Description

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

従来、例えば下記特許文献１に記載されるような、本容器に詰め替えるための内容物を収容する容器本体と、該容器本体の口部に装着されるとともに該口部を閉塞する中栓と、を備える詰め替え容器が知られている。上記した中栓には、内容物を注出するための注出口が形成されるとともに、この注出口を閉塞するシール部が設けられている。
上記した構成の詰め替え容器では、まずシール部を除去して中栓の注出口を開封し、その後、口部が上方を向く正立姿勢の詰め替え容器の中栓に、倒立姿勢にある本容器の下方を向く口部を螺着し、両容器を互いに連結する。その後、この連結体を上下反転させることにより、本容器を正立姿勢にし、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、詰め替え容器およ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, for example, as described in Patent Document 1 below, a container main body that contains the contents to be refilled in the present container, an inner plug that is attached to the mouth of the container main body and closes the mouth, There are known refillable containers comprising: The above-described inner plug is formed with a spout for pouring out the contents, and a seal portion for closing the spout.
In the refill container having the above-described configuration, first, the sealing portion is removed and the spout of the inner stopper is opened, and then the inside plug of the refill container in the upright position with the mouth portion facing upward is connected to the container in the inverted position. The mouth portion facing downward is screwed to connect the two containers to each other. Thereafter, the container is turned upside down to place the container in an upright position and the refill container in an inverted position. 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である。
また、中栓の注出口を開封した後に本容器の口部を詰め替え容器の中栓に螺着するため、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る。
また、中栓に本容器の口部を螺着する際に本容器を倒立姿勢にするため、本容器の内側に内容物が残留していると本容器内の内容物がこぼれ出る。したがって、本容器内の内容物を完全に使い切った後でないと詰め替え作業を行うことができないという問題がある。 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 is complicated.
Also, since the mouth of the container is screwed into the refill container after opening the spout of the inner plug, if the refill container is accidentally tilted during the screwing operation, the contents in the refill container will spill. There is a risk of getting out.
In addition, when the mouth of the container is screwed onto the inner plug, the container is turned upside down, so that the contents in the container spill out if the contents remain inside the container. Therefore, there is a problem that the refilling work can be performed only after the contents in the container are completely used up.

本発明は、このような事情に鑑みてなされたものであって、詰め替え作業を容易化することができ、かつ、詰め替え時に内容物をこぼしにくく、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を行うことができる詰め替え容器を提供することを目的としている。 The present invention has been made in view of such circumstances, can facilitate refilling work, is difficult to spill contents during refilling, and the contents in the container remain. An object of the present invention is to provide a refill container that can be refilled even if it is present.

上記課題を解決して、このような目的を達成するために、本発明の詰め替え容器は、本容器に詰め替える内容物が収容される容器本体と、該容器本体の口部に装着されるとともに注出口が形成された装着筒、該装着筒に容器軸方向に沿う前記容器本体の外側に向けて延設され前記注出口を径方向の外側から囲む案内壁部、および外周縁が前記注出口の内周面若しくは前記案内壁部の内周面に破断可能な弱化部を介して連結され該注出口を閉塞する閉塞体を有する栓部材と、前記案内壁部の径方向の外側に配置され前記本容器の注入口部に連結される連結筒部、および前記案内壁部の径方向の内側に配置され容器軸方向に延びる押圧筒部を有し、前記案内壁部に前記容器本体の内側に向けてスライド移動可能に装着された操作部材と、を備え、前記栓部材および操作部材にはそれぞれ、該操作部材が前記容器本体の内側に向けてスライド移動したときに、互いが当接して該操作部材のスライド移動を規制するストッパ部が各別に形成され、前記押圧筒部の先端縁は、前記ストッパ部が互いに当接した状態で、前記押圧筒部の先端縁と前記弱化部との間に配設された刃部、または、前記押圧筒部の先端縁に形成された刃部を弱化部より容器軸方向に沿う前記容器本体の内側に位置させる破断部と、該破断部より容器軸方向に沿う前記容器本体の外側に位置し、前記ストッパ部が互いに当接した状態で、前記弱化部から容器軸方向に沿う前記容器本体の外側に離れて位置することにより、前記弱化部を介した前記閉塞体と装着筒若しくは前記案内壁部との連結を維持させる逃げ部と、を備え、前記逃げ部は、前記押圧筒部の先端部における半周を超える部分が除かれるようにして形成され、前記逃げ部および前記破断部の各周端同士は、容器軸方向に沿って延びる接続縁により接続されていることを特徴とする。 In order to solve the above-described problems and achieve such an object, the refill container of the present invention is attached to the container main body in which the contents to be refilled in the present container are stored, and the mouth of the container main body. A mounting cylinder in which an outlet is formed, a guide wall portion extending toward the outer side of the container main body along the container axial direction on the mounting cylinder and surrounding the spout from the radially outer side, and an outer peripheral edge of the spout A plug member that is connected to an inner peripheral surface or an inner peripheral surface of the guide wall portion through a weakened portion that can be broken, and has a closing body that closes the spout, and is disposed on the radially outer side of the guide wall portion. A connecting cylinder connected to the inlet of the container, and a pressing cylinder extending radially inward of the guide wall and extending in the container axial direction; And an operation member mounted so as to be slidable toward the The stopper member and the operation member are each formed with a stopper portion that contacts with each other and regulates the slide movement of the operation member when the operation member slides toward the inside of the container body, The leading edge of the pressing cylinder part is a blade disposed between the leading edge of the pressing cylinder part and the weakening part in a state where the stopper parts are in contact with each other, or the leading edge of the pressing cylinder part A rupture portion for positioning a blade portion formed on an edge inside the container main body along the container axial direction from the weakened portion; and an outer side of the container main body along the container axial direction from the rupture portion; and the stopper portion In a state of being in contact with each other, by being positioned away from the weakened portion to the outside of the container body along the container axial direction, the connection between the closing body and the mounting cylinder or the guide wall portion via the weakened portion is achieved. A clearance section to maintain The relief portion is formed as part of more than half of the tip portion of the pressing tube portion is removed, the peripheral edge between the relief portion and the break portion is connected edges extending along the axial direction of the container It is connected by this.

本発明によれば、本容器に内容物を詰め替える際に、まず、詰め替え容器の連結筒部と本容器の注入口部とを連結し、その後、詰め替え容器の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、詰め替え容器における操作部材を、栓部材および操作部材の各ストッパ部同士が互いに当接するまで、容器本体の内側に向けてスライド移動させることで、押圧筒部により刃部を介して弱化部を押圧して破断させ注出口を開放する。
これにより、詰め替え容器の連結筒部と本容器の注入口部とが連結され、かつ前記各ストッパ部同士が互いに当接した状態で、詰め替え容器の注出口が開放されて、詰め替え容器の容器本体内と本容器内とが注出口および押圧筒部内を通して連通し、容器本体内の内容物が注入口部内に注出されて本容器内に詰め替えられる。
以上のように、詰め替え容器の連結筒部と本容器の注入口部とを連結した後に、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という簡便な操作によって内容物を詰め替えることが可能になり、詰め替え作業を容易化することができる。
また、詰め替えに際し、詰め替え容器の連結筒部と本容器の注入口部とが連結された状態で詰め替え容器の注出口が開放されるので、詰め替え容器の開封と同時に、注出口および押圧筒部内を通して内容物が本容器内に詰め替えられることとなり、内容物がこぼれるのを抑制することができるとともに、本容器を倒立姿勢にすることなく詰め替え作業を行うことが可能になり、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を行うことができる。
また、前述のように詰め替える過程で、前記各ストッパ部同士を互いに当接させておくことにより、本容器および詰め替え容器それぞれの位置や姿勢が不安定になるのを抑制することが可能になり、詰め替え作業を容易化すること、並びに詰め替え時に内容物をこぼし難くすることをより一層確実に実現することができる。
さらに、押圧筒部の先端縁に、前記各ストッパ部同士が互いに当接した状態で、刃部を弱化部より容器軸方向に沿う容器本体の内側に位置させて弱化部を破断させる破断部のみならず、該破断部より容器軸方向に沿う容器本体の外側に位置する逃げ部を備えているので、前記各ストッパ部同士が互いに当接して弱化部が破断部により破断され注出口が開放されたときにも、弱化部のうち、逃げ部と容器軸方向で対向する部分の少なくとも一部は破断させずに、閉塞体と装着筒若しくは案内壁部とを連結したままに維持することが可能になり、閉塞体が装着筒若しくは案内壁部から分離されるのを抑制することができる。 According to the present invention, when refilling the contents of the container, first, the connecting cylinder part of the refill container and the inlet part of the container are connected, and then the container body and the container of the refill container are connected to the container shaft. By moving relatively closer along the direction, the operation member in the refill container is slid toward the inside of the container body until the stopper members of the stopper member and the operation member come into contact with each other, thereby pressing the cylinder portion Thus, the weakened portion is pressed and broken through the blade portion to open the spout.
Thereby, the spout of the refill container is opened while the connecting cylinder part of the refill container and the inlet part of the main container are connected, and the stopper parts are in contact with each other, and the container body of the refill container The inside and the inside of the container communicate with each other through the spout and the pressing cylinder, and the contents in the container body are poured into the inlet and refilled in the container.
As described above, after connecting the connecting tube portion of the refill container and the inlet portion of the main container, the contents are moved by a simple operation of relatively moving the main body and the main container along the axial direction of the container. Can be refilled, and refilling work can be facilitated.
In addition, when refilling, since the spout of the refill container is opened with the connecting cylinder portion of the refill container and the inlet portion of the main container being connected, the refill container is opened simultaneously with the opening of the refill container and the pressure cylinder portion. The contents will be refilled in the container, and it will be possible to prevent the contents from spilling, and it will be possible to carry out refilling work without placing the container in an inverted position. The contents can be refilled even if remains.
In addition, in the process of refilling as described above, it is possible to suppress the position and posture of each of the main container and the refill container from becoming unstable by bringing the stopper portions into contact with each other. It is possible to more surely realize refilling work and make it difficult to spill contents during refilling.
Further, only the rupture portion that breaks the weakened portion by positioning the blade portion on the inner side of the container body along the container axial direction from the weakened portion while the stopper portions are in contact with each other at the distal end edge of the pressing cylinder portion. In addition, since the escape portion located outside the container main body along the container axial direction from the break portion is provided, the stopper portions contact each other, the weakened portion is broken by the break portion, and the spout is opened. In this case, it is possible to keep the closing body and the mounting cylinder or the guide wall portion connected without breaking at least a part of the weakened portion facing the relief portion in the container axial direction. Thus, it is possible to suppress the closure body from being separated from the mounting cylinder or the guide wall portion.

ここで、前記刃部は、前記押圧筒部の破断部に沿って連設された複数の刃を備え、これらの刃の前記弱化部に向けた突出量は、前記破断部の中央に位置する中央刃が最も大きく、かつ該中央刃から外側に離れて位置する刃ほど低くなってもよい。 Here, the blade portion includes a plurality of blades continuously provided along the fracture portion of the pressing cylinder portion, and a protruding amount of the blade toward the weakened portion is located at the center of the fracture portion. The center blade is the largest and may be lowered as the blade is located outward from the center blade.

この場合、前記刃部が備える複数の刃の弱化部に向けた突出量が、前記破断部の中央に位置する中央刃が最も大きく、かつ該中央刃から外側に離れて位置する刃ほど低くなっているので、詰め替え容器における操作部材を前述のように容器本体の内側に向けてスライド移動させる過程で、複数の刃のうち、まず、中央刃が弱化部に当接し、その後、この中央刃より外側に位置する刃が、中央刃に近くかつ突出量が高い刃から順に弱化部に当接することとなる。
したがって、刃部が弱化部に当接した当初に、複数の刃のうち中央刃のみを弱化部に当接させることにより、弱化部に破断の起点が確実に生成されることとなり、その後、この中央刃より外側に位置する刃を、中央刃に近くかつ突出量が高い刃から順に弱化部に当接させて順次破断することにより、弱化部の破断を前述の起点からスムーズに進行させることができる。
以上より、詰め替えに際し、注出口を抵抗少なく容易に開放することができる。 In this case, the amount of protrusion toward the weakened portion of the plurality of blades included in the blade portion is the largest at the center blade located at the center of the fracture portion, and the blade located away from the center blade is lower. Therefore, in the process of sliding the operation member in the refill container toward the inside of the container main body as described above, the center blade first comes into contact with the weakened portion among the plurality of blades. The blade located on the outside comes into contact with the weakened portion in order from the blade close to the center blade and having a high protruding amount.
Therefore, when the blade portion comes into contact with the weakened portion, only the center blade of the plurality of blades is brought into contact with the weakened portion, so that the starting point of breakage is surely generated in the weakened portion. By causing the blade located outside the central blade to contact the weakened portion in order from the blade close to the central blade and having a high protruding amount, the weakened portion can be broken smoothly from the starting point. it can.
From the above, when refilling, the spout can be easily opened with little resistance.

また、前記栓部材に形成された前記ストッパ部は、前記案内壁部から径方向の外側に向けて突出するとともに、前記操作部材に形成された前記ストッパ部は、前記連結筒部から径方向の外側に向けて突出して前記本容器の注入口部の開口端縁上に載置可能とされ、これらの両ストッパ部同士の間には、前記案内壁部に離脱可能に装着され、前記操作部材の前記容器本体の内側に向けたスライド移動を規制する規制部材が配設されてもよい。 The stopper portion formed on the plug member protrudes radially outward from the guide wall portion, and the stopper portion formed on the operation member extends radially from the connecting tube portion. It protrudes toward the outside and can be placed on the opening edge of the inlet portion of the main container. Between the stopper portions, the guide wall portion is detachably mounted, and the operation member A regulating member that regulates the sliding movement toward the inside of the container body may be provided.

この場合、栓部材の案内壁部に規制部材が装着されているので、例えば、流通段階で詰め替え容器に不意に加えられた外力、あるいは、詰め替え容器を倒立姿勢にしたときに作用する容器本体内の内容物の自重等によって、予期せず、操作部材が容器本体の内側に向けてスライド移動して弱化部が破断されてしまうのを防ぐことができる。
また、操作部材に形成されたストッパ部が、本容器の注入口部の開口端縁上に載置可能となっているので、詰め替え容器の連結筒部を本容器の注入口部に連結して内容物を詰め替えるときに、本容器および詰め替え容器それぞれの位置を安定させることができる。
さらに、操作部材に形成されたストッパ部が、連結筒部から径方向の外側に向けて突出し、かつ栓部材に形成されたストッパ部が、案内壁部から径方向の外側に突出するとともに、連結筒部が案内壁部の径方向の外側に配置されているので、操作部材を容器本体の内側に向けてスライド移動させたときに、案内壁部が、連結筒部内（連結筒部と押圧筒部との間）に差し込まれることとなり、本容器および詰め替え容器それぞれの位置をより一層安定させることができる。 In this case, since the regulating member is mounted on the guide wall portion of the stopper member, for example, an external force applied to the refill container unexpectedly at the distribution stage, or the inside of the container body that acts when the refill container is in an inverted posture It is possible to prevent the weakened portion from being broken by unexpectedly sliding the operation member toward the inside of the container body due to its own weight.
Moreover, since the stopper part formed in the operation member can be placed on the opening edge of the inlet part of the container, the connecting cylinder part of the refill container is connected to the inlet part of the container. When refilling the contents, the positions of the main container and the refill container can be stabilized.
Further, the stopper portion formed on the operation member protrudes radially outward from the connecting cylinder portion, and the stopper portion formed on the plug member protrudes radially outward from the guide wall portion and is connected. Since the cylindrical portion is disposed outside the guide wall portion in the radial direction, when the operation member is slid toward the inside of the container main body, the guide wall portion is located in the connecting cylindrical portion (the connecting cylindrical portion and the pressing cylinder). The position of the main container and the refill container can be further stabilized.

本発明によれば、詰め替え作業を容易化することができ、かつ、詰め替え時に内容物をこぼしにくく、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を行うことができる。 According to the present invention, the refilling operation can be facilitated, the contents are hardly spilled during refilling, and the refilling can be performed even when the contents in the container remain. .

栓部材１２は、容器本体１１の口部１１ａに装着されるとともに注出口１４が形成された装着筒１５と、外周縁が注出口１４の内周面に破断可能な弱化部１６を介して連結され該注出口１４を閉塞する閉塞体１７と、装着筒１５に上方（容器軸Ｏ方向に沿う容器本体の外側）に向けて延設され注出口１４を径方向の外側から囲む案内壁部１８と、を備えている。 The plug member 12 is connected to a mounting cylinder 15 mounted on the mouth portion 11a of the container body 11 and formed with a spout 14 via a weakened portion 16 whose outer peripheral edge can be broken on the inner peripheral surface of the spout 14. A closing body 17 that closes the spout 14, and a guide wall 18 that extends upward from the mounting cylinder 15 (outside the container body along the container axis O direction) and surrounds the spout 14 from the outside in the radial direction. And.

装着筒１５は、容器本体１１の口部１１ａに螺着された雌ねじ筒部２１と、雌ねじ筒部２１の径方向の内側に配設され容器本体１１の口部１１ａ内に嵌合されたシール筒部２２と、これらの雌ねじ筒部２１およびシール筒部２２の各上端同士を連結する環状の頂壁（以下、第１ストッパ部という）２３と、を備え、これら２１〜２３は容器軸Ｏと同軸に位置している。シール筒部２２の径方向の内側が注出口１４となっている。
閉塞体１７は円板状に形成されている。
案内壁部１８は、第１ストッパ部２３の内周縁から上方に向けて延設され、容器軸Ｏと同軸に配設された筒状体となっている。案内壁部１８の内径は、注出口１４の内径と同等になっている。
ここで、第１ストッパ部２３は、案内壁部１８から径方向の外側に突出している。また、案内壁部１８の上端部には、径方向の外側に向けて第１係合突部１８ａが全周にわたって突設されている。さらに、案内壁部１８の上端部において第１係合突部１８ａより下方に位置する部分には、径方向の外側に向けて第３係合突部１８ｂが全周にわたって突設されている。なお図示の例では、第１係合突部１８ａの突出量は、第３係合突部１８ｂの突出量より大きくなっている。 The mounting cylinder 15 includes a female threaded cylinder part 21 screwed into the mouth part 11 a of the container main body 11, and a seal that is disposed inside the female threaded cylinder part 21 in the radial direction and is fitted in the mouth part 11 a of the container main body 11. A cylindrical portion 22 and an annular top wall (hereinafter referred to as a first stopper portion) 23 that connects the upper ends of the female screw cylindrical portion 21 and the seal cylindrical portion 22 are provided. And is located coaxially. A radially inner side of the seal cylinder portion 22 is a spout 14.
The closing body 17 is formed in a disk shape.
The guide wall portion 18 is a cylindrical body that extends upward from the inner peripheral edge of the first stopper portion 23 and is disposed coaxially with the container shaft O. The inner diameter of the guide wall 18 is equivalent to the inner diameter of the spout 14.
Here, the first stopper portion 23 protrudes radially outward from the guide wall portion 18. In addition, a first engaging protrusion 18a is provided on the upper end of the guide wall 18 so as to protrude outward in the radial direction. Further, a third engagement protrusion 18b is provided on the entire upper periphery of the guide wall 18 at a portion located below the first engagement protrusion 18a toward the outer side in the radial direction. In the illustrated example, the protruding amount of the first engaging protrusion 18a is larger than the protruding amount of the third engaging protrusion 18b.

操作部材１３は、案内壁部１８の径方向の外側に配置され本容器３の注入口部３ａに連結される連結筒部１９と、案内壁部１８の径方向の内側に配置され容器軸Ｏ方向に延びる押圧筒部２０と、を備え、案内壁部１８に下方に向けてスライド移動可能に装着されている。 The operation member 13 is disposed outside the guide wall 18 in the radial direction and connected to the inlet 3a of the main container 3 and the connecting cylinder 19 is disposed inside the guide wall 18 in the radial direction. A pressing cylinder portion 20 extending in the direction, and is mounted on the guide wall portion 18 so as to be slidable downward.

連結筒部１９は、案内壁部１８に下方に向けてスライド移動可能に外挿された本体筒２５と、本体筒２５の下端部に径方向の外側に向けて突設された環状の第２ストッパ部２７と、を備え、容器軸Ｏと同軸に配設されている。なお、第２ストッパ部２７としては、環状に代えて例えば、周方向に間隔をあけて複数配設された板体を採用してもよい。この場合、周方向で隣り合う板体同士の間隔を空気置換孔として用いてもよい。
本体筒２５の下端部には、径方向の内側に向けて第２係合突部２５ａが全周にわたって突設されている。 The connecting tube portion 19 is externally inserted on the guide wall portion 18 so as to be slidable downward, and a second annular ring projecting radially outward from the lower end portion of the main body tube 25. And a stopper portion 27, which is disposed coaxially with the container axis O. In addition, as the 2nd stopper part 27, it may replace with cyclic | annular form and may employ | adopt the board | plate body arrange | positioned in multiple numbers at intervals in the circumferential direction, for example. In this case, you may use the space | interval of the board bodies adjacent in the circumferential direction as an air replacement hole.
A second engagement protrusion 25a is provided at the lower end of the main body cylinder 25 so as to protrude radially inward.

この第２係合突部２５ａが、案内壁部１８の第１係合突部１８ａに下方から係合することで、操作部材１３の栓部材１２に対する上方に向けたスライド移動が抑えられている。
また、第２係合突部２５ａが、案内壁部１８の第３係合突部１８ｂに上方から係合することで、操作部材１３の栓部材１２に対する下方に向けたスライド移動が規制されていて、後述する規制部材３７が案内壁部１８から離脱された後においても、操作部材１３の容器本体１１側に向けたスライド移動が抑えられる。なお、案内壁部１８に第３係合突部１８ｂを配設するのに代えて、操作部材１３が摺動可能な程度に第２係合突部２５ａが案内壁部１８に単に外嵌するだけでもよい。 The second engagement protrusion 25a engages with the first engagement protrusion 18a of the guide wall 18 from below, so that the upward sliding movement of the operation member 13 relative to the plug member 12 is suppressed. .
Further, the second engagement protrusion 25a engages with the third engagement protrusion 18b of the guide wall 18 from above, so that the downward movement of the operation member 13 relative to the plug member 12 is restricted. Thus, even after the later-described regulating member 37 is detached from the guide wall portion 18, the sliding movement of the operation member 13 toward the container body 11 is suppressed. Instead of disposing the third engagement protrusion 18b on the guide wall 18, the second engagement protrusion 25a is simply fitted on the guide wall 18 to the extent that the operation member 13 can slide. Just be fine.

第２ストッパ部２７は、本容器３の注入口部３ａの開口端縁上に載置可能に形成されるとともに、栓部材１２の第１ストッパ部２３に上方から対向している。これにより、操作部材１３が、栓部材１２に対して下方にスライド移動したときに、第１ストッパ部２３と第２ストッパ部２７とが互いに当接することで、この操作部材１３の下方に向けたこれ以上のスライド移動が規制される。 The second stopper portion 27 is formed so as to be able to be placed on the opening edge of the injection port portion 3a of the container 3, and faces the first stopper portion 23 of the plug member 12 from above. Thereby, when the operation member 13 slides downward with respect to the plug member 12, the first stopper portion 23 and the second stopper portion 27 are in contact with each other, so that the operation member 13 faces downward. Further slide movement is restricted.

本体筒２５の外周面、および第２ストッパ部２７の上面には、これらの各面に沿って一体に延びるガイド板２６が形成されている。ガイド板２６は、連結筒部１９に周方向に間隔をあけて複数、好ましくは周方向に等間隔をあけて複数形成されている。ガイド板２６は、本体筒２５の外周面に形成され、径方向の外側に向けて突出し容器軸Ｏ方向の全長にわたって延びる縦ガイド部２６ａと、第２ストッパ部２７の上面に形成され、縦ガイド部２６ａの下端に連なり径方向の外側に向けて延びる横ガイド部２６ｂと、を備えている。縦ガイド部２６ａの上端部は、下方から上方に向かうに従い漸次、径方向の外側に向けた突出量が小さくなっている。 On the outer peripheral surface of the main body cylinder 25 and the upper surface of the second stopper portion 27, a guide plate 26 extending integrally along these surfaces is formed. A plurality of guide plates 26 are formed in the connecting cylinder portion 19 at intervals in the circumferential direction, preferably at equal intervals in the circumferential direction. The guide plate 26 is formed on the outer peripheral surface of the main body cylinder 25, and is formed on the upper surface of the vertical guide portion 26 a that protrudes outward in the radial direction and extends over the entire length in the container axis O direction, and the second stopper portion 27. And a lateral guide portion 26b that is continuous with the lower end of the portion 26a and extends outward in the radial direction. At the upper end portion of the vertical guide portion 26a, the amount of protrusion toward the radially outer side gradually decreases from the bottom toward the top.

押圧筒部２０は、連結筒部１９の径方向の内側に配設され、案内壁部１８内に下方に向けてスライド移動自在に挿入されている。押圧筒部２０の先端縁は連結筒部１９の下端より下方に突出している。押圧筒部２０の上端部は、連結筒部１９の上端部に容器軸Ｏと同軸に配設された環状の連結板２９を介して連結されている。押圧筒部２０の下方を向く先端縁は、全周にわたって弱化部１６に上方から対向している。 The pressing cylinder portion 20 is disposed inside the connecting cylinder portion 19 in the radial direction, and is inserted into the guide wall portion 18 so as to be slidable downward. The leading edge of the pressing cylinder portion 20 protrudes downward from the lower end of the connecting cylinder portion 19. The upper end portion of the pressing tube portion 20 is connected to the upper end portion of the connecting tube portion 19 via an annular connecting plate 29 disposed coaxially with the container axis O. A tip edge facing downward of the pressing cylinder portion 20 faces the weakened portion 16 from above over the entire circumference.

そして本実施形態では、押圧筒部２０の先端縁が、第１ストッパ部２３と第２ストッパ部２７とが互いに当接した状態で、後述する刃部３２を弱化部１６より下方に位置させる破断部３０と、破断部３０より上方に位置し、第１ストッパ部２３と第２ストッパ部２７とが互いに当接した状態で、弱化部１６を介した閉塞体１７と装着筒１５との連結を維持させる逃げ部２８と、を備えている。

In the state where the first stopper portion 23 and the second stopper portion 27 are in contact with each other, the connection between the closing body 17 and the mounting cylinder 15 is performed via the weakened portion 16. And an escape portion 28 to be maintained.
In the illustrated example, the escape portion 28 is positioned above the weakening portion 16 in a state where the first stopper portion 23 and the second stopper portion 27 are in contact with each other. Further, the escape portion 28 is formed so that a portion exceeding a half circumference in the lower portion of the pressing cylinder portion 20 is removed. The escape portion 28 has a longer circumference than the fracture portion 30. Note that the peripheral ends of the escape portion 28 and the fracture portion 30 are connected to each other by a connection edge 31 extending along the container axis O direction.

ここで本実施形態では、押圧筒部２０の先端縁と弱化部１６との間に刃部３２が配設されている。図示の例では、刃部３２は押圧筒部２０と一体に形成されている。また、刃部３２は、押圧筒部２０の破断部３０に一体に形成されている。
さらに本実施形態では、刃部３２は、押圧筒部２０の破断部３０に沿って連設された複数の刃３３、３４、３５を備えている。これらの刃３３〜３５の下方に向けた突出量Ａ、Ｂ、Ｃは、図２に示されるように、破断部３０の中央に位置する中央刃３３が最も大きく、かつ該中央刃３３から外側に離れて位置する刃ほど低くなっている。すなわち、複数の刃３３〜３５のうち、破断部３０における周方向の外側の端部に位置する刃３５の前記突出高さＣが最も小さく、破断部３０における周方向の中央部に位置する中央刃３３の前記突出高さＡが最も大きく、これらの刃３３、３５同士の間に位置する刃３４の前記突出高さＢが、前記突出高さＡより小さくかつ前記突出高さＣより大きくなっている。なお、刃３３〜３５は、上方から下方に向かうに従い漸次、周方向および径方向の各大きさが双方ともに小さくなっていて下方に向けて尖っている。なお、刃３３〜３５は、その縦断面視において、径方向の内側を向く内面が、上方から下方に向かうに従い漸次、径方向の内側から外側に向けて延在し、径方向の外側を向く外面は、容器軸Ｏ方向に沿って延在している。 Here, in this embodiment, the blade part 32 is arrange | positioned between the front-end edge of the press cylinder part 20, and the weakening part 16. FIG. In the illustrated example, the blade portion 32 is formed integrally with the pressing cylinder portion 20. The blade portion 32 is formed integrally with the fracture portion 30 of the pressing cylinder portion 20.
Further, in the present embodiment, the blade portion 32 includes a plurality of blades 33, 34, and 35 provided continuously along the fracture portion 30 of the pressing cylinder portion 20. As shown in FIG. 2, the protruding amounts A, B, and C directed downward of the blades 33 to 35 are the largest at the central blade 33 located at the center of the fracture portion 30 and are outside the central blade 33. The blade located farther away is lower. That is, among the plurality of blades 33 to 35, the protrusion height C of the blade 35 positioned at the outer end in the circumferential direction of the fracture portion 30 is the smallest, and the center located at the circumferential central portion of the fracture portion 30. The protruding height A of the blade 33 is the largest, and the protruding height B of the blade 34 positioned between the blades 33 and 35 is smaller than the protruding height A and larger than the protruding height C. ing. Note that the blades 33 to 35 are gradually pointed downwardly in the circumferential direction and the radial direction as they move downward from above. The blades 33 to 35 have an inner surface facing the inner side in the radial direction gradually extending from the inner side to the outer side in the radial direction and facing the outer side in the radial direction in the longitudinal sectional view. The outer surface extends along the container axis O direction.

ここで本実施形態では、図１に示されるように、第１ストッパ部２３と第２ストッパ部２７との間に、栓部材１２の案内壁部１８に離脱可能に装着され、操作部材１３の下方に向けたスライド移動を規制する規制部材３７が配設されている。
図示の例では、規制部材３７は、上面視Ｃ字状とされ内部に案内壁部１８が嵌合される弾性変形可能なＣリング部３７ａと、Ｃリング部３７ａにおいて、容器軸Ｏ方向に延びる開口部に対して容器軸Ｏを挟んだ反対側に、径方向の外側に向けて突設されたつまみ板部３７ｂと、を備えている。なお、Ｃリング部３７ａの上端は、案内壁部１８の第３係合突部１８ｂに下方から近接若しくは当接している。 Here, in this embodiment, as shown in FIG. 1, the guide wall portion 18 of the plug member 12 is detachably mounted between the first stopper portion 23 and the second stopper portion 27, and the operation member 13 is A regulating member 37 that regulates the downward sliding movement is disposed.
In the illustrated example, the regulating member 37 has a C-shape when viewed from above, and an elastically deformable C-ring portion 37a into which the guide wall portion 18 is fitted. The C-ring portion 37a extends in the container axis O direction. On the opposite side of the opening with respect to the container shaft O, there is provided a knob plate portion 37b projecting outward in the radial direction. Note that the upper end of the C-ring portion 37a is in close proximity to or in contact with the third engagement protrusion 18b of the guide wall portion 18 from below.

次に、以上のように構成された詰め替え容器１の作用について説明する。 Next, the operation of the refill container 1 configured as described above will be described.

まず、図３に示されるように、操作部材１３における連結筒部１９の本体筒２５を、縦ガイド部２６ａとともに本容器３の注入口部３ａ内に挿入し、かつ連結筒部１９の第２ストッパ部２７を、横ガイド部２６ｂを介して本容器３の注入口部３ａの開口端縁上に載置し、連結筒部１９と本容器３の注入口部３ａとを連結する。また、詰め替え容器１を注出口１４が下方を向く倒立姿勢にし、かつ本容器３を注入口部３ａが上方を向く正立姿勢にする。
以上より、倒立姿勢の詰め替え容器１が、正立姿勢の本容器３の上方に該本容器３と同軸に位置し、また栓部材１２の閉塞体１７が、操作部材１３の押圧筒部２０内を通して本容器３の内部に向けて対向する。 First, as shown in FIG. 3, the main body cylinder 25 of the connection cylinder portion 19 of the operation member 13 is inserted into the inlet 3 a of the main container 3 together with the vertical guide portion 26 a and the second of the connection cylinder portion 19. The stopper portion 27 is placed on the opening edge of the injection port portion 3a of the main container 3 via the lateral guide portion 26b, and the connecting cylinder portion 19 and the injection port portion 3a of the main container 3 are connected. Further, the refill container 1 is set in an inverted posture with the spout 14 facing downward, and the main container 3 is set in an upright posture with the injection port portion 3a facing upward.
As described above, the refill container 1 in the inverted posture is positioned coaxially with the main container 3 above the main container 3 in the upright posture, and the closing member 17 of the plug member 12 is located in the pressing cylinder portion 20 of the operation member 13. It opposes toward the inside of this container 3 through.

この際、詰め替え容器１の注出口１４が閉塞体１７で閉塞されていることから、詰め替え容器１を倒立姿勢としても、容器本体１１内の内容物が注出口１４を通して外部に流出することはない。
また、装着筒１５の第１ストッパ部２３と、操作部材１３の第２ストッパ部２７と、の間に規制部材３７が配設されているので、操作部材１３が容器本体１１側に向けてスライド移動することが規制されていて、弱化部１６が破断されることもない。
さらに、ガイド板２６が連結筒部１９に周方向に間隔をあけて複数形成されているため、連結筒部１９を本容器３の注入口部３ａに安定させて連結することができる。 At this time, since the spout 14 of the refill container 1 is closed by the closing body 17, the contents in the container main body 11 do not flow out through the spout 14 even when the refill container 1 is in an inverted posture. .
Further, since the regulating member 37 is disposed between the first stopper portion 23 of the mounting cylinder 15 and the second stopper portion 27 of the operation member 13, the operation member 13 slides toward the container body 11 side. The movement is restricted, and the weakened portion 16 is not broken.
Further, since a plurality of guide plates 26 are formed in the connecting cylinder portion 19 with a space in the circumferential direction, the connecting cylinder portion 19 can be stably connected to the inlet 3 a of the container 3.

次に、規制部材３７のつまみ板部３７ｂを摘んで、栓部材１２の案内壁部１８に対して径方向の外側に引っ張ることで、図３に示されるように、規制部材３７を案内壁部１８から離脱させる。この際、案内壁部１８の第３係合突部１８ｂが、連結筒部１９の第２係合突部２５ａに容器本体１１側から係合するので、規制部材３７の離脱後直ちに、操作部材１３が容器本体１１側に向けてスライド移動することが抑制されている。
なお、案内壁部１８から規制部材３７を離脱した後に、操作部材１３の連結筒部１９を本容器３の注入口部３ａに連結してもよい。 Next, as shown in FIG. 3, the control member 37 is guided to the guide wall portion by gripping the knob plate portion 37 b of the control member 37 and pulling the control plate 37 radially outward with respect to the guide wall portion 18 of the plug member 12. Remove from 18. At this time, since the third engagement protrusion 18b of the guide wall 18 engages with the second engagement protrusion 25a of the connecting cylinder 19 from the container body 11 side, immediately after the restriction member 37 is detached, the operation member It is suppressed that 13 slides toward the container main body 11 side.
Note that the connecting cylinder portion 19 of the operation member 13 may be connected to the inlet portion 3 a of the container 3 after the regulating member 37 is detached from the guide wall portion 18.

そして、図４に示すように、詰め替え容器１の容器本体１１と本容器３とを容器軸Ｏ方向に沿って相対的に接近移動させ、操作部材１３を、第１ストッパ部２３と第２ストッパ部２７とが互いに当接するまで、容器本体１１の内側に向けてスライド移動させる。
この過程において、案内壁部１８が、押圧筒部２０と連結筒部１９の本体筒２５との間に進入し、かつ押圧筒部２０の先端部分が容器本体１１の口部１１ａ内に進入しながら、押圧筒部２０の破断部３０が、刃部３２を介して弱化部１６を押圧して破断させ、注出口１４が開放される。
このとき、押圧筒部２０は、案内壁部１８に液密に摺接しながら容器本体１１の内側に向けてスライド移動する。 Then, as shown in FIG. 4, the container body 11 and the main container 3 of the refill container 1 are relatively moved along the container axis O direction, and the operation member 13 is moved to the first stopper portion 23 and the second stopper. The container 27 is slid toward the inside of the container body 11 until the parts 27 come into contact with each other.
In this process, the guide wall portion 18 enters between the pressing tube portion 20 and the main body tube 25 of the connecting tube portion 19, and the tip portion of the pressing tube portion 20 enters the mouth portion 11 a of the container body 11. However, the breaking part 30 of the pressing cylinder part 20 presses and weakens the weakened part 16 via the blade part 32, and the spout 14 is opened.
At this time, the pressing cylinder portion 20 slides toward the inside of the container body 11 while being in fluid-tight sliding contact with the guide wall portion 18.

以上より、詰め替え容器１の連結筒部１９と本容器３の注入口部３ａとが連結され、かつ第１ストッパ部２３と第２ストッパ部２７とが互いに当接した状態で、詰め替え容器１の注出口１４が開放されて、詰め替え容器１の容器本体１１内と本容器３内とが注出口１４および押圧筒部２０内を通して連通し、容器本体１１内の内容物が注入口部３ａ内に注出されて本容器３内に詰め替えられる。
ここで、連結筒部１９にガイド板２６が形成されていて、連結筒部１９と、本容器３の注入口部３ａと、の間に、注入口部３ａ内と外部とを連通する隙間が設けられているので、容器本体１１内の内容物を、本容器３の注入口部３ａ内に注入しながら、前記隙間を通して、本容器３内の空気が排出されることとなる。 From the above, in the state where the connecting cylinder part 19 of the refill container 1 and the inlet 3a of the main container 3 are connected and the first stopper part 23 and the second stopper part 27 are in contact with each other, the refill container 1 The spout 14 is opened, and the inside of the container main body 11 of the refill container 1 and the inside of the main container 3 communicate with each other through the spout 14 and the pressing cylinder portion 20, and the contents in the container main body 11 enter the inlet 3 a. It is poured out and refilled in the container 3.
Here, a guide plate 26 is formed in the connecting cylinder part 19, and a gap communicating the inside and outside of the injection port part 3 a is formed between the connecting cylinder part 19 and the injection port part 3 a of the container 3. Since it is provided, the air in the container 3 is discharged through the gap while injecting the contents in the container body 11 into the inlet 3 a of the container 3.

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、連結筒部１９と本容器３の注入口部３ａとを連結した後に、容器本体１１と本容器３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操作によって内容物を詰め替えることが可能になり、詰め替え作業を容易化することができる。
また、詰め替えに際し、詰め替え容器１の連結筒部１９と本容器３の注入口部３ａとが連結された状態で詰め替え容器１の注出口１４が開放されるので、詰め替え容器１の開封と同時に、注出口１４および押圧筒部２０内を通して内容物が本容器３内に詰め替えられることとなり、内容物がこぼれるのを抑制することができるとともに、本容器３を倒立姿勢にすることなく詰め替え作業を行うことが可能になり、本容器３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を行うことができる。 As described above, according to the refill container 1 according to the present embodiment, the container body 11 and the container 3 are moved in the container axis O direction after connecting the connecting cylinder part 19 and the injection port part 3a of the container 3. The contents can be refilled by a simple operation of moving relatively close along, and the refilling operation can be facilitated.
In addition, when refilling, since the spout 14 of the refill container 1 is opened in a state where the connecting cylinder part 19 of the refill container 1 and the injection port part 3a of the main container 3 are connected, simultaneously with opening of the refill container 1, The contents are refilled into the main container 3 through the spout 14 and the pressing cylinder portion 20, so that the contents can be prevented from spilling and the refilling operation is performed without placing the main container 3 in an inverted posture. Thus, even if the contents in the container 3 remain, the contents can be refilled.

また、前述のように詰め替える過程で、第１ストッパ部２３と第２ストッパ部２７とを互いに当接させておくことにより、本容器３および詰め替え容器１それぞれの位置や姿勢が不安定になるのを抑制することが可能になり、詰め替え作業を容易化すること、並びに詰め替え時に内容物をこぼし難くすることをより一層確実に実現することができる。
さらに、押圧筒部２０の先端縁に、第１ストッパ部２３と第２ストッパ部２７とが互いに当接した状態で、刃部３２を弱化部１６より容器本体１１の内側に位置させて弱化部１６を破断させる破断部３０のみならず、破断部３０より容器軸Ｏ方向に沿う容器本体１１の外側に位置する逃げ部２８を備えているので、第１ストッパ部２３と第２ストッパ部２７とが互いに当接して弱化部１６が破断部３０により破断され注出口１４が開放されたときにも、弱化部１６のうち、逃げ部２８と容器軸Ｏ方向で対向する部分の少なくとも一部は破断させずに、閉塞体１７と装着筒１５とを連結したままに維持することが可能になり、閉塞体１７が装着筒１５から分離されるのを抑制することができる。
なお図示の例では、弱化部１６のうち、破断部３０と容器軸Ｏ方向で対向する部分に対して容器軸Ｏを径方向に挟む反対側に位置する部分、言い換えると、逃げ部２８における周方向の中央部に容器軸Ｏ方向で対向する部分が破断されず、閉塞体１７と装着筒１５とが連結されたままに維持される。
また、押圧筒部２０の破断部３０における周方向の外端部によって、図４に示されるように、閉塞体１７を、破断部３０と対応する第１周方向部分が上方に位置し、かつ逃げ部２８と対応する第２周方向部分が下方に位置する傾斜姿勢となるように、該閉塞体１７の第１周方向部分を突き上げた状態に維持することが可能になり、開放された注出口１４が閉塞体１７により閉じられてしまうのを抑制することができる。 Further, in the process of refilling as described above, the positions and postures of the main container 3 and the refill container 1 become unstable by bringing the first stopper portion 23 and the second stopper portion 27 into contact with each other. Therefore, it is possible to more reliably realize refilling work and prevention of spilling the contents during refilling.
Further, with the first stopper portion 23 and the second stopper portion 27 being in contact with each other at the distal end edge of the pressing cylinder portion 20, the blade portion 32 is positioned on the inner side of the container body 11 from the weakening portion 16. 16 includes not only the breaking portion 30 that breaks 16 but also the escape portion 28 located outside the container body 11 along the container axis O direction from the breaking portion 30, so that the first stopper portion 23, the second stopper portion 27, Are in contact with each other and the weakened portion 16 is broken by the broken portion 30 and the spout 14 is opened, at least a portion of the weakened portion 16 facing the escape portion 28 in the container axis O direction is broken. Therefore, it is possible to keep the closing body 17 and the mounting cylinder 15 connected to each other, and it is possible to prevent the closing body 17 from being separated from the mounting cylinder 15.
In the illustrated example, the portion of the weakened portion 16 that is located on the opposite side of the container shaft O in the radial direction with respect to the portion facing the fracture portion 30 in the container axis O direction, in other words, the periphery of the escape portion 28. The portion facing the central portion in the direction in the container axis O direction is not broken, and the closing body 17 and the mounting cylinder 15 are maintained connected.
Further, as shown in FIG. 4, the outer circumferential end of the rupture portion 30 of the pressing cylinder portion 20 causes the closure body 17 to have a first circumferential portion corresponding to the rupture portion 30 positioned above, and It is possible to keep the first circumferential direction portion of the closing body 17 pushed up so that the second circumferential direction portion corresponding to the escape portion 28 has an inclined posture positioned below, and the opened note is released. It is possible to prevent the outlet 14 from being closed by the closing body 17.

また、刃部３２が備える複数の刃３３〜３５の弱化部１６に向けた突出量が、破断部３０の中央に位置する中央刃３３が最も大きく、かつ中央刃３３から外側に離れて位置する刃ほど低くなっているので、詰め替え容器１における操作部材１３を前述のように容器本体１１の内側に向けてスライド移動させる過程で、複数の刃３３〜３５のうち、まず、中央刃３３が弱化部１６に当接し、その後、この中央刃３３より外側に位置する刃３４、３５が、中央刃３３に近くかつ突出量が高い刃から順に弱化部１６に当接することとなる。
したがって、刃部３２が弱化部１６に当接した当初に、複数の刃３３〜３５のうち中央刃３３のみを弱化部１６に当接させることにより、弱化部１６に破断の起点が確実に生成されることとなり、その後、この中央刃３３より外側に位置する刃３４、３５を、中央刃３３に近くかつ突出量が高い刃から順に弱化部１６に当接させて順次破断することにより、弱化部１６の破断を前述の起点からスムーズに進行させることができる。
以上より、詰め替えに際し、注出口１４を抵抗少なく容易に開放することができる。 In addition, the central blade 33 located at the center of the breaking portion 30 has the largest protrusion amount toward the weakened portion 16 of the plurality of blades 33 to 35 included in the blade portion 32, and is positioned away from the central blade 33. Since the height of the blade is lower, in the process of sliding the operation member 13 in the refill container 1 toward the inside of the container body 11 as described above, the central blade 33 is first weakened among the plurality of blades 33 to 35. Then, the blades 34 and 35 located outside the central blade 33 come into contact with the weakened portion 16 in order from the blade close to the central blade 33 and having a high protruding amount.
Therefore, when the blade portion 32 comes into contact with the weakened portion 16, only the central blade 33 among the plurality of blades 33 to 35 is brought into contact with the weakened portion 16, so that a starting point of breakage is reliably generated in the weakened portion 16. After that, the blades 34 and 35 positioned outside the central blade 33 are brought into contact with the weakened portion 16 in order from the blades close to the central blade 33 and having a high protruding amount, thereby being weakened sequentially. The breakage of the portion 16 can proceed smoothly from the above starting point.
From the above, when refilling, the spout 14 can be easily opened with little resistance.

さらに、栓部材１２の案内壁部１８に規制部材３７が装着されているので、例えば、流通段階で詰め替え容器１に不意に加えられた外力、あるいは、詰め替え容器１を倒立姿勢にしたときに作用する容器本体１１内の内容物の自重等によって、予期せず、操作部材１３が容器本体１１の内側に向けてスライド移動して弱化部１６が破断されてしまうのを防ぐことができる。
また、操作部材１３に形成された第２ストッパ部２７が、本容器３の注入口部３ａの開口端縁上に載置可能となっているので、詰め替え容器１の連結筒部１９を本容器３の注入口部３ａに連結して内容物を詰め替えるときに、本容器３および詰め替え容器１それぞれの位置を安定させることができる。
さらに、操作部材１３に形成された第２ストッパ部２７が、連結筒部１９から径方向の外側に向けて突出し、かつ栓部材１２に形成された第１ストッパ部２３が、案内壁部１８から径方向の外側に突出するとともに、連結筒部１９が案内壁部１８の径方向の外側に配置されているので、操作部材１３を容器本体１１の内側に向けてスライド移動させたときに、案内壁部１８が、連結筒部１９内に差し込まれることとなり、本容器３および詰め替え容器１それぞれの位置をより一層安定させることができる。 Further, since the regulating member 37 is mounted on the guide wall portion 18 of the stopper member 12, for example, an external force applied to the refill container 1 unexpectedly at the distribution stage, or an action when the refill container 1 is turned upside down. It is possible to prevent the weakened portion 16 from being broken due to the operation member 13 slidingly moving toward the inside of the container body 11 due to the weight of the contents in the container body 11 to be performed.
Moreover, since the 2nd stopper part 27 formed in the operation member 13 can be mounted on the opening edge of the inlet 3a of this container 3, the connection cylinder part 19 of the refill container 1 is attached to this container. When the contents are refilled by connecting to the three inlet portions 3a, the positions of the main container 3 and the refill container 1 can be stabilized.
Further, the second stopper portion 27 formed on the operation member 13 protrudes radially outward from the connecting tube portion 19, and the first stopper portion 23 formed on the plug member 12 extends from the guide wall portion 18. Since the connecting cylinder portion 19 protrudes outward in the radial direction and is disposed outside the guide wall portion 18 in the radial direction, when the operating member 13 is slid toward the inside of the container body 11, the guide is provided. The wall part 18 will be inserted in the connection cylinder part 19, and the position of this container 3 and the refill container 1 can be stabilized further.

なお、本発明の技術的範囲は前記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

例えば、前記実施形態では、刃部３２が有する複数の刃３３〜３５の前記突出量Ａ〜Ｃを、中央刃３３から外側に離れて位置する刃ほど低くしたが、これに限らず、全て互いに同等にしてもよいし、中央刃３３の前記突出量Ａを、中央刃３３より外側に位置する他の刃３４、３５の前記各突出量Ｂ、Ｃ以下としたり、周方向の一端側から他端側に向かって順次低くなるようにしてもよく、その突出高さの関係は適宜変更してもよい。さらに、刃部が有する刃の数や形状等も前記実施形態に限らず適宜変更してもよい。
また、規制部材３７、ガイド板２６、第１係合突部１８ａ、第３係合突部１８ｂおよび第２係合突部２５ａは設けなくてもよい。
さらに前記実施形態では、閉塞体１７の外周縁を注出口１４の内周面に弱化部１６を介して連結したが、これに代えて、閉塞体１７の外周縁を案内壁部１８の内周面に弱化部１６を介して連結してもよい。 For example, in the said embodiment, although the protrusion amount AC of the some blades 33-35 which the blade part 32 has was made low as the blade located apart from the center blade 33, not only this but all are mutually mutually. The protrusion amount A of the central blade 33 may be equal to or less than the protrusion amounts B and C of the other blades 34 and 35 located outside the central blade 33, or may be different from one end side in the circumferential direction. You may make it become low sequentially toward an end side, and you may change the relationship of the protrusion height suitably. Further, the number and shape of the blades included in the blade portion are not limited to the above embodiment, and may be changed as appropriate.
Further, the regulating member 37, the guide plate 26, the first engagement protrusion 18a, the third engagement protrusion 18b, and the second engagement protrusion 25a may not be provided.
Furthermore, in the said embodiment, although the outer periphery of the obstruction body 17 was connected to the inner peripheral surface of the spout 14 via the weakening part 16, it replaces with this and the outer periphery of the obstruction body 17 is connected to the inner periphery of the guide wall part 18. You may connect to a surface via the weakening part 16. FIG.

また、刃部３２が押圧筒部２０と一体に形成された構成を示したが、図５、図６、図７および図８に示されるように、刃部３８と押圧筒部４１とが互いに別体とされた構成を採用してもよい。
図示の例では、刃部３８は環状に形成され、その下端開口縁に下方に向けて尖る刃３９が全周にわたって複数連設されている。
また、図示の例では、注出口１４を閉塞する閉塞体４０は円板状に形成されるとともに、その外周部に、容器軸Ｏと同軸に上方に向けて装着筒４０ａが突設されている。この装着筒４０ａと案内壁部１８との間に刃部３８が径方向に挟み込まれて配設されている。
案内壁部１８の下端部には、第４係合突部１８ｃが径方向の内側に向けて突設されており、この第４係合突部１８ｃが刃部３８に上方から係合することにより、該刃部３８の上方に向けた移動を規制している。
押圧筒部４１の破断部４２は、周方向の中央から外側に向かうに従い漸次、上方に向い、かつ下方に向けて突の曲線状に形成されている。 Moreover, although the blade part 32 showed the structure formed integrally with the press cylinder part 20, as FIG.5, FIG.6, FIG.7 and FIG. 8 show, the blade part 38 and the press cylinder part 41 mutually. A separate structure may be adopted.
In the example shown in the drawing, the blade portion 38 is formed in an annular shape, and a plurality of blades 39 that are pointed downward at the lower end opening edge are continuously provided over the entire circumference.
Further, in the illustrated example, the closing body 40 that closes the spout 14 is formed in a disc shape, and a mounting cylinder 40 a is provided on the outer periphery of the closing body 40 so as to be coaxial with the container axis O and project upward. . A blade portion 38 is interposed between the mounting cylinder 40a and the guide wall portion 18 in the radial direction.
A fourth engagement protrusion 18c protrudes from the lower end of the guide wall 18 toward the inside in the radial direction, and the fourth engagement protrusion 18c engages the blade 38 from above. Thus, the upward movement of the blade portion 38 is restricted.
The breaking portion 42 of the pressing cylinder portion 41 is formed in a curved shape that gradually protrudes upward and downward from the center in the circumferential direction toward the outside.

以上の構成において、まず図７に示されるように、前記実施形態と同様にして、連結筒部１９と本容器３の注入口部３ａとを連結し、また、詰め替え容器２を注出口１４が下方を向く倒立姿勢にし、かつ本容器３を注入口部３ａが上方を向く正立姿勢にし、さらに、規制部材３７を案内壁部１８から離脱させる。
次に、図８に示されるように、前記実施形態と同様にして、詰め替え容器２の容器本体１１と本容器３とを容器軸Ｏ方向に沿って相対的に接近移動させると、押圧筒部４１の破断部４２が、刃部３８を介して弱化部１６を押圧して破断させ、注出口１４が開放されることにより、容器本体１１内の内容物が注入口部３ａ内に注出されて本容器３内に詰め替えられる。
ここで、押圧筒部４１の破断部４２が、容器本体１１側に向けてスライド移動し、弱化部１６の破断が進行する過程で、閉塞体４０および刃部３８が一体に破断部４２により突き上げられて容器軸Ｏに対して傾くことにより、刃部３８のうち、破断部４２と容器軸Ｏ方向で対向する部分に対して容器軸Ｏを径方向に挟む反対側に位置する部分の外周面、言い換えると、逃げ部４３における周方向の中央部に容器軸Ｏ方向で対向する部分の外周面と、押圧筒部４１の逃げ部４３における周方向の中央部と、の間の隙間が拡げられることとなる。したがって、第１ストッパ部２３と第２ストッパ部２７とが互いに当接した状態で、図８に示されるように、押圧筒部４１の逃げ部４３における周方向の中央部が前記隙間に進入することで、この逃げ部４３が刃部３８に当接することが抑えられる。
以上より、図５、図６、図７および図８に示される詰め替え容器２においても、前記実施形態と同様の作用効果が奏功されることとなる。 In the above configuration, as shown in FIG. 7, first, similarly to the above embodiment, the connecting cylinder portion 19 and the inlet 3 a of the main container 3 are connected, and the refill container 2 is connected to the spout 14. The container 3 is placed in an upright posture facing downward, and the container 3 is placed in an upright posture with the inlet 3 a facing upward, and the regulating member 37 is detached from the guide wall portion 18.
Next, as shown in FIG. 8, when the container body 11 of the refill container 2 and the main container 3 are moved relatively close to each other along the container axis O in the same manner as in the above embodiment, the pressing cylinder portion The rupture portion 42 of 41 presses the weakened portion 16 through the blade portion 38 to break it, and the spout 14 is opened, whereby the contents in the container body 11 are poured out into the inlet portion 3a. Are refilled in the container 3.
Here, in a process in which the breakage portion 42 of the pressing cylinder portion 41 slides toward the container body 11 and the breakage of the weakening portion 16 proceeds, the closing body 40 and the blade portion 38 are integrally pushed up by the breakage portion 42. By being inclined with respect to the container axis O, the outer peripheral surface of the portion of the blade portion 38 located on the opposite side of the container shaft O in the radial direction with respect to the portion facing the fracture portion 42 in the container axis O direction. In other words, the gap between the outer peripheral surface of the portion facing the circumferential central portion of the relief portion 43 in the container axis O direction and the circumferential central portion of the relief portion 43 of the pressing cylinder portion 41 is widened. It will be. Therefore, in the state where the first stopper portion 23 and the second stopper portion 27 are in contact with each other, as shown in FIG. 8, the circumferential central portion of the relief portion 43 of the pressing cylinder portion 41 enters the gap. This prevents the escape portion 43 from coming into contact with the blade portion 38.
From the above, also in the refill container 2 shown in FIGS. 5, 6, 7, and 8, the same effect as that of the above embodiment is achieved.

その他、本発明の趣旨を逸脱しない範囲で、上記した実施の形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上記した変形例を適宜組み合わせてもよい。 In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.

詰め替え作業を容易化することができ、かつ、詰め替え時に内容物をこぼしにくく、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を行うことができる。 The refilling operation can be facilitated, the contents are hardly spilled during refilling, and the refilling can be performed even when the contents in the container remain.
