Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a drawing showing an example in which a cigarette is inserted into a holder.

With reference to FIG. 1, the cigarette 2 is inserted into the holder 1. If the cigarette 2 is inserted, the heater 130 is located inside the cigarette 2. Therefore, the heated heater 130 heats the aerosol-producing material of the cigarette 2, thereby producing an aerosol.

The cigarette 2 has a shape similar to that of a general combustion type cigarette. For example, the cigarette 2 can be divided into a first portion 140 containing an aerosol-producing material and a second portion 150 containing a filter or the like.

The entire first portion 140 is inserted inside the holder 1, and the second portion 150 can be exposed to the outside. Alternatively, only a part of the first portion 140 may be inserted into the holder 1, and a part of the first portion 140 and the second portion 150 may be inserted.

The user can inhale the aerosol with the second portion 150 in his mouth. At this time, the aerosol is generated by passing the outside air through the first portion 140, and the generated aerosol passes through the second portion 150 and is transmitted to the user's mouth.

External air also flows in through at least one air passage formed in the holder 1. Alternatively, outside air may flow in through at least one hole formed on the surface of the cigarette 2.

FIG. 2 is a block diagram showing an example of a cigarette.

Referring to FIG. 2, the cigarette 2 includes a tobacco rod 210, a first filter segment 221 and 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 and a cooling structure 222 and a second filter segment 223.

With reference to FIG. 2, the cigarette 2 is also packaged by trumpets 231, 232, 233, 234, 235, 236. For example, the tobacco rod 210 is packaged by the first trumpet 231 and the first filter segment 221 is also packaged by the second trumpet 232. The cooling structure 222 is also packaged by the third trumpet 233, and the second filter segment 223 is also packaged by the fourth trumpet 234.

The fifth trumpet 235 is covered with the outer shells of the first trumpet 231 and the second trumpet 232 and the third trumpet 233. That is, the tobacco rod 210 of the cigarette 2, the first filter segment 221 and the cooling structure 222 are further packaged by the fifth trumpet 235. Further, the sixth trumpet 236 is covered with at least a part of the fifth trumpet 235 and the outer shell of the fourth trumpet 234. That is, at least a portion of the cooling structure 222 of the cigarette 2 and the second filter segment 223 are further packaged by the sixth trumpet 236.

The first trumpet 231 and the second trumpet 232, the fifth trumpet 235 and the sixth trumpet 236 are made of ordinary rolling paper. For example, the first trumpet 231 and the second trumpet 232, the fifth trumpet 235 and the sixth trumpet 236 are also porous wrapping paper or non-porous wrapping paper. For example, the thickness of the first trumpet 231 is about 61 μm, the porosity is about 15 CU, the thickness of the second trumpet 232 is about 63 μm, and the porosity is also about 15 CU. Not limited to. Further, the thickness of the fifth trumpet 235 is about 66 μm, the porosity is about 10 CU, the thickness of the sixth trumpet 236 is 66 μm, and the porosity is about 17 CU. Not limited.

Further, the inner surface of the first trumpet 231 and / or the second trumpet 232 further includes an aluminum foil.

The third trumpet 233 and the fourth trumpet 234 are made of hard rolling paper. For example, the thickness of the third trumpet 233 is about 158 μm, the porosity is about 33 CU, the thickness of the fourth trumpet 234 is about 155 μm, and the porosity is about 46 CU, but they. Not limited to.

A predetermined substance may be internally added to the fifth trumpet 235 and the sixth trumpet 236. Here, as an example of the predetermined substance, silicon corresponds, but is not limited thereto. For example, silicon has properties such as heat resistance that does not change with temperature, oxidation resistance that is not oxidized, resistance to various chemicals, water repellency to water, and electrical insulation. However, even if it is not silicon, any substance having the above-mentioned characteristic particles can be applied (or coated) to the fifth trumpet 235 and the sixth trumpet 236 without limitation.

The fifth trumpet 235 and the sixth trumpet 236 can prevent the phenomenon that the cigarette 2 is burned. For example, if the tobacco rod 210 is heated by the heater 130, the cigarette 2 may be burned. Specifically, when the temperature rises above the ignition point of any one of the substance particles contained in the tobacco rod 210, the cigarette 2 is burned. Even in such a case, since the fifth trumpet 235 and the sixth trumpet 236 contain a nonflammable substance, the phenomenon that the cigarette 2 is burned is prevented.

Further, the fifth trumpet 235 can prevent the holder 1 from being contaminated by the substance particles generated by the cigarette 2. The user's puff creates liquid material particles in the cigarette 2. For example, the aerosol produced from the cigarette 2 can be cooled by outside air to produce liquid substance particles (eg, moisture, etc.). By packaging the tobacco rod 210 and / or the first filter segment 221 by the fifth trumpet 235, the liquid substance particles generated in the cigarette 2 are prevented from leaking to the outside of the cigarette 2. Therefore, the phenomenon that the inside of the holder 1 is contaminated by the liquid substance particles generated from the cigarette 2 is prevented.

The diameter of the cigarette 2 is within the range of 5 mm to 9 mm and the length is also, but is not limited to, about 48 mm. 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. However, it is not limited to that.

The structure of the cigarette 2 illustrated 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 and the cooling structure 222 and the second filter segment 223.

The tobacco rod 210 contains an aerosol-producing substance. For example, the aerosol-producing substance may contain at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

The tobacco rod 210 may also contain other additives such as flavoring agents, wetting agents and / or organic acids. For example, flavoring agents include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamon, celery, phenuglique, cascarilla, ebony, bergamot, geranium, honey essence, rose oil, vanilla, lemon. It may include oil, orange oil, mint oil, cinnamon bark, caraway, cognac, jasmine, camomile, menthol, cinnamon bark, ylang ylang, salvia, spearmint, ginger, coriander or coffee. The wetting agent may also contain glycerin, propylene glycol and the like.

As an example, the tobacco rod 210 is also filled with a reconstituent tobacco sheet.

As another example, the tobacco rod 210 is also filled with chopped tobacco. Here, chopped tobacco is produced by cutting a plate-shaped leaf sheet into small pieces.

As another example, the tobacco rod 310 is also filled with a plurality of tobacco strands in which the plate leaf sheet is finely chopped. For example, the tobacco rod 310 is formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly with each other.

For example, a plate-shaped leaf sheet is produced by the following process. First, an aerosol-producing substance (for example, glycerin, propylene glycol, etc.), a perfume liquid, a binder (for example, guar gum, xanthan gum, carboxymethyl cellulose (CMC), etc.), water, etc. were mixed by crushing the tobacco raw material. After making the slurry, the slurry is used to form a plate-shaped leaf sheet. When making the slurry, natural pulp or cellulose is added and it is also used when one or more binders are mixed. On the other hand, tobacco strands are produced by chopping or chopping the dried plate leaf sheet.

Tobacco raw materials are also tobacco leaf pieces, tobacco stalks, and / or tobacco fines produced during tobacco processing. In addition, the plate-shaped leaf sheet may contain other additives such as wood cellulose fibers.

5% to 40% of the aerosol-producing substance is added to the slurry, and 2% to 35% of the aerosol-producing substance remains in the plate-shaped leaf sheet. Desirably, 5% to 30% of the aerosol-producing material remains on the plate-like leaf sheet.

Further, before the process of packaging the tobacco rod 210 by the first trumpet 231, a perfume liquid such as menthol or a moisturizer can be sprayed and added to the center of the tobacco rod 210.

The first filter segment 221 is also a cellulose acetate filter. For example, the first filter segment 221 is also a tubular structure containing a hollow inside. As for the length of the first filter segment 221, an appropriate length is adopted in the range of 4 mm to 30 mm, but the length is not limited thereto. Desirably, the length of the first filter segment 221 can be as much as 10 mm, but is not limited thereto.

As the hollow diameter contained in the first filter segment 221, an appropriate diameter is adopted in the range of 2 mm to 4.5 mm, but the hollow diameter is not limited thereto.

The hardness of the first filter segment 221 can be adjusted by adjusting the content of the plasticizer during the production of the first filter segment 221.

Further, the first filter segment 221 can be manufactured by inserting a structure such as a film or a tube made of the same or irregularly shaped material inside (for example, hollow).

The first filter segment 221 is manufactured using cellulose acetate. As a result, when the heater 130 is inserted, the phenomenon that the internal substance of the tobacco rod 210 is pushed later can be prevented, and the cooling effect of the aerosol can be generated.

The cooling structure 222 cools the aerosol produced by the heater 130 heating the tobacco rod 210. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

The length or diameter of the cooling structure 222 can be variously determined by the morphology of the cigarette 2. For example, the length of the cooling structure 222 is appropriately adopted within the range of 7 mm to 20 mm. Desirably, the length of the cooling structure 222 can be as much as, but not limited to, about 14 mm.

The cooling structure 222 is also produced by weaving polymer fibers. In that case, the perfume liquid may be applied to the fibers produced by the polymer. Alternatively, the cooling structure 222 may be produced by weaving together another fiber coated with the perfume liquid and the fiber produced by the polymer.

Alternatively, the cooling structure 222 is also formed by a rolled 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. It is made.

By forming the cooling structure 222 with woven polymer fibers or rolled polymer sheets, the cooling structure 222 may include one or more channels extending in the longitudinal direction. Here, a channel means a passage through which a gas (eg, air or aerosol) passes.

For example, the cooling structure 222 consisting of a rolled polymer sheet is 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. The total surface area of the cooling structure 222 is between about 300 mm ² / mm and about 1000 mm ² / mm. Also, the aerosol cooling element is formed from a material with a specific surface area of between about 10 mm ² / mg and about 100 mm ^{2 / mg.}

On the other hand, the cooling structure 222 includes a thread containing a volatile flavor component. Here, the volatile flavor component is also menthol, but is not limited thereto. For example, the threads are 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 is also a cellulose acetate filter. The length of the second filter segment 223 is appropriately adopted within the range of 4 mm to 20 mm. For example, the length of the second filter segment 223 is as long as about 12 mm, but is not limited thereto.

In the process of producing the second filter segment 223, the flavor may be produced by injecting a perfume solution onto the second filter segment 223. Alternatively, another fiber coated with the perfume liquid may be inserted inside the second filter segment 223. The aerosol produced by the tobacco rod 210 is cooled by passing through the cooling structure 222, and the cooled aerosol is transmitted to the user via the second filter segment 223. Therefore, when the aroma element is added to the second filter segment 223, the effect of enhancing the persistence of the flavor transmitted to the user occurs.

FIG. 3 is a cross-sectional view of a cigarette including a wrinkled internal trumpet according to one embodiment.

With reference 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 merely an example, and the cigarette 300 includes other configurations other than the configurations 310 to 340 shown in FIG. 3, or a part of the configurations 310 to 340 shown in FIG. 3 is omitted. May be done.

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

The tobacco rod 310 is also made of sheets and is also made of strands. The tobacco rod 310 is also made of chopped tobacco in which a tobacco sheet is finely chopped. The tobacco rod 310 has a columnar shape, and when the tobacco rod 310 is heated, smoke and / or aerosol is generated.

Tobacco rod 310 may include, but is not limited to, aerosol-producing substances, flavoring agents, wetting agents and / or additives such as organic acids, and perfumes such as menthols or moisturizers.

The support segment 320 is also a cellulose acetate filter. For example, the support segment 320 is also a tubular structure containing a hollow inside. As for the length of the support segment 320, an appropriate length is adopted in the range of 4 mm to 30 mm, but the length is not limited thereto. Desirably, the length of the support segment 320 can be as much as 10 mm, but is not limited thereto.

The hollow diameter included in the support segment 320 is an appropriate diameter within the range of 3 mm to 4.5 mm, but is not limited thereto. The hardness of the support segment 320 is adjusted by adjusting the content of the plasticizer during the production of the support segment 320.

In order to prevent the size of the support segment 320 from decreasing over time, the outer shell of the support segment 320 can be manufactured to be wrapped by a trumpet. As a result, the support segment 320 can be easily combined with other configurations.

Further, the support segment 320 may be manufactured by inserting a structure such as a film or a tube of the same or irregularly shaped material inside (for example, hollow).

The cooling segment 330 cools the aerosol produced by the heater heating the tobacco rod 310. Therefore, the user can inhale the aerosol cooled to an appropriate temperature when inhaling the cigarette 300.

The length or diameter of the cooling segment 330 can be variously determined by the morphology of the cigarette 300. For example, the length of the cooling segment 330 is appropriately adopted within the range of 7 mm to 30 mm. Desirably, the length of the cooling segment 330 can be as much as, but not limited to, about 14 mm.

The cooling segment 330 is made from pure polylactic acid or in combination with other degradable polymers and polylactic acid. For example, the cooling segment 330 is also made through an extrusion method or a fiber weaving method. The cooling segment 330 is also made in various forms to increase the surface area per unit area (ie, the surface area in contact with the aerosol).

For example, the cooling segment 330 is also produced by weaving fibers produced by polylactic acid. In that case, the perfume liquid may be applied to the fibers produced by polylactic acid. Alternatively, the cooling segment 330 may be produced by using both the separate fiber coated with the perfume solution and the fiber produced by polylactic acid.

The mouthpiece 340 is also a cellulose acetate filter. For example, the mouthpiece 340 is also made by a recess filter, but is not limited thereto. The length of the mouthpiece 340 is appropriately adopted within the range of 4 mm to 30 mm. For example, the length of the mouthpiece 340 is as much as about 12 mm, but is not limited thereto.

In the process of producing the mouthpiece 340, the mouthpiece 340 may be produced so as to generate a flavor by injecting a perfume solution onto the mouthpiece 340. Alternatively, a separate fiber coated with a perfume solution may be inserted inside the mouthpiece 340. The aerosol produced by heating the tobacco rod 310 is cooled while passing through the cooling segment 330, and the cooled aerosol is transmitted to the user via the mouthpiece 340. Therefore, when the flavoring element is added to the mouthpiece 340, the effect of enhancing the persistence of the flavor transmitted to the user occurs. In addition, the mouthpiece 340 contains at least one capsule. Here, the capsule also has a structure in which an inner solution containing a fragrance is wrapped with a film. For example, the capsule has a spherical or cylindrical shape.

In one embodiment, the tobacco rod 310, the support segment 320, the cooling segment 330 and the mouthpiece 340 are each also packaged by a separate trumpet. Further, the entire cigarette 300 can be doubly packaged by another trumpet wrapped in the outer shell of the trumpet that wraps the tobacco rod 310, the support segment 320, the cooling segment 330, and the mouthpiece 340, respectively. However, the method in which the cigarette 300 and its constituent parts are wrapped by a trumpet is not limited thereto.

With reference to FIG. 3, the mouthpiece 340 is also double packaged. Specifically, the cellulose acetate 341 of the mouthpiece 340 is wrapped by the wrinkled inner trumpet 342, and the wrinkled inner trumpet 342 is also wrapped by the outer trumpet 343.

The wrinkles of the wrinkled inner trumpet 342 may form a passage 344 through which the aerosol moves between the wrinkled inner trumpet 342 and the outer trumpet 343 that surrounds it. That is, a passage 344 through which the aerosol moves can be formed around the circumferential surface of the mouthpiece 340 by the wrinkled internal trumpet 342.

The aerosol produced by heating the tobacco rod 310 passes through a plurality of segments (for example, the support segment 320, the cooling segment 330, and the mouthpiece 340) in sequence and is transmitted to the user. When the user inhales the cigarette 300, the aerosol is not sufficiently transmitted to the user due to the suction resistance (RTD) of the plurality of segments constituting the cigarette 300. According to the present invention, a passage 344 is formed between the wrinkled inner trumpet 342 that covers the cellulose acetate 341 of the mouthpiece 340 and the outer trumpet 343 that covers the wrinkled inner trumpet 342, and the aerosol passes through the passage 344. By passing through and being transmitted to the user, the amount of aerosol transfer can be increased.

In one embodiment, the wrinkle-like internal trumpet 342 has a wrinkle-to-wrinkle width of 0.1 mm to 5 mm and a wrinkle depth of 0.1 mm to 5 mm. Desirably, the wrinkle-like internal trumpet 342 has a wrinkle-to-wrinkle width of 1 mm to 3 mm and a wrinkle depth of 0.3 mm to 1 mm.

Further, the wrinkles of the wrinkled internal trumpet 342 are formed by the imprint roller. The wrinkle-to-wrinkle width and wrinkle depth of the wrinkle-shaped internal trumpet 342 are changed depending on the width between the uneven portions of the imprint roller, the depth of the uneven portion, and the stamping strength.

On the other hand, the external trumpet 343 and the mouthpiece 340 can be formed by covering only the mouthpiece 340 or simultaneously covering at least one other segment (for example, the cooling segment 330) constituting the cigarette 300 in addition to the mouthpiece 340. You can combine different segments.

FIG. 4 is a cross-sectional view of a mouthpiece including a wrinkled internal trumpet according to one embodiment.

With reference to FIG. 4, the mouthpiece 400 may include a cellulose acetate 410, a wrinkled inner trumpet 420 and an outer trumpet 430. As shown in FIG. 4, the wrinkled inner trumpet 420 can wrap the cellulose acetate 410 in a form that covers the outer shell of the cellulose acetate 410. Further, the wrinkled inner trumpet 420 is wrapped by the outer trumpet 430, so that the mouthpiece 400 is double-wrapped.

The wrinkles of the wrinkled inner trumpet 420 form a passage through which the aerosol moves between the wrinkled inner trumpet 420 and the outer trumpet 430 that surrounds it. That is, around the circumferential surface of the mouthpiece 400, a passage through which the aerosol moves is formed by the wrinkled internal trumpet 420.

That is, the aerosol produced by heating the aerosol-producing substance passes not only through the passage inside the cellulose acetate 410 but also through the passage formed between the wrinkled inner trumpet 420 and the outer trumpet 430 to the user. By being transmitted, the amount of aerosol transferred increases.

The wrinkles of the wrinkle-shaped internal trumpet 420 are formed by the imprint roller, and the wrinkle width 421 and the wrinkle depth 422 are also determined by the width between the concavo-convex portions of the imprint roller, the depth of the concavo-convex portion, the stamping strength, and the like. NS.

In one embodiment, the wrinkle-shaped internal trumpet 420 has a wrinkle-to-wrinkle width 421 of 0.1 mm to 5 mm and a wrinkle depth of 422 of 0.1 mm to 5 mm. Desirably, the wrinkle-like internal trumpet 420 has an inter-wrinkle width 421 of 1 mm to 3 mm and a wrinkle depth 422 of 0.3 mm to 1 mm.

On the other hand, the wrinkled cross section of the wrinkled internal trumpet 420 is not limited to the example shown in FIG. The wrinkled cross section of the wrinkled inner trumpet 420 has polygonal and semicircular shapes such as triangles, quadrangles, trapezoids.

FIG. 5 is a cross-sectional view of a cigarette including a cooling segment in which a perforation was formed according to one embodiment.

With reference to FIG. 5, the cigarette 500 may include a tobacco rod 510, a support segment 520, a cooling segment 530 and a mouthpiece 540. However, this is merely an example, and the cigarette 500 includes other configurations other than the configurations 510 to 540 shown in FIG. 5, or a part of the configurations 510 to 540 shown in FIG. 5 is omitted. May be done.

In the following, for convenience of explanation, the description of the contents overlapping with FIG. 3 will be omitted.

Perforations 531 are formed in at least a part of the cooling segment 530. In one embodiment, the perforations 531 are formed at positions separated from the downstream end of the cooling segment 530 in the upstream direction by 5 mm to 25 mm, preferably 15 mm to 20 mm. The perforation 531 is also composed of 4 to 10 holes, for example, the perforation 531 is also composed of 4, 6 or 8 holes. However, the position of the perforation 531 and the number of holes constituting the perforation 531 are not limited thereto.

When the user sucks in the cigarette 500, external air can flow into the cooling segment 530 through the perforations 531 and move to the mouthpiece 540. The air that has flowed in from the outside through the perforation 531 can merge with the air that has flowed in from the end of the tobacco rod 510.

Part of the air flowing in from the outside through the perforation 531 is transmitted to the user through the passage formed inside the cellulose acetate of the mouthpiece 540, and a part is formed between the inner wrinkle wrapper and the outer wrapper of the mass piece 540. It can be communicated to the user through the passageway.

When the user inhales the cigarette 500, not only the air flowing in from the end of the tobacco rod 510 but also the air flowing in through the perforation 531 of the cooling segment 530 is transmitted to the user, so that the amount of aerosol transfer can be increased. can.

The first support segment 620 and the second support segment 630 are also tubular structures containing a hollow inside. The second support segment 630 has a larger diameter than the first support segment 620. In one embodiment, the first support segment 620 has a diameter of 7 mm to 9 mm and an inner diameter of about 2.0 mm to 4.5 mm. The diameter of the second support segment 630 is 7 mm to 9 mm, and the inner diameter is about 3.0 mm to 5.5 mm, for example 4.0 mm.

Since the inner diameter of the second support segment 630 has a value larger than the inner diameter of the first support segment 620, the air that has passed through the hollow of the first support segment 620 is diffused while flowing into the hollow of the second support segment 630. sell. The air diffused while moving from the hollow of the first support segment 620 to the hollow of the second support segment 630 is separated from the external air flowing in through the perforation 631 by reducing the deflection of the cigarette 600 in the downstream direction. Contact area and contact time increase. This improves the cooling effect.

A perforation 631 is formed in at least a part of the second support segment 630. The hollow inside the second support segment 630 is surrounded by a wall made of cellulose acetate, and a perforation 631 is formed in the wall made of cellulose acetate.

In one embodiment, the perforations 631 are formed at positions separated from the downstream end of the second support segment 630 in the upstream direction by 5 mm to 25 mm, preferably 15 mm to 20 mm. The perforation 631 is also composed of 4 to 10 holes, for example, the perforation 631 is also composed of 4, 6 or 8 holes. However, the position of the perforation 631 and the number of holes constituting the perforation 631 are not limited thereto.

When the user sucks in the cigarette 600, external air can flow into the hollow of the second support segment 630 through the perforations 631 and move to the mouthpiece 640. The air that has flowed in from the outside through the perforation 631 can merge with the air that has flowed in from the end of the tobacco rod 610.

Part of the air that flowed in from the outside through the perforation 631 was transmitted to the user through the passage formed inside the cellulose acetate of the mouthpiece 640, and a part was formed between the wrinkle wrapper inside the mouthpiece 640 and the outside trumpet. It can be communicated to the user through the aisle.

When the user inhales the cigarette 600, not only the air flowing in from the end of the tobacco rod 610 but also the air flowing in through the perforation 631 of the second support segment 630 is transmitted to the user, thereby increasing the amount of aerosol transfer. sell.

Those who have ordinary knowledge in the technical field relating to this embodiment will understand that it can be embodied in a modified form within a range that does not deviate from the essential characteristics described above. Therefore, the disclosed method must be considered from a descriptive point of view, not from a limiting point of view. The scope of the present invention is shown in the claims, not in the above description, and all differences within the equivalent scope shall be construed as included in the present invention.
