Description

Fragrance-containing sheet for smoking article comprising modified cellulose and smoking article comprising the same

The present disclosure relates to a perfume-containing sheet for smoking articles comprising modified cellulose and smoking articles comprising the same.

[0003] In order to generate a specific flavor in a smoking article, a method is employed in which a flavoring component is added to the tobacco in a solution state. This method has the advantage that the flavoring solution can be simply added to tobacco by spraying or the like. However, if the added amount of the fragrance is increased to release the fragrance during smoking, the amount of solvent increases, which tends to cause stains on the cigarette paper. In addition, since it is difficult to continuously express flavoring substances during smoking, there is a disadvantage in that the flavor weakens in the latter half of smoking.

1 is a diagram schematically illustrating a configuration of a smoking article 100 according to an example.

A smoking article 100 may include a first portion 110 comprising tobacco elements and a second portion 120 comprising filter elements.

Referring to FIG. 1 , the first portion 110 and the second portion 120 may be sequentially aligned in the longitudinal direction of the smoking article 100 . Here, the length direction of the smoking article 100 may be the direction in which the length of the smoking article 100 extends. For example, the lengthwise direction of the smoking article 100 may be from the first portion 110 toward the second portion 120 .

The first portion 110 may include tobacco elements. The tobacco component may be any form of tobacco material. For example, the tobacco component may take the form of tobacco cut filler, tobacco particles, tobacco sheets, tobacco beads, tobacco granules, or tobacco extract. In addition, the tobacco material may include, for example, one or more of tobacco leaves, tobacco side veins, puffed tobacco, cut cut filler, sheet leaf cut filler, and reconstituted tobacco.

The second portion 120 may include a single segment of a filter element. The filter element may be a cellulose acetate filter. The shape of the filter element is not limited. For example, the filter element may be a cylindrical rod or a tubular rod having a hollow therein. Also, the filter element may be a rod of recess type.

The second portion 120 may be manufactured to generate flavor. As an example, flavoring liquid may be sprayed onto the second part 120 , or a separate fiber coated with flavoring liquid may be inserted into the second part 120 .

Also, the second part 120 may include at least one capsule 130 . Here, the capsule 130 may function to generate a flavor or generate an aerosol. For example, the capsule 130 may have a structure in which a liquid containing a fragrance is wrapped in a film. The capsule 130 may have a spherical or cylindrical shape, but is not necessarily limited thereto.

Also, the second part 120 may include a plurality of segments. This embodiment will be described in more detail with reference to FIG. 1 .

The second part 120 may include a filter element 123 and may further include a cooling element 121 .

The cooling element 121 may cool airflow passing through the first portion 110 from the exterior of the smoking article 100 . The cooling element 121 may be a cylindrical paper tube made of paper and having a hollow core. In addition, the cooling element 121 may be made of a polymer material or a biodegradable polymer material, and may have a cooling function. For example, the cooling element 121 may be made of polylactic acid (PLA) fibers, but is not limited thereto. Also, the cooling element 121 may be made of a cellulose acetate filter in which a plurality of holes are drilled. However, the cooling element 121 is not necessarily limited to the above examples, and the present disclosure may include any material that performs a function of cooling air flow without limitation. In addition, the cooling element 121 may be a tube filter or branch tube including a hollow tube.

Additionally, although not shown in FIG. 1 , the smoking article 100 may further include a plug (not shown). A plug may be disposed at the distal end of the smoking article 100 .

At least one of the first to fourth wrappers may be a biodegradable wrapper. When biodegradable wrappers are used, the smoking article 100 can be rapidly degraded by microorganisms, thereby reducing environmental contamination.

2 is a schematic illustration of a smoking article 200 according to another example.

Referring to FIG. 2 , smoking article 200 may include a first portion 210 and a second portion 220 . The second portion 220 can include a single segment of filter element. For example, with respect to the second portion 220 , the above descriptions of the second portion 120 of FIG. 1 may be equally applied.

Referring to FIG. 2 , the first part 210 may be divided into two sections. The first portion 210 may include an aerosol-generating substrate 211 and a nicotine-generating substrate 213 .

When the nicotine-generating substrate 213 is heated, nicotine is generated from the nicotine-generating substrate 213 and nicotine may be transferred to the second part 220 .

Also, the second part 220 may include a plurality of segments. For example, the second part 220 may include a filter element 223 and may further include a cooling element 221 .

The cooling element 221 and the filter element 223 of FIG. 2 may be equally applied to the cooling element 121 and the filter element 123 of FIG. 1 described above. Therefore, overlapping contents are omitted.

A perfume-containing sheet for a smoking article according to the present disclosure can be included in, for example, a first portion 110, 210 or a second portion 120, 220 of a smoking article 100, 200 shown in FIGS. 1 and 2 .

To prepare a perfume-containing sheet for smoking articles according to the present disclosure, a slurry (or crude liquor) comprising all of distilled water, alcohol, modified cellulose, and perfume may be prepared. In addition, the slurry may further include a bulking agent, an aerosol former, or an emulsifier.

In the slurry, alcohol may be included by about 1 to 80 wt% based on the total slurry. When the alcohol is mixed into the slurry in a weight ratio within the aforementioned numerical range, the modified cellulose can be better dissolved.

More specifically, in the slurry, distilled water and alcohol may be mixed in a weight ratio of about 1:1 to about 10:1. Preferably, distilled water and alcohol may be mixed in a weight ratio of about 2.33:1. When distilled water and alcohol are mixed in a weight ratio within the aforementioned numerical range, the modified cellulose can be better dissolved.

Distilled water may be a factor in determining the viscosity of the slurry.

Alcohol can be utilized as a solvent. Alcohol may be, for example, ethanol. When ethanol is included in the slurry, modified cellulose such as HPMC, MC, CMC, or EC and flavoring ingredients such as L-menthol can be well dissolved in the slurry at room temperature.

Modified cellulose may be cellulose in which a specific functional group is substituted in the molecular structure. The modified cellulose may be, for example, hydroxypropyl methyl cellulose (HPMC), methyl cellulose (MC), carboxymethyl cellulose (CMC), or ethyl cellulose (EC). Hydroxypropyl methyl cellulose may have a grade in the range of about 4 to about 40000 depending on the ratio of hydroxypropyl groups and methyl groups (or methoxy groups) being substituted. Depending on the grade, the viscosity of hydroxypropyl methyl cellulose can be determined.

Modified cellulose, as a preferred example, may be Lotte Fine Chemical's product name AN6 / AN15 / AN50 / BN10 / BN50 / MC15 / MC50 and the like.

When MC15 or MC50 (cellulose substituted with a methyl group) is used as the modified cellulose, it has been confirmed that the perfume-containing sheet for smoking articles according to the present disclosure has excellent viscosity properties, slurry formation properties, drying properties, sheet physical properties, and fragrance retention properties. In such cases, the perfume-containing sheet for smoking articles may have a viscosity within the range of about 100 to about 10,000 cp when formulated as a slurry.

Fragrances include, for example, menthol, leaf tobacco extract, natural vegetable flavorings (eg, cinnamon, sage, herbs, chamomile, galweed, persimmon tea, cloves, lavender, cardamom, cloves, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon, caraway, jasmine, Ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang-ylang, fennel, anise, licorice, St. John's bread, plum extract, peach extract, etc.), sugars (e.g., glucose, fructose, isomerized sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (e.g. For example, isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (eg, menthone, ionone, damacenone, ethylmaltol, etc.), alcohols (eg, geraniol, linalol, anethol, eugenol, etc.), aldehydes (eg vanillin, benzaldehyde, anisaldehyde, etc.), lactones (eg, γ -undecalactone, γ-nonalactone, etc.), animal-based spices (eg, musk, ambergris, civet, castrum, etc.), hydrocarbons (eg, limonene, pinene, etc.). The fragrance may be used as a solid or dissolved or dispersed in an appropriate solvent such as propylene glycol, ethyl alcohol, benzyl alcohol, or triethyl citrate. In addition, "spice" which is easily formed in a dispersed state in a solvent by the addition of an emulsifier, for example, a hydrophobic "spice" or an oil-soluble "spice" can be used. These fragrances may be used alone or as a mixture. However, the present disclosure is not necessarily limited to the foregoing, and the present disclosure may include any flavor used in smoking articles.

The bulking agent may serve to increase the volume of the spice-containing sheet produced by increasing the total mass (ie, dry matter mass) of components other than water in the raw material slurry. The bulking material is a material that serves only to increase the volume of the spice-containing sheet and does not affect the original function of the spice-containing sheet. Specifically, the bulking material only serves to increase the volume of the spice-containing sheet, and the bulking material may have properties that do not adversely affect the spice retention function of the spice-containing sheet without substantially increasing the viscosity of the raw material slurry.

The bulking material may preferably be starch or starch hydrolyzate. A starch hydrolyzate means a substance obtained by a process including a process of hydrolyzing starch. The starch hydrolyzate is, for example, a substance obtained by directly hydrolyzing starch (namely, dextrin) or a substance obtained by hydrolyzing starch after heat treatment (namely, indigestible dextrin). The bulking material may be, for example, dextrin, and more specifically cyclodextrin.

The starch hydrolyzate may generally be a starch hydrolyzate having a DE value in the range of about 2 to about 40, preferably a starch hydrolyzate having a DE value in the range of about 2 to about 20. As a starch hydrolyzate having a DE value in the range of about 2 to about 20, for example, Finex #100 (Matsutani Chemical Co., Ltd.), Fine Fiber (Matsutani Chemical Co., Ltd.), TK-16 (Matsutani Chemical Co., Ltd.) can be utilized.

DE is an abbreviation of dextrose equivalent, and the DE value is a value indicating the degree of hydrolysis of starch, that is, the glycation rate of starch. DE value in the present invention is a value measured by the Willstatter-Schudel method. The DE value is measured as a specific value by the Willstatter-Schudel method. The properties of hydrolyzed starch (starch hydrolyzate), for example, the molecular weight of starch hydrolyzate and the arrangement of sugar molecules constituting starch hydrolyzate, are not constant for each molecule of starch hydrolyzate. It exists with a certain distribution or variation. Due to the distribution and variation of the properties of the starch hydrolyzate, or the difference in the cut section, etc., the starch hydrolyzate expresses different physical property characteristics (eg DE value) for each molecule. In this way, the starch hydrolyzate is a collection of molecules exhibiting different physical properties, but the measurement result (ie DE value) by the Willstatter-Schudel method is treated as a representative value indicating the degree of starch hydrolysis.

Preferably, the starch hydrolyzate may be selected from the group consisting of dextrins having a DE value of about 2 to about 5, indigestible dextrins having a DE value of about 10 to about 15, and mixtures thereof. As a dextrin having a DE value of about 2 to about 5, for example, Finedex #100 (Matsutani Chemical Industry Co., Ltd.) can be utilized. As the indigestible dextrin having a DE value of about 10 to about 15, for example, fine fiber (Matsutani Chemical Industry Co., Ltd.) can be utilized.

A perfume-containing sheet for a smoking article may include about 2 to about 15 parts by weight of water, about 25 to about 90 parts by weight of modified cellulose, and about 0.1 to about 60 parts by weight of perfume, based on 100 parts by weight total.

The slurry may further include a bulking agent, an aerosol former, or an emulsifier. As described above, the bulking material may be, for example, dextrin, the aerosol former may be, for example, at least one of glycerin and propylene glycol, and the emulsifier may be, for example, lecithin.

3A shows a perfume-containing sheet 300 for a smoking article before drying, and FIG. 3B shows a perfume-containing sheet 400 for a smoking article after drying.

Referring to FIGS. 3A and 3B , the perfume-containing sheet 300 for a smoking article before drying may have a thickness d1. After drying, the perfume-containing sheet 400 for smoking articles may have a thickness d2. The thickness d1 before drying may be equal to or greater than the thickness d2 after drying. As an example, before drying, the perfume-containing sheet 300 for a smoking article may have a thickness of about 0.2 to 2.0 mm, and after drying, the perfume-containing sheet 400 for a smoking article may have a thickness of about 0.01 to about 0.3 mm. The above-described difference in thickness may be due to a difference in moisture content due to drying.

4 is a cross-sectional view of a first portion 500 of a smoking article according to one example.

For example, FIG. 4 may represent a cross-section of a first portion of the smoking article of FIG. 1 .

Referring to FIG. 4 , the first portion 500 may include a tobacco material 511 and a flavoring-containing sheet 513 for a smoking article. Tobacco material 511 may be in the form of a tobacco sheet, such as, for example, a leaf cut filler. Tobacco material 511 may be a tobacco sheet impregnated with an aerosol generating material or the like.

When the first portion 500 is burned or heated, an aerosol may be generated from the tobacco material 511, and the volatilized spice components from the spice-containing sheet 513 may move together with the aerosol.

The following describes in detail the advantages of manufacturing perfume-containing sheets for smoking articles according to the present disclosure.

In general, when preparing a slurry using a polysaccharide material such as agar, gelatin, or gellan gum, the entire process may include (1) heating water to about 80° C. to about 100° C., (2) adding agar, gelatin, or gellan gum to dissolve, (3) cooling to about 60° C., and (4) adding a flavoring ingredient such as menthol.

In the step (3), the slurry needs to be continuously managed so as to be maintained at a temperature of about 60° C. in the storage tank, the transfer line, and the application nozzle.

In addition, since flavor components such as menthol do not dissolve in water, it is necessary to apply an emulsifier.

According to the present disclosure, a slurry of a perfume-containing sheet for a smoking article may include HPMC (or MC, CMC, EC) having a grade in a specific numerical range as a modified cellulose. It may also include slurries of perfume-containing sheets for smoking articles, such as distilled water, ethanol, dextrin, glycerin, and menthol. In this case, dextrin and glycerin may be dissolved in distilled water at room temperature, and HPMC (or MC, CMC, EC) and menthol may be dissolved in ethanol at room temperature.

In addition, according to the present disclosure, since the slurry of the spice-containing sheet for smoking articles contains a relatively low content of distilled water and a certain amount of alcohol, there is an advantage in that the drying time is relatively short.

When preparing the slurry of the spice-containing sheet for smoking articles according to the present disclosure, (1) dissolving menthol in ethanol, adding and dispersing HPMC (or MC, CMC, EC), (2) adding distilled water, and (3) adding a spice component. In this case, a process of separately heating the slurry is not required, and accordingly, there is no need to maintain the temperature in the storage tank, the transfer line, and the application nozzle. In addition, the slurry does not necessarily contain an emulsifier.

Table 1 below shows the content ratio of each component in the spice-containing sheet for smoking articles according to an embodiment. Ethanol was completely evaporated in the process of drying the slurry.

division HPMC
(or MC, CMC, EC) menthol moisture propylene glycol Sum Content (wt%) 52.6 29.8 7.0 10.5 100

The prepared perfume-containing sheet for smoking articles was excellent in at least one of viscosity characteristics, slurry formation characteristics, drying characteristics, sheet physical properties, and flavor retention.

A third aspect of the present disclosure relates to a combustible cigarette (600) comprising a first segment (610) comprising a tobacco material and a flavoring-containing sheet, and a second segment (620) comprising a filter element, the first segment (610) and the second segment (620) being sequentially arranged in the longitudinal direction of the combustion cigarette (600), the flavoring-containing sheet comprising a modified cellulose. A kite 600 may be provided.

Combustion cigarette 600 can be used when the first segment 610 is ignited by a user. When the first segment 610 is ignited, fragrance generated from the spice-containing sheet may flow to the second segment 620 together with cigarette smoke.

The above-described information about the smoking article and the spice-containing sheet for smoking articles may be equally applied to the combustion cigarette 600 according to the third aspect of the present disclosure.

Those skilled in the art related to the present embodiment will be able to understand that it may be implemented in a modified form within a range that does not deviate from the essential characteristics of the above description. Therefore, the disclosed methods are to be considered in an illustrative rather than a limiting sense. The scope of the invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope should be construed as being included in the invention.
