Hereinafter, aspects of the present invention will be described.

A cigarette filter according to one aspect of the present invention includes a filter main body, a fragrance release member including a fragrance carrier composed of at least one individual yarn, and a plurality of fragrance release components carried on the fragrance carrier. The aroma release member is incorporated in the filter body so as to extend along the central axis of the filter body. One scent-releasing component releases a different perfume scent than the other one or more scent-releasing components. The fragrance release behavior of one fragrance release component is different from the fragrance release behavior of one or more other fragrance release components. The fragrance releasing component is selected from the group consisting of pure fragrance, pure fragrance combined with cyclodextrin, and pure fragrance combined with dextrin.

The filter body into which the fragrance releasing member is incorporated includes, for example, cellulose acetate fiber tow and is usually cylindrical. The length of the filter body is usually 100 mm to 140 mm, and the diameter is usually 15 mm to 26 mm.

The fragrance release member includes a fragrance carrier made of at least one individual yarn and a plurality of fragrance release components carried on the fragrance carrier. The fragrance release member may comprise a fragrance carrier and a plurality of fragrance release components.

The yarn constituting the fragrance carrier can be composed of a single fiber (filament) or a bundle of a plurality of fibers (filament), and includes monofilament yarn and multifilament yarn. The multifilament yarn includes various processed yarns.

Thread material is not particularly limited. For example, the yarn can be made of a natural material such as cotton, wool or silk, or a synthetic material such as polypropylene, polyethylene or cellulose acetate.

The diameter of the yarn is usually 0.3 to 2.5 mm, preferably 0.7 mm to 1.5 mm. The length of the yarn is usually the same as the length of the filter body. The yarn typically extends along the central axis of the filter body over the entire length of the filter body, i.e., from the distal end to the proximal end of the filter body. The filter body is provided with a filter whose outer periphery is wound by a filter wrapper such as thin paper.

The aroma releasing component is selected from the group consisting of (i) pure fragrance, (ii) pure fragrance combined with cyclodextrin, and (iii) pure fragrance combined with dextrin. Pure fragrance is the fragrance itself.

The fragrance-releasing component consisting of pure fragrance can be supported on the yarn by dissolving it in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate, etc. and soaking the solution into the yarn. The fragrance-releasing component consisting of pure fragrance combined with cyclodextrin is suspended in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate, etc. It can be supported on. An emulsifier such as a sucrose fatty acid ester, a dispersant, and an antifoaming agent can be added to the suspension. A fragrance-releasing component consisting of pure fragrance combined with dextrin is suspended in polypropylene glycol, glycerin, ethanol, water, triglyceride, triacetin, triethyl citrate, etc. It can be carried on a yarn. An emulsifier such as a sucrose fatty acid ester, a dispersant, and an antifoaming agent can be added to the suspension. As an example, a fragrance-releasing component consisting of a pure fragrance combined with dextrin is optionally added to an aqueous solution of dextrin in which an emulsifier is dissolved, emulsified with a homomixer, sprayed using a spray dryer, and dried. By doing so, it can be obtained in the form of a fine powder of dextrin containing a fragrance.

One fragrance-releasing component releases a fragrance fragrance different from one or more other fragrance-releasing components. That is, the pure fragrance contained in one fragrance-releasing component is a fragrance that emits a different fragrance from the pure fragrance contained in one or more other fragrance-releasing components.

The fragrance release behavior of one fragrance release component is different from the fragrance release behavior of one or more other fragrance release components. The fragrance-releasing component made of pure fragrance releases the fragrance almost in proportion to the amount of tar in the cigarette mainstream smoke flowing into the filter when the cigarette is smoked. The aroma release component consisting of pure fragrance combined with cyclodextrin (in this case, the pure fragrance is included in cyclodextrin) is a specific smoke component in cigarette mainstream smoke that flows into the filter when smoking cigarette ( In particular, a fragrance is released by a rise in heat and a component having a vapor pressure at a level that is distributed between the liquid phase and the solid phase at room temperature. The fragrance-releasing component consisting of pure fragrance combined with dextrin (mixed with dextrin) releases fragrance mainly due to the moisture in the cigarette mainstream smoke flowing into the filter and the rise of heat.

In other words, the fragrance release component consisting of pure fragrance, the fragrance release component consisting of pure fragrance combined with cyclodextrin, and the fragrance release component consisting of pure fragrance combined with dextrin are each per puff when smoking cigarettes. The amount of perfume fragrance they release is different. Thus, cigarettes equipped with filters containing a plurality of different fragrance-releasing components can taste a blend of different amounts of different fragrances per puff, in addition to the flavor of the cigarette itself when smoked.

In order to manufacture a filter body in which an aroma releasing member is incorporated, for example, a method described in Japanese Patent Publication No. Sho 63-38187 can be applied. That is, for example, in a general cigarette filter manufacturing machine, immediately before the step of wrapping the opened cellulose acetate fiber bundle with a filter wrapper and forming it into a rod shape, the yarn is put at a predetermined position in the circumferential direction of the cellulose acetate fiber bundle. A guide and a mandrel to be guided are installed, and the yarn can be inserted into the cellulose acetate fiber bundle by passing the yarn through the guide and the mandrel. Needless to say, the thread is impregnated with the perfume-releasing component as described above before being inserted into the cellulose acetate fiber bundle.

In the first aspect of the present invention, the perfume carrier is composed of a plurality of individual yarns, and the plurality of aroma release components can be carried on different individual yarns. The cigarette filter according to the first aspect includes a filter body in which a plurality of fragrance release members each made of one or more individual yarns including an fragrance release component are incorporated, and the fragrance in one fragrance release member is the same. Is different from the fragrance in one or more other fragrance release members, and the fragrance release behavior of one fragrance release member is different from the fragrance release behavior of the other one or more fragrance release members. . In the first aspect, different yarns carrying different aroma releasing components can be colored differently from each other.

In the second aspect of the present invention, the fragrance carrier is composed of one or more individual yarns, and each individual yarn carries a plurality of aroma release components including different pure fragrances. In this case, the individual yarn is composed of a plurality of filaments, one filament is loaded with one fragrance release component, the other one or more filaments are loaded with another fragrance release component, and these filaments are twisted together. It is convenient to make a single thread. That is, in the second aspect, the fragrance release member is composed of one or more individual yarns carrying different fragrance release components.

The cigarette of the present invention includes the above-described filter of the present invention at one end of a cigarette rod. The cigarette rod is the same as the cigarette rod of a cigarette with a normal filter, and is composed of a rod of tobacco filler such as tobacco cut and cigarette wrapping paper that wraps the outer peripheral surface of the tobacco filler rod. The filter is connected to the cigarette rod by chip paper. The length of the cigarette rod is usually 40 mm to 70 mm, and the diameter may be the same as the diameter of the filter, or in order to make the connection with the filter by chip paper using glue more reliable. It may be slightly larger (up to 0.5 mm) than the diameter.

Next, aspects of the present invention will be described with reference to the drawings. Throughout the drawings, similar elements are denoted by the same reference numerals, and repeated description thereof is omitted.

FIG. 1 is an enlarged schematic perspective view showing an example of a filter according to the first aspect of the present invention. A filter 10 shown in FIG. 1 has a cylindrical filter body 110 made of tow of cellulose acetate fibers bound with a plasticizer such as triacetin. In the filter main body 110, a plurality of aroma release members extending in parallel with the central axis of the filter main body 110 are incorporated. The plurality of fragrance release members are composed of a plurality of individual yarns each carrying a fragrance release component including a pure fragrance. One of these fragrance release members includes a pure fragrance different from the pure fragrance contained in the other one or more fragrance release members. In FIG. 1, two

fragrance releasing members

121 and 122 are incorporated in the filter main body 110. For example, the fragrance release member 121 is made of cotton yarn 121a carrying a fragrance release component made of pure fragrance A, and the fragrance release member 122 is made of pure fragrance B combined with cyclodextrin or pure fragrance C combined with dextrin. The pure fragrance A is a fragrance different from the pure fragrance B and / or the pure fragrance C. The

cotton yarns

121a and 122a can be colored in different colors. The filter body 110 provides the filter 10 with the outer peripheral surface thereof being wrapped by a filter wrapper 130. The filter 10 defines a distal end surface 10a and a proximal end surface 10b. When the filter 10 is connected to the cigarette rod, the distal end surface 10a can come into contact with the proximal end surface of the cigarette rod. A filter area including the base end face 10b of the filter 10 is given by a smoker.

FIG. 2 is a schematic perspective view showing another example of the filter according to the first aspect of the present invention in an enlarged manner. The filter 20 shown in FIG. 2 has the same structure as the filter 10 of FIG. 1 except that the three

fragrance releasing members

221, 222, and 223 are incorporated in the filter body 110. For example, the fragrance release member 221 is made of a cotton yarn 221a carrying a fragrance release component made of pure fragrance A, and the fragrance release member 222 is made of a cotton yarn 222a carrying a fragrance release component made of pure fragrance B combined with a cyclodextrin. The fragrance release member 223 is made of a cotton thread 223a carrying a fragrance release component composed of pure fragrance C combined with dextrin. Here, for example, the pure fragrance A, the pure fragrance B, and the pure fragrance C are different fragrances, and thus emit different fragrances. The

cotton yarns

221a, 222a, and 223a can be colored in different colors. For example, the cotton yarn 221a can be colored blue, the cotton yarn 222a can be colored yellow, and the cotton yarn 223a can be colored pink.

FIG. 3 is an enlarged schematic diagram illustrating an example of a filter according to the second aspect of the present invention. The filter 30 shown in FIG. 3 is different from the

fragrance release members

121 and 122 except that the fragrance release member 310 composed of a single thread 310a carrying a plurality of fragrance release components is incorporated in the filter body 110. It has the same structure as the filter 10 shown in FIG. The yarn 310a carrying a plurality of fragrance components includes, for example, a cotton filament carrying a fragrance release component consisting of pure fragrance A, a cotton filament carrying a fragrance release component consisting of pure fragrance B combined with cyclodextrin, and a dextrin Cotton filaments carrying fragrance-releasing components comprising pure fragrance C combined with can be made by twisting together. Here, the pure fragrance A, the pure fragrance B, and the pure fragrance C may be different fragrances, and thus emit different fragrances. Two or more aroma release members 310 can be inserted through the filter body 110.

FIG. 4 is an enlarged schematic perspective view showing an example of a cigarette with a filter according to the present invention. The cigarette 40 with a filter shown in FIG. 4 includes a cigarette rod 410 having a distal end 410a and a proximal end 410b constituting an ignition end, and a filter 420 having a distal end 420a and a proximal end 420b. The cigarette rod 410 and the filter 420 are connected by a chip paper 430 with the base end 410b of the cigarette rod and the tip 420a of the filter abutting each other. The cigarette rod 410 is composed of the above-described tobacco filler rod 411 and cigarette wrapping paper 412 wrapping the outer peripheral surface of the tobacco filler rod 411. The filter 420 is configured by the filter of the present invention. For example, the filter 420 can be configured by the filter 10 shown in FIG. 1, the filter 20 shown in FIG. 2, or the filter 30 shown in FIG.

FIG. 5 shows the amount of perfume (delivery amount) delivered from the filter into the cigarette mainstream smoke passing through the filter 420 when the cigarette shown in FIG. 4 having the filter 20 shown in FIG. It is a graph for demonstrating the change for every puff.

For example, in the main body 110 of the filter 20, a fragrance release member (fragrance release member A) made of cotton yarn 221 a carrying a fragrance release component made of pure fragrance A, and a fragrance release component made of pure fragrance B combined with cyclodextrin. A fragrance release member (fragrance release member B) comprising a cotton yarn 222a carrying a fragrance, and a fragrance release member (fragrance release member C) comprising a cotton yarn 223a carrying a fragrance release component comprising a pure fragrance C combined with dextrin are incorporated. Here, the pure fragrance A, the pure fragrance B, and the pure fragrance C are different from each other. The amount of the fragrance delivered from the fragrance release member A into the cigarette mainstream smoke gradually increases almost linearly for each puff (curve a). The amount of the fragrance delivered from the fragrance release member B into the mainstream smoke of the cigarette is larger than the case of the fragrance release member A from the beginning to the middle of the puff, but gradually decreases thereafter, and the fragrance is delivered in the latter stage of the puff. The amount is less than in the case of the fragrance release member A (curve b). The amount of the fragrance delivered from the fragrance releasing member C into the mainstream smoke of the cigarette is very small from the early stage to the middle stage of the puff, but increases rapidly in the later stage of the puff, and the amount of fragrance delivered from the fragrance releasing members A and B (Curve c). Thus, when a smoker smokes a cigarette with a filter according to the present invention, in addition to the flavor of the cigarette itself, the smoker can taste a blend of different amounts of different flavors for each puff.

Hereinafter, although an example explains the present invention, the present invention is not limited to the following example.

Example 1
In this example, a filter having the structure shown in FIG. 1 was produced, and this was connected to a cigarette rod to produce a cigarette with a filter, which was subjected to sensory evaluation.

Specifically, following the method described in Japanese Examined Patent Publication No. Sho 63-38187, a 20/8 bleached cotton yarn cheese, a perfume tank, a perfume feed pump, a perfume application on a normal filter manufacturing machine with a British count display. 2 sets of fragrance release member manufacturing equipment consisting of a scent, etc., L-menthol polypropylene solution (concentration 70%) is placed in the fragrance tank of one fragrance release member manufacture apparatus, and the fragrance of the other fragrance release member manufacture apparatus Α-cyclodextrin inclusion ethyl butyrate (sweet flavor) (concentration 50%) dispersed in polypropylene glycol was placed in the tank. Both fragrance | flavor discharge | release member manufacturing apparatuses and the filter manufacturing machine were driven, and the desired filter elongate body was produced. The specifications of the cellulose acetate fiber tow constituting the filter body were a single fineness of 2.5 denier and a total fineness of 35000 denier, and the cross-sectional shape of each fiber was Y-shaped. The filter wrapper had an air permeability of 10,000 coresta units (CU), a basis weight of 24.0 g / m ² and a width of 26.5 mm. The obtained long filter body had a circumference of 24.5 mm and a length of 100 mm.

The cigarette with a filter was produced with a normal cigarette hoist using this long filter body and the cigarette filler, cigarette wrapping paper, and chip paper necessary for producing a cigarette rod of a commercial cigarette product (Salem Alaska). At that time, the long filter body was divided into four pieces, and a length of 25 mm was abutted with the cigarette rod per cigarette.

The specifications of the cigarette rod were a circumferential length of 24.5 mm and a length of 84 mm.

20 Twenty produced cigarettes with a filter were put in a normal cigarette package and sealed. The cigarette package was stored in an environment at a temperature of 22 ° C. and a relative humidity of 60% for 1 month. After storage, the cigarette with a filter was taken out from the package, smoked by seven panelists, and sensory evaluation of the flavor was performed.

Sensory evaluation was given to each cigarette from the 1st puff to the 7th puff, and the following flavor evaluation items were scored for each puff.

<Savory evaluation items>
Sensation of menthol: Received expert training in cigarette savory evaluation, and scored sensory scores based on the following criteria by seven professional evaluators from the applicant company in charge of savory evaluation and savory development. Was calculated.

Among the cigarette products sold by the applicant company, the sensory score of the menthol feeling of the cigarette product showing the strongest menthol feeling is set to 2.0 (reference point), and the sensory score of the menthol feeling of the cigarette product without the menthol feeling Was set at 1.0 point (reference point), and the cigarette produced in Example 1 was scored in 0.1 point increments as compared to both reference points.

Sense of sweetness: The above seven expert evaluators assigned sensory scores according to the following criteria and calculated the average value.

Among the cigarette products sold by the applicant company, the sensory score of the sweetness of the cigarette product showing the strongest sweetness is set to 2.0 (reference point), and the sweetness of the cigarette product with the weakest sweetness is set. The sensory score of the feeling was set at 1.0 (reference point), and the cigarette produced in Example 1 was scored in 0.1 point increments as compared to both reference points.

The results of averaging the evaluation results of these seven people are shown in Table 1 below as sensory scores.

Also, the results shown in Table 1 are shown as a graph in FIG. In FIG. 6, line segment a indicates the result of sweetness, and line segment b indicates the result of menthol feeling.

As can be seen from the above results, the sweetness and menthol feeling changed greatly as the puff progressed. That is, it is considered that menthol not included in cyclodextrin migrated from cotton yarn to other parts (cigarette carved, cellulose acetate fiber, etc.) during the storage, and was distributed in an almost equilibrium state in the cigarette. The delivery of menthol into cigarette mainstream smoke is similar to the tar-puff behavior of cigarette mainstream smoke. On the other hand, the sweet flavor (ethyl butyrate) encapsulated in cyclodextrin remains in the cotton yarn during the above storage and is released depending on the amount of mainstream smoke that passes through the mainstream smoke through the filter due to smoking. Therefore, compared with menthol not included in cyclodextrin, the sweetness is strongly expressed in the first half of smoke absorption.

Example 2
In this example, L-menthol-containing dextrin powder was produced as follows.
That is, 1 part by weight of sucrose fatty acid ester (“Ryoto Sugar Ester S-1170” manufactured by Mitsubishi Chemical Foods Co., Ltd.) as an emulsifier was added to 59 parts by weight of purified water and stirred at 60 ° C. for 10 minutes. To the obtained solution, 40 parts by weight of dextrin (“Sandek # 185” manufactured by Sanwa Starch Co., Ltd.) was added and stirred for 30 minutes. While maintaining the obtained solution at 50 to 60 ° C., 13.67 parts by weight of L-menthol was added and dissolved. The obtained solution was emulsified with a TK homomixer at 12000 rpm for 10 minutes to obtain a spray solution. While maintaining this spray solution at 50 to 60 ° C., it was sent to a spray dryer (“Spray Dryer MDL-050M” manufactured by Fujisaki Electric Co., Ltd.) and spray-dried at 180 ° C. Thus, dextrin powder containing 25% by weight of L-menthol Got.

Next, a perfume discharge member manufacturing apparatus comprising a 20/16 bleached cotton yarn cheese, a perfume tank, a perfume feed pump, a perfume applicator and the like is attached to a normal filter manufacturing machine, and the perfume tank. The L-menthol-containing polypropylene solution (concentration 70%) or the above-mentioned L-menthol-containing dextrin powder dispersed in polypropylene glycol was placed in The fragrance | flavor discharge | release member manufacturing apparatus and the filter manufacturing machine were driven, and the desired filter elongate body was produced. The specifications of the cellulose acetate fiber tow constituting the filter body were a single fineness of 3.5 denier and a total fineness of 35000 denier, and the cross-sectional shape of each fiber was Y-shaped. The filter wrapper was the same as that used in Example 1. The obtained long filter body had a circumference of 24.5 mm and a length of 100 mm. The cotton yarn carrying the fragrance was inserted into the center of the long filter body.

Two types of cigarette samples A and B with a filter were prepared in the same manner as in Example 1 except that the obtained long filter body was used. The cigarette sample A with a filter contains L-menthol not added to the dextrin (addition amount: 11.5 g per 25 mm filter length), and the cigarette sample B with the filter contains the L-menthol contained in the dextrin powder. -It contained menthol (addition amount: 10.0 g per 25 mm filter length). In filter cigarette samples A and B, the ventilation resistance of both filters was the same.

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

Five cigarette samples with filters of the same specification were set using a 5-spindle rotary type automatic smoker, and smoked up to 7 puffs under ISO standard smoking conditions. For each puff, cigarette mainstream smoke components were collected on a glass fiber filter installed in advance, extracted with ethanol, and the amount of menthol was measured by gas chromatography. Perform the same operation twice for the cigarette sample of the same specification, calculate the average value of the menthol amount in the mainstream smoke for each puff, and divide the average value by the average value of the menthol amount of the total of 7 puffs. It was expressed as an evaluation result. The results are shown in Table 2 below.

Also, the results shown in Table 2 are shown as a graph in FIG. In FIG. 7, the line segment a indicates the result for the sample A, and the line segment b indicates the result for the sample B.

As can be seen by comparing the results for Sample A and Sample B, as the puff progresses, the amount of menthol in the mainstream smoke, that is, the strength of the menthol feeling, differs greatly between the two. In Sample B, since menthol is contained (supported) in dextrin, menthol is released from the dextrin by moisture in the mainstream smoke passing through the filter, so that the amount of menthol in the mainstream smoke increases significantly at the seventh puff. is doing. This phenomenon is caused by the accumulation of water up to 6 puffs and the relative reduction in dilution of mainstream smoke by cigarette wrapping paper that has air permeability due to the proximity of the combustion section to the filter. The reason is that the temperature rises.

As shown in Examples 1 and 2, the fragrance release behavior from the fragrance release member carrying various fragrances was clarified. From the results of these fragrance release behaviors, it is clear that cigarettes equipped with a filter incorporating a plurality of fragrance release members each carrying different fragrances according to the present invention make it possible to taste different fragrances for each puff.
