Fig. 1 is a schematic diagram showing a configuration of a smoking article 100 according to an embodiment.

The smoking article 100 may include a first element 110 comprising a tobacco element and a second element 120 comprising a filter element.

Referring to figure 1, the first portion 110 and the second portion 120 may be arranged in series along the longitudinal direction of the smoking article 100. Here, the longitudinal direction of the smoking article 100 may be the direction in which the length of the smoking article 100 extends. For example, the longitudinal direction of the smoking article 100 may be the direction in which the first and

second portions

110, 120 are arranged.

The first portion 110 may include a tobacco element. The tobacco element may be a particular type of tobacco material. For example, the tobacco element can be in the form of tobacco cut filler, tobacco particles, tobacco sheets, tobacco beads, tobacco particles, or tobacco extracts. Additionally, the tobacco material can include, for example, one or more of tobacco lamina, tobacco side vein, expanded tobacco, cut filler, tobacco lamina cut filler, and reconstituted tobacco.

The second portion 120 may comprise a segment of a single filter element. The filter element may be a cellulose acetate filter. There is no limitation on the shape of the filter element. For example, the filter element may be a cylindrical rod or a tubular rod including a hollow portion therein. Alternatively, the filter element may be a recessed rod.

The second portion 120 can be manufactured to generate a scent. By way of example, the scented liquid may be sprayed onto the second portion 120, or individual fibers coated with the scented liquid may be inserted into the second portion 120.

Additionally, the second portion 120 may include at least one bladder 130. Here, the bladder 130 may be used to generate a fragrance, or may be used to generate an aerosol. For example, bladder 130 may have a structure that encapsulates a fragrance-containing liquid with a film. The bladder 130 may have a spherical or cylindrical shape, but is not limited thereto.

The second portion 120 may also include a plurality of segments. The present embodiment will be described in more detail with reference to fig. 1.

The second portion 120 may include a filter element 123 and may also include a cooling element 121.

The cooling element 121 may cool the airflow from the exterior of the smoking article 100 through the first portion 110. The cooling element 121 may be formed of a paper material, and may be a cylindrical paper tube including a hollow portion. 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) fiber, but is not limited thereto. In addition, the cooling element 121 may be made of a cellulose acetate filter having a plurality of holes. However, the cooling element 121 is not necessarily limited to the above example, and embodiments of the present disclosure may include any material that performs a cooling function on the airflow. Alternatively, the cooling element 121 may be a tubular filter or paper tube comprising a hollow portion.

Additionally, although not shown in figure 1, the smoking article 100 may also include a plug (not shown). The plug may be arranged at the distal end of the smoking article 100. For example, the plug may be arranged at a distal end of the smoking article 100 adjacent to the first portion 110.

second portions

110, 120. The smoking article 100 may further comprise a fourth wrapper around the second portion 120. The fourth package may be used as a tipping paper in general.

At least one of the first package to the fourth package may be a biodegradable package. When using biodegradable packages, the smoking article 100 may be rapidly decomposed by microorganisms, and thus environmental pollution may be reduced.

Figure 2 is a schematic diagram illustrating a smoking article 200 according to another embodiment.

Referring to fig. 2, the smoking article 200 may comprise a first portion 210 and a second portion 220. The second portion 220 may include a filter element. The description given above with respect to the second portion 120 of fig. 1 is equally applicable to the second portion 220 of fig. 2.

Referring to fig. 2, the first portion 210 may be divided into two partitions. The first portion 210 may comprise an aerosol-generating substrate 211 and a nicotine-generating substrate 213.

The aerosol-generating substrate 211 may comprise, for example, a rolled paper impregnated with an aerosol-generating substance.

The second portion 220 may include a plurality of segments. For example, the second portion 220 may include a filter element 223, and may also include a cooling element 221.

The description given above with respect to the cooling element 121 and the filter element 123 of fig. 1 is equally applicable to the cooling element 221 and the filter element 223 of fig. 2. Therefore, redundant description of the cooling element 221 and the filter element 223 will be omitted.

A flavour-containing sheet material for a smoking article according to one or more embodiments of the present disclosure may be included within the first or

second part

110, 120 of the smoking article 100 shown in figure 1 and the first or

second part

210, 220 of the smoking article 200 shown in figure 2.

To prepare a flavor-containing sheet for a smoking article according to one or more embodiments of the present disclosure, a slurry (or crude liquid) comprising distilled water, ethanol, modified cellulose, and a flavor may be used. The slurry may further include at least one of a filler, an aerosol former, and an emulsifier.

The slurry may include about 1 wt% to about 80 wt% ethanol. Therefore, the modified cellulose can be dissolved better.

More specifically, distilled water and ethanol may be mixed in the slurry in a weight ratio of about 1:1 to about 10: 1. Preferably, the distilled water and ethanol may be mixed in a weight ratio of about 2.33: 1. Therefore, the modified cellulose can be dissolved better.

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

Ethanol may be used as the solvent. The ethanol may be, for example, anhydrous ethanol. When anhydrous ethanol is included in the slurry, modified cellulose such as HPMC, Methylcellulose (MC), carboxymethylcellulose (CMC), or Ethylcellulose (EC) and flavor components such as L-menthol are well soluble in the slurry at room temperature.

The modified cellulose may be cellulose in which a specific functional group is substituted in the molecular structure. The modified cellulose may be, for example, Hydroxypropylmethylcellulose (HPMC), Methylcellulose (MC), carboxymethylcellulose (CMC), or Ethylcellulose (EC). Hydroxypropyl methylcellulose can have a grade (grade) in the range of about 4 to about 40000 depending on the degree of substitution by hydroxypropyl and methyl groups (or methoxy groups). The viscosity of hydroxypropylmethylcellulose may be determined according to grade.

The modified cellulose may be, for example, AN6, AN15, AN50, BN10, BN50, MC15 or MC50, the product name of Lotte Fine Chemicals.

In experiments using MC15 or MC50 (cellulose with methyl group substitution) as modified cellulose, the viscosity characteristics, slurry formation characteristics, drying characteristics, sheet physical properties and flavor retention characteristics of the fragrance-containing sheet were confirmed to be excellent. In this case, the flavor-containing sheet material for a smoking article may have a viscosity in the range of about 100cp to about 10000cp when the slurry is prepared.

The flavors may include, for example, menthol, tobacco leaf extract, natural plant flavors (e.g., cinnamon, sage, herbaceous plant, chamomile, reed, persimmon tea, clove, lavender, cardamom, clove, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, mint, cinnamon, coffee, celery, gooseberry, sandalwood, cocoa, ylang, anise, licorice, saint john's bread, plum extract, peach extract, etc.), sugars (e.g., glucose, fructose, isomerose, caramel, etc.), cocoa (powder, extract, etc.), esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (e.g., menthone, irisone, daminone, ethyl maltol, etc.), (e.g., menthol, clove, nutmeg, orange, cinnamon, clove, lavender, clove, olive, green, olive, Alcohols (e.g., geraniol, linalool, anethole, eugenol, etc.), aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g., γ -undecalactone, γ -nonalactone, etc.), animal essences (e.g., musk, lysine amber, civet, castor, etc.), hydrocarbons (e.g., limonene, pinene, etc.).

The perfume may be used in a solid state or may be dissolved or dispersed in a suitable solvent such as propylene glycol, ethanol, benzyl alcohol or triethyl citrate. In addition, perfumes which are easily dispersed in a solvent by adding an emulsifier, for example, hydrophobic perfumes, oil-soluble perfumes, and the like can be used. These perfumes may be used alone or as a mixture. However, embodiments of the present disclosure are not necessarily limited thereto, and embodiments of the present disclosure may include any flavorant for use in a smoking article.

The filler serves to increase the total mass of ingredients other than water (i.e. dry matter mass) in the raw stock slurry, thereby increasing the volume of the perfume-containing sheet to be prepared. The filler serves only to increase the volume of the perfume-containing sheet without affecting the initial function of the perfume-containing sheet. More specifically, the filler does not substantially increase the viscosity of the raw material slurry and does not adversely affect the flavor-retaining function of the fragrance-containing sheet.

The bulking agent may be starch or a starch hydrolysate. Starch hydrolysate refers to the material obtained by subjecting starch to a hydrolysis process. The starch hydrolysate is, for example, a substance obtained by directly hydrolyzing starch (i.e., dextrin) or a substance obtained by hydrolyzing starch after heat treatment (i.e., indigestible dextrin). The filler may be, for example, dextrin, and more specifically, the filler may be cyclodextrin.

The starch hydrolysate may typically be a starch hydrolysate having a Dextrose Equivalent (DE) value in the range of about 2 to about 40, and preferably a starch hydrolysate having a DE value in the range of about 2 to about 20. As the starch hydrolysate having a DE value in the range of about 2 to about 20, for example, Finadex #100(Matsutani Chemical Industries Co., Ltd.), Fine Fiber (Matsutani Chemical Industries Co., Ltd.) or TK-16(Matsutani Chemical Industries Co., Ltd.) may be used.

The DE value may represent the degree of hydrolysis of the starch, i.e. the saccharification rate of the starch. DE values can be measured by the Willstatter-Schudel method. The DE value is measured as a specific value by the Willstatter-Schudel method. The properties of the hydrolyzed starch (i.e., the starch hydrolysate), such as the molecular weight of the starch hydrolysate or the arrangement of the sugar molecules making up the starch hydrolysate, are not identical among the molecules of the starch hydrolysate and may differ according to a particular distribution or variation. The starch hydrolysate exhibits physical properties (e.g., DE value) different for each molecule due to distribution and modification of the properties of the starch hydrolysate, difference in cut section, and the like. As described above, starch hydrolysate is a group of molecules representing different physical properties, but the result measured by the willstat-Schudel method (i.e., DE value) is considered as a representative value indicating the degree of starch hydrolysis.

Preferably, the starch hydrolysate may be selected from 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 dextrin having a DE value of about 2 to about 5, for example, Finedex #100(Masutani Chemical Industries co., Ltd.) can be used. For example, fine fibers (Matsutani Chemical co., Ltd.) may be used as the indigestible dextrin having a DE value of about 10 to about 15.

The fragrance-containing sheet material may comprise about 2 to about 15 parts by weight of moisture, about 25 to about 90 parts by weight of modified cellulose, and about 0.1 to about 60 parts by weight of fragrance, based on 100 parts by weight of the total amount.

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

Fig. 3A is a view showing the fragrance-containing sheet material 300 before being dried, and fig. 3B is a view showing the fragrance-containing sheet material 400 after being dried.

Referring to fig. 3A and 3B, the fragrance-containing sheet 300 before being dried can have a thickness d 1. The sheet material 400 containing fragrance after being dried may have a thickness d 2. The thickness d1 of the fragrance-containing sheet 300 before being dried can be greater than the thickness d2 of the fragrance-containing sheet 400 after being dried. By way of example, the fragrance-containing sheet 300 before being dried may have a thickness of about 0.2mm to about 2.0mm, and the fragrance-containing sheet 400 after being dried may have a thickness of about 0.01mm to about 0.3 mm. The difference in thickness may result from a difference in moisture content caused by drying.

Figure 4 is a diagram illustrating a cross-section of a first portion 500 of a smoking article according to an embodiment.

For example, figure 4 may be a cross-sectional view of a first portion of the smoking article of figure 1.

Referring to fig. 4, the first portion 500 may include a tobacco material 511 and a flavor-containing sheet material 513. The tobacco material 511 may be in the form of, for example, a tobacco sheet, such as cut filler of tobacco leaves. Alternatively, the tobacco material 511 may be a tobacco sheet impregnated with an aerosol generating substance or the like.

When the first portion 500 is combusted or heated, an aerosol can be generated from the tobacco material 511, and flavor components volatilized from the flavor-containing sheet material 513 can move with the aerosol.

Hereinafter, advantages in the manufacture of a tablet-containing material for a smoking article will be described in detail.

Generally, when a polysaccharide material such as agar, gel, gellan gum, etc. is used to prepare the slurry, the manufacturing process may include the following working steps: (1) heating water to about 80 ℃ to about 100 ℃; (2) adding and dissolving agar, gelatin or gellan gum; (3) cooling to about 60 ℃; and (4) adding a flavor component such as menthol.

In the above work step (3), it is necessary to maintain the slurry in the storage tank, the transfer line, the application nozzle, and the like at about 6 ℃.

In addition, because flavor components such as menthol are insoluble in water, emulsifiers are required.

According to one or more embodiments of the present disclosure, a slurry of flavor-containing sheet material for smoking articles may include a modified cellulose (e.g., HPMC, MC, CMC, or EC) having a grade within a particular range of values. Additionally, the tablet-containing slurry for smoking articles may comprise, for example, distilled water, anhydrous ethanol, dextrin, glycerol and menthol. In this case, dextrin and glycerin can be dissolved in distilled water at room temperature, and menthol and modified cellulose (e.g., HPMC, MC, CMC, or EC) can be dissolved in absolute ethanol at room temperature.

A flavor-sheet-containing slurry for a smoking article according to one or more embodiments of the present disclosure includes a relatively small amount of distilled water and at least a specific amount of ethanol. The advantage is therefore that the drying time is relatively short.

In preparing a slurry of flavour-containing sheet material for a smoking article according to one or more embodiments of the present disclosure, the manufacturing process may comprise the following work steps: (1) dissolving menthol in absolute ethanol and adding and diffusing a modified cellulose (e.g. HPMC, MC, CMC or EC); (2) adding distilled water; and (3) adding a fragrance component. Therefore, a process of separately heating the slurry is not required, and thus the temperature in the storage tank, the transfer line, the application nozzle, and the like does not need to be maintained. In addition, the slurry need not contain an emulsifier.

Table 1 below shows content ratios of each component of the flavor-containing sheet for smoking articles according to the embodiments. The absolute ethanol was totally evaporated while the slurry was being dried.

[ Table 1]

The resulting flavor-containing sheet material for smoking articles is excellent in at least one of viscosity characteristics, slurry formation characteristics, drying characteristics, sheet physical properties, and flavor retention characteristics. Figure 5 is a schematic diagram illustrating the configuration of a combustion cigarette 600. According to an embodiment, the combustion cigarette 600 comprises: a first segment 610 comprising a tobacco material and a flavor-containing sheet; and a second section 620 comprising a filter element. The first section 610 and the second section 620 are arranged in series along the longitudinal direction of the combustion cigarette 600 and the flavor-containing sheet material comprises modified cellulose.

The first segment 610 may be ignited by a user. When the first segment 610 is lit, the flavor generated from the flavor-containing sheet material can flow with the cigarette smoke into the second segment 620.

The description given above with respect to the flavor-containing sheet material for a smoking article and the smoking article can be equally applicable to the combustion cigarette 600 according to another aspect of the present disclosure.

It will be understood by those of ordinary skill in the art having regard to this embodiment that various changes in form and details may be made therein without departing from the scope of the features described above. The disclosed methods are to be considered in a descriptive sense only and not for purposes of limitation. Therefore, the scope of the present disclosure should be defined by the appended claims, and all differences within the scope equivalent to the scope described in the claims should be construed as being included in the protection scope defined in the claims.
