Description

ポンプ付き二重容器Double container with pump
　本発明は、外容器の内側に配置された内容器の口部に、内容器の充填空間に通じるアダプタを設け、このアダプタに、キャップに固定されたポンプユニットのシリンダを収納することで、内容器に充填された内容物をポンプ操作によって噴射可能なポンプ付き二重容器に関するものである。 The present invention provides an adapter that leads to the filling space of the inner container at the mouth portion of the inner container disposed inside the outer container, and stores the cylinder of the pump unit fixed to the cap in this adapter. The present invention relates to a double container with a pump capable of injecting contents filled in a container by pump operation.
　こうしたポンプ付き二重容器としては、例えば、アダプタを中栓として、その上下端の開口部をシールすることで、内容器の交換を可能にしたものが開示されている（例えば、特許文献１参照）。 As such a double container with a pump, for example, an adapter is used as an inner plug, and an opening at the upper and lower ends thereof is sealed to enable replacement of the inner container (see, for example, Patent Document 1). ).
特開２００３－２９２０７３号公報JP 2003-292073 A
　しかしながら、こうした従来のポンプ付き二重容器は、ポンプユニットをアダプタ内に形成された収納空間に載置するにすぎないため、使用後に内容器からポンプユニットを取り外したとき、ポンプシリンダに内容物が付着することがあった。こうしたポンプシリンダに対する内容物の付着は、ポンプユニットの取り外しの際に周囲を汚す原因となる。 However, such a conventional double container with a pump merely places the pump unit in a storage space formed in the adapter, and therefore, when the pump unit is removed from the inner container after use, the contents are stored in the pump cylinder. It sometimes adhered. Such adhesion of the contents to the pump cylinder causes the surroundings to become dirty when the pump unit is removed.
　これに対し、ポンプシリンダとアダプタとの間に、パッキン等のシール材を設ければ、ポンプシリンダとアダプタとの間のシール性（密封性）が確保されるため、内容物がポンプシリンダとアダプタとの間の隙間を通してアダプタ内に形成された収納空間に流入することで、ポンプシリンダに付着することを防止することができる。 On the other hand, if a sealing material such as packing is provided between the pump cylinder and the adapter, the sealing performance (sealability) between the pump cylinder and the adapter is ensured. It can be prevented from adhering to the pump cylinder by flowing into the storage space formed in the adapter through the gap between the two.
　ところが、こうしたシール材は、その弾性変形（押し潰し）によってシール性（密封性）を確保するものであることから、使用者がキャップをしっかりと締め込まないと、使用中にポンプシリンダとアダプタとの間を通して内容器内に空気が入り込むことがある。即ち、ポンプシリンダとアダプタとの間をシール材で密封する場合、そのシール性は、使用者によるキャップの締め込み具合等によって異なり、常に一定のシール性を確保することが困難であった。 However, since such a sealing material secures sealing performance (sealing performance) by its elastic deformation (crushing), if the user does not tighten the cap firmly, Air may enter the inner container through the gap. That is, when the space between the pump cylinder and the adapter is sealed with a sealing material, the sealing performance varies depending on the tightening condition of the cap by the user, and it is difficult to always ensure a certain sealing performance.
　一方、内容物を充填する容器としては、内容物の充填空間を形成する変形可能な薄肉の内層体を有し当該内層体が外層体の口部の内側に剥離可能に連結された容器、いわゆる、デラミネーション容器（剥離容器）が挙げられる。デラミネーション容器は、内容物の取り出しに合わせて内層体が減容することで、内容物を効率的に取り出せることができる。 On the other hand, as a container for filling the contents, a container having a deformable thin inner layer body that forms a filling space for the contents, and the inner layer body is detachably connected to the inside of the mouth of the outer layer body, so-called And delamination containers (peeling containers). The delamination container can efficiently take out the contents by reducing the volume of the inner layer body as the contents are taken out.
　本発明の目的とするところは、ポンプユニットのシリンダを内容器の口部に設けたアダプタに容易に密封保持することができることで、内容器として採用されたデラミネーション容器の機能を有効に発揮させることができ、しかも、シリンダとアダプタとの間の密封性にバラつきを生じ難い、新規なポンプ付き二重容器を提供することにある。 The object of the present invention is to enable the cylinder unit of the pump unit to be easily sealed and held in the adapter provided at the mouth of the inner container, thereby effectively exerting the function of the delamination container employed as the inner container. In addition, it is an object of the present invention to provide a novel double container with a pump that can hardly cause a variation in sealing performance between a cylinder and an adapter.
　本発明のポンプ付き二重容器は、内容物の充填空間を形成する変形可能な薄肉の内層体を有し当該内層体が外層体の口部の内側に剥離可能に連結された内容器と、当該内容器を挿入可能な口部を有して当該口部を通して前記内容器が収納される外容器と、当該外容器の口部が着脱可能に取り付けられる外容器用装着部と内容器の口部が着脱可能に取り付けられる内容器用装着部とを有するキャップと、当該キャップの裏面に固定されるシリンダを有し押圧ヘッドの押し込み及び復元の繰り返しにより内容物を外界に噴射させるポンプユニットと、内容器の口部に全周に亘って嵌合保持される嵌合部を有して当該嵌合部の内周側を前記充填空間に向かって垂下させることで当該充填空間にパイプを介して通じる前記シリンダの収納空間が形成されたアダプタを備え、シリンダの本体の先端に吸入口を形作る吸入筒を設ける一方、前記アダプタの本体の先端に、前記吸入筒を全周に亘って取り囲む筒状部を設け、当該筒状部の内周面によって、前記吸入筒の外周面を全周に亘って密封状態に保持すると共に、前記アダプタの本体の先端と、シリンダの本体の先端との間に軸線方向に沿って間隔を設け、アダプタの本体とシリンダの本体との間に隙間を設けたことを特徴とするものである。なお、本発明において、「先端」とは、「アダプタ」及び「シリンダ」の末端のうち、容器の口部に取り付けたとき、当該口部から底部に向かって指向する方向の末端をいう。 The double container with a pump of the present invention has a deformable thin inner layer body that forms a filling space for the contents, and the inner layer body is releasably connected to the inside of the mouth of the outer layer body, and An outer container having a mouth part into which the inner container can be inserted and in which the inner container is housed, an outer container mounting part to which the mouth part of the outer container is detachably attached, and an inner container mouth A cap unit having an inner container mounting part to which the part is detachably attached, a pump unit having a cylinder fixed to the back surface of the cap, and injecting the contents to the outside by repeated pressing and restoring of the pressing head, and contents A fitting portion fitted and held over the entire circumference is provided at the mouth portion of the container, and the inner circumferential side of the fitting portion is suspended toward the filling space to communicate with the filling space via a pipe. A storage space for the cylinder is formed. A suction cylinder that forms a suction port at the tip of the cylinder body, and a cylindrical portion that surrounds the suction cylinder over the entire circumference at the tip of the adapter body. The inner peripheral surface of the suction cylinder holds the outer peripheral surface of the suction cylinder in a sealed state over the entire circumference, and a gap is provided along the axial direction between the distal end of the adapter body and the distal end of the cylinder body. A gap is provided between the main body of the adapter and the main body of the cylinder. In the present invention, the “tip” refers to the end of the “adapter” and the “cylinder” in the direction directed from the mouth toward the bottom when attached to the mouth of the container.
　本発明では、アダプタの本体の内周面と、シリンダの本体の外周面との間に全周に亘って隙間を設けるとともに、アダプタの本体の先端に繋がる先端側内周面とシリンダの本体の先端に繋がる先端側外周面とを全周に亘って密封状態に保持するシール面とすることができる。 In the present invention, a clearance is provided over the entire circumference between the inner peripheral surface of the adapter main body and the outer peripheral surface of the cylinder main body, and the front end side inner peripheral surface connected to the tip of the adapter main body and the cylinder main body. It can be set as the sealing surface which hold | maintains a front end side outer peripheral surface connected with a front-end | tip in a sealed state over the perimeter.
　本発明では、アダプタの本体の先端に、ポンプユニットのシリンダの本体の先端に設けた吸入筒を全周に亘って取り囲む筒状部を設け、この筒状部の内周面によって、シリンダの吸入筒の外周面を全周に亘って密封状態に保持することから、内容器に充填された内容物が、アダプタとシリンダとの間を通って流入することを阻止することができる。このため、シリンダの外周面に内容物が付着することで生じる汚れは極力抑えられる。 In the present invention, a cylindrical portion surrounding the entire circumference of the suction cylinder provided at the tip of the cylinder main body of the pump unit is provided at the tip of the adapter main body, and the cylinder suction is provided by the inner peripheral surface of the cylindrical portion. Since the outer peripheral surface of the cylinder is kept in a sealed state over the entire circumference, the contents filled in the inner container can be prevented from flowing in between the adapter and the cylinder. For this reason, the stain | pollution | contamination produced by the content adhering to the outer peripheral surface of a cylinder is suppressed as much as possible.
　また、本発明では、アダプタの本体の先端に設けた筒状部の内周面によって、シリンダの吸入筒の外周面が全周に亘って密封状態に保持されるため、使用者は、パッキン等の、弾性変形（押し潰し）を要するシール材を設けることなく、シリンダとアダプタとの間を密封することができる。このため、使用者は、シール材の押し潰しに要する大きな力を働かせることなく、シリンダの吸入筒をアダプタの筒状部の内側に嵌合させるだけの簡単な作業で、シリンダとアダプタとの間を密封することができる。 In the present invention, the outer peripheral surface of the suction cylinder of the cylinder is held in a sealed state by the inner peripheral surface of the cylindrical portion provided at the tip of the adapter main body. Thus, it is possible to seal between the cylinder and the adapter without providing a sealing material that requires elastic deformation (crushing). For this reason, the user can easily connect the cylinder and the adapter between the cylinder and the adapter by simply fitting the cylinder suction cylinder to the inside of the cylindrical portion of the adapter without exerting a large force required for crushing the sealing material. Can be sealed.
　また、本発明では、アダプタの本体の先端に設けた筒状部の内周面によって、シリンダの吸入筒の外周面が全周に亘って密封状態に保持されるため、アダプタの本体の先端とシリンダの本体の先端との間に軸線方向に沿って間隔を設け、アダプタの本体とシリンダの本体との間に隙間を形成することで、使用者は、シリンダとアダプタとの接触面積が減少する分、更に小さな力で、シリンダの吸入筒をアダプタの筒状部の内側に嵌合させることができる。 In the present invention, since the outer peripheral surface of the cylinder suction cylinder is held in a sealed state over the entire circumference by the inner peripheral surface of the cylindrical portion provided at the tip of the adapter main body, By providing a gap along the axial direction between the tip of the cylinder body and forming a gap between the adapter body and the cylinder body, the user can reduce the contact area between the cylinder and the adapter. Therefore, with a smaller force, the suction cylinder of the cylinder can be fitted inside the cylindrical portion of the adapter.
　従って、本発明によれば、ポンプユニットのシリンダを内容器の口部に設けたアダプタに容易に密封保持することができることで、内容器として採用されたデラミネーション容器の機能を有効に発揮させることでき、しかも、シリンダとアダプタとの間の密封性にバラつきを生じ難い、新規なポンプ付き二重容器を提供することができる。 Therefore, according to the present invention, the cylinder of the pump unit can be easily sealed and held in the adapter provided at the mouth of the inner container, so that the function of the delamination container adopted as the inner container can be effectively exhibited. In addition, it is possible to provide a novel double container with a pump that does not easily cause variations in the sealing performance between the cylinder and the adapter.

The inward projection 11p is hooked and locked to the outward projection 5p provided on the mouth portion 5a of the outer layer body, thereby fixing the adapter 11 to the mouth portion of the inner container 3 (the mouth portion 5a of the outer layer body).
　また、嵌合部１１ｂ1は、図４に示すように、上端１１ｂ11の内周縁から内周側（内筒壁）１１ｂ13が内容器３の充填空間Ｒ2に向かって垂下されることで、シリンダ収納空間Ｒ4を形成する。また、内周側１１ｂ13の上端部は、図４に示すように、口部４ａの内周面と接することで、外周側１１ｂ12と共に内容器３の口部（４ａ，５ａ）を挟持する。 Further, as shown in FIG. 4, the fitting portion 11 b 1 is configured such that the inner peripheral side (inner cylinder wall) 11 b 13 hangs from the inner peripheral edge of the upper end 11 b 11 toward the filling space R 2 of the inner container 3. to form a cylinder housing space R 4. Further, as shown in FIG. 4, the upper end portion of the inner peripheral side 11b 13 is in contact with the inner peripheral surface of the mouth portion 4a, thereby sandwiching the mouth portions (4a, 5a) of the inner container 3 together with the outer peripheral side 11b 12. .
　図１に示すように、アダプタ本体１１ｂの先端（以下、「アダプタ本体先端」）１１ｂ2には、充填空間Ｒ2をシリンダ収納空間Ｒ4に通じさせる筒状部１１ａが一体に設けられている。筒状部１１ａは、図３に示すように、その内側に開口部Ａ11を形作る環状壁１１ａ1が一体に設けられている。これにより、筒状部１１ａは、環状壁１１ａ1よりも先端の部分１１ａ2では、その内側で内容器３の充填空間Ｒ2に配置されるパイプ１２を嵌合保持している。 As shown in FIG. 1, a cylindrical portion 11 a that connects the filling space R 2 to the cylinder storage space R 4 is integrally provided at the tip (hereinafter, “adapter body tip”) 11 b 2 of the adapter body 11 b. . As shown in FIG. 3, the cylindrical portion 11 a is integrally provided with an annular wall 11 a 1 that forms an opening A 11 inside thereof. Thus, the cylindrical portion 11a, the portion 11a 2 of the tip of the annular wall 11a 1, are fitted and held the pipe 12 arranged in the filling space R 2 of the inner container 3 at its inner side.
　上述のように、パイプ１２をアダプタ１１で保持すれば、内溶液を使い切った後に、ポンプユニット（ディスペンサー）７を取り外そうとするときも、パイプ１２が萎んだ内容器３の内層体（内袋）４に取られて抜けてしまう事がない。なお、パイプ１２の吸入口側には、フィルタ１３が装着されているが、フィルタ１３は、省略することができる。 As described above, if the pipe 12 is held by the adapter 11, the inner layer body (inner body) of the inner container 3 in which the pipe 12 is deflated even when the pump unit (dispenser) 7 is removed after the inner solution is used up. Bag) 4 is not taken off. In addition, although the filter 13 is attached to the suction port side of the pipe 12, the filter 13 can be omitted.
　これに対し、図３に示すように、環状壁１１ａ1よりもアダプタ本体先端１１ｂ2側の部分（上側筒状部）１１ａ3は、シリンダ８の吸入筒８ａを全周に亘って取り囲んでいる。更に、上側筒状部１１ａ3は、図５に示すように、その内周面１１ｆ1によって、吸入筒８ａの外周面８ｆ1を全周に亘って密封状態に保持する。これにより、内層体４に充填された内溶液は、押圧ヘッド１０の押し込み及び復元の繰り返しにより、筒状部１１ａの内側に形成された開口部Ａ11からシリンダ８の吸入口Ａ8を通して充填空間Ｒ3に導入される。 On the other hand, as shown in FIG. 3, a portion (upper cylindrical portion) 11a 3 on the adapter body tip 11b 2 side of the annular wall 11a 1 surrounds the suction cylinder 8a of the cylinder 8 over the entire circumference. . Further, as shown in FIG. 5, the upper cylindrical portion 11a 3 holds the outer peripheral surface 8f 1 of the suction cylinder 8a in a sealed state over the entire circumference by the inner peripheral surface 11f 1 thereof. Thus, the solution among filled in the inner body 4, filling space by pushing and restoration repetition of the pressing head 10, from the opening A 11 formed inside the cylindrical portion 11a through the suction port A 8 of the cylinder 8 Introduced into R 3 .
　このように、本形態では、アダプタ本体先端１１ｂ2に、ポンプユニット７のシリンダ本体先端８ｂ2に設けた吸入筒８ａを全周に亘って取り囲む筒状部１１ａを設け、この筒状部１１ａの内周面１１ｆ1によって、シリンダ８の吸入筒８ａの外周面８ｆ1を全周に亘って密封状態に保持することから、内層体４に充填された内容液が、アダプタ１１とシリンダ８との間を通って収納空間Ｒ４に流入することを阻止することができる。このため、開口部Ａ11から流入した内容液がシリンダ本体８ｂの外周面に付着することで生じる汚れは極力抑えられる。 Thus, in this embodiment, the adapter body distal end 11b 2, the cylindrical portion 11a surrounding over the suction tube 8a provided in the cylinder main body distal end 8b 2 of the pump unit 7 on the entire circumference is provided, of the cylindrical portion 11a Since the outer peripheral surface 8f 1 of the suction cylinder 8a of the cylinder 8 is held in a sealed state by the inner peripheral surface 11f 1 , the content liquid filled in the inner layer body 4 is allowed to flow between the adapter 11 and the cylinder 8. it can be prevented from flowing into the accommodating space R 4 passes between. Therefore, dirt content liquid which has flowed from the opening portion A 11 is caused by adhering to the outer peripheral surface of the cylinder body 8b is minimized.
　また、本形態では、アダプタ本体先端１１ｂ2に設けた筒状部１１ａの内周面１１ｆ1によって、シリンダ８の吸入筒８ａの外周面８ｆ1が全周に亘って密封状態に保持されるため、使用者は、パッキン等の、弾性変形（押し潰し）を要するシール材を設けることなく、シリンダ８とアダプタ１１との間を密封することができる。このため、使用者は、シール材の押し潰しに要する大きな力を働かせることなく、シリンダ８の吸入筒８ａをアダプタ１１の筒状部１１ａの内側に嵌合させるだけの簡単な作業で、シリンダ８とアダプタ１１との間を密封することができる。 Further, in this embodiment, the outer peripheral surface 8f 1 of the suction cylinder 8a of the cylinder 8 is held in a sealed state over the entire circumference by the inner peripheral surface 11f 1 of the cylindrical portion 11a provided at the adapter main body tip 11b 2. The user can seal between the cylinder 8 and the adapter 11 without providing a sealing material such as packing that requires elastic deformation (crushing). For this reason, the user can perform the cylinder 8 by simply fitting the suction cylinder 8a of the cylinder 8 inside the cylindrical portion 11a of the adapter 11 without exerting a large force required for crushing the sealing material. And the adapter 11 can be sealed.
　更に、本形態では、筒状部１１ａの内周面１１ｆ1によって、吸入筒８ａの外周面８ｆ1が全周に亘って密封状態に保持されるため、図５に示すように、アダプタ本体先端１１ｂ2と、シリンダ本体先端８ｂ2との間に軸線Ｏ方向に沿って間隔Ｄ1を設けることで、アダプタ本体１１ｂとシリンダ本体８ｂとの間に隙間Ｃ1を形成している。これにより、使用者は、シリンダ８とアダプタ１１との接触面積が減少する分、更に小さな力で、シリンダ８の吸入筒８ａをアダプタ１１の筒状部１１ａ3の内側に嵌合させることができる。 Furthermore, in this embodiment, since the outer peripheral surface 8f 1 of the suction cylinder 8a is held in a sealed state over the entire circumference by the inner peripheral surface 11f 1 of the cylindrical portion 11a, as shown in FIG. and 11b 2, by providing the distance D 1 along the axis O direction between the cylinder body tip 8b 2, to form a gap C 1 between the adapter body 11b and the cylinder body 8b. Thus, the user, correspondingly the contact area between the cylinder 8 and the adapter 11 is reduced, it is possible to further with a small force, fitted suction tube 8a of the cylinder 8 to the inside of the cylindrical portion 11a 3 of the adapter 11 .
　従って、本形態によれば、ポンプユニット７のシリンダ８を内容器３の口部（内層体口部４ａ，外層体口部５ａ）に設けたアダプタ１１に容易に密封保持することができることで、内容器３として採用されたデラミネーション容器の機能を有効に発揮させることでき、しかも、シリンダ８とアダプタ１１との間の密封性にバラつきを生じ難い、新規なポンプ付き二重ボトルを提供することができる。 Therefore, according to this embodiment, the cylinder 8 of the pump unit 7 can be easily sealed and held in the adapter 11 provided in the mouth portion (the inner layer body mouth portion 4a, the outer layer body mouth portion 5a) of the inner container 3. To provide a novel double bottle with a pump that can effectively exert the function of a delamination container adopted as an inner container 3 and that hardly causes variations in the sealing performance between the cylinder 8 and the adapter 11. Can do.
　なお、内容液を充填済みの内容器３を充填品として何らかの方法でシールして輸送し、その後、別途、ポンプユニット７を差し込んで使用する場合、ポンプユニット７を差し込んだ時に液溢れを起こすことがある。これは、内容液の粘度が高く流動性が低いため、内容器３を横倒しに搬送すると、液線（液面）がすぐには水平にならないことが原因であると考えられる。 In addition, when the inner container 3 filled with the content liquid is sealed and transported in some way as a filled product, and then used separately with the pump unit 7 inserted, the liquid overflows when the pump unit 7 is inserted. There is. This is thought to be because the liquid line (liquid level) does not immediately become horizontal when the inner container 3 is transported sideways because the viscosity of the content liquid is high and the fluidity is low.
　また、本形態では、図１に示すように、アダプタ本体１１ｂの内周面と、シリンダ本体８ｂの外周面との間に全周に亘って隙間Ｃ2が設けられている。加えて、本形態では、図５に示すように、アダプタ本体先端１１ｂ2に繋がる先端側内周面１１ｆ2とシリンダ本体先端８ｂ2に繋がる先端側外周面８ｆ2とをそれぞれ、互いに全周に亘って密封状態に保持するシール面として構成している。 Further, in this embodiment, as shown in FIG. 1, the inner peripheral surface of the adapter body 11b, a gap C 2 is provided over the entire circumference between the outer peripheral surface of the cylinder body 8b. In addition, in this embodiment, as shown in FIG. 5, the front end side inner peripheral surface 11f 2 connected to the adapter main body front end 11b 2 and the front end side outer peripheral surface 8f 2 connected to the cylinder main body front end 8b 2 are arranged around the entire circumference. It is configured as a sealing surface that is held in a sealed state.
　かかる構成によれば、使用者がシリンダ８の吸入筒８ａをアダプタ１１の筒状部１１ａ3の内側に嵌合させるに際して必要となる力の増加を抑えつつ、シリンダ８とアダプタ１１との間の密封性にバラつきを生じ難い、更に密封性に優れたポンプ付き二重ボトルを提供することができる。 According to such a configuration, while suppressing an increase in required to become a force upon the user to fit inside of the cylindrical portion 11a 3 of the suction tube 8a adapter 11 of the cylinder 8, between the cylinder 8 and the adapter 11 It is possible to provide a double bottle with a pump which is less likely to cause variations in sealing performance and which is further excellent in sealing performance.
　なお、本形態では、図５に示すように、アダプタ本体先端１１ｂ2に繋がる周壁部１１ｂ3の内周面（以下、「先端側内周面」）１１ｆ2と、シリンダ本体先端８ｂ2に繋がる周壁部８ｂ3のうち、シリンダ本体先端８ｂ2側を周方向に全周に亘って切り欠いてなる環状凹部８ｂ4の外周面（以下、「先端側外周面」）８ｆ2とを、互いに全周に亘って密封状態に保持するシール面として構成している。但し、本発明に従えば、これに限定されるものではなく、例えば、環状凹部８ｂ4を形成することなく、周壁部８ｂ3の外周面を直接、先端側外周面８ｆ2とすることも可能である。 In the present embodiment, as shown in FIG. 5, the inner peripheral surface of the peripheral wall portion 11b 3 connected to the adapter body distal end 11b 2 (hereinafter, "front end side inner peripheral surface") and 11f 2, leading to the cylinder body tip 8b 2 Out of the peripheral wall portion 8b 3 , the outer peripheral surface (hereinafter referred to as “front end side outer peripheral surface”) 8f 2 of the annular recess 8b 4 formed by cutting out the cylinder body front end 8b 2 side in the circumferential direction over the entire circumference is mutually connected. It is configured as a sealing surface that is held in a sealed state over the circumference. However, according to the present invention, the present invention is not limited to this. For example, the outer peripheral surface of the peripheral wall portion 8b 3 can be directly used as the front end side outer peripheral surface 8f 2 without forming the annular recess 8b 4. It is.
　更に、本形態では、図５に示すように、アダプタ本体１１ｂの先端側内周面１１ｆ2に、シリンダ本体８ｂの先端側外周面８ｆ2に設けた凹部ｎと着脱可能に嵌合する凸部ｐが設けられている。かかる構成によれば、凸部ｐを凹部ｎに嵌合させたときの感覚により、筒状部１１ａの内周面１１ｆ1によって、吸入筒８ａの外周面８ｆ1を全周に亘って密封状態に保持されているかどうかを確認することができる。 Furthermore, in this embodiment, as shown in FIG. 5, a convex portion detachably fitted to the concave portion n provided on the distal end side outer peripheral surface 8f 2 of the cylinder main body 8b on the distal end side inner peripheral surface 11f 2 of the adapter main body 11b. p is provided.
