  Hereinafter, the present invention will be described, but the following description is intended to explain the present invention in detail and is not intended to limit the present invention.

  In the cigarette of the present invention, the perfume capsule may be disposed in a hollow portion formed between a plurality of filter plugs (first aspect), or may be directly embedded in a filter medium constituting the filter ( Second aspect).

The cigarette according to the first aspect of the present invention is as shown in FIG.
A tobacco rod (11) including a tobacco filler (11a) and a wrapping paper (11b) wound around the tobacco filler;
Two filter plugs (12a) spaced apart from each other through a hollow portion, filter wrapping paper (12b) wound around the filter plug so as to form a hollow portion between the filter plugs, A filter (12) including a fragrance capsule (12c) located in the hollow portion and holding a content liquid containing the fragrance in the film;
Including the tobacco rod and chip paper (13) wound on the filter so as to connect the tobacco rod and the filter;
At least one of the filter wrapping paper and the chip paper has a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm. In FIG. 1A, the filter plug (12a) is wound up by the plug web (12d), but the plug web (12d) may or may not exist. . FIG. 2 shows a state in which the cigarette according to the first aspect of the present invention is disassembled. In FIG. 2, two filter plugs (12a) are arranged apart from each other, and a filter wrapping paper (12b) and a chip paper (13) are wound around them, so that a hollow portion is formed between the filter plugs (12a). It shows that it is formed and the perfume capsule (12c) is located in such a hollow part.

The cigarette according to the second aspect of the present invention is as shown in FIG.
A tobacco rod (11) including a tobacco filler (11a) and a wrapping paper (11b) wound around the tobacco filler;
A single filter plug (12a), a filter wrapping paper (12b) wound around the filter plug, and a fragrance capsule (embedded in the filter and holding a liquid containing the fragrance in the film) 12c), and a filter (12)
Including the tobacco rod and chip paper (13) wound on the filter so as to connect the tobacco rod and the filter;
At least one of the filter wrapping paper and the chip paper has a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm.

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

In the present invention, if at least one of the filter wrapping paper and the chip paper has a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm, the perfume can be obtained depending on the properties of the paper. The ease of crushing the capsule can be improved.

Paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is larger in density and thickness than paper generally used for filter wrapping paper and chip paper. High capsule crushing performance due to thickness. Therefore, the characteristic paper used in the present invention, that is, paper having a density of 0.5 to 1.0 g / cm ³ and a thickness of 100 to 250 μm is also referred to as “the high performance paper of the present invention”.

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 determined by fitting: Formula: Density (g / cm ³ ) = Basis weight (g / m ² ) / Thickness (mm) × 1000. Moreover, in this specification, the thickness of paper refers to the value measured by the method prescribed | regulated to JISP8118.

  In the present invention, when the high performance paper of the present invention is used as the filter wrapping paper, the same high performance paper may be used as the chip paper, and it has a normal density and thickness generally used as chip paper. Paper may be used. Similarly, when the high-performance paper of the present invention is used as the chip paper, the filter wrapping paper may use the same high-performance paper, and has a normal density and thickness generally used as filter wrapping paper. Paper may be used.

In the present invention, at least one of filter wrapping paper and chip paper 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 density and 180-250 μm thickness, more preferably 0.8-1.0 g / cm ³ density and 240-250 μm thickness.

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 perfume capsule is crushed, and the pressure on the finger is locally applied. Concentration makes it difficult to break the perfume capsules. On the other hand, if the density is greater than 1.0 g / cm ³ , the paper production cost increases, which is not preferable. The density of the paper is desirably 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 smaller than 100 μm, the paper is easily deformed and broken when the fragrance capsule is crushed, and the pressure on the finger is reduced. Since it concentrates locally, it becomes difficult to crush the fragrance capsule. 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.

The filter wrapping paper (12b in FIG. 1 (a)) in the first embodiment is also called a molded paper, and when the high-performance paper of the present invention is adopted as the molded paper, the basis weight is generally 50 to 250 g / m ^2. The air permeability can be 0 to 30000 CU. In the first aspect, since the fragrance capsule is located in the hollow portion of the filter, it is particularly preferable to set the air permeability of the filter wrapping paper to 0 for the purpose of preventing the liquid in the fragrance capsule from exuding to the outside of the cigarette. . The filter wrapping paper (12b in FIG. 1 (b)) in the second aspect is also called a web, and similarly, when the high-performance paper of the present invention is used for the web, the basis weight is 50 to 250 g / m ² , The air permeability can be 0 to 30000 CU. Also in the second embodiment, the air permeability of the filter wrapping paper can be set to 0 for the same purpose as described above. When the high-performance paper of the present invention is adopted as a forming paper or a web, the chip paper can be a paper having a normal density and thickness generally used as a chip paper. For example, the basis weight is 20 to 60 g / m ^2, the thickness may be 20 to 60 [mu] m.

  In the aspect of the present invention, the fragrance capsule is accommodated in the hollow portion between the filter plugs or embedded in the filter plug as described above. One perfume capsule may be present in the filter, or a plurality of (for example, 2 to 10) perfume capsules may be present. When the fragrance capsule is accommodated in the hollow portion, one fragrance capsule may be accommodated per one hollow portion, or a plurality of (for example, 2 to 10) fragrance capsules may be accommodated. .

  The fragrance capsule is composed of a film and a content liquid containing the fragrance. For the film, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride, and the like can be used, and flavors and coloring agents can be further included. The fragrance capsule is preferably colored so that the smoker can recognize it when crushing the fragrance capsule even when surrounded by filter wrapping paper or chip paper having opacity, and the film is colored such as blue No. 1 Etc. are preferably included.

  As a fragrance | flavor of a content liquid, 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, etc.), lactones (eg, γ-undecalactone, γ-nonalactone, etc.), animal perfumes (eg, musk, ambergris, civet, castrium, etc.), hydrocarbons (eg, limonene, pinene, etc.) Can be mentioned. These fragrances may be used alone or in combination.

  As a solvent for the content liquid, 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. . The content liquid may further contain other additives such as other solvents, pigments, emulsifiers and thickeners.

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

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

  Moreover, the fragrance | flavor capsule itself is a thing which can be destroyed with the intensity | strength of about 10-35 [N]. When the high-performance paper of the present invention is used, relatively hard capsules such as capsules that can be broken at a strength higher than about 25 [N] and lower than about 30 [N] can be crushed with a small force and a short indentation distance. Is possible. Harder capsules have the advantage that the encapsulated cigarettes are less likely to break when exposed to high temperatures or when transported.

  As demonstrated in the examples described later, when a capsule that can be broken at a strength of about 30 [N] is crushed directly with a finger or is crushed from the top of an existing paper (50NFB), local acupressure is applied. Although it feels, when it crushes from on the high performance paper of this invention, it is possible to crush a fragrance | flavor capsule easily, without feeling local finger pressure.

  In the embodiment of the present invention, the filter plug can be composed of a filter medium of acetate tow, like a normal cigarette with a filter. The filter plug may be composed only of the filter medium, or may be composed of the filter medium and a plug web wound around the filter medium. When the filter includes a plurality of filter plugs, the cut-side filter plug and the suction-side filter plug may have the same material and structure, or may have different materials and structures.

  Acetate tow has, for example, a single yarn fineness of 1.9 to 8.6 (g / 9000m), a total fineness of 17000 to 44000 (g / 9000m), a number of fibers of 2400 to 23500 (pieces), 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.

  From Example 4 to be described later, if the filter medium is too hard, the repulsion force by the filter plug when the filter containing the fragrance capsule is crushed with a finger is increased, and therefore the single yarn fineness is 3.0 (g / 9000 m) or more. More preferably, the total fineness is more preferably 35000 (g / 9000 m) or less.

  The filter may have a circumference of, for example, about 14 to 26 mm, and the length may be, for example, 17 to 31 mm, similar to a normal filter. In the filter according to the first aspect, the length of the hollow portion may be equal to or larger than the size of the fragrance capsule, for example, 3 to 7 mm, and the length of each filter plug may be 5 to 20 mm.

  In the cigarette of FIG. 1 (a), two filter plugs are arranged through one hollow portion, but n (n is an integer of 2 or more) filter plugs are (n-1) hollow portions. 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 invention, the cigarette rod is made of a cigarette filler and cigarette wrapping paper around the cigarette filler, like a normal cigarette, and has, for example, a circumference of about 14 to 26 mm and a length of 53 to 67 mm. Can do.

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.)

  The test paper 50NFB is a molded paper currently used in flavored capsule-containing cigarettes. In Table 1, “breaking strength” represents the load [N] applied to the fragrance capsule when the fragrance capsule was broken, and “movement distance” represents the indentation distance [mm] when the fragrance capsule was broken. Represents.

The fragrance capsule was prepared by mixing the film substance (15% by weight) and the content liquid (85% by weight) and dropping it. The main components of the coating substance and the content liquid constituting the fragrance capsule 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 perfume capsule was a sphere having a diameter of about 4.5 mm. Moreover, the hardness of the fragrance | flavor capsule was about 30N. In addition, in the present Example, although the content liquid of a fragrance | flavor capsule is comprised only from a solvent and does not contain a fragrance | flavor, it is demonstrated that the presence or absence of a fragrance | flavor does not affect the ease of crushing of a capsule.

  Using the measurement system shown in FIG. 3A, the relationship between the indentation distance and the load when the fragrance capsule 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 Sun RHEO METER CR3000EX (Sun Science Co., Ltd.).

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

  From the result of FIG. 3B, it can be seen that HS, AT, HS120, and S80 have a smaller pushing distance (movement distance) required to reach the same load than the 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. 3C schematically shows this state, that is, the state when the same load is applied to 50 NFB, resistance paper, and S80. FIG. 3C 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 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 a fragrance | flavor capsule can be disperse | distributed to a wider contact surface. On the other hand, FIG. 3C shows that when a low density paper (resistive paper) or a small thickness paper (50NFB) is used, the pressing 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 a fragrance | flavor capsule tends to concentrate on one point.

  Based on these results, FIG. 3D shows the relationship between the thickness of the paper and the ease of transmission of force to the fragrance capsule. In FIG. 3D, the horizontal axis indicates the paper thickness [μm], and the vertical axis indicates the breaking strength [N] / movement distance [mm]. Here, “breaking strength” means a load [N] applied to the fragrance capsule when the fragrance capsule is broken, and “movement distance” is an indentation distance [mm] when the fragrance capsule is broken. means. A large breaking strength [N] / moving distance [mm] means that a large load can be applied to the perfume capsule with a small indentation distance, that is, a force can be easily transmitted to the perfume capsule with a small indentation distance. In FIG. 3D, (1) represents 50NFB, (2) represents HS, (3) represents AT, (4) represents HS120, (5) represents S80, and (6) represents resistance paper. In addition, the graph of FIG. 3D 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. 3B shows a typical example selected from the data obtained from 20 samples.

As shown in FIG. 3D, 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 a 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 is crushed with a small force. I felt that it was easy. 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 perfume capsule. I understand that. Actually, 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, the pressure applied to the finger is large and the paper is easily deformed or broken. A feeling that the perfume capsules are difficult to break was obtained.

  In this example, the perfume capsules prepared in the same way were applied to each test paper, so the maximum point of load (the load required to crush the perfume capsules) should be the same for all test papers. It is. Therefore, the difference in the maximum load point observed in FIG. 3B is considered to be due to a slight difference in the hardness of the fragrance capsule.

Example 2. Effect of paper thickness on pressure distribution when crushing perfume capsules According to the same method as in Example 1, a perfume capsule is placed on each test paper placed on elastic rubber, and the pressure sensitivity of the rheometer from above The perfume capsules were crushed under pressure by the 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. 3A. As the test paper, 50NFB and S80 used in Example 1 were used.

  The measurement results are shown in FIG. 4A.

  FIG. 4A shows that the pressure is higher in the central part of the pressure distribution, and gradually decreases concentrically as the distance from the central part increases. In FIG. 4A, the central portion (blacked portion) observed with the test paper 50NFB has the highest pressure, and then the pressure in the portion with the rough hatching is high, and then the fine hatching is applied. Part pressure is high.

  The result of FIG. 4A shows that S80 has a larger pressurization area as a whole and a lower pressure in the central portion 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. 4B schematically shows this state, that is, the state when the same load is applied to the test paper. FIG. 4B shows that the test paper 50NFB not having the 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.

  In Examples 1 and 2, the experiment was conducted by placing the perfume capsules directly on the test paper. For this reason, it is considered that the experimental results of Examples 1 and 2 directly reflect the first aspect of the present invention (the aspect in which the fragrance capsule is accommodated in the hollow portion between the filter plugs). Further, the fragrance capsule is sufficiently harder than the filter medium constituting the filter plug. In the second aspect of the present invention (an aspect in which the fragrance capsule is embedded in the filter medium in the filter plug), Since the hardness is directly felt with a finger, the experimental results of Examples 1 and 2 are considered to reflect the second aspect of the present invention (the aspect in which the perfume capsule is embedded in the filter medium in the filter plug).

Example 3 A filter in which a perfume capsule is arranged in a hollow part between filter plugs A perfume capsule was prepared in the same manner as in Example 1, and a filter in which a perfume capsule was arranged in a hollow part between filter plugs was prepared. The size of the filter was as shown in FIG. 5A. The filter plugs on the suction side and the cut side were as follows.

Suction side filter plug (acetate filter wound up with web)
Single yarn fineness 2.8 (g / 9000m)
Total fineness 35000 (g / 9000m)
Number of fibers 12500 (pieces)
Ventilation resistance 360 (mmH2O / 120mm)

Engraved side filter plug (NWA: non-wrap acetate filter)
Single yarn fineness 2.5 (g / 9000m)
Total fineness 31000 (g / 9000m)
Number of fibers 12400 (pieces)
Ventilation resistance 300 (mmH2O / 120mm)

  A plasticizer (triacetin) was added to each tow in an amount of 9% by weight based on the tow weight. S80 was used as a molding paper (test paper) for connecting two filter plugs.

  The prepared fragrance capsule-containing filter was placed on an elastic rubber in the same manner as in Example 1, and the fragrance capsule was crushed by applying pressure from above with a pressure-sensitive shaft of a rheometer (see FIG. 5B). As a comparative example, the fragrance capsule was placed alone on the elastic rubber according to the same method as in Example 1, and the fragrance capsule was crushed by applying pressure from above with the pressure-sensitive axis of the rheometer (see FIG. 5B). Each indentation distance (mm) and load (N) were measured.

  The measurement results are shown in FIG. 5C.

  Compared to the case of the fragrance capsule alone, the fragrance capsule-containing filter has a repulsive force due to the filter plug, so that it is difficult to apply a load until the test paper reaches the fragrance capsule by pressing. After reaching (after the indentation distance exceeded about 3 mm), the load was easily applied. Therefore, in the case of the fragrance capsule alone, the fragrance capsule was crushed when a load of about 25.3 N was applied at an indentation distance of about 2.1 mm, whereas the fragrance capsule-containing filter had an indentation of about 4.4 mm. The perfume capsules were crushed when a load of about 37.2 N was applied at a distance.

  From this result, if the perfume capsule in the filter is pressed with a finger from the top of the test paper, it is difficult to apply a load until the test paper reaches the perfume capsule, so the push distance until the test paper reaches the perfume capsule is short. It turns out that it is preferable to do. The indentation distance until the test paper reaches the perfume capsule can be shortened by increasing the size of the perfume capsule, thereby further improving the ease of crushing the perfume capsule.

Example 4 A filter in which a fragrance capsule is disposed in a hollow portion between filter plugs A fragrance capsule-containing filter was prepared in the same manner as in Example 3 except that the tow of the suction port side and the cut side filter plug was changed as follows.

Suction side and carved side filter plugs Single yarn fineness 5.0 (g / 9000m)
Total fineness 35000 (g / 9000m)
7000 fibers
Ventilation resistance 270 (mmH2O / 120mm)

  No plasticizer (triacetin) was added to the tow.

  The perfume capsules in the prepared filter were similarly crushed, and the indentation distance (mm) and the load (N) were measured. The measurement results are shown in FIG.

  In the fragrance capsule-containing filter of this example, since soft tow was used, the repulsive force by the filter plug could be made smaller than that of the fragrance capsule-containing filter of Example 3. Therefore, the fragrance capsule-containing filter of Example 3 was crushed when a load of about 37.2 N was applied at an indentation distance of about 4.4 mm, whereas the fragrance capsule-containing filter of this example was about The perfume capsules were crushed when a load of about 23.2 N was applied at an indentation distance of 4.5 mm.

  From this result, it can be seen that when a soft filter medium is used, the repulsive force by the filter plug when the perfume capsule-containing filter is pushed with a finger is small, so that the load during crushing the perfume capsule can be reduced. Thus, the ease of crushing a fragrance | flavor capsule can also be improved further by use of a soft filter medium.
