Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The advantages and features of the invention and the methods of accomplishing the same may be understood by reference to the drawings and the following detailed description of illustrative embodiments. However, the present invention is not limited to the embodiments described below, but can be implemented in various forms different from each other, and the embodiments are only for the purpose of fully disclosing the present invention so that a person having ordinary knowledge in the art to which the present invention belongs can fully understand the scope of the present invention, and the scope of the present invention is defined by the claims of the present invention. Like reference numerals refer to like elements throughout the specification.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used with the meaning commonly understood by one having ordinary skill in the art to which the present invention belongs. Furthermore, terms commonly used in dictionaries have a definition and are not interpreted abnormally or excessively without explicit special definition.

Also, as used herein, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the specification expressly states otherwise. The terms "comprises" and/or "comprising," when used in this specification, shall be taken to specify the presence of stated elements, steps, operations, and/or components, but do not preclude the presence or addition of one or more other elements, steps, operations, components, and/or groups thereof.

Terms used in this specification to represent an order such as "first", "second", and the like may be used to describe various constituent elements, but these constituent elements should not be limited by these terms. These terms are only used to distinguish one constituent element from another.

Throughout the specification, "smoking article" may refer to articles capable of generating an aerosol, such as cigarettes (cigarettes), cigars, etc. The smoking article may comprise an aerosol generating substance or an aerosol-forming substrate. Additionally, the smoking article may comprise a solid material based on tobacco raw materials, such as lamina tobacco, cut tobacco, reconstituted tobacco, and the like. The smoking material may include volatile compounds.

Further, throughout the specification, "upstream" or "upstream direction" refers to a direction away from the mouth of a user smoking the smoking article 100, while "downstream" or "downstream direction" refers to a direction closer to the mouth of a user smoking the smoking article 100. For example, in the smoking article 100 shown in figure 1, the smoking material portion 120 is located upstream or in an upstream direction of the filter mouth portion 110.

In the present description, 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 a gas mist generating device (not shown) such as an electronic cigarette device or the like.

Referring to fig. 1, a smoking article 100 may comprise: a filter mouth 110, surrounded by a filter wrapper 110 a; a smoking material section 120 wrapped with a smoking material wrapper 120 a; and a tipping paper 130 which joins the filter portion 110 and the smoking material portion 120.

The filter mouth 110 may be an area disposed downstream of the smoking material portion 120 and passing just before a user inhales aerosol material generated in the smoking material portion 120.

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

In some embodiments, the filter plugs 110 may be cellulose acetate filters that are not flavored with a flavoring material, although the invention is not limited in this regard and the filter plugs 110 may be Trans Jet Nozzle System (TJNS) filters that are flavored with a flavoring material.

In some embodiments, the filter mouth 110 may be a tubular structure that includes a cavity therein. In addition, the filter mouthpiece section 110 may be made by inserting structures such as membranes, tubes, etc. having the same or different materials into the interior (e.g., cavity).

On the other hand, the hardness of the filter unit 110 may be adjusted by adjusting the content of the plasticizer when the filter unit 110 is manufactured. Triacetin (triacetin) may be used as the plasticizer, and the content of triacetin may be 5% to 15% with respect to the total weight of the filter mouthpiece 110, but the type and content of the plasticizer are not limited thereto, and may be appropriately adjusted as needed.

The filter mouth portion 110 of the present embodiment is illustrated as a single filter made of a single filter, but the present invention is not limited thereto. For example, the filter unit 110 may be provided as a double filter or a triple filter having two acetate filters, to improve the filtering efficiency.

Further, although not shown in the drawings, a capsule (not shown in the drawings) may be contained inside the filter mouthpiece portion 110. The capsule has a structure in which a content solution containing a perfume is wrapped with a film, and for example, the capsule may have a spherical shape or a cylindrical shape. The diameter of the capsule may be approximately 2.6mm to 3.5mm, but the present invention is not limited thereto, and the diameter of the capsule may be different according to the specification of the smoking article 100.

The material forming the membrane of the capsule may be a natural material, starch and/or a gelling agent. For example, in the case of a membrane made of a natural material, the membrane may be composed of agar, pectin, sodium alginate, glycerin, and the like. Gellan gum or gelatin may be used as the gelling agent. In addition, the gelling aid may be further used as a material for forming a film of the capsule. Here, for example, calcium chloride may be used as a gelling aid. In addition, the plasticizer may be further used as a material for forming the film of the capsule. Here, glycerin and/or sorbitol may be used as the plasticizer. Also, the colorant may be further used as a material for forming a film of the capsule.

In some embodiments, as the solvent of the flavor of the content solution contained in the capsule, 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 content solution of the capsule may include flavors such as menthol and essential oils of plants, etc., but the present invention is not limited thereto.

The filter mouth 110 may be wrapped by a filter wrapper 110 a. In some embodiments, the filter wrapper paper 110a may be made of a paper wrapper having oil resistance. The filter wrapper 110a may be made of oil-resistant wrapping paper to prevent a capsule content solution released to the outside of the capsule from passing through the filter wrapper 110a by a smoker breaking the capsule contained in the filter plug 110. In some embodiments, the inner side of the filter wrapper 110a may further comprise aluminum foil.

The filter mouth portion 110 is arranged downstream of the smoking material portion 120 to act as a filter, with aerosol material passing through the filter mouth portion 10 just before a user inhales aerosol material generated in the smoking material portion 120.

The smoking material portion 120 may contain an aerosol generating substance. For example, the smoking material portion 120 may include tobacco cut filler. The smoking material portion 120 may have a long extended rod shape, and its length, circumference, and diameter may vary.

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.

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

In some embodiments, the smoking material portion 120 may comprise reconstituted tobacco material formed by: the tobacco raw material is mixed with a solvent and various additives after grinding it to make a slurry shape, and then dried to form a sheet, which is processed to be formed into a block shape such as 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., 12mm) in length, about 0.8mm to 1.2mm (e.g., 1mm) in width, and about 0.08mm to 0.12mm (e.g., 0.1mm) in thickness, although the invention is not limited thereto.

By making the smoking material portion 120 include a plurality of thread-like materials processed into a wide tobacco sheet shape, the density of the tobacco material filled in the smoking material portion 120 can be increased, so that the amount of aerosol generation can be increased, and the smoking characteristics of the smoking material portion 120 can be improved.

The smoking material portion 120 may be wrapped by a smoking material wrapper 120 a.

In some embodiments, the smoking material wrapper 120a may include a filler (filler), which may increase the opacity of the smoking material wrapper 120a or impart porosity thereto, and may improve the smoothness and soot integrity of the cigarette paper, and may also increase the whiteness of the cigarette paper. As the above filler, materials such as calcium carbonate, titanium dioxide, magnesium oxide, and the like can be used, but the present invention is not limited thereto.

Also, although not shown in the drawings, the smoking material wrapper 120a may have a double roll paper structure. Specifically, the smoking material wrapper 120a may include an inner wrapper (not shown) attached to the smoking material portion 120 and wrapping the smoking material portion 120, and an outer wrapper (outer wrapper) attached to the inner wrapper and wrapping the outer portion of the inner wrapper.

The filter portion 110 wrapped with the filter wrapper 110a and the smoking material portion 120 wrapped with the smoking material wrapper 120a may be jointly wrapped by tipping paper 130. That is, the tipping wrapper 130 may wrap around at least a portion (e.g. a downstream portion region) of the smoking material wrapper 120a and the periphery of the filter wrapper 110 a. In other words, at least a portion of the smoking material portion 120 and the filter portion 110 may be further wrapped and physically bonded by the tipping paper 130.

In some embodiments, the tipping paper 130 may be made of non-porous roll paper that has not been subjected to oil resistance treatment, but the invention is not limited thereto.

Tipping paper 130 may be coated with a sweetener such as sucralose and citric acid. Also, a predetermined material may be added to the tipping paper 130. An example of the predetermined material may be silicon (silicone), but the present invention is not limited thereto. For example, silicon has various 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 paper 130 even if it is not silicon, without limitation.

The tipping paper 130 prevents the filter plug 110 from burning. For example, when the smoking material portion 120 is combusted to a portion adjacent to the filter portion 110, the filter portion 110 may also be combusted. Even in this case, since the tipping paper 130 includes a noncombustible material, it is possible to prevent the phenomenon in which the filter portion 110 burns.

On the other hand, in the production of the smoking material wrapper 120a, various attempts have been made to include a filler in the smoking material wrapper 120a, to form a double-rolled structure, or to use a water-soluble flavor carrier including a flavor, in various compositions and manners as described above, in order to reduce the smoke smell caused by smoke generated by smoking. However, even when the sidestream smoke reduction effect of the above-described various attempts is made, since the tipping paper 130 is not the smoking material wrapping paper 120a but a portion which the fingers of the smoker who smokes smoke directly contacts, a finger smoke reduction technique which is not applied to the smoking material wrapping paper 120a but is directly applicable to the tipping paper 130 is required in order to effectively reduce the finger smoke.

In this regard, the tipping paper 130 of the present invention comprises a perfume carrier composed of a perfume material for masking the smoke smell and a carrier material for inclusion (inclusion) of the above perfume material. The flavourant carrier may be included in the tipping paper for a smoking article described above by a tipping paper flavourant carrier printing process using a flavourant carrier ink composed of ethanol, the flavourant material described above and the carrier material described above.

The fragrance-carrying ink can be prepared by adding a carrier material, a fragrance material, and a binder to ethanol in this order and stirring them. Specifically, the fragrance carrier ink can be prepared by the following steps: step i) adding the support material in ethanol and stirring for about 30 to 60 minutes; step ii) adding a perfume material to the ethanol solution with the added carrier material and stirring for about 15 to 45 minutes; and step iii) adding a binder to the ethanol solution with the carrier material and the perfume material added thereto and stirring for about 15 minutes to 45 minutes.

When the above perfume carrier ink includes microcapsules to be described below, the above step iii) may further include: step iv) adding the microcapsules to the ethanol solution with the added carrier material, perfume material and binder and stirring for 15 to 45 minutes.

The above-described fragrance carrier printing process may be achieved by mixing the above-described fragrance carrier in the ink used when subjecting the tipping paper to an overprint varnish (OPV) process, but preferably, a printing process separate from the above-described OPV process may be performed after the above-described OPV process to maximize the fragrance loading delivered to the tipping paper.

In some embodiments, the fragrance carrier ink described above can further include a binder and/or microcapsules, details regarding which will be described below.

The carrier material in the present invention is characterized by being a material that is insoluble in water, isopropyl alcohol, or the like, but soluble in ethanol. For example, the carrier material may be 2-hydroxypropyl- β -cyclodextrin (2-hydroxypropyl- β -cyclodextrin).

This is because it is practically impossible to apply the manner of applying the water-soluble flavor carrier material (e.g., β -cyclodextrin) that includes the flavor material in the smoking material wrapper 120a described above directly to the tipping paper 130 that must accompany the printing and drying process. Specifically, when the above-described water-soluble perfume carrier system is applied to the tipping paper 130, it is necessary to use water as an ink solvent, and in this case, the surface energy of the ink is increased to about 70mN/m to 75mN/m, which causes difficulty in a drying process after printing the tipping paper 130, and may cause problems such as contamination of the tipping paper, ink falling due to weakening of the bonding force between the printed ink and the tipping paper, and the like. Further, when the drying temperature is raised or the drying time is increased in order to dry the ink whose surface energy is increased, curl (curl) of the tipping paper increases. In contrast, when the flavor material is printed on the tipping paper without using the above-described carrier system, the flavor material disappears to the outside of the smoking article during storage of the tipping paper due to the characteristics of the tipping paper disposed at the outermost periphery of the smoking article, or the problem of discoloration of the tipping paper occurs depending on storage conditions such as light and humidity.

In contrast, according to the present invention, when a hydrophobic flavor material is included in a carrier material suitable for a tipping paper, and a polymer material such as 2-hydroxypropyl- β -cyclodextrin or the like soluble in ethanol is used as the carrier material, ethanol can be used as an ink solvent, so that an ink having a surface energy of the order of about 20mN/m to 50mN/m can be used, and thus a printing and drying process of the tipping paper can be applied, whereby not only the manufacturing workability of a smoking article can be ensured, but also storage stability can be ensured since there is no discoloration problem.

On the other hand, the above-mentioned flavor material included in the above-mentioned carrier material is expressed to the outside of the above-mentioned tipping paper 130 (i.e., the outside of the smoking article 100) in response to moisture, saliva (saliva), or friction, and the expressed flavor material is transferred to the fingers of the smoker who grips the tipping paper portion, thereby possibly serving to mask the finger smoke smell.

Further, the flavor material is not expressed until moisture or saliva (e.g., saliva) of the smoker is transferred to the tipping paper or rubbed by the smoker (e.g., the smoker grasps or rubs the tipping paper), and thus, the problem of loss of the flavor due to the lapse of the storage period or the problem of generation of unnecessary flavor in a state where the smoker simply stores the smoking material can be solved.

The above perfume material included in the carrier material may comprise at least one of vanillin (vanillin) and ethyl vanillin (ethyl vanillin).

On the other hand, as will be described hereinafter with reference to tables 7 to 8, the total weight ratio of the above vanillin and ethyl vanillin considering the problem of discoloration of the tipping paper may be greater than 0% and equal to or less than 50% relative to the total weight of the above perfume material. Preferably, the weight ratio of vanillin may be greater than 0% and equal to or less than 30%, and the weight ratio of ethyl vanillin may be greater than 0% and equal to or less than 20%, relative to the total weight of the above-mentioned perfume material. More preferably, the weight ratio of the vanillin may be approximately 15% to 25% and the weight ratio of the ethyl vanillin may be approximately 5% to 15% with respect to the total weight of the perfume material.

The above perfume material may include various ingredients other than the above vanillin and ethyl vanillin, and table 1 shows ingredients of perfume materials that have been confirmed to achieve the above finger smoke reduction effect maximization.

TABLE 1

In some embodiments, the flavor material may have a composition ratio in the order of ROSEMARY OIL (rosemate OIL), vanillin, fermented alcohol, lavandula OIL (LAVANDIN OIL), ethyl vanillin, and eucalyptus OIL (EUCALYPTOL). The content ratio of the vanillin to the eucalyptus oil contained in the spice material is about 2.5: 1 to 3.5: 1 (preferably about 3: 1), and the content ratio of the ethyl vanillin and the lavandula angustifolia oil contained in the perfume material is about 0.5:1 to 1.5:1 (preferably about 1:1), but the present invention is not limited thereto.

On the other hand, when more perfume material than the required amount is contained in the perfume carrier ink, there may be a problem that perfume is transferred to other tipping papers than the tipping paper of the present invention to which perfume should not be applied in a mass production process, and discoloration may occur during preservation after preparation of the tipping paper.

In order to solve the above problem, the weight ratio of the fragrance material may be substantially greater than 0% and equal to or less than 3%, and the weight ratio of the carrier material may be substantially greater than 0% and equal to or less than 30%, with respect to the total weight of the fragrance-carrying ink. Preferably, the weight ratio of the fragrance material may be substantially greater than 0% and equal to or less than 1.5%, and the weight ratio of the carrier material may be substantially greater than 0% and equal to or less than 15%, relative to the total weight of the fragrance carrier ink. More preferably, the weight ratio of the fragrance material may be approximately 0.4% to 1.3% and the weight ratio of the carrier material may be approximately 5% to 10% relative to the total weight of the fragrance-carrying ink.

The binder that may be included in the above-described fragrance carrier ink may be an acrylic acid and starch-based polymer that is soluble in ethanol. By including a binder that can be contained in the above-described perfume carrier ink, the tipping paper residual amount of the perfume material included in the perfume carrier can be increased. That is, the flavourant material or flavourant carrier, which may disappear during storage after preparation of the smoking article, may be better stored in the tipping paper by the binder.

On the other hand, in order for the adhesive to function as a means for preserving the above-mentioned perfume material while ensuring printing workability, the adhesive needs to have an appropriate viscosity, and for this reason, the above-mentioned adhesive has a molecular weight of about 1000 to 30000 and a glass transition temperature (glass transition temperature) of about 50 ℃ to 100 ℃. Preferably, the above binder may be a polymer material having a molecular weight of about 3000 to 20000 and a glass transition temperature of about 60 to 90 ℃. This is because if the viscosity of the binder is too low, the ink flows down, and if the viscosity is too high, the ink becomes rigid, which lowers workability, and the inherent performance of the binder may also be lowered.

Also, as will be described in greater detail below with reference to table 4, as binder loading increases, flavor retention tends to increase, but when binder loading is too great, tipping paper curl increases, and difficulties may arise in making the smoking article.

In order to solve the above-mentioned difficulties, the weight ratio of the binder may be substantially more than 0% and equal to or less than 15% with respect to the total weight of the fragrance carrier ink. Preferably, the weight ratio of the binder may be approximately 5% to 10% with respect to the total weight of the fragrance carrier ink.

The microcapsules that may be included in the fragrance carrier ink may include polyvinyl alcohol (PVA), a fragrance, and a cross-linking agent. Specifically, the core (core) of the above-mentioned microcapsule may be an ethanol-based perfume, the shell (shell) may be polyvinyl alcohol, and sodium sulfate (Na) may be used₂SO₄) As a cross-linking agent. The perfume may be an ethanol-based perfume. The microcapsules may have a diameter of approximately 1.5 μm to 5.0 μm.

In some embodiments, the perfume may have the same composition as the perfume material included in the perfume carrier material.

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

In some embodiments, the weight ratio of the microcapsules may be substantially greater than 0% and equal to or less than 25%, preferably, may be substantially 5% to 20%, relative to the total weight of the fragrance-carrying ink. Thus, it is possible to solve the problem of over-expression of aroma before smoking and/or the problem of the surface of the tipping paper being contaminated and roughened by the capsule shell, which may occur due to over-inclusion of microcapsules.

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

The microcapsules can be prepared by the following steps: step i) stirring the ethanol-based fragrance and polyvinyl alcohol at room temperature for approximately 15 minutes to 45 minutes; step ii) adding a crosslinking agent to a solution obtained by stirring an ethanol-based fragrance and polyvinyl alcohol so that the content of the crosslinking agent is about 30% relative to the polyvinyl alcohol, and stirring the mixture at a temperature of 60 ℃ or higher and 100 ℃ or lower for about 5 hours to 10 hours; and step iii) cooling the solution of ethanol-based flavorant, polyvinyl alcohol, and cross-linking agent at room temperature for about 30 minutes to 2 hours.

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.

The tipping paper material of comparative example 1, which had undergone the OPV printing process and the drying process, was subjected to a printing process using an ink including a water-soluble flavor carrier including a flavor material, and then to a drying process at a drying speed of about 150 m/min. In the above-described water-soluble fragrance carrier printing process, water was used as a solvent, and a fragrance carrier ink containing about 1.25% of the fragrance material of table 1 above, about 9% of β -cyclodextrin (β -cyclodextrin), and about 5% of a water-soluble binder was used.

Comparative example 3

The tipping paper material of comparative example 2, which was subjected to the printing process using the ink including the water-soluble fragrance carrier, was subjected to the drying process at a drying speed of about 10 m/min.

Example 1

After the cigarette carrier printing process of the present invention was performed on the tipping paper material of comparative example 1 which had undergone the OPV printing process and the drying process, the drying process was performed at a drying speed of about 150 m/min. In the above fragrance vehicle printing process, ethanol was used as a solvent, and a fragrance vehicle ink containing about 1.25% of the fragrance material of table 1 above, about 9% of 2-hydroxypropyl- β -cyclodextrin (2-hydroxypropyl- β -cyclodextrin), and about 5% of a binder was used.

Experimental example 1 evaluation of drying and curling characteristics of tipping paper after printing

In order to confirm the drying and curl (curl) characteristics after printing of the tipping papers prepared according to the examples of the present invention, the surface energy of the ink, the dissolution degree of the perfume carrier, the drying degree of the ink, and the curl of the tipping paper applied in the printing of each of the examples and comparative examples were analyzed, and the results thereof are shown in table 2.

TABLE 2

As shown in table 2, the degree of dissolution of the fragrance vehicle was good in all of example 1, comparative examples 2 and 3. However, the tipping paper in comparative example 2 to which the printing with the water-soluble fragrance carrier was applied was confirmed to be incompletely dried after the printing and drying processes due to the use of water as an ink solvent at the time of printing with the water-soluble fragrance carrier, thereby giving the surface energy of the ink a high value of 72.4 mN/m. Although the tipping paper of comparative example 3 in which the drying rate was reduced to 10 m/min in order to completely dry the ink using water as a solvent exhibited a good degree of ink drying, a high value of about 12mm of tipping paper curl was generated, and it was confirmed that the tipping paper of comparative example 3 was not suitable for mass production of cigarettes.

In contrast, the tipping paper of example 1 using ethanol as an ink solvent and using a flavor carrier and a binder had good ink drying degree, and the tipping paper curl thereof was not significantly different from the value of comparative example 1 not using a flavor carrier printing process, and thus it was confirmed that the tipping paper of example 1 was not unreasonable for mass production process of cigarettes.

Example 2

The tipping paper of the cigarettes prepared in the examples for the purpose of the experiment was removed to separate the media portion and the filter mouth portion. A tipping paper having a porosity of about 100CU, prepared by applying the OPV process and a flavourant carrier printing process using an ethanol-based flavourant carrier ink containing 0.4% flavourant material, combines the separated media portion and filter mouthpiece, thereby preparing a smoking article.

Example 3

A smoking article was prepared in the same manner as in example 2, except that the ethanol-based flavourant-carrier ink contained 0.7% flavourant material.

Example 4

A smoking article was prepared in the same manner as in example 2, except that the ethanol-based flavourant-carrier ink contained 1.25% flavourant material.

Example 5

A smoking article was prepared in the same manner as in example 2, except that the ethanol-based flavourant-carrier ink contained 1.5% flavourant material.

Comparative example 4

Unlike examples 2 to 5, a smoking article was prepared in the same manner as in example 2, except that the flavor printing process was performed by stirring in ink in a state where the flavor material was not made into a carrier.

Experimental example 2 evaluation of finger odor reduction index substance of tipping paper-No adhesive used

In order to measure the finger odor reducing effect when smoking the cigarettes according to the examples and comparative examples, the change in vanillin and ethyl vanillin content of the smoke trapped from the tipping paper was analyzed, and the results thereof are shown in table 3.

The smoking articles according to the examples and comparative examples were each smoked in a state of 2 weeks after the preparation, and as smoking conditions, the smoking amount was set to 55ml, the smoking time was set to 2 seconds, the smoking cycle was set to 20 seconds, and the number of puffs was set to 12 times, and for the content analysis of vanillin and ethylvanillin, the smoke trapped after wrapping the tipping paper 130 with Cambridge Filter Pad (CFP) was analyzed by Gas Chromatography (GC).

TABLE 3

As shown in table 3, vanillin and ethyl vanillin components were detected in all the examples, and it was confirmed that the detected vanillin and ethyl vanillin components can act to mask the odor by contact with a finger. On the other hand, referring to the analysis results of example 4 and comparative example 4, it was confirmed that even if the content of the fragrance material in the ink was the same, more vanillin and ethyl vanillin components were detected in the case of performing the fragrance carrier printing by enclosing the fragrance material in the carrier material (example 4) as compared with the case of performing the fragrance printing in a state where the fragrance material is not supported (comparative example 4).

Further, referring to the analysis results of examples 2 to 5, as the content of the perfume material in the perfume carrier ink increases, the amounts of vanillin and ethylvanillin components expressed in the tipping paper tend to increase. However, in the case of example 5 in which the content of the flavorant material in the carrier was 1.5%, the problem occurred that the flavorant was transferred to the tipping paper other than the tipping paper of the present invention to which the flavorant should not be applied in the mass production process, and it was confirmed that example 4 in which the content of the flavorant material in the carrier was 1.25% had an excellent effect of reducing the finger odor due to smoking and was within a range in which mass production of cigarettes could be achieved.

Example 6

A smoking article was prepared in the same manner as in example 4 described with reference to table 3, except that 1.0% binder was included in the ethanol-based flavor carrier ink. A polymeric material having a molecular weight of about 18000 and a glass transition temperature of about 80 ℃ is used as the binder.

Example 7

A smoking article was prepared in the same manner as in example 6, except that the ethanol-based flavourant-carrier ink contained 3.0% binder.

Example 8

A smoking article was prepared in the same manner as in example 6, except that the ethanol-based flavourant-carrier ink contained 5.0% binder.

Example 9

A smoking article was prepared in the same manner as in example 6, except that the ethanol-based flavourant-carrier ink contained 15.0% binder.

Experimental example 3 evaluation of finger odor reduction index substance of wrapping paper-applicable adhesive

In order to measure the finger odor reducing effect when smoking the cigarettes according to the examples and comparative examples, the change in vanillin and ethyl vanillin content of the smoke trapped from the tipping paper was analyzed, and the results thereof are shown in table 4.

TABLE 4

As shown in table 4, as the binder content in the fragrance carrier ink increased, the amount of vanillin and ethyl vanillin components expressed in the tipping paper tended to increase. However, in the case of example 9 in which the binder content was 15%, a problem of excessive increase in tipping paper curl occurred, and it was confirmed that when the binder content was 5% to 10%, the finger odor reduction effect due to smoking was excellent and the tipping paper curl problem could also be solved.

Example 10

A smoking article was prepared in the same manner as in example 8 described with reference to table 4, except that 5.0% microcapsules were contained in the ethanol-based flavor carrier ink. The microcapsules used are those consisting of a core of an ethanol-based perfume and a shell of polyvinyl alcohol, and having a diameter of about 1.5 to 5.0 μm using sodium sulfate as a cross-linking agent.

Example 11

A smoking article was prepared in the same manner as in example 10, except that the ethanol-based flavourant-carrier ink contained 10.0% binder.

Example 12

A smoking article was prepared in the same manner as in example 11, except that the ethanol-based flavourant-carrier ink contained 15.0% microcapsules.

Example 13

A smoking article was prepared in the same manner as in example 12, except that the ethanol-based flavourant-carrier ink contained 25.0% microcapsules.

Experimental example 4 evaluation of finger odor reduction index substance of wrapping paper-suitable adhesive and microcapsule

In order to measure the finger odor reducing effect when smoking the cigarettes according to the examples and comparative examples, the change in vanillin and ethyl vanillin content of the smoke trapped from the tipping paper was analyzed, and the results thereof are shown in table 5.

TABLE 5

As shown in table 5, as the content of microcapsules in the fragrance carrier ink increased, the amount of vanillin and ethyl vanillin components expressed in the tipping paper tended to increase. However, in the case of example 13 in which the content of microcapsules was 25%, the intensity of the outer fragrance occurring in the cigarette in a preserved state before smoking was excessively increased, and the surface contamination of the tipping paper occurred due to the breakage of the microcapsules, so that it was confirmed that when the content of microcapsules was 10% to 20%, the finger odor reducing effect due to smoking was excellent, and the problems of the intensity of the outer fragrance and the surface contamination of the tipping paper could be solved.

Experimental example 5 evaluation of printing workability/subsequent Process workability of tipping paper

In order to confirm the printing workability of the tipping paper prepared according to the example of the present invention and the workability characteristics of the subsequent processes for preparing cigarettes after printing, physical characteristics of the tipping paper were analyzed, and the results thereof are shown in table 6. The physical characteristics of the tipping papers in experimental example 5 were analyzed with each tipping paper before assembly to the smoking articles of examples 8 and 10 to 12 as an evaluation target.

TABLE 6

As shown in table 6, it is understood that each of examples 8 and 10 to 12 exhibits good printing workability of the tipping paper, and no adhesion problem between the front and rear faces of the tipping paper which may occur due to transfer of Ink to the rear face caused by rolling of the paper in a state in which the Ink (Ink) is not completely dried occurs, and further, no problem of serious slippage or excessive roughness of the surface due to smoothness of the surface of the tipping paper occurs, the slippage is good, and the tipping paper curls within an appropriate numerical range. It was confirmed from this that there was no problem in the printing workability of the fragrance vehicle using the fragrance vehicle ink including the fragrance material, the binder and the microcapsule within the range of the above-mentioned examples.

Example 14

The tipping paper of the cigarettes prepared in the examples for the purpose of the experiment was removed to separate the media portion and the filter mouth portion. A tipping paper having a porosity of about 100CU, prepared by applying the OPV process and a flavourant carrier printing process using an ethanol-based flavourant carrier ink containing 1.25% flavourant material, combines the separated media portion and filter mouth portion, thereby preparing a smoking article. Wherein the perfume material contains 5% vanillin and 10% ethyl vanillin.

Example 15

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

Example 16

A smoking article was prepared in the same manner as in example 14, except that 20% vanillin was contained in the flavor material.

Example 17

A smoking article was prepared in the same manner as in example 14, except that 30% vanillin was contained in the flavor material.

Example 18

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

Comparative example 5

Unlike examples 13 to 17, smoking articles were prepared in the same manner as in example 15, except that the flavor printing process was performed by stirring in ink in a state where the flavor material was not made into a carrier.

Experimental example 6 evaluation of color stability according to changes in the content of vanillin in perfume Material

In order to evaluate the color stability evaluation of the tipping paper according to the change in the vanillin content in the flavor material, the degree of color change of the cigarette immediately after the preparation and the cigarette after 2 months from the preparation was quantified by the color difference (Δ E) of the CIELAB color space, and is shown in table 7. The cigarettes were stored for 2 months at a temperature of about 40 ℃ and a relative humidity of about 60%.

TABLE 7

Referring to the analysis results of examples 13 to 17, it was confirmed that as the vanillin content in the perfume material increased (the ethyl vanillin content was fixed to 10%), the degree of discoloration of the tipping paper also increased. In particular, it was found that the degree of discoloration sharply increased to a value that was observable with the naked eye in examples 16 and 17 having a vanillin content of 30% or more, and that the degree of discoloration of the tipping papers was very slight in examples 13 to 15 having a vanillin content of 5% to 20%. Further, referring to the analysis results of example 15 and comparative example 5, it was confirmed that even if the content of vanillin and ethyl vanillin in the fragrance material was the same, the degree of discoloration was smaller in the case of performing fragrance carrier printing by enclosing the fragrance material in the carrier material (example 15) than in the case of performing fragrance carrier printing without making the fragrance material carrier (comparative example 5).

Example 19

Smoking articles were prepared in the same manner as in example 14 described with reference to table 7, except that 20% vanillin and 5% ethyl vanillin were included in the flavour material.

Example 20

A smoking article was prepared in the same manner as in example 19, except that 20% ethyl vanillin was contained in the flavour material.

Example 21

A smoking article was prepared in the same manner as in example 19, except that 30% ethyl vanillin was contained in the flavour material.

Example 22

A smoking article was prepared in the same manner as in example 19, except that 40% ethyl vanillin was contained in the flavour material.

Experimental example 7 evaluation of color stability according to changes in Ethyl Vanillin content in fragrance Material

In order to evaluate the color stability of the tipping paper according to the change in the ethyl vanillin content in the flavor material, the degree of color change of the cigarette immediately after the preparation and the cigarette after 2 months from the preparation was quantified by the color difference of CIELAB color space, and is shown in table 8. The cigarettes were stored for 2 months at a temperature of about 40 ℃ and a relative humidity of about 60%.

TABLE 8

Similarly to experimental example 6, it can be confirmed with reference to the analysis results of examples 18 to 21 that as the content of ethyl vanillin in the perfume material increases (the content of vanillin is fixed at 20%), the degree of discoloration of the tipping paper also increases. In particular, it was found that the degree of discoloration sharply increased to a value that was observable with the naked eye in examples 19 to 21 having an ethyl vanillin content of 20% or more, and that the degree of discoloration of the tipping papers was very slight in examples 15 and 18 having an ethyl vanillin content of 5% to 10%.

Experimental example 8 sensory evaluation of smoking of tipping paper Using flavor Carrier

In order to confirm the sensory properties of the tipping paper to which the flavor carrier of the present invention was applied, sensory evaluations were performed on the intensity of the outer flavor, the intensity of the cigarette flavor, the intensity of the finger smoke flavor after smoking, the intensity of the fragrance remaining in the finger after smoking, and the degree of satisfaction of the fragrance remaining in the finger of the smoking articles according to example 1, comparative example 1, and comparative example 4.

The smoking articles of example 1, comparative example 1 and comparative example 4 were used to evaluate sensory properties of 20 panelists, and the panelists were scored based on an 8 point full score.

Figure 2 is a sensory evaluation of smoking for smoking articles prepared according to example 1, comparative example 1 and comparative example 4 and stored at room temperature for 2 weeks, and figure 3 is a sensory evaluation of smoking for smoking articles prepared according to example 1, comparative example 1 and comparative example 4 and stored at room temperature for 2 months.

Referring to fig. 2 and 3, the cigarette of comparative example 4 to which flavor printing was applied had a significantly increased outer flavor intensity (i.e., flavor intensity in a state before being rubbed with tipping paper by a smoker's fingers and transferring saliva from the smoker's mouth) as compared to the cigarette of comparative example 1 to which flavor printing was not applied. In contrast, in the case of the cigarette of example 1 to which the flavor carrier printing was applied, the intensity of the outer fragrance was increased as compared with the cigarette of comparative example 1, but had a significantly lower value of intensity of the outer fragrance as compared with comparative example 4.

The intensity of fragrance remaining on the fingers after smoking was confirmed to be greatly increased in comparative example 4 and example 1 as compared with comparative example 1, and slightly increased in example 1 as compared with comparative example 4. The intensity of finger smoke after smoking was confirmed to be reduced in comparative example 4 and example 1, and in example 1 in comparison with comparative example 4.

Considering that the value of the intensity of the external fragrance in example 1 is lower than that in comparative example 4, and the intensity of the fragrance remaining in the fingers after smoking in example 1 is higher than that in comparative example 4, it was confirmed that the expression amount of the fragrance before smoking in the case of printing with the fragrance material being carried in a vehicle (example 1) is relatively decreased and the expression amount of the fragrance at the time of smoking is relatively increased, as compared with the case of not applying the vehicle (comparative example 4).

Since there was no great difference in the flavor intensity among the cigarettes of example 1, comparative example 1, and comparative example 4, it was predicted that the smoking sensation was not reduced by applying perfume printing.

Experimental example 9 sensory evaluation of smoking Using microcapsules additionally applied

In order to confirm the changes in sensory properties depending on whether or not microcapsules are added, sensory evaluations were performed on the intensity of the outer fragrance, the intensity of the taste of the cigarette, the intensity of the smoke smell of the finger after smoking, the intensity of the fragrance remaining in the finger after smoking, and the degree of satisfaction of the fragrance remaining in the finger of examples 10 to 12 and comparative example 1. The smoking articles of examples 10 to 12 and comparative example 1 were used to evaluate the sensory properties of 20 panelists, and the scores were scored on the basis of an 8-point full score.

Fig. 4 is sensory evaluation results of smoking for smoking articles prepared according to examples 10 to 12, comparative example 1, and then for 2 weeks.

Referring to fig. 4, as the content of the binder and/or the microcapsule in the fragrance vehicle ink increases, the intensity of the fragrance remaining on the fingers after smoking, and the satisfaction of the fragrance remaining on the fingers generally increase, and the intensity of the finger smoke after smoking tends to decrease.

In examples 10 to 12, it was confirmed that the increase in the intensity of fragrance remaining on the fingers after smoking was larger than that in comparative example 1, and it was found that in examples 10 to 12, the fragrance was not substantially expressed when the cigarette was stored, but the fragrance was substantially expressed by the smoking behavior of the smoker.
