Description

The present invention relates to non-combustion heated smoking articles and non-combustion heated smoking systems.

Ordinary combustible smoking articles (tobacco) that smoke using combustion are made of dried tobacco leaves carved to a width of about 1 mm, and a tobacco filling containing fragrances, moisturizers, and appropriate moisture, etc., on paper. It has a tobacco-containing segment wrapped in a columnar shape with a wrapper made of paper, and a mouthpiece segment made of fibers made of cellulose acetate or the like or pleated paper wrapped in a columnar shape with a paper wrapper. The tobacco-containing segment and the mouthpiece segment are connected by a lining paper. Smoking is performed by the user igniting the end of the tobacco-containing segment with a lighter or the like and sucking from the end of the mouthpiece segment. The tip of the tobacco-containing segment burns at a temperature exceeding 800 ° C.

As an alternative to such ordinary combustion smoking articles, non-combustion heated smoking articles and non-combustion heated smoking systems that utilize heating instead of combustion have been developed (for example, Patent Documents 1 to 6). The heating temperature is lower than the combustion temperature of the burning smoking article, for example, heating at 400 ° C. or lower. In non-combustion heated smoking articles, the tobacco filling of the tobacco-containing segment contains an aerosol-forming substrate such as glycerin, propylene glycol (PG), triethylcitrate (TEC), triacetin. The aerosol-forming substrate is vaporized by heating and transferred by suction to the cooling segment within the mouthpiece segment, where it is cooled to further ensure aerosol formation. When suction is performed from the filter segment provided at the end on the mouthpiece side in the mouthpiece segment, the aerosol is also sucked together, so that the user's satisfaction can be ensured.

A non-combustion heated smoking system generally comprises a columnar non-combustion heated smoking article having a shape similar to a normal burning smoking article and a heating device including a battery, a controller, a heater and the like. Examples of the heater include a heater by electric resistance and a heater by IH. As a method of heating the heater by electric resistance, a method of heating with a heater from the outside of the non-combustion heated smoking article, a needle-shaped or blade-shaped heater is placed from the tip of the non-combustion heated smoking article into the tobacco-containing segment containing the tobacco filling. Examples thereof include a method of inserting and heating.

Patent No. 5292410 Patent No. 5771338 Special Table 2013-507906 Gazette International Publication No. 2017/198838 Patent No. 5787618 Special Table 2016-506729

As described above, the aerosol-forming substrate (hereinafter, also referred to as an aerosol vaporization component) vaporized by heating is mainly cooled in the cooling segment, and condensation occurs from the vapor to the particles to become an aerosol. Here, the aerosol vaporization component is required to be sufficiently cooled so that the user can suck it from the filter segment provided at the end on the mouthpiece side. As a cooling segment for non-combustion heating smoking articles, for example, in Patent Document 4, a perforation is provided on the outer periphery of a cylindrical portion of a cavity, outside air is introduced from the perforation at the time of suction, and the aerosol vaporization component and the outside air are brought into contact with each other for cooling. The configuration is disclosed.

However, when the aerosol vaporization component is cooled only by the outside air introduced from the perforations provided in the cooling segment, it is necessary to introduce a large amount of outside air in order to sufficiently perform the cooling, so that the aroma taste is good. It is spoiled. Therefore, it is desired to develop a method capable of sufficiently cooling the aerosol vaporization component without impairing the flavor and taste.

It is an object of the present invention to provide a non-combustion heated smoking article capable of sufficiently cooling an aerosol vaporizing component without impairing the flavor and taste, and a non-combustion heated smoking system including the non-combustion heated smoking article.

The non-combustion heated smoking article according to the present invention is a non-combustion heated smoking article including a tobacco-containing segment containing a tobacco and an aerosol-producing substrate, a tubular cooling segment having a perforation on the circumference, and a filter segment. When smoking is performed from 40 seconds after the start of heating to 5 puffs based on the HCI method (Canada Forced Smoking Condition Law) while closing the perforation and heating the tobacco-containing segment with the following temperature profile, before smoking. The mass increase of the filter segment after smoking is 4.0-7.9 mg;
(Temperature profile)
Hold at 230 ° C. for 50 seconds, hold at 200 ° C. for 130 seconds, and then hold at 170 ° C.

The non-combustion heated smoking system according to the present invention includes the non-combustion heated smoking article and a heating device for heating the tobacco-containing segment.

[Non-combustion heated smoking goods]
The non-combustion heated smoking article according to the present invention includes a tobacco-containing segment containing a tobacco and an aerosol-producing substrate, a tubular cooling segment having perforations on the periphery, and a filter segment. Here, while closing the perforation and heating the tobacco-containing segment with the temperature profile, smoking was performed from 40 seconds after the start of heating to 5 puffs based on the HCI method (Health Canada Intense, Canadian forced smoking condition method). In the case, the mass increase (hereinafter, also simply referred to as “mass increase”) of the filter segment after smoking compared to before smoking is 4.0 to 7.9 mg.

In the present invention, when smoking up to 5 puffs under the above conditions, the mass increase of the filter segment after smoking is 4.0 to 7.9 mg with respect to that before smoking, so that the aerosol vaporization component does not impair the flavor and taste. Can be cooled sufficiently. It is presumed that the mass increase is caused by the trapping of aerosols and water vapor in the filter segment. In the present invention, when the mass increase is 4.0 mg or more, the aerosol and water vapor are sufficiently trapped in the filter segment, so that heat is also trapped. In addition, the captured aerosol and water vapor show a cooling effect. Therefore, these provide a high cooling effect in the filter segment. Further, when the mass increase is 7.9 mg or less, the aerosol is suppressed from being unnecessarily captured, and the tobacco component and the fragrance component contained in the aerosol are sufficiently supplied to the user. The taste is not impaired. Further, even when cooling is performed by the outside air introduced from the perforation provided in the cooling segment, the cooling effect can be obtained in the filter segment, so that the amount of the outside air introduced from the perforation can be reduced and a sufficient flavor and taste can be obtained. Hereinafter, the details of the present invention will be described.

In the present invention, the mass increase is 4.0 to 7.9 mg, preferably 5.0 to 7.5 mg, and more preferably 6.0 to 7.0 mg. As will be described later, the mass increase can be appropriately adjusted by, for example, the material of the filling material to be filled in the filter segment, the filling amount, the aeration resistance of the filter segment, and the like. As described above, the mass increase is considered to be caused by the trapping of aerosols and water vapor in the filter segment, and the mass increase increases as the number of puffs increases.

The mass increase can be measured by the following method. The filter segment of the non-combustion heated smoking article with the perforations provided in the cooling segment closed is connected to the smoker via a tube. The tobacco-containing segment of the non-combustion-heated smoking article is heated by a heater and sucked by the smoking machine. Heating by the heater is held at 230 ° C. for 50 seconds, held at 200 ° C. for 130 seconds, and then held at 170 ° C. These temperatures indicate the set temperature of the heater. Suction starts 40 seconds after the start of heating and is 55 ml / 2 seconds per puff based on the HCI method (Canada Forced Smoking Condition Law) (1 puff is at 30 second intervals, that is, sucks for 2 seconds and waits for 28 seconds. That), perform a total of 5 puffs. 5 Remove the filter segment from the non-combustible heated smoking article after puffing and measure its mass. The mass increase is calculated by subtracting the mass of the filter segment of the non-combustion heated smoking article before smoking from the mass. The HCI method is a method indicated by the Canadian Ministry of Insurance and is described in Haelth Canada-Tobacco Reporting Regulation SOR / 2000-273. The purpose of the evaluation test with the perforation closed is to eliminate cooling by the air introduced from the perforation and to evaluate the cooling capacity of the filter segment alone, and in the HCI method, it is necessary to close the perforation and suck. This is because it is defined as one of the above.

FIG. 1 shows an example of a non-combustion heated smoking article according to the present invention. The non-combustion heated smoking article 20 shown in FIG. 1 includes a tobacco-containing segment 1 and a mouthpiece segment 2. The mouthpiece segment 2 includes a cooling segment 3, a center hole segment 4, and a filter segment 5. During smoking, the tobacco-containing segment 1 is heated and suction is performed from the end of the filter segment 5. The positions of the cooling segment 3 and the center hole segment 4 may be exchanged, or the positions of the center hole segment 4 and the filter segment 5 may be exchanged. Further, the mouthpiece segment 2 does not have to have the center hole segment 4.

The tobacco-containing segment 1 has a tobacco filling 6 containing tobacco, an aerosol-forming substrate, and a tubular wrapper 7 covering the tobacco filling 6. The tobacco filling 6 may further contain a volatile fragrance component and water. There are no particular restrictions on the size of the tobacco used as the filling material or the method for preparing the tobacco. For example, dried tobacco leaves may be chopped to a width of 0.8 to 1.2 mm. When carved to the above width, the length of the carving is about 5 to 20 mm. Further, dried tobacco leaves may be crushed to have an average particle size of about 20 to 200 μm, homogenized, and sheet-processed, which may be chopped to a width of 0.8 to 1.2 mm. .. When carved to the above width, the length of the carving is about 5 to 20 mm. Further, the above-mentioned sheet-processed product that has been gather-processed without being chopped may be used as the filling material. Further, a plurality of sheets molded into a cylindrical shape may be arranged concentrically. Various types of tobacco contained in the tobacco filling can be used, whether the dried tobacco leaves are chopped and used as a crushed and homogenized sheet. Yellow varieties, Burley varieties, Orient varieties, native varieties, and other Nicotiana-Tabacam varieties and Nicotiana rustica varieties can be appropriately blended and used to obtain the desired taste. Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Academic Studies Center, March 31, 2009".

There are a plurality of conventional methods for crushing tobacco and processing it into a homogenized sheet. One is a papermaking sheet made using a papermaking process, and two are homogenized by mixing with an appropriate solvent such as water, and then the homogenized product is thinly cast on a metal plate or metal plate belt. It is a cast sheet made by drying, and three are rolled sheets that are homogenized by mixing with an appropriate solvent such as water and extruded into a sheet shape. Details of the types of the homogenized sheet are disclosed in "Tobacco Encyclopedia, Tobacco Academic Studies Center, 2009.3.31".

The above is usually 520 mg / cm ³ or less, preferably 420 mg / cm ³ or less. Specifically, the range of the content of the tobacco filler 6 in the tobacco-containing segment 1 can be 200 to 450 mg per tobacco-containing segment 1 in the case of the tobacco-containing segment 1 having a circumference of 22 mm and a length of 20 mm. 280-400 mg is preferable.

In addition, these volatile fragrance components may be used alone or in combination of two or more.

The content of the aerosol-forming substrate in the tobacco filling 6 is not particularly limited, and is usually 5 to 50% by mass, preferably 10 to 10 to 50% by mass, from the viewpoint of sufficiently producing an aerosol and imparting a good taste. It is 20% by mass. When the tobacco filling 6 contains a volatile flavor component, the content of the volatile flavor component in the tobacco filling is not particularly limited, and from the viewpoint of imparting a good taste, 10000 ppm with respect to the amount of the normal tobacco filling substance. It is more than 20,000 ppm, more preferably 25,000 ppm or more, usually 50,000 ppm or less, preferably 40,000 ppm or less, and more preferably 33,000 ppm or less.

The method of filling the tobacco filling 6 in the wrapper 7 is not particularly limited, but for example, the tobacco filling 6 may be wrapped in the wrapper 7, or the tubular wrapper 7 may be filled with the tobacco filling 6. When the shape of the tobacco has a longitudinal direction such as a rectangular shape, the tobacco may be filled so that the longitudinal direction is an unspecified direction in the wrapper 7, and the tobacco-containing segment 1 may be filled in the axial direction or the tobacco-containing segment 1. It may be filled by aligning it so as to be perpendicular to the axial direction. When the tobacco-containing segment 1 is heated, the tobacco component, aerosol-forming substrate and water contained in the tobacco filling 6 are vaporized, and these are transferred to the mouthpiece segment 2 by suction.

The cooling segment 3 is composed of a tubular member 8. The tubular member 8 can be, for example, a paper tube obtained by processing thick paper into a cylindrical shape. The tubular member 8 and the mouthpiece lining paper 15 described later are provided with a perforation 9 penetrating both of them. The presence of the perforations 9 introduces outside air into the cooling segment 3 during suction. As a result, the aerosol vaporization component generated by heating the tobacco-containing segment 1 comes into contact with the outside air, and the temperature drops, so that the aerosol is liquefied to form an aerosol. The diameter (crossing length) of the perforation 9 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 9 is not particularly limited, and may be one or two or more. For example, a plurality of holes 9 may be provided on the periphery of the cooling segment 3. The amount of outside air introduced from the perforation 9 is preferably 85% by volume or less, more preferably 80% by volume or less, based on the total volume of the gas sucked by the user. When the ratio of the amount of outside air is 85% by volume or less, it is possible to sufficiently suppress the reduction of flavor and taste due to dilution by the outside air. From the viewpoint of cooling performance, the lower limit of the range of the ratio of the amount of outside air is preferably 55% by volume or more, more preferably 60% by volume or more.

The center hole segment is composed of a packed bed having one or more hollow portions and an inner plug wrapper covering the packed bed. For example, the center hole segment 4 is composed of a first packed layer 10 having a hollow portion and a first inner plug wrapper 11 that covers the first packed layer 10. The center hole segment 4 has a function of increasing the strength of the mouthpiece segment 2. The first packed layer 10 has an inner diameter of φ5.0 to φ1.0 mm, for example, which is packed with cellulose acetate fibers at a high density and is hardened by adding 6 to 20% by mass of a plasticizer containing triacetin to the mass of cellulose acetate. Can be a rod of. Since the packed bed 10 of the first packed bed has a high packing density of fibers, air and aerosol flow only in the hollow portion at the time of suction, and hardly flow in the packed bed 10 of the first packed bed. Since the first packed bed 10 inside the center hole segment 4 is a fiber packed bed, the feeling of touch from the outside during use is less likely to cause discomfort to the user. The center hole segment 4 may not have the first inner plug wrapper 11 and its shape may be maintained by thermoforming.

The configuration of the filter segment in the present invention is not particularly limited, but is composed of a second packed layer 12 and a second inner plug wrapper 13 that covers the second packed layer 12, for example, as in the filter segment 5 of FIG. Will be done. Since the second packed bed 12 is present up to the end of the filter segment 5, the end has the same appearance as a normal combustion smoking article.

The material of the packed material in the second packed bed 12 can be appropriately selected so that the mass increase is within the range according to the present invention. Examples of the material of the filler include a cellulose acetate fiber bundle to which a plasticizer (triacetin) is added, paper using pulp as a main raw material, and the like. These fillers may be used alone or in combination of two or more.

Further, the ventilation resistance per segment of the filter segment 5 can be appropriately selected so that the mass increase is within the range according to the present invention. When the aeration resistance is high, aerosol and water vapor are more trapped in the filter segment 5, so that the increase in mass becomes large. The aeration resistance per segment is preferably 15 to 60 mmH ₂ O / seg, more preferably 20 to 40 mmH ₂ O / seg, and even more preferably 25 to 30 mmH ₂ O / seg. For example, when the length of the filter segment 5 in the axial direction (horizontal direction in FIG. 1) is 7 mm, the ventilation resistance per segment is preferably 15 to 60 mmH ₂ O / 7 mm. The aeration resistance per segment can be appropriately changed depending on the amount of the filler filled in the filter segment 5, the material, and the like. For example, when the filler is cellulose acetate fiber, the aeration resistance can be increased by increasing the amount of the cellulose acetate fiber filled in the filter segment 5. When the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber can be 0.13 to 0.18 g / cm ³ . The ventilation resistance is a value measured by a ventilation resistance measuring device (trade name: SODIMAX, manufactured by SODIM).

The peripheral length of the filter segment 5 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The length of the filter segment 5 in the axial direction (horizontal direction in FIG. 1) can be selected from 4 to 10 mm, and the ventilation resistance thereof can be selected to be 15 to 60 mmH ₂ O / seg. The axial length of the filter segment 5 is preferably 5 to 9 mm, more preferably 6 to 8 mm. The shape of the cross section of the filter segment 5 is not particularly limited, but may be, for example, a circle, an ellipse, a polygon, or the like. Further, destructive capsules containing fragrance, fragrance beads, and fragrance may be directly added to the filter segment 5.

The center hole segment 4 and the filter segment 5 are connected by an outer plug wrapper 14. The outer plug wrapper 14 can be, for example, cylindrical paper. Further, the tobacco-containing segment 1, the cooling segment 3, and the connected center hole segment 4 and filter segment 5 are connected by a mouthpiece lining paper 15. These connections can be made by, for example, applying glue such as vinyl acetate glue to the inner side surface of the mouthpiece lining paper 15, inserting the three segments, and winding them. In addition, these segments may be connected in a plurality of times by a plurality of lining papers.

The axial length of the non-combustion heated smoking article according to the present invention, that is, the horizontal length in FIG. 1 is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and more preferably 50 mm to 60 mm. Is more preferable. The circumference of the non-combustion heating type smoking article is preferably 16 mm to 25 mm, more preferably 20 mm to 24 mm, and even more preferably 21 mm to 23 mm. For example, the length of the tobacco-containing segment 1 is 20 mm, the length of the cooling segment 3 is 20 mm, the length of the center hole segment 4 is 8 mm, and the length of the filter segment 5 is 7 mm. The length of the filter segment 5 can be selected within the range of 4 to 10 mm. Further, the ventilation resistance of the filter segment 5 at that time can be selected so as to be 15 to 60 mmH ₂ O / seg per segment. The lengths of these individual segments can be appropriately changed according to manufacturing aptitude, required quality, and the like. Furthermore, even if only the filter segment is arranged on the downstream side of the cooling segment without using the center hole segment, it can function as a non-combustion heated smoking article.

[Non-combustion heating smoking system]
The non-combustion heated smoking system according to the present invention includes a non-combustion heated smoking article according to the present invention and a heating device for heating a tobacco-containing segment. Since the non-combustion heated smoking system includes the non-combustion heated smoking article according to the present invention, the aerosol vaporization component can be sufficiently cooled without impairing the flavor and taste. The non-combustion heated smoking system according to the present invention is not particularly limited as long as it includes the non-combustion heated smoking article according to the present invention and the heating device, and may have other configurations.

FIG. 2 shows an example of the non-combustion heated smoking system according to the present invention. The non-combustion heated smoking system shown in FIG. 2 includes a non-combustion heated smoking article 20 according to the present invention and a heating device 21 for heating the tobacco-containing segment of the non-combustion heated smoking article 20 from the outside. FIG. 2A shows a state before the non-combustion heated smoking article 20 is inserted into the heating device 21, and FIG. 2B shows a state where the non-combustion heated smoking article 20 is inserted into the heating device 21 and heated. ..

The body 22 has a cylindrical recess 27, and the heater 23 and the metal tube 24 are located on the inner side surface of the recess 27 at a position corresponding to the tobacco-containing segment of the non-combustion heated smoking article 20 inserted into the recess 27. Have been placed. The heater 23 can be a heater by electric resistance, and electric power is supplied from the battery unit 25 according to an instruction from the control unit 26 that controls the temperature, and the heater 23 is heated. The heat generated from the heater 23 is transferred to the tobacco-containing segment of the non-combustion heated smoking article 20 through the metal tube 24 having high thermal conductivity. In FIG. 2B, since it is schematically shown, there is a gap between the outer circumference of the non-combustion heated smoking article 20 and the inner circumference of the metal tube 24, but in reality, heat is efficiently transferred. For the purpose, it is desirable that there is no gap between the outer circumference of the non-combustion heated smoking article 20 and the inner circumference of the metal tube 24. The heating device 21 heats the tobacco-containing segment of the non-combustion heated smoking article 20 from the outside, but may be heated from the inside.

The heating temperature indicates the temperature of the heater of the heating device.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples.

(Measurement of mass increase of filter segment before and after smoking and evaluation of cooling performance)
A filter segment of a non-combustion heated smoking article with closed perforations provided in the cooling segment was connected to the smoker via a tube. In addition, thermocouples were placed before and after the filter segment. The tobacco-containing segment of the non-combustion heated smoking article was heated by a heater and sucked by the smoking machine. The heating by the heater was held at 230 ° C. for 50 seconds, held at 200 ° C. for 130 seconds, and then held at 170 ° C. Suction starts 40 seconds after the start of heating and is 55 ml / 2 seconds per puff based on the HCI method (Canada Forced Smoking Condition Law) (1 puff is at 30 second intervals, that is, sucks for 2 seconds and waits for 28 seconds. That), I went a total of 5 puffs.

The filter segment was removed from the non-combustible heated smoking article after 5 puffs and its mass was measured. The mass of the filter segment of the non-combustion heated smoking article before smoking was subtracted from the mass, and the mass increase of the filter segment before and after smoking was calculated. The results are shown in Table 1.

In addition, in order to evaluate the cooling performance, from the maximum temperature ( _Ta ) detected by the thermocouple placed in front of the filter segment to the maximum temperature detected by the thermocouple placed after the filter segment in each puff. The value ΔT (= _{Ta −T b )} obtained by subtracting (T _b ) was calculated. The results are shown in FIG. Table 1 shows the value of ΔT ₁ , which is ΔT of the first puff. Since the aerosol temperature of the first puff is the highest, it is preferable that ΔT ₁ is large.

(sensory evaluation)
Non-combustion heated smoking articles with filter segments with perforations provided in the cooling segment were smoked by four well-trained panelists at the same smoking intervals as the mass gain measurements and sensory assessment (flavor, taste, taste,). Evaluation of sensory temperature) was performed. The sensory evaluation was performed according to the following criteria.
A: Suitable for smoking in terms of both flavor and sensory temperature.
B: Although it is suitable for smoking at a sensory temperature, its flavor is slightly weak.
C: The taste is good for smoking, but the sensory temperature is not suitable.

(Example 1)
The following tobacco-containing segments, cooling segments, centerhole segments, and filter segments were prepared.

<Tobacco-containing segment>
The tobacco sheet produced by the papermaking process was cut to a width of 0.8 mm, and 16% by mass of glycerin was added as an aerosol-forming substrate to obtain a tobacco filling. The length in the vertical direction when cut to a width of 0.8 mm was about 5 mm to 20 mm. The water content of the tobacco filling was about 12% by mass. The tobacco filling was wrapped with a wrapper containing wood pulp as a main component and having a basis weight of 35 g / m ² and a thickness of 50 μm to produce a tobacco-containing segment. A normal cigarette making machine was used as a device for winding. The tobacco-containing segment was columnar, with a circumference of 22 mm and an axial length of 20 mm. The tobacco filling wrapped with the wrapper was filled in the rod in random directions. The mass of the tobacco filling in the tobacco-containing segment was 280 mg / seg.

<Cooling segment>
A cooling segment, which is a paper tube, was manufactured using thick paper having a basis weight of 100 g / m ² and a thickness of 125 μm using a paper tube manufacturing device manufactured by Hani. The cooling segment was columnar, with a circumference of about 21.75 mm and an axial length of 20 mm. Further, since the paper tube manufacturing apparatus is a mechanism in which two sheets of thick paper are laminated to form a paper tube, the thickness of the obtained cooling segment is about 250 μm.

<Center hall segment>
A hollow centerhole segment is manufactured using a centerhole segment manufacturing device manufactured by Hani, using a cellulose acetate fiber bundle as a filler and triacetin for adhering cellulose acetate fibers to each other to ensure segment hardness as a plasticizer. did. The single fineness of the cellulose acetate fiber bundle was 8.0 denier, the total fineness was 40,000 denier, and the cross-sectional shape of the fiber was a Y cross section. Triacetin in an amount of 15% by mass based on the cellulose acetate fiber bundle was sprayed onto the cellulose acetate fiber bundle. The center hole segment was columnar, with a circumference of about 21.5 mm and an axial length of 8 mm. Further, one hollow portion having an inner diameter of about φ5 mm was formed in the central portion of the cylinder. The center hole segment was prepared as a so-called "non-wrap rod" without using a wrapper for winding the cellulose acetate fiber bundle. The packing density of the cellulose acetate fiber bundle filled in the hollow shape was 0.280 g / cm ³ .

<Filter segment>
A solid filter segment was produced by using a filter manufacturing apparatus manufactured by Hauni using a cellulose acetate fiber bundle as a filler and triacetin for adhering cellulose acetate fibers to each other to ensure segment hardness as a plasticizer. The cellulose acetate fiber bundle sprayed with triacetin was wrapped with an inner plug wrapper having a basis weight of 27 g / m ² by a filter manufacturing apparatus. The cellulose acetate fiber bundle had a single fineness of 5 denier, a total fineness of 35000 denier, and a fiber cross-sectional shape of Y cross-section. Triacetin in an amount of 6% by mass based on the cellulose acetate fiber bundle was sprayed onto the cellulose acetate fiber bundle. The filter segment was columnar, with a circumference of about 21.5 mm and an axial length of 7 mm. The packing density of the cellulose acetate fiber bundle was 0.135 g / cm ³ .

The center hole segment and the filter segment were connected by an outer plug wrapper. The tobacco-containing segment, the cooling segment, and the connected centerhole segment and filter segment were connected by a single mouthpiece lining paper in a combiner. After connection, a laser perforator installed in the combiner was used to form a perforation through the mouthpiece lining paper and the cooling segment (paper tube). The perforations had a shape of about 250 μm in length and about 200 μm in width, and 17 perforations were formed in a row on the circumference at approximately equal intervals. The ratio of the amount of outside air introduced from the perforation to the total volume of gas sucked by the user was about 75%. As a result, a non-combustion heated smoking article was obtained. The aeration resistance per segment of the filter segment was 21.8 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured, the cooling performance was evaluated, and the sensory evaluation was performed. The results are shown in Table 1 and FIG.

(Example 2)
A non-combustion heated smoking article was produced in the same manner as in Example 1 except that a filter segment having an increased amount of cellulose acetate fibers filled was used. The aeration resistance per segment of the filter segment was 25.0 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured, the cooling performance was evaluated, and the sensory evaluation was performed. The results are shown in Table 1 and FIG.

(Example 3)
A non-combustion heated smoking article was produced in the same manner as in Example 1 except that a filter segment having an increased amount of cellulose acetate fibers filled was used. The aeration resistance per segment of the filter segment was 30.8 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured, the cooling performance was evaluated, and the sensory evaluation was performed. The results are shown in Table 1 and FIG.

(Comparative Example 1)
A non-combustion heated smoking article was produced in the same manner as in Example 1 except that a tubular segment not filled with cellulose acetate fiber was used as the filter segment. The aeration resistance per segment of the filter segment was 0.0 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured and the cooling performance was evaluated. The results are shown in Table 1 and FIG.

(Comparative Example 2)
A non-combustion heated smoking article was prepared in the same manner as in Example 1 except that the length of the filter segment was halved. The aeration resistance per segment of the filter segment was 10.9 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured and the cooling performance was evaluated. The results are shown in Table 1 and FIG.

(Comparative Example 3)
A non-combustion heated smoking article was produced in the same manner as in Example 3 except that the length of the filter segment was doubled. The aeration resistance per segment of the filter segment was 61.6 mmH ₂ O / seg. Using the obtained non-combustion heated smoking article, the mass increase was measured and the cooling performance was evaluated. The results are shown in Table 1 and FIG.

As shown in Table 1, it was confirmed that the value of ΔT ₁ was sufficiently large in Examples 1 to 3 and the aerosol vaporization component was sufficiently cooled. In addition, as a result of sensory evaluation in Examples 1 to 3, it was confirmed that Example 2 is suitable for smoking in terms of both flavor and sensory temperature, and is optimal. On the other hand, it was confirmed that the aroma taste was slightly weaker than that of Example 2 in Example 3 and the sensory temperature was slightly higher than that of Example 2 in Example 1, but there was no problem in practical use. Although the value of ΔT ₁ is sufficiently large in Comparative Example 3, the aeration resistance per segment is twice that of Example 3, so that the aroma taste is even weaker than that of Example 3 when the sensory evaluation is performed. is expected.
