Embodiments of the invention

Embodiments of the invention are described below.

A cigarette filter according to one embodiment of the invention comprises a filter housing and an aroma-generating element comprising a flavor carrier formed from one or more separate threads and a plurality of flavor-generating components carried by the flavor carrier. The aroma-generating element is included in the filter housing, and extends along the central axis of the filter housing. One aroma-generating component emits an aroma different from the aromas of another one or more aroma-generating components. The aroma-generating behavior of one aroma-generating component is different from the aroma-generating behavior of another one aroma-generating component. The aroma-generating component is selected from the group consisting of: pure flavoring; pure flavoring combined with cyclodextrin; and pure flavor combined with dextrin.

The filter housing containing the aroma-generating element contains a tow, for example, of acetate fiber, and is usually in the form of a column. The length of the filter housing is usually from 100 mm to 140 mm, and the diameter is usually from 15 mm to 26 mm.

The flavoring element comprises a flavoring carrier formed from one or more separate threads and a plurality of flavoring components that are carried by the flavoring carrier. The aroma-generating element may consist of a carrier of flavoring and a plurality of aroma-generating components.

A thread representing a flavor carrier may consist of a single fiber (filament) or a bundle of multiple fibers (filaments) and may be a single or complex thread. Complex yarns contain various textured yarns.

The material of the thread is not particularly limited. The thread can be formed, for example, from a natural material, for example: cotton, wool or silk, or from a synthetic material, for example: polypropylene, polyethylene or cellulose acetate.

The diameter of the thread is usually from 0.3 mm to 2.5 mm, and preferably from 0.7 mm to 1.5 mm. The length of the thread is usually the same as the length of the filter housing. The thread usually runs along the central axis of the filter housing, along the entire length of the filter housing, i.e. from the far end to the proximal end of the filter housing. The outer circumferential surface of the filter housing is wrapped with a filter wrapper, for example of tissue paper, to obtain a filter.

The aroma-generating component is selected from the group consisting of: (i) a pure flavoring; (ii) a pure flavor combined with cyclodextrin; and (iii) a pure flavor combined with dextrin. Pure flavoring is the flavoring substance itself. Examples of a pure flavor include: acetanisole, acetophenone, acetylpyradine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, transanetol, star anise badian oil, apple juice, Peruvian balsam oil, yellow beeswax, absolute, benzaldehyde resin, resino benzyl alcohol, benzyl benzoate, benzyl phenyl acetate, benzyl propionate, 2,3-butanedione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamom oil, absolute carob oil, β-carotene, carrot juice, L-carvone, β- car iofillen, Chinese cinnamon oil, cedar oil, celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acid, cinnamon alcohol, cinnamyl cinnamate, citronella oil, DL-citronellol, clary sage extract, cocoa, coffee, cognac oil, coriander oil, cumic aldehyde, wormwood oil, δ-decalactone, γ-decalactone, capric acid, dill greens, 3,4-dimethyl-1,2-cyclopentanedione, 4,5-dimethyl-3-hydroxy-2,6-dihydrofuran -2-one, 3,7-dimethyl-6-octenoic acid, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,6-dim ethyl pyrazine, ethyl 2-methyl butyrate, ethyl acetate, ethyl butyrate, ethyl hexanoate, ethyl isolerate, ethyl lactate, ethyl laurate, ethyl lavulinate, ethyl maltol, ethyl octanoate, ethyl oleate, ethyl palmitate, ethyl phenyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanyl, ethylpropyl butanethyl, ethylpropyl butanate, ethylpropyl butanate, ethylpropyl butanate, ethylpropyl butanyl, 5 or 6) -dimethylpyrazine, 5-methyl-3-hydroxy-4-methyl-2 (5H) -furanone, 2-ethyl-3-methylpyrazine, eucalyptol, absolute fenugreek oil, absolute genetta oil, mustard root infusion, geraniol, geranyl acetate, grape juice, guaiacol, guayava extract, δ-heptalact n, γ-hexalactone, caproic acid, cis-3-hexen-1-ol, hexyl acetate, hexyl alcohol, hexyl phenyl acetate, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4- (3-hydroxy-1 -butenyl) -3,5,5-trimethyl-2-cyclohexen-1-one, 4- (parahydroxyphenyl) -2-butanone, sodium salt of 4-hydroxyunedanolate, absolute immortelle oil, β-ionone, isoamyl acetate, isoamyl butyrate, isoamyl phenyl acetate , isobutyl acetate, isobutyl phenyl acetate, absolute jasmine oil, coconut infusion, labdanum oil, terpene-free lemon oil, licorice extract, linalool, lina ethyl acetate, oil from the root of the lovage, maltol, maple syrup, menthol (levomenthol), menton, L-methyl acetate, parametoxybenzaldehyde, methyl-2-pyrrolyl ketone, methylanthranylate, methylphenyl acetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methyl absolute mimosa oil, molasses, myristic acid, nerol, nerolidol, γ-nonalactone, nutmeg oil, δ-octalactone, octanal, caprylic acid, orange tree flower oil, orange oil, violet root oil, palmitic acid, list oil peppermint, Paraguayan petigrene oil, phenethyl alcohol, phenethyl phenyl acetate, phenylacetate acid, piperonal, plum extract, propenylguaethol, propyl acetate, 3-propyleneidephthalide, plum juice, pyruvic acid, raisin extract, rose oil, shalam oil , curly mint oil, absolute styrax oil, marigold oil, tea distillate, α-terpineol, terpinyl acetate, 5,6,7,8-tetrahydroquinoxaline, 1,5,5,9-tetramethyl-13-oxacyclo- (8.3.0.0 (4.9)) - tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil (thyme) , tomato extract, 2-tridecanone, trimethyl citrate, 4- (2,6,6-trimethyl-1,3-cyclohexenyl) -2-butene-4-one, 2,6,6-trimethyl-2-cyclohexene-1, 4-dione, 4- (2,6,6-trimethyl-1,3-cyclohexadienyl) -2-buten-4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin , hellebore aldehyde and absolute violet leaf oil.

The aroma-generating component, consisting of a pure flavoring agent, can be applied to the thread by dissolving it in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate and the like, and soaking the thread with a solution. An aroma-generating component, consisting of a pure flavoring agent combined with cyclodextrin, can be applied to the yarn by dispersing it in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate and the like, and impregnating the yarn with suspension. The following can be added to the suspension: emulsifier, for example, sucrose and fatty acid ester; dispersant and antifoam agent. The aroma-generating component, consisting of a pure flavoring agent combined with dextrin, can be applied to the thread by dispersing it in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate and the like, and impregnating the thread with a suspension. The following can be added to the suspension: emulsifier, for example, sucrose and fatty acid ester; dispersant and antifoam agent. By way of example, an aroma-generating component consisting of a pure flavoring combined with dextrin can be obtained as a finely divided powder containing a flavoring by adding flavoring to an aqueous solution of dextrin in which (optionally) an emulsifier is dissolved, and the like, and converting it into an emulsion by mixing in a homogenizing mixer, and by subsequent spray drying using a spray dryer.

One aroma-generating component emits an aroma different from the aroma or aromas of another one or more aroma-generating components. Namely, the pure flavor contained in one flavoring component is a flavoring substance that emits a flavor different from the pure flavor or pure flavors contained in one or more other flavoring components.

The aroma-generating behavior of one aroma-releasing component is different from the aroma-releasing behavior of another one aroma-releasing component. The aroma-generating component, consisting of pure flavoring, emits aroma when smoking a cigarette, mainly in proportion to the amount of tar in the main stream of cigarette smoke passing into the filter. The aroma-generating component, consisting of a pure flavor combined with cyclodextrin (in this case, a pure flavor is interspersed with cyclodextrin), releases the aroma through a specific smoke component in the mainstream smoke of a cigarette (especially a component having a vapor pressure that is distributed as in the liquid phase , and in the solid phase at normal temperature), passing into the filter, and by increasing the "release" of heat when smoking a cigarette. The aroma-generating component, consisting of a pure flavor combined (mixed) with dextrin, mainly releases the aroma through the water present in the main stream of cigarette smoke passing into the filter and by increasing the heat.

Namely, in an aroma-generating component consisting of a pure flavoring agent; and in an aroma-releasing component consisting of a pure flavoring combined with cyclodextrin; and in an aroma-generating component consisting of a pure flavoring combined with dextrin; the amount of flavor emitted by these flavor-generating components is different with each puff when smoking a cigarette. Thus, when smoking a cigarette equipped with a filter containing many different flavor-generating components when smoking a cigarette, one can feel the aroma of the cigarette itself and the mixture of flavors of dissimilar flavors present in varying amounts with each puff when inhaling smoke.

For the manufacture of a filter housing containing an aroma-generating element, for example, the method disclosed in Japanese Patent Application Publication No. 63-38187 may be used. Namely, on a conventional machine for manufacturing cigarette filters, for example, immediately before the process of wrapping the loosened bundle of acetate fibers in a wrapper for the filter and forming a wrapped bundle of fibers in the form of a rod, a guide and a mandrel are installed to guide the thread in a predetermined position in the circumferential direction of the acetate bundle fibers, and the thread is passed through the guide and the mandrel, whereby the thread can be introduced into the bundle of acetate fibers. It is understood that the thread is impregnated with an aroma-releasing component before being introduced into the bundle of acetate fibers, as described above.

According to a first embodiment of the present invention, the flavor carrier is composed of a plurality of individual threads, and the plurality of flavor-generating components can suitably carry different individual threads. A cigarette filter according to a first embodiment of the invention comprises a filter housing comprising a plurality of flavor elements comprising one or more separate strands containing flavor components, and although the filter flavor is the same as the flavor in one flavor element, the filter flavor is different from the flavor in one or more other aroma-generating elements; and in this filter, the flavor-generating behavior of one flavor-generating element is different from the flavor-generating behavior of the other one flavor-generating element. According to a first embodiment, different yarns carrying different aroma-generating components can be dyed in different colors.

According to a second embodiment of the invention, the flavor carrier consists of one or more separate threads, and each individual thread carries a plurality of flavor-generating components containing heterogeneous, pure flavoring agents. In this case, it is preferable that the individual yarn consisted of a plurality of yarns, where the yarn carries an aroma-generating component, and one or more other yarns carry another aroma-generating component, and these yarns are twisted together to form the yarn. Namely, according to the second embodiment, the aroma-generating element consists of one or more separate threads carrying various aroma-generating components.

The cigarette of the invention is equipped with a filter of the invention at one end of the cigarette rod. The cigarette core is similar to the cigarette core of a conventional filter cigarette and consists of a tobacco core, for example a tobacco bag, and a cigarette wrapper wrapped around the outer circumferential surface of the tobacco core. The filter is attached to the cigarette rod by paper for attaching the filter. The length of the cigarette rod is usually from 40 mm to 70 mm, and the diameter may be the same as the diameter of the filter, or, for greater reliability of attaching to the filter with paper for attaching the filter using glue, the diameter may be slightly larger than the diameter of the filter (maximum diameter is 0.5 mm).

These embodiments of the invention are described below with reference to the drawings. In all the drawings, similar objects are denoted by the same reference numbers, and their repeated description is omitted.

1 is an enlarged schematic perspective view of an exemplary filter according to a first embodiment of the invention. The filter 10 shown in FIG. 1 comprises a columnar filter housing 110 consisting of a bundle of acetate fibers held together by a plasticizer, for example triacetin. The filter housing 110 comprises a plurality of aroma-generating elements extending parallel to the central axis of the filter housing 110. A plurality of flavoring elements consists of a plurality of individual threads carrying a flavoring component containing a pure flavoring. One of these aroma-generating elements contains a pure aroma different from the pure aroma contained in one or more other aroma-generating elements. Figure 1 shows two aroma-generating elements 121 and 122 that are inserted into the filter housing 110. For example, flavoring element 121 consists of cotton thread 121a carrying a flavoring component consisting of pure flavor A; and flavoring element 122 consists of a cotton thread 122a bearing a flavoring component consisting of pure flavoring B coupled to cyclodextrin, or pure flavoring C connected to dextrin. Pure flavor A is a flavor other than pure flavor B and / or pure flavor C.

Cotton threads 121a and 122a may be dyed in colors that differ from each other. The outer circumferential surface of the filter housing 110 is wrapped in a filter wrapper 130 to form a filter 10. The filter 10 comprises a front end surface 10a and a base end surface 10b. By attaching the filter 10 to the cigarette rod, the front end surface 10a can be tightly attached to the base end surface of the cigarette rod. The filter area containing the base end surface 10b of the filter 10 is held by the smoker <when smoking a cigarette>.

Figure 2 presents an enlarged schematic perspective view of another exemplary filter according to the first embodiment of the invention. The filter 20 shown in FIG. 2 has a structure similar to that of the filter 10 shown in FIG. 1, except that three aroma-generating elements 221, 222 and 223 are introduced into the filter housing 110. For example, the aroma-generating element 221 consists of a cotton thread 221a carrying an aroma-generating component consisting of pure flavor A; the flavoring element 222 consists of a cotton thread 222a carrying a flavoring component consisting of a pure flavoring agent B connected to a cyclodextrin; and aroma-generating element 223 consists of a cotton thread 223a carrying an aroma-generating component consisting of pure flavoring agent C combined with dextrin. For example, pure flavor A, pure flavor B and pure flavor C are flavors that differ from each other and accordingly emit different flavors. Cotton threads 221a, 222a and 223a may be dyed in colors that differ from each other. For example, cotton thread 221a can be dyed blue, cotton thread 222a can be dyed yellow, and cotton thread 223a can be dyed pink.

FIG. 3 is an enlarged schematic perspective view of an exemplary filter according to a second embodiment of the invention. The filter 30 shown in FIG. 3 has a structure similar to that of the filter 10 shown in FIG. 1, except that instead of the aroma-generating elements 121 and 122, an aroma-generating element 310 consisting of a yarn 310a supporting many aroma-generating components. A yarn 310a bearing a plurality of aroma-generating components can be formed by, for example, twisting together a cotton yarn carrying an aroma-generating component consisting of pure flavor A; a cotton thread bearing an aroma-releasing component consisting of pure flavoring agent B combined with cyclodextrin; and a cotton thread bearing an aroma-releasing component consisting of pure flavoring agent C combined with dextrin. Pure flavor A, pure flavor B, and pure flavor C may be different flavors, and these pure flavors emit different flavors accordingly. Two or more flavoring elements 310 may be introduced into the filter housing 110.

4 is a schematic perspective view in enlarged scale of an example of a filter cigarette according to the invention. The filter cigarette 40 shown in FIG. 4 is provided with a cigarette rod 410 having a front (ignited) end 410a and a base end 410b, and a filter 420 comprising a front end 420a and a base end 420b. For the cigarette rod 410 and the filter 420, the base end 410b of the cigarette rod and the front end 420a of the filter are tightly connected to each other, where the cigarette rod 410 and the filter 420 are connected using filter paper 430. The cigarette rod 410 consists of a tobacco rod 411 with the filling described above and a cigarette wrapper 412 for wrapping the outer periphery of the tobacco rod 411. The filter 420 is formed from a filter according to the invention. For example, filter 420 may be formed from filter 10 shown in FIG. 1, from filter 20 shown in FIG. 2, or from filter 30 shown in FIG. 3.

Fig. 5 is a diagram for explaining changes with each puff of the quantity (delivered quantity) of flavoring coming from the filter 420 into the mainstream smoke of a cigarette passing through the filter 420 when smoking the cigarette shown in Fig. 4, equipped with a filter 20 shown in Figure 2.

For example, the main body 110 of the filter 20 comprises an aroma-generating element (aroma-generating element A) consisting of a cotton thread 221a carrying an aroma-generating component consisting of pure flavor A; an aroma-generating element (aroma-generating element B) consisting of a cotton thread 222a carrying an aroma-generating component consisting of a pure flavoring agent B combined with cyclodextrin; and an aroma-generating element (aroma-generating element C) consisting of a cotton thread 223a carrying an aroma-generating component consisting of a pure flavoring agent C combined with dextrin; where pure flavor A, pure flavor B and pure flavor C are different from each other. The amount of flavoring that enters the mainstream smoke of the cigarette from the flavoring element A gradually increases substantially linearly with each puff (curve a). Although the amount of flavoring that enters the mainstream smoke of a cigarette from flavoring element B is greater than the amount present in flavoring element A from the initial stage to the intermediate tightening step, the amount then gradually decreases, and the amount of flavoring delivered becomes less than the amount of substance present in the flavoring element A, at a later stage of tightening (curve b). Although the amount of flavoring that enters the mainstream smoke of a cigarette from flavoring element C is very small from the initial puff stage to the intermediate state, the amount of flavoring increases rapidly at a later stage of puffing and becomes more than the amount of flavoring substances delivered from flavoring elements A and B ( curve c). Thus, when smoking a filter cigarette according to the invention, the smoker can feel not only the aroma of the cigarette itself, but also a mixture of flavors of dissimilar flavors coming in different quantities with each puff.

Examples

Although the invention is described below with reference to examples, it is not limited to the following examples.

Example 1

In this example, a filter was made having the structure shown in FIG. 1; the filter was attached to the cigarette rod to obtain a filter cigarette, and thus a cigarette was obtained for organoleptic evaluation.

More specifically, according to the method disclosed in Japanese Patent Publication No. 63-38187, two devices were provided for making aroma-generating elements consisting of: packing yarn No. 20/8, according to English numbering, from bleached cotton; a fragrance tank; flavoring pump; devices for applying flavoring, etc .; for installation on a conventional filter manufacturing machine; a solution of levomenthol (concentration - 70%) in polypropylene was poured into the bath for the flavor of one of the devices for making aroma-releasing elements, and α-cyclodextrin, including ethyl butyrate (sweet flavor) (concentration - 50%), dispersed in polypropylene glycol, was poured into the bath for flavor another device for the manufacture of aroma-generating elements. Both devices were actuated: a device for manufacturing aroma-generating elements, and a machine for manufacturing filters, and the required long filter housing was manufactured. The parameters of the acetate fiber tow, representing the filter housing, were as follows: fiber fineness - 2.5 denier (2.78 dtex); total fineness of the tourniquet - 35,000 denier (3885 tex = 3.9 kteks); the cross-sectional shape of each fiber was Y-shaped. The breathability in the filter wrapper was 1000 CU (Cholester units); the surface density was 24.0 g / m ² and the width was 26.5 mm. The circumference of the resulting long filter housing was 24.5 mm, and the length was 100 mm.

The filter cigarette was made on a conventional cigarette hoisting machine using: a long filter body, tobacco filling, cigarette wrapper and filter paper to make a cigarette core available for purchase of a cigarette product (SALEM ALASKA). In this case, the long filter housing was divided into four parts, and a 25 mm long filter for one cigarette was connected end-to-end with a cigarette stick.

Parameters of the cigarette rod: the circumferential length was 24.5 mm and the length was 84 mm.

20 filter cigarettes made in this way were packed in a regular cigarette pack and the cigarette pack was sealed. Packs of cigarettes were stored for one month in the environment at a temperature of 22 ° C and a relative humidity of 60%. After storage, filter cigarettes were removed from the pack. Cigarettes were handed out for smoking to seven test participants, and they gave an organoleptic evaluation of the sensations from the inhaled aroma.

During the organoleptic evaluation, the following indicators of sensations from the inhaled aroma were recorded when smoking one cigarette, with each puff (from the first puff to the seventh puff).

Perfection Indicators

Menthol sensation: seven experts participating in the tests from the applicant company, who were professionally prepared for tests to assess the sensations of inhaled aroma of a cigarette, and were instructed to assess the sensations of inhaled aroma, and recorded the development of sensations of inhaled aroma at an organoleptic assessment in accordance with following standards, and then calculated the average values of the estimates.

In cigarette products sold by the applicant’s company, the organoleptic evaluation of the menthol aroma sensation of the cigarette product, which produced the most intense menthol aroma, was taken as 2.0 points (benchmark), and the organoleptic evaluation of the menthol aroma sensation of the cigarette product, which did not cause the menthol aroma sensation, was taken as 1.0 point (benchmark). The evaluation of the cigarette manufactured in Example 1 relative to both reference ratings was determined in increments of 0.1 points.

The feeling of sweetness: the seven experts mentioned above gave organoleptic evaluations in accordance with the following standards, and then calculated the average values of the ratings.

In cigarette products sold by the applicant company, the organoleptic evaluation of the sweetness sensation of the cigarette product, which caused the strongest sweetness sensation, was taken as 2.0 points (reference rating), and the organoleptic assessment of the sweetness sensation of the cigarette product, which caused the least sweetness sensation, was taken as 1 , 0 point (reference score). The evaluation of the cigarette manufactured in Example 1 relative to both reference ratings was determined in increments of 0.1 points.

The results obtained by averaging the ratings given by the seven test participants are shown as organoleptic ratings in the following Table 1.

menthol 1.28 1.29 1.36 1.44 1.49 1.55 1,60

The results presented in Table 1 are shown in the diagram in FIG. 6. 6, the segment of line a represents the results of the test for the sensation of sweetness, and the segment of line b represents the results of the test for the sensation of aroma of menthol.

According to the results presented above, it can be considered that the sensation of sweetness and the sensation of menthol aroma changed significantly as the number of puffs increased. Namely, it was believed that menthol, not interspersed with cyclodextrin, passes from the cotton thread to other parts (crushed tobacco, acetate fiber, etc.) during storage and is distributed in a cigarette in a state close to equilibrium. The delivery of menthol to the mainstream smoke of a cigarette is similar to the behavior with each puff of tar in the mainstream smoke of a cigarette. On the other hand, a sweet flavor (ethyl butyrate), interspersed in cyclodextrin, remains in the cotton thread during storage, and from the moment the mainstream smoke enters the filter during smoking, the sweet flavor is highly dependent on the amount of missed mainstream smoke; thus, the sensation of sweetness is strongly expressed in the initial stage of smoking, in comparison with menthol, which is not interspersed with cyclodextrin.

Example 2

In this example, dextrin powder containing levomenthol was prepared as follows.

Namely, 1 part by weight of sucrose and fatty acid ester (Kyoto Sugar Ester S-1170 manufactured by Mitsubishi-Kagaku Foods Corporation) was added to 59 parts by weight of purified water, and the mixture was stirred at 60 ° C. for 10 minutes. 40 parts by weight of dextrin (Sandec # 185 brand manufactured by Sanwa Starch Co., Ltd.) were added to the prepared solution, and the mixture was stirred for 30 minutes. During storage of the prepared solution at 50 ° C-60 ° C, 13.67 parts by weight of levomenthol were added and dissolved therein. The prepared solution was emulsified using a TK homogenizer mixer at a stirrer speed of 12,000 rpm for 10 minutes to prepare a spray solution. During storage of the spray solution at 50 ° C-60 ° C, it was sent to a spray dryer (model spray dryer MDL-050M manufactured by Fujisaki Electric Co., Ltd.) and spray dried at 180 ° C. Then received dextrin in the form of a powder containing levomenthol in an amount of 25 wt.%.

In addition, a device for manufacturing an aroma-generating element is provided, consisting of: packing yarn No. 20/16, according to English numbering, from bleached cotton; a fragrance tank; flavoring pump; devices for applying flavoring, etc .; for installation on a conventional filter manufacturing machine; a solution of levomenthol (concentration - 70%) in polypropylene or dextrin powder containing levomenthol dispersed in polypropylene glycol was introduced into the bath of the device for the manufacture of an aroma-releasing element. A device for manufacturing aroma-generating elements and a machine for manufacturing filters were driven, and the required long filter housing was made. The parameters of the acetate fiber tow, representing the filter housing, were as follows: fiber fineness -3.5 denier (3.89 dtex); total fineness of the tourniquet - 35,000 denier (3885 tex = 3.9 kteks); the cross-sectional shape of each fiber was Y-shaped. Used the same filter wrapper, which was used in Example 1. The circumference of the resulting long filter housing was 24.5 mm and a length of 100 mm. A cotton thread carrying flavor was introduced through the center of the long filter housing.

Two types of filter cigarettes samples A and B were made, as in Example 1, except for using the resulting long filter housing. Sample A of the filter cigarette contained levomenthol (additional amount was 11.5 g per filter length of 25 mm) which was not in dextrin; and sample B of the filter cigarette contained levomenthol (additional amount was 10.0 g per filter length of 25 mm), which was in the above dextrin powder. In images A and B of the cigarettes, the suction resistance of both filters was the same.

The obtained samples A and B of filter cigarettes were stored for one month, as in Example 1, and then the amount of menthol in the mainstream smoke was measured at each puff as follows.

Using a rotary automatic smoking unit with five smoking places, five samples of filter cigarettes with the same characteristics were inserted and the smoking process was reproduced, seven puffs were carried out according to the smoking conditions according to the ISO standard. With each puff, the components of the mainstream smoke stream were collected using a fiberglass filter set in advance; the components of the mainstream smoke of the cigarette were extracted using ethanol, and the amount of menthol was measured by gas chromatography. The same actions were performed twice with respect to samples of cigarettes having the same characteristics, and then the average value of the amount of menthol in the mainstream smoke was calculated. The average value was divided by the average value of the total menthol in seven puffs and expressed as a percentage, and the evaluation results were obtained. The results are presented in the following Table 2.

The results presented in Table 2 are shown in diagram form in FIG. 7. 7, the segment of line a represents the test results of sample A, and the segment of line b represents the test results of sample B.

When comparing the test results of samples A and B, it is seen that with an increase in the number of puffs, the amount of menthol in the mainstream smoke, i.e. the sensation of menthol is significantly different in different puffs. In sample B, since menthol is contained in dextrin (menthol is interspersed with dextrin), menthol is released from dextrin through water present in the mainstream smoke passing through the filter, and thus, the amount of menthol in the mainstream smoke increases significantly in the seventh puff . It was believed that this phenomenon is caused by the fact that there is an accumulation of water up to the sixth puff and a relative decrease in dilution of the main stream of smoke due to the fact that the burning part of the wrapper of a cigarette with air permeability approaches the filter, as a result of which the water temperature mainly increases a stream of smoke passing through the filter.

As shown in Examples 1 and 2, the aroma-generating behavior of aroma-generating elements bearing various aroma substances becomes apparent. According to the results of tests to determine aroma-releasing behavior, it was found that a cigarette equipped with a filter according to the invention containing a plurality of aroma-releasing elements carrying different aroma substances can emit different aromas during use when puffed.
