Description

Technical Field

[0001] The present invention relates to a member for a flavor inhalation article, a flavor inhalation article, a phenol capturing agent for the flavor inhalation article, and a method for producing the member for the flavor inhalation article. Background Art

[0002] The filter tips of flavored smoking articles such as cigarettes and non-combustion tobacco are required to reduce undesirable components in mainstream smoke while maintaining the flavor. As one of the methods for achieving this, it is known that a substance with selective filtering ability for a specific component is loaded on the filter tip in the form of an additive. When the additive leaks out of the filter tip, the selective filtering ability of the filter tip for a specific component is reduced. Therefore, such a filter tip requires storage stability, which refers to the property that the above-mentioned additive in an amount sufficient to maintain its selective filtering ability is retained in the filter tip until the user inhales.

[0003] As a component to be filtered from mainstream smoke that is generated when the flavored smoking article is burned or heated, phenol, which is known to be a stimulant, can be cited. By selectively filtering phenol, the flavor can be improved. Summary of the invention

[0032] Hereinafter, the present invention will be described in detail. However, the following description is for explaining the present invention in detail and is not intended to limit the present invention.

[0033] The phenol capturing agent of the embodiment is a phenol capturing agent for a flavor inhalation article, comprising a substance satisfying the following formulas (1) to (3).

[0034] HSP(phenol)≤8···(1)

[0035] Vp≤0.2Pa···(2)

[0036] DP ≥ 50℃···(3)

[0037] Wherein, HSP(phenol) is the distance between the Hansen solubility parameter of the above substance and the Hansen solubility parameter of phenol, Vp is the vapor pressure of the above substance, and DP is the dropping point of the above substance.

[0038] <1. Members for scent inhalation articles>

[0039] The inventors of the present invention have found in the exploration of a component for a flavor inhalation article having a selective filtering ability for phenol and excellent storage stability that the desired effect can be obtained by loading monoolein as an additive (phenol capture agent) on a component for a flavor inhalation article of a base component. Moreover, various parameters have been measured for monoolein. Below, the measured parameters are described. It should be noted that the base component will be described later, and the base component can be one of the components constituting smoking articles such as cigarettes, the components constituting non-combustion heating type flavor inhalation articles, and the components constituting non-combustion non-heating type flavor inhalation articles.

[0040] Among specific parameters related to a certain substance, the Hansen Solubility Parameters HSP (HSP: Hansen Solubility Parameters) can be cited as a parameter that affects the phenol selective filtration ability.

[0041] The Hansen solubility parameter is obtained by decomposing the solubility parameter δt (SP: Solubility Parameter) introduced by Hildebrand into the intermolecular dispersion force contribution term δ d , the intermolecular dipole-dipole interaction contribution δ p , and the intermolecular hydrogen bond contribution δ h , thus expanding the applicable substances to polar substances and substances that produce hydrogen bonds. In the specification and claims of this application, when the "Hansen solubility parameter" is recorded, it refers to the Hansen solubility parameter at 25°C when no temperature is recorded. t The relationship with the three contribution terms is shown in the following formula.

[0042] [Mathematical formula 1]

[0043]

[0044] Dispersion force contribution δ d , the dipole-dipole interaction contribution δ p and hydrogen bond contribution δ h These three parameters can be viewed as coordinates in a three-dimensional space with each parameter as the axis. At a specific temperature, various substances have inherent HSPs, such as Figure 1 As shown in FIG. 1 , the HSPs of these substances appear as points at different positions in the three-dimensional space. It can be considered that the distance R between two points is represented by the following formula: ij The smaller it is, the higher the solubility (compatibility) of a certain substance i with other substances j.

[0045] [Mathematical formula 2]

[0046]

[0047] Therefore, the effect of a substance X on the phenol selective filtration capability can be evaluated by calculating the distance between the position of the HSP of phenol in the above three-dimensional space and the position of the HSP of the substance X. In the present specification and claims, the distance R between the Hansen solubility parameter of phenol and the Hansen solubility parameter of a substance X obtained by the above equation is ij Defined as HSP (phenol).

[0048] The HSP (phenol) of monoolein is 7.14. It can be judged that substances with an HSP (phenol) of 8 or less can achieve practical phenol selective filtering capabilities. This is based on the confirmation that the HSP (phenol) of propylene glycol, which can achieve high phenol selective filtering capabilities, is 8. A component for a flavor inhalation article in one embodiment includes a phenol capture agent containing a substance with an HSP (phenol) of 8 or less. The smaller the HSP (phenol) value of the substance contained in the phenol capture agent, the better, for example, it is greater than 0. The HSP (phenol) of the substance can be greater than 0.5, can be greater than 1, can be greater than 2, and can be greater than 5.

[0049] As parameters that affect storage stability, vapor pressure Vp and dropping point DP can be cited. The reason for this is described below.

[0050] Flavored smoking articles are usually stored for a long time in a closed space covered with a polypropylene film. Additives added to components for flavored smoking articles such as filters may be transferred to tobacco during long-term storage. On the other hand, when the user inhales the flavor, in order to selectively filter specific components, it is necessary to keep the additives in the filter, etc.

[0051] The transfer of additives from filters etc. to tobacco shreds is mainly carried out via the gas phase. Therefore, in order to suppress this transfer, it is desirable that the additives contain a substance having a low vapor pressure.

[0052] The vapor pressure Vp of monoolein is 0 Pa at 25°C. It should be noted that in the specification and claims of the present application, when no temperature is recorded, the record of "vapor pressure" refers to the vapor pressure at 25°C. Based on the above reasons, the vapor pressure Vp of the substance contained in the phenol scavenger (additive) of the embodiment of the present invention is preferably 0 Pa at 25°C. However, the vapor pressure Vp at 25°C does not need to be 0 Pa, as long as it is below 0.2 Pa, the transfer of the scavenger to the tobacco is not likely to occur. This was discovered based on the evaluation of the transfer amount of tobacco described below.

[0053] (Evaluation of tobacco transfer amount)

[0054] First, the tobacco shreds 52 of one cigarette are disassembled and placed in the sealable first threaded vial 50. In this evaluation, the mass of the tobacco shreds of one cigarette is 560 mg. As the first threaded vial 50, specification No. 7 (volume 50 mL) manufactured by Maruemu Co., Ltd. is used. Prepare another second threaded vial 51, and put 0.5 mL of the evaluation object substance into the second threaded vial 51. As the second threaded vial 51, specification No. 1 (volume 4 mL) manufactured by Maruemu Co., Ltd. is used. The second threaded vial 51 filled with the evaluation object substance is placed inside the first threaded vial 50 without a cap, and the first threaded vial 50 is covered. In this way, a state in which the evaluation object substance and the tobacco shreds 52 coexist is formed in the sealed system in the first threaded vial 50. The first threaded vial 50 prepared in this way is stored in an environment of 55°C and 60%RH for 3 weeks. Figure 2 1 is a diagram schematically showing the state of storing the prepared first screw-thread vial 50. After the three-week storage, the amount of the evaluation object substance transferred to the shredded tobacco was quantified by gas chromatography.

[0055] This test was conducted on each of the five substances shown below. The evaluation target substances were ethylene glycol, propylene glycol, 1,3-butanediol, diethyl succinate, and tributyl phosphate.

[0056] The vapor pressure Vp of these substances at 25°C and the amount of transfer (adsorption) to tobacco shreds are summarized in the following Tables 1 and Figure 3 . Figure 3 For each substance, the amount of transfer to the tobacco shreds is plotted against the vapor pressure. Figure 3 In the graph shown, the horizontal axis is the vapor pressure Vp [Pa], and the vertical axis is the amount of transfer to the tobacco shreds [mmol / cig.]. Figure 3 In the table, EG represents ethylene glycol, PG represents propylene glycol, 1,3-BD represents 1,3-butanediol, DSU represents diethyl succinate, and TBP represents tributyl phosphate.

[0057] [Table 1]

[0058]

[0059] As shown in Table 1 and Figure 3 As shown, when tributyl phosphate having a vapor pressure Vp of 0.2 Pa or less is used, transfer to tobacco shreds basically does not occur. That is, by using a substance having a vapor pressure Vp of 0.2 Pa or less at 25°C, the transfer of the substance to tobacco shreds via the gas phase can be suppressed. The vapor pressure of the substance is more preferably 0.1 Pa or less, and more preferably substantially 0 Pa. According to one embodiment, the vapor pressure of the substance is within a range of 0 Pa or more and 0.20 Pa or less.

[0060] The phenol capture agent carried on the filter tip or the like may leak out from the filter tip or the like during storage, thereby causing stains on the cigarette wrapping paper or the tipping paper. In the case where the phenol capture agent contains a substance having a low dropping point, there is a tendency for such leakage to occur significantly. The storage temperature of cigarettes, for example, in a vending machine, is sometimes around 50° C. Therefore, as a substance containing a phenol capture agent, a substance that does not easily flow even in such an environment is preferred.

[0061] A substance with a dropping point (DP: Dropping Point) of 50°C or more is difficult to flow even under relatively high temperature storage conditions, such as in a high-temperature vending machine. Therefore, such a substance is not easy to cause stains on the rolling paper or the tipping paper even if used in a filter tip, etc. In addition, by using a phenol capture agent containing a substance that is not easy to leak out from a filter tip, etc., the substance is easy to be retained in the filter tip, etc., so a component with excellent phenol selective filtration ability can be realized. The dropping point of monoolein is 78°C, so it is not easy to flow during storage. The upper limit of the dropping point of the substance contained in the phenol capture agent is not particularly limited, for example, it is 150°C. The dropping point of the substance is preferably in the range of 50°C to 130°C. When the dropping point of the substance is too high, it may be difficult to load the phenol capture agent containing the substance on the filter tip, etc., so it is preferred. The dropping point of the substance can be measured based on JIS K2220:2013.

[0062] As described above, when a phenol-trapping agent containing a substance satisfying the above formulae (1) to (3) is supported on a base member constituting a flavor inhalation article, the flavor inhalation article including the member exhibits sufficient selective filtration capability for phenol and has excellent storage stability.

[0063] The fragrance inhalation article having excellent storage stability has a high ability to selectively filter phenol even after long-term storage, so that the fragrance can be maintained. That is, the taste of the fragrance inhalation article is not easy to change. In addition, the fragrance inhalation article of one embodiment can maintain a good appearance even after long-term storage.

[0064] It should be noted that the manner in which the phenol-trapping agent captures phenol is not particularly limited. The phenol-trapping agent may be a substance that physically adsorbs phenol or a substance that is compatible with phenol.

[0065] The substance contained in the phenol-trapping agent is not limited to glyceryl monooleate, and any substance can be used as long as it satisfies the conditions described above.

[0066] It should be noted that, generally, "dropping point" is a physical property determined for semi-solid substances at room temperature, such as grease. Here, "dropping point" is not only a physical property determined for semi-solid substances at room temperature, but also a physical property determined for solid substances at room temperature. The dropping point of a substance that is solid at room temperature is, for example, equal to its melting point.

[0067] Here, normal temperature refers to the range of 20°C ± 15°C specified in JIS Z8703 of Japanese Industrial Standards (JIS). In order to satisfy the requirement of being semi-solid at normal temperature, it is necessary to be semi-solid at 5°C and semi-solid at 35°C.

[0068] A semisolid substance refers to a non-Newtonian fluid that exhibits viscoelastic behavior. In other words, a semisolid substance is a composition or compound that does not flow at room temperature and under low shear force, but exhibits plastic, pseudoplastic or thixotropic flow behavior when the shear force is increased.

[0069] The substance contained in the phenol capture agent is, for example, at least one selected from monoolein, benzoic acid, ginger ketone, methylcyclopentenolone (cycloten) and maltol. The substances contained in this substance group all satisfy all of the above formulas (1) to (3). The substance contained in the phenol capture agent can be a mixture of two or more substances that satisfy all of the above formulas (1) to (3). The mixture can also satisfy the above formulas (1) to (3).

[0070] The phenol capturing agent may further contain a known plasticizer.

[0071] Another parameter that affects storage stability is the distribution coefficient LogP. The reason for this is described below.

[0072] As described above, during the storage period of the flavor smoking article, the phenol capture agent loaded on the filter tip can be transferred to the tobacco shreds mainly via the gas phase. In the case of a phenol capture agent containing a substance with high affinity to the tobacco shreds, the volatilized substance is absorbed (adsorbed) by the tobacco shreds quickly. Therefore, in the gas phase within the flavor smoking article, the partial pressure of the volatilized substance is easy to decrease. When the partial pressure of the substance in the gas phase is reduced, it becomes an environment where the substance from the filter tip is more likely to volatilize. Therefore, by using a phenol capture agent containing a substance with low affinity to the tobacco shreds, the substance basically reaches the saturated vapor pressure in the package and is easy to maintain a state of equilibrium. As a result, volatilization of the substance from the filter tip is not easy to occur.

[0073] The index for evaluating the affinity with tobacco shreds is the above-mentioned distribution coefficient LogP. The distribution coefficient LogP was originally an index indicating the hydrophobicity or transferability of a certain chemical substance. Here, the distribution coefficient LogP refers to the octanol / water distribution coefficient (LogPow) using water and n-octanol at 25°C. The distribution coefficient LogP is a value obtained by actually measuring the equilibrium solubility ratio when a substance is dissolved in a liquid consisting of two phases of water and octanol, and is expressed as P = (substance concentration in octanol phase) / (substance concentration in water phase). Therefore, the larger the value of the distribution coefficient LogP, the higher the hydrophobicity of a certain substance.

[0074] Among the components contained in tobacco shreds, the component that absorbs substances that can capture phenol is mainly water. Therefore, by using a substance with a large LogP, i.e., a substance with high hydrophobicity, as a substance that can capture phenol, an environment in which the partial pressure of the substance is not easily reduced can be achieved in the flavor smoking article. In other words, substances with a large LogP are not easy to volatilize from filters, etc., and therefore can be retained in filters, etc. for a long period of time.

[0075] The distribution coefficient LogP of the substance contained in the phenol scavenger is preferably 4.5 or more at 25°C. This is found based on the above-mentioned evaluation of the transfer amount to tobacco shreds. For the substances evaluated in the above-mentioned evaluation of the transfer amount to tobacco shreds, the LogP at 25°C and the transfer amount (adsorption amount) to tobacco shreds are summarized in the following Tables 2 and 3. Figure 4 . Figure 4 This is a graph that plots the amount of each substance transferred to the tobacco shreds versus the distribution coefficient LogP. Figure 4 In the graph shown, the horizontal axis is LogP and the vertical axis is the amount of transfer to tobacco shreds [mmol / cig.]. Figure 4 The symbols used in Figure 3 The symbols used in have the same meaning.

[0076] [Table 2]

[0077]

[0078] As shown in Table 2 and Figure 4 As shown in FIG. 1 , when tributyl phosphate having a distribution coefficient LogP of 4.5 or more is used, transfer to tobacco shreds basically does not occur. That is, substances having a distribution coefficient LogP of 4.5 or more at 25°C have poor affinity with tobacco shreds and are therefore not easily volatilized from filters or the like. Therefore, the transfer of the substance to tobacco shreds via the gas phase can be suppressed. The distribution coefficient LogP of the substance is more preferably 6 or more. The upper limit of the distribution coefficient LogP of the substance is not particularly limited, and is, for example, 29.

[0079] The distribution coefficient LogP of monoolein is 6.4. Therefore, it is not easy for monoolein to transfer to the tobacco shreds. The substance contained in the phenol capturing agent according to the embodiment of the present invention is preferably monoolein.

[0080] Regarding the benzoic acid, zingerone, methylcyclopentenolone, and maltol exemplified above as the above substances included in the phenol scavenger, HSP (phenol), vapor pressure Vp, dropping point, and partition coefficient LogP are shown.

[0081] Benzoic acid has a HSP (phenol) of 5.17, a vapor pressure Vp of 0.001 Pa at 25°C, a dropping point of 122°C, and a LogP of 1.87.

[0082] The HSP (phenol) of zingerone is 5.56, the vapor pressure Vp at 25°C is 0 Pa, the dropping point is 54°C, and the LogP is 1.54.

[0083] The HSP (phenol) of methylcyclopentenolone (Cyclotene) is 5.37, the vapor pressure Vp at 25°C is 0.029 Pa, the dropping point is 71°C, and the LogP is 0.22.

[0084] The HSP (phenol) of maltol is 6.89, the vapor pressure Vp at 25°C is 0.002 Pa, the dropping point is 78°C, and the LogP is -0.26.

[0085] The material contained in the phenol trapping agent is preferably semisolid at room temperature. When the material is semisolid, the surface area when loaded on the fragrance suction article component can be increased compared with the case where it is solid. Therefore, when the material is semisolid, the contact probability with the component phenol to be captured can be increased, so the phenol selective filtering ability can be improved. In addition, when the material is semisolid, the material is not easy to leak out from the loaded component compared with the case where it is liquid. Therefore, even if the material is semisolid at room temperature, it can also be made not easy to produce stains on the roll paper or the tipping paper.

[0086] A component for a flavor inhalation article of one embodiment includes a base component. The base component is, for example, a component for a flavor inhalation article used in combination with a tobacco material. The base component may be at least one of a component constituting a smoking article, a component constituting a non-burning and heating type flavor inhalation article, and a component constituting a non-burning and non-heating type flavor inhalation article. A smoking article is an article that provides tobacco flavor to a user by burning a tobacco material. A non-burning and heating type flavor inhalation article is an article that provides tobacco flavor to a user by heating without burning the tobacco material. A non-burning and non-heating type flavor inhalation article is an article that provides tobacco flavor to a user without burning or heating the tobacco material. An example of the tobacco material is shredded tobacco. The material of the shredded tobacco is not particularly limited, and known materials such as leaves and leaf veins may be used.

[0087] <2. Scented items>

[0088] Hereinafter, a cigarette will be described as a representative example of a smoking article containing a tobacco material with reference to the drawings.

[0089] <2-1. Smoking articles>

[0090] Reference Figure 5 An example of a smoking article will be described.

[0091] Figure 5 It is a cross-sectional view of the smoking article 1 . Figure 5 The smoking article 1 shown is a cigarette.

[0092] Figure 5 The smoking article 1 shown includes a cigarette rod 11, a filter 12 and a tipping paper 13. The cigarette rod 11 includes a tobacco material 11a (shredded tobacco) and a wrapping paper 11b that wraps around the tobacco material 11a. Here, the filter 12 is formed by a single filter plug. The filter plug includes a filter material 12a and a wrapping paper 12b that is wrapped around the filter material 12a. The tipping paper 13 is wrapped around the cigarette rod 11 and the filter 12 in a manner that connects the cigarette rod 11 and the filter 12.

[0093] The base member included in the member for flavor inhalation article according to one embodiment is, for example, at least one selected from the group consisting of the wrapping paper 11b, the filter material 12a, the winding paper 12b, and the tipping paper 13. The phenol capturing agent is supported on the base member.

[0094] The amount of the above-mentioned substance contained in the phenol capture agent is, for example, in the range of 5 to 35 parts by mass relative to 100 parts by mass of the base member, preferably in the range of 10 to 30 parts by mass. The amount can be in the range of 5 to 15 parts by mass, can be in the range of 15 to 25 parts by mass, or can be in the range of 25 to 35 parts by mass. When the amount is too small, the absolute amount of phenol that can be filtered is reduced, so it is not preferred. When the amount is too much, the phenol capture agent may leak from the component for the flavor inhalation article and produce stains on the rolling paper, winding paper and / or tipping paper possessed by the flavor inhalation article, and may also produce stains on the packaging of the flavor inhalation article according to the circumstances. That is, the appearance of the flavor inhalation article, etc. may be damaged, so it is not preferred. As shown in the embodiments described later, in order to improve the time stability of the phenol selective filtration ability under relatively high temperature storage conditions (for example, above 35°C), the above-mentioned substance loaded in the base member is preferably in the range of 5 to 15 parts by mass.

[0095] The base member loaded with the phenol capture agent is preferably further loaded with an antioxidant. In particular, when the substance contained in the phenol capture agent is a highly unsaturated fatty acid such as monoolein, the highly unsaturated fatty acid produces a special smell due to oxidation. By further loading an antioxidant in the base member, the oxidation of the above-mentioned substance can be suppressed, and therefore, the generation of the special smell is suppressed, and an excellent fragrance can be maintained. Examples of antioxidants include tocopherol.

[0096] The base member may further include an adsorbent for improving the phenol selective filtering capability, a capsule for controlling the release of flavors, or a colorant, etc. Various adsorbent particles such as activated carbon particles may be loaded in the base member.

[0097] The filter material preferably comprises a sheet material. The sheet material is preferably, for example, Figure 7 The corrugated film 121 is a film with corrugated folds, that is, a film in which ridges 21a and valleys 21b are arranged alternately (see Figure 7 ).

[0098] Figure 6 1 shows a cross-sectional view of a filter 12, which is provided with a filter material 12a formed by a corrugated film 121 and a winding paper 12b that is wrapped with the filter material 12a. Here, in the filter material 12a, the corrugated film 121 is bent or folded in a manner to form a plurality of air flow paths 122 that extend respectively from the end face of the tobacco material side to the end face of the suction port side. As a device for wrapping such a corrugated film with winding paper, for example, it is disclosed in Japanese Patent Publication No. 2002-204683 Gazette, Japanese Patent Publication No. H09-294577 Gazette, and Japanese Patent Publication No. H09-294576 Gazette.

[0099] Examples of the sheet material include paper and films formed from a molten film material. Examples of the film formed from a molten film material include films made of thermoplastic resins.

[0100] The sheet material is preferably paper. Paper is a highly biodegradable material and is therefore preferred from the viewpoint of environmental protection.

[0101] Among them, the filter using paper as the sheet material, i.e., the paper filter, has a low ability to filter semi-volatile components such as phenol when no additives such as phenol capture agents are loaded. In addition, for the paper filter, from the viewpoint of large specific surface area, when additives such as phenol capture agents are loaded, the volatilization is easy to occur. Therefore, as a filter loaded with the phenol capture agent according to an embodiment of the present invention, when a paper filter is used, the effect of improving storage stability is high compared with the case where other filter tips are used.

[0102] The weight per unit area of ​​paper is, for example, 20 g / m 2 ~120g / m 2 In the range of 25 g / m 2 ~45g / m 2 In the case of a filter tip length of 120 mm, the air flow resistance of the filter tip including paper as the filter material is, for example, in the range of 100 mmAq to 800 mmAq, preferably in the range of 200 mmAq to 600 mmAq. The unit area weight of the paper is preferably about 40 g / m 2 In the case of a filter having a length of 120 mm, the air flow resistance of a filter including paper as a filter material is preferably about 400 mmAq.

[0103] The filter material may be composed of acetate fiber bundles, which may have, for example, a single fiber fineness of 1.9 to 8.6 (g / 9000m), a total fineness of 17000 to 44000 (g / 9000m), a fiber count of 2400 to 23500 (fibers), and an air flow resistance of 100 to 600 (mmH2O / 120mm).

[0104] The filter tip may have more than two filter rods. When the filter tip includes a plurality of filter rods, the filter rod on the tobacco material side and the filter rod on the mouthpiece side may have the same raw materials and structure, or may have different raw materials and structures. When the filter tip has two filter rods, for example, a paper filter tip may be used as one filter rod, and a cellulose acetate filter tip or a charcoal filter tip may be used as another filter rod. When the filter tip has more than two filter rods, it is preferred that a phenol capture agent is loaded in at least one of the filter rods.

[0105] The filter rod containing the phenol capturing agent according to the embodiment of the present invention is preferably not in contact with the tobacco rod. In this case, by contacting the filter rod containing the phenol capturing agent with the tobacco material, the transfer of the phenol capturing agent to the tobacco material can be suppressed.

[0106] As the cigarette rod, a known cigarette rod can be used. The cigarette rod, for example, includes a tobacco material and a wrapping paper wrapped around it, and can have a circumference of about 14 to 26 mm and a length of 15 to 70 mm. The wrapping paper is preferably oil-resistant. When using oil-resistant wrapping paper, even if the phenol capture agent leaks from the base member, it is not easy to cause stains.

[0108] The member for flavor inhalation article of one embodiment may be one of the members constituting the non-combustion heating type flavor inhalation article. Figure 8 to Figure 10 An example of a non-combustion heating type flavor inhalation article is described, and an example of an aerosol generating device used by a user when heating the non-combustion heating type flavor inhalation article is described.

[0109] Figure 8 It is a perspective view showing an example of a heating type flavor inhaler. Fig. 9 It is a cross-sectional view of a scent inhalation article. Fig.10 It is a diagram showing the internal structure of the aerosol generating device.

[0110] like Figure 8 As shown, the aroma inhaler 100 has:

[0111] A flavor smoking article 110 comprising a tobacco material and an aerosol source, and

[0112] The aerosol generating device 120 heats the flavor inhalation article 110 to atomize the aerosol source and release the flavor component from the tobacco material.

[0113] The flavor inhalation article 110 is a replaceable cartridge having a columnar shape extending in one direction. The flavor inhalation article 110 is configured to be heated when inserted into the aerosol generating device 120 to generate aerosol and flavor components.

[0114] like Fig. 9 As shown, the flavor inhalation article 110 has a base portion 110A forming one end thereof and a mouthpiece 110B forming an end opposite to the base portion 110A, wherein the base portion 110A includes a filler 111 and a first roll paper 112 for wrapping the filler 111. The base portion 110A and the mouthpiece 110B are connected together by a second roll paper 113.

[0115] The mouthpiece 110B has a paper tube 114 and a filter 118 adjacent thereto. The filter 118 has a filter rod 115, a hollow rod 116, and a molded paper 117 that connects them together by covering. The paper tube 114 is a paper tube formed by rolling paper into a cylindrical shape, and the inside is a cavity. The hollow rod 116 is arranged between the paper tube 114 and the filter rod 115.

[0116] The filter rod 115 includes a filter medium 102 and a first rod winding paper 101 that wraps the filter medium 102. The filter medium 102 is preferably a paper filter. As the filter medium 102, a cellulose acetate filter or a charcoal filter can be used.

[0117] The hollow rod 116 has a filling layer 104 and a second rod winding paper 103 that is wound around the filling layer 104. The filling layer 104 is composed of fibers filled with high density and has one or more channels (hollow parts). One or more channels extend along the length direction (hereinafter referred to as the length direction) of the flavor inhalation article 110. Therefore, when inhaling, air and aerosol only flow through the channels and basically do not flow through the gaps between the fibers. For the flavor inhalation article 110, when it is desired to reduce the aerosol components in the filter rod 115 due to filtration, shortening the length of the filter rod 115 and replacing it with a hollow rod 116 is effective for increasing the transport amount of the aerosol.

[0118] Filter 118 Fig. 9 As shown, the filter 118 may be provided with more than two filter rods or only one. For example, the filter 118 may omit the hollow rod 116 and only have the filter rod 115. That is, the paper tube portion 114 and the filter rod 115 may be arranged adjacent to each other to form the mouthpiece 110B. In the case where the filter 118 is provided with more than two filter rods, as described in the smoking article, it is preferred that at least one of the plurality of filter rods is loaded with the phenol capture agent according to an embodiment of the present invention.

[0119] When the filter 118 has two or more filter plugs, the filter plug loaded with the phenol capturing agent may be disposed at a position corresponding to the end of the mouthpiece 110B on the mouthpiece side, for example, Fig. 9 The position of the filter rod 115 shown can also be set at a position equivalent to the position of the hollow rod 116.

[0120] The mouthpiece 110B is composed of two sections, namely the paper tube 114 and the filter 118 . The mouthpiece 110B may be composed of one section or three or more sections.

[0121] It should be noted that, although not shown in the figure, in order to appropriately adjust the ventilation resistance of the flavor inhalation article 110, an opening portion may be provided in the mouthpiece 110B to introduce air from the outside. In this case, it is preferred that the paper tube 114 is provided with an opening portion.

[0122] The base member included in the member for flavor inhalation article of one embodiment is, for example, at least one selected from the first roll paper 112, the second roll paper 113, the paper tube 114, the filter 118, and the plug-in paper 117. The base member loaded with the phenol capture agent is preferably at least one of the members constituting the filter 118. The base member loaded with the phenol capture agent is more preferably at least one selected from the filter material 102 and the filling layer 104.

[0123] The dimension of the length direction of the flavor inhalation article 110, i.e., the length, is preferably 40 to 90 mm, more preferably 50 to 75 mm, and further preferably 50 to 60 mm. The circumference of the flavor inhalation article 110 is preferably 15 to 25 mm, more preferably 17 to 24 mm, and further preferably 20 to 23 mm. In addition, in the flavor inhalation article 110, the length of the base material portion 110A may be 20 mm, the length of the paper tube portion 114 may be 20 mm, the length of the hollow rod 116 may be 8 mm, and the length of the filter rod 115 may be 7 mm. The lengths of these sections may be appropriately changed according to manufacturing adaptability, required quality, etc.

[0124] The filler 111 contains tobacco material and an aerosol source.

[0125] The aerosol source is heated at a given temperature to generate an aerosol. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3-butylene glycol, and mixtures thereof. The content of the aerosol source in the filler 111 is not particularly limited, but is generally 5% by mass or more, preferably 10% by mass or more, and is generally 50% by mass or less, preferably 25% by mass or less, from the perspective of generating a sufficient amount of aerosol and imparting a good flavor.

[0126] The filler 111 contains tobacco material as a flavor source. The tobacco material is, for example, shredded tobacco. When the base material 110A has a circumference of 22 mm and a length of 20 mm, the content of the filler 111 in the flavor inhalation article 110 is, for example, 200 to 400 mg, preferably 250 to 320 mg. The moisture content of the filler 111 is, for example, 8 to 18% by mass, preferably 10 to 16% by mass. When such a moisture content is set, the generation of rolling stains can be suppressed, so that the base material 110A has good rolling adaptability during manufacturing.

[0127] There are no particular restrictions on the size of the shredded tobacco used in the filler 111 and the method for preparing the shredded tobacco. For example, shredded tobacco obtained by cutting dried tobacco leaves into pieces with a width of 0.8 to 1.2 mm can be used. In addition, shredded tobacco obtained by grinding dried tobacco leaves to an average particle size of about 20 to 200 μm and homogenizing them and then cutting them into pieces with a width of 0.8 to 1.2 mm can also be used. In addition, the processed product obtained by the above-mentioned piece processing can be pleated without cutting, and the obtained product can be used as a tobacco material.

[0128] The same materials as the cigarette wrapping paper and the tipping paper used in cigarettes can be used as the first wrapping paper 112 and the second wrapping paper 113. In addition, the same materials as the cigarette wrapping paper used in cigarettes can be used as the first rod wrapping paper, the second rod wrapping paper and the plugging paper 117.

[0129] like Fig.10 As shown, the aerosol generating device 120 has an insertion hole 130 into which the flavor inhalation article 110 can be inserted. That is, the aerosol generating device 120 has an inner cylindrical member 132 constituting the insertion hole 130. The inner cylindrical member 132 can be made of a thermally conductive material such as aluminum or stainless steel (SUS).

[0130] In addition, the aerosol generating device 120 may include a cover 140 for closing the insertion hole 130. The cover 140 is slidable and can be switched between a state of closing the insertion hole 130 and a state of exposing the insertion hole 130 (see Figure 8 ) to change state.

[0131] The aerosol generating device 120 may include an air flow path 160 communicating with the insertion hole 130. One end of the air flow path 160 is connected to the insertion hole 130, and the other end of the air flow path 160 communicates with the outside of the aerosol generating device 120 (external air) at a location different from the insertion hole 130.

[0132] The aerosol generating device 120 may include a cover 170 covering the end of the air flow path 160 communicating with the outside air. The cover 170 may cover the end of the air flow path 160 communicating with the outside air, or may expose the end.

[0133] Here, the cover 170 covers the end of the air flow path 160, but does not hermetically seal the air flow path 160. That is, the cover 170 is configured such that, although it covers the air flow path 160, it is separated from the end of the air flow path 160, and external air can flow into the air flow path 160 from the gap therebetween.

[0134] The user inserts the flavor inhalation article 110 into the aerosol generating device 120 and holds one end of the flavor inhalation article 110 in his mouth. Fig. 9 The mouthpiece 110B shown in the figure is used for inhalation. Through the inhalation action of the user, external air flows into the air flow path 160. The air flowing into the air flow path 160 is introduced into the user's oral cavity through the flavor inhalation article 110 inserted into the hole 130.

[0135] The aerosol generating device 120 may include a temperature sensor in the air flow path 160 or on the outer surface of the wall constituting the air flow path 160. The temperature sensor may be, for example, a thermistor, a thermocouple, etc. When the user inhales the mouthpiece 110B of the flavor inhalable article 110, the temperature inside the air flow path 160 or the temperature of the wall constituting the air flow path 160 decreases due to the influence of the air flowing in the air flow path 160 from the cover 170 side toward the heater 30 side described later. The temperature sensor can detect the user's inhalation action by measuring the temperature decrease.

[0136] The aerosol generating device 120 includes a battery 10, a control unit 20, and a heater 30. The battery 10 stores electric power used by the aerosol generating device 120. The battery 10 may be a rechargeable and dischargeable secondary battery. For example, the battery 10 may be a lithium ion battery.

[0137] The heater 30 may be provided around the inner cylinder member 132. The space accommodating the heater 30 and the space accommodating the battery 10 may be separated from each other by the partition 180. Thus, the air heated by the heater 30 can be suppressed from flowing into the space accommodating the battery 10. Therefore, the temperature rise of the battery 10 can be suppressed.

[0138] The heater 30 is preferably a cylindrical shape that can heat the outer periphery of the columnar flavor inhalation article 110. The heater 30 can be, for example, a film heater. The film heater can have a pair of film-like substrates and a resistive heating element sandwiched between the pair of substrates. The film-like substrate is preferably made of a material with excellent heat resistance and electrical insulation, typically made of polyimide. The resistive heating element is preferably made of one or more of metal materials such as copper, nickel alloy, chromium alloy, stainless steel, platinum rhodium, etc., for example, it can be formed of a stainless steel substrate. In addition, for the resistive heating element, in order to connect to a power source via a flexible printed circuit (FPC), copper plating can be applied to the connection portion and its lead portion.

[0139] Preferably, the heat shrink tube is disposed outside the heater 30. The heat shrink tube is a tube that shrinks in the radial direction by heat, and is composed of, for example, a thermoplastic elastomer. The heater 30 is pressed against the inner tube member 132 by the shrinking action of the heat shrink tube. As a result, the close fit between the heater 30 and the inner tube member 132 is increased, and thus the thermal conductivity from the heater 30 to the flavor inhalation article 110 via the inner tube member 132 is increased.

[0140] The aerosol generating device 120 has a cylindrical insulating material on the outside of the heater 30 in the radial direction, preferably on the outside of the heat shrink tube. The insulating material prevents the outer surface of the frame of the aerosol generating device 120 from reaching excessively high temperatures by isolating the heat of the heater 30. The insulating material can be made of aerogels such as silica aerogel, carbon aerogel, and alumina aerogel. Aerogel as an insulating material can be representatively silica aerogel with high thermal insulation performance and low manufacturing cost. Among them, the insulating material can be a fiber insulating material such as glass wool and rock wool, or a foaming insulating material such as polyurethane foam and phenolic foam. Alternatively, the insulating material can be a vacuum insulating material.

[0141] An outer tube member 134 is provided outside the heat insulating material. The heat insulating material may be provided between the inner tube member 132 facing the flavor inhalation article 110 and the outer tube member 134. The outer tube member 134 may be made of a heat conductive material such as aluminum or stainless steel (SUS). The heat insulating material is preferably provided in a closed space.

[0142] The control unit 20 may include a circuit board, a central processing unit (CPU), a memory, etc. In addition, the aerosol generating device 120 may have a notification unit for notifying the user of various information under the control of the control unit 20. The notification unit may be a light emitting element such as a light emitting diode (LED) or a vibration element, or a combination thereof.

[0143] After the control unit 20 detects the user's start request, it starts supplying power from the battery 10 to the heater 30. The user's start request is realized, for example, by the user's button, the operation of the slide switch, or the user's puffing action. The user's start request can be realized by pressing the button 150. More specifically, the user's start request can be realized by pressing the button 150 in a state where the cover 140 is opened. Alternatively, the user's start request can be realized by detecting the user's puffing action. The user's puffing action can be detected, for example, by the above-mentioned temperature sensor.

[0144] <2-3. Non-burning and non-heating aroma inhalation products>

[0145] The component for flavor inhalation articles of one embodiment may be a component for non-burning and non-heating flavor inhalation articles that provide the user with the flavor of tobacco materials without heating or burning tobacco materials. As non-burning and non-heating flavor inhalation articles, there can be cited a non-heating tobacco flavor inhaler that includes a refillable cigarette cartridge containing tobacco materials in a suction frame and allows the user to inhale tobacco flavor from tobacco materials at room temperature (see, for example, WO2012 / 023515).

[0146] A flavor inhalation article of one embodiment includes a flavor inhalation article member, wherein the flavor inhalation article member includes a base member and a phenol capture agent supported on the base member and containing a substance satisfying the above formulas (1) to (3).

[0148] The member for a flavor inhalation article according to one embodiment can be produced by a method including supporting a phenol-trapping agent including a substance satisfying the above formulae (1) to (3) on a base member.

[0149] As a method for loading the phenol trapping agent on the base member, for example, there is a method comprising heating the substance to a temperature above the dropping point to make it flow and then loading it on the base member. Alternatively, there is a method comprising: dissolving the substance in a suitable organic solvent, preparing a solution, supplying the solution to the base member, and then removing the organic solvent to load the substance on the base member.

[0150] Examples of the organic solvent for dissolving the above substances include triacetin, propylene glycol, ethanol, and glycerin.

[0151] The method for loading the fluidized substance on the base member is not particularly limited. For example, the fluidized substance may be applied to the base member or may be impregnated therein. By applying or impregnating the fluidized substance on the base member, the substance may be uniformly loaded on the base member.

[0152] The application of the substance to the base member can be performed by, for example, spraying. The penetration of the substance into the base member can be performed by, for example, dropping the substance using a syringe.

[0177] Example

[0178] Hereinafter, examples will be described, but the present invention is not limited to the examples described below.

[0179] [Example 1] Evaluation of phenol selective filtration capability

[0180] <Cigarette Sample Production>

[0181] (Preparation of Cigarette Sample 1)

[0182] First, a paper filter with a length of 27 mm and a diameter of 7.7 mm was prepared. Specifically, first, a corrugated paper (weight per unit area 40 g / m 2 ) was bent or folded in a manner to form a plurality of air flow paths extending from one end to the other end, thereby producing a rod having a length of 120 mm and a ventilation resistance of 400 mmAq. The rod was cut into a length of 27 mm and wound with a paper tube having a length of 27 mm and a diameter of 7.7 mm as a winding paper to produce a paper filter.

[0183] Next, the filter material of the filter tip was loaded with 10 parts by mass of commercially available monoolein (MGO) relative to 100 parts by mass. When loading the monoolein, it was heated to 50°C to fluidize it, and then loaded with a microsyringe in a uniform mass along the length direction of the filter material. Then, a commercially available Mevius Superlite cigarette rod was joined to the filter tip to produce cigarette sample 1.

[0184] (Production of Cigarette Sample 2)

[0185] Cigarette Sample 2 was prepared by the same method as Cigarette Sample 1, except that the amount of monoolein supported on the filter medium was 20 parts by mass.

[0186] (Production of Cigarette Sample 3)

[0187] Cigarette Sample 3 was prepared by the same method as Cigarette Sample 1 except that the amount of monoolein supported on the filter medium was 30 parts by mass.

[0188] (Production of Cigarette Samples 4 to 6)

[0189] Cigarette Samples 4 to 6 were prepared respectively by the same method as Cigarette Samples 1 to 3 except that triacetin (GTA) was used instead of monoolein.

[0190] It should be noted that the HSP (phenol) of triacetin is 7.18, the vapor pressure Vp is 0 Pa, the dropping point DP is 4° C., and the distribution coefficient LogP is 0.25.

[0191] (Production of Cigarette Sample 7)

[0192] Cigarette Sample 7 was produced by the same method as Cigarette Sample 1 except that no additive was loaded on the filter medium.

[0193] (Production of Cigarette Sample 8)

[0194] Cigarette Sample 8 was produced by the same method as Cigarette Sample 1, except that only a paper tube was joined to the cigarette rod instead of the filter. Cigarette Sample 8 was used as a standard sample.

[0195] <Smoking test>

[0196] The eight cigarette samples were subjected to smoking tests according to ISO smoking conditions immediately after production, after storage at 22°C 60% RH for one month, and after storage at 35°C 60% RH for one month.

[0197] Specific smoking conditions are as follows. Using an automatic smoking machine (Cerulean SM410), the automatic smoking of cigarette samples was carried out under the conditions of a smoking capacity of 17.5 mL / second, a smoking time of 2 seconds / mouth, and a smoking frequency of 1 mouth / minute, and the total particulate matter (TPM) in tobacco smoke was captured using a Cambridge filter (Borgwaldt 44 mmΦ). The TPM mass was measured based on the mass difference of the Cambridge filter before and after smoking. Then, the Cambridge filter was immersed in 10 mL of the phenol extraction solvent shown in the following Table 3 loaded into a threaded tube bottle, and oscillated to obtain an analytical sample. 1 μL of the analytical sample obtained was collected with a microsyringe and analyzed using a gas chromatograph (GC-MSD: Gas Chromatography-Mass Selective Detector). As a GC, an Agilent G7890A manufactured by Agilent Technologies Inc was used, and as an MSD, an Agilent_5795C manufactured by Agilent Technologies Inc. was used.

[0198] [Table 3]

[0199] Compound concentration Solvents Tert-Butyl Methyl Ether - Internal Standard o-Chlorophenol 9.15μg / ml

[0200] The TPM mass per cigarette and the amount of phenol in tobacco smoke were measured for each cigarette sample by the above method. The phenol selective filtration index Sx described below was calculated from these results, and the temporal stability of the phenol capture capacity was evaluated based on the index.

[0201] Specifically, first, the above-mentioned component amounts were substituted into the following formulas (I) and (II), and the TPM filtration efficiency E was calculated for each cigarette sample. TPM And phenol filtration efficiency E phenol .

[0202] E TPM =(A TPM,std -A TPM,smp ) / (A TPM,std )···(I)

[0203] E phenol =(A phenol,std -A phenol,smp ) / (A phenol,std )···(II)

[0204] In the above formula (I), A TPM,std is the TPM of cigarette sample 8 as the standard sample, A TPM,smp is the TPM amount of each cigarette sample. In the above formula (II), A phenol,stdis the amount of phenol in the smoke of cigarette sample 8 as the standard sample, A phenol,smp is the amount of phenol in the smoke of each cigarette sample.

[0205] It should be noted that for each cigarette sample, two samples produced under the same conditions were prepared and the above test was performed on each of them. Thus, for the cigarette samples produced under the same conditions, the TPM filtration efficiency E TPM And phenol filtration efficiency E phenol The two values ​​were averaged to determine the TPM filtration efficiency E of the corresponding cigarette sample. TPM And phenol filtration efficiency E phenol .

[0206] Next, for each cigarette sample, the obtained TPM filtration efficiency E TPM And phenol filtration efficiency E phenol Substituting into the following formula (III), the phenol selectivity filtration index Sx is calculated. In the formula (III), (1-E TPM ) represents the TPM transmittance, (1-E phenol ) represents the phenol permeability.

[0207] Sx=(1-E TPM ) / (1-E phenol )···(III)

[0208] The phenol selectivity filtration index Sx in the above formula (III) is (1-E TPM ) and (1-E phenol ) ratio, the higher the phenol selective filtration index Sx, the higher the phenol selective filtration ability of the corresponding cigarette sample. For example, for a certain cigarette sample, when the amount of phenol filtered is large, the phenol permeability (1-E phenol ) is small, so Sx is a large value.

[0209] The above results are summarized in Table 4 below.

[0210] It should be noted that in the following Table 4, the column titled "Sample No." records the number of the cigarette sample used in the test and the number of the storage condition corresponding to the cigarette sample in sequence, connected by hyphens. Specifically, for the test conducted just after production, the storage condition number is recorded as "1" after the cigarette sample number. For the test after 1 month of storage in a 22°C 60% RH environment, the storage condition number is recorded as "2" after the cigarette sample number. For the test after 1 month of storage in a 35°C 60% RH environment, the storage condition number is recorded as "3" after the cigarette sample number.

[0211] For example, the test conducted on cigarette sample 1 just after it was produced was assigned the number "1-1", the test conducted on cigarette sample 1 after it was stored in an environment of 22°C and 60% RH for one month was assigned the number "1-2", and the test conducted on cigarette sample 1 after it was stored in an environment of 35°C and 60% RH for one month was assigned the number "1-3".

[0212]

[0213] The results obtained for the cigarette sample 7 to which no phenol trapping agent was added were compared with the results obtained for the cigarette sample 1 to which 10 parts by mass of MGO was added as a phenol trapping agent. As shown in Table 4, the phenol selective filtration index Sx of the cigarette sample 1 to which MGO was added as a phenol trapping agent was high under any storage conditions. That is, the cigarette sample to which monoolein was added had sufficient phenol selective filtration capability. Similarly, cigarette samples 2 and 3 showed sufficient phenol selective filtration capability.

[0214] [Example 2] Evaluation of the stability of phenol selective filtration ability over time

[0215] In order to evaluate the temporal stability of the phenol selective filtration ability, the ratio of the phenol selective filtration index Sx after storage (sample number 1-2 or 1-3) to the phenol selective filtration index Sx just after production (sample number 1-1) [Sx (after storage) / Sx (before storage)] was calculated for cigarette sample 1. The ratio [Sx (after storage) / Sx (before storage)] is an indicator for evaluating storage stability.

[0216] Similarly, the ratio [Sx (after storage) / Sx (before storage)] of each of the cigarette samples 2 to 6 was calculated. These results are also shown in the above Table 4. It should be noted that for the cigarette sample 7 to which the phenol capture agent was not added, the value of Sx after storage was basically the same as the value of Sx before storage, so the ratio [Sx (after storage) / Sx (before storage)] was not calculated.

[0217] The results obtained for a plurality of cigarette samples having the same storage conditions are summarized in a graph according to each storage condition and are shown in FIG. Fig.11 and Fig.12 . Fig.11 This is a graph showing the ratio of the phenol selective filtration index Sx before and after storage for one month in an environment of 22°C and 60%RH [Sx (after storage) / Sx (before storage)]. Fig.12 This is a graph showing the ratio of the phenol selective filtration index Sx before and after storage for one month in an environment of 35°C and 60% RH [Sx (after storage) / Sx (before storage)]. The closer the ratio [Sx (after storage) / Sx (before storage)] is to 1, the smaller the change in the phenol selective filtration index Sx before and after storage is.

[0218] like Fig.11 As shown, the ratio [Sx (after storage) / Sx (before storage)] of cigarette samples 1 to 3 to which MGO as a phenol scavenger was added was close to 1 regardless of the amount of addition, compared with cigarette samples 4 to 6 to which GTA was added. That is, under the condition of storage for 1 month at 22°C and 60%RH, the storage stability of cigarette samples using MGO as a phenol scavenger was superior to that of cigarette samples using GTA as a phenol scavenger.

[0219] In addition, if Fig.12 As shown, the ratio [Sx (after storage) / Sx (before storage)] of cigarette samples 1 to 3 to which MGO as a phenol scavenger was added was close to 1 regardless of the amount of addition, compared with cigarette samples 4 to 6 to which GTA was added. That is, under the condition of storage for 1 month at 35°C and 60%RH, the cigarette samples to which MGO as a phenol scavenger was used had excellent storage stability compared with the cigarette samples to which GTA was used as a phenol scavenger.

[0220] It should be noted that, according to the results obtained when cigarette sample 1 was stored under condition 3, the ratio [Sx (after storage) / Sx (before storage)] was higher than 1. Although the reason is not clear, it is known that when the flavored inhalation article is stored in a relatively high temperature environment, that is, in an environment of 35°C and 60% RH, when the amount of MGO is set to about 10 parts by mass relative to 100 parts by mass of the base member, Sx after storage is higher than Sx before storage, which is particularly preferred.

[0222] <Production of filter samples>

[0223] (Preparation of filter sample A)

[0224] First, a paper filter with a length of 27 mm and a diameter of 7.7 mm was prepared. Specifically, a corrugated paper was bent or folded in a manner to form a plurality of air flow paths extending from one end to the other end, thereby preparing a rod with a length of 120 mm and a ventilation resistance of 400 mmAq. The rod was cut into a length of 27 mm, and the filter material obtained was wound into a paper tube with a length of 27 mm and a diameter of 7.7 mm as a winding paper to prepare a paper filter.

[0225] Next, the filter was placed on thick paper (Rengo), and commercially available monoolein (MGO) heated to 50°C and flowing was dripped onto the upper end surface of the filter using a micro syringe. The dripping amount was 10 parts by mass relative to 100 parts by mass of the filter material (excluding the paper tube). It should be noted that the dripping amount was an amount to the extent that the flowing MGO did not contact the thick paper.

[0226] As described above, filter sample A was produced.

[0227] (Production of filter sample B)

[0228] Filter Sample B was prepared in the same manner as Filter Sample A except that the amount of glyceryl monooleate supported on the filter medium was 20 parts by mass.

[0229] (Preparation of filter sample C)

[0230] Filter Sample C was prepared in the same manner as Filter Sample A except that the amount of glyceryl monooleate supported on the filter medium was 30 parts by mass.

[0231] (Production of filter samples D to F)

[0232] Filter samples D to F were prepared respectively in the same manner as filter samples A to C except that triacetin (GTA) was used instead of monoolein.

[0233] <Leakage test>

[0234] The six filter samples were placed on the thick paper and stored at 22°C 60% RH for one month, and the leakage of MGO or GTA to the thick paper after storage was confirmed by visual observation. In addition, the six filter samples were placed on the thick paper and stored at 35°C 60% RH for one month, and the leakage of MGO or GTA to the thick paper after storage was confirmed by visual observation. Fig.13 The photographs show thick paper after being stored in a 22° C. 60% RH environment for one month. Fig.14 The photographs show thick paper after being stored in a 35° C. 60% RH environment for one month.

[0235] For the filter samples D to F containing triacetin (GTA), stains were clearly observed on the thick paper after storage for 1 month at 22°C 60% RH and 1 month at 35°C 60% RH. Sample D, to which triacetin was added in an amount of 10 parts by mass relative to 100 parts by mass of the paper filter, also had stains observed, indicating that triacetin is prone to leak out during storage.

[0236] In contrast, no stains were observed in the filter samples A to C to which monoolein (MGO) was added, except for sample C to which MGO was added in an amount of 30 parts by mass. Regarding sample C, although some stains were observed and confirmed when stored for 1 month at 35°C and 60% RH, basically no stains were observed and confirmed when stored for 1 month at 22°C and 60% RH. Therefore, it can be seen that from the perspective of leakage, the amount of MGO added is preferably less than 30% relative to the mass of the filter material.

[0237] The phenol capture agent containing a semi-solid substance at room temperature, such as MGO used in the above test, can significantly inhibit its leakage from the filter. Therefore, the filter material loaded with the phenol capture agent containing a semi-solid substance at room temperature can keep the appearance of the fragrance inhalation article equipped with the filter material in a good state. In addition, compared with a solid substance at room temperature, a semi-solid substance such as MGO at room temperature has a large area in contact with phenol, so it is easy to realize a fragrance inhalation article with excellent phenol selection filtering ability.
