Description

Technical Field

[0001] The present invention relates to a heated aroma generating base material capable of generating an aerosol when heated, a heated aroma cartridge, and a method for manufacturing the heated aroma generating base material.

Background Art

[0002] The cartridge of a heat-not-burn smoking device has a heated aroma generating base material containing, for example, an aroma source material such as a tobacco plant or a non-tobacco plant that generates an aroma when heated, and an aerosol former that generates an aerosol when heated. This cartridge is generally heated by a heat-not-burn smoking device up to 200°C or higher when in use. After the temperature increase process of the heat-not-burn smoking device ends, the user inhales the aerosol generated from the cartridge.

[0003] The diffusion rate of the aroma, which is a volatile component of the aroma source material, is greater in the liquid phase than in the solid phase. Therefore, a wax or the like, which is a thermally fusible substance, is added to the heated aroma generating base material to promote the movement of the volatile components from the inside of the heated aroma generating base material to its surface when the heated aroma generating base material is heated.

[0004] As the heated aroma generating base material to which wax is added, for example, a heat-not-burn aerosol generating article is disclosed in Patent Document 1, which includes an aerosol forming matrix, and the aerosol forming matrix is a homogenized tobacco material containing tobacco and wax having a melting point of 50°C to 150°C, and the wax is uniformly distributed in the homogenized tobacco material.

Prior Art Documents

[0005] [Patent Document 1] Patent No. 6433626 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] However, in Patent Document 1, the heated aroma-generating substrate is made of wax from tobacco plants, non It is formed by impregnating aromatic materials such as tobacco plants. In other words, the fibrous structure of the aromatic material The wax has penetrated all the way to the weave. When the wax is impregnated into the fiber structure, a large amount of the wax is absorbed by the base material. It moves inward (towards the fibrous tissue). Therefore, much of the wax is in the base material. It is located more on the interior side than on the surface side. In this state, even if the wax melts due to heating... Furthermore, wax tends not to dissolve easily onto the surface of the heated fragrance-generating substrate. Because it dissolves along with its components, volatile components move from the inside of the heated fragrance-generating substrate to its surface. It will decrease by a minute.

[0007] Therefore, the heating process from ambient temperature or room temperature to the target heating temperature of the heated smoking device Initially, the content of aerosols of volatile aromatic components decreases. Therefore, The aerosol immediately after the heating process by a heated smoking device is complete contains sufficient aromatic components. This was not done, and users had the problem that they could not easily smell the fragrance immediately after the heating process was completed. Ta.

[0008] This invention has been made in view of the above problems, and is the immediate end of the heating process by a heated smoking device. A heated fragrance generating substrate capable of retaining sufficient fragrance in the subsequent aerosol, The objective is to provide a heating fragrance cartridge and a method for manufacturing a heating fragrance cartridge. . [Means for solving the problem]

[0009] The heated fragrance generating substrate of the present invention comprises a fragrance source material that generates fragrance when heated, an aerosol former that generates an aerosol when heated, and Therefore, it contains a thermally fused substance that melts, and is used to inhale aerosols containing aromatic components. In a heated fragrance generating substrate used in the above, the heat-meltable substance has a melting point of 50 to 100°C. It is characterized by being within a certain range and being dispersed in the heated aroma-generating substrate in a sea-island structure. Let's assume that.

[0010] The heated fragrance generating substrate of the present invention has a heat-fused decomposition material that forms a sea-island structure. It is dispersed within. In other words, the sea island structure is composed of components other than thermally fused materials. The islands are formed by thermally fused materials. Furthermore, the melting points of thermally fused materials are 50-100°C. It is in the range of °C. Therefore, the thermally molten material is in the initial stage of the heating process of the heated aroma-generating substrate. It melts in the heat. Aromatic components released from fragrance sources dissolve into the molten, heat-meltable substance. The heat-melting substance is dispersed in the heated fragrance-generating substrate, and at least on the surface of the heated fragrance-generating substrate... By forming islands with an island-sea structure, the thermally fused material includes tobacco plants, non-tobacco plants, etc. When melted, it becomes more fluid than when impregnated with the fragrance source material. Consequently, the heat melting The amount of dissolved material that moves along with the aromatic components to the surface of the heated aromatic-generating substrate when it melts also increases. Therefore, the aromatic components of the aerosol increase. In this stage, it becomes possible to generate an aerosol containing many aromatic components. Thus, the user can enjoy a rich aroma immediately after the end of the temperature rising process. Incidentally, if the melting point of the thermally fusible substance is less than 50°C, the thermally fusible substance may melt during a high temperature period such as summer, resulting in stickiness. Also, if the melting point of the thermally fusible substance exceeds 100°C, the thermally fusible substance may not be sufficiently melted at the initial [[ID=1 O]]stage of the temperature rising process of the heated aroma generating substrate, and there is a tendency for the

[0011] aroma of the aerosol immediately after the end of the temperature rising process to be insufficient. In the heated aroma generating substrate of the present invention, it is preferable that the thermally fusible

[0012] substance has a melting point in the range of 50 to 80°C. When the melting point of the thermally fusible substance is 50 to 80°C, it becomes easier to melt at the initial

[0013] stage of the temperature rising process of the heated aroma generating substrate, and the aroma can be further enhanced immediately after the end of the temperature rising process. In the heated aroma generating substrate of the present invention, it is preferable that the thermally fusible

[0014] substance is selected from beeswax, carnauba wax, petrolatum, and paraffin wax, and it is most preferable that it is beeswax. If the thermally fusible substance is selected from beeswax, carnauba wax, petrolatum, and paraffin wax, the thermally fusible substance becomes easier to melt at the initial stage of the temperature rising process of the heated aroma generating substrate, and the aroma immediately after the end of the temperature rising

[0015] In the heated fragrance generating substrate of the present invention, the heat-meltable substance contains a fragrance agent. preferable.

[0016] In the heated fragrance generating substrate of the present invention, an adsorbent capable of adhering to the fragrance agent is provided. It is preferable to include it.

[0017] By including an adsorbent capable of retaining the fragrance, the heating of the fragrance-generating substrate to be heated Even at the very end of the period during which smoking or aerosol inhalation is permitted, It is possible to maintain a high concentration of fragrance components of the fragrance contained in the aerosol. Because thermally fused substances become more easily fused in the early stages of the heating process, immediately after the heating process ends... This can enhance the fragrance, and the adsorbent helps maintain a high concentration of the fragrance components of the fragrance. Therefore, users can enjoy the aroma throughout the entire period during which they can smoke or inhale the aerosol. You can enjoy a wide variety of flavors.

[0018] When a heat-meltable substance contains a fragrance, in the initial stage of the heating process of the fragrance-generating substrate being heated... The heat-soluble substance dissolves, and the fragrance volatilizes, making it easier to release along with the aerosol. Therefore This allows for a greater enhancement of the aroma immediately after the heating process is complete.

[0019] In the heated aroma-generating substrate of the present invention, the thermally fused substance is contained in an amount of 2 to 20% by mass. This is preferable.

[0020] The thermally fused substance is present in a content of 2-20% by mass, and the thermally fused substance melts. This makes it easier to generate aromatic compounds.

[0021] In the heated aroma-generating substrate of the present invention, the aroma source material is derived from a non-tobacco plant. It is preferable to do so.

[0022] If the aromatic material is derived from a non-tobacco plant, it does not contain nicotine, therefore, The latter tends to seek stronger fragrances and stimulating sensations than when tobacco plants are used as the fragrance source. As described above, the heated fragrance generating substrate of the present invention generates a pleasant fragrance through the use of a heat-melted substance. Because this is possible, it can meet user expectations.

[0023] The heated fragrance cartridge of the present invention is attached to a suction device having an electrically heating means, and A heated fragrance cartridge generates an aerosol containing aromatic components when heated. In the case, a cylindrical cover and a housing at one end of the cover that is heated A heated fragrance generating substrate that generates an aerosol containing fragrance components, and the other end of the cover It comprises a filter housed on the side, and the heated fragrance generating substrate is any of the above. This product is characterized by the use of the heated aroma-generating substrate described in (c).

[0024] According to the heated fragrance cartridge of the present invention, by using the heated fragrance generating substrate, The user then attaches the heated fragrance cartridge to the inhalation device, heats it, and inhales the aerosol. From the very beginning, you can enjoy a rich aroma.

[0025] The present invention relates to a method for producing a heated fragrance-generating substrate, which generates fragrance when heated. A fragrance source material, an aerosol former that generates an aerosol when heated, and a heated A mixture of raw materials containing a heat-melting substance that melts upon heating is formed and heated to generate an aroma. A method for manufacturing a base material, wherein the thermally fused substance has a melting point in the range of 50 to 100°C. The material is added to the raw material using a powder form, and the raw material is melted by the thermally fused substance. The method is characterized by mixing and molding at a temperature below 1 / 20.

[0026] According to the method for producing a heated fragrance-generating substrate of the present invention, the heat-meltable substance remains in a sea-island structure. A heating-to-generate fragrance substrate is manufactured in such a manner. Therefore, a heat-meltable substance containing dissolved fragrance components is produced. It moves to the surface of the heated fragrance-generating substrate and becomes more easily volatile along with the aerosol former. Therefore, in the initial stages of the heating process of the heated aroma-generating substrate, many aroma components are released. It becomes possible to generate the contained aerosol. In addition, the user can use a heated smoking device. The rich aroma can be enjoyed immediately after the heating process is complete.

[0027] In the method for producing a heated fragrance-generating substrate of the present invention, the heat-meltable substance contains a fragrance agent. It is preferable to add the powdered form to the aforementioned raw materials.

[0028] By incorporating a fragrance into a heat-meltable substance, the heated fragrance cartridge can be used with an inhaler. When attached to the device and heated, the heat-soluble substance melts in the initial stages of inhalation, causing the fragrance to volatilize. Because it is released in this way, you can feel a richer aroma from the very beginning of inhalation. ru. [Effects of the Invention]

[0029] According to the heated aroma-generating substrate of the present invention, in the initial stage of the heating process of the heated aroma-generating substrate Therefore, it becomes possible to generate aerosols containing many aromatic components. Users can enjoy a rich aroma immediately after the heating process by the heated smoking device is complete. .

[0030] According to the heated fragrance cartridge of the present invention, since it includes the heated fragrance generating substrate of the present invention, Users can enjoy a rich aroma immediately after the heating process by the heated smoking device is complete.

[0031] According to the method for manufacturing a heated fragrance cartridge of the present invention, the raw material is a thermally fused substance with a melting point below the melting point. By mixing and molding at a certain temperature, the heat-meltable material remains in the form of a sea-island structure. As a result, the heat-meltable substance containing dissolved aromatic components moves to the surface of the heated aromatic generating substrate. Since it becomes more volatile along with the aerosol former, immediately after the heating process of the heated smoking device is complete. You can enjoy the rich aroma later on.

[Modes for carrying out the invention]

[0033] Hereinafter, with reference to the drawings, a heated fragrance cartridge using the heated fragrance generating substrate according to the present invention An embodiment of the cartridge will be described. Figure 1 shows the heated fragrance cartridge according to this embodiment. Figure 2 is a perspective view. Figure 2 is an exploded perspective view of the heated fragrance cartridge according to this embodiment. Figure 3 is a cross-sectional view of the heated fragrance cartridge along line AA in Figure 1.

[0034] [Configuration of the heated fragrance cartridge] As shown in Figures 1 and 2, the heated fragrance cartridge 100 is, for example, a heated smoking device. It can be used in cartridges, etc. Hereinafter, the heated fragrance cartridge 100 is electrically... Used in heated smoking devices (hereinafter also simply referred to as "suction devices") which are suction devices having a heating means. Let me explain an example of a cartridge that can be used.

[0035] The heated fragrance cartridge 100 consists of a cylindrical cover 10 and a container housed at one end of the cover 10. A heated fragrance generating substrate 20, a filter 30 housed on the other end of the cover 10, and a cover -10 is housed in and is positioned between the heated aroma-generating substrate 20 and the filter 30. It comprises material 40 and

[0036] In this embodiment, the cover 10 is formed in a cylindrical shape. The shape is not particularly limited if available. The cover 10 may be formed in, for example, a polygonal prism shape, a rectangular parallelepiped shape, etc. It's okay if it's not allowed.

[0037] The cover 10 consists of a wrapping paper 11 that covers the heated fragrance generating substrate 20, and a heating element that is heated from the outside of the wrapping paper 11. A base material 12 that covers the fragrance generating base material 20, the support member 40 and the filter 30, and the outside of the base material 12 It is composed of a base material 12 and a chip paper 13 that further covers the outer periphery of the filter 30. The roll paper 11 and the chip paper 13 are joined to each other by means of adhesive or heat fusion.

[0038] The wrapping paper 11, base material 12, and chip paper 13 can be, for example, paper, synthetic resin film, or metal. It can be constructed using foil, etc., and may even be a composite sheet made by laminating these materials. Furthermore, the inner surfaces of the wrapping paper 11, base material 12, and chip paper 13 have adhesive layers and hot mesh A bondable or fused layer, such as a tack layer, may be formed.

[0039] In this embodiment, the rolled paper 11 is formed by collectively arranging the heated aroma-generating base material 20 into a columnar shape. It plays a role. The base material 12 connects the heated aroma-generating base material 20, the support member 40, and the filter 30. It plays a connecting role. The chip paper 13 is used by the user to hold the heated fragrance cartridge 100 in their mouth. It serves to reinforce the part that is held in the mouth (mouthpiece). The cover 10 is made of rolled paper 11 and base This is not limited to cases where the material 12 and the chip paper 13 are composed separately, for example It consists of a single sheet in which the wrapping paper 11, base material 12, and chip paper 13 are integrated. It's fine if you do that.

[0040] In this embodiment, as shown in Figures 2 and 3, the heated fragrance generating substrate 20, the support part Material 40 and filter 30 are arranged axially from one end to the other of the cover 10. It is installed.

[0041] The heated aroma-generating substrate 20 can be, for example, rod-shaped, strip-shaped, powder-shaped, granular, pellet-shaped, or small This invention is an aggregate of flake-like, sheet-like, fibrous, porous, or block-like components. In terms of form, the heated aroma-generating substrate 20 is cylindrical as a whole, composed of strip-shaped components. It is formed in that shape.

[0042] The heated aroma-generating substrate 20 is heated by the electrical heating means of the heated smoking device. This makes it possible to generate aerosols. The heated aroma-generating substrate 20 is a The process involves using aromatic materials derived from non-tobacco plants, not just boxwood, to generate aerosols. It contains an aerosol former that can be formed and a thermally fused substance that melts when heated. The following will be used. The composition of the heated aroma-generating substrate 20 will be described later.

[0043] The filter 30 is used to filter the mainstream smoke or aerosol generated from the heated fragrance generating substrate 20. It has a certain degree of breathability and captures solid particles contained in mainstream smoke or aerosol, A filter having the function of adsorbing harmful components is preferably used. The shape of the filter 30 is There are no particular limitations; any shape that can be wrapped by cover 10 is acceptable.

[0044] Examples of filter 30 include acetate filters using acetate fibers, acetate A charcoal filter containing activated carbon in the filter, covering the outer surface of filter 30. An AFT (Advanced Filter) having multiple grooves formed as recesses along the axial direction. Technology such as can be used. In addition, the filter 30 contains fragrance and microcells. It may contain processed fragrances, etc. In this embodiment, the filter 30 is a cover -10 is fixed to the inner circumferential surface of the base material 12 by means of fixing such as adhesive or welding.

[0045] As shown in Figures 2 and 3, the support member 40 connects the heated aroma-generating substrate 20 and the filter 3 It is located between 0 and and is positioned adjacent to each of them. The support member 40 is inside the cover 10 The shape may have an outer circumferential surface that corresponds to the shape of the circumferential surface. In this embodiment, the support member 4 0 is formed in a cylindrical shape overall. The support member 40 is bonded or welded to the cover 10. It is fixed by a fixing means, and in this embodiment, it is fixed to the inner circumferential surface of the base material 12.

[0046] The support member 40 has a structure that allows air to pass from one end to the other end, and is heated to generate fragrance. The shape of the base material 20 is not limited as long as it has a function to restrict its movement to the other end.

[0047] In this embodiment, the support member 40 has one or more ventilation passages 4 that penetrate it in the axial direction. It has 1. In this embodiment, the ventilation passage 41 is on the outer circumferential surface of the support member 20, Four concave grooves formed at equal intervals in the direction and along the axial direction, and on the inner circumferential surface of the cover 10 Therefore, it is defined.

[0048] Furthermore, the ventilation passage 41 penetrates axially, for example, from one end face to the other end face of the support member 40. The ventilation passage 41 may consist of one or more through holes formed to allow air to pass through. For example, a central ventilation passage formed along the axis of the support member 40, and surrounding this central ventilation passage Multiple vents are arranged in a circumferential direction and also formed to penetrate axially. It may consist of roads.

[0049] Furthermore, the support member 40 has a hexagonal end face shape and multiple ventilation passages that penetrate in the axial direction. It may be composed of a honeycomb structure or the like. Furthermore, the support member 40 may be, for example, a continuous air It may be composed of a porous body in which bubbles are formed.

[0050] The support member 40 is located on one or both axial end faces of the cover 10, preferably on the heated aroma At the end face located on the generating substrate 20 side, when the electrically heating means of the suction device is inserted, The cover 10 of the heated fragrance generating substrate 20 has a shape that can restrict its axial movement. This is preferable. Here, the axial movement of the cover 10 of the heated aroma-generating substrate 20 can be restricted. A suitable shape means, for example, that the movement of the material of the heated aroma-generating substrate 20 does not cause practical problems. Any shape that can be restricted is acceptable.

[0051] Because the support member 40 is formed in this manner, the heated aroma generation of the heated smoking device An electric heating means for heating the base material 20 is inserted from one end of the heated fragrance cartridge 100. When this happens, the support member 40 restricts the movement of the heated fragrance-generating substrate 20 to the other end. Therefore, the support member 40 can support the heated aroma-generating substrate 20.

[0052] Furthermore, the support member 40 contains the fragrance components generated from the heated fragrance generating substrate 20. As the aerosol passes through, the high-temperature aerosol can be cooled. Therefore, the support part Material 40 has heat resistance corresponding to the combustion temperature or heating temperature of the heated fragrance cartridge 100. It is formed by a component that is heated. For example, the heated fragrance cartridge 100 is heated by a heated tobacco If it is a cartridge for a component, the support member is a material with heat resistance of approximately 200 to 350°C. It would be good if it were formed in that way.

[0053] Examples of such materials include paper, resin, rubber, wood, metal, and ceramics. While these are some examples, it is more preferable that the resin be moldable into various shapes.

[0054] The resin may be either a thermoplastic resin or a thermosetting resin, for example, polyolefin Polystyrene resins, polyester resins, polystyrene resins, nylon resins, acrylic resins Fat, silicone resin, fluororesin, polyurethane resin, ethylene-vinyl acetate (EV) A) Resins, phenolic resins, amino resins, ABS resins, and biodegradable plastics Examples include bucks, etc. Among these resins, the heated fragrance cartridge 100 is used Since it becomes waste after use, biodegradable plastics are preferable from the perspective of protecting the natural environment. .

[0055] Examples of biodegradable plastics include poly(3-hydroxybutyrate) (PHB) , poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), Other examples include polylactic acid (PLA), etc.

[0056] The heated fragrance generating base material 20 of the heated fragrance cartridge 100 is connected to a suction device (not shown). It is heated by an electric heating means to a target temperature of 200°C or higher from room temperature or ambient temperature. Therefore, the heated aroma-generating substrate 20 is heated from room temperature or ambient temperature to the target heating temperature. The process involves the user immediately after the heating process is complete, and then the heated fragrance cartridge 10 It becomes possible to inhale aerosols emitted from zero.

[0057] [Composition of the heated fragrance generating substrate 20] The heated fragrance generating substrate 20 includes a fragrance source material that generates fragrance when heated, and An aerosol former that generates an aerosol when heated, and It contains a thermally fused substance that melts upon contact with the elements.

Including these is appropriate for providing users with a pleasant fragrance, but it is not limited to these. No.

[0061] However, when the heated fragrance cartridge is attached to the inhalation device, the heated fragrance cartridge Fragrance is defined as the scent emanating from the product itself, and the heated fragrance cartridge is heated. Sometimes, aroma is defined as a scent that floats in the air, and sometimes, heating the heated fragrance cartridge creates an aerosol. It is preferable that it possesses the three elements of flavor, which is defined as the aroma that lingers in the mouth when inhaled. It's nice.

[0062] As a fragrance, it includes Chinese tea, black tea, rose, and the Osmanthus fragrans plant (Osmanthus species).

It is preferable that it includes at least one of the following:

[0063] In terms of aroma, it is the underground of shallots, garlic, onions, and konjac. Stems, and at least one selected from the above-ground stems and leaves of the tobacco plant of the Solanaceae family, genus Tobacco. It is preferable that the above be included.

[0064] The flavor comes from quince and plants of the citrus genus (such as bitter orange and Satsuma mandarin). Summer orange, Ponkan orange, Hassaku orange, Iyokan orange, I-chan lemon, Trifoliate orange, Orange The Mandarin Orange, Kabosu, Kishu Mandarin, Chinotto, Grapefruit, Kou Ji Sanbokan Citron Jabara Sudachi Tachibana Tangor Natsumikan Hanayuzu, Hyuga Natsu, Hirami Lemon (Shikuwasa), Buntan (Zabon), Yuzu Lime, lemon, kaffir lime, etc., plants of the genus Prunus in the Rosaceae family, apple, pineapple Mango, kumquat, melon, pomegranate, plum, apricot, blueberry, Rosaceae, Netherlands Plants of the Strawberry genus, raspberries, bananas, grapes, and peppermint varieties of the Mentha genus in the Lamiaceae family.

[0066] (thermally fused material) The thermally molten material has a melting point in the range of 50 to 100°C, preferably in the range of 50 to 80°C. The melting point of the thermally fused material is less than 50°C. If present, there is a risk that the heat-melting substance will dissolve during periods of high temperatures, such as in the summer, causing stickiness. Yes. Also, if the melting point of the heat-soluble material exceeds 100°C, the heating process of the heated fragrance-generating substrate is affected. In the initial stages, the thermally fused material is not sufficiently melted, immediately after the heating process by the heated smoking device is completed. The aerosol tends to lack fragrance.

[0067] Furthermore, the melting point of a thermally fused substance is, for example, that of paraffin wax as specified in JIS K2235. It can be measured in accordance with the melting point measurement method of S. That is, by using a predetermined melting point tester. Place the molten sample into a test tube and read the reading on the melting point thermometer every 15 seconds. The melting point is measured at the temperature when the temperature drop is within a certain range (when the difference is within 0.1°C for 5 consecutive times). It can be determined.

[0068] The thermally fused material is preferably in powder form. The average particle size of the thermally fused material is 125-35. It is preferably 5 μm, more preferably 150-300 μm, and 180- A particle size of 250 μm is even more preferable. The average particle size is determined, for example, by laser diffraction particle size analysis. It can be measured by a distribution measuring device, etc. In this invention, the average particle size is defined as med This refers to the diameter of Ahn.

[0069] If the average particle size of the thermally molten material is too large, its total surface area becomes small, thus reducing its contact with the heat source. The opportunity decreases. As a result, the thermally molten material is not sufficiently melted, and immediately after the end of the heating process... The concentration of aromatic components in aerosols tends to decrease.

[0070] If the outer diameter of the molten material is too small, the molten material will not separate into the heated fragrance generating substrate 20, as described later. It becomes difficult to form scattered sea-island structures. As a result, each of the thermally fused materials aggregates into clumps. Because it exists as a substance in the heated aroma-generating substrate 20, the melting rate decreases upon contact with the heat source. A region is created, and the concentration of aromatic components in the aerosol decreases immediately after the heating process is completed. There is a direction.

[0071] The heat-meltable substance is present in the heated aroma-generating substrate 20 in an amount of 2 to 20% by mass, preferably 3% by mass. It is preferable that it contains 15% by mass, more preferably 5 to 15% by mass.

[0072] The proportions of fragrance source material, aerosol former, and heat-melting substance are determined by the volatilization of smoke and fragrance components. To balance the quantities, 55-75% by mass, 20-40% by mass, and 2-1% respectively. Preferably 5% by mass, 60-70% by mass, 25-35% by mass, 3-10% by mass It is preferable that it be so.

[0073] A thermally molten substance is a non-Newtonian fluid that, when heated, exhibits a melting point or softening point. The term is not particularly limited as long as it refers to "organic compounds that become waxy." Thermally molten substances are generally waxy. Organic compounds referred to as waxes are preferred, and typical examples of waxes and waxes are petroleum-based natural compounds. Waxes, synthetic waxes, plant-based natural waxes, and animal-based natural waxes can be used. Rosin, which is also used as a wax, is part of various tackifiers (adhesives). ) can be used. These can be used individually, or selected from among them. It can also be used as a mixture containing at least one of the following:

[0074] As a thermally molten substance, plant-based natural waxes and other materials are preferred due to their desirable melting point and flavor-enhancing properties. Animal-derived natural waxes are preferred. Examples of plant-derived natural waxes include sumac wax and lacquer wax. Carnauba wax, sugarcane wax, palm wax, candelilla wax, etc. can be used. In addition, natural animal waxes such as beeswax, whale wax, privet wax, wool wax, and shellac are used. This makes it possible to obtain materials with a melting point in the range of 50 to 100°C as defined in this invention. Furthermore, since it has a pleasant flavor of its own, it can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly noteworthy. Preferably, beeswax with a melting point of 62-65°C and rich in aromatic components is preferred.

[0075] Plant-based and animal-based natural waxes are mainly composed of esters of fatty acids and aliphatic alcohols. Yes. Plant-based and animal-based natural waxes are composed of fatty acids with various carbon numbers and aliphatic alcohols.

Therefore, plant-based natural waxes and animal-based natural waxes have a wide molecular weight distribution and a wide melting point temperature. It has a wide temperature range and is characterized by high viscosity when melted.

[0076] Petroleum-based natural waxes are hydrocarbon compounds, therefore they contain aromatic components and aerosol forms. It has the advantage of having minimal interaction with other substances and being less likely to negatively affect flavor. Examples of waxes include petroleum jelly, paraffin wax, and microcrystalline wax. Camphor wood and the like can be used as preferred materials.

[0077] These petroleum-based natural waxes differ in their melting point temperature range based on their molecular structure. (Vaseline) It is a mixture of branched hydrocarbons and alicyclic hydrocarbons, with a melting point temperature range of 36-60°C. It's spacious.

In particular, metallocene catalyst polyolefin waxes are more preferred due to their narrow molecular weight distribution. For example, "Excellex (registered trademark)" manufactured by Mitsui Chemicals, Inc., which is a metallocene catalyst PE wax. "Standard" has a narrow molecular weight distribution and compositional distribution, and therefore has a melting point of 89-128°C, but is not suitable for hot melting. It has a low melt viscosity upon dissolution, making it an excellent polyolefin-based wax.

[0085] In addition to the above, other thermally fused substances include fatty acid amides, fatty acids, and aliphatic alcohols. Other types can also be used. Suitable fatty acid amides include monoamides and bisamides. Examples of monoamides include stearic acid monoamide, oleic acid monoamide, and erucic acid monoamide.

[0089] These higher fatty acids and higher aliphatic alcohols are the terminals of linear hydrocarbons, respectively. These are compounds to which carboxyl groups and hydroxyl groups are bonded, and which have no molecular weight distribution or molecular weight distribution. The cloth is extremely narrow. Therefore, like paraffin wax, it has a low melt viscosity when heated and melts, and a low melting point. The narrow temperature range also promotes deformation and flow of the heated fragrance generating substrate 20 during heating. It has a significant effect.

[0090] Polyoxyalkylene glycols have an average molecular weight of 6. Materials with a melting point of 00 to 11,000 are preferable because they have a low melting point and low melt viscosity during thermal melting. Furthermore, polyethylene glycol-polypropylene glycol block polymer, The glycol unit content is 40-80 wt%, and the average molecular weight is 3,000-13,000. It is preferable that it be 00. Polyoxyalkylene glycols that satisfy this requirement are non-I It is also used as an ionic surfactant, but its molecular weight distribution is narrow and its melting point temperature range is Because it is narrow, it has excellent fluidity when melted by heat.

[0091] Polyoxyethylene alkyl ethers include polyoxyethylene monomethyl ether A tel with an average molecular weight of 1,000 to 4,000 is preferred. This is also a nonionic interface. Although it is used as an activator, it has a narrow molecular weight distribution and a narrow range of melting point temperatures. It exhibits excellent fluidity during thermal melting.

The amount of the agent is based on 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally fused substance. If the percentage is less than 3% by mass, the fragrance components generated from the fragrance agent are not sufficiently contained in the aerosol. It tends to become difficult to do so. Also, the amount of fragrance, fragrance source material, aerosol form When the total amount of molten material and heat-melting material exceeds 25% by mass, the heated aroma-generating group The strength of material 20 tends to decrease.

[0098] (Molding agent) The molding agent is used to reinforce the heated aroma-generating substrate 20. Examples of molding agents include: For example, cellulose fibers, microcrystalline cellulose, etc., can be used.

[0099] Examples of cellulose fibers include sugarcane, bamboo, wheat, rice, esparto, and jus. Cellulose fibers such as cellulose, hemp, and wood are preferably used. The fiber diameter is preferably 5 to 25 μm, and the fiber length is preferably 0.25 to 6 mm. By using cellulose fibers with a fiber diameter and fiber length within such a range, the heated aroma generating group This makes it possible to enhance the binding effect of the constituent components of material 20.

[0100] Furthermore, the microcrystalline cellulose preferably has an average particle size of 70 to 120 μm. When the average particle size of crystalline cellulose is less than 70 μm, the shrinkage of the heated aroma-generating substrate 20 is suppressed. Furthermore, it tends to become difficult to prevent adhesion between the heated aroma-generating substrate 20 and the molding machine. Yes. When the average particle size of microcrystalline cellulose exceeds 120 μm, the heated aroma-generating substrate 20 It tends to break easily. The average particle size of microcrystalline cellulose is determined by laser diffraction particle size analysis. It can be measured by a fabric measuring device. In this invention, the average particle size is the median diameter. This shall mean...

[0101] Furthermore, the mass-average molecular weight (Mw) of microcrystalline cellulose is between 20,000 and 60,000. It is preferable that the mass-average molecular weight (Mw) of the microcrystalline cellulose is less than 20,000. If present, the effect of suppressing the shrinkage of the heated aroma-generating substrate 20 tends to be diminished. When the mass-average molecular weight (Mw) of cellulose exceeds 60,000, the heated aroma-generating substrate... Number 20 tends to break more easily.

[0102] The molding agent is composed of 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally fused substance. It is good if it contains 2 to 25% by mass, preferably 3 to 20% by mass. By incorporating the morphing agent into the heated aroma-generating substrate 20 in this manner, the above function is achieved. In addition to fulfilling this purpose, the molding agent does not hinder the generation of volatile substances from the fragrance source and aerosol former. This can prevent [the following].

[0103] (Binder) The binder consists of the fragrance source material, aerosol former, and thermally fused substance that make up the heated fragrance generating substrate. It is used to bind together raw materials such as materials. Examples of binders include polysaccharide polymers. Cellulose polymers and the like can be used.

[0104] Examples of polysaccharide polymers include konjac mannan (glucomannan) and guar gum.

Cellulose polymers are suitable for heating the aroma-generating substrate 20 in terms of strength and moldability. Sodium salt of CMC, potassium salt of CMC, sodium carboxyethylcellulose Salts, specifically potassium salts of carboxyethylcellulose, are preferred.

[0106] It is preferable to use a combination of polysaccharide-based polymers and cellulose-based polymers as binders. In this case, the polysaccharide polymers include glucomannan, guar gum, and tamarind gum. It is preferable to use locust bean gum. Furthermore, as a cellulose polymer, , sodium salt of CMC, potassium salt of CMC, sodium carboxyethylcellulose It is preferable to use potassium salts of carboxyethylcellulose. By using polysaccharide polymers and cellulose polymers in combination, a heating-to-aroma-generating substrate 2 This can improve the strength and moldability of the material.

[0107] The binder is applied to 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally fused substance. It is preferable that it contains 5 to 30% by mass, and 8 to 28% by mass. This is more preferable. The binder is contained in the heated aroma-generating substrate 20 in such a quantity. This improves the strength and moldability of the heated aroma-generating substrate 20, and allows for the creation of aromas. This makes it possible to avoid adverse effects such as the generation of volatile substances from fragrance sources and aerosol formers.

[0108] Furthermore, the heated aroma-generating substrate 20 of the present invention contains both a binder and a molding agent. It is preferable that the binder and molding agent are mixed in a mass ratio of 1:1 to 1:2. A value of 5 is preferable in terms of cohesion.

[0109] (Adsorbent) If the fragrance is not contained in the heat-melting substance, the temperature of the heated fragrance generating substrate 20 of the fragrance will be affected. This prevents the aerosol former and fragrance source from volatilizing before they reach the optimal temperature for volatilization. To achieve this, it is advisable to use an adsorbent. As described above, the adsorbent is used to add fragrance to the heated fragrance generating material 20. It can be used to retain fragrances.

[0110] The adsorbent can be used in various ways depending on the manner in which a compound such as a fragrance is adsorbed onto the fragrance generating substrate 20. Various materials can be used. For example, by encapsulating the compound, a fragrance-generating substrate can be used. An adsorbent that adheres to 20 can be used, and such an adsorbent is cyclodex. Trin can be used.

[0111] Cyclodextrins are chemical substances containing hydroxyl groups and carboxyl groups of various sizes. It is known to form cyclodextrins, and among α, β, and γ-cyclodextrins, Displacement can also be used. In particular, β-cyclodextrin can be used with menthol and inclusion compounds. It forms a structure that is ideal as an sorbent for menthol.

[0112] When cyclodextrin is used as an adsorbent, the adsorbent is a fragrance source, aerosol former Furthermore, it is generally considered that the content is 0.1 to 1.2% by mass relative to 100% by mass of the total amount of thermally fused material. It is more preferable that it contains 0.2 to 1.0% by mass.

[0113] Furthermore, an sorbent is used that adsorbs the compound and causes it to adhere to the fragrance generating substrate 20. It is also possible. For example, if the compound in question is menthol, then menthol is phenol It has phenolic hydroxyl groups. Therefore, as an adsorbent, it can adsorb phenolic hydroxyl groups. Possible methods include using hydrophilic crosslinked polymers such as crosslinked polyvinylpyrrolidone (PVP). It is possible.

[0114] Furthermore, for example, if the compound in question is nicotine, nicotine is a five-membered heterocyclic ring containing nitrogen. It has a compound of the formula. Therefore, as an sorbent, it is mutually exclusive with nitrogen-containing 5-membered heterocyclic compounds. Cross-linked PVP, which is thought to form an effect, can be used.

[0115] When cross-linked PVP is used as the adsorbent, the adsorbent consists of an aromatic source material, an aerosol former, and a heat fusion agent. It is preferable that the content be 4 to 25% by mass, relative to 100% by mass of the total amount of the dissolved material, and 5 to 20% by mass It is more preferable that it contains % Furthermore, the adsorbent contains both cross-linked PVP and cyclodextrin. It is preferable.

[0116] (Preservative) To preserve heated fragrance-generating cartridges for extended periods, it is advisable to use preservatives. For example, potassium sorbate and / or sodium benzoate can be used as the agent. Yes, it is possible. The preservative consists of a total of 100g by mass of fragrance source material, aerosol former, and heat-melting substance. It is preferable that it contains 0.005 to 0.04 mass% relative to the total percentage.

[0117] (Surface configuration of the heated aroma-generating substrate 20) Figure 4 schematically shows the form of the heat-melted substance HS contained in the heated aroma-generating substrate 20. As shown in Figure 4, the heat-melting substance HS forms a sea-island structure within the heated aroma-generating substrate 20. They are distributed.

[0118] In this sea-island structure, the sea is composed of components other than the thermally fused material HS, and the thermally fused material HS Thus, an island is formed. In other words, the heat-melting substance HS is within the heated aroma-generating substrate 20. It exists as a block that defines a certain area.

[0119] The sea-island structure is also formed on the surface and within the heated aroma-generating substrate 20. Therefore, the surface of the heated aroma-generating substrate 20 has a sea-island structure as shown in Figure 4. Furthermore, the cross-section when the heated fragrance-generating substrate 20 is cut at any position is shown in Figure 4. It has a sea-island structure of a certain type.

[0120] Furthermore, as mentioned above, the melting point of the thermally fused substance HB is in the range of 50 to 100°C. Therefore, the heat-melting substance HS melts in the early stages of the heating process of the heated aroma-generating substrate 20. The aromatic components released from the aromatic source material dissolve into the molten, heat-meltable substance HB.

[0121] The heat-melting substance HS forms islands in a sea-island structure within the heated aroma-generating substrate 20, When the heated fragrance generating substrate is heated and the heat-melting substance HS melts, the fragrance is released from the fragrance source material. The ingredients, including the fragrance components of the air freshener, dissolve in the molten thermally fused substance HS, and combine with the thermally fused substance HS. It becomes easier to flow together.

[0122] The molten thermally melted substance HS flows within the heated aroma-generating substrate 20 and forms an aerosol former. Upon contact, the aromatic components are incorporated into the aerosol former and volatilize as an aerosol. Therefore, in the initial stages of the heating process of the heated aroma-generating substrate 20, many aroma components are present. This makes it possible to generate aerosols. Therefore, the user can use heated smoking devices. The rich aroma can be enjoyed immediately after the heating process is complete.

[0123] Next, the method for manufacturing the heated fragrance generating substrate 20 will be described. Figure 5 shows the heated fragrance This shows one embodiment of the manufacturing process for the generating substrate 20. As shown in Figure 5, the fragrance source material and heat Raw material (A) mixed with a molten substance, raw material (B) which is cellulose fiber as a binder, and Aerosol formers, fragrances, molding agents, binders (excluding cellulose fibers), adsorbents, preservatives A mixing process is carried out in which raw material (C), which is a mixture of the agent and pure water, is mixed. The mixing process involves thermal melting. The process is carried out below the melting point of the substance. The mixing process can be carried out, for example, using a known mixer. Cut.

[0124] Raw materials (A) consist of aromatic material that has been dried, insect-killed, and then crushed, and crushed heat-melted material. The mixture is compressed and sheared and mixed, and the compressed and sheared mixture is cooled to below 0°C and then pulverized. It can be obtained by doing so.

[0125] Raw material (B) is made by crushing compressed cellulose fibers and boiling the crushed cellulose fibers. It is obtained by crushing the dehydrated and dried material after the process is complete. Note that the raw material (B) is optional. It is a raw material used in [the product / service].

[0126] The raw material (C) is an aerosol former, along with a fragrance and a molding agent (cellulose fiber). Any of the following can be used (excluding fiber), binders, adsorbents, preservatives, and pure water. .

[0127] By performing the mixing process in this manner, the fragrance source material is mixed into the heated fragrance generating substrate 20. The combined thermally fused powder can form a dispersed sea-island structure.

[0128] Next, the mixture obtained in the mixing process is compressed and sheared to form a sheet. It is carried out. In compression and shearing processes, for example, it can be done using a three-roll system. By using a three-roll compression and shearing process, air is trapped, preventing water evaporation. It can be molded into a sheet-like shape.

[0129] The sheet obtained in this way has a porous structure that contains air inside. As a result, it becomes possible to obtain a heating-to-heat aroma-generating substrate 20 with low density. Because the rolls of a three-roll machine have extremely flat surfaces, the surface of the sheet is formed flat. .

[0130] That is, the heated aromatic generating base material 20 contains air inside during compression / shearing processing and has a porous structure, so it has a low density, and its surface is formed flat without unevenness to become.

[0131] The mixture formed into a sheet shape by compression / shearing processing is cut into a predetermined shape and size and a cutting process is performed. The sheet-like mixture is processed into, for example, a strip shape.

[0132] The mixture cut into a predetermined shape and size is placed on the cover 10 together with the filter 30 and the support member 40. Then, the cover 10 is rolled up so as to wrap these, and the ends of the cover 10 are fixed to manufacture the heated aromatic cartridge 100 .

[0133] In this way, the mixing process, the compression / shearing process, and the cutting process are performed below the melting point of the heat-melting substance to prevent it from spreading throughout the heated aromatic generating base material 20 due to the melting of the heat-melting substance, and it becomes possible to maintain the sea-island structure of the heat-melting substance in the heated aromatic generating base material 20 to be.

[0134] When a sea-island structure in which the powder of the heat-melting substance mixed with the aromatic source material is dispersed is formed in the heated aromatic generating base material 20, the heat-melting substance is dispersed and arranged in an island shape in the heated aromatic generating base material 20 to become.

[0135] ​​​​​​​When touched, the aromatic components become more easily volatile by forming aerosols together with the aerosol former. It is possible.

[0136] As a result, it is possible to efficiently volatilize the aromatic components of the fragrance source material. The aroma is emitted from the heated fragrance cartridge 100 immediately after the heating process of the heated smoking device is completed. When the aerosol is inhaled, the aroma can be enjoyed more fully.

[0137] Furthermore, the fragrance may be added to the raw material (A). Figure 6 shows the heated fragrance generating substrate. The 20th manufacturing process is shown in other embodiments. As shown in Figure 6, the fragrance is added to the raw material (A) When adding, for example, heat the powdered heat-melting substance and fragrance at a temperature above the melting point of the heat-melting substance and mix. After cooling, the mixture is crushed to a predetermined size, and the crushed material is mixed with powdered aromatic material. It is best to compress and shear the two materials together.

[0138] Furthermore, the manner in which the fragrance is added to the raw material (A) is not limited to this, for example, one of the fragrances Part or all of it may be added during the compression and shear mixing of raw material (A). By adding a fragrance to the raw material (A), the user can enjoy the fragrance emitted from the fragrance. The flavors can be fully appreciated immediately after the heating process is complete.

[0139] As described above, according to the heated fragrance generating substrate 20 of the present invention, the heated fragrance generating substrate 20 In the initial stages of the heating process, it is possible to generate an aerosol containing many aromatic components. It becomes possible.

[0140] According to the heated fragrance cartridge 100 of the present invention, since it includes a heated fragrance generating base material 20, After the heating process of the heated smoking device ends, the user can fully enjoy the rich aroma.

[0141] According to the manufacturing method of the heated flavor cartridge 100 of the present invention, the heat-melting substance forms an island structure so that it remains, making the heat-melting substance more fluid, and the generated flavor components dissolve in the heat-melting substance, enabling the flavor components to easily flow out together with the aerosol.

[0158] (Creation of comparative examples) A comparative example of a heated fragrance cartridge was prepared using the formulation shown in Table 2. The comparative example is a thermally fused substance. The difference from the examples is that it does not contain the fragrance source material and aerosol phosphate. In other words, the basic formulation is made up of fragrance source material and aerosol phosphate. The formula was as follows: 70% by mass of fragrance source material and 3% aerosol former. The mass percentage was set to 0%. Since the other aspects are the same as in the example, the explanation of the raw materials and manufacturing method is omitted. ru.
