Description

本発明は、容器口部に螺子締結され、容器内容物の取り出しに使用されるコネクタに関するものである。   The present invention relates to a connector that is screwed to a container mouth and is used to take out the contents of a container.

従来、各種医薬が充填されたバッグなどの容器は、その口部に螺子締結されたキャップを取り外し、該口部に中空筒状形状のコネクタを接続し、このコネクタに点滴用のチューブを接続し、容器内の医薬を投与するという手段が採用されている。   Conventionally, a container such as a bag filled with various medicines has a cap that is screwed to the mouth, a hollow cylindrical connector connected to the mouth, and a drip tube connected to the connector. The means of administering the medicine in the container is employed.

このようなコネクタは、一般に、容器口部に巻き締めて螺子締結されるものであり、例えば特許文献１には、内壁面に容器口部の外面に形成されている螺条と係合するネジ山を備えたコネクタが開示されている。
特開２００６−４２８５６号 Such a connector is generally screwed around a container mouth and screwed. For example, Patent Document 1 discloses a screw that engages with a thread formed on an outer surface of a container mouth on an inner wall surface. A connector with a mountain is disclosed.
JP 2006-42856

ところで、上記のような公知のコネクタは、これを容器口部に３６０度以上回転させて巻き締めて固定している。１回の回転で巻き締め固定することができず、途中でコネクタを持ち変えてコネクタを回転させなければならないという煩わしさがあった。   By the way, the known connector as described above is fixed by rotating and rotating it around the container mouth by 360 degrees or more. There was a problem that it was not possible to fasten and fix by one rotation, and it was necessary to change the connector on the way and rotate the connector.

従って、本発明の目的は、持ち変えることなく、誰でも１周未満の回転で容易に容器口部に巻き締め固定することが可能なコネクタを提供することにある。   Therefore, an object of the present invention is to provide a connector that can be easily wound and fixed to a container mouth by any rotation less than one turn without changing.

本発明によれば、外面に切欠き部を有する螺条が形成された容器口部に螺子締結され且つ該容器口部に螺子締結された状態で容器口部内空間と連通する貫通口を供えたコネクタにおいて、
該コネクタの内面壁には、螺条が３６０度以上にわたって形成されており、該コネクタの螺条よりも上側部分には、該コネクタが容器口部に巻き締められたときに容器口部の上端に当接する当接部が形成されており、
該コネクタを容器口部に巻き締めたとき、容器口部の上端が前記当接部に当接することによって画定される巻き締め終了時において、該コネクタの螺条と容器口部の螺条とは、１８０度乃至２７０度にわたって互いに係合しているとともに、
該コネクタの螺条には、前記巻き締め終了時において、前記容器口部の螺条に形成された切欠き部に係合する上方に突出した突起部が形成されていることを特徴とするコネクタが提供される。 According to the present invention, there is provided a through-hole that is screw-fastened to a container mouth portion in which a thread having a notch portion is formed on the outer surface and communicates with the inner space of the container mouth portion while being screw-fastened to the container mouth portion. In the connector,
On the inner wall of the connector, a thread is formed over 360 degrees, and the upper part of the connector is threaded on the upper end of the container mouth when the connector is wound around the container mouth. A contact portion is formed to contact the
When the connector is wound around the container mouth portion, at the end of winding tightening defined by the upper end of the container mouth portion coming into contact with the contact portion, the screw thread of the connector and the screw thread of the container mouth portion are , Engaged with each other over 180 to 270 degrees,
The connector is characterized in that the screw thread of the connector is formed with a projecting portion protruding upward to engage with a notch formed in the thread of the container mouth at the end of the tightening. Is provided.

本発明のコネクタは、医薬等の内容物が充填された容器の口部に被せて、これを巻き締めて容器口部の外面に螺子係合させることにより固定されるが、このような巻き締めは、１周（３６０度）以上にわたって回転させる必要はなく、半周（１８０度）乃至３／４周（２７０度）の回転でよい。従って、容器口部にコネクタを巻き締めて固定する際に、誰でもコネクタを持ち変えることなく、容易に容器口部に固定することができる。   The connector of the present invention is fixed by covering the mouth portion of a container filled with contents such as pharmaceuticals and winding it and screwing it to the outer surface of the container mouth portion. , It is not necessary to rotate over one turn (360 degrees) or more, and it may be a half turn (180 degrees) to a 3/4 turn (270 degrees). Therefore, when the connector is wound and fixed on the container mouth portion, anyone can easily fix the connector to the container mouth portion without changing the connector.

また、本発明においては、コネクタの螺条に上方に突出した突起が形成されており、巻き締め終了時において、この突起が容器の螺条に形成された切欠き部に係合するような位置に設定されている。即ち、本発明のコネクタでは、螺子係合幅が短く設定されており、半周乃至３／４周の回転で巻き締めが終了する。このため、一般の使用者が巻き締め終了を認識することができず、さらにコネクタを回転させようとするおそれがあるが、本発明では、巻き締め終了時に上記突起が容器口部の螺条の切欠き部に係合するため、巻き締め終了の閉塞感を使用者に与え、これにより、必要以上にコネクタを回転させようとするなどの不都合を有効に防止することができる。   Further, in the present invention, a protrusion protruding upward is formed on the screw thread of the connector, and the position where the protrusion engages with the notch formed on the screw thread of the container at the end of winding tightening. Is set to That is, in the connector of the present invention, the screw engagement width is set to be short, and the tightening is completed by the rotation of a half turn to a 3/4 turn. For this reason, a general user cannot recognize the end of tightening and may further attempt to rotate the connector. However, in the present invention, when the tightening is finished, the protrusion is formed on the thread of the container mouth. Since it engages with the notch, it gives the user a feeling of closure at the end of the tightening operation, thereby effectively preventing inconveniences such as trying to rotate the connector more than necessary.

また、上記の突起と切欠き部との係合により、コネクタが安定に容器口部に保持され、螺子係合幅が短く設定されたことによるコネクタのガタツキなども有効に防止することができる。   In addition, due to the engagement between the protrusion and the notch, the connector can be stably held at the container opening, and rattling of the connector due to the short screw engagement width can be effectively prevented.

図１を参照して、全体として１で示す本発明のコネクタは、全体的に中空筒状の形態を有しているものであり、その下方部分に形成されている基筒３と基筒３の上端に一体に連なっている連結筒５とからなっており、基筒３から連結筒５にわたって貫通口６が形成されている。   Referring to FIG. 1, the connector of the present invention generally indicated by 1 has a hollow cylindrical shape as a whole, and a base cylinder 3 and a base cylinder 3 formed in the lower part thereof. And a through-hole 6 is formed from the base tube 3 to the connecting tube 5.

基筒３は、その内部に後述する容器口部３０が挿入されて巻き締め固定される部分であり、その内壁面には、螺条７が形成され、その外面には、巻き締めに際しての滑り止め防止用のローレット９が形成されている。   The base tube 3 is a portion in which a container mouth portion 30 to be described later is inserted and fixed by tightening, and a screw thread 7 is formed on the inner wall surface, and the outer surface is slipped at the time of tightening. A knurling 9 for preventing the stop is formed.

連結筒５は、ホース乃至チューブ等の部材が接続される部分であり、上部にいくにしたがって小径となっているテーパー形状を有しており、その外面には、ホース乃至チューブを接続したときの抜けを防止するための周方向に延びる突起１１が軸方向に複数個設けられている。   The connecting cylinder 5 is a portion to which a member such as a hose or a tube is connected, and has a tapered shape having a smaller diameter toward the top, and the outer surface of the connecting tube 5 when the hose or tube is connected. A plurality of protrusions 11 extending in the circumferential direction for preventing disconnection are provided in the axial direction.

上記のコネクタ１の内壁には、基筒３と連結筒５との境界部分に段差部１３が形成されている。この段差部１３は、コネクタ１を容器口部に巻き締めたときに容器口部３０の上端との当接部となる部分であり、連結筒５の内面から段差部１３よりも下方に延びたリング１５が設けられており、コネクタ１を巻き締めたときに、このリング１５の外周面が容器口部３０内周面に当接し、段差部１３は容器口部３０の上端に当接することとなり、これにより、コネクタ１の巻き締め状態が安定に保持され容器口部３０とコネクタ１とのシール性が確保されることとなる。   On the inner wall of the connector 1, a step portion 13 is formed at the boundary portion between the base tube 3 and the connecting tube 5. The step portion 13 is a portion that becomes a contact portion with the upper end of the container mouth portion 30 when the connector 1 is wound around the container mouth portion, and extends below the step portion 13 from the inner surface of the connecting cylinder 5. A ring 15 is provided, and when the connector 1 is tightened, the outer peripheral surface of the ring 15 comes into contact with the inner peripheral surface of the container mouth portion 30, and the step portion 13 comes into contact with the upper end of the container mouth portion 30. As a result, the tightened state of the connector 1 is stably maintained, and the sealing performance between the container mouth portion 30 and the connector 1 is ensured.

また、図２を参照して、容器口部３０は、ボトルのように容器と一体に形成されるものであったり、或いは袋状容器の開口部にヒートシールなどにより接着固定されるスパウトと呼ばれるものであり、その外面には、少なくとも１８０度以上にわたって延びている螺条３１が形成されており、螺条３１の下方には、この容器口部３０に装着されるキャップに設けられたタンパーエビデントバンドを切り離すためのラチェット３３や容器の搬送等に用いられるサポートリング３５などが設けられている。   In addition, referring to FIG. 2, the container opening 30 is formed integrally with the container like a bottle, or is called a spout that is bonded and fixed to the opening of the bag-like container by heat sealing or the like. A thread 31 extending at least 180 degrees or more is formed on the outer surface of the thread 31. Below the thread 31, a tamper shrimp provided on a cap attached to the container mouth 30 is formed. A ratchet 33 for separating the dent band, a support ring 35 used for transporting the container, and the like are provided.

また、上記螺条３１には、切欠き部５０が形成されている。この切欠き部５０は、図２から理解されるように、例えば９０度間隔で形成されており、各切欠き部５０が直線状に位置するように配置されている。かかる容器口部３０には、図示されていないが、螺条３１との螺子係合によりキャップが巻き締め固定され、これにより、容器内が密封されるようになっているが、切欠き部５０の形成により、例えば容器内に内容物を充填し、容器口部３０にキャップを締結した後、シャワー等により洗浄を行なったとき、キャップの内面と容器口部３０の外面との間に侵入した洗浄液が速やかに外部に排出されるようになっている。   The thread 31 has a notch 50 formed therein. As can be understood from FIG. 2, the notches 50 are formed at intervals of 90 degrees, for example, and are arranged so that the notches 50 are linearly located. Although not shown in the figure, the cap is wound and fixed by screw engagement with the screw 31 so that the inside of the container is hermetically sealed. For example, when the container is filled with the contents and the cap is fastened to the container mouth 30 and then washed by a shower or the like, it enters between the inner surface of the cap and the outer surface of the container mouth 30. The cleaning liquid is quickly discharged to the outside.

本発明において、図１に示すコネクタ１は、図２の容器口部３０からキャップを取り外した後に、その基筒１に容器口部３０に被せ、閉栓方向に回転させて螺条３１にコネクタ１の螺条７を螺子係合せしめることにより、容器口部１に巻き締められることとなる。この巻き締め状態は、図３に示したようなものとなる。即ち、巻き締め状態では、前述したように、リング１５の外周面が容器口部３０内周面に当接し、容器口部３０の上端が段差部１３に当接することとなる。   In the present invention, the connector 1 shown in FIG. 1 has the cap 1 removed from the container mouth portion 30 in FIG. 2, and then the base tube 1 is put on the container mouth portion 30 and rotated in the closing direction to connect the connector 1 to the screw 31. When the thread 7 is screwed, the container mouth 1 is wound. This tightened state is as shown in FIG. That is, in the tightened state, as described above, the outer peripheral surface of the ring 15 comes into contact with the inner peripheral surface of the container mouth portion 30, and the upper end of the container mouth portion 30 comes into contact with the step portion 13.

一般に、図３に示すような巻き締め状態で、コネクタ１の連結筒５にホースやチューブ等の部材を接続し、容器口部３０の開口からコネクタ１の貫通口６を介して医薬等の容器内容物が排出され、接続されたホースやチューブから例えば患者に医薬等の内容物が投与されるわけである。   In general, a member such as a hose or a tube is connected to the connecting tube 5 of the connector 1 in a tightened state as shown in FIG. 3, and a container such as a medicine is passed from the opening of the container port 30 through the through-hole 6 of the connector 1. The contents are discharged, and the contents such as medicine are administered to the patient from the connected hose or tube, for example.

本発明においては、コネクタ１の螺条７が３６０度以上にわたって形成されているが、図３の巻き締め状態において、コネクタ１の螺条７と容器口部３０の螺条３１とが１８０度乃至２７０度にわたって互いに係合していることが重要であり、このような角度幅で螺条７と螺条３１とが係合するように、螺条７の下端位置が設定されている。   In the present invention, the screw 7 of the connector 1 is formed over 360 degrees or more. However, in the winding state of FIG. 3, the screw 7 of the connector 1 and the screw 31 of the container mouth 30 are 180 degrees or more. It is important to engage with each other over 270 degrees, and the lower end position of the screw 7 is set so that the screw 7 and the screw 31 are engaged with such an angular width.

図４は、従来公知のコネクタを容器口部３０に巻き締めた状態での螺子係合状態を示す展開図であるが、図４から理解されるように、容器口部３０の上端が段差部１３に当接している巻き締め状態では、コネクタ１の螺条７は、３６０度以上にわたって容器口部３０の螺条３１と係合しており、螺条７の全体が螺条３１の下側に入り込んだ状態となっている。このような螺子係合状態は、キャップと容器口部３０との螺子係合状態と全く同様であり、これにより、十分な螺子係合幅を確保し、良好なシール性を確保しているわけである。   FIG. 4 is a developed view showing a screw engagement state in a state in which a conventionally known connector is wound around the container mouth portion 30. As can be understood from FIG. 4, the upper end of the container mouth portion 30 is a stepped portion. 13, the thread 7 of the connector 1 is engaged with the thread 31 of the container opening 30 over 360 degrees, and the entire thread 7 is below the thread 31. It is in a state of getting in. Such a screw engagement state is exactly the same as the screw engagement state between the cap and the container mouth portion 30, thereby ensuring a sufficient screw engagement width and ensuring a good sealing property. It is.

しかしながら、上記のような螺子係合状態とするためには、少なくとも１周にわたってコネクタ１を回転させなければならず、従って、人によっては、コネクタ１を巻き締める際に、コネクタ１を持ち変えなければならないという煩わしさがある。   However, in order to achieve the above-described screw engagement state, the connector 1 must be rotated over at least one round. Therefore, some people must change the connector 1 when tightening the connector 1. There is annoyance that must be.

これに対して、本発明では、巻き締め状態において、コネクタ１の螺条７と容器口部３０の螺条３１との係合幅が１８０度乃至２７０度の範囲に設定されているため、上記のような煩わしさはない。例えば図５には、係合幅を１８０度に設定した場合について、螺条７の１８０度分が螺条３１の下側に位置し、残りの部分が螺条３１の上側に位置した状態に保持されている。即ち、このような巻き締め状態とするためには、コネクタ１を半回転すればよく（係合幅を２７０度に設定した場合には、３／４回転させればよい）、従って、巻き締めの途中でコネクタ１を持ち変える必要はなく、誰でも容易に、巻き締めを行なうことが可能となるものである。   On the other hand, in the present invention, in the tightened state, the engagement width between the screw 7 of the connector 1 and the screw 31 of the container mouth 30 is set in a range of 180 degrees to 270 degrees. There is no such annoyance. For example, in FIG. 5, when the engagement width is set to 180 degrees, 180 degrees of the thread 7 are positioned below the thread 31 and the remaining part is positioned above the thread 31. Is retained. That is, in order to achieve such a tightening state, the connector 1 may be rotated half a half (if the engagement width is set to 270 degrees, it may be rotated by 3/4). There is no need to change the connector 1 in the middle of this, and anyone can easily perform the tightening.

尚、本発明においては、螺子係合幅が３６０度未満（１８０度乃至２７０度）に設定されているため、螺子係合の観点からは、螺条７の長さを３６０度未満に設定することは可能である。しかしながら、この場合には、コネクタ１を成形する際、成形後の型抜き時において、コネクタ１の内面に螺条７が形成されていない部分が存在するため、型抜きによって発生する応力が不均等になり、この結果、コネクタ１自体が変形してしまうという不都合を生じることがある。このような成形時の不都合を防止するため、螺条７は、３６０度以上の長さとすべきである。   In the present invention, since the screw engagement width is set to less than 360 degrees (180 degrees to 270 degrees), the length of the thread 7 is set to less than 360 degrees from the viewpoint of screw engagement. It is possible. However, in this case, when the connector 1 is molded, there is a portion where the thread 7 is not formed on the inner surface of the connector 1 at the time of mold release after molding, so that the stress generated by the mold release is uneven. As a result, the connector 1 itself may be deformed. In order to prevent such inconvenience at the time of molding, the thread 7 should have a length of 360 degrees or more.

また、本発明においては、従来公知のコネクタと比較すると螺子係合幅が短くなっているが、コネクタ１は、容器内容物を密封保存するために使用されるものではないため、螺子係合幅が短いことによるシール性低下に関する問題は全くない。   In the present invention, the screw engagement width is shorter than that of a conventionally known connector. However, since the connector 1 is not used for hermetically storing the container contents, the screw engagement width. There is no problem regarding the deterioration of the sealing performance due to the short length.

さらに本発明においては、図１に示されているように、コネクタ１の螺条７には、上方に突出した突起部７ａが形成されている。この突起部７ａは、図５の巻き締め終了時の螺子締結状態の展開図から理解されるように、巻き締め終了時において、容器口部３０の螺条３１に形成された切欠き部５０に係合するような位置に設けられているものである。   Furthermore, in the present invention, as shown in FIG. 1, the screw 7 of the connector 1 is formed with a protruding portion 7 a protruding upward. As can be understood from the developed view of the screw fastening state at the end of winding tightening in FIG. 5, the protrusion 7 a is formed on the notch 50 formed in the thread 31 of the container mouth portion 30 at the end of winding fastening. It is provided in the position which engages.

即ち、前述した構造を有する本発明のコネクタでは、先にも述べたように、螺子係合幅が短く設定されており、１周未満（半周乃至３／４周）の回転で巻き締めが終了するため、一般の使用者が巻き締め終了を認識することができず、さらにコネクタを回転させようとするおそれがある。しかるに、上記のような突起７ａを螺条７に設けておくと、巻き締め終了時に突起７ａが容器口部３０の螺条３１の切欠き部に係合することとなり、この結果、巻き締め終了時にカチッという音や抵抗感などの閉塞感を使用者に与え、これにより、必要以上にコネクタを回転させようとするなどの不都合を有効に防止することができることとなる。   That is, in the connector of the present invention having the above-described structure, as described above, the screw engagement width is set short, and the tightening is completed by rotation of less than one turn (half to 3/4 turn). Therefore, a general user cannot recognize the end of the tightening and may further attempt to rotate the connector. However, if the protrusion 7a as described above is provided on the thread 7, the protrusion 7a engages with the notch of the thread 31 of the container mouth portion 30 when the winding is finished, and as a result, the winding is finished. Sometimes, the user is given a sense of blockage, such as a clicking sound or resistance, thereby effectively preventing inconveniences such as trying to rotate the connector more than necessary.

さらには、上記のような突起７ａを形成しておくことにより、巻き締め終了時に該突起７ａが切欠き部５０に係合するため、コネクタ１が安定に容器口部３０に保持され、螺子係合幅が短く設定されたことによるコネクタ１のガタツキなども有効に防止することができる。   Furthermore, by forming the projection 7a as described above, the projection 7a engages with the notch 50 at the end of winding, so that the connector 1 is stably held at the container mouth 30 and the screw engagement is achieved. It is possible to effectively prevent rattling of the connector 1 due to the fact that the combined width is set short.

さらに、本発明のコネクタ１において、図６の好適例に示すように、コネクタ１の基筒３の内面壁にリブ２０を設けることもできる。このリブ２０は、容器口部３０との当接部となる段差部１３と螺条７の上端との間の位置に設けられ、且つ高さ方向に延びているものであり、リブ２０の高さは螺条７の突出長さよりも低く、巻き締めたときに、容器口部３０の内面に接触しないように設けられている。このようなリブ２０を基筒３の内面壁の全周にわたって均等に配置しておくことにより、巻き締められたコネクタ１の傾倒がリブ２０によって矯正され、コネクタ１は常に正常な状態に維持され、コネクタ１のガタツキ等を確実に防止することができ、容器口部３０に安定に保持することが可能となる。   Furthermore, in the connector 1 of the present invention, as shown in the preferred example of FIG. 6, ribs 20 can be provided on the inner wall of the base tube 3 of the connector 1. The rib 20 is provided at a position between the step portion 13 serving as a contact portion with the container mouth portion 30 and the upper end of the thread 7 and extends in the height direction. The height is lower than the projecting length of the thread 7 and is provided so as not to contact the inner surface of the container mouth portion 30 when the thread 7 is tightened. By arranging such ribs 20 evenly over the entire inner wall of the base tube 3, the tilt of the wound connector 1 is corrected by the ribs 20, and the connector 1 is always maintained in a normal state. The rattling of the connector 1 can be reliably prevented and can be stably held in the container opening 30.

上述した本発明のコネクタ１は、ポリエチレン、ポリプロピレンに代表される各種熱可塑性プラスチックを用いての射出成形等の公知の手段によって容易に成形され、例えば各種医薬が充填された医療用包装バッグなどの容器の口部に巻き締められ、このコネクタ１にホースやチューブ等の管を接続して患者等への医薬の投入に利用される。勿論、ボトルなどの飲料容器などの口部に接続し、コネクタ１から直接容器内容物を喫飲するなどの用途に適用することも可能である。   The connector 1 of the present invention described above is easily molded by known means such as injection molding using various thermoplastics represented by polyethylene and polypropylene, such as a medical packaging bag filled with various medicines. It is wound around the mouth of the container and connected to the connector 1 with a tube such as a hose or a tube, which is used for injecting medicine to a patient or the like. Of course, it is also possible to connect to a mouth part of a beverage container such as a bottle and to apply the contents of the container directly from the connector 1.
