Description

The present invention provides a cigarette that includes a tobacco rod and a filter rod.

Recently, there has been an increasing demand for alternative methods that overcome the shortcomings of common cigarettes. For example, there is an increasing demand for a method of producing an aerosol by heating an aerosol-producing substance in the cigarette, which is not a method of burning a cigarette to produce an aerosol.

The cigarette contains a filter, which serves to filter specific components contained in the aerosol or to cool the aerosol. If the filtering performance of the filter is excessively high, the amount of aerosol transfer is reduced, and if the filtering performance is excessively low, there is a problem that specific components contained in the aerosol are not filtered.

As a result, research on a filter having appropriate performance by changing the components constituting the filter or changing the structure of the filter is in progress.

An object to be solved by the present invention is to provide a cigarette that utilizes sucrose as a cooling substance constituting a cooling unit. The technical problem to be solved by this embodiment is not limited to the technical problem as described above, and other technical problems can be inferred from the following examples.

Disclosed is a tobacco rod and a cigarette containing a filter rod connected to the downstream end of the tobacco rod.

A part of the filter rod according to this embodiment is composed of a cooling part, and the cooling part contains sucrose as a cooling substance.

According to the embodiment of the present invention, the heated aerosol can be effectively cooled by using sucrose as a cooling substance constituting the cooling part of the cigarette. As the heated aerosol passes through the cooling section, the temperature of sucrose becomes higher than the melting point and a phase change of sucrose occurs. In the process, sucrose can cool the heated aerosol by absorbing the heat of the surroundings.

In addition, due to the property of absorbing water around sucrose, the amount of aerosol is increased by adding the water absorbed by sucrose to the aerosol that passes through the cooling unit.

For example, the cradle is used to charge the battery 11000 of the aerosol generator 10000. Alternatively, the heater 13000 may be heated with the cradle and the aerosol generator 10000 coupled.

The cigarette 20000 is similar to a typical combustion type cigarette. For example, the cigarette 20000 is divided into a first portion containing an aerosol-producing substance and a second portion containing a filter or the like. Alternatively, the second portion of the cigarette 20000 may also contain an aerosol-producing material. For example, an aerosol-producing substance made into granules or capsules may be inserted into the second portion.

The entire first portion is inserted into the aerosol generator 10000, and the second portion is also exposed to the outside. Alternatively, only a part of the first part may be inserted inside the aerosol generator 10000, or the whole of the first part and a part of the second part may be inserted. The user can inhale the aerosol with the second part in his mouth. At this time, the aerosol is generated by passing the outside air through the first portion, and the generated aerosol passes through the second portion and is transmitted to the user's mouth.

As an example, external air flows in through at least one air passage formed in the aerosol generator 10000. For example, the opening and closing and / or the size of the air passage formed in the aerosol generator 10000 is adjusted by the user. As a result, the amount of atomization, the feeling of smoking, and the like are adjusted by the user. As another example, outside air also flows into the inside of the cigarette 20000 through at least one hole formed on the surface of the cigarette 20000.

Hereinafter, an example of the cigarette 20000 will be described with reference to FIG.

FIG. 4 is a drawing showing an example of a cigarette.

The tobacco rod 21000 is also made of chopped tobacco in which a tobacco sheet is finely chopped. Also, the tobacco rod 21000 is surrounded by a heat conductive material. For example, the heat conductive material is also, but is not limited to, a metal foil such as an aluminum foil. As an example, the heat conductive material surrounding the tobacco rod 21000 can uniformly disperse the heat transferred to the tobacco rod 21000 to improve the thermal conductivity applied to the tobacco rod, thereby improving the tobacco taste. sell. Further, the heat conductive substance surrounding the tobacco rod 21000 can function as a susceptor heated by an induction heating type heater. At this time, although not shown, the tobacco rod 21000 may further contain an additional susceptor in addition to the heat conductive material surrounding the outside.

The filter rod 22000 is also a cellulose acetate filter. On the other hand, the shape of the filter rod 22000 is not limited. For example, the filter rod 22000 is both a columnar rod and a tubular rod containing a hollow inside. The filter rod 22000 is also a recessed rod. If the filter rod 22000 is composed of a plurality of segments, at least one of the plurality of segments is also manufactured with a different shape.

The filter rod 22000 is also manufactured so as to generate a flavor. As an example, the perfume liquid may be sprayed onto the filter rod 22000, and a separate fiber coated with the perfume liquid may be inserted inside the filter rod 22000.

Also, the filter rod 22000 includes at least one capsule 23000. Here, the capsule 23000 has a function of generating a flavor and can also perform a function of generating an aerosol. For example, the capsule 32400 also has a structure in which a content liquid containing a fragrance is covered with a film. Capsules 32400 can have spherical or cylindrical shapes, but are not limited thereto.

If the filter rod 22000 contains a segment that cools the aerosol, the cooling segment is also made of a polymeric or biodegradable polymeric. For example, cooling segments can be made with, but are not limited to, pure polylactic acid alone. Alternatively, the cooling segment is also made by a cellulose acetate filter in which a plurality of pores are formed. However, the cooling segment is not limited to the above-mentioned example, and can be applied without limitation as long as it can perform the function of cooling the aerosol.

On the other hand, although not shown in FIG. 4, the cigarette 20000 according to one embodiment may further include a front end filter. The front end filter is located on the tobacco rod 21000 on one side opposite to the filter rod 22000. The front end filter prevents the tobacco rod 21000 from detaching to the outside and prevents the aerosol liquefied from the tobacco rod 21000 from flowing to the aerosol generator (10000 in FIGS. 1 to 3) during smoking. Can be done.

FIG. 5 is a drawing showing an example of a cigarette including a cooling unit according to an embodiment.

Referring to FIG. 5, the cigarette 5 includes a tobacco rod 510 and a filter rod 520 connected to the downstream end of the tobacco rod 510. The filter rod 520 may include a cooling portion 521, a tube portion 522, and an acetate portion 523.

As illustrated in FIG. 5, in one embodiment, the cooling portion 521 is connected to the downstream end portion of the tobacco rod 510, the tube portion 522 is connected to the downstream end portion of the cooling portion 521, and the acetate portion 523 is connected to the downstream end portion. It is connected to the downstream end of the tube portion 522. That is, the segments may be located in the order of the tobacco rod 510, the cooling portion 521, the tube portion 522, and the acetate portion 523.

In another embodiment, the tube portion 522 is connected to the downstream end portion of the tobacco rod 510, the cooling portion 521 is connected to the downstream end portion of the tube portion 522, and the acetate portion 523 is connected to the downstream end portion of the cooling portion 521. Be connected. That is, the segments may be located in the order of the tobacco rod 510, the tube portion 522, the cooling portion 521, and the acetate portion 523.

However, the types of filter segments included in the filter rod 520 and the arrangement order of the filter segments constituting the filter rod 520 are not limited thereto.

On the other hand, the cigarette 5 is packaged by a plurality of trumpets. Multiple trumpets are made from common rolls and are also porous or non-porous rolls.

For example, the tobacco rod 510 is packaged by the first trumpet, and the tube portion 522 is packaged by the second trumpet. Further, the cooling unit 521 is packaged by the third trumpet, and the acetate unit 523 is packaged by the fourth trumpet.

The fifth trumpet is covered by the outer shells of the first trumpet, the second trumpet, and the third trumpet. That is, the tobacco rod 510, the tube portion 522, and the cooling portion 521 of the cigarette 5 can be further packaged by the fifth trumpet. Further, the sixth trumpet is covered with at least a part of the fifth trumpet and the outer shell of the fourth trumpet. That is, at least a part of the cooling portion 521 of the cigarette 5 and the acetate portion 523 can be further packaged by the sixth trumpet.

The diameter of the cigarette 5 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 510 is about 12 mm, the length of the tube portion 522 is about 10 mm, the length of the cooling portion 521 is about 14 mm, and the length of the acetate portion 523 is about 12 mm. Not limited.

Tobacco rod 510 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 510 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 510 is also filled with a reconstituent tobacco sheet. As another example, the tobacco rod 510 is 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 cut. For example, the tobacco rod 310 may be formed by a plurality of tobacco strands aligned with each other (parallel) or randomly aligned with each other.

Further, before the process of packaging the tobacco rod 510 by the trumpet, a perfume liquid such as menthol or a moisturizer may be sprayed and added to the center of the tobacco rod 510.

The tube portion 522 is also a cellulose acetate filter. For example, the tube portion 522 is also a tubular structure including a hollow inside. As for the length of the tube portion 522, an appropriate length is adopted within the range of 4 mm to 30 mm, but the length is not limited thereto. Desirably, the length of the tube portion 522 can be as much as 10 mm, but is not limited thereto. The hollow diameter contained in the tube portion 522 is an appropriate diameter in the range of 2 mm to 4.5 mm, but is not limited thereto.

The hardness of the tube portion 522 is adjusted by adjusting the content of the plasticizer during the production of the tube portion 522. Further, the tube portion 522 is manufactured by inserting a structure such as a film or a tube made of the same or different material into the inside (for example, hollow).

The tube portion 522 is manufactured using cellulose acetate. As a result, when the heater is inserted, the phenomenon that the internal substance of the tobacco rod 510 is pushed out can be prevented, and the cooling effect of the aerosol can be generated.

The cooling unit 521 contains sucrose (or sucrose) as a cooling substance. The melting point of sucrose is about 160 ° C to 180 ° C. When the temperature of sucrose exceeds the melting point, caramelization proceeds, and in the process, it absorbs the heat of the surroundings.

The cooling unit 521 cools the aerosol produced by the heater heating the tobacco rod 510. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

Specifically, when the cigarette 5 is inserted into the aerosol generator, the aerosol generator activates the heater to heat the tobacco rod 510 of the cigarette 5. When the user sucks in air through the acetate portion 523 of the cigarette 5 inserted into the aerosol generator, air flows into the cigarette 5 from the outside, and the inflowed air is heated by the heater to the tobacco rod 510. Aerosols are produced in the process of passing.

When the aerosol produced by the tobacco rod 510 passes through the cooling unit 521, the temperature of sucrose, which is a cooling substance contained in the cooling unit 521, rises. When the temperature of sucrose exceeds the melting point, the caramel reaction proceeds, and in the process, the heated aerosol can be cooled by absorbing the heat of the surroundings. Therefore, the user can inhale the aerosol cooled to a suitable temperature.

Further, the sucrose contained in the cooling unit 521 has a property of absorbing and retaining the surrounding moisture. As a result, the water absorbed by the sucrose is added to the aerosol passing through the cooling unit 521 to increase the amount of the aerosol, and the amount of the aerosol is maintained until the latter half of smoking.

In addition, when sucrose is a concentrated sugar solution, it has high antiseptic properties due to its high osmotic pressure, and stability in storage can be ensured.

In one embodiment, the sucrose contained in the cooling section 521 can have a bead shape, a sheet shape, or a block shape.

The bead-shaped sucrose can be spherical or pellet-shaped. The sheet-like sucrose is formed of any one of a porous paper or an edible film. The block-shaped sucrose can have a cylindrical shape, a tubular shape, or a charcoal-shaped shape.

The length or diameter of the cooling unit 521 can be variously determined by the form of the cigarette 5. For example, the length of the cooling unit 521 is appropriately adopted within the range of 7 mm to 20 mm. Desirably, the length of the cooling unit 521 is as much as, but not limited to, about 14 mm.

On the other hand, as shown in FIG. 5, by locating the cooling portion 521 upstream of the tube portion 522 and the acetate portion 523 of the cigarette 5, the tube portion 522 and the acetate portion 523 are melted or contracted by heat. Can be prevented.

FIG. 6 is an exemplary drawing showing a bead-like cooling material according to one embodiment.

With reference to FIG. 6, the cooling unit 600 may include a first filter element 610, a second filter element 620 and a cooling substance 630.

The first filter element 610 may be located at one end of the cooling unit 600, and the second filter element 620 may be located at the other end of the cooling unit 600. Further, the first filter element 610 and the second filter element 620 are separated by a predetermined distance, and a cavity is formed between the first filter element 610 and the second filter element 620. The cooling material 630 containing sucrose may be located in the cavity.

In one embodiment, the first filter element 610 and the second filter element 620 are also tubular structures containing a hollow inside, but the shapes of the first filter element 610 and the second filter element 620 are not limited thereto. ..

The cooling material 630 located in the cavity between the first filter element 610 and the second filter element 620 is also beaded. The bead-shaped cooling material 630 can have a spherical shape or a pellet shape.

In one embodiment, bead-like cooling material 630 can be made by laminating a sucrose layer on a sucrose seed using a Tangential Spray or Top Spray method. .. The bead-shaped cooling material 630 produced by such a method can have a spherical shape or a pellet shape.

Further, the surface of the bead-shaped cooling substance 630 is coated. As the coating agent for coating the surface of the cooling substance 630, film-forming polymers, gums (GUM) or starches (STARCH) are used. For example, as a coating agent for coating the surface of the cooling substance 630, shellac, Hydroxypropyl methylcellulose (HPMC), corn starch, or a combination thereof is used. Desirably, the coating agent that coats the surface of the cooling substance 630 is also shellac. By coating the surface of the cooling substance 630, it becomes easy to insert the cooling substance 630 into the cooling unit 600, and the storability of the cooling substance 630 is improved.
