Description

[Technical Field]

[0001] This disclosure relates to aerosol-generating compositions, methods for producing aerosol-generating materials, and articles containing aerosol-generating materials. [Background technology]

[0002] Aerosol supply products generate an aerosol during use, which is inhaled by the user. For example, a cigarette heating device forms an aerosol by heating an aerosol-generating material, such as a cigarette, rather than burning the base material. Such an aerosol supply product generally includes an aerosol-generating section or region that generates an aerosol during use, and a mouthpiece through which the aerosol passes and reaches the user's mouth.

[0003] However, such aerosol-generating materials need improvement in terms of both their flavor delivery, ease of manufacture, and their format within delivery devices. [Overview of the project]

[Figure 5] This is a side cross-sectional view of the article shown in Figure 4. [Modes for carrying out the invention]

[0028] As used herein, the term “delivery system” is intended to encompass a system for delivering at least one substance to a user. Combustion aerosol supply systems for cigarettes, cigarillos, cigars, and tobacco for pipes, hand-rolled cigarettes, or homemade cigarettes (whether based on tobacco, tobacco derivatives, extended tobacco, reconstituted tobacco, tobacco substitutes, or other smokeable materials), Non-combustion aerosol supply systems that release compounds from aerosol-generating materials without burning the materials, such as hybrid systems that generate aerosols using a combination of electronic cigarettes, tobacco heating products, and aerosol-generating materials, and An aerosol-free delivery system for delivering at least one substance to a user orally, nasally, transdermally, or by another method that does not form an aerosol, including but not limited to oral products such as lozenges, gums, patches, articles containing inhalable powders, and oral tobacco containing snus or wet snuff, wherein at least one substance may or may not contain nicotine. Includes.

[0029] According to this disclosure, a “non-combustible” aerosol supply system is a system in which the aerosol-generating materials (or their components) that make up the aerosol supply system are not burned or incinerated in order to facilitate the delivery of at least one substance to the user.

[0030] In some embodiments, the delivery system is a non-combustible aerosol supply system, such as a powered non-combustible aerosol supply system.

[0031] In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), but it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0032] In some embodiments, the non-combustion 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 cigarette heating system.

[0033] In some embodiments, the non-combustible aerosol supply system is a hybrid system that generates an aerosol using a combination of aerosol-generating materials, one or more of which may be heated. Each of the aerosol-generating materials may be, for example, in the form of a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product.

[0034] Typically, a non-combustible aerosol supply system may comprise a non-combustible aerosol supply device and articles for use with the non-combustible aerosol supply device.

[0035] In some embodiments, the disclosure relates to articles comprising an aerosol-generating composition and configured for use with a non-combustible aerosol supply device. These articles may be referred to as consumables throughout the disclosure.

[0036] In some embodiments, a non-combustible aerosol supply system, such as the non-combustible aerosol supply device THP, may include a power source and a controller. 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 to which energy can be supplied to distribute power in the form of heat to an aerosol-generating material or heat-transferring material located near the heat-generating power source.

[0037] In some embodiments, the non-combustion aerosol supply system may include an area for receiving articles, an aerosol generator, an aerosol generation area, a housing, a suction port, a filter and / or an aerosol modifier.

[0038] In some embodiments, articles for use with a non-combustible aerosol supply device may include an aerosol generating composition, an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generator, an aerosol generating area, a housing, packaging material, a filter, a suction nozzle and / or an aerosol modifier.

[0039] In some embodiments, the delivered substance may be an aerosol-generating material or a material not intended for aerosolization. Optionally, any of the materials may include one or more active ingredients, one or more flavorings, one or more aerosol-forming materials, and / or one or more other functional materials.

[0040] In a first aspect of the present invention, an aerosol-generating composition is provided which comprises one or more extruded strands of an aerosol-generating material, wherein the one or more extruded strands of the aerosol-generating material have length, width and height, the width and height are substantially the same, and the length is greater than the height or width.

[0041] The strands of the aerosol-generating material have longitudinal dimensions. Figure 1 shows a specific embodiment in which the strands have a circular cross-section. The dimensions described herein are marked thereon.

[0042] As used herein, the term “length” refers to the longest dimension in the direction of the longitudinal dimension of the strand. In embodiments where the strand is not linear, but wavy or irregular in orientation, the length refers to the dimension in the direction of the longitudinal axis of the strand as the strand would be in a linear form. In Figure 1, the length of an exemplary embodiment of the strand is indicated as “L”, and the strand is in the linear form described above.

[0043] As used herein, the term “width” refers to a dimension in a direction or plane that transverses the longitudinal dimension according to the present invention. In some embodiments, width may refer to a dimension in a direction or plane perpendicular to the longitudinal dimension. In Figure 1, the width of an exemplary embodiment of the strand is indicated as “W”.

[0044] As used herein, the term “height” refers to a dimension that spans the length and width dimensions. In some embodiments, width may refer to a dimension in a direction or plane perpendicular to the longitudinal dimension. In Figure 1, the height of an exemplary embodiment of the strand is indicated as “H”.

[0045] In some embodiments, the height of one or more stands is approximately 0.1 to 5 mm. In some embodiments, the height of one or more stands is approximately 0.3 to 4 mm, approximately 0.5 to 2 mm, or approximately 0.8 to 1.5 mm. In some embodiments, the height of one or more stands is approximately 0.8 to 1.2 mm. In some embodiments, the height of one or more stands is approximately 1 mm. In some embodiments, the height of one or more stands is approximately 0.2 to 0.4 mm. In some embodiments, the height of one or more stands is approximately 200 to 300 μm.

[0046] In some embodiments, the width of one or more stands is approximately 0.1 to 5 mm. In some embodiments, the width of one or more stands is approximately 0.5 to 4 mm, approximately 0.8 to 2 mm, or approximately 0.9 to 1.5 mm. In some embodiments, the width of one or more stands is approximately 0.8 to 1.2 mm. In some embodiments, the width of one or more stands is approximately 1 mm. In some embodiments, the width of one or more stands is approximately 200 to 400 μm, or approximately 245 to 250 μm. In some embodiments, the width of one or more stands is approximately 200 to 300 μm.

[0047] Preferably, the strands may have a smaller width or height compared to other aerosol-generating materials. While we do not wish to be bound by any particular theory, since the strands are formed via a die, it is conceivable that the die can be made smaller or larger to produce strands with particularly small or large widths and / or heights. Other aerosol-generating materials may be formed as sheets and sliced, which prevents the formation of small widths and / or heights.

[0048] The height and width may be selected to provide an appropriate surface area-to-volume ratio for flavoring the user. The height and width may also be selected to provide malleable strands that can be manipulated and positioned within the article. The height and width may further be selected to provide appropriate packing within the article.

[0049] Height and width also determine the thickness of the strand. Relatively thicker strands may be more difficult to manufacture. However, if the strand is too thin, it may easily tear during and after the manufacturing process.

[0050] The height and width are approximately the same. For example, the height-to-width ratio may be about 1:0.5 to about 1:5. In some embodiments, the height-to-width ratio may be about 1:0.8 to about 1:1.5, or about 1:0.9 to about 1.2. In some embodiments, the height-to-width ratio may be about 1:1. As described herein, the feature of strands having approximately the same height and width may be a result of the shape of the strand's cross-section and the extrusion process.

[0051] In some embodiments, the length of one or more stands is approximately 6 to approximately 34 mm. In some embodiments, the length of one or more stands is at least approximately 6, at least approximately 12, and at least approximately 20 mm. In some embodiments, the length of one or more stands is up to approximately 14, up to approximately 20 mm, up to approximately 34, and up to approximately 72 mm. In some embodiments, the length of one or more stands is approximately 12 to approximately 34 mm. The length may be selected to suitably fit the article or aerosol generating section. For example, the length of the strand may be the same as or less than the length of the article or aerosol generating section. This means that the strands can be aligned with each other while inside the article or aerosol generating section. In another example, the strand is longer than the length of the article or aerosol generating section, in which case the strand may be operated differently to fit the article or aerosol generating section, for example, by folding.

[0052] The length is greater than the height or width of the strand. In some embodiments, the length-to-height ratio can be about 1:1000 to about 1:5. In some embodiments, the length-to-height ratio can be about 1:100 to about 1:10. This creates the overall shape of the strand. The larger the length-to-height ratio, the more elongated the strand becomes.

[0053] In some embodiments, one or more strands are approximately the same length. In such embodiments, the strands may be easier to manufacture because they can be cut at regular intervals. In some embodiments, one or more strands are of different lengths. This may facilitate packing into articles.

[0054] In some embodiments, one or more strands may have different lengths, heights, or widths. For example, the aerosol-generating composition may include a portion of a strand having a first size or size range and one or more other portions of a strand having a second different size or size range. In some embodiments, the aerosol-generating composition may include one or more extruded strands of substantially the same length.

[0055] In some embodiments, one or more extruded strands are in the form of a continuous strand. Therefore, the aerosol-generating composition comprises one or more extruded strands in the form of a continuous strand. In such embodiments, the strands can be extruded continuously to form a continuous strand configuration. In some embodiments where one or more extruded strands are in the form of a continuous strand, the strands may be folded within the article. Alternatively, the strands may be cut into shorter, discontinuous strands.

[0056] The extrusion stand may have any suitable shape and may have any suitable cross-section. In some embodiments, one or more extrusion stands have an elongated shape formed from the extrusion process.

[0057] In some embodiments, the cross-section of one or more extruded strands is selected from the group including circular, semicircular, crescent, Y-shaped, and star-shaped. This offers the advantage that gaps may exist between the strands within the article, allowing air or vapor to move more freely within the article. As a result, the pressure drop during use is improved, and the intensity and lifespan of the flavor generated from the strands can be increased. The cross-section of the strands may be selected to increase the volume-to-surface area ratio, thereby further improving the intensity and lifespan of the flavor generated from the strands. A Y-shaped cross-sectional shape is considered particularly beneficial because it can provide an optimal surface area-to-volume ratio.

[0058] In some embodiments, the strands have a cross-sectional shape that allows the strands to "interlock" with other strands. For example, a first strand may be configured to interlock with one or more other strands. In such embodiments, the strands may interlock with each other at least partially. This can increase the packing density of the aerosol-generating composition, making it possible to pack more strands into a given volume of space.

[0059] An example of this embodiment is shown in Figure 2. Figure 2 is a cross-sectional view of article 1 comprising an aerosol generating section 3 in which strands 13 are packed. The cross-section of the strands 13 is crescent-shaped. Article 1 may further comprise packaging material 5 that can be in contact with the aerosol generating section 3 and the strands therein. Due to the shape of the strands, the strands can interlock with each other, thereby allowing more strands to fit together in the aerosol generating section. This can also prevent the strands from moving within the aerosol generating section during transport, storage, or use.

[0060] Packing density affects flavor delivery. As more strands are packed within the article or aerosol-generating section, a stronger flavor may be delivered to the user. In addition, in embodiments where the aerosol-generating composition includes multiple aerosol-generating materials with different compositions, a more complex flavor may be delivered to the user. On the other hand, higher packing density reduces airflow, increasing pressure drop and suction resistance to the user. In some embodiments, the number of strands per article can range from 150 to 340.

[0061] The aerosol-generating composition is approximately 2 cm 3 / g ~ approx. 9cm 3 It may have a packing density of / g. Such a packing density can provide an optimal pressure drop and thus improve sensory characteristics.

[0062] The cross-section of the strands may also be selected to prevent interlocking of the aerosol-generating materials. Such embodiments enjoy the advantages of increasing the density of strands within the article, making the article lighter, and requiring less strand to fill the volume. Some of these embodiments also have the advantage that the movement of the strands within the article is reduced, and they are fixed in place by each other.

[0063] "Fill value" (also known as "filling value") is a measure of a material's ability to occupy a specific volume with a given moisture content. Fill value is measured using a densimeter, which measures the volume occupied by a unit weight of the material or composition. A higher fill value indicates that less material is required to produce a rod with an acceptable hardness / hardness level for a given circumference, volume, and length than is required for a material with a lower fill value.

[0064] In some embodiments, the aerosol-generating material may have a filling value of about 3 to about 8 cc / g, about 4 to about 8 g / cc, or about 4.5 to about 5.5 cc / g.

[0065] The cross-section of the strand is a result of the process by which the strand is manufactured, and the die is shaped to provide the strand with a selected cross-section. The cross-sectional shape of the strand can be formed by changing the shape of the die in the extrusion process described herein. This can also change the density of the strand.

[0066] In some embodiments, the strand may have, or substantially have, a non-rectangular, non-square, or non-cuboidal cross-section. That is, the strand may not have sharp 90° corners.

[0067] Alternatively, in some embodiments, the cross-section of the strand may be rectangular or square. This may be a result of the strand being further cut during the manufacturing process.

[0068] In some embodiments, one or more extruded strands have substantially the same width along their length. In such embodiments, one or more extruded strands have substantially the same cross-section along their length. This offers the advantage of improved flavor consistency to the user. Providing substantially the same cross-section along the length of the strand(s) is thought to provide a consistent surface area-to-volume ratio, thereby providing consistent aerosol generation and consistent flavor delivery.

[0069] The present invention enjoys the advantage that the extrusion process controls the size and shape of the strand. This means that the strands can be uniform, and as a result, the consistency of their flavor can be improved. The strands are more consistent in shape and weight, which is suitable for packing and logistics, preparing materials for consumables or articles. While we do not wish to be bound by a single theory, it is considered that the extrusion process can provide a consistent width and cross-section along the length because it can strictly control the pressure and / or speed at which the material can be pushed through the die, and therefore can be very consistent. This results in a consistent width and cross-section of the resulting strand(s).

[0070] In other manufacturing processes, such as "band casting," the thickness of the final product may vary, which can have unpredictable and variable effects on the properties of the article (e.g., pressure drop). Therefore, the present invention offers advantages over such methods because the extruded strands have a more uniform and predictable shape.

[0071] An aerosol-generating composition comprising one or more extruded strands is formed from an extruded aerosol-generating material. Optionally, one or more extruded strands may be dried, shredded, cut, or further processed.

[0072] In some embodiments, the aerosol-generating material is produced by the steps of forming a mixture, extruding the mixture through a die to form an extruded aerosol-generating material, and cutting the aerosol-generating material to form one or more extruded strands. This method may include some or all of these steps.

[0073] The mixture may be formed by any suitable means. The mixture may be stored before extrusion or extruded immediately. The aerosol-generating material and / or aerosol-generating composition may contain the same components as the mixture. In some embodiments, the aerosol-generating material and / or aerosol-generating composition may contain additional components to the mixture. The components of the aerosol-generating material, aerosol-generating composition and / or mixture are described herein.

[0074] In some embodiments, a method for forming an aerosol-generating material includes the steps of forming a first composition, forming a second composition, combining the first composition and the second composition to form a mixture of the first and second compositions, and extruding the mixture of the first and second compositions to form an aerosol-generating material.

[0075] In some embodiments, the first composition, also known as the “wetting mixture,” comprises an aerosol-forming agent or wetting agent and a binder. The first composition may also comprise other liquids or suspensions disclosed herein. The first composition may be a liquid phase.

[0076] In some embodiments, the second composition, also known as the “dry mixture,” comprises a plant material, a filler, and optionally a second binder. The second composition may also comprise other solids or gels disclosed herein. The second composition may be a solid phase. In some embodiments, the second composition does not contain a binder.

[0077] Once formed and mixed, the mixture can be extruded using any extrusion technique or apparatus known in the art to form an aerosol-generating material.

[0078] The mixture enjoys the advantage that it has a consistency suitable for extrusion and requires a minimum amount of water to achieve this. This has the desirable result of requiring less water to be removed after the extrusion process and therefore less drying. This has the advantages described herein, including reduced flavor loss during the drying process and less energy use.

[0079] Extrusion involves feeding a mixture through an orifice or die to produce extruded aggregates. The process of applying pressure to the precursor composition in combination with shear force results in aggregated structures that may take any shape as described herein.

[0080] Extrusion can be carried out using one of the main classes of extruders: screw, sieve and basket, roll, ram and pin barrel extruders.

[0081] Forming strands by extrusion has the advantage that this process combines mixing, conditioning, homogenization, and molding of the mixture of the first and second compositions.

[0082] In embodiments where the strand contains tobacco, the extrusion process enhanced tobacco similarity, as the manufactured strand may have a texture and preferred notes similar to tobacco.

[0083] Other materials or additives, such as bases, diluents, solid aerosol-forming agents, solid flavor modifiers, leavening agents, and other additives known in the art, may also be added during the extrusion process. This has the advantage that the additives are uniformly distributed throughout the structure being formed. The formed structure may aggregate as a result of the extrusion process.

[0084] In some embodiments, the resulting extruded strands are dried using any suitable drying technique known in the art. For example, microwave, infrared, air, and oven drying are suitable techniques for drying aerosol-generating materials. Water may be removed by evaporating it from the extruded mixture at ambient temperature and pressure (e.g., 25°C and 101 kPa). Alternatively, water can be removed by applying heat to the strand (e.g., by heating it above about 25°C) and / or by lowering the atmospheric pressure surrounding the strand (e.g., below 101 kPa).

[0085] The temperature of the drying step may be less than 100°C, and in some embodiments of the present invention, it may be less than 90°C. The drying temperature used may be up to about 25°C, about 30°C, about 40°C, about 50°C, about 60°C, about 70°C, about 80°C, about 90°C, or about 100°C. The drying temperature may be higher than the ambient temperature. For example, the drying temperature may exceed 15°C, 20°C, or 25°C.

[0086] Low drying temperatures are preferable because they reduce the loss of volatile components such as nicotine, glycerol, and flavors that contribute to the flavor, taste, and texture of the final product. The strands are also dried to provide appropriate texture and strength. For example, overly dried strands can be brittle and lack malleability. On the other hand, if the stand is too wet, it can be sticky and difficult to use in articles.

[0087] The length of the drying step may be up to approximately 5, 10, 30, 45, 60, 90, 120, or 360 minutes.

[0088] The advantage of the extrusion process is that, because the strand has a relatively high surface area-to-volume ratio, the time required to properly dry the strand is shorter. This is a faster manufacturing process that uses less energy and saves energy costs. While we do not wish to be bound by any particular theory, the material can be extruded using less water, and therefore the mixture requires less water. As a result, drying time is shorter, drying temperature is lower, and the appropriate moisture content is achieved.

[0089] The overall moisture content (OV) of the strand also affects its physical properties. For example, if the OV is too low, the strand may not be flexible enough to withstand the processing conditions. For instance, the strand may collapse or decompose during processing. To aid in processing, the aerosol-generating material may be prepared before forming multiple elongated strips of the aerosol-generating material.

[0090] In some embodiments, the mixture contains water in an amount of about 0% to about 15% by weight, about 5% to about 40% by weight, about 30% to about 40% by weight, about 28% to about 34% by weight, or about 30% to about 34% by weight of the mixture.

[0091] In some embodiments, the mixture contains oven-volatile substances in an amount of about 0% to about 15% by weight or about 5% to about 40% by weight of the mixture. In some embodiments, the mixture contains oven-volatile substances in an amount of about 30% to about 40% by weight of the mixture.

[0092] In some embodiments, one or more strands or aerosol-generating materials contain water in amounts of about 0% to about 15%, about 5% to about 40%, about 5% to about 15%, about 6% to about 10%, or about 6% to about 8% of the weight of the one or more strands or aerosol-generating materials. The water content of the strands or aerosol-generating materials affects the flavor delivery and "hot puff" effect that consumers may notice. Therefore, lower water content reduces the "hot puff" which is perceived undesirably. On the other hand, if the water content is too low, the strands may have a brittle texture and may dry out too much.

[0093] In some embodiments, one or more strands or aerosol-generating materials contain oven-volatile substances in amounts of about 0% to about 15%, about 5% to about 20%, about 10% to about 20%, or about 5% to about 15% of the weight of the one or more strands or aerosol-generating materials.

[0094] In some embodiments, where the strand or aerosol-generating material contains nicotine, one or more strands or aerosol-generating materials contain nicotine in an amount of about 0% to about 5% or about 1% to about 3% of the weight of the one or more strands or aerosol-generating materials. In some embodiments, one or more strands contain nicotine in an amount of about 2% of the weight of the one or more strands or aerosol-generating materials.

[0095] In some embodiments, where the strand or aerosol-generating material contains glycerol, one or more strands contain glycerol in an amount of about 10% to about 20% or about 15% to about 18% of the weight of the one or more strands or aerosol-generating material.

[0096] The water content of the aerosol-generating materials described herein may vary, for example, depending on the temperature, pressure, and humidity conditions under which the composition is maintained. The water content can be determined by Karl Fischer analysis, as is known to those skilled in the art.

[0097] Unless otherwise specified, the terms “volatile components,” “volatile substances,” “total volatile,” “volatile substance content,” and “total volatiles” used herein refer to volatile compounds including water. The volatile substance content of a material can be measured as the mass loss when the sample is dried in a forced-draft oven at a temperature adjusted to 110°C ± 1°C for 3 hours ± 0.5 minutes. After drying, the sample is cooled to room temperature in a desiccator for approximately 30 minutes.

[0098] In some embodiments, the strand is cut or sliced ​​after drying. In some embodiments, the strand is not shredded. In some embodiments, the strand is shredded. Extrusion of the mixture to form the strand offers the advantage that the strand is immediately formed to the desired width and height, and therefore no further shredding is required. This is faster and more cost-effective as one step is eliminated from a typical aerosol-generating material manufacturing process. To produce strands of known length, the strand may be cut or sliced ​​horizontally (along the width rather than along the length). The strand may be sliced ​​immediately after extrusion, after drying, or after further processing steps.

[0099] An advantage of the present invention is that the extrusion process provides greater elasticity, enabling the molding of the aerosol-generating composition. The aerosol-generating material is also less brittle, allowing it to be bent to conform to an article.

[0100] In some embodiments, the tensile strength of the aerosol-generating material is at least about 3, 4, 6, 8, 10, 12, or 14 N / 15 mm. In some embodiments, the tensile strength of the aerosol-generating material is at least about 5 N / 15 mm. In some embodiments, the tensile strength of the aerosol-generating material is up to about 15 N / 15 mm. In some embodiments, the tensile strength of the aerosol-generating material is at least about 3, 4, 6, 8, 10, 12, or 14 N / 15 mm. A suitable tensile strength provides the advantage of withstanding processing, manufacturing, storage, and use without significant degradation. Extruded strands can have particularly high tensile strength.

[0101] The elasticity of an aerosol-generating material may also be measured by measuring the amount a strand can stretch before it breaks when pulled in the direction of the strand's length. In some embodiments, the strand stretches to at least about 110% of its length before breaking. In some embodiments, the strand stretches to at least about 104%, at least about 105%, at least about 108%, or at least about 110% of its length before breaking. In some embodiments, the strand can expand by about 4 to about 10%, or about 5 to about 9%. This can be measured as the percentage of strand elongation compared to the initial size at which break occurs.

[0102] Extensibility measures how much a material stretches compared to its original dimensions before it breaks. Extensibility can be measured along the length of a strand(s) and may be measured using a ruler or micrometer. Extensibility is related to elasticity; for example, higher elasticity leads to higher extensibility. In some embodiments, a strand may stretch to about 1 mm, about 2 mm, or about 4 mm before breaking.

[0103] Elasticity or extensibility offers the advantage that strands can be manipulated within the article and during manufacturing. As a result, strands are more robust and easier to handle during manufacturing and storage. While we do not wish to be bound by reasons, the extrusion process is considered to contribute to improved elasticity or extensibility because it allows aerosol-generating materials to be shaped and formed in a way that leads to increased elasticity or extensibility.

[0104] In some embodiments, the aerosol-generating material and / or aerosol-generating composition includes a plant-based material.

[0105] As described herein, plant materials may include or be derived from one or more plant substances or their components, derivatives, or extracts.

[0110] In some embodiments, the plant material comprises or is derived from one or more plant substances or their components, derivatives, or extracts, and the plant substance is tobacco. In some embodiments, the aerosol-generating composition does not contain tobacco. In embodiments, the aerosol-generating composition may contain plant materials that do not contain tobacco or are not derived from tobacco. In such embodiments, the plant material may be selected to be non-tobacco for consumer preference or for regulatory reasons. The plant material may be selected to provide a pleasant or desirable flavor to consumers.

[0111] In some embodiments, the plant material comprises or is derived from one or more plant substances or their components, derivatives, or extracts, the plant substances being selected from eucalyptus, star anise, cocoa, and hemp.

[0112] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may contain different plant substances or their components, derivatives, or extracts. This provides consumers with the advantage of tasting different plant materials. In some embodiments, the plug is close to the mouthpiece end so that different flavors are delivered to the user at different times.

[0113] In some embodiments, the mixture, aerosol-generating material, and / or aerosol-generating composition comprises at least about 10% by weight of a plant substance(s) or its components(s), derivatives(s), or extracts(s). In some embodiments, the mixture, aerosol-generating material, and / or aerosol-generating composition comprises at least 10% by weight, at least about 25% by weight, at least about 30% by weight, at least about 50% by weight, at least about 75% by weight, at least about 95% by weight, or at least about 99% by weight of a plant substance(s) or its components(s), derivatives(s), or extracts(s).

In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition consists substantially of plant substances(s) or their components(s), derivatives(s), or extracts(s).

[0115] Plant-based materials may be present in an amount of approximately 50 to 80% by weight of the aerosol-generating material.

[0116] In some embodiments, the plant material includes tobacco material. In some embodiments, the plant material is not tobacco material. In some embodiments, the aerosol-generating composition or article does not contain tobacco material.

[0117] As used herein, the term “tobacco material” refers to any material including tobacco or its derivatives or substitutes. Tobacco material may be any suitable form. The term “tobacco material” may include one or more of tobacco, tobacco derivatives, extended tobacco, reconstituted tobacco, paper reconstituted tobacco, or tobacco substitutes. Tobacco material may include one or more of crushed tobacco, tobacco fibers, cut tobacco, extruded tobacco, tobacco stems, tobacco leaves, reconstituted tobacco, and / or tobacco extracts.

[0118] In some embodiments, the strand contains tobacco. This offers the advantage that the strand delivers tobacco flavor to the user with improved sensory stimulation properties, but without using a combustion device. The tobacco-likeness is particularly improved because the extruded strand has a texture and flavor profile similar to tobacco. The plant material may be granular or granular material. In some embodiments, the plant material may be powder or ground. Alternatively or additionally, the plant material may include strips, strands, or fibers of plant material. For example, the plant material may include plant or plant material particles, granules, fibers, strips, and / or strands. In some embodiments, the plant material consists of plant material particles or granules. Plant material particles offer the advantage that the particle size distribution and resulting properties described herein can be more easily controlled.

[0119] In embodiments where the plant material is a particulate plant material, each particle of the particulate plant material may have a maximum dimension. As used herein, the term “maximum dimension” refers to the longest straight-line distance from the surface of a particle of the plant material or any point on the particle surface to any other surface point on the same particle of the plant material or on the particle surface. The maximum dimension of the particles of the particulate plant material may be measured using scanning electron microscopy (SEM).

[0120] In some embodiments, the maximum size of each particle of the plant material is approximately 800 μm. In some embodiments, the maximum size of each particle of the plant material is approximately 2000 μm, approximately 1000 μm, approximately 500 μm, approximately 350 μm, approximately 320 μm, or approximately 300 μm. In some embodiments, the maximum size of each particle of the plant material is approximately 200 μm to approximately 800 μm.

[0121] In some embodiments, the aggregate of plant material particles has a particle size distribution (D90) of at least about 50 μm, at least about 60, at least about 70 μm, at least about 80 μm, at least about 90, at least about 100 μm, at least about 110 μm, at least about 120 μm, and at least about 130 μm. In some embodiments, the aggregate of plant material particles has a particle size distribution (D90) of up to about 360, up to about 400 μm, up to about 500 μm, up to about 600 μm, up to about 700 μm, up to about 800 μm, or up to about 860 μm. In some embodiments, the aggregate of plant material particles has a particle size distribution (D90) of about 600 μm. In some embodiments, the aggregate of plant material particles has a particle size distribution (D90) of about 70 μm. In some embodiments, the collection of plant material particles has a particle size distribution (D90) of approximately 70 μm to approximately 600 μm, or approximately 70 to approximately 360 μm. The particle size distribution can be measured using a particle size and shape analyzer such as a camsizer, and the particle size distribution of the plant material particles can be determined using sieve analysis.

[0122] The inventors have found that the particle size of plant-based materials affects their tensile strength. A smaller particle size distribution is associated with higher tensile strength and higher density in aerosol-generating materials. Aerosol-generating compositions may be optimized for this purpose, and the particle size may be selected to provide appropriate tensile strength.

[0123] The inventors have found that the particle size distribution (D90) can be controlled to achieve a desired surface density of the aerosol-generating material. The surface density of the material is expressed in GSM (grams per square meter or g / m²). 2) can be measured. For example, a lower particle size distribution (D90) is associated with a higher areal density. When the aerosol - generating material is incorporated into an article for use in a non - combustible aerosol supply system, this higher areal density can reduce the fill value of the botanical material. A specific example of this is that a particle size distribution (D90) of 300 is predicted to result in an areal density of 246.6 g / m 2 of the areal density.

[0124] In some embodiments, the aerosol - generating material has an areal density of from about 100 g / m 2 to about 300 g / m 2 , from about 110 g / m 2 to about 280 g / m 2 , from about 120 g / m 2 to about 260 g / m 2 , from about 150 to about 210 g / m 2 , from about 180 to about 205 g / m 2 or from about 185 to about 195 g / m 2 . In some embodiments, the aerosol - generating material has an areal density of from about 180 to about 200 g / m 2 of the areal density.

[0125] The average volume density or basis weight of the aerosol - generating material can be calculated from the thickness of the aerosol - generating material and the areal density of the aerosol - generating material. In some embodiments, the average volume density or basis weight can be from about 0.5 g / cm 3 to about 1 g / cm 3 . In some embodiments, the average volume density is from about 0.6 g / cm 3 to about 0.9 g / cm 3 , from about 0.7 g / cm 3 to about 0.86 g / cm 3 . In some embodiments, the average volume density is about 0.8 g / cm 3 .

[0126] <> The aerosol - generating material has a low density compared to other aerosol - generating materials. As a result of this low density, the rod is lighter and thus easier to handle and store.

[0127] A lower density is desirable because it reduces the amount of material needed to produce the strand.

[0128] The mixture, aerosol-generating material, and / or aerosol-generating composition may further contain additional substances. In some embodiments, the mixture, aerosol-generating material, and / or aerosol-generating composition may contain an active substance.

[0129] The active substances used herein may be physiologically active materials intended to achieve or enhance physiological responses. Active substances may be selected from, for example, nutritional supplements, nootropics, and psychoactive substances. Active substances may be naturally occurring or obtained by synthesis. Examples of active substances include nicotine, caffeine, taurine, theine, vitamins such as B6, B12, or C, melatonin, cannabinoids, or their components, derivatives, or combinations. Active substances may also include one or more components, derivatives, or extracts of tobacco, cannabis, or other plant substances.

[0130] In one embodiment, the active substance is a legally permissible recreational drug.

[0131] In some embodiments, the active substance includes nicotine. In some embodiments, the active substance includes caffeine, melatonin, or vitamin B12.

[0132] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may contain flavorings.

[0133] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a flavor content of about 0 to about 20% by weight. In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a flavor content of about 0 to about 20% by weight, about 5 to about 20% by weight, about 5 to about 15% by weight, and about 8 to about 12% by weight.

[0134] In some embodiments, the flavoring is added to the first or second composition. This embodiment enjoys the advantages of adding the liquid flavoring to the liquid composition before mixing the first and second compositions, and of uniformly distributing the flavoring throughout at least the first composition. This embodiment has the disadvantage that the flavoring may be lost during the drying process.

[0135] In some embodiments, flavorings may be added after extrusion. For example, a flavoring nozzle may be provided in the machine to deposit the flavorings onto the surface of the strands of the aerosol-generating material.

[0136] As used herein, the terms “flavoring” and “flavoring agent” refer to materials that may be used to produce a desired taste, aroma, or other somatosensory effect in products intended for adult consumers, where permitted by local regulations.Flavors and flavorings are derived from naturally occurring flavoring materials, plant substances, extracts of plant substances, synthetically obtained materials, or combinations thereof (e.g., tobacco, cannabis, licorice, hydrangea, eugenol, magnolia leaf, chamomile, fenugreek, clove, maple, matcha, menthol, Japanese mint, anise, cinnamon, turmeric, Indian spices, Asian spices, herbs, wintergreen, cherry, berry, red berry, cranberry, peach, apple, orange, mango, clementine, lemon, etc.).

Flavors and flavorings may be in any suitable form, such as a liquid such as oil, a solid such as powder, or a gas.

[0137] In some embodiments, the flavor includes menthol, spearmint, and / or peppermint. In some embodiments, the flavor includes flavor components of cucumber, blueberry, citrus, and / or red berry. In some embodiments, the flavor includes eugenol. In some embodiments, the flavor includes flavor components extracted from tobacco. In some embodiments, the flavor includes flavor components extracted from cannabis.

[0138] In some embodiments, the flavor may include a sensory stimulant, which is usually chemically induced and intended to achieve somatosensory perception by stimulation of the fifth cranial nerve (trigeminal nerve) in addition to, or instead of, the aroma or taste nerves, and may include agents that produce a heating, cooling, tingling, or numbing effect. A suitable thermal agent may be, but is not limited to, vanillyl ethyl ether, and a suitable cooling agent may be, but is not limited to, eucalyptol (WS-3).

[0139] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may contain one or more functional materials. The one or more other functional materials may include one or more pH adjusters, colorants, preservatives, binders, fillers, stabilizers and / or antioxidants.

[0140] The binder is configured to bind components of the mixture, aerosol-generating material, and / or aerosol-generating composition. The mixture, aerosol-generating material, and / or aerosol-generating composition may contain two or more binders. In such embodiments, the binders may be the same or different.

[0141] In some embodiments, the binder includes or is a gelling agent. The binder may be selected from one or more compounds selected from the group including alginate, pectin, starch (and derivatives), cellulose (and derivatives), gum, silica or silicone compounds, clay, polyvinyl alcohol, and combinations thereof. For example, in some embodiments, the binder includes one or more of alginate, pectin, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose (CMC), pullulan, xanthan gum, guar gum, carrageenan, agarose, acacia gum, fumed silica, PDMS, sodium silicate, kaolin, and polyvinyl alcohol. In some cases, the binder includes alginate and / or pectin or carrageenan. In some embodiments, the binder includes CMC.

[0142] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a binder content of about 5 to about 40% by weight. In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a binder content of about 5 to about 30% by weight, about 5 to about 20% by weight, about 5 to about 15% by weight, or about 5 to about 10% by weight.

[0143] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may include an aerosol-forming agent. The aerosol-forming agent includes one or more components capable of forming an aerosol. The aerosol-forming agent includes one or more of the following: glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, mesoerythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixture, benzyl benzoate, benzyl phenylacetate, tributyline, lauryl acetate, lauric acid, myristic acid, and propylene carbonate. In some embodiments, the aerosol-forming agent is glycerin, glycerol, or propylene glycol.

[0144] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have an aerosol-forming agent content of about 5 to about 50% by weight. In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have an aerosol-forming agent content of about 10 to about 30% by weight, or about 15 to about 25% by weight.

[0145] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition includes a filler. The filler is generally a non-tobacco component, i.e., a component that does not contain tobacco-derived ingredients or components. The filler may include one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and a suitable inorganic adsorbent, such as molecular sieves. The filler may also be a non-tobacco fiber such as wood fiber or pulp or wheat fiber. The filler may be a cellulose-containing material or a cellulose derivative. The filler component may also be a non-tobacco cast material or a non-tobacco extruded material. In some embodiments, the filler is a cellulosic material, cellulose, or CMC. In some embodiments, the filler is essentially composed of cellulose or consists of cellulose.

[0146] In certain embodiments including a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood, wood pulp, hemp fiber, cellulose, or a cellulose derivative. While we do not wish to be bound by a single theory, it is believed that including a fibrous filler can increase the tensile strength of the resulting aerosol-generating material. The use of cellulose as a filler has been found to have a particularly favorable effect on the burst strength of the aerosol-generating material.

[0147] Fillers can also contribute to the texture of the aerosol-generating material. For example, fibrous fillers such as cellulose can result in an aerosol-generating material having relatively rough first and second surfaces. Conversely, non-fibrous granular fillers such as powdered chalk can result in an aerosol-generating material having relatively smooth first and second surfaces. In some embodiments, the aerosol-generating material includes a combination of different filler materials. Fillers can help improve the general structural properties of the aerosol-generating material, such as its tensile strength and burst strength.

[0148] In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a filler content of about 0 to about 20% by weight. In some embodiments, the mixture, aerosol-generating material and / or aerosol-generating composition may have a filler content of about 1 to about 15% by weight, about 3 to about 10% by weight, or about 4 to about 6% by weight.

[0149] In some embodiments of the present invention, an article for use with a non-combustible aerosol supply system comprises an aerosol-generating composition.

[0150] Articles or consumables are articles containing or consisting of aerosol-generating materials, some or all of which are intended to be consumed during use by the user. Articles may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol-generating area, a housing, packaging material, a mouthpiece, a filter, and / or an aerosol modifier. Articles may also comprise an aerosol generator, such as a heater, which generates heat during use to cause the aerosol-generating material to produce an aerosol. The heater may comprise, for example, a flammable material, an electrically conductive material, or a susceptor.

[0151] In some embodiments, the aerosol-generating composition comprises different aerosol-generating materials, and the aerosol-generating composition comprises different or varying amounts of flavorings, plant materials, binders, water, and / or fillers. Preferably, stands containing different aerosol-generating materials may be mixed together in the aerosol-generating composition. The mixing ratio can be easily controlled by varying the number of strands or by changing the size / shape of the strands. This means that the flavor of the resulting aerosol can be fine-tuned and controlled. In addition, this improved consistency is beneficial to manufacturing because the strands are reproducible.

[0152] In an exemplary embodiment, Figure 4 is a perspective view of Article 1 for use in an aerosol delivery system. Figure 5 is a side cross-sectional view of Article 1.

[0153] Article 1 comprises a mouthpiece 2 and an aerosol generating section 3 connected to the mouthpiece 2. In this example, the aerosol generating section 3 comprises an aerosol generating composition comprising a plurality of strands. Article 1 comprises a downstream end 2b and an upstream end 2a located away from the downstream end 2b.

[0154] In this example, the aerosol-generating material is enclosed by packaging material 5. In this example, packaging material 5 is a non-permeable packaging material. In some embodiments, the packaging material is paper, but it may be made of an alternative material such as aluminum.

[0155] The mouthpiece 2 includes a cooling section 6, also called a cooling element, positioned adjacent to the source of the aerosol-generating composition 3 immediately downstream. In this example, the cooling section 6 is in contact with the source of the aerosol-generating material. The mouthpiece 2 also, in this example, includes at the mouthpiece end of article 1 a body 7 of the material downstream of the cooling section 6 and a hollow tubular element 8 downstream of the body 7 of the material.

[0156] In some embodiments, one or more extruded strands are aligned with the longitudinal axis of the article. One or more extruded strands may be aligned within the aerosol-generating section such that their longitudinal dimensions are aligned parallel to the longitudinal axis X-X' of article 1. Alternatively, strands may generally be arranged so that the longitudinal dimensions of aligned strands cross the longitudinal axis of the article. In some embodiments, at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95% of the strands may be arranged so that at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 95% of the strands have longitudinal dimensions aligned parallel to the longitudinal axis of the article. The majority of the strands may be arranged so that the longitudinal dimensions of the majority of the strands are aligned parallel to the longitudinal axis of the article. In some embodiments, approximately 95% to 100% of the strands are arranged such that the longitudinal dimension of approximately 95% to 100% of the strands is aligned parallel to the longitudinal axis of the article.

[0157] In some embodiments, substantially all of the strands are positioned within the aerosol-generating section such that substantially all of the longitudinal dimensions of the strands are aligned parallel to the longitudinal axis of the aerosol-generating section of the article.

[0158] This allows the strands to be aligned and packed together, enabling more strands to be packed into the item. This is preferable because it provides a stronger flavor to the user in a smaller amount of space or size in the item.

[0159] The orientation of the strands can also influence the pressure drop across the article, resulting in less resistance to the airflow through the article.

[0160] In some embodiments, the extruded strands are not aligned. For example, the strands may not be linear, but non-linear, wavy, or have an irregular orientation. This increases the space occupied by the strands, reducing the volume within the article and the weight of the article. This can also increase airflow and provide a more appropriate pressure drop.

[0161] In some embodiments, the pressure drop across the article is about 20 to about 120 mmWg, about 30 to about 80 mmWg, or about 30 to about 60 mmWg. The pressure drop can be measured between the upstream and downstream ends of the article. In some embodiments, a non-combustible aerosol supply system comprising the article is provided. The non-combustible aerosol supply system may be as described herein.

[0162] As used herein, the term “air permeability” refers to the time required for a known amount of air, aerosol, or a mixture of air and aerosol to pass through a known volume of an aerosol-generating material. Therefore, lower air permeability is associated with lower permeability of the aerosol-generating material. In some embodiments, the air permeability of the aerosol-generating material is approximately 5 to approximately 40 s / 100 cm. 3 , about 5~20s / 100cm 3 , or approximately 5-15 seconds / 100cm 3 The air permeability may be measured using a Gurley Precision Instruments densometer and / or a Gurley Precision Instruments porosity test plate.

[0163] Aerosol-generating materials benefit from lower air permeability. Lower air permeability positively impacts aerosol generation because more air or aerosols pass through the material in a given time. This allows for the generation and delivery of more aerosols to the user.
