[Reference form]
The cigarette reference form will be described below. In this reference form, the perfume capsule may be directly embedded in the filter medium constituting the filter (first aspect), or may be disposed in a hollow portion formed between a plurality of filter plugs (second embodiment). Embodiment).

As shown in FIG. 1, a cigarette 11 according to a first aspect of the reference embodiment includes a tobacco rod 14 including a tobacco filler 12 (cut leaves, tobacco) and a wrapping paper 13 wound around the tobacco filler 12, and a tobacco. The filter 15 provided adjacent to the rod 14 and the tip paper 16 wound on the tobacco rod 14 and the filter 15 so as to be connected across the tobacco rod 14 and the filter 15 are included.

The filter 15 is located in a single filter plug 17, a filter wrapping paper 21 wound around the filter plug 17, embedded in the filter 15 (in the filter plug 17), and contains a fragrance in the film 22. And a fragrance capsule 23 for holding the content liquid. In the first embodiment, at least one of the filter wrapping paper 21 and the chip paper 16 has a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm.

As shown in FIG. 2, the cigarette 11 according to the second aspect of the reference embodiment includes a cigarette filler 12 and a cigarette rod 14 including a wrapping paper 13 wound around the cigarette filler 12, a filter 15, and a cigarette rod 14. And a cigarette rod 14 and a chip paper 16 wound on the filter 15 so as to connect them across the filter 15.

The filter 15 includes two filter plugs 17 that are spaced apart from each other via the hollow portion 24, and the two filter plugs 17 are disposed around the two filter plugs 17 so as to form a hollow portion 24 between the filter plugs 17. The filter wrapping paper 21 wound around and the fragrance capsule 23 which is located in the hollow portion 24 and holds the content liquid containing the fragrance in the coating film 22 are included.

In the second embodiment, at least one of the filter wrapping paper 21 and the chip paper 16 has a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm.

The following is a description of the above two aspects unless otherwise specified.

Paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm has a higher density and thickness than the paper generally used for the filter wrapping paper 21 and the chip paper 16, With such density and thickness, it has high capsule crushing performance.

In this specification, the density of paper is measured by the methods specified in JIS P 8124 and JIS P 8118, respectively. It refers to the value obtained by fitting. That is, “density (g / cm ³ ) = basis weight (g / m ² ) / thickness (mm) × 1000 (formula 2)”.

When paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is used as the filter wrapping paper 21, the chip paper 16 has a density of 0.5 to 1.0 g / cm ³ . A paper having a density and a thickness of 100 to 250 μm may be used, or a paper having a normal density and thickness generally used as the chip paper 16 may be used. Similarly, when a paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is used as the chip paper 16, the filter wrapping paper 21 has a thickness of 0.5 to 1.0 g / cm ^3. A paper having a density of 100 to 250 μm and a thickness of 100 to 250 μm may be used, or a paper having a normal density and thickness generally used as the filter wrapping paper 21 may be used.

In this preferred embodiment, at least one of the paper filter wrapping paper 21 and tipping paper 16, having a density and 100 to the thickness of 250μm of 0.5 ~ 1.0 g / cm ^3, preferably 0.7 to It has a density of 1.0 g / cm ³ and a thickness of 180-250 μm, more preferably a density of 0.8-1.0 g / cm ³ and a thickness of 240-250 μm.

Even if the thickness of the paper is in the range of 100 to 250 μm, if the density is less than 0.5 g / cm ³ , the paper is easily deformed and broken when the fragrance capsule 23 is crushed, and the pressure on the finger is locally Therefore, the fragrance capsule 23 is less likely to be crushed. Further, if the density is larger than 1.0 g / cm ³ , it is not preferable because the manufacturing cost of paper increases. The density of the paper is preferably large in the range of 0.5 to 1.0 g / cm ³ in order to prevent the capsule content liquid from leaking out.

Even if the density of the paper is within the range of 0.5 to 1.0 g / cm ³ , if the thickness is less than 100 μm, the paper is easily deformed and broken when the fragrance capsule 23 is crushed, and the pressure applied to the finger However, the perfume capsules 23 are less likely to be crushed. Moreover, when thickness is larger than 250 micrometers, while it becomes difficult to perform the winding process of cigarette manufacture, it becomes difficult to obtain the touch which broke the fragrance | flavor capsule 23.

The filter wrapping paper 21 in the first embodiment is also called a web, and similarly, when a paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is adopted for the web, the basis weight is 50 to 250 g / m ² , and air permeability can be 0 to 30000 CU. In the first aspect, the air permeability of the filter wrapping paper 21 can be set to 0 for the purpose of preventing the liquid in the fragrance capsule 23 from leaking out of the cigarette 11.

The filter wrapping paper 21 in the second aspect is also called a molded paper. When paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is adopted for the filter wrapping paper 21, generally the basis weight is 50 to 250 g / m ² and the air permeability is 0 to 30000 CU. It can be. In the second aspect, since the fragrance capsule 23 is located in the hollow portion 24 of the filter 15, the air permeability of the filter wrapping paper 21 is set to 0 for the purpose of preventing the liquid in the fragrance capsule 23 from seeping out of the cigarette 11. It is particularly preferable to do this. When paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is adopted for the filter wrapping paper 21, the chip paper 16 is generally used as the chip paper 16 and has a normal density and thickness. A paper having In this case, the basis weight of the tipping paper 16 for example, a 20 ~ 60g / ^{m 2,} the thickness of, for example, can be set to 20 ~ 60 [mu] m.

In the first aspect of the present embodiment, the fragrance capsule 23 is embedded in the filter plug 17, and in the second aspect, the fragrance capsule 23 is accommodated in the hollow portion 24 between the filter plugs 17. One perfume capsule 23 may be present in the filter 15, or a plurality (for example, 2 to 10) of perfume capsules 23 may be present. When the fragrance capsule 23 is accommodated in the hollow portion 24, one fragrance capsule 23 may be accommodated per one hollow portion 24, or a plurality of (for example, 2 to 10) fragrance capsules 23 may be accommodated. It may be accommodated.

The fragrance capsule 23 is composed of a film 22 and a content liquid 25 containing the fragrance. For the film 22, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride, and the like can be used, and a flavor and a colorant can be further included. The fragrance capsule 23 is preferably colored so that a smoker can recognize it when crushing the fragrance capsule 23 even when surrounded by the filter wrapping paper 21 and the chip paper 16 having opacity. For example, it is preferable to include Blue No. 1 or the like.

As a fragrance | flavor of the content liquid 25, arbitrary fragrance | flavors used for smoking articles, such as a menthol and a plant essential oil, can be used, for example. Main flavors include menthol, leaf tobacco extract, natural plant flavors (eg cinnamon, sage, herbs, chamomile, kuzukusa, sweet tea, clove, lavender, cardamom, clove, nutmeg, bergamot, geranium, honey essence, rose Oil, lemon, orange, cinnamon, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang ylang, fennel, anise, licorice, st john's bread , Plum extract, peach extract, etc.), sugar (eg, glucose, fructose, isomerized sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (eg, isoamyl acetate, linalyl acetate, propi) Isoamyl acid, linalyl butyrate, etc.), ketones (eg, menthone, ionone, damacenone, ethyl maltol, etc.), alcohols (eg, geraniol, linalool, anethole, eugenol, etc.), aldehydes (eg, vanillin, benzaldehyde, anise) Aldehydes), lactones (eg, γ-undecalactone, γ-nonalactone, etc.), animal flavors (eg, musk, ambergris, civet, castrium), hydrocarbons (eg, limonene, pinene, etc.) Can be mentioned. These fragrances may be used alone or in combination.

As the solvent of the content liquid 25, a solvent suitable for a fragrance can be used, and medium chain fatty acid triglyceride (MCT) (specifically, tricapryl / glyceryl caprate), propylene glycol, water, ethanol, etc. can be used. it can. The content liquid 25 may further contain other additives such as other solvents, pigments, emulsifiers, and thickeners.

Although the manufacturing method of the fragrance | flavor capsule 23 is not specifically limited, For example, if the dripping method is used, the fragrance | flavor capsule 23 which has the seamless membrane | film | coat 22 can be manufactured. In this method, by using a double nozzle and simultaneously discharging the content liquid 25 from the inner nozzle and the liquid film substance from the outer nozzle, the film liquid can wrap the content liquid without having a seam.

The fragrance capsule 23 can have, for example, a spherical or cylindrical shape, and the sphere includes both a sphere having a substantially circular cross section and an ellipsoid having a elliptical cross section. The perfume capsule 23 preferably has a spherical shape with a substantially circular cross section. In the case of a sphere having a substantially circular cross section, the fragrance capsule 23 can have a diameter of 1.0 to 8.0 mm, for example, and in the case of an ellipsoid, the fragrance capsule 23 has a maximum diameter of 1.0 to 7.0 mm and a minimum diameter of 1. In the case of a cylindrical body, the diameter of the circle may be 1.0 to 7.0 mm and the height may be 1.0 to 7.0 mm. From Example 3 described later, if the size of the fragrance capsule 23 is too small, the pushing distance when the fragrance capsule 23 is crushed becomes longer. Therefore, in the case of a sphere, the diameter is more preferably 3.0 mm or more. In this case, the minimum diameter is more preferably 3.0 mm or more, and in the case of a cylindrical body, the diameter of the circle is more preferably 3.0 mm or more.

Further, the perfume capsule 23 itself is preferably one that can be broken with a strength of about 10 to 35 [N]. Using paper with a density of 0.5-1.0 g / cm ³ and a thickness of 100-250 μm breaks with relatively hard capsules, eg strengths above about 25 [N] and below about 30 [N] Capsules that can be made can also be crushed with a small force and a short indentation distance. Harder capsules have the advantage that the encapsulated cigarette 11 is less likely to break when exposed to high temperatures or when transported.

As demonstrated in a reference example described later, when a capsule that can be broken at a strength of about 30 [N] is directly crushed with a finger or crushed from a molded paper (50NFB), local finger pressure is felt. However, when crushed from the top of a paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm, the perfume capsule can be easily crushed without feeling local finger pressure. It is.

In the first aspect and the second aspect of the reference form, the filter plug 17 can be made of a filter medium of acetate tow, like a normal cigarette with a filter. The filter plug 17 may be composed only of a filter medium, or may be composed of a filter medium and a plug web wound around the filter medium. When the filter 15 includes a plurality of filter plugs 17, the cigarette-side filter plug 17 and the suction-side filter plug 17 may have the same material and structure, or may have different materials and structures. Also good.

Acetate tow has, for example, a single yarn fineness of 1.9 to 12.0 (g / 9000m), a total fineness of 10,000 to 44000 (g / 9000m), a number of fibers of 830 to 23500 (piece), and a ventilation resistance of 100 to 600 (mmH2O / 120mm). A plasticizer such as triacetin may be added to acetate tow, and the plasticizer can be added in an amount of 6 to 10% by weight based on the weight of acetate tow. When activated carbon is added to acetate tow, The plasticizer can be added in an amount of 2 to 20% by weight based on the weight of acetate tow.

If the filter medium is too hard, the repulsive force by the filter plug 17 when the filter containing the fragrance capsule is crushed with a finger is increased, so that the single yarn fineness is more preferably 3.0 (g / 9000 m) or more. Is more preferably 35000 (g / 9000 m) or less.

The filter 15 has a circumference of, for example, about 14 to 26 mm, and the length can be, for example, 17 to 31 mm, as in a normal filter. In the filter 15 of the first embodiment, the length of the hollow portion 24 may be equal to or larger than the size of the fragrance capsule 23, for example, 3 to 7 mm, and the length of each filter plug 17 may be 5 to 20 mm.

In the cigarette 11 of the second mode shown in FIG. 2, two filter plugs 17 are arranged through one hollow portion 24, but n (n is an integer of 2 or more) filter plugs 17 are (n− 1) The hollow portions 24 may be arranged, for example, n is 2 to 4, preferably n is 2 to 3, and more preferably n is 2.

In the embodiment of the present embodiment, the cigarette rod 14 is composed of the cigarette filler 12 and the cigarette paper 13 wound around the cigarette filler 12 as in the case of the normal cigarette 11. For example, the cigarette rod 14 has a circumference of about 14 to 26 mm and 53 to 67 mm. Can have a length.

[Reference Example]
Example 1: Effect of paper thickness and density on indentation distance when crushing perfume capsules In this example, the following six types of test papers were used (the parentheses are the source of each test paper). The characteristics of each test paper are shown in Table 1 below. Each test paper was 2 cm square and used for the experiment.

(1) 50NFB (Nippon Paper Papillia Co., Ltd.)
(2) HS (Shinyodogawa Paper Co., Ltd.)
(3) AT (Shinyodogawa Paper Co., Ltd.)
(4) HS120 (Shinyodogawa Paper Co., Ltd.)
(5) S80 (Nippon Paper Papillia Co., Ltd.)
(6) Resistance paper (Nippon Paper Papillia Co., Ltd.)
In FIG. 3, “breaking strength” represents a load [N] applied to the fragrance capsule when the fragrance capsule is broken, and “movement distance” represents an indentation distance [mm] when the fragrance capsule is broken. Represents. In addition, the basic weight of 50NFB is 50.0 g / m < ² >.

The perfume capsule 23 was prepared by mixing the film substance (15% by weight) and the content liquid 25 (85% by weight), and dropping the mixture. The main components of the coating substance and the content liquid constituting the fragrance capsule 23 were as follows.
(I) Coating material Gelatin, gellan gum, starch, glycerin, and sorbitol (ii) Contents liquid Medium chain fatty acid triglyceride (tricapryl / glycol caprate) (83 wt%)

The prepared fragrance capsule 23 was a sphere having a diameter of about 4.5 mm. The flavor capsule 23 had a hardness of about 30N. In the present embodiment, the content liquid 25 of the fragrance capsule 23 is composed of only the solvent and does not contain the fragrance, but it has been demonstrated that the presence or absence of the fragrance does not affect the ease of crushing the capsule.

Using the measurement system 26 shown in FIG. 4, the relationship between the indentation distance and the load when the fragrance capsule 23 was crushed was examined. That is, a fragrance capsule was placed on a test paper placed on an elastic rubber, and the fragrance capsule was crushed by applying pressure from above with a pressure sensitive shaft of a rheometer. The indentation distance (mm) (also referred to as the movement distance) and the load (N) at that time were measured. The measurement was performed using a Sun RHEO METER CR3000EX (Sun Science Co., Ltd.).

The measurement results are shown in FIG. In FIG. 5, (1) is 50NFB, (2) is HS, (3) is AT, (4) is HS120, (5) is S80, (6) is resistance paper.

5 that HS, AT, HS120, and S80 have a smaller pushing distance (moving distance) required to reach the same load than test paper 50NFB. On the other hand, the resistance paper has a larger pressing distance (movement distance) necessary to reach the same load than 50 NFB. FIG. 6 schematically shows the state when the same load is applied to 50 NFB, resistance paper, and S80. FIG. 6 shows that when paper having a predetermined density and thickness, such as S80, is used, the same load can be applied to the perfume capsule 23 with a smaller pushing distance, and the paper is not easily broken when the load is applied. It shows that the pressure at the time of crushing the fragrance | flavor capsule 23 can be disperse | distributed to a wider contact surface. On the other hand, in FIG. 6, when a low density paper (resistance paper) or a low thickness paper (50NFB) is used, the pushing distance required to give a predetermined load is large, and the paper is not loaded when a load is applied. Since it is easy to break, it shows that the pressure at the time of crushing the fragrance | flavor capsule 23 tends to concentrate on one point.

Based on these results, the relationship between the thickness of the paper and the ease of transmission of the force to the fragrance capsule 23 is shown in FIG. In FIG. 7, the horizontal axis indicates the paper thickness [μm], and the vertical axis indicates the breaking strength [N] / movement distance [mm]. Here, “destructive strength” means a load [N] applied to the fragrance capsule 23 when the fragrance capsule 23 is broken, and “movement distance” is an indentation distance when the fragrance capsule 23 is broken [ mm]. A large breaking strength [N] / moving distance [mm] means that a large load can be applied to the fragrance capsule 23 with a small pushing distance, that is, it is easy to transmit a force to the fragrance capsule 23 with a small pushing distance. In FIG. 7, (1) is 50NFB, (2) is HS, (3) is AT, (4) is HS120, (5) is S80, (6) is resistance paper. In addition, the graph of FIG. 7 prepares 20 samples for each test paper, measures the indentation distance (mm) and the load (N), and plots the average value of the obtained data. The graph of FIG. 5 shows a typical example selected from the data obtained from 20 samples.

From FIG. 7, in the case of paper having a density of 0.5 to 1.0 g / cm ³ , that is, 50NFB, HS, AT, HS120, and S80, as the paper thickness increases, the breaking strength [N] / movement distance [ The value of [mm] increases, and it becomes easier to transmit the force to the fragrance capsule at a small pushing distance. However, when the paper thickness is about 250 μm, the breaking strength [N] / movement distance [mm] reaches a peak. On the other hand, a resistance paper having a thickness of 430 μm but a density of 0.27 g / cm ³ has a small value of breaking strength [N] / movement distance [mm] and is difficult to transmit force to the perfume capsule.

From the above results, when paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 μm or more is used, the load necessary for crushing the perfume capsule with a smaller indentation distance It can be seen that. Actually, when paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 μm or more is used, the pressure applied to the finger is small and the perfume capsule 23 is crushed with a small force. I felt that it was easy to do. On the other hand, when a paper having a density of less than 0.5 g / cm ³ or a paper having a thickness of less than 100 μm is used, a large indentation distance is required to give a load necessary for crushing the fragrance capsule. I understand that. Actually, when using a paper having a density of less than 0.5 g / cm ³ or a paper having a thickness of less than 100 μm, the pressure applied to the finger is large and the paper is easily deformed or broken. A feeling that the fragrance capsule 23 was difficult to be crushed was obtained.

Note that the difference in the maximum arrival point of the load observed in FIG. 5 is due to the variation in the hardness of the fragrance capsule 23.

Example 2. Effect of paper thickness on pressure distribution when crushing a perfume capsule According to the same method as in Example 1, a perfume capsule 23 is placed on each test paper placed on elastic rubber, and the feel of the rheometer from above. The perfume capsule 23 was crushed by applying pressure with the pressure shaft. When the capsule collapsed, the pressure distribution applied to the test paper was measured. The pressure distribution was measured using the measurement system and Inastomer (Inaba Rubber Co., Ltd.) shown in FIG. As the test paper, 50NFB and S80 used in Example 1 were used.

The measurement results are shown in FIG.
FIG. 8 shows that the pressure is higher at the center of the pressure distribution, and the pressure is gradually reduced concentrically as the distance from the center is increased. In FIG. 8, the central portion (blacked portion) observed with the test paper 50NFB has the highest pressure, and then the pressure of the portion with the rough hatching is the highest, and then the fine hatching is applied. Part pressure is high.

The result of FIG. 8 shows that S80 has a larger pressurization area as a whole and a lower pressure at the center than 50 NFB. This is because the test paper S80 having a predetermined density and thickness is less likely to concentrate on the finger when the fragrance capsule is crushed, and can be dispersed on a wider contact surface. Indicates that the burden on the finger is small. FIG. 9 schematically shows this state, that is, the state when the same load is applied to the test paper. FIG. 9 shows that the test paper 50NFB not having a predetermined thickness is more likely to concentrate the pressure on the finger locally, is higher at the center, and the test paper S80 has a wider pressure on the finger. It is easy to disperse and shows low in the center.

[First Embodiment]
The inventors have predicted that when papers of various thicknesses are wound around the filter plug 17 as shown in the reference example, the roundness of the filter 15 varies depending on the thickness of the paper. For this reason, the inventors examined the roundness of the cigarette 11.

FIG. 10 shows the result of comparing the roundness of the cigarette 11 when 50NFB and S2000 are used. The roundness (mm) is calculated by measuring the major axis and minor axis in the vicinity of the filter 15 of the cigarette 11 and calculating “roundness = major axis−minor axis (Equation 1)”. In a perfect circle, the major axis and the minor axis are equal, and the value of roundness is zero. As the shape becomes elliptical, the difference between the major axis and the minor axis increases, and the roundness value also increases. A QTM measuring instrument manufactured by British company Cerulean was used to measure the long and short diameters.

In FIG. 10, N indicates the number of samples (the number of cigarettes examined as a sample), and Ave indicates the average value of roundness. SD represents a standard deviation, Min represents a minimum value (mm), and Max represents a maximum value (mm). The single winding shows the cigarette 11 in which one layer of 50 NFB or S2000 is provided around the filter plug 17. The double winding shows the cigarette 11 in which two layers of 50 NFB are provided around the filter plug 17.

The test of the difference of the mean value (test of the difference of the population mean of the two groups) between the single winding of 50NFB shown in FIG. 10, the double winding of 50NFB, and the single winding of S2000 is performed. went. As a result, there was no significant difference in the roundness average value between the single winding of 50NFB and the double winding of 50NFB. On the other hand, between the single winding of 50NFB and the double winding of 50NFB, and the single winding of S2000, there was a significant difference in the average value of roundness at a significance level of 1%. From this test result, it can be said that the single winding of 50NFB and the double winding of 50NFB have better roundness than the single winding of S2000.

The first filter wrapping paper 21A is made of, for example, the above-described 50NFB. The second filter wrapping paper 21B has a density of 0.5 to 1.0 g / cm ³ and a thickness of 50 to 125 μm. The second filter wrapping paper 21B is composed of, for example, the above-described 50 NFB. The first filter wrapping paper 21A and the second filter wrapping paper 21B are examples of sheet-like members.

The cigarette 11 of the third aspect and the fourth aspect has substantially the same cross-sectional shape. FIG. 14 is a sectional view taken along line F14-F14 in FIGS. The following is a description of the two aspects described above unless otherwise specified.

The two filter plugs 17 are made of acetate tow filter medium, but may have the same properties or different properties. In the case where the properties of the two filter plugs 17 are different, for example, one filter plug 17 is constituted by a normal acetate tow filter medium, and the other filter plug 17 is constituted by an acetate tow filter medium containing activated carbon. Can do.

As shown in FIG. 14, the total thickness A of the first filter wrapping paper 21A and the second filter wrapping paper 21B forming a plurality of layers (two layers) is 100 to 250 μm.

As shown in FIG. 14, the filter plug 17 and the first filter wrapping paper 21 A are fixed by glue (first glue 31), for example, at one place in the circumferential direction of the filter plug 17. Similarly, the first filter wrapping paper 21A and the second filter wrapping paper 21B are fixed at one place in the circumferential direction of the filter plug 17, for example, with glue (second glue 32). The second filter wrapping paper 21B and the chip paper 16 are fixed at one place in the circumferential direction of the filter plug 17, for example, with glue (third glue 33). Each of the first glue 31 to the third glue 33 is linearly provided so as to cover the entire length of the filter 15 in the longitudinal direction of the cigarette 11, for example.
Subsequently, the split comfort was evaluated in the cigarette 11 of the first embodiment (third aspect). Evaluation was performed by having a total of 12 evaluators, 6 men and 6 women, divide the fragrance capsule 23 inside the cigarette 11 and indicate the ease of splitting (difficulty) with a score. . In this evaluation, the evaluator performed an operation of dividing the perfume capsule 23 on the sample of the example corresponding to the third aspect of the first embodiment and the sample of the comparative example, and evaluated each by the score. As shown in FIG. 15, a score of 1 to 7 points was assigned to each evaluation result from “Very difficult” to “Very easy”. In the cigarette of the comparative example, the second filter wrapping paper 21B is, for example, 50NFB, and the first filter wrapping paper 21A is, for example, LPWSOLL. LPWSOL is a common filter wrapping paper and is thinner than 50NFB.

Fig. 16 shows the evaluation results (question results). The average score of the split comfort of the cigarette of the comparative example was 3.08, and the standard deviation was 1.83. The average score of the split comfort score of the cigarette 11 of the example was 4.25, and the standard deviation was 1.42.

Subsequently, a test (t-test) of the difference between the population means of the two groups was performed on the average points of the comparative example and the example. In this case, since the same evaluator evaluates the split comfort for the comparative example and the example, it becomes a test in the case of “corresponding”. In this case, the null hypothesis is “there is no difference in the split comfort of the fragrance capsules of the comparative example and the example”. Further, the alternative hypothesis is that when the average point m ₁ of the comparative example is smaller than the average point m ₂ of the example, the example is more comfortable for the fragrance capsule than the comparative example. The P value refers to the probability for the statistic t in the standard normal distribution. Incidentally, t-test in this case is a alternative hypothesis "m _{1 <m} _2", and one-sided.

In the test result of the t test, the one-sided P value was 0.04184, which is smaller than the significance level of 5%. For this reason, there is a significant difference between the splitting comfort of the example and the comparative example, and an alternative hypothesis that “the splitting comfort of the fragrance capsule is better than that of the comparative example” can be adopted. In addition, in the cigarette 11 of the 4th aspect of 1st Embodiment, the fragrance | flavor capsule 23 is arrange | positioned in the hollow part 24. FIG. For this reason, in the fourth aspect, the repelling force of the filter plug 17 does not act on the hand when a load is applied to the fragrance capsule 23, and the fragrance is more than the cigarette 11 of the third aspect embedded in the filter plug 17. It is unlikely that the splitting comfort of the capsule 23 will decrease. For this reason, in the cigarette 11 of a 4th aspect, it is estimated similarly that the split comfort of the fragrance | flavor capsule 23 becomes favorable rather than a comparative example.

According to the first embodiment, the cigarette 11 forms a tobacco filler 12 and a tobacco rod 14 including a wrapping paper 13 wound around the tobacco filler 12, a filter plug 17 including a filter medium, and a plurality of layers.
