For example, in the smoking article 100 shown in fig. 1, the smoking material portion 120 is located at a position upstream or in the upstream direction of the filter 110 for the smoking article.
In the present specification, the case where the smoking article 100 is a combustion type cigarette is described as an example, but the present invention is not limited to this, and the smoking article 100 may be a heated cigarette or the like used together with an aerosol generating device (not shown in the drawings) such as an electronic cigarette or the like.
Fig. 1 is a diagram illustrating a schematic structure of a smoking article according to some embodiments of the invention.
Referring to fig. 1, a smoking article 100 may include a filter 110 for the smoking article, a smoking material portion 120, a smoking material wrapper 120a, and a tipping wrapper 130.
A filter 110 for a smoking article 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 a user.
The filter 110 for a smoking article may include a filter portion 112 and a filter wrapper 112a. The filter 110 for a smoking article may be a region arranged downstream of the smoking material portion 120 and through which aerosol material generated in the smoking material portion 120 passes before being drawn by a user.
The filter portion 112 may be formed of various materials, for example, the filter portion 112 may be a cellulose acetate filter.
In some embodiments, the filter portion 112 may be a tubular structure including a cavity therein. In this case, the diameter of the cavity included in the filter part 112 may employ an appropriate diameter in the range of 2mm to 4.5mm, but the present invention is not limited thereto. In addition, the filter portion 112 may be formed by inserting a structure such as a film or a tube having the same or different materials into the inside (e.g., a cavity).
The hardness of the filter portion 112 may be adjusted by adjusting the content of the plasticizer at the time of manufacturing the filter portion 112.
Triacetin (triacetin) may be used as the plasticizer, and the content of triacetin may be 5 to 15 weight% with respect to the total weight of the first filter 212 and the second filter 214, but the type and content of the plasticizer are not limited thereto, and may be appropriately adjusted as needed.
Although not shown in the drawings, a capsule may be contained inside the filter portion 112. The capsule may have a structure in which a content solution containing a perfume is surrounded by a film, and for example, the capsule may have a spherical shape or a cylindrical shape.
The material of the membrane forming the capsule 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 be further used as a material for the film forming the capsule. 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 a film of the capsule. Glycerol and/or sorbitol may be used as plasticizer here. And, the colorant may be further used as a material for forming a film of the capsule.
The content solution in the above capsule may include a perfume such as menthol and essential oils of plants. In some embodiments, as a solvent for the perfume of the content solution contained in the above-mentioned capsule, for example, medium chain fatty acid triglycerides (medium chain fatty acid triglyceride; MCTG) may be used. In addition, the content solution may contain other additives such as pigments, emulsifiers, thickeners, and the like.
The filter portion 112 may be wrapped with a filter wrapper 112 a. The filter wrapper 112a may be a porous web or a nonporous web. Also, the filter wrapping paper 112a may be made of roll paper that has not undergone oil resistance treatment, or conversely, may be made of roll paper having oil resistance.
The smoking material portion 120 may contain an aerosol-generating substance. For example, the smoking material portion 120 may comprise tobacco cut filler.
In some embodiments, the aerosol-generating substance may comprise at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.
The smoking material portion 120 may have a rod shape with an elongate extension, 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 flavoring, wetting agents, and/or acetate compounds. For example, the flavoring agent may include licorice, sucrose, fructose syrup, etc. (isosweet), cocoa, lavender, cinnamon, cardamon, celery, fenugreek, cascartia, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, coriander, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, red sage, spearmint, ginger, coriander, coffee, or the like. And, the wetting agent may further include glycerin or propylene glycol, etc.
In some embodiments, the smoking material portion 120 may include reconstituted tobacco material formed into a block like rod or the like by mixing it with solvents and various additives after grinding the tobacco raw material to make a slurry shape, and then drying to form a sheet. For example, the smoking material portion 120 comprises a plurality of filaments of tobacco material, 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 so limited.
By making the smoking material part 120 include a plurality of strand materials that process the wide-width tobacco sheet shape, the density of the tobacco material filled in the smoking material part 120 can be increased, so that the amount of aerosol generation can be increased, and the smoking characteristics of the smoking material part 120 can be improved.
The smoking material portion 120 may be wrapped with a smoking material wrapper 120 a. On the other hand, the amount of sidestream smoke generated may be determined by the overall structure of the smoking article 100, the tobacco leaf fit that may be included in the smoking material portion 120, and the like, and is particularly considerably affected by the characteristics of the smoking material wrapper 120a that wraps the smoking material portion 120. Accordingly, attempts have been made to reduce sidestream smoke by constructing the existing smoking material wrapper 120a as a dual wrapper or by varying the characteristics of the smoking material wrapper 120a, such as the fiber composition, porosity, filler, particle distribution, add-on, etc., of the smoking material wrapper 120 a. However, if the basis weight of the conventional cigarette paper is simply increased in order to reduce the sidestream smoke, the amount of fibers used increases, which results in an increase in fiber odor and odor during smoking, and thus the taste perceived by the smoker during smoking decreases, which has a limitation in terms of product applicability.
In contrast, in order to reduce sidestream smoke and prevent a decrease in tobacco flavor, a flavor including a first flavor material selected from vanillin (vanilin), ethyl vanilin (ethyl vanilin), and ethyl vanillin glucoside (ethyl vanillin glucoside) may be added to the smoking material wrapper 120a of the invention.
In some embodiments, the flavoring added to the smoking material wrapper 120a may include at least one or more second flavoring materials of Raspberry ketone (Raspberry ketone), menthol (menthol), methoxyacetophenone (methoxy acetophenone; or 4-acetylaniole), gamma undecalactone (gamma-undecalactone), methyl anthranilate (methyl anthranilate), cinnamic acid (cinamic acid), myristic acid (mythic acid), fennel oil (anite oil), lemon oil (lemon oil), and orange oil (orange oil), in addition to the first flavoring materials described above. For example, the ratio of the raspberry ketone and the first flavor material (e.g., ethyl vanillin) included in the smoking material wrapper 120a can be about 1:2 to 1:8, and preferably can be about 1:3 to 1:5 (e.g., 1:4). For example, the ratio of the menthol described above and the first flavor material (e.g., ethyl vanillin) included in the smoking material wrapper 120a can be about 1:0.5 to 1:1, preferably about 1:0.6 to 1:0.7 (e.g., 1:0.66).
In some embodiments, the weight ratio of the first flavor material (e.g., ethyl vanillin) can be about 0.5% to 0.7% (e.g., about 0.6%), the weight ratio of the raspberry ketone can be about 0.1% to 0.2% (e.g., about 0.15%), and the weight ratio of menthol can be about 0.8% to 1% (e.g., about 0.9%), relative to the weight of a smoking article 100. For example, the first flavor material (e.g., ethyl vanillin) included in a smoking article 100 can be about 1mg to 3mg (e.g., about 2 mg), the raspberry ketone can be about 0.4mg to 0.6mg (e.g., about 0.5 mg), and the menthol can be about 2mg to 4mg (e.g., about 3 mg).
In some embodiments, the first flavor material (e.g., ethyl vanillin) may be present in an amount of 0.1% or more, preferably about 0.5% or more and 10% or less, and more preferably about 0.8% or more and 6% or less, relative to the basis weight of the smoking material wrapper 120 a.
In some embodiments, to reduce sidestream smoke and effectively prevent reduced flavoring, the smoking material wrapper 120a comprising the first flavoring material described above may have a porosity of about 40CU to 50CU (e.g., 43 CU), and may have a basis weight of about 40g/m 2 To 50g/m 2 Preferably about 46g/m 2 To 47g/m 2 (e.g., 46.4 g/m) 2 ) The tensile strength may be about 1.45Kgf to 1.55Kgf (e.g., 1.51 Kgf), the flame retardant content may be about 0.7% to 1% (e.g., 0.84%), and the filler content may be about 20% to 23% (e.g., 21.4%).
The smoking article 100 may have a rod shape with an elongate extension, and may vary in length, diameter and circumference. For example, 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). As another example, the smoking article 100 may be about 7mm to 9mm (e.g., about 7.8 mm) in diameter and about 22.5mm to 26.5mm (e.g., about 24.5 mm) in circumference. On the other hand, in view of the discoloration problem caused by the basis weight and composition of the smoking material wrapper 120a described above, it is preferable that the total length 100L of the smoking article 100 to which the smoking material wrapper 120a of the present invention is applied may be about 90mm to 110mm (preferably about 100 mm), the circumference (or the width 120aW of the smoking material wrapper 120 a) may be about 14mm to 20mm (preferably about 17 mm), the length 120L of the smoking material portion 120 may be about 65mm to 75mm (preferably about 70 mm), and the length 110L of the filter 110 for smoking articles may be about 25mm to 35mm (preferably about 30 mm).
The smoking material portion 120 surrounded by the smoking material wrapper 120a and the filter portion 112 surrounded by the filter wrapper 112a may be combined and packaged by the tipping wrapper 130. That is, the tipping wrapper 130 may surround at least a portion (e.g., a downstream partial region) of the smoking material wrapper 120a and the periphery of the filter wrapper 112 a. In other words, at least a portion of the smoking material portion 120 and the filter portion 112 may be further wrapped and physically joined by the tipping wrapper 130.
The tipping wrapper 130 may be made from a conventional roll paper. For example, the tipping wrapper 130 may be a porous or nonporous roll. The tipping wrapper 130 may be made from the same roll paper as the filter wrapper 112a, but the invention is not limited thereto. For example, tipping wrapper 130 may be a nonporous roll of paper and filter wrapper 112a may be a porous roll of paper.
The tipping wrapper 130 may be made of roll paper that has not been subjected to oil-resistant treatment, but the invention is not limited thereto, and may of course be made of oil-resistant roll paper that has been subjected to oil-resistant treatment. In addition, the tipping wrapper 130 may be coated with a sweetener such as sucralose, citric acid, or the like.
In some embodiments, the tipping wrapper 130 may have a predetermined material added thereto. 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, or electrical insulation. However, any material having the above characteristics may be coated or coated on the tipping wrapper 130, even if not silicon, without limitation.
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 a smoking article, even the filter 110 for a smoking article may be burned. Even in this case, since the tipping wrapper 130 includes a non-combustible material, the phenomenon of burning of the filter 110 for the smoking article can be prevented.
Fig. 2 is a diagram showing a schematic structure of a smoking article employing a smoking article according to some embodiments of the invention, and fig. 3 is a partial cross-sectional view in the central axis direction of the smoking article according to some embodiments of the invention.
In figures 2 and 3 a smoking article 200 is disclosed which not only improves sidestream smoke as described with reference to figure 1, but also reduces hand malodor and bad breath created by smoking.
In fig. 2 and 3, the same reference numerals as in fig. 1 denote the same members, and for convenience of explanation, duplicate explanation will be omitted herein.
Referring to fig. 2 and 3, the smoking article 200 may include a filter 210 for the smoking article, a smoking material portion 120, a smoking material wrapper 120a, and a tipping wrapper 230, and the filter 210 for the smoking article may include a first filter 212, a second filter 214, a first wrapper 212a, a second wrapper 214, a first capsule 212c, a second capsule 214c, and a bonding wrapper 216.
The filter 210 for the smoking article may be a region disposed downstream of the smoking material portion and through which aerosol material generated in the smoking material portion passes before being drawn by a user.
The first filter 212 and the second filter 214 may be formed of various materials, for example, the first filter 212 and the second filter 214 may be cellulose acetate filters. The first filter 212 and the second filter 214 may have the same specification and composition, but the present invention is not limited thereto. For example, the first filter 212 is a cellulose acetate filter that is not flavored with a flavoring material, and the second filter 214 is a filter that is flavored with a flavoring material.
In some embodiments, the respective lengths of the first filter 212 and the second filter 214 may be suitably employed in the range of 4mm to 30mm, and the respective diameters of the first filter 212 and the second filter 214 may be suitably employed in the range of 5mm to 8mm, but the present invention is not limited thereto. Preferably, each length of the first filter 212 and the second filter 214 may be about 15mm, and each diameter of the first filter 212 and the second filter 214 may be about 5.4mm.
In some embodiments, the first filter 212 and/or the second filter 214 may be tubular structures that include a cavity therein. In addition, the first filter 212 and/or the second filter 214 may be made by inserting structures such as membranes, tubes having the same or different materials inside (e.g., cavities).
The hardness of the first filter 212 and/or the second filter 214 may be adjusted by adjusting the content of the plasticizer when the first filter 212 and/or the second filter 214 are manufactured.
The first filter 212 includes a first capsule 212c therein, and the second filter 214 includes a second capsule 214c therein. The first capsule 212c and/or the second capsule 214c may have a structure in which a content solution containing a perfume is surrounded by a film, for example, the first capsule 212c and/or the second capsule 214c may have a spherical shape or a cylindrical shape.
The material forming the membrane of the first capsule 212c and/or the second capsule 214c may be starch and/or a gelling agent. In addition, a gelling aid may further be used as a material for forming the film of first capsule 212c and/or second capsule 214c. In addition, a plasticizer may be further used as a material for forming the film of the first capsule 212c and/or the second capsule 214c. And, the colorant may further serve as a material for forming a film of the first capsule 212c and/or the second capsule 214c.
The content solution in the first capsule 212c and/or the second capsule 214c may include flavors such as menthol and essential oils of plants.
In some embodiments, the first capsule 212c and the second capsule 214c may each include a flavor selected from mango, wine, moguisorba, apple mint, orange, strawberry, green apple vanilla, apple mango, and sweet mango. Here, the first capsule 212c and the second capsule 214c may include different kinds of perfume, but the present invention is not limited thereto. For example, the first capsule 212c may include a mango-flavored flavor, and the second capsule 214c may include an apple mint-flavored flavor.
On the other hand, in order to maximize the speed at which the perfume contained in the capsule is transferred to the fingers through the wrapper 212a,216,230 after the capsule is ruptured, the content of the perfume contained in the first capsule 212c may be about 20 to 50 weight percent with respect to the total weight of the capsule, and the perfume may be a highly volatile fruit-based flavor that can be easily released to the outside of the wrapper.
In some embodiments, as a solvent for the perfume of the content solution contained in the first capsule 212c and/or the second capsule 214c, for example, medium chain fatty acid triglycerides may be used. In addition, the content solution may contain other additives such as pigments, emulsifiers, thickeners, and the like.
The first filter 212 and the second filter 214 may be surrounded by a wrapper 212a, 214a, 216. More specifically, the first filter 212 may be surrounded by a first wrapper 212a, the second filter 214 may be surrounded by a second wrapper 214a, and the first filter 212 and the second filter 214 may be jointly surrounded by a joint wrapper 216. In other words, the first filter 212 surrounded by the first wrapper 212a and the second filter 214 surrounded by the second wrapper 214 are further wrapped and physically bonded by the bonding wrapper 216.
The first wrapper 212a and the bonding wrapper 216 may be made of plain roll paper that has not been subjected to oil resistance treatment. For example, the first wrapper 212a and the bonding wrapper 216 may be porous or nonporous paper. For example, the first wrapper 212a and the bonding wrapper 216 may be a nonporous roll of paper having a porosity of about 10CU to 20CU, or a porous roll of paper having a porosity equal to or greater than about 6500CU (e.g., 24000 CU).
The first wrapper 212a and the bonding wrapper 216 may be applied to the same roll paper, but the present invention is not limited thereto, and may be applied to roll papers having different characteristics. For example, one of the first wrapper 212a and the bonding wrapper 216 may be a porous roll paper and the other wrapper may be a non-porous roll paper.
The first wrapper 212a and the bonding wrapper 216 may be made of roll paper that is not oil resistant treated. That is, the first wrapper 212a and the bonding wrapper 216 may be made of roll paper that is not subjected to oil resistance treatment, so that the capsule content solution that is ruptured by the smoker to be released outside the first capsule 212c is transferred to the hands of the smoker through the first wrapper 212 a.
The second wrapping paper 214 may be made of roll paper having oil resistance. That is, the second wrapper 214a may be made of oil-resistant roll paper to prevent the capsule contents solution released to the outside of the second capsule 214c from being ruptured by the smoker from passing through the second wrapper 214. In some embodiments, the inner side of the second wrapper 214 may further comprise aluminum foil.
As shown in fig. 2, the filter 210 for a smoking article described above is arranged downstream of the smoking material part 120 to function as a filter through which aerosol material generated in the smoking material part 120 passes before being drawn by a user.
The smoking material portion 120 surrounded by the smoking material wrapper 120a and the filters 212, 214 surrounded by the bonding wrapper 216 may be bonded and packaged by the tipping wrapper 230. That is, the tipping wrapper 230 may surround at least a portion (e.g., a downstream partial region) of the smoking material wrapper 120a and the periphery of the bond wrapper 216. In other words, at least a portion of the smoking material portion 120 and the filters 212, 214 may be further wrapped and physically joined by the tipping wrapper 230.
In some embodiments, the length 230L1 of the tipping wrapper 230 can be about 33mm to 37mm. In the case where the length of the filter 210 for a smoking article is 30mm, the length 230L2 of the tipping wrapper 230 overlapping the smoking material portion 120 may be about 3mm to 7mm.
The smoking article 200 may have a rod shape with an elongate extension, and may vary in length and diameter. For example, the smoking article 200 can be about 45mm to 100mm in length and about 5mm to 9mm in diameter.
However, in view of the discoloration problem caused by the basis weight and composition of the smoking material wrapper 120a described above, the overall length of the smoking material 200 is about 90mm to 110mm (preferably about 100 mm), the circumference (or width of the smoking material wrapper 120 a) is about 14mm to 20mm (preferably about 17 mm), the length of the smoking material portion 120 is about 65mm to 75mm (preferably about 70 mm), the length 212L of the first filter 212 is about 10mm to 20mm (preferably about 15 mm), and the length 214L of the second filter 214 is about 10mm to 20mm (preferably about 15 mm).
The first capsule 212c and the second capsule 214c may have spherical shapes, and the diameter 212c_d of the first capsule 212c and the diameter 214c_d of the second capsule 214c may be about 2.6mm to 3.0mm. In some embodiments, the diameter 212c_d of the first capsule 212c and the diameter 214c_d of the second capsule 214c may be the same, but the invention is not limited thereto.
The first capsule 212c may be disposed in a position to grasp the smoking article 200 when a typical smoker smokes. Preferably, the first capsule 212c may be located at the downstream end of the second filter 214, i.e., at a position spaced approximately 18mm to 27mm in the upstream direction from the downstream end of the smoking article 200. As a more specific example, the center point of the first capsule 212c may be located at a position spaced about 21mm to 24mm from the downstream end of the smoking article 200 toward the upstream direction, the upstream end of the first capsule 212c may be located at a position spaced about 22.5mm to 25.5mm from the downstream end of the smoking article 200 toward the upstream direction, and the downstream end of the first capsule 212c may be located at a position spaced about 19.5mm to 22.5mm from the downstream end of the smoking article 200 toward the upstream direction.
The first capsule 212c and the second capsule 214c may have a separation distance cap_d of about 10mm to 14 mm. In other words, the first capsule 212c may be located at a position spaced about 10mm to 14mm apart from the second capsule 214c in the upstream direction.
The second perforated area 214P may be formed at the wrapping paper 214a, 216, 230 at a portion covering the second filter 214. As shown in fig. 3, the second perforated region 214P may have double perforations, that is, may have a plurality of first holes 214P1 formed along the outer circumferential surface of the tipping wrapper 230 and a plurality of second holes 214P2 formed along the outer circumferential surface of the tipping wrapper 230 downstream of the first holes 214P1, but the present invention is not limited thereto. For example, unlike the one shown in fig. 3, only one of the plurality of first holes 214P1 and the plurality of second holes 214P2 may be provided at the second perforated area 214P (single perforation), or additional holes other than the plurality of first holes 214P1 and the plurality of second holes 214P2 may be further provided at the second perforated area 214P.
For example, the plurality of first holes 214P1 and the plurality of second holes 214P2 may include four to ten holes (holes), respectively, which may be formed at intervals along the outer circumferential surface of the tipping wrapper 230, 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 above-mentioned holes may be formed by an in-line (on-line) perforation method, that is, by manufacturing cigarettes using a non-porous tipping wrapper, and then perforating the filter portion. The above-described in-line perforation may be performed using a laser, but the present invention is not limited thereto. As described above, when the line is perforated to form the holes, as shown in fig. 3, the holes may be formed not only in the tipping wrapper 230 but also to the bonding wrapper 216, the second wrapper 214, and further to the outer partial region of the second filter 214, so that external air may flow from the outside to the inside of the second filter 214 through the second perforated region 214P. The external air introduced through the second perforations 214P may be mixed with the mainstream smoke and delivered to the smoker.
In some embodiments, the plurality of first holes 214P1 and the plurality of second holes 214P2 may have a separation distance 214Pw of about 0.5mm to 1.5mm. In other words, the plurality of first holes 214P1 may be spaced from the plurality of second holes 214P2 by about 0.5mm to 1.5mm in the upstream direction.
In some embodiments, the first plurality of apertures 214P1 may be about 22mm to 25mm (214 p—ted) from the upstream end of the tipping wrapper 230 and the second plurality of apertures 214P2 may be about 9mm to 12mm (214 p—med) from the downstream end of the second filter 214.
As shown in fig. 3, the plurality of first holes 214P1 and the plurality of second holes 214P2 may be located in a region that does not overlap the second capsule 214c, i.e., upstream of the second capsule 214 c.
Figure 4 is a partial cross-sectional view in the central axis direction of a smoking article according to some embodiments of the present invention.
In fig. 4, the same reference numerals as those of fig. 1 to 3 denote the same members, and for convenience of explanation, duplicate explanation will be omitted herein.
Referring to fig. 4, a smoking article 300 may include a smoking material portion 120, a smoking material wrapper 120a, a filter 210 for the smoking article, and a tipping wrapper 330, and the filter 210 for the smoking article may include 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 bonding wrapper 216.
The first perforated region 312P may be formed in the tipping wrapper 330 of the smoking article 300. As shown in fig. 4, the first perforated area 312P may have double perforations, that is, may have a plurality of first holes 312P1 formed along the outer circumferential surface of the tipping wrapper 330 and a plurality of second holes 312P2 formed along the outer circumferential surface of the tipping wrapper 330 downstream of the first holes 314P1, but the present invention is not limited thereto. For example, unlike the one shown in fig. 4, only one of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be provided in the first perforated area 312P (single perforation), or additional holes other than the plurality of first holes 312P1 and the plurality of second holes 312P2 may be further provided in the first perforated area 312P.
Each of the plurality of first holes 312P1 and the plurality of second holes 312P2 may be formed at intervals along the outer circumferential surface of the tipping wrapper 130, but the present invention is not limited thereto.
The above-described holes may be formed by an off-line (off-line) perforation method, i.e., in a manner that the cigarettes are manufactured using the pre-perforated tipping wrapper 330. The offline perforation described above may be performed using a laser, but the present invention is not limited thereto.
By forming the plurality of first holes 312P1 and/or the plurality of second holes 312P2, the porosity of the tipping wrapper 330 in the first perforated region 312P can be about 190CU to 210CU. In other words, the first plurality of apertures 312P1 and/or the second plurality of apertures 312P2 may be perforated to provide the tipping wrapper 330 with a porosity of about 190CU to 210CU in size. This is because when the porosity of the tipping wrapper 330 is less than about 190CU, there is little practical benefit in terms of the effect of increasing the transfer rate of the capsule content solution, and when the porosity of the tipping wrapper 330 is about 210CU or greater, mainstream smoke may leak through the first perforated region 312P.
As described above, when the holes are perforated offline to form the holes, the porosity of the tipping wrapper 330 in the first perforated region 312P becomes about 190CU to 210CU, and thus, as shown in fig. 4, the holes are formed only in the tipping wrapper 330 and do not extend to the bonding wrapper 216 and the first wrapper 212a. Thereby, the capsule content solution that the smoker breaks the first capsule 212c to release to the outside of the first capsule 212c can be better delivered to the hands of the smoker, and the above-mentioned holes do not extend to the joining wrapper 216 and the first wrapper 212a, so that the mainstream smoke can be prevented from leaking to the outside of the smoking article 300.
In some embodiments, the plurality of first holes 312P1 and the plurality of second holes 312P2 may have a separation distance 312Pw of about 1mm to 3mm. In other words, the plurality of first holes 312P1 may be spaced apart from the plurality of second holes 312P2 by about 1mm to 3mm in the upstream direction.
In some embodiments, the spacing distance 312Pw of the plurality of first holes 312P1 and the plurality of second holes 312P2 of the first perforated region 312P may be about 1.5 times to 3 times (e.g., 2 times) the spacing distance 214Pw of the plurality of first holes 214P1 and the plurality of second holes 214P2 of the second perforated region 214P. For example, the interval distance 312Pw may be about 2mm, and the interval distance 214Pw may be about 1mm, but the present invention is not limited thereto.
In some embodiments, the first plurality of apertures 312P1 may be about 10mm to 13mm (312p_ted) from the upstream end of the tipping wrapper 330, and the second plurality of apertures 312P2 may be 20mm to 23mm (312p_med) from the downstream end of the second filter 214.
In some embodiments, the spacing distance per_d of the plurality of second holes 312P2 of the first perforated region 312P from the plurality of first holes 214P1 of the second perforated region 214P may be about 9mm to 10mm.
On the other hand, as shown in fig. 4, unlike the plurality of first holes 214P1 and the plurality of second holes 214P2 of the second perforated area 214P, the plurality of first holes 312P1 and the plurality of second holes 312P2 of the first perforated area 312P are located in an area overlapping the first capsule 212c, so that the capsule content solution, which the smoker breaks the first capsule 212c to release outside the first capsule 212c, can be better delivered to the smoker's hand.
As described above, in the smoking article 100, 200, 300 according to the embodiment of the present invention, the flavours including the first flavourant material such as ethyl vanillin and the like (and the second flavourant material such as raspberry ketone and the like) are coated on the smoking material wrapper 120a, and furthermore, the first filter 212 may include the first capsule 212c containing the flavourant capable of reducing the hand odour (and bad breath) of the smoker, and the second filter 214 may include the second capsule 214c containing the flavourant capable of reducing the bad breath of the smoker, so that the smell (sidestream smoke smell, hand odour and bad breath) that may be generated due to smoking can be reduced and the reduction of the taste of the smoke can be prevented.
On the other hand, a flavor including the above-described first flavor material such as ethyl vanillin and the like (and second flavor material such as raspberry ketone and the like) may be added to the smoking material wrapper in various ways. For example, the above-described flavourant may be added to the smoking material wrapper 120a described with reference to figures 1 to 4 prior to manufacture of the smoking article, and then applied directly to the flavourant, and then applied to the cigarette. In addition, after the smoking article is manufactured, the above-described flavourant may be added to the smoking article housing that houses the manufactured smoking article and transferred to the smoking article. A smoking article housing according to another embodiment of the invention is described in detail below.
Fig. 5 is a diagram showing a schematic structure of a smoking article casing according to some embodiments of the present invention, and fig. 6 is a diagram in which an inner liner included in the above smoking article casing is unfolded on a plane.
Referring to fig. 5 and 6 each other, the smoking article housing 1000 may include a housing body 1100 housing the smoking article 100 and an inner liner 1200 disposed between the housed smoking article 100 and the housing body 1100 in a manner surrounding the smoking article 100.
The housing body 1100 may include a housing lower body 1110 and a housing upper body 1120, the upper portion of the housing lower body 1110 being opened and formed with a space inside for accommodating the smoking article 100, the housing upper body 1120 being connected to the upper rear end of the housing lower body 1110 in a folded manner so that the upper portion of the housing lower body 1110 is opened and closed.
The inner liner 1200 may be arranged in such a manner as to surround at least one side of the smoking article 100, preferably in such a manner as to surround the smoking article 100 from four directions, in order to more stably protect the smoking article within the housing body 1100 and to prevent the smoking article 100 from being easily exposed to the outside. For example, the liner 1200 may be folded along the liner fold line 1200f shown in fig. 6 to square around the smoking article 100.
The inner liner 1200 may include an inner liner riding line 1200p for easily separating and removing the inner liner 1200a of the front upper region from the inner liner 1200b of the front lower region so that a smoker can easily remove the smoking article 100.
The flavor composition may be applied to at least a partial region of the liner 1200 in order to transfer the flavor component to the smoking article 100 stored in the smoking article housing 1000.
In some embodiments, the above-described fragrance composition may be applied to only one side of the liner 1200, and not to the other side opposite the one side. More specifically, the above-described flavor composition may be applied to only one of the two sides of the liner 1200 that is in contact with the smoking article 100, and not to the other of the two sides of the liner 1200 that is in contact with the inner side of the housing body 1100. On the other hand, in order to transfer the above-described flavor composition only to the smoking article 100 and to prevent the above-described flavor composition from leaking toward the housing main body 1100 or toward the outer region of the housing main body 1100 to the minimum, the other side surface of the inner liner 1200 may be coated with aluminum foil or the like or subjected to oil-resistant treatment.
In some embodiments, the perfume applied to the inner liner 1200 may include a first perfume material selected from vanillin, ethyl vanillin, and ethyl vanillin glucoside, and as a material other than the first perfume material, may include at least one second perfume material selected from raspberry ketone, menthol, methoxyacetophenone, gamma-undecalactone, methyl anthranilate, cinnamic acid, myristic acid, anise oil, lemon oil, and orange oil. As an example, the above-described perfume composition may include about 20% by weight of ethyl vanillin, about 5% by weight of raspberry ketone, about 30% by weight of menthol, and about 45% by weight of ethanol, relative to the total weight of the perfume composition.
In some embodiments, the overall length 1200L of the liner 1200 included in one smoking article housing 1000 may be about 220mm to 230mm (e.g., 227 mm), the width 1200W may be about 65mm to 75mm (e.g., 70 mm), the total amount of flavorant applied to the liner 1200 may be about 200mg, wherein the amount of ethyl vanillin may be about 40mg, the amount of raspberry ketone may be about 10mg, the amount of menthol may be about 60mg, and the amount of ethanol may be about 90mg. Assuming that the flavor composition applied to the liner 1200 described above is transferred to 20 smoking articles 100 contained in the smoking article housing 1000, about 2mg of ethyl vanillin, about 0.5mg of raspberry ketone, and about 3mg of menthol may be included in 1 tobacco. The 1 tobacco may include about 0.6 wt.% ethyl vanillin, about 0.15 wt.% raspberry ketone, and about 0.9 wt.% menthol relative to the total amount of 1 tobacco.
On the other hand, the length and width of the liner 1200, the total amount of the perfume applied to the liner 1200, etc. are merely values as an example, and the present invention is not limited thereto. The total amount of fragrance (or amount of ethyl vanillin, etc.) applied to the liner 1200 may depend on the area of the liner 1200. For example, the overall length 1200L of the liner 1200 may be about 150mm to 160mm (e.g., 155 mm), the width 1200W may be about 110mm to 120mm (e.g., 114.5 mm), and the total amount of fragrance applied to the liner 1200 may be about 223.4mg.
In some embodiments, the fragrance applied to the liner 1200 may have a basis weight of about 1g/m 2 To 20g/m 2 Preferably, it may be about 10g/m 2 To 15g/m 2 . And the basis weight of the ethyl vanillin applied to the liner may be about 0.2g/m 2 To 4g/m 2 Preferably, it may be about 2g/m 2 To 3g/m 2 . And the raspberry ketone applied to the liner may have a basis weight of about 0.05g/m 2 To 1g/m 2 Preferably, it may be about 0.5g/m 2 To 0.75g/m 2 . The menthol applied to the liner may have a basis weight of about 0.3g/m 2 To 6g/m 2 Preferably, it may be about 3g/m 2 To 4.5g/m 2 。
As described above, when the flavorant is applied to the inner liner 1200 included in the smoking article housing 1000, the first flavorant material (and the second flavorant material) is transferred to the smoking article 100, thereby masking sidestream smoke that occurs when the smoking article 100 is smoked, to reduce tobacco odors. The flavor-coated liner 1200 may be used with the smoking article described with reference to fig. 1-4 as being suitable for flavor-coated cigarette paper, but the invention is not limited thereto and may also be used with smoking articles that are suitable for non-flavor-coated cigarette paper. For example, the flavorant is coated on the inner liner 1200 of the smoking article housing 1000, and the smoking article included in the smoking article housing 1000 can be a non-flavor-added smoking article.
Hereinafter, the structure of the present invention and the effects thereof will be described in more detail with reference to examples and comparative examples. However, these examples are only for more specifically explaining the present invention, and the scope of the present invention is not limited by these examples.
First embodiment
After removing the wrapper surrounding the tobacco material of the cigarettes tested for the examples, cigarettes were prepared that were suitable for use with the wrapper having the physical properties of the first example in table 1 below.
Second embodiment
After manufacturing cigarettes to which the cigarette paper having the physical properties of the following first comparative example was applied, the manufactured cigarettes were stored in a smoking article case using the liner coated with the flavor composition described with reference to fig. 5 to 6, and then stored for about two months. The smoking article housing containing the cigarettes was stored in an air conditioning room at a temperature of about 22 ℃ and a humidity of about 62.5%.
The liner has a length of about 227mm and a width of about 70mm, and the liner fragrance is uniformly applied only to one of the two sides of the liner which contacts the cigarette, and not to the other side which contacts the inner side of the housing body of the smoking article housing. And aluminum foil is coated on the other side contacted with the inner side surface of the shell main body.
The total amount of the lining fragrant liquid uniformly applied to the lining was about 200mg, the content of ethyl vanillin was about 20 wt% (about 40 mg), the content of raspberry ketone was about 5 wt% (about 10 mg), the content of menthol was about 30 wt% (about 60 mg), and the content of ethanol was about 45 wt% (about 90 mg), relative to the total weight of the lining fragrant liquid. The fragrance applied to the liner had a basis weight of about 12.6g/m 2 The basis weight of ethyl vanillin is about 2.5g/m 2 。
First comparative example
As a cigarette paper surrounding a tobacco material, cigarettes to which a cigarette paper having the physical properties of the first comparative example of table 1 below was applied were prepared.
TABLE 1
The cigarettes according to the first to second examples and the first comparative example were smoking articles having a length of about 100mm in the upstream and downstream directions, a circumference of about 17mm, and tar of about 1.0mg, and the characteristics of the respective smoking material wrappers applied to the first to second examples and the first comparative example are shown in table 1, as described above. In table 1, the main difference between the first embodiment and the second embodiment and the first comparative example is whether ethyl vanillin is added in the preparation of the smoking material wrapper, and the amount of ethyl vanillin added to the cigarette paper according to the first embodiment is 1% relative to the basis weight of the smoking material wrapper, i.e., about 0.46g/m 2 。
First experimental example: analysis of the composition of sidestream and mainstream smoke produced during smoking
In order to analyze the composition of the sidestream smoke and the mainstream smoke of the cigarettes according to the first to second embodiments and the first comparative example of the present invention, the sidestream smoke and the mainstream smoke generated when each cigarette is smoked were trapped. Each sample was repeatedly subjected to 3 smoke traps, each trapping 70mL of sidestream smoke and 20mL of mainstream smoke. The results of the component analysis based on the average value of the trapping results of 3 times are shown in table 2 and fig. 7. Cigarettes were tested using an automatic smoking device according to the Health Canada (HC) smoking conditions in a smoking chamber at a temperature of about 20 ℃ and a humidity of about 62.5%.
TABLE 2
As shown in table 2 and fig. 7, about 3.2 times or more ethyl vanillin and 2.5 times or more vanillin were detected in the sidestream smoke of the cigarette according to the first example compared to the sidestream smoke of the cigarette according to the first comparative example, and about 5 times or more ethyl vanillin and 2.5 times or more vanillin were detected in the mainstream smoke. No raspberry ketone was detected in both samples, and it was presumed that ethyl vanillin detected in the sidestream smoke and mainstream smoke of the first comparative example to which no ethyl vanillin was added when preparing a smoking material wrapper occurred from a smoking material portion of a cigarette other than the smoking material wrapper, or the like. From the above results, it was confirmed that ethyl vanillin added when preparing a smoking material wrapper surrounding a smoking material portion of a cigarette was transmitted to the outside of the cigarette through mainstream smoke and sidestream smoke when the cigarette was smoked. Thus, it is predicted that the sidestream smoke and mainstream smoke generated when cigarettes are smoked according to the first embodiment are improved, and that the bad tobacco smell generated upon smoking by the increased ethyl vanillin is reduced. On the other hand, ethyl vanillin was detected in the sidestream smoke of the cigarette according to the second example about 82 times or more as compared to the sidestream smoke of the cigarette according to the first comparative example, and ethyl vanillin was detected in the mainstream smoke about 150 times. In the first example and the first comparative example, no raspberry ketone was detected in the samples, and thus it was difficult to compare the values of raspberry ketone, but referring to the values of ethyl vanillin or vanillin detected in the first example and the first comparative example, it was confirmed that raspberry ketone having a significant value or more was detected in the second example. It is predicted that when raspberry ketone ingredients are included in both sidestream smoke and mainstream smoke as shown in the second embodiment, an improvement in sidestream smoke and/or mainstream smoke or a masking effect of tobacco smoke smell is produced by the fragrance of raspberry ketone. From the above results, it was confirmed that the aroma liquid (i.e., ethyl vanillin, raspberry ketone, etc.) applied to the inner liner in the outer shell of the cigarette was transferred to the cigarette, and when the cigarette was smoked, the ethyl vanillin and raspberry ketone were transferred to the outside of the cigarette through the mainstream smoke and the sidestream smoke. Thus, the sidestream smoke and mainstream smoke generated when the cigarette according to the first embodiment is smoked are improved, and the bad smoke taste occurring upon smoking is reduced by the increased ethyl vanillin and the newly occurring raspberry ketone.
On the other hand, in the second embodiment by applying ethyl vanillin to the inner liner and transferring to the cigarette paper, unlike the result of the first embodiment in which ethyl vanillin is applied to the cigarette itself, the value of ethyl vanillin is merely increased, and the amount of vanillin is not significantly different from that of the first comparative example.
When comparing the results of the second example with the first example, more than about 25 times more ethyl vanillin was detected in the sidestream smoke of the cigarette according to the second example than in the sidestream smoke of the cigarette according to the first comparative example, and about 30 times more ethyl vanillin was detected in the mainstream smoke. It is thus predicted that the sidestream smoke and mainstream smoke of the second embodiment improve and the tobacco smell reduction effect is more improved than the first embodiment.
On the other hand, in the second embodiment, not only is the absolute value simply increased, but the amount of ethyl vanillin included in the smoke (sidestream smoke and mainstream smoke) is also advantageous compared to the first embodiment, as compared to the added amount of ethyl vanillin. Specifically, the ethyl vanillin applied to the liner of the second embodiment had a basis weight of about 2.5g/m 2 This is 0.46g/m of ethyl vanillin as a basis weight directly added to the cigarette paper of the first embodiment 2 Is about 5.5 times the number of the sample. Considering that the second embodiment provides about 25 times more ethyl vanillin detection in sidestream smoke than the first embodiment and ethyl fragrance in mainstream smokeThe detected amount of vanillin was about 30 times that of the first example, and it was confirmed that when the same amount (or the same basis weight or the like) of ethyl vanillin was applied, the aerosol generating effect of ethyl vanillin of the second example was significantly higher than that of the first example, which was presumably caused by the loss of the aroma fluid in the process of preparing cigarettes or the like after adding the aroma fluid to the cigarette paper. Alternatively, as shown in the second embodiment, when the flavor liquid is applied to the inner liner and then the cigarette is stored in the outer shell of the smoking article, it is presumed that, as shown in the first embodiment, the flavor liquid is more uniformly transferred to the constituent elements (for example, the smoking material portion, the filter, etc.) of the cigarette other than the cigarette paper than in the case of directly adding the flavor liquid to the cigarette paper and then storing the cigarette paper, and thus, the aerosolization of ethyl vanillin during smoking is facilitated.
Second experimental example: sensory evaluation of sidestream smoke and of taste upon smoking
Sensory evaluation was performed in order to confirm the odor reducing effect and the degree of odor reduction of the sidestream smoke of the cigarettes according to the first to second examples and the first comparative example of the present invention, and the results thereof are shown in fig. 8 and 9.
Fig. 8 is a sensory characteristic evaluation result of sidestream smoke of cigarettes according to the first to second examples and the first comparative example, and fig. 9 is a sensory characteristic evaluation result of taste of cigarettes according to the first to second examples and the first comparative example.
Sensory property evaluations of fig. 8 and 9 were performed on 60 panelists, and scoring was based on a 7-point full scale.
As shown in fig. 8, the smoking article of the first example, in which ethyl vanillin was added to the wrapper of the smoking material, had a side stream smoke sweetness increased by about 11%, a side stream smoke unpleasant odor decreased by about 12%, and a side stream smoke containing degree increased by about 14%, compared with the first comparative example, and it was confirmed that the side stream smoke generated when the cigarette in which ethyl vanillin was added to the wrapper of the smoking material was smoked was not reduced in taste, but improved in the preferable direction as shown in the first example.
In the case of the second embodiment, it was confirmed that the above-described side-stream smoke improvement effect was more remarkable as compared with the first embodiment. Specifically, the cigarettes of the second example had a significant effect in that the sweetness of the sidestream smoke increased by about 31% as compared to the first comparative example (by about 18% as compared to the first example) and the unpleasant smell of the sidestream smoke decreased by about 55% as compared to the first comparative example (by about 49% as compared to the first example), and the sidestream smoke content also increased by about 34% as compared to the first comparative example (by about 17% as compared to the first example), and thus it was confirmed that the sidestream smoke was improved in all sidestream smoke evaluation indexes in the desired direction.
On the other hand, as shown in fig. 9, it was found that the sensory characteristic evaluation results of the taste of the cigarettes of the first and second examples were improved compared with the first comparative example in most of the evaluation indexes.
Specifically, in the case of the cigarettes of the first example, the taste was improved in the preferred direction compared to the first comparative example, and in particular, it was confirmed that the taste intensity was increased by about 19% during smoking, the swallowing was increased by 16% during smoking, and the taste was slightly increased during smoking.
Further, in order to minimize the heterogeneous feeling with the existing tobacco, experiments were conducted by slightly conservatively setting the physical property values of the smoking material wrapper in the smoking article of the first embodiment for sensory property evaluation of fig. 8 and 9, but when the basis weight of the smoking material wrapper and the addition amount of ethyl vanillin were increased as compared with the first embodiment, it was predicted that more excellent sensory properties were exhibited in terms of the side stream smoke improvement effect.
In the case of the cigarettes of the second example, the blended taste was reduced by about 4% in smoking, the off-taste was increased by about 7% in smoking, but the taste intensity was increased by about 22% in smoking, the swallowing was increased by about 25% in smoking, and the fresh taste was increased by about 28% or more in smoking, compared with the first comparative example, so that it was confirmed that the taste characteristics were improved in the preferential direction as a whole as well as the improvement in the sidestream smoke.
As described above, according to the smoking article and the smoking article housing including the same of the embodiment of the present invention, the flavor including the first flavor material such as ethyl vanillin and the like (and the second flavor material such as raspberry ketone and the like) is added to the smoking material wrapper so that the sidestream smoke generated in the smoking article can be improved, while the reduction in flavor upon smoking, which may occur due to the improvement of sidestream smoke, can be prevented.
