Summary of the Invention

[0004] In recent years, non-combustion heating type fragrance attracting articles that do not involve combustion are very useful from the viewpoint of reducing odors and are being rapidly accepted in the tobacco market. On the other hand, in non-combustion heating type fragrance attracting articles, the heating temperature is significantly lower (30°C to 400°C) compared to the temperature during the combustion of traditional cigarette paper (700°C to 900°C). For this reason, simply containing the same amount of fragrance in the tobacco shreds as in traditional cigarette paper results in a problem that the intensity of the fragrance felt by the user is not sufficient. Therefore, in this new type of fragrance attracting article (non-combustion heating type fragrance attracting article), in order to obtain a refreshing feeling (smoking taste) equivalent to that of traditional cigarette paper, it is necessary to contain a larger amount of fragrance in the tobacco shreds compared to traditional cigarette paper. Therefore, in non-combustion heating type fragrance attracting articles, compared to traditional cigarette paper, bleeding caused by the fragrance is more likely to occur in the wrapper due to the increased amount of fragrance.

[0005] An object of the present invention is to provide a non-combustion heating type flavor inhalation article with reduced wetting occurring in a wrapper surrounding a tobacco filler.

[0006] A non-combustion heating type flavor inhalation article according to one aspect of the present invention includes a tobacco part having a tobacco filler containing a tobacco filling and a volatile fragrance, and a wrapper surrounding the tobacco filler. The diffusion coefficient of the wrapper is 0 cm / s or more, and the upper limit value of the diffusion coefficient is between 0.022 cm / s and 0.10 cm / s.

Modes for Carrying Out the Invention

[0008] Hereinafter, with reference to FIGS. 1 to 5, embodiments of an electric heating type flavor suction system will be described. The drawings schematically show each component of the invention. For this reason, the dimensions on the drawings do not necessarily match the dimensions of the actual product.

[0009] [First Embodiment] As shown in FIG. 1, different from a traditional cigarette, the electric heating type flavor suction system 11 is a heating type that can warm a tobacco filler 23 without combustion by electric heating or the like and taste the flavor of tobacco.

[0010] The electric heating type flavor suction system 11 includes a main body 12 and a rod 14 (non-combustion heating type flavor suction article) that is detachably attached to the insertion portion 13 of the main body 12.

[0011] The main body 12 includes a box-shaped housing 15 and an insertion portion 13 that is recessed in a cylindrical shape along the shape of the rod 14. The main body 12 has a battery 16, a control circuit 17, a pressure sensing portion 20, a heat transfer portion 18 (heat transfer tube), and a heater 21 provided around the heat transfer portion 18 inside the housing 15. The housing 15 has a ventilation hole 22 and a switch 29 for starting the main body 12. The ventilation hole 22 communicates the outside of the housing 15 with the insertion portion 13 and can supply air to the rod 14 inserted into the insertion portion 13.

[0012] The control circuit 17 can receive power supply from the battery 16. The control circuit 17 can energize the heater 21 and adjust the temperature of the heater 21 within an appropriate range. The control circuit 17 controls the heater 21 to heat the inside of the rod 14 at, for example, 30°C to 400°C, preferably 100°C to 400°C, more preferably 150°C to 250°C. The pressure sensing portion 20 is composed of a pressure sensor (pressure sensing sensor). The pressure sensing portion 20 receives power supply from the control circuit 17. The pressure sensing portion 20 can detect that the user has sucked by sensing the negative pressure in the insertion portion 13 (inside the ventilation hole 22).

[0013] The insertion part 13 is formed by being recessed in a cylindrical shape from other parts of the housing 15.

[0014] The heat transfer part 18 has a hollow cylindrical shape. The heat transfer part 18 is formed of a metal material. The metal material constituting the heat transfer part 18 is preferably a metal with high thermal conductivity, such as gold, silver, copper, aluminum, or an alloy using them.

[0015] The heater 21 is composed of a general heating wire such as a nichrome wire, for example. The heater 21 is wound around the periphery of the heat transfer part 18 and arranged in a cylindrical shape. Note that the heating method of the heater 21 is not limited to using Joule heat due to electrical resistance. For example, an IH (Induction Heating) method may be used, or a method using a chemical reaction such as oxidation heat may be used. In that case, the material and shape of the heat transfer part suitable for the heating method may be selected. Note that the heater 21 heats the rod 14 (non-combustion heating flavor attracting article) from the outside, but it may be formed in a blade shape that can be inserted into the inside of the rod 14 (tobacco part 24) and heat the rod 14 from the inside.

[0016] (Rod) The rod 14 (non-combustion heating type flavor attracting article) shown in FIG. 2 is formed in a cylindrical shape. The circumferential length of the cylindrical rod 14 is preferably, for example, 16 mm to 27 mm, more preferably 20 mm to 26 mm, and even more preferably 21 mm to 25 mm. The total length (horizontal length) of the rod 14 is not particularly limited, but is preferably, for example, 40 mm to 90 mm, more preferably 50 mm to 75 mm, and even more preferably 50 mm to 60 mm.

[0017] Rod 14 has a tobacco part 24 filled with tobacco filler 23, a filter part 26 that constitutes a suction port 25, a connecting part 27 that connects the tobacco part 24 and the filter part 26, and a ventilation hole part 28. The ventilation hole part 28 has a plurality of through holes so as to penetrate the connecting part 27 in the thickness direction. The plurality of through holes are formed to be arranged radially when viewed from the extension line of the central axis of the rod 14. In the present embodiment, the ventilation hole part 28 is provided in the connecting part 27. The ventilation hole part 28 may be provided in the filter part 26. Also, in the present embodiment, the plurality of through holes of the ventilation hole part 28 are arranged in a row at regular intervals on an annular ring. The plurality of through holes of the ventilation hole part 28 are, for example, 124. The plurality of through holes of the ventilation hole part 28 may be arranged in two rows at regular intervals on two annular rings. The plurality of through holes of the ventilation hole part 28 may be arranged in a discontinuous or irregular manner in one row or two rows of the ventilation hole part 28. When the user holds the suction port 25 and sucks, outside air is taken into the mainstream smoke through the ventilation hole part 28.

[0018] The filter part 26 has a cylindrical shape. The filter part 26 has, for example, a rod-shaped first segment 31 filled with cellulose acetate fibers and a rod-shaped second segment 32 filled with cellulose acetate fibers. The first segment 31 is located on the tobacco part 24 side. The first segment 31 may have a hollow part. The second segment 32 is located on the suction port 25 side. The second segment 32 is solid. Each of the first segment 31 and the second segment 32 is wound around the periphery by an inner plug wrapper 33. The first segment 31 and the second segment 32 are connected by an outer plug wrapper 34. The outer plug wrapper 34 is adhered to the first segment 31 and the second segment 32 by an adhesive composed of a vinyl acetate resin-based emulsion or the like.

[0019] The length of the filter part 26 can be, for example, 10 mm to 30 mm, the length of the paper tube 35 of the connecting part 27 can be, for example, 10 mm to 30 mm, the length of the first segment 31 can be, for example, 5 mm to 15 mm, and the length of the second segment 32 can be, for example, 5 mm to 15 mm. The lengths of these individual segments are just an example and can be appropriately changed according to manufacturing suitability, required quality, the length of the tobacco part 24, etc.

[0020] For example, the first segment 31 (center hole segment) is composed of a first filling layer having one or more hollow parts and an inner plug wrapper 33 covering the first filling layer. The first segment 31 has a function of enhancing the strength of the second segment 32. The first filling layer of the first segment 31 is filled with, for example, cellulose acetate fibers at a high density. A plasticizer containing triacetin is added to this cellulose acetate fiber in an amount of, for example, 6% by mass to 20% by mass based on the mass of cellulose acetate and is cured. The hollow part of the first segment 31 has, for example, an inner diameter of φ1.0 mm to φ5.0 mm.

[0021] The first filling layer of the first segment 31 may be composed of, for example, a relatively high fiber filling density, or may be equivalent to the fiber filling density of the second filling layer of the second segment 32 described later. For this reason, during suction, air and aerosol will flow only through the hollow part, and almost no air or aerosol will flow through the first filling layer. For example, in the second segment 32, when it is desired to reduce the decrease in the aerosol component due to filtration, for example, the length of the second segment 32 can be shortened and the first segment 31 can be lengthened accordingly.

[0022] Shortening the length of the second segment 32 and lengthening the first segment 31 accordingly is effective for increasing the delivery amount of the aerosol component. Since the first filling layer of the first segment 31 is a fiber filling layer, the feel from the outside during use will not cause discomfort to the user.

[0023] The second segment 32 is composed of a second filling layer and an inner plug wrapper 33 that covers the second filling layer. The second segment 32 (filter segment) is filled with cellulose acetate fibers at a general density and has the filtering performance for general aerosol components.

[0024] The filtering performance for filtering the aerosol (mainstream smoke) emitted from the tobacco part 24 may be made different between the first segment 31 and the second segment 32. At least one of the first segment 31 and the second segment 32 may contain a flavor. The structure of the filter part 26 is arbitrary and may be a structure having a plurality of segments as described above, or may be composed of a single segment.

[0025] The connecting part 27 is cylindrical. The connecting part 27 has, for example, a paper tube 35 formed in a cylindrical shape by cardboard or the like, and a lining paper 36 (paper) surrounding the periphery of the paper tube 35. The lining paper 36 has an adhesive layer 37 formed on one surface (inner surface) thereof over the entire surface or substantially the entire surface except in the vicinity of the ventilation hole part 28. The adhesive layer 37 is composed of a vinyl acetate resin-based emulsion or the like. The lining paper 36 is wound cylindrically outside the tobacco part 24, the paper tube 35, and the filter part 26 and adhered to these through the adhesive layer 37, integrally connecting and fixing them. After the tobacco part 24, the paper tube 35, and the filter part 26 are integrated by the lining paper 36, a plurality of ventilation hole parts 28 are formed by laser processing from the outside.

[0026] The tobacco part 24 is cylindrical. The total length (axial length) of the tobacco part 24 is preferably, for example, 12 mm to 70 mm, more preferably 12 mm to 50 mm, and even more preferably 15 mm to 30 mm. The shape of the cross section of the tobacco part 24 is not particularly limited, and can be, for example, circular, elliptical, polygonal, or the like.

[0027] The tobacco portion 24 has a tobacco filler 23 and a cylindrical wrapper 41 surrounding the tobacco filler 23. The wrapper 41 is wound cylindrically around the tobacco filler 23.

[0028] (Wrapper) As shown in FIG. 3, the wrapper 41 has a paper base sheet 42 (the base sheet 1 (first sheet) in FIG. 7) and a non-metallic coating layer 43 provided on one surface of the base sheet 42. The coating layer 43 is formed by applying a resin or a thickening agent, which is a coating agent, to the base sheet 42. The coating layer 43 is provided on the surface of the base sheet 42 that contacts the tobacco filler 23. Therefore, when the wrapper 41 is wound up as the rod 14 (non-combustion heating type flavor attracting article), the coating layer 43 is disposed on the inner surface side of the wrapper 41. The arrangement of the coating layer 43 is not limited to being disposed on the inner surface side of the wrapper 41. The coating layer 43 may be provided, for example, on the surface (outer surface side) of the base sheet 42 that does not contact the tobacco filler 23, or may be provided in a pair on both surfaces of the base sheet 42. The air permeability of the wrapper 41 is, for example, less than 5 Coresta units (C.U.), preferably less than 3 Coresta units, and more preferably less than 1 Coresta unit. The diffusion coefficient of the wrapper 41 is, for example, 0 cm / s to 0.1 cm / s when measured using CO2 or N2 as a gas and under the measurement conditions of an environmental temperature of 22° C. and an environmental relative humidity of 60%, preferably 0 cm / s to 0.05 cm / s, and more preferably 0 cm / s to 0.022 cm / s. As a measuring instrument for the diffusion coefficient, a Diffusivity Tester was used. The Diffusivity Tester used was, for example, one manufactured by borgwaldt, and the measurement was performed according to the instructions issued by the company.

[0029] The base sheet 42 is composed of commercially available paper. The basis weight of the base sheet 42 is, for example, 20 g / m 2 ~50 g / m 2 and is 25 g / m 2 ~45 g / m 2It is preferably 33 g / m 2 ~39 g / m 2 More preferably, the opacity of the wrapper 41 is preferably, for example, 72% to 100%. The whiteness of the wrapper 41 is preferably, for example, 70% to 100%.

[0030] The base sheet 42 may be composed of a commercially available non-woven fabric.

[0031] The coating layer 43 contains a resin, a thickener, or a mixture thereof. A part of the resin, thickener, or mixture thereof contained in the coating layer 43 can penetrate into the micropores of the base sheet 42 to block the micropores, thereby making the diffusion coefficient of the wrapper 41 within the range of 0 cm / s to 0.022 cm / s.

[0032] When the coating layer 43 is composed mainly of a resin, the resin may be polyvinyl alcohol (PVA) or polyvinyl acetate (PVAc), or a composition (mixture) in which these are mixed may be used. When the coating layer 43 is composed mainly of a resin, the resin may be configured as a composition further containing a filler. The filler may be any one of calcium carbonate, aluminum hydroxide, aluminum oxide, titanium dioxide, kaolin, talc, or silica, or a mixture of some of these. By including a filler in the coating layer 43 in this way, there are advantages such as preventing blocking between the wrappers 41, preventing curling of the wrapper 41, and further improving the whiteness / opacity of the wrapper 41.

[0033] When the coating layer 43 is composed mainly of a thickener, the thickener may be any one of gum arabic, starch, sodium alginate, pectin, carboxymethyl cellulose, methyl cellulose, ethyl cellulose, microcrystalline cellulose, or hydroxypropyl methyl cellulose (HPMC), or it may be a composition in which several of these are mixed. When the coating layer 43 is mainly composed of a thickener, the thickener may be configured as a composition further containing a filler. The filler may be any one of calcium carbonate, aluminum hydroxide, aluminum oxide, titanium dioxide, kaolin, talc, or silica, or it may be a mixture of several of these. By including a filler in the coating layer 43 in this way, there are advantages such as preventing blocking (adhesion) between the wrappers 41, preventing curling of the wrapper 41, and further improving the whiteness / opacity of the wrapper 41.

[0034] The coating layer 43 may be configured as a composition (mixture) containing both the resin as described above and the thickener as described above as main components. In that case, the coating layer 43 may be configured as a composition further containing a mixture of any one or two or more of the fillers described above.

[0035] The amount of the coating agent for forming the coating layer 43 applied to the base sheet 42 varies depending on the type of the coating agent. For example, when using gum arabic as the coating agent, the coating amount per 1 m 2 is preferably larger than a very small amount, for example, 0 g / m 2 and less than 10 g / m 2 When using polyvinyl alcohol as the coating agent, the coating amount per 1 m 2 is preferably larger than a very small amount, for example, 0 g / m 2 and less than 10.0 g / m 2 When using polyvinyl acetate as the coating agent, the coating amount per 1 m 2 is preferably larger than a very small amount, for example, 0 g / m2 greater than and preferably less than 10.0 g / m 2 The lower limit of the coating amount of each substance is preferably set to the required amount while measuring the diffusion coefficient.

[0036] As shown in FIG. 4, the wrapper 41 has one end 41A and the other end 41B provided on the side opposite to the one end 41A. In a state of being wound around the tobacco filler 23, the other end 41B is adhesively bonded to the upper side of the one end 41A via an adhesive 45. For this reason, the one end 41A and the other end 41B constitute an overlapping portion 44 that is overlapped and adhered to each other. A surface treatment for improving wettability is applied to the coating layer 43 in the portion corresponding to the other end 41B. This surface treatment may be, for example, a corona treatment, a plasma treatment, or other surface modification treatments. By performing the surface treatment in this way, the surface to which the surface treatment is applied becomes the adhesive surface 47 between the one end 41A and the other end 41B, and the adhesion via the adhesive 45 between them becomes strong.

[0037] In the present embodiment, a surface treatment for improving wettability is performed on the coating layer 43 in the portion corresponding to the other end 41B. A surface treatment for improving wettability may be performed on the coating layers 43 of both the one end 41A and the other end 41B. Alternatively, the following structure may be adopted as an alternative to this surface treatment. That is, a non-forming region 46 where the coating layer 43 is not formed may be provided at a position corresponding to either the one end 41A or the other end 41B. In the example of FIG. 4, the non-forming region 46 is provided at a position corresponding to the other end 41B.

[0038] An adhesive 45 for adhering the one end 41A and the other end 41B is applied to the surface to which the surface treatment is applied or the non-forming region 46. The adhesive 45 is composed of, for example, a vinyl acetate resin-based emulsion. The surface to which the surface treatment is applied or the non-forming region 46 forms the adhesive surface 47 between the one end 41A and the other end 41B together with the adhesive 45.

[0039] The wrapper 41 may contain a flavor component. Specifically, the base sheet 42 of the wrapper 41 may contain a flavor component, or the coating layer 43 of the wrapper 41 may contain a flavor component.

[0040] The tobacco filler 23 is composed of cut leaf tobacco (dried leaves) and / or a sheet-shaped formed product obtained by cutting a sheet-shaped product formed by shaping ground leaf tobacco into a predetermined width (sheet-shaped formed product). The tobacco filler 23 is formed by randomly filling a sheet-shaped formed product obtained by cutting a sheet-shaped product formed by shaping ground leaf tobacco into a predetermined width (sheet-shaped formed product) and / or cut leaf tobacco (dried leaves). The aerosol-generating substrate and flavor component may be contained in this sheet-shaped formed product. The aerosol-generating substrate and flavor component may be added to and contained in the cut leaf tobacco.

[0041] (Tobacco filler) The tobacco filler 23 according to the present invention contains a tobacco filler (tobacco) and an aerosol-generating substrate. The tobacco filler 23 may further contain a volatile flavor, water, etc., which will be described later. There are no particular restrictions on the size of the tobacco used as the tobacco filler and its preparation method. For the tobacco filler, for example, dried tobacco leaves cut into slender strips with a width of 0.8 mm to 1.2 mm can be used. When cut to the above width, the length of the cut tobacco leaves is approximately 1 mm to 40 mm. Also, dried tobacco leaves are pulverized and homogenized so that the average particle size is, for example, about 20 μm to 200 μm, then sheet processed, and the resulting sheet is cut into slender strips with a width of 0.8 mm to 1.2 mm (tobacco regenerated sheet, sheet-shaped formed product) may be included as the tobacco filler. When cut to the above width, the length of the cut is approximately, for example, 1 mm to 40 mm. Further, a gathered and folded product without cutting the above sheet-processed product may be used as the tobacco filler. Whether using cut dried tobacco leaves or using a pulverized and homogenized sheet, various types of tobacco can be used as the tobacco filler.

[0042] For tobacco fillers, yellow varieties, Burley varieties, Oriental varieties, native varieties, and other Nicotiana tabacum varieties, Nicotiana rustica varieties, and Nicotiana tomentosa varieties can be appropriately blended and used according to the desired taste. The details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Comprehensive Research Center, March 31, 2009".

[0043] There are multiple conventional methods for processing tobacco into a homogenized sheet (tobacco recycled sheet). One is a paper-making sheet made using a papermaking process. The second is a cast sheet made by mixing an appropriate solvent such as water and the necessary types / amounts of binders with the tobacco ground material, homogenizing them, and then thinly casting the homogenized material onto a metal plate or a metal plate belt and drying it. The third is a rolled sheet obtained by extruding and molding into a sheet shape the material obtained by mixing an appropriate solvent such as water and the necessary types / amounts of binders with the tobacco ground material and homogenizing it. The details of the types of the homogenized sheet (tobacco recycled sheet) are disclosed in "Tobacco Encyclopedia, Tobacco Comprehensive Research Center, March 31, 2009".

[0044] For the tobacco filler 23, it is preferable that an aerosol-forming substrate and a volatile fragrance are applied or contained to the tobacco leaves (dried leaves) and the material obtained by forming the ground tobacco leaves into a sheet shape. The aerosol-forming substrate is preferably contained at, for example, 5% by weight to 30% by weight with respect to the material obtained by forming the tobacco leaves (dried leaves) and the material obtained by forming the ground tobacco leaves into a sheet shape. The aerosol-forming substrate is a material capable of generating an aerosol by heating, and examples thereof include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1,3-butanediol, and the like. These may be used alone or in combination of two or more. The aerosol-forming substrate preferably contains glycerin.

[0045] The filling density of the tobacco filler 23 is not particularly limited, but from the viewpoint of ensuring the performance of the rod 14 (non-combustion heating type flavor inhalation article) and imparting good taste, it is usually 250 mg / cm 3 ~700 mg / cm3 and preferably 320 mg / cm 3 ~420 mg / cm 3 Specifically, in the case of the tobacco part 24 with a circumference of 22 mm and a length of 20 mm, the content range of the tobacco filler 23 in the tobacco part 24 can be 200 mg to 400 mg per tobacco part 24, and more preferably 250 mg to 320 mg.

[0046] The volatile fragrance (fragrance component) contained in the tobacco filler 23 can be any fragrance without limitation as long as it is a fragrance used in the electric heating type fragrance inhalation system 11. The fragrance components include l-menthol, natural plant fragrances (e.g., cinnamon, sage, herb, chamomile, kudzu, amacha, clove, lavender, cardamom, star anise, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon bark, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang-ylang, fennel, anise, licorice, centaury, plum extract, peach extract, etc.), saccharides (e.g., glucose, fructose, isomerized sugar, caramel, etc.), cocoas (powder, extract, etc.), esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (e.g., menthone, ionone, damasconone, ethyl maltol, etc.), alcohols (e.g., geraniol, linalool, anethole, eugenol, etc.), aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g., γ-undecalactone, γ-nonalactone, etc.), animal fragrances (e.g., musk, ambergris, civet, castoreum, etc.), hydrocarbons (e.g., limonene, pinene, etc.), and extracts of tobacco plants (tobacco leaves, tobacco stems, tobacco flowers, tobacco roots, and tobacco seeds). One kind selected from the group consisting of these can be used. Particularly preferred as the volatile fragrance contained in the tobacco filler 23 is l-menthol. Alternatively, the volatile fragrance contained in the tobacco filler 23 may be used by mixing two or more kinds selected from the above group.

[0047] The flavor components contained in the tobacco filler 23 may be used in solid form, or may be dissolved or dispersed in a suitable solvent such as propylene glycol, ethyl alcohol, benzyl alcohol, or triethyl citrate and used. Preferably, flavors that are easily dispersed in the solvent by the addition of an emulsifier, such as hydrophobic flavors or oil-soluble flavors, can be used. These flavor components may be used alone or in combination.

[0048] The content of the volatile flavor in the tobacco filler 23 is not particularly limited. From the viewpoint of imparting good taste, the tobacco filler preferably contains 0.5% to 10% by weight of the volatile flavor based on the weight of the tobacco filler, more preferably contains 1% to 9% by weight of the volatile flavor based on the weight of the tobacco filler, and even more preferably contains 1.2% to 8% by weight of the volatile flavor based on the weight of the tobacco filler.

[0049] (Method for manufacturing the tobacco part) Prior to the manufacture of the tobacco part 24, a coating agent is applied to the base sheet 42 to form the wrapper 41. The wrapper 41 is formed by applying a coating agent that becomes the coating layer 43 to one surface of the base sheet 42 wound in a roll shape. As a method for applying the coating agent, various coating methods can be adopted. For example, flexo, gravure, die coat, gate roll coat, or other coating methods can be used.

[0050] In the wrapper 41 in which the coating layer 43 is formed on the surface of the base sheet 42, the coating layer 43 corresponding to at least one of one end 41A and the other end 41B is preferably subjected to, for example, corona treatment, plasma treatment, or other surface treatment. In particular, in the example of FIG. 4 of the present embodiment, the coating layer 43 corresponding to the other end 41B is preferably subjected to, for example, corona treatment, plasma treatment, or other surface treatment.

[0051] As a result, the wettability (affinity) for the adhesive 45 is improved at at least one of one end 41A and the other end 41B. The adhesive 45 is applied to the surface thus surface-treated. Then, one end 41A and the other end 41B are adhered to form a cylindrical tobacco part 24 by winding the wrapper 41 around the tobacco filler 23. At this time, the surface thus surface-treated becomes the adhesive surface 47 between one end 41A and the other end 41B, and the affinity of the adhesive 45 for the coating layer 43 is improved, forming a strong adhesive part.

[0052] Alternatively, instead of such a surface treatment step, a non-formation region 46 where the coating layer 43 is not formed may be provided on either one of one end 41A and the other end 41B of the wrapper 41. The adhesive 45 is applied to the non-formation region 46, and one end 41A and the other end 41B are adhered to form a cylindrical tobacco part 24 by winding the wrapper 41 around the tobacco filler 23. At this time, the non-formation region 46 is used as the adhesive surface 47 between one end 41A and the other end 41B. In this way, the non-formation region 46 on the base sheet 42 becomes the adhesive surface 47, and since the coating layer 43 does not intervene in the adhesive surface 47, a strong adhesive part is formed.

[0053] The wrapper 41 that has been surface-treated or in which the non-formation region 46 is formed is introduced into a general tobacco rolling machine and wound around the tobacco filler 23 to form an elongated cylindrical shape. At this time, the wrapper 41 is set in the tobacco rolling machine so that the coating layer 43 is on the inner side (the tobacco filler 23 side). Then, the tobacco filler 23 and the wrapper 41 formed in an elongated cylindrical shape are cut to a predetermined length by a cutter or the like. Thereby, the tobacco part 24 is formed. The tobacco part 24 is arranged in series with a separately prepared paper tube 35 and the filter part 26. These tobacco parts 24, paper tubes 35, and filter parts 26 are wound up in series and integrally by a lining paper 36. Through the above steps, the rod 14 of the electrically heated flavor suction system 11 is manufactured.

[0054] The main body 12 of the electric heating type fragrance attracting system 11 can also be manufactured by a known method for manufacturing electronic devices. By combining the rod 14 and the main body 12 manufactured in this way, the electric heating type fragrance attracting system 11 is realized.

[0055] (Operation of the electric heating type fragrance attracting system) As shown in FIG. 5, by inserting the rod 14 into the insertion portion 13 of the main body 12, the rod 14 is attached to the main body 12. In this state, when the user presses the switch 29 to activate the main body 12, the control circuit 17 drives the heater 21 to raise the temperature of the heater 21 and the heat transfer portion 18 to a predetermined temperature (for example, 30°C to 400°C). As a result, the tobacco portion 24 is heated. In this state, when the user holds the suction port 25 and starts suction, vapor (aerosol) containing the fragrance of tobacco is released from the tobacco portion 24. The vapor is cooled by the air that has flowed into the inside of the connecting portion 27 from the vent hole portion 28, and more reliable aerosolization (atomization into minute droplets) is performed.

[0056] The aerosol is appropriately filtered by the filter portion 26 and delivered into the user's oral cavity. As a result, the user can taste the fragrance of tobacco. At this time, the control circuit 17 senses the negative pressure inside the housing 15 via the pressure sensing portion 20. As a result, the control circuit 17 can count the number of times the user has performed suction, calculate the total suction time, etc. The control circuit 17 stops heating the heater 21 and the heat transfer portion 18 when a predetermined time has elapsed after the switch 29 is pressed, when the user has performed suction a predetermined number of times, when the user's total suction time exceeds a predetermined time, or when the user presses the switch 29 again to cancel the activated state. As a result, one fragrance attracting operation is completed. Then, when the user removes the used rod 14 from the insertion portion 13 and inserts a new rod 14 into the insertion portion 13, the user can taste the fragrance of tobacco from the new rod 14 again.

[0057] In the rod 14 (non-combustion heating type fragrance attracting article) of the present embodiment, due to the coating layer 43, the diffusion coefficient of the wrapper 41 is suppressed to 0 cm / s to 0.022 cm / s. Therefore, the volatile fragrance volatilized in the rod 14 during storage does not permeate through the wrapper 41, and the volatile fragrance does not form a stain on the surface of the wrapper 41. Also, even during storage at a low temperature, the volatilized volatile fragrance does not permeate through the wrapper 41. Although the details of the mechanism of crystal formation by the volatile fragrance (especially l-menthol) during low-temperature storage are unknown, it is considered that the volatile fragrance that permeates through the micropores of the wrapper 41 and adheres to the outer surface of the wrapper 41 becomes the nucleus of the crystal, and then the crystal grows to form a hairy (fibrous) crystal by the volatile fragrance. In the present embodiment, permeation of the volatile fragrance through the wrapper 41 is suppressed. Therefore, it is considered that the first volatile fragrance that becomes the nucleus of the crystal is prevented from adhering to the outer surface of the wrapper 41. Therefore, in the rod 14 of the present embodiment, not only the generation of stains on the surface of the wrapper 41 but also the generation of fibrous crystals by the volatile fragrance on the surface of the wrapper 41 during low-temperature storage are prevented.

[0058] According to the first embodiment, the following can be said.

[0059] The non-combustion heating type fragrance attracting article includes a tobacco part 24 having a tobacco filler 23 containing a tobacco filling and a volatile fragrance, and a wrapper 41 surrounding the tobacco filler 23. The wrapper 41 has a base material sheet 42 and a non-metallic coating layer 43 provided on the surface of the base material sheet 42 that contacts the tobacco filler 23, and the diffusion coefficient of the wrapper 41 is 0 cm / s to 0.022 cm / s.

[0060] According to this configuration, by providing the coating layer 43, it is possible to block the micropores in the base sheet 42 until the diffusion coefficient reaches a level of 0 cm / s to 0.022 cm / s. Therefore, it is possible to prevent the volatile fragrance from permeating through the wrapper 41. As a result, it is possible to prevent the volatile fragrance in the tobacco filler 23 from forming a stain on the wrapper 41. Further, when the non-combustion heating type fragrance attracting article is stored at a low temperature, fibrous crystals may be generated from the surface of the wrapper 41 due to the volatilized volatile fragrance. According to the non-combustion heating type fragrance attracting article of the present embodiment, the generation of such fibrous crystals due to the volatile fragrance is prevented. As a result, the user does not feel uncomfortable with the appearance of the non-combustion heating type fragrance attracting article, and a high-quality non-combustion heating type fragrance attracting article can be provided.

[0061] The coating layer 43 contains a resin, a thickener, or a mixture thereof. According to this configuration, the coating layer 43 can block the micropores in the base sheet 42.

[0062] The resin is polyvinyl alcohol or polyvinyl acetate. According to this configuration, it is possible to obtain a wrapper 41 with a sufficiently reduced diffusion coefficient with a small coating amount on the base sheet 42.

[0063] The thickener is gum arabic, starch, sodium alginate, pectin, carboxymethyl cellulose, or methyl cellulose. According to this configuration, it is also possible to obtain a wrapper 41 with a sufficiently reduced diffusion coefficient by using various thickeners.

[0064] The coating layer 43 further contains a filler. According to this configuration, since the coating layer 43 contains fine particulate fillers, it is possible to more efficiently block the micropores in the base sheet 42. Further, so-called blocking in which the wrappers 41 before winding up stick to each other during storage is prevented, and curling of the wrapper 41 can be effectively prevented. Furthermore, the whiteness / opacity of the wrapper 41 can be improved.

[0065] The filler is calcium carbonate, aluminum hydroxide, aluminum oxide, titanium dioxide, microcrystalline cellulose, kaolin, talc, or silica. According to this configuration, blocking between the wrappers 41 can be prevented, and curling of the wrapper 41 can be effectively prevented. Furthermore, the whiteness / opacity of the wrapper 41 can be improved.

[0066] The volatile fragrance is l-menthol. L-menthol is likely to volatilize in the package during storage, and is likely to cause problems such as soaking into the wrapper 41 during storage or forming fibrous (needle-like) crystals on the wrapper 41 during storage at low temperatures. According to the above configuration, even when the volatile fragrance is l-menthol, it is possible to prevent problems such as soaking into the wrapper 41 during storage or forming fibrous crystals from the wrapper 41 during storage at low temperatures.

[0067] The tobacco filler 23 contains 1.2% by weight or more of the volatile fragrance with respect to the weight of the tobacco filling. Usually, in the tobacco filler 23 with a large content of the volatile fragrance in this way, the volatile fragrance may soak into the wrapper 41 to form a stain or form crystals on the surface of the wrapper 41. According to this configuration, even when using the tobacco filler 23 with a large content of the volatile fragrance that is likely to cause stains and crystals in this way, it is possible to effectively prevent the wrapper 41 from getting stained or forming crystals.

[0068] The air permeability of the wrapper 41 is less than 1 Coresta unit. According to this configuration, the air permeability of the wrapper 41 can be made low, thereby further reducing the possibility of the volatile fragrance permeating through the wrapper 41. This can prevent problems such as the wrapper 41 getting stained during storage or forming fibrous crystals on the wrapper 41 during storage at low temperatures.

[0069] The base sheet 42 is paper and / or non-woven fabric. According to this configuration, the appearance of the wrapper 41 of the non-combustion heating type fragrance attracting article can be made similar to that of a traditional paper cigarette, and it is possible to prevent the user from feeling uncomfortable.

[0070] In this case, the wrapper 41 has one end portion 41A and the other end portion 41B provided on the side opposite to the one end portion 41A and bonded to the one end portion 41A. The coating layer 43 of the portion corresponding to at least one of the one end portion 41A and the other end portion 41B is subjected to a surface treatment for improving wettability, and the surface on which the surface treatment is performed forms the adhesive surface 47 between the one end portion 41A and the other end portion 41B.

[0071] Further, the method for manufacturing a non-combustion heating type fragrance attracting article includes applying a coating agent containing a resin or a thickening agent to the base sheet 42 to form a wrapper 41 having a coating layer 43, and applying a surface treatment for improving wettability to the coating layer 43 of the portion corresponding to at least one of the one end portion 41A of the wrapper 41 and the other end portion 41B provided on the side opposite to the one end portion 41A and bonded to the one end portion 41A, and using the surface-treated surface as the adhesive surface 47, bonding the one end portion 41A and the other end portion 41B with the adhesive surface 47 to surround the tobacco filler 23 containing the volatile fragrance with the wrapper 41.

[0072] According to these configurations, it is possible to prevent the adhesive strength of the adhesive portion of the wrapper 41 from decreasing due to the provision of the coating layer 43. Thereby, it is possible to prevent problems such as poor adhesion in the overlapping portion of the wrapper 41.

[0073] In this case, the wrapper 41 has one end portion 41A and the other end portion 41B provided on the side opposite to the one end portion 41A and bonded to the one end portion 41A. The portion corresponding to either one of the one end portion 41A and the other end portion 41B has a non-formation region 46 where the coating layer 43 is not formed. The non-formation region 46 forms the adhesive surface 47 between the one end portion 41A and the other end portion 41B.

[0074] According to this configuration, it is possible not to provide the coating layer 43 on the portion that becomes the adhesion surface 47. As a result, it is possible to prevent a decrease in the adhesion strength at the overlapping portion of the wrapper 41 due to the provision of the coating layer 43. Further, by leaving the coating layer 43 on either one of the one end portion 41A and the other end portion 41B, the diffusion coefficient of the wrapper can be maintained within the range of 0 cm / s to 0.022 cm / s.

[0075] The electric heating type fragrance attracting system 11 includes a non-combustion heating type fragrance attracting article and a heater 21 that heats the non-combustion heating type fragrance attracting article. According to this configuration, it is possible to realize an electric heating type fragrance attracting system 11 that prevents the wrapper 41 from being stained by the volatile fragrance and prevents fibrous (acicular) crystals from being generated during low-temperature storage.

[0076] The heater 21 heats the non-combustion heating type fragrance attracting article at 30°C to 400°C. In a conventional traditional cigarette, since combustion is involved, the heating temperature of the tobacco filler 23 is as high as 700°C to 900°C. According to the above configuration, since the heating temperature of the tobacco portion 24 is significantly lower than that of a traditional cigarette, it is necessary to increase the amount of the volatile fragrance contained in the tobacco filler 23 so that the user can feel the same strength of the volatile fragrance in the aerosol. Then, when the amount of the volatile fragrance is increased in this way, there are problems that the wrapper 41 is likely to be stained by the volatile fragrance and fibrous crystals are likely to be generated from the wrapper 41 during low-temperature storage. According to the present embodiment, even when the amount of the volatile fragrance is increased in this way, it is possible to effectively prevent the wrapper 41 from being stained and fibrous crystals from being generated from the wrapper 41. As a result, it is possible to realize a high-quality non-combustion heating type fragrance attracting article and an electric heating type fragrance attracting system 11 including the same.

[0077] [First Modified Example] As shown in FIG. 6, the wrapper 41 may be formed only of a paper-based base sheet 42 (the base sheet 1 in FIG. 9). As the paper-based base sheet 42, for example, glassine paper is used. Glassine paper can suppress micropores in the base sheet 42 and reduce the diffusion coefficient. For this reason, the coating layer 43 is not necessarily required.

[0078] Note that if it is possible to suppress micropores in the base sheet 42 and reduce the diffusion coefficient, a nonwoven base sheet 42 may be used instead of the paper-based base sheet 42 such as glassine paper.

[0079] According to the first modification of the first embodiment, the following can be said.

[0080] The non-combustion heating type flavor attracting article includes a tobacco part 24 having a tobacco filler 23 containing a tobacco filling and a volatile fragrance, and a wrapper 41 surrounding the tobacco filler 23. The wrapper 41 has a paper-based or nonwoven base sheet 42, and the diffusion coefficient of the wrapper 41 is 0 cm / s to 0.006 cm / s.

[0081] According to this configuration, by appropriately selecting the base sheet 42, that is, the wrapper 41, it is possible to prevent the volatile fragrance from permeating through the wrapper 41. As a result, it is possible to prevent the volatile fragrance in the tobacco filler 23 from forming a stain on the wrapper 41. Further, when the non-combustion heating type flavor attracting article is stored at a low temperature, fibrous crystals may be generated from the surface of the wrapper 41 due to the volatilized volatile fragrance. According to the non-combustion heating type flavor attracting article of the present embodiment, the generation of such fibrous crystals due to the volatile fragrance is prevented. As a result, the user does not feel uncomfortable with the appearance of the non-combustion heating type flavor attracting article, and a high-quality non-combustion heating type flavor attracting article can be provided.

[0082] [Second Modification Example] As shown in FIG. 7, the wrapper 41 preferably has, in addition to the paper base sheet 42 (the base sheet 1 (the first sheet) in FIG. 9), a second base sheet 42A (the base sheet 2 (the second sheet) in FIG. 9) made of the same or a different material from the base sheet 42 inside the coating layer 43. That is, the coating layer 43 is sandwiched between the base sheet 42 and the base sheet 42A. By making the wrapper 41 have a three-layer structure and suppressing the micropores in the base sheet 42, the diffusion coefficient can be reduced.

[0083] In addition, as long as the micropores in the base sheet 42 can be suppressed and the diffusion coefficient can be reduced, a non-woven fabric base sheet 42 may be used instead of the paper base sheet 42. Similarly, as long as the micropores in the base sheet 42A can be suppressed and the diffusion coefficient can be reduced, a non-woven fabric base sheet 42A may be used instead of the paper base sheet 42A.

[0084] According to the second modification of the first embodiment, the following can be said.

[0085] The non-combustion heating type fragrance attracting article includes a tobacco part 24 having a tobacco filler 23 containing a tobacco filling and a volatile fragrance, and a wrapper 41 surrounding the tobacco filler 23. The wrapper 41 has a plurality of base sheets 42, 42A made of paper or non-woven fabric, and a coating layer 43 formed between the base sheets 42, 42A, and the diffusion coefficient of the wrapper 41 is 0.001 cm / s to 0.015 cm / s.

[0086] According to this configuration, by appropriately selecting the base sheets 42, 42A and the material for forming the coating layer 43, i.e., the wrapper 41, it is possible to prevent the volatile fragrance from permeating through the wrapper 41. As a result, it is possible to prevent the volatile fragrance in the tobacco filler 23 from soaking into the wrapper 41. Also, when the non-combustion heating type fragrance attracting article is stored at a low temperature, fibrous crystals may be formed on the surface of the wrapper 41 due to the volatilized volatile fragrance. According to the non-combustion heating type fragrance attracting article of the present embodiment, the formation of such fibrous crystals due to the volatile fragrance is prevented. As a result, the user does not feel uncomfortable with the appearance of the non-combustion heating type fragrance attracting article, and a high-quality non-combustion heating type fragrance attracting article can be provided.

[0087] [Second Embodiment] With reference to FIG. 8, the electric heating type fragrance attracting system 11 of the second embodiment and the non-combustion heating type fragrance attracting article (rod 14) included therein will be described. In the present embodiment, although the shape of the rod 14 is different, other parts are common to the first embodiment. Hereinafter, mainly, the rod 14, which is the part different from the first embodiment, will be described, and the illustration and description of the parts common thereto will be omitted.

[0088] The rod 14 has a tobacco part 24 filled with a tobacco filler 23, a filter part 26 constituting a suction port 25, a connecting part 27 connecting the tobacco part 24 and the filter part 26, an additional segment 51 (second filter part) provided adjacent to the tobacco part 24, and a ventilation hole part 28. The tobacco part 24, the filter part 26, and the ventilation hole part 28 have the same configuration as in the first embodiment. The wrapper 41 of the tobacco part 24 preferably has the same configuration as in the first embodiment, as well as the same configurations as in the first modification example and the second modification example.

[0089] The additional segment 51 (second filter part) is formed in a cylindrical shape and is provided so as to cover (block the view of) the second end face 24B on the side opposite to the first end face 24A facing the filter part 26 of the tobacco part 24. More specifically, the additional segment 51 is provided adjacent to the tobacco part 24 so as to cover the second end face 24B of the tobacco part 24. The additional segment 51 has air permeability, and particularly has high air permeability in the axial direction of the cylinder.

[0090] In the present embodiment, the additional segment 51 is a rod-shaped filter filled with cellulose acetate fibers. The additional segment 51 is configured as a center hole segment having a hollow part 51A at the center, similar to the first segment 31 of the filter part 26 in the first embodiment, but the embodiment of the additional segment 51 is not limited to this. The additional segment 51 may be configured as a solid filter without a center hole, similar to the second segment 32 of the filter part 26, or may be configured as an annular protruding part in which the lining paper 36 of the connecting part 27 protrudes to the tip side (the side opposite to the suction port 25) from the tobacco part 24 (tobacco filler 23) (in this case, the inside of the protruding part is formed as a cavity).

[0091] The connecting part 27 has, for example, a paper tube 35 formed in a cylindrical shape by cardboard or the like, and a lining paper 36 surrounding the periphery of the paper tube 35. An adhesive composed of a vinyl acetate resin-based emulsion or the like is applied to one surface (inner surface) of the lining paper 36 over the entire surface or substantially the entire surface except for the vicinity of the ventilation hole part 28. The lining paper 36 is wound cylindrically outside the additional segment 51, the tobacco part 24, the paper tube 35, and the filter part 26 to integrally connect them. After the tobacco part 24, the paper tube 35, and the filter part 26 are integrated by the lining paper 36, a plurality of ventilation hole parts 28 are formed by laser processing from the outside.

[0092] The means for connecting the additional segment 51 to the tobacco part 24 is not limited to the lining paper 36. It is of course possible to connect the additional segment 51 and the tobacco part 24 by a roll paper provided separately from the lining paper 36.

[0093] The operation of the rod 14 (non-combustion heating type flavor attracting article) of the present embodiment will be described. The rod 14 of the present embodiment has an additional segment 51 for covering the tip side of the tobacco part 24. For this reason, it is possible to prevent the formation of hairy (fibrous, needle-like) crystals due to the volatile fragrance (particularly, l-menthol) from the exposed part of the tobacco filler 23 of the tobacco part 24 during storage at low temperature.

[0094] When the additional segment 51 is composed of a center hole segment having a hollow part 51A at the center or an annular protrusion formed by the lining paper 36, during low-temperature storage, crystals of the volatile fragrance that have grown from the exposed part of the tobacco filler 23 will be generated inside the hollow part 51A of the additional segment 51 or inside the protrusion. However, if it is inside the hollow part 51A or the protrusion, the user cannot visually recognize it from the outside, and since the fibrous (needle-like) crystals will decompose within a short time during the process of returning the rod to room temperature, it does not substantially cause a problem. Also, by making the additional segment 51 a center hole segment or a protrusion, it is possible to prevent an increase in the ventilation resistance as much as possible, and prevent the additional segment 51 from becoming a design constraint for the rod 14.

[0095] According to the present embodiment, the following can be said.

[0096] The non-combustion heating type fragrance attracting article includes an additional segment 51 which is provided adjacent to the tobacco part 24 and has air permeability, and which is provided so as to cover the second end face 24B on the side opposite to the first end face 24A facing the filter part 26 of the tobacco part 24. According to this configuration, even when fibrous crystals are generated from the tobacco filler 23 located on the second end face 24B due to the volatile fragrance during low-temperature storage, the additional segment 51 can cover the crystals. As a result, it is possible to prevent the problem that the crystals are visually recognized by the user and the product is misinterpreted as being contaminated with fibers or the like.

[0097] The non-combustion heating type fragrance attracting article and the electric heating type fragrance attracting system 11 are not limited to those described in the above embodiments and each modification, and the components can be modified and embodied without departing from the gist thereof at the implementation stage. Also, some components may be deleted from all the components shown in the embodiments.

Example

[0098] Hereinafter, Examples 1 to 8 and Comparative Examples 1 to 6 in which the rod 14 was formed by changing the type of the wrapper 41 will be described according to the table shown in FIG. 9. Prior to the description of each example and comparative example, the method for measuring the diffusion coefficient, the method for evaluating the bleeding occurrence rate, and the method for evaluating the generation of crystals will be described.

[0099] <Method for Measuring Diffusion Coefficient> The diffusion coefficient was measured using N2 and CO2 as gases under the measurement conditions of 22°C and a relative humidity of 60% with a Diffusivity Tester manufactured by Borgwaldt. Other measurement conditions were in accordance with the instruction manual issued by the company.

[0100] <Method for Evaluating Bleeding Occurrence Rate and Bleeding Suppression Effect> For the evaluation, a tobacco rod with a circumference of 22 mm and a length of 56 mm (a long tobacco rod for cigarettes) was used. As the tobacco rod for evaluation, a tobacco filler 23 containing 6% by weight of l-menthol (volatile fragrance) with respect to the weight of the tobacco filler was used. The finished tobacco rod using this tobacco filler 23 was stored in an airtight (gas barrier) sealed container at room temperature for 14 days, and the number of stains generated was evaluated. For one tobacco rod, those with 5 or more stains having a maximum diameter of 1 mm or more, or those with 1 or more stains having a maximum diameter of 3 mm or more were defined as stained rods.

[0101] The stain occurrence rate was calculated as follows. 200 tobacco rods configured as described above were prepared, and after storing them under the above conditions for 14 days, they were observed and the number of stained rods was counted. The ratio of the number of stained rods to the total number (200) was taken as the stain occurrence rate (%).

[0102] Those with a stain occurrence rate of less than 35% were defined as having a stain suppressing effect "〇", and those with a stain occurrence rate of 35% or more were defined as having no stain suppressing effect "×".

[0103] <Evaluation method for crystal generation> As the tobacco rod for evaluation, the same tobacco rod as the tobacco rod (long tobacco rod for cigarettes) used for the evaluation of the above-described stain occurrence rate and stain suppressing effect was used. As the tobacco rod for evaluation, a tobacco filler 23 containing 6% by weight of l-menthol (volatile fragrance) with respect to the weight of the tobacco filler was used. The finished tobacco rod using this tobacco filler 23 was stored in a refrigerator at 4°C in an airtight (gas barrier) sealed container for 14 days. After storage, the presence or absence of fibrous (acicular) crystals of l-menthol was evaluated. Those without fibrous crystals on the surface of the wrapper 41 were defined as having an effect "〇", and those with fibrous crystals on the surface of the wrapper 41 were defined as having no effect "×".

[0109] As the coating substance used for the coating layer 43 of the wrapper 41, polyvinyl alcohol (PVA) which is a resin was used. This polyvinyl alcohol was applied to one surface of the base material sheet 42 using a flexo coater to form the wrapper 41. The coating amount (coating weight) of the polyvinyl alcohol on the base material sheet 42 was 3.8 g / m 2 was set.

[0110] The total basis weight of this wrapper 41 was 40 g / m2 It was. The opacity of the wrapper 41 including the base sheet 42 and the coating layer 43 was 80%. The whiteness of this wrapper 41 was 88%.

[0111] The diffusion coefficient of the wrapper 41 was 0.000 cm / s. The air permeability of the wrapper 41 was less than 1 Coresta unit.

[0113] As the coating substance used for the coating layer 43 of the wrapper 41, ethylene vinyl acetate copolymer (EVA), which is a resin, was used. This ethylene vinyl acetate copolymer was applied to one side of the base sheet using a coater to form the wrapper 41. The coating amount (coating weight) of the ethylene vinyl acetate copolymer with respect to the base sheet 42 was 4.5 g / m 2 was set.

[0114] The total basis weight of this wrapper 41 was 41 g / m 2 It was. The opacity of the wrapper 41 including the base sheet 42 and the coating layer 43 was 81%. The whiteness of this wrapper 41 was 89%.

[0149] [Discussion] Considering Examples 1-8 and Comparative Examples 1-6 described above, the following can be said.

[0150] The diffusion coefficient of the wrapper 41 in Comparative Example 1 is 1 cm / s or more, which is higher than that of Examples 1-8. The diffusion coefficient of the wrapper 41 in Comparative Example 2 is 0.101 cm / s, which is higher than that of Examples 1-8. The diffusion coefficients of the wrappers 41 in Comparative Examples 3-6 are 0.245 cm / s or more, which are higher than that of Examples 1-8. The lower limit of the diffusion coefficients of Comparative Examples 1-6 is 0.101 cm / s of Comparative Example 2. Therefore, it is recognized that in order to have a stain suppression effect and a crystal suppression effect, the diffusion coefficient of the wrapper 41 needs to be less than at least 0.101 cm / s. In particular, as in Examples 1-8, the wrapper 41 with a diffusion coefficient of 0 cm / s to 0.022 cm / s is recognized as an example having a stain suppression effect and a crystal suppression effect. It can be said that the upper limit value of the diffusion coefficient of the wrapper 41 is between 0.022 cm / s and 0.101 cm / s. From the above, it is recognized that the diffusion coefficient of the wrapper 41 contributes significantly in order to have a stain suppression effect and a crystal suppression effect. It was found that the diffusion coefficient of the wrapper 41 is 0 cm / s or more, and the upper limit value of the diffusion coefficient is between 0.022 cm / s and 0.10 cm / s.

[0151] The air permeability of Examples 1-8 was such that 6 / 8 of the examples were 1 Gurley unit or less, and the highest value was 2.3 Gurley units of Example 5. The air permeability of Comparative Examples 1-6 was such that only Comparative Example 2 was less than 1 Gurley unit, but 5 / 6 of the comparative examples were 4.8 Gurley units or more. Therefore, it can be said that the air permeability of Examples 1-8 is lower than that of the comparative examples. That is, although there is a relationship with the diffusion coefficient, it is presumed that the air permeability is preferably a value of, for example, 1 Gurley unit or less.

[0152] The coating layer 43 is not necessarily required, and regardless of the material of the coating layer 43, it has been found that the coating layer 43 may be a non-metallic resin (polyvinyl alcohol, polyvinyl acetate) or a thickener (gum arabic). This indicates that the coating agent that forms the coating layer 43 may be any composition as long as it can penetrate into the micropores of the base sheet 42 and solidify within the micropores to block the micropores. Also, as in Examples 1-4, it has been found that the air permeability standard for the two-layer or one-layer wrapper 41 having the base sheet 42 and not having the base sheet 42A is less than 1 Gurley unit.

[0153] Regarding Comparative Example 6, an example in which NPNP1 is used as the base sheet 42 and P10000C is used as the base sheet 42A was described. Although the coating amount of the coating layer 43 is different, it is different from Example 5 in that the base sheet 42 used is different. It is assumed that NPNP1 contributes to increasing the diffusion coefficient and air permeability compared to the TP base paper. Therefore, it can be said that the selection of not only the inner base sheet 42A but also the outer base sheet 42 is important for the wrapper 41.
