Description

Technical Field

[0001] This invention relates to the field of tobacco product technology, and more specifically to an aerosol-generating product. Background Technology

[0002] HNB (Heat Not Burn), also known as low-temperature cigarettes, is a new type of tobacco product that combines a heating device and a tobacco cartridge. Designed with the concept of "heating without burning," it uses a special heating device (the device) to heat processed tobacco (a special tobacco cartridge) to a certain temperature, enough to release smoke for inhalation. Its advantages include reduced harm and restoration of the pure taste and throat hit of traditional cigarettes, providing smokers with a smoking alternative that is closest to traditional cigarettes.

[0003] HNB consists of two parts: a heated tobacco device and an HNB cartridge. An HNB cartridge typically consists of three parts: a smoke-generating section, a cooling section, and a filter section. The smoke-generating section is an important component. After being heated in the heating chamber, the smoke-generating section emits smoke similar to that of traditional cigarettes. The smoke is then passed through the cooling section and the filter section before being inhaled by the user.

[0004] Currently available HNB (Heated Tobacco Bundle) cartridges primarily use reconstituted tobacco leaves or shredded tobacco as the core material, glycerin or propylene glycol as the smoke-generating agent, and flavoring ingredients. They generate smoke through a relatively low heating temperature (usually <350℃) to achieve the smoking effect. Although HNB products release fewer harmful substances, the actual heating temperature is significantly lower than traditional tobacco, resulting in less smoke and a less pleasant smoking experience. Increasing the amount of smoke produced requires increasing the amount of glycerin. However, glycerin itself has good hygroscopic properties, leading to high hygroscopicity in the product, causing significant inconvenience in later processing and storage. Furthermore, once the packaging is opened, the cigarette cannot be guaranteed to be protected, resulting in uneven smoking of different cigarettes. Additionally, heat transfer takes time, and the amount of smoke produced from the same cigarette may vary over time.

[0005] To increase smoke production, existing technologies have mentioned using propylene glycol / glycerol-coated capsules as aerosol-generating matrices, but most related technologies simply use capsules as a supplement to tobacco materials. Some patents also mention using pure capsules directly as aerosol-generating materials and placing them in the aerosol-generating matrix section; however, these technologies all use single capsules and need to address the problem of core material leakage after capsule rupture, for example, by using absorbent pads to absorb the capsule core material. It is evident that the relevant technical literature does not explicitly propose optimizing the properties of the aerosol-generating capsule core material to solve the technical problems of directly using capsules as aerosol-generating materials. Summary of the Invention

[0006] Therefore, the present invention provides an HNB product, namely an aerosol generating product, to increase the amount and duration of smoke generation, reduce the heating release temperature, and eliminate the need to install an absorbent pad to absorb the core liquid in the aerosol generating matrix section.

[0007] Therefore, the embodiments of the present invention provide the following technical solutions:

[0008] An aerosol generating product includes an aerosol generating matrix section, wherein the aerosol generating matrix section includes an aerosol generating capsule, and the aerosol generating capsule includes a core material, which is a paste, a colloid, or a solid-liquid mixture. When the aerosol generating capsule ruptures upon heating, the core material flows out. Liquid core material has good fluidity, easily flowing out in large quantities from the ruptured cracks, and is less likely to adhere to the capsule shell, especially when the content of the smoke-generating agents propylene glycol and glycerol is high. When the core material is a paste, a colloid, or a solid-liquid mixture, even under heating, the core material will not flow out instantly from the cracks, and the outflow is more likely to adhere to the capsule shell, thus effectively preventing the core material from flowing out of the aerosol generating product tube, and eliminating the need for a specific absorbent pad to absorb the core material.

[0009] Optionally or preferably, the aerosol generating matrix segment includes multiple aerosol generating capsules. With the same designed smoke release rate, a multi-capsule system reduces the amount of smoke-generating agent (e.g., propylene glycol / glycerol) in each capsule. During the heating and release process, the capsules closest to the heat source rupture first. Since each capsule contains less core material, the core material adheres to the capsule shell. The smoke-generating agent in the core material continues to evaporate upon heating, forming smoke and carrying away some heat. As the smoke-generating agent evaporates and is consumed, heat continues to accumulate, and capsules slightly farther from the heat source will also rupture. The corresponding smoke-generating agent in the core material is released and continues to evaporate, carrying away some heat, until the corresponding smoke-generating agent is nearly exhausted. Heat continues to accumulate, and capsules farther from the heat source will subsequently rupture. Therefore, multiple capsules rupture sequentially when continuously heated, preventing a large amount of core material from flowing out at once. This avoids the technical problem of a large amount of core material flowing out instantly after a single capsule ruptures, and also eliminates the need for a specific absorption pad to absorb the core material. Furthermore, the sequential rupture of multiple capsules and the gradual release of the smoke-generating agent result in better smoke continuity and stability, and a more uniform release.

[0010] Optionally or preferably, the particle size of the aerosol generating capsule is 1-3 mm, preferably 1.5-2.5 mm. When the smoke release is designed to be the same, if the capsule particle size is too small, the amount of core material in each capsule is lower. Although the uniformity of release will improve, it will also lead to a decrease in the carrying capacity of the smoke-generating agent and a reduction in the filling porosity, all of which adversely affect the smoke release effect. Therefore, a suitable particle size, especially a moderate particle size, can ensure a good inhalation experience and also prevent the problem of large-diameter capsule core material flowing out of the aerosol generating product.

[0011] Optionally or preferably, the aerosol generating capsule has a filling amount of 0.05–0.5 g, more preferably 0.1–0.3 g. When the amount of smoke released is constant, a higher filling amount may lead to material waste, while a lower filling amount will reduce the persistence of aerosol generation. Therefore, a moderate filling amount can ensure a good inhalation experience.

[0012] Optionally or preferably, the aerosol generating capsules have a filling quantity of 5 to 100 capsules, preferably 15 to 30 capsules. When the smoke release is designed to be the same, a lower number of capsules may result in too much core material in each capsule, which may cause the core material to flow out of the aerosol generating product; while a higher number of capsules will lead to an increase in draw resistance, affecting the vaping experience; at the same time, an appropriate filling quantity can also ensure the uniformity of smoke release.

[0013] Optionally or preferably, the aerosol generating matrix segment does not include other aerosol generating materials besides the aerosol generating capsule. Since different aerosol generating materials have different heating release temperatures, the aerosol generating capsule can release at a lower temperature, thus further reducing the heating release temperature. Using a single type of aerosol generating material, such as the aerosol generating capsule, allows for maintaining release efficiency while using a lower heating release temperature, thereby saving energy and reducing potentially harmful components released at high temperatures.

[0014] Optionally or preferably, the heating release temperature of the aerosol-generating product is 180–300°C, preferably 200–250°C. The release temperature of the aerosol-generating capsule is relatively low; at lower temperatures, the core material has weaker fluidity, thus adhering more easily to the capsule shell.

[0015] Optionally or preferably, the aerosol generating matrix segment does not include a carrier capable of absorbing the core material. The absence of a carrier for absorbing the core material results in a relatively simple composition of the aerosol generating matrix segment, thus reducing the hazard of the flue gas released upon heating, and also lowering the difficulty of manufacturing.

[0016] The aerosol generating product provided in this invention includes an aerosol generating capsule as the aerosol generating matrix section. The core material of the aerosol generating capsule is a paste, colloid, or solid-liquid mixture, which can achieve uniform, sufficient, and continuous vapor release at a certain heating temperature, improving the user's experience. Simultaneously, due to the relatively weak flowability and easier adhesion of the core material to the shell, the aerosol generating matrix section does not require a specific absorbent pad for the core liquid, reducing the structural complexity of the aerosol generating product. Moreover, the shell provides excellent protection for the core material inside the capsule, preventing quality changes due to external environmental influences and ensuring the stability of the core material during long-term product storage, thus better guaranteeing product quality.

[0024] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0025] To address the issues of low smoke output and high susceptibility to environmental factors in existing HNB (High-End Tobacco) cartridge products that primarily use reconstituted tobacco leaves or shredded tobacco as core materials, this invention provides an aerosol-generated product that can achieve uniform, sufficient, and continuous smoke release at lower heating temperatures, thereby enhancing the smoker's experience.

[0026] like Figure 1 The diagram shown is a structural schematic of an aerosol-generated product provided in an embodiment of the present invention.

[0027] In this example, the aerosol generating article 10 includes an aerosol generating matrix segment 101, which includes one or more aerosol generating capsules 104. The aerosol generating capsule 104 includes a core material, which is a paste, a colloid, or a solid-liquid mixture.

[0028] When heated at low temperatures, the core material can generate vapor. Using a core material that is a paste, colloid, or a solid-liquid mixture allows the aerosol generating capsule 104 to achieve uniform and sufficient vapor release under low-temperature heating, improving the smoker's experience. Furthermore, compared to a purely liquid vapor-generating agent, heating effectively increases the persistence of vapor release, enhancing the vaping experience. Additionally, compared to a single aerosol generating capsule, multiple aerosol generating capsules can result in better vapor persistence during heating.

[0029] In specific implementations, the shape of the aerosol generating capsule 104 can be circular, elliptical, etc., and the particle size can be the same or different; this embodiment of the invention does not limit this. For example, in some non-limiting embodiments, the particle size of the aerosol generating capsule 104 can be designed to be 1-3 mm, preferably 1.5-2.5 mm. In some specific embodiments, the particle size of the aerosol generating capsule 104 can be, for example, 1.8 mm, 2.0 mm, etc.

[0030] Depending on the particle size of the aerosol generating capsules 104 and the length of the aerosol generating matrix segment 101, the number or weight of aerosol generating capsules 104 filling the aerosol generating matrix segment 101 will vary. For example, in some embodiments, the filling amount of aerosol generating capsules 104 is 5 to 100 capsules, preferably 15 to 30 capsules, and in some specific embodiments, preferably more than 20 capsules. Furthermore, in some embodiments, the filling amount of aerosol generating capsules 104 is 0.05 to 0.5 g, preferably 0.1 to 0.3 g.

[0031] In the aerosol generating product provided in this embodiment of the invention, the aerosol generating capsule 104 can release at a certain temperature, that is, when heated to a certain temperature, the shell of the aerosol generating capsule 104 ruptures, and the core material releases smoke. For example, in some embodiments, the heating release temperature of the aerosol generating product is 180-300°C, preferably 200-250°C.

[0032] In this embodiment of the invention, the core material in the aerosol generating capsule is in a non-liquid form, which slows down the rate of smoke release and effectively improves the persistence of smoke generation. In specific implementation, it is preferable to use multiple small-particle-size aerosol generating capsules. During heating, the multiple aerosol generating capsules 104 will not rupture simultaneously due to their different positions and the different degrees of heating, which can further improve the persistence of smoke generation.

[0033] In some embodiments, the aerosol generating matrix segment may contain only the aforementioned aerosol generating capsule 104, and may not contain any other aerosol generating materials other than the aerosol generating capsule.

[0034] In other embodiments, the aerosol generating matrix segment may also include the aforementioned aerosol generating capsule 104 and other aerosol generating matrices or materials.

[0035] In some embodiments, the length of the aerosol generating matrix segment 101 can be set arbitrarily, for example, it can be 10% to 60% of the total length of the aerosol generating article 10.

[0036] In this embodiment of the invention, the core material of the aerosol generating capsule 104 mainly includes a smoke generator, and the mass ratio of the smoke generator to the core material of the aerosol generating capsule can be, for example, 4% to 60%.

[0037] In embodiments of the present invention, the main components of the smoke-generating agent include propylene glycol (PG) and / or glycerin (VG). For example, in one embodiment, the smoke-generating agent comprises propylene glycol and glycerin, which account for 4 to 60 wt% of the core material weight. In some specific embodiments, propylene glycol and glycerin may account for 15 to 50 wt% of the core material weight. In other specific embodiments, propylene glycol and glycerin may account for 25 to 45 wt% of the core material weight, for example, 25 wt%, 30 wt%, 35 wt%, 40 wt%, or 45 wt%, etc.

[0038] By combining propylene glycol and glycerin, a lower aerosol release temperature can be achieved while maintaining sufficient smoke release. Using encapsulated aerosol-generating materials allows the aerosol-generating product to achieve uniform and sufficient smoke release at lower heating temperatures, thereby reducing the energy consumption required for heating during inhalation, minimizing the release of harmful substances, and improving the inhaler's experience.

[0039] Glycerin produces more smoke and has a sweet taste. Propylene glycol produces smoke with a weaker visual effect, but it has a strong throat hit. Therefore, in practice, the ratio of propylene glycol to glycerin can be varied to suit the preferences of different smokers; for example, the ratio of glycerin to propylene glycol can be chosen in the range of 2:8 to 8:2.

[0040] In some embodiments, to provide a richer flavor, other ingredients may be added to the core material of the aerosol-generating capsule 104, such as, but not limited to, any one or more of the following: flavorings, extracts, nicotine, nicotine salts, etc. For example, in some embodiments, the core material further includes 0.1 to 20 wt% flavorings and / or extracts by weight of the core material; in some embodiments, the core material further includes 0.1 to 20 wt% nicotine and / or nicotine salts by weight of the core material. Extracts may be animal or plant extracts, such as musk, ambergris, tea extract, monk fruit extract, etc., and the specific flavor can be adjusted as needed.

[0041] It should be noted that the composition and ratio of the smoke-generating agent in the multiple aerosol generating capsules 104 may be the same or different, and this embodiment of the present invention does not limit this.

[0042] In some embodiments, the core material of the aerosol generating capsule 104 may further include an oily formulation and a structural agent; the structural agent includes cellulose and / or cellulose derivatives, low molecular weight lipids, and surfactants, and the core material may be a paste, a colloid, or a solid-liquid mixture. The combination of cellulose and / or cellulose derivatives and low molecular weight lipids facilitates the formation of a network structure in the oily formulation that promotes the dispersion and fixation of propylene glycol and glycerol. The surfactants contribute to the formation of an oil film between the core material and the shell of the aerosol generating capsule 104, thereby facilitating the encapsulation of the core material by the shell. The core material formed from propylene glycol and glycerol, the oily formulation, and the structural agent is in the form of a paste, a colloid, or a solid-liquid mixture at room temperature (25°C), which facilitates the stable encapsulation of the core material by the shell of the aerosol generating capsule 104.

[0043] It should be clarified that the use of oily agents and structural agents in the core material is only one specific means of coating the smoke-generating agent and other components. In order to coat the smoke-generating agent and other components in the core material, known coating methods in the existing technology can also be used, such as coating and spheroidizing method, freeze coating method, coagulation method, etc.

[0044] In some embodiments, the shell material of the aerosol generating capsule 104 may be a thermosetting resin, such as epoxy resin cured under a photoinitiator.

[0045] In some embodiments, the shell material of the aerosol generating capsule 104 may include, but is not limited to, any one or more of the following colloidal substances: plant gums, animal gums, microbial gums, starch, starch modifiers, etc. The animal gums may be, for example, gelatin, fish glue, or chitosan, etc., and the plant gums may be, for example, carrageenan, sodium alginate, gellan gum, or tamarind gum, etc.

[0046] To facilitate shaping during processing, the shell material may further include a curing agent. The curing agent may be a polyol, specifically glycerol or sorbitol.

[0047] In some embodiments, the shell material may further include a reinforcing agent, such as a metal salt, specifically calcium chloride, potassium chloride, calcium carbonate, calcium phosphate, or calcium dihydrogen phosphate.

[0048] The thickness of the shell of the aerosol generating capsule 104 can be designed to be 30-150 μm, for example, 50 μm, 80 μm, 100 μm, 120 μm, 140 μm, etc.

[0049] In one embodiment of preparing aerosol-generating capsules 104, raw materials comprising propylene glycol and glycerin, an oily preparation, and a structuring agent are mixed to obtain a core material; a coating liquid is prepared using raw materials comprising a colloidal substance, a curing agent, and water; and then the coating liquid is used to coat the core material to prepare the aerosol-generating capsule. The method of preparing capsules by coating the core material with the coating liquid can employ some existing encapsulation methods, such as concentric tube dripping.

[0050] The shell of the aerosol-generating capsule 104 can rupture at a certain heating temperature, releasing the core material to generate aerosols. The release temperature of the aerosol-generating capsule 104 is typically lower than the smoking temperature of reconstituted tobacco leaves or shredded tobacco containing smoking agents such as glycerol or propylene glycol. In some embodiments, the heating release temperature of the aerosol-generating product can be 180–300°C; in other embodiments, the heating release temperature can be 200–250°C, for example, 230°C, 240°C, etc. Compared to existing HNB products, the aerosol-generating product provided in this embodiment of the invention can reduce the waiting time for heating to smoking. The amount of aerosol released by the aerosol-generating capsule 104 will vary depending on the heating temperature.

[0051] Furthermore, as the heating temperature continues to rise, the amount of aerosol released from the aerosol generating capsule 104 gradually increases. Moreover, when a certain temperature is reached, such as 300°C, if other aerosol-releasing materials are mixed in, these materials, excluding the aerosol generating capsule 104, also begin to produce vapor, further enhancing the user's vaping experience. Additionally, flavorings and other ingredients can be added to the mixed aerosol-releasing materials to enrich the aerosol flavor and better meet the diverse vaping preferences of different users.

[0052] In some embodiments, to enhance the flavor profile, one or more excipient capsules may be added to the aerosol matrix section 101. That is, the aerosol matrix section 101 includes the aforementioned aerosol-generating capsule 104 and the excipient capsules. In specific implementations, the excipient capsules may include any one or more of the following: flavor capsules, extract capsules, nicotine capsules, nicotine salt capsules, etc. In some embodiments, multiple ingredients may be mixed together and placed in the same excipient capsule; this is not limited in this embodiment of the invention.

[0053] In some embodiments, the volume ratio of the excipient capsules in the aerosol generating matrix section 101 to the aerosol generating capsules 104 can be 10:1 to 1:10, so as to better meet the personalized needs of different users for the smoking experience.

[0054] In specific implementations, the shell material, particle size, and shape of the excipient capsules may be the same as or different from the shell material, particle size, and shape of the aerosol generating capsules 104; this embodiment of the invention does not limit this. Furthermore, the distribution of the excipient capsules and the aerosol generating capsules 104 within the aerosol generating matrix section 101 may be uniform or non-uniform; this embodiment of the invention does not limit this.

[0055] like Figure 1 As shown, in some embodiments, a seal 105 may be provided at one end of the aerosol generating matrix section 101 near the end of the aerosol generating article 10. Additionally, the aerosol generating article 1 may also include: a limiting member 102, and / or a filter section 103.

[0056] The limiting member 102 is adjacent to the end of the aerosol generating matrix section 101 that is away from the end of the aerosol generating product 10, and the filter section 103 may be adjacent to or separated from the limiting member 102 by a certain distance.

[0057] In other embodiments, the limiting member 102 or the filter section 103 may not be provided. For example, the filter section 103 may be directly adjacent to the end of the aerosol generating matrix section 101 that is away from the end of the aerosol generating product 10. In this structural design, the filter section 103 can both filter the smoke and block the aerosol generating capsule 104 to prevent it from leaking out.

[0058] In some embodiments, such as Figure 1 As shown, the seal 105 can be a cellulose acetate rod or a cotton swab, which is used to seal one end of the aerosol generating matrix section 101 near the end of the aerosol generating product 10.

[0059] In some embodiments, the seal 105 may also be paper, non-woven fabric, woven fabric, or a thermally conductive material, which can be directly adhered to one end face of the aerosol generating matrix section 101. The thermally conductive material may specifically be metal foil, which can increase thermal conductivity and reduce the heating waiting time during suction. Except in specific embodiments, the seal is generally breathable or has vents to ensure that airflow can enter the aerosol generating product.

[0060] In some embodiments, the limiting member 102 can be a prefabricated part with through holes, or a sheet roll, etc. The limiting member can be made of, but is not limited to, any of the following: plant fiber, resin, metal, etc. The through holes can reduce suction resistance and prevent the aerosol-generating capsule 104 from passing through. The roll can be made of, but is not limited to, any of the following: paper, resin sheet (such as polylactic acid sheet), or metal sheet, etc.

[0061] The limiting component 102 can not only limit the aerosol generating capsule 104 to prevent it from detaching from the aerosol generating matrix section 101, but also cool the smoke when necessary to prevent the flue gas inlet temperature from being too high.

[0062] In some embodiments, the filter section 103 may include one or more filter components. The plurality of filter components may be connected sequentially along the axial or radial direction of the filter section. The filter components may be, for example, solid, hollow, or porous filter rods, etc., and this embodiment of the invention does not limit the specific type. The filter rod may be formed from one or more fibers.

[0063] In practice, the aforementioned aerosol generating matrix section 101, limiting member 102, and filter section 103 can be enclosed in the same tube, and the tube can be made of paper or the like.

[0064] The length of the tube can be designed to be 30–84 mm, specifically 40 mm, 60 mm, 80 mm, etc. The diameter of the tube can be 3.0–10.0 mm, specifically 5.0 mm, 7.0 mm, 9.0 mm, etc.

[0065] In some embodiments, a heat-conducting layer may be provided on the inner surface of the tube corresponding to the section of the aerosol generation matrix section 101 to increase thermal conductivity and reduce the heating waiting time during suction.

[0066] In some embodiments, a heat-conducting layer may be provided on the entire inner surface of the tube to facilitate manufacturing and improve the flame-retardant effect.

[0067] The heat-conducting layer can be made of materials such as aluminum foil, which not only conducts heat but also acts as a flame retardant.

[0068] The aerosol-generating products provided in this invention are highly versatile and can be adapted to various heating smoke appliances, such as needle-type heating smoke appliances, plate-type ceramic heating plate smoke appliances, air-heated smoke appliances, and microwave-heated smoke appliances.

[0069] In some embodiments, a sensor may also be provided in the aerosol generating matrix section 101 to adapt it to the electromagnetic induction heating appliance.

[0070] The aerosol-generating capsules used in the embodiments of the present invention can be prepared by a variety of methods, such as one of the following methods.

[0071] Heat 40 parts by weight of sunflower seed oil to 100°C, and while stirring, add 7.1 parts by weight of ethyl cellulose, 1.4 parts by weight of beeswax, and 2.1 parts by weight of palm wax. Dissolve and mix evenly, cool to 60°C, and add 24 parts by weight of propylene glycol, 16 parts by weight of glycerol, 2.4 parts by weight of surfactant (prepared from Tween 80 and glyceryl monooleate in a weight ratio of 1:9), 5 parts by weight of mango flavoring, and 2 parts by weight of nicotine salt. Stir evenly to complete the preparation of the core material.

[0072] Add 5 parts by weight of carrageenan and 3 parts by weight of gellan gum to 82 parts by weight of purified water, and heat while stirring at a temperature of 60-90°C to form a homogeneous solution. Add 10 parts by weight of glycerol and stir until homogeneous to prepare the film solution.

[0073] Using a concentric dropper, the core material (inner layer) and film liquid are dripped into the cooling liquid (MCT) while the temperature is controlled at 10℃~25℃ to form wet capsules. The capsules are then stored at -10℃~10℃ for 10 hours and dried at 20~30℃ and 20%~50% humidity to obtain capsule products with a particle size of 2mm and a wall thickness of 70μm.

[0074] When manufacturing the aerosol-generating products provided in the embodiments of the present invention, products with different tastes and inhalation effects can be made by adjusting parameters such as the length of the aerosol-generating matrix segment, the aerosol-generating capsule arrangement density, and the particle size, so as to meet the needs and experiences of different smokers.

[0075] To further verify the vaping experience, different vaping devices were used at different heating temperatures to compare the amount of vapor and sensory evaluation. The specific tests are as follows:

[0076] The aerosol-generated product sample has a length of 45 mm, an aerosol-generating matrix section length of 10 mm, an aerosol-generating capsule particle size of 1.5–2 mm, and a filling height ratio of 80% (the filling height ratio is the ratio of the static height of the aerosol-generating capsules stacked after the aerosol-generating product is upright to the length of the aerosol-generating matrix section).

[0077] Based on the above sample parameters, heating tests were conducted on the samples at different temperatures using both air-heated and center-heated smoke machines. The test results are shown in Table 1 below.

[0078] Table 1

[0079]

[0080] Scoring criteria: Smoke volume, aroma, stability, satisfaction, aftertaste, and oral residue. The best score for any single item is 10 points, and the worst score is 0 points.

[0081] Based on the above test results, it can be seen that aerosol-generated capsules can be heated and released at a lower temperature, providing a good inhalation experience.

[0082] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
