Description

SUMMARY OF THE INVENTION The present invention provides a cigarette including a tobacco rod and a filter rod.

Recently, there has been an increasing demand for alternative methods to overcome the shortcomings of common cigarettes. For example, there is an increasing demand for methods of generating an aerosol by heating the aerosol-generating material within the cigarette rather than by burning the cigarette to generate an aerosol.

A cigarette includes a filter, and the filter serves to filter a specific component contained in the aerosol or cool the aerosol. If the filtering performance of the filter is too high, the amount of aerosol migration will decrease, and if the filtering performance is too low, there will be a problem that specific components contained in the aerosol will not be filtered.

As a result, research is progressing on filters that have appropriate performance by changing the components that make up the filter or by changing the structure of the filter.

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

A cigarette is disclosed that includes a tobacco rod and a filter rod connected to a downstream end of the tobacco rod.

A part of the filter rod according to this example consists of a cooling section, which contains sucrose as a cooling substance.

According to an embodiment of the present invention, the heated aerosol can be effectively cooled by using sucrose as the cooling substance that constitutes the cooling portion of the cigarette. As the heated aerosol passes through the cooling section, the temperature of the sucrose rises above its melting point, causing a phase change of the sucrose. In the process, the sucrose can cool the heated aerosol by absorbing ambient heat.

In addition, due to the property of absorbing moisture around the sucrose, the moisture absorbed by the sucrose is added to the aerosol passing through the cooling section, thereby increasing the amount of the aerosol.

Specifically, the controller 12000 controls the operations of the battery 11000, the heater 13000, and the vaporizer 14000 as well as other components included in the aerosol generator 10000. FIG. Also, the control unit 12000 can check the state of each configuration of the aerosol generation device 10000 and determine whether the aerosol generation device 10000 is in an operable state.

Control unit 12000 includes at least one processor. A processor may be implemented as an array of logic gates, and may also be implemented as a combination of a general-purpose microprocessor and a memory in which programs executed by the microprocessor are stored. It will also be appreciated by those skilled in the art to which the present embodiments pertain that other forms of hardware may be implemented.

Heater 13000 is heated by power supplied from battery 11000 . For example, if a cigarette is inserted into the aerosol generating device 10000, the heater 13000 may be located inside the cigarette. The heated heater 13000 can thus increase the temperature of the aerosol-generating substance within the cigarette.

Heater 13000 is also an electrical resistive heater. For example, heater 13000 may include electrically conductive tracks such that current flowing through the electrically conductive tracks heats heater 13000 . However, the heater 13000 is not limited to the above example, and can be applied without limitation as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 10000, or may be set to the desired temperature by the user.

However, in another example, the heater 13000 is also an induction heater. Specifically, the heater 13000 may include an electrically conductive coil for inductively heating the cigarette, and the cigarette may include a susceptor that is heated by the induction heater.

For example, the heater 13000 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and depending on the shape of the heating element, the inside or outside of the cigarette 20000 can be heated. can.

Some of the plurality of heaters 13000 are arranged to be inserted inside the cigarette 20000 and the rest are arranged outside the cigarette 20000 . Also, the shape of the heater 13000 is not limited to the shapes shown in FIGS. 1 to 3, and may be manufactured in various shapes.

The vaporizer 14000 heats the liquid composition to produce an aerosol, which is passed through the cigarette 20000 and delivered to the user. That is, the aerosol generated by the vaporizer 14000 travels along the airflow path of the aerosol generating device 10000, through which the aerosol generated by the vaporizer 14000 passes through the cigarette and is transmitted to the user. configured as

For example, the vaporizer 14000 can include, but is not limited to, a liquid reservoir, a liquid transfer means, and a heating element. For example, the liquid storage, liquid delivery means, and heating element may be included in the aerosol generating device 10000 as separate modules.

The liquid storage section can store a liquid composition. For example, a liquid composition can be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. The liquid storage unit is manufactured to detach/attach to/from the vaporizer 14000 and is also manufactured integrally with the vaporizer 14000 .

A heating element is an element for heating the liquid composition conveyed by the liquid conveying means. For example, the heating element can be a metal hot wire, a metal hot plate, a ceramic heater, etc., but is not limited to them. The heating element may also consist of a conductive filament, such as Nichrome wire, arranged by a structure wound around the liquid transfer means. The heating element can be heated by an electrical current supply to transfer heat to the liquid composition in contact with the heating element to heat the liquid composition. As a result, an aerosol can be generated.

For example, vaporizer 14000 may also be referred to as, but not limited to, a cartomizer or atomizer.

Meanwhile, the aerosol generator 10000 may further include a general-purpose configuration in addition to the battery 11000, the controller 12000, the heater 13000, and the vaporizer 14000. FIG. For example, the aerosol generating device 10000 may include a display capable of outputting visual information and/or a motor for outputting tactile information. Also, the aerosol generating device 10000 may include at least one sensor (puff sensor, temperature sensor, cigarette insertion sensor, etc.). In addition, the aerosol generator 10000 is also manufactured with a structure in which external air is introduced and internal gas is discharged even when the cigarette 20000 is inserted.

Although not shown in FIGS. 1 to 3, the aerosol generator 10000 may constitute a system together with a separate cradle. For example, the cradle is used to charge the battery 11000 of the aerosol generator 10000. Alternatively, the heater 13000 may be heated while the cradle and the aerosol generator 10000 are coupled.

Cigarette 20000 is similar to a typical combustible cigarette. For example, the cigarette 20000 is divided into a first portion containing an aerosol-generating substance and a second portion containing a filter or the like. Alternatively, the second portion of cigarette 20000 may also include an aerosol-forming material. For example, an aerosol-generating substance made into granules or capsules may be inserted into the second part.

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

By way of example, outside air is admitted through at least one air passageway formed in the aerosol generating device 10000 . For example, the opening and closing of the air passage formed in the aerosol generating device 10000 and/or the size of the air passage are adjusted by the user. Thereby, the amount of atomization, the feeling of smoking, etc. are adjusted by the user. As another example, the outside air can also flow into the interior of the cigarette 20000 through at least one hole formed on the surface of the cigarette 20000 .

An example of the cigarette 20000 will be described below with reference to FIG.

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

For example, the filter rod 22000 may include a first segment that cools the aerosol and a second segment that filters certain components contained within the aerosol. Also, if desired, the filter rod 22000 may further include at least one segment that performs other functions.

Cigarettes 20000 may be wrapped by at least one wrapper 24000 . The wrapper 24000 has at least one hole through which external air is introduced and internal gas is discharged. As an example, cigarettes 20000 are wrapped by one wrapper 24000 . As another example, cigarettes 20000 may be superimposed wrapped with two or more wrappers 24000 . For example, a first wrapper wraps tobacco rod 21000 and a second wrapper wraps filter rod 22000 . Then, the tobacco rod 21000 and the filter rod 22000 wrapped by the individual wrapper are combined, and the whole cigarette 20000 is rewrapped by the third wrapper. If tobacco rod 21000 or filter rod 22000 are each composed of multiple segments, each segment is wrapped with a separate wrapper. Then, the whole cigarette 20000, in which the segments wrapped by the individual wrappers are combined, is also rewrapped by a different wrapper.

Tobacco rod 21000 includes an aerosol-generating material. For example, the aerosol-forming material may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

Also, the tobacco rod 21000 may be added with a flavoring liquid such as menthol or a humectant by being sprayed onto the tobacco rod 21000 .

Tobacco rod 21000 may be manufactured in a variety of ways. For example, the tobacco rod 21000 is made of sheets as well as strands. Tobacco rod 21000 can also be made from shredded tobacco, which is a shredded tobacco sheet. Tobacco rod 21000 is also surrounded by a thermally conductive material. For example, the thermally conductive material can be, but is not limited to, metal foil such as aluminum foil. As an example, the thermally conductive material surrounding the tobacco rod 21000 can evenly distribute the heat transferred to the tobacco rod 21000 to improve the thermal conductivity applied to the tobacco rod, thereby improving the tobacco taste. sell. Also, the thermally conductive material surrounding the tobacco rod 21000 can function as a susceptor that is heated by an induction heater. At this time, although not shown, the tobacco rod 21000 may further include an additional susceptor in addition to the heat conductive material surrounding the outside.

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 can be a cylindrical rod or a tubular rod containing a hollow inside. The filter rod 22000 is also a recessed rod. If the filter rod 22000 is composed of multiple segments, at least one of the multiple segments is also made with a different shape.

The filter rod 22000 is also made to generate flavor. For example, a perfumed liquid may be sprayed onto the filter rod 22000 and a separate fiber coated with the perfumed liquid may be inserted into the filter rod 22000 .

Filter rod 22000 also includes at least one capsule 23000 . Here, the capsule 23000 performs the function of generating flavor and can also perform the function of generating aerosol. For example, the capsule 32400 also has a structure in which a content liquid containing perfume is covered with a film. Capsule 32400 can have a spherical or cylindrical shape, but is not limited thereto.

If the filter rod 22000 includes an aerosol cooling segment, the cooling segment is also made of a polymeric or biodegradable polymeric material. For example, the cooling segment may be made of pure polylactic acid alone, but is not so limited. Alternatively, the cooling segment may be fabricated from a multi-perforated cellulose acetate filter. However, the cooling segment is not limited to the above examples, and can apply without limitation as long as it can perform the function of cooling the aerosol.

Meanwhile, 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 one side of the tobacco rod 21000 opposite 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 during smoking from flowing to the aerosol generator (10000 in FIGS. 1 to 3). can be done.

FIG. 5 is a diagram illustrating an example of a cigarette including a cooler according to one embodiment.

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

In other embodiments, tube section 522 is coupled to the downstream end of tobacco rod 510, cooling section 521 is coupled to the downstream end of tube section 522, and acetate section 523 is coupled to the downstream end of cooling section 521. concatenated. That is, the segments may be positioned in 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 forming the filter rod 520 are not limited thereto.

On the other hand, the cigarette 5 is wrapped with a plurality of wrappers. The trumpets are made of general wrapping paper, either porous wrapping paper or non-porous wrapping paper.

For example, tobacco rod 510 is wrapped by a first wrapper and tube portion 522 is wrapped by a second wrapper. Also, the cooling part 521 is wrapped with a third wrapper, and the acetate part 523 is wrapped with a fourth wrapper.

The fifth trumpet is wrapped around 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 may be further wrapped by the fifth wrapper. Also, the sixth trumpet is covered with at least part of the fifth trumpet and the outer shell of the fourth trumpet. That is, at least a portion of the cooling portion 521 and the acetate portion 523 of the cigarette 5 can be further wrapped by the sixth wrapper.

The cigarette 5 has a diameter within the range of 5 mm to 9 mm and a length of about 48 mm, but is not so limited. For example, the length of tobacco rod 510 is about 12 mm, the length of tube portion 522 is about 10 mm, the length of cooling portion 521 is about 14 mm, and the length of acetate portion 523 is about 12 mm. Not limited.

Tobacco rod 510 includes an aerosol-forming material. For example, the aerosol-forming substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and oleyl alcohol.

Tobacco rod 510 may also include other additive substances such as flavorants, humectants and/or organic acids. For example, flavoring agents include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascara, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon. Oil, orange oil, mint oil, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cinnamon bark, ylang ylang, salvia, spearmint, ginger, coriander or coffee may be included. Humectants may also include glycerin or propylene glycol, and the like.

As an example, tobacco rod 510 may also be filled with a reconstituent tobacco sheet. As another example, tobacco rod 510 is filled with cut tobacco. Here, the cut tobacco is produced by finely cutting the plate-like leaf sheet. As another example, the tobacco rod 310 may also be filled with a plurality of tobacco strands that are finely chopped leaf sheets. For example, the tobacco rod 310 may be formed by aligning multiple tobacco strands in the same direction (parallel) or randomly.

In addition, a flavoring liquid such as menthol or a moisturizing agent may be sprayed into the center of the tobacco rod 510 before the tobacco rod 510 is wrapped with a wrapper.

Tube portion 522 is also a cellulose acetate filter. For example, the tube portion 522 is also a tubular structure containing a hollow inside. The length of the tube portion 522 is appropriately selected within a range of 4 mm to 30 mm, but is not limited thereto. Desirably, the length of tube portion 522 is as long as 10 mm, but is not so limited. The diameter of the hollow included in the tube portion 522 may be a suitable diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

The hardness of tube portion 522 is adjusted by adjusting the content of the plasticizer during manufacture of tube portion 522 . In addition, the tube part 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. Accordingly, when the heater is inserted, the phenomenon that the substance inside the tobacco rod 510 is pushed out can be prevented, and the cooling effect of the aerosol can be generated.

Cooling section 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 rises above its melting point, caramelization proceeds, and in the process it absorbs surrounding heat.

The cooling part 521 cools the aerosol generated by the heater heating the tobacco rod 510 . Therefore, the user can inhale the aerosol that has been 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 inhales air through the acetate portion 523 of the cigarette 5 inserted into the aerosol generator, the air flows into the cigarette 5 from the outside, and the heated tobacco rod 510 is heated by the heater. Aerosol is generated in the process of passing.

As the aerosol generated by the tobacco rod 510 passes through the cooling portion 521, the temperature of sucrose, which is a cooling substance contained in the cooling portion 521, rises. When the temperature of sucrose is higher than the melting point, the caramelization reaction proceeds, and in the process, it absorbs surrounding heat to cool the heated aerosol. Therefore, the user can inhale the aerosol that has been cooled to a suitable temperature.

In addition, the sucrose contained in the cooling part 521 has a property of absorbing and retaining surrounding moisture. As a result, the water absorbed by the sucrose is added to the aerosol passing through the cooling section 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 concentrate, the high osmotic pressure ensures high antiseptic properties and storage stability.

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

The beaded sucrose can have a spherical or pellet shape. The sheet of sucrose is made of either one of porous paper or edible film. Blocky sucrose can have a cylindrical, tubular, or briquette shape.

The length or diameter of the cooling part 521 may be variously determined according to the shape of the cigarette 5 . For example, the length of the cooling part 521 is suitably adopted within the range of 7 mm to 20 mm. Preferably, the length of the cooling portion 521 is approximately 14 mm, but is not limited thereto.

On the other hand, as shown in FIG. 5, the cooling part 521 is positioned upstream of the cigarette 5 from the tube part 522 and the acetate part 523, so that the tube part 522 and the acetate part 523 are melted or contracted by heat. can be prevented.

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

Referring to FIG. 6, the cooling unit 600 may include a first filter element 610, a second filter element 620 and a cooling substance 630. As shown in FIG.

A first filter element 610 may be positioned at one end of the cooling part 600 and a second filter element 620 may be positioned at the other end of the cooling part 600 . Also, the first filter element 610 and the second filter element 620 are spaced apart by a predetermined distance to form a cavity between the first filter element 610 and the second filter element 620 . A cooling substance 630 comprising sucrose may be located within 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 beaded cooling material 630 can have a spherical or pellet shape.

In one embodiment, a bead of cooling material 630 can be fabricated by laminating a sucrose layer onto a sucrose seed using Tangential Spray or Top Spray. . The bead-shaped cooling material 630 manufactured by such a method may have a spherical or pellet shape.

Also, the surface of the bead-like cooling substance 630 is coated. Film-forming polymers, gums (GUM), or starches (STARCH) are used as the coating agent for coating the surface of the cooling substance 630 . For example, shellac, hydroxypropyl methylcellulose (HPMC), corn starch, or a combination thereof may be used as a coating agent for coating the surface of the cooling substance 630 . Preferably, the coating agent that coats the surface of the cooling substance 630 is also shellac. Since the surface of the cooling substance 630 is coated, the cooling substance 630 can be easily inserted into the cooling unit 600, and the storage property of the cooling substance 630 is improved.

Also, at least a portion of the surface of the cooling substance 630 is formed with fine projections. A contact area between the cooling substance 630 and the aerosol passing through the cooling unit 600 may be increased by forming the fine protrusions on the surface of the cooling substance 630 . As a result, the cooling effect of the cooling substance 630 is improved.

In one embodiment, the bead-shaped cooling material 630 accounts for 30% to 35% of the total volume of the cooling unit 600 . The beaded cooling substance 630 also has a diameter of about 3mm to 5mm and a weight of about 0.3g to 1.0g.

Meanwhile, the first filter element 610 , the second filter element 620 and the cooling substance 630 included in the cooling unit 600 are also wrapped by at least one wrapper 640 .
