The fifth wrapper 235 and the sixth wrapper 236 may prevent the cigarette 2 from burning. For example, when the tobacco rod 210 is heated by the heater 130, there is a possibility that the cigarette 2 is burned. Specifically, when the temperature rises above the flash point of any one of the materials included in the tobacco rod 210, the cigarette 2 may be burned. Even in this case, since the fifth wrapper 235 and the sixth wrapper 236 include a non-combustible material, the phenomenon in which the cigarette 2 is burned can be prevented.

In addition, the fifth wrapper 235 may prevent the holder 1 from being contaminated by materials generated from the cigarette 2. By the puff of the user, liquid substances can be produced in the cigarette 2. For example, the aerosol produced in the cigarette 2 is cooled by the outside air, whereby liquid substances (eg moisture) can be produced. As the fifth wrapper 235 packs the tobacco rod 210 and / or the first filter segment 221, it is possible to prevent liquid substances produced in the cigarette 2 from leaking out of the cigarette 2. Can be. Therefore, the phenomenon in which the inside of the holder 1 is contaminated by the liquid substances produced in the cigarette 2 can be prevented.

The diameter of the cigarette 2 is within the range of 5mm to 9mm, the length may be about 48mm, but is not limited thereto. For example, the length of the tobacco rod 210 is about 12 mm, the length of the first filter segment 221 is about 10 mm, the length of the cooling structure 222 is about 14 mm, and the length of the second filter segment 223 is about 12 mm, but is not limited thereto.

The structure of the cigarette 2 shown in FIG. 2 is merely an example, and some configurations may be omitted. For example, the cigarette 2 may not include one or more of the first filter segment 221, the cooling structure 222, and the second filter segment 223.

Tobacco rod 210 includes an aerosol generating material. For example, the aerosol generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

In addition, tobacco rod 210 may contain other additive materials, such as flavoring agents, wetting agents, and / or organic acids. For example, the flavoring agent is licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, Vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee and the like. Wetting agents may also include glycerin or propylene glycol and the like.

As an example, the tobacco rod 210 may be filled with a reconstituent tobacco sheet.

As another example, the tobacco rod 210 may be filled with sheaths. Here, tobacco sheaths can be produced by slicing the leaflet sheet.

As another example, the tobacco rod 310 may be filled with a plurality of tobacco strands in which the leaflet sheet is trimmed. For example, the tobacco rod 310 may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly.

For example, the platelet sheet may be manufactured by the following procedure. First, tobacco raw materials are ground to produce aerosol generating materials (e.g., glycerin, propylene glycol, etc.), fragrance liquids, binders (e.g., guar gum, xanthan gum, Carboxymethyl cellulose (CMC), etc.), water After making the slurry mixed with the back, the platelet sheet is formed using the slurry. When making the slurry, natural pulp or cellulose may be added, and one or more binders may be mixed and used. On the other hand, tobacco strands may be produced by cutting or slicing the dried leaflet sheet.

The tobacco raw material may be tobacco leaf chips, tobacco stems and / or tobacco fines generated during tobacco processing. The leaflet sheet may also contain other additives such as wood cellulose fibers.

5% to 40% of the aerosol generating material may be added to the slurry, and 2% to 35% of the aerosol generating material may be left in the platelet sheet. Preferably, 5% to 30% of the aerosol generating material may remain in the leaflet sheet.

In addition, before the tobacco rod 210 is packaged by the first wrapper 231, a perfume liquid such as menthol or a moisturizer may be sprayed and added to the center of the tobacco rod 210.

The first filter segment 221 may be a cellulose acetate filter. For example, the first filter segment 221 may be a tube-shaped structure including a hollow therein. The length of the first filter segment 221 may be an appropriate length within the range of 4mm to 30mm, but is not limited thereto. Preferably, the length of the first filter segment 221 may be 10 mm, but is not limited thereto.

The diameter of the hollow included in the first filter segment 221 may be an appropriate diameter within the range of 2mm to 4.5mm, but is not limited thereto.

The hardness of the first filter segment 221 may be adjusted by adjusting the amount of plasticizer in the manufacture of the first filter segment 221.

In addition, the first filter segment 221 may be manufactured by inserting a structure such as a film or a tube of the same or a different material into the inside (eg, a hollow).

The first filter segment 221 may be manufactured using cellulose acetate. Accordingly, when the heater 130 is inserted, the internal material of the tobacco rod 210 may be prevented from being pushed back, and a cooling effect of the aerosol may be generated.

The cooling structure 222 cools the aerosol generated by the heater 130 heating the tobacco rod 210. Thus, the user can inhale the aerosol cooled to the appropriate temperature.

The length or diameter of the cooling structure 222 may be variously determined according to the shape of the cigarette 2. For example, the length of the cooling structure 222 may be appropriately employed within the range of 7mm to 20mm. Preferably, the length of the cooling structure 222 may be about 14 mm, but is not limited thereto.

The cooling structure 222 can be made by weaving polymer fibers. In this case, the perfume solution may be applied to the fibers made of the polymer. Alternatively, the cooling structure 222 may be manufactured by weaving together the fibers made of the polymer and the fibers coated with the perfume solution.

Alternatively, the cooling structure 222 may be formed by a crimped polymer sheet. The polymer is made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA) and aluminum foil Can be.

As the cooling structure 222 is formed by a woven polymer fiber or crimped polymer sheet, the cooling structure 222 may include singular or plurality of channels extending in the longitudinal direction. Here, the channel means a passage through which gas (eg, air or aerosol) passes.

For example, the cooling structure 222 made of crimped polymer sheet may be formed from a material having a thickness between about 5 μm and about 500 μm, for example between about 10 μm and about 250 μm. In addition, the total surface area of the cooling structure 222 may be between about 300 mm ² / mm and about 1000 mm ² / mm. In addition, the aerosol cooling element may be formed from a material having a specific surface area of between about 10 mm ² / mg and about 100 mm ² / mg.

Meanwhile, the cooling structure 222 may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited thereto. For example, the thread may be filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the cooling structure 222.

The second filter segment 223 may be a cellulose acetate filter. The length of the second filter segment 223 may be suitably employed within the range of 4 mm to 20 mm. For example, the length of the second filter segment 223 may be about 12 mm, but is not limited thereto.

In the process of manufacturing the second filter segment 223, the flavor may be produced by spraying the fragrance liquid on the second filter segment 223. Alternatively, a separate fiber coated with the fragrance liquid may be inserted into the second filter segment 223. The aerosol generated in the tobacco rod 210 is cooled as it passes through the cooling structure 222, and the cooled aerosol is delivered to the user through the second filter segment 223. Thus, when the flavor element is added to the second filter segment 223, the effect of enhancing the persistence of the flavor delivered to the user may be produced.

Generally, the flavor liquid can be prepared by adding flavor components to the solution. For example, the flavor solution may be prepared by adding a lactone-based flavor component to ethanol or propylene glycol (PG). However, the flavor solution prepared in this manner (adding the flavor component to the solution) may be diluted or lost as the flavor component is mixed into the solution. Accordingly, the aroma concentration that is substantially expressed may be limited.

Flavor compound contained in the fragrance liquid according to one embodiment may be prepared by binding the flavor component to the carrier. Specifically, the flavor compound may be prepared by binding a flavor component (flavor molecule) to a cavity included in the carrier.

Hereinafter, an example of preparing a flavor compound will be described with reference to FIGS. 3 to 5.

3 is a view for explaining an example of the flavor component and the carrier included in the flavor compound.

3 illustrates an example in which the flavor component 310 and the carrier 320 are combined and decomposed.

The flavor compound 330 in which the flavor component 310 and the carrier 320 are combined may be manufactured by a dropping inclusion method, a solution mixing method, a slurry inclusion method, or the like. In addition, mass production can also be carried out by spray drying, fluidized bed, or the like. For example, starch, cellulose, gum and the like may be used as the binder. In addition, additives such as maltodextrin may be applied in combination to enhance inclusion efficiency and retention.

For example, the flavor component 310 includes menthol, mint, such as peppermint and spearmint, chocolate, licorice, citrus and other fruit flavors, vanillin, ethyl vanillin, breath freshener flavor, spices like cinnamon, bergamot It may be one or more flavoring agents, including but not limited to oils, geranium oils, lemon oils, ginger oils and tobacco flavors. Preferably, the flavor component 310 may be, but is not limited to, menthol and at least one mint flavor.

The carrier 320 includes an interior cavity that can accommodate the flavor component 310. For example, the carrier 320 may be cyclodextrin, but is not limited thereto. In addition, the carrier 320 may be Hydroxy-propyl-beta-cyclodextrin (HPBCD) having improved solubility than cyclodextrin, but is not limited thereto.

Cyclodextrins are functional oligosaccharides having a cyclic structure which are prepared by enzymatic reaction using starch as a raw material. Cyclodextrins have internal spaces that can form inclusion compounds with other materials. Thus, by utilizing these properties of the cyclodextrin, the flavor component 310 can be supported in the internal space to form a complex. Since the flavor component 310 is mostly hydrophobic, it can be bonded by hydrogen bonding to a functional group inside the cyclodextrin. Hereinafter, the type of cyclodextrin will be described with reference to FIG. 4.

4A-4C show examples of cyclodextrins.

The structure of alpha-cyclodextrin in FIG. 4A, beta-cyclodextrin in FIG. 4B, and gamma-cyclodextrin in FIG. 4C is shown.

Cyclodextrins exist in various forms such as alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, etc., depending on the molecular weight. Therefore, it can be selectively used according to the use. For example, gamma-cyclodextrin has the highest water solubility (solubility) compared to alpha-cyclodextrin and beta-cyclodextrin. When cyclodextrin is used as the carrier 320, it is effective in stabilizing, solubilizing, improving light safety of the flavor component 310, and the like.

Referring back to FIG. 3, the flavor compound 330 may be decomposed in a high temperature environment. For example, the flavor compound 330 may be decomposed into the flavor component 310 and the carrier 320 at a high temperature of 300 ° C. or higher. However, the temperature at which the flavor compound 330 is decomposed is not limited to the above-mentioned temperature.

For example, when the temperature of the flavor compound 330 increases due to electrical heating or combustion, the matrix of the carrier 320 may be decomposed to express the flavor component 310 bonded to the carrier 320.

5 shows the thermal stability of cyclodextrins.

Cyclodextrin, which is one example of the carrier 320, is stable to heat and starts to decompose at a high temperature of about 300 ° C or higher. Kinds of cyclodextrins, alpha-cyclodextrin, beta-cyclodextrin, and gamma-cyclodextrin, show the same thermal stability near about 300 ° C.

Referring back to FIG. 2, flavor may be generated by applying a flavor liquid (ie, a solution comprising the flavor compound 330) to at least one of the first wrapper 231 to the sixth wrapper 236. As an example, the fragrance liquid may be sprayed (coated) on the surface of the wrapper. For example, when the viscosity and composition of the fragrance liquid to be applied are adjusted and applied in the longitudinal direction of the cigarette (2), a richer flavor component can be expressed. However, a proper amount of fragrance liquid may be applied so that the shrinkage of the wrapper does not occur.

As another example, the perfume solution may be mixed with the adhesive, and the adhesive with the perfume solution mixed may be applied onto the wrapper. For example, the content of the flavor compound in the perfume solution may be determined so as not to affect the adhesion of the adhesive, and may be sufficiently dispersed so that the nozzle into which the perfume solution is injected is not blocked.

Those skilled in the art will appreciate that the present invention may be embodied in a modified form without departing from the essential characteristics of the above-described substrate. Therefore, the disclosed methods should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.
