Detailed Description

The present invention will be described in detail below. In the present invention, the range of "X to Y" includes the endpoints X and Y thereof.

1. Tobacco rod

The tobacco rod is a columnar component that generates flavor. The side of the suction port end of the tobacco rod is used as the downstream, and the opposite side is used as the upstream. Fig. 1 shows a schematic configuration of a tobacco rod. Figure 1 is a perspective view of a tobacco rod. In the figure,reference numeral 1 is a tobacco rod,reference numeral 1s is a tobacco rod segment constituting thetobacco rod 1, andreference numeral 1c is a passage for circulating a flavor component in a longitudinal direction. As shown, thechannels 1c are joined discontinuously at the junction of thetobacco rod segments 1 s. Discontinuous joining means joining in such a way that not all but a part of the channels overlap. For ease of understanding, onechannel 1c is shown in eachtobacco rod segment 1s, but there may bemultiple channels 1 c. When there are a plurality of thepassages 1c, one or more discontinuously joinedpassages 1 may be formed in the longitudinal direction of thetobacco rod 1. Further, the channel provided in the longitudinal direction may have one or more discontinuous joint portions. For example, where there are three rod segments, it is sufficient that there is a discrete joint at either the junction of the first and second rod segments or the junction of the second and third rod segments. In the present invention, by providing such a passage, the time for which the aerosol stays in thetobacco rod 1 can be increased, and the volatilization efficiency of the flavor component can be improved. Nicotine is an example of a substance for comparing the volatilization characteristics of flavor components.

The cross-sectional shape of thetobacco rod 1 is not limited, and may be circular, elliptical, polygonal, or rounded polygonal. The size of the cross-sectional shape of thetobacco rod 1 is not limited, but the maximum length (hereinafter also referred to as "width") thereof is preferably 1mm or more, more preferably 3mm or more. The upper limit is preferably 9mm or less, more preferably 7mm or less. The length of thetobacco rod 1 is preferably 40mm or less, more preferably 25mm or less. The lower limit thereof is preferably 1mm or more, more preferably 5mm or more. The length of thetobacco rod section 1s can be adjusted appropriately according to the length of thetobacco rod 1 and the number of tobacco rod sections.

(1) Fragrance source

Thetobacco rod segment 1s is provided with aflavor source 10 containing tobacco. A flavor source (hereinafter simply referred to as "flavor source") 10 containing tobacco forms a channel for aerosol flow in the length direction of thetobacco rod segment 1 s. Therefore, theflavor source 10 containing tobacco is preferably a flavor-generating sheet. As the flavor-generating sheet, a sheet in which a component capable of generating a flavor is supported on a sheet base material or a sheet made of a material capable of generating a flavor can be given. Examples of the component capable of generating flavor include a cigarette flavor component contained in a tobacco material, and a flavor component such as menthol. Examples of the sheet base material include tobacco materials such as compressed tobacco particles and tobacco powder, but the sheet base material is preferably a tobacco material. That is, in the flavor-generating sheet, any one of the sheet base and the flavor-generating component may contain a material derived from tobacco, and in one embodiment, a tobacco sheet in which the flavor-generating component is supported on the sheet base of the tobacco material as necessary is preferable.

1) Channel

Thefragrance source 10 is filled in acylindrical container 12 described later so as to form a passage space in the longitudinal direction. Fig. 2 is a cross-sectional view of atobacco rod segment 1s which is folded as theflavor source 10 into a flavor-generatingsheet 10s and filled into thecylindrical container 12. Fig. 2 (1) shows an embodiment in which the flavor-generatingsheet 10s is filled without being subjected to surface processing, and fig. 2 (2) shows an embodiment in which the flavor-generatingsheet 10s is filled with surface processing such as rolling. The number of the flavor-generating sheets to be filled is not limited, and may be 1 to 3 sheets, but is preferably 1 sheet from the viewpoint of easy manufacturability.

The amount of thefragrance source 10 to be filled is appropriately adjusted, and in one embodiment, is preferably 40 to 90 vol% with respect to the volume of thecylindrical housing 12. A more preferable lower limit may be 50% by volume or more, 55% by volume or more, or 60% by volume or more, and a more preferable upper limit may be 60% by volume or less, 65% by volume or less, 70% by volume or less, 80% by volume or less, or 90% by volume or less, for example. When there are a plurality ofpassages 1c, the cross-sectional area of each passage may be substantially the same, or there may be one or more passages having a larger cross-sectional area than the other passages. In the case of the latter embodiment, however, it is preferred that the channels of greater cross-sectional area are joined in a discontinuous manner.

When the flavor-generatingsheet 10s is used as theflavor source 10, at least one surface of the sheet is preferably subjected to surface processing. The surface processing means processing for forming a plurality of irregularities on the front surface or the back surface of the flavor-generatingsheet 10 s. The surface treatment is not particularly limited, and may be performed by crimping, embossing, knurling, half-cutting, or the like. The crimping process is a process of providing wrinkles on the sheet. For example, by passing the flavor-generatingsheet 10s between a pair of rollers having a plurality of projections on the surface, wrinkles extending orthogonal to the sheet conveying direction can be provided on both the front surface and the back surface of the flavor-generatingsheet 10s, and thus, the crimping process can be performed. The convex portion thus provided extends orthogonal to the sheet conveying direction. The pitch between the apexes of the projections provided on the roller is preferably 0.5 to 2.0 mm. And the apex angle is preferably 30-70 deg. The embossing and the embossing are processes of pressing a convex processing tool against the sheet to form a concave portion on one surface or both surfaces of the sheet, and the half-cut process is a process of providing a notch on one surface or both surfaces of the sheet to such a depth that the sheet is not cut, and preferably to such a depth that the sheet is half or less in thickness.

Further, as thefragrance source 10, a plurality of short strip-shaped fragrance generating sheets may be used. The strip-shaped piece is a piece whose length in the short side direction on the main surface of the piece is smaller than the cross-sectional dimension of thecylindrical housing body 12. Fig. 3 (1) shows a schematic configuration of this embodiment. In the figure,reference numeral 10r is a short-striped fragrance-generating sheet. The flavor-generatingsheet 10r in the form of a short strip is filled so that the longitudinal direction thereof is substantially parallel to the longitudinal direction of thecylindrical container 12. Thetobacco rod section 1s in this embodiment is shown in a sectional view in (2) of fig. 3. The short strip-like flavor-producingsheet 10r may be subjected to the surface processing.

As a method for producing tobacco rods, a method disclosed in Japanese patent application laid-open No. 62-272962 is known, and thetobacco rod segment 1s of the present invention can also be produced by the method described in the publication. In the present invention, however, it is preferable to use reconstituted tobacco sheets as sheet materials instead of reconstituted tobacco materials, and paper-making sheets, pulp sheets, cast sheets are preferably used as reconstituted tobacco sheets. Also, for the strip of sheet material drawn from the bobbin, the surface finishing described in the preceding paragraph can be performed before passing through the cutting device.

2) Preparation of fragrance-producingsheet 10s

The flavor-generatingsheet 10s can be prepared by a known method. For example, the flavor-producingsheet 10s can be prepared by a known method such as paper making, beating, rolling, or the like. Specifically, the paper can be produced by a method including the following steps. 1) The dried tobacco leaf material is coarsely crushed, extracted with water and the water extract is separated from the residue. 2) Drying the water extract under reduced pressure and concentrating. 3) The slurry was added to the residue, and the mixture was refined to be fibrous, followed by papermaking. 4) A concentrated solution of the aqueous extract was added to the sheet after papermaking and dried to form a tobacco sheet.

3) Size of flavor-generatingsheet 10s, etc

The shape of the flavor-generatingsheet 10s is not limited, but the shape of the sheet main surface is preferably a quadrangle. The thickness is not limited, but is preferably 200 to 600 μm in consideration of high-efficiency heat exchange, strength of the flavor-generating tobacco rod segment, and the like. The length of the side a of the flavor-generatingsheet 10s is preferably the same as the length of the cylindrical containingbody 12 in the longitudinal direction. The length of the other side B of the flavor-generatingsheet 10s can be appropriately adjusted, and in one embodiment is 1 to 10 times the length of A.

4) Preparation of short strip-shaped flavor-producingsheet 10r

That is, as shown in fig. 4 (1), thecylindrical housing body 12 can be extended in length to double as thecigarette paper 3. As another embodiment, as shown in fig. 4 (2), thecigarette paper 3 may be provided outside thecylindrical housing body 12. In this embodiment, thecylindrical housing 12 is preferably made of the resin or thick paper.

The direct heating type scent extractor is heated by a well-known heater. The heater is preferably capable of electrically heating thetobacco rod 1 to 200-400 ℃. A general direct heating type flavor absorber includes an internal heating type in which a heater is inserted into thetobacco rod 1 and an external heating type in which a heater is disposed on the outer periphery of thetobacco rod 1. In the present invention, the latter is preferable in order to prevent the structure of the front and rear channels in which the heater is provided from being changed. The combination of a direct heating scent extraction device and a heater is also referred to as a direct heating scent extraction system.

(2) Indirect heating type fragrance suction device

An indirect heating type flavor absorber is an article that generates a flavor by causing an aerosol source disposed upstream of a flavor source to generate an aerosol without directly heating the flavor source, and causing the aerosol to carry a flavor component from the flavor source. Fig. 5 shows an embodiment of an indirect heating type scent extractor. In the figure,reference numeral 200 is an indirect heating type flavor absorber,reference numeral 1 is a tobacco rod,reference numeral 1s is a tobacco rod segment,reference numeral 3 is a tobacco paper,reference numeral 4 is an atomizing part,reference numeral 5 is an external aerosol source, andreference numeral 7 is an outer frame body. Anexternal aerosol source 5 is arranged upstream of thetobacco rod 1 and generates aerosol through theatomizing section 4. Theatomizing unit 4 is preferably capable of electrically heating theexternal aerosol source 5 to about 200 to 300 ℃. The aerosol is generated by the heating, and is guided into thecigarette rod 1, so that the aerosol passes through the fragrance source at the temperature of 30-40 ℃ and bears fragrance components for a user to suck. The combination of an indirectly heated scent extractor and a power source is also referred to as an indirectly heated scent extraction system. Known indirect heating scent extractors and indirect heating scent extraction systems are disclosed, for example, in international publication 2016/075749.

Fig. 6 illustrates a preferred embodiment of an indirect heating-type scent extraction system. In the figure,reference numeral 210 is an indirect heating type flavor extraction system,reference numeral 203 is a power supply unit, andreference numeral 201 is a cartridge. Thecartridge 201 is detachable from thepower supply unit 203. As shown in fig. 7, thecartridge 201 includes anexternal aerosol source 5, anatomizing area 4, and aflow channel 6. The space at the end of the suction opening of thecartridge 201 accommodates thetobacco rod 1. The space in thecartridge 201 accommodates thetobacco rod 1 to constitute the indirectheating flavor absorber 200. Thecartridge 201 may also have a filter at the mouth end.

Theexternal aerosol source 5 can be configured by, for example, supporting the aerosol source on a porous material such as a fibrous wad. The length of theexternal aerosol source 5 is not limited, but is preferably 10 to 25 mm. Thepower supply unit 203 is provided with a power supply such as a battery, and atomizes the aerosol source without combustion.

As theouter frame 7 in the indirect heating type flavor absorber, a frame made of resin can be given. In the embodiment shown in fig. 6, the side wall of thecartridge 201 corresponds to theouter frame 7.

The tobacco rod of the present invention can be used for an ultrasonic vibration flavor absorber, which is one application example of an indirect heating flavor absorber. An ultrasonic vibration type flavor absorber is a flavor absorber in which an ultrasonic oscillation device is used in an atomizing part and vibration is given to an external aerosol source to generate aerosol.

3. Method for manufacturing tobacco rod

Thetobacco rod 1 of the present invention is preferably manufactured through the following steps.

Step 1: a precursor is prepared, which is provided with a cylindrical container and a flavor source that contains tobacco filled in the cylindrical container and is filled so as to form a channel for allowing a flavor component to flow in the longitudinal direction.

And a step 2: the precursor is cut in a direction perpendicular to the longitudinal direction to prepare two or more of the tobacco rod segments.

Step 3: rotating at least one of the tobacco rod sections in the circumferential direction about the longitudinal axis.

Fig. 8 shows an outline of the present manufacturing method. In fig. 8, reference numeral 1' denotes a precursor, reference numeral Y denotes a longitudinal axis, and reference numeral Z denotes a cutting portion.

(1)Step 1

The precursor can be prepared in the same way as thetobacco rod section 1 s.

(2)Step 2

In this step, the precursor 1' is cut in a direction perpendicular to the longitudinal direction. For example, cut at the position Z in fig. 8.

(3)Step 3

In this step, one or more of the tobacco rod segments are rotated in the circumferential direction about the longitudinal axis. The longitudinal axis is an axis passing through the centers of the start end surface and the end surface. The rotation angle is not limited as long as a discontinuously joined passage can be formed. For example, in fig. 8, a tobacco rod segment at the center is rotated by about 30 degrees in the circumferential direction.

Examples

[ example 1]

Using an alkaline aqueous solution of pH9.6, a sheet (thickness 200 μm, grammage 71 g/m) was made of tobacco²Nicotine content 1.4 wt.%). The flavor-generating sheet was cut into a square shape having a length of one side of 21mm and a weight of 310 mg.

A polypropylene tube having a diameter of 8mm, a wall thickness of 0.2mm and a length of 21mm was prepared as a cylindrical container. In the tube, the cut flavor-generating sheet was folded and filled to prepare a precursor. The cross section of the precursor is in the shape of (1) in fig. 2. The precursor was then cut in a direction perpendicular to the longitudinal direction and trisected to obtain three tobacco rod segments. The central tobacco rod section is further rotated by 120 degrees in the circumferential direction by taking the length direction as a central axis. The three tobacco rod segments are then wrapped and spliced with a tipping paper to produce a tobacco rod consisting of three tobacco rod segments.

Referring to the description of international publication 2016/075749, an indirect heating type fragrance suction system described in fig. 6 was prepared. The length of thecartridge 201 is 21mm the same as the length of thetobacco rod 1. The system was used to perform 20 mechanical puffs. The preparation of the test specimens follows ISO (the International Organization for standardization) 3402: 1999 (non-patent literature), a humidity control and harmonization method for tobacco and tobacco products. The mechanical smoking METHOD and the collection METHOD of the generated aerosol are in accordance with CORRESTA RECOMMENDED METHOD No.81 "ROUTINE ANALYTICAL MACHINE FOR E-CIGARETTE AEROSOL GENERATION AND COLLECTION-DEFINITIONS AND STANDARD". And recovering the Cambridge filter disc with the collected aerosol, and measuring the nicotine content by gas chromatography. Cambridge filter is a flat circular glass fiber filter with a diameter of about 44mm and a thickness of 1.5mm, and is widely known and used by those skilled in the art as a filter capable of capturing particulate matter. The cambridge filter sheet can be obtained by cambridge filter corporation of japan, Borgwalt corporation (catalog number 80202852), or the like. Nicotine, which is a representative of flavor components contained in the collected aerosol particulate Matter (hereinafter referred to as "TPM"), was analyzed to determine the amount of nicotine in the TPM. The quantification of nicotine is carried out by methods commonly used by those skilled in the art.

[ example 2]

The precursor was prepared in the same manner as in example 1. Next, the precursor is divided into five equal parts to obtain five tobacco rod segments. The second and fourth tobacco rod segments were rotated in the circumferential direction by 72 degrees about the longitudinal center axis, thereby preparing a tobacco rod consisting of five tobacco rod segments. The tobacco rod was evaluated in the same manner as in example 1.

[ example 3]

A sheet made of tobacco was prepared in the same manner as the sheet made of tobacco used in example 1. Next, the sheet was surface-processed using a crimping roll. As the crimping roller, a mountain roller (60 ℃ C., 1mm pitch) was used. By preparing the flavor-producing sheet in this manner. The flavor-generating sheet was cut into a shape having a length of 21mm and a weight of 310mg on one side. Using the cut sheet, tobacco rods composed of five tobacco rod segments as in example 2 were produced and evaluated.

Comparative examples 1 and 2

Tobacco rods consisting of one and five tobacco rod segments were produced and evaluated in the same manner as in examples 1 and 3, except that the precursor was used as a tobacco rod without cutting. These results are shown in table 1 and fig. 9.

[ Table 1]

As shown in table 1, the tobacco rods of the examples have higher values than those of the comparative examples with respect to the ratio of flavor components contained in the particulate matter of the aerosol generated from the tobacco rods. It is apparent that the tobacco rod of the present invention has excellent volatilization characteristics of flavor components.
