FIG. 1 is a perspective view of an aerosol-generating article 100 according to an embodiment, and FIG. 2 is an exploded view of an aerosol-generating article 100 according to an embodiment.

Referring to Figures 1 and 2, an aerosol-generating article 100 according to one embodiment may include a medium segment 110 and a filter segment 120 connected to the downstream side of the medium segment 110.

Additionally, the aerosol-generating article 100 may further include a tip paper 130 capable of wrapping at least a portion of the medium segment 110 and the filter segment 120. For example, the tip paper 130 may surround the entire filter segment 120 and a portion of the medium segment 110 in the longitudinal direction of the filter segment 120, so that the filter segment 120 and the medium segment 110 It can wrap the connected connection part 140.

The medium segment 110 may include a sheath 111 containing tobacco material and a sheath wrapper 112 surrounding the sheath 111.

For example, the tobacco material may include cut filler as well as at least one component of leaf tobacco, granular tobacco (tobacco granules), reconstituted tobacco, or slurry tobacco. Alternatively, the medium segment 110 may include functional substances (eg, taurine, caffeine, red ginseng ingredients, medicinal ingredients, etc.) as the medium instead of the tobacco material.

Additionally, the media segment 110 may include an aerosol-generating material such as glycerin. Additionally, media segments 110 may contain other additives such as flavorants, humectants, and/or organic acids. In addition, a flavoring liquid such as menthol or a moisturizer may be added to the medium segment 110. For example, the flavoring liquid may be added by spraying the medium segment 110.

The filter segment 120 may include a filter 121 and a filter wrapper 122 surrounding the filter 121. For example, filter segment 120 may be a cellulose acetate filter. Additionally, the filter segment 120 may be made of a paper filter or a porous molded material. Additionally, filter segment 120 may be colored or flavored.

Figure 3 is a tip paper 130 of an aerosol-generating article 100 according to one embodiment.

Referring to FIG. 3, the tip paper 130 shown in an unfolded form in FIG. 2 is shown in an unfolded state in FIG. 3.

The tip paper 130 of the aerosol-generating article 100 according to one embodiment may include an adhesive area 133 to which adhesive may be partially applied. As will be described later, when the tip paper 130 wraps the media segment 110 and the filter segment 120, the adhesive area 133 may be positioned around the connecting portion 140.

As described above, the tip paper 130 may include an adhesive area 133 to be adhered to the media segment 110 and the filter segment 120, and the adhesive area 133 is located around the connection portion 140. It can be positioned and attached while firmly connecting the medium segment 110 and the filter segment 120.

The adhesive area 133 may be formed in various patterns. For example, the adhesive area 133 is a longitudinal adhesive application area 1331 directed from the first end 131 of the upstream tip paper 130 to the second end 132 of the downstream tip paper 130. It may include a longitudinal adhesive-free area ( 1332).

In one embodiment, the longitudinal adhesive application area 1331 and the longitudinal adhesive non-application area 1332 are connected to the tip paper 130 when the tip paper 130 surrounds the medium segment 110 and the filter segment 120. ) may be arranged alternately along the circumferential direction (e.g., a direction perpendicular to the longitudinal direction). For example, a longitudinal adhesive application area 1331 is disposed along the circumferential direction of the tip paper 130, a longitudinal adhesive non-application area 1332 is disposed adjacent to it, and a longitudinal adhesive application area 1332 is disposed adjacent to it again ( 1331) may be disposed, followed by a longitudinal adhesive-free area 1332. In this way, a longitudinal adhesive non-application area 1332 may be located between the longitudinal adhesive application areas 1331. In this form, the longitudinal adhesive-free areas 1332 may be disposed at equal intervals along the circumference of the tip paper 132.

In one embodiment, no adhesive is applied to the longitudinal adhesive-free area 1332, so that between the longitudinal adhesive-free area 1332 and the media segment 110, or between the longitudinal adhesive-free area 1332 and the filter. A space through which air can flow may be formed between the segments 120. Conversely, since adhesive is applied to the longitudinal adhesive application area 1331, air is not present between the longitudinal adhesive application area 1331 and the medium segment 110, or between the longitudinal adhesive application area 1331 and the filter segment 120. difficult to enter. Instead, stable coupling of the medium segment 110 and the filter segment 120 is possible through the longitudinal adhesive application area 1331.

The longitudinal adhesive-free area 1332 allows the inflow of external air, and the external air introduced in this way mainly serves to dilute the aerosol component generated in the medium segment 110. Additionally, by lowering the temperature of the aerosol generated in the medium segment 110, the heat of the aerosol when inhaled can be reduced.

In one embodiment, the length or thickness of the adhesive application areas 1331 and 1332 may have various values. These values will be explained after explaining the tip paper of the aerosol-generating article according to another embodiment.

Figure 4 is another form of the tip paper 230 of an aerosol-generating article according to an embodiment, and Figure 5 is another form of the tip paper 330 of an aerosol-generating article according to an embodiment.

Unless otherwise stated, the aerosol-generating article according to one embodiment will be described on the premise that the component(s) and their sub-component(s) having the same reference numerals have the same structure, function, effect, etc.

Referring to FIG. 4 , the adhesive area may further include a circumferential adhesive application area 1333 in which adhesive is applied along the circumference of the tip paper 230 . The circumferential adhesive application area 1333 may be formed closer to the second end 132 of the tip paper 130 than the first end 131.

In one embodiment, the circumferential adhesive application area 1333 may be located on the downstream side of the tip paper 132 and formed along the circumferential direction of the tip paper 132, and may be formed along the circumferential adhesive application area 1333. As the adhesive is applied, an air-permeable space is not formed between the circumferential adhesive application area 1333 and the filter segment 120.

Due to the circumferential adhesive application area 1333, the longitudinal adhesive non-application area 1332 does not extend to the second end 132 of the tip paper 130. That is, the longitudinal adhesive non-application area 1332 may extend from the first end 131 of the tip paper 130 to the central portion of the tip paper 130 where the circumferential adhesive application area 1333 is formed.

Due to the circumferential adhesive application area 1333, it is difficult for external air introduced through the longitudinal adhesive non-application area 1332 to escape through the second end 132 of the tip paper 130. Therefore, according to the embodiment of FIG. 4 , compared to the embodiment of FIG. 3 , external air flowing into the longitudinal adhesive-free area 1332 can be smoothly guided to the filter segment 120. This allows the aerosol components generated in the medium segment 110 to be more effectively diluted and the temperature of the aerosol to be efficiently reduced.

Referring to Figure 5, the adhesive area of the tip paper 330 of the aerosol-generating article according to one embodiment is the circumference of the tip paper 330 between the longitudinal adhesive application area 1331 and the circumferential adhesive application area 1333. It may include a circumferential adhesive non-application area 1334 along which adhesive is not applied.

For example, the circumferential adhesive-free area 1334 is formed along the circumference of the tip paper 130 excluding the edge of the tip paper 130 (e.g., the bottom and top of the tip paper 130 in Figure 5). It can be.

Due to the circumferential adhesive-free area 1334, the external air introduced through the longitudinal adhesive-free area 1332 flows smoothly into the middle portion of the tip paper 130 and then flows in the circumferential direction of the tip paper 130. Accordingly, it can be uniformly guided to the filter segment 120. Therefore, according to the embodiment of FIG. 5, compared to the embodiment of FIG. 3 or the embodiment of FIG. 4, the outside air flowing into the longitudinal adhesive non-application area 1332 is uniformly distributed along the circumference of the filter segment 120. It can be smoothly guided to the filter segment 120 in a diffused state. This allows the aerosol components generated in the medium segment 110 to be diluted more uniformly and the temperature of the aerosol to be reduced more quickly.

FIG. 6 shows a state in which the tip paper 130 according to the embodiment of FIG. 3 is unfolded in the aerosol-generating article 100 according to one embodiment, and FIG. 7 shows the aerosol-generating article 100 according to the embodiment of FIG. 6. This is also the state of use.

As described above, the adhesive area 133 may be positioned around the connecting portion 140 of the filter segment 120 and the media segment 110, and in particular the longitudinal adhesive application area 1331 may be positioned around the connecting portion 140. Can be located around. External air may be introduced into the filter segment 120 through an opening 134 capable of introducing air formed at the first end 131 of the tip paper 130 where the longitudinal adhesive-free area 1332 is disposed. .

Since the adhesive area 133 includes the longitudinal adhesive application area 1331, the filter segment 120 and the medium segment 110 can be adhered and fixed.

Since external air may be introduced through the opening 134 of the longitudinal adhesive non-application area 1332, the aerosol-generating article 100 according to one embodiment includes a separate device for introducing air into the filter segment 120. The process of providing perforation is unnecessary.

Referring again to FIGS. 3 to 5, in one embodiment, the longitudinal length (a) of the tip paper of the longitudinal adhesive application area 1331 may be 8 mm or more, and the circumferential length (b) may be 2 mm or more. You can. Additionally, the ratio of the total length of the longitudinal adhesive application area 1331 in the circumferential direction to the circumferential length c of the tip paper 130 may be 40 to 70%. This numerical range will be explained in more detail below.

division Adhesion area Filter connection air dilution a 8mm or more Good connection (no breakage) -(no effect) b 2mm or more Good connection (no breakage) -(no effect) c 40~70% Good connection (no breakage) Good

division Adhesion area Filter connection air dilution a less than 8mm Poor connection (broken, spigot missing) -(no effect) b less than 2mm Poor connection (tip paper bursting) -(no effect) c less than 40% Poor connection (causing breakage) Good 70&exceed Good connection (no breakage) error

[Table 1] and [Table 2] show the length (a) of the longitudinal adhesive application area 1331 or the longitudinal adhesive non-application area 1332 of the tip paper 130 according to an embodiment, and the longitudinal adhesive application area It represents the circumferential length (b) of (1331) and the ratio (c) of the circumferential length of the longitudinal adhesive application area 1331 to the circumferential length of the tip paper 130 (c), according to each value. It shows the relationship between filter connection and air dilution.

Referring to [Table 1] and [Table 2], when the length (a) of the longitudinal adhesive application area 1331 or the longitudinal adhesive non-application area 1332 is 8 mm or more, the filter segment 120 and the medium segment ( Although the connection of 110) is good, if the length (a) of the longitudinal adhesive application area 1331 or the longitudinal adhesive non-application area 1332 is less than 8 mm, the connection between the filter segment 120 and the medium segment 110 is poor. It can be seen that due to the defect, the aerosol-generating article 100 is broken or the medium (eg, tobacco material) in the medium segment 110 is missing.

In addition, when the circumferential length (b) of the longitudinal adhesive application area 1331 is 2 mm or more, the connection between the filter segment 120 and the medium segment 110 is good, but the circumferential direction of the longitudinal adhesive application area 1331 is good. When the length (b) was less than 2 mm, the tip paper 130 bursting occurred.

In addition, when the ratio (c) of the circumferential length of the longitudinal adhesive application area 1331 to the circumferential length of the tip paper 130 is 40% or more and 70% or less, the filter segment 120 and the medium segment Although the connection of (110) was good and air dilution was good, if the ratio (c) of the circumferential length of the longitudinal adhesive application area 1331 to the circumferential length of the tip paper 130 (c) was less than 40%. Although the degree of air dilution was good, the connection between the filter segment 120 and the medium segment 110 was poor, and the ratio of the circumferential length of the longitudinal adhesive application area 1331 to the circumferential length of the tip paper 130 When (c) exceeds 70%, the connection between the filter segment 120 and the medium segment 110 was good, but the degree of air dilution was poor.

In order to ensure a good connection between the media segment 110 and the filter segment 120 by the adhesive area 133 of the tip paper 130 of the aerosol-generating article 100 according to one embodiment, a longitudinal adhesive application area is provided. The longitudinal length (a) of the tip paper of 1331 is at least 8 mm, and the circumferential length (b) is at least 2 mm. At this time, when the ratio of the total length along the circumferential direction of the longitudinal adhesive application area 1331 to the circumferential length c of the tip paper 130 is 40 to 70%, the connection portion (e.g., the connection portion in FIG. 7) Since an opening (e.g., opening 134 in FIG. 7) can be sufficiently formed around (140)), dilution due to the inflow of external air can be good.
