Description

[Technical Field]

[0001] The present invention relates to components for use in aerosol delivery systems, articles, and aerosol delivery systems. [Background technology]

[0002] Certain tobacco industry products generate an aerosol during use, which is inhaled by the user. 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 combusted to form the aerosol. Such tobacco industry products typically include a mouthpiece through which the aerosol passes to the user's mouth. Summary of the Invention

[Figure 1B] 1B is a cross-sectional end view of a section formed from the gathered sheet material of FIG. 1A taken along line XX'. [Figure 1C] FIG. 1C is a side view of the sheet material forming the section of FIG. 1B.

DETAILED DESCRIPTION OF THE INVENTION

[0055] According to this disclosure, "aerosol delivery system" includes both combustion and non-combustion aerosol delivery systems.

[0056] According to the present disclosure, a "combustion-based" aerosol delivery system is one in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are combusted or burned during use to facilitate delivery of at least one substance to a user.

[0057] In some embodiments, the delivery system is a combustion aerosol delivery system, such as a system selected from the group consisting of a cigarette, a cigarillo, and a cigar.

[0058] In some embodiments, the present disclosure relates to aerosol modifier-releasing components such as filters, filter rods, filter segments, tobacco rods, spills, capsules, threads, or beads, or papers such as plug wrap, tipping paper, or cigarette paper, for use in combustion-based aerosol delivery systems.

[0059] Articles, for example rod-shaped articles, are often designated according to the length of the product as "regular" (typically in the 68-75 mm range, e.g., about 68 mm to about 72 mm), "short" or "mini" (68 mm or less), "king size" (typically in the 75-91 mm range, e.g., about 79 mm to about 88 mm), "long" or "super king" (typically in the 91-105 mm range, e.g., about 94 mm to about 101 mm), and "ultra long" (typically in the range of about 110 mm to about 121 mm).

[0060] Articles are also named according to the circumference of the product: "regular" (approximately 23-25 ​​mm), "wide" (over 25 mm), "slim" (approximately 22-23 mm), "demi-slim" (approximately 19-22 mm), "super slim" (approximately 16-19 mm), and "micro slim" (less than approximately 16 mm).

[0061] Thus, a king size super slim format article, for example, has a length of about 83 mm and a circumference of about 17 mm.

[0062] Each format may be manufactured with a different length of tip. The tip length may be about 14 mm to 27 mm. The tipping paper connects the tipping to the aerosol-generating material, for example in the form of a rod of substrate material, such that the tipping paper covers the tipping and overlaps the aerosol-generating material, for example in the form of a rod of substrate material, connecting the tipping to the rod, and is typically longer than the tipping paper, for example 3 to 10 mm longer.

[0063] The articles and aerosol-forming materials and mouthpieces of the articles described herein can be made in any of the formats described above, but are not limited to these.

[0064] As used herein, the terms "upstream" and "downstream" are relative terms defined with respect to the direction of mainstream aerosol drawn through an article or device in use.

[0065] As used herein, the term "tobacco material" refers to any material containing tobacco or its derivatives or substitutes. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The tobacco material may include one or more of ground tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stems, tobacco lamina, reconstituted tobacco, and / or tobacco extract.

[0066] In the figures described herein, the same reference numerals are used to denote equivalent features, items or components.

[0067] FIG. 1A is a side cross-sectional view of an article including a component having a section formed from gathered sheet material disposed at the mouth end of the article.

[0068] Article 1 includes a cylindrical rod of aerosol-forming material 3 (in this case, tobacco material) and a downstream portion (in this case, called tipping point 2) connected to the rod of aerosol-forming material 3 so as to be downstream of the aerosol-forming material. The aerosol-forming material 3 provides an aerosol when heated, for example, in a non-combustion aerosol-delivery device. In other embodiments, article 1 can include its own heat source, forming an aerosol-delivery system without the need for a separate aerosol-delivery device.

[0069] In this example, the component, in this case mouthpiece 2, includes a first section 4 located at the mouth end of the article and a second section 6 located upstream of the first section 4 between the first section 4 and the rod of aerosol-generating material 3. The first section 4 comprises a body of material formed from gathered sheet material 4A. The sheet material 4A may be folded to form the first section 4. The first section 4 may be formed from a continuous web of sheet material. In this example, the sheet material 4A is gathered to form the first section 4 in a manner similar to a "crepe filter." The gathered sheet material 4A defines a plurality of longitudinally extending passages through the first section 4.

[0070] The first section 4 may be manufactured using a Decouflé™ CU-20 filter making machine, although those skilled in the art will recognize that other machines may be used to manufacture the first section 4.

[0071] The body of material is surrounded by a first plug wrap 7. The inner surface of the plug wrap 7 defines an inner diameter "d" of the first section 4, as shown in Figure 1B.

[0072] In some embodiments, the first plug wrap 7 has a basis weight of 60 gsm to 120 gsm, for example, 70 gsm to 80 gsm. Such basis weights have been found to provide a suitable level of firmness for the tipping. In some embodiments, the basis weight of the first plug wrap 7 may 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 plug wrap 7 has a basis weight of 50 gsm to 90 gsm and a hardness of 0.5 g / cm. 3 It may have a density of less than 1000 .mu.m.

[0073] The first plug wrap 7 may have a basis weight of, for example, 50 to 90 gsm and a thickness of 0.5 g / cm 3 The first section 4 may be a breathable packaging material having a density of less than 100 Coresta units. The first section 4 may have a hardness of greater than 90%. The first plugwrap 7 may have a breathability of greater than 100 Coresta units or greater than 500 Coresta units, for example.

[0074] In some embodiments, the first plug wrap 7 has a thickness of 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be appreciated that the thickness or weight of the first plug wrap 7 may be greater to enhance mouthpiece hardness. In some embodiments, for example, the thickness of the first plug wrap 7 may be at least 40 microns, 50 microns, 60 microns, 70 microns, 80 microns, 90 microns, or 100 microns. In some embodiments, the thickness of the first plug wrap 7 is within the range of 40 microns to 125 microns, or within the range of 50 to 100 microns.

[0075] The width of the sheet material 4A that is gathered to form the first section 4 may have a developed width that is 5 to 30 times the inner diameter of the first section 4. The developed width refers to the width of the sheet material 4A before crimping or gathering is applied to the sheet material 4A to form the body of material, as described above. The developed width of the sheet material formed into the body of material may be determined by stretching the sheet material 4A to a position where the reduction in width due to crimping is substantially reversed.

[0076] 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.

[0077] In some embodiments, the continuous web of sheet material 4A has a developed 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.

[0078] In some embodiments, the continuous web of sheet material 4A has a developed width of at most 230 mm, at most 220 mm, at most 200 mm, at most 180 mm, at most 150 mm, at most 140 mm, at most 130 mm, at most 120 mm, or at most 100 mm.

[0079] In some embodiments, the sheet material 4A has a developed width in the range of 38 mm to 230 mm, such as 60 mm to 160 mm, such as 70 mm to 150 mm, or 80 mm to 120 mm. A developed width of the sheet material 4A near the lower end of the range stated above may be particularly suitable when the basis weight of the sheet material 4A is near the upper end of the range stated below.

[0080] In this example, the first section 4 has an inner diameter of about 7.6 mm and the gathered sheet material 4A has a developed width of about 114 mm.

[0081] In one example, the sheet material 4A may have a basis weight in the range of 20 to 120 gsm, such as 30 to 85 gsm, 30 to 65 gsm, 34 to 60 gsm, or 40 to 50 gsm.

[0082] In some embodiments, 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.

[0083] In some embodiments, 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.

[0084] There may be advantages, for example, in terms of hardness and pressure drop, in selecting a basis weight for sheet material 4A from about 70 gsm to about 120 gsm. Such sheet material may have a thickness of about 100 to about 160 microns. The density of sheet material 4A may be about 0.6 to about 0.9 gms / cm. 3 , for example, about 0.65 to about 0.75 gms / cm 3 It can be said that:

[0085] In this example, the sheet material 4A is crimped before being placed within the first section 4. For example, the sheet material 4A may be passed through a pair of crimping rollers. In this example, the first section 4 comprises a crimped sheet material 4A formed with a crimp pattern comprising a series of substantially parallel ridges and grooves. Crimping may make it easier to gather the sheet material 4A to form the first section 4. In other examples, the sheet material 4A may not be crimped.

[0086] In this example, the body of material comprises a crimped sheet material 4A having a crimp pattern comprising a series of substantially parallel ridges and grooves, with the average spacing between adjacent ridges being greater than about 0.3 mm. Additionally, in this example, the crimp amplitude is about 0.5 mm or less, or less than about 0.4 mm. In some examples, the crimp amplitude of the sheet material forming the first section 4 is less than 0.7 mm, less than 0.6 mm, less than 0.5 mm, less than 0.4 mm, less than 0.3 mm, less than 0.2 mm, or less than 0.1 mm. In some examples, the crimp amplitude of the sheet material 4A forming the first section 4 is at least 0.05 mm. For example, the crimp amplitude of the sheet material 4 forming the first section can be between about 0.1 mm and about 0.5 mm, or between about 0.15 mm and about 0.4 mm.

[0087] Crimp amplitude (also known as "crimping factor") refers to the depth of the grooves that the crimping creates in the sheet material forming the body. That is, as shown in FIG. 1C, crimping the sheet material creates multiple peaks and valleys in the sheet material when viewed from a first side of the sheet material, and the crimp amplitude "A" is the depth of the valleys measured from the peaks. The crimping may form a "zigzag" or other shape. In some embodiments, adjacent grooves in the crimped sheet material 4A are spaced apart by a distance or pitch "P" in the range of 0.3 to 2 mm, preferably in the range of 0.4 to 1 mm. In some embodiments, adjacent grooves in the crimped sheet material 4A are spaced apart by a distance of at least 0.4 mm, or at least 0.5, 0.6, 0.7, or 0.8 mm. In some embodiments, adjacent grooves of the crimped sheet material 4A are spaced apart by a distance of at most 1.5 mm, preferably at most 1.4, 1.3, 1.2, 1.1, or 1.0 mm. Adjacent grooves of the crimped sheet material 4A can be spaced apart by, for example, about 0.3 mm to about 1.2 mm, or about 0.4 mm to about 1 mm.

[0088] Each of the plurality of longitudinally extending passages through the first section 4 has a length of 3 mm 2 Less than, optionally 2 mm2 Less than or equal to 1 mm 2 Each of the plurality of passages may have a cross-sectional area of ​​less than 0.5 mm. 2 Ultra, optional 1mm 2 Over 1.5mm 2 Such a passage size can enable first section 4 to exhibit a relatively low pressure drop or draw resistance over the length of first section 4, while the visual appearance of the first section does not differ significantly from a standard cellulose acetate filter.

[0089] The first section 4 may have a pressure drop across the length of the section of 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.

[0090] In some examples, the pressure drop across the length of the first section 4 is at least 5 mmH2O, or at least 7 mmH2O, or at least 8 mmH2O, or at least 10 mmH2O.

[0091] In some examples, the pressure drop per mm over the length of the first section 4 is at least 1.1 mmH2O / mm, or at least 1.5 mmH2O / mm, or at least 2 mmH2O / mm.

[0092] The pressure drop across the length of the first section 4 may be less than 0.25 mmH2O per mm of first section length, or less than 0.20 mmH2O per mm of first section length, or less than 0.15 mmH2O per mm of first section length. The pressure drop across the length of the first section may be between 0.05 mmH2O per mm of first section length and 0.50 mmH2O per mm of first section length, or between 0.05 mmH2O per mm of first section length and 0.25 mmH2O per mm of first section length.

[0093] The pressure drop across the length of the first section, as well as other pressure drop and draw resistance values ​​defined herein, are determined in accordance with ISO standard method (ISO6565:2015). The pressure drop refers to the "closed pressure drop" where the vent zone to the article or body being measured is closed.

[0094] In some examples, the first section 4 forms the mouth end of the article. In such examples, the difference in pressure drop across the length of the article compared to the pressure drop across the length of an otherwise identical article without the first section 4 at the mouth end may be greater than the pressure drop across the length of the first section 4. For example, the first section 4 may have a pressure drop across its length of 5 mmH2O, but when added to the mouth end of the article, it may increase the pressure drop across the length of the article to more than 5 mmH2O. This is hypothesized to be due to the effect of the first section 4 on the air flow path upstream of the first section 4.

[0095] In some embodiments, the tipping 2 has a hardness in the first section 4 in the range of about 70% to 95%, or in the range of about 75% to 85%. The hardness of the tipping 2 in the first section may 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 tipping in the first section may be about 90%.

[0096] The hardness of the tipping tip 2 may be measured according to the following protocol: When referring to the hardness of a section herein, the hardness is to be determined by the following measurement process: Any suitable device may be used to perform the measurement, such as a Borgwaldt Hardness Tester H10.

[0097] Hardness is defined as the ratio of the body height h0 to the body height h1 under a defined load, expressed as a percentage of h0. Hardness may be expressed as: Hardness=(h1 / h0)×100 For individual bodies, or bodies contained in a multi-section rod, the hardness measurement is performed at the longitudinal center point of the body or multi-section rod.

[0098] A load bar is used to apply a defined load to the body. The length of the load bar should be significantly longer than the length of the specimen to be measured. Prior to the hardness measurement, the body to be measured is conditioned for a minimum of 48 hours according to ISO 3402:2023 and maintained at the environmental conditions according to ISO 3402:2023 during the measurement.

[0099] To perform the hardness measurement, the body is placed in a Hardness Tester H10, a 2g preload is applied to the body, and after 1 second, the initial height h0 of the body under the 2g preload is recorded. The preload is then removed, and a load bar supporting a 150g load is lowered onto the sample at a rate of 0.6mm / s, and after 5 seconds, the height h1 of the body under the 150g load is measured.

[0100] Tip hardness is determined as the average hardness of at least 20 tips measured according to this protocol.

[0101] The hardness of the first section 4 surrounded by the first plug wrap 7 (hereinafter collectively referred to as the "component" for purposes of determining hardness) may also be determined using the protocol described above by carefully cutting the article to remove the first section 4 surrounded by the first plug wrap 7. The hardness of the component may be at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, or at least 92%. The hardness of the component may preferably be from about 80% to about 95%.

[0102] In some cases, the first section 4 has a length of at least 4 mm, for example at least 5 mm, at least 6 mm, at least 7 mm, or at least 8 mm. In some cases, the first section has a length of less than 10 mm.

[0103] In this example, the second section 6 is positioned immediately downstream of the rod of aerosol-generating material 3. In other examples, there may be additional components between the second section 6 and the rod of aerosol-generating material 3.

[0104] The second section 6 is also formed from gathered sheet material in a similar manner as described with respect to the first section 4, and the gathered sheet material forming the second section 6 is referred to as the second gathered sheet material. The total pressure drop across the length of the second section 6 can be greater than the total pressure drop across the length of the first section 4. Alternatively or additionally, the pressure drop per mm across the length of the second section 6 can be greater than the pressure drop per mm across the length of the first section 4.

[0105] The second gathered sheet material may have the same composition as the first gathered sheet material 4A, i.e., the second gathered sheet material may be a fibrous sheet material and / or formed from a cellulosic material. In this example, the second gathered sheet material is paper. In some examples, the second gathered sheet material may be a combustible sheet material and / or a nonwoven material.

[0106] The second section is formed from a second gathered sheet material (not shown) having an unfolded width greater than the unfolded width of the sheet material forming the first section 4 .

[0107] The second section 6 may have a periphery defined by the inner surface of the second plug wrap 8 that defines the cross-sectional area of ​​the second section 6, with 1 mm of gathered sheet material within the periphery. 3The average density per square inch is generally constant across the cross-sectional area of ​​second section 6. This can be achieved through the use of crimping, which allows for relatively constant gathering of the second gathered sheet material to form second section 6.

[0108] The second gathered sheet material defines a plurality of longitudinally extending passages through the second section 6. In some examples, the cross-sectional area of ​​at least one of the passages through the second section 6 is greater than or equal to 1 mm 2 In some examples, the average cross-sectional area of ​​the plurality of passages through the second section 6 is less than 1 mm 2 In some other examples, each of the passages through the second section 6 is less than 3 mm. 2 Less than 2 mm 2 Less than or equal to 1 mm 2 The second gathered sheet material may be crimped in a manner similar to that described for the first sheet material 4A. In this example, the second gathered sheet material is crimped before being placed within the second section 6. In other examples, the second gathered sheet material may not be crimped.

[0109] In some examples, the level of crimping applied to the second gathered sheet material may allow a greater width of sheet material to be gathered into the second section 6 than the amount of sheet material gathered into the first section 4. Increasing the amount of sheet material in the second section 6 may increase the surface area of ​​the sheet material in contact with the aerosol passing through the second section 6. This may result in a greater pressure drop across the length of the second section 6 than across the first section 4. This configuration of relative pressure drops may result in the second section 6 being located upstream of the first section 4 and having a higher filtration efficiency than the first section 4. Advantageously, the relatively lower contribution of the first section 4 to aerosol filtration may reduce visible fouling of the first section 4 during use compared to the second section 6, making the appearance of the tipping tip 2 more acceptable to users.

[0110] The developed width of the first gathered sheet material may be 10mm to 100mm or 10mm to 20mm smaller than the developed width of the second gathered sheet material. The developed width of the first gathered sheet material may be 8% to 50% smaller than the width of the second gathered sheet material. The developed width of the first gathered sheet material may be 8% to 20% smaller than the width of the second gathered sheet material.

[0111] Instead of or in addition to a first section provided at the mouth end 2b, the first section 4 can be provided at the mouth end 2b or the distal upstream end of the article 1, 1′ opposite the downstream end 2b. In these cases, the first section 4 can help hold the aerosol-generating material 3 in place. In these cases, if the first section 4 is provided at the upstream end instead of the downstream end, the second section 6 can be omitted or included as a mouth-end component of the article 1, 1′. The first section 4 can provide a novel distal end appearance to the article 1, 1′. When provided at the distal end, the length of the component can be 4 mm to 8 mm, or 5 mm to 7 mm. The first section 4 can include an aerosol-former material, as defined herein, such as glycerol. Alternatively or additionally, the first section 4 can include an active substance, as defined herein, such as nicotine.

[0112] In some examples, at least one of the first section 4 or the second section 6 may be treated to change its visual appearance compared to the other of the first section 4 or the second section 6. For example, the sheet material forming the section may be bleached, stained, or otherwise altered to alter the appearance of the sheet material. This can aid in distinguishing the sections using sensors, such as optical sensors, during high-speed manufacturing.

[0113] In some examples, the pressure drop across the length of the body of material forming the second section 6 is at least 10 mmH2O, at least 15 mmH2O, or at least 20 mmH2O, at least 30 mmH2O, or at least 40 mmH2O.

[0114] In some examples, the pressure drop across the length of the body of material forming the second section 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.

[0115] In some examples, the pressure drop across the length of the body of material forming second section 6 is about 20 mmH2O, 22 mmH2O, or 25 mmH2O. In some examples, the pressure drop across the length of the body of material forming second section 6 is about 30 mmH2O, 32 mmH2O, or 35 mmH2O.

[0116] In some examples, the pressure drop across the length of the body of material forming the second section 6 is in the range of 10 mmH2O to 40 mmH2O, or in the range of 15 mmH2O to 30 mmH2O.

[0117] In some examples, the pressure drop across the length of the body of material forming second section 6 is at least 1.0 mmH2O per mm of axial length of the body of material forming second section 6. In some embodiments, the pressure drop across the length of the body of material forming second section 6 is at least 1.2 mmH2O, 1.5 mmH2O, or 1.8 mmH2O per mm of axial length of the body of material.

[0118] In some embodiments, the pressure drop across the length of the body of material forming second section 6 is less than 10 mmH2O, less than 8 mmH2O, less than 5 mmH2O, less than 3.0 mmH2O, less than 2.8 mmH2O, or less than 2.6 mmH2O per mm of axial length of the body of material. In some embodiments, the pressure drop across the length of the body of material forming second section 6 is less than 2.5 mmH2O, less than 2.4 mmH2O, or less than 2.3 mmH2O per mm of axial length of the body of material forming second section 6.

[0119] In this example, the body of material forming second section 6 comprises a crimped sheet material having a crimp pattern comprising a series of substantially parallel ridges and grooves. In this example, the crimp amplitude is between about 0.4 mm and 0.7 mm. For example, the crimp amplitude of the sheet material may be about 0.4 mm, 0.5 mm, 0.6 mm, or 0.7 mm.

[0120] In some embodiments, adjacent grooves in the crimped sheet material are spaced apart by a distance of at least 0.4 mm, or at least 0.5, 0.6, 0.7, or 0.8 mm. In some embodiments, adjacent grooves in the crimped sheet material 10 are spaced apart by a distance of at most 1.5 mm, preferably at most 1.4, 1.3, 1.2, 1.1, or 1.0 mm. For example, the sheet material can have crimps with a crimp amplitude of less than 1 mm and a spacing between peaks (or valleys) of at least 300 μm, at least 400 μm, or at least 500 μm.

[0121] In some embodiments, the continuous web of sheet material has a developed width of at least 40 mm, 50 mm, 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.

[0122] In some embodiments, the continuous web of sheet material has a developed width of at most 300 mm, at most 280 mm, at most 260 mm, at most 240 mm, at most 230 mm, at most 220 mm, at most 210 mm, at most 200 mm, or at most 190 mm.

[0123] In some examples, the developed width of the first gathered sheet material 4A may be 8% to 50% or 8% to 20% smaller than the developed width of the second gathered sheet material. For example, the developed width of the second sheet material may be approximately 170 mm, and the developed width of the first sheet material 4A may be approximately 100 mm. In this example, the developed width of the second sheet material is suitably approximately 120 mm to approximately 180 mm or approximately 124 mm to approximately 143 mm. In this example, the developed width of the second gathered sheet material may be approximately 125 mm.

[0124] The second section 6 is surrounded by a second plug wrap 8. In some embodiments, the second plug wrap 8 has a basis weight of 20 gsm to 120 gsm, for example, 40 gsm to 100 gsm, or 50 gsm to 80 gsm. The second plug wrap 8 may have, for example, a basis weight of 50 to 90 gsm and a cross-sectional area of ​​0.5 g / cm. 3 The second plugwrap 8 may be a breathable packaging material having a density of less than 100 Coresta units or greater than 500 Coresta units, for example.

[0125] In one example, the second gathered sheet material may have a basis weight in the range of 20 to 45 gsm, such as 25 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.

[0126] 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.

[0127] In some examples, the second section 6 has a length of at least 10 mm. For example, the second section 6 may have a length of at least 12 mm, at least 15 mm, at least 18 mm, or at least 20 mm.

[0128] The pressure drop or pressure differential (also referred to as resistance to draw) across the length of the mouthpiece 2 is less than about 180 mmH2O. Such a pressure drop has been found to allow sufficient aerosol containing desirable compounds, such as flavor 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, less than about 130 mmH2O, less than about 100 mmH2O, or less than 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.

[0129] In this example, ventilation is provided into second section 6. In this example, ventilation is provided by ventilation holes 12 formed through tipping paper 5, second plug wrap 8, and third plug wrap 9 to provide ventilation into second section 6.

[0130] In this example, the first section 4 and the second section 6 are surrounded by a third plug wrap 9. The third plug wrap 9 can be bonded around the article component by an adhesive applied to a lap seam extending longitudinally along the second plug wrap. Alternatively or additionally, the third plug wrap 9 can be directly bonded to the underlying component using an adhesive. In either case, the adhesive can be selected to be a water-soluble adhesive to aid in the decomposition of the component. Additionally or alternatively, the third plug wrap 9 itself can be formed from paper or other materials with improved degradability, for example, improved dispersibility when exposed to water.

[0131] In some embodiments, the third plug wrap 9 has a basis weight of less than 120 gsm. In some embodiments, the third plug wrap 9 has a basis weight of about 70 gsm to about 80 gsm. However, it should be appreciated that the basis weight of the third plug wrap 9 may be higher to increase tip stiffness. For example, the basis weight of the third plug wrap 9 may be about 60 gsm to 120 gsm.

[0132] In some embodiments, the basis weight of the third plug wrap 9 is in the range of 50 gsm to 110 gsm, or in the range of 60 gsm to 100 gsm.

[0133] In some embodiments, the third plug wrap 9 has a thickness of 30 μm to 60 μm, or 35 μm to 45 μm. However, it should be appreciated that the thickness of the third plug wrap 9 may be greater to increase the hardness of the mouthpiece. In some embodiments, for example, the thickness of the third plug wrap 9 may be at least 40 microns, at least 50 microns, at least 60 microns, at least 70 microns, at least 80 microns, at least 90 microns, or at least 100 microns. In some embodiments, the thickness of the third plug wrap 9 is in the range of 40 microns to 120 microns, or in the range of 50 microns to 100 microns.

[0134] In some embodiments, the third plug wrap 9 is a non-porous plug wrap having an air permeability of less than 100 Coresta units, for example less than 50 Coresta units. However, in alternative embodiments, the third plug wrap 9 may be a porous plug wrap having an air permeability of, for example, more than 200 Coresta units.

[0135] Each of the first section 4, the second section 6, and the tipping tip 2 may also be referred to as a component. Such components as described herein may be particularly suitable for use in or as an article tipping tip. In some examples, the tipping tip may comprise additional sections to those described herein.

[0136] Biodegradability can be measured according to the procedure set forth in ISO 14855-2:2018. Components as described herein can achieve greater than 50% biodegradation in 30 days when exposed to either freshwater or saltwater.

[0137] In some examples, the sheet material 4A forming the first section 4 may include a coating applied to the sheet material 4A prior to forming the body of material or during the process of forming the body of material. 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 rigidity of the first section 4, for example, by reinforcing the sheet material 4A or by bonding adjacent folds of the gathered sheet material 4A to one another to increase the rigidity of the body of the gathered sheet material.

[0138] In some cases, substantially the entire surface area of ​​sheet material 4A may be covered by the coating. In other cases, the coating may be applied in a pattern that varies across the surface area of ​​sheet material 4A. For example, the coating may be applied in a dot matrix pattern or may be arranged in lines across or along the surface of sheet material 4A. In some cases, the coating may be arranged to leave at least a portion of sheet material 4A uncoated.

[0139] As sheet material 4A is formed into a body of material, portions of the sheet material may contact one another, forming contact areas. In some cases, the coating on the surface of sheet material 4A may be such that the contact areas between the portions of the sheet material are reinforced or permanently adhered to one another, for example, due to bonds 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 may also provide additional rigidity to the entire surface of sheet material 4A, or to the areas of the sheet material where the coating is applied, so that a body formed from the coated sheet material may have increased hardness.

[0140] Preferably, the aerosol-forming material or substrate is formed from a tobacco material as described herein, including a tobacco component.

[0141] In this example, the aerosol-generating material 3 is enclosed in a wrapping 10. The wrapping 10 may be, for example, a paper or paper-lined foil wrapping. In this example, the wrapping 10 is breathable cigarette paper. In other examples, the wrapping 10 may be substantially non-breathable to air, particularly if the article 1 is intended for use with a non-combustion aerosol delivery system, as described further below.

[0142] 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, the aerosol-generating material preferably has a length of about 10 mm to 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 in the range of about 30 mm to 40 mm.

[0143] The tobacco material may be provided in the form of cut rag tobacco. The cut rag tobacco may have a cut width of at least 15 cuts per inch (about 5.9 cuts per cm, corresponding to a cut width of about 1.7 mm). Preferably, the cut rag tobacco has a cut width of at least 18 cuts per inch (about 7.1 cuts per cm, corresponding to a cut width of about 1.4 mm), more preferably at least 20 cuts per inch (about 7.9 cuts per cm, corresponding to a cut width of about 1.27 mm). In one example, the cut rag tobacco has a cut width of 22 cuts per inch (about 8.7 cuts per cm, corresponding to a cut width of about 1.15 mm). Preferably, the cut rag tobacco has a cut width of 40 cuts per inch or less (about 15.7 cuts per cm, corresponding to a cut width of about 0.64 mm). A cut width of 0.5 mm to 2.0 mm, for example 0.6 mm to 1.5 mm, or 0.6 mm to 1.7 mm, has been found to provide a preferred tobacco material, particularly in terms of surface area to volume ratio when heated, and overall density and pressure drop of the aerosol-forming material 3. Cut rag tobacco can be formed from a mixture of tobacco material forms, such as one or more of reconstituted tobacco, leaf tobacco, extruded tobacco, and band-cast tobacco. Preferably, the tobacco material comprises reconstituted tobacco or a mixture of reconstituted tobacco and leaf tobacco.

[0144] In the tobacco materials described herein, the tobacco material may contain a filler component. The filler component is generally a non-tobacco component, i.e., a component that does not contain tobacco-derived materials. The filler component may be a non-tobacco fiber, such as wood fiber or pulp or wheat fiber. The filler component may also be an inorganic material, such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. The filler component may also be a non-tobacco cast material or a non-tobacco extrusion material. The filler component may be present in an amount of 0-20% by weight of the tobacco material or in an amount of 1-10% by weight of the composition. In some embodiments, no filler component is present.

[0145] In the tobacco materials described herein, the tobacco material may contain an aerosol-forming agent material. In this context, an "aerosol-forming agent material" is an agent that facilitates the generation of an aerosol. The aerosol-forming agent material may facilitate the generation of an aerosol by promoting the initial vaporization and / or condensation of a gas into an inhalable solid and / or liquid aerosol. In some embodiments, the aerosol-forming agent material may improve the delivery of flavoring agents from the aerosol-forming material. In general, any suitable aerosol-forming agent material or agent, including those described herein, may be included in the aerosol-forming materials of the present invention. Other suitable aerosol-forming materials include, but are not limited to, polyols such as sorbitol, glycerol, and glycols such as propylene glycol or triethylene glycol; monohydric alcohols; high-boiling hydrocarbons; acids such as lactic acid; glycerol derivatives; esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, or myristic acid, including ethyl myristate and isopropyl myristate; and aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate, and dimethyl tetradecanedioate. In some embodiments, the aerosol-forming material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10-20% by weight of the tobacco material, for example, 13-16% by weight of the composition, or about 14% or 15% by weight of the composition. Propylene glycol, when present, may be present in an amount of 0.1-0.3% by weight of the composition.

[0146] The aerosol former material may be included in any component of the tobacco material, such as any tobacco component and / or filler component, if present. Alternatively, or additionally, the aerosol former material may be added separately to the tobacco material. In either case, the total amount of aerosol former material in the tobacco material may be as defined herein.

[0147] In some examples, the tobacco material can contain 10% to 90% by weight of tobacco, with the aerosol former material being provided in an amount of up to about 10% by weight of the tobacco. It has been found that the aerosol former material can be added at a higher weight percentage relative to another component of the tobacco material, such as a reconstituted tobacco material, to achieve an overall level of 10% to 20% by weight of the tobacco material.

[0148] The tobacco material described herein contains nicotine. The nicotine content may be 0.5 to 1.75% by weight of the tobacco material, for example, 0.8 to 1.5% by weight of the tobacco material. Additionally or alternatively, the tobacco material contains 10% to 90% by weight of tobacco leaf having a nicotine content greater than 1.5% by weight of the tobacco leaf. Preferably, the use of tobacco leaf having a nicotine content greater than 1.5% in combination with a lower nicotine base, such as reconstituted tobacco, has been found to provide a tobacco material with an adequate nicotine level but with superior sensory performance compared to the use of reconstituted tobacco alone. Tobacco leaf, such as cut rag tobacco, may have a nicotine content of 1.5% to 5% by weight of the tobacco leaf, for example.

[0149] The tobacco material described herein can contain an aerosol modifier, such as any of the flavoring agents described herein. In one embodiment, the tobacco material contains menthol to form a menthol-containing article. The tobacco material can contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, and more preferably 8 mg to 16 mg of menthol. The tobacco material can contain 2% to 8% by weight of menthol, preferably 3% to 7% by weight of menthol, and more preferably 4% to 5.5% by weight of menthol. In one embodiment, the tobacco material contains 4.7% by weight of menthol. Such high levels of menthol loading can be achieved using a high percentage of reconstituted tobacco material, for example, greater than 50% by weight of the tobacco material. Alternatively or additionally, the use of a larger amount of aerosol-forming material, e.g., tobacco material, can increase the menthol loading level, for example, about 500 mm of aerosol-forming material, such as tobacco material. 3 Over or appropriately about 1000mm 3 This can be achieved if ultra is used.

[0150] For the avoidance of doubt, when amounts are given in weight percent for the compositions described herein, this refers to a dry weight basis unless specifically indicated to the contrary. Therefore, any water that may be present in the tobacco material or any of its components is completely ignored for purposes of determining weight percent. The moisture content of the tobacco material described herein may vary, e.g., 5-15% by weight. The moisture content of the tobacco material described herein may vary, for example, according to the temperature, pressure, and humidity conditions under which the composition is maintained. The moisture content can be determined by Karl Fischer analysis, as known to those skilled in the art. Meanwhile, for the avoidance of doubt, any component other than water is included in the weight of the tobacco material, even when the aerosol former material is a liquid-phase component, such as glycerol or propylene glycol. However, when an aerosol former material is provided in the tobacco component of the tobacco material or in the filler component (if present) of the tobacco material instead of or in addition to being separately added to the tobacco material, the aerosol former material is not included in the weight of the tobacco component or filler component, but is included in the weight of the "aerosol former material" in weight percent terms as defined herein. All other materials present in the tobacco component are included in the weight of the tobacco component, even if they are of non-tobacco origin (eg, non-tobacco fiber in the case of reconstituted tobacco).

[0151] In one embodiment, the tobacco material comprises a tobacco component as defined herein and an aerosol former material as defined herein. In one embodiment, the tobacco material consists essentially of a tobacco component as defined herein and an aerosol former material as defined herein. In one embodiment, the tobacco material consists of a tobacco component as defined herein and an aerosol former material as defined herein.

[0152] The paper reconstituted tobacco may be present in the tobacco component of the tobacco material described herein in an amount of 10% to 100% by weight of the tobacco component. In some embodiments, the paper reconstituted tobacco is present in an amount of 10% to 80% by weight, or 20% to 70% by weight of the tobacco component. In further embodiments, the tobacco component consists essentially of paper reconstituted tobacco or consists of paper reconstituted tobacco. In a preferred embodiment, leaf tobacco is present in the tobacco component of the tobacco material in an amount of at least 10% by weight of the tobacco component. For example, leaf tobacco can be present in an amount of at least 10% by weight of the tobacco component, with the remainder of the tobacco component comprising paper reconstituted tobacco, band-cast reconstituted tobacco, or a combination of band-cast reconstituted tobacco and another form of tobacco, such as tobacco granules.

[0153] Paper reconstituted tobacco refers to tobacco material formed by a process in which raw tobacco material is extracted with a solvent to obtain an extract of soluble substances and a residue containing fibrous material, and then the extract (usually after concentration, and optionally after further processing) is recombined with fibrous material from the residue (usually after purifying the fibrous material, and optionally with the addition of some non-tobacco fiber) by deposition of the extract onto the fibrous material. The recombination process is similar to the process for making paper.

[0154] The reconstituted tobacco paper may be any type of reconstituted tobacco paper known in the art.In certain embodiments, the reconstituted tobacco paper is made from raw materials including one or more of tobacco strips, tobacco stems, and whole leaf tobacco.In further embodiments, the reconstituted tobacco paper is made from raw materials consisting of tobacco strips and / or whole leaf tobacco, and tobacco stems.However, in other embodiments, instead of or in addition, waste, fines, and rice husks can be used as raw materials.

[0155] Paper reconstituted tobacco for use in the tobacco materials described herein may be prepared by methods known to those skilled in the art for preparing paper reconstituted tobacco.

[0156] In this example, article 1 has a circumference of about 24.8 mm (ie the article is regular format).

[0157] The circumference of the mouthpiece 2 is substantially the same as the circumference of the rod of aerosol-forming material 3 so that there is a smooth transition between these components.

[0158] In some examples, the tipping paper 5 includes a citrate, such as sodium citrate or potassium citrate. In such examples, the tipping paper 5 may have a citrate content of 2% by weight or less, or 1% by weight or less. It is believed that reducing the citrate content of the tipping paper 5 helps reduce the charring effect that can occur in non-combustion aerosol delivery systems during use.

[0159] In this example, the tipping paper 5 extends 5 mm over the rod of aerosol-generating material 3, but alternatively, it may extend 3 mm to 10 mm, or more preferably 4 mm to 6 mm, over the rod 3 to provide a secure attachment between the tipping tip 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, 50 gsm to 70 gsm, for example, 58 gsm. Basis weights in these ranges have been found to provide tipping paper with acceptable tensile strength while also being flexible enough to wrap around the article 1 and adhere to itself along the paper's longitudinal lap seam. In this example, the circumference of the tipping paper 5, when wrapped around the tipping tip 2, is approximately 24 mm.

[0160] In some examples, the articles 1, 1' described herein may be modified for use in or as a non-combustion aerosol delivery system. Modifications may be made to one or more of the wrapping material, the composition of the aerosol-generating material, and / or the configuration of the tipping component to produce an article particularly suitable for use in or as a non-combustion aerosol delivery system. For example, as described below, a tubular portion may be provided to function as a cooling segment for an article intended for use in a non-combustion aerosol delivery system. The wrapping material 10 surrounding the aerosol-generating material may suitably be substantially impermeable to air in an article for a non-combustion aerosol delivery system. Those skilled in the art will also recognize appropriate modifications to the composition of the aerosol-generating material, e.g., the inclusion of an aerosol-forming agent. The following sections describe features that may be particularly suitable for use in articles for use in non-combustion aerosol delivery systems.

[0161] The mouthpiece length may also be longer for articles intended for use in or as non-combustion aerosol delivery systems. For example, the mouthpiece length for a non-combustion aerosol delivery system may be about 30 mm to about 50 mm. Although not shown, a tubular portion may be provided downstream of the aerosol-forming material, for example, between the rod of aerosol-forming material 3 and the second section 6. The tubular portion may be referred to herein as a "cooling element."

[0162] The tubular portion is disposed around the mouthpiece and defines a cavity within the mouthpiece that functions as a cooling segment. The cavity 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 accumulation, yet is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and use of the article. The tubular portion provides a physical displacement between the aerosol-generating material 3 and the second section 6. The physical displacement provided by the tubular portion provides a thermal gradient across the length of the tubular portion.

[0163] In some embodiments, the mouthpiece is 450 mm 3 The mouthpiece comprises a cavity having an internal volume of greater than 500 mm. It has been found that providing a cavity of at least this volume allows for improved aerosol formation. Such a cavity size provides sufficient space within the mouthpiece to allow heated volatile components to cool, as this may result in an excessively warm aerosol, and therefore expose the aerosol-generating material 3 to higher temperatures than would otherwise be possible. Suitably, the cavity is formed by the tubular portion, although in alternative configurations, the cavity could be formed within a different portion of the mouthpiece. In some embodiments, the mouthpiece comprises a 500 mm cavity, for example formed within the tubular portion. 3 Ultra, for example 550mm 3 In some embodiments, the internal cavity has an internal volume of about 550 mm 3 ~about 850mm 3 , or approximately 600 mm 3 ~approx. 800mm 3 Includes the volume of

[0164] The tubular portion can be configured to provide a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the tubular portion and the heated volatile components 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 components entering the first upstream end of the tubular portion and the heated volatile components exiting the second downstream end of the tubular portion.

[0165] In some cases, the tubular portion is formed from multiple layers of paper that are wound parallel with butted seams to form a hollow tube. For example, a first and second paper layer of a two-ply tube may be provided, while in other cases, three, four, or more paper layers forming a three-, four-, or more-ply tube may be used. Other constructions may be used, such as spirally wound paper layers, cardboard tubes, tubes formed using a paper mache process, molded or extruded plastic tubes, etc.

[0166] In some embodiments, the tubular portion has a wall thickness of at least about 150 μm and up to about 2 mm, 200 μm and 1.5 mm, or 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 radial thickness of the wall of the tubular portion. This may be measured, for example, using a caliper.

[0167] In instances where the mouthpiece includes a tubular portion, the vent 12 may be positioned to provide direct ventilation into the tubular portion.

[0168] In some examples, the pressure drop across the length of the tipping 2 is less than about 20 mmH2O. In some examples, particularly improved aerosols have been achieved in articles for use with non-combustion aerosol delivery systems using tippings 2 having pressure drops of less than 15 mmH2O, e.g., about 6 mmH2O, about 10 mmH2O, or about 14 mmH2O. Alternatively or additionally, the tipping pressure drop can be at least 3 mmH2O, at least 4 mmH2O, or at least 5 mmH2O. In some embodiments, the tipping pressure drop can be between about 5 mmH2O and 20 mmH2O, or between 5 mmH2O and 15 mmH2O. These values ​​allow the tipping 2 to decelerate the aerosol as it passes through the tipping 2 so that the aerosol's temperature has time to decrease before reaching the downstream end 2b of the tipping 2.

[0169] The ventilation level of the articles 1, 1' may be increased for articles intended for use with non-combustion aerosol delivery systems. For example, the ventilation level may be about 75% of the aerosol drawn through the article. In alternative embodiments, the article may have a ventilation level of 50% to 80%, e.g., 65% to 75%, of the aerosol drawn through the article. These levels of ventilation serve to slow the flow of aerosol drawn through the mouthpiece 2, thereby allowing the aerosol to cool sufficiently before reaching the downstream end 2b of the mouthpiece 2. This may be particularly suitable when ventilation into the tubular portion is implemented. Direct ventilation into the mouthpiece 2 of the article 1 is implemented.

[0170] In instances where a tubular portion is provided, the vent may be provided within the wall of the tubular portion. Ventilation is achieved by first and second parallel rows of vent holes 12, suitably formed as laser drilling. These vent holes 12 penetrate the tipping paper 5 and any plug wrap surrounding the tubular portion to provide ventilation within the tubular portion. In alternative embodiments, ventilation within the mouthpiece can be achieved at other locations.

[0171] In some embodiments, wrapping material 10 preferably has an air permeability of less than 100 Coresta units, more preferably less than 60 Coresta units. It has been found that low-air permeability wrapping materials, for example, having an air permeability of less than 100 Coresta units, more preferably less than 60 Coresta units, result in improved aerosol formation of aerosol-generating material 3 in non-combustion aerosol delivery systems. Without wishing to be bound by theory, this is hypothesized to be due to reduced loss of aerosol compound through wrapping material 10. The air permeability of wrapping material 10 can be measured in accordance with ISO 2965:2019 for determination of air permeability of materials used as cigarette paper, filter plug wrap, and filter bonding paper.

[0172] In some embodiments, the packaging material 10 comprises aluminum foil. Aluminum foil has been found to be particularly effective in enhancing aerosol formation within the aerosol-generating material 3 in non-combustion aerosol delivery systems. In some examples, the aluminum foil has a metal layer having a thickness of approximately 6 μm. In some examples, the aluminum foil has a paper backing. In alternative configurations, the aluminum foil can be other thicknesses, for example, between 4 μm and 16 μm. The aluminum foil also need not have a paper backing, but can have a backing formed from other materials, for example, to help provide the foil with adequate tensile strength, or can have no backing material at all. Metal layers or foils other than aluminum can also be used. The total thickness of the packaging material can be between 20 μm and 60 μm, for example, between 30 μm and 50 μm, which can provide the packaging material with adequate structural integrity and heat transfer properties. The tension that can be applied to the wrapper before it breaks can be greater than 3,000 grams of force, such as 3,000 to 10,000 grams of force or 3,000 to 4,500 grams of force.

[0173] In some examples, the packaging 10 surrounding the aerosol-forming material 3 has a high level of breathability, for example, greater than about 1000 Coresta units, or greater than about 1500 Coresta units, or greater than about 2000 Coresta units.

[0174] The wrapper 10 may be formed from a material with a high inherent level of breathability, an inherently porous material, or any level of inherent breathability where the final level of breathability is achieved by providing breathable zones or regions in the wrapper 10. Providing a breathable wrapper 10 provides a pathway for air to enter the article. The wrapper 10 can be made breathable so that the amount of air entering through the rod of aerosol-forming material is relatively greater than the amount of air entering the article through the mouthpiece vent 12. Articles having this configuration may produce a more flavorful aerosol that is more satisfying to the user.

[0175] In some examples, the aerosol former material added to the aerosol-generating substrate 3 constitutes 14% by weight of the aerosol-generating substrate 3. In articles for use in non-combustion aerosol delivery systems, the aerosol former material preferably constitutes at least 5% by weight, more preferably at least 10% by weight, of the aerosol-generating substrate. Preferably, the aerosol former material constitutes less than 25% by weight, more preferably less than 20%, for example, 10% to 20%, 12% to 18%, or 13% to 16% of the aerosol-generating substrate.

[0176] In the tobacco materials described herein, the tobacco component may include paper reconstituted tobacco. The tobacco component may also include leaf tobacco, extruded tobacco, and / or band-cast tobacco.

[0177] In this example, the rod of aerosol-generating material has a circumference of approximately 24 mm. In other examples, particularly in articles for use in non-combustion aerosol delivery systems, the articles 1, 1′ may have a rod of aerosol-generating material with a circumference greater than 19 mm. This has been found to provide a sufficient circumference to generate improved, sustained aerosol over a typical aerosol-generating session preferred by consumers. When the article is heated, heat is transferred through the rod of aerosol-generating material 3, volatilizing the rod's components, and circumferences greater than 19 mm have been found to be particularly effective for generating aerosol in this manner in non-combustion aerosol delivery systems. Because the article will be heated to emit an aerosol, improved heating efficiency can be achieved by using an article with a circumference less than approximately 23 mm. To achieve improved aerosol upon heating while maintaining an adequate product length, rod circumferences greater than 19 mm and less than 23 mm are preferred for use in non-combustion aerosol delivery systems. In some cases, the rod circumference can be 20 mm to 22 mm, which has been found to provide a good balance between providing effective aerosol delivery while at the same time allowing for efficient heating.

[0178] 2 is a cross-sectional side view of a further article 1' comprising a tipping tip 2'. Tipping tip 2' is substantially similar to tipping tip 2, except that second section 6' comprises an aerosol modifier-releasing component. In this example, the aerosol modifier-releasing component is provided in the form of a capsule 11.

[0179] In some cases, multiple capsules 11 may be provided.

[0180] In some examples, mouthpiece 2' may comprise an aerosol modifier-releasing component operable to release an aerosol modifier. In some embodiments, the aerosol modifier-releasing component may be operable to selectively release the aerosol modifier.

[0181] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may include, for example, one or more of a flavoring, a colorant, water, and a carbon adsorbent. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, a string, or granules. The aerosol modifier may not include a filtering material.

[0182] In some examples, the aerosol modifier-releasing component may be, for example, a thread or a bead. In some embodiments, a plurality of aerosol modifier-releasing components are provided, and the plurality of aerosol modifier-releasing components may comprise a plurality of charcoal particles loaded with the aerosol modifier.

[0183] In some embodiments, the aerosol modifier-releasing component comprises an additive-loaded thread, which may be made from, for example, cellulose acetate or cotton fibers.

[0184] In some embodiments, the aerosol-modifying release component has in the range of 1 mg to 20 mg of aerosol modifier, such as in the range of 2 mg to 15 mg of aerosol modifier.

[0185] In this example, the capsules 11 are disposed within the second section 6. In this example, the capsules 11 are embedded in the second gathered sheet material that forms the second section 6.

[0186] In other examples, the aerosol modifier-emitting component (or each aerosol modifier-emitting component) may be combined with, e.g., adhered to, the second gathered sheet material before the second gathered sheet material is formed into the second section 6′.

[0187] In some embodiments, a user can selectively rupture capsule 11 by applying an external force to mouthpiece 2' to release the aerosol modifier from the capsule. In these cases, second section 6, which has a higher retraction resistance than first section 4, can facilitate accurate placement of capsule 11 within section 6 because the second gathered sheet material is more uniformly distributed across the cross section of second section 6 compared to the first gathered sheet material of first section 4. Second section 6, which has second gathered sheet material 6A that can have a wider deployed width than first gathered sheet material 4A, can also have a higher bulk density than first section 4, which means that capsule 11 is easier for the consumer to rupture and helps transfer the compressive force applied by the consumer to capsule 11. The higher bulk density of second section 6 can also provide a higher surface area of ​​material through which the contents of capsule 11, such as liquid contents, can be absorbed and dispersed upon rupture of capsule 11. The higher surface area may thereby improve the release of the aerosol-modifying additive into the aerosol passing through the second section 6 .

[0188] In some embodiments, the capsule (or each capsule) comprises an outer shell and an inner core.

[0189] The shell of each capsule may be solid at room temperature. The shell may include, consist of, or consist essentially of alginate. However, it should be appreciated that in alternative embodiments, the shell is formed from a different material. For example, the shell may alternatively include, consist of, or consist essentially of gelatin, carrageenan, or pectin. The shell may include, consist of, or consist essentially of one or more of alginate, gelatin, carrageenan, or pectin.

[0190] The shell of each additive capsule may be impermeable or substantially impermeable to the core aerosol-modifying agent. Thus, the shell initially prevents the core agent from escaping the capsule. When a user desires to modify the aerosol, the capsule shell is ruptured to release the agent.

[0191] In some embodiments (not shown), the capsule (or each capsule) further comprises a carrier material, which may include, for example, gelatin.

[0192] 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 generally spherical. In other examples, other shapes and sizes of capsules may be used.

[0193] The total weight of each capsule may be in the range of about 5 mg to about 50 mg, or in the range of about 10 mg to about 30 mg, hi some embodiments, each capsule weighs about 14 mg.

[0194] In some embodiments, one or more aerosol modifier-releasing components are included in second section 6′, which is formed from a sheet material having a basis weight of less than 40 gsm, for example, less than 35 or 30 gsm. This helps to reduce the density of second section 6′ to compensate for the presence of the aerosol modifier-releasing components in second section 6′, which may otherwise result in an increased stiffness of second section 6′.

[0195] In some embodiments, one or more aerosol modifier-releasing components are included in second section 6′, which is formed from a sheet material having a width of less than 100 mm, for example, less than 90 mm or less than 80 mm. This helps to reduce the density of second section 6′ to compensate for the presence of aerosol modifier-releasing components in second section 6′ that might otherwise result in an increased stiffness of second section 6′.

[0196] In some embodiments, the capsule (or each capsule) is centred on the longitudinal axis of the mouthpiece 2 .
