1 is a diagram showing a schematic configuration of a non-combustion type smoking article employing a tube filter for smoking articles according to some embodiments of the present invention.

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 part 110, the support structure 120, the cooling structure 130, and the mouthpiece part 140 is wrapped in separate wrappers before being wrapped by the wrapper 160, respectively. can be wrapped 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 a filter wrapper (not shown). ) can be packed by

The smoking article 100 may have a diameter within a range of about 4 mm to 9 mm, and a length of about 45 mm to 50 mm, but is not limited thereto. Specifically, the length of the smoking material unit 110 is approximately 5 mm to 20 mm (eg, about 12 mm), the length of the support structure 120 is approximately 4 mm to 15 mm (eg, about 10 mm), the cooling structure 130 ) may have a length of about 6 mm to 30 mm (eg, about 14 mm), and the length of the mouthpiece part 140 may be about 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 from which the reconstituent leaf sheet is cut. For example, the smoking substance 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 materials such as a flavoring agent such as menthol, a humectant such as glycerin or propylene glycol, and an organic acid in addition to an 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 approximately 3 mm to 10 mm, for example, approximately 7 mm. The diameter of the hollow (120H) included in the support structure 120 may be appropriately employed within the range of about 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 manufacturing the support structure 120 . 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 type into the inside (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 deflected tube filter that is flavored through an outer surface (ie, an outer circumferential surface of the tube). In some other embodiments, the support structure 120 may be an external moisturizing tube filter subjected to moisturizing treatment through the outer surface of the tube. In some other embodiments, the support structure 120 may be a tube filter that has been flavored and moisturized. 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 substance 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, flavoring liquid may be applied to fibers made of polymer. Alternatively, the cooling structure 130 may be manufactured by weaving a separate fiber coated with flavoring liquid and a fiber made of a polymer together.

In some embodiments, the cooling structure 130 may be made of only pure polylactic acid (PLA). For example, the cooling structure 130 may have a shape of a three-dimensional weave fabricated 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 by woven polymer fibers or crimped polymer sheets, the cooling structure 130 may include one 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 rolled porous paper sheet that allows aerosol to pass along the length direction of the cooling structure 130 may be positioned, and accordingly, inside the cooling structure 130, regular / irregular Air flow paths having various shapes of patterns may be formed.

The mouthpiece part 140 is located at the downstream end of the smoking article 100, so that it can serve as a mouthpiece that finally delivers the aerosol delivered from the upstream to the user. In some embodiments, mouthpiece portion 140 may be a cellulose acetate filter. Although not shown, the mouthpiece part 140 may be made of a recess filter.

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

In the process of manufacturing the mouthpiece part 140, flavoring liquid may be sprayed onto the mouthpiece part 140 to generate flavor. Alternatively, a separate fiber coated with flavoring liquid may be inserted into the mouthpiece part 140 .

In some embodiments, the amount of flavoring liquid injected into the mouthpiece part 140 may be about 4 mg to 9 mg.

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

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

Accordingly, attempts have been made to flavor-process not only the mouthpiece part 140 but also the support structure 120 . However, tube filters such as the support structure 120 generally break or crush the filter during the manufacturing process if the hardness of the filter is low, and the filter is caught in the drum, making it difficult to manufacture continuously. Unlike, 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 hardening it instantaneously through a high-temperature steam treatment of about 100 ° C to 200 ° C is necessarily accompanied. In the manufacturing process of the tube filter manufactured by such high-temperature steam treatment, there has been difficulty in applying fragrance because the fragrance is lost by the high-temperature steam.

Therefore, the smoking articles according to the embodiment of the present invention minimizes the loss of flavor due to high-temperature steam during the process and at the same time solves the problem of contamination around the tube filter by spraying hyangaek, and is uniformly flavored. Provided with a support structure 120 do.

The flavoring liquid introduced into the support structure 120 is free-falling from the direction nozzle 40 of the tube filter forming apparatus 1 to be described later with reference to FIG. 7 to the upper outer surface of the support structure 120, and then the support structure ( 120) can be absorbed internally. On the other hand, in order to increase the hardness of the support structure 120, high-temperature and high-pressure steam is supplied to the support structure 120 by the steam nozzle 21 of the tube filter forming device as a step before flavoring liquid is injected into the support structure 120. will be sprayed At this time, the directional 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% of the menthol content (eg, weight) of the mouthpiece part 140 . Preferably, the menthol content applied to the support structure 120 may be about 100% to 150% of the menthol content of the mouthpiece part 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, and more preferably 3 mg to 5 mg. The amount of menthol contained in the support structure 120 may vary slightly depending on the storage period of the cigarette.

Meanwhile, it goes without saying that the amount of menthol contained in the aforementioned 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 aforementioned support structure 120 may vary depending on the volume of the support structure 120 employed in the cigarette. Considering 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 the embodiments of the present invention, it is about 1.2 times greater than the conventional TJNS flavoring method. It is possible to apply up to twice as many flavoring liquids.

In addition, when the cigarette of the externally flavored tube filter according to the embodiments of the present invention is employed, the loss rate of menthol applied to the mouthpiece can be reduced, and the amount of menthol transferred to the leg sheath can also be increased, thereby increasing the taste of menthol during smoking. can increase

Furthermore, since the flavoring treatment method for the tube filter according to the embodiments of the present invention free-falls the flavoring liquid on the outer circumferential surface of the tube filter, there is no complicated nozzle design for spraying the flavoring liquid into the hollow inner surface of the tube. It is possible to input, and there are no issues such as contamination of the working environment due to volatilization of hyangaek or contamination of the working environment in the process of spraying hyangaek, so it is possible to simplify the manufacturing process of the fragrance tube filter and to secure economic feasibility.

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

On the other hand, when the moisturizing agent (such as glycerin) contained in the smoking substance part 110 and the plasticizer (such as triacetin) contained in the tube filter are transferred from each segment to another segment and react with each other, odors such as acid odor may occur. However, the support structure 130 of the present invention minimizes the component transition between each segment during cigarette storage as described later in Table 9 by containing a scent liquid such as menthol to mitigate the off-flavor issue or to mask such off-flavor with menthol scent You can do it.

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 burning, and prevent the holder of the aerosol generating device 1000 (see FIG. 1) from being contaminated by 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 wrapper 160 may have a thickness of about 40 um to 80 um and a porosity of about 5 CU to 50 CU, but is not limited thereto.

On the other hand, 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 wrapped in separate wrappers before being wrapped by the wrapper 160. Each can be wrapped. For example, the smoking material unit 110 is wrapped 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). , The second filter wrapper (not shown) and the third filter wrapper (not shown) may be wrapped, respectively, but the smoking article 100 and parts constituting the smoking article 100 are wrapped by the wrapper are 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 hard paper thicker than the first filter wrapper, but are not limited thereto.

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

Referring to FIG. 2 , a 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 substance portion 210, the support structure 220, the mouthpiece portion 240, and the wrapper 260 are each of the smoking substance portion 110, the support structure 120, and the mouthpiece portion 140 described with reference to FIG. ) and the wrapper 160, respectively. Hereinafter, for simplicity of description, differences from the smoking article 100 described with reference to FIG. 1 will be mainly described.

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 contact 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 about 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 larger than the inner diameter of the support structure 220 . For example, the inner diameter of the support structure 220 may be about 2.5 mm, and the inner diameter of the cooling structure 230 may be about 4.2 mm.

The cooling structure 230 may include a material through which external gas flows 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 of the cooling structure 230 itself may be a material through which external gas cannot flow into the hollow of the cooling structure 230, and in this case, outside air may flow into some areas 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 inside. In this case, the inner diameter of the cooling structure 230 may be substantially smaller than the outer diameter of the cooling structure 230 . For example, the cooling structure 230 may have an outer diameter of about 6.5 mm to 7.5 mm and an inner diameter of about 5.5 mm to 7.0 mm.

On the other hand, when applying a branch pipe having an inner diameter of about 90% to 95% of the outer diameter as the cooling structure 130, 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 the resulting mainstream smoke cooling effect can be further maximized.

In some embodiments, 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 deflecting tube filter. Alternatively, each of the support structure 220 and the cooling structure 230 may be a scented moisturizing tube filter in which both a flavoring component and a moisturizing component are processed.

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

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

As another example, in the support structure 220 and/or the cooling structure 230, the menthol content of the mouthpiece part 240 (eg, 2mg to 8mg) compared to about 25% to 200% (eg, 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% to 45% by weight of menthol, 5% to 15% by weight of PG, and 45% to 55% by weight of glycerin.

The channel 350H may be located in the center of the pre-filter segment 350. For example, the center of channel 350H may coincide with the center of pre-filter segment 350 .

Although the channel 350H in this embodiment is illustrated as having 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 trilobal 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 flavoring tube filter, a moisturizing tube filter, or a flavoring 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 about 25% to 200% of the moisturizing agent compared to the menthol content of the mouthpiece part 340 . In some embodiments, the humectant may include about 70% to 90% (eg, 80%) glycerin and about 10% to 30% (eg, 20%) PG.

In some embodiments, the menthol moisturizer contains menthol 35% to 45% (eg 40%), PG 5% to 15% (eg 10%) and glycerin 45% to 55% (eg 10%). 50%) may be included.

In some embodiments, at least one of the front filter segment 350 and the support structure 320 is a tube filter flavored by an external flavoring method described later, and the mouthpiece portion 340 is flavored by a TJNS method. can be a filter. As a more specific example, the front 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. It can be increased, and as the storage period of the cigarette elapses, it is possible to more effectively reduce the loss of fragrance liquid in the smoking material part or the mouthpiece part. Furthermore, the transfer of a humectant such as glycerin contained in the medium part and a plasticizer such as triacetin contained in a large amount in the tube filter is alleviated from the transfer from each segment to another segment, thereby reducing the odor that may occur due to the reaction of glycerin and triacetin (eg For example, acid odor) can be minimized or masked with a menthol scent.

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

The battery 2100 supplies power used for the operation of the aerosol generating device 2000. For example, the battery 2100 may supply power so that the heater 2300 or the vaporizer 2400 may be heated, and may supply power necessary 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 vaporizer 2400 as well as the battery 2100 and the heater 2300 .

Meanwhile, the aerosol generating devices 1000 and 2000 described with reference to FIGS. 4 and 5 include batteries 1100 and 2100, controllers 1200 and 2200, heaters 1300 and 2300, and vaporizers 2400, as well as general-purpose configurations. may further be included.

Meanwhile, although not shown in FIGS. 4 and 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. You can also configure a system with

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

Meanwhile, the tube filter according to embodiments of the present invention may be applied as one component of a combustion type cigarette to be described later with reference to FIG. 6 as well as a non-combustion type cigarette used together with the above-described electronic cigarette device.

6 is a view exemplarily showing the configuration of a combustion type smoking article 400 in 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 substance unit 410, a smoking substance wrapper 410a, a smoking article filter 420, and a tipping wrapper 430.

Meanwhile, the smoking article filter 420 in this embodiment is shown as a dual filter provided with two filters 422 and 424, but is not limited thereto. For example, it is natural that the filter 420 for a smoking article may be provided with a monofilament composed of a single filter or a triple filter provided with 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 smoking article filter 420 may be disposed downstream of the smoking material unit and may be an area through which the aerosol material generated from the smoking material unit passes immediately before the user inhales.

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 cellulose acetate filters.

In some embodiments, the first filter 422 and/or the second filter 424 may be a tubular structure including a hollow therein, in which case the diameter of the hollow is within a range of about 2 mm to 4.5 mm. An appropriate diameter can be employed in

For example, as shown in FIG. 6, the first filter 422 in contact with the downstream end of the smoking substance unit 410 is a tube filter having a hollow 422H, and is in contact with the downstream end of the first filter 422. The second filter 424 positioned at the most downstream of the smoking article 400 may be a non-hollow filter. Here, the first filter 422 may be a tube filter flavored and/or moisturized through the outer surface of the tube, and the second filter 424 may be a filter flavored in the TJNS method.

In some embodiments, the length of each of the first filter 422 and the second filter 424 may be appropriately employed within a range of approximately 4 mm to 30 mm, and the first filter 422 and the second filter 424 ) Each diameter may be appropriately employed within a range of 5 m to 8 mm, but is not limited thereto. Preferably, each of the first filter 422 and the second filter 424 may have a length of about 15 mm, and a 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 about 19% to 24% plasticizer by weight, and the second filter 424 may contain about 6% to 15% plasticizer by weight, Not limited to this.

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 bonded 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 a binding wrapper 426 and physically bonded. It can be.

The same wrapper may be applied to the first wrapper 422a, the second wrapper 424a, and the combined wrapper 426, but the wrapper having different characteristics may be applied without being limited thereto. For example, some of the first wrapper 422a, the second wrapper 424a, and the combined wrapper 426 may be porous wrappers, and some other wrappers may be non-porous wrappers. As another example, some of the first wrapper 422a, the second wrapper 424a, and the combined wrapper 426 may be oil-resistant wrappers, and other wrappers may not be oil-resistant.

The smoking material portion 410 wrapped by the smoking material wrapper 410a and the filters 422 and 424 wrapped by the combined wrapper 426 may be combined and packed by the tipping wrapper 430 . That is, at least a portion of the smoking substance unit 410 and the filters 422 and 424 may be further wrapped by the tipping wrapper 430 and physically coupled to each other.

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

Meanwhile, the smoking article 400 may have an elongated rod shape, and its length, diameter and circumference may vary. In one example, smoking article 400 may be approximately 45 mm to 100 mm long (eg, approximately 70 mm), approximately 4 mm to 6 mm diameter (eg, approximately 5.4 mm), and approximately 14 mm in circumference. to 19 mm (eg, about 17 mm). As another example, the smoking article 400 may have a diameter of approximately 7 mm to 9 mm (eg, about 7.8 mm) and a circumference of approximately 22.5 mm to 26.5 mm (eg, about 24.5 mm).

7 is a view 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 a view showing a tube filter for smoking articles according to embodiments of the present invention. These are schematic diagrams to explain the process of flavoring.

In the tube filter manufacturing apparatus 1 and the tubular rod (TF) shown in FIGS. 7 to 9, each configuration is simplified and exaggerated for clarity of explanation, and components that are not essential in the description of the present invention are omitted. It 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 directional nozzle 40, and a suction rail ( 50) may be included.

Although not shown, the tube filter manufacturing apparatus 1 supplies two filter tows, which are materials used for manufacturing the tube filter into the tube filter external 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 be subjected to a pretreatment process required to be manufactured into a tube filter through a preprocessor or the like before being supplied into the tube filter outer molding case 10. For example, the filter tows may be moved to the stretching machine through rollers, and the stretching machine may stretch the filter tows and then supply them into the tube filter outer molding case 10 .

Filter tows in the tube filter manufacturing apparatus 1 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, and 1 Rod may range from approximately 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, through which the outer surface of the tubular rod (TF) may be molded. That is, the filter tows may be moved inside the tube filter outer molding case 10 and bonded and hardened 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 external molding case 10, and accordingly, the tubular rod TF may have a tube shape with a hollow inside. . That is, the tube filter outer molding case 10 defines the outer surface of the tubular rod (TF), and the tube filter molding rod 30 may serve to define the 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 supply high-temperature steam to the filter tows transported inside the tube filter outer molding 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 a steam nozzle 21 communicating with the inside of the tube filter outer molded case 10 . The steam nozzle 21 may supply steam to the upper inside and the lower inside of the outer molded case 10 of the tube filter, respectively, 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 about 50° C. to 200° C. to the filter tows, but is not limited thereto.

After the filter tows are formed into a tubular rod (TF) by forming the filter tows by the tube filter molding rod 30 and the steam chamber 20, the flavoring liquid (F) containing menthol or the like is applied to the tubular rod (TF). ), the flavoring liquid F may be injected into the tubular rod TF by freely falling on the upper outer surface (region F in FIG. 8) aligned in the direction perpendicular to the central axis TF_C and the ground.

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

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

The inner diameter of the flavoring nozzle 40 used to inject the flavoring liquid may be approximately 0.8 mm to 2.0mm, and the inner diameter of the flavoring nozzle 40 may be selected according to the input amount of the flavoring liquid. Specifically, when the flavoring liquid input amount is 0.1mg to 0.4mg per 1mm, an inner diameter of the flavoring nozzle of about 0.8mm to 1.2mm (for example, about 0.9mm) may be applied for uniform flavoring, and the flavoring liquid input amount per 1mm In the case of 0.4 mg to 1.5 mg, an inner diameter of the directional 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 that are cut later and completed by the above flavoring liquid input may contain about 1 mg to 15 mg of menthol (which may vary depending on the menthol content in the flavoring liquid). Accordingly, The weight of menthol contained in the finished tube filter (for example, the support structure 130) may be greater than the weight of menthol contained in the mouthpiece part 140.

In some embodiments, the deflector nozzle 40 is disposed downstream of the steam nozzle 21 as shown, but the deflector nozzle 40 is approximately 180 mm to 600 mm from the steam nozzle 21, preferably approximately 300 mm to 600 mm (eg, about 500 mm) may be arranged to be spaced apart. That is, the distance L1 between the directional nozzle 40 and the steam nozzle 21 may be approximately 180 mm to 600 mm, preferably approximately 300 mm to 600 mm (eg, approximately 500 mm). Through this, it is possible to minimize the rate of loss of flavor occurring in 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 liquid F is simply free-falling on the upper outer surface of the tubular rod TF in this way, it is difficult to uniformly spread the fallen flavoring liquid F to the inner surface of the tubular rod TF, Furthermore, since the flavoring liquid (F) does not sufficiently permeate into the tubular rod (TF) before the subsequent process that proceeds after the flavoring treatment, the work environment is contaminated due to wetting of the filter wrapper or leakage of the flavoring liquid, 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 them to the outside of the tubular rod (TF) is performed together with the above-described flavoring treatment. As shown in FIG. 8 or 9, the air and moisture inside the tubular rod TF are discharged through the suction process, and the flavoring liquid F injected into the upper region of the tubular rod TF follows the shape of the tube. It is diffused or transferred (S) to the lower region of the tubular rod (TF), and through this, the tubular rod (TF) can be uniformly oriented.

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

Meanwhile, preferably, the flavoring liquid F is dropped by the flavoring nozzle 40 when about 60% to 90% (for example, about 70%) of the suctioning process by the suction rail has progressed. That is, the directional nozzle 40 may be disposed 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 directional nozzle 40 is approximately 300 mm to 450 mm (eg, about 350 mm) from the upstream end of the suction rail 50. spaced apart and located approximately 50 mm to 200 mm (eg, about 150 mm) from the downstream end.

In this case, the suction process before dropping the flavoring liquid transfers the tubular rod (TF) and serves to cool the tubular rod (TF) at the same time, and the suction process after dropping the flavoring liquid transfers the tubular rod (TF). It can play a role of evenly spreading the liquid into the inner region of the tubular rod (TF).

In some embodiments, the suction rail 50 may extend approximately 100 mm to 1,000 mm (L2) in the longitudinal direction of the tubular rod (TF) (ie, the traveling direction (D1) of the tubular rod (TF)), but 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 suction efficiency and flavoring liquid diffusion efficiency, the upper end 51E of the suction rail 50 may be located at the same level as or higher than the central axis TF_C of the tubular rod TF.

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

In this way, when the hollow (TF_H) of the tubular rod (TF) has a non-circular cross section, it is difficult to apply the internal flavoring method that can be considered to improve the flavoring process, and the external flavoring method of the conventional spraying method The flavoring efficiency also decreases. Unlike this method, in the case of the external flavoring method according to the present invention, regardless of whether the hollow (TF_H) of the tubular rod (TF) has a shape such as a trilobate shape or a cross shape, the tubular rod (TF) It can be flavored evenly.

On the other hand, when the hollow (TF_H) of the tubular rod (TF) has a three-lobed cross section, in order to maximize the diffusion efficiency of the flavoring liquid, any one of the three leaves (Lf1, Lf2, Lf3) of the hollow (TF_H) ( Lf1) may be aligned between the directional nozzle 40 and the central axis TF_C of 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

Using a flavoring nozzle (40, see FIG. 7) and a suction rail (50), a flavoring liquid having a menthol content of about 70% by weight was freely dropped on the outer surface of the upper side of the tubular rod, and 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. As the tubular rod moves in the traveling direction (D1), the amount of flavoring liquid injected into the tubular rod is about 0.1 mg per mm. The flavoring liquid was free-falling from the flavoring nozzle and diffused into the tubular rod.

Example 2

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

Example 3

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

Example 4

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

Experimental Example 1: Flavoring amount setting for uniform flavoring of tube filter

In order to evaluate whether the tubular rods are uniformly deflectable, the results of whether or not the tubular rods treated according to Examples 1 to 4 are uniformly deflected are shown.

division Amount of Flavor (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 Uniform Flavoring / Flavoring Liquid Flowing

As shown in Table 1, in the tubular rod of Example 1, in which the flavoring amount was 0.1 mg per 1 mm (ie, 1 mg based on one 10 mm long tube filter), the flavor was broken, and accordingly, the tubular rod was uniformly It was confirmed that it was not flavored. In the tubular rod of Example 2, the fragrance did not break, and in the tubular rod of Example 3, not only did the fragrance not break, but it was confirmed that the flavoring liquid was more uniformly treated in the tube filter. It was confirmed that the tubular rod of Example 4 was also uniformly flavored, but a phenomenon occurred in which some of the flavoring liquid that fell freely did not permeate into the tube and flowed down along the outer surface. Accordingly, in the external flavoring method, it was confirmed that the flavoring characteristics were improved when the flavoring amount of 0.3 mg to 1.2 mg per 1 mm was applied.

Example 5

A conduit is formed inside the tube filter molding rod 30, and the flavoring liquid is transported through the conduit, but the flavoring liquid is dropped from the downstream end of the tube filter molding rod 30 and delivered to the inner surface of the tube through the hollow of the tubular rod. A flavoring method was performed, and a total of 48mg of flavoring liquid having a menthol content of about 70% by weight was put into an 80mm tubular rod. The inner diameter of the flavoring nozzle of the conduit for dropping the flavoring liquid was about 1.3mm, and the flavoring nozzle was disposed about 200mm away from the steam nozzle.

The above internally flavored tubular rod 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 injected into the tubular rod, but an external flavoring method was performed in which the flavoring liquid was freely dropped on the upper outer surface of the tubular rod through the flavoring nozzle 40 and the suction treatment was performed. Flavoring was performed at the same location and the same inner diameter of the flavoring nozzle as in Example 5.

As in Example 5, the externally flavored tubular rod was stored for about 24 hours and then cut.

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 the flavoring liquid 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 degree of fragrance diffusion, the menthol content contained in the cut tube area in each of Examples 5 to 7 was analyzed and shown in Table 2.

(External incense) 53 37.0 33.4 6.3 17.3 51.8 16.1 48.2

Looking at the remaining amount in the rod compared to the amount of menthol input shown in Table 2, it can be seen that a high fragrance residual rate was found in Example 5 of the internal flavoring method and Examples 6 and 7 of the external flavoring method. The fragrance residual rate in Example 5 was about 94.6% (ie, the fragrance loss rate of about 3.6%), and the fragrance residual rate in Example 6 was about 91.4% (ie, the fragrance loss rate of about 8.6%). The fragrance residual rate in Example 7 was about 90.3% (ie, about 9.7% fragrance loss). In all of the examples, excellent fragrance residual rate characteristics of 90% or more were exhibited, especially in the case of Examples 6 and 7 of the external flavoring method, despite the high temperature and suction environment, within 5% of Examples 5 and 5% of the internal flavoring method There was only a difference in the residual rate of intention, and considering the advantages in terms of flavoring workability and economics, the advantages of applying the external flavoring method were sufficiently confirmed (however, in Examples 6 and 7 of external flavoring, internal flavoring was carried out Higher individual variation (CV) compared to Example 5 was found).

On the other hand, it was confirmed that external flavoring Examples 6 and 7 were superior to internal flavoring Example 5 in fragrance spreading characteristics. Specifically, the menthol remaining in the upper region of the tubular rod in Example 5 was about 44.5% of the total amount of menthol in the tubular rod and the menthol remaining in the lower region was about 55.5% of the total amount of menthol in the tubular rod. The menthol content in the upper region was about 52.7% and the menthol content in the lower region was about 47.3%. In Example 7, the menthol content in the upper region was about 51.8% and the menthol content in the lower region was about 48.2%. showed better fragrance spreading properties.

This is because in the case of internal flavoring, hyangaek is injected through the inner surface of the lower region of the tubular rod and diffuses upward against gravity, whereas in the case of external flavoring (and suction treatment), hyangaek is injected through the outer surface of the upper region of the tubular rod. It is expected that this is because it diffuses downward through gravity and suction force by suction treatment.

Example 8

A tubular rod was manufactured in the same manner as in Example 7, except that the directional nozzle was disposed at a position about 500 mm away 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 non-porous wrapping paper after the flavoring treatment.

Example 10

A tubular rod was prepared 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 liquid having a menthol content of about 50% by weight was used, but a total of 74mg of flavoring liquid was added to an 80mm tubular rod (ie, the amount of menthol injected was the same as in Example 8). Tubular rods were prepared in this manner.

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 non-porous wrapping paper after the flavoring treatment.

Table 3 shows the deflection conditions of the tubular rods according to Example 5 and Examples 7 to 12.

Experimental Example 3: Evaluation of flavoring method for reducing flavor loss and individual variation

In order to evaluate the loss of flavor and individual variation according to the flavoring method, the menthol content contained in the tubular rods in Example 5 and Examples 7 to 12 was analyzed and shown in Table 4.

Referring to Table 4, when other conditions are the same, it can be seen that the internal flavoring method showed a higher menthol residual rate than the external flavoring method. However, even among the examples using the same external flavoring method, It can be seen that there is a difference in the residual rate according to the flavoring conditions. In particular, the menthol residual rate of Example 9 or Example 12 in which a filter paper is applied and the flavor nozzle is separated from the steam nozzle by about 500 mm is that of Example 5 for internal flavoring. It can be seen that rather high values appeared.

Moreover, in the case of Example 9, there is a very low individual variation compared to other external flavoring examples, so when applying a filter wrapper before subsequent processes such as transfer and cutting after external flavoring, flavoring workability, economic feasibility and product uniformity It was confirmed that all castles could be secured.

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

Experimental Example 4: Evaluation of tube filter physical properties by flavoring conditions

In order to examine the change in 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 Tables 5 and 6, except for the fact that the weight of the tubular rod slightly increased according to the application of the filter wrapper, all mass production standards were met without significant differences in physical properties depending on the flavoring conditions and whether or not the filter wrapper was applied. confirmed.

Comparative Example 1

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

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

In order to confirm the menthol residual rate according to the external flavoring process conditions of the tube filter, the menthol residual rate 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 was analyzed and shown in Table 7 showed up

First, through Table 7, the degree of aroma loss according to the separation distance between the flavor nozzle and the steam nozzle can be confirmed. Referring to Examples 7 and 8, it can be seen that the menthol residual rate slightly increased in Example 8 in which the separation distance was 500 mm compared to Example 7 in which the separation distance was 200 mm. It was confirmed that there was a big difference depending on the length and the positional relationship between the suction rail and the flavoring nozzle. Specifically, as the location of the flavoring nozzle becomes farther from the downstream end of the suction rail (ie, closer to the upstream end), or as the length of the suction rail becomes longer than necessary, the menthol residual rate in the tube is noticeably lowered. You can check. This means that as the flavoring nozzle goes upstream of the suction rail, the loss of flavor due to the influence of high-temperature steam increases, and after flavoring, excessive suction process exceeds the uniform diffusion of the flavoring liquid, and some of the flavoring liquid in the tube is suctioned along with air and moisture to the outside of the tube. It is presumed to be the condensed milk discharged by However, it was confirmed that the diffusion effect of scented liquid by suction slightly decreased as the flavor nozzle got closer to the downstream end of the suction rail.

In view of the above results, the separation distance between the flavor nozzle and the steam nozzle is about 400 mm to 600 mm, the length of the suction rail is about 300 mm to 800 mm, and the flavor nozzle is about 60% of the total length of the suction rail from the upstream end of the suction rail. to 90% (eg, about 300 mm to 450 mm based on 500 mm), it was confirmed that it is advantageous in terms of the fragrance residual rate.

Comparative Example 5

For the examples, a heated cigarette having the same structure as the smoking article 200 shown in FIG. 2, which was manufactured for testing, was used. The heating cigarette included a medium unit, 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-mentioned flavoring process was not performed on the 10mm long support structure, and a 12mm long TJNS filter flavored with 6mg of menthol flavored liquid was used as the mouthpiece.

Comparative Example 6

Except for the fact that the tubular rod prepared by putting a total of 53 mg of flavoring liquid having a menthol content of about 70% by weight in the internal flavoring method described in Example 5 into an 80 mm tubular rod was cut into a length of 10 mm and used as a support structure, The same heated cigarette as in Comparative Example 5 was prepared.

Example 13

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

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

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

As shown in Table 8, Comparative Example 5 and Comparative Example 5, which were not flavored in all of Examples 13 and 14, except for the slight increase in weight and suction resistance due to the addition of flavoring liquid to the tube filter and the increase in weight due to the application of the filter wrapper. It was confirmed that it met the mass production standard without a significant difference in physical properties compared to the internally flavored cigarette of Comparative Example 6.

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

In order to confirm the transition pattern of menthol flavor during 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 the externally flavored tube filter is applied has a significantly lower rate of flavor loss over time, especially in the acebu, than the cigarette of Comparative Example 5 to which the unflavored tube filter is applied. There was no significant difference between the external flavoring and internal flavoring methods in terms of the menthol transition pattern between segments during cigarette storage. In Example 14, in which the tube is wrapped with a filter wrapper, it can be seen that it is more advantageous to reduce flavor loss during storage of cigarettes, which means that the filter wrapper reduces flavor loss in subsequent processes such as filter transfer and cutting after flavoring treatment. It is predicted that it will fulfill its role.

Experimental Example 8: Analysis of Smoke Component of Cigarette with Externally Deflecting Tube Filter

In order to analyze the smoke components of the cigarettes to which the externally directed tube filter was applied, the smoke components of the 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. Smoke collection for component analysis was repeated three times for each sample, based on 8 puffs per sample, and the component analysis results based on the average value of the three collection results are shown in Table 10. Cigarettes were tested according to Health Canada (HC) smoking conditions using an automatic smoking device in a smoking room at a temperature of approximately 20° C. and a humidity of approximately 62.5%.

As shown in Table 10, the amount of ingredients except for the menthol content did not show a significant difference in Comparative Examples 5 to 6 and Example 14, whereas the menthol delivery amount was about 38% in Example 14 compared to Comparative Example 5, Comparative In Example 6, it was confirmed that the increase was about 29%. Considering that the amount of menthol injected into the tube in Comparative Example 6 and Example 14 was the same, Example 14, in which the filter wrapper was applied after the external flavoring treatment, produced menthol through mainstream smoke. It was confirmed that it is most advantageous for maximizing the amount of fulfillment.

Example 15

For the examples, a heating cigarette composed of a medium part, a support structure, a cooling structure, and a mouthpiece, which was manufactured for testing, was used. As the support structure, the same tube filter as in Example 14 was used, and as the cooling structure, PLA woven fabric was used. That is, the heating type cigarette of Example 14 differs from the heating type cigarette of Example 14 only in that the cooling structure is a PLA woven fabric.

Example 16

The same heated cigarette as in Example 14 was manufactured, except that the paper tube was applied as the cooling structure. The inner diameter of the paper pipe was about 6 mm, and online perforation was applied to the area where the paper pipe was located, and thus the air dilution rate of the paper pipe was about 17%.

Experimental Example 9: Analysis of smoke components according to the combination of external deflecting tube filter and cooling structure

In order to confirm the difference in smoke composition according to the combination of the cooling structure of the cigarettes according to Examples 14 to 16 to which the external directing tube filter was equally applied as the support structure, the main smoke component during smoking of the 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 according to the application method of the cooling structure. Specifically, a paper pipe was applied as a cooling structure In Example 16, it can be seen that it is relatively advantageous to increase the amount of nicotine, glycerin and menthol transferred compared to Example 14 and Example 15, and this result maximizes the difference between the inner diameter of the support part and the inner diameter of the cooling part when the branch pipe is applied as the cooling structure It is expected that this is due to the improvement of thermal diffusion characteristics and the maximization of the cooling effect.

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 external directing tube filter was equally applied as the support structure, the surface temperature and the main smoke temperature during smoking of each cigarette were analyzed and shown in Table 12. Each of the surface temperature and the main smoke temperature represents the average value of the highest temperatures measured for each puff five times per sample.

Referring to Table 12, in Example 16 to which the branch pipe was applied as a cooling structure, it can be seen that the surface temperature and the main 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 Or less heat was evenly diffused to the entire cross-section in the hollow of the cooling structure, so that the concentration of melting in the center of the mouthpiece was relatively alleviated, and accordingly, it was confirmed that the amount of atomization and the amount of menthol transfer were also increased. Although not presented, in the case of the paper pipe filter application case, there was a difference in the cooling effect and sensory characteristics according to the degree of perforation of the paper pipe, that is, the air dilution rate. showed a linear increase, but when air dilution rates higher than the appropriate value were applied, issues such as wasted sucking and decreased taste intensity occurred.

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

Comparative Example 5 in which a CA tube filter with an inner diameter of 2.5 mm that is not flavored is employed as a support structure and a CA tube filter with an inner diameter of 4.2 mm is employed as a cooling structure. 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 2.5 mm in which menthol flavored liquid was externally flavored was employed as a support structure and an air dilution rate of 17 as a cooling structure. Sensory evaluation was performed on the satisfaction of suckability, menthol strength during smoking, menthol satisfaction during smoking, fragrance persistence during smoking, taste taste during smoking, and satisfaction after smoking of the cigarettes of Example 16 in which the % paper tube was employed, and the results are shown in FIG. 10. . Sensory property evaluation was conducted on a total of 61 evaluation panel members using cigarettes according to each example 4 weeks after manufacture, based on a total score of 7 points.

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

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

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