Disclosure of Invention
Problems to be solved by the invention
In reference 1, a structure for holding a flavor generating article inserted into a chamber is disclosed. However, there is no means for easily perceiving that the end of the chamber has been reached when the flavour generating article is inserted into the chamber, and for easily foreseeing that the end of the chamber is to be reached. That is, since it is difficult to feel that the end of the chamber has been reached and it is difficult to anticipate that the end of the chamber will be reached, the fragrance-generating article is sometimes pressed too strongly, resulting in deformation of the fragrance-generating article.
If the flavor generating article is not disposed at an appropriate position with respect to the heating portion of the flavor inhaler, the flavor generating article (particularly, the filling portion filled with the smokable article) may be insufficiently heated, and may undesirably affect the flavor. Therefore, in order to be able to arrange the flavour generating article in a suitable position within the chamber, it is important that the end of the chamber has been reached is easily perceived and it is easy to anticipate that the end of the chamber will be reached.
The present invention has been made to solve at least a part of the above-described problems, and an object of the present invention is to provide a smoking system in which a user can easily feel that the user has reached the end of a chamber when inserting a flavor-generating article into the chamber, and can easily anticipate that the user will reach the end of the chamber.

A≤4.00N…(1)
B＞1.0…(2)，
the first half average resistance is an average value of resistance values from a predetermined position on the insertion end side of the housing portion to an intermediate point between the predetermined position and the distal end of the housing portion, and the second half average resistance is an average value of resistance values from an intermediate point between the predetermined position and the distal end of the housing portion to the distal end of the housing portion.
According to the first aspect of the present invention, when the odor-causing article is inserted into the storage portion, the end of the storage portion is perceived as having been reached, and when the expression (2) is satisfied, the end of the storage portion is perceived as being reached due to the rising sense of the insertion resistance on the side close to the end of the storage portion, so that it is easy to predict that the end of the storage portion is to be reached.
In the first aspect of the present invention, the predetermined position on the insertion end side of the housing portion may be a position 10mm from the distal end of the housing portion. The intermediate point between the predetermined position and the end of the housing portion may be a position 5mm from the end of the housing portion. In this case, the first-half average resistance may be an average value of resistance values in a range of 10mm to 5mm from the end of the housing portion, and the second-half average resistance may be an average value of resistance values in a range of 5mm to 0mm from the end of the housing portion.

According to the second aspect of the present invention, by providing a local variation in the resistance value, the user can easily perceive the approach of the end of the housing portion, and can more easily predict that the end of the housing portion is to be reached.
In a third aspect of the present invention, according to the second aspect, when the ratio of the resistance value in the local fluctuation region to the insertion force is set to the second resistance ratio C, the following expression (3) is satisfied.
C≥0.8…(3)
According to the third aspect of the present invention, by satisfying the expression (3), the resistance value in the local fluctuation region is significantly smaller than the insertion force, and thus, it is possible to suppress the foreseeable situation that does not contribute to reaching the end of the housing portion.
In a fourth aspect of the present invention, according to the second or third aspect, when a distance from the end position of the storage portion to the local variation region is set to a distance D, the following expression (4) is satisfied.
D≤5.0mm…(4)
According to the fourth aspect of the present invention, by satisfying the expression (4), the user can maintain the sense of passing through the local fluctuation range until reaching the end of the housing portion, and therefore it is easier to predict that the end of the housing portion will be reached.

As shown in fig. 1A to 1C, the fragrance absorber 100 includes an outer cover 101, a slide cover 102, a switch 103, and terminals 104. The outer cover 101 constitutes the outermost cover of the fragrance absorber 100, and has a size to be accommodated in the hand of the user. When the user uses the fragrance dispenser 100, the user can hold the fragrance dispenser 100 by hand and can suck aerosol. The outer cover 101 may be formed by assembling a plurality of members. The outer cover 101 may be formed of a metal such as aluminum. The outer cover 101 may be made of a resin, for example, a Polycarbonate (PC), an ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of polymers.
The outer cover 101 has an opening, not shown, for receiving the fragrance-generating article, and the slide cover 102 is slidably attached to the outer cover 101 to close the opening. Specifically, the slide cover 102 is configured to be movable along the outer surface of the outer cover 101 between a closed position (position shown in fig. 1A and 1B) in which the opening of the outer cover 101 is closed, and an open position in which the opening is opened. The sliding cover 102 can be moved to the closed position and the open position by, for example, a user manually operating the sliding cover 102. This allows or restricts the entry of the fragrance generating article into the slide cover 102 and the fragrance absorber 100.
The switch 103 is used to switch the operation of the fragrance absorber 100 on and off. For example, by operating the switch 103 in a state in which the flavor generating article is inserted into the flavor inhaler 100, the user can supply electric power from a power source, not shown, to a heating unit, not shown, to heat the flavor generating article without burning. The switch 103 may be a switch provided outside the outer cover 101 or may be a switch provided inside the outer cover 101. When the switch is located inside the outer cover 101, the switch is indirectly pressed by pressing the switch portion 103 on the surface of the outer cover 101. In the present embodiment, an example will be described in which the switch of the switch unit 103 is located inside the outer cover 101.
The terminal 104 is an interface such as USB for connecting the fragrance absorber 100 to an external power supply. When the power source provided in the fragrance extraction device 100 is a rechargeable battery, the external power source is connected to the terminal 104, so that the external power source can supply a current to the power source, thereby charging the power source. Further, the fragrance absorber 100 may be configured to be able to transmit data related to the operation of the fragrance absorber 100 to an external device by connecting a data transmission cable to the terminal 104.
Next, a flavor generating article used in the flavor inhaler 100 according to the present embodiment will be described. Fig. 2 is a schematic side cross-sectional view of the flavor generating article 110. In the present embodiment, the flavor inhaler 100 and the flavor generating article 110 may constitute a smoking system. In the example shown in fig. 2, the flavor generating article 110 may have a filler 111 filled with a smokable article, and a filter section including a filter portion 115 and a hollow filter portion 116. The hollow filter 116 may be located on the smokable object side of the filter 115. Specifically, the flavor generating article 110 may be a rod-shaped non-combustion heated tobacco, and includes a smokable article, a mouthpiece portion, and a second roll paper 113 such as tipping paper, which is formed by wrapping them. The mouthpiece portion has a cylindrical member 114 and a filter section. The filter section has a hollow filter portion 116 and a filter portion 115. The cylindrical member 114 as a cooling section may be held between the smokable article and the filter section in an abutting relationship with respect to the axial direction (also referred to as the "long axis direction") of the flavour generating article 110. Further, the cylindrical member 114 may be provided with the openings V concentrically along the circumferential direction of the cylindrical member 114. The opening V of the tubular member 114 provided in the flavor generating article 110 is generally a hole for promoting inflow of air from the outside due to suction by a user, and the temperature of the component or air flowing from the smokable article can be reduced by the inflow of air.
The rod-shaped flavor generating article 110 is preferably a columnar shape having a shape satisfying the aspect ratio 1 or more defined as follows.
Aspect ratio = h/w
w is the width of the bottom surface of the columnar body (in this specification, the width of the bottom surface on the smokable article side), and h is the height, preferably h.gtoreq.w. In the present specification, the long axis direction is defined as a direction indicated by h. Thus, it is assumed that in the case where w.gtoreq.h, the direction denoted by h is also referred to as the long axis direction for convenience. The shape of the bottom surface is not limited, and may be a polygon, a rounded polygon, a circle, an ellipse, or the like, and the width w is a diameter in the case of the bottom surface being a circle, a long diameter in the case of the ellipse, or a diameter of an inscribed circle or a long diameter of an circumscribed ellipse in the case of the polygon or the rounded polygon.
The flavour generating article 110 may also have a first roll 112 of wrapped smokable article. The length of the flavor generating article 110 in the longitudinal direction is preferably 40 to 90mm, more preferably 50 to 75mm, and even more preferably 50 to 60mm. More specifically, the length h of the flavor generating article 110 in the longitudinal direction is not particularly limited, and is, for example, usually 40mm or more, preferably 45mm or more, and more preferably 50mm or more. The length h of the flavor generating article 110 in the longitudinal direction is usually 100mm or less, preferably 90mm or less, and more preferably 80mm or less. The circumference of the flavor generating article 110 is preferably 15mm to 25mm, more preferably 17mm to 24mm, and even more preferably 20mm to 23mm. More specifically, the width w of the bottom surface of the columnar body of the flavor generating article 110 is not particularly limited, and is, for example, usually 5mm or more, preferably 5.5mm or more. The width w of the bottom surface of the columnar body of the flavor generating article 110 is usually 10mm or less, preferably 9mm or less, and more preferably 8mm or less. The smokable material in the flavor generating article 110 may have a length of 18 to 22mm, the first roll paper 112 may have a length of 18 to 22mm, the hollow filter 116 may have a length of 7 to 9mm, and the filter 115 may have a length of 6 to 8mm.
The ratio of the length of the tubular member 114 and the length of the filter segment (tubular member 114: filter segment) in the longitudinal direction of the flavor generating article 110 is not particularly limited, but is generally 0.60 to 1.40 from the viewpoints of the amount of flavor to be delivered and the appropriate aerosol temperature: 0.60 to 1.40, preferably 0.80 to 1.20:0.80 to 1.20, more preferably 0.85 to 1.15:0.85 to 1.15, more preferably 0.90 to 1.10:0.90 to 1.10, particularly preferably 0.95 to 1.05:0.95 to 1.05. By setting the ratio of the lengths of the tubular member 114 and the filter segments to be within the above range, the cooling effect, the effect of suppressing the loss caused by the generated vapor and aerosol adhering to the inner wall of the tubular member 114, and the balance of the air amount of the filter and the flavor adjusting function can be achieved, and a good flavor and flavor intensity can be achieved. In particular, if the tubular member 114 is lengthened, granulation of aerosol or the like can be promoted to realize a good flavor, but if it is too long, adhesion of the passing substance to the inner wall occurs.
The configuration of the mouthpiece portion is not particularly limited as long as the tubular member 114 is held between the smokable article and the filter segment so as to be adjacent to the axial direction of the flavor generating article 110. In other words, the flavour generating article 110 may have a cylindrical component 114 between the smokable article and the filter segment. Hereinafter, the filter segment and the tubular member 114 will be described in detail.
(disclosure relating to filter segments)
The filter section includes a filter portion 115, and is not particularly limited as long as it has a function as a general filter. Typical functions of the filter include, for example, adjustment of the amount of air mixed during inhalation of aerosol, reduction of flavor, reduction of nicotine and tar, and the like, but these functions need not be all provided. In addition, in an electrically heated tobacco product which generates less components than a cigarette product and which tends to decrease the filling rate of a tobacco filler, it is also one of important functions to suppress the filtration function and prevent the tobacco filler from falling down.
(disclosure relating to size)
The cross-sectional shape of the filter segment in the circumferential direction is substantially circular, and the diameter of the circle can be appropriately changed depending on the size of the product, but is usually 4.0mm to 9.0mm, preferably 4.5mm to 8.5mm, more preferably 5.0mm to 8.0 mm. In the case where the cross section is not circular, the diameter in a circle having the same area as the cross section is applied to the diameter described above. The length of the circumference of the cross-sectional shape of the filter segment in the circumferential direction may be appropriately changed depending on the size of the product, but is usually 14.0mm to 27.0mm, preferably 15.0mm to 26.0mm, more preferably 16.0mm to 25.0 mm. The axial length of the filter segment may be appropriately changed depending on the size of the product, but is usually 15mm to 35mm, preferably 17.5mm to 32.5mm, more preferably 20.0mm to 30.0 mm. The shape and size of the mouthpiece filter may be appropriately adjusted so that the shape and size of the filter section 115 fall within the above-described ranges.
(disclosure relating to the filter portion 115)
The filter portion 115 constituting the filter segment may be, for example, a filter manufactured by a manufacturing method described later, or a commercially available product. The manner of the filter segments is not particularly limited, and may be a normal filter (plain filter) including a single filter segment, a multi-segment filter including a plurality of filter segments such as a double filter or a triple filter, or the like. The filter segment can be produced by a known method, for example, in the case where synthetic fibers such as cellulose acetate tow are used as the material of the filter portion 115, it can be produced by spinning and crimping a polymer solution containing a polymer and a solvent. As this method, for example, the method described in international publication No. 2013/067511 can be used. In the manufacture of the filter segment, adjustment of ventilation resistance, addition of additives (known adsorbents, flavors (e.g., menthol), granular activated carbon, flavor-retaining materials, etc.) to the filter portion 115 may be appropriately designed. The manner of forming the filter portion 115 of the filter segment is not particularly limited, and a known manner may be employed, and for example, a manner of processing cellulose acetate tow into a cylindrical shape may be cited. The filament fineness and the total fineness of the cellulose acetate tow are not particularly limited, but in the case of a 22mm circumference of the mouthpiece portion, the filament fineness is preferably 5g/9000m to 12g/9000m, and the total fineness is 12000g/9000m to 35000g/9000 m. The cross-sectional shape of the fibers of the cellulose acetate tow may be circular, elliptical, Y-shaped, I-shaped, R-shaped, or the like. In the case of the filter portion 115 filled with cellulose acetate tow, in order to increase the hardness of the filter, triacetin (plasticizer) may be added in an amount of 5 to 10% by weight based on the weight of the cellulose acetate tow. In addition, instead of the acetate filter, a filter paper filled with a sheet-like pulp paper may be used.
(disclosure relating to hollow filter portion 116)
The filter section may also include a hollow filter portion 116 having one or more hollows. The hollow filter 116 is generally disposed closer to the tubular member 114 than the filter 115, and is preferably disposed adjacent to the tubular member 114.
The hollow filter portion 116 is composed of a filler layer having one or more hollow portions and an inner plug wrap (inner roll paper) covering the filler layer. The hollow portion can be provided at any position of the hollow filter portion 116. The hollow filter unit 116 has a function of improving the strength of the mouthpiece portion. The filler layer may be, for example, a rod in which cellulose acetate fibers are filled at a high density, and a plasticizer containing triacetin is added in an amount of 6 to 20 mass% based on the mass of cellulose acetate and cured. The inner diameter of the hollow filter 116 isAbove->The following is given. The filling layer has higher filling density of fiber, so that air,The aerosol flows only through the hollow portion and hardly flows in the filler layer. Since the filler layer inside the hollow filter unit 116 is a fiber filler layer, the feeling from the outside at the time of use makes the user feel less uncomfortable. Alternatively, the hollow filter 116 may be formed by thermoforming without the inner plug wrap. The hardness of the hollow filter portion 116 is preferably greater than that of the filter portion 115. Specifically, the mass percentage of the plasticizer contained in the hollow filter portion 116 is preferably larger than the mass percentage of the plasticizer contained in the filter portion 115. In the flavor generating article 110, when it is desired to reduce the reduction caused by the filtration of the aerosol components in the filter portion 115, it is effective to shorten the length of the filter portion 115 and replace it with the hollow filter portion 116 in order to increase the amount of aerosol delivered.
(disclosure relating to filter Density)
The density of the filter portion 115 is not particularly limited, but is usually 0.10g/cm 3 Above 0.25g/cm 3 Hereinafter, it is preferably 0.11g/cm 3 Above 0.24g/cm 3 Hereinafter, more preferably 0.12g/cm 3 Above 0.23g/cm 3 The following is given.
(disclosure relating to filter tip wrapper (inside, outside, winding paper)

The thickness of the rolled paper is not particularly limited, and is usually 20 μm to 140 μm, preferably 30 μm to 130 μm, more preferably 30 μm to 120 μm. The grammage of the roll paper is not particularly limited, and is usually 20 to 100gsm, preferably 22 to 95gsm, and more preferably 23 to 90 gsm. The roll paper may or may not be coated, but is preferably coated with a desired material from the viewpoint of being able to impart functions other than strength and structural rigidity.
The hollow filter 116 and the filter 115 may be connected by, for example, an outer plug wrap (outer wound paper). The outer plug wrap may be, for example, cylindrical paper. The smokable material, the tubular member 114, the hollow filter 116 after connection, and the filter 115 may be connected by, for example, a mouthpiece paper (second roll paper 113). The connection may be performed by applying a paste such as a vinyl acetate paste to the inner side of the mouthpiece backing paper, putting the smokable material, the tubular member 114, the hollow filter 116 after connection, and the filter 115, and winding them. Alternatively, they may be joined by a plurality of interleaving papers in a plurality of steps.
(disclosure relating to addition of activated carbon)
Activated carbon may be added to at least a part of the filter portion 115. Regarding the addition amount of activated carbon, in 1 flavor-generating article 110, the value of the specific surface area of activated carbon×the weight of activated carbon/the cross-sectional area of filter portion 115 perpendicular to the ventilation direction was 15.0m 2 /cm 2 Above 80.0m 2 /cm 2 The following is given. For convenience, the above-described "specific surface area of activated carbon×weight of activated carbon/cross-sectional area of the filter portion 115 in the direction perpendicular to the ventilation direction" may be expressed as "surface area of activated carbon per unit cross-sectional area". The surface area of the activated carbon per unit cross-sectional area can be calculated based on the specific surface area of the activated carbon added to the filter portion 115 of 1 flavor generating article 110, the weight of the activated carbon added, and the cross-sectional area of the filter portion 115. In addition, the activated carbon may not be uniformly dispersed in the filter portion 115 to which the activated carbon is added, and it is not required to satisfy the above range in all cross sections (cross sections perpendicular to the ventilation direction) of the filter portion 115. By making the surface area of the activated carbon per unit cross-sectional area within the above-mentioned range, the catalyst can be used The component generated by heating can be delivered to the user in a desired amount and impart a desired flavor sensation to the user. If the surface area of the activated carbon per unit cross-sectional area is smaller than the lower limit of the above range, the effect of adding the activated carbon cannot be sufficiently obtained. On the other hand, if the surface area of the activated carbon per unit cross-sectional area is larger than the upper limit of the above range, the component generated by heating is reduced to be more than necessary.
The surface area of the activated carbon per unit cross-sectional area is more preferably 17.0m 2 /cm 2 Above, more preferably 35.0m 2 /cm 2 The above. On the other hand, more preferably 77.0m 2 /cm 2 Hereinafter, 73.0m is more preferable 2 /cm 2 The following is given. The surface area of the activated carbon per unit cross-sectional area can be adjusted by adjusting the specific surface area of the activated carbon, the amount of the activated carbon added, and the cross-sectional area of the filter portion 115 in the direction perpendicular to the ventilation direction, for example. The calculation of the surface area of the activated carbon per unit cross-sectional area is based on the filter portion 115 to which the activated carbon is added. In the case where the filter segment is composed of a plurality of filter segments 115, the cross-sectional area and length of the filter segment 115 to which activated carbon is added are used as the basis.
Examples of the activated carbon that can be used in the present embodiment include activated carbon made of wood, bamboo, coconut shell, walnut shell, coal, and the like. In addition, as the activated carbon that can be used in this embodiment, a BET specific surface area of 1100m can be used 2 1600 m/g or more 2 Less than/g, preferably 1200m 2 /g 1500m 2 Preferably less than/g, more preferably 1250m 2 1380 m/g or more 2 Activated carbon of less than/g.

In this embodiment, the specific surface area of the activated carbon and the amount of activated carbon added are set to the above-described ranges, whereby the surface area of the activated carbon per unit cross-sectional area can be adjusted to a desired surface area. Further, as the activated carbon that can be used in the present embodiment, activated carbon having a cumulative 10 vol% particle diameter (particle diameter D10) of 250 μm to 1200 μm is preferable. The cumulative 50% by volume particle diameter (particle diameter D50) of the activated carbon particles is preferably 350 μm to 1500 μm. D10 and D50 were measured by a laser diffraction scattering method. Examples of a device suitable for the measurement include a laser diffraction/scattering particle size distribution measuring device "LA-950" manufactured by horiba, ltd. In the unit of the apparatus, the powder is flowed together with pure water, and the particle diameter is detected based on the light scattering information of the particles. The measurement conditions based on this apparatus are as follows.
Measurement mode: manual inflow mode cell assay

On the other hand, in the case of a plurality of filter segments, the activated carbon-added filter portion 115 is preferably disposed upstream of the filter portion 115 constituting the suction port end. On the other hand, activated carbon may be added to the filter portion 115 constituting the suction port end. In the case where the filter segment is a multi-segment filter, the length of the filter segment serving as a reference for the amount of activated carbon added is the length of the filter segment 115 to which activated carbon is added. The amount of activated carbon added may be, for example, 4.0mg to 24.0mg, preferably 4.5mg to 23.0mg, more preferably 10.5mg to 22.0mg, based on the weight of the entire filter segment.

The shape of the flavor source such as tobacco may be a tobacco thread, a sheet, a rope, a powder, a granule, a pellet, a slurry, a porous material, or the like. Specifically, for example, dried tobacco leaves may be crushed into tobacco crushed materials having an average particle diameter of 20 μm to 200 μm, homogenized, subjected to sheet processing (hereinafter, also simply referred to as "homogenized sheet"), and then cut. Further, a so-called strand (strand) may be formed by cutting up a uniform sheet having a length substantially equal to the length of the smokable article and substantially horizontally extending in the length direction of the smokable article and filling the cut sheet with the smokable article. The sheet after the sheet processing may be used as a smokable article by performing a pleat processing without shredding. The width of the tobacco filaments is preferably 0.5mm to 2.0mm when the tobacco filaments are filled into the smokable material. The content of the smokable material such as tobacco in the flavor generating article 110 is, for example, 200mg to 400mg, preferably 250mg to 320mg, in the case where the smokable material has a size of 20mm to 23mm in circumference and a length of 18mm to 22 mm.

Examples of the variety include yellow variety, burley (Burley) variety, oriental variety, local variety, other tobacco (Nicotiana tabacum) variety, yellow tobacco (Nicotiana rustica) variety, and mixtures thereof. The above-mentioned respective kinds of the mixture may be appropriately mixed and used for obtaining a desired taste. Details of the variety of the tobacco are disclosed in "tobacco dictionary, comprehensive tobacco research center, 2009.3.31". There are various existing methods for manufacturing the uniform sheet, that is, the method of pulverizing tobacco leaves and processing the tobacco leaves into the uniform sheet. The first is a method of producing a paper sheet using a papermaking process. The second method is a method of mixing and homogenizing a suitable solvent such as water into crushed tobacco leaves, and then casting the homogenized product thinly on a metal plate or a metal plate belt, drying it, and producing a cast sheet. The third method is a method of producing a rolled sheet by mixing a suitable solvent such as water into crushed tobacco leaves, homogenizing the mixture, and extruding the homogenized mixture into a sheet. The type of the homogeneous sheet is disclosed in detail in "tobacco dictionary, comprehensive tobacco research center, 2009.3.31".
The moisture content of the tobacco filler may be 8 wt% or more and 18 wt% or less, preferably 10 wt% to 16 wt%, more preferably 10 wt% or more and 15 wt% or less, and still more preferably 11 wt% or more and 13 wt% or less, with respect to the total amount of the tobacco filler. When the moisture content is such, generation of paper roll dirt is suppressed, and rolling-up suitability in producing a smokable article is improved. Further, the flavor generating article 110 is easily deformed appropriately in accordance with the cross-sectional shape of the holding portion. The size of the tobacco filaments contained in the first tobacco filler and the method for producing the same are not particularly limited. For example, the dried tobacco leaves may be cut into pieces of a width of 0.5mm to 2.0mm, preferably 0.8mm to 1.2 mm. In the case of using a crushed product of a uniform sheet, it is also possible to use a sheet obtained by crushing and homogenizing dried tobacco leaves to an average particle diameter of about 20 to 200 μm, and then cutting the crushed product into a sheet having a width of 0.5 to 2.0mm, preferably 0.8 to 1.2 mm.
The first tobacco filler may also comprise an aerosol substrate that generates aerosol smoke. The type of the aerosol base material is not particularly limited, and the extract material derived from various natural substances and/or the constituent components thereof may be selected according to the purpose. Examples of the aerosol base material include glycerin, propylene glycol, triacetin, 1, 3-butanediol, and a mixture thereof. The content of the aerosol base material in the first tobacco filler (weight% relative to the weight of the first tobacco filler) is not particularly limited, and is usually 5 weight% or more, preferably 10 weight% or more, and further usually 50 weight% or less, preferably 15 weight% or more and 25 weight% or less relative to the total amount of the tobacco filler, from the viewpoint of sufficiently generating an aerosol and imparting a good flavor.
The first tobacco filler may also comprise a flavoring. The type of the perfume is not particularly limited, and may be the same perfume as the above perfume added to the filter portion 115 from the viewpoint of imparting a good fragrance.
The content of the flavor in the first tobacco filler is not particularly limited, but is usually 10000ppm or more, preferably 20000ppm or more, more preferably 25000ppm or more, and is usually 70000ppm or less, preferably 50000ppm or less, more preferably 40000ppm or less, more preferably 33000ppm or less, from the viewpoint of imparting a good flavor.
The filling density in the first tobacco filler is not particularly limited, but is usually 250mg/cm from the viewpoint of securing the performance of the flavor-generating article 110 and imparting a good flavor 3 Above, preferably 300mg/cm 3 Above, in addition, it is usually 400mg +.cm 3 Hereinafter, it is preferably 350mg/cm 3 The following is given. The first tobacco filler is wrapped with a roll paper so as to be inside, thereby forming a smokable article.
(disclosure relating to filler (second tobacco filler: sheet filler))
The second tobacco filler is composed of tobacco sheets filled with the filler. The number of the tobacco sheets may be 1 or 2 or more. As a method for forming the second tobacco filler from 1 sheet of tobacco sheet, for example, a filling method (so-called pleated sheet) in which a tobacco sheet having a length equal to the longitudinal direction of the filler on one side and the longitudinal direction of the filler are folded back a plurality of times horizontally is exemplified. Further, a tobacco sheet having a length substantially equal to the longitudinal direction of the filler is wound around the filler in a direction orthogonal to the longitudinal direction of the filler.
As a mode in which the second tobacco filler is made up of 2 or more tobacco sheets, for example, a mode in which a plurality of tobacco sheets each having a length of 1 side substantially equal to the longitudinal direction of the filler are arranged concentrically and are wound in a direction orthogonal to the longitudinal direction of the filler is used. "concentrically disposed" means that the centers of all the tobacco sheets are disposed at substantially the same position. The number of the tobacco sheets is not particularly limited, but 2, 3, 4, 5, 6, or 7 sheets may be used. The tobacco sheets may be all of 2 or more pieces of the same composition or physical properties, or may be partially or completely different in composition or physical properties. The thicknesses of the respective tobacco sheets may be the same or different.
The second tobacco filler may be manufactured by: a plurality of tobacco sheets having different widths are prepared, a laminate is prepared in which the width is reduced from the bottom to the top, and the laminate is rolled up and formed by a roller tube. According to the manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Further, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost tobacco sheet.
In this manufacturing method, it is preferable that the laminate is prepared so that a non-contact portion is formed between the adjacent tobacco sheets after roll-forming. If there are non-contact portions (gaps) between the plurality of tobacco sheets, which are not in contact with the tobacco sheets, the flavor flow path can be ensured, and the efficiency of delivering the flavor component can be improved. On the other hand, since heat from the heater can be transferred to the tobacco sheet on the outside via the contact portions of the plurality of tobacco sheets, high heat conduction efficiency can be ensured. In order to provide a non-contact portion where the tobacco sheets are not in contact with each other between a plurality of tobacco sheets, for example, a method of preparing a laminate by using embossed tobacco sheets, laminating adjacent tobacco sheets so that the entire surfaces of the adjacent tobacco sheets are not adhered to each other, laminating adjacent tobacco sheets so that a part of the adjacent tobacco sheets are adhered to each other, or laminating adjacent tobacco sheets so that the entire surfaces or a part of the adjacent tobacco sheets are slightly adhered to each other so as to peel off after roll forming can be cited. In the case of preparing a smokable article comprising a roll paper, the roll paper may be disposed at the bottommost portion of the laminate. Further, a cylindrical mold such as a mandrel may be placed on the top of the laminate to form the second tobacco filler, and then the mold may be removed to form the fitting portion.
The filling density of the second tobacco filler is not particularly limited, but is usually 250mg/cm from the viewpoint of securing the performance of the tobacco product and imparting good flavor 3 Above, preferably 300mg/cm 3 The above, in addition, is usually 400mg/cm 3 Hereinafter, it is preferably 350mg/cm 3 The following is given.
The tobacco sheet may also contain an aerosol substrate that generates aerosol smoke upon heating. As the aerosol base material, an aerosol source such as a polyol such as glycerin, propylene glycol, 1, 3-butanediol, or the like is added. The amount of the aerosol base material to be added is preferably 5 to 50% by weight, more preferably 15 to 25% by weight, based on the dry weight of the tobacco sheet.
The tobacco sheet can be suitably produced by a known method such as papermaking, sizing, rolling, and the like. In addition, the homogeneous pieces described in the first tobacco filler can also be used. In the case of papermaking, the paper can be produced by a method comprising the following steps. 1) Coarse pulverizing dried tobacco leaves, extracting with water, and separating into water extract and residue. 2) The aqueous extract was dried under reduced pressure and concentrated. 3) Pulp was added to the residue, which was fibrillated by a refiner, and then papermaking was performed. 4) The aqueous extract concentrate is added to the sheet after papermaking and dried to obtain a tobacco sheet. In this case, a step of removing a part of components such as nitrosamine may be added (see JP-A2004-510422). In the case of the slurry method, the slurry method can be produced by a method including the following steps. 1) Mixing water, pulp and binder with the crushed tobacco. 2) The mixture was spread (cast) thinner and dried. In this case, a step of removing a part of components such as nitrosamine by ultraviolet irradiation or X-ray irradiation of a slurry in which water, pulp, a binder and crushed tobacco are mixed may be added.
In addition, as described in international publication No. 2014/104078, a nonwoven fabric-like tobacco sheet produced by a method including the following steps may be used. 1) Mixing the granular tobacco leaves with a binding agent. 2) The mixture was sandwiched by nonwoven fabrics. 3) The laminate was formed into a predetermined shape by thermal fusion, and a nonwoven fabric-like tobacco sheet was obtained. The tobacco leaves used in the above methods can be of the same type as described for the first filler. The composition of the tobacco sheet is not particularly limited, but for example, the content of the tobacco raw material (tobacco leaf) is preferably 50% by weight or more and 95% by weight or less relative to the total weight of the tobacco sheet. The tobacco sheet may contain a binder, and examples of the binder include guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), and the like. The binder amount is preferably 1 wt% or more and 10 wt% or less based on the total weight of the tobacco sheet. The tobacco sheet may also contain other additives. Examples of the additive include fillers such as pulp. In the present embodiment, a plurality of tobacco sheets are used, but the tobacco sheets may all have the same composition or physical properties, or some or all of the tobacco sheets may have different compositions or physical properties.
The second tobacco filler may be manufactured by: a plurality of tobacco sheets having different widths are prepared, a laminate is prepared in which the width is reduced from the bottom to the top, and the laminate is rolled up and formed by a roller tube. According to the manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Further, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost tobacco sheet. In this manufacturing method, it is preferable that the laminate is prepared so that a non-contact portion is formed between the adjacent tobacco sheets after roll-forming. If there are non-contact portions (gaps) between the plurality of tobacco sheets, which are not in contact with the tobacco sheets, the flavor flow path can be ensured, and the efficiency of delivering the flavor component can be improved. On the other hand, in the case of using the tobacco product as an electrically heated tobacco product, heat from the heater can be transferred to the tobacco sheet on the outside via the contact portions of the plurality of tobacco sheets, and therefore, a high heat conduction efficiency can be ensured.
In order to provide a non-contact portion where the tobacco sheets are not in contact with each other between a plurality of tobacco sheets, for example, a method of preparing a laminate by using embossed tobacco sheets, laminating adjacent tobacco sheets so that the entire surfaces of the adjacent tobacco sheets are not adhered to each other, laminating adjacent tobacco sheets so that a part of the adjacent tobacco sheets are adhered to each other, or laminating adjacent tobacco sheets so that the entire surfaces or a part of the adjacent tobacco sheets are slightly adhered to each other so as to peel off after roll forming can be cited. In the case of preparing a smokable article including a roll paper, the roll paper may be disposed at the bottommost portion of the laminate. Further, a cylindrical mold such as a mandrel may be placed on the top of the laminate to form the second tobacco filler, and then the mold may be removed to form the fitting portion. The thickness of each tobacco sheet is not limited, but is preferably 150 μm to 1000 μm, more preferably 200 μm to 600 μm, from the viewpoint of both heat conduction efficiency and strength. The thickness of each tobacco sheet may be the same or different. The number of tobacco sheets constituting the second tobacco filler is not particularly limited, but may be, for example, 2, 3, 4, 5, 6, or 7 sheets.
(disclosure relating to roll paper)
The flavor generating article 110 may have a second roll paper 113 different from the first roll paper 112 and having at least one of a roll tubular member 114, a hollow filter 116, and a filter 115. The second roll paper 113 may also wrap a part of the first roll paper 112 around which the smokable article is wrapped. The configuration of the roll paper (hereinafter, including the first roll paper 112 or the second roll paper 113) is not particularly limited, and a general method may be used, for example, a method using pulp as a main component may be used. The pulp may be produced by mixing non-wood pulp, which is generally used for roll paper for tobacco products, such as flax pulp, hemp pulp, sisal pulp, and thatch, in addition to wood pulp, such as conifer pulp and hardwood pulp. As the type of pulp, chemical pulp, fine pulp, chemical fine pulp, and mechanical pulp by a preheating method, etc., based on kraft cooking, acidic, neutral, and alkaline sulfite cooking, sodium salt cooking, etc., can be used.
In the papermaking process using the pulp and using a fourdrinier, a cylinder machine, a short-cylinder compound machine, or the like, the paper is finished and homogenized to produce a roll paper. The paper roll may be provided with water resistance by adding a wet paper strength enhancer as necessary, or the printing state of the paper roll may be adjusted by adding a sizing agent. Further, additives for papermaking such as aluminum sulfate, various anionic, cationic, nonionic or amphoteric yield improvers, drainage improvers, papermaking additives such as paper strength improvers, dyes, pH adjusters, antifoaming agents, resin-blocking control agents, and scale adhesion inhibitors may be added.
The grammage of the roll paper base stock is, for example, generally 20gsm or more, preferably 25gsm or more. On the other hand, the grammage is generally 65gsm or less, preferably 50gsm or less, and more preferably 45gsm or less. The thickness of the roll paper having the above characteristics is not particularly limited, but is usually 10 μm or more, preferably 20 μm or more, more preferably 30 μm or more, and is usually 100 μm or less, preferably 75 μm or less, more preferably 50 μm or less, from the viewpoints of rigidity, air permeability, and ease of adjustment in paper making. The roll paper of the flavor generating article 110 may be square or rectangular in shape. In the case of using the paper as a roll for wrapping tobacco filler (for producing smokable material), the length of one side may be about 12mm to 70mm, the length of the other side may be about 15mm to 28mm, the preferable length of the other side may be about 22mm to 24mm, and the further preferable length may be about 23 mm. When the tobacco filler is wound into a cylindrical shape with the roll paper, for example, the end of the roll paper in the width direction is overlapped with the end on the opposite side by about 2mm, and the roll paper is sized, so that the shape of the paper tube becomes a cylindrical shape, and the tobacco filler is filled therein. The dimensions of the rectangular shaped roll of paper may be determined by the dimensions of the finished smokable article. When a smokable article and other members adjacent to the smokable article are connected to each other as in tipping paper and wrapped, the length of one side may be 20mm to 60mm, and the length of the other side may be 15mm to 28mm.
In addition to the pulp described above, a filler may be contained in the roll paper. The content of the filler may be 10% by weight or more and less than 60% by weight, preferably 15% by weight or more and 45% by weight or less, based on the total weight of the roll paper. In the roll paper, the filler is preferably 15 to 45 wt% in a preferable gram weight range (25 to 45 gsm). Further, the filler is preferably 15 to 45 wt% when the grammage is 25 to 35gsm, and is preferably 25 to 45 wt% when the grammage is more than 35gsm and 45 gsm. As the filler, calcium carbonate, titanium dioxide, kaolin, etc. can be used, but from the viewpoint of improving flavor, whiteness, etc., it is preferable to use calcium carbonate. In the case of such a filler-containing paper, from the viewpoint of the appearance of the roll paper used as the flavor-generating article 110, it is preferable that the paper be bright in white color and be capable of permanently retaining white color. By containing such a filler in a large amount, for example, the paper roll can have an ISO whiteness of 83% or more. In addition, from the practical viewpoint of roll paper used as the flavor-generating article 110, the first roll paper 112 and the second roll paper 113 preferably have a tensile strength of 8N/15mm or more. Thus, the roll paper is not easily broken even when the flavor generating article 110 held by the holding portion is pulled out. The tensile strength can be increased by reducing the filler content. Specifically, by making the filler content smaller than the upper limit of the filler content shown in the above-exemplified ranges of the grammage, the tensile strength can be improved.
Various auxiliaries other than the base paper and the filler may be added to the roll paper, and for example, a water resistance improver may be added to improve water resistance. The water resistance improver contains a wet paper strength improver (WS agent) and a sizing agent. Examples of the wet paper strength enhancer include urea formaldehyde resin, melamine formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of the sizing agent include rosin soaps, alkyl Ketene Dimer (AKD), alkenyl Succinic Anhydride (ASA), and highly saponified polyvinyl alcohol having a saponification degree of 90% or more. As the auxiliary agent, a paper strength enhancer may be added, and examples thereof include polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, and the like. In particular, it is known that the air permeability of oxidized starch is improved by using a very small amount (Japanese patent application laid-open No. 2017-218699). In addition, roll paper may be appropriately coated.
The coating agent may be added to at least one of the surfaces of the roll paper and the back surface. The coating agent is not particularly limited, but a coating agent capable of forming a film on the surface of paper and reducing the permeability of liquid is preferable. Examples thereof include alginic acid and salts thereof (for example, sodium salt), polysaccharides such as pectin, ethylcellulose, methylcellulose, carboxymethylcellulose, cellulose derivatives such as nitrocellulose, starch, and derivatives thereof (for example, ether derivatives such as carboxymethyl starch, hydroxyalkyl starch and cationic starch, and ester derivatives such as acetate starch, phosphate starch and octenyl succinic acid starch).
(disclosure relating to tipping paper (second roll paper 113))
The constitution of the tipping paper is not particularly limited, and may be a general one, and examples thereof include one mainly composed of pulp. The pulp may be produced by mixing non-wood pulp, which is generally used for roll paper for tobacco products, such as flax pulp, hemp pulp, sisal pulp, and thatch, in addition to wood pulp, such as conifer pulp and hardwood pulp. These pulps may be used in individual types, or may be used in combination of a plurality of types in an arbitrary ratio. The tipping paper may be one or more. As a pulp method, chemical pulp, fine pulp, chemical fine pulp, and mechanical pulp by a preheating method, etc., which are based on a kraft cooking method, an acidic, neutral, and alkaline sulfite cooking method, a sodium salt cooking method, etc., can be used. The tipping paper may be produced by a production method described later, or may be commercially available. The shape of the tipping paper is not particularly limited, and may be square or rectangular, for example.
The grammage of the tipping paper is not particularly limited, but is generally 32gsm to 40gsm, preferably 33gsm to 39gsm, and more preferably 34gsm to 38 gsm. The ventilation degree of the tipping paper is not particularly limited, but is usually 0 to 30000 g/L units, preferably more than 0 g/L units and 10000 g/L units or less. Ventilation is according to ISO 2965:2009, the differential pressure across the paper was 1kPa, using a 1cm passage area per 1 minute 2 Is a flow rate (cm) of a gas 3 ) And (3) representing. 1 gram units (1 gram units, 1 C.U.) are cm at 1kPa 3 /(min·cm 2 )。
The tipping paper may contain fillers in addition to the pulp, and examples thereof include metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide, titanium dioxide and aluminum oxide, metal sulfates such as barium sulfate and calcium sulfate, metal sulfides such as zinc sulfide, quartz, kaolin, talc, diatomaceous earth, gypsum, and the like, and in particular, calcium carbonate is preferably contained from the viewpoints of improving whiteness and opacity and increasing heating rate. In addition, 1 kind of these fillers may be used alone, or 2 or more kinds may be used in combination.
The tipping paper may contain various additives other than the pulp and filler, and may have a water resistance improver for improvement. The water resistance improver contains a wet paper strength improver (WS agent) and a sizing agent. Examples of the wet paper strength enhancer include urea formaldehyde resin, melamine formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of the sizing agent include rosin soaps, alkyl Ketene Dimer (AKD), alkenyl Succinic Anhydride (ASA), and highly saponified polyvinyl alcohol having a saponification degree of 90% or more.
The coating agent may be added to at least one of the front and back surfaces of the tipping paper. The coating agent is not particularly limited, but a coating agent capable of forming a film on the surface of paper and reducing the permeability of liquid is preferable.
The structure of the flavor generating article 110 according to the present embodiment can be used for an electrically heated tobacco product, but can also be applied to a cigarette (cigarette) accompanied by combustion. A portion of the outer surface of the tipping paper may also be covered by lip release material 117. The lip release material 117 is a material composed of: when the user engages the mouthpiece portion of the flavour generating article 110 with the mouth, the contact between the auxiliary lip and the tipping paper is not substantially adhesive but is easily separated. The lip release material 117 may also comprise ethyl cellulose, methyl cellulose, or the like, for example. For example, the outer surface of the tipping paper may be coated with the lip release material 117 by applying an ethylcellulose-based or methylcellulose-based ink to the outer surface of the tipping paper.
In this embodiment, the lip release material 117 of the tipping paper is disposed at least in a predetermined mouthpiece area that contacts the user's lips when the user engages the mouthpiece portion. More specifically, a lip release material disposition area covered with the lip release material 117 in the outer surface of the tipping paper is defined as an area located between the mouthpiece end of the mouthpiece portion and the ventilation aperture.
Next, the internal structure of the fragrance absorber 100 will be described. Fig. 3 is a cross-sectional view of the fragrance absorber 100 shown in fig. 1B, looking at 3-3. As shown in fig. 3, a mounting portion 10 for mounting objects to be stored, such as a power supply portion 20 and an atomizing portion 30, which will be described later, is provided inside an outer cover 101 of the fragrance absorber 100. The mounting portion 10 is made of, for example, a resin, and may be formed of, for example, a Polycarbonate (PC), an ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of polymers. The mounting portion 10 may include a portion made of a metal such as aluminum, for example. Here, the mounting portion 10 is preferably polycarbonate from the viewpoints of heat resistance, workability, and strength. The power supply unit 20 and the atomizing unit 30 are provided in the internal space of the placement unit 10. In addition, the power supply unit 20 and the atomizing unit 30 cannot be replaced after the fragrance absorber 100 is assembled. The outer cover 101 and the mounting portion 10 may be referred to as a frame.
The power supply unit 20 has a power supply 21. The power source 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomizing area 30. Thereby, the power supply 21 can supply power to the atomizing area 30 to appropriately heat the flavor generating article 110.
As shown in the drawing, the atomizing area 30 includes a chamber 50 (corresponding to an example of a housing area) extending in the direction of insertion (Z-axis direction) of the flavor generating article 110, a heating area 40 disposed in the axial direction (Z-axis direction) of the chamber 50 and covering a part of the chamber 50, a heat insulating area 32, and a substantially cylindrical insertion guide member 34. The chamber 50 is configured to receive a flavour generating article 110. A projection (not shown) (corresponding to a grip portion, an example of which is a projection) for gripping the stored flavor-generating article 110 is provided on the inner peripheral surface of the chamber 50. The protrusions are described in detail later.
The heating unit 40 is configured to contact the outer peripheral surface of the chamber 50 and heat the flavor generating article 110 stored in the chamber 50. Here, the heating section 40 does not have a heating element inserted into the flavor generating article 110. As shown, a bottom member 36 may be provided at the bottom of the chamber 50. The base member 36 may function as a stop for positioning the flavor-generating article 110 inserted into the chamber 50. The base member 36 may have irregularities on the surface against which the flavor-generating article 110 abuts, and may divide a space capable of supplying air on the surface against which the flavor-generating article 110 abuts. The base member 36 is made of, for example, a resin, and may be made of, for example, a Polycarbonate (PC), an ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone) or a polymer alloy containing a plurality of polymers, or a metal such as aluminum. In addition, the base member 36 is preferably formed of a material having a low thermal conductivity in order to suppress heat transfer to the heat insulating portion 32 and the like.
The heat insulating portion 32 is generally cylindrical in shape as a whole, and is disposed so as to cover the chamber 50. The insulation 32 may comprise aerogel sheets, for example. The insertion guide member 34 is provided between the outer shroud 101 and the chamber 50. The insertion guide member 34 is configured such that, when inserted into the housing from the opening of the outer cover 101, the claws engage with the housing and cannot be disengaged from the housing. The insertion guide member 34 is made of, for example, a resin, and may be formed of, for example, a Polycarbonate (PC), an ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), or a polymer alloy containing a plurality of polymers. The insertion guide member 34 may be made of metal, glass, ceramic, or the like. In addition, from the viewpoint of heat resistance, the insertion guide member 34 is preferably PEEK. The insertion guide member 34 communicates with the outside of the fragrance absorber 100 when the slide cover 102 is in the open position, and the fragrance generating article 110 is inserted into the through hole 34a of the insertion guide member 34, thereby guiding the insertion of the fragrance generating article 110 into the chamber 50. The slide cover 102 is configured to expose the through hole 34a of the insertion guide member 34 to the outside and to cover at least a part of the insertion guide member 34 in the axial direction (Z-axis direction) of the chamber 50 when in the open position. In fig. 3, the slide cover 102 is shown by a two-dot chain line in a state of being entirely closed to cover the through hole 34a of the insertion guide member 34.
The fragrance absorber 100 further has a first holding portion 37 and a second holding portion 38 that hold both ends of the chamber 50 and the heat insulating portion 32. The first holding portion 37 is configured to hold the chamber 50 and an end portion of the heat insulating portion 32 on the negative Z-axis side. The second holding portion 38 is configured to hold the chamber 50 and an end portion of the heat insulating portion 32 on the sliding cover 102 side (Z-axis positive direction side).
Next, the structure of the chamber 50 will be described. Fig. 4A is a perspective view of the chamber 50 of the present embodiment. Fig. 4B is a cross-sectional view of the chamber 50 shown in fig. 4A looking at 4B-4B. Fig. 5A is a cross-sectional view of chamber 50 of fig. 4B looking at 5A-5A. Fig. 5B is a cross-sectional view of the chamber 50 shown in fig. 4B looking toward fig. 5B-5B. Fig. 6 is a perspective view of the chamber 50 and the heating unit 40 according to the present embodiment.
As shown in fig. 4A and 4B, the chamber 50 may have a cylindrical shape including the opening 52 into which the fragrance generating article 110 is inserted and the cylindrical side wall portion 60 which accommodates the fragrance generating article 110. A flange portion 52a is formed at an end of the opening 52 that partitions the chamber 50. The chamber 50 is arranged such that the flange portion 52a provided on the opposite side of the bottom portion 56 is open to the outer shroud 101. The chamber 50 is preferably formed of a material having heat resistance and a small thermal expansion coefficient, and may be formed of stainless steel or the like, for example. In addition to metal, the chamber 50 may be formed of a resin such as PEEK, glass, or ceramic. This allows the fragrance generating article 110 to be efficiently heated from the chamber 50. The chamber 50 is not limited to a cylindrical shape, and may have a cup shape.
As shown in fig. 4B and 5B, the side wall portion 60 includes a contact portion 62 and a separation portion 66. When the flavor-generating article 110 is disposed at a desired position in the chamber 50, the contact portion 62 contacts or presses a part of the flavor-generating article 110 in the axial direction (Z-axis direction) of the chamber 50, and the separation portion 66 is separated from the flavor-generating article 110. That is, the chamber 50 compresses the inserted flavor generating article 110 and holds it. In the present specification, the "desired position in the chamber 50" refers to a position where the flavor generating article 110 is appropriately heated or a position of the flavor generating article 110 when the user smokes. The contact portion 62 has an inner surface 62a and an outer surface 62b. The separator 66 has an inner surface 66a and an outer surface 66b. As shown in fig. 6, the heating portion 40 is disposed on the outer surface 62b of the contact portion 62. The heating portion 40 is preferably disposed on the outer surface 62b of the contact portion 62 without any gap. The heating portion 40 may include an adhesive layer. In this case, it is preferable that the heating portion 40 including the adhesive layer is disposed on the outer surface 62b of the contact portion 62 without a gap.
As shown in fig. 4A and 5B, the outer surface 62B of the contact portion 62 is a plane. By making the outer surface 62b of the contact portion 62 flat, as shown in fig. 6, when the band-shaped electrode 48 is connected to the heating portion 40 disposed on the outer surface 62b of the contact portion 62, the band-shaped electrode 48 can be prevented from being deflected. As shown in fig. 4B and 5B, the inner surface 62a of the contact portion 62 is a plane. As shown in fig. 4B and 5B, the contact portion 62 has a uniform thickness.
As shown in fig. 4A, 4B, and 5B, the chamber 50 has two contact portions 62 in the circumferential direction of the chamber 50, and the two contact portions 62 are opposed in parallel to each other. At least a portion of the distance between the inner surfaces 62a of the two contact portions 62 is preferably smaller than the width of the portion of the flavor-generating article 110 inserted into the chamber 50 that is disposed between the contact portions 62.
As shown in fig. 5B, the inner surface 66a of the separation portion 66 may have an overall circular arc-shaped cross section on a cross section orthogonal to the axial direction (Z-axis direction) of the chamber 50. In addition, the separation portion 66 is arranged adjacent to the contact portion 62 in the circumferential direction. That is, the contact portion 62 and the separation portion 66 form a non-circular inner peripheral surface on a cross section orthogonal to the axial direction (Z-axis direction) of the chamber 50.
As shown in fig. 4B, the chamber 50 may have a hole 56a in its bottom 56 so that the bottom member 36 shown in fig. 3 is disposed inside the chamber 50 therethrough. The bottom member 36 may be secured to the interior of the bottom 56 of the chamber 50 by an adhesive or the like. The adhesive interposed between the bottom member 36 and the bottom portion 56 may be made of a resin material such as epoxy resin. Instead of this, an inorganic adhesive such as cement or welding may be used. The base member 36 provided at the base 56 may support a portion of the flavor-generating article 110 inserted into the chamber 50 so as to expose at least a portion of the end surface of the flavor-generating article 110. The bottom 56 may support a part of the fragrance generating article 110 so that the end surface of the exposed fragrance generating article 110 communicates with a gap 67 (see fig. 7) described later.
As shown in fig. 4A, 4B, and 5A, the chamber 50 preferably has a cylindrical non-holding portion 54 between the opening 52 and the side wall portion 60. In a state where the fragrance generating article 110 is positioned at a desired position of the chamber 50, a gap may be formed between the non-holding portion 54 and the fragrance generating article 110. As shown in fig. 4A and 4B, the chamber 50 preferably has a first guide portion 58, and the first guide portion 58 preferably has a tapered surface 58a connecting the inner surface of the non-holding portion 54 and the inner surface 62a of the contact portion 62.
As shown in fig. 6, the heating portion 40 has a heating element 42. The heating element 42 may also be, for example, a heat generating resistor. The heating element 42 is preferably configured to heat the contact portion 62 without contacting the separation portion 66 of the chamber 50. In other words, the heating element 42 is preferably disposed only on the outer surface of the contact portion 62. The heating element 42 may also have a difference in heating capacity between the portion that heats the separating portion 66 of the chamber 50 and the portion that heats the contacting portion 62. Specifically, the heating element 42 may also be configured to heat the contact portion 62 to a higher temperature than the separation portion 66. For example, the arrangement density of the heating resistors of the heating element 42 in the contact portion 62 and the separation portion 66 may be adjusted. The heating element 42 may be wound around the outer periphery of the chamber 50 so as to have substantially the same heating capacity over the entire periphery of the chamber 50. As shown in fig. 6, the heating portion 40 preferably has an electric insulating member 44 made of resin or the like covering at least one surface of the heating element 42 in addition to the heating element 42. In the present embodiment, the electric insulation member 44 is arranged to cover both sides of the heating element 42.
Fig. 7 is a cross-sectional view of fig. 5B showing a state in which a flavor generating article 110 is disposed at a desired position in the chamber 50 according to the present embodiment. As shown in fig. 7, when the flavor generating article 110 is disposed at a desired position in the chamber 50, the flavor generating article 110 can be pressed in contact with the contact portion 62 of the chamber 50. On the other hand, a space 67 is formed between the flavor generating article 110 and the separating portion 66. Void 67 may be in communication with opening 52 of chamber 50 and an end face of a scent generating article 110 positioned within chamber 50. Thus, the air flowing in from the opening 52 of the chamber 50 can flow into the interior of the flavor generating article 110 through the void 67. In other words, an air flow path (gap 67) is formed between the flavor generating article 110 and the separating section 66.
Next, a specific structure of the protrusions corresponding to each example will be described with respect to the chamber 50 of the present embodiment.
Example 1: lengthwise protrusions
Fig. 8 is a cross-sectional view showing the chamber 50 of example 1 of the present embodiment. Fig. 9 is a cross-sectional view of the chamber 50 shown in fig. 8. Here, fig. 8 shows a section of the chamber 50 taken along the axis of the chamber 50, and is a section orthogonal to the section shown in fig. 4B. Fig. 9 shows a cross section corresponding to fig. 5A.
As shown in fig. 8 and 9, a protrusion 51A is formed on the inner peripheral surface of the chamber 50, and the protrusion 51A is configured to press and hold the outer peripheral surface of the flavor-generating article 110 accommodated in the chamber 50 toward the inside in the radial direction of the chamber 50. The protrusion 51A is provided on the inner peripheral surface of the chamber 50 on the inner surface 62a of the contact portion 62. Further, the protrusions 51A are provided on the inner surfaces 62a facing each other. The protrusion 51A protrudes from the inner peripheral surface of the chamber 50 and presses the flavor generating article 110, and extends in the axial direction (Z-axis direction) of the chamber 50. The protrusion 51A may be formed by embossing or may be formed by a convex member attached to the inner peripheral surface of the chamber 50. The projections 51A may be provided on only one of the inner surfaces 62a facing each other, or a plurality of projections 51A may be provided on one inner surface 62a.
In this way, by providing the projections 51A on the inner surface 62a of the contact portion 62, the flavor-generating article 110 can be compressed and held in the chamber 50, while the flavor-generating article 110 is held by the projections 51A in the chamber 50. Therefore, even when stress is applied to the flavor generating article 110, the flavor generating article 110 can be prevented from being detached from the chamber 50. Further, by forming the projection 51A with a projection extending in the axial direction (Z-axis direction) of the chamber 50, the flavor generating article 110 can be stably held in the chamber 50.
The protrusion 51A is provided at a position that can be brought into contact with at least two portions of the filling portion 111, the tubular member 114, and the filter portion 115 of the flavor-generating article 110 when the flavor-generating article 110 is inserted into the chamber 50. For example, when the flavor generating article 110 is inserted into the chamber 50, the protrusion 51A first contacts the filling portion 111, and then contacts the tubular member 114 and the filter portion 115. Therefore, the flavor generating article 110 can be held stably at a position near the insertion end of the chamber 50.
Example 2: transverse long protrusion
Fig. 10 is a cross-sectional view showing a chamber 50 of example 2 of the present embodiment. Fig. 11 is a cross-sectional view of the chamber 50 shown in fig. 10. Here, fig. 10 shows a section of the chamber 50 taken along the axis of the chamber 50, and is a section orthogonal to the section shown in fig. 4B. Fig. 11 shows a cross section corresponding to fig. 5A.
As shown in fig. 10 and 11, a protrusion 51B is formed on the inner peripheral surface of the chamber 50, and the protrusion 51B is configured to press and hold the outer peripheral surface of the flavor-generating article 110 accommodated in the chamber 50 toward the inside in the radial direction of the chamber 50. The protrusion 51B is provided on the inner peripheral surface of the chamber 50 on the inner surface 62a of the contact portion 62. Further, the protrusions 51B are provided on the inner surfaces 62a facing each other. The protrusion 51B protrudes from the inner peripheral surface of the chamber 50 and presses the flavor generating article 110, and extends in a direction orthogonal to the axial direction (Z-axis direction) of the chamber 50, specifically, in the lateral direction (Y-axis direction). The protrusions 51B may be formed by embossing, or may be formed by a convex member attached to the inner peripheral surface of the chamber 50, as in embodiment 1. The projections 51B may be provided on only one of the inner surfaces 62a facing each other, or a plurality of projections 51B may be provided on one inner surface 62a.
In this way, by providing the projections 51B on the inner surface 62a of the contact portion 62, the flavor-generating article 110 can be compressed and held in the chamber 50, while the flavor-generating article 110 is held by the projections 51B in the chamber 50. Therefore, even when stress is applied to the flavor generating article 110, the flavor generating article 110 can be prevented from being detached from the chamber 50. Further, by forming the protrusion 51B with a protrusion extending in the lateral direction (Y-axis direction) of the chamber 50, rotation of the flavor-generating article 110 about the Y-axis can be restricted, and therefore, shake of the flavor-generating article 110 toward the separation portion 66 side can be suppressed.
In addition, as in embodiment 1, by providing the projection 51B at a position where it can be brought into contact with at least two portions of the flavor-generating article 110, the flavor-generating article 110 can be held stably at a position near the insertion end of the chamber 50.
Example 3: dot-shaped protrusion
Fig. 12 is a cross-sectional view showing the chamber 50 of example 3 of the present embodiment. Fig. 13 is a cross-sectional view of the chamber 50 shown in fig. 12. Here, fig. 12 shows a section of the chamber 50 taken along the axis of the chamber 50, and is a section orthogonal to the section shown in fig. 4B. Fig. 13 shows a cross section corresponding to fig. 5A.
As shown in fig. 12 and 13, a protrusion 51C is formed on the inner peripheral surface of the chamber 50, and the protrusion 51C is configured to press and hold the outer peripheral surface of the flavor-generating article 110 accommodated in the chamber 50 toward the inside in the radial direction of the chamber 50. The protrusion 51C is provided on the inner peripheral surface of the chamber 50 on the inner surface 62a of the contact portion 62. Further, the protrusions 51C are provided on the inner surfaces 62a facing each other. The projections 51C are dot-like projections protruding from the inner peripheral surface of the chamber 50 and pressing the flavor generating article 110. The protrusions 51C may be formed by embossing, or may be formed by a convex member attached to the inner peripheral surface of the chamber 50, as in embodiment 1. The projections 51C may be provided on only one of the inner surfaces 62a facing each other, or a plurality of projections 51C may be provided on one inner surface 62a.
In this way, by providing the projections 51C on the inner surface 62a of the contact portion 62, the flavor-generating article 110 can be compressed and held in the chamber 50, while the flavor-generating article 110 is gripped by the projections 51C in the chamber 50. Therefore, even when stress is applied to the flavor generating article 110, the flavor generating article 110 can be prevented from being detached from the chamber 50. Further, by forming the projections 51C with dot-like projections, the flavor-generating article 110 can be pressed and held in the chamber 50 with a simple configuration.
In addition, as in embodiment 1, by providing the projection 51C at a position where it can be brought into contact with at least two portions of the flavor-generating article 110, the flavor-generating article 110 can be held stably at a position near the insertion end of the chamber 50.
[ experimental results ]
Various experiments were performed using the flavor pickups using the chambers 50 of examples 1 to 3 and the flavor pickups of comparative examples 1 to 3 according to the present embodiment described above. The experimental results are described below.
[ preparation of sample ]
First, a smoking system comprising a combination of a flavor-generating article and a flavor inhaler shown in table 1 was prepared. Here, the test aspirator 1 of the sample 1 has the chamber 50 of the above-described embodiment 1 (refer to fig. 8 and 9). The test aspirator 2 for the sample 2 was the same as the sample 1 except for having the chamber 50 (see fig. 10 and 11) of the above-described example 2. The test aspirator 3 for the sample 3 was the same as the sample 1 except for having the chamber 50 (see fig. 12 and 13) of the above-described example 3.
The flavor pickups of samples 4 to 6 were PLoomS2.0, PLoom, and glo super (glo is a registered trademark) which are commercially available products, respectively. The flavor generating articles in samples 1 to 5 were produced as exclusive articles for test pickups 1 to 3, plooms2.0, and plom (sold in russia, UK). In addition, the flavor generating article in sample 6 was a commercially available product dedicated to glo super.
Here, the relation between the flavor generating articles in the samples 1 to 3 and the test pickups 1 to 3 corresponds to, for example, a combination of a consumable and a device kit. The composition comprises a consumable containing a flavor-generating article in samples 1 to 3 and a device set containing any one of test pickups 1 to 3 in samples 1 to 3, wherein at least one of the consumable and the device set has a display indicating use in the other of the consumable and the device set. That is, the consumable is a special article of the device kit. The display includes, for example, "X", "for X", and "designed for X" (X is a brand name, a trade name, or the like). The consumable product includes a package of the consumable product, and the device package includes, for example, a package and an operation instruction.
TABLE 1
[ method for measuring resistance value ]
For each sample, the resistance value (insertion resistance) when the flavor generating article was inserted into the flavor inhaler was measured using EZ-S500N (hereinafter also referred to as "apparatus") manufactured by Shimadzu corporation. Specifically, first, the fragrance absorber is mounted on a fragrance absorber holder mounted on the device. Next, one end portion of the flavor generating article (the end portion other than the mouthpiece portion side) is inserted into the flavor inhaler to such an extent that the flavor generating article does not shake. Next, the press-fitting jig is brought into contact with the other end portion (the end portion on the mouthpiece portion side) of the flavor generating article. Next, zero point correction of the resistance value of the device is performed.
Then, it was confirmed that the flavor inhaler and the flavor generating article were not tilted, and the press-fit jig was lowered. The stroke speed of the press-in jig at this time was set to 60mm/min. In addition, the temperature was 25℃and the humidity was 20% as test conditions. In this device, the sampling length is set to 50msec, and in this case, the length of one section of acquired data is set to 0.05mm. Next, the press-fitting jig was lowered by a predetermined length, and after the operation of the press-fitting jig was stopped, the test was ended. In each sample, the above-described measurement was performed twice.
[ obtaining resistance value ]
The average value of the results of the two measurements performed on each sample was set as the resistance value. In this case, first, the position at which the tip of the flavor-generating article reaches the end position of the chamber is determined for each measurement result, and the two measurement results are prepared based on the determined position, and an average value is obtained. Then, each value was obtained for a range of 10mm from the end position of the chamber. That is, the insertion force, average resistance, local resistance position, and minimum resistance described later are obtained within a range of 10mm from the end position of the chamber.
Fig. 14 to 19 are graphs showing the relationship between the distance (mm) from the end position of the chamber and the measured resistance value (N) in each of samples 1 to 6. In fig. 14 to 19, the position of the press-fit jig corresponding to the end position of the chamber is shown as 0, the position before reaching the end position is shown as a positive value, and the position after reaching the end position is shown as a negative value. For example, the position +10mm in FIGS. 14 to 19 refers to a position 10mm before the end position in the insertion direction of the flavor generating article.
Here, the "position at the time of reaching the end position of the chamber" (hereinafter, also referred to as the end position) is set to a position of a section immediately before a certain section among the resistance values measured by the above-described method, when a section having a resistance value of 0.1N or more has a continuous 0.5mm section (i.e., a difference between resistance values of 0.05 mm).
[ insertion force ]
Based on the data of the resistance value obtained by the above method, the insertion force of each sample was obtained. Here, the insertion force means a resistance value when the front end of the flavor generating article reaches the end position of the chamber.
[ average resistance ]
Based on the data of the resistance values obtained by the above-described method, the average resistance of each sample was obtained. Here, the first half average resistance and the second half average resistance were evaluated. The first half average resistance means an average value of resistance values in a range of 10mm to 5mm from the tip end position, and the second half average resistance means an average value of resistance values in a range of 5mm to 0mm from the tip end position. In addition, the ratio of the second half average resistance to the first half average resistance (second half/first half) is also referred to as a first resistance ratio.
[ local resistance and local resistance position ]
Based on the data of the resistance values obtained by the above-described method, the local resistance and the local resistance position of each sample are obtained. Here, the local resistance means the maximum resistance value in a local fluctuation region in which the resistance value fluctuates by a predetermined amount or more within a predetermined range, specifically, in a region between the first local rise and the last local fall when there is a local rise and a local fall in sequence in a continuous range of 1.0 mm. The local increase means an increase in resistance value of 0.1N or more in 2 consecutive sections. The local decrease means a decrease in resistance value of 0.05N or more in 2 consecutive intervals. In addition, the ratio of the local resistance to the insertion force is referred to as a second resistance ratio. The local resistance position is a position from the end position of the chamber, that is, a distance from the end position of the chamber to the position where the local resistance is generated when the local resistance is generated.
[ minimum resistance ]
Based on the data of the resistance value obtained by the above method, the minimum resistance of each sample was obtained. Here, the minimum resistance refers to a minimum resistance value between the local resistance position and the end position of the chamber.
The insertion force, average resistance, local resistance position, and minimum resistance obtained for each of samples 1 to 6 are shown in table 2.
TABLE 2
Sensory evaluation
Sensory evaluation was made by 5 panelists with trained recognition capability as to whether the end of the chamber had been easily perceived and whether it was easily predicted to be reached when inserting the fragrance-generating article into the chamber for each of samples 1 to 6. In addition, it is also easy to perceive that the end that has reached the chamber is referred to as obtaining an end arrival sense, and it is also easy to anticipate that the end that will reach the chamber is referred to as obtaining an end arrival anticipation sense.
Sensory evaluation of sample 6
First, regarding the end arrival sense, 5 panelists used sample 6, and the degree to which the front end of the flavor-generating article was perceived to have reached the end of the chamber was evaluated by the panelist's objection. The evaluation criteria are as follows.
It is difficult to feel the arrival of the tip.
The arrival of the tip can be perceived.
Next, regarding the end arrival prediction sense, 5 panelists used the sample 6, and the degree to which the front end of the fragrance-generating article could be predicted to reach the end of the chamber was evaluated by the panelist's objection. The evaluation criteria are as follows.
It is difficult to predict the arrival of the end.
The arrival of the end can be foreseen.
The evaluation results after the conclusions of the panelists revealed that the sample 6 easily perceived that the front end of the flavor-generating article had reached the end of the chamber, and on the other hand, it was difficult to predict that the front end of the flavor-generating article was about to reach the end of the chamber.
[ sensory evaluation of samples 1 to 5 ]
Next, regarding the end-of-line feeling, the same 5 panelists used samples 1 to 5, and the degree to which the front end of the flavor-generating article was perceived to have reached the end of the chamber was independently scored by 5-stage evaluations of 1 to 5 points with sample 6 being 3 points, and the average value was calculated. The evaluation criteria are as follows.

1, the method comprises the following steps: it is difficult to feel the arrival of the tip.
Next, regarding the end-reached prediction feeling, the same 5 panelists used samples 1 to 5, and the degree to which the front end of the predictable flavor-generating article was about to reach the end of the chamber was independently scored by 5-stage evaluations of 1 to 5 points with the sample 6 being 3 points, and the average value was calculated. The evaluation criteria are as follows.
5, the method comprises the following steps: the arrival of the end is easily foreseen.
4, the following steps: the arrival of the tip is somewhat easier to predict.
3, the method comprises the following steps: there is no change.
2, the method comprises the following steps: it is slightly difficult to predict the arrival of the tip.
1, the method comprises the following steps: it is difficult to predict the arrival of the terminal.
The results of evaluating the sense of end arrival and the sense of end arrival prediction for each of samples 1 to 6 are shown in table 3.
TABLE 3
| Sample No. | Sense of arrival of end | End-of-arrival prediction |
| Sample 1 | 3.3 | 3.5 |
| Sample 2 | 4 | 4.8 |
| Sample 3 | 4.1 | 4.9 |
| Sample 4 | 2.3 | 3.4 |
| Sample 5 | 1 | 1.4 |
| Sample 6 | 3 | 3 |
[ study of results ]
As shown in table 2, since the insertion force of samples 1 to 3 was 4.00N or less, it was felt that the end of the chamber had been reached when the flavor generating article was inserted into the chamber. In addition, since the first resistance ratio of samples 1 to 3 is larger than 1.0, the rising sense of the insertion resistance at the side close to the end of the chamber makes the approach of the end perceived, and therefore it is easy to predict that the end of the chamber will be reached. Further, since the samples 1 to 3 are provided with the local fluctuation range, the user can easily perceive the approach of the end of the chamber, and can more easily predict that the end of the chamber is to be reached.
In fact, as shown in Table 3, the evaluation of the end-of-arrival feeling and the end-of-arrival prediction feeling of each of samples 1 to 3 exceeded 3 minutes. Therefore, samples 1 to 3 were confirmed to have both the sense of arrival at the end and the sense of arrival at the end, that is, the sense of arrival at the end and the sense of arrival at the end. This is considered to be because, in samples 1 to 3, the flavor-generating article is less resistant to insertion, and thus the end-of-line sensation is easily obtained. In addition, in sample 2, as shown in fig. 15, it is considered that the end arrival sensation is more easily obtained because the decrease in the resistance value is perceived after the increase in the resistance value in the local fluctuation range. In samples 1 to 3, it is considered that the end of the chamber was perceived to be reached by pressing the fragrance-generating article once again after the fragrance-generating article was inserted, and thus the end-reached feeling was easily obtained.
In addition, as the lower limit value of the insertion force, from the viewpoint of suppressing the falling off of the flavor-generating article, it is preferably 0.50N or more, more preferably 0.70N or more, and still more preferably 1.00N or more. In addition, the upper limit value of the insertion force is preferably 3.00N or less, more preferably 2.00N or less, from the viewpoint of easy insertion. In addition, from the viewpoint of easily obtaining a sense of anticipation of the end, the lower limit value of the first resistance ratio is preferably 1.0 or more, more preferably 1.05 or more. The upper limit value of the first resistance ratio is preferably 2.0 or less, more preferably 1.8 or less.
As shown in table 2, since the second resistance ratio, which is the ratio of the resistance value in the local fluctuation range to the insertion force, is 0.8 or more, the resistance value in the local fluctuation range is significantly smaller than the insertion force, and thus, it is possible to suppress the foresight condition that does not contribute to reaching the end of the chamber.
In fact, as shown in Table 3, the evaluation of the end-of-arrival feeling and the end-of-arrival prediction feeling of each of samples 2 and 3 was more than 4 points. Therefore, it was confirmed that both samples 2 and 3 obtained both the sense of end arrival and the sense of end arrival prediction, and in particular, a higher sense of end arrival prediction was obtained. This is considered to be because, referring to fig. 14 to 16, in samples 2 and 3, after the fragrance-generating article is inserted, the resistance value is smaller than that of sample 1, and thus the end-of-fragrance-generating article can more easily reach the expected feeling.
The upper limit value of the second resistance ratio is preferably 1.0 or less. If the local fluctuation range has a resistance value larger than the insertion force, there is a risk of giving a user a sense of discomfort, and there is a risk of the user misidentifying the local fluctuation range as the end position of the chamber. If there is an excessively large local resistance value, there is a risk that the fragrance may cause buckling of the article in the local fluctuation range. In view of the fact that the user is expected to reach the distal end by the local resistance, the lower limit value of the second resistance ratio is preferably 0.8 or more, more preferably 0.9 or more.
Further, as shown in table 2, since the distance from the end position of the chamber to the local fluctuation zone is 5.0mm or less, the user can maintain the sense of passing through the local fluctuation zone until reaching the end of the chamber, and thus it is easier to predict that the end of the chamber is about to be reached.
In fact, as shown in table 3, the evaluation of the end arrival sensation and the end arrival prediction sensation of sample 3 was the greatest among samples 1 to 3. Therefore, it was confirmed that the sample 3 obtained both the sense of arrival of the end and the sense of arrival of the end, and in particular, the sense of arrival of the end was extremely high.
The upper limit value of the distance from the end position of the chamber to the local fluctuation zone is preferably 6.5mm or less, more preferably 6.0mm or less. In addition, from the viewpoint of suppressing the arrival of the user at the end of the chamber before the end position of the chamber approaches the local fluctuation zone and the user obtains the sense of passing through the local fluctuation zone, the lower limit value of the distance from the end position of the chamber to the local fluctuation zone is preferably 2.0mm or more, more preferably 3.0mm or more, and even more preferably 3.5mm or more.
On the other hand, since the insertion force of the samples 4, 5 is large, it is difficult to feel that the front end of the flavor generating article has reached the end of the chamber, and it is difficult to predict that it will reach the end of the chamber. In addition, as described above, although the sample 6 can feel that the front end of the flavor generating article has reached the end of the chamber, it is difficult to predict that the front end of the flavor generating article will reach the end of the chamber.
The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications are possible within the scope of the technical ideas described in the claims, the specification, and the drawings. Any shape and material not directly described in the specification and drawings fall within the scope of the technical idea of the present application as long as the function and effect of the present application are achieved.
For example, the flavor inhaler 100 of the present embodiment has a so-called countercurrent air flow path for supplying air flowing in from the opening 52 of the chamber 50 to the end surface of the flavor generating article 110, but the present invention is not limited to this, and may have a so-called underflow air flow path for supplying air from the bottom 56 of the chamber 50 into the chamber 50. The heating element 42 is not limited to the resistance heating type, and may be an induction heating type. In this case, the heating element 42 is capable of heating the chamber 50 by induction heating. The flavor generating article 110 may have a heat sensitive body as a heating element. In this case, the flavor inhaler 100 does not have a heating element inserted into the flavor generating article, and a heat sensing body as the heating element is present inside the flavor generating article 110. Although the structure in which the heating element 42 is disposed around the chamber 50 to heat the flavor-generating article 110 in the chamber 50 has been described, the method of heating the flavor-generating article 110 in the chamber 50 may be such that the heating element 42 is in direct contact with the flavor-generating article 110 or frictional heat is generated by vibration of substances in the flavor-generating article 110.
