Figure 1 is a diagram showing the general structure of a filter for smoking articles according to some embodiments of the present invention.

Referring to fig. 1, a filter 110 for a smoking article may comprise a first filter 112, a second filter 114, a first wrapper 112a, a second wrapper 114a, a first capsule 112c, a second capsule 114c and a combined wrapper 116.

The filter 110 for the smoking article may be an area arranged downstream of the smoking material portion and passing before a user draws aerosol material generated in the smoking material portion.

The first and second filters 112, 114 may be formed of various materials, for example, the first and second filters 112, 114 may be cellulose acetate filters. The first filter 112 and the second filter 114 may have the same specifications and composition, but the invention is not limited thereto. For example, the first filter 112 is a cellulose acetate filter that is flavored with no flavorant material, and the second filter 114 is a filter that is flavored with a flavorant material, such as a Transfer Jet Nozzle System (TJNS) filter.

In some embodiments, the respective lengths of the first and second filters 112 and 114 may be suitably employed in the range of 4 to 30mm, and the respective diameters of the first and second filters 112 and 114 may be suitably employed in the range of 5 to 8mm, but the present invention is not limited thereto. Preferably, the respective lengths of the first and second filters 112 and 114 may be about 15mm, and the respective diameters of the first and second filters 112 and 114 may be about 5.4mm.

In some embodiments, first filter 112 and/or second filter 114 may be tubular structures that include a cavity therein. In this case, the diameter of the cavity included in the first filter 112 and/or the second filter 114 may take a suitable diameter in the range of 2mm to 4.5mm, but the present invention is not limited thereto. In addition, the first filter 112 and/or the second filter 114 may be made by inserting structures such as membranes, tubes, with the same or different materials inside (e.g., cavities).

The hardness of the first filter 112 and/or the second filter 114 may be adjusted by adjusting the content of the plasticizer when manufacturing the first filter 112 and/or the second filter 114.

Triacetin (triacetin) may be used as the plasticizer, and the content of triacetin may be 5 to 15 weight percent with respect to the total weight of the first and second filters 112 and 114, but the type and content of the plasticizer are not limited thereto and may be appropriately adjusted as needed.

The first filter 112 includes a first capsule 112c therein, and the second filter 114 includes a second capsule 114c therein. The first capsule 112c and/or the second capsule 114c may have a structure in which a content solution containing a perfume is surrounded with a film, for example, the first capsule 112c and/or the second capsule 114c may have a spherical shape or a cylindrical shape.

The material forming the film of the first capsule 112c and/or the second capsule 114c may be starch and/or a gelling agent. For example, gellan gum or gelatin may be used as the gelling agent. In addition, a gelling aid may further serve as a material for forming a film of the first capsule 112c and/or the second capsule 114c. Here, for example, calcium chloride may be used as a gelling aid. In addition, a plasticizer may be further used as a material for forming the film of the first capsule 112c and/or the second capsule 114c. Here, glycerin and/or sorbitol may be used as the plasticizer. Also, the colorant may further serve as a material forming the film of the first capsule 112c and/or the second capsule 114c.

The content solution in the first capsule 112c and/or the second capsule 114c may include flavors such as menthol and essential oils of plants.

In some embodiments, each of the first capsule 112c and the second capsule 114c may include a flavor selected from the group consisting of mango, wine, mogerto, apple, orange, strawberry, green apple, apple and sweet mango flavors. Here, the first and second capsules 112c and 114c may include different kinds of flavors, but the present invention is not limited thereto. For example, the first capsule 112c may include a mango-flavored flavor, and the second capsule 114c may include an apple mint-flavored flavor.

On the other hand, in order to maximize the speed of transfer of the perfume contained in the first capsules 112c to the fingers through the wrappers 112a, 116, 130 after the first capsules 112c are ruptured, the content of the perfume contained in the first capsules 112c may be about 20 to 50 weight percent with respect to the total weight of the capsules, and the perfume may be a highly volatile fruit-based flavor that can be easily released to the outside of the wrappers.

In some embodiments, as the solvent for the flavor of the content solution contained in the first capsule 112c and/or the second capsule 114c, for example, medium chain fatty acid triglyceride (MCTG) may be used. In addition, the content solution may contain other additives such as a pigment, an emulsifier, a thickener, and the like.

The first and second filters 112, 114 may be wrapped by wrappers 112a, 114a, 116. More specifically, the first filter 112 may be wrapped with a first wrapper 112a, the second filter 114 may be wrapped with a second wrapper 114a, and the first filter 112 and the second filter may be jointly wrapped with a joint wrapper 116. In other words, the first filter 112 wrapped with the first wrapper 112a and the second filter 114 wrapped with the second wrapper 114a are further wrapped with the combining wrapper 116 and physically combined.

The first wrapper 112a and the joint wrapper 116 may be made of general roll paper without oil-resistant treatment. For example, the first wrapper 112a and the combined wrapper 116 may be porous roll paper or non-porous roll paper. For example, the first wrapper 112a and the combined wrapper 116 may be a non-porous roll paper having a porosity of about 10CU to 20CU in units of International Tobacco Scientific Research Relative to Tobacco, or a porous roll paper having a porosity equal to or greater than about 6500CU (e.g., 24000 CU).

The same roll paper may be applied to the first wrapper 112a and the joint wrapper 116, but the present invention is not limited thereto, and roll paper having different characteristics may be applied. For example, one of the first wrapper 112a and the combining wrapper 116 may be a porous roll paper, and the other wrapper may be a non-porous roll paper.

The first wrapper 112a and the joint wrapper 116 may be made of roll paper that is not subjected to oil resistance treatment. That is, the first wrapper 112a and the joint wrapper 116 may be made of roll paper which is not subjected to oil-resistant treatment, so that the capsule content solution which is ruptured by the smoker to be released to the outside of the first capsule 112c is transferred to the hand of the smoker through the first wrapper 112a.

The second wrapping paper 114a may be made of roll paper having oil resistance. That is, the second wrapper 114a may be made of oil-resistant roll paper to prevent the capsule content solution ruptured by the smoker to be released outside the second capsule 114c from passing through the second wrapper 114a. In some embodiments, the inner side of the second wrapper 114a may further include aluminum foil.

As shown in figure 2, the above-described filter 110 for smoking articles is arranged downstream of the smoking material portion 120 to act as a filter through which aerosol material generated in the smoking material portion 120 passes before being drawn by the user. Next, the smoking article 100 including the filter 110 for a smoking article will be described in detail.

Fig. 2 is a view showing a schematic structure of a smoking article employing a filter for a smoking article according to some embodiments of the present invention, and fig. 3 is a central axial direction partial sectional view of a smoking article according to some embodiments of the present invention.

In fig. 2 and 3, the same reference numerals as in fig. 1 denote the same members, and a repetitive description will be omitted herein for convenience of description.

Referring to figures 2 and 3 in a mutual way, the smoking article 100 may comprise a smoking material portion 120, a smoking material wrapper 120a, a filter 110 for the smoking article and a tipping wrapper 130. The filter 110 for a smoking article may comprise a first filter 112, a second filter 114, a first wrapper 112a, a second wrapper 114a, a first capsule 112c, a second capsule 114c and a combined wrapper 116.

The smoking material portion 120 may contain an aerosol generating substance. For example, the smoking material portion 120 may include tobacco cut filler.

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

The smoking material portion 120 may have an elongated rod shape and may vary in length and diameter. For example, the smoking material portion 120 may be about 15mm to 70mm in length and about 5mm to 9mm in diameter.

In some embodiments, the smoking material portion 120 may include other additive materials such as flavorants, humectants, and/or acetate compounds. For example, flavoring agents may include licorice, sucrose, fructose syrup, isosweet (isosweet), cocoa, lavender, cinnamon, cardamom, celery, fenugreek, casaria, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, iland, salvia, spearmint, ginger, coriander, coffee, or the like. Also, the humectant may include glycerin or propylene glycol, and the like.

In some embodiments, the smoking material portion 120 may include reconstituted tobacco material formed into a bulk shape, such as a rod, by mixing tobacco material with a solvent and various additives after grinding it, followed by drying to form a sheet, which is processed to form the tobacco material into a rod or the like. For example, the smoking material portion 120 includes a plurality of tobacco material filaments, one of which is about 10mm to 14mm (e.g., 12 mm) in length, about 0.8mm to 1.2mm (e.g., 1 mm) in width, and about 0.08mm to 0.12mm (e.g., 0.1 mm) in thickness, although the invention is not limited thereto.

By making the smoking material part 120 include a plurality of strands of material that are processed in the shape of a wide tobacco sheet, the density of the tobacco material filled in the smoking material part 120 can be increased, so that the aerosol generation amount can be increased, and the smoking characteristics of the smoking material part 120 can be improved.

The smoking material portion 120 may be wrapped by a smoking material wrapper 120 a. The smoking material wrapper 120a may be made of the same roll paper as the first wrapper 112a or the combined wrapper 116 described with reference to fig. 1, but the present invention is not limited thereto.

The smoking material portion 120 wrapped by the smoking material wrapper 120a and the filters 112, 114 wrapped by the tipping wrapper 116 may be joined and wrapped by the tipping wrapper 130. That is, the tipping wrapper 130 may surround at least a portion (e.g. a downstream portion region) of the smoking material wrapper 120a and the periphery of the tipping wrapper 116. In other words, at least a portion of the smoking material portion 120 and the filters 112, 114 may be further wrapped and physically bonded by tipping wrapper 130.

In some embodiments, the length 130L1 of the tipping wrapper 130 may be about 33mm to 37mm. Where the length of the filter 110 for a smoking article is 30mm, the length 130L2 of the tipping wrapper 130 which overlaps the smoking material portion 120 may be about 3mm to 7mm.

The tipping wrapper 130 may be made from plain paper roll. The tipping wrapper 130 may be a porous or non-porous roll paper, for example. For example, the tipping wrapper 130 may be a non-porous roll paper having a porosity of about 10CU to 20CU, or a porous roll paper having a porosity equal to or greater than about 6500CU (e.g., 24000 CU).

The tipping wrapper 130 may be made from the same web of paper as the first wrapper 112a or the tipping wrapper 116, although the invention is not limited thereto. For example, the tipping wrapper 130 may be a non-porous roll of paper, and the first wrapper 112a and/or the combined wrapper 116 may be a porous roll of paper.

The tipping wrapper 130 may be made from roll paper that has not been subjected to oil resistance treatment. That is, the tipping wrapper 130 may be made of roll paper that is not subjected to oil-resistant treatment, so that the solution of capsule contents that is ruptured by the smoker to be released outside the first capsule 112a is transferred to the smoker's hand through the first wrapper 112a, the bonding wrapper 116, and the tipping wrapper 130. In addition, the tipping paper 130 may be coated with a sweetener such as sucralose, citric acid, or the like.

In some embodiments, a predetermined material may be added to the tipping wrapper 130. An example of the predetermined material may be silicon, but the present invention is not limited thereto. For example, silicon has characteristics such as heat resistance with little change in temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency to water, electrical insulation, and the like. However, any material having the above characteristics may be coated or coated on the tipping wrapper 130 without limitation, even if it is not silicon.

The tipping wrapper 130 may prevent burning of the filter 110 for the smoking article. For example, when the smoking material portion 120 is burned to a portion adjacent to the filter 110 for smoking articles, even the filter 110 for smoking articles may be burned. Even in this case, since the tipping wrapper 130 comprises a non-combustible material, combustion of the filter 110 for a smoking article can be prevented.

The smoking article 100 may have the shape of an elongated rod, and its length and diameter may vary.

In some embodiments, the smoking article 100 may be about 45mm to 100mm in length, about 4mm to 6mm in diameter (e.g., about 5.4 mm), and about 14mm to 19mm in circumference (e.g., about 17 mm). The length of the smoking material portion 120 may be about 70mm, the length 112L of the first filter 112 may be about 15mm, and the length 114L of the second filter 114 may be about 15mm, but the present invention is not limited thereto.

In some other embodiments, the smoking article 100 may have a diameter of about 7mm to 9mm (e.g., about 7.8 mm) and a circumference of about 22.5mm to 26.5mm (e.g., about 24.5 mm).

The first and second capsules 112c, 114c may have a spherical shape, and the diameter 112c _, d of the first capsule 112c and the diameter 114c _, d of the second capsule 114c may be about 2.6mm to 3.0mm. In some embodiments, the diameter 112c _, d of the first capsule 112c and the diameter 114c _, d of the second capsule 114c may be the same, although the invention is not limited thereto.

The first capsule 112c may be disposed in a position to grasp the smoking article 100 when a normal smoker takes a puff on the cigarette. Preferably, the first capsule 112c may be located at the downstream end of the second filter 114, i.e. a position spaced about 18mm to 27mm in the upstream direction from the downstream end of the smoking article 100. As a more specific example, the center point of the first capsule 112c may be located at a position spaced about 21mm to 24mm from the downstream end of the smoking article 100 toward the upstream direction, the upstream end of the first capsule 112c may be located at a position spaced about 22.5mm to 25.5mm from the downstream end of the smoking article 100 toward the upstream direction, and the downstream end of the first capsule 112c may be located at a position spaced about 19.5mm to 22.5mm from the downstream end of the smoking article 100 toward the upstream direction.

The first capsule 112c and the second capsule 114c may have a separation distance Cap _ D of about 10mm to 14 mm. In other words, the first capsule 112c may be located at a position spaced about 10mm to 14mm from the second capsule 114c toward the upstream direction.

The second perforated region 114P may be formed at the wrapper 114a, 116, 130 at a portion covering the second filter 114. As shown in fig. 3, the second perforated region 114P may have double perforations, i.e., may have a plurality of first holes 114P1 formed along the outer circumferential surface of the tipping wrapper 130 and a plurality of second holes 114P2 formed along the outer circumferential surface of the tipping wrapper 130 downstream of the first holes 114P1, but the present invention is not limited thereto. For example, unlike what is shown in fig. 3, only one of the plurality of first holes 114P1 and the plurality of second holes 114P2 may be provided at the second perforated region 114P (single perforation), or additional holes other than the plurality of first holes 114P1 and the plurality of second holes 114P2 may be further provided at the second perforated region 114P.

For example, the first and second plurality of holes 114P1 and 114P2 may each include four to ten holes (holes) that may be formed at intervals along the outer circumferential surface of the tipping wrapper 130, but the present invention is not limited thereto. The diameter of each hole may be about 0.02mm to 0.08mm (e.g., 0.05 mm), but the present invention is not limited thereto.

The holes may be formed by an in-line (on-line) perforation process, i.e. by making a cigarette using a non-porous tipping wrapper and then perforating the filter section. In-line perforation may be performed using a laser, but the present invention is not limited thereto. As described above, when perforated on-line, as shown in fig. 3, the holes may be formed not only in the tipping wrapper 130 but also in a portion of the region outside the combined wrapper 116, the second wrapper 114a, and thus the second filter 114, so that the external air can flow from the outside to the inside of the second filter 114 through the second perforated region 114P. The outside air introduced through the second perforations 114P can mix with the mainstream smoke and be delivered to the smoker.

In some embodiments, the first and second plurality of holes 114P1, 114P2 may have a separation distance 114Pw of about 0.5mm to 1.5mm. In other words, the plurality of first holes 114P1 may be spaced about 0.5mm to 1.5mm in the upstream direction from the plurality of second holes 114P 2.

In some embodiments, the first plurality of apertures 114P1 may be spaced about 22mm to 25mm from the upstream end of the tipping wrapper 130 (114p _ted), and the second plurality of apertures 114P2 may be spaced about 9mm to 12mm from the downstream end of the second filter 114 (114p _med).

As shown in fig. 3, the first and second pluralities of apertures 114P1 and 114P2 may be located in areas that do not overlap the second capsule 114c, i.e., upstream of the second capsule 114c.

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

In fig. 4, the same reference numerals as those in fig. 1 to 3 denote the same members, and a repetitive description will be omitted herein for convenience of description.

Referring to fig. 4, the smoking article 200 may include a smoking material portion 120, a smoking material wrapper 120a, a filter for smoking articles 110, and a tipping wrapper 230, and the filter for smoking articles 110 may include a first filter 112, a second filter 114, a first wrapper 112a, a second wrapper 114a, a first capsule 112c, a second capsule 114c, and a combined wrapper 116.

The first perforated region 212P may be formed in a tipping wrapper 230 of the smoking article 200. As shown in fig. 4, the first perforated region 212P may have double perforations, i.e., may have a plurality of first holes 212P1 formed along the outer circumferential surface of the tipping wrapper 230 and a plurality of second holes 212P2 formed along the outer circumferential surface of the tipping wrapper 130 downstream of the first holes 114P1, but the present invention is not limited thereto. For example, unlike what is shown in fig. 4, only one of the plurality of first holes 212P1 and the plurality of second holes 212P2 may be provided at the first perforated region 212P (single perforation), or additional holes other than the plurality of first holes 212P1 and the plurality of second holes 212P2 may be further provided at the first perforated region 212P.

The plurality of first holes 212P1 and the plurality of second holes 212P2 may be formed at intervals along the outer circumferential surface of the tipping wrapper 130, respectively, but the present invention is not limited thereto.

The apertures may be formed by an off-line perforation process, i.e. in the manner in which a pre-perforated tipping wrapper 230 is used to manufacture a cigarette. The off-line perforation may be performed using a laser, but the present invention is not limited thereto.

By forming a plurality of first apertures 212P1 and/or a plurality of second apertures 212P2, the porosity of the tipping wrapper 230 in the first perforated region 212P may be about 190CU to 210CU. In other words, the first plurality of apertures 212P1 and/or the second plurality of apertures 212P2 may be perforated such that the tipping wrapper 230 has a porosity of about 190CU to 210CU. This is because, when the porosity of the tipping wrapper 230 is less than about 190CU, the actual benefit in terms of the effect of increasing the delivery rate of the capsule content solution is less, and when the porosity of the tipping wrapper 230 is about 210CU or greater, mainstream smoke may leak through the first perforated region 212P.

As described above, when perforated off-line, the porosity of the tipping wrapper 230 in the first perforated region 212P becomes about 190CU to 210CU, so that, as shown in fig. 4, holes are formed only in the tipping wrapper 230, without extending to the combined wrapper 116 and the first wrapper 112a. Thus, the smoker ruptures the first capsule 112c so that the capsule content solution released outside the first capsule 112c can be better delivered to the smoker's hand without the apertures extending to the combined wrapper 116 and first wrapper 112a, thereby being able to prevent mainstream smoke from leaking outside the smoking article 200.

In some embodiments, the first and second plurality of holes 212P1 and 212P2 may have a separation distance 212Pw of about 1mm to 3mm. In other words, the plurality of first holes 212P1 may be spaced about 1mm to 3mm from the plurality of second holes 212P2 toward the upstream direction.

In some embodiments, the plurality of first holes 212P1 and the plurality of second holes 212P2 of the first perforated region 212P may be spaced apart a distance 212Pw that is about 1.5 to 3 times (e.g., 2 times) the spacing distance 114Pw of the plurality of first holes 114P1 and the plurality of second holes 114P2 of the second perforated region 114P. For example, the separation distance 212Pw may be about 2mm and the separation distance 114Pw may be about 1mm, but the invention is not limited thereto.

In some embodiments, the first plurality of apertures 212P1 may be about 10mm to 13mm (212p _, ted) from the upstream end of the tipping wrapper 230 and the second plurality of apertures 212P2 may be 20mm to 23mm (212p _, med) from the downstream end of the second filter 114.

In some embodiments, the plurality of second holes 212P2 of the first perforated region 212P may be spaced apart from the plurality of first holes 114P1 of the second perforated region 114P by a distance Per _ D of about 9mm to 10mm.

On the other hand, as shown in fig. 4, unlike the plurality of first holes 114P1 and the plurality of second holes 114P2 of the second perforated region 114P, the plurality of first holes 212P1 and the plurality of second holes 212P2 of the first perforated region 212P are located at a region overlapping the first capsule 112c, so that the smoker breaks the first capsule 112c so that the capsule content solution released to the outside of the first capsule 112c can be better delivered to the smoker's hand.

Hereinafter, the structure of the present invention and the effects thereof will be described in more detail by examples and comparative examples. However, these examples are only for illustrating the present invention more specifically, and the scope of the present invention is not limited by these examples.

First embodiment

For the purposes of example, the filter sections of the cigarettes prepared for the experiments were cut apart. A first filter comprising first capsules containing mango-flavour notes surrounded by oil-resistant untreated paper wrapper and made of cellulose acetate material and a second filter comprising second capsules containing apple-mint flavour notes surrounded by oil-resistant treated paper wrapper and made of cellulose acetate material are bonded to the smoking material portion using tipping paper.

At this time, the tipping paper used includes off-line perforations in the region overlapping the first capsule, and the smoking article is prepared by forming double perforations at positions spaced about 2mm apart in the upstream direction of the second capsule by the on-line perforations after joining with the tipping paper.

Second embodiment

Smoking articles were prepared in the same manner as in the first example, except that tipping paper was used in which no off-line perforations were formed in the region overlapping the first capsule.

First comparative example

A smoking article was produced in the same manner as in the second example, except that oil-resistant treated paper roll was used as the paper roll of the first filter.

First experimental example: sidestream smoke composition analysis before and after rupturing the first capsule

In order to measure the hand odor reduction effect when the filter of the embodiment of the present invention was applied, the sidestream smoke composition change of the first filter region occurring before and after rupturing the first capsule was analyzed.

Table 1 is a specification of smoking articles according to the first and second embodiments and the first comparative example for measuring a change in smoke (sidestream smoke) composition occurring in the first filter region where the first filter 112 is located before and after rupturing the first capsule 112c, and table 2 is a result of measuring a change in smoke composition occurring in the tipping wrapper region where the first filter 112 is located before and after rupturing the first capsule 112c using smoking articles according to the first and second embodiments and the first comparative example. The area of the tipping wrapper where the smoker will hold the first filter 112 while smoking, specifically, the area spaced about 15mm to 30mm upstream from the downstream end of the smoking article 100, more specifically, the area spaced about 18mm to 27mm upstream from the downstream end of the smoking article 100, so the smoke composition delivered to the smoker's hand in the holding area can be confirmed by the results of table 2.

TABLE 1

The first example, the second example and the first comparative example were all smoking articles having a length of about 100mm in the upstream and downstream directions, a circumference of about 17mm, and a tar content of about 2.0mg, which were tested under the same conditions in the specifications not shown in table 1, and which were smoked in an uncrossified state. As smoking conditions, the suction volume was set to 55ml, the suction time was set to 2 seconds, the suction cycle was set to 20 seconds, and the number of puffs was set to 12. To determine smoke composition, gas Chromatography (GC) analysis was performed on smoke trapped after tipping the tipping wrappers 130, 230 where the first filter 112 was wrapped with a Cambridge Filter Pad (CFP). The Nicotine (nicontine), 3-ethylpyridine (3-Ethyl Pyridine), 3-vinylpyridine (3-Ethyl Pyridine), pyridine (Pyridine) and Menthol (Menthol) compositions were measured by GC analysis, but the values for 3-ethylpyridine and 3-vinylpyridine are limits of quantitation (LOQ) and are therefore excluded from table 2.

TABLE 2

As shown in table 2, according to the results of measuring the smoke composition of the tipping wrappers 130, 230 on which the first filters 112 were located using the smoking articles according to the first embodiment, the second embodiment and the first comparative example, the menthol content of the first embodiment, the second embodiment and the first comparative example all increased after rupturing the first capsules 112c, nicotine in the sidestream smoke of the smoking articles according to the first embodiment, the second embodiment and the first comparative example decreased, and pyridine in the sidestream smoke of the smoking articles according to the second embodiment and the first comparative example decreased. Based on the results in table 2, but in consideration of the importance of the specific gravity of nicotine that is a cause of smoke smell and the amount of menthol delivered that plays a role in masking the smell, it is predicted that the effect of reducing hand odor due to smoking is the best in the first embodiment in which ordinary roll paper (i.e., roll paper that has not been subjected to oil resistance treatment) is used as the first wrapper 112a and the tipping wrapper 230 in the region where the first wrapper 112a is located is double-perforated by off-line perforation in such a manner that the porosity is approximately 200 CU. Also, it can be confirmed that in the case of the second embodiment using ordinary roll paper that has not been subjected to oil-resistant treatment as the first wrapper 112a, the amount of menthol conveyed is increased as compared with the first comparative example using oil-resistant treated roll paper as the first wrapper 112a, and therefore it can be expected that the hand odor reducing effect due to smoking is excellent.

Second experimental example: sensory evaluation based on hand odor reduction Effect Using first Capsule

In order to determine the hand odor reduction effect before and after rupturing the capsule of the smoking article of the first embodiment, sensory evaluation was performed on the degree to which the hand odor after smoking and the aroma other than smoke were felt.

Using the smoking article of the first example, 10 panelists were evaluated for sensory characteristics, and scored on a 9 point score basis.

Fig. 5 is the result of sensory characteristic evaluation according to whether the first capsule is ruptured or not of the smoking article according to the first embodiment of the present invention.

As shown in fig. 5, the smoking articles of the first embodiment in which the first capsule was ruptured and the smoking articles of the first embodiment in which the first capsule was not ruptured were analyzed for sensory characteristics expressed after smoking, and as a result, the smoking articles of the first embodiment in which the first capsule was ruptured had the degree of the smoke smell of the finger after smoking reduced by about 59% as compared with the case where the first capsule was not ruptured, and the smoking articles of the first embodiment in which the first capsule was ruptured had the degree of the fragrance of the finger after smoking other than the smoke smell increased by about 208% as compared with the case where the first capsule was not ruptured.

This means that the first filter includes the first capsule for reducing hand malodor, and the hand malodor reduction effect after smoking is better in the case of smoking after rupturing the first capsule than in the case of smoking after not rupturing the first capsule (i.e., the case of not including the first capsule).

Third experimental example: sensory evaluation of hand odor reduction Effect by perforation of first Filter

In order to confirm the hand odor reduction effect of the smoking article according to whether the first filter is perforated or not, sensory evaluation was performed on the degree to which the smoking articles according to the first and second embodiments were perceived as smoke smell of hands after smoking and other odors except smoke smell.

Using the smoking articles of the first and second examples, 10 panelists were evaluated for sensory characteristics, and scored on a 9 point scale.

Figure 6 shows the results of the sensory evaluation based on whether double perforation was applied to the tipping wrapper on which the first filter was located.

As a result of analyzing the sensory characteristics expressed after smoking of the smoking article of the first embodiment to which the double perforated structure is applied and the smoking article of the second embodiment to which the double perforated structure is not applied, as shown in fig. 6, there is no significant difference in the degree of smoke smell of the fingers after smoking. In contrast, the smoking article of the first embodiment to which the double perforation structure is applied has an increased fragrance level of fingers after smoking, except for the smoke smell, by about 27% as compared with the smoking article of the second embodiment to which the double perforation structure is not applied.

It is known that although it is difficult to consider that the smoke itself is removed or reduced by employing the perforated structure 212P described with reference to fig. 4, the flavor material contained in the first capsule is better transferred to the fingers of the smoker by the perforated structure, and thus the smoke covering effect of the fingers is improved by the aroma.

Fourth experimental example: analysis of composition of mainstream smoke before and after capsule rupture

In order to measure the halitosis-reducing effect when the filter of the embodiment of the present invention was applied, the change in the composition of the mainstream smoke before and after rupturing the capsule was analyzed.

Table 3 is the analysis results of the variation in mainstream smoke composition before and after rupture of the first capsule 112c and the second capsule 114c included in the smoking article according to the first embodiment of table 1. The results in table 3 confirm the smoke components in the mainstream smoke generated when the smoker smokes, and thus infer the degree of reduction in the smoke flavor in the mouth of the smoker.

TABLE 3

According to the smoke composition analysis results of the mainstream smoke, after rupturing the first and second capsules 112c and 114c, the ratio of nicotine was reduced from 7.2% to 5.4% after rupturing the capsules compared to the Total Particulate Matter (TPM) value excluding moisture compared to before rupturing the capsules, and the ratio of menthol was increased from 0% to 17.3% before rupturing the capsules compared to the TPM value excluding moisture. On the other hand, the TPM value after rupturing the first and second capsules 112c and 114c is increased by about 75% as compared to before rupturing the first and second capsules 112c and 114c, and the tar value is increased by about 77% as compared to before rupturing the first and second capsules 112c and 114c, which corresponds to an increased fraction of menthol and other aromates contained in the content solution of the first and second capsules 112c and 114c. That is, after the first capsule 112c and the second capsule 114c are ruptured, the smoke taste in the mouth of the smoker decreases and the aroma other than the smoke taste increases as the nicotine ratio to TPM decreases and the menthol ratio increases, and thus it is known that the smoke taste masking effect is exhibited.

Hereinafter, the structure of the present invention and the effects according thereto are described in more detail by examples and comparative examples according to the combination of the perfume of the first capsule and the perfume of the second capsule and whether or not there is rupture thereof. However, this example is intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.

Third embodiment

In this example, a cigarette for test was produced, and the filter portion was cut and separated. A tipping paper is used to bond a first filter comprising first capsules containing mango-flavour notes surrounded by oil-resistant paper wrapper and made of cellulose acetate material and a second filter comprising second capsules containing apple-mint flavour notes surrounded by oil-resistant paper wrapper and made of cellulose acetate material to the cut smoking material portion.

Here, the first capsule contained mango-flavor and the second capsule contained apple-mint-flavor, and the experiment was performed in a state where both the first and second capsules were ruptured.

Fourth embodiment

The first capsule contained mango flavor and the second capsule contained orange flavor, and the experiment was performed in a state where both the first and second capsules were broken. The same smoking article as the third embodiment was used with the remaining conditions.

Fifth embodiment

The first capsule contained mango-flavored essence and the second capsule contained strawberry-flavored essence, and the experiment was conducted in a state where both the first capsule and the second capsule were broken. The same smoking articles as in the third example, 4 were used.

Sixth embodiment

The first capsule contained mango-flavor and the second capsule contained wine-flavor, and the experiment was performed in a state where both the first and second capsules were broken. The same smoking articles as in the third embodiment to 5 were used.

Seventh embodiment

The first capsule and the second capsule respectively contain mango-flavor perfume, and the experiment was performed in a state where both the first capsule and the second capsule are ruptured. Smoking articles were used which were otherwise identical to those of the third to sixth embodiments.

Third comparative example

The experiment was performed in a state where the same smoking article as the third embodiment was used and neither the first capsule nor the second capsule was broken. Since each of the first capsule and the second capsule has a structure in which the content solution containing the flavor is surrounded by a film, the test relating to the flavorant in a state in which neither the first capsule nor the second capsule is broken can mean the test relating to the flavorant of the smoking article not including the first capsule and the second capsule.

Fourth comparative example

The experiment was performed in a state where only the first capsule was ruptured and the second capsule was not ruptured using the same smoking article as the third embodiment. For the same reason as in the third comparative example, the experiments relating to the fragrances in the state in which only the first capsule is ruptured and the second capsule is not ruptured may mean the experiments relating to the fragrances of the smoking article including only the first capsule and not the second capsule.

Fifth comparative example

The experiment was performed in a state where only the second capsule was ruptured and the first capsule was not ruptured using the same smoking article as the third embodiment. For the same reason as in the third comparative example, the experiments relating to the fragrances in the state in which only the second capsule is ruptured and the first capsule is not ruptured may mean the experiments relating to the fragrances of the smoking article including only the second capsule and not the first capsule.

On the other hand, in the fifth to seventh experimental examples described later, a cellulose acetate filter to which no flavorant substance is added was used as the second filter of the smoking article, but when a filter with a flavorant substance, for example, a TJNS filter, was used as the second filter, the effect of reducing halitosis and hand odor (which will be described later) was expected to be more excellent. For example, the TJNS filter may be a filter flavored with one flavor selected from mango, wine, mogitot, apple, orange, strawberry, green apple, apple mango, and sweet mango flavors.

In some embodiments, the second filter of the smoking article may be a TJNS filter flavored with green apple vanilla. Preferably, the second filter may be a TJNS filter that is flavored with about 2mg to 8mg of green apple vanilla flavor per filter (i.e., per cigarette). More preferably, the second filter may be a TJNS filter that is flavored with about 2.5mg to 3.5mg of green apple vanilla flavor per filter.

Fifth example of experiment: sidestream smoke composition analysis based on whether capsules are ruptured and perfume in the capsules

In order to measure the hand odor reduction effect when the filter according to the embodiment of the present invention was applied, the smoke (sidestream smoke) components in the first filter region generated for each perfume and before and after the first and second capsules were ruptured were analyzed.

Table 4 shows the type of flavor and the presence or absence of breakage in the capsules of the smoking articles according to the third to seventh embodiments and the third to fifth comparative examples. Table 5 is the measurement results of the menthol content in the sidestream smoke components in the tipping wrapper region where the first filter of the smoking articles according to the third to seventh examples and the third to fifth comparative examples is located, and tables 6 to 11 are the measurement results showing the names and the detected amounts of aroma-expressing components other than menthol in the sidestream smoke components of the smoking articles according to the third to seventh examples and the third to seventh examples.

The area of the tipping wrapper on which the first filter is normally held by the smoker when smoking, specifically the area spaced from the downstream end of the smoking article by about 15mm to 30mm in the upstream direction, more specifically the area spaced from the downstream end of the smoking article by about 18mm to 27mm in the upstream direction, so that the smoke composition delivered to the smoker's hand in the holding area can be determined from the results of tables 5 and 6 to 11.

TABLE 4

The third to seventh embodiments and the third to fifth comparative examples are each a smoking article having a length of about 100mm in the upstream and downstream directions, a circumference of about 17mm, and a tar content of about 2.0mg, and the first filter including the first capsule is surrounded by the oil-resistant untreated paper web, and the above-described second filter including the second capsule is surrounded by the oil-resistant treated oil-resistant paper web. The tipping paper used comprises off-line perforations in the region overlapping the first capsule, and the smoking article is prepared by forming double perforations at locations spaced about 2mm upstream of the second capsule after joining with the tipping paper by the on-line perforations. Except for this, experiments were carried out under the same conditions as those of the specifications not shown in table 4. As smoking conditions, the suction volume was set to 55ml, the suction time was set to 2 seconds, the suction cycle was set to 20 seconds, and the number of puffs was set to 12. To determine smoke composition, a cigarette was smoked with the tipping wrapper with the first filter surrounded by CFP, and smoking was repeated 5 times per sample in this manner, and then the CFP was placed in a glass bottle and extracted with methanol (MeOH) for GC analysis. Menthol (Menthol) and furanone (furanol) components, which are components related to hand odor reduction, were determined by GC analysis, except for Nicotine (nicotin), 3-ethylpyridine (3-Ethyl pyridine), and 3-vinylpyridine (3-Ethyl pyridine), which are main components inducing hand odor, but the furanone component could not be detected (no data), and thus the furanone component was excluded in table 5 below.

TABLE 5

As shown in table 5, menthol contents at levels of about 26ug/cig to 33ug/cig were detected in all of the third to seventh examples, i.e., about 13 to 17 times as much menthol content as the third comparative example (i.e., without rupturing the first and second capsules) was detected. Considering the importance of the delivered amount of menthol that plays a role in smoke masking, referring to the results of fig. 5, it is predicted that the third to seventh examples, in which both the first capsule and the second capsule are ruptured, have an increased hand odor masking effect due to smoking, as compared to the case where both the first capsule and the second capsule are not ruptured (third comparative example) and the case where only one of them is ruptured (fourth, fifth comparative examples). In particular, the above-described hand odor masking effect of the first embodiment, in which the flavor of the first capsule is predicted to be mango-flavored and the flavor of the second capsule is apple-minty, is the best. In tables 6 to 11 below, in which fragrance expression components other than menthol were analyzed in the sidestream smoke components, it was confirmed that components (D-limonene, 1-hexanol, 3-hexen-1-ol (Z) -, decanoic acid, methyl ester, geraniol, 1, 6-octadien-3-ol, 3, 7-dimethyl-and 2 (3H) -furanone, 5-hexyldihydro-) which could not be detected from the third comparative example in which the first capsule and the second capsule were not ruptured were transmitted to the outside of the tipping wrapper through rupture of the first capsule and the second capsule, and also transmitted to the hand of the smoker to exhibit a smoke taste masking effect.

In addition, although the results of the sensory evaluation may vary depending on various factors, it can be predicted that the values of the cooling sensation during smoking, refreshing aftertaste during smoking, overall satisfaction after smoking, and the degree of smoke smell of fingers after smoking are all good when the 2 (3H) -furanone, 5-hexyldihydro-component content in sidestream smoke is greater than the content of 1, 6-octadien-3-ol, 3, 7-dimethyl-or the 1-hexanol component content in sidestream smoke is greater than the content of decanoic acid, methyl ester component, considering only the results of the analysis of the aroma-expressing components in tables 6 to 11, with reference to the results of the sensory evaluation of the seventh experimental example.

TABLE 11

Sixth experimental example: halitosis trapping and analysis based on whether capsules were ruptured and perfume in capsules

In order to measure the bad breath reduction effect when the filter according to the example of the present invention was applied, bad breath before and after rupturing the first and second capsules according to the perfume was trapped and analyzed, and table 12 is the analysis results according to the third to seventh examples and according to the third to fifth comparative examples.

TABLE 12

Five oral malodor traps were performed for a total of five smoker subjects per example, with each interval set at 30 minutes. Halitosis was captured after 2 minutes of occlusion after each smoker had drawn one smoke, and the captured smoke was sampled in a 3L bag and analyzed by a Thermal Desorption (TD)/Gas Chromatography (GC) -Pulsed Flame Photometric Detector (PFPD). Hydrogen Sulfide (H2S), methyl Mercaptan (MM), dimethyl Sulfide (DMS) and dimethyl disulfide (DMDS) were analyzed as main components for inducing halitosis, but H was analyzed ₂ The detected concentrations of S, DMS and DMDS were concentrations at levels equal to or less than the threshold, i.e., significant results were hardly obtained, and thus excluded from table 12. Table 12 shows the measurement results of the Threshold Index (TI) of MM (referred to as methyl mercaptan, also called methyl mercaptan, hereinafter referred to as methyl mercaptan for convenience of description) of each example, and the above TI was calculated by dividing the median value of five measurements of each example by the Threshold value (0.07 ppb).

As shown in table 12, in the example in which both the first and second capsules were broken, the TI values of methyl mercaptan detected in the third, fourth, sixth, and seventh examples were lower than that of the third comparative example in which both the first and second capsules were not broken. Thus, the case where both the first and second capsules are broken has a tendency to substantially exhibit a methyl mercaptan reducing effect as compared to the case where neither or only one of the first and second capsules is broken.

On the other hand, it was confirmed that the effect of reducing these methyl mercaptans is not simply expressed by capsule rupture using a fruit-based flavor, but is expressed and maximized by interaction of an appropriate combination of the first capsule and the second capsule. This is because, even if both the first capsule and the second capsule are broken, in the case of the fourth and fifth examples, there is no significant value of the methyl mercaptan reducing effect, or the TI value of methyl mercaptan is increased on the contrary.

The third example (first capsule = mango, second capsule = apple mint), the sixth example (first capsule = mango, second capsule = wine), and the seventh example (first capsule and second capsule = mango) all showed an effect of reducing the amount of methyl mercaptan production by about 30% or more, as compared with the third comparative example (first capsule and second capsule are not broken), and the effect of reducing the amount of methyl mercaptan production of the third example was the best, with slight differences. Methyl mercaptan is an organic sulfur compound that emits an odor of rotten chinese cabbage or the like, which is mainly found in peanuts, cheese, radishes, or the like, and in the smoking articles of the third embodiment (first capsule = mango, second capsule = apple mint), the sixth embodiment (first capsule = mango, second capsule = wine), and the seventh embodiment (first capsule and second capsule = mango), it is predicted that the effect of reducing halitosis due to smoking is good, and by making a slight difference, the effect of reducing halitosis of the third embodiment is the best.

Seventh Experimental example: according to the third to seventh embodiments and the third to fifth comparative examples, the smoking and the smoking are performed Sensory evaluation of

Sensory evaluation was performed on the intensity of aroma during smoking, the cooling feeling, the satisfaction of aroma and refreshing aftertaste, the overall satisfaction after smoking, the degree of smoke staining on fingers, and the degree of aroma staining on fingers other than smoke of the smoking article of each example.

Using the smoking articles of the third to seventh examples and the third to fifth comparative examples, sensory characteristics were evaluated on 60 panelists, and the scores were scored based on a 7 point score.

Table 13 shows the sensory characteristics evaluation results of the smoking articles of the third to seventh examples and the third to fifth comparative examples of the present invention, and fig. 7 to 13 show the sensory characteristics evaluation results of the smoking articles of the third to seventh examples and the third to fifth comparative examples of the present invention.

Watch 13

As shown in table 13 and fig. 7, regardless of the type of the flavor, it was found that the smoking articles of the third to seventh embodiments in which both the first and second capsules were broken had increased the flavor intensity in smoking compared to the third to fifth comparative examples in which neither the first and second capsules were broken or only one of them was broken. In the case of the third to seventh embodiments in which both the first and second capsules are broken, the increase is about 50% or more as compared to the comparative example in which both the first and second capsules are not broken, about 40% or more as compared to the fourth comparative example in which the first capsule is broken only, and has a value equal to or more than the fifth comparative example in which the second capsule is broken only. It was confirmed that the influence of the rupture of the first capsule (fourth comparative example) is small and the influence of the second capsule is larger than that of the first capsule with respect to the flavor intensity in smoking. When comparing the results of the flavors of the third to seventh examples, it was found that the flavor intensity in smoking was the best in the case where the second capsule was wine-flavored, and the flavor intensity in smoking was the suboptimal in the case where the second capsule was apple-mint or mango-flavored.

As shown in table 13 and fig. 8, it was confirmed that the cooling sensation during smoking tended to be substantially similar to the flavor intensity during smoking. That is, regardless of the type of the flavor, it can be found that the smoking articles of the third to seventh embodiments in which both the first and second capsules are ruptured have an overall increased cooling sensation in smoking compared to the third to fifth comparative examples in which neither the first and second capsules are ruptured or only one of them is ruptured. Similarly, it was confirmed that the influence of the first capsule rupture (fourth comparative example) is small and the influence of the second capsule is larger than the influence of the first capsule with respect to the refreshing feeling during smoking.

When comparing the results obtained by the flavors of the third to seventh examples, it was found that the second capsule is best in the wine flavor or apple mint flavor in terms of refreshing feeling in smoking.

As shown in table 13 and fig. 9, there was no bias in dependence on any of the first capsule and the second capsule in terms of flavor satisfaction in smoking.

The third to seventh examples, in which both the first and second capsules were confirmed to be broken, showed higher scores than the third to fifth comparative examples, in which both the first and second capsules were not broken or only one of them was broken.

With respect to flavor satisfaction in smoking, the numerical difference of each flavor is even slightly different.

As shown in table 13 and fig. 10, regardless of the type of the flavor, it can be found that the refreshing of aftertaste in smoking of the smoking articles of the third to seventh embodiments in which both the first and second capsules are broken is increased as compared with the third comparative examples to 4 in which neither the first and second capsules are broken or only one of them is broken. As for refreshing of aftertaste in smoking, it can be confirmed that the effect of the second capsule is significantly larger than that of the first capsule.

When comparing the results obtained by the flavors of the third to seventh examples, it can be found that the refreshing of aftertaste in smoking is the best in the case where the second capsule is apple mint flavor, and the refreshing of aftertaste in smoking is the suboptimal in the case where the second capsule is wine flavor.

On the other hand, as for refreshing aftertaste in smoking, it was confirmed that the case of the fourth comparative example in which the first capsule is merely broken had a slightly lower value rather than the case of the third comparative example in which neither the first capsule nor the second capsule was broken, and even if both the first capsule and the second capsule were broken, the case of the fourth comparative example in which the second capsule was merely broken had a lower value rather than the case of the second capsule depending on the type of the flavor (fourth, fifth, seventh examples). Thus, the influence according to the interaction of the flavor combination of the first and second capsules on the refreshing of aftertaste in smoking is predicted to be greater than the influence on whether the first and second capsules are ruptured or not for the refreshing of aftertaste in smoking.

It was confirmed that the combination of flavors in the third embodiment in which the first and second capsules are mango and apple mint flavors, respectively, and the sixth embodiment in which the first and second capsules are mango and wine flavors, respectively, had an increasing effect in refreshing aftertaste.

As shown in table 13 and fig. 11, it was confirmed that the overall satisfaction after smoking tended to be substantially similar to the refreshing aftertaste during smoking. Regardless of the type of flavor, it can be found that the refreshing of aftertaste in smoking of the smoking articles of the third to seventh embodiments in which both the first and second capsules are ruptured is increased as compared to the third to fifth comparative examples in which neither the first and second capsules are ruptured or only one of them is ruptured.

When comparing the results of the flavors of the third to seventh embodiments, it can be found that the overall satisfaction after smoking is the best in the case where the second capsule is apple mint flavor, and the overall satisfaction after smoking in the case where the second capsule is wine flavor is suboptimal, similarly to the refreshing of aftertaste in smoking.

As shown in Table 13 and FIG. 12, regardless of the type of flavor, it was found that the smoking articles of the third to seventh embodiments in which both the first and second capsules were ruptured had a significantly increased degree of finger smoke smell after smoking as compared with the third comparative example in which neither the first and second capsules were ruptured or only one of them was ruptured. As for the degree of finger smoke smell after smoking, it was confirmed that the influence of the first capsule was significantly larger than that of the second capsule. Thus, it was confirmed that the masking effect of finger smoke was not substantially exhibited by merely rupturing the second capsule without rupturing the first capsule.

When comparing the results of the flavors of the third to seventh examples, the case where the second capsule is apple mint, strawberry, wine or mango flavored is relatively good in comparison with the case where the second capsule is orange flavored in the degree of the smoking taste of the finger after smoking.

As shown in table 13 and fig. 13, regardless of the type of the flavor, it can be found that the smoking articles of the third to seventh embodiments in which both the first and second capsules are broken increase the degree of aroma of the finger after smoking, except for the smoke smell, as compared with the third and fifth comparative examples in which neither the first and second capsules are broken or only one of them is broken. On the other hand, the third to seventh examples in which both the first and second capsules were broken and the fourth and fifth comparative examples in which only one of the first and second capsules was broken were not significantly different.

Considering that the fifth comparative example, shown in fig. 12, in which only the second capsule was ruptured had virtually no finger smoke reduction effect, it can be predicted that only causing the fragrance to be emitted on the finger may not exhibit a smoke masking effect.

When comparing the results of the flavors of the third to seventh examples, the degree of fragrance other than smoke after smoking is the best when the second capsule is wine-flavored. Also considering the results of fig. 12, it is seen that in the case where the second capsule is apple mint flavor, the degree of aroma of the fingers other than the smoke flavor is slightly smaller after smoking than in the case of other flavors, but the smoke flavor reducing effect of the fingers is the best after smoking.
