Description

TECHNICAL FIELD

One or more embodiments of the present disclosure relate to a fragrance-containing sheet including LM-pectin for smoking articles, and a smoking article including the same.

BACKGROUND ART

In order to generate a specific fragrance from a smoking article, a method of adding a fragrance component in a solution state to a cigarette has been employed. This method has an advantage in that the fragrance component may be easily applied to the cigarette by spraying a fragrance solution. However, if an amount of fragrance is increased to release more fragrance during smoking, an amount of solvent also has to increase, and thus stains tend to occur on the cigarette paper. In addition, there is a disadvantage in that the fragrance is weakened as smoking progresses.

FIG. 1 is a schematic diagram illustrating a configuration of a smoking article 100, according to an embodiment.

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

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

The first portion 110 may include the tobacco element. The tobacco element may be a specific type of tobacco material. For example, the tobacco element may have the form of tobacco cut fillers, tobacco particles, tobacco sheets, tobacco beads, tobacco granules, or tobacco extracts. In addition, the tobacco material may include, for example, one or more of tobacco leaves, tobacco side veins, puffed tobacco, cut fillers, leaf tobacco cut fillers, and reconstituted tobacco.

The second portion 120 may include the filter element. The filter element may be a cellulose acetate filter. There are no limitations on a shape of the filter element. For example, the filter element may be a cylindrical rod or a tubular rod containing a hollow therein. Alternatively, the filter element may be a recessed rod.

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

In addition, the second portion 120 may include at least one capsule 130. Here, the capsule 130 may serve to generate flavor, or may serve to generate an aerosol. For example, the capsule 130 may have a structure in which a liquid containing fragrance is wrapped with a film. The capsule 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 greater detail with reference to FIG. 1.

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

The cooling element 121 may cool an airflow passing through the first portion 110 from the outside of the smoking article 100. The cooling element 121 may be formed of a paper material, and may be a cylindrical paper tube including a hollow therein. 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. 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-described example, and embodiments of the present disclosure may include any material that performs a function of cooling the airflow. Alternatively, the cooling element 121 may be a tube filter or a paper tube including a hollow therein.

In addition, although not illustrated in FIG. 1, the smoking article 100 may further include a plug (not shown). The plug may be arranged at a distal end of the smoking article 100. For example, the plug may be arranged at the distal end of the smoking article 100 adjacent to the first portion 110. The plug may serve to properly regulate an overall length of the smoking article 100. In addition, when the smoking article 100 is inserted into an aerosol generating device (not shown), the plug may serve to regulate the first portion 110 to be arranged at an appropriate position within the aerosol generating device.

The smoking article 100 may include at least one wrapper 140. For example, the smoking article 100 may include a first wrapper surrounding the first portion 110, and a second wrapper surrounding the second portion 120. The smoking article 100 may also include a third wrapper surrounding the first portion 110 and the second portion 120 completely. The smoking article 100 may also include a fourth wrapper surrounding the second portion 120. The fourth wrapper may, generally, serve as a tip paper.

At least one of the first to fourth wrappers may be a biodegradable wrapper. When a biodegradable wrapper is used, the smoking article 100 may be rapidly decomposed by microorganisms, and thus environmental pollution may be reduced.

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

Referring to FIG. 2, the smoking article 200 may include a first portion 210 and a second portion 220. The second portion 220 may include a filter element. Descriptions given above with respect to the second portion 120 of FIG. 1 may be equally applied to the second portion 220 of FIG. 2.

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

The aerosol generating substrate 211 may include, for example, crimped paper impregnated with an aerosol generating material. The aerosol generating material (or aerosol former) may include, for example, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

The nicotine generating substrate 213 may include, for example, tobacco cut fillers, tobacco particles, tobacco sheets, tobacco beads, or tobacco granules. As another example, the nicotine generating substrate 213 may include crimped paper impregnated with tobacco extracts. When the nicotine generating substrate 213 is heated, nicotine may be generated from the nicotine generating substrate 213 and be transferred to the second portion 220.

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

The descriptions given above with respect to the cooling element 121 and the filter element 123 of FIG. 1 may be equally applied to the cooling element 221 and the filer element 223 of FIG. 2. Therefore, redundant descriptions thereof will be omitted.

The fragrance-containing sheet for smoking articles according to one or more embodiments of the present disclosure may be included within the first portion 110 and 210, or the second portion 120 and 220 of the smoking article 100 and 200 shown in FIGS. 1 and 2.

In order to manufacture the fragrance-containing sheet for smoking articles according to one or more embodiments of the present disclosure, a slurry (or crude liquid) including distilled water, thickened polysaccharides, LM-pectin (low methyl pectin), and fragrance may be used. The slurry may further contain a bulking agent, an aerosol former, or an emulsifier.

The distilled water may be a factor that determines the viscosity of the slurry.

The thickened polysaccharide may be a polysaccharide material that serves to increase the viscosity of the slurry. The thickened polysaccharide may include, for example, at least one of agar, gellan gum, tamarind gum, konjac glucomannan, sylium seed gum, locust bean gum, guar gum, xanthan gum, tara gum, starch, and cassia gum.

LM-pectin is a low ester pectin or low methoxyl pectin with relatively little esterification, and specifically refers to a pectin containing less than about 50% of carboxyl groups in a molecular structure. Unlike carrageenan, LM-pectin does not gel when cooled at room temperature. For this reason, the slurry may have a relatively low viscosity (about 600 cp to about 800 cp). In addition, the slurry may be manufactured without necessarily including an emulsifier.

LM-pectin may contain less than about 50%, less than about 40%, less than about 30%, less than about 20%, or less than about 10% of carboxyl groups within the molecular structure. As content of the carboxyl groups in the molecular structure of LM-pectin decreases, viscosity of the slurry containing LM-pectin may decrease.

The bulking agent serves to increase a total mass (i.e., dry matter mass) of constituents other than the distilled water in the slurry, thereby increasing a volume of the fragrance-containing sheet to be produced. The bulking agent only serves to increase the volume of the fragrance-containing sheet and does not affect an original function of the fragrance-containing sheet. More specifically, the bulking agent does not substantially increase the viscosity of the slurry, and does not adversely affect a fragrance retention function of the fragrance-containing sheet.

The bulking agent may be starch, modified starch, or starch hydrolyzate. The modified starch refers to acetic acid starch, oxidized starch, hydroxypropyl phosphate distarch, hydroxypropyl phosphate, phosphate distarch, monolithic phosphate, phosphate diphosphate, and the like. The starch hydrolyzate refers to a substance obtained by a process of hydrolyzing starch. The starch hydrolyzate 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 bulking agent may be, for example, dextrin, and more specifically, cyclodextrin.

The starch hydrolyzate may, generally, be a starch hydrolyzate having a dextrose equivalent (DE) value within a range of about 2 to about 40, and preferably a starch hydrolyzate having a DE value within a range of about 2 to about 20. As a starch hydrolyzate having a DE value within a range of about 2 to about 20, for example, Finedex #100 (Matsutani Chemical Industries Co., Ltd.), Fine Fiber (Matsutani Chemical Industries Co., Ltd.), or TK-16 (Matsutani Chemical Industry Co., Ltd.) may be used.

The DE value represents a degree of hydrolysis of starch, that is, a saccharification rate of starch. In the present disclosure, the DE value may be measured by a Willstatter-Schudel method. The DE value is measured, as a specific value, by the Willstatter-Schudel method. Properties of the hydrolyzed starch (i.e., starch hydrolyzate), such as a molecular weight of the starch hydrolyzate or an arrangement of sugar molecules constituting the starch hydrolyzate, are not identical among the molecules of the starch hydrolyzate, and may differ according to a certain distribution or variations. The starch hydrolyzate exhibits different physical properties (for example, DE value) for each molecule due to the distribution and variations of the properties of the starch hydrolyzate, a difference in the cut section, or the like. As described above, the starch hydrolyzate is a set of molecules representing different physical properties, but a result (i.e., DE value) measured by the Willstatter-Schudel method is regarded as a representative value indicating a degree of hydrolysis of starch.

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

The fragrance may include, for example, menthol, leaf tobacco extracts, natural botanical fragrance (e.g., cinnamon, sage, herbs, chamomile, reeds, 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, isomer sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (e.g., menthone, ionone, damasenone, ethyl maltol, etc.), alcohol classes (e.g., geraniol, linalol, anetol, eugenol, etc.), aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g., γ-undecalactone), γ-nonalactone, etc.), animal flavors (e.g., musk, amber lys, civet, castrium, etc.), hydrocarbons (e.g., limonene, pinene, etc.).

The fragrance may be used in a solid state, or may be dissolved or dispersed in an appropriate solvent such as propylene glycol, ethyl alcohol, benzyl alcohol, or triethyl citrate. In addition, fragrances that are easily dispersed in a solvent by the addition of an emulsifier, for example, hydrophobic fragrances, oil soluble fragrances, etc. may be used. These fragrances 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 fragrances used in the smoking article.

The slurry may further contain an aerosol former or an emulsifier. The aerosol former may include, for example, at least one of glycerin and propylene glycol, and the emulsifier may be, for example, lecithin.

According to an embodiment, the fragrance-containing sheet for smoking articles may include, based on a total of 100 parts by weight, about 2 to about 15 parts by weight of moisture, about 1 to about 60 parts by weight of thickened polysaccharide, about 1 to about 60 parts by weight of LM-pectin, and about 0.1 to about 60 parts by weight of fragrance.

The fragrance-containing sheet for smoking articles may also include, based on a total of 100 parts by weight, about 0.1 to about 15 parts by weight of the aerosol former.

FIG. 3A is a diagram illustrating a fragrance-containing sheet 300 for smoking articles before being dried, and FIG. 3B is a diagram illustrating a fragrance-containing sheet 400 for smoking articles after being dried.

Referring to FIGS. 3A and 3B, the fragrance-containing sheet 300 before being dried may have a thickness d1. The fragrance-containing sheet 400 after being dried may have a thickness d2. The thickness dl of the fragrance-containing sheet 300 before being dried may be greater than the thickness d2 of the fragrance-containing sheet 400 after being dried. As an example, the fragrance-containing sheet 300 before being dried may have a thickness of about 0.2 mm to about 2.0 mm, and the fragrance-containing sheet 400 after being dried may have a thickness of about 0.01 mm to about 0.3 mm. The above-described difference in thickness may be derived from a difference in moisture content due to drying.

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

For example, FIG. 4 may be a cross-sectional view of the 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 fragrance-containing sheet 513. The tobacco material 511 may be, for example, in the form of a tobacco sheet such as leaf tobacco cut fillers. Alternatively, the tobacco material 511 may be a tobacco sheet impregnated with an aerosol generating material or the like.

When the first portion 500 is combusted or heated, an aerosol may be generated from the tobacco material 511, and a fragrance component volatilized from the fragrance-containing sheet 513 may move along with the aerosol.

Hereinafter, embodiments and examples of manufacturing a fragrance-containing sheet for smoking articles will be described in detail.

EXAMPLE 1

1. Preparation of Slurry

In Example 1, 2.5 g of agar was added to 72.5 g of water and stirred at 95° C. Thereafter, 2.0 g of pectin was added and stirred, and 3 g of glycerin was added and cooled to 50° C. Then, 15 g of menthol was added and stirred to remove air bubbles. A finished slurry was maintained at a temperature of about 50° C.

In Comparative Examples 1-5, the slurry was prepared by changing a weight ratio of each component as shown in Table 1 below.

2. Manufacturing of a Fragrance-containing Sheet for Smoking Articles

The above-described slurry was dried to make a fragrance-containing sheet having a thickness of about 0.01 mm. A moisture content of the dried fragrance-containing sheet for smoking articles was within a range of about 2 to about 15 parts by weight. More specifically, moisture content was about 8 parts by weight.

As shown in Table 2, Example 1 was evaluated to be superior to

Comparative Example 1-5 in at least one of viscosity properties, slurry formation properties, drying properties, sheet physical properties, and fragrance retention properties. In addition, Example 1 was excellent in terms of an ability to prepare slurry and an ability to prepare a sheet, even without including an emulsifier. However, the embodiments may use the emulsifier.

Comparative Example 1 had good slurry formation, but the drying time was relatively long. After the drying process is completed, menthol content was relatively low and a retention time was relatively short. In Comparative Example 2, slurry stability was poor, so phase separation occurred over time and it was difficult to prepare a uniform sheet. In Comparative Example 3, slurry viscosity was high, making it difficult to manufacture a sheet. Comparative Example 4 had poor sheet manufacturing ability and the manufactured sheet had poor quality. Comparative Example 5 had a high viscosity of the slurry, making it difficult to manufacture a sheet.

FIG. 5 is a schematic diagram illustrating a configuration of a combustion-type cigarette 600.

According to an embodiment, the combustion-type cigarette 600 includes: a first segment 610 including a tobacco material and a fragrance-containing sheet; and a second segment 620 including a filter element. The first segment 610 and the second segment 620 are arranged along a longitudinal direction of the combustion-type cigarette 600, and the fragrance-containing sheet includes LM-pectin.

The first segment 610 may be ignited by a user. As the first segment 610 is ignited, fragrance generated from the fragrance-containing sheet may flow into the second segment 620 along with cigarette smoke.

That is, the descriptions given above with respect to the fragrance-containing sheet for smoking articles may be equally applied to the combustion-type cigarette 600.
