Patent Document 1: Japanese Patent No. 6227555

Flavor source-containing rods such as tobacco rods require channels as air flow paths, but in order to obtain a satisfactory flavor, it is preferable that a plurality of channels with relatively small diameters exist. If a channel with a large diameter is formed carelessly, a satisfactory flavor cannot be obtained, so it is necessary to avoid forming unnecessary channels. Non-combustion heating type flavor intake articles include an internal heating type in which a heater is inserted into the tobacco rod to heat it, and an external heating type in which a heater is placed around the tobacco rod to heat it. In the case of the internal heating type, from the viewpoint of usability, it is necessary for the heater to be easily inserted into the cap member provided at the tip of the tobacco rod. Additionally, it is necessary to avoid the formation of unnecessary channels within the tobacco rod due to insertion of the heater. In addition, in the case of the external heating type, the tobacco rod may be deformed when the heater disposed around touches it. However, from the viewpoint of obtaining a satisfactory flavor, it is necessary to avoid forming unnecessary channels at this time. . In relation to these points, there is room for improvement in conventional non-combustion heating type flavor absorption articles. In view of these circumstances, the object of the present invention is to provide a flavor source-containing rod provided with a cap member at the tip that can provide excellent usability and flavor.

The inventors have discovered that a cap member having relatively small diameter channels and not containing excessively large diameter channels solves the above problems. That is, the above problem is solved by the following present invention.

Figure 1a shows one embodiment of a non-combustion heating type flavor aspiration device. In the figure, 100 is a non-combustible heating type flavor aspiration device, 1 is a flavor source-containing rod, 3 is a first mouthpiece segment, 5 is a second mouthpiece segment, and 7 is a third mouthpiece segment. Hereinafter, each segment will be described with reference to the drawings.

1. Load containing flavoring agents

The flavor source-containing rod has a cap member 11 at the tip opposite to the mouth end, and a flavor source filling 13 downstream thereof.

(1) Cap member

The cap member 11 includes a sheet containing natural fibers, and the sheet is arranged so that its main surface is substantially parallel to the longitudinal direction of the flavor source-containing rod. That is, the normal line of the main surface of the sheet is perpendicular to the longitudinal direction (axial direction) of the flavor source-containing rod. Figure 2 shows a conceptual diagram of the corresponding sun. By arranging the sheet so that the main surface of the sheet is approximately parallel to the longitudinal direction of the flavor source-containing rod, an appropriate channel is formed, and an excellent feeling of use and flavor can be obtained. Additionally, the heater can be easily inserted by arranging the sheet as described above. The cap member 11 may be provided with a wrapper and the sheet may be filled in the wrapper (FIG. 2), or may be formed by, for example, adhering the sheets to each other without using a wrapper. From the viewpoint of ease of manufacture, the former mode is preferable.

The axial length of the cap member 11 is preferably 6 to 20 mm, more preferably 6 to 10 mm. The outer circumference (circumference) may be 15 to 30 mm. By having an axial length in this range, mass production of cap members becomes possible. Additionally, if the axial length is less than the lower limit, components volatilized from the flavor source filling are not trapped and leak to the outside, which may cause a defect such that the device becomes dirty. If the axial length is too long, the ventilation resistance of the cap member itself increases, which increases the ventilation resistance of the entire non-combustion heating type flavor suction device, making it difficult to inhale during use.

In addition to the upstream end of the flavor source-containing rod 1, the cap member 11 may be further disposed at the downstream end of the flavor source-containing rod 1. The axial direction of the cap member 11 refers to a direction parallel to the longitudinal direction (axial direction) of the flavor source-containing rod when assembled as a flavor source-containing rod, and is the horizontal direction in FIG. 1. By further disposing the cap member 11 at the downstream end of the flavor source-containing rod 1, it is possible to prevent the flavor source filling from overflowing toward the mouthpiece segment during transportation. Additionally, in the case of the internal heating type, it is possible to prevent the flavor source filling from overflowing toward the mouthpiece segment when the heater is inserted inside the rod.

(1-1) Sheet

The natural fiber-containing sheet 12 is preferably a sheet capable of forming a cap member that has channels of relatively small diameter and does not contain channels of excessively large diameter. Specifically, the natural fiber-containing sheet 12 may be a woven fabric, a non-woven fabric, or a sheet containing a polymer matrix and the fibers. Woven fabrics are fabrics made by processing fibers such as cotton or silk into threads. The thickness of the woven fabric is preferably 0.5 to 1.5 mm. Non-woven fabric is made by bonding or entangling fibers rather than weaving them to form a sheet. Nonwoven fabrics are roughly divided into wet-laid nonwoven fabrics, which are manufactured from fibers dispersed in a liquid medium, and dry-laid nonwoven fabrics, which are manufactured without using a liquid medium. Wet-laid nonwoven fabric is, for example, paper, and its thickness may be 0.03 to 0.50 mm. The thickness of the dry nonwoven fabric may be 0.5 to 1.5 mm. Woven fabrics, wet nonwoven fabrics, and dry nonwoven fabrics all contain natural fibers, but may also contain semi-synthetic fibers or synthetic fibers, or liquid or solid additives.

In the present invention, from the viewpoint of ease of availability, etc., it is preferable that the sheet 12 is a non-woven fabric. Hereinafter, it will be divided into dry nonwoven fabrics and wet nonwoven fabrics.

[Dry non-woven fabric]

Dry nonwovens are suitable for being compressed and filled into wrappers. Therefore, in this embodiment, in particular, a plurality of sheets of the non-woven fabric 12 are compressed in an S-shaped folded state and filled inside the wrapper 15 (FIG. 2A (1)), or a single sheet of non-woven fabric 12 is formed. It is preferable that the nonwoven fabric 12 is compressed in a folded state and filled inside the wrapper 15, or that a plurality of nonwoven fabrics 12 are compressed and filled in the wrapper 15 (FIG. 2a(2)). In appearance, it is preferable that no gap is visible between the folded nonwoven fabrics in a cross section seen in the axial direction of the cap member 11. This is because the appearance improves. In addition, since the cap member 11 filled in this way has a plurality of gaps between the nonwoven fabrics, there is also an advantage that a heater can be easily inserted.

When a plurality of non-woven fabrics 12 are filled inside the wrapper 15, the compression ratio (A) of the non-woven fabric 12 is preferably 20% or more and less than 100%.

[Calculation method of compression ratio (A)]

Cross-sectional area (A1): Cross-sectional area of the dry nonwoven fabric in the plane perpendicular to the axial direction of the cap member, measured by removing the wrapper of the cap member and taking out the dry nonwoven fabric.

Cross-sectional area (A2): Cross-sectional area of the inside of the cap member in a plane perpendicular to the axial direction of the cap member (A) (%) = (cross-sectional area (A2) / cross-sectional area (A1)) × 100

The lower the value of the compression ratio (A), the more strongly the dry nonwoven fabric is compressed. The compression ratio (A) is preferably 20% or more and less than 100%, more preferably 30 to 80%, and still more preferably 45 to 70%. If the compression ratio A is within this range, an increase in ventilation resistance of the cap member 11 can be appropriately suppressed. The cross-sectional area A1 is the area of a figure (approximately a circle) created by projecting the columnar body formed of nonwoven fabric onto a plane perpendicular to the axial direction after the wrapper is separated. When the wrapper is separated, the nonwoven fabric is released from the compressive force, so the area of the figure formed by the nonwoven fabric usually increases compared to the area of the figure when the wrapper was filled. The cross-sectional area (A1) is measured by the following method. First, the cap member 11 is left at 22°C and a relative humidity of 60% for 24 hours, then the wrapper of the cap member 11 is separated and the nonwoven fabric is taken out. Next, the cross-section of the nonwoven fabric is photographed under a microscope, and the horizontal and vertical lengths are evaluated on the operation monitor to calculate the cross-sectional area (A1). Cross-sectional imaging of the nonwoven fabric can be performed on a cross-section cut from the cap member 11 at any position in the axial direction. In addition, the cross-sectional area (A2) is determined by measuring the outer circumference (circumference) of the cap member 11 with a filter circumference measuring device (product name: SODIMAX, manufactured by SODIM), measuring the thickness of the wrapper with a paper thickness measuring device, and using these measured values. and obtain it by calculation.

The number of non-woven fabrics may be one. However, although it also depends on the thickness of the nonwoven fabric, it is preferable that the number of nonwoven fabrics is 1 to 7 from the viewpoint of good appearance and appropriate ventilation resistance. In addition, in Figure 2a (1), a plurality of nonwoven fabrics are compressed and filled in a folded S-shaped shape, but are formed into shapes other than the S-shaped shape, such as a swirl shape, an accordion shape, or a gathered shape. It may be compressed and filled. In particular, it is preferable that the dry nonwoven fabric is subjected to gather processing. It is preferable that one sheet of processed dry nonwoven fabric is folded and filled inside the wrapper. Alternatively, it is preferable that a plurality of sheets of the processed dry nonwoven fabric are overlapped and folded to fill the inside of the wrapper. In these aspects, the ridges provided by the gather processing extend substantially parallel to the axial direction of the cap member.

The thickness of the nonwoven fabric 12 before filling in this embodiment is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The basis weight of the nonwoven fabric 12 before filling is not particularly limited, but may be, for example, 35 to 60 g/m ² . The basis weight is measured in accordance with JIS P 8124: 2011.

The packing density of the nonwoven fabric 12 filled inside the wrapper 15 is preferably 50 to 150 mg/cm ³ from the viewpoint of more easily achieving ventilation resistance suitable for the absorption of the above-mentioned flavor components. Preferably it is 60 to 140 mg/cm ³ , and more preferably 70 to 130 mg/cm ³ . For example, when the cap member 11 is cylindrical, the weight of the nonwoven fabric is W (mg), the axial length is b (mm), and the circumference is c (mm), the filling density of the nonwoven fabric is calculated by the following equation: It is calculated.

Charge density (mg/cm ³ )=W/((b/10)*(((c/10/π/2) ² )*π))

Examples of natural fibers used in the sheet 12 include silk, wool, cotton, hemp, and plant pulp. These may be used one type or two or more types may be used together. The cap member 11 is exposed to high heat because it exists near the heater. Therefore, it is preferable that natural fibers do not melt even when heated to about 350°C or generate little volatile components. Usually, cellulose acetate fibers used in filters melt at the temperature and generate volatile components with an odor that may affect the flavor generated from the flavor source. In addition, plant pulp is preferable as a natural fiber from the viewpoint of higher dispersibility and decomposability in the natural environment and easy adjustment of ventilation resistance suitable for the absorption of flavor components.

The roughness of the plant pulp is preferably 0.15 to 0.25 mg/m, and is 0.16 to 0.24 mg/m from the viewpoint of more easily achieving ventilation resistance suitable for absorption of the above-mentioned flavor components. It is more preferable, and it is more preferable that it is 0.18 to 0.22 mg/m. In addition, the above-mentioned illuminance is a value measured based on JIS P 8120: 1998.

The sheet 12 may further include chemical synthetic fibers as other fibers in addition to the natural fibers described above. Chemically synthetic fibers include, for example, acetate fibers, rayon fibers, polyamide fibers, acrylic fibers, polyurethane fibers, polylactic acid fibers, polyethylene fibers, polypropylene fibers, polyester fibers, polyethylene terephthalate fibers, polyvinyl alcohol fibers, Examples include polyvinyl acetate fibers and ethylene acetate vinyl copolymer fibers. These may be used one type or two or more types may be used together. When the sheet contains the chemical synthetic fiber, the content of the chemical synthetic fiber in the sheet is preferably 50% by weight or less, more preferably 30% by weight or less.

[Wet-laid non-woven fabric]

In this embodiment, it is preferable that the wet-laid nonwoven fabric 12 is randomly folded and filled into the wrapper 15 in a wrinkled state, as shown in FIG. 2B or FIG. 2C. The ridge (broken line) is approximately parallel to the axial direction of the cap member. More preferably, the wet-laid nonwoven fabric 12 is subjected to a gather process, randomly folded so that its ridges are substantially parallel to the axial direction of the cap member, and filled into the wrapper 15. Although there is a gap between the filled wet nonwoven fabrics 12, it is preferable that the size of the gap is uniform. This is because components volatilized from the flavor source filling are not trapped and leak to the outside, preventing defects such as contamination of the device. The size of the gap is evaluated by the diameter when each gap is converted to a circle.

For the wet-laid nonwoven fabric, the natural fibers described above can be used, and the chemically synthesized fibers described above can also be used. However, in this embodiment, it is preferable that the wet-laid nonwoven fabric 12 is paper. In this case, the thickness is preferably 0.03 to 0.50 mm, and the basis weight is preferably 40 to 400 g/m ² . From the viewpoint of more easily achieving ventilation resistance suitable for the absorption of flavor components, the volume share [%] is 10% or more and less than 60%, preferably 20% or more and less than 60%, more preferably 20 to 40%. . The volume occupancy rate is determined by the thickness and area of the wet nonwoven fabric filling the inside of the cap member, and can be specifically obtained by the following equation.

[Calculation method of volume occupancy (X)]

Cross-sectional area (X1): Total area of the wet-laid nonwoven fabric in the cross-section perpendicular to the axial direction of the cap member

Cross-sectional area (X2): Cross-sectional area inside the cap member in a cross-section perpendicular to the axial direction of the cap member

Volume occupancy rate (X) (%) = (cross-sectional area (X1) / cross-sectional area (X2)) × 100

The cross-sectional area ( Width is the length parallel to the radial direction of the flavor source-containing rod when the wrinkles of the sheet are stretched. The cross-sectional area (X2) is the area of the portion surrounded by the wrapper 15.

The ventilation resistance of the cap member 11 is preferably 0 to 50 mmH ₂ O, more preferably 2 to 30 mmH ₂ O, regardless of the material used, from the viewpoint of being suitable for attracting flavor components. Ventilation resistance was measured using a filter quality measuring instrument (product name: SODIMAX manufactured by SODIM). Specifically, the sample was covered with air-impermeable rubber to prevent air from entering from the side, and a sample was measured at 17.5 cm ³ / from one end. This is the differential pressure (mmH ₂ O) on both end surfaces of the sample when suctioned at a second flow rate.

(1-2) Wrapper

Examples of the material for the wrapper 15 include paper, which has a basis weight of 20 to 120 g/m ² and a thickness of 30 to 150 μm. By setting the basis weight to 20 g/m ² or more, it is difficult for the cylinder to expand due to repulsive force from the nonwoven fabric filled inside the cylinder and cause the circumference to fluctuate. There is no particular limitation on the breathability characteristics of the wrapper, but for example, the breathability is 100 C.U. Examples include using high-permeability paper or low-permeability paper of less than 100 C.U. One with a basis weight of 20 to 100 g/m ² and a thickness of 30 to 120 μm can also be used. Although not particularly limited, LPWS-OLL (air permeability 1300 C.U., basis weight 26.5 g/m ² , thickness 48 μm), P-10000C (air permeability 10000 C.U., basis weight 24.0 g/m ² , thickness 60 μm) manufactured by Nippon Seishi Papyria. ), S-52-7000 (air permeability 7000 C.U., basis weight 52.0 g/m ² , thickness 110 μm), or plain paper (air permeability 0 C.U., basis weight 24 g/m ² , thickness 32 μm). . Rappers can be punished multiple times.

(2) Segment containing flavor source

As shown in FIG. 1, the flavor source-containing segment 13 is a segment in which the flavor source filling 14 is rolled into a cylindrical shape with a wrapper 17. The flavor source-containing segment is preferably cylindrical. The circumferential length is preferably the same as that of the cap member 11, and is specifically 15 to 30 mm. The axial length (length horizontal to the ground) is preferably 6 to 70 mm, more preferably 10 to 30 mm.

(2-1) Flavor source filling

The flavor source filling 14 is a material that generates flavor, and may include tobacco materials, non-tobacco materials, volatile flavor components, and water. A tobacco material is a material that generates a flavor derived from the tobacco plant, and a non-tobacco material is a material that generates a flavor that is not derived from the tobacco plant. A flavor source filling containing tobacco materials is also referred to as a “tobacco filling,” and a flavor source filling containing non-tobacco materials is also referred to as a “non-tobacco filling.”

[Cigarette filling]

There is no limitation on the size of the tobacco used as a cigarette filling or its preparation method. For example, tobacco pieces, tobacco sheets, or tobacco granules can be used. As a piece of tobacco, dried tobacco leaves cut into pieces of 0.8 to 1.2 mm in width may be used. When cut to the above width, the length of the piece is approximately 5 to 20 mm. Additionally, dried tobacco leaves may be pulverized to have an average particle diameter of approximately 20 to 200 μm, processed into sheets, and cut into pieces of approximately 0.8 to 1.2 mm in width and 2 to 4 mm in length. In addition, the sheet processed above may be gathered without cutting and used as a filler. Additionally, a plurality of sheets molded into a cylindrical shape may be arranged concentrically. Whether it is used by cutting dried tobacco leaves or using it as a pulverized and homogenized sheet, various types of tobacco included in the flavor source filling 14 can be used. Yellow species, Burley species, Orient species, native species, and other Nicotiana/Tabacum or Nicotiana/Rustica species can be appropriately blended and used to achieve the desired taste. Details of the tobacco varieties are disclosed in “Dictionary of Tobacco, Tobacco Research Center, March 31, 2009.”

There are multiple methods for grinding tobacco and processing it into a homogenized sheet. The first is to obtain a paper sheet using a papermaking process, and the second is to homogenize the material by mixing an appropriate solvent such as water, then cast the homogenized material thinly on a metal plate or a metal plate belt, and dry it. The third method is to obtain a rolled sheet by mixing and homogenizing an appropriate solvent such as water and extruding it into a sheet shape. Details about the types of the above-mentioned equalization sheets are disclosed in “Dictionary of Tobacco, Tobacco Research Center, March 31, 2009.”

The filling density of the tobacco filling 14 is not particularly limited, but is usually 250 mg/cm ³ or more, preferably 320 mg/cm , from the viewpoint of ensuring the performance of the non-combustion heating type flavor intake mechanism and providing good flavor. ³ or more, and usually 520 mg/cm ³ or less, preferably 420 mg/cm ³ or less. Specifically, the content of the flavor source filler in the tobacco-containing segment 13 is usually 200 to 450 mg, and preferably 280 to 400 mg, per tobacco-containing segment in the case of a tobacco-containing segment with a circumference of 22 mm and a length of 20 mm.

Based on the weight of the tobacco raw material such as leaf tobacco, 10 to 50% by weight, preferably 15 to 30% by weight, of an aerosol generating base may be added. The aerosol generating base is a material that can generate an aerosol by heating, and is not particularly limited, but examples include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1, 3-butanediol, etc. can be mentioned. These may be used one type or two or more types may be used together.

In addition, these volatile fragrance components may be used individually or in combination of two or more types.

[Non-tobacco filling]

As a non-tobacco filling, materials derived from non-tobacco plants can be used. Non-tobacco plant origins include herbal plants (mint, basil, thyme, coriander, rosemary, parsley, fennel, lemongrass, or cinnamon, etc.) or aromatic plants such as tea leaves. Additionally, the plant may be selected from the “List of Natural Fragrance Originating Substances” (2010 News Table No. 337, Annex 2). These plants can be dried, cut to a width of about 0.5 to 1.5 mm, shaped into pieces with a length of about 5 to 20 mm, and randomly oriented and filled in a cylindrical wrapper. Alternatively, the pieces may be filled into the wrapper so that the longitudinal direction of the pieces is approximately parallel to the axial direction of the flavor source-containing segment. You may blend multiple types of plants to match your target flavor.

As a non-tobacco filling, a porous material made from non-tobacco plant fibers can be used. The porous material can be manufactured by the method described for dry nonwoven fabric and wet nonwoven fabric. It is preferable that a flavor source such as fragrance is added to the porous material. The porous material can be cut to a width of about 0.5 to 1.5 mm, shaped into pieces with a length of about 5 to 20 mm, and randomly oriented and filled into a cylindrical wrapper. Alternatively, the piece may be filled into the wrapper so that the longitudinal direction of the piece is approximately parallel to the axial direction of the cap member. Alternatively, the sheet may be folded and filled within a cylindrical wrapper. At that time, it may be filled in a gathered shape (corrugated state).

As a non-cigarette filling, materials derived from polysaccharides can be used. Examples of polysaccharide-derived materials include thickening polysaccharides (gellan gum, carrageenan, pectin, agar), etc. This and water can be mixed, homogenized, and dried to form a sheet. Drying may be performed at room temperature (air drying), heating under reduced pressure, or freeze drying. The filling method for the sheet may be as described above. Alternatively, a polysaccharide-derived material and water homogenized may be formed into granules, and the granules may be filled into a wrapper.

In addition, the polysaccharide-derived material, gelling agent, gelation accelerator, and water are homogenized, a wet gel with a cross-linked structure is prepared, and supercritical carbon dioxide treatment and freeze-drying are performed to remove water while leaving the cross-linked structure. By doing so, it can be said to be a low-density porous gel (gel with an open pore structure). Details of the method are disclosed in International Publication 2019/111536. A wet gel may be prepared by homogenizing the above raw materials by adding a flavor source (flavor, tobacco extract, crushed tobacco, etc.). Alternatively, the flavor source may be added to the porous gel.

(2-2) Wrapper

The flavor source filler (14) is recommended as the wrapper (17). The wrapper 17 can be the same as the wrapper 15 described above. When the filling contains a lot of moisture or an aerosol-generating substrate, it is desirable that the strength of the wrapper does not decrease when these liquids penetrate. From the viewpoint of preventing a decrease in strength, in addition to the wrapper 15 described above, it is preferable to use paper and metal foil bonded together, paper and polymer film bonded together, etc.

2. First mouthpiece segment

The first mouthpiece segment (3) is located downstream of the flavor source-containing rod (1). The first mouthpiece segment 3 is comprised of a cylindrical member 31, and is preferably comprised of a branch pipe 31. Known paper can be used, and its thickness is preferably 200 to 1000 μm. The first mouthpiece segment (3) is connected to the flavor source-containing rod (1) by a mouthpiece lining paper (35). The mouthpiece lining paper 35 and the plain member 31 are provided with a perforation 33 that penetrates both. Due to the presence of the perforations 33, external air is introduced into the segment 3 during suction. As a result, the aerosol vaporization component generated by heating the flavor source-containing segment 13 comes into contact with external air, liquefies as its temperature decreases, and an aerosol is formed. Therefore, the first mouthpiece segment 3 has the function of a cooling segment. The diameter (diameter length) of the perforation 33 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 33 is not particularly limited and may be one or two or more. For example, a plurality of perforations 33 may be provided around the first mouthpiece segment 3.

When inserting the heater 91 from the tip of the flavor source-containing segment 13, a part of the flavor source filling 14 may be pushed into the first mouthpiece segment. In order to prevent this, the paper tube 31 is preferably made of thicker paper than the wrapper 17 for which the flavor source filling 14 is recommended. Additionally, placing a liner inside the paper tube 31 can prevent the flavor source filling 14 from being pushed out. The liner may be made of paper equivalent to the paper constituting the branch pipe 31. Figure 12 shows one aspect of a branch pipe with a liner installed. In the drawing, L is a liner and B is an adhesive.

3. Second mouthpiece segment

The second mouthpiece segment (5) is located downstream of the first mouthpiece segment (3). The second mouthpiece segment 5 has a function of increasing the strength of the flavor aspiration mechanism. Specifically, the second mouthpiece segment 5 is composed of a center hole segment 51 consisting of a filling layer filled with cellulose acetate fibers at high density and a hollow portion provided in the center, and an inner plug wrapper ( 53). The center hole segment 51 may be a rod with an inner diameter of ϕ5.0 to ϕ1.0 mm, which is formed by adding 6 to 20% by weight of a plasticizer containing triacetin to cellulose acetate fiber and hardening it, based on the weight of cellulose acetate. Since the packed layer has a high packing density of fibers, during suction, air or aerosol flows only through the hollow portion and hardly flows inside the packed layer. Additionally, volatile fragrances may be included in the filled layer. By doing this, it becomes possible to include volatile fragrance in the air or aerosol flowing through the hollow part.

4. Third mouthpiece segment

The third mouthpiece segment (7) is located downstream of the second mouthpiece segment (5). The third mouthpiece segment 7 is a solid member and has a function as a filter. The third mouthpiece segment 7 is composed of a filter segment 71 made of a solid cellulose acetate fiber-filled layer, and is wrapped with an inner plug wrapper 73. The second mouthpiece segment 5 and the third mouthpiece segment 7 are connected by an outer plug wrapper 55. The non-combustion heating type flavor aspiration device provided with the third mouthpiece segment 7 has a fiber-filled layer up to the mouth end, and therefore has the same appearance characteristics as a normal cigarette.

The second mouthpiece segment and the third mouthpiece segment may be arranged interchangeably. Additionally, either the second mouthpiece segment or the third mouthpiece segment may be installed.

The third mouthpiece segment may not be a segment solidly filled with cellulose acetate fibers as described above, but may be a segment filled with a wet-laid nonwoven fabric or a dry-laid nonwoven fabric like the cap member 11.

One or more approximately spherical flavor capsules may be placed in the filled fiber bundle of the third mouthpiece segment. A flavor capsule has a shell containing sugars or proteins and a core containing a liquid flavor ingredient. For example, the flavor capsule may be a seamless capsule made by a two-axis nozzle dropping method. The diameter of the approximately spherical capsule is preferably smaller than the diameter of the bottom of the third cylindrical mouthpiece segment.

5. Non-combustible heated flavor aspiration device

The flavor source-containing rod (1), the first mouthpiece segment (3), the second mouthpiece segment (5), and the third mouthpiece segment (7) are connected to form a non-combustion heating type flavor aspiration mechanism (100). do. These are connected by mouthpiece lining paper (35). These connections can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 35 and wrapping the segment.

6. Method of manufacturing cap member 11

The method for manufacturing the cap member 11 according to this embodiment preferably includes a process of compressing a nonwoven fabric containing natural fibers and filling it into a wrapper (hereinafter also referred to as a nonwoven fabric filling process). In addition, the above method further includes a process of forming a nonwoven fabric by a carding method or an air laid dry method, a wet method, a spun bond method, or a melt blow method (hereinafter also referred to as a nonwoven fabric forming process) before the nonwoven fabric filling process. It is desirable to include it. According to the above method, the cap member 11 of this embodiment can be manufactured simply and with high efficiency. Hereinafter, each process will be described using the case of forming a dry nonwoven fabric and the case of forming a wet nonwoven fabric as examples.

[When forming dry nonwoven fabric]

(1) Nonwoven fabric formation process

In this process, nonwoven fabric is formed by a dry method such as a carding method or an air laid method, a wet method, a spun bond method, or a melt blow method. In the formation of a nonwoven fabric, the bonding of fibers including natural fibers can be performed by the thermal bond method, chemical bond method, needle punch method, spunlace method (water lacing method), stitch bond method, or steam jet method. there is.

In this process, it is particularly preferable to form a dry nonwoven fabric by an air-laid dry method and to bond fibers containing natural fibers by a chemical bond method. In the dry air-laid method, a layer of low-density fibers can be formed by air flow. Additionally, the chemical bond method emits a binder and allows fibers to be bonded while maintaining low density. Examples of binders used in the chemical bond method include starch, polyvinyl alcohol, polyvinyl acetate, ethylene vinyl acetate copolymer, and vinyl acrylic acetate copolymer. These binders may be used one type, or two or more types may be used together. When forming a nonwoven fabric by a spun bond method or a melt blow method, or by bonding fibers containing natural fibers by a thermal bond method, the fibers may further include thermoplastic fibers in addition to natural fibers.

(2) Nonwoven filling process

In this process, a dry nonwoven fabric containing natural fibers is compressed and filled into a wrapper. This process preferably includes a step of overlapping a plurality of sheets of nonwoven fabric, a step of folding the overlapping nonwoven fabric into an S-shape, and a step of compressing the nonwoven fabric folded into an S-shape and filling it into a wrapper.

When compressing a nonwoven fabric, the compression ratio (B) calculated by the following method is preferably 20% or more and less than 100%, more preferably 20 to 60%, and still more preferably 25 to 40%. When the compression ratio (B) is 20% or more and less than 100%, the above-described compression ratio (A) in the resulting cap member 11 tends to be 20% or more and less than 100%.

[Calculation method of compression ratio (B)]

Cross-sectional area (B1): Cross-sectional area of the nonwoven fabric immediately before compression in a plane perpendicular to the axial direction of the cap member 11

Cross-sectional area (B2): Cross-sectional area of the nonwoven fabric portion in the plane perpendicular to the axial direction of the cap member 11

Compression rate (B) (%) = (cross-sectional area (B2) / cross-sectional area (B1)) × 100

The cross-sectional area (B1) is calculated by calculating the cross-sectional area of the nonwoven fabric in the plane perpendicular to the axial direction of the cap member 11 by photographing the cross-section of the nonwoven fabric just before compression under a microscope and evaluating the horizontal and vertical lengths on the operation monitor. Measure. In addition, the cross-sectional area (B2) was determined by measuring the outer circumference (circumference) of the cap member 11 with a filter circumference measuring device (product name: SODIMAX, manufactured by SODIM), measuring the thickness of the wrapper with a paper thickness measuring device, and measuring these measured values. It is obtained by calculation using

This process can be performed, for example, using the filter segment manufacturing apparatus shown in FIG. 3. The device includes a nonwoven fabric supply device (S), a nonwoven fabric processing device (W), and a filter segment forming device (F). The nonwoven fabric supply device (S) may be a device that continuously supplies the nonwoven fabric manufactured by the above-described nonwoven fabric forming process to the nonwoven fabric processing device (W).

Details of the nonwoven fabric processing device W are shown in FIG. 4 . The device includes a slitter (W8), a pass part (W9), a level adjustment roller (W10), a vertical roller (W11), an S-shaped guide (W12), a rotor tube (W13), and a forming A member (W14) is provided. The sheet-shaped nonwoven fabric W16 continuously supplied from the nonwoven fabric supply device S is cut into four sheets in the flow direction by the slitter W8. Specifically, as shown in FIG. 5, the nonwoven fabric W16 is equally cut into four pieces in the flow direction by three slit knives W15. In this device, the nonwoven fabric is cut into 4 sheets, but the number of sheets cut is not particularly limited.

Next, the nonwoven fabric W16 cut into four pieces by the slitter W8 are out of phase with each other by the pass part W9. Next, the height of each nonwoven fabric W16 is adjusted by the level adjustment roller W10, and the direction of the sheet of each nonwoven fabric W16 is changed by the vertical roller W11. Specifically, as shown in FIG. 6, the nonwoven fabric W16 passes through the vertical roller W11, thereby changing the direction of the sheet, and then the nonwoven fabrics W16 are arranged to overlap each other slightly. Next, the nonwoven fabric W16 is folded into an S-shaped shape by passing the SS-shaped guide W12. Specifically, as shown in FIGS. 7(a) and 7(b), the SS-shaped guide W12 is misaligned by changing its shape from FIG. 7(a) on the upstream side to FIG. 7(b) on the downstream side. The four sheets of laminated nonwoven fabric W16 are finally folded into an S-shaped shape as shown in FIG. 7(b). FIG. 7(a) is a cross-sectional view along the dotted line (a) in FIG. 4 as seen from the direction in which the sheet W16 is conveyed (left side of the page of FIG. 4), and FIG. 7(b) is a cross-sectional view along the dotted line (b) in FIG. ) is a cross-sectional view viewed from the direction in which the sheet W16 is conveyed (left side of the page in FIG. 4).

Next, the nonwoven fabric W16 folded into an S-shape is compression molded into a cylindrical shape by the rotor tube W13. Specifically, as shown in FIG. 8, the nonwoven fabric W16 folded into an S-shaped shape is inserted into the rotating rotor tube W13 (FIG. 8(b)), and S is rotated by the rotation of the rotor tube W13. As it is compressed while maintaining its square shape, its outer edge is molded into a cylindrical shape (Figure 8(a)). Next, the nonwoven fabric W16 compression-molded into a cylindrical shape is further compressed by the forming member W14 while further strengthening the S-shaped shape. As shown in Fig. 9, a plurality of rotating continuous book rolls W17 installed on the forming member W14 are driven by the forming tape. The continuous book roll W17 may be arranged so that its inner diameter gradually decreases along the flow direction of the nonwoven fabric W16. By passing the nonwoven fabric W16 through the book roll W17 of the forming part, the S-shaped shape can be strengthened more and the nonwoven fabric W16 can be more compression molded into a cylindrical shape. The compression rate (B) can be adjusted within the above-mentioned range by appropriately setting the length and rotation speed of the rotor tube W13, the inner diameter and number of book rolls W17, and the thickness and width of the forming tape.

The nonwoven fabric compression-molded into a cylindrical shape is supplied to the filter segment forming device F shown in FIG. 3, and a wrapper 15 is wound around the outer periphery, pasted, and then cut to an appropriate length. In this way, the cap member 11 is manufactured.

(3) Connection process

The cap member 11 is fixed to the tip of the flavor source-containing segment 14 with a mouthpiece lining paper 35 (see Figure 1b). Alternatively, the cap member 11 is connected to the flavor source-containing segment with an outer wrapper 34 and then connected to the mouthpiece segment with a mouthpiece lining paper 35 (see Fig. 1C).

[In case of forming wet nonwoven fabric]

(1) Nonwoven fabric forming process

In this aspect, it is preferable to form the paper as a wet-laid nonwoven fabric. Paper can be manufactured by known methods, for example, using general papermaking machines such as round mesh papermaking machines, single mesh papermaking machines, long mesh papermaking machines, and incline wire papermaking machines, followed by bleaching. Paper can be manufactured using bleached or unbleached wood pulp as the main raw material. The paper may be a low-permeability paper with an air permeability of less than 100 CU, or a high-permeability paper with an air permeability of 100 CU or more. In addition to wood pulp, the paper may be blended with natural fibers other than wood, or a small amount of chemically synthetic fibers can be blended to ensure the strength of the paper. do.

(2) Nonwoven filling process

In this process, gather processing is performed on the wet nonwoven fabric, and one sheet of processed dry nonwoven fabric can be folded and filled inside the wrapper (see Figure 2c). The ridges provided by the gather processing are approximately parallel to the axial direction of the cap member. The subsequent connection process is as described above.

7. Non-combustion heated flavor aspiration system

The non-combustion heating type flavor aspiration system preferably includes a non-combustion heating type flavor aspiration mechanism and a heating device for heating, and may have other configurations.

An example of a non-combustion heating type flavor aspiration system is shown in Figure 10. In the figure, the non-combustion heating type flavor aspiration system includes a non-combustion heating type flavor aspiration mechanism 100 and a heating device 300 that heats the flavor source-containing segment 13 of the mechanism from the outside. The flavor source-containing segment 13 may be a tobacco-containing segment. Figure 10 shows an aspect of inserting the non-combustion heating type flavor aspiration device 100 into the heating device 300. The heating device 300 is an external heating type heating device that includes a heater 91, a metal tube 93, a body 95, a battery unit 97, and a control unit 99. The body 95 has a normal concave portion, and a heater 91 is installed on the inner side of the concave portion at a position opposite to the flavor source-containing segment 13 of the non-combustion heating type flavor suction device 100 inserted into the concave portion. and a metal pipe 93 are arranged. The heater 91 may be a heater based on electrical resistance, and power is supplied from the battery unit 97 according to instructions from the control unit 99 that performs temperature control. The heat originating from the heater 91 is transmitted to the flavor source-containing segment 13 of the non-combustion heating type flavor suction device 100 through the metal pipe 93 with high thermal conductivity.

The cap member 11 present at the tip of the non-combustion heating type flavor suction device 100 may or may not be heated. Even when heated, the cap member 11 according to this embodiment does not generate volatile components as described above. In addition, as shown in the lower part of FIG. 10, the heater 91 can be arranged so that the gap between the opposing heaters 91 toward the closed end side of the concave portion is narrowed in order to increase gripping properties. there is. In this case, the cap member 11 deforms. However, since the cap member 11 of this embodiment is filled with non-woven fabric with appropriate compressive force, unnecessary channels are not generated.

Figure 11 shows another embodiment of a non-combustion heated flavor inhalation system. The heating device 300 is an internal heating type heating device provided with a heater 91 that can be inserted into the non-combustion heating type flavor aspiration mechanism 100. As the heater 91, it is preferable to use a rigid plate-shaped, blade-shaped, or column-shaped heater. Examples of the heater include ceramic heaters in which molybdenum, tungsten, etc. are applied to a ceramic substrate. The cap member 11 of this embodiment is filled with non-woven fabric so that its main surface is substantially parallel in the axial direction, and there are a plurality of gaps between the non-woven fabrics, so the heater ( 91) can be easily inserted. In addition, it is preferable that the gap is not visible, but in this case, the appearance is also excellent.

The heating temperature by the heating device is not particularly limited, but is preferably 400°C or lower, more preferably 150 to 400°C, and still more preferably 200 to 350°C. Heating temperature refers to the temperature of the heater of the heating device.

Example

[Example 1] Production of cap members A to L

(1) Manufacturing of non-woven fabrics

Nonwoven fabric was manufactured by the air-laid dry method. Specifically, wood pulp as a raw material was first converted into short fibers using a crusher and a fiber mill, and then the pulp was dropped from a web forming device onto the absorbent surface of an endless wire mesh and transported while forming a web. A binder solution containing polyvinyl alcohol and polyvinyl acetate copolymer was sprayed on this web, dried, and the binder solution was further sprayed and dried to obtain a nonwoven fabric with a width of 240 cm (chemical bond method). The obtained nonwoven fabric was wound with a winding device to form a jumbo roll. A nonwoven fabric was supplied from a jumbo roll, slitted to a width of 13 cm, and wound. For the cap members (A to F), wood pulp (manufactured by Weyerhaueser, product name: NB416) with a roughness of 0.22 mg/m was used as the raw wood pulp. For the cap members (G to L), wood pulp (manufactured by UPMRaumacell, product name: Biobright) with a roughness of 0.18 mg/m was used as the raw material. The basis weight of the nonwoven fabric used for the cap members (A to L) was adjusted appropriately.

(2) Preparation of cap-free precursor

The cap member was manufactured using a cigarette filter manufacturing apparatus. That is, the nonwoven fabric manufactured by the method described in (1) was cut into four pieces with a slitter, the four pieces were overlapped, and compressed and molded into a cylindrical shape with an S-shaped cross section. Next, the cylindrical nonwoven fabric is wrapped with a wrapper (LPWS-OLL (air permeability 1300 C.U., basis weight 26.5 g/m ² , thickness 48 μm) manufactured by Nippon Seishi Papyria), the wrap portion is pasted, and then set in a filter manufacturing device. A cap member precursor was obtained by cutting it to a predetermined length with a cutter. The width of the nonwoven fabric before the slit is 130 mm, and when this is slit into four sheets at equal intervals, the width of one sheet becomes 32 mm. Some loss occurred during slitting. In this way, the cap member precursor shown in Table 1 was produced. The axial length of the precursor was 27.0 mm and the circumference was 24.1 mm. In all of the precursors, four sheets of nonwoven fabric each measuring 32 mm in width and 27 mm in length were filled. The precursor was cut to an axial length of 8 mm to obtain a cap member. The physical properties of the cap member are shown in the table below.
