1 is a view showing a schematic configuration of a smoking article to which tip paper is applied according to some embodiments of the present invention.

Referring to FIG. 1, the smoking article 100 includes a filter unit 110 in which a filter wrapper 110a is wrapped, a smoking material unit 120 in which a smoking material wrapper 120a is wrapped, and the filter unit 110 and It may include a tip paper 130 for bonding the smoking material portion 120.

The filter unit 110 is disposed downstream of the smoking material unit 120 and may be a region through which the aerosol material generated from the smoking material unit 120 is passed just before the user inhales.

The filter unit 110 may be formed of various materials, for example, the filter unit 110 may be a cellulose acetate filter.

In some embodiments, the filter unit 110 may be a cellulose acetate filter in which the fragrance material is not flavored, but is not limited thereto, and the filter unit 110 is a transfer jet nozzle system (TJNS) filter in which the fragrance material is flavored. I can.

In some embodiments, the filter unit 110 may be a tube-shaped structure including a hollow inside. In addition, the filter unit 110 may be manufactured by inserting a structure such as a film or tube made of the same or different material into the interior (eg, hollow).

Meanwhile, when the filter unit 110 is manufactured, the hardness of the filter unit 110 may be adjusted by adjusting the content of the plasticizer. Triacetin may be applied as a 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.

The filter unit 110 of the present embodiment is illustrated as a mono filter made of a single filter, but 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 including two acetate filters in order to increase filter efficiency.

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

The material forming the film of the capsule may be a natural material, starch and/or a gelling agent. For example, in the case of a natural material film, 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 a gelling aid, calcium chloride can be used, for example. Further, a plasticizer may be further used as a material for forming a film of the capsule. Here, glycerin and/or sorbitol can be used as the plasticizer.

The contents of the capsule may contain flavorings such as menthol and plant essential oils, but are 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 wrapper so that the capsule contained in the filter unit 110 is crushed by the smoker so that the capsule contents discharged to the outside of the capsule cannot pass through the filter wrapper 110a. In some embodiments, 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 from the smoking material unit 120 is passed just before the user inhales.

The smoking material part 120 may contain an aerosol-generating material. For example, the smoking material unit 120 may include tobacco strands. The smoking material portion 120 may have an elongated rod shape, and its length, circumference, and diameter may vary.

In some embodiments, the aerosol-generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

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

In some embodiments, the smoking material unit 120 pulverizes the tobacco raw material, mixes a solvent and various additives, prepares it in a slurry form, and then dries it to form a sheet, and then processes the sheet to form a piece such as a rod. Formed reconstituted tobacco material. For example, the smoking material portion 120 includes a plurality of strands of tobacco material, and one such strand has a length of approximately 10 mm to 14 mm (e.g., 12 mm) and a width of approximately 0.8 mm to 1.2 mm (e.g. For example, 1mm) and the thickness may be approximately 0.08mm to 0.12mm (eg, 0.1mm), but is not limited thereto.

By allowing the smoking material part 120 to include a plurality of strands processed in the form of a wide tobacco sheet, the density of the tobacco material filled in the smoking material part 120 increases, thereby increasing the amount of aerosol generation, and smoking Smoking characteristics of the material part 120 may be improved.

The smoking material part 120 may be wrapped by a 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 the smoothness and retrospectiveness 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 are not limited thereto.

In addition, although not shown, the smoking material wrapper 120a may have a double wrapper structure. Specifically, the smoking material wrapper 120a is in contact with the smoking material part 120 and an inner wrapper (not shown) surrounding the smoking material part 120 and an outer wrapper in contact with the inner wrapper and surrounding the outside of the inner wrapper (outer wrapper) can be included.

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

In some embodiments, the tip paper 130 may be made of a non-porous wrapper 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 added to the tip paper 130. Silicon may be used as an example of a predetermined material, but is not limited thereto. For example, silicon has characteristics such as heat resistance with little change depending on temperature, oxidation resistance that does not oxidize, resistance to various chemicals, water repellency to water, or electrical insulation. However, even if it is not silicon, any material having the above-described characteristics may be applied or coated on the tip paper 130 without limitation.

The tip paper 130 may prevent the filter unit 110 from burning. For example, when the smoking material unit 120 is burned to a portion adjacent to the filter unit 110, there is a possibility that the filter unit 110 is also burned. Even in this case, since the tip paper 130 includes a non-combustible material, a phenomenon in which the filter unit 110 is burned can be prevented.

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 in order to reduce the smell of cigarettes due to smoke generated by smoking. Various attempts have been made, such as forming a wrapper structure or applying a water-soluble fragrance carrier containing fragrance. However, the effect of reducing smoke from the various attempts described above is aside, and since the part where the smoker's finger directly touches during smoking is the tip paper 130, not the smoking material wrapper 120a, in order to effectively reduce the smell of finger cigarettes, smoking There is a need for a technique for reducing the smell of finger cigarettes that can be applied directly to the tip paper 130 rather than the material wrapper 120a.

Accordingly, the tip paper 130 of the present invention includes a fragrance carrier composed of a fragrance material for masking tobacco odor and 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 made of 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 aroma carrier ink comprises the steps of: i) adding a carrier material to ethanol and stirring for about 30 to 60 minutes; ii) adding a perfume material to the ethanol solution to which the carrier material is added, and stirring for about 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 about 15 to 45 minutes.

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

The fragrance carrier printing process may be performed by mixing the fragrance carrier with the ink used in the over print varnish (OPV) process performed on the tip paper, but preferably the OPV After the process, it may be performed as a separate printing process 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.

In the present invention, the carrier material is characterized in that it is not soluble in water, isopropyl alcohol, or the like, 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 (e.g., beta-cyclodextrin) that encloses the fragrance material to the above-described smoking material wrapper 120a. This is because it is practically impossible to apply as it is to (130). Specifically, when the water-soluble aroma carrier method is applied to the tip paper 130, water must be used as an 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 printing of the tip paper 130 Difficulty occurs in the drying process after that, 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 to dry the ink having increased surface energy as described above, the tip paper curl is increased. On the contrary, in the case of printing a perfume material on the tip paper without applying the above carrier method, the perfume material is lost to the outside of the smoking article during the storage period of the tip paper due to the nature of the tip paper disposed at the outermost part of the smoking article. , Light/humidity, and other storage conditions cause discoloration of the tip paper.

In contrast, when the carrier material applied to the tip paper as in the present invention is applied as a polymer material such as 2-hydroxypropyl-beta-cyclodextrin, which is soluble in ethanol while containing a hydrophobic fragrance material, ink Since ethanol can be used as a solvent, an ink having a surface energy of about 20 mN/m to 50 mN/m can be used. Accordingly, printing and drying process of tip paper can be applied, and only workability in manufacturing smoking articles is possible. In addition, since there is no discoloration issue, storage stability can also be secured.

On the other hand, the fragrance material enclosed in the carrier material is expressed outside of the tip paper 130 (that is, outside of the smoking article 100) in response to moisture, saliva, or friction. The perfume material is transferred to the smoker's finger gripping the tip paper portion, thereby performing the role of masking the smell of finger cigarettes.

Further, the fragrance material is enclosed in the carrier material before moisture or saliva (eg, saliva) is transferred from the smoker 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 that the fragrance is lost as the storage period elapses or the problem that unnecessary fragrance is generated while the smoker is simply storing the smoking material.

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

Meanwhile, as will be described later with reference to Tables 7 to 8, the combined weight ratio of the vanillin and ethylvanillin in consideration of the discoloration issue of the tip paper may be more than 0% and 50% or less with respect to the total weight of the perfume material. Preferably, the weight ratio of vanillin to the total weight of the perfume material may be more than 0% and not more than 30%, and the weight ratio of ethyl vanillin may be more than 0% and not more than 20%. 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 ethyl vanillin may be about 5% to 15%.

The fragrance material may include various components other than the vanillin and ethyl vanillin, and Table 1 shows the components of the fragrance material confirmed that the above-described finger cigarette odor reduction effect is maximized.

In some embodiments, the perfume material may have a composition ratio in the order of rosemary oil, vanillin, fermented alcohol, labandin oil, ethyl vanillin, and eucalyptol. The content ratio of the vanillin and the eucalyptone is about 2.5:1 to 3.5:1 (preferably, about 3:1), and the content ratio of the ethyl vanillin and the labandin oil contained in the fragrance 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 substances than necessary, there may be a problem that the fragrance is transferred to other tip papers other than the tip paper of the present invention to which the fragrance should not be applied during the mass production process. There may also be a problem in which discoloration occurs.

In order to solve this problem, the weight ratio of the fragrance material to the total weight of the fragrance carrier ink may be greater than 0% and less than or equal to 3%, and the weight ratio of the carrier material may be greater than about 0% and less than or equal to 30%. Preferably, the weight ratio of the fragrance material to the total weight of the fragrance carrier ink is greater than about 0% and less than or equal to 1.5%, and the weight ratio of the carrier material may be greater than about 0% and less than or equal to 15%. 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 acrylic 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 enclosed in the fragrance carrier. That is, through the binder, it is possible to better preserve the fragrance material or fragrance carrier, which may be lost during the storage period after manufacture of the smoking article, on the tip paper.

Meanwhile, in order for the binder to perform the role of preserving the fragrance material described above and to secure printing workability, the binder needs an appropriate viscosity. For this purpose, the binder has a molecular weight of approximately 1,000 to 30,000 and a glass transition temperature. It may be a polymer material of approximately 50 ℃ to 100 ℃. Preferably, the binder may be a polymer material having a molecular weight of about 3,000 to 20,000 and a glass transition temperature of about 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, resulting in poor workability and a decrease in inherent performance of the binder.

In addition, as will be described later with reference to Table 4, as the amount of the binder applied increases, the scent retention power tends to increase. However, if the amount of the binder applied is too large, the tip paper curl increases, which may cause difficulty in manufacturing smoking articles.

To solve this difficulty, the weight ratio of the binder to the total weight of the fragrance carrier ink may be greater than about 0% and less than or equal to 15%. Preferably, the weight ratio of the binder to the total weight of the fragrance carrier ink may be approximately 5% to 10%.

The microcapsules that may be included in the fragrance carrier ink may include polyvinyl alcohol (PVA), a fragrance, and a crosslinking agent. Specifically, the core of the microcapsule is an ethanol-based fragrance, the 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 fragrance may have the same composition as the fragrance material contained in the fragrance carrier material described above.

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

In some embodiments, the weight ratio of the microcapsules to the total weight of the fragrance carrier ink may be greater than about 0% and less than or equal to 25%, preferably about 5% to 20%. Through this, it is possible to solve the problem of excessive expression before smoking due to cracking of the microcapsules and/or the problem that the surface of the tip paper is contaminated by the capsule shell and becomes rough, which may occur as the microcapsule is excessively contained.

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

The microcapsules include: i) stirring the ethanol-based fragrance and polyvinyl alcohol at room temperature for about 15 to 45 minutes; ii) adding a crosslinking agent to a 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 more 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 the stirred solution at room temperature for about 30 minutes to 2 hours.

Experimental Example 1: Evaluation of drying and curling properties after printing of tip paper

In order to check the drying and curl characteristics of the tip paper prepared according to the embodiment of the present invention after printing, 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 The curl was 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 aromatic carrier was all found to be good. However, the tip paper in Comparative Example 2 to which the water-soluble flavor carrier printing was applied was confirmed that the ink was incompletely dried after the printing and drying process, and this was when water was used as an ink solvent when printing the water-soluble flavor carrier, so that the surface energy of the ink was 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 shown, but a high value of about 12 mm. It was confirmed that the tip paper curl of was generated, so that the tip paper in Comparative Example 3 could not be applied to the mass production process of cigarettes.

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

Example 2

For the example, the medium part and the filter part were separated by removing the tip paper of the cigarette prepared for testing. The separated medium part and the filter part were prepared by applying a fragrance carrier printing process using an OPV process and an ethanol-based fragrance carrier ink containing 0.4% of a fragrance material, and a smoking article combined with a tip paper having a porosity of about 100 CU. Was 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 in Examples 2 to 5, smoking articles were prepared in the same manner as in Example 2, except that the fragrance printing process was performed by stirring in the ink without carrying the fragrance material.

Experimental Example 2: Evaluation of index material for reducing finger odor of tip paper-no binder applied

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

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

As shown in Table 3, vanillin and ethylvanillin components were detected in all the examples, and it was confirmed that the vanillin and enylvanillin components detected through this contact with a finger to mask odors. , Looking at the analysis results in Example 4 and Comparative Example 4, even if the content of the perfume material in the ink is the same, the perfume material is contained in the carrier material than in the case of performing fragrance printing without carrying the perfume material (Comparative Example 4). It can be seen that more vanillin and ethyl vanillin components were detected in the case where the fragrance carrier printing was performed in contact with each other (Example 4).

Further, looking at the analysis results in Examples 2 to 5, the amount of vanillin and ethylvanillin components expressed in the tip paper tended to increase as the content of the perfume material in the fragrance carrier ink increased. However, in the case of Example 5, in which the content of the carrier-based fragrance material was 1.5%, during the mass production process, a problem occurred in that the fragrance was transferred to other tip papers to which the fragrance should not be applied, and thus the carrier-based fragrance material In Example 4 in which the content of is 1.25%, it was confirmed that the effect of reducing the smell of fingers due to smoking was excellent, and at the same time, it was within the range of mass production of cigarettes.

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 flavor 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 content of the binder in the flavor carrier ink increased, the amount of vanillin and ethylvanillin components expressed in the tip paper tended to increase. However, in the case of Example 9 in which the binder content is 15%, the problem of excessive increase in the tip paper curl occurs, and when the content of the binder is 5% to 10%, the effect of reducing finger odor due to smoking is excellent and at the same time. 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 the ethanol-based flavor carrier ink contained 5.0% of the microcapsules. As for the microcapsules, a microcapsule having a diameter of approximately 1.5um to 5.0um was used, in which the core was an ethanol-based fragrance, the shell was composed 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 flavor carrier ink.

Surface contamination of tip paper

As shown in Table 5, as the content of the microcapsules in the flavor 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 microcapsule content is 25%, the outward strength generated in the storage state of the cigarette before smoking is excessively increased, and the surface contamination of the tip paper due to cracking of the microcapsules occurs, and the content of the microcapsules is 10% to 10%. When the concentration was 20%, it was confirmed that the effect of reducing finger odor due to smoking became excellent, and the problem of outward strength and surface contamination of the tip paper could be solved.

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

The physical properties of the tip paper were analyzed to confirm the print workability of the tip paper manufactured according to the embodiments of the present invention and the workability characteristics of a subsequent process for manufacturing a cigarette after printing, and the results are shown in Table 6. . In the analysis of the physical properties of the tip paper in Experimental Example 5, the tip paper before being assembled to 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 adhesive problem between the front and back sides of the tip paper that may occur due to transfer to the back side by curling the paper with less drying ink Was not generated, the slip property was satisfactory without the problem that the surface of the tip paper was slippery and the surface was too rough, and the tip paper curl was also within an appropriate numerical range. Accordingly, it was confirmed that there was no problem in printing workability of a fragrance carrier using a fragrance carrier ink containing a fragrance material, a binder, and a microcapsule within the scope of the above examples.

Example 14

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

Example 15

A smoking article was prepared in the same manner as in Example 14, except that 10% vanillin was contained in the perfume material.

Example 16

Example 18

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

Comparative Example 5

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

Experimental Example 6: Evaluation of color stability according to change of vanillin content in perfume material

To evaluate the color stability of the tip paper according to the change in the vanillin content in the perfume material, the degree of color change of the cigarette immediately after manufacture and the cigarette after 2 months of manufacture is numerically expressed as the color difference (△E) in the CIELAB color space. It is shown in 7. 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 vanillin content in the fragrance material increases (the content of ethyl vanillin is fixed at 10%). In particular, it can be seen that in Examples 16 and 17 where the vanillin content is 30% or more, the degree of discoloration is rapidly increased to a value that may be observed with the naked eye, and in Examples 13 to 15 where the vanillin content 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 content 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 (Comparative Example 5).

In particular, it can be seen that in Examples 19 to 21 in which the ethyl vanillin content is 20% or more, the degree of discoloration is rapidly increased to a value that may be observed with the naked eye, and in Example 15 and the ethyl vanillin content is 5% to 10%. In 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 strength of smoking articles according to Example 1, Comparative Example 1 and Comparative Example 4, cigarette taste strength, finger cigarette odor strength after smoking, and finger after smoking Sensory evaluation was performed on the remaining fragrance intensity and satisfaction on the remaining fragrance on the fingers.

The sensory characteristics evaluation was conducted on 20 evaluation panel members using the smoking articles of Example 1, Comparative Example 1, and Comparative Example 4, and was based on a total of 8 points.

2 is a smoking sensory evaluation result of smoking articles prepared according to Example 1, Comparative Example 1, and Comparative Example 4 and then stored for 2 weeks at room temperature, and FIG. 3 is a view showing Example 1, Comparative Example 1, and Comparative Example. This is the result of smoking sensory evaluation of 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 incense printing was applied compared to the cigarette of Comparative Example 1 to which incense printing was not applied (that is, there was no rubbing of the tip paper by the smoker's finger and the smoker's mouth It can be seen that the intensity of the fragrance in the state before the saliva was delivered) was remarkably increased. In contrast, in the cigarette of Example 1 to which the fragrance carrier printing was applied, the outward strength was slightly increased compared to the cigarette of Comparative Example 1, but it can be seen that the outward strength was much lower than that of Comparative Example 4.

It can be seen that the incense intensity remaining on the fingers after smoking was significantly increased in Comparative Example 4 and Example 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 the finger cigarette smell after smoking was decreased in Comparative Example 4 and Example 1 compared to Comparative Example 1, and that Example 1 was decreased compared to Comparative Example 4.

In consideration of the fact that the extroversion intensity was lower in Example 1 compared to Comparative Example 4 and the scent intensity remaining on the finger after smoking was higher in Example 1 compared to Comparative Example 4, the fragrance material was carrierized. In the case of printing (Example 1), compared to the case where no carrierization was applied (Comparative Example 4), the amount of expression toward smoking was relatively reduced, and the amount of expression toward smoking was relatively increased.

The taste intensity of cigarettes did not show a significant difference in all of Example 1, Comparative Example 1, and Comparative Example 4, and it is expected that a decrease in taste sensation due to the application of fragrance printing would not occur.

Experimental Example 9: Smoking sensory evaluation according to whether microcapsules were added or not

In order to confirm the change in sensory properties depending on whether or not additional microcapsules were applied, the outward intensity of smoking articles according to Examples 10 to 12 and Comparative Example 1, the intensity of cigarette taste, the intensity of the smell of cigarette fingers after smoking, and the intensity of the fragrance remaining on the fingers after smoking. And sensory evaluation was performed on the satisfaction with the fragrance remaining on the finger. Sensory property evaluation was conducted on 20 evaluation panel members using the smoking articles of Examples 10 to 12 and Comparative Example 1, based on a total of 8 points.

4 is a result of smoking sensory evaluation for smokeless articles 2 weeks elapsed after being manufactured according to Examples 10 to 12 and Comparative Example 1. FIG.

Referring to FIG. 4, as the content of the binder and/or microcapsule in the fragrance carrier ink increases, the intensity of the outward appearance, the intensity 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 cigarette smell after smoking is There was a tendency to decrease.

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