Description

本発明は、詰め替え容器に関する。   The present invention relates to a refill container.

この種の詰め替え容器として、従来、例えば下記特許文献1に記載されているような、本容器に詰め替える内容物が収容される容器本体と、容器本体の口部に装着され、該口部を閉塞する中栓と、を備え、中栓を本容器の口部に螺着させた状態で詰め替えを行う詰め替え容器が知られている。この中栓には、内容物を注出するための注出口が形成されているとともに、該注出口を閉塞するシール部が設けられている。シール部は、例えばプルトップが付設された蓋体からなる。
上記した詰め替え容器では、まずプルトップを引き上げて中栓の注出口を開封する。続いて、詰め替え容器を正立姿勢(口部が上向きの姿勢)に配置し、該詰め替え容器の中栓に、倒立姿勢(口部が下向きの姿勢)とされた本容器の口部を螺着する。そしてこの状態から、詰め替え容器と本容器とを上下反転させて、本容器を正立姿勢にするとともに詰め替え容器を倒立姿勢にする。これにより、詰め替え容器内の内容物が、詰め替え容器及び本容器の各口部の内側を流通して本容器内に詰め替えられる。
Conventionally, as this type of refill container, as described in, for example, Patent Document 1 below, a container body that contains the contents to be refilled in this container and a mouth portion of the container body are mounted, and the mouth portion is closed. There is known a refill container that is refilled in a state in which the inner plug is screwed to the mouth of the container. The inside plug is formed with a spout for pouring out the contents, and is provided with a seal portion for closing the spout. The seal portion is made of, for example, a lid provided with a pull top.
In the above-mentioned refill container, first, the pull top is pulled up to open the spout of the inner plug. Subsequently, the refill container is placed in an upright position (the mouth is in an upward position), and the mouth of this container in an inverted position (the mouth is in a downward position) is screwed onto the inner plug of the refill container. To do. From this state, the refill container and the main container are turned upside down to bring the main container into an upright posture and the refill container into an inverted posture. As a result, the contents in the refill container are refilled into the main container through the insides of the mouths of the refill container and the main container.

しかしながら、上記した従来の詰め替え容器では、中栓の注出口を開封した後、中栓に本容器の口部を螺着し、その後、詰め替え容器と本容器とを上下反転させる必要があるので、詰め替え作業が煩雑となっていた。
また、中栓の注出口を開封した後に、該中栓に対して本容器の口部を螺着するため、その螺合作業中に誤って詰め替え容器を倒すと、詰め替え容器内の内容物がこぼれ出るおそれがあった。
さらに、中栓に本容器の口部を螺着する際には、該本容器を倒立姿勢にするため、本容器内に内容物が残留していると、該内容物がこぼれるおそれがある。従って、本容器内の内容物を使い切った後でないと、詰め替え作業を行い難かった。
However, in the above-described conventional refill container, after opening the spout of the inner stopper, it is necessary to screw the mouth of the main container into the inner stopper, and then it is necessary to turn the refill container and the main container upside down. Refilling work was complicated.
In addition, after opening the spout of the inner plug, the mouth of the container is screwed to the inner plug, so if the refill container is accidentally tilted during the screwing operation, the contents in the refill container are There was a risk of spilling out.
Furthermore, when the mouth of the container is screwed onto the inner plug, the container is turned upside down, so that the contents may spill if the contents remain in the container. Therefore, it was difficult to perform the refilling work unless the contents in the container were used up.

本発明は、このような事情を考慮してなされたもので、その目的は、詰め替え作業を簡便に行うことができるうえ、詰め替え時に内容物をこぼし難く、また、本容器内の内容物が残留している場合であっても詰め替え作業を行うことができる詰め替え容器を提供することである。   The present invention has been made in consideration of such circumstances, and its purpose is to allow easy refilling work, to prevent the contents from spilling during refilling, and for the contents in the container to remain. The present invention is to provide a refill container that can be refilled even when it is being used.

上記の目的を達成するために、この発明は以下の手段を提供している。
本発明に係る詰め替え容器は、本容器に詰め替える内容物が収容される容器本体と、前記容器本体の口部から容器軸方向に沿った該容器本体の外側に向けて延在するとともに、前記本容器の注入口内に差し込み可能とされ、かつ先端部に注出口が形成された注出筒と、前記注出口に着脱自在に嵌合するとともに、前記注出筒に連結された閉塞板と、前記閉塞板に連結された操作突片と、を備え、前記操作突片は、前記注出筒の径方向の外側に配置され、容器軸方向に沿った前記容器本体の外側に向けて開口して前記本容器の注入口の開口端縁に係止するフック部と、一端部が前記閉塞板に連結され、かつ他端部が前記フック部に連結された突片本体と、を備え、前記注出筒の径方向において、前記注出筒における前記突片本体の一端部を挟んで前記突片本体の他端部と反対側となる部分には、容器軸方向に沿った前記容器本体の外側に向かって突出する突設片が配設され、前記突設片および前記突片本体の一端部には、これらを互いに離脱可能に係合させる係合部が形成されていることを特徴とする。
In order to achieve the above object, the present invention provides the following means.
The refill container according to the present invention includes a container main body in which contents to be refilled in the main container are accommodated, and extends from the mouth of the container main body toward the outside of the container main body along the container axial direction. A pouring tube that can be inserted into the inlet of the container and has a spout formed at the tip thereof; and a closure plate that is detachably fitted to the spout and connected to the pouring tube; An operation protrusion connected to a closing plate, and the operation protrusion is disposed on a radially outer side of the dispensing tube and opens toward the outer side of the container body along a container axial direction. A hook portion that engages with an opening edge of the inlet of the main container, and a projecting piece body having one end connected to the closing plate and the other end connected to the hook. In the radial direction of the outlet cylinder, the one end portion of the protruding piece main body of the outlet cylinder is sandwiched A protruding piece that protrudes toward the outside of the container main body along the container axial direction is disposed on a portion opposite to the other end of the protruding piece main body, and the protruding piece and the protruding piece main body An engaging portion is formed at one end of the detachable portion so as to detachably engage with each other.

本発明に係る詰め替え容器によれば、注出筒の径方向の外側に配置された突片本体の他端部にフック部が形成されているので、該フック部を本容器の注入口の開口端縁に係止させながら、注出筒を本容器の注入口に対して向かい合わせに配置することができる。そのため、容器本体と本容器とを容器軸方向に沿って相対的に接近移動させることで、注出筒を本容器の内側に差し込むように移動させることができる。このとき、フック部が本容器に係止されているので、本容器の内側への注出筒の移動に伴って、突片本体が徐々に張った状態となり、しだいに該突片本体を介して閉塞板に引張力を作用させることができる。
これにより、閉塞板を開封作動させて閉塞していた注出口を開放させることができる。その結果、注出口を通じて容器本体内の内容物を本容器内に注出することができ、本容器内への詰め替えを行うことができる。
以上のように、フック部を本容器に係止した状態で、詰め替え容器と本容器とを容器軸方向に沿って相対的に接近移動させるという簡便な作業によって、内容物を詰め替えることができる。
しかも、フック部を本容器に係止した後であっても、容器本体と本容器とを容器軸方向に沿って相対的に接近移動させるまでは、注出口は閉塞板によって閉塞されているので、詰め替え前の段階で容器本体内の内容物がこぼれることがない。
さらに、本容器を倒立姿勢にせず、未開封の詰め替え容器を倒立姿勢にして詰め替え作業を行うので、例えば本容器内の内容物が残留している場合であっても、内容物の詰め替え作業を行うことができる。
そして、突設片および突片本体の一端部に形成された係合部により、閉塞板に不意に外力が加えられても、突設片および突片本体の一端部の相対的な位置がずれることを抑制することが可能になり、閉塞板が不意の外力によって注出口から外れることを抑えることができる。
また、突設片および突片本体の一端部に形成された係合部により、閉塞板の閉塞状態を維持可能になるとともに、フック部に連なる突片本体を注出筒の本容器への差し込みに伴い引いて係合部の係合を解除することで、閉塞板を容易かつ確実に開封可能とし、内容物の詰め替え作業を効率よく行うことができる。
According to the refill container according to the present invention, since the hook portion is formed at the other end portion of the projecting piece main body disposed on the radially outer side of the dispensing tube, the hook portion is opened to the inlet of the container. While being locked to the end edge, the dispensing cylinder can be disposed facing the inlet of the container. Therefore, by moving the container body and the main container relatively closer along the container axial direction, the dispensing tube can be moved so as to be inserted into the inner side of the main container. At this time, since the hook portion is locked to the main container, the projecting piece main body is gradually stretched with the movement of the dispensing tube to the inner side of the main container, and gradually, through the main projecting piece body. Thus, a tensile force can be applied to the closing plate.
Thereby, the spout which has been closed by opening the closing plate can be opened. As a result, the contents in the container main body can be poured into the main container through the spout and can be refilled into the main container.
As described above, the contents can be refilled by a simple operation of relatively moving the refill container and the main container along the container axial direction while the hook portion is locked to the main container.
Moreover, even after the hook portion is locked to the main container, the spout is blocked by the closing plate until the main body and the main container are relatively moved along the container axial direction. In the stage before refilling, the contents in the container body will not spill.
Furthermore, since the refilling operation is performed with the unopened refilling container placed in an inverted posture without placing the container in an inverted posture, for example, even if the contents in the container remain, It can be carried out.
And even if an external force is unexpectedly applied to the closing plate by the engaging portion formed at one end of the protruding piece and the protruding piece main body, the relative positions of the protruding piece and one end of the protruding piece main body shift. It becomes possible to suppress this, and it can suppress that a closure board remove | deviates from a spout by unexpected external force.
In addition, the closing portion of the closing plate can be maintained by the protruding piece and the engaging portion formed at one end of the protruding piece body, and the protruding piece body connected to the hook portion is inserted into the main container of the dispensing cylinder. By pulling along with this, the engagement portion is disengaged, so that the closing plate can be opened easily and reliably, and the contents can be refilled efficiently.

本発明では、前記注出筒内には、容器軸方向に延びるとともに、内径が前記注出筒の内径より小さい空気置換筒が配設され、前記注出筒および空気置換筒は、互いに一体に形成されている構成でもよい。
この場合、注出口から本容器内に内容物が注出される際に、本容器内の空気の一部が空気置換筒を通じて詰め替え容器内に導入される。このため、本容器内のエア抜きと詰め替え容器内の負圧の抑制とを同時に行うことができ、内容物の詰め替え作業をよりスムーズに行うことができる。
In the present invention, an air replacement cylinder extending in the container axial direction and having an inner diameter smaller than the inner diameter of the extraction cylinder is disposed in the extraction cylinder, and the extraction cylinder and the air replacement cylinder are integrated with each other. The formed structure may be sufficient.
In this case, when the contents are poured out from the spout into the container, a part of the air in the container is introduced into the refill container through the air replacement cylinder. For this reason, it is possible to perform air bleeding in the main container and suppression of negative pressure in the refill container at the same time, and the contents can be refilled more smoothly.

本発明によれば、詰め替え作業を簡便に行うことができるうえ、詰め替え時に内容物をこぼし難く、また、本容器内の内容物が残留している場合であっても詰め替え作業を行うことができる。   According to the present invention, the refilling operation can be easily performed, the contents are not easily spilled at the time of refilling, and the refilling operation can be performed even when the contents in the container remain. .

以下、図面を参照し、本発明の一実施形態に係る詰め替え容器1について説明する。
図1及び図2に示すように、本実施形態の詰め替え容器1は、本容器Aに詰め替える内容物N(何れも図4〜図6参照)が収容される有底筒状の容器本体2と、本容器Aの注入口1A内に差し込み可能とされ、先端部に注出口3aが形成された注出筒3と、該注出筒3の注出口3aを閉塞する閉塞板4と、該閉塞板4に連結された操作突片5と、を備えている。
Hereinafter, with reference to drawings, refill container 1 concerning one embodiment of the present invention is explained.
As shown in FIG.1 and FIG.2, the refill container 1 of this embodiment is the bottomed cylindrical container main body 2 in which the content N (all refer FIGS. 4-6) accommodated in this container A is accommodated. The pouring cylinder 3 which can be inserted into the injection port 1A of the main container A and has the pouring port 3a formed at the tip, the closing plate 4 for closing the pouring port 3a of the pouring tube 3, and the blocking And an operation projection piece 5 connected to the plate 4.

なお、上述した容器本体2及び注出筒3は、それぞれの中心軸線が共通軸上に位置された状態で配設されている。本実施形態では、この共通軸を容器軸Oといい、図1に示す正立姿勢にある詰め替え容器1において、容器軸Oに沿った注出筒3側を上側、容器本体2側を下側という。また、容器軸O方向から見た平面視において、容器軸Oに直交する方向を径方向といい、容器軸O回りに周回する方向を周方向という。   In addition, the container main body 2 and the extraction cylinder 3 described above are arranged in a state where the respective central axes are located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, and in the refillable container 1 in the upright posture shown in FIG. 1, the dispensing cylinder 3 side along the container axis O is the upper side, and the container body 2 side is the lower side. That's it. Further, in a plan view viewed from the container axis O direction, a direction orthogonal to the container axis O is referred to as a radial direction, and a direction around the container axis O is referred to as a circumferential direction.

容器本体2における口部2a及び胴部2bは、それぞれ円筒状に形成されている。
注出筒3は、容器本体2の口部2aから容器軸O方向に沿って上方に向けて延在する筒状に形成されている。注出筒3は、下端部に連結された装着筒10を介して容器本体2の口部2aに装着されている。注出筒3の上端開口は注出口3aとなっている。
The mouth part 2a and the body part 2b in the container body 2 are each formed in a cylindrical shape.
The dispensing cylinder 3 is formed in a cylindrical shape extending upward from the mouth portion 2a of the container body 2 along the container axis O direction. The dispensing cylinder 3 is attached to the mouth 2a of the container body 2 via an attachment cylinder 10 connected to the lower end. The upper end opening of the dispensing cylinder 3 is a dispensing outlet 3a.

注出筒3は、周方向に沿って湾曲した湾曲壁部41と、湾曲壁部41の両周端部同士を連結する平坦壁部42と、により構成されている。注出筒3は、容器軸Oに直交する横断面視形状がD字状となっている。注出筒3の内側には、容器軸Oに対して平坦壁部42の反対側にずれた位置に、容器軸Oに沿って延びる空気置換筒6が配置されている。空気置換筒6は、架設部6aを介して湾曲壁部41の内周面に支持されている。空気置換筒6は、その上端開口が注出筒3の上端開口面3b上に位置し、下端開口が注出筒3の下端を超えて装着筒10の内側、すなわち容器本体2の口部2aの内側に位置するように配設されている。空気置換筒6は、湾曲壁部41の内周側における例えば周方向の中央部に配置されているが、周方向の中央部を避けて配置されてもよい。
なお、空気置換筒6は、平坦壁部42の内周側に配置されるとより良い。すなわち、空気置換筒6が平坦壁部42側に配置される場合、湾曲壁部41側から開く閉塞板4の開動作にて内容物Nの吐出が先に行われ、その後に空気置換筒6を通じて空気の置換がなされるため、空気置換筒6内への内容物Nの入り込みを抑制することが可能になる。
The dispensing cylinder 3 is configured by a curved wall portion 41 that is curved along the circumferential direction, and a flat wall portion 42 that connects both peripheral ends of the curved wall portion 41. The dispensing cylinder 3 has a D-shaped cross-sectional view perpendicular to the container axis O. An air replacement cylinder 6 extending along the container axis O is disposed inside the extraction cylinder 3 at a position shifted to the opposite side of the flat wall portion 42 with respect to the container axis O. The air replacement cylinder 6 is supported on the inner peripheral surface of the curved wall part 41 via the erection part 6a. The upper end opening of the air replacement cylinder 6 is positioned on the upper end opening surface 3b of the dispensing cylinder 3, and the lower end opening extends beyond the lower end of the dispensing cylinder 3, inside the mounting cylinder 10, that is, the mouth 2a of the container body 2. It is arrange | positioned so that it may be located inside. The air replacement cylinder 6 is disposed at, for example, the central portion in the circumferential direction on the inner peripheral side of the curved wall portion 41, but may be disposed away from the central portion in the circumferential direction.
Note that the air replacement cylinder 6 is better disposed on the inner peripheral side of the flat wall portion 42. That is, when the air replacement cylinder 6 is arranged on the flat wall portion 42 side, the contents N are discharged first by the opening operation of the closing plate 4 opened from the curved wall portion 41 side, and thereafter the air replacement cylinder 6 Since the air is replaced through the air N, the entry of the contents N into the air replacement cylinder 6 can be suppressed.

装着筒10は、注出筒3より大径に形成されるとともに、容器本体2の口部2aに打栓嵌合(アンダーカット嵌合)された周壁部11と、注出筒3の下端部と周壁部11の上端部とを連結し、かつ口部2aの開口端縁上に配置された環状のフランジ部13と、を備えている。   The mounting cylinder 10 is formed to have a larger diameter than the pouring cylinder 3, and a peripheral wall portion 11 that is plugged (undercut fitted) into the mouth portion 2 a of the container body 2, and a lower end portion of the pouring cylinder 3. And an annular flange portion 13 that connects the upper end portion of the peripheral wall portion 11 and is disposed on the opening edge of the mouth portion 2a.

なお、フランジ部13には、容器本体2の口部2aの内側に嵌合するシール筒14が形成されている。シール筒14は、口部2aと装着筒10との間を例えば液密にシールしている。また、図示の例では、周壁部11を容器本体2の口部2aにアンダーカット嵌合させたが、この場合に限定されるものではなく、例えば螺着しても構わない。さらに、注出筒3が容器本体2の口部2aに一体形成または一体接合される構成でもよい。   The flange portion 13 is formed with a seal cylinder 14 that fits inside the mouth portion 2a of the container body 2. The seal cylinder 14 seals, for example, liquid tightly between the mouth portion 2a and the mounting cylinder 10. Further, in the illustrated example, the peripheral wall portion 11 is undercut fitted to the mouth portion 2a of the container body 2. However, the present invention is not limited to this case, and may be screwed, for example. Furthermore, the structure by which the extraction | pouring cylinder 3 is integrally formed or integrally joined to the opening 2a of the container main body 2 may be sufficient.

注出筒3の湾曲壁部41の外径は、本容器Aの注入口1Aの内径より小さくなっている。注出口3aが位置する注出筒3の上端開口面3bは、容器軸Oに直交する水平方向に沿って延在している。
なお、注出筒3の上端開口面3bは、容器軸Oに対して傾斜する方向に延在してもよく、または下方若しくは上方に向けて凸の曲面状に形成されてもよく、または階段状若しくは波形状に形成されてもよい。
The outer diameter of the curved wall portion 41 of the dispensing tube 3 is smaller than the inner diameter of the inlet 1A of the main container A. An upper end opening surface 3b of the dispensing cylinder 3 where the dispensing outlet 3a is located extends along a horizontal direction orthogonal to the container axis O.
In addition, the upper end opening surface 3b of the pouring cylinder 3 may extend in a direction inclined with respect to the container axis O, or may be formed in a curved surface convex downward or upward, or a staircase It may be formed in a shape or a wave shape.

閉塞板4は、注出口3aの形状に倣って形成されて該注出口3aを閉塞している。閉塞板4が注出口3aを閉塞したとき、後述する保護突片16および突片本体20の一端部20aが互いに離脱可能に係合する。以下、特に記載がなければ、閉塞板4が注出口3aを閉塞したときの構成について説明する。
なお、注出口3aを閉塞した閉塞板4に開方向又は注出筒3内への押し込み方向への付勢力が作用する構成であっても、係合部30によって閉塞板4が注出口3aを閉塞した閉塞状態に維持される。
The closing plate 4 is formed following the shape of the spout 3a and closes the spout 3a. When the closing plate 4 closes the spout 3a, a protection protruding piece 16 and an end 20a of the protruding piece body 20 described later are detachably engaged with each other. Hereinafter, unless otherwise specified, the configuration when the closing plate 4 closes the spout 3a will be described.
Even if the urging force in the opening direction or the pushing direction into the dispensing cylinder 3 is applied to the closing plate 4 that has closed the outlet 3a, the closing plate 4 causes the outlet 3a to be blocked by the engaging portion 30. The closed state is maintained.

注出口3aの上面視形状は、注出筒3の横断面視における内周形状と同じになっている。閉塞板4の上面視形状は、注出口3aの上面視形状と同等形状とされるとともに、注出口3aよりも一回り大きい形状とされている。閉塞板4は、注出筒3の上端開口縁に当接している。閉塞板4の下面には、上面視形状が注出口3aの上面視形状と同様とされて注出口3a内に嵌合するシール筒24が形成されている。シール筒24は、閉塞板4と注出筒3との間を例えば液密にシールしている。また、閉塞板4の下面には、空気置換筒6の上端開口の内側に嵌合するシール突部24aが形成されている。   The top view shape of the spout 3 a is the same as the inner peripheral shape of the pour cylinder 3 in a cross-sectional view. The top view shape of the blocking plate 4 is the same shape as the top view shape of the spout 3a and is slightly larger than the spout 3a. The closing plate 4 is in contact with the upper end opening edge of the dispensing cylinder 3. A sealing cylinder 24 is formed on the lower surface of the closing plate 4 so that the shape in top view is the same as the shape in top view of the spout 3a and is fitted into the spout 3a. The seal cylinder 24 seals, for example, liquid tightly between the closing plate 4 and the extraction cylinder 3. Further, a seal projection 24 a that fits inside the upper end opening of the air replacement cylinder 6 is formed on the lower surface of the closing plate 4.

閉塞板4は、注出筒3の上端部のうち、上面視で直線状をなす部分、すなわち平坦壁部42の上端部にヒンジ部(例えば弾性ヒンジ)31を介して連結されている。なお、図2中線31aはヒンジ部31の回動中心軸線を示す。回動中心軸線31aは、詰め替え容器1の上面視で、平坦壁部42に沿って真直ぐに延びている。図1に示すように、平坦壁部42の上部には、径方向の内側に向けてくぼむくぼみ部42aが形成されている。   The closing plate 4 is connected to a portion of the upper end portion of the dispensing cylinder 3 that is linear in a top view, that is, an upper end portion of the flat wall portion 42 via a hinge portion (for example, an elastic hinge) 31. In FIG. 2, a line 31 a indicates the rotation center axis of the hinge portion 31. The rotation center axis 31 a extends straight along the flat wall portion 42 in a top view of the refill container 1. As shown in FIG. 1, a recessed portion 42 a is formed in the upper portion of the flat wall portion 42 so as to be recessed inward in the radial direction.

閉塞板4は、容器軸Oに直交する平板状に形成されている。閉塞板4の上面には、側面視三角形状の補強リブ7が立設されている。補強リブ7の側面視形状を画成する三辺のうち、一辺は閉塞板4の上面上に位置し、他の一辺7a(以下、起立辺7aという。)は閉塞板4の上面から上方に延びて突片本体20の一端部20aに径方向で対向し、残りの一辺7b(以下、傾斜辺7bという。)は起立辺7aの上端から突片本体20の他端部20b側に向かうに従い漸次下方に位置するように延びている。起立辺7aの上端(傾斜辺7bとの交点)は、補強リブ7の頂部7cを形成する。図示の例では、傾斜辺7bの下端は閉塞板4の上面およびヒンジ部31に段差なく連なっている。補強リブ7は、上面視で突片本体20と重なるように配設されている。補強リブ7の起立辺7aと突片本体20の一端部20aとは、径方向で互いに離間している。   The closing plate 4 is formed in a flat plate shape orthogonal to the container axis O. On the upper surface of the closing plate 4, reinforcing ribs 7 having a triangular shape in a side view are erected. Of the three sides defining the side view shape of the reinforcing rib 7, one side is located on the upper surface of the closing plate 4, and the other one side 7 a (hereinafter referred to as the standing side 7 a) is upward from the upper surface of the closing plate 4. It extends and faces one end 20a of the projecting piece main body 20 in the radial direction, and the remaining one side 7b (hereinafter referred to as an inclined side 7b) extends from the upper end of the standing side 7a toward the other end 20b of the projecting piece main body 20. It extends so as to be located gradually below. The upper end of the standing side 7 a (intersection with the inclined side 7 b) forms the top portion 7 c of the reinforcing rib 7. In the illustrated example, the lower end of the inclined side 7 b is connected to the upper surface of the closing plate 4 and the hinge portion 31 without a step. The reinforcing rib 7 is disposed so as to overlap the protruding piece main body 20 in a top view. The standing side 7a of the reinforcing rib 7 and the one end 20a of the protruding piece main body 20 are separated from each other in the radial direction.

操作突片5は、一端部20aが閉塞板4の外周縁部に連結され、かつ他端部20bが注出筒3の径方向外側に配置された帯状の突片本体20と、この突片本体20の他端部20bに連結され、上方に向けて開口するフック部21と、を備えている。   The operation projecting piece 5 has a band-shaped projecting piece main body 20 in which one end portion 20a is connected to the outer peripheral edge portion of the closing plate 4 and the other end portion 20b is arranged on the radially outer side of the extraction tube 3. A hook portion 21 connected to the other end portion 20b of the main body 20 and opening upward.

上面視において、突片本体20は、一端部20aから他端部20bに向けて直線状をなすように、容器軸Oを径方向に跨いで延びている。突片本体20の一端部20aは、容器軸Oを径方向に挟んだ他端部20bの反対側に位置している。突片本体20の一端部20aは、閉塞板4から上方に延在している。突片本体20の他端部20bは、閉塞板4よりも下方に位置している。突片本体20の一端部20aおよび他端部20bの間は、比較的弾性変形が容易な可撓部20cとされ、この可撓部20cの両端部が一端部20aおよび他端部20bにそれぞれ薄肉部20ca,20cbを介して接続されている。   When viewed from above, the protruding piece body 20 extends across the container axis O in the radial direction so as to form a straight line from the one end 20a to the other end 20b. One end portion 20a of the projecting piece main body 20 is located on the opposite side of the other end portion 20b with the container shaft O sandwiched in the radial direction. One end portion 20 a of the projecting piece body 20 extends upward from the closing plate 4. The other end 20 b of the projecting piece main body 20 is located below the closing plate 4. Between the one end portion 20a and the other end portion 20b of the projecting piece main body 20 is a flexible portion 20c that is relatively easily deformable, and both end portions of the flexible portion 20c are respectively connected to the one end portion 20a and the other end portion 20b. The thin-walled portions 20ca and 20cb are connected to each other.

操作突片5は、上面視で突片本体20およびフック部21の幅方向の中心線Lを容器軸Oと交差させて配置され、かつ中心線Lを注出筒3の平坦壁部42及び回動中心軸線31aと直交させるように配置されている。補強リブ7は、その厚み中心が上面視で中心線L上に位置するように配設されている。   The operation protrusion 5 is arranged with the center line L in the width direction of the protrusion main body 20 and the hook part 21 intersecting the container axis O in a top view, and the center line L is set to the flat wall part 42 of the dispensing cylinder 3 and It arrange | positions so that it may orthogonally cross with the rotation center axis line 31a. The reinforcing rib 7 is disposed so that the thickness center thereof is located on the center line L in a top view.

突片本体20の一端部20aは、閉塞板4から上方に向けて略直角に起立する。一端部20aの上端には、薄肉部20caを介して可撓部20cの一端が接続される。可撓部20cの他端は、薄肉部20cbを介して突片本体20の他端部20bの上端に接続される。可撓部20cは、側面視において、一端部20aの上端から補強リブ7の上方を該傾斜辺7bに沿うように斜めに延び、ヒンジ部31を詰め替え容器1の外側から覆いつつ、上方から下方に向けて径方向の外側に向けて凸となるように湾曲し、注出筒3の径方向外側で容器軸O方向に沿うように下方に向けて延びる。   One end portion 20a of the projecting piece main body 20 rises from the closing plate 4 upward at a substantially right angle. One end of the flexible portion 20c is connected to the upper end of the one end portion 20a through the thin portion 20ca. The other end of the flexible portion 20c is connected to the upper end of the other end portion 20b of the protruding piece body 20 via the thin portion 20cb. The flexible portion 20c extends obliquely from the upper end of the one end portion 20a to the upper side of the reinforcing rib 7 along the inclined side 7b and covers the hinge portion 31 from the outer side of the refill container 1 in the side view. It curves so that it may become convex toward the outer side of radial direction toward the outer side, and it extends toward the downward direction along the container axis O direction at the outer side of the pouring cylinder 3 in the radial direction.

ここで、容器本体2の口部2aに装着される注出筒3および装着筒10等を含む注出筒部材3Cは、合成樹脂を用いた一体成形品とされる。注出筒部材3Cは、図3に示すように、閉塞板4およびシール筒24の中心軸線が容器軸Oと並列かつ平行になるまで閉塞板4が開いた状態で成形される。このとき、突片本体20の可撓部20cは、下向きになった一端部20aから下方に延びた後に上方に湾曲し、フック部21の上方で再度下方に湾曲した後に他端部20bに至るように形成される。   Here, the extraction cylinder member 3 </ b> C including the extraction cylinder 3 and the installation cylinder 10 attached to the mouth portion 2 a of the container body 2 is an integrally molded product using a synthetic resin. As shown in FIG. 3, the dispensing cylinder member 3 </ b> C is molded in a state in which the closing plate 4 is opened until the central axes of the closing plate 4 and the seal cylinder 24 are parallel and parallel to the container axis O. At this time, the flexible portion 20c of the projecting piece main body 20 extends downward from the one end portion 20a that faces downward, then curves upward, and again curves downward above the hook portion 21 and then reaches the other end portion 20b. Formed as follows.

図1、図2を参照し、フック部21は、注出筒3の径方向の外側に配置され、突片本体20の他端部20bが上側から接続されている。フック部21は、突片本体20の他端部20bに接続されて下方に向けて突出する内側部21aと、内側部21aの下端から径方向の外側に延びる連結部21bと、連結部21bの径方向の外端から上方に向けて突出する外側部21cと、を備えている。   Referring to FIGS. 1 and 2, the hook portion 21 is disposed on the outer side in the radial direction of the dispensing cylinder 3, and the other end portion 20 b of the protruding piece main body 20 is connected from above. The hook portion 21 is connected to the other end portion 20b of the projecting piece body 20 and protrudes downward, a connecting portion 21b extending radially outward from the lower end of the inner portion 21a, and a connecting portion 21b. And an outer portion 21c protruding upward from the outer end in the radial direction.

フック部21は、帯状の突片本体20と同等幅をなし、側面視で鉤状に屈曲して延びる。フック部21の内側部21aは、突片本体20の一端部20aと同等の厚みとされ、フック部21の連結部21b及び外側部21cは、内側部21aよりも厚く形成されている。フック部21の内側部21aは、注出筒3の外周面に沿うように配置されている。フック部21の内側部21aは、破断可能なブリッジ部22を介して注出筒3の外周面に連結されている。本実施形態では、フック部21の内側部21aは、注出筒3の平坦壁部42の外側面に連結されている。   The hook portion 21 has the same width as that of the belt-like protruding piece main body 20, and is bent and extended in a hook shape in a side view. The inner portion 21a of the hook portion 21 has the same thickness as the one end portion 20a of the protruding piece body 20, and the connecting portion 21b and the outer portion 21c of the hook portion 21 are formed to be thicker than the inner portion 21a. The inner portion 21 a of the hook portion 21 is disposed along the outer peripheral surface of the dispensing cylinder 3. The inner portion 21 a of the hook portion 21 is connected to the outer peripheral surface of the dispensing tube 3 via a breakable bridge portion 22. In the present embodiment, the inner portion 21 a of the hook portion 21 is connected to the outer surface of the flat wall portion 42 of the dispensing cylinder 3.

注出筒3には、上方に向けて突出する保護突片(突設片)16が配設されている。保護突片16は、その上端部(先端部)が容器軸O方向で操作突片5の上端部よりも上方に位置している。この保護突片16により、例えば、詰め替え容器1が落下する等したときに、他の物体が、操作突片5ではなく、まず保護突片16に衝突しやすくなる。なお、保護突片16の上端部は、容器軸O方向の位置が操作突片5の上端部と同等であってもよい。   The extraction tube 3 is provided with a protective protrusion (projection piece) 16 that protrudes upward. The upper end portion (tip portion) of the protective projection piece 16 is positioned above the upper end portion of the operation projection piece 5 in the container axis O direction. For example, when the refill container 1 falls, the protective protrusion 16 makes it easier for other objects to collide with the protective protrusion 16 instead of the operation protrusion 5. Note that the upper end portion of the protective protrusion 16 may have the same position in the container axis O direction as the upper end portion of the operation protrusion 5.

保護突片16は、周方向に沿って湾曲する円弧状に形成され、注出筒3の湾曲壁部41の上方に連なるように形成される。保護突片16は、突片本体20の一端部20aの周囲を、径方向の外側から周方向の一定の範囲にわたって覆う。保護突片16は、その周方向の中央部が、径方向において、突片本体20の一端部20aを挟んで突片本体20の他端部20bと反対側となる部分に配設されている。   The protective protrusion 16 is formed in an arc shape that is curved along the circumferential direction, and is formed so as to be continuous above the curved wall portion 41 of the dispensing cylinder 3. The protection protrusion 16 covers the periphery of the one end 20a of the protrusion main body 20 over a certain range in the circumferential direction from the outside in the radial direction. The central portion in the circumferential direction of the protective protruding piece 16 is disposed in a portion on the opposite side to the other end portion 20b of the protruding piece body 20 across the one end portion 20a of the protruding piece body 20 in the radial direction. .

保護突片16は、注出筒3とともに、本容器Aの注入口1A内に差し込み可能に形成されている。保護突片16は、注出筒3の外周面から径方向の外側に突出しておらず、保護突片16の外周面は、周方向に沿って湾曲し、注出筒3の外周面とほぼ面一となっている。上面視において、保護突片16の周方向の中央部は、操作突片5の幅方向の中心線L上に配置されている。   The protective protrusion 16 is formed so as to be able to be inserted into the injection port 1 </ b> A of the container A together with the dispensing cylinder 3. The protective protruding piece 16 does not protrude radially outward from the outer peripheral surface of the dispensing cylinder 3, and the outer peripheral surface of the protective protruding piece 16 is curved along the circumferential direction and is substantially the same as the outer peripheral surface of the extracting cylinder 3. It is the same. In the top view, the central portion in the circumferential direction of the protective projection piece 16 is disposed on the center line L in the width direction of the operation projection piece 5.

突片本体20の一端部20aにおける径方向の外側、すなわち保護突片16側を向く外側面には、係止爪30aが突設されている。また、保護突片16の周方向の中央部には、係止爪30aを嵌入させる係止孔30bが形成されている。これら係止爪30a及び係止孔30bにより、突片本体20の一端部20aの上方移動ひいては閉塞板4の開封動作を規制する係合部30が構成される。
なお、本実施形態では、係合部30が構成されることで、閉塞板4に対して容器軸O方向に不意な外力が加えられた場合でも、閉塞板4が開状態になること、又は閉塞板4が注出筒3内に入り込むことを抑制している。
A locking claw 30a protrudes on the radially outer side of the one end portion 20a of the protruding piece body 20, that is, on the outer surface facing the protective protruding piece 16 side. Further, a locking hole 30b into which the locking claw 30a is fitted is formed in the central portion in the circumferential direction of the protective protruding piece 16. The engaging claw 30a and the engaging hole 30b constitute an engaging portion 30 that restricts the upward movement of the one end portion 20a of the projecting piece main body 20 and thus the opening operation of the closing plate 4.
In addition, in this embodiment, even when an unexpected external force is applied to the closing plate 4 in the container axis O direction by configuring the engaging portion 30, the closing plate 4 is in an open state, or The blocking plate 4 is prevented from entering the dispensing cylinder 3.

補強リブ7は、その起立辺7aが、突片本体20の一端部20aに対して径方向の内側に隙間s1を空けて配置される。突片本体20の一端部20aは、注出口を開封するために突片本体20の他端部20bが図1の下方に引き下げられた際に、径方向で他端部20b側に倒れるように弾性変形し、係止爪30aを保護突片16の係止孔30bから離脱させる(図5参照)。すなわち、係合部30の係合を解除する。このとき、補強リブ7の起立辺7aには、突片本体20における径方向で倒れた一端部20aが当接し、これ以上の一端部20aの倒れを抑止する。   The reinforcing rib 7 is arranged such that the rising side 7 a is spaced from the one end portion 20 a of the projecting piece main body 20 in the radial direction by a gap s 1. One end portion 20a of the projecting piece main body 20 is tilted to the other end portion 20b side in the radial direction when the other end portion 20b of the projecting piece main body 20 is pulled downward in FIG. 1 in order to open the spout. It is elastically deformed, and the locking claw 30a is detached from the locking hole 30b of the protective protrusion 16 (see FIG. 5). That is, the engagement portion 30 is disengaged. At this time, one end portion 20a that has fallen in the radial direction of the projecting piece main body 20 abuts on the rising side 7a of the reinforcing rib 7 to prevent further collapse of the one end portion 20a.

次に、上述したように構成された詰め替え容器1から本容器Aに内容物Nを詰め替える方法について、図4〜図6を参照して説明する。
図4を参照し、まず、詰め替え容器1を倒立姿勢にするとともに本容器Aを正立姿勢にした状態で、詰め替え容器1を本容器Aの上方に配置させる。そして、注出筒3を注入口1A内に差し込みつつ、突片本体20の他端部20bに連設されたフック部21を本容器Aの注入口1Aの開口端縁に係止させるように、詰め替え容器1と本容器Aとを組み合わせる。その際、保護突片16の外側面および注出筒3の湾曲壁部41の外周面は、注入口1Aの内周面との間に隙間s2を形成する。注出筒3が注入口1A内に進入すると、注出筒3の平坦壁部42の外側面は、注入口1Aの内周面に、突片本体20の他端部20bおよびフック部21の内側部21aを間に挟んで対向する。
Next, a method for refilling the contents N from the refill container 1 configured as described above into the main container A will be described with reference to FIGS.
With reference to FIG. 4, first, the refill container 1 is placed above the main container A in a state where the refill container 1 is in the inverted posture and the main container A is in the upright posture. Then, the hook portion 21 connected to the other end portion 20b of the projecting piece main body 20 is locked to the opening edge of the injection port 1A of the container A while inserting the dispensing tube 3 into the injection port 1A. The refill container 1 and the main container A are combined. At that time, a gap s2 is formed between the outer peripheral surface of the protective protruding piece 16 and the outer peripheral surface of the curved wall portion 41 of the dispensing tube 3 with the inner peripheral surface of the injection port 1A. When the extraction tube 3 enters the injection port 1A, the outer surface of the flat wall portion 42 of the extraction tube 3 is connected to the inner peripheral surface of the injection port 1A on the other end 20b of the protruding piece body 20 and the hook portion 21. Opposite the inner part 21a.

次いで、フック部21を本容器Aに係止させたままの状態で、詰め替え容器1と本容器Aとを容器軸O方向で相対的に接近移動させる。図5を参照し、このとき、フック部21を注出筒3の外周面に連結するブリッジ部22を破断させながら、注出筒3が本容器Aの内側にさらに差し込まれるように下方へ移動する。注出筒3は、湾曲壁部41の外周面と注入口1Aの内周面との間の隙間s2により、これらを近接若しくは当接させるように容器軸Oに対して斜めに変位可能である。   Next, the refill container 1 and the main container A are moved relatively close to each other in the container axis O direction while the hook portion 21 is kept locked to the main container A. Referring to FIG. 5, at this time, while the bridge portion 22 that connects the hook portion 21 to the outer peripheral surface of the extraction cylinder 3 is broken, the extraction cylinder 3 moves downward so as to be further inserted inside the container A. To do. The dispensing tube 3 can be displaced obliquely with respect to the container axis O so as to approach or abut against each other by a gap s2 between the outer peripheral surface of the curved wall portion 41 and the inner peripheral surface of the injection port 1A. .

このとき、フック部21が本容器Aに係止されているので、本容器Aの内側への注出筒3の移動に伴って、突片本体20には相対的にフック部21側へ引かれるように張力が作用する。突片本体20がフック部21側へ引かれることで、突片本体20の一端部20aには、他端部20b側へ倒れる方向の回動力が作用する。これにより、係止爪30aが保護突片16の係止孔30bから離脱して係合部30の係合が解除され、閉塞状態にある閉塞板4が開封可能な状態となる。   At this time, since the hook portion 21 is locked to the main container A, the protrusion piece body 20 is pulled toward the hook portion 21 side relatively with the movement of the extraction tube 3 to the inner side of the main container A. Tension acts as it is. When the projecting piece main body 20 is pulled toward the hook portion 21, a turning force in a direction of falling toward the other end portion 20 b acts on the one end portion 20 a of the projecting piece main body 20. Thereby, the latching claw 30a is detached from the latching hole 30b of the protective protrusion 16, the engagement of the engaging portion 30 is released, and the closed plate 4 in the closed state can be opened.

なお、例えば、突片本体20がフック部21側へ引かれて一端部20aが閉塞板4と略平行になるまで倒れてしまうと、突片本体20がフック部21側に引かれても閉塞板4に開封方向への回動力、換言すればモーメントが作用し難くなる。
これに対し、本実施形態では、突片本体20を引く力が閉塞板4から離間した補強リブ7の頂部7cに作用するので、閉塞板4に開封方向への回動力が作用し易い。またこのとき、閉塞板4に曲げが生じると閉塞板4への回動力が逃げてしまうが、閉塞板4は補強リブ7によって補強されているため、閉塞板4の曲げを抑えて閉塞板4を効率よく回動、開封させることが可能である。
For example, if the projecting piece main body 20 is pulled to the hook portion 21 side and falls down until the one end portion 20a is substantially parallel to the closing plate 4, the projecting piece main body 20 is closed even if the projecting piece main body 20 is pulled to the hook portion 21 side. The turning force in the opening direction, in other words, the moment hardly acts on the plate 4.
On the other hand, in this embodiment, since the force which pulls the protrusion piece main body 20 acts on the top part 7c of the reinforcement rib 7 spaced apart from the obstruction board 4, the rotational force in an opening direction acts on the obstruction board 4 easily. At this time, when bending occurs in the closing plate 4, the rotational force to the closing plate 4 escapes. However, since the closing plate 4 is reinforced by the reinforcing rib 7, the bending of the closing plate 4 is suppressed and the closing plate 4 is suppressed. Can be efficiently rotated and opened.

図6を参照し、そして、係合部30の係合が解除されて閉塞板4が開封方向に回動し、閉塞板4およびシール筒24により閉塞されていた注出口3aが開放することで、注出口3aを通じて容器本体2内の内容物Nが本容器A内に注出され、本容器A内への詰め替えを行うことが可能となる。   With reference to FIG. 6, the engagement portion 30 is disengaged, the closing plate 4 is rotated in the opening direction, and the spout 3 a closed by the closing plate 4 and the seal cylinder 24 is opened. The contents N in the container main body 2 are poured into the main container A through the spout 3a and can be refilled into the main container A.

注出筒3を注入口1A内に差し込んで注出口3aを開放した状態では、注入口1Aの開口端縁と装着筒10のフランジ部13の上面との間に、フック部21の連結部21bが挟み込まれる。これにより、注入口1Aの開口端縁と装着筒10のフランジ部13の上面との間に、連結部21bの厚み分の隙間s3が確保される。   In a state where the dispensing tube 3 is inserted into the injection port 1A and the dispensing port 3a is opened, the connecting portion 21b of the hook portion 21 is provided between the opening edge of the injection port 1A and the upper surface of the flange portion 13 of the mounting tube 10. Is caught. Thereby, a gap s3 corresponding to the thickness of the connecting portion 21b is ensured between the opening edge of the injection port 1A and the upper surface of the flange portion 13 of the mounting cylinder 10.

またこのとき、注出筒3の湾曲壁部41の外周面は、注入口1Aの内周面に近接若しくは当接するが、注出筒3の平坦壁部42の外側面と注入口1Aの内周面との間には隙間s4が形成される。これらの隙間s3,s4を通じて、注出口3aから本容器A内に内容物Nが注出される際に本容器A内の空気が本容器A外に排出される。   At this time, the outer peripheral surface of the curved wall portion 41 of the dispensing cylinder 3 is close to or abuts on the inner peripheral surface of the injection port 1A, but the outer surface of the flat wall portion 42 of the dispensing tube 3 and the inner surface of the injection port 1A A gap s4 is formed between the peripheral surface. When the contents N are poured out from the spout 3a into the main container A through the gaps s3 and s4, the air in the main container A is discharged out of the main container A.

また、本実施形態では、注出筒3の内側に、注出筒3と平行で注出筒3よりも細身かつ長尺の空気置換筒6が一体に設けられており、この空気置換筒6を通じて、注出口3aから本容器A内に内容物Nが注出される際に、本容器A内の空気の一部が詰め替え容器1内に導入される。このように、本容器A内の空気を本容器A外に排出するとともに詰め替え容器1内に導入することで、内容物Nの詰め替え作業を円滑に行うことが可能となる。   Further, in the present embodiment, an air replacement cylinder 6 that is narrower and longer than the extraction cylinder 3 is integrally provided inside the extraction cylinder 3 in parallel with the extraction cylinder 3. When the contents N are poured into the main container A from the spout 3a, a part of the air in the main container A is introduced into the refill container 1. As described above, by discharging the air in the main container A to the outside of the main container A and introducing it into the refill container 1, the refilling operation of the contents N can be performed smoothly.

以上説明したように、本実施形態による詰め替え容器1によれば、フック部21を本容器Aに係止した状態で、詰め替え容器1と本容器Aとを容器軸O方向に沿って相対的に接近移動させるという簡便な作業によって、内容物Nを詰め替えることができる。
しかも、フック部21を本容器Aに係止した後であっても、容器本体2と本容器Aとを容器軸O方向に沿って相対的に接近移動させるまでは、注出口3aは閉塞板4によって閉塞されているので、詰め替え前の段階で容器本体2内の内容物Nがこぼれることがない。
さらに、本容器Aを倒立姿勢にせず、未開封の詰め替え容器1を倒立姿勢にして詰め替え作業を行うので、例えば本容器A内の内容物Nが残留している場合であっても、内容物Nの詰め替え作業を行うことができる。
As described above, according to the refill container 1 according to the present embodiment, the refill container 1 and the main container A are relatively moved along the container axis O direction while the hook portion 21 is locked to the main container A. The contents N can be refilled by a simple operation of moving closer.
Moreover, even after the hook portion 21 is locked to the main container A, the spout 3a remains the closing plate until the main body 2 and the main container A are relatively moved along the container axis O direction. 4, the contents N in the container body 2 are not spilled in the stage before refilling.
Furthermore, since the refilling operation is performed with the unopened refill container 1 in the inverted posture without the main container A being in the inverted posture, for example, even if the content N in the main container A remains, N refilling work can be performed.

そして、保護突片16および突片本体20の一端部20aに形成された係合部30により、閉塞板4に不意に外力が加えられても、保護突片16および突片本体20の一端部20aの相対的な位置がずれることを抑制することが可能になり、閉塞板4が不意の外力によって注出口3aから外れることを抑えることができる。
また、保護突片16および突片本体20の一端部20aに形成された係合部30により、閉塞板4の閉塞状態を維持可能になるとともに、フック部21に連なる突片本体20を注出筒3の本容器Aへの差し込みに伴い引いて係合部30の係合を解除することで、閉塞板4を容易かつ確実に開封可能とし、内容物Nの詰め替え作業を効率よく行うことができる。
Even if an external force is unexpectedly applied to the closing plate 4 by the engaging portion 30 formed at the one end portion 20a of the protective protruding piece 16 and the protruding piece main body 20, one end portions of the protective protruding piece 16 and the protruding piece main body 20 are used. The relative position of 20a can be prevented from shifting, and the closing plate 4 can be prevented from coming off the spout 3a due to an unexpected external force.
Further, the closed state of the closing plate 4 can be maintained by the engaging protrusions 30 formed on the protective protrusion 16 and the one end 20a of the protruding piece body 20, and the protruding piece body 20 connected to the hook portion 21 is poured out. By pulling with the insertion of the tube 3 into the main container A and releasing the engagement of the engaging portion 30, the closing plate 4 can be opened easily and reliably, and the contents N can be refilled efficiently. it can.

また、注出筒3に配設された保護突片16により、例えば、この詰め替え容器1が落下する等したときに、他の物体が、操作突片5ではなく、まず保護突片16に衝突しやすくなり、操作突片5に不意に外力が加えられるのを抑制することが可能になり、意図せず係合部30の係合が解除され注出口3aが開口(開封)されることをより一層抑えることができる。   In addition, when the refill container 1 is dropped, for example, due to the protective projecting piece 16 disposed in the dispensing cylinder 3, another object first collides with the protective projecting piece 16 instead of the operation projecting piece 5. It is possible to prevent an external force from being applied to the operation protrusion 5 unexpectedly, and the engagement portion 30 is unintentionally released and the spout 3a is opened (opened). It can be further suppressed.

また、注出筒3の上方に連設される保護突片16が、注出筒3とともに本容器Aの注入口1A内に差し込み可能になっているので、保護突片16をガイドとして本容器Aの注入口1Aの開口端縁に摺接させながら、詰め替え容器1の注出筒3を本容器Aの注入口1Aに差し込む作業を容易にすることができる。   Moreover, since the protective protrusion 16 continuously provided above the pouring cylinder 3 can be inserted into the inlet 1A of the main container A together with the pouring cylinder 3, the main container can be used with the protective protrusion 16 as a guide. The operation of inserting the dispensing cylinder 3 of the refill container 1 into the injection port 1A of the main container A can be facilitated while being brought into sliding contact with the opening edge of the A injection port 1A.

また、注出筒3内には、容器軸O方向に延びるとともに、内径が前記注出筒3の内径より小さい空気置換筒6が配設され、注出筒3および空気置換筒6は、互いに一体に形成されているため、注出口3aから本容器A内に内容物Nが注出される際に、本容器A内の空気の一部が空気置換筒6を通じて詰め替え容器1内に導入される。このため、本容器A内のエア抜きと詰め替え容器1内の負圧の抑制とを同時に行うことができ、内容物Nの詰め替え作業をよりスムーズに行うことができる。空気置換筒6は注出筒3と平行に配置されるため、注出口部材を容器軸O方向の型割りで一体形成する際に成形金型を複雑にする要因にならず、詰め替え容器1を容易に形成することができる。   Further, an air replacement cylinder 6 that extends in the container axis O direction and has an inner diameter smaller than the inner diameter of the extraction cylinder 3 is disposed in the extraction cylinder 3, and the extraction cylinder 3 and the air replacement cylinder 6 are mutually connected. Since they are integrally formed, when the contents N are poured into the container A from the spout 3a, part of the air in the container A is introduced into the refill container 1 through the air replacement cylinder 6. . For this reason, the air in the main container A and the suppression of the negative pressure in the refill container 1 can be performed simultaneously, and the refilling operation of the contents N can be performed more smoothly. Since the air replacement cylinder 6 is arranged in parallel with the dispensing cylinder 3, it does not become a factor that complicates the molding die when the spout member is integrally formed by dividing the container in the container axis O direction. It can be formed easily.

なお、本発明は上記実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。
例えば、保護突片16は、注出筒3の外周面に沿う単一の円弧状に限らず、係合部30を構成可能であれば、例えば周方向幅を抑えた突出片として設けてもよく、かつ複数設けてもよく、操作突片5の上端部よりも容器軸O方向高さが低くてもよい。
係合部30は、上記実施形態に対して、係止孔等の凹形状と係止爪等の凸形状とを逆にした構成でもよく、かつ互いに離脱可能に係合して閉塞板4を閉塞状態に維持可能な構成であれば凹凸の構成に限らない。さらに、係合部30の係合強さ等を適宜調整することによって、不意な外力に対する閉塞板4のロックに加え、閉塞板4を開く際の切掛とすることが可能である。すなわち、係合部30の係合が解除される際に勢いを付けることによって、閉塞板4を開放しやすくすることができる。
In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, the protective protruding piece 16 is not limited to a single arc shape along the outer peripheral surface of the dispensing cylinder 3, and may be provided as a protruding piece having a reduced circumferential width as long as the engaging portion 30 can be configured. In addition, a plurality of them may be provided, and the height in the container axis O direction may be lower than the upper end portion of the operation protruding piece 5.
The engaging portion 30 may have a configuration in which a concave shape such as a locking hole and a convex shape such as a locking claw are reversed with respect to the above-described embodiment, and the closing plate 4 is detachably engaged with each other. The configuration is not limited to the uneven configuration as long as the configuration can be maintained in the closed state. Furthermore, by appropriately adjusting the engagement strength or the like of the engagement portion 30, it is possible to make a notch when opening the closing plate 4 in addition to locking the closing plate 4 against an unexpected external force. That is, by applying momentum when the engagement of the engaging portion 30 is released, the closing plate 4 can be easily opened.

また、上記実施形態では、注出筒3、閉塞板4及び操作突片5等を含む注出筒部材3Cと、容器本体2と、が互いに別部材とされた構成を示したが、例えば、容器本体2をチューブ容器で構成することなどによって、全てが一体に形成された構成としてもよい。
また、上記実施形態では、フック部21と注出筒3の外周面とをブリッジ部22を介して互いに連結したが、これらを連結しなくてもよい。
また、注出筒3は、平坦壁部42を有さず全周が湾曲壁部41からなる円筒状にしてもよい。
また、容器本体2における口部2a及び胴部2bは、円形状に限らず、例えば、矩形状若しくは楕円形状等、適宜の形状でもよい。
また、上記実施形態では、閉塞板4が容器軸O上に位置し、かつ容器軸Oに直交しているが、例えば、閉塞板4が、容器軸Oを回避した位置に配置されてもよく、かつ閉塞板4が容器軸Oに直交せず傾斜したり湾曲もしくは屈曲してもよい。
Moreover, in the said embodiment, although the extraction cylinder member 3C containing the extraction cylinder 3, the obstruction board 4, and the operation protrusion 5 grade | etc., And the container main body 2 were shown as the mutually separate member, for example, It is good also as a structure by which all were integrally formed, for example by comprising the container main body 2 with a tube container.
Moreover, in the said embodiment, although the hook part 21 and the outer peripheral surface of the extraction | pouring cylinder 3 were mutually connected via the bridge | bridging part 22, these do not need to be connected.
In addition, the dispensing cylinder 3 may have a cylindrical shape that does not have the flat wall portion 42 and has the curved wall portion 41 on the entire circumference.
Further, the mouth portion 2a and the body portion 2b in the container body 2 are not limited to a circular shape, and may be an appropriate shape such as a rectangular shape or an elliptical shape.
