Description

flavor producing articles

[0001] The present invention relates to flavored products.

[0002] Flavor product products composed of components such as a flavor generating segment having a flavor generating component, a mouthpiece segment, and a lining sheet around which these are wrapped are used in cigarettes (paper cigarettes), which have been used for many years, and in non-combustion heated flavor product products for electrically heated flavor generating systems that use electrical heating without combustion, which have recently attracted attention as cigarette substitutes. A variety of segments are used to compose the flavor product products, and one example is a front plug that is arranged upstream of the flavor generating segment (Patent Document 1).

[0003] Special Publication No. 2015-503336

[0004] Typically, the filler material for the tip plug is cellulose acetate tow or paper, the same as the filter material. Because these materials are the same white color as the filter material, some users may mistakenly insert the filter side (mouth end) of the tobacco stick into the heating chamber of the electrically heated flavor generating device. Therefore, the present invention provides a flavor product with a tip plug that makes it easy to identify the mouth end. The present invention also provides a flavor product that has a tip plug but gives the same appearance and impression as a conventional tobacco stick.

[0005] As a result of extensive research, the present inventors discovered that the above problems could be solved by making the filler material of the distal plug a specific color, and thus arrived at the present invention.

[0007] The present invention can provide a flavored product having a tip plug that makes it easy to distinguish the mouth end side. Furthermore, the present invention can provide a flavored product that has a tip plug but gives the same appearance as a conventional tobacco stick.

[0008] 1 is a schematic diagram of a flavored product according to an embodiment of the present invention.

[0009] Embodiments of the present invention will be described in detail below, but these descriptions are merely examples (representative examples) of embodiments of the present invention, and the present invention is not limited to these details as long as it does not deviate from the gist of the present invention. In this specification, a numerical range expressed using "to" means a range that includes the numerical values ​​before and after "to" as the lower and upper limits, and "A to B" means A or more and B or less. In addition, in this specification, the expression "A or B" may be read as "at least one selected from the group consisting of A and B." In addition, although multiple embodiments will be described in this specification, various conditions in each embodiment may be applied to each other to the extent applicable.

[0010] <Flavor product> A flavor product according to one embodiment of the present invention (also simply referred to as a "flavor product") is a flavor product comprising a tip plug segment, a flavor generating segment, a cooling segment, and a filter segment, wherein the tip plug segment includes a brown tip filler material.

[0011] By filling the flavor product according to one embodiment of the present invention with the brown tip filler, the end of the flavor product according to the present invention has a different appearance from the mouth end where the filter segment is located, allowing the user to easily insert the tip plug segment side into the heating chamber of the electrically heated flavor generating device. Furthermore, during manufacturing, both ends of the flavor product can be easily identified, facilitating packaging. Furthermore, because the brown tip filler has a similar appearance to the tobacco filler filled into the end of a conventional tobacco stick, the flavor product according to one embodiment of the present invention can have the same appearance as a conventional tobacco stick.

[0012] Hereinafter, a flavored product according to this embodiment will be described with reference to Figure 1, but this embodiment is not limited to this aspect. Although each embodiment is sometimes described using figures in this specification, the dimensions, materials, shapes, and relative positions of components described in each embodiment and shown in the figures are merely examples. For example, in this embodiment, a flavored product containing a tobacco filler as a flavor source will be described as an example of a flavored product, but the flavored product may not contain a tobacco filler and may contain other flavor components.

[0013] The rod-shaped flavor product 100 shown in Figure 1 is a flavor product having a tip plug segment 101, a flavor generating segment 102, a cooling segment 103, a filter segment 104, a first outer plug wrapper 105 that wraps the tip plug segment 101, the flavor generating segment 102, and the cooling segment 103, and a second outer plug wrapper 106 that wraps the cooling segment 103 and the filter segment 104, wherein the filter segment 104 includes a first filter segment 104A and a second filter segment 104B, and the first filter segment 104A, the second filter segment 104B, the cooling segment 103, the flavor generating segment 102, and the tip plug segment 101 are arranged coaxially adjacent to each other in this order in the axial direction (also referred to as the "longitudinal direction") of the flavor product 100, and an opening V is provided concentrically in the circumferential direction of the cooling segment 103. The opening V is usually a hole for promoting the inflow of air from the outside when the user inhales, and this inflow of air can lower the temperature of the components and air flowing in from the flavor generating segment 102.

[0014] The first filter segment 104A and the second filter segment 104B each have a first wrapper 107 wound around their circumferential outer surfaces. The first filter segment 104A further includes a second wrapper 108 wound inside the first wrapper 107, specifically the second wrapper 108 disposed on the circumferential outer surface of the first filter segment 104A, and a filter medium 109 disposed inside the second wrapper 108.

[0015] In the flavor product 100, components generated by heating the flavor generating segment 102 and the like are delivered to the user's mouth through the cooling segment 103 and the filter segment 104. Examples of components generated by heating include flavor components derived from flavorings, nicotine and tar derived from tobacco leaves, and aerosol components derived from the aerosol base material. In this specification, the aerosol base material refers to a base material for generating aerosols and is not generally used in cigarettes. In the case of cigarettes, flavor components generated by burning the flavorings contained in the flavor generating segment 102, tobacco leaves, and the like, are typically delivered to the user's mouth.

[0016] 1 , reference numeral 151 denotes a mouth end of the flavor product product 100 (filter segment 104). Reference numeral 152 denotes a tip end of the flavor product product 100 opposite to the mouth end 151. The tip plug segment 101 is disposed on the tip 152 side of the flavor product product 100.

[0017] As described above, the segment arrangement configuration of the flavored product 100 is not limited to the embodiment shown in Fig. 1 and may be any general embodiment. For example, in the embodiment shown in Fig. 1, the filter segment 104 includes two filter segments, a first filter segment 104A and a second filter segment 104B, but the flavored product 100 may include only a single filter segment.

[0018] The flavored product 100 preferably has a columnar shape that satisfies the requirement that the aspect ratio, defined as follows, is 1 or greater: aspect ratio = h / w, where w is the width of the base of the columnar body (herein, this is defined as the width of the base at the end (reference numeral 152) on the tip plug segment 101 side), and h is the height, and it is preferable that h ≥ w. In this specification, the major axis direction is defined as the direction indicated by h. Therefore, even if w ≥ h, the direction indicated by h will be referred to as the major axis direction for convenience. The shape of the base is not limited and may be a polygon, a rounded polygon, a circle, an ellipse, or the like, and the width w is the diameter if the base is a circle, the major axis if the base is an ellipse, or the diameter of the circumscribing circle or the major axis of the circumscribing ellipse if the base is a polygon or a rounded polygon.

[0019] The length h of the flavored product 100 in the major axis direction is not particularly limited and is, for example, usually 40 mm or more, preferably 45 mm or more, and more preferably 50 mm or more, and is usually 100 mm or less, preferably 90 mm or less, and more preferably 80 mm or less. The width w of the bottom surface of the flavored product 100 is not particularly limited and is, for example, usually 5 mm or more, and preferably 5.5 mm or more, and is usually 10 mm or less, preferably 9 mm or less, and more preferably 8 mm or less.

[0020] The airflow resistance in the longitudinal direction of each flavored product 100 is not particularly limited, but from the viewpoint of ease of smoking, it is usually 10 mmH ２ O or more, 20 mmH ２ It is preferable that the pressure is 30 mmH or more. ２ It is more preferable that the pressure is 100 mmH or more. ２ O or less, 80 mmH ２ It is preferable that the pressure is 60 mmH or less. ２It is more preferable that the airflow resistance is 0 or less. The airflow resistance is measured in accordance with the ISO standard method (ISO6565:2015) using, for example, a filter airflow resistance measuring device manufactured by Cerulean Co., Ltd. The airflow resistance refers to the air pressure difference between the first end face and the second end face when air is flowed at a predetermined air flow rate (17.5 cc / min) from one end face (first end face) to the other end face (second end face) in a state where air does not pass through the side faces of the flavored product 100. The unit is generally mmH. ２ The airflow resistance is represented by O. It is known that the relationship between the airflow resistance and the length of the flavor product 100 is proportional within a commonly used length range (5 to 200 mm), and if the length is doubled, the airflow resistance of the flavor product 100 also doubles.

[0021] [Tip Plug Segment] The flavored product 100 has a tip plug segment 101. The tip plug segment 101 includes a tip filler, which may be wrapped around a tip plug segment wrapper. The shape of the tip plug segment is not particularly limited and may be any known shape, for example, a cylindrical shape as shown in FIG. 1 . The length of the tip plug segment 101 in the longitudinal direction may be varied appropriately depending on the size of the product, but is typically 2.5 mm or more, preferably 3 mm or more, and more preferably 4 mm or more. Furthermore, the length is typically 30 mm or less, preferably 20 mm or less, more preferably 15 mm or less, and even more preferably 10 mm or less.

[0022] The end face porosity of the tip plug segment 101 is not particularly limited, but is typically 50% or more and 90% or less, preferably 60% or more and 85% or less, and more preferably 65% ​​or more and 80% or less. By setting the end face porosity within the above range, it is possible to achieve appropriate airflow resistance while maintaining the hardness of the tip plug segment 101. The end face porosity can be calculated as follows: (End face area of ​​tip plug segment) - (Area of ​​tip filling material) = (Area of ​​open space) (Area of ​​open space) / (End face area of ​​tip plug segment) = (End face porosity). Here, the end face area of ​​the tip plug segment is the area occupied by the tip plug segment when viewed from the longitudinal axis direction of the tip plug segment, excluding the thickness of the tip segment wrapper. For example, when the tip filling material is a sheet material, the area of ​​the tip filling material is the area obtained by multiplying the thickness of the sheet material by the width of the sheet material in the end face direction of the tip plug segment.

[0023] The airflow resistance of the tip plug segment 101 is not particularly limited, but is usually 0 mmH per 8 mm of length. ２ O or more, 80mmH ２ 0 or less, and 5 mmH ２ O or more, 70mmH ２ Preferably, it is 8 mmH or less. ２ O or more, 50mmH ２ 0 or less is more preferable, and 10 mmH ２ O or more, 25mmH ２ It is more preferably equal to or less than 0. The airflow resistance of the tip plug segment 101 can be measured by the same method as the method for measuring the airflow resistance of the flavored product 100 described above.

[0024] (Tip Filler) The tip filler is not particularly limited as long as it has a color that can be recognized as brown under natural light. In this specification, brown includes light brown, beige, brown, dark brown, and deep brown. The tip filler may be a color that meets the CIE 1976L ＊ a ＊ b ＊ L in color space ＊ The value is 31 to 56, and a ＊ The value is 1 to 19, and b ＊The L value is preferably 9 to 29. When the L value is within the above range, the tobacco stick exhibits a color that is generally recognized as brown. Therefore, the tobacco stick can have an appearance similar to that of conventional tobacco sticks. ＊ The range of the value is more preferably 32 to 53, and even more preferably 33 to 50. ＊ The range of the value is more preferably 5 to 18, and further preferably 9 to 14. ＊ The range of the value is more preferably 12 to 29, and even more preferably 15 to 28.

[0025] Also, CIE1976L ＊ a ＊ b ＊ In the color space, the color difference ΔE between the tip filler and the tobacco filler contained in the flavor generating segment described below is preferably 20 or less, more preferably 10 or less, even more preferably 5 or less, and particularly preferably 2.5 or less. By being in the above range, it is possible to give an appearance similar to that of a conventional tobacco stick, and to reduce the sense of incongruity at the boundary between the flavor generating segment and the tip plug segment.

[0026] CIE1976L ＊ a ＊ b ＊ L in color space ＊ Value, a ＊ value, b ＊ The color difference ΔE can be measured using a spectrophotometer. Specifically, a spectrophotometer (manufactured by X-Rite, product name: SpectroEye) is used. Measurement is performed by pressing the spectrophotometer against the sample under the conditions of light source D65, no light source filter, and a viewing angle of 2°. The color difference ΔE is the difference between the L ＊ Value, a ＊ value, b ＊ The difference between the values ​​is ΔL ＊ , Δa ＊ , Δb ＊ When the value is ΔE, it is calculated by the following formula: ΔE = √{(ΔL ＊ ) ２ + (Δa ＊ ) ２ + (Δb ＊ )２}

[0027] The tip filler is not particularly limited as long as it satisfies the above color conditions, and examples thereof include synthetic fibers, natural fibers, etc. Specific examples include those containing cellulose acetate fibers or pulp fibers. Synthetic fiber tow (also simply referred to as "tow") or a cylindrical sheet material such as paper can also be used. When paper is used as the tip filler, the type of paper is not particularly limited, and gathered paper, pleated paper, crimped paper, crepe paper, nonwoven fabric, and shredded paper can be used. The paper may be manufactured using either a wet or dry method, and can be selected as desired. Preferably, the tip filler does not contain tobacco shreds or a reconstituted tobacco sheet. According to the flavored product of this embodiment, even when the tip filler does not contain tobacco shreds or a reconstituted tobacco sheet, it can still have the same appearance as a conventional tobacco stick without a tip plug.

[0028] When a sheet material is used as the tip filler, the shape of the sheet material is not particularly limited, and examples thereof include a shape in which sheet materials having a wave-shaped structure with multiple valleys and ridges are assembled. By using such a shape, it is possible to give an appearance impression closer to that of conventional tobacco sticks. When a sheet material having a wave-shaped structure is used, the longitudinal direction of the valleys (or ridges) is arranged so that it is parallel to the longitudinal axis of the flavor product.

[0029] When a sheet material having the above-described corrugated structure is used as the sheet material constituting the tip filler, the average distance from trough to trough or from ridge to ridge of the above-described corrugations (also referred to as "average pitch") is not particularly limited, but is usually 0.5 mm or more, preferably 1.0 mm or more, and usually 5.0 mm or less, preferably 4.0 mm or less. Furthermore, the average depth of the troughs of the above-described corrugations (also referred to as "crimp depth") is not particularly limited, but is usually 0 mm or more, preferably 0.2 mm or more, more preferably 0.3 mm or more, and usually 1.2 mm or less, preferably 1.0 mm or less, more preferably 0.5 mm or less, and even more preferably 0.4 mm or less. By keeping the crimp depth within the above range, it is possible to impart an appearance closer to that of conventional tobacco sticks.

[0030] A sheet material having a corrugated structure can be produced by crimping a flat raw material sheet that does not have a corrugation, forming peaks and valleys. The thickness of the raw material sheet is not particularly limited, but is usually 20 μm or more, preferably 25 μm or more, more preferably 30 μm or more, and usually 140 μm or less, preferably 130 μm or less, more preferably 120 μm or less. The basis weight of the raw material sheet is not particularly limited, but is usually 20 gsm or more, preferably 25 gsm or more, and usually 120 gsm or less, preferably 80 gsm or less, more preferably 45 gsm or less. The basis weight can be adjusted by adjusting the pulp content and filler content used as raw materials for the sheet, or by adjusting the processing conditions of a wet paper machine.

[0031] The width of the raw material sheet is not particularly limited, but is usually 50 mm or more, preferably 100 mm or more, more preferably 160 mm or more, and 300 mm or less, preferably 250 mm or less, more preferably 240 mm or less. By setting the width of the raw material sheet within the above range, it is possible to give an appearance closer to that of conventional tobacco sticks. The width of the raw material sheet refers to the length in a direction perpendicular to the long axis direction in which peaks and valleys are continuously arranged in the sheet material having a corrugated structure. In other words, it is the length in a direction perpendicular to the direction corresponding to the long axis direction of the tip filler obtained by processing the sheet material having a corrugated structure.

[0032] The tip filler may contain a pigment or dye as appropriate to satisfy the above color requirements. The pigment is preferably an inorganic pigment, and iron oxide is more preferred. Examples of iron oxide include yellow iron oxide (iron oxyhydroxide (FeO(OH))), ferric hydroxide (Fe ２ (OH) ６ ), black iron oxide (iron oxide (Fe ３ O ４ ) and red iron oxide (red iron oxide, mainly consisting of ferric oxide). The tip filler may be free of pigments or dyes as long as it satisfies the above color requirements. Examples of such materials include unbleached pulp.

[0033] The tip filler may contain an aerosol base and / or flavoring, which may be contained in the flavor generating segment, as described below.

[0034] (Tip Plug Segment Wrapper) The configuration of the tip plug segment wrapper is not particularly limited and can be a common embodiment, such as cellulose fiber paper, and specifically, a wrapper containing pulp as the main component. Pulp may be produced from wood pulp such as softwood pulp or hardwood pulp, or may be produced by blending non-wood pulp commonly used in cigarette papers for tobacco products, such as flax pulp, sisal pulp, or esparto. Pulp types that can be used include chemical pulp produced by kraft cooking, acidic, neutral, or alkaline sulfite cooking, or soda cooking, ground pulp, chemi-ground pulp, and thermomechanical pulp.

[0035] The basis weight of the front plug segment wrapper base paper is not particularly limited, but is usually 20 gsm or more, preferably 25 gsm or more, and usually 65 gsm or less, preferably 50 gsm or less, and more preferably 45 gsm or less. The thickness of the front plug segment wrapper is not particularly limited, but from the viewpoints of rigidity, breathability, and ease of adjustment during papermaking, it is usually 10 μm or more, preferably 20 μm or more, more preferably 30 μm or more, and usually 100 μm or less, preferably 75 μm or less, and more preferably 50 μm or less.

[0036] The shape of the tip plug segment wrapper is not particularly limited, and examples thereof include a square or rectangle. In this case, the length of one side can be approximately 6 to 70 mm, and the length of the other side can be approximately 15 to 28 mm, preferably 22 to 24 mm, and more preferably approximately 23 mm. When wrapping the tip filler in a cylindrical shape with the tip plug segment wrapper, for example, the end of the wrapping paper in the w direction and the end on the opposite side are overlapped by approximately 2 mm and glued together to form a cylindrical paper tube shape in which the tip filler is filled. The size of the rectangular tip plug segment wrapper can be determined depending on the size of the finished tip plug segment 101.

[0037] In addition to the pulp, the tip plug segment wrapper may contain a filler. The filler content may be 10% by weight or more and less than 60% by weight, preferably 15% by weight or more and 45% by weight or less, and more preferably 25% by weight or more and 45% by weight or less, based on the total weight of the tip plug segment wrapper. Examples of fillers that can be used include calcium carbonate, titanium dioxide, and kaolin. However, calcium carbonate is preferred from the viewpoint of enhancing flavor and whiteness.

[0038] The air permeability of the tip plug segment wrapper is not particularly limited, but is usually 0 Coresta units or more and 30,000 Coresta units or less, and preferably more than 0 Coresta units and 10,000 Coresta units or less. The air permeability is a value measured in accordance with ISO 2965:2009, and is the value of the air permeability of an area of ​​1 cm per minute when the differential pressure between both sides of the paper is 1 kPa. ２ Flow rate of gas passing through (cm ３ 1 C.U. is expressed as cm under 1 kPa. ３ / (min cm ２ )

[0039] Various auxiliary agents other than the base paper and fillers may be added to the end plug segment wrapper. For example, a water resistance improver may be added to improve water resistance. Water resistance improvers include wet strength agents (WS agents) and sizing agents. Examples of wet strength agents include urea-formaldehyde resin, melamine-formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification degree of 90% or more. A paper strength agent may also be added as an auxiliary agent, such as polyacrylamide, cationic starch, oxidized starch, carboxymethyl cellulose, polyamide epichlorohydrin resin, or polyvinyl alcohol. In particular, it is known that the use of a very small amount of oxidized starch improves breathability (for example, JP 2017-218699 A).

[0040] The tip plug segment wrapper may be coated appropriately. Specifically, a coating agent may be added to at least one of its two surfaces, the front and back surfaces. The coating agent is not particularly limited, but a coating agent capable of forming a film on the surface of the paper and reducing liquid permeability is preferred. Examples of the coating agent include alginic acid or its salts (e.g., sodium salts), polysaccharides such as pectin, cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, and nitrocellulose, starch or its derivatives (e.g., ether derivatives such as carboxymethyl starch, hydroxyalkyl starch, and cationic starch, ester derivatives such as starch acetate, starch phosphate, and starch octenyl succinate), paraffin, polyolefin, polystyrene, silicone, resin, acrylic resin, and fluororesin.

[0041] The method for producing the tip plug segment wrapper is not particularly limited, and it can be produced by a known method, for example, by adjusting and uniforming the texture of beaten pulp using a paper machine. The type of paper machine is not particularly limited, and for example, a Fourdrinier paper machine, a cylinder paper machine, or a combined cylinder / short-cylinder paper machine can be used. If necessary, a wet strength agent can be added to impart water resistance to the tip plug segment wrapper, or a sizing agent can be added to adjust the printing quality of the tip plug segment wrapper. Furthermore, papermaking additives such as aluminum sulfate, various anionic, cationic, nonionic, or amphoteric retention aids, drainage aids, or paper strength aids, dyes, pH adjusters, antifoaming agents, pitch control agents, or slime control agents can be added.

[0042] The front plug segment wrapper may be subjected to calendering, which involves applying a press pressure using calender rollers. The method and conditions for the calendering are not particularly limited, and the calendering may be performed, for example, by the method and conditions described in International Publication No. 2008 / 072523. Calendering can increase the degree of beating of the front plug segment wrapper and decrease its air permeability.

[0043] [Flavor generating segment] The flavor product 100 has a flavor generating segment 102. The form of the flavor generating segment 102 is not particularly limited as long as it is a known form, but it is usually formed by wrapping a flavor source such as a tobacco filler with a flavor generating segment wrapper. The method for manufacturing the flavor generating segment 102 is also not particularly limited, and a known method or a combination of known methods can be applied. The form of the flavor source is not particularly limited, and in the case of a tobacco filler, known materials such as tobacco shreds or reconstituted tobacco sheets can be used. The tobacco filler is usually brown in color.

[0044] The tobacco filler may also contain an aerosol base. The aerosol base is a base that generates an aerosol when heated, and examples of such aerosol base include glycerin, propylene glycol, triacetin, 1,3-butanediol, or a mixture thereof. The content of the aerosol base in the tobacco filler is not particularly limited, and from the viewpoints of generating sufficient aerosol and imparting a good flavor, it is usually 5% by weight or more, preferably 10% by weight or more, and usually 50% by weight or less, and preferably 15% by weight or more and 25% by weight or less, relative to the total amount of the tobacco filler.

[0045] When shredded tobacco is used as the tobacco filler, the shredded tobacco material is not particularly limited, and known materials such as lamina or ribs can be used. Alternatively, dried tobacco leaves may be crushed to an average particle size of 20 μm or more and 200 μm or less to produce tobacco pulverized material, which is then homogenized and processed into a sheet (hereinafter simply referred to as a reconstituted tobacco sheet). Furthermore, a so-called strand type may be used, in which a reconstituted tobacco sheet having a length approximately equal to the longitudinal direction of the flavor generation segment 102 is shredded approximately parallel to the longitudinal direction of the flavor generation segment 102 and filled. The width of the shredded tobacco is preferably 0.5 mm or more and 2.0 mm or less. The content of dried tobacco leaves contained in the flavor generation segment 102 is not particularly limited, but may be 200 mg or more and 800 mg or less relative to the entire flavor generation segment, and preferably 250 mg or more and 600 mg or less. This range is particularly suitable for a flavor generation segment 102 having a circumference of 22 mm and a length of 20 mm.

[0046] The moisture content of the tobacco filler can be 10% by weight or more and 15% by weight or less, and preferably 11% by weight or more and 13% by weight or less, based on the total weight of the tobacco filler. This moisture content suppresses staining of the flavor generating segment wrapper, as described below, and improves the suitability for wrapping during the production of the flavor generating segment 102. There are no particular restrictions on the size or preparation method of the tobacco shreds contained in the tobacco filler. For example, dried tobacco leaves shredded to a width of 0.5 mm or more and 2.0 mm or less may be used. Furthermore, when using ground reconstituted tobacco sheets, dried tobacco leaves may be ground to an average particle size of approximately 20 μm to 200 μm, homogenized, and then processed into sheets, which may then be shredded to a width of 0.5 mm or more and 2.0 mm or less.

[0047] The tobacco filler may contain the above-mentioned aerosol base material. The type of the aerosol base material is not particularly limited, and extracts from various natural products and / or their constituent components can be selected depending on the application. The content of the aerosol base material in the tobacco filler is not particularly limited, and from the viewpoint of generating sufficient aerosol and imparting a good flavor, it is usually 5% by weight or more, preferably 10% by weight or more, and usually 50% by weight or less, preferably 15% by weight or more and 25% by weight or less, based on the total amount of the tobacco filler. The tobacco filler may also contain a flavoring.

[0048] Furthermore, the flavor generation segment 102 may have a fitting portion with a heater member or the like for heating the flavor product 100. The flavor generation segment 102 preferably has a columnar shape, and in this case, it is preferable that the aspect ratio, which is expressed as the height of the flavor generation segment 102 in the major axis direction relative to the width of the bottom surface of the flavor generation segment 102, is 1 or more. The shape of the bottom surface of the flavor generation segment 102 is not limited and may be a polygon, a rounded polygon, a circle, an ellipse, or the like, and the width is the diameter if the bottom surface is circular, the major axis if the bottom surface is elliptical, or the diameter of the circumscribing circle or the major axis of the circumscribing ellipse if the bottom surface is polygonal or rounded polygonal.

[0049] The length of the flavor generating segment 102 in the longitudinal direction can be varied depending on the size of the product, but is typically 5 mm or more, preferably 7 mm or more, more preferably 10 mm or more, and even more preferably 13 mm or more, and is typically 60 mm or less, preferably 50 mm or less, more preferably 25 mm or less, and even more preferably 20 mm or less. From the viewpoint of the amount of flavor delivered and, when an aerosol base is used, the aerosol temperature balance, the ratio of the length of the flavor generating segment 102 to the length h of the flavor product 100 is typically 10% or more, preferably 20% or more, more preferably 25% or more, and even more preferably 30% or more, and is typically 60% or less, preferably 50% or less, more preferably 45% or less, and even more preferably 40% or less.

[0050] (Flavor generating segment wrapper) The configuration of the flavor generating segment wrapper is not particularly limited, and may be the same as that of the end plug segment wrapper.

[0051] [Cooling Segment] The flavor product 100 includes a cooling segment 103. The cooling segment 103 is sandwiched adjacent to the flavor generating segment 102 and the filter segment 104. It is typically a rod-shaped member having a hollow (hollow) circumferential cross section, such as a cylindrical member, and is formed as a cavity. For example, a paper tube may be used. The cooling segment 103 may be provided with a circumferential and concentric opening V (also referred to as a "ventilation filter (Vf)" in the technical field). When an aerosol base is used in the flavor generating segment 102, heating the flavor generating segment 102 generates vapor containing the aerosol base and tobacco flavor components. The vapor liquefies as the temperature is reduced in the cooling segment, generating an aerosol. In particular, when the opening V is provided, the vapor is more likely to come into contact with external air and reduce in temperature. The opening V will be described in detail below.

[0052] The number of openings V in the cooling segment 103 is not particularly limited, and multiple openings V may be arranged at regular intervals around the circumferential direction of the cooling segment 103. By providing the openings V in the cooling segment 103, when the flavor product 100 is inhaled, low-temperature air flows into the cooling segment 103 from the outside, thereby lowering the temperature of the volatile components and air flowing in from the flavor generation segment 102. Furthermore, the vapor containing the aerosol base material or tobacco flavor components, etc., is cooled by the low-temperature air introduced into the cooling segment 103 through the openings V and condenses. This promotes aerosol generation and allows the size of the aerosol particles to be controlled. The cooling effect can also be increased by applying a polymer coating such as polyvinyl alcohol or a polysaccharide coating such as pectin to the inner surface of the paper tube, utilizing the heat of solution associated with the heat absorption and phase change of the coating. The airflow resistance of this cylindrical cooling segment is zero mmH. ２When the concentric openings V are treated as one opening group, the number of opening groups may be one or may be two or more.

[0053] The opening V in the cooling segment 103 is preferably located at a position 1 mm or more, and more preferably 2 mm or more, away from the boundary between the cooling segment 103 and the filter segment 104. This not only improves the cooling capacity of the cooling segment 103, but also suppresses retention of components generated by heating within the cooling segment 103, thereby improving the delivery amount of the components. The second outer plug wrapper 106 preferably has an opening V located directly above (overlapping vertically with) the opening V in the cooling segment 103. After the cooling segment 103 and the filter segment 104 are wrapped and connected with the second outer plug wrapper 106, a laser beam may be irradiated from above the second outer plug wrapper 106, penetrating the second outer plug wrapper 106 and the cooling segment 103, to form an opening.

[0054] The diameter of the openings V is not particularly limited, but is preferably 100 μm or more and 1000 μm or less, and more preferably 300 μm or more and 800 μm or less. The openings are preferably substantially circular or substantially elliptical, and in the case of a substantially elliptical opening, the diameter indicates the major axis.

[0055] The length of the cooling segment 103 in the longitudinal direction can be changed appropriately depending on the size of the product, but is usually 10 mm or more, preferably 15 mm or more, and usually 40 mm or less, preferably 35 mm or less, more preferably 30 mm or less, and most preferably 20 mm. By setting the length of the cooling segment 103 in the longitudinal direction to be equal to or greater than the above-mentioned lower limit, a sufficient cooling effect can be ensured to obtain a good flavor, and by setting it to be equal to or less than the above-mentioned upper limit, adhesion of the generated steam and aerosol to the inner wall of the cooling segment 103 can be suppressed.

[0056] When a cooling sheet or the like is filled in the cooling segment 103 for cooling, the total surface area of ​​the cooling segment 103 is not particularly limited, and is, for example, 150 mm ２ / mm or more, 1000mm ２ This surface area is the surface area per length (mm) of the cooling segment 103 in the airflow direction, and includes the surface area of ​​the cooling sheet or the like filled in the cooling segment. The total surface area of ​​the cooling segment 103 is 200 mm ２ / mm or more, and 250 mm ２ / mm or more is more preferable, while 600 mm ２ / mm or less, and ２ / mm or less is more preferable.

[0057] In a preferred embodiment, the cooling segment 103 may be formed by a thin sheet of material that is wrinkled to form channels, and then pleated, gathered, and folded. The more folds or pleats within a given volume of the element, the greater the total surface area of ​​the cooling segment 103.

[0058] The use of paper as a cooling sheet material is also desirable from the viewpoint of reducing environmental impact. The paper used as a cooling sheet material preferably has a basis weight of 30 to 100 gsm and a thickness of 20 to 100 μm. From the viewpoint of minimizing the removal of flavor components and aerosol base components in the cooling segment, the paper used as a cooling sheet material preferably has low air permeability, preferably 10 Coresta units or less. By applying a polymer coating such as polyvinyl alcohol or a polysaccharide coating such as pectin to the paper used as a cooling sheet material, the cooling effect can be increased by utilizing the heat of solution associated with the endothermic heat of the coating or phase change.

[0059] The thickness of the constituent material of the cooling segment 103 (in the case of a paper tube, the thickness of the paper tube) is not particularly limited, and may be, for example, 5 μm or more and 500 μm or less, or 10 μm or more and 250 μm or less.

[0060] [Filter Segment] The flavored product 100 has a filter segment 104. The filter segment 104 may be configured in any manner as long as it functions as a general filter, and may be composed of a single segment or two or more segments. When the filter segment 104 includes two or more segments, it may be configured to include, for example, a first filter segment 104A and a second filter segment 104B, as shown in FIG. 1 .

[0061] The filter segment 104 may be, for example, a synthetic fiber tow (also simply referred to as "tow") or a cylindrically shaped material such as paper. The shape of the filter segment 104 is not particularly limited and may be any known shape, such as a cylindrical shape as shown in the first filter segment 104A of FIG. 1 . The filter segment 104 may also have a section such as a cavity (e.g., a center hole) or recess, whose circumferential cross section is hollow (hollow), as shown in the second filter segment 104B of FIG. 1 . A filter segment having a center hole (also referred to as a "center hole segment") is typically positioned upstream of a segment having a filter medium (e.g., an acetate filter segment), preferably adjacent to the upstream cooling segment. This embodiment prevents unnecessary loss of the generated aerosol and improves the appearance of the flavored product 100.

[0062] The circumferential cross-sectional shape of the filter segment 104 is substantially circular, and the diameter of the circle can be varied as needed to suit the size of the product. However, it is typically 4.0 mm to 9.0 mm, preferably 4.5 mm to 8.5 mm, and more preferably 5.0 mm to 8.0 mm. If the cross-section is not circular, the above diameter refers to the diameter of a circle having the same area as the cross-section. The circumferential length of the circumferential cross-sectional shape of the filter segment 104 can be varied as needed to suit the size of the product. However, it is typically 14.0 mm to 27.0 mm, preferably 15.0 mm to 26.0 mm, and more preferably 16.0 mm to 25.0 mm. The overall axial length of the filter segment 104 can be varied as needed to suit the size of the product. However, it is typically 5 mm to 35 mm, and preferably 10.0 mm to 30.0 mm.

[0063] The shape and dimensions of the filter material can be adjusted as appropriate so that the shape and dimensions of the filter segment 104 fall within the above ranges.

[0064] The airflow resistance per 120 mm of the axial length of the filter segment 104 is not particularly limited, but is usually 40 mmH ２ O or more, 300mmH ２ O or less, 70 mmH ２ O or more, 280mmH ２ It is preferable that the pressure is 90 mmH or less. ２ O or more, 260mmH ２ It is more preferable that the airflow resistance of the filter segment 104 is equal to or less than 0. The airflow resistance of the filter segment 104 can be measured by the same method as the method for measuring the airflow resistance of the flavored product 100 described above.

[0065] The filter segment 104 may be a segment including a filter medium 109, as shown in first filter segment 104A in FIG.

[0066] The density of the filter medium 109 is not particularly limited, but is usually 0.10 g / cm ３ Above, 0.25g / cm ３or less, and 0.11 g / cm ３ Above, 0.24g / cm ３ It is preferable that the density is 0.12 g / cm or less. ３ Above, 0.23g / cm ３ It is more preferable that the density is equal to or less than 100. When the filter medium 109 contains an additive release container, which will be described later, this density does not include the additive release container.

[0067] The filter medium 109 may be formed in any known manner, including, for example, pulp fibers or cellulose acetate tow (cellulose acetate fibers) processed into a cylindrical shape. The single-fiber fineness and total fineness of these fibers are not particularly limited, but for a mouthpiece member with a circumference of 22 mm, the single-fiber fineness is preferably 5 to 20 g / 9000 m and the total fineness is preferably 12,000 to 30,000 g / 9000 m. Examples of the cross-sectional shape of the fibers include circular, elliptical, Y-shaped, I-shaped, and R-shaped. In the case of a filter filled with cellulose acetate tow, the cellulose acetate fibers may be solidified with a plasticizer (triacetin). Specifically, to improve filter hardness, triacetin may be added in an amount of 5 wt% or more and 10 wt% or less relative to the weight of the cellulose acetate tow. In addition, instead of the acetate filter, other alternative filters such as a paper filter filled with sheet-like pulp paper as a filter medium may be used.

[0068] The filter segment 104 can be manufactured by a known method. For example, when synthetic fibers such as cellulose acetate tow are used as the material for the filter medium 109, as shown in the first filter segment 104A in Fig. 1, the filter medium 109 can be manufactured by spinning a polymer solution containing a polymer and a solvent and then crimping the polymer solution. For example, the method described in WO 2013 / 067511 can be used.

[0069] The filter medium 109 may also contain a component such as a flavoring agent, separate from the additive release container described below. Examples of flavoring agents include menthol, spearmint, peppermint, fenugreek, clove, and medium-chain triglycerides (MCTs). The same flavoring agent as that contained in the flavor generating segment 102 may also be used, with menthol being preferred. These components may be used alone, or two or more may be used in any combination and in any ratio.

[0070] Activated carbon may be added to the filter medium 109. There are no particular limitations on the method for adding activated carbon to the filter medium of the filter segment 104, and the activated carbon may be added so that it is dispersed substantially uniformly in the filter medium to which the activated carbon is added.

[0071] The filter media 109 may comprise a crushable additive release container (eg, a capsule) that includes a crushable outer shell.

[0072] For increased strength and structural rigidity, the filter segment 104 may include a second wrapper 108 wrapped around the filter material, as shown in the first filter segment 104A of FIG. 1. The second wrapper 108 may include one or more rows of adhesive seams, without limitation. The adhesive may include a hot melt adhesive, which may further include polyvinyl alcohol.

[0073] When the filter is made up of two or more segments, it is preferred to provide a first wrapper 107 that wraps the two or more segments together, as shown in first filter segment 104A in FIG.

[0074] The materials for the first wrapper 107 and the second wrapper 108 (collectively referred to as the "first wrapper, etc.") are not particularly limited, and known materials can be used. They may also contain fillers such as calcium carbonate. The thickness of the first wrapper, etc., is not particularly limited, and is typically 20 μm to 140 μm, preferably 30 μm to 130 μm, and more preferably 30 μm to 120 μm. The basis weight of the first wrapper, etc., is not particularly limited, and is typically 20 gsm to 100 gsm, preferably 22 gsm to 95 gsm, and more preferably 23 gsm to 90 gsm. The first wrapper, etc., may or may not be coated; however, from the viewpoint of imparting functions other than strength and structural rigidity, it is preferable to coat it with a desired material.

[0075] The first wrapper 107 and the second wrapper 108 may be of different materials, thicknesses, basis weights, and air permeabilities.

[0076] When a center hole segment (second filter segment 104B in FIG. 1) is used as the filter segment 104, the center hole segment may be composed of a packed layer having one or more hollow portions and a wrapper (first wrapper or second wrapper) wrapped around the outer surface of the packed layer. The center hole segment functions to adjust the longitudinal length of the flavor product while increasing the strength of the mouthpiece segment. The packed layer can be, for example, a rod with an inner diameter of 1.0 mm or more and 5.0 mm or less, packed with cellulose acetate fibers at a high density and hardened by adding a plasticizer containing triacetin at a ratio of 6% by mass to 20% by mass relative to the mass of cellulose acetate. Because the packed layer has a high fiber packing density, during inhalation, air and aerosol flow only through the hollow portions, with almost no flow within the packed layer. Because the packed layer inside the center hole segment is a fiber packed layer, the feel from the outside during use is less likely to cause discomfort to the user. Alternatively, the center-hole segment may not have a wrapper and retain its shape through thermoforming.

[0077] The length ratio of the cooling segment 103 to the filter segment 104 in the longitudinal direction of the flavor product 100 (cooling segment 103:filter segment 104) is not particularly limited, but from the viewpoint of the delivery amount of flavor components, it is usually 0.60:1.40 to 1.40:0.60, and may be 0.80:1.20 to 1.20:0.80, 0.85:1.15 to 1.15:0.85, 0.90:1.10 to 1.10:0.90, or 0.95:1.05 to 1.05:0.95. By setting the length ratio of the cooling segment 103 to the filter segment 104 within the above range, it is possible to achieve a cooling effect, an effect of suppressing adhesion of generated steam and aerosol to the inner wall of the cooling segment, and an effect of presenting a good flavor by balancing the air volume and flavor adjusting function of the filter. In particular, if the cooling segment is made longer, the particle formation of aerosols and the like is promoted, resulting in a good flavor, but if it is too long, substances passing through may adhere to the inner wall.

[0078] [First Outer Plug Wrapper] The flavor product 100 has a first outer plug wrapper 105 that wraps the tip plug segment 101, the flavor generating segment 102, and the cooling segment 103. The first outer plug wrapper 105 is not particularly limited and can be of a general type. Specifically, it can be the same as the tip plug segment wrapper.

[0079] The opacity of the first outer plug wrapper is not particularly limited, but is typically 75% or more, preferably 80% or more, and more preferably 85% or more. The opacity of the overlapping portion of the front plug segment wrapper and the first outer plug wrapper is preferably 85% or more, and more preferably 90% or more. The upper limit of the opacity is not particularly limited, but can be less than 100%. The opacity of the overlapping portion of the flavor generating segment wrapper and the first outer plug wrapper is preferably 85% or more, and more preferably 90% or more. The upper limit of the opacity is not particularly limited, but can be less than 100%. Preferably, the opacity of the overlapping portion of the front plug segment wrapper and the first outer plug wrapper and the opacity of the overlapping portion of the flavor generating segment wrapper and the first outer plug wrapper are both 85% or more. By ensuring that the opacity of the tip plug segment wrapper, flavor generating segment wrapper, and first outer plug wrapper satisfies any of the above conditions, the sense of incongruity at the boundary between the flavor generating segment and the tip plug segment can be reduced when observing the flavor product from outside the first outer plug wrapper.

[0080] The opacity is a value measured in accordance with ISO 2471 using a whiteness / opacity measuring instrument (manufacturer: Murakami Color Research Institute, model number: WMS-1). The opacity is a value calculated by the formula: single sheet luminous reflectance coefficient (R0) / intrinsic luminous reflectance coefficient (R∞) × 100 (%). The intrinsic luminous reflectance coefficient (R∞) in this calculation formula is the intrinsic reflectance coefficient of whiteness when measured using a specified reflectometer and light source under spectral conditions of an effective wavelength of 457 nm and a half-width of 44 nm. The opacity of the portion where the tip plug segment wrapper and the first outer plug wrapper overlap is measured by regarding the state where the tip plug segment wrapper and the first outer plug wrapper overlap as one sheet. The same applies to the opacity of the portion where the flavor generating segment wrapper and the first outer plug wrapper overlap.

[0081] [Second Outer Plug Wrapper] The flavor product 100 has a second outer plug wrapper 106 that wraps the flavor generating segment 102 and the filter segment 104. The second outer plug wrapper 106 may partially overlap the first outer plug wrapper 105. The second outer plug wrapper 106 may also be located outside or inside the first outer plug wrapper 105. The second outer plug wrapper 106 is not particularly limited and may have a general form. Specifically, it may be the same as the end plug segment wrapper.

[0082] <Method for manufacturing flavor product> The method for manufacturing the above-mentioned flavor product 100 is not particularly limited, and a known method or a combination of known methods can be applied. For example, the flavor product can be manufactured by wrapping the tip plug segment 101, the flavor generation segment 102, and the cooling segment 103 with a first outer plug wrapper 105, and then wrapping the cooling segment 103 and the filter segment 104 with a second outer plug wrapper 106.

[0083] The flavor product 100 described above can be inserted into a heating chamber of an electrically heated flavor generating device (not shown) and heated to generate an aerosol containing components such as tobacco components. The heating temperature is typically between 150°C and 400°C. The end on the tip plug segment 101 side has a different appearance from the mouth end where the filter segment is located, allowing the user to easily insert the tip plug segment side into the heating chamber.

[0084] In the measurement of each property in this specification, unless otherwise specified, the measurement sample is kept in an environment similar to the measurement environment for 48 hours or more before the measurement. Furthermore, unless otherwise specified, the measurement temperature, measurement humidity, and measurement pressure are normal temperature (25±2°C), normal humidity (60±5% RH), and normal pressure (atmospheric pressure).

[0085] The present invention will be described in more detail below with reference to examples, but the present invention should not be construed as being limited to the following examples.

[0086] (Test Example 1) A tip plug segment according to Test Example 1 was produced by wrapping a colored cellulose acetate fiber with a tip plug segment wrapper to a circumference of 25 mm and cutting it to a length of 5 mm. The colored cellulose acetate fiber used had a filament denier of 5 and a total denier of 30,000. The fiber was colored by adding a pigment to the raw material before spinning. The tip plug segment wrapper used was paper with a basis weight of 36 gsm, a thickness of 43 μm, and an opacity of 78%. A cross section of the tip plug segment in the longitudinal direction was measured using a spectrophotometer (manufactured by X-Rite, product name: SpectroEye) to measure the CIE 1976L. ＊ a ＊ b ＊ L in color space ＊ Value, a ＊ value, b ＊ The values ​​were measured. The minimum patch size was 2 mm, and the actual measurement range was a circle with a diameter of 2 mm. Measurements were taken at three points on each of six samples, with the actual measurement range shifted, and the average value was calculated. The results are shown in Table 1.

[0087]

[0088] All of the samples shown in Table 1 had a brown appearance, and it was believed that when used as a tip plug segment, they could give an appearance similar to that of a conventional tobacco stick without a tip plug.

[0089] (Test Example 2) The surface of the following paper was measured using a spectrophotometer (manufactured by X-Rite, product name: SpectroEye) according to CIE 1976L. ＊ a ＊ b ＊ L in color space ＊ Value, a ＊ value, b ＊The values ​​were measured. Papers 1 to 4 contain pigment, Paper 5 contains unbleached pulp, and Paper 6 is a reconstituted tobacco sheet. The results are shown in Table 2. Paper 1 (colored paper): basis weight 33 gsm, thickness 50 μm Paper 2 (colored paper): basis weight 26 gsm, thickness 40 μm Paper 3 (colored paper): basis weight 26 gsm, thickness 43 μm Paper 4 (colored paper): basis weight 26 gsm, thickness 38 μm Paper 5 (colored paper): basis weight 27 gsm, thickness 46 μm Cast sheet: basis weight 150 gsm, thickness 155 μm, blended with 76% tobacco material, 6% pulp, 6% binder, and 6% glycerin

[0090]

[0091] Papers 1 to 6 are L ＊ The value is 31 to 56, and a ＊ The value is 1 to 19, and b ＊ The values ​​were 9 to 29, and the tobacco sticks had a brown appearance. When these were used as tip plug segments, it was thought that they could give an appearance similar to that of conventional tobacco sticks without tip plugs.

[0092] (Test Example 3) A 240 mm wide piece of paper 1 was wrinkled to a crimp depth of 0.4 mm, and then wrapped in a rod shape with a tip plug segment wrapper to produce a tip plug segment. The tip plug segment wrapper used was paper with a basis weight of 36 gsm, a thickness of 43 μm, and an opacity of 78%. The tip plug segment using Brown TP (hereinafter referred to as "Sample 1") and the tip plug segment according to Test Example 1 (hereinafter referred to as "Sample 2"), as well as conventional tobacco sticks, Stick A (for Mevius Rich Ploom X and Ploom S) and Stick B (Marlboro HeatSticks Smooth Regular), were measured for CIE 1976L using a spectrophotometer (manufactured by X-Rite, product name: SpectroEye). ＊ a ＊ b ＊ L in color space ＊ Value, a ＊ value, b ＊ Furthermore, the color difference ΔE of Sample 1 and Sample 2 relative to Stick A and Stick B was measured. Ａ and ΔEＢ The results are shown in Table 3.

[0093]

[0094] As shown in Table 3, Samples 1 and 2 had a color difference ΔE of 20 or less compared to the conventional tobacco sticks, Stick A and Stick B, and had a similar appearance impression.

[0095] A tip plug segment was prepared in the same manner as Sample 1, except that the width and crimp depth of Paper 1 were changed, and the difference in appearance from the end face of Stick A was evaluated according to the following criteria: A: Almost no difference B: Some difference C: Difference

[0096]

[0097] Samples A to F had a brown appearance, similar to that of Stick A, a conventional tobacco stick. However, the appearance of Sample A, which had a crimp depth of 0.1 mm, was relatively different from the end face of Stick A. On the other hand, the appearance of Samples C, D, and F, which had a width of 180 mm or more and a crimp depth of 0.3 mm or more, was almost indistinguishable from that of the end face of Stick A.
