As such a flavor aspirator, for example, a liquid heating type aspirator is known. The liquid heating type aspirator supplies an aerosol generated by atomizing a liquid containing a flavor such as nicotine (aerosol forming material) to the user's mouth, or atomizes a liquid not containing a flavor such as nicotine. The generated aerosol is passed through a flavor source (for example, a tobacco source) and then supplied to the user's mouth.
　液体加熱式の吸引器には、エアロゾルを生成するための液体を収容するカートリッジと、この液体を霧化する霧化部とを備えるものがある。このようなカートリッジとして、液体を補充することで繰り返し使用可能なものが知られている。また、カートリッジに液体を補充する機構として、中空構造のニードルからカートリッジ内の空気を逃がしながら、同時に液体を充填するものが知られている（例えば、特許文献１参照）。 Some liquid-heated aspirators are equipped with a cartridge that houses a liquid for generating aerosols and an atomizer that atomizes this liquid. As such a cartridge, a cartridge that can be used repeatedly by replenishing a liquid is known. Further, as a mechanism for replenishing the cartridge with liquid, a mechanism is known in which air in the cartridge is released from a needle having a hollow structure and the liquid is filled at the same time (see, for example, Patent Document 1).

　以下、本発明によるカートリッジおよびこれを備えた香味吸引器について図面を用いて説明するが、各図において同一、または相当する部分については、同一符号を付して説明する。 Hereinafter, the cartridge according to the present invention and the flavor aspirator provided with the cartridge will be described with reference to the drawings, but the same or corresponding parts in each drawing will be described with the same reference numerals.
　第１実施形態：
　図１は、本発明の第１実施形態に係る香味吸引器を示す斜視図である。図１において、香味吸引器１００は、互いに着脱可能に構成されたマウスピース１１と、霧化ユニット１２と、バッテリ１３とを備えている。霧化ユニット１２は、グリセリンやプロピレングリコール等のエアロゾル形成材料を収容するカートリッジ２０（図２参照）と、エアロゾル形成材料を霧化する霧化部（図示せず）とを有している。 First Embodiment:
FIG. 1 is a perspective view showing a flavor aspirator according to the first embodiment of the present invention. In FIG. 1, the flavor aspirator 100 includes a mouthpiece 11 configured to be detachable from each other, an atomization unit 12, and a battery 13. The atomization unit 12 has a cartridge 20 (see FIG. 2) for accommodating an aerosol-forming material such as glycerin and propylene glycol, and an atomizing unit (not shown) for atomizing the aerosol-forming material.
　霧化部は、カートリッジ２０に収容されたエアロゾル形成材料を霧化して、マウスピース１１に向けてエアロゾルを供給する。マウスピース１１は、霧化部で生成されたエアロゾルを使用者の口に導く。バッテリ１３は、霧化部に電力を供給する。ここで、カートリッジ２０は、エアロゾル形成材料を補充することで繰り返し使用することができるものである。また、エアロゾル形成材料には、例えばニコチン等が含まれる場合もある。 The atomizing unit atomizes the aerosol forming material contained in the cartridge 20 and supplies the aerosol toward the mouthpiece 11. The mouthpiece 11 guides the aerosol produced in the atomization section to the user's mouth. The battery 13 supplies electric power to the atomizing section. Here, the cartridge 20 can be used repeatedly by replenishing the aerosol forming material. Further, the aerosol forming material may contain, for example, nicotine and the like.
　図２は、本発明の第１実施形態に係るカートリッジを示す断面図である。図２において、カートリッジ２０は、ハウジング３０と、シール部材（可動部材）４０と、凹部（連通機構）５０と、ウィック６０とを備えている。 FIG. 2 is a cross-sectional view showing a cartridge according to the first embodiment of the present invention. In FIG. 2, the cartridge 20 includes a housing 30, a seal member (movable member) 40, a recess (communication mechanism) 50, and a wick 60.
　ハウジング３０は、一端が開放された有底円筒状であり、開口３１、内壁３２および底面３３を有している。ハウジング３０は、樹脂、ガラス、金属等で形成されている。シール部材４０は、円盤形状であり、ハウジング３０の内壁３２に沿って摺動可能に設けられている。シール部材４０は、ゴム等の弾性部材で形成されている。なお、ハウジングは、円筒状に限定されず、四角形等の多角形筒状であってもよい。このとき、シール部材は、ハウジングの内壁形状に即した形状となる。 The housing 30 has a bottomed cylindrical shape with one end open, and has an opening 31, an inner wall 32, and a bottom surface 33. The housing 30 is made of resin, glass, metal or the like. The seal member 40 has a disk shape and is slidably provided along the inner wall 32 of the housing 30. The seal member 40 is made of an elastic member such as rubber. The housing is not limited to a cylindrical shape, and may be a polygonal tubular shape such as a quadrangle. At this time, the seal member has a shape that matches the shape of the inner wall of the housing.
　ここで、ハウジング３０の内壁３２および底面３３とシール部材４０とにより、閉鎖空間７０が画定される。閉鎖空間７０は、シール部材４０がハウジング３０の開口３１に向けて移動することで減圧される。 Here, the closed space 70 is defined by the inner wall 32 and the bottom surface 33 of the housing 30, and the sealing member 40. The closed space 70 is decompressed by the sealing member 40 moving toward the opening 31 of the housing 30.
　凹部５０は、ハウジング３０の開口端において、ハウジング３０の内壁３２の一部として設けられている。凹部５０の内周面の直径は、内壁３２の内周面の直径およびシール部材４０の最大直径よりも大きく形成されている。凹部５０は、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間を形成することで、閉鎖空間７０をカートリッジ２０の外部空間と連通させる。 The recess 50 is provided as a part of the inner wall 32 of the housing 30 at the open end of the housing 30. The diameter of the inner peripheral surface of the recess 50 is formed to be larger than the diameter of the inner peripheral surface of the inner wall 32 and the maximum diameter of the sealing member 40. The recess 50 communicates the closed space 70 with the external space of the cartridge 20 by forming a gap between the inner wall 32 of the housing 30 and the outer peripheral surface of the sealing member 40.
　ウィック６０は、ハウジング３０の開口３１を覆うように配置されている。ウィック６０は、カートリッジ２０に収容されて霧化部に供給されるエアロゾル形成材料を保持する部材である。ウィック６０は、ガラス繊維、多孔質セラミック等で形成されている。なお、後述するエアロゾル形成材料の補充時に、ウィック６０がカートリッジ２０内に入り込まないように、開口３１を覆うようにメッシュ状の部材を配置した上で、ウィック６０を設けてもよい。また、ウィック６０がカートリッジ２０内に入り込まないように、ウィック６０の被覆面積を、ハウジング３０の開口面積よりも大きくしてもよい。 The wick 60 is arranged so as to cover the opening 31 of the housing 30. The wick 60 is a member that holds the aerosol-forming material contained in the cartridge 20 and supplied to the atomizing portion. The wick 60 is made of glass fiber, porous ceramic, or the like. The wick 60 may be provided after arranging a mesh-like member so as to cover the opening 31 so that the wick 60 does not enter the cartridge 20 when the aerosol forming material described later is replenished. Further, the covering area of the wick 60 may be larger than the opening area of the housing 30 so that the wick 60 does not enter the cartridge 20.
　続いて、図３を参照しながら、使用者がカートリッジ２０にエアロゾル形成材料を補充する手順について説明する。図３は、本発明の第１実施形態に係るカートリッジを用いたエアロゾル形成材料の補充手順を示す説明図である。なお、カートリッジ２０の使用時において、シール部材４０は、開口３１近傍に位置している。 Subsequently, the procedure for the user to replenish the aerosol forming material to the cartridge 20 will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a procedure for replenishing an aerosol-forming material using a cartridge according to the first embodiment of the present invention. When the cartridge 20 is used, the seal member 40 is located near the opening 31.
　使用者は、カートリッジ２０に収容されたエアロゾル形成材料を消費すると、まず、シール部材４０をハウジング３０の底面３３に向けて移動させる（状態Ａ）。このとき、シール部材４０は、ハウジング３０の底面３３に設けられた係合部（図示せず）を介して外部から挿入される棒状部材４１によって移動される。ここで、上述した閉鎖空間７０を減圧するために、係合部における十分な気密性が確保されている。これにより、簡易な構成でシール部材４０を移動させることができる。なお、棒状部材４１は、取り外し可能であってもよいし、折りたたみ可能であってもよいし、伸縮可能であってもよい。 When the user consumes the aerosol forming material contained in the cartridge 20, the user first moves the sealing member 40 toward the bottom surface 33 of the housing 30 (state A). At this time, the seal member 40 is moved by a rod-shaped member 41 inserted from the outside via an engaging portion (not shown) provided on the bottom surface 33 of the housing 30. Here, in order to reduce the pressure in the closed space 70 described above, sufficient airtightness is ensured in the engaging portion. As a result, the seal member 40 can be moved with a simple configuration. The rod-shaped member 41 may be removable, foldable, or stretchable.
　また、シール部材４０をハウジング３０の底面３３に向けて移動させる際、閉鎖空間７０が加圧されることを避けるために、シール部材４０は、底面３３に向けて移動する場合に、ハウジング３０の内壁３２との間に隙間を形成するように構成されている。具体的には、シール部材４０は、図３に示した断面において、底面３３に向けて突出した曲面形状を有していてもよい。このようなシール部材４０は、底面３３に向けて移動する場合に、容易に変形して閉鎖空間７０の空気や液体を逃がすことができる。なお、閉鎖空間７０から外部空間に向かう流れのみを許容する逆止弁を設けた場合であっても、閉鎖空間７０の空気や液体を逃がすことができる。逆止弁は、シール部材４０や底面３３、係合部などに設けることができる。 Further, in order to prevent the closed space 70 from being pressurized when the seal member 40 is moved toward the bottom surface 33 of the housing 30, the seal member 40 is moved toward the bottom surface 33 of the housing 30. It is configured to form a gap with the inner wall 32. Specifically, the seal member 40 may have a curved surface shape that protrudes toward the bottom surface 33 in the cross section shown in FIG. When such a sealing member 40 moves toward the bottom surface 33, it can be easily deformed to allow air or liquid in the closed space 70 to escape. Even when a check valve that allows only the flow from the closed space 70 to the external space is provided, the air or liquid in the closed space 70 can escape. The check valve can be provided on the seal member 40, the bottom surface 33, the engaging portion, and the like.
　続いて、使用者は、ハウジング３０の開口３１を液ボトル８０と当接させ、シール部材４０をハウジング３０の開口３１に向けて移動させる（状態Ｂ）。液ボトル８０は、エアロゾル形成材料を収容するボトル本体８１と、ハウジング３０の開口３１と当接する接触部８２と、ボトル本体８１のエアロゾル形成材料を接触部８２に供給する液供給管８３とを有している。接触部８２は、スポンジ状の液保持部であってもよい。シール部材４０がハウジング３０の開口３１に向けて移動することで、閉鎖空間７０が減圧される。これにより、カートリッジ２０にエアロゾル形成材料を補充する際に、カートリッジ２０内に減圧された空間をあらかじめ形成することができる。 Subsequently, the user brings the opening 31 of the housing 30 into contact with the liquid bottle 80 and moves the sealing member 40 toward the opening 31 of the housing 30 (state B). The liquid bottle 80 has a bottle body 81 for accommodating an aerosol forming material, a contact portion 82 in contact with the opening 31 of the housing 30, and a liquid supply pipe 83 for supplying the aerosol forming material of the bottle body 81 to the contact portion 82. doing. The contact portion 82 may be a sponge-like liquid holding portion. As the sealing member 40 moves toward the opening 31 of the housing 30, the closed space 70 is depressurized. Thereby, when the aerosol forming material is replenished to the cartridge 20, a decompressed space can be formed in advance in the cartridge 20.
　なお、シール部材４０と棒状部材４１とを組み合わせて、シール部材４０が底面３３に向けて移動する場合に閉鎖空間７０の空気や液体を逃がすとともに、シール部材４０が開口３１に向けて移動する場合に閉鎖空間７０を減圧してもよい。以下、図４を参照しながら、具体的な構成について説明する。図４において、シール部材４０は、棒状部材４１が挿入される穴４０ａと、シール部材４０の下面で、穴４０ａの周囲に間隔をあけて設けられた突起４０ｂとを有している。また、棒状部材４１は、シール部材４０を挟むように設けられた上側フランジ４１ａおよび下側フランジ４１ｂを有している。 When the seal member 40 and the rod-shaped member 41 are combined to allow air or liquid in the closed space 70 to escape when the seal member 40 moves toward the bottom surface 33, and the seal member 40 moves toward the opening 31. The closed space 70 may be depressurized. Hereinafter, a specific configuration will be described with reference to FIG. In FIG. 4, the seal member 40 has a hole 40a into which the rod-shaped member 41 is inserted, and a protrusion 40b provided at a space around the hole 40a on the lower surface of the seal member 40. Further, the rod-shaped member 41 has an upper flange 41a and a lower flange 41b provided so as to sandwich the seal member 40.
　図４に示したシール部材４０と棒状部材４１との組み合わせにおいて、シール部材４０が底面３３（図中上方）に向けて移動する場合、突起４０ｂによりシール部材４０と下側フランジ４１ｂとの間に隙間が形成され、閉鎖空間７０の空気や液体を逃がすことができる。一方、シール部材４０が開口３１（図中下方）に向けて移動する場合、シール部材４０と上側フランジ４１ａとの間の隙間が塞がれ、閉鎖空間７０が減圧される。なお、突起は、シール部材４０の下面ではなく、下側フランジ４１ｂの上側に設けられてもよい。 In the combination of the seal member 40 and the rod-shaped member 41 shown in FIG. 4, when the seal member 40 moves toward the bottom surface 33 (upper part in the figure), the protrusion 40b betweens the seal member 40 and the lower flange 41b. A gap is formed, and air or liquid in the closed space 70 can escape. On the other hand, when the seal member 40 moves toward the opening 31 (lower part in the drawing), the gap between the seal member 40 and the upper flange 41a is closed, and the closed space 70 is depressurized. The protrusion may be provided on the upper side of the lower flange 41b instead of the lower surface of the seal member 40.
　また、図４に示したシール部材４０と棒状部材４１との組み合わせに代えて、図５に示されるように、下側フランジ４１ｂに貫通孔４１ｃを設けてもよいし、図６に示されるように、シール部材４０の穴４０ａに内歯歯車状の溝４０ｃを設けるとともに、上側フランジ４１ａの外径を溝４０ｃの深さよりも大きくし、下側フランジ４１ｂの外径を溝４０ｃの深さよりも小さくしてもよい。これらの場合も、シール部材４０が底面３３に向けて移動する場合に閉鎖空間７０の空気や液体を逃がすとともに、シール部材４０が開口３１に向けて移動する場合に閉鎖空間７０を減圧することができる。 Further, instead of the combination of the seal member 40 and the rod-shaped member 41 shown in FIG. 4, a through hole 41c may be provided in the lower flange 41b as shown in FIG. 5, as shown in FIG. In addition, an internal gear-shaped groove 40c is provided in the hole 40a of the seal member 40, the outer diameter of the upper flange 41a is made larger than the depth of the groove 40c, and the outer diameter of the lower flange 41b is made larger than the depth of the groove 40c. It may be made smaller. Also in these cases, when the seal member 40 moves toward the bottom surface 33, air or liquid in the closed space 70 can escape, and when the seal member 40 moves toward the opening 31, the closed space 70 can be depressurized. can.
　図３に戻って、使用者がシール部材４０をハウジング３０の開口３１に向けて移動させた結果、シール部材４０が凹部５０に到達すると、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成され、閉鎖空間７０がカートリッジ２０の外部空間と連通される（状態Ｃ）。 Returning to FIG. 3, as a result of the user moving the seal member 40 toward the opening 31 of the housing 30, when the seal member 40 reaches the recess 50, the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40 come into contact with each other. A gap is formed between them, and the closed space 70 is communicated with the external space of the cartridge 20 (state C).
　減圧された閉鎖空間７０がカートリッジ２０の外部空間と連通されると、ボトル本体８１に収容されたエアロゾル形成材料が液供給管８３および接触部８２を通って、ハウジング３０の内壁３２とシール部材４０の外周面との隙間からハウジング３０内に導入される（状態Ｄ）。これにより、カートリッジ２０にエアロゾル形成材料を補充することができる。 When the decompressed closed space 70 is communicated with the external space of the cartridge 20, the aerosol-forming material contained in the bottle body 81 passes through the liquid supply pipe 83 and the contact portion 82, and the inner wall 32 of the housing 30 and the sealing member 40. It is introduced into the housing 30 through the gap between the outer peripheral surface and the outer peripheral surface (state D). This makes it possible to replenish the cartridge 20 with the aerosol forming material.
　なお、図７に示されるように、凹部５０の開口３１側でシール部材４０がハウジング３０の内壁３２に沿って摺動可能である場合には、凹部５０に到達したシール部材４０をさらに開口３１に向けて押し込むことにより、閉鎖空間７０を密閉することができる。この場合には、輸送時や保管時におけるカートリッジ２０からの液漏れを防止することができる。 As shown in FIG. 7, when the seal member 40 is slidable along the inner wall 32 of the housing 30 on the opening 31 side of the recess 50, the seal member 40 that has reached the recess 50 is further opened 31. The closed space 70 can be sealed by pushing it toward. In this case, it is possible to prevent liquid leakage from the cartridge 20 during transportation and storage.
　以上のように、第１実施形態によれば、カートリッジは、一端に開口を有する有底筒状のハウジングと、ハウジングの内壁に沿って摺動可能に設けられた可動部材と、ハウジングおよび可動部材の少なくとも一方に設けられ、ハウジングの内壁および底面と可動部材とで画定される閉鎖空間を外部空間と連通させる連通機構と、を備え、閉鎖空間は、可動部材が開口に向けて移動することで減圧される。そのため、カートリッジに液体を補充する際に、カートリッジ内に減圧された空間をあらかじめ形成することができる。 As described above, according to the first embodiment, the cartridge includes a bottomed cylindrical housing having an opening at one end, a movable member slidably provided along the inner wall of the housing, and the housing and the movable member. The closed space is provided with a communication mechanism that communicates the closed space defined by the inner wall and bottom surface of the housing with the external space, and the closed space is provided by the movable member moving toward the opening. The pressure is reduced. Therefore, when the cartridge is refilled with liquid, a decompressed space can be formed in advance in the cartridge.
　なお、上記第１実施形態において、連通機構の構成は、上述したものに限定されない。連通機構は、ハウジング３０の開口端の近傍に、シール部材４０と当接するように設けられ、シール部材４０を変形または変位させることで、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間を形成する当接部材であってもよい。 In the first embodiment, the configuration of the communication mechanism is not limited to that described above. The communication mechanism is provided in the vicinity of the open end of the housing 30 so as to be in contact with the seal member 40, and by deforming or displacementing the seal member 40, the communication mechanism is between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40. It may be a contact member that forms a gap between the two.
　具体的には、当接部材は、図８に示すような、ハウジング３０の内壁３２に設けられた爪状部材５１であってもよい。図８では、間隔をおいて２箇所に爪状部材５１が設けられている。シール部材４０が可撓性部材で形成されている場合に、シール部材４０がハウジング３０の開口３１に向けて移動すると、爪状部材５１がシール部材４０に当接してシール部材４０を変形させ、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。なお、爪状部材５１は、少なくとも１箇所に設けられていればよい。 Specifically, the contact member may be a claw-shaped member 51 provided on the inner wall 32 of the housing 30 as shown in FIG. In FIG. 8, claw-shaped members 51 are provided at two locations at intervals. When the seal member 40 is made of a flexible member and the seal member 40 moves toward the opening 31 of the housing 30, the claw-shaped member 51 abuts on the seal member 40 to deform the seal member 40. A gap is formed between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40. The claw-shaped member 51 may be provided at at least one place.
　当接部材は、図９に示すような、ハウジング３０の内壁３２に設けられた爪状部材５２であってもよい。図９では、１箇所に爪状部材５２が設けられている。シール部材４０が剛性部材で形成されている場合に、シール部材４０がハウジング３０の開口３１に向けて移動すると、爪状部材５２がシール部材４０に当接してシール部材４０が傾くようにシール部材４０を変位させ、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。なお、爪状部材５２は、シール部材４０が変位する位置であれば、２箇所以上に設けられてもよい。 The contact member may be a claw-shaped member 52 provided on the inner wall 32 of the housing 30 as shown in FIG. In FIG. 9, a claw-shaped member 52 is provided at one location. When the seal member 40 is formed of a rigid member, when the seal member 40 moves toward the opening 31 of the housing 30, the claw-shaped member 52 abuts on the seal member 40 and the seal member 40 is tilted. The 40 is displaced to form a gap between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40. The claw-shaped member 52 may be provided at two or more locations as long as the seal member 40 is displaced.
　連通機構は、図１０に示すような、シール部材４０を構成する２枚のプレート４２、４３であってもよい。２枚のプレート４２、４３には、それぞれ孔４４、４５が形成され、２枚のプレート４２、４３の孔４４、４５が位置合わせされることで、閉鎖空間７０が外部空間と連通される。ここで、プレートの位置合わせは、ハウジング３０の底面３３に挿入された棒状部材４１を回転させることによって行われる。 The communication mechanism may be two plates 42, 43 constituting the seal member 40, as shown in FIG. Holes 44 and 45 are formed in the two plates 42 and 43, respectively, and the holes 44 and 45 of the two plates 42 and 43 are aligned so that the closed space 70 communicates with the external space. Here, the alignment of the plate is performed by rotating the rod-shaped member 41 inserted into the bottom surface 33 of the housing 30.
　連通機構は、図１１に示すような、ハウジング３０に設けられ、外部空間から閉鎖空間７０に向かう流れのみを許容する逆止弁５３であってもよい。閉鎖空間７０が減圧された状態で、逆止弁５３を介してエアロゾル形成材料を供給することにより、カートリッジ２０にエアロゾル形成材料を補充することができる。閉鎖空間７０が十分に減圧された状態でエアロゾル形成材料を供給することができるように、逆止弁５３は、ハウジング３０の開口３１の近傍に設けられることが望ましい。 The communication mechanism may be a check valve 53 provided in the housing 30 as shown in FIG. 11 and allowing only the flow from the external space to the closed space 70. The aerosol forming material can be replenished to the cartridge 20 by supplying the aerosol forming material through the check valve 53 in a state where the closed space 70 is depressurized. It is desirable that the check valve 53 be provided in the vicinity of the opening 31 of the housing 30 so that the aerosol forming material can be supplied while the closed space 70 is sufficiently depressurized.
　連通機構は、液体に触れることで縮むように構成されたシール部材４０であってもよい。シール部材４０が縮むことにより、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。 The communication mechanism may be a sealing member 40 configured to shrink when in contact with a liquid. As the seal member 40 shrinks, a gap is formed between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40.
　連通機構は、ハウジング３０の底面３３に挿入された棒状部材４１を回転させることによって、シール部材４０の直径を変化させるような機構であってもよい。シール部材４０の直径を小さくすることで、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。 The communication mechanism may be a mechanism that changes the diameter of the seal member 40 by rotating the rod-shaped member 41 inserted into the bottom surface 33 of the housing 30. By reducing the diameter of the seal member 40, a gap is formed between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40.
　連通機構は、熱や電気によってシール部材４０を変形させるような機構であってもよい。熱によってシール部材４０を変形させるような機構としては、形状記憶合金やバイメタルを用いたものが挙げられる。また、電気によってシール部材４０を変形させるような機構としては、ピエゾアクチュエータを用いたものが挙げられる。熱や電気によってシール部材４０を変形させることで、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。 The communication mechanism may be a mechanism that deforms the seal member 40 by heat or electricity. Examples of the mechanism that deforms the seal member 40 by heat include those using a shape memory alloy or bimetal. Further, as a mechanism for deforming the seal member 40 by electricity, a mechanism using a piezo actuator can be mentioned. By deforming the seal member 40 by heat or electricity, a gap is formed between the inner wall 32 of the housing 30 and the outer peripheral surface of the seal member 40.
　また、上記第１実施形態では、シール部材４０が底面３３に向けて突出した曲面形状を有していることにより、シール部材４０が底面３３に向けて移動する場合に、ハウジング３０の内壁３２との間に隙間を形成する例を挙げたが、これに限定されない。具体的には、シール部材４０が底面３３に向けて移動する場合に、ハウジング３０の内壁３２との間に隙間を形成するために、内壁３２の内周面の直径が、開口３１から底面３３に向けて、テーパ状に拡大してもよい。なお、テーパ状の領域は、開口３１から底面３３までの全長に限定されず、例えば開口３１からハウジング３０の長さ方向中間位置あたりまでであってもよい。 Further, in the first embodiment, since the seal member 40 has a curved surface shape protruding toward the bottom surface 33, when the seal member 40 moves toward the bottom surface 33, the inner wall 32 of the housing 30 is formed. An example of forming a gap between the two is given, but the present invention is not limited to this. Specifically, when the sealing member 40 moves toward the bottom surface 33, the diameter of the inner peripheral surface of the inner wall 32 is changed from the opening 31 to the bottom surface 33 in order to form a gap between the sealing member 40 and the inner wall 32 of the housing 30. It may be expanded in a tapered shape toward. The tapered region is not limited to the total length from the opening 31 to the bottom surface 33, and may be, for example, from the opening 31 to the intermediate position in the length direction of the housing 30.
　このとき、ハウジング３０が開口３１に向けてしぼんでいるので、シール部材４０とハウジング３０の内壁３２との密着性を向上させることができる。また、シール部材４０をエラストマ等の低反発素材で構成することにより、シール部材４０が底面３３に向けて移動する場合には、シール部材４０の直径がゆっくり拡大するので、ハウジング３０の内壁３２とシール部材４０の外周面との間に隙間が形成される。また、シール部材４０の直径が戻った後、シール部材４０が開口３１に向けて移動する場合には、シール部材４０とハウジング３０の内壁３２との密着性を向上させることができる。 At this time, since the housing 30 is deflated toward the opening 31, the adhesion between the sealing member 40 and the inner wall 32 of the housing 30 can be improved. Further, by forming the seal member 40 with a low-resilience material such as an elastomer, when the seal member 40 moves toward the bottom surface 33, the diameter of the seal member 40 slowly expands, so that the inner wall 32 of the housing 30 and the seal member 40 are formed. A gap is formed between the seal member 40 and the outer peripheral surface. Further, when the seal member 40 moves toward the opening 31 after the diameter of the seal member 40 has returned, the adhesion between the seal member 40 and the inner wall 32 of the housing 30 can be improved.
　また、上記第１実施形態では、シール部材４０が、ハウジング３０の底面３３に挿入された棒状部材４１によって移動される例を挙げたが、これに限定されない。具体的には、シール部材４０を移動させる棒状部材は、液ボトル８０側に設けられてもよい。また、シール部材４０は、ねじによって移動されてもよい。また、シール部材４０がボールねじによって液ボトル８０に接続され、螺合によってシール部材４０が移動されてもよい。 Further, in the first embodiment, the example in which the seal member 40 is moved by the rod-shaped member 41 inserted into the bottom surface 33 of the housing 30 is given, but the present invention is not limited to this. Specifically, the rod-shaped member for moving the seal member 40 may be provided on the liquid bottle 80 side. Further, the seal member 40 may be moved by a screw. Further, the seal member 40 may be connected to the liquid bottle 80 by a ball screw, and the seal member 40 may be moved by screwing.
　さらに、シール部材４０は、ハウジング３０の長手方向に沿って形成されたスリットによって一部が外部空間に露出するように構成され、スリットから露出された部分により移動されてもよい。また、シール部材４０を磁性体で形成し、永久磁石や電磁石によって発生する磁力を用いて移動されてもよい。 Further, the seal member 40 is configured so that a part of the seal member 40 is exposed to the external space by a slit formed along the longitudinal direction of the housing 30, and may be moved by the portion exposed from the slit. Further, the seal member 40 may be formed of a magnetic material and may be moved by using a magnetic force generated by a permanent magnet or an electromagnet.
　なお、シール部材４０の移動をサポートするために、ハウジング３０の底面３３とシール部材４０との間に、シール部材４０を開口３１に向けて付勢するバネやゴムを設けてもよい。 In order to support the movement of the seal member 40, a spring or rubber may be provided between the bottom surface 33 of the housing 30 and the seal member 40 to urge the seal member 40 toward the opening 31.
　第２実施形態：
　次に、本発明の第２実施形態に係るカートリッジについて説明する。図１２は、本発明の第２実施形態に係るカートリッジ、およびこれを用いたエアロゾル形成材料の補充手順を示す説明図である。 Second embodiment:
Next, the cartridge according to the second embodiment of the present invention will be described. FIG. 12 is an explanatory diagram showing a cartridge according to a second embodiment of the present invention and a procedure for replenishing an aerosol forming material using the cartridge.
　図１２において、カートリッジ２０Ａは、ハウジング３０Ａと、シール部材４０Ａと、ウィック６０Ａとを備えている。ハウジング３０Ａは、円筒状であり、第１開口３１Ａ、内壁３２Ａおよび第２開口３３Ａを有している。ハウジング３０Ａは、樹脂、ガラス、金属等で形成されている。シール部材４０Ａは、円盤形状であり、ハウジング３０Ａの内壁３２Ａに沿って摺動可能に設けられている。シール部材４０Ａは、ゴム等の弾性部材で形成されている。 In FIG. 12, the cartridge 20A includes a housing 30A, a sealing member 40A, and a wick 60A. The housing 30A is cylindrical and has a first opening 31A, an inner wall 32A and a second opening 33A. The housing 30A is made of resin, glass, metal or the like. The seal member 40A has a disk shape and is slidably provided along the inner wall 32A of the housing 30A. The seal member 40A is made of an elastic member such as rubber.
　ウィック６０Ａは、ハウジング３０Ａの第１開口３１Ａを覆うように配置されている。ウィック６０Ａは、カートリッジ２０Ａに収容されて霧化部に供給されるエアロゾル形成材料を保持する部材である。ウィック６０Ａは、ガラス繊維、多孔質セラミック等で形成されている。なお、第１実施形態と同様に、第１開口３１Ａを覆うようにメッシュ状の部材を配置した上で、ウィック６０Ａを設けてもよいし、ウィック６０Ａの被覆面積を、ハウジング３０Ａの開口面積よりも大きくしてもよい。 The wick 60A is arranged so as to cover the first opening 31A of the housing 30A. The wick 60A is a member that holds the aerosol-forming material contained in the cartridge 20A and supplied to the atomizing portion. The wick 60A is made of glass fiber, porous ceramic, or the like. As in the first embodiment, the wick 60A may be provided after arranging the mesh-shaped member so as to cover the first opening 31A, or the covering area of the wick 60A may be set from the opening area of the housing 30A. May also be increased.
　続いて、図１２を参照しながら、使用者がカートリッジ２０Ａにエアロゾル形成材料を補充する手順について説明する。なお、カートリッジ２０Ａの使用時において、シール部材４０Ａは、第２開口３３Ａ近傍に位置している。 Subsequently, the procedure for the user to replenish the aerosol forming material to the cartridge 20A will be described with reference to FIG. 12. When the cartridge 20A is used, the seal member 40A is located in the vicinity of the second opening 33A.
　使用者は、カートリッジ２０Ａに収容されたエアロゾル形成材料を消費すると（状態Ａ）、まず、ハウジング３０Ａの第１開口３１Ａを液ボトル８０Ａと当接させ、シール部材４０Ａをハウジング３０Ａの第１開口３１Ａに向けて移動させる（状態Ｂ）。液ボトル８０Ａの構成は、第１実施形態で示した液ボトル８０と同様なので、説明を省略する。 When the user consumes the aerosol-forming material contained in the cartridge 20A (state A), first, the first opening 31A of the housing 30A is brought into contact with the liquid bottle 80A, and the sealing member 40A is brought into contact with the first opening 31A of the housing 30A. Move toward (state B). Since the configuration of the liquid bottle 80A is the same as that of the liquid bottle 80 shown in the first embodiment, the description thereof will be omitted.
　このとき、シール部材４０Ａは、ハウジング３０Ａの第２開口３３Ａに、取り外し可能に設けられたアタッチメント４１Ａによって移動される。なお、図１２では、棒状の部材による直線運動によってシール部材４０Ａが移動される例を示したが、これに限定されず、スクリュー等の回転運動がシール部材４０Ａの直線運動に変換されてもよい。また、シール部材４０Ａは、液ボトル８０Ａに設けられた動力部によって移動されてもよい。 At this time, the seal member 40A is moved to the second opening 33A of the housing 30A by a removable attachment 41A. Although FIG. 12 shows an example in which the seal member 40A is moved by the linear motion of the rod-shaped member, the present invention is not limited to this, and the rotational motion of the screw or the like may be converted into the linear motion of the seal member 40A. .. Further, the seal member 40A may be moved by a power unit provided in the liquid bottle 80A.
　その後、使用者は、シール部材４０Ａが第１開口３１Ａに到達すると、シール部材４０Ａの移動方向を反転させ、シール部材４０Ａをハウジング３０Ａの第２開口３３Ａに向けて移動させる（状態Ｃ）。 After that, when the seal member 40A reaches the first opening 31A, the user reverses the moving direction of the seal member 40A and moves the seal member 40A toward the second opening 33A of the housing 30A (state C).
　シール部材４０Ａがハウジング３０Ａの第２開口３３Ａに向けて移動することで、ハウジング３０Ａの内壁３２Ａとシール部材４０Ａとウィック６０Ａとの間に減圧された空間が形成される。その結果、ボトル本体８１Ａに収容されたエアロゾル形成材料が液供給管８３Ａおよび接触部８２Ａを通って、ハウジング３０Ａ内に導入される（状態Ｄ）。これにより、カートリッジ２０Ａにエアロゾル形成材料を補充することができる。 By moving the seal member 40A toward the second opening 33A of the housing 30A, a decompressed space is formed between the inner wall 32A of the housing 30A, the seal member 40A, and the wick 60A. As a result, the aerosol-forming material contained in the bottle body 81A is introduced into the housing 30A through the liquid supply pipe 83A and the contact portion 82A (state D). Thereby, the aerosol forming material can be replenished to the cartridge 20A.
　なお、ウィック６０Ａの損傷を防止するために、ウィック６０Ａとは別の経路を介してカートリッジ２０Ａにエアロゾル形成材料を補充してもよい。例えば、ハウジング３０Ａの第１開口３１Ａを液ボトル８０Ａと当接させる際に、第１開口３１Ａと液ボトル８０Ａとの係合部等を介してウィック６０Ａを密閉することで、ウィック６０Ａを通さずエアロゾル形成材料を補充してもよい。 In addition, in order to prevent damage to the wick 60A, the aerosol forming material may be replenished to the cartridge 20A via a route different from that of the wick 60A. For example, when the first opening 31A of the housing 30A is brought into contact with the liquid bottle 80A, the wick 60A is sealed through the engaging portion between the first opening 31A and the liquid bottle 80A so that the wick 60A does not pass through. Aerosol-forming materials may be replenished.
　以上のように、第２実施形態によれば、カートリッジ２０Ａは、円筒状のハウジング３０Ａと、ハウジング３０Ａの内壁３２Ａに沿って摺動可能に設けられたシール部材４０Ａと、ハウジング３０Ａの第１開口３１Ａを覆うように配置されたウィック６０Ａとを備えている。このカートリッジ２０Ａにおいて、シール部材４０Ａがハウジング３０Ａの第２開口３３Ａに向けて移動することで、ハウジング３０Ａの内壁３２Ａとシール部材４０Ａとウィック６０Ａとの間に減圧された空間が形成される。この空間にエアロゾル形成材料を導入することで、カートリッジ２０Ａにエアロゾル形成材料を補充することができる。 As described above, according to the second embodiment, the cartridge 20A has a cylindrical housing 30A, a seal member 40A slidably provided along the inner wall 32A of the housing 30A, and a first opening of the housing 30A. It is equipped with a wick 60A arranged so as to cover 31A. In the cartridge 20A, the sealing member 40A moves toward the second opening 33A of the housing 30A, so that a decompressed space is formed between the inner wall 32A of the housing 30A, the sealing member 40A, and the wick 60A. By introducing the aerosol-forming material into this space, the aerosol-forming material can be replenished in the cartridge 20A.
　第３実施形態：
　次に、本発明の第３実施形態に係るカートリッジについて説明する。図１３は、本発明の第３実施形態に係るカートリッジ、およびこれを用いたエアロゾル形成材料の補充手順を示す説明図である。 Third embodiment:
Next, the cartridge according to the third embodiment of the present invention will be described. FIG. 13 is an explanatory diagram showing a cartridge according to a third embodiment of the present invention and a procedure for replenishing an aerosol forming material using the cartridge.
　図１３において、カートリッジ２０Ｂは、ハウジング３０Ｂと、弾性容器９０Ｂと、ウィック６０Ｂとを備えている。ハウジング３０Ｂは、一端が開放された有底円筒状であり、開口３１Ｂ、内壁３２Ｂおよび底面３３Ｂを有している。ハウジング３０Ｂは、樹脂、ガラス、金属等で形成されている。 In FIG. 13, the cartridge 20B includes a housing 30B, an elastic container 90B, and a wick 60B. The housing 30B has a bottomed cylindrical shape with one end open, and has an opening 31B, an inner wall 32B, and a bottom surface 33B. The housing 30B is made of resin, glass, metal or the like.
　弾性容器９０Ｂは、袋状であり、ハウジング３０Ｂ内に設けられてハウジング３０Ｂの開口３１Ｂと一致する開口９１Ｂを有している。弾性容器９０Ｂは、ゴム等の弾性部材で形成されている。エアロゾル形成材料は、弾性容器９０Ｂ内に収容される。ここで、弾性容器９０Ｂは、内部のエアロゾル形成材料が減少しても変形しない程度の復元力を有している。また、弾性容器９０Ｂは、全体が弾性部材である必要はなく、一部が弾性部材であってもよい。 The elastic container 90B is bag-shaped and has an opening 91B provided in the housing 30B and corresponding to the opening 31B of the housing 30B. The elastic container 90B is made of an elastic member such as rubber. The aerosol-forming material is housed in the elastic container 90B. Here, the elastic container 90B has a restoring force that does not deform even if the aerosol forming material inside is reduced. Further, the elastic container 90B does not have to be an elastic member as a whole, and a part of the elastic container 90B may be an elastic member.
　ウィック６０Ｂは、ハウジング３０Ｂの開口３１Ｂおよび弾性容器９０Ｂの開口９１Ｂを覆うように配置されている。ウィック６０Ｂは、カートリッジ２０Ｂ（弾性容器９０Ｂ）に収容されて霧化部に供給されるエアロゾル形成材料を保持する部材である。ウィック６０Ｂは、ガラス繊維、多孔質セラミック等で形成されている。なお、第１実施形態と同様に、開口３１Ｂを覆うようにメッシュ状の部材を配置した上で、ウィック６０Ｂを設けてもよいし、ウィック６０Ｂの被覆面積を、ハウジング３０Ｂの開口面積よりも大きくしてもよい。 The wick 60B is arranged so as to cover the opening 31B of the housing 30B and the opening 91B of the elastic container 90B. The wick 60B is a member that holds the aerosol-forming material contained in the cartridge 20B (elastic container 90B) and supplied to the atomizing portion. The wick 60B is made of glass fiber, porous ceramic, or the like. As in the first embodiment, the wick 60B may be provided after arranging the mesh-shaped member so as to cover the opening 31B, or the covering area of the wick 60B may be larger than the opening area of the housing 30B. You may.
　続いて、図１３を参照しながら、使用者がカートリッジ２０Ｂにエアロゾル形成材料を補充する手順について説明する。 Subsequently, with reference to FIG. 13, the procedure in which the user replenishes the aerosol forming material to the cartridge 20B will be described.
　使用者は、カートリッジ２０Ｂに収容されたエアロゾル形成材料を消費すると（状態Ａ）、まず、ハウジング３０Ｂの開口３１Ｂを液ボトル８０Ｂと当接させ、次いで弾性容器９０Ｂを圧縮して変形させる。弾性容器９０Ｂが圧縮されることで、弾性容器９０Ｂの内部に減圧された空間が形成される（状態Ｂ）。液ボトル８０Ｂの構成は、第１実施形態で示した液ボトル８０と同様なので、説明を省略する。 When the user consumes the aerosol-forming material contained in the cartridge 20B (state A), first, the opening 31B of the housing 30B is brought into contact with the liquid bottle 80B, and then the elastic container 90B is compressed and deformed. By compressing the elastic container 90B, a decompressed space is formed inside the elastic container 90B (state B). Since the configuration of the liquid bottle 80B is the same as that of the liquid bottle 80 shown in the first embodiment, the description thereof will be omitted.
　このとき、弾性容器９０Ｂは、ハウジング３０Ｂ内に設けられ、ハウジング３０Ｂ外部から操作可能な圧縮部材（図示せず）によって直接押圧される。なお、これに限定されず、ハウジング３０Ｂ内またはハウジング３０Ｂ外に設けられ、ハウジング３０Ｂ内を加圧することが可能なポンプ（図示せず）を用いて、弾性容器９０Ｂを圧縮してもよい。 At this time, the elastic container 90B is provided inside the housing 30B and is directly pressed by a compression member (not shown) that can be operated from the outside of the housing 30B. The elastic container 90B may be compressed by using a pump (not shown) provided inside the housing 30B or outside the housing 30B and capable of pressurizing the inside of the housing 30B.
　その後、使用者が弾性容器９０Ｂの圧縮を解除することで、弾性容器９０Ｂは、復元力によって元の形状に戻ろうとする（状態Ｃ）。その結果、ボトル本体８１Ｂに収容されたエアロゾル形成材料が液供給管８３Ｂおよび接触部８２Ｂを通って、ハウジング３０Ｂ（弾性容器９０Ｂ）内に導入される（状態Ｄ）。これにより、カートリッジ２０Ａにエアロゾル形成材料を補充することができる。 After that, when the user releases the compression of the elastic container 90B, the elastic container 90B tries to return to the original shape by the restoring force (state C). As a result, the aerosol-forming material contained in the bottle body 81B is introduced into the housing 30B (elastic container 90B) through the liquid supply pipe 83B and the contact portion 82B (state D). Thereby, the aerosol forming material can be replenished to the cartridge 20A.
　以上のように、第３実施形態によれば、カートリッジ２０Ｂは、一端が開放された有底円筒状のハウジング３０Ｂと、ハウジング３０Ｂ内に設けられた弾性容器９０Ｂと、ハウジング３０Ｂの開口３１Ｂおよび弾性容器９０Ｂの開口９１Ｂを覆うように配置されたウィック６０Ｂとを備えている。このカートリッジ２０Ｂにおいて、弾性容器９０Ｂが圧縮されることで、弾性容器９０Ｂの内部に減圧された空間が形成される。この空間にエアロゾル形成材料を導入することで、カートリッジ２０Ｂにエアロゾル形成材料を補充することができる。 As described above, according to the third embodiment, the cartridge 20B has a bottomed cylindrical housing 30B having an open end, an elastic container 90B provided in the housing 30B, an opening 31B of the housing 30B, and elasticity. It is provided with a wick 60B arranged so as to cover the opening 91B of the container 90B. In the cartridge 20B, the elastic container 90B is compressed to form a decompressed space inside the elastic container 90B. By introducing the aerosol-forming material into this space, the aerosol-forming material can be replenished in the cartridge 20B.
　第４実施形態：
　次に、本発明の第４実施形態に係るカートリッジについて説明する。図１４は、本発明の第４実施形態に係るカートリッジ、およびこれを用いたエアロゾル形成材料の補充手順を示す説明図である。 Fourth Embodiment:
Next, the cartridge according to the fourth embodiment of the present invention will be described. FIG. 14 is an explanatory diagram showing a cartridge according to a fourth embodiment of the present invention and a procedure for replenishing an aerosol forming material using the cartridge.
　図１４において、カートリッジ２０Ｃは、ハウジング３０Ｃと、シール部材４０Ｃと、栓体５４Ｃと、ウィック６０Ｃとを備えている。ハウジング３０Ｃは、一端が開放された有底筒状であり、開口３１Ｃ、内壁３２Ｃ、底面３３Ｃおよび仕切り部３４Ｃを有している。仕切り部３４Ｃは、ハウジング３０Ｃの軸方向に直交する方向に内壁３２Ｃから延出して設けられている。仕切り部３４Ｃには、孔が形成されており、シール部材４０Ｃと協働してハウジング３０Ｃの開口３１Ｃ側と底面３３Ｃ側とを空間的に仕切る。ハウジング３０Ｃは、樹脂、ガラス、金属等で形成されている。 In FIG. 14, the cartridge 20C includes a housing 30C, a seal member 40C, a plug 54C, and a wick 60C. The housing 30C has a bottomed cylindrical shape with one end open, and has an opening 31C, an inner wall 32C, a bottom surface 33C, and a partition portion 34C. The partition portion 34C is provided so as to extend from the inner wall 32C in a direction orthogonal to the axial direction of the housing 30C. A hole is formed in the partition portion 34C, which spatially partitions the opening 31C side and the bottom surface 33C side of the housing 30C in cooperation with the sealing member 40C. The housing 30C is made of resin, glass, metal or the like.
　シール部材４０Ｃは、円盤形状であり、仕切り部３４Ｃとウィック６０Ｃとの間で移動可能に設けられている。シール部材４０Ｃは、ゴム等の弾性部材で形成されている。栓体５４Ｃは、ハウジング３０Ｃの底面３３Ｃに設けられ、穿孔されることでハウジング３０Ｃの内部と外部とを空間的に連通する。栓体５４Ｃは、ゴム等の弾性部材で形成されている。 The seal member 40C has a disk shape and is provided so as to be movable between the partition portion 34C and the wick 60C. The seal member 40C is made of an elastic member such as rubber. The plug 54C is provided on the bottom surface 33C of the housing 30C, and is perforated to spatially communicate the inside and the outside of the housing 30C. The stopper 54C is made of an elastic member such as rubber.
　ウィック６０Ｃは、ハウジング３０Ｃの開口３１Ｃを覆うように配置されている。ウィック６０Ｃは、カートリッジ２０Ｃに収容されて霧化部に供給されるエアロゾル形成材料を保持する部材である。ウィック６０Ｃは、ガラス繊維、多孔質セラミック等で形成されている。 The wick 60C is arranged so as to cover the opening 31C of the housing 30C. The wick 60C is a member that holds the aerosol-forming material contained in the cartridge 20C and supplied to the atomizing portion. The wick 60C is made of glass fiber, porous ceramic, or the like.
　続いて、図１４を参照しながら、使用者がカートリッジ２０Ａにエアロゾル形成材料を補充する手順について説明する。 Subsequently, the procedure for the user to replenish the aerosol forming material to the cartridge 20A will be described with reference to FIG. 14.
　使用者は、カートリッジ２０Ｃに収容されたエアロゾル形成材料を消費すると、まず、栓体５４Ｃを介してハウジング３０Ｃ内を減圧する（状態Ａ）。このとき、ハウジング３０Ｃ内を減圧する手段としては、公知のポンプ（手動または自動）を用いることができる。また、ハウジング３０Ｃ内を減圧する際、シール部材４０Ｃは、仕切り部３４Ｃの孔を塞いでいる。これにより、ハウジング３０Ｃ内に減圧空間が形成される。 When the user consumes the aerosol-forming material contained in the cartridge 20C, the user first decompresses the inside of the housing 30C via the plug 54C (state A). At this time, a known pump (manual or automatic) can be used as a means for depressurizing the inside of the housing 30C. Further, when the pressure inside the housing 30C is reduced, the seal member 40C closes the hole of the partition portion 34C. As a result, a decompression space is formed in the housing 30C.
　なお、シール部材４０Ｃを仕切り部３４Ｃとウィック６０Ｃとの間に設けられてもよい。この場合には、ウィック６０Ｃは減圧の影響をうけずに済む。なお、シール部材４０Ｃは、ウィック６０とハウジング３０Ｃの開口３１Ｃとの間に設けられてもよい。この場合には、より大きい減圧空間を形成することができる。 The seal member 40C may be provided between the partition portion 34C and the wick 60C. In this case, the wick 60C is not affected by the reduced pressure. The seal member 40C may be provided between the wick 60 and the opening 31C of the housing 30C. In this case, a larger decompression space can be formed.
　その後、使用者は、液ボトル８０Ｃの液供給管８３Ｃにより栓体５４Ｃを穿孔する（状態Ｂ）。第４実施形態に係る液ボトル８０Ｃは、第１実施形態で示した液ボトル８０から接触部８２が省略されたものである。また、第４実施形態に係る液供給管８３Ｃは、ボトル本体８１Ｃから突出するとともに、先端が穿孔に適した形状になっている。 After that, the user drills the plug 54C with the liquid supply pipe 83C of the liquid bottle 80C (state B). In the liquid bottle 80C according to the fourth embodiment, the contact portion 82 is omitted from the liquid bottle 80 shown in the first embodiment. Further, the liquid supply pipe 83C according to the fourth embodiment protrudes from the bottle body 81C and has a tip having a shape suitable for drilling.
　栓体５４Ｃが液ボトル８０Ｃの液供給管８３Ｃにより穿孔されると、ハウジング３０Ｃ内が減圧されているので、ボトル本体８１Ｃに収容されたエアロゾル形成材料が液供給管８３Ｃを通って、ハウジング３０Ｃ内に導入される（状態Ｃ）。これにより、カートリッジ２０Ｃにエアロゾル形成材料を補充することができる。 When the stopper 54C is perforated by the liquid supply pipe 83C of the liquid bottle 80C, the pressure inside the housing 30C is reduced, so that the aerosol forming material contained in the bottle body 81C passes through the liquid supply pipe 83C and enters the housing 30C. Introduced in (state C). As a result, the aerosol forming material can be replenished in the cartridge 20C.
　カートリッジ２０Ｃにエアロゾル形成材料が補充された後は、シール部材４０Ｃが仕切り部３４Ｃから離脱し（状態Ｄ）、カートリッジ２０Ｃに収容されたエアロゾル形成材料を霧化部に供給することが可能になる。なお、公知の電子たばこ等で採用されている機構を用いて、シール部材４０Ｃを開閉制御してもよい。 After the aerosol forming material is replenished in the cartridge 20C, the sealing member 40C is separated from the partition portion 34C (state D), and the aerosol forming material contained in the cartridge 20C can be supplied to the atomizing portion. The opening / closing control of the seal member 40C may be performed by using a mechanism adopted in a known electronic cigarette or the like.
　以上のように、第４実施形態によれば、カートリッジ２０Ｃは、一端が開放された有底筒状のハウジング３０Ｃと、ハウジング３０Ｃの仕切り部３４Ｃの孔を塞ぐシール部材４０Ｃと、ハウジング３０Ｃの底面３３Ｃに設けられた栓体５４Ｃと、ハウジング３０Ｃの開口３１Ｃを覆うように配置されたウィック６０Ｃとを備えている。このカートリッジ２０Ｃにおいて、栓体５４Ｃを介してハウジング３０Ｃ内が減圧されることで、ハウジング３０Ｃ内に減圧空間が形成される。この空間にエアロゾル形成材料を導入することで、カートリッジ２０Ｃにエアロゾル形成材料を補充することができる。 As described above, according to the fourth embodiment, the cartridge 20C has a bottomed cylindrical housing 30C having one end open, a seal member 40C that closes a hole in the partition portion 34C of the housing 30C, and a bottom surface of the housing 30C. It includes a plug 54C provided on the 33C and a wick 60C arranged so as to cover the opening 31C of the housing 30C. In this cartridge 20C, the inside of the housing 30C is decompressed via the plug 54C, so that a decompression space is formed in the housing 30C. By introducing the aerosol-forming material into this space, the aerosol-forming material can be replenished in the cartridge 20C.
