Abstract
Description
AEROSOL GENERATING ARTICLEThis application claims the benefit of priority to Chinese patent application No. 202411642322.6, filed on November 15, 2024, entitled “Aerosol Generating Article” , the entire disclosures of which are incorporated herein by reference.TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of tobacco products, and more particularly to an aerosol generating article.BACKGROUND
[0002] Heat Not Burn (HNB) , also known as low temperature cigarette, is a novel type of tobacco product that incorporates a heating device and a stick, which is designed with an idea of “only heating but not burning" and is exemplified as “low temperature cigarettes” . The low temperature cigarettes can heat processed reconstituted tobacco (such as, a special stick) utilizing a special heating device (such as, a smoking device) to a certain temperature and to such an extent that the reconstituted tobacco is heated sufficiently to emit smoke for consumption. The HNB has advantages in that it is more harmless and can restore a pure taste and throat sensation of a cigarette, and thus can provide smokers with a nearest alternative to traditional cigarettes.
[0003] HNB product includes a heating device and a HNB stick. The HNB stick generally includes an aerosol generating substrate, a cooling segment and a filter segment. The aerosol generating substrate is an important part. The aerosol generating substrate is heated in a heating chamber and emits smoke similar to traditional cigarettes, and then the smoke passes through the cooling segment and the filter segment for the smokers to inhale.
[0004] In existing HNB stick on the market, the aerosol generating substrate can generate smoke mainly using reconstituted tobacco sheets or tobacco shreds as a core material and glycerol or propylene glycol as an aerosol generating agent with addition of flavors and other components through a lower heating temperature (usually 300℃-350℃) to achieve a smoking effect. HNB products release fewer harmful substances, and actual heating temperature is significantly lower than traditional tobacco, which results in less smoke release and reduced smoking sensation. To increase smoke amount of the product, the amount of glycerol and propylene glycol needs to be increased. However, glycerol itself has good hygroscopicity, which can result in high hygroscopicity of the product and cause great inconvenience for later processing and storage. Moreover, after opening the packaging, high hygroscopicity can cause uneven smoking of different cigarettes. In addition, the conduction of heat requires a time process, and the smoke amount of the same cigarette at different times is also inconsistent.
[0005] In order to increase the smoke amount, existing technologies have proposed using a capsule encapsulating propylene glycol / glycerol as an aerosol generating substrate, but most related technologies only use the capsule as a part of an aerosol generating material. Some patents also mention using a pure capsule directly as aerosol generating materials and placing the capsule in an aerosol generating substrate segment, where a single capsule is used and there is a need to address a problem of core material outflow after capsule rupture, for example, by absorbing the core material of the capsule using an absorbent pad. However, relevant technical literature has not clearly proposed how to directly use the capsule as an aerosol generating material, nor has solved a series of technical problems of directly using the capsule as the aerosol generating material. SUMMARY OF THE DISCLOSURE
[0006] Therefore, an embodiment of the present disclosure provides a HNB product (also referred to as a heated tobacco product (HTP) , a low-temperature cigarette product, or generically as a heated product) , namely an aerosol generating article, which can increase smoke release amount, decrease heating release temperature, reduce smoke hazards and enhance smoking sensation.
[0007] An embodiment of the present disclosure provides an aerosol generating article including an aerosol generating substrate segment. The aerosol generating substrate segment includes one or more aerosol generating capsules, and the aerosol generating capsules are limited in a fixed area or a restricted movable area by a component with designed structure. The capsule is commonly known as seamless capsule and is typically spherical. The fixed area refers to an area where the component with designed structure is fixed in a tube of the aerosol generating article, so that a restricted area of the aerosol generating capsules is also fixed. The restricted movable area refers to an area where the component with designed structure is movable in the tube, so that the restricted area of the aerosol generating capsules is movable, but the movable area itself is also limited by a movement mode of the component with designed structure. During heating the aerosol generating capsules, the aerosol generating capsule near a heat source is first ruptured. The ruptured capsule may cause collapse and accumulation, and attachment of core liquid may lead to increased draw resistance. By providing the component with designed structure to limit the aerosol generating capsules in an area or limit the aerosol generating capsules in separated areas, a contact between the aerosol generating capsules and the tube or between the aerosol generating capsules can be reduced, which can reduce draw resistance. Furthermore, the component with designed structure can increase the filling porosity of the aerosol generating capsules, which is conductive to reducing the draw resistance.
[0008] According to some embodiments, the component with designed structure is fixed at a designated position in the aerosol generating article. The designated position generally refers to an area where the aerosol generating substrate segment is limited.
[0009] According to some embodiments, the aerosol generating article further includes a limiting part, and the component with designed structure is limited in the aerosol generating substrate segment by the limiting part.
[0010] According to some embodiments, the component with designed structure is movable in the aerosol generating substrate segment. The movable component with designed structure can further reduce capsule accumulation and reduce draw resistance.
[0011] According to some embodiments, the aerosol generating capsules are separated in a plurality of specific areas by the component with designed structure, and the aerosol generating capsules are limited in the plurality of specific areas. Separating the aerosol generating capsules can also reduce capsule accumulation and reduce draw resistance.
[0012] According to some embodiments, the aerosol generating capsules are arranged in the fixed area or the restricted movable area in a regular form. Although production difficulty may be increased, regular arrangement can reduce draw resistance.
[0013] According to some embodiments, the aerosol generating capsules are arranged in the fixed area or the restricted movable area in an irregular form.
[0014] According to some embodiments, the component with designed structure is formed of a metal material. The metal material generally has excellent thermal conductivity, which can effectively absorb heat and quickly conduct the heat to the aerosol generating capsules, thereby increasing aerosol release speed.
[0015] According to some embodiments, the component with designed structure is formed of a heat resistant material. The heat resistant material can withstand at least the heating temperature.
[0016] According to some embodiments, the component with designed structure includes a heating channel configured for receiving a heating member to heat the aerosol generating article. The heating channel can facilitate the insertion of the heating member and maintain cleanliness of the heating member.
[0017] According to some embodiments, a length of the aerosol generating substrate segment accounts for 10%to 60%of a total length of the aerosol generating article. Due to the adjustable particle size of the aerosol generating capsules, in order to adapt to different heating methods or release effects, the length of the aerosol generating substrate segment filled with the aerosol generating capsules can be adjusted in a wide adjustment range.
[0018] According to some embodiments, the aerosol generating capsules have a particle size of 1 mm to 3 mm, and preferably 1.5 mm to 2.5 mm. When the smoke release amount is designed to be the same, if the aerosol generating capsules have a too small particle size, then each aerosol generating capsules have a low amount of the core material, and thus, although uniformity of smoke release may be improved, a reduced carrying capacity of an aerosol generating agent may also be caused, and filling void volume fraction may also be reduced, which may both have an adverse effect on smoke release effect. Therefore, an appropriate particle size, especially a moderate particle size, can ensure a good smoking experience, and can also prevent the core material of the aerosol generating capsules with a large particle size flowing out from the aerosol generating article.
[0019] According to some embodiments, the aerosol generating capsules have a filling amount of 0.05 g to 0.5 g. In some embodiments, the aerosol generating capsules have a filling amount of 0.1 g to 0.3 g. At a certain smoke release amount, a higher filling amount may cause a waste of material, and a lower filling amount may reduce aerosol generating continuity, thus a moderate filling amount can ensure a good smoking sensation.
[0020] According to some embodiments, the aerosol generating capsules have a filling amount of 5 capsules to 100 capsules. In some embodiments, the aerosol generating capsules have a filling amount of 15 capsules to 30 capsules. When the smoke release amount is designed to be the same, a lower number of the aerosol generating capsules may lead to too much core material per capsule, which can easily cause the core material to flow out from the aerosol generating article, and a higher number of the aerosol generating capsules may lead to an increase in draw resistance, which will affect smoking experience. Moreover, a moderate filling amount can also ensure a uniform aerosol release.
[0021] According to some embodiments, the aerosol generating substrate segment does not include other aerosol generating materials other than the aerosol generating capsule. Since different aerosol generating materials have inconsistent heating release temperatures, the aerosol generating capsule can release at a lower temperature, and the heating release temperature can be thus further reduced. Using a single type of aerosol generating material, such as an aerosol generating capsule, can employ a lower heating release temperature while maintaining release speed, which can save energy consumption and reduce a potential hazardous component released at a high temperature.
[0022] In the aerosol generating article according to the embodiments of the present disclosure, the aerosol generating substrate segment includes one or more aerosol generating capsules, and the aerosol generating capsules are limited in a fixed area or a restricted movable area by a component with designed structure, which can reduce draw resistance and improve smoking experience. Furthermore, the component with designed structure can have various structures and fixing methods, which can better adapt to various aerosol generating capsules with different particle sizes, shapes and quantities. Furthermore, the component with designed structure includes a heating channel configured for receiving a heating member to heat the aerosol generating article, which can adapt to a center heating device.BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following provides a detailed explanation of the aerosol generating article according to some embodiments of the present disclosure.
[0041] Referring to FIG. 1, FIG. 1 schematically illustrates a structural view of an aerosol generating article 10 according to an embodiment of the present disclosure.
[0042] In some embodiments, the aerosol generating article 10 includes an aerosol generating substrate segment 101, and further includes a limiting part 102 and / or a filter segment 103. The limiting part 102 is adjacent to an end of the aerosol generating substrate segment 101 away from an end of the aerosol generating article 10, and the filter segment 103 may be adjacent to or spaced a certain distance from the limiting part 102.
[0043] In other embodiments, the limiting part 102 or the filter segment 103 may not be provided. For example, the filter segment 103 may be directly adjacent to the end of the aerosol generating substrate segment 101 away from the end of the aerosol generating article 10.
[0044] The aerosol generating substrate segment 101 includes one or more aerosol generating capsules 104. The aerosol generating capsules 104 are limited in the aerosol generating substrate segment 101 by the component with designed structure 109, and the component with designed structure 109 is limited in the aerosol generating substrate segment 101 by the limiting part 102.
[0045] In some embodiments, the position of the component with designed structure 109 may be fixed and unchangeable. For example, the component with designed structure may be fixed on an end of the limiting part 102 adjacent to the aerosol generating substrate segment 101.
[0046] In some embodiments, the position of the component with designed structure 109 may be movable. For example, the component with designed structure may freely move in the aerosol generating substrate segment 101.
[0047] The component with designed structure 109 can separate the aerosol generating capsules 104 in multiple specific areas. In some embodiments, the component with designed structure 109 may have various shapes and structures, and the spatial size and shape of different specific areas may be the same or different. In addition, the aerosol generating capsules 104 are arranged in these specific areas in a regular form or in an irregular form.
[0048] Referring to FIG. 2, FIG. 2 schematically illustrates a structural view of a component with designed structure 109 according to an embodiment of the present disclosure.
[0049] The component with designed structure 109 may only include a partition frame 91, as shown in part (a) of FIG. 2.
[0050] Furthermore, a fixing plate 92 may be installed at one or both ends of the partition frame 91, as shown in part (b) and part (c) of FIG. 2. An end surface of the fixing plate 92 may be circular, elliptical, square, diamond-shaped, etc., which is not limited by the present disclosure. The shape of the end surface and the thickness of two fixing plates 92 installed at both ends of the partition frame 91 may be the same or different.
[0051] Furthermore, an airflow channel is also provided on the fixing plate 92, which can allow airflow to pass through and have relatively low air resistance.
[0052] Furthermore, one or more airflow channels are distributed on the end surface of the fixing plate 92 and at a certain distance from a circumferential edge of the end surface, as shown in part (b) and part (c) of FIG. 2.
[0053] Referring to FIG. 3, FIG. 3 schematically illustrates a structural view of a component with designed structure 209 according to an embodiment of the present disclosure.
[0054] In some embodiments, the component with designed structure 209 also includes a partition frame 91 and a fixing plate 92 at one end of the partition frame 91. The difference from the embodiment shown in FIG. 2 is that in the embodiment shown in FIG. 3, the partition frame 91 is also fixedly connected with a limiting member 93, so as to synchronously fix the position of the component with designed structure when the limiting member 93 is fixed in the tube of the aerosol generating article. In addition, in the embodiment shown in FIG. 3, multiple airflow channels are not only distributed on the end surface of the fixing plate 92, but also on an end surface of the limiting member 93, as shown in part (a) , part (b) and part (c) of FIG. 3, where part (c) of FIG. 3 illustrates a schematic view showing multiple aerosol generating capsules are filled.
[0055] Still referring to FIG. 1, in some embodiments, the limiting part 102 may be a prefabricated component with an airflow channel, or a structural component such as a rolled sheet member. The material of the limiting part may include, but is not limited to, any one of the following: plant fiber, resin, metal, etc. On the one hand, the airflow channel can reduce the draw resistance, and on the other hand, the airflow channel can also prevent the aerosol generating capsules 104 from passing through. The material of the rolled sheet member may include, but is not limited to, any one of the following: paper, resin sheet (such as polylactic acid sheet) , metal sheet, etc.
[0056] The limiting part 102 can not only limit the component with designed structure 109, but also have a cooling effect on the smoke to avoid excessive temperature of the smoke.
[0057] In some embodiments, the filter segment 103 may include one or more filter members. Various filter members can be sequentially connected along an axial or radial direction of the filter segment. The filter members may be a solid, hollow, or porous filter rod, which is not limited by the present disclosure. The filter rod may be formed by processing one or more fibers.
[0058] Still referring to FIG. 1, in some embodiments, a seal 105 is provided at one end of the aerosol generating substrate segment 101 adjacent to an end of the aerosol generating article 10. The seal 105 may be formed of paper, non-woven fabric, fabric, a thermally conductive material, etc. The seal 105 may be directly adhered to an end surface of the aerosol generating substrate segment 101. The thermally conductive material may be metal foil, such as aluminum foil and tin foil, which can increase thermal conductivity and reduce heating waiting time during suction. Except for specific embodiments, the seal is generally permeable or has permeable holes to ensure that airflow can enter the aerosol generating article.
[0059] Referring to FIG. 4, FIG. 4 schematically illustrates a structural view of an aerosol generating article 20 according to another embodiment of the present disclosure.
[0060] In some embodiments, the aerosol generating article 20 includes an aerosol generating substrate segment 201, and may further include a filter segment 203. The aerosol generating substrate segment 201 includes one or more aerosol generating capsules 204. The aerosol generating capsules 204 are limited in a fixed area by a component with designed structure 209. Moreover, in some embodiments, the seal 105 and the limiting part 102 shown in FIG. 1 may be not provided. The component with designed structure 209 can provide a sealing effect on both ends of the aerosol generating substrate segment 201 to prevent the aerosol generating capsules 204 in the aerosol generating substrate segment 201 falling off from both ends. A limiting member end of the component with designed structure can be fixed in the tube, and a fixing plate end is flush with an end of the aerosol generating article. There is a certain gap between the fixing plate end and the tube, but the aerosol generating capsules 204 will not falling off from the gap.
[0061] FIG. 5 schematically illustrates a structural view of a component with designed structure 309 according to another embodiment of the present disclosure.
[0062] Referring to part (a) , part (b) , part (c) and part (d) of FIG. 5, in some embodiments, the component with designed structure 309 includes a partition frame 94 and a fixing plate 92 connected with the partition frame 94. In the component with designed structure as shown in part (c) of FIG. 5, the partition frame 94 is also fixedly connected with a limiting member 93 so as to synchronously fix a position of the component with designed structure when the limiting member 93 is fixed in a tube of the aerosol generating article. In addition, in the embodiment shown in FIG. 5, heating channels are provided at an axial center of the fixing plate 92 and the partition frame 94 to facilitate an insertion of a center heating member of a heating device. Although not explicitly shown in the drawing, through holes may also be provided on the heating channels to facilitate rapid heat conduction from the heating member in the heating channels to the aerosol generating capsules. The cross-section of the heating channels may be, but is not limited to, any one or more of the following: circular, elliptical, diamond-shaped, triangular, polygonal, irregular closed shape, etc., as long as the center heating member can be smoothly inserted.
[0063] Referring to FIGS. 4 and 5, in order to prevent the aerosol generating capsules 204 from falling off from the airflow channels at both ends of the component with designed structure, in the structural design shown in FIG. 4, a maximum aperture of the airflow channels may be designed to be smaller than a minimum particle size of the aerosol generating capsules 204 to ensure that the aerosol generating capsules 204 does not enter the airflow channels.
[0064] In some embodiments, the cross-sectional shape of the airflow channels may be the same or different. One or more airflow channels may be formed in the component with designed structure, and the airflow channels run through both ends of the component with designed structure.
[0065] In some embodiments, the cross-sectional shape of the airflow channel may be any one or more of the following: circular, elliptical, diamond-shaped, triangular, polygonal, irregular closed shape, etc.
[0066] During usage, the aerosol generating article may be placed on a suitable heating device, and the aerosol generating capsules may be ruptured by heating to generate aerosols. Compared with existing products using reconstituted tobacco sheets or tobacco shreds as the core material, the aerosol generating article can effectively increase the smoke amount. Moreover, the limiting effect of the component with designed structure on the aerosol generating capsules can prevent an increase in the draw resistance of the aerosol generating article.
[0067] In some embodiments, the shape of the aerosol generating capsules may be circular, elliptical, etc., and the particle size may be the same or different, which is not limited by the present disclosure. For example, in some embodiments, the particle size of the aerosol generating capsules may be designed to be 1 mm-3 mm. In some embodiments, the particle size of the aerosol generating capsules may be 1.5 mm -2.5 mm, for example, 2.0 mm.
[0068] Depending on different particle size of the aerosol generating capsules and different length of the aerosol generating substrate segment, the number or weight of the aerosol generating capsules filled in the aerosol generating substrate segment may also vary. For example, in some embodiments, the filling amount of the aerosol generating capsules is 5-100 capsules, and preferably 15-30 capsules. In some specific embodiments, 20 or more capsules may be preferred. For example, in some embodiments, the filling amount of the aerosol generating capsules is 0.05 g-0.5 g, and preferably 0.1 g-0.3 g.
[0069] In the aerosol generating article according to embodiments of the present disclosure, the aerosol generating article may have a lower heating release temperature. For example, in some embodiments, the heating release temperature of the aerosol generating article may be 180℃-280℃. In some embodiments, the heating release temperature of the aerosol generating article may be 220℃-260℃, such as 230℃, 240℃ and 250℃. At different heating temperatures, the amount of aerosol released by the aerosol generating capsules may vary.
[0070] In some embodiments, the aerosol generating substrate segment may only include the aerosol generating capsules described above, and does not include any other aerosol generating materials other than the aerosol generating capsules.
[0071] In some embodiments, the length of the aerosol generating substrate segment 101 may be arbitrarily set, for example, the length of the aerosol generating substrate segment 101 may be 10%to 60%of a total length of the aerosol generating article.
[0072] In some embodiments of the present disclosure, the core material of the aerosol generating capsules mainly includes an aerosol generating agent. The main component of the aerosol generating agent may include Propylene Glycol (PG) and / or Glycerol (VG) . The core material may be a colloid, a paste or a solid-liquid mixture.
[0073] In some embodiments, the material of the shell of the aerosol generating capsules may be a thermosetting resin. For example, the thermosetting resin is formed by curing epoxy resin under a photoinitiator.
[0074] In some embodiments, the material of the shell of the aerosol generating capsules may include, but is not limited to, any one or more of the following gelling agents: plant gel, animal gel, microbial gel, starch, modified starch materials, etc. The animal gel may be gelatin, fish gel, chitosan, etc., and the plant gel may be carrageenan, sodium alginate, gellan gum, tamarind gum, etc.
[0075] The thickness of the shell of the aerosol generating capsule 104 may be designed to be 30-150 μm, such as 50 μm, 80 μm, 100 μm, 120 μm and 140 μm.
[0076] The aerosol generating capsules according to the embodiments of the present disclosure can be prepared by various methods, such as the following method, and the like.
[0077] 40 weight parts of sunflower seed oil was heated to 100℃, and then, 7.1 weight parts of ethyl cellulose, 1.4 weight parts of beeswax, and 2.1 weight parts of palm wax were added therein while stirring, dissolved, and mixed well. Thereafter, the mixture was cooled to 60℃, and 24 weight parts of propylene glycol, 16 weight parts of glycerol, 2.4 weight parts of surfactant (prepared by Tween 80 and glycerol monooleate in a weight ratio of 1: 9) , 5 weight parts of mango flavor, and 2 weight parts of nicotine salt were added therein and stirred well, to complete preparation of the core material.
[0078] 5 weight parts of carrageenan and 3 weight parts of gellan gum were put into 82 weight parts of purified water, and heated at a temperature of 60℃ to 90℃ while stirring, to form a uniform solution. And then, 10 weight parts of glycerol was added and stirred well, to prepare a shell liquid.
[0079] The core material (inner layer) and the shell liquid were dropped into a liquid coolant (Medium-Chain Triglycerides, MCT) through a concentric dropper at a temperature controlled at 10℃ to 25℃, to form a wet capsule. Then, the wet capsule was stored at -10℃ to 10℃ for 10 hours, and dried at 20℃ to 30℃ and 20%to 50%humidity, to prepare a capsule article with a particle size of 2 mm and a shell thickness of 70 μm.
[0080] The aerosol generating article according to the embodiments of the present disclosure has strong universality and can be adapted to various heating devices, such as needle heating devices, plate ceramic heating devices and air heating devices.
[0081] When preparing the aerosol generating article, different tastes and suction effects may be produced by adjusting parameters such as the length of the aerosol generating substrate segment, the void volume fraction and particle size of the aerosol generating capsules to meet the needs and experiences of different smokers.
[0082] Although the present disclosure has been disclosed above, the present disclosure is not limited thereto.
