Description

[Technical field]

[0001] The present invention relates to an electronic cigarette cartridge, and more particularly to an electronic cigarette cartridge for smoking by volatilizing internal components. [Background technology]

[0002] Recently, due to the impact of the smoking ban on tobacco, smoking devices that do not use flames (electronic cigarette products) are becoming more widespread, replacing cigarettes in which tobacco leaves are lit and smoked (see Patent Documents 1 and 2, etc.). The electronic cigarette products listed in the patent documents mimic the structure of existing paper cigarettes, and are in the form of a rod in which chopped tobacco leaves and a filter are wrapped in paper, and are also called cartridges, etc.

[0003] The cartridge containing the tobacco leaves is heated, and the vaporized tobacco components are inhaled, allowing the user to enjoy the flavor of tobacco. In e-cigarette products, the cartridge is inserted into a dedicated heating device, and the tobacco leaf components are vaporized by electric heating to generate an aerosol. The user inhales the generated aerosol to smoke. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2015-519915 [Patent Document 2] International Publication WO2016 / 162934 Summary of the Invention [Problem to be solved by the invention]

[0005] The overall shape of the cartridge depends on the wrapping paper. Therefore, the wrapping paper is required to have the strength necessary to maintain the shape. Furthermore, the wrapping paper also has the function of contacting the user's mouth, fitting to a dedicated heating device, and holding the tobacco leaves inside. Therefore, the inventors have conducted extensive research into the physical properties of the wrapping paper and have found physical properties suitable for wrapping paper in electronic cigarette cartridges.

[0006] The present invention has been made in consideration of the above points, and provides an electronic cigarette cartridge that has wrapping paper characteristics that are suitable for contacting the user's mouth, for fitting to a dedicated heating device, and for holding tobacco leaves and the like inside. [Means for solving the problem]

[0007] That is, the electronic cigarette cartridge comprises a flavor section made of a tobacco plant or a non-tobacco plant, a filter section provided on the rear end side of the flavor section, and a wrapping paper member covering at least the flavor section with its inner surface, and is characterized in that, when measured in accordance with JIS B 0601 (2013), the arithmetic mean surface roughness (Rai) of the inner surface of the wrapping paper member is 1 μm or more, and the average maximum roughness (Rzi) of the inner surface is 15 μm or more, and the arithmetic mean surface roughness (Rao) of the outer surface opposite the inner surface of the wrapping paper member is 2 to 20 μm, and the average maximum roughness (Rzo) of the outer surface is 230 μm or less. Effect of the Invention

[0008] According to the electronic cigarette cartridge of the present invention, by defining the characteristics of the rolling paper of the electronic cigarette cartridge in terms of the physical properties of surface roughness, the rolling paper can be made to be excellent in terms of contact with the user's mouth, suitability for attachment to a dedicated heating device, and ability to hold tobacco leaves and the like inside, thereby forming an electronic cigarette cartridge that feels good to the touch.

[0010] 1 is a cross-sectional view of an electronic cigarette cartridge 1 of a first embodiment. The electronic cigarette cartridge 1 includes a flavor section 11 and a filter section 14, and the flavor section 11 and the filter section 14 are covered with a wrapping paper member 20. As shown in the figure, the filter section 14 is provided in order to be disposed on the rear end side 11e of the flavor section 11. The electronic cigarette cartridge 1 of the first embodiment further includes a support member 12 between the flavor section 11 and the filter section 14. In the figure, reference symbol 20i denotes an inner surface of the wrapping paper member 20, and reference symbol 20o denotes an outer surface of the wrapping paper member 20.

[0011] The cross-sectional view of Fig. 2 shows the electronic cigarette cartridge 1 in use. In the electronic cigarette cartridge 1, the filter part 14 side is held in the mouth of a user (smoker). The flavor part 11 side, which is opposite the filter part 14, is inserted into the inside of an insertion opening 31 of a heating member 30. A heating needle 32 is provided in the insertion opening 31. When the electronic cigarette cartridge 1 is inserted, the heating needle 32 pierces the flavor part 11. Electricity is applied to the heating needle 32 by operating the heating member 30 (not shown), and the heating needle 32 generates heat by resistance heating.

[0012] The flavor section 11 is heated by thermal conduction from the heating needle 32, and an aerosol is generated from the flavor section 11. The user then inhales the aerosol generated by the heating from the mouth through the filter section 14. In this way, the user can enjoy smoking. The support member 12 is provided for the purpose of lowering the temperature of the aerosol generated from the flavor section 11.

[0013] The flavor portion 11 is made of a tobacco plant or a non-tobacco plant. The tobacco plant is Nicotiana tabacum, which is used in conventional cigarettes. Tobacco contains nicotine. Therefore, when an electronic cigarette cartridge that does not contain nicotine is desired, a non-tobacco plant is used instead of the tobacco plant.

[0014] The non-tobacco plant is not limited as long as it is a plant other than tobacco. Examples of parts of the plant that can be used include roots (scale roots (bulbs), tuberous roots (tubers), bulbs, etc.), stems, tubers, bark (stem bark, bark, etc.), leaves, flowers (petals, pistils, stamens, etc.), tree trunks, branches, etc.

[0030] Extracts of the above-mentioned non-tobacco plants, so-called extracts, can also be used. The extracts may be in the form of liquid, starch syrup, powder, granules, solution, etc.

[0031] Other examples of binders that can be used include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, and dimethyl tetradecanedione, with glycerin and propylene glycol being particularly preferred if necessary.

[0032] Flavor additives that add flavor are also preferably used. Examples of flavor additives include mint, cocoa, coffee, and black tea extracts. Furthermore, food preservatives may be added, such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate, if necessary.

[0033] The filter section 14 is made of the same filter material as that used in known cigarettes. Specifically, it is made of a resin such as cellulose acetate. The aerosol generated by heating the flavor section 11 passes through the filter section 14 and is inhaled by the user. The filter section 14 appropriately adsorbs volatile components, smoke, etc. in the generated aerosol. Therefore, the stimulation received by the user when inhaling the aerosol is reduced, allowing the user to enjoy smoking.

[0034] Furthermore, in the electronic cigarette cartridge 1 of the first embodiment, a support member 12 is provided for the purpose of lowering the temperature of the aerosol generated from the flavor section 11. By providing a gap between the flavor section 11 and the filter section 14, the temperature of the aerosol is appropriately lowered, and high-temperature aerosol is prevented from being inhaled by the user. The support member 12 can be omitted depending on the heating temperature of the flavor section 11. The support member 12 has an appropriate shape obtained by cutting out a part of a cylinder, as disclosed in, for example, Japanese Patent No. 6280287. The material may be any appropriate material, and silicone resin is preferably used in terms of temperature resistance.

[0035] A wrapping paper member 20 is used to maintain the shape of the electronic cigarette cartridge 1. The wrapping paper member 20 is made of paper and therefore has hygroscopic properties, can suppress the absorption of moisture by the flavor portion 11, and is inexpensive. This wrapping paper member 20 covers at least the flavor portion 11. In the first embodiment of FIG. 1, the flavor portion 11 and the filter portion 14 are in contact with and covered by the inner surface 20i of the wrapping paper member 20. The surface of the wrapping paper member 20 opposite to the inner surface 20i is the outer surface 20o. The wrapping paper member 20 contacts the lips when held in the user's mouth. In addition, the wrapping paper member 20 also contacts the inner side of the insertion port 31 when inserted into the heating member 30. In this case, the wrapping paper member 20 is required to have a touch when in contact with the lips, good fixation to the heating member 30, and good retention of the flavor portion 11 and the filter portion 14. Various indices of surface roughness are used to define this.

[0036] Specifically, the surface properties of the wrapper member 20 are regulated by various surface roughness-related indices conforming to JIS B 0601 (2013). The arithmetic mean surface roughness (Rai) of the inner surface 20i of the wrapper member 20 is 1 μm or more. The average maximum roughness (Rzi) of the inner surface 20i of the wrapper member 20 is 15 μm or more, preferably 16 μm or more.

[0037] The arithmetic mean surface roughness (Rao) of the outer surface 20o of the paper wrapper member 20, which is the opposite surface to the inner surface 20i, is 2 to 20 μm, preferably 2.5 to 17 μm, and more preferably 2.7 to 15 μm. The average maximum roughness (Rzo) of the outer surface 20o of the paper wrapper member 20 is 230 μm or less, and preferably 15 to 230 μm.

[0038] Furthermore, the kurtosis (Rkui) of the inner surface 20i of the paper wrapper 20 is from 1 to 15, preferably from 2 to 12, and more preferably from 2.5 to 11. The kurtosis (Rkuo) of the outer surface 20o of the paper wrapper 20 is from 2 to 18, preferably from 2.5 to 15, and more preferably from 2.7 to 14.5.

[0039] In addition, the average length of the roughness curved elements (Rsmi) of the inner surface 20i of the paper wrapper 20 is 150 to 1300, preferably 190 to 1100, and more preferably 195 to 1100. The average length of the roughness curved elements (Rsmo) of the outer surface 20o of the paper wrapper 20 is 150 to 3500, preferably 160 to 3300, and more preferably 170 to 3100.

[0040] The skewness (Rski) of the inner surface 20i of the paper wrapper 20 is −2 to 6, preferably −0.9 to 5.5, and more preferably −0.9 to 5. The skewness (Rsko) of the outer surface 20o of the paper wrapper 20 is −2.5 to 2.5, preferably −2 to 2, and more preferably −1.9 to 1.9.

[0041] Here, the arithmetic mean surface roughness: Ra indicates the average value of height difference from the average surface. The average maximum roughness: Rz indicates the peak value of the surface height. The kurtosis: Rku indicates the sharpness of the surface. The average length of the roughness curve element: Rsm is an indicator of the lateral size rather than the height of the surface irregularities. The skewness: Rsk indicates the symmetry of the peaks and valleys when the average line is taken as the center.

[0042] The combination of these indices defines the gloss of the appearance of the outer surface 20o of the electronic cigarette cartridge 1, the feel and texture when held in the hand, and the feel when held in the mouth. If the roughness (unevenness) of the outer surface is too small, the friction when handling the electronic cigarette cartridge is low and it is easy to slip off from the fingers. In addition, although the gloss increases, it is reminiscent of the texture of a resin film and loses the texture of the original cigarette. Conversely, if the surface roughness increases, the gloss is lost overall and the appearance becomes poor. In addition, when it comes into contact with the lips, the roughness increases and the feel becomes uncomfortable.

[0043] Next, the roughness (unevenness) of the inner surface 20i of the electronic cigarette cartridge 1 is specified from the viewpoint of holding the flavor section 11 and the filter section 14 and preventing them from easily coming off from the fixed portions. If the inner surface is too rough (uneven), friction will not occur and the holding force of each component will be weakened. If the inner surface is too rough (uneven), the number of contact points with each component will also be reduced and the holding force will not be maintained. From the above viewpoints, the ranges of the individual surface roughness indexes of the inner surface 20i and the outer surface 20o of the wrapping paper member 20 are specified.

[0044] As shown in the exploded cross-sectional schematic diagram of Fig. 3, the wrapping paper member 20 includes a first wrapping paper member 21 that contacts and covers the flavor portion 11 with a first inner surface 21i. The wrapping paper member 20 includes a second wrapping paper member 24 that contacts and covers the filter portion 14 with a second inner surface 24i. In the electronic cigarette cartridge 1 of the first embodiment shown in the figures, the wrapping paper member itself is changed to cover each component. Therefore, the surface roughness index is specified in more detail depending on the component and the portion.

[0045] The first wrapping paper member 21 has an inner side, which is a first inner surface 21i, which is in contact with the flavor portion 11, and an outer side, which is a first outer surface 21o. The first outer surface 21o is in contact with the third wrapping paper member 23 and the inner side of the insertion opening 31 of the heating member 30.

[0046] The arithmetic mean surface roughness (Rai1) of the first inner surface 21i of the first wrapping paper member 21 is 1 to 15 μm, preferably 1.5 to 13 μm. The average maximum roughness (Rzi1) of the first inner surface 21i of the first wrapping paper member 21 is 100 μm or less, preferably 20 to 100 μm or more.

[0047] The arithmetic mean surface roughness (Rao1) of the first outer surface 21o, which is the surface opposite to the first inner surface 21i of the first wrapping paper member 21, is 2 to 20 μm, preferably 2.5 to 18 μm, and more preferably 3 to 17 μm. The average maximum roughness (Rzo1) of the first outer surface 21o of the first wrapping paper member 21 is 100 μm or less, and preferably 20 to 100 μm.

[0048] Furthermore, the kurtosis (Rkui1) of the first inner surface 21i of the first wrapping paper member 21 is 2.5 to 11. The kurtosis (Rkuo1) of the first outer surface 21o of the first wrapping paper member 21 is 2 to 6, preferably 2.5 to 6, and more preferably 2.6 to 6.

[0049] In addition, the average length (Rsmi1) of the roughness curve elements of the first inner surface 21i of the first wrapping paper member 21 is 150 to 1000, preferably 170 to 1000, and more preferably 190 to 1000. The average length (Rsmo1) of the roughness curve elements of the first outer surface 21o of the first wrapping paper member 21 is 150 to 1400, preferably 160 to 1300, and more preferably 170 to 1200.

[0050] The skewness (Rski1) of the first inner surface 21i of the first wrapping paper member 21 is -1.25 to 1.25, preferably -1.2 to 1.2, and more preferably -1.15 to 1.15. The skewness (Rsko1) of the first outer surface 21o of the first wrapping paper member 21 is -1.25 to 1.25, preferably -1.2 to 1.2, and more preferably -1.15 to 1.15.

[0051] The second wrapper member 24 has an inner surface which is a second inner surface 24i and which is in contact with the filter portion 14, and an outer surface which is a second outer surface 24o. The second outer surface 24o comes into direct contact with the user's lips.

[0052] The arithmetic mean surface roughness (Rai2) of the second inner surface 24i of the second wrapping paper member 24 is 3 to 15 μm, preferably 4 to 13 μm, and more preferably 5 to 11 μm. The average maximum roughness (Rzi2) of the second inner surface 24i of the second wrapping paper member 24 is 100 μm or less, and preferably 20 to 80 μm or more.

[0053] The arithmetic mean surface roughness (Rao2) of the fourth outer surface 24o opposite the second inner surface 24i of the second wrapper member 24 is 2 to 20 μm, preferably 2.5 to 18 μm, and more preferably 2.7 to 17 μm. The average maximum roughness (Rzo2) of the fourth outer surface 24o opposite the second inner surface 24i of the second wrapper member 24 is 230 μm or less, and preferably 15 to 230 μm.

[0054] Furthermore, the kurtosis (Rkui2) of the second inner surface 24i of the second wrapping member 24 is from 2 to 10. The kurtosis (Rkuo2) of the second outer surface 24o of the second wrapping member 24 is from 2 to 10, preferably from 2.3 to 10, and more preferably from 2.5 to 10.

[0055] In addition, the average length of the roughness curve elements (Rsmi2) of the second inner surface 24i of the second wrapping member 24 is 180 to 1300, preferably 200 to 1200, and more preferably 220 to 1100. The average length of the roughness curve elements (Rsmo2) of the second outer surface 24o of the second wrapping member 24 is 300 to 3500, preferably 330 to 3300, and more preferably 350 to 3100.

[0056] The skewness (Rski2) of the second inner surface 24i of the second wrapping member 24 is -1.2 to 6, preferably -1 to 5, and more preferably -0.9 to 4.7. The skewness (Rsko2) of the second outer surface 24o of the second wrapping member 24 is -2.5 to 2.5, preferably -2 to 2, and more preferably -1.9 to 1.9.

[0057] As shown in Fig. 3 and other figures, the first wrapping paper member 21 directly contacts and holds the flavor portion 11. Therefore, the first inner surface 21i side needs to have a surface roughness that generates appropriate friction. Furthermore, the first outer surface 21o side needs to have a surface roughness that takes into account contact with the insertion opening 31 of the heating member 30 and contact with the third wrapping paper member 23. Therefore, the above-mentioned ranges are specified.

[0058] As shown in Fig. 3 and other figures, the second wrapping paper member 24 also directly contacts and holds the filter portion 14. It also contacts the third wrapping paper member 23. Therefore, the second inner surface 24i side needs to have a surface roughness that generates an appropriate degree of friction. Furthermore, since it comes into direct contact with the user's lips, it needs to have a surface roughness that does not cause any discomfort compared to existing cigarettes. For this reason, the above-mentioned ranges are specified.

[0059] The wrapping paper member 20, the first wrapping paper member 21, and the second wrapping paper member 24 of the electronic cigarette cartridge 1 are further regulated by the physical property of the thickness of the paper. The thickness of the wrapping paper member 20 is 0.02 mm or more, preferably 0.02 to 0.2 mm. In particular, the thickness of the first wrapping paper member 21 is 0.02 mm or more, preferably 0.02 to 0.2 mm, and the thickness of the second wrapping paper member 24 is 0.05 mm or more, preferably 0.05 to 0.2 mm. As for the second wrapping paper member 24, the saliva of the user penetrates into the second wrapping paper member 24 through contact with the lips of the user. Therefore, the number of turns of the paper is increased to increase the strength. Taking this into account, a somewhat thinner paper is used.

[0060] The wrapping paper member 20, the first wrapping paper member 21, and the second wrapping paper member 24 of the electronic cigarette cartridge 1 are considered to have the physical property of paper air permeability. This is because an appropriate amount of air is required when a user inhales tobacco aerosol. The air permeability of the wrapping paper member 20 is 2 kPa or more. In particular, the air permeability of the first wrapping paper member 21 is 2 kPa or more, and the air permeability of the second wrapping paper member 24 is 30 kPa or more. The reason why the air permeability is reduced in comparison with the second wrapping paper member 24 and the first wrapping paper member 21 is to prevent the leakage of intake air from around the filter portion 14.

[0061] The physical property of the wet-dry tensile strength of the paper (hereinafter referred to as tensile strength) is added to the wrapping paper member 20, the first wrapping paper member 21, and the second wrapping paper member 24 of the electronic cigarette cartridge 1. The tensile strength of the wrapping paper member 20 is 0.3 N / mm or more, preferably 0.4 N / mm or more. In particular, the tensile strength of the first wrapping paper member 21 is 0.3 N / mm or more, preferably 0.4 N / mm or more, and the tensile strength of the second wrapping paper member 24 is 0.8 N / mm or more, preferably 0.9 N / mm or more, more preferably 1 N / mm or more. The reason why the tensile strength of the second wrapping paper member 24 is higher than that of the first wrapping paper member 21 is that when a user holds the electronic cigarette cartridge 1 in his mouth, saliva penetrates the second wrapping paper member 24 side. Therefore, the strength is ensured even in a wetter state.

[0062] Next, the electronic cigarette cartridge 1 is heated by the heating member 30 (see FIG. 2), and the aerosol generated from the flavor section 11 of the electronic cigarette cartridge 1 is summarized as follows.

[0063] Regardless of whether it is tobacco material or non-tobacco material, the material that is the source of the aroma is called the "aroma source material," the part in the aroma cartridge that is filled with this as the object to be heated to generate the "aerosol for aroma" is called the "aroma generating body," the thing that is manufactured into a specific state (including solid, liquid, and gel) based on the "aroma source material" to generate the aroma and that is placed in the main body of the "aroma generating body" is called the "aroma source," and the device that is equipped with a heating element and heats the aroma generating body in the aroma cartridge is called the "aroma device." These also apply to those that use non-tobacco materials that do not contain tobacco components.

[0064] "Aroma" means "a pleasant smell" and includes the smell that wafts from the material itself (fragrance), the smell that fills the air when heated (aroma), and the smell that wafts into the mouth when inhaled (flavor).

[0065] "Smoking" generally means smoking tobacco, but here it simply means "enjoying smoke," "tasting smoke," or "enjoying smoke," and the source of smoke is not limited to tobacco, but also applies to non-tobacco materials. In addition, "smoke" here also includes "something that looks like smoke" or "something that is smoke-like," such as droplets dispersed in the air, such as aerosols.

[0066] In the field of electronic cigarettes, unlike conventional flame-heated cigarettes, the heating temperature and range can be freely controlled, allowing users to smoke flavors that are the same as or different from cigarettes.

[0067] Therefore, by defining the material used in the aroma source material (flavor portion 11 in FIG. 1) of the electronic cigarette cartridge and further the components of the resulting aerosol, a new smoking device, a filling material in the electronic cigarette cartridge, is provided.

[0068] That is, (1) a filler for a heated electronic cigarette, in which the peaks of an ion gas chromatogram containing non-tobacco plant components for forming an aerosol and aerosol former components in the components constituting the aerosol former are separated at a column temperature in the range of 200 to 400° C. and are shown on an ion detector of a gas chromatograph mass spectrometer. Details of the ion gas chromatogram will be mentioned in the Examples.

[0069] (2) The non-tobacco plants that form the aerosol include (i) at least one of Chinese tea, black tea, rose, sweet osmanthus, lavender, and saffron flowers as materials that emit a fragrance, defined as an aroma that wafts from the plant itself; (ii) at least one of the rhizomes of shallots, garlic, onion, and konjac as materials that emit an aroma, defined as an aroma that wafts through space when the aerosol-forming body is heated; and (iii) at least one of the above-ground stems and leaves of quince, plants of the genus Citrus in the family Rutaceae, grapes, peppermint plants in the genus Mentha in the family Lamiaceae, spearmint plants in the genus Mentha in the family Lamiaceae, and catnip, common mentha, brugmansia, and willow mentha, as materials that emit a flavor, defined as an aroma that wafts through the mouth when the aerosol-forming body is heated and inhaled together with the aerosol.

[0070] The non-tobacco plant is selected from the plants described above.

[0071] (3) A filler for a heated electronic cigarette that uses at least one of propylene glycol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, or glycerin as an aerosol former material.

[0072] The purpose of the aerosol former is that it is preferable for it to have a suitable viscosity in order to become an aerosol after heating. Also, the aerosol former has a hydrophobic site, which assists in dissolving hydrophobic components.

[0073] The mass balance of each component is within a range that provides a good taste when a user uses the electronic cigarette cartridge to smoke, and of course, the components can be adjusted according to the user's preference for tobacco or non-tobacco flavors.

[0074] Next, the vaporized components measured by gas chromatography mass spectrometry when the electronic cigarette cartridge is used are a heated electronic cigarette filler containing, in the entire vaporized components, the following mass proportions: aerosol former: 30 to 70 mass%, paraffinic hydrocarbons: 10 mass% or less, carbon dioxide: 5 mass% or less, and water: 1 to 5 mass%.

[0075] The aerosol formers are the components listed in (3) Aerosol formers above. Paraffinic hydrocarbons are mainly compounds of carbon and hydrogen. Water is derived exclusively from tobacco plants or non-tobacco plants contained in the filler (flavoring portion 11 in FIG. 1). Carbon dioxide is derived from the generation of tobacco plants or non-tobacco plants when they are burned by heating.

[0076] Furthermore, the vaporized components of the filling material for a heated electronic cigarette contain, as a whole of the vaporized components, 0.01 to 1 mass% of limonene, 0.01 to 1 mass% of cyclotene, 0.1 to 15 mass% of menthol, and 0.01 to 1.5 mass% of neophytadiene.

[0077] The taste of a cigarette is mainly determined by the amount of these components.

[0078] In addition, the filling material for a heated electronic cigarette contains, as a vaporized component, nicotine in an amount of 15 mass% or less in the entire vaporized component.

[0079] Nicotine comes from the tobacco plant, which is why it tastes similar to conventional cigarettes.

[0080] The filling material for a heated electronic cigarette contains, as a vaporized component, 1 to 8 mass % of caffeine in the entire vaporized component.

[0081] Caffeine comes from non-tobacco plants and is primarily found in tea fillings.

[0082] In addition, as a filling material for a heated electronic cigarette, one or more of the following may be selected: cacao beans, guarana, coffee beans, mate tea, green tea, gyokuro, sencha, matcha, roasted green tea, bancha, kettle tea, brown rice tea, oolong tea, Chinese tea, black tea, and cola nuts.

[0083] By using the listed materials as a filler, it is possible to impart a variety of flavors to the heated electronic cigarette. Note that the present invention is not limited to the heated electronic cigarette, and may be used for a tobacco-like smoking device that does not use tobacco plants. EXAMPLES

[0084] [Measurement of various indexes of surface roughness] Nine types of paper for use in e-cigarette cartridges were prepared and measured in accordance with JIS B 0601 (2013). Measurements were performed at five points (n=5) for each type of part.

[0090] The various physical properties related to the surface roughness of the paper used in the electronic cigarette cartridge were obtained. Based on these, the preferable ranges of the various physical properties related to the surface roughness as described above were obtained.

[0091] [Measurement of Paper Thickness] The thickness of each part of the paper used in the electronic cigarette cartridge was measured under the same conditions as the measurement of the arithmetic mean surface roughness for the same number of samples, as shown in Table 1. There is no distinction between the outer and inner surfaces.

[0092] [Table 1]

[0093] [Measurement of air permeability] The measurement equipment used was a texture analyzer (TA.XTplus, Stable Micro System) and an attached dedicated cylindrical probe (diameter 35 mm). The same number of samples as those used for the measurement of arithmetic mean surface roughness were used.

[0094] (1) To prepare the specimen, a paper sample was punched out using a punch with an inner diameter of 13 mm to prepare the specimen. (2) A stainless steel membrane filter holder (Swinny Filter Holder 13 mm; filter size: φ13 mm, Merck) was connected to a plastic syringe (10 mL Terumo syringe) using a Luer lock, and the connection was fixed with epoxy adhesive. A gasket (outer diameter 13 mm, inner diameter 10 mm, thickness 0.1 mm) was added to this. (3) For the breathability test (measurement of air permeability), the crosshead of the texture analyzer was moved at a speed of 5 mm / s to push the plunger in. The test was stopped just before the plunger rubber reached the tip of the syringe barrel, and a load-strain curve was obtained (n=5). In addition, a blank test was conducted (n=5) in which the sample paper was not sandwiched, and the difference in load with and without the sample paper was calculated. In the measurement of air permeability, the smaller the value, the higher the breathability.

[0095] The results of the breathability test (average of 5 points) are shown in Table 1. There is no distinction between the outer and inner surfaces.

[0096] [Measurement of wet and dry tensile strength] The measurement equipment used was a texture analyzer (TA.XTplus, Stable Micro System) and the attached tensile grip. Sandpaper was attached to a total of four surfaces of the grip to prevent slipping. The same number of samples as the measurement of arithmetic mean surface roughness were used.

[0097] (1) To prepare the sample, 0.5 μL of a 1:1 mixture (by weight) of deionized water and glycerin was dropped onto the center of a paper specimen cut into a rectangle (width 7 mm, length 15 mm or more) using a micropipette. After visually confirming that the spot had almost completely stopped spreading due to absorption of the solution, the spot diameter in the width direction of the specimen was measured with a caliper and the specimen was immediately subjected to the tensile test described below.

[0098] (2) The tensile test conditions were as follows: Gap: 10mm Crosshead speed: 8mm / min Data acquisition frequency: 10 points / s Crosshead travel distance: 3mm (3) When analyzing the data, the maximum load (Fmax [N]) that appeared before breakage was taken as the tensile strength, referring to the method described in Japanese Patent No. 6572318. Fmax was divided by the dry part width [N], which was calculated by subtracting the spot diameter from the width of the paper sample, to obtain the maximum load [N / mm] per unit dry part width.

[0099] The results of the wet and dry tensile strength (five-point average) are shown in Table 1. There is no distinction between the outer and inner surfaces.

[0100] [Component analysis] The volatile components generated in the filling (flavoring part) of an electronic cigarette cartridge during use were identified using gas chromatography mass spectrometry. 0.3 mg of the flavoring part (filling) of an electronic cigarette cartridge was sampled and subjected to a gas chromatography mass spectrometry device. The flavoring part (filling) of the electronic cigarette cartridge used for the measurement was an item made using tea leaves, a non-tobacco plant.

[0101] Gas chromatography mass spectrometry: Agilent Technologies, 7890A / 5975C Sample introduction device: Frontier Labs, PY-3030D Carrier gas: He Column: ZB-XLB-HT Inferno (inner diameter 0.25 mm, length 30 m, film thickness 0.25 μm) Thermal desorption temperature: The temperature was increased from 200°C to 400°C at a rate of 30°C / min. Gas chromatograph inlet temperature: 330℃ Split ratio: "1:30"

[0102] The mass spectrometry conditions were as follows: Ionization method: Electron ionization method Mass spectrometer interface temperature: 280℃ Scan range: m / z 15-600

[0103] Gas chromatography analysis showed that nicotine was not present in the identified components, and some contained caffeine instead. This is because tobacco plants were not used. In addition, many components that give users a refreshing feeling when smoking, such as aroma, were also detected. In addition, it was found that the product has a good taste when smoking without using tobacco plants.

[0104] When the first wrapping paper member 21 and the second wrapping paper member 24 are provided, the second inner surface of the second wrapping paper member 24 can be disposed so as to cover a part of the first outer surface of the first wrapping paper member 21. The first wrapping paper member 21 covers at least the flavor portion 11, and the second wrapping paper member 24 covers at least the filter portion 14. A support member 12, a cooling member, etc. may or may not be provided between the flavor portion 11 and the filter portion 14. In addition, there may be a space between the flavor portion 11 and the filter portion 14.

[0105] In this case, the second outer surface of the second wrapping paper member 24 may be configured to have a kurtosis (Rkuo2) of 3 or more and a skewness (Rsko2) of the second outer surface of the second wrapping paper member 24 less than 0. According to this configuration, the second outer surface of the second wrapping paper member 24 that comes into contact with the user's hand has a relatively large variation in surface irregularities, and has more concaves than convexities, making it pleasant to the touch, and also makes it easier to insert the electronic cigarette cartridge 1 into the heating member 30 by generating a certain amount of friction.

[0106] Next, an electronic cigarette cartridge 50 according to a second embodiment will be described. Fig. 4 is an exploded perspective view of the electronic cigarette cartridge 50 according to the second embodiment. The electronic cigarette cartridge according to this embodiment has a hard, thick, cylindrical wrapping paper member 70, and is formed by inserting a flavor section 60 and a filter section 64 into the cylindrical wrapping paper member 70.

[0107] In this embodiment, the wrapping paper member 70 covers from one end of the flavor portion 60 to the other end that becomes the mouth of the filter portion 64. The thickness of the wrapping paper member 70 is 0.1 mm to 0.5 mm, preferably 0.2 mm to 0.4 mm. In this case, the wrapping paper member 70 is thick and hard at the mouth portion where the user's lips come into contact, which is likely to cause discomfort. In addition, since the wrapping paper member 70 is difficult to deform, if the flavor portion 60 and the filter portion 64 held inside are not sufficiently in close contact with the wrapping paper member 70, they may fall off when the user takes out the electronic cigarette cartridge 50 and inserts it into the heating member 30. For this reason, it is required that the outer surface of the wrapping paper member 70 is less uncomfortable when the user holds it in his / her mouth, and that the inner surface of the wrapping paper member 70 has a good holding force for the flavor portion 60 and the filter portion 64.

[0108] The physical properties of the wrapping paper member 70 having such characteristics are preferably within the following ranges. The arithmetic mean surface roughness (Rai) of the inner surface of the wrapping paper member 70 is 5 to 10 μm, and the arithmetic mean surface roughness (Rao) of the outer surface of the wrapping paper member 70 is 6 to 15 μm. The average maximum roughness (Rzi) of the inner surface of the wrapping paper member 70 is 25 to 40 μm, and the average maximum roughness (Rzo) of the outer surface of the wrapping paper member 70 is 40 to 60 μm. The kurtosis (Rkui) of the inner surface of the wrapping paper member 70 is 3 to 5, and the kurtosis (Rkuo) of the outer surface of the wrapping paper member 70 is 3 to 5. By satisfying at least a part of these physical property ranges, the user feels less uncomfortable when holding it in his / her mouth, and the retention force of the flavor portion 60 and the filter portion 64 can be improved. These physical property ranges can also be applied to the wrapping paper member 20 of the first embodiment, and the same effects can be achieved.

[0109] The components housed inside the wrapping paper member 70 are not limited to the flavor section 60 and the filter section 64. Fig. 5 shows a modified example of the electronic cigarette cartridge 50. Fig. 5(a) shows the electronic cigarette cartridge 50 shown in Fig. 4, in which the flavor section 60 and the filter section 64 are arranged adjacent to each other inside the wrapping paper member 70.

[0110] In the electronic cigarette cartridge 50 of FIG. 5(b), the support member 62 is disposed adjacent to the flavor portion 60, and a space portion 69 is formed between the support member 62 and the filter portion 64. When the heating needle 32 is inserted into the flavor portion 60, the flavor portion 60 is pushed toward the filter portion 64, and the support member 62 supports it. If the support member 62 is adjacent to the filter portion 64, the support member 62 is supported by the filter portion 64, but if the support member 62 is adjacent to the space portion 69, the flavor portion 60 needs to be supported by the frictional force of the support member 62 with the wrapping paper member 70. In this case, by setting the wrapping paper member 70 to have the above-mentioned physical property range, the support member 62 is reliably held by the wrapping paper member 70, and the flavor portion 60 and the support member 62 can be prevented from being pushed into the space portion 69.

[0111] 5(c), the electronic cigarette cartridge 50 has a support member 62 disposed adjacent to the flavor section 60, a cooling member 65 disposed adjacent to the support member 62, a ball 66 containing a flavoring disposed adjacent to the cooling member 65, and a filter section 64 disposed adjacent to the ball 66. Even with this configuration, by making the wrapping paper member 70 have the above-mentioned physical properties, the user feels less uncomfortable when holding it in their mouth, and the retention force of the flavor section 60 and the filter section 64 can be improved.
