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 matrix, but most related technologies simply use capsules as a supplement to tobacco materials. Some patents also mention using pure capsules directly as aerosol-generating material and placing them in the aerosol-generating matrix section; however, these technologies all use a single capsule and need to address the problem of core material leakage after capsule rupture, for example, by using an absorbent pad to absorb the capsule core material. It is evident that the relevant technical literature has not explicitly proposed an optimized cigarette tube structure using aerosol-generating capsules, nor has it solved a series of technical problems related to directly using capsules as aerosol-generating materials. Summary of the Invention

[0006] Therefore, this invention provides an HNB product, namely an aerosol generating product, to increase smoke production, reduce heating release temperature, reduce draw resistance, and improve the inhalation experience.

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

[0008] An aerosol generating product includes an aerosol generating matrix section, which comprises an aerosol generating capsule. The aerosol generating matrix section has channels on a corresponding tube body to allow air to flow from the outside to the inside of the tube. By providing channels on the tube body corresponding to the aerosol generating matrix section, an additional airflow path is provided, which can reduce suction resistance. During the heating process of the aerosol generating capsule, the capsule closest to the heat source ruptures first. Capsule rupture may lead to collapse and accumulation, and combined with the adhesion of the core liquid, this may increase the suction resistance at the sealed end of the tube body. Providing channels on the tube body can also compensate for possible airflow loss, thereby reducing suction resistance. Furthermore, the additional airflow path also facilitates heat entry into the tube body from the periphery, improving heating efficiency.

[0009] Optionally or preferably, one end of the aerosol generating product corresponding to the aerosol generating matrix segment is sealed. The distance between the channel and the sealed end is greater than 1 mm and less than 8 mm, preferably greater than 3 mm and less than 5 mm. The distance between the channel and the sealed end can be determined according to the height of the aerosol generating matrix segment, preferably such that the airflow through the channel on the tube can flow through the aerosol generating capsule.

[0010] Optionally or preferably, the channels may be multiple.

[0011] Optionally or preferably, the number of channels is greater than or equal to four.

[0012] Optionally or preferably, the channels are distributed circumferentially along the tube body. Circumferential distribution, especially uniform distribution, can make full use of the heat around the tube body.

[0013] Optionally or preferably, the channels are distributed in multiple rows or columns along the circumference of the tube.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] The aerosol generating product provided in this invention includes an aerosol generating capsule in the aerosol generating matrix section. Compared with existing products using reconstituted tobacco leaves or tobacco shreds as core materials, it can achieve uniform and sufficient smoke release at a lower heating temperature, thereby effectively reducing energy consumption and the release of harmful substances while improving the vaping experience. By setting channels on the tube body corresponding to the aerosol generating matrix section, the air intake in the tube can be increased, which can reduce the suction resistance and further improve the vaping experience.

[0030] 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.

[0031] To address the issues of low smoke production 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-generating product. This product utilizes an aerosol-generating capsule to increase smoke production. Furthermore, the tube body corresponding to the aerosol-generating matrix section has channels, which can effectively enhance the inhalation experience.

[0032] Simultaneously refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of a structure of an aerosol-generated product provided in an embodiment of the present invention; Figure 2 and Figure 3 yes Figure 1 The diagram shows two different distributions of the channels on the tube of the aerosol-generated product.

[0033] The aerosol generating article of this example includes a tube body, which includes an aerosol generating matrix segment 101. The aerosol generating matrix segment 101 includes an aerosol generating capsule 104. One or more channels 106 are provided on the tube body corresponding to the aerosol generating matrix segment 101, for example, the number of channels 106 is greater than or equal to 4, so that air can flow from the outside of the tube to the inside of the tube through the channels 106.

[0034] The aerosol generating article provided in this embodiment of the invention includes an aerosol generating capsule 104 in the aerosol generating matrix section 101. Compared to existing products using reconstituted tobacco leaves or shredded tobacco as core materials, it can achieve uniform and sufficient smoke release at a lower heating temperature. Furthermore, by providing channels 106 on the tube body corresponding to the aerosol generating matrix section, suction resistance can be reduced during heating, effectively improving the vaping experience. In addition, this structure is more suitable for methods such as hot air convection heating, peripheral resistance heating, and peripheral current heating, which facilitates heat transfer.

[0035] In practice, multiple channels 106 can be distributed on part or all of the aerosol generation matrix section 101 on the tube body, and can be evenly or non-uniformly distributed along the circumference of the tube body. Even distribution along the circumference of the tube body can make the air flowing into the tube more uniform, making the suction feel smoother.

[0036] In some embodiments, such as Figure 2 As shown, multiple channels 106 are evenly distributed along the circumference of the tube body and are distributed in a circle.

[0037] In some embodiments, the plurality of channels 106 may be distributed in multiple rings along the circumference of the tube body, such as Figure 3 As shown, multiple channels 106 are distributed in two concentric circles along the circumference of the tube, and the two concentric circles are parallel to each other. Of course, the distribution of channels 106 along the circumference of the tube can be implemented in an irregular manner, and whether they are parallel or aligned is not limited in this invention.

[0038] In specific implementation, the area and shape of the multiple channels 106 may be the same or different. Their shapes may be, for example, circular, elliptical, square, rhomboid, etc. The embodiments of the present invention do not limit this.

[0039] The length of the aerosol generating product tube can be designed to be 30–84 mm, specifically 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc. The diameter of the tube can be 3.0–10.0 mm, specifically 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, etc. The length of the aerosol generating matrix section 101 can be less than or equal to the length of the tube, for example, it can be 10%–60% of the total tube length.

[0040] The tube can be made of materials such as paper.

[0041] The aerosol generating capsule 104 within the aerosol generating matrix section 101 can be single or multiple. Compared to the structure of a single aerosol generating capsule, multiple aerosol generating capsules can make the smoke more persistent when heated.

[0042] The aerosol generating matrix segment 101 may contain only the aforementioned aerosol generating capsule 104, or it may contain both the aforementioned aerosol generating capsule 104 and other aerosol generating materials. This embodiment of the invention is not limited in this respect.

[0043] The aerosol generating capsule 104 can be tightly packed or loosely packed within the aerosol generating matrix section 101. Tight packing, for example, means that the vertical, naturally filled height of the aerosol generating capsule within the aerosol generating matrix section is equal to the length of the aerosol generating matrix section. Loose packing, also known as loose filling, means that the vertical, naturally filled height of the aerosol generating capsule within the aerosol generating matrix section is less than the length of the aerosol generating matrix section. Compared to tight packing, loose packing of the aerosol generating capsule within the aerosol generating matrix section effectively reduces suction resistance during aspiration and also facilitates the insertion of the heating element during center heating.

[0044] 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 the shape. For example, in some non-limiting embodiments, the particle size of the aerosol generating capsule 104 can be designed to be 1-3 mm. In some specific embodiments, the particle size of the aerosol generating capsule 104 can be 1.5-2.5 mm, for example, 2.0 mm.

[0045] 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 0.4 g, preferably 0.1 to 0.3 g.

[0046] 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%.

[0047] 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 some embodiments, the smoke-generating agent comprises propylene glycol and glycerin, wherein propylene glycol and glycerin account for 4 to 60 wt% of the core material, preferably 15 to 50 wt%.

[0048] 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.

[0049] Glycerin produces a large amount of smoke with a sweet taste. Propylene glycol produces smoke with a weaker visual effect but 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 can be chosen in the range of 2:8 to 8:2.

[0050] 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. The composition and ratio of the smoke-generating agent within multiple aerosol-generating capsules 104 may be the same or different, and this embodiment of the invention does not limit this. Extracts may be animal extracts or plant extracts, such as musk, ambergris, tea extract, monk fruit extract, etc., and the flavor can be adjusted as needed.

[0051] In some embodiments, the core material of the aerosol generating capsule 104 may further include: an oily preparation and a structural agent; the core material formed by propylene glycol and glycerin, the oily preparation and the structural agent is in the form of a paste, a colloid or a solid-liquid mixture at room temperature (25°C), which can help achieve stable encapsulation of the core material by the shell of the aerosol generating capsule 104.

[0052] 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 encapsulation methods in the existing technology can also be used, such as photocuring dripping method, coating and spheroidizing method, cryo-coating method, coagulation method, etc.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] The thickness of the shell of the aerosol generating capsule 104 can be designed to be, for example, 30–150 μm.

[0057] The shell of the aerosol-generating capsule 104 can rupture at a certain heating temperature, releasing the core material to generate aerosol. 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 of the aerosol-generating product can be 200–250°C. Therefore, compared to existing HNB products, the aerosol-generating product provided by this invention can reduce the waiting time for heating to produce smoke.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Simultaneously refer to Figure 1 and Figure 2 In some embodiments, the aerosol generating article may further include a limiting member 102 and / or a filter section 103.

[0062] One end of the limiting member 102 is adjacent to the aerosol generating matrix section 101 along the airflow direction, and is used to restrict the passage of aerosol generating capsules 104 in the aerosol generating matrix section 101. The other end of the limiting member 102 may be adjacent to or at a certain distance from the filter section 103.

[0063] 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.

[0064] 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.

[0065] The filter section 103 is located at the other end of the tube and can be adjacent to or separated from the limiting member 102 by a certain distance.

[0066] In some embodiments, the filter section 103 may also be directly adjacent to the other end of the aerosol generating matrix section 101, that is, the limiting member 102 may not be provided. In this structure, the filter section 103 can not only filter the smoke, but also limit the aerosol generating capsule 104 in the aerosol generating matrix section 101 to prevent it from falling out of the aerosol generating matrix section 101.

[0067] In the above embodiments, the filter section 103 may include one or more filter components. The plurality of filter components are sequentially connected 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 of filter rod. The filter rod may be formed from one or more fibers.

[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, a seal 105 is provided at one end of the aerosol generating matrix section 101 near the tube body. The seal 105 can be paper, non-woven fabric, woven fabric, etc., and can be directly adhered to one end face of the aerosol generating matrix section.

[0069] like Figure 4 and Figure 5 The diagram shown is another structural schematic of the aerosol-generated product provided in an embodiment of the present invention.

[0070] In this example, the aerosol generating article includes a tube body, which includes an aerosol generating matrix section 201, a limiting member 202, and a filter section 203. The aerosol generating matrix section 201 includes an aerosol generating capsule 204, and one or more channels are provided on the tube body corresponding to the aerosol generating matrix section 201.

[0071] The aforementioned aerosol generating matrix section 201, limiting member 202, filter section 203, and aerosol generating capsule 204 and Figure 1 The aerosol generating matrix section 101, limiting member 102, filtering section 103, and aerosol generating capsule 104 are similar, and can be referred to the description in the previous embodiments, which will not be repeated here.

[0072] Figure 4 In the illustrated embodiment, a seal 205 is provided at one end of the aerosol generating matrix section 201 near the tube body. The seal 205 is made of a thermally conductive material, such as a metal foil like aluminum foil or tin foil, which increases thermal conductivity and reduces the heating waiting time during suction. Except in specific embodiments, the seal 205 is generally permeable or has vents to ensure that airflow can enter the aerosol generating product. For example, the seal 205 may have multiple vents.

[0073] In other embodiments, the encapsulation structure may also be a cellulose acetate rod or a cotton swab, which is used to seal one end of the aerosol generating matrix section near the tube end.

[0074] In some embodiments, a thermally conductive layer may be provided on the inner surface of the tube corresponding to the aerosol generation matrix section to increase thermal conductivity and reduce the heating waiting time during suction.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The aerosol-generating products provided in this embodiment of the invention can have different processing steps depending on their structure.

[0082] For example, one processing method is as follows: a paper tube with an outer diameter of 9.0 mm, a length of 45 mm, and a sealed bottom is made, and a hole is made in an area 10 mm away from the seal. 0.2 g of aerosol capsules are filled from the open end, and then a 28 mm hollow cellulose acetate filter rod is inserted.

[0083] For example, one processing method is as follows: a paper tube with an outer diameter of 9.0 mm and a length of 45 mm is made without sealing at both ends. A hole is made in the area 10 mm away from the seal. Then, a 7 mm cellulose acetate rod, a 0.2 g aerosol generating capsule, and a 23 mm hollow cellulose acetate rod are sequentially filled in.

[0084] 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.

[0085] In some embodiments, a sensor may also be provided within the aforementioned aerosol generation matrix section to adapt it to electromagnetic induction heating appliances.

[0086] 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.

[0087] To further verify the suction experience of products with different design parameters, a comparative test was conducted with and without channels on the tube corresponding to the aerosol generation matrix section, as detailed below:

[0088] Both groups of aerosol generating products use the same structural design parameters. The aerosol generating matrix section is filled with aerosol generating capsules of the same particle size and number. The filling height ratio of the aerosol generating capsules (the ratio of the static height of the stacked aerosol generating capsules after the aerosol generating product is vertical to the length of the aerosol generating matrix section) is the same. The difference is that the first group of aerosol generating products does not have channels on the tube body corresponding to the aerosol generating matrix section, while the second group of aerosol generating products has 21 channels with a diameter of 0.08 mm on the tube body corresponding to the aerosol generating matrix section at a distance of 5 mm from the port.

[0089] The absorption resistance and sensory evaluation of the two groups of aerosol-generated products were conducted, and the test data are shown in Table 1 below:

[0090] Table 1

[0091]

[0092] In the above tests, the best score for each of the following categories—aroma quantity, aroma quality, stability, satisfaction, aftertaste, and oral residue—is 10, and the worst score is 0.

[0093] The test results above show that by setting channels on the tube body corresponding to the aerosol generation matrix section, the aerosol generation product can achieve lower suction resistance, stronger smoke volume, and a better suction experience during inhalation.

[0094] 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.
