In some embodiments, the aerosol generator is a heater configured to expose the aerosol-generating material to thermal energy to release one or more volatile substances from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from the aerosol-generating material without heating. For example, the aerosol generator may be configured to expose the aerosol-generating material to one or more of vibration, high pressure, or electrostatic energy.

[0119] Articles, for example rod-like articles, are often named according to the length of the product: "standard" (usually 68-75 mm, e.g. in the range from about 68 mm to about 72 mm), "short" or "mini" (68 mm or less), "king size" (usually 75-91 mm, e.g. in the range from about 79 mm to about 88 mm), "long" or "super king" (usually 91-105 mm, e.g. in the range from about 94 mm to about 101 mm), and "extra long" (usually in the range from about 110 mm to about 121 mm).

[0120] They are also named according to the circumference of the cigarette: "standard" (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 16 mm).

[0121] Thus, a king size extra thin standard cigarette, for example, is about 83 mm in length and about 17 mm in circumference.

[0122] Each format may be provided with a mouthpiece of different length. The length of the mouthpiece will be approximately 30mm to 50mm. The tipping paper connects the mouthpiece to the aerosol-generating material and will typically be longer than the mouthpiece, for example by 3-10mm in length, so that the tipping paper covers the mouthpiece and overlaps the aerosol-generating material, for example in the form of a rod of substrate, connecting the mouthpiece to the rod.

[0123] The articles, aerosol generating materials and mouthpieces described herein can be made in any of the formats described above, but are not limited to these.

[0124] As used herein, the terms "upstream" and "downstream" are relative terms defined with respect to the direction of mainstream smoke aerosol-generating material being drawn through an article or device in use.

[0125] The filamentary tow material described herein may include cellulose acetate fiber tow. The filamentary tow material may be formed using other materials used to form fibers, such as polyvinyl alcohol (PVOH), polylactic acid (PLA), polycaprolactone (PCL), poly(1,4-butanediol succinate) (PBS), poly(butylene adipate-co-terephthalate) (PBAT), starch-based materials, paper, aliphatic polyester materials, and polysaccharide polymers or combinations thereof. The filamentary tow material may be plasticized with a plasticizer suitable for the filter material, such as triacetin, if the filter material is cellulose acetate tow, or may be unplasticized. The tow may be of other cross-sections, such as "Y" or "X", with fiber deniers of 2.5 to 15, e.g., 8.0 to 11.0, and 5,000 to 50,000, e.g., 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,50,51,52,53,54,55,56,57,58,59,60,61,62,63,74,75,76,77,78,79,80,81,96,97,98,99,100,110,120,130,140,150,160,170,180,190,181,192,193,194,195 Any suitable specification may be used, for example fibers having a total fineness value of 10,000 to 40,000.

[0126] 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. Tobacco material may include one or more of powdered tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stem, reconstituted tobacco and / or tobacco extract.

[0128] FIG. 1 is a cross-sectional side view of an article 1 for use in a non-combustion based aerosol delivery system.

[0129] The article 1 includes a mouthpiece 2 and a cylindrical rod of aerosol-generating material 3, in this example tobacco, connected to the mouthpiece 2. The aerosol-generating material 3 provides an aerosol when heated in a non-combustion aerosol delivery device as described herein, such as a non-combustion aerosol delivery device including, for example, a coil, forming a system. In other embodiments, the article 1 may include its own heat source for use in the aerosol delivery system, forming the aerosol delivery system without the need for a separate aerosol delivery device.

[0130] The aerosol-generating material 3, also referred to herein as aerosol-generating substrate 3, comprises at least one aerosol-forming material. In this example, the aerosol-forming material is glycerol. In another example, the aerosol-forming material may be another material or combination of materials described herein. It has been found that the aerosol-forming material enhances the sensory performance of the article by facilitating the transfer of compounds, such as flavor compounds, from the aerosol-generating material to the consumer. However, the addition of such an aerosol-forming material to the aerosol-generating material in an article for use in a non-combustion-based aerosol delivery system presents a problem in that when the aerosol-forming material is aerosolized by heating, the aerosolized aerosol-forming material increases the mass of the aerosol delivered by the article, and this increased mass maintains a higher temperature as it passes through the mouthpiece. As the aerosolized aerosol-forming material passes through the mouthpiece, the aerosol transfers heat into the mouthpiece, which heats the exterior surface of the mouthpiece, including the area that contacts the consumer's lips during use. The temperature of the mouthpiece is significantly higher than the temperature to which the consumer is accustomed when smoking, for example, a conventional cigarette, which is an undesirable effect caused by the use of such an aerosol-forming material.

[0131] The mouthpiece in this example includes a tubular portion 4a, in this example formed by a hollow tube, also referred to as a cooling member. The mouthpiece 2 includes a body of material 6 downstream of, in this example adjacent and in abutting relationship with, the tubular portion 4a. The body of material 6 and the tubular portion 4a each define a substantially cylindrical overall outer shape and share a common longitudinal axis.

[0132] The body of material 6 is wrapped in a first plug wrapper 7. In this example the tubular section 4a and body of material 6 are combined using a second plug wrapper 9 which is wrapped around both sections. Tipping paper 5 is wrapped around the entire length of the mouthpiece 2 and part of the rod of aerosol-generating material 3, has adhesive on its inner surface and connects the mouthpiece 2 to the rod 3.

[0133] In this example, the tubular portion 4a is formed from multiple layers of paper wound in parallel with joined seams to form a hollow tube. In this example, the first and second paper layers are provided in a double tube, but in other examples, three, four or more layers may be used to form a triple, quadruple or more stacked tube. Other constructions may also be used, such as spirally wound paper layers, cardboard tubes, tubes formed using a cardboard die process, molded or extruded plastic tubes, or the like.

[0134] In some embodiments, the tubular portion has a wall thickness of at least about 325 μm and no more than about 2 mm, preferably 500 μm to 1.5 mm, more preferably 750 μm to 1 mm. In this example, the wall thickness of the tubular portion is about 1 mm. The "wall thickness" of the tubular portion corresponds to the thickness of the wall of the tubular portion in the radial direction. This may be measured, for example, using a vernier caliper.

[0135] In some embodiments the wall thickness of the tubular portion is at least 325 microns, preferably at least 400, 500, 600, 700, 800, 900 or 1000 microns. In some embodiments the wall thickness of the tubular portion is at least 1250 or 1500 microns.

[0136] In some embodiments the wall thickness of the tubular portion is less than 2000 microns, preferably less than 1500 microns.

[0137] It has been found that increasing the wall thickness of the tubular portion means that it has a greater thermal mass, which helps to reduce the temperature of the aerosol passing through the tubular portion and helps to reduce the surface temperature of the mouthpiece at locations downstream of the tubular portion. It is believed that this is because the greater thermal mass of the tubular portion allows the tubular portion to absorb more heat compared to a tubular portion with a thinner wall thickness. In addition, increasing the thickness of the tubular portion forces the aerosol to flow centrally within the mouthpiece, which reduces the transfer of heat from the aerosol to the outer portions of the mouthpiece, such as the outer portions of the body of material.

[0138] In some embodiments the air permeability of the wall material of the tubular portion 4a is at least 100 Coresta units, preferably at least 500 or 1000 Coresta units.

[0139] A relatively high air permeability of the tubular portion has been found to increase the amount of heat transferred from the aerosol to the tubular portion, thus decreasing the temperature of the aerosol. The air permeability of the tubular portion has also been found to increase the amount of moisture transferred from the aerosol to the tubular portion, which has been found to improve the feel of the aerosol in the user's mouth. The high air permeability of the tubular portion makes it easier to cut ventilation holes using a laser, allowing less laser power to be used.

[0140] The article 1 has a ventilation level of about 75% of the aerosol drawn through the article. In another embodiment, the article may have a ventilation level of 50% to 80%, for example 65% to 75%, of the aerosol drawn through the article. These levels of ventilation assist in slowing down the flow of aerosol drawn through the mouthpiece 2, allowing the aerosol to cool before it reaches the downstream end 2b of the mouthpiece 2. The ventilation is provided directly within the mouthpiece 2 of the article 1. In this example, the ventilation is provided within the tubular portion 4a, which has been found to be particularly beneficial in aiding the aerosol generation process. The ventilation is provided via first and second parallel rows of ventilation holes 12, in this case formed as laser drillings, at locations 17.925 mm and 18.625 mm from the downstream mouth end 2b of the mouthpiece 2, respectively. These ventilation holes pass through the tipping paper 5, the second plug wrapper 9 and the tubular portion 4a. In another embodiment, the ventilation can be provided elsewhere within the mouthpiece. For example, the ventilation can be provided within the body of material 6.

[0141] Alternatively, ventilation may be provided via a single row of ventilation holes, e.g., laser perforations, in the portion of the article in which the tubular portion 4a is located, which is believed to result in better aerosol formation due to a more uniform air flow through the holes than multiple rows of holes for a given ventilation level.

[0142] It has been found that the aerosol temperature generally increases with decreasing ventilation level. However, the relationship between aerosol temperature and ventilation level is not linear, with differences in ventilation, for example due to manufacturing tolerances, having no effect at low target ventilation levels. For example, with a ventilation tolerance of ±15% for a target ventilation level of 75%, the aerosol temperature may increase by about 6°C at the low ventilation limit (60% ventilation). However, for a target ventilation level of 60%, the aerosol temperature increases only by about 3.5°C at the low ventilation limit (45% ventilation). The target ventilation level of the article of the invention is therefore in the range of 40% to 70%, for example 45% to 65%. This may result in an average ventilation level of 40% to 70%, for example 45% to 70% or 51% to 59% for at least 20 articles.

[0143] In some examples, the aerosol-generating material 3 described herein may be a first aerosol-generating material and the tubular portion 4a may comprise a second aerosol-generating material. In one example, the wall 4b of the tubular portion 4a comprises the second aerosol-generating material. For example, the second aerosol-generating material may be disposed on an inner surface of the tubular portion 4a.

[0144] The second aerosol-generating material includes at least one aerosol-forming material and also includes at least one aerosol modifier or other sensory material. The aerosol-forming material and / or aerosol modifier may be any or a combination of the aerosol-forming materials or aerosol modifiers described herein.

[0145] When the aerosol emitted from the aerosol-generating material 3, also referred to herein as the first aerosol, is drawn through the tubular portion 4a of the mouthpiece, heat from the first aerosol aerosolizes the aerosol-forming material of the second aerosol-generating material to generate a second aerosol. The second aerosol-generating material may include flavourants in addition to or to complement the flavour of the first aerosol-generating material.

[0146] The provision of a second aerosol-generating material in the tubular portion 4a may enhance or complement the taste or appearance of the first aerosol.

[0147] In this example, the article 1 has a circumference of about 21 mm (i.e., the article is in a demi-slim format). Preferably, the article 1 has a rod of aerosol-generating material with a circumference of greater than 19 mm. This has been found to provide a sufficient circumference to generate good and sustained aerosol over the typical aerosol generation period preferred by consumers. When the article is heated, heat is transferred through the rod of aerosol-generating material 3, volatilizing the compounds in the rod, and a circumference of greater than 19 mm has been found to be particularly effective in generating aerosol in this manner. As the article is heated to release the aerosol, good heating efficiency is achieved with an article having a circumference of less than about 23 mm. A rod circumference of greater than 19 mm and less than 23 mm is preferred to obtain good aerosol upon heating while maintaining a suitable product length. In some examples, the rod circumference may be between 20 mm and 22 mm, which provides a good combination of efficient heating and effective aerosol delivery.

[0148] The circumference of the mouthpiece 2 is substantially the same as the circumference of the rod of aerosol-generating material 3, which provides a smooth interface between these components. In this example the circumference of the mouthpiece 2 is approximately 20.8mm.

[0149] In some examples, the tipping paper 5 includes a citrate, such as sodium citrate or potassium citrate. The citrate content of such tipping paper 5 may be 2% or less by weight, or 1% or less by weight. It is believed that reducing the citrate content of the tipping paper 5 assists in reducing the scorching effect that occurs during use.

[0150] In this example the tipping paper 5 extends 5mm over the rod 3 of aerosol-generating material, but may alternatively extend 3mm-10mm, more preferably 4mm-6mm over the rod to ensure secure attachment of the mouthpiece 2 to the rod 3. The tipping paper 5 may have a basis weight greater than that of the plug wrapper used for the article 1, for example 40gsm-80gsm, more preferably 50gsm-70gsm, in this example 58gsm. Basis weights in these ranges have been found to result in a tipping paper that is flexible enough to wrap the article 1 whilst having acceptable tensile strength, and which adheres to itself along the longitudinal hold down seam of the paper. The circumference of the tipping paper 5 when wrapped around the mouthpiece 2 is approximately 21mm.

[0151] In some embodiments, the first plug wrapper 7 has a basis weight of less than 50 gsm, more preferably between about 20 gsm and 40 gsm. However, it should be recognized that the basis weight of the first plug wrapper 7 may be greater to provide a greater hardness to the mouthpiece. For example, the first plug wrapper 7 may be at least 50, 60, 70, 80, 90, or 100 gsm. In some embodiments, the basis weight of the first plug wrapper 7 is within the range of 50 to 110 gsm, or within the range of 60 to 100 gsm.

[0152] In some embodiments, the first plug wrapper 7 has a basis weight of at least 20 gsm or at least 30 gsm.

[0153] In some embodiments, the first plug wrapper 7 has a basis weight of up to 120, 110 or 100 gsm.

[0154] In some embodiments, the first plug wrapper 7 has a basis weight in the range of 20 to 120 gsm, preferably in the range of 30 to 100 gsm.

[0155] Preferably, the first plug wrapper 7 has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. However, the thickness of the first plug wrapper 7 may be greater to increase the hardness of the mouthpiece. In some embodiments, for example, the thickness of the first plug wrapper 7 may be at least 40, 50, 60, 70, 80, 90 or 100 microns. In some embodiments, the thickness of the first plug wrapper 7 is in the range of 40 to 120 microns or in the range of 50 to 100 microns.

[0156] Preferably, the first plug wrapper 7 is a non-porous plug wrapper, for example having an air permeability of less than 100 Coresta units, for example less than 50 Coresta units. However, in other embodiments the first plug wrapper 7 may be a porous plug wrapper, for example having an air permeability of more than 200 Coresta units. Preferably the length of the body of material 6 is about 20mm. In this example the length of the body of material 6 is 16mm.

[0157] In some embodiments, the axial length of the body of material 6 is in the range of 10-20 mm.

[0158] In this example, the body of material 6 is formed from a sheet of material 6A that is disposed within the body of material 6. The sheet of material 6A is folded to form the body of material 6. The body of material 6 may be formed from a continuous web of sheet material 6A. In this example, the sheet of material 6A is pleated to form the body of material 6 in a manner similar to "crepe filter paper." The sheet of material 6A is CU-20 manufactured by Decoufle™. A filter making machine may be used for production, however, it will be appreciated by those skilled in the art that other machines may be used to produce the mass 6.

[0159] In some embodiments the continuous web of sheet material 6A has a width of at least 60 mm, preferably at least 70, 80, 90, 100, 110 or 120 mm.

[0160] In some embodiments the continuous web of sheet material 6A has a width of up to 240 mm, preferably up to 230, 220, 210, 200, 190, 180, 170, 160 or 150 mm.

[0161] In some embodiments the continuous web of sheet material 6A has a width of less than 180 mm, preferably less than 170, 160, 150, 140 or 130 mm.

[0162] In some embodiments the sheet material has a width in the range of 60-240 mm, preferably in the range of 80-240 mm, in the range of 90-200 mm or in the range of 100-170 mm.

[0163] In this example, the sheet material 6A comprises cellulose. In this example, the sheet material 6A is paper. However, the sheet material 6A may additionally or alternatively comprise different materials. For example, in some embodiments, the sheet material 6A comprises reconstituted tobacco formed into a sheet material 6A configured to form the body of material 6. The reconstituted tobacco comprises cellulose. In another embodiment (not shown), the reconstituted tobacco is manufactured into a uniform plug of the material that forms the body of material 6. The reconstituted tobacco may alternatively be paper reconstituted tobacco.

[0164] In one embodiment, the sheet material 6A comprises paper having a basis weight in the range of 15 to 80 gsm, preferably in the range of 20 to 50 gsm.

[0165] In some embodiments the sheet material 6A has a basis weight of at least 15 gsm, preferably at least 20 gsm, 25 gsm, 30 gsm, 35 gsm, 40 gsm, 45 gsm, 50 gsm, 55 gsm or 60 gsm.

[0166] In some embodiments, the sheet material has a basis weight of 100 gsm or less, preferably 90 gsm or less, 80 gsm or less, 70 gsm or less, 60 gsm or less, 50 gsm or less, or 40 gsm or less, or 30 gsm or less. In some embodiments, the basis weight of the sheet material is 20 gsm or less.

[0167] In some embodiments, the sheet material has a basis weight in the range of 20 to 100 gsm, preferably in the range of 25 to 80 gsm or in the range of 30 to 65 gsm.

[0168] In some embodiments, an aerosol-forming material is applied to the body of material 6. For example, the aerosol-forming material may be applied to the sheet of material 6A before the sheet of material 6A is folded to form the body of material 6. The aerosol-forming material may be sprayed onto the sheet of material 6A or may be applied with a brush or by dipping the sheet of material 6A into the aerosol-forming material.

[0169] In some embodiments, the aerosol forming material may include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixtures, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0170] In some embodiments, at least 0.02 mg of aerosol forming material is applied to the body per mm of axial length of the body, preferably at least 0.03, 0.04 or 0.05 mg of aerosol forming material is applied to the body per mm of axial length of the body.

[0171] In some embodiments, no more than 0.5 mg of aerosol forming material is applied to the body of material per mm of axial length of the body, preferably no more than 0.4 mg, no more than 0.3 mg, no more than 0.2 mg, or no more than 0.1 mg of aerosol forming material is applied to the body of material per mm of axial length of the body.

[0172] At least a portion of the aerosol-forming material mixes with the aerosol as it passes through the body of material 6 and helps to prevent the aerosol from feeling dry in the user's mouth.

[0173] In some embodiments, the body of material 6 is at least 115 mm 3 In this example, the body of material 6 is generally cylindrical and therefore has a generally cylindrical outer volume. In another embodiment, the body of material 6 has a diameter of 115 mm 3 It should be appreciated that it may have a smaller external volume.

[0174] In this example, the width W1 of the material body 6 (corresponding to the diameter of the material body 6 in this example) is about 6.36 mm, and the axial length L1 of the material body 6 is 10 mm. Therefore, the external volume of the material body 6 is about 318 mm 3 It is.

[0175] Contains cellulose and is at least 115 mm 3 It has been found that the material 6A having a volume of 0.1 mm helps remove moisture from the aerosol generated by the aerosol-generating material 3 as the aerosol passes through the material 6A of the mouthpiece 2. That is, the cellulose comprising the sheet material 6A absorbs water from the aerosol. Removing moisture from the aerosol makes the aerosol feel cooler in the user's mouth.

[0176] In some embodiments, the body of material 6 has at least 19 mm 3 , preferably at least 25 mm per millimeter of axial length 3 or at least 30 mm per millimeter 3 For example, the volume of the material body 6 per millimeter of axial length is 19 mm 3 If the length L1 is 10 mm, the volume of the material is 190 mm 3 become.

[0177] The larger the volume of the body of material 6A, the more effective it is at removing water from the aerosol. In some examples, the outer volume of the body of material 6A is at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, or at least 1000 mm3 It is.

[0178] In some embodiments, the axial length L1 of the body of material 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, or at least 10 mm.

[0179] In some embodiments, the axial length L1 of the body of material 6 is in the range of about 5-20 mm, preferably 6-15 mm, preferably 6-10 mm.

[0180] In some embodiments, the width W1 of the body of material 6 is at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, or at least 9 mm.

[0181] In some embodiments, the circumference of the body of material 6 is at least 16 mm, at least 18 mm, at least 20 mm, at least 22 mm, at least 25 mm, or at least 28 mm.

[0182] In this example, the sheet material 6A is crimped before being configured into the body of material 6. For example, the sheet material 6A may be passed through a pair of crimping rollers. Crimping facilitates pleating the sheet material 6A to form the body of material 6. Crimping also increases the length of the sheet material 6A that is used to form a particular volume of body of material 6. Increasing the amount of sheet material 6A in the body of material 6 increases the surface area of ​​the sheet material 6A that comes into contact with the aerosol passing through the body of material 6, and therefore increases the amount of moisture absorbed from the aerosol by the sheet material 6A.

[0183] In some embodiments the sheet material is crimped to a crimp depth of at least 0.2 mm, preferably at least 0.3 mm, 0.4 mm or 0.5 mm.

[0184] In some embodiments the sheet material is crimped to a crimp depth of up to 0.8mm, preferably up to 0.6mm or 0.5mm.

[0185] Crimp depth (also known as "crimping factor") refers to the depth of the grooves formed in the sheet material by crimping. That is, when the sheet material is crimped to create valleys in the sheet material when viewed from the first side of the sheet material, the crimp depth is the depth of the valleys. The crimping may form a zigzag shape.

[0186] In some embodiments, the sheet material 6A has a basis weight in the range of 15 to 80 gsm, preferably in the range of 20 to 50 gsm.

[0187] In some embodiments, the mass 6 has a viscosity of at least 0.05 mg / mm 3 Density, preferably At least 0.07 mg / mm 3 , preferably at least 0.1 mg / mm 3 , preferably at least 0.12 mg / mm 3 or at least 0.15 mg / mm 3 In this example, the material has a density of about 0.13 mg / mm 3 It is.

[0188] In some embodiments the pressure drop across the body of material 6 is at least 2mmWG, preferably at least 3mmWG, preferably at least 4mmWG. The pressure drop across the body of material may be at least 5, 6, 7, 8, 9, 10 or 11 mmWG.

[0189] In some embodiments the pressure drop across the body of material 6 is less than 20 mmWG, preferably less than 16 mmWG, preferably less than 15, 14, 13 or 12 mmWG.

[0190] In some embodiments, the pressure drop across the body of material 6 is about 4.4, 8.1, or 11.9 mmWG. It is.

[0191] In some embodiments, the pressure drop across the body of material 6 is in the range of 3 to 15 mmWG, preferably It is in the range of 4~12mmWG.

[0192] In some embodiments the pressure drop across the body of material 6 is at least 0.2 mmWG per mm of axial length of the body of material 6, preferably at least 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 or 1.1 mmWG per mm of axial length of the body of material 6.

[0193] In some embodiments, the pressure drop in the body of material 6 is less than 2 mmWG per mm of axial length of the body of material 6, and preferably less than 1.6, 1.5, or 2 mmWG per millimeter of axial length of the body of material 6. 1.4, 1.3 or 1.2mmWG.

[0194] In some embodiments, the pressure drop across the body of material 6 is in the range of 0.3-1.5 mmWG per millimeter of axial length of the body of material 6, and preferably in the range of 0.4-1.2 mmWG per millimeter of axial length of the body of material 6.

[0195] In some embodiments the pressure drop across the body of material 6 is at least 2mmWG, preferably at least 3mmWG, preferably at least 4mmWG, at least 6mmWG, at least 8mmWG, at least 10mmWG or at least 11mmWG or at least 12mmWG or at least 15mmWG or at least 20mmWG or at least 23mmWG.

[0206] In some embodiments, the body of material 6 is a solid, cylindrical body of material.

[0207] In some embodiments, the mouthpiece 2 has a hardness in the range of about 80%-95%, preferably in the range of about 85%-90%. The hardness of the mouthpiece 2 is at least 80%, preferably at least 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, It may be 89%, 90%, 91% or 92%.

[0208] The hardness of the mouthpiece 2 may be measured according to the following protocol: When the hardness of a section is referred to herein, the hardness is measured by the following measurement steps: The measurement may be performed using any suitable device, such as a Borgwaldt HardnessTester H10.

[0209] Hardness is defined as the ratio of the height of a material body, h0, to the height of the material body under a given load, h1, and is expressed as a percentage of h0. Hardness is expressed as: Hardness = (h1 / h0)×100 In the case of individual bodies or bodies contained in rods consisting of several sections, the hardness measurement is carried out at a central point in the longitudinal direction of the body.

[0210] A defined load is applied to the material using a load bar. The length of the load bar must be significantly longer than the specimen to be measured. Prior to the hardness measurement, the material to be measured is conditioned according to ISO3402 for a minimum of 48 hours and is kept at the environmental conditions according to ISO3402 during the measurement.

[0211] To perform the hardness measurement, the material was placed in a Hardness Tester H10 and subjected to a preload of 2 g. is applied to the material and after 1 second the initial height h0 of the material under the 2g preload is recorded. The preload is then released and a load bar carrying a 150g load is lowered onto the sample at a rate of 0.6mm / s and after 5 seconds the height h1 of the material under the 150g load is measured.

[0212] The hardness of the mouthpiece is determined as the average hardness of at least 20 material bodies measured according to this protocol.

[0213] The hardness of the body of material 6 surrounded by the first plug wrapper 7 (hereinafter collectively referred to as the "member" for purposes of determining hardness) may be measured using the above protocol by carefully cutting the article to remove the body of material 6 surrounded by the first plug wrapper 7. The hardness of the member is at least 80%, preferably at least 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100%, 101%, 102%, 103%, 104%, 105%, 106%, 107%, 108%, 109%, 110%, 111%, 112%, 113%, 114%, 115%, 116%, 117%, 118%, 119%, 120%, 121%, 122%, 123%, 124%, 125%, 126%, 127%, 128%, 129%, 130%, 131%, 132%, 133%, 134%, 135%, 136%, 137%, 138%, 139%, 140%, 141%, 142%, 143%, 144%, 145%, 146%, 147%, 148%, 149%, 150%, 151%, 152%, 153%, 154%, 155%, 156%, 157%, 158%, 159%, 160%, 161%, 162%, 163%, 164%, 165%, 166%, 167%, 168%, 169%, 1 It may be 87%, 88%, 89%, 90%, 91% or 92%.

[0214] The expression "circularity" refers to the proportion of the cross-sectional shape of an article / part that coincides with a perfect circle. Circularity is calculated according to the following formula 1. (Formula 1) TIFF2025041931000002.tif10132

[0215] To determine the circularity of item 1, the maximum outer diameter "X" of the part is measured using a vernier caliper, and the minimum outer diameter "Y" of the item is measured using a vernier caliper (these diameters are perpendicular to the central axis of item 1). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of item 1, the higher the circularity, which indicates that the cross-sectional shape of item 1 is closer to being a perfect circle.

[0216] In some embodiments, the circularity of article 1 is at least 90%, preferably at least 91%, 92%, 93%, 94% or 95%.

[0217] The hardness of the body of material 6 surrounded by the first plug wrapper 7 (hereinafter collectively referred to as the "member" for purposes of determining roundness) may also be measured using the above protocol by carefully cutting the article to remove the body of material 6 surrounded by the first plug wrapper 7.

[0218] To determine the circularity of the body of material 6 (hereinafter collectively referred to as the "component" for purposes of determining circularity) surrounded by the first plug wrapper 7, the maximum outer diameter "X" of the component is measured using a vernier caliper, and the minimum outer diameter "Y" of the component is measured using a vernier caliper (these diameters are perpendicular to the central axis of the component). The smaller the deviation between the maximum outer diameter X and the minimum outer diameter Y of the component, the higher the circularity, which indicates that the cross-sectional shape of the component is closer to a perfect circle.

[0219] In some embodiments, the circularity of the part (ie, the circularity of the body of material 6 surrounded by the first plug wrapper 7) is at least 90%, preferably at least 91%, 92%, 93%, 94% or 95%.

[0220] High circularity of the article / component helps ensure that the downstream portion is processed reliably, otherwise it may become too oval and get jammed or not positioned accurately in the manufacturing machine.

[0221] Preferably, the length of tubular portion 4a is less than about 50 mm. More preferably, the length of tubular portion 4a is less than about 40 mm. Even more preferably, the length of tubular portion 4a is less than about 35 mm. Additionally or alternatively, the length of tubular portion 4a is preferably at least about 10 mm. Preferably, the length of tubular portion 4a is at least about 15 mm.

[0222] In some preferred embodiments, the length of the tubular portion 4a is about 15 mm to about 35 mm, more preferably about 20 mm to about 30 mm, even more preferably about 23 mm to about 27 mm, and most preferably about 25 mm. In this example, the length of the tubular portion 4a is 25 mm.

[0223] Preferably, the second plug wrapper 9 has a basis weight of less than 50 gsm, more preferably between about 20 gsm and 45 gsm. However, it should be recognized that the basis weight of the second plug wrapper 9 may be greater to provide a greater hardness to the mouthpiece. For example, the basis weight of the second plug wrapper 9 may be at least 50, 60, 70, 80, 90 or 100 gsm. In some embodiments, the basis weight of the second plug wrapper 9 is within the range of 50 to 110 gsm or within the range of 60 to 100 gsm.

[0224] In some embodiments, the second plug wrapper 9 has a basis weight of at least 10 gsm, or at least 15 gsm, or at least 20 gsm, or at least 25 gsm.

[0225] In some embodiments, the second plug wrapper 9 has a basis weight of less than 40, less than 35, or less than 30 gsm.

[0226] In some embodiments, the second plug wrapper 9 has a basis weight in the range of 10-40 gsm, preferably in the range of 15-35 gsm or in the range of 20-30 gsm or in the range of 25-30 gsm. In some embodiments, the basis weight of the second plug wrapper 9 is about 27 gsm.

[0227] Preferably, the second plug wrapper 9 has a thickness of between 30 μm and 60 μm, more preferably between 35 μm and 45 μm. However, it should be appreciated that the thickness of the second plug wrapper 9 may be increased to increase the hardness of the mouthpiece. In some embodiments, for example, the thickness of the second plug wrapper 9 may be at least 40, 50, 60, 70, 80, 90 or 100 microns. In some embodiments, the thickness of the second plug wrapper 9 is in the range of 40 to 120 microns or in the range of 50 to 100 microns.

[0228] The second plug wrapper 9 is preferably a non-porous plug wrapper having an air permeability of less than 100 Coresta units, such as less than 50 Coresta units. However, in alternative embodiments, the second plug wrapper 9 may be a porous plug wrapper, for example having an air permeability of greater than 200 Coresta units.

[0229] The tubular portion 4a is positioned around the mouthpiece 2 and defines a cavity within the mouthpiece, which acts as a cooling segment. The cavity provides a chamber through which heated volatiles generated by the aerosol-generating material 3 flow. The tubular portion 4a is hollow to provide a chamber for the deposition of the aerosol, yet is rigid enough to withstand axial compressive forces and bending movements that may occur during manufacture and while the article 1 is in use. The tubular portion 4a provides a physical transition between the aerosol-generating material 3 and the body of material 6. The physical transition through the tubular portion 4a provides a temperature gradient over the length of the tubular portion 4a.

[0230] Preferably, the mouthpiece 2 is 450 mm 3The mouthpiece 2 includes a cavity having an internal volume of at least this volume. It has been found that a good aerosol can be formed with a cavity of at least this volume. The size of the cavity allows sufficient space within the mouthpiece 2 to cool the heated volatile components which would otherwise result in an aerosol that is too warm, and thus the aerosol-generating material 3 would be exposed to higher temperatures. In this example the cavity is formed by the tubular portion 4a, but in alternative configurations the cavity could be formed within a different portion of the mouthpiece 2. More preferably the mouthpiece 2 has a cavity length of at least 500 mm, e.g. 3 More than 550mm, and even more preferably 3 The present invention further includes a cavity formed within the tubular portion 4a having an internal volume of about 550 mm to further improve aerosolization. 3 ~about 850mm 3 , preferably about 600 mm 3 ~ approx. 800mm 3 In this example, the internal cavity of the tubular portion 4a has a volume of about 762 mm 3 It has a volume of.

[0231] The tubular portion 4a may be configured to provide a temperature difference of at least 40° C. between the heated and volatilized components entering the first upstream end of the tubular portion 4a and the heated and volatilized components exiting the second downstream end of the tubular portion 4a. The tubular portion 4a is preferably configured to provide a temperature difference of at least 60° C., preferably at least 80° C. and more preferably at least 100° C. between the heated and volatilized components entering the first upstream end of the tubular portion 4a and the heated and volatilized components exiting the second downstream end of the tubular portion 4a. This temperature difference over the length of the tubular portion 4a protects the temperature sensitive body of material 6 from the high temperatures of the aerosol-generating material 3 when heated.

[0232] In another embodiment, the tubular portion 4a can be replaced by another cooling component, for example a component made from a body of material through which the aerosol passes longitudinally and which also performs the function of cooling the aerosol.

[0233] The mouthpiece 2 of the article 1 includes an upstream end 2a adjacent the aerosol-generating material 3 and a downstream end 2b distal to the aerosol-generating material.

[0234] The pressure drop or pressure differential (also referred to as resistance to drawing) across the mouthpiece, e.g., the portion of the article 1 downstream of the aerosol-generating material 3, is preferably less than about 40 mmH2O. Such a pressure drop has been found to allow sufficient aerosol, including flavor compounds, to be transferred through the mouthpiece 2 to the consumer. More preferably, the pressure drop across the mouthpiece 2 is less than about 20 mmH2O. In some embodiments, aerosol has been particularly improved by using a mouthpiece 2 having a pressure drop of less than 15 mmH2O, e.g., about 6 mmH2O, about 10 mmH2O or about 14 mmH2O. Alternatively or additionally, the pressure drop across the mouthpiece may be at least 3 mmH2O, preferably at least 4 mmH2O, more preferably at least 5 mmH2O. In some embodiments, the pressure drop across the mouthpiece may be between about 5 mmH2O and 20 mmH2O, preferably between 5 mmH2O and 15 mmH2O. These values ​​cause the mouthpiece 2 to decelerate the aerosol as it passes through the mouthpiece 2 so that the temperature of the aerosol has time to drop before it reaches the downstream end 2 b of the mouthpiece 2 .

[0235] In this example, the aerosol-generating material 3 is wrapped in a wrapper 10. The wrapper 10 may be, for example, The wrapper 10 may be a paper or paper-supported foil wrapper. In this example, the wrapper 10 is substantially air-impermeable. In another embodiment, the wrapper 10 preferably has an air permeability of less than 100 Coresta units, more preferably less than 60 Coresta units. It has been found that wrappers with low air permeability, for example less than 100 Coresta units, more preferably less than 60 Coresta units, result in improved formation of an aerosol at the aerosol-generating material 3. Without wishing to be bound by any theory, it is hypothesized that this is due to less loss of aerosol compounds through the wrapper 10. The air permeability of the wrapper 10 may be measured according to ISO 2965:2009 for measurement of air permeability of materials used as cigarette papers, filter plug wrappers and filter bonding papers.

[0236] In this embodiment, the wrapper 10 comprises an aluminum foil. Aluminum foil has been found to be particularly effective in enhancing the formation of aerosol within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer having a thickness of about 6 μm. In this example, the aluminum foil has a backing. However, in alternative configurations, the aluminum foil may have other thicknesses, for example, between 4 μm and 16 μm. The aluminum foil may also have no backing, for example formed from another material that helps provide the foil with adequate tensile strength. Metal layers or foils other than aluminum may also be used. The total thickness of the wrapper is preferably between 20 μm and 60 μm, more preferably between 30 μm and 50 μm, to provide the wrapper with suitable structural integrity and heat transfer properties. The tension that can be applied to the wrapper before it breaks is greater than 3,000 gram force, for example between 3,000 and 10,000 gram force or between 3,000 and 4,500 gram force.

[0237] In some cases, the wrapper 10 surrounding the aerosol-generating material 3 has a high level of air permeability, for example, greater than about 1000 Coresta units, or greater than about 1500 Coresta units, or greater than about 2000 Coresta units. The air permeability of the wrapper 10 can be measured in accordance with ISO 2965:2009 for measurement of air permeability of materials used as cigarette papers, filter plug wrappers and filter bonding papers.

[0238] The wrapper 10 may be formed from a material that has a high level of inherent air permeability, an inherently porous material, or may be formed from a material that has any level of inherent air permeability, where the final level of air permeability is achieved by providing the wrapper 10 with breathable sections or regions. Providing a breathable wrapper 10 provides a path for air to enter the article. The wrapper 10 may be breathable such that the amount of air entering through the rod of aerosol-generating material is relatively greater than the amount of air entering the article through the mouthpiece ventilation holes 12. Articles of this construction produce a more flavorful aerosol and result in greater user satisfaction.

[0239] In this example, the aerosol-forming material added to the aerosol-generating substrate 3 constitutes 14% by weight of the aerosol-generating substrate 3. Preferably, the aerosol-forming material constitutes at least 5% by weight of the aerosol-generating substrate 3, more preferably at least 10%. Preferably, the aerosol-forming material constitutes less than 25% by weight of the aerosol-generating substrate 3, more preferably less than 20%, for example 10% to 20%, 12% to 18% or 13% to 16%.

[0240] Preferably, the aerosol-generating material 3 is provided as a cylindrical rod of aerosol-generating material. Regardless of the shape of the aerosol-generating material, the aerosol-generating material 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 about 30 mm to 40 mm.

[0241] In some examples, article 1 may be configured to provide a separation (i.e., a minimum distance) between the heater and tubular portion 4a of non-combustion based aerosol delivery device 100 to prevent the heat of the heater from damaging the material forming tubular portion 4a.

[0242] The minimum distance between the heater and the tubular portion 4a of the non-combustion aerosol delivery device 100 may be 3 mm or more. In some examples, the minimum distance between the heater and the tubular portion 4a of the non-combustion aerosol delivery device 100 may be in the range of 3 mm to 10 mm, such as 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0243] The distance between the heater of the non-combustion aerosol delivery device 100 and the tubular portion 4a may be adjusted, for example, by adjusting the length of the rod of the aerosol-generating material 3.

[0244] The volume of the aerosol-generating material 3 to be installed is about 200 mm 3 ~ approx. 4300mm 3 , preferably about 500 mm 3 ~1500mm 3 , more preferably about 1000 mm 3 ~ approx. 1300mm 3 For example, the distance may vary by about 1000 mm. 3 ~ approx. 1300mm 3 Providing these volumes of aerosol-generating material has been shown to advantageously achieve superior aerosols with better visibility and perception performance than those achieved with volumes selected from the lower end of the range.

[0245] The mass of the aerosol-generating material 3 provided may be greater than 200 mg, for example between about 200 mg and 400 mg, preferably between about 230 mg and 360 mg, more preferably between about 250 mg and 360 mg. It has been found advantageous to provide a greater mass of aerosol-generating material, resulting in better sensory performance compared to aerosol generated from a lower mass of tobacco material.

[0246] Preferably, the aerosol-generating material or substrate is formed from a tobacco material as described herein that includes a tobacco component.

[0247] In the tobacco materials described herein, the tobacco components include reconstituted tobacco. The tobacco components include leaf tobacco, extruded tobacco and / or band-cast tobacco.

[0248] The aerosol-generating material 3 may include reconstituted tobacco material having a density of less than about 700 milligrams per cubic centimeter (mg / cc). Such tobacco materials have been found to be particularly useful in providing an aerosol-generating material that can be heated quickly to release an aerosol as compared to denser materials. For example, the inventors have tested the properties of various aerosol-generating materials, such as band-cast reconstituted tobacco material and paper reconstituted tobacco material, upon heating. For each given aerosol-generating material, during the application of heat to the material, there exists a particular zero heat flow temperature below which the net heat flow becomes endothermic, i.e., more heat enters the material than leaves it, and above which the net heat flow becomes exothermic, i.e., more heat leaves the material than enters it. Materials with densities less than 700 mg / cc have low zero heat flow temperatures. Since a significant portion of the heat flow leaving the material is via the formation of aerosol, having a low zero heat flow temperature has a beneficial effect on the time it takes to initially release an aerosol from the aerosol-generating material. For example, they found that aerosol-generating materials having a density less than 700 mg / cc had zero heat flow temperatures less than 164°C compared to materials having a density greater than 700 mg / cc that had zero heat flow temperatures greater than 164°C.

[0249] The density of the aerosol-generating material also affects the rate at which heat travels through the material; lower densities, e.g., less than 700 mg / cc, result in a slower rate of heat travel through the material, thus allowing for a more sustained aerosol release.

[0250] Preferably, the aerosol-generating material 3 comprises reconstituted tobacco material, such as paper reconstituted tobacco material, having a density of less than about 700 mg / cc. More preferably, the aerosol-generating material 3 comprises reconstituted tobacco material having a density of less than about 600 mg / cc. Alternatively or additionally, the aerosol-generating material 3 preferably comprises reconstituted tobacco material having a density of at least 350 mg / cc, which is believed to allow for a sufficient amount of heat transfer through the material.

[0251] The tobacco material may be provided in the form of shredded tobacco. The shredded tobacco has a cut width of at least 15 pieces per inch (5.9 pieces per centimeter, equivalent to a cut width of about 1.7 mm). Preferably, the shredded tobacco has a cut width of at least 18 pieces per inch (about 7.1 pieces per centimeter, equivalent to a cut width of about 1.4 mm), more preferably at least 20 pieces per inch (7.9 pieces per centimeter, equivalent to a cut width of about 1.27 mm). In one example, the shredded tobacco has a cut width of 22 pieces per inch (8.7 pieces per centimeter, equivalent to a cut width of about 1.15 mm). Preferably, the shredded tobacco has a cut width of at least 40 pieces per inch (about 15.7 pieces per centimeter, equivalent 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 result in a tobacco material that is favorable in terms of surface area to volume ratio and overall density and pressure drop of the generating material 3, particularly when heated. The shredded tobacco may be formed from a mixture of tobacco material forms, such as a mixture with 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.

[0252] In the tobacco materials described herein, the tobacco material may include a filler component. The filler component is generally a non-tobacco component, i.e., a component that does not contain tobacco-derived components. The filler component may be a non-tobacco fiber, such as wood fiber or pulp or wheat fiber. The filler component may be an inorganic material, such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, etc. The filler component may be a non-tobacco cast material or a non-tobacco extruded material. The filler component may be present in an amount of 0-20% by weight of the tobacco material or 1-10% by weight of the composition. In some embodiments, no filler component is included.

[0253] In the tobacco materials described herein, the tobacco material includes an aerosol-forming material. In this context, an "aerosol-forming material" is a chemical that facilitates the generation of an aerosol. The aerosol-forming material may facilitate the generation of an aerosol by facilitating the initial evaporation and / or condensation of a gas into an inhalable solid and / or liquid aerosol. In some embodiments, the aerosol-forming material may enhance the delivery of flavor from the aerosol-generating material. In general, any suitable aerosol-forming material or forming agent may be included in the aerosol-generating materials of the present disclosure, including those described herein. 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, non-polyols such as monohydric alcohols, high boiling point hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate or myristates 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, such as 13-16% by weight of the composition, or about 14% or 15% by weight of the composition. Propylene glycol, if included, may be present in an amount of 0.1-0.3% by weight of the composition.

[0254] The aerosol-forming material may be contained in any component, such as any component of the tobacco material and / or filler component, if any. Alternatively or additionally, the aerosol-forming material may be added separately to the tobacco material. In either case, the total amount of aerosol-forming material in the tobacco material may be as described herein.

[0255] The tobacco material may comprise 10-90% by weight of tobacco leaf, with the aerosol-forming material being provided in an amount of about 10% by weight of the tobacco leaf. It has been found to be advantageous to add this in a higher weight percentage to another component of the tobacco material, such as reconstituted tobacco material, to achieve a total amount of aerosol-forming material of 10%-20% by weight of the tobacco material.

[0256] The tobacco material described herein comprises nicotine, the nicotine content being between 0.5 and 1.75% by weight of the tobacco material, and may be, for example, between 0.8 and 1.5% by weight of the tobacco material. Additionally or alternatively, the tobacco material comprises 10-90% by weight of tobacco leaf having a nicotine content of more than 1.5% by weight of the tobacco leaf. It has been found advantageous to use tobacco leaf having a nicotine content of more than 1.5% in combination with a low nicotine base material, such as reconstituted tobacco, to obtain a tobacco material having an appropriate amount of nicotine but better sensory performance than reconstituted tobacco alone. Tobacco leaf, for example shredded tobacco, may have a nicotine content of, for example, 1.5% to 5% by weight of the tobacco leaf.

[0257] The tobacco material described herein may include an aerosol modifying agent, such as any of the flavorants described herein. In one embodiment, the tobacco material includes menthol to form a mentholated article. The tobacco material may include 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, and more preferably 8 mg to 16 mg of menthol. In this example, the tobacco material includes 16 mg of menthol. The tobacco material may include 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 includes 4.7% by weight of menthol. Such a high loading of menthol is achieved by using a high percentage of reconstituted tobacco material, for example more than 50% by weight of tobacco material. Alternatively or additionally, a high volume aerosol generating material, for example tobacco material, may be used to achieve a high aerosol generating capacity, for example about 500 mm 3 More than, or preferably 1000 mm 3Increasing menthol loading can be achieved when aerosol-generating materials such as tobacco materials are used.

[0258] For the avoidance of doubt, when amounts are given in weight percent in the compositions described herein, this means on a dry weight basis unless otherwise specified. Thus, any water present in the tobacco material or any component thereof is completely disregarded for purposes of measuring weight percent. The moisture content of the tobacco materials described herein may vary, for example, from 5 to 15 weight percent. The moisture content of the tobacco materials described herein may vary depending, for example, on the temperature, pressure and humidity conditions under which the compositions are maintained. The moisture content may be measured by Karl-Fisher analysis as known to those skilled in the art. However, for the avoidance of doubt, it is to be understood that the aerosol-forming material may be a glycerol-containing material. All components other than water are included in the weight of the tobacco material, even if they are components in the liquid phase, such as alcohol or propylene glycol. However, if an aerosol-forming material is provided in the tobacco component of the tobacco material or in the filler element (if any) of the tobacco material instead of or in addition to being added separately to the tobacco material, the aerosol-forming material is not included in the weight of the tobacco composition or filler element, but is included in the weight of the "aerosol-forming material" in the weight percentages specified herein. All other components present in the tobacco composition are included in the weight of the tobacco component, even if they are non-tobacco-derived (e.g., non-tobacco fibers in the case of reconstituted tobacco).

[0259] In some embodiments, the tobacco material comprises a tobacco component as defined herein and an aerosol forming material as defined herein. In some embodiments, the tobacco material consists essentially of a tobacco component as defined herein and an aerosol forming material as defined herein. In some embodiments, the tobacco material consists of a tobacco component as defined herein and an aerosol forming material as defined herein.

[0260] The reconstituted tobacco is present in the tobacco component of the tobacco material described herein in an amount between 10% and 100% by weight of the tobacco component. In some embodiments, the reconstituted tobacco is present in an amount between 10% and 80% or between 20% and 70% by weight of the tobacco component. In other embodiments, the tobacco component consists essentially of reconstituted tobacco or consists of reconstituted tobacco. In a preferred embodiment, the leaf tobacco is present in the tobacco component of the tobacco material in an amount of at least about 10% by weight of the tobacco component. For example, the leaf tobacco may be present in an amount of at least 10% by weight of the tobacco component, with the remainder of the tobacco component comprising a combination of reconstituted tobacco, band-cast tobacco or band-cast reconstituted tobacco and another form of tobacco, such as tobacco particles.

[0261] By reconstituted tobacco is meant tobacco material formed by a process in which raw tobacco material is extracted with a solvent to produce a residue containing soluble extract and fibrous material, and then the extract (usually after concentration, and optionally further processing) is recombined with the fibrous material from the residue (usually after removal of impurities from the fibrous material, and optionally with the addition of small amounts of non-tobacco fiber) by depositing the extract onto the fibrous material. The recombination process is similar to the papermaking process.

[0262] The reconstituted tobacco paper may be any type of reconstituted tobacco paper known in the art. In certain embodiments, the reconstituted tobacco paper is produced from a raw material comprising one or more of tobacco strips, tobacco stems, and whole tobacco leaves. In other embodiments, the reconstituted tobacco paper is produced from a raw material consisting of tobacco strips and / or whole tobacco leaves and tobacco stems. However, in other embodiments, waste, fines, and rice husk may be employed in the raw material alternatively or in addition thereto.

[0263] Reconstituted tobacco for use in the tobacco materials described herein may be prepared by methods known to those skilled in the art for the preparation of reconstituted tobacco.

[0264] In some embodiments, it is particularly advantageous to use a hollow tubular component 8 having a length of about 10 mm, e.g., about 10 mm to about 30 mm or about 12 mm to about 25 mm. It has been found that in some cases, a consumer's lips tend to extend up to about 12 mm from the mouth end of the article 1 when inhaling aerosol from the article 1, and thus a hollow tubular component 8 having a length of at least 10 mm or at least 12 mm will encircle most of the consumer's lips.

[0265] 3 is a side cross-sectional view of another article 1' that includes a mouthpiece 2' that includes a hollow tubular component 8. The mouthpiece 2' is substantially similar to the mouthpiece 2 described above, except that at the downstream end 2b, the mouthpiece 2' has a hollow tubular component 8 formed from filamentary tow. In this example, the tubular portion 4a, body of material 6 and hollow tubular component 8 are held together using a second plug wrapper 9 that is wrapped around all three sections.

[0266] The body of material 6 of the article 1' of Figure 3 is similar to the body of material 6 described above with reference to Figures 1 and 2. As before, the body of material 6 is manufactured from a sheet material comprising cellulose, for example the sheet material may be paper. The sheet material is pleated to form the body of material 6. The body of material 6 has a length of at least 115 mm. 3 has an outer volume of

[0267] In this example, the axial length L1 of the material 6 is about 10 mm. However, those skilled in the art will recognize that the material 6 may have a different axial length L1. Preferably, the length L1 of the material 6 is less than about 20 mm, preferably less than 15 mm. More preferably, the length L1 of the material 6 is less than about 10 mm. Additionally or alternatively, the length L1 of the material 6 is at least about 5 mm. Preferably, the length L1 of the material 6 is at least about 6 mm. In some preferred embodiments, the length L1 of the material 6 is about 5 mm to about 15 mm, more preferably about 6 mm to about 12 mm, even more preferably about 6 mm to about 10 mm, and most preferably about 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0268] The portion of the mouthpiece that contacts the consumer's lips typically comprises a paper tube surrounding a cylindrical body of hollow or filter material. It has been advantageously discovered that the provision of a hollow tubular component 8 significantly reduces the temperature of the exterior surface of the mouthpiece 2' at the downstream end 2b of the mouthpiece that contacts the consumer's mouth during use of the article 1'. It has also been advantageously discovered that the use of the tubular portion 4a also significantly reduces the temperature of the exterior surface of the mouthpiece 2', even at the upstream end of the tubular portion 4a. Without wishing to be bound by any theory, it is presumed that this is due to the tubular portion 4a directing the aerosol closer to the center of the mouthpiece 2', thus reducing the transfer of heat from the aerosol to the exterior surface of the mouthpiece 2'. It has also been found that the body of material 6 removes moisture from the aerosol generated by the aerosol-generating material 3 as the aerosol passes through the body of material 6A of the mouthpiece 2, causing the aerosol to feel cooler in the user's mouth.

[0269] In this example, the hollow tubular component 8 is formed from filamentary tow, although in alternative embodiments the hollow tubular component may be formed using any of the structures as described herein for the tubular portion 4a.

[0270] The "wall thickness" of the hollow tubular component 8 corresponds to the thickness of the wall of the tube 8 in the radial direction. This may be measured in the same way for the thickness of the wall of a tubular section. Advantageously, the wall thickness is greater than 0.9 mm, more preferably greater than or equal to 1.0 mm. Preferably, the wall thickness is substantially constant around the wall of the hollow tubular component 8. However, if the wall thickness is not substantially constant, the wall thickness is preferably greater than 0.9 mm, more preferably greater than or equal to 1.0 mm, anywhere around the circumference of the hollow tubular component 8.

[0271] Preferably, the length of the hollow tubular component 8 is less than about 20 mm. More preferably, the length of the hollow tubular component 8 is less than about 15 mm. Even more preferably, the length of the hollow tubular component 8 is less than about 10 mm. Additionally or alternatively, the length of the hollow tubular component 8 is at least about 5 mm. Preferably, the length of the hollow tubular component 8 is at least about 6 mm. In some preferred embodiments, the length of the hollow tubular component 8 is between about 5 mm and about 20 mm, more preferably between about 6 mm and about 10 mm, even more preferably between about 6 mm and about 8 mm, and most preferably about 6 mm, 7 mm, or about 8 mm. In this example, the length of the hollow tubular component 8 is 6 mm.

[0272] Preferably, the density of the hollow tubular component 8 is at least about 0.25 grams per cubic centimeter (g / cc), more preferably at least about 0.3 g / cc. Preferably, the density of the hollow tubular component 8 is at least about 0.75 grams per cubic centimeter. More preferably, the density of the hollow tubular component 8 is less than 0.6 g / cc, and more preferably less than 0.25 g / cc, more preferably 0.3 g / cc, more preferably 0.6 g / cc, or about 0.5 g / cc. These densities have been found to provide a good combination of good stiffness provided by high density materials and low thermal conductivity of low density materials. For purposes of the present invention, the "density" of the hollow tubular component 8 refers to the density of the filamentary tows forming the member, including any incorporated plasticizers. The density is determined by dividing the total weight of the materials forming the hollow tubular component 8 by the total volume of the hollow tubular component 8, which may be calculated using suitable measurements of the hollow tubular component 8, for example using a vernier caliper. If necessary, suitable dimensions may be measured using a microscope.

[0273] The filamentary tows forming the hollow tubular component 8 preferably have a total fineness of less than 45,000, more preferably less than 42,000. It has been found that this total fineness allows the formation of a hollow tubular component 8 that is not too dense. Preferably, the total fineness is at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filamentary tows forming the hollow tubular component 8 have a total fineness of 25,000 to 45,000, more preferably 35,000 to 45,000. Preferably, the cross-sectional shape of the filamentary tows is "Y" shaped, although in other embodiments other shapes such as "X" shaped filaments can be used.

[0274] The filamentary tows forming the hollow tubular component 8 preferably have a single yarn fineness greater than 3. It has been found that this single yarn fineness allows the formation of a hollow tubular component 8 that is not too dense. Preferably, the single yarn fineness is at least 4, more preferably at least 5. In a preferred embodiment, the filamentary tows forming the hollow tubular component 8 have a single yarn fineness between 4 and 10, more preferably between 4 and 9. In one example, the filamentary tows forming the hollow tubular component 8 are formed from cellulose acetate, e.g., 8Y40,000 tows containing 18% plasticizer, such as triacetin.

[0275] The hollow tubular component 8 preferably has an inner diameter greater than 3.0 mm. A smaller inner diameter would result in aerosol traveling through the mouthpiece 2' to the consumer's mouth at a faster than desired rate, which would cause the aerosol to become too warm, for example reaching temperatures of greater than 40° C. or 45° C. More preferably, the hollow tubular component 8 has an inner diameter greater than 3.1 mm, more preferably greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular component 8 is about 3.9 mm.

[0276] The hollow tubular component 8 preferably comprises 15% to 22% by weight of plasticizer. In the case of cellulose acetate tow, the plasticizer is preferably triacetin, but other plasticizers such as polyethylene glycol (PEG) can also be used. More preferably, the hollow tubular component 8 comprises 16% to 20% by weight of plasticizer, for example about 17%, about 18% or about 19% by weight of plasticizer.

[0277] In this example the tubular portion 4a is the first tubular component and the hollow tubular component 8 is the second hollow tubular component.

[0278] In this example ventilation is provided in the tubular portion 4a as described with reference to Figure 1. In alternative embodiments ventilation can be provided elsewhere in the mouthpiece, for example in the body of material 6 or in the hollow tubular component 8.

[0279] In the above example, the mouthpieces 2, 2' each comprise a single body of material 6. In other examples, the mouthpieces 2, 2' may comprise multiple bodies of material. The mouthpieces 2, 2' may comprise cavities between the bodies of material.

[0280] In some examples, the mouthpiece 2, 2' downstream of the aerosol-generating material 3 may include a wrapper, such as a first or second plug wrapper 7, 9 or tipping paper 5, which includes an aerosol modifier or other sensory material as described herein. The aerosol modifier may be disposed on an inwardly or outwardly facing surface of the mouthpiece wrapper. For example, the aerosol modifier or other sensory material may be provided in an area of ​​the wrapper, such as an outwardly facing surface of the tipping paper, that contacts the consumer's lips during use. By disposing the aerosol modifier or other sensory material on an outwardly facing surface of the mouthpiece wrapper, the aerosol modifier or other sensory material may be transferred to the consumer's lips during use. The aerosol modifier or other sensory material may be transferred to the consumer's lips during use of the article to modify the organoleptic properties (e.g., taste) of the aerosol generated by the aerosol-generating substrate or otherwise provide a different sensory experience to the consumer. For example, the aerosol modifier or other sensory material may impart a flavor to the aerosol generated by the aerosol-generating substrate 3. The aerosol modifier or other sensate may be at least partially soluble in water such that it is transferred to the user via the consumer's saliva. The aerosol modifier or other sensate may be volatilized by heat generated by the aerosol delivery system, which facilitates transfer of the aerosol modifier to the aerosol generated by the aerosol-generating substrate 3. Suitable sensates may be flavorants as described herein, cooling agents such as sucralose or menthol or the like. In other embodiments (not shown), the mouthpiece 2, 2' further or alternatively includes an aerosol modifier releasing member operable to selectively release the aerosol modifier.

[0281] 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 agent, a colorant, water, and a carbon adsorbent. The aerosol modifier may be, for example, a solid, liquid, or gel. The aerosol modifier may be a powder, string, or granule. The aerosol modifier may not include a filter material.

[0282] The aerosol modifier-releasing member may be, for example, a capsule, a thread or a bead. In some embodiments, multiple aerosol modifier-releasing members are provided and may comprise multiple charcoal particles loaded with the aerosol modifier.

[0283] In some embodiments, the aerosol modifier releasing component comprises a thread loaded with the additive. The thread may be made from fibers made of cellulose acetate or cotton.

[0284] In some embodiments, the aerosol modifier releasing component has in the range of 1 mg to 20 mg of aerosol modifier, preferably in the range of 2 mg to 15 mg of aerosol modifier.

[0285] The aerosol modifier-releasing members may, for example, be capsules located within the body of material 6. The or each aerosol modifier-releasing member may be associated with the sheet of material 6A, for example adhered to the sheet of material 6A before the sheet of material 6A is formed into the body of material 6.

[0286] In some embodiments, a non-combustion based aerosol delivery system is provided that includes an aerosol modifier releasing member and a heater that is operable, in use, to heat the aerosol-generating material 3 to cause the aerosol-generating material to generate an aerosol.

[0287] The aerosol modifier-releasing component may comprise a capsule. In some embodiments, the aerosol modifier-releasing component comprises a first and a second capsule. The first capsule is disposed in a first portion of the aerosol modifier-releasing component and the second capsule is disposed in a second portion of the aerosol modifier-releasing component downstream from the first portion.

[0288] A first portion of the aerosol modifier-releasing component is heated to a first temperature during operation of the heater to generate an aerosol, and a second portion is heated to a second temperature during operation of the heater to generate an aerosol, the second temperature being at least 4° C. lower than the first temperature. Preferably, the second temperature is at least 5, 6, 7, 8, 9 or 10° C. lower than the first temperature.

[0289] The aerosol modifier-releasing member may comprise at least one or more components of the article 1. In some embodiments the first and second capsules are disposed in a body of material 6. In one embodiment the aerosol modifier-releasing member comprises two bodies of material (not shown), the first capsule being disposed in the first body of material and the second capsule being disposed in the second body of material. In some embodiments the aerosol modifier-releasing member alternatively or in addition comprises one or more tubular components upstream and / or downstream of the one or more bodies of material. The aerosol-generating component may comprise a mouthpiece 2, 2'.

[0290] In some embodiments, the second capsule is at least 7 mm away from the first capsule, measured as the distance between the first and second capsules. Preferably, the second capsule is at least 8, 9 or 10 mm away from the first capsule. It has been found that increasing the distance between the first and second capsules increases the difference between the first and second temperatures.

[0291] The first capsule contains an aerosol modifier, and the second capsule contains an aerosol modifier that is the same or different from the aerosol modifier in the first capsule, and in some embodiments, a user may selectively rupture the first and second capsules by applying an external force to the aerosol modifier releasing member to release the aerosol modifier from each capsule.

[0292] The aerosol modifier in the second capsule is heated to a lower temperature than the aerosol modifier in the first capsule due to the difference between the first and second temperatures.

[0293] The aerosol modifiers of the first and second capsules can be selected based on this temperature difference. For example, the first capsule contains a first aerosol modifier that has a lower vapor pressure than the aerosol modifier of the second capsule. If both capsules are heated to the same temperature, the higher vapor pressure of the second aerosol modifier means that more of the second aerosol modifier will volatilize relative to the aerosol modifier of the first capsule. However, since the second capsule is heated to a lower temperature, this effect is less noticeable as a more uniform amount of the aerosol modifier of the first and second capsules volatilizes upon breaking the first and second capsules, respectively.

[0294] In some embodiments, the first and second capsules have the same aerosol modification type, meaning that both capsules contain the same type of aerosol modifying agent in the same amount, and if both capsules are heated to the same temperature and broken, both capsules will modify the aerosol in the same way. However, since the first capsule is heated to a higher temperature than the second capsule, the aerosol modifying agent in the first capsule will volatilize more compared to the agent in the second capsule, and will modify the aerosol more significantly than the second capsule. Thus, despite the fact that both capsules are the same, which allows the aerosol modifying agent releasing member to be manufactured more easily and / or less expensively, the user can decide whether to break the first capsule, which modifies the aerosol more significantly, or the second capsule, which modifies the aerosol less, or to break both capsules to modify the aerosol more significantly.

[0295] In some embodiments, the first and second capsules both contain a first and a second aerosol modifier. The first modifier has a lower vapor pressure than the second aerosol modifier. Thus, when the second capsule is broken, a greater proportion of the second aerosol modifier evaporates relative to the first aerosol modifier when the system is in use to generate an aerosol, compared to when the hotter first capsule is broken. Thus, the same capsule can be used to generate aerosols with different modifications based on the position of the capsule in the first or second portion of the aerosol modifier releasing member.

[0296] In some embodiments, the or each capsule comprises an outer shell and an inner core.

[0297] The shell of each capsule is solid at room temperature. The shell comprises, consists of, or consists 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 comprise, consist of, or consist essentially of gelatin, carrageenan, or pectin. The shell may comprise, consist of, or consist essentially of one or more of alginate, gelatin, carrageenan, or pectin.

[0298] The shell of each additive capsule may be impermeable or substantially impermeable to the aerosol modifier in the core, such that the shell initially prevents the core modifier from escaping the capsule, and when a user desires to modify the aerosol, the capsule shell is crushed to release the modifier.

[0299] In some embodiments (not shown), the or each capsule further comprises a carrier material, which may, for example, comprise gelatin.

[0300] In some embodiments, the or each capsule has a diameter in the range of 1 to 5 mm, preferably in the range of 2 to 4 mm. In some embodiments, the or each capsule has a diameter of about 3 mm. The or each capsule may be approximately spherical. In other examples, capsules of other shapes and sizes may be used.

[0301] The total weight of each capsule may be in the range of about 5 mg to about 50 mg, preferably in the range of about 10 to 30 mg, In some embodiments, each capsule has a weight of about 14 mg.

[0302] In some embodiments, the one or more aerosol modifier-releasing members are contained within the body of material 6, and the body of material 6 is formed from a sheet material having a basis weight of less than 40 gsm, preferably less than 35 or 30 gsm. This serves to reduce the density of the body of material 6 to offset the presence of the aerosol modifier-releasing members within the body of material 6 which results in an increase in the stiffness of the body of material 6.

[0303] In some embodiments one or more aerosol modifier-releasing members are contained within the body of material 6, which is formed from a sheet material having a width of less than 100mm, preferably less than 90 or 80mm. This serves to reduce the density of the body of material 6 to offset the presence of the aerosol modifier-releasing members within the body of material 6 which results in an increase in the stiffness of the body of material 6.

[0304] In some embodiments the or each capsule is centred on the longitudinal axis of the mouthpiece 2 .

[0305] As noted above, each capsule has a core-shell structure, i.e., the encapsulating or barrier material forms a shell around a core containing the aerosol modifier. The shell structure prevents migration of the aerosol modifier during storage of the article, but allows for controlled release of the aerosol modifier, also referred to as the aerosol modifier, during use.

[0306] In some cases, the barrier material (also referred to as an encapsulant) is frangible. The or each capsule may be crushed or otherwise broken or destroyed by the user to release the encapsulated aerosol modifier. Typically, one of the capsules is broken just before heating is initiated, but the user may choose when to release the aerosol modifier in that capsule. The user may then later, for example after heating has been initiated, to release the aerosol modifier. A user may choose to break the other capsule once a portion of the aerosol has been released from the aerosol-generating material, such that the remaining aerosol-generating material is modified by the aerosol modifying agent in the other capsule. Alternatively, a user may choose to break multiple capsules simultaneously.

[0307] The term "frangible capsule" means a capsule whose shell can be broken by pressure to release the core, e.g. the shell can be burst by pressure applied by a user's finger when the user wishes to release the capsule's core.

[0308] In some cases, the barrier material is heat resistant, i.e., in some cases, the barrier does not rupture but melts or fails at temperatures reached by the capsule during operation of the aerosol delivery device. In particular, the capsule located within the mouthpiece may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material may continue to retain the liquid core up to at least about 50°C to 120°C.

[0309] In another example, the or each capsule releases the core composition upon heating, for example by swelling of the capsule melting the barrier material or rupturing the barrier material.

[0310] The total weight of each capsule may be in the range of about 1 mg to about 100 mg, preferably about 5 mg to about 60 mg, about 8 mg to about 50 mg, about 10 mg to about 20 mg, or about 12 mg to about 18 mg.

[0311] The total weight of the core formulation may be in the range of about 2 mg to about 90 mg, preferably about 3 mg to about 70 mg, about 5 mg to about 25 mg, about 8 mg to about 20 mg, or about 10 mg to about 15 mg.

[0312] In some embodiments, the or each capsule comprises a core as described above and a shell. The capsules may each exhibit a crushing strength of about 4.5N to about 40N, more preferably about 5N to about 30N or about 28N (e.g., about 9.8N to about 24.5N). Capsule crush strength can be measured using a gauge which measures the force at which the capsule bursts when it is removed from the body of material 6 and pressed between two flat metal plates. A suitable measuring device is a Sauter FK 50 force gauge which has a flat-headed attachment which can be used to crush the capsule against a flat hard surface with a similar surface to the attachment.

[0313] The capsules may be substantially spherical and have a diameter of at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm, or 3.0 mm. The or each capsule may have a diameter of less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5 mm, 5.0 mm, 4.5 mm, 4.0 mm, 3.5 mm or 3.2 mm. Specifically, the capsule may have a diameter of from about 0.4 mm to about 10.0 mm. 2.0 mm, about 0.8 mm to about 6.0 mm, about 2.5 mm to about 5.5 mm, or about 2.8 mm to about 3.2 mm. In some cases, each capsule has a diameter of about 3.0 mm. These dimensions are particularly suitable for incorporating the capsules into the articles described herein.

[0314] The cross-sectional area of ​​each capsule at its largest cross-sectional area is in some embodiments less than 28%, more preferably less than 27%, and even more preferably less than 25% of the cross-sectional area of ​​the portion of mouthpiece 2 in which the capsule is located. For example, for a spherical capsule having a diameter of 3.0 mm, the maximum cross-sectional area of ​​the capsule is less than 7.07 mm 2 In the case of a mouthpiece having a circumference of 21 mm as described above, the outer circumference of the material body 6 is 20.8 mm, and the radius of this member is 3.31 mm, which is 34.43 mm. 2 In this example, the cross-sectional area of ​​the capsule is 20.5% of the cross-sectional area of ​​the mouthpiece 2. As another example, if the capsule has a diameter of 3.2 mm, its maximum cross-sectional area is 8.04 mm 2 In this case, the cross-sectional area of ​​the capsule is 23.4% of the cross-sectional area of ​​the body of material 6. A capsule having a maximum cross-sectional area of ​​less than 28% of the cross-sectional area of ​​the portion of the mouthpiece 2 in which the capsule is provided has the advantage that the pressure drop across the mouthpiece 2 is reduced compared to a capsule having a larger cross-sectional area, and adequate space remains around the capsule for the aerosol to pass through without the body of material 6 removing significant amounts of bulk aerosol as it passes through the mouthpiece 2. In some embodiments, first and second capsules are provided and may be of the same size or different sizes.

[0315] FIG. 4 is a cross-sectional side view of another article 1'' including a mouthpiece 2''. The mouthpiece 2'' is substantially similar to the mouthpiece 2 described above with reference to FIGS. 1 and 2. The difference is that the body of material 6 of the article 1' is located upstream of the tubular portion 4a.

[0316] In this example, the tubular portion 4a and the body of material 6 are held together using a second plug wrapper 9 which is wrapped around both sections.

[0317] The body of material 6 of article 1'' in Figure 4 is similar to the body of material 6 described above with reference to Figures 1 to 3. As before, the body of material 6 is manufactured from a sheet material which comprises cellulose, for example the sheet material may be paper. The sheet material is pleated to form the body of material 6.

[0318] The body of material 6 is located at the upstream end 2a of the mouthpiece 2'. The body of material 6 is adjacent to the aerosol-generating material 3.

[0319] The tubular portion 4a is arranged at the downstream end 2b of the mouthpiece 2'' and forms a carrier 4c at the downstream end. The tubular portion 4a is located downstream of the body of material 6. In this example, the tubular portion 4a is adjacent to the body of material 6.

[0320] The tubular portion 4a has an axial length L2 of at least 20 mm, preferably at least 22 mm. In this example, the axial length L2 of the tubular portion 4a is about 25 mm.

[0321] It has been found that a tube with an axial length L2 of at least 20mm results in significant cooling of the aerosol as it passes through the tubular portion 4a. Furthermore, as mentioned above, the cellulose-containing sheet material of the body of material 6 absorbs water from the aerosol. Removing moisture from the aerosol makes the aerosol feel cooler in the user's mouth.

[0322] In some embodiments, the tubular portion 4a includes one or more ventilation holes, which also contribute to cooling the aerosol.

[0323] In some embodiments, the tubular portion 4a is made from paper.

[0324] FIG. 5 is a cross-sectional side view of yet another article 1''' that includes a mouthpiece 2'''. The mouthpiece 2''' is substantially similar to the mouthpiece 2 described above with reference to FIGS. 1 and 2. The difference is that the mouthpiece 2''' further includes a tubular component 20 within the body of material 6.

[0325] In this example, the tubular portion 4a and the body of material 6 are held together using a second plug wrapper 9 which is wrapped around both sections.

[0326] The body of material 6 of article 1''' in Figure 5 is similar to the body of material 6 described above with reference to Figures 1 to 3. As before, the body of material 6 is manufactured from a sheet material which comprises cellulose, for example the sheet material may be paper. The sheet material is pleated to form the body of material 6.

[0327] The tubular component 20 may be, for example, a paper tube disposed within the body of material 6. The tubular component 20 may form a cavity 21 within the body of material 6. Optionally, the tubular component 20 is substantially radially centrally located within the body of material 6.

[0328] In this example the cavity 21 extends to the downstream end 2b of the mouthpiece 2'''.

[0329] In this example, the axial length L1 of the material 6 is about 10 mm. However, those skilled in the art will recognize that the material 6 may have a different axial length L1. Preferably, the length L1 of the material 6 is less than about 15 mm. More preferably, the length L1 of the material 6 is less than about 10 mm. Additionally or alternatively, the length L1 of the material 6 is at least about 5 mm. Preferably, the length L1 of the material 6 is at least about 6 mm. In some preferred embodiments, the length L1 of the material 6 is about 5 mm to about 15 mm, more preferably about 6 mm to about 12 mm, even more preferably about 6 mm to about 10 mm, and most preferably about 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0330] In some embodiments, the tubular component 20 has an axial length of at least 4 mm, and preferably a length of about 5 mm.

[0331] The cavity 21 has been found to facilitate cooling of the aerosol. The portion 6B of the body of material 6 surrounding the tubular component 20 has been found to effectively insulate the user's lips from the heat of the aerosol. For example, in embodiments in which the body of material 6 is fabricated from a sheet material disposed within the body of material, it is believed that the multiple layers of the sheet material comprising the body of material 6 help insulate the user's lips from the heat of the aerosol. In some embodiments, there may optionally be gaps, e.g., air gaps, between the layers of the sheet material that contribute to the insulating effect.

[0332] The body of material 6 may also be more easily biodegradable than if a cellulose acetate tubular portion 8 were instead provided at the downstream end 2b of the mouthpiece.

[0333] The body of material 6 may be manufactured from multiple lengths of rod 22, in this example four lengths of rod, as shown in Figure 6. The rod is cut at lines CC to form individual bodies of material 6 each including a tubular component 20 with a corresponding cavity 21.

[0334] A non-combustion aerosol delivery device is used to heat the articles 1, 1', 1'', 1''' described herein. The non-combustion aerosol delivery device preferably includes a coil, which has been found to provide better heat transfer to the articles 1, 1', 1'', 1''' compared to other configurations.

[0335] In some examples, the coil is configured, when in use, to heat at least one conductive heating element such that thermal energy can be conducted from the at least one conductive heating element to the aerosol-generating material, thereby causing heating of the aerosol-generating material.

[0336] In some examples, the coil is configured to generate a varying magnetic field for passage through at least one heating element, in use, thereby causing inductive heating and / or magnetic hysteresis heating of the at least one heating element. In such a configuration, the or each heating element may be referred to as a "susceptor" as defined herein. A coil configured to generate a varying magnetic field for passage through an electrically conductive heating element, in use, thereby causing inductive heating of the at least one electrically conductive heating element, may be referred to as an "induction coil" or "inductor coil."

[0337] The device may include one or more heating elements, e.g. one or more conductive heating elements, which may be suitably positioned or positionable relative to the coil to allow heating of the one or more heating elements. The one or more heating elements may be fixed relative to the coil. At least one heating element, e.g. at least one conductive heating element, may be included in the article 1, 1', 1'', 1''', for insertion into a heating region of the device, the article 1, 1', 1'', 1''', including the aerosol-generating material 3, and removed from the heating region after use. Alternatively, the device and such article 1, 1', 1'', 1''', may include at least one respective heating element, e.g. at least one conductive heating element, and the coil causes heating of the one or more heating elements of the device and article, respectively, when the article is in the heating region.

[0338] In some cases, the coil is helical. In some cases, the coil surrounds at least a portion of a heating region of a device configured to contain the aerosol generating material. In some cases, the coil is a helical coil that surrounds at least a portion of a heating region.

[0339] In some cases, the device includes an electrically conductive heating element at least partially surrounding the heating region, and the coil surrounds at least a portion of the electrically conductive heating element. In some cases, the electrically conductive heating element is tubular. In some cases, the coil is an inductor coil.

[0340] In some cases, the use of a coil allows a non-combustion based aerosol delivery device to reach an operating temperature more quickly than a non-coil aerosol delivery device. For example, a non-combustion based aerosol delivery device including a coil as described above can reach an operating temperature such that a first puff can be provided in less than 30 seconds, preferably less than 25 seconds, from initiation of the device heating program. In some cases, the device can reach an operating temperature in about 20 seconds from initiation of the device heating program.

[0341] The use of a coil as described herein in a device to induce heating of the aerosol-generating material has been found to improve the aerosol generated. For example, consumers have reported that aerosols generated by devices including coils such as those described herein feel closer to factory made cigarettes (FMC) than aerosols produced by other non-combustion based aerosol delivery systems. Without wishing to be bound by any theory, it is hypothesized that this is due to the reduced time to reach the required heating temperature when using a coil, the higher heating temperature achieved when using a coil, and / or the coil allowing such systems to simultaneously heat a relatively large amount of aerosol-generating material, resulting in an aerosol with a temperature similar to that of FMC. In FMC products, a burning ember generates a hot aerosol that heats the tobacco in the tobacco rod behind the ember as the aerosol is drawn through the rod. It is understood that this hot aerosol releases flavor compounds from the tobacco in the rod behind the burning ember. It is believed that devices including coils as described herein can also heat aerosol-generating materials, such as tobacco materials as described herein, to release flavor compounds, resulting in aerosols that have been reported to be more similar to FMC aerosols. Particular improvements in aerosols are achieved by using devices including coils to heat articles that include rods of aerosol-generating material having a circumference of greater than 19 mm, e.g., between about 19 mm and 23 mm.

[0342] By using an aerosol delivery system including a coil as described herein, e.g., an induction coil that heats at least a portion of the aerosol-generating material to at least 200° C., more preferably at least 220° C., an aerosol can be generated from the aerosol-generating material having certain characteristics believed to be more similar to the aerosols of FMC products. For example, when an aerosol-generating material containing nicotine is heated using an induction heater to at least 250° C. under an air flow of at least 1.50 L / m for 2 seconds, one or more of the following characteristics have been observed: At least 10 μg of nicotine is aerosolized from the aerosol generating material; The weight ratio of aerosol forming material to nicotine in the generated aerosol is at least about 2.5:1, preferably at least 8.5:1; At least 100 μg of the aerosol-forming material can be aerosolized from the aerosol-generating material; The average particle or droplet size in the generated aerosol is less than about 1000 nm; The aerosol density is at least 0.1 μg / cc.

[0343] Optionally, at least 10 μg of nicotine, preferably at least 30 μg or 40 μg of nicotine, is aerosolized from the aerosol-generating material during that 2 second period under an airflow of at least 1.50 L / m. Optionally, less than about 200 μg of nicotine, preferably less than about 150 μg or less than about 125 μg of nicotine, is aerosolized from the aerosol-generating material during that 2 second period under an airflow of at least 1.50 L / m.

[0344] Optionally, at least 100 μg of aerosol forming material, preferably at least 200 μg, 500 μg or 1 mg of aerosol forming material is aerosolized from said aerosol generating material under an airflow of at least 1.50 L / m during said 2 second period. Preferably, the aerosol forming material comprises or consists of glycerol.

[0345] As defined herein, the term "average particle or droplet size" refers to the average size of the solid or liquid components of the aerosol (i.e., the components that are suspended in the gas). When the aerosol contains suspended liquid droplets and suspended solid particles, the term refers to the average size of all components combined.

[0346] In some cases, the average particle or droplet size of the generated aerosol may be less than 900 nm, 800 nm, 700 nm, 600 nm, 500 nm, 450 nm, or 400 nm. In some cases, the average particle or droplet size may be greater than about 25 nm, 50 nm, or 100 nm.

[0347] In some cases, the density of the aerosol generated during the period may be at least 0.1 μg / cc. In some cases, the aerosol density is at least 0.2 μg / cc, 0.3 μg / cc, or 0.4 μg / cc. In some cases, the aerosol density is less than about 2.5 μg / cc, 2.0 μg / cc, 1.5 μg / cc, or 1.0 μg / cc.

[0348] The non-combustion aerosol delivery device is configured to heat the aerosol-generating material 3 of the article 1, 1', 1'', 1''', preferably to a maximum temperature of at least 160° C. Preferably, the non-combustion aerosol delivery device is configured to heat the aerosol-forming material 3 of the article 1, 1', 1'', 1''' to a maximum temperature of at least about 200° C., or at least about 220° C. or at least about 240° C., more preferably at least about 270° C., at least once during the heating step with the non-combustion aerosol delivery device.

[0349] By using an aerosol delivery system including a coil as described herein, such as an induction coil that heats at least a portion of the aerosol-generating material to at least 200°C, more preferably at least 220°C, a higher temperature aerosol can be generated from the aerosol-generating material of article 1 described herein than previous devices that contribute to generating an aerosol that is believed to be closer to an FMC product as the aerosol exits the mouth end of mouthpiece 2.

[0350] In some embodiments, the temperature of the aerosol leaving the mouth end of the mouthpiece 2, 2', 2'', 2''' is below 50°C, preferably below 45°C.

[0351] FIG. 7 shows an example of a non-combustion based aerosol delivery device 100 for generating an aerosol from an aerosol-generating medium / material, such as the aerosol-generating material 3 of the articles 1, 1', 1'', 1''' described herein. In general terms, the device 100 may be used to heat a replaceable article 110 that contains an aerosol-generating medium, such as the articles 1, 1', 1'', 1''' described herein, to generate an aerosol or other inhalable medium that is inhaled by a user of the device 100. The device 100 and the replaceable article 110 together form a system.

[0352] The device 100 includes a housing 102 (in the form of an outer cover) that surrounds and contains the various components of the device 100. The device 100 has an opening 104 at one end through which an item 110 is inserted for heating by a heating assembly. In use, the item 110 is fully or partially inserted into the heating assembly where it is heated by one or more components of the heating assembly.

[0353] When article 110 is inserted into device 100, the minimum distance between one or more members of the heating assembly and tubular portion 4a of article 110 may be in the range of 3 mm to 10 mm, for example 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm.

[0354] The device 100 in this example includes a first end member 106, which includes a lid 108 that is movable relative to the first end member 106 to close the opening 104 when the item 110 is not in place. Although the lid 108 is shown in an open configuration in Figure 8, the lid 108 may be moved to a closed configuration. For example, a user may slide the lid 108 in the direction of arrow "B."

[0355] The device 100 may include a user-operable adjustment member 112, such as a button or switch that, when pressed, activates the device 100. For example, a user may operate the switch 112 to power the device 100 on.

[0356] Device 100 also includes electrical components such as a socket / port 114, which may accommodate a cable for charging a battery in device 100. Socket 114 may be a charging port, such as a USB charging port.

[0357] Figure 8 shows the device 100 of Figure 7 without the outer cover 102 and without the presence of the item 110. The device 100 defines a longitudinal axis 134.

[0358] 8, the first end member 106 is disposed at one end of the device 100 and the second end member 116 is disposed at the opposite end of the device 100. The first and second end members 106, 116 together at least partially define an end surface of the device 100. For example, the bottom surface of the second end member 116 at least partially defines the bottom surface of the device 100. An edge of the outer cover 102 also defines a portion of the end surface. In this example, the lid 108 also defines a portion of the top surface of the device 100.

[0359] The end of the device nearest the opening 104 is also known as the proximal end (or mouth end) of the device 100 because it is closest to the user's mouth during use. In use, a user inserts an article 110 into the opening 104, operates a user control to initiate heating of the aerosol-generating material, and inhales the aerosol generated by the device, thereby causing the aerosol to flow within the device 100 along a flow path toward the proximal end of the device 100.

[0360] The other end of the apparatus away from opening 104 is also known as the distal end of device 100, as this is the end that will be away from the user's mouth during use. When a user inhales the aerosol generated by the device, the aerosol flows away from the distal end of device 100.

[0361] The device 100 further includes a power source 118. The power source 118 may be a battery, such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include lithium batteries (such as lithium ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically connected to the heating assembly and provides power as needed and under the control of a controller (not shown) to heat the aerosol generating material. In this example, the battery is connected to a central support 120 that holds the battery 118 in place.

[0362] The device further includes at least one electronic module 122. The electronic module 122 may include, for example, a printed circuit board (PCB). The PCB 122 may support a controller, such as at least one processor and memory. The PCB 122 may also include one or more electrical tracks that electrically connect together various electronic components of the device 100. For example, battery terminals may be electrically connected to the PCB 122 so that power can be distributed throughout the device 100. The socket 114 may also be electrically coupled to a battery via the electrical tracks.

[0363] In the example of device 100, the heating assembly is an induction heating assembly, which includes various components for heating the aerosol-generating material of the article 110 via an induction heating process. Induction heating is a process of heating an electrically conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may include an induction member, for example one or more inductor coils, and a device for passing a varying current, such as an alternating current, through the induction member. The varying current in the induction member generates a varying magnetic field. The varying magnetic field penetrates a susceptor, which is preferably positioned relative to the induction member, and generates eddy currents inside the susceptor. The susceptor has an electrical resistance to the eddy currents, and therefore the flow of eddy currents against this resistance causes the susceptor to heat by Joule heating. If the susceptor includes a ferromagnetic material, such as iron, nickel, or cobalt, heat may be generated by magnetic hysteresis losses in the susceptor, i.e., by a change in orientation of the magnetic dipoles of the magnetic material as a result of matching the varying magnetic field. Inductive heating allows for faster heating than, for example, conductive heating, since heat is generated inside the susceptor. Furthermore, no physical contact is required between the dielectric heater and the susceptor, allowing greater flexibility in design and application.

[0364] The induction heating assembly of the example device 100 includes a susceptor structure 132 (hereinafter "susceptor"), a first inductor coil 124, and a second inductor coil 126. The first and second inductor coils 124, 126 are made from a conductive material. In this example, the first and second inductor coils 124, 126 are made from a Litz wire / cable that is wound in a helical shape to provide a helical inductor coil 124, 126. The Litz wire includes multiple individual wires that are individually insulated and twisted together to form a single wire. The Litz wire is designed to reduce skin effect losses in the conductor. In the example device 100, the first and second inductor coils 124, 126 are made from copper Litz wire with a rectangular cross section. In other examples, the Litz wire may have other cross sections, such as circular.

[0365] The first inductor coil 124 is configured to generate a first varying magnetic field for heating a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second varying magnetic field for heating a second section of the susceptor 132. In this example, the first inductor coil 124 is adjacent to the second inductor coil 126 in a direction along a longitudinal axis 134 of the device 100 (i.e., the first and second inductor coils 124, 126 do not overlap). The susceptor structure 132 may include a single susceptor or two or more susceptors. Ends 130 of the first and second inductor coils 124, 126 are connected to the PCB 122.

[0366] Of course, in some examples, the first and second inductor coils 124, 126 may have at least one different characteristic. For example, the first inductor coil 124 may have at least one different characteristic from the second inductor coil 126. For example, in one example, the first inductor coil 124 may have a different inductance value than the second inductor coil 126. In FIG. 8, the first and second inductor coils 124, 126 are different lengths such that the first inductor coil 124 is wound on a smaller section of the susceptor 132 than the second inductor coil 126. Thus, the first inductor coil 124 may have a different number of turns than the second inductor coil 126 (assuming the spacing between the individual turns is substantially the same). In yet another example, the first inductor coil 124 may be made of a different material than the second inductor coil 126. In some examples, the first and second inductor coils 124, 126 may be substantially the same.

[0367] In this example, the first and second inductor coils 124, 126 are shown wound in opposite directions. This is useful when the inductor coils are active at different times. For example, the first inductor coil 124 may be activated first to heat a first section / portion of the article 110, and then the second inductor coil 126 may be activated to heat a second section / portion of the article 110. Winding the coils in different directions helps reduce the current induced in the inductor coils when used with certain types of control circuits. In FIG. 8, the first inductor coil 124 is a right-handed spiral and the second inductor coil 126 is a left-handed spiral. However, in other embodiments, the inductor coils 124, 126 may be wound in the same direction, or the first inductor coil 124 may be a left-handed spiral and the second inductor coil 126 may be a right-handed spiral.

[0368] The susceptor 132 in this example is hollow and thus defines a receptacle in which the aerosol-generating material is received. For example, the article 110 is inserted into the susceptor 132. In this example, the susceptor 132 is tubular and has a circular cross-section.

[0369] The susceptor 132 may be made from one or more materials. Preferably, the susceptor 132 comprises carbon steel with a coating of nickel or cobalt.

[0370] In some examples, the susceptor 132 may include at least two materials that can be heated at two different frequencies for selective aerosolization of the at least two materials. For example, a first section of the susceptor 132 (heated by the first inductor coil 124) may include a first material, and a second section of the susceptor 132 (heated by the second inductor coil 126) may include a different second material. In another example, the first section may include a first and a second material, and the first and second materials may be heated separately based on the activation of the first inductor coil 124. The first and second materials may be adjacent along an axis defined by the susceptor 132 or may form different layers within the susceptor 132. Similarly, the second section may include a third and a fourth material, and the third and fourth materials may be heated separately based on the activation of the second inductor coil 126. The third and fourth materials may be adjacent along an axis defined by the susceptor 132, or may form different layers within the susceptor 132. For example, the third material may be the same as the first material and the fourth material may be the same as the second material. Alternatively, each of these materials may be different. The susceptor may include, for example, carbon steel or aluminum.

[0371] 8 further includes an insulating member 128 that is generally tubular and at least partially surrounds the susceptor 132. The insulating member 128 may be constructed from any insulating material, such as, for example, plastic. In this particular example, the insulating member is constructed from polyetheretherketone (PEEK). The insulating member 128 serves to insulate the various components of the device 100 from heat generated within the susceptor 132.

[0372] The insulating member 128 may also fully or partially support the first and second inductor coils 124, 126. For example, as shown in FIG. 9, the first and second inductor coils 124, 126 are positioned around the insulating member 128 and contact a radially outer surface of the insulating member 128. In some examples, the insulating member 128 does not abut the first and second inductor coils 124, 126. For example, a small gap may exist between the outer surface of the insulating member 128 and the inner surfaces of the first and second inductor coils 124, 126.

[0373] In a particular example, the susceptor 132 , the insulating member 128 and the first and second inductor coils 124 , 126 are coaxial about a central longitudinal axis of the susceptor 132 .

[0374] 10 shows a side, partial cross-section of device 100. Outer cover 102 is shown in this example. The rectangular cross-sectional shape of first and second inductor coils 124, 126 can be more clearly seen.

[0375] The device 100 further includes a support 136 that engages one end of the susceptor 132 to hold the susceptor 132 in place. The support 136 is connected to the second end member 116.

[0376] The device also includes a second printed circuit board 138 associated with the adjustment member 112 .

[0377] The device 100 further includes a second lid / cap 140 and a spring 142 disposed toward a distal end of the device 100. The spring 142 opens the second lid 140 to provide access to the susceptor 132. A user may open the second lid 140 to clean the susceptor 132 and / or the support 136.

[0378] The device 100 further includes an expansion chamber 144 that extends away from the proximal end of the susceptor 132 toward the opening 104 of the device. Disposed at least partially within the expansion chamber 144 is a retention clip 146 that abuts and retains the article 110 when contained within the device 100. The expansion chamber 144 is connected to the end member 106.

[0379] FIG. 10 is an exploded view of the device 100 of FIG. 9 with the outer cover 102 omitted.

[0380] FIG 11A shows a cross section of a portion of the device 100 of FIG 9. FIG 11B shows an enlarged view of a region of FIG 11A. FIGs 11A and 11B show an article 110 contained within a susceptor 132, with the article 110 sized such that its outer surface abuts the inner surface of the susceptor 132 for most efficient heating. The article 110 in this example includes an aerosol-generating material 110a. The aerosol-generating material 110a is positioned within the susceptor 132. The article 110 may also include other components, such as a filter wrapper and / or a cooling structure.

[0381] 11B shows that the outer surface of the susceptor 132 is separated from the inner surfaces of the inductor coils 124, 126 by a distance 150 measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 150 is about 3 mm to 4 mm, about 3 to 3.5 mm, or about 3.25 mm.

[0382] 11B further shows that the outer surface of the insulating member 128 is spaced from the inner surface of the inductor coils 124, 126 by a distance 152 measured in a direction perpendicular to the longitudinal axis 158 of the susceptor 132. In one particular example, the distance 152 is about 0.05 mm. In another example, the distance 152 is substantially 0 mm such that the inductor coils 124, 126 abut and touch the insulating member 128.

[0383] In one example, the wall thickness 154 of the susceptor 132 is between about 0.025 mm and 1 mm, or about 0.05 mm.

[0384] In one example, the length of the susceptor 132 is about 40 mm to 60 mm, about 40 mm to 45 mm, or about 44.5 mm.

[0385] In one example, the wall thickness 156 of the insulating member 128 is between about 0.25 mm and 2 mm, between 0.25 mm and 1 mm, or about 0.5 mm.

[0386] In use, an article 1, 1', 1'', 1''' described herein is inserted into a non-combustion aerosol delivery device, such as device 100 described with reference to Figures 7-11B. At least a portion of the mouthpiece 2, 2', 2'', 2''' of article 1, 1', 1'', 1''' protrudes from non-combustion aerosol delivery device 100 and is placed into the mouth of a user. An aerosol is generated by heating aerosol-generating material 3 using device 100. The aerosol generated by aerosol-generating material 3 travels through mouthpiece 2 to the user's mouth.

[0387] The articles 1, 1', 1'', 1''' described herein are particularly advantageous when used in a non-combustion based aerosol delivery device, such as device 100 described with reference to Figures 7-11B. In particular, it has been surprisingly discovered that the first tubular component 4a has a significant effect on the temperature of the outer surface of the mouthpiece 2, 2', 2'', 2''' of the article 1, 1', 1'', 1'''. As already mentioned, the thickness and porosity and wrapper help to reduce the temperature.

[0388] It has been found that the hollow tubular component of the mouthpiece 2' has a significant effect on the temperature of the outer surface of the mouthpiece 2' of the article 1', for example it has been found that when a hollow tubular component 8 formed from filamentary tow is wrapped in an outer wrapper, such as tipping paper 5, the temperature of the outer wrapper at a longitudinal position corresponding to the position of the hollow tubular component 8 will reach a maximum temperature in use of less than 42°C, preferably less than 40°C, more preferably less than 38°C or less than 36°C.

[0389] Table 1.0 below shows the temperature of the outer surface of the article 1' described herein with reference to Figure 3 when heated using the device 100 described herein with reference to Figures 7-11B. In this example, the axial length of the hollow tubular component 8 is 6 mm, the length of the body of material 6 is 10 mm and the length of the tubular portion 4a is 25 mm. The pressure drop of the body of material 6 of the article 1' is 4.38 mmWG.

[0390] First, second and third temperature measurement probes were used at corresponding first, second and third positions along the mouthpiece 2' of the article 1'. The first position (numbered as position 1 in Table 1.0) was 4 mm from the downstream end 2b of the mouthpiece 2', the second position (numbered as position 2 in Table 1.0) was 8 mm from the downstream end 2b of the mouthpiece 2', and the third position (numbered as position 3 in Table 1.0) was 12 mm from the downstream end 2b of the mouthpiece 2'.

[0391] Thus, the first location is the outer surface of the portion of the mouthpiece 2' in which the hollow tubular component 8 is arranged, and the second and third locations are the outer surface of the portion of the mouthpiece 2' in which the body of material 6 is arranged.

[0392] Testing was performed on the first 9 puffs of the article using standard equipment at environmental conditions of 60% relative humidity and 22°C.

[0393] [Table 1.0]

[0394] The above tests were carried out on an article having the same characteristics as tested article 1' above but with a pressure drop of 8.13 mmWG, and the results are shown in Table 2.0 below.

[0395] [Table 2.0]

[0396] The above tests were carried out on an article having the same characteristics as tested article 1' above but with a pressure drop of 11.88mmWG, and the results are shown in Table 3.0 below.
