[Reference type]

The following describes the reference type for cigarettes. In the reference type, the fragrance capsule may be directly embedded in the filter material constituting the filter (the first aspect), or may be disposed in the hollow portion (the second aspect) formed between the plurality of filters.

As shown in Fig. 1, the cigarette 11 of the first aspect of the reference type includes a tobacco rod 14 having a tobacco filler 12 (filament tobacco, tobacco) and a periphery of the tobacco filler 12 a roll paper 13; a filter 15 disposed adjacent to the tobacco rod 14; and an outer paper 16 that is threaded around the tobacco rod 14 and the filter by spanning the tobacco rod 14 and the filter 15 On the mouth 15.

The filter 15 has a single filter plug 17, a filter wrapper 21 wound around the filter plug 17, embedded in the filter 15 (within the filter plug 17), and The capsule 23 containing the content liquid of the fragrance is held in the film 22. In the first aspect, the paper of at least one of the filter wrapper 21 and the outer wrapper 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 of the second aspect of the reference type includes a tobacco rod 14 having a tobacco filler 12 and a roll paper 13 wound around the tobacco filler 12; a filter 15 And the outer paper 16 is wound around the tobacco rod 14 and the filter 15 in such a manner as to span the tobacco rod 14 and the filter 15 and connect them.

The filter 15 includes two filter plugs 17 which are separated from each other and disposed via the hollow portion 24, and are wound around the two filter plugs 17 to form a hollow portion 24 between the filter plugs 17. The filter wrapper 21 around the two filter plugs 17 and the capsule 23 located in the hollow portion 24 and holding the content liquid containing the fragrance in the film 22 are provided.

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

In the following, unless otherwise stated, the description of the above two aspects is given.

The density and thickness of the paper having a density of 0.5 to 1.0 g/cm ³ and a thickness of 100 to 250 μm are larger than that of the filter wrapper 21 or the paper generally used for the outer wrapper 16 by such density The thickness has a higher capsule rupture performance.

In the present specification, the density of the paper means that the basis weight and thickness of the paper for the raw material of the cigarette are measured according to the methods specified in JIS P 8124 and JIS P 8188, respectively, and the obtained value is brought into the following formula. The value obtained. That is, "density (g/cm ³ ) = basis weight (g/m ² ) / thickness (mm) × 1000... formula (2)".

Further, 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 wrapper 21, the outer layer 16 can be used having a density of 0.5 to 1.0 g/cm ³ and 100 to 250 μm. For paper having a thickness, paper having a general density and thickness which is generally used for the outer paper 16 can also be used. Similarly, 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 outer layer paper 16, the filter wrapper 21 can be used having a density of 0.5 to 1.0 g/cm ³ and 100 to 250 μm. For the paper of the thickness, paper having a general density and thickness used in the general filter wrapper 21 can also be used.

In the present reference form, the paper of at least one of the filter wrapper 21 and the outer wrapper 16 has a density of 0.5 to 1.0 g/cm ³ and a thickness of 100 to 250 μm, preferably 0.7 to 1.0 g/cm ³ . The density and the thickness of 180 to 250 μm, more preferably have a density of 0.8 to 1.0 g/cm ³ and a thickness of 240 to 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 , when the fragrance capsule 23 is broken, the paper is easily deformed and bent, and the pressure applied to the finger is concentrated locally, so that the fragrance capsule is made. 23 is difficult to break. Further, if the density is more than 1.0 g/cm ³ , the manufacturing cost of the paper becomes high and is not preferable. In order to prevent the leakage of the capsule content liquid, the density of the paper is preferably large and is in the range of 0.5 to 1.0 g/cm ³ .

Even if the density of the paper is in the range of 0.5 to 1.0 g/cm ³ , if the thickness is less than 100 μm, when the fragrance capsule 23 is broken, the paper is easily deformed and bent, and the pressure applied to the finger is concentrated locally, so that the fragrance capsule is made. 23 is difficult to break. Further, if the thickness is more than 250 μm, it is difficult to perform the winding step of manufacturing a cigarette, and it becomes difficult to obtain the feeling that the fragrance capsule 23 is broken.

In the first aspect, the filter wrapper 21 is also referred to as a take-up paper, and similarly, when the take-up paper is a paper having a density of 0.5 to 1.0 g/cm ³ and a thickness of 100 to 250 μm, the basis weight may be 50 to 250 g. /m ² , air permeability can be 0 to 30000 CU. In the first aspect, in order to prevent the liquid in the fragrance capsule 23 from oozing out to the outside of the cigarette 11, the degree of air permeability of the filter package 21 can be made zero.

The filter wrapper 21 in the second aspect is also referred to as a forming paper. 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 wrapper 21, the basis weight may be 50 to 250 g/m ² and the air permeability may be 0 to 30,000 CU. In the second aspect, since the fragrance capsule 23 is located in the hollow portion 24 of the filter 15, the purpose of preventing the liquid in the fragrance capsule 23 from oozing out to the outside of the cigarette 11 is particularly preferable, so that the air permeability of the filter package to 21 is 0. . 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 wrapper 21, the outer paper 16 can use paper having a general density and thickness which is generally used as the outer layer paper 16. At this time, the basis weight of the outer layer paper 16 may be, for example, 20 to 60 g/m ² , and the thickness thereof may be, for example, 20 to 60 μm.

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

The fragrance capsule 23 is composed of a film 22 and a content liquid 25 containing a fragrance. The film 22 may be, for example, starch, dextrin, polysaccharide, cold weather, yam, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride or the like, and may further contain a perfume or a coloring agent. The fragrance capsule 23 is preferably colored even when it is wrapped by the filter wrapper 21 or the outer layer paper 16 and is formed by the smoker when the perfume capsule 23 is crushed. It is preferable that the film 22 contains a coloring material such as blue No. 1 or the like.

As the fragrance of the content liquid 25, any fragrance used for smoking articles such as menthol or plant essential oil can be used. The main spices include menthol, tobacco extract, and natural botanical flavors (eg, cinnamon, sage, herbs, chamomile, geranium, sweet tea, clove, lavender, Cardamon, diced, nutmeg, bergamot, geranium, honey extract, rose oil, lemon, orange, cinnamon, caraway, jasmine, ginger, medlar (coriander), vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, Ylang-ylang, fennel, anise, liquorice, St. John's Plant), plum extract, peach extract, etc., sugars (eg glucose, fructose, high fructose syrup, caramel, etc.), cocoa (powder, extracts, etc.), esters (eg isoamyl acetate) , linalyl acetate, isoamyl propionate, linalyl butyrate, etc., ketones (eg menthone, ionone, damascenone, b malt Alcohol (ethyl maltol, etc.), alcohols (such as geraniol, linalool, anethole, eugenol, etc.), aldehydes (such as vanillin, benzene) Formaldehyde (benzaldehyde, anisaldehyde, etc.), lactones (such as γ-undecalactone, γ-decalactone, etc.), animal flavors (such as musk, Ambergris, civet, castoreum, etc., olefins (e.g., limonene, pinene, etc.). These perfumes may be used singly or in combination.

As the solvent of the content liquid 25, a solvent suitable for the fragrance can be used, and a medium chain fatty acid triglyceride (MCT) (specifically, trioctanoic acid/capric glyceride), propylene glycol, water, ethanol, or the like can be used. The content liquid 25 may further contain other additives such as other solvents, pigments, emulsifiers, and tackifiers.

The method for producing the fragrance capsule 23 is not particularly limited. However, for example, if the dropping method is used, the fragrance capsule 23 having the seamless film 22 can be produced. In this method, a double-layer nozzle is used, and the content liquid is discharged from the inner nozzle, and at the same time, the liquid film material is discharged from the outer nozzle, whereby the film liquid can be wrapped around the content liquid without seams.

The fragrance capsule 23 may, for example, have the shape of a sphere or a cylinder, and the sphere includes both a sphere having a slightly circular cross section and an elliptical body having an elliptical cross section. The fragrance capsule 23 is preferably in the shape of a sphere having a slightly rounded cross section. When the fragrance capsule 23 has a slightly rounded sphere, the diameter may be, for example, 1.0 to 8.0 mm, and when it is elliptical, for example, it may be a maximum diameter of 1.0 to 7.0 mm and a minimum diameter of 1.0 to 7.0 mm, which is 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. As is clear from the example 3 described later, if the size of the fragrance capsule 23 is too small, the pressing distance of the fragrance capsule 23 is long when it is broken. Therefore, in the case of a sphere, the diameter is preferably 3.0 mm or more, and in the case of an ellipse, it is preferably the smallest. The diameter of 3.0 mm or more is preferably 3.0 mm or more in the case of a cylindrical body.

Further, the fragrance capsule 23 is preferably a breaker which itself can be used with an intensity of 10 to 35 [N]. If a paper having a density of 0.5 to 1.0 g/cm ³ and a thickness of 100 to 250 μm is used, a harder capsule may be, for example, a capsule which is capable of being destroyed by a strength of more than about 25 [N] and less than about 30 [N]. It can also be broken with a small force and a short press-in distance. The harder capsule has the advantage that the capsule-filled cigarette 11 is not easily broken when exposed to high temperatures or when handled.

As evidenced by the reference examples described later, a local acupressure is felt when a capsule which can be broken by an intensity of about 30 [N] is directly crushed by a finger or ruptured on a forming paper (50NFB). However, when rupturing on paper having a density of 0.5 to 1.0 g/cm ³ and a thickness of 100 to 250 μm, local finger pressure is not felt, and the fragrance capsule can be easily broken.

In the first aspect and the second aspect of the reference pattern, the filter plug 17 can be composed of a filter material of an acetate bundle, similarly to a cigarette generally having a filter. The filter plug 17 may be composed only of a filter material, or may be composed of a filter material and a plug winding paper that is wound around the periphery thereof. When the filter 15 contains the enthalpy-filled filter plug 17, the filter plug 17 on the tobacco yarn side and the filter plug 17 on the suction side may have the same material and construction, and may have different materials and configurations.

The acetate bundle may be, for example, a single filament fineness of 1.9 to 12.0 (g/9000 m), a total fineness of 10,000 to 44,000 (g/9000 m), a fiber bundle of 830 to 23500 (bar), and a pass. The gas impedance is 100 to 600 (mmH2O/120mm). A plasticizer such as triacetin may be added to the acetate bundle, and the plasticizer may be added in an amount of 6 to 10% by weight based on the weight of the acetate bundle. When the activated carbon is added to the acetate bundle, the plasticizer may be added in an amount of 2 to 20% by weight based on the weight of the acetate bundle.

When the filter material is too hard, when the filter containing the fragrance capsule is crushed by the finger, the rebound force caused by the filter plug 17 becomes larger, and the single yarn fineness is 3.0 (g/9000 m) or more, and more preferably The total fineness is 35,000 (g/9000 m) or less.

The filter 15 has, for example, a circumference of about 14 to 26 mm and a length which is the same as a general filter, for example, 17 to 31 mm. In the filter 15 of the first aspect, 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 each filter plug 17 may have a length of 5 to 20 mm.

In the cigarette 11 of the second aspect shown in Fig. 2, two filter plugs 17 are disposed via one hollow portion 24, but n (n is an integer of 2 or more) filter plugs 17 may be used. It is disposed via (n-1) hollow portions 24, for example, n is 2 to 4, preferably n is 2 to 3, and more preferably n is 2.

In the present aspect, the tobacco rod 14 is identical to the general cigarette 11, for example, consisting of a tobacco filler 12 and a tobacco roll 13 wrapped around it, for example, having a circumference of about 14 to 26 mm and 53 to Length of 67mm.

Example Reference embodiment

Example 1: Effect of the thickness and density of paper on the press-in distance when the capsule is crushed

In this example, the following 6 types of test papers were used (the source of each test paper in brackets). The characteristics of each test paper are shown in Table 1 below. Experiments in the experiment The paper system uses a size of 2 cm square.

(1) 50NFB (Japan Paper Papylia Co., Ltd.)

(2) HS (Xinbachuan Paper Co., Ltd.)

(3) AT (Xinbachuan Paper Co., Ltd.)

(4) HS120 (Xinbachuan Paper Co., Ltd.)

(5) S80 (Japan Paper Papylia Co., Ltd.)

(6) Resistive paper (Japan Paper Papylia Co., Ltd.)

In Fig. 3, the "destructive strength" indicates the load [N] applied to the fragrance capsule when the fragrance capsule is broken, and the "moving distance" indicates the penetration distance [mm] when the fragrance capsule is broken. In addition, the basis weight of 50NFB was 50.0 g/m ² .

The fragrance capsule 23 was prepared by mixing a film material (15% by weight) with a content liquid 25 (85% by weight) and dropping it by a dropping method. The main components of the coating material and the content liquid constituting the fragrance capsule 23 are as follows.

(i) Membrane material

Gelatin, orchid, starch, glycerin and sorbitol.

(ii) content liquid

Medium chain fatty acid triglyceride (trioctanoic acid/capric glyceride) (83% by weight).

The prepared fragrance capsule 23 is a sphere having a diameter of about 4.5 mm. Further, the hardness of the fragrance capsule 23 is about 30N. Further, in the present embodiment, the content liquid 23 of the fragrance capsule 23 may be composed only of a solvent, and although it does not contain a fragrance, it has been confirmed that the presence or absence of the fragrance does not affect the rupturability of the capsule.

Using the measuring system 26 shown in Fig. 4, the relationship between the pressing distance and the load at the time of breaking of the fragrance capsule 23 was examined. That is, the perfume capsule is placed on the experimental paper placed on the elastic rubber, and the pressure is applied from above by the pressure sensing shaft of the rheometer. The capsule is broken. The press-in distance (mm) (also referred to as the moving distance) and the load (N) at this time were measured. The measurement was carried out using Sun RHEO METER CR3000EX (SUN SCIENTIFIC Co., Ltd.).

The measurement results are shown in Fig. 5. In Fig. 5, (1) shows 50NFB, (2) shows HS, (3) shows AT, (4) shows HS120, (5) shows S80, and (6) shows resistive paper.

As can be seen from Fig. 5, the pressing distance (moving distance) required for HS, AT, HS120, and S80 to reach the same load is smaller than that of the test paper 50NFB. On the other hand, the resisting paper requires a larger press-in distance (moving distance) to reach the same load than 50NFB. The case where 50NFB, resistive paper, and S80 are applied with the same load is schematically shown in Fig. 6. Fig. 6 shows that if paper having a specific density and thickness, such as S80 or the like, is used, the same load can be imparted to the fragrance capsule 23 with a smaller press-in distance, and the paper is not easily bent when a load is applied, so the fragrance can be applied. The pressure at which the capsule 23 breaks is dispersed to a wider contact surface. On the other hand, in Fig. 6, it is shown that if a paper having a small density (resistive paper) or a paper having a small thickness (50NFB) is used, the pressing distance required to impart a specific load is large, and the paper is easily bent when a load is applied. When folded, the pressure at which the fragrance capsule 23 is broken is easily concentrated at one point.

Based on this result, the relationship between the thickness of the paper and the ease with which the force is transmitted to the fragrance capsule 23 is shown in Fig. 7. In Fig. 7, the horizontal axis represents the thickness [μm] of the paper, and the vertical axis represents the breaking strength [N] / moving distance [mm]. Here, [breaking strength] indicates the load [N] applied to the fragrance capsule 23 when the fragrance capsule 23 is broken, and [moving distance] indicates the pressing distance [mm] when the fragrance capsule 23 is broken. The large breaking strength [N]/moving distance [mm] indicates that the fragrance capsule 23 can be given a large load with a small pressing distance, that is, it is easy to transmit the force to the fragrance capsule 23 with a small pressing distance. Figure 7 (1) indicates 50NFB, (2) indicates HS, (3) indicates AT, (4) indicates HS120, (5) indicates S80, and (6) indicates resistive paper. Further, in the graph of Fig. 7, 20 samples were prepared for each test paper, and the press-in distance (mm) and the load (N) were measured, and the average value of the obtained data was plotted. The graph of Fig. 5 above is selected from the data obtained from 20 samples, and one of the more typical examples is selected.

As can be seen from Fig. 7, when paper having a density of 0.5 to 1.0 g/cm ³ , that is, 50NFB, HS, AT, HS120, and S80, the breaking strength [N] / moving distance [mm] increases as the thickness of the paper increases. The value of ] is increased, and it is easy to transfer the force to the perfume capsule with a small press-in distance. However, if the thickness of the paper is about 250 μm, the breaking strength [N] / moving distance [mm] will reach the upper limit. On the other hand, a resistive paper having a thickness of 430 μm but having a density of 0.27 g/cm ³ has a small value of the breaking strength [N] / moving distance [mm], and it is difficult to transfer the force to the flavor capsule.

From the above results, it is understood that if a paper having a density of 0.5 to 1.0 cm ³ and a thickness of 100 μm or more is used, the load required for crushing the fragrance capsule can be imparted with a smaller press-in distance. In fact, when paper having a density of 0.5 to 1.0 cm ³ and having a thickness of 100 μm or more is used, in addition to the pressure applied to the finger, a feeling that the fragrance capsule 23 is easily broken with a small force can be obtained. On the other hand, it is understood that if paper having a density of less than 0.5 cm ³ or paper having a thickness of less than 100 μm is used, a large press-in distance is required in order to impart a load required to break the fragrance capsule. In fact, if paper having a density of less than 0.5 cm ³ or paper having a thickness of less than 100 μm is used, the paper may be deformed or easily bent except for the pressure applied to the finger, and it is difficult to make The feeling of the fragrance capsule 23 rupture.

In addition, the difference in the maximum arrival point of the load observed in Fig. 5, It is caused by the inconsistent hardness of the fragrance capsule 23.

Example 2: Results of the thickness of the paper relative to the pressure distribution when the perfume capsule is broken

According to the same method as in Example 1, the fragrance capsule 23 was placed on each of the test papers placed on the elastic rubber, and pressure was applied from above to the sensation axis of the rheometer to rupture the fragrance capsule 23. The pressure distribution applied to the test paper at the point of time when the capsule collapsed was measured. The measurement of the pressure distribution was carried out using the measurement system shown in Fig. 4 and Inastmer (Inaba-rubber Co., Ltd.). The test paper used was 50NFB and S80 used in Example 1.

The measurement results are shown in Fig. 8.

Fig. 8 shows that the pressure is higher in the center portion of the pressure distribution, and the pressure is concentrically lowered as it goes away from the center portion. In Fig. 8, the pressure at the center portion (blackened portion) observed in the test paper 50NFB is the highest, the pressure in the thick oblique line portion is the second highest, and the pressure in the thinned portion of the thin line is the second highest.

The results in Fig. 8 show that the S80 has a larger overall pressing area and a lower central portion pressure than the 50NFB. This indicates that the test paper S80 having a specific density and thickness, when the fragrance capsule is broken, is difficult to concentrate on the pressure applied to the finger, and can be dispersed over a wider contact surface, and the load applied to the finger is small. In this state, that is, the case where the same load is applied to the test paper is schematically shown in Fig. 9. Fig. 9 shows a test paper 50NFB which does not have a specific thickness, the pressure applied to the finger is easily concentrated locally, and the center portion is high, and the pressure applied to the finger of the test paper S80 is easily dispersed on the wider contact surface, and the center portion low.

[First embodiment]

The inventors and the like believe that various thicknesses are used in the manner shown in the reference embodiment. When the degree of paper is wrapped around the filter plug 17, the difference in roundness of the filter 15 is caused by the thickness of the paper. Therefore, the inventors conducted research on the roundness of the cigarette 11.

Fig. 10 shows the results of comparing the roundness of the cigarette 11 when 50NFB and S2000 were used. The roundness (mm) is a long diameter and a short diameter in the vicinity of the filter 15 of the cigarette 11, and is calculated by "roundness = long diameter - short diameter (formula 1)". The true true circle has the same length and minor diameter, and the true roundness has a value of zero. As the ellipse becomes elliptical, the difference between the long diameter and the short diameter becomes larger, and the value of the true roundness also becomes larger. The long and short diameters were measured using a QTM tester manufactured by Cerulean, UK.

In Fig. 10, N indicates the number of samples (the number of cigarettes studied as a sample), and Ave indicates the average of the roundness. SD indicates the standard deviation, Min indicates the minimum value (mm), and Max indicates the maximum value (mm). The single layer splicing means a cigarette 11 in which a layer of 50NFB or S2000 is disposed around the filter plug 17.

The first filter wrapper 21A and the second filter wrapper 21B are examples of a sheet-like member.

The third aspect has the same cross-sectional shape as the cigarette 11 of the fourth aspect. Fig. 14 is a cross-sectional view taken along line F14-F14 of Figs. 12 and 13. In the following, the above two aspects are described without special mention.

The two filter plugs 17 may be constructed of a filter material of an acetate bundle, but may have the same properties as each other or may have different properties from each other. When the properties of the two filter plugs 17 are different, for example, the filter plug of one of the acetate bundles may be used to constitute one of the filter plugs 17, and the filter material of the acetate bundle to which the activated carbon is added may constitute the other. Filter plug 17.

As shown in Fig. 14, the total thickness A of the first filter wrapper 21A and the second filter wrapper 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 wrapper 21A One of the circumferential directions of the filter plug 17 is fixed by, for example, a paste (first paste 31). Similarly, the first filter wrapper 21A and the second filter wrapper 21B are fixed in one of the circumferential directions of the filter plug 17, for example, by a paste (second paste 32). The second filter wrapper 21B and the outer layer paper 16 are fixed in one of the circumferential directions of the filter plug 17, for example, by a paste (third paste 33). Each of the first paste 31 to the third paste 33 is linearly disposed, for example, in the longitudinal direction of the cigarette 11 so as to cover the entire length of the filter 15 .

Next, the rupture feeling of the cigarette 11 of the first embodiment (the third aspect) was evaluated. The evaluation was carried out in such a manner that an evaluator of 6 males and 6 females and 12 totals crushed the fragrance capsule 23 located inside the cigarette 11, and the ease of rupture (difficulty of rupture) was expressed by a score. In this evaluation, the evaluator performed the rupture operation of the fragrance capsule 23 on the samples of the examples and the comparative examples corresponding to the third aspect of the first embodiment, and evaluated the scores separately. As shown in Figure 15, the results of each assessment are divided into 1 to 7 points with "very difficult to break" to "very easy to break". In the cigarette of the comparative example, the second filter wrapper 21B is, for example, 50NFB, and the first filter wrapper 21A is, for example, LPWSOLL. LPWSOLL is generally used as a filter wrapper and is thinner than 50NFB.

Figure 16 shows the results of the evaluation (inquiry results). The average score of the rupture sensation score of the cigarette of the comparative example was 3.08, and the standard deviation was 1.83. The average score of the rupture feeling score of the cigarette 11 of the example was 4.25, and the standard deviation was 1.42.

Next, regarding the average scores of the comparative examples and the examples, the detection of the difference between the average numbers of the two groups (t detection) was performed. At this time, the comparative examples and the examples were evaluated by the same evaluator for the rupture sensation, so that the test was "with control". At this time, the return to zero assumes that "the fragrance capsule of the comparative example and the example does not differ in the rupture feeling". Further, the comparison assumes that "the average score m ₁ of the comparative example < the average score m ₂ of the examples, the rupture feeling of the perfume capsule of the example is better than the comparative example". The P value is the probability of a statistic t relative to the normalized normal distribution. In addition, the t detection system at this time is assumed to be "m ₁ <m ₂ ", so it is one-sided detection.

In the test results of the t test, the one-sided P value is 0.04184 which is a significant level of less than 5%. Therefore, there is a significant difference in the rupture sensation between the examples and the comparative examples, and the comparative hypothesis that the rupture feeling of the perfume capsule of the example is better than the comparative example can be employed. Further, in the cigarette 11 of the fourth aspect of the first embodiment, the fragrance capsule 23 is disposed in the hollow portion 24. Therefore, in the fourth aspect, when a load is applied to the fragrance capsule 23, the rebound force of the filter plug 17 does not act on the hand, compared to the third aspect embedded in the filter plug 17. In the case of the cigarette 11, it is difficult to think that the rupture feeling of the fragrance capsule 23 is lowered. Therefore, it is presumed that the cigarette 11 of the fourth aspect is similar to the comparative example, and the rupture feeling of the fragrance capsule 23 is preferable.

According to the first embodiment, the cigarette 11 comprises: a tobacco rod 14 having a tobacco filler 12 and a roll paper 13 wound around the tobacco filler 12; and a filter 15 comprising: a filter material a filter plug 17, a plurality of sheet-like members wound around the filter plug 17 in a manner of forming a plurality of layers, a capsule located in the filter 15 and covering and holding the content liquid 25 with the film 22; and an outer layer paper , which is attached to the tobacco rod 14 and the filter 15 by connecting the tobacco rod 14 and the filter 15; and the sheet-like member has a density of 0.5 to 1.0 g/cm ³ and forms the plurality of layers The total thickness A of the plurality of sheet-like members is 100 to 250 μm.

Generally, the paper system as shown in the reference type (Reference Example) is not easily bent due to high rigidity (low flexibility), and the filter 15 (cigarette 11) is difficult to be wound into a true circle. According to the above configuration, the roundness of the cigarette 11 can be favorably maintained, and the feeling of the smoker when the capsule is broken can be improved. Further, according to the above configuration, each of the sheet-like members can be reduced The thickness is comparable to the above-described reference embodiment using one thicker filter wrapper 21, and it is possible to realize a cigarette having high applicability to an existing cigarette reeling machine or a filter manufacturing machine. As a result, in terms of manufacturing cost, it is possible to prevent the cost of the cigarette 11 of the present embodiment from being extremely high in comparison with the conventional cigarette.
