Abstract
The present invention relates to a non-combustion heating type tobacco which is rod-shaped and comprises a tobacco rod portion and a mouthpiece portion, wherein the mouthpiece portion comprises a filter section having a filter medium, and the filter medium is composed of fibers having a Y-shaped cross section in the circumferential direction and having a single fiber denier of 8 to 12.
Description
Technical Field
The present invention relates to non-combustion heated tobacco and electrically heated tobacco products.
Background
In recent years, as a substitute for cigarettes (cigarettes), an electrically heated tobacco product composed of non-combustion heated tobacco used by inserting an electrically heated device has been disclosed (patent document 1). The non-combustion heating tobacco generally comprises: a tobacco rod obtained by wrapping tobacco shreds, a material for generating flavor components, and the like with a roll paper, a mouthpiece for sucking components generated from the tobacco rod by heating, and a tipping paper for wrapping them.
In general, in an electrically heated tobacco product, after non-combustion heated tobacco is inserted into an electrically heated device, a heater member is heated, whereby a tobacco rod is heated with a portion in contact with the heater member as a starting point, and the generated component is delivered to a user.
The delivery of components by heating is not limited to electrically heated tobacco products, but is also considered an important feature for cigarettes and has been widely studied.
Patent document 2 discloses a cigarette in which a volatile additive contained in a polysaccharide gel is added to a rod to increase the amount of volatile flavor to be delivered in the cigarette at the time of first smoking, so that the release of the volatile flavor does not occur even during storage, and a desired amount of volatile flavor to be delivered can be maintained at the time of smoking after storage.
Patent document 3 discloses a cigarette in which an adsorbent or a liquid absorbent is added to a filter disposed downstream of a tobacco rod, thereby reducing undesirable components generated by combustion and delivering a good flavor.

Disclosure of Invention
Problems to be solved by the invention
Patent documents 1 and 2 disclose techniques for adjusting the amount of volatile components by adding a specific material to a tobacco rod or a filter tip to achieve desired component delivery. There is little research on a technique for improving the transport of components generated by heating from the viewpoint of the structure of the material constituting the filter, as compared with a technique for improving the transport of components from the viewpoint of the material contained in such tobacco.
In addition, since the heating temperature at the time of using an electrically heated tobacco product is low as compared with a cigarette accompanied by combustion, the amount of the produced component is small, and thus, improvement in the amount of the component to be delivered is particularly desired.
Accordingly, an object of the present invention is to provide non-combustion heated tobacco and electrically heated tobacco products in which the amount of components delivered by heating is improved.

< non-Combustion heating tobacco >)
The non-combustion heating tobacco (also simply referred to as "non-combustion heating tobacco") according to one embodiment of the present invention is a rod-shaped non-combustion heating tobacco provided with a tobacco rod portion and a mouthpiece portion, wherein,
the mouthpiece part is provided with a filter section having a filter material,
the filter medium is composed of fibers having a Y-shaped cross section in the circumferential direction and having a single fiber denier of 8 to 12.
Fig. 1 shows an example of non-combustion heating tobacco according to an embodiment. Hereinafter, non-combustion heating tobacco will be described with reference to fig. 1.
The rod-shaped non-combustion heating tobacco 10 shown in fig. 1 is a rod-shaped non-combustion heating tobacco comprising a tobacco rod portion 11, a mouthpiece portion 14, and a wrapping paper 15 wrapping them, wherein the mouthpiece portion 14 includes a cooling section 12 and a filter section 13 containing a filter medium, the cooling section 12 is sandwiched adjacent to the tobacco rod portion 11 and the filter section 13 with respect to the axial direction (also referred to as "long axis direction") of the non-combustion heating tobacco 10, and holes V may be provided concentrically along the circumferential direction of the cooling section 12. The opening V is a hole for facilitating the inflow of air from the outside by the suction of the user, and the inflow of air can reduce the temperature of the component or air flowing from the stem 11.
In the non-combustion heating tobacco 10, the component generated by heating the stem 11 or the like is transported into the mouth of the user through the mouthpiece. Examples of the component generated by heating include: flavor components derived from flavors, nicotine from tobacco leaves, tar, aerosol components derived from aerosol substrates. In the present specification, an aerosol substrate refers to a substrate for generating an aerosol.
The non-combustion heated tobacco 10 preferably has a columnar shape satisfying the shape having an aspect ratio of 1 or more defined below.
Aspect ratio = h/w
w is the width of the bottom surface of the columnar body (in this specification, the width of the bottom surface on the stem portion side), and h is the height, preferably h.gtoreq.w. In the present specification, the long axis direction is defined as a direction indicated by h. Therefore, even when w.gtoreq.h, the direction indicated by h is 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, or the like, and the width w may be a diameter in the case of the bottom surface being a circle, a long diameter in the case of the bottom surface being an ellipse, or a diameter of the circumscribed circle or a long diameter of the circumscribed ellipse in the case of the polygon or the rounded polygon.
The length h of the non-combustion heating tobacco 10 in the longitudinal direction is not particularly limited, and is, for example, usually 40mm or more, preferably 45mm or more, and more preferably 50mm or more. In addition, the diameter is usually 100mm or less, preferably 90mm or less, more preferably 80mm or less.
The width w of the bottom surface of the columnar body of the non-combustion heating tobacco 10 is not particularly limited, and is, for example, usually 5mm or more, preferably 5.5mm or more. In addition, it is usually 10mm or less, preferably 9mm or less, more preferably 8mm or less.
The ratio of the length of the cooling section and the length of the filter section (cooling section: filter section) in the longitudinal direction of the non-combustion heated tobacco is not particularly limited, but is usually 0.60:1.40 to 1.40:0.60, 0.80 to 1.20:0.80 to 1.20, preferably 0.85 to 1.15:0.85 to 1.15, more preferably 0.90 to 1.10:0.90 to 1.10, still more preferably 0.95 to 1.05:0.95 to 1.05 from the viewpoint of the amount of the flavor to be delivered.
By setting the ratio of the lengths of the cooling section and the filter section to be within the above range, it is possible to achieve a cooling effect, an effect of suppressing loss by adhering generated vapor and aerosol to the inner wall of the cooling section, and an effect of achieving a balance of the air amount and flavor adjusting function of the filter and exhibiting a good flavor. In particular, when the cooling section is lengthened, the atomization of aerosol or the like is promoted, and a good flavor can be achieved, but when the cooling section is too long, adhesion of the passing substance to the inner wall occurs.
The ventilation resistance in the longitudinal direction of the non-combustion heated tobacco 10 is not particularly limited on average per 1 non-combustion heated tobacco 10, and is usually 8mmH from the viewpoint of the easiness of suction 2 O or more, preferably 10mmH 2 O or more, more preferably 12mmH 2 O or more, in addition, usually 100mmH 2 O or less, preferably 80mmH 2 O or less, more preferably 60mmH 2 O is less than or equal to.
The ventilation resistance is measured according to the ISO standard method (ISO 6565:2015) using, for example, a filter ventilation resistance measuring instrument manufactured by SelRean corporation. The ventilation resistance is that inWhen air of a predetermined air flow rate (17.5 cc/min) is flowed from one end face (end face 1) to the other end face (end face 2) without permeation of air through the side face of the non-combustion heated tobacco 10, the air pressure difference between the end faces 1 and 2 is decreased. Units are generally in mmH 2 O represents. It is known that the relationship between the ventilation resistance and the length of the non-combustion heated tobacco is proportional to the length of the non-combustion heated tobacco in a range of the length (length 5mm to 200 mm) which is generally practiced, and if the length is doubled, the ventilation resistance of the non-combustion heated tobacco is doubled.
[ smoke nozzle ]
The mouthpiece portion 14 includes a filter segment 13 having a filter medium which is formed of fibers having a Y-shaped cross section in the circumferential direction and having a single fiber denier of 8 to 12, and may be configured as follows, for example, as shown in fig. 1, without particular limitation: comprises a cooling section 12 and a filter section 13 containing the filter material, and the cooling section 12 is held adjacent to the tobacco rod 11 and the filter section 13 with respect to the axial direction of the non-combustion heated tobacco 10. The filter section 13 and the cooling section 12 will be described in detail below.
(Filter section)
The filter segment 13 includes a filter medium composed of fibers having a Y-shaped cross section in the circumferential direction and having a single fiber denier of 8 to 12 inclusive, and is not particularly limited as long as it has a function as a general filter. Typical functions of the filter may be exemplified by, for example: the amount of air mixed during aerosol inhalation, the flavor reduction, nicotine and tar reduction, etc. are adjusted, but not all of these functions are required. In addition, in electrically heated tobacco products, which have a tendency to produce less components and to have a low filling rate of tobacco filler than in tobacco products, it is one of important functions to suppress the filtration function and prevent the tobacco filler from falling off.
The shape of the filter segment 13 is not particularly limited, and a known shape may be used, and a generally cylindrical shape may be used.
The cross-sectional shape of the filter segment 13 in the circumferential direction is substantially circular, and the diameter of the circle can be changed as appropriate according to the size of the product, and is usually 4.0mm or more and 9.0mm or less, preferably 4.5mm or more and 8.5mm or less, more preferably 5.0mm or more and 8.0mm or less. When the cross section in the circumferential direction is not circular, the diameter described above may be applied to a circle having the same area as the cross section.
The length of the circumference of the cross-sectional shape of the filter segment 13 in the circumferential direction can be changed as appropriate according to the size of the product, and is usually 14.0mm or more and 27.0mm or less, preferably 15.0mm or more and 26.0mm or less, more preferably 16.0mm or more and 25.0mm or less.
The length of the filter segment 13 in the longitudinal direction may be appropriately changed depending on the size of the product, and is usually 15mm or more and 35mm or less, preferably 17.5mm or more and 32.5mm or less, more preferably 20.0mm or more and 30.0mm or less.
The shape and size of the filter medium may be appropriately adjusted so that the shape and size of the filter segment 13 are within the above-described ranges, and the length of the filter medium in the longitudinal direction may be appropriately changed in accordance with the size of the product, and is usually 3mm or more and 30mm or less, preferably 5mm or more and 20mm or less, more preferably 8mm or more and 18mm or less, and still more preferably 10mm or more and 15mm or less, from the viewpoint of obtaining a desired hardness.
The ventilation resistance in the longitudinal direction of the filter segment 13 is not particularly limited, but is usually 1.0mmH from the viewpoint of the easiness of suction 2 O/mm or more and 4.0mmH 2 O/mm or less. In particular, when the filter medium has a flavor capsule described later, it is preferably 1.5mmH from the viewpoint of the easiness of suction 2 O/mm or more and 4.0mmH 2 In the case where the filter medium further contains a flavoring agent described later, the filter medium preferably contains crystalline substances such as menthol as a flavoring agent, more preferably 2.5mmH 2 O/mm or more and 3.6mmH 2 O/mm or less, on the other hand, in the case of containing no flavoring agent, more preferably 1.9mmH 2 O/mm or more and 3.0mmH 2 O/mm or less. The filter medium does not have a flavor gel described laterIn the case of the capsule, from the viewpoint of the easiness of aspiration, 1.3mmH is preferable regardless of whether the perfume is contained 2 O/mm or more and 2.4mmH 2 O/mm or less. The conditions of the ventilation resistance may be applied as conditions of the ventilation resistance in the ventilation direction of the filter medium.
The ventilation resistance is measured according to the ISO standard method (ISO 6565) using, for example, a filter ventilation resistance measuring device manufactured by selean corporation. The ventilation resistance of the filter segment 13 is an air pressure difference between the 1 st end face and the 2 nd end face when air of a predetermined air flow rate (17.5 cc/min) is flowed from one end face (1 st end face) to the other end face (2 nd end face) in a state where air permeation of the side face of the filter segment 13 is not performed. Units are generally in mmH 2 O represents. The relationship between the ventilation resistance of the filter section 13 and the length of the filter section 13 is known to be proportional in the length range (length 5mm to 200 mm) in which it is generally practiced, and if the length is doubled, the ventilation resistance of the filter section 13 is doubled.
The filter segment 13 may be a single filter including a single filter segment, a multi-segment filter including a plurality of filter segments, such as a dual filter or a triple filter.
The filter segment 13 can be produced by a known method, for example, in the case of using synthetic fibers such as cellulose acetate tow as a material of a filter material, it can be produced by a method of spinning and crimping a polymer solution containing a polymer and a solvent. As this method, for example, a method described in international publication No. 2013/067511 can be used.
In the manufacture of the filter segment 13, adjustment of the ventilation resistance, addition of additives (known adsorbents, flavors (e.g., menthol), granular activated carbon, flavor-retaining materials, etc.) to the filter material may be appropriately designed.
The filter material constituting the filter segment 13 is not particularly limited as long as it is composed of fibers having a Y-shaped cross section in the circumferential direction and having a single fiber denier of 8 to 12, and for example, a filter material in which a tow such as a cellulose acetate tow having a Y-shaped cross section is processed into a cylindrical shape may be used.
The shape of the circumferential cross section of the fibers constituting the tow is a Y-shape. When a tow having a fiber shape of Y is used, a filter segment having an excellent component transfer amount can be easily obtained because of the complicated fiber shape, compared with a tow having a general fiber shape such as a round shape, and in particular, a filter segment having a high component transfer amount and a desired hardness can be produced with a small amount, that is, with a low cost.
From the viewpoint of increasing the transport amount of the component generated by heating, the single fiber denier (g/9000 m) of the fiber is not particularly limited as long as it is 8 to 12, and may be 9 to 11. When the single fiber denier of the fibers is smaller than the above range, the structure of the fibers constituting the filter medium becomes too dense, and the amount of the components to be transported decreases, and when it is larger than the above range, the structure of the fibers constituting the filter medium becomes too sparse, and thus sufficient hardness cannot be obtained. The total fiber denier (g/9000 m) of the fibers is not particularly limited, and may be 12000 to 35000, preferably 15000 to 30000 from the viewpoint of increasing the transport amount of the component generated by heating. These single fiber denier and total fiber denier are particularly preferred when the circumference of the mouthpiece is 22 mm. In the case of a fiber-filled filter, in order to improve the filter hardness, 5 to 10 wt% of glyceryl triacetate may be added to the total fiber weight.
The method for producing a fiber having a Y-shaped cross section in the circumferential direction is not particularly limited, and for example, in the case of an acetate fiber, a cellulose acetate sheet (cellulose acetate) may be produced by acetylation of a pulp raw material, and then the cellulose acetate sheet is dissolved in acetone (spinning dope) by a dissolver and spun to produce a fibrous bundle, and in this spinning step, the cross section in the circumferential direction may be changed to a Y-shape by changing the shape of a nozzle orifice, and the thickness (filament denier) of the fiber may be changed by changing the nozzle aperture. Then, the total denier can be determined based on the necessary air resistance, thereby determining the number of bundled filaments (total denier ++filament denier), spinning is performed using the necessary number of spinning chambers, the spun bundled acetate fibers are formed into a uniform wave pattern (crimped) by a crimping machine, and the filament bundles fed in a band shape are patterned and laminated and packaged by a packaging machine.
The density of the filter medium (particularly, the density in a state where the flavor capsule is removed in the case of containing the flavor capsule described later) is not particularly limited, but is usually 0.09g/cm from the viewpoint of obtaining a desired hardness 3 Above and 0.25g/cm 3 The following is preferable to be 0.09g/cm 3 Above and 0.20g/cm 3 Hereinafter, more preferably 0.09g/cm 3 Above and 0.14g/cm 3 The following is more preferably 0.11g/cm 3 Above and 0.14g/cm 3 The following is given.
The compression change rate P of the filter material represented by the following formula (1) is one of indexes indicating hardness, and is not particularly limited, but is usually 85% to 98%, preferably 88% to 95%, more preferably 90% to 93% from the viewpoint of obtaining a desired hardness. The method for measuring the compression change rate P is not particularly limited, and may be measured using, for example, sodim-H Hardness module manufactured by Sodim SAS, and the value thereof may be adjusted by changing the density and material of the filter medium.
P＝(D1×100)/D2 (1)
P (%): compression change rate
D1 (mm): the diameter D2 (mm) of the filter medium in the compression direction after compressing the filter medium under a compression load of 3N/mm per unit length in the long axis direction for 10 seconds was such that the filter medium was deformed in the direction perpendicular to the ventilation direction (in the case of the cylindrical shape, the circumferential direction): average diameter of filter media before compression
In addition, since the compression change rate is one of indexes indicating the hardness of the filter material, the compression change rate is also indicated as "hardness" in the present specification.
The filter medium may contain a component such as a flavor material different from the flavor capsule described later, and examples of the flavor include: menthol, spearmint, peppermint, fenugreek, clove, or medium chain fatty acid triglycerides (MCT), and the like, preferably menthol. These components may be used alone in 1 kind, or may be used in combination of 2 or more kinds in any kind and ratio.
The content of the flavor (particularly menthol) in the filter medium (excluding the flavor in the flavor capsule described later) is not particularly limited, but is usually 0.5% by weight or more and 15% by weight or less, preferably 3% by weight or more and 10% by weight or less, more preferably 10% by weight or more and 5% by weight or less.
The filter medium may be internally provided with a breakable additive releasing container (for example, a flavor capsule) including a breakable outer shell such as gelatin. The manner of the flavor capsule (also referred to as "additive releasing container" in this technical field) is not particularly limited, and a known manner may be employed, for example, a breakable additive releasing container including a breakable outer shell such as gelatin may be employed. In this case, the flavour capsule releases a liquid or substance (typically a flavour) contained within the flavour capsule when it is broken before, during or after use by a user of the tobacco product, which liquid or substance is then transferred into the smoke of the tobacco during use of the tobacco product and to the surrounding environment after use.
The form of the flavor capsule is not particularly limited, and for example, the flavor capsule may be a breakable flavor capsule, and the shape thereof is preferably a sphere. The additive contained in the flavor capsule may be any of the above additives, and particularly preferably contains a flavoring agent and activated carbon. In addition, as an additive, 1 or more materials that contribute to the filtration of smoke may be added. The form of the additive is not particularly limited, and is usually liquid or solid. It is noted that the use of capsules containing additives is well known in the art. Breakable perfume capsules and methods of making the same are well known in the art.
As flavoring agents, menthol, spearmint, peppermint, fenugreek, clove, or medium chain fatty acid triglycerides (MCT) and the like can be used, for example. The flavoring agent is menthol, or menthol, etc. or a combination thereof may be used.
When the flavor capsule is used, if the filament denier of the fibers constituting the filter medium exceeds the upper limit of the above range, the diffusion of the component released from the flavor capsule into the filter tends to be insufficient, and if the concentration of the component is less than the lower limit, the diffusion into the filter tends to be excessive, so that the component transport amount tends to be excessively suppressed.
From the viewpoint of improving strength and structural rigidity, the filter segment 13 may include a roll paper (plug wrap) for wrapping the filter material. The manner of winding the paper is not particularly limited, and may include one or more lines of joints including an adhesive. The adhesive may comprise a hot melt adhesive, and in addition, the hot melt adhesive may comprise polyvinyl alcohol. In the case where the filter segment includes two or more segments, the roll paper is preferably wound by combining the two or more segments.

The basis weight of the roll paper is not particularly limited, and is usually 20gsm to 100gsm, preferably 22gsm to 95gsm, more preferably 23gsm to 90 gsm.
The wound paper may or may not be coated, and it is preferable to coat the wound paper with a desired material from the viewpoint of imparting functions other than strength and structural rigidity.
The filter section 13 may further comprise a central bore section having one or more hollows. The center hole section is generally disposed closer to the cooling section than the filter medium, and is preferably disposed adjacent to the cooling section.
The central hole section is composed of a filling layer with one or more hollow parts and an inner rod coating the filling layerPackaging (inner winding paper). For example, the central bore section is formed of a filling layer having a hollow portion and an inner rod wrapper that encases the filling layer. The central aperture section has the function of increasing the strength of the mouthpiece section. For example, the filler layer may be formed by filling cellulose acetate fibers with a high density, and may be cured to have an inner diameter by adding a plasticizer containing triacetin in an amount of 6 to 20 mass% based on the mass of cellulose acetateAbove and/or (II)>The following rods. Since the filling density of the fibers of the filling layer is high, air and aerosol flow only through the hollow portion during suction, and substantially do not flow into the filling layer. The filling layer inside the central hole section is a fiber filling layer, and the touch feeling from the outside is less likely to cause discomfort to the user in use. The central hole section may be formed by thermoforming without the inner rod package.
The central bore section and filter plug may be joined together by, for example, an outer rod wrapper (outer wrap). The outer rod package may be, for example, cylindrical paper. In addition, the tobacco stem portion 11, cooling section 12, connected central bore section and filter plug material may be connected together by, for example, a tipping paper. These connections may be made by, for example, applying a glue such as vinyl acetate glue to the inner side of the tipping paper, and inserting and winding the tobacco rod portion 11, the cooling section 12, and the connected center hole section and filter medium. It should be noted that they may be connected together by dividing a plurality of interleaving papers into a plurality of times.

When an aerosol base material is used in the stem portion, the vapor containing the aerosol base material and the tobacco flavor component, which is generated by heating the stem, is liquefied by contact with air from the outside, and thus the aerosol generation can be promoted.
In the case where the holes V existing in concentric circles are treated as 1 hole group, the number of hole groups may be 1, or may be 2 or more. When there are 2 or more groups of openings, it is preferable that the groups of openings are not provided in a region of less than 4mm in the direction of the cooling section side from the boundary between the cooling section and the filter section, from the viewpoint of increasing the transport amount of the component generated by heating.

The production conditions and properties of the non-combustion heated tobacco in each of the above examples are summarized in table 1.
< evaluation of delivery amount >
The non-combustion heated tobacco produced in examples 1 to 7 and comparative examples 1 to 3 was subjected to a smoking test, and the amount of the component transported by heating was evaluated.
Smoking tests were performed under the following conditions with reference to Canadian Intense Smoking (CIR).
After inserting non-combustion heating tobacco using an electric heating apparatus for peripheral heating, the heater temperature was raised to 295℃within 21 seconds, lowered to 260℃within 5 seconds, and maintained at 260℃until the end of the evaluation (about 330 seconds). Then, the smoking test was carried out by using a single automatic smoking machine manufactured by Borgwaldt, inc. at a flow rate of 55cc/2 seconds and a smoking interval of 30 seconds. At this time, the opening formed in the cooling section was 25.5mm from the end on the suction port end side of the region where the non-combustion heating tobacco contacted the electric heating apparatus. The mainstream smoke generated in the smoking test was trapped in the cambridge pad, 12 times of smoking operations were performed for examples 1 to 6 and comparative example 1, 10 times of smoking operations were performed for examples 7 and 8 and comparative examples 2 and 3, and then the cambridge pad was taken out, extracted with 10ml of ethanol, and the amounts of the components in the mainstream smoke collected by each smoking operation were measured by GC-MS.
In the non-combustion heating tobacco of examples 1 to 9 and comparative example 1, the amounts of the respective components of nicotine and glycerin are shown in tables 2 and 3 below and fig. 6 to 9 as an index of the amounts of the components in the mainstream smoke obtained by the above measurement. Specifically, the results of examples 1 and 3 and comparative example 1 (no capsule, no menthol, length of center hole: length of filter segment=consideration of fiber denier under conditions of 12:8), the results of example 7 and comparative example 2 (no capsule, menthol, length of center hole: length of filter segment=consideration of fiber denier under conditions of 8:12), the results of examples 2 and 4 (no capsule, menthol, length of center hole: consideration of fiber denier under conditions of 12:8), and the results of examples 5 and 6 (no capsule, menthol, length of center hole: consideration of single fiber denier under conditions of 6:14) are shown in fig. 6. In the examples and comparative examples in which the capsules were added, the above evaluation was performed after the flavor capsules were crushed.
/>
As is clear from tables 1 and 2 and fig. 6 to 9, the non-combustion heated tobacco having a single fiber denier of 8 or more and 12 or less is superior from the viewpoint of the transport amount in the case of nicotine and glycerin, which are both indexes of the component amount of the mainstream smoke, compared to the non-combustion heated tobacco having a short fiber denier outside the range, regardless of the presence or absence of the flavor capsule and the menthol added to the filter medium.
