Description

Technical Field

[0001] This invention relates to components, articles, and aerosol supply systems for use in aerosol supply systems. Background Technology

[0002] Some tobacco industry products generate aerosols that are inhaled by the user during use. For example, tobacco heating devices heat an aerosol generating substrate (such as tobacco) to form an aerosol by heating rather than burning the substrate. In other aerosol delivery systems, the aerosol generating substrate is burned to form an aerosol. Such tobacco industry products typically include a mouthpiece through which the aerosol reaches the user's mouth. Summary of the Invention

Attached Figure Description

[0053] Embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, wherein: Figure 1A It is a side cross-sectional view of an article comprising an assembly having sections formed of aggregated sheet material arranged at the mouth end of the article; Figure 1B It is by Figure 1A A cross-sectional end view of the section formed by the aggregated sheet material along line X-X'; Figure 1C It is formed Figure 1B A side view of the section of sheet material; and Figure 2 It is a side cross-sectional view of an article comprising an assembly having a second section comprising aggregated sheet material and an aerosol modifier release assembly. Detailed Implementation

[0054] According to this disclosure, "aerosol supply system" includes both combustible aerosol supply system and non-combustible aerosol supply system.

[0055] According to this disclosure, a "combustible" aerosol supply system is an aerosol supply system in which the aerosol generating material is burned or ignited during use to facilitate the delivery of at least one substance to a user.

[0056] In some implementations, the delivery system is a combustible aerosol supply system, such as a system selected from the group consisting of cigarettes, cigarettes, and cigars.

[0057] In some embodiments, this disclosure relates to a component for use in a combustible aerosol supply system, such as a filter, filter rod, filter segment, tobacco stick, small stopper (spill, spill), aerosol modifier release component (such as capsule, thread or bead), or paper (such as forming paper, tipping paper or cigarette paper).

[0058] Products (such as rod-shaped products) are typically named according to their length: “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), “extra large” (typically in the range of 75-91 mm, e.g., about 79 mm to about 88 mm), “long” or “extra large” (typically in the range of 91-105 mm, e.g., about 94 mm to about 101 mm), and “extra long” (typically in the range of about 110 mm to about 121 mm).

[0059] They are also named according to the product circumference: "regular" (about 23-25 ​​mm), "wide" (greater than 25 mm), "fine" (about 22-23 mm), "semi-fine" (about 19-22 mm), "extra-fine" (about 16-19 mm), and "micro" (less than about 16 mm).

[0060] Therefore, extra-large and ultra-fine products will have, for example, a length of about 83 mm and a circumference of about 17 mm.

[0061] Each form can be produced using nozzles of varying lengths. Nozzle lengths can range from approximately 14 mm to 27 mm. A tipping paper connects the nozzle to the aerosol-generating material and typically has a greater length than the nozzle, such as 3 mm to 10 mm, such that the tipping paper covers the nozzle and overlaps with the aerosol-generating material (e.g., in the form of a rod of matrix material) to connect the nozzle to the rod.

[0062] The articles described herein, as well as their aerosol-generating materials and nozzles, can be made in, but are not limited to, any of the above-described forms.

[0063] The terms “upstream” and “downstream” as used in this article are relative terms defined relative to the direction in which the mainstream aerosol is drawn through the product or device during use.

[0064] As used herein, the term "tobacco material" means any material that includes tobacco or its derivatives or substitutes. The term "tobacco material" can include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Tobacco material can include one or more of ground tobacco, tobacco fiber, shredded tobacco, extruded tobacco, tobacco stems, tobacco flakes (tobacco lamina), reconstituted tobacco, and / or tobacco extracts.

[0065] In the accompanying drawings described herein, the same reference numerals are used to indicate equivalent features, articles, or components.

[0066] Figure 1A It is a side cross-sectional view of an article comprising an assembly having sections formed of aggregated sheet material arranged at the mouth end of the article.

[0067] Article 1 includes a cylindrical rod of aerosol-generating material 3 (in this example, tobacco material) and a downstream portion of the rod connected to the aerosol-generating material 3, referred to in this example as a nozzle 2, such that the downstream portion is downstream of the aerosol-generating material. The aerosol-generating material 3 provides aerosol when heated, for example, within a non-flammable aerosol supply device. In other embodiments, article 1 may include its own heat source, thereby forming an aerosol supply system without requiring a separate aerosol supply device.

[0068] In this example, the component (in this case, nozzle 2) includes: a first segment 4 disposed at the nozzle end of the article; and a second segment 6 disposed upstream of the first segment 4, between the first segment 4 and the rod of the aerosol generating material 3. The first segment 4 includes a material body formed of aggregated sheet material 4A. The sheet material 4A can be folded to form the first segment 4. The first segment 4 can be formed from a continuous web of sheet material. In this example, the sheet material 4A is aggregated to form the first segment 4 in a manner similar to a "crepe filter". The aggregated sheet material 4A defines a plurality of channels extending longitudinally through the first segment 4.

[0069] The first segment 4 can be manufactured using the CU-20 filter manufacturing machine manufactured by Decouflé™. However, those skilled in the art will understand that other machines can be used to manufacture the first segment 4.

[0070] The main body of the material is surrounded by the first forming paper 7. For example... Figure 1B As shown, the inner surface of the forming paper 7 defines the inner diameter 'd' of the first section 4.

[0071] In some embodiments, the first forming paper 7 has a basis weight between 60 gsm and 120 gsm, for example, between 70 gsm and 80 gsm. It has been found that such a basis weight yields a suitable stiffness level for the nozzle. In some embodiments, the basis weight of the first forming paper 7 can be at least 60 gsm, at least 70 gsm, at least 80 gsm, at least 90 gsm, or at least 100 gsm. In other embodiments, the first forming paper 7 can have a basis weight between 50 gsm and 90 gsm, and less than 0.5 g / cm³. 3 The density.

[0072] The first forming paper 7 can be, for example, a permeable wrapping material having a basis weight of 50 gsm to 90 gsm and less than 0.5 g / cm³. 3 The density. The first section 4 can have a hardness greater than 90%. The first forming paper 7 can, for example, have a permeability greater than 100 Coresta units or greater than 500 Coresta units.

[0073] In some embodiments, the first forming paper 7 has a thickness between 30 μm and 60 μm, or between 35 μm and 45 μm. However, it should be understood that the thickness of the first forming paper 7 can be higher to increase the rigidity of the nozzle. In some embodiments, for example, the thickness of the first forming paper 7 can be at least 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm. In some embodiments, the thickness of the first forming paper 7 is in the range of 40 μm to 125 μm, or in the range of 50 μm to 100 μm.

[0074] The width of the sheet material 4A gathered to form the first segment 4 can be an unfolded width between 5 and 30 times the inner diameter of the first segment 4. The unfolded width refers to the width of the sheet material 4A before any pleating is applied or the sheet material 4A is gathered to form the material body as described above. The unfolded width of the sheet material already formed as the material body can be determined by stretching the sheet material 4A to a point where any width reduction caused by pleating is substantially reversed.

[0075] Sheet material 4A may be a fibrous sheet material. In this example, sheet material 4A includes cellulose. In this example, sheet material 4A is paper. In some embodiments, sheet material 4A may be a combustible sheet material. In some embodiments, sheet material 4A may be a nonwoven material.

[0076] In some embodiments, the continuous web of sheet material 4A has an unfolded width of at least 35 mm, at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, or at least 120 mm.

[0077] In some embodiments, the continuous web of sheet material 4A has an unfolded width of up to 230 mm, up to 220 mm, up to 200 mm, up to 180 mm, up to 150 mm, up to 140 mm, up to 130 mm, up to 120 mm, or up to 100 mm.

[0078] In some embodiments, the sheet material 4A has an unfolded width in the range of 38 mm to 230 mm, for example 60 mm to 160 mm, for example 70 mm to 150 mm, or 80 mm to 120 mm. When the basis weight of the sheet material 4A is oriented towards the higher end of the range described below, the unfolded width of the sheet material 4A oriented towards the lower end of the range may be particularly suitable.

[0079] In this example, the first segment 4 has an inner diameter of approximately 7.6 mm, and the assembled sheet material 4A has an unfolded width of approximately 114 mm.

[0080] In one example, the sheet material 4A may have a basis weight in the range of 20 gsm to 120 gsm, for example 30 gsm to 85 gsm, 30 gsm to 65 gsm, 34 gsm to 60 gsm or 40 gsm to 50 gsm.

[0081] In some embodiments, the sheet material 4A has a basis weight of at least 15 gsm, at least 20 gsm, at least 25 gsm, or at least 30 gsm.

[0082] In some embodiments, the sheet material 4A has a basis weight of 120 gsm or less, 100 gsm or less, 90 gsm or less, 80 gsm or less, or 70 gsm or less.

[0083] For example, in terms of hardness and pressure drop, choosing a basis weight of sheet material 4A between approximately 70 gsm and approximately 120 gsm can be advantageous. Such sheet materials can have thicknesses between approximately 100 micrometers and approximately 160 micrometers. The density of sheet material 4A can be approximately 0.6 gsm / cm³. 3 and approximately 0.9 gms / cm 3 Between, for example, at approximately 0.65 gms / cm 3 and approximately 0.75 gms / cm3 between.

[0084] In this example, the sheet material 4A is pleated before being arranged into the first segment 4. For example, the sheet material 4A may pass through a pair of crimping rollers. In this example, the first segment 4 comprises a pleated sheet material 4A with a crimped pattern consisting of a series of substantially parallel ridges and grooves. The crimping makes it easier for the sheet material 4A to be assembled to form the first segment 4. In other examples, the sheet material 4A may not be crimped.

[0085] In this example, the material body comprises a pleated sheet material 4A with a pleated pattern comprising a series of substantially parallel ridges and grooves, and the average spacing between adjacent ridges is greater than about 0.3 mm. Additionally, in this example, the pleat amplitude is equal to or less than about 0.5 mm or less than about 0.4 mm. In some examples, the pleat amplitude of the sheet material forming the first segment is less than 0.7 mm, 0.6 mm, 0.5 mm, 0.4 mm, 0.3 mm, 0.2 mm, or 0.1 mm. In some examples, the pleat amplitude of the sheet material 4A forming the first segment 4 is at least 0.05 mm. For example, the pleat amplitude of the sheet material 4 forming the first segment can be between about 0.1 mm and about 0.5 mm, or between about 0.15 mm and about 0.4 mm.

[0086] The wrinkle amplitude (also known as the "wrinkle factor") refers to the depth of the grooves formed by wrinkles in the sheet material that forms the main body. In other words, when viewed from the first side of the sheet material, the wrinkles create multiple peaks and valleys within the sheet material, such as... Figure 1C As shown, the fold amplitude 'A' is the valley depth measured from its peak. The folds can form a zigzag shape or another shape. In some embodiments, adjacent grooves of the folded sheet material 4A are spaced apart by a distance, or have a pitch 'P' in the range of 0.3 mm to 2 mm, and preferably in the range of 0.4 mm to 1 mm. In some embodiments, adjacent grooves of the folded sheet material 4A are spaced apart by a distance of at least 0.4 mm or at least 0.5 mm, 0.6 mm, 0.7 mm, or 0.8 mm. In some embodiments, adjacent grooves of the folded sheet material 4A are spaced apart by a distance of at most 1.5 mm, and preferably at most 1.4 mm, 1.3 mm, 1.2 mm, 1.1 mm, or 1.0 mm. Adjacent grooves of the folded sheet material 4A can, for example, be spaced apart by about 0.3 mm to about 1.2 mm, or by about 0.4 mm to about 1 mm.

[0087] Each of the multiple longitudinally extending channels in the first section 4 can have a diameter of less than 3 mm.2 Optionally less than 2 mm 2 or less than 1 mm 2 The cross-sectional area. One or more of the multiple channels can each have a cross-sectional area greater than 0.5 mm. 2 Optional location greater than 1mm 2 or greater than 1.5 mm 2 The cross-sectional area. Such channel dimensions allow the first section 4 to exhibit relatively low pressure drop or suction resistance along its length, while the visual appearance of the first section is not significantly different from that of a standard cellulose acetate filter.

[0088] The first section 4 may have a pressure drop that extends through the length of the section, which is less than 30 mmH2O, or less than 20 mmH2O, for example less than about 18 mmH2O, or less than 15 mmH2O, or less than 10 mmH2O.

[0089] In some examples, the pressure drop across the length of the first segment 4 is at least 5 mmH2O, or at least 7 mmH2O, or at least 8 mmH2O, or at least 10 mmH2O.

[0090] In some examples, the pressure drop per mm along the length of the first segment 4 is at least 1.1 mmH2O / mm, or at least 1.5 mmH2O / mm, or at least 2 mmH2O / mm.

[0091] The pressure drop across the length of the first segment 4 can be less than 0.25 mmH2O per mm of the first segment length, or less than 0.20 mmH2O per mm of the first segment length, or less than 0.15 mmH2O per mm of the first segment length. The pressure drop across the length of the first segment can be between 0.05 mmH2O per mm of the first segment length and 0.50 mmH2O per mm of the first segment length, or between 0.05 mmH2O per mm of the first segment length and 0.25 mmH2O per mm of the first segment length.

[0092] The pressure drop along the length of the first section, as well as other pressure drops and suction resistance values ​​defined herein, were determined according to the ISO standard method (ISO 6565:2015). Pressure drop refers to "closure pressure drop," where any ventilated area of ​​the measured product or body is closed during the measurement.

[0093] In some examples, the first segment 4 forms the nozzle of the article. In such examples, the difference between the pressure drop along the length of the article and the pressure drop along the length of the article that does not have the first segment 4 at the nozzle but is otherwise identical can be greater than the pressure drop along the length of the first segment 4. For example, the first segment 4 may have a pressure drop of 5 mmH2O along its length, but when added to the nozzle of the article, it can increase the pressure drop along the length of the article by more than 5 mmH2O. This is presumably due to the effect of the first segment 4 on the airflow path upstream of the first segment 4.

[0094] In some embodiments, the nozzle 2 has a hardness in the first section 4 ranging from about 70% to 95% or from about 75% to 85%. The hardness of the nozzle 2 in the first section can be at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, or at least 83%. The hardness of the nozzle in the first section can be about 90%.

[0095] The hardness of nozzle 2 can be measured using the following method. When referring to the hardness of a section in this document, hardness means the hardness determined by the following measurement procedure. Any suitable device (such as the Borgwaldt H10 hardness tester) can be used to perform the measurement.

[0096] Hardness is defined as the ratio between the height h0 of the body and its height h1 under a defined load, expressed as a percentage of h0. Hardness can be expressed as: Hardness = (h1 / h0) × 100 For a single body or a body contained in a multi-segment bar, hardness measurement is performed at the longitudinal center point of the body or the multi-segment bar.

[0097] A load bar is used to apply a defined load to the body. The length of the load bar should be significantly greater than the length of the test specimen. Before hardness measurement, the test specimen should be conditioned for at least 48 hours according to ISO 3402:2023 and maintained under environmental conditions according to ISO 3402:2023 during the measurement.

[0098] To perform hardness measurements, the sample was placed in a hardness tester H10, a 2 g preload was applied, and the initial height h0 of the sample under the 2 g preload was recorded after 1 s. The preload was then removed, and a load bar bearing a 150 g load was lowered onto the sample at a rate of 0.6 mm / s. After 5 s, the height h1 of the sample under the 150 g load was measured.

[0099] The hardness of the nozzle was determined as the average hardness of at least 20 nozzles measured according to the scheme.

[0100] Alternatively, the above method can be used to carefully cut the article to remove the first segment 4 surrounded by the first forming paper 7, and then measure the hardness of the first segment 4 (hereinafter collectively referred to as the "component" for the purpose of hardness measurement). The hardness of the component can be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%. Preferably, the hardness of the component is between about 80% and about 95%.

[0101] In some examples, the first segment 4 has a length of at least 4 mm, such as at least 5 mm, at least 6 mm, at least 7 mm, or at least 8 mm. In some examples, the first segment has a length of less than 10 mm.

[0102] In this example, the second segment 6 is positioned immediately downstream of the rod containing the aerosol-generating material 3. In other examples, additional components may exist between the second segment 6 and the rod containing the aerosol-generating material 3.

[0103] The second segment 6 is also formed of aggregated sheet material in a similar manner to that described in relation to the first segment 4, and the aggregated sheet material forming the second segment 6 is referred to as the second aggregated sheet material. The total pressure drop along the length of the second segment 6 may be greater than the total pressure drop along the length of the first segment 4. Alternatively or additionally, the pressure drop per mm along the length of the second segment 6 may be greater than the pressure drop per mm along the length of the first segment 4.

[0104] The second aggregate sheet material may have the same composition as the first aggregate sheet material 4A, i.e., the second aggregate sheet material may be a fibrous sheet material and / or formed from cellulose material. In this example, the second aggregate sheet material is paper. In some examples, the second aggregate sheet material may be a combustible sheet material and / or a nonwoven material.

[0105] The second section is formed from a second aggregate of sheet material (not shown), the second aggregate of sheet material having an unfolded width greater than the unfolded width of the sheet material forming the first section 4.

[0106] The second section 6 may have an outer perimeter defined by the inner surface of the second forming paper 8, which defines the cross-sectional area of ​​the second section 6, and the sheet material aggregated within the outer perimeter per mm 3The average density is approximately constant over the cross-sectional area of ​​the second segment 6. This can be achieved by using pleats to allow the relatively constant aggregation of the second aggregated sheet material to form the second segment 6.

[0107] The second aggregate of sheet material defines multiple longitudinally extending channels through the second segment 6. In some examples, the cross-sectional area of ​​at least one of the channels through the second segment 6 is less than 1 mm². 2 In some examples, the average cross-sectional area of ​​multiple channels through the second segment 6 is less than 1 mm². 2 In some other examples, the cross-sectional area of ​​each channel in the second segment 6 is less than 3 mm². 2 Less than 2 mm 2 or less than 1 mm 2 The second aggregate of sheet material may be wrinkled in a manner similar to that described in relation to the first sheet material 4A. In this example, the second aggregate of sheet material is wrinkled before being arranged into the second segment 6. In other examples, the second aggregate of sheet material may not be wrinkled.

[0108] In some examples, the level of wrinkling applied to the sheet material in the second aggregate can make the width of the sheet material aggregated in the second segment 6 greater than the amount of sheet material aggregated in the first segment 4. Increasing the amount of sheet material in the second segment 6 increases the surface area of ​​the sheet material in contact with the aerosol passing through the second segment 6. This results in a pressure drop along the length of the second segment 6 that is greater than that along the length of the first segment 4. This arrangement of relative pressure drops can cause the second segment 6, located upstream of the first segment 4, to have a higher filtration efficiency than the first segment 4. Advantageously, the relatively lower contribution of the first segment 4 to aerosol filtration compared to the second segment 6 can reduce visible staining of the first segment 4 during use, and the appearance of the nozzle 2 can be more acceptable to the user.

[0109] The unfolded width of the first aggregated sheet material can be 10 mm to 100 mm smaller or 10 mm to 20 mm smaller than the unfolded width of the second aggregated sheet material. The unfolded width of the first aggregated sheet material can be 8% to 50% smaller than the width of the second aggregated sheet material. The unfolded width of the first aggregated sheet material can be 8% to 20% smaller than the width of the second aggregated sheet material.

[0110] The first segment 4 may be disposed at the distal upstream end of articles 1, 1', opposite the nozzle end 2b or downstream end 2b of articles 1, 1', as an alternative to or supplement to the first segment disposed at the nozzle end 2b. In these cases, the first segment 4 may help hold the aerosol-generating material 3 in place. In these cases, when the first segment 4 is disposed at the upstream end rather than the downstream end, the second segment 6 may be omitted, or included as a nozzle end assembly of articles 1, 1'. The first segment 4 may provide articles 1, 1' with a new distal appearance. The length of this assembly may be between 4 mm and 8 mm, or between 5 mm and 7 mm, when disposed at the distal end. The first segment 4 may include an aerosol-forming agent material as defined herein, such as glycerin. Alternatively or additionally, the first segment 4 may include an active substance as defined herein, such as nicotine.

[0111] In some examples, at least one of the first segment 4 or the second segment 6 may be processed to alter its visual appearance compared to the other of the first segment 4 or the second segment 6. For example, the sheet material forming the segment may be bleached, dyed, or otherwise altered in appearance. This can facilitate the differentiation of the segments using sensors such as light sensors during high-speed manufacturing.

[0112] In some examples, the pressure drop along the length of the material body forming the second segment 6 is at least 10 mmH2O, at least 15 mmH2O, or at least 20 mmH2O, at least 30 mmH2O, or at least 40 mmH2O.

[0113] In some examples, the pressure drop along the length of the material body forming the second segment 6 is less than 150 mmH2O, less than 100 mmH2O, less than 80 mmH2O, less than 60 mmH2O, less than 50 mmH2O, less than 45 mmH2O, less than 42 mmH2O, or less than 40 mmH2O.

[0114] In some examples, the pressure drop along the length of the material body forming the second segment 6 is about 20 mmH2O, 22 mmH2O, or 25 mmH2O. In some examples, the pressure drop along the length of the material body forming the second segment 6 is about 30 mmH2O, 32 mmH2O, or 35 mmH2O.

[0115] In some examples, the pressure drop along the length of the material body forming the second segment 6 is in the range of 10 mmH2O to 40 mmH2O, or in the range of 15 mmH2O to 30 mmH2O.

[0116] In some examples, the pressure drop through the length of the material body forming the second segment 6 is at least 1.0 mmH2O per mm of axial length of the material body forming the second segment 6. In some embodiments, the pressure drop through the length of the material body forming the second segment 6 is at least 1.2 mmH2O, 1.5 mmH2O, or 1.8 mmH2O per mm of axial length of the material body.

[0117] In some embodiments, the pressure drop across the length of the material body forming the second segment 6 is less than 10 mmH2O, 8 mmH2O, 5 mmH2O, 3.0 mmH2O, 2.8 mmH2O, or 2.6 mmH2O per mm of axial length of the material body forming the second segment 6. In some embodiments, the pressure drop across the length of the material body forming the second segment 6 is less than 2.5 mmH2O, 2.4 mmH2O, or 2.3 mmH2O per mm of axial length of the material body forming the second segment 6.

[0118] In this example, the material body forming the second segment 6 comprises a sheet material with a pleated pattern, the pleating pattern including a series of substantially parallel ridges and grooves. In this example, the pleat width is between approximately 0.4 mm and 0.7 mm. For example, the pleat width of the sheet material can be approximately 0.4 mm, 0.5 mm, 0.6 mm, or 0.7 mm.

[0119] In some embodiments, adjacent grooves of the pleated sheet material are spaced apart by a distance of at least 0.4 mm, or at least 0.5 mm, 0.6 mm, 0.7 mm, or 0.8 mm. In some embodiments, adjacent grooves of the pleated sheet material 10 are spaced apart by a distance of at most 1.5 mm, and preferably at most 1.4 mm, 1.3 mm, 1.2 mm, 1.1 mm, or 1.0 mm. For example, the sheet material may have pleats, wherein the pleat amplitude is less than 1 mm, and the spacing between peaks (or valleys) is at least 300 μm, at least 400 μm, or at least 500 μm.

[0120] In some embodiments, the continuous web of the sheet material has an unfolded width of at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 110 mm, or at least 120 mm.

[0121] In some embodiments, the continuous web of the sheet material has an unfolded width of up to 300 mm, up to 280 mm, up to 260 mm, up to 240 mm, up to 230 mm, up to 220 mm, up to 210 mm, up to 200 mm, or up to 190 mm.

[0122] In some examples, the unfolded width of the first aggregate of sheet material 4A may be 8% to 50% or 8% to 20% smaller than the unfolded width of the second aggregate of sheet material. For example, the unfolded width of the second sheet material may be about 170 mm, and the unfolded width of the first sheet material 4A may be about 100 mm. In this example, the unfolded width of the second sheet material is suitably between about 120 mm and about 180 mm, or between about 124 mm and about 143 mm. In this example, the unfolded width of the second aggregate of sheet material may be about 125 mm.

[0123] The second section 6 is surrounded by a second forming paper 8. In some embodiments, the second forming paper 8 has a basis weight between 20 gsm and 120 gsm, for example between 40 gsm and 100 gsm, or between 50 gsm and 80 gsm. The second forming paper 8 may be, for example, a permeable wrapping material having a basis weight of 50 gsm to 90 gsm and less than 0.5 g / cm³. 3 The density. The second-formed paper 8 may, for example, have a permeability greater than 100 Coresta units or greater than 500 Coresta units.

[0124] In one example, the sheet material of the second aggregate may have a basis weight in the range of 20 gsm to 45 gsm, for example, 25 gsm to 35 gsm. In some embodiments, the sheet material has a basis weight of at least 20 gsm, at least 30 gsm, or at least 40 gsm. In some embodiments, the sheet material may have a basis weight of up to 120 gsm.

[0125] In some embodiments, the sheet material has a basis weight of 50 gsm or less, 40 gsm or less, or 30 gsm or less. Preferably, the sheet material has a basis weight of 45 gsm or less.

[0126] In some examples, the second segment 6 has a length of at least 10 mm. For example, the second segment 6 may have a length of at least 12 mm, at least 15 mm, at least 18 mm, or at least 20 mm.

[0127] The pressure drop or differential pressure (also known as suction resistance) across the length of the mouthpiece 2 is less than about 180 mmH2O. It has been found that such a pressure drop allows sufficient aerosol (including desired compounds, such as flavoring compounds) to pass through the mouthpiece 2 and reach the consumer. In some embodiments, the pressure drop across the length of the mouthpiece is less than about 150 mmH2O, about 130 mmH2O, about 100 mmH2O, or about 50 mmH2O. In some embodiments, the pressure drop across the length of the mouthpiece 2 is at least 20 mmH2O, or 30 mmH2O, or 40 mmH2O. Preferably, the pressure drop across the length of the mouthpiece 2 is between about 40 mmH2O and 150 mmH2O.

[0128] In this example, ventilation is provided into the second section 6. In this example, ventilation is provided by a vent 12, which is formed through the tipping paper 5, the second forming paper 8, and the third forming paper 9 to provide ventilation into the second section 6.

[0129] In this example, the first segment 4 and the second segment 6 are surrounded by a third forming paper 9. The third forming paper 9 can be adhered to the components of the article by an adhesive applied to the overlapping seam extending longitudinally along the second forming paper. Alternatively or additionally, the third forming paper 9 can be directly adhered to the underlying component using an adhesive. In both cases, the adhesive can be selected as a water-soluble adhesive to aid in the degradation of the component. Additionally or alternatively, the third forming paper 9 itself can be formed of paper or other materials with improved biodegradability (e.g., improved dispersibility when exposed to water).

[0130] In some embodiments, the third forming paper 9 has a basis weight of less than 120 gsm. In some embodiments, the third forming paper 9 has a basis weight between about 70 gsm and about 80 gsm. However, it should be appreciated that the basis weight of the third forming paper 9 can be higher to increase the stiffness of the nozzle. For example, the basis weight of the third forming paper 9 can be between about 60 gsm and 120 gsm. In some embodiments, the basis weight of the third forming paper 9 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.

[0131] In some embodiments, the third forming paper 9 has a thickness between 30 μm and 60 μm, or between 35 μm and 45 μm. However, it should be understood that the thickness of the third forming paper 9 can be higher to increase the stiffness of the nozzle. In some embodiments, for example, the thickness of the third forming paper 9 can be at least 40 μm, at least 50 μm, at least 60 μm, at least 70 μm, at least 80 μm, at least 90 μm, or at least 100 μm. In some embodiments, the thickness of the third forming paper 9 is in the range of 40 μm to 120 μm, or in the range of 50 μm to 100 μm.

[0132] In some embodiments, the third forming paper 9 is a non-porous forming paper with a permeability of less than 100 coresta units, for example, less than 50 coresta units. However, in alternative embodiments, the third forming paper 9 can be a porous forming paper, for example, with a permeability of greater than 200 coresta units.

[0133] The first segment 4, the second segment 6, and the mouthpiece 2 may each be referred to as an assembly. Such assemblies as described herein are particularly suitable for use as mouthpieces in articles of manufacture. In some examples, the mouthpiece may include additional segments besides those described herein.

[0134] Biodegradability can be measured according to the procedures specified in ISO 14855-2:2018. When exposed to fresh or seawater, the components described herein can achieve greater than 50% biodegradation within 30 days.

[0135] In some examples, the sheet material 4A forming the first segment 4 may include a coating applied to the sheet material 4A prior to or during the process of forming the material body. In some examples, the coating on the sheet material 4A may include a polymer, resin, adhesive, or polysaccharide. In some examples, the coating may increase the stiffness of the first segment 4, for example by hardening the sheet material 4A, or by bonding adjacent folds in the aggregated sheet material 4A to each other to increase the rigidity of the aggregated sheet material body.

[0136] In some examples, substantially the entire surface area of ​​the sheet material 4A may be covered by a coating. In other examples, the coating may be applied to the surface area of ​​the sheet material 4A in a varying pattern. For example, the coating may be applied in a dot matrix pattern or arranged as lines across or along the surface of the sheet material 4A. In some examples, the coating may be arranged such that at least a portion of the sheet material 4A remains uncoated.

[0137] When sheet material 4A is formed into a material body, the portions of the sheet material can come into contact with each other, forming contact areas. In some examples, a coating on the surface of sheet material 4A can strengthen or permanently bond the contact areas between the portions of the sheet material together, for example, due to the bond formed between the coated portions of the sheet material at the contact areas. Alternatively, or in addition to strengthening the contact areas between the portions of the sheet material, the coating can also provide additional rigidity to the entire surface of sheet material 4A or the coated area of ​​the sheet material, so that the body formed from the coated sheet material can have increased hardness.

[0138] Preferably, the aerosol generating material or matrix is ​​formed from tobacco material as described herein, which includes tobacco components.

[0139] In this example, the aerosol generating material 3 is enclosed in a wrapper 10. The wrapper 10 can be, for example, a paper or paper foil wrapper. In this example, the wrapper 10 is permeable cigarette paper. In other examples, the wrapper 10 can be substantially impermeable to air, particularly where the article 1 is intended for use with a non-flammable aerosol supply system, as further described below.

[0140] Preferably, the aerosol generating material 3 is provided as a cylindrical rod of aerosol generating material. Regardless of the form of the aerosol generating material, it preferably has a length of about 10 mm to about 100 mm. In some embodiments, the length of the aerosol generating material is preferably in the range of about 25 mm to 50 mm, more preferably in the range of about 30 mm to 45 mm, and even more preferably about 30 mm to 40 mm.

[0141] The tobacco material can be provided in the form of cut rag tobacco. The cut rag tobacco can have a cut width of at least 15 cuts per inch (approximately 5.9 cuts / cm, equivalent to approximately 1.7 mm). Preferably, the cut rag tobacco has a cut width of at least 18 cuts per inch (approximately 7.1 cuts / cm, equivalent to approximately 1.4 mm), more preferably at least 20 cuts per inch (approximately 7.9 cuts / cm, equivalent to approximately 1.27 mm). In one example, the cut rag tobacco has a cut width of 22 cuts per inch (approximately 8.7 cuts / cm, equivalent to approximately 1.15 mm). Preferably, the cut rag tobacco has a cut width of 40 cuts per inch or less (approximately 15.7 cuts / cm, equivalent to approximately 0.64 mm). It has been found that shred widths between 0.5 mm and 2.0 mm, for example between 0.6 mm and 1.5 mm, or between 0.6 mm and 1.7 mm, result in preferred properties for the tobacco material, particularly when heated, in terms of surface area to volume ratio and the total density and pressure drop of the aerosol-generating material 3. Shredded tobacco can be formed from mixtures of various forms of tobacco material, such as one or more mixtures of paper-reconstituted tobacco, tobacco leaves, extruded tobacco, and belt-cast tobacco. Preferably, the tobacco material comprises paper-reconstituted tobacco or a mixture of paper-reconstituted tobacco and tobacco leaves.

[0142] The tobacco materials described herein may include filler components. Filler components are generally non-tobacco components, i.e., components that do not contain ingredients derived from tobacco. Filler components may be non-tobacco fibers, such as wood fibers or pulp or wheat fibers. Filler components may also be inorganic materials, such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may also be non-tobacco casting materials or non-tobacco extrusion materials. Filler components may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1% to 10% by weight of the composition. In some embodiments, no filler components are present.

[0143] In the tobacco materials described herein, the tobacco materials may include aerosol-forming materials. In this context, "aerosol-forming material" is an agent that promotes aerosol generation. Aerosol-forming materials can promote aerosol generation by facilitating the initial evaporation and / or condensation of gases into inhalable solid and / or liquid aerosols. In some embodiments, aerosol-forming materials can improve the delivery of flavorings to the aerosol-generating material. Generally, any suitable aerosol-forming material or agent can be included in the aerosol-generating material of the present invention, including those described herein. Other suitable aerosol forming agent materials include, but are not limited to: polyols, such as sorbitol, glycerol, and glycols, such as propylene glycol or triethylene glycol; non-polyols, such as monohydric alcohols, high-boiling hydrocarbons, acids, such as lactic acid, glycerol derivatives, esters, such as glyceryl diacetate, glyceryl triacetate, triethylene glycol diacetate, triethyl citrate, or myristate esters including ethyl myristate and isopropyl myristate, and aliphatic carboxylic acid esters, such as methyl stearate, dimethyl dodecanoate, and dimethyl tetradecanoate. In some embodiments, the aerosol forming agent material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10% to 20% by weight of the tobacco material, for example, 13% to 16% by weight of the composition, or about 14% or 15% by weight of the composition. Propylene glycol (if present) may be present in an amount of 0.1% to 0.3% by weight of the composition.

[0144] Aerosol forming materials may be included in any component of the tobacco material (e.g., any tobacco component) and / or in the filler component (if present). Alternatively or additionally, aerosol forming materials may also be added to the tobacco material alone. In either case, the total amount of aerosol forming material in the tobacco material may be as defined herein.

[0145] In some examples, tobacco material may be contained in between 10% and 90% of the tobacco leaf by weight, wherein aerosol forming agent material is provided at a maximum of about 10% by weight of the tobacco leaf. To achieve a total level of aerosol forming agent material between 10% and 20% by weight of the tobacco material, it has been advantageously found that this can be added at a higher weight percentage to another component of the tobacco material, such as reconstituted tobacco material.

[0146] The tobacco material described herein contains nicotine. The nicotine content is 0.5% to 1.75% by weight of the tobacco material, and may be, for example, 0.8% to 1.5% by weight of the tobacco material. Alternatively or additionally, the tobacco material comprises between 10% and 90% by weight of tobacco leaves having a nicotine content greater than 1.5% by weight of the tobacco leaves. It has been advantageously found that using tobacco leaves with a nicotine content higher than 1.5% in combination with lower nicotine-based materials (such as paper-processed reconstituted tobacco) provides tobacco material with appropriate nicotine levels but better sensory performance than using paper-processed reconstituted tobacco alone. The tobacco leaves (e.g., shredded tobacco) may have a nicotine content, for example, between 1.5% and 5% by weight of the tobacco leaves.

[0147] The tobacco material described herein may contain aerosol modifiers, such as any flavoring agents described herein. In one embodiment, the tobacco material contains menthol, thereby forming a menthol-containing article. The tobacco material may include 3 mg to 20 mg of menthol, preferably between 5 mg and 18 mg, and more preferably between 8 mg and 16 mg of menthol. The tobacco material may contain between 2% and 8% by weight of menthol, preferably between 3% and 7% by weight, and more preferably between 4% and 5.5% by weight of menthol. In one embodiment, the tobacco material includes 4.7% by weight of menthol. This high level of menthol loading can be achieved using a high percentage of reconstituted tobacco material, such as more than 50% by weight of tobacco material. Alternatively or additionally, for example, using a material larger than about 500 mm 3 Or appropriately larger than about 1000 mm 3 In the case of aerosol-generating materials (such as tobacco materials), using high-volume aerosol-generating materials (such as tobacco materials) can increase the achievable menthol loading level.

[0148] In the compositions described herein, amounts are given as % by weight, which, for the avoidance of doubt, refers to a dry weight basis unless specifically stated otherwise. Therefore, any water that may be present in the tobacco material or any of its components can be completely ignored for the purpose of determining % by weight. The water content of the tobacco material described herein can vary and can be, for example, from 5% to 15% by weight. The water content of the tobacco material described herein can vary depending on, for example, the temperature, pressure, and humidity conditions used to maintain the composition. The water content can be determined by Karl-Fisher analysis known to those skilled in the art. On the other hand, for the avoidance of doubt, even when the aerosol forming agent material is a liquid component (such as glycerol or propylene glycol), any component other than water is included in the weight of the tobacco material. However, when the aerosol forming agent material is provided in the tobacco component of the tobacco material or in the filler component of the tobacco material (if present), instead of being included in the weight of the tobacco component or filler component alone, the aerosol forming agent material is not included in the weight of the tobacco component or filler component, but is included in the weight of “aerosol forming agent material” as defined herein. All other components present in the tobacco component are included in the weight of the tobacco component, even those not of tobacco origin (e.g., non-tobacco fibers in the case of papermaking reconstituted tobacco).

[0149] In some embodiments, the tobacco material includes a tobacco component as defined herein and an aerosol forming agent material as defined herein. In some embodiments, the tobacco material is substantially composed of a tobacco component as defined herein and an aerosol forming agent material as defined herein. In some embodiments, the tobacco material is composed of a tobacco component as defined herein and an aerosol forming agent material as defined herein.

[0150] Paper-processed reconstituted tobacco may be present in the tobacco component of the tobacco material described herein at an amount of 10% to 100% by weight of the tobacco component. In some embodiments, paper-processed reconstituted tobacco is present at an amount of 10% to 80% or 20% to 70% by weight of the tobacco component. In another embodiment, the tobacco component consists essentially of, or is composed of, paper-processed reconstituted tobacco. In a preferred embodiment, tobacco leaves are present in the tobacco component of the tobacco material at an amount of at least 10% by weight of the tobacco component. For example, tobacco leaves may be present at an amount of at least 10% by weight of the tobacco component, while the remainder of the tobacco component comprises paper-processed reconstituted tobacco, ribbon-cast reconstituted tobacco, or a combination of ribbon-cast reconstituted tobacco and another form of tobacco, such as tobacco pellets.

[0151] Paper-based reconstituted tobacco refers to tobacco material formed through a process in which tobacco raw material is extracted with a solvent to provide a soluble extract and a residue comprising fibrous material, and then the extract (usually after concentration and optionally after further processing) is reconstituted with the fibrous material from the residue (usually after refining the fibrous material and optionally with the addition of a portion of non-tobacco fibers) by depositing the extract onto the fibrous material. The reconstitution process is similar to that of papermaking.

[0152] Paper-processed reconstituted tobacco can be any type of paper-processed reconstituted tobacco known in the art. In a specific embodiment, paper-processed reconstituted tobacco is made from raw materials comprising one or more of tobacco sticks, stems, and whole leaves. In another embodiment, paper-processed reconstituted tobacco is made from raw materials consisting of tobacco sticks and / or whole leaves and stems. However, in other embodiments, waste, fine powder, and winnowing may be alternatively or additionally used in the raw materials.

[0153] Paper-based reconstituted tobacco used in the tobacco materials described herein can be prepared by methods known to those skilled in the art for preparing paper-based reconstituted tobacco.

[0154] In this example, article 1 has an outer perimeter of approximately 24.8 mm (i.e., the article is in a conventional form).

[0155] The outer perimeter of nozzle 2 is substantially the same as the outer perimeter of rod of aerosol generating material 3, resulting in a smooth transition between these components.

[0156] In some examples, the tipping paper 5 includes citrates, such as sodium citrate or potassium citrate. In such examples, the tipping paper 5 may have a citrate content of 2% or less, or 1% or less, by weight. Reducing the citrate content of the tipping paper 5 is believed to help reduce the scorching effect that may occur during use in non-flammable solvent supply systems.

[0157] In this example, the tipping paper 5 extends 5 mm over the rod of the aerosol-generating material 3, but it can alternatively extend 3 mm to 10 mm or more preferably 4 mm to 6 mm over the rod 3 to provide a strong attachment between the nozzle 2 and the rod 3. In some examples, the tipping paper 5 may have a basis weight of 40 gsm to 80 gsm, for example, between 50 gsm and 70 gsm, such as 58 gsm. These basis weight ranges have been found to result in tipping papers with acceptable tensile strength while having sufficient flexibility to wrap around the article 1 and adhere to the tipping paper itself along the longitudinal lap joint on the paper. In this example, once wrapped around the nozzle 2, the outer perimeter of the tipping paper 5 is approximately 24 mm.

[0158] In some examples, the articles 1, 1' described herein can be modified for use in or as a non-flammable aerosol supply system. The construction of one or more encapsulations, components of the aerosol-generating material, and / or nozzle components can be modified to produce articles particularly suitable for use in or as a non-flammable aerosol supply system. For example, a tubular portion, as described below, can be provided as a cooling section in an article intended for use in a non-flammable aerosol supply system. The encapsulation 10 surrounding the aerosol-generating material can suitably be substantially air-impermeable in the article for use in a non-flammable aerosol supply system. Those skilled in the art will also appreciate suitable modifications to the composition of the aerosol-generating material, such as the inclusion of an aerosol forming agent. The following paragraphs describe features of articles that can be particularly suitable for use in a non-flammable aerosol supply system.

[0159] The length of the nozzle can also be greater in articles used or as non-flammable aerosol supply systems. For example, the nozzle of a non-flammable aerosol supply system can have a length of about 30 mm to about 50 mm. Although not shown, a tubular portion can be provided downstream of the aerosol generating material, for example, between the rod of the aerosol generating material 3 and the second section 6. This tubular portion may be referred to herein as a "cooling element".

[0160] A tubular portion is located around the nozzle and defines an air gap within the nozzle, which acts as a cooling section. The air gap provides a chamber through which heated volatile components generated by the aerosol-generating material 3 flow. The tubular portion is hollow to provide a chamber for aerosol buildup, but remains rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and in-process use. The tubular portion provides physical displacement between the aerosol-generating material 3 and the second segment 6. This physical displacement provided by the tubular portion will provide a thermal gradient along the length of the tubular portion.

[0161] In some embodiments, the mouthpiece includes a diameter greater than 450 mm. 3 The cavity has an internal volume. It has been found that providing a cavity of at least this volume enables the formation of improved aerosols. Such a cavity size provides sufficient space within the nozzle to allow the heated volatile components to cool, thus allowing the aerosol-generating materials 3 to be exposed to temperatures higher than possible in other cases, as these could lead to excessively high aerosol temperatures. Suitably, the cavity is formed by a tubular portion, but in alternative arrangements, it can be formed within different portions of the nozzle. In some embodiments, the nozzle includes a cavity, for example formed within a tubular portion, having a diameter greater than 500 mm. 3 For example, greater than 550 mm 3 The internal volume allows for further aerosol reduction. In some embodiments, the internal cavity comprises approximately 550 mm...3 With approximately 850 mm 3 Between, or at approximately 600 mm 3 With approximately 800 mm 3 The volume between.

[0162] The tubular portion can be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile component entering the first upstream end of the tubular portion and the heated volatile component exiting the second downstream end of the tubular portion. In some embodiments, the tubular portion is configured to provide a temperature difference of at least 60 degrees Celsius, at least 80 degrees Celsius, or at least 100 degrees Celsius between the heated volatile component entering the first upstream end of the tubular portion and the heated volatile component exiting the second downstream end of the tubular portion.

[0163] In some examples, the tubular portion is formed of multiple layers of paper wound parallel to each other at butt joints to form a hollow tube. For example, a first and second paper layer may be disposed within a double-layered tube, although in other examples three, four, or more paper layers may be used to form a three-, four-, or more-layered tube. Other structures may also be used, such as spirally wound paper layers, cardboard tubes, tubes formed using a paper-mâché type process, molded or extruded plastic tubes, or the like.

[0164] In some embodiments, the tubular portion has a wall thickness of at least about 150 μm and at most about 2 mm, between 200 μm and 1.5 mm, or between 250 μm and 1 mm. For example, the tubular portion may have a wall thickness of about 300 μm. The “wall thickness” of the tubular portion corresponds to the thickness of the wall of the tubular portion in the radial direction. This can be measured, for example, using calipers.

[0165] In an example where the nozzle includes a tubular portion, the vent 12 can be arranged to directly provide ventilation into the tubular portion.

[0166] In some examples, the pressure drop across the length of nozzle 2 is less than about 20 mmH2O. In some examples, particularly improved aerosols are achieved in articles used with a non-flammable aerosol supply system having a pressure drop of less than 15 mmH2O, for example, about 6 mmH2O, about 10 mmH2O, or about 14 mmH2O. Alternatively or additionally, the nozzle pressure drop may be at least 3 mmH2O, at least 4 mmH2O, or at least 5 mmH2O. In some embodiments, the nozzle pressure drop may be between about 5 mmH2O and 20 mmH2O, or between 5 mmH2O and 15 mmH2O. These values ​​allow nozzle 2 to slow down the aerosol as it passes through nozzle 2, giving the aerosol temperature time to decrease before reaching the downstream end 2b of nozzle 2.

[0167] The ventilation level of articles 1 and 1' can be increased for articles intended for use with a non-flammable aerosol supply system. For example, the ventilation level can be about 75% of the aerosol drawn through the article. In alternative embodiments, the article can have a ventilation level of 50% to 80%, for example 65% to 75%, of the aerosol drawn through the article. Ventilation at these levels helps to slow the flow of aerosol drawn through nozzle 2 and thus allows the aerosol to be adequately cooled before reaching the downstream end 2b of nozzle 2. This can be particularly advantageous when ventilation is provided into the tubular portion. Ventilation is provided directly into nozzle 2 of article 1.

[0168] In the example of providing a tubular portion, ventilation may be provided into the wall of the tubular portion. Ventilation is provided via first and second parallel rows of ventilation holes 12, which are appropriately shaped as laser perforations. These ventilation holes 12 pass through the tipping paper 5 and any forming paper surrounding the tubular portion to provide ventilation into the tubular portion. In an alternative embodiment, ventilation may be provided into the nozzle at other locations.

[0169] In some embodiments, the wrapper 10 preferably has a permeability of less than 100 coresta units, more preferably less than 60 coresta units. It has been found that low-permeability wrappers (e.g., with a permeability of less than 100 coresta units, more preferably less than 60 coresta units) result in improved aerosol formation in the aerosol-generating material 3 of the non-flammable aerosol supply system. Without wishing to be bound by theory, it is assumed that this is due to a reduction in the loss of aerosol compounds through the wrapper 10. The permeability of the wrapper 10 can be measured according to ISO 2965:2019, relating to the determination of the permeability of materials used as cigarette paper, filter forming paper, and filter connecting paper.

[0170] In some embodiments, the wrapper 10 comprises aluminum foil. Aluminum foil has been found to be particularly effective in enhancing aerosol formation within the aerosol generating material 3 in a non-flammable aerosol supply system. In some examples, the aluminum foil has a metal layer with a thickness of about 6 μm. In some examples, the aluminum foil has a paper backing. In alternative arrangements, the aluminum foil can be of other thicknesses, for example, between 4 μm and 16 μm. The aluminum foil does not necessarily need to have a paper backing, but can have a backing formed of other materials, for example, to help provide the foil with appropriate tensile strength, or it may not have a backing material. Metal layers or foils other than aluminum can also be used. The total thickness of the wrapper can be between 20 μm and 60 μm, for example between 30 μm and 50 μm, which can provide a wrapper with appropriate structural integrity and thermal transfer properties. The tensile force that can be applied to the package before it breaks can be greater than 3,000 gf, for example, between 3,000 gf and 10,000 gf or between 3,000 gf and 4,500 gf.

[0171] In some examples, the encapsulation 10 surrounding the aerosol generating material 3 has a high level of permeability, such as greater than about 1,000 Coresta units, or greater than about 1,500 Coresta units, or greater than about 2,000 Coresta units.

[0172] The encapsulation 10 can be formed of a material with a high inherent permeability level, an inherently porous material, or a material with any inherent permeability level, wherein the final permeability level is achieved by providing a permeable zone or area for the encapsulation 10. Providing a permeable encapsulation 10 provides a path for air to enter the article. The encapsulation 10 can be configured to be permeable such that the amount of air entering through the rod of the aerosol generating material is relatively greater than the amount of air entering the article through the vent 12 in the nozzle. Articles with this arrangement can produce a more palatable aerosol, which can lead to greater user satisfaction.

[0173] In some examples, the aerosol forming agent material added to the aerosol generating matrix 3 comprises 14% by weight of the aerosol generating matrix 3. In articles used in non-flammable aerosol supply systems, the aerosol forming agent material preferably comprises at least 5% by weight of the aerosol generating matrix, more preferably at least 10%. Preferably, the aerosol forming agent material comprises less than 25% by weight of the aerosol generating matrix, more preferably less than 20%, for example, between 10% and 20%, between 12% and 18%, or between 13% and 16%.

[0174] In the tobacco materials described herein, the tobacco component may comprise paper-processed reconstituted tobacco. The tobacco component may also comprise tobacco leaves, extruded tobacco, and / or ribbon-cast tobacco.

[0175] In this example, the rod of the aerosol-generating material has a circumference of approximately 24 mm. In other examples, particularly for articles used in non-flammable aerosol supply systems, articles 1 and 1' may have a rod of aerosol-generating material having a circumference greater than 19 mm. It has been found that this provides sufficient circumference to generate improved and sustained aerosols during the consumer-preferred conventional aerosol generation period. When the article is heated, heat is transferred through the rod of the aerosol-generating material 3 to cause the components of the rod to volatilize, and it has been found that a circumference greater than 19 mm is particularly effective in generating aerosols in this manner in non-flammable aerosol supply systems. Since the article will be heated to release aerosols, improved heating efficiency can be achieved by using an article with a circumference of less than approximately 23 mm. To achieve improved aerosols via heating while maintaining a suitable product length, a rod circumference greater than 19 mm and less than 23 mm is preferred for use in non-flammable aerosol supply systems. In some examples, the rod circumference can be between 20 mm and 22 mm, which has been found to provide a good balance between providing efficient aerosol delivery and allowing for efficient heating.

[0176] Figure 2 This is a side cross-sectional view of another article 1' including nozzle 2'. Nozzle 2' is substantially the same as nozzle 2, except that: the second section 6' includes an aerosol modifier release assembly. In this example, the aerosol modifier release assembly is provided in the form of capsule 11.

[0177] In some examples, multiple capsules 11 can be set.

[0178] In some examples, the nozzle 2' may include an aerosol modifier release assembly operable to release an aerosol modifier. In some embodiments, the aerosol modifier release assembly may be operable to selectively release an aerosol modifier.

[0179] For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers can include one or more of flavoring agents, coloring agents, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter materials.

[0180] In some examples, the aerosol modifier release assembly may be, for example, a thread or a bead. In some embodiments, multiple aerosol modifier release assemblies are provided, and may include multiple charcoal particles loaded with aerosol modifier.

[0181] In some embodiments, the aerosol modifier release assembly includes a thread loaded with the additive. The thread may be made of fibers such as cellulose acetate or cotton.

[0182] In some embodiments, the aerosol-modified release component has an aerosol modifier in the range of 1 mg to 20 mg, for example, an aerosol modifier in the range of 2 mg to 15 mg.

[0183] In this example, capsule 11 is located in the second segment 6. In this example, capsule 11 is embedded in the sheet material forming the second aggregate of the second segment 6.

[0184] In other examples, the (or each) aerosol modifier release component may be combined with the sheet material of the second aggregate, for example, adhered to the sheet material of the second aggregate, before the sheet material of the second aggregate is formed into the second segment 6'.

[0185] In some embodiments, a user can selectively rupture the capsule 11 by applying external force to the mouthpiece 2' to release the aerosol modifier from the capsule. In these cases, the second segment 6 has a higher suction resistance than the first segment 4, which can facilitate precise positioning of the capsule 11 within the segment 6 because the second aggregated sheet material is more uniformly distributed across the cross-section of the second segment 6 compared to the first aggregated sheet material of the first segment 4. The second segment 6 has a second aggregated sheet material 6A, which can have a larger unfolded width than the first aggregated sheet material 4A and can also have a higher packing density than the first segment 4. This means that the capsule 11 is easier for the consumer to rupture and helps to transfer the compressive force applied by the consumer to the capsule 11. The higher packing density of the second segment 6 also results in a higher surface area of ​​the material into which the contents of the capsule 11 (such as liquid contents) can penetrate and disperse upon rupture of the capsule 11. The higher surface area can thereby improve the release of the aerosol modifier into the aerosol passing through the second segment 6.

[0186] In some implementations, the (or each) capsule includes an outer shell and an inner core.

[0187] The shell of each capsule may be solid at room temperature. The shell may comprise, be composed of, or be substantially composed of alginate. However, it should be recognized that in alternative embodiments, the shell is formed from different materials. For example, the shell may alternatively comprise, be composed of, or be substantially composed of gelatin, carrageenan, or pectin. The shell may comprise one or more of alginate, gelatin, carrageenan, or pectin, be composed of, or be substantially composed of, one or more of alginate, gelatin, carrageenan, or pectin.

[0188] The shell of each additive capsule can be impermeable to, or substantially impermeable to, the aerosol modifier in the core. Therefore, the shell initially prevents the reagent in the core from escaping from the capsule. When the user desires modified aerosols, the capsule shell ruptures, allowing the reagent to be released.

[0189] In some embodiments (not shown), the capsule (or each) further includes a carrier material. The carrier material may include, for example, gelatin.

[0190] In some embodiments, the capsule (or each capsule) has a diameter in the range of 1 mm to 5 mm, or in the range of 2 mm to 4 mm. In some embodiments, the diameter of the capsule (or each capsule) is about 3 mm. The capsule (or each capsule) may be substantially spherical. In other examples, capsules of other shapes and sizes may be used.

[0191] The total weight of each capsule may range from about 5 mg to about 50 mg, or from about 10 mg to about 30 mg. In some embodiments, each capsule has a weight of about 14 mg.

[0192] In some embodiments, one or more aerosol modifier release barriers are included in the second segment 6', wherein the second segment 6' is formed of a sheet material having a basis weight of less than 40 gsm, for example less than 35 gsm or 30 gsm. This helps to reduce the density of the second segment 6' to compensate for the presence of the aerosol modifier release components within the second segment 6', which could otherwise cause an increase in the robustness of the second segment 6'.

[0193] In some embodiments, one or more aerosol modifier release components are included in the second segment 6', wherein the second segment 6' is formed of a sheet material having a width of less than 100 mm, for example less than 90 mm or 80 mm. This helps to reduce the density of the second segment 6' to compensate for the presence of the aerosol modifier release components within the second segment 6', which could otherwise cause an increase in the robustness of the second segment 6'.

[0194] In some embodiments, the capsule (or each capsule) is centered on the longitudinal axis of the mouthpiece 2.
