Description

[Technical Field]

[0001] The following relates to components used in non-combustible aerosol supply systems, articles used in conjunction with non-combustible aerosol supply devices, and methods for manufacturing components used in non-combustible aerosol supply systems. [Background technology]

[0002] Certain tobacco industry products generate aerosols during use, which are then inhaled by the user. For example, a tobacco heating device heats an aerosol-generating substrate such as tobacco, forming an aerosol through heating rather than combustion. Such tobacco industry products may be equipped with a mouthpiece through which the aerosol passes and reaches the user's mouth. [Overview of the project]

[0003] According to some embodiments described herein, in a first embodiment, a component is provided for use in a non-combustible aerosol supply system, comprising an inner body comprising a first material and an outer body comprising a second material and surrounding the inner body. The resistance to gas flow in the longitudinal direction of the inner body is less than the resistance to gas flow in the longitudinal direction of the outer body.

[0004] According to some embodiments described herein, a second embodiment provides an article for use with a non-combustible aerosol supply device, comprising an aerosol generating material including at least one aerosol-forming material, and a component according to the first embodiment.

[0005] According to some embodiments described herein, a third embodiment provides a method for manufacturing a component for use in a non-combustible aerosol supply system, comprising the steps of forming an inner body and forming an outer body surrounding the inner body. The resistance to gas flow in the longitudinal direction of the inner body is less than the resistance to gas flow in the longitudinal direction of the outer body.

[0006] According to some embodiments described herein, a non-combustible aerosol supply system is provided, comprising an article according to a second embodiment and a non-combustible aerosol supply device.

[0009] As used herein, the term "delivery system" is intended to include a system for delivering at least one substance to a user. combustible aerosol supply systems such as cigarettes, cigarillos, cigars, and pipe tobacco or tobacco for roll-your-own or home-made cigarettes, etc. (regardless of whether they are based on tobacco, tobacco derivatives, extended tobacco, recycled tobacco, tobacco substitutes, or other smoking materials), non-combustible aerosol supply systems that release compounds from aerosol-generating materials without combustion (such as e-cigarettes, tobacco heating products, and hybrid systems that generate aerosols by combining aerosol-generating materials), aerosol-free delivery systems that deliver at least one substance to a user orally, nasally, transdermally, or by another method without forming an aerosol (including products such as lozenges, gums, patches, articles containing inhalable powders, and oral products such as oral tobacco containing snus or moist snuff, but not limited to these) (the at least one substance may or may not contain nicotine), and the like.

[0010] According to the present disclosure, a "combustible" aerosol supply system is one in which the aerosol-generating material (or its components), which is a constituent of the aerosol supply system, is burned or ignited during use to facilitate the delivery of at least one substance to a user.

[0011] According to the present disclosure, a "non-combustible" aerosol supply system is one in which the aerosol-generating material (or its components), which is a constituent of the aerosol supply system, is not burned or ignited during use to facilitate the delivery of at least one substance to a user.

[0012] In the embodiments described herein, the delivery system is a non-combustible aerosol supply system such as a power supply non-combustible aerosol supply system.

[0013] In some embodiments, the non-combustible aerosol supply system is an electronic cigarette, also known as a vaping device or an electronic nicotine delivery system (END), but it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0014] In some embodiments, the non-combustible aerosol supply system is an aerosol-generating material heating system, also known as a non-combustion heating system. An example of such a system is a tobacco heating system.

[0015] In one embodiment, the non-combustible aerosol supply system is a hybrid system that generates an aerosol by a combination of aerosolizable materials (one or more of which may be configured to be heated). Each aerosolizable material may be in the form of, for example, a solid, liquid, or gel, and may or may not contain nicotine. In one embodiment, the hybrid system includes a liquid or gel aerosolizable material and a solid aerosolizable material. The solid aerosolizable material may include, for example, tobacco or non-tobacco products.

[0016] Typically, the non-combustible aerosol supply system may include a non-combustible aerosol supply device and a consumable used with the non-combustible aerosol supply device.

[0017] In some embodiments, the present disclosure relates to a consumable that includes an aerosol-generating material and is configured to be used with a non-combustible aerosol supply device. Throughout the present disclosure, these consumables may sometimes be referred to as articles.

[0018] Consumables are articles containing aerosol-generating material or articles consisting of aerosol-generating material, which are intended to be consumed in whole or in part by the user during use. Consumables may also comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transport component, an aerosol-generating area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. Consumables may also comprise an aerosol generator, such as a heater, which releases heat during use to generate an aerosol from the aerosol-generating material. The heater may include, for example, a flammable material, an electrically conductive material, or a susceptor.

[0019] In some embodiments, the non-combustible aerosol supply system (including the non-combustible aerosol supply device) may include a power source and a control device. The power source may be, for example, an electrical power source or a heat-generating power source. In some embodiments, the heat-generating power source includes a carbon substrate capable of supplying energy to an aerosol-generating material or heat-transferring material adjacent to the heat-generating power source, supplying power in the form of heat.

[0020] In some embodiments, the non-combustible aerosol supply system may include a consumable receiving area, an aerosol generator, an aerosol generating area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0021] In some embodiments, consumables used with a non-combustible aerosol supply device may include aerosol generating material, an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generator, an aerosol generating area, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.

[0022] In some embodiments, the delivered substance may be an aerosol-generating material or a material that is not subject to aerosolization. Either material may optionally contain one or more active components, one or more fragrances, one or more aerosol-forming materials, and / or one or more other functional materials.

[0023] 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 form an aerosol by applying thermal energy to the aerosol-generating material, thereby causing one or more volatile substances to be released from the aerosol-generating material. 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.

[0024] Aerosol-generating material is a material capable of generating an aerosol when energy is supplied, for example, by heating, irradiation, or any other method. The aerosol-generating material may be in the form of a solid, liquid, or gel, and may or may not contain active substances and / or flavorings. In some embodiments, the aerosol-generating material may include an "amorphous solid," which may be alternatively referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. The amorphous solid is a solid material capable of holding some fluid, such as a liquid, internally. In some embodiments, the aerosol-generating material may include, for example, about 50 wt%, 60 wt%, or 70 wt% to about 90 wt%, 95 wt%, or 100 wt% of an amorphous solid.

[0025] The aerosol-generating material may include one or more active substances and / or fragrances, one or more aerosol-forming materials, and optionally one or more other functional materials.

[0026] The aerosol-forming material may contain one or more constituent substances capable of forming an aerosol. In some embodiments, the aerosol-forming material may contain one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl sulfate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0027] One or more other functional materials may include one or more of the following: pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0028] The material may be present on or within the support to form the base material. The support may be, for example, paper, cardboard, paperboard, thick paper, recycled material, plastic material, ceramic material, composite material, glass, metal, or alloy, or may contain these materials. In some embodiments, the support includes a susceptor. In some embodiments, the susceptor is embedded in the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

[0029] Aerosol modifiers are typically located downstream of the aerosol generation area and are configured to modify the generated aerosol by altering, for example, the flavor, taste, acidity, or other properties of the aerosol. The aerosol modifier may be contained within an aerosol modifier release component that is operable to selectively release the aerosol modifier.

[0030] The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may contain, for example, one or more of the following: 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 powder, thread, or granular form. The aerosol modifier may not have a filter material.

[0031] A susceptor is a material that can be heated by the intrusion of a fluctuating magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material so that induction heating of the heating material occurs upon intrusion of the fluctuating magnetic field. The heating material may be a magnetic material so that magnetic hysteresis heating of the heating material occurs upon intrusion of the fluctuating magnetic field. The susceptor may have both conductive and magnetic properties so that it can be heated by both heating mechanisms. In this specification, a device configured to generate a fluctuating magnetic field is referred to as a magnetic field generator.

[0032] Induction heating is the process by which a conductive object is heated by the penetration of a fluctuating magnetic field. This process is described by Faraday's law of induction and Ohm's law. An induction heater may comprise an electromagnet and a device that allows a fluctuating current, such as an alternating current, to pass through the electromagnet. When the electromagnet and the object to be heated are preferably positioned relative to each other so that the resulting fluctuating magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated inside the object. The object has resistance to the flow of current. Therefore, when such eddy currents are generated in an object, the object is heated by the flow against its electrical resistance. This process is called Joule heating, Ohmian heating, or resistance heating. An object that can be inductively heated is known as a susceptor.

[0033] In one embodiment, the susceptor is in the form of a closed circuit. It has been found that when the susceptor is in the form of a closed circuit, the magnetic coupling between the susceptor and the electromagnet during use is enhanced, thereby increasing or improving Joule heating.

[0034] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by the penetration of a fluctuating magnetic field. Magnetic materials are thought to contain many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles become aligned with the magnetic field. Therefore, when a fluctuating magnetic field, such as an alternating magnetic field generated by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes in response to the application of the fluctuating magnetic field. This reorientation of magnetic dipoles generates heat within the magnetic material.

[0035] If an object is both conductive and magnetic, both Joule heating and magnetic hysteresis heating can occur within the object due to the penetration of a fluctuating magnetic field. Furthermore, the use of magnetic materials can increase the magnetic field strength, which can amplify Joule heating.

[0036] In each of the above processes, heat is generated within the object itself rather than from an external heat source. Therefore, by selecting suitable object materials and shapes, as well as suitable magnitudes and orientations of the fluctuating magnetic field, rapid heating and a more uniform heat distribution can be achieved within the object. Furthermore, since induction heating and magnetic hysteresis heating do not require a physical connection between the fluctuating magnetic field source and the object, the design flexibility and control of the heating profile are increased, and costs may be reduced.

[0037] Items (for example, rod-shaped items) are often named according to their length ("Regular" (usually in the range of 68-75mm (e.g., approximately 68mm-72mm)), "Short" or "Mini" (68mm or less), "King Size" (usually in the range of 75-91mm (e.g., approximately 79mm-88mm)), "Long" or "Super King" (usually in the range of 91-105mm (e.g., approximately 94mm-101mm)), and "Ultra Long" (usually in the range of approximately 110mm-121mm)).

[0038] Furthermore, these are named according to the product's circumference ("Regular" (approx. 23-25mm), "Wide" (over 25mm), "Slim" (approx. 22-23mm), "Demi-Slim" (approx. 19-22mm), "Super-Slim" (approx. 16-19mm), "Micro-Slim" (less than 16mm)).

[0039] Therefore, a king-size super-slim item would, for example, have a length of approximately 83 mm and a circumference of approximately 17 mm.

[0040] Each type may be produced with mouthpieces of different lengths. The length of the mouthpieces will be approximately 30 mm to 50 mm. The tip paper will be longer than the mouthpiece (e.g., 3 to 10 mm) so as to connect the mouthpiece to the aerosol-generating material, and typically cover the mouthpiece and overlap the aerosol-generating material (e.g., in the form of a rod of base material), connecting the mouthpiece to the rod.

[0041] The articles described herein, as well as their respective aerosol-generating materials and mouthpieces, may be constructed in any of the above-described forms, but are not limited thereto.

[0042] As used herein, the terms "upstream" and "downstream" are relative terms defined with respect to the direction of the mainstream aerosol drawn through the article or device during use.

[0043] The filament tow described herein may include cellulose acetate fiber tow. The filament tow can also be formed using other materials used for fiber formation, 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 with a tow-suitable plasticizer (triacetin in the case of cellulose acetate tow), or the tow may be unplasticized. The tow may have any preferred specifications, such as the fibers having a "Y," "X," or "O" shaped cross-section. The tow fibers may have a filament denier value of 2.5 to 15 denier per filament (for example, 8.0 to 11.0 denier per filament), and a total denier value of 5,000 to 50,000 (for example, 10,000 to 40,000). The cross-section of the fiber has an isoperimetric ratio L 2 / A may be 25 or less, 20 or less, or 15 or less (where L is the perimeter of the cross-section and A is the area of ​​the cross-section). Such fibers have a relatively small surface area relative to a given denier value per filament, improving aerosol delivery to the consumer. The filter materials described herein also include cellulose-based materials such as paper. Such materials may have a relatively low density, such as about 0.1 to about 0.45 grams per cubic centimeter, so that air and / or aerosols can pass through the material. Although described as filter materials, such materials may have primary purposes unrelated to their original purpose, such as increasing resistance to component extraction.

[0044] In this specification, the term "tobacco material" refers to any material including tobacco or its derivatives or substitutes. The term "tobacco material" may include one or more of tobacco, tobacco derivatives, extended tobacco, remanufactured tobacco, or tobacco substitutes. Tobacco material may include one or more of ground tobacco, tobacco fibers, loose tobacco, extruded tobacco, tobacco stems, tobacco laminas, remanufactured tobacco, and / or tobacco extracts.

[0056] In the drawings described herein, the same reference numerals are used to indicate equivalent features, articles, or components.

[0057] Figure 1a is a lateral cross-sectional view of a component used in a non-combustible aerosol supply system. In this example and other examples described herein, the component is a component of a non-combustible aerosol supply system (e.g., a component of a tobacco heating product). Figure 1b is an end cross-sectional view of the component shown in Figure 1a, passing through the line A-A'.

[0058] Component 10 comprises an inner body 11 and an outer body 12 surrounding the inner body. The inner body 11 contains a first material, and the outer body 12 contains a second material. The resistance of the inner body 11 to gas flow in the longitudinal direction is less than the resistance of the outer body 12 to gas flow in the longitudinal direction. With this configuration, more gas flow can pass through the inner body 11 than through the outer body 12. As a result, the aerosol generated by the non-combustible aerosol supply system during use is kept away from the user's lips.

[0059] In some examples, component 10 may be a mouthpiece for an article used with a non-combustible aerosol supply device. This will be explained in more detail below in relation to Figure 2.

[0060] In some cases, the resistance to gas flow in the longitudinal direction of the inner body 11 (i.e., pressure drop) is less than approximately 30 mmH2O. It has been found that such a pressure drop allows sufficient aerosol (containing desirable components such as flavor components) to pass through the inner body 11 and reach the user. In some cases, the resistance to gas flow in the longitudinal direction of the inner body 11 is less than approximately 25 mmH2O.

[0061] As an alternative or addition, the resistance to gas flow in the longitudinal direction of the inner body 11 can be at least 10 mmH2O, at least 15 mmH2O in some examples, and at least 20 mmH2O in some examples. In some examples, the resistance to gas flow in the longitudinal direction of the inner body 11 can be approximately 5 mmH2O to 30 mmH2O.

[0062] The resistance to gas flow in the longitudinal direction of the outer body 12 can be at least 50 mmH2O, at least 55 mmH2O in some examples, and at least 60 mmH2O in some examples. In some examples, the resistance to gas flow in the longitudinal direction of the inner body 11 can be approximately 40 mmH2O to 60 mmH2O.

[0063] In this example, the inner body 11 is cylindrical and the outer body 12 is tubular. The tubular outer body 12 includes a hollow cavity extending through it. The inner body 11 is disposed within the cavity of the outer body 12 such that the outer body 12 surrounds the inner body 11. In this example, the inner body 11 and the outer body 12 are substantially the same length, and their longitudinal end faces are coplanar. The inner body 11 and the outer body 12 share a common longitudinal axis.

[0064] In this example, the inner body 11 and the outer body 12 are integrally formed as a single material body. In some examples, the inner body and the outer body are formed as separate material bodies that are integrally fixed together, for example, by adhesive.

[0065] In some examples, the inner body 11 and / or outer body 12 may be formed of filament tow such as cellulose acetate tow. The density of the filament tow constituting the inner body 11 is lower than the density of the filament tow constituting the outer body 12. Therefore, the resistance of the inner body 11 to gas flow in the longitudinal direction is smaller than the resistance of the outer body 12 to gas flow in the longitudinal direction. The density of the filament tow can be adjusted by selecting the total denier of the filament tow for a given cross-sectional area. This will be explained in more detail below.

[0066] In this example, both the inner body 11 and the outer body 12 are formed from plasticized cellulose acetate tow. In other examples, the inner body 11 and / or the outer body 12 may be formed from tow other than cellulose acetate (e.g., polylactic acid (PLA), other materials described herein with respect to filament tow, filter materials, or similar materials).

[0067] In some examples, the density of the material constituting the inner body 11 is at least about 0.1 grams / cm³ (g / cc), and in some examples, at least about 0.15 g / cc. In some examples, the density of the material constituting the inner body 11 is less than about 0.2 grams / cm³ (g / cc), and in some examples, less than 0.25 g / cc. In some examples, the density of the material constituting the inner body 11 is between 0.1 and 0.25 g / cc, and in some examples, between 0.1 g / cc and 0.15 g / cc or between 0.15 g / cc and 0.2 g / cc. These densities have been shown to provide a good balance between the improved hardness of high-density materials and the low heat transfer properties of low-density materials. In examples where the inner body is formed by filament tows, the "density" of the inner body 11 represents the density of the filament tows constituting the body into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the inner body 11 by the total volume of the inner body 11.

[0068] In this example, the tow used for the inner body 11 has a denier per filament (dpf) of 8.4 and a total denier of 7,500. The plasticizer used in this tow constitutes approximately 7% by weight of the tow. In this example, the plasticizer is triacetin. In some examples, the tow has a dpf of at least 5, at least 6 in some examples, and at least 7 in some examples, regardless of whether it is formed from cellulose acetate or other materials. These denier per filament values ​​result in a tow with a smaller surface area and relatively coarse, thicker fibers, which in turn reduces the pressure drop throughout the inner body 11 compared to tows with lower dpf values. To achieve a sufficiently uniform material body 11, the tow has a denier per filament of 12 dpf or less, at least 11 dpf in some examples, and at least 10 dpf in some examples.

[0069] In some examples, the total denier of the tow constituting the inner body 11 is up to 11,000, up to 10,000 in some examples, and up to 9,000 in others. These total denier values ​​result in a reduced proportion of the tow to the cross-sectional area of ​​the inner body 11, which in turn reduces the pressure drop across the entire inner body 11 compared to tows with higher total denier values. To give the inner body 11 a suitable stiffness, the tow has a total denier of at least 3,000, and up to 4,000 in some examples. In some examples, the denier per filament is 5 to 12, while the total denier is 3,000 to 9,000. In some examples, the denier per filament is 6 to 10, while the total denier is 4,000 to 8,000. In some examples, the cross-sectional shape of the tow filament is "Y" shaped, but in other examples, other shapes such as "X" shaped or "O" shaped filaments may be used with the same dpf and total denier values ​​as described herein. The tow may contain filaments with a cross-sectional isoperimeter ratio of 25 or less, 20 or less, or 15 or less.

[0070] In some examples, the inner body 11 may include a capsule disposed within the material body. The capsule may include a burstable capsule (e.g., a capsule having a solid, fragile shell surrounding a liquid payload). In some examples, a single capsule is used. The capsule is entirely embedded within the material body. In other words, the capsule is completely enclosed by the material constituting the body. In other examples, multiple burstable capsules (e.g., two or more burstable capsules) may be disposed within the material body. The length of the material body is extendable to accommodate the required number of capsules. In examples where multiple capsules are used, the individual capsules may be identical to each other or may differ from each other in size and / or capsule payload. In other examples, multiple material bodies may be provided, each containing one or more capsules.

[0071] In some embodiments, the material body includes first and second capsules. In such embodiments, the first capsule is disposed in a first section of the material body, and the second capsule is disposed in a second section of the material body downstream of the first section. In other embodiments, the article comprises two material bodies, with the first and second capsules disposed in the first and second bodies, respectively.

[0072] The first capsule is heated to a first temperature before use, and the second capsule is heated to a second temperature before use, but the second temperature is at least 4°C lower than the first temperature. Preferably, the second temperature is at least 5, 6, 7, 8, 9, or 10°C lower than the first temperature.

[0073] In some embodiments, the second capsule is separated from the first capsule by a distance of at least 7 mm, measured as the distance between the centers of the first and second capsules. Preferably, the second capsule is separated from the first capsule by a distance of at least 8, 9, or 10 mm. Increasing the distance between the first and second capsules increases the temperature difference between the first and second capsules.

[0074] The first capsule contains an aerosol modifier. The second capsule also contains an aerosol modifier, which may be the same as or different from the aerosol modifier in the first capsule. In some embodiments, the user may release the aerosol modifier from each capsule by applying an external force to selectively rupture the first and second capsules.

[0075] The aerosol modifier in the second capsule is heated to a lower temperature than the aerosol modifier in the first capsule due to the temperature difference between the first and second capsules. The aerosol modifiers in the first and second capsules can be selected based on this temperature difference. For example, the first capsule may contain a first aerosol modifier with a lower vapor pressure than the second aerosol modifier in the second capsule. If both capsules are heated to the same temperature, a higher vapor pressure in the aerosol modifier of the second capsule means that more of the second aerosol modifier will volatilize compared to the aerosol modifier of the first capsule. However, because the second capsule is heated to a lower temperature, this effect is less pronounced, and the aerosol modifiers in the first and second capsules will volatilize more uniformly upon rupture of each capsule.

[0076] In some embodiments, the first and second capsules have the same aerosol modification profile, meaning that both capsules contain the same amount of the same type of aerosol modifying agent so that they modify the aerosol in the same way when both capsules are heated to the same temperature and rupture. However, since the first capsule is heated to a higher temperature than the second capsule, for example, more of the aerosol modifying agent in the first capsule volatilizes than the modifying agent in the second capsule, resulting in a more significant modification of the aerosol than the second capsule.

[0077] Therefore, even though both capsules are identical (which may make the manufacture of the aerosol modification component easier and / or cheaper), the user can decide whether to rupture the first capsule to modify the aerosol more, rupture the second capsule to modify the aerosol less, or rupture both capsules to modify the aerosol to the maximum extent.

[0078] In some embodiments, both the first and second capsules contain the first and second aerosol modifiers. The first aerosol modifier has a lower vapor pressure than the second aerosol modifier. Therefore, when the system is used to generate an aerosol, if the second capsule ruptures, a higher proportion of the second aerosol modifier will vaporize compared to the first aerosol modifier, compared to the case where the higher-temperature first capsule ruptures. This allows for different aerosol modifications to occur with the same capsules, depending on the position of the capsule in the first or second part of the aerosol modification component.

[0079] One or more capsules may have a core-shell structure. In other words, a capsule comprises a shell containing a liquid (e.g., a flavoring agent or other chemical substance (which may be either a flavoring agent or an aerosol modifier as described herein)). The shell is capable of releasing the flavoring agent or other chemical substance into the material body upon rupture by the user. The first plug wrap 16 may comprise a barrier coating that makes the material of the plug wrap substantially impermeable to the liquid payload of the capsule. Alternatively or in addition, the second plug wrap 17 and / or tip paper 18 may comprise a barrier coating that makes the material of the plug wrap and / or tip paper substantially impermeable to the liquid payload of the capsule.

[0080] In some cases, one or more capsules are spherical and have a diameter of approximately 3.5 mm. In other cases, capsules of other shapes and sizes (e.g., capsules with a diameter of 2.5 mm, 3 mm, 4 mm, or 4.5 mm) may also be used. The total weight of one or more capsules may range from approximately 10 mg to approximately 50 mg.

[0081] It is known that, for a given tow specification (8.4Y21000), a tow capability curve is generated that represents the pressure drop along the length of the rod formed using the tow for each of various tow weights. Parameters such as rod length, circumference, wrapper thickness, and tow plasticizer level are specified and combined with the tow specification to generate the tow capability curve. This curve provides an index of the pressure drop resulting from different tow weights between the minimum and maximum weights achievable by a standard filter rod forming machine. Such tow capability curves can be calculated, for example, using software available from tow suppliers. It has been found to be particularly advantageous to use an inner body 11 containing a filament tow with a weight per mm of length of approximately 10% to 30% of the range between the minimum and maximum weights of the tow capability curve generated for the filament tow. This can provide an acceptable balance between providing sufficient tow weight to avoid shrinkage after the inner body 11 is formed, while providing an acceptable pressure drop and assisting in the placement of the capsule within the tow, for capsules of the sizes described herein.

[0082] In some examples, the density of the material constituting the hollow tubular outer body 12 is at least about 0.25 grams / cm³ (g / cc), and in some examples at least about 0.3 g / cc. In some examples, the density of the hollow tubular outer body 12 is less than about 0.75 grams / cm³ (g / cc), and in some examples less than 0.6 g / cc. In some examples, the density of the hollow tubular outer body 12 is 0.25 g / cc to 0.75 g / cc, in some examples 0.3 to 0.6 g / cc, in some examples 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 improved hardness of high-density materials and the low heat transfer properties of low-density materials. In examples where the outer body is formed by filament tow, the "density" of the hollow tubular outer body 12 represents the density of the filament tow constituting the body into which any plasticizer is incorporated. The density can be determined by dividing the total weight of the hollow tubular outer body 12 by the total volume of the hollow tubular outer body 12, and the total volume can be calculated using appropriate measurement results of the hollow tubular outer body 12 obtained, for example, using a caliper. If necessary, appropriate dimensions may be measured by a microscope.

[0083] In some examples, the filament tow constituting the hollow tubular outer body 12 has a total denier of less than 45,000, and in some examples, less than 42,000. It has been found that this total denier is sufficient to form a tubular outer body 12 with a relatively low density. In some examples, the total denier is at least 20,000, and in some examples, at least 25,000. In some examples, the filament tow constituting the hollow tubular outer body 12 has a total denier of 25,000 to 45,000, and in some examples, 35,000 to 45,000. In some examples, the cross-sectional shape of the tow filament is "Y" shaped, but in other examples, other shapes such as "X" shaped or "O" shaped filaments can also be used. This tow may contain filaments with a cross-sectional isoperimetric ratio of 25 or less, 20 or less, or 15 or less.

[0084] In some examples, the filament tow constituting the outer body 12 has a denier per filament greater than 3. It has been found that this denier per filament allows for the formation of an outer body 12 with a relatively low density. In some examples, the denier per filament is at least 4, and in some examples, at least 5. In some examples, the filament tow constituting the outer body 12 has a denier per filament of 4 to 10, and in some examples, 4 to 9. In one example, the filament tow constituting the outer body 12 is formed of cellulose acetate and has an 8Y40,000 tow containing 18% plasticizer (e.g., triacetin).

[0085] In some examples, the hollow tubular outer body 12 contains 15% to 22% by weight of plasticizer. In the case of cellulose acetate tow, the plasticizer is preferably triacetin, but other plasticizers such as polyethylene glycol (PEG) can also be used. In some examples, the outer body 12 contains 16% to 20% by weight of plasticizer (e.g., about 17%, about 18%, or about 19%).

[0086] In some examples, the inner body 11 and / or outer body 12 can be formed from paper, similar to paper filters known for use in cigarettes, for example. In such examples, the density of the paper constituting the inner body is lower than that of the paper constituting the outer body, so that the resistance to gas flow in the longitudinal direction of the inner body is less than that of the outer body.

[0087] In some cases, the length of the inner body 11 is less than approximately 15 mm. In some cases, the length of the inner body is less than approximately 12 mm. As an addition or alternative, the length of the inner body 11 is at least approximately 5 mm. In some cases, the length of the inner body 11 is at least approximately 6 mm. In some cases, the length of the inner body 12 is approximately 5 mm to approximately 20 mm, in some cases approximately 6 mm to approximately 10 mm, in some cases approximately 6 mm to approximately 8 mm, in some cases approximately 6 mm, 7 mm, or approximately 8 mm.

[0088] In some cases, the length of the hollow tubular outer body 12 is less than approximately 15 mm. In some cases, the length of the hollow tubular outer body 12 is less than approximately 12 mm. As an addition or alternative, the length of the hollow tubular outer body 12 is at least approximately 5 mm. In some cases, the length of the hollow tubular outer body 12 is at least approximately 6 mm. In some cases, the length of the hollow tubular outer body 12 is approximately 5 mm to approximately 20 mm, in some cases approximately 6 mm to approximately 10 mm, in some cases approximately 6 mm to approximately 8 mm, and in some cases approximately 6 mm, 7 mm, or approximately 8 mm.

[0089] In some examples, the length of the inner body is the same as the length of the outer body. In this example, both the inner and outer bodies are 10 mm in length.

[0090] In this example, the tubular outer body 12 has an outer circumference of approximately 21 mm, corresponding to an outer diameter of approximately 6.7 mm. In some examples, the hollow tubular outer body 12 has an inner diameter greater than 3.0 mm. If the diameter is smaller, the velocity of the aerosol passing through the component 10 and reaching the user's mouth increases unnecessarily, potentially causing the aerosol to overheat and reach temperatures of, for example, over 40°C or 45°C. In some examples, the hollow tubular outer body 12 has an inner diameter greater than 3.1 mm, and in some examples greater than 3.5 mm or 3.6 mm. In this example, the inner diameter of the hollow tubular outer body 12 is approximately 3.9 mm.

[0091] The "wall thickness" of the hollow tubular outer body 12 corresponds to the thickness of the wall of the outer body 12 in the radial direction. This may be measured, for example, using a caliper. The wall thickness is preferably greater than 0.9 mm, and in some cases greater than 1.0 mm. In some cases, the wall thickness is substantially constant around the entire wall of the hollow tubular outer body 12. However, in cases where the wall thickness is not substantially constant, it is greater than 0.9 mm at any point around the hollow tubular outer body 12, and in some cases greater than 1.0 mm.

[0092] In this example, component 10 further comprises a hollow tubular element 14, the tubular element 14 including a hollow cavity 14a extending through the hollow tubular element 14.

[0093] The outer body 12 and the hollow tubular element 14 each define a substantially cylindrical overall shape and share a common longitudinal axis. In this example, the hollow tubular element 14 is adjacent to and in contact with the outer body 12. In some examples, the hollow tubular element 14 may be adjacent to and in contact with both the inner body 11 and the outer body 12.

[0094] In this example, the tubular element 14 is positioned downstream of the inner body 11 and the outer body 12 when the component 10 is incorporated into an article used with the non-combustible aerosol supply device. Thus, the tubular element 14 constitutes the mouth end of the component 10. Alternatively or additionally, the tubular element may be positioned upstream of the inner body and the outer body when the component 10 is incorporated into an article used with the non-combustible aerosol supply device.

[0095] The tubular element 14 may be substantially the same as the hollow tubular outer body 12, or it may have any of the dimensions mentioned above in relation to the hollow tubular outer body 12.

[0096] In this example, the tubular element 14 has a length of 6 mm. In some examples, it may be particularly advantageous to use a hollow tubular element 14 with a length of approximately 10 mm or more (e.g., approximately 10 mm to approximately 30 mm or approximately 12 mm to approximately 25 mm). Since the consumer's lips may extend approximately 12 mm from the mouth end of the article 1 when drawing in an aerosol through the article 1, it has been found that a length of at least 10 mm or at least 12 mm for the hollow tubular element 14 means that a large portion of the consumer's lips will surround this element 14.

[0097] In this example, component 10 comprises an outer body 12 and a plug wrap 18 wrapped around a tubular body 14. In some examples, the plug wrap 18 has a basic weight of less than 50 gsm, and in some examples, about 20 gsm to 40 gsm. In some examples, the plug wrap 18 has a thickness of 30 μm to 60 μm, and in some examples, 35 μm to 45 μm. In some examples, the plug wrap 18 is a non-porous plug wrap (e.g., having an air permeability of less than 100 cholesta units (e.g., less than 50 cholesta units)). However, in other examples, the plug wrap 18 can be a porous plug wrap (e.g., it may have an air permeability of more than 200 cholesta units).

[0098] In some examples, component 10 comprises another plug wrap (not shown) wrapped around the inner body 11. In some examples, this additional plug wrap has a basic weight of less than 50 gsm, and in some examples, about 20 gsm to 40 gsm. In some examples, this additional plug wrap has a thickness of 30 μm to 60 μm, and in some examples, 35 μm to 45 μm. In some examples, this additional plug wrap is a non-porous plug wrap (e.g., having an air permeability of less than 100 cholesta units (e.g., less than 50 cholesta units)). However, in other examples, this additional plug wrap can be a porous plug wrap (e.g., having an air permeability of more than 200 cholesta units).

[0099] Figure 2 is a lateral cross-sectional view of an article used with a non-combustible aerosol supply device. In this example, article 1 comprises the component 10 shown in Figures 1a and 1b. Component 10 acts as the mouthpiece of article 1 and defines the mouth end of article 1.

[0100] Article 1 comprises a cylindrical rod of aerosol-generating material 21 (in this case, tobacco material), a hollow tubular element 23 disposed downstream of the aerosol-generating material 21, and a mouthpiece 10 disposed downstream of the tubular element 23. The mouthpiece 10, comprising an inner body 11 and an outer body 12, can improve the isolation between the aerosol and the user's lips compared to a standard cellulose acetate plug without extending the overall length of Article 1.

[0101] In this example, the aerosol-generating material 21 is covered with a wrapper 22. The wrapper 22 can be, for example, a paper foil wrapper or a foil wrapper with paper backing.

[0102] The wrapper 22 may have a high level of permeability (more than approximately 1000 cholesta units in some cases, more than approximately 1500 cholesta units in some cases, or more than approximately 2000 cholesta units in some cases). The wrapper 22 may have a maximum permeability of less than approximately 20000 cholesta units, less than approximately 15000 cholesta units in some cases, or less than approximately 5000 cholesta units in some cases. The permeability of the wrapper 22 can be measured according to ISO 2965:2009 for determining the permeability of materials used as cigarette paper, filter plug wraps, and filter bonding paper.

[0103] The wrapper 22 may be made of a material with a high intrinsic air permeability level, an intrinsically porous material, or a material with any intrinsic air permeability level, such that the final air permeability level is achieved by providing the wrapper 22 with ventilation zones or areas. If the wrapper 22 has ventilation zones, these ventilation zones may be discrete areas or may extend substantially throughout the entire wrapper 22. For example, the wrapper 22 may have discrete, strip-shaped ventilation perforations, or it may have ventilation perforations that extend substantially around the entire wrapper 22. The wrapper 22 may have ventilation perforations of any configuration to achieve the final air permeability level. The percentage of the surface area of ​​a wrapper having the air permeability level described herein may be greater than 50%, greater than 75%, greater than 90%, or 100%.

[0104] In this example, ventilation is provided directly to the tubular element 23 through the ventilation area 24. In this example, the ventilation area 24 includes first and second parallel rows of perforations, which in this case are laser perforations, formed at positions 17.925 mm and 18.625 mm from the downstream end of the mouthpiece 10, respectively. These perforations pass through the tip paper 28 and the hollow tubular element 23. Alternatively, the ventilation can be provided to the tubular element through a single row of perforations (e.g., laser perforations). This has been shown to improve aerosol formation, which is thought to be a result of the airflow through the perforations being more uniform for a given ventilation level than in the case of multiple rows of perforations.

[0105] When in use, the user draws air through article 1, and the air enters article 1 through the perforations 24. The ventilation area 24 gives the article a ventilation level of less than 50% of the air drawn in through the article. In some examples, the article may have a ventilation level in which 50% to 80% (e.g., 45% to 65%) of the aerosol is drawn in through the article. These levels of ventilation help to slow down the flow of aerosol drawn in through article 1, so that the aerosol can be sufficiently cooled before reaching the downstream end of article 1.

[0106] It is known that aerosol temperature generally increases with decreasing ventilation levels. However, the relationship between aerosol temperature and ventilation level does not appear to be linear; for example, variations in ventilation due to manufacturing tolerances have less impact as the target ventilation level decreases. For instance, if the allowable ventilation range is ±15% and the target ventilation level is 75%, the aerosol temperature may rise by approximately 6°C at the lower limit of ventilation (60% ventilation). However, if the target ventilation level is 60%, the aerosol temperature may rise by only about 3.5°C at the lower limit of ventilation (45% ventilation). Therefore, a target ventilation level for an article can be in the range of 40% to 70% (e.g., 45% to 65%). The average ventilation level for at least 20 articles can be 40% to 70% (e.g., 45% to 70% or 51% to 59%).

[0107] By providing a breathable wrapper 22, a route is given for air to enter the article 1. In some examples, the wrapper 22 can be made breathable such that the amount of air entering the article through the rod of aerosol-generating material is relatively greater than the amount of air entering the article through the breathable area 24 of the tubular element 23. Articles with this configuration are capable of generating a more flavorful aerosol that may be more satisfying to the user.

[0108] Item 1 has an internal volume of 450 mm 3 It includes a cavity of at least this volume. It has been shown that providing a cavity of at least this volume enables improved aerosol formation. Such a cavity size provides sufficient space within article 1 to cool the heated volatile components, thus allowing the aerosol-generating material 21 to be exposed to temperatures higher than those achievable by other methods, which could otherwise cause the aerosol temperature to rise too high.

[0109] In this example, the cavity is a cavity 23a formed within a hollow tubular element 23, but in alternative configurations, it can be formed in a different part of article 1. In some examples, article 1 has an internal volume of 500 mm 3In some cases, it's as long as 550mm. 3 Further aerosol improvement is possible by including an extra cavity (for example, a cavity 23a formed within a hollow tubular element 23). In some examples, the internal cavity is approximately 550 mm 3 ~about 750mm 3 (For example, approximately 600 mm) 3 Or 700mm 3 It has a volume of ).

[0110] In this example, the hollow tubular element 23 is adjacent to the inner body 11 and the outer body 12 immediately upstream of them. The hollow tubular element 23, the outer body 12, and the tubular body 14 each define a substantially cylindrical overall shape and share a common longitudinal axis.

[0111] In this example, the hollow tubular element 23 is formed from multiple layers of paper wound parallel to each other with seams facing each other to constitute the tubular element 23. In this example, the first and second paper layers are provided as a double tube, but in other examples, three or four or more layers of paper can be used to form triple or quadruple or more tubes. Other configurations can also be used, such as spirally wound paper layers, cardboard tubes, tubes formed by a papier-mâché process, molded or extruded plastic tubes, or similar materials.

[0112] Furthermore, the hollow tubular element 23 can be formed, for example, by using rigid plug wrap and / or tip paper as plug wrap 18 and / or tip paper 28, which means that a separate tubular element is not required. This rigid plug wrap and / or tip paper is manufactured to have sufficient rigidity to withstand the axial compressive forces and bending moments that may occur during manufacturing and use of article 1. For example, this rigid plug wrap and / or tip paper may have a basic weight of 70 gsm to 120 gsm, and in some examples 80 gsm to 110 gsm. As an addition or alternative, the above rigid plug wrap and / or tip paper may have a thickness of 80 μm to 200 μm, in some examples 100 μm to 160 μm, or 120 μm to 150 μm.

[0113] The tubular element 23 preferably has a wall thickness of at least about 325 μm to about 2 mm, preferably 500 μm to 1.5 mm, and more preferably 750 μm to 1 mm. In this example, the tubular element 23 has a wall thickness of about 1 mm. The "wall thickness" of the tubular element 23 corresponds to the wall thickness of the tubular element 23 in the radial direction. This may be measured, for example, using a caliper.

[0114] In some embodiments, the wall thickness of the tubular element is at least 325 microns, preferably at least 400, 500, 600, 700, 800, 900, or 1000 microns. In some embodiments, the wall thickness of the tubular element is at least 1250 or 1500 microns.

[0115] In some embodiments, the wall thickness of the tubular element is less than 2000 microns, preferably less than 1500 microns.

[0116] Increasing the wall thickness of a tubular element means increasing its thermal mass, which has been shown to help lower the temperature of aerosols passing through the element and also lower the surface temperature of the article downstream of the element. This is thought to be because a larger thermal mass in a tubular element allows it to absorb more heat from aerosols compared to a tubular element with thinner walls. Furthermore, as the thickness of the tubular element increases, aerosols pass through the center of the article, so less heat from the aerosols is transferred to the outer parts of the article, such as the outer parts of the material itself.

[0117] In some embodiments, the air permeability of the wall material of the tubular element is at least 100 cholestas, preferably at least 500 or 1000 cholestas.

[0118] It has been found that when the air permeability of a tubular element is relatively high, the amount of heat transferred from the aerosol to the tubular element increases, thus lowering the temperature of the aerosol. It has also been found that the air permeability of a tubular element increases the amount of moisture transferred from the aerosol to the tubular element, which improves the user's perception of the aerosol in their mouth. Furthermore, high air permeability of a tubular element makes it easier to create ventilation holes using a laser, which means that low-power lasers can be used.

[0119] In some examples, the length of the hollow tubular element 23 is less than approximately 50 mm. In some examples, the length of the hollow tubular element 23 is less than approximately 40 mm. In some examples, the length of the hollow tubular element 23 is less than approximately 30 mm. As an addition or alternative, the length of the hollow tubular element 23 is at least approximately 10 mm. In some examples, the length of the hollow tubular element 23 is at least approximately 15 mm. In some examples, the length of the hollow tubular element 23 is approximately 20 mm to approximately 30 mm, in some examples approximately 22 mm to approximately 28 mm, and in some examples approximately 24 mm to approximately 26 mm. In this example, the length of the hollow tubular element 23 is 25 mm.

[0120] The hollow tubular element 23 is positioned around and defines a void within the article 1 that acts as a cooling segment. The void provides a chamber through which heated volatile components generated by the aerosol-generating material 21 flow. The hollow tubular element 23 is hollow and provides an aerosol-accumulating chamber that is rigid enough to withstand axial compressive forces and bending moments that may occur during manufacturing and use of the article 1. The hollow tubular element 23 provides a physical displacement between the aerosol-generating material 21 and the inner and outer bodies 11, 12. The physical displacement provided by the hollow tubular element 23 results in a thermal gradient along the entire length of the hollow tubular element 23.

[0121] The hollow tubular element 23 can be configured to create a temperature difference of at least 40°C between the heated volatile components entering the first upstream end of the hollow tubular element 23 and the heated volatile components exiting the second downstream end of the hollow tubular element 23. Preferably, the hollow tubular element 23 is configured to create a temperature difference of at least 60, 80, or preferably 100°C between the heated volatile components entering the first upstream end of the hollow tubular element 23 and the heated volatile components exiting the second downstream end of the hollow tubular element 23. This temperature difference along the entire length of the hollow tubular element 23 protects the temperature-sensitive material bodies 11 and 12 from the high temperature of the aerosol-generating material 21 when heated.

[0122] In some examples, the aerosol-generating material described herein is the first aerosol-generating material, and the hollow tubular element 23 may contain the second aerosol-generating material. The walls of the hollow tubular element 23 may contain the second aerosol-generating material. For example, the second aerosol-generating material can be disposed on the inner surface of the walls of the hollow tubular element 23.

[0123] The second aerosol-generating material comprises at least one aerosol-forming material and may also comprise at least one aerosol-modifying agent or other sensory material. The aerosol-forming material and / or aerosol-modifying agent may be any aerosol-forming material or aerosol-modifying agent as described herein, or any combination thereof.

[0124] When the aerosol generated from the aerosol generating material 21 (in this case, referred to as the first aerosol) is drawn in through the hollow tubular element 23 of the mouthpiece 10, the heat from the first aerosol can aerosolize the aerosol-forming material of the second aerosol generating material, thereby forming the second aerosol. The second aerosol may contain a flavoring agent, which may be an addition to or complement to the flavoring agent of the first aerosol.

[0125] By providing a second aerosol-generating material in the hollow tubular element 23, a second aerosol can be generated that enhances or complements the flavor or visual appearance of the first aerosol.

[0126] In alternative articles, the hollow tubular element 23 can be replaced with an alternative cooling element (for example, an element formed of a material body that allows longitudinal passage of aerosols and performs the function of cooling the aerosols).

[0127] The aerosol-generating material 21 (also referred to herein as aerosol-generating substance 21) comprises at least one aerosol-forming material. In this example, the aerosol-forming material is glycerol. In alternative examples, other materials as described herein, or combinations thereof, may be used as the aerosol-forming material. Aerosol-forming materials are known to improve the sensory performance of an article by facilitating the transfer of compounds such as flavor compounds from the aerosol-generating material to the consumer. However, a problem with adding such an aerosol-forming material to the aerosol-generating material in an article for use in a non-combustible aerosol supply system is that, when the aerosol-generating material is aerosolized by heating, the mass of the aerosol delivered by the article increases, and this increased mass may maintain a high temperature as it passes through the mouthpiece. As the aerosol passes through the mouthpiece, it transfers heat to the mouthpiece, causing the outer surface of the mouthpiece, including the area that comes into contact with the consumer's lips during use, to become hot. The temperature of the mouthpiece can be significantly higher than, for example, the temperature a consumer might be accustomed to when smoking a conventional cigarette, which can be an undesirable effect resulting from the use of aerosol-forming materials as described above.

[0128] In this example, Article 1 has a circumference of approximately 21 mm (i.e., the article is of the demi-slim type). In other examples, the article can be provided in any of the types described herein (e.g., circumference of 15 mm to 25 mm). To heat the article and release aerosols, improved heating efficiency can be achieved by using articles with a smaller circumference within this range (e.g., circumference less than 23 mm). It has also been found that articles with a circumference greater than 19 mm are particularly effective in achieving improved aerosol delivery by heating while maintaining a suitable product length. Articles with a circumference of 19 mm to 23 mm, more preferably 20 mm to 22 mm, have been found to provide a good balance for achieving effective aerosol delivery while enabling efficient heating.

[0129] The chip paper 28 is wrapped around the outer body 12, the tubular body 14, and the tubular element 23, and covers at least a portion of the rod of the aerosol generating material 21. The chip paper 28 has an adhesive on its inner surface that connects the outer body 12, the tubular body 14, the tubular element 23, and the rod of the aerosol generating material 21. In this example, the chip paper 28 extends 5 mm over the rod of the aerosol generating material 21, but as an alternative, the outer body 12, the tubular body 14, the tubular element 23, and the rod of the aerosol generating material 21 can be securely connected by extending 3 mm to 10 mm, or in some examples 4 mm to 6 mm, over the rod 21.

[0130] The chip paper 28 (also referred to herein as the wrapper) may have a base weight greater than the base weight of the plug wrap used in article 1 (for example, 40 gsm to 80 gsm, 50 gsm to 70 gsm in some examples, and 58 gsm in this example). Within this range of base weights, the chip paper has been found to have an acceptable tensile strength while being flexible enough to wrap around article 1 and adhere to itself along the longitudinal seams of the paper. When wrapped around the aerosol-generating material 20, the outer circumference of the chip paper 28 is approximately 21 mm.

[0131] In some cases, the chip paper contains citric acid such as sodium citrate and / or potassium citrate. In some cases, the citric acid content of the chip paper may be 2% by weight or less, or 1% by weight or less. A lower citric acid content in the wrapper may help to suppress any visual discoloration of the wrapper during use.

[0132] In this example, the aerosol-forming material added to the aerosol-generating substrate 21 constitutes 14% by weight of the aerosol-generating substrate 21. In some examples, the aerosol-forming material constitutes at least 5% by weight of the aerosol-generating substrate, and in some examples at least 10%. In some examples, the aerosol-forming material constitutes less than 25% by weight of the aerosol-generating substrate, and in some examples less than 20% (e.g., between 10% and 20%, between 12% and 18%, or between 13% and 16%).

[0133] In some examples, the article 1 may be configured such that the heater of the non-combustible aerosol supply device 100 and the hollow tubular element 23 are separated (i.e., at the shortest distance). Thereby, damage to the material constituting the hollow tubular element due to heat from the heater is prevented.

[0134] The shortest distance between the heater of the non-combustible aerosol supply device 100 and the hollow tubular element 23 may be 3 mm or more. In some examples, the shortest distance between the heater of the non-combustible aerosol supply device 100 and the hollow tubular element 23 may be in the range of 3 mm to 10 mm (e.g., 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm).

[0135] The separation between the heating element of the non-combustible aerosol supply device 100 and the hollow tubular element 23 may be configured to be achieved, for example, by adjusting the length of the aerosol-generating material 21.

[0136] In some examples, the aerosol-generating material 21 is provided as a cylindrical rod of the aerosol-generating material. Regardless of the form of the aerosol-generating material, its length is preferably about 10 mm to 100 mm. In some examples, the length of the aerosol-generating material is in the range of about 25 mm to 50 mm, in some examples in the range of about 30 mm to 45 mm, and in some examples about 30 mm to 40 mm.

[0137] The volume of a given aerosol-generating material 21 is about 200 mm<~Approximately 4300mm 3 Preferably about 500 mm 3 ~1500mm 3 , more comfortably approximately 1000mm 3 ~approximately 1300mm 3 The volume of these aerosol-generating materials (e.g., about 1000 mm³) can vary between these two ranges. 3 ~approximately 1300mm 3 Providing ) has been shown to be advantageous in achieving superior aerosols with greater visibility and sensory performance compared to those achieved at volumes selected from the lower end of this range.

[0138] The mass of the given aerosol-generating material 21 can be greater than 200 mg (for example, about 200 mg to about 400 mg, preferably about 230 mg to 360 mg, more preferably about 250 mg to about 360 mg). It has been found that increasing the mass of the aerosol-generating material is advantageous because it improves sensory performance compared to aerosols generated from low-mass tobacco material.

[0139] The aerosol-generating material or substrate is preferably formed from a tobacco material as described herein, which contains tobacco components.

[0140] In the tobacco materials described herein, the tobacco component preferably includes recycled tobacco. The tobacco component may also include loose tobacco, extruded tobacco, and / or shredded tobacco.

[0141] The aerosol-generating material 21 may include recycled tobacco material with a density of less than approximately 700 milligrams / cubic centimeter (mg / cc). Such tobacco material has been found to be particularly effective in providing an aerosol-generating material that can release aerosols by rapid heating, compared to high-density materials. For example, the inventors tested the properties of various aerosol-generating materials, such as shredded recycled tobacco material and paper recycled tobacco material, when heated. For each given aerosol-generating material, it was found that a specific zero heat flow temperature exists while heat is applied to the material. Below this temperature, the net heat flow is endothermic, meaning that more heat enters the material than leaves it. Above this temperature, the net heat flow is exothermic, meaning that more heat leaves the material than enters it. Materials with a density of less than 700 mg / cc had a low zero heat flow temperature. Since most of the heat released from the material is due to aerosol formation, lowering the zero heat flow temperature has a beneficial effect on the time it takes for the aerosol-generating material to first release aerosols. For example, it was found that aerosol-generating materials with a density of less than 700 mg / cc have a zero heat flow temperature of less than 164°C compared to materials with a density exceeding 700 mg / cc and a zero heat flow temperature of more than 164°C.

[0142] Furthermore, the density of the aerosol-generating material also affects the rate at which heat is conducted through the material. The lower the density (for example, below 700 mg / cc), the slower the heat is conducted through the material, allowing for more sustained aerosol release.

[0143] The aerosol-generating material 21 preferably contains recycled tobacco material (e.g., recycled paper tobacco material) with a density of less than approximately 700 mg / cc. The aerosol-generating material 20 more preferably contains recycled tobacco material with a density of less than approximately 600 mg / cc. Alternatively or in addition, the aerosol-generating material 21 preferably contains recycled tobacco material with a density of at least 350 mg / cc, which is thought to enable a sufficient amount of heat conduction to the material.

[0144] The tobacco material may be provided in the form of shredded rag tobacco. The shredded rag tobacco may have a cut width of at least 15 cuts per inch (approximately 5.9 cuts per cm, corresponding to a cut width of approximately 1.7 mm). Preferably, the shredded rag tobacco has a cut width of at least 18 cuts per inch (approximately 7.1 cuts per cm, corresponding to a cut width of approximately 1.4 mm), and more preferably, at least 20 cuts per inch (approximately 7.9 cuts per cm, corresponding to a cut width of approximately 1.27 mm). In one example, the shredded rag tobacco has a cut width of 22 cuts per inch (approximately 8.7 cuts per cm, corresponding to a cut width of approximately 1.15 mm). Preferably, the shredded rag tobacco has a cut width of 40 cuts or less per inch (approximately 15.7 cuts per cm, corresponding to a cut width of approximately 0.64 mm). It has been found that a cutting width of 0.5 mm to 2.0 mm (for example, 0.6 mm to 1.5 mm or 0.6 mm to 1.7 mm) is a preferred tobacco material, particularly in terms of the surface area to volume ratio during heating and the overall density and pressure reduction of the base material 20. Shredded rag tobacco can be formed from a mixture of multiple forms of tobacco material (for example, a mixture of one or more of recycled tobacco, loose leaf tobacco, extruded tobacco, and shredded tobacco). The tobacco material preferably includes recycled tobacco or a mixture of recycled tobacco and loose leaf tobacco.

[0145] In the tobacco materials described herein, the tobacco material may contain filler components. Generally, the filler components are non-tobacco components, i.e., components that do not contain tobacco-derived substances. The filler components may be non-tobacco fibers such as wood fibers, i.e., pulp or wheat fibers. Alternatively, the filler components may be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Furthermore, the filler components may be non-tobacco cast materials or non-tobacco extruded materials. The filler components may be present in an amount of 0 to 20% by weight of the tobacco material or in an amount of 1 to 10% by weight of the composition. In some embodiments, no filler components are present.

[0146] In the tobacco materials described herein, the tobacco materials include an aerosol-forming material. In this context, “aerosol-forming material” is a chemical substance that promotes aerosol formation. The aerosol-forming material may promote aerosol formation by promoting the initial vaporization of the gas and / or condensation into an aspirable solid and / or liquid aerosol. In some embodiments, the aerosol-forming material may improve the supply of flavoring from the aerosol-forming material. Generally, the aerosol-forming material of the present invention includes those described herein and may include any suitable aerosol-forming material or shaping agent. Other suitable aerosol-forming materials include, but are not limited to, sorbitol, glycerol, polyols such as glycols like propylene glycol or triethylene glycol, monohydric alcohols, high-boiling hydrocarbons, acids such as lactic acid, glycerol derivatives, esters such as diacetin, triacetin, triethylene glycol diacetate, triethyl citrate, or myristicates including ethyl myristate and isopropyl myristate, and non-polyols such as aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate, and dimethyl tetradecanedioate. In some embodiments, the aerosol-forming material may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. Glycerol may be present in an amount of 10-20% by weight of the tobacco material (e.g., 13-16% of the composition) or about 14% or 15% by weight of the composition. If propylene glycol is present, it may be present in an amount of 0.1-0.3% by weight of the composition.

[0147] The aerosol-forming material may be included in any component of the tobacco material (e.g., any tobacco component) and / or filler component (if present). Alternatively or in addition, the aerosol-forming material may be added separately to the tobacco material. In any case, the total amount of the aerosol-forming material in the tobacco material may be as specified herein.

[0148] The tobacco material can contain 10% to 90% by weight of tobacco leaves, and the aerosol-forming material is supplied in an amount of up to approximately 10% by weight of tobacco leaves. To achieve an overall level of aerosol-forming material of 10% to 20% by weight of the tobacco material, it is advantageous to be able to add this to other components of the tobacco material (such as recycled tobacco material) at a higher weight percentage.

[0149] The tobacco materials described herein contain nicotine. The nicotine content is 0.5 to 1.75% by weight of the tobacco material, and may be, for example, 0.8 to 1.5% by weight of the tobacco material. As an addition or alternative, the tobacco material includes tobacco leaves with a nicotine content of more than 1.5% by weight, ranging from 10% to 90% by weight. It has been found that using tobacco leaves with a nicotine content higher than 1.5% in combination with a low-nicotine-based material (such as recycled cigarettes) results in an appropriate nicotine level for the tobacco material, while also providing improved sensory performance compared to using recycled cigarettes alone. The nicotine content of tobacco leaves (e.g., shredded rag tobacco) can be, for example, 1.5% to 5% by weight of the tobacco leaves.

[0150] The tobacco materials described herein may include aerosol modifiers, such as any of the flavorings described herein. In one embodiment, the tobacco material constitutes a menthol article by including menthol. The tobacco material may contain 3 mg to 20 mg of menthol, preferably 5 mg to 18 mg, more preferably 8 mg to 16 mg of menthol. In this example, the tobacco material contains 16 mg of menthol. The tobacco material may contain 2% 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 tobacco material contains 4.7% by weight of menthol. Such high levels of menthol filling can be achieved by using a high proportion (e.g., more than 50% by weight of the tobacco material) of recycled tobacco material. Alternatively or in addition, using a large amount of aerosol-generating material (e.g., tobacco material) can result in, for example, about 500 mm3 For over or preferably approximately 1000 mm 3 When ultra-high aerosol-generating materials (such as tobacco materials) are used, the level of menthol filling that can be achieved can be increased.

[0151] In the compositions described herein, where amounts are given in weight percent, this represents a dry weight basis unless otherwise specified to avoid doubt. Therefore, any moisture that may be present in the tobacco material or its components is completely disregarded for the purpose of determining the weight percent. The moisture content of the tobacco material described herein may vary, for example, from 5 to 15% by weight. The moisture content of the tobacco material described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The moisture content can be determined by Karl Fischer analysis as understood by those skilled in the art. On the other hand, to avoid doubt, even if the aerosol-forming material is a liquid-phase component (such as glycerol or propylene glycol), any component other than moisture is included in the weight of the tobacco material. However, if the aerosol-forming material is given to the tobacco component of the tobacco material or the filler component of the tobacco material (if present) as an alternative to or addition to the tobacco material, the aerosol-forming material is not included in the weight of the tobacco component or the filler component, but is included in the weight of the "aerosol-forming material" in weight percent as specified herein. All other components present in the tobacco product, even if they are non-tobacco-derived (for example, non-tobacco fibers in recycled cigarettes), are included in the weight of the tobacco product.

[0152] In one embodiment, the tobacco material comprises tobacco components as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material essentially consists of tobacco components as defined herein and an aerosol-forming material as defined herein. In one embodiment, the tobacco material consists of tobacco components as defined herein and an aerosol-forming material as defined herein.

[0153] In the tobacco components of the tobacco materials described herein, recycled tobacco is present in an amount of 10% to 100% by weight of the tobacco components. In one embodiment, recycled tobacco is present in an amount of 10% to 80% or 20% to 70% by weight of the tobacco components. In another embodiment, the tobacco components consist essentially of recycled tobacco or consist of recycled tobacco. In a preferred embodiment, the tobacco components of the tobacco material contain at least 10% by weight of tobacco leaves. For example, at least 10% by weight of tobacco leaves may be present, while the remainder of the tobacco components may include recycled tobacco, shredded recycled tobacco, or a combination of shredded recycled tobacco and other forms of tobacco such as tobacco granules. Recycled tobacco refers to tobacco material formed by a process in which tobacco raw materials are extracted with a solvent to obtain a residue containing soluble extracts and fibrous material, and then the extract (usually concentrated, and optionally processed separately) is deposited onto the fibrous material (usually purified, and optionally simultaneously with the addition of some non-tobacco fibers) to recombine the extract with the fibrous material of the residue. The recombination process is similar to the process of making paper.

[0154] The recycled cigarette may be any type of recycled cigarette known in the art. In one particular embodiment, the recycled cigarette is made from raw materials comprising one or more of tobacco strips, tobacco stems, and whole leaf tobacco. In another embodiment, the recycled cigarette is made from raw materials consisting of tobacco strips and / or whole leaf tobacco and tobacco stems. However, as an alternative or addition, in other embodiments, scrap, fine, and winnowing may be used as raw materials.

[0155] The recycled cigarettes used in the tobacco materials described herein may be produced by methods known to those skilled in the art of producing recycled cigarettes.

[0156] A non-combustible aerosol supply device is used to heat the aerosol-generating material 21 of article 1. The non-combustible aerosol supply device is preferably equipped with a coil, as it has been shown to improve heat transfer to article 1 compared to other configurations.

[0157] In some examples, the coil is configured to heat at least one conductive heating element when in use, so that thermal energy is transferred from at least one conductive heating element to the aerosol-generating material, thereby heating the aerosol-generating material.

[0158] In some examples, a coil is configured to generate a fluctuating magnetic field that penetrates at least one heating element during use, thereby inductively heating and / or magnetically hysterically heating the at least one heating element. In such configurations, the heating element or each heating element may be referred to as a “susceptor” as defined herein. A coil configured to generate a fluctuating magnetic field that penetrates at least one conductive heating element during use, thereby inductively heating at least one conductive heating element, may be referred to as an “induction coil” or “inductor coil.”

[0159] The device may comprise one or more heating elements (e.g., one or more conductive heating elements), which may be configured to heat the heating elements as described above, depending on their suitable arrangement or configuration relative to the coil. The heating elements may be located in a fixed position relative to the coil. Alternatively, at least one heating element (e.g., at least one conductive heating element) may be included in an article 1 inserted into the heating zone of the device, the article 1 containing an aerosol-generating material 21, and removable from the heating zone after use. Alternatively, both the device and such article 1 may comprise at least one heating element each (e.g., at least one conductive heating element), and the coil may be configured to heat the heating elements of the device and the article respectively when the article is in the heating zone.

[0160] In some examples, the coil is helical. In some examples, the coil surrounds at least a portion of the heating zone of a device configured to receive an aerosol-generating material. In some examples, the coil is a helical coil surrounding at least a portion of the heating zone.

[0161] In some examples, the device comprises a conductive heating element that at least partially encloses the heating zone, and the coil is a helical coil that encloses at least a portion of the conductive heating element. In some examples, the conductive heating element is tubular. In some examples, the coil is an inductor coil.

[0162] In some cases, the use of a coil allows a non-combustible aerosol supply device to reach its operating temperature faster than a non-coiled aerosol supply device. For example, a non-combustible aerosol supply device equipped with the coil described above may reach its operating temperature in less than 30 seconds, more preferably less than 25 seconds, from the start of the device heating program, enabling it to provide its first puff. In some cases, the device may reach its operating temperature in about 20 seconds from the start of the device heating program.

[0163] It has been observed that heating aerosol-generating materials using a coil as described herein increases the amount of aerosol produced. For example, consumers have reported that aerosols produced by devices equipped with a coil as described herein are subjectively closer to those produced by factory-made tobacco (FMC) products than aerosols produced by other non-combustible aerosol supply systems. Without being bound by theory, this is assumed to be a result of the reduced time to reach the required heating temperature when using a coil, the higher achievable heating temperature when using a coil, and / or the fact that such a system can heat a relatively large amount of aerosol-generating material simultaneously with a coil, resulting in the aerosol temperature being similar to that of FMC aerosols. In FMC products, burning charcoal generates high-temperature aerosols, which are drawn through a rod, heating the tobacco in the tobacco rod behind the charcoal. This high-temperature aerosol is understood to cause the tobacco in the rod behind the burning charcoal to release flavor compounds. Furthermore, it is believed that a device equipped with a coil as described herein heats an aerosol generating material (such as the tobacco material described herein) and releases flavor compounds, resulting in an aerosol that is reported to be more similar to FMC aerosols.

[0164] By using an aerosol supply system comprising a coil as described herein (for example, an induction coil that heats at least a portion of the aerosol-generating material to at least 200°C, more preferably at least 220°C), it may be possible to generate aerosols from aerosol-generating materials having certain properties that are considered to be more similar to FMC products. For example, when an aerosol-generating material (containing nicotine) is heated for 2 seconds using an induction heater heated to at least 250°C under an airflow of at least 1.50 L / m during that period, one or more of the following properties have been observed.

[0165] At least 10 μg of nicotine is aerosolized from the aerosol-generating material.

[0166] The weight ratio of the aerosol-forming material to nicotine in the generated aerosol is at least about 2.5:1, preferably at least 8.5:1.

[0167] At least 100 μg of aerosol-forming material can be aerosolized from the aerosol-generating material.

[0168] The average particle size or average droplet size in the generated aerosol is less than approximately 1000 nm.

[0169] The density of the aerosol is at least 0.1 μg / cc.

[0170] In some cases, at least 10 μg of nicotine, preferably at least 30 μg or 40 μg of nicotine, is aerosolized from the aerosol-generating material under an airflow of at least 1.50 L / m during the above period. In some cases, less than approximately 200 μg, preferably less than approximately 150 μg, or less than approximately 125 μg of nicotine is aerosolized from the aerosol-generating material under an airflow of at least 1.50 L / m during the above period.

[0171] In some cases, the aerosol contains at least 100 μg of aerosol-forming material, and under an airflow of at least 1.50 L / m during the above period, at least 200 μg, 500 μg, or 1 mg of aerosol-forming material is preferably aerosolized from the aerosol-generating material. The aerosol-forming material may contain glycerol or may consist of glycerol.

[0172] As defined herein, the term “mean particle or droplet size” refers to the average size of the solid or liquid components of an aerosol (i.e., components suspended in the gas). If the aerosol contains suspended droplets or suspended solid particles, this term collectively refers to the average size of all components.

[0173] Depending on the circumstances, the average particle size or average droplet size of the generated aerosol may be approximately 900 nm, 800 nm, 700 nm, 600 nm, 500 nm, 450 nm, or less than 400 nm. Depending on the circumstances, the average particle size or average droplet size may be approximately 25 nm, 50 nm, or greater than 100 nm.

[0174] In some cases, the density of the aerosols generated during the above period is at least 0.1 μg / cc. In some cases, the density of the aerosols is at least 0.2 μg / cc, 0.3 μg / cc, or 0.4 μg / cc. In some cases, the density of the aerosols is approximately 2.5 μg / cc, 2.0 μg / cc, 1.5 μg / cc, or less than 1.0 μg / cc.

[0175] The non-combustible aerosol supply device is preferably configured to heat the aerosol-forming material 21 of article 1 to a maximum temperature of at least 160°C. The non-combustible aerosol supply device is configured to heat the aerosol-forming material 21 of article 1 to a maximum temperature of at least about 200°C, at least about 220°C, or preferably at least about 240°C, and more preferably at least about 270°C, at least once during the heating process followed by the non-combustible aerosol supply device.

[0176] The use of an aerosol supply system comprising a coil as described herein (for example, an induction coil that heats at least a portion of the aerosol-generating material to at least 200°C, more preferably at least 220°C) makes it possible to generate aerosols from the aerosol-generating material in the article 1 as described herein, where the aerosol is hotter than with conventional devices when it exits the mouth-side end of the mouthpiece 10, thus contributing to the generation of aerosols that are considered to be closer to FMC products. For example, the maximum aerosol temperature measured at the mouth-side end of article 10 can preferably be greater than 50°C, more preferably greater than 55°C, and even more preferably greater than 56°C or 57°C. As an addition or alternative, the maximum aerosol temperature measured at the mouth-side end of article 10 can be less than 62°C, more preferably less than 60°C, and even more preferably less than 59°C. In some embodiments, the maximum aerosol temperature measured at the mouth-side end of article 10 can preferably be between 50°C and 62°C, more preferably between 56°C and 60°C.

[0177] Figure 3 shows an example of a non-combustible aerosol supply device 100 that generates an aerosol from an aerosol-generating medium / material such as the aerosol-generating material 21 of Article 1 described herein. Generally, the device 100 may be used to heat a replaceable article 110 containing an aerosol-generating medium (e.g., Article 1 described herein) to generate an aerosol or other aspirable medium for the user of the device 100 to inhale. The device 100 and the replaceable article 110 together constitute a non-combustible aerosol supply system.

[0178] The device 100 includes a housing 102 (in the form of an outer cover) that encloses and houses various components of the device 100. The device 100 has an opening 104 at one end through which an article 110 can be inserted and heated by a heating assembly. When in use, the article 110 may be inserted all or partly into the heating assembly and heated by one or more components of the heating assembly. When the article 110 is inserted into the device 100, the shortest distance between one or more components of the heating assembly and the tubular elements of the article 110 may be in the range of 3 mm to 10 mm (for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm).

[0179] The device 100 in this example includes a first end member 106, the first end member 106 having a lid 108 that is movable relative to the first end member 106 to close the opening 104 when the article 110 is not in place. In Figure 3, the lid 108 is shown in an open configuration, but it can also be moved to a closed configuration. For example, the user may slide the lid 108 in the direction of arrow "B".

[0180] Furthermore, device 100 may include a user-operable control element 112, such as a button or switch, which operates device 100 when pressed. For example, the user may turn on device 100 by operating the switch 112.

[0181] Furthermore, device 100 may include electrical components, such as a socket / port 114, that can receive a cable and charge the battery of device 100. For example, the socket 114 may be a charging port, such as a USB charging port.

[0182] Figure 4 shows the device 100 of Figure 3 with the outer cover 102 removed and the article 110 absent. The device 100 defines a longitudinal axis 134. As shown in Figure 4, the first end member 106 is located at one end of the device 100, and the second end member 116 is located at the opposite end of the device. The first and second end members 106 and 116 together define at least partially the end face of the device 100. For example, the bottom surface of the second end member 116 defines at least partially the bottom surface of the device 100. The edge of the outer cover 102 may also define part of the end face. In this example, the lid 108 defines part of the top surface of the device 100.

[0183] The end of the device closest to the opening 104 may be known as the proximal end (or mouth end) of the device 100, as it is closest to the user's mouth during use. During use, the user inserts the article 110 into the opening 104 and operates the user control 112 to start heating the aerosol-generating material, utilizing the aerosol generated in the device. This causes the aerosol to flow through the device 100 along the flow path toward the proximal end of the device 100.

[0184] The other end of the device furthest from the opening 104 may be known as the distal end of device 100, as it is the end furthest from the user's mouth during use. When the user utilizes the aerosol generated in the device, the aerosol flows away from the distal end of device 100.

[0185] Device 100 further comprises a power supply 118. The power supply 118 may be a battery, such as a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the heating assembly and supplies power as needed, and heats the aerosol-generating material under the control of a control device (not shown). In this example, the battery is connected to a central support 120 that holds the battery 118 in place.

[0186] The device further comprises at least one electronic module 122. The electronic module 122 may include, for example, a printed circuit board (PCB). The PCB 122 may support at least one control device, such as a processor, and memory. The PCB 122 may also have one or more electrical tracks that electrically connect various electronic components of the device 100. For example, battery terminals may be electrically connected to the PCB 122 so that power can be distributed throughout the device 100. The socket 114 may also be electrically coupled to the battery via an electrical track.

[0187] In exemplary device 100, the heating assembly is an induction heating assembly comprising various components for heating the aerosol-generating material of article 110 by an induction heating process. Induction heating is a process of heating a conductor (such as a susceptor) by electromagnetic induction. The induction heating assembly may comprise an induction element (e.g., one or more inductor coils) and a device for passing a fluctuating current, such as alternating current, through the induction element. The fluctuating current in the induction element generates a fluctuating magnetic field. The fluctuating magnetic field penetrates a susceptor suitably positioned relative to the induction element, generating eddy currents inside the susceptor. Since the susceptor has electrical resistance to eddy currents, the flow of eddy currents against this resistance heats the susceptor by Joule heating. Furthermore, if the susceptor contains a ferromagnetic material such as iron, nickel, or cobalt, heat is also generated by magnetic hysteresis loss in the susceptor, i.e., by the fluctuating orientation of magnetic dipoles in the magnetic material as a result of alignment with the fluctuating magnetic field. In induction heating, compared to, for example, conduction heating, rapid heating is possible because heat is generated inside the susceptor. Furthermore, since no physical contact is required between the induction heater and the susceptor, the degree of freedom in configuration and application is increased.

[0188] The induction heating assembly of the exemplary device 100 comprises a susceptor structure 132 (hereinafter referred to as the “susceptor”), a first inductor coil 124, and a second inductor coil 126. The first and second inductor coils 124 and 126 are made of a conductive material. In this example, the first and second inductor coils 124 and 126 are made of Litz wire / cable that is wound spirally to provide helical inductor coils 124 and 126. The Litz wire comprises a plurality of individual wires that are individually insulated and formed into a single wire by a single twist. The Litz wire is designed to minimize skin effect losses of the conductor. In the exemplary device 100, the first and second inductor coils 124 and 126 are made of copper Litz wire with a rectangular cross-section. In other examples, the Litz wire may have a cross-section of other shapes, such as circular.

[0189] The first inductor coil 124 is configured to generate a first fluctuating magnetic field that heats a first section of the susceptor 132, and the second inductor coil 126 is configured to generate a second fluctuating magnetic field that heats a second section of the susceptor 132. In this example, the first inductor coil 124 is adjacent to the second inductor coil 126 in a direction along the longitudinal axis 134 of the device 100 (i.e., the first and second inductor coils 124 and 126 do not overlap). The susceptor configuration 132 may consist of a single susceptor or two or more separate susceptors. The ends 130 of the first and second inductor coils 124 and 126 are connectable to the PCB 122.

[0190] It should be understood that in some examples, the first and second inductor coils 124 and 126 may have at least one characteristic that is different from each other. For example, the first inductor coil 124 may have at least one characteristic that is different from the second inductor coil 126. More specifically, as an example, the first inductor coil 124 may have a different inductance value than the second inductor coil 126. In Figure 8, the first and second inductor coils 124 and 126 have different lengths such that the portion of the first inductor coil 124 wound around the susceptor 132 is smaller than that of the second inductor coil 126. For this reason, the first inductor coil 124 may have a different number of turns than the second inductor coil 126 (assuming that the spacing between individual turns is substantially the same). In yet another example, the first inductor coil 124 may be made of a different material than the second inductor coil 126. In some examples, the first and second inductor coils 124 and 126 may be substantially identical.

[0191] In this example, the first inductor coil 124 and the second inductor coil 126 are wound in opposite directions. This can be useful when the two inductor coils operate at different timings. For example, the first inductor coil 124 may operate first to heat a first section / part of article 110, and then the second inductor coil 126 may operate later to heat a second section / part of article 110. Winding the coils in opposite directions helps to reduce the current induced in the non-operating coil when used in conjunction with certain types of control circuits. In Figure 4, the first inductor coil 124 is a right-handed helix and the second inductor coil 126 is a left-handed helix. However, in another embodiment, the inductor coils 124 and 126 may be wound in the same direction, or the first inductor coil 124 may be a left-handed helix and the second inductor coil 126 may be a right-handed helix.

[0192] In this example, the susceptor 132 is hollow and therefore defines a receptacle that receives the aerosol-generating material. For example, article 110 can be inserted into the susceptor 132. In this example, the susceptor 120 is tubular with a circular cross-section.

[0193] The susceptor 132 may be composed of one or more materials. Preferably, the susceptor 132 is made of carbon steel having a nickel or cobalt coating.

[0194] In some examples, the susceptor 132 may include at least two materials that can be heated at two different frequencies for selective aerosolization. For example, a first section of the susceptor 132 (heated by a first inductor coil 124) may include a first material, and a second section of the susceptor 132 (heated by a second inductor coil 126) may include a second different material. In another example, the first section may include first and second materials, which can be heated differently based on the operation of the first inductor coil 124. The first and second materials may be adjacent along an axis defined by the susceptor 132, or they may constitute different layers within the susceptor 132. Similarly, the second section may include third and fourth materials, which can be heated differently based on the operation of the second inductor coil 126. The third and fourth materials may be adjacent to each other along the axis defined by the susceptor 132, or they may constitute different layers within the susceptor 132. For example, the third material may be the same as the first material, and the fourth material may be the same as the second material. Alternatively, each material may be different. The susceptor may be made of, for example, carbon steel or aluminum.

[0195] The device 100 in Figure 4 further comprises a thermal insulation member 128 that is generally tubular and can at least partially surround the susceptor 132. The thermal insulation member 128 may be made of any thermal insulation material, such as plastic. In this particular example, the thermal insulation member is made of polyetheretherketone (PEEK). The thermal insulation member 128 can help insulate various components of the device 100 from the heat generated in the susceptor 132.

[0196] Furthermore, the heat insulating member 128 can support all or part of the first and second inductor coils 124 and 126. For example, as shown in Figure 4, the first and second inductor coils 124 and 126 are arranged around the heat insulating member 128 and are in contact with the radially outward surface of the heat insulating member 128. In some examples, the heat insulating member 128 does not abut the first and second inductor coils 124 and 126. For example, a small gap may exist between the outer surface of the heat insulating member 128 and the inner surfaces of the first and second inductor coils 124 and 126.

[0197] In a particular example, the susceptor 132, the heat insulating member 128, and the first and second inductor coils 124 and 126 are coaxial around the central longitudinal axis of the susceptor 132.

[0198] Figure 5 is a partial cross-sectional side view of device 100. In this example, an outer cover 102 is present. The rectangular cross-sectional shapes of the first and second inductor coils 124 and 126 are more clearly visible.

[0199] The device 100 further includes a support portion 136 that engages with one end of the susceptor 132 to hold the susceptor 132 in place. The support portion 136 is connected to the second end member 116.

[0200] The device may also include a second printed circuit board 138 associated with the control element 112.

[0201] Device 100 further comprises a second lid / cap 140 and a spring 142 positioned toward the distal end of device 100. The spring 142 allows access to the susceptor 132 by opening the second lid 140. The user may clean the susceptor 132 and / or support 136 by opening the second lid 140.

[0202] The device 100 further comprises an expansion chamber 144 extending away from the proximal end of the susceptor 132 toward the opening 140 of the device. At least a portion of a retaining clip 146 is disposed within the expansion chamber 144, which contacts and holds the article 110 when received within the device 100. The expansion chamber 144 is connected to the end member 106.

[0203] Figure 6 is an exploded view of the device 100 from Figure 5, with the outer cover 102 omitted.

[0204] Figure 7A shows a cross-section of a portion of the device 100 of Figure 5. Figure 7B shows a magnified view of a region of Figure 7A. Figures 7A and 7B show an article 110 received within the susceptor 132, which is dimensionally defined so that its outer surface abuts against the inner surface of the susceptor 132. This ensures the most efficient heating. The article 110 in this example includes an aerosol-generating material 110a, which is located within the susceptor 132. The article 110 may also include other components such as a filter, packaging material, and / or a cooling structure.

[0205] Figure 7B shows that the outer surface of the susceptor 132 is separated from the inner surfaces of the inductor coils 124 and 126 by a distance of 150, measured perpendicular to the longitudinal axis 158 of the susceptor 132. In a particular example, the distance of 150 is approximately 3mm to 4mm, approximately 3 to 3.5mm, or approximately 3.25mm.

[0206] Figure 7B further shows that the outer surface of the thermal insulation member 128 is separated from the inner surfaces of the inductor coils 124 and 126 by a distance of 152, measured perpendicular to the longitudinal axis 158 of the susceptor 132. In a particular example, the distance 152 is approximately 0.05 mm. In another example, the distance 152 is substantially 0 mm, so that the inductor coils 124 and 126 are in contact with the thermal insulation member 128.

[0207] In one example, the susceptor 132 has a wall thickness 154 of approximately 0.025 mm to 1 mm or approximately 0.05 mm.

[0208] In one example, susceptor 132 has a length of approximately 40mm to 60mm, approximately 40mm to 45mm, or approximately 44.5mm.

[0209] In one example, the insulation member 128 has a wall thickness 156 of approximately 0.25 mm to 2 mm, 0.25 mm to 1 mm, or approximately 0.5 mm.

[0210] When in use, Article 1 described herein can be inserted into a non-combustible aerosol supply device such as the device 100 described with reference to Figures 3 to 7. At least a portion of the mouthpiece 10 of Article 1 may protrude from the non-combustible aerosol supply device 100 and be placed in the user's mouth. An aerosol is generated by heating the aerosol-generating material 21 using the device 100. The aerosol generated by the aerosol-generating material 21 passes through the mouthpiece 10 and enters the user's mouth.

[0212] This method includes the steps of forming an inner body containing a first material (S101) and forming an outer body surrounding the inner body, wherein the resistance of the inner body to gas flow in the longitudinal direction is less than the resistance of the outer body to gas flow in the longitudinal direction.

[0213] In some examples, the step of forming the outer body includes forming the outer body integrally with the inner body.

[0214] In some examples, the step of forming the outer body includes forming the outer body separately from the inner body, and configuring the inner and outer bodies such that the outer body surrounds the inner body.
