Description

Filter section, non-combustion heating smoking article and non-combustion heating smoking system

Technical Field

The invention relates to a filter section, a non-combustion heating smoking article and a non-combustion heating smoking system.

Background

A general combustion smoking article (tobacco) for smoking by combustion includes a tobacco-containing segment formed by winding a tobacco filler into a cylindrical shape with a paper-made packing material, and a mouthpiece segment formed by winding a fiber formed of cellulose acetate or the like or a paper roll provided with wrinkles into a cylindrical shape with a paper-made packing material, in which a flavor, a humectant, an appropriate amount of moisture, and the like are added to dry tobacco leaves cut to a width of about 1 mm. The tobacco-containing section and the cigarette holder section are connected together through lining paper. The user ignites the end of the tobacco-containing segment with a lighter or the like, and draws the tobacco from the end of the mouthpiece segment to smoke. The front end of the tobacco-containing segment is burned at a temperature exceeding 800 ℃.

As an alternative to such a general combustion smoking article, a non-combustion heating smoking article and a non-combustion heating smoking system have been developed, in which combustion is replaced by heating (for example, patent documents 1 to 6). The heating temperature is lower than the combustion temperature in a burning smoking article, for example at 400 ℃ or lower. In a non-combustion heated smoking article, the tobacco segment-containing tobacco filler comprises an aerosol-generating substrate such as glycerin, Propylene Glycol (PG), triethyl citrate (TEC), triacetin, and the like. The aerosol-generating substrate is vaporised by heating and moved by suction to a cooling segment within the mouthpiece segment, after cooling more reliably generating an aerosol. When the aerosol is sucked from the filter segment provided at the end portion on the mouthpiece side in the mouthpiece segment, the aerosol is also sucked together, and therefore, the user's satisfaction can be ensured.

The non-combustion heating smoking system generally includes: a columnar non-combustion heating smoking article having a shape similar to that of a general combustion smoking article, and a heating device including a battery, a controller, a heater, and the like. Examples of the heater include a heater using a resistor and a heater using IH. Examples of a heating method of the heater using the resistance include: a method of heating from the outside of a non-combustion heated smoking article with a heater; a method of inserting a needle-like or blade-like heater into a tobacco-containing segment containing tobacco filler from the tip of a non-combustion heating smoking article to heat the smoking article, and the like.

Problems to be solved by the invention

As described above, the aerosol-generating substrate (hereinafter also referred to as an aerosol-vaporized component) vaporized by heating is cooled mainly in the cooling stage, and condensation from vapor to particles occurs to become an aerosol. Here, the aerosol vaporizing composition is required to be sufficiently cooled so that a user can draw from a filter segment provided at the end of the mouthpiece side. As a cooling stage for a non-combustion heating smoking article, for example, patent document 4 discloses the following configuration: the outer periphery of the cylindrical portion of the cavity is provided with perforations, and external air is introduced from the perforations during suction, and the aerosol vaporization component is cooled by contacting the external air.

However, when the aerosol-vaporized component is cooled only by the outside air introduced from the perforations provided in the cooling stage, a large amount of outside air needs to be introduced to sufficiently perform the cooling, and thus the smell of the aroma is impaired. Accordingly, it is desirable to develop a method that enables the aerosol vaporization component to be sufficiently cooled without impairing the flavor of the aerosol.

The present invention aims to provide a filter segment capable of sufficiently cooling aerosol gasified components without impairing the flavor of the aerosol, a non-combustion heating smoking article and a non-combustion heating smoking system provided with the filter segment.

Means for solving the problems

The filter section is a filter section for non-combustion heating smoking articles, wherein the ventilation resistance of each section is 15-60 mmH₂O/seg。

The non-combustion heating smoking article of the present invention comprises: a tobacco-containing section, a cylindrical cooling section having perforations on the outer periphery, and the filter section.

The non-combustion heating smoking system of the present invention comprises: the non-combustion heated smoking article, and a heating device for heating the tobacco-containing segment.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, it is possible to provide a filter segment capable of sufficiently cooling an aerosol vaporization component without impairing the flavor of a cigarette, a non-combustion heating smoking article and a non-combustion heating smoking system provided with the filter segment.

Detailed Description

[ Filter segment ]

The filter segments of the present invention are filter segments for non-combustion heated smoking articles. Here, the air flow resistance of each filter segment is 15-60 mmH₂O/seg。

In the present invention, the ventilation resistance of each stage is set to 15 to 60mmH₂In the range of O/seg, so that the aerosol vaporization component can be sufficiently cooled without impairing the flavor of the aerosol. Specifically, the ventilation resistance per stage was set to 15mmH₂Above the O/seg, the aerosol and water vapor are sufficiently captured in the filter segment, and thus heat is also captured together. Further, the trapped aerosol and water vapor exhibit a cooling effect. Thus, a cooling effect can thereby be obtained in the filter segment. Further, the ventilation resistance per stage was set to 60mmH₂The amount of O/seg or less can suppress unnecessary trapping of aerosol, and the tobacco component and flavor component contained in the aerosol can be sufficiently supplied to the user, so that the flavor is not impaired. Further, even when the filter is cooled by the outside air introduced from the perforations provided in the cooling section, the cooling effect can be obtained in the filter section, and therefore, the amount of the outside air introduced from the perforations can be reduced, and a sufficient flavor can be obtained. The present invention will be described in detail below.

Fig. 1 shows an example of the structure of the filter segment of the present invention. The filter segment 1 shown in figure 1 is comprised of a first filler layer 2 and a first inner rod forming paper 3 which encases the first filler layer 2. In the filter segment 1, the first filler layer 2 is present up to the end, and therefore, the end has the same appearance as a normal combustion smoking article. The filler of the first filling layer 2 may be, for example, cellulose acetate tow to which a plasticizer (triacetin) is added, paper made of pulp as a main raw material, or the like. One of these fillers may be used, or two or more of them may be used in combination.

In the invention, the ventilation resistance of each section of the filter section is 15-60 mmH₂O/seg, preferably 20 to 40mmH₂O/seg, more preferably 25 to 30mmH₂O/seg. For example, in the case where the length of the filter segment in the axial direction (horizontal direction in FIG. 1) is 7mm, the ventilation resistance per segment is 15 to 60mmH₂O/7 mm. The ventilation resistance can be changed as appropriate by the amount and material of the filler filled in the filter segment. For example, in the case where the filler is cellulose acetate fibers, if the amount of cellulose acetate fibers filled in the filter segment is increased, the ventilation resistance can be increased. When the filler is cellulose acetate fiber, the cellulose acetate fiber may have a packing density of 0.13 to 0.18g/cm³. The air flow resistance is a value measured by an air flow resistance measuring instrument (trade name: SoDIMAX, manufactured by SODIM).

The circumference of the filter segment is not particularly limited, but is preferably 16 to 25mm, more preferably 20 to 24mm, and still more preferably 21 to 23 mm. The length of the filter segment in the axial direction (horizontal direction in fig. 1) can be selected from 4 to 10mm, and the ventilation resistance can be 15 to 60mmH₂The O/seg mode is selected. The axial length of the filter section is preferably 5-9 mm, and more preferably 6-8 mm. The shape of the cross section of the filter segment is not particularly limited, and may be, for example, circular, elliptical, polygonal, or the like. Alternatively, flavor-containing destructive capsules, flavor beads, or flavors may be added directly to the filter segment.

[ non-burning heating smoking article ]

The non-combustion heating smoking article of the present invention comprises: a tobacco-containing segment, a cylindrical cooling segment having perforations on the outer periphery, and a filter segment of the present invention. The above-described non-combustion heating smoking article is provided with the filter segment of the present invention, and therefore, the aerosol vaporization component can be sufficiently cooled without impairing the flavor. The non-combustion heated smoking article of the present invention may have other sections in addition to the tobacco containing section, cooling section, and filter section.

Fig. 2 shows an example of a non-combustion heating smoking article of the present invention. The non-combustion heating smoking article 30 shown in fig. 2 includes: a tobacco containing segment 10, and a mouthpiece segment 11. The mouthpiece section 11 includes: a cooling section 12, a central bore section 13, and a filter section 1 of the present invention disposed at the end on the side of the mouthpiece. During smoking, the tobacco-containing segment 10 is heated and drawn from the end of the filter segment 1. It should be noted that the positions of the cooling section 12 and the central hole section 13 may be exchanged, and the positions of the central hole section 13 and the filter section 1 may also be exchanged. In addition, the mouthpiece section 11 may not have a central bore section 13.

The tobacco-containing segment 10 has: a tobacco filler 14 containing tobacco and an aerosol-generating substrate, and a cylindrical wrapping material 15 covering the tobacco filler 14. The tobacco filler 14 may further contain a volatile flavor component, water. The size of the tobacco used as the filler and the method for producing the same are not particularly limited. For example, cut tobacco in which dried tobacco leaves are cut into pieces having a width of 0.8 to 1.2mm can be used. When the shredded tobacco is cut into the above width, the length of the shredded tobacco is about 5-20 mm. Further, the dried tobacco leaves may be pulverized into a uniform material having an average particle diameter of about 20 to 200 μm, and then processed into pieces, and the pieces may be cut into tobacco shreds having a width of 0.8 to 1.2 mm. When the shredded tobacco is cut into the above width, the length of the shredded tobacco is about 5-20 mm. Further, the tobacco pieces after the sheet processing may be collectively processed and used as filler without being cut. Further, a plurality of pieces molded into a cylindrical shape may be arranged in a concentric circle shape. Similarly, when the dried tobacco leaves are cut and used, and when the tobacco leaves are used in the form of a sheet after being pulverized and homogenized, various types of tobacco can be used as the tobacco contained in the tobacco filler. Yellow seed, burley seed, oriental tobacco seed, indigenous variety, and other tobacco (Nicotiana tabacum) line varieties, and yellow flower tobacco (Nicotiana rustica) line varieties can be appropriately mixed and used to achieve the target taste. The details of the above tobacco varieties are disclosed in "the tobacco classics, the tobacco general research center, 2009.3.31".

There are a number of conventional methods for processing tobacco into a homogenized sheet by pulverizing the tobacco. The first is a sheet made by a papermaking process, the second is a cast sheet made by mixing and homogenizing a suitable solvent such as water, casting the mixture into a thin homogenized product on a metal plate or a metal plate belt, and drying the cast sheet, and the third is a rolled sheet made by mixing and homogenizing a suitable solvent such as water, and then extruding the mixture into a sheet shape. Details of the types of the above-mentioned homogenized sheets are disclosed in "the tobacco classics, the center for tobacco general research, 2009.3.31".

The filling density of the tobacco filler 14 is not particularly limited, and is usually 250mg/cm from the viewpoint of ensuring the performance of the non-combustion heating smoking article 30 and imparting a good taste and flavor³Above, preferably 320mg/cm³Above, in addition, usually 520mg/cm³Hereinafter, it is preferably 420mg/cm³The following. Specifically, in the case of a tobacco-containing segment 10 having a circumference of 22mm and a length of 20mm, the content of the tobacco filler 14 in the tobacco-containing segment 10 may be, for example, 200 to 450mg, preferably 280 to 400mg, per tobacco-containing segment 10.

The aerosol-generating substrate is a material that can generate an aerosol by heating, and is not particularly limited, and examples thereof include: glycerin, Propylene Glycol (PG), triethyl citrate (TEC), triacetin, 1, 3-butanediol, and the like.

In addition, these volatile perfume ingredients may be used singly or two or more kinds may be used in combination.

The content of the aerosol-generating substrate in the tobacco filler 14 is not particularly limited, and is usually 5 to 50 mass%, preferably 10 to 20 mass%, from the viewpoint of sufficiently generating aerosol and imparting good taste. When the tobacco filler 14 contains a volatile flavor component, the content of the volatile flavor component in the tobacco filler is not particularly limited, and is usually 10000ppm or more, preferably 20000ppm or more, more preferably 25000ppm or more, and usually 50000ppm or less, preferably 40000ppm or less, more preferably 33000ppm or less, relative to the amount of the tobacco filler, from the viewpoint of imparting a good taste.

The method of filling the tobacco filler 14 into the wrapping material 15 is not particularly limited, and for example, the tobacco filler 14 may be wrapped with the wrapping material 15, or the tobacco filler 14 may be filled into the cylindrical wrapping material 15. When the tobacco has a rectangular shape and a longitudinal direction, the tobacco may be filled so that the longitudinal direction of the tobacco is in an unspecified direction in the wrapping material 15, or may be filled so that the tobacco is aligned in the axial direction of the tobacco-containing segment 10 or in a direction perpendicular to the axial direction. By heating the tobacco-containing segment 10, the tobacco components, aerosol-generating substrate and water contained in the tobacco filler 14 are vaporized and moved to the mouthpiece segment 11 by suction.

The cooling stage 12 is constituted by a cylindrical member 16. The cylindrical member 16 may be, for example, a paper tube obtained by processing thick paper into a cylindrical shape. The cylindrical member 16 and a mouthpiece paper 21 described later are provided with a through hole 17 penetrating both. By the presence of the perforations 17, external air is introduced into the cooling section 12 during suction. As a result, the aerosol-vaporized component generated by heating the tobacco-containing segment 10 comes into contact with the outside air, and the temperature thereof is lowered, so that the aerosol is liquefied and formed. The diameter (diameter length) of the perforation 17 is not particularly limited, and may be, for example, 0.5 to 1.5 mm. The number of the perforations 17 is not particularly limited, and may be 1 or 2 or more. For example, the perforations 17 may be provided in plural on the outer periphery of the cooling section 12. The amount of the external gas introduced from the perforation 17 is preferably 85 vol% or less, and more preferably 80 vol% or less, based on the volume of the entire gas sucked by the user. By setting the ratio of the amount of external gas to 85% by volume or less, the reduction in the fragrance smell due to dilution with external gas can be sufficiently suppressed. The lower limit of the range of the proportion of the amount of the external gas is preferably 55 vol% or more, and more preferably 60 vol% or more, from the viewpoint of cooling performance.

The central hole section is composed of a filling layer with 1 or more hollow parts and inner filter rod forming paper covering the filling layer. For example, the central hole section 13 is constituted by a second filling layer 18 having a hollow portion and a second inner filter rod-forming paper 19 covering the second filling layer 18. The central bore section 13 has the function of increasing the strength of the mouthpiece section 11. The second filling layer 18 is filled with, for example, cellulose acetate fiber at a high density, and 6 to 20 mass% of a plasticizer containing triacetin may be added to the cellulose acetate fiber to be cured to have an inner diameterThe rod of (1). Second filling layerThe fibers of 18 have a high packing density, and therefore, air or aerosol flows only in the hollow portion during suction, and hardly flows in the second packed layer 18. The second filler layer 18 inside the central hole section 13 is a fiber filler layer, and therefore, the feeling from the outside in use is less likely to cause discomfort to the user. It should be noted that the central bore section 13 may be provided without the second inner plug wrap 19 and retain its shape by thermoforming.

The central bore section 13 is joined to the filter segment 1 by an outer plug wrap 20. The outer plug wrap 20 may be, for example, a cylindrical paper. In addition, the tobacco containing segment 10, the cooling segment 12, and the joined central bore segment 13 and filter segment 1 are joined together by a tipping paper 21. These can be connected by, for example, applying a paste such as a vinyl acetate paste to the inner surface of the mouthpiece liner paper 21, and putting and winding the 3 segments. It should be noted that the segments may be divided into multiple connections by multiple slip sheets.

The length of the non-combustion heating smoking article of the present invention in the axial direction, i.e., in the horizontal direction in fig. 2 is not particularly limited, but is preferably 40mm to 90mm, more preferably 50mm to 75mm, and still more preferably 50mm to 60 mm. The circumference of the non-combustion heating type smoking article is preferably 16mm to 25mm, more preferably 20mm to 24mm, and still more preferably 21mm to 23 mm. Examples thereof include: the tobacco-containing segment 10 has a length of 20mm, the cooling segment 12 has a length of 20mm, the central hole segment 13 has a length of 8mm, and the filter segment 1 has a length of 7 mm. It should be noted that the length of the filter segment 1 may be selected within the range of 4 to 10 mm. In addition, the ventilation resistance of the filter segment 1 is 15-60 mmH per segment₂And selecting the O/seg mode. These segment lengths may be appropriately changed according to manufacturing suitability, required quality, and the like. Further, even if only the filter segment is disposed downstream of the cooling segment without using the center hole segment, the filter segment can function as a non-combustion heating smoking article.

[ non-combustion heating smoking System ]

The non-combustion heating smoking system of the present invention comprises: the non-combustion heated smoking article of the present invention, and a heating device for heating a tobacco-containing segment. The above-described non-combustion heating smoking system is provided with the non-combustion heating smoking article of the present invention, and can sufficiently cool the aerosol vaporization component without impairing the flavor of the aerosol. The non-combustion heating smoking system of the present invention is not particularly limited as long as it includes the non-combustion heating smoking article of the present invention and the heating device, and may have other configurations.

Fig. 3 shows an example of a non-combustion heating and smoking system according to the present invention. The non-combustion heating smoking system shown in fig. 3 includes: the non-combustion heating smoking article 30 of the present invention and the heating device 31 for heating the tobacco-containing segment of the non-combustion heating smoking article 30 from the outside. Fig. 3(a) shows a state before the non-combustion heated smoking article 30 is inserted into the heating device 31, and fig. 3(b) shows a state in which the non-combustion heated smoking article 30 is inserted into the heating device 31 and heated. The heating device 31 shown in fig. 3 includes: a body 32, a heater 33, a metal pipe 34, a battery unit 35, and a control unit 36. The main body 32 has a cylindrical recess 37, and the heater 33 and the metal pipe 34 are disposed on the inner side surface of the recess 37 at positions corresponding to the tobacco-containing segment of the non-combustion heating smoking article 30 inserted into the recess 37. The heater 33 may be a heater using a resistance, and the heater 33 may be heated by supplying power from the battery unit 35 in response to an instruction from the control unit 36 that controls the temperature. The heat emitted from the heater 33 is transferred to the tobacco-containing segment of the non-combustion heated smoking article 30 through the metal tube 34 of high thermal conductivity. In fig. 3(b), although a gap is schematically illustrated, between the outer periphery of the non-combustion heated smoking article 30 and the inner periphery of the metal pipe 34, it is more desirable that no gap is provided between the outer periphery of the non-combustion heated smoking article 30 and the inner periphery of the metal pipe 34 for the purpose of efficiently conducting heat. The heating device 31 may heat the tobacco-containing segment of the non-combustion heating smoking article 30 from the outside, or may heat the tobacco-containing segment from the inside.

The heating temperature by the heating device is not particularly limited, but is preferably 400 ℃ or lower, more preferably 150 ℃ or higher and 400 ℃ or lower, and further preferably 200 ℃ or higher and 350 ℃ or lower. The heating temperature indicates the temperature of the heater of the heating apparatus.

Examples

The present invention will be described more specifically with reference to the following examples, but the present invention is not limited to these examples.

(evaluation of Cooling Performance)

The filter section of the non-combustible heated smoking article, which closes the perforations provided in the cooling section, is connected to the smoking machine via a tube. In addition, a thermocouple is disposed directly behind the filter segment. Heating the tobacco containing segment of the non-combustible heated smoking article by a heater and smoking with the smoking machine. The heating by the heater is set as follows: the temperature was maintained at 230 ℃ for 50 seconds, at 200 ℃ for 130 seconds and then at 170 ℃. The pumping is performed as follows: after 40 seconds from the start of heating, each aspiration was set to 55ml/2 seconds (one aspiration interval was 30 seconds, i.e., 2 seconds of aspiration and 28 seconds of standby), and five aspirations were counted. In the first suction, the maximum temperature detected was measured by the thermocouple, and the cooling performance was evaluated. The results are shown in Table 1. It should be noted that the aerosol temperature is highest on the first puff and therefore there is no problem in actual use if the first puff is at a temperature that is perceived as suitable for smoking. The HCI method is a method shown by the Ministry of health in Canada and is described in Haelth Canada-Tobacco Reporting Regulation SOR/2000-273. The evaluation test was conducted by closing the perforations because the cooling capacity of the filter segment alone was evaluated without using air introduced from the perforations, and because the HCI method was one of the conditions for closing the perforations and performing suction.

(sensory evaluation)

The non-combustion heated smoking article having the filter section after closing the perforations provided in the cooling section was smoked by the fully trained panel 4 at the same smoking intervals as in the above-described cooling performance evaluation, and subjected to sensory evaluation (evaluation of flavor and sensory temperature). Sensory evaluation was performed according to the following criteria.

A: is suitable for smoking in both aspects of flavor and sensory temperature.

B: is suitable for smoking in terms of sensory temperature, but has a slightly weaker flavor.

C: it is suitable for smoking in terms of its smoky flavour, but its sensory temperature is somewhat unsuitable.

(example 1)

The following tobacco-containing, cooling, center hole, and filter segments were prepared.

< containing tobacco segment >

The tobacco sheet produced in the paper making process was cut into a width of 0.8mm, and 16 mass% of glycerin as an aerosol-generating substrate was added to obtain a tobacco filler. The length in the longitudinal direction when the sheet is cut to a width of 0.8mm is about 5mm to 20 mm. In addition, the moisture content of the tobacco filler was about 12 mass%. The weight per unit area of the wood pulp as the main component is 35g/m²A 50 μm thick wrapper is wrapped around the tobacco filler to produce a tobacco containing segment. As a device for winding, a general cigarette manufacturing machine is used. The tobacco-containing segment is cylindrical, with a circumference of 22mm and an axial length of 20 mm. The tobacco filler wrapped with the wrapping material is filled in the rod in a random orientation. The mass of tobacco filler in the tobacco-containing segment was 280 mg/seg.

< Cooling section >

Using a paper tube manufacturing apparatus manufactured by Hauni corporation, and using a weight per unit area of 100g/m²And 125 μm thick paper, and a cooling section as a paper tube was manufactured. The cooling section is cylindrical with a circumference of about 21.75mm and an axial length of 20 mm. In addition, since the paper tube manufacturing apparatus was an apparatus for pasting 2 thick papers and manufacturing a paper tube, the thickness of the obtained cooling stage was about 250 μm.

A hollow center hole segment was produced by a center hole segment production apparatus manufactured by Hauni corporation using a cellulose acetate fiber bundle as a filler and triacetin for bonding cellulose acetate fibers to each other to secure segment hardness as a plasticizer. The cellulose acetate fiber bundle had a single-fiber fineness of 8.0 denier, a total fineness of 40000 denier, and a fiber cross-sectional shape of Y cross-section. To cellulose acetate fibersTriacetin was sprayed to the cellulose acetate tow in an amount of 15 mass% of the mass of the tow. The central bore section is cylindrical with a circumference of about 21.5mm and an axial length of 8 mm. In addition, an inner diameter is formed at the center of the cylinderThe hollow portion of (2). Instead of using a wrapping material for winding the cellulose acetate tow, a central hole section was made as a so-called "unwinding rod". The packing density of the cellulose acetate fiber bundle packed in a hollow shape was 0.280g/cm³。

< Filter tip segment >

A solid filter segment was manufactured using a filter manufacturing apparatus manufactured by Hauni corporation, using cellulose acetate fiber bundles as a filler and triacetin for bonding cellulose acetate fibers to each other to secure segment hardness as a plasticizer. Using a filter making apparatus, using a weight per unit area of 27g/m²The inner filter rod-forming paper of (a) was wound with the cellulose acetate fiber bundle sprayed with the triacetin. The cellulose acetate fiber bundle had a single-fiber fineness of 5 deniers, a total fineness of 35000 deniers, and a fiber cross-sectional shape of a Y cross-section. Triacetin was sprayed to the cellulose acetate fiber bundle in an amount of 6 mass% with respect to the mass of the cellulose acetate fiber bundle. The filter segments were cylindrical with a circumference of about 21.5mm and an axial length of 7 mm. The cellulose acetate fiber bundle had a packing density of 0.135g/cm³。

And connecting the central hole section and the filter section by using outer filter stick forming paper. The tobacco-containing segment, the cooling segment, and the connected center hole segment and the filter segment are connected in a combiner by 1 piece of tobacco nozzle lining paper. After the connection, a laser perforator provided in the combiner forms a perforation through the mouthpiece liner paper and the cooling segment (paper tube). The perforations had a longitudinal dimension of about 250 μm and a transverse dimension of about 200 μm, and 17 perforations were formed in 1 row at almost equal intervals on the outer circumference of the circle. The proportion of the amount of external gas introduced from the perforations is about 75% relative to the volume of the whole of the gas sucked by the user. Thereby, a non-burning heated smoking article is obtained. For treatingThe ventilation resistance of each segment of the filter segment is 21.8mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described cooling performance evaluation and the above-described sensory evaluation. The results are shown in Table 1.

(example 2)

A non-combustion heating smoking article was produced in the same manner as in example 1, except that a filter segment having an increased cellulose acetate fiber loading was used. The ventilation resistance of each filter segment is 25.0mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described cooling performance evaluation and the above-described sensory evaluation. The results are shown in Table 1.

(example 3)

A non-combustion heating smoking article was produced in the same manner as in example 1, except that a filter segment having an increased cellulose acetate fiber loading was used. The ventilation resistance of each filter section is 30.8mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described cooling performance evaluation and the above-described sensory evaluation. The results are shown in Table 1.

Comparative example 1

A non-combustion heating smoking article was produced in the same manner as in example 1, except that a cylindrical segment not filled with cellulose acetate fibers was used as the filter segment. The ventilation resistance of each filter section is 0.0mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described evaluation of cooling performance.

The results are shown in Table 1.

Comparative example 2

A non-combustion heated smoking article was produced in the same manner as in example 1, except that the length of the filter segment was set to half of the length of the filter segment. The ventilation resistance of each filter section is 10.9mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described evaluation of cooling performance. The results are shown in Table 1.

Comparative example 3

A non-combustion heating smoking article was produced in the same manner as in example 3, except that the length of the filter segment was 2 times. Each filter segmentThe ventilation resistance of the segment is 61.6mmH₂O/seg. The obtained non-combustion heated smoking article was subjected to the above-described evaluation of cooling performance. The results are shown in Table 1.

[ Table 1]

As shown in table 1, it was confirmed that in examples 1 to 3, the maximum temperature of the first suction was sufficiently low, and the aerosol vaporization component was sufficiently cooled. Further, the sensory evaluation results in examples 1 to 3 confirmed that example 2 is suitable for smoking in both of the flavor and sensory temperature, and is most suitable. On the other hand, it was confirmed that the aroma in example 3 was slightly weaker than that in example 2, and the sensory temperature in example 1 was slightly higher than that in example 2, but there was no problem in practical use. In comparative example 3, the maximum temperature of the first suction in the evaluation of cooling performance was sufficiently low, but since the air flow resistance per stage was 2 times that of example 3, it was predicted that the aroma was weaker than that of example 3 in the sensory evaluation.
