In some embodiments, the length 230L1 of the transfer wrapping paper 230 may be about 33 mm to 37 mm. In the case where the length of the filter 210 for the smoking article is 30 mm, the length 230L2 of the transfer wrapper 230 overlapping the smoking material portion 120 may be about 3 mm to 7 mm.

The smoking article 200 may have a long-extending rod-like shape, and its length and diameter may be changed. For example, the length of the smoking article 200 may be about 45 mm to 100 mm, and the diameter may be about 5 mm to 9 mm.

However, considering the discoloration caused by the basis weight and composition of the above-mentioned smoking material wrapping paper 120a, the total length of the smoking material 200 is about 90mm to 110mm (preferably about 100mm), and the circumference (or the smoking material wrapping paper 120a) The width of the first filter 212 is about 14mm to 20mm (preferably about 17mm), the length of the smoking material portion 120 is about 65mm to 75mm (preferably about 70mm), and the length 212L of the first filter 212 is about 10mm to 20mm (more It is preferably about 15 mm), and the length 214L of the second filter 214 is about 10 mm to 20 mm (preferably about 15 mm).

The first capsule 212c and the second capsule 214c may have a spherical shape, and the diameter 212c_D of the first capsule 212c and the diameter 214c_D of the second capsule 214c may be about 2.6 mm to 3.0 mm. In some embodiments, the diameter 212c_D of the first capsule 212c and the diameter 214c_D of the second capsule 214c may be the same, but the present invention is not limited thereto.

The first capsule 212c may be arranged at a position where an ordinary smoker grasps the smoking article 200 when smoking. Preferably, the first capsule 212c may be located at the downstream end of the second filter 214, that is, at a position spaced from the downstream end of the smoking article 200 in the upstream direction by about 18 mm to 27 mm. As a more specific example, the center point of the first capsule 212c may be located at a position separated from the downstream end of the smoking article 200 by about 21 mm to 24 mm in the upstream direction, and the upstream end of the first capsule 212c may be located downstream from the smoking article 200 The ends are spaced about 22.5 mm to 25.5 mm in the upstream direction, and the downstream end of the first capsule 212c may be positioned about 19.5 mm to 22.5 mm in the upstream direction from the downstream end of the smoking article 200.

The first capsule 212c and the second capsule 214c may have a separation distance Cap_D of about 10 mm to 14 mm. In other words, the first capsule 212c may be located at a position spaced from the second capsule 214c by about 10 mm to 14 mm in the upstream direction.

The second perforated area 214P may be formed on the wrapping paper 214a, 216, 230 located at the portion covering the second filter 214. As shown in Figure 3, the second perforated area 214P may have double perforations, that is, it may have a plurality of first holes 214P1 formed along the outer peripheral surface of the transfer wrapping paper 230 and a downstream edge of the first hole 214P1. A plurality of second holes 214P2 are formed on the outer peripheral surface of the transfer wrapping paper 230, but the present invention is not limited to this. For example, unlike the one shown in Figure 3, only one of the plurality of first holes 214P1 and the plurality of second holes 214P2 may be provided in the second perforated area 214P (single perforation), or may be in addition to the plurality of first holes. Additional holes other than the hole 214P1 and the plurality of second holes 214P2 may be further provided in the second perforated area 214P.

For example, the plurality of first holes 214P1 and the plurality of second holes 214P2 may respectively include four to ten holes (holes), and these holes may be formed at a certain interval along the outer peripheral surface of the transfer wrapping paper 230, but The present invention is not limited to this. The diameter of each hole may be about 0.02 mm to 0.08 mm (for example, 0.05 mm), but the present invention is not limited thereto.

The holes can be formed by an on-line perforation method, that is, by using a non-porous transfer wrapper to make a cigarette and then perforating the filter part. A laser can be used to perform online perforation, but the present invention is not limited to this. As described above, when perforating on-line to form a hole, as shown in Figure 3, the hole can not only be formed in the transfer wrapping paper 230, but can also extend to the combined wrapping paper 216, the second wrapping paper 214, and then to the second wrapping paper. Part of the area outside the filter 214, so that the outside air can flow from the outside to the inside of the second filter 214 through the second perforated area 214P. The external air introduced through the second perforation 214P can be mixed with mainstream smoke and delivered to the smoker.

In some embodiments, the plurality of first holes 214P1 and the plurality of second holes 214P2 may have a separation distance 214Pw of about 0.5 mm to 1.5 mm. In other words, the plurality of first holes 214P1 may be spaced from the plurality of second holes 214P2 by about 0.5 mm to 1.5 mm in the upstream direction.

In some embodiments, the plurality of first holes 214P1 may be separated from the upstream end of the transfer wrapping paper 230 by about 22mm to 25mm (214P_TEd), and the plurality of second holes 214P2 may be separated from the downstream end of the second filter 214 by about 9mm. To 12mm (214P_MEd).

As shown in Figure 3, the plurality of first holes 214P1 and the plurality of second holes 214P2 may be located in an area that does not overlap with the second capsule 214c, that is, upstream of the second capsule 214c.

Figure 4 is a partial cross-sectional view in the direction of the central axis of smoking articles according to some embodiments of the present invention.

In Fig. 4, the same reference numerals as those in Figs. 1 to 3 denote the same elements, and for convenience of description, repeated description will be omitted here.

4, the smoking article 300 may include a smoking material portion 120, a smoking material wrapper 120a, a filter 210 for the smoking article, and an adapter wrapper 330, and the filter 210 for the smoking article may include a first filter The filter 212, the second filter 214, the first wrapping paper 212a, the second wrapping paper 214a, the first capsule 212c, the second capsule 214c and the combined wrapping paper 216.

The first perforated area 312P may be formed on the transfer wrapping paper 330 of the smoking article 300. As shown in Figure 4, the first perforated area 312P may have double perforations, that is, it may have a plurality of first holes 312P1 formed along the outer peripheral surface of the transfer wrapping paper 330 and a downstream edge of the first hole 314P1. A plurality of second holes 312P2 are formed on the outer peripheral surface of the transfer wrapping paper 330, but the present invention is not limited to this. For example, unlike the one shown in Figure 4, only one of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be provided in the first perforated area 312P (single perforation), or may be further provided in addition to the plural Additional holes other than the first hole 312P1 and the plurality of second holes 312P2 are in the first perforated area 312P.

Each of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be formed at a certain interval along the outer peripheral surface of the transfer wrapping paper 130, but the present invention is not limited thereto.

The holes can be formed by an off-line perforation method, that is, by using a pre-perforated adapter wrapper 330 to manufacture cigarettes. A laser can be used to perform offline perforation, but the present invention is not limited to this.

By forming a plurality of first holes 312P1 and/or a plurality of second holes 312P2, the porosity of the transfer wrapping paper 330 in the first perforated area 312P can be about 190 CU to 210 CU. In other words, the plurality of first holes 312P1 and/or the plurality of second holes 312P2 may be perforated so that the porosity of the transfer wrapping paper 330 is approximately 190 CU to 210 CU. This is because when the porosity of the transfer wrapping paper 330 is less than about 190 CU, the actual benefit for increasing the transfer rate of the capsule content solution is small. When the porosity of the transfer wrapping paper 330 is about 210 CU or When larger, mainstream smoke may leak through the first perforated area 312P.

As described above, when the perforation is formed by off-line perforation, the porosity of the transfer wrapping paper 330 in the first perforation area 312P becomes approximately 190 CU to 210 CU, so that, as shown in FIG. The paper 330 does not extend to combine the wrapping paper 216 and the first wrapping paper 212a. As a result, the smoker ruptures the first capsule 212c so that the capsule content solution released to the outside of the first capsule 212c can be better delivered to the smoker's hand, and the perforation does not extend to the joint wrapping paper 216 and the first wrapping paper 212a Therefore, it is possible to prevent mainstream smoke from leaking to the outside of the smoking article 300.

In some embodiments, the plurality of first holes 312P1 and the plurality of second holes 312P2 may have a separation distance 312Pw of about 1 mm to 3 mm. In other words, the plurality of first holes 312P1 may be spaced from the plurality of second holes 312P2 by about 1 mm to 3 mm in the upstream direction.

In some embodiments, the spacing distance 312Pw between the plurality of first holes 312P1 and the plurality of second holes 312P2 of the first perforated area 312P may be the plurality of first holes 214P1 and the plurality of second holes 214P2 of the second perforated area 214P The separation distance 214Pw is about 1.5 to 3 times (for example, 2 times). For example, the separation distance 312Pw may be about 2 mm, and the separation distance 214Pw may be about 1 mm, but the present invention is not limited thereto.

In some embodiments, the plurality of first holes 312P1 may be approximately 10mm to 13mm (312P_Ted) away from the upstream end of the transfer wrapping paper 330, and the plurality of second holes 312P2 may be away from the downstream end of the second filter 214 20mm to 23mm (312P_MEd).

In some embodiments, the distance Per_D between the plurality of second holes 312P2 of the first perforated area 312P and the plurality of first holes 214P1 of the second perforated area 214P may be about 9 mm to 10 mm.

On the other hand, as shown in Fig. 4, unlike the plural first holes 214P1 and the plural second holes 214P2 of the second perforated area 214P, the plural first holes 312P1 and the plural second holes 312P1 of the first perforated area 312P The two holes 312P2 are located in an area overlapping the first capsule 212c, so that the smoker ruptures the first capsule 212c so that the capsule content solution released to the outside of the first capsule 212c can be better delivered to the smoker's hand.

As described above, in the smoking articles 100, 200, 300 according to the embodiment of the present invention, the first fragrance material including ethyl vanillin (and the first fragrance material such as raspberry ketone) is coated on the smoking material wrapping paper 120a. The second fragrance material). In addition, the first filter 212 may include a first capsule 212c containing a fragrance capable of reducing the smoker’s hand odor (and bad breath), and the second filter 214 may include a fragrance capable of reducing the smoker’s The second capsule 214c of the fragrance of bad breath can reduce the odor (sidestream smoke odor, hand odor, and bad breath) that may be generated due to smoking and prevent the reduction of the smell during smoking.

On the other hand, flavors including a first flavor material such as ethyl vanillin (and a second flavor material such as raspberry ketone) can be added to the smoking material wrapping paper in various ways. For example, before the smoking article is manufactured, the fragrance can be added to the smoking material wrapping paper 120a described with reference to FIGS. 1 to 4, and then it is suitable for adding fragrance directly, and is suitable for cigarettes. In addition, after the smoking article is manufactured, the fragrance can be added to the smoking article housing containing the manufactured smoking article and transferred to the smoking article. Hereinafter, a smoking article shell according to another embodiment of the present invention will be described in detail.

Figure 5 is a schematic diagram showing the structure of a smoking article shell according to some embodiments of the present invention, and Figure 6 is a plan development view of an inner liner to be included in the smoking article shell.

Referring to FIGS. 5 and 6, the smoking article housing 1000 may include a housing main body 1100 accommodating the smoking article 100 and an inner liner 1200 arranged between the smoking article 100 and the housing main body 1100 in a manner to surround the smoking article 100.

The housing body 1100 may include a housing lower body 1110 and a housing upper body 1120. The upper part of the housing lower body 1110 is open and a space is formed inside to accommodate the smoking article 100. The housing upper body 1120 is connected to the housing lower body 1110 in a folded manner. The upper rear end opens and closes the upper part of the lower main body 1110 of the housing.

The inner liner 1200 may be arranged in a manner to surround at least one side of the smoking article 100, preferably, may be arranged in a manner of surrounding the smoking article 100 from four sides, so as to more stably protect the smoking article and prevent the smoking article 100 in the shell body 1100 Easily exposed to the outside. For example, the inner liner 1200 may be folded along the inner liner folding line 1200f shown in FIG. 6 to surround the smoking article 100 from four directions.

The inner liner 1200 may include inner liner riding stitching 1200p, which is used to easily separate and remove the inner liner 1200a of the front upper area from the inner liner 1200b of the lower front area, so that the smoker can easily take out the smoking article 100.

In order to transfer the fragrance ingredients to the smoking article 100 protected in the smoking article housing 1000, at least a part of the inner liner 1200 may be coated with a fragrance composition.

In some embodiments, the perfume composition may be applied to only one side of the inner liner 1200 and not the other side opposite to the above-mentioned one side. More specifically, the fragrance composition may only be applied to the side of the inner liner 1200 that is in contact with the smoking article 100, and not applied to the side of the inner liner 1200 that is in contact with the inner side of the casing body 1100. The other side. On the other hand, in order to transfer the fragrance composition only to the smoking article 100 and minimize the leakage of the fragrance composition toward the outer shell body 1100 or to the outer area of the outer shell body 1100, the other side of the aforementioned side of the inner liner 1200 may be Coated with aluminum foil, etc. or treated with oil resistance.

In some embodiments, the fragrance coated on the inner liner 1200 may include a first fragrance material selected from vanillin, ethyl vanillin, and ethyl vanillin glucoside, and, in addition to the first fragrance material The materials can include selected from raspberry ketone, menthol, methoxyacetophenone, γ-undecanolide, methyl anthranilate, cinnamic acid, myristic acid, anise oil, lemon oil and orange At least one or more second fragrance materials in oil. As an example, relative to the total weight of the fragrance composition, the fragrance composition may include about 20% by weight of ethyl vanillin, about 5% by weight of raspberry ketone, about 30% by weight of menthol, and about 45% by weight of ethanol. .

In some embodiments, the total length 1200L of the liner 1200 included in a smoking article shell 1000 may be about 220mm to 230mm (for example, 227mm), and the width 1200W may be about 65mm to 75mm (for example, 70mm). The total amount of fragrance on the liner 1200 can be about 200 mg, wherein the amount of ethyl vanillin can be about 40 mg, the amount of raspberry ketone can be about 10 mg, the amount of menthol can be about 60 mg, and the amount of ethanol It can be about 90 mg. Assuming that the fragrance composition applied on the inner liner 1200 is transferred to the 20 smoking articles 100 contained in the smoking article housing 1000, one tobacco may include about 2 mg of ethyl vanillin and about 0.5 mg of raspberry. Ketones and approximately 3 mg of menthol. Relative to the total amount of one tobacco, one tobacco may include about 0.6% by weight of ethyl vanillin, about 0.15% by weight of raspberry ketone, and about 0.9% by weight of menthol.

On the other hand, the length and width of the inner liner 1200, the total amount of fragrance applied to the inner liner 1200, etc. are just values as an example, and the present invention is not limited thereto. The total amount of fragrance applied on the inner liner 1200 (or the amount of ethyl vanillin, etc.) may depend on the area of the inner liner 1200. For example, the total length 1200L of the liner 1200 may be about 150mm to 160mm (for example, 155mm), the width 1200W may be about 110mm to 120mm (for example, 114.5mm), and the total amount of perfume applied on the liner 1200 may be About 223.4mg.

In some embodiments, the basis weight of the fragrance applied on the inner liner 1200 may be about 1 g/m ² to 20 g/m ² , preferably, it may be about 10 g/m ² to 15 g/m ² . Also, the basis weight of ethyl vanillin coated on the inner liner may be about 0.2 g/m ² to 4 g/m ² , preferably, it may be about 2 g/m ² to 3 g/m ² . Also, the basis weight of the raspberry ketone coated on the inner liner may be about 0.05 g/m ² to 1 g/m ² , preferably, it may be about 0.5 g/m ² to 0.75 g/m ² . The basis weight of the menthol applied to the inner liner may be about 0.3 g/m ² to 6 g/m ² , preferably, it may be about 3 g/m ² to 4.5 g/m ² .

As described above, when the fragrance is applied to the inner liner 1200 included in the smoking article shell 1000, the first fragrance material (and the second fragrance material) is transferred to the smoking article 100, thereby covering up when the smoking article 100 is smoked The sidestream smoke generated to reduce the smell of tobacco. The flavor-coated liner 1200 can be used with the smoking products described with reference to Figs. 1 to 4, which are suitable for cigarette papers with added flavors, but the present invention is not limited to this, and can also be used with smoking products suitable for non-flavored cigarette papers. Use products together. For example, the fragrance is coated on the inner liner 1200 of the smoking article shell 1000, and the smoking article included in the smoking article shell 1000 may be a smoking article without added fragrance.

Hereinafter, the structure of the present invention and its effects will be described in more detail through examples and comparative examples. However, these examples are only used to describe the present invention more specifically, and the scope of the present invention is not limited by these examples.

Example 1

After removing the cigarette paper surrounding the tobacco material of the cigarette used in the test of the example, a cigarette suitable for the cigarette paper having the physical characteristics of Example 1 in Table 1 was prepared.

Example 2

After manufacturing the cigarette to which the cigarette paper having the physical properties of the following Comparative Example 1 is applied, the manufactured cigarette is stored in the outer casing of the smoking article using the inner liner coated with the fragrance composition described with reference to FIGS. 5 to 6 In, and then kept for about two months. The smoking product casing containing cigarettes is stored in an air-conditioned room with a temperature of about 22°C and a humidity of about 62.5%.

The length of the inner liner is about 227mm, the width is about 70mm, and the fragrance liquid of the inner liner is evenly applied to the side of the inner liner that is in contact with the cigarette, and not to the outer shell of the smoking article shell. The inner side of the main body touches the other side. Aluminum foil is coated on the other side in contact with the inner side of the shell body.

The total amount of the inner liner fragrance evenly applied to the inner liner is about 200 mg, relative to the total weight of the inner liner fragrance, the content of ethyl vanillin is about 20% by weight (about 40 mg), and the amount of raspberry ketone The content is about 5% by weight (about 10 mg), the content of menthol is about 30% by weight (about 60 mg), and the content of ethanol is about 45% by weight (about 90 mg). The basis weight of the fragrance liquid coated on the inner liner is about 12.6 g/m ² , and the basis weight of ethyl vanillin is about 2.5 g/m ² .

Comparative example 1

As the cigarette paper surrounding the tobacco material, a cigarette to which the cigarette paper having the physical properties of Comparative Example 1 in Table 1 was applied was prepared.

Table 1 classification Example 1 Example 2 Comparative example 1 Tensile strength (kgf) 1.5 1.4 Basis weight (g/m ² ) 46.4 46.0 filler(%) 21.4 22.0 Porosity (CU) 43.0 50.0 Flame retardant (%) 0.8 0.85 Ethyl vanillin addition amount (%) 1.0 0

The cigarettes according to Example 1, Example 2 and Comparative Example 1 are smoking products with a length of about 100 mm in the upstream and downstream directions, a circumference of about 17 mm, and a tar of about 1.0 mg, as described above, and are applicable to the examples 1. The characteristics of each smoking material wrapping paper of Example 2 and Comparative Example 1 are shown in Table 1. In Table 1, the main difference between Example 1 and Example 2 and Comparative Example 1 lies in whether ethyl vanillin is added when preparing smoking material packaging paper, which is suitable for the ethyl vanillin of the cigarette paper according to Example 1. The addition amount is 1% relative to the basis weight of the smoking material wrapping paper, that is, about 0.46 g/m ² .

Experimental example 1: Component analysis of sidestream smoke and mainstream smoke produced during smoking

In order to analyze the components of sidestream smoke and mainstream smoke of the cigarettes of Example 1, Example 2 and Comparative Example 1 of the present invention, the sidestream smoke and mainstream smoke generated when each cigarette is smoked were collected. Each sample was repeated three times for smoke capture, each time capturing 70 mL of sidestream smoke and 20 mL of mainstream smoke. The results of the component analysis based on the average value of the three collection results are shown in Table 2 and Figure 7. In a smoking room with a temperature of about 20°C and a humidity of about 62.5%, an automatic smoking device was used to test cigarettes in accordance with Health Canada (HC) smoking conditions.

Table 2 classification Example 1 Example 2 Comparative example 1 Sidestream smoke (70mL) Ethyl vanillin (ug/cig) 4.6 115.4 1.4 Vanillin (ug/cig) 5.8 2.2 2.3 Raspberry Ketone (ug/cig) 0.0 2.2 0.0 Mainstream smoke (20mL) Ethyl vanillin (ug/cig) 2.5 75.4 0.5 Vanillin (ug/cig) 4.1 2.2 2.0 Raspberry Ketone (ug/cig) 0.0 4.0 0.0

As shown in Table 2 and Figure 7, in the sidestream smoke of the cigarette according to Example 1, about 3.2 times or more ethyl vanillin and 2.5 times or more were detected in the sidestream smoke of the cigarette according to Comparative Example 1. In mainstream smoke, about 5 times ethyl vanillin and 2.5 times more vanillin were detected in mainstream smoke. Raspberry ketone was not detected in both samples, and it is assumed that the ethyl vanillin detected in the sidestream smoke and mainstream smoke of Comparative Example 1 where ethyl vanillin was not added when preparing the smoking material wrapping paper Smoking material parts of cigarettes other than wrapping paper are produced. Through the results, it can be confirmed that ethyl vanillin added when preparing the smoking material wrapping paper surrounding the smoking material portion of the cigarette is transmitted to the outside of the cigarette through mainstream smoke and sidestream smoke when the cigarette is smoked. From this, it is predicted that the sidestream smoke and mainstream smoke generated when the cigarette is smoked according to Example 1 are improved, and the bad tobacco odor generated when smoking is reduced through the increased ethyl vanillin. On the other hand, in the sidestream smoke of the cigarette according to Example 2, about 82 times or more ethylvanillin was detected in the sidestream smoke of the cigarette according to Comparative Example 1, and about 150 times that of the mainstream smoke was detected Of ethyl vanillin. No raspberry ketone was detected in the samples of Example 1 and Comparative Example 1, so it is difficult to compare the value of raspberry ketone, but refer to the ethyl vanillin or vanillin detected in Example 1 and Comparative Example 1. Numerical value, it can be confirmed that in Example 2, raspberry ketones above a significant value were detected. It is predicted that when raspberry ketone components are included in sidestream smoke and mainstream smoke as shown in Example 2, the flavor of raspberry ketone produces sidestream smoke and/or improvement of mainstream smoke or masking effect of tobacco smoke smell. Through the results, it can be confirmed that the fragrance liquid (ie, ethyl vanillin and raspberry ketone, etc.) applied to the inner lining of the cigarette shell is transferred to the cigarette, and when the cigarette is smoked, ethyl vanillin and raspberry ketone permeate Mainstream smoke and sidestream smoke are transferred to the outside of the cigarette. Thereby, the sidestream smoke and mainstream smoke generated when the cigarette according to Example 1 is smoked are improved, and the bad smell of smoke generated when smoking is reduced through the increased ethyl vanillin and newly generated raspberry ketone.

On the other hand, in Example 2, where ethyl vanillin was applied to the inner liner and transferred to cigarette paper, the result was different from Example 1 where ethyl vanillin was applied to the cigarette itself. The value of only increased, and the amount of vanillin was not significantly different from Comparative Example 1.

When comparing the results of Example 2 with Example 1, the sidestream smoke of the cigarette according to Example 2 detected about 25 times more ethyl vanillin than the sidestream smoke of the cigarette according to Comparative Example 1. About 30 times more ethyl vanillin was detected in mainstream smoke. It is predicted from this that, compared with Example 1, the sidestream smoke and mainstream smoke of Example 2 are improved and the tobacco odor reduction effect is more improved.

On the other hand, in Example 2, not only the absolute value is simply increased, but the amount of ethyl vanillin included in the smoke (side stream smoke and mainstream smoke) is also different from the actual amount of ethyl vanillin added. Example 1 is more advantageous. Specifically, the basis weight of ethyl vanillin coated on the inner liner of Example 2 is about 2.5 g/m ² , which is the basis weight of ethyl vanillin directly added to the cigarette paper of Example 1. 0.46g/m ² is about 5.5 times the value. Considering that the detected amount of ethyl vanillin in the sidestream smoke of Example 2 is about 25 times that of Example 1, and the detected amount of ethyl vanillin in the mainstream smoke is about 30 times that of Example 1, it can be confirmed that when the coating is the same When the amount (or the same basis weight, etc.) of ethyl vanillin, the aerosol generation effect of ethyl vanillin in Example 2 is significantly higher than that in Example 1. It is presumed that this is due to the preparation of cigarettes after adding perfume to cigarette paper Loss of fragrance liquid in the process, etc. Or, as shown in Example 2, when the fragrance is applied to the inner liner and then the cigarette is stored in the outer casing of the smoking article, it is presumed that it is similar to the case where the fragrance is directly added to the cigarette paper and stored as shown in Example 1. Compared with the cigarette, it is more uniformly transferred to the components other than the cigarette paper (for example, the smoking material part or the filter, etc.), which is beneficial to the aerosolization of ethyl vanillin during smoking.

Experimental example 2: Sensory evaluation of sidestream smoke and the smell of smoking

In order to confirm the odor reduction effect and the degree of smoking reduction of the sidestream smoke of the cigarettes of Example 1, Example 2 and Comparative Example 1 of the present invention, sensory evaluation was performed. The results are shown in Figures 8 and 9.

Figure 8 shows the evaluation results of the sensory characteristics of sidestream smoke of cigarettes according to Example 1, Example 2 and Comparative Example 1, and Figure 9 shows the smoking taste of cigarettes according to Example 1, Example 2 and Comparative Example 1. The sensory characteristics of the evaluation results.

The sensory characteristics of Figs. 8 and 9 were evaluated on 60 evaluation panel members, and scores were based on a full score of 7 points.

As shown in Figure 8, compared with Comparative Example 1, the smoking article of Example 1 in which ethyl vanillin was added to the smoking material wrapper has an increase in the sweetness of sidestream smoke by approximately 11%, and the unpleasant odor of sidestream smoke A reduction of about 12% and an increase in the containment of sidestream smoke by about 14%, it can be confirmed that the sidestream smoke produced when the cigarettes with ethyl vanillin added to the cigarette paper are smoked as shown in Example 1 does not reduce the smell , On the contrary, improve in a better direction.

In the case of Example 2, it can be confirmed that the sidestream smoke improvement effect is more significant than that of Example 1. Specifically, the sweetness of the sidestream smoke of the cigarette of Example 2 was increased by about 31% compared with Comparative Example 1 (about 18% more than that of Example 1), and the unpleasant odor of the sidestream smoke was comparable to that of Comparative Example 1. The ratio is reduced by approximately 55% (compared to Example 1 by approximately 49%), the effect is significant, and the sidestream smoke tolerance is also increased by approximately 34% compared to Comparative Example 1 (compared to Example 1 by approximately 17%) From this, it can be confirmed that all the sidestream smoke evaluation indicators are improving in the ideal direction.

On the other hand, as shown in Fig. 9, it can be seen that in most of the evaluation indexes, the evaluation results of the sensory characteristics of smoking of the cigarettes of Example 1 and Example 2 are improved compared with Comparative Example 1.

Specifically, compared with Comparative Example 1, the cigarette of Example 1 has improved smoking taste in all evaluation indicators. In particular, it can be confirmed that the taste intensity during smoking increases by about 19% and the swallowing during smoking increases16 %, there is a slight increase in the blending taste in smoking.

In addition, in order to minimize the heterogeneity with the existing tobacco, the experiment was performed with a slightly conservative setting of the physical property values of the smoking material wrapping paper in the smoking product of Example 1 used in the sensory property evaluation of Figs. 8 and 9 However, when the basis weight of the smoking material wrapping paper and the addition amount of ethyl vanillin are increased compared with Example 1, it is predicted that the sidestream smoke improvement effect will exhibit more excellent sensory characteristics.

Compared with Comparative Example 1, the cigarette of Example 2 has a reduction of about 4% in the blending taste during smoking, an increase of about 7% in off-flavor during smoking, but an increase in taste intensity during smoking by approximately 22%, and an increase in swallowing during smoking by approximately 25%. The refreshing of the aftertaste during smoking increased by about 28% or more, so it can be confirmed that the sidestream smoke has been improved, and the overall taste characteristics have also improved in the desired direction.

As described above, according to the smoking article of the embodiment of the present invention and the smoking article shell including the same, the first flavor material such as ethyl vanillin (and the second flavor material such as raspberry ketone) is added to the packaging paper of the smoking material. The fragrance material) can improve the sidestream smoke generated in the smoking article, and at the same time can prevent the possible reduction in smoking taste due to the improvement of the sidestream smoke.
