In some embodiments, the length 230L1 of the tipping wrapper 230 may be approximately 33mm to 37mm. Assuming that the length of the filter 210 for smoking articles is 30 mm, the length 230L2 of the tipping wrapper 230 overlapping the smoking material portion 120 may be approximately 3 mm to 7 mm.

The smoking article 200 may have an elongated rod shape, and its length and diameter may vary. For example, the length of the smoking article 200 may be approximately 45mm to 100mm, and the diameter may be approximately 5mm to 9mm.

However, considering the discoloration issue depending on the basis weight and composition of the smoking material wrapper 120a described above, the smoking material 200 has a total length of about 90 mm to 110 mm (preferably about 100 mm) and has a circumference (or smoking material wrapper ( The width of 120a) is about 14 mm to 20 mm (preferably about 17 mm), the smoking material portion 120 has a length of about 65 mm to 75 mm (preferably about 70 mm), and the length of the first filter 212 (212 L ) Is approximately 10 mm to 20 mm (preferably approximately 15 mm), and the length 214L of the second filter 214 may be approximately 10 mm to 20 mm (preferably approximately 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 are approximately 2.6mm to 3.0. May be 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 are not limited thereto.

The first capsule 212c may be disposed at a position where general smokers hold the smoking article 200 when smoking. Preferably, the first capsule 212c may be positioned to be approximately 18mm to 27mm apart from the downstream end of the second filter 214, that is, the downstream end of the smoking article 200 in the upstream direction. As a more specific example, the center point of the first capsule 212c is positioned to be approximately 21mm to 24mm apart from the downstream end of the smoking article 200 in the upstream direction, and the upstream end of the first capsule 212c is the downstream of the smoking article 200 It is positioned so as to be spaced approximately 22.5mm to 25.5mm in the upstream direction from the end, and the downstream end of the first capsule 212c may be positioned to be approximately 19.5mm to 22.5mm apart in the upstream direction from the downstream end of the smoking article 200.

A second perforated area 214P may be formed in the wrappers 214a, 216, and 230 positioned at a portion covering the second filter 214. In the second perforated region 214P, as shown in FIG. 3, the tipping wrapper 230 is double perforated, that is, a plurality of first holes 214P1 and first holes 214P1 formed along the outer circumferential surface of the tipping wrapper 230. A plurality of second holes 214P2 formed along the outer peripheral surface of) may be provided, but the present invention is not limited thereto. For example, unlike in FIG. 3, only one of the plurality of first holes 214P1 and the plurality of second holes 214P2 may be provided (single perforation) in the second perforated region 214P, or In addition to the plurality of first holes 214P1 and the plurality of second holes 214P2, additional holes may be further provided.

Each of the plurality of first holes 214P1 and the plurality of second holes 214P2 may include, for example, 4 to 10 holes, and the holes are constant along the outer circumferential surface of the tipping wrapper 230. It may be formed to be spaced apart at intervals, but is not limited thereto. The diameter of each of the holes may be approximately 0.02mm to 0.08mm (eg, 0.05mm), but is not limited thereto.

The holes may be formed by an on-line perforation method, that is, a method of perforating a filter portion after manufacturing a cigarette using a tipping wrapper that is not perforated. The online perforation may be performed using a laser, but is not limited thereto. As the holes are drilled online in this way, the holes are not only the tipping wrapper 230 but also the coupling wrapper 216, the second wrapper 214, and further to a partial area outside the second filter 214 as shown in FIG. It may be extended, and thus external air may flow from the outside to the inside of the second filter 214 through the second perforated region 214P. External air introduced through the second perforations 214P may be mixed with mainstream smoke and transmitted 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 approximately 0.5mm to 1.5mm. In other words, the plurality of first holes 214P1 may be positioned to be approximately 0.5 mm to 1.5 mm apart from the plurality of second holes 214P2 in the upstream direction.

In some embodiments, the plurality of first holes 214P1 are positioned so as to be spaced approximately 22mm to 25mm (214P_TEd) from the upstream end of the tipping wrapper 230, and the plurality of second holes 214P2 are positioned to be a second filter 214 ) Can be positioned to be approximately 9mm to 12mm apart (214P_MEd) from the downstream end.

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, as shown in FIG. 3. .

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

In FIG. 4, the same reference numerals as in FIGS. 1 to 3 denote the same members, and redundant descriptions thereof are omitted here for the sake of simplicity.

Referring to FIG. 4, the smoking article 300 may include a smoking material part 120, a smoking material wrapper 120a, a filter for smoking articles 210 and a tipping wrapper 330, and a filter for smoking articles ( 210) includes a first filter 212, a second filter 214, a first wrapper 212a, a second wrapper 214a, a first capsule 212c, a second capsule 214c, and a combination wrapper 216. It may include.

A first perforated area 312P may be formed in the tipping wrapper 330 of the smoking article 300. In the first perforated area 312P, as shown in FIG. 4, the tipping wrapper 130 is double perforated, that is, a plurality of first holes 312P1 and the first holes 312P1 formed along the outer peripheral surface of the tipping wrapper 330. A plurality of second holes 312P2 formed along the outer peripheral surface of) may be provided, but is not limited thereto. For example, unlike in FIG. 4, only one of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be provided (single perforation) in the first perforated area 312P, or In addition to the plurality of first holes 312P1 and the plurality of second holes 312P2, additional holes may be further provided.

Each of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be formed to be spaced apart at regular intervals along the outer peripheral surface of the tipping wrapper 130, but is not limited thereto.

The holes may be formed by an off-line perforation method, that is, a method of manufacturing a cigarette using the tipping wrapper 330 pierced in the tipping wrapper 330 in advance. The off-line drilling may be performed using a laser, but is not limited thereto.

Since the plurality of first holes 312P1 and/or the plurality of second holes 312P2 are formed, the porosity of the tipping wrapper 330 in the first perforated area 312P may be approximately 190 CU to 210 CU. In other words, the plurality of first holes 312P1 and/or the plurality of second holes 312P2 may be drilled to a size such that the porosity of the tipping wrapper 330 is approximately 190 CU to 210 CU. This means that if the tipping wrapper 330 is punched so that the porosity is less than about 190 CU, the practical benefit is less in terms of the effect of increasing the transfer rate of the capsule contents, and if the tipping wrapper 330 is punched so that the porosity is about 210 CU or more, the first punching This is because mainstream smoke may leak through the area 312P.

As such, the holes are drilled off-line, and the porosity of the tipping wrapper 330 in the first drilled region 312P is approximately 190CU to 210CU, and the holes are formed only in the tipping wrapper 330 as shown in FIG. It does not extend to the coupling wrapper 216 and the first wrapper 212a. Accordingly, the first capsule 212c is crushed by the smoker so that the capsule contents discharged to the outside of the first capsule 212c can be better transferred to the smoker's hand, and the holes are combined with the wrapper 216 ) And by not extending to the first wrapper 212a, it is possible to prevent the mainstream smoke from leaking out 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 approximately 1mm to 3mm. In other words, the plurality of first holes 312P1 may be positioned to be approximately 1mm to 3mm apart in the upstream direction from the plurality of second holes 312P2.

In some embodiments, a separation distance 312Pw of the plurality of first holes 312P1 and the plurality of second holes 312P2 of the first puncture region 312P is a plurality of first holes of the second puncture region 214P. It may be about 1.5 to 3 times (eg, 2 times) of the separation distance 214Pw between the holes 214P1 and the plurality of second holes 214P2. For example, the separation distance 312Pw may be approximately 2mm, and the separation distance 214Pw may be approximately 1mm, but the present invention is not limited thereto.

In some embodiments, the plurality of first holes 312P1 are positioned to be spaced apart from the upstream end of the tipping wrapper 330 by approximately 10 mm to 13 mm (312P_TEd), and the plurality of second holes 312P2 may include a second filter 214 ) May be positioned to be approximately 20mm to 23mm apart (312P_MEd) from the downstream end.

In some embodiments, the separation distance Per_D between the plurality of second holes 312P2 of the first puncture area 312P and the plurality of first holes 214P1 of the second puncture area 312P is approximately 9mm to 10mm. Can be

On the other hand, unlike the plurality of first holes 214P1 and the plurality of second holes 214P2 of the second puncture region 214P, the plurality of first holes 312P1 and the plurality of second holes in the first puncture region 312P 2 The holes 312P2 are located in an area overlapping with the first capsule 212c as shown in FIG. 4, so that the first capsule 212c is crushed by the smoker, and the capsule contents are discharged to the outside of the first capsule 212c. The liquid can be better delivered to the smoker's hands.

As described above, in the smoking articles 100, 200, and 300 according to the embodiments of the present invention, a first fragrance material such as ethyl vanillin (and a second fragrance material such as raspberry ketone) is added to the smoking material reper 120a. The included fragrance is applied, and further, the first filter 212 may include a first capsule 212c containing a fragrance capable of reducing the smoker's hand odor (and breath), and the second filter 214 ) May include a second capsule (214c) containing a fragrance capable of reducing the smoker's bad breath, reducing odors that may occur due to smoking (such as smoke, hand, and bad breath) At the same time, it is possible to prevent deterioration of the taste when smoking.

On the other hand, adding a flavoring material including a first flavoring material such as ethyl vanillin (and a second flavoring material such as raspberry ketone) to the smoking material wrapper may be performed in various ways. For example, the fragrance may be added directly to the smoking material wrapper 120a described with reference to FIGS. 1 to 4 before manufacturing the smoking article, and then applied to the cigarette. In addition, the fragrance may be added to the smoking article case in which the manufactured smoking articles are accommodated after the smoking article is manufactured and transferred to the smoking article. Hereinafter, a smoking article case according to another embodiment of the present invention may be in detail. Explain.

FIG. 5 is a diagram showing a schematic configuration of a smoking article case according to some embodiments of the present invention, and FIG. 6 is a diagram illustrating an inner liner included in the smoking article case in a plan view.

5 and 6, the smoking article case 1000 includes a case body 1100 in which smoking articles 100 are accommodated, and smoking between the smoking articles 100 and the case body 1100 to be stored. It may include an inner liner 1200 disposed to surround the articles 100.

The case body 1100 is connected to be folded to the upper and rear ends of the case lower body 1110 and the case lower body 1110 having an open upper portion and a space formed therein so that smoking articles 100 can be accommodated. It may include a case upper body 1120 to open and close the upper part of the body 1110.

The inner liner 1200 more stably protects the smoking articles within the case body 1100 and prevents the smoking articles 100 from being easily exposed to the outside, so that the smoking articles 100 are at least one side, preferably Smoking articles 100 may be arranged to wrap around. For example, the inner liner 1200 may be folded along the inner liner fold lines 1200f shown in FIG. 6 to wrap the smoking articles 100 in all directions.

In the inner liner 1200, the inner liner 1200a in the upper front area can be easily separated and removed from the inner liner 1200b in the lower front area so that the smoker can easily take out the smoking article 100. 1200p) may be included.

In order to transfer the fragrance component to the smoking articles 100 stored in the smoking article case 1000, a fragrance composition may be applied to at least a portion of the inner liner 1200.

In some embodiments, the fragrance composition may be applied only to one side of the inner liner 1200 and may not be applied to the other side opposite to the one side. More specifically, the fragrance composition is applied only to one side of the inner liner 1200 in contact with the smoking articles 100, and the inner side of the case body 1100 among both sides of the inner liner 1200 It may not be applied to the other side in contact. On the other hand, in order to minimize the scent composition transferred only to the smoking articles 100 and to minimize leakage to the case body 1100 direction or the outer area of the case body 1100, the other side of the inner liner 1200 Foil or the like may be coated or oil-resistant.

In some embodiments, the fragrance applied to the inner liner 1200 may include a first fragrance material selected from vanillin, ethylvanillin, and ethylvanillin glucoside, and as materials other than the first fragrance material, raspberry ketone, menthol, Methoxy acetophenone, gamma undikelactone, methyl anthranilate, cinnamic acid, myristic acid, anise oil, lemon oil, and at least one second fragrance material selected from orange oil may be included. For example, the perfume composition may have a composition of 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 ethyl alcohol based on the total weight of the perfume composition.

In some embodiments, the total length (1200L) of the inner liner 1200 included in one smoking article case 1000 is approximately 220mm to 230mm (eg, 227mm), and the width 1200W is approximately 65mm to 75mm (For example, 70mm), and the total amount of perfume applied to the inner liner 1200 is about 200 mg, of which ethyl vanillin is about 40 mg, raspberry ketone is about 10 mg, menthol is about 60 mg, and ethyl alcohol is about 90 mg Can be Assuming that the perfume composition applied to the inner liner 1200 is transferred to the 20 smoking articles 100 stored in the smoking article case 1000, about 2 mg of ethyl vanillin and about 2 mg of raspberry ketone are contained in one cigarette. 0.5mg, menthol may contain about 3mg. With respect to the weight of one cigarette, about 0.6% by weight of ethyl vanillin, about 0.15% by weight of raspberry ketone, and about 0.9% by weight of menthol may be included in one cigarette.

Meanwhile, the length and width of the inner liner 1200, the total amount of perfume applied to the inner liner 1200, and the like are numerical values as an example and are not limited thereto. The total amount of perfume (or the amount of ethyl vanillin, etc.) applied to the inner liner 1200 may be determined according to the area of the inner liner 1200. As an example, the total length (1200L) of the inner liner 1200 may be approximately 150mm to 160mm (eg, 155mm), and the width (1200W) may be approximately 110mm to 120mm (eg, 114.5mm). The total amount of perfume applied to the inner liner 1200 may be about 223.4 mg.

In some embodiments, the basis weight of the perfume applied to the inner liner 1200 may be approximately 1 g/m ² to 20 g/m ² , preferably approximately 10 g/m ² to 15 g/m ² . In addition, the basis weight of ethyl vanillin applied to the inner liner may be about 0.2 g/m ² to 4 g/m ² , preferably about 2 g/m ² to 3 g/m ² . In addition, the basis weight of the raspberry ketone applied to the inner liner may be about 0.05 g/m ² to 1 g/m ² , preferably 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 about 3 g/m ² to 4.5 g/m ² .

When the fragrance is applied to the inner liner 1200 included in the smoking article case 1000 as described above, the first fragrance material (and the second fragrance material) is transferred to the smoking items 100, It is possible to reduce the smell of cigarettes by masking the sidestream smoke generated during smoking of the field 100. The inner liner 1200 to which perfume is applied may be used with the smoking articles to which the perfumed cigarette paper described with reference to FIGS. 1 to 4 is applied, but is not limited thereto, and the smoking article to which the perfumed cigarette paper is applied It can also be used with For example, the above-described perfume is applied to the inner liner 1200 of the smoking article case 1000, and the smoking articles included in the smoking article case 1000 may be smoking articles to which no perfume is added.

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

Example 1

For Examples, after removing the cigarette paper surrounding the tobacco material of the cigarette prepared for testing, a cigarette using the cigarette paper having the physical properties of Example 1 in Table 1 was prepared.

Example 2

After manufacturing a cigarette to which the cigarette paper having the physical properties of Comparative Example 1 was applied, the manufactured cigarettes were stored in a smoking article case in which an inner liner to which the perfume composition described with reference to FIGS. 5 to 6 was applied, and then stored for about 2 months. Kept. The smoking article case containing cigarettes was stored in a conditioning room with a temperature of approximately 22°C and a humidity of approximately 62.5%.

The length of the inner liner is about 227 mm and the width is about 70 mm, and the inner liner fragrance is evenly applied to only one side of the inner liner that contacts cigarettes, and the other side that contacts the inner side of the case body of the smoking article case. Was not applied to. Aluminum foil was coated on the other side in contact with the inner side of the case body.

The total amount of the inner liner fragrance evenly applied to the inner liner is about 200 mg, and the inner liner fragrance is about 20% by weight of ethyl vanillin (about 40mg), about 5% by weight of raspberry ketone (about 10mg), about menthol It had a composition of 30% by weight (about 60 mg), and about 45% by weight of ethyl alcohol (about 90 mg). The basis weight of the hyangaek applied to the inner liner is about 12.6g / m ^2, the basis weight of ethyl vanillin is about 2.5g / m ^2.

Comparative Example 1

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

division	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
Supporting agent (%)	0.8	0.85
Addition of ethyl vanillin (%)	1.0	0

Cigarettes according to Examples 1 to 2 and Comparative Example 1 are all smoking articles having a length of about 100 mm in an upstream and downstream direction, a circumference of about 17 mm, and a tar content of about 1.0 mg, as described above, Examples 1 to 2 and The characteristics of the smoking material wrapper applied to each of Comparative Example 1 are shown in Table 1. The main difference between Example 1 compared to Example 2 and Comparative Example 1 in Table 1 is whether ethylvanillin is added when preparing a smoking material wrapper. As for whether or not, ethyl vanillin applied to the cigarette paper according to Example 1 was added with about 0.46 g/m ^{2, which} is 1% of the basis weight of the smoking material wrapper.

Experimental Example 1: Analysis of components of sidestream smoke and mainstream smoke generated during smoking

In order to analyze the components of the cigarettes according to Examples 1 to 2 and Comparative Example 1 of the present invention, the sidestream smoke and the mainstream smoke generated during smoking of each of the cigarettes were collected. Smoke collection was repeated three times for each sample, and 70 mL of sidestream smoke and 20 mL of mainstream smoke were collected per each time. The component analysis results based on the average value of the three collection results are shown in Table 2 and FIG. 7. Cigarettes were tested according to HC (Health Canada) smoking conditions using an automatic smoking device in a smoking room with a temperature of approximately 20°C and a humidity of approximately 62.5%.

division		Example 1	Example 2	Comparative Example 1
Bulyu lead (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 FIG. 7, in the class smoke of the cigarette according to Example 1, about 3.2 times more ethyl vanillin and 2.5 times more vanillin were detected compared to the class smoke of the cigarette according to Comparative Example 1, and about 5 times more ethyl vanillin and Vanillin of 2.5 times or more was detected. In the case of raspberry ketone, it was not detected in both samples, and ethyl vanillin detected in the side smoke and mainstream smoke of Comparative Example 1 in which ethyl vanillin was not added during the manufacture of the smoking material wrapper was generated from the smoking material part of cigarettes other than the smoking material wrapper. I guess it was done. Through the above results, it was confirmed that the ethyl vanillin added during the manufacture of the smoking material wrapper surrounding the smoking material part of the cigarette was transferred to the outside of the cigarette through mainstream smoke and sidestream smoke when smoking the cigarette. Through this, it is expected that the sidestream smoke and mainstream smoke generated when smoking the cigarette according to Example 1 are modified, and the negative cigarette odor generated when smoking is reduced by the increased ethyl vanillin. On the other hand, the sidestream smoke of the cigarette according to Example 2 is expected to be reduced. Ethyl vanillin was detected at about 82 times more than that of the cigarette according to Comparative Example 1, and about 150 times more ethyl vanillin was detected in mainstream smoke. In the case of raspberry ketone, it was not detected in both Example 1 and Comparative Example 1, so numerical comparison was difficult, but when referring to the levels of ethyl vanillin or vanillin detected in Example 1 and Comparative Example 1, the raspberry ketone detected in Example 2 Is confirmed to be detected above a significant value. When the raspberry ketone component is included in the secondary smoke and mainstream smoke as in Example 2, it is expected that the modification of the secondary smoke and/or mainstream smoke or the masking effect of the cigarette smoke odor will occur even by the flavor of the raspberry ketone. The perfume (i.e., ethyl vanillin and raspberry ketone, etc.) applied to the inner liner was transferred to the cigarette, and it was confirmed that the ethyl vanillin and raspberry ketone were transferred to the outside of the cigarette through mainstream smoke and sidestream smoke when smoking such a cigarette. Through this, it is expected that sidestream smoke and mainstream smoke generated during smoking of the cigarette according to Example 1 will be modified, and negative cigarette odors generated during smoking due to increased ethyl vanillin and newly generated raspberry ketone will be reduced.

On the other hand, in Example 2 in which ethyl vanillin was applied to the inner liner and transferred to the cigarette paper, unlike the result in Example 1 in which ethyl vanillin was applied to the cigarette paper itself, only the level of ethyl vanillin was increased, and the amount of vanillin was compared. There was no significant difference from Example 1.

When comparing the results in Example 2 with Example 1, about 25 times or more of ethyl vanillin was detected in the class smoke of the cigarette according to Example 2 compared to the class smoke of the cigarette according to Comparative Example 1, and about 30 times more ethyl Vanillin was detected. Through this, it is expected that the effect of reforming sidestream smoke and mainstream smoke in Example 2 and reducing tobacco odor in Example 2 will increase than in Example 1.

On the other hand, in Example 2, it was confirmed that not only the absolute value increased, but also the amount of ethyl vanillin contained in smoke (side-like smoke and mainstream smoke) relative to the amount of ethyl vanillin added was advantageous compared to Example 1. Specifically, the basis weight of ethyl vanillin applied to the inner liner of Example 2 is approximately 2.5 g / m ² , which is about 5.5 times the basis weight of ethyl vanillin added directly to the cigarette paper of Example 1 0.46 g / m ² It's a shame. Considering that the detection amount of ethyl vanillin in Example 2 is about 25 times that of Example 1 and the detection amount of ethyl vanillin in mainstream smoke is about 30 times, an aerosol of ethyl vanillin is generated when the same amount (or the same basis weight, etc.) It can be seen that the effect is much higher in Example 2 than in Example 1, and this is estimated to be due to the loss of flavor in the manufacturing process into a cigarette after adding the flavor to the cigarette paper. Alternatively, when storing the cigarette in a smoking article case after applying the fragrance to the inner liner as in Example 2, components other than the cigarette paper of the cigarette (for example, smoking It is presumed to be more evenly transferred to the material part or filter, etc., which is advantageous for the aerosolization of ethyl vanillin during smoking.

Experimental Example 2: Sensory evaluation of smoking taste during smoking and smoking

Sensory evaluation was performed to confirm the odor reduction effect and the degree of inhibition of smoking taste of cigarettes according to Examples 1 to 2 and Comparative Example 1 of the present invention, and the results are shown in FIGS. 8 and 9.

FIG. 8 is a result of evaluating sensory properties of cigarettes according to Examples 1 to 2 and Comparative Example 1, and FIG. 9 is a result of evaluating sensory characteristics of smoking taste of cigarettes according to Examples 1 to 2 and Comparative Example 1.

The sensory evaluation of FIGS. 8 and 9 was performed on 60 evaluation panel members, based on a total of 7 points.

As shown in FIG. 8, the smoking article content of the smoking article of Example 1, in which ethyl vanillin was added to the smoking material wrapper, increased by about 11% compared to Comparative Example 1, the unpleasant odor decreased by about 12%, and the acceptance rate of the smoked smoke was It was found to have increased by approximately 14%, and it was confirmed that the sidestream smoke generated when smoking the cigarette containing ethyl vanillin added to the cigarette paper as in Example 1 was modified in a rather desirable direction without inhibiting the taste of smoking.

In the case of Example 2, it was confirmed that the above-described classy lead reforming effect was more pronounced compared to Example 1. Specifically, the amount of cigarette smoke of Example 2 increased by about 31% (about 18% compared to Example 1) compared to Comparative Example 1, and the unpleasant odor of the cigarette of Example 2 increased by about 55% (about 49% compared to Example 1). ), the effect was remarkably decreased, and the acceptance rate of the classmates was also increased by about 34% compared to Comparative Example 1 (approximately 17% compared to Example 1), and improvement in a positive direction was confirmed in all the classifiers evaluation indicators.

On the other hand, as shown in FIG. 9, the evaluation results of the sensory properties for smoking taste of cigarettes of Examples 1 and 2 were preferably improved compared to Comparative Example 1 in most of the evaluation indexes.

Specifically, in the case of the cigarette of Example 1, compared to Comparative Example 1, it was found that smoking taste improved in a desirable direction in all evaluation indicators, in particular, taste intensity during smoking increased by about 19%, and throat during smoking increased by 16%, and smoking It can be seen that the medium harmony also slightly increased.

Furthermore, the smoking article of Example 1 used in the sensory evaluation of FIGS. 8 and 9 was tested by setting the physical property value of the smoking material wrapper somewhat conservatively in order to minimize the feeling of heterogeneity with the current cigarette, but the basis weight of the smoking material wrapper and When the addition amount of ethyl vanillin is increased compared to Example 1, it is expected that more excellent sensory properties will come out in terms of the effect of reforming the sidestream smoke.

In the case of the cigarette of Example 2, compared to Comparative Example 1, the harmony taste during smoking decreased by about 4% and the taste and taste during smoking increased by about 7%, but the taste intensity during smoking was about 22%, the throat while smoking was about 25%, smoking The neatness of the middle aftertaste increased by about 28% or more, and it could be confirmed that the taste characteristics were also preferably modified overall at the same time as the sidestream modification.

As described above, according to the smoking article and the smoking article case including the same according to an embodiment of the present invention, a fragrance including a first fragrance material such as ethyl vanillin (and a second fragrance material such as raspberry ketone) in a smoking material wrapper is By adding it, it is possible to modify sidestream smoke generated in smoking articles, and at the same time, it is possible to prevent deterioration in smoking taste that may occur due to sidestream smoke modification.

Those of ordinary skill in the technical field related to the present embodiment will appreciate that it may be implemented in a modified form without departing from the essential characteristics of the above-described description. Therefore, the disclosed methods should be considered from an explanatory point of view rather than a limiting point of view. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
