measured.

[0126] The hardness of the mouthpiece is determined as the average hardness of at least 20 mouthpieces measured according to this protocol.

[0127] The hardness of the material body 6 surrounded by the first plug wrap 7 (hereinafter, collectively referred to as the "component" for determining hardness) may also be determined by carefully cutting the article to remove the material body 6 surrounded by the first plug wrap 7 and using the above protocol. The hardness of the component may be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%.

[0128] The expression "circularity" refers to the ratio of the cross-sectional shape of the article / component that matches a perfect circle. Circularity is calculated according to Equation 1 below.

[0129]

Equation

[0130] To determine the circularity of article 1, the maximum outer diameter "X" of the component is measured using a caliper, and the minimum outer diameter "Y" of the article is measured using a caliper (these diameters are perpendicular to the central axis of article 1). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of article 1, the higher the circularity, indicating that the cross-sectional shape of article 1 is closer to a perfect circle.

[0131] In some embodiments, the roundness of article 1 is at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, or at least 95%.

[0132] The hardness of the material body 6 surrounded by the first plug wrap 7 (hereinafter also referred to as a "component" for determining roundness) may also be determined using the above protocol by carefully cutting the article to remove the material body 6 surrounded by the first plug wrap 7.

[0133] To determine the roundness of the material body 6 surrounded by the first plug wrap 7 (hereinafter also referred to as a "component" for determining roundness), the maximum outer diameter "X" of the component is measured using a caliper, and the minimum outer diameter "Y" of the component is measured using a caliper (these diameters are perpendicular to the central axis of the component). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of the component, the higher the roundness, which indicates that the cross-sectional shape of the component is close to a perfect circle.

[0134] In some embodiments, the roundness of the component (i.e., the roundness of the material body 6 surrounded by the first plug wrap 7) is at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, or at least 95%.

[0135] If the roundness of the article / component is not high, the downstream part that is too elliptical will clog or be misaligned in the manufacturing machine. Therefore, the high roundness helps to ensure that the downstream part can be processed reliably.

[0136] The first plug wrap 7 and / or the second plug wrap 9 can be adhered around the component(s) of the article by an adhesive applied to a lap seam extending longitudinally along the first plug wrap and / or the second plug wrap. The first plug wrap 7 and / or the second plug wrap 9 can alternatively or additionally be adhered directly to the underlying component(s) using an adhesive. In both cases, the adhesive can be selected to be a water-soluble adhesive to aid in the disassembly of the component(s). Additionally or alternatively, the first plug wrap 7 and / or the second plug wrap 9 can themselves be formed from paper or other materials with improved degradability, such as other materials with improved dispersibility when exposed to water.

[0137] Biodegradability can be measured according to the procedure specified in ISO 14855. Components as described herein can achieve more than 50% biodegradation in 30 days when exposed to either fresh water or sea water.

[0138] In some embodiments, the length of the tubular portion 4a is less than about 50 mm. In some embodiments, the length of the tubular portion 4a is less than about 40 mm. In some embodiments, the length of the tubular portion 4a is less than about 35 mm. Additionally or alternatively, the length of the tubular portion 4a is at least about 10 mm. In some embodiments, the length of the tubular portion 4a is at least about 15 mm.

[0139] In some embodiments, the length of the tubular portion 4a is from about 15 mm to about 35 mm, from about 20 mm to about 30 mm, from about 23 to about 29 mm, or about 25 mm or about 29 mm. In this example, the length of the tubular portion 4a is 25 mm.

[0140] In some embodiments, the weight of the second plug wrap 9 is less than 50 gsm. In some embodiments, the weight of the second plug wrap 9 is about 20 gsm to 45 gsm. However, it should be recognized that the weight of the second plug wrap 9 may be greater to increase the hardness of the suction port. For example, the weight of the second plug wrap 9 may be at least 50 gsm, at least 60 gsm, at least 70 gsm, at least 80 gsm, at least 90 gsm, or at least 100 gsm. In some embodiments, the weight of the second plug wrap 9 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.

[0141] In some embodiments, the weight of the second plug wrap 9 is at least 10 gsm, at least 15 gsm, at least 20 gsm, or at least 25 gsm.

[0142] In some embodiments, the weight of the second plug wrap 9 is less than 40 gsm, less than 35 gsm, or less than 30 gsm.

[0143] In some embodiments, the weight of the second plug wrap 9 is in the range of 10 to 40 gsm, in the range of 15 to 35 gsm, in the range of 20 to 30 gsm, or in the range of 25 to 30 gsm. In some embodiments, the weight of the second plug wrap 9 is about 27 gsm.

[0144] In some embodiments, the thickness of the second plug wrap 9 is 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be recognized that the thickness of the second plug wrap 9 may be greater to increase the hardness of the suction port. In some embodiments, for example, the thickness of the second plug wrap 9 may be at least 40 microns, at least 50 microns, at least 60 microns, at least 70 microns, at least 80 microns, at least 90 microns, or at least 100 microns. In some embodiments, the thickness of the second plug wrap 9 is in the range of 40 microns to 120 microns, or in the range of 50 microns to 100 microns.

[0145] In some embodiments, the second plug wrap 9 is a non-porous plug wrap having a permeability of less than 100 cholesterol units, such as less than 50 cholesterol units. However, in alternative embodiments, the second plug wrap 9 can be a porous plug wrap having a permeability greater than, for example, 200 cholesterol units.

[0146] The tubular portion 4a is disposed around and defines a void that functions as a cooling segment within the suction mouth 2. The void provides a chamber through which the heated volatile components generated by the aerosol-forming material 3 flow. The tubular portion 4a is hollow to provide a chamber for storing the aerosol, yet has sufficient rigidity to withstand the axial compressive forces and bending moments that may occur during manufacture and when the article 1 is in use. The tubular portion 4a provides a physical spacing between the aerosol-forming material 3 and the material body 6. This physical spacing provided by the tubular portion 4a creates a thermal gradient along the length of the tubular portion 4a.

[0147] In some embodiments, the suction mouth 2 has a cavity with an internal volume greater than 450 mm 3 It has been found that the formation of the aerosol can be improved by providing at least this volume of cavity. Such a cavity size provides sufficient space within the suction mouth 2 to be able to cool the heated volatile components, and thus exposes the aerosol-forming material 3 to a higher temperature than would otherwise be possible (otherwise, the aerosol could be too hot). In this example, the cavity is formed by the tubular portion 4a, but in alternative configurations it can be formed within different portions of the suction mouth 2. In some embodiments, the suction mouth 2 has an internal volume greater than 500 mm 3 such as greater than 550 mm, for example, a cavity formed within the tubular portion 4a, thereby further improving the aerosol. In some embodiments, the internal cavity is about 550 mm 3 such as greater than 550 mm3 ~about 850 mm 3 、or about 600 mm 3 ~about 800 mm 3 and has a volume of. In this example, the volume of the internal cavity of the tubular portion 4a is about 762 mm 3 .

[0148] The tubular portion 4a can be configured to provide a temperature difference of at least 40 °C between the heated volatile component entering the first upstream end of the tubular portion 4a and the heated volatile component exiting the second downstream end of the tubular portion 4a. In some embodiments, the tubular portion 4a is configured to provide a temperature difference of at least 60 °C, at least 80 °C, or at least 100 °C between the heated volatile component entering the first upstream end of the tubular portion 4a and the heated volatile component exiting the second downstream end of the tubular portion 4a. This temperature difference across the length of the tubular portion 4a protects the temperature-sensitive material body 6 from the high temperature of the aerosol-forming material 3 when heated.

[0149] In an alternative article, the tubular portion 4a can be replaced with an alternative cooling element, for example, an element formed from a material body through which the aerosol can pass longitudinally and which also performs the function of cooling the aerosol.

[0150] The mouthpiece 2 of the article 1 comprises an upstream end 3a adjacent to the aerosol-forming substrate 3 and a downstream end 2b distal from the aerosol-forming substrate 3.

[0151] The pressure drop or pressure difference (also referred to as suction resistance) at the mouthpiece, for example at the portion of the article 1 downstream of the aerosol - generating material 3, is less than about 40 mm of water column. It has been found that due to such a pressure drop, a sufficient aerosol containing desirable compounds such as flavor compounds can pass through the mouthpiece 2 and reach the consumer. In some embodiments, the pressure drop at the mouthpiece 2 is less than about 20 mm of water column. In some embodiments, a mouthpiece 2 having a pressure drop of less than 15 mm of water column, for example about 6 mm of water column, about 10 mm of water column, or about 14 mm of water column, has been used to achieve particularly improved aerosols. Alternatively or in addition to this, the pressure drop of the mouthpiece can be at least 3 mm of water column, at least 4 mm of water column, or at least 5 mm of water column. In some embodiments, the pressure drop of the mouthpiece can be about 5 mm of water column to 20 mm of water column, or 5 mm of water column to 15 mm of water column. At these values, when the aerosol passes through the mouthpiece 2, the aerosol can be decelerated at the mouthpiece 2, and as a result, the temperature of the aerosol has time to decrease before reaching the downstream end 2b of the mouthpiece 2.

[0152] In this example, the aerosol - generating material 3 is wrapped in a wrapper 10. The wrapper 10 can be, for example, a wrapper of paper or foil - lined paper. In this example, the wrapper 10 is substantially air - impermeable. In an alternative embodiment, the wrapper 10 has a permeability of less than 100 Gurley units or less than 60 Gurley units. It has been found that using a low - permeability wrapper, for example a wrapper with a permeability of less than 100 Gurley units or less than 60 Gurley units, improves the formation of aerosols in the aerosol - generating material 3. Without wishing to be bound by theory, this is presumably due to a reduction in the loss of aerosol compounds through the wrapper 10. The permeability of the wrapper 10 can be measured according to ISO2965:2009 regarding the measurement of air permeability of materials used as cigarette paper, filter plug wrap, and filter tipping paper.

[0153] In this embodiment, the wrapper 10 includes an aluminum foil. The aluminum foil has been found to be particularly effective in enhancing the formation of the aerosol within the aerosol-forming material 3. In this example, the aluminum foil has a metal layer with a thickness of about 6 μm. In this example, the aluminum foil has a backing paper. However, in an alternative configuration, the aluminum foil can have other thicknesses, for example, a thickness of 4 μm to 16 μm. The aluminum foil also does not necessarily have a backing paper, but can have, for example, a backing formed from another material that helps to give the foil an appropriate tensile strength, or may not have a backing material. Metal layers or foils other than aluminum can also be used. The total thickness of the wrapper is 20 μm to 60 μm, or 30 μm to 50 μm, and with this thickness, the wrapper can have appropriate structural integrity and heat transfer characteristics. The tensile force that can be applied to the wrapper until it breaks can be a force greater than 3,000 grams, for example, a force of 3,000 to 10,000 grams, or a force of 3,000 to 4,500 grams.

[0154] In some examples, the wrapper 10 surrounding the aerosol-forming material 3 has a high level of permeability, for example, greater than about 1000 cst units, or greater than about 1500 cst units, or greater than about 2000 cst units. The permeability of the wrapper 10 can be measured in accordance with ISO2965:2009 regarding the measurement of the air permeability of the materials used as cigarette paper, filter plug wrap, and filter tipping paper.

[0155] The wrapper 10 may be formed from a material having a unique high level of permeability, an essentially porous material, or a material having any level of unique permeability, in which case the final permeability level is achieved by providing a wrapper 10 having a permeable area or region. By providing a permeable wrapper 10, a path for air to enter the article is created. The wrapper 10 can be configured to have a permeability such that the amount of air entering through the rod of the aerosol-forming material is relatively greater than the amount of air entering the article through the ventilation holes 12 of the mouthpiece. An article having this configuration can produce a more fragrant aerosol, which can better satisfy the user.

[0156] In this example, the aerosol-forming material added to the aerosol-generating substrate 3 constitutes 14% by weight of the aerosol-generating substrate 3. In some embodiments, the aerosol-forming material constitutes at least 5% by weight of the aerosol-generating substrate, or at least 10% by weight of the aerosol-generating substrate. In some embodiments, the aerosol-forming material constitutes less than 25% by weight of the aerosol-generating substrate, or less than 20% by weight, for example, 10% - 20%, 12% - 18%, or 13% - 16%.

[0157] In some embodiments, the aerosol-generating material 3 is provided as a cylindrical rod of the aerosol-generating material. Regardless of the form of the aerosol-generating material, the length can be about 10 mm to 100 mm. In some embodiments, the length of the aerosol-generating material is in the range of about 25 mm to 50 mm, in the range of about 30 mm to 45 mm, or in the range of about 30 mm to 40 mm.

[0158] In some examples, the article 1 may be configured such that there is a spacing (i.e., a minimum distance) between the heater of the non-combustible aerosol supply device 100 and the tubular body 4a. This prevents the heat of the heater from damaging the material forming the tubular body 4a.

[0159] The minimum distance between the heater of the non-combustible aerosol supply device 100 and the tubular body 4a may be about 3 mm or more. In some examples, the minimum distance between the heater of the non-combustible aerosol supply device 100 and the tubular body 4a may be in the range of 3 mm to 10 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0160] The spacing between the heater of the non-combustible aerosol supply device 100 and the tubular body 4a may be achieved, for example, by adjusting the length of the rod of the aerosol-forming material 3.

[0161] The volume of the aerosol-forming material 3 provided may be from about 200 mm 3 to about 4300 mm 3 , from about 500 mm 3 to 1500 mm 3 or from about 1000 mm 3 to about 1300 mm 3 and can be varied. It has been advantageously shown that by providing an aerosol-forming material in these volumes, for example from about 1000 mm 3 to about 1300 mm 3 excellent aerosols with better visibility and sensory performance are achieved compared to those achieved with volumes selected from the lower limit of this range.

[0162] The mass of the aerosol-forming material 3 provided can be greater than 200 mg and can be, for example, from about 200 mg to 400 mg, from about 230 mg to 360 mg, or from about 250 mg to 360 mg. It has been advantageously found that providing a larger mass of aerosol-forming material improves the sensory performance compared to aerosols generated from a smaller mass of tobacco material.

[0163] In some embodiments, the aerosol-forming material or substrate is formed from a tobacco material as described herein that contains tobacco components.

[0164] In the tobacco material described herein, the tobacco component may include recycled tobacco. The tobacco component may also include leaf tobacco, extruded tobacco, and / or bandcast tobacco.

[0165] The aerosol - generating material 3 can include a recycled tobacco material having a density lower than about 700 milligrams per cubic centimeter (700 mg / cc). Such tobacco materials have been found to be particularly effective in providing an aerosol - generating material that can be heated quickly to release an aerosol compared to higher - density materials. For example, the inventors tested the properties when heating various aerosol - generating materials such as bandcast recycled tobacco materials and paper - recycled tobacco materials. For each given aerosol - generating material, while heat is being applied to the material, below a certain temperature the net heat flow is endothermic, i.e., more heat enters the material than exits the material, and above that certain temperature the net heat flow is exothermic, i.e., more heat exits the material than enters the material. It has been found that there is a specific temperature at which the heat flow becomes zero. The temperature at which the heat flow becomes zero for materials with a density lower than 700 mg / cc was low. Since a significant portion of the heat flow out of the material is due to the formation of the aerosol, the low temperature at which the heat flow becomes zero has a beneficial effect on the time it takes for the aerosol to be first released from the aerosol - generating material. For example, it has been found that an aerosol - generating material with a density lower than 700 mg / cc has a temperature at which the heat flow becomes zero lower than 164°C compared to a material with a density exceeding 700 mg / cc (the temperature at which the heat flow becomes zero is higher than 164°C).

[0166] The density of the aerosol - generating material also affects the rate at which heat is conducted through the material. At a low density, for example, lower than 700 mg / cc, the rate of heat conduction through the material is slower, and thus the release of the aerosol can be sustained for a longer time.

[0167] The aerosol-generating material 3 may include a recycled tobacco material having a density lower than about 700 mg / cc, such as a paper-recycled tobacco material. In some embodiments, the aerosol-generating material 3 includes a recycled tobacco material having a density lower than about 600 mg / cc. Alternatively or in addition to this, the aerosol-generating material 3 may include a recycled tobacco material having a density of at least 350 mg / cc that is considered capable of transmitting a sufficient amount of heat through the material.

[0168] The tobacco material may be provided in the form of cut-rag tobacco. The cut-rag tobacco can have a cut width of at least 15 cuts per inch (equivalent to about 5.9 cuts per cm, a cut width of about 1.7 mm). In some embodiments, the cut-rag tobacco has a cut width of at least 18 cuts per inch (equivalent to about 7.1 cuts per cm, a cut width of about 1.4 mm), or at least 20 cuts per inch (equivalent to about 7.9 cuts per cm, a cut width of about 1.27 mm). In one example, the cut-rag tobacco has a cut width of 22 cuts per inch (equivalent to about 8.7 cuts per cm, a cut width of about 1.15 mm). The cut-rag tobacco may have a cut width with a number of cuts of 40 cuts per inch or less (equivalent to about 15.7 cuts per cm, a cut width of about 0.64 mm). It has been found that a cut width of 0.5 mm to 2.0 mm, such as 0.6 mm to 1.5 mm, or 0.6 mm to 1.7 mm, provides a tobacco material that is suitable with respect to the ratio of surface area to volume of the substrate 3, as well as the overall density and pressure drop, particularly when heated. The cut-rag tobacco can be formed from a mixture of forms of tobacco material, such as one or more mixtures of paper-recycled tobacco, leaf tobacco, extruded tobacco, and band-cast tobacco. In some embodiments, the tobacco material includes paper-recycled tobacco, or a mixture of paper-recycled tobacco and leaf tobacco.

[0169] In the tobacco materials described in this specification, the tobacco materials may contain a filler component. The filler component is generally a non-tobacco component, that is, a component that does not contain components derived from tobacco. The filler component may be a non-tobacco fiber such as wood fiber or pulp or wheat fiber. The filler component may also be an inorganic material such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate. The filler component may also be a non-tobacco cast material or a non-tobacco extrusion material. The filler component may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1 to 10% by weight of the composition. In some embodiments, the filler component is absent.

[0170] In the tobacco materials described herein, the tobacco material includes an aerosol-forming material. In this context, "aerosol-forming material" is an agent that promotes the generation of an aerosol. The aerosol-forming material can promote the generation of an aerosol by promoting the initial vaporization and / or the condensation of a gas into a drawable solid and / or liquid aerosol. In some embodiments, the aerosol-forming material can improve the delivery of flavor from the aerosol-generating material. Generally, any suitable aerosol-forming material or aerosol-forming agent may be included within the aerosol-generating material of the present invention, including those described herein. Other suitable aerosol-forming materials include, but are not limited to, polyols such as sorbitol, glycerol, and glycols such as propylene glycol or triethylene glycol, monohydric alcohols, non-polyols such as high-boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, or myristic acid including ethyl myristate and isopropyl myristate, and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate, and dimethyl tetradecanedioate. 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, such as 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.

[0171] The aerosol-forming material may be included in any component of the tobacco material, such as any tobacco component and / or (if any) filler component. Alternatively or in addition, the aerosol-forming material may be added separately to the tobacco material. In either case, the total amount of the aerosol-forming material in the tobacco material can be as defined herein.

[0172] The tobacco material can contain from 10% to 90% by weight of tobacco leaves, and the aerosol-forming material is provided with tobacco leaves in an amount of up to about 10% by weight. Advantageously, it has been found that this can be added in a higher weight percentage to another component of the tobacco material, such as a recycled tobacco material, so that the overall level of the aerosol-forming material is from 10% to 20% by weight of the tobacco material.

[0173] The tobacco material described herein contains nicotine. The nicotine content is from 0.5% to 1.75% by weight of the tobacco material, and can be, for example, from 0.8% to 1.5% by weight of the tobacco material. In addition or alternatively, the tobacco material contains from 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 advantageously found that using tobacco leaves having a nicotine content of more than 1.5% in combination with a lower nicotine base material such as paper-recycled tobacco results in a tobacco material having an appropriate nicotine level but better sensory performance than when using paper-recycled tobacco alone. Tobacco leaves, such as shredded tobacco, can have, for example, a nicotine content of from 1.5% to 5% by weight of the tobacco leaves.

[0174] The tobacco material described herein can contain an aerosol modifier such as any of the flavorings described herein. In one embodiment, the tobacco material contains menthol and forms a menthol-containing article. The tobacco material can contain from 3 mg to 20 mg of menthol, from 5 mg to 18 mg, or from 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol. The tobacco material can contain from 2% to 8% by weight of menthol, from 3% to 7% by weight of menthol, or from 4% to 5.5% by weight of menthol. In one embodiment, the tobacco material contains 4.7% by weight of menthol. Such a high level of menthol can be incorporated using a high proportion of recycled tobacco material, for example, a proportion of more than 50% by weight of the tobacco material. Alternatively or in addition, using a large amount of aerosol-generating material, such as the tobacco material, allows for a high level of menthol to be incorporated, for example, in this case, about 500 mm3 more, or preferably about 1000 mm 3 More aerosol - generating material such as tobacco material is used.

[0175] In the compositions described herein, when amounts are given in weight %, unless otherwise specifically indicated to the contrary, this refers to the dry weight to avoid misunderstanding. Thus, any water that may be present in the tobacco material or any component is completely ignored for the determination of weight %. The moisture content of the tobacco material described herein may vary, for example, it may be 5 - 15 wt%. The moisture content of the tobacco material described herein may vary, for example, according to the temperature, pressure, and humidity conditions under which the composition is maintained. The moisture content can be determined by Karl Fischer analysis, as is known to those skilled in the art. On the other hand, to avoid misunderstanding, even when the aerosol - forming material is a component in a liquid phase such as glycerol or propylene glycol, any component other than water is included in the weight of the tobacco material. However, when the aerosol - forming material is provided within the tobacco component of the tobacco material or within the filler component (if present) of the tobacco material, instead of or in addition to being added separately to the tobacco material, the aerosol - forming material is not included in the weight of the tobacco component or filler component, but is included in the weight of the "aerosol - forming material" at the weight % defined herein. All other components present in the tobacco component are included in the weight of the tobacco component, even if they are non - tobacco - derived (e.g., non - tobacco fibers in the case of recycled paper tobacco).

[0176] In one embodiment, the tobacco material comprises a tobacco component as defined herein and an aerosol - forming material as defined herein. In one embodiment, the tobacco material consists essentially of a tobacco component as defined herein and an aerosol - forming material as defined herein. In one embodiment, the tobacco material consists of a tobacco component as defined herein and an aerosol - forming material as defined herein.

[0177] The recycled paper tobacco is present in the tobacco component of the tobacco material described herein in an amount of 10% to 100% by weight of the tobacco component. In some embodiments, the recycled paper tobacco is present in an amount of 10% to 80% by weight, or 20% to 70% by weight, of the tobacco component. In further embodiments, the tobacco component consists essentially of or consists of the recycled paper tobacco. In some embodiments, the leaf tobacco is present in the tobacco component of the tobacco material in an amount of at least 10% by weight of the tobacco component. For example, the leaf tobacco can be present in an amount of at least 10% by weight of the tobacco component, while the remainder of the tobacco component includes a combination of recycled paper tobacco, reconstituted bandcast tobacco, or another form of tobacco such as reconstituted bandcast tobacco and tobacco granules.

[0178] Recycled paper tobacco refers to a tobacco material formed by a process in which tobacco raw materials are extracted with a solvent to form a soluble extract and a residue containing fibrous material, and then the extract (usually after concentration and optionally after further treatment) is recombined with the fibrous material from the residue (usually after purification of the fibrous material and optionally with the addition of a portion of non-tobacco fibers) by depositing the extract on the fibrous material. This recombination process is similar to the papermaking process.

[0179] The recycled paper tobacco can be any type of recycled paper tobacco known in the art. In certain embodiments, the recycled paper tobacco is made from raw materials including one or more of tobacco strips, tobacco stalks, and whole leaf tobacco. In further embodiments, the recycled paper tobacco is made from raw materials consisting of tobacco strips and / or whole leaf tobacco, and tobacco stalks. However, in other embodiments, fragments, fines, and husks can be used as raw materials instead of or in addition to this.

[0180] The recycled paper tobacco for use in the tobacco materials described herein may be prepared by methods known to those skilled in the art for preparing recycled paper tobacco.

[0181] In some embodiments, it is particularly advantageous to use a hollow tubular element 8 that is longer than about 10 mm, for example, having a length of about 10 mm to about 30 mm, or about 12 mm to about 25 mm. It has been found that a consumer's lip may, in some cases, extend up to about 12 mm from the mouth-side end of the article 1 when aspirating the aerosol through the article 1. Thus, the length of the hollow tubular element 8 being at least 10 mm or at least 12 mm means that most of the consumer's lip surrounds this element 8.

[0182] FIG. 3 is a side cross-sectional view of a further article 1' including a suction mouth 2' that includes a hollow tubular element 8. The suction mouth 2' is substantially the same as the suction mouth 2 described above in connection with FIG. 1, except that at the downstream end 2b, the suction mouth 2' includes a hollow tubular element 8 formed from a filament tow. In this example, the tubular portion 4a, the material body 6, and the hollow tubular element 8 are joined using a second plug wrap 9 wrapped around all three of these sections.

[0183] The material body 6 of the article 1' in FIG. 3 is the same as the material body 6 described above in connection with FIGS. 1 and 2. As described above, the material body 6 is manufactured from a sheet material that includes cellulose, and for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.

[0184] In this example, the axial length L1 of the material body 6 is about 10 mm. However, one skilled in the art will recognize that the axial length L1 of the material body 6 may be different. In some embodiments, the length L1 of the material body 6 is less than about 20 mm, or less than 15 mm. In some embodiments, the length L1 of the material body 6 is shorter than about 10 mm. In addition to or instead of this, the length L1 of the material body 6 may be at least about 5 mm. In some embodiments, the length L1 of the material body 6 is at least about 6 mm. In some embodiments, the length L1 of the material body 6 is from about 5 mm to about 15 mm, from about 6 mm to about 12 mm. In some embodiments, the length L1 of the material body is 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0185] The portion of the mouthpiece that contacts the consumer's lips is typically a paper tube, which is either hollow or surrounds a cylindrical body of filter material. It has advantageously been found that providing the hollow tubular element 8 significantly reduces the temperature of the outer surface of the mouthpiece 2' at the downstream end 2b of the mouthpiece that contacts the consumer's mouth during use of the article 1'. Additionally, the use of the tubular portion 4a has also been found to significantly reduce the temperature of the outer surface of the mouthpiece 2', even upstream of the tubular portion 4a. Without wishing to be bound by theory, this is assumed to be due to the tubular portion 4a directing the aerosol closer to the center of the mouthpiece 2', thus reducing the transfer of heat from the aerosol to the outer surface of the mouthpiece 2'. Additionally, the material body 6 has been found to remove moisture from the aerosol generated by the aerosol-generating material 3 as the aerosol passes through the material body 6A of the mouthpiece 2, which makes the user feel the aerosol as cooler in the mouth.

[0186] In this example, the hollow tubular element 8 is formed from a filament tow. In alternative embodiments, the hollow tubular element may be formed using any structure as described herein with respect to the tubular portion 4a.

[0187] The "wall thickness" of the hollow tubular element 8 corresponds to the thickness of the wall in the radial direction of the tube 8. This can be measured in the same way as the wall thickness of the tubular portion. It is advantageous for the wall thickness to be greater than 0.9 mm and it may be 1.0 mm or more. In some embodiments, the wall thickness is substantially constant throughout the wall of the hollow tubular element 8. However, if the wall thickness is not substantially constant, the wall thickness may be greater than 0.9 mm, for example 1.0 mm or more, at any point around the hollow tubular element 8.

[0188] The length of the hollow tubular element 8 is shorter than about 20 mm. In some embodiments, the length of the hollow tubular element 8 is shorter than about 15 mm. In some embodiments, the length of the hollow tubular element 8 is shorter than about 10 mm. In addition to or instead of this, the length of the hollow tubular element 8 may be at least about 5 mm. In some embodiments, the length of the hollow tubular element 8 is at least about 6 mm. In some embodiments, the length of the hollow tubular element 8 is from about 5 mm to about 20 mm, from about 6 mm to about 10 mm, or from about 6 mm to about 8 mm. In some embodiments, the length of the hollow tubular element 8 is 6 mm, 7 mm, or 8 mm. In this example, the length of the hollow tubular element 8 is 6 mm.

[0189] The density of the hollow tubular element 8 is at least about 0.25 grams per cubic centimeter (0.25 g / cc), for example at least about 0.3 g / cc. In some embodiments, the density of the hollow tubular element 8 is less than about 0.75 grams per cubic centimeter (0.75 g / cc), for example less than 0.6 g / cc. In some embodiments, the density of the hollow tubular element 8 is from 0.25 g / cc to 0.75 g / cc, from 0.3 g / cc to 0.6 g / cc, or from 0.4 g / cc to 0.6 g / cc. In some embodiments, the density of the hollow tubular element 8 is about 0.5 g / cc. These densities have been found to provide a good balance between the improved stiffness provided by the higher density material and the lower heat transfer properties of the lower density material. For the purposes of the present invention, the "density" of the hollow tubular element 8 refers to the density of the filament tow forming the element with any plasticizer incorporated. The density can be determined by dividing the total weight of the hollow tubular element 8 by the total volume of the hollow tubular element 8, and the total volume can be calculated using, for example, appropriate measurements of the hollow tubular element 8 taken using calipers. If necessary, appropriate dimensions may be measured using a microscope.

[0190] The total fineness of the filament tow forming the hollow tubular element 8 may be less than 45,000 denier, for example, less than 42,000 denier. It has been found that with this total fineness, a hollow tubular element 8 with a density that is not too high can be formed. In some embodiments, the total fineness is at least 20,000 denier, for example, at least 25,000 denier. In some embodiments, the total fineness of the filament tow forming the hollow tubular element 8 is 25,000 to 45,000 denier, for example, 35,000 to 45,000 denier. In some embodiments, the cross-sectional shape of the filaments of the tow is a "Y" shape, but in other embodiments, filaments with other cross-sectional shapes such as an "X" shape can be used.

[0191] The filament tow forming the hollow tubular element 8 may be thicker than 3 denier per filament. It has been found that with this fineness per filament, a hollow tubular element 8 with a density that is not too high can be formed. In some embodiments, the fineness per filament is at least 4 denier, for example, at least 5 denier. In some embodiments, the filament tow forming the hollow tubular element 8 is 4 to 10 denier per filament, for example, 4 to 9 denier. In one example, the filament tow forming the hollow tubular element 8 is formed from cellulose acetate and has an 8Y40,000 tow containing 18% plasticizer, for example, triacetin.

[0192] The inner diameter of the hollow tubular element 8 may be greater than 3.0 mm. A smaller diameter than this increases the speed of the aerosol reaching the consumer's mouth through the suction port 2' to a speed higher than the desired speed, and as a result, the aerosol may become too warm, for example, reach a temperature higher than 40°C or higher than 45°C. In some embodiments, the inner diameter of the hollow tubular element 8 is greater than 3.1 mm, for example, greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular element 8 is about 3.9 mm.

[0193] In some embodiments, the hollow tubular element 8 contains 15% to 22% by weight of a plasticizer. For cellulose acetate tow, the plasticizer may be triacetin, but other plasticizers such as polyethylene glycol (PEG) can be used. In some embodiments, the hollow tubular element 8 contains 16% to 20% by weight of a plasticizer, such as about 17%, about 18%, or about 19% by weight of the plasticizer.

[0194] In this example, the tubular portion 4a is the first hollow tubular element, and the hollow tubular element 8 is the second hollow tubular element.

[0195] In this example, the ventilation is supplied into the tubular portion 4a as described in connection with FIG. 1. In an alternative embodiment, the ventilation can be supplied at other locations into the suction port, for example, within the material body 6 or within the hollow tubular element 8.

[0196] In the above example, the suction ports 2, 2' each comprise a single material body 6. In other examples, the suction ports 2, 2' may include a plurality of material bodies. The suction ports 2, 2' may have a cavity between the material bodies.

[0197] In some examples, the mouths 2, 2' downstream of the aerosol-generating material 3 can comprise a wrapper containing an aerosol modifier as described herein, or other sensory material, such as the first plug wrapper 7 or the second plug wrapper 9, or the tip paper 5. The aerosol modifier may be disposed on a surface facing the inside or the outside of the wrapper of the mouth. For example, the aerosol modifier or other sensory material may be provided in an area of the wrapper that contacts the consumer's lips during use, such as a surface facing the outside of the tip paper 5. By disposing the aerosol modifier or other sensory material on the surface facing the outside of the wrapper of the mouth, the aerosol modifier or other sensory material may be transmitted to the consumer's lips during use. Transmitting the aerosol modifier or other sensory material to the consumer's lips during use of the article can change the sensory acceptance characteristics (e.g., taste) of the aerosol generated by the aerosol-generating substrate 3, or, alternatively, provide the consumer with an alternative perceptual experience. For example, the aerosol modifier or other sensory material may impart a flavor to the aerosol generated by the aerosol-generating substrate 3. The aerosol modifier or other sensory material may be at least partially water-soluble so as to be transmitted to the user by the consumer's saliva. The aerosol modifier or other sensory material may be volatile by heat generated by the aerosol supply system. Thereby, it is possible to facilitate the transmission of the aerosol modifier to the aerosol generated by the aerosol-generating substrate 3. Suitable sensory materials may be fragrances, sucralose, or cooling agents such as menthol as described herein.

[0198] In some embodiments (not shown), the mouths 2, 2' may comprise an aerosol modifier release component operable to release an aerosol modifier. In some embodiments, the aerosol modifier release component may be operable to selectively release the aerosol modifier. As discussed above, the material body 6 can comprise fibers in the range of 2 mm to 6 mm in length, such that when the aerosol modifier is released from the aerosol modifier release component, the material body 6 does not absorb the particular aerosol modifier very much.

[0199] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of 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 in the form of a powder, a thread, or a granule. The aerosol modifier may not have a filter material.

[0200] The aerosol modifier release component may be, for example, a capsule, a thread, or a bead. In some embodiments, a plurality of aerosol modifier release components are provided, and may include a plurality of charcoal particles containing the aerosol modifier.

[0201] In some embodiments, the aerosol modifier release component includes a thread containing an additive. The thread may be made of, for example, cellulose acetate or cotton fibers.

[0202] In some embodiments, the aerosol modifier release component has an aerosol modifier in the range of 1 mg to 20 mg, for example, an aerosol modifier in the range of 2 mg to 15 mg.

[0203] The aerosol modifier release component, for example, a capsule, may be disposed within the body 6. This aerosol modifier release component or each aerosol modifier release component may be combined with a sheet material 6A, and for example, may be adhered to the sheet material 6A before the sheet material 6A is formed on the body 6.

[0204] In some embodiments, there is provided a non-combustible aerosol supply system comprising an aerosol modifier release component and a heater operable to heat an aerosol generating material 3 so that the aerosol generating material 3 supplies an aerosol during use.

[0205] The aerosol modifier release component may comprise a capsule. In some embodiments, the aerosol modifier release component comprises a first capsule and a second capsule. The first capsule is disposed in a first portion of the aerosol modifier release component, and the second capsule is disposed in a second portion of the aerosol modifier release component downstream of the first portion.

[0206] The first portion of the aerosol modifier release component is heated to a first temperature during operation of the heater to generate an aerosol, and the second portion is heated to a second temperature during operation of the heater to generate an aerosol, and the second temperature is at least 4 °C lower than the first temperature. In some embodiments, the second temperature is at least 5, 6, 7, 8, 9, or 10 °C lower than the first temperature.

[0207] The aerosol modifier release component may constitute one or more components of article 1. In some embodiments, the first capsule and the second capsule are disposed in the material body 6. In one embodiment, the aerosol modifier release component includes two material bodies (not shown), the first capsule is disposed in the first material body, and the second capsule is disposed in the second body respectively. In some embodiments, the aerosol modifier release component instead of or in addition to this, comprises one or more tubular elements upstream and / or downstream of one or more material bodies. The aerosol generating component may comprise suction ports 2, 2'.

[0208] In some embodiments, the second capsule is disposed at a distance of at least 7 mm (measured as the distance between the center of the first capsule and the center of the second capsule) from the first capsule. In some embodiments, the second capsule is disposed at a distance of at least 8 mm, 9 mm, or 10 mm from the first capsule. It has been found that increasing the distance between the first capsule and the second capsule increases the difference between the first temperature and the second temperature.

[0209] The first capsule contains an aerosol modifier. The second capsule contains an aerosol modifier that may be the same as or different from the aerosol modifier of the first capsule. In some embodiments, the user can selectively rupture the first and second capsules by applying an external force to the aerosol modifier release component to release the aerosol modifier from each capsule.

[0210] The aerosol modifier of the second capsule is heated to a lower temperature than the aerosol modifier of the first capsule due to the difference between the first temperature and the second temperature.

[0211] The aerosol modifiers of the first and second capsules can be selected based on this temperature difference. For example, the first capsule may contain a first aerosol modifier with a lower vapor pressure than the second aerosol modifier of the second capsule. When both capsules are heated to the same temperature, the fact that the vapor pressure of the aerosol modifier of the second capsule is higher means that a larger amount of the second aerosol modifier is volatilized than the aerosol modifier of the first capsule. However, since the second capsule is heated to a lower temperature, this effect is not as significant, and when the first and second capsules are each destroyed, the aerosol modifiers of the first and second capsules are volatilized in a more uniform amount.

[0212] In some embodiments, the first capsule and the second capsule have the same aerosol modification profile, which means that both capsules contain the same type of aerosol modifier in the same amount, such that if both capsules are heated to the same temperature and destroyed, both capsules cause the same modification of the aerosol. However, since the first capsule is heated to a higher temperature than the second capsule, for example, more of the aerosol modifier in the first capsule is volatilized compared to the modifier in the second capsule, and thus causes a more significant modification of the aerosol than the second capsule. Thus, even though both capsules are the same (thereby allowing for easier and / or less expensive manufacture of the aerosol modifier release component), the user can decide whether to destroy the first capsule to cause a more significant modification of the aerosol, or the second capsule to cause a less significant modification of the aerosol, or both capsules to cause the maximum modification of the aerosol.

[0213] In some embodiments, both the first capsule and the second capsule contain a first aerosol modifier and a second aerosol modifier. The vapor pressure of the first aerosol modifier is lower than the vapor pressure of the second aerosol modifier. Thus, when the system is used to generate an aerosol, a greater proportion of the second aerosol modifier vaporizes when the second capsule is destroyed compared to when the hotter first capsule is destroyed. Thus, different modifications of the aerosol can be caused using the same capsules, based on the location of the capsules in the first or second part of the aerosol modifier release component.

[0214] In some embodiments, this capsule or each capsule comprises an outer shell and an inner core.

[0215] The shell of each capsule may be solid at room temperature. The shell may contain alginate, may consist of alginate, or may consist essentially of alginate. However, in alternative embodiments, it should be recognized that the shell is formed from a different material. For example, the shell may instead contain, consist of, or consist essentially of gelatin, carrageenan, or pectin. The shell may contain one or more of alginate, gelatin, carrageenan, or pectin, may consist of one or more of these, or may consist essentially of one or more of these.

[0216] The shell of each additive capsule may be impermeable or substantially impermeable to the core aerosol modifier. Thus, the shell initially prevents the core modifier from leaking out of the capsule. When the user wishes to modify the aerosol, the shell of the capsule is crushed so that the modifier is released.

[0217] In some embodiments (not shown), this capsule (or each capsule) further comprises a carrier material. The carrier material may contain, for example, gelatin.

[0218] In some embodiments, the diameter of this capsule (or each capsule) is in the range of 1 mm to 5 mm, or in the range of 2 mm to 4 mm. In some embodiments, the diameter of this capsule (or each capsule) is about 3 mm. This capsule (or each capsule) may generally be spherical. In other examples, capsules of other shapes and sizes may be used.

[0219] The total weight of each capsule may be in the range of about 5 mg to about 50 mg, or in the range of about 10 mg to about 30 mg. In some embodiments, the weight of each capsule is about 14 mg.

[0220] In some embodiments, one or more aerosol modifier release components are included within the material body 6, which is formed from a sheet material having a weight of less than 40 gsm, for example less than 35 or 30 gsm. This helps to reduce the density of the material body 6 in order to offset the presence of the aerosol modifier release components within the body 6 (otherwise the body 6 could become too rigid).

[0221] In some embodiments, one or more aerosol modifier release components are included within the material body 6, which is formed from a sheet material having a width of less than 100 mm, for example less than 90 mm or 80 mm. This helps to reduce the density of the material body 6 in order to offset the presence of the aerosol modifier release components within the body 6 (otherwise the body 6 could become too rigid).

[0222] In some embodiments, this capsule (or each capsule) is disposed at the center of the longitudinal axis of the mouthpiece 2.

[0223] As discussed above, this capsule (or each capsule) may have a core - shell structure. That is, the encapsulating material or barrier material creates a shell around a core that comprises the aerosol modifier. The shell structure prevents the aerosol modifier from migrating during storage of the article, but allows for a controlled release of the aerosol modifier, also referred to as an aerosol denaturant, during use.

[0224] In some cases, the barrier material (also referred to herein as the encapsulation material) is fragile. This capsule (or each capsule) is crushed, damaged, or broken by the user to release the encapsulated aerosol modifier. Typically, one or more of the capsules are broken just before heating is initiated, but the user can choose when to release the aerosol modifier from the capsule. The user can then later choose to break other capsules, for example, after heating has been initiated. The user can choose to break the other capsule when a portion of the aerosol is released from the aerosol-generating material, such that the remaining aerosol-generating material is modified by the aerosol modifier of the other capsule. Alternatively, the user may choose to break multiple capsules simultaneously.

[0225] The term "breakable capsule" refers to a capsule that can be broken under pressure to release the core, and more particularly, a capsule that can be ruptured by the pressure applied by the user's finger when the user desires to release the core of the capsule.

[0226] In some cases, the barrier material is heat-resistant. That is, in some cases, the barrier does not rupture, melt, or otherwise cease to function at the temperature reached at the location of the capsule during operation of the aerosol supply device. Exemplarily, a capsule disposed at the mouthpiece may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material can continue to hold the liquid core up to at least about 50°C to 120°C.

[0227] In other cases, this capsule (or each capsule) releases the core composition upon heating, for example, by melting of the barrier material or by expansion of the capsule that causes rupture of the barrier material.

[0228] The total weight of each capsule may range from about 1 mg to about 100 mg, from about 5 mg to about 60 mg, from about 8 mg to about 50 mg, from about 10 mg to about 20 mg, or from about 12 mg to about 18 mg.

[0229] The total weight of the core formulation may range from about 2 mg to about 90 mg, from about 3 mg to about 70 mg, from about 5 mg to about 25 mg, from about 8 mg to about 20 mg, or from about 10 mg to about 15 mg.

[0230] In some embodiments, this capsule (or each capsule) comprises the core and shell described above. Each capsule may exhibit a crushing strength of from about 4.5 N to about 40 N, from about 5 N to about 30 N, or from about 5 N to about 28 N (e.g., from about 9.8 N to about 24.5 N). The capsule rupture strength of each capsule can be measured by removing the capsule from the material body 6 and using a force gauge to measure the force at which the capsule ruptures when pressed between two flat metal plates. A suitable measuring device is the Sauter FK50 force gauge having a flat attachment part at the head, which can be used to press and crush the capsule against a flat hard surface having a surface similar to the attachment part.

[0231] This capsule (or each capsule) may be substantially spherical and the diameter may be at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm, or 3.0 mm. The diameter of this capsule (or each capsule) may be less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5 mm, 5.0 mm, 4.5 mm, 4.0 mm, 3.5 mm, or 3.2 mm. Exemplarily, the diameter of the capsule may range from about 0.4 mm to about 10.0 mm, from about 0.8 mm to about 6.0 mm, from about 2.5 mm to about 5.5 mm, or from about 2.8 mm to about 3.2 mm. In some cases, the diameter of this capsule (or each capsule) may be about 3.0 mm. These sizes are particularly suitable for incorporating the capsules into the articles described herein.

[0232] In some embodiments, the cross-sectional area of each capsule at the position of its maximum cross-sectional area is less than 28% of the cross-sectional area of the portion of the suction port 2 where the capsule is provided, for example, less than 27%, or less than 25%. For example, for a spherical capsule with a diameter of 3.0 mm, the maximum cross-sectional area of the capsule is 7.07 mm 2 is. In the suction port with an outer circumference of 21 mm described in this specification, the outer circumference of the material body 6 is 20.8 mm, and the radius of this component is 3.31 mm, which is 34.43 mm 2 corresponds to the cross-sectional area of. The cross-sectional area of the capsule is 20.5% of the cross-sectional area of the suction port 2 in this example. As another example, when the diameter of the capsule is 3.2 mm, its maximum cross-sectional area is 8.04 mm 2 becomes. In this case, the cross-sectional area of the capsule is 23.4% of the cross-sectional area of the material body 6. A capsule having a maximum cross-sectional area less than 28% of the cross-sectional area of the portion of the suction port 2 where the capsule is provided has a reduced pressure drop at the suction port 2 compared to a capsule having a larger cross-sectional area, and when the aerosol passes through the suction port 2, there is an advantage that sufficient space remains for the aerosol to pass around the capsule without the material body 6 removing a large amount of aerosol mass. In some embodiments, a first capsule and a second capsule are provided, and these may be of the same size or different sizes.

[0233] Figure 4 is a side cross-sectional view of a further article 1'' including a suction port 2''. The suction port 2'' is substantially the same as the suction port 2 described above in connection with FIGS. 1 and 2. The difference is that the material body 6 of the article 1'' is arranged upstream of the tubular portion 4a.

[0234] In this example, the tubular portion 4a and the material body 6 are joined using a second plug wrap 9 wrapped around the circumference of both sections.

[0235] The material body 6 of the article 1'' in FIG. 4 is the same as the material body 6 described above in connection with FIGS. 1 to 3. As described above, the material body 6 is manufactured from a sheet material containing cellulose, and for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.

[0236] The material body 6 is disposed at the upstream end 2a of the suction port 2'. The material body 6 is adjacent to the aerosol-generating material 3.

[0237] The tubular portion 4a is disposed at the downstream end 2b of the suction port 2'', and thus forms a cavity at the downstream end 2b. The tubular portion 4a is disposed downstream of the material body 6. In this example, the tubular portion 4a is directly adjacent to the material body 6.

[0238] The axial length L2 of the tubular portion 4a is at least 20 mm, for example at least 22 mm. In this example, the axial length L2 of the tubular portion 4a is about 25 mm.

[0239] It has been found that when the axial length L2 of the tube is at least 20 mm, the aerosol is significantly cooled as it passes through the tubular portion 4a. In addition, as described above, the cellulose including the sheet material of the material body 6 absorbs water from the aerosol. Removing moisture from the aerosol makes the user feel the aerosol cold in the mouth.

[0240] In some embodiments, the tubular portion 4a comprises one or more ventilation holes, which also contribute to the cooling of the aerosol.

[0241] In some embodiments, the tubular portion 4a is made of paper.

[0242] FIG. 5 is a side cross-sectional view of a further article 1''' including a suction port 2'''. The suction port 2''' is substantially the same as the suction port 2 described above in relation to FIGS. 1 and 2. The difference is that the suction port 2''' further comprises a tubular element 20 disposed within the material body 6.

[0243] In this example, the tubular portion 4a and the material body 6 are joined using a second plug wrap 9 wrapped around the circumference of both sections.

[0244] The material body 6 of the article 1''' in FIG. 5 is the same as the material body 6 described above in relation to FIGS. 1-3. As described above, the material body 6 is manufactured from a sheet material containing cellulose, and for example, the sheet material may be paper. The sheet material is pleated to form the material body 6.

[0245] The tubular element 20 may be, for example, a paper or plastic tube disposed within the material body 6. The tubular element 20 forms a cavity 21 within the material body 6. Optionally, the tubular element 20 is disposed substantially radially centrally within the material body 6.

[0246] In this example, the cavity 21 extends to the downstream end 2b of the suction port 2'''.

[0247] In this example, the axial length L1 of the material body 6 is about 10 mm. However, those skilled in the art will recognize that the axial length L1 of the material body 6 may be different. In some embodiments, the length L1 of the material body 6 is less than about 15 mm. In some embodiments, the length L1 of the material body 6 is less than about 10 mm. In addition to or instead of this, the length L1 of the material body 6 may be at least about 5 mm. In some embodiments, the length L1 of the material body 6 is at least about 6 mm. In some embodiments, the length L1 of the material body 6 is from about 5 mm to about 15 mm, from about 6 mm to about 12 mm, or from about 6 mm to about 12 mm. In some embodiments, the length L1 of the material body 6 is 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0248] In some embodiments, the axial length L3 of the tubular element 20 is at least 4 mm, for example about 5 mm.

[0249] The cavity 21 has been found to promote the cooling of the aerosol. The portion 6b of the material body 6 surrounding the tubular element 21 has been found to effectively insulate the user's lips from the heat of the aerosol. For example, in an embodiment where the material body 6 is manufactured from a sheet material disposed within the material body, it is believed that multiple layers of the sheet material of the material body 6 serve to insulate the user's lips from the heat of the aerosol. In some embodiments, optionally, there may be gaps, such as voids, between the layers of the sheet material that contribute to the insulating effect.

[0250] Also, the material body 6 may be more readily biodegradable than a structure in which a tubular portion of cellulose acetate is provided at the downstream end 2b of the mouthpiece instead.

[0251] As shown in FIG. 6, the material body 6 may be manufactured from a plurality of lengths of rods 22, four lengths of rods in this example. The rods are cut along line C-C to form individual material bodies 6 each comprising a tubular element 20 having a corresponding cavity 21.

[0252] The non-combustible aerosol supply device is used to heat the aerosol-generating material 3 of any of the articles 1, 1', 1'', 1''' described herein. The non-combustible aerosol supply device may comprise a coil, which has been found to be able to improve heat transfer to the articles 1, 1', 1'', 1''' compared to other configurations.

[0253] In some examples, the coil is configured to cause heating of at least one conductive heating element during use, such that thermal energy is conductable from the at least one conductive heating element to the aerosol-generating material, thereby causing heating of the aerosol-generating material.

[0254] In some examples, the coil is configured to generate a varying magnetic field that, during use, penetrates at least one heating element, thereby causing inductive heating and / or magnetic hysteresis heating of the at least one heating element. In such configurations, this heating element or each heating element may be referred to as a "susceptor" as defined herein. A coil configured to generate a varying magnetic field that, during use, penetrates at least one conductive heating element, thereby causing inductive heating of the at least one conductive heating element, may be referred to as an "inductive coil" or "inductor coil".

[0255] The device may include a heating element(s), such as a conductive heating element(s), and the heating element(s) may be suitably positioned relative to, or positionable relative to, the coil so as to enable such heating of the heating element(s). The heating element(s) may be in a fixed position relative to the coil. Alternatively, at least one heating element, such as at least one conductive heating element, may be included in articles 1, 1', 1'', 1''' for insertion into the heating section of the device, which articles 1, 1', 1'', 1''' also comprise an aerosol-forming material 3 and are removable from the heating section after use. Alternatively, both the device and such articles 1, 1', 1'', 1''' may each comprise at least one heating element, such as at least one conductive heating element, and the coil may be such as to cause heating of the respective heating element(s) of the device and the article when the article is within the heating section.

[0256] In some examples, the coil is helical. In some examples, the coil surrounds at least a portion of the heating section of a device configured to receive an aerosol-forming material. In some examples, the coil is a helical coil that surrounds at least a portion of the heating section.

[0257] In some examples, the device comprises a conductive heating element that at least partially surrounds a heating zone, and the coil is a helical coil that surrounds 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.

[0258] In some examples, by using the coil, a non-combustible aerosol supply device can reach the operating temperature faster than an aerosol supply device without a coil. For example, a non-combustible aerosol supply device including a coil as described above can reach the operating temperature such that the initial puff can be provided in less than 30 seconds, more preferably less than 25 seconds, from the start of the device heating program. In some examples, the device can reach the operating temperature in about 20 seconds from the start of the device heating program.

[0259] Using a coil as described herein in a device to cause heating of an aerosol - generating material has been found to improve the aerosol produced. For example, consumers have reported that the aerosol produced by a device containing a coil as described herein is more sensorily similar to a factory - made cigarette (FMC) product than the aerosol produced by other non - combustible aerosol delivery systems. Without wishing to be bound by theory, this is presumably because when a coil is used, the time to reach the required heating temperature is reduced, a higher heating temperature can be achieved when a coil is used, and / or the coil can heat a relatively large amount of aerosol - generating material simultaneously in such a system, resulting in an aerosol temperature similar to that of an FMC. In an FMC product, when the aerosol is drawn through the rod, the burning tip generates a hot aerosol that heats the tobacco within the tobacco rod behind the tip. This hot aerosol is understood to release flavor compounds from the tobacco within the rod behind the burning tip. A device containing a coil as described herein can also heat an aerosol - generating material, such as the tobacco material described herein, to release flavor compounds, resulting in an aerosol that is reported to be more similar to an FMC aerosol. Specific improvements in the aerosol can be achieved by using a device containing a coil to heat an article comprising a rod of aerosol - generating material having an outer perimeter longer than 19 mm, for example, an outer perimeter of about 19 mm to about 23 mm.

[0260] When using an aerosol supply system that includes a coil as described herein, for example, an induction coil that heats at least a portion of an aerosol-forming material to at least 200 °C, more preferably at least 220 °C, an aerosol can be generated from the aerosol-forming material that has certain characteristics that are considered to be similar to those of the aerosol of an FMC product. For example, when using an induction heater to heat an aerosol-forming material containing nicotine to at least 250 °C for 2 seconds under an air flow of at least 1.50 L / m, one or more of the following characteristics were observed. At least 10 μg of nicotine is aerosolized from the aerosol-forming material The weight ratio of the aerosol-forming material to 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 can be aerosolized from the aerosol-forming material The average particle size or droplet diameter of the generated aerosol is less than about 1000 nm The density of the aerosol is at least 0.1 μg / cc In some cases, at least 10 μg of nicotine, preferably at least 30 μg or 40 μg of nicotine, is aerosolized from the aerosol-forming material under an air flow of at least 1.50 L / m during that period. In some cases, less than about 200 μg, preferably less than about 150 μg or less than about 125 μg of nicotine is aerosolized from the aerosol-forming material under an air flow of at least 1.50 L / m during that period.

[0261] In some cases, the aerosol contains at least 100 μg of aerosol-forming material, preferably at least 200 μg, 500 μg, or 1 mg of aerosol-forming material is aerosolized from the aerosol-forming material under an air flow of at least 1.50 L / m during that period. Preferably, the aerosol-forming material may contain or consist of glycerol.

[0262] As defined herein, the term "average particle size or droplet size" refers to the average size of the solid or liquid components of the aerosol (i.e., the components suspended in the gas). When the aerosol contains suspended droplets and suspended solid particles, this term refers to the average size of all components combined.

[0263] In some cases, the average particle size or droplet size of the generated aerosol may be less than about 900 nm, less than 800 nm, less than 700 nm, less than 600 nm, less than 500 nm, less than 450 nm, or less than 400 nm. In some cases, the average particle size or droplet size may be greater than about 25 nm, 50 nm, or 100 nm.

[0264] In some cases, the aerosol density generated during this period is 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 less than about 2.5 μg / cc, less than 2.0 μg / cc, less than 1.5 μg / cc, or less than 1.0 μg / cc.

[0265] The non-combustible aerosol supply device may be configured to heat the aerosol-forming material 3 of articles 1, 1', 1'', 1''' to a maximum temperature of at least 160°C. In some embodiments, the non-combustible aerosol supply device is configured to heat the aerosol-forming material 3 of articles 1, 1', 1'', 1''' to a maximum temperature of at least about 200°C, or at least about 220°C, at least about 240°C, or at least about 270°C at least once during the heating process following the non-combustible aerosol supply device.

[0266] Using an aerosol supply system as described herein that includes a coil, for example, an induction coil that heats at least a portion of the aerosol-forming material to at least 200°C or at least 220°C.

[0267] In some embodiments, the temperature of the aerosol exiting the mouth-side ends of the suction ports 2, 2’, 2’’, 2’’’ is lower than 50°C, for example lower than 45°C.

[0268] Figure 7 shows an example of a non-combustible aerosol supply device 100 for generating an aerosol from an aerosol-generating medium / material such as the aerosol-generating material 3 of any of the articles 1, 1’, 1’’, 1’’’ described herein. Briefly, the device 100 comprises a replaceable article 110 comprising an aerosol-generating material, for example the articles 1, 1’, 1’’, 1’’’ described herein, which can be heated to generate an aerosol or other inhalable medium to be inhaled by a user of the device 100. The device 100 and the replaceable article 110 together form a system.

[0269] The device 100 comprises a housing 102 (in the form of an outer cover) that encloses and houses the various components of the device 100. The device 100 has an opening 104 at one end, and the article 110 can be inserted through the opening 104 for heating by a heating assembly. In use, the article 110 can be fully or partially inserted into the heating assembly and heated by one or more components of the heater assembly.

[0270] When the article 110 is inserted into the device 100, the minimum distance between one or more components of the heater assembly and the tubular body 4a of the article 110 may be in the range of 3 mm to 10 mm, for example 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0271] The device 100 of this example comprises a first end member 106, and the first end member 106 comprises a lid 108 that is movable relative to the first end member 106 to close the opening 104 when the article 110 is not in place. In Figure 8, the lid 108 is shown in the open configuration, but the lid 108 can be moved to the closed configuration. For example, the user can slide the lid 108 in the direction of arrow “B”.

[0272] Device 100 may also include a user-operable control element 112, such as a button or switch that, when pressed, operates the device 100. For example, the user can turn on the device 100 by operating the switch 112.

[0273] Device 100 may also include an electrical component, such as a socket / port 114 that can receive a cable to charge the battery of the device 100. For example, the socket 114 may be a charging port, such as a USB charging port.

[0274] FIG. 8 shows the device 100 of FIG. 7 with the outer cover 102 removed and the article 110 not present. The device 100 defines a longitudinal axis 134.

[0275] As shown in FIG. 8, the first end member 106 is disposed at one end of the device 100, and the second end member 116 is disposed at the opposite end of the device 100. Both the first end member 106 and the second end member 116 at least partially define the end face of the device 100. For example, the bottom surface of the second end member 116 at least partially defines the bottom surface of the device 100. The edge of the outer cover 102 may also define a portion of the end face. In this example, the lid 108 also defines a portion of the upper surface of the device 100.

[0276] The end of the device closest to the opening 104 is sometimes known as the proximal end (or mouth-side end) of the device 100 because it is closest to the user's mouth during use. During use, the user inserts the article 110 into the opening 104, operates the user control 112 to start heating the aerosol-generating material, and inhales the aerosol generated within the device. Thereby, the aerosol flows through the device 100 along the flow path towards the proximal end of the device 100.

[0277] The other end of the device that is farthest from the opening 104 is sometimes known as the distal end of the device 100 because it is the end that is farthest from the user's mouth during use. When the user inhales the aerosol generated within the device, the aerosol flows away from the distal end of the device 100.

[0278] The device 100 further comprises a power source 118. The power source 118 may be a battery, such as a rechargeable battery or a non-rechargeable battery, for example. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the heating assembly to supply power for heating the aerosol-generating material under the control of a controller (not shown) when required. In this example, the battery is connected to a central support 120 that holds the battery 118 in a fixed position.

[0279] The device further comprises at least one electronic module 122. The electronic module 122 may comprise, for example, a printed circuit board (PCB). The PCB 122 can support at least one controller, such as a processor, and memory. The PCB 122 may also comprise one or more electrical tracks for electrically connecting the various electronic components of the device 100 together. For example, the battery terminals may be 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 an electrical track.

[0280] In an exemplary device 100, the heating assembly is an induction heating assembly and includes various components for heating the aerosol-forming material of the article 110 by an induction heating process. Induction heating is a process of heating a conductor (such as a susceptor) by electromagnetic induction. The induction heating assembly can include an induction element, such as one or more inductor coils, and a device for passing a varying current, such as an alternating current, through the induction element. The varying current in the induction element creates a varying magnetic field. The varying magnetic field penetrates a susceptor suitably arranged relative to the induction element and generates eddy currents within the susceptor. The susceptor has an electrical resistance to the eddy currents, and thus the susceptor is heated by Joule heating as the eddy currents flow against this resistance. When the susceptor includes a ferromagnetic material such as iron, nickel, or cobalt, heat can also be generated by the magnetic hysteresis loss of the susceptor, i.e., by the orientation of the magnetic dipoles within the magnetic material varying as a result of aligning with the varying magnetic field. In induction heating, for example, compared to heating by conduction, heat is generated inside the susceptor, thereby enabling rapid heating. Further, no physical contact between the induction heater and the susceptor is required, thereby greatly increasing the degrees of freedom in terms of structure and use.

[0281] The inductive heating assembly of the exemplary device 100 includes a susceptor structure 132 (referred to herein as the "susceptor"), a first inductor coil 124, and a second inductor coil 126. The first inductor coil 124 and the second inductor coil 126 are made of a conductive material. In this example, the first inductor coil 124 and the second inductor coil 126 are made of a Litz wire / cable wound in a spiral to provide the spiral inductor coils 124, 126. The Litz wire includes a plurality of individual wires, which are individually insulated and twisted together to form a single wire. The Litz wire is designed to reduce the skin effect loss of the conductor. In the exemplary device 100, the first inductor coil 124 and the second inductor coil 126 are made of a copper Litz wire having a rectangular cross-section. In other examples, the Litz wire can also have a cross-section of other shapes, such as circular.

[0282] The first inductor coil 124 is configured to generate a first alternating magnetic field for heating a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second alternating 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 a direction along the longitudinal axis 134 of the device 100 (i.e., the first inductor coil 124 and the second inductor coil 126 do not overlap). The susceptor structure 132 may include a single susceptor or two or more separate susceptors. The ends 130 of the first inductor coil 124 and the second inductor coil 126 can be connected to the PCB 122.

[0283] In some examples, it will be appreciated that the first inductor coil 124 and the second inductor coil 126 may have at least one characteristic that is different from each other. For example, the first inductor coil 124 may have at least one characteristic that is different from the second inductor coil 126. More specifically, in one example, the first inductor coil 124 may have an inductance value that is different from the second inductor coil 126. In FIG. 8, the first inductor coil 124 and the second inductor coil 126 are of different lengths, and as a result, the first inductor coil 124 is wound around 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 than the second inductor coil 126 (assuming that the spacing between individual turns is substantially the same). In yet another example, the first inductor coil 124 may be made of a different material than the second inductor coil 126. In some examples, the first inductor coil 124 and the second inductor coil 126 may be substantially identical.

[0284] In this example, the first inductor coil 124 and the second inductor coil 126 are wound in opposite directions. This can be useful when the inductor coils are operating at different times. For example, initially, the first inductor coil 124 may operate to heat the first section / portion of the article 110, and then the second inductor coil 126 may operate to heat the second section / portion of the article 110. Winding the coils in opposite directions helps to reduce the current induced in the non-operating coil when used with a particular type of control circuit. In FIG. 8, 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 coil 124 and the inductor coil 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.

[0285] The susceptor 132 of this example is hollow and thus defines a receiving portion for receiving the aerosol - generating material. For example, the article 110 can be inserted into the susceptor 132. In this example, the susceptor 120 is tubular with a circular cross - section.

[0286] The susceptor 132 may be made of one or more materials. The susceptor 132 preferably includes carbon steel having a nickel or cobalt coating.

[0287] In some examples, the susceptor 132 may include at least two materials that can be heated at two different frequencies to selectively aerosolize at least two materials. For example, a first section of the susceptor 132 (heated by the first inductor coil 124) may include a first material, and a second section of the susceptor 132 heated by the second inductor coil 126 may include a different second material. In another example, the first section may include a first material and a second material, and based on the operation of the first inductor coil 124, the first material and the second material can be heated differently. The first material and the second material may be adjacent along the axis defined by the susceptor 132 or may form different layers within the susceptor 132. Similarly, the second section may include a third material and a fourth material, and based on the operation of the second inductor coil 126, the third material and the fourth material can be heated differently. The third material and the fourth material may be adjacent along the axis defined by the susceptor 132 or 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. Alternatively, each of the materials may be different. For example, the susceptor may include carbon steel or aluminum.

[0288] The device 100 of FIG. 8 further includes an insulating member 128, which can generally be tubular and at least partially surround the susceptor 132. The insulating member 128 may be composed of any insulating material such as, for example, plastic. In this particular example, the insulating member is composed of polyether ether ketone (PEEK). The insulating member 128 can help insulate various components of the device 100 from the heat generated by the susceptor 132.

[0289] The insulating member 128 can also fully or partially support the first inductor coil 124 and the second inductor coil 126. For example, as shown in FIG. 9, the first inductor coil 124 and the second inductor coil 126 are arranged 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 abut the first inductor coil 124 and the second inductor coil 126. For example, there may be a slight gap between the outer surface of the insulating member 128 and the inner surfaces of the first inductor coil 124 and the second inductor coil 126.

[0290] In a particular example, the susceptor 132, the insulating member 128, and the first inductor coil 124 and the second inductor coil 126 are concentric around the central longitudinal axis of the susceptor 132.

[0291] FIG. 10 is a side view of a partial cross-section of the device 100. In this example, there is an outer cover 102. The rectangular cross-sectional shapes of the first inductor coil 124 and the second inductor coil 126 can be seen more clearly.

[0292] The device 100 further includes a support portion 136 that engages with one end of the susceptor 132 to hold the susceptor 132 in a fixed position. The support portion 136 is connected to the second end member 116.

[0293] The device may also include a related second printed circuit board 138 within the control element 112.

[0294] Device 100 further includes a second lid / cap 140 and a spring 142 disposed toward the distal end of device 100. The spring 142 can open the second lid 140, allowing access to susceptor 132. A user can open the second lid 140 to clean the susceptor 132 and / or the support 136.

[0295] Device 100 further includes an expansion chamber 144 extending toward the opening 104 of the device away from the proximal end of susceptor 132. At least a retaining clip 146 is disposed within the expansion chamber 144 to abut and hold an article 110 when the article 110 is received within device 100. The expansion chamber 144 is connected to the end member 106.

[0296] FIG. 10 is an exploded view of device 100 of FIG. 9 with the outer cover 102 removed.

[0297] FIG. 11(A) shows a cross-section of a portion of device 100 of FIG. 9. FIG. 11(B) is an enlarged view of one region of FIG. 11(A). FIGS. 11(A) and (B) show an article 110 received within susceptor 132, where the article 110 is sized such that the outer surface of the article 110 abuts the inner surface of the susceptor 132. This ensures that heating is most efficient. The article 110 of this example includes an aerosol-generating material 110a. The aerosol-generating material 110a is disposed within the susceptor 132. The article 110 may also include other components such as a filter, packaging material, and / or a cooling structure.

[0298] FIG. 11(B) shows that the outer surface of the susceptor 132 is spaced apart by a distance 150, measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132, from the inner surfaces of the inductor coils 124, 126. In one particular example, the distance 150 is about 3 mm - 4 mm, about 3 - 3.5 mm, or about 3.25 mm.

[0299] (B) of FIG. 11 further shows that the outer surface of the insulating member 128 is spaced apart by a distance 152 when measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132 from the inner surfaces of the inductor coils 124, 126. In one particular example, the distance 152 is about 0.05 mm. In another example, the distance 152 is substantially 0 mm, and as a result, the inductor coils 124, 126 are in contact with and in contact with the insulating member 128.

[0300] In one example, the wall thickness 154 of the susceptor 132 is about 0.025 mm to 1 mm, or about 0.05 mm.

[0301] In one example, the length of the susceptor 132 is about 40 mm to 60 mm, about 40 mm to 45 mm, or about 44.5 mm.

[0302] In one example, the wall thickness 156 of the insulating member 128 is about 0.25 mm to 2 mm, 0.25 mm to 1 mm, or about 0.5 mm.

[0303] In use, the articles 1, 1', 1'', 1''' described herein can be inserted into a non-combustible aerosol supply device such as the device 100 described with reference to FIGS. 7 to 11(B). At least a portion of the suction ports 2, 2', 2'', 2''' of the articles 1, 1', 1'', 1''' protrude from the non-combustible aerosol supply device 100 and can be placed in the user's mouth. The aerosol is generated by heating the aerosol-forming material 3 using the device 100. The aerosol generated by the aerosol-forming material 3 reaches the user's mouth through the suction port 2.
