Description

Technical Field

[0001] The present invention relates to components and articles for use in an aerosol supply system, and to an aerosol supply system.

Background Art

[0002] Certain tobacco industry products generate an aerosol during use, which is inhaled by the user.

[Modes for carrying out the invention]

[0030] In the figures described herein, similar reference numerals are used to indicate equivalent features, articles, or components.

[0031] Figure 1 is a side cross-sectional view of article 1 for use in an aerosol supply system. In this case, the article includes consumables for a non-combustible aerosol supply system.

[0032] Article 1 comprises an aerosol generating section, in this case a cylindrical rod 2 of aerosol generating material, and a mouthpiece 3 located downstream of the rod 2 of aerosol generating material and connected to the rod 2 of aerosol generating material. In this case, the aerosol generating material 2 is tobacco. In other examples, the aerosol generating material 2 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 have its own heat source to form an aerosol supply system without requiring a separate aerosol supply device.

[0033] In some examples, the aerosol-generating material 2 contains an amount of aerosol-forming agent ranging from 10% to 30% by weight.

[0034] Article 1 further comprises an upstream component 4 at its upstream end. The upstream component 4 includes a material body 5 wrapped in a first packaging material 6.

[0035] In this case, the first packaging material 6 is foil-backed paper. In other examples, the first packaging material 6 may be metal foil or paper plug wrap. The structure of the upstream component 4 will be described in more detail below with reference to Figure 3A.

[0036] As will be described in more detail below, providing an upstream component 4 at the upstream end of article 1 can offer several advantages. In some examples, the upstream component 4 comprises a body 5 with very low suction resistance along its length. In such examples, component 4 may be provided at the upstream end of article 1 without significantly increasing the suction resistance along the entire length of article 1. Preferably, this makes it possible to provide an article having a standard length, but with the aerosol-generating portion located away from the upstream end of the article. For example, the aerosol-generating portion may be displaced so that it is positioned in the area of ​​a heating device where the aerosol-generating material has been found to be heated more effectively during use. In other examples, providing a low-suction-resistance component 4 at the upstream end of article 1 preferably makes it possible to achieve a relatively high density or relatively high suction resistance in the aerosol-generating portion while maintaining the desired weight, density or suction resistance of the entire article 1.

[0037] In some examples, the upstream component 4 has a length of 5% to 13% of the length of article 1. In some examples, the upstream component 4 does not contain aerosol-generating material.

[0038] In some examples, the stability of article 1 in use may be improved by providing an upstream component 4 at the upstream end of the article, thereby preventing the aerosol-generating material from falling out from the upstream end of the article.

[0039] The upstream component 4 is connected to the rod 2 of the aerosol-generating material by a connecting packaging material 7. In this case, the connecting packaging material 7 is wrapping paper. In other examples, the connecting packaging material 7 may be a paper-backed foil packaging material or a metal foil. Preferably, at least one of the first packaging material 6 and the connecting packaging material 7 includes a non-combustible material, preferably a non-combustible layer or coating such as a metal foil. In some examples, at least one of the first packaging material 6 and the connecting packaging material 7 is non-combustible. For example, the first packaging material 6 or the connecting packaging material 7 may be aluminum foil or paper-backed aluminum foil. Preferably, by providing an article in which the upstream component 4 is surrounded by a non-combustible material such as a metal foil, it is possible to prevent the user of the article 1 from igniting the article 1 like a conventional cigarette (the article is not intended for such use). In this example, the connecting packaging material 7 surrounds the upstream component 4 and the rod 2 of the aerosol-generating material substantially over its entire length.

[0040] Preferably, additional strength and rigidity can be achieved in the aerosol-generating material rod 2 by connecting the upstream component 4 to the aerosol-generating material rod 2 using a connecting packaging material 7 that extends substantially along the entire length of the aerosol-generating material rod 2. This may be particularly suitable when the aerosol-generating material is not very dense, or when it is provided in a form with an inherently low level of structural stability, such as granular tobacco.

[0041] The connecting packaging material 7 is bonded to both the component 4 and the rod 2 of the aerosol-generating material. At least a portion of the inner surface of the connecting packaging material 7 is covered with an adhesive layer. Surprisingly, it has been found that applying a small amount of adhesive to the connecting packaging material 7 can result in the formation of an improved aerosol. This may 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, before combining the component 4 and the tobacco rod 2, the adhesive may be applied in strips to the connecting packaging material 7 so that the rest of the connecting packaging material 7 is not completely coated with adhesive. If the connecting packaging material 7 with the strips of adhesive is wrapped around the component 4 and the rod 2 of the aerosol-generating material, then the portion of the component 4 and the rod 2 of the aerosol-generating material may not contain adhesive. The strips of adhesive may extend in the same direction as the longitudinal axis of the article, perpendicular to the longitudinal axis of the article, or at other angles such as oblique to the longitudinal axis. Providing a discontinuous layer of adhesive on the inner surface of the connecting packaging material 7 reduces the amount of the connecting packaging material 7 that gets wet with the adhesive, which can result in higher tensile strength of the connecting packaging material 7 during manufacturing, and thus preferably improves the ease of manufacturing of the article 1.

[0042] Other means can be used to change or reduce the amount of adhesive applied to the connecting packaging material 7. For example, the adhesive layer may be applied in a different pattern, such as a dot matrix.

[0043] Preferably, at least a portion of the inner surface area of ​​the connecting packaging material 7 is adhesive-free. More preferably, at least 30%, at least 40%, or at least 50% of the inner surface area of ​​the connecting packaging material 7 is adhesive-free.

[0044] Ideally, the connecting packaging material 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 packaging material 7 may be determined according to test method T494.

[0045] In some examples, the connecting packaging material 7 has a permeability of at least 3 cholesta units. In some examples, the connecting packaging material 7 has a 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 packaging material 7. In other examples, the connecting packaging material 7 may be perforated to increase material permeability. In some examples, the combined permeability of the rod packaging material 10 and the connecting packaging material 7, combined 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 packaging material 10 and the connecting packaging material 7, combined with any intermediate layer of adhesive, may be determined by disassembling the article 1 to separate the packaging material from the rod of aerosol-generating material and measuring the total permeability through the packaging material surrounding the rod of aerosol-generating material, i.e., the rod packaging material 10, the connecting packaging material 7, and any intermediate layer of adhesive, in accordance with ISO 2965:2019.

[0046] In some examples, the connecting packaging material 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. By using basis weights within these ranges, a configuration is achieved in which the hardness and elasticity of the article are improved, for example, during and after use of the article in the heating device described herein.

[0047] In this case, the upstream component 4 is adjacent to the upstream end of the rod 2 of the aerosol-generating material. In other examples, two or more components may be provided upstream of the rod of the aerosol-generating material. For example, the first upstream component 4 may be provided at the upstream end of the article, and the second component may be provided between the first upstream component 4 and the rod 2 of the aerosol-generating material.

[0048] In this example, article 1 has a circumference of approximately 21 mm (i.e., the article is demi-slim). Preferably, article 1 has a rod of aerosol-generating material with a circumference greater than 19 mm. This has been found to provide a circumference sufficient to generate an improved, sustained aerosol over a typical aerosol-generating session that is favorable to consumers. When the article is heated, heat is transferred through the rod 2 of the aerosol-generating material, causing the components of the aerosol-generating material to volatilize, and a circumference greater than 19 mm has been found to be particularly effective in generating aerosols in this manner. Since the article will be heated and release an aerosol, improved heating efficiency can be achieved 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 achieve improved aerosols by heating while maintaining a suitable product length. In some examples, the rod circumference can be 20 mm to 22 mm, which has been found to provide a good balance between achieving effective aerosol delivery and enabling efficient heating on the one hand.

[0049] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod 3 of the aerosol-generating material, so as to ensure a smooth transition between these components. In this example, the outer circumference of the mouthpiece 2 is approximately 20.8 mm.

[0050] In this example, the intake includes a cooling section 13 located downstream of the rod 2 of the aerosol-generating material. In this example, the cooling section 13 is in contact with the rod 2 of the aerosol-generating material. In other examples, additional components may be provided between the rod 2 of the aerosol-generating material and the cooling section 13.

[0051] In this example, the mouthpiece 3 also comprises a mouthpiece body 14 downstream of the cooling section 13 and a hollow tubular element 15 downstream of the mouthpiece body 14 at the mouthpiece end of article 1. In other examples, the hollow tubular element 15 may be omitted, and the mouthpiece body 14 may form the mouthpiece 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 mouthpiece end.

[0052] In this example, the cooling section 13 defines a void within the inlet. The void constitutes a chamber through which heated volatile components generated by the rod 2 of the aerosol-generating material flow. The cooling section 13 is hollow to constitute a chamber for aerosol accumulation, but is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article 1 is in use. The cooling section 13 results in a physical displacement between the rod 2 of the aerosol-generating material and the downstream portion of the inlet 3.

[0053] Preferably, the internal volume of the cooling section 13 is greater than 130 mm³. It has been found that providing a cavity of at least this volume enables improved aerosol formation. Such a cavity size provides sufficient space within the intake 2 to allow heated volatile components to cool, and thus allows the aerosol-generating material 2 to be exposed to a higher temperature than otherwise possible, which could result in an excessively warm aerosol. More preferably, the intake 3 has a cavity having an internal volume greater than 170 mm³, and even more preferably greater than 200 mm³, enabling further improvement of the aerosol. In some examples, the internal cavity contains a volume of about 130 mm³ to about 700 mm³, preferably about 160 mm³ to about 700 mm³. For example, the internal cavity may have a volume of about 170 mm³ to about 300 mm³.

[0054] The cavity can 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 can 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 mouthpiece from the high temperature of the aerosol-generating material 2 when heated.

[0055] 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. In addition, 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.

[0056] 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.

[0057] In this example, the cooling section 13 is formed from multiple layers of paper wound parallel to each other with their joints butted together to form a hollow tube. In this example, the first and second layers of paper make up a two-ply tube, but in other examples, three, four or more layers of paper can be used to form a three, four or more-ply tube. Other structures can be used, such as spirally wound layers of paper, cardboard tubes, tubes formed using a papier-mâché process, or molded or extruded plastic tubes.

[0058] 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 thickness of the wall of the hollow tube in the radial direction, excluding any surrounding material that can embed the hollow tube. The wall thickness of the cooling section 13 may be measured, for example, using a caliper.

[0059] 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.

[0060] In some embodiments, the wall thickness of the cooling section 13 is less than 1000 microns, preferably less than 500 microns.

[0061] The cooling section 13, the mouthpiece body 14, and the hollow tubular element 15 are connected by a binding packaging material 11.

[0062] In this example, article 1 is provided with first and second parallel rows of perforations 12 passing through the tip material 9, the binding packaging material 11, and the cooling section 13, allowing ventilation into the suction port 3 in the cooling section 13. In this case, the perforations 12 are formed as laser perforations at positions approximately 18 mm and 19 mm, respectively, from the downstream suction port end 3b of the suction port 3. In other examples, ventilation into the suction port 3 can be provided at other positions.

[0063] In this embodiment, the mouthpiece body 14 is a filter. However, it should be noted that in other examples, the mouthpiece body 14 may be provided without substantially filtering the inhalation of article 1.

[0064] 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 sheet material. In this example, the body 14 is formed by gathering the sheet material in a manner similar to that of a "crepe filter".

[0065] The hollow tubular element 15 is positioned at the suction 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.

[0066] 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. In addition, 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.

[0067] In this example, the tip paper 9 is wrapped around a portion of the rod 2 of the aerosol-generating material along the entire length of the mouthpiece 3 and has 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 rod 2 of the aerosol-generating material, but alternatively, it can extend 3 mm to 15 mm or 4 mm to 6 mm over the rod 2 to ensure a secure attachment between the mouthpiece 3 and the rod 2.

[0068] In this example, the rod 2 of the aerosol-generating material is wrapped in rod packaging material 10. The rod packaging material 10 may be, for example, paper or paper-backed foil packaging material. As described above, the connecting packaging material 7 surrounds substantially the entire length of the rod 7 of the aerosol-generating material such that the rod of the aerosol-generating material is surrounded by two packaging materials along substantially its entire length. Such a double-wrapped rod of the aerosol-generating material may have improved stiffness and / or rigidity. Preferably, this may make it possible to realize a rod of aerosol-generating material with a lower density while maintaining the desired level of stiffness.

[0069] In some examples, the rod packaging material 10 may contain a flavoring agent, an aerosol modifying additive, an aerosol forming agent, or an aerosol generating material.

[0070] 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 packaging material surrounding the component 4 and the rod 2 of aerosol-generating material. In article 1', the connecting packaging material 7 is replaced by a connecting packaging material 7' that surrounds the component 4 and a portion of the rod 2 of aerosol-generating material. The connecting packaging material 7' extends over only a portion of the rod 2 of aerosol-generating material. For example, the connecting packaging material 7' may extend over the rod of aerosol-generating material by about 3 mm to about 10 mm, for example, about 5 mm.

[0071] The connecting packaging material 7' may be the same as the connecting packaging material 7, except for its length. The connecting packaging material 7' has a length such that it does not extend over the entire length of the rod 2 of the aerosol generating material.

[0072] Figure 3A is a cross-sectional view of component 4 in Figures 1 and 2, passing through its line X-X'. Component 4 is shown separated from the rest of Article 1 and includes a material body 5 and packaging material 6. As shown, the material body 5 is formed from a crimped and gathered material sheet 8. The sheet 8 is gathered laterally to form a body 5 having a substantially cylindrical outer shape.

[0073] In some examples, the sheet 8 has a permeability of about 1,000 to about 50,000 cholesta units, and in some examples, about 5,000 to about 50,000 cholesta units. Such levels of permeability have been found to preferably result in components 4 that are less likely to form channels extending longitudinally through the body 5, as the material forming the body 5 is more uniformly distributed within the body 5. Thus, for a given weight of sheet material 8, increased permeability results in a higher suction resistance through the 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 achieve the desired suction resistance, and thus material can be saved.

[0074] In addition, 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. If the additive is applied to the sheet material 8 in liquid form, the increased permeability can also result in a more absorbent sheet material 8, meaning that a larger volume of the additive can be applied relative to a given weight of material.

[0075] 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.

[0076] Biodegradability can be measured according to the procedure described in ISO 14855-2:2018. The components described herein can achieve more than 50% biodegradability in 30 days when exposed to either freshwater or seawater.

[0077] 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 metal foil backed with paper.

[0078] In this example, the body 5 has a suction resistance of 0.5 mmH2O to 30 mmH2O, for example, 5 mmH2O to 25 mmH2O, or 10 mmH2O to 20 mmH2O. Preferably, the body 5 has a suction resistance of less than 10 mmH2O, for example, less than 8 mmH2O, or less than 6 mmH2O, or less than 5 mmH2O. In some examples, the suction resistance through the length of the body 5 is 0.5 mmH2O to 10 mmH2O. This suction resistance may be 1% to 30% of the suction resistance across the article, for example, less than 20%, less than 15%, or less than 10% of the suction resistance through the length of the article.

[0079] Aeration may be provided within the rod 2 of the aerosol-generating material such that the overall aeration level of 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%.

[0080] The suction resistance of body 5 (and other suction resistance and pressure drop measurements referenced herein) are measured according to the ISO standard method (ISO 6565:2015). Suction resistance refers to the "resistance to suction closure" when any ventilation area to the article or body is closed during measurement.

[0081] In some examples, the suction resistance through the length of body 5 is at least 5 mmH2O, or at least 7 mmH2O, or at least 8 mmH2O.

[0082] In some examples, the suction resistance through the length of the 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.

[0083] Article 1 in this example has a level of ventilation through which approximately 70% of the aerosol is drawn in.

[0084] In this example, the main body 5 is formed from a single gathered material sheet 8. However, in an alternative example, the main body 5 may be formed from multiple material sheets 8, and the gathers of the multiple material sheets 8 are brought together to form the main body 5. Each of the multiple material sheets may have the same or different properties, such as their dimensions, permeability, thickness, basis weight, and composition.

[0085] One or more sheets forming the main body 5 can have a total width of 100mm to 240mm, for example, 140mm to 200mm, before crimping. Such a width can achieve a good balance between the pressure drop across the length of the material body 5 and the hardness of the material body 5.

[0086] One or more sheets 8 forming the main body 5 can be formed from cellulose material. For example, one or more sheets can 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 can 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 can have an uncrimped 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.

[0087] In some examples, the sheet material 8 may include a metal foil, such as aluminum foil, or optionally, aluminum foil backed with paper. In other examples, the sheet material may include an aerosol-generating material, such as a paper-like reconstituted tobacco material, or an aerosol-generating film. Optionally, the aerosol-generating film may be laminated on a supporting material such as paper.

[0088] 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.

[0089] One or more sheets 8 can be crimped to increase the amount of sheet material that can be included in the body 5. At least one of the one or more sheets 8 extending through the body 5 may include a crimped sheet material formed to have a crimp pattern comprising a series of substantially parallel ridges and grooves.

[0090] In this example, the sheet material 8 is crimped before being formed into the body 5. For example, the sheet material 8 may be passed through a pair of crimping rollers. In this example, the first body 5 includes the crimped sheet material 8, which is formed having a crimp pattern comprising a series of substantially parallel ridges and grooves. The crimping may make it easier to gather the sheet material 8 to form the body 5. The crimping may also increase the width of the sheet material 8 that 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, and thus can increase the amount of moisture that can be absorbed by the body 5. Thus, the increased amount of condensate can be absorbed by the body 5, which can result in a more hygienic user experience when the article 1 is used in a non-combustible aerosol supply device.

[0091] In this example, the average spacing between adjacent raised areas of the sheet material 8 is greater than approximately 0.3 mm. In addition, in this example, the crimp amplitude is less than approximately 0.7 mm.

[0092] The crimp amplitude (also known as the "crimp coefficient") refers to the depth of the grooves formed in the sheet material 8 that forms the body by the crimp. That is, as shown in Figure 3B, crimping the sheet material 8 creates a number of peaks and valleys within the sheet material 8 when viewed from a first side of the sheet material 8, and the crimp amplitude "A" is the depth of the valleys measured from those peaks. The crimps may form a "zigzag" shape or another shape. In some examples, adjacent grooves in the crimped sheet material 8 are spaced apart at a distance of 0.3 to 2 mm, preferably 0.4 to 1 mm, or have a pitch "P". In some embodiments, adjacent grooves in the crimped sheet material are spaced apart at a distance of 0.1 to 3 mm, preferably 0.2 to 2 mm. In some embodiments, adjacent grooves in the crimped sheet material 10 are spaced apart 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 crimped sheet material are separated by a distance of at most 3 mm, for example, at most 2.5, 2, 1, 1.5, 0.7, 0.5, 0.2, or 0.1 mm.

[0093] For example, the sheet material 8 may have crimps with a crimp amplitude of less than 500 μm and crimps with a spacing between peaks (or valleys) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0094] In some embodiments, the sheet material 8 is heated when crimped. For example, the sheet material 8 may be passed between crimp rollers, one or both of which are heated. For example, one or both 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 crimp can be achieved by heating the rollers or by applying a higher level of pressure to the sheet material. For example, crimping can be applied using the roller surface at a temperature greater than 30°C, greater than 40°C, or greater than 50°C.

[0095] The bulk density of the main body 5 is approximately 0.1 mg / mm³. 3 ~about 0.25mg / mm 3 This can be achieved. In this example, the bulk 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 The bulk density of the material body can be measured by separating the body from the article and the surrounding plug wrap and / or chip paper, removing any embedded objects, but including any additives added to the sheet material 8. For the purpose of calculating the bulk density of the body, the contribution of axially extending hollow channels having a cross-sectional area greater than XX mm² is excluded from the calculation. The density may be calculated as bulk density 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 is measured inside the plug wrap 6.

[0096] In some examples, the material itself is formed not from a sheet material, but from another fibrous material such as cotton.

[0097] In some examples, an aerosol modifier or aerosol-forming agent may be added to the material forming the material body. For example, a flavoring agent 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 D and L enantiomers separately or in 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.

[0098] The use of acid within the material body 5 may be particularly preferable when the aerosol-generating material contains nicotine, because the acid can enable optimal protonation of nicotine in the resulting aerosol by, for example, changing the ratio of free base nicotine to protonated nicotine. Protonation of nicotine in the aerosol-generating material is understood to change the nicotine (gas):nicotine (fine particles / liquid) ratio by increasing the amount of nicotine present in the fine particles / liquid phase. The aerosol generated by the aerosol-generating material described herein delivers an appropriate amount of nicotine to the user.

[0099] In some examples, the main body 5 contains an aerosol-forming agent in an amount of 10% to 30% by weight.

[0100] In other examples, the material body 5 contains less than 5% by weight of an aerosol-forming agent.

[0101] 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 may be preferable 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, like a powder.

[0102] 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.

[0103] In this example, the upstream component 4 has a length of approximately 6 mm. In an alternative embodiment, the upstream 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.

[0104] The outer circumference of the upstream component 4 is substantially the same as the outer circumference of the rod 2 of the aerosol-generating material, so as to ensure a smooth transition between these components.

[0105] Although only a single material body 5 has been described with reference to the drawings, in alternative embodiments, Article 1 in Figures 1 and 2 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 upstream component 4, and may be formed from any material suitable for use in the articles described herein.

[0106] In some examples, the plug wrap 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.

[0107] Figure 4 is a side cross-sectional view of a further article 1, in which a second component 41 is provided downstream of the aerosol generating portion 2.

[0108] In some examples, the upstream component 4 and the second component 41 define a cavity between them. The cavity may be appropriately filled with granular aerosol-generating material. Placing the second component 41 immediately downstream of the rod 2 of aerosol-generating material can help prevent the aerosol-generating material from falling into the cooling section 13, especially when the aerosol-generating material is provided in the form of fine particles.

[0109] In some examples, the second component 41 is substantially the same as the upstream component 4. Appropriately, the second component 41 may include any material or material configuration as described above with respect to the upstream component 4.

[0110] In some examples where the second component 41 is located downstream of the aerosol generating portion, the length of the upstream component 4 may be shortened compared to the length of the upstream component 4 in the examples of Figures 1 and 2, in order to accommodate the extra length of the second component 41 without changing the overall length of article 1”. In other examples, the upstream component 4 may have the same length as described in relation to Figures 1 and 2, and the length of the mouthpiece body 14 or the cooling section 13 may be shortened.

[0111] In other examples, the second component 41 may differ from the upstream component 4. For example, the main body 51 may be formed from a sheet material different from the sheet material on which the main body 5 is formed, for example, having a different material composition, or a different basis weight, width, or crimp pattern.

[0112] In some examples, the downstream body 51 may include, for example, an aerosol modifying additive that is coated onto the sheet material on which the body 51 is formed, or an aerosol modifying additive that is embedded in the body 51 as a capsule, microcapsule, or thread filled with the aerosol modifying additive.

[0113] For example, one or more capsules incorporated into the body 51 in the form of multiple capsules, such as microcapsules, or a single capsule, can be thermally and / or pressure-activated to release their capsule payloads. In some embodiments, one or more capsules may be configured to release their payloads, for example, in the form of a liquid payload, when exposed to temperatures greater than 100 degrees Celsius or greater than 150 degrees Celsius. Alternatively or additionally, one or more capsules may be configured to release their payloads when exposed to force applied to the capsules, for example, by a consumer gripping the material body 51. In any case, since the material body 51 is located adjacent to the aerosol-generating material, when the aerosol-generating material is heated, the material body 51 is exposed to heat, and as a result, the capsule payloads can be efficiently aerosolized and delivered to the consumer.

[0114] In this example, the second component 41 includes an aerosol modifying additive. In this example, the aerosol modifying additive is provided in the form of an aerosol generating film laminated on the sheet material on which the main body 51 is formed. The main body 51 is configured as described with respect to the main body 5, except that the sheet material in this case is a laminated material including an aerosol generating film laminated on a paper support material.

[0115] In other examples, the aerosol-generating film may be provided in the form of a strip, and the strip is gathered to form the main body 51, with the sheet material forming the main body.

[0116] In other examples, the main body 51 may be omitted, and an aerosol modifying additive may be provided downstream of the rod 2 of the aerosol generating material. For example, a thermally activated capsule may be embedded downstream of the rod 2 of the aerosol generating material.

[0117] Figure 5 is a side cross-sectional view of a further article 1'''. Article 1''' is substantially the same as article 1, except that a tubular element 16 is provided at the upstream end of article 1 instead of the upstream component 4 in Figure 1. Preferably, by providing the tubular element 16 at the upstream end of article 1''', the aerosol-generating portion can be moved away from the distal end of the cavity of the aerosol-supplying device during use. The dimensions of the tubular element 16 may be appropriately configured so that the aerosol-generating portion 16 is displaced during use toward the portion of the aerosol-supplying device where improved heating of the aerosol-generating material is found. In some examples, the tubular element 16 has a length of 5% to 13% of the length of article 1'''.

[0118] In some examples, the tubular element 16 has a wall thickness greater than 1 mm. For example, the tubular element 16 can have a wall thickness of 1 mm to 2 mm. In this example, the wall thickness of the tubular element 16 is approximately 1.5 mm.

[0119] In this example, the tubular element 16 is formed from paper. In some examples, the tubular element 16 may be formed in the same way as the cooling section 13. In this example, the tubular element 16 and the cooling section 13 may have the same wall thickness. Advantages - It is manufactured by forming a continuous rod from tobacco and tube portions and alternating the cuts. In other examples, the tubular element 16 has a greater wall thickness than the cooling section 13, for example, to prevent the tobacco material from falling out.

[0120] In some examples, the tubular element 16 may be embedded in a section formed from a material body, such as a gathered sheet material. For example, the material body 5 may include the tubular element 16.

[0121] In this example, the tubular element 16 has the same outer diameter as the rod 2 of the aerosol-generating material. In other examples, the tubular element 16 may have a smaller outer diameter than the rod 2 of the aerosol-generating material, for example, if the tubular element 16 is embedded in the material body.

[0122] In examples where the tubular element 16 is embedded in the material body, the axially extending hollow channel defined by the tubular element 16 may appropriately have a diameter of at least 0.5 mm, or at least 0.75 mm, or at least 1 mm, or at least 1.5 mm, or at least 2 mm.

[0123] In some examples, the rod of aerosol-generating material may include axially positioned aerosol-modifying additives, such as capsules or microcapsules, or threads filled with aerosol-modifying additives. In some examples, a tubular element 16 can guide aerosols through the axial portion of the rod 2 of the aerosol-generating material during use, thereby enhancing the delivery of the axially positioned aerosol-modifying additives. One or more capsules incorporated into the rod of aerosol-generating material in the form of multiple capsules, such as microcapsules, or a single capsule, can be thermally and / or pressure-activated to release the capsule payload. In some embodiments, one or more capsules may be configured to release their payloads, for example, in the form of a liquid payload, when exposed to temperatures greater than 100 degrees Celsius or greater than 150 degrees Celsius. Alternatively or additionally, one or more capsules may be configured to release their payloads when exposed to force applied to the capsules, for example, by a consumer gripping the rod of aerosol-generating material. In any case, since the rod of aerosol-generating material is exposed to heat, the capsule payloads can be efficiently aerosolized and delivered to the consumer.

[0124] Figure 6 is a side cross-sectional view of a further article 1''. Article 1'' comprises an upstream component 4 at the upstream end of the article and a tubular element 16 positioned between the upstream component 4 and the rod 2 of the aerosol-generating material. The mouthpiece 3 of article 1'' is substantially the same as the mouthpiece of article 1'.

[0125] In this example, article 1"" is provided with first and second parallel rows of perforations 18 passing through the packaging material 7 and the tubular element 16, and ventilation is provided inside article 1"" upstream of the rod 2 of the aerosol generating material.

[0126] The perforations 18 can result in 0% to 20% of the total airflow to article 1''. Preferably, by providing an upstream component 4 at the upstream end of the article and a vent tubular element 16 upstream of the rod 2 of the aerosol-generating material, the amount of condensate released from the upstream end of article 1'' during use can be reduced. This can provide hygienic advantages to the use of article 1'' in a non-combustible aerosol supply system.
