Description

[0001] This invention relates to an aerosol generating article comprising an aerosol generating matrix strip for generating inhalable aerosols upon heating. The invention also relates to an aerosol generating system comprising an aerosol generating article and an aerosol generating apparatus configured to heat the aerosol generating article. Furthermore, the invention relates to a container comprising a plurality of aerosol generating articles.

[0002] Aerosol-generating articles in which an aerosol-generating matrix containing aerosol-generating materials (such as tobacco-containing materials) is heated rather than burned are known in the art. The purpose of such "heated" aerosol-generating articles is to reduce certain types of smoke components produced by the combustion and thermal degradation of tobacco in conventional cigarettes.

[0003] Typically, in heated aerosol-generating articles, aerosols are generated by transferring heat from a heat source to a physically separated aerosol-generating matrix. During use, volatile compounds are released from the aerosol-generating matrix via heat transfer from the heat source to the aerosol-generating matrix and are entrained in the air drawn through the aerosol-generating article. As the released compounds cool, they condense to form an aerosol inhaled by the user.

[0004] Many handheld aerosol generating devices configured as aerosol generating substrates for heated aerosol generating articles are known in the art. These devices include electrically operated aerosol generating devices in which aerosols are generated by transferring heat from one or more electrically heated elements of the aerosol generating device to the aerosol generating substrate of the heated aerosol generating article. Known handheld electrically operated aerosol generating devices typically include a battery, control electronics, and one or more electrically heated elements for heating the aerosol generating substrate of a heated aerosol generating article specifically designed for use with an aerosol generating device.

[0005] Some known electrically operated aerosol generating devices include one or more external heating elements. For example, WO2020 / 115151 A1 discloses an aerosol generating system comprising an aerosol generating article and an electrically operated aerosol generating device, the electrically operated aerosol generating device including an external heating element defining an outer periphery of the aerosol generating article. Other known electrically operated aerosol generating devices include an internal heating element configured to be inserted into the aerosol generating matrix of a heated aerosol generating article. Electrically operated aerosol generating devices including sensors configured to inductively heat the aerosol generating matrix of a heated aerosol generating article are also known.

[0006] Heated aerosol generating articles designed for use with aerosol generating apparatus typically include multiple components in addition to the aerosol generating matrix. For example, aerosol generating articles including a mouthpiece element located downstream of the aerosol generating matrix are known. The mouthpiece element is typically configured to filter the aerosol generated by the aerosol generating matrix and to provide suitable suction resistance for the aerosol generating article. Aerosol generating articles including an aerosol cooling element located downstream of the aerosol generating matrix are also known. Hollow tubular elements can act as aerosol cooling elements to facilitate cooling of the aerosol generated by the aerosol generating matrix. Aerosol generating articles including an upstream element located upstream of the aerosol generating matrix are also known. The upstream element can be configured to reduce or prevent the migration of aerosol generating matrix material from the aerosol generating matrix.

[0007] Variations in each component of an aerosol-generating article can affect the quality and consistency of the aerosol generated and delivered to the user. For example, manufacturing defects in the mouthpiece element, hollow tubular element, or any other component of an aerosol-generating article can affect, for instance, the draw resistance of the aerosol-generating article, the temperature of the aerosol delivered to the user, and the composition of the aerosol delivered to the user. In aerosol-generating articles comprising multiple components, inconsistencies in the user experience between one aerosol-generating article and another can be significant.

[0008] Manufacturing each component of an aerosol-generated article and assembling multiple components to form the aerosol-generated article can present manufacturing challenges.

[0009] Including multiple components in aerosol-generating articles for various purposes can increase the size and weight of the articles. This can create problems associated with the storage and transportation of the aerosol-generating articles, as well as their packaging or containers.

[0010] Aerosol-generating products are typically disposed of after use. Disposal of aerosol-generating products, which often include multiple components, can be complex and wasteful. This is especially true when some components of the aerosol-generating product are non-biodegradable or non-recyclable.

[0011] It is desired to provide a novel and improved aerosol-generating article that delivers the desired sensory experience to the user and exhibits improved performance consistency between different aerosol-generating articles. It is also desired to provide a cost-effective aerosol-generating article that is simple to manufacture and can be efficiently stored and transported. Furthermore, it is desired to provide an aerosol-generating article that reduces waste and has a better environmental impact compared to known aerosol-generating articles.

[0021] According to a third aspect of the invention, a container is provided comprising a plurality of aerosol-generating articles, wherein each of the plurality of aerosol-generating articles comprises an aerosol-generating matrix strip containing nicotine and having a total aerosol forming agent content of at least about 10% by weight on a dry weight basis, wherein each of the plurality of aerosol-generating articles has a length of less than or equal to about 40 millimeters, and wherein each of the plurality of aerosol-generating articles has a ratio of at least about 0.75 of the length of the aerosol-generating matrix strip to the length of the aerosol-generating article.

[0023] As used herein with reference to the present invention, the term "aerosol generating article" is used to describe articles comprising an aerosol generating matrix that is heated to generate an inhalable aerosol for delivery to a user.

[0024] As used herein with reference to this invention, the term "aerosol generating matrix" is used to describe a matrix containing an aerosol generating material that, when heated, releases volatile compounds that can generate aerosols.

[0025] As used herein with reference to this invention, the term "aerosol" is used to describe a dispersion of solid particles or droplets, or a combination of solid particles and droplets, in a gas. Aerosols can be visible or invisible. Aerosols can include vapors of substances that are typically liquid or solid at room temperature, as well as solid particles or droplets, or a combination of solid particles and droplets.

[0026] As used herein with reference to this invention, the term "aerosol generating apparatus" is used to describe an apparatus that interacts with an aerosol generating matrix of an aerosol generating article to generate an aerosol.

[0027] The aerosol generating article according to the invention has a proximal end through which, in use, the aerosol exits the aerosol generating article for delivery to the user. The proximal end of the aerosol generating article may also be referred to as the downstream end or the orifice of the aerosol generating article. In use, the user draws air directly or indirectly onto the proximal end of the aerosol generating article to inhale the aerosol generated by the aerosol generating article.

[0028] The aerosol-generating article according to the present invention has a distal end. The distal end is opposite to the proximal end. The distal end of the aerosol-generating article may also be referred to as the upstream end of the aerosol-generating article.

[0029] The components of the aerosol generating article according to the invention can be described as being upstream or downstream of each other based on their relative positions between the proximal end and the distal end of the aerosol generating article.

[0030] As used herein with reference to the present invention, the term "longitudinal" is used to describe the direction between the proximal and distal ends of an aerosol-generating article.

[0031] As used herein with reference to the present invention, the term "length" is used to describe the maximum dimension in the longitudinal direction of an aerosol generating article or a component of an aerosol generating article or a component of an aerosol generating apparatus.

[0032] As used herein with reference to this invention, the term "transverse" is used to describe a direction perpendicular to the longitudinal direction. Unless otherwise stated, the term "section" in reference to an aerosol generating article or a component of an aerosol generating article or an aerosol generating apparatus or a component of an aerosol generating apparatus means a cross-section.

[0033] As used herein with reference to this invention, the term "width" refers to the maximum dimension in the transverse direction of an aerosol generating article or a component of an aerosol generating article, or an aerosol generating apparatus or a component of an aerosol generating apparatus. When the aerosol generating article has a substantially circular cross-section, the width of the aerosol generating article corresponds to the diameter of the aerosol generating article.

[0034] As used herein with reference to this invention, the term "total aerosol forming agent content" is used to describe the combined content of all aerosol forming agents in the aerosol generating matrix.

[0035] The inventors of this invention have discovered that the functions of some components of prior art aerosol-generating articles can be provided by an aerosol-generating apparatus. For example, the inventors of this invention have discovered that it is possible to provide an aerosol-generating apparatus with the function of properly cooling and filtering aerosols generated from an aerosol-generating matrix, and that the aerosol-generating apparatus provides a significant amount of suction resistance (RTD) for the aerosol-generating system.

[0036] This allows for the simplification of aerosol-generated articles and avoids the need for some components in existing aerosol-generated articles, such as non-biodegradable or non-recyclable components. This simplifies the manufacture of aerosol-generated articles and minimizes waste.

[0037] An aerosol generating article having a length of about 40 mm or less and including an aerosol generating matrix strip whose length is at least about 75% of the length of the aerosol generating article means that the aerosol generating matrix strip forms at least a majority of the aerosol generating article. This can reduce or avoid the impact of any changes to any additional components of the aerosol generating article (if present) on the aerosol delivered to the user. This can improve the consistency of the aerosol delivered to the user between one aerosol generating article and another.

[0038] An aerosol generating article having a length of about 40 mm or less and including an aerosol generating matrix strip that is at least about 75% the length of the aerosol generating article means that a large portion of the aerosol generating article can be used to generate aerosols. This improves the efficiency of the aerosol generating article.

[0039] Aerosol-generating articles having a length of about 40 mm or less and including an aerosol-generating matrix strip that is at least about 75% the length of the aerosol-generating article can be relatively compact. Compared to known aerosol-generating articles, this can improve the efficiency of the storage and transportation of the aerosol-generating article and its packaging or container.

[0040] The ratio of the length of the aerosol generating matrix strip to the length of the aerosol generating article can be at least about 0.5, at least about 0.6, at least about 0.65, at least about 0.7, at least about 0.75, at least about 0.8, at least about 0.85, or at least about 0.9. Increasing the ratio of the length of the aerosol generating matrix strip to the length of the aerosol generating article can further improve the consistency of the aerosol delivered to the user and the efficiency of the aerosol generating article.

[0041] The aerosol generating matrix strip can extend the entire length of the aerosol generating article. The ratio of the length of the aerosol generating matrix strip to the length of the aerosol generating article can be less than or equal to approximately 0.95.

[0042] Aerosol-generated articles may have a length of about 55 mm, about 50 mm, about 45 mm, about 40 mm, about 35 mm, about 30 mm, or about 25 mm.

[0043] Aerosol-generated articles may have a length of at least about 8 mm, at least about 10 mm, or at least about 12 mm.

[0044] The length of an aerosol-generated article can be selected based on the desired balance between the efficiency of its storage and transportation and the amount of aerosol-generating material in the article, in order to provide the desired aerosol delivery experience.

[0045] The aerosol-generating article may have a length between about 8 mm and about 55 mm, between about 8 mm and about 50 mm, between about 8 mm and about 45 mm, between about 8 mm and about 40 mm, between about 8 mm and about 35 mm, between about 8 mm and about 30 mm, or between about 8 mm and about 25 mm.

[0046] The aerosol-generating article may have a length between about 10 mm and about 55 mm, between about 10 mm and about 50 mm, between about 10 mm and about 45 mm, between about 10 mm and about 40 mm, between about 10 mm and about 35 mm, between about 10 mm and about 30 mm, or between about 10 mm and about 25 mm.

[0047] The aerosol-generated article may have a length between about 12 mm and about 55 mm, between about 12 mm and about 50 mm, between about 12 mm and about 45 mm, between about 12 mm and about 40 mm, between about 12 mm and about 35 mm, between about 12 mm and about 30 mm, or between about 12 mm and about 25 mm.

[0048] Preferably, the aerosol-generating article is substantially prismatic in shape. The aerosol-generating article may have a substantially constant cross-sectional shape along its entire length.

[0049] Preferably, the aerosol-generating article has a substantially circular cross-section. The aerosol-generating article may also be substantially cylindrical.

[0050] Aerosol-generating articles may have a diameter of at least about 5 mm, at least about 6 mm, or at least about 7 mm. Aerosol-generating articles may also have a diameter of less than or equal to about 12 mm, less than or equal to about 10 mm, or less than or equal to about 8 mm. For example, aerosol-generating articles may have a diameter between about 5 mm and about 8 mm.

[0051] Preferably, the aerosol-generated article has a substantially constant diameter along its entire length.

[0052] The ratio of the length to the diameter of the aerosol-generated article can be less than or equal to about 6, less than or equal to about 5, or less than or equal to about 4. Reducing the ratio of the length to the diameter of the aerosol-generated article can produce a more compact aerosol-generated article, which may be advantageous for the storage and transportation of the aerosol-generated article.

[0053] The ratio of the length of the aerosol-generated article to its diameter may be at least about 1 or at least about 1.5.

[0054] The ratio of the length of the aerosol-generated article to the diameter of the aerosol-generated article can be between about 1 and about 6, between about 1 and about 5, or between about 1 and about 4.

[0055] The ratio of the length of the aerosol-generating article to the diameter of the aerosol-generating article can be between about 1.5 and about 6, between about 1.5 and about 5, or between about 1.5 and about 4.

[0056] Aerosol-generating articles can have a substantially rectangular cross-section. Aerosol-generating articles can also be substantially cuboid.

[0057] Aerosol-generated products can be planar aerosol-generated products.

[0058] Aerosol-generated articles may have an overall RTD of less than or equal to about 40 mm H2O, less than or equal to about 35 mm H2O, less than or equal to about 30 mm H2O, or less than or equal to about 20 mm H2O.

[0059] Reducing the RTD of aerosol-generated articles can minimize the impact of any variation in the RTD between one aerosol-generated article and another. This can improve the consistency of the performance of aerosol-generated articles.

[0060] Reducing the RTD of aerosol-generated articles can reduce any filtration of the aerosols passing through the aerosol-generated articles. This can improve the aerosol delivery of aerosol-generated articles.

[0061] Aerosol-generated articles may have an overall RTD of at least about 10 mm H2O.

[0062] The aerosol generation matrix strip can provide most of the RTD of the aerosol generation article. For example, the ratio of the RTD of the aerosol generation matrix strip to the total RTD of the aerosol generation article can be at least about 0.8, at least about 0.85, or at least about 0.9.

[0063] The ratio of the RTD of the aerosol generation matrix strip to the total RTD of the aerosol generation article can be less than or equal to about 1. The aerosol generation matrix strip can provide essentially all the RTD of the aerosol generation article.

[0064] Unless otherwise stated, the suction resistance (RTD) of an aerosol-generating article or a component thereof is measured at a volumetric flow rate of about 17.5 mL / s at the proximal or downstream end of the aerosol-generating article or a component thereof, in accordance with ISO 6565-2015 at a temperature of about 22 degrees Celsius, a pressure of about 101 kPa (about 760 Torr) and a relative humidity of about 60%.

[0065] In the case where an aerosol generating article includes an aerosol generating matrix strip and one or more additional elements, the contribution of the one or more additional elements to the overall RTD of the aerosol generating article can be minimal or negligible. As discussed above, the inventors of the present invention have found it possible to provide an aerosol generating apparatus that provides a significant amount of RTD for the aerosol generating system. Therefore, it may not be necessary to include elements in the aerosol generating article to increase the overall RTD of the aerosol generating article.

[0066] The aerosol generating matrix strip may have a length of at least about 8 mm, at least about 10 mm, or at least about 12 mm.

[0067] The aerosol generating matrix strip may have a length of about 30 mm, about 25 mm, or about 20 mm.

[0068] The aerosol generating matrix strip may have a length between about 8 mm and about 30 mm, between about 8 mm and about 25 mm, or between about 8 mm and about 20 mm.

[0069] The aerosol generating matrix strip may have a length between about 10 mm and about 30 mm, between about 10 mm and about 25 mm, or between about 10 mm and about 20 mm.

[0070] The aerosol generating matrix strip may have a length between about 12 mm and about 30 mm, between about 12 mm and about 25 mm, or between about 12 mm and about 20 mm.

[0074] Preferably, the aerosol generating matrix strip has a substantially constant diameter along its entire length.

[0075] Aerosol-generating matrix strips may have a substantially rectangular cross-section. Aerosol-generating article strips may be substantially cuboid.

[0076] Aerosol generation matrix strips can be planar strips of aerosol generation matrix.

[0077] The aerosol generating matrix strip may have a base defined by a length extending in the x-direction, a width extending in the y-direction, and a height extending in the z-direction. The airflow path may be defined in the x / y plane as extending from one side of the aerosol generating matrix strip through it to the other side.

[0078] The aerosol generating matrix strip may include a substantially planar upper surface defined by a length extending in the x-direction and a width extending in the y-direction, and a substantially planar lower surface defined by a length extending in the x-direction and a width extending in the y-direction. The substantially planar upper surface and the substantially planar lower surface may be vertically spaced apart from each other by a height defined in the z-direction.

[0079] The aerosol generating matrix may have one or both of its length (x dimension) and width (y dimension) equal to or greater than twice the value of its height (z dimension), for example, three, four or five times the height, and optionally equal to or greater than six times the height, for example, ten, fifteen or twenty times the height.

[0080] The aerosol generating matrix strip may include a first planar layer and a corrugated layer disposed on the surface of the first planar layer, wherein at least one of the first planar layer and the corrugated layer comprises or is composed of an aerosol generating material.

[0081] The planar strip of the aerosol generating matrix may include a first planar layer, a second planar layer, and a corrugated layer disposed between the first planar layer and the second planar layer, wherein at least one of the first planar layer, the second planar layer, and the corrugated layer contains or is composed of an aerosol generating material.

[0082] The ratio of the weight of the aerosol-generating matrix strip to the total weight of the aerosol-generating article can be at least about 0.75, at least about 0.8, at least about 0.85, or at least about 0.9. Increasing the ratio of the weight of the aerosol-generating matrix strip to the total weight of the aerosol-generating article can increase the usable weight of the aerosol-generating article capable of generating aerosols. This can improve the efficiency of the article and reduce any burdens associated with the storage and transportation of the aerosol-generating article.

[0083] The aerosol generating matrix strip may have a weight of at least about 90 mg, at least about 100 mg, at least about 120 mg, or at least about 150 mg.

[0084] The aerosol generating matrix strip may have a weight of less than or equal to 320 mg, less than or equal to about 280 mg, less than or equal to about 240 mg, or less than or equal to about 200 mg.

[0085] The aerosol generating matrix strip may have a weight between about 90 mg and about 320 mg, between about 90 mg and about 280 mg, between about 90 mg and about 240 mg, or between about 90 mg and about 200 mg.

[0086] The aerosol generating matrix strip may have a weight between about 100 mg and about 320 mg, between about 100 mg and about 280 mg, between about 100 mg and about 240 mg, or between about 100 mg and about 200 mg.

[0087] The aerosol generating matrix strip may have a weight between about 120 mg and about 320 mg, between about 120 mg and about 280 mg, between about 120 mg and about 240 mg, or between about 120 mg and about 200 mg.

[0089] The aerosol generating matrix strip may have a density of at least about 150 mg / cm³, at least about 175 mg / cm³, at least about 200 mg / cm³, or at least about 250 mg / cm³.

[0090] Increasing the density of the aerosol generation matrix strip increases its weight. Increasing the weight of the aerosol generation matrix strip increases the ratio of its weight to the total weight of the aerosol-generated product.

[0091] The aerosol generating matrix strip may have a density of less than or equal to about 500 mg / cm³, less than or equal to about 450 mg / cm³, less than or equal to about 400 mg / cm³, or less than or equal to about 350 mg / cm³.

[0092] The density of the aerosol generating matrix strip can be selected such that when the aerosol generating article is inserted into and removed from the aerosol generating device, the aerosol generating matrix strip remains within the scope of the packaging that defines the aerosol generating matrix strip.

[0093] The aerosol generating matrix strip may have a density between about 150 mg / cm³ and about 500 mg / cm³, between about 150 mg / cm³ and about 450 mg / cm³, between about 150 mg / cm³ and about 400 mg / cm³, or between about 150 mg / cm³ and about 350 mg / cm³.

The bulk density of an aerosol generating matrix strip can be calculated by measuring the total weight of the strip and dividing it by the volume of the strip (excluding any packaging).

[0126] When the aerosol generating matrix strip comprises multiple aerosol generating matrix segments, the glycerol content of the aerosol generating matrix strip discussed above can also be applied to each aerosol generating matrix segment.

[0127] The aerosol generating matrix strip may contain tobacco material, such as homogenized tobacco material. As used herein with reference to this invention, the term "homogenized tobacco material" is used to describe a material formed by agglomerating particulate tobacco material. The aerosol generating matrix strip may include one or more aerosol generating matrix segments, each segment containing tobacco material. For example, the aerosol generating matrix strip may include multiple aerosol generating matrix segments, each aerosol generating matrix segment containing tobacco material.

[0133] The tobacco material strips may have a width between about 0.5 mm and about 2 mm, between about 0.5 mm and about 1.2 mm, or between about 0.5 mm and about 0.9 mm.

[0134] The tobacco material strips may have a width between about 0.6 mm and about 2 mm, between about 0.6 mm and about 1.2 mm, or between about 0.6 mm and about 0.9 mm.

[0137] The tobacco material strips can have a length between approximately 10 mm and approximately 40 mm.

[0138] At least about 20% by weight of a plurality of tobacco material strips, based on dry weight, may extend along the entire length of the aerosol-generating matrix strip.

These multiple tobacco material strips, comprising less than or equal to about 60% by weight on a dry weight basis, may have a length substantially the same as the length of the aerosol-generating matrix strip.

[0140] Multiple tobacco material strips, ranging from approximately 20% to 60% by dry weight, may extend along the entire length of the aerosol-generating matrix strip. These multiple tobacco material strips, ranging from approximately 20% to 60% by dry weight, may have a length substantially the same as the length of the aerosol-generating matrix strip.

[0141] The size of the aerosol-generating material (such as multiple tobacco material strips) in the aerosol-generating matrix strip can affect the heat distribution within the aerosol-generating matrix strip. Furthermore, the size of the aerosol-generating material can affect the suction resistance of the product.

[0142] The aerosol-generating matrix strip may include multiple pellets or particles of tobacco material. The aerosol-generating matrix strip may include multiple pellets or particles of homogenized tobacco material.

[0143] At least about 60% by weight of the plurality of pellets or particles may have a maximum size greater than about 1 mm, at least about 70% by weight of the plurality of pellets or particles may have a maximum size greater than about 1 mm, or at least about 80% by weight of the plurality of pellets or particles may have a maximum size greater than about 1 mm.

[0144] When the homogenized tobacco material is in the form of multiple pellets or particles, at least about 70% by weight of the multiple pellets or particles may have a maximum size greater than about 0.5 mm, at least about 80% by weight of the multiple pellets or particles may have a maximum size greater than about 0.5 mm, or at least about 90% by weight of the multiple pellets or particles may have a maximum size greater than about 0.5 mm.

[0145] For example, at least about 80% by weight of the plurality of pellets or particles may have a maximum size greater than about 1 mm and at least about 90% by weight of the plurality of pellets or particles may have a maximum size greater than about 0.5 mm.

[0146] The aerosol-generating matrix strip may include one or more tobacco material sheets.

[0147] The aerosol-generating matrix strip may include one or more homogenized tobacco material sheets.

[0148] One or more tobacco material sheets may each individually have a thickness of at least about 100 micrometers, at least about 150 micrometers, or at least about 300 micrometers.

[0149] As used herein with reference to this invention, individual thickness refers to the thickness of a single tobacco material sheet, while combined thickness refers to the total thickness of all tobacco material sheets constituting an aerosol generating matrix strip or aerosol generating matrix segment. For example, if an aerosol generating matrix strip is formed from two individual tobacco material sheets, the combined thickness is the sum of the thicknesses of the two individual tobacco material sheets, or, in the case where two tobacco material sheets are stacked within an aerosol generating matrix strip, the measured thickness of the two tobacco material sheets.

[0150] One or more tobacco material sheets may each individually have a thickness of less than or equal to about 600 micrometers, less than or equal to about 300 micrometers, or less than or equal to about 250 micrometers.

[0151] One or more tobacco material sheets may each individually have a thickness between about 100 micrometers and about 600 micrometers, between about 100 micrometers and about 300 micrometers, or between about 100 micrometers and about 250 micrometers.

[0152] One or more tobacco material sheets may each individually have a thickness between about 150 micrometers and about 600 micrometers, between about 150 micrometers and about 300 micrometers, or between about 150 micrometers and about 250 micrometers.

[0153] One or more tobacco material sheets may each individually have a thickness between about 250 micrometers and about 600 micrometers, between about 250 micrometers and about 300 micrometers, or between about 250 micrometers and about 250 micrometers.

[0154] One or more tobacco material sheets may each have a length substantially the same as the length of the aerosol-generating matrix.

[0155] One or more tobacco material sheets may have been rolled, folded, gathered, and pleated in one or more of the following ways:

[0156] The curling, folding, agglomeration, or pleating of one or more tobacco material sheets can cause the separation of one or more tobacco material sheets to form tobacco material strips. For example, one or more tobacco material sheets may be curled to such an extent that the integrity of one or more tobacco material sheets is disrupted at multiple parallel ridges or corrugations, thereby causing the separation of the material and resulting in the formation of tobacco material strips.

[0157] The aerosol-generating matrix strip contains nicotine. As used herein with reference to this invention, the term "nicotine" is used to describe nicotine, nicotine base, or nicotine salt.

[0158] The aerosol-generating matrix strip may contain non-tobacco plant materials, such as homogenized non-tobacco plant materials. Non-tobacco plant materials may include particles selected from rosemary particles, star anise particles, ginger particles, clove particles, eucalyptus particles, or combinations thereof.

[0159] As used herein with reference to this invention, the term "homogenized plant material" encompasses any plant material formed by the aggregation of plant particles. For example, homogenized plant material sheets or webs can be formed by agglomerating plant material particles obtained by grinding, milling, or pulverizing non-tobacco plant material and optionally tobacco leaves and tobacco stems. Homogenized plant materials can be produced by casting, extrusion, papermaking processes, or any other suitable process known in the art.

[0160] As used herein with reference to this invention, the term "plant particles" or "particles of a plant" encompasses particles derived from any suitable plant material that are capable of generating one or more volatile flavor compounds upon heating. This term should be considered to exclude particles of inert plant materials (such as cellulose) that do not contribute to the sensory output of the aerosol-generating matrix. Depending on the plant from which the plant particles originate, plant particles may be produced by grinding or pulverizing leaves, fruits, stems, stalks, roots, seeds, buds, or bark, or any other suitable part of the plant.

[0161] The aerosol-generating matrix strips can be formed from homogenized plant material. The homogenized plant material may include one or both of tobacco plant particles and non-tobacco plant particles.

[0162] Homogenized plant material may include non-tobacco plant particles or tobacco particles in a dry weight range of about 1% to about 65% of the dry weight.

[0163] Homogenized plant materials may include aerosol forming agents at a dry weight of between 15% and 55% of the dry weight.

[0164] Homogenized plant materials may include cellulose ethers in the range of 2% to 10% by weight on a dry weight basis.

[0165] The homogenized plant material may include additional cellulose at a dry weight of between 5% and 50% (w / w). The additional cellulose may not be derived from non-tobacco plant particles. The ratio of additional cellulose to cellulose ether may be at least 2.

[0166] By using a combination of cellulose ethers and additional cellulose in homogenized plant materials, more efficient bonding of plant particles can be achieved, resulting in homogenized plant materials with significantly higher tensile strength. Therefore, the resulting homogenized plant materials can be readily processed using existing high-speed equipment and techniques to form aerosol-generating matrices. For certain non-tobacco plant materials, this can thus produce acceptable homogenized plant materials with higher levels of non-tobacco plant particles than previously possible.

[0167] Aerosol generating matrix strips may include solid aerosol generating matrix strips. As used herein with reference to this invention, the term "solid" is used to describe an aerosol generating matrix having a stable size and shape and not flowing at 23°C.

[0168] The solid aerosol generating matrix may contain one or more cellulose-based reagents. The solid aerosol generating matrix may have a total cellulose-based reagent content of greater than or equal to about 35% by weight based on the dry weight of the solid aerosol generating matrix.

[0169] The solid aerosol generating matrix may contain one or more cellulose-based film-forming agents. As used herein with reference to the present invention, the term "cellulose-based film-forming agent" is used to describe cellulose polymers capable of forming continuous films alone or in the presence of an auxiliary thickener.

[0170] The cellulose-based film-forming agent may be selected from carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxyethyl methyl cellulose (HEMC), hydroxypropyl cellulose (HPC), hydroxypropyl methyl cellulose (HPMC), and methyl cellulose (MC). Preferably, the solid aerosol generating matrix comprises one or both of carboxymethyl cellulose (CMC) and hydroxypropyl methyl cellulose (HPMC).

[0171] The matrix for generating solid aerosols may contain one or more carboxylic acids.

[0172] The one or more carboxylic acids may be free of any non-carboxyalkyl hydroxyl groups. The one or more carboxylic acids may be free of any ketone groups. The inclusion of one or more carboxylic acids free of any non-carboxyalkyl hydroxyl groups and ketone groups in the solid aerosol generating matrix advantageously improves the stability of the solid aerosol generating matrix and nicotine in the solid aerosol generating matrix during the storage of the aerosol generating article. The inclusion of one or more carboxylic acids free of any non-carboxyalkyl hydroxyl groups and ketone groups in the solid aerosol generating matrix advantageously inhibits corrosion of the aerosol generating article and components (such as some metal components) of the aerosol generating system including the aerosol generating article. For example, in the case where the aerosol generating article includes a receptor, the inclusion of such one or more carboxylic acids advantageously inhibits corrosion of the receptor.

[0173] The one or more carboxylic acids may have a pKa of less than or equal to 3.5 in water at 25°C. Containing one or more carboxylic acids with such a pKa in the solid aerosol generating matrix advantageously improves the stability of the solid aerosol generating matrix and nicotine within it during the storage of the aerosol-generating article. Containing one or more carboxylic acids with such a pKa in the solid aerosol generating matrix advantageously inhibits corrosion of the aerosol-generating article and components (such as some metal parts) of the aerosol-generating system including the aerosol-generating article.

[0174] The one or more carboxylic acids may be selected from: acetic acid, adipic acid, benzoic acid, citric acid, fumaric acid, maleic acid, malic acid, myristic acid, oxalic acid, salicylic acid, stearic acid, succinic acid, and undecanoic acid. The one or more carboxylic acids may be selected from: acetic acid, benzoic acid, citric acid, fumaric acid, maleic acid, and malic acid. The one or more carboxylic acids may be selected from: fumaric acid, maleic acid, and malic acid. Preferably, the solid aerosol generating matrix comprises one or both of fumaric acid and maleic acid.

[0175] The solid aerosol generating matrix may have a total carboxylic acid content of greater than or equal to 0.5% by weight.

[0176] The solid aerosol generation matrix can remain solid when heated to a temperature between 180°C and 350°C.

[0177] The solid aerosol generating matrix may not contain ι-carrageenan or κ-carrageenan.

[0178] The solid aerosol generation matrix can be a solid aerosol generation membrane.

[0179] As used herein with reference to this invention, the term "membrane" is used to describe a solid aerosol-generating matrix whose thickness is significantly less than its width or length.

[0180] As used herein with reference to the present invention, the term "thickness" in relation to solid aerosol-generated films is used to describe the minimum dimension between relatively substantially parallel surfaces of a solid aerosol-generated film.

[0181] The solid aerosol generating membrane may have a thickness of at least about 0.05 mm, at least about 0.1 mm, at least about 0.2 mm, or at least about 0.3 mm. The solid aerosol generating membrane may also have a thickness of less than or equal to about 1.2 mm, less than or equal to about 1 mm, less than or equal to about 0.8 mm, less than or equal to about 0.6 mm, or less than or equal to about 0.4 mm.

[0182] Solid aerosol generating membranes may have a basis weight of at least about 85 g / m², at least about 100 g / m², at least about 120 g / m², or at least about 140 g / m². Solid aerosol generating membranes may have a basis weight of less than or equal to about 300 g / m², less than or equal to about 280 g / m², or less than or equal to about 260 g / m².

[0183] Solid aerosol generating films can be formed by any suitable method. For example, solid aerosol generating films can be formed by batch casting, continuous casting, or extrusion.

[0184] Solid aerosol generating membranes can be self-supporting. In other words, the properties of solid aerosol generating membranes allow them to separate from the supporting surface even when formed by casting slurry onto it.

[0185] Solid aerosol generating membranes (SAMs) can be disposed on a support or sandwiched between other materials. This can enhance the mechanical stability of the SAM. For example, the SAM can be disposed on a layered support.

[0186] The solid aerosol generating membrane can be cut or otherwise divided into multiple strips or slivers, which are then wrapped to form aerosol generating matrix strips for inclusion in aerosol generating articles.

[0187] Solid aerosol generating membranes can be aggregated to form aerosol generating matrix strips for inclusion in aerosol generating articles.

[0188] The solid aerosol generating membrane may have a total aerosol forming agent content of at least about 35% by weight, at least about 40% by weight, at least about 45% by weight, or at least about 40% by weight, based on the dry weight of the solid aerosol generating membrane.

[0189] Solid aerosol generating membranes may have a total aerosol forming agent content of less than or equal to about 60% by weight based on the dry weight of the solid aerosol generating membrane.

[0190] The solid aerosol generating membrane may have a total aerosol forming agent content of between about 35% and about 60% by weight, between about 40% and about 60% by weight, or between about 45% and about 60% by weight, based on the dry weight of the solid aerosol generating membrane.

[0191] The solid aerosol generating membrane may have a glycerol content of at least about 35% by weight, at least about 40% by weight, at least about 45% by weight, or at least about 40% by weight, based on the dry weight of the solid aerosol generating membrane.

[0193] The solid aerosol generating membrane may have a glycerol content of between about 35% and about 60% by weight, between about 40% and about 60% by weight, or between about 45% and about 60% by weight, based on the dry weight of the solid aerosol generating membrane.

[0194] Preferably, the solid aerosol generating matrix may contain nicotine. For example, the solid aerosol generating matrix may be a solid aerosol generating membrane containing nicotine.

[0195] The solid aerosol generating matrix may have a nicotine content of at least about 0.5% by weight, at least about 1% by weight, at least about 1.5% by weight, or at least about 2% by weight, based on the dry weight of the solid aerosol generating matrix.

[0196] The solid aerosol generating matrix may have a nicotine content of less than or equal to 10% by weight, less than or equal to 8% by weight, less than or equal to 6% by weight, or less than or equal to 4% by weight, based on the dry weight of the solid aerosol generating matrix.

[0197] In cases where the solid aerosol generating matrix contains nicotine bases or nicotine salts, the amounts of nicotine described herein are either the amount of free nicotine or the amount of protonated nicotine.

[0198] In some instances, the solid aerosol generating matrix may have a total aerosol forming agent content of at least about 35% by weight, at least about 40% by weight, at least about 45% by weight, or at least about 40% by weight, based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0199] In some instances, the solid aerosol generating matrix may have a total aerosol forming agent content of less than or equal to about 60% by weight based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0200] In some instances, the solid aerosol generating matrix may have a total aerosol forming agent content of between about 35% and about 60% by weight, between about 40% and about 60% by weight, or between about 45% and about 60% by weight, based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0201] In some instances, the solid aerosol generating matrix may have a glycerol content of at least about 35% by weight, at least about 40% by weight, at least about 45% by weight, or at least about 40% by weight, based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0202] In some instances, the solid aerosol generating matrix may have a glycerol content of less than or equal to about 60% by weight, based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0203] In some instances, the solid aerosol generating matrix may have a glycerol content between about 35% and about 60% by weight, between about 40% and about 60% by weight, or between about 45% and about 60% by weight, based on the dry weight of the solid aerosol generating matrix. This may be especially true when the aerosol generating matrix comprises a solid aerosol generating membrane (e.g., a solid aerosol generating membrane containing a cellulose-based reagent).

[0204] The aerosol-generating matrix strip may contain graphite.

[0205] The aerosol generating matrix strip may include thermally conductive particles. Advantageously, these particles can increase the thermal conductivity of the aerosol generating matrix strip. This increased thermal conductivity provides a more uniform temperature distribution across the aerosol generating matrix during use. This can result in a larger proportion of the aerosol generating matrix reaching sufficiently high temperatures to release volatile compounds, and thus leading to higher utilization efficiency of the aerosol generating matrix. Furthermore, the increased thermal conductivity of the aerosol generating matrix allows the heater (e.g., the heater of an aerosol generating device configured to heat the aerosol generating matrix) to operate at lower temperatures and therefore requires less power. Further, the increased thermal conductivity of the aerosol generating matrix allows the heater to heat the matrix to temperatures at which volatile compounds are released in a shorter time. Therefore, the increased thermal conductivity can reduce the time required to form an inhalable aerosol for the user.

[0206] Each thermally conductive particle in the matrix may have a thermal conductivity of at least 1 W / m Kelvin [W / (m·K)] in at least one direction at 25 degrees Celsius. For example, this thermal conductivity can be measured when the moisture content of the aerosol-generating matrix is ​​between 0% and 20% or between 5% and 15% (e.g., approximately 10%). This thermal conductivity can also be measured when the matrix contains 0 to 20% by weight or between 5 to 15% by weight (e.g., approximately 10% by weight) of water. The moisture content or water content of the matrix can be measured using titration. The moisture content or water content of the matrix can be measured using the Karl Fischer method.

[0207] Some or all of the thermally conductive particles may comprise one or more of graphite, expanded graphite, graphene, carbon nanotubes, charcoal, and diamond (such as synthetic diamond). Some or all of the thermally conductive particles may be graphite particles.

[0208] The aerosol generating matrix strip may contain thermally conductive particles at a dry weight percentage of between about 10% and about 90% by weight.

[0209] The aerosol generating matrix strip contains aerosol generating material along substantially its entire length. This aerosol generating material is capable of releasing volatile compounds that can generate aerosols upon heating.

[0210] The aerosol-generating matrix strip can contain nicotine along substantially its entire length. In other words, nicotine can be distributed along substantially its entire length. Nicotine can be distributed substantially uniformly along the entire length of the aerosol-generating matrix strip.

[0211] The aerosol generating matrix strip may contain an aerosol forming agent along substantially the entire length of the aerosol generating matrix strip. The aerosol forming agent may be distributed substantially uniformly along the entire length of the aerosol generating matrix strip.

[0212] An aerosol generating matrix strip may include one or more aerosol generating matrix segments. In the case where the aerosol generating matrix strip includes multiple aerosol generating matrix segments, each of the multiple aerosol generating matrix segments is in direct contact with at least one other segment of the multiple aerosol generating matrix segments.

[0213] An aerosol-generating matrix strip may include one or more aerosol-generating matrix segments, each of which contains nicotine. In this case, and where the aerosol-generating article includes additional segments containing plant material but not nicotine, these additional segments are not considered part of the aerosol-generating matrix strip.

[0214] An aerosol-generating matrix strip may include one or more aerosol-generating matrix segments, wherein each aerosol-generating matrix segment has a total aerosol-forming agent content of at least about 10% by weight on a dry weight basis. In this case, and where the aerosol-generating article includes additional segments containing plant material and the additional segments do not have a total aerosol-forming agent content of at least about 10% by weight on a dry weight basis, such additional segments are not considered part of the aerosol-generating matrix strip.

[0215] Each aerosol-generating matrix segment may have a glycerol content of at least about 10% by weight on a dry weight basis.

[0216] The aerosol generating matrix strip may include one or more aerosol generating matrix segments, wherein each aerosol generating matrix segment contains nicotine, and wherein each aerosol generating matrix segment has a total aerosol forming agent content of at least about 10% by weight on a dry weight basis.

[0217] An aerosol generation matrix strip may comprise a single aerosol generation matrix segment. When an aerosol generation matrix strip comprises a single aerosol generation matrix segment, the single aerosol generation matrix segment extends the entire length of the aerosol generation matrix strip. When an aerosol generation matrix strip comprises a single aerosol generation matrix segment, the properties of the aerosol generation matrix strip discussed herein also apply to the single aerosol generation matrix segment. An aerosol generation matrix strip may be composed of a single aerosol generation matrix segment.

[0218] An aerosol generating matrix strip may include multiple aerosol generating matrix segments, wherein each of the multiple aerosol generating matrix segments is in direct contact with at least one other segment of the multiple aerosol generating matrix segments. For example, an aerosol generating matrix strip may include two aerosol generating matrix segments: a first aerosol generating matrix segment and a second aerosol generating matrix segment in direct contact with the first aerosol generating matrix segment.

[0219] Each of the multiple aerosol-generating matrix segments may contain nicotine.

[0220] Each of the multiple aerosol-generating matrix segments may have a total aerosol-forming agent content of at least about 10% by weight on a dry weight basis. Each of the multiple aerosol-generating matrix segments may have a glycerol content of at least about 10% by weight on a dry weight basis.

[0221] For example, an aerosol generating matrix strip may include a plurality of aerosol generating matrix segments, wherein each of the plurality of aerosol generating matrix segments is in direct contact with at least one other segment of the plurality of aerosol generating matrix segments, wherein each of the plurality of aerosol generating matrix segments contains nicotine, and wherein each of the plurality of aerosol generating matrix segments has a total aerosol forming agent content of at least about 10% by weight on a dry weight basis.

[0222] One segment of a plurality of aerosol generating matrix segments can be separated from another segment of a plurality of aerosol generating matrix segments without the use of a non-aerosol generating element.

[0223] Multiple aerosol generating matrix segments can be adjacent to each other end-to-end. For example, an aerosol generating matrix strip may include a first aerosol generating matrix segment and a second aerosol generating matrix segment, wherein the upstream end of the second aerosol generating matrix segment is adjacent to the downstream end of the first aerosol generating matrix segment.

[0224] The length of the aerosol generating matrix strip can be equal to the sum of the lengths of each of the plurality of aerosol generating matrix segments. For example, the aerosol generating matrix strip may include a first aerosol generating matrix segment and a second aerosol generating matrix segment, wherein the length of the aerosol generating matrix strip is equal to the sum of the lengths of the first aerosol generating matrix segment and the second aerosol generating matrix segment. The sum of the lengths of the first aerosol generating matrix segment and the second aerosol generating matrix segment may be at least about 75% of the length of the aerosol-generated article.

[0225] Each of the multiple aerosol generation matrix segments can be substantially identical to each other.

[0226] Each of the multiple aerosol generation matrix segments may have substantially the same length. Each of the multiple aerosol generation matrix segments may have substantially the same shape. Each of the multiple aerosol generation matrix segments may have substantially the same size.

[0227] Each of the multiple aerosol generation matrix segments can have substantially the same composition.

[0228] Multiple aerosol generation matrix segments may include at least two aerosol generation matrix segments having compositions different from each other. Each of the multiple aerosol generation matrix segments may have a different composition.

[0229] The aerosol generating matrix strip can be located at the upstream end of the aerosol generating article. The aerosol generating matrix strip can extend from the upstream end of the aerosol generating article toward the downstream end of the aerosol generating article.

[0230] In the second and third aspects of the invention, the aerosol generating matrix strip may be located at the downstream end of the aerosol generating article. The aerosol generating matrix strip may extend from the downstream end of the aerosol generating article toward the upstream end of the aerosol generating article. The aerosol generating article strip may extend from the upstream end of the aerosol generating article to the downstream end of the aerosol generating article. The aerosol generating matrix strip may extend substantially the entire length of the aerosol generating article. The aerosol generating matrix strip may have a length substantially the same as the length of the aerosol generating article.

[0231] Aerosol-generating articles may include sensors. As used herein with reference to this invention, the term "sensor" refers to a material that can convert electromagnetic energy into heat. When located within a fluctuating electromagnetic field, eddy currents induced in the sensor cause heating of the sensor.

[0232] The receptor can be arranged to have thermal contact with the aerosol generation matrix strip. The receptor can also have direct contact with the aerosol generation matrix strip.

[0233] The receptors can be located within the aerosol-generating matrix strip.

[0234] The receptor can be formed from any material that can be inductively heated to a temperature sufficient to generate aerosols from the aerosol-generating matrix. The receptor can contain or be composed of ferromagnetic materials, such as ferromagnetic alloys, ferritic iron, ferromagnetic steel, or stainless steel. Suitable receptors may be aluminum or include aluminum.

[0235] The aerosol generating articles of the first, second, and third aspects of the present invention have a length of about 40 mm or less, and an aerosol generating matrix strip with a length of at least about 75% of the length of the aerosol generating article. In cases where the aerosol generating article includes one or more elements other than the aerosol generating matrix strip, the combined length of the one or more elements is relatively short.

[0236] The aerosol generating article of the first aspect of the present invention includes a downstream section located downstream of the aerosol generating matrix strip. The aerosol generating article of the aerosol generating system of the second aspect of the present invention may include a downstream section located downstream of the aerosol generating matrix strip. Each of a plurality of aerosol generating articles of the container of the third aspect of the present invention may include a downstream section located downstream of the aerosol generating matrix strip.

[0237] The downstream section helps prevent direct contact between the aerosol generating material of the aerosol generating matrix strip and certain components of the aerosol generating device when the aerosol generating article is inserted into and located within the aerosol generating device during its use. This helps prevent contamination of the aerosol generating material, which can adversely affect the quality and consistency of the aerosol delivered to the user.

[0238] The downstream section helps prevent aerosol-generating material from migrating from the aerosol-generating matrix strip, and any displaced aerosol-generating material from traveling through the downstream section and exiting the aerosol-generating article through its downstream end. This helps prevent aerosol-generating material residue in the aerosol-generating device after removal of the aerosol-generating article. Residual aerosol-generating material in the aerosol-generating device after removal can prevent or inhibit optimal function of the aerosol-generating device, potentially adversely affecting the quality and consistency of the aerosol delivered to the user.

[0239] After using the aerosol generating article, the aerosol generating strip may be hot. Providing a downstream section to the aerosol generating article avoids the user's contact with the aerosol generating matrix strip when removing the aerosol generating article from the aerosol generating device. After using the aerosol generating article, the user can hold the downstream section to facilitate removal of the aerosol generating article from the aerosol generating device.

[0240] The downstream section extends from the downstream end of the aerosol generation matrix strip to the downstream end of the aerosol generation product.

[0241] The downstream section may have a length of less than or equal to about 8 mm or less than or equal to about 5 mm. The downstream section may have a length of at least about 1 mm or at least about 3 mm. For example, the downstream section may have a length between about 3 mm and about 5 mm.

[0242] In some instances, the downstream section may have a length of less than or equal to about 1 mm or less than or equal to about 0.5 mm. This may be especially true when the downstream section includes a membrane, as discussed further below.

[0243] The ratio of the length of the downstream section to the length of the aerosol-generated article can be less than or equal to about 0.2, less than or equal to about 0.15, or less than or equal to about 0.1.

[0244] The downstream section may have a substantially circular cross-section. The downstream section may have a diameter substantially the same as the diameter of the aerosol-generating matrix strip. Preferably, the downstream section has a substantially constant diameter along its entire length.

[0245] The downstream section may include rod elements. The rod elements may be porous rod elements. The rod elements may be formed from solid cylindrical rod elements with a filled cross-section. Such rod elements may be referred to as "ordinary" elements. As mentioned above, the rod elements may be porous but not tubular in form and therefore do not provide longitudinal flow channels. The rod elements may have a substantially uniform cross-section. The rod elements may help reduce or prevent the migration of aerosol-generating material from the aerosol-generating matrix strip. The rod elements may help reduce or prevent any displaced aerosol-generating material from falling off the downstream end of the aerosol-generating article.

[0246] The rod elements in the downstream section can be adjacent to the aerosol-generated matrix strip.

[0247] The rod element can extend the entire length of the downstream section. An aerosol generating article may include a rod element extending from the downstream end of the aerosol generating matrix strip to the downstream end of the aerosol generating article.

[0248] The rod element can have a diameter that is substantially the same as the diameter of the aerosol generating matrix strip.

[0249] The rod element can be a cellulose acetate rod. The downstream section can also include cellulose acetate rods.

[0250] The downstream section may include hollow tubular elements. These hollow tubular elements can help cool the aerosols generated by the aerosol generation matrix strip. They can also help reduce or prevent the migration of aerosol-generating material from the aerosol generation matrix strip.

[0251] As used herein with reference to this invention, the term "hollow tubular element" is used to refer to a generally cylindrical element having a lumen along its longitudinal axis. The hollow tubular element may have a substantially circular, oval, or elliptical cross-section. The lumen may have a substantially circular, oval, or elliptical cross-section. In particular, the term "hollow tubular element" is used to refer to an element defining at least one airflow conduit that establishes uninterrupted fluid communication between an upstream end and a downstream end of the hollow tubular element.

[0252] In the context of this invention, the hollow tubular element provides an unrestricted flow path. This means that the hollow tubular element provides a negligible level of suction resistance (RTD). As used herein with reference to this invention, the term "negligible level of RTD" is used to describe hollow tubular elements with an RTD less than 1 mmH2O / 10 mm in length, less than 0.4 mmH2O / 10 mm in length, or less than 0.1 mmH2O / 10 mm in length. Therefore, the flow path should be free of any components that would impede the flow of air in the longitudinal direction. Preferably, the flow path is substantially empty.

[0253] The hollow tubular element in the downstream section can be adjacent to the aerosol-generated matrix strip.

[0254] The hollow tubular element in the downstream section may extend the entire length of the downstream section. The aerosol-generating article may include a hollow tubular element extending from the downstream end of the aerosol-generating matrix strip to the downstream end of the aerosol-generating article.

[0255] The hollow tubular element in the downstream section may have a diameter that is substantially the same as the diameter of the aerosol generating matrix strip.

[0256] The hollow tubular element of the downstream section can be formed from any suitable material or combination of materials. For example, the hollow tubular element of the downstream section can be formed from one or more materials selected from: cellulose acetate; paper-based materials, such as paper or cardboard; and polymeric materials, such as low-density polyethylene (LDPE). Other suitable materials include polyhydroxyalkanoate (PHA) fibers.

[0257] The downstream section may include non-tobacco plant particles. For example, the downstream section may include particles selected from rosemary particles, star anise particles, ginger particles, clove particles, eucalyptus particles, or combinations thereof.

[0258] During use of the aerosol-generating article, the downstream section may be indirectly heated. During use of the aerosol-generating article, non-tobacco plant particles may generate one or more volatile flavor compounds that contribute to the sensory output of the aerosol-generating article. If the downstream section includes a rod element, the rod element may include non-tobacco plant particles. If the downstream section includes a hollow tubular element, the hollow tubular element may include non-tobacco plant particles.

[0259] The downstream section may contain flavorings. Suitable flavorings include, but are not limited to: menthol; peppermint, such as peppermint and spearmint; chocolate; licorice; citrus and other fruit flavorings; gamma-octanol; vanillin; ethyl vanillin; breath freshener flavorings; condiment flavorings, such as cinnamon; methyl salicylate; linalool; bergamot oil; geranium oil; lemon oil; ginger oil; and tobacco flavorings. If the downstream section includes a rod element, the rod element may contain flavorings. If the downstream section includes a hollow tubular element, the hollow tubular element may contain flavorings.

[0260] The downstream section may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The downstream section may be substantially free of aerosol forming agents. In other words, the downstream section may contain about 0% by weight of aerosol forming agents on a dry weight basis.

[0261] In cases where the downstream section includes rod elements, the rod elements may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The rod elements may be substantially free of aerosol forming agents.

[0262] In cases where the downstream section includes a hollow tubular element, the hollow tubular element may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The hollow tubular element may be substantially free of aerosol forming agents.

[0263] The downstream section may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The downstream section may be substantially nicotine-free. In other words, the downstream section may contain about 0% by weight of nicotine on a dry weight basis.

[0264] In cases where the downstream section includes a rod element, the rod element may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The rod element may be substantially nicotine-free.

[0265] In cases where the downstream section includes a hollow tubular element, the hollow tubular element may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The hollow tubular element may be substantially nicotine-free.

[0266] The downstream section may include a membrane. The membrane in the downstream section can be used to seal the downstream end of the aerosol generating matrix strip. The membrane in the downstream section can substantially prevent the aerosol generating material of the aerosol generating matrix strip from leaving the aerosol generating article through the downstream end of the aerosol generating article. The membrane in the downstream section can substantially prevent airflow through the downstream end of the aerosol generating matrix strip. This can help improve the shelf life of the aerosol generating article, as well as the quality and consistency of the aerosol delivered to the user.

[0267] The downstream section of the membrane can be adjacent to the downstream end face of the aerosol generation matrix strip. The downstream section of the membrane can substantially cover the entire downstream end face of the aerosol generation matrix strip.

[0268] The membrane in the downstream section can be essentially air-impermeable.

[0269] The membrane in the downstream section can be configured to be removable from the aerosol-generating article. The membrane in the downstream section can be removed from the aerosol-generating article before its use.

[0270] The membrane in the downstream section may have a length of less than or equal to about 1 mm or less than or equal to about 0.5 mm.

[0271] The membrane in the downstream section can extend the entire length of the downstream section.

[0272] The downstream section may be defined by packaging such as stick packaging.

[0273] The downstream section can be connected to the aerosol generation matrix strip with the help of the outer packaging.

[0274] According to the second and third aspects of the present invention, the aerosol-generating articles may not include a downstream section.

[0275] Aerosol-generating articles may include an upstream section located upstream of the aerosol-generating matrix strip.

[0276] The upstream section helps prevent direct contact between the aerosol generating material of the aerosol generating matrix strip and certain components of the aerosol generating device when the aerosol generating article is inserted into and located within the aerosol generating device during its use. This helps prevent contamination of the aerosol generating material, which can adversely affect the quality and consistency of the aerosol delivered to the user.

[0277] The upstream section helps prevent aerosol-generating material from migrating from the aerosol-generating matrix strip, and any displaced aerosol-generating material from traveling through the upstream section and exiting the aerosol-generating article through its upstream end. This helps prevent aerosol-generating material residue in the aerosol-generating device after removal of the aerosol-generating article. Residual aerosol-generating material in the aerosol-generating device after removal can prevent or inhibit optimal function of the aerosol-generating device, which may adversely affect the quality and consistency of the aerosol delivered to the user.

[0278] After using the aerosol generating article, the aerosol generating strip may be hot. Providing an upstream section to the aerosol generating article avoids the user's contact with the aerosol generating matrix strip when removing the aerosol generating article from the aerosol generating device. After using the aerosol generating article, the user can grasp the upstream section to facilitate removal of the aerosol generating article from the aerosol generating device.

[0279] The upstream section extends from the upstream end of the aerosol-generated product to the upstream end of the aerosol-generated matrix strip.

[0280] Aerosol-generated products can include both upstream and downstream sections.

[0281] The upstream section may have a length of less than or equal to about 8 mm or less than or equal to about 5 mm. The upstream section may have a length of at least about 1 mm or at least about 3 mm. For example, the upstream section may have a length between about 3 mm and about 5 mm.

[0282] In some instances, the upstream section may have a length of less than or equal to about 1 mm or less than or equal to about 0.5 mm. This may be especially true when the upstream section includes a membrane, as discussed further below.

[0283] The ratio of the length of the upstream section to the length of the aerosol-generated product can be less than or equal to about 0.2, less than or equal to about 0.15, or less than or equal to about 0.1.

[0284] The upstream section may have a substantially circular cross-section. The upstream section may have a diameter substantially the same as the diameter of the aerosol-generating matrix strip. Preferably, the upstream section has a substantially constant diameter along its entire length.

[0285] The upstream section may include rod elements. These rod elements may be porous. They may be formed from solid cylindrical rod elements with a filled cross-section. Such rod elements may be referred to as "ordinary" elements. As mentioned above, the rod elements may be porous but not tubular in form and therefore do not provide longitudinal flow channels. The rod elements may have a substantially uniform cross-section. The rod elements may help reduce or prevent the migration of aerosol-generating material from the aerosol-generating matrix strip. The rod elements may help reduce or prevent any displaced aerosol-generating material from falling off the upstream end of the aerosol-generating article.

[0286] The rod elements in the upstream section can be adjacent to aerosols to generate matrix strips.

[0287] The rod element may extend the entire length of the upstream section. An aerosol generating article may include a rod element extending from the upstream end of the aerosol generating article to the upstream end of the aerosol generating matrix strip.

[0289] The rod element can be a cellulose acetate rod. The upstream section can include cellulose acetate rods.

[0290] The upstream section may include hollow tubular elements. Hollow tubular elements can help reduce or prevent the migration of aerosol-generating materials from the aerosol-generating matrix strip.

[0291] The hollow tubular element in the upstream section can be adjacent to the aerosol to form a matrix strip.

[0292] The hollow tubular element in the upstream section can extend the entire length of the upstream section. The aerosol generating article may include a hollow tubular element extending from the upstream end of the aerosol generating article to the upstream end of the aerosol generating matrix strip.

[0293] The hollow tubular element in the upstream section may have a diameter that is substantially the same as the diameter of the aerosol-generating matrix strip.

[0294] The hollow tubular element of the upstream section can be formed from any suitable material or combination of materials. For example, the hollow tubular element of the upstream section can be formed from one or more materials selected from: cellulose acetate; paper-based materials, such as paper or cardboard; and polymeric materials, such as low-density polyethylene (LDPE). Other suitable materials include polyhydroxyalkanoate (PHA) fibers.

[0295] The upstream section may include non-tobacco plant particles. For example, the upstream section may include particles selected from rosemary particles, star anise particles, ginger particles, clove particles, eucalyptus particles, or combinations thereof.

[0296] During use of the aerosol-generating article, the upstream section may be indirectly heated. During use of the aerosol-generating article, non-tobacco plant particles may generate one or more volatile flavor compounds that contribute to the sensory output of the aerosol-generating article. If the upstream section includes a rod element, the rod element may include non-tobacco plant particles. If the upstream section includes a hollow tubular element, the hollow tubular element may include non-tobacco plant particles.

[0297] The upstream section may contain flavorings. Suitable flavorings include, but are not limited to: menthol; peppermint, such as peppermint and spearmint; chocolate; licorice; citrus and other fruit flavorings; gamma-octanol; vanillin; ethyl vanillin; breath freshener flavorings; condiment flavorings, such as cinnamon; methyl salicylate; linalool; bergamot oil; geranium oil; lemon oil; ginger oil; and tobacco flavorings. If the upstream section includes a rod element, the rod element may contain flavorings. If the upstream section includes a hollow tubular element, the hollow tubular element may contain flavorings.

[0298] The upstream section may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The upstream section may be substantially free of aerosol forming agents. In other words, the upstream section may contain about 0% by weight of aerosol forming agents on a dry weight basis.

[0299] In the case where the upstream section includes rod elements, the rod elements may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The rod elements may be substantially free of aerosol forming agents.

[0300] In cases where the upstream section includes hollow tubular elements, the hollow tubular elements may have a total aerosol forming agent content of less than or equal to about 1% by weight on a dry weight basis. The hollow tubular elements may be substantially free of aerosol forming agents.

[0301] The upstream section may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The downstream section may be substantially nicotine-free. In other words, the downstream section may contain about 0% by weight of nicotine on a dry weight basis.

[0302] In the case where the upstream section includes a rod element, the rod element may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The rod element may be substantially nicotine-free.

[0303] When the upstream section includes a hollow tubular element, the hollow tubular element may have a nicotine content of less than or equal to about 0.1% by weight on a dry weight basis. The hollow tubular element may be substantially nicotine-free. The upstream section may include a membrane. The membrane of the upstream section may be used to seal the upstream end of the aerosol generating matrix strip. The membrane of the upstream section can substantially prevent the aerosol generating material of the aerosol generating matrix strip from leaving the aerosol generating article through the upstream end of the aerosol generating article. The membrane of the upstream section can substantially prevent airflow through the upstream end of the aerosol generating matrix strip. This can help improve the shelf life of the aerosol generating article, as well as the quality and consistency of the aerosol delivered to the user.

[0304] The upstream section of the membrane can be adjacent to the upstream end face of the aerosol generation matrix strip. The upstream section of the membrane can cover essentially the entire upstream end face of the aerosol generation matrix strip.

[0305] The membrane in the upstream section can be essentially air-impermeable.

[0306] The membrane in the upstream section can be configured to be removable from the aerosol-generating article. The membrane can be removed from the aerosol-generating article before its use.

[0307] The membrane in the upstream section may have a length of less than or equal to about 1 mm or less than or equal to about 0.5 mm.

[0308] The membrane in the upstream section can extend the entire length of the upstream section.

[0309] The upstream section may be defined by packaging such as stick packaging.

[0310] The upstream section can be connected to the aerosol generation matrix strip by means of the outer packaging.

[0311] In the case where the aerosol generating article includes both an upstream section and a downstream section, the upstream section can be connected to both the aerosol generating matrix strip and the downstream section by means of an outer packaging material.

[0312] Aerosol-generated products may exclude the upstream section.

[0313] In the case of an aerosol-generating article comprising an upstream segment and a downstream segment, the upstream and downstream segments may have different lengths. This provides the user with visual indication to distinguish the upstream and downstream ends of the aerosol-generating article. The length of the upstream segment may be shorter than the length of the downstream segment.

[0314] Aerosol generating articles may include a transversely symmetrical plane. This simplifies the use of aerosol generating articles and aerosol generating devices because the orientation of the aerosol generating article when inserted into the aerosol generating device may not affect aerosol generation and delivery to the user. This helps ensure a consistent user experience from one aerosol generating article to another.

[0315] According to a second aspect of the invention, an aerosol generation system is provided, comprising: an aerosol generation article and an aerosol generation apparatus, wherein the aerosol generation article includes an aerosol generation matrix strip containing nicotine and having a total aerosol forming agent content of at least about 10% by weight on a dry weight basis, wherein the aerosol generation article has a length less than or equal to about 40 mm, wherein the ratio of the length of the aerosol generation matrix strip to the length of the aerosol generation article is at least about 0.75, wherein the aerosol generation apparatus includes a heating chamber for receiving the aerosol generation article and a heater for heating the aerosol generation matrix strip of the aerosol generation article when the aerosol generation article is received in the heating chamber, and wherein the heating chamber of the aerosol generation apparatus has a length that deviates from the length of the aerosol generation article by about 10%.

[0316] As described above, the aerosol generating article of the aerosol generating system according to the second aspect of the present invention may have any of the features of the aerosol generating article described herein. The aerosol generating article of the aerosol generating system according to the second aspect of the present invention may also be the aerosol generating article according to the first aspect of the present invention.

[0317] The heating chamber of an aerosol generating device can be referred to as the cavity of the aerosol generating device.

[0318] The heating chamber can be essentially cylindrical.

[0319] A heating chamber for an aerosol generating apparatus having a length within approximately 10% of the length of the aerosol-generating article can improve the efficiency of heating the aerosol-generating matrix of the aerosol-generating article.

[0320] The heating chamber of the aerosol generating apparatus may have a length that deviates from the length of the aerosol-generated product by approximately 5%.

[0321] The heating chamber of the aerosol generating apparatus can have a length substantially the same as the length of the aerosol-generated product. This allows for a close fit between the aerosol-generated product and the heating chamber of the aerosol generating apparatus.

[0322] The heating chamber of the aerosol generating device may have a length greater than the length of the aerosol-generated product.

[0323] The length of the heating chamber is such that when the aerosol-generating article is received inside the heating chamber, at least approximately 90% of its length is contained within the heating chamber. The length of the heating chamber is also such that when the aerosol-generating article is received inside the heating chamber, it is enclosed within the heating chamber.

[0324] The diameter of the heating chamber can deviate from the diameter of the aerosol-generating article by approximately 10%, or by approximately 5%. This can improve the efficiency of heating the aerosol-generating matrix of the aerosol-generating article.

[0325] The diameter of the heating chamber can be substantially the same as the diameter of the aerosol-generated product. This allows for a tight fit between the aerosol-generated product and the heating chamber of the aerosol generating apparatus.

[0326] The diameter of the heating chamber can be larger than the diameter of the aerosol-generated product.

[0327] Aerosol generating apparatus may include a housing that defines a heating chamber.

[0328] The aerosol generating apparatus may include a peripheral wall. The peripheral wall may define a heating chamber. The peripheral wall may be configured to engage with the aerosol generating article received in the heating chamber in a close-fitting manner, such that there is substantially no gap or empty space between the peripheral wall and the aerosol generating article received in the heating chamber.

[0329] The heater can be any suitable type of heater. Preferably, the heater is an external heater.

[0330] When the aerosol-generating article is received within the aerosol-generating apparatus, a heater can be externally heated. Such an external heater can be configured to define the aerosol-generating article when it is inserted into or received within the aerosol-generating apparatus. The external heater can also be configured to define substantially the entire length of the aerosol-generating matrix strip of the aerosol-generating article when it is inserted into or received within the aerosol-generating apparatus.

[0331] An external heater can define the heating chamber.

[0332] In some instances, the heater may be arranged to be inserted into the aerosol generating matrix strip of the aerosol generating article when the aerosol generating article is received in the heating chamber.

[0333] The heater can be positioned inside the heating chamber.

[0334] A heater may include at least one heating element. For example, a heater may include multiple heating elements.

[0335] The heating element can be a resistance heating element.

[0336] The heater may include an induction heating device. The induction heating device may include an inductor coil.

[0337] The heater may include an induction heating element. The induction heating element may be a sensor.
