Triacetin may be applied as the plasticizer, and triacetin may be included in 5 to 15% of the total weight of the filter unit 110, but the type and content of the plasticizer is not limited thereto, and may be appropriately adjusted as necessary. have.

Although the filter unit 110 of the present embodiment is illustrated as a mono filter including a single filter, it is not limited thereto. For example, it is natural that the filter unit 110 may be provided as a dual filter or a triple filter having two acetate filters in order to increase filter efficiency.

Furthermore, although not shown, a capsule (not shown) may be included in the filter unit 110 . The capsule may have a structure in which the liquid containing the fragrance is wrapped with a film, for example, the capsule may have a spherical or cylindrical shape. The diameter of the capsule may be approximately 2.6 mm to 3.5 mm, but is not limited thereto, and the diameter of the capsule may vary according to the specification of the smoking article 100 .

The material forming the capsule film may be a natural material, starch and/or a gelling agent. For example, in the case of a film made of a natural material, it may be composed of agar, pectin, sodium alginate and glycerin. Gellan gum or gelatin may be used as the gelling agent. Further, a gelling aid may be further used as a material for forming the film of the capsule. Here, as the gelling aid, for example, calcium chloride can be used.

The content of the capsule may include flavorings such as menthol and essential oils of plants, but is not limited thereto.

The filter unit 110 may be wrapped by a filter wrapper 110a. In some embodiments, the filter wrapper 110a may be made of a wrapper having oil resistance. The filter wrapper 110a may be made of oil resistant paper in order to prevent the capsule content discharged to the outside of the capsule from passing through the filter wrapper 110a as the capsule included in the filter unit 110 is crushed by a smoker. In some embodiments, an aluminum foil may be further included on the inner surface of the filter wrapper 110a.

The above-described filter unit 110 is disposed downstream of the smoking material unit 120, and serves as a filter through which the aerosol material generated in the smoking material unit 120 passes just before inhalation by the user.

The smoking material portion 120 may contain an aerosol-generating material. For example, the smoking material portion 120 may include tobacco strands. The smoking material unit 120 may have an elongated rod shape and may have various lengths, circumferences, and diameters.

In addition, the wetting agent may include glycerin or propylene glycol, and the like.

In some embodiments, the smoking material unit 120 pulverizes the tobacco raw material, mixes a solvent and various additives to form a slurry, then dries it to form a sheet, and then processes the sheet into pieces such as rods. formed reconstituted tobacco material. For example, smoking material portion 120 includes a plurality of strands of tobacco material, one strand being approximately 10 mm to 14 mm long (eg, 12 mm) and approximately 0.8 mm to 1.2 mm wide (eg, For example, 1 mm) and a thickness of approximately 0.08 mm to 0.12 mm (eg, 0.1 mm), but is not limited thereto.

The density of the tobacco material filled in the smoking material unit 120 is increased by allowing the smoking material unit 120 to include a plurality of strand materials processed in the form of a wide tobacco sheet, thereby increasing the amount of aerosol generated, and smoking. Smoking characteristics of the material part 120 may be improved.

The smoking material part 120 may be wrapped by the smoking material wrapper 120a.

In some embodiments, the smoking material wrapper 120a may include a filler, thereby increasing the opacity or imparting porosity of the smoking material wrapper 120a, and improving the smoothness and retrospective integrity of the cigarette paper. It can be improved, and the whiteness of the cigarette paper can be increased. Materials such as calcium carbonate, titanium dioxide, and magnesium oxide may be used as the filler, but is not limited thereto.

Also, although not shown, the smoking material wrapper 120a may have a double wrapper structure. Specifically, the smoking material wrapper 120a is an inner wrapper (not shown) that is in contact with the smoking material unit 120 and surrounds the smoking material unit 120 , and an outer wrapper that is in contact with the inner wrapper and wraps the outside of the inner wrapper. (outer wrapper) may be included.

The filter unit 110 packaged by the filter wrapper 110a and the smoking material unit 120 packaged by the smoking material wrapper 120a may be combined and packaged by the tip paper 130 . That is, the tip paper 130 may be surrounded by at least a portion of the smoking material wrapper 120a (eg, a downstream partial region) and the outer circumference of the filter wrapper 110a. In other words, at least a portion of the smoking material unit 120 and the filter unit 110 may be further wrapped by the tip paper 130 and physically coupled thereto.

In some embodiments, the tip paper 130 may be made of non-porous wrapping paper that is not oil-resistant, but is not limited thereto.

The tip paper 130 may be coated with a sweetener such as sucralose or citric acid. In addition, a predetermined material may be internally attached to the tip paper 130 . An example of the predetermined material may be silicon, but is not limited thereto. For example, silicon has characteristics such as heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency against water, or electrical insulation. However, even if it is not silicone, if it is a material having the above-described properties, it may be applied or coated on the tip paper 130 without limitation.

The tip paper 130 may prevent the filter unit 110 from being burned. For example, when the smoking material unit 120 is combusted to a portion adjacent to the filter unit 110 , there is a possibility that the smoking material unit 120 is combusted to the filter unit 110 . Even in this case, since the tip paper 130 contains a non-combustible material, it is possible to prevent the filter unit 110 from burning.

On the other hand, when the smoking material wrapper 120a is manufactured, a filler is included in the smoking material wrapper 120a by various compositions and methods as described above for reducing the cigarette smell caused by smoke generated by smoking, or double Various attempts have been made, such as forming a wrapper structure or applying a water-soluble fragrance carrier enclosing a fragrance. However, aside from the sidestream smoke reduction effect of the various attempts, the part that the smoker's finger directly touches during smoking is the tip paper 130, not the smoking material wrapper 120a. There is a need for a finger cigarette odor reduction technology that can be directly applied to the tip paper 130 rather than the material wrapper 120a.

Accordingly, the tip paper 130 of the present invention includes a fragrance material for masking the cigarette smell, and a fragrance carrier composed of a carrier material for enclosing the fragrance material. The fragrance carrier may be included in the tip paper for smoking articles through a tip paper fragrance carrier printing process using a fragrance carrier ink comprising ethanol, the fragrance material, and the carrier material.

The fragrance carrier ink may be prepared by sequentially adding and stirring a carrier material, a fragrance material, and a binder to ethanol. Specifically, the fragrance carrier ink is prepared by i) adding a carrier material to ethanol and stirring for approximately 30 to 60 minutes; ii) adding the perfume material to the ethanol solution to which the carrier material is added and stirring for approximately 15 to 45 minutes; and iii) adding a binder to the ethanol solution to which the carrier material and the fragrance material are added and stirring for approximately 15 to 45 minutes.

When the fragrance carrier ink includes microcapsules to be described later, after step iii), iv) adding the microcapsules to the ethanol solution to which the carrier material, the fragrance material and the binder are added and stirring for about 15 to 45 minutes may be further included.

The fragrance carrier printing process may be performed by mixing the fragrance carrier with the ink used in the OPV (Over print varnish) process performed on the tip paper, but preferably, in order to maximize the amount of fragrance transferred to the tip paper, the OPV After the process, it may be performed as a printing process separate from the OPV process.

In some embodiments, the fragrance carrier ink may further include a binder and/or microcapsules, and details of the binder and microcapsules will be described later.

The carrier material in the present invention is characterized in that it is not soluble in water, isopropyl alcohol, etc., but is soluble in ethanol. For example, the carrier material may be 2-hydroxypropyl-β-cyclodextrin.

This is a method of applying a water-soluble fragrance carrier material (for example, beta-cyclodextrin) enclosing a fragrance material to the smoking material wrapper 120a described above. This is because it is practically impossible to apply as it is to (130). Specifically, when the water-soluble fragrance carrier method is applied to the tip paper 130, water should be used as the ink solvent, and in this case, the surface energy of the ink is increased to about 70 mN/m to 75 mN/m, so that the tip paper 130 is printed. Thereafter, difficulties arise in the drying process, and problems such as contamination of the tip paper and ink tearing due to weakening of the bonding force between the printed ink and the tip paper may occur. Furthermore, when the drying temperature is increased or the drying time is increased for drying the ink having the increased surface energy as described above, the curl of the tip paper is increased. On the other hand, when the fragrance material is printed on the tip paper without applying the above carrier method, the fragrance material is lost to the outside of the smoking article during the storage period of the tip paper due to the characteristics of the tip paper disposed on the outermost part of the smoking article. , It causes discoloration of the tip paper depending on storage conditions such as light/humidity.

On the other hand, as in the present invention, when the carrier material applied to the tip paper is applied as a polymer material such as 2-hydroxypropyl-beta-cyclodextrin, which contains a hydrophobic fragrance material and is soluble in ethanol, ink Ethanol can be used as a solvent, so ink having a surface energy of about 20 mN/m to 50 mN/m can be used. Accordingly, the printing and drying process of tip paper can be applied, and only the workability of manufacturing smoking articles There is no discoloration issue, so storage stability can also be secured.

On the other hand, the fragrance material encapsulated in the carrier material is expressed to the outside of the tip paper 130 (that is, the outside of the smoking article 100) in response to moisture, saliva, or friction. The fragrance material is transferred to the smoker's finger holding the tip paper portion, so that it can perform the role of masking the cigarette smell of the finger.

Furthermore, the perfume material is entrapped in the carrier material before moisture or saliva (eg, saliva) is transferred to the tip paper or friction (eg, the smoker grips or rubs the tip paper) is transferred to the tip paper. Since it is not expressed, it is possible to solve the problem of loss of flavor with the lapse of storage period or the occurrence of unnecessary flavor while the smoker is simply storing the smoking material.

The perfume material included in the carrier material may include at least one of vanillin and ethyl vanillin.

On the other hand, as will be described later with reference to Tables 7 to 8, the combined weight ratio of the vanillin and ethyl vanillin in consideration of the discoloration issue of the tip paper may be 0.1% or more and 50% or less based on the total weight of the fragrance material. Preferably, the weight ratio of vanillin to the total weight of the perfume material may be 0.1% or more and 30% or less, and the weight ratio of ethylvanillin may be 0.1% or more and 20% or less. More preferably, the weight ratio of the vanillin to the total weight of the perfume material may be about 15% to 25%, and the weight ratio of the ethylvanillin may be about 5% to 15%.

The perfume material may include various components other than the vanillin and ethyl vanillin, and Table 1 shows the components of the perfume material confirmed to maximize the effect of reducing the odor of finger tobacco.

In some embodiments, the perfume material may have a composition ratio of rosemary oil (ROSEMARY OIL), vanillin, fermented alcohol, LAVANDIN oil (LAVANDIN OIL), ethyl vanillin, and eucalyptol (EUCALYPTOL) in order. Contained in the perfume material The weight ratio of the vanillin and the eucalyptone prepared is about 2.5:1 to 3.5:1 (preferably, about 3:1), and the weight ratio of the ethylvanillin and the lavandin oil contained in the perfume material is about 0.5: 1 to 1.5:1 (preferably, about 1:1), but is not limited thereto.

On the other hand, if the fragrance carrier ink contains more fragrance material than necessary, there may be a problem that the fragrance is transferred to other tip papers to which the fragrance should not be applied other than the tip paper of the present invention during the mass production process, and storage after the preparation of the tip paper A problem of discoloration may also occur.

In order to solve this problem, the weight ratio of the fragrance material to the total weight of the fragrance carrier ink may be about 0.1% or more and 3% or less, and the weight ratio of the carrier material may be about 0.1% or more and 30% or less. Preferably, the weight ratio of the fragrance material to the total weight of the fragrance carrier ink is about 0.1% or more and 1.5% or less, and the weight ratio of the carrier material may be about 0.1% or more and 15% or less. More preferably, the weight ratio of the fragrance material to the total weight of the fragrance carrier ink may be about 0.4% to 1.3%, and the weight ratio of the carrier material may be about 5% to 10%.

The binder that may be included in the fragrance carrier ink may be an acryl and starch-based polymer soluble in ethanol. By including a binder that may be included in the fragrance carrier ink, it is possible to increase the residual amount of the tip paper of the fragrance material encapsulated in the fragrance carrier. That is, through the binder, it is possible to better preserve the fragrance material or the fragrance carrier, which may be lost during the storage period after the manufacture of the smoking article, in the tip paper.

On the other hand, in order for the binder to perform the above-mentioned role of preserving the perfume material and at the same time to secure printing workability, an appropriate viscosity of the binder is required. For this, the binder has a molecular weight of about 1,000 to 30,000 and a glass transition temperature. It may be a polymer material having a temperature of approximately 50°C to 100°C. Preferably, the binder may be a polymer material having a molecular weight of approximately 3,000 to 20,000 and a glass transition temperature of approximately 60°C to 90°C. This is because, if the viscosity of the binder is too low, the ink flows, and if the viscosity is too high, the ink becomes stiff and workability is deteriorated, and the inherent performance of the binder may also decrease.

In addition, as will be described later with reference to Table 4, as the binder application amount increases, the fragrance retention tends to increase, but if the binder application amount is too large, the tip paper curl increases, which may cause difficulties in manufacturing a smoking article.

In order to solve this difficulty, the weight ratio of the binder to the total weight of the flavor carrier ink may be about 0.1% or more and 15% or less. Preferably, the weight ratio of the binder to the total weight of the fragrance carrier ink may be approximately 5% to 10%.

The microcapsule, which may be included in the fragrance carrier ink, may include polyvinyl alcohol (PVA), a fragrance, and a crosslinking agent. Specifically, a core of the microcapsule is an ethanol-based fragrance, a shell is polyvinyl alcohol, and sodium sulfate (Na ₂ SO ₄ ) may be used as a crosslinking agent. The fragrance may be an ethanol-based fragrance. The microcapsules may have a diameter of about 1.5um to 5.0um.

In some embodiments, the perfume may have the same composition as the perfume material included in the above-described perfume carrier material.

In some embodiments, the weight ratio of the polyvinyl alcohol and the fragrance in the microcapsule may be about 1:3 to 1:7. Preferably, the weight ratio of the polyvinyl alcohol and the fragrance in the microcapsule may be about 1:5. For example, the microcapsules may be prepared by stirring about 5% of polyvinyl alcohol, about 25% of a fragrance, and about 1.5% of a crosslinking agent.

In some embodiments, the weight ratio of the microcapsule to the total weight of the flavor carrier ink may be about 0.1% or more and 25% or less, preferably about 5% to 20%. Through this, it is possible to solve the problem of overexpression before smoking due to breakage of the microcapsule and/or the problem that the tip paper surface is contaminated by the capsule shell and becomes rough, which may occur as the microcapsule is contained in excess.

In some embodiments, the weight ratio of the binder to the total weight of the flavor carrier ink may be about 5% to 10%, and the weight ratio of the microcapsules may be about 5% to 20%. Preferably, the weight ratio of each of the binder and the microcapsule relative to the total weight of the flavor carrier ink may be approximately 5%.

The microcapsules are prepared by i) stirring the ethanol-based fragrance and polyvinyl alcohol at room temperature for about 15 to 45 minutes; ii) adding a crosslinking agent to the solution in which the ethanol-based fragrance and polyvinyl alcohol are stirred at a level of about 30% compared to polyvinyl alcohol, and stirring at a temperature of about 60° C. or higher and 100° C. or less, for about 5 to 10 hours; iii) an ethanol-based fragrance, polyvinyl alcohol, and a crosslinking agent may be prepared by cooling a stirred solution at room temperature for about 30 minutes to 2 hours.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through Examples and Comparative Examples. However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

After the fragrance carrier printing process of the present invention was performed on the tip paper material of Comparative Example 1 on which the OPV printing process and the drying process were completed, the drying process was performed at a drying speed of about 150 m/min. In the fragrance carrier printing process, ethanol is used as a solvent, and fragrance carrier ink containing about 1.25% of the fragrance material of Table 1, about 9% of 2-hydroxypropyl-β-cyclodextrin, and about 5% of the binder was used.

Experimental Example 1: Evaluation of drying and curl characteristics after printing of tip paper

In order to check the drying and curl characteristics after printing of the tip paper prepared according to the embodiment of the present invention, the surface energy of the ink applied to the printing by Examples and Comparative Examples, the degree of dissolution of the fragrance carrier, the degree of drying of the ink and the tip paper Curls were analyzed, and the results are shown in Table 2.

As shown in Table 2, in all of Example 1, Comparative Examples 2 and 3, the degree of dissolution of the flavor carrier was all good. However, for the tip paper in Comparative Example 2 to which the water-soluble flavor carrier printing was applied, it was confirmed that the ink was incompletely dried after the printing and drying process, which is because water is used as the ink solvent when printing the water-soluble flavor carrier, so the surface energy of the ink is 72.4 mN It is judged that it is due to having a high value of /m. In Comparative Example 3, in which the drying speed was lowered to 10 m/min for complete drying of the ink using water as a solvent, a good ink drying degree was exhibited, but a high value of about 12 mm of the tip paper curl occurred, and it was confirmed that the tip paper in Comparative Example 3 could not be applied to the mass production process of cigarettes.

In contrast, the tip paper of Example 1 to which ethanol is used as the ink solvent and to which the flavor carrier and binder is applied has a good ink drying degree, and at the same time, the tip paper curl is significant compared to the value of Comparative Example 1 to which the flavor carrier printing process is not applied. There was no difference, and it was confirmed that the tip paper in Example 1 was not at all unreasonable in the application of the cigarette mass production process.

Example 2

For the example, the medium and the filter part were separated by removing the tip paper of the cigarette prepared for the test. A smoking article in which the separated medium and filter parts are combined with tip paper having a porosity of about 100 CU, manufactured by applying the OPV process and the fragrance carrier printing process using the ethanol-based fragrance carrier ink containing 0.4% of the fragrance material. prepared.

Example 3

A smoking article was prepared in the same manner as in Example 2, except that 0.7% of the fragrance material was contained in the ethanol-based fragrance carrier ink.

Example 4

A smoking article was prepared in the same manner as in Example 2, except that 1.25% of the fragrance material was contained in the ethanol-based fragrance carrier ink.

Example 5

A smoking article was prepared in the same manner as in Example 2, except that 1.5% of the fragrance material was contained in the ethanol-based fragrance carrier ink.

Comparative Example 4

Unlike Examples 2 to 5, a smoking article was prepared in the same manner as in Example 2, except that the fragrance printing process was performed by stirring the ink without supporting the fragrance material.

Experimental Example 2: Evaluation of finger odor reduction index material of tip paper - without binder

In order to measure the effect of reducing finger odor when smoking cigarettes according to Examples and Comparative Examples, changes in the vanillin and ethylvanillin content of the smoke collected from the tip paper were analyzed, and are shown in Table 3.

Smoking articles according to Examples and Comparative Examples were all smoked 2 weeks after manufacture, and smoking conditions were set as a puff volume of 55 ml, a puff time of 2 seconds, a puff cycle of 20 seconds, and the number of puffs 12 times, and vanillin and ethyl Vanillin content analysis was performed by GC (gas chromatography) analysis of smoke collected by wrapping a CFP (Cambridge filter pad) in the tip paper 130 .

As shown in Table 3, vanillin and ethylvanillin components were detected in all examples, and it was confirmed that the detected vanillin and enylvanillin components could perform a role of masking odors by contacting the fingers. , Looking at the analysis results in Example 4 and Comparative Example 4, even if the weight of the fragrance material in the ink is the same, the fragrance material is contained in the carrier material than in the case where the fragrance printing is performed without supporting the fragrance material (Comparative Example 4). It can be confirmed that more vanillin and ethylvanillin components were detected in the case where the flavor carrier printing was performed by contacting (Example 4).

Furthermore, looking at the analysis results in Examples 2 to 5, as the weight of the fragrance material in the fragrance carrier ink increased, the amount of vanillin and ethyl vanillin components expressed in the tip paper tended to increase. However, in the case of Example 5, in which the weight of the supported perfume material is 1.5%, there is a problem in that the fragrance is transferred to other tip papers other than the tip paper of the present invention during the mass production process, to which the fragrance should not be applied. In Example 4 in which the weight of the cigarette was 1.25%, it was confirmed that the effect of reducing finger odor due to smoking was excellent and at the same time it was within the mass production possible range of the cigarette.

Example 6

A smoking article was prepared in the same manner as in Example 4 described with reference to Table 3, except that 1.0% of the binder was contained in the ethanol-based fragrance carrier ink. As the binder, a polymer material having a molecular weight of about 18,000 and a glass transition temperature of about 80°C was used.

As shown in Table 4, as the weight of the binder in the fragrance carrier ink increased, the amount of vanillin and ethyl vanillin components expressed in the tip paper tended to increase. However, in the case of Example 9, in which the binder weight is 15%, a problem of excessively increasing tip paper curl occurs, and when the weight of the binder is 5% to 10%, the effect of reducing finger odor due to smoking is excellent It was confirmed that the tip paper curl issue can also be resolved.

Example 10

A smoking article was prepared in the same manner as in Example 8 described with reference to Table 4, except that 5.0% of microcapsules were contained in the ethanol-based fragrance carrier ink. As for the microcapsules, microcapsules having a diameter of approximately 1.5 μm to 5.0 μm were used, in which the core was an ethanol-based fragrance, the shell was made of polyvinyl alcohol, and sodium sulfate was used as a crosslinking agent.

Example 11

A smoking article was prepared in the same manner as in Example 10, except that 10.0% of the binder was contained in the ethanol-based fragrance carrier ink.

Tip paper surface contamination

As shown in Table 5, as the weight of the microcapsules in the fragrance carrier ink increased, the amount of vanillin and ethylvanillin components expressed in the tip paper tended to increase. However, in the case of Example 13 in which the weight of the microcapsule is 25%, the outward strength generated in the cigarette storage state before smoking excessively increases, and the tip paper surface contamination due to the breakage of the microcapsule occurs, so that the weight of the microcapsule is 10% to When it reached 20%, it was confirmed that the effect of reducing finger odor due to smoking was excellent, and at the same time, the outward strength and tip paper surface contamination problems could be resolved.

Experimental Example 5: Evaluation of print workability/following process workability of tip paper

The physical properties of the tip paper were analyzed in order to confirm the print workability of the tip paper prepared according to the embodiments of the present invention and the workability characteristics of the subsequent process for manufacturing a cigarette after printing, and the results are shown in Table 6 . For the analysis of the physical properties of the tip paper in Experimental Example 5, the tip paper prior to being assembled into each smoking article in Examples 8 and 10 to 12 was evaluated.

As shown in Table 6, in both Examples 8 and 10 to 12, the tip paper printing workability was good, and the paper was dried while the ink was less dried and the adhesion problem between the front and back surfaces of the tip paper that could occur due to transfer to the back side It can be seen that the slip property was good without the problem that the surface of the tip paper was slippery due to the slippery surface or the surface was too rough, and the curl of the tip paper was also within the appropriate numerical range. Accordingly, it was confirmed that there was no problem in the printing workability of the fragrance carrier using the fragrance carrier ink including the fragrance material, the binder, and the microcapsule within the scope of the above embodiments.

Example 14

For the example, the medium and the filter part were separated by removing the tip paper of the cigarette prepared for the test. A smoking article in which the separated medium and filter parts are combined with tip paper having a porosity of about 100 CU, manufactured by applying the OPV process and the fragrance carrier printing process using the ethanol-based fragrance carrier ink containing 1.25% of the fragrance material. prepared. Here, 5% of vanillin and 10% of ethylvanillin were contained in the perfume material.

Example 17

A smoking article was prepared in the same manner as in Example 14, except that 30% of vanillin was contained in the fragrance material.

Example 18

A smoking article was prepared in the same manner as in Example 14, except that 40% of vanillin was contained in the fragrance material.

Comparative Example 5

Unlike Examples 13 to 17, a smoking article was prepared in the same manner as in Example 15, except that the fragrance printing process was performed by stirring the ink without supporting the fragrance material.

Experimental Example 6: Evaluation of color stability according to changes in vanillin content in fragrance materials

In order to evaluate the color stability of tip paper according to the change in the vanillin content in the flavoring material, the degree of color change of the cigarette immediately after manufacture and the cigarette 2 months after manufacture is quantified as the color difference (ΔE) in the CIELAB color space. 7 is shown. Cigarettes were stored for 2 months at a temperature of about 40° C. and a relative humidity of about 60%.

Looking at the analysis results in Examples 13 to 17, it can be seen that the degree of discoloration of the tip paper increases as the weight of vanillin in the fragrance material increases (the weight of ethyl vanillin is fixed at 10%). In particular, it can be seen that in Examples 16 and 17 in which the weight of vanillin is 30% or more, the degree of discoloration rapidly increased to a value that the discoloration can be observed with the naked eye, and in Examples 13 to 15 in which the weight of vanillin is 5% to 20%, It can be seen that the degree of discoloration of the tip paper is insignificant. In addition, looking at the analysis results in Example 15 and Comparative Example 5, even if the weight of vanillin and ethyl vanillin in the fragrance material is the same, fragrance printing is performed without supporting the fragrance material. It was confirmed that the degree of discoloration was smaller in the case where the fragrance carrier printing was performed (Example 15) by enclosing the fragrance material in the carrier material than in the case where it was performed (Comparative Example 5).

In particular, it can be seen that in Examples 19 to 21 in which the weight of ethyl vanillin is 20% or more, the degree of discoloration rapidly increased to a value that the discoloration can be observed with the naked eye, and Examples 15 and 15 in which the weight of ethyl vanillin is 5% to 10% 18, it can be seen that the degree of discoloration of the tip paper is insignificant.

Experimental Example 8: Smoking sensory evaluation of tip paper applied with fragrance carrier

In order to confirm the sensory characteristics of the tip paper applied with the fragrance carrier of the present invention, the outward appearance strength, the tobacco taste strength, the cigarette smell strength of the fingers after smoking, and the finger odor strength after smoking the smoking articles according to Example 1, Comparative Example 1 and Comparative Example 4 Sensory evaluation was performed on the residual fragrance intensity and the satisfaction of the fragrance remaining on the finger.

Sensory characteristic evaluation was conducted for 20 evaluation panel members using the smoking articles of Example 1, Comparative Example 1, and Comparative Example 4, and a total of 8 points was the standard.

2 is a smoking sensory evaluation result for smoking articles prepared according to Example 1, Comparative Example 1 and Comparative Example 4 and stored at room temperature for 2 weeks, FIG. 3 is Example 1, Comparative Example 1 and Comparative Example These are the smoking sensory evaluation results for smoking articles manufactured according to 4 and stored at room temperature for 2 months.

2 and 3, the outward strength in the cigarette of Comparative Example 4 to which the fragrance printing was applied compared to the cigarette of Comparative Example 1 to which the fragrance printing was not applied (that is, there is no tip paper rubbing by the smoker's finger and the smoker's mouth It can be seen that the intensity of the scent before the saliva is delivered) has significantly increased. In contrast, in the cigarette of Example 1 to which the flavor carrier printing was applied, the outward strength was slightly increased compared to the cigarette of Comparative Example 1, but it can be seen that it had a much lower value than that of Comparative Example 4.

It can be seen that the intensity of scent remaining on the finger after smoking significantly increased in Comparative Examples 4 and 1 compared to Comparative Example 1, and that Example 1 slightly increased compared to Comparative Example 4. It can be seen that the intensity of finger cigarette smell after smoking decreased in Comparative Examples 4 and 1 compared to Comparative Example 1, and that Example 1 decreased compared to Comparative Example 4.

Considering the fact that the outward strength was lower in Example 1 compared to Comparative Example 4 and that the fragrance intensity remaining on the finger after smoking showed a higher value in Example 1 compared to Comparative Example 4, the fragrance material was carried It can be seen that, when printed (Example 1), the amount of expression before smoking is relatively reduced and the amount of expression of flavor during smoking is relatively greater than when no carrier is applied (Comparative Example 4).

Tobacco taste intensity did not show a significant difference in all of Example 1, Comparative Example 1, and Comparative Example 4, so it is expected that taste deterioration due to application of fragrance printing will not occur.

Experimental Example 9: Smoking sensory evaluation according to whether microcapsules were additionally applied

In order to confirm the sensory characteristic change depending on whether the microcapsule was added or not, the outward appearance intensity, the tobacco taste intensity, the cigarette smell intensity of the smoking articles according to Examples 10 to 12 and Comparative Example 1, the intensity of the odor of the finger after smoking, the intensity of the scent remaining on the finger after smoking And sensory evaluation was performed on the satisfaction of the scent left on the finger. Sensory characteristic evaluation was conducted for 20 evaluation panel members using the smoking articles of Examples 10 to 12 and Comparative Example 1, and a total score of 8 was used as the standard.

4 is a result of the sensory evaluation of smoking for smoke-free articles produced according to Examples 10 to 12 and Comparative Example 1 and 2 weeks have elapsed.

Referring to FIG. 4 , as the weight of the binder and/or microcapsules in the fragrance carrier ink increases, the outward strength, the strength of the fragrance remaining on the finger after smoking, and the satisfaction of the fragrance remaining on the finger generally increase, and the intensity of the finger cigarette smell after smoking is a decreasing trend was observed.

In all of Examples 10 to 12, it can be seen that the increase in the intensity of the scent remaining on the finger after smoking compared to Comparative Example 1 is greater than the increase in the outward strength compared to Comparative Example 1. It can be seen that the fragrance is substantially expressed by the smoking behavior of the smoker while not being substantially expressed.
