Description

[Technical field]

[0001] The present invention relates to non-combustion heated tobacco and electrically heated tobacco products. [Background technology]

[0002] In recent years, electrically heated tobacco products consisting of non-combustion heated tobacco that is inserted into an electrically heated device for use have been developed as an alternative to cigarettes (Patent Document 1). Such non-combustion heated tobacco generally comprises a tobacco rod in which tobacco shreds and materials that produce flavor components are wrapped in cigarette paper, a mouthpiece for inhaling the components generated from the tobacco rod by heating, and tipping paper around which these are wrapped. Generally, in electrically heated tobacco products, a non-combustion heated tobacco is inserted into an electrically heated device, and then the heater member is turned on to heat the tobacco rod starting from the point of contact with the heater member, and the generated components are delivered to the user.

[0003] The delivery of components generated by heating is considered an important characteristic not only for electrically heated tobacco products but also for cigarettes, and has been widely studied. Patent Document 2 discloses a cigarette in which a volatile containing agent contained in a polysaccharide gel is added to a tobacco rod to increase the amount of volatile flavoring contained in the smoke at the first puff, prevent the volatile flavoring from seeping out during storage, and maintain a desired amount of volatile flavoring delivered when smoking after storage. Patent Document 3 discloses a cigarette that can reduce undesirable components produced by combustion and deliver a good flavor by adding an adsorbent or liquid absorbent to a filter arranged downstream of the tobacco rod.

[0005] The above-mentioned Patent Documents 1 and 2 disclose techniques for adjusting the amount of volatile components and achieving desired component delivery by adding specific materials to a tobacco rod or filter. Compared to such techniques for improving the delivery of components generated by heating from the perspective of materials contained in tobacco, there has been little research into techniques for improving the delivery of the components from the perspective of the structure of the material that constitutes the filter, and there is room for improvement. Furthermore, compared to cigarettes that involve combustion, electrically heated tobacco products are heated to a lower temperature during use and produce smaller amounts of components, so there is a particular demand for improvements in the delivery amount of components. Therefore, an objective of the present invention is to provide a non-combustion heated tobacco product and an electrically heated tobacco product that have an improved delivery amount of components generated by heating. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The following describes in detail the embodiments of the present invention, but these descriptions are merely examples (representative examples) of the embodiments of the present invention, and the present invention is not limited to these contents as long as they do not depart from the gist of the present invention. In addition, in this specification, when a numerical value or physical property value is enclosed before and after "~", the values ​​before and after the "~" are included. In addition, in this specification, "plurality" means two or more, unless otherwise specified.

[0011] <Non-combustion heated tobacco> A non-combustion heated tobacco product according to one embodiment of the present invention (also simply referred to as a "non-combustion heated tobacco product") is a rod-shaped non-combustion heated tobacco product having a tobacco rod portion and a mouthpiece portion, The mouthpiece portion includes a filter segment having a filter medium, The filter medium has a Y-shaped circumferential cross section and is made of fibers with a single fiber denier of 8 or more and 12 or less, in this non-combustion heated tobacco product. An example of a non-combustion heat-not-burn tobacco product according to an embodiment is shown in Fig. 1. Hereinafter, the non-combustion heat-not-burn tobacco product will be described with reference to Fig. 1.

[0012] 1 is a rod-shaped non-combustion heat-not-burn tobacco 10 including a tobacco rod portion 11, a mouthpiece portion 14, and a tipping paper 15 around which these are wrapped, the mouthpiece portion 14 including a cooling segment 12 and a filter segment 13 including a filter medium, the cooling segment 12 being sandwiched adjacent to the tobacco rod portion 11 and the filter segment 13 in the axial direction (also referred to as the "long axis direction") of the non-combustion heat-not-burn tobacco 10, and an opening V is provided concentrically in the circumferential direction of the cooling segment 12. The opening V is usually a hole for promoting the inflow of air from the outside when the user inhales, and the inflow of this air can lower the temperature of the components and air flowing in from the tobacco rod portion 11. In the non-combustion heat-not-burn tobacco 10, components generated by heating the tobacco rod portion 11 and the like are delivered to the user's mouth through the mouthpiece portion. 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 is a base material for generating an aerosol.

[0013] The non-combustion heating tobacco product 10 preferably has a columnar shape that satisfies an aspect ratio of 1 or more, as defined below. Aspect ratio=h / w w is the width of the bottom surface of the columnar body (in this specification, this is defined as the width of the bottom surface on the tobacco rod portion side), and h is the height, and it is preferable that h≧w. In this specification, the long 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 long axis direction for convenience. The shape of the bottom surface is not limited and may be a polygon, a rounded polygon, a circle, an ellipse, etc., and the width w is the diameter if the bottom surface is a circle, the major axis if the bottom surface is an ellipse, or the diameter of the circumscribing circle or the major axis of the circumscribing ellipse if the bottom surface is a polygon or a rounded polygon. The length h of the non-combustion heating tobacco product 10 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 columnar body of the non-combustion heating tobacco product 10 is not particularly limited, and is, for example, usually 5 mm or more, preferably 5.5 mm or more, and usually 10 mm or less, preferably 9 mm or less, and more preferably 8 mm or less. The ratio of the length of the cooling segment and the length of the filter segment in the longitudinal direction of the non-combustion heating tobacco (cooling segment:filter segment) is not particularly limited, but from the viewpoint of the delivery amount of flavoring, it is usually 0.60 ~ 1.40 :0.60~1.40 Preferably, the ratio is 0.80 to 1.20: 0.80 to 1.20, more preferably 0.85 to 1.15: 0.85 to 1.15, more preferably 0.90 to 1.10: 0.90 to 1.10, and further preferably 0.95 to 1.05: 0.95 to 1.05. By setting the ratio of the lengths of the cooling segment and the filter segment within the above range, it is possible to achieve a balance between the cooling effect, the effect of suppressing losses due to adhesion of the generated steam and aerosol to the inner wall of the cooling segment, and the effect of presenting a good flavor by achieving a good balance between the air volume and flavor adjustment function of the filter. In particular, if the cooling segment is long, the particulation of aerosols and the like is promoted, resulting in a good flavor, but if it is too long, the adhesion of the passing substances to the inner wall is increased. This occurs.

[0014] The airflow resistance in the longitudinal direction per non-combustion heated tobacco product 10 is not particularly limited, but from the standpoint of ease of smoking, it is usually 8 mmH2O or more, preferably 10 mmH2O or more, and more preferably 12 mmH2O or more, and is usually 100 mmH2O or less, preferably 80 mmH2O or less, and more preferably 60 mmH2O or less. The airflow resistance is measured according to 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 (17.5cc / 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 non-combustion heated tobacco 10. The unit is generally expressed in mmH2O. It is known that the relationship between the airflow resistance and the length of the non-combustion heated tobacco is proportional within the length range usually used (lengths of 5mm to 200mm), and if the length is doubled, the airflow resistance of the non-combustion heated tobacco doubles.

[0015] [Mouthpiece section] The mouthpiece portion 14 is equipped with a filter segment 13 having a filter medium, and is not particularly limited as long as the filter medium is composed of fibers having a Y-shaped circumferential cross section and a single fiber denier of 8 or more and 12 or less, and may be, for example, as shown in Fig. 1, equipped with a cooling segment 12 and a filter segment 13 including the above-mentioned filter medium, and configured such that the cooling segment 12 is sandwiched adjacent to the tobacco rod portion 11 and the filter segment 13 in the axial direction of the non-combustion heat-not-burn tobacco 10. The filter segment 13 and the cooling segment 12 will be described in detail below.

[0016] (Filter segment) The filter segment 13 includes a filter medium, and the filter medium is composed of fibers having a Y-shaped circumferential cross section and a single fiber denier of 8 or more and 12 or less, and is not particularly limited as long as it has a general filter function. Examples of general filter functions include adjusting the amount of air mixed in when inhaling aerosols, reducing flavor, and reducing nicotine and tar, but it is not necessary for the filter to have all of these functions. In addition, in electrically heated tobacco products, which tend to generate fewer components and have a lower tobacco filler filling rate compared to cigarette products, one of the important functions is to suppress the filtering function while preventing the tobacco filler from falling.

[0017] The shape of the filter segment 13 is not particularly limited, and any known shape can be adopted. Usually, the filter segment 13 can have a cylindrical shape, and can have the following forms.

[0018] The circumferential cross-sectional shape of the filter segment 13 is substantially circular, and the diameter of the circle can be appropriately changed according to the size of the product, but is usually 4.0 mm or more and 9.0 mm or less, preferably 4.5 mm or more and 8.5 mm or less, and more preferably 5.0 mm or more and 8.0 mm or less. If the circumferential cross-section is not circular, the above diameter is the diameter of a circle assumed to have the same area as the area of ​​the cross-section. The circumferential length of the circumferential cross-sectional shape of the filter segment 13 can be appropriately changed according to the size of the product, but is usually 14.0 mm or more and 27.0 mm or less, preferably 15.0 mm or more and 26.0 mm or less, and more preferably 16.0 mm or more and 25.0 mm or less. The length of the filter segment 13 in the major axis direction can be appropriately changed according to the size of the product, but is usually 15 mm or more and 35 mm or less, preferably 17.5 mm or more and 32.5 mm or less, and more preferably 20.0 mm or more and 30.0 mm or less. The shape and dimensions of the filter medium can be adjusted as appropriate so that the shape and dimensions of the filter segment 13 are within the above ranges, but the length in the longitudinal direction of the filter medium can be changed as appropriate according to the size of the product. From the viewpoint of obtaining the desired hardness, the length is usually 3 mm or more and 30 mm or less, preferably 5 mm or more and 20 mm or less, more preferably 8 mm or more and 18 mm or less, and even more preferably 10 mm or more and 15 mm or less.

[0019] The airflow resistance in the longitudinal direction of the filter segment 13 is not particularly limited, but from the viewpoint of ease of inhalation, it is usually 1.0 mmH2O / mm or more and 4.0 mmH2O / mm or less. In particular, when the filter medium has a flavor capsule described later, it is preferably 1.5 mmH2O / mm or more and 4.0 mmH2O / mm or less from the viewpoint of ease of inhalation. In this case, when the filter medium further contains a flavoring agent described later, particularly when it contains a crystalline substance such as menthol as a flavoring agent, it is more preferable that it is 2.5 mmH2O / mm or more and 3.6 mmH2O / mm or less, while when it does not contain a flavoring agent, it is more preferable that it is 1.9 mmH2O / mm or more and 3.0 mmH2O / mm or less. In addition, when the filter medium does not have a flavoring capsule described later, it is preferably 1.3 mmH2O / mm or more and 2.4 mmH2O / mm or less from the viewpoint of ease of inhalation, regardless of whether it contains a flavoring agent or not. These conditions for airflow resistance can also be applied as conditions for airflow resistance in the airflow direction of the filter medium. The airflow resistance is measured according to the ISO standard method (ISO6565), for example, using a filter airflow resistance measuring device manufactured by Cerulean Co., Ltd. The airflow resistance of the filter segment 13 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 face of the filter segment 13. The unit is generally expressed in mmH2O. It is known that the relationship between the airflow resistance of the filter segment 13 and the length of the filter segment 13 is proportional within the length range usually used (lengths of 5 mm to 200 mm), and if the length is doubled, the airflow resistance of the filter segment 13 doubles.

[0020] Furthermore, the filter segment 13 may be, for example, a plain filter including a single filter segment, or a multi-segment filter including a plurality of filter segments, such as a dual filter or triple filter.

[0021] The filter segment 13 can be produced by a known method, for example, when a synthetic fiber such as cellulose acetate tow is used as the material of the filter medium, the filter segment 13 can be produced by a method of spinning a polymer solution containing a polymer and a solvent and crimping the polymer solution. For example, the method described in International Publication No. 2013 / 067511 can be used as the method. In manufacturing the filter segment 13, the adjustment of the airflow resistance and the addition of additives (known adsorbents and flavors (eg, menthol), granular activated carbon, flavor retention materials, etc.) to the filter medium can be appropriately designed.

[0022] The filter medium constituting the filter segment 13 is not particularly limited as long as it is composed of fibers having a Y-shaped circumferential cross section and a single fiber denier of 8 or more and 12 or less. For example, a tow such as cellulose acetate tow composed of fibers having a Y-shaped circumferential cross section processed into a cylindrical shape can be used. The circumferential cross section of the fibers constituting the tow has a Y-shape. When a tow having a Y-shape is used, the fiber shape is more complex than when a tow having a general fiber shape such as a circular shape is used, so that a filter segment having an excellent delivery amount is more likely to be obtained. In particular, a filter segment having a high component delivery amount and a desired hardness can be produced with a small amount of use, that is, while keeping costs down. From the viewpoint of improving the delivery amount of the components generated by heating, the single fiber denier (g / 9000m) of the fiber is not particularly limited as long as it is 8 or more and 12 or less, and may be 9 or more and 11 or less. If the single fiber denier of the fiber is below the above range, the structure of the fibers constituting the filter medium becomes too dense, so the delivery amount of the components decreases, and if it exceeds the above range, the structure of the fibers constituting the filter medium becomes too sparse, so sufficient hardness cannot be obtained. The total fiber denier (g / 9000m) of the fiber is not particularly limited, but from the viewpoint of improving the delivery amount of the components generated by heating, the total fiber denier may be 12000 or more and 35000 or less, and is preferably 15000 or more and 30000 or less. These single fiber denier and total fiber denier are particularly preferred when the circumference of the mouthpiece part is 22 mm. In the case of a filter filled with fibers, triacetin may be added at 5% by weight or more and 10% by weight or less to the total fiber weight in order to improve the filter hardness. The method for producing a fiber with a Y-shaped circumferential cross section is not particularly limited, but for example, in the case of acetate fiber, acetate flakes (cellulose acetate) are produced through acetylation of pulp raw material, and then the acetate flakes are dissolved in acetone (dope) in a dissolver and spun to produce a fibrous bundle, and in this spinning process, the shape of the nozzle die can be changed to make the circumferential cross section Y-shaped, and the diameter of the nozzle hole can be changed to change the fiber thickness (filament denier). Then, the total denier is determined according to the required air resistance, and the number of bundled yarns (total denier / filament denier) is determined accordingly, and the spun acetate fiber is spun using the required number of spinning chambers, and the spun and bundled acetate fiber is given a uniform wave shape (crimp) in a crimper, and the tow flowing in a ribbon shape can be layered and packaged in a packing machine while being twisted.

[0023] The density of the filter medium (particularly when the filter medium contains a flavor capsule described below, the density excluding the flavor capsule) is not particularly limited, but is usually 0.09 g / cm from the viewpoint of obtaining a desired hardness. 3 More than 0.25g / cm 3 Less than or equal to 0.09 g / cm 3 More than 0.20g / cm 3 It is preferable that the concentration is 0.09 g / cm or less. 3 More than 0.14g / cm 3 More preferably, it is 0.11 g / cm or less. 3 More than 0.14g / cm 3 It is even more preferable that:

[0024] The compression change rate P of the filter medium represented by the following formula (1) is one of the indicators of hardness, and is not particularly limited, but from the viewpoint of obtaining the desired hardness, it is usually 85% or more and 98% or less, preferably 88% or more and 95% or less, and more preferably 90% or more and 93% or less. The method for measuring this compression change rate P is not particularly limited, but it can be measured using, for example, SODIM-H Hardness module manufactured by Sodim SAS, and the numerical value can be adjusted by changing the density or material of the filter medium. P = (D1 × 100) / D2 (1) P(%): Compression change rate D1 (mm): The diameter of the filter medium in the compressed direction after compressing it under conditions of a compressive load of 3 N / mm per unit length in the longitudinal direction and a compression time of 10 seconds so that the filter medium deforms in a direction perpendicular to the air flow direction (in the case of a cylindrical shape, the circumferential direction). D2 (mm): Average diameter of the filter medium before compression Furthermore, since the compression change rate is one of the indices representing the hardness of a filter medium, in this specification the compression change rate is also referred to as "hardness".

[0025] In addition, the filter media is flavored separately from the flavor capsules described below. Agent For example, the flavoring agent may be menthol, spearmint, peppermint, fenugreek, clove, or medium-chain triglyceride (MCT), with menthol being preferred. These ingredients may be used alone or in any combination of two or more kinds in any ratio. The content of the flavoring agent (particularly menthol) in the filter medium (excluding the flavoring agent in the flavor capsule described below) is not particularly limited, and is usually 0.5% by weight or more and 15% by weight or less, and preferably 3% by weight or more and 10% by weight or less. 5 weight% or more, 10 It is more preferable that the content is 10% by weight or less.

[0026] The filter medium may have a crushable additive release container (e.g., flavor capsule) disposed therein, the container comprising a crushable outer shell such as gelatin. The flavor capsule (also referred to as "additive release container" in the art) may have any known form, for example, a crushable additive release container comprising a crushable outer shell such as gelatin. In this case, when the flavor capsule is broken by the tobacco product user before, during, or after use, it releases a liquid or substance (usually a flavoring agent) contained in the flavor capsule, which is then transferred to tobacco smoke during use of the tobacco product, and transferred to the surrounding environment after use. The form of the flavor capsule is not particularly limited, and may be, for example, an easily breakable flavor capsule, and is preferably spherical in shape. The additive contained in the flavor capsule may contain any of the additives described above, and is preferably a flavoring agent or activated carbon. In addition, one or more materials that help filter smoke may be added as additives. The form of the additive is not particularly limited, and is usually a liquid or solid The use of capsules containing additives is well known in the art. Breakable flavor capsules and methods for their manufacture are well known in the art. The flavoring agent may be, for example, menthol, spearmint, peppermint, fenugreek, clove, or medium chain triglycerides (MCT), etc. The flavoring agent may be menthol, or menthol, etc., or a combination thereof. When a fragrance capsule is used, if the single fiber denier of the fibers constituting the above-mentioned filter medium exceeds the upper limit of the above-mentioned range, the ingredients released from the fragrance capsule will not spread sufficiently onto the filter, and if it is below the lower limit, the spread of the ingredients onto the filter will be promoted too much, so that the amount of ingredient delivery will be excessively suppressed.

[0027] From the viewpoint of improving strength and structural rigidity, the filter segment 13 may be provided with a wrapper (filter plug wrapper) for wrapping the above-mentioned filter medium and the like. The form of the wrapper is not particularly limited, and may include one or more rows of seams containing adhesive. The adhesive may include a hot melt adhesive, and the hot melt adhesive may further include polyvinyl alcohol. In addition, when the filter segment is composed of two or more segments, it is preferable that the wrapper wraps these two or more segments together. The material of the wrapper is not particularly limited, and any known material can be used, which may contain a filler such as calcium carbonate. The thickness of the wrapper is not particularly limited, and is usually 20 μm or more and 140 μm or less, preferably 30 μm or more and 130 μm or less, and more preferably 30 μm or more and 120 μm or less. The basis weight of the roll is not particularly limited, and is usually from 20 gsm to 100 gsm, preferably from 22 gsm to 95 gsm, and more preferably from 23 gsm to 90 gsm. Furthermore, the wrapper may be either coated or uncoated, but is preferably coated with a desired material from the standpoint of imparting functions other than strength and structural rigidity.

[0028] The filter segment 13 may further include a center hole segment having one or more hollow portions. The center hole segment is usually disposed closer to the cooling segment than the filter medium, and is preferably disposed adjacent to the cooling segment.

[0029] The center hole segment is composed of a filling layer having one or more hollow parts and an inner plug wrapper (inner wrapping paper) covering the filling layer. For example, the center hole segment is composed of a filling layer having a hollow part and an inner plug wrapper covering the filling layer. The center hole segment has a function of increasing the strength of the mouthpiece part. The filling layer can be, for example, a rod having an inner diameter of φ1.0 mm or more and φ5.0 mm or less, which is densely packed with cellulose acetate fibers and hardened by adding a plasticizer containing triacetin in an amount of 6 mass% or more and 20 mass% or less relative to the mass of cellulose acetate. Since the filling layer has a high fiber packing density, air and aerosol flow only through the hollow parts during inhalation and hardly flow inside the filling layer. Since the filling layer inside the center hole segment is a fiber packed layer, the touch from the outside during use rarely causes discomfort to the user. The center hole segment may not have an inner plug wrapper and its shape may be maintained by thermoforming.

[0030] The center hole segment and the filter medium may be connected, for example, by an outer plug wrapper (outer wrapping paper). The outer plug wrapper may be, for example, a cylindrical paper. The tobacco rod portion 11, the cooling segment 12, and the connected center hole segment and filter medium may be connected, for example, by a mouthpiece lining paper. These connections can be made, for example, by applying a glue such as a vinyl acetate glue to the inner surface of the mouthpiece lining paper, and then inserting and winding the tobacco rod portion 11, the cooling segment 12, and the connected center hole segment and filter medium. These may be connected in multiple separate passes using multiple lining papers.

[0031] (Cooling segment) The cooling segment 12 is sandwiched adjacent to the tobacco rod portion and the filter segment, and is usually a rod-shaped member provided with a cavity such that the cross section in the circumferential direction of the cylinder or the like is hollow (hollow). The cooling segment 12 may be provided with openings V (also referred to in the art as "ventilation filters (Vf)") in the circumferential direction and concentrically therewith. When an aerosol base material is used in the tobacco rod portion, vapor containing the aerosol base material and tobacco flavor components generated by heating the tobacco rod comes into contact with air from the outside and is cooled, thereby liquefying the vapor, thereby accelerating the generation of the aerosol. Furthermore, when the concentrically arranged holes V are treated as one hole group, the hole group may be one or may be two or more. When there are two or more hole groups, from the viewpoint of improving the delivery amount of the component generated by heating, it is preferable that no hole group is provided in a region less than 4 mm from the boundary between the cooling segment and the filter segment toward the cooling segment. Furthermore, when the non-combustion heat-not-burn tobacco 10 is formed by wrapping the tobacco rod portion 11, the cooling segment 12, and the filter segment 13 with tipping paper 15, it is preferable that the tipping paper 15 has an opening immediately above the opening V provided in the cooling segment 12. When producing such a non-combustion heat-not-burn tobacco 10, a tipping paper 15 having an opening that overlaps with the opening V may be prepared and wrapped, but from the viewpoint of ease of production, it is preferable to produce the non-combustion heat-not-burn tobacco 10 using a cooling segment 12 that does not have an opening V, and then to open a hole that penetrates both the cooling segment 12 and the tipping paper 15 at the same time.

[0032] From the viewpoint of improving the delivery amount of the component generated by heating, the region in which the opening V exists is preferably a region of 4 mm or more in the direction from the boundary between the cooling segment 12 and the filter segment 13 toward the cooling segment, more preferably a region of 4.5 mm or more, even more preferably a region of 5 mm or more, and particularly preferably a region of 5.5 mm or more; from the viewpoint of ensuring the cooling function, it is preferably a region of 15 mm or less, more preferably a region of 10 mm or less, and even more preferably a region of 7 mm or less.

The height of the tobacco filler constituting the tobacco rod portion 11 is preferably about 10 to 70 mm, and the width is preferably about 4 to 9 mm.

[0039] The length of the tobacco rod portion 11 in the major axis direction can be changed appropriately according to the size of the product, but is usually 10 mm or more, preferably 12 mm or more, more preferably 15 mm or more, and even more preferably 18 mm or more, and is usually 70 mm or less, preferably 50 mm or less, more preferably 30 mm or less, and even more preferably 25 mm or less.

[0040] (Scrolling paper) The composition of the cigarette paper is not particularly limited and may be a common embodiment, for example, a cigarette paper mainly composed of pulp. The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing with non-wood pulp generally used in cigarette papers for tobacco products, such as flax pulp, hemp pulp, sisal pulp, or esparto. The types of pulp that can be used include chemical pulp produced by the kraft cooking method, acidic, neutral or alkaline sulfite cooking method, or soda salt cooking method, ground pulp, chemi-ground pulp, and thermomechanical pulp.

[0041] The above pulp is used to prepare cigarette paper by adjusting and homogenizing the texture during the papermaking process using a Fourdrinier papermaking machine, a cylinder papermaking machine, a combined cylinder and roll papermaking machine, etc. If necessary, a wet strength agent may be added to impart water resistance to the cigarette paper, or a sizing agent may be added to adjust the printing condition of the cigarette paper. Furthermore, papermaking additives such as aluminum sulfate, various anionic, cationic, nonionic, or amphoteric retention aids, drainage aids, or paper strength aids, dyes, pH adjusters, defoamers, pitch control agents, or slime control agents may be added.

[0042] The basis weight of the cigarette paper is, for example, usually 20 gsm or more, preferably 25 gsm or more, whereas the basis weight is usually 65 gsm or less, preferably 50 gsm or less, more preferably 45 gsm or less. The thickness of the cigarette paper having the above-mentioned characteristics is not particularly limited, and from the viewpoints of rigidity, breathability, and ease of adjustment during papermaking, it is usually 10 μm or more, preferably 20 μm or more, and more preferably 30 μm or more, and is usually 100 μm or less, preferably 75 μm or less, and more preferably 50 μm or less. The shape of the cigarette paper for the non-combustion heating tobacco can be, for example, square or rectangular. When used as cigarette paper for wrapping a tobacco filler (to produce a tobacco rod portion), the length of one side can be about 12 to 70 mm, and the length of the other side can be 15 to 28 mm, with the other side preferably having a length of 22 to 24 mm, and more preferably having a length of about 23 mm. When wrapping a tobacco filler in cigarette paper in a cylindrical shape, for example, the end of the cigarette paper in the w direction and the end on the opposite side are overlapped by about 2 mm and glued together to form a cylindrical paper tube shape in which the tobacco filler is filled. The size of the rectangular cigarette paper can be determined depending on the size of the completed tobacco rod portion 11. When the tobacco rod portion 11 and another member adjacent to the tobacco rod portion 11 are connected and wound together, such as with tipping paper, the length of one side may be 20 to 60 mm, and the length of the other side may be 15 to 28 mm.

[0043] In addition to the pulp, the cigarette paper may contain a filler, the content of which 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, based on the total weight of the cigarette paper. In the cigarette paper, within the preferred range of basis weight (25 gsm or more and 45 gsm or less), the filler content is preferably 15% by weight or more and 45% by weight or less. Furthermore, when the basis weight is 25 gsm or more and 35 gsm or less, the filler is preferably 15% by weight or more and 45% by weight or less, and when the basis weight is more than 35 gsm and 45 gsm or less, the filler is preferably 25% by weight or more and 45% by weight or less. As the filler, calcium carbonate, titanium dioxide, kaolin, or the like can be used, but it is preferable to use calcium carbonate from the viewpoint of enhancing flavor and whiteness.

[0044] Various auxiliaries other than the base paper and fillers may be added to the cigarette paper. For example, a water resistance improver may be added to improve water resistance. The water resistance improver includes a wet strength agent (WS agent) and a sizing agent. Examples of the wet strength agent include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. Examples of the sizing agent include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), highly saponified polyvinyl alcohol with a saponification degree of 90% or more, etc. As an auxiliary, a paper strength agent may be added, for example, polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, etc. In particular, it is known that the use of a very small amount of oxidized starch improves the air permeability (JP 2017-218699 A). The wrapping paper may also be appropriately coated.

[0045] A coating agent may be added to at least one of the two surfaces of the wrapper paper, the front and back surfaces. There are no particular limitations on the coating agent, but a coating agent capable of forming a film on the surface of the paper and reducing the permeability of liquids is preferred. Examples of the coating agent include alginic acid or a salt thereof (e.g., a sodium salt), a polysaccharide such as pectin, a cellulose derivative such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, or nitrocellulose, or starch or a derivative thereof (e.g., an ether derivative such as carboxymethyl starch, hydroxyalkyl starch, or cationic starch, an ester derivative such as starch acetate, starch phosphate, or starch octenyl succinate).

[0046] [Tip paper] The configuration of the tipping paper 15 is not particularly limited and may be a general embodiment, for example, one containing pulp as the main component. The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing non-wood pulp generally used for cigarette papers for tobacco articles, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in combination in any ratio. Furthermore, the tipping paper 15 may be made up of one sheet, but may also be made up of multiple or more sheets. As the form of pulp, chemical pulp by the kraft cooking method, acidic, neutral or alkaline sulfite cooking method, soda salt cooking method or the like, ground pulp, chemi-ground pulp, thermomechanical pulp, or the like can be used. The tipping paper 15 may be produced by the production method described below, or a commercially available product may be used. The shape of the tipping paper 15 is not particularly limited and can be, for example, square or rectangular.

[0047] The basis weight of the tipping paper 15 is not particularly limited, but is usually 32 gsm or more and 40 gsm or less, preferably 33 gsm or more and 39 gsm or less, and more preferably 34 gsm or more and 38 gsm or less. The air permeability of the tipping paper 15 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 Coresta Unit (1 Coresta Unit, 1 C.U.) is cm at 1 kPa. 3 / (min cm2).

[0048] The tip paper 15 may contain a filler other than the above pulp, examples of which include metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide, titanium dioxide, and aluminum oxide, metal sulfates such as barium sulfate and calcium sulfate, metal sulfides such as zinc sulfide, quartz, kaolin, talc, diatomaceous earth, and gypsum, and it is particularly preferable that the tip paper 15 contains calcium carbonate from the viewpoints of improving whiteness and opacity and increasing the heating rate. Moreover, these fillers may be used alone or in combination of two or more kinds.

[0049] In addition to the above pulp and filler, the tip paper 15 may contain various auxiliaries, for example, a water resistance improver to improve the water resistance. The water resistance improver includes a wet strength agent (WS agent) and a sizing agent. Examples of the wet strength agent include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. Examples of the sizing agent include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), highly saponified polyvinyl alcohol with a saponification degree of 90% or more, etc.

[0050] A coating agent may be added to at least one of the two surfaces, the front and back surfaces, of the tipping paper 15. There are no particular limitations on the coating agent, but a coating agent that can form a film on the surface of the paper and reduce liquid permeability is preferred.

[0051] The configuration of the non-combustion heated tobacco product according to this embodiment can be used in an electrically heated tobacco product, which will be described later, but can also be applied to cigarettes (paper cigarettes) that involve combustion.

[0052] [Manufacturing method of non-combustion heated tobacco] The method for producing the above-mentioned non-combustion heating tobacco is not particularly limited, and any known method can be applied. For example, the tobacco rod portion and the mouthpiece portion can be wrapped in tipping paper to produce the tobacco.

[0053] <Electrically heated tobacco products> An electrically heated tobacco product according to another embodiment of the present invention (also simply referred to as an "electrically heated tobacco product") is an electrically heated tobacco product comprising an electrically heated device including a heater element, a battery unit that serves as a power source for the heater element, and a control unit for controlling the heater element, and the above-mentioned non-combustion heated tobacco inserted so as to be in contact with the heater element. The electrically heated tobacco product may be configured to heat the outer peripheral surface of a non-combustion heated tobacco product 10 as shown in Fig. 2, or may be configured to heat the tobacco rod portion 11 of a non-combustion heated tobacco product 10 from the inside as shown in Fig. 3. The electrically heated device 20 shown in Figs. 2 and 3 is provided with an air introduction hole, but this is not shown here. The electrically heated tobacco product 30 will be described below with reference to Fig. 3. Note that for the non-combustion heated tobacco product 10 in Figs. 2 and 3, some of the reference symbols representing the components shown in Figs. 2 and 3 will be omitted. The electrically heated tobacco product 30 is used by inserting the non-combustion heated tobacco product 10 described above into contact with the heater member 21 arranged inside the electrically heated device 20. The electrically heated device 20 has a battery unit 22 and a control unit 23 inside a body 24 made of, for example, resin. When the non-combustion heated tobacco 10 is inserted into the electrically heated device 20, the outer surface of the tobacco rod portion 11 comes into contact with the heater member 21 of the electrically heated device 20, and eventually the entire outer surface of the tobacco rod portion 11 and part of the outer surface of the tipping paper come into contact with the heater member 21. The heater member 21 of the electrically heated device 20 generates heat under the control of the control unit 23. The heat is transmitted to the tobacco rod portion 11 of the non-combustion heat-not-burn tobacco 10, causing the aerosol base material, flavor components, and the like contained in the tobacco filler of the tobacco rod portion 11 to volatilize.

[0054] The heater member 21 may be, for example, a sheet heater, a flat heater, or a cylindrical heater. The sheet heater is a flexible sheet-shaped heater, and examples thereof include a heater including a film (thickness: about 20 μm to 225 μm) of a heat-resistant polymer such as polyimide. The flat heater is a rigid flat heater (thickness: about 200 μm to 500 μm), and examples thereof include a heater having a resistance circuit on a flat substrate and using that part as a heat generating part. The cylindrical heater is a hollow or solid cylindrical heater (thickness: about 200 μm to 500 μm), and examples thereof include a heater having a resistance circuit on the outer circumferential surface of a metal cylinder and using that part as a heat generating part. In addition, examples thereof include a rod-shaped heater or a cone-shaped heater made of metal or the like having a resistance circuit inside and using that part as a heat generating part. The circumferential cross-sectional shape of the cylindrical heater may be a circle, an ellipse, a polygon, or a rounded polygon. In the case of an embodiment in which the outer peripheral surface of the non-combustion heat-not-burn tobacco 10 is heated as shown in Fig. 2, the above-mentioned sheet-shaped heater, flat plate-shaped heater, and cylindrical heater can be used. On the other hand, in the case of an embodiment in which the tobacco rod portion 11 of the non-combustion heat-not-burn tobacco 10 is heated from the inside as shown in Fig. 3, the above-mentioned flat plate-shaped heater, columnar heater, and cone-shaped heater can be used. The length of the heater member 21 in the major axis direction can be within the range of L±5.0 mm, where the length of the tobacco rod portion 11 in the major axis direction is L mm. From the viewpoint of aerosol delivery, that is, sufficient heat transfer to the tobacco rod portion 11 and sufficient volatilization of the aerosol base material and flavor components contained in the tobacco filler, the length of the heater member 21 in the major axis direction is preferably L mm or more, and from the viewpoint of suppressing the generation of components that have an undesirable effect on the flavor, the length of the heater member 21 in the major axis direction is preferably L+0.5 mm or less, L+1.0 mm or less, L+1.5 mm or less, L+2.0 mm or less, L+2.5 mm or less, L+3.0 mm or less, L+3.5 mm or less, L+4.0 mm or less, L+4.5 mm or less, or L+5.0 mm or less.

[0055] The heating intensity, such as the heating time and heating temperature of the non-combustion heated tobacco product 10 by the heater member 21, can be preset for each electrically heated tobacco product 30. For example, by performing pre-heating for a certain period of time after inserting the non-combustion heated tobacco product 10 into the electrically heated device 20, the temperature of the outer circumferential surface of the portion of the non-combustion heated tobacco product 10 inserted into the electrically heated device 20 reaches X (°C), and thereafter, the temperature can be preset to be maintained at a constant temperature of X (°C) or less. From the viewpoint of the delivery amount of components generated by heating, the above X (°C) is preferably 80°C or more and 400°C or less. Specifically, it can be 80°C, 90°C, 100°C, 110°C, 120°C, 130°C, 140°C, 150°C, 160°C, 170°C, 180°C, 190°C, 200°C, 210°C, 220°C, 230°C, 240°C, 250°C, 260°C, 270°C, 280°C, 290°C, 300°C, 310°C, 320°C, 330°C, 340°C, 350°C, 360°C, 370°C, 380°C, 390°C, or 400°C. When heated by the heater member 21, steam containing components derived from the aerosol base material and components derived from flavor components is generated from the tobacco rod portion 11 and reaches the user's oral cavity through the mouthpiece portion 14, which is composed of a cooling segment 12, a filter segment 13, etc.

[0056] From the viewpoint of promoting the inflow of air from the outside and suppressing the retention of components and air generated by heating in the cooling segment 12, it is preferable that the opening V provided in the cooling segment 12 is located closer to the mouth end than the end (indicated by the arrow X in the figure) of the region in contact with the electrically heated device 20 in the cooling segment 12, as shown in Fig. 4. In addition, the insertion opening for the non-combustion heat-not-burn tobacco 10 of the electrically heated device 20 may be tapered as shown in Fig. 5 to facilitate the insertion of the non-combustion heat-not-burn tobacco 10. In this case, the end of the region in contact with the electrically heated device 20 on the mouth end side is the position indicated by the arrow Y in the figure. Note that, for the non-combustion heat-not-burn tobacco 10 in Figs. 4 and 5, some of the reference symbols representing the components shown in Figs. 1 to 3 are omitted. EXAMPLES

The non-combustion heat-not-burn tobacco of Comparative Example 3 did not have sufficient hardness, so the delivery amount described below was not evaluated.

[0068] Table 1 summarizes the production conditions and characteristics of the non-combustion heating tobacco in each of the above-mentioned examples.

[0069] [Table 1]

[0070] <Evaluation of delivery volume> The non-combustion heat-not-burn tobacco products prepared in Examples 1 to 7 and Comparative Examples 1 to 3 were subjected to a smoking test. The delivery amount of the components generated by heat was evaluated. The smoking test was conducted using the Canadian Intense Regime The test was carried out under the following conditions, with reference to (CIR). An electric heating device that heats the periphery was used, and after inserting a non-combustion heated tobacco, the heater temperature was raised to 295°C within 21 seconds, lowered to 260°C within 5 seconds, and maintained at 260°C until the end of the evaluation (about 330 seconds). After this, the smoking test was performed using a Borgwaldt single-puff automatic smoking machine under the conditions of a flow rate of 55cc / 2 seconds and a smoking interval of 30 seconds. At this time, the opening in the cooling segment was set to be 25.5 mm from the end of the mouth end side of the region where the non-combustion heated tobacco and the electric heating device contact. The mainstream smoke generated in the smoking test was collected on a Cambridge pad, and after 12 puffing actions for Examples 1 to 6 and Comparative Example 1, and 10 puffing actions for Examples 7 and 8 and Comparative Examples 2 and 3, the Cambridge pad was removed and extracted with 10 ml of ethanol, and the amount of each component in the mainstream smoke collected at each puffing action was measured using GC-MS. Example 1 7 and Comparative Example 1 ~2The amounts of nicotine and glycerin in the mainstream smoke of the non-combustion heat-not-burn tobacco are shown in Tables 2 and 3 and Figures 6 to 9 below as indicators of the amounts of the components in the mainstream smoke obtained from the above measurements. Specifically, Figure 6 shows the results of Examples 1 and 3 and Comparative Example 1 (no capsule, no menthol, no center hole). segment Length of filter segment: length of filter segment = 12:8 single FIG. 7 shows the results of Example 7 and Comparative Example 2 (with capsule, with menthol, with center hole) and FIG. segment Length of filter segment: length of filter segment = 8:12 single FIG. 8 shows the results of Examples 2 and 4 (with capsule, without menthol, center hole) and FIG. segment Length of filter segment: length of filter segment = 12:8 single FIG. 9 shows the results of Examples 5 and 6 (no capsule, no menthol, center hole) segment (Investigation of the effect of monofilament denier under the condition of filter segment length: filter segment length = 6:14) Note that for the examples and comparative examples in which capsules were added, the flavor capsules were crushed before the above evaluation.
