Description

Non-combustible heated flavor aspiration article and non-combustible heated flavor aspiration system

The present invention relates to a non-combustible heated flavor inhalation article and a non-combustible heated flavor inhalation system.

In combustion flavor inhalation articles (cigarettes), the flavor is tasted by burning a tobacco rod containing a tobacco filling. As a replacement for the combustion flavor absorption article, a non-combustion heated flavor absorption article has been proposed in which the flavor is tasted by heating the tobacco rod instead of burning it. In non-combustion heated flavor inhalation articles, for example, a tobacco rod is electrically heated to 200 to 400° C. to volatilize the tobacco flavor components and the user inhales them. The tobacco rod can be formed by wrapping the tobacco filling into a cylindrical shape with a paper wrapper or the like. For example, dried tobacco plants (mainly dried tobacco leaves) are crushed and mixed to form a sheet with a thickness of 100 to 500 ㎛, cut to 1 mm in width and 3 to 10 mm in length, and recommended as a paper wrapper. can be formed. Alternatively, it can be formed by crimping and gathering the sheets without cutting the molded product and recommending it as a paper wrapper. The moisture content of the tobacco filling may be 10 to 15% by mass, which is the equilibrium moisture under the normal environment of the dry tobacco itself. Tobacco fillings may contain, in addition to the tobacco plant, various volatile flavoring agents. Additionally, the tobacco filling may contain an aerosol-generating substrate such as glycerin or propylene glycol. The aerosol-generating substrate volatilizes when the tobacco rod is heated, cools to the cooling segment disposed downstream of the tobacco rod during the user's inhalation process, liquefies, becomes an aerosol, and is supplied into the user's mouth. Since the aerosol is supplied to the user along with tobacco flavor components, the user can taste sufficient flavor. A tobacco rod provided with a tobacco filling containing such an aerosol-generating substrate may also be referred to as an aerosol-generating rod.

As a heating method for a non-combustible heated flavor absorption article that electrically heats the aerosol generating rod, for example, a method of heating the outer periphery of the aerosol generating rod (for example, patent document 1), heating the inside of the aerosol generating rod. A method (for example, patent document 2) can be mentioned. On the other hand, Patent Documents 3 and 4 disclose an aerosol-generating rod having two segments as an aerosol-generating rod for a non-combustible heated flavor absorption article.

Patent Document 1: Japanese Patent Publication No. 2019-523639 Patent Document 2: Japanese Patent No. 6000451 Publication Patent Document 3: International Publication No. 2019/105750 Patent Document 4: International Publication No. 2019/110747

As described above, among the tobacco rods (aerosol-generating rods), both combustion flavor absorption articles and non-combustion heated flavor absorption articles, the vapor pressure of tobacco flavor components, fragrance components, aerosol-generating substrates, moisture, etc., which are composed of many types of substances. and many components with different boiling points are included.

Here, in the combustion flavor inhalation article, the tip of the tobacco rod is ignited and the combustion part (combustion cone) burns with use, so the heated area is approximately 800°C. The only tobacco filling is located immediately downstream of the combustion cone. For this reason, at each timing of use, regardless of whether it is the first or second half of use, low-boiling point components to high boiling point components are supplied to the user in a balanced manner.

On the other hand, in non-combustible heated flavor-absorbing articles, heating is usually continuously performed along the entire longitudinal direction of the aerosol-generating rod, so components with low boiling points (components with high vapor pressure) such as tobacco flavor components in the aerosol-generating rod are consumed throughout use. Volatilization is complete, and most of it is supplied to the user throughout use. On the other hand, components with high boiling points (components with low vapor pressure), such as aerosol-generating materials, are mainly supplied in the later stages of use. In this way, low boiling point components are mainly supplied in the first half of use, and high boiling point components are mainly supplied in the latter part of use, so the balance of each component supplied to the user is different at each timing of use. For this reason, in non-combustible heated flavor absorption articles, it is required to maintain a uniform balance of each component supplied to the user from the first half of use to the second half of use.

The purpose of the present invention is to provide a non-combustible heated flavor suction article and a non-combustible heated flavor suction system in which the balance of each component supplied to the user is uniform from the first half of use to the second half of use.

[Non-combustible heated flavor absorption article]

A non-combustible heated flavor inhalation article according to the present embodiment includes an aerosol generating rod and a mouthpiece segment. The aerosol-generating rod includes a first segment comprising an aerosol-generating substrate and a second segment comprising a flavor ingredient. Additionally, the mouthpiece segment includes a cooling segment and a filter segment.

In the non-combustible heated flavor absorption article according to the present embodiment, the aerosol generating rod includes a first segment containing an aerosol generating substrate and a second segment containing a flavor component such as a tobacco component. For this reason, when heating the aerosol generating rod, the heating temperature of the first segment containing the aerosol generating base material with a high boiling point (low vapor pressure) is raised, and the flavor component containing the low boiling point (high vapor pressure) flavor component is raised. The heating temperature of the second segment can be lowered. As a result, volatilization of flavor components with low boiling points (high vapor pressure) can be suppressed throughout use, and volatilization and supply of flavor components can be maintained until the latter half of use. Additionally, it can promote volatilization of aerosol-generating substrates with high boiling points (low vapor pressure) throughout use. Therefore, in the non-combustible heated flavor absorption article according to the present embodiment, the balance of each component supplied to the user from the first half to the second half of use can be made uniform.

An example of a non-combustible heated flavor suction article according to the present embodiment is shown in Fig. 1(a). The non-combustible heated flavor inhalation article 1 shown in FIG. 1(a) includes an aerosol generating rod 2 and a mouthpiece segment 3. The aerosol-generating rod 2 has a first segment 4 containing an aerosol-generating substrate, and a second segment 5 containing a flavor component, which is disposed downstream from the first segment 4. The mouthpiece segment 3 includes a cooling segment 6, a center hole segment 7, and a filter segment 8 in this order from the upstream side. Additionally, in this embodiment, the mouthpiece segment 3 does not need to be provided with the center hole segment 7. In use, at least a portion of the aerosol-generating rod 2 (mainly the first segment 4) is heated, the aerosol-generating substrate of the first segment 4 and the flavor component of the second segment 5 are vaporized and inhaled. They are thereby transferred to the mouthpiece segment (3) and suction takes place at the end of the filter segment (8).

(Aerosol Generating Load)

The aerosol-generating rod according to this embodiment includes a first segment containing an aerosol-generating substrate and a second segment containing a flavor component. The aerosol generating rod according to the present embodiment may include a plurality of the first segments and/or the second segments.

<First segment>

The first segment related to this embodiment includes an aerosol-generating substrate. Examples of aerosol-generating substrates include glycerin, propylene glycol, and 1,3-butanediol. These may be used one type or two or more types may be used together.

The first segment preferably further contains plant fibers from the viewpoint of sufficiently retaining the aerosol-generating substrate. Examples of plant fibers include wood pulp, hemp, corn, bamboo, cotton, and tobacco. These may be used one type or two or more types may be used together. The plant fiber may be a plant fiber sheet made up of plant fibers. From the viewpoint of ensuring that the aerosol-generating base material is stably held by the plant fiber sheet and ensuring the required amount of aerosol production, the plant fiber preferably contains 10 to 50% by mass of the aerosol-generating base material, and preferably contains 12 to 30% by mass. It is more desirable to do so.

The first segment includes a cylindrical wrapper and a non-woven fabric composed of plant fibers filled inside the wrapper, and the non-woven fabric preferably includes an aerosol-generating substrate. In the first segment, the aerosol-generating substrate can be sufficiently held by the non-woven fabric. The thickness of the nonwoven fabric is not particularly limited, but may be, for example, 1 to 2 mm. The nonwoven fabric preferably contains 10 to 50% by mass of an aerosol-generating base material, and more preferably contains 12 to 30% by mass.

Additionally, the first segment preferably includes a cylindrical wrapper and paper composed of plant fibers filled inside the wrapper, and the paper includes an aerosol-generating substrate. In the first segment, the aerosol-generating substrate can be sufficiently held by the paper. The thickness of the paper is not particularly limited, but may be, for example, 50 to 200 μm. The paper preferably contains 10 to 50% by mass of an aerosol-generating substrate, and more preferably contains 12 to 30% by mass.

In the first segment, as shown in FIG. 2(a), for example, it is preferable that several sheet-shaped nonwoven fabrics 21 are stacked and folded into an S-shape to fill the inside of the wrapper. Since the non-woven fabric is folded and filled in this first segment, the gap between the non-woven fabrics is not normally visible, but when an internal heating heater such as a blade shape or a rod shape is inserted, the heater enters the gap between the non-woven fabrics. , there is no damage to the nonwoven fabric itself. For this reason, when the heater is heated, it is possible to prevent the nonwoven fabric from burning and breaking easily and remaining as waste in the device.

In addition, in the first segment, as shown in Fig. 2(b), for example, it is preferable that the inside of the wrapper is filled with sheet-shaped paper 31 in a gathered state. In this first segment, when a heater for internal heating, such as a blade shape or a rod shape, is inserted into the first segment, the heater enters the gap between the papers and the paper itself is not damaged. For this reason, when the heater is heated, paper etc. becomes easily burned and broken, and it can be prevented from remaining as waste in the device. Additionally, the nonwoven fabric may also be filled with gathered filling rather than folded into the S-shaped shape. When the gathers are filled, a plurality of channels through which air easily permeates are formed in the air flow direction, so the ventilation resistance of the first segment can be lowered.

Additionally, from the viewpoint of suppressing oozing of the aerosol-generating substrate, it is preferable to use a wrapper with low liquid permeability. Wrappers that are difficult for liquid to permeate include, for example, metal foil, a sheet of metal foil and paper, polymer film, a sheet of polymer film and paper, and liquids such as modified cellulose, modified starch, polyvinyl alcohol, and vinyl acetate on the surface. Examples include paper coated with a coating agent that can prevent the penetration of . In addition to preventing liquid penetration, it is preferable that the wrapper contains a metal foil with excellent thermal conductivity from the viewpoint of uniformizing the temperature distribution in the longitudinal direction of the first segment. In addition, by placing metal foil on the inside and paper on the outside after loading the sheet as a sheet of metal foil and paper, the appearance can be made similar to a normal combustible flavor inhalation article (cigarette). When the amount of aerosol-generating substrate included in the first segment is relatively small, paper is applied to the surface with a coating agent that can prevent the penetration of liquids such as modified cellulose, modified starch, polyvinyl alcohol, and vinyl acetate. The use is preferable because the rod hardness, elasticity, and feel of the first segment can be made similar to those of a typical combustible flavored inhalation article (cigarette).

When the wrapper is a laminate of a paper layer constituting the outer surface and a liquid impermeable layer constituting the inner surface, the liquid impermeable layer is metal foil, polymer film, modified cellulose, modified starch, or polyvinyl. It may be composed of a coating layer selected from the group consisting of alcohol and vinyl acetate. Here, it is preferable that the wrapper is formed into a cylindrical shape by adhering the liquid impermeable layers of the wrapper to one end and the other end of the wrapper. For example, as shown in FIG. 3, the nonwoven fabric 22 containing an aerosol-generating substrate is a laminate of a paper layer 24 constituting the outer surface and a liquid impermeable layer 23 constituting the inner surface. It is filled within a shaped wrapper. Here, the liquid-impermeable layers 23 are bonded to each other at one end and the other end of the wrapper (adhesive portion 25), so that the wrapper is formed into a cylindrical shape. By adhering the liquid impermeable layers to each other in this way, it is possible to further suppress the aerosol-generating base material from seeping to the outside.

The first segment preferably further contains a thickener from the viewpoint of improving the retention of the aerosol-generating substrate. For example, aerosol-generating base materials such as glycerin and propylene glycol are liquid at room temperature, and when included in large amounts in nonwoven fabrics, etc., there is a possibility that they may flow out of the nonwoven fabric. However, by further including a thickener in the non-woven fabric, etc., outflow of the aerosol-generating substrate to the outside can be suppressed and handling is improved. Examples of thickeners include thickening polysaccharides such as gellan gum, tamarind gum, agar, carrageenin, pectin, and alginate, proteins such as collagen and gelatin, and modified cellulose such as HPC, CMC, and HPMC. These thickeners may be used one type or two or more types may be used together. When the first segment contains a thickener, the content of the thickener depends on the type of thickener used, but is preferably 0.1 to 5.0 parts by mass per 100 parts by mass of the aerosol-generating base material. For example, when using glycerin as an aerosol generating base, native gellan gum as a thickener, and water as a diluent, 0.3 to 0.7 parts by mass of native gellan gum and 23.5 parts by mass of water are used per 100 parts by mass of glycerin. By making it a mass part, it is possible to obtain an aerosol-generating base material having a viscosity of 2000 to 26000 (mPa·s at 25°C) and excellent viscosity. The aerosol-generating base material is in a gel state in the room temperature range, and becomes liquid when heated to about 60 to 70 degrees Celsius. In this way, when manufacturing the first segment, the aerosol-generating base material can be easily incorporated by heating it and applying it to a non-woven fabric or paper in a liquid state. After the temperature is lowered to room temperature, it enters a gel state and is stably held.

In addition to the aerosol-generating base material, plant fiber (non-woven fabric or paper), wrapper, and thickener, the first segment may also include, for example, a tobacco component, a flavoring component other than a tobacco component (external flavoring agent), etc. Examples of flavor components other than tobacco components include L-menthol, licorice extract, reducing sugar, and cocoa extract. Additionally, the first segment may not include flavor ingredients.

The axial length of the first segment is not particularly limited, but may be, for example, 5 to 15 mm. Additionally, the circumferential length of the first segment is not particularly limited, but may be, for example, 15 to 24 mm.

<Second segment>

The second segment according to this embodiment contains a flavor component. Examples of flavor components include tobacco components such as dried tobacco plants, tobacco extracts, concentrated or fractionated tobacco extracts, and flavor components other than the tobacco components. When the second segment includes tobacco components, the second segment may include one or more types of tobacco material selected from the mesophyll, veins, stems, flowers, and roots of the tobacco plant. Additionally, the tobacco material may be a tobacco sheet described later. The second segment may include, for example, a tubular wrapper and the tobacco material filled inside the wrapper.

The tobacco material may include a flavor development agent. The flavor development aid may include at least one of carbonate, bicarbonate, oxide, and hydroxide of an alkali metal and/or alkaline earth metal. Preferably, the flavor development aid is potassium carbonate or sodium carbonate. Since most of the tobacco components contained in the tobacco material are amines, when the tobacco material contains a flavor expression auxiliary, volatilization of the tobacco components is ensured even at a relatively low temperature, and the tobacco flavor can be sufficiently expressed. The amount of the flavor expression aid contained in the tobacco material is preferably 5 to 20 parts by mass with respect to 100 parts by mass of the tobacco material. By adding a flavor development aid, the pH of the tobacco material may be 7 to 11. Additionally, pH can be measured with a pH meter (for example, IQ240 manufactured by IQ Scientific Instruments Inc.). For example, 10 times the mass ratio of distilled water is added to 2 to 10 g of tobacco material, and the mixture of water and tobacco material is shaken at 200 rpm for 10 minutes at room temperature (e.g., 22°C). ) and after standing for 5 minutes, measure the pH of the obtained extract with a pH meter.

Additionally, the tobacco material may contain lipids. Examples of lipids include acylglycerols such as monoglyceride, diglyceride, and triglyceride, and fatty acids. These may be used one type or two or more types may be used together. When the tobacco material contains lipids, excessive volatilization of flavor components such as nicotine can be suppressed due to the interaction between the lipids and the flavor components such as nicotine contained in the tobacco material. Additionally, because tobacco materials contain lipids, lipids may also be included in the aerosol generated during use, albeit in trace amounts. By doing this, it is possible to suppress re-vaporization of the flavor component after the vapor of the flavor component or the aerosol-generating substrate is cooled and an aerosol is formed. The amount of lipid contained in the tobacco material is preferably 2 to 15 parts by mass with respect to 100 parts by mass of the tobacco material.

The second segment is, for example, a cylindrical wrapper in which strands of tobacco leaves are randomly filled, and the angles of the tobacco sheets are randomly filled. It may be filled with or aligned, or filled by gathering the cigarette sheets without recreating them, etc. Hereinafter, the angle where the tobacco leaf is re-engraved and the angle of the tobacco sheet are collectively referred to as the tobacco angle. Examples of the wrapper include wrapping paper in the shape of a cylinder. The content of nicotine in the filling filled in the wrapper is preferably 1.5% by mass or more, and more preferably 2.0 to 4.0% by mass. In addition, the packing density of the tobacco pieces filled in the wrapper is preferably set to 0.2 to 0.7 mg/mm3 because sufficient flavor components are produced during use and sufficient rod hardness of the second segment is ensured. .

There are no special restrictions on the size or preparation method of the tobacco packet. As an example, aged tobacco leaves are chopped into pieces of 0.5 mm or more and 2.0 mm or less in width and 3 mm or more and 10 mm or less in length. A tobacco shell of this size is desirable for filling with a filling object. As another example, processed tobacco leaves are chopped into pieces (strand-type pieces) so that the width is 0.5 mm or more and 2.0 mm or less, and the length is longer than the above-mentioned tobacco pieces, and preferably the same length as the stuff to be filled. I can hear it. For the strand type angle, it is preferable to use a tobacco sheet from the viewpoint of ease of molding.

The moisture content of the tobacco shell may be 10 mass% or more and 15 mass% or less, and is preferably 11 mass% or more and 13 mass% or less, based on the total mass of the tobacco shell. With such a moisture content, the occurrence of coiling after the tobacco shell is filled with the filling material can be suppressed.

A tobacco sheet can be obtained by molding a composition containing aged tobacco leaves, etc. into a sheet shape. The aged tobacco leaves used for tobacco sheets are not particularly limited, but examples include those that have been deboned and separated into lamina and midbone. In addition, in this specification, “sheet” refers to a shape having a pair of substantially parallel main surfaces and side surfaces.

Cigarette sheets can be molded by known methods such as papermaking, casting, rolling, etc. Details regarding various tobacco sheets molded by this method are disclosed in "Dictionary of Tobacco, Tobacco Research Center, March 31, 2009."

Examples of a method of forming a tobacco sheet by a papermaking method include a method including the following steps.

(1) A process of extracting water-soluble components from aged tobacco leaves by crushing them and mixing and stirring them with a solvent such as water.

(2) A process of separating water extract and residue as water-soluble components.

(3) A process of concentrating the water extract by drying it under reduced pressure.

(4) A process of adding pulp to the residue and converting it into fiber using a refiner to obtain a mixture (homogenization process).

(5) A process of papermaking a mixture of fiberized residue and pulp.

(6) A process of adding concentrated water extract to the papermaking sheet and drying it to make a tobacco sheet.

When molding a tobacco sheet by this method, a step to remove some components such as nitrosoamine may be added (see Japanese Patent Application Publication No. 2004-510422). The tobacco sheet provided in the non-combustible heated flavor inhalation article may contain an aerosol-generating substrate. When producing a tobacco sheet by a papermaking method, the concentrate of the water extract and the aerosol-generating base material may be mixed and added in step (6) above, or the aerosol-generating base material may be added after step (6) above. .

Examples of a method of forming a tobacco sheet by the slurry method include a method including the following steps.

(1) A process of obtaining a mixture by mixing water, pulp, binder, and pulverized aged tobacco (homogenization process).

(2) A process of stretching (casting) the mixture thinly and drying it to make a tobacco sheet.

When forming a tobacco sheet using this method, a process of removing some components such as nitrosoamine can be added by irradiating ultraviolet rays or do. The tobacco sheet provided in the non-combustible heated flavor inhalation article may contain an aerosol-generating substrate. When producing a tobacco sheet by the slurry method, the aerosol-generating base material may be mixed into the mixture of (1) above, or the aerosol-generating base material may be spray-added to the dried sheet following step (2).

Examples of a method of forming a tobacco sheet by the rolling method include a method including the following steps.

(1) A process of obtaining a mixture by mixing water, pulp, binder, and pulverized aged tobacco (homogenization process).

(2) A process of rolling the mixture by putting it into a plurality of rolling rollers.

(3) A process of peeling the rolled product on the rolling roller with a doctor knife, transferring it to a net conveyor, and drying it in a dryer.

When forming a tobacco sheet by this method, depending on the purpose, the surface of each rolling roller may be heated or cooled, and the rotation speed of each rolling roller may be adjusted. Additionally, by adjusting the spacing between each rolling roller, a tobacco sheet of desired basis weight can be obtained. The tobacco sheet provided in the non-combustible heated flavor inhalation article may contain an aerosol-generating substrate. When manufacturing a tobacco sheet by the rolling method, an aerosol-generating base material may be mixed with the mixture of (1) above, or the aerosol-generating base material may be spray-added to the dried sheet following step (3).

In addition to the above molding method, a nonwoven tobacco sheet can be molded according to a method including the following steps described in International Publication No. 2014/104078.

(1) A process of obtaining a mixture by mixing aged tobacco grinds and a binder (homogenization process).

(2) A process of sandwiching the mixture with a non-woven fabric.

(3) A process of forming the laminate into a certain shape by heat welding to obtain a non-woven tobacco sheet.

When incorporating an aerosol-generating base material into a non-woven tobacco sheet, (3) the aerosol-generating base material may be spray-applied next.

In the homogenization process of the substrate by each of the above methods, from the viewpoint of obtaining a tobacco sheet with a certain strength, the average fiber length of the tobacco fibers contained in each mixture is 200 ㎛ or more and 1000 ㎛ or less, and the freeness of each mixture is It is preferable that the water resistance is 20°SR or more and 50°SR or less. The average fiber length of tobacco fibers is measured by automatic optical analysis (JIS P8226-2) using non-polarized light with a fiber count of 20,000 or more. Freeness is measured by the Schoffer-Rigra method (JIS P8121).

The length and width of the tobacco sheet are not particularly limited and can be adjusted appropriately according to the mode of filling with the filling material described later. The thickness of the tobacco sheet is not particularly limited, but is preferably 150 μm or more and 1000 μm or less, and more preferably 200 μm or more and 600 μm or less in terms of balance between heat transfer efficiency and strength.

The composition of the tobacco sheet is not particularly limited, but for example, the content of aged tobacco leaves is preferably 50% by mass or more and 95% by mass or less with respect to the total mass of the tobacco sheet. Additionally, the tobacco sheet may contain a binder, and examples of related binders include guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), etc. there is. The content of the binder is preferably 1% by mass or more and 20% by mass or less with respect to the total mass of the tobacco sheet. Tobacco sheets may also contain other additives. Examples of other additives include fillers such as pulp. The content of the filler is not particularly limited, but is preferably 1% by mass or more and 20% by mass or less with respect to the total mass of the tobacco sheet. Here, the water extraction residue of aged tobacco, which is an intermediate product when forming a tobacco sheet by the papermaking method, is different from the filler.

The filling density of the tobacco material inside the wrapper can be appropriately set depending on the form of the tobacco material being filled, the intended flavor, ventilation resistance, etc. For example, the packing density may be 0.2 mg/mm3 or more and 0.7 mg/mm3 or less. The fill density is calculated by the ratio of the mass of the tobacco material to the volume within the rod formed by the wrapper.

The axial length of the second segment is not particularly limited, but may be, for example, 5 to 15 mm. Additionally, the circumferential length of the second segment is not particularly limited, but may be, for example, 15 to 24 mm.

<Configuration of aerosol generating rod>

The configuration of the aerosol generating rod is not particularly limited as long as the aerosol generating rod includes the first segment and the second segment, but the second segment is located on the mouthpiece segment side (downstream side) with respect to the first segment. It is desirable that it is placed. For example, as shown in FIG. 1(a), the column-shaped second segment 5 may be disposed on the mouthpiece segment 3 side (downstream side) with respect to the column-shaped first segment 4. In Figure 1(a), the first segment 4 may be constructed by filling the first wrapper 10 with a non-woven fabric 9 comprised of plant fibers and including an aerosol-generating substrate. Additionally, the second segment 5 may be constructed by filling the second wrapper 12 with tobacco material 11 . The ease of volatilization of each component contained in the first segment and the second segment is mainly determined by the heating temperature, but the presence of a substance highly compatible with the component to volatilize in the surroundings promotes volatilization of the component. In the above configuration, the aerosol-generating base material volatilized in the first segment is cooled and liquefied (aerosolized) at the moment it flows into the second segment during suction, and the flavor component (e.g. nicotine) present in the second segment is absorbed. By dissolving in the aerosol and taking it out of the aerosol generating rod, the concentration of the flavor component in the second segment is lowered and volatilization is promoted. By this, release efficiency is ensured even without raising the temperature of the second segment that much. For this reason, the flavor component can be released from the second segment for each puff operation at a low temperature, and as a result, it is possible to suppress the flavor component from being completely consumed. The ratio (A/B) of the length (A) of the first segment to the length (B) of the second segment in the axial direction of the aerosol generating rod is preferably 0.3 to 3.0, and more preferably 0.5 to 2.0. do.

The first segment and the second segment may be connected as recommended by an outer wrapper. Here, the outer wrapper may be a normal paper wrapper, but is preferably an outer wrapper containing a heat-conducting material. By encouraging the first segment and the second segment with an outer wrapper containing a heat-conducting material, for example, even when only the side of the first segment is heated by the outer heating heater, the heat from the heater is uniformly distributed to the second segment. and can be carried out efficiently. Examples of the heat conductive material include metal foil, which has a higher heat conductivity than paper. In particular, as represented by aluminum foil and stainless steel foil, the thermal conductivity is 10 W/m·K or more, it is inexpensive, resistant to rust, and has high processing characteristics (thickness of several ㎛ to 10 ㎛, high tensile strength, and easy to bend). ) It is preferable to use metal foil. For reference, Table 1 shows the thermal conductivity of representative metal foils (alloy foils).

Additionally, the column-shaped first segment may be installed extending in the axial direction of the aerosol generating rod, and the second segment may be disposed on the outer periphery of the first segment. For example, as shown in FIG. 4(a), the second segment 5 may be disposed on the outer periphery (on the side) of the column-shaped first segment 4. In this configuration, heating can be achieved by inserting an internal heater such as a blade heater into the first segment. In the above configuration, since the first segment to be heated to a higher temperature is formed in a three-window shape, it is preferable in that the first segment can be efficiently heated to a high temperature with an internal heater. In addition, the ease of flow of air in the longitudinal direction of the columnar rod during suction is set to make the second segment easier to flow compared to the first segment by adjusting the filling density of each filler, so that the aerosol generating base is mainly generated from the first segment. Rather than moving directly in the direction of the mouthpiece, the aerosol-generating substrate mainly generated from the first segment may move to the second segment, taking the flavor component with it and then moving to the mouthpiece portion. In this case, the interface between the first segment and the second segment is preferably made of a permeable wrapper through which gases or aerosols can pass, for example, paper with an air permeability of 1000 to 30000 Coresta units. In addition, even if there is no wrapper or the like at the interface, it is preferable from the viewpoint of promoting the movement of gas components from the first segment to the second segment.

Additionally, the column-shaped second segment may be installed extending in the axial direction of the aerosol generating rod, and the first segment may be disposed on the outer periphery of the second segment. For example, as shown in FIG. 4(b), the first segment 4 may be disposed on the outer periphery (on the side) of the column-shaped second segment 5. In this configuration, the side surface of the first segment can be heated with a peripheral heating heater. The above configuration is preferable in that the first segment to be heated to a higher temperature is efficiently heated to a higher temperature by the external heater. In addition, the ease of flow of air in the longitudinal direction of the columnar rod during suction is set to make the second segment easier to flow compared to the first segment by adjusting the filling density of each filler, so that the aerosol generating base is mainly generated from the first segment. Rather than moving directly in the direction of the mouthpiece, the aerosol-generating substrate mainly generated from the first segment may move to the second segment, taking the flavor component with it and then moving to the mouthpiece portion. In this case, the interface between the first segment and the second segment is preferably made of a permeable wrapper through which gases or aerosols can pass, for example, paper with an air permeability of 1000 to 30000 Coresta units. In addition, even if there is no wrapper or the like at the interface, it is preferable from the viewpoint of promoting the movement of gas components from the first segment to the second segment.

The axial length of the aerosol generating rod is not particularly limited, but may be, for example, 12 to 50 mm. Additionally, the circumferential length of the aerosol generating rod is not particularly limited, but may be, for example, 15 to 24 mm.

(Mouthpiece Segment)

The mouthpiece segment according to this embodiment includes a cooling segment and a filter segment. The mouthpiece segment according to this embodiment may include a plurality of cooling segments and/or filter segments. Additionally, the mouthpiece segment according to the present embodiment may include segments other than the cooling segment and the filter segment. Other segments include, for example, center hole segments.

<Cooling segment>

As shown in FIG. 1(a), the cooling segment 6 may be comprised of a cylindrical member 13. The cylindrical member 13 may be, for example, a paper pipe obtained by processing cardboard into a cylindrical shape.

The cooling segment is located downstream of the aerosol generating rod. The function required for the cooling segment is to cool the vapor of the flavor component or aerosol-generating substrate generated by the aerosol-generating rod during use while minimizing the reduction of the vapor of the flavor component or aerosol-generating substrate by filtration or adsorption. It is liquefied (aerosolized). For example, during suction, the difference between the segment internal temperature at the cooling segment inlet and the segment internal temperature at the cooling segment outlet may be 20°C or more. When a flavor component or a high-temperature vapor component of an aerosol-generating substrate passes through a segment filled with cellulose acetate fibers, which is used as a filter member for a typical combustion-type flavor-absorbing article, the temperature difference between the segment inlet and the segment outlet is 20°C or more. However, when the vapor of flavor components or aerosol-generating substances passes through the fiber-filled layer, a large amount is reduced by filtration or adsorption. This fiber-filled layer is not referred to herein as a cooling segment.

One aspect of the cooling segment may be a hollow tube made by processing a single sheet of paper or several sheets of paper glued together into a cylindrical shape. In addition to the above-described paper, the material constituting the pipe may be a cellulose acetate fiber corrugated into a sheet shape, or a plastic film such as polyolefin or polyester. Additionally, in order to increase the cooling effect by bringing room temperature outside air into contact with high temperature steam, it is preferable that there be a hole for introducing outside air around the pipe. By applying a polymer coating, such as polyvinyl alcohol, or a polysaccharide coating, such as pectin, to the inner surface of the tube, the cooling effect can be increased by utilizing the heat of dissolution accompanying the endotherm of the coating or phase change. The ventilation resistance of this tubular cooling segment is 0 mmH ₂ O.

As another aspect of the cooling segment, it is also preferable to fill the inside of a cylindrical pipe with a cooling sheet member. In this case, by providing one or more air distribution channels in the flow direction, it is possible to achieve component removal when passing through a low-level segment while cooling with a cooling sheet. It is preferable that the ventilation resistance of the cooling segment when this cooling sheet is filled is 0 to 30 mmH ₂ O. Breathing resistance (RTD) is the pressure required to push air through the full length of an object under a test flow of 17.5 ml/sec at 22°C and 101 kPa (760 torr). RTD is generally expressed in units of mmH ₂ O and is measured according to ISO 6565:2011. Also in this mode in which the cooling sheet is filled, a hole for introducing outside air may be provided in the pipe member.

The total surface area of the cooling sheet member is 300 mm 2 /mm or more and 1000 mm 2 /mm or less. This surface area is the surface area per length (mm) in the ventilation direction of the cooling sheet member. The total surface area of the cooling sheet member is preferably 400 mm2/mm or more, more preferably 450 mm2/mm or more, while it is preferably 600 mm2/mm or less, and more preferably 550 mm2/mm or less.

From the viewpoint of cooling function, it is desirable for the cooling sheet member to have a large surface area. From the viewpoint of reducing the removal of flavor components or aerosol-generating substrates by filtration or adsorption, it is preferable that the ventilation resistance of the cooling segment filled with the cooling sheet member is low. Accordingly, in a preferred embodiment, the cooling sheet may be formed by sheets of thin material that are pleated, then gathered, and folded to form channels in the flow direction.

In some embodiments, the thickness of the cooling sheet member constituent material is 5 μm or more and 500 μm or less, for example, 10 μm or more and 250 μm or less.

The material of the cooling sheet member may be a sheet material such as metal foil, polymer sheet, or paper with low breathability. In one embodiment, the cooling segment may include a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil.

Additionally, it is preferable to use paper as a material for the cooling sheet member from the viewpoint of reducing environmental load. The paper used for the cooling sheet member preferably has a basis weight of 30 to 100 g/m2 and a thickness of 20 to 100 μm. From the viewpoint of reducing the removal of flavor components and aerosol-generating base components in the cooling segment, the paper as the cooling sheet material preferably has a low air permeability, and the air permeability is preferably 10 Coresta units or less. By coating paper as a cooling sheet member with a polymer coating such as polyvinyl alcohol or a polysaccharide such as pectin, the cooling effect can be increased by utilizing the heat of dissolution accompanying the endotherm of the coating or phase change.

In Fig. 1(a), a perforation 14 penetrating the cylindrical member 13 and the mouthpiece lining paper 20, which will be described later, is provided. Due to the presence of perforations 14 , outside air is introduced into the cooling segment 6 during suction. As a result, the aerosol vaporization component generated by heating the aerosol generating rod 2 comes into contact with the outside air and is liquefied due to a decrease in temperature, thereby forming an aerosol. The diameter (diameter length) of the perforation 14 is not particularly limited, but may be, for example, 0.5 mm or more and 1.5 mm or less. The number of perforations 14 is not particularly limited and may be one or two or more. For example, a plurality of perforations 14 may be provided around the cooling segment 6.

The amount of outside air introduced from the perforation 14 is preferably 85 volume% or less, and more preferably 80 volume% or less, relative to the total volume of gas sucked by the user. When the ratio of the amount of outside air is 85 volume% or less, reduction in flavor due to dilution by outside air can be sufficiently suppressed. Additionally, this is also called ventilation ratio. From the viewpoint of cooling properties, the lower limit of the ventilation ratio range is preferably 55 volume% or more, and more preferably 60 volume% or more.

In some embodiments, the temperature of the generated aerosol may drop by more than 10°C when it is drawn into the user through the cooling segment. In another embodiment, the temperature may decrease by 15°C or more, and in another embodiment, the temperature may decrease by 20°C or more.

The cooling segment can be formed into a rod shape whose axial length is, for example, 7 mm or more and 30 mm or less. For example, the axial length of the cooling segment may be 20 mm.

In some embodiments, the cooling segment is substantially circular in its axial cross-sectional shape, and has a circumferential length of preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. desirable.

<Center hole segment>

The center hole segment is composed of a filled layer having one or more hollow portions and an inner plug wrapper (inner wrapper) that covers the filled layer. For example, as shown in Figure 1 (a), the center hole segment 7 includes a second filling layer 15 having a hollow portion and a second inner plug wrapper covering the second filling layer 15 ( 16). The center hole segment 7 has the function of increasing the strength of the mouthpiece segment 3. The second filled layer 15 is, for example, filled with cellulose acetate fibers at high density, and a plasticizer containing triacetin is added in an amount of 6% by mass or more and 20% by mass or less relative to the mass of cellulose acetate, and hardened to have an inner diameter of ϕ1.0. It can be said to be a rod of ㎜ or more and ϕ5.0 mm or less. Since the second packed layer 15 has a high packing density of fibers, during suction, air or aerosol flows only through the hollow portion and hardly flows inside the second packed layer 15. Since the second filled layer 15 inside the center hole segment 7 is a fiber-filled layer, the tactile sensation from the outside during use is less likely to cause discomfort to the user. Additionally, the center hole segment 7 may not have the second inner plug wrapper 16 and its shape may be maintained by thermoforming.

<filter segment>

The structure of the filter segment is not particularly limited, but may be composed of a single or plural filled layer. For example, as shown in Fig. 1(a), in the filter segment 8, the outside of the first filling layer 17 may be covered with a first inner plug wrapper 18 (inner wrapper). The ventilation resistance per segment of the filter segment can be appropriately changed depending on the amount of filler and material filled in the filter segment. For example, when the filling is cellulose acetate fiber, increasing the amount of cellulose acetate fiber filled in the filter segment can increase ventilation resistance. When the filling is cellulose acetate fiber, the packing density of the cellulose acetate fiber may be 0.13 to 0.18 g/cm3. Also, even at the same packing density, it is preferable that the thickness of the cellulose acetate fibers being filled is thicker in order to develop lower ventilation resistance. The thickness of one cellulose acetate fiber is preferably 5 to 20 denier/filament. Additionally, from the viewpoint of high-speed manufacturing of filter segments, it is more preferable that the denier is 7 to 13 denier/filament. In addition, ventilation resistance is a value measured by a ventilation resistance meter (brand name: SODIMAX, manufactured by SODIM).

The circumferential length of the filter segment is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The axial length of the filter segment can be selected from 5 to 20 mm, and is selected so that its ventilation resistance is 10 to 60 mmH ₂ O/seg. The axial length of the filter segment is preferably 5 to 9 mm, and more preferably 6 to 8 mm. The cross-sectional shape of the filter segment is not particularly limited, but may be, for example, circular, oval, or polygonal. Additionally, destructible capsules containing fragrance, fragrance beads, or fragrance may be added directly to the filter segment.

As shown in Fig. 1(a), the center hole segment 7 and the filter segment 8 can be connected with an outer plug wrapper (outer wrapper) 19. The outer plug wrapper 19 may be, for example, a cylindrical piece of paper. Additionally, the aerosol generating rod 2, the cooling segment 6, and the connected center hole segment 7 and filter segment 8 can be connected by the mouthpiece lining paper 20. This connection can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 20 and wrapping the three segments. Additionally, these segments may be divided and connected several times with a plurality of lining papers. Additionally, as shown in FIG. 1(b), the first segment 4 may be fixed by the mouthpiece lining paper 20. In addition, as shown in Figure 1 (c), after connecting the first segment 4 and the second segment 5 by the outer wrapper 34, an aerosol generating rod ( 2) may be connected to the cooling segment 6 and the connected center hole segment 7 and filter segment 8.

It is more preferable that it is 60 mm or less. In addition, the circumferential length of the non-combustible heated flavor suction article is preferably 16 mm or more and 25 mm or less, more preferably 20 mm or more and 24 mm or less, and even more preferably 21 mm or more and 23 mm or less. For example, the length of the aerosol generating rod is 20 mm, the length of the cooling segment is 20 mm, the length of the center hole segment is 8 mm, and the length of the filter segment is 7 mm. Additionally, the length of the filter segment can be selected within the range of 4 mm or more and 20 mm or less. Additionally, the ventilation resistance of the filter segment at that time is selected to be 10 mmH ₂ O/seg or more and 60 mmH ₂ O/seg or less per segment. The length of these individual segments can be appropriately changed depending on manufacturing suitability, required quality, etc. Additionally, even if only the filter segment is disposed on the downstream side of the cooling segment without using the center hole segment, it can function as a non-combustible heated flavor suction article.
