Description

[0001] The present invention relates to an aerosol-generating article configured for receiving a flavor capsule.

[0002] Aerosol-generating articles in which an aerosol-generating matrix, such as a tobacco-containing matrix, is heated rather than burned, are known in the art. Typically, in such heated aerosol-generating articles, aerosols are generated by transferring heat from a heat source to a physically separated aerosol-generating matrix or material, which may be positioned in contact with, within, around, or downstream of the heat source. During use of the aerosol-generating article, volatile compounds are released from the aerosol-generating matrix through heat transfer from the heat source and entrained in the air drawn through the aerosol-generating article. As the released compounds cool, they condense to form an aerosol.

[0003] Various aerosol generating articles for consuming heated aerosol generating articles are known in the art. Such devices include, for example, electrically heated aerosol generating articles, wherein aerosols are generated by transferring heat from one or more electrically heated elements of the aerosol generating article to an aerosol generating matrix of the heated aerosol generating article. For example, electrically heated aerosol generating articles comprising internal resistance heater blades adapted to be inserted into the aerosol generating matrix have been proposed. Alternatively, inductively heated aerosol generating articles include sensor elements disposed within the aerosol generating matrix, which can be heated by an alternating magnetic field provided by the aerosol generating article.

[0004] Heated aerosol generating articles are typically cigarette-shaped and include multiple elements or rods. For example, such articles typically include: a matrix rod comprising an aerosol generating matrix, a tubular rod downstream of the matrix rod, and a mouthpiece filter section at the mouth end of the article. The tubular rod has an inner cavity or hollow core defining an airflow path. It is known to have two tubular rods: a first tubular rod and a separate second tubular rod, the first tubular rod serving as a spacer between the matrix rod and other components of the aerosol generating article, and the second tubular rod serving as an air cooler to cool air as it passes through the aerosol generating article to facilitate aerosol formation. The second tubular rod is generally adjacent to the first tubular rod.

[0005] Consumers typically prefer flavored aerosol-generated products for reasons including: enhanced taste, masking of tobacco irritation, smooth perception, personal preference, novelty, and social factors. Manufacturers offer alternative methods for users to obtain flavor. One option is crushable flavor capsules, which users can insert into the filter section of an RRP HNB using readily available tools.

[0006] However, using such tools with existing specifications disrupts airflow management and alters suction resistance and filtration efficiency. Therefore, a new configuration needs to be developed that adapts to flavor capsule insertion without requiring the user to damage or modify filter segments for insertion.

[0007] An insertion tool is known to first form a hole in a filter segment of an aerosol-generating article, thereby allowing the capsule to be inserted in a second process step.

[0008] The aim is to provide an aerosol-generating article with an enhanced consumer experience by offering a rod configuration that allows for the insertion of flavor capsules while preventing damage to the filter segments during the flavor capsule insertion process.

[0009] According to embodiments of the present invention, an aerosol generating article configured for receiving a flavor capsule is provided. The aerosol generating article can be configured to receive a flavor capsule and may include an upstream end and a downstream end. The upstream end may be configured to connect to a holder for the aerosol generating article. The aerosol generating article may include a cooling section, wherein the cooling section may include a first hollow tube and a second hollow tube. The cooling section may be located at the downstream end. The first hollow tube may be configured to provide a through-hole for inserting the flavor capsule. The second hollow tube may be disposed upstream of the first hollow tube and may be configured to receive the flavor capsule. The inner diameter of the second hollow tube may be larger than the inner diameter of the first hollow tube. The aerosol generating article may include a matrix portion containing an aerosol forming matrix, wherein the cooling section may be disposed downstream of the matrix portion.

[0010] The term "aerosol-generating article" is used herein to refer to an article in which an inhalable aerosol is generated from an aerosol-generating matrix and delivered to a consumer. As used herein, the term "aerosol-generating matrix" refers to a matrix from which aerosols may be formed or generated. For example, an aerosol-generating matrix may be able to release volatile compounds to generate aerosols when heated. Alternatively, an aerosol-generating matrix may include particles that can be entrained in an airflow to generate aerosols.

[0011] As used herein, the term "cooling section" refers to a designated portion or area within an aerosol-generating article where the aerosol is cooled. This section is specifically designed to regulate the flow of the aerosol to reduce its temperature, thereby optimizing its performance, improving user comfort, or achieving desired operating conditions.

[0012] As used herein, the term "hollow tube" refers to a generally hollow, elongated element that defines a lumen or airflow passage along its longitudinal axis. Specifically, the term "tube" will be used with reference to a tubular element having a substantially cylindrical cross-section and defining at least one airflow conduit establishing uninterrupted fluid communication. However, it should be understood that alternative geometries (e.g., alternative cross-sectional shapes) of the tubular element may be possible. The first and second hollow tubes may be separate, independent components of the aerosol-generating article.

[0013] A "through-hole" refers to a passage formed within the aerosol-generating article, specifically within the first hollow tube of the cooling section. The through-hole is configured to allow insertion of a flavor capsule without damaging other components of the aerosol-generating article. It functions as a conduit through which the flavor capsule can be introduced into the aerosol-generating article via a capsule insertion tool. The "through-hole" can be configured at the downstream end of the aerosol-generating article, wherein the first hollow tube serves as the user's mouth end.

[0014] As used herein, the terms “upstream” and “downstream” describe the relative position of an element or portion of an aerosol-generating article with respect to the direction in which aerosols are transported through the aerosol-generating article during use.

[0015] As used in this article, the terms “upstream” and “downstream” can also be referred to as “proximal” and “distal”.

[0016] According to an embodiment of the present invention, an aerosol generating article configured for receiving a flavor capsule is provided. The aerosol generating article is configured for receiving a flavor capsule and includes an upstream end and a downstream end. The upstream end is configured to connect to a holder for the aerosol generating article. The aerosol generating article includes a cooling section, wherein the cooling section includes a first hollow tube and a second hollow tube. The cooling section is located at the downstream end. The first hollow tube is configured to provide a through-hole for inserting the flavor capsule. The second hollow tube is disposed upstream of the first hollow tube and is configured to receive the flavor capsule. The inner diameter of the second hollow tube is larger than the inner diameter of the first hollow tube. The aerosol generating article includes a matrix portion containing an aerosol forming matrix, wherein the cooling section is disposed downstream of the matrix portion.

[0017] An aerosol-generating article is provided that can enhance the consumer experience by providing a rod configuration that allows for the insertion of a flavor capsule while preventing damage to the filter segment during the flavor capsule insertion process.

[0018] The inner diameter of the second hollow tube can be similar to or larger than the outer diameter of the insertable flavor capsule, so that the insertable flavor capsule can remain in the second hollow tube after the flavor capsule is inserted.

[0019] The advantage of having an inner diameter of the second hollow tube similar to or larger than the outer diameter of the insertable flavor capsule is that it allows the flavor capsule to remain securely positioned within the second hollow tube after insertion. This ensures that the flavor capsule remains in place during use, preventing displacement or movement within the aerosol-generating article. By maintaining the position of the flavor capsule, the user can consistently experience the desired flavor enhancement throughout the entire duration of use without worrying about the capsule shifting or becoming displaced. Furthermore, this configuration enhances user convenience, as the user can easily insert the flavor capsule into the aerosol-generating article and trust that it will remain in place without the need for additional securing mechanisms.

[0020] The aerosol generating article may also include a main filter, wherein the main filter may be arranged downstream of the matrix portion and preferably directly adjacent to the matrix portion, and wherein the main filter may be arranged downstream of the cooling section.

[0021] Incorporating a main filter into the aerosol-generating article enhances the filtration process, removing particulate matter and potentially harmful components from the aerosol, thus improving aerosol purity and making the inhalation experience safer. The presence of the main filter contributes to a smoother and more pleasant inhalation experience by filtering out impurities and reducing irritation. Structurally, the main filter provides support for the device, maintaining its integrity during use. Furthermore, the placement of the main filter relative to the matrix section and cooling zone optimizes airflow management within the device, ensuring efficient aerosol generation and delivery to the user, allowing for flavor capsule insertion while preventing damage to the main filter during flavor capsule insertion.

[0022] Aerosol generating articles may also include a front bar, which may be positioned upstream of the matrix portion. Including a front bar in the aerosol generating article provides structural support. By being positioned upstream of the matrix portion, the front bar helps to hold the matrix in place and prevent any movement or displacement during use. This ensures stable aerosol generation and aerosol delivery to the user. Additionally, the front bar contributes to the overall stability and durability of the device, thereby extending its lifespan and improving reliability.

[0023] The matrix portion may include a sensor. As used herein, the term "sensor" refers to a material that can convert electromagnetic energy into heat. When located within a fluctuating electromagnetic field, eddy currents induced in the sensor cause heating of the sensor.

[0024] The receptor is arranged in thermal contact with the aerosol-generating matrix. Therefore, when the receptor heats up, the aerosol-generating matrix is ​​heated by the receptor to generate aerosols. The receptor can be arranged in direct physical contact with the aerosol-generating matrix.

[0025] The receptor can be a slender receptor.

[0026] As used in this article, the term "slender" is used to describe a component of an aerosol-generated article whose length is greater than its width and thickness.

[0027] The elongated receptors can be arranged substantially longitudinally within the aerosol-generating matrix. That is, the longitudinal axis of the elongated receptors can be approximately parallel to the longitudinal axis of the aerosol-generating matrix. For example, the longitudinal axis of the elongated receptors can be within ±10 degrees of the longitudinal axis of the aerosol-generating matrix. The elongated receptors can be located at the radial center within the aerosol-generating matrix and extend along the longitudinal axis of the aerosol-generating matrix.

[0028] The receptor can extend from the downstream end of the aerosol generating matrix toward the upstream end of the aerosol generating matrix.

[0029] The receptor can extend from the upstream end of the aerosol generating matrix toward the downstream end of the aerosol generating matrix.

[0030] The receptor can extend from the upstream end to the downstream end of the aerosol-generating matrix. In other words, the receptor can extend along the entire length of the aerosol-generating matrix.

[0031] The length of the receptor can be substantially the same as the length of the aerosol-generating matrix.

[0032] The receptors can extend partially along the length of the aerosol-generating matrix.

[0033] The receptor can be spaced apart from the downstream end of the aerosol-generating matrix.

[0034] The receptor can be spaced apart from the upstream end of the aerosol-generating matrix.

[0035] The receptor can be spaced apart from both the downstream and upstream ends of the aerosol-generating matrix.

[0036] The length of the receptor can be less than the length of the aerosol-generating matrix.

[0037] The receptor can be completely enclosed within the aerosol-generating matrix. In other words, the aerosol-generating matrix can completely surround the receptor.

[0038] Receptors can take the form of needles, strips, bands, or blades.

[0039] The receptor may have a length of at least about 5 mm, at least about 6 mm, or at least about 8 mm. The receptor may have a length of less than or equal to about 15 mm, less than or equal to about 12 mm, or less than or equal to about 10 mm.

[0040] The receptor can have a length between approximately 5 mm and approximately 15 mm, between approximately 5 mm and approximately 12 mm, or between approximately 5 mm and approximately 10 mm.

[0041] The receptor can have a length between approximately 6 mm and approximately 15 mm, between approximately 6 mm and approximately 12 mm, or between approximately 6 mm and approximately 10 mm.

[0042] The receptor can have a length between approximately 8 mm and approximately 15 mm, between approximately 8 mm and approximately 12 mm, or between approximately 8 mm and approximately 10 mm.

[0043] The receptor can have a width of at least about 1 millimeter.

[0044] The receptor can have a width of less than or equal to about 5 millimeters.

[0045] The receptor can have a width between about 1 mm and about 5 mm.

[0046] The receptor may have a thickness of at least about 0.01 mm or at least about 0.5 mm.

[0047] The receptor can have a thickness of less than or equal to about 2 millimeters, less than or equal to about 500 micrometers, or less than or equal to about 100 micrometers.

[0048] The receptor can have a thickness between about 10 micrometers and about 2 millimeters, between about 10 micrometers and about 500 micrometers, or between about 10 micrometers and about 100 micrometers.

[0049] The receptor can have a thickness between about 0.5 mm and about 2 mm.

[0050] Receptors can have a substantially circular cross-section.

[0051] Receptors can have a cross-section that is substantially constant along the length of the receptor.

[0052] If the receptor is in the form of a strip or leaf, the strip or leaf can be rectangular in shape, with a width between about 2 mm and about 8 mm or between about 3 mm and about 5 mm. For example, a receptor in the form of a strip or leaf can have a width of about 4 mm.

[0053] If the receptor is in the form of a strip or a blade, the strip or blade may have a rectangular shape and a thickness between about 0.03 mm and about 0.15 mm or between about 0.05 mm and about 0.09 mm. For example, a receptor in the form of a strip or blade may have a thickness of about 0.07 mm or about 0.06 mm.

[0054] The receptor can be formed of any material capable of being inductively heated to a temperature sufficient to generate aerosols from the aerosol-generating matrix. For example, the receptor may include metal or carbon.

[0055] The sensor may include or be composed of ferromagnetic materials, such as ferromagnetic alloys, ferritic iron, ferromagnetic steel, or stainless steel. Suitable sensors may be aluminum or include aluminum. The sensor may be formed from 400 series stainless steel (e.g., grade 410, 420, or 430 stainless steel). When positioned within an electromagnetic field with similar frequency and field strength, different materials will dissipate different amounts of energy.

[0056] Therefore, parameters of the sensor, such as material type, length, width, and thickness, can all be changed to provide the desired power dissipation within a known electromagnetic field. The sensor can be heated to temperatures exceeding 250 degrees Celsius.

[0057] Suitable receptors may include a non-metallic core having a metallic layer disposed on the non-metallic core, such as metallic traces formed on the surface of a ceramic core. The receptor may have an outer protective layer, such as a ceramic or glass protective layer encapsulating the receptor. The receptor may include a protective coating formed of glass, ceramic, or inert metal on the core of the receptor material.

[0058] The receptor can be a multi-material receptor, and can include a first receptor material and a second receptor material.

[0059] The aerosol-generating product may also include a third hollow tube, which may be located upstream of the cooling section.

[0060] Adding a third hollow tube positioned upstream of the cooling section in an aerosol-generating article can serve as a path for airflow management, helping to regulate the aerosol temperature and ensure stable cooling before inhalation. This helps maintain the desired aerosol temperature for a comfortable and pleasant user experience. The third hollow tube can also act as a reservoir for additional flavorings or additives, such as flavor capsules, thus facilitating further customization of the aerosol's taste and aroma. By including this feature, the aerosol-generating article can offer users enhanced versatility and personalization options. Furthermore, positioning the third hollow tube upstream of the cooling section optimizes the overall airflow dynamics of the aerosol-generating article, contributing to efficient aerosol generation and delivery.

[0061] The inner diameter of the third hollow tube can be smaller than that of the second hollow tube. This smaller diameter facilitates a controlled airflow path within the device. As aerosols travel from the second hollow tube (which may contain flavor capsules or other additives) into the third hollow tube, the narrower diameter helps maintain a stable flow rate and pressure, thereby optimizing aerosol distribution. This ensures a smooth and satisfying inhalation experience for the user.

[0062] The smaller inner diameter of the third hollow tube can act as a limiting point in the airflow path, which can enhance the mixing of the aerosol with any additional flavorings or additives present in the second hollow tube. This promotes thorough blending of the aerosol with flavor components, resulting in a more uniform and flavorful vapor for the user to enjoy.

[0063] The controlled airflow path facilitated by the smaller diameter of the third hollow tube ensures that the flavor capsule remains firmly positioned within the second hollow tube. This prevents unintended movement or displacement of the flavor capsule during operation, thereby maintaining its stability and ensuring the stable performance of the device.

[0064] The inner diameter of the third hollow tube can be equal to that of the second hollow tube. Ensuring that the inner diameter of the third hollow tube matches that of the second promotes stable airflow throughout the device, which helps maintain predictable aerosol delivery to the user. This stability ensures a reliable user experience without fluctuations in airflow dynamics. Having equal inner diameters facilitates efficient distribution and mixing of flavor components or additives from the second to the third tube. This ensures that the aerosol passes uniformly through the flavoring agent, resulting in a consistent flavor experience. Uniform inner diameters simplify the design and manufacturing process, reducing complexity and ensuring a streamlined device construction. In summary, matching the inner diameter of the third hollow tube to that of the second hollow tube improves the performance of aerosol-generated articles, flavor delivery, and manufacturing efficiency.

[0065] The first hollow tube can be a hollow acetate tube. Using a hollow acetate tube as the first hollow tube in aerosol-generating products offers several advantages. Acetate is chosen because of its lightweight and durable properties, ensuring that the first hollow tube can withstand the stresses of use without compromising its integrity. Additionally, acetate exhibits good heat resistance, maintaining its structural integrity even at the high temperatures generated during aerosol production. The chemical stability of acetate ensures that it does not react with aerosols or flavoring agents, thus preserving the purity and flavor characteristics of the aerosol. Furthermore, the manufacturability of acetate facilitates efficient production processes, contributing to the cost-effectiveness and streamlined manufacturing of aerosol-generating products. In summary, the use of hollow acetate tubes enhances the durability, heat resistance, chemical stability, and manufacturability of the device, ensuring a reliable and consistent user experience.

[0066] The second hollow tube can be a thin hollow acetate tube.

[0067] The lateral shape of the through-hole can correspond to the lateral shape of the flavor capsule. Aligning the lateral shape of the through-hole with the lateral shape of the flavor capsule ensures better fit and alignment during insertion. This alignment enhances the seal between the capsule and the aerosol-generating article, thereby minimizing leakage and maintaining the integrity of flavor characteristics. Additionally, it optimizes airflow dynamics within the aerosol-generating article, thus promoting efficient aerosol generation and delivery to the user. By reducing airflow disturbance and ensuring a tight fit, this design choice contributes to a smoother and more enjoyable overall vaporization experience.

[0068] Aerosol generating articles may include filter tip section packaging paper extending from a downstream end to an upstream end of at least a portion of the aerosol generating article, and may cover the circumferential surface of the aerosol generating article, preferably a first hollow tube, more preferably a cooling section. The filter tip section packaging paper, extending from the downstream end to the upstream end of the aerosol generating article and specifically covering the cooling section, can provide protection for the device against external factors such as dust or debris. The packaging paper can enhance the aesthetics of the aerosol generating article, potentially featuring attractive graphics or branding. Additionally, the packaging paper, due to its tactile surface, can improve user grip and comfort. When covering the cooling section, the paper can act as insulation, helping to maintain the desired aerosol temperature for a stable vapor experience. In summary, filter tip section packaging paper can improve the protection, appearance, usability, and potentially enhance the thermal performance of the aerosol generating article, thereby contributing to an improved user experience.

[0069] Aerosol-generating articles may include a substrate wrapping paper that covers the circumferential surface of the substrate. Providing substrate wrapping paper covering the circumferential surface of the substrate provides protection, shielding the substrate from external factors such as dust or moisture, thereby maintaining its integrity and performance. The wrapping paper can enhance the aesthetics of aerosol-generated articles by creating conditions for visually appealing graphics or branding. Additionally, the wrapping paper allows for customization, enabling manufacturers to cater to diverse consumer preferences. The wrapping paper also contributes to user comfort, providing a pleasant tactile surface for gripping and handling. Furthermore, the wrapping paper can serve as a platform for branding and marketing campaigns, helping to enhance brand awareness and recognition. In summary, substrate wrapping paper adds value to aerosol-generated articles by providing protection, improving aesthetics, enabling customization, enhancing comfort, and facilitating brand promotion opportunities.

[0070] The second hollow tube may include at least one perforation that allows ambient air to be drawn laterally into it. Integrating at least one perforation within the second hollow tube to allow for lateral air intake can help regulate airflow within the tube, giving the user more control over their vapor experience. This airflow can help regulate the aerosol temperature, preventing overheating and ensuring user comfort. Introducing ambient air can dilute the aerosol, making it gentler for inhalation, which may be preferred for some users. Additionally, the perforation prevents the formation of a vacuum within the tube, ensuring stable aerosol delivery and preventing device malfunction. Overall, these perforations improve airflow regulation, temperature control, aerosol dilution, and device reliability, resulting in a more pleasant vapor experience.

[0071] Aerosol generating articles may consist of a cooling section, a main filter, a matrix portion, a front bar, and one or both of the filter tip section packaging paper and the matrix portion packaging paper. Aerosol generating articles consist of several basic components, including a cooling section, a main filter, a matrix portion, a front bar, and optionally, filter tip section packaging paper or matrix portion packaging paper, or both.

[0072] The cooling section plays a crucial role in reducing the temperature of the aerosol after its formation, thus ensuring a comfortable vapor experience. The main filter, located distal to the matrix section, filters out particulates and harmful substances from the aerosol, improving its purity and safety. The matrix section houses the aerosol-forming matrix and may contain features such as sensors used for efficient heating. The front bar, located proximal to the matrix section, provides structural support and helps secure the matrix within the device.

[0073] Optionally, the filter tip section packaging paper and the matrix section packaging paper can cover the corresponding circumferential surfaces of their respective components. These packaging papers can provide protection, improve aesthetics, and serve as a platform for branding, thereby enhancing the overall appeal of aerosol-generated articles.

[0074] The aerosol generation system may include a retainer comprising a cavity for receiving the aerosol-generated article, and the aerosol generation system may include a flavor capsule. The aerosol generation system may include a capsule insertion tool, wherein the capsule insertion tool may be configured to insert a flavor capsule into a second hollow tube of the aerosol-generated article via a first hollow tube.

[0075] The aerosol generation system comprises several components. These include a retainer with a cavity for containing the aerosol-generated article, a flavor capsule, and a capsule insertion tool. The retainer serves as a housing for the device, providing robust storage space. The flavor capsule contains additives or flavoring agents, allowing the user to customize the flavor of their aerosol. The capsule insertion tool is configured to facilitate the insertion of the flavor capsule into the aerosol-generated article. The capsule insertion tool functions by delivering the capsule through a first hollow tube into a second hollow tube of the device.

[0076] These components work together to provide users with a convenient and customizable vapor experience, allowing them to easily enjoy their preferred flavors.

[0077] This invention provides an aerosol-generating article with an enhanced consumer experience by providing a rod configuration that allows for the insertion of flavor capsules while avoiding damage to filter segments during the flavor capsule insertion process.

[0084] As used herein, the term "aerosol generating article" refers to an apparatus that interacts with an aerosol generating article to generate aerosols.

[0085] As used herein, when used in conjunction with aerosol or smoke generating articles or components or portions thereof, the term "proximal" refers to the user end or mouth end, and the term "distal" refers to the end opposite the downstream end.

[0086] An aerosol generating article may include an orifice through which aerosols exit the aerosol generating article and are delivered to a user during use. The orifice may also be referred to as a downstream end.

[0088] As used herein with reference to the invention, the term "smoking" in relation to apparatus, articles, systems, substrates, or otherwise does not refer to conventional smoking in which the aerosol-forming substrate is completely or at least partially burned. The aerosol-generating articles of the present invention are arranged to heat the aerosol-forming substrate to a temperature below the combustion temperature of the aerosol-forming substrate but at or above the temperature at which one or more volatile compounds of the aerosol-forming substrate are released to form an inhalable aerosol.

The microprocessor may be part of a controller. The circuit system may include additional electronic components. The circuit system may be configured to regulate the power supply to a heating element.

Power may be supplied to the heating element in the form of current pulses. The circuit system may be configured to monitor the resistance of the heating element and preferably control the power supply to the heating element based on the resistance of the heating element.

[0090] Aerosol generating articles may include a power source, typically a battery, within the body of the aerosol generating article. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery (e.g., lithium-cobalt, lithium-iron-phosphate, lithium titanate, or lithium-polymer battery). Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity sufficient to store enough energy for one or more uses; for example, the power source may have sufficient capacity to continuously generate aerosols for a period of approximately six minutes or multiples of six minutes. In another instance, the power source may have sufficient capacity to provide a predetermined number of discontinuous activations of the suction or heating element.

[0091] The cavity of the aerosol-generating article may have an open end into which the aerosol-generating article is inserted. The open end may be a downstream end. The cavity may have a closed end opposite the open end. The closed end may be the base of the cavity. The closed end may be closed except for providing air vents disposed in the base.

The cavity can have an elliptical or rectangular cross-section. The cavity can have an inner diameter corresponding to the outer diameter of the aerosol-generating article.

[0093] The airflow channel can extend through the aerosol-generating article and into the cavity. Ambient air can be drawn into the aerosol-generating article, into the cavity, and then drawn towards the user through the airflow channel. A mouthpiece can be positioned downstream of the cavity, or the user can inhale directly from the aerosol-generating article. The airflow channel can extend through the mouthpiece.

[0094] In any aspect of this disclosure, the heating element (such as a sensor) may include a resistive material. Suitable resistive materials 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, platinum, gold, and silver. 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, gold-containing alloys, and iron-containing alloys, as well as alloys based on nickel, iron, cobalt, stainless steel, and Timetal. ® And superalloys based on iron-manganese-aluminum alloys. In composite materials, resistive materials can be optionally embedded in, encapsulated in, or coated with insulating materials, or vice versa, depending on the energy transfer kinetics and desired external physicochemical properties.

[0095] As described, in any aspect of this disclosure, the heating element may be part of an aerosol-generating article. The aerosol-generating article may include an internal heating element, an external heating element, or both, wherein “internal” and “external” refer to the aerosol-forming matrix. The internal heating element may take any suitable form. For example, the internal heating element may take the form of a heating blade. Alternatively, the internal heater may take the form of a sleeve or substrate with different conductive portions, or a resistance metal tube. Alternatively, the internal heating element may be one or more heating needles or rods extending through the center of the aerosol-forming matrix. Other alternatives include heating wires or filaments, such as Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wires, or heating plates. Optionally, the internal heating element may be deposited in or on a rigid carrier material. In one such embodiment, the resistance heating element may be formed using a metal having a defined relationship between temperature and resistivity. In such an exemplary device, the metal may be formed as a rail on a suitable insulating material (such as a ceramic material) and then sandwiched in another insulating material (such as glass). Heaters formed in this way can be used to both heat and monitor the temperature of the heating element during operation.

[0096] The external heating element can take any suitable form. For example, it can take the form of one or more flexible heating foils on a dielectric substrate (such as polyimide). The flexible heating foil can be shaped to conform to the periphery of the matrix receiving cavity. Alternatively, the external heating element can take the form of a metal mesh or multiple metal meshes, a flexible printed circuit board, a molded interconnect device (MID), a ceramic heater, a flexible carbon fiber heater, or can be formed on a suitable shaped substrate using coating techniques (such as plasma vapor deposition). The external heating element can also be formed using a metal with a defined relationship between temperature and resistivity. In such an exemplary device, the metal can be formed as a rail between two layers of suitable insulating material. An external heating element formed in this way can be used to both heat and monitor the temperature of the external heating element during operation.

[0097] As an alternative to resistance heating elements, heating elements can be configured as induction heating elements. Induction heating elements can include an induction coil and a sensor. Generally, the sensor is a material capable of generating heat when penetrated by an alternating magnetic field. When located in an alternating magnetic field, if the sensor is conductive, eddy currents are typically induced by the alternating magnetic field. If the sensor is magnetic, another effect that typically contributes to heating is often referred to as hysteresis loss. Hysteresis loss occurs primarily due to the movement of magnetic domains within the sensor, as the magnetic orientation of these domains aligns with the alternating magnetic field. Another effect contributing to hysteresis loss is when magnetic domains grow or shrink within the sensor. Typically, all these changes occurring in the sensor at the nanoscale or below are referred to as "hysteresis loss" because they generate heat within the sensor. Therefore, if the sensor is both magnetic and conductive, both hysteresis loss and eddy current generation contribute to heating the sensor. If the sensor is magnetic but non-conductive, hysteresis loss will be the only means by which the sensor will heat up when penetrated by an alternating magnetic field. According to the present invention, the sensor can be conductive or magnetic, or both. An alternating magnetic field generated by one or more induction coils heats the sensor, which then transfers the heat to the aerosol-forming matrix to induce aerosol formation. Heat transfer can be primarily via thermal conduction. This heat transfer is optimal if the sensor is in close thermal contact with the aerosol-forming matrix.

[0098] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming matrix capable of releasing volatile compounds that can form aerosols. For example, an aerosol-generating article can be a smoking article that generates aerosols that can be inhaled directly into the lungs of a user through their mouth. Aerosol-generating articles can be disposable.

[0099] As used herein, the term "aerosol forming matrix" refers to a matrix capable of releasing one or more volatile compounds that can form aerosols. Such volatile compounds can be released by heating the aerosol forming matrix. The aerosol forming matrix may suitably be part of an aerosol-generating article or a smoking article.

[0100] The aerosol forming matrix can be a solid aerosol forming matrix. It can include both solid and liquid components. The aerosol forming matrix can include tobacco-containing materials containing volatile tobacco flavor compounds released from the matrix upon heating. The aerosol forming matrix can also include non-tobacco materials. Furthermore, the aerosol forming matrix can include aerosol forming agents that contribute to the formation of dense and stable aerosols. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0101] The aerosol-generating matrix preferably comprises: homogenized tobacco material, an aerosol forming agent, and water. Providing homogenized tobacco material can improve aerosol generation, nicotine content, and aroma characteristics of aerosols generated during the heating of aerosol-generating articles. Specifically, the process of manufacturing homogenized tobacco involves grinding tobacco leaves, which more effectively releases nicotine and aroma upon heating.

[0102] As used herein, the term "aerosol generation system" refers to a combination of an aerosol generating article and an aerosol forming matrix. When the aerosol forming matrix forms part of an aerosol generating article, the aerosol generation system refers to a combination of the aerosol generating article and the aerosol generating article. In an aerosol generation system, the aerosol forming matrix and the aerosol generating article cooperate to generate aerosols.

[0138] Aerosol-generated products according to any of the foregoing examples

[0139] A retainer, the retainer including a cavity for receiving the aerosol-generated article,

[0140] Flavor capsules

[0141] A capsule insertion tool, wherein the capsule insertion tool is configured to insert the flavor capsule into a second hollow tube of the aerosol-generating article via the first hollow tube.

[0142] The features described with respect to one embodiment can also be applied to other embodiments of the invention.

[0143] The invention will be further described by way of example only with reference to the accompanying drawings, in which:

[0144] Figure 1 This is a schematic longitudinal cross-sectional view of the aerosol-generated product.

[0145] Figure 2 This is a schematic longitudinal cross-sectional view of the aerosol-generated product, showing the insertion process of the flavor capsule.

[0146] Figure 3 This is a schematic longitudinal cross-sectional view of another aerosol-generated product.

[0147] Figure 4 This is a schematic diagram showing different cross-sections of the first hollow tube and the corresponding insertion tool.

[0148] Figure 1 An aerosol generating article 10 configured to receive a flavor capsule 28 (not shown) is shown, wherein the aerosol generating article 10 includes an upstream end and a downstream end. The upstream end is configured to connect to a retainer for the aerosol generating article 10. The aerosol generating article 10 includes a cooling section disposed at the downstream end, the cooling section including a first hollow tube 12 and a second hollow tube 14. This section is specifically designed to regulate the flow of the aerosol to reduce the temperature, thereby optimizing its performance, improving user comfort, or achieving desired operating conditions. The first hollow tube 12 includes a through-hole for inserting the flavor capsule 28, while the second hollow tube 14, located upstream of the first hollow tube 12, is configured to provide space for accommodating the flavor capsule 28. The inner diameter of the second hollow tube 14 is larger than the inner diameter of the first hollow tube 12, thereby ensuring sufficient space for the flavor capsule 28. Furthermore, the inner diameter of the second hollow tube 14 matches or exceeds the outer diameter of the flavor capsule 28, thereby ensuring that it remains within the second hollow tube 14 after insertion.

[0149] Furthermore, the aerosol generating article 10 includes a matrix portion 18 positioned upstream of a cooling section, the matrix portion containing an aerosol forming matrix. Additionally, the aerosol generating article includes a main filter 16 located downstream of and in direct contact with the matrix portion 18, while also positioned upstream of the cooling section. Furthermore, the article 10 includes a front rod 22 located upstream of the matrix portion 18. The matrix portion 18 itself includes a sensor 20 for promoting aerosol formation. When located within a undulating electromagnetic field, eddy currents induced in the sensor cause heating of the sensor. The sensor 20 is arranged in thermal contact with the aerosol generating matrix. Therefore, as the sensor heats up, the aerosol generating matrix is ​​heated by the sensor 20 to generate aerosols.

[0150] Furthermore, the aerosol generating article 10 is characterized by a filter tip section packaging paper 24 that extends from the downstream end to the upstream end of the aerosol generating article 10 over a portion of the aerosol generating article 10 and covers the circumferential surface of the aerosol generating article, preferably the first hollow tube 12, and more preferably the cooling section. Additionally, the second hollow tube 14 includes at least one perforation that allows ambient air to be laterally drawn into the second hollow tube. This design enhances the consumer experience by providing a lever configuration that allows for flavor capsule insertion while preventing damage to the filter section during flavor capsule insertion.

[0151] Compared to the known configuration, the positions of the main filter 16 and the cooling section have been interchanged. Therefore, the insertion of the flavor capsule is provided without requiring the user to modify the product by first forming holes in the filter section to insert the flavor capsule 28.

[0152] Figure 2 The diagram shows the insertion of the sac into the sac as shown in the diagram. Figure 1 The method in the aerosol generating apparatus 1 shown (from top to bottom) is illustrated. As can be seen from the process steps that need to be performed by the user, not only is the insertion method simpler, but the cooling section and the main filter 16 are not modified in any way, so the performance characteristics of the consumable remain unchanged. In an aerosol generating system including the aerosol generating article 10 as described, a retainer equipped with a cavity for receiving the aerosol generating article 10, a flavor capsule 28, and a capsule insertion tool 26, the process of inserting the flavor capsule 28 can be described as follows.

[0153] First, the user prepares the system to ensure proper alignment of the aerosol generating article 10 with the cavity of the retainer for smooth insertion. Then, the flavor capsule 28 is loaded into the capsule insertion tool 26 and held securely in place for insertion.

[0154] The user guides the capsule insertion tool 26 through the through-hole of the first hollow tube 12 of the aerosol-generated article 10, carefully guiding it through while avoiding any obstructions. Upon reaching the desired depth within the first hollow tube 12, the flavor capsule 28 is released, allowing it to enter the second hollow tube 14.

[0155] After confirming that the flavor capsule 28 is securely positioned within the second hollow tube 14, the capsule insertion tool 26 is carefully withdrawn from the first hollow tube 12, thereby ensuring that the flavor capsule 28 remains in its designated space.

[0156] This process ensures that the flavor capsule 28 is inserted into the aerosol-generating article 10 efficiently and reliably, allowing users to seamlessly enjoy their preferred flavor characteristics during aerosol generation without damaging the main filter 16.

[0157] exist Figure 3 Another embodiment of the aerosol generating article 10 is shown in the diagram. Essential to its function is a cooling section located at the upstream end, comprising a first hollow tube 12 and a second hollow tube 14. Additionally, a third hollow tube 30 is provided, integrated downstream of the second hollow tube 14. The purpose of the third hollow tube 30 is to further improve the airflow dynamics within the aerosol generating article 10 and to provide space for the flavor capsule 28. By introducing this component, the system optimizes the mixing of the aerosol with any additional flavoring agents or additives present in the second hollow tube 14. This enhancement ensures a more thorough blending of the aerosol with flavor components, thereby producing a stable, flavorful vapor for the user.

[0158] Furthermore, the third hollow tube 30 serves as a key element in maintaining a controlled airflow path. This controlled airflow path promotes the uniform distribution of aerosols throughout the device, ultimately enhancing the user experience by delivering a smoother and more satisfying inhalation experience.

[0159] The cooling section comprising the first hollow tube 12 and the second hollow tube 14 plays a crucial role in optimizing the performance of the aerosol-generating article 10. This section effectively regulates the aerosol flow to reduce its temperature, thereby improving user comfort and achieving desired operating conditions. The first hollow tube 12 serves as a through-hole for inserting the flavor capsule 28, while the second hollow tube 14 is specifically configured to provide space for accommodating the flavor capsule 28. The inner diameter of the second hollow tube exceeds that of the first hollow tube 12, thereby ensuring sufficient space for the flavor capsule 28 and facilitating its retention within the second hollow tube 14 after insertion.

[0160] This configuration facilitates easy insertion of the flavor capsule 28 while preventing damage to the filter segments during insertion. In other words, when designing a suitable aerosol generating device with multiple segments, the inner diameter of the segment configured to receive the flavor capsule should be defined on both sides by segments with smaller inner diameters. In this way, the flavor capsule 28 will remain within the intended segment after insertion without damaging the device.

[0161] As in Figure 4 As shown, another aspect is the possibility of matching the internal cross-sectional shape of the first hollow tube 12 with the external cross-sectional shape of the capsule insertion tool 26. In this way, it is possible to limit the flavor capsule insertion tool to be compatible with a given rod specification. Figure 4An example of such a shape for hollow cellulose acetate tow segments is shown, while a corresponding shape for the capsule insertion tool 26 is shown below a corresponding cross-section of the first hollow tube 12. By matching the shape of the first hollow tube 12 with the shape of the insertion tool 26, it is possible for the manufacturer of the aerosol-generating article 10 to limit the flavor capsules 28 that can be inserted into the aerosol-generating article 10. Thus, it is ensured that only correctly sized flavor capsules 28 are supplied in compatible insertion tools 26. Furthermore, by changing the internal shape of the first hollow tube 12, a special version of the product can be provided to the consumer, for example.
