Description

cigarette

The present invention relates to a cigarette.

Conventionally, techniques for holding various substances have been developed to add value to cigarettes. For example, there is a technique in which a fragrance is added to a filter to change or adjust the flavor. There is also a technique of adding activated carbon to the filter.

As a technique for providing such added value, for example, in a filter wound with a wrapping material, a paper or the like is used so that an annular gap or pocket is defined between the crimp portion and the surrounding wrapping portion. There has been disclosed a technique of providing dumbbell-shaped members that are surrounded around their ends by a formed spiral or cylindrical wrapping (see Patent Document 1). The void formed between the edge and the wrapping is filled with a smoke deformation medium, eg activated carbon particles, and there is no flashing in the crimp part, so that the uniformity and effectiveness of the product when used as a cigarette smoke filter Is to improve.

US Pat. No. 5,632,286

Conventional techniques have been aimed at mixing mainstream smoke and perfume or mainstream smoke and air. Here, the inventors of the present case have focused on the point that new added value can be created by increasing and separating the independence of mainstream smoke and fragrance.

For example, in the technique described in Patent Document 1, an annular gap or pocket is provided between the crimp portion and the surrounding wrapping portion to divide the structure. However, the cigarette described in Patent Document 1 allows air to pass between the crimp portion and the gap, and it has not been possible to provide each with a highly independent function.

This invention is made in view of such a subject, and makes it a subject to provide the cigarette which can attract | suck by isolate | separating a mainstream smoke component and a fragrance | flavor component as much as possible.

The cigarette according to the present invention includes a rod including a cigarette, a filter portion provided continuously with one end of the rod, a fragrance capsule disposed in the filter portion and containing a fragrance, and disposed in the filter portion. A partition member for partitioning the mainstream smoke flow path passing through the fragrance holding portion for containing the fragrance capsule, and blocking the mainstream smoke and fragrance components from passing between the flow path and the fragrance holding portion; A covering member made of paper or film that covers a part of the perfume holding part and can release the components of the perfume out of the perfume holding part.

According to the present invention, it is possible to provide a cigarette that can be sucked by separating mainstream smoke components and fragrance components as much as possible.

The cigarette according to this embodiment holds a fragrance in the filter portion. The filter portion has a partition member that partitions the mainstream smoke flow path and the perfume holding unit that holds the perfume. Moreover, the side surface of the section in which the fragrance holding portion is formed in the filter portion is covered with a member capable of transmitting the fragrance component. As a result, the mainstream smoke is introduced into the user's oral cavity via the flow path, and the fragrance component is introduced into the user's nasal cavity from the side of the filter portion without substantially mixing with the mainstream smoke. That is, the user can separate and suck the mainstream smoke and the fragrance component as much as possible. Hereinafter, cigarettes according to embodiments will be described with reference to the drawings.

<Configuration of cigarette>
FIG. 1 shows a perspective view of a cigarette according to the present embodiment. The cigarette 1 according to the present embodiment has a substantially cylindrical shape, a tobacco rod 10 in which a cigarette is wrapped with a wrapping paper, and a filter unit 20 including a segment in which a filter tow of a fiber material such as cellulose acetate is wrapped with a wrapping paper. have. In the present embodiment, the unit of the constituent parts arranged in the axial direction of the cigarette 1 is called a segment. The axial direction is the longitudinal direction of the cigarette 1. Each segment may be wound with a wrapping paper. Further, the plurality of segments may be further connected by being wound with a wrapping paper such as chip paper, and the cigarette 1 may be formed. For example, a tobacco rod 10 that is a segment in which a cigarette is wrapped with a wrapping paper, and a filter unit 20 that includes a segment in which a filter tow is wrapped with a wrapping paper are further wrapped in chip paper and connected in the axial direction of the cigarette 1 .

FIG. 2 shows the internal structure of the filter unit 20. The filter unit 20 includes a fragrance segment that holds a fragrance capsule and a filter segment that includes a filter tow. In the filter unit 20 shown in FIG. 2, the fragrance segment includes a partition member 201 and a fragrance capsule 206 described later. The

filter segments

202 and 203 also include a filter tow of a fiber material such as cellulose acetate.

FIG. 3 is a perspective view of the partition member 201. The partition member 201 includes a cylindrical shaft portion 2011 and

wall portions

2012 and 2013 provided at both ends of the shaft portion 2011 in the axial direction. The appearance of the partition member 201 can be said to be a drum shape or a dumbbell shape. And the axial part 2011 has the through-hole 208 used as the flow path for allowing mainstream smoke to pass along an axial direction. The axial direction corresponds to the longitudinal direction of the cigarette 1 and the partition member 201. Moreover, let the longitudinal direction of the cigarette 1 and the division member 201 be a vertical direction for convenience. In FIG. 3, the through hole 208 is provided as a region around the axis of the partition member 201 (also referred to as an “axis part” for convenience), but the position of the through hole 208 is not necessarily in the axis of the partition member 201. Is not limited. Here, the axial center refers to an axis that is the center of the cigarette 1 and the partition member 201 along the center of the cross section of the cigarette 1 and the partition member 201. The through hole 208 may be hollow, for example, or may be filled with acetate tow. Further, the outer periphery of the cross section of the shaft portion 2011 is smaller than the outer periphery of the cross section of the filter portion 20 and the outer periphery of the cross section of the

walls

2012 and 2013. The outer peripheries of the cross sections of the

walls

2012 and 2013 are substantially the same size as the outer peripheries of the cross section of the filter unit 20, and block between the shaft part 2011 and a wrapping paper 204 described later.

The partition member 201 is directly or indirectly wrapped with a wrapping paper 204. In addition, a fragrance holding portion 205 which is a space for holding a fragrance capsule is formed by being surrounded by the shaft portion 2011, the

wall portions

2012 and 2013 of the partition member 201, and the wrapping paper 204. The fragrance holding unit 205 holds a fragrance capsule 206. In the present embodiment, the fragrance holding portion 205 is provided in an annular shape around the through hole 208 in a sectional view. The perfume capsule 206 is indicated by a two-dot chain line in FIG. Further, the distance from the outer peripheral side surface of the shaft portion 2011 to the wrapping paper 204 is also referred to as the depth of the fragrance holding portion 205 for convenience.

The fragrance capsule 206 is, for example, a capsule containing a liquid or powdery fragrance component. When it is liquid, it may be an aqueous fragrance or an oily fragrance. Moreover, the user can destroy the capsule by pressing the surface of the capsule. When the capsule is broken, the fragrance component inside the capsule is released, and at least a part of the fragrance component is vaporized or aerosolized. The user can inhale the vaporized or aerosolized fragrance component and feel the flavor.

Also, the wrapping paper 204 wrapping the fragrance segment has a vent hole 207 for releasing the vaporized or aerosolized fragrance component to the outside of the wrapping paper. The filter unit 20 in FIG. 2 has two rows of vent holes 207 along the circumferential direction on the side surface. The side surface refers to the outer periphery of the filter unit 20 wrapped with the wrapping paper 204. In addition, the vent hole 207 is located around the outer periphery of the fragrance holder 205 in a cross-sectional view. By using such a partition member 201, the fragrance component is directly introduced into the user's nasal cavity with little mixing with the mainstream smoke, and is also attached to the user's finger holding the fragrance holding portion 205 or the vicinity thereof. In addition, the odor of cigarettes adhering to the user's finger can be reduced (ie, smelling).

The material of the wrapping paper 204 is a flexible material, such as paper or film. Then, the user can press the fragrance capsule 206 held in the fragrance holding unit 205 with a finger from the outside of the wrapping paper 204.

Moreover, it is preferable that the material of the partition member 201 is a material that can block transmission of mainstream smoke and fragrance components. Specifically, it is preferable to use polyamide, silicon, polyvinyl chloride, fluorine resin, or the like as the material of the partition member 201.

Also, by using the fragrance capsule 206, the user can release the fragrance component at a desired timing by pressing the fragrance segment and breaking the fragrance capsule 206.

According to the cigarette 1 shown in the present embodiment, the mainstream smoke is introduced into the user's oral cavity through the flow path 208, and the fragrance component is used from the side of the filter unit without being substantially mixed with the mainstream smoke. It is introduced into a person's nasal cavity. That is, the user can separate and suck the mainstream smoke and the fragrance component as much as possible.

The embodiment of the present invention has been specifically described above, but the present invention is not limited to the configuration as described above. Next, various modifications that can be applied to the embodiment of the present invention will be described.

<Modification>
The shape of the partition member 201 is not limited to the drum shape or the dumbbell shape as shown in FIG. For example, you may employ | adopt the division member 201a shown in FIG. The partition member 201a has

wall portions

2012a and 2013a similarly to the partition member 201 shown in FIG. 3, but the side surface of the shaft portion 2011a (that is, the bottom surface of the fragrance holding portion 204) is the axis of the partition member 201a. The curved surface is narrowest and narrowest near the center of the direction. In the example of FIG. 4, when the user crushes the fragrance capsule with the finger, the shape of the shaft portion 2011a of the fragrance holding portion is adapted to the finger.

Further, the partition member 201b shown in FIG. 5 may be adopted. The partition member 201b includes a shaft portion 2011b and

wall portions

2012b and 2013b, similarly to the partition member 201 illustrated in FIG. The partition member 201b further has a wall portion 2014b near the center in the axial direction of the partition member 201b. That is, in the example of FIG. 5, two fragrance | flavor holding | maintenance parts are provided. A plurality of fragrance holding parts hold fragrance capsules of different components, and some fragrance holding parts hold capsules containing a deodorant for removing the smell of cigarettes attached to fingers. You may make it do.

Further, the partition member 201c shown in FIG. 6 may be adopted. The partition member 201c has a shaft portion 2011c similarly to the partition member 201 shown in FIG. 3, but the

wall portions

2012c and 2013c have a spherical shape having a through hole. Even if it is a partition member of such a shape, a fragrance | flavor can be hold | maintained to a fragrance | flavor holding | maintenance part.

Further, a partition member 201d shown in FIG. 7 may be adopted. The partition member 201d has two truncated cones each having a through hole in the axial center portion, and has a shape in which the smaller bottom surface of each truncated cone is brought into contact. The partition member 201d in FIG. 7 has no boundary between the shaft portion 2011 and the

walls

2012 and 2013, but the partition member 201 shown in FIG. It is the same. Therefore, even if it is a partition member of such a shape, the fragrance | flavor holding | maintenance part 205 can be provided between a recessed part and a wrapping paper, and the fragrance | flavor capsule 206 can be hold | maintained.

In the example of FIG. 3, the shaft portion 2011 is configured to be fitted to the

wall portions

2012 and 2013. For example, the shaft portion 2011 and the

wall portions

2012 and 2013 may be integrally formed, The partition member 201 may be manufactured by combining shape members.

Moreover, when the through-hole 208 used as the flow path of mainstream smoke is cylindrical shape and hollow, it is preferable that the diameter of the through-hole 208 is 0.5 mm or more. If it is such a magnitude | size, mainstream smoke can be passed suitably in normal smoking. Moreover, if the cross-sectional area of the through-hole 208 is about 0.2 mm < ² > or more, mainstream smoke can be passed suitably.

2 shows the filter unit 20 including three segments, but the number of segments is not limited to three. For example, it is good also as the filter part 20 which consists of one fragrance | flavor segment. Moreover, it is good also as the filter part 20 which consists of two segments, one fragrance | flavor segment and one filter segment. When two or more segments are included, it is preferable that at least one filter segment is arranged closer to the mouth side than the fragrance segment. The user holds the segment provided on the mouthpiece side in the mouth. Therefore, by providing the filter segment on the side of the mouthpiece, the filter segment can be given a role of being a part of the mouth, and can be separated from the part including the fragrance capsule. In this way, when the user holds the filter segment in his / her mouth, the fragrance segment is located in the vicinity of the user's nasal cavity, so that the fragrance component can be suitably introduced into the nasal cavity. The filter is not limited to an acetate filter, and may be a charcoal filter or the like.

The number and size of the fragrance capsules 206 are not limited to the embodiment. When the diameter of the fragrance capsule 206 is made smaller than the height of the walls 2012 and 2013 (that is, the depth of the fragrance holding section 205) in the partition member 201, the fragrance capsule 206 is held by the fragrance holding section 205. Furthermore, it is possible to suppress the occurrence of irregularities in the outer shape of the cigarette 1. The size of the fragrance capsule 206 is preferably 0.1 mm to 3.0 mm, and more preferably 0.5 mm to 1.5 mm. The mass of the fragrance capsule 206 is preferably 0.001 mg to 25 mg, more preferably 0.1 mg to 3.0 mg. The perfume capsules held by the perfume holding unit 205 may be one or plural. When holding a plurality of capsules, the total amount of capsules is preferably 0.5 mg to 500 mg, more preferably 1 mg to 100 mg. Further, in the fragrance holding unit 205, the fragrance capsule may be fixed or may not be fixed. The means for fixing is not particularly limited, but the fragrance capsule 206 can be fixed using a double-sided tape or an adhesive or the like.

The fragrance contained in the fragrance capsule 206 is not particularly limited. For example, lime oil, yuzu oil, berry oil, coffee oil, menthol and the like can be suitably used. In particular, the flavor of lime oil, yuzu oil, berry oil, coffee oil, and the like can change greatly when mixed with mainstream smoke. That is, it has been particularly difficult to taste the original flavor of a fragrance. However, if it is a cigarette mentioned above, a fragrance | flavor component can be isolate | separated from mainstream smoke and can be introduce | transduced into a user's nasal cavity, and a user can taste the original flavor of a fragrance | flavor.

Also, the wrapping paper 204 is preferably a paper or film material that does not break when the user presses with a finger from the outside of the fragrance holding unit 205 to crush the fragrance capsule 206. For example, a cellulose film may be used.

Various materials and configurations can be used for the wrapping paper 204. When the wrapping paper 204 is paper, the basis weight of the wrapping paper 204 is preferably 10 g / m ² to 500 g / m ^{2, and} more preferably 20 g / m ² to 300 g / m ² . Further, when the air hole 207 is provided in the wrapping paper 204, the wrapping paper 204 may not have a property of transmitting the fragrance component. Therefore, the air permeability of the wrapping paper 204 may be 0 ml / min. When the air hole 207 is not provided in the wrapping paper 204, it is preferable that the wrapping paper 204 has a property of transmitting the fragrance component. Therefore, the air permeability of the wrapping paper 204 is preferably larger than 0 ml / min.

When providing the vent holes 207, the number and size of the vent holes 207 are not limited to the embodiment. Since the wrapping paper 204 used in the present invention only needs to be able to transmit the perfume component to the outside, the wrapping paper 204 provided with one or more air holes 207 as described above may be used, or the air holes 207 may be perforated. Alternatively, a paper or a film having air permeability may be used. By setting it as such a structure, it is possible to discharge | release a fragrance | flavor component out of a fragrance | flavor holding | maintenance part efficiently. The diameter of the vent hole 207 is preferably 0.001 mm to 2.7 mm, and more preferably 0.05 mm to 1.4 mm. Further, the number of the vent holes 207 is preferably 1 to 200, and more preferably 10 to 100. If the size and number of the vent holes 207 are in the above range, the vent holes 207 can more suitably release the fragrance component. Further, the air holes 207 may be provided on the entire side surface of the fragrance holding unit 205 and at equal intervals. In this way, the vent hole 207 can efficiently release the fragrance component.

Further, it is preferable to use a material having water resistance or oil resistance for the wrapping paper 204 according to the nature of the fragrance. If the wrapping paper 204 has water resistance or oil resistance, weakening of the wrapping paper 204 derived from the fragrance component when the fragrance component has oozed into the wrapping paper 204 can be suppressed. That is, the wrapping paper 204 is not easily torn even by the user's pressing. Further, by adopting such a configuration, when the user crushes the fragrance capsule 206, the fragrance component soaks into the wrapping paper of the cigarette 1 so that the liquid fragrance component adheres directly to the user's finger, and the user The odor of cigarettes attached to the fingers can be reduced more effectively.

The above modifications can be combined as much as possible.

<Example 1>
Next, an example of a more specific configuration will be described. In this example, the partition member 201 shown in FIG. 3 was formed as follows.

FIG. 8 shows a longitudinal sectional view of the partition member 201. A polyurethane tube was used as the material of the partition member 201. The partition member 201 is formed by fitting

wall portions

2012 and 2013 to both ends of the shaft portion 2011. That is, the outer diameter of the shaft portion 2011 is substantially the same as the inner diameters of the

walls

2012 and 2013, and corresponds to the width 1L in FIG. Moreover, the inner diameter (that is, the diameter of the through hole 208) 2L of the partition member 201 was about 2 mm.

For the production of the fragrance capsule, an encapsulation device “B-390” (manufactured by BUCHI) was used. In the perfume capsule, calcium alginate was used as a membrane material, and a lime oil solution was used as an inclusion. That is, using a double concentric nozzle, using edible oil as a solvent from the inner nozzle, a solution containing 20% by mass of lime oil with respect to the solvent, and an aqueous solution containing 1.5% by mass of sodium alginate from the outer nozzle Were simultaneously added dropwise to an aqueous solution containing 10% by mass of calcium chloride to obtain 100 perfume capsules containing a 20% by mass lime oil solution. The minimum value of the particle size of the obtained perfume capsules was 1.0 mm, and the maximum value was 1.5 mm. The average particle size was 1.1 mm.

The particle size of the fragrance capsules was obtained by arranging 100 obtained fragrance capsules in a line without any gaps, measuring the length with calipers, and calculating the average value of the particle diameter per particle. Furthermore, this was performed 10 times, the average value of 10 times was calculated, and the average particle size of the fragrance capsule was calculated. Moreover, the produced fragrance | flavor capsules were 0.8 mg per grain average, and crushing hardness (fracture hardness) was about 2N (Newton).

Moreover, a double-sided tape was wound around the fragrance holding part 205 side of the partition member 201, that is, the shaft part 2011, and a total of about 100 mg of the fragrance capsule 206 was stuck on the double-sided tape. In addition, the depth of the fragrance | flavor holding | maintenance part 205 was provided larger than the diameter of the fragrance | flavor capsule, and the fragrance | flavor capsule was arrange | positioned as 1 layer on the double-sided tape. By doing in this way, the change of the shape of the cigarette on the external appearance was able to be suppressed.

Further, “New Bright Foam” (manufactured by Daio Paper Co., Ltd.) was used for the wrapping paper of the partition member 201. The wrapping paper was perforated so that a total of 100 apertures were arranged, 10 rows in the circumferential direction of the fragrance segment and 10 rows in the axial direction. The size of each aperture was about 0.1 mm in diameter.

Further,

filter segments

202 and 203 were produced by winding filter tow with a wrapping paper. Then, the

filter segments

202 and 203 were brought into contact with both ends of the partition member 201, and the three segments were wound with wrapping paper to form the filter unit 20 (triple segment filter). Note that the filter segment 203 provided on the suction side had a length of about 8 mm in the axial direction of the cigarette 1.

In addition, the tobacco rod 10 was formed by wrapping a cigarette having a total amount of 0.6 g with a blending ratio of 50% yellow species and 50% Burley species with a wrapping paper having a basis weight of 27 g / m ² . Then, one end of the tobacco rod 10 and one end of the filter unit 20 were brought into contact with each other and wound with chip paper, and the cigarette rod 10 and the filter unit 20 were connected to form the cigarette 1.

<Comparison between oral presentation and nasal presentation>
The difference in perfume intensity and preference perceived by humans was evaluated for the case where the fragrance was introduced from the oral cavity and the case where the fragrance was introduced from the nasal cavity. Specifically, 10 μL of lime oil whose main component is 20% limonene and 20% 1,8-cineole is injected into a 6 L pressure vessel with a syringe and added with air so that the container has a gauge pressure of 2 atm. A pressed fragrance presentation device was produced. From the produced device, the fragrance was presented directly into the oral cavity and nasal cavity for 0.4 seconds at a gauge pressure of 0.2 atm, and fragrance intensity evaluation and preference evaluation were performed, respectively.

FIG. 9 shows the evaluation axis used for strength evaluation. For the strength evaluation, an evaluation axis of LMS (Labeled Magnitude Scale) was used. The evaluation axis is “Strongest imaginable”, “Very Strong”, “Strong”, “Moderate”, “Weak”, “Barely Detective” No) ”at six stages.

FIG. 10 shows the results obtained by converting the strength evaluation results by the 10 evaluators into numerical values and calculating the geometric mean for the nasal cavity presentation and the oral cavity presentation. The vertical axis in FIG. 10 is an evaluation axis in LMS. From “Lower (1)” to “Upper” (100) in FIG. 10, “Barely Detective (very little)” to “Strongest imaginable” is plotted at unequal intervals.

The average value of nasal cavity presentation is 19.9, and is plotted in a triangle at a position slightly higher than “Moderate (16.3)” in FIG. In addition, the average value of oral presentation is 6.46, which is plotted in a square around “Weak (5.76)” in FIG. That is, it was evaluated slightly stronger than “Moderate” for nasal presentation, and “Weak” for oral presentation. Therefore, it can be said that when the perfume ingredient having the same concentration is directly presented to the nasal cavity, the perfume intensity is significantly stronger than that presented directly to the oral cavity. From the above results, it can be seen that the perfume can be perceived more efficiently when presented to the nasal cavity than to the oral cavity if the perfume components have the same concentration.

Also, the following scale axis was used to evaluate the preference. The scale axis is “Very Favorite (3)”, “Like (2)”, “Slightly Like (1)”, “None” (0), “Slightly Dislike (−1)”, “Hate” (−2) ) ”And“ Very disliked (−3) ”have seven steps at equal intervals.

On the other hand, the results of calculating the arithmetic mean for the nasal cavity presentation and the oral cavity presentation are shown in FIG. The vertical axis in FIG. 11 indicates the degree of preference, and corresponds to “very dislike” from “very dislike” from the lower end (−3) to the upper end (3).

The average value of nasal cavity presentation is 2.0, and is plotted in a triangle on “like (2.0)” in FIG. In addition, the average value of oral presentation is −0.83, and is plotted in a rectangle at a position slightly higher than “Slightly dislike (−1)” in FIG. That is, it was evaluated as “I like” in the nasal cavity presentation, and slightly more “neither” than in “Slightly disliked” in the oral presentation. Therefore, it can be said that when the fragrance component having the same concentration is directly presented to the nasal cavity, the preference level is significantly improved as compared to the direct presentation to the oral cavity. From the above results, it was found that the perfume ingredients having the same concentration are perceived more preferably when presented in the nasal cavity than when presented in the oral cavity.

From the above, the user can perceive the fragrance ingredient more strongly when it is introduced from the nasal cavity than the fragrance ingredient is introduced from the oral cavity of the user. That is, the user can feel the fragrance component efficiently. Also, if the mainstream smoke and the fragrance component are separated as much as possible, the mainstream smoke is introduced into the user's mouth, and the fragrance component is introduced into the user's nasal cavity, the user can perceive the fragrance component more preferably. Can do.

Moreover, the cigarette 1 which concerns on this Embodiment has a fragrance | flavor holding | maintenance part on the radial direction outer side near a suction mouth, and when a user holds a cigarette, it can discharge | release a fragrance | flavor component from the position near a nasal cavity. it can. That is, the cigarette 1 according to the present embodiment can efficiently introduce the fragrance component into the nasal cavity of the user and can make the fragrance component perceived by the user more preferably.

<Hardness of partition member>
In order to evaluate the ease of crushing and the crushing comfort of the capsule due to the difference in the hardness of the structure, partition members according to Examples 2 to 6 below were produced.

<Example 2>
As a material for the partition member, a silicon tube was used instead of the polyurethane tube used in Example 1. Other configurations were the same as those in Example 1.

<Example 3>
As a material for the partition member, a polyvinyl chloride tube was used instead of the polyurethane tube used in Example 1. Other configurations were the same as those in Example 1.

<Example 4>
As a material for the partition member, a Tygon (registered trademark) tube (a tube made of an olefin elastomer material) was used instead of the polyurethane tube used in Example 1. Other configurations were the same as those in Example 1.

<Example 5>
Instead of the polyurethane tube used in Example 1, nanotubes were used as the partition member material. Other configurations were the same as those in Example 1.

<Example 6>
As a material for the partition member, a soft polyethylene tube was used instead of the polyurethane tube used in Example 1. Other configurations were the same as those in Example 1.

Further, the hardness of the tubes used in Examples 1 to 6 was measured using a creep meter “RHEONERII RE2-30005S (manufactured by YAMADEN)”. Specifically, a force was applied perpendicular to the axial direction of the tube used for the shaft portion of the partition member (that is, in the radial direction of the tube), and the force required to deform 0.5 mm was measured. Table 1 shows the arithmetic average of the results measured three times for each example.

<Evaluation of ease of crushing and crushing of perfume capsules>
For Examples 1 to 6, the ease of crushing and the crushing comfort of the capsules were evaluated. For the evaluation of ease of crushing, “very easy to crush (3)”, “easy to crush (2)”, “slightly easy to crush (1)”, “neither (0)”, “slightly crushing (−1 ) ”,“ Difficult to crush (−2) ”, and“ Difficult to crush (−3) ”were used with a scale axis having seven steps at equal intervals. In addition, the evaluation of crushing comfort is "very good crushing comfort", "good crushing comfort", "slight crushing comfort", "neither", "slight crushing comfort", "smashing comfort" A scale axis having seven steps of “bad” and “very uncomfortable” at equal intervals was used.

For the cigarettes according to Examples 1 to 6, the arithmetic averages of the evaluation values of the ease of crushing the capsules by 10 evaluators were calculated. Similarly, for the cigarettes according to Examples 1 to 6, the arithmetic averages of the evaluation values of crushing comfort by 10 evaluators were calculated. FIG. 8 shows these results. The vertical axis in FIG. 8 corresponds from the lower end (−3) to the upper end (3), from “Very hard to crush” to “Very easy to crush”, and “Very bad to crush” to “Very crushing comfort”. .

In any example, the evaluator was able to crush all the fragrance capsules. Moreover, mainstream smoke and a fragrance | flavor component are isolate | separated, a fragrance | flavor component is introduce | transduced into an evaluator's nasal cavity from the vent hole 207, and mainstream smoke is introduce | transduced into an evaluator's oral cavity through the through-hole 208 used as the flow path of a mainstream smoke. The effect of being able to do so was exhibited in any of the examples.

However, as shown in FIG. 8, as for the ease of crushing and the crushing comfort of the fragrance capsule, a difference appeared in the results depending on the hardness of the partition member. The ease of crushing the fragrance capsule is about -3.0 when the tube hardness (ie, the force required for deformation of 0.5 mm) is 4.9 N, and -1.7 when the hardness is 8.5 N. When the hardness is 14.0N, about 0, when the hardness is 20.3N, about 1.7, when the hardness is 31.7N, about 2.7, when the hardness is 57.5N It was about 2.7. Similarly, the crushing comfort of the fragrance capsule is about -2.7 when the tube hardness is 4.9N, about -1.3 when the hardness is 8.5N, and when the hardness is 14.0N. Was about 0.3 when the hardness was 20.3N, about 2.7 when the hardness was 31.7N, and about 2.3 when the hardness was 57.5N. .

Accordingly, the hardness of the partition member is preferably 1N or more, preferably 15.0N to 60.0N, and the force required to deform the tube used as the partition member by 0.5 mm is preferable. 0N to 60.0N is more preferable, and 25.0N to 40.0N is particularly preferable. With such a value, it is possible to provide a comfortable split feeling to the user.
