Description

Technology Field

[0001] The present invention relates to a flavor-absorbing article. Background Technology

[0002] Patent Document 1 discloses a non-combustion heating type aerosol generating article. This aerosol generating article, in other words, a flavor inhaling article, comprises a flavor element and a filter element adjacent to each other. The flavor element is formed, for example, by filling a tobacco raw material. The filter element is formed by filling a filter material, and a hollow portion is formed in the center in the diameter direction. A flavor component is deposited on the inner surface of the hollow portion. By heating the flavor element with a heater of a device (flavor inhaler), the volatilized flavor component is cooled in the filter element, thereby generating an aerosol of the flavor component, which is inhaled by a user. Prior art literature

[0003] Patent Document 1: Japanese Patent Publication No. J.T. 2020-508075 The problem to be solved

[0004] In non-combustion heating type flavor absorption articles, the heating temperature of the flavor element is lower compared to combustion heating type articles. Because of this, the flavor components volatilizing from the flavor element are reduced, and the aerosol of the flavor components generated is also reduced. The filter element described in Patent Document 1 has a hollow portion formed, and flavor components are further adsorbed on the inner surface of the hollow portion. However, since a filter material acting as a filter exists on the outer surface of the hollow portion, some of the flavor components volatilizing from the flavor element are cooled and aerosolized in the hollow portion, but the remaining flavor components may be filtered by the filter material before being aerosolized. Therefore, there is a concern that the flavor components supplied to the user may be further reduced.

[0005] Therefore, in order to aerosolize flavor components volatilized from the flavor element before filtration and supply them to the user, one might consider making the cooling segment adjacent to the flavor element a tubular element, such as a paper tube, rather than a filter element. However, since a simple paper tube merely allows volatilized flavor components to pass through along with the airflow, it is difficult to generate an aerosol, and thus it cannot provide a cooling segment suitable for non-combustion heating type flavor-absorbing articles.

[0006] The present invention has been made in consideration of these problems and aims to provide a flavor-absorbing article having a cooling segment function that replaces a filter element, which can be supplied to a user without minimizing the reduction of the flavor components of the flavor element. means of solving the problem

[0007] To achieve the above objective, a flavor-absorbing article of a certain type is a flavor-absorbing article comprising a flavor element heated by non-combustion and a tubular element forming an airflow path, wherein the tubular element comprises a hollow tube forming a cylindrical shape and a paper liner disposed within the tube along the axial direction of the tube, and the sum of the cross-sectional lengths of the liner in the tube diameter direction is greater than the inner diameter of the tube. Effects of the invention

[0008] It is possible to provide a flavor-absorbing product that has a cooling segment function replacing a filter element, while also being able to supply the flavor components of the flavor element to the user without minimizing the reduction of the flavor components.

Specific details for implementing the invention

[0010] <Flavor-absorbing items>

[0011] Hereinafter, a flavor-absorbing article (1) will be described with reference to FIGS. 1 and FIGS. 2. FIG. 1 shows a cross-sectional view of a flavor-absorbing article (1). The flavor-absorbing article (1) (hereinafter also referred to as the article) is of the non-combustion heating type and is composed of a flavor element (2), a tubular element (4), a first filter element (6), and a second filter element (8), in order from left to right as viewed in FIG. 1. The flavor element (2) is formed by filling a flavor raw material (10).

[0012] A device (flavor aspirator) used to heat a flavor element (2) is equipped with, for example, a needle-shaped heater (12). Only the heater (12) of the device is shown in FIG. 1. An article (1) is set in the device, and the heater (12) is inserted into the flavor element (2) to heat it. As a result, the flavor component impregnated in the flavor raw material (10) of the flavor element (2), or included as granules, volatilizes and vaporizes. The flavor element (2) may be a tobacco rod containing tobacco raw material as the flavor raw material (10). The tobacco raw material consists of, for example, whole tobacco or finely shredded tobacco sheets.

[0013] The first filter element (6) is a filter body filled with a filter material (14), such as acetate tow or a nonwoven sheet, and has a hollow portion (16) formed in the center in the diameter direction. The second filter element (8) is a filter body filled with a filter material (14) that is the same as the first filter element (6) or different from the first filter element (6). Each of the periphery of the flavor element (2) and the first and second filter elements (6, 8) is rolled up with a roll of paper (18).

[0014] Each element (2, 4, 6, 8) is arranged in abutment along the same axis and connected to each other by wrapping chip paper (20) around the main surface of a continuous body composed of each element (2, 4, 6, 8). A ventilation hole (22) is formed in the tubular element (4) and the chip paper (20) to draw air into the article (1) when the article (1) is sucked in. By the air introduced into the article (1) from the outside through the ventilation hole (22), the flavor components of the flavor element (2) or the volatile components of the additive described later are cooled, and the aerosolization of these components is promoted. Furthermore, the configuration of the filter element as a filter body is not limited to having the first and second filter elements (6, 8).

[0015] FIG. 2 shows a cross-sectional view of an article (1) related to a different form. The article (1) is provided with a third filter element (24) at an adjacent position opposite to the ornamental element (4) of the flavor element (2). The third filter element (24) is formed by filling a filter material (14) that is the same as, or different from, the first and second filter elements (6, 8). The third filter element (24) is positioned at a location that contacts, or can contact, the flavor material (10) of the flavor element (2), and is connected to the flavor element (2) by chip paper (20).

[0016] When the third filter element (24) is inserted through the flavor element (2) and the heater (12) is inserted, the third filter element (24) prevents the flavor ingredient (10) from flowing out from the flavor element (2) toward the source of the heater (12). That is, the third filter element (24) functions as a support segment that prevents the flavor ingredient (10) filled in the flavor element (2) in the article (1) from flowing out toward the heater (12). By doing so, it is possible to prevent the area around the source of the heater (12) of the device from becoming dirty due to the overflowing flavor ingredient (10).

[0017] The tubular element (4) is positioned adjacent to the flavor element (2) on the side opposite to the tip of the article (1) and forms an airflow path in the article (1). The tubular element (4) comprises a hollow tube (26) forming a cylindrical shape and a paper liner (28) positioned within the tube (26) along the axial direction (X) of the tube (26).

[0018] <Physiognomy Factors>

[0019] Hereinafter, the tubular element (4) of the article (1) will be described in detail with reference to FIGS. 3 to 11. FIG. 3 shows a longitudinal cross-sectional view of the tubular element (4). The liner (28) is formed by bending a single layer of paper web into an S-shape in the direction of the inner diameter (d) of the tube (26), that is, in the tube diameter direction (Y), and the cross-section of the liner (28) in the tube diameter direction (Y), that is, the longitudinal cross-section of the liner (28), forms an S-shape.

[0020] The liner (28) has a paper thickness of 0.05 mm to 1 mm, preferably 0.08 mm to 0.5 mm, more preferably 0.1 mm to 0.15 mm, and has a basis weight of 80 gsm (grams per square meter) to 120 gsm. The core tube (26) is formed as a double paper web by overlapping and bonding an inner paper web (30) and an outer paper web (32) through an adhesive portion (34). Additionally, the liner (28) may be formed as a double paper web.

[0021] The ornamental element (4) cools the flavor component volatilized from the flavor element (2) by the heat of the heater (12) to aerosolize it. The cooling and aerosolization of the flavor component is efficiently carried out by the volatilized flavor component coming into contact with the surface of the liner (28) in the space secured within the tube (26). Additionally, the liner (28) is rapidly heated by the heater (12) adjacent to the liner (28). Therefore, when a flavor agent is adsorbed onto the liner (28) as a type of additive, the flavor component volatilized from the liner (28) is efficiently cooled in the space secured within the tube (26) to become an aerosol.

[0022] The sum of the cross-sectional lengths of the liner (28) in the pipe diameter direction (Y) of the tube (26) is greater than the inner diameter (d) of the tube (26). More preferably, the sum of the cross-sectional lengths of the liner (28) in the pipe diameter direction (Y) of the tube (26) is at least twice the inner diameter (d) of the tube (26). As a result, the surface area of ​​the liner (28) is increased, so the cooling and aerosolization of the flavor components are carried out more efficiently. Thus, in the article (1), the tubular element (4) functions as a cooling segment that immediately cools and aerosolizes the flavor components volatilized from the flavor element (2) or the liner (28).

[0023] The ornamental element (4) functions as a cooling segment to promote the aerosolization of flavor components before reaching the first and second filter elements (6, 8). Because of this, the flavor components before aerosolization are inhibited from adsorbing to the fibers of the first and second filter elements (6, 8) and being filtered. Therefore, in the non-combustion heating type article (1), even if the heating temperature of the flavor element (2) is relatively low, the amount of filtration of flavor components in the first and second filter elements (6, 8) can be reduced, and the flavor components of the flavor element (2) are supplied to the user without being reduced as much as possible.

[0024] By having a liner (28) in a tubular element (4) adjacent to a flavor element (2), the liner (28) is positioned at a location that contacts the flavor ingredient (10) of the flavor element (2), or at a location where it can contact it. When a heater (12) is inserted into the flavor element (2), the liner (28) prevents the flavor ingredient (10) from flowing out from the flavor element (2) toward the tubular element (4). That is, in the article (1), the tubular element (4) functions as a support segment that supports the flavor ingredient (10) filled in the flavor element (2) so that it does not overflow.

[0025] Additives are adsorbed onto the liner (28). The additives include, for example, flavor components, activated carbon, and aerosol extenders. Since the liner (28) is made of paper, the area and surface area of ​​the additive adsorption in the liner (28) can be easily changed compared to the case where the additive is adsorbed onto the flavor raw material (10) of the flavor element (2). Because of this, the amount of additive adsorption, the amount of additive components released, and furthermore, the amount of additive components delivered to the user can be easily adjusted. That is, in the article (1), the ornamental element (4) functions as a flavor component delivery segment that enables easy control of the delivery of additives to the user, for example, the delivery of flavor components.

[0026] Both ends of the liner (28) in the pipe diameter direction (Y) are bonded to the inner surface (26a) of the branch pipe (26) by an adhesive portion (36). The adhesive portion (36) is formed by applying glue along the axis direction (X) of the liner (28) over a width of about 1 mm to 2 mm at both ends of the liner (28) and curing it. As a result, the liner (28) is fixed to the branch pipe (26), so the detachment of the liner (28) is prevented, and the buckling strength of the tubular element (4) is strengthened, thereby enhancing the function as a support segment of the tubular element (4). Additionally, the adhesive portion (36) may be formed only at one end of the liner (28) in the pipe diameter direction (Y).

[0027] FIG. 4 shows a cross-sectional view when the paper tube (26) is unfolded in the tube diameter direction (Y). The inner paper web (30) and the outer paper web (32) constitute a double paper web (27). The inner paper web (30) and the outer paper web (32) form a strip shape having approximately the same width in the unfolded width direction (Z), and have a paper thickness and basis weight in the same range as, for example, the liner (28).

[0028] The inner paper web (30) and the outer paper web (32) are positioned so as to be offset from each other in the width direction (Z), and the inner surface (32a) of the outer paper web (32) when in the tube state (26) and the outer surface (30a) of the inner paper web (30) when in the tube state form an overlapping portion (38) that partially overlaps each other.

[0029] Glue is applied to the inner edge portion (32b), which is an area other than the overlapping portion (38) of the inner surface (32a) of the outer paper web (32). The inner edge portion (32b) to which glue is applied is overlapped with the outer edge portion (30b), which is an area other than the overlapping portion (38) of the outer surface (30a) of the inner paper web (30), and the glue is cured to form a seam adhesive portion (40) (see FIG. 3).

[0030] In this way, the inner paper web (30) and the outer paper web (32) are positioned by shifting their positions in the width direction (Z), and the double paper web (27), having an overlapping portion (38), an inner edge portion (32b), and an outer edge portion (30b) formed therein, is bent and bonded to the joint bonding portion (40). As a result, as shown in FIG. 3, the paper tube (26) is formed such that the inner paper web (30) and the outer paper web (32) are bonded to the joint bonding portion (40) without any irregularities.

[0031] Accordingly, the outer surface (26b) of the tube (26) becomes a smooth surface without irregularities, and the quality of the tubular element (4) is improved. In addition, since the tube (26) is formed as a double paper web (27), compared to the case where it is formed as a single paper web, the buckling strength of the tubular element (4) is strengthened, and the function as a support segment of the tubular element (4) is strengthened.

[0032] FIG. 5 shows a longitudinal cross-sectional view of a tubular element (4) related to a different form of FIG. 3. When the width of the liner (28) in the diameter direction (Y) (width direction (Z)) is formed large, as shown in FIG. 5, the adhesive portion (36) may be formed near the curved portion forming the S-shape of the liner (28) rather than at the end of the liner (28). That is, glue can be applied along the axial direction (X) of the liner (28) to the part of the liner (28) that can contact the inner circumference (26a) of the branch tube (26).

[0033] FIG. 6 shows a longitudinal cross-sectional view of a tubular element (4) related to another form of FIG. 3, and FIG. 7 shows a cross-sectional view of the tube (26) of FIG. 6 when unfolded in the tube diameter direction (Y). As shown in FIG. 6, the tube (26) may be formed as a single-layer paper web (29). As shown in FIG. 7, the single-layer paper web (29) forms an overlapping portion (38) and a seam adhesive portion (40) by overlapping an inner edge portion (29a) to which glue is applied and an outer edge portion (29b) to which glue is not applied, as shown in FIG. 6. Although a step difference occurs in the seam adhesive portion (40), at least the liner (28) is fixed to the tube (26). Accordingly, the detachment of the liner (28) is prevented, and the buckling strength of the tubular element (4) is strengthened, and the function of the tubular element (4) as a support segment is strengthened.

[0034] FIGS. 8 to 12 schematically show the longitudinal cross-section of a tubular element (4) having a liner (28) of a shape different from that shown in FIG. 3. Additionally, each figure schematically shows the form in which the core tube (26) is formed as a single layer of paper web. FIG. 8 shows a tubular element (4) having a liner (28) in which the longitudinal cross-section forms a zigzag shape. The zigzag shape of this liner (28) is formed with approximately equal width in the tube diameter direction (Y), and the convex portion (28a) of the zigzag shape is non-contact with the inner circumference (26a) of the core tube (26).

[0035] FIG. 9 shows a longitudinal cross-sectional view of a tubular element (4) having a liner (28) forming a zigzag shape of a different type. This liner (28) is extended to a position where all convex portions (28a) forming the zigzag shape contact the inner circumferential surface (26a) of the branch pipe (26), or to a position where contact is possible. FIG. 10 shows a longitudinal cross-sectional view of a tubular element (4) having a liner (28) forming a zigzag shape of yet another type.

[0036] In this liner (28), adjacent liner parts located at the center of the zigzag shape come into contact with each other. At the center of the contact between these liner parts, other liner parts are expanded in a fan shape along the pipe diameter direction (Y), and the convex portions (28a) formed on the liner part at the center position and the expanded liner part are extended to a position where they come into contact with the inner surface (26a) of the branch pipe (26), or to a position where they can come into contact.

[0037] FIG. 11 shows a cross-sectional view of a tubular element (4) having a liner (28) whose cross-sectional surface forms a star shape. All convex portions (28a) forming the star shape of the liner (28) come into contact with or are capable of coming into contact with the inner surface (26a) of the branch pipe (26). FIG. 12 shows a cross-sectional view of a tubular element having a liner (28) composed of three independent liners (28A, 28B, 28C) whose cross-sectional surface forms a circular shape. Each liner (28A, 28B, 28C) is spaced apart from one another, but all come into contact with or are capable of coming into contact with the inner surface (26a) of the branch pipe (26).

[0038] In any of the liners (28) of FIGS. 8 to 12, the sum of the cross-sectional lengths of the liners (28) in the pipe diameter direction (Y) of the branch pipe (26), identical to the shape shown in FIG. 3, is greater than the inner diameter (d) of the branch pipe (26), and more preferably, is at least twice the size of the inner diameter (d) of the branch pipe (26). Therefore, even in the case of the liners (28) shown in FIGS. 8 to 12, the same functional effect as the S-shaped liner (28) described above is exhibited.

[0039] <Apparatus and Method for Manufacturing Ornamental Elements>

[0040] Hereinafter, with reference to FIGS. 13 and 14, a manufacturing apparatus (50) for a tubular element (4) and a method for manufacturing a tubular element (4) using the manufacturing apparatus (50) will be described. FIG. 13 shows a schematic diagram of a manufacturing apparatus (50) for a tubular element (4), and FIG. 14 shows a flowchart explaining a method for manufacturing a tubular element (4).

[0041] The manufacturing device (50) is equipped with a first paper web supply section (52), a first paper web cutting section (54), a lateral conveying section (56), a gluing section (58), a position moving section (60), a heating section (62), a tube forming section (64), a second paper web supply section (66), a second paper web cutting section (68), a liner forming section (70), a cutting section (72), etc.

[0042] When the manufacture of the ornamental element (4) begins, in the first paper web supply section (52), the first paper web (74) is drawn out from a bobbin not shown on which a paper roll is set. The first paper web (74) is guided through each roller (76) and transported along the first transport path (78) (S1: first paper web supply step). Next, in the first paper web cutting section (54), the first paper web (74) is cut along the length direction into an inner paper web (30) and an outer paper web (32) that are both strip-shaped (S2: first paper web cutting step).

[0043] Next, in the transverse return section (56), the cut inner paper web (30) and outer paper web (32) are separated from each other and returned to the first return path (78a) and the first return path (78b), respectively, which are branched from the first return path (78) (S3: transverse return step). Next, in the gluing section (58), the area that becomes the overlapping portion (38) and the inner circumference edge portion (32b) of the outer paper web (32) is glued (S4: gluing step).

[0044] Next, the inner paper web (30) and the outer paper web (32) are joined at a pair of tension rollers (80) and then returned to the first return path (78). Next, in the position change section (60), the inner paper web (30) is misaligned relative to the outer paper web (32) in a width direction that intersects with the return direction (S5: position change step). The inner paper web (30) and the outer paper web (32) are overlapped in a misaligned state to form an overlap portion (38).

[0045] Next, in the heating section (62), the glue applied to the overlapping portion (38) is cured by the heat of the heater to form an adhesive portion (34) (S6: heating step). In addition, to ensure that the glue is cured properly, a cooling step may be performed by passing through a cooling section not shown after passing through the heating section (62). Also, if the glue is cured properly, it may not be necessary to pass through the heating section (62) or the cooling section.

[0046] The inner paper web (30) and the outer paper web (32) are formed into a flat double paper web (27) that is integrated by bonding the overlapping portion (38) to the bonding portion (34), and the double paper web (27) is returned to the tube forming section (64). The manufacturing device (50) further comprises a seam gluing section (82). The seam gluing section (82) is installed between the heating section (62) and the tube forming section (64). Gluing of the inner circumference edge portion (32b) may be performed in the seam gluing section (82) instead of in the gluing section (58).

[0047] When the manufacture of the ornamental element (4) begins, the following steps S10 to S12 are carried out in parallel with the aforementioned steps S1 to S6. First, in the second paper web supply section (66), a second paper web (88) is drawn out from an unillustrated bobbin on which a paper roll is set. The second paper web (88) is guided through each roller (76) and transported along the second transport path (90) (S10: second paper web supply step).

[0048] Next, in the second paper web cutting section (68), the second paper web (88) is cut into a strip-shaped strip paper web (92) along the length direction (S11: second paper web cutting step). In the second paper web cutting step, the second paper web (66) is cut into a strip paper web (92) in which the sum of the cross-sectional lengths in the pipe diameter direction (Y) of the core tube (26) is greater than the inner diameter (d) of the core tube (26), and more preferably, the sum of the cross-sectional lengths is cut into a strip paper web (92) in which the sum of the cross-sectional lengths is more than twice the inner diameter (d) of the core tube (26).

[0049] Next, in the liner forming section (70), by applying frictional force to both ends of the strip paper web (92) in the tube diameter direction (Y), the strip paper web (92) is continuously formed into a liner (28) having an S-shaped cross-section along the length direction (S12: liner forming step). More specifically, the liner forming section (70) is equipped with a rotor tube (94) as shown in FIG. 15.

[0050] FIG. 15 shows a cross-sectional view of a rotor tube (94). The rotor tube (94) is supported by a support member (96) through a bearing (98) to rotate freely and receives a strip paper web (92) while rotating. The rotor tube (94) has an inlet section (94a) that receives the strip paper web (92), an outlet section (94b) that discharges the formed liner (28) toward the tube forming section (64), and an inner surface (94c) that gradually contracts from the inlet section (94a) toward the outlet section (94b).

[0051] In the liner forming section (70), when receiving the strip paper web (92), the ends of the strip paper web (92) come into contact with the inner surface (94c) of the inlet section (94a). As a result, frictional force acts on the ends of the strip paper web (92), and the strip paper web (92) is bent into an S-shape to form a curved section, thereby forming a liner (28) with an S-shaped cross-section.

[0052] Additionally, the entrance portion (94a) has an opening edge (94d) with an opening diameter (D) that is 30% to 80% of the paper width of the strip paper web (92). The opening edge (94d) is an area included in the inner surface (94c). By doing so, when receiving the strip paper web (92), the two end edges of the strip paper web (92) can be brought into contact with the opening edge (94d), thereby ensuring frictional force is applied to the two end edges. Thus, the strip paper web (92) can be reliably formed into an S-shaped liner (28).

[0053] Additionally, the inner surface (94c) of the rotor tube (94) is surface-treated with an arithmetic mean roughness Ra of 5μm to 30μm. This allows frictional force to be applied more effectively to the end edges when the end edges of the strip paper web (92) come into contact with the inner surface (94c) (including the opening edge (94d)) of the inlet portion (94a). Thus, the strip paper web (92) can be reliably formed into an S-shaped liner (28).

[0054] The liner molding section (70) is equipped with an additive (100) that adds an additive to the liner (28). The additive may include flavor components, activated carbon, and aerosol extenders, etc. The additive (100) adds the additive to a predetermined adsorption area and an adsorption surface area of ​​the liner (28) to adsorb the additive to the liner (28) (P1: Addition process). Additionally, the additive may be added in advance to the strip paper web (92) or the second paper web (88) before being molded into the liner (28).

[0055] In the tube forming section (64), the second conveying path (90) joins the first conveying path (78) to receive the liner (28) formed in the liner forming section (70). Next, the tube forming section (64) continuously forms the double paper web (27), which is formed by overlapping the first paper web (74), into a hollow tube (26) that continuously wraps the liner (28) and forms the double paper web (27) into a cylindrical shape. By doing so, a tubular rod (102) is formed in which the liner (28) is placed inside the tube (26) along the axial direction (X) of the tube (26) (S7: tube forming step).

[0056] Specifically, the tube forming section (64) is provided with a forming bed (104). The forming bed (104) is arranged along a first conveying path (78), and a forward section of a garnish belt (106) with an endless shape is arranged on the forming bed (104). The return section of the garnish belt (106) that has exited the forming bed (104) is guided by each roller (76) and wound onto a drive drum (108). The drive drum (108) is rotated by the driving force of an electric motor not shown. The rotation of the drive drum (108) drives the forward section of the garnish belt (106) along the first conveying direction (78).

[0057] The double paper web (27) is guided over the main path portion of the garnish belt (106) and overlapped with the garnish belt (106). A pressing member (110) is installed on the upper side of the starting portion of the molding bed (104). The pressing member (110) presses the double paper web (27) onto the bottom of the molding groove formed in the molding bed (104). As a result, the double paper web (27) travels integrally with the garnish belt (106) due to frictional force with the garnish belt (106), and the double paper web (27) is continuously molded into a U-shape and finally formed into a tube (26) that wraps the liner (28).

[0058] The tube forming section (64) is equipped with an applicator (112) for applying glue to the liner (28). The applicator (112) applies glue to both ends of the liner (28) in the tube diameter direction (Y) at least before the tubular rod (102) is formed (P2: glue application process). Additionally, the applicator (112) may apply glue only to one end of the liner (28) in the tube diameter direction (Y). Alternatively, the applicator (112) may be placed in the liner forming section (70) and glue may be applied to the liner (28) during the forming process of the liner (28). Furthermore, the glue may be applied along the axial direction (X) of the liner (28) to the portion of the liner (28) that can come into contact with the inner circumferential surface (26a) of the branch tube (26), not limited to both ends or one end of the liner (28).

[0059] The tube forming section (64) is equipped with a heater (114) that heats the glue applied to the liner (28). The heater (114) cures the glue applied to the liner (28) by heating to form the adhesive portion (34) and the seam adhesive portion (40) (P3: heating process). In addition, to ensure that the glue is cured properly, it may be passed through a cooler (not shown) after passing through the heater (114). In addition, if the glue is cured properly, the heater (114) or the cooler may not be installed.

[0060] In this way, the liner (28) is bonded to the inner surface (26a) of the branch tube (26), thereby forming a tubular rod (102) in which the branch tube (26) and the liner (28) are integrated. Next, in the cutting section (72), the tubular rod (102) is cut to a predetermined length, and a tubular element (4) is formed (S8: cutting step). By this, the manufacturing of the tubular element (4) is completed.

[0061] <Support Segment Function Test>

[0062] The graph in FIG. 16 shows the ratio of flavor raw material (10) overflowing from the flavor element (2). In Example 1, an article (1) is used in which a flavor element (2) and a tubular element (4) composed of a tube (26) and a liner (28) are connected. In Comparative Example 1, an article (1) is used in which a flavor element (2) and a tubular element (4) composed only of a tube (26) are connected. The basis weight of the paper web used in the tubular element (4) of Example 1 and Comparative Example 1 is 82 gsm. The amount of flavor raw material (10) filled into the flavor element (2) of Example 1 and Comparative Example 1 is 260 mg or more.

[0063] FIG. 17 shows a schematic diagram of a test apparatus that obtained the results of FIG. 16. The test apparatus is a device equipped with a pin-shaped heater (12), the diameter (D1) of the heater (12) is 2 mm, and the length (L) of the heater (12) is 18 mm. In this test, using this test apparatus, when the flavor element (2) of Example 1 and Comparative Example 1 is inserted into the heater (12) in the direction of the arrow, the ratio (overflow ratio) of the flavor ingredient (10) that overflows from the flavor element (2) among the flavor ingredient (10) filled in the flavor element (2) is measured.

[0064] As shown in FIG. 16, the overflow rate of Example 1 is about 4%, and the overflow rate of Comparative Example 1 is about 28%. Compared to the tubular element (4) without the liner (28) of Example 1, the supporting segment function that prevents the flavor ingredient (10) from overflowing toward the tubular element (4) is strengthened by about 7 times. From these results, it was found that the tubular element (4) with the liner (28) effectively functions as a supporting segment that suppresses the overflow of the flavor ingredient (10) when the heater (12) is inserted into the flavor element (2).

[0065] <Buckling Strength Test of Tubular Elements>

[0066] The graph in FIG. 18 shows the maximum load until buckling occurs when the tubular element (4) is compressed along its axis. In Example 1, a tubular element (4) composed of a core tube (26) and a liner (28) (without the adhesive portion (36) of the liner (28)) is used. In Example 2, a tubular element (4) composed of a core tube (26) and a liner (28) (with the adhesive portion (36) of the liner (28)) is used. In Comparative Example 1, a tubular element (4) composed only of a core tube (26) (single-layer paper web) is used. In Comparative Example 2, a tubular element (4) composed only of a core tube (26) (double-layer paper web) is used. The paper thickness of the paper web used for the tubular element (4) in each example and each comparative example is 0.1 mm to 0.13 mm, and the basis weight is 82 gsm to 100 gsm. The same applies to each subsequent test.

[0067] FIG. 19 is a schematic diagram of a test apparatus that obtained the results of FIG. 18. The test apparatus is equipped with a cylindrical pusher (116), and the diameter (D2) of the pusher (116) is 15 mm, which is larger than the diameter of the tubular element (4). In this test, the test apparatus is used to lower the pusher (116) in the direction of the arrow to press one end of the tubular element (4) installed in the axial direction (X), and the maximum load until the tubular element (4) buckles is measured. By doing so, the buckling strength of the entire tubular element (4) is measured. In addition, the lowering speed of the pusher (116) is 20 mm / min, and the lowering distance of the pusher (116) from one end of the tubular element (4) is 2 mm.

[0068] As shown in FIG. 18, the maximum load of Example 1 is about 68 N, and the maximum load of Example 2 is about 61 N. Meanwhile, the maximum load of Comparative Example 1 is about 23 N, and the maximum load of Comparative Example 2 is about 38 N. As is evident from the results of Examples 1 and 2, the buckling strength of the tubular element (4) is slightly greater when the liner (28) is not attached to the inner circumference (26a) of the branch pipe (26). This is because when the liner (28) is not attached to the branch pipe (26), displacement of the liner (28) relative to the branch pipe (26) is allowed when compressed, and the branch pipe (26) and the liner (28) individually generate a reaction force resisting the compressive force, and as a result, the compressive force is dispersed.

[0069] As is evident from the results of Comparative Examples 1 and 2, by configuring the core tube (26) as a double paper web (27) in which the inner and outer paper webs (30, 32) overlap, the buckling strength of the tubular element (4) is strengthened by approximately 1.7 times. The tubular element (4) having the liner (28) of Example 1 has a buckling strength of approximately 3 times compared to the tubular element (4) consisting only of the core tube (26) of Comparative Example 1. Furthermore, the tubular element (4) having the liner (28) of Example 1 has a buckling strength of approximately 1.8 times compared to the tubular element (4) consisting only of the core tube (26) of the double paper web (27) of Comparative Example 2.

[0070] There is concern that the article (1) may buckle in the tubular element (4) due to the insertion resistance when the flavor element (2) is inserted into the heater (12) of the device. However, from the above results, it was found that the buckling strength of the tubular element (4) is greatly strengthened by installing a liner (28) having a curved portion in the tubular element (4). In addition, it was found that the buckling strength of the tubular element (4) is further strengthened by configuring the core tube (26) as a double paper web (27).

[0071] <Buckling Strength Test of Liner>

[0072] The graph in FIG. 20 shows the maximum load until buckling occurs when the liner (28) is compressed in its axis direction (X). In Example 1, a tubular element (4) composed of a core tube (26) and a liner (28) without an adhesive portion (36) is used. In Example 2, a tubular element (4) composed of a core tube (26) and a liner (28) with an adhesive portion (36) is used. In Comparative Example 1, a tubular element (4) composed of a core tube (26) and a non-curved strip-shaped liner (28) is used. In Example 3, a tubular element (4) composed of a core tube (26) and a liner (28) made of a double paper web is used.

[0073] FIG. 21 is a schematic diagram of a test apparatus that obtained the results of FIG. 20. The test apparatus is equipped with a cylindrical pusher (116), and the diameter (D3) of the pusher (116) is 5 mm, which is smaller than the diameter of the tubular element (4). In this test, the test apparatus is used to lower the pusher (116) in the direction of the arrow to press one end of the tubular element (4) installed in the axial direction (X), and the maximum load (buckling strength) until the tubular element (4) buckles is measured. In addition, the lowering speed of the pusher (116) is 20 mm / min, and the lowering distance of the pusher (116) from one end of the tubular element (4) is 2 mm.

[0074] As shown in FIG. 20, the maximum load of Example 1 is about 4.6 N, the maximum load of Example 2 is about 4.9 N, and the maximum load of Example 3 is about 8.2 N. Meanwhile, the maximum load of Comparative Example 1 is about 0.8 N. As is evident from the results of Examples 1 and 2, the buckling strength of the liner (28) increases when the liner (28) is attached to the inner circumferential surface (26a) of the branch pipe (26). This is because when the liner (28) is attached to the branch pipe (26), the compressive force applied to the liner (28) is also distributed to the branch pipe (26).

[0075] As is evident from the results of Examples 1 and 2 and Comparative Example 1, by forming the liner (28) in an S-shape, the buckling strength of the liner (28) is strengthened by about 5.7 to about 6.1 times compared to the case where the liner (28) is formed in a strip shape without a curve. The liner (28) made of a double paper web (27) of Example 3 has a buckling strength of about 1.8 times stronger than the liner (28) made of a single paper web of Example 1.

[0076] There is concern that the article (1) may buckle in the liner (28) of the tubular element (4) due to the insertion resistance when the flavor element (2) is inserted into the heater (12) of the device. However, from the above results, it was found that the buckling strength of the liner (28) is greatly enhanced by installing a liner (28) having a curved portion in the tubular element (4). In addition, it was found that the buckling strength of the liner (28) is further enhanced by forming an adhesive portion (36) in the liner (28) and by configuring the liner (28) as a double paper web.

[0077] <Product Temperature Measurement Test>

[0078] FIG. 22 shows a schematic diagram of a test apparatus for a temperature measurement test of an article (1), and the graph in FIG. 23 shows the time-series temperature change of the measurement points (P1, P2, P3) of FIG. 22. The test apparatus heats the main surface of the flavor element (2) of the article (1) shown in FIG. 1 with a heater (118) and measures the temperature of the measurement point (P1) located near the flavor element (2) in the ornamental element (4), the measurement point (P2) located at the center of the axial direction of the ornamental element (4), and the measurement point (P3) located near the first filter element (6) in the ornamental element (4), respectively.

[0079] As shown in FIG. 23, about 40 seconds after the start of the test, the measurement point (P1) is about 145°C, the measurement point (P2) is about 90°C, and the measurement point (P3) is about 50°C. About 180 seconds after the start of the test, the measurement point (P1) is about 145°C, the measurement point (P2) is about 65°C, and the measurement point (P3) is about 42°C. About 240 seconds after the start of the test, the measurement point (P1) is about 140°C, the measurement point (P2) is about 60°C, and the measurement point (P3) is about 40°C.

[0080] At the measurement point (P1), the temperature rises rapidly initially compared to measurement points (P2, P3) at the point closest to the heater (118), and remains at a high temperature for a long time overall. Although the temperature at each measurement point (P1~P3) is hunting, the hunting at measurement point (P1) is smoother compared to measurement points (P2, P3). From these results, it was found that when an additive is applied to the liner (28) of the ornamental element (4), if an area of ​​the additive is formed at the location closest to the heater (118), that is, at the location of the liner (28) adjacent to the flavor element (2) near the flavor element (2), the volatilization and subsequent aerosolization of the additive can be continuously promoted because the area of ​​the additive is maintained at a relatively high temperature from the initial stage.

[0081] <Flavor Component Delivery Test>

[0082] FIG. 24 shows a cross-sectional view of each article (1) used in comparative examples and embodiments of the flavor component delivery test. In this test, while heating the main surface of the flavor element (2) of each article (1) of a different shape with a heater (118), the end surface of the first filter element (6) or the second filter element (8) is puffed, and the amount of flavor component delivered from the end surface to the outside of the article (1) is measured.

[0083] The article (1) of Comparative Example 1 is composed of a flavor element (2) (tobacco rod) containing a flavor component, an ornamental element (4) composed only of a tube (26), a first filter element (6), and a second filter element (8) that has absorbed the flavor component. The article (1) of Comparative Example 2 is composed of a flavor element (2) (tobacco rod), an ornamental element (4) composed only of a tube (26), a first filter element (6), and a second filter element (8) that has absorbed the flavor component.

[0084] The article (1) of Comparative Example 3 is composed of a flavor element (2) (tobacco rod), a tubular element (4) composed only of a core tube (26), and a first filter element (6) that has absorbed a flavor component. The article (1) of Example 1 is composed of a flavor element (2) (tobacco rod), a tubular element (4) composed of a core tube (26) and a liner (28) that has absorbed a flavor component in a folded shape, and a first filter element (6) that has absorbed a flavor component. The article (1) of Example 2 is composed of a flavor element (2) (tobacco rod), a tubular element (4) composed of a core tube (26) and a liner (28) that has absorbed a flavor component in an S-shape, and a first filter element (6) that has absorbed a flavor component. Additionally, menthol is used as the flavor component absorbed.

[0085] The graph in FIG. 25 shows the amount of flavor component delivered per puff of each item (1) in FIG. 24 in a time series. The broken line located at the top of the graph shown in FIG. 25 represents the temperature of the heater (118), and the temperature scale is indicated on the vertical axis on the right side of the graph. The item (1) of Example 2 delivers the largest amount of flavor component, approximately 0.57 mg / stk, in the first puff. In addition, "stk" constituting the unit means one stroke of the suction operation of the item (1), that is, one puff.

[0086] In addition, the article (1) of Example 2 delivers at least 0.1 mg / stk of flavor components from the beginning of the puff to the end of the puff. Although the amount of flavor components delivered in the first puff of the article (1) of Example 1 is slightly less than that of the article (1) of Example 2, the change in the amount of flavor components delivered with increasing puff frequency is almost the same as that of the article (1) of Example 2.

[0087] FIG. 26 shows an image of the ornamental element (4) of Example 2. In Example 2, as illustrated, when the flavor component (120) is attached to a location near the flavor element (2) of the liner (28), the heat from the heater (118) heating the flavor element (2) is easily transferred to the flavor component (120). Because of this, as shown in FIG. 26, the flavor component (120) volatilizes early to become an aerosol (122), and a large amount of flavor component (120) can be supplied to the user during the initial puffing stage.

[0088] In addition, since the liner (28) of Example 2 has a simple S-shape, compared to the folded liner (28) of Example 1, a wider space is secured within the tube (26), and the air permeability of the tube (26) is increased. As the air permeability of the tube (26) increases, the volatilization and aerosolization of the volatilized flavor component (120) are promoted, so the amount of flavor component delivered in the first puff is slightly greater in Example 2 than in Example 1.

[0089] FIG. 27 shows an image of the flavor element (2) of Comparative Example 1. In Comparative Example 1, the flavor element (2) is in a dense state because the tobacco raw material (124) filled around the flavor component (120) is present, and the air permeability within the flavor element (2) is reduced. In Comparative Example 1, due to the reduced air permeability, the volatilization and aerosolization of the flavor component (120) are delayed in the initial stage of the puff, and the amount of flavor component delivered in the first puff is about 0.35 mg / stk, which is about 60% of that of Example 2.

[0090] However, in Comparative Example 1, as time passes and the number of puffs increases, the flavor element (2) is heated by the heater (118) and its temperature gradually rises, thereby gradually promoting the volatilization and aerosolization of the flavor component (120) in the flavor element (2). Additionally, the volatilization and aerosolization of the flavor component adsorbed on the second filter element (8) are also promoted by the heated airflow. Therefore, the amount of flavor component delivered around the 8th to 11th puff is greater than in the case of Examples 1 and 2.

[0091] In Comparative Examples 2 and 3, flavor components are contained only in the first filter element (6) or the second filter element (8) separated from the flavor element (2). Because of this, time is required until the airflow is heated by the heater (118). In addition, there is a drawback that flavor components are filtered in the first filter element (6) or the second filter element (8). Therefore, in the case of Comparative Examples 2 and 3, the amount of flavor components volatilized is small, and the amount of flavor components delivered remains small even as time passes and the number of puffs increases.

[0092] From these results, it is preferable to add and absorb the flavor component to the liner (28) of the ornamental element (4) adjacent to the flavor element (2), rather than adding and absorbing it only to the flavor element (2) which is the direct heating target of the heater (118). In addition, it is preferable to add and absorb it to the liner (28) of the ornamental element (4) adjacent to the flavor element (2), rather than adding and absorbing it only to the first filter element (6) or the second filter element (8) separated from the flavor element (2). By doing so, the flavor component can be supplied to the user in greater quantities and more efficiently.

[0093] As described above, the article (1) of the embodiment comprises a flavor element (2) heated by non-combustion and a tubular element (4) forming an airflow path, and the tubular element (4) comprises a hollow paper tube (26) forming a cylindrical shape and a paper liner (28) disposed within the paper tube (26) along the axial direction (X) of the paper tube (26), and the sum of the cross-sectional lengths of the liner (28) is greater than the inner diameter (d) of the paper tube (26).

[0094] Accordingly, the flavor components volatilized from the flavor element (2) can be provided to the user without minimizing the reduction of flavor components by means of a liner (28) that does not have a filtration function. Additionally, because the sum of the cross-sectional lengths of the liner (28) is greater than the inner diameter (d) of the tube (26), a curved portion is formed in the liner (28), and the surface area of ​​the liner (28) can be secured significantly. Therefore, a cooling segment function can be realized, which instantly cools and aerosolizes the flavor components volatilized from the flavor element (2) on the surface of the liner (28).

[0095] Additionally, when the ornamental element (4) is placed adjacent to the flavor element (2), a support segment function can be realized to suppress the overflow of the flavor raw material (10) filled in the flavor element (2) by the liner (28). Furthermore, additives, specifically flavor components, activated carbon, and aerosol extenders, may be adsorbed onto the liner (28). In this case, the adsorption of additives onto the liner (28) is easy, and by changing the adsorption area and adsorption surface area of ​​the additives on the liner (28), a flavor component delivery segment function can be realized, which allows for easy control of the delivery of additives to the user, such as the delivery of flavor components.

[0096] Additionally, the portion of the liner (28) that can contact the inner surface (26a) of the branch pipe (26) is bonded to the inner surface (26a) of the branch pipe (26) along the axial direction (X) of the liner (28). As a result, since the liner (28) is fixed to the branch pipe (26), the detachment of the liner (28) is prevented, and the buckling strength of the tubular element (4) is strengthened, thereby enhancing the function as a support segment of the tubular element (4).

[0097] In addition, the paper thickness of the liner (28) is 0.05 mm to 1 mm, and the basis weight of the liner (28) is 80 gsm to 120 gsm. By doing so, the buckling strength of the liner (28) is enhanced, and the function as a support segment for the liner (28) and furthermore the tubular element (4) is enhanced. In addition, the paper thickness and basis weight may be achieved by forming the liner (28) as a double paper web.

[0098] In addition, the sum of the cross-sectional lengths of the liner (28) in the pipe diameter direction (Y) is greater than twice the inner diameter (d) of the branch pipe (26). As a result, the surface area of ​​the liner (28) is further increased, thereby further enhancing the functions of the aforementioned cooling segment, support segment, and flavor component delivery segment.

[0099] In addition, the cross-section of the liner (28) in the pipe diameter direction (Y) forms a continuous S-shape, and since it has a simple shape, the manufacturing of the liner (28) becomes easy. Also, because it has a simple shape, the airflow path within the branch tube (26) can be fully utilized as a space for volatilization and aerosolization of flavor components, etc., and the various effects described above can be obtained.

[0100] The description of the embodiments is concluded above, but the above embodiments are not limited and various modifications are possible within the scope of not deviating from the intent. For example, in the liner forming step, the means for applying frictional force to both ends of the strip paper web (92) is not limited to the form using the aforementioned rotor tube (94).

[0101] In addition, the composition of the article (1) and the position of the ornamental element (4) in the article (1) are not limited to the shapes described above. However, as described above, it is preferable to place the ornamental element (4) in an adjacent position to the flavor element (2) to be heated. In addition, the article (1) does not necessarily have to be equipped with a filter element, and the flavor element (2) does not have to contain tobacco raw materials. In addition, the shape of the liner (28) is not limited to the S-shape and the shapes shown above, provided that the conditions described above are satisfied.

[0102] In addition, as is evident from the results of the <buckling strength test of the tubular element> and the <buckling strength test of the liner>, if you want to strengthen the buckling strength of the tubular element (4), the tube (26) of the tubular element (4) may be formed as a double paper web (27), and the liner (28) may be formed as a double paper web. In addition, as is evident from the results of the <flavor component delivery test>, it is preferable to add and adsorb an additive containing flavor components such as a flavor agent to the liner (28) of the tubular element (4) adjacent to the flavor element (2) to be heated. However, the tubular element (4) does not necessarily have to be placed adjacent to the flavor element (2), and it is sufficient if it is placed in a relatively close position.

[0103] In addition, as determined from the results of the <temperature measurement test of the article>, in order to promote the volatilization and further aerosolization of the additive, the area in which the additive is adsorbed on the liner (28) is preferably a location that is as close as possible to the flavor element (2) and becomes high temperature, that is, the side of the flavor element (2), or one end of the liner (28) that can come into contact with the flavor element (2). However, it is not limited to this, and the adsorption area and adsorption surface area of ​​the additive in the liner (28) can be changed in various ways depending on the specifications of the article (1).
