Description

Technical Field

[0001] This disclosure relates to an aerosol generation system. The system includes an aerosol generation apparatus and an aerosol generation article, the aerosol generation article including an aerosol forming matrix. Background Technology

[0002] Typical aerosol-generating articles can resemble regular cigarettes. For example, such aerosol-generating articles can be substantially cylindrical and include an aerosol-forming matrix and other components (such as mouthpiece filter elements and cooling elements) arranged in strips and wrapped in cigarette paper. The dimensions of typical aerosol-generating articles are generally similar to those of regular cigarettes.

[0003] During use, the aerosol-generating article is typically connected to an aerosol-generating device, and then the aerosol-forming matrix is ​​heated by the aerosol-generating device.

[0004] However, a significant portion of the aerosol-forming matrix in these cylindrical aerosol-generating articles may not be adequately heated to form an aerosol during use. This is undesirable because the insufficiently heated portions of the aerosol-forming matrix affect the manufacturing and transportation costs of the aerosol-generating article, but not the aerosol delivered to the end user. This is likely to occur regardless of how the aerosol-forming matrix is ​​heated—for example, whether a resistance heater or an induction heater is used—and whether the aerosol-forming matrix is ​​heated internally or externally. Furthermore, the components of these cylindrical aerosol-generating articles typically need to have the same or very similar outer diameters so that they can be assembled together, accurately positioned coaxially aligned, and wrapped in cigarette paper. This can lead to increased manufacturing costs and complexity.

[0005] Furthermore, in some aerosol generation systems, the time between the initial heater start-up and the aerosol-forming matrix reaching a sufficiently high temperature to form an aerosol (sometimes referred to as the time to the first puff) is too long. Alternatively or additionally, in some aerosol generation systems, excessive aerosol-forming matrix is ​​consumed too quickly after it has reached a sufficiently high temperature to form an aerosol. This can mean that the flavor of the aerosol delivered to the user diminishes rapidly after the first puff or the first few puffs. Summary of the Invention

[0006] The purpose of this disclosure is to provide an aerosol generation system in which a significant portion of the aerosol-forming matrix of the aerosol-generating article is sufficiently heated during use to form an aerosol. Another purpose of this disclosure is to provide an aerosol-generating article that can be manufactured relatively efficiently and inexpensively. A further purpose of this disclosure is to provide an aerosol generation system in which the time to the first suction is shortened. Yet another purpose of this disclosure is to provide an aerosol generation system in which the aerosol-forming matrix is ​​not consumed too quickly.

[0007] According to this disclosure, an aerosol generation system is provided, comprising an aerosol generation article and an aerosol generation apparatus. The aerosol generation article may include at least one aerosol forming matrix. The aerosol generation article may have an article length, an article width, and an article thickness, or be defined by the article length, article width, and article thickness. The article length may be at least twice the article thickness. The article width may be at least twice the article thickness. The aerosol generation apparatus may include a heating chamber for receiving at least a portion of the aerosol generation article. The aerosol generation apparatus may include at least one heater. The at least one heater may define a heating zone within the heating chamber. When the aerosol generation article is fully received in the heating chamber of the aerosol generation apparatus, 10% to 90%, preferably 20% to 80% of the total mass of at least one aerosol forming matrix may be located within the heating zone.

[0008] Therefore, according to a first aspect of this disclosure, an aerosol generation system is provided, comprising an aerosol generation article and an aerosol generation apparatus. The aerosol generation article includes at least one aerosol forming matrix. The aerosol generation article is defined by an article length, an article width, and an article thickness, wherein the article length and article width are at least twice the article thickness. The aerosol generation apparatus includes a heating chamber for receiving at least a portion of the aerosol generation article. The aerosol generation apparatus includes at least one heater, which defines a heating zone within the heating chamber. When the aerosol generation article is fully received in the heating chamber of the aerosol generation apparatus, 10% to 90%, preferably 20% to 80% of the total mass of at least one aerosol forming matrix is ​​located within the heating zone.

[0009] Advantageously, compared to a system where 100% of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone, by placing only up to 80% of the total mass of at least one aerosol-forming matrix within the heating zone when the aerosol-forming article is fully received in the heating chamber, a larger proportion of the heat energy supplied by the heater is transferred to the smaller mass of aerosol-forming material when the heater is first turned on. This means that the portion of the aerosol-forming matrix within the heating zone can reach a sufficiently high temperature to form an aerosol more quickly. Conversely, the portion of at least one aerosol-forming matrix outside the heating zone may require a longer time to reach a sufficiently high temperature to form an aerosol. Therefore, this portion of the at least one aerosol-forming matrix outside the heating zone can be able to release high-quality aerosols later during the use of the aerosol-forming system. Thus, the system can reduce the time to the first suction and delay the depletion of the aerosol-forming matrix.

[0010] As described above, the apparatus includes a heating chamber for receiving at least a portion of the article. The heating chamber may or may not receive the entire article. Therefore, as will be understood by those skilled in the art upon reading this disclosure, the statement that the article is completely received in the heating chamber does not mean that the entire article is received in the heating chamber. Rather, as will be understood by those skilled in the art upon reading this disclosure, the statement that the article is completely received in the heating chamber may mean that the article is received in the heating chamber to the maximum extent that the article can be received in the heating chamber. As discussed later, this may be when the upstream end of the article abuts a stop surface of the heating chamber. This stop surface may be the upstream end of the heating chamber or the surface of another component within the heating chamber to prevent the aerosol-generating article from moving further into the heating chamber. When the aerosol-generating article is “completely received” in the heating chamber, a portion of the aerosol-generating article may protrude from the heating chamber opening of the heating chamber. This may occur, for example, when the length of the aerosol-generating article is greater than the length of the heating chamber, or when the length of the aerosol-generating article is greater than the distance between the downstream end of the heating chamber and the surface within the heating chamber that prevents the article from moving further into the heating chamber.

[0011] At least one heater may include all heaters of the apparatus or all heaters of the apparatus configured to heat at least one aerosol-forming matrix to form an aerosol. A heating zone may be defined by all heaters of the apparatus or all heaters of the apparatus configured to heat at least one aerosol-forming matrix to form an aerosol. At least one aerosol-forming matrix may include all aerosol-forming materials in the article or all aerosol-forming materials in the article configured to be heated during use. The only aerosol-forming material in the article may be at least one aerosol-forming matrix. The article may contain no aerosol-forming material other than at least one aerosol-forming matrix. The total mass of at least one aerosol-forming matrix may be the total mass of all aerosol-forming materials in the article, or the total mass of all aerosol-forming materials in the article configured to be heated during use.

[0012] According to a second aspect of this disclosure, an aerosol generating article is also provided. The article can be used in an aerosol generating system, such as the system described above or the system of the first aspect. The article can be used with an aerosol generating apparatus, for example, to generate aerosols.

[0013] According to a third aspect of this disclosure, an aerosol generating apparatus is also provided. This apparatus can be used in an aerosol generating system, such as the system described above or the system of the first aspect. The apparatus can be used with aerosol generating articles, such as those according to the second aspect, for example, to generate aerosols.

[0014] Features described with respect to one aspect may be applicable to another. For example, features described with respect to an article of manufacture in the first aspect may be applicable to an article of manufacture in the second aspect. Similarly, features described with respect to an apparatus in the first aspect may be applicable to an apparatus in the third aspect.

[0015] The system can be configured such that during use, for example throughout the entire use process, at least a portion of the aerosol-forming matrix, such as at least 20% or 30% of the total mass of the aerosol-forming matrix, is never located within the heating zone.

[0016] The heating chamber may define a heating chamber opening. Articles can be received in the heating chamber through this opening. The heating chamber opening may be substantially rectangular in shape. The area of ​​the heating chamber opening may be no more than 20% or 10% larger than the area defined by the width and thickness of the article. When the article is fully received in the heating chamber, it can be held in place by friction. Advantageously, such friction or tight fit can allow efficient heat transfer from at least one heater to at least one substrate.

[0017] The heating chamber may have or define at least a partially closed end. The closed end may be opposite the heating chamber opening. The heating chamber may include a stop surface. The at least partially closed end may include a stop surface. The stop surface prevents the article from being received beyond the fully received position in the heating chamber. When the article is fully received in the heating chamber, the stop surface may be adjacent to the article, for example, at the upstream end of the article. Advantageously, when the article is fully received in the heating chamber, the use of the stop surface can ensure that the desired percentage of the total mass of the aerosol-forming matrix is ​​located within the heating zone.

[0018] Optionally, at least one heater is or includes at least one substantially flat or planar heater. Optionally, at least one heater includes a heating surface, such as a substantially flat or planar heating surface. Advantageously, a flat or planar heating surface can efficiently transfer heat to the substantially flat or planar aerosol forming matrix.

[0019] The heating surface may be defined by its length and width. Optionally, the inner surface of the heating chamber is at least a portion of or includes at least a portion of the heating surface. Advantageously, having the inner surface of the heating chamber as at least a portion of or including at least a portion of the heating surface allows for contact between the article or substrate and the heating surface, or minimizes the distance between the article or substrate and the heating surface. Advantageously, this allows for efficient heat transfer.

[0020] Optionally, when the aerosol-generated article is fully received in the heating chamber of the aerosol-generating apparatus, the length of the heating surface is substantially aligned with the length of the article. Optionally, when the aerosol-generated article is fully received in the heating chamber of the aerosol-generating apparatus, the width of the heating surface is substantially aligned with the width of the article. Advantageously, this alignment allows heat to be efficiently transferred from at least one heater to the article. Alternatively or additionally, this alignment can minimize overheating or underheating of the outer periphery of the article or matrix due to at least one heater extending beyond or not reaching the outer periphery.

[0021] Optionally, at least one aerosol forming matrix includes or is composed of a first aerosol forming matrix. The first aerosol forming matrix may have a first matrix length, a first matrix width, and a first matrix thickness, or be defined by the first matrix length, the first matrix width, and the first matrix thickness. Optionally, the first matrix length is at least twice the first matrix thickness. Optionally, the first matrix width is at least twice the first matrix thickness. The first aerosol forming matrix may be a rod comprising aerosol forming material. The first aerosol forming matrix may be substantially prismatic in shape, such as a cuboid or prism.

[0022] Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the length of the heating surface is substantially aligned with the length of the first matrix. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the width of the heating surface is substantially aligned with the width of the first matrix. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the thickness of the first matrix extends in a direction substantially perpendicular to one or both of the length and width of the heating surface. Advantageously, this alignment allows heat to be efficiently transferred from at least one heater to the first matrix. Alternatively or additionally, this alignment can minimize overheating or underheating of the outer periphery of the first matrix due to at least one heater extending beyond or not reaching the outer periphery.

[0023] Optionally, when the aerosol-generating article is completely received in the heating chamber of the aerosol-generating apparatus, at least 30%, 40%, 50%, or 60% of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is completely received in the heating chamber of the aerosol-generating apparatus, no more than 70%, 60%, 50%, or 40% of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the percentage of the total mass of at least one aerosol-forming matrix located in the heating zone is between 30% and 80%, or between 40% and 80%, or between 50% and 80%, or between 60% and 80%, or between 30% and 70%, or between 40% and 70%, or between 50% and 70%, or between 60% and 70%, or between 30% and 60%, or between 40% and 60%, or between 50% and 60%, or between 30% and 50%, or between 40% and 50%, or between 30% and 40%.

[0024] Particularly preferred is that, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 55%, for example, 55% to 70% of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. It has been found that this range can provide a suitable delay for the brief time to the first aspiration and for the formation of aerosols from the matrix outside the heating zone.

[0025] Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located outside the heating zone. It may be preferred to position the upstream portion of the matrix within the heating zone, as this portion of the matrix is ​​most likely to reach the highest temperature during use, and by selecting this portion as the upstream portion, the aerosol generated from this portion will have more time and distance to cool before reaching the downstream user. Alternatively or additionally, warm air or aerosol from upstream can flow over or through the downstream portion of the matrix. This can advantageously help to warm the downstream portion of the matrix, especially if that portion is located outside the heating zone.

[0026] Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the upstream end of any one, two, or all three of at least one heater, heating zone, and heating surface is aligned with a position no more than 20, 10, or 5 mm from the upstream end of at least one aerosol-forming matrix. Optionally, the upstream end of any one, two, or all three of at least one heater, heating zone, and heating surface is substantially aligned with the upstream end of at least one aerosol-forming matrix. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, the downstream end of any one, two, or all three of at least one heater, heating zone, and heating surface is aligned with a position at least 2, 5, 10, or 20 mm from the downstream end of the aerosol-forming matrix. Advantageously, this arrangement allows for efficient heat transfer to the matrix while positioning the upstream portion of the matrix within the heating zone and the downstream portion of the matrix outside the heating zone.

[0027] Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber of the aerosol-generating apparatus, at least 80% or 90%, for example 100%, of the total mass of at least one aerosol-forming matrix is ​​located outside the heating zone. Positioning the downstream portion of the matrix within the heating zone may be preferred because this reduces the time to the first aspiration. This may be because there is little or no matrix further downstream that would absorb heat or aerosol droplets as the generated aerosol flows toward the user. Alternatively or additionally, cold air flowing through the article may flow over or through the upstream portion of the matrix. This can advantageously further delay heat diffusion from the downstream section to the upstream section. This can advantageously allow for the formation of more aerosols or flavor later in the process of use.

[0028] At least one heater may be configured to heat portions of the heating zone separately, or to heat portions of the heating zone separately to the operating temperature. At least one heater may be configured to heat a first portion of the heating zone during a first stage, for example, to heat the first portion of the heating zone to the operating temperature, but not to heat a second portion of the heating zone, for example, not to heat the second portion of the heating zone to the operating temperature. At least one heater may be configured to heat a second portion of the heating zone during a second stage, for example, to heat the second portion of the heating zone to the operating temperature. The at least one heater may include at least two, three, or five heaters or heating surfaces. Each heater or heating surface may be activated or heated to the operating temperature individually. The first heater or heating surface of the at least one heater may be configured to heat the first portion of the heating zone. The second heater or heating surface of the at least one heater may be configured to heat the second portion of the heating zone.

[0029] In the context of the preceding paragraphs, the term "operating temperature" can refer to a temperature high enough to cause an aerosol-forming matrix, such as an aerosol-forming matrix of an article, to form an aerosol. The term "operating temperature" can refer to a temperature of at least 100, 150, 200, or 250 degrees Celsius. The term "operating temperature" can refer to a temperature not exceeding 800, 500, or 300 degrees Celsius. The term "operating temperature" can refer to a temperature between 100 and 800 degrees Celsius, or between 100 and 500 degrees Celsius, or between 100 and 300 degrees Celsius, or between 150 and 800 degrees Celsius, or between 150 and 500 degrees Celsius, or between 150 and 300 degrees Celsius.

[0030] The second stage may occur after the first stage. The first and second stages may occur during the same usage process. The first part may include 30% to 70% of the heated zone. The second part may include 30% to 70% of the heated zone.

[0031] Advantageously, the heating portion of the heating zone, as described above, can further reduce the time to the first puff because of the even smaller mass of the initially heated matrix. Alternatively or additionally, this can allow for a longer period of aerosol or flavor generation during use, since heating some portions of the matrix to a sufficiently high temperature to form an aerosol is delayed.

[0032] Optionally, at least one aerosol-forming matrix includes or is composed of a positionable aerosol-forming matrix. Optionally, the article includes a cavity, for example, for a positionable aerosol-forming matrix. Optionally, the positionable aerosol-forming matrix can be positioned within the article, for example, within a cavity of the article. Optionally, the positionable aerosol-forming matrix can be positioned within the aerosol-generating article relative to at least one other component of the aerosol-generating article, for example, relative to a cavity of the aerosol-generating article. Advantageously, this allows adjustment of the percentage of the total mass of at least one matrix within the heating zone when the article is fully received in the heating chamber. This can affect aerosol generation during use, for example, the time to the first aspiration or how long the matrix can continue to produce high-quality aerosols and flavor.

[0033] Optionally, the locatable aerosol-forming matrix can be positioned by the user within the aerosol-generating article, for example, before the aerosol-generating article is received in the heating chamber. Optionally, the locatable aerosol-forming matrix can be positioned within the aerosol-generating article to vary the percentage of the locatable aerosol-forming matrix located within the heating zone when the aerosol-generating article is fully received in the heating chamber. Advantageously, this allows the user to adjust the percentage of the total mass of at least one matrix within the heating zone when the article is fully received in the heating chamber.

[0034] Optionally, the locatable aerosol-forming matrix is ​​locatable in the aerosol-generating article at at least a first position and a second position different from the first position. Optionally, when the aerosol-generating article is fully received in the heating chamber and the locatable aerosol-forming matrix is ​​in the first position, a percentage of the locatable aerosol-forming matrix at the first position is located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber and the locatable aerosol-forming matrix is ​​in the second position, a percentage of the locatable aerosol-forming matrix at the second position is located within the heating zone. The first position percentage may differ from the second position percentage. Optionally, the first position percentage differs from the second position percentage by at least 10%, 20%, or 30%. Advantageously, this allows adjustment of the percentage of the total mass of at least one matrix within the heating zone when the article is fully received in the heating chamber.

[0035] The article may include a holding device for holding a positionable aerosol forming matrix in a specific location. For example, the article may include an adhesive region for adhering to the surface of the positionable aerosol forming matrix. The adhesive region may be located in or near a cavity of the article. The adhesive region may be located on a surface defining the boundary of the cavity. The adhesive region may be located on the upper surface of the base of the article. The adhesive region may be larger than the surface area of ​​the positionable aerosol forming matrix. Advantageously, this provides a user with an easy way to position the positionable aerosol forming matrix.

[0036] Optionally, the aerosol-generating article includes at least one indicator configured to indicate the positional location of the positionable aerosol-forming matrix within the aerosol-generating article. Advantageously, this reduces the risk of the positionable matrix being incorrectly positioned.

[0037] Optionally, the aerosol generating article includes at least one indicator configured to indicate how the position or positional change of the positionable aerosol-forming matrix in the aerosol generating article affects the use of the aerosol generating article in the aerosol generating system. Advantageously, this informs the user how the position or positional change of the positionable matrix can affect use. Therefore, the user can advantageously position the positionable matrix in a location that will provide them with a more desirable experience during use.

[0038] Optionally, the aerosol generating apparatus is configured to estimate or determine the location of a positionable aerosol-forming matrix in the aerosol-generating article. Optionally, the aerosol generating apparatus is configured to control the heating profile of at least one heater based at least in part on the location or estimated or determined location of the positionable aerosol-forming matrix in the aerosol-generating article. Advantageously, this can allow for customization of the experience depending on the location of the matrix. This could be a simple way for users to customize their experience.

[0039] Users can input the location of the positionable aerosol-forming matrix into the aerosol generating device. Alternatively, the device can be configured to determine the location of the positionable aerosol-forming matrix in the aerosol-generated article in any suitable manner. A skilled technician will understand the appropriate method for detecting the location of the positionable aerosol-forming matrix within the article.

[0040] As an example, the matrix may include a marker, and the apparatus may include multiple detectors configured to detect the marker. The multiple detectors may be positioned along the heating chamber. One or more detectors that receive the strongest signal from the marker may be those closest to the matrix. Therefore, this information can be used to estimate or determine the location of the locatable aerosol-forming matrix in the aerosol-generating article. Any suitable marker can be used.

[0041] As another example, the apparatus may include one or more light emitters and one or more light detectors. The one or more light emitters and one or more light detectors may be positioned around a heating chamber. The one or more light detectors may be positioned on a side of the heating chamber opposite to the one or more light detectors. After the article of manufacture is received in the heating chamber, the one or more light emitters may emit light into the heating chamber. Analyzing the light detected by the one or more light detectors can indicate the location of the locatable aerosol forming matrix. For example, each light emitter may attempt to illuminate the corresponding opposite light detector through the article of manufacture. If the locatable aerosol forming matrix is ​​located between a given emitter and its corresponding detector, less light from the given emitter may reach the corresponding detector. Therefore, analyzing the light detected at the light detectors can indicate the location of the locatable aerosol forming matrix.

[0042] Based on the preceding paragraphs, in this disclosure, an aerosol generating article is provided for use with an aerosol generating apparatus to, for example, generate aerosols. The article comprises a cavity and a positionable aerosol forming matrix, the positionable aerosol forming matrix being positionable in the cavity at at least two different locations. The article preferably includes at least one indicator configured to indicate how the position or positional change of the positionable aerosol forming matrix in the aerosol generating article affects the use of the aerosol generating article and the aerosol generating apparatus, and particularly preferably to indicate how the position or positional change of the positionable aerosol forming matrix in the aerosol generating article affects the use of the aerosol generating article and the aerosol generating apparatus.

[0043] Optionally, the aerosol-generated article may be received in the heating chamber of the aerosol-generating apparatus in at least a first orientation and a second orientation different from the first orientation.

[0044] Optionally, when the aerosol-generating article is fully received in the heating chamber in a first orientation, at least one aerosol-forming matrix of the first orientation percentage is located within the heating zone. Optionally, when the aerosol-generating article is fully received in the heating chamber in a second orientation, at least one aerosol-forming matrix of the second orientation percentage is located within the heating zone. Optionally, the first orientation percentage differs from the second orientation percentage. Optionally, the first orientation percentage differs from the second orientation percentage by at least 10%, 20%, or 30%. Advantageously, this allows the user to select the percentage of the total mass of at least one matrix within the heating zone when the article is fully received in the heating chamber by selecting the orientation in which the article is received in the heating chamber. This provides a simple way for the user to customize their experience.

[0045] Optionally, the aerosol generating article includes at least one indicator configured to indicate that the aerosol generating article can be received in the heating chamber of the aerosol generating apparatus in at least two different orientations (e.g., in a first orientation and in a second orientation).

[0046] Optionally, the aerosol generating article includes at least one indicator configured to indicate how the orientation of the aerosol generating article received in the heating chamber affects the use of the aerosol generating article in the aerosol generating system. Advantageously, this informs the user how the orientation of the article affects its use. Therefore, the user can advantageously orient the article during use in a way that will provide them with a more desirable experience.

[0047] Optionally, the aerosol generating apparatus is configured to determine the orientation of the aerosol-generated article received in the heating chamber. Optionally, the aerosol generating apparatus is configured to determine whether the aerosol-generated article is received in the heating chamber in one of a first orientation and a second orientation. Optionally, the aerosol generating apparatus is configured to control the heating profile of at least one heater based at least in part on the orientation of the aerosol-generated article received in the heating chamber or on the determination of the orientation. Advantageously, this can allow for a customized experience depending on the orientation of the article. This can be a simple way for users to customize their experience.

[0048] Users can input the orientation of the article into the device. Alternatively, the aerosol generation device can be configured to determine the orientation of the aerosol-generated article in any suitable manner. Technicians will know the appropriate method for detecting the article orientation.

[0049] As an example, the article may have a first end at one end of its length and a second end at the opposite end of its length. The first and second ends may be interchangeable, such that either end can be an open end and either end can be a distal end. The first end may include a first marker, and the second end may include a second marker. The first and second markers may be any suitable markers, such as physical or chemical markers. For example, the first marker may be a first barcode, and the second marker may be a second barcode. The device may include a detector. The detector may be configured to detect a marker at the distal end of the article, for example, after the article has been fully inserted into the heating chamber. Thus, depending on whether the first or second marker is detected, the device may be able to determine which of the first and second ends has been inserted into the heating chamber, and thus determine the orientation of the article.

[0050] Based on the preceding paragraphs, in this disclosure, an aerosol generating article is provided for use with an aerosol generating apparatus to, for example, generate aerosols. The aerosol generating article is configured to be received in the heating chamber of the aerosol generating apparatus. The article includes at least one indicator configured to indicate how the orientation of the aerosol generating article affects the use of the aerosol generating article and the aerosol generating apparatus, and preferably to indicate how the orientation of the aerosol generating article affects the use of the aerosol generating article and the aerosol generating apparatus.

[0051] As those skilled in the art will understand upon reading this disclosure, the article may include the positionable aerosol forming matrix as described above, and may be received in the heated chamber of an aerosol generating apparatus in at least a first orientation and a second orientation different from the first orientation, as described above. Other features described in relation to the orientation of the positionable matrix or article may also apply. Advantageously, combining these features can give users even more ways to customize or tailor their experience using a single article.

[0052] The following paragraphs illustrate some optional features of the aerosol-forming article. In the following text, the at least one aerosol-forming matrix may be referred to as an aerosol-forming matrix.

[0053] For example, the length of the article can be greater than the thickness of the article, for example, at least 2, 3, or 5 times the thickness of the article. Similarly, the width of the article can be greater than the thickness of the article, for example, at least 2, 3, or 5 times the thickness of the article. The length of the article can be greater than the width of the article. Advantageously, a relatively small article thickness can reduce the temperature gradient across the entire article or the entire matrix of the article during use. This may mean that a larger proportion of the matrix can reach sufficiently high temperatures to form an aerosol compared to a thicker article or matrix, without the significant risk of burning the matrix.

[0054] The terms “height” and “thickness” are used interchangeably herein. Therefore, the terms “article height” and “article thickness” are used interchangeably, as are the terms “matrix height” and “matrix thickness”.

[0055] Optionally, the product length extends in the product length direction. Optionally, the product width extends in the product width direction. Optionally, the product thickness extends in the product thickness direction. Optionally, the product length direction is perpendicular to the product width direction. Optionally, the product length direction is perpendicular to the product thickness direction. Optionally, the product width direction is perpendicular to the product thickness direction. Optionally, the product length direction, product width direction, and product thickness direction are mutually perpendicular. The product length direction can be referred to as the x-direction. The product width direction can be referred to as the y-direction. The product thickness direction can be referred to as the z-direction. The product length can extend from the upstream end to the downstream end of the product.

[0056] Optionally, the article is substantially planar in shape. Optionally, the article is substantially cuboid in shape.

[0057] The aerosol-generated article may include an upper surface, such as a substantially planar upper surface. The upper surface may be defined by a length extending in the x-direction (e.g., article length) and a width extending in the y-direction (e.g., article width). The article may include a lower surface, such as a substantially planar lower surface. The lower surface may be defined by a length extending in the x-direction (e.g., article length) and a width extending in the y-direction (e.g., article width). The upper and lower surfaces may be the outer surfaces of the article. The upper and lower surfaces may be vertically spaced apart from each other by a height defined in the z-direction, such as article thickness or article height.

[0058] At least one aerosol-forming matrix may have a matrix length, a matrix width, and a matrix thickness, or be defined by the matrix length, matrix width, and matrix thickness. The matrix length may extend in the matrix length direction. The matrix width may extend in the matrix width direction. The matrix thickness may extend in the matrix thickness direction. The matrix length direction, matrix width direction, and matrix thickness direction may be perpendicular to each other. For example, the matrix length may be greater than the matrix thickness, for example, at least 2, 3, or 5 times the matrix thickness. For example, the matrix width may be greater than the matrix thickness, for example, at least 2, 3, or 5 times the matrix thickness. The matrix length may be greater than the matrix width. Advantageously, a relatively small matrix thickness can reduce the temperature gradient across the entire matrix during use. This may mean that a larger proportion of the matrix can reach sufficiently high temperatures to form aerosols compared to a thicker matrix, without a significant risk of matrix combustion.

[0059] The matrix length can extend from the upstream end of the matrix to the downstream end of at least one matrix. The matrix length direction can be aligned with or substantially parallel to the article length direction. The matrix width direction can be aligned with or substantially parallel to the article width direction. The matrix thickness direction can be aligned with or substantially parallel to the article thickness direction.

[0060] The features describing the matrix in the two paragraphs above can be applied to the first matrix previously described. For example, features related to the relative size and orientation of the matrix length, width, and thickness can be applied to the length, width, and thickness of the first matrix previously described.

[0061] The aerosol-generating article according to this disclosure can preferably be a substantially flat article or a substantially planar article. Such articles can have a large base area relative to the volume of the article. In particular, the height of the aerosol-generating article can be less than 50% or 25% of both the length and width of the aerosol-generating article. Advantageously, a larger base area can provide a larger surface area for heating by the planar heater of the aerosol-generating apparatus. Advantageously, a smaller height can allow for a smaller temperature gradient or temperature difference across the height of the aerosol-generating article during heating. For example, in the case where the base of the aerosol-generating article is in contact with and heated by the planar heater, if the gap or height between the base and the upper surface is small, a smaller temperature difference may exist between the base and the upper surface opposite the base. Advantageously, this can allow a larger proportion of the aerosol-forming matrix of the aerosol-generating article to be heated to the temperature for releasing aerosols, while minimizing the risk of burning the hottest part of the matrix closest to the heater. Alternatively or additionally, this can reduce the time required to adequately heat the aerosol-forming matrix to release aerosols.

[0062] The aerosol generating article may have an airflow path extending through it. The aerosol generating article may have an airflow path defined as passing through it in the x / y plane from one side of the aerosol generating article to the other. Preferably, the aerosol generating article has a suction resistance (RTD) of less than 20 mmH2O, for example, less than 10 mmH2O, in the direction of the airflow path. Preferably, the aerosol generating article has an RTD of less than 20 mmH2O, for example, less than 10 mmH2O, in at least one direction in the x / y plane of the aerosol generating article. An aerosol generating article with a low-resistance airflow path allows for excellent airflow management and allows aerosols to be extracted from the aerosol generating article and directed to the user more efficiently.

[0063] Unless otherwise specified, draw resistance (RTD) is measured according to ISO 6565-2015. RTD refers to the pressure required to force air through the entire length of a component, such as an aerosol-generating article. The terms “pressure drop” or “draw resistance” for a component or article can also refer to “resistance to draw”. Such terms generally refer to measurements performed according to ISO 6565-2015, and are typically conducted at a temperature of about 22 degrees Celsius, a pressure of about 101 kPa (about 760 Torr), and a relative humidity of about 60%, at a volumetric flow rate of about 17.5 mL / s at the output or downstream end of the measured component.

[0064] An aerosol-generating article may include a substantially planar upper surface and a substantially planar lower surface. A vertical separation between the substantially planar upper and lower surfaces may define the height (e.g., z-dimension) of the aerosol-generating article. An airflow channel may be defined between the substantially planar upper and lower surfaces. The height of the aerosol-generating article may be less than 5 mm, for example, between 1.5 mm and 5 mm, between 1.5 mm and 4 mm, between 1.5 mm and 3 mm, or between 1.5 mm and 2 mm. One or both of the substantially planar upper and lower surfaces may include an aerosol-forming material. The aerosol-generating article may include an upper layer forming a substantially planar upper surface, and a lower layer forming a substantially planar lower surface. One or both of the upper and lower layers may include or be composed of an aerosol-forming material. In this case, at least one aerosol-forming matrix may include one or both of the substantially planar upper and lower layers.

In this case, at least one aerosol-forming matrix may include at least one of the first planar layer, the second planar layer, and the corrugated layer.

[0066] The use of corrugated structures in aerosol-generated articles advantageously allows for the production of aerosol-generated articles with extremely low RTD while still being rigid enough for user handling. Furthermore, the use of corrugated structures allows for the production of low-density, low-RTD aerosol-generated articles using high-speed production methods similar to those used for producing corrugated cardboard.

[0067] The aerosol generating article may include a first outer surface, a second outer surface, a cavity, and a frame. One or both of the first and second outer surfaces may be planar. The frame may be positioned between the first and second outer surfaces. The frame may at least partially define the cavity. The aerosol generating article may include an air inlet and an air outlet and an airflow passage extending through the cavity between the air inlet and the air outlet.

[0068] Preferably, at least one aerosol forming matrix is ​​positioned between the first outer surface and the second outer surface.

[0069] The frame may include a peripheral wall that at least partially defines or surrounds the cavity. The frame may also include a peripheral wall that fully defines or surrounds the cavity. Advantageously, the frame can allow aerosol-generated articles to be relatively thin while maintaining structural rigidity.

[0070] The aerosol-generating article may include a first outer layer and a second outer layer, wherein the first outer layer forms a first outer surface and the second outer layer forms a second outer surface. Optionally, at least one of the first outer layer, the second outer layer, and the frame may include or be composed of an aerosol-forming material. In this case, at least one aerosol-forming matrix may include at least one of the first outer layer, the second outer layer, and the frame.

[0071] The cavity can be substantially empty. Therefore, at least one aerosol-forming matrix can be positioned outside the cavity.

[0072] Alternatively, at least one aerosol-forming matrix may be positioned within the cavity.

[0074] The frame can be a planar frame. The frame can have a height of 50% to 95% of the height of the aerosol-generating article.

The frame can have a height of 80% to 95% of the height of the aerosol-generating article.

[0075] The frame can have a height between 1 mm and 5.5 mm. Preferably, the frame can have a height between 1 mm and 5 mm.

[0076] The frame may be made of or contain biodegradable materials. The frame may be made entirely of biodegradable materials.

[0077] The frame may be made of or contain cellulose-based materials. Cellulose-based materials may include cellulose-based material sheets. Cellulose-based materials may contain cellulose fibers. Cellulose-based materials may be paper, paperboard, or cardboard. The frame may be made of or contain plant materials such as tobacco. The frame may be made entirely of cellulose-based materials.

[0078] The frame can be a single, integral component. Alternatively, the frame can comprise two or more layers. That is, the frame can have a laminated structure.

[0079] The length of the product (e.g., x-dimension) may be between 10 mm and 100 mm, or between 10 mm and 50 mm, for example between 10 mm and 40 mm, for example between 12 mm and 30 mm, for example between 14 mm and 26 mm, for example between 16 mm and 24 mm, for example between 18 mm and 22 mm, for example about 18 mm, or about 19 mm, or about 20 mm, or about 21 mm, or about 22 mm.

[0080] The width of the product (e.g., the y-dimension) can be between 5 mm and 20 mm, for example between 8 mm and 18 mm, for example between 10 mm and 16 mm, for example between 11 mm and 15 mm, for example between 12 mm and 14 mm, for example about 13 mm.

[0081] The height of the product (e.g., z-dimension) can be between 1 mm and 10 mm, for example between 1.2 mm and 8 mm, for example between 1.4 mm and 7 mm, for example between 1.6 mm and 6 mm, for example between 1.7 mm and 5 mm, for example about 1.7 mm, or about 4.5 mm, or about 2 mm, or about 3 mm, or about 4 mm.

[0082] When viewed in a plan view, the aerosol-generating article may have a defined polygonal, quadrilateral (e.g., rectangular or square), oval, circular, or combination thereof shape. In the case where the aerosol-generating article comprises a substantially planar upper and lower surface, when viewed in a plan view, one or both of the upper and lower surfaces may have a defined polygonal, quadrilateral (e.g., rectangular or square), oval, circular, or combination thereof shape. When viewed in a plan view, the periphery of the aerosol-generating article may be formed by a plurality of straight sides, a plurality of curved sides, or a combination of straight and curved sides. In the case where the aerosol-generating article comprises a substantially planar upper and lower surface, when viewed in a plan view, the periphery of one or both of the upper and lower surfaces may have a defined polygonal, quadrilateral (e.g., rectangular or square), oval, circular, or combination thereof shape.

[0127] As used herein, the term "use process" can refer to a period of time or process in which a user applies multiple aspirations to an aerosol generation system to extract aerosols from an aerosol forming matrix. A use process can be a finite use process, i.e., a use process with a start and an end. The duration of a use process, measured in time, may be affected by the use during the use process. The duration of a use process can have a maximum duration determined by a maximum time from the start of the use process.

[0190] Figure 1 A perspective side view of an aerosol generating article 100 according to a first embodiment of the present disclosure is shown. The aerosol generating article 100 has a flat or planar upper surface 110 and a lower surface 120.

[0191] The aerosol generating article 100 includes an aerosol forming matrix (not shown). In one embodiment, the aerosol generating article 100 may consist substantially of the aerosol forming matrix. In another embodiment, the aerosol forming matrix may be one of a plurality of components of the aerosol generating article 100. The aerosol forming matrix may be encapsulated within the interior of the aerosol generating article 100. The aerosol forming matrix may at least partially define the exterior of the aerosol generating article 100; for example, one or both of the upper surface 110 and the lower surface 120 may include or be composed of the aerosol forming matrix.

[0192] A suitable aerosol-forming matrix could be homogenized tobacco.

[0193] The aerosol-generated article 100 has a length of 80 mm in the x-axis, a width of 15 mm in the y-axis, and a height (which may also be referred to as thickness) of 3.6 mm in the z-axis.

[0194] Figure 2 A perspective side view of an aerosol generating article 200 according to a second embodiment of the present disclosure is shown, which is a variation of aerosol generating article 100. Features identical to those in aerosol generating article 100 are designated by similar reference numerals but begin with the numeral 2 instead of the numeral 1. An airflow path 230 is defined to pass through the aerosol generating article 200 between an upper surface 210 and a lower surface 220. The airflow path 230 extends between opposing first ends 201 and second ends 202 of the aerosol generating article 200. The first end 201 may define a distal end of the aerosol generating article 200, and the second end 202 may define a proximal end or oral end of the aerosol generating article. The airflow path 230 may be directed toward a user's mouth to allow the user to inhale aerosols generated due to heating of the aerosol forming matrix of the aerosol generating article 200.

[0195] Figure 3 , Figure 4 and Figure 5 End view, side view and plan view of an aerosol generating article 300 according to a third embodiment of the present disclosure are shown respectively. The aerosol generating article 300 includes a planar upper layer 310, a planar lower layer 320 and an intermediate or separating layer 340 disposed between the upper layer 310 and the lower layer 320.

[0196] The upper planar layer 310 is formed of a paper sheet with a thickness of 300 micrometers. The lower planar layer 320 is formed of a paper sheet with a thickness of 300 micrometers. The middle layer 340 is a corrugated element formed of a corrugated aerosol forming matrix sheet 345. A suitable aerosol forming matrix can be homogenized tobacco. Therefore, the middle layer 340 can be formed of a corrugated homogenized tobacco material sheet 345.

[0197] Figure 6 A corrugated aerosol forming matrix sheet 345 is shown. The corrugations have a amplitude of 3 mm 346 and a wavelength of 3 mm 347. The aerosol forming matrix sheet 345 forming the intermediate layer 340 has a thickness of 150 micrometers.

[0198] The intersections 351 and 352 between the upper layer 310 and the middle layer 340, and between the lower layer 320 and the middle layer 340, include adhesives that connect the respective layers.

[0199] The aerosol-generating article 300 has a length of 80 mm in the x-axis, a width of 15 mm in the y-axis, and a height (or thickness) of 3.6 mm in the z-axis.

[0200] The corrugations of the intermediate layer 340 form a first set of longitudinally extending channels 361 defined by the upper layer 310 and the intermediate layer 340, and a second set of longitudinally extending channels 362 defined by the lower layer 320 and the intermediate layer 340. The first set of longitudinally extending channels 361 and the second set of longitudinally extending channels 362 extend across the length of the aerosol-forming matrix between the proximal end 371 and the distal end 372 of the matrix 345. The longitudinally extending channels 361, 362 define an airflow path through the matrix 345. Therefore, the airflow path crosses both sides of the aerosol-forming matrix sheet 345. The porosity of the aerosol-generated article along the airflow path is approximately 90%. This provides a very low suction resistance (RTD) of less than 5 mmH2O. In fact, the RTD is close to zero.

[0201] Aerosol forming matrix 345 can be any suitable aerosol forming matrix sheet.

[0202] During use of the aerosol generating article 300, the aerosol forming matrix 345 is heated to release volatile compounds, which are then entrained in air drawn into channels 361, 362 via distal end 372. The volatile compounds then cool and condense to form an aerosol, which can be extracted from the channels 361, 362 of the aerosol generating article 300 via proximal end 371.

[0203] Figure 7An exploded perspective view of an aerosol-generating article 400 according to a fourth embodiment of the present disclosure is shown. The aerosol-generating article 400 includes a first outer plane layer 424 forming a first outer plane surface 421, a second outer plane layer 425 forming a second outer plane surface 422, and a frame 450 positioned between the first outer plane layer 424 and the second outer plane layer 425. The second outer plane surface 422 is positioned parallel to the first outer plane surface 421. The first outer plane layer 424 is optional but present in this embodiment. The frame 450 defines and at least partially defines a cavity 430. The article also includes a rod of a generally cuboid aerosol-forming matrix 440. On the upper surface of the second outer plane layer 425, a first indicator 470, a second indicator 472, and an adhesive region 474 located therebetween are present.

[0204] The adhesive region 474 is a substantially rectangular adhesive region for adhering to the rod of the aerosol forming matrix 440. The adhesive region 474 has approximately the same width (or y-dimension) as the rod of the aerosol forming matrix 440, but has a length (or x-dimension) greater than the length of the rod of the aerosol forming matrix 440. Article 400 is supplied to the user in which the second planar outer layer 425 is in physical contact with and bonded to the frame 450, but in which the first planar outer layer 424 and the rod of the aerosol forming matrix 440 are separate. Therefore, the user can position the rod of the aerosol forming matrix 440 in its desired position in the cavity 430 on the adhesive region 474, and then optionally attach the first planar outer layer 424 to the frame 450, for example, using a suitable adhesive, to make article 400 ready for use.

[0205] In this embodiment, a first indicator 470 is printed on the outer layer 425 of the second plane and reads, "Insert end. Position the matrix closer to this end for a stronger experience." In this embodiment, a second indicator 470 is printed on the outer layer 425 of the second plane and reads, "Mouth end. Position the matrix closer to this end for a gentler experience." Therefore, the first and second indicators indicate how the position of the aerosol forming matrix 440 within the aerosol generating article 400 affects the use of the aerosol generating article 400.

[0206] In use, the experience can inherently change depending on the location of the matrix within the article. This is because the matrix's location can affect how much of the matrix is ​​positioned within the heating zone of the device used with the article when it is received in the device's heating chamber. Furthermore, as an example of how the experience can differ, if there is less matrix in the device's heating zone, less matrix may be directly heated, and more matrix may rely on conduction through the matrix to reach a sufficiently high temperature to form an aerosol. This can result in the matrix being consumed less quickly. This can lead to a gentler experience.

[0207] For example Figure 7 The experience of the article shown may be inherently altered by the position of the matrix within the article, if, for example, the article can only be received in the heating chamber of the apparatus in one orientation, or if the article can be received in the heating chamber of the apparatus in multiple orientations but these orientations do not affect how much of the matrix is ​​located within the heating zone. For Figure 7 The article shown, if it will be inserted into the device in a particular orientation, then the former option might be the case. For Figure 7 If the article shown has a fixed upstream and downstream end, but can still be received in the heating chamber in at least two orientations (the orientation shown and the orientation in which the article is rotated 180 degrees around the x-axis relative to the orientation shown), then the latter option may be the case.

[0208] As an alternative or supplement to the experience being inherently altered by the location of the matrix in the article, the device may also be able to determine or estimate the location of the matrix 440, or the user may input the location of the matrix 440 into the device, and the device may then select heating profiles for one or more heaters of the device based at least in part on the location of the matrix 440 to alter the experience.

[0209] The first outer planar layer 424 and the second outer planar layer 425 are made of cigarette paper with a thickness of 35 micrometers. The second outer planar layer 425 is in physical contact with and bonded to the frame 450. The first outer planar layer 424 is optional and can be placed by the user, for example, in contact with and bonded to the frame 450 after the user has positioned the rod of the aerosol forming matrix 440 in the cavity 430 (as will be discussed in more detail later). The first outer planar layer 424 then covers the first upper end of the cavity 430 and forms a first cavity end wall. The second outer planar layer 425 covers the second lower end of the cavity 430 and forms a second cavity end wall, which is opposite to the first cavity end wall. That is, the frame 450, the first outer planar layer 424, and the second outer planar layer 425 together define the boundary of the cavity 430. In the absence of the first outer planar layer 424, Figure 7 In the embodiment shown, the cavity will be an open cavity, undefined on the side where the outer layer 424 of the first plane is located.

[0210] Frame 450 has a hollow cuboid shape and is made of cardboard. Frame 450 defines an orifice extending through the height (also referred to as thickness) of frame 450, and the orifice at least partially forms a cavity 430 of aerosol generating article 400. Frame 450 includes a peripheral wall 451 defining the cavity 430. Peripheral wall 451 includes a front wall 413 and a rear wall 414. More specifically, peripheral wall 451 is defined by an inner transverse surface 452 and an outer transverse surface 453 of frame 450. The inner transverse surface 452 of peripheral wall 451 at least partially defines the periphery of cavity 430. The outer transverse surface 453 of peripheral wall 451 at least partially defines the periphery of aerosol generating article 400. Peripheral wall 451 has a radial thickness of approximately 5 mm, measured between the inner transverse surface 452 and the outer transverse surface 453 of frame 450.

[0211] Air inlet 411 and air outlet 412 are defined by and extend through the peripheral wall 451 of frame 450. More specifically, air inlet 411 extends through front wall 413, and air outlet 412 extends through rear wall 414. Air inlet 411 and air outlet 412 have an equivalent diameter of 5 mm. An airflow passage extends through cavity 430 between air inlet 411 and air outlet 412. Figures 9 to 11 As shown, the aerosol forming matrix 440 is positioned within the cavity 430. The aerosol forming matrix 440 comprises a homogenized aerosol generating material in the form of tobacco material and has an aerosol forming agent content of 5% by weight (dry weight). As shown, the aerosol forming matrix 440 fills a portion of the volume of the cavity 430.

[0212] On the outer surface of the peripheral wall 451 of the frame 450 (which lies in the xz plane), near the end with the first air vent.

[0213] The aerosol-generating article 400 has a cuboid shape and a height (or thickness) of 8 mm in the z-axis (measured between the first planar outer surface 421 and the second planar outer surface 422), a width of 40 mm in the y-axis, and a length of 60 mm in the x-axis. The frame 450 has a height (or thickness) of 7.93 mm in the z-axis, a width of 40 mm in the y-axis, and a length of 60 mm in the x-axis. The cavity 430 has a height (or thickness) of 7.93 mm in the z-axis, a width of 30 mm in the y-axis, and a length of 50 mm in the x-axis.

[0214] Figure 8 The article 400 is shown after the first outer plane layer 424 and the second outer plane layer 425 have been bonded to the frame 450 and the article 400 is ready for use.

[0215] Figure 9 The image shows an article 400 after the second planar outer layer 425 has been bonded to the lower surface of the frame 450, and the matrix 440 has been positioned on and adhered to the adhesive layer 474. However, the first planar outer layer 424 has not yet been bonded to the upper surface of the frame 450. This is optional. At this point, the first planar outer layer 424 can be discarded or bonded to the upper surface of the frame 450. In this embodiment, the rods of the aerosol forming matrix 440 are positioned closer to the first indicator 470 than the second indicator 472.

[0216] Figure 10 and Figure 11 The transverse and longitudinal cross-sectional views of the aerosol-generated article 400 are shown when the cavity 430 contains the aerosol-forming matrix 440.

[0217] Figure 12 A fifth embodiment of the aerosol generating article 500 according to this disclosure is shown. Features identical to those of aerosol generating article 400 are designated by similar reference numerals, but begin with the numeral 5 instead of the numeral 4. The aerosol generating article 500 differs from aerosol generating article 400 in that the aerosol forming matrix is ​​in the form of a sheet of aerosol generating material 540 (particularly a corrugated sheet of homogenized tobacco material), and there is no first indicator 470 and a second indicator 472, nor is there an adhesive region 474. The aerosol generating article 500 also differs from aerosol generating article 400 in that a third indicator 580 and a fourth indicator 582 are present on the peripheral wall of the frame 550. Figure 13 and Figure 14 It shows Figure 12 The corresponding transverse and lateral cross-sectional views of the aerosol-generated product 500.

[0218] The corrugated homogenized tobacco material sheet 540 includes multiple parallel corrugations having a plurality of substantially parallel peaks 543 and valleys 544. The multiple parallel corrugations are defined by a corrugation profile, as shown in... Figure 13 The waveform shown is sinusoidal. Multiple parallel ripples have a ripple wavelength of approximately 4.6 mm. As shown by the peaks 543 and troughs 544 that coincide with the first cavity end wall 531 and the second cavity end wall 532, respectively, the ripple amplitude is approximately the same as the height (or thickness) of the cavity 430.

[0219] Multiple parallel corrugations form multiple channels 545 between the aerosol generating material sheet 540 and the first cavity end wall 531, and multiple channels 546 between the aerosol generating material sheet 540 and the second cavity end wall 532. The multiple channels 545 and 546 extend in the longitudinal direction of the aerosol generating article 500 and form at least a portion of an airflow passage extending between the air inlet 511 and the air outlet 512.

[0220] From a structural point of view, article 500 is essentially symmetrical. This means that either end of article 500 can act as the upstream end, while the other end acts as the downstream end. Therefore, depending on the orientation of article 500 when it is received in the heating chamber of the device, the air inlet and air outlet can be interchanged.

[0221] The frame 550 includes a third indicator 580 and a fourth indicator 582. The third indicator 580 is positioned near a first longitudinal end of the article 500, and therefore near one of the air inlet and air outlet. The fourth indicator 582 is positioned near a second opposing longitudinal end of the article 500, and therefore near the other of the air inlet and air outlet.

[0222] The third indicator 580 includes the statement "Insert this end into the device for a shorter, more intense experience" and a third indicator barcode. The fourth indicator 582 includes the statement "Insert this end into the device for a longer, less intense experience" and a fourth indicator barcode different from the third indicator barcode.

[0223] The user can choose which end of the article 500 to insert into the heating chamber of the device. The device may include one or more barcode scanners capable of scanning a barcode at the distal end of the article 500 when it is received in the heating chamber, and thus determining the orientation of the article 500 as it is inserted into the device. The device can then control the heating profile of at least one heater of the device to influence the experience during use. For example, in this case, if the user inserts the end with the third indicator 580 into the heating chamber first, the device will scan the third indicator barcode and determine that the user wants a shorter, more intense experience. Thus, the operating temperature of at least one heater of the device can be set higher than if the device had scanned a fourth barcode and determined that the user wanted a longer, less intense experience. At a higher operating temperature, more aerosol can be formed more quickly during use. This can provide the user with a more intense experience. In addition, the aerosol-forming matrix is ​​consumed more quickly. This can result in a shorter user experience.

[0224] During use of each of the aerosol generating articles 400 and 500, the aerosol forming matrix 440 and 540 are heated to release volatile compounds, which are then entrained in air drawn into chambers 430 and 530 through air inlets 411 and 511. The volatile compounds are then cooled and condensed to form an aerosol, which can be extracted from the aerosol generating articles 400 and 500 through air outlets 412 and 512.

[0225] Figure 15 and Figure 16 An aerosol generating apparatus 6000 configured for use with an aerosol generating article 600 is shown, and Figure 17 An aerosol generating apparatus 6000 is shown in conjunction with an aerosol generating article 600.

[0226] In this embodiment, article 600 is similar to Figure 7 Article 400. However, article 600 can be any of the previously described articles 100, 200, 300, 400, 500. Article 600 includes a rod of aerosol forming matrix 640, which is similar to... Figure 7 The product 400 is an aerosol forming matrix 440 rod.

[0227] Device 6000 is an elongated aerosol generating device extending between a proximal end 6001 and a distal end 6002. Device 6000 includes a battery 6010, a controller 6020, and at least one heater 6030 located within a housing 6040. The controller 6020 controls the power supply from the battery 6010 to the at least one heater 6030. A cavity 6050, also referred to as a heating chamber 6050, is defined in device 6000, having an opening 6051 defined in the proximal end 6001 of the device. The opening 6051 is rectangular in shape and sized to accommodate a cross-section of an aerosol generating article 600. Heating chamber 6050 includes an upper planar surface 6052 and a lower planar surface 6053. At least one heater 6030 may form on or be located near the lower planar surface 6053 to heat the lower surface of the aerosol generating article 600 inserted into heating chamber 6050. At least one heater 6030 defines a heating zone 6100 within a heating chamber 6050. The heating zone 6100 is entirely located within the heating chamber 6050. The upstream and downstream boundaries of the heating zone 6100, indicated by dashed lines, coincide with the upstream and downstream boundaries of the at least one heater 6030. The device 6000 also includes a component 6102 located at the base of the heating chamber 6050. The component 6102 has a stop surface at its rightmost end. The airflow path is configured to allow air to flow from outside the device 6000 into the heating chamber 6050.

[0228] Figure 17 The image shows the bonding of the aerosol generating article 600. Figure 15 The apparatus 6000 has virtually no tolerance between the outer surface of the aerosol generating article 600 and the inner surface of the heating chamber 6050. Therefore, there is a tight fit between the aerosol generating article 600 and the apparatus 6000.

[0229] When the article 600 is inserted into the heating chamber 6050 and the upstream end of the article 600 abuts the stop surface of the component 6102, the article 600 is fully received in the device 6000, and the stop surface prevents the article 600 from being further inserted into the heating chamber 6050. In this position, the upstream end of the matrix 640 is within 10 mm of the upstream end of the heater 6030 (which coincides with the upstream end of the heating zone), and approximately 70% of the total mass of the aerosol forming matrix 640 is located within the heating zone 6100.

[0230] Since the RTD of the aerosol generating article 600 is negligible, the RTD of the system formed by the combination of the aerosol generating article 600 and the aerosol generating device 6000 is controlled by the airflow path confined within the device.

[0231] The device 6000 is operable when a user inserts the aerosol generating article 600 into the heating chamber 6050. At least one heater 6030 heats the lower surface of the aerosol generating article 600, and thus the aerosol forming matrix 640 of the aerosol generating article 600. The volatile components of the aerosol forming matrix 640 evaporate and condense to form an aerosol. The user draws in the aerosol by suctioning from the proximal end 601 of the aerosol generating article 600. Once the volatile components of the aerosol generating matrix 640 of the aerosol generating article 600 have been exhausted, the aerosol generating article is removed from the heating chamber 6050 of the device 600 and discarded. The aerosol generating article 600 can be any of the previously described aerosol generating articles 100, 200, 300, 400, 500 or any other aerosol generating article of this disclosure.

[0232] although Figure 17 The illustration shows a portion of the aerosol generating article 600 extending outside the aerosol generating apparatus 6000, but in other embodiments, the entire aerosol generating article may be completely enclosed within the aerosol generating apparatus. For example, Figure 18 It shows Figure 17 Alternative embodiments of the embodiments, wherein similar features are referred to by the same reference numerals, but with an apostrophe ' added. For Figure 18 In an alternative embodiment, the aerosol generating article 600' is entirely enclosed within the aerosol generating apparatus 6000', and the heater 6030' is shorter, such that 20% to 80% of the total mass of the matrix 640' remains within the heating zone.

[0233] In what might appear to be Figures 15 to 17In some of the same embodiments shown, at least one heater 6030, 6030' may heat portions of the aerosol forming matrix 640, 640' at different times. For example, at least one heater 6030, 6030' may include three structurally identical heaters: a first heater positioned along the upstream third of at least one heater 6030, 6030'; a second heater positioned along the middle third of at least one heater 6030, 6030'; and a third heater positioned along the downstream third of at least one heater 6030, 6030'. In use, when the device 6000, 6000' is activated, only one of the three heaters (e.g., the first heater) may be activated first. Then, later during use, the second heater may be activated. At this time, the first heater may be deactivated or remain activated. Then, later during use, the third heater may be activated. At this time, the first and second heaters may be deactivated or remain activated. The advantage of this staggered start-up of the heaters is that it reduces the risk that the relatively large portions of the matrix 640, 640' will reach sufficiently high temperatures to simultaneously form aerosols (which could mean that most of the flavor of the matrix 640, 640' is exhausted in just a few puffs).
