Description

Non-heated flavor aspirator

The present invention relates to a non-heated flavor inhaler that provides flavor components to a user without requiring combustion or heating.

In recent years, non-heated flavor inhalers that provide flavor components to users without requiring combustion or heating have been provided (for example, Patent Document 1 and Patent Document 2). The non-heating type flavor suction device of patent document 1 is provided with the hollow suction holder which has a suction mouth, and the filling body (flavor component) arrange | positioned in a suction holder.

Further, the non-heated flavor suction device of Patent Document 2 includes a hollow suction holder having a suction port, and a pouch disposed in the suction holder. The pouch includes a granular tobacco raw material that divides the air flow path in the suction holder into an upstream region and a downstream region and releases a flavor component therein.

According to the non-heated flavor inhalers of Patent Document 1 and Patent Document 2, the user can suck the flavor components filled inside by sucking air from the suction port of the suction holder.

However, the above-mentioned non-heated flavor inhaler has the following problems. The non-heating type flavor suction device of patent documents 1 and 2 requires the suction holder for accommodating a filling body and a pouch. The suction holder is a hard part that can be used repeatedly. For this reason, the suction port of the suction holder must always be managed hygienically, but such management is troublesome for the user.

In recent years, a thin flavor inhaler excellent in portability has been demanded. However, a suction holder made of hard parts cannot be thinly deformed by the user, and it is difficult to improve portability.

However, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones.

Therefore, specific dimensions should be determined in consideration of the following explanation. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.

(1) Overall Schematic Configuration of Non-Heating Type Flavor Inhaler The non-heating type flavor inhaler 10 includes a flavor generating source 20, a bag body 30, and an exterior body 40. In the non-heating type flavor inhaler 10, the bag body 30 containing the flavor generation source 20 is surrounded by the exterior body 40, and an opening 41 formed at the outer end in the axial direction of the cylindrical exterior body 40, The flavor component contained in the flavor generating source in the bag body 30 can be sucked through 42.

The non-heating type flavor inhaler 10 is configured to be deformed into a thin state when being carried and into a cylindrical state when being used. FIGS. 1 to 3 show the non-heated flavor inhaler 10 in a state before deformation when being carried, and FIGS. 4 to 6 show the non-heated flavor inhaler 10 in a state after deformation at the time of use. Show.

FIG. 1 is an overall schematic configuration diagram of a non-heated flavor inhaler 10 before deformation. 2 is a cross-sectional view taken along the line AA shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line BB shown in FIG. FIG. 4 is an overall schematic configuration diagram of the non-heated flavor inhaler 10 after deformation. 5 is a cross-sectional view taken along the line CC shown in FIG. 4, and FIG. 6 is a cross-sectional view taken along the line DD shown in FIG.

The flavor generating source 20 is a powder that generates flavor components, and is not particularly limited. Specifically, for example, tobacco leaf can be used, and tobacco materials such as general chopped tobacco used for cigarettes (cigarettes), granular tobacco used for snuff, rolled tobacco, or molded tobacco are adopted. be able to. In addition to tobacco leaves, flavor components such as menthol may be used.

The bag body 30 contains the flavor generating source 20. The bag body 30 is made of a material having air permeability and flexibility. Air permeability should just be comprised so that passage of the flavor component of the flavor generation source 20 which air can pass and is included is possible. The flexibility is only required to be deformable when the user holds the non-heated flavor inhaler with a finger or the like. The bag 30 according to the present embodiment is constituted by a nonwoven fabric having a basis weight of 25 g / m ² . In addition, the bag body 30 should just have air permeability and the above-mentioned flexibility, and a woven fabric and a porous sheet material other than a nonwoven fabric can be used.

The bag 30 is formed, for example, by folding a sheet-like nonwoven fabric. Specifically, the sheet-like nonwoven fabric is folded based on the fold along the axial direction X of the non-heating type flavor inhaler, and the end portions of the sheet-like nonwoven fabric are joined by heat welding or the like to form two layers. A space for enclosing the flavor generating source 20 is formed between the nonwoven fabrics.

The bag body 30 has a rectangular shape having a first side 31 along the axial direction in a folded state and a pair of second sides 32 along the width direction orthogonal to the first side 31. In the bag body 30, the nonwoven fabrics are joined so that the nonwoven fabrics that overlap in the folded state are continuous at the first side 31 and the second side 32. The flavor generating source 20 can be included by the bag body 30 configured as described above.

The user sucks air from the outside of the bag body 30 through the opening of the exterior body 40, and sucks the flavor component contained in the flavor generation source 20 through the bag body 30. Therefore, the nonwoven fabric which comprises the bag body 30 requires the air permeability for a user to attract | suck air easily, and the fineness of the eyes since the flavor generation source 20 does not flow out.

The volume of the flavor generation source 20 enclosed in the bag body 30 is smaller than the volume of the bag body 30 (the volume capable of accommodating the flavor generation source 20). Thus, the flavor generating source 20 is movable in the bag 30 by enclosing the flavor generating source 20 in the bag 30. For example, the volume of the flavor generation source 20 enclosed in the bag body 30 is smaller than a predetermined volume that is smaller than the volume of the bag body 30. In addition, as described above, the bag body 30 is made of a flexible material, and the exterior body 40 is flexible so as to be deformed as will be described later. Therefore, it may be considered that the volume of the bag body 30 is increased with the deformation of the bag body 30 and the exterior body 40, and the flavor generating source 20 is easily moved in the bag body 30.

For example, when the volume of the flavor generation source 20 and the volume of the bag body 30 are substantially the same, the flavor generation source 20 is difficult to move within the bag body 30 and the bag body 30 is difficult to deform. However, since the flavor generation source 20 is movable in the bag body 30, the user can easily change the shape of the bag body 30. The exterior body 40 is arrange | positioned so that the bag body 30 may be enclosed, and it is comprised so that a deformation | transformation into a cylinder shape is possible. The exterior body 40 is folded so that one sheet material surrounds the periphery of the bag body 30. The exterior body 40 has flexibility that can be deformed into a cylindrical shape around the bag body 30. The flexibility is only required to be deformable when the user holds the non-heated flavor inhaler with a finger or the like. The exterior body 40 according to the present embodiment is made of paper having a basis weight of 65 g / m ² . Moreover, if the air permeability of the exterior body is too high, air flows from the periphery of the exterior body into the bag body during suction, and there is a possibility that the air flow rate to the flavor generation source is reduced. Therefore, the exterior body 40 only needs to have the above-described flexibility and low air permeability so as not to hinder the inflow of air to the flavor generation source. A quality sheet material can be used.

The exterior body 40 is folded based on a pair of fold lines (first fold line L1 and second fold line L2) along the first side 31 of the bag body 30. A pair of openings 41 and 42 are formed at both ends in the axial direction of the exterior body 40 in a state where the exterior body 40 is folded at the crease. A gap 43 is provided between the pair of openings 41 and 42 in a state where the exterior body 40 is folded with the first fold line L1 and the second fold line L2 as base points. This gap 43 is a first fold that is folded based on the intermediate area CA positioned between the first fold line L1 and the second fold line FA2 of the exterior body 40 and the first fold line L2 of the exterior body 40 in a state before being folded. It is formed between the area FA. The bag body 30 is accommodated in the gap 43. The bag body 30 is disposed in the exterior body 40 in a deformable state in the exterior body 40.

A part of the bag body 30 and a part of the exterior body 40 are joined. In FIG. 1 etc., the joining part 50 in which a part of the bag body 30 and a part of the exterior body 40 are joined is illustrated. Both the exterior body 40 and the bag body 30 have flexibility and are configured to be appropriately deformable by the user. For example, when the exterior body 40 and the bag body 30 are not joined, the bag body 30 may come off from the exterior body 40, or the positions of the exterior body 40 and the bag body 30 may be shifted, thereby stabilizing the user. Then, there is a possibility that the flavor component cannot be sucked. However, by providing the joint portion 50, the bag body 30 is prevented from coming off from the outer package 40, and the positions of the outer package 40 and the bag body 30 are prevented from being displaced, thereby enabling stable suction. It becomes.

A part of the bag body 30 and a part of the exterior body 40 are joined at the joint 50. Examples of the bonding method of the bonding portion include heat welding (heat sealing) and an adhesive, and various bonding methods can be used. For example, when heat sealing is employed as the bonding method of the bonding portion, since an adhesive is not used, there is an advantage that the manufacturing process can be simplified. On the other hand, when an adhesive such as carboxymethylcellulose is employed, a cellulose-based material that does not have heat sealability can be used as the bag body 30 and the exterior body 40, and it has the advantage of high manufacturing suitability.

The joint portion 50 of the present embodiment is a state in which the exterior body 40 is folded from the first fold line L1 and the exterior body 40 is folded from the second fold line L2 to the base point by heat sealing. The bag body 30 is joined. Specifically, the intermediate area CA of the exterior body 40 and the bag body 30 are joined, and the first folding area FA of the exterior body 40 and the bag body 30 are joined. The joint portion 50 has a linear shape extending along the width direction Y orthogonal to the axial direction X, and is provided with an interval in the axial direction X.

The joint portion 50 is located on the inner side in the axial direction than the second side 32 that is the outer end portion in the axial direction of the bag body 30. For example, when the joint portion is positioned at the axial end of the bag body 30, the bag body may be deformed from the state before deformation (folded state) to the state after deformation (cylindrical state). The two layers of non-woven fabric are not separated from each other at 30 axial ends, and cannot be deformed into a cylindrical shape. However, since the joint portion is located on the inner side in the axial direction from the outer end portion in the axial direction of the bag body 30, the exterior body 40 and the bag body 30 can be deformed into a cylindrical shape.

(2) Usage Mode of Non-heating Type Flavor Inhaler Next, usage modes of the non-heating type flavor inhaler 10 thus configured will be described. The non-heated flavor inhaler 10 is configured to be carried by the user in the state shown in FIG. 1 (folded state) and transformed into the state shown in FIG. 4 when used. Specifically, for example, the user holds the first fold line L1 and the second fold line L2 of the folded exterior body 40 with a finger, and the exterior body so that the first fold line L1 and the second fold line L2 approach each other. 40 is pressed. By pressing the exterior body 40 with a finger in this manner, the exterior body 40 and the bag body 30 are deformed, and a gap 43 is formed between the intermediate area CA of the exterior body 40 and the first folding area FA of the exterior body 40. Is done. By deforming in this way, as shown in FIG. 6, the cross-sectional shapes of the exterior body 40 and the bag body 30 become substantially circular. A gap 43 between the intermediate area CA of the exterior body 40 and the first folding area FA of the exterior body 40 serves as an air flow path through which air can pass.

At this time, the bag body 30 includes an intermediate area CA between the first fold line L1 and the second fold line L2 of the exterior body 40 and a first fold area FA between the first fold line L1 and the second fold line L2. It is joined. Therefore, the bag body 30 is also deformed following the deformation of the intermediate area CA and the first folding area FA of the exterior body 40. Therefore, the bag body 30 is arrange | positioned along the inner surface of an exterior body.

In a state in which the outer body 40 and the bag body 30 have substantially circular cross-sectional shapes, the user sucks air using one opening (for example, the opening 41) of the outer body 40 as a suction port. Thereby, air flows into the space | gap 43 of an exterior body from the other opening part (for example, opening part 42). Since the bag body 30 is joined to the inner surface of the exterior body via the joint portion 50, the air passing through the gap 43 of the exterior body 40 passes through the bag body 30 and is disposed in the bag body 30. The flavor component contained in the flavor generation source 20 is given to the user.

For example, when the bag body 30 is separated from the exterior body 40, a flow path that passes through the bag body 30 and a flow path that does not pass through the bag body 30 are formed as an air flow path inside the exterior body. The air passing through the flow path passing through the bag body 30 can impart a flavor component to the user. However, the flow path that does not pass through the bag body 30 cannot impart a flavor component to the user. Therefore, it is desirable to increase the flow path that passes through the bag body 30 as the air flow path inside the exterior body and reduce the flow path that does not pass through the bag body 30.

The flow path that does not pass through the bag body 30 is formed in a portion where the inner surface of the exterior body 40 and the bag body 30 are separated from each other. Therefore, by providing the joint portion 50 so that the bag body 30 is disposed along the inner surface of the exterior body, the number of flow paths that do not pass through the bag body 30 is reduced, and the bag body 30 in the air flow path in the exterior body 40 is reduced. It is possible to increase the ratio of the passage (passage that contributes to the supply of flavor components) that passes through.

FIG. 7 is a state schematically showing a state in which the user sucks in the cross section shown in FIG. When the user sucks air through the opening, the flavor generation source 20 in the bag body 30 gathers on the opening side serving as a suction port. FIG. 7 shows a filling portion 33 in which the flavor generating sources 20 are filled in a state where all the flavor generating sources 20 are collected on one end side of the bag body 30 in the axial direction. The filling portion 33 is a portion where the flavor generating source 20 is filled in a state where the user sucks air from the opening and all the flavor generating sources are gathered on the opening side.

The filling portion 33 of the bag body 30 and the exterior body 40 are joined. For example, even when the bag body 30 and the exterior body 40 are joined, if there is a flow path that does not pass through the flavor source 20 in the air flow path that passes in the axial direction in the bag body 30, A flavor component cannot be provided to the user. However, since the filling part 33 and the exterior body 40 are joined together, the air passing through the bag body 30 passes through the flavor generation source 20 at the location where the bag body 30 and the exterior body 40 are in close contact, and the flavor component. Can be granted.

In the bag body 30 of the present embodiment, the flavor generating source 20 is arranged in a space formed between two layers of nonwoven fabric, and the two layers of nonwoven fabric are joined on a pair of two sides. Therefore, the cross section shown in FIG. 5 is a dogleg shape that becomes narrower toward the opening, and the area of the cross section becomes smaller toward the opening. Therefore, when the user inhales air from the opening, the flavor generation source 20 gathers at the front end side of the bag shape of the bag. The bag body 30 is joined to the exterior body 40 at joint portions provided on the upper side (first end portion side of the exterior body 40) and the lower side (intermediate side of the exterior body 40) shown in FIG. The cross-sectional shape of the bag body 30 is substantially a U-shape.

Moreover, when the joining means which joins a filling part and the exterior body 40 is a heat seal, the flavor generation source 20 can be arrange | positioned in the position which heat-seals by performing a heat seal in the state collected on the opening part side. . For example, if the flavor generating source 20 is not disposed inside the bag body 30 at a position where heat sealing is performed, the nonwoven fabrics constituting the bag body may be joined when heat sealing is performed. However, by providing a joint at a position where the filling portion of the bag body 30 and the exterior body 40 are joined, joining of the nonwoven fabrics constituting the bag body 30 can be prevented.

Further, the outer end portion in the axial direction of the bag body 30 is located on the inner side in the axial direction from the outer end portions (openings 41 and 42) in the axial direction of the exterior body 40. According to such a configuration, since the openings 41 and 42 of the exterior body 40 and the bag body 30 are separated from each other, it is possible to prevent the user's mouth from directly touching the bag body 30 when the user sucks.

(3) Modification of joint
Next, a modified example of the joint portion 50 in which the exterior body and the bag body are joined will be described. The joining part 50 should just be joined to a part of bag body 30 and a part of exterior body 40, and is not limited to the structure of the above-mentioned embodiment. For example, although the junction part which concerns on embodiment is provided in two places at intervals in the axial direction, it may be provided in one place and may be provided in three or more places. . In the case where there is only one joint, it may be provided at the center in the axial direction of the bag body 30 or may be provided closer to the suction port than the center in the axial direction of the bag body 30. For example, by providing the joint portion closer to the suction port than the center of the bag body 30 in the axial direction, the portion where the flavor generation source 20 gathers when the user sucks can be joined to the exterior body 40, and the flavor component can be efficiently applied. . Moreover, the exterior body 40 and the bag body 30 can be made to adhere | attach continuously in an axial direction by providing a junction part in three or more places at intervals in the axial direction.

FIG. 8 shows a non-heating type flavor inhaler 10A according to a modification. FIG. 8A is a schematic perspective view of the non-heating type flavor inhaler 10A, and FIG. 8B is a view showing a state after the EE section of FIG. 8A is deformed. A plurality of joint portions 50A extending in the axial direction X are provided in the non-heating type flavor inhaler 10A shown in FIG. The joint portions are provided at intervals in the circumferential direction of the exterior body 40.

The bag body 30 and the exterior body 40 are joined at a plurality of locations spaced in the circumferential direction. Since the joint portions in the circumferential direction are held in the adjacent joint portions, a state in which the bag body 30 and the exterior body 40 are substantially in close contact with each other can be realized.

In addition, as for the junction part which concerns on a modification, although the linear junction part extended in an axial direction is provided with two or more intervals in the circumferential direction, for example, there are a plurality of dot-like junction parts at intervals in the circumferential direction. It may be provided, or a plurality of wavy joints may be provided at intervals in the circumferential direction.

Moreover, although the joint part which concerns on a modification is arrange | positioned along the axial direction, you may arrange | position with inclination with respect to the axial direction. A plurality of joints inclined with respect to the axial direction may be provided, and the joints may be arranged so as to cross each other.

Furthermore, the joint portion includes a joint portion extending in the width direction and a joint portion extending in the axial direction, and these joint portions may intersect each other. Moreover, the planar shape which covers the whole fixed area | region may be sufficient as a junction part. However, the joints arranged intermittently, such as line-shaped or dot-shaped joints, rather than the planar joints, have a larger area than the joints due to the smaller joint area. The body 30 can be brought into close contact.

(4) Example Next, the Example of a non-heating type flavor suction tool is described.

(4.1) Preparation of sample A sample according to an example and a sample according to a comparative example were prepared under two conditions by the following method.

(4.1.1) Bag body Non-woven fabric (HOP25H made by Hirose Paper) is folded and joined by thermal welding as shown in Fig. 9 (a), so that the size in the width direction is 12mm x the length in the axial direction is 55mm. A bag was produced.

(4.1.2) Flavor Generation Source A powder body in which 7% menthol per weight of tobacco leaf was added to tobacco leaves was used as a flavor generation source, and 370 mg (Wet-base) was filled in the bag.

(4.1.3) Exterior Body Single-sided laminated paper (basis weight 65 g / m ² , PE laminate thickness 15 um) was used. The paper size is 38.5mm wide x 60mm long. A pressure line was provided so as to be roughly divided into three parts.

(4.1.4) Joining portion As shown in FIG. 9 (b), the sample according to the example heats the upper and lower surfaces at positions 10 mm from both ends of the exterior body after the bag body is installed on the exterior body. The outer package and the bag were fixed by welding. At the time of heat welding, adjustment was made so that a flavor generating source was filled in the bag body directly below the heat welding portion so that the bag body itself was not joined on the inner surface, and heat welding was performed. On the other hand, in the sample according to the comparative example, the bag body was arranged on the exterior body, and the bag body was simply wrapped with the exterior body without performing heat welding.

(4.1.5) Folded shape In order to evaluate the influence of the deformation of the non-heated flavor inhaler accompanying the use of the user, the sample according to the above-mentioned example and the sample according to the comparative example are condition A having different folding modes. And under condition B. In the sample according to condition A, the exterior body and the bag body were folded by the method described above. In the sample according to Condition B, the sample under Condition A was further diffracted once based on the crease along the axial direction, and then the shape was restored.

(4.2) Experimental method In order to verify the effect of flavor stabilization, the measuring apparatus 100 shown in FIG.9 (c) was used. When the user sucks the non-heated flavor inhaler 10, the measuring device measures the amount of menthol delivered to the user of the non-heated flavor inhaler 10.

Specifically, the measuring apparatus 100 includes an impinger 101 containing 20 ml of ethanol. Specifically, a Kinoshita-type gas absorption cleaning bottle (standard type 50 ml) manufactured by Kinoshita Rika Kogyo Co., Ltd. was used for the impinger 101. The impinger 101 has filter particles (100 to 200 μm) inside thereof, and has a suction tube 102 and a delivery tube 103 respectively led out from the inside.

The non-heating type flavor suction device 10 to be verified can be connected to the suction tube 102. The delivery pipe 103 is connected to a suction pump 106 via an electromagnetic valve 104 and a mass flow controller (MFC) 105. Further, a valve controller (VC) 107 is electrically connected to the electromagnetic valve 104. The valve controller 107 controls the opening / closing operation of the electromagnetic valve 104.

By the opening / closing operation by the valve controller 107, the solenoid valve 104 realizes an operation of connecting the suction pump 106 and the impinger 101 and an operation of releasing the impinger 101 to the atmosphere. Specifically, this suction cycle is repeated by setting the operation of connecting the suction pump 106 and the impinger 101 for 4 seconds and then releasing the impinger 101 to the atmosphere for 11 seconds as one suction cycle. The flow rate of the mass flow controller 105 is set to 3300 cc / min.

As the non-heated flavor inhaler 10 to be verified, a sample according to an example in which a bag body was joined to an exterior body and a sample in a comparative example in which the bag body was not joined to the exterior body were prepared.

After connecting one non-heated flavor inhaler, which is a sample, to the suction tube 102 of the impinger 101, the above suction cycle is repeated 10 times in an environment of room temperature 22 ° C. and humidity 60%, and sent out from the tobacco product. The menthol was collected in ethanol in the impinger 101.

Thereafter, the ethanol from which the menthol was collected was taken out from the impinger 101, the taken-out ethanol was analyzed with a gas chromatograph mass spectrometer, and the amount of menthol delivered per one suction cycle from the non-heated flavor inhaler was measured.

Furthermore, the above collection and analysis measurements were repeated until the total number of suction cycles reached a predetermined number (three times), thereby completing the measurement process for one non-heated flavor inhaler.

(4.3) Experimental results The experimental results are shown in FIG.

In both condition A and condition B, the sample according to the example had a higher amount of menthol than the sample according to the comparative example. In the condition A, it is considered that the sample according to the comparative example in which the bag body is not joined to the exterior body has a random bias of the flavor generation source in the bag body, and the delivery of the flavor component is unstable. On the other hand, the sample according to the example in which the bag body is joined to the exterior body, the bag body is disposed along the exterior body, the random bias of the flavor generation source is reduced in the bag body, and the delivery of flavor components is stabilized Conceivable.

In addition, in condition B, the amount of delivery of both the sample according to the example and the sample according to the comparative example is reduced, but the reduction rate of the sample according to the example is about 10%, whereas in the comparative example The reduction rate of such samples is more than half. As a result, it was found that the flavor component can be stabilized by providing the joint portion, particularly at the time of deformation due to folding.

(5) Actions / Effects As described above, according to the non-heating type flavor inhaler according to the present embodiment, since it is configured to be deformable into a compactly folded state and a cylindrical state, it is thin when carried. Folding and portability can be improved.

Also, in recent years, there has been a demand for improvement in ease of holding and gripping, and it is desired to transform the mouthpiece, handle, and the like into their favorite forms. Since the exterior body and the bag body according to the present embodiment can be freely deformed by the user according to preference, the user's satisfaction can be enhanced.

Furthermore, since the bag body and the exterior body are joined at the joint portion, the bag body can be deformed following the deformation of the exterior body, and the exterior body and the bag body are connected at the place where the joint portion is provided. It can be made to adhere substantially. Therefore, among the air flow paths in the exterior body, the flow paths that do not pass through the bag body can be reduced, and the flow paths that pass through the bag body can be increased. Therefore, in the configuration in which the flavor generating source is not filled in the bag, the ratio of the air touching the flavor generating source can be increased, and a stable supply of flavor components can be realized.

Since the filling portion of the bag body and the exterior body are joined, the air passing through the bag body at the time of suction can easily touch the flavor generation source, and a stable supply of flavor components to the user can be realized.

Since the bag body and the exterior body are joined on the inner side in the axial direction than the outer end portion of the bag body in the axial direction of the exterior body, the exterior body can be deformed separately from the axial end portion of the bag body. And the bag can be deformed into a cylindrical shape.

Since the bag body and the exterior body are joined at a plurality of positions spaced in the axial direction of the exterior body, the exterior body and the bag body can be brought close to each other in the region between the joint portions in the axial direction, and the flavor component Leakage can be suppressed.

The joint portion 50 is provided between the first fold line L1 and the second fold line L2 so as to be separated from the first fold line L1 and the second fold line L2, and the bag body is separated from the fold line of the exterior body. It is joined to the exterior body at the position. The first fold and the second fold are portions that the user presses with a finger or the like at the time of deformation, and the bag body and the first fold and the second fold of the exterior body can be brought into close contact when deformed. On the other hand, the space between the first fold and the second fold of the exterior body is a portion that is deformed into an arc shape or the like when deformed, and is easily separated from the bag body during deformation. Therefore, by providing the joint part apart from the first fold line and the second fold line, the joint part can be provided at a portion where the bag body and the exterior body are easily separated at the time of deformation. The area in contact with can be increased.

(6) Other Embodiments The non-heating type flavor inhaler according to the present embodiment is configured to be provided to the user in a state where the bag body and the exterior body are integrated. Such a non-heating type flavor inhaler is not limited to this configuration. For example, the bag body and the exterior body are provided separately to the user so that the user can integrate the bag body and the exterior body at the time of use through a joint provided in at least one of the bag body and the exterior body. It may be configured.

Further, the bag body is not limited to the above-described configuration, and various configurations can be adopted. For example, the bag may be formed by folding the fold along the width direction in the axial direction without folding the fold along the axial direction in the axial direction and joining the second side along the axial direction. . According to such a bag 30, the cross-sectional shape shown in FIG. 7 is an arc shape protruding toward the opening.

It is desirable that the outer periphery of the bag body 30 and the inner periphery of the exterior body 40 have the same length. For example, if the outer periphery of the bag body 30 is too longer than the inner periphery of the exterior body 40, the bag body 30 is bent away from the exterior body 40 even if a part of the bag body 30 is in close contact with the exterior body 40. Is formed and does not adhere to the exterior body 40 all around the bag body 30. On the other hand, if the outer periphery of the bag body 30 is too short than the inner periphery of the exterior body 40, a gap is formed between the exterior body 40 and the bag body 30, and the bag body 30 is disposed along the inner surface of the exterior body 40. Not. However, by making the outer periphery of the bag body 30 and the inner periphery of the exterior body 40 the same length, the entire outer periphery of the bag body 30 and the entire inner periphery of the exterior body 40 can be brought into close contact with each other.
