Description

[Technical Field]

[0001] The present invention relates to a sheet for a flavor inhalation article. [Background technology]

[0002] In conventional combustion-type smoking articles, it is known that activated carbon is packed into an acetate filter to remove components that impart undesirable flavors. For example, Patent Document 1 discloses a charcoal filter in which activated carbon is added to the surface of activated carbon-containing paper, and the paper is then folded and packed into a wrapper. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2011 / 118042 Summary of the Invention [Problem to be solved by the invention]

[0004] The invention disclosed in Patent Document 1 addresses the issue of limiting the amount of activated carbon that can be incorporated into paper because excessive amounts make the paper brittle. The gist of the invention is that the total amount of activated carbon can be increased by adding activated carbon both internally and externally. However, adding activated carbon externally requires a process such as creping the paper. This process increases the airflow resistance when used as a filter. The inventors then came up with the idea that if the amount of activated carbon added internally could be increased without making the sheet brittle, an ideal sheet for a flavor inhalation product could be obtained. In light of these circumstances, the present invention aims to provide a sheet for a flavor inhalation product that has excellent adsorption properties and ease of handling.

The diacid residue preferably contains a terephthalic acid, isophthalic acid, or phthalic acid residue, more preferably a terephthalic acid residue. Such a polyester can be represented by the following formula: In the formula, n represents the number of repetitions, and m represents an integer of 2 to 4. In particular, number Polyesters containing 2 to 4 alkylene glycol residues or isophthalic acid or phthalic acid residues do not have an excessively high degree of crystallinity, and therefore improve the adhesion between the polyester fibers and the adsorbent particles.

[0016] [ka]

[0017] (4) Other ingredients The sheet for flavor inhalation articles preferably contains a binder. The binder enhances adhesion between the fibers and between the fibers and the adsorbent. Known binders can be used, such as polyvinyl alcohol and vinyl acetate.

[0018] (5) Physical properties The sheet for flavor inhalation articles preferably has the following properties, and the blending amounts of the above components may be appropriately adjusted so as to achieve the properties. Tensile strength (ISO 1924-2): 5N / 15mm or more, preferably 5 to 30N / 15mm, more preferably 10 to 20N / 15mm Basis weight (ISO 536): 50~100g / m 2 , more preferably 70 to 90 g / m 2 Thickness: 100 to 300 μm, more preferably 150 to 250 μm Iodine adsorption capacity (JIS K 1474): 300 to 2000 mg / g, more preferably 500 to 1500 mg / g Air permeability: 0 to 30,000 CU, preferably 0 to 10,000 CU, more preferably 0 to 2,000 CU

[0020] Flavor inhalation sheet 1m 2 The effective surface area of ​​the adsorbent is preferably 5000 to 70,000 m 2 / m 2 The effective surface area is the total area of ​​the adsorbent exposed on the sheet surface. This range is based on the following:

[0021] In one embodiment, the area of ​​the adsorbent buried in the sheet is considered to be, on average, 30% to 50% of the surface area of ​​a single adsorbent. In other words, the exposed area of ​​the adsorbent is, on average, 50% to 70%. 2 / g, and the adsorbent content in the sheet is 10 g / m 2 If this is the case, the effective surface area when 50% of the area is exposed on average can be calculated as follows: 10g / m 2 ×1000m 2 / g×50%=5000m 2 / m 2 The surface area of ​​the adsorbent is 2000m 2 / g, the content is 50g / m 2 If this is the case, the effective surface area when 70% of the area is exposed on average can be calculated as follows: 50g / m 2 ×2000m 2 / g×70%=70,000m 2 / m 2

[0022] (6) Surface treatment of flavor inhalation product sheets In one embodiment, the sheet for flavor inhalation articles is not surface-treated. In another embodiment, the sheet for flavor inhalation articles is surface-treated. Examples of surface treatment include known treatments, but creping is preferred. Creping refers to a process in which a sheet is wrinkled in a crepe-like pattern using a doctor on a roll or the like. The crepe depth is preferably 0.1 to 0.5 μm.

[0023] 2. Manufacturing method of sheet for flavor inhalation article The above-mentioned components can be used to produce a sheet for a flavor inhalation article by a known method. For example, a paper sheet can be produced by preparing a slurry by mixing the above-mentioned components and then making a paper from the slurry. A cast sheet can be produced by casting the slurry on a substrate. A laminate sheet can be produced by rolling the slurry with a roller and then drying it. An extruded sheet can also be produced by extruding the slurry and then drying it.

[0024] 3.Applications (1) Rolling materials The sheet for flavor inhalation articles is useful as a wrapping material for flavor inhalation articles. Examples of wrapping materials include wrappers for wrapping one component and tipping paper for wrapping multiple components.

[0025] (2) Flavor inhalation article components The sheet for a flavor inhalation article is useful as a member for a flavor inhalation article, which includes a tip member, a flavor generating member including a flavor source, a support member, a cooling member, and a filter.

[0026] 1) Tip member The tipping member is a member disposed at the end opposite the mouth end of the flavor inhalation article. The sheet for the flavor inhalation article can be used as a filler or wrapper for the tipping member. Such a tipping member can remove moisture while the flavor inhalation article is being stored. For example, the tipping member can be manufactured by a manufacturing method including a step of filling a nonwoven fabric or cellulose acetate fiber, which is a filler, into the sheet for the flavor inhalation article, which is a wrapper.

[0027] 2) A flavor generating member containing a flavor source A flavor generating member containing a flavor source is a member that generates a flavor, such as a tobacco member. A sheet for a flavor inhalation article can be used as a wrapper for the flavor generating member. A flavor generating member containing a sheet for a flavor inhalation article has the effect of removing moisture while the flavor inhalation article is stored. A sheet for a flavor inhalation article can also be used as part of the filling material for the flavor generating member. Such a flavor generating member can remove moisture or components that impart an undesirable flavor while the flavor inhalation article is stored or during flavor inhalation. For example, a flavor generating member containing a flavor source can be produced by a manufacturing method comprising a step of filling a tobacco material, which is a filler, into a sheet for a flavor inhalation article, which is a wrapper. Alternatively, a flavor generating member containing a flavor source can be produced by a manufacturing method comprising a step of mixing sheet shreds or strand shreds obtained by cutting a sheet for a flavor inhalation article with a tobacco material to obtain a mixed shred, and a step of filling the mixed shreds into a wrapper.

[0028] 3) Support member The support member is a member for increasing the strength of the flavor inhalation article, and an example thereof is a center-hole filter. A sheet for flavor inhalation articles can be used as a material for constituting the center-hole filter. Such a support member can remove moisture or components that impart undesirable flavors while the flavor inhalation article is being stored or during flavor inhalation. For example, the support member can be manufactured by a manufacturing method including a step of forming a hollow tube from a sheet for flavor inhalation articles and filling the tube as a filler into the sheet for flavor inhalation articles, which is a wrapper. Furthermore, by making the hollow support member longer, it can also serve as a cooling member, as described below.

[0029] 4) Cooling material A cooling member is a member that cools a heated flavor. A sheet for a flavor inhalation article is useful as a material for constituting a cooling member. Such a cooling member can remove moisture or components that impart an undesirable flavor while the flavor inhalation article is being stored or during flavor inhalation. For example, a tube can be formed from the sheet for a flavor inhalation article and used as the cooling member. Ventilation may be provided as needed. As mentioned above, the cooling member can also serve as a support member.

[0030] 5) The filter The filter removes unwanted components as the aerosol passes through. The sheet for flavor inhalation articles is particularly useful as a filter sheet. The filter is preferably manufactured by a method including step 1 of preparing a sheet for flavor inhalation articles, and step 2 of preparing a filter including a cylindrical wrapper and the sheet disposed within the wrapper.

[0031] Step 1 is as described above. Step 2 can be carried out by a known method. For example, a filter can be produced by filling a cylindrical wrapper with a folded sheet for flavor suction articles or a cut sheet for flavor suction articles. Alternatively, a filter can be produced by folding a sheet for flavor suction articles into a cylindrical shape and wrapping the cylindrical shape with a wrapper. Before step 2, a step of subjecting the sheet for flavor suction articles to the above-mentioned surface treatment may be provided.

[0032] 4. Non-combustion heating type flavor inhalation product Flavor inhalation articles are broadly divided into combustion-type flavor inhalation articles (cigarettes) and non-combustion-heating-type flavor inhalation articles. Hereinafter, a non-combustion-heating-type flavor inhalation article will be described as an example. FIG. 1 shows one embodiment of a non-combustion-heating-type flavor inhalation article. In the figure, 10 is a non-combustion-heating-type flavor inhalation article, 1 is a tobacco member, 3 is a cooling member, 5 is a mouthpiece, 51 is a first filter, 52 is a second filter, and V is ventilation. The size of the non-combustion-heating-type flavor inhalation article is not limited. For example, its length may be about 50 to 80 mm, and its cross-sectional diameter may be about 5.5 to 7.5 mm.

[0035] The tobacco material may generate steam when heated. The heating temperature is not limited, but is about 30 to 400°C. To promote the generation of aerosol, an aerosol source such as glycerin, propylene glycol, or a polyol such as 1,3-butanediol may be added to the tobacco material. The amount of the aerosol source added is preferably 5 to 50% by weight, more preferably 10 to 30% by weight, based on the dry weight of the tobacco material. In addition, known flavors and the like may be added to the tobacco material. As mentioned above, the sheet for flavor inhalation articles can also be used as a wrapper for tobacco members.

[0036] (2) Cooling material The cooling member 3 is connected to the downstream side of the tobacco member 1. "Downstream" refers to the direction toward the mouth end. The cooling member 3 is a member for facilitating aerosolization by cooling flavor and aroma components and vapor generated in the tobacco member 1. The cooling member may be a hollow paper tube. The paper tube is preferably made of cardboard, which is more rigid than cigarette paper or tipping paper. As described above, the paper tube may also be made of a sheet for flavor inhalation articles. The paper tube may be provided with ventilation V (openings). It is preferable that multiple ventilations are provided along the circumference of the paper tube. The cooling member may also be filled with a gathered sheet to improve heat exchange efficiency. The dimensions of the cooling member are not limited, but the length is preferably 10 to 25 mm and the diameter is preferably 5.5 to 7.5 mm.

[0037] (3) Mouthpiece The mouthpiece is a component that constitutes the mouth end. In one embodiment, the mouthpiece 5 comprises a first filter 51 and a second filter 52. The first filter 51 may be a filter typically used in the field, and may be a solid acetate filter. The second filter 52 may comprise a wrapper and a sheet for flavor inhalation articles filled in the wrapper. The length of the second filter 52 is not particularly limited, but may be 5 to 20 mm, and preferably about 10 to 15 mm.

FIG. 7 shows an embodiment in which the support member 7 and the cooling member 3 in the embodiment of FIG. 6 are replaced with a support member 7 provided with ventilation. The dimensions in these figures are examples and may be adjusted as appropriate.

[0039] 5. Non-combustion heating type flavor inhalation system The combination of a non-combustion heating type flavor inhalation article and a heating unit is also referred to as a non-combustion heating type flavor inhalation system.

Flavor suction article. [Example]

[0043] [Example A1] A sheet containing moderately activated carbon as adsorbent particles, pulp, and polyester fibers was prepared and evaluated. The evaluation method is described below. The amount of activated carbon and the physical properties of the sheet are shown in Table 1. Next, a filter was produced by folding the sheet into a wrapper and filling it according to a standard method. The ridges formed by folding were approximately parallel to the longitudinal direction of the filter. The physical properties of the filter are also shown in Table 1. The sheet had excellent mechanical properties and was easy to handle. Furthermore, since the sheet contained a large amount of activated carbon, it provided a filter with excellent adsorption properties.

[0044] [Example A2] A sheet and a filter were produced and evaluated in the same manner as in Example A1, except that highly activated carbon was used as the adsorbent particles. The sheet had excellent mechanical properties and was easy to handle. Furthermore, the sheet contained a large amount of activated carbon, which provided a filter with excellent adsorption properties.

[0045] SEM photographs of the sheets produced in Examples A1 and A2 are shown in Figure 10. After platinum deposition on the sheets, the applied voltage was set to 10 kV and the images were observed at 800x and 10,000x magnifications. As shown in the figure, it was confirmed that the desired sheets were obtained.

[0046] [Table 1]

[0047] Table 1 also shows the physical properties of "Substrate A" and a filter manufactured from it in Comparative Example 1 of Patent Document 1. Substrate A is paper with activated carbon added inside, and does not contain polyester fiber.

[0048] [Examples B1 to B4] A sheet containing pulp, polyester fiber, activated carbon, and a binder was prepared. According to a standard method, the sheet was folded and packed into a wrapper to prepare a second filter as shown in Figure 1. The ridges formed by folding were approximately parallel to the longitudinal direction of the filter. The airflow resistance of the filter was measured using a filter quality measuring device (manufactured by SODIM, name: SODIMAX). Specifically, the sample was covered with air-impermeable rubber to prevent air from entering from the sides, and a 17.5 cm diameter piece of rubber was placed on one end of the sample. 3 The differential pressure (mmH2O) between both ends of the sample when aspirated at a flow rate of 1 / s was measured as the airflow resistance. Table 2 shows the physical properties of each filter.

[0049] Using this filter as a second filter, a non-combustion heating type suction article shown in Figure 1 was manufactured. The structure and size were as follows. Tobacco material / paper tube / second filter / first filter = 20 / 20 / 12 / 8 (mm)

[0050] The tobacco member end of the non-combustion heating flavor inhalation article was inserted into the heating device shown in FIG. 8. The heater temperature was set to 295°C, and the tobacco member was heated by the heater. A Cambridge filter (CM-133, manufactured by Borgwaldt KC Inc.) and an impinger containing DNPH (2,4-dinitrophenylhydrazine) solution were placed on the mouth end of the article, and the article was subjected to a smoking test using a smoking machine. Specifically, using an automatic smoking machine (LM-1, manufactured by Borgwaldt KC Inc.), the sample was automatically smoked under the following conditions: puff volume 27.5 ml / sec, puff time 2 sec / puff, puff frequency 2 puffs / min, 10 puffs.

[0051] Nicotine and glycerin were analyzed as follows. After the smoking test, the Cambridge filter was shaken in 10 mL of methanol (Wako Pure Chemical Industries, Ltd., special grade reagent) to obtain an analytical sample. 1 μL of the obtained analytical sample was collected in a microsyringe and analyzed by gas chromatography-mass spectrometry (Agilent GC-MSD, GC: 7890A, MS: 5975C). The results are shown in Table 2.

[0052] The carbonyl components, formaldehyde, acetaldehyde, and acrolein, were analyzed using the following method. After the smoking test, the Cambridge filter was immersed in impinger collection fluid and shaken, and the solids were then filtered through a membrane filter. A predetermined amount of the filtrate was then added to Trizma base solution and shaken to terminate the derivatization reaction. The solution was then filtered through a membrane filter again and subjected to HPLC-DAD analysis for the carbonyl components. The carbonyl component analysis method was based on the disclosures in WO2004 / 026054 and CORESTA Recommended Method No. 96 - Determination of Formaldehyde and Acetaldehyde in E-Vapor Product Aerosol, February 2021. The results are shown in Table 3. The relationship between Ch / PD and formaldehyde content is shown in Figure 9.

[0053] [Comparative examples B1~B2] A center-hole filter and a paper filter were prepared. The physical properties of the filters are shown in Table 2. Non-combustion heating-type flavor inhalation articles were prepared in the same manner as in Example B1, except that the center-hole filter and the paper filter were used instead of the second filter 52, and the particulate matter in the tobacco smoke was quantified. The results are shown in Table 3.

[0054] [Table 2]

[0055] [Table 3]

[0056] It is clear that the filter produced in Example B is effective in removing components that have an undesirable effect on the flavor and taste of tobacco, particularly formaldehyde, acetaldehyde, and acrolein, which are difficult to remove with conventional filters. [Explanation of symbols]
