Brief Description of the Drawings

[0028] [Figure 1] This is a lateral cross-sectional view of an article used in an aerosol supply system, which includes an aerosol generating material and downstream components of the aerosol generating material. [Figure 2] This is a cross-sectional view of the components in Figure 1, taken along the line X-X'. [Figure 3] This is a lateral cross-sectional view of an article used in an aerosol supply system that includes an aerosol generating material and downstream components of the aerosol generating material (including a flavor delivery member). [Figure 4] This is a flowchart illustrating a method for manufacturing components for articles used in aerosol supply systems. Detailed explanation

[0029] In this specification, the term "delivery system" is intended to include a system for delivering a substance to a user. A combustible aerosol supply system for cigarettes, cigarillos, cigars, and pipe tobacco or homemade or home-rolled cigarette tobacco (whether or not it is based on tobacco, tobacco derivatives, extended tobacco, recycled tobacco, tobacco substitutes, or other smoking materials), A non-combustible aerosol supply system that releases compounds from aerosolizable materials without combustion of the aerosolizable material (such as a hybrid system that generates aerosols by combining electronic cigarettes, tobacco heating products, and aerosolizable materials), Articles comprising aerosolizable material and configured to be used as part of one of these non-flammable aerosol supply systems, An aerosol-free delivery system for lozenges, gums, patches, articles containing inhalable powders, and smokeless tobacco products (e.g., snus and snuff) that deliver materials (which may or may not contain nicotine) to the user without the formation of an aerosol, Includes.

[0030] According to this disclosure, a "flammable" aerosol supply system is one in which the aerosolizable material (or its components) that make up the aerosol supply system is burned in order to facilitate delivery to the user.

[0031] According to this disclosure, a “non-flammable” aerosol supply system is one in which the aerosolizable material (or its components) that constitutes the aerosol supply system is not combusted in order to facilitate delivery to the user. In the embodiments described herein, the delivery system may be a flammable aerosol supply system or a non-flammable aerosol supply system such as a powered non-flammable aerosol supply system.

[0032] The non-flammable aerosol supply systems described herein may include e-cigarettes, also known as vaping devices or electronic nicotine delivery systems (ENDs), but the presence of nicotine in the aerosolizable material is not a requirement.

[0033] The non-combustible aerosol supply system described herein may also include a tobacco heating system, also known as a non-combustion heating system.

[0034] The non-flammable aerosol supply system described herein may be a hybrid system that generates an aerosol by a combination of aerosolizable materials (one of which may be heated, or more of which may 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 a non-tobacco product.

[0035] Typically, a non-flammable aerosol supply system may comprise a non-flammable aerosol supply device and articles used in conjunction with the non-flammable aerosol supply system. However, an article that itself has means for supplying power to an aerosol generating component may itself constitute a non-flammable aerosol supply system.

[0036] A non-flammable aerosol supply device may include a power source and a controller. The power source may be an electrical power source or a heat-generating power source. The heat-generating power source includes a carbon substrate capable of supplying energy in the form of heat to an aerosolizable material or heat transfer material adjacent to the heat-generating power source. Furthermore, a power source such as a heat-generating power source is provided in an article, constituting a non-flammable aerosol supply system.

[0037] In one embodiment, the article used with the non-flammable aerosol supply device may include an aerosolizable material, an aerosol generating component, an aerosol generating area, a mouthpiece, and / or an area for receiving the aerosolizable material.

[0038] In one embodiment, the aerosol generating component is a heater capable of forming an aerosol by interacting with an aerosolizable material, thereby releasing one or more volatile substances from the aerosolizable material. In one embodiment, the aerosol generating component is capable of generating an aerosol from an aerosolizable material without heating. For example, the aerosol generating component may be capable of generating an aerosol from an aerosolizable material without applying heat, for example, by one or more of vibration means, mechanical means, pressurizing means, or electrostatic means.

[0039] In one embodiment, the aerosolizable material may include an active material, an aerosol-forming material, and optionally one or more functional materials. The active material may include (optionally, nicotine contained in tobacco or tobacco derivatives) or one or more other non-olfactory physiologically active materials. The non-olfactory physiologically active materials are materials included in the aerosolizable material that realize physiological reactions other than olfaction.

[0040] 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.

[0041] One or more functional materials may include one or more of the following: fragrances, carriers, pH adjusters, stabilizers, and / or antioxidants.

[0042] In one embodiment, an article used with a non-flammable aerosol supply device may include an aerosolizable material or an area for receiving the aerosolizable material. In one embodiment, an article used with a non-flammable aerosol supply device may include a mouthpiece. The area for receiving the aerosolizable material may be a storage area for storing the aerosolizable material. For example, the storage area may be a reservoir. In one embodiment, the area for receiving the aerosolizable material may be separate from the aerosol generation area or may be combined with the aerosol generation area.

[0043] Aerosolizable material (which may also be referred to herein as 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 aerosolizable material may be in the form of a solid, liquid, or gel, and may or may not contain nicotine and / or flavorings. In some embodiments, the aerosolizable 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 aerosolizable 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.

[0044] The aerosolizable material may be present on the substrate. The substrate may be, for example, paper, cardboard, thick paper, recycled aerosolizable material, plastic material, ceramic material, composite material, glass, metal, or alloy, or may contain these materials.

[0045] Aerosol modifiers are substances that can modify aerosols upon use. Modifiers can alter aerosols to produce physiological or sensory effects on the human body. Exemplary aerosol modifiers include flavorings and sensory substances. Sensory substances generate sensory sensations that can be perceived through the senses, such as coolness or sourness.

[0046] 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)).

[0047] 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)).

[0048] Therefore, a king-size super-slim item would, for example, have a length of approximately 83 mm and a circumference of approximately 17 mm.

[0049] Each type may be produced with mouthpieces of different lengths. The length of the mouthpieces will be approximately 10mm to 50mm (e.g., 15mm to 35mm). The tip paper will be longer than the mouthpiece (e.g., 3 to 15mm or 3 to 12mm) 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 substrate material), connecting the mouthpiece to the rod.

[0050] The articles described herein, as well as the aerosol-generating materials and components thereof, may be constructed in any of the above-described forms, but are not limited thereto.

[0051] 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.

[0052] The filamentous tow materials described herein may include cellulose acetate fiber tow. Furthermore, filamentous tow can 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 filamentous tow may be plasticized with a tow-suitable plasticizer (triacetin in the case of cellulose acetate tow) or left unplasticized. The tow may have any suitable specifications, such as the fibers having a cross-section that is "Y" shaped or "X" shaped, the filament fineness value per filament being 1.5 to 12 denier (e.g., 7 to 10 denier), and the total fineness value being 5,000 to 50,000 (e.g., 10,000 to 40,000).

[0053] 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 includes one or more of ground tobacco, tobacco fibers, loose tobacco, extruded tobacco, tobacco stems, tobacco laminas, remanufactured tobacco, and / or tobacco extracts.

[0054] In this specification, the terms “flavor” and “flavorant” refer to materials that can be used to produce a desired flavor or aroma in products intended for adult consumers, where local regulations permit. One or more flavors may be used as aerosol modifiers as described herein.

[0055] These include extracts (e.g., licorice, hydrangea, magnolia leaf, chamomile, fenugreek, clove, menthol, mint, aniseed, cinnamon, herbs, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-yi) This product contains (oil from orchid, sage, fennel, bell pepper, ginger, anise, coriander, coffee, or any species of mint), flavor enhancers, bitter taste receptor site blockers, sensory receptor site activators or stimulants, sugars and / or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, plant substances, or breath fresheners. These may be imitations, synthetic or natural ingredients, or mixtures thereof. They may be in any preferred form, such as oil, liquid, or powder.

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

[0057] Figure 1 is a lateral cross-sectional view of article 1 used in an aerosol supply system. In this example, article 1 includes a cigarette. However, in alternative embodiments, the same article 1 can be used as an article used in a non-combustible aerosol supply system. Article 1 can be used in a tobacco heating system, also known as a non-combustion heating system. In this case, article 1 preferably comprises an additional cooling element located downstream or upstream of component 4. The cooling element may be a tubular element or may include a tubular element. Paper tubes are preferable as cooling elements because they are relatively easy to manufacture using existing technology and are lightweight components with large internal hollow cavities that aid in cooling. The cooling element may also include one or more openings in the wall of the paper tube or other form of cooling element to aid in the passage of the cooled aerosol through the cooling element.

[0058] Article 1 comprises a cylindrical rod of aerosol-generating material 2 (in this example, tobacco material) and a downstream section 3 connected to the rod 2 downstream of the aerosol-generating material 2. The aerosol-generating material 2 supplies an aerosol when burned (for example, when the rod of the aerosol-generating material 2 is flammable). In other embodiments, Article 1 may constitute a non-flammable aerosol supply system by being used within a non-flammable aerosol supply device. Alternatively, Article 1 may constitute an aerosol supply system without requiring a separate aerosol supply device by having its own heat source. An example of a non-flammable aerosol supply system is the tobacco heating system, also known as a non-combustion heating system, mentioned above.

[0059] The downstream section 3 comprises a component 4 including a material body 5 wrapped in packaging material 6 (in this example, a plastic wrap). The material constituting the body 5 can be distributed substantially uniformly throughout the entire volume of the body 5, for example, in terms of its density.

[0060] Figure 2 is a cross-sectional view of component 4 in Figure 1 taken along the line X-X'. Component 4 is shown separated from the rest of article 1 and comprises a material body 5 and packaging material 6. As shown, the material body 5 is formed from corrugated and gathered material sheets 7. The sheets 7 are gathered laterally to form a body 5 having a roughly cylindrical shape.

[0061] Sheet 7 has a permeability of approximately 1,000 to 50,000 cholesta units (in some examples, approximately 5,000 to 50,000 cholesta units). This level of permeability is advantageous because it is known to result in a more uniform dispersion of the material constituting the body 5, and the likelihood of channel formation extending longitudinally through the body 5 is reduced. Therefore, for a given weight of sheet material 7, higher permeability increases the pull-out resistance in the longitudinal direction of the body 5. This means that material can be saved by using sheet material 7 with a lower average density in the body 5 to achieve the desired pull-out resistance. In addition, sheet material 7 with high permeability has a more open structure, so in the case of biodegradable materials, the decomposition time of component 4 may be shortened. If the additive is applied to the sheet material 7 in liquid form, higher permeability can also increase the absorbency of the sheet material 7, so more additive can be applied to a given weight of material.

[0062] The air permeability of material sheet 7 can be measured in accordance with the international standard ISO 2965:2009, as is known to those skilled in the art.

[0063] Biodegradability can be measured according to the procedure specified in ISO 14855. The components described herein (including component 4 in Figures 1 and 2 and component 4' in Figure 3) can achieve more than 50% biodegradation in 30 days when exposed to fresh or seawater.

[0064] The sheet 7 may have an air permeability of about 1,000 to about 10,000 Gurley units (in some examples, about 2,000 to about 8,000 Gurley units). In other examples, the sheet 7 may have an air permeability of about 5,000 to about 12,000 Gurley units.

[0065] In this example, the body 5 is formed by a single collected material sheet 7. However, in an alternative example, the body 5 may be formed by a plurality of material sheets 7 that are integrally collected to form the body 5. Each of the plurality of material sheets may have the same or different characteristics (e.g., their respective dimensions, air permeability, thickness, basis weight, and composition).

[0066] The material sheet 7 (or, if necessary, a plurality of material sheets) may have an average bulk density of about 0.05 to about 0.5 gms / cm 3 over the entire body 5. In some examples, the material sheet 7 (or, if necessary, a plurality of material sheets) has an average bulk density of about 0.05 to about 0.35 gms / cm 3 , about 0.1 to about 0.3 gms / cm 3 , about 0.16 to about 0.25 gms / cm 3 , or about 0.2 to about 0.25 gms / cm 3 over the entire body 5. In some examples, one or more material sheets constituting the material body have an average density of about 0.1 to about 0.25 gms / cm 3 or about 0.16 to about 0.2 gms / cm 3 The bulk density can be calculated by obtaining the total weight of the body 5 including any additives within the body excluding the capsules as described herein, and dividing the result by the volume defined by the outer surface of the body 5 excluding the weight of any wrapper around the body 5.

[0067] One or more sheets 7 constituting the main body 5 can be formed from cellulose material. For example, one or more sheets can be sheets of paper, sheets of tobacco material, sheets of non-tobacco plant material, or a combination thereof. One or more sheets 7 constituting the main body 5 may have a basis weight of about 20 to about 80 gsm, about 30 to about 50 gsm, about 36 to about 45 gsm, or about 55 to about 75 gsm. Alternatively or additionally, one or more sheets may have a non-corrugated thickness of about 50 μm to about 500 μm, about 50 μm to about 350 μm, about 60 μm to about 300 μm, or about 60 μm to about 160 μm.

[0068] The material body 5 may have a weight of approximately 5 mg to approximately 15 mg per 1 mm of length, approximately 8 mg to approximately 12 mg per 1 mm of length, or approximately 10 mg per 1 mm of length.

[0069] The packaging material 6 preferably has a basis weight of approximately 30 to 75 gsm or approximately 40 to 65 gsm. Such a basis weight is greater than that of typical use and can help improve the roundness of the cross-section of the material body 5.

[0070] If an aerosol-modifying additive is provided to one or more material sheets 7, at least one additive selected from 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 (TEC), triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, propylene carbonate, polyethylene glycol (PEG), tetra(ethylene glycol) diacrylate (TEGDA), or alkyl ketene dimer (AKD) is possible.

[0071] The aerosol-modifying additive may comprise about 7% to about 20% or about 9% to about 18% of the weight of one of the further sheets measured on a dry weight basis. The aerosol-modifying additive may be applied to one or more material sheets as a liquid having a viscosity of 5 to 100 centipoise at 25°C.

[0072] Preferably, one or more material sheets 7 have a combined width of approximately 100 mm to approximately 350 mm or approximately 120 mm to approximately 300 mm. Such a relatively large width provides a large surface area for the application of aerosol-modifying additives as needed, while enabling the formation of a rod with sufficient hardness.

[0073] One or more sheets 7 can improve the overall stiffness of the body 5 by corrugation. At least one of the further sheets 7 extending through the body 5 may include a corrugated sheet material formed to have a corrugated pattern comprising a series of substantially parallel peaks and grooves. The average spacing between adjacent peaks can be greater than about 0.3 mm. Alternatively or additionally, the average depth or amplitude of the peaks and grooves is about 0.1 mm to about 0.8 mm.

[0074] The waveform can be applied using a roller surface with a temperature above 30°C, above 40°C, or above 50°C.

[0075] In this example, article 1 has a circumference of approximately 24.5 mm (i.e., the article is of the regular type). In other examples, the article can be provided in any of the types described herein (for example, with a circumference of 15 mm to 25 mm (e.g., 20 mm to 23 mm)). In this example, component 4 has a length of 27 mm. In an alternative embodiment, component 4 may have any length in the range of approximately 7 mm to approximately 35 mm (e.g., approximately 8 mm to approximately 20 mm).

[0076] Since the outer circumference of component 4 is substantially the same as the outer circumference of the rod of the aerosol-generating material 2, the transition between these components is smooth. In this example, the outer circumference of component 4 is approximately 24.3 mm.

[0077] In this example, the chip paper 8 is wrapped around the entire length of component 4 and a portion of the rod of the aerosol generating material 2, and an adhesive is provided on its inner surface to connect component 4 and rod 2. In this example, the chip paper 8 extends 5 mm on the rod of the aerosol generating material 2, but as an alternative, the component 4 and rod 3 can be securely connected by extending 3 mm to 15 mm or 4 mm to 6 mm on rod 2.

[0078] In this example, the rod of the aerosol generating material 2 is wrapped in a wrapper 10. The wrapper 10 can be, for example, a paper foil wrapper or a paper-backed foil wrapper for use with an article in conjunction with a non-flammable aerosol supply device.

[0079] In this example, Article 1 has a ventilation level through which approximately 40% of the aerosol is drawn in. In an alternative embodiment, Article 1 may have a ventilation level through which 0% to 90% (e.g., 20% to 75%) of the aerosol is drawn in. This ventilation is provided directly to component 4 of Article 1. In this example, Article 1 is provided with first and second parallel perforations 12 through the chip material 8 and packaging material 6, providing ventilation to the main body 5. In this example, the perforations 12 are formed as laser perforations at positions approximately 18 mm and 19 mm, respectively, from the downstream end 2b of the downstream section 3. In an alternative embodiment, this ventilation can be provided elsewhere in the downstream section 3. As previously stated, this ventilation can be provided to the cooling element of Article 1, in which case the Article is used in a non-flammable aerosol supply system such as a cigarette heating system.

[0080] The hardness of component 4 at its longitudinal center point is preferably in the range of approximately 60% to approximately 95% or approximately 70% to approximately 95%.

[0081] The hardness of component 4 may be measured according to the following procedure.

[0082] The measurement may be performed using any suitable device, such as a Borgwaldt Hardness Tester H10.

[0083] Hardness is defined as the ratio between the height h0 of the body and the height h1 of the body under a specified load, and is expressed as a percentage of h0. Hardness can be expressed as follows: Hardness=(h1 / h0)×100 For individual bodies or bodies included in a multi-part rod, hardness measurement is performed at the longitudinal center point of the body.

[0084] A load bar is used to apply the specified load to the main body. The length of the load bar should be considerably larger than the sample being measured. Before hardness measurement, the main body being measured is conditioned for a minimum of 48 hours according to ISO 3402, and during measurement, it is maintained under environmental conditions in accordance with ISO 3402.

[0085] To perform the hardness measurement, the device is placed in the Hardness Tester H10, a preliminary load of 2g is applied to the device, and the initial height h0 of the device under the 2g preliminary load is recorded after 1 second. Then the preliminary load is removed, and a load bar with a load of 150g is lowered onto the sample at a speed of 0.6mm / s, and the height h1 of the device under the 150g load is measured after 5 seconds.

[0086] The hardness is determined as the average hardness of at least 20 body or other components measured according to this procedure.

[0087] The closed pressure drop across the entire component 4 can be approximately 1.5 mmWG to approximately 8.6 mmWG / mm (length of component 4) or approximately 3 mmWG to approximately 6 mmWG / mm (length of component 4). The closed pressure drop is the pressure drop measured along the length of component 4 with any ventilation opening closed. ISO 6565:2015, an ISO standard familiar to those skilled in the art, can be used to measure the closed pressure drop.

[0088] The tensile strength of one or more sheets in the longitudinal (mechanical) direction, as measured according to ISO 1924-2:2008, is preferably greater than about 10 N / 30 mm, and can be about 20 to about 100 N / 30 mm or about 25 to about 80 N / 30 mm. The elongation of one or more sheets in the longitudinal (mechanical) direction, as measured according to ISO 1924-2:2008, is preferably less than 5% (e.g., about 0.5% to about 4% or about 0.9% to about 2.5%). The same tensile strength and elongation range may apply in the transverse (crossing) direction across the entire width of one or more sheets.

[0089] Figure 3 is a side cross-sectional view of article 1' used in an aerosol supply system including an aerosol generating material 2 and a downstream component 4' of the aerosol generating material 2. Article 1' is the same as article 1 described with reference to Figures 1 and 2, except that the component 4' in the downstream section 3' of Figure 3 further comprises a flavor delivery member 9.

[0090] The flavor delivery member 9 delivers flavors or flavorings as described herein to aerosols passing through the component 4'. In this example, the flavor delivery member 9 is embedded in one or more material sheets 7 of the main body 5' and is completely surrounded by one or more material sheets 7. As an alternative to the flavor delivery member, an additive other than a flavoring may be provided in a component otherwise identical to that described herein. This additive may be, for example, one of the aerosol modifying additives or aerosol modifying agents described herein.

[0091] The flavor delivery member 9 may include capsules. In some embodiments, the flavor delivery member 9 includes first and second capsules.

[0092] In some embodiments, the above-described capsule 9 comprises an outer shell and an inner core.

[0093] The shell of each capsule 9 may be solid at room temperature. The shell may contain alginate, consist of alginate, or be essentially composed of alginate. However, in alternative embodiments, it shall be recognized that the shell is formed of different materials. For example, alternatively, the shell may contain gelatin, carrageenan, or pectin, consist of gelatin, carrageenan, or pectin, or be essentially composed of gelatin, carrageenan, or pectin. The shell may contain one or more of alginate, gelatin, carrageenan, or pectin, consist of one or more of alginate, gelatin, carrageenan, or pectin, or be essentially composed of one or more of alginate, gelatin, carrageenan, or pectin.

[0094] The shell of each additive capsule may be impermeable to, or substantially impermeable to, the core flavoring or stimulant, or other activating agent. Therefore, the shell initially prevents the core activating agent from escaping the capsule. If the user desires aerosol denaturation, the activating agent is released by the rupture of one or more capsule shells.

[0095] In some embodiments, the above or each capsule has a diameter in the range of 1 to 5 mm, preferably in the range of 2 to 4 mm. In some embodiments, the diameter of the above or each capsule is about 3 mm to 3.5 mm. The above or each capsule may be roughly spherical. In other examples, other shapes and sizes of capsules may be used.

[0096] The total weight of each capsule may be in the range of about 5 mg to about 50 mg, preferably in the range of about 10 to 30 mg. In some embodiments, the weight of each capsule is about 14 mg.

[0097] In some embodiments, the above or each capsule is centered on the longitudinal axis of the component 4'.

[0098] As described above, each capsule may have a core-shell structure. That is, a core containing a fragrance or another aerosol modifier is surrounded by an encapsulating or barrier material forming a shell. The shell structure prevents the aerosol modifier from moving during storage of the article, while allowing for the controlled release of the aerosol modifier (also called an aerosol modifier) ​​during use.

[0099] In some cases, the barrier material (also referred to herein as the encapsulating material) is fragile. The above or each capsule is crushed, shattered, or destroyed by the user to release the encapsulated aerosol modifier. Typically, one or more of the capsules are destroyed immediately before the start of heating, but the user can also choose the timing of the release of the aerosol modifier from the capsules. The user can then choose to destroy the other capsules later (for example, after the start of heating). The user may choose to destroy one of the other capsules when a portion of the aerosol has been released from the aerosol generating material, so that the remaining aerosol generating material is modified by the aerosol modifier in the other capsule. Alternatively, the user may choose to destroy multiple capsules simultaneously.

[0100] The term "breakable capsule" refers to a capsule whose shell is breakable by pressure that releases the core. More specifically, the shell can rupture due to pressure applied by a user's fingers when they wish to release the capsule's core.

[0101] In some cases, the barrier material is heat-resistant. That is, in some cases, the barrier will not rupture, melt, or malfunction at temperatures reached at the capsule portion during the operation of the aerosol supply device in which Article 1 is used. For example, the capsule placed in the Article may be exposed to temperatures in the range of, for example, 30°C to 100°C, and the barrier material may be designed to retain the liquid core up to at least about 50°C to 120°C.

[0102] In other cases, the above-mentioned capsules or each capsule release the core composition upon heating, for example, by capsule expansion leading to the melting or rupture of the barrier material.

[0103] The total weight of each capsule may be in the range of approximately 1 mg to approximately 100 mg, preferably approximately 5 mg to approximately 60 mg, approximately 8 mg to approximately 50 mg, approximately 10 mg to approximately 20 mg, or approximately 12 mg to approximately 18 mg.

[0104] The total weight of the core formulation may be in the range of approximately 2 mg to approximately 90 mg, preferably approximately 3 mg to approximately 70 mg, approximately 5 mg to approximately 25 mg, approximately 8 mg to approximately 20 mg, or approximately 10 mg to approximately 15 mg.

[0105] In some embodiments, the above-described or each capsule comprises a core and shell as described above. Each capsule may exhibit a crushing strength of about 4.5 N to about 40 N, more preferably about 5 N to about 30 N or about 28 N (e.g., about 9.8 N to about 24.5 N). The capsule burst strength of each capsule can be measured by using a force gauge that measures the force required to burst a capsule pressed between two flat metal plates when the capsule is removed from the material body 6. A preferred measuring device is a Sauter FK 50 force gauge having a mounting portion with a flat head, the mounting portion being usable to crush the capsule against a flat, hard surface having a surface similar to that of the mounting portion.

[0106] The above or each capsule may be substantially spherical and may have a diameter of at least about 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 2.0 mm, 2.5 mm, 2.8 mm, or 3.0 mm. The above or each capsule may have a diameter less than about 10.0 mm, 8.0 mm, 7.0 mm, 6.0 mm, 5.5 mm, 5.0 mm, 4.5 mm, 4.0 mm, 3.5 mm, or 3.2 mm. For example, the diameter of the capsule may be in the range of about 0.4 mm to about 10.0 mm, about 0.8 mm to about 6.0 mm, about 2.5 mm to about 5.5 mm, or about 2.8 mm to about 3.2 mm. In some cases, the diameter of each capsule may be about 3.0 mm. These sizes are particularly suitable for incorporating the capsules into articles such as those described herein.

[0107] While only single material bodies 5, 5' have been described with reference to the drawings, in alternative embodiments, components 4, 4' in Figures 1, 2, and 3 may comprise additional parts, such as additional material bodies or other parts like tubular sections. The additional parts may be upstream or downstream of components 4, 4', or both upstream and downstream, and may be formed from any material suitable for use in the articles described herein. For example, additional parts formed by filamentous tows as defined herein may be provided upstream or downstream of material bodies 5, 5', or both upstream and downstream. The (one or more) additional parts may be provided as material bodies, or in other forms such as tubular shapes (including hollow tubular sections upstream and / or downstream of bodies 5, 5').

[0108] Figure 4 is a flowchart illustrating a method for manufacturing components for articles used in an aerosol supply system.

[0109] In step S101, one or more material sheets are supplied along a transport path, and each sheet has a permeability of approximately 1,000 to approximately 50,000 cholesta units (e.g., approximately 5,000 to approximately 50,000 cholesta units). The transport path may be a path between rollers that guide one or more sheet materials into a rod forming machine. In step S102, one or more sheets are formed into a rod. One or more sheets may be first corrugated and then collected together to form a rod. In step S103, the rod is wrapped in a wrapper, and in step 104, the rod is cut to form components.

[0110] As one or more sheets are supplied along the transport path, an aerosol modification additive or aerosol modifier may be applied to one or more sheets. In this case, the aerosol modification additive may be applied, for example, as a liquid having a viscosity of 5 to 100 centipoise at 25°C.

[0111] Furthermore, this method may include corrugating one or more material sheets using a roller surface at a temperature above 30°C, above 40°C, or above 50°C.
