[Patent Document 1] Specification of Japanese Patent No. 6737902

In cited document 1, a structure for holding a scent product inserted into a cavity is disclosed. However, there is no device that can easily feel that the end of the cavity has been reached and can easily predict that the scent product has reached the end of the cavity when the scent product is inserted into the cavity. That is, since it is not easy to feel that the end of the cavity has been reached and it is difficult to predict that the end of the cavity has been reached, the scent product may be over-pressed, which may cause deformation of the scent product.

In addition, if the aroma product is not placed in a proper position relative to the heating part of the aroma inhaler, the aroma product (especially the filling part filled with smokable substances) will not be heated sufficiently, which may sometimes have an undesirable effect on the aroma. Therefore, it is important to be able to place the aroma product in a proper position in the chamber so that it is easy to feel that the end of the chamber has been reached and it is easy to foresee that the end of the chamber has been reached.

The present invention is developed to solve at least part of the above-mentioned problems, and its purpose is to obtain a smoking system that can easily feel that the end of the chamber has been reached and can easily foresee that the end of the chamber has been reached when the aroma product is inserted into the chamber.

In the first form of the present invention, a smoking system is provided. The smoking system comprises a flavor inhaler and a flavor product; the flavor inhaler comprises: a receiving portion having an opening formed at one end and receiving at least a portion of the flavor product through the opening; the flavor product is inserted into the receiving portion, and the resistance value when the front end of the flavor product reaches the end of the receiving portion is set as the insertion force A; when the flavor product is inserted into the receiving portion, the average of the resistance values from the middle point between the predetermined position on the insertion end side of the receiving portion and the end of the receiving portion to the end of the receiving portion, i.e., the average resistance of the second half, is set to the ratio of the average of the resistance values from the predetermined position to the middle point between the predetermined position and the end of the receiving portion, i.e., the average resistance of the first half, to the ratio of the resistance values from the predetermined position to the middle point between the predetermined position and the end of the receiving portion, i.e., the average resistance of the first half, as the first resistance ratio B, and the following formula (1) and the following formula (2) are satisfied.

A≦4.00N‧‧‧(1)

B>1.0‧‧‧(2)

According to the first embodiment of the present invention, by satisfying formula (1), when inserting the fragrance product into the storage part, one can feel that the end of the storage part has been reached. In addition, by satisfying formula (2), the rising feeling of the insertion resistance on one side close to the end of the storage part can make people feel the approach of the end, and it is easy to foresee that the end of the storage part has been reached.

In the first form of the present invention, the predetermined position of the insertion end side of the receiving portion may be a position 10 mm away from the end of the receiving portion. In addition, the midpoint between the predetermined position and the end of the receiving portion may be a position 5 mm away from the end of the receiving portion. In this case, the so-called average resistance of the front half may be the average of the resistance values in the range of 10 mm to 5 mm from the end of the receiving portion, and the so-called average resistance of the rear half may be the average of the resistance values in the range of 5 mm to 0 mm from the end of the receiving portion.

In the second form of the present invention, in the first form, when the fragrance product is inserted into the storage portion, at least one local change area is provided in the predetermined range where the resistance value changes by more than a predetermined amount.

According to the second embodiment of the present invention, by providing a local change in the resistance value, the user can easily feel the approach of the end of the storage portion and more easily foresee reaching the end of the storage portion.

In the third form of the present invention, when the ratio of the resistance value in the local variation area to the insertion force is set to the second resistance ratio C in the second form, the following formula (3) is satisfied.

C≧0.8‧‧‧(3)

According to the third aspect of the present invention, by satisfying formula (3), since the resistance value in the local variation area is significantly smaller than the insertion force, the inability to foresee reaching the end of the chamber can be suppressed.

In the fourth form of the present invention, when the distance from the end position of the accommodating portion to the local variable area is set to distance D in the second or third form, the following formula (4) is satisfied.

D≦5.0mm‧‧‧(4)

According to the fourth aspect of the present invention, by satisfying formula (4), until reaching the end of the storage portion, the user can maintain the feeling of having passed through the local variable area, and it becomes easier to foresee reaching the end of the storage portion.

In the fifth aspect of the present invention, in any aspect of the first to fourth aspects, the smoking system further comprises a heating unit for heating the aroma-producing product contained in the containing unit; wherein the heating unit is disposed in the aroma inhaler and does not have a heating element to be inserted into the aroma-producing product.

According to the ninth aspect of the present invention, when the fragrance inhaler used for the fragrance product is applied to the fragrance product included in the consumables, it is easy to feel that the end of the storage part has been reached, and it is easy to foresee that the end of the storage part has been reached.

In the 10th form of the present invention, a combination of a consumable and a device set is provided. The combination comprises: a consumable comprising a fragrance producing product as described in any one of the 1st to 6th forms, and a device set comprising a fragrance inhaler as described in any one of the 1st to 6th forms; wherein at least one of the consumable and the device set has a mark indicating that it is to be used in the other of the consumable and the device set.

According to the tenth aspect of the present invention, in the combination of the device set and the consumables that are dedicated to the device set, it is easy to feel that the end of the storage section has been reached, and it is easy to foresee that the end of the storage section has been reached.

In the eleventh aspect of the present invention, a method is provided for obtaining a feeling of final arrival and a feeling of foreseeing final arrival in a smoking system having a flavor inhaler and a flavor producing product. In this method, the aroma inhaler includes: a receiving portion having an opening formed at one end and receiving at least a portion of the aroma product through the opening; inserting the aroma product into the receiving portion, and setting the resistance value when the front end of the aroma product reaches the end of the receiving portion as the insertion force A; when the aroma product is inserted into the receiving portion, the average of the resistance values from the middle point between the predetermined position and the end of the receiving portion to the end of the receiving portion, i.e., the average resistance of the second half, relative to the average of the resistance values from the predetermined position on the insertion end side of the receiving portion to the middle point between the predetermined position and the end of the receiving portion, i.e., the average resistance of the first half, is set as the ratio of the resistance values from the predetermined position on the insertion end side of the receiving portion to the middle point between the predetermined position and the end of the receiving portion, i.e., the average resistance of the first half, to satisfy the following formula (1) and the following formula (2).

A≦4.00N‧‧‧(1)

The following is a description of the implementation of the present invention with reference to the drawings. In the drawings described below, the same or corresponding components are given the same symbols and repeated descriptions are omitted.

[Basic structure]

First, the basic structure of the fragrance inhaler of the present embodiment is described. FIG. 1A is a schematic front view of the fragrance inhaler of the present embodiment. FIG. 1B is a schematic top view of the fragrance inhaler of the present embodiment. FIG. 1C is a schematic bottom view of the fragrance inhaler of the present embodiment. For the sake of simplicity in explanation, an X-Y-Z orthogonal coordinate system is added to the drawings described in this manual. In this coordinate system, the Z axis is facing straight upward, the X-Y plane is configured in a manner that cuts the fragrance inhaler 100 in the horizontal direction, and the Y axis is configured in a manner that extends from the front to the back of the fragrance inhaler 100. The Z axis is the insertion direction of the fragrance product contained in the chamber 50 of the atomization section 30 described later, or it can also be called the axial direction of the chamber 50. In addition, the X-axis is a direction that is orthogonal to the Y-axis and the Z-axis.

The aroma inhaler 100 of this embodiment is configured to generate aroma-containing mist by, for example, heating a stick-shaped aroma-producing product having an aroma source containing a mist source.

As shown in FIGS. 1A to 1C , the aroma inhaler 100 includes a housing 101, a sliding cover 102, a switch portion 103, and a terminal 104. The housing 101 is a housing constituting the outermost surface of the aroma inhaler 100, and has a size that can be accommodated by a user's hand. When using the aroma inhaler 100, the user can hold the aroma inhaler 100 with his hand to inhale the mist. The housing 101 can be constructed by assembling a plurality of components. In addition, the housing 101 can be formed of a metal such as aluminum. The housing 101 may also be made of resin, such as polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (Polyether Ether Ketone), or a component formed of a polymer alloy containing multiple polymers.

The outer shell 101 has an opening (not shown in the figure) for receiving the aroma product, and the sliding cover 102 is slidably mounted on the outer shell 101 in a manner of closing the opening. Specifically, the sliding cover 102 is configured to be movable along the outer surface of the outer shell 101 between a closed position (the position shown in FIG. 1A and FIG. 1B ) for closing the opening of the outer shell 101 and an open position for opening the opening. For example, the user can manually operate the sliding cover 102 to move the sliding cover 102 between the closed position and the open position. This allows or restricts the aroma product from entering the sliding cover 102 and the interior of the aroma inhaler 100.

The switch portion 103 is used to switch the on and off of the action of the aroma inhaler 100. For example, when the user inserts the aroma product into the aroma inhaler 100, the user operates the switch portion 103, so that the power is supplied from the power source not shown in the figure to the heating portion not shown in the figure, and the aroma product can be heated without burning the aroma product. In addition, the switch portion 103 can be a switch disposed outside the outer shell 101 or a switch located inside the outer shell 101. When the switch is located inside the outer shell 101, the switch is indirectly pressed down by pressing the switch portion 103 on the surface of the outer shell 101. In this embodiment, an example in which the switch of the switch portion 103 is located inside the outer shell 101 is described.

Terminal 104 is an interface such as USB that connects the aroma inhaler 100 to an external power source. When the power source of the aroma inhaler 100 is a rechargeable battery, by connecting the external power source to terminal 104, the external power source can flow current to the power source to charge the power source. In addition, the aroma inhaler 100 can be configured in a manner that data related to the operation of the aroma inhaler 100 can be transmitted to an external device by connecting a data transmission cable to terminal 104.

Next, the aroma product used in the aroma inhaler 100 of this embodiment is described. FIG. 2 is a schematic side sectional view of the aroma product 110. In this embodiment, a smoking system can be formed by the aroma inhaler 100 and the aroma product 110. In the example shown in FIG. 2, the aroma product 110 can have: a filling portion 111 filled with a smokeable substance, and a filter segment including a filter portion 115 and a hollow filter portion 116. The hollow filter portion 116 can be located closer to the smokeable substance side than the filter portion 115. Specifically, the flavor product 110 may be a rod-shaped non-combustible heating cigarette having a smokeable substance, an interface portion, and a second roll of paper 113 such as a tip papper that wraps the smokeable substance. The interface portion has a cylindrical member 114 and a filter segment. The filter segment has a hollow filter portion 116 and a filter portion 115. With respect to the axial direction of the flavor product 110 (also referred to as the "long axis direction"), the cylindrical member 114 serving as a cooling segment may be adjacent to the smokeable substance and the filter segment and be clamped. In addition, in the cylindrical member 114, openings V may be provided concentrically in the circumferential direction of the cylindrical member 114. The opening V provided in the cylindrical member 114 in the aroma product 110 is usually a hole used to promote the inflow of air from the outside through the user's inhalation. The inflow of air can reduce the temperature of the components or air flowing in from the smokable substance.

The stick-shaped aroma product 110 is preferably a columnar shape having a height-to-width ratio of 1 or more as defined below.

Aspect ratio = h/w

w is the width of the bottom surface of the column (in this manual, it is set as the width of the bottom surface on the smokeable side), h is the height, and it is better that h≧w. In this manual, the long axis direction is defined as the direction indicated by h. Therefore, even when w≧h, the direction indicated by h is simply referred to as the long axis direction. The shape of the bottom surface is not limited, and can be polygonal, arc-angled polygonal, circular, or elliptical, etc. The width w is the diameter when the bottom surface is circular, the major diameter when it is elliptical, and the diameter of the circumscribed circle or the major diameter of the circumscribed ellipse when it is polygonal or arc-angled polygonal.

The flavor product 110 may have a first roll of paper 112 for wrapping the smokeable substance. The length of the long side direction of the flavor product 110 is preferably 40 mm to 90 mm, particularly preferably 50 mm to 75 mm, and more preferably 50 mm to 60 mm. In more detail, the length h in the long axis direction of the flavor product 110 is not particularly limited, for example, it is usually 40 mm or more, preferably 45 mm or more, and particularly preferably 50 mm or more. In addition, the length h in the long axis direction of the flavor product 110 is usually 100 mm or less, preferably 90 mm or less, and particularly preferably 80 mm or less. The circumference of the flavor product 110 is preferably 15 mm to 25 mm, particularly preferably 17 mm to 24 mm, and more preferably 20 mm to 23 mm. In more detail, the width w of the bottom surface of the columnar body of the aroma product 110 is not particularly limited, for example, it is usually 5 mm or more, preferably 5.5 mm or more. In addition, the width w of the bottom surface of the columnar body of the aroma product 110 is usually 10 mm or less, preferably 9 mm or less, and particularly preferably 8 mm or less. In addition, the length of the smokeable material in the aroma product 110 can be 18 mm to 22 mm, the length of the first roll of paper 112 can be 18 mm to 22 mm, the length of the hollow filter part 116 can be 7 mm to 9 mm, and the length of the filter part 115 can be 6 mm to 8 mm.

In the length of the long axis direction of the fragrance product 110, the ratio of the length of the tubular member 114 and the filter segment (tubular member 114: filter segment) is not particularly limited. From the perspective of the amount of fragrance delivered or the appropriate mist temperature, it is generally 0.60 to 1.40:0.60 to 1.40, preferably 0.80 to 1.20:0.80 to 1.20, particularly preferably 0.85 to 1.15:0.85 to 1.15, more preferably 0.90 to 1.10:0.90 to 1.10, and particularly preferably 0.95 to 1.05:0.95 to 1.05. By setting the ratio of the length of the cylindrical member 114 and the filter segment within the above range, a cooling effect can be obtained, the effect of suppressing the loss caused by the generated steam and mist adhering to the inner wall of the cylindrical member 114, and the balance of the air volume and the fragrance adjustment function of the filter can be achieved, thereby achieving a good fragrance and fragrance intensity. In particular, when the cylindrical member 114 is lengthened, the particle formation of mist can be promoted to achieve a good fragrance, but when it is too long, the passing substances will adhere to the inner wall.

The structure of the interface is not particularly limited as long as the cylindrical member 114 is sandwiched by the smokeable substance and the filter segment relative to the axial direction of the flavor producing product 110. In other words, the flavor producing product 110 may have the cylindrical member 114 between the smokeable substance and the filter segment. The following is a detailed description of the filter segment and the cylindrical member 114.

(Revelation about filter segment)

The filter segment includes the filter portion 115, and there is no particular limitation as long as it has the function of a general filter. The general functions of the filter include, for example, adjusting the amount of air mixed in when inhaling mist, or reducing the aroma, nicotine or tar, etc., but it is not required to have all these functions. In addition, compared with paper roll cigarette products, in electric heating cigarette products that have less generated components and tend to have a lower filling rate of tobacco fillers, suppressing the filtering function and preventing the tobacco filler from falling is also one of the important functions.

(About the size disclosure)

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 according to the size of the product, and is usually 4.0 mm to 9.0 mm, preferably 4.5 mm to 8.5 mm, and particularly preferably 5.0 mm to 8.0 mm. In addition, when the cross-section is not circular, the above diameter is the diameter of a virtual circle having the same area as the cross-sectional area. The circumference of the cross-sectional shape of the filter segment in the circumferential direction can be appropriately changed according to the size of the product, and is usually 14.0 mm to 27.0 mm, preferably 15.0 mm to 26.0 mm, and particularly preferably 16.0 mm to 25.0 mm. The axial length of the filter segment can be appropriately changed according to the size of the product, usually between 15 mm and 35 mm, preferably between 17.5 mm and 32.5 mm, and particularly preferably between 20.0 mm and 30.0 mm. The shape or size of the filter section 115 can be appropriately adjusted by making the shape or size of the filter segment within the above range.

(Disclosure about filter unit 115)

The filter section 115 constituting the filter segment may be manufactured, for example, by the manufacturing method described below, or may be a commercially available product. In addition, the form of the filter segment is not particularly limited, and may be a common filter including a single filter segment, or a multi-segment filter including a plurality of filter segments such as a double filter or a triple filter. The filter segment may be manufactured by a generally known method, for example, when using synthetic fibers such as cellulose acetate tow as the material of the filter section 115, it may be manufactured by a method of spinning a polymer solution including a polymer and a solvent and rolling it. This method may be, for example, the method described in Japanese International Publication No. 2013/067511. In the manufacture of the filter segment, the adjustment of the air permeability resistance or the addition of additives (commonly known adsorbents or fragrances (such as menthol), granular activated carbon, fragrance retaining materials, etc.) to the filter section 115 can be appropriately designed. The shape of the filter section 115 constituting the filter segment is not particularly limited, and generally known shapes can be adopted, such as processing cellulose acetate tow into a cylindrical shape. The single filament fiber density and total fiber density of the cellulose acetate tow are not particularly limited. In the case of an interface component with a circumference of 22 mm, the single filament fiber density is preferably 5 g/9000 m or more and 12 g/9000 m or less, and the total fiber density is preferably 12000 g/9000 m or more and 35000 g/9000 m or less. The cross-sectional shape of the fiber of the cellulose acetate tow can be circular, elliptical, Y-shaped, I-shaped, R-shaped, etc. When the filter portion 115 is filled with the cellulose acetate tow, in order to increase the hardness of the filter, triacetin (plasticizer) can be added in an amount of 5% by weight to 10% by weight relative to the weight of the cellulose acetate tow. In addition, a paper filter filled with sheet-shaped pulp paper can be used to replace the acetate tow.

(Disclosure about the hollow filter section 116)

The filter segment may include a hollow filter portion 116 having one or more hollow portions. The hollow filter portion 116 is usually arranged on the side of the cylindrical member 114 relative to the filter portion 115, and is preferably arranged adjacent to the cylindrical member 114.

1.0mm以上

5.0mm以下。填充層由於纖維的填充密度高，所以於吸嚐時空氣或霧氣僅於中空部流通，於填充層內幾乎不流通。由於中空濾器部116內部的填充層為纖維填充層，所以於使用時從外側的觸感，對於使用者而言不太會帶來不適感。另外，中空濾器部116亦可不具有內栓塞包材，而是藉由熱成型來保持該形狀。中空濾器部116的硬度較佳係大於濾器部115的硬度。具體而 言，中空濾器部116所含有之塑化劑的質量百分比較佳係大於濾器部115所含有之塑化劑的質量百分比。於香味產生物品110中，在欲縮減濾器部115中的霧氣成分因過濾所造成之減少時，縮短濾器部115的長度並以中空濾器部116來取代者，對於增大霧氣的傳送量而言為有效。 The hollow filter portion 116 is composed of a filling layer having one or more hollow portions, and an inner plugging packaging material (inner winding paper) covering the filling layer. The hollow portion can be set at any position of the hollow filter portion 116. The hollow filter portion 116 has the function of increasing the strength of the interface portion. The filling layer can be formed as, for example, a rod filled with cellulose acetate fibers at a high density, and a plasticizer containing triacetin is added in an amount of not less than 6 mass % and not more than 20 mass % relative to the mass of cellulose acetate, and then hardened. The inner diameter of the hollow filter portion 116 can be

1.0mm or more

5.0mm or less. Since the filling density of the fiber in the filling layer is high, the air or mist only flows in the hollow part during inhalation, and hardly flows in the filling layer. Since the filling layer inside the hollow filter portion 116 is a fiber filling layer, the touch from the outside during use will not cause much discomfort to the user. In addition, the hollow filter portion 116 may not have an inner plug packaging material, but the shape may be maintained by thermoforming. The hardness of the hollow filter portion 116 is preferably greater than the hardness of the filter portion 115. Specifically, the mass percentage of the plasticizer contained in the hollow filter portion 116 is preferably greater than the mass percentage of the plasticizer contained in the filter portion 115. In the aroma product 110, when it is desired to reduce the reduction of the mist component in the filter portion 115 due to filtration, shortening the length of the filter portion 115 and replacing it with a hollow filter portion 116 is effective in increasing the amount of mist transmitted.

(Disclosure about filter density)

The density of the filter portion 115 is not particularly limited, and is generally 0.10 g/cm ³ to 0.25 g/cm ³ , preferably 0.11 g/cm ³ to 0.24 g/cm ³ , and particularly preferably 0.12 g/cm ³ to 0.23 g/cm ³ .

(Disclosure about filter packaging materials (inner and outer roll-up paper))

From the viewpoint of improving strength and structural rigidity, the filter segment may have a roll paper (filter plug roll paper) that is wound around the filter portion 115 and the like. The shape of the roll paper is not particularly limited, and may include one or more rows of joints containing adhesives. The adhesive may contain a hot melt adhesive, and further, the hot melt adhesive may contain polyvinyl alcohol. In addition, when the filter segment is composed of two or more segments, the roll paper preferably rolls up these two or more segments together. The material of the roll paper is not particularly limited, and generally known ones may be used. In addition, it may contain fillers such as calcium carbonate, etc. There is no particular restriction on the thickness of the roll paper, which is usually 20 μm to 140 μm, preferably 30 μm to 130 μm, and particularly 30 μm to 120 μm. There is no particular restriction on the unit area weight (or basis weight) of the roll paper, which is usually 20 gsm to 100 gsm, preferably 22 gsm to 95 gsm, and particularly 23 gsm to 90 gsm. In addition, the roll paper may be coated or uncoated, but from the perspective of imparting functions other than strength or structural rigidity, it is preferably coated with the desired material.

The hollow filter section 116 and the filter section 115 can be connected by, for example, an external plugging packaging material (external roll paper). The external plugging packaging material can be, for example, a cylindrical paper. In addition, the smokeable material and the cylindrical component 114 can be connected to the connected hollow filter section 116 and the filter section 115, for example, by an interface lining (the second roll paper 113). Such a connection can be, for example, by applying a vinyl acetate-based glue on the inner side of the interface lining, and loading the smokeable material, the cylindrical component 114, and the connected hollow filter section 116 and the filter section 115, and then rolling them up to connect. In addition, these can be connected by dividing multiple sheets of lining paper into multiple times.

(Disclosure on the addition of activated carbon)

Activated carbon may be added to at least a portion of the filter portion 115. The amount of activated carbon added to one fragrance product 110 is calculated as the value of the specific surface area of activated carbon × the weight of activated carbon / the cross-sectional area in the direction perpendicular to the air permeation direction of the filter portion 115, and is 15.0 m ² /cm ² or more and 80.0 m ² /cm ² or less. The above "specific surface area of activated carbon × the weight of activated carbon / the cross-sectional area in the direction perpendicular to the air permeation direction of the filter portion 115" is sometimes simply expressed as "the 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 possessed by one fragrance producing product 110, the weight of the activated carbon added, and the cross-sectional area of the filter portion 115. In addition, the activated carbon is sometimes not evenly dispersed in the filter portion 115 to which the activated carbon is added, so it is not required that all cross-sections of the filter portion 115 (cross-sections in a direction perpendicular to the air permeability direction) satisfy the above range. By making the surface area of the activated carbon per unit cross-sectional area within the above range, the components generated by heating can be delivered to the user in a desired amount, and the desired fragrance can be given to the user. When the surface area of the activated carbon per unit cross-sectional area is less than the lower limit of the above range, the effect brought about by the addition of the activated carbon cannot be fully obtained. On the other hand, when the surface area of the activated carbon per unit cross-sectional area is greater than the upper limit of the above range, the components generated by heating will be reduced more than necessary.

The surface area of the activated carbon per unit cross-sectional area is preferably 17.0 m ² /cm ² or more, more preferably 35.0 m ² /cm ² or more. On the other hand, it is preferably 77.0 m ² /cm ² or less, more preferably 73.0 m ² /cm ² or less. The surface area of the activated carbon per unit cross-sectional area can be adjusted, for example, by adjusting the specific surface area of the activated carbon and its added amount, and the cross-sectional area in a direction perpendicular to the air permeation direction of the filter section 115. The above-mentioned surface area of the activated carbon per unit cross-sectional area is calculated based on the filter section 115 to which the activated carbon is added. When the filter segment is composed of a plurality of filter sections 115, the cross-sectional area and length of the filter section 115 to which the activated carbon is added are used as the basis.

The activated carbon that can be used in this embodiment includes, for example, those made of wood, bamboo, coconut shell, walnut shell, coal, etc. In addition, the activated carbon that can be used in this embodiment has a BET specific surface area of 1100 m ² /g to 1600 m ² /g, preferably 1200 m ² /g to 1500 m ² /g, and more preferably 1250 m ² /g to 1380 m ² /g. The BET specific surface area can be obtained by a nitrogen adsorption method (BET multi-point method). In addition, the activated carbon that can be used in this embodiment has a pore volume of 400 μL/g to 800 μL/g, more preferably 500 μL/g to 750 μL/g, and more preferably 600 μL/g to 700 μL/g. The pore volume can be calculated from the maximum adsorption amount obtained using the nitrogen adsorption method.

In this embodiment, the amount of activated carbon added per unit length in the air permeation direction of the filter portion 115 to which activated carbon is added is preferably 5 mg/cm to 50 mg/cm, more preferably 8 mg/cm to 40 mg/cm, and even more preferably 10 mg/cm to 35 mg/cm. In this embodiment, by making the specific surface area of the activated carbon and the amount of activated carbon added within the above range, the surface area of the activated carbon per unit cross-sectional area can be adjusted to a desired value. In addition, the activated carbon that can be used in this embodiment is preferably one in which the cumulative 10 volume % particle size (particle size D10) of the activated carbon particles is 250 μm to 1200 μm. In addition, the cumulative 50 volume % particle size (particle size D50) of the activated carbon particles is preferably 350 μm to 1500 μm. In addition, D10 and D50 are measured by laser diffraction scattering method. An example of a device suitable for this measurement is the laser diffraction scattering particle size distribution measuring device "LA-950" produced by Horiba, Ltd. Powder and pure water are flowed into the unit of this device, and the particle size is detected based on the light scattering information of the particles. The measurement conditions of this device are as follows.

Measurement mode: Manual flow mode unit measurement

Dispersion medium: ion exchange water

Dispersion method: Measure after 1 minute of ultrasonic irradiation

Refractive index: 1.92-0.00i (sample refraction)/1.33-0.00i (dispersive medium refractive index)

Number of measurements: Change the sample and measure twice

In this aspect, there is no particular limitation on the method of adding activated carbon to the filter section 115, as long as the activated carbon is added in a substantially uniformly dispersed manner in the filter section 115 to which it is added. In addition, the filter segment can be, for example, one manufactured by a generally known manufacturing method, or a commercially available product can be used. In addition, there is no particular limitation on the aspect of the filter segment, and it can be configured as a filter including a single filter segment, or a multi-segment filter including a plurality of filter segments such as a double filter or a triple filter. In the case of a filter section 115 composed of a single filter segment, the filter section 115 to which the activated carbon is added directly becomes a filter segment. On the other hand, when the filter is composed of a plurality of filter segments, the filter section 115 to which activated carbon is added is preferably arranged on the upstream side of the filter section 115 constituting the inlet end. On the other hand, activated carbon may also be added to the filter section 115 constituting the inlet end. In addition, when the filter segment is a multi-segment filter, the length of the filter segment that serves as the standard for the amount of activated carbon added is the length of the filter section 115 to which activated carbon is added. The amount of activated carbon added is measured relative to the weight of the filter segment as a whole, and can be, for example, 4.0 mg to 24.0 mg, preferably 4.5 mg to 23.0 mg, and more preferably 10.5 mg to 22.0 mg.

(Disclosure of the cylindrical component 114)

The cylindrical member 114 can be clamped adjacent to the smokeable substance and the filter segment. The cylindrical member 114 generally includes: a rod-shaped or cylindrical member having a hollow (hollow) hole in the circumferential cross section of a cylinder or the like.

(Disclosure of the dimensions of the tubular member 114)

The length of the long axis direction of the tubular member 114 can be appropriately changed according to the size of the product, and is usually 15 mm or more, preferably 20 mm or more, and particularly preferably 25 mm or more. In addition, it is usually 40 mm or less, preferably 35 mm or less, and particularly preferably 30 mm or less. By setting the length of the long axis direction of the tubular member 114 to be above the above lower limit, a sufficient cooling effect can be ensured and a good fragrance can be obtained. By setting it to be below the above upper limit, the loss caused by the generated steam and mist adhering to the inner wall of the tubular member 114 can be suppressed.

The tubular member 114 may also be filled with a sheet or the like for cooling. The total surface area of the tubular member 114 is not particularly limited, and may be, for example, 300 mm ² /mm or more and 1000 mm ² /mm or less. This surface area is the surface area per unit length (mm) in the air permeation direction of the tubular member 114. The total surface area of the tubular member 114 is preferably 400 mm ² /mm or more, and more preferably 450 mm ² /mm or more. On the other hand, it is preferably 600 mm ² /mm or less, and more preferably 550 mm ² /mm or less. The tubular member 114 is expected to have a large total surface area in its internal structure. Therefore, in a preferred embodiment, the tubular member 114 may include a sheet of material formed by forming wrinkles to form a channel, then forming creases, wrinkles, and folding. When there are more folds or creases in the volume of the element, the total surface area of the tubular member 114 increases. The thickness of the constituent material of the tubular member 114 is not particularly limited, and may be, for example, from 5 μm to 500 μm, or from 10 μm to 250 μm.

(Revelation about smokeable substances)

The shape of the smokeable material is not particularly limited as long as it is a generally known shape, and is usually a shape in which a tobacco filler is wrapped by a rolling paper (the first rolling paper 112). The tobacco filler is not particularly limited, and the first tobacco filler or the second tobacco filler described below can be used. In addition, in the description of this application, the molded products of dry tobacco such as tobacco shreds, tobacco sheets, and tobacco granules described below are sometimes referred to as "dried tobacco leaves". In addition, the smokeable material may also have a fitting portion with a heater component for heating a cigarette product.

(About the size of smokeable items)

The smokable object formed by wrapping the tobacco filling material with rolling paper preferably has a columnar shape. In this case, the height-to-width ratio represented by the height of the long axis direction of the smokable object relative to the width of the bottom surface of the smokable object is preferably greater than 1. The shape of the bottom surface is not limited, and can be polygonal, arc-shaped polygonal, circular, elliptical, etc. The width is the diameter when the bottom surface is circular, the major diameter when it is elliptical, and the diameter of the circumscribed circle or the major diameter of the circumscribed ellipse when it is polygonal or arc-shaped polygonal. The height of the tobacco filling material constituting the smokable object is preferably about 10mm to 70mm, and the width is about 4mm to 9mm.

The length of the smokable material in the long axis direction can be appropriately changed according to the size of the product, and is usually 10 mm or more, preferably 12 mm or more, particularly 15 mm or more, and more preferably 18 mm or more. In addition, it is usually 70 mm or less, preferably 50 mm or less, particularly 30 mm or less, and more preferably 25 mm or less. In addition, there is no special restriction on the ratio of the length of the smokable material to the overall length h of the long axis direction of the flavor product 110. From the perspective of the balance between the transmission amount and the mist temperature, it is usually 10% or more, preferably 20% or more, particularly 25% or more, and more preferably 30% or more. In addition, it is usually 80% or less, preferably 70% or less, particularly 60% or less, more preferably 50% or less, particularly preferably 45% or less, and most preferably 40% or less.

(Revelation about filling amount)

There is no special restriction on the content of dry tobacco leaves in the smokable substance, which can be listed as 200mg/1 smokable substance and less than 800mg/1 smokable substance, preferably 250mg/1 smokable substance and less than 600mg/1 smokable substance. This range is particularly suitable for smokable substances with a circumference of 22mm and a length of 20mm.

(Revelation about fillers (No. 1 tobacco filler: shredded filler))

First, the first tobacco filler (also referred to as the "first filler") is explained. The material of the tobacco shreds (flavor source) contained in the first filler is not particularly limited, and tobacco leaves or leaf veins or other generally known plants can be used. In addition, the shape of the tobacco and other flavor sources can be shreds, sheets, ribbons, powders, granules, particles, slurries or porous forms. Specifically, for example, the dried tobacco leaves can be crushed into an average particle size of more than 20μm and less than 200μm to form a tobacco crushed material, and the homogenized material is processed into sheets (hereinafter referred to as homogenized sheets), and then the shredded material is cut. Furthermore, a uniform sheet having the same length as the long side direction of the smokeable material may be cut into shreds roughly horizontally to the long side direction of the smokeable material and filled into the smokeable material, that is, a so-called bundled type. Furthermore, the above-mentioned warp sheet may not be cut into shreds, but the wrinkled sheet may be used as the smokeable material. In addition, the width of the tobacco shreds for filling the smokeable material is preferably 0.5 mm or more and 2.0 mm or less. When the size of the smokeable material is 20 mm to 23 mm in circumference and 18 mm to 22 mm in length, the content of the smokeable material such as tobacco in the flavor product 110 is, for example, 200 mg to 400 mg, preferably 250 mg to 320 mg.

Regarding the tobacco leaves used in the production of the above-mentioned tobacco shreds and uniform sheets, various types of tobacco can be used. For example, yellow varieties, Burley varieties, Oriental varieties, future varieties, other tobacco leaf Acacia (Nicotiana Tabacum) series varieties, Yellow Flower Tobacco (Nicotiana Rustica) series varieties, and mixtures thereof. Regarding the mixture, the above-mentioned varieties can be appropriately blended and used in a manner to achieve the desired flavor. The details of the above-mentioned tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Comprehensive Research Center, 2009.3.31". There are multiple previous methods for the production method of the above-mentioned uniform sheets, that is, the method of crushing tobacco leaves and processing them into uniform sheets. The first method is to use a papermaking process to make paper sheets. The second method is to mix a suitable solvent such as water into crushed tobacco leaves and homogenize them, then cast the homogenized product thinly on a metal plate or metal plate belt and dry it to make a cast sheet. The third method is to mix a suitable solvent such as water into crushed tobacco leaves and homogenize them, then extrude them into sheets to make rolled sheets. The types of the above-mentioned homogenized sheets are detailed in "Tobacco Dictionary, Tobacco General Research Center, 2009.3.31".

The moisture content of the tobacco filler can be 8% to 18% by weight relative to the total amount of the tobacco filler, preferably 10% to 16% by weight, particularly preferably 10% to 15% by weight, and even more preferably 11% to 13% by weight. At this moisture content, the occurrence of rolling seepage can be suppressed, so that the rolling suitability during the manufacture of the smokable product can be improved. In addition, the flavor product 110 is easy to deform appropriately in accordance with the cross-sectional shape of the retaining portion. There is no particular restriction on the size of the tobacco shreds contained in the first tobacco filler and the method of preparing the shreds. For example, dried tobacco leaves cut into shreds with a width of 0.5 mm to 2.0 mm can be used, and shreds with a width of 0.8 mm to 1.2 mm are preferred. In addition, when using the crushed material of uniform flakes, it is also possible to use: crush the dried tobacco leaves into an average particle size of about 20μm to 200μm and process the uniform flakes, and cut the flakes into a width of 0.5mm to 2.0mm, preferably 0.8mm to 1.2mm.

The first tobacco filler may contain an aerosol base material for generating aerosol smoke. The type of the aerosol base material is not particularly limited, and extracts from various natural products and/or their constituent components can be selected according to the application. The aerosol base material can be listed as: glycerol, propylene glycol, triacetin, 1,3-butylene glycol and mixtures 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. From the perspective of fully generating aerosol and giving a good flavor, it is usually 5% by weight or more, preferably 10% by weight or more, relative to the total amount of the tobacco filler. In addition, it is usually 50% by weight or less, preferably 15% by weight or more and 25% by weight or less.

The first tobacco filler may contain a flavor. The type of the flavor is not particularly limited, and from the perspective of imparting a good aroma, it may be the same flavor as the above-mentioned flavor added to the filter portion 115.

The content of the flavor in the first tobacco filler is not particularly limited. From the perspective of imparting a good flavor, it is usually 10,000 ppm or more, preferably 20,000 ppm or more, and particularly preferably 25,000 ppm or more. In addition, it is usually 70,000 ppm or less, preferably 50,000 ppm or less, particularly preferably 40,000 ppm or less, and even more preferably 33,000 ppm or less.

The filling density of the first tobacco filler is not particularly limited, but is generally 250 mg/cm ³ or more, preferably 300 mg/cm 3 or more, and generally 400 mg/cm ³ or less, preferably 350 mg/cm ³ or less, from the viewpoint of ensuring the performance of the flavor product ¹¹⁰ and imparting a good flavor. The first tobacco filler is wrapped with a wrapping paper so as to be inside to form a smokable product.

(Disclosure about fillers (No. 2 tobacco filler: sheet filler))

The second tobacco filler is composed of tobacco sheets filled in the filled object. The number of tobacco sheets can be 1 sheet or 2 sheets or more. When the second tobacco filler is composed of 1 tobacco sheet, for example, a tobacco sheet having one side with the same length as the long side direction of the filled object is filled in a state of being folded back multiple times horizontally with the long side direction of the filled object (so-called wrinkled sheet). In addition, it can also be cited that a tobacco sheet having one side with the same length as the long side direction of the filled object is filled in a state of being rolled in a direction orthogonal to the long side direction of the filled object.

The second tobacco filling material is composed of more than two tobacco sheets. For example, a plurality of tobacco sheets having one side having the same length as the long side direction of the filled material are arranged in a concentric manner and are wound in a direction orthogonal to the long side direction of the filled material. The so-called "arranged in a concentric manner" means that the centers of all tobacco sheets are arranged in approximately the same position. In addition, there is no particular restriction on the number of tobacco sheets, and the embodiments of 2, 3, 4, 5, 6 or 7 sheets can be listed. More than two tobacco sheets may all have the same composition or physical properties, and a part or all of each tobacco sheet may have different compositions or physical properties. In addition, the thickness of each tobacco sheet may be the same or different.

The second tobacco filler can be prepared by preparing a plurality of tobacco sheets of different widths, and preparing a stacked body in a manner where the width decreases from the bottom to the top, so that this is passed through a winding tube and rolled and formed. According to this manufacturing method, the plurality of tobacco sheets extend in the long-side direction and are arranged concentrically with the long-side axis as the center. In addition, between the long-side axis and the innermost tobacco sheet, an interlocking portion extending in the long-side direction can be formed.

In this manufacturing method, the laminate is preferably prepared in a manner that non-contact portions are formed between the adjacent tobacco sheets after rolling. When non-contact portions (gaps) that are not in contact with the tobacco sheets exist between the plurality of tobacco sheets, the aroma flow path can be ensured and the transfer efficiency of the aroma components can be improved. On the other hand, since the heat from the heater can be transferred to the outer tobacco sheets through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured. In order to provide non-contacting portions between multiple tobacco sheets, for example, the following methods can be used: using embossed tobacco sheets, laminating without contacting adjacent tobacco sheets on the entire surface, laminating with contacting adjacent tobacco sheets on a portion of the surface, or laminating with contacting adjacent tobacco sheets on the entire surface or a portion of the surface in a manner of peeling off after rolling and forming, and thereby preparing a laminated body. When preparing a smokable product including a roll of paper, the roll of paper can be arranged at the bottom of the laminated body. In addition, a cylindrical substitute sheet (dummy) such as a mandrel may be placed on the top of the laminate to form the second tobacco filler, and then the substitute sheet may be removed to form the interlocking portion.

The filling density of the second tobacco filler is not particularly limited. From the perspective of ensuring the performance of the cigarette product and imparting a good flavor, it is usually 250 mg/ ^cm3 or more, preferably 300 mg/ ^cm3 or more. In addition, it is usually 400 mg/ ^cm3 or less, preferably 350 mg/ ^cm3 or less.

The tobacco sheet may contain an aerosol base material that generates aerosol smoke when heated. Aerosol sources such as glycerin, propylene glycol, 1,3-butylene glycol and other polyols may be added as the aerosol base material. The amount of the aerosol base material added is preferably 5% by weight to 50% by weight, and more preferably 15% by weight to 25% by weight, relative to the dry weight of the tobacco sheet.

Tobacco sheets can be appropriately manufactured by generally known methods such as papermaking, slurry, and rolling. In addition, the uniform sheets described in the first tobacco filler can also be used. In the case of papermaking, it can be manufactured by a method including the following steps. 1) Roughly pulverize dried tobacco leaves, extract with water and separate into water extract and residue. 2) Reduce pressure and dry the water extract and concentrate it. 3) Add pulp to the residue and make paper after fiberization by a refiner. 4) Add the concentrated liquid of the water extract to the sheet after papermaking and dry it to form a tobacco sheet. In this case, it is also possible to add a step of removing some components such as nitrosamines (see Japanese Patent Publication No. 2004-510422). In the case of the slurry method, it can be manufactured by a method including the following steps. 1) Mixing water, pulp, binder, and crushed tobacco leaves. 2) Thinly stretching (casting) the mixture and drying it. In this case, it is also possible to add a step of removing some components such as nitrosamines by irradiating the slurry mixed with water, pulp, binder, and crushed tobacco leaves with ultraviolet rays or X-rays.

In addition, as described in Japanese International Publication No. 2014/104078, a non-woven tobacco sheet can also be used: a non-woven tobacco sheet produced by a method comprising the following steps. 1) Mixing powdered tobacco leaves and a binder. 2) Sandwiching the mixture with a non-woven fabric. 3) Forming the laminate into a certain shape by heat fusion to obtain a non-woven tobacco sheet. The type of tobacco leaves used as the raw material in the above methods can be the same as that described in the first filler. The composition of the tobacco sheet is not particularly limited. For example, the content of tobacco raw materials (tobacco leaves) is preferably not less than 50% by weight and not more than 95% by weight relative to the total weight of the tobacco sheet. In addition, the tobacco sheet may contain a binder, which may include, for example, guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), etc. The amount of the binder relative to the total weight of the tobacco sheet is preferably 1% by weight or more and 10% by weight or less. The tobacco sheet may further contain other additives. The additives may include fillers such as pulp. In this embodiment, a plurality of tobacco sheets are used, and the tobacco sheets may all be of the same composition or physical properties, or a part or all of the tobacco sheets may be of different compositions or physical properties.

The second tobacco filler can be prepared by preparing a plurality of tobacco sheets of different widths, and preparing a laminated body in which the width decreases from the bottom to the top, and then passing the laminated body through a winding tube and rolling it into shape. According to this manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically with the longitudinal axis as the center. In addition, an interlocking portion extending in the longitudinal direction can be formed between the longitudinal axis and the innermost tobacco sheet. In this manufacturing method, the laminated body is preferably prepared in a manner that a non-contact portion is formed between the adjacent tobacco sheets after rolling. When there is a non-contact portion (gap) between multiple tobacco sheets that the tobacco sheets do not touch, the aroma flow path can be ensured and the transfer efficiency of the aroma components can be improved. On the other hand, when using the cigarette product as an electrically heated cigarette product, since the heat from the heater can be transferred to the outer tobacco sheet through the contact portion of the multiple tobacco sheets, high heat transfer efficiency can be ensured.

In order to provide non-contacting portions between multiple tobacco sheets, for example, the following methods can be used to prepare a laminated body by using embossed tobacco sheets to laminate them without contacting the entire surface of adjacent tobacco sheets, or by laminated them with contacting a portion of adjacent tobacco sheets, or by laminating them with contacting the entire surface or a portion of adjacent tobacco sheets slightly after being rolled and formed. When preparing a smokeable product including a roll of paper, the roll of paper can be placed at the bottom of the laminated body. In addition, a cylindrical substitute sheet such as a mandrel may be placed on the top of the laminate to form the second tobacco filler, and then the substitute sheet may be removed to form the interlocking portion. The thickness of each tobacco sheet is not limited. From the perspective of both heat transfer efficiency and strength, it is preferably 150 μm to 1000 μm, and more preferably 200 μm to 600 μm. The thickness of each tobacco sheet may be the same or different. There is no particular limitation on the number of tobacco sheets constituting the second tobacco filler, and examples thereof include 2, 3, 4, 5, 6 or 7 sheets.

(Revelation about the roll of paper)

The flavor product 110 may include a second roll 113, which is a roll of at least one of the cylindrical member 114, the hollow filter portion 116, and the filter portion 115, and is different from the first roll 112. The second roll 113 may also be a roll of a portion of the first roll 112 that is used to wrap the smokeable material. The composition of the roll (hereinafter including the first roll 112 or the second roll 113) is not particularly limited and can be set to a general form, such as a roll with pulp as the main component. In addition to being made from wood pulps such as coniferous tree pulp or broadleaf tree pulp, paper pulp can also be made by mixing with non-wood pulps such as flax pulp, hemp pulp, ramie pulp, and reed pulp, which are generally used in cigarette paper rolls. The types of pulp that can be used include: chemical pulp formed by sulfate digestion, acidic, neutral, or alkaline sulfite digestion, sodium digestion, etc., groundwood pulp, chemical groundwood pulp, thermomechanical pulp, etc.

In the papermaking process using the above pulp and through a fourdrinier papermaking machine, a cylinder papermaking machine, a cylinder-short composite papermaking machine, etc., the texture is made uniform and the roll paper is made uniformly. In addition, a wet paper strength enhancer can be added as needed to impart water resistance to the roll paper, or a sizing agent can be added to adjust the printing degree of the roll paper. Furthermore, aluminum sulfate, various anionic, cationic, non-ionic or bi-polar yield enhancers, water filter enhancers, and paper strength enhancers and other internal additives for papermaking, as well as dyes, pH adjusters, defoamers, resin control agents (pitch controlling agents), and slime control agents (salm controlling agents) and other papermaking additives can be added.

The unit area weight of the roll base paper is usually, for example, 20 gsm or more, preferably 25 gsm or more. On the other hand, the unit area weight is usually 65 gsm or less, preferably 50 gsm or less, and more preferably 45 gsm or less. The thickness of the roll paper having the above characteristics is not particularly limited, and from the perspective of rigidity, air permeability, and ease of adjustment during papermaking, it is usually 10 μm or more, preferably 20 μm or more, and particularly preferably 30 μm or more. In addition, it is usually 100 μm or less, preferably 75 μm or less, and particularly preferably 50 μm or less. The shape of the roll paper of the fragrance product 110 can be square or rectangular. When using the rolling paper for wrapping tobacco filling (for making smokeable products), the length of one side can be listed as about 12mm to 70mm, the length of the other side can be listed as about 15mm to 28mm, the preferred length of the other side can be listed as 22mm to 24mm, and the more preferred length can be listed as about 23mm. When the tobacco filling is wrapped in the rolling paper into a columnar shape, for example, by overlapping the end of the rolling paper in the width direction with the end on the opposite side by about 2mm and sticking them, a columnar paper tube shape is formed, and the shape filled with tobacco filling is formed therein. The size of the rectangular rolling paper can be determined by the size of the smokeable product after completion. When the smokeable article is connected to other components adjacent to the smokeable article and rolled up like the tipping paper, the length of one side can be listed as 20mm to 60mm and the length of the other side can be listed as 15mm to 28mm.

In addition to the above-mentioned pulp, the roll paper may also contain fillers. The content of the filler relative to the total weight of the roll paper can be listed as 10% by weight or more and less than 60% by weight, preferably 15% by weight or more and 45% by weight or less. In the roll paper, in the preferred unit area weight range (25gsm or more and 45gsm or less), the filler is preferably 15% by weight or more and 45% by weight or less. Furthermore, when the unit area weight is 25gsm or more and 35gsm or less, the filler is preferably 15% by weight or more and 45% by weight or less, and when the unit area weight exceeds 35gsm and is 45gsm or less, the filler is preferably 25% by weight or more and 45% by weight or less. The filler may be calcium carbonate, titanium dioxide, kaolin, etc., and calcium carbonate is preferably used from the viewpoint of improving the fragrance or whiteness. The paper containing such fillers exhibits a bright white color, which is preferred from the viewpoint of the appearance of the roll paper used as the fragrance product 110, and can be kept white all the time. By containing a large amount of such fillers, the ISO whiteness of the roll paper can be set to 83% or more, for example. In addition, from the viewpoint of the practical use of the roll paper as the fragrance product 110, the first roll paper 112 and the second roll paper 113 preferably have a tensile strength of 8N/15mm or more. Thereby, even when the fragrance product 110 held in the holding portion is pulled out, the roll paper is not easily damaged. This tensile strength can be increased by reducing the content of the filler. Specifically, the tensile strength can be increased by reducing the filler content compared to the upper limit of the filler content indicated in the range of each unit area weight exemplified above.

Various auxiliary agents other than base paper or fillers can be added to the roll paper. For example, in order to improve water resistance, a water resistance enhancer can be added. Water resistance enhancers include wet paper strength enhancers (WS agents) and sizing agents. Examples of wet paper strength enhancers include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. In addition, examples of sizing agents include rosin soap, alkyl ketene dimer (AKD: Alkylketene Dimer), alkenyl succinic anhydride (ASA: Alkenyl Succinic Anhydride), highly saponified polyvinyl alcohol with a saponification degree of more than 90%, etc. A paper strength enhancer may also be added as an auxiliary agent, for example: polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, etc. In particular, it is known that only a very small amount of oxidized starch is needed to improve air permeability (Japanese Patent Publication No. 2017-218699). In addition, the roll paper may be appropriately coated.

A coating agent may be added to at least one of the two surfaces of the roll paper, the surface and the back. The coating agent is not particularly limited, and preferably is a coating agent that forms a film on the surface of the paper to reduce the permeability of liquids. Examples include: alginic acid and its salts (e.g., sodium salt); polysaccharides such as pectin; cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, and nitrocellulose; starch or its derivatives (e.g., ether derivatives such as carboxymethyl starch, hydroxyalkyl starch, and cationic starch, or ester derivatives such as acetic starch, phosphate starch, and octenyl succinic acid starch).

(Disclosure about the tipping paper (2nd roll 113))

The composition of the tipping paper is not particularly limited, and it can be composed of a general form, for example, a paper pulp as the main component. In addition to being made from wood pulp such as coniferous tree pulp or broadleaf tree pulp, the paper pulp can also be made by mixing with non-wood pulp generally used in rolling paper for tobacco products, such as linen pulp, hemp pulp, ramie pulp, and esparto. These pulps can be used as a single type or in combination of multiple types at any ratio. In addition, the tipping paper can be composed of one sheet or more than one sheet. The pulp that can be used includes chemical pulp, groundwood pulp, chemical groundwood pulp, thermomechanical pulp, etc. formed by sulfate digestion, acidic, neutral or alkaline sulfite digestion, sodium digestion, etc. In addition, the tipping paper can be manufactured by the manufacturing method described below or a commercial product can be used. The shape of the tipping paper is not particularly limited, for example, it can be formed into a square or rectangular shape.

There is no particular restriction on the weight per unit area of the tipping paper, which is usually between 32gsm and 40gsm, preferably between 33gsm and 39gsm, and particularly preferably between 34gsm and 38gsm. There is no particular restriction on the air permeability of the tipping paper, which is usually between 0 Coresta unit and 30,000 Coresta unit, preferably between more than 0 Coresta unit and 10,000 Coresta unit. The air permeability is a value measured in accordance with ISO 2965:2009, and is expressed as the flow rate (cm ³ ) of gas passing through an area of 1 cm ² per minute when the differential pressure between the two sides of the paper is 1 kPa. 1 Coresta unit (1 Corestaunit, 1 C.U.) is cm ³ /(min‧cm ² ) at 1 kPa.

In addition to the above-mentioned pulp, the tipping paper may also contain fillers, such as 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, etc. In particular, from the perspective of improving whiteness, opacity, and increasing heating speed, it is preferred to contain calcium carbonate. In addition, these fillers can be used alone or in combination of two or more.

In addition to the above-mentioned pulp or filler, various auxiliary agents can be added to the tipping paper, for example, in order to improve water resistance, a water resistance enhancer can be provided. Water resistance enhancers include wet paper strength enhancers (WS agents) and sizing agents. Examples of wet paper strength enhancers include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. In addition, examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), highly saponified polyvinyl alcohol with a saponification degree of more than 90%, etc.

In the tipping paper, a coating agent is added to at least one of the two surfaces, the front and the back. The coating agent is not particularly limited, but preferably a coating agent that can form a film on the surface of the paper to reduce the permeability of the liquid.

The structure of the flavor product 110 of this type can be used in electric heating cigarette products, but it can also be applied to cigarettes that are accompanied by combustion (paper roll cigarettes). A portion of the outer surface of the tipping paper can be covered by a lip-release material 117. The lip-release material 117 means a material that is constructed in a way that the contact between the auxiliary lip and the tipping paper is not substantially sticky and can be easily separated when the user holds the interface of the flavor product 110 in his mouth. The lip-release material 117 can contain, for example, ethyl cellulose, methyl cellulose, etc. For example, ethyl cellulose or methyl cellulose ink can be applied to the outer surface of the tipping paper, and the outer surface of the tipping paper can be coated with the lip-release material 117.

In this embodiment, the lip material 117 of the tipping paper is at least arranged in a predetermined suction port area that contacts the lips of the user when the user holds the interface. More specifically, the lip material arrangement area covered by the lip material 117 on the outer surface of the tipping paper is defined as the area between the suction port end of the interface and the air vent.

Next, the internal structure of the flavor inhaler 100 is explained. FIG. 3 is a cross-sectional view of the flavor inhaler when viewed from the arrow direction 3-3 shown in FIG. 1B . As shown in FIG. 3 , a placement portion 10 on which a contained object such as a power supply portion 20 or an atomization portion 30 described later is placed is provided on the inner side of the outer shell 101 of the flavor inhaler 100. The placement portion 10 is made of, for example, resin, and in particular, may be formed of a polymer alloy containing polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone) or a plurality of polymers. In addition, the placement portion 10 may include a portion formed of, for example, a metal such as aluminum. Here, from the viewpoint of heat resistance, processability, and strength, the placement portion 10 is preferably polycarbonate. The power supply unit 20 and the atomization unit 30 are disposed in the inner space of the mounting unit 10. In addition, the power supply unit 20 and the atomization unit 30 cannot be replaced after the flavor inhaler 100 is assembled. In addition, the outer shell 101 and the mounting unit 10 are sometimes collectively referred to as a frame.

The power supply unit 20 has a power supply 21. The power supply 21 may be, for example, a rechargeable battery or a non-rechargeable battery. The power supply 21 is electrically connected to the atomization unit 30. Thus, the power supply 21 can supply power to the atomization unit 30 in a manner that appropriately heats the aroma product 110.

As shown in the figure, the atomizing section 30 has: a chamber 50 (equivalent to an example of a storage section) extending in the insertion direction (Z-axis direction) of the aroma product 110, a heating section 40 arranged along the axial direction (Z-axis direction) of the chamber 50 and covering a portion of the chamber 50, a heat insulating section 32, and a roughly cylindrical insertion guide member 34. The chamber 50 is configured to accommodate the aroma product 110. On the inner circumferential surface of the chamber 50, a convex seat (gripping section, equivalent to an example of a protrusion) not shown in the figure is provided for holding the accommodated aroma product 110. The details of the convex seat will be described later.

The heating part 40 is configured to contact the outer peripheral surface of the chamber 50 to heat the aroma product 110 contained in the chamber 50. Here, the heating part 40 does not have a heating element for inserting the aroma product 110. As shown in the figure, a bottom member 36 can be provided at the bottom of the chamber 50. The bottom member 36 can play the function of a stopper for positioning the aroma product 110 inserted into the chamber 50. The bottom member 36 has a concave-convex surface on the surface abutted by the aroma product 110, and can separate a space that can supply air to the surface abutted by the aroma product 110. In addition, the bottom member 36 is made of resin, for example, and can be formed of a polymer alloy containing polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone) or multiple polymers, or metals such as aluminum. In order to suppress heat from being transferred to the heat insulation part 32, etc., the bottom member 36 is preferably formed of a material with low thermal conductivity.

The heat insulating portion 32 is generally cylindrical in shape and is configured to cover the chamber 50. The heat insulating portion 32 may contain, for example, an aerogel sheet. The insertion guide member 34 is disposed between the outer shell 101 and the chamber 50. The insertion guide member 34 is configured in such a way that when the insertion guide member 34 is inserted into the frame from the opening of the outer shell 101, the hook will engage with the frame and will not detach from the frame. In addition, the insertion guide member 34 is, for example, made of resin, and in particular, may be formed of a polymer alloy containing polycarbonate (PC), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone) or a plurality of polymers. The insertion guide member 34 may be formed of metal, glass, ceramic, etc. In addition, from the viewpoint of heat resistance, the insertion guide member 34 is preferably PEEK. When the slide cover 102 is in the open position, the insertion guide member 34 is connected to the outside of the flavor inhaler 100, and the flavor product 110 is inserted into the through hole 34a of the insertion guide member 34 to guide the insertion of the flavor product 110 into the chamber 50. When the slide cover 102 is in the open position, the through hole 34a of the insertion guide member 34 is exposed to the outside, and at least a part of the insertion guide member 34 is covered in the axial direction (Z-axis direction) of the chamber 50. In FIG. 3, a two-point dashed line is used to indicate the state in which the slide cover 102 is closed in a manner of covering the entire through hole 34a of the insertion guide member 34.

Furthermore, the aroma inhaler 100 has a first holding portion 37 and a second holding portion 38 for holding both ends of the chamber 50 and the heat insulating portion 32. The first holding portion 37 is configured to hold the ends of the chamber 50 and the heat insulating portion 32 on the negative Z-axis direction side. The second holding portion 38 is configured to hold the ends of the chamber 50 and the heat insulating portion 32 on the sliding cover 102 side (on the positive Z-axis direction side).

Next, the structure of the chamber 50 is described. FIG. 4A is a three-dimensional view of the chamber 50 of this embodiment. FIG. 4B is a cross-sectional view of the chamber 50 when viewed from the arrow direction 4B-4B shown in FIG. 4A. FIG. 5A is a cross-sectional view of the chamber 50 when viewed from the arrow direction 5A-5A shown in FIG. 4B. FIG. 5B is a cross-sectional view of the chamber 50 when viewed from the arrow direction 5B-5B shown in FIG. 4B. FIG. 6 is a three-dimensional view of the chamber 50 and the heating unit 40 of this embodiment.

As shown in FIG. 4A and FIG. 4B , the chamber 50 may have a cylindrical shape including an opening 52 into which the aroma product 110 is inserted, and a cylindrical side wall portion 60 for accommodating the aroma product 110. A flange portion 52a is formed at the end of the opening 52 that partitions the chamber 50. The chamber 50 is configured in such a manner that the flange portion 52a disposed on the opposite side of the bottom 56 faces the opening of the outer shell 101. In addition, the chamber 50 is preferably heat-resistant and formed of a material with a small thermal expansion coefficient, such as stainless steel. In addition to metal, the chamber 50 may also be formed of resins such as PEEK, glass, or ceramics. In this way, effective heating from the chamber 50 to the aroma product 110 can be performed. In addition, the chamber 50 is not limited to a cylindrical shape, but may also have a cup shape.

As shown in FIG. 4B and FIG. 5B , the side wall portion 60 includes a contact portion 62 and a partition portion 66. When the aroma product 110 is arranged at a desired position in the chamber 50, the contact portion 62 contacts or presses a portion of the aroma product 110 along the axial direction (Z-axis direction) of the chamber 50, and the partition portion 66 is separated from the aroma product 110. That is, the chamber 50 compresses and holds the inserted aroma product 110. In addition, the so-called "desired position in the chamber 50" in this specification means a position where the aroma product 110 is properly heated, or a position of the aroma product 110 when the user smokes. The contact portion 62 has an inner surface 62a and an outer surface 62b. The partition portion 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 a gap. In addition, the heating portion 40 may include a bonding layer. In this case, the heating portion 40 including the bonding layer is preferably disposed on the outer surface 62b of the contact portion 62 without a gap.

As shown in FIG. 4A and FIG. 5B , the outer surface 62b of the contact portion 62 is a plane. As shown in FIG. 6 , by making the outer surface 62b of the contact portion 62 a plane, when the strip electrode 48 is connected to the heating portion 40 disposed on the outer surface 62b of the contact portion 62, the bending of the strip electrode 48 can be suppressed. As shown in FIG. 4B and FIG. 5B , the inner surface 62a of the contact portion 62 is a plane. In addition, as shown in FIG. 4B and FIG. 5B , the thickness of the contact portion 62 is uniform.

As shown in FIG. 4A, FIG. 4B and FIG. 5B, the chamber 50 has two contact portions 62 in the circumferential direction of the chamber 50, and the two contact portions 62 are parallel to each other and face each other. The distance between at least a portion of the inner surfaces 62a of the two contact portions 62 is preferably smaller than the width of the place where the contact portions 62 of the fragrance product 110 inserted into the chamber 50 are arranged.

As shown in FIG. 5B , the inner surface 66a of the partition 66 may have an overall arc-shaped cross section in a cross section orthogonal to the axial direction (Z-axis direction) of the chamber 50. In addition, the partition 66 is arranged in a manner adjacent to the contact portion 62 in the circumferential direction. That is, the contact portion 62 and the partition 66 form a non-circular inner circumferential surface in a cross section orthogonal to the axial direction (Z-axis direction) of the chamber 50.

As shown in FIG. 4B , the chamber 50 can be arranged in the manner of penetrating the bottom member 36 shown in FIG. 3 and being arranged inside the chamber 50, and having a hole 56a in the bottom 56. In addition, the bottom member 36 can be fixed inside the bottom 56 of the chamber 50 by adhesives or the like. The adhesive interposed between the bottom member 36 and the bottom 56 can be made of a resin material such as epoxy resin. In addition, an inorganic adhesive such as cement or welding can be used instead. The bottom member 36 arranged at the bottom 56 can support a part of the fragrance product 110 inserted into the chamber 50 in a manner that at least a part of the end face of the fragrance product 110 is exposed. In addition, the bottom 56 supports a portion of the aroma product 110 in a manner that allows the exposed end surface of the aroma product 110 to communicate with the gap 67 (see FIG. 7 ) described later.

As shown in FIG. 4A, FIG. 4B and FIG. 5A, the chamber 50 preferably has a cylindrical non-retaining portion 54 between the opening 52 and the side wall portion 60. When the aroma producing product 110 is positioned at the desired position of the chamber 50, a gap can be formed between the non-retaining portion 54 and the aroma producing product 110. In addition, as shown in FIG. 4A and FIG. 4B, the chamber 50 preferably has a first guide portion 58, which has a conical surface 58a connecting the inner surface of the non-retaining portion 54 and the inner surface 62a of the contact portion 62.

As shown in FIG6 , the heating portion 40 has a heating element 42. The heating element 42 may be, for example, a heat generating resistor. The heating element 42 is preferably arranged in a manner that heats the contact portion 62 without contacting the partition portion 66 of the chamber 50. In other words, the heating element 42 is preferably arranged only on the outer surface of the contact portion 62. The heating element 42 may have a difference in heating capacity between the portion that heats the partition portion 66 of the heating chamber 50 and the portion that heats the contact portion 62. Specifically, the heating element 42 can be configured in a manner that heats the contact portion 62 to a higher temperature than the partition portion 66. For example, the arrangement density of the heat generating resistors of the heating element 42 in the contact portion 62 and the partition portion 66 can be adjusted. In addition, the heating element 42 may have substantially the same heating capacity over the entire circumference of the chamber 50 and be wound around the outer circumference of the chamber 50. As shown in FIG6 , in addition to the heating element 42, the heating portion 40 preferably has an electrical insulating member 44 made of a resin or the like covering at least one side of the heating element 42. In this embodiment, the electrical insulating member 44 is configured to cover both sides of the heating element 42.

FIG. 7 is a cross-sectional view of FIG. 5B showing a state where a fragrance product 110 is arranged at a desired position in the chamber 50 of the present embodiment. As shown in FIG. 7 , when the fragrance product 110 is arranged at a desired position in the chamber 50, the fragrance product 110 can be pressed by contacting the contact portion 62 of the chamber 50. On the other hand, a gap 67 is formed between the fragrance product 110 and the partition 66. The gap 67 can communicate with the opening 52 of the chamber 50 and the end face of the fragrance product 110 positioned in the chamber 50. Thus, the air flowing in from the opening 52 of the chamber 50 can flow into the interior of the fragrance product 110 through the gap 67. In other words, an air flow path (gap 67) is formed between the fragrance product 110 and the partition 66.

Next, for the chamber 50 of this embodiment, the specific structure of the boss corresponding to each embodiment is described.

[Example 1: Longitudinal boss]

FIG8 is a cross-sectional view of the chamber 50 of Example 1 of the present embodiment. FIG9 is a cross-sectional view of the chamber 50 shown in FIG8. Here, FIG8 is a cross-sectional view of the chamber 50 cut along the axis of the chamber 50, and shows a cross-sectional view orthogonal to the cross-sectional view shown in FIG4B. In addition, FIG9 shows a cross-sectional view corresponding to FIG5A.

As shown in Fig. 8 and Fig. 9, a convex seat 51A is formed on the inner circumference of the chamber 50, and is configured to hold the outer circumference of the aroma producing product 110 accommodated in the chamber 50 by pressing it inwardly in the radial direction of the chamber 50. The convex seat 51A is provided on the inner surface 62a of the contact portion 62 on the inner circumference of the chamber 50. In addition, the convex seat 51A is provided on each surface of the inner surface 62a facing each other. In addition, the convex seat 51A is a protrusion that protrudes from the inner circumference of the chamber 50 and presses the aroma producing product 110, and extends along the axial direction (Z-axis direction) of the chamber 50. The convex seat 51A can be formed by embossing, or can be formed by a convex member installed on the inner circumference of the chamber 50. In addition, the boss 51A may be provided on only one of the inner surfaces 62a facing each other, or a plurality of bosses 51A may be provided on one inner surface 62a.

Thus, by providing the convex seat 51A on the inner surface 62a of the contact portion 62, the aroma product 110 can be compressed and held in the chamber 50, and the aroma product 110 can be held by the convex seat 51A in the chamber 50. Therefore, even when stress acts on the aroma product 110, the aroma product 110 can be prevented from falling out of the chamber 50. In addition, by forming the convex seat 51A with a protrusion extending in the axial direction (Z-axis direction) of the chamber 50, the aroma product 110 can be stably held in the chamber 50.

In addition, when the aroma product 110 is inserted into the chamber 50, the protrusion 51A is disposed at a position that can contact at least two of the filling portion 111, the cylindrical member 114, and the filter portion 115 of the aroma product 110. For example, when the aroma product 110 is inserted into the chamber 50, the protrusion 51A first contacts the filling portion 111, and then contacts the cylindrical member 114 and the filter portion 115. Therefore, the aroma product 110 can be stably held at a position close to the insertion end of the chamber 50.

[Example 2: Horizontally elongated boss]

FIG. 10 is a cross-sectional view of the 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 is a cross-sectional view of the chamber 50 cut along the axis of the chamber 50 and shows a cross-sectional view orthogonal to the cross-sectional view shown in FIG. 4B . In addition, FIG. 11 shows a cross-sectional view corresponding to FIG. 5A .

As shown in FIG. 10 and FIG. 11 , a boss 51B is formed on the inner circumferential surface of the chamber 50, and is configured to hold the outer circumferential surface of the aroma product 110 accommodated in the chamber 50 in a manner of pressing inwardly toward the diameter of the chamber 50. On the inner circumferential surface of the chamber 50, the boss 51B is disposed on the inner surface 62a of the contact portion 62. In addition, the boss 51B is disposed on each surface of the inner surface 62a facing each other. In addition, the boss 51B is a protrusion that protrudes from the inner circumferential surface of the chamber 50 and presses the aroma product 110, and extends in a direction orthogonal to the axial direction (Z-axis direction) of the chamber 50, specifically, in a transverse direction (Y-axis direction). Similar to the first embodiment, the boss 51B can be formed by embossing, or by a convex member mounted on the inner circumference of the chamber 50. In addition, the boss 51B can be provided on only one of the inner surfaces 62a facing each other, or a plurality of bosses 51B can be provided on one inner surface 62a.

Thus, by providing the convex seat 51B on the inner surface 62a of the contact portion 62, the fragrance product 110 can be compressed and held in the chamber 50, and the fragrance product 110 can be held by the convex seat 51B in the chamber 50. Therefore, even when stress acts on the fragrance product 110, the fragrance product 110 can be prevented from falling off from the chamber 50. In addition, by forming the convex seat 51B with a protrusion extending in the lateral direction (Y-axis direction) of the chamber 50, the fragrance product 110 can be restricted from rotating around the Y-axis, so that the fragrance product 110 can be suppressed from shaking toward the partition 66.

In addition, similar to the first embodiment, by setting the protrusion 51B at a position that can contact at least two parts of the fragrance product 110, the fragrance product 110 can be stably held at a position close to the insertion end of the chamber 50.

[Example 3: Point-shaped protrusion]

FIG. 12 is a cross-sectional view of 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 is a cross-sectional view of the chamber 50 cut along the axis of the chamber 50, and shows a cross-sectional view orthogonal to the cross-sectional view shown in FIG. 4B. In addition, FIG. 13 shows a cross-sectional view corresponding to FIG. 5A.

As shown in FIG. 12 and FIG. 13 , a boss 51C is formed on the inner circumference of the chamber 50, and is configured to hold the outer circumference of the aroma product 110 accommodated in the chamber 50 by pressing it inwardly in the radial direction of the chamber 50. The boss 51C is disposed on the inner surface 62a of the contact portion 62 on the inner circumference of the chamber 50. In addition, the boss 51C is disposed on each surface of the inner surface 62a facing each other. In addition, the boss 51C is a dot-shaped protrusion that protrudes from the inner circumference of the chamber 50 and presses the aroma product 110. Similar to Embodiment 1, the boss 51C can be formed by embossing, or by a convex component installed on the inner circumference of the chamber 50. In addition, the boss 51C may be provided on only one of the inner surfaces 62a facing each other, or a plurality of bosses 51C may be provided on one inner surface 62a.

Thus, by providing the convex seat 51C on the inner surface 62a of the contact portion 62, the aroma product 110 can be compressed and held in the chamber 50, and the aroma product 110 can be held by the convex seat 51C in the chamber 50. Therefore, even when stress acts on the aroma product 110, the aroma product 110 can be prevented from falling out of the chamber 50. In addition, by forming the convex seat 51C with a dot-shaped protrusion, the aroma product 110 can be pressed and held in the chamber 50 with a simple structure.

In addition, similar to the first embodiment, by setting the protrusion 51C at a position that can contact at least two parts of the fragrance product 110, the fragrance product 110 can be stably held at a position close to the insertion end of the chamber 50.

[Experimental results]

Various experiments were conducted using the aroma inhaler using the chamber 50 of Examples 1 to 3 of the present embodiment described above and the aroma inhaler of Comparative Examples 1 to 3. The experimental results are described below.

[Sample preparation]

First, a smoking system consisting of a combination of a flavor product and a flavor inhaler as shown in Table 1 is prepared. Here, the test inhaler 1 of sample 1 has the chamber 50 of the above-mentioned embodiment 1 (refer to Figures 8 and 9). The test inhaler 2 of sample 2 is the same flavor inhaler as sample 1 except that it has the chamber 50 of the above-mentioned embodiment 2 (refer to Figures 10 and 11). The test inhaler 3 of sample 3 is the same flavor inhaler as sample 1 except that it has the chamber 50 of the above-mentioned embodiment 3 (refer to Figures 12 and 13).

In addition, the scent inhalers of samples 4 to 6 are commercially available Ploom S 2.0, Ploom and glo hyper (glo is a registered trademark). In addition, the scent product products in samples 1 to 5 are manufactured specifically for testing inhalers 1 to 3, Ploom S2.0 and Ploom (sold in Russia and the UK). In addition, the scent product product in sample 6 is a commercially available product specifically for glo hyper.

Here, the relationship between the scent product in samples 1 to 3 and the test inhalers 1 to 3 is equivalent to, for example, a combination of a consumable and a device set. This combination includes: a consumable including the scent product in samples 1 to 3, and a device set including any one of the test inhalers 1 to 3 of samples 1 to 3; and at least one of the consumable and the device set has a mark indicating that it is to be used in the other of the consumable and the device set. That is, the consumable is a special product for the device set. In addition, the mark includes, for example, "for X", "for X", "designed for X" (X is a brand or product name, etc.). In addition, the consumable includes the packaging of the consumable, and the device set includes, for example, packaging or product instructions.

[Table 1]

[Method for measuring resistance value]

For each sample, the resistance value (insertion resistance) when inserting the fragrance product into the fragrance inhaler was measured using EZ-S500N (hereinafter referred to as the device) manufactured by Shimadzu Corporation. Specifically, the fragrance inhaler was first mounted on the fragrance inhaler auxiliary tool (jig, also referred to as the jig) mounted on the device. Then, one end of the fragrance product (the end on the non-interface side) was inserted into the fragrance inhaler to such an extent that the fragrance product would not shake. Then, the insertion auxiliary tool was brought into contact with the other end of the fragrance product (the end on the interface side). Then, the resistance value of the device was zero-calibrated.

Then confirm that the aroma inhaler and the aroma product are not tilted, and lower the push-in auxiliary tool. The stroke speed of the push-in auxiliary tool at this time is set to 60mm/min. In addition, the test conditions are temperature 25℃ and humidity 20%. In addition, in this device, the sampling length is set to 50msec. In this case, the length of one interval of the acquired data becomes 0.05mm. Then lower the push-in auxiliary tool to a predetermined length. Once the movement of the push-in auxiliary tool stops, the test ends. The above measurement is performed twice on each sample.

[Obtaining resistance value]

The average value of the two measurement results for each sample is set as the resistance value. In this case, first, in each measurement result, the position when the front end of the fragrance product reaches the end position of the chamber is determined, and the two measurement results are integrated based on the determined position to obtain the average value. Then, each value is obtained with a range of 10 mm from the end position of the chamber as the object. That is, the insertion force, average resistance, local resistance, local resistance position and minimum resistance described below are obtained in a range of 10 mm from the end position of the chamber.

Figures 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 Figures 14 to 19, the position of the press-in aid corresponding to the end position of the chamber is displayed as 0, the position before reaching the end position is displayed as a positive value, and the position after reaching the end position is displayed as a negative value. For example, the position of +10mm in Figures 14 to 19 means the position 10mm before the end position in the insertion direction of the fragrance product.

Here, the so-called "position when reaching the end position of the chamber" (hereinafter also referred to as the end position) means that among the resistance values measured by the above method, when the difference between the resistance value of a certain section and the previous section (that is, the difference in the resistance value between 0.05mm) becomes 0.1N or more, the section covers an area that exists continuously for 0.5mm, and is set as the position on the previous section of the area.

[Insertion force]

From the data of the resistance values obtained by the above method, the insertion force of each sample is obtained. The insertion force here refers to the resistance value when the front end of the fragrance product reaches the end position of the chamber.

[Average resistance]

From the data of resistance values obtained by the above method, the average resistance of each sample is obtained. Here, the average resistance of the first half and the average resistance of the second half are evaluated. The so-called average resistance of the first half means the average of the resistance values in the range of 10mm to 5mm from the end, and the so-called average resistance of the second half means the average of the resistance values in the range of 5mm to 0mm from the end. In addition, the ratio of the average resistance of the second half to the average resistance of the first half (second half/first half) is also called the first resistance ratio.

[Local resistance and local resistance location]

From the data of the resistance value obtained by the above method, the local resistance and the local resistance position of each sample are obtained. The so-called local resistance here means that in the local change area where the resistance value changes by more than a predetermined amount within a predetermined range, specifically, when there are local rises and local falls in sequence in a continuous range of 1.0mm, the resistance value becomes the maximum in the area between the first local rise and the last local fall. In addition, the so-called local rise means that the resistance value rises by more than 0.1N in two consecutive intervals. In addition, the so-called local fall means that the resistance value drops by more than 0.05N in two consecutive intervals. In addition, the ratio of local resistance to insertion force is called the second resistance ratio. In addition, the so-called local resistance position refers to the position away from the end position of the chamber when the local resistance is generated, that is, the distance from the end position of the chamber to the position where the local resistance is generated.

[Minimum resistance]

From the data of resistance values obtained by the above method, the minimum resistance of each sample is obtained. The minimum resistance here refers to the minimum resistance value between the local resistance position and the end position of the chamber.

The insertion force, average resistance, local resistance, local resistance position and minimum resistance obtained for each sample 1 to 6 are shown in Table 2.

[Table 2]

[Sensory Assessment]

For each of samples 1 to 6, five trained judges with identification ability conducted sensory evaluations on whether it was easy to feel that the fragrance product had reached the end of the cavity when it was inserted into the cavity, and whether it was easy to foresee reaching the end of the cavity. In addition, those who easily felt that they had reached the end of the cavity were also called those who had a sense of reaching the end, and those who easily foresaw reaching the end of the cavity were also called those who had a sense of foreseeing reaching the end.

[Sensory evaluation of sample 6]

First, regarding the sense of end arrival, five evaluators used sample 6 and evaluated the degree to which the front end of the fragrance product reached the end of the chamber by consensus. The evaluation criteria are as follows.

‧It is difficult to feel the end has been reached.

‧You can feel the end is reached.

Next, regarding the sense of foreseeable arrival at the end, five assessors used sample 6 and evaluated the degree to which the front end of the scent product was expected to reach the end of the chamber by consensus of the assessors. The evaluation criteria are as follows.

‧It is difficult to predict the end.

‧The arrival of the end can be foreseen.

According to the evaluation results of the evaluators, sample 6 makes people feel that the front end of the fragrance product has reached the end of the chamber, but on the other hand, it is difficult for people to foresee that the front end of the fragrance product has reached the end of the chamber.

[Sensory evaluation of samples 1 to 5]

Next, regarding the sense of arrival at the end, the same five assessors used samples 1 to 5, scored 3 points for sample 6 and evaluated on a 5-point scale of 1 to 5, and independently gave scores for the degree to which they felt the front end of the fragrance product had reached the end of the chamber, and calculated the average. The evaluation criteria are as follows.

5 points: It is easy to feel the end has been reached.

4 points: It is slightly easy to feel the end.

3 points: No change.

2 points: It is slightly difficult to feel the end.

1 point: It is difficult to feel the end.

Next, regarding the sense of foreseeable arrival at the end, the same five assessors used samples 1 to 5, with sample 6 being 3 points and evaluating on a 5-step scale of 1 to 5 points, and independently gave scores for the degree to which the front end of the fragrance product could be foreseen to reach the end of the chamber, and calculated the average. The evaluation criteria are as follows.

5 points: It is easy to foresee the arrival of the end.

4 points: It is slightly easy to foresee the arrival of the end.

3 points: No change.

2 points: It is slightly difficult to predict the arrival of the end.

1 point: It is difficult to predict the end.

The results of evaluating the sense of terminal arrival and the sense of foreseeable terminal arrival for each sample 1 to 6 are shown in Table 3.

[Table 3]

[Discussion of results]

As shown in Table 2, since the insertion force of samples 1 to 3 is less than 4.00N, when inserting the fragrance product into the cavity, it can be felt that the end of the cavity has been reached. In addition, since the first resistance ratio of samples 1 to 3 is greater than 1.0, the rising feeling of the insertion resistance on one side close to the end of the cavity can make people feel the approach of the end and easily foresee reaching the end of the cavity. In addition, since a local variable area is provided in samples 1 to 3, it is easy for users to feel the approach of the end of the cavity and it is easier to foresee reaching the end of the cavity.

In fact, as shown in Table 3, the evaluations of the sense of end arrival and the sense of anticipation of end arrival of samples 1 to 3 are all over 3 points. Therefore, it can be confirmed that samples 1 to 3 all have the sense of end arrival and the sense of anticipation of end arrival, that is, they have both the sense of end arrival and the sense of anticipation of end arrival. This can be considered that in samples 1 to 3, the resistance feeling when the fragrance product is inserted is small, so it is easy to get the sense of end arrival. In addition, as shown in Figure 15, in sample 2, it can be considered that the resistance value decreases after the resistance value increases in the local variable area, so it is easy to get the sense of end arrival. In addition, in samples 1 to 3, it can be considered that when the fragrance product is inserted, it feels stuck once, and then it feels that it reaches the end of the cavity when it is pressed again, so it is easy to get the sense of anticipation of end arrival.

In addition, from the perspective of suppressing the falling of the fragrance product, the lower limit of the insertion force is preferably 0.50N or more, more preferably 0.70N or more, and more preferably 1.00N or more. In addition, from the perspective of ease of insertion, the upper limit of the insertion force is preferably 3.00N or less, and more preferably 2.00N or less. In addition, from the perspective of easy to obtain the sense of terminal arrival, the lower limit of the first resistance ratio is preferably 1.0 or more, and more preferably 1.05 or more. In addition, the upper limit of the first resistance ratio is preferably 2.0 or less, and more preferably 1.8 or less.

In addition, as shown in Table 2, since the second resistance ratio of the resistance value in the local change area to the insertion force of samples 2 and 3 is greater than 0.8, the resistance value in the local change area is significantly smaller than the insertion force, so the failure to help predict the end of the cavity can be suppressed.

In fact, as shown in Table 3, the evaluations of the sense of end arrival and the sense of anticipation of end arrival of samples 2 and 3 are both over 4 points. Therefore, it can be confirmed that samples 2 and 3 both have the sense of end arrival and the sense of anticipation of end arrival, that is, they have both the sense of end arrival and the sense of anticipation of end arrival, especially the sense of high anticipation of end arrival. This phenomenon can be considered when referring to Figures 14 to 16. In samples 2 and 3, after feeling stuck once when inserting the fragrance product, the resistance value is smaller than that of sample 1, so it is easier to get the sense of anticipation of end arrival.

In addition, the upper limit of the second resistance ratio is preferably less than 1.0. When there is a resistance value greater than the insertion force in the local change area, there is a concern that the user will feel strange, and there is also a concern that the user will mistake the local change area for the end position of the chamber. In addition, when there is an excessively large local resistance value, there is a concern that the fragrance-producing product will bend in the local change area. In addition, from the perspective of allowing the user to foresee the arrival of the end through the local resistance, the lower limit of the second resistance ratio is preferably greater than 0.8, and more preferably greater than 0.9.

In addition, as shown in Table 2, since the distance from the end position of the chamber to the local change area of sample 3 is less than 5.0 mm, the user can maintain the feeling of having passed the local change area until reaching the end of the chamber, and it is easier to foresee reaching the end of the chamber.

In fact, as shown in Table 3, the evaluation of the sense of terminal arrival and the sense of foreseeing terminal arrival of sample 3 is the highest among samples 1 to 3. Therefore, it can be confirmed that sample 3 obtains both the sense of terminal arrival and the sense of foreseeing terminal arrival, and has both the sense of terminal arrival and the sense of foreseeing terminal arrival, and especially obtains an extremely high sense of foreseeing terminal arrival.

In addition, the upper limit of the distance from the end position of the cavity to the local variable area is preferably less than 6.5 mm, and more preferably less than 6.0 mm. In addition, from the perspective of preventing the user from reaching the end of the cavity before the end position of the cavity is close to the local variable area and feeling that the user has passed through the local variable area, the lower limit of the distance from the end position of the cavity to the local variable area is preferably more than 2.0 mm, more preferably more than 3.0 mm, and even more preferably more than 3.5 mm.

On the other hand, since the insertion force of samples 4 and 5 is relatively large, it is difficult to feel that the front end of the fragrance product has reached the end of the cavity, and it is difficult to foresee that it has reached the end of the cavity. In addition, as mentioned above, although the front end of the fragrance product can be felt to have reached the end of the cavity in sample 6, it is difficult to foresee that the front end of the fragrance product has reached the end of the cavity.

The above is an explanation of the implementation form of the present invention, but the present invention is not limited to the above implementation form. Various modifications can be made within the scope of the patent application and the technical ideas described in the specification and drawings. In addition, any shape or material that is not directly described in the specification and drawings is within the scope of the technical ideas of the present invention as long as it achieves the function and effect of the present invention.

For example, the aroma inhaler 100 of the present embodiment has a so-called counter-flow air flow path in which the air flowing in from the opening 52 of the chamber 50 is supplied to the end surface of the aroma product 110, but is not limited thereto, and may also have a so-called bottom-flow air flow path in which the air is supplied from the bottom 56 of the chamber 50 to the inside of the chamber 50. In addition, the heating element 42 is not limited to the resistive heating type, but may also be an inductive heating type. In this case, the heating element 42 may heat the chamber 50 by inductive heating. In addition, the aroma product 110 may also have a heater as a heating element. In this case, the aroma inhaler 100 does not have a heating element inserted into the aforementioned aroma product, but a heater as a heating element exists inside the aroma product 110. In addition, the heating element 42 is arranged around the chamber 50 to increase the temperature of the aroma generating product 110 in the chamber 50. However, the method of increasing the temperature of the aroma generating product 110 in the chamber 50 can also be to directly contact the heating element 42 with the aroma generating product 110, or to generate friction heat by vibration of the substances in the aroma generating product 110.
