Description

Technical Field

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

[0002] Aerosol generating products are used to generate aerosols for users to inhale. They typically have a medium section and a functional section, and are formed by wrapping with shaping paper. The medium section contains an aerosol generating medium, which can generate aerosols under specific conditions such as heating. The aerosols are then cooled and / or filtered by the functional section before being inhaled by the user.

[0003] When using aerosol-generating products, the poor impermeability of the forming paper allows aerosols in the functional sections to easily seep through, causing aerosol loss and moisture absorption of the forming paper. Furthermore, during the intervals between aerosol inhalations, the aerosol-generating medium continues to release aerosols. At this time, aerosols tend to accumulate in the functional sections and seep through the forming paper, forming side-flow fumes, which also contributes to aerosol loss. These issues result in a poor user experience with aerosol-generating products. Summary of the Invention

[0004] In view of this, the present invention provides an aerosol generating article to solve the problem of poor user experience of existing aerosol generating articles.

[0005] To solve the above problems, the technical solution of the present invention is implemented as follows:

[0006] An aerosol generating article includes: a medium portion having an aerosol generating medium capable of generating aerosols; a functional component disposed at one end of the medium portion; and an encapsulation layer including at least one first encapsulation layer composed of a regenerated cellulose membrane, wherein the first encapsulation layer at least covers the functional component; wherein the basis weight of the first encapsulation layer is 15-40 g / m³. 2 .

[0007] In some embodiments, the thickness of the first wrapping layer is 10-50 μm.

[0008] In some embodiments, the air permeability of the first wrapping layer is no greater than 20 COS units.

[0009] In some embodiments, the first wrapping layer also covers the medium portion.

[0010] In some embodiments, the wrapping layer further includes at least one second wrapping layer, which is stacked on the side of the first wrapping layer opposite to the functional component and at least covers the functional component.

[0011] In some embodiments, an adhesive layer is provided between the first wrapping layer and the second wrapping layer to fix the first wrapping layer and the second wrapping layer.

[0012] In some embodiments, the total basis weight of the encapsulation layer is 25-70 g / m³. 2 .

[0013] In some embodiments, the total thickness of the encapsulation layer is 50-150 μm.

[0014] In some embodiments, the total air permeability of the wrapping layer is no greater than 20 COS units.

[0015] In some embodiments, the wrapping layer includes one first wrapping layer and two second wrapping layers, with the two second wrapping layers respectively stacked on both sides of the first wrapping layer.

[0016] In some embodiments, the wrapping layer includes multiple first wrapping layers, each of the first wrapping layers being stacked sequentially, and at least one second wrapping layer being stacked outside the outermost first wrapping layer.

[0017] In some embodiments, the functional component includes: a cooling element connected to the medium portion; and a filter element connected to the cooling element; wherein the first wrapping layer covers at least the cooling element and the filter element.

[0018] The aerosol generating article provided in this embodiment of the invention includes a medium, a functional component, and a coating layer. The coating layer includes at least one first coating layer composed of a regenerated cellulose membrane. The first coating layer at least covers the functional component, and the basis weight of the first coating layer is 15-40 g / m³. 2 In this way, the coating layer utilizes the excellent anti-leakage properties of the regenerated cellulose membrane, effectively reducing the problem of moisture leakage into the coating layer, and also reducing aerosol leakage at functional components and the generation of side-flow fumes, thus improving the utilization rate of aerosols. Furthermore, by controlling the basis weight range of the first coating layer, it not only possesses sufficient strength to meet the requirements of the aerosol-generated product forming process, but also produces less paper odor when heated, reducing the impact of paper odor on aerosol quality. Through the above design, the aerosol-generated product provided by the embodiments of the present invention offers a better user experience. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0031] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0033] Aerosol generating products are used to generate aerosols for users to inhale. They typically consist of a medium section and a functional section, which are wrapped in forming paper to form a specific shape, such as a cylinder. The medium section stores an aerosol generating medium, which can generate aerosols under specific conditions such as heating or ignition. After being processed by the functional section, the aerosols are ready for users to inhale.

[0034] Aerosol generating media typically exist in two forms: solid and liquid. Traditional aerosol generating products usually store a solid form of aerosol generating medium and generate aerosols by igniting the medium. The forming paper used in such aerosol generating products (hereinafter referred to as ignition-type products) is usually a single layer of paper, and this layer of paper is usually manufactured in accordance with the industry standard "Filter Rod Forming Paper (YC / T208-2006)".

[0035] With the development of related technologies, a type of aerosol generating product (hereinafter referred to as a heated product) has emerged on the market that generates aerosols by heating a medium. Its main difference from traditional ignition-type products is that it does not require an open flame to ignite the medium. When using this type of heated product, a matching heating device is typically used to heat the medium in the medium section, causing the medium to release aerosols. After processing in the functional section, the aerosols are ready for the user to inhale. For heated products, the forming paper serves a similar function to that used in traditional ignition-type products, acting as a wrapping and shaping agent. Furthermore, the forming paper used in heated products is typically manufactured using the same process as that used in ignition-type products.

[0036] However, because heated and ignition-type products release aerosols differently, their functional section structures also differ. Therefore, when the forming paper used in ignition-type products is applied to heated products, significant problems arise. Specifically, the functional sections of ignition-type products typically only have a filter structure, while the functional sections of heated products usually also have cooling and support structures, making the functional section structure of heated products more complex and functionally designed to cool the aerosols. Furthermore, some heated products contain flavorings such as flavoring capsules and fragrances, which are volatile liquids. Therefore, condensation of aerosols and flavorings is more likely to occur in the functional sections of heated products. This condensed aerosols and flavorings seep through the forming paper, causing aerosol and flavoring loss, and moisture absorption of the forming paper. On the other hand, during the intervals between the user's aerosol suction, the aerosol generating medium continues to be heated and release aerosols. At this time, without suction, the aerosol tends to stagnate in the functional section and seep through the forming paper, forming sideflow fumes, which also causes aerosol loss. These issues affect the product's user experience.

[0037] To solve the above problems, such as Figure 1 As shown, this embodiment of the invention provides an aerosol generating article 1, which is a heated article and includes a medium portion 11, a functional component 12, and a coating layer 13. The medium portion 11 has an aerosol generating medium capable of generating aerosols. The functional component 12 is disposed at one end of the medium portion 11 to process the aerosols. The coating layer 13 includes at least one first coating layer 131 made of regenerated cellulose membrane, which at least covers the functional component 12, and the basis weight of the first coating layer 131 is 15-40 g / m³. 2 .

[0038] Specifically, the aerosol generating medium of the medium section 11 is typically a solid medium that releases aerosols upon heating to a certain degree without the need for open flame ignition. The aerosols generated by the medium section 11 are processed by the functional component 12 and then discharged to the outside environment for user absorption. The processing of the aerosols by the functional component 12 typically includes lowering the aerosol temperature to control the temperature at the time of aerosol output within a suitable range. Of course, depending on the design, the functional component 12 can also perform other processing on the aerosols to further improve their quality.

[0039] Specifically, the first coating layer 131 is composed of a regenerated cellulose membrane, which is a thin film structure with high cellulose crystallinity made from natural fiber materials through a specific process. Optionally, the fiber material used to make the regenerated cellulose membrane can be one or more combinations of fiber materials such as hemp pulp fiber, softwood pulp fiber, hardwood fiber, cotton pulp fiber, and straw pulp fiber, and the fiber material has a high cellulose crystallinity after processing, for example, not less than 85%. The manufacturing process of the regenerated cellulose membrane typically includes: alkalizing the raw material to obtain alkali cellulose, esterifying it to obtain cellulose xanthate, dissolving it to obtain cellulose viscose, extruding it through a film stretching machine, and drying it to form a film, which is the regenerated cellulose membrane. By using the above-mentioned fiber materials and manufacturing process, the first coating layer 131 composed of a regenerated cellulose membrane can be obtained. This first coating layer 131 has strong anti-permeability properties and is not prone to moisture absorption and leakage problems.

[0040] Optionally, the wrapping layer 13 may consist of only one first wrapping layer 131, thereby simplifying the manufacturing process and reducing costs while meeting the requirements for impermeability. Of course, the wrapping layer 13 may also include multiple first wrapping layers 131 to further enhance its impermeability. In some embodiments, the wrapping layer 13 may also include other material layers to improve its aesthetics or other related properties. It is understood that the design of the wrapping layer 13 is highly flexible; it only needs to ensure that the first wrapping layer 131 at least covers the functional component 12, thereby enhancing impermeability at least at the functional component 12 where aerosol condensation and sideflow gas generation are likely to occur.

[0041] In addition to employing a coating layer 13 comprising at least one first coating layer 131, this embodiment of the invention further employs a design where the basis weight of the first coating layer 131 is 15-40 g / m³. 2 Alternatively, in some embodiments, the basis weight of the first wrapping layer 131 can be designed to be 20-30 g / m³. 2 Thus, the first coating layer 131 possesses good structural strength, meeting the strength requirements of the aerosol-generated product 1 during the molding process. Specifically, the assembly and molding of the aerosol-generated product 1 is typically achieved using a specialized molding machine, which stretches and rolls the coating layer 13 to complete the coating operation. The basis weight of the first coating layer 131 is designed to be no less than 15 g / m³. 2 Therefore, the wrapping layer 13 is less prone to tearing or obvious creases during stretching and curling, ensuring reliable wrapping and good product appearance integrity. Furthermore, the basis weight of the first wrapping layer 131 is no greater than 40 g / m². 2This can effectively reduce the paper odor generated by the first wrapping layer 131 when heated, thereby reducing the impact of paper odor on aerosol quality and improving the cleanliness of the aerosol.

[0042] The aerosol generating article 1 provided in this embodiment of the invention includes a medium portion 11, a functional component 12, and a coating layer 13. The coating layer 13 includes at least one first coating layer 131 made of regenerated cellulose membrane. The first coating layer 131 covers at least the functional component 12, and the basis weight of the first coating layer 131 is designed to be 15-40 g / m³. 2 In this way, the coating layer 13 utilizes the good impermeability of the regenerated cellulose membrane. When the aerosol generated by the medium section 11 passes through the functional component 12, it is not easy to leak through the first coating layer 131, effectively reducing the problem of aerosol leakage and the generation of side-flowing fumes, improving the utilization rate of aerosols, and also reducing the problem of the coating layer 13 becoming damp and affecting the appearance and user experience. At the same time, since the regenerated cellulose membrane is a biodegradable material, it can reduce the environmental pollution caused by the coating layer 13, which is in line with the concept of green environmental protection. In addition, by controlling the weight range of the first coating layer 131, this embodiment of the invention not only gives the first coating layer 131 good structural strength, making it less prone to tearing or obvious creases in the forming process of the aerosol-generated product 1, but also reduces the papery odor generated by the first coating layer 131 when heated, improves the cleanliness of the aerosol, and improves the taste of the aerosol. Through the above design, the aerosol-generated product 1 can provide a better user experience.

[0043] In some embodiments, the thickness of a single layer of the first wrapping layer 131 is 10-50 μm. Optionally, the thickness of a single layer of the first wrapping layer 131 can be set to 20-30 μm. This design provides a moderate thickness for the first wrapping layer 131, achieving both good leak-proof performance and structural strength. Furthermore, the thickness of the first wrapping layer 131 is not excessive, resulting in less paper odor generated when heated, and also helps control the manufacturing cost of the wrapping layer 13, improving material utilization. It is understood that when the wrapping layer 13 comprises multiple layers of the first wrapping layer 131, the thickness of each first wrapping layer 131 can be set within the aforementioned range, and the thicknesses of each layer can be stacked.

[0044] Optionally, the thickness of the first coating layer 131 can be uniform or non-uniform. When the thickness of the first coating layer 131 is uniform, it facilitates manufacturing, and the consistency of the thickness is easily controlled. Alternatively, the thickness of certain portions of the first coating layer 131 can be increased. For example, in some embodiments, the portion of the first coating layer 131 corresponding to a local structure of the functional component 12 can be thickened. This local structure can be a structure in the functional component 12 used to cool the aerosol. By increasing the thickness of the first coating layer 131 at this structure, the anti-leakage effect can be enhanced at locations prone to condensation and leakage, effectively preventing leakage of substances generated by condensation. In other embodiments, the first coating layer 131 can also be thickened at the connection points between the functional component 12 and the medium segment 11, and / or at the connections between adjacent components within the functional component 12. This enhances the anti-leakage effect at the structural connections.

[0045] When using the above-mentioned thickening design, the thickness change between the thickened part and other parts on the first wrapping layer 131 can be gradual or abrupt. It is only necessary to design the corresponding shape of other related structures of the aerosol generating product 1 so that the wrapping layer 13 has a relatively uniform shape when it is wrapped.

[0046] In some embodiments, the air permeability of the first wrapping layer 131 is no greater than 20 COSTER units. A COSTER unit is a unit of air permeability for sheet materials, corresponding to 1 cm of material permeability under a measurement pressure of 1 kPa. 2 Airflow rate per square meter of surface area (in cm²) 3 / min), where the measured pressure is the pressure difference between two surfaces of the material. That is, the unit corresponding to the Costa unit is cubic centimeters per minute per square centimeter (cm²) at a measured pressure of 1 kPa. 3 ·min -1 ·cm -2 Optionally, the air permeability of the first wrapping layer 131 can be set to no more than 15 COS units, or no more than 10 COS units, thereby further reducing the air permeability level of the first wrapping layer 131. By controlling the air permeability of the first wrapping layer 131 within the above range, the moisture-proof and leak-proof performance of the first wrapping layer 131 can be better guaranteed, improving the user experience of the aerosol-generated product 1.

[0047] In some embodiments, such as Figure 1As shown, the first coating layer 131 also covers the medium portion 11, meaning that the first coating layer 131 can simultaneously cover the medium portion 11 and the functional component 12. With this design, the first coating layer 131 covers a larger area, providing a seepage-proof function for both the medium portion 11 and the functional component 12, further enhancing the seepage-proof performance of the aerosol-generating product 1, and also improving the overall strength of the coating layer 13.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the wrapping layer 13 further includes at least one second wrapping layer 132, which is stacked on the side of the first wrapping layer 131 facing away from the functional component 12 and at least covers the functional component 12. Specifically, the second wrapping layer 132 can cover at least part of the first wrapping layer 131 to improve the aesthetics of the product and further improve the waterproof performance of the wrapping layer 13.

[0049] Optionally, when the first wrapping layer 131 only covers the functional component 12, such as Figure 2 As shown, the second coating layer 132 can also cover the portion of the medium 11 and other parts not covered by the first coating layer 131, thereby forming the aerosol-generating product 1 into a complete whole. When the first coating layer 131 has already covered both the medium 11 and the functional component 12, such as... Figure 1 As shown, the second wrapping layer 132 can cover only the functional component 12 to conceal the related structure of the functional component 12 and part of the first wrapping layer 131, thereby improving aesthetics. Of course, the first wrapping layer 131 and the second wrapping layer 132 can also simultaneously cover the medium portion 11 and the functional component 12, such as... Figure 3 As shown, this design results in better overall aesthetics, and the first wrapping layer 131 and the second wrapping layer 132 can be set to have the same length, thus ensuring uniform length dimensions during processing and facilitating manufacturing.

[0050] Alternatively, in some implementations, such as Figure 4 As shown, the wrapping layer 13 may further include at least one third wrapping layer 133. By covering the medium portion 11 with the third wrapping layer 133, the first wrapping layer 131 and the second wrapping layer 132 may only cover the functional component 12. The design scheme of the wrapping layer 13 described above can be flexibly selected, as long as at least one of the first wrapping layer 131, the second wrapping layer 132 and the third wrapping layer 133 covers the medium portion 11.

[0051] Optionally, the second wrapping layer 132 can be paper made according to the industry standard "Filter Rod Forming Paper (YC / T208-2006)," or it can be made of materials that can be rolled and deformed, such as aluminum foil, tin foil, plastic film, or PLA (polylactic acid fiber). Optionally, the second wrapping layer 132 can be provided as a single layer or multiple layers. The material and thickness parameters of different second wrapping layers 132, or different parts of the same second wrapping layer 132, can be the same or different. It is understood that when the wrapping layer 13 includes a third wrapping layer 133, the arrangement of the third wrapping layer 133 is the same as that of the second wrapping layer 132, and the material and thickness parameters of the third wrapping layer 133 and the second wrapping layer 132 can also be the same or different. For example, as Figure 2 As shown, the third wrapping layer 133 used in the wrapping medium section 11 can have different materials and thicknesses compared to the second wrapping layer 132 used in the wrapping functional component 12, and can be flexibly designed according to needs.

[0052] In some embodiments, such as Figure 5 As shown, an adhesive layer 134 is provided between the first coating layer 131 and the second coating layer 132 to fix the first coating layer 131 and the second coating layer 132. Specifically, the adhesive layer 134 is formed of an adhesive material, and the first coating layer 131 and the second coating layer 132 are bonded and fixed through the adhesive layer 134, thereby forming a multi-layer composite structure coating layer 13. Optionally, the material of the adhesive layer 134 can be one or a combination of several of vinyl acetate-ethylene copolymer emulsion, vinyl acetate emulsion, and modified starch.

[0053] Of course, the first coating layer 131 and the second coating layer 132 can also be encapsulated separately and sequentially to encapsulate the structure of the aerosol-generated product 1 without being bonded together. For example, the first coating layer 131 can be encapsulated first, and then the second coating layer 132 can be encapsulated outside the first coating layer 131, which can also achieve the effect of encapsulation and shaping. Similarly, when the coating layer 13 includes a third coating layer 133, the third coating layer 133 can be bonded to the first coating layer 131 and to the second coating layer 132 through an adhesive layer 134, or no adhesive bonding may be used.

[0054] In some embodiments, the total weight of the encapsulation layer 13 is 25-70 g / m³. 2 Optionally, the total weight of the wrapping layer 13 can be set to 30-50 g / m³. 2 With this design, the total weight of the wrapping layer 13 can better meet the structural strength requirements, allowing the wrapping layer 13 to achieve a better wrapping effect through the forming machine. When using the forming machine for mass production, controlling the weight range of the wrapping layer 13 can also better ensure the consistency of product quality.

[0055] In some embodiments, the total thickness of the wrapping layer 13 is 50-150 μm. Optionally, the total thickness of the wrapping layer 13 can be set to 70-100 μm. The total thickness of the wrapping layer 13 refers to the sum of the thicknesses of each layer; that is, when the wrapping layer 13 is a multi-layered structure, the sum of the thicknesses of each layer is within the above range. With this design, the wrapping layer 13 has moderate structural strength and hardness, and also has good impermeability.

[0056] In some embodiments, the total air permeability of the wrapping layer 13 is no greater than 20 COS units. Optionally, the air permeability of the wrapping layer 13 can be set to no greater than 15 COS units, or even no greater than 10 COS units, thereby further reducing the air permeability level of the wrapping layer 13. By controlling the total air permeability of the wrapping layer 13 within the above range, the moisture-proof and leak-proof performance of the wrapping layer 13 can be better guaranteed, improving the user experience of the aerosol-generated product 1.

[0057] Optionally, the first wrapping layer 131 and the second wrapping layer 132 in the wrapping layer 13 can each be provided with one or more layers. For example, in one embodiment, such as Figure 6 As shown, the wrapping layer 13 may include a first wrapping layer 131 and two second wrapping layers 132. The two second wrapping layers 132 are respectively stacked on both sides of the first wrapping layer 131, and the two second wrapping layers 132 and the first wrapping layer 131 can be bonded and fixed together by adhesive layers 134. In another embodiment, as shown... Figure 7 As shown, the wrapping layer 13 may include multiple first wrapping layers 131, each first wrapping layer 131 being stacked sequentially, and at least one second wrapping layer 132 being stacked on the outside of the outermost first wrapping layer 131, and any two adjacent layers can be bonded and fixed together by an adhesive layer 134.

[0058] Optionally, when the first wrapping layer 131 and the second wrapping layer 132 are provided with multiple layers, the first wrapping layer 131 and the second wrapping layer 132 can be stacked alternately or multiple layers of the first wrapping layer 131 or the second wrapping layer 132 can be stacked continuously, which provides a relatively flexible arrangement. As an example, considering factors such as cost and manufacturing process, the total number of layers of the first wrapping layer 131 and the second wrapping layer 132 can be designed to be two or three layers.

[0059] In some embodiments, such as Figure 1As shown, functional component 12 includes a cooling element 121 and a filter element 122. The cooling element 121 is connected to the medium section 11, and the filter element 122 is connected to the cooling element 121. The first coating layer 131 covers at least both the cooling element 121 and the filter element 122 simultaneously. Specifically, the cooling element 121 is a component used to cool the aerosol to reduce its temperature to a temperature suitable for human absorption; the filter element 122 is used to filter out larger particles mixed in the aerosol to improve its taste.

[0060] Optionally, in some implementations, flavoring capsules can be added to the filter element 122, or flavorings or other substances can be added to the cooling element 121 to adjust the flavor of the aerosol and provide a richer taste experience. Furthermore, by wrapping the cooling element 121 and the filter element 122 with a first coating layer 131, the volatilization and loss of the aforementioned flavoring substances can be effectively reduced, thus extending the product's shelf life.

[0061] In some embodiments, such as Figure 1 As shown, the functional component 12 may also include a support member 123, which may be disposed between the medium section 11 and the cooling member 121, or integrally formed with the cooling member 121, to provide support at the middle position of the aerosol generating article 1 and improve the structural strength.

[0062] To facilitate the explanation of the beneficial effects of the embodiments of the present invention, an aerosol generating article 1 (hereinafter referred to as Product A) provided in the embodiments of the present invention is compared with a related aerosol generating article (hereinafter referred to as Product B). Product A is formed by wrapping with a regenerated cellulose membrane layer 13, while Product B is formed by wrapping with conventional forming paper without a regenerated cellulose membrane.

[0063] The total particulate matter and nicotine content in the aerosol components of products A and B were measured, and the results are shown in Table 1. As can be seen from the data in Table 1, the aerosol particulate matter content and nicotine content of product A are both increased to some extent compared to product B.

[0064] Table 1. Content of aerosol components in product A and product B

[0065]

[0066] Flavor-enhancing capsules were added to filter elements 122 of both products A and B. After the capsules were broken, the products were placed in an environment with a temperature of 40°C and a humidity of 70% for 12 hours. The penetration of fragrance and moisture in the functional sections of the two products was observed, and the results are as follows. Figure 8 As shown in the figure, product A has a relatively clean overall appearance and does not show obvious signs of moisture or seepage, while product B shows more obvious signs of moisture and seepage.

[0067] As can be seen from the above comparison, Product A has a higher content of effective aerosol components than Product B, meaning less loss. Furthermore, under the same environmental conditions, Product A is less prone to moisture absorption and leakage. Therefore, Product A (i.e., the aerosol-generating product 1 provided in this embodiment of the invention) has better impermeability.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
