[Figure 7] An alternative method for forming articles according to this disclosure is outlined. [Modes for carrying out the invention]

[0024] In the figures described herein, similar reference numerals are used to indicate equivalent features, articles, or components.

[0025] Figure 1 is a side cross-sectional view of article 1 for use in an aerosol supply system. In this case, the article comprises consumables for a non-combustible aerosol supply system.

[0026] The article comprises an aerosol generating section, in this case a cylindrical aerosol generating material rod 2, and a mouthpiece 3 located downstream of the aerosol generating material rod 2 and connected to the aerosol generating material rod 2. In this case, the aerosol generating material is tobacco. In other examples, the aerosol generating material may be a non-tobacco plant material containing an active material or substance as defined herein. Article 1 may be used in a non-combustible aerosol supply device to form a non-combustible aerosol supply system. In other examples, Article 1 may include a heat source of Article 1 itself to form an aerosol supply system without requiring a separate aerosol supply device.

[0027] In some examples, the aerosol-generating material contains an amount of aerosol-forming agent of 10% to 30% by dry weight. The article further comprises a component 4 at the upstream end of the article. Component 4 includes a material body 5 covered within a component wrapper 6.

[0028] In this case, the component wrapper 6 is foil-backed paper. In other examples, the component wrapper 6 may be metal foil or paper plug wrap. The structure of component 4 will be described in more detail below with reference to Figures 3A and 3B.

[0029] As will be explained in more detail below, providing component 4 at the upstream end of article 1 offers several advantages. For example, during use, the stability of article 1 can be improved by preventing the aerosol-generating material from detaching from the upstream end of article 1. If component 4 includes a material body having a suction resistance of approximately 5% to 25% of the suction resistance of article 1, this also results in improved consistency of suction resistance between articles, as the contribution of the aerosol-generating material rod 2 to the overall suction resistance of article 1 is relatively small. Advantageously, the relatively high suction resistance of component 4 can reduce the influence of variations in the suction resistance of the aerosol-generating material rod 2 on the overall suction resistance of article 1.

[0030] Component 4 is connected to the aerosol-generating material rod 2 by a connecting wrapper 7. In this example, the connecting wrapper 7 is a paper wrapper. In other examples, the connecting wrapper 7 may be a paper-backed foil wrapper or a metal foil. Preferably, at least one of the covering material 6 and the connecting wrapper 7 includes a layer or coating of a non-combustible material, preferably a non-combustible material or a metal foil. In some examples, at least one of the covering material 6 and the connecting wrapper 7 is non-combustible. For example, the covering material 6 or the connecting wrapper 7 may be aluminum foil or paper-backed aluminum foil, or may include a layer or coating of paper and a non-combustible material. Advantageously, by providing an article in which the upstream component 4 of the article is surrounded by a non-combustible material such as metal foil, it is possible to prevent the user of the article from setting it on fire like a conventional cigarette, if the article is not intended for such use. In this example, the connecting wrapper 7 surrounds substantially the entire length of the component 4 and the aerosol-generating material rod 2.

[0031] Advantageously, additional strength and rigidity can be imparted to the aerosol-generating material rod 2 by connecting the component 4 to the aerosol-generating material rod 2 using a connecting wrapper 7 that extends substantially along the entire length of the aerosol-generating material rod 2. This may be particularly advantageous when the aerosol-generating material is not very dense, or when the aerosol-generating material is provided in a form where structural stability is inherently low, such as granular tobacco.

[0032] The connecting wrapper 7 is bonded to both the component 4 and the aerosol-generating material rod 2. At least a portion of the inner surface of the connecting wrapper 7 is covered with an adhesive layer. Surprisingly, it has been found that applying a small amount of adhesive to the connecting wrapper 7 can result in improved aerosol formation. This can be achieved by reducing the thickness of the adhesive layer, or preferably by creating gaps in the adhesive layer. Preferably, the adhesive layer is discontinuous. For example, the adhesive may be applied to the connecting wrapper 7 in a band before joining the component 4 and the tobacco rod 2, so that the rest of the connecting wrapper 7 contains no adhesive at all. When the connecting wrapper 7 with adhesive bands is wrapped around the component 4 and the aerosol-generating material rod 2, portions of the component 4 and portions of the aerosol-generating material rod 2 may be without adhesive. The adhesive bands may extend at various angles, such as in the same direction as the longitudinal axis of the article, perpendicular to the longitudinal axis of the article, or oblique to the longitudinal axis. By providing a discontinuous layer of adhesive on the inner surface of the connecting wrapper 7, the tensile strength of the connecting wrapper 7 can be increased during manufacturing. Since less of the connecting wrapper 7 is wetted by the adhesive, the ease of manufacturing the article 1 can be advantageously improved.

[0033] Other means may be used to vary or decrease the amount of adhesive applied to the connecting wrapper 7. For example, the adhesive layer may be applied in a different pattern, such as a dot matrix.

[0034] Preferably, at least a portion of the inner surface area of ​​the connecting wrapper 7 is free of adhesive. More preferably, at least 30%, at least 40%, or at least 50% of the inner surface area of ​​the connecting wrapper 7 is free of adhesive.

[0035] Ideally, the connecting wrapper 7 has a tensile strength of at least 2.5 kgf / 15 mm, for example, at least 3 kgf / 15 mm, or at least 3.5 kgf / 15 mm. The tensile strength of the connecting wrapper 7 can be determined according to test method T494.

[0036] In some examples, the connecting wrapper 7 has permeability of at least 3 cholesta units. In some examples, the connecting wrapper 7 has permeability of at least 5 cholesta units, at least 10 cholesta units, or at least 20 cholesta units. In some examples, this permeability is an inherent property of the connecting wrapper 7. In other examples, the connecting wrapper 7 may be provided with small pores to increase material permeability. In some examples, the combined permeability of the rod wrapper 10 and the connecting wrapper 7, together with any intermediate layer of adhesive, is at least 25 cholesta units, or at least 30 cholesta units, or at least 50 cholesta units. The combined permeability of the rod wrapper 10 and the connecting wrapper 7 with any intermediate layer of adhesive may be determined by disassembling article 1 to separate the covering material from the aerosol-generating material rod and measuring the total permeability through the covering material surrounding the aerosol-generating material rod, i.e., the rod wrapper 10, the connecting wrapper 7, and any intermediate layer of adhesive, in accordance with ISO 2965:2019.

[0037] In some examples, the connecting wrapper 7 has a basis weight of approximately 27 gsm to approximately 70 gsm, for example, approximately 36 gsm to approximately 50 gsm, or approximately 36 gsm, approximately 41 gsm, approximately 44 gsm, or approximately 48 gsm. Using basis weights within these ranges results in a configuration that improves the hardness and elasticity of the article, for example, during and after use of the article in the heating device described herein.

[0038] In this case, component 4 is adjacent to the upstream end of the aerosol-generating material rod 2. In other examples, two or more components may be provided upstream of the aerosol-generating material rod. For example, the first component 4 may be provided at the upstream end of the article, and the second component may be provided between the first component 4 and the aerosol-generating material rod 2.

[0039] In this example, article 1 has a circumference of approximately 21 mm (i.e., the article is demi-slim). Preferably, article 1 has an aerosol-generating material rod having a circumference greater than 19 mm. This has been found to provide a sufficient circumference to generate an improved, sustained aerosol throughout a typical aerosol-generating session, which is preferable for consumers. When the article is heated, heat is transferred through the aerosol-generating material rod 2, causing the components of the rod to volatilize, and a circumference greater than 19 mm has been found to be particularly effective in generating an aerosol in this manner. Since the article will be heated and release an aerosol, improved heating efficiency can be obtained by using an article with a circumference of less than approximately 23 mm. A rod circumference greater than 19 mm and less than 23 mm is preferred to obtain an improved aerosol by heating while maintaining a suitable product length. In some examples, the rod circumference may be 20 mm to 22 mm, which has been found to provide a good balance between effectively delivering the aerosol and enabling efficient heating.

[0040] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the aerosol-generating material rod 3, so that there is a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm.

[0041] In this example, the intake includes a cooling section 13 located downstream of the aerosol-generating material rod 2. In this example, the cooling section 13 is in contact with the aerosol-generating material rod 2. In other examples, additional components may be provided between the aerosol-generating material rod 2 and the cooling section 13.

[0042] In this example, the mouthpiece 3 also includes a mouthpiece body 14 downstream of the cooling section 13, and includes a hollow tubular element 15 downstream of the mouthpiece body 14 and at the mouth-side end of the article 1. In other examples, the hollow tubular element 15 may be omitted, and the mouthpiece body 14 may form the mouth-side end of the article. In some examples where the hollow tubular element 15 is omitted, the length of the mouthpiece body 14 may be increased, or an additional material body may be provided at the mouth-side end.

[0043] In this example, the cooling section 13 defines a void within the mouthpiece. The void provides a chamber through which the heat-volatile components generated by the aerosol-generating material rod 2 flow. The cooling section 13 is hollow to provide a chamber for storing the aerosol, but is rigid enough to withstand the axial compressive forces and bending moments that can occur during manufacture and while the article 1 is in use. The cooling section 13 causes a physical displacement between the aerosol-generating material rod 2 and the downstream portion of the mouthpiece 3.

[0044] Preferably, the internal volume of the cooling section 13 is greater than 130 mm 3 It has been found that providing a cavity of at least this volume enables improved aerosol formation. The size of such a cavity provides sufficient space within the mouthpiece 2 to allow the heat-volatile components to cool, thus exposing the aerosol-generating material 2 to a lower temperature than would otherwise occur, because they can cause the aerosol to become overly hot. More preferably, the mouthpiece 3 has a cavity with an internal volume greater than 170 mm 3 and even more preferably greater than 200 mm 3 to enable further improvement of the aerosol. In some examples, the internal cavity has a volume of from about 130 mm 3 to about 700 mm 3 and preferably from about 160 mm 3 to about 700 mm 3 For example, the internal cavity may have a volume of from about 170 mm 3 to about 300 mm 3 ​

[0045] The cavity may be configured to create a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. Preferably, the cavity may be configured to create a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius, between the heated volatile components entering the first upstream end of the cavity and the heated volatile components exiting the second downstream end of the cavity. This temperature difference along the length of the cavity can protect temperature-sensitive elements at the downstream intake of the cavity from the high temperature of the aerosol-generating material 2 when heated.

[0046] Preferably, the length of the cooling section 13 is less than about 50 mm. More preferably, the length of the cooling section 13 is less than about 40 mm. Even more preferably, the length of the cooling section 13 is less than about 35 mm. Additionally or alternatively, the length of the cooling section 13 is preferably at least about 10 mm. Preferably, the length of the cooling section 13 is at least about 15 mm.

[0047] In some preferred embodiments, the length of the cooling section 13 is about 15 mm to about 35 mm, more preferably about 20 mm to about 30 mm, even more preferably about 23 mm to about 27 mm, and most preferably about 25 mm. In this example, the length of the cooling section 13 is 25 mm.

[0048] In this example, the cooling section 13 is formed from multiple layers of paper wound parallel to each other with their seams joined together to form a hollow tube. In this example, the first and second layers of paper are provided in a double tube, but in other examples, three, four, or five or more layers of paper can be used to form triple, quadruple, or quintuple or more tubes. Other configurations can be used, such as spirally wound layers of paper, cardboard tubes, tubes formed using a papier-mache process, molded plastic tubes, or extruded plastic tubes.

[0049] In some embodiments, the cooling section 13 preferably has a wall thickness of at least about 50 μm to a maximum of about 1 mm, preferably 100 μm to 500 μm, and more preferably 100 μm to 150 μm. In this example, the cooling section 13 has a wall thickness of about 150 μm. The “wall thickness” of the cooling section corresponds to the wall thickness of the hollow tube in the radial direction and does not include the surrounding material in which the hollow tube may be embedded. The wall thickness of the cooling section 13 can be measured, for example, using a caliper.

[0050] In some embodiments, the wall thickness of the cooling section 13 is at least 50 microns, preferably at least 75, 80, 85, 90, 95, 100, or 105 microns. In some embodiments, the wall thickness of the cooling section is at least 100 or 110 microns.

[0051] In some embodiments, the wall thickness of the cooling section 13 is less than 1000 microns, preferably less than 500 microns.

[0052] The cooling section 13, the suction port body 14, and the hollow tubular element 15 are connected by a bonding covering material 11.

[0053] In this example, article 1 is provided with first and second parallel rows of small holes 12 through the tip material 9, connecting the coating material 11 and the cooling section 13, and providing ventilation into the intake port 3 in the cooling section 13. In this example, the small holes 12 are formed as laser-cut holes at positions approximately 18 mm and 19 mm, respectively, from the downstream mouth end 3b of the intake port 3. In other examples, ventilation into the intake port 3 may be provided at other positions.

[0054] In this embodiment, the mouthpiece body 14 is a filter. However, it should be recognized that in other examples, the mouthpiece body 14 may provide the aerosol generated by article 1 without substantially filtering it.

[0055] The mouthpiece body 14 is formed from a fibrous material. In this example, the mouthpiece body 14 is formed from a sheet material. In this example, the sheet material is paper. The sheet material may be folded to form the mouthpiece body 14. The mouthpiece body 14 may be formed from a continuous web of the sheet material. In this example, the sheet material is gathered in a manner similar to that of a "crepe filter" to form the body 14.

[0056] The hollow tubular element 15 is positioned at the mouth end of article 1. In this example, the hollow tubular element 15 is formed from multiple layers of paper wound parallel to each other with their seams butted together to form a hollow tube, as described with respect to the cooling section 13. The hollow tubular element 15 may be formed according to any of the means described with respect to the cooling section 13 and may have any wall thickness described with respect to the cooling section 13.

[0057] Preferably, the length of the hollow tubular element 15 is less than about 20 mm. More preferably, the length of the hollow tubular element 15 is less than about 15 mm. Even more preferably, the length of the hollow tubular element 15 is less than about 10 mm. Additionally or alternatively, the length of the hollow tubular element 15 is at least about 5 mm. Preferably, the length of the hollow tubular element 15 is at least about 6 mm. In some preferred embodiments, the length of the hollow tubular element 15 is about 5 mm to about 20 mm, more preferably about 6 mm to about 10 mm, even more preferably about 6 mm to about 8 mm, most preferably about 6 mm, 7 mm, or about 8 mm. In this example, the length of the hollow tubular element 15 is 6 mm.

[0058] In this example, the tip paper 9 is wrapped around the entire length of the mouthpiece 3 and around a portion of the aerosol-generating material rod 2, and has an adhesive on its inner surface to connect the mouthpiece 3 and the rod 2. In this example, the tip paper 9 extends 5 mm over the aerosol-generating material rod 2, but alternatively, it can extend 3 mm to 15 mm, or more preferably 4 mm to 6 mm, over the rod 2 to provide a secure attachment between the mouthpiece 3 and the rod 2.

[0059] In this example, the aerosol-generating material rod 2 is covered within a rod wrapper 10. The rod wrapper 10 can be, for example, paper or a paper-backed foil wrapper. As described above, the connecting wrapper 7 surrounds the approximately entire length of the aerosol-generating material rod 7 such that the aerosol-generating material rod is surrounded by two wrappers along its approximately entire length. Such a double-wound rod of aerosol-generating material can have increased stiffness and / or rigidity. Advantageously, this makes it possible to provide a lower-density aerosol-generating material rod while maintaining a desired level of rigidity.

[0060] In some examples, the rod wrapper 10 may contain flavorings, aerosol modifying additives, aerosol forming agents, or aerosol generating materials.

[0061] Figure 2 is a side cross-sectional view of a further article 1' for use in an aerosol supply system. Article 1' is substantially the same as article 1, except for the configuration of the component 4 and the wrapper surrounding the aerosol-generating material rod 2. In article 1', the connecting wrapper 7 is replaced by a connecting wrapper 7' that surrounds the component 4 and a portion of the aerosol-generating material rod 2. The connecting wrapper 7' extends over only a portion of the aerosol-generating material rod 2. For example, the connecting wrapper 7' may extend over the aerosol-generating material rod by about 3 mm to about 10 mm, for example, about 5 mm.

[0062] The connecting wrapper 7' may be the same as the connecting wrapper 7, except for its length. The connecting wrapper 7' has a length such that it does not extend over the entire length of the aerosol generating material rod 2.

[0063] Figure 3A is a cross-sectional view of component 4 in Figures 1 and 2, passing through line X-X' in Figure 1. Component 4 includes a material body 5 and a covering material 6, and is shown separately from the rest of Article 1. As shown, the material body 5 is formed from a corrugated and gathered material sheet 8. The sheet 8 is gathered laterally to form a body 5 having a substantially cylindrical outer shape.

[0064] In some cases, the sheet 8 has a permeability of approximately 1,000 to 50,000 cholesta units, and in other cases, approximately 5,000 to 50,000 cholesta units. Such levels of permeability are advantageous because they result in a more uniform distribution of the material forming the body 5, resulting in fewer chances of forming channels extending longitudinally through the body 5. Therefore, for a given weight of sheet material 8, increasing permeability leads to higher suction resistance throughout the entire length of the body 5. This means that a sheet material 8 with a lower average density can be used in the body 5 to obtain the desired suction resistance and thus to conserve material.

[0065] Furthermore, a sheet material 8 with higher permeability also has a more open structure, and therefore, in the case of a biodegradable material, this can result in an improvement in the time it takes for the components 4 to decompose. When the additive is applied to the sheet material 8 in liquid form, the increase in permeability can also result in a more absorbent sheet material 8, meaning that a larger amount of additive can be applied to a given weight of material.

[0066] The permeability of material sheet 7 can be measured according to the international standard ISO 2965:2019, as is known to those skilled in the art.

[0067] Biodegradability can be measured according to the procedure described in ISO 14855-2:2018. Components such as those described herein can achieve more than 50% biodegradation in 30 days when exposed to either freshwater or seawater.

[0068] In other examples, the sheet material may be non-porous, having a porosity of, for example, less than 100 cholesta units, or less than 50 cholesta units. In some examples, the sheet material 8 may include metal foil. For example, the sheet material 8 may be metal foil or paper-backed metal foil.

[0069] In this example, the main body 5 has a suction resistance of 1 mmH2O to 30 mmH2O, for example, 5 mmH2O to 25 mmH2O, or 10 mmH2O to 20 mmH2O. Preferably, the main body 5 has a suction resistance of 0 mmH2O to 20 mmH2O. In some examples, the suction resistance along the length of the main body 5 is 4 mmH2O to 20 mmH2O. This suction resistance may be 1% to 30%, for example, 5% to 25%, or 10% to 20%, of the suction resistance along the entire length of the article. Advantageously, by providing a component 4 having a suction resistance of 5% to 25% of the suction resistance along the entire length of the article at a position upstream of the aerosol-generating material rod 2, the relative contribution of the aerosol-generating material rod to the overall suction resistance of the article is reduced. As a result, the overall suction resistance of article 1 is less affected by variations in the suction resistance of the aerosol-generating material rod that may occur due to the organic properties of the tobacco material, and it is possible to bring a higher level of ventilation into the aerosol-generating material rod while maintaining the overall suction resistance throughout the entire length of article 1 at an acceptable level. Ventilation may be brought into the aerosol-generating material rod 2 such that the overall level of ventilation in article 1 is 10% to 60%, or 25% to 80%, for example, up to 70%, up to 65%, up to 60%, up to 55%, or up to 50%.

[0070] The suction resistance of unit 5 is measured according to the ISO standard method (ISO 6565:2015). Suction resistance refers to "closed suction resistance," in which case any ventilation area to the article or unit being measured is closed.

[0071] In some examples, the suction resistance of the main body 5 is at least 5 mmH2O, or at least 7 mmH2O, or at least 8 mmH2O.

[0072] In some examples, the suction resistance of body 5 is at least 1.1 mmH2O per 1 mm of body length, or at least 1.5 mmH2O per 1 mm of body length, or at least 2 mmH2O per 1 mm of body length.

[0073] Article 1 in this example has a permeability level of approximately 70% of the aerosols that are drawn in through Article 1.

[0074] In this example, the body 5 is formed from a single gathered sheet of material 8. However, in an alternative example, the body 5 may be formed from multiple sheets of material 8 that are gathered together to form the body 5. Each of the multiple sheets of material may have the same or different properties, such as their dimensions, permeability, thickness, basis weight, and composition.

[0075] One or more sheets 8 forming the material body 5 can have a total width of 100 mm to 240 mm, for example, 140 mm to 200 mm, before any corrugation processing. Such a width can provide a good balance between the pressure drop throughout the entire length of the material body 5 and the hardness of the material body 5.

[0076] One or more sheets 8 forming the main body 5 may be made of cellulose material. For example, one or more sheets may be paper sheets, tobacco material sheets, non-tobacco plant material sheets, or a combination thereof. One or more sheets 8 forming the main body 5 may have a basis weight of about 20 to about 80 gsm, or about 30 to about 50 gsm, or about 36 to about 45 gsm, or about 55 to about 75 gsm. Alternatively or additionally, one or more sheets may have an uncorrugated thickness of about 50 μm to about 500 μm, about 50 μm to about 350 μm, about 60 μm to about 300 μm, or about 60 μm to about 160 μm.

[0077] In some examples, the sheet material 8 may include a metal foil, such as aluminum foil, or optionally paper-backed aluminum foil. In other examples, the sheet material may include an aerosol-generating material, such as recycled paper tobacco material, or an aerosol-generating film. Optionally, the aerosol-generating film may be laminated on a support material such as paper.

[0078] The material body 5 may have a weight of approximately 5 mg to approximately 15 mg per 1 mm of length of the body, or approximately 8 mg to approximately 12 mg per 1 mm of length of the body, or approximately 10 mg per 1 mm of length of the body.

[0079] The amount of sheet material that can be included in the body 5 can be increased by processing one or more sheets 8 into a corrugated shape. At least one of the one or more sheets 8 extending through the body 5 may include corrugated sheet material formed to have a corrugated pattern including a series of substantially parallel ridges and grooves.

[0080] In this example, the sheet material 8 is corrugated before being formed into the body 5. For example, the sheet material 8 may be passed through a pair of corrugating rollers. In this example, the first body 5 comprises the corrugated sheet material 8 formed with a corrugated pattern having a series of substantially parallel ridges and grooves. Corrugation can make it easier to gather the sheet material 8 to form the body 5. Corrugation can also increase the width of the sheet material 8 which can be used to form a body 5 of a particular volume. Increasing the width of the sheet material 8 within the body 5 increases the available surface area of ​​the sheet material within the body 5, which can increase the amount of moisture that can be absorbed by the body 5. Thus, more condensates can be absorbed by the body 5, resulting in a more hygienic user experience when the article 1 is used in a non-combustible aerosol supply device.

[0081] In this example, the average spacing between adjacent raised areas of sheet material 8 is greater than approximately 0.3 mm. Also, in this example, the amplitude of the waveform is less than approximately 0.7 mm.

[0082] The amplitude of the waveform (also known as the "crimp coefficient") refers to the depth of the grooves formed by corrugating the sheet material 8 that forms the main body. That is, as shown in Figure 3B, by corrugating the sheet material 8, a number of peaks and valleys are created in the sheet material 8 when viewed from a first side of the sheet material 8, and the amplitude of the waveform "A" is the depth of the valleys measured from those peaks. The corrugation can form a "zigzag" shape or another shape. In some examples, adjacent grooves in the corrugated sheet material 8 are spaced apart at a distance in the range of 0.3 to 2 mm, preferably in the range of 0.4 to 1 mm, or have a pitch "P". In some embodiments, adjacent grooves in the corrugated sheet material are spaced apart at a distance in the range of 0.1 to 3 mm, preferably in the range of 0.2 to 2 mm. In some embodiments, adjacent grooves in the corrugated sheet material 10 are spaced at a distance of at least 0.1 mm, preferably at least 0.2, 0.5, 0.7, 1, 1.5, 2, 2.5, or 3 mm. In some embodiments, adjacent grooves in the corrugated sheet material are spaced at a distance of at most 3 mm, preferably at a distance of at most 2.5, 2, 1, 1.5, 0.7, 0.5, 0.2, or 0.1 mm.

[0083] For example, the sheet material 8 may have a waveform having a waveform amplitude of less than 500 μm and a spacing between peaks (or troughs) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0084] In some embodiments, the sheet material 8 is heated when it is processed into a corrugated shape. For example, the sheet material 8 may be passed between corrugating rollers, where one or both of the corrugating rollers are heated. For example, one or both of the rollers may be heated to a temperature of up to 100 degrees Celsius, for example, 50 degrees Celsius or 60 degrees Celsius. The amount of pressure applied to the sheet material as it passes between the rollers may also be varied. A higher level of corrugation can be achieved by heating the roller(s) or by applying a higher level of pressure to the sheet material. For example, the corrugation can be achieved using roller surfaces with temperatures above 30°C, above 40°C, or above 50°C.

[0085] The average density of the main body 5 is approximately 0.1 to 0.25 mg / mm³. 3 This can be achieved. In this example, the density of the main material 5 is approximately 0.19 mg / mm³. 3 In some embodiments, the body 5 contains at least 0.1 mg / mm³ 3 , 0.12 mg / mm³ 3 or 0.15 mg / mm³ 3 It has a density of . The density of the material body can be measured by separating the body from the article and the surrounding plug wrap and / or chip paper and removing any embedded material, including any additives added to the sheet material 8. The density may be calculated as a tightness based on the weight of the sheet material 8 and any additives added to the sheet material 8, as well as the total volume occupied by the sheet material 8. For example, the total volume of the material body 5 measured inside the plug wrap 6.

[0086] In some examples, the material itself is formed not from a sheet material, but from another fibrous material such as cotton.

[0087] In some examples, an aerosol modifier or aerosol-forming agent may be added to the material forming the material body. For example, a fragrance carrier or glycerol may be applied to the sheet material 8 before forming the material body 5. In some examples, the material body 5 includes an aerosol-generating film containing lactic acid, as described, for example, in International Publication No. 2021 / 105449. In some examples, the material body contains an acid, selected from the group consisting of, for example, lactic acid, levulinic acid, benzoic acid, citric acid, 2-methylbutyric acid, or 2-methylvaleric acid. In some embodiments, the acid is lactic acid. In some embodiments, the acid is levulinic acid. The term lactic acid is synonymous with the term 2-hydroxypropanoic acid and includes both the D-enantiomer and L-enantiomer separately, or mixtures thereof. For example, lactic acid may be a mixture of D-2-hydroxypropanoic acid and L-2-hydroxypropanoic acid (e.g., a racemic mixture). The term levulinic acid is synonymous with the term 4-oxopentanoic acid.

[0088] The use of an acid within the material body 5 may be particularly advantageous when the aerosol-generating material contains nicotine, because the acid can enable optimal protonation of nicotine in the resulting aerosol, for example, by changing the ratio of free base nicotine to protonated nicotine. It is understood that the protonation of nicotine in the aerosol-generating material changes the nicotine (gas):nicotine (fine particles / liquid) ratio by increasing the amount of nicotine present in the fine particles / liquid phase. The aerosol produced by the aerosol-generating material described herein delivers an appropriate amount of nicotine to the user.

[0089] In some cases, the main body 5 contains an amount of aerosol-forming agent equivalent to 10% to 30% by dry weight.

[0090] In other examples, the material body 5 contains an amount of aerosol-forming agent less than 5% by weight on a dry weight basis.

[0091] In other examples, the material body 5 includes a combustion retarding material, such as a combustion retarding salt and aerosol-generating film, or a salt gel, as described in International Publication No. 2020 / 183163. In some embodiments, the combustion retarding salt is incorporated into an amorphous solid material to form a salt gel as referred to herein. This means that the combustion retarding salt is contained within the amorphous solid composition. For example, during the preparation of the amorphous solid material, the liquid precursor of the amorphous solid material is mixed with the combustion retarding salt. This distributes the combustion retarding salt throughout the resulting amorphous solid material. In some embodiments, the distribution of the combustion retarding salt is uniform throughout the amorphous solid, which can be advantageous because the combustion retarding effect is effective throughout the entire material. The combustion retarding salt may be added in the form of a solution or suspension. Alternatively, the combustion retarding salt may be added to the liquid precursor in solid form, such as particulate form, such as a powder.

[0092] In other embodiments, the combustion retarder salt is added to or applied to an amorphous solid material. For example, once the amorphous solid material is prepared, a solution or suspension containing the combustion retarder salt is applied to the surface of the amorphous solid material to deposit the combustion retarder salt on the surface of the amorphous solid material.

[0093] In this example, component 4 has a length of approximately 6 mm. In alternative embodiments, component 4 may have any length in the range of approximately 3 mm to approximately 15 mm, preferably approximately 4 mm to approximately 6 mm.

[0094] The outer circumference of component 4 is substantially the same as the outer circumference of the aerosol-generating material rod 2, so as to be the case that there is a smooth transition between these components.

[0095] Although only a single material body 5 has been described with reference to the drawings, in alternative embodiments, Article 1 in Figures 1 and 2A / 2B may include additional sections, such as additional material bodies, or other sections, such as tubular sections. The additional sections may be immediately upstream, immediately downstream, or both of the component 4, and may be formed from any material suitable for use in the articles described herein.

[0096] In some examples, the component wrapper 6 has a basis weight of approximately 27 gsm to approximately 70 gsm, for example, approximately 36 gsm, approximately 41 gsm, or approximately 44 gsm.

[0097] Figure 4 is a side cross-sectional view of an additional article 1'' for use in a non-combustible aerosol supply system. Article 1'' is substantially the same as article 1, except for the arrangement of wrappers connecting the components of the article. In this example, the mouthpiece 3 comprises a cooling section 13, a mouthpiece body 14, and a hollow tubular element 15 connected by a covering material 11, and is joined to the aerosol-generating material rod 2 and component 4 by an additional wrapper 17 extending substantially along the entire length of article 1''. In this example, the additional wrapper 17 includes paper such as chip paper.

[0098] Figure 5 is a side cross-sectional view of a further article 1''' having an additional component 41 at the upstream end of the article. Article 1''' is substantially the same as article 1, except that in this example the length of component 4 is shortened and the additional component 41 is located upstream of component 4. The additional component 41 may be formed in the same manner as component 4 in Figure 1. In this example, each of components 4, 41 has a length of 3 mm such that the combined length of components 4, 41 is the same as that of component 4 in Figure 1. In other examples, components 4, 41 may have any suitable length as described above with respect to component 4.

[0099] In this example, the material body 5 of the downstream component 4 may preferably contain an aerosol-forming agent or an aerosol-modifying additive. By adding an aerosol-forming agent or an aerosol-modifying additive to the body 4, an improved aerosol can be generated.

[0100] By providing adjacent components 4 and 41 at the upstream end of article 1''', the aerosol-generating material rod 2 can be advantageously displaced from the distal end of the heating device into which article 1''' is inserted during use toward a region where the aerosol-generating material can be heated more effectively. Such an effect can be further enhanced by providing component 41 configured to function as a heat exchanger at the upstream end of article 1''', which can advantageously improve heat transfer to the air flowing into article 1'''. This may be achieved, for example, by providing component 41 including a body 51 formed from a strip of metal foil, such as aluminum foil.

[0101] In an example where the upstream component 41 includes a strip of metal foil and the downstream component 4 includes an aerosol-forming agent or aerosol-modifying additive, the aerosol generated by the article during use can be particularly improved. The combined effect of the upstream component 41 improving the heating of the air flowing into the article 1'' and the downstream component 4 providing an additional aerosol-forming agent or aerosol-modifying additive can, advantageously, improve the consumer experience of the article 1'' during use.

[0102] In this example, the additional component 41 includes a material body 51. The material body 51 may be formed in any suitable manner from any material as described with respect to the material body 5. In this example, the material body 51 includes strands or strips of material gathered to form the body 51. In this example, the strands or strips are aluminum foil.

[0103] Components 4 and 41 are each surrounded by component wrappers 6 and 61, as described above in relation to Figure 1, and joined by a connecting wrapper 7. In an alternative example, components 4 and 41 may be joined by further coating material before being joined to the aerosol-generating material rod by the wrapper 7.

[0104] In some examples, Article 1 according to the present disclosure may be formed by the method shown in Figure 6. This method includes the steps of: preparing a material body, an aerosol generating portion and a coating material (S101); forming a component by joining the material body and the aerosol generating portion with the coating material (S102); further preparing a mouthpiece and further coating material (S103); and forming an article by joining the mouthpiece and the component (S104).

[0105] In an alternative example, article 1'' according to the present disclosure may be formed by the method shown in Figure 7, which includes the steps of: preparing a cooling section, a mouthpiece body, a hollow tubular element and a coating material (S101); forming a mouthpiece by joining the cooling section, the mouthpiece body and the hollow tubular element with a coating material (S102); further preparing an aerosol generating section, a material body and a further coating material (S103); and forming an article by joining the mouthpiece, the aerosol generating section and the material body with a further coating material (S104).

[0106] The flammability of paper covering materials for use in articles may be determined in accordance with ISO 5729:2021.

[0107] For example, items in the shape of a rod are often named according to their length, such as "regular" (typically in the range of 68-75 mm, e.g., about 68 mm to about 72 mm), "short" or "mini" (68 mm or less), "king size" (typically in the range of 75-91 mm, e.g., about 79 mm to about 88 mm), "long" or "super king" (typically in the range of 91-105 mm, e.g., about 94 mm to about 101 mm), and "ultra long" (typically in the range of about 110 mm to about 121 mm).

[0108] The products are also named according to their circumference as follows: "Regular" (approximately 23-25mm), "Wide" (over 25mm), "Slim" (approximately 22-23mm), "Demi-Slim" (approximately 19-22mm), "Super Slim" (approximately 16-19mm), and "Micro Slim" (less than approximately 16mm).

[0109] Therefore, a king-size super-slim article has, for example, a length of approximately 83 mm and a circumference of approximately 17 mm.

[0110] Each form may be manufactured using mouthpieces of different lengths. The mouthpiece length is approximately 10mm to 50mm, for example, 15mm to 35mm. The tip paper connects the mouthpiece to the aerosol-generating material and is usually longer than the mouthpiece, for example, 3 to 15mm longer or 3 to 12mm longer. The tip paper covers the mouthpiece and overlaps the aerosol-generating material, for example, in the form of a rod of the aerosol-generating material, connecting the mouthpiece to the rod.

[0111] The articles described herein and their aerosol-generating materials and components may be manufactured in any of the above forms, but are not limited to these.

[0112] As used herein, the terms “upstream” and “downstream” are relative terms defined with respect to the direction of the mainstream aerosol drawn through the article or device during use.
