Description

cigarette

The present disclosure provides a cigarette comprising a tobacco rod and a filter rod.

In recent years there is a growing demand for alternative ways to overcome the shortcomings of common cigarettes. For example, there is an increasing demand for how aerosols are produced as the aerosol generating material in the cigarette is heated, rather than burning the cigarette to produce aerosols.

Cigarettes include filters, which serve to filter or cool specific components contained in the aerosol. If the filtering performance of the filter is too high, the aerosol transition amount is reduced, and if the filtering performance is too low, there is a problem that a specific component contained in the aerosol is not filtered.

Accordingly, research on a filter having appropriate performance is underway by changing the components constituting the filter or the structure of the filter.

To provide a cigarette comprising a mouthpiece composed of a central portion formed of an incompressible polymer material and an outer portion formed of a compressed polymer material surrounding the central portion. The technical problem to be achieved by the present embodiment is not limited to the technical problems as described above, and further technical problems can be inferred from the following embodiments.

Disclosed is a cigarette comprising a tobacco rod, a support segment located at a downstream end of the tobacco rod, a cooling segment located at a downstream end of the support segment, and a mouthpiece located at a downstream end of the cooling segment.

The cigarette according to the present embodiment discloses a mouthpiece including a central portion formed of an incompressible polymer material and an outer portion formed of a compressed polymer material surrounding the central portion.

According to the present invention, it is possible to increase the performance of aerosols by forming the central portion of the mouthpiece with a low packing density polymer material. In addition, the mouthpiece is formed of a compressed polymer material surrounding the central part and the central part formed of the non-compressed polymer material, so that when the user bites and smokes the mouthpiece of the cigarette, the sensitivity to the mouthpiece can be improved.

The outside air may be introduced through at least one air passage formed in the holder 1. Alternatively, the outside air may be introduced through at least one hole formed in the surface of the cigarette 2.

2 is a configuration diagram showing an example of a cigarette.

Referring to FIG. 2, the cigarette 2 includes a tobacco rod 210, a first filter segment 221, a cooling structure 222 and a second filter segment 223. The first portion described above with reference to FIG. 1 includes a tobacco rod 210, and the second portion includes a first filter segment 221, a cooling structure 222, and a second filter segment 223.

Referring to FIG. 2, the cigarette 2 may be wrapped by the

wrappers

231, 232, 233, 234, 235, and 236. For example, the tobacco rod 210 is wrapped by the first wrapper 231, and the first filter segment 221 is wrapped by the second wrapper 232. In addition, the cooling structure 222 is wrapped by a third wrapper 233, and the second filter segment 223 is packed by a fourth wrapper 234.

The fifth wrapper 235 may be surrounded by the first wrapper 231, the second wrapper 232, and the third wrapper 233. In other words, the tobacco rod 210, the first filter segment 221 and the cooling structure 222 of the cigarette 2 may be further packed by the fifth wrapper 235. In addition, the sixth wrapper 236 may be surrounded by at least a portion of the fifth wrapper 235 and an outer portion of the fourth wrapper 234. In other words, at least a portion of the cooling structure 222 of the cigarette 2 and the second filter segment 223 may be further packed by a sixth wrapper 236.

The first wrapper 231, the second wrapper 232, the fifth wrapper 235, and the sixth wrapper 236 may be manufactured by a general winding paper. For example, the first wrapper 231, the second wrapper 232, the fifth wrapper 235, and the sixth wrapper 236 may be porous wrappers or porous wrappers. For example, the thickness of the first wrapper 231 may be about 61 μm and the porosity may be about 15 CU, and the thickness of the second wrapper 232 may be about 63 μm and the porosity may be about 15 CU, but is not limited thereto. . In addition, the fifth wrapper 235 may have a thickness of about 66 μm and a porosity of about 10 CU, and the sixth wrapper 236 may have a thickness of 66 μm and a porosity of about 17 CU, but is not limited thereto.

In addition, an aluminum foil may be further included on the inner surfaces of the first wrapper 231 and / or the second wrapper 232.

The third wrapper 233 and the fourth wrapper 234 may be manufactured by hard winding. For example, the thickness of the third wrapper 233 may be about 158 μm and the porosity may be about 33 CU, and the thickness of the fourth wrapper 234 may be about 155 μm and the porosity may be about 46 CU, but is not limited thereto. .

The fifth wrapper 235 and the sixth wrapper 236 may be embedded with a predetermined material. Here, silicon may be used as an example of the predetermined material, but is not limited thereto. For example, silicon has characteristics such as heat resistance with little change with temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency for water, or electrical insulation. However, even if not silicon, any material having the above-described characteristics may be applied (or coated) to the fifth wrapper 235 and the sixth wrapper 236 without limitation.

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 consisting of crimped polymer sheet may be formed from a material having a thickness between about 5 μm and about 300 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.

Referring to FIG. 3, the cigarette 300 may include a tobacco rod 310, a support segment 320, a cooling segment 330, and a mouthpiece 340. However, this is only an example, and the cigarette 300 may further include other configurations in addition to the configurations 310 to 340 illustrated in FIG. 3, or some of the configurations 310 to 340 illustrated in FIG. 3 may be omitted.

In one embodiment the support segment 320 is located at the downstream end of the tobacco rod 310, the cooling segment 330 is located at the downstream end of the support segment 320, and the mouthpiece at the downstream end of the cooling segment 330. Although 340 may be located, the arrangement structure of the plurality of segments constituting the cigarette 300 is not limited thereto.

The tobacco rod 310 may be made of a sheet or may be made of a strand. In addition, the tobacco rod 310 may be made of a cut grass tobacco. The tobacco rod 310 may have a cylindrical shape, and smoke and / or aerosol may be generated as the tobacco rod 310 is heated.

The tobacco rod 310 may include, but is not limited to, aerosol-generating materials, flavoring agents, humectants, and / or additives such as organic acids, flavours such as menthol or humectants.

The support segment 320 may be a cellulose acetate filter. For example, the support segment 320 may be a tube-shaped structure that includes a hollow therein. The length of the support segment 320 may be employed in the appropriate length within the range of 4mm to 30mm, but is not limited thereto. Preferably, the length of the support segment 320 may be 10 mm, but is not limited thereto.

The diameter of the hollow included in the support segment 320 may be a suitable diameter within the range of 3mm to 4.5mm, but is not limited thereto. The hardness of the support segment 320 can be adjusted by adjusting the amount of plasticizer in the manufacture of the support segment 320.

In order to prevent the size of the support segment 320 from decreasing over time, the outline of the support segment 320 may be manufactured to be wrapped by a wrapper. Accordingly, the support segment 320 can be easily combined with other configurations.

In addition, the support segment 320 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 cooling segment 330 cools the aerosol generated as the heater heats the tobacco rod 310. Therefore, the user may inhale the aerosol cooled to the appropriate temperature when the cigarette 300 is inhaled.

The length or diameter of the cooling segment 330 may vary depending on the shape of the cigarette 300. For example, the length of the cooling segment 330 may suitably be employed within the range of 7 mm to 30 mm. Preferably, the length of the cooling segment 330 may be about 14 mm, but is not limited thereto.

The cooling segment 330 can be made of pure polylactic acid, or a combination of other degradable polymers and polylactic acid. For example, the cooling segment 330 may be manufactured by extrusion or weaving fibers. The cooling segment 330 can be fabricated in various forms to increase the surface area per unit area (ie, surface area in contact with the aerosol).

For example, the cooling segment 330 can be made by weaving fibers made of polylactic acid. In this case, the fragrance liquid may be applied to the fiber made of polylactic acid. Alternatively, the cooling segment 330 may be manufactured by using a separate fiber coated with a fragrance liquid and a fiber made of polylactic acid.

The length of the mouthpiece 340 may be appropriately employed within the range of 4mm to 30mm. For example, the length of the mouthpiece 340 may be about 12mm, but is not limited thereto.

The mouthpiece 340 may include a central portion 341 formed of an incompressible polymer material and an outer portion 342 formed of a compressed polymer material surrounding the central portion. In one embodiment, the center portion 341 may be a cylindrical structure, and the outer portion 342 may be a tubular structure including a hollow. At this time, the central portion 341 may be located in the hollow of the outer portion 342.

In one embodiment, the polymeric material may be cellulose acetate, paper or film, but is not limited thereto. Preferably, the mouthpiece 340 may include a central portion 341 formed of uncompressed cellulose acetate and an outer portion 342 formed of compressed cellulose surrounding the central portion.

The polymeric material can be compressed by compressing or solidifying with steam. The outer portion 342 formed of the compressed polymer material has a higher packing density and hardness than the central portion 341 formed of the uncompressed polymer material.

The aerosol generated as the tobacco rod 310 is heated is passed through a plurality of segments (eg, the support segment 320, the cooling segment 330, and the mouthpiece 340) in turn to the user. When the user inhales the cigarette 300, due to the suction resistance (RTD) by the plurality of segments constituting the cigarette 300, the aerosol may not be sufficiently delivered to the user. According to the present invention, the suction resistance (RTD) can be reduced by forming the central portion 341 of the mouthpiece 340 with a polymer material having a low packing density. That is, by using the mouthpiece 340 including the central portion 341 formed of an uncompressed polymer material, the migration of the aerosol can be increased.

In one embodiment, each of the tobacco rod 310, support segment 320, cooling segment 330 and mouthpiece 340 may be wrapped by a separate wrapper. In addition, the entire cigarette 300 may be double-packed by another wrapper surrounded by the wrapper surrounding the tobacco rod 310, the support segment 320, the cooling segment 330, and the mouthpiece 340, respectively. Can be. However, the manner in which the cigarette 300 and its constituent parts are wrapped by the wrapper is not limited thereto.

Referring to FIG. 4, the mouthpiece 400 may include a central portion 410 and an outer portion 420. One side of the mouthpiece 400 may be combined with a filter segment (eg, a cooling segment), and the other side may be a portion where the user's lips touch.

In one embodiment, the central portion 410 may be a cylindrical structure, and the outer portion 420 may be a tubular structure including a hollow. In this case, the central portion 410 may be located in the hollow of the outer portion 420.

The central portion 410 of the mouthpiece 400 may be formed of an incompressible polymer material, and the outer portion 420 may be formed of a compressed polymer material. For example, the polymeric material may be, but is not limited to, cellulose acetate, paper, or film. Preferably, the central portion 410 may be formed of uncompressed cellulose acetate, and the outer portion 342 may be formed of cellulose acetate.

The polymeric material can be compressed by compressing or solidifying with steam. The outer portion 420 formed of the compressed polymer material has a higher packing density and hardness than the central portion 410 formed of the uncompressed polymer material.

The mouthpiece 400 may be formed of a central portion 410 formed of an uncompressed polymer material and a compressed polymer material surrounding the central portion, thereby improving the restoring force and the elastic force of the mouthpiece 400. That is, when the user bites and smokes the mouthpiece 400 of the cigarette, it is possible to improve the emotional quality for the mouthpiece 400.

5A through 5B, the mouthpiece may include a central portion 511 and 712 and an

outer portion

521 and 522. In addition, the mouthpiece may further comprise

flavoring elements

531, 532.

The fragrance of

flavor elements

531, 532 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.

In one embodiment the flavor element 531 may be in the form of a capsule or a film. That is, the fragrance liquid of the fragrance element 531 may be included in the central portion 511 by being enclosed in a capsule or coated (or coated) on a film material. For example, the capsule's coating may be made of agar, pectin, sodium alginate, carrageenan, gelatin or guar gum, and the like. Moreover, a hardening adjuvant may further be used as a material which forms the film of a capsule. Here, the calcium chloride group etc. can be used as a gelling adjuvant, for example. In addition, a plasticizer may be further used as a material for forming the capsule film. Here, glycerin and / or sorbitol may be used as the plasticizer. Moreover, a coloring agent may further be used as a material which forms the film of a capsule. In addition, the film material may be polylactic acid (PLA), but is not limited thereto. The capsule may have a spherical or cylindrical shape.

In other embodiments, the

flavor elements

531, 532 may be in the form of fiber strands or fiber bundles. That is, the fragrance liquid of the

fragrance elements

531 and 532 may be applied to the fiber strands, and the fiber bundle to which the fragrance liquid is applied or the bundle of fibers which is a bundle of the fiber strands may be included in the central portion 511 and 712.

In addition, in the process of manufacturing the mouthpiece in another embodiment, the flavor may be produced by spraying the flavor liquid on the mouthpiece.

As the tobacco rod is heated, the resulting aerosol cools through the cooling segment and the cooled aerosol is delivered to the user through the mouthpiece. Therefore, when the

flavor elements

531 and 532 are added to the mouthpiece, the effect of enhancing the persistence of the flavor delivered to the user may be generated.

On the other hand, when the

fragrance elements

531 and 532 are present in the mouthpiece, the fragrance liquid of the

fragrance elements

531 and 532 may penetrate into the wrapper surrounding the mouthpiece, thereby weakening the strength, physical properties, and the like of the paper. In particular, when the fragrance element 531 is present in the mouthpiece in the form of a capsule, when a pressure is applied to the capsule by the user and the capsule is broken, the fragrance liquid inside the capsule may penetrate the wrapper surrounding the mouthpiece.

At this time, the mouthpiece is composed of a dual support structure, that is, the central portions 511 and 712 and the

outer portions

521 and 522, thereby preventing the perfume solution from penetrating into the wrapper. In other words, instead of forming the central portions 511 and 712 of an incompressible polymer material, the

outer portions

521 and 522 are formed of a compressed polymer material having a high packing density. Perfume of 532 can be prevented from penetrating the wrapper surrounding the mouthpiece.

Referring to FIG. 6, the cigarette 600 may include a tobacco rod 610, a first support segment 620, a second support segment 630, and a mouthpiece 640. However, this is only an example, and the cigarette 600 may further include other configurations in addition to the configurations 610 to 640 illustrated in FIG. 6, or some of the configurations 610 to 640 illustrated in FIG. 6 may be omitted.

Hereinafter, for convenience of description, content overlapping with FIG. 3 will be omitted.

In one embodiment a first support segment 620 is located at a downstream end of the tobacco rod 610, a second support segment 630 is located at a downstream end of the first support segment 620, and a second support segment ( The mouthpiece 640 may be located at a downstream end of the 630, but the arrangement structure of the plurality of segments constituting the cigarette 600 is not limited thereto.

The first support segment 620 and the second support segment 630 may be a tube-shaped structure including a hollow therein. The second support segment 630 may have a larger inner diameter than the first support segment 620. In one embodiment, the diameter of the first support segment 620 may be 7 mm to 9 mm, and the inner diameter may be about 2.0 mm to 4.5 mm. The diameter of the second support segment 630 may be 7mm to 9mm, the inner diameter may be about 3.0mm to 5.5mm, for example 4.0mm.

The inner diameter of the second support segment 630 has a larger value than the inner diameter of the first support segment 620, such that air passing through the hollow of the first support segment 620 is disposed in the hollow of the second support segment 630. It can be introduced and diffused. The air diffused in the hollow of the second support segment 630 may increase the contact area and the contact time with the outside air introduced through the perforation 631 as the deflection in the downstream direction of the cigarette 600 is reduced. . Accordingly, the cooling effect can be improved.

Perforations 631 may be formed in at least a portion of the second support segment 630. The hollow inside the second support segment 630 may be surrounded by a wall of cellulose acetate, and a perforation 631 may be formed in the wall of cellulose acetate.

In one embodiment the perforation 631 may be formed at a position 5 mm to 25 mm, preferably 15 mm to 20 mm, in the upstream direction from the downstream end of the second support segment 630. In addition, the perforation 631 may be composed of four to ten holes, for example, the perforation 631 may be composed of four, six or eight holes. However, the position of the punches 631 and the number of holes constituting the punches 631 are not limited thereto.

When the user inhales the cigarette 600, the outside air may enter the hollow of the second support segment 630 through the perforation 631 and move to the mouthpiece 640. In this case, the mouthpiece 640 includes a central portion 641 formed of an incompressible polymer material and an outer portion 642 formed of a compressed polymer material surrounding the central portion, wherein air introduced through the perforation 631 is introduced into the mouthpiece ( As it passes 640, it is concentrated and moved toward the center 641. That is, by concentrating air toward the center portion 641 where the suction resistance is relatively low, it is possible to prevent the migration amount of the aerosol from decreasing.

On the other hand, the air introduced from the outside through the perforation 631 may join the air introduced from the tobacco rod 610 end. That is, when the user inhales the cigarette 600, not only the air introduced from the cigarette rod 610 end but also the air introduced through the perforation 631 of the second support segment 630 is delivered to the user, thereby providing the aerosol. You can increase the amount of transition.
