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。
この詰め替え容器では、まずプルトップを引き上げて、中栓の注出口を開封する。次いで、詰め替え容器を正立姿勢（口部が上向きの姿勢）に配置し、倒立姿勢（口部が下向きの姿勢）とされた本容器の口部を、該詰め替え容器の中栓に螺着する。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, for example, as described in Patent Document 1 below, a container main body in which contents to be refilled in this container are accommodated, and an inner plug that is attached to the mouth of the container main body and closes the mouth, There is known a refill container that performs refilling in a state where an inner plug is screwed into 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 this refill container, the pull top is first pulled up to open the spout of the inner plug. Next, the refill container is placed in an upright position (the mouth is in an upward position), and the mouth of the container in the inverted position (the mouth is in a downward position) is screwed onto the inner plug of the refill container. . 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 in the main container through the insides of the mouths of the refill container and the main container.

しかしながら、上述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 turn the refill container and the main container upside down. The 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、このような事情に鑑みてなされたものであって、詰め替え作業を簡便に行うことができ、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を目的としている。 The present invention has been made in view of such circumstances, and can be easily refilled, the contents are difficult to spill during refilling, and the contents in the container remain. It aims at providing the refill container which can perform refilling work even if it exists.

前記課題を解決するために、本発明は以下の手段を提案している。
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、前記容器本体の口部に装着され、注出口が形成された装着筒と、前記注出口を閉塞するシール部と、前記装着筒に容器軸方向に沿ってスライド移動可能に支持される操作部材と、を備え、前記装着筒には、容器軸方向に直交する径方向に貫通して容器軸方向に延びる溝部が形成され、前記操作部材は、前記装着筒の径方向外側に配設されて本容器に当接される当接筒部と、前記装着筒の径方向内側に配設され、該装着筒に対する操作部材のスライド移動に伴って前記シール部を容器軸方向に押し込み前記注出口を開放させる押し込み筒部と、前記当接筒部と前記押し込み筒部とを連結し、前記溝部内を容器軸方向に沿って移動可能とされた連結部と、を備えたことを特徴とする。 In order to solve the above problems, the present invention proposes the following means.
The refill container of the present invention includes a container main body in which contents to be refilled in the container are accommodated, a mounting cylinder that is attached to the mouth of the container main body and has a spout formed therein, and a seal portion that closes the spout. And an operation member supported by the mounting cylinder so as to be slidable along the container axis direction, and the mounting cylinder has a groove portion extending in the radial direction perpendicular to the container axis direction and extending in the container axis direction. The operation member is formed and disposed on a radially outer side of the mounting cylinder and is in contact with the container, and is disposed on a radially inner side of the mounting cylinder and operates on the mounting cylinder. As the member slides, the seal portion is pushed in the container axial direction to connect the push-in tube portion that opens the spout, the abutting tube portion, and the push-in tube portion, and the groove portion is moved in the container axis direction. A connecting portion that is movable along The features.

本発明に係る詰め替え容器から本容器に内容物を詰め替える際は、まず、操作部材の当接筒部を、本容器の例えば口部（注入口部）の開口端縁に当接させて、詰め替え容器と本容器とを組み合わせる。この状態から、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ることで、装着筒に対して操作部材を注出口側に向けてスライド移動させ、該注出口を閉塞しているシール部を押し込み筒部により押し込むとともに、破断或いは注出口から離脱させ、該注出口を開放させる。
これにより、容器本体の内部が注出口に連通するので、該容器本体内と本容器の注入口部内とが連通し、容器本体内の内容物が、注出口及び注入口部内を通して本容器内に詰め替えられる。 When the contents are refilled from the refill container according to the present invention to the present container, first, the abutting tube portion of the operation member is brought into contact with the opening edge of the mouth portion (injection port portion) of the present container, for example. Combine the container with this container. From this state, by moving the container body of the refill container and the main container relatively close along the container axial direction, the operating member is slid toward the spout side with respect to the mounting cylinder, and the pouring is performed. The seal portion that closes the outlet is pushed in by the push-in cylinder portion, and is broken or separated from the spout to open the spout.
As a result, the inside of the container main body communicates with the spout, so that the inside of the container main body and the inside of the inlet of the main container communicate with each other, and the contents in the container main body enter the main container through the outlet and the inlet. Refilled.

このように、詰め替え容器の当接筒部を本容器の注入口部の開口端縁に当接させた状態としてこれら詰め替え容器及び本容器を組み合わせた後、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作業により、内容物を詰め替えることができるので、詰め替え作業を容易化することができる。 Thus, after combining the refill container and the main container with the contact cylinder part of the refill container in contact with the opening edge of the inlet of the main container, the container body and the main container are moved in the container axial direction. Since the contents can be refilled by a simple work of moving relatively close to each other, the refilling work can be facilitated.

また、詰め替え時、押し込み筒部より径方向外側に配置された当接筒部を、本容器の注入口部の開口端縁に当接させるので、詰め替え容器を安定した姿勢で本容器に組み合わせることができるとともに、装着筒を注入口部内に差し込むことができる。従って、内容物をこぼし難い。
また、上述したように、当接筒部を注入口部の開口端縁に当接させることで操作部材を安定化させることができるので、操作部材を滑らかに移動させることができ、過大な力を必要とせずにシール部を押し込んで注出口を容易に開放させ易い。
さらに、詰め替え容器の開封と同時に内容物を本容器内に詰め替えられるので、本容器を倒立姿勢にすることなく詰め替え作業が行える。よって、本容器内に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。 In addition, when refilling, the abutting cylinder part arranged radially outside the pushing cylinder part is brought into contact with the opening edge of the inlet part of the container, so that the refill container can be combined with the container in a stable posture. In addition, the mounting cylinder can be inserted into the injection port. Therefore, it is difficult to spill the contents.
Further, as described above, since the operating member can be stabilized by bringing the abutting tube portion into contact with the opening edge of the inlet port, the operating member can be smoothly moved, and an excessive force can be obtained. It is easy to open the spout easily by pushing the seal part without needing to be.
Furthermore, since the contents can be refilled into the main container at the same time as the refill container is opened, the refilling operation can be performed without placing the main container in an inverted position. Therefore, even if the contents remain in the container, the contents can be refilled.

また、装着筒と操作部材との間に、該操作部材のスライド移動を規制する規制部材を配置してもよく、この場合には、仮に流通段階等で詰め替え容器に不意に外力が加えられたとしても、操作部材のスライド移動を規制して押し込み筒部がシール部を押し込むことを抑制（防止）でき、詰め替え容器が不意に開封されるのを抑制することができる。
尚、例えば、規制部材が弱化部を介して装着筒及び操作部材の少なくともいずれかに一体的に連結されている場合には、規制部材を別体で設ける場合に比べて部品点数の削減を図ることができ、好ましい。
さらに、注出口をシール部で密封したまま容器本体を倒立状態にして本容器に組み合わせた後、規制部材を除去することで初めて操作部材がスライド移動可能となるため、この詰め替え作業時に内容物がこぼれることを防止できる。 Further, a regulating member that regulates the sliding movement of the operation member may be arranged between the mounting cylinder and the operation member. In this case, external force is unexpectedly applied to the refill container at the distribution stage or the like. Even so, the sliding movement of the operating member can be restricted to suppress (prevent) the pushing cylinder portion from pushing the seal portion, and the refill container can be prevented from being opened unexpectedly.
For example, when the restriction member is integrally connected to at least one of the mounting cylinder and the operation member via the weakening portion, the number of parts is reduced as compared with the case where the restriction member is provided separately. Can be preferred.
Furthermore, after the container body is inverted and combined with this container while the spout is sealed with the sealing portion, the operation member can only be slid by removing the restricting member. Spilling can be prevented.

また、操作部材の当接筒部と押し込み筒部とは、装着筒の溝部内を移動可能な連結部によって連結されており、該連結部によって一体的に移動可能であるので、上述した作用効果を奏しつつも、操作部材の容器軸方向に沿う外形がコンパクトとなる。
また、連結部が溝部内に挿入されていることにより、装着筒に対する操作部材のスライド移動時の姿勢が安定する。 In addition, since the abutting tube portion and the push-in tube portion of the operation member are connected by a connecting portion that can move in the groove portion of the mounting tube, and can be moved integrally by the connecting portion, the above-described operation and effect are achieved. The outer shape along the container axial direction of the operation member is compact while exhibiting the above.
Further, since the connecting portion is inserted into the groove portion, the posture of the operation member when the operating member slides relative to the mounting cylinder is stabilized.

また、本発明の詰め替え容器において、前記装着筒に対する前記操作部材のスライド移動の終端で、前記溝部における前記連結部側を向く内面に、前記連結部が当接されることとしてもよい。 Moreover, the refill container of this invention WHEREIN: The said connection part is good also as abutting on the inner surface which faces the said connection part side in the said groove part at the terminal of the sliding movement of the said operation member with respect to the said mounting cylinder.

この場合、操作部材のスライド移動とともに、該操作部材の連結部が装着筒の溝部の内面に当接されるので、詰め替え時に、これら連結部と溝部の内面との間から内容物が装着筒の径方向外側に漏れ出るようなことが抑制される。 In this case, as the operating member slides, the connecting portion of the operating member comes into contact with the inner surface of the groove portion of the mounting cylinder. Leaking to the outside in the radial direction is suppressed.

また、本発明の詰め替え容器において、前記押し込み筒部の前記シール部に対向する端面には、該端面のうち容器軸回りの一部分が突出するように突起部が形成されていることとしてもよい。 In the refill container of the present invention, a protrusion may be formed on the end surface of the push-in cylinder portion facing the seal portion so that a portion of the end surface around the container axis protrudes.

この場合、押し込み筒部がシール部を押し込む際、該シール部に対して突起部から当接させることができ、これによりシール部が容器軸に対して傾倒するように破断或いは注出口から離脱させられて、注出口を開封しやすい。 In this case, when the push-in cylinder part pushes in the seal part, the seal part can be brought into contact with the seal part from the protrusion, and thereby, the seal part can be broken or detached from the spout so as to be inclined with respect to the container shaft. It is easy to open the spout.

また、本発明の詰め替え容器において、前記突起部の径方向内側を向く内面には、容器軸方向に延びるリブ及び溝の少なくともいずれかが形成されていることとしてもよい。 In the refill container of the present invention, at least one of a rib and a groove extending in the container axial direction may be formed on the inner surface of the protrusion that faces the radially inner side.

この場合、押し込み筒部がシール部を押し込んで注出口が開封（開放）された際に、内容物の液面に突起部のリブや溝を突き当て、該液面に作用する表面張力のバランスを崩して不均衡にすることによって、容器本体内の内容物と、本容器内の空気との置換を開始させるきっかけとすることが可能になる。従って、たとえ内容物の粘度が高いような場合であっても、容器本体の内容物を注出口に詰まらせることなく、確実に本容器に詰め替えることができる。 In this case, when the push-in cylinder part pushes in the seal part and the spout is opened (opened), the ribs and grooves of the protrusions abut against the liquid level of the contents, and the balance of the surface tension acting on the liquid level It is possible to start the replacement of the contents in the container main body with the air in the container by breaking the balance. Therefore, even if the viscosity of the contents is high, the contents of the container body can be reliably refilled into the container without clogging the outlet.

また、本発明の詰め替え容器において、前記突起部における前記シール部側の先端部の容器軸回りに沿う長さが、前記シール部とは反対側の基端部の前記長さより小さくなっていることとしてもよい。 Further, in the refill container of the present invention, the length of the protruding portion along the container axis of the tip portion on the seal portion side is smaller than the length of the base end portion on the side opposite to the seal portion. It is good.

この場合、突起部が、シール部側へ向けて先鋭（先細）形状となるので、押し込み筒部がシール部を押し込んで注出口が開封された際に、内容物の液面に突起部の先端部を突き刺して、内容物を、容器軸回りに沿って突起部の外側に拡げながら基端部側に向けて導入しやすくなる。 In this case, since the protruding portion has a sharp (tapered) shape toward the seal portion side, when the pushing cylinder portion pushes the seal portion and the spout is opened, the tip of the protruding portion is brought into the liquid level of the contents. It becomes easy to introduce the contents toward the base end side while expanding the outside of the protruding portion along the circumference of the container axis.

本発明に係る詰め替え容器によれば、詰め替え作業を簡便に行うことができ、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 refill container according to the present invention, the refilling operation can be easily performed, and it is difficult to spill the contents at the time of refilling, and the refilling operation is performed even when the contents in the container remain. Can do.

The pushing cylinder portion 13 is disposed in the vicinity of the center in the container axis O direction in the dispensing cylinder 10. An end surface (lower end surface) facing downward in the push-in cylinder portion 13 is disposed opposite to the upper end surface of the peripheral wall 5 b of the seal portion 5. A protruding portion 13 a is formed on the lower end surface of the push-in cylinder portion 13 so that a part of the lower end surface along the circumferential direction protrudes.
In the bottom view of the operation member 6 shown in FIG. 2, the protrusion 13a is formed in an arc shape.

本実施形態では、連結部１４は、円弧板状をなしており、図１に示されるように、当接筒部１２における容器軸Ｏ方向の中央部と、押し込み筒部１３の上端開口部とを径方向に連結している。連結部１４の周方向に沿う長さは、装着筒４の溝部１１の周方向に沿う長さに対応しているとともに、連結部１４において周方向を向く側面は、溝部１１の内面１１ｂに摺動自在となっている。また、連結部１４は、溝部１１内における容器軸Ｏ方向に沿う一対の係止リブ１１ｃ同士の間に配設されている。
連結部１４の下面は、円弧状の平面となっている。そして、装着筒４に対する操作部材６のスライド移動の終端（下方移動端）で、溝部１１における連結部１４側を向く内面１１ａ（容器軸Ｏ方向で対向する面）に、該連結部１４の下面が当接されるようになっている。 In the present embodiment, the connecting portion 14 has an arc plate shape, and as shown in FIG. 1, the central portion of the abutting tube portion 12 in the container axis O direction, and the upper end opening of the push-in tube portion 13. Are connected in the radial direction. The length along the circumferential direction of the connecting portion 14 corresponds to the length along the circumferential direction of the groove portion 11 of the mounting cylinder 4, and the side surface of the connecting portion 14 facing the circumferential direction slides on the inner surface 11 b of the groove portion 11. It is free to move. Further, the connecting portion 14 is disposed between the pair of locking ribs 11 c along the container axis O direction in the groove portion 11.
The lower surface of the connecting portion 14 is an arc-shaped plane. Then, at the end of sliding movement of the operating member 6 with respect to the mounting cylinder 4 (downward moving end), the inner surface 11a (surface facing in the container axis O direction) of the groove portion 11 facing the connecting portion 14 side is placed on the lower surface of the connecting portion 14. Are in contact with each other.

規制部材７は、装着筒４の注出筒１０に径方向の外側から着脱可能に装着されるリング部７ａと、リング部７ａの外周面から径方向外側に向けて突出する操作突起７ｂと、を備えている。 The restricting member 7 includes a ring portion 7a that is detachably attached to the dispensing tube 10 of the attachment tube 4 from the outside in the radial direction, an operation protrusion 7b that protrudes radially outward from the outer peripheral surface of the ring portion 7a, It has.

リング部７ａは、容器軸Ｏに直交する断面がＣ字状をなしており、弾性変形することで注出筒１０から離脱可能となっている。図１において、リング部７ａの上端面は、当接筒部１２の下端面に当接しており、リング部７ａの下端面は、基筒８の天壁８ａの上面に当接している。リング部７ａは、操作部材６の当接筒部１２と基筒８の天壁８ａとに容器軸Ｏ方向から挟まれており、これにより、装着筒４に対する操作部材６の下方移動（スライド移動）が規制されている。 The ring portion 7a has a C-shaped cross section orthogonal to the container axis O, and can be detached from the dispensing cylinder 10 by elastic deformation. In FIG. 1, the upper end surface of the ring portion 7 a is in contact with the lower end surface of the contact tube portion 12, and the lower end surface of the ring portion 7 a is in contact with the upper surface of the top wall 8 a of the base tube 8. The ring portion 7a is sandwiched between the contact tube portion 12 of the operation member 6 and the top wall 8a of the base tube 8 from the container axis O direction, whereby the operation member 6 is moved downward (sliding) with respect to the mounting tube 4. ) Is regulated.

操作突起７ｂは、リング部７ａの周方向の一部分から径方向外側に向けて突出するとともに、容器軸Ｏ方向に沿って延びる板状に形成されている。本実施形態では、操作突起７ｂが矩形板状をなしており、その上側部分がリング部７ａの上端面より上側に突出している。図示の例では、操作突起７ｂの上端面は、当接筒部１２のフランジ１２ａの下面に当接し、操作突起７ｂの下端面は、基筒８の天壁８ａの上面に当接しており、かつ、リング部７ａの上端面が当接筒部１２の下端面に当接し、リング部７ａの下端面が基筒８の天壁８ａの上面に当接しているが、操作突起７ｂおよびリング部７ａの少なくとも一方が、上記構成によって操作部材６の下方移動を規制すればよい。 The operation protrusion 7b is formed in a plate shape that protrudes radially outward from a part of the ring portion 7a in the circumferential direction and extends along the container axis O direction. In the present embodiment, the operation projection 7b has a rectangular plate shape, and the upper portion thereof protrudes upward from the upper end surface of the ring portion 7a. In the illustrated example, the upper end surface of the operation projection 7b is in contact with the lower surface of the flange 12a of the contact cylinder portion 12, and the lower end surface of the operation projection 7b is in contact with the upper surface of the top wall 8a of the base tube 8, In addition, the upper end surface of the ring portion 7a is in contact with the lower end surface of the contact tube portion 12, and the lower end surface of the ring portion 7a is in contact with the upper surface of the top wall 8a of the base tube 8. It suffices that at least one of 7a regulates the downward movement of the operation member 6 by the above configuration.

尚、前述した規制部材７の代わりに、例えば、リング状とされた規制部材７が、容易に破断可能とされた弱化部を介して、装着筒４及び操作部材６の少なくともいずれかに一体的に連結されていてもよい。 Instead of the restriction member 7 described above, for example, the ring-like restriction member 7 is integrated with at least one of the mounting cylinder 4 and the operation member 6 via a weakened portion that can be easily broken. It may be connected to.

次に、詰め替え容器１から本容器３０に内容物を詰め替える手順について、図３及び図４を参照して説明する。
まず、詰め替え容器１を倒立姿勢にするとともに、本容器３０を正立姿勢にした状態で、これら詰め替え容器１の口部２ａと本容器３０の口部（注入口部）３１とを対向配置する。詰め替え容器１と本容器３０とを、互いの容器軸Ｏが同軸となるように位置合わせしつつ、相対的に容器軸Ｏ方向に接近移動させ、図３に示されるように、操作部材６の当接筒部１２のフランジ１２ａを、本容器３０の注入口部３１の開口端縁に当接させて、詰め替え容器１と本容器３０とを組み合わせる。この際、操作部材６の当接筒部１２が、本容器３０の注入口部３１内に差し込まれた状態で詰め替え容器１と本容器３０とが組み合わされる。 Next, a procedure for refilling the contents from the refill container 1 into the main container 30 will be described with reference to FIGS. 3 and 4.
First, the refill container 1 is set in an inverted posture, and the mouth portion 2a of the refill container 1 and the mouth portion (injection port portion) 31 of the refill container 30 are opposed to each other with the main container 30 in the upright posture. . The refill container 1 and the main container 30 are moved closer to each other in the direction of the container axis O while aligning them so that the container axes O are coaxial with each other, and as shown in FIG. The refill container 1 and the main container 30 are combined by bringing the flange 12 a of the abutting cylinder part 12 into contact with the opening edge of the inlet 31 of the main container 30. At this time, the refill container 1 and the main container 30 are combined in a state in which the abutting cylinder part 12 of the operation member 6 is inserted into the injection port part 31 of the main container 30.

ここで本実施形態では、上述したように詰め替え容器１を倒立姿勢とすることで、詰め替え容器１における上下が反転することとなり、倒立姿勢の詰め替え容器１において、容器軸Ｏ方向に沿った操作部材６側が下側、容器本体２側が上側となる。
尚、詰め替え容器１の注出口３がシール部５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２内の内容物が注出口３を通して外部に流出することはない。さらに、装着筒４と操作部材６との間に規制部材７が配置され、操作部材６の連結部１４が係止リブ１１ｃによって支持されているため、操作部材６のスライド移動は規制されている。また、シール部５の底壁５ａの外周縁部が、基筒８の天壁８ａの下面に当接しているため、内容物の重量によってシール部５が開放されてしまうことが防止されている。 Here, in the present embodiment, as described above, the refill container 1 is turned upside down, so that the top and bottom of the refill container 1 are inverted, and the operation member along the container axis O direction in the refill container 1 in the inverted position. The 6 side is the lower side, and the container body 2 side is the upper side.
In addition, since the spout 3 of the refill container 1 is closed by the seal portion 5, the contents in the container main body 2 do not flow out to the outside through the spout 3 even when the refill container 1 is in an inverted posture. Furthermore, since the regulating member 7 is disposed between the mounting cylinder 4 and the operation member 6 and the connecting portion 14 of the operation member 6 is supported by the locking rib 11c, the sliding movement of the operation member 6 is regulated. . Further, since the outer peripheral edge portion of the bottom wall 5a of the seal portion 5 is in contact with the lower surface of the top wall 8a of the base tube 8, the seal portion 5 is prevented from being opened due to the weight of the contents. .

この状態で、詰め替え容器１から規制部材７を分離する。具体的には、規制部材７の操作突起７ｂを把持し径方向の外側に向けて引っ張ることにより、該操作突起７ｂとともにリング部７ａが径方向外側に引っ張られ、リング部７ａが弾性変形して注出筒１０から離脱される。この際、注出筒１０に対して径方向へ向けた外力が加えられた場合であっても、本容器３０の注入口部３１内に詰め替え容器１の当接筒部１２が挿入されていることにより、詰め替え容器１と本容器３０との連結が解除されるようなことが防止されている。 In this state, the regulating member 7 is separated from the refill container 1. Specifically, when the operating projection 7b of the regulating member 7 is gripped and pulled outward in the radial direction, the ring portion 7a is pulled outward in the radial direction together with the operating projection 7b, and the ring portion 7a is elastically deformed. It is removed from the dispensing tube 10. At this time, even when an external force in the radial direction is applied to the dispensing cylinder 10, the contact cylinder portion 12 of the refill container 1 is inserted into the inlet 31 of the main container 30. This prevents the connection between the refill container 1 and the main container 30 from being released.

このように、規制部材７が詰め替え容器１から分離されて、装着筒４と操作部材６との容器軸Ｏ方向の接近移動に対する規制が解除される。尚、詰め替え容器１から規制部材７を分離した後、詰め替え容器１を倒立姿勢にするとともに、本容器３０を正立姿勢にした状態で、詰め替え容器１の当接筒部１２と本容器３０の注入口部３１とを連結させてもよい。
また、本実施形態では、詰め替え容器１から規制部材７を取り外した図３の状態において、操作部材６の連結部１４が溝部１１の係止リブ１１ｃに当接するようになっており、該連結部１４が係止リブ１１ｃを乗り越えない限り、装着筒４に対して操作部材６がスライド移動を開始するようなことが防止されている。 In this way, the restriction member 7 is separated from the refill container 1 and the restriction on the close movement of the mounting cylinder 4 and the operation member 6 in the container axis O direction is released. In addition, after separating the regulating member 7 from the refill container 1, the refill container 1 is turned upside down, and the main container 30 is placed in the upright position, and the contact cylinder portion 12 of the refill container 1 and the main container 30 are The inlet 31 may be connected.
Moreover, in this embodiment, in the state of FIG. 3 where the regulating member 7 is removed from the refill container 1, the connecting portion 14 of the operation member 6 comes into contact with the locking rib 11c of the groove portion 11, and the connecting portion As long as 14 does not get over the locking rib 11c, the operation member 6 is prevented from starting to slide relative to the mounting cylinder 4.

そして、図４に示されるように、詰め替え容器１の容器本体２と本容器３０とを容器軸Ｏ方向に沿って相対的に接近移動させると、本容器３０の注入口部３１の開口端縁が当接筒部１２のフランジ１２ａを注出口３側に向けて押し込むとともに、連結部１４が溝部１１の係止リブ１１ｃを乗り越え、装着筒４に対して操作部材６が注出口３側に向けてスライド移動させられる。すると、操作部材６の押し込み筒部１３が、シール部５を押圧して注出口３から離脱させ、該注出口３を開放させる。この際、装着筒４における注出筒１０の溝部１１は、その略全体が本容器３０の注入口部３１内に挿入される。 As shown in FIG. 4, when the container body 2 of the refill container 1 and the main container 30 are relatively moved along the container axis O direction, the opening edge of the inlet portion 31 of the main container 30. Pushes the flange 12a of the abutting tube portion 12 toward the spout 3 side, the connecting portion 14 gets over the locking rib 11c of the groove portion 11, and the operating member 6 faces the spout 3 side with respect to the mounting tube 4. And slide it. Then, the push-in cylinder part 13 of the operation member 6 presses the seal part 5 to disengage from the spout 3 and opens the spout 3. At this time, substantially the entire groove portion 11 of the dispensing tube 10 in the mounting tube 4 is inserted into the inlet 31 of the container 30.

これにより、注出口３、押し込み筒部１３及び注出筒１０を通して、詰め替え容器１の容器本体２内と本容器３０の注入口部３１内とが連通する。よって、詰め替え容器１の容器本体２内に収容されている内容物を、本容器３０の注入口部３１内に注出することができ、内容物を詰め替え容器１から本容器３０に詰め替えることができる。
尚、詰め替え作業中、当接筒部１２の空気置換溝１２ｂ内を通して、本容器３０の内部及び詰め替え容器１の容器本体２の内部と、これら容器の外部との空気置換を効率よく行うことができるようになっているとともに、本容器３０内にスムーズに内容物を注出して、詰め替え作業を効率良く行うことができる。 Thereby, the inside of the container main body 2 of the refill container 1 and the inside of the inlet 31 of the main container 30 communicate with each other through the spout 3, the push-in cylinder 13 and the extraction cylinder 10. Therefore, the contents accommodated in the container body 2 of the refill container 1 can be poured into the inlet 31 of the main container 30, and the contents can be refilled from the refill container 1 to the main container 30. it can.
In addition, during the refilling operation, the air replacement between the inside of the main container 30 and the inside of the container main body 2 of the refilling container 1 and the outside of the container can be efficiently performed through the air replacement groove 12b of the abutting cylinder portion 12. In addition, the contents can be smoothly poured into the container 30 and the refilling operation can be performed efficiently.

以上説明したように、本実施形態の詰め替え容器１によれば、当接筒部１２を本容器３０の注入口部３１の開口端縁に当接させた状態としてこれら詰め替え容器１及び本容器３０を組み合わせた後、容器本体２と本容器３０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り、内容物を詰め替えることができるので、詰め替え作業を容易化することができる。 As described above, according to the refill container 1 of the present embodiment, the refill container 1 and the main container 30 are in a state in which the abutting cylinder portion 12 is in contact with the opening edge of the inlet 31 of the main container 30. After the combination, the contents can be refilled by a simple operation of relatively moving the container body 2 and the main container 30 along the container axis O direction, thereby facilitating the refilling work. it can.

また、詰め替え時、押し込み筒部１３より径方向外側に配置された当接筒部１２のフランジ１２ａを、本容器３０の注入口部３１の開口端縁に当接させるので、詰め替え容器１を安定した姿勢で本容器３０に組み合わせることができるとともに、装着筒４の注出筒１０を注入口部３１内に差し込むことができる。従って、内容物をこぼし難い。
また、上述したように、当接筒部１２のフランジ１２ａを注入口部３１の開口端縁に当接させることで操作部材６を安定化させることができるので、操作部材６を滑らかに移動させることができ、過大な力を必要とせずにシール部５を押し込んで注出口３を容易に開放させ易い。
さらに、詰め替え容器１の開封と同時に内容物を本容器３０内に詰め替えられるので、本容器３０を倒立姿勢にすることなく詰め替え作業が行える。よって、本容器３０内に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。 Moreover, since the flange 12a of the contact cylinder part 12 arrange | positioned in the radial direction outer side from the pushing cylinder part 13 is contact | abutted at the opening edge of the inlet part 31 of this container 30 at the time of refilling, the refill container 1 is stabilized. In this manner, the container 30 can be combined with the container 30, and the dispensing tube 10 of the mounting tube 4 can be inserted into the inlet 31. Therefore, it is difficult to spill the contents.
Moreover, since the operation member 6 can be stabilized by making the flange 12a of the contact cylinder part 12 contact | abut to the opening edge of the injection port part 31 as mentioned above, the operation member 6 is moved smoothly. It is possible to easily open the spout 3 by pushing the seal portion 5 without requiring an excessive force.
Furthermore, since the contents can be refilled into the main container 30 simultaneously with the opening of the refill container 1, the refilling operation can be performed without placing the main container 30 in an inverted posture. Therefore, even if the contents remain in the container 30, the contents can be refilled.

また、装着筒４と操作部材６との間に、該操作部材６のスライド移動を規制する規制部材７が配置されているので、仮に製品の流通段階等で詰め替え容器１に不意に外力が加えられたとしても、操作部材６のスライド移動を規制して押し込み筒部１３がシール部５を押し込むことを抑制（防止）でき、詰め替え容器１が不意に開封されるのを抑制することができる。
尚、規制部材７が、弱化部を介して装着筒４及び操作部材６の少なくともいずれかに一体的に連結されている場合には、規制部材７を別体で設ける場合に比べて部品点数の削減を図ることができ、好ましい。
さらに、注出口３をシール部５で密封したまま容器本体２を倒立状態にして本容器３０に組み合わせた後、規制部材７を除去することで初めて操作部材６がスライド移動可能となるため、この詰め替え作業時に内容物がこぼれることを防止できる。 In addition, since a regulating member 7 that regulates the sliding movement of the operation member 6 is disposed between the mounting cylinder 4 and the operation member 6, an external force is applied to the refill container 1 unexpectedly at the product distribution stage or the like. Even if it is done, the sliding movement of the operating member 6 can be restricted to prevent (push) the pushing cylinder part 13 from pushing in the seal part 5, and the refill container 1 can be prevented from being opened unexpectedly.
In addition, when the regulating member 7 is integrally connected to at least one of the mounting cylinder 4 and the operating member 6 via the weakened portion, the number of parts is smaller than when the regulating member 7 is provided separately. Reduction can be achieved, which is preferable.
Furthermore, since the container body 2 is turned upside down with the spout 3 sealed with the seal portion 5 and combined with the container 30, the operation member 6 becomes slidable only after the restriction member 7 is removed. The contents can be prevented from spilling during refilling work.

また、操作部材６の当接筒部１２と押し込み筒部１３とは、装着筒４の溝部１１内を移動可能な連結部１４によって連結されており、該連結部１４によって一体的に移動可能であるので、上述した作用効果を奏しつつも、操作部材６の容器軸Ｏ方向に沿う外形がコンパクトとなる。
また、連結部１４が溝部１１内に挿入されていることにより、装着筒４に対する操作部材６のスライド移動時の姿勢が安定する。 Further, the abutting cylinder portion 12 and the push-in cylinder portion 13 of the operation member 6 are connected by a connecting portion 14 that is movable in the groove portion 11 of the mounting cylinder 4, and can be moved integrally by the connecting portion 14. Therefore, the outer shape of the operation member 6 along the container axis O direction is compact while achieving the above-described effects.
Further, since the connecting portion 14 is inserted into the groove portion 11, the posture of the operating member 6 relative to the mounting cylinder 4 during the sliding movement is stabilized.

また、図４に示されるように、装着筒４に対する操作部材６のスライド移動の終端（装着筒４に対する操作部材６の前進端位置）で、溝部１１における連結部１４側を向く内面１１ａに、該連結部１４が当接されるようになっているので、下記の効果を奏する。
すなわち、操作部材６のスライド移動とともに、該操作部材６の連結部１４が装着筒４の溝部１１の内面１１ａに当接されるので、詰め替え時に、これら連結部１４と溝部１１の内面１１ａとの間から内容物が注出筒１０の径方向外側に漏れ出るようなことが抑制される。
特に、本実施形態においては、連結部１４において周方向を向く側面と、溝部１１の内面１１ｂとが摺動自在に当接されており、かつ、当接筒部１２の内周面と、注出筒１０の外周面とが摺動自在に当接されているから、前述の効果がより確実に得られやすい。
尚、押し込み筒部１３がシール部５に当接した時点で、当接筒部１２が溝部１１を覆うように構成されていることが好ましい。具体的には、図３において、当接筒部１２の天壁８ａ側の端面（下端開口縁）と、溝部１１の連結部１４側を向く内面１１ａとの間の距離が、押し込み筒部１３の突起部１３ａにおいてシール部５側を向く端面と、シール部５の周壁５ｂにおいて押し込み筒部１３側を向く端面との間の距離に対して、同等以下となっていることが好ましい。
図４に示される例では、連結部１４が溝部１１の内面１１ａに当接した状態において、当接筒部１２の容器本体２側を向く端面が基筒８の天壁８ａに当接しているが、これに限定されるものではない。すなわち、連結部１４と内面１１ａとが当接した状態において、当接筒部１２の前記端面と天壁８ａとの間に隙間が形成されていても構わない。 Further, as shown in FIG. 4, at the end of the sliding movement of the operation member 6 with respect to the mounting cylinder 4 (advance end position of the operation member 6 with respect to the mounting cylinder 4), on the inner surface 11 a facing the connecting portion 14 side in the groove portion 11, Since the connecting portion 14 is brought into contact, the following effects are obtained.
That is, as the operating member 6 slides, the connecting portion 14 of the operating member 6 comes into contact with the inner surface 11a of the groove portion 11 of the mounting cylinder 4, and therefore, when refilling, the connecting portion 14 and the inner surface 11a of the groove portion 11 It is suppressed that the content leaks out to the radial direction outer side of the pouring cylinder 10 from between.
In particular, in the present embodiment, the side surface facing the circumferential direction in the connecting portion 14 and the inner surface 11b of the groove portion 11 are slidably contacted, and the inner peripheral surface of the contact cylindrical portion 12 Since the outer peripheral surface of the outlet tube 10 is slidably contacted, the above-described effect can be more easily obtained.
In addition, it is preferable that the contact cylinder part 12 is configured to cover the groove part 11 when the push-in cylinder part 13 contacts the seal part 5. Specifically, in FIG. 3, the distance between the end surface (lower end opening edge) of the abutting tube portion 12 on the top wall 8 a side and the inner surface 11 a facing the connecting portion 14 side of the groove portion 11 is the pushing tube portion 13. It is preferable that the distance between the end surface of the protrusion 13a facing the seal portion 5 side and the end surface of the peripheral wall 5b of the seal portion 5 facing the push-in cylinder portion 13 is equal or less.
In the example shown in FIG. 4, the end surface of the abutting tube portion 12 facing the container body 2 is in contact with the top wall 8 a of the base tube 8 in a state where the connecting portion 14 is in contact with the inner surface 11 a of the groove portion 11. However, the present invention is not limited to this. That is, a gap may be formed between the end surface of the abutting tube portion 12 and the top wall 8a in a state where the connecting portion 14 and the inner surface 11a are in contact with each other.

また、押し込み筒部１３におけるシール部５に対向する端面に、該端面から突出して突起部１３ａが形成されているので、押し込み筒部１３がシール部５を押し込む際、該シール部５に対して突起部１３ａから当接させることができ、これによりシール部５が容器軸Ｏに対して傾倒するように注出口３から離脱させられて、注出口３を開封しやすい（図４参照）。 Further, since the protruding portion 13a is formed on the end surface of the push-in cylinder portion 13 facing the seal portion 5 so as to protrude from the end surface, when the push-in tube portion 13 pushes in the seal portion 5, the seal portion 5 It can be made to contact | abut from the projection part 13a, and it is made to detach | leave from the spout 3 so that the seal part 5 may incline with respect to the container axis | shaft O, and it is easy to open the spout 3 (refer FIG. 4).

尚、本発明は前述の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 present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

例えば、前述の実施形態では、装着筒４における注出筒１０の周方向に沿う一部分が切り欠かれるように溝部１１が形成され、これに対応して、操作部材６の連結部１４も周方向に１つ形成されている例を用いて説明したが、これに限定されるものではない。すなわち、溝部１１は、注出筒１０の周方向に間隔をあけて複数形成されていてもよく、これに対応して、連結部１４も周方向に間隔をあけて複数形成されていてもよい。この場合、操作部材６の剛性が高められ、該操作部材のスライド移動がより安定する。 For example, in the above-described embodiment, the groove portion 11 is formed so that a portion along the circumferential direction of the dispensing cylinder 10 in the mounting cylinder 4 is cut out, and the connecting portion 14 of the operation member 6 is also circumferentially corresponding to this. However, the present invention is not limited to this example. That is, a plurality of groove portions 11 may be formed at intervals in the circumferential direction of the dispensing tube 10, and a plurality of connection portions 14 may be formed at intervals in the circumferential direction corresponding to this. . In this case, the rigidity of the operating member 6 is increased, and the sliding movement of the operating member is more stable.

また、溝部１１において連結部１４側を向く内面１１ａが平面とされ、該内面１１ａに当接する連結部１４部分も平面になっていると説明したが、これに限定されるものではない。すなわち、溝部１１の内面１１ａと前記連結部１４部分とが当接した状態で、これらの間に隙間が形成されない構成であればよいことから、例えば、溝部１１の内面１１ａと前記連結部１４部分とが、凹曲面及び凸曲面により互いに隙間なく当接される構成であってもよい。 Moreover, although the inner surface 11a which faces the connection part 14 side in the groove part 11 was made into the plane, and it demonstrated that the connection part 14 part contact | abutted to this inner surface 11a was also made into the plane, it is not limited to this. That is, the inner surface 11a of the groove portion 11 and the connecting portion 14 portion may be in contact with each other as long as no gap is formed therebetween. May be configured such that the concave curved surface and the convex curved surface contact each other without a gap.

また、シール部５が、栓状体であるとしたが、これに限定されるものではない。すなわち、シール部５は、押し込み筒部１３に押し込まれて注出口３を開放可能な構成であればよいことから、例えば、押し込み筒部１３に押し込まれて破断可能とされた膜状体であってもよい。 Moreover, although the seal | sticker part 5 assumed that it was a plug-like body, it is not limited to this. That is, the seal portion 5 may be any film-like body that can be pushed into the push-in cylinder portion 13 and can open the spout 3 so that it can be broken by being pushed into the push-in tube portion 13. May be.

また、押し込み筒部１３の突起部１３ａが、下面視で円弧状をなしており、周方向に１つ形成されているとしたが、突起部１３ａの形状や数量は、前述の実施形態で説明したものに限定されない。 In addition, the protrusion 13a of the push-in cylinder 13 has an arc shape when viewed from below, and one protrusion 13a is formed in the circumferential direction. However, the shape and quantity of the protrusion 13a are described in the above embodiment. It is not limited to what you did.

また、装着筒４の注出筒１０、及び、操作部材６の当接筒部１２を開閉可能に覆うオーバーキャップが設けられていてもよい。
さらに、装着筒４の基筒８を容器本体２の口部２ａに螺合することに代え、アンダーカット嵌合（凹凸嵌合）など、その他の装着方法を採用してもよい。 Further, an overcap that covers the dispensing cylinder 10 of the mounting cylinder 4 and the abutting cylinder portion 12 of the operation member 6 so as to be openable and closable may be provided.
Furthermore, instead of screwing the base tube 8 of the mounting tube 4 into the mouth 2a of the container body 2, other mounting methods such as undercut fitting (concave / convex fitting) may be employed.

ここで、図５〜図８に示されるものは、前述の実施形態で説明した詰め替え容器１の変形例である。尚、前述の実施形態と同一部材には同一の符号を付し、その説明を省略する。 Here, what is shown in FIGS. 5 to 8 is a modification of the refill container 1 described in the above-described embodiment. In addition, the same code | symbol is attached | subjected to the same member as above-mentioned embodiment, and the description is abbreviate | omitted.

図５に示されるように、この変形例では、当接筒部１２のフランジ１２ａは、該当接筒部１２の外周面における容器軸Ｏ方向の上側部分から突設されている。また、連結部１４は、当接筒部１２の内周面における容器軸Ｏ方向の上側部分（容器軸Ｏ方向に沿うフランジ１２ａと略同一位置）から突設されている。また、連結部１４が離脱可能に係止される係止リブ１１ｃは、溝部１１における容器軸Ｏ方向の上端部付近に形成されている。 As shown in FIG. 5, in this modification, the flange 12 a of the abutting tube portion 12 is provided so as to protrude from the upper portion of the outer peripheral surface of the contact tube portion 12 in the container axis O direction. Further, the connecting portion 14 protrudes from an upper portion in the container axis O direction (substantially the same position as the flange 12 a along the container axis O direction) on the inner peripheral surface of the contact cylinder portion 12. In addition, a locking rib 11c to which the connecting portion 14 is detachably locked is formed in the vicinity of the upper end portion of the groove portion 11 in the container axis O direction.

この変形例では、連結部１４の下面と溝部１１の内面１１ａとの間の距離が、前述の実施形態で説明したものより大きくされているとともに、装着筒４に対する操作部材６のスライド移動量が大きくなっている。またこれに伴い、当接筒部１２の下端面と、基筒８の天壁８ａとの間の距離も、前述の実施形態で説明したものより大きくなっている。 In this modification, the distance between the lower surface of the connecting portion 14 and the inner surface 11a of the groove portion 11 is made larger than that described in the above embodiment, and the sliding movement amount of the operation member 6 with respect to the mounting cylinder 4 is increased. It is getting bigger. As a result, the distance between the lower end surface of the abutting tube portion 12 and the top wall 8a of the base tube 8 is also larger than that described in the above embodiment.

図６に示されるように、連結部１４は、軸状又は棒状をなしており、該連結部１４の下面は、矩形状の平面となっている。また、溝部１１は、幅狭のスリット状に形成されているとともに、その内面１１ｂが連結部１４において周方向を向く側面に摺接するようになっている。溝部１１の内面１１ａの形状は、連結部１４の下面の形状に対応して、矩形状の平面となっている。 As shown in FIG. 6, the connecting portion 14 has a shaft shape or a rod shape, and the lower surface of the connecting portion 14 is a rectangular plane. The groove portion 11 is formed in a narrow slit shape, and its inner surface 11b is in sliding contact with the side surface facing the circumferential direction in the connecting portion 14. The shape of the inner surface 11 a of the groove portion 11 is a rectangular plane corresponding to the shape of the lower surface of the connecting portion 14.

図５において、押し込み筒部１３は、注出筒１０内における容器軸Ｏ方向の上端部付近に配設されている。この変形例では、押し込み筒部１３の下端面のうち突起部１３ａ以外の部位と、シール部５の周壁５ｂの上端面との間の距離が、前述の実施形態で説明したものより大きくなっている一方、突起部１３ａの先端部（下端部）と周壁５ｂの上端面との間の距離は、前述の実施形態で説明したものと略同等である。つまり、この変形例では突起部１３ａの容器軸Ｏ方向に沿う長さ（突出量）が大きくなっており、図示の例では、突起部１３ａの突出量は、押し込み筒部１３の周壁のうち該突起部１３ａ以外の部位における容器軸Ｏ方向に沿う長さと、略同等となっている。 In FIG. 5, the push-in cylinder part 13 is disposed in the vicinity of the upper end part in the container axis O direction in the dispensing cylinder 10. In this modification, the distance between the portion of the lower end surface of the push-in cylinder portion 13 other than the protruding portion 13a and the upper end surface of the peripheral wall 5b of the seal portion 5 is larger than that described in the above embodiment. On the other hand, the distance between the tip (lower end) of the protrusion 13a and the upper end surface of the peripheral wall 5b is substantially the same as that described in the above-described embodiment. That is, in this modification, the length (projection amount) along the container axis O direction of the protrusion 13a is large. In the example shown in the drawing, the protrusion amount of the protrusion 13a is within the peripheral wall of the push-in cylinder portion 13. It is substantially the same as the length along the container axis O direction in the portion other than the protrusion 13a.

図６及び図７において、突起部１３ａの径方向内側を向く内面には、容器軸Ｏ方向に延びるリブ及び溝の少なくともいずれかが形成されている。
図示の例では、突起部１３ａの内面に、該内面から突出するとともに容器軸Ｏ方向に平行に延びるリブ１３ｂが、１つ形成されている。尚、リブ１３ｂは、容器軸Ｏ方向に延びていればよく、該容器軸Ｏ方向に平行でなくてもよい。具体的に、リブ１３ｂは、例えば、容器軸Ｏ方向に対して傾斜して延びていてもよく、容器軸Ｏ回りに螺旋状に延びていてもよい。また、リブ１３ｂが、複数形成されていてもよい。
また、リブ１３ｂの代わりに、突起部１３ａの内面から窪むとともに容器軸Ｏ方向に延びる溝を形成してもよい。また、これらリブ１３ｂ及び溝を両方形成してもよい。 6 and 7, at least one of a rib and a groove extending in the container axis O direction is formed on the inner surface of the protrusion 13a facing the radially inner side.
In the illustrated example, one rib 13b that protrudes from the inner surface and extends in parallel with the container axis O direction is formed on the inner surface of the protrusion 13a. The rib 13b only needs to extend in the container axis O direction, and may not be parallel to the container axis O direction. Specifically, for example, the rib 13b may extend while being inclined with respect to the container axis O direction, or may extend spirally around the container axis O. A plurality of ribs 13b may be formed.
Moreover, you may form the groove | channel extended in the container axis | shaft O direction while being depressed from the inner surface of the projection part 13a instead of the rib 13b. Moreover, you may form both these rib 13b and a groove | channel.

図５において、リブ１３ｂは、押し込み筒部１３の内周面における容器軸Ｏ方向の全長に亘り形成されている。また、リブ１３ｂの下端部は、下側に向かうに従い漸次その径方向の高さが低くなるように形成されている。具体的に、リブ１３ｂの径方向内側を向く面における下端部は、下側に向かうに従い漸次径方向外側に向かって傾斜している。また、突起部１３ａの外周面の下端部は、下側に向かうに従い漸次径方向内側に向かって傾斜している。
また、図７において、リブ１３ｂの下端部は、下側に向かうに従い漸次その周方向の幅が狭くなるように先鋭に形成されている。 In FIG. 5, the rib 13 b is formed over the entire length in the container axis O direction on the inner peripheral surface of the push-in cylinder portion 13. Moreover, the lower end part of the rib 13b is formed so that the height in the radial direction gradually decreases toward the lower side. Specifically, the lower end portion of the surface facing the radially inner side of the rib 13b is gradually inclined toward the radially outer side as it goes downward. Moreover, the lower end part of the outer peripheral surface of the protrusion 13a is gradually inclined inward in the radial direction as it goes downward.
In FIG. 7, the lower end portion of the rib 13b is formed to be sharp so that the width in the circumferential direction gradually becomes narrower toward the lower side.

図７に示されるように、突起部１３ａにおけるシール部５側の先端部（下端部）の容器軸Ｏ回り（周方向）に沿う長さは、該突起部１３ａにおけるシール部５とは反対側の基端部（上端部）の前記長さより小さくなっている。図示の例では、突起部１３ａの下端部における周方向の長さ（幅）は、突起部１３ａの上端部における幅の１／３程度とされている。 As shown in FIG. 7, the length along the container axis O (circumferential direction) of the tip portion (lower end portion) on the seal portion 5 side in the projection portion 13a is opposite to the seal portion 5 in the projection portion 13a. It is smaller than the length of the base end portion (upper end portion). In the illustrated example, the length (width) in the circumferential direction at the lower end of the protrusion 13a is about 程度 of the width at the upper end of the protrusion 13a.

突起部１３ａの上端部及び下端部は、それぞれ所定の幅で形成されている一方、該突起部１３ａにおいて上端部と下端部との間に位置する中間部は、下側に向かうに従い漸次その幅を狭めるように形成されている。図７に示される側面視で、突起部１３ａの中間部において周方向を向く両側面は、それぞれ凹円弧状をなしている。尚、前述の実施形態で説明した突起部１３ａの形状は、図７に２点鎖線で示されるような矩形状となっている。 The upper end and the lower end of the protrusion 13a are each formed with a predetermined width, while the intermediate portion located between the upper end and the lower end of the protrusion 13a gradually increases in width toward the lower side. It is formed to narrow. In the side view shown in FIG. 7, both side surfaces facing in the circumferential direction in the intermediate portion of the protruding portion 13 a each have a concave arc shape. In addition, the shape of the protrusion part 13a demonstrated by the above-mentioned embodiment is a rectangular shape as shown with a dashed-two dotted line in FIG.

図８は、この変形例の詰め替え容器１の容器本体２と本容器３０とを容器軸Ｏ方向に沿って相対的に接近移動させて、注出口３を開封した状態を示している。図８に示されるように、この変形例では、押し込み筒部１３の突起部１３ａが基筒８の天壁８ａから容器本体２内に向けて突出する量が、前述の実施形態より大きくなっているとともに、該突起部１３ａが、注出口３からシール部５を離間させやすい。 FIG. 8 shows a state where the spout 3 is opened by relatively moving the container body 2 and the main container 30 of the refill container 1 of this modification along the container axis O direction. As shown in FIG. 8, in this modification, the amount by which the protruding portion 13a of the push-in cylinder portion 13 protrudes from the top wall 8a of the base tube 8 into the container body 2 is larger than that in the above-described embodiment. In addition, the protrusion 13 a easily separates the seal portion 5 from the spout 3.

図５〜図８で説明した変形例によれば、突起部１３ａの内面に、リブ１３ｂ及び溝の少なくともいずれかが形成されているので、押し込み筒部１３がシール部５を押し込んで注出口３が開封（開放）された際に、内容物の液面に突起部１３ａのリブ１３ｂや溝を突き当て、該液面に作用する表面張力のバランスを崩して不均衡にすることによって、容器本体２内の内容物と、本容器３０内の空気との置換を開始させるきっかけとすることができる。従って、たとえ内容物の粘度が高いような場合であっても、容器本体２の内容物を注出口３に詰まらせることなく、確実に本容器３０に詰め替えることができる。 According to the modification described with reference to FIGS. 5 to 8, since at least one of the rib 13 b and the groove is formed on the inner surface of the protrusion 13 a, the push-in cylinder portion 13 pushes the seal portion 5 into the spout 3. When the container is opened (opened), the rib 13b or groove of the projection 13a is abutted against the liquid surface of the contents, and the balance of the surface tension acting on the liquid surface is broken to make the container body unbalanced. 2 can be used as a trigger for starting replacement of the contents in 2 and the air in the container 30. Accordingly, even if the viscosity of the contents is high, the contents of the container body 2 can be reliably refilled into the container 30 without clogging the spout 3.

また、突起部１３ａの先端部の幅が、基端部の幅より小さくなっており、突起部１３ａはシール部５側へ向けて先鋭（先細）形状とされているので、押し込み筒部１３がシール部５を押し込んで注出口３が開封された際に、内容物の液面に突起部１３ａの先端部を突き刺して、内容物を、周方向に沿って突起部１３ａの外側に拡げながら基端部側（本容器３０側）に向けて導入しやすくなる。 Further, the width of the distal end portion of the protruding portion 13a is smaller than the width of the proximal end portion, and the protruding portion 13a is sharpened (tapered) toward the seal portion 5 side. When the sealing part 5 is pushed in and the spout 3 is opened, the tip of the protruding part 13a is pierced into the liquid surface of the contents, and the contents are spread outside the protruding part 13a along the circumferential direction. It becomes easy to introduce toward the end side (the main container 30 side).

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.
