Abstract

The present invention relates to an electronic cigarette cartridge in which a deflection part, a smoking base part, a hollow part and a filter part are sequentially arranged in a packaging member. The packaging member is a hollow paper tube. The deflection part is arranged at the distal end of the packaging member and is composed of an inner wall of the packaging member and a first partition part. The first partition part is bonded or glued to the inner wall of the packaging member, and separates the deflection part from the smoking base part. The present invention provides various structures of electronic cigarette cartridges. Among them, the first invention discloses a structure of an electronic cigarette cartridge that can be used in common with resistance type or electromagnetic insertion type concentrated heating vapes and resistance type or electromagnetic circumferential heating vapes. The inductor in the cartridge is closed at one end and open at the other end. The open end is arranged toward the distal end of the cartridge. When an insert type smoking tool heating is used, the heating piece or heating needle of the smoking tool can be smoothly inserted into the smoking base from the opening. At this time, the inductor body can better play the role of heat conduction as a heat sink.

Description

[Technical Field]

[0001] The present invention relates to the technical field of non-combustible heated electronic cigarettes, and more particularly to an electronic cigarette cartridge suitable for both insertable smoking devices and wrap-around electromagnetic induction heaters. [Background technology]

[0002] Initially developed by major foreign tobacco companies such as Philip Morris International, heated tobacco products involve inserting a specially designed cartridge into a heating device, which burns the tobacco at a low temperature to release nicotine and aerosol. The low-temperature combustion temperature is approximately 300°C, much lower than the combustion temperature of conventional cigarettes, which exceeds 800°C. The carcinogenic content of the aerosol from heated tobacco is 80% lower than that of conventional cigarettes, reducing smokers' intake of mutagens by 70% and reducing the incidence of bronchitis and pneumonia by 46% and 36%, respectively. This has significantly reduced the harm caused to the human body by tobacco products and ushered in a new trend in tobacco consumption.

[0003] Currently, there are two main methods for heating non-combustible cartridges: one is to insert them into a smoking device equipped with a heating pin or heating sheet and heat them electrically, and the other is to use an electromagnetic induction method to encase the cartridges and heat them.

[0004] When using electric heating, a heating pin or heating sheet of a smoking device must be inserted into the aerosol-generating material in the cartridge, whereby the heating pin or heating sheet heats the smoking device and generates aerosol for the user to inhale. In this heating method, when the heating pin or heating sheet is inserted into the cartridge, the thrust generated during insertion displaces the smoking device or other functional parts within the cartridge. To solve this problem, prior art often uses an isolating member at the rear end of the smoking device to counteract the thrust generated during insertion. After heating is complete, the heating pin or heating sheet must be pulled out of the cartridge. In this case, the aerosol-generating material in the cartridge adheres to the heating pin or heating sheet or follows the heating pin or heating sheet into the smoking device, making cleaning the smoking device very difficult. Long-term accumulation of aerosol-generating material in the smoking device can easily lead to damage to the smoking device, ultimately resulting in losses for consumers. Prior art solutions to the above problem include covering the end of the smoking device in the cartridge with a sealing sheet or sealing it with a plug that has a passage for the heating sheet or heating pin.

[0005] Electromagnetic induction heating requires the installation of an electromagnetic coil within the smoking device and a receptor that is in direct physical contact with the aerosol-forming substrate within the cartridge. The induction source generates an alternating electromagnetic field. When the cartridge is inserted into the smoking device, the alternating electromagnetic field induces heat in the receptor, generating eddy currents and / or hysteresis losses. This heat induces heat in the receptor, heating the aerosol-forming substrate and generating the aerosol that the user inhales. This heating method eliminates the problem of inserting and removing the inductor because it is built into the cartridge. Conventional receptors are metal sheets placed in the center of the aerosol generator or coils placed along the inner wall of the cartridge. In the case of metal sheet heating, heat radiates from the inductor and gradually moves from the center to the periphery of the product. During this process, heat is gradually lost. In this case, the aerosol-generating material in the center and the peripheral aerosol-generating material receive different amounts of heat, resulting in extremely uneven heating, with the center of the aerosol-generating material being overheated and the peripheral aerosol being underheated. In the case of coil heating, unlike metal sheath heating, heat is first applied to the aerosol generator in the outer periphery and then gradually transferred to the center, with heat gradually being lost during the transfer process. In this case, the amount of heat applied to the aerosol generator in the center and the aerosol generator in the periphery is not the same, which can lead to uneven heating, with insufficient heat applied to the center of the aerosol generator and excessive heat applied to the periphery.

[0006] Current electronic cigarette cartridges suitable for electric heating and those suitable for electromagnetic induction heating differ structurally depending on the structure of the smoking device. That is, current cartridges for electric heating smoking devices cannot be used with electromagnetic heating smoking devices, and cartridges for electromagnetic heating smoking devices cannot be used with electric heating smoking devices. Because electromagnetic induction heating eliminates the issues associated with inserting and removing the cartridge during electric heating, it is expected that electromagnetic induction heating will replace electric heating in the future. However, at present, most consumers use electric heating smoking devices, while only a minority use electromagnetic induction smoking devices. Therefore, there is an urgent need to provide electronic cigarette cartridges suitable for both smoking devices, so that consumers who only own one type of smoking device can use them normally. Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention is achieved by the following technical means: First invention: The present invention relates to an electronic cigarette cartridge in which a flow guide portion, an aerosol-forming substrate portion, a hollow portion, and a filter portion are sequentially arranged in a packaging member.

[0010] The packaging member is a hollow paper tube. Its role is to package the flow guide section, aerosol-forming substrate section, hollow section, and filter section. The packaging member is made of a paper material that does not deform or produce odors even when heated at temperatures between 100 and 300°C. The length of the packaging member is 25 to 60 mm, the diameter of the outer tube is 5.5 to 8 mm, and the thickness of the packaging member is 0.05 to 2 mm. The packaging member is prefabricated using a roll forming machine, and the outer tube wall is wrapped with tipping paper of the same length as the packaging member itself, which can serve aesthetic purposes and the printing of product information.

[0011] The flow guide portion is located at the distal end of the packaging member and is formed by the inner cylindrical wall of the packaging member and the first divided member. The flow guide portion's function is to create a certain space between the distal end of the cartridge and the smoking device when the cartridge is inserted into the smoking device, thereby functioning as a passageway for airflow. This prevents undesirable high resistance to draw caused by the close contact between the distal end of the cartridge and the inner surface of the smoking device, and also prevents grease components contained in the smoking device from precipitating inside the device when the aerosol-generating material is heated, which could lead to device contamination. Optionally, multiple ventilation holes can be drilled through the cylindrical wall of the packaging member of the flow guide portion to further reduce resistance to draw and provide multiple airflow passages, thereby eliminating the current situation where air is only supplied from the distal end of the smoking cartridge. The length of the flow guide portion of the cartridge can be designed to be 0.5 to 6 mm, preferably 1 to 4 mm, and more preferably 1 mm.

[0012] The first divided member is attached or glued to the inner tube wall of the packaging member, separating the flow guide portion from the aerosol-forming substrate portion. The first divided member not only serves to separate the flow guide portion from the aerosol-forming substrate portion, but also to encase or seal the aerosol-forming substrate, preventing it from falling off. It also has minute air holes that serve as an air intake path. When using an adhesive method to design the packaging, the connection between the first divided member and the inner tube wall of the packaging member is not sealed. Therefore, the requirement for an air intake path can be met by simply selecting a highly breathable forming paper without providing an air hole in the first divided member. When using an adhesive method, the connection between the first divided member and the inner tube wall of the packaging member portion is sealed. If there is no gap between the first divided member and the inner tube wall of the packaging member portion, a punching method is required to provide an air intake path. If there is a gap between the first divided member and the inner tube wall of the packaging member portion, whether or not an air hole is required in the first divided member can be determined based on the actual situation.

[0013] The thickness of the first divided member is 0.1 to 3 μm, preferably 0.8 to 2 μm, and most preferably 1.05 μm.

[0014] The aerosol-forming substrate section is loaded with an aerosol-forming substrate and an inductor.

[0015] The aerosol-forming substrate is a particle made from tobacco and / or non-tobacco. The tobacco particles are obtained by grinding and granulating flakes or filaments of roasted, air-dried, sun-dried, white-roasted, or other flavored tobacco after re-roasting. The non-tobacco particles are obtained by grinding and granulating roots, stems, leaves, flowers, fruits, or seeds of plants other than tobacco. The length of the aerosol-forming substrate is 10 to 20 mm, preferably 12 to 16 mm, and more preferably 15 mm.

[0016] The inductor is formed by folding a continuous sheet or columnar magnetic conductive material one or more times. The longitudinal cross section of the inductor has an incompletely closed geometric shape. The inductor has one end and two legs, with the closed end referred to as the end and the two open sides referred to as the legs. The inductor is disposed within the aerosol-forming substrate and is surrounded by the aerosol-forming substrate. Since the inductor has a geometric shape that is not enclosed within the aerosol-forming substrate, a preferred inductor with a longitudinal cross section shaped like a ">" can divide the internal space of the aerosol-forming substrate into four zones a, b, c, and d of similar volume (see Figure 12), and the four zones can be homogenized. When using an electromagnetic induction heating device, the role of the inductor is to sense the alternating magnetic field generated by the electromagnetic coil within the device after the cartridge is inserted into the device, generate heat, and uniformly heat the aerosol-forming substrate. When using an insertable electric heating device, the heating pin is inserted into the cartridge to begin heating. Because the inductor has a higher thermal conductivity than the aerosol-forming substrate, it can transfer heat more evenly to the aerosol-forming substrate after heating. Regardless of the heating method, the presence of the inductor allows heat to be transferred more evenly to the aerosol-forming substrate across the entire area of ​​the aerosol-forming substrate, ensuring more uniform heating and further improving heating efficiency.

[0017] The hollow section is surrounded by the second dividing member, the inner cylindrical wall of the packaging member, and the filter section. The main function of the hollow section is to cool the temperature. Flavor particles or cooling particles can also be added to the hollow section. The length of the hollow section in the cartridge is 5 to 15 mm, preferably 8 to 12 mm, and most preferably 10 mm. The flavor particles can be particles made from fragrances / flavors directly supported on a porous substrate, or other plant particles that naturally contain flavor components. They can also be made from other harmless materials that can absorb heat and undergo deformation. The hollow section can also be provided with a cooling element or a filtering element, if necessary. The cooling element can be selected from a hollow filter rod to create a Venturi effect, which more quickly reduces the aerosol temperature to the optimal inhalation temperature.

[0018] The second partition is attached or glued to the inner wall of the packaging member, separating the hollow portion from the aerosol-forming substrate portion. The second partition prevents the aerosol-forming substrate from entering the hollow portion and serves to seal or enclose the aerosol-forming substrate. Like the first partition, the second partition has tiny air holes to allow the aerosol to pass through. When using the adhesive method for packaging, the second partition and the inner wall of the packaging member are not sealed, so the second partition can be selected without air holes. To meet the requirement of providing an air intake path, only highly permeable forming paper can be selected. When the second partition and the inner wall of the packaging member are glued and sealed, a punch is required to form an air hole to allow the aerosol to pass through. When there is a gap between the first partition and the inner wall of the packaging member, the need for an air hole in the first partition can be determined based on the actual situation.

[0019] The thickness of the second divided member is 0.1 to 3 μm, preferably 0.8 to 2 μm, and most preferably 1.05 μm.

[0020] The first divided member and the second divided member are made of flexible sheet material. The flexible sheet material is any one of 3000 CU to 20000 CU highly transparent molding paper, punched paper, punched aluminum foil, punched aluminum foil paper, punched high temperature resistant plastic film, punched silicone sheet, punched gel sheet, and punched polylactic acid sheet. The longitudinal cross section of the first divided member and the second divided member is either "]" shaped or "[" shaped. The first divided member and the second divided member are provided along the axial direction of the cartridge in four forms: "][", "[]", "]]", and "[[". The "]]" form is preferred.

[0021] The filter portion is provided at the proximal end of the packaging member and is made of a material that can filter and cool the aerosol. The main role of the filter is to cool and filter the aerosol. The filter may be made of acetate fiber or PLA fiber.

[0022] The filter can be constructed from a single solid filter rod or a combination of a solid filter rod and a hollow filter rod. When the filter is constructed from a single solid filter rod, the length of the filter rod is 5 to 20 mm, preferably 6 to 12 mm, and most preferably 10 mm. When the filter is constructed from a combination of a solid filter rod and a hollow filter rod, the combined filter length is 10 to 20 mm, preferably 18 mm, with the solid filter rod being 10 mm long and the hollow filter rod being 8 mm long.

[0023] The hollow filter rod may also be provided with popping beads that serve to enhance the aroma.

[0024] Preferably, the inductor is formed by folding a continuous magnetic conductive material once along a predetermined folding line, the folding line being located halfway along the length of the magnetic conductive material, and the longitudinal cross section of the folded inductor being shaped like a ">" character.

[0025] Preferably, the inductor is made from a continuous magnetically conductive material that is bent once, and the inductor has a "U" shaped longitudinal cross section. In this configuration, the inductor may have protrusions bent outward on both legs of the inductor, which support the inductor against the inner cylindrical wall of the packaging member.

[0026] JPEG0007823935000001.jpg19170. Its diameter is 50% to 100% of the diameter of the inner cylinder of the packaging material. When using this configuration, it is also possible to provide protrusions formed by bending the two legs of the inductor outward, and these protrusions support the inductor on the wall of the inner cylinder of the packaging material.

[0027] Preferably, the inductor is made by folding a continuous magnetic conductive material twice, and the longitudinal cross section of the inductor is in the shape of a frame.

[0028] Preferably, the inductor is made of a continuous magnetic conductive material folded an odd number of times, said odd number being ≧3.

[0029] The ends have a sawtooth or wavy cross section and the legs have an "8" or "II" shaped cross section.

[0030] Regardless of the above-described structural aspects, the inductor may be provided with a support portion.

[0031] The support portions are formed by bending the ends of the two legs outward toward the opening of the inductor, and the outermost ends of the two support portions are supported by the inner cylindrical wall of the packaging material. Most preferably, the support portions are set at an obtuse angle relative to the legs. The same effect can be achieved by setting the support portions at a right angle or an acute angle. Furthermore, it is preferable that the support portions and the legs can be smoothly connected by an R angle of a circular arc.

[0032] The design of the support and protrusions is primarily intended to reduce the contact area between the inductor and the inner cylindrical wall of the packaging material, thereby preventing the paper packaging material from overheating when the support generates heat during the heat transfer process, causing the packaging material to burn and emit an odor. Furthermore, the inductor can be stably supported to prevent it from shifting position within the packaging material, and the area of ​​the inductor can be further increased, thereby increasing the heat dissipation area and improving heat transfer efficiency.

[0033] In the case of JPEG0007823935000002.jpg9170, the curved surface of the inductor abuts against the inner cylindrical wall of the packaging material and can serve as support. Furthermore, if a protrusion is further provided on an inductor of this structure, the protrusion can also serve as support, supporting the inductor on the inner cylindrical wall of the packaging material. In either case, the inductor can be used without a support, or the support can be extended so that the support, protrusion, and arcuate surface function as a single unit to serve as support.

[0034] If the inductor has a "U" shaped cross section and has protrusions bent outward on the two legs of the inductor, the inductor can be supported without a support, or the support can be extended so that the support and the protrusions or arc surfaces together serve as support.

[0035] Regardless of the inductor's structure, the height of the inductor is set equal to or less than the length of the aerosol-forming substrate so that the inductor is always positioned on the aerosol-forming substrate. Furthermore, to ensure that the inductor is stably supported on the aerosol-forming substrate, the maximum distance between the two legs of the inductor is set equal to or less than the inner diameter of the packaging material. In this specification, the maximum distance between the two legs includes the thickness of the sheet material used for the inductor itself and the diameter of the columnar material. Furthermore, if the maximum distance between the two legs of the inductor is smaller than the inner diameter of the packaging material, providing a support is more convenient during loading. This is because, in this case, the inductor can be simply pushed into the packaging material, and the inductor is supported by the support without the need for any additional support means. The inductor can be used without the support and performs the same function, but when loading the inductor into the packaging material, a positioning device must be used to position the inductor within the packaging material, and when loading the aerosol-forming substrate into the packaging material, the positioning device must be removed. If the maximum distance between the two legs of the inductor is equal to the diameter of the inner tube of the packaging material, the inductor is pressed into the packaging material, and parts or ends of the two legs naturally attach to the inner tube wall of the packaging material due to the inductor's elasticity, so there is no need to provide supports.In either of the above cases, whether or not to provide protrusions is optional, depending on needs.

[0036] Preferably, both the first and second divided members comprise an inner ring sealing portion and an outer ring fitting portion, and the inner ring sealing portion directly contacts the aerosol-forming substrate and functions to package the aerosol-forming substrate together with the packaging member. The outer ring fitting portion functions to provide a portion that contacts the inner tube wall of the packaging member when the packaging member is attached or bonded. The inner ring sealing portion and the outer ring fitting portion are different portions of an integrated flexible sheet material. The inner ring sealing portion is a central portion of the integrated flexible sheet material and is annular. The diameter of the inner ring sealing portion is the same as the diameter of the inner tube of the packaging member or is directly and as close as possible to the diameter of the inner tube of the packaging member. The outer ring fitting portion is a portion that is integrated with the flexible sheet material other than the inner ring sealing portion. Furthermore, the outer ring fitting portion is a portion that follows the peripheral edge other than the outer periphery of the inner ring sealing portion, is folded, and is attached or adhered to the inner tube wall of the packaging member, and is flat or wrinkled.

[0037] Furthermore, the outer ring fitting portion may be cut before being folded so as to be integrally attached to the outer periphery of the inner ring sealing portion to form an annular, continuous sawtooth, continuous wave, or continuous gear shape, or so as to be partially attached to the outer periphery of the inner ring sealing portion to form a plurality of discontinuous protrusions. Cutting can reduce the volume of the outer ring fitting portion as well as the consumption of flexible sheet material.

[0038] Furthermore, when the outer ring fitting portion is integrally attached to the outer periphery of the inner ring sealing portion and formed into a circular ring shape, the first or second divided member takes on a wrinkled shape after being pushed in by the pushing rod and is stuck or adhered to the inner tube wall of the packaging member.

[0039] Furthermore, when the outer ring fitting portion is integrally attached to the outer periphery of the inner ring sealing portion to form a continuous sawtooth, continuous wave, or continuous gear shape, the first or second separate material component may take on a wrinkled shape after being pushed in by the push-in lever and attached or bonded to the inner tube wall of the packaging component, or may take on a flat state depending on the area of ​​the portion cut off when cut.

[0040] Furthermore, when the outer ring fitting portion is partially attached to form multiple discontinuous protrusions on the outer periphery of the inner ring sealing portion, the first or second divided member takes on a cutout shape after being pushed in by the pushing rod and is attached or bonded to the inner tube wall of the packaging member.

[0041] Preferably, the outer ring fitting portion of the first separate member is attached or bonded to the inner tube wall of the packaging member to such an extent that the continuous shape formed after cutting fits flat against the inner tube wall of the packaging member without wrinkling, bulging, or leaving gaps.

[0042] Preferably, the surface of the pusher lever is optionally provided with a number of grooves extending axially along the surface of the pusher lever when the second divided member material is pushed into the packaging member by the pusher lever and adhered or glued in place. While excess portions on the outer ring fitting portion would have formed wrinkles during the process of pushing the entire second divided member into the packaging member, the presence of the grooves allows these excess portions to subsequently slip into the grooves under the action of the pushing force. As a result, notches are formed between the outer ring fitting portion and the inner wall of the packaging member under the action of the grooves. These notches may always be present, whether by adhesion or glueing. These notches can be used as fume flow passages to adjust suction resistance and increase air permeability, and can also avoid or reduce the number of punches required for the flexible sheet material forming the second divided member.

[0043] Preferably, the ends of the legs of the inductor face the first divided member. The ends face the second divided member. A cartridge with this structure can be used for both resistive and electromagnetic peripheral heated smoking devices, as well as resistive and electromagnetic peripheral heated smoking devices. When an insert-type heated smoking device is used, the opening between the legs of the inductor can be used to insert a heating pin or heating sheet into the aerosol-generating object. In this case, the inductor can be used as a heat transfer medium to distribute heat more evenly throughout the aerosol-generating object. When an electromagnetic peripheral heated smoking device is used, the inductor acts as a heat generator that supplies heat to the aerosol-generating object and also allows the heat generated by the inductor to be more evenly transferred to the aerosol-generating object, improving heating efficiency.

[0044] The inductor is mounted on the first divided member, and the end of the leg is mounted on the second divided member. A cartridge with this structure is only used in resistance or electromagnetic peripheral heating smoking devices. The inductor acts as a heating element to supply heat to the smoking device, while also allowing the heat it generates to be transferred more evenly to the smoking device, improving heating efficiency.

[0045] Preferably, the filter part is composed of a solid filter rod alone or a combination of a solid filter rod and a hollow filter rod, and the hollow filter rod and the solid filter rod may or may not be closely connected. The hollow filter rod has at least one aerosol passage. The total cross-sectional area of ​​the aerosol passage is 30% to 90% of the total cross-sectional area of ​​the packaging member.

[0046] Preferably, the filter section is a combination of a solid filter rod and a hollow filter rod. The hollow filter rod is provided on the side of the filter close to the hollow section. In this case, the presence of an aerosol passage in the hollow filter rod causes the aerosol in the filter section to pass through the aerosol passage, generating a Venturi effect and rapidly reducing its temperature. After the hollow filter rod cools, the aerosol then enters the solid filter rod, further reducing its temperature and filtering it before being inhaled by the user, so the user's mouth does not become hot when inhaling the smoke.

[0047] When the filter part is composed of only a solid filter rod, a cooling element can be further added to the hollow part to ensure the cooling effect of the aerosol, and a filtering element can be further added to the hollow part to ensure the filtering effect of the aerosol. The cooling element and the filtering element are mature solutions in the prior art and will not be repeated here.

[0048] The magnetic conductive material is a material capable of converting electromagnetic energy into heat. Specifically, it is a paramagnetic or ferromagnetic metal or metal alloy, preferably an iron-nickel alloy, a manganese-zinc ferrite material, a nickel-zinc ferrite material, a cobalt alloy, pure iron, or stainless steel. The cobalt alloy is preferably a cobalt-based high-temperature alloy, a rare-earth cobalt hard magnetic alloy, or a tungsten-cobalt alloy. The stainless steel is preferably a martensitic steel, a ferritic steel, an austenitic steel, or an austenitic-ferritic (duplex) stainless steel.

[0049] The sheet of magnetic conductive material has a width of 0.5-4 mm and a thickness of 0.01-0.2 mm, and the pillar of magnetic conductive material has a diameter of 0.05-2 mm.

[0050] Second invention: The present invention relates to an inductor for an electronic cigarette cartridge, which is manufactured by the following steps:

[0051] Select a continuous sheet-shaped or cylindrical magnetic conductive material and determine whether the width and thickness of the sheet-shaped magnetic conductive material or the diameter of the cylindrical magnetic conductive material meet the requirements. If the requirements are not met, the material can be processed to meet the requirements. Specifically, the width of the sheet-shaped magnetic conductive material is 0.5 to 4 mm, the thickness is 0.01 to 0.2 mm, and the diameter of the cylindrical magnetic conductive material is 0.05 to 2 mm.

[0052] When a sheet-shaped magnetic conductive material is used, the width of the magnetic conductive material may be smoothly tapered within a certain range so that the two long sides of the magnetic conductive material have a continuous sawtooth, continuous wave, or continuous gear shape.Also, a plurality of arc-shaped or rectangular grooves may be uniformly formed on the two long sides of the magnetic conductive material.

[0053] When using a columnar magnetic conductive material, continuous threads may be formed on the surface of the magnetic conductive material by cutting, or a plurality of circular or rectangular grooves may be formed in the magnetic conductive material.

[0054] The continuous magnetic conductive material is cut to a predetermined length, which is set according to the length of the aerosol-forming substrate of the cartridge to be used, and is typically 1.5 to 4 times the length of the aerosol-forming substrate.

[0055] The magnetic conductive material obtained after cutting is placed in a mold and folded at least once to produce an inductor of a predetermined shape. The longitudinal cross section of the inductor has an incompletely closed geometric shape with one end and two legs. The closed end of the inductor is called the end, and the two open side faces are called the legs.

[0056] In addition, the ends of the two legs of the manufactured inductor may be bent outward in the opening direction of the inductor to form a support portion, or the two legs may be bent outward in the opening direction of the inductor to form a protrusion portion, or both a support portion and a protrusion portion may be provided.

[0057] When the manufactured inductor is loaded into a packaging member, the inductor is loaded into the packaging member of the cartridge by a loading device, and the inductor is attached to the inner cylindrical wall of the packaging member at the widest point between the two legs, two supports, or two protrusions of the inductor, and the aerosol-forming substrate is loaded into the packaging member so as to surround the inductor. The loading device is preferably a push-in type loading device, and can be selected to push in from the distal end or the proximal end.

[0058] Other elements not mentioned in this invention are the same as those in the first invention, and will not be repeated here.

[0059] Third invention: The present invention relates to an electronic cigarette cartridge in which a flow guide portion, an aerosol-forming substrate portion, a hollow portion, and a filter portion are sequentially arranged in a packaging member.

[0060] The packaging member is a hollow paper tube. Its role is to package the flow guide section, aerosol-forming substrate section, hollow section, and filter section. The packaging member is made of a paper material that does not deform or produce odors even when heated at temperatures between 100 and 300°C. The length of the packaging member is 25 to 60 mm, the diameter of the outer tube is 5.5 to 8 mm, and the thickness of the packaging member is 0.05 to 2 mm. The packaging member is prefabricated using a roll forming machine, and the outer tube wall is wrapped with tipping paper of the same length as the packaging member itself, which can serve aesthetic purposes and the printing of product information.

[0061] The flow guide portion is located at the distal end of the packaging member and is formed by the inner cylindrical wall of the packaging member and the first divided member. The flow guide portion's function is to create a certain space between the distal end of the cartridge and the smoking device when the cartridge is inserted into the smoking device, thereby functioning as a passageway for airflow. This prevents undesirable high resistance to draw caused by the close contact between the distal end of the cartridge and the inner surface of the smoking device, and also prevents grease components contained in the smoking device from precipitating inside the device when the aerosol-generating material is heated, which could lead to device contamination. Optionally, multiple vent holes can be drilled through the cylindrical wall of the flow guide portion to further reduce resistance to draw and provide multiple airflow passages, thereby eliminating the current situation where air is only supplied from the distal end of the smoking cartridge. The length of the flow guide portion of the cartridge can be designed to be preferably 0.5 to 24 mm, more preferably 1 mm.

[0062] The first partition is attached or glued to the inner wall of the packaging member, separating the flow guide portion from the aerosol-forming substrate portion. The first partition not only separates the flow guide portion from the aerosol-forming substrate portion, but also encases or seals the aerosol-forming substrate, preventing it from falling off. It also has minute air holes that serve as an air intake path. When using a glued-on packaging design, the connection between the first partition and the inner wall of the packaging member is not sealed. Therefore, the requirement for an air intake path can be met by simply selecting a highly breathable molding paper without providing air holes in the first partition. When using a glued-on packaging design, the connection between the first partition and the inner wall of the packaging member is sealed. A punched-out process is required to provide the air intake path. The thickness of the first partition is 0.1 to 3 μm, preferably 0.8 to 2 μm, and most preferably 1.05 μm.

[0063] The aerosol-forming substrate is loaded with an aerosol-forming substrate. The aerosol-forming substrate is particles made from tobacco and / or non-tobacco. The tobacco particles are obtained by grinding and granulating flakes or filaments of roasted, air-dried, sun-dried, white-roasted, or other flavored tobacco after re-roasting. The non-tobacco particles are obtained by grinding and granulating roots, stems, leaves, flowers, fruits, or seeds of plants other than tobacco. The length of the aerosol-forming substrate is 10 to 20 mm, preferably 12 to 16 mm, and more preferably 13 mm.

[0064] The hollow portion is surrounded by the second partition, the inner cylindrical wall of the packaging member, and a filter. The main function of the hollow portion is to cool the temperature. Flavoring particles can also be added to the hollow portion. The length of the hollow portion within the cartridge is 5 to 15 mm, preferably 8 to 12 mm, and most preferably 10 mm. The flavoring particles can be particles made directly from flavors / fragrances or other particles carrying flavoring components. A cooling element or a filtering element can also be provided in the hollow portion, if necessary. The second partition is fitted or adhered to the inner cylindrical wall of the packaging member, separating the hollow portion from the aerosol-forming substrate portion. The second partition separates the aerosol-forming substrate portion from the hollow portion, preventing the aerosol-forming substrate portion from entering the hollow portion. This seals or seals the aerosol-forming substrate portion. Like the first partition, the second partition has minute air holes formed as aerosol passages. When designing the packaging, if the second partition and the inner wall of the packaging member are not sealed, the second partition can be selected without air holes, and only highly breathable molding paper can be used to meet the requirement of providing an air intake path. If the second partition and the inner wall of the packaging member are glued together, they are sealed together. In this case, a punching method must be used to ensure a passage for the aerosol. The thickness of the second partition is 0.1-3 μm, preferably 0.8-2 μm, and most preferably 1.05 μm.

[0065] The flexible sheet material is any one of 3000 CU to 20000 CU highly transparent molding paper, punched paper, punched aluminum foil, punched aluminum foil paper, punched high temperature resistant plastic film, punched silicone sheet, punched gel sheet, and punched polylactic acid sheet. The longitudinal cross sections of the first divided member and the second divided member are both in a "]" or "[" shape. The first divided member and the second divided member are arranged along the axial direction of the cartridge in four shapes: "][", "[]", "]]", and "[[". The "]]" shape is preferred.

[0066] The filter section is provided at the proximal end of the packaging member and is made of a material capable of filtering and cooling the aerosol. The primary function of the filter is to cool and filter the aerosol. The filter may be made of acetate fiber or PLA fiber. The length of the filter is 5 to 20 mm, preferably 8 to 12 mm, and most preferably 10 mm. The filter section is made of a material capable of filtering and cooling the aerosol and is provided at the proximal end of the packaging member. The filter section may consist of a solid filter rod alone or a combination of a solid filter rod and a hollow filter rod, and the hollow filter rod may or may not be closely connected to the solid filter rod. The hollow filter rod has at least one aerosol passage, and the total cross-sectional area of ​​the aerosol passage is 30% to 90% of the total cross-sectional area of ​​the packaging member.

[0067] The electronic cigarette cartridge of the above structure does not have an inductor, and is therefore only suitable for use with resistive or electromagnetic insertion smoking devices.

[0068] If necessary for electromagnetic peripheral heating of the smoking device, the aerosol-forming substrate portion of the cartridge structure may also include an inductor. The inductor is a closed geometric structure formed by folding a continuous sheet or column of magnetically conductive material. The inductor is disposed within and surrounded by the aerosol-forming substrate. The geometric structure may be an ellipse, rectangle, triangle, or other irregular closed-loop structure. Because the inductor has a closed geometric structure, it may be molded in one piece using a mold.

[0069] Due to the inductor, the cartridge can be used in electromagnetic peripheral heated smoking devices. Because the inductor is designed as a closed shape, when the cartridge is heated by resistance heating or electromagnetic insert center heating, the heating pin or heating sheet is not inserted into the cartridge. Therefore, these cartridges are only suitable for peripheral heated smoking devices, not insert type heated smoking devices.

[0070] The magnetic conductive material is a material capable of converting electromagnetic energy into heat. Specifically, it is a paramagnetic or ferromagnetic metal or metal alloy, preferably an iron-nickel alloy, a manganese-zinc ferrite material, a nickel-zinc ferrite material, a cobalt alloy, pure iron, or stainless steel. The cobalt alloy is preferably a cobalt-based high-temperature alloy, a rare-earth cobalt hard magnetic alloy, or a tungsten-cobalt alloy. The stainless steel is preferably a martensitic steel, a ferritic steel, an austenitic steel, or an austenitic-ferritic (duplex) stainless steel. The sheet of magnetic conductive material has a width of 0.5-4 mm and a thickness of 0.01-0.2 mm, and the column of magnetic conductive material has a diameter of 0.05-2 mm.

[0071] The first and second divided members are both composed of an inner ring sealing portion and an outer ring fitting part. The inner ring sealing portion and the outer ring fitting portion are different portions of an integrated flexible sheet material. The inner ring sealing portion is at the center of the integrated flexible sheet material and is annular. The diameter of the inner ring sealing portion is the same as the inner tube diameter of the packaging member. The outer ring fitting portion is the portion of the integrated flexible sheet material other than the inner ring sealing portion. The flexible sheet material is any one of 3000 CU to 20000 CU highly transparent molding paper, punched paper, punched aluminum foil, punched aluminum foil paper, punched high-temperature resistant plastic film, punched silicone sheet, punched gel sheet, and punched polylactic acid sheet.

[0072] In the present invention, the method of setting the inductor and the specific shape of the inductor are different from those of the first invention, but other unspecified parts are the same as those of the first invention, so they will not be repeated here.

[0073] The inductor of the present invention is manufactured by the following means: Select a continuous sheet-shaped or cylindrical magnetic conductive material and determine whether the width and thickness of the sheet-shaped magnetic conductive material or the diameter of the cylindrical magnetic conductive material meet the requirements. If the requirements are not met, the material can be processed to meet the requirements. Specifically, the width of the sheet-shaped magnetic conductive material is 0.5 to 4 mm, the thickness is 0.01 to 0.2 mm, and the diameter of the cylindrical magnetic conductive material is 0.05 to 2 mm.

[0074] When a sheet-shaped magnetic conductive material is used, the width of the magnetic conductive material may be smoothly tapered within a certain range so that the two long sides of the magnetic conductive material have a continuous sawtooth, continuous wave, or continuous gear shape.Also, a plurality of arc-shaped or rectangular grooves may be uniformly formed on the two long sides of the magnetic conductive material.

[0075] When using a columnar magnetic conductive material, continuous threads may be formed on the surface of the magnetic conductive material by cutting, or a plurality of circular or rectangular grooves may be formed in the magnetic conductive material.

[0076] The continuous magnetic conductive material is cut to a predetermined length, which is set according to the length of the aerosol-forming substrate of the cartridge to be used, and is typically 1.5 to 4 times the length of the aerosol-forming substrate.

[0077] The magnetic conductive material obtained after cutting is placed in a mold and folded into the desired shape of the inductor, and the ends of the magnetic conductive material of the fabricated inductor are tightly joined to form a closed geometric shape.

[0078] In use, the fabricated inductor is loaded into the packaging of the cartridge using a loading device, and the aerosol-forming substrate is loaded into the packaging so as to completely surround the inductor. The loading device is preferably a push-type. Loading can be performed from either the distal end or the proximal end. Care must be taken when using the push-type loading device to prevent deformation of the inductor during loading. [Effects of the Invention]

[0079] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention discloses various electronic cigarette cartridge structures. The first invention discloses an electronic cigarette smoke cartridge structure that is universally applicable to both resistive and electromagnetic insertion-type central heating smoking devices and resistive and electromagnetic peripheral heating smoking devices. The inductor in this cartridge has a closed end and an open end, with the open end facing the distal end of the cartridge. When using an insertion-type heated smoking device, the heating piece or heating pin of the smoking device can be smoothly inserted into the aerosol-forming substrate through the opening without obstruction. In this case, the inductor functions as a heat sink, improving heat transfer. When using a peripheral heating smoking device, the inductor functions as a heating element that induces electromagnetic energy to generate heat and heat the smoking device. This invention solves the technical issues that are common to both insertion-type and peripheral heating smoking devices with current cartridges, thereby avoiding the inconvenience of users having to constantly switch between smoking device products. 2. In the first aspect of the present invention, the inductor is designed to have a specific structural form. A preferred structure is a ">" shape, in which the inductor divides the aerosol-forming substrate into four closely spaced regions at the aerosol-forming substrate portion, allowing the aerosol-forming substrate in each region to more uniformly receive heat transferred from the inductor. As a result, the aerosol-forming substrate is heated more uniformly and carbonized more thoroughly. 3. The first invention also discloses a technical solution for placing the open end of the inductor toward the proximal end of the cartridge, which is suitable for resistive or electromagnetic peripheral heating smoking devices. 4. The first and third inventions of the present invention disclose a flow guide section. The flow guide section creates a certain space between the distal end of the cartridge and the smoking device when the cartridge is inserted into the smoking device, functioning as an air passageway. This prevents significant and undesirable resistance to draw due to close contact between the distal end face of the cartridge and the inner surface of the smoking device. It also prevents grease components contained in the smoking device from precipitating on the device and contaminating it when the smoking device is heated. Furthermore, the flow guide section's packaging material may have multiple vent holes drilled through the cylindrical wall, further reducing resistance to draw and providing multiple air passages, solving the problem of current cartridges only allowing inhalation through the distal end of the cartridge. 5. In this invention, the smoking device is packaged and enclosed by providing a first and second partition. The area of ​​the flexible sheet material of the first partition is larger than the area of ​​the end face of the cardboard tube of the packaging member. It is fixed into the cardboard tube by pushing it with a cylindrical pusher and then attached to the packaging member by pasting or gluing. Compared to the conventional method of directly attaching a sealing sheet to the distal end face of the cartridge, this method is faster, more convenient, and more reliable, avoids localized sealing defects on the end face of the packaging member, and also preserves space for the flow guide. The second partition is made of a flexible sheet material, which replaces the current partition made of plastic, silicone, polylactic acid, or acetate in the cartridge structure. This significantly reduces manufacturing costs and makes it easier to control draw resistance. More importantly, using paper for the partition meets environmental requirements. 6. In the first invention, when the second divided member is inserted, multiple grooves can be formed in the axial direction on the surface of the pushing rod. During the process of pushing the entire second divided member into the packaging member, wrinkles would have formed in the excess portion of the outer ring fitting portion. These excess portions then slip into the grooves under the action of the pushing force. As a result, notches are formed between the outer ring fitting portion and the inner tube wall of the packaging member under the action of the grooves. These notches can be present at all times, whether they are adhered or bonded. These notches can be used as aerosol passages to adjust suction resistance and increase breathability, and can also avoid or reduce the number of punches required for the flexible sheet material forming the second divided member. 7. The first invention discloses various inductor structures. The inductor has a support and a protrusion, which not only increases the stability of the support to prevent the inductor from shifting, but also increases the heat-generating area and improves the efficiency of heat conduction. 8. In this second invention, a method for processing and manufacturing the inductor of the present invention is also disclosed. This method is simple and easy to use, making it easy to carry out large-scale industrial production. 9. This third invention also discloses an electronic cigarette smoking device cartridge structure applicable only to sheet-type or pin-insertion heating smoking devices. This smoking device cartridge structure includes a flow guide and uses a flexible sheet material instead of the existing plastic or silicone dividing member, resulting in high manufacturing efficiency, extremely low manufacturing costs, and environmental protection requirements. Another electronic cigarette smoking device cartridge structure applicable only to electromagnetic peripheral heating of the smoking device is also disclosed. The inductor body of this structure has a closed geometric structure, further ensuring uniformity of heat transfer and further improving heat transfer efficiency. 10. In the present invention, the first and second divided members each comprise an inner ring sealing portion and an outer annular embedded portion. The inner ring sealing portion and the outer ring fitting portion are separate components of a single flexible sheet material. The manufacturing and processing process for divided members with this structure is simple and inexpensive, further reducing the processing costs of the cartridge.

[0081] The present invention will be described in detail below with reference to the accompanying drawings and examples, but the scope of the present invention is not limited to these examples.

[0082] Among these, Examples 1 to 18 are embodiments of the first aspect of the present invention.

[0083] Examples 19 to 21 are embodiments of the second invention.

[0084] Examples 22 to 24 are embodiments of the third invention. [Example]

[0085] As shown in Figure 5, this example is an electronic cigarette cartridge comprising a packaging member sequentially arranged with a flow guide portion, an aerosol-forming substrate portion, a hollow portion, and a filter portion. The packaging member is a hollow paper tube. The length of the packaging member is 25 mm, the outer diameter of the packaging member is 5.5 mm, and the thickness of the packaging member is 0.05 mm, so the inner diameter of the packaging member can be calculated to be 5.45 mm. Here, the length of the flow guide portion is 2 mm, the length of the aerosol-forming substrate portion is 10 mm, the length of the hollow portion is 5 mm, and the length of the filter portion is 8 mm.

[0086] The flow guide portion is retained at the distal end of the packaging member, and is surrounded by the inner cylindrical wall of the packaging member and the first divided member. The distal end of the flow guide is open. When the first divided member is inserted into the parcel, the flow guide portion is formed automatically. The first divided member is attached to the inner cylindrical wall of the packaging member and separates the flow guide portion from the aerosol-forming base portion.

[0087] The aerosol-forming substrate unit is loaded with an aerosol-forming substrate and an inductor. The aerosol-forming substrate is particles made from tobacco plants. The tobacco particles are obtained by grinding and granulating roasted tobacco. The particle size of the produced tobacco particles is 3 to 5 mm.

[0088] As shown in Figure 13A, the inductor is formed by folding a continuous sheet of magnetic conductive material once along a predetermined folding line. The sheet-like magnetic conductive material is in the form of an iron-nickel alloy sheet having a width of 0.5 mm and a thickness of 0.01 mm. The folding line is located halfway along the length of the magnetic conductive material, and the longitudinal cross section of the inductor formed after folding is shaped like a ">" character.

[0089] The inductor is bent to form a sharp corner, with one end closed to form the sharp corner and both ends open due to the legs. The inductor is placed within the aerosol-forming substrate and surrounded by the aerosol-forming substrate. The ends of the inductor are located adjacent to the second divided member, and the ends of the two legs are placed and supported by the inner cylindrical wall of the packaging member; the height of the inductor is 8 mm, and the maximum distance between the two legs of the inductor is 5.45 mm. The sheet-shaped magnetic conductive material is rigid, and the bent inductor has elasticity to restore its original shape, which stably supports the inductor against the inner cylindrical wall of the packaging member. As shown in Figure 12, the inductor equally divides the aerosol-forming substrate within the packaging member into four regions a, b, c, and d, with approximately the same amount of aerosol-forming substrate in each region.

[0090] The hollow portion is formed by the second divided member, the inner cylindrical wall of the packaging member, and the filter portion. The second divided member is attached to the inner cylindrical wall of the packaging member and separates the hollow portion from the aerosol-forming substrate portion. The hollow portion is a cavity provided in the packaging member. The hollow portion functions as a buffer and provides cooling. In particular, the high-temperature aerosol generated by the heated aerosol-forming substrate naturally cools as it passes through the long passage formed by the hollow portion.

[0091] Depending on the cooling needs, a cooling element or hollow filter rod can be added to the hollow portion to further aid cooling.Flavoring particles or cooling particles can also be loaded into the hollow portion or sprayed onto the inner wall of the packaging member.

[0092] The filter section is provided at the proximal end of the packaging member. The filter is a filter rod made of acetate fiber, and serves to filter and cool the smoke generated from the aerosol-forming substrate so that it is suitable for inhalation by the user. The filter is selected so that it is individually filtered by the solid filter rod, resulting in low resistance to drawing.

[0093] Both the first and second divided members include an inner ring sealing portion and an outer ring fitting portion. The inner ring sealing portion is in direct contact with the aerosol-forming substrate and, together with the packaging member, serves to package the aerosol-forming substrate. The outer ring fitting portion serves to provide a portion that contacts the inner tube wall of the packaging member when the packaging member is attached or bonded. The inner ring sealing portion and the outer ring fitting portion are different components of the integrated flexible sheet material. As shown in Figure 22b, the inner ring sealing portion is the central portion of the integrated flexible sheet material and has an annular shape. The diameter of the inner ring sealing portion is the same as or directly and as close as possible to the diameter of the inner tube of the packaging member. The outer ring fitting portion is a portion of the integrated flexible sheet material other than the inner ring sealing portion.

[0094] The flexible sheet material is selected from highly transparent molding paper of 3000 CU to 20000 CU. The longitudinal cross sections of the first divided member and the second divided member are both in the shape of a "]". The cross sections of the first divided member and the second divided member in the packaging member after being pushed into the packaging member by the pushing rod are shown in Figure 23c.

[0095] During manufacturing, a paper material that does not deform or emit an odor even when heated at 100 to 300°C is rolled into a packaging member using a roll forming machine. Next, a pre-cut and formed second divided member is pushed from the distal end of the packaging member through a pushing rod to a designated position within the packaging member. Next, a bent and formed inductor is pushed from the distal end of the packaging member through a pushing device to a designated position within the packaging member. The prepared aerosol-forming substrate is loaded into the packaging member from the distal end of the packaging member using a loading device. After loading of the aerosol-forming substrate is completed, the second divided member is pushed from the distal end of the packaging member through a push stem to a designated position within the packaging member. Finally, after the hollow portion is reserved within the packaging member, a filter rod is loaded into the packaging member from the proximal end of the packaging member using a loading device.

[0096] Tipping paper or other stickers may be applied to the outer wall of the packaging member according to aesthetic and other commercial requirements.

[0097] For a smoother connection, the end of the inductor in this embodiment is also treated with a smooth connection. A longitudinal cross-sectional view of the inductor in the cartridge of this embodiment is shown in Figure 13a. This cartridge can be used in both electromagnetic induction smoking devices and insertable electric smoking devices. When using an electromagnetic induction heating device, the inductor's role is to sense the alternating magnetic field generated by the electromagnetic coil inside the device after the cartridge is inserted into the device, generate heat, and uniformly heat the aerosol-forming substrate. Configuring the inductor in a ">" shape facilitates heat transfer. When using an insertable electric heating device, the heating pin is inserted into the cartridge to begin heating. Because the inductor has a higher thermal conductivity than the aerosol-forming substrate, it can more uniformly transfer heat to the aerosol-forming substrate after heating. Arranging the inductor in a ">" shape facilitates insertion of the heating pin and eliminates resistance from the inductor when the heating pin is inserted into the cartridge. Regardless of the heating method, the presence of the inductor allows for uniform heat transfer to aerosol-forming substrates a, b, c, and d in the aerosol-forming substrate section, ensuring more uniform heating and further improving heating efficiency.

[0098] In a more preferred embodiment, the support portions are formed by bending the ends of the legs of the inductor (see FIG. 13b). An inductor with a support portion can be supported on the inner cylindrical wall of the packaging member via the support portion. [Example]

[0099] The length of the packaging member is 60 mm, the diameter of the outer tube is 8 mm, and the thickness of the packaging member is 2 mm, so the diameter of the inner tube of the packaging member can be calculated as 6 mm. Here, the length of the flow guide portion is 5 mm, the length of the aerosol-forming substrate portion is 20 mm, the length of the hollow portion is 15 mm, and the length of the filter portion is 20 mm.

[0100] The aerosol-forming substrate unit is loaded with an aerosol-forming substrate and an inductor. The aerosol-forming substrate is particles made from non-tobacco plants. The non-tobacco plant particles are obtained by crushing and granulating tea leaves. The tobacco particles produced are 2 to 3 mm in size.

[0101] The magnetic conductive material is a cylindrical manganese zinc ferrite material with a diameter of 0.05 mm. A longitudinal cross section of the inductor in the cartridge is shown in Figure 14a. The inductor is made of a continuous cylindrical magnetic conductive material after being bent once. The longitudinal cross section of the inductor is "U" shaped, the height of the inductor is 18 mm, and the maximum distance between the two legs of the inductor is 3 mm.

[0102] The filter is located at the base end of the packaging member. The filter section combines a solid filter rod and a hollow filter rod made of acetate fiber. The solid filter rod is 11 mm long, and the hollow filter rod is 9 mm long. The total cross-sectional area of ​​the aerosol channels in the hollow filter rod is 30% of the total cross-sectional area of ​​the packaging member. The hollow filter rod is located closer to the hollow portion of the filter. In this case, because an aerosol passage exists within the hollow filter rod, a Venturi effect occurs as the aerosol passes through the aerosol passage in the filter, causing a rapid drop in temperature. The filter rod is inserted into the solid filter rod for further processing, cooling, and filtering before being delivered to the user. As a result, the aerosol inhaled by the user is no longer hot.

[0103] The vertical cross section of the first divided member is shaped like "[". The vertical cross sections of the second divided members are both shaped like "]". The first divided member and the second divided member are made of punched aluminum foil.

[0104] As shown in Fig. 22a, the outer ring fitting portions of the first and second divided members are annular. Fig. 23c shows a cross section of the first and second divided members inside the packaging member after they have been pushed into the packaging member by the pushing rod. The rest is the same as in Example 1.

[0105] Because the inductor of this embodiment has no support or protrusions and the distance between the two legs of the inductor is 3 mm, a pusher rod with a positioning function must be used to load the inductor of this embodiment. Once the inductor is pressed into the appropriate position in the packaging material, loading of the aerosol-forming substrate begins. While loading, the pusher lever is pulled out to align the central axis of the inductor with the central axis of the packaging material. Even if the central axis of the inductor and the central axis of the packaging material are not perfectly aligned, this error is acceptable as long as it does not affect the insertion of the heating pin or additional pieces. [Example]

[0106] The two legs of the inductor are provided with protrusions formed by bending them outward. The protrusions are supported by the inner cylindrical wall of the packaging material, and the maximum distance between the two legs of the inductor is the distance between the apexes of the two protrusions, which is 6 mm. The ends of the legs are bent outward to form support portions. The distance between the outermost ends of the support portions is also 6 mm. A longitudinal cross-sectional view of the inductor of the cartridge of this embodiment is shown in Figure 14d.

[0107] The inductor in this embodiment may have only a support portion without a protrusion portion, if necessary. The structure formed by folding the support portion is shown in Figure 14b. The structure formed by bending the support portion is shown in Figure 14c. The rest is the same as in Example 2. [Example]

[0108] The length of the packaging member is 45 mm, the diameter of the outer tube of the packaging member is 7.1 mm, and the thickness of the packaging member is 0.1 mm, so the diameter of the inner tube of the packaging member can be calculated to be 7 mm. Here, the length of the flow guide portion is 0.5 mm, the length of the aerosol-forming substrate portion is 10 mm, the length of the hollow portion is 14.5 mm, and the length of the filter portion is 20 mm.

[0109] The aerosol-forming substrate unit is loaded with an aerosol-forming substrate and an inductor. The aerosol-forming substrate is particles made from a non-tobacco plant. The non-tobacco plant particles are obtained by crushing and granulating cassava.

[0110] The inductor is made from a single bend of continuous magnetic conductive material, which is nickel-zinc ferrite material with a width of 4 mm and a thickness of 0.2 mm. JPEG0007823935000003.jpg11170 Because the longitudinal cross section of the inductor is an arc larger than a semicircle, the maximum distance between the two legs of the inductor is the diameter of the arc. The diameter of the arc is 90% of the inner diameter of the packaging member, or 6.3 mm. The height of the inductor is 6 mm. A longitudinal cross section of the inductor of the cartridge of this embodiment is shown in Figure 15a.

[0111] In this embodiment, the maximum distance between the two legs of the inductor is 6.3 mm, and the diameter of the inner tube of the packaging material is 7 mm. Therefore, when loading, a pusher rod with a positioning function must be used, and loading must be performed according to the loading method of Example 2 while pulling out the pusher rod.

[0112] In this embodiment, both the first and second divided members are made of punched paper. As shown in Figure 1, the longitudinal cross section of the first divided member in this embodiment is shaped like a square bracket, and the longitudinal cross section of the second divided member is shaped like a square bracket. As shown in Figure 22c, the outer ring fitting portions of the first and second divided members are cut into multiple continuous arcs, forming a flower-like shape. Figure 23b shows the wrinkles formed when divided members with this structure (i.e., including the first and second divided members) are pressed into the packaging member because the outer ring fitting portions are not on the inner tube wall of the packaging member. This structure reduces wrinkles and suction resistance. The rest of the structure is the same as in Example 1. [Example]

[0113] The two legs of the inductor are provided with support portions bent outward. The support portions are supported by the inner cylindrical wall of the packaging material. In this case, the maximum distance between the two legs of the inductor is the distance between the end points of the two support portions, which is 7 mm. A longitudinal cross-sectional view of the inductor of the cartridge of this embodiment is shown in Figure 15b.

[0114] As shown in Figure 15c, the inductor of this example can be provided with additional protrusions as needed. The distance between the two end points of the protrusions is preferably the same as the diameter of the inner cylinder of the packaging material, which is 7 mm. The rest is the same as in Example 4. [Example]

[0115] The length of the packaging member is 55 mm, the diameter of the outer tube of the packaging member is 7.5 mm, and the thickness of the packaging member is 1.2 mm, so the diameter of the inner tube of the packaging member can be calculated as 6.3 mm. Here, the length of the flow guide portion is 5 mm, the length of the aerosol-forming substrate portion is 15 mm, the length of the hollow portion is 15 mm, and the length of the filter portion is 20 mm.

[0116] The inductor is made by folding a continuous cylindrical magnetic conductive material twice.

[0117] The longitudinal cross section of the inductor is frame-shaped, and the height of the inductor is 14 mm. The maximum distance between the two legs of the inductor is 3.15 mm. Figure 16a shows a longitudinal cross section of the inductor in the cartridge of this embodiment. The cartridge uses a "frame-shaped" inductor as shown in Figure 16a. During installation, the pushing rod must be pulled out while loading the aerosol-forming substrate. To better support the inductor, support portions may be formed by bending them at both ends of the inductor's legs. As shown in Figure 16b, the distance between the outermost ends of the two support portions is 6.3 mm.

[0118] In this embodiment, the first divided member is made of punched aluminum foil paper, and the second divided member is made of punched paper.

[0119] Of these, the first separate member is cut from punched aluminum foil into a shape with multiple acute angles, as shown in Figure 22d, with the acute angles forming the outer ring fitting portion. The acute angles are not cut all the way to the inner ring sealing portion, while the second separate member is cut into a shape with multiple sharp angles, as shown in Figure 22g. The acute angles form the outer ring fitting portion, and these acute angles are sheared all the way to the inner ring sealing portion, with no continuity between any two adjacent acute angles.

[0120] In this embodiment, the first divided member is adhesively disposed within the packaging member. The second divided member is adhesively disposed within the packaging member. The cross section of the first divided member after being pushed into the packaging member through the pushing rod is shown in Figure 23d. The cross section of the second divided member after being pushed into the packaging member through the pushing rod is shown in Figure 23a. The rest is the same as in Example 1. [Example]

[0121] The length of the packaging member is 50 mm, the diameter of the outer tube of the packaging member is 6.6 mm, and the thickness of the packaging member is 0.1 mm, so the diameter of the inner tube of the packaging member can be calculated to be 6.4 mm. Here, the length of the flow guide portion is 5 mm, the length of the aerosol-forming substrate portion is 15 mm, the length of the hollow portion is 12 mm, and the length of the filter portion is 18 mm.

[0122] The inductor is made of a continuous magnetic conductive material after being bent an odd number of times, where the odd number is 3. As shown in Figure 18a, the longitudinal section of the end is sawtooth-shaped, the longitudinal section of the leg is "II"-shaped, the height of the inductor is 14 mm, and the maximum distance between the two legs of the inductor is 3.2 mm.

[0123] In the case of a cartridge employing the inductor shown in FIG. 18a, the aerosol-forming substrate needs to be loaded while the pusher rod is being withdrawn during installation, and therefore a positionable pusher rod needs to be used.

[0124] In this example, both the first and second divided members are made of punched silicone sheets. As shown in Photo 2, the longitudinal cross section of the first divided member in this example is "[" shaped. The longitudinal cross sections of both second divided members are also "[" shaped. As shown in Figure 22e, the outer ring fitting portions of the first and second divided members are cut into multiple continuous trapezoids, with adjacent trapezoids not connected, forming a gear-like shape. After the first and second divided members are pushed into the packaging member by the pushing rod, the cross section of the packaging member has a smooth, flat structure, as shown in Figure 23a.

[0125] The filter unit is located at the base end of the packaging member. The filter unit is a combination of a solid filter rod and a hollow filter rod made of acetate fiber, with the solid filter rod being 10 mm long and the hollow filter rod being 8 mm long. The total cross-sectional area of ​​the aerosol channels in the hollow filter rod is 50% of the total cross-sectional area of ​​the packaging member. The hollow filter rod is located closer to the hollow portion of the filter. Because the aerosol channel is present in the hollow filter rod, the aerosol passes through the aerosol passage of the filter unit, causing a Venturi effect, resulting in a rapid drop in temperature. The aerosol cooled by the hollow filter rod enters the solid filter rod, where it is further cooled and filtered before being supplied to the filter unit. This prevents the aerosol from becoming hot after entering the user's mouth. Other features are the same as in Example 1. [Example]

[0126] The longitudinal cross section of the leg is "eight" shaped, and the maximum distance between the two legs of the inductor is 6.4 mm. A longitudinal cross section of the inductor of the cartridge of this example is shown in Figure 17a. The rest is the same as in Example 7. [Example]

[0127] The inductor is made of a continuous magnetic conductive material after being bent an odd number of times. The odd number is 5, and the longitudinal cross-sectional structure of the formed inductor is shown in Figure 17b. In this embodiment, if the maximum distance between the two legs of the inductor is less than 6.4 mm, a support portion may be provided as needed. The support portion is formed by bending the ends of the two legs outward toward the opening of the inductor. The outermost ends of the two support portions are supported by the inner cylindrical wall of the packaging material. The specific structure is shown in Figure 17c. The rest is the same as in Example 8. [Example]

[0128] The inductor is made of a continuous magnetic conductive material after being bent an odd number of times, where the odd number is 5. The longitudinal cross-sectional structure of the formed inductor is shown in Figure 18b. If the maximum distance between the two legs of the inductor in this embodiment is less than 6.4 mm, a support may be provided as needed.

[0129] The support parts are formed by bending the ends of the two legs outward toward the opening of the inductor. The outermost ends of the two support parts are supported by the inner cylindrical wall of the packaging material. The specific structure is shown in Figure 18c. The rest is the same as in Example 7. [Example]

[0130] The length of the packaging member is 41 mm, the diameter of the outer tube of the packaging member is 6.6 mm, and the thickness of the packaging member is 0.1, so the diameter of the inner tube of the packaging member can be calculated to be 6.4 mm. Here, the length of the flow guide portion is 1 mm, the length of the aerosol-forming substrate portion is 15 mm, the length of the hollow portion is 10 mm, and the length of the filter portion is 15 mm.

[0131] The inductor is made of a continuous magnetic conductive material after being bent an odd number of times.

[0132] The odd number is 3. The longitudinal cross section of the tip is wavy, and the longitudinal cross section of the legs is "II" shaped. The height of the inductor is 12 mm, and the maximum distance between the two legs of the inductor is 3.2 mm. A longitudinal cross section of the inductor of the cartridge of this embodiment is shown in Figure 20a.

[0133] In this embodiment, both the first and second divided members are made of punched gel sheets. As shown in Figure 2, the longitudinal cross-sectional shapes of the first and second divided members in this embodiment are both "[" shaped. As shown in Figure 22f, the outer ring fitting portions of the first and second divided members are cut into multiple continuous trapezoids, with two adjacent trapezoids tightly joined to form a gear-shaped outer ring, and the portion near the inner ring fitting portion has a shape similar to a ring. Figure 23d shows the cross-sections of the first and second divided members inside the packaging member after being pushed into the packaging member by the pushing rod. Wrinkles occur in the outer ring fitting portions when squeezed. The rest is the same as in Example 1. [Example]

[0134] The longitudinal cross section of the legs is "eight" shaped, and the maximum distance between the two legs of the inductor is 6.4 mm. A longitudinal cross section of the inductor of the cartridge of this example is shown in Figure 19a. The rest is the same as in Example 11. [Example]

[0135] The inductor is made of a continuous magnetic conductive material after being bent an odd number of times. The odd number is 5. An inductor with this structure is shown in Figure 20b. If the maximum distance between the two legs of the inductor in this embodiment is less than 6.4 mm, a support portion can be provided as needed. The support portion is formed by bending the ends of the two legs outward toward the opening of the inductor. The outermost ends of the two support portions are supported by the inner cylindrical wall of the packaging material. The specific structure is shown in Figure 20c. The rest is the same as in Example 11. [Example]

[0136] The inductor is made by folding a continuous magnetic conductive material five times. The structure of the manufactured inductor is shown in Figure 19b. In this embodiment, if the maximum distance between the two legs of the inductor is less than 6.4 mm, a support portion can be provided as needed. The support portion is formed by folding the ends of the two legs outward toward the opening of the inductor. The outermost ends of the two support portions are supported by the inner cylindrical wall of the packaging material. The specific structure is shown in Figure 19c. The rest is the same as in Example 12. [Example]

[0137] The length of the packaging member is 60 mm, the diameter of the outer tube of the packaging member is 8 mm, and the thickness of the packaging member is 0.05 mm, so the diameter of the inner tube of the packaging member can be calculated to be 7.95 mm. Here, the length of the flow guide portion is 5 mm, the length of the aerosol-forming substrate portion is 20 mm, the length of the hollow portion is 15 mm, and the length of the filter portion is 20 mm.

[0138] The inductor is made by folding a continuous sheet of magnetically conductive material four times. The magnetically conductive material is a cobalt-based high-temperature alloy with a width of 3.6 mm and a thickness of 0.096 mm. A longitudinal cross section of the inductor is shown in Figure 21a. The formed end of the inductor has a smooth structure. The legs are shaped like a "><", the inductor is 18 mm high, and the minimum distance between the two legs of the inductor is 2 mm. The maximum distance between the two legs of the inductor is 7.95 mm. The ends of the inductor in this embodiment can be bent into an arc if necessary, thereby forming the structure shown in Figure 21b. The rest is the same as in Example 1. [Example]

[0139] The second divided member described in Examples 1 to 16 is pushed into the packaging member by the pushing rod and attached or glued in place, thereby forming slight grooves in the axial direction on the surface of the pushing rod. The grooves in the pushing rod have a certain angle, and the depth of the grooves in the axial direction of the pushing rod is gradual. The grooves at the tip of the pushing rod are deepest, and the grooves in the center of the pushing rod are shallowest.

[0140] If the entire second divided member were to be pushed into the packaging member, wrinkles would form in the excess portion of the outer ring fitting portion. However, due to the presence of the groove, the extrusion force causes these excess portions to enter the groove, positioning the outer ring fitting portion between the outer ring fitting portion and the inner tube wall of the packaging member. As shown in Figure 23e, a notch is formed. Whether adhesive or glue is used, a notch is always present. Forming a notch notch notches not only provides an aerosol passage, adjusting suction resistance and improving breathability, but also avoids or reduces the number of punches required in the flexible sheet material that makes up the second divided member. [Example]

[0141] The inductor mounting orientation for the cartridges described in Examples 1 to 16 is shown in Figures 1, 2, 5, and 10. The end of the inductor's legs is positioned on the first divided member side, and the end of the inductor's legs is positioned on the second divided member side. See Figures 24, 25, 28, and 30. Cartridges of this structure are commonly used in resistive or electromagnetic insertion-type central heating smoking devices and resistive or electromagnetic peripheral heating smoking devices. When using an insertion-type smoking device, the opening between the two legs of the inductor allows a heating pin or heating sheet to be inserted into the smoking device. In this case, the inductor functions as a heat transfer medium, distributing heat more evenly to all corners of the aerosol-generating device. When using a peripheral heating smoking device, the inductor functions as a heating element that provides heat to the aerosol-generating device, while also transferring heat generated by the inductor itself more evenly to the aerosol-generating device, improving heating efficiency. [Example]

[0142] The inductor described in Examples 1 to 16 is attached to the cartridge in the following direction: As shown in Figures 6 and 7, the end of the inductor is located on the first divided member side, and the end of the leg of the inductor is located on the second divided member side. As shown in Figures 29 and 31, a cartridge with this structure is used only in a resistance-type or electromagnetic peripheral-type heated smoking device, and the inductor functions as a heating element that provides heat to the aerosol generator, transferring the heat it generates more evenly to the aerosol generator and improving the heating effect of the aerosol generator. [Example]

[0143] The inductor is made by the following steps and is used in an electronic cigarette cartridge. (1) A continuous iron-nickel alloy is selected as a magnetic conductive material, and processed into a sheet material 4 mm wide and 0.2 mm thick. (2) The continuous magnetic conductive material is cut to a length 2.5 times the length of the aerosol-forming substrate portion. (3) The cut magnetic conductive material is placed in a mold and folded once to create an inductor of the desired shape. The longitudinal cross section of the inductor has an incompletely closed geometric shape, with one end and two legs. The closed end of the inductor is called the end, and the two open sides are called the legs. The prepared inductor is shown in Figure 13a. (4) As shown in FIG. 13b, the ends of the two legs of the fabricated inductor are bent outward toward the opening of the inductor to form support portions.

[0144] When loading the manufactured inductor into a packaging member, the aerosol-forming substrate is loaded so as to surround the inductor so that the widest part between the two legs or two supports of the inductor is attached to the inner cylindrical wall of the packaging member.

[0145] The loading device is preferably a push-in type loading device, and can be selected to be pushed in from the distal end or the proximal end. [Example]

[0146] Continuous austenitic steel is selected as the magnetic conductive material. The material is processed into a sheet with a width of 2 mm and a thickness of 0.05 mm, and the continuous magnetic conductive material is cut to a length three times the length of the aerosol-forming substrate. The cut magnetic conductive material is placed in a mold, and an inductor of the desired shape is produced in a single bending process. The longitudinal cross section of the inductor has an incompletely closed geometric shape. The inductor has one end and two legs, with the closed end of the inductor called the end and the two open sides called the legs. The prepared inductor is shown in Figure 14a.

[0147] As shown in Figure 14b, the ends of the two legs of the fabricated inductor can be bent outward towards the opening of the inductor to also form supports.

[0148] It is also possible to process the angle between the two legs of the inductor and the support into a circular arc with an R angle. The effect after processing is shown in Figure 14c.

[0149] With or without supports, the two legs of the fabricated inductor can be bent outward to create protrusions. The structure of the inductor including the protrusions is shown in Figure 14d.

[0150] When the manufactured inductor is loaded into a packaging member, the inductor is loaded into the packaging member of the cartridge by a loading device, and the inductor is attached to the inner cylindrical wall of the packaging member at the widest point between the two legs, two supports, or two protrusions of the inductor, and the aerosol-forming substrate is loaded into the packaging member so as to surround the inductor. The loading device is preferably a push-in type loading device, and can be selected to push in from the distal end or the proximal end. [Example]

[0151] A continuous tungsten-cobalt alloy was selected as the magnetically conductive material and processed into a cylindrical material with a diameter of 0.15 mm. The continuous magnetically conductive material was cut to a length four times the length of the aerosol-forming substrate. The cut magnetically conductive material was placed in a mold and folded five times to create an inductor of the desired shape. The longitudinal cross section of the inductor had an incompletely closed geometric shape. The inductor had one end and two legs, with the closed end referred to as the end and the two open sides referred to as the legs. The prepared inductor is shown in Figure 17b.

[0152] The ends of the two legs of the fabricated inductor can be bent outward toward the opening of the inductor to form a support. The angle between the two legs of the inductor and the support can also be rounded with an R angle. The effect after processing is shown in Figure 17c.

[0153] When the manufactured inductor is loaded into the packaging member, the inductor is attached to the inner cylindrical wall of the packaging member at the widest point between the two legs and the two supports, and the aerosol-forming substrate is loaded into the packaging member so as to surround the inductor. The loading device is preferably a push-in type loading device, and can be selected to push in from the distal end or the proximal end. [Example]

[0154] The electronic cigarette cartridge is configured by arranging a flow guide portion, an aerosol-forming substrate portion, a hollow portion, and a filter portion in this order within a packaging member.

[0155] The packaging material is a hollow paper tube. The length of the packaging material is 50 mm, the diameter of the outer tube of the packaging material is 8 mm, and the thickness of the packaging material is 0.5 mm, so the diameter of the inner tube of the packaging material can be calculated to be 7.5 mm.

[0156] The packaging member is prefabricated by a roll forming machine, and the outer wall of the packaging member is wrapped with tipping paper of the same length as the packaging member itself, which can serve aesthetic purposes and product information printing purposes.

[0157] The flow guide portion is disposed at the distal end of the packaging member. The flow guide portion is formed by the inner cylindrical wall of the packaging member and the first divided member. When the cartridge is inserted into the smoking device, the flow guide portion creates a space between the distal end of the cartridge and the smoking device, functioning as an air flow path, and thus prevents clogging between the distal end of the cartridge and the smoking device, resulting in significant and unfavorable resistance to draw. Optionally, the cylindrical wall of the packaging member enclosing the flow guide portion may also be provided with multiple air vents penetrating the cylindrical wall to further reduce resistance to draw. Furthermore, providing multiple air passages changes the current situation where current cartridges draw air from their distal end. The length of the flow guide portion on the cartridge is 2 mm.

[0158] The first divided member is adhered to the inner wall of the packaging member and separates the flow guide portion from the aerosol-forming substrate portion. The first divided member not only separates the flow guide portion from the aerosol-forming substrate portion, but also encases or seals the aerosol-forming substrate to prevent it from falling off. There is a small air hole to provide an intake passage. The thickness of the first divided member is 1.05 μm.

[0159] The aerosol-forming substrate is loaded with an aerosol-forming substrate. The aerosol-forming substrate is tobacco particles. The tobacco particles are obtained by re-roasting flakes or filaments of roasted, air-dried, sun-dried, white-roasted, or other flavored tobacco, followed by grinding and granulation. The aerosol-forming substrate has a length of 15 mm.

[0160] The hollow space is surrounded by the second dividing member, the inner wall of the packaging member, and the filter. The main function of the hollow space is to cool the temperature. Flavor particles can also be added to the hollow space. The length of the hollow space in the cartridge is 13 mm. The flavor particles can be particles made directly from flavors / fragrances or other particles carrying aromatic components.

[0161] The second partition is attached to the inner wall of the packaging member and separates the hollow portion from the aerosol-forming substrate. The second partition separates the aerosol-forming substrate from the hollow portion and prevents the aerosol-forming substrate from entering the hollow portion. This seals or seals the aerosol-forming substrate. When designing the packaging, since there is no sealing connection between the second partition and the inner wall of the packaging member, no air holes are provided in the second partition; only highly permeable molding paper is used to provide an air inlet. The thickness of the second partition is 1.05 μm.

[0162] The first divided member is made of punched paper, and the second divided member is made of 2000 CU highly transparent molded paper, and the longitudinal cross sections of the first divided member and the second divided member are both in the shape of "]".

[0163] The filter element is made of a material capable of filtering and cooling aerosols and is disposed at the proximal end of the packaging member. The filter element is composed of a solid filter rod and a hollow filter rod. The solid filter rod is 11 mm long and the hollow filter rod is 9 mm long, and the hollow filter rod and the solid filter rod may or may not be closely connected. The hollow filter rod is provided with at least one aerosol passage, and the total cross-sectional area of ​​the aerosol passage is 30% of the total cross-sectional area of ​​the packaging member.

[0164] Since there is no inductor, this smoking device cartridge is only applicable to resistive or electromagnetic insertion type central heating smoking devices. For specific usage, please refer to Figures 26 and 27. [Example]

[0165] The aerosol-forming substrate is also loaded with an inductor. The inductor is made of a continuous sheet or cylindrical magnetic conductive material folded to form a closed geometric structure. The inductor is disposed within and surrounded by the aerosol-forming substrate. The rest is the same as in Example 23.

[0166] The geometric structure may be an ellipse, a rectangle, a triangle, or other irregular closed-loop structure. Because the inductor has a closed geometric structure, the inductor can also be pre-formed in one pass through a mold. Because the inductor has a closed geometric structure, it can also be bulk molded through a mold. In this example, an inductor with a circular geometric structure is selected. The structure inside the cartridge is shown in Figure 11.

[0167] The inductor of this embodiment is fabricated in the following manner. Select a continuous sheet-shaped or cylindrical magnetic conductive material and determine whether the width and thickness of the sheet-shaped magnetic conductive material or the diameter of the cylindrical magnetic conductive material meet the requirements. If the requirements are not met, the material can be processed to meet the requirements. Specifically, the width of the sheet-shaped magnetic conductive material is 0.5 to 4 mm, the thickness is 0.01 to 0.2 mm, and the diameter of the cylindrical magnetic conductive material is 0.05 to 2 mm.

[0168] A sheet-shaped magnetic conductive material is used. The width of this magnetic conductive material can be changed smoothly and gradually within a certain range. The two long sides of this magnetic conductive material have a continuous sawtooth, continuous wave, or continuous gear shape. Multiple arc-shaped or rectangular grooves can also be evenly provided on both long sides of the magnetic conductive material.

[0169] When using a columnar magnetic conductive material, continuous threads may be formed on the surface of the magnetic conductive material by cutting, or a plurality of circular or rectangular grooves may be formed in the magnetic conductive material.

[0170] The continuous magnetic conductive material is cut to a predetermined length, which is set according to the length of the aerosol-forming substrate of the cartridge to be used, and is typically 1.5 to 4 times the length of the aerosol-forming substrate.

[0171] The magnetic conductive material obtained after cutting is placed in a mold and folded into the desired shape of the inductor, and the ends of the magnetic conductive material of the fabricated inductor are tightly joined to form a closed geometric shape.

[0172] In use, the fabricated inductor is loaded into the packaging of the cartridge using a loading device, and the aerosol-forming substrate is loaded into the packaging so as to completely surround the inductor. The loading device is preferably a push-type. Loading can be performed from either the distal end or the proximal end. Care must be taken when using the push-type loading device to prevent deformation of the inductor during loading.

[0173] As shown in Figure 32, the inductor allows this cartridge to be used in either a resistive or electromagnetic peripheral heated smoking device. Because the inductor is designed with a closed geometric structure, a heating pin or heating sheet must not be inserted into the tobacco cartridge when using a resistive or electromagnetic peripheral heated smoking device. Therefore, this cartridge is only suitable for peripheral heated smoking devices, not insertable heated smoking devices. [Example]

[0174] The first and second divided members each have an inner ring sealing portion and an outer ring fitting portion. The inner ring sealing portion and the outer ring fitting portion are separate parts of a single flexible sheet material. The inner ring sealing portion is the center of the single flexible sheet material and is circular. The diameter of the inner ring sealing portion is the same as the diameter of the inner tube of the packaging member. The entire outer ring fitting portion, except for the inner ring sealing portion, is made of flexible sheet material.

[0175] The outer ring fitting portion is also cut before being folded and integrally connected to the outer periphery of the inner ring sealing portion to form a ring shape, a continuous zigzag shape, a continuous wave shape, or a continuous gear shape, or portions thereof are connected to form a plurality of discontinuous protrusions on the outer periphery of the inner ring sealing portion.

[0176] When the outer ring fitting portion is integrally connected to the outer periphery of the inner ring sealing portion to form a ring, the first or second divided member is pushed by the pushing rod and attached or adhered to the inner tube wall of the packaging member, resulting in a wrinkled shape.

[0177] When the outer ring fitting portion is integrally connected to the outer periphery of the inner ring sealing portion in a sawtooth, wave, or gear-like shape, the first or second divided member may be wrinkled or flat after being pushed by the pushing rod and attached or bonded to the inner tube wall of the packaging member, depending on the area of ​​the cut portion.

[0178] When the outer ring fitting portion is partially connected and multiple discontinuous protrusions are formed around the inner ring sealing portion, the first or second divided member is pushed by the pushing rod and attached or adhered to the inner tube wall of the packaging member, resulting in a flat shape. The rest is the same as in Example 23. [Explanation of symbols]
