1 is a view showing a schematic configuration of a non-combustible smoking article to which a tube filter for smoking articles according to some embodiments of the present invention is employed.

Referring to FIG. 1 , a smoking article 100 may include a smoking material unit 110 , a support structure 120 , a cooling structure 130 , a mouthpiece unit 140 , and a wrapper 160 . Although not shown, at least one of the smoking material unit 110 , the support structure 120 , the cooling structure 130 , and the mouthpiece unit 140 is each as separate wrappers before being packaged by the wrapper 160 . can be packaged. For example, the smoking material unit 110 is wrapped by a smoking material wrapper (not shown), and at least one of the support structure 120 , the cooling structure 130 , and the mouthpiece unit 140 is provided with a filter wrapper (not shown). ) can be packed.

The diameter of the smoking article 100 is within the range of approximately 4 mm to 9 mm, and the length may be approximately 45 mm to 50 mm, but is not limited thereto. Specifically, the length of the smoking material unit 110 is about 5 mm to 20 mm (eg, about 12 mm), the length of the support structure 120 is about 4 mm to 15 mm (eg, about 10 mm), the cooling structure 130 ) may have a length of approximately 6 mm to 30 mm (eg, about 14 mm), and the length of the mouthpiece 140 may be approximately 5 mm to 20 mm (eg, about 12 mm), but is not limited thereto.

The smoking material unit 110 may be filled with leaf tobacco cut filler, a reconstituent 　 tobacco sheet and/or a plurality of tobacco strands in which the reconstituent 　 tobacco sheet and/or the reconstituent sheet are cut. For example, the smoking material unit 110 may be formed by combining a plurality of tobacco strands in the same direction (parallel) or randomly.

In some embodiments, the smoking material unit 110 may contain various substances such as flavoring agents such as menthol, wetting agents such as glycerin or propylene glycol, and organic acids in addition to the aerosol generating material.

The support structure 120 may be a tube-shaped structure including a hollow 120H therein. The outer diameter of the support structure 120 may be about 3 mm to 10 mm, for example, about 7 mm. The diameter of the hollow (120H) included in the support structure 120 may be an appropriate diameter within the range of approximately 2mm to 4.5mm. Preferably, the diameter of the hollow 120H may be about 2.5 mm, about 3.4 mm, or about 4.2 mm, but is not limited thereto.

The hardness of the support structure 120 may be adjusted by adjusting the content of the plasticizer when the support structure 120 is manufactured. In addition, the support structure 120 may be manufactured by inserting a structure such as a film or a tube made of the same or different material into the interior (ie, the hollow 120H).

The support structure 120 may be manufactured using cellulose acetate.

On the other hand, the support structure 120 according to some embodiments of the present invention may be an externally oriented tube filter that has been flavored through the outer surface (ie, the outer peripheral surface of the tube). In some other embodiments, the support structure 120 may be an external moisture-retaining tube filter that has been subjected to moisture treatment through the outer surface of the tube. In some other embodiments, the support structure 120 may be a flavoring and moisturizing tube filter. The flavored support structure 120 will be described in detail below.

The cooling structure 130 may serve as a cooling member for cooling the aerosol generated by the heater 130 heating the smoking material unit 110 . Accordingly, the user can inhale the aerosol cooled to an appropriate temperature.

In some embodiments, the cooling structure 130 may be fabricated by weaving polymer fibers. In this case, a fragrance liquid may be applied to the fibers made of the polymer. Alternatively, the cooling structure 130 may be manufactured by weaving a separate fiber coated with a flavoring solution and a fiber made of a polymer together.

In some embodiments, the cooling structure 130 may be made of pure polylactic acid (PLA) only. For example, the cooling structure 130 may be in the form of a three-dimensional woven fabric manufactured by using one or more fiber strands made of pure polylactic acid. Here, the number, thickness, length and shape of the fiber strands constituting the cooling structure 130 may vary. As the cooling structure 130 is formed of a woven polymer fiber or a crimped polymer sheet, the cooling structure 130 may include a single or a plurality of airflow channels extending in the longitudinal direction.

In some embodiments, the cooling structure 130 may be formed by winding a porous paper sheet. That is, inside the cooling structure 130, a wound porous paper sheet that allows the aerosol to pass through in the longitudinal direction of the cooling structure 130 may be located, and accordingly, the cooling structure 130 has a regular/irregular inside. Airflow paths having various shapes of patterns may be formed.

The mouthpiece 140 is positioned at the downstream end of the smoking article 100 to serve as a mouthpiece that finally delivers the aerosol delivered from the upstream to the user. In some embodiments, the mouthpiece unit 140 may be a cellulose acetate filter. Although not shown, the mouthpiece unit 140 may be manufactured as a recess filter.

In some embodiments, the mouthpiece 140 may include at least one capsule (not shown). The capsule may be, for example, a spherical or cylindrical capsule in which the liquid containing the fragrance is wrapped with a film.

In the process of manufacturing the mouthpiece 140 , the flavor may be generated by spraying the flavoring liquid to the mouthpiece 140 . Alternatively, a separate fiber coated with flavoring liquid may be inserted into the mouthpiece 140 .

In some embodiments, the amount of the flavoring liquid added to the mouthpiece unit 140 may be about 4 mg to 9 mg.

The aerosol generated by the smoking material unit 110 is cooled as it passes through the cooling structure 130 , and the cooled aerosol may be delivered to the user through the mouthpiece unit 140 . Therefore, when the flavoring liquid is added to the mouthpiece 140, the effect of enhancing the durability of the flavor delivered to the user may occur.

On the other hand, when the flavoring solution is added only to the mouthpiece 140 as in the prior art, there is a limit to the amount of flavoring solution input in the manufacturing process due to external contamination through transfer of the flavoring solution to the cigarette paper wrapping the outside of the filter, which will be described later in Table 9. As shown, as the storage period of the cigarette elapses, the menthol applied to the mouthpiece unit 140 is transferred to an adjacent unflavored tube filter, etc., and the amount of menthol transfer during smoking is rapidly reduced.

Accordingly, there have been attempts to perform flavoring treatment on the support structure 120 as well as the mouthpiece 140 . However, in the case of tube filters such as the support structure 120 , in general, when the hardness of the filter is low during the manufacturing process, the filter is broken or dented during cutting, and the filter is caught in the drum, so it has been difficult to manufacture continuously. In contrast, in order to increase the hardness of the tube filter, a process of manufacturing a tube filter by increasing the content of a plasticizer such as triacetin during the process and instantaneously hardening it through high-temperature steam treatment at about 100° C. to 200° C. is essential. As such, in the tube filter manufacturing process manufactured by high-temperature steam treatment, fragrance loss occurs due to high-temperature steam, which has made it difficult to apply fragrance.

Accordingly, smoking articles according to an embodiment of the present invention minimize the loss of flavor due to high-temperature steam during the process, and at the same time solve the problem of contamination around the tube filter by spraying hyangaek, and have a uniformly flavored support structure 120 provided do.

The flavoring liquid injected into the support structure 120 freely falls on the upper outer surface of the support structure 120 from the flavoring nozzle 40 of the apparatus for forming a tube filter 1 to be described later with reference to FIG. 7 , and then the support structure ( 120) can be absorbed into the interior. On the other hand, in order to increase the hardness of the support structure 120 , high-temperature and high-pressure steam is transferred to the support structure 120 by the steam nozzle 21 of the tube filter forming apparatus before the flavoring liquid is input to the support structure 120 . will be sprayed At this time, the orientation nozzle 40 may be spaced apart from the steam nozzle 21 of the tube filter forming apparatus by about 180 mm to 600 mm, preferably about 300 mm to 600 mm, in the longitudinal direction D1 of the tube filter.

In some embodiments, the menthol content (eg, weight) applied to the support structure 120 may be about 10% to 200% relative to the menthol content (eg, weight) of the mouthpiece 140 . Preferably, the menthol content applied to the support structure 120 may be about 100% to 150% of the menthol content of the mouthpiece unit 140 .

In some embodiments, the amount of menthol contained in the support structure 120 may be approximately 1 mg to 15 mg, preferably 2.5 mg to 9 mg, more preferably 3 mg to 5 mg. The amount of menthol contained in the support structure 120 may be slightly different depending on the lapse of the storage period of the cigarette.

On the other hand, it goes without saying that the amount of menthol contained in the above-described support structure 120 may vary depending on the length of the support structure 120 employed in the cigarette. Considering this point, the amount of menthol per unit length (mm) of the support structure applied to the support structure 120 may be approximately 0.2 mg to 1.1 mg, preferably 0.3 mg to 0.9 mg.

Furthermore, it goes without saying that the amount of menthol contained in the above-described support structure 120 may vary depending on the volume of the support structure 120 employed in the cigarette. In consideration of this point, the amount of menthol per unit volume (mm ³ ) of the support structure applied to the support structure 120 may be approximately 3ug to 40ug, preferably 7.5ug to 25ug.

Considering that the maximum flavoring amount applicable to the existing TJNS flavoring method is approximately 0.5mg/mm to 0.8mg/mm, when the tube filter is flavored according to embodiments of the present invention, it is about 1.2 times compared to the existing TJNS flavoring method It is possible to apply the maximum flavoring liquid to twice as much as possible.

In addition, when the cigarette of the externally-oriented tube filter according to the embodiments of the present invention is employed, it is possible to reduce the loss rate of menthol applied to the mouthpiece, and it is possible to increase the amount of menthol transfer to the cuticle, so that menthol taste during smoking can increase

Furthermore, since the flavoring treatment method with the tube filter according to the embodiments of the present invention allows the flavoring solution to freely fall on the outer peripheral surface of the tube filter, there is no complicated nozzle design for spraying the flavoring solution into the hollow inner surface of the tube. It is possible to put in, and there are no issues such as contamination of the working environment due to volatilization of the hyangaek or the contamination of the working environment during the hyangaek spraying process.

Meanwhile, the weight of the plasticizer (eg, triacetin) contained in the support structure 120 may be greater than the weight of the plasticizer contained in the mouthpiece unit 140 . For example, the support structure 120 may contain about 19% to 24% by weight of a plasticizer, and the mouthpiece 140 may contain about 6% to 15% by weight of the plasticizer.

On the other hand, when the moisturizing agent (glycerin, etc.) contained in the smoking material unit 110 and the plasticizer (triacetin, etc.) contained in the tube filter transfer from each segment to another segment and react with each other, odor such as acid odor may occur. However, the support structure 130 of the present invention contains a flavoring liquid such as menthol, as described later in Table 9, to minimize the transfer of ingredients between each segment during cigarette storage to alleviate the odor issue, or to mask this odor with menthol flavor. be able to do

A more detailed description of the support structure 120 will be described later with reference to FIG. 7 .

The wrapper 160 can prevent the smoking article 100 from being burned, and the holder of the aerosol generating device 1000 (see FIG. 1 ) can be prevented from being contaminated by the substances generated from the smoking article 100 . may be

The wrapper 160 may be a porous wrapper or a non-porous wrapper. For example, the thickness of the wrapper 160 may be about 40um to 80um, and the porosity may be about 5CU to 50CU, but is not limited thereto.

Meanwhile, as described above, at least one of the smoking material unit 110 , the support structure 120 , the cooling structure 130 , and the mouthpiece unit 140 is formed into separate wrappers before being packaged by the wrapper 160 . can be individually wrapped. For example, the smoking material unit 110 is packaged by a smoking material wrapper (not shown), and each of the support structure 120 , the cooling structure 130 , and the mouthpiece unit 140 is a first filter wrapper (not shown). , a second filter wrapper (not shown) and a third filter wrapper (not shown) may be packaged, respectively, but the manner in which the smoking article 100 and a part constituting it are packaged by the wrapper is not limited thereto.

In some embodiments, the wrappers may have different physical properties depending on the area they cover.

For example, the porosity of the first filter wrapper surrounding the support structure 120 may be about 5 CU to 50 CU, but is not limited thereto. In addition, an aluminum foil may be further included on the inner surface of the first filter wrapper.

Meanwhile, the second filter wrapper surrounding the cooling structure 130 and the third filter wrapper surrounding the mouthpiece 140 may be made of a thicker hard wrapper than the first filter wrapper, but is not limited thereto.

In some embodiments, the first filter wrapper and/or wrapper 160 has heat resistance with little change with temperature, oxidation resistance that does not oxidize, resistance to various chemicals, water repellency to water, or electrical insulation. Certain materials having properties may be internally added. Here, an example of the predetermined material may be silicon, but is not limited thereto.

FIG. 2 is a diagram illustrating a schematic configuration of a non-combustible smoking article to which a tube filter for smoking articles is employed according to another exemplary embodiment of the present invention.

Referring to FIG. 2 , the smoking article 200 may include a smoking material unit 210 , a support structure 220 , a cooling structure 230 , a mouthpiece unit 240 , and a wrapper 260 .

The smoking material unit 210 , the support structure 220 , the mouthpiece unit 240 , and the wrapper 260 are the smoking material unit 110 , the support structure 120 , and the mouthpiece unit 140 described with reference to FIG. 1 , respectively. ) and the wrapper 160, respectively, may have substantially the same configuration, and in the following, differences from the smoking article 100 described with reference to FIG. 1 will be mainly described for simplicity of explanation.

Unlike the cooling structure 130 described with reference to FIG. 1 , the cooling structure 230 in this embodiment may be a tube-shaped structure including a hollow 230H therein similarly to the support structure 220 . The cross-sectional shape of the hollow may be a polygon or a circle, but the size and shape of the hollow are not limited thereto.

The cooling structure 230 may border the support structure 220 and be located downstream of the support structure 220 . The diameter of the cooling structure 230 may be 6 mm to 9 mm, for example, about 7.0 mm. The inner diameter of the cooling structure 230 may be about 3.0 mm to 5.5 mm (eg, about 4.2 mm), but is not limited thereto.

At this time, the inner diameter of the cooling structure 230 may be greater than the inner diameter of the support structure (220). For example, the inner diameter of the support structure 220 may be about 2.5mm, the inner diameter of the cooling structure 230 may be about 4.2mm.

The cooling structure 230 may include a material through which an external gas can be introduced into the hollow of the cooling structure 230 from the outside, and the material may be a mixture of a plurality of materials. The material may be, for example, cellulose acetate tow. As another example, the material itself of the cooling structure 230 may be a material in which external gas cannot be introduced into the hollow of the cooling structure 230, and in this case, external air may be introduced into some regions of the cooling structure as needed. Perforations may be formed.

In some embodiments, the cooling structure 230 may be a paper tube having a tube shape with a hollow formed therein. In this case, the size of the inner diameter of the cooling structure 230 may be substantially smaller than the outer diameter of the cooling structure (230). For example, the outer diameter of the cooling structure 230 may be about 6.5mm to 7.5mm, and the inner diameter may be about 5.5mm to 7.0mm.

On the other hand, when a paper tube having an inner diameter of about 90% to 95% of the outer diameter as the cooling structure 130 is applied, the difference between the inner diameter of the support structure 120 and the inner diameter of the cooling structure 130 can be maximized, and thus the mainstream smoke diffusion effect And it is possible to further maximize the cooling effect of the mainstream smoke.

In some embodiments, a flavoring/moisturizing treatment may be applied to each of the support structure 220 and the cooling structure 230 . For example, the support structure 220 may be a directional tube filter, and the cooling structure 230 may be a moisturizing tube filter. Alternatively, the support structure 220 may be a moisturizing tube filter, and the cooling structure 230 may be a flavored tube filter. Alternatively, each of the support structure 220 and the cooling structure 230 may be a flavored moisturizing tube filter in which both the flavoring component and the moisturizing component are processed.

* Preferably, the support structure 220 may be a moisturizing tube filter, and the cooling structure 230 may be a flavored tube filter. That is, the flavored tube-shaped cooling structure 230 is located downstream from the moisturizing tube-shaped support structure 220 , but may be located upstream from the mouthpiece 240 which is a TJNS filter, and thus It is possible to minimize the loss of fragrance due to the heat of the aerosol.

For example, the support structure 220 and/or the cooling structure 230 has about 25% to 200% of the menthol content (eg, 2 mg to 8 mg) of the mouthpiece part 240 (eg, the mouthpiece part) When the menthol content of (240) is 7 mg, about 1.75 mg to 14 mg) of menthol may be contained.

As another example, the support structure 220 and/or the cooling structure 230 has a menthol content of the mouthpiece 240 (eg, 2 mg to 8 mg) of about 25% to 200% (eg, the mouthpiece portion). When the menthol content of (240) is 7 mg, about 1.75 mg to 14 mg) of a moisturizing agent may be contained.

As another example, the support structure 220 and/or the cooling structure 230 has about 25% to 200% of the menthol content (eg, 2 mg to 8 mg) of the mouthpiece 240 (eg, the mouthpiece). When the menthol content of the part 240 is 7 mg, about 1.75 mg to 14 mg) of a menthol moisturizer may be contained. The menthol moisturizer may include, for example, 35 wt% to 45 wt% of menthol, 5 wt% to 15 wt% of PG, and 45 wt% to 55 wt% of glycerin.

Referring to FIG. 3 , the smoking article 300 includes a front end filter segment (or front plug) 350 , a smoking material part 310 , a support structure 320 , a mouthpiece part 340 , and a wrapper 360 . can do.

The smoking material unit 310 , the support structure 320 , the mouthpiece unit 340 , and the wrapper 360 are the smoking material unit 110 , the support structure 120 , and the mouthpiece unit 140 described with reference to FIG. 1 , respectively. ) and the wrapper 160, respectively, may have substantially the same configuration, and in the following, differences from the smoking article 100 described with reference to FIG. 1 will be mainly described for simplicity of explanation.

Unlike the smoking articles 100 and 200 described with reference to FIGS. 1 and 2 , the smoking article 300 is a front-end filter segment 350 that borders the smoking material part 310 upstream of the smoking material part 310 . may further include.

In some embodiments, the front end filter segment 350 may be fabricated from cellulose acetate. The front end filter segment 350 may include a hollow through channel 350H extending sailingly from an upstream end to a downstream end. Channel 350H may be centered in front-end filter segment 350 . For example, the center of the channel 350H may coincide with the center of the front end filter segment 350 .

Although the channel 350H in this embodiment is shown to have a circular cross-sectional shape, the cross-sectional shape of the channel 350H is not limited thereto. For example, the cross-sectional shape of the channel 350H may be a three-lobed shape as shown in FIG. 9 .

In some embodiments, a flavoring/moisturizing treatment may be applied to the support structure 320 . For example, the support structure 320 may be a flavored tube filter, a moisturizing tube filter, or a flavored moisturizing tube filter.

For example, the support structure 320 may contain about 25% to 200% of the menthol flavor compared to the menthol content of the mouthpiece part 340 . In some embodiments, the menthol flavor may include about 60% to 80% (eg, 70%) of menthol, and about 20% to 40% (eg, 30%) of PG.

As another example, the support structure 320 may contain a moisturizing agent of about 25% to 200% compared to the menthol content of the mouthpiece part 340 . In some embodiments, the humectant may comprise about 70% to 90% (eg, 80%) of glycerin, and about 10% to 30% (eg, 20%) of PG.

As another example, the support structure 320 may contain about 25% to 200% of a menthol moisturizer compared to the menthol content of the mouthpiece part 340 . In some embodiments, the menthol moisturizer is menthol 35% to 45% (eg 40%), PG 5% to 15% (eg 10%) and glycerin 45% to 55% (eg, 50%) may be included.

In some embodiments, at least one of the front end filter segment 350 and the support structure 320 is a tube filter oriented by an outward facing method, which will be described later, and the mouthpiece portion 340 is oriented in a TJNS manner. It may be a filter. As a more specific example, the front end filter segment 350 may contain about 2 mg to 10 mg of menthol, and the support structure 320 may contain about 2 mg to 10 mg of menthol, and accordingly, the limit of the flavoring liquid input in the cigarette may be further increased. It can be increased, and it is possible to more effectively reduce the loss of the fragrance liquid in the smoking material part or the mouthpiece part as the storage period of the cigarette elapses. Furthermore, the humectant such as glycerin contained in the medium and the plasticizer such as triacetin contained in a large amount in the tube filter relieves the transfer from each segment to the other segment, so that the odor that may be caused by the reaction of glycerin and triacetin (e.g. For example, acid odor) can be minimized or it can be masked with menthol flavor.

For example, when the cigarette is inserted into the aerosol generating device 1000, the heater 1300 is inserted into the inner partial region of the cigarette TS, and the heated heater 1300 is the temperature of the aerosol generating material in the cigarette TS. can raise

In some embodiments, the heater 1300 may be an externally heated heater different from that shown in FIG. 4 . In this case, the heater 1300 may be disposed outside the cigarette TS inserted into the device. In addition, a plurality of heaters 1300 may be disposed in the aerosol generating device 1000 differently from the illustration. For example, all of the plurality of heaters 1300 may be disposed to be inserted into the cigarette TS or disposed outside the cigarette TS. As another example, some of the plurality of heaters 1300 may be disposed to be inserted into the cigarette TS, and others may be disposed outside the cigarette TS.

Meanwhile, of course, the shape of the heater 1300 is not limited to that shown in FIG. 4 . For example, the heater 1300 may have various shapes such as a tubular shape, a plate shape, a needle shape, or a rod shape, and the heater 1300 may heat the inside or the outside of the cigarette TS according to the shape of the heating element.

For example, the heater 1300 may be an electrically resistive heater. For example, the heater 1300 may include an electrically conductive track, and the heater 1300 may be heated as current flows through the electrically conductive track. As another example, the heater 1300 may be an induction heating type heater. Specifically, the heater 1300 may include an electrically conductive coil for heating the cigarette TS by an induction heating method, and the cigarette TS includes a susceptor (not shown) that can be heated by an induction heating type heater. may include

Referring to FIG. 5 , the aerosol generating device 2000 may include a battery 2100 , a controller 2200 , a heater 2300 , and a vaporizer 2400 .

Each of the battery 2100, the control unit 2200, and the heater 2300 of the aerosol generating device 2000 is substantially identical to each of the battery 1100, the control unit 1200, and the heater 1300 described with reference to FIG. 4 . In the following description, only differences from the aerosol generating apparatus 1000 described with reference to FIG. 4 will be mainly described for simplicity of explanation.

When the cigarette (TS) is inserted into the aerosol generating device (2000), the aerosol generating device (2000) operates the heater (2300) and/or vaporizer (2400), so that the cigarette (TS) and/or vaporizer (2400) may generate aerosols from The aerosol generated by the heater 2300 and/or vaporizer 2400 passes through the cigarette TS and is delivered to the user. When the cigarette is inserted into the aerosol generating device 2000, the heater 2300 is disposed in contact with or adjacent to the outer partial region of the cigarette TS, and thus the heated heater 2300 is an aerosol generating material in the cigarette TS. can increase the temperature of

The heater 2300 may be an electrically resistive heater or an induction heating heater, but is not limited thereto.

Meanwhile, the heater 2300 may be an internal heating type heater unlike that shown in FIG. 5 . In this case, the heater 2300 may be inserted into a partial area inside the cigarette TS. In addition, as described above with reference to FIG. 4 , it goes without saying that a plurality of heaters 2300 may be disposed in the aerosol generating device 2000 .

The vaporizer 2400 may generate an aerosol by heating the liquid composition, and the generated aerosol may be delivered to the user through the cigarette TS. That is, the aerosol generated by the vaporizer 2400 may move along the airflow passage of the aerosol generating device 2000 , and the aerosol generated by the vaporizer 2400 passes through the cigarette TS and the user It can be configured to be delivered to

In some embodiments, vaporizer 2400 may include, but is not limited to, a liquid reservoir, liquid delivery means and heating element. The liquid reservoir, liquid delivery means and heating element may be included in the aerosol generating device 2000 , for example as independent modules.

Meanwhile, although the vaporizer 2400 and the heater 2300 are illustrated in FIG. 5 as being arranged in parallel, the vaporizer 2400 and the heater 2300 may be arranged in a line. For example, vaporizer 2400 may be disposed upstream of heater 2300 in line with heater 2300 .

The above-described vaporizer 2400 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

The battery 2100 supplies power used to operate the aerosol generating device 2000 . For example, the battery 2100 may supply power to the heater 2300 or the vaporizer 2400 to be heated, and may supply power required for the controller 2200 to operate.

The controller 2200 may control the overall operation of the aerosol generating device 2000 . Specifically, the controller 2200 may additionally control the operation of the battery 2100 and the heater 2300 as well as the vaporizer 2400 .

On the other hand, in the aerosol generating apparatus 1000 and 2000 described with reference to FIGS. 4 to 5 , the batteries 1100 and 2100 , the controllers 1200 and 2200 , the heaters 1300 and 2300 and the vaporizer 2400 in addition to the general configuration more may be included. For example, the aerosol generating devices 1000 and 2000 may include a display capable of outputting visual information and/or at least one sensor (a puff sensor, a temperature sensor, a cigarette insertion sensor, etc.).

Meanwhile, although not shown in FIGS. 4 to 5 , the aerosol generating devices 1000 and 2000 are separate cradles (not shown) that can be used to charge the batteries 1100 and 2100 of the aerosol generating devices 1000 and 2000 . It is also possible to configure the system together with

The cigarette TS may have various structures like the smoking articles 100 , 200 , and 300 illustrated in FIGS. 1 to 3 , but is not limited thereto.

Meanwhile, the tube filter according to embodiments of the present invention may be applied not only to the non-combustible cigarette used with the above-described electronic cigarette device, but also as a component of the combustion cigarette to be described later with reference to FIG. 6 .

6 is a diagram illustrating the configuration of a combustion type smoking article 400 to which a tube filter for smoking articles according to some embodiments of the present invention is employed.

Referring to FIG. 6 , a smoking article 400 may include a smoking material unit 410 , a smoking material wrapper 410a , a filter for smoking articles 420 , and a tipping wrapper 430 .

Meanwhile, the filter 420 for smoking articles in this embodiment is illustrated as a dual filter having two filters 422 and 424, but is not limited thereto. For example, it is natural that the filter 420 for smoking articles may be provided as a mono filter including a single filter or a triple filter including three filters. Hereinafter, a case in which the filter 420 for smoking articles is configured as a dual filter will be described as an example.

The filter 420 for smoking articles is disposed downstream of the smoking material unit, and may be a region through which the aerosol material generated in the smoking material unit passes immediately before inhalation by the user.

The first filter 422 and the second filter 424 may be formed of various materials, for example, the first filter 422 and the second filter 424 may be a cellulose acetate filter.

In some embodiments, the first filter 422 and/or the second filter 424 may be a tube-shaped structure including a hollow therein, and in this case, the diameter of the hollow is in the range of about 2 mm to 4.5 mm. A suitable diameter may be employed.

For example, as shown in FIG. 6 , the first filter 422 in contact with the downstream end of the smoking material unit 410 is a tube filter having a hollow 422H, and is in contact with the downstream end of the first filter 422 and The second filter 424 located at the most downstream of the smoking article 400 may be a filter that does not have a hollow. Here, the first filter 422 may be a tube filter that has been flavored and/or moisturized through the outer surface of the tube, and the second filter 424 may be a filter flavored with a TJNS method.

In some embodiments, the length of each of the first filter 422 and the second filter 424 may be appropriately employed within the range of approximately 4 mm to 30 mm, and the first filter 422 and the second filter 424 may be suitably employed. ) Each diameter may be appropriately employed within the range of 5m to 8mm, but is not limited thereto. Preferably, the length of each of the first filter 422 and the second filter 424 may be about 15 mm, and the diameter of each of the first filter 422 and the second filter 424 may be about 5.4 mm.

In some embodiments, the first filter 422 may contain from about 19% to 24% by weight of a plasticizer, and the second filter 424 may contain from about 6% to 15% by weight of a plasticizer, It is not limited thereto.

The first filter 422 and the second filter 424 may be wrapped by wrappers 422a, 424a, and 426 . More specifically, the first filter 422 is wrapped by the first wrapper 422a, the second filter 424 is wrapped by the second wrapper 424a, and the first filter 422 and the second filter 424 may be bonded wrapped by a bonding wrapper 426 . In other words, the first filter 422 wrapped by the first wrapper 422a and the second filter 424 wrapped by the second wrapper 424a are further wrapped by the bonding wrapper 426 and physically coupled can be

The first wrapper 422a, the second wrapper 424a, and the combined wrapper 426 may apply the same wrapper to each other, but is not limited thereto, and wrappers having different characteristics may be applied. For example, some wrappers among the first wrapper 422a, the second wrapper 424a, and the bonding wrapper 426 may be porous wrappers, and some wrappers may be non-porous wrappers. As another example, some wrappers among the first wrapper 422a, the second wrapper 424a, and the combined wrapper 426 may be oil-resistant wrappers, and other wrappers may be wrappers that are not oil-resistant.

The smoking material portion 410 wrapped by the smoking material wrapper 410a and the filters 422 and 424 wrapped by the combination wrapper 426 may be combinedly packaged by the tipping wrapper 430 . That is, at least a portion of the smoking material unit 410 and the filters 422 and 424 may be further wrapped by the tipping wrapper 430 and physically coupled thereto.

The tipping wrapper 430 may be made of the same wrapper as any one of the first wrapper 422a, the second wrapper 424a, and the bonding wrapper 426, but is not limited thereto.

On the other hand, the smoking article 400 may have an elongated rod shape, and the length, diameter and circumference thereof may vary. For example, the smoking article 400 may have a length of about 45 mm to 100 mm (eg, about 70 mm), a diameter of about 4 mm to 6 mm (eg, about 5.4 mm), and a circumference of about 14 mm. to 19 mm (eg, about 17 mm). As another example, the diameter of the smoking article 400 may be about 7 mm to 9 mm (eg, about 7.8 mm), and the circumference may be about 22.5 mm to 26.5 mm (eg, about 24.5 mm).

7 is a view exemplarily showing a state in which flavoring is applied to a tube filter for smoking articles according to embodiments of the present invention, and FIGS. 8 and 9 are views showing a tube filter for smoking articles according to embodiments of the present invention. These are schematic diagrams to explain the process of flavoring.

The tube filter manufacturing apparatus 1 and the tubular rod (TF), etc., shown in FIGS. 7 to 9, have simplified and exaggerated configurations for clarity of explanation, and components that are not essential in the description of the present invention are omitted. became

7 to 9, the tube filter manufacturing apparatus 1 includes a tube filter outer molding case 10, a steam chamber 20, a tube filter molding rod 30, a flavoring nozzle 40, and a suction rail ( 50) may be included.

Although not shown, the tube filter manufacturing apparatus 1 supplies two filter tows, a material used for manufacturing a tube filter, into the tube filter outer molding case 10 with the tube filter molding rod 30 interposed therebetween. It may include a tow supply unit and the like.

In addition, the filter tows may undergo a pre-treatment process necessary to be manufactured into a tube filter through a pre-processor or the like before being supplied into the outer molded case 10 of the tube filter. For example, the filter tows may be moved to a stretching machine through a roller, and the stretching machine may supply the filter tows into the outer molding case 10 after stretching the filter tows.

In the tube filter manufacturing apparatus 1, the filter tows may move at a speed of approximately 500 RPM (rod per minute) to 2000 RPM. 1 RPM is a speed passing 1 Rod per minute, 1 Rod may be in the range of about 60 mm to 140 mm (eg, about 80 mm), but is not limited thereto.

The inner surface of the tube filter outer molding case 10 may have a cylindrical shape, and through this, the outer surface of the tubular rod TF may be formed. That is, the filter tows may be moved inside the tube filter outer molding case 10 and combined and cured by high temperature and/or high pressure steam to form a tubular rod TF.

On the other hand, as shown, a rod-shaped tube filter molding rod 30 is disposed inside the tube filter outer molding case 10, and accordingly, the tubular rod TF may have a tube shape with a hollow formed therein. . That is, the tube filter outer molding case 10 may define the outer surface of the tubular rod TF, and the tube filter molding rod 30 may serve to define an inner hollow of the tubular rod TF. The tubular rod TF formed by the tube filter manufacturing apparatus 1 may be completed as individual tube filters through a subsequent process such as cutting.

The steam chamber 20 may serve to supply high-temperature steam to the filter tows transferred from the inside of the tube filter outer molded case 10 to combine and harden the filter tows into a tubular rod. Steam from the steam chamber 20 may be supplied to the filter tows by means of a steam nozzle 21 communicating with the inside of the tube filter outer molding case 10 . The steam nozzle 21 may supply steam to each of the upper inner and lower inner sides of the outer tube filter case 10 as shown, but is not limited thereto. Although not shown, steam connectors for introducing high-temperature steam supplied from the outside into the steam chamber 20 may be formed in the steam chamber 20 .

In some embodiments, the steam nozzle 21 may supply steam at approximately 50° C. to 200° C. to the filter tows, but is not limited thereto.

After the flavoring nozzle 40 is formed into a tubular rod (TF) in which the filter tows are molded by the tube filter forming rod 30 and the steam chamber 20, the flavoring solution F containing menthol, etc. is applied to the tubular rod (TF). ), the flavoring liquid F can be injected into the tubular rod TF by free-falling on the upper outer surface (region F in FIG. 8) aligned in a direction perpendicular to the central axis TF_C and the ground.

In some embodiments, the flavoring solution (F) may include 40% to 80% by weight of menthol and 20% to 60% by weight of propylene glycol (PG), and the flavoring solution (F) is a tubular rod (TF) An amount of about 0.1 mg to 1.5 mg, preferably about 0.3 mg to 1.2 mg per 1 mm may be added to the upper outer surface of the .

On the other hand, the amount of flavoring liquid input may vary depending on the outer diameter and inner diameter of the tube to be manufactured. Accordingly, the flavoring liquid (F) is approximately 3ug to 40ug, preferably 7.5ug to 25ug per unit volume (mm ³ ) of the tubular rod (TF) to the upper outer surface of the tubular rod (TF). have.

The inner diameter of the flavoring nozzle 40 used for the flavoring liquid input may be approximately 0.8mm to 2.0mm, and the inner diameter of the flavoring nozzle 40 may be selected according to the flavoring liquid input amount. Specifically, when the flavoring liquid input is 0.1 mg to 0.4 mg per 1 mm, an inner diameter of the flavoring nozzle of about 0.8 mm to 1.2 mm (eg, about 0.9 mm) may be applied for uniform flavoring, and the flavoring liquid input amount per 1 mm In the case of 0.4 mg to 1.5 mg, an inner diameter of the orientation nozzle of about 1.2 mm to 1.6 mm (eg, about 1.3 mm) may be applied for uniform orientation and prevention of nozzle clogging.

In some embodiments, each of the tube filters cut and completed later by the above-described flavoring solution input may contain about 1 mg to 15 mg of menthol (which may vary depending on the menthol content in the flavoring solution), and accordingly The weight of menthol contained in the completed tube filter (eg, the support structure 130 ) may be greater than the weight of menthol contained in the mouthpiece unit 140 .

In some embodiments, the directing nozzle 40 is disposed downstream of the steam nozzle 21 as shown, wherein the directing nozzle 40 is from about 180 mm to 600 mm, preferably from about 300 mm to about 300 mm from the steam nozzle 21. 600 mm (eg, about 500 mm) may be disposed to be spaced apart. That is, the separation distance L1 between the directing nozzle 40 and the steam nozzle 21 may be approximately 180 mm to 600 mm, preferably approximately 300 mm to 600 mm (eg, about 500 mm). Through this, it is possible to minimize the fragrance loss rate that occurs during the manufacturing process of the tube filter. If a plurality of steam nozzles are provided as shown in FIG. 7 , the separation distance L1 is the steam nozzle located at the most downstream among the steam nozzles (ie, the steam nozzle closest to the directional nozzle among the steam nozzles). ) can be based on

On the other hand, when the flavoring solution F is simply freely dropped on the upper outer surface of the tubular rod TF as described above, it is difficult to uniformly spread the fallen flavoring solution F to the inner surface of the tubular rod TF, Furthermore, the flavoring fluid (F) does not sufficiently permeate into the tubular rod (TF) before the subsequent process after the flavoring treatment, so that the filter wrapper wetness or contamination of the working environment due to leakage of flavoring fluid occurs, which may cause difficulties in mass production.

In order to solve this difficulty, the present invention transfers the tubular rod TF through the suction rail 50 located on the lower outer surface of the tubular rod TF, and the suction means 52 provided in the suction rail body 51 ), the suction process of sucking air and moisture inside the tubular rod (TF) and discharging it to the outside of the tubular rod (TF) is performed together with the aforementioned flavoring treatment. As shown in Figure 8 or 9, the air and moisture inside the tubular rod (TF) are discharged through the suction process, and at the same time, the flavoring liquid (F) injected into the upper region of the tubular rod (TF) follows the tube shape. Diffusion or transition (S) to the lower region of the tubular rod (TF), through which the tubular rod (TF) can be oriented uniformly.

Here, the meaning of "performed together with the suction process and the flavoring process" can be broadly interpreted. That is, the flavoring liquid F by the flavoring nozzle 40 is dropped during the suction process by the suction rail, immediately after the suction process starts, at the same time as the suction process starts, or before the suction process starts. can

On the other hand, preferably, the flavoring liquid (F) falling by the flavoring nozzle 40 may be performed at a point in time when the suction process by the suction rail proceeds by about 60% to 90% (eg, about 70%). That is, the directing nozzle 40 may be disposed to be closer to the downstream end of the suction rail 50 than to the upstream end.

More specifically, taking the case where the length L2 of the suction rail 50 is about 500 mm as an example, the directing nozzle 40 is approximately 300 mm to 450 mm from the upstream end of the suction rail 50 (eg, about 350 mm). spaced apart and spaced from about 50 mm to 200 mm (eg, about 150 mm) from the downstream end.

In this case, the suction process before the fall of the flavoring solution serves to cool the tubular rod (TF) while transporting the tubular rod (TF). It can serve to evenly spread the liquid into the inner region of the tubular rod (TF).

In some embodiments, the suction rail 50 may extend approximately 100mm to 1,000mm (L2) in the longitudinal direction of the tubular rod TF (ie, the traveling direction D1 of the tubular rod TF), but this Of course, it is not limited.

The suction rail 50 may have various shapes and structures. For example, the suction rail 50 may have an arc shape surrounding at least a portion of the lower outer surface of the tubular rod TF. In this case, in order to maximize the suction efficiency and the flavoring solution diffusion efficiency, the upper end 51E of the suction rail 50 may be located at or at the same level as the central axis TF_C of the tubular rod TF.

Meanwhile, as illustrated in FIG. 9 and as described with reference to the smoking article 300 of FIG. 6 , the hollow TF_H of the tubular rod TF may have a trilobular cross-section.

As such, when the hollow (TF_H) of the tubular rod (TF) has a non-circular cross-section, it is difficult to apply the internal orientation method, which can be considered for improving the orientation processing process, and the conventional spraying method has a non-circular cross section. The method also decreases the flavoring efficiency. Unlike this method, in the case of the external orientation processing method according to the present invention, regardless of whether the hollow (TF_H) of the tubular rod (TF) has any shape such as a trilobal shape or a cross shape, the tubular rod (TF) is It can be flavored uniformly.

On the other hand, when the hollow (TF_H) of the tubular rod (TF) has a trilobular cross-section, in order to maximize the diffusion efficiency of the flavoring liquid, any one of the three lobes (Lf1, Lf2, Lf3) of the hollow (TF_H) ( Lf1) may be aligned between the central axis TF_C of the directing nozzle 40 and the tubular rod TF while the above-described suction process is performed.

Hereinafter, the configuration of the present invention and its effects will be described in more detail through Examples and Comparative Examples. However, these examples are for explaining the present invention in more detail, and the scope of the present invention is not limited to these examples.

Example 1

A flavoring solution having a menthol content of about 70% by weight was freely dropped on the upper outer surface of the tubular rod by using a flavoring nozzle 40 (refer to FIG. 7) and a suction rail 50, and a suction treatment was performed. A tubular rod having an outer diameter of about 7 mm and an inner diameter of about 2.5 mm was used, and as the tubular rod moves in the traveling direction (D1), the amount of flavoring solution injected into the tubular rod is about 0.1 mg per mm. The flavoring solution was free-falling from the flavoring nozzle and diffused into the tubular rod.

Example 2

A tubular rod was prepared under the same conditions as in Example 1, except that the amount of flavoring solution added was about 0.3 mg per mm.

Example 3

A tubular rod was prepared under the same conditions as in Example 1, except that the amount of flavoring solution added was about 1.2 mg per mm.

Example 4

A tubular rod was prepared under the same conditions as in Example 1, except that the amount of flavoring solution added was about 1.5 mg per mm.

Experimental Example 1: Setting of flavoring amount for uniform flavoring of tube filter

In order to evaluate the uniform orientation of the tubular rod, the results of the uniform orientation of the tubular rods treated according to Examples 1 to 4 are shown.

division Flavoring amount (mg) note Example 1 0.1 non-uniform flavor Example 2 0.3 uniform flavor Example 3 1.2 uniform flavor Example 4 1.5 Even flavoring / flavoring liquid dripping

As shown in Table 1, in the tubular rod of Example 1 having a flavoring amount of 0.1 mg per 1 mm (that is, 1 mg based on one tube filter of 10 mm length), flavor breakage occurred, and accordingly, uniformity in the tubular rod I could confirm that there was no flavor. In the tubular rod of Example 2, no breakage occurred, and in the tubular rod of Example 3, no breakage of fragrance occurred, and it can be seen that the flavoring solution was more uniformly processed in the tube filter. It was confirmed that the tubular rod of Example 4 was also uniformly flavored, but a phenomenon occurred that some of the free-falling flavoring liquid did not permeate into the tube and flowed down along the outer surface. Accordingly, it was confirmed that, in the external flavoring method, when a flavoring amount of 0.3 mg to 1.2 mg per 1 mm was applied, the flavoring characteristics were improved.

Example 5

A pipe is formed inside the tube filter forming rod 30, and the flavoring liquid is transferred through the pipe, but the flavoring liquid is dropped from the downstream end of the tube filter forming rod 30 to the inside of the tube through the hollow of the tubular rod. A flavoring method was performed, and a total of 48 mg of a flavoring solution having a menthol content of about 70% by weight was added to an 80mm tubular rod. The inner diameter of the directional nozzle of the conduit for dropping flavoring liquid was about 1.3 mm, and the directional nozzle was disposed at a position spaced about 200 mm from the steam nozzle.

The tubular rod treated with inward orientation was stored for about 24 hours, and then the upper region of the tubular rod and the lower region of the tubular rod were physically cut.

Example 6

The same amount of flavoring liquid as in Example 5 was added to the tubular rod, but the flavoring solution was freely dropped on the upper outer surface of the tubular rod through the flavoring nozzle 40 and the suction treatment was performed. Orientation was carried out at the same position and the same orientation nozzle inner diameter as in Example 5.

As in Example 5, the externally-oriented tubular rod was cut after storage for about 24 hours.

Example 7

The tubular rod was flavored, stored, and cut in the same manner as in Example 6, except that a total of 53 mg of flavoring solution was added to the 80 mm tubular rod.

Experimental Example 2: Evaluation of fragrance loss rate and fragrance diffusion

In order to evaluate the fragrance loss rate and the fragrance diffusion degree, the menthol content contained in the cut tube region in each of Examples 5 to 7 was analyzed and shown in Table 2.

Looking at the residual amount in the rod compared to the menthol input amount shown in Table 2, it can be seen that a high fragrance residual ratio was observed in both Examples 5 and 7 of the internally oriented method and the externally oriented method. Specifically, Examples The fragrance retention rate in 5 was shown to be about 94.6% (that is, the fragrance loss rate of about 3.6%), and the fragrance residual rate in Example 6 was about 91.4% (that is, the fragrance loss rate was about 8.6%), and carried out The fragrance retention rate in Example 7 was about 90.3% (ie, the fragrance loss rate of about 9.7%). In all of the examples, excellent fragrance retention characteristics of 90% or more were shown, and in particular, in the case of Examples 6 and 7 of the externally oriented method, in spite of high temperature and a suction environment, within 5% of Examples 5 and 5 of the internally oriented method There was only a difference in the residual ratio of the fragrance, and when considering the advantages in terms of aroma workability and economic feasibility, it was possible to sufficiently confirm the advantage of applying the external orientation method (however, in Examples 6 and 7 of the external orientation, the internal orientation was implemented A higher individual variation (CV) was observed compared to Example 5). On the other hand, it was confirmed that the outward-facing Examples 6 and 7 were superior to the inward-facing Example 5 in fragrance diffusion characteristics. Specifically, the menthol remaining in the upper region of the tubular rod in Example 5 is about 44.5% of the total menthol amount in the tubular rod, and the menthol remaining in the lower region is about 55.5% of the total menthol amount in the tubular rod in Example 6 The menthol content in the upper region is about 52.7% and the menthol content in the lower region is about 47.3% in Example 7, the menthol content in the upper region is about 51.8% and the menthol content in the lower region is about 48.2% They showed better fragrance diffusion properties.

This means that, in the case of internal orientation, the hyangaek is injected through the inner surface of the tubular rod lower region and then diffuses upward against gravity, whereas in the case of external orientation (and suction treatment), the hyangaek is injected through the outer surface of the upper region of the tubular rod It is predicted that this is because it spreads to the lower part through the suction force by gravity and suction treatment afterward.

Example 8

A tubular rod was manufactured in the same manner as in Example 7, except that the directing nozzle was disposed at a position spaced about 500 mm from the steam nozzle.

Example 9

A tubular rod was manufactured in the same manner as in Example 8, except that the outer surface of the rod was wrapped with a non-porous wrapper after the flavoring treatment.

Example 10

A tubular rod was manufactured in the same manner as in Example 8, except that a directional nozzle having an inner diameter of about 1.0 mm was used.

Example 11

The same as in Example 8, except that a flavoring solution having a menthol content of about 50% by weight was used, but a total of 74 mg of the flavoring solution was added to an 80 mm tubular rod (that is, the amount of menthol added was the same as in Example 8) A tubular rod was prepared in this way.

Example 12

A tubular rod was manufactured in the same manner as in Example 11, except that the outer surface of the rod was wrapped with a non-porous wrapper after the flavoring treatment.

Experimental Example 3: Flavor loss and flavoring method evaluation for individual variation reduction

Referring to Table 4, it can be seen that, when the other conditions are the same, a higher menthol residual rate was shown in the embodiment of the inward orientation compared to the outward orientation. It can be seen that there is a difference in the residual ratio according to the flavoring conditions, and in particular, the menthol residual ratio of Example 9 or Example 12 in which a filter wrapper is applied and the flavoring nozzle is spaced about 500mm from the steam nozzle is that of the internally flavored Example 5 Rather, it can be seen that higher values were observed. Furthermore, in the case of Example 9, a very low individual variation compared to the other outward-facing examples appeared, and the filter wrapper was performed after the external-facing treatment and before subsequent processes such as transfer and cutting. It was confirmed that all of the orientation workability, economic feasibility, and product uniformity can be secured when applying .

On the other hand, it was confirmed that the effect of increasing the menthol residual rate and reducing individual variation was slightly more advantageous in the case where the inner diameter of the aromatic nozzle was 1.0 mm than when the inner diameter was 1.3 mm, and the separation distance between the flavoring nozzle and the steam nozzle was 200 mm. It can also be confirmed that it is more advantageous in the case where the separation distance is 500mm than in the case of the case.

Experimental Example 4: Evaluation of tube filter physical properties for each flavoring condition

In order to examine the change in the physical properties of the tube filter for each flavoring condition, the weight, circumference, inner diameter, roundness and hardness of the tubular rods of Examples 7 to 12 were analyzed and shown in Tables 5 and 6.

As shown in Table 5 and Table 6, except that the weight of the tubular rod slightly increased according to the application of the filter paper, there was no significant difference in the physical properties depending on the orientation conditions and whether or not the filter paper was applied. was confirmed.

Comparative Example 1

A tubular rod was manufactured in the same manner as in Example 7, except that the directing nozzle was disposed at a position spaced about 100 mm from the downstream end of the suction rail.

Comparative Example 2

A tubular rod was manufactured in the same manner as in Example 7, except that the directing nozzle was disposed at a position spaced about 150 mm from the downstream end of the suction rail.

Experimental Example 5: Analysis of menthol residual rate according to flavoring conditions

In order to check the menthol residual ratio according to the external orientation process conditions of the tube filter, the menthol residual ratio according to the separation distance between the flavoring nozzle and the steam nozzle, the length of the suction rail, and the positional relationship between the suction rail and the flavoring nozzle were analyzed. indicated.

First, through Table 7, it is possible to confirm the degree of fragrance loss according to the separation distance between the flavoring nozzle and the steam nozzle. Referring to Examples 7 and 8, it can be seen that the menthol residual ratio slightly increased in Example 8, in which the spacing distance was 500 mm, compared to Example 7, in which the spacing distance was 200 mm. It was confirmed that there was a large difference depending on the length and the positional relationship between the suction rail and the orientation nozzle. Specifically, as the position of the orientation nozzle becomes farther from the downstream end of the suction rail (that is, toward the upstream end) or the length of the suction rail becomes longer than necessary, the menthol residual rate in the tube is noticeably lowered. can be checked This is because as the flavoring nozzle goes upstream of the suction rail, the flavor loss due to the influence of high-temperature steam increases. It is presumed to be due to the emission of However, it was confirmed that as the flavoring nozzle approaches the downstream end of the suction rail, the effect of diffusion of perfume by the suction is slightly reduced. In light of the above results, the separation distance between the flavoring nozzle and the steam nozzle is about 400mm to 600mm. and the length of the suction rail is about 300 mm to 800 mm, and the directional nozzle is at a position spaced apart from the upstream end of the suction rail by about 60% to 90% of the total length of the suction rail (for example, about 300 mm to 450 mm based on 500 mm) It was confirmed that the arrangement is advantageous in terms of the fragrance retention rate.

Comparative Example 5

For the example, a heated cigarette having the same structure as the smoking article 200 shown in FIG. 2, manufactured for testing, was used. The heated cigarette included a medium, a support structure, a cooling structure, and a mouthpiece, and a CA tube filter having an inner diameter of 2.5 mm was used as the support structure, and a CA tube filter having an inner diameter of 4.2 mm was used as the cooling structure.

The above-described flavoring process was not performed on the support structure with a length of 10mm, and a TJNS filter with a length of 12mm with 6mg of menthol flavoring was used for the mouthpiece.

Comparative Example 6

In Example 5, a tubular rod prepared by adding a total of 53 mg of a flavoring solution having a menthol content of about 70 wt% to an 80 mm tubular rod in the above-described internal orientation method in Example 5 was cut to a length of 10 mm and used as a support structure, except for the point, The same heated cigarette as in Comparative Example 5 was prepared.

Example 13

A heated cigarette was prepared in the same manner as in Comparative Example 5, except that the externally-oriented tubular rod prepared in Example 8 was cut to a length of 10 mm and used as a support structure.

Example 14

The same heated cigarette as in Comparative Example 5 was prepared, except that the tubular rod wrapped in filter wrapper was cut to a length of 10 mm and used as a support structure after the external orientation treatment prepared in Example 9.

Experimental Example 6: Evaluation of the physical properties of a cigarette to which an externally oriented tube filter is applied

In order to examine the change in the physical properties of the cigarette according to the external flavoring treatment of the tube filter, the weight, suction resistance, circumference, roundness and hardness of the cigarettes of Comparative Examples 5 to 6 and Examples 13 to 14 described above were analyzed. Table 8 shows.

As shown in Table 8, with the exception of a slight increase in weight and suction resistance due to the addition of the flavoring solution to the tube filter, and an increase in weight due to the application of the filter wrapper, Comparative Examples 5 and 14 that were not flavored It was confirmed that there was no significant difference in physical properties compared to the cigarette of Comparative Example 6 treated with internal flavoring, and that it met the standards for mass production.

Experimental Example 7: Analysis of menthol flavor transition pattern during storage of cigarettes

In order to confirm the menthol flavor transition pattern during storage and storage according to the tube filter flavor application, each segment of cigarettes 4 weeks after manufacture was separated and the menthol content of each segment was analyzed.

As shown in Table 9, the total amount of menthol in Example 14 increased by about 45% compared to the total amount of menthol in Comparative Example 5. Through this, it can be confirmed that the cigarette of Example 14 to which an externally flavored tube filter is applied has a significantly lower flavor loss rate over time, particularly in Acebu, than the cigarette of Comparative Example 5 to which an unflavored tube filter is applied. Yes. In terms of the menthol transition pattern between segments during cigarette storage, there was no significant difference between the external and internal flavoring methods, but considering the same amount of menthol in the tube in Comparative Examples 6 and 14, flavoring treatment It can be seen that in Example 14, in which the tube is wrapped with a filter wrapper, it is more advantageous to reduce the loss of flavor during storage and storage of the cigarette, which reduces the loss of flavor in subsequent processes such as filter transfer and cutting after the filter wrapper is flavored. It is expected that it is due to performing the role of

Experimental Example 8: Analysis of smoke components of cigarettes to which externally oriented tube filters are applied

For the analysis of the smoke components of cigarettes to which the externally-facing tube filter is applied, the smoke components of mainstream smoke during smoking of the cigarettes of Comparative Examples 5 to 6 and Example 14, 4 weeks after manufacture, were analyzed and shown in Table 10. The smoke collection for component analysis was repeated 3 times for each sample and 8 puffs for each time, and the component analysis results based on the average value of the collection results for 3 times are shown in Table 10. Cigarettes were tested according to HC (Health Canada) smoking conditions using an automatic smoking device in a smoking room with a temperature of about 20° C. and a humidity of about 62.5%.

As shown in Table 10, the amount of the components except for the menthol content did not show a significant difference in Comparative Examples 5 to 6 and Example 14, on the contrary, the menthol transfer amount was about 38% in Example 14 compared to Comparative Example 5, compared It was confirmed that it was increased by about 29% in Example 6. Considering that the amount of menthol in the tube in Comparative Example 6 and Example 14 is the same, Example 14 in which the filter wrapper was applied after the external flavoring treatment was menthol through mainstream smoke It was confirmed that it was most advantageous for maximizing the amount of implementation.

Example 15

For the Examples, a heated cigarette composed of a medium portion, a support structure, a cooling structure and a mouthpiece, prepared for testing, was used. The same tube filter as in Example 14 was used as the support structure, and the PLA woven fabric was used as the cooling structure. That is, the heated cigarette of Example 14 differs from the heated cigarette of Example 14 only in that the cooling structure is a PLA woven fabric.

Example 16

A heated cigarette was prepared in the same manner as in Example 14, except that a paper tube was applied as a cooling structure. The inner diameter of the paper tube is about 6 mm, and on-line perforation is applied to the area where the paper tube is located, and the air dilution rate of the paper tube is about 17%.

Experimental Example 9: Analysis of smoke components according to combination of externally facing tube filter and cooling structure

In order to confirm the difference in smoke components according to the cooling structure combination of the cigarettes according to Examples 14 to 16 to which the externally facing tube filter was equally applied as a support structure, the main smoke component during smoking of cigarettes 4 weeks after manufacture was analyzed.

As shown in Table 9, the amount of PG and moisture in the mainstream smoke did not show a significant difference between the examples, but the amount of nicotine, glycerin, and menthol transferred showed a difference depending on the application method of the cooling structure. Specifically, as the cooling structure, a paper tube was applied In Example 16, it can be seen that compared to Examples 14 and 15, it is relatively advantageous to increase the amount of nicotine, glycerin and menthol, and this result maximizes the difference between the inner diameter of the support part and the inner diameter of the cooling part when the paper tube is applied as a cooling structure. Therefore, it is expected that the thermal diffusion characteristics will be improved and the cooling effect will be maximized.

Experimental Example 10: Analysis of cooling effect according to combination with cooling structure

In order to evaluate the cooling effect during smoking of the cigarettes according to Examples 14 to 16 to which the outward-facing tube filter was equally applied as a support structure, the surface temperature and mainstream smoke temperature of each of the cigarettes were analyzed and shown in Table 12. Each of the surface temperature and mainstream smoke temperature represents the average value of the maximum temperature measured for each puff five times for each sample.

Referring to Table 12, it can be seen that in Example 16 to which a paper tube is applied as a cooling structure, the surface temperature and the mainstream smoke temperature are relatively low compared to Examples 14 and 15, and in particular, in the case of Example 16, in addition to simple numerical aspects, the same level It was confirmed that the heat or less heat was evenly spread over the entire hollow section of the cooling structure, so that the central portion of the mouthpiece was relatively relieved, and thus the atomization amount and the menthol transfer amount were also increased. Although not presented, in the case of the paper tube filter application case, there was a difference in the cooling effect and sensory characteristics according to the perforation process of the paper tube, that is, the air dilution rate. showed a linear increase, but when an air dilution rate higher than an appropriate value was applied, issues such as wasted sucking and decreased taste strength occurred.

Experimental Example 11: Evaluation of smoking sensory characteristics of cigarettes to which an externally-scented tube filter is applied

A CA tube filter with an inner diameter of 2.5 mm, which is not treated with flavoring, was employed as a support structure and a CA tube filter with an inner diameter of 4.2 mm as a cooling structure was employed in Comparative Example 5, and a CA tube filter with an inner diameter of 2.5 mm with menthol fragrance treated externally was used. Example 14, in which a CA tube filter with an inner diameter of 4.2 mm was employed as a support structure and a CA tube filter with an inner diameter of 4.2 mm as a cooling structure, a CA tube filter with an inner diameter of 2.5 mm with menthol flavoring treatment was employed as a support structure, and the air dilution rate was 17 as a cooling structure The sensory evaluation for suckability satisfaction, menthol strength during smoking, menthol satisfaction during smoking, scent persistence during smoking, taste taste during smoking, and satisfaction after smoking of the cigarettes of Example 16 in which % of the paper tube was employed was performed and shown in FIG. . Sensory characteristic evaluation was conducted for a total of 61 evaluation panel members using cigarettes for each Example 4 weeks after manufacture, and a total of 7 points was used as the standard.

As shown in FIG. 10 , it can be seen that in Examples 14 and 16, the sucking satisfaction, menthol strength and satisfaction, fragrance persistence, and overall satisfaction after smoking increased compared to Comparative Example 5, and the taste and taste such as acid odor and fiber odor were compared It can be confirmed that the decrease compared to Example 5.

When looking at the results in Examples 14 and 16, it was confirmed that it was slightly advantageous to apply the CA tube filter as a cooling structure in terms of suckability satisfaction and taste, whereas cooling in terms of menthol strength, menthol satisfaction and overall satisfaction It was confirmed that it is relatively advantageous to apply a paper tube as a structure.

From the above results, it can be seen that when the externally-scented tube filter according to embodiments of the present invention is applied to a cigarette, it can be seen that overall satisfaction with tobacco and flavor satisfaction can be improved.
