Description

Technical Field

[0001] This disclosure relates to an aerosol generating apparatus for use with an aerosol generating article, and an aerosol generating system including the aerosol generating apparatus. Background Technology

[0002] Aerosol-generating articles, such as those in which an aerosol-generating matrix containing a tobacco matrix is ​​heated rather than burned, are known in the art. In heated aerosol-generating articles, aerosols are generated by heating the aerosol-generating matrix.

[0003] One type of aerosol generation system is an electrically operated smoking system. Known handheld electrically operated smoking systems typically include an aerosol generation device comprising a rechargeable battery, control electronics, and an electric heater for heating an aerosol-generating article specifically designed for use with the aerosol generation device. In some instances, the aerosol-generating article comprises an aerosol-forming matrix, such as a tobacco stick or tobacco rod, and when the aerosol-generating article is inserted into the aerosol generation device, a heater contained within the aerosol generation device is inserted into or positioned around the aerosol-forming matrix.

[0004] A heating element can be incorporated into an aerosol generating apparatus to generate inhalable vapor. Such an apparatus heats the aerosol generating matrix contained within an aerosol generating article without burning the aerosol generating matrix. In doing so, the aerosol generating matrix can generate an aerosol, which can then be delivered to a user.

[0005] Such aerosol-generating articles can be in the form of conventional cigarettes. In this case, the aerosol-generating matrix can be wrapped in cigarette paper. This method may be suitable when the aerosol-generating matrix comprises strands or strips of material (e.g., strands of cast tobacco or strands of shredded tobacco).

[0006] However, this method may not be effective in preserving other forms of aerosol generating matrix, such as particulate or powdered aerosol generating matrices. Such aerosol generating articles may be susceptible to leakage of the aerosol generating matrix during their storage, handling, and use. Leakage of the aerosol generating matrix can be exacerbated by high ambient temperatures and humidity. Loss of the aerosol generating matrix through leakage can adversely reduce the lifespan of aerosol generating articles that include the aerosol generating matrix. Leakage of the aerosol generating matrix can negatively impact the overall performance of the aerosol generating article. For example, leakage of the aerosol generating matrix can negatively affect the consistency of the inhalable aerosols generated by an aerosol generating system that includes the aerosol generating article.

[0007] To provide an aerosol generating article in which the loss or leakage of the aerosol generating matrix is ​​reduced or prevented even when the aerosol generating article is heated to the temperature required to generate aerosols from the aerosol generating matrix, an aerosol generating article comprising a container may be provided. Such an aerosol generating article may be able to retain different forms of the aerosol generating matrix, such as granular or powdered aerosol generating matrix. Such aerosol generating articles comprising containers can be easily handled and operated by the consumer when used with a suitable aerosol generating apparatus. However, prior art aerosol generating apparatuses may not be suitable for heating aerosol generating articles comprising containers. For example, inserting a heating element into an aerosol generating article comprising a container may adversely cause leakage of the aerosol generating matrix from the container. Additionally, existing heaters configured to externally heat the aerosol generating article may not provide effective heating sufficient to generate a consistent aerosol from an aerosol generating article comprising a container. Summary of the Invention

[0008] There is a need for an aerosol generating apparatus suitable for use with an aerosol generating article, such as an aerosol generating article including a container.

[0009] There is a need for an aerosol generating apparatus that can provide more reliable heating of the aerosol generating article. There is also a need for an aerosol generating apparatus that can provide more consistent aerosol generation from the aerosol generating article used in conjunction with the aerosol generating apparatus.

[0010] According to a first aspect of this disclosure, an aerosol generating apparatus is provided for use with an aerosol generating article. The aerosol generating apparatus may include a first portion including a first housing. The first housing may include a recess for receiving the aerosol generating article. The aerosol generating apparatus may include a second portion including a second housing and a heater assembly configured to heat the aerosol generating article when received in the recess. The aerosol generating apparatus may include a connecting mechanism connecting the first housing to the second housing and configured to allow relative movement between the first housing and the second housing. The aerosol generating apparatus may include a clamping mechanism configured to allow relative movement between the recess and at least a portion of the heater assembly in response to relative movement between the first housing and the second housing.

[0011] Advantageously, a clamping mechanism configured to allow relative movement between the recess and at least a portion of the heater assembly allows the heater assembly to move toward the recess and thus toward the aerosol-generating article during use. Advantageously, the distance between the heater assembly and the aerosol-generating article can therefore be reduced during use. For example, the contact between the heater assembly and the aerosol-generating article can be improved. As a result, more reliable heating of the aerosol-generating article and more consistent aerosol generation can be achieved.

[0012] Providing a connection mechanism to connect the first housing to the second housing prevents the user from separating the first housing from the second housing. Conveniently, this prevents either the first or second part of the device from being removed from the device and potentially misplaced by the user.

[0013] Advantageously, the clamping mechanism, configured to allow relative movement between the recess and at least a portion of the heater assembly in response to relative movement between the first and second housings, facilitates the insertion of the aerosol-generating article into the device. Advantageously, this allows the aerosol-generating article to remain in the same position within the aerosol-generating apparatus each time it is loaded. For example, since the clamping mechanism is actuated in response to relative movement between the first and second housings, the force that can be applied to the aerosol-generating article by the heater assembly during loading can be consistent each time, as this force is applied by the clamping mechanism, not by the user during insertion. Therefore, the distance between the heater assembly and the recess can be the same each time the aerosol-generating article is inserted. Advantageously, this improves the consistency of heating and aerosol generation, and thus enables more consistent aerosol generation.

[0014] Preferably, the clamping mechanism is configured to cause relative movement between the recess and at least a portion of the heater assembly in response to relative movement between the first housing and the second housing.

[0015] The clamping mechanism can be configured to allow relative movement between the recess and the heater assembly. In particular, the heater assembly may include a heating element, and the clamping mechanism can be configured to allow relative movement between the recess and the heating element.

[0016] The clamping mechanism can push the heater assembly toward the recess in response to relative movement between the first housing and the second housing. Alternatively or additionally, the clamping mechanism can push the recess toward the heater assembly in response to relative movement between the first housing and the second housing.

[0017] Preferably, the clamping mechanism pushes the heater assembly toward the aerosol generating article positioned in the recess.

[0018] The clamping mechanism may not contact the first part of the aerosol generating device. Preferably, the clamping mechanism does not contact the first housing.

[0019] The connecting mechanism can be a separate component from the clamping mechanism.

[0020] The connecting mechanism can be configured to allow relative movement between the first housing and the second housing in a first plane. The clamping mechanism can be configured to allow relative movement between the recess and at least a portion of the heater assembly in a second plane. Preferably, the first plane is perpendicular to the second plane. For example, in response to relative movement between the first housing and the second housing in the longitudinal direction of the aerosol generating apparatus, the clamping mechanism can be configured to move the heater assembly relative to the recess in a direction orthogonal to the longitudinal direction of the aerosol generating apparatus. Preferably, the clamping mechanism pushes the heater assembly toward the aerosol generating article positioned in the recess, wherein the heater assembly and the surface of the aerosol generating article configured to contact the heater assembly are substantially coplanar. Preferably, the clamping mechanism is configured to apply a force to the aerosol generating article received in the recess, the force being substantially uniform on the surface of the aerosol generating article configured to contact the heater assembly. Advantageously, this improves the heating uniformity of the entire aerosol generating article and thus enables more consistent aerosol generation.

[0021] The clamping mechanism can be configured to allow relative movement of at least a portion of the recess and the heater assembly between a clamped position and an unclamped position. In the second plane, the distance between at least a portion of the heater assembly and the base of the recess can be greater in the unclamped position than in the clamped position.

[0022] In the clamping position, the opening of the recess can be substantially closed by at least a portion of the heater assembly.

[0023] Advantageously, providing an opening in the recess that is substantially closed by at least a portion of the heater assembly can reduce the amount of air and generated aerosol that can leak out of the recess through the opening (in addition to through the air outlet), which can improve the amount of aerosol delivered to the user.

[0024] The clamping mechanism may include an elastic element configured to allow relative movement between the recess and at least a portion of the heater assembly.

[0025] The clamping mechanism may include an elastic element configured to allow at least a portion of the heater assembly to move relative to the recess. For example, the elastic element may be configured to elastically push at least a portion of the heater assembly toward the recess. The elastic element may be positioned between an inner wall of the second housing and the heater assembly, and may be configured to allow at least a portion of the heater assembly to move relative to the second housing.

[0026] The elastic element can be configured to allow relative movement between the recess and the heater assembly.

[0027] The elastic element can be configured to allow relative movement between the recess and the heater assembly.

[0028] The elastic element may include a spring. For example, the second portion may include a spring configured to allow at least a portion of the heater assembly to move relative to the recess. The elastic element may include one, two, three, or four springs. Preferably, the elastic element is configured to apply a force to the heater assembly such that the heater assembly applies the force to the aerosol generating article positioned within the cavity, such that the force applied to the aerosol generating article is substantially uniform on the surface of the aerosol generating article configured to contact the heater assembly. Advantageously, this improves the heating uniformity of the entire aerosol generating article and thus enables more consistent aerosol generation.

[0029] The spring can be positioned between the inner wall of the second housing and the heater assembly, and can be configured to allow at least a portion of the heater assembly to move relative to the second housing.

[0030] The spring can be a leaf spring.

[0031] The spring may include a conductive material. Any other type of clamping mechanism may include a conductive material. Advantageously, providing a clamping mechanism that includes a conductive material allows the clamping mechanism to supply power to the heater assembly.

[0032] The aerosol generating device may include a hinge disposed between and connected to the spring and the heater assembly. Preferably, the hinge is a rigid hinge. The aerosol generating device may include one, two, three, or four hinges, each disposed between and connected to the corresponding spring and the heater assembly.

[0033] The combination of hinges and springs can provide a bistable mechanism. Advantageously, this allows the clamping mechanism to function as a locking mechanism to hold the heater assembly in the clamped position.

[0034] The clamping mechanism may include a first tilting element connected to the second housing and a second tilting element connected to the heater assembly. The first and second tilting elements may include corresponding inclined surfaces configured to slide relative to each other to allow relative movement between the recess and at least a portion of the heater assembly in response to relative movement between the first and second housings.

[0035] The first tilting element can be a wedge-shaped element. The second tilting element can also be a wedge-shaped element.

[0036] Preferably, the first tilting element may comprise a deformable elastic material.

[0037] The heater assembly may include a roller configured to allow relative movement between a recess and at least a portion of the heater assembly. A first portion may include a roller recess configured to receive the roller.

[0038] The aerosol generating apparatus may include a resetting element for guiding the heater assembly away from the recess. Advantageously, the resetting element allows the user to more easily move the first housing relative to the second housing.

[0039] The aerosol generating apparatus may include a limiting element configured to restrict movement of the heater assembly relative to the second housing.

[0040] The limiting element may include a limiting spring for limiting movement of the heater assembly. The limiting element may include an anchor for limiting movement of the heater assembly. The limiting element may include a stop positioned in the first portion for limiting relative movement between the heater assembly and the recess. Advantageously, the limiting element prevents misalignment of the heater assembly and the recess when the first housing moves relative to the second housing.

[0041] The aerosol generating device may include a mouthpiece. A first part may include the mouthpiece. The mouthpiece may be integral with the first housing. The mouthpiece may be removable. Advantageously, providing a removable mouthpiece allows it to be removed for cleaning, or replaced without replacing the entire device.

[0042] Preferably, the connecting mechanism includes a sliding mechanism that connects the first portion to the second portion and is configured to allow relative movement between the first and second housings in a closed position. The connecting mechanism can be a sliding mechanism. The sliding mechanism can connect the first housing to the second housing. The sliding mechanism can be configured to allow translation of the second housing relative to the first housing between an open position and a closed position.

[0043] The sliding mechanism provides a simple and robust connection, facilitating one-handed handling of the aerosol generating device and operation of the relative movement between the first and second housings. The sliding mechanism is also relatively simple to manufacture, offering a straightforward and robust connection.

[0044] The sliding mechanism may include a clamping mechanism, such as a connecting spring. In response to relative movement between the first and second housings in the longitudinal direction of the aerosol generating apparatus, the connecting spring may be configured to move the recess relative to the heater assembly in a direction orthogonal to the longitudinal direction of the aerosol generating apparatus.

[0045] The connecting mechanism can be configured to allow relative movement between a first housing and a second housing between a closed position and an open position, wherein in the closed position the recess is closed by the first portion; and in the open position the recess is opened for insertion of an aerosol-generating article.

[0046] In the closed position, the recess can be at least partially closed by the heater assembly. Preferably, in the closed position, the recess can be enclosed by the heater assembly.

[0047] For example, in the closed position, the recess may be sealed by the first portion. Preferably, in the closed position, the recess may be sealed by the heater assembly.

[0048] The heater assembly may include a heating element. The heater assembly may include a resistance heating element. During use, current may be supplied to the resistance heating element to generate heat through resistance heating.

[0049] Suitable materials for forming resistance heating elements include, but are not limited to: semiconductors (such as doped ceramics), electrically "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, and superalloys based on nickel, iron, cobalt, stainless steel, Timetal®, and iron-manganese-aluminum based alloys.

[0050] The resistance heating element may include one or more stamped portions of a resistive material (such as stainless steel). Alternatively, at least one resistance heating element may include a heating wire or filament, such as a Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wire.

[0051] The resistance heating element may include at least one electrically insulating substrate, wherein the resistance heating element is disposed on the at least one electrically insulating substrate.

[0052] At least one electrically insulating substrate may comprise any suitable material. For example, the electrically insulating substrate may comprise one or more of paper, glass, ceramics, anodized metals, coated metals, and polyimide. Ceramics may comprise mica, alumina (Al2O3), or zirconium oxide (ZrO2). The electrically insulating substrate may have a thermal conductivity of less than or equal to about 40 W / m Kelvin, preferably less than or equal to about 20 W / m Kelvin, and ideally less than or equal to about 2 W / m Kelvin.

[0053] A resistance heating element may include a heating element comprising a rigid electrically insulating substrate having one or more conductive tracks or lines disposed on its surface. In use, an electric current can pass through one or more conductive tracks to heat the resistance heating element and an aerosol-generating matrix received within a recess.

[0054] The heater assembly may include an induction heating element. During use, the induction heating element inductively heats at least one sensor material to heat an aerosol-generating article received within a recess. The at least one sensor material may form part of an aerosol-generating apparatus. The induction heating element may include at least one sensor coil configured to generate an alternating magnetic field. During use, the alternating magnetic field is configured to inductively heat the sensor material.

[0055] The induction heating element can be connected to a power source configured to supply a high-frequency oscillating current to the inductor coil. As used herein, a high-frequency oscillating current means an oscillating current with a frequency between approximately 500 kHz and approximately 30 MHz. The inductor coil can be arranged to generate an alternating magnetic field when receiving the high-frequency oscillating current from the power source. The inductor coil can be arranged to generate an alternating magnetic field within a recess.

[0056] A heater assembly including an induction heating device can be advantageously used in combination with an aerosol-generating article including a sensor element.

[0057] The receptor element may include any suitable receptor element.

[0058] In some embodiments, the heater assembly may include at least one resistance heating element and at least one induction heating element. In some embodiments, the heater assembly may include a combination of resistance heating elements and induction heating elements.

[0059] The heater assembly may include a heating element and a support element for supporting the heating element.

[0060] Preferably, the support element may comprise a heat-resistant and non-conductive material. The support element may comprise a heat-resistant polymer. For example, the support element may comprise polyetheretherketone (PEEK). The support element may be made of PEEK. The support element may comprise ceramic. For example, the support element may comprise alumina. In another example, the support element may comprise zirconium oxide.

[0061] The heater assembly may include a sealing member to seal the aerosol-generated article within the recess during heating. The heating element may be mounted on the sealing member. A support element may include the sealing member.

[0062] The heating element can be mounted on the surface of the sealing member facing the recess.

[0063] Preferably, the heater assembly may include a heating element and a support element, wherein the heating element is resiliently mounted on the support element such that the heating element can be resiliently pushed into the recess. For example, the heater assembly may include a resilient member positioned between the support element and the heating element to allow relative movement between the support element and the heating element. Preferably, the heating element may be resiliently mounted on a sealing member via the resilient member such that the heating element is resiliently pushed into the recess.

[0064] Preferably, the sealing member is elastically mounted on the second housing by means of an elastic element, such that the heating element is elastically pushed into the recess.

[0065] Advantageously, providing a heating element that is elastically pushed into the recess can improve the contact between the heating element and the aerosol-generating article during heating, thus improving aerosol generation.

[0066] The sealing member can be configured to deform at least a portion of the aerosol-generating article to seal the aerosol-generating article within the recess.

[0067] The heating element can protrude from the sealing member toward the recess to allow the heating element to directly contact the aerosol-generated article.

[0068] The heating element can be integrated with the sealing component.

[0069] The heating element can be fixedly attached to the sealing component.

[0070] The sealing member may include a sealing frame having a peripheral structure surrounding the orifice, wherein the sealing frame is configured to seal the periphery of the recess. A heating element may extend across the orifice. The sealing frame may be configured to provide mechanical support to the heating element.

[0071] The support element may also include a fixing member for securing the heater to the sealing member. The fixing member may be movable relative to the sealing member. For example, the fixing member may be movable relative to the sealing frame such that at least a portion of the fixing member can enter an orifice to push the heating element toward the recess. The fixing member may comprise a heat-resistant and non-conductive material. For example, the fixing member may comprise polyetheretherketone (PEEK). The fixing member may be made of PEEK. The fixing member may be configured to forcefully push the heating element toward the recess, said force being substantially uniform on the surface of the heating element configured to contact the aerosol-generating article. When the heating element contacts the aerosol-generating article, the heating element may be substantially coplanar with the aerosol-generating article. Advantageously, the force applied to the surface of the aerosol-generating article may be substantially uniform to provide uniform heating of the aerosol-generating article. Advantageously, this improves the heating consistency of the entire aerosol-generating article and thus enables more consistent aerosol generation.

[0072] The recess may include one or more air inlets and one or more air outlets, as well as an airflow path defined between the one or more air inlets and the one or more air outlets.

[0073] At least one air inlet allows air to enter the recess and approach the aerosol-generated article received within the recess. At least one air inlet may be located at the upstream end of the recess. At least one air outlet allows the aerosol to exit the recess for delivery to the user. At least one air outlet may be located at the downstream end of the recess.

[0074] The shortest line connecting any one of the one or more air inlets to any one of the one or more aerosol outlets is not parallel to either the width or the length of the recess.

[0075] Advantageously, providing the shortest line, which is not parallel to each of the width and length of the recess, connecting any one of the one or more air inlets to any one of the one or more air outlets, can increase the length of the airflow path through the recess. Therefore, the contact between the airflow through the aerosol generating device and the aerosol generating matrix of the aerosol generating article received in the recess can be increased.

[0076] Advantageously, providing the shortest line, not parallel to each of the width and length of the recess, connecting any one of the one or more air inlets to any one of the one or more air outlets, can increase the release of active ingredients (such as nicotine and flavoring, or both) from the aerosol-generating matrix of the aerosol-generating article received within the recess into the aerosol. Advantageously, aerosol generation and delivery can be improved throughout the user experience. In particular, advantageously, aerosol generation and delivery can be improved at the end of the user experience.

[0077] It should be understood that the feature "the shortest line connecting any one of the one or more air inlets to any one of the one or more air outlets is not parallel to either the width or the length of the recess" means that there is no air inlet such that the shortest line connecting any one of the air inlets to any one of the aerosol outlets is parallel to the width of the recess, and there is no air inlet such that the shortest line connecting any one of the air inlets to any one of the aerosol outlets is parallel to the length of the recess. Therefore, this also means that the shortest line connecting any one of the one or more aerosol outlets to any one of the one or more aerosol inlets is not parallel to either the width or the length of the recess. In other words, it is possible that there is no line parallel to the width of the recess that intersects both the inlet and outlet of the recess, and it is possible that there is no line parallel to the length of the recess that intersects both the inlet and outlet of the recess. In other words, there may not be a straight line parallel to the width of the recess connecting the entrance and exit of the recess, and there may not be a straight line parallel to the length of the recess connecting the entrance and exit of the recess.

[0078] The shortest line connecting any one of the one or more air inlets to any one of the one or more air outlets of the recess may not be parallel to the longitudinal axis of one or both of the recess and the aerosol generating device. In other words, the one or more air inlets and one or more air outlets of the recess may be offset relative to the longitudinal axis of one or both of the recess and the aerosol generating device.

[0079] The aerosol generating apparatus may include a sensor for detecting airflow through the apparatus. The sensor may be an airflow sensor. Preferably, the sensor is a pressure sensor for detecting airflow through the apparatus.

[0080] The sensor can be configured to detect suction. The sensor allows for control of the heater assembly's heating based on the detection of airflow through the device. Advantageously, the temperature of the heater assembly can be adjusted based on the sensor's measurements. For example, the sensor can detect when negative pressure is applied to the device's air outlet, such as during user suction. The magnitude and frequency of user suction can be monitored by a controller, which can control the electrical force supplied to the heater assembly in response to sensor measurements.

[0081] A sealed air passage can be provided between the first and second housings. The sensor can measure pressure through this sealed air passage.

[0082] The connection mechanism may include an airflow sensor. The second part of the aerosol generating apparatus may include a sensor. Advantageously, providing a second part of the aerosol generating apparatus that includes a sensor allows for the placement of electrical components associated with the sensor within the second part of the aerosol generating apparatus. Advantageously, this can reduce the number of electrical connections required between the first and second parts of the apparatus, or it can eliminate the need for electrical connections between the first and second parts of the apparatus. For example, if the power supply for powering the heater assembly, sensor, and control electronics is also included in the second part, this can allow the apparatus to be configured without electrical connections or interfaces between the first and second parts. Advantageously, this simplifies the connection between the first and second housings, simplifies the construction of the apparatus, and improves the reliability of the electrical system by requiring fewer interfaces. Advantageously, electrical interfaces may not be required in the connection mechanism.

[0083] The first part of the aerosol generating device may include a sensor.

[0084] Providing a sensor within the first section allows the sensor to also function as a contact sensor, configured to detect the electrical connection between the first and second sections. Advantageously, the sensor acting as a contact sensor may be able to detect whether the aerosol generating device is in the off position.

[0085] Advantageously, the first portion of the aerosol generating device, including the sensor and the recess, improves the seal of the sensor relative to the position in the first portion where the sensor performs measurements. Advantageously, this improves the accuracy of the measurements performed by the sensor.

[0086] In addition to one or more air inlets in the recess, the aerosol generating apparatus may also include a device air inlet for allowing air to enter the aerosol generating apparatus. The device air inlet of the aerosol generating apparatus may be in fluid communication with the air inlet in the recess. The device air inlet may be located on a first device housing portion or a second device housing portion.

[0087] In addition to one or more air outlets in the recess, the aerosol generating apparatus may also include a device air outlet for allowing aerosols to exit the aerosol generating apparatus. The aerosol generating apparatus may include a mouthpiece located at a downstream end of the aerosol generating apparatus. The mouthpiece may be configured as part of a first housing. The mouthpiece may be removably attached to the first housing. The device air outlet may be disposed in the mouthpiece. This device air outlet may be in fluid communication with the air outlet in the recess.

[0088] The sensor can be configured to measure pressure changes between the air inlet of the device and one or more air inlets in the recess.

[0089] Advantageously, configuring a pressure sensor to measure pressure changes between the device's air inlet and one or more air inlets in the recess can reduce the risk of condensation along the airflow path measured by the pressure sensor. Advantageously, configuring a pressure sensor to measure pressure changes between the device's air inlet and one or more air inlets in the recess can reduce the complexity of the pressure sensor arrangement.

[0090] The pressure sensor can be configured to measure the pressure change between the air inlet of the device and one or more air outlets in the recess.

[0091] Advantageously, configuring a pressure sensor to measure the pressure change between the air inlet of the device and one or more air outlets of the recess can improve the reliability of the measurements performed by the pressure sensor.

[0092] The recess may have a length of at least 10 mm. For example, the recess may have a length of at least 12 mm, at least 14 mm, at least 16 mm, or at least 18 mm.

[0093] The recess may have a length not exceeding 30 mm. For example, the recess may have a length not exceeding 28 mm, 25 mm, 20 mm, or 18 mm.

[0094] The recess may have a length between about 10 mm and about 30 mm, between about 12 mm and about 28 mm, between about 14 mm and about 25 mm, or between about 20 mm and about 16 mm.

[0095] The recess may have a length of approximately 14 mm. The recess may have a length of approximately 16 mm. The recess may have a length of approximately 18 mm.

[0096] Preferably, the aerosol generating device can be portable. The aerosol generating device is preferably a handheld device. The aerosol generating device can be part of a handheld aerosol generating system. Preferably, the aerosol generating device is configured to be held in hand during use.

[0097] According to a second aspect of the present invention, an aerosol generation system is provided. The aerosol generation system may include an aerosol generation apparatus and an aerosol generation article.

[0098] Aerosol-generated products can be any type of aerosol-generated product.

[0099] Preferably, the aerosol generation system can be portable. The aerosol generation system can be a handheld aerosol generation system. Preferably, the aerosol generation system is configured to be held in hand during use.

[0100] The aerosol-generating article may include a container comprising a first wall and a second wall. The first wall and the second wall may together define a matrix compartment. The aerosol-generating matrix may be disposed within the matrix compartment.

[0101] The first wall may contain a different material than the second wall. The first wall may contain a flexible cellulose-based material. The second wall may have higher stiffness than the first wall. Alternatively, the first wall may have higher stiffness than the second wall.

[0102] The heater assembly can be configured to contact the second wall of the aerosol-generated article.

[0103] At least a portion of the first wall may be porous. The first wall may comprise a nonwoven material. As used herein with reference to the invention, the term "cellulose-based material" refers to a material made of cellulose or a derivative of cellulose.

[0104] The first wall can include any cellulosic material. The first wall can also include nonwoven materials.

[0105] As used herein with reference to this invention, the term "nonwoven" refers to a manufactured sheet, web, or wadding of oriented or randomly oriented fibers bonded together by friction, and / or cohesion and / or adhesion, excluding products formed by weaving, braiding, tufting, stitching (with the incorporation of bonding yarns or filaments), or by wet felting (whether or not additionally needle-punched). The fibers may be of natural or synthetic origin.

[0106] The first wall may include molded paper material.

[0107] The second wall may be non-porous. The second wall may comprise a substantially planar material. The second wall may comprise a paper material.

[0108] The aerosol-generating matrix may contain at least one alkaloid.

[0109] As used herein with reference to this invention, the term "alkaloid compound" is used to describe any of a class of naturally occurring organic compounds containing one or more basic nitrogen atoms. Typically, alkaloids contain at least one nitrogen atom in an amine-type structure. This or other nitrogen atom in the alkaloid compound molecule can function as a base in acid-base reactions. In most alkaloid compounds, one or more of the nitrogen atoms are part of a cyclic system, such as a heterocycle.

[0200] Figure 13 A schematic cross-sectional view is shown of an aerosol generating article for use with the aerosol generating apparatus of the present invention. Detailed Implementation

[0201] Figure 1A A cross-sectional view of the aerosol generating apparatus 100 according to the invention in the open position is shown. The aerosol generating apparatus 100 is intended for use with aerosol generating articles ( Figure 1A (Not shown in the image) used together. The device 100 includes a first portion 101 and a second portion 102. The first portion 101 includes a first housing 103, and the second portion 102 includes a second housing 104. A connecting mechanism 112 connects the first housing 103 to the second housing 104 and is configured to allow relative movement between a closed position and an open position. The first housing 103 includes a recess 110 for receiving an aerosol-generated article. In the closed position, the recess 110 is closed by the second portion 102 of the aerosol-generating device 100. In the open position, the recess 110 is open for insertion of the aerosol-generated article.

[0202] like Figure 1A As shown, the connecting mechanism 112 is a sliding mechanism 114 that connects the first housing 103 to the second housing 104 and is configured to allow relative movement between the first housing 103 and the second housing 104 between a closed position and an open position. In particular, the sliding mechanism 114 is configured to allow translation of the first housing 103 relative to the second housing 104 between an open position and a closed position.

[0203] The second part 102 includes a heater assembly 106 configured to heat the aerosol-generating article when it is received in the recess 110. In the closed position ( Figure 1B As shown in the diagram, heater assembly 106 is opposite to recess 110 and closes the recess.

[0204] The clamping mechanism 115 is positioned in the second portion 102 and configured to allow relative movement between the recess 110 and at least a portion of the heater assembly 106 in response to relative movement between the first housing 103 and the second housing 104. Figure 1A and 1BAs shown, the clamping mechanism 115 may include an elastic element, such as a spring 117, positioned between the heater assembly 106 and the inner wall of the second housing 104. The spring is configured to extend and elastically push the heater assembly 106 toward the recess 110 as the first portion 101, particularly the first housing 103, moves relative to the second portion 102, particularly the second housing 104. In other words, the clamping mechanism 115 is configured to allow relative movement between the recess 110 and at least a portion of the heater assembly 106 between a clamped position and an unclamped position. The distance between the heater assembly 106 and the base of the recess 110 is greater in the unclamped position than in the clamped position. When the first housing 103 and the second housing 104 are moved by the user from an open position to a closed position, the clamping mechanism 115 moves the heater assembly 106 toward the recess 110 from the unclamped position to the clamped position. Furthermore, the clamping mechanism 115 is configured to move the heater assembly 106 away from the recess when the first housing 103 and the second housing 104 are moved by the user from a closed position to an open position.

[0205] Device 100 includes a device air inlet (not shown), and recess 110 includes one or more air inlets and one or more air outlets. Figure 1A (Not shown). The airflow path is defined between one or more air inlets and one or more air outlets. The device air inlets are in fluid communication with one or more air inlets. The device 100 also includes a device air outlet (not shown) in fluid communication with one or more air outlets of the recess.

[0206] The mouthpiece 105 is located at the downstream end of the aerosol generating device 100, and the mouthpiece 105 includes the device air outlet. Figure 1A and 1B The mouthpiece 105 shown is integral with the first housing 103. However, it should be understood that, alternatively, the mouthpiece 105 may be removably attached to the first portion 101.

[0207] The second part 102 includes a power supply 108 and a controller 109 electrically connected to the heater assembly 106. The power supply 108 is configured to supply power to the heater assembly 106, while the controller 109 is configured to control the power supply to the heater assembly 106.

[0208] The second part 102 includes a pressure sensor 107 for detecting the airflow through the aerosol generating device 100. However, it should be understood that the pressure sensor may alternatively be located in the first part 101. A power supply 108 and a controller 109 are also electrically connected to the sensor 107.

[0209] Figure 1BA cross-sectional view of the aerosol generating apparatus 100 according to the invention in the closed position is shown, wherein the aerosol generating apparatus has received the aerosol generating article 950 within the recess 110. The aerosol generating apparatus and the aerosol generating article received in the recess may be collectively referred to as an aerosol generating system.

[0210] In the closed position, heater assembly 106 is opposite to recess 110 and closes the recess. Heater assembly 106 is positioned to contact aerosol generating article 950.

[0211] exist Figure 1B In the closed position shown, the aerosol generating apparatus 100 is configured to heat the aerosol to generate article 950.

[0212] Before and between using the aerosol generating device 100, the user can keep the device in the closed position. To use the device, the user moves the first housing 103 and the second housing 104 from the closed position to... Figure 1A The recess 110 is shown in the open position. In the closed position, the recess 110 is closed by the second portion 102. In the open position, the recess is open for insertion of the aerosol generating article. The user can then insert the aerosol generating article 950 into the recess 110 (see [reference]). Figure 1B The user then moves the first housing 103 and the second housing 104 from the open position. Figure 1B The diagram shows the closed position, in which the recess 110 is closed by the second portion 102. When the user moves the first housing relative to the second housing, as the spring 117 extends from the compressed position (when the device is open) to the extended position, the clamping mechanism 115 allows the heater assembly 106 to move toward the recess 110, such that the heater assembly is pushed toward the recess 110. Specifically, the heater assembly 106 is pushed toward the aerosol generating article 950 positioned in the recess 110. The clamping mechanism compresses the aerosol generating article 950 into the recess 110 via the heater assembly 106. The aerosol generating device is then ready for use.

[0213] In use, the controller 109 supplies power from the power source 108 to the heating element of the heater assembly 106, causing current to flow through the heating element and raising its temperature. Heat is transferred to the aerosol forming article 950, causing the aerosol forming matrix of the aerosol forming article 950 to heat up, and volatile compounds to vaporize from the aerosol forming matrix.

[0214] In use Figure 1BDuring the process of using the apparatus and article shown, a user inhales through mouthpiece 105. During each user inhale, air is drawn through mouthpiece 105 of the aerosol generating apparatus 100 toward the user's mouth. During inhalation, air is drawn from outside the aerosol generating apparatus through the apparatus air inlet, through the recessed air inlet, and into the recess 110. In the recess 110, the air comes into contact with the aerosol forming matrix of the aerosol generating article 950. The air passes through the aerosol generating article 950 to the recessed air outlet. As the air passes through the aerosol forming matrix, volatile compounds generated by heating the aerosol forming matrix are entrained in the air. As the air continues to flow through the apparatus from the recessed air outlet to the apparatus air outlet, the volatile compounds cool to form an aerosol, which is then inhaled by the user of the apparatus.

[0215] Figure 2 The closed position is shown. Figure 1B A cross-sectional view of a portion of an aerosol generating device. (See diagram below.) Figure 2 As shown, when the device is in the closed position, the heater assembly 106 closes the recess. The heater assembly 106 includes a heating element 120 and a support element 122 configured to provide mechanical support to the heating element. Figure 2 In the example shown, the support element 122 includes a sealing member 124 for sealing the aerosol-generated article within the recess 110 during heating. The support element 122 also includes a fixing member 126 for securing the heating element 120 to the sealing member 124.

[0216] The heating element 120 is mounted on the sealing member 124 facing the recess 110, such that during heating, the surface of the heating element 120 will face or contact the aerosol-generated article. Figure 2 In the example shown, the heating element 120 is fixedly attached to the sealing member 124. However, it should be understood that in other examples, the heating element 120 may be integral with the sealing member 124. The heating element 120 protrudes from the sealing member 124 toward the recess 110 to allow the heating element 120 to directly contact the aerosol-generated article when the article is received in the recess 110. The sealing member 124 is made of polyetheretherketone (PEEK).

[0217] Figure 2 The device is shown in the clamping position, so the spring 117 of the clamping mechanism extends to push the heating element 120 toward the recess 110, such that when the aerosol-generating article is received in the recess 110, the heating element contacts the article.

[0218] The recess 110 includes a recess air inlet 111 and a recess air outlet 113, wherein an airflow path is defined therebetween, such that in use, the airflow travels directly through the aerosol-generated article received in the recess 110.

[0219] Figure 3 A perspective view of a heating element 220, a heating element 220 mounted on a sealing member 224, and a heater assembly 206 for an aerosol generating apparatus according to a second embodiment of the present disclosure is shown. The heater assembly 206 includes the heating element 220, the sealing member 224, and the fixing member 226. The heater assembly 206 is an alternative example of a heater assembly suitable for the aerosol generating apparatus of the present disclosure. Instead of heater assembly 106, heater assembly 206 may be included in apparatus 100.

[0220] Heating element 220 is a resistance heating element; however, it should be understood that, alternatively or additionally, an induction heating element may be used.

[0221] The sealing member 224 includes a sealing frame 225 configured to seal the periphery of the recess. The sealing frame 225 has a peripheral structure surrounding the orifice. Figure 3 As shown, heating element 220 extends across the orifice. Sealing frame 225 is configured to provide mechanical support to heating element 220.

[0222] The heater assembly 206 also includes a retaining member 226. The retaining member 226 is mounted to the sealing member 224. The retaining member 224 is mounted to an internal portion of the second housing of the device. The clamping mechanism includes two springs 227 to allow the heater assembly 206 to move relative to a recess in the device in response to relative movement between the first housing and the second housing.

[0223] Figure 4A and 4B A schematic cross-sectional view of a portion of an aerosol generating apparatus 300 according to a third embodiment of the present disclosure is shown. Figure 4A and 4B The aerosol generating device 300 is substantially the same as the aerosol generating device 100 and operates in substantially the same manner, unless otherwise stated below.

[0224] exist Figure 4A and 4B In the illustrated device, the heater assembly 306 is resiliently mounted to an internal portion of the second housing 104 via a clamping mechanism 330 comprising two leaf springs 335. The device may alternatively include one, three, or four leaf springs. The leaf springs 335 are configured to respond to the second housing portion 304 relative to the first housing 303 from... Figure 4A The opening position shown is moved to Figure 4B The closed position shown allows the heater assembly to... Figure 4A The unclamped position shown is the same as Figure 4BThe device moves between the clamping positions shown. In the open position, the heater assembly 306 closes the recess 310, such that, in use, the aerosol-generated article received in the recess 310 can be heated by the heating element 320 of the heater assembly 306. In the clamping position, the leaf spring 335 elastically deforms to apply a force to the heater assembly 306 toward the base of the recess 310. Therefore, the heater assembly 306 applies a compressive force to the aerosol-generated article received in the device.

[0225] The heating element 320 is elastically mounted to the support element 322 via an elastic member 340. In this example, the elastic member 340 is a leaf spring. However, it should be understood that the aerosol generating device 300 can be implemented with a heating element 320 fixedly mounted to the support element 322 without an elastic member.

[0226] The aerosol generating apparatus also includes a stop 350 positioned in a first part of the apparatus to limit relative movement between the heater assembly 306 and the recess 310. When the apparatus moves from the open position to the closed position, upon reaching the closed position, the heater assembly 306, particularly the support element 322, abuts the stop 350, thus maintaining the longitudinal position of the heater assembly 306 above the recess 110.

[0227] Advantageously, the leaf spring 335 can be made of a conductive material to supply electricity from the power source of the aerosol generating device to the heater assembly 306 to heat the heating element 320.

[0228] Figure 5A and 5B A schematic cross-sectional view of a portion of an aerosol generating apparatus 400 according to a fourth embodiment of the present disclosure is shown. Figure 5A and 5B The aerosol generating apparatus 400 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the third example share the same reference numerals.

[0229] The clamping mechanism 430 of the aerosol generating device 400 includes two flexible leaf springs 435 and two rigid hinges 436 connecting the leaf springs 435 to the support element 322. When the second housing 304 moves relative to the first housing 303, the heater assembly 306 is guided toward the recess 310 by the hinges 436 on the flexible leaf springs 435. When the device reaches the closed, clamped position, the support element 322 abuts against the stop 350, preventing further movement of the heater assembly 306 in the longitudinal direction of the device, while the support element 322 and the heating element 320 are pushed toward the recess 310 by the hinges 436.

[0230] The aerosol generating device 400 also includes a limiting spring 438 for restricting movement of the heater assembly 306 relative to the second housing 304. In the open position, the limiting spring 438 extends ( Figure 5A ), and in the closed position, the limiting spring 438 is compressed ( Figure 5B ).

[0231] Figure 6A and 6B A schematic cross-sectional view of a portion of an aerosol generating apparatus 500 according to a fifth embodiment of the present disclosure is shown. Figure 6A and 6B The aerosol generating apparatus 500 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the third and fourth examples share the same reference numerals.

[0232] The aerosol generating device 500 includes a clamping mechanism 530. The clamping mechanism 530 includes a first inclined wedge element 533 as part of a support element 522. The clamping mechanism 530 also includes a second inclined wedge element 534 connected to a second housing 304 via a leaf spring 535. Alternatively, the second wedge element may be elastically deformable and directly connected to the second housing 304. A limiting spring 438 limits movement of the heater assembly 506 relative to the second housing 304.

[0233] The first inclined wedge element 533 and the second inclined wedge element 534 include corresponding inclined surfaces configured to slide relative to each other to allow relative movement between the heater assembly 506 and the recess 310 in response to relative movement between the first housing and the second housing 304.

[0234] Aerosol generating device 500 Figure 6A The image shows the unclamped position, and... Figure 6B The image shows the device in the clamping position.

[0235] Figure 7A and 7B A schematic cross-sectional view of a portion of an aerosol generating apparatus according to a sixth embodiment of the present disclosure is shown. Figure 7A and 7B The aerosol generating apparatus 600 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the fifth example share the same reference numerals.

[0236] The aerosol generating device 600 includes an anchor 660 that restricts movement of the heater assembly 506. The anchor is configured to allow a first end of the support element 522 to move in the longitudinal direction of the device 600, while corresponding inclined wedge elements 533, 534 slide relative to each other, thereby allowing the support element 522 to tilt in the open position.

[0237] When the device is closed, the support element 522 is blocked by the anchor 660 adjacent to the stop 650, which maintains the longitudinal position of the heater assembly 506 relative to the recess 310.

[0238] In the unclamped position, the first wedge 533 is adjacent to the second wedge 534 in the longitudinal direction of the aerosol generating device 600. In the clamped position, the first inclined wedge element 533 and the second inclined wedge elements 533 and 534 are longitudinally aligned, but displaced in a direction orthogonal to the longitudinal direction to push the heating element 320 into the recess 310.

[0239] Figure 8A and 8B A schematic cross-sectional view of a portion of an aerosol generating apparatus 700 according to a seventh embodiment of the present disclosure is shown. Figure 8A and 8B The aerosol generating apparatus 700 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the sixth example share the same reference numerals.

[0240] The clamping mechanism 730 includes a spring 717 connected between the second housing 704 and the support element 722. When the second housing 704 moves to the closed position relative to the first housing 703, the spring elastically pushes the heater assembly 706 toward the recess 310.

[0241] Roller 760 allows relative movement between heater assembly 706 and recess 310. First portion 701 includes roller recess 750 configured to receive roller 760 in a clamping position.

[0242] Figure 9A and 9B A schematic cross-sectional view of a portion of an aerosol generating apparatus according to an eighth embodiment of the present disclosure is shown. Figure 9A and 9B The aerosol generating apparatus 800 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the fourth and seventh examples share the same reference numerals.

[0243] The aerosol generating device 800 includes a clamping mechanism 717 and a heater assembly 306.

[0244] The aerosol generating device 800 includes a latch 820, which is located in the second portion and attached to the inner surface of the second housing 704. The latch 820 engages with the support member 322 in the unclamped position. In this position, the heater assembly 306 is raised relative to the recess 310.

[0245] The first part of the aerosol generating device 800 includes a stop 810. The stop 810 engages with the latch 820 in the clamping position.

[0246] In the unclamped position, the heater assembly is vertically secured by latch 820. When the user moves the first housing 702 toward the closed position, latch 820 engages with stop 810 and releases support member 322. As support member 322 is released from latch 820, spring 717 elastically pushes heater assembly 306 toward recess 310.

[0247] The aerosol generating apparatus also includes a reset element 815 having an inclined contact surface for guiding the heater assembly 306 away from the recess 310 and pushing the heater assembly 306 back to the unclamped position, which involves compressing the spring 717 until the support element 322 re-engages with the latch 820.

[0248] Figure 10A and 10B A schematic cross-sectional view of a portion of an aerosol generating apparatus 850 according to a ninth embodiment of the present disclosure is shown. Figure 10A and 10B The aerosol generating apparatus 850 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the eighth example share the same reference numerals.

[0249] The clamping mechanism includes a spring 717, which is configured in the unclamped position ( Figure 10A The extension state and clamping position in ) Figure 10B The heater assembly 306 moves between the compressed state and the unclamped position. Figure 10C The displacement profile 864 of the sliding mechanism shown is controlled.

[0250] In this example, the first housing 703 is connected to the second housing 704 via a sliding mechanism. When the first housing 703 moves relative to the second housing 740 by the user sliding the first housing 703 in the longitudinal direction of the device, the displacement profile 864 of the sliding mechanism causes the heater assembly 306 to move relative to the recess 310 in a direction orthogonal to the longitudinal direction of the device. Therefore, when the first housing 703 moves toward the second housing 740 by the user sliding the first housing, the spring 717 is compressed.

[0251] Figure 11A and 11B A schematic cross-sectional view of a portion of an aerosol generating apparatus 880 according to a tenth example of the present disclosure is shown. Figure 11A and 11B The aerosol generating apparatus 880 shown is substantially the same as the aerosol generating apparatus 100 and operates in substantially the same manner, unless otherwise stated below. Features identical to those in the ninth example share the same reference numerals.

[0252] exist Figure 11A and 11B In the example shown, the heater assembly 306 is fixedly attached to the second housing 704. Therefore, the heater assembly does not move relative to the housing 704.

[0253] In this example, the first housing 703 is connected to the second housing 704 via a sliding mechanism. The displacement profile 884 of the sliding mechanism is... Figure 11C As shown in the diagram. The sliding mechanism includes a clamping mechanism. The clamping mechanism includes a spring 887.

[0254] When the first housing 703 moves relative to the second housing 740 by the user sliding the first housing 703 in the longitudinal direction of the device, the displacement profile 884 of the sliding mechanism causes the first housing 703 to move orthogonally to the longitudinal direction of the device relative to the second housing 704. Therefore, when the first housing 703 moves relative to the second housing 740 by the user sliding the first housing 703 in the longitudinal direction of the device, the displacement profile 884 of the sliding mechanism causes the heater assembly 306 to move relative to the recess 310 in a direction orthogonal to the longitudinal direction of the device. For example, in the open, unclamped position, the spring 887 extends, and the heater assembly 306 is offset relative to the recess 310 in both the longitudinal direction and the direction orthogonal to the longitudinal direction. When the first housing 703 moves toward the second housing 740 in the longitudinal direction, the spring 887 is compressed to move the second housing 704 in a direction orthogonal to the longitudinal direction, and thus move the heater assembly 306. This movement continues until the heater assembly 306 is aligned with the recess 310, at which point the device is in the closed, clamped position. In the closed clamping position, the spring 887 extends due to the displacement profile 884 of the sliding mechanism 884, thus closing the heater assembly 306 recess 310.

[0255] The displacement profile 884 of the sliding mechanism also includes a reset element, such as Figure 11C The inclined plane shown in the figure. The inclined plane allows the first housing 703 to slide away from the clamped or unclamped position relative to the second housing 704 by converting the force applied by the user in the longitudinal direction into a force for compressing the spring 887, in which the spring 887 extends.

[0256] Figure 12 A schematic perspective view of a recess in an aerosol generating apparatus 900 according to the eleventh embodiment of the present disclosure is shown. The aerosol generating apparatus 900 includes the features described above. Figure 1A and 1B All features of the aerosol generating device 100 are described.

[0257] The recess 910 includes an air inlet 911 and an air outlet 912. The width 921, length 922, and depth 923 of the recess 910 are shown.

[0258] The shortest line 924 connecting the air inlet 911 and the air outlet 912 is not parallel to the width 921 of the recess 910. The shortest line 924 connecting the air inlet 911 and the aerosol outlet 912 is not parallel to the length 922 of the recess 910.

[0259] Air inlet 911 is at a first depth, and aerosol outlet 912 is at a second depth. The first depth and the second depth are different.

[0260] The recess 904 includes a bottom wall 905 and a side wall. The side wall includes an upstream side wall 906 and a downstream side wall 907.

[0261] An air inlet 911 is located in the upstream sidewall 906. An air outlet 912 is located in the downstream sidewall 907.

[0262] The distance between air outlet 912 and bottom wall 905 is less than the distance between air inlet 911 and bottom wall 905. In an alternative embodiment, the distance between air outlet and bottom wall may be the same as or greater than the distance between air inlet and bottom wall.

[0263] Figure 13 The diagram illustrates an aerosol generating article 950 for use with the aerosol generating apparatus of the present invention. The aerosol generating article 950 includes a container 960. The container 960 includes a first wall 961 and a second wall 962, which together define a matrix compartment 963. An aerosol generating matrix 964 is disposed within the matrix compartment.

[0264] exist Figure 13 In the example shown, the first wall 961 is formed of a nonwoven cotton material. The first wall 961 comprises between 85% and 90% by weight of cellulose, between 7% and 16% by weight of hemicellulose, and between 1% and 3% by weight of lignin. The first wall 961 is porous.

[0265] The second wall 962 comprises paper. The second wall 962 has a basis weight of approximately 35 gsm. The second wall is non-porous.

[0266] The second wall 962 is basically planar. The second wall 962 has higher rigidity than the first wall 961. In this way, the first wall 961 can be substantially formed into a bag shape closed by the second wall 962.

[0267] Aerosol generating matrix 964 is disposed in matrix compartment 963. Aerosol generating matrix 964 comprises homogenized tobacco material particles and an aerosol forming agent. The aerosol forming agent comprises glycerol. Matrix compartment 963 contains approximately 150 mg of aerosol generating matrix 964.
