Description

[Technical Field]

[0001] This disclosure relates to articles for use in non-flammable aerosol supply systems. [Background technology]

[0002] Certain delivery systems generate aerosols during use, which are then inhaled by the user. For example, a cigarette heating device heats an aerosol-generating substrate, such as a cigarette, to form an aerosol by heating rather than burning the substrate. Such delivery systems generally include a heating device having a heating element, which, when heated, heats the aerosol-generating substrate and releases the aerosol. [Overview of the project]

[0003] According to some embodiments, an article is provided for use in or as part of an aerosol supply system, comprising an aerosol generating material and a heat transfer material for distributing heat from a first region of the aerosol generating material to a second region of the aerosol generating material, wherein the heat transfer material has a thermal conductivity of at least 220 W / mK.

[0004] In some embodiments, the thermal conductivity of the heat transfer material is about 5000 W / mK, 4000 W / mK, 3000 W / mK, 2000 W / mK, or less than 1000 W / mK. In some embodiments, the thermal conductivity of the heat transfer material is about 300 W / mK, 400 W / mK, or greater than 500 W / mK. In some embodiments, the thermal conductivity of the heat transfer material is in the range of approximately 220-5000 W / mK, 220-4000 W / mK, 220-3000 W / mK, 220-2000 W / mK, 220-1000 W / mK, 220-500 W / mK, 300-5000 W / mK, 300-4000 W / mK, 300-3000 W / mK, 300-2000 W / mK, 300-1000 W / mK, 300-500 W / mK, or 220-470 W / mK.

[0005] In some embodiments, the weight of the heat transfer material present in the article ranges from about 1 to 25 mg, 1 to 20 mg, 1 to 15 mg, 1 to 10 mg, or 1 to 5 mg. In some embodiments, the weight ratio of the heat transfer material to the aerosol-forming material is from about 1:10 to 1:100.

[0006] In some embodiments, the heat transfer material includes at least one discrete material portion that is in thermal contact with a first region and a second region of the aerosol-forming material. The heat transfer material can include a single material portion. The heat transfer material can be in the form of a rod, wire, fiber, thread, or ribbon that extends through at least a portion of the aerosol-forming material.

[0007] In some embodiments, the heat transfer material extends through the length of the aerosol-forming material. If the aerosol-forming material is generally cylindrical, the heat transfer material can extend along a portion or all of the length of the material. The heat transfer material can be elongate and can extend parallel to or along the axis of the aerosol-forming material. As described below, the heat transfer material can be fed or extruded into the aerosol-forming material during manufacture of the article.

[0008] In some embodiments, the heat transfer material extends along less than the length of the aerosol-forming material. The heat transfer material can extend along at least 10% of the length of the aerosol-forming material. The heat transfer material can extend along up to about 90% of the length of the aerosol-forming material. In some embodiments, the length of the heating element ranges from 10% to 90%, 10% to 80%, 10% to 70%, 10% to 60%, or 10% to 50% of the length of the aerosol-forming material.

[0009] The heat transfer material is separate from and may be different from the aerosol-generating material. The heat transfer material may include a single material portion, or it may include multiple separate material portions that are in thermal contact with the first and second regions of the aerosol-generating material, respectively. For example, the heat transfer material may be formed from three or more separate material portions within the aerosol-generating material, e.g., 3-20, 3-10, or 3-5 separate material portions.

[0010] In some embodiments, the heat transfer material may be formed from multiple material parts. In some embodiments, the heat transfer material may be more generally distributed through the aerosol-generating material, as opposed to being formed from one or more distinct material parts. In some embodiments, the heat transfer material can be considered to be mixed with the aerosol-generating material. In some embodiments, the heat transfer material is in the form of particles or powder.

[0011] In some embodiments, the heat transfer material is nonmetallic.

[0012] In some embodiments, the heat transfer material contains or includes carbon. The heat transfer material may be formed from or include one of graphene, diamond, graphite, pyrolytic graphite, carbon fiber, graphene fiber, or graphite fiber. Some of these materials have thermal conductivity values ​​of 4000 W / mK for graphene, 2200 W / mK for diamond, and 1700 W / mK for pyrolytic graphite. A backing material such as paper may be provided to the heat transfer material.

[0013] In some embodiments, the aerosol-generating material includes recycled tobacco. As previously stated, a heat transfer material which may contain carbon or graphite can be mixed with the recycled tobacco. Recycled tobacco typically contains wood pulp, but the heat transfer material of this disclosure may replace some or all of the wood pulp.

[0014] In some embodiments, the article is heated by an external heating element located outside the aerosol-generating material. In other embodiments, the article is heated by an internal heating element inserted into the aerosol-generating material during use.

[0015] The heating element inserted into the aerosol generating material may be an electrically heated element, or a susceptor heated by induction heating or magnetic hysteresis heating. The heating element may be part of the article. The heating element may be inserted into the article during manufacturing. Alternatively, the heating element may be part of an aerosol supply device that uses the article, and the insertion of the heating element into the aerosol generating material occurs when the article is inserted into the aerosol supply device.

[0016] Such heating elements may be made of metal.

[0017] In some embodiments, the heat transfer material has openings, holes, or cavities. The article may further comprise an amorphous solid, an active substance, or a fragrance. The amorphous solid, active substance, or fragrance may be placed in one or more openings, holes, or cavities of the heat transfer material.

[0018] According to some embodiments, an aerosol supply system is provided comprising a non-flammable aerosol supply device, a heating element, and the above-mentioned articles.

[0019] In some embodiments, the aerosol supply device includes a power source for supplying power to a heating element, which heats the aerosol-generating material by electrical conduction. This type of heating element may be part of the aerosol supply device.

[0020] In some embodiments, the aerosol supply device comprises a magnetic field generator, and the heating element is a susceptor that heats the aerosol-generating material by induction heating and / or magnetic hysteresis heating.

[0021] In some embodiments, the aerosol supply device comprises a heat source, and the heating element of the article is a second heat transfer material for transferring heat to the aerosol-generating material.

[0022] The susceptor or second heat transfer material may be part of an article or part of an aerosol supply device.

[0023] According to some embodiments, a method is provided for manufacturing an article for use in or as part of an aerosol supply system, wherein the article comprises an aerosol-generating material, and the method includes the step of adding a heat transfer material for distributing heat from a first region of the aerosol-generating material to a second region of the aerosol-generating material, wherein the heat transfer material has a thermal conductivity of at least 220 W / mK.

[0024] The step of adding a heat transfer material may include feeding or extruding the heat transfer material into the aerosol-generating material. Alternatively, the step of adding a heat transfer material may include mixing the heat transfer material with the aerosol-generating material.

[0025] In some embodiments, rods, wires, fibers, threads, or ribbons of the heat transfer material can be fed into the aerosol-generating material during manufacturing. If the aerosol-generating material is formed from multiple pieces of shredded tobacco, the heat transfer material can be fed into the multiple pieces during the manufacturing of the article. As previously mentioned, the heat transfer material may contain carbon and may be graphite, such as graphite fibers.

Consumables may also comprise an aerosol generator, such as a heater that generates heat during use to cause the aerosol-generating material to produce an aerosol. The heater may comprise, for example, a flammable material, an electrically conductive material, or a susceptor.

[0055] A susceptor is a material that can be heated by the penetration of a fluctuating magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material, and the penetration of a fluctuating magnetic field into the conductive material causes inductive heating of the heating material. The heating material may be a magnetic material, and the penetration of a fluctuating magnetic field into the magnetic material causes magnetic hysteresis heating of the heating material. The susceptor may be both conductive and magnetic, and can be heated by both heating mechanisms. A device configured to generate a fluctuating magnetic field is referred to herein as a magnetic field generator.

[0056] Aerosol modifiers are typically located downstream of an aerosol generation region and are configured to modify the generated aerosol by altering, for example, the taste, flavor, acidity, or other properties of the aerosol. Aerosol modifiers may be contained within an aerosol modifier release component that is operable to selectively release the aerosol modifier.

[0057] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may include, for example, one or more of flavorings, colorings, water, and carbon adsorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, thread, or granules. The aerosol modifier does not need to contain a filter material.

[0058] An aerosol generator is a device configured to generate an aerosol from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol-generating material, causing one or more volatile substances to be released from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from an aerosol-generating material without heating. For example, the aerosol generator may be configured to apply one or more of the following to the aerosol-generating material: vibration, high pressure, or electrostatic energy.

[0059] The filament tow materials described herein may include cellulose acetate fiber tow. The filament tow 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-coterephthalate) (PBAT), starch-based materials, cotton, aliphatic polyester materials, and polysaccharide polymers, or combinations thereof. The filament tow may be plasticized using a suitable plasticizer for tow, such as triacetin, which may mean the material is cellulose acetate tow or the tow is not plasticized. The tow can have any suitable specifications; for example, the fibers may have other cross-sections such as "Y" or "X" shapes, the single fineness value may be 2.5 to 15 denier per filament, for example 8.0 to 11.0 denier per filament, and the total fineness value may be 5,000 to 50,000, for example 10,000 to 40,000.

[0060] In the drawings described herein, the same reference numerals are used to indicate equivalent features, articles, or parts.

[0061] Figure 1 is a side cross-sectional view of article 1 for use in an aerosol delivery system.

[0062] Article 1 comprises a mouthpiece 2 and an aerosol generating section connected to the mouthpiece 2. In this example, the aerosol generating section comprises a source of aerosol generating material in the form of a cylindrical rod of aerosol generating material 3. In other examples, the aerosol generating section may comprise a cavity for receiving the source of aerosol generating material. The aerosol generating material may comprise a plurality of strands or fragments of aerosol generating material. For example, the aerosol generating material may comprise a plurality of strands or fragments of an aerosolizable material and / or a plurality of strands or fragments of an amorphous solid, as described below. In some embodiments, the aerosol generating material is composed of a plurality of strands or fragments of an aerosolizable material.

[0063] In this example, a cylindrical rod of aerosol-generating material 3 comprises multiple strands and / or fragments of the aerosol-generating material and is surrounded by a wrapper 10. In this example, the wrapper 10 is a non-permeable wrapper.

[0064] Multiple strands or fragments of the aerosol-generating material may be aligned within the aerosol-generating portion such that their longitudinal dimensions are aligned parallel to the longitudinal axis X-X' of article 1. Alternatively, the strands or fragments may be positioned so that their aligned longitudinal dimensions typically cross the longitudinal axis of the article.

[0065] At least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95% of the strands or flakes may be arranged so that their longitudinal dimensions are aligned parallel to the longitudinal axis of the article. The majority of the strands or flakes may be arranged so that their longitudinal dimensions are aligned parallel to the longitudinal axis of the article. In some embodiments, about 95% to about 100% of the strands or flakes are arranged so that their longitudinal dimensions are aligned parallel to the longitudinal axis of the article. In some embodiments, substantially all of the strands or flakes are arranged in the aerosol-generating portion so that their longitudinal dimensions are aligned parallel to the longitudinal axis of the aerosol-generating portion of the article.

[0066] If the majority of the strands or strips are positioned in the aerosol-generating portion of the article such that their longitudinal axes are parallel to the longitudinal axis of the aerosol-generating portion of the article, the force required to insert the aerosol generator into the aerosol-generating material may be relatively small. This can make the article easier to use.

[0067] In this example, the rod of the aerosol-generating material 3 has a circumference of approximately 22.7 mm. In an alternative embodiment, the rod of the aerosol-generating material 3 can have any suitable circumference, for example, a circumference of approximately 20 mm to approximately 26 mm.

[0068] Referring to Figures 1a to 1d, examples of aerosol-generating materials 3 including heat transfer materials are shown. In Figures 1a to 1c, the aerosol-generating material 3 is schematically shown as being formed from a plurality of strands 31 arranged approximately parallel to the longitudinal axis of article 1.

[0069] The embodiment in Figure 1a has a single fiber 40 of heat transfer material that is centrally located within the aerosol-generating material 3 and extends generally along the axis of article 1. The heat transfer material is formed from graphite fibers that are fed into the aerosol-generating material 3 during manufacturing.

[0070] Figure 1b shows an embodiment having multiple fibers 40 of a heat transfer material dispersed in an aerosol generating material 3.

[0071] Figure 1c shows an embodiment in which the aerosol generating material 3 has two fibers 40 of heat transfer material, but without any heat transfer material in the central region of the aerosol generating material 3.

[0072] Figure 1d shows an embodiment having multiple separate heat transfer material portions 41 dispersed throughout the aerosol-generating material 3.

[0073] Article 1 is configured for use in a non-combustible aerosol supply device that includes an aerosol generator inserted into an aerosol generating section. In this example, the aerosol generator is a heater, and the article is configured to receive the aerosol generator on a rod of aerosol generating material.

[0074] The mouthpiece 2 includes a cooling portion 8, also called a cooling element, which is located immediately downstream and adjacent to the source of the aerosol-generating material 3. In this example, the cooling portion 8 is in contact with the source of the aerosol-generating material. The mouthpiece 2 also, in this example, includes a material body 6 downstream of the cooling portion 8 and a hollow tubular element 4 at the mouth end of article 1, downstream of the material body 6.

[0075] The cooling section 8 comprises a hollow channel having an inner diameter of approximately 1 mm to 4 mm, for example, approximately 2 mm to 4 mm. In this example, the hollow channel has an inner diameter of approximately 3 mm. The hollow channel extends along the entire length of the cooling section 8. In this example, the cooling section 8 comprises a single hollow channel. In alternative embodiments, the cooling section may comprise multiple channels, for example, two, three, or four channels. In this example, the single hollow channel is substantially cylindrical, but in alternative embodiments, other channel shapes / cross-sections may be used. The hollow channel can provide space in which the aerosol drawn into the cooling section 8 can expand and be cooled. In all embodiments, the cooling section is configured to limit the cross-sectional area of ​​one or more hollow channels to restrict the displacement of the cigarette into the cooling section during use.

[0076] Because the non-permeable wrapper 10 has low friction with the aerosol-generating material, strands and / or fragments of the aerosol-generating material can be more easily displaced longitudinally into the cooling section when the aerosol generator is inserted into the rod of the aerosol-generating material. By providing the cooling section 8 directly adjacent to the aerosol-generating material supply source and having an internal channel having a diameter within this range, longitudinal displacement of the strands and / or fragments of the aerosol-generating material is reduced when the aerosol generator is inserted into the rod of the aerosol-generating material, which is advantageous. Reducing the displacement of the aerosol-generating material during use results in a more consistent packing density of the aerosol-generating material along the length of the rod and / or within the cavity, which is advantageous as it enables more consistent and improved aerosol generation.

[0077] The cooling section 8 preferably has a radial wall thickness that can be measured, for example, using a caliper. The wall thickness of the cooling section 8 for a given outer diameter of the cooling section defines the inner diameter of the cavity enclosed by the wall of the cooling section 8. The cooling section 8 can have a wall thickness of at least about 1.5 mm to a maximum of about 2 mm. In this example, the cooling section 8 has a wall thickness of about 2 mm. Providing a cooling section 8 with a wall thickness within this range improves the retention of the aerosol-generating material source in the aerosol-generating section during use by reducing the longitudinal displacement of the strands and / or fragments of the aerosol-generating material when the aerosol generator is inserted into an article.

[0078] The cooling section 8 is formed from a filament tow. Multiple layers of paper wound parallel to each other and joined at the seams to form the cooling section 8, or other configurations such as spirally wound layers of paper, cardboard tubes, tubes formed using a condensed paper type process, molded or extruded plastic tubes, may be used. The cooling section 8 is manufactured to have sufficient rigidity to withstand axial compressive forces and bending moments that may occur during manufacturing and in use of Article 1.

[0079] The wall material of the cooling section 8 may be relatively non-porous, and at least 90% of the aerosols generated by the aerosol generating material 3 pass longitudinally through one or more hollow channels rather than through the wall material of the cooling section 8. For example, at least 92% or at least 95% of the aerosols generated by the aerosol generating material 3 can pass longitudinally through one or more hollow channels.

[0080] The filament tow forming the cooling portion 8 preferably has a total fineness of less than 45,000, more preferably less than 42,000. This total fineness has been shown to allow for the formation of a cooling portion 8 that is not too dense. The total fineness is preferably at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filament tow forming the cooling portion 8 has a total fineness of 25,000 to 45,000, more preferably 35,000 to 45,000. The cross-sectional shape of the tow filament is preferably "Y" shaped, but in other embodiments, other shapes such as an "X" shaped filament may be used.

[0081] The filament tow forming the cooling portion 8 preferably has a denier per filament greater than 3. It has been found that this denier per filament allows for the formation of tubular elements 4 that are not too dense. The denier per filament is preferably at least 4, more preferably at least 5. In a preferred embodiment, the filament tow forming the hollow tubular elements 4 has a denier per filament of 4 to 10, more preferably 4 to 9. In one example, the filament tow forming the cooling portion 8 is formed from cellulose acetate and has an 8Y40,000 tow containing 18% plasticizer, such as triacetin.

[0082] The density of the material forming the cooling portion 8 is preferably at least about 0.20 grams per cubic centimeter (g / cc), more preferably at least about 0.25 g / cc. The density of the material forming the cooling portion 8 is preferably less than about 0.80 grams per cubic centimeter (g / cc), more preferably less than 0.6 g / cc. In some embodiments, the density of the material forming the cooling portion 8 is 0.20 to 0.8 g / cc, more preferably 0.3 to 0.6 g / cc, or 0.4 g / cc to 0.6 g / cc, or about 0.5 g / cc. These densities have been found to provide a good balance between the higher hardness given by the higher density material and minimizing the total weight of the article. For the purposes of this disclosure, “density” of the material forming the cooling portion 8 refers to the density of the filament tow forming the element into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the material forming the cooling portion 8 by the total volume of the material forming the cooling portion 8, the total volume can be calculated using a suitable measurement of the material forming the cooling portion 8, for example, obtained using a caliper. If necessary, the appropriate dimensions can be measured using a microscope.

[0083] The length of the cooling portion 8 is preferably less than approximately 30 mm. More preferably less than approximately 25 mm. Even more preferably less than approximately 20 mm. In addition or instead, the length of the cooling portion 8 is preferably at least approximately 10 mm. The length of the cooling portion 8 is preferably at least approximately 15 mm. In some preferred embodiments, the length of the cooling portion 8 is approximately 15 mm to approximately 20 mm, more preferably approximately 16 mm to approximately 19 mm. In this example, the length of the cooling portion 8 is 19 mm.

[0084] The cooling section 8 is positioned around and defines a void within the mouthpiece 2 that acts as a cooling section. The void provides a chamber through which heated volatile components generated by the rod of the aerosol-generating material 3 flow. The cooling section 8 is hollow to provide a chamber for aerosol accumulation, but is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and use of the article 1. The cooling section 8 results in a physical displacement between the aerosol-generating material 3 and the material body 6. The physical displacement introduced by the cooling section 8 can provide a temperature gradient along the length of the cooling section 8.

[0085] Mouthpiece 2 is 110mm 3 It is preferable to have a cavity having an internal volume exceeding 110 mm. It has been shown that providing at least this volumetric cavity enables improved aerosol formation. The mouthpiece 2 is formed, for example, within the cooling portion 8, and 110 mm 3 More preferably 130 mm 3 It is more preferable to have a cavity with an internal volume greater than 130 mm² to allow for further improvement of the aerosol. In some examples, the internal cavity is approximately 130 mm². 3 ~approx. 230mm 3 For example, approximately 134mm 3 or 227mm 3 It has a volumetric section.

[0086] The cooling section 8 may be configured to create a temperature difference of at least 40 degrees Celsius between the heated volatile components entering the first upstream end of the cooling section 8 and the heated volatile components exiting from the second downstream end of the cooling section 8. Preferably, the cooling section 8 is configured to create a temperature difference of at least 60 degrees Celsius, preferably at least 80 degrees Celsius, and more preferably at least 100 degrees Celsius, between the heated volatile components entering the first upstream end of the cooling section 8 and the heated volatile components exiting from the second downstream end of the cooling section 8. This temperature difference along the length of the cooling section 8 protects the temperature-sensitive material body 6 from the high temperature of the aerosol-generating material 3 when heated.

[0087] In use, the aerosol generating portion can exhibit a pressure drop of about 15 to about 40 mmH2O. In some embodiments, the aerosol generating portion exhibits a pressure drop of about 15 to about 30 mmH2O across the aerosol generating portion.

[0088] The aerosol generating material can have a packing density of about 400 mg / cm 3 to about 900 mg / cm 3 . If the packing density is higher than this, it becomes difficult to insert the aerosol generator of the aerosol supply device into the aerosol generating material, and the pressure drop may increase. A packing density of less than 400 mg / cm 3 can reduce the rigidity of the article. Furthermore, if the packing density is too low, the aerosol generating material cannot effectively grip the aerosol generator of the aerosol supply.

[0089] At least about 70% of the volume of the aerosol generating portion is filled with the aerosol generating material. In some embodiments, the aerosol generating material fills about 75% to about 85% of the volume of the cavity.

[0090] In this embodiment, the non-permeable wrapper 10 surrounding the rod of aerosol-generating material comprises aluminum foil. In other embodiments, the wrapper 10 comprises a paper wrapper, which optionally comprises a barrier coating that makes the wrapper material substantially non-permeable. Aluminum foil has been found to be particularly effective in promoting aerosol formation within the aerosol-generating material 3. In this example, the aluminum foil has a metal layer about 6 μm thick. In this example, the aluminum foil has a paper backing. However, in alternative configurations, the aluminum foil may have other thicknesses, e.g., 4 μm to 16 μm. The aluminum foil does not need to have a paper backing; it may have a backing made of another material, for example, that helps to give the foil adequate tensile strength, or it may not have a backing material at all. A metal layer or foil other than aluminum may be used. The total thickness of the wrapper is preferably 20 μm to 60 μm, more preferably 30 μm to 50 μm, which can provide a wrapper with adequate structural integrity and heat transfer properties. The tensile force that can be applied to the wrapper before it breaks may be greater than 3,000 grams, for example, 3,000 to 10,000 grams or 3,000 to 4,500 grams. If the wrapper includes paper or a paper backing, i.e., a cellulose-based material, the wrapper may have a basis weight greater than about 30 gsm. For example, the wrapper may have a basis weight of about 40 gsm to about 70 gsm. Such a basis weight gives the rod of the aerosol-generating material high rigidity. The high rigidity provided by a wrapper with a basis weight in this range may give the rod of the aerosol-generating material 3 greater resistance to the formation of wrinkles or other deformations caused by forces on the article during use, for example, when inserting an article into a device and / or when inserting a heat generator into an article. Providing a rod of aerosol-generating material with high rigidity may be advantageous when multiple strands or strips of the aerosol-generating material are aligned within the aerosol-generating portion such that their longitudinal dimensions are aligned parallel to the longitudinal axis.This is because strands or fragments of aerosol-generating material aligned longitudinally can impart lower stiffness to the rod of the aerosol-generating material than when the strands or fragments are not aligned. The high stiffness of the rod of the aerosol-generating material allows the article to withstand greater forces during use.

[0091] In this example, the non-permeable wrapper 10 is also substantially non-permeable. In alternative embodiments, the wrapper 10 preferably has permeability of less than 100 cholesta units, more preferably less than 60 cholesta units. For example, it has been found that a low-permeability wrapper having permeability of less than 100 cholesta units, more preferably less than 60 cholesta units, enhances aerosol formation in the aerosol-generating material 3. While we do not wish to be bound by theory, this is assumed to be due to less loss of aerosol compounds through the wrapper 10. The permeability of the wrapper 10 can be measured according to ISO 2965:2009 for measuring the permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.

[0092] The material body 6 and the hollow tubular element 4 each define a substantially cylindrical overall shape and share a common longitudinal axis. The material body 6 is wrapped in a first plug wrap 7. The first plug wrap 7 preferably has a basis weight of less than 50 gsm, more preferably about 20 gsm to 40 gsm. The first plug wrap 7 preferably has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The first plug wrap 7 is preferably a non-porous plug wrap with permeability of, for example, less than 100 cholesta units, for example less than 50 cholesta units. However, in other embodiments, the first plug wrap 7 may be a porous plug wrap with permeability of, for example, more than 200 cholesta units.

[0093] The length of the material body 6 is preferably less than about 15 mm. More preferably, the length of the material body 6 is less than about 12 mm. In addition or alternatively, the length of the material body 6 is at least about 5 mm. The length of the material body 6 is preferably at least about 8 mm. In some preferred embodiments, the length of the material body 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 12 mm, and most preferably about 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. In this example, the length of the material body 6 is 10 mm.

[0094] In this example, material 6 is formed from filament tow. In this example, the tow used for material 6 has a denier per filament (dpf) of 5 and a total fineness of 25,000. In this example, the tow comprises plasticized cellulose acetate tow. The plasticizer used in the tow contains approximately 9% by weight of tow. In this example, the plasticizer is triacetin. In other examples, different materials may be used to form material 6. For example, material 6 may be formed from paper instead of tow, similar to paper filters known to be used in cigarettes. For example, paper or other cellulosic material may be provided as one or more parts of a sheet material, which is folded and / or crimped to form material 6. The sheet material may have a basis weight of 15 gsm to 60 gsm, for example, 20 to 50 gsm. The sheet material may have a basis weight of, for example, 15-25 gsm, 25-30 gsm, 30-40 gsm, 40-45 gsm, and 45-50 gsm. In addition or alternatively, the sheet material may have a width of 50 mm to 200 mm, for example, 60 mm to 150 mm, or 80 mm to 150 mm. For example, the sheet material may have a basis weight of 20-50 gsm and a width of 80 mm to 150 mm. This allows, for example, a cellulose-based material to have a suitable pressure drop for articles having the dimensions described herein.

[0095] Alternatively, the material 6 may be formed from a tow other than cellulose acetate, such as polylactic acid (PLA), other materials described herein for filament tow, or similar materials. The tow is preferably formed from cellulose acetate. Whether formed from cellulose acetate or another material, the tow preferably has a density of at least 5 d.pf. To obtain a sufficiently uniform material 6, the tow preferably has a density of 12 d.pf or less, preferably 11 d.pf or less, and more preferably 10 d.pf or less per filament.

[0096] The total fineness of the tow forming the material body 6 is preferably up to 30,000, more preferably up to 28,000, and even more preferably up to 25,000. These total fineness values ​​provide a tow that occupies a smaller proportion of the cross-sectional area of ​​the mouthpiece 2, resulting in a smaller pressure drop across the mouthpiece 2 than a tow with a higher total fineness value. For the appropriate hardness of the material body 6, the tow preferably has a total fineness of at least 8,000, more preferably at least 10,000. The denier per filament is preferably 5 to 12, and the total fineness is preferably 10,000 to 25,000. The cross-sectional shape of the tow filament is preferably "Y" shaped, but in other embodiments, other shapes such as "X" shaped filaments with the same dpf and total fineness values ​​as provided herein may be used.

[0097] Regardless of the material used to form the material body 6, the pressure drop across the material body 6 may be, for example, 0.3 to 5 mmWG per 1 mm of length of the material body 6, or for example, 0.5 mmWG to 2 mmWG per 1 mm of length of the material body 6. The pressure drop may be, for example, 0.5 to 1 mmWG per 1 mm of length, 1 to 1.5 mmWG per 1 mm of length, or 1.5 to 2 mmWG per 1 mm of length. The total pressure drop across the material body 6 may be, for example, 3 mmWG to 8 mmWG, or 4 mmWG to 7 mmWG. The total pressure drop across the material body 6 may be about 5, 6, or 7 mmWG.

[0098] As shown in Figure 1, the mouthpiece 2 of article 1 comprises an upstream end 2a adjacent to the rod of the aerosol-generating material 3 and a downstream end 2b away from the rod of the aerosol-generating material 3. At the downstream end 2b, the mouthpiece 2 has a hollow tubular element 4 formed from a filament tow. This has been shown to be advantageous as it significantly reduces the temperature of the outer surface of the mouthpiece 2 at the downstream end 2b of the mouthpiece that comes into contact with the consumer's mouth during use of article 1. In addition, the use of the tubular element 4 has also been shown to significantly reduce the temperature of the outer surface of the mouthpiece 2 upstream of the tubular element 4. While we do not wish to be bound by theory, it is hypothesized that this is because the tubular element 4 allows the aerosol to pass through near the center of the mouthpiece 2, thereby suppressing the transfer of heat from the aerosol to the outer surface of the mouthpiece 2.

[0099] The "wall thickness" of the hollow tubular element 4 corresponds to the thickness of the wall of the tube 4 in the radial direction. This can be measured, for example, using a caliper. It is advantageous for the wall thickness to be greater than 0.9 mm, more preferably greater than 1.0 mm. It is preferable that the wall thickness is substantially constant around the entire wall of the hollow tubular element 4. However, if the wall thickness is not substantially constant, the wall thickness is preferably greater than 0.9 mm, more preferably greater than 1.0 mm, at any point around the hollow tubular element 4. In this example, the wall thickness of the hollow tubular element 4 is approximately 1.3 mm.

[0100] The length of the hollow tubular element 4 is preferably less than about 20 mm. More preferably, the length of the hollow tubular element 4 is less than about 15 mm. Even more preferably, the length of the hollow tubular element 4 is less than about 10 mm. In addition or alternatively, the length of the hollow tubular element 4 is at least about 5 mm. The length of the hollow tubular element 4 is preferably at least about 6 mm. In some preferred embodiments, the length of the hollow tubular element 4 is about 5 mm to about 20 mm, more preferably about 6 mm to about 10 mm, even more preferably about 6 mm to about 8 mm, most preferably about 6 mm, 7 mm, or about 8 mm. In this example, the length of the hollow tubular element 4 is 7 mm.

[0101] The density of the hollow tubular element 4 is preferably at least about 0.25 grams per cubic centimeter (g / cc), more preferably at least about 0.3 g / cc. The density of the hollow tubular element 4 is preferably less than about 0.75 grams per cubic centimeter (g / cc), more preferably less than 0.6 g / cc. In some embodiments, the density of the hollow tubular element 4 is 0.25 to 0.75 g / cc, more preferably 0.3 to 0.6 g / cc, more preferably 0.4 g / cc to 0.6 g / cc, or about 0.5 g / cc. These densities have been shown to provide a good balance between the higher hardness provided by the higher density material and the lower heat transfer properties of the lower density material. For the purposes of this disclosure, “density” of the hollow tubular element 4 refers to the density of the filament tow forming the element into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the hollow tubular element 4 by the total volume of the hollow tubular element 4, which can be calculated using appropriate measurements of the hollow tubular element 4, for example, obtained using a caliper. If necessary, appropriate dimensions can be measured using a microscope.

[0102] The filament tow forming the hollow tubular element 4 preferably has a total fineness of less than 45,000, more preferably less than 42,000. This total fineness has been shown to allow for the formation of tubular elements 4 that are not too dense. The total fineness is preferably at least 20,000, more preferably at least 25,000. In a preferred embodiment, the filament tow forming the hollow tubular element 4 has a total fineness of 25,000 to 45,000, more preferably 35,000 to 45,000. The cross-sectional shape of the tow filaments is preferably "Y" shaped, but in other embodiments, other shapes such as "X" shaped filaments may be used.

[0103] The filament tow forming the hollow tubular element 4 preferably has a denier per filament greater than 3. This denier per filament has been shown to enable the formation of tubular elements 4 that are not too dense. The denier per filament is preferably at least 4, more preferably at least 5. In a preferred embodiment, the filament tow forming the hollow tubular member 4 has a denier per filament of 4 to 10, more preferably 4 to 9. In one example, the filament tow forming the hollow tubular element 4 is formed from cellulose acetate and has a tow of 7.3Y36,000 containing 18% plasticizer, such as triacetin.

[0104] The hollow tubular element 4 preferably has an inner diameter greater than 3.0 mm. If the inner diameter is smaller than this, the velocity of the aerosol that passes through the mouthpiece 2 to the consumer's mouth will be faster than desired, causing the aerosol to become too hot, for example, reaching a temperature greater than 40°C or 45°C. The hollow tubular element 4 more preferably has an inner diameter greater than 3.1 mm, and even more preferably greater than 3.5 mm or 3.6 mm. In one embodiment, the inner diameter of the hollow tubular element 4 is about 4.7 mm.

[0105] The hollow tubular element 4 preferably contains 15% to 22% by weight of a plasticizer. In the case of cellulose acetate tow, the plasticizer is preferably triacetin, but other plasticizers such as polyethylene glycol (PEG) may be used. The hollow tubular element 4 more preferably contains 16% to 20% by weight of a plasticizer, for example, about 17%, about 18%, or about 19% of a plasticizer.

[0106] In this example, the first hollow tubular element 4, the material body 6, and the cooling portion 8 are combined using a second plug wrap 9, which is wrapped around all three parts. The second plug wrap 9 preferably has a basis weight of less than 50 gsm, more preferably about 20 gsm to 45 gsm. The second plug wrap 9 preferably has a thickness of 30 μm to 60 μm, more preferably 35 μm to 45 μm. The second plug wrap 9 is preferably a non-porous plug wrap with an air permeability of less than 100 cholesta units, for example, less than 50 cholesta units. However, in an alternative embodiment, the second plug wrap 9 may be a porous plug wrap with an air permeability of, for example, more than 200 cholesta units.

[0107] In this example, article 1 has a circumference of approximately 23 mm. In other examples, the article may be provided in any of the formats described herein, for example, having a circumference of 20 mm to 26 mm. Since the article is heated to release an aerosol, improved heating efficiency can be achieved by using an article with a smaller circumference within this range, for example, less than 23 mm. It has also been found that an article circumference greater than 19 mm is particularly effective in achieving improved aerosol delivery by heating while maintaining a suitable product length. Articles with a circumference of 20 mm to 24 mm, more preferably 20 mm to 23 mm, have been found to offer a good balance between effective aerosol delivery and efficient heating.

[0108] The tip paper 5 is wrapped around the entire length of the mouthpiece 2 and a portion of the rod of the aerosol-generating material 3, and has adhesive on its inner surface to connect the mouthpiece 2 and the rod 3. In this example, the rod of the aerosol-generating material 3 is wrapped in a wrapper 10 that forms a first wrapping material, and the tip paper 5 forms an outer wrapping material that extends at least partially over the rod of the aerosol-generating material 3 to connect the mouthpiece 2 and the rod 3. In some examples, the tip paper may extend only partially over the rod of the aerosol-generating material.

[0109] In this example, the tip paper 5 extends 5 mm over the rod of the aerosol generating material 3, but instead, it may extend 3 mm to 10 mm, or more preferably 4 mm to 6 mm, over the rod 3 to securely attach the mouthpiece 2 to the rod 3. The tip paper can have a basis weight of more than 20 gsm, for example more than 25 gsm, or preferably more than 30 gsm, for example 37 gsm. It has been found that basis weights in this range provide a tip paper that has sufficient flexibility to wrap around the article 1 and adhere to the tip paper itself along the longitudinal overlap seams of the paper, while having acceptable tensile strength. After being wrapped around the mouthpiece, the circumference of the tip paper 5 is approximately 23 mm.

[0110] The article has a permeability level of about 10% of the aerosol drawn through the article. In an alternative embodiment, the article may have a permeability level of 1% to 20%, for example, 1% to 12%, of the aerosol drawn through the article. These levels of permeability help to increase the concentration of aerosol inhaled by the user at the mouthpiece 2b and assist in the aerosol cooling process. The vents are provided directly on the mouthpiece 2 of the article 1. In this example, the vents are provided on the cooling section 8, which has been found to be particularly advantageous in assisting the aerosol generation process. In this case, the vents are provided by perforations 12 formed as a single row of laser perforations located 13 mm from the mouthpiece 2b downstream of the mouthpiece 2. In an alternative embodiment, two or more rows of perforation perforations may be provided. These perforations pass through the tip paper 5, the second plug wrap 9, and the cooling section 8. In an alternative embodiment, the vents may be provided at other locations on the mouthpiece, for example, on the material body 6 or the first tubular element 4. The article is preferably configured such that the perforations are provided approximately 28 mm or less from the upstream end of the article, preferably 20 mm to 28 mm from the upstream end of the article. In this example, the opening is provided approximately 25 mm from the upstream end of the article.

[0111] Figure 2a is a side cross-sectional view of a further article 1' comprising a capsule-containing mouthpiece 2'. Figure 2b is a cross-sectional view of the capsule-containing mouthpiece shown in Figure 2a, passing through the line A-A'. Article 1' and the capsule-containing mouthpiece 2' are the same as article 1 and mouthpiece 2 shown in Figure 1, except that the aerosol modifier is provided in the form of a capsule 11 in this example within the material body 6, and an oil-resistant first plug wrap 7' surrounds the material body 6. In other examples, the aerosol modifier may be provided in other forms, such as a material injected into the material body 6, or it may be provided in a thread, for example, a thread that holds a flavoring or other aerosol modifier, which may also be placed within the material body 6.

[0112] The capsule 11 may include a destructible capsule, such as a capsule having a solid, fragile shell surrounding a liquid payload. In this example, a single capsule 11 is used. The capsule 11 is completely embedded within the material body 6. In other words, the capsule 11 is completely enclosed by the material forming the material body 6. In other examples, multiple destructible capsules, such as two, three or more destructible capsules, may be arranged within the material body 6. The length of the material body 6 can be increased to accommodate the required number of capsules. In examples using multiple capsules, the individual capsules may be identical to each other, or they may differ from each other in size and / or capsule payload. In other examples, there may be multiple material bodies 6, each containing one or more capsules.

[0113] The capsule 11 has a core-shell structure. In other words, the capsule 11 includes a shell that encapsulates a liquid, such as a flavoring or other auxiliary agent, which may be, for example, one of the flavorings or aerosol modifiers described herein. The user can rupture the capsule shell to release the flavoring or other auxiliary agent into the material body 6. The first plug wrap 7' may include a barrier coating that makes the material of the plug wrap substantially impermeable to the liquid payload of the capsule 11. Alternatively or in addition, the second plug wrap 9 and / or tip paper 5 may include a barrier coating that makes the material of the plug wrap and / or tip paper substantially impermeable to the liquid payload of the capsule 11.

[0114] In this example, capsule 11 is spherical and has a diameter of approximately 3 mm. In other examples, other shapes and sizes of capsules may be used. For example, capsules may have a diameter of less than 4 mm, or less than 3.5 mm, or less than 3.25 mm. In alternative embodiments, capsules may have a diameter greater than approximately 3.25 mm, for example greater than 3.5 mm, or greater than 4 mm. The total weight of capsule 11 may be in the range of approximately 10 mg to approximately 50 mg.

[0115] In this example, the capsule 11 is positioned at the longitudinal center of the material 6. That is, the center of the capsule 11 is positioned 5 mm from each end of the material 6. In this example, the center of the capsule is positioned 36 mm from the upstream end of the article 1. The capsule is positioned such that its center is preferably 28 mm to 38 mm from the upstream end of the article 1, more preferably 34 mm to 38 mm from the upstream end of the article 1. In this example, the center of the capsule is positioned 12 mm from the downstream end of the mouthpiece 2b. Positioning the capsule in this location enhances the volatilization of the capsule contents because the capsule is close to the aerosol-generating portion of the article that is heated during use, and allows the user to easily reach and burst the capsule with their fingers because it is sufficiently far from the aerosol-generating portion that is inserted into the aerosol supply system during use.

[0116] In other examples, the capsule 11 may be located at a position other than the longitudinal center of the material 6, i.e., closer to the downstream end than the upstream end of the material 6, or closer to the upstream end than the downstream end of the material 6. The mouthpiece 2' is preferably configured such that the capsule 11 and the vent hole 12 are offset from each other in the longitudinal direction within the mouthpiece 2'. For example, the vent hole 12 may be located just upstream of the capsule position, i.e., about 1 mm to about 10 mm upstream of the capsule position.

[0117] The aerosol-generating material comprises a sheet or shredded sheet of an aerosolizable material. The aerosolizable material is arranged to generate an aerosol when heated.

[0118] A sheet or shredded sheet comprises a first surface and a second surface opposite to the first surface. The dimensions of the first and second surfaces are identical. The first and second surfaces of the sheet or shredded sheet can have any shape. For example, the first and second surfaces may be square, rectangular, oval, or circular. Irregular shapes are also conceivable.

[0119] The first and / or second surfaces of the sheet or shredded sheet may be relatively uniform (for example, relatively smooth), or they may be uneven or irregular in shape. For example, the first and / or second surfaces of the sheet may be textured or patterned to define a relatively rough surface. In some embodiments, the first and / or second surfaces are relatively rough.

[0120] The smoothness of the first and second surfaces may be influenced by several factors, including the surface density of the sheet or shredded sheet, the properties of the components constituting the aerosolizable material, or whether the surface of the material has been treated to give it a pattern or texture, such as by embossing, engraving, or other means.

[0121] The areas of the first and second faces are defined, respectively, by a first dimension (e.g., width) and a second dimension (e.g., length). The measured values ​​of the first and second dimensions may have a ratio greater than 1:1, and therefore, a sheet or shredded sheet may have an "aspect ratio" of 1:1 or greater than 1:1. As used herein, the term "aspect ratio" is the ratio of the measured value of the first dimension of the first or second face to the measured value of the second dimension of the first or second face. An "aspect ratio of 1:1" means that the measured value of the first dimension (e.g., width) and the measured value of the second dimension (e.g., length) are the same. An "aspect ratio greater than 1:1" means that the measured value of the first dimension (e.g., width) and the measured value of the second dimension (e.g., length) are different. In some embodiments, the first and second surfaces of the sheet or shredded sheet have an aspect ratio greater than 1:1, for example, 1:2, 1:3, 1:4, 1.5, 1:6, 1:7, or higher.

[0122] A shredded sheet may comprise one or more strands or fragments of the aerosolizable material. In some embodiments, a shredded sheet comprises multiple (e.g., two or more) strands or fragments of the aerosolizable material. The strands or fragments of the aerosolizable material may have an aspect ratio of 1:1. In some embodiments, the strands or fragments of the aerosolizable material may have an aspect ratio greater than 1:1. In some embodiments, the strands or fragments of the aerosolizable material may have an aspect ratio of about 1.5 to about 1:16, i.e., about 1.5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, or 1:12. If the aspect ratio of the strands or fragments is greater than 1:1, the strands or fragments include a longitudinal dimension or length extending between a first end of the strand or fragment and a second end of the strand or fragment.

[0123] When a shredded sheet comprises multiple strands or flakes of material, the dimensions of each strand or flake may vary between different strands or flakes. For example, a shredded sheet may include a first group of strands or flakes and a second group of strands or flakes, where the dimensions of the strands or flakes in the first group differ from those of the strands or flakes in the second group. In other words, the multiple strands or flakes may include a first group of strands or flakes having a first aspect ratio and a second group of strands or flakes having a second aspect ratio different from the first aspect ratio.

[0124] The first dimension of the strand or flake of the aerosolizable material, i.e., the cutting width, is 0.9 mm to 1.5 mm. If a strand or flake of the aerosolizable material with a cutting width of less than 0.9 mm is incorporated into an article for use in a non-combustible aerosol supply system, the pressure drop across the article may increase to a level that makes the article unsuitable for use in a non-combustible aerosol supply device. However, if the strand or flake has a cutting width greater than 2 mm (e.g., more than 2 mm), it may be difficult to insert the strand or flake of the aerosolizable material into the article during manufacturing. In a preferred embodiment, the cutting width of the strand or flake of the aerosolizable material is about 1 mm to 1.5 mm.

[0125] The strands or fragments of the material are formed by shredding a sheet of aerosolizable material. The sheet of aerosolizable material may be cut transversely, for example, by a cross-cut shredding process, so as to define the cutting width as well as the cutting length of the strands or fragments of the aerosolizable material. The cutting length of the shredded aerosolizable material is preferably at least 5 mm, for example, at least 10 mm, or at least 20 mm. The cutting length of the shredded aerosolizable material may be less than 60 mm, less than 50 mm, or less than 40 mm.

[0126] In some embodiments, a plurality of strands or fragments of the aerosolizable material are provided, and at least one of the plurality of strands or fragments of the aerosolizable material has a length greater than about 10 mm. Alternatively, or in addition, at least one of the plurality of strands or fragments of the aerosolizable material may have a length of about 10 mm to about 60 mm, or about 20 mm to about 50 mm. Each of the plurality of strands or fragments of the aerosolizable material may have a length of about 10 mm to about 60 mm, or about 20 mm to about 50 mm.

[0127] A sheet or shredded sheet of the aerosolizable material has a thickness of at least about 100 μm. The sheet or shredded sheet may have a thickness of at least about 120 μm, 140 μm, 160 μm, 180 μm, or 200 μm. In some embodiments, the sheet or shredded sheet has a thickness of about 150 μm to about 300 μm, about 151 μm to about 299 μm, about 152 μm to about 298 μm, about 153 μm to about 297 μm, about 154 μm to about 296 μm, about 155 μm to about 295 μm, about 156 μm to about 294 μm, about 157 μm to about 293 μm, about 158 ​​μm to about 292 μm, about 159 μm to about 291 μm, or about 160 μm to about 290 μm. In some embodiments, the sheet or shredded sheet has a thickness of approximately 170 μm to approximately 280 μm, approximately 180 to approximately 270 μm, approximately 190 to approximately 260 μm, approximately 200 μm to approximately 250 μm, or approximately 210 μm to approximately 240 μm.

[0128] The thickness of the sheet or shredded sheet may vary between the first and second surfaces. In some embodiments, individual pieces or sections of the aerosolizable material have a minimum thickness of about 100 μm over their area. In some cases, individual pieces or sections of the aerosolizable material have a minimum thickness of about 0.05 mm or about 0.1 mm over their area. In some cases, individual pieces, strands, or sections of the aerosolizable material have a maximum thickness of about 1.0 mm over their area. In some cases, individual pieces or sections of the aerosolizable material have a maximum thickness of about 0.5 mm or about 0.3 mm over their area.

[0129] The thickness of the sheet can be determined using ISO 534:2011 "Paper and cardboard - Measurement of thickness".

[0130] If the sheet or shredded sheet of aerosolizable material is too thick, heating efficiency may decrease. This can negatively affect power consumption during use, for example, the power consumed to release fragrance from the aerosolizable material. Conversely, if the aerosolizable material is too thin, it may be difficult to manufacture and handle. Very thin materials are more difficult to cast, are brittle, and may interfere with aerosol formation during use.

[0131] It is assumed that if a sheet or shredded sheet of aerosolizable material is too thin (e.g., less than 100 μm), it may not have sufficient strength to be pulled longitudinally without breaking.

[0132] Approximately 100g / m 2 ~about 250g / m 2 Sheets or shredded sheets having a thickness of at least about 100 μm along with a surface density are assumed to be more resistant to tearing, cracking, or other deformation during manufacturing. A thickness of at least about 100 μm can have a favorable effect on the overall structural integrity and strength of the sheet or shredded sheet. For example, this thickness can have good tensile strength, making it relatively easy to process.

[0133] The thickness of a sheet or shredded sheet is thought to be related to its surface density. In other words, increasing the thickness of a sheet or shredded sheet can increase its surface density.

[0134] Conversely, reducing the thickness of a sheet or shredded sheet may decrease the surface density of the sheet or shredded sheet. To avoid misunderstanding, when surface density is referred to herein, it refers to the average surface density calculated for a given piece, strand, section, or sheet of aerosolizable material, which is calculated by measuring the surface area and weight of a given piece, strand, section, or sheet of aerosolizable material.

[0135] The aerosol-generating material sheet or shredded sheet weighs approximately 100 g / m². 2 ~about 250g / m 2 It has a surface density of approximately 110 g / m². The sheet or shredded sheet has a surface density of approximately 110 g / m². 2 ~about 240g / m 2 , about 120g / m 2 ~about 230g / m 2 , about 130g / m 2 ~about 220g / m 2 , or approximately 140g / m 2 ~about 210g / m 2 It can have a surface density of approximately 130 g / m². In some embodiments, the sheet or shredded sheet may have a surface density of approximately 130 g / m². 2 ~Approx. 190g / m 2 , about 140g / m 2 ~Approx. 180g / m 2 , about 150g / m 2 ~Approx. 170g / m 2 It has a surface density of approximately 160 g / m². In a preferred embodiment, the sheet or shredded sheet has a surface density of approximately 160 g / m². 2 It has a surface density.

[0136] Approximately 100g / m 2 ~about 250g / m 2 The surface density is thought to contribute to the strength and flexibility of the sheet or shredded sheet. Furthermore, a rod containing shredded sheets of aerosolizable material having a surface density of approximately 180 gsm and a minimum thickness of 220-230 μm may be filled in such a way that the aerosolizable material remains in place within the rod, maintains a desired weight of tobacco material (e.g., approximately 300 mg) within the rod, and delivers acceptable sensory stimuli (e.g., taste and smell) when heated in a non-combustible aerosol supply device.

[0137] The flexibility of a sheet or shredded sheet is considered to depend, at least in part, on the thickness and surface density of the sheet or shredded sheet. Thicker sheets or shredded sheets may be less flexible than thinner sheets or shredded sheets. Also, the higher the surface density of the sheet, the lower the flexibility of the sheet or shredded sheet. The combinations of thickness and surface density of the aerosolizable material described herein are considered to provide relatively flexible sheets or shredded sheets. When the aerosolizable material is incorporated into an article for use in a non-combustible aerosol supply device, this flexibility can yield various advantages. For example, when inserting an aerosol generator into the aerosolizing material, the strands or fragments can be easily deformed and bent, facilitating the insertion of the aerosol generator (e.g., a heater) into the material, and improving the retention of the aerosol generator by the aerosolizable material.

[0138] The surface density of a sheet or shredded sheet of aerosol-generating material can affect the roughness of the first and second surfaces of the sheet or shredded sheet. By changing the surface density, the roughness of the first and / or second surfaces can be adjusted.

[0139] The average volume density of a sheet or shredded sheet of aerosol-generating material can be calculated from the sheet thickness and surface density. The average volume density is approximately 0.2 g / cm³. 3 Super, about 0.3g / cm 3 Or approximately 0.4 g / cm³ 3 This may also be the case. In some embodiments, the average volume density is about 0.2 g / cm³. 3 ~Approx. 1g / cm 3 , about 0.3g / cm 3 ~Approx. 0.9g / cm 3 Approximately 0.4 g / cm³ 3 ~Approx. 0.9g / cm 3 , about 0.5g / cm 3 ~Approx. 0.9g / cm 3 , or approximately 0.6 g / cm³ 3 ~Approx. 0.9g / cm 3 That's fine.

[0140] According to aspects of this disclosure, the present invention provides a sheet or shredded sheet of an aerosolizable material comprising a tobacco material, an aerosol-forming material, and a binder, wherein the sheet or shredded sheet has a density of approximately 0.4 g / cm². 3 An aerosol-generating material having a density of approximately 0.4 g / cm³ is provided. In some embodiments, the density is approximately 0.4 g / cm³. 3 ~Approx. 2.9g / cm 3 Approximately 0.4 g / cm³ 3 ~Approx. 1g / cm 3 , about 0.6g / cm 3 ~Approx. 1.6g / cm 3 , or approximately 1.6 g / cm³ 3 ~Approx. 2.9g / cm 3 That is the case.

[0141] The sheet or shredded sheet may have a tensile strength of at least 4 N / 15 mm.

[0142] If a sheet or shredded sheet has a tensile strength of less than 4 N / 15 mm, the sheet or shredded sheet is prone to tearing, breaking, or other deformation during manufacturing and / or subsequent incorporation into articles for use in non-flammable aerosol supply systems. Tensile strength may be measured using ISO 1924:2008.

[0143] The aerosol-generating material may contain tobacco material. The sheet or shredded sheet of the aerosolizable material may contain tobacco material.

[0144] The tobacco material may be a particle or granular material. In some embodiments, the tobacco material is a powder. Alternatively, or in addition, the tobacco material may include tobacco flakes, strands, or fibers. For example, the tobacco material may include tobacco particles, granules, fibers, flakes, and / or strands. In some embodiments, the tobacco material consists of tobacco particles or granules.

[0145] The density of the tobacco material affects the rate at which heat is conducted through the material. Lower densities, such as less than 900 mg / cc, allow heat to be conducted more slowly through the material, enabling a more sustained release of aerosols.

[0146] The tobacco material may include recycled tobacco material having a density of less than approximately 900 mg / cc, such as recycled paper tobacco material. For example, the aerosol-generating material may include recycled tobacco material having a density of less than approximately 800 mg / cc. Alternatively or in addition, the aerosol-generating material may include recycled tobacco material having a density of at least 350 mg / cc.

[0147] The recycled tobacco material may be provided in the form of shredded sheets. The sheets of recycled tobacco material can have any suitable thickness. The recycled tobacco material can have a thickness of at least about 0.145 mm, for example, at least about 0.15 mm or at least about 0.16 mm. The recycled tobacco material can have a maximum thickness of about 0.30 mm or 0.25 mm, for example, the thickness of the recycled tobacco material may be less than about 0.22 mm or less than about 0.2 mm. In some embodiments, the recycled tobacco material can have an average thickness in the range of 0.175 mm to 0.195 mm.

[0148] In some embodiments, tobacco is a particulate tobacco material. Each particle of the particulate tobacco material may have a maximum dimension. As used herein, the term “maximum dimension” refers to the longest straight-line distance from any point on the surface or particle face of a tobacco particle to any other point on the same surface or particle face of the tobacco particle. The maximum dimension of particles in the particulate tobacco material may be measured using scanning electron microscopy (SEM).

[0149] The maximum size of each particle of the tobacco material may be up to approximately 200 μm. In some embodiments, the maximum size of each particle of the tobacco material is up to approximately 150 μm.

[0150] A collection of tobacco material particles may have a particle size distribution (D90) of at least about 100 μm. In some embodiments, a collection of tobacco material particles may have a particle size distribution (D90) of about 110 μm, at least about 120 μm, at least about 130 μm, at least about 140 μm, or at least about 150 μm. In embodiments, a collection of tobacco material particles may have a particle size distribution (D90) of about 150 μm. Sieve analysis may be used to determine the particle size distribution of the tobacco material particles.

[0151] A particle size distribution of at least approximately 100 μm (D90) is thought to contribute to the tensile strength of a sheet or shredded sheet of aerosolizable material.

[0152] A sheet or shredded sheet of aerosolizable material with a particle size distribution (D90) of less than 100 μm is provided, exhibiting good tensile strength. However, including fine particles of such tobacco material in the sheet or shredded sheet can increase the density of the sheet or shredded sheet. When the sheet or shredded sheet is incorporated into an article for use in a non-combustible aerosol supply system, this higher density can reduce the fill value of the tobacco material. A particle size distribution (D90) of at least about 100 μm is advantageous because it allows for a balance between sufficient tensile strength and appropriate density (and therefore fill value).

[0153] The particle size of the tobacco material can also affect the coarseness of the aerosol-generating material sheet or shredded sheet. It is assumed that incorporating relatively large particles of tobacco material into the formation of the aerosol-generating material sheet or shredded sheet will reduce the density of the aerosol-generating material sheet or shredded sheet.

[0154] The tobacco material may include tobacco obtained from any part of the tobacco plant. In some embodiments, the tobacco material includes tobacco leaves. The sheet or shredded sheet may contain 5% to about 90% by weight of tobacco leaves.

[0155] The tobacco material may include lamina tobacco and / or tobacco stems such as midribone. Lamina tobacco may be present in amounts of 0% to about 100% by weight, about 20% to about 100% by weight, about 40% to about 100% by weight, about 40% to about 95% by weight, about 45% to about 90% by weight, about 50% to about 85% by weight, or about 55% to about 80% by weight of the sheet or shredded sheet and / or tobacco material. In some embodiments, the tobacco material consists of or is essentially composed of lamina tobacco material.

[0156] The tobacco material may contain tobacco stalks in amounts of 0% to approximately 100% by weight, approximately 0% to approximately 50% by weight, approximately 0% to approximately 25% by weight, approximately 0% to approximately 20% by weight, and approximately 5% to approximately 1.5% by weight of the sheet or shredded sheet.

[0157] In some embodiments, the tobacco material includes a combination of lamina and tobacco stalks. In some embodiments, the tobacco material may include about 40% to about 95% by weight of lamina and about 5% to about 60% by weight of stalks in a sheet or shredded sheet of aerosolizable material, or about 60% to about 95% by weight of lamina and about 5% to about 40% by weight of stalks, or about 80% to about 95% by weight of lamina and about 5% to about 20% by weight of stalks.

[0158] Incorporating stems may reduce the tackiness of the aerosolizable material. Incorporating tobacco material, including tobacco stems, into the aerosolizable material may increase its burst strength.

[0159] A sheet or shredded sheet of aerosolizable material can have a burst strength of at least about 75 g, at least about 100 g, or at least about 200 g.

[0160] If the bursting strength is too low, the sheet or shredded sheet may become relatively brittle. As a result, the sheet or shredded sheet may break during the manufacturing process of the aerosolizable material. For example, when a sheet is shredded to form shredded sheets by a cutting process, the sheet may break or crack into pieces or fragments during cutting.

[0161] The tobacco materials described herein may contain nicotine. The nicotine content is 0.1 to 3% by weight of the tobacco material, and may be, for example, 0.5 to 2.5% by weight of the tobacco material. In addition or alternatively, the tobacco material contains 10% to 90% by weight of tobacco leaves, with a nicotine content of more than about 1% by weight or more than about 1.5% by weight of tobacco leaves. Tobacco leaves, for example, shredded rag tobacco, have a nicotine content of, for example, 1% to 5% by weight of tobacco leaves.

[0162] A sheet or shredded sheet of aerosolizable material may contain nicotine in an amount of approximately 0.1% to approximately 3% by weight of the sheet or shredded sheet.

[0163] Recycled tobacco may be present in the aerosol-generating material described herein. Recycled tobacco refers to tobacco material formed by a process in which tobacco raw materials are extracted using a solvent to obtain a residue containing an extract of soluble material and fibrous material, and then (usually after concentration, and optionally after further processing) the extract is remixed with fibrous material from the residue by depositing the extract onto fibrous material (usually after purification of the fibrous material, and optionally with the addition of some non-tobacco fibers). The remixing process is similar to that of papermaking.

[0164] The recycled cigarette may be any type of recycled cigarette known in the art. In certain embodiments, the recycled cigarette is made from raw materials comprising one or more of tobacco flakes, tobacco stalks, and whole tobacco leaves. In further embodiments, the recycled cigarette is made from raw materials comprising tobacco flakes and / or whole tobacco leaves and tobacco stalks. However, in other embodiments, small pieces, powder, and husks may be used as raw materials instead or in addition.

[0165] The recycled cigarettes for use in the tobacco materials described herein may be prepared by methods known to those skilled in the art for preparing recycled cigarettes.

[0166] In the embodiment, recycled cigarettes are present in an amount of 5% to 90% by weight, 10% to 80% by weight, or 20% to 70% by weight of the aerosol-generating material.

[0167] The aerosol-generating material includes an aerosol-forming material. The aerosol-forming material includes one or more components capable of forming an aerosol. The aerosol-forming material includes one or more of the following: glycerin, glycerillol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. The aerosol-forming material is preferably glycerol or propylene glycol.

[0168] A sheet or shredded sheet of aerosolizable material includes an aerosol-forming material. The aerosol-forming material is provided in an amount of up to about 50% by weight of the sheet or shredded sheet on a dry weight basis. In some embodiments, the aerosol-forming material is provided in an amount of about 5% to about 40% by weight of the sheet or shredded sheet on a dry weight basis, about 10% to about 30% by weight of the sheet or shredded sheet on a dry weight basis, or about 10% to about 20% by weight of the sheet or shredded sheet on a dry weight basis.

[0169] The sheet or shredded sheet may also contain water. The sheet or shredded sheet of the aerosolizable material may contain water in an amount of less than about 15% by weight, less than about 10% by weight, or less than about 5% by weight of the aerosolizable material. In some embodiments, the aerosolizable material contains water in an amount of about 0% to about 15% by weight or about 5% to about 15% by weight of the aerosolizable material.

[0170] A sheet or shredded sheet of aerosolizable material may contain water and aerosol-forming material in an amount of less than approximately 30% by weight of the sheet or shredded sheet of aerosolizable material, or less than approximately 25% by weight of the sheet or shredded sheet of aerosolizable material. Incorporating water and aerosol-forming material into a sheet or shredded sheet of aerosolizable material in an amount of less than approximately 30% by weight of the sheet or shredded sheet is considered advantageous because it can reduce the tackiness of the sheet. This can improve the ease with which the aerosolizable material can be handled during processing. For example, it may be easier to roll up a sheet of aerosolizable material to form a bobbin of material, and then unwind the bobbin without the layers of the sheet sticking to each other. Reducing tackiness also reduces the tendency of strands or fragments of shredded material to aggregate or stick to each other, thereby further improving processing efficiency and the quality of the final product.

[0171] The sheet or shredded sheet may contain a binder. The binder is arranged to bind the components of the aerosol-generating material together to form the sheet or shredded sheet. The binder can at least partially coat the surface of the tobacco material. If the tobacco material is particulate, the binder can at least partially coat the surface of the tobacco particles to bind them together.

[0172] The binder may be selected from one or more compounds chosen from the group consisting of alginates, pectin, starch (and derivatives), cellulose (and derivatives), gums, silica or silicone compounds, clay, polyvinyl alcohol, and combinations thereof. For example, in some embodiments, the binder includes one or more of alginates, pectin, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, gum arabic, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the binder includes alginates and / or pectin or carrageenan. In preferred embodiments, the binder includes guar gum.

[0173] The binder may be present in an amount of about 1 to about 20% by weight of the sheet or shredded sheet, or in an amount of 1 to about 10% by weight of the sheet or shredded sheet of the aerosolizable material. For example, the binder may be present in an amount of about 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% by weight of the sheet or shredded sheet of the aerosolizable material.

[0174] Aerosol-generating materials may include fillers. In some embodiments, the sheet or shredded sheet includes a filler. The filler is typically a non-tobacco component, i.e., a component that does not contain tobacco-derived raw materials. The filler may include one or more inorganic filler materials, such as suitable inorganic adsorbents including calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and molecular sieves. The filler may be a non-tobacco fiber such as wood fiber or wood pulp or wheat fiber. The filler may be a cellulose-containing material or a cellulose derivative. The filler component may be a non-tobacco cast material or a non-tobacco extruded material.

[0175] In certain embodiments including a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood, wood pulp, hemp fiber, cellulose, or a cellulose derivative. While we do not wish to be bound by theory, it is thought that including a fibrous filler can increase the tensile strength of the material.

[0176] The filler can also contribute to the texture of the sheet or shredded sheet of the aerosolizable material. For example, a fibrous filler such as wood or wood pulp can provide a sheet or shredded sheet of the aerosolizable material having relatively rough first and second surfaces. Conversely, a non-fibrous particulate filler such as powdered chalk can provide a sheet or shredded sheet of the aerosolizable material having relatively smooth first and second surfaces. In some embodiments, the aerosolizable material includes a combination of different filler materials.

[0177] The filler component may be present in an amount of 0 to 20% by weight of the sheet or shredded sheet, or in an amount of 1 to 10% by weight of the sheet or shredded sheet. In some embodiments, the filler component is absent.

[0178] Fillers can help improve general structural properties of aerosolizable materials, such as tensile strength and burst strength.

[0179] In the compositions described herein, where amounts are expressed in weight percent, to avoid misunderstanding, this refers to dry weight unless otherwise specified. Therefore, any water that may be present in the aerosol-forming material or any of its components is completely disregarded for the purpose of determining the weight percent. The water content of the aerosol-forming material described herein may vary, for example, from 5 to 15% by weight. The water content of the aerosol-forming material described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The water content can be determined by Karl-Fischer analysis, as is known to those skilled in the art. On the other hand, to avoid misunderstanding, any component other than water is included in the weight of the aerosol-forming material, even if the aerosol-forming material is a liquid-phase component such as glycerol or propylene glycol. However, when the aerosol-forming material is supplied to the tobacco component of the aerosol-forming material, or to the filler component of the aerosol-forming material (if present), instead of being added separately to the aerosol-forming material, or in addition to it, the aerosol-forming material is included in the weight of the "aerosol-forming material" in the weight percent as defined herein, but not in the weight of the tobacco component or filler component. Any other ingredients present in the tobacco components, even if they are non-tobacco-derived (e.g., non-tobacco fibers in recycled cigarettes), are included in the weight of the tobacco components.

[0180] The aerosol-generating materials described herein may include aerosol modifiers, such as any of the flavorings described herein. In one embodiment, the aerosol-generating material contains menthol. When the aerosol-generating material is incorporated into an article for use in an aerosol supply system, the article may be called a menthol-containing article. The aerosol-generating material may contain 0.5 mg to 20 mg of menthol, 0.7 mg to 20 mg of menthol, 1 mg to 18 mg, or 8 mg to 16 mg of menthol. In this example, the aerosol-generating material contains 16 mg of menthol. The aerosol-generating material may contain 1% to 8% by weight of menthol, preferably 3% to 7% by weight of menthol, more preferably 4% to 5.5% by weight of menthol. In one embodiment, the aerosol-generating material contains 4.7% by weight of menthol. Such high levels of menthol loading can be achieved by using a high percentage, for example, more than 50% by weight of recycled tobacco material. Alternatively, or in addition, using a large amount of tobacco material, for example, can increase the level of menthol filling that can be achieved, for example, about 500mm 3 For very or preferably approximately 1000 mm 3 Aerosol-generating materials such as tobacco materials are used.

[0181] In some embodiments, the composition includes an aerosol-forming "amorphous solid," which may also be called a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may include a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, inside. In some cases, amorphous solids are 1-60 wt% gelling agent, 0.1-50 wt% aerosol-forming material, Contains 0.1 to 80 wt% fragrance, These weights are calculated on a dry weight basis. In some further embodiments, the amorphous solid is 1-50 wt% gelling agent, 0.1-50 wt% aerosol-forming material, Contains 30-60 wt% fragrance, These weights are calculated on a dry weight basis.

[0182] The amorphous solid material may be provided in the form of a sheet or shredded sheet. As mentioned above, the amorphous solid material may take the same form as the sheet or shredded sheet of the aerosolizable material.

[0183] The amorphous solid is preferably able to contain about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 60 wt%, 50 wt%, 45 wt%, 40 wt%, or 35 wt% of a gelling agent (all calculated on a dry weight basis). For example, the amorphous solid may contain 1 to 50 wt%, 5 to 45 wt%, 10 to 40 wt%, or 20 to 35 wt% of a gelling agent. In some embodiments, the gelling agent includes a hydrophilic colloid. In some embodiments, the gelling agent includes one or more compounds selected from the group including alginates, pectin, starch (and derivatives), cellulose (and derivatives), gum, silica or silicone compounds, clay, polyvinyl alcohol, and combinations thereof. For example, in some embodiments, the gelling agent includes one or more of alginates, pectin, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, pullulan, xanthan gum, guar gum, carrageenan, agarose, acacia gum, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the gelling agent includes alginates and / or pectin and may be mixed with a curing agent (such as a calcium source) during the formation of the amorphous solid. In some cases, the amorphous solid may include calcium crosslinked alginates and / or calcium crosslinked pectin.

[0184] In some embodiments, the gelling agent comprises an alginate, which is present in the amorphous solid in an amount of 10-30 wt% (calculated on a dry weight basis). In some embodiments, the alginate is the only gelling agent present in the amorphous solid. In other embodiments, the gelling agent comprises an alginate and at least one further gelling agent, such as pectin.

[0185] In some embodiments, the amorphous solid may contain a gelling agent including carrageenan.

[0186] The amorphous solid is preferably able to contain about 0.1 wt%, 0.5 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, or 10% to about 50 wt%, 45 wt%, 40 wt%, 35 wt%, 30 wt%, or 25 wt% of aerosol-forming material (all calculated on a dry weight basis). The aerosol-forming material can act as a plasticizer. For example, the amorphous solid may contain 0.5 to 40 wt%, 3 to 35 wt%, or 10 to 25 wt% of aerosol-forming material. In some cases, the aerosol-forming material may include one or more compounds selected from erythritol, propylene glycol, glycerol, triacetin, sorbitol, and xylitol. In some cases, the aerosol-forming material may contain glycerol, be essentially composed of glycerol, or be composed of glycerol.

[0187] The amorphous solid contains fragrance. Preferably, the amorphous solid can contain up to approximately 80 wt%, 70 wt%, 60 wt%, 55 wt%, 50 wt%, or 45 wt% of fragrance.

[0188] In some cases, amorphous solids may contain at least approximately 0.1 wt%, 1 wt%, 10 wt%, 20 wt%, 30 wt%, 35 wt%, or 40 wt% of fragrance (all calculated on a dry weight basis).

[0189] For example, an amorphous solid may contain 1-80 wt%, 10-80 wt%, 20-70 wt%, 30-60 wt%, 35-55 wt%, or 30-45 wt% of flavoring. In some cases, the flavoring may contain menthol, be essentially composed of menthol, or be composed of menthol.

[0190] In some cases, the amorphous solid may further contain an emulsifier that emulsifies the molten fragrance during manufacturing. For example, the amorphous solid may contain about 5 wt% to about 15 wt%, preferably about 10 wt%, of emulsifier (calculated on a dry weight basis). The emulsifier may include gum arabic.

[0191] In some embodiments, the amorphous solid is a hydrogel containing less than about 20 wt% water on a wet weight basis. In some cases, the hydrogel may contain less than about 15 wt%, 12 wt%, or 10 wt% water on a wet weight basis. In some cases, the hydrogel may contain at least about 1 wt%, 2 wt%, or at least about 5 wt% water (on a wet weight basis).

[0192] In some embodiments, the amorphous solid further comprises an active substance. For example, in some cases, the amorphous solid further comprises tobacco material and / or nicotine. In some cases, the amorphous solid may contain 5 to 60 wt% (calculated on a dry weight basis) of tobacco material and / or nicotine. In some cases, the amorphous solid may contain about 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to about 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (calculated on a dry weight basis) of the active substance. In some cases, amorphous solids can contain approximately 1 wt%, 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to approximately 70 wt%, 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (calculated on a dry weight basis) of tobacco material. For example, amorphous solids can contain 10-50 wt%, 15-40 wt%, or 20-35 wt% of tobacco material. In some cases, amorphous solids can contain approximately 1 wt%, 2 wt%, 3 wt%, or 4 wt% to approximately 20 wt%, 18 wt%, 15 wt%, or 12 wt% of nicotine (calculated on a dry weight basis). For example, amorphous solids can contain 1-20 wt%, 2-18 wt%, or 3-12 wt% of nicotine.

[0193] In some cases, amorphous solids contain active substances such as tobacco extract. In some cases, amorphous solids may contain 5-60 wt% (calculated on a dry weight basis) of tobacco extract. In some cases, amorphous solids may contain approximately 5 wt%, 10 wt%, 15 wt%, 20 wt%, or 25 wt% to approximately 60 wt%, 50 wt%, 45 wt%, 40 wt%, 35 wt%, or 30 wt% (calculated on a dry weight basis) of tobacco extract. For example, amorphous solids may contain 10-50 wt%, 15-40 wt%, or 20-35 wt% of tobacco extract. Tobacco extracts may contain nicotine at concentrations such that the amorphous solid contains 1 wt%, 1.5 wt%, 2 wt%, or 2.5 wt% to approximately 6 wt%, 5 wt%, 4.5 wt%, or 4 wt% (calculated on a dry weight basis) of nicotine.

[0194] In some cases, nicotine other than that obtained from tobacco extract may not be present in the amorphous solid.

[0195] In some embodiments, the amorphous solid does not contain tobacco material but contains nicotine. In some such cases, the amorphous solid may contain about 1 wt%, 2 wt%, 3 wt%, or 4 wt% to about 20 wt%, 18 wt%, 15 wt%, or 12 wt% of nicotine (calculated on a dry weight basis). For example, the amorphous solid may contain 1 to 20 wt%, 2 to 18 wt%, or 3 to 12 wt% of nicotine.

[0196] In some cases, the total content of active substances and / or fragrances may be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active substances and / or fragrances may be less than about 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all calculated on a dry weight basis).

[0197] In some cases, the total content of tobacco materials, nicotine, and flavorings may be at least about 0.1 wt%, 1 wt%, 5 wt%, 10 wt%, 20 wt%, 25 wt%, or 30 wt%. In some cases, the total content of active substances and / or flavorings may be less than about 90 wt%, 80 wt%, 70 wt%, 60 wt%, 50 wt%, or 40 wt% (all calculated on a dry weight basis).

[0198] The amorphous solid may be prepared from a gel, which may further contain a solvent in an amount of 0.1 to 50 wt%. However, including a solvent in which the fragrance dissolves may reduce the stability of the gel, and the fragrance may crystallize from the gel. Therefore, in some cases, the gel does not contain a solvent in which the fragrance dissolves.

[0199] In some embodiments, the amorphous solid contains less than 60 wt% of filler, for example, 1 wt% to 60 wt%, or 5 wt% to 50 wt%, or 5 wt% to 30 wt%, or 10 wt% to 20 wt%.

[0200] In other embodiments, the amorphous solid contains less than 20 wt%, preferably less than 10 wt%, or less than 5 wt% of filler. In some cases, the amorphous solid contains less than 1 wt% of filler, and in some cases, it contains no filler at all.

[0201] If a filler is present, the filler may include one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents such as molecular sieves. The filler may also include one or more organic filler materials, such as wood pulp, cellulose, and cellulose derivatives. In certain cases, the amorphous solid does not contain calcium carbonate, such as chalk.

[0202] In certain embodiments including a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood pulp, hemp fiber, cellulose, or a cellulose derivative. While we do not wish to be bound by theory, it is thought that including a fibrous filler in an amorphous solid can increase the tensile strength of the material.

[0203] In some embodiments, the amorphous solid does not contain tobacco fibers.

[0204] In some examples, amorphous solids in sheet form can have tensile strengths of about 200 N / m to about 1500 N / m. In some examples where the amorphous solid does not contain fillers, the amorphous solid can have tensile strengths of 200 N / m to 400 N / m, or 200 N / m to 300 N / m, or about 250 N / m. Such tensile strengths may be particularly suitable for embodiments in which the amorphous solid material is formed as a sheet, then shredded, and incorporated into an aerosol product.

[0205] In some examples where the amorphous solid contains a filler, the amorphous solid can have a tensile strength of 600 N / m to 1500 N / m, or 700 N / m to 900 N / m, or about 800 N / m. Such tensile strengths may be particularly suitable for embodiments in which the amorphous solid material is included in an aerosol product as a rolled sheet, preferably in the form of a tube.

[0206] In some cases, the amorphous solid may be essentially composed of, or composed of, a gelling agent, water, an aerosol-forming material, a fragrance, and optionally, an active substance.

[0207] In some cases, the amorphous solid may be essentially composed of, or composed of, a gelling agent, water, an aerosol-forming material, a flavoring, and optionally, tobacco material and / or a nicotine source.

[0208] The amorphous solid may contain one or more active substances and / or fragrances, one or more aerosol-forming materials, and optionally one or more other functional materials.

[0209] The aerosol-forming material may include recycled tobacco material. The composition may, instead or in addition, include any of the forms of tobacco described herein. The aerosol-forming material may comprise a sheet or shredded sheet containing tobacco material comprising 10% to 90% by weight of tobacco leaves, wherein the aerosol-forming material is provided in an amount of up to about 20% by weight of the sheet or shredded sheet, and the remaining portion of the tobacco material comprises recycled tobacco.

[0210] If the aerosol-generating material includes an amorphous solid material, the amorphous solid material may be a dry gel containing menthol. In alternative embodiments, the amorphous solid may have any of the compositions described herein.

[0211] An improved article can be manufactured comprising an aerosol-generating material comprising a first component comprising a sheet or shredded sheet of an aerosolizable material and a second component comprising an amorphous solid, wherein the material properties (e.g., density) and specifications (e.g., thickness, length, and cutting width) are within the range described herein.

[0212] In some cases, the amorphous solid can have a thickness of about 0.015 mm to about 1.0 mm. Preferably, the thickness may be in the range of about 0.05 mm, 0.1 mm, or 0.15 mm to about 0.5 mm or 0.3 mm. Materials having a thickness of about 0.09 mm can be used. The amorphous solid may consist of two or more layers, and the thicknesses described herein refer to the total thickness of these layers.

[0213] The thickness of amorphous solid materials can be measured using a microscope such as a caliper or scanning electron microscope (SEM), as is known to those skilled in the art, or any other suitable technique known to those skilled in the art.

[0214] If the amorphous solid is too thick, heating efficiency may decrease. This can negatively affect power consumption during use, for example, the power consumption required to release fragrance from the amorphous solid. Conversely, if the amorphous solid for aerosol formation is too thin, it may be difficult to manufacture and handle. Very thin materials are more difficult to cast, are brittle, and may hinder aerosol formation during use. In some cases, individual pieces or sections of amorphous solid have a minimum thickness of about 0.015 mm over their area. In some cases, individual pieces or sections of amorphous solid have a minimum thickness of about 0.05 mm or about 0.1 mm over their area. In some cases, individual pieces or sections of amorphous solid have a maximum thickness of about 1.0 mm over their area. In some cases, individual pieces or sections of amorphous solid have a maximum thickness of about 0.5 mm or about 0.3 mm over their area.

[0215] In some cases, the thickness of an amorphous solid can vary by 25%, 20%, 15%, 10%, 5%, or less than 1% across its area.

[0216] By providing sheets or shredded sheets of amorphous solid material and aerosolizable material having different surface density values ​​below a given percentage, the mixture of these materials becomes less likely to separate. In some examples, the surface density of the amorphous solid material may be 50% to 150% of the surface density of the aerosolizable material. For example, the surface density of the amorphous solid material may be 60% to 140% of the surface density of the aerosolizable material, or 70% to 110%, or 80% to 120% of the surface density of the aerosolizable material.

[0217] In the embodiments described herein, amorphous solid materials can be incorporated into articles in the form of sheets. Preferably, amorphous solid materials in sheet form can be incorporated into articles after being shredded, and can be mixed with aerosolizable materials such as sheets or shredded sheets of aerosolizable materials described herein.

[0218] In further embodiments, amorphous solid sheets may be incorporated as planar sheets, collected or bundled sheets, crimped sheets, or rolled sheets (i.e., in the form of tubes). In some such cases, the amorphous solids of these embodiments may be included in the aerosol product as sheets, such as sheets surrounding a rod containing the aerosolizable material. For example, an amorphous solid sheet may be formed in a roll of paper surrounding an aerosolizable material such as a cigarette.

[0219] The amorphous solid in sheet form weighs approximately 30 g / m². 2 ~about 150g / m 2 It can have any suitable surface density, such as 55 g / m². In some cases, the sheet may have a density of approximately 55 g / m². 2 ~Approx. 135g / m 2 , or approximately 80-120g / m 2 , or approximately 70-110 g / m 2 , or especially about 90-110 g / m² 2 , or preferably about 100 g / m²2 It can have a unit area mass of approximately 30-70 g / m². These ranges can provide densities similar to those of shredded rag tobacco, and as a result, can provide a mixture of these materials that is less prone to separation. Such surface densities may be particularly suitable when amorphous solid materials are included in the aerosol product as shredded sheets (as further described below). In some cases, the sheets may have a density of approximately 30-70 g / m². 2 40-60g / m 2 , or 25-60g / m 2 It can have a unit area mass of and can be used to wrap aerosolizable materials such as the aerosolizable materials described herein.

[0220] The aerosol-generating material may include a mixture of the aerosolizable material described herein and an amorphous solid material. Such an aerosol-generating material can be made to which additional fragrances can be introduced by including them in the amorphous solid material component, thereby providing a desirable fragrance profile to the aerosol during use. Since the fragrances provided in the amorphous solid material can be retained more stably within the amorphous solid material compared to fragrances added directly to the tobacco material, a more consistent fragrance profile can be obtained between articles manufactured according to this disclosure.

[0221] As mentioned above, tobacco materials having a density of at least 350 mg / cc to less than about 900 mg / cc, preferably about 600 mg / cc to about 900 mg / cc, have been found to be advantageous as they lead to more sustained aerosol release. In order to provide an aerosol with a consistent flavor profile, the amorphous solid material components of the aerosol-generating material should be uniformly dispersed throughout the rod. This can be achieved by casting the amorphous solid material to provide an amorphous solid material having the thickness described herein and a surface density similar to that of the tobacco material, and by processing the amorphous solid material as described below to ensure uniform dispersion throughout the aerosol-generating material.

[0222] As mentioned above, optionally, the aerosol-generating material comprises multiple fragments of an amorphous solid material. If the aerosol-generating portion comprises multiple strands and / or fragments of a sheet of aerosolizable material and multiple fragments of an amorphous solid material, the material properties and / or dimensions of at least two of these components may be appropriately selected in other ways to ensure that relatively uniform mixing of the components is possible and to reduce separation or unmixing of the components during or after the manufacture of the rod of the aerosol-generating material.

[0223] The longitudinal dimensions of the multiple strands or flakes may be approximately the same as the length of the aerosol-generating portion. The multiple strands and / or flakes may have a length of at least about 5 mm.

[0224] Figure 3 shows a simplified representation of the components of an embodiment of the non-combustible aerosol supply device 100. In particular, the elements of the non-combustible aerosol supply device 100 in Figure 3 are not depicted to scale. To simplify Figure 3, elements not relevant to understanding this embodiment have been omitted.

[0225] As shown in Figure 3, the non-combustible aerosol supply device 100 is a non-combustible aerosol supply device having a housing 101 with a region 102 for receiving article 1.

[0226] Region 102 is positioned to receive article 1. When article 1 is received in region 102, at least a portion of the aerosol-generating material is thermally close to the heater 103. When article 1 is fully received in region 102, at least a portion of the aerosol-generating material can come into direct contact with the heater 103. The aerosol-forming substrate releases various volatile compounds at different temperatures. By controlling the maximum operating temperature of the electrically heated aerosol-generating system 100, the selective release of undesirable compounds can be controlled by preventing the release of selected volatile compounds.

[0227] As shown in Figure 4, an electrical energy source 104, such as a rechargeable lithium-ion battery, is located within the housing 101. A controller 105 is connected to the heater 103, the electrical energy source 104, and a user interface 106, such as buttons or a display. The controller 105 controls the power supplied to the heater 103 to adjust its temperature. Typically, the aerosol-forming substrate is heated to a temperature of 250-450 degrees Celsius.

[0228] Figure 5 is a schematic cross-sectional view of a non-combustible aerosol supply device of the type shown in Figure 3, in which a heater 103 is inserted into the aerosol-generating material 3 of article 1. The non-combustible aerosol supply device is shown engaged with the aerosol product 1 for the user to consume the aerosol product 1.

[0229] The housing 101 of the non-flammable aerosol supply device defines a region 102 in the form of a cavity that opens at its proximal end (or mouth end) for receiving the aerosol product 1 to be consumed. A heating assembly including a heater 103 is mounted at the distal end of the cavity. The heater 103 is held by a heater mounting base (not shown) such that the active heating region of the heater is located within the cavity. When the aerosol product 1 is fully received within the cavity, the active heating region of the heater 103 is located within the aerosol-generating portion of the aerosol product 1.

[0230] The heater 103 is configured to be inserted into the aerosol-generating material 3. The heater 103 is formed in the shape of a blade that terminates at its tip. That is, the length dimension of the heater is greater than its width dimension, and the width dimension is greater than its thickness dimension. The first and second surfaces of the heater are defined by the width and length of the heater.

[0231] When article 1 is pushed into the cavity, the tapered tip of the heater engages with the aerosol-generating material 3. The blade is formed to be easily inserted and removed from the aerosol-generating material 3. By applying force to article 1, the heater penetrates the aerosol-generating material 3. When article 1 is properly engaged with the non-flammable aerosol supply device, the heater 103 is inserted into the aerosol-generating material 3. When the heater is activated, the aerosol-generating material 3 is heated, and volatile substances are generated or released. When the user inhales through the mouthpiece 2, air is drawn into article 1, and the volatile substances condense to form an inhalable aerosol. This aerosol enters the user's mouth through the mouthpiece 2 of article 1.

[0232] The aerosol generating material 3 shown in Figure 5 has two heat transfer fibers 40 within it. These fibers transfer heat received from the heater 103 to other areas of the aerosol generating material 3, thereby achieving a more uniform heat distribution.

[0233] In general, the heat transfer materials of this disclosure help distribute heat through aerosol-generating materials. This allows for a more uniform heat distribution and avoids localized hot spots.

[0234] In some embodiments, the heat transfer material is nonmetallic. Such materials can have the advantage of being relatively lightweight and having a low thermal mass. Therefore, such materials do not significantly add weight to the article and are more efficient in transferring heat from one area to another.

[0235] The combination of a metal heating element and a non-metallic heat transfer material such as graphite is considered to be an advantageous combination for achieving a heat distribution through aerosol-generating materials.

[0236] The various embodiments described herein are presented solely to aid in the understanding and teaching of the claimed features. These embodiments are presented merely as representative examples of the embodiments and are not comprehensive and / or exclusive. The advantages, embodiments, examples, functions, features, structures, and / or other aspects described herein should not be considered to limit the scope of the invention as defined in the claims or to equivalents thereof, and it should be understood that modifications may be made using other embodiments without departing from the scope of the claimed invention.
