[Figure 5]This is a side cross-sectional view of an article for use in an aerosol supply system, including further components downstream of the aerosol generation section. [Modes for carrying out the invention]

[0028] In the figures described herein, similar reference numerals are used to indicate equivalent features, articles, or components.

[0029] Figure 1 is a side cross-sectional view of article 1 for use in an aerosol supply system. In this case, article 1 is for use in a non-combustible aerosol supply system.

[0030] Article 1 includes an aerosol generating section, in this case a cylindrical rod of aerosol generating material 2, and a suction port 3 located downstream of the aerosol generating section and connected to it. Article 1 can be used in a heating device to form a non-combustible aerosol supply system. In other examples, Article 1 may include its own heat source to form an aerosol supply system without requiring a separate aerosol supply device.

[0031] The article also includes a component 4 at its upstream end. Component 4 includes a body 5 of material wrapped in component packaging material 6.

[0032] In this case, the component packaging material 6 is paper plug wrap. In some examples, the component packaging material 6 is non-combustible. In some examples, the component packaging material 6 can be formed from paper that has been treated, coated, or laminated with another material to be non-combustible, such as foil-backed paper. The structure of component 4 is described in more detail below with reference to Figure 2A.

[0033] In this example, a rod of aerosol-generating material 2 is packaged in a first packaging material 10. In this example, a rod of aerosol-generating material 2 contains tobacco material. The tobacco material can be appropriately provided in the form of shredded tobacco, dry ice-inflated tobacco (DIET), strands and / or strips of reconstituted tobacco, or granular tobacco material. Optionally, the aerosol-generating material may include a mixture of tobacco material and another form of aerosol-generating material. In some examples, the aerosol-generating material may be a particulate aerosol-generating material. Examples of particulate aerosol-generating materials include granular plant material, granular tobacco material, granular non-tobacco plant material, and microcapsules of aerosol-generating material. For example, the aerosol-generating material may include tobacco material and beads or granules of aerosol-generating material such as gel or aerosol-generating film components, capsules, or microcapsules.

[0034] Capsules or microcapsules can be thermally and / or pressure-activated to release their contents. In some embodiments, capsules or microcapsules may be configured to release their contents, for example, in the form of a liquid, when exposed to temperatures above 100°C or above 150°C. Alternatively or additionally, capsules or microcapsules may be configured to release their contents when subjected to a force applied to them.

[0035] In other examples, the aerosol-generating material 2 may be a non-tobacco plant material optionally containing the active material or substance described herein.

[0036] In some examples, the aerosol-generating material contains 10% to 30% of the aerosol-forming agent on a dry weight basis.

[0037] The rod of aerosol generating material 2 contains 50 mg / cm³ 3 ~350 mg / cm³ 3 A range, for example, 100 mg / cm³ 3 ~300 mg / cm³ 3 , or 150 mg / cm³ 3~250 mg / cm³ 3 , or 180 mg / cm³ 3 ~220 mg / cm³ 3 , or 100 mg / cm³ 3 ~200 mg / cm³ 3 It may have a bulk density of . In some examples described herein, the aerosol-generating material is supplied in a cavity rather than as a rod, and the density of the aerosol-generating material in the cavity is cm² of the cavity. 3 It may be less than 100 mg per unit. For example, the bulk density of the aerosol-generating material in the cavity is the cm³ of the cavity. 3 5mg per unit and the cavity commercial 3 Between 90mg per unit, for example, the cm of the cavity 3 10mg per unit and the cavity commercial 3 Between 80mg per unit, or the cm of the cavity 3 15g per serving and the cavity commercial 3 It can be between 70 mg per unit. In this example, the rod of the aerosol-generating material contains approximately 265 mg / cm³. 3 It has bulk density.

[0038] The bulk density of the aerosol-generating material 2 can be calculated by obtaining the total weight of the rod 2, excluding the weight of the packaging material around the rod 2 and any other components that are not the aerosol-generating material, and then dividing the resulting weight by the volume defined by the inner surface of the packaging material 10.

[0039] The main body 5 of the material, positioned upstream of the aerosol generation section, can be arranged to hold the aerosol generation material 2 within the rod.

[0040] In this example, the intake 3 includes a cooling section 13 located downstream of the rod of the aerosol-generating material 2. In this example, the cooling section 13 is in contact with the rod of the aerosol-generating material 2. In other examples, additional components may be provided between the rod of the aerosol-generating material 2 and the cooling section 13. In this example, the cooling section 13 includes a cavity, but other forms of cooling devices may be used. In this example, the cooling section 13 is formed as a tubular element defining the outer wall of the cavity.

[0041] In some examples, the inner surface of the first packaging material 10 defines a cavity into which the aerosol-generating material is provided. The cavity is at least 100 mm 3 It has a volume and may be at least partially filled with particulate aerosol-generating material.

[0042] The first packaging material 10 may be, for example, paper or foil packaging material backed with paper.

[0043] In some examples, the rod of the aerosol-generating material 2 is surrounded by two or more packaging materials over at least a portion of its length to provide increased stability and / or rigidity to the rod of the aerosol-generating material 2. In this example, the rod of the aerosol-generating material 2 is surrounded by a first packaging material 10 and a connecting packaging material 7. In some examples, the connecting packaging material 7 is placed over at least two-thirds of the length of the aerosol-generating portion, for example, at least two-thirds of the rod of the aerosol-generating material 2 in this case.

[0044] The rod of the aerosol generating material 2 may have a length L. The portion of the length of the rod of the aerosol generating material 2 enclosed by the first packaging material 10 and the connecting packaging material 7 may be at least one-third of the length L, or at least half of the length L, preferably at least two-thirds of the length L. Preferably, the entire length or total length L of the rod of the aerosol generating material 2 is enclosed by at least the first packaging material 10 and the connecting packaging material 7.

[0045] At least one of the first packaging material 10 and the connecting packaging material 7 may contain an aerosol-generating material and / or an aerosol modifier. The first packaging material 10 may, for example, contain an aerosol-generating material, while the connecting packaging material 7 may substantially not contain an aerosol-generating material. This may be the case, for example, when the first packaging material 10 is provided inside the connecting packaging material 7.

[0046] In this case, the connecting packaging material 7 is wrapping paper. In other examples, the connecting packaging material 7 may be foil packaging material backed with paper, or metal foil.

[0047] 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 can be determined according to test method T 494.

[0048] In some examples, the connecting packaging material 7 has a permeability of at least 3 coresta units. In some examples, the connecting packaging material 7 has a permeability of at least 5 coresta units, at least 10 coresta units, or at least 20 coresta 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, together with any intermediate layer of adhesive, is at least 25 coresta units, or at least 30 coresta units, or at least 50 coresta units. The combined permeability of the rod packaging material 10 and the connecting packaging material 7, together with any intermediate layer of adhesive, can be determined by disassembling 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.

[0049] 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 provided 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.

[0050] In some examples, the rod of aerosol-generating material may be surrounded by further packaging material provided inside the first packaging material 10.

[0051] In some examples, the first packaging material 10 may include, for example, a coating of an aerosol-generating film on the inner surface of the packaging material. The aerosol-generating film may be laminated on the inner surface of the first packaging material 10. Additionally or alternatively, the first packaging material 10 may be impregnated with an aerosol-forming agent or an aerosol-modifying agent.

[0052] Providing an innermost first packaging material 10 containing an aerosol-generating material or aerosol-forming agent may help enhance or complement the flavor or composition of the aerosol provided by article 1.

[0053] Providing an outer packaging material, such as a connecting packaging material 7, placed on top of an inner packaging material containing an aerosol-generating material or aerosol-forming agent, can provide the dual benefit of giving the rod 2 additional strength, while also preventing the aerosol-generating material or aerosol-forming agent on the inner packaging material from coming into contact with the user's fingers or the inside of the heating device.

[0054] In this example, the tip paper 9 is wrapped around the entire length of the mouthpiece 3 and over a portion of the rod of the aerosol-generating material 2, 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 of the aerosol-generating material 2, 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.

[0055] Component 4 is connected to the rod of aerosol-generating material 2 by a connecting packaging material 7. In this case, the connecting packaging material 7 includes paper packaging material. In other examples, the connecting packaging material 7 may be paper-backed foil packaging material or metal foil. Similarly, in other examples, component packaging material 6 may be metal foil, optionally paper-backed metal foil.

[0056] The connecting packaging material 7 is bonded to both the component 4 and the rod of the aerosol-generating material 2. At least a portion of the inner surface of the connecting packaging material 7 is covered with a layer of adhesive. Surprisingly, it has been found that applying a reduced amount of adhesive to the connecting packaging material 7 can result in the formation of an improved aerosol. 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 in strips to the connecting packaging material 7 so that the rest of the connecting packaging material 7 does not have any adhesive at all before the component 4 and the tobacco rod 2 are combined. If the connecting packaging material 7 with the adhesive strips is wrapped around the component 4 and the rod of the aerosol-generating material 2, then the portion of the component 4 and the rod of the aerosol-generating material 2 do not need to have adhesive. The adhesive strips 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 during manufacturing, which can result in higher tensile strength for the connecting packaging material 7, thus effectively improving the ease of manufacturing the article 1.

[0057] Other means may 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 various patterns, such as a dot matrix.

[0058] Preferably, at least a portion of the inner surface area of ​​the connecting packaging material 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 packaging material 7 is free of adhesive.

[0059] 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 can be determined according to test method T 494.

[0060] 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 first packaging material 10 and the connecting packaging material 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 first packaging material 10 and the connecting packaging material 7, together with any intermediate layer of adhesive, can be determined by disassembling 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 first packaging material 10, the connecting packaging material 7, and any intermediate layer of adhesive, in accordance with ISO 2965:2019.

[0061] Preferably, at least one of the component packaging material 6 and the connecting packaging material 7 includes a non-combustible material, preferably a metal foil or a combustion-inhibiting layer or coating. Preferably, by providing an article in which the upstream end of the article is surrounded by a non-combustible material such as a metal foil or a combustion-inhibiting layer or coating, it is possible to prevent the user of the article from setting it on fire like a conventional cigarette when the article is not intended for such use.

[0062] In some examples, the constituent packaging material 6 has a basis weight of approximately 25 gsm to approximately 70 gsm, for example, approximately 27 gsm, 36 gsm, approximately 41 gsm, or approximately 44 gsm.

[0063] The flammability of paper packaging materials for use with articles can be determined in accordance with ISO 5729:2021.

[0064] As will be explained in more detail below, providing a component 4 at the upstream end of article 1 can bring several advantages. For example, the stability of article 1 in use can be improved by preventing the aerosol-generating material from detaching from the upstream end of the article. If component 4 includes a body of material having a suction resistance of about 1% to 30% of the suction resistance of article 1, this can also result in greater consistency of suction resistance between articles, as the contribution of the rods of the aerosol-generating material 2 to the overall suction resistance of article 1 is relatively small. Preferably, the relatively high suction resistance of component 4 can make the overall suction resistance of article 1 less susceptible to fluctuations in the suction resistance of the rods of the aerosol-generating material 2.

[0065] In this case, component 4 is adjacent to the upstream end of the rod of the aerosol-generating material 2. In other examples, two or more components may be provided upstream of the rod of the aerosol-generating material. 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 rod of the aerosol-generating material 2.

[0066] 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 having a circumference greater than 19 mm. This has been found to provide a circumference sufficient to produce an improved and sustained aerosol over a typical aerosol-generating period preferred by consumers. When the article is heated, heat is transferred through the rod of aerosol-generating material 2, 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 heating and aerosolization 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 effective aerosol delivery and efficient heating at the same time.

[0067] The outer circumference of the mouthpiece 2 is substantially the same as the outer circumference of the rod of the aerosol-generating material 3, 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.

[0068] In this example, the mouthpiece 3 also includes a mouthpiece body 14 downstream of the cooling section 13 and a hollow tubular element 15 downstream of the mouthpiece body 14 at the mouth end of article 1. In other examples, the hollow tubular element 15 may be omitted, and the mouthpiece body 14 may form the mouth 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 a body of additional material may be provided at the mouth end.

[0069] In this example, the cooling section 13 defines a void within the inlet. The void provides a chamber through which heated volatile components generated by the rod of the aerosol-generating material 2 flow. The cooling section 13 is hollow to provide 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 provides physical displacement between the rod of the aerosol-generating material 2 and the downstream portion of the inlet 3.

[0070] Preferably, the internal volume of the cooling section 13 is 130 mm 3 Larger. It has been found that providing a cavity of at least this volume enables improved aerosol formation. Since aerosol-generating materials can produce excessively warm aerosols, such a cavity size provides sufficient space within the mouthpiece 2 to allow the heated volatile components to cool, and thus allows the aerosol-generating material 2 to be exposed to a higher temperature than otherwise possible. More preferably, the mouthpiece 3 is 170 mm 3 Larger than that, even more preferably 200 mm 3 It features a cavity with a larger internal volume, allowing for further improvement of aerosols. In some examples, the internal cavity is approximately 130 mm 3 ~about 700mm 3 Preferably about 160 mm 3 ~about 700mm 3 This includes the volume of the internal cavity. For example, the internal cavity is approximately 170 mm². 3 ~about 300mm 3 It can have a volume of .

[0071] The cavity may be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile components that first enter the upstream end of the cavity and the heated volatile components that then exit the downstream end of the cavity. Preferably, the cavity may be configured to provide a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius between the heated volatile components that first enter the upstream end of the cavity and the heated volatile components that then exit the downstream end of the cavity. This temperature difference along the length of the cavity can protect elements downstream of the cavity that are susceptible to temperature fluctuations at the mouthpiece from the high temperature of the aerosol-generating material 2 when heated.

[0072] 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.

[0073] 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.

[0074] 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 are provided in a double tube, but in other examples, three, four or more layers of paper can be used to form three, four or more double tubes. Other configurations 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.

[0075] 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 any surrounding material that can embed the hollow tube. The wall thickness of the cooling section 13 can be measured, for example, using a caliper.

[0076] 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.

[0077] In some embodiments, the wall thickness of the cooling section 13 is less than 1000 microns, preferably less than 500 microns.

[0078] The cooling unit 13, the suction port body 14, and the hollow tubular element 15 are connected by the packaging material 11.

[0079] In this example, article 1 is provided with first and second parallel rows of perforations 12 passing through the tip material 9 and the cooling section 13, providing ventilation into the suction port 3. In this case, the perforations 12 are formed as laser perforations at positions approximately 18 mm and 19 mm, respectively, from the downstream end 3b of the suction port 3. In other examples, ventilation into the suction port 3 can be provided at other positions.

[0080] 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 substantial filtration of the aerosol generated by article 1.

[0081] 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 to form the body 14 in a manner similar to that of a "crepe filter".

[0082] 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.

[0083] Preferably, in order to improve the biodegradability and sustainability of the article, each component used to form the article, with the exception of aerosol-generating materials, is formed substantially from paper.

[0084] 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.

[0085] Figure 2A is a cross-sectional view of component 4 in Figure 1 through its line X-X'. Component 4 is shown separated from the rest of article 1 and includes a body 5 of material and component packaging material 6. As shown, the body 5 of material is formed from a pleated and gathered sheet 8 of material. The sheet 8 is gathered laterally to form a body 5 having a substantially cylindrical outer shape.

[0086] In some examples, the sheet 8 has a permeability of approximately 1,000 to 50,000 cholesta units, and in other examples, approximately 5,000 to 50,000 cholesta units. Such levels of permeability have been favorably found to result in a more uniform distribution of the material forming the body 5, leading to a component 4 that is less likely to form longitudinal channels through the body 5. Thus, for a given weight of sheet material 8, increased permeability results in 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 therefore material can be saved.

[0087] 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 lead to 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 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.

[0088] The permeability of the material sheet 7 can be measured according to the international standard ISO 2965:2019, as is known to those skilled in the art.

[0089] Biodegradability can be measured according to the procedure described in ISO 14855-2:2018. When components such as those described herein are exposed to either freshwater or seawater, It can achieve over 50% biodegradation in 30 days.

[0090] In other examples, the sheet material may have low porosity or be non-porous, for example, less than 1000 cholesta units or less than 100 cholesta units, for example 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.

[0091] In this example, the main body 5 has a suction resistance of 0 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. This suction resistance may be 1% to 30%, for example, 5% to 25%, or 10% to 20%, of the suction resistance across the article. Preferably, by providing a component 4 upstream of the rod of the aerosol-generating material 2, having a suction resistance of 5% to 25% of the suction resistance across the article, the relative contribution of the rod of the aerosol-generating material to the overall suction resistance of the article is reduced. As a result, the overall suction resistance of the article 1 is less susceptible to fluctuations in the suction resistance of the rod of the aerosol-generating material that may occur due to the organic properties of the tobacco material, and it is also possible to bring a higher level of ventilation into the rod of the aerosol-generating material while keeping the overall suction resistance across the length of the article 1 at an acceptable level. Aeration may be introduced into the rod of the aerosol-generating material 2 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%.

[0092] 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 closure to suction" when any ventilation area to the article or body is closed during measurement.

[0093] In some examples, the suction resistance of body 5 is at least 5 mmH2O, or at least 7 mmH2O, or at least 8 mmH2O.

[0094] 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.

[0095] Article 1 in this example has a permeability level of approximately 70% of the aerosol drawn through Article 1. In other examples, Article 1 can preferably have a permeability level of 20% to 60%. These values ​​can provide a good balance between promoting aerosol formation, which can be increased by permeability, and maintaining the concentration of the aerosol components at a desired level.

[0096] In this example, the body 5 is formed from a single sheet 8 of gathered material. However, in an alternative example, the body 5 may be formed from multiple sheets 8 of material 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.

[0097] In other examples, the main body 5 of the material may be formed from gathered strips of sheet material. For example, the sheet material 8 may be cut into strips before being formed into the main body 5.

[0098] 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 unpleated 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.

[0099] 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 tobacco material reconstituted with paper, or an aerosol-generating film. Optionally, the aerosol-generating film may be laminated on a supporting material such as paper.

[0100] The material body 5 may have a weight of approximately 5 mg to approximately 15 mg per 1 mm of length, or approximately 8 mg to approximately 12 mg per 1 mm of length, or approximately 10 mg per 1 mm of length. In some examples, the material body has a weight of approximately 6 mg per 1 mm of length.

[0101] One or more sheets 8 forming the main body 5 of the material may have a total width of 100mm to 240mm, for example, 140mm to 200mm, before any pleating. Such a width can result in a good balance between the pressure drop through the length of the main body 5 of the material and the hardness of the main body 5 of the material.

[0102] The amount of sheet material that can be included in the body 5 can be increased by pleating one or more sheets 8. At least one of the one or more sheets 8 extending through the body 5 may include pleated sheet material formed to have a pleat pattern comprising a series of substantially parallel ridges and grooves.

[0103] In this example, the sheet material 8 is pleated before being formed into the body 5. For example, the sheet material 8 may be passed through a pair of pleating rollers. In this example, the first body 5 includes the pleated sheet material 8, which is formed to have a pleated pattern comprising a series of substantially parallel ridges and grooves. Pleating makes it easier to gather the sheet material 8 to form the body 5. Pleating can 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.

[0104] In this example, the average spacing between adjacent ridges in sheet material 8 is greater than approximately 0.3 mm. Also, in this example, the fold amplitude is less than approximately 0.7 mm.

[0105] The pleat amplitude (also known as the "pleat coefficient") refers to the depth of the grooves formed by the pleating process within the sheet material 8 that forms the main body. That is, as shown in Figure 2B, pleating the sheet material 8 creates multiple peaks and valleys within the sheet material 8 when viewed from a first side of the sheet material 8, and the pleat amplitude "A" is the depth of the valleys measured from those peaks. The pleating process can form a "zigzag" shape or another shape. In some examples, adjacent grooves in the pleated 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 pleated 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 pleated 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 pleated 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. For example, the sheet material 8 may have pleats with a pleat amplitude of less than 500 μm and a spacing between peaks (or valleys) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0106] In some embodiments, the sheet material 8 is heated when it is pleated. For example, the sheet material 8 may be passed between pleating 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 can also be varied. A higher level of pleating can be achieved by heating the rollers / multiple rollers or by applying a higher level of pressure to the sheet material. For example, pleating may be applied using roller surfaces with temperatures above 30°C, above 40°C, or above 50°C.

[0107] The average density of the main body 5 is approximately 0.1 to 0.25 mg / mm³. 3 This is possible. In this example, the density of the main body 5 of the material is approximately 190 mg / cm³. 3 That is the case. In some examples, the density of the material body is approximately 50 to 400 mg / cm³. 3 , about 100~300mg / cm 3 , about 150~200mg / cm 3 Or approximately 160-190 mg / cm³ 3 In some embodiments, the main body 5 contains at least 100 mg / cm³. 3 , 120 mg / cm³ 3 Or 150 mg / cm³ 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, but including any additives added to the sheet material 8. The density can 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 measured inside the plug wrap 6.

[0108] In some cases, the main body of the material is formed not from a sheet material, but from another fibrous material such as cotton.

[0109] In some examples, an aerosol modifier or aerosol-forming agent can be added to the material forming the body of the material. For example, a flavor carrier, an active substance as defined herein such as nicotine, and / or glycerol may be coated onto the sheet material 8 before forming the body 5 of the material. In some examples, the body 5 of the material includes an aerosol-forming film containing lactic acid, as described, for example, in International Publication No. 2021 / 105449.

[0110] In some examples, the main body 5 contains an aerosol-forming agent in an amount of 10% to 30% by weight.

[0111] In other examples, the main body of the material 5 contains an aerosol-forming agent in an amount of less than 5% by weight.

[0112] In other examples, the main body of the material 5 includes a combustion suppression material, for example, a combustion suppression salt and aerosol-generating film, or a salt gel, as described in International Publication No. 2020 / 183163. In some embodiments, the combustion suppression salt is incorporated into an amorphous solid material to form a salt gel as referred to herein. This means that the combustion suppression salt is contained within the amorphous solid composition. For example, during the preparation of the amorphous solid material, a liquid precursor of the amorphous solid material is mixed with the combustion suppression salt. This distributes the combustion suppression salt throughout the resulting amorphous solid material. In some embodiments, the distribution of the combustion suppression salt is uniform throughout the amorphous solid, which may be preferable because the combustion suppression effect is effective throughout the entire material. The combustion suppression salt may be added in the form of a solution or suspension. Alternatively, the combustion suppression salt may be added to the liquid precursor in solid form, for example, in the form of fine particles such as a powder.

[0113] In other embodiments, the combustion suppression 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 suppression salt is applied to the surface of the amorphous solid material to deposit the combustion suppression salt on the surface of the amorphous solid material.

[0114] In this example, component 4 has a length of approximately 6 mm. In an alternative embodiment, 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.

[0115] The outer circumference of component 4 is substantially the same as the outer circumference of the rod of the aerosol-generating material 2, so that the transition between these components is smooth.

[0116] Although only a single-material body 5 has been described with reference to the drawings, in alternative embodiments, articles 1, 1' in Figures 1 to 3 may include additional sections, such as additional material bodies, or other sections, such as tubular sections. Additional sections may be located 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.

[0117] Figure 3 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 packaging material connecting the components of the article. In this case, the mouthpiece 3 comprises a cooling section 13, a mouthpiece body 14, and a hollow tubular element 15, connected by packaging material 11, and is joined to the rod and components 4 of the aerosol generating material 2 by additional packaging material 17 extending along substantially the entire length of article 1'. In this example, the additional packaging material 17 includes paper. The additional packaging material 17 may be chip paper, such as the chip paper 9 used in article 1 in Figure 1.

[0118] Figure 4 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 the length of component 4' is shorter in this example compared to the length of component 4 in Figure 1, and the additional component 41 is located upstream of component 4'. In this example, each of components 4' and 41 has a length of 3 mm such that the combined length of components 4' and 41 is the same as that of component 4 in Figure 1. In other examples, components 4' and 41 can have any suitable length as described above with respect to component 4.

[0119] In this example, the material body 5' of the downstream component 4' may preferably both contain the aerosol-forming agent or aerosol modifier described herein. By providing the aerosol-forming agent or aerosol modifier within the body 4', an improved aerosol can be produced.

[0120] By providing components 4' and 41 adjacent to the upstream end of article 1", preferably the rod of the aerosol-generating material 2 can be displaced from the distal end of the heating configuration 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 positioned at the upstream end of article 1, which is configured to function as a heat exchanger, thereby suitably improving heat transfer to the air flowing into article 1". This can be achieved, for example, by providing component 41 including a body 51 formed from a strip of metal foil, such as aluminum foil.

[0121] 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 modifier, the aerosol generated by the article in use can be particularly improved. The combined effect of the upstream component 41 improving the heating of the air passing through the article 1" and the downstream component 4' providing an additional aerosol-forming agent or aerosol modifier can preferably improve the consumer experience of the article 1" in use.

[0122] In this example, the additional component 41 includes a material body 51. The material body 51 may be formed from any material described with respect to the material body 5 in any suitable manner. 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.

[0123] Components 4' and 41 are respectively surrounded by the first packaging materials 6' and 61, as described above in relation to Figure 1, and joined together by the connecting packaging material 7. In an alternative example, components 4' and 41 may be joined together by further packaging materials before being joined with the rod of aerosol-generating material by the connecting packaging material 7.

[0124] Figure 5 is a side cross-sectional view of a further article 1''', in which a second or additional component 411 is provided downstream of the aerosol-generating portion 2. In some examples, the first component 4 and the second component 411 define a cavity between them. The cavity may be appropriately filled with particulate or fine-particle aerosol-generating material. In this example, the additional or second component 411 is substantially the same as the first upstream component 4. In other examples, the upstream component 4 and the second component 411 may be different. For example, the body 5 of the upstream component 4 may be formed from a sheet material containing metal foil, and the body 511 of the second component 411 may be formed from a sheet material containing an aerosol-generating agent or aerosol modifier.

[0125] In some examples, if the additional component 411 is located downstream of the aerosol-generating section, the length of the first component 4 can be shortened to accommodate the extra length of component 411 without changing the overall length of article 1''. In other examples, the additional component 411 may have the same length as described in relation to Figures 1 and 3, and the length of the mouthpiece body 14 or the cooling section 13 can be shortened. Placing the body 411 immediately downstream of the rod of the aerosol-generating material 2 can help prevent the aerosol-generating material from falling into the cooling section 13, especially when the aerosol-generating material is provided in particulate form.

[0126] In this example, the body 511 of the material of the second component 411 contains an aerosol-forming agent. In this example, the aerosol-forming agent is applied to the sheet material forming the body 511. Placing the body 511 downstream of the rod of the aerosol-generating material 2 can preferably improve the aerosol generated from article 1''' by increasing the aerosol-forming agent content at the start of the service period, and can prevent the aerosol-forming agent in the rod of the aerosol-generating material 2 from being completely released during the service period. Preferably, this can reduce the variation in the aerosol profile between the initial and subsequent fume extractions of article 1''' during use.

[0127] As used herein, the term “delivery system” is intended to encompass a system for delivering a substance to a user, and includes the following: Non-combustible aerosol supply systems that release compounds from aerosolizable materials without burning the materials, such as hybrid systems that generate aerosols using a combination of e-cigarettes, tobacco heating products, and aerosolizable materials.

[0128] According to this disclosure, a “flammable” aerosol supply system is one in which the aerosolizable material (or its components) that constitutes the aerosol supply system is burned or incinerated in order to facilitate delivery to the user.

[0129] According to this disclosure, a “non-combustible” aerosol supply system is a system in which the aerosolizable material (or its components) constituting the aerosol supply system is not burned or incinerated in order to facilitate delivery to the user.

[0130] In the embodiments described herein, the delivery system may be a non-combustible aerosol supply system, such as a combustible aerosol supply system or a powered non-combustible aerosol supply system.

[0131] The non-combustible aerosol delivery systems described herein may be e-cigarettes, also known as vaping devices or electronic nicotine delivery systems (ENDs), but it should be noted that the presence of nicotine in the aerosolizable material is not a requirement.

[0132] The non-combustible aerosol supply system described herein may be a tobacco heating system, also known as a non-combustible heating system.

[0133] The non-combustible aerosol supply system described herein is a hybrid system that generates an aerosol using a combination of aerosolizable materials, one or more of which may be heated.

[0138] In one embodiment, the aerosol-generating component is a heater capable of interacting with an aerosolizable material to form an aerosol by releasing one or more volatile substances from the aerosolizable material. In one embodiment, the aerosol-generating component can generate an aerosol from an aerosolizable material without heating. For example, the aerosol-generating component may generate an aerosol from an aerosolizable material without applying heat to it, for example, by one or more of vibration, mechanical, pressurizing, or electrostatic means.

[0139] In one embodiment, the aerosolizable material may comprise an active material, an aerosol-forming material, and optionally one or more functional materials. The active material may comprise nicotine (optionally contained in tobacco or tobacco derivatives), or one or more other non-olfactory physiologically active materials. The non-olfactory physiologically active materials are materials included in the aerosolizable material to achieve physiological responses other than olfaction.

The region for receiving the aerosolizable material may be a storage region for storing the aerosolizable material. For example, the storage region may be a reservoir. In one embodiment, the region for receiving the aerosolizable material may be separate from the aerosol generation region or may be combined with the aerosol generation region.

[0143] Aerosolizable materials, also referred to herein as aerosol-generating materials, are materials that can generate aerosols when energy is applied, for example, by heating, irradiation, or any other method. Aerosolizable materials may be in the form of a solid, liquid, or gel, which may or may not contain nicotine and / or flavoring agents.

[0144] The aerosol-generating material may include a binder such as a gelling agent and an aerosol-forming agent. Optionally, a delivered substance and / or filler may also be present. Optionally, a solvent such as water may also be present, and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. In some embodiments, the aerosol-generating material is substantially free of plant-based materials. In particular, in some embodiments, the aerosol-generating material is substantially free of tobacco.

[0145] The aerosol-generating material may include an aerosol-generating film, or may be in the form of an aerosol-generating film. The aerosol-generating film may contain a binder such as a gelling agent and an aerosol-forming agent. Optionally, a delivered substance and / or fillers may also be present. The aerosol-generating film may not contain substantially any plant material. In particular, in some embodiments, the aerosol-generating material is substantially tobacco-free.

[0146] The aerosol-generating film may have a thickness of approximately 0.015 mm to approximately 1 mm. For example, the thickness may be in the range of approximately 0.05 mm, 0.1 mm, or 0.15 mm to approximately 0.5 mm or 0.3 mm.

[0147] The aerosol-generating film may be continuous. For example, the film may include a continuous material sheet, or may be a continuous material sheet. The sheet may be in the form of packaging material, may be gathered to form a gathered sheet, or may be shredded to form a shredded sheet. The shredded sheet may include one or more strands or strips of the aerosol-generating material.

[0148] An aerosol-generating film can be formed by combining a binder such as a gelling agent with a solvent such as water, an aerosol-forming agent, and one or more other components such as one or more substances to be delivered to form a slurry, and then heating the slurry to volatilize at least a portion of the solvent to form an aerosol-generating film.

[0149] The slurry may be heated to remove at least about 60 wt%, 70 wt%, 80 wt%, 85 wt%, or 90 wt% of the solvent.

[0150] The aerosol-generating material may include an amorphous solid. In some embodiments, the aerosol-generating material includes an aerosol-generating film which is an amorphous solid. The aerosol-generating film may be a monolithic solid. The aerosol-generating film may be substantially non-fibrous. In some embodiments, the aerosol-generating film may be a dry gel. The aerosol-generating film is a solid material capable of holding some fluid, such as a liquid, within it.

[0151] The aerosol-generating film does not need to contain substantially any plant-based material. The aerosol-generating film does not need to contain substantially any tobacco.

[0152] The aerosolizable material may be present on a substrate. The substrate may be, for example, paper, cardboard, cardboard, reconstituted aerosolizable material, plastic material, ceramic material, composite material, glass, metal, or metal alloy, or may include these.

[0153] Aerosol modifiers are substances that can modify aerosols during use. Aerosol modifiers can modify aerosols to produce physiological or sensory effects on the human body. Examples of aerosol modifiers include flavoring agents and sensory agents. Sensory agents create stimulating sensations that can be perceived through sensations such as coldness or sourness.

[0154] 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).

[0155] 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).

[0156] Therefore, a king-size super-slim article, for example, has a length of approximately 83 mm and a circumference of approximately 17 mm.

[0157] Each form can be manufactured using mouthpieces of different lengths. The mouthpiece lengths are approximately 10mm to 50mm, for example, 15mm to 35mm. The tip paper connects the mouthpiece to the aerosol-generating material, such that the tip paper covers the mouthpiece and overlaps the aerosol-generating material in the form of a rod of the aerosol-generating material, connecting the mouthpiece to the rod. The tip paper is usually longer than the mouthpiece, for example, 3 to 15mm or 3 to 12mm longer.
