Description

本発明は、燃料電池、インクジェットプリンタ等における液体供給手段において、液体リザーバから液体を受容する液体アクセプタに液体を導く液体送受用ジョイント装置に関する。   The present invention relates to a liquid transmission / reception joint device for guiding a liquid from a liquid reservoir to a liquid acceptor that receives the liquid in a liquid supply unit in a fuel cell, an ink jet printer, or the like.

現在、インクジェットプリンタ、液体燃料を用いたライター、医療用薬液投与などにおいて、液体を収容しかつ流出する液体リザーバと、該液体リザーバから液体を受容する液体アクセプタとが着脱可能な液体供給手段を用いたものが広く普及されている。当該液体供給手段は、供給液体が不足したとき液体リザーバ自体を直接取り替えることができ、液体を本体内に搭載されているリザーブタンク等に直接供給することに比べ、液体によって手を汚すことがほとんどなく、安全性が高く、簡便に供給液体を補給できる。特に、供給液体が人体に影響のあるものや外気に触れると劣化が激しいものを用いる場合等には、大変有効な液体供給手段である。   Currently, in an ink jet printer, a lighter using liquid fuel, medical liquid medicine administration, etc., a liquid supply means in which a liquid reservoir for containing and flowing out a liquid and a liquid acceptor for receiving the liquid from the liquid reservoir are detachable are used. What has been widely spread. The liquid supply means can directly replace the liquid reservoir itself when there is a shortage of supply liquid, and in most cases, the hand is soiled by liquid compared to supplying the liquid directly to a reserve tank or the like mounted in the main body. The supply liquid can be easily replenished with high safety. In particular, this is a very effective liquid supply means when a supply liquid that affects the human body or a liquid that deteriorates drastically when exposed to outside air is used.

また、最近、液体を燃料として発電する燃料電池の開発が進められており、特にメタノールを燃料としたメタノール直接型燃料電池（DMFC）の開発が盛んに行われている。DMFCは、ノートパソコン、携帯可能な各種電子機器、携帯電話等に使用する次世代の新型電池として期待されている。メタノールは、人体に対する影響が大きく、吸入すると中枢神経を冒し、めまい、下痢を起こす。また、大量に吸入したり、眼に入ったりした場合は、視神経に障害を起こし失明する可能性が非常に高く、危険性が高く、有毒な液体である。そのためDMFCにおいても、一般需要者等にはメタノールを直接取り扱わせず、液体リザーバをカートリッジとしてメタノールを供給する手段の適用が考えられており、開発が行われている（特開２００３−３０８８７１、特開平８−１２３０１、特開２００３−３１７７５６など）。当該液体供給手段には、液体リザーバから液体アクセプタに液体を導く着脱可能な液体送受用ジョイントを有する必要がある。従来考えられているジョイントとして、特開平１０−７８９、特開平８−５００４２、特表２００３−５２８６９９、特開２００３−２６６７３９、特表２００１−５２４８９６、特開２０００−２８９２２５、特開平７−６８７８０、特開平５−２５４１３８、特開２００３−３３１８７９等が挙げられる。また、本発明者などが従来構想したジョイントの中で最も部品点数が少なく、単純な構造を有する液体送受用ジョイント装置を図１１、１２、１３に従来例として示す。   Recently, development of fuel cells that generate electricity using liquid as fuel has been promoted. In particular, methanol direct fuel cells (DMFC) using methanol as fuel have been actively developed. DMFC is expected as a next-generation new battery for use in notebook computers, various portable electronic devices, mobile phones and the like. Methanol has a great effect on the human body. When inhaled, it affects the central nervous system, causing dizziness and diarrhea. In addition, if inhaled in large quantities or enters the eye, it is very likely to cause optic nerve damage and blindness, and is a highly dangerous and toxic liquid. Therefore, in DMFC, it is considered to apply means for supplying methanol using a liquid reservoir as a cartridge instead of directly handling methanol for general consumers and the like (Japanese Patent Laid-Open No. 2003-308771). (Kaihei 8-12301, JP2003-317756, etc.). The liquid supply means needs to have a detachable liquid transmission / reception joint that guides the liquid from the liquid reservoir to the liquid acceptor. As joints conventionally considered, JP-A-10-789, JP-A-8-50042, JP2003-528699, JP2003-266739, JP2001-524896, JP2000-289225, JP7-68780, JP-A-5-254138, JP-A-2003-331879, and the like. Further, FIGS. 11, 12, and 13 show a liquid transmission / reception joint device having the simplest structure with the smallest number of parts among the joints conventionally conceived by the present inventors.

図１１は従来例の液体送受用ジョイント装置の、送液側ジョイント部６１と受液側ジョイント部６０を嵌着させていない状態の要部拡大断面図である。図１２は従来例の液体送受用ジョイント装置の送液側ジョイント部６１と受液側ジョイント部６０を嵌着させた状態を表す要部拡大断面図、図１３は図１２のＣ−Ｃ矢視断面図である。液体アクセプタ５０に形成された管状の受液側ジョイント部６０内には弁５３が配されており、付勢装置５１は受液側ジョイント部６０の内径が小さく形成されている部分と弁５３に係合して、常に弁５３を液体アクセプタ５０の外側（図１１で見た右側）方向へと付勢する。これにより、弁５３は弾性体パッキン５２に押し付けられている。   FIG. 11 is an enlarged cross-sectional view of a main part of the conventional liquid sending / receiving joint device in a state where the liquid feeding side joint portion 61 and the liquid receiving side joint portion 60 are not fitted. FIG. 12 is an enlarged cross-sectional view of a main part showing a state in which the liquid feeding side joint portion 61 and the liquid receiving side joint portion 60 of the conventional liquid feeding / receiving joint device are fitted, and FIG. 13 is a view taken along the line CC in FIG. It is sectional drawing. A valve 53 is arranged in a tubular liquid-receiving side joint portion 60 formed in the liquid acceptor 50, and the urging device 51 is connected to a portion where the inner diameter of the liquid-receiving side joint portion 60 is small and the valve 53. Engage and always urge the valve 53 toward the outside (right side as viewed in FIG. 11) of the liquid acceptor 50. Thereby, the valve 53 is pressed against the elastic packing 52.

同様に、液体リザーバ５７に形成された管状の送液側ジョイント部６１内には、弁５８が配されており、付勢装置５６は送液側ジョイント６１の内径が小さく形成されている部分と弁５８に係合して、常に弁５８を液体リザーバ５７の外側（図１１で見た左側）方向へと付勢する。これにより、弁５８は弾性体パッキン５５に押し付けられ、液体リザーバ５７内の液体は弁５８と弾性体パッキン５５によって密封され、液体リザーバ５７内に収容される。液体リザーバ５７の内圧と、付勢装置５６とによって弁５８が常に弾性体パッキンに押し付けられ液体リザーバ５７内の液体を密封しているので液漏れしない状態となっている。   Similarly, a valve 58 is disposed in a tubular liquid-feeding joint 61 formed in the liquid reservoir 57, and the urging device 56 includes a portion in which the inner diameter of the liquid-feeding joint 61 is formed small. Engaging with the valve 58, the valve 58 is always urged toward the outside of the liquid reservoir 57 (left side as viewed in FIG. 11). As a result, the valve 58 is pressed against the elastic packing 55, and the liquid in the liquid reservoir 57 is sealed by the valve 58 and the elastic packing 55 and accommodated in the liquid reservoir 57. The valve 58 is always pressed against the elastic packing by the internal pressure of the liquid reservoir 57 and the urging device 56 to seal the liquid in the liquid reservoir 57, so that no liquid leaks.

受液側ジョイント部６０の先端（Ｏリングを配設してある部分）を送液側ジョイント部６１内側に差し込み嵌着させると、向かい合った受液側ジョイント部６０の弁５３の端と、送液側ジョイント部６１の弁５８の端が係合し、互いに押し合うため、弁５３、５８の鍔状に形成されている（径の大きい）部分は弾性体パッキンから離れる。
図１３に示したとおり、弁５３、５８の鍔状に形成されている部分の外周には、１つまたは複数の溝６２がつけてある。液体リザーバ５７内の液体は、送液側ジョイント部６１の管内周と弁５８の溝６２との隙間を通り抜け、送液側ジョイント部６１管内を通り抜け受液側ジョイント部６０内に入りこみ、弾性体パッキン５２中央の孔を通り抜け、受液側ジョイント部６０の管内周と弁５３の溝６２との隙間を通り抜け、受液側ジョイント部６１を通過して、液体アクセプタ５０内に入り込む。
液体リザーバ５７の送液側ジョイント部６１と液体アクセプタ５０の受液側ジョイント部６０との嵌着を外すと、
受液側ジョイント部６０の弁５３は付勢装置５１に弾性体パッキン５２のある側へ付勢され、押し付けられているので、液体アクセプタ５０内の液体は外部へ液漏れしない状態になる。

As shown in FIG. 13, one or a plurality of grooves 62 are formed on the outer periphery of the portion of the valves 53, 58 formed in a bowl shape. The liquid in the liquid reservoir 57 passes through the gap between the pipe inner periphery of the liquid supply side joint part 61 and the groove 62 of the valve 58, passes through the liquid supply side joint part 61 pipe, enters the liquid reception side joint part 60, and is elastic. It passes through the hole in the center of the packing 52, passes through the gap between the pipe inner periphery of the liquid receiving side joint portion 60 and the groove 62 of the valve 53, passes through the liquid receiving side joint portion 61, and enters the liquid acceptor 50.
When the fitting between the liquid feeding side joint portion 61 of the liquid reservoir 57 and the liquid receiving side joint portion 60 of the liquid acceptor 50 is removed,
Since the valve 53 of the liquid receiving side joint portion 60 is urged and pressed by the urging device 51 toward the elastic packing 52, the liquid in the liquid acceptor 50 does not leak to the outside.

しかし、いずれのジョイント装置においても、部品点数が非常に多く複雑な構造となるため、小型化、コスト低減には限界がある。図１１、１２、１３に示す液体送受用ジョイント装置においても、少なくとも弁、付勢装置、Oリング、弾性体パッキンなどが必要であり、特許等で開示されているジョイントと同様に、小型化、コスト低減は非常に難しい。また、液体リザーバ、アクセプタ内の圧力が高くなると、弁等が開く構造を有するため、液漏れが生じやすい構造になっている。そのため、ジョイント構造の簡略化、高内圧下でも液漏れを起こさず、かつスムーズな着脱が可能なジョイント装置が強く求められている。その他、上記引用した例のうちの一例では、液体リザーバ、液体アクセプタ双方を嵌着させた際に液体の通過する流路内にバネ等が配設されており、ジョイントの使用中、液体にバネ等の成分が溶出してしまい、液体が汚染される問題点があった。   However, since any joint device has a complicated structure with a very large number of parts, there is a limit to downsizing and cost reduction. Also in the joint device for sending and receiving liquids shown in FIGS. 11, 12, and 13, at least a valve, a biasing device, an O-ring, an elastic packing, and the like are necessary. Like the joint disclosed in the patent, Cost reduction is very difficult. In addition, when the pressure in the liquid reservoir and the acceptor is increased, the valve or the like is opened, so that the liquid is likely to leak. Therefore, there is a strong demand for a joint device that can simplify the joint structure, prevent liquid leakage even under high internal pressure, and can be smoothly attached and detached. In addition, in one of the above-cited examples, a spring or the like is disposed in the flow path through which the liquid passes when both the liquid reservoir and the liquid acceptor are fitted. And the like components are eluted and the liquid is contaminated.

本発明の液体送受用ジョイントは、上記のかかる問題に鑑み、ジョイント構造を簡略化することにより、小型化、ローコスト化を図ると同時に、高い内圧下においても液漏れを起こさず、液体を汚染することのない、信頼性の高いジョイントを目指し鋭意検討した結果、上記の問題点を以下のようにして解決できることを見出した。   In view of the above-described problems, the liquid transmission / reception joint of the present invention simplifies the joint structure to reduce the size and cost, and at the same time, does not cause liquid leakage even under high internal pressure and contaminates the liquid. As a result of diligent investigation aiming for a reliable joint without any problems, it was found that the above problems can be solved as follows.

液体を収容する液体リザーバと前記液体リザーバから液体を受容する液体アクセプタを接続するジョイントにおいて、液体リザーバまたは液体アクセプタのいずれか一方もしくは両者のジョイントに、送液方向に対して予め貫通した切り込みを入れた弾性体を用い、前記弾性体を用いた液体リザーバまたは液体アクセプタの他方に、液体の流路を有するジョイントチューブを備える。   In the joint that connects the liquid reservoir that contains the liquid and the liquid acceptor that receives the liquid from the liquid reservoir, the liquid reservoir and / or the liquid acceptor has a notch penetrating in advance in the liquid feeding direction. A joint tube having a liquid flow path is provided on the other side of the liquid reservoir or the liquid acceptor using the elastic body.

本発明の液体送受用ジョイントは、上記のような構成を採用しているので以下に示す効果を奏する。
本発明では、従来品よりもジョイント構造を簡略化し、部品点数を少なくしてあるため、製品の小型化、ローコスト化を図ることが可能である。
同時に、液体リザーバまたは液体アクセプタ容器内が高い圧力下でも液漏れが生じ難い、信頼性の高いジョイントを実現できる。
また、当該ジョイントを、液体を燃料として発電する燃料電池の液体燃料カートリッジにも用いることができることがわかった。
本発明の液体送受用ジョイント装置は、ジョイントチューブ２の内径の大きさや弾性体パッキン１、１３の切り込みの大きさを変化させて、送受される液体の流量を加減することが可能である。加えて、送液側ジョイント部１８からの送液流量を１００ｍｌ／ｈｒ以下に押さえることが可能なため、適切な量の液体を少量ずつ供給することができ、特に燃料電池に本発明を使用した際はクロスオーバー現象（燃料の液体が燃料電池内の燃料極で反応を起こさないまま電解質に流入してしまう現象）を防止するという効果が得られる。
本発明に係る液体送受用ジョイント装置は、先に記した燃料電池や、インクカートリッジ、薬液投与用の容器に取り付けて使用するだけでなく、液体を容器から容器へと送受する目的のジョイント装置として様々な用途に使用できることはもちろんである。
本発明にかかる液体送受用ジョイント装置の弾性体パッキンは、ジョイントチューブの着脱の繰り返しに対して耐久性が良く、磨耗や変形等の劣化が無いため、弾性体パッキンへのジョイントチューブの着脱を繰り返した後も、元の切り込みが密着した形状に復元するので、液漏れの心配が無い。よって本発明の液体送受用ジョイント装置を取り付けた液体アクセプタや液体リザーバが使用済みになった後、液体を補充して再利用することが可能である。
また、本発明の液体送受用ジョイント装置は、内部の液体を付勢装置に接触させずに液体リザーバから液体アクセプタへ送受できるので、付勢装置の材料が溶け出して内部の液体に混じる事がないので、液体が汚染される心配がない。 Since the liquid transmission / reception joint of the present invention employs the above-described configuration, the following effects can be obtained.
In the present invention, since the joint structure is simplified and the number of parts is reduced as compared with the conventional product, it is possible to reduce the size and cost of the product.
At the same time, it is possible to realize a highly reliable joint in which liquid leakage hardly occurs even under high pressure in the liquid reservoir or the liquid acceptor container.
It was also found that the joint can be used for a liquid fuel cartridge of a fuel cell that generates power using liquid as fuel.
The joint device for sending and receiving liquid according to the present invention can change the flow rate of the liquid to be sent and received by changing the size of the inner diameter of the joint tube 2 and the size of the cuts of the elastic packings 1 and 13. In addition, since the liquid flow rate from the liquid supply side joint portion 18 can be suppressed to 100 ml / hr or less, an appropriate amount of liquid can be supplied little by little, and the present invention is used particularly for a fuel cell. In this case, an effect of preventing the crossover phenomenon (a phenomenon in which the liquid of the fuel flows into the electrolyte without causing a reaction at the fuel electrode in the fuel cell) can be obtained.
The joint device for liquid transmission / reception according to the present invention is not only used by being attached to the fuel cell, ink cartridge, chemical solution container described above, but also as a joint device for the purpose of transmitting / receiving liquid from container to container. Of course, it can be used for various purposes.
The elastic packing of the joint device for liquid transmission and reception according to the present invention has good durability against repeated mounting and dismounting of the joint tube, and there is no deterioration such as wear or deformation. After that, the original notch is restored to the close contact shape, so there is no risk of liquid leakage. Therefore, after the liquid acceptor and the liquid reservoir to which the liquid transmission / reception joint device of the present invention is attached are used, the liquid can be replenished and reused.
In addition, since the liquid transmission / reception joint device of the present invention can transmit and receive the liquid inside the liquid reservoir to the liquid acceptor without bringing the liquid into contact with the biasing device, the material of the biasing device may melt and mix with the liquid inside. Since there is no, there is no worry that the liquid will be contaminated.

以下に本発明の液体送受用ジョイント装置の実施例を示すが、本考案はこれらに限定されることはない。   Although the Example of the joint apparatus for liquid transmission / reception of this invention is shown below, this invention is not limited to these.

図１は本発明実施例の液体送受用ジョイントの一例を示す。液体送受用ジョイント装置の構造としては、液体アクセプタ（液体を受容する）側では、送液方向に対して予め貫通した切り込みを入れた弾性体、液体の流路を有するジョイントチューブ、付勢装置の三部品のみで、液体リザーバ側では送液方向に切り込みを入れた弾性体のみである。ジョイントチューブが各弾性体に挿入する際には、弾性体を通貫することなく、通貫する手前の適正な位置まで挿入する。ジョイントチューブの挿入位置は、送液流量や液体の性質によって異なり、具体的には弾性体の材質や切り込みの大きさ、ジョイントチューブの外径等によって異なる。ジョイントチューブ挿入の適正位置を「通貫する手前」としたのは、通貫させると、弾性体の歪が大きくなり、挿入前の形状に弾性復元し難くなり、液漏れを起こす心配があるためである。   FIG. 1 shows an example of a liquid transmission / reception joint according to an embodiment of the present invention. As a structure of the liquid sending / receiving joint device, on the liquid acceptor (receiving liquid) side, an elastic body with a notch penetrating in advance in the liquid feeding direction, a joint tube having a liquid flow path, and a biasing device There are only three parts, and on the liquid reservoir side, there is only an elastic body cut in the liquid feeding direction. When the joint tube is inserted into each elastic body, the joint tube is inserted to an appropriate position before passing through without passing through the elastic body. The insertion position of the joint tube varies depending on the liquid flow rate and the properties of the liquid, and specifically varies depending on the material of the elastic body, the size of the cut, the outer diameter of the joint tube, and the like. The appropriate position for inserting the joint tube is set to “before penetration”. If it is penetrated, the distortion of the elastic body will increase, making it difficult to elastically restore the shape before insertion, which may cause liquid leakage. It is.

弾性体としては、種々の形状のものが考えられるが、図2に示すように、ジョイントチューブが挿入する進行方向に対して切り込みを有しており、好ましくはジョイントチューブのガイド入り口を有している構造が望ましい。弾性体の材質としては、公知の弾性材料を用いることができ、各種ゴムやエラストマー等を用いることができる。具体的には、スチレン−ブタジエンゴム、ブタジエンゴム、シンジオタクチック1、２−ポリブタジエン、イソプレンゴム、アクリニトリル−ブタジエンゴム、クロロプレンゴム、エチレン−プロピレンゴム、エチレン−プロピレンターポリマー、ブチルゴム、アクリルゴム、クロルスルフォン化ポリエチレン、シリコーンゴム、フッ化ビニリデン系ゴム、テトラフロロエチレン・プロピレン系ゴム、テトラフロロエチレン・パーフロロメチルビニルエーテル系ゴム、フロロシリコーン系ゴム、エピクロルヒドリンゴム、多硫化ゴム、ウレタンゴム、天然ゴム等が挙げられ、これら１種または２種以上を混合して用いることができる。弾性体は、送液する液体の特性や、弾性体の摺動特性、永久圧縮ひずみ特性、反発弾性、耐溶性等の特性によって選択されることが望ましい。   As the elastic body, various shapes are conceivable. As shown in FIG. 2, the elastic body has a cut in the advancing direction in which the joint tube is inserted, and preferably has a guide inlet for the joint tube. The structure is desirable. As a material of the elastic body, a known elastic material can be used, and various rubbers, elastomers, and the like can be used. Specifically, styrene-butadiene rubber, butadiene rubber, syndiotactic 1,2-polybutadiene, isoprene rubber, acrylonitrile-butadiene rubber, chloroprene rubber, ethylene-propylene rubber, ethylene-propylene terpolymer, butyl rubber, acrylic rubber, Chlorsulfonated polyethylene, silicone rubber, vinylidene fluoride rubber, tetrafluoroethylene / propylene rubber, tetrafluoroethylene / perfluoromethyl vinyl ether rubber, fluorosilicone rubber, epichlorohydrin rubber, polysulfide rubber, urethane rubber, natural rubber These can be used, and one or more of these can be used in combination. The elastic body is desirably selected according to characteristics of the liquid to be fed, sliding characteristics of the elastic body, permanent compression strain characteristics, rebound resilience, resistance to dissolution, and the like.

ジョイントチューブは、弾性体に挿入し、弾性体内の液体を送り込む機能と耐溶性を有していれば良く、使用する材質は問わない。チューブの内径は送液流量、送液する液体の特性、外径は弾性体の出口の大きさを考慮して決定する。材質は、金属、プラスチック、木材、セラミック等を用いることができ、好ましくは金属、プラスチックが望ましい。具体的には、金属は、ステンレス、アルミ、鉄、銅、銀、白金、金等が挙げられる。プラスチックでは、ポリエチレン、ポリプロピレン、塩化ビニル樹脂、ポリスチレン、ABS樹脂、メタクリル樹脂、ポリエチレンテレフタレート、ポリアミド、ポリカーボネート、ポリアセタール、ポリブチレンテレフタレート、変性ポリフェニレンエーテル、ポリフェニレンサルファイド、液晶ポリマー、ポリサルホン、ポリエーテルサルホン、ポリアリレート、ポリエーテルエーテルケトン、ポリフタルアミド、ポリイミド、ポリエーテルイミド、ポリアミドイミド、ポリメチルペンテン、フッ素樹脂、ポリフッ化ビニリデン、ＴＥＦＥ、ＰＦＡ、フェノール樹脂、ユリア樹脂、メラミン樹脂、不飽和ポリエステル、ジアリルフタレート樹脂、エポキシ樹脂、ポリウレタン樹脂、シリコーン樹脂等が挙げられる。   The joint tube may be inserted into the elastic body and has a function of feeding the liquid in the elastic body and resistance to melting, and any material may be used. The inner diameter of the tube is determined in consideration of the liquid flow rate, the characteristics of the liquid to be fed, and the outer diameter in consideration of the size of the outlet of the elastic body.

また、液体リザーバと液体アクセプタの着脱の際、ジョイントチューブが弾性体からスムーズに抜けるようにするため、付勢装置等を利用してもよい。該付勢装置はコイルバネや板バネ等でも良いが、目的の効果が得られるのであれば、どのような物を使用しても良い。   Further, an urging device or the like may be used so that the joint tube can be smoothly removed from the elastic body when the liquid reservoir and the liquid acceptor are attached and detached. The biasing device may be a coil spring, a leaf spring, or the like, but any device may be used as long as the desired effect can be obtained.

図１、図２、図３に示す液体リザーバ８は液体を入れる容器であり、内部の液体を注出するために送液側ジョイント部１８が取り付けられている。該送液側ジョイント部１８は、該液体リザーバ８に予め孔２０が貫通開口してあり、該孔２０の縁端部２２はリザーバ８外側方向へ僅かに肉厚に形成され、縁端部２２の縁の（孔２０内周方向への）端は他の部分より肉薄な形状に形成されている。   The liquid reservoir 8 shown in FIGS. 1, 2, and 3 is a container for storing a liquid, and a liquid supply side joint portion 18 is attached to pour out the liquid inside. The liquid supply side joint portion 18 has a hole 20 penetratingly opened in the liquid reservoir 8 in advance, and an edge end portion 22 of the hole 20 is formed to be slightly thicker toward the outer side of the reservoir 8. The edge (in the inner peripheral direction of the hole 20) of the edge is formed thinner than the other parts.

上記の孔２０に、弾性体パッキン１３の一方の端（外径の小さい方）をリザーバ８内側に向けて、つまり液体リザーバ８外側から、図３に示す矢印Ａ方向へ向けて挿着する。弾性体パッキン１３のもう一方の端（外径の大きい方）にはフランジ２３が設けてあり、該フランジ２３は孔２０縁端部２２の肉薄部分の縁と嵌合する形状に形成されており、接着材等で外れないように装着されている。リザーバ８内部の液体が漏れない方法であれば接着手段は問わない。そして、液体リザーバ８の外側から、孔２０と弾性体パッキン１３内側の空間１５を覆うようにして保護フィルム６を配置してある。該保護フィルム６により、液体リザーバ８を使用する以前に弾性体パッキン１３の内側の空間１５内にゴミ等の異物が入って、ジョイントチューブ２が弾性体パッキン１３に入りづらくなったり、液体リザーバ８内部液体の流路を塞いだりしてしまうことを防いでいる。
また、弾性体パッキン１３の外径の小さい方の端から空間１５までは切り込み１４が入っていて、切り込み１４は通常、上下の弾性体同士が密着して開口していない状態となっているが、弾性体パッキン１３の材料特性により弾性変形するので開閉自在になっている。弾性体パッキン１３内側は途中から切り込み１４に向けて、切り込み１４の部分の手前まで傾斜部分２５が施されている。 One end (the smaller outer diameter) of the elastic packing 13 is inserted into the hole 20 toward the inside of the reservoir 8, that is, from the outside of the liquid reservoir 8 toward the arrow A direction shown in FIG. A flange 23 is provided at the other end (the larger outer diameter) of the elastic packing 13, and the flange 23 is formed in a shape that fits the edge of the thin portion of the edge 20 of the hole 20. It is mounted so that it does not come off with an adhesive or the like. Any bonding means may be used as long as the liquid inside the reservoir 8 does not leak. The protective film 6 is disposed from the outside of the liquid reservoir 8 so as to cover the hole 20 and the space 15 inside the elastic packing 13. Due to the protective film 6, foreign matter such as dust enters the space 15 inside the elastic packing 13 before the liquid reservoir 8 is used, and the joint tube 2 does not easily enter the elastic packing 13. This prevents the flow path of the internal liquid from being blocked.
In addition, a cut 14 is provided from the end of the elastic packing 13 having a smaller outer diameter to the space 15, and the cut 14 is normally in a state where the upper and lower elastic bodies are not in close contact with each other and are not opened. Since it is elastically deformed by the material characteristics of the elastic packing 13, it can be freely opened and closed. The inside of the elastic packing 13 is provided with an inclined portion 25 from the middle toward the notch 14 up to the front of the notch 14 portion.

図１、図２に示す液体アクセプタ７は、前記液体リザーバ８から供給される液体を注入するための容器である。
液体を注入するための受液側ジョイント部１９は、該液体アクセプタ７に予め孔２１が貫通開口してあり、該孔２１の縁端部１２は、液体アクセプタ７外側方向へ肉厚に突出して形成され、縁端部１２の縁の（孔２１内周方向への）端は他の部分より肉薄な形状に形成されている。 The liquid acceptor 7 shown in FIGS. 1 and 2 is a container for injecting the liquid supplied from the liquid reservoir 8.
The liquid receiving side joint part 19 for injecting the liquid has a hole 21 penetratingly opened in the liquid acceptor 7 in advance, and the edge part 12 of the hole 21 protrudes to the outside of the liquid acceptor 7 with a thickness. The edge of the edge portion 12 (in the inner circumferential direction of the hole 21) is formed in a thinner shape than the other portions.

上記の孔２１に、弾性体パッキン１の径の小さい方の端を、液体アクセプタ７内側に向けて、つまり液体アクセプタ７外側から図２に示す矢印Ｂ方向へ向けて挿着する。弾性体パッキン１のもう一方の端（径の大きい方）にはフランジ２４が設けてあり、該フランジ２４は孔２１縁端部１２の肉薄部分の縁と嵌合する形状に形成されている。   The end with the smaller diameter of the elastic packing 1 is inserted into the hole 21 toward the inside of the liquid acceptor 7, that is, from the outside of the liquid acceptor 7 toward the arrow B direction shown in FIG. A flange 24 is provided at the other end (the larger diameter) of the elastic packing 1, and the flange 24 is formed in a shape that fits the edge of the thin portion of the edge 21 of the hole 21.

前記弾性体パッキン１の後方、つまり液体アクセプタ７外側方向から、予め付勢装置３を片方の端に装着してあるジョイントチューブ２を、図２に示す矢印B方向へ向けて、弾性体パッキン１内の空間１６の途中まで差し込み、このジョイントチューブ２外周に鍔状に形成されたフランジ４とストッパー９との間にケース５の頂面が配置されるように、ケース５を装着する。該ケース５は分割された円筒状に形成されており、分割されているパーツを嵌合させ組み合わせると円筒を形成する構造になっていて、円筒は底面側が開放面に、頂面は閉塞状になっていて、開放面（底面）側の縁は、孔２１縁端部１２の、液体アクセプタ７外側方向に突出している部分に溶着等の手段により固定されていて、閉塞面（頂面）側の中央にはジョイントチューブ２の細い部分を摺動自在に通すサイズの孔が開口貫通されている。ケース５と縁端部１２との固定方法は溶着でなくても、内部の液体が漏れない方法であれば固定手段は限定しない。   From the back of the elastic packing 1, that is, from the outside of the liquid acceptor 7, the joint tube 2 having the urging device 3 mounted in advance on one end is directed in the direction of arrow B shown in FIG. The case 5 is mounted so that the top surface of the case 5 is arranged between the flange 4 formed on the outer periphery of the joint tube 2 and the stopper 9. The case 5 is formed in a divided cylindrical shape. When the divided parts are fitted and combined, a cylinder is formed. The cylinder has an open surface on the bottom side and a closed surface on the top surface. The edge on the open surface (bottom surface) side is fixed to the portion of the edge portion 12 of the hole 21 that protrudes toward the outside of the liquid acceptor 7 by means such as welding, and is on the closed surface (top surface) side. A hole of a size through which a thin portion of the joint tube 2 is slidably passed is opened at the center of the tube. Even if the fixing method between the case 5 and the edge portion 12 is not welding, the fixing means is not limited as long as the liquid inside does not leak.

ケース５は無くとも本発明は成り立つが、付勢装置３やジョイントチューブ２等に不用意に外力がかかった時に、これら部品を外力から保護し、ゴミ等の異物がジョイントチューブ２や付勢装置３等に入り込みこれら部品の動作を妨げてしまう事を防ぐ目的と、送液側・受液側の各ジョイント部を連結する際に、ジョイントチューブ２が斜めになったり弾性体パッキン１から外れたりすることを防ぐため、ケース５を装着した方がより本発明の液体送受用ジョイント装置に対しての信頼性が増すので好ましい。   The present invention can be realized without the case 5, but when an external force is applied to the biasing device 3 or the joint tube 2 or the like inadvertently, these parts are protected from the external force, and foreign matters such as dust are protected from the joint tube 2 or the biasing device. The joint tube 2 is slanted or disengaged from the elastic packing 1 when connecting the joint parts on the liquid feeding side and the liquid receiving side, for the purpose of preventing them from entering the 3rd etc. In order to prevent this, it is preferable to attach the case 5 because the reliability of the joint device for liquid transmission and reception according to the present invention is increased.

ジョイントチューブ２に装着されている付勢装置３は、付勢装置本体のバネ等の性質である弾性復元力により片方の端を弾性体パッキン１のフランジ２４に、もう一方の端はジョイントチューブ２のフランジ４に接し、それぞれを押圧している。これにより、送液側ジョイント１８が受液側ジョイントに嵌合していない時、ジョイントチューブ２のフランジ４は常にケース５の頂面（閉塞面）側へと付勢されて、ジョイントチューブ２が弾性体パッキン１の切れ込み１１内に入り込まないようになっている。   The biasing device 3 attached to the joint tube 2 has one end to the flange 24 of the elastic packing 1 and the other end to the joint tube 2 by an elastic restoring force which is a property of a spring or the like of the biasing device body. Are in contact with the flanges 4 and pressed. Thereby, when the liquid feeding side joint 18 is not fitted to the liquid receiving side joint, the flange 4 of the joint tube 2 is always urged toward the top surface (blocking surface) side of the case 5 so that the joint tube 2 is The elastic packing 1 does not enter into the cut 11.

なお、孔２０、孔２１、ケース５やジョイントチューブ２は、製作が簡単であるため外周が円形状になっている例をここでは説明しているが、外周を円形に限定しなくとも同様の効果は得られる。   In addition, although the hole 20, the hole 21, the case 5, and the joint tube 2 have been described here as an example in which the outer periphery is circular because it is easy to manufacture, the same is true even if the outer periphery is not limited to a circle. The effect is obtained.

前記弾性体パッキン１の外径の小さい方の端には切り込み１１が入っていて、切り込み１１は通常は上下の弾性体同士が密着して開口していない状態となっているが、弾性体パッキン１の材料特性により弾性変形するので開閉自在になっている。図４は弾性体パッキン１のみを径の小さい方の側から見た図であり、図３の右側面図になる。弾性体パッキン１の内側の途中から切り込みの１１の部分に向けて、切り込み１１手前の部分までは傾斜部分２６が施されている。   The elastic packing 1 has a notch 11 at the end of the smaller outer diameter, and the notch 11 is usually in a state where the upper and lower elastic bodies are not in close contact with each other, but the elastic packing. Since it is elastically deformed by the material characteristics of 1, it can be opened and closed freely. FIG. 4 is a view of only the elastic packing 1 as seen from the smaller diameter side, which is a right side view of FIG. An inclined portion 26 is provided from the middle of the elastic packing 1 toward the notch 11 portion up to the notch 11 portion.

本発明実施例にかかる液体送受用ジョイントを使用する際は、液体アクセプタ７に液体リザーバ８を嵌着させる。この時に送液側、受液側のジョイントも互いに嵌合する。詳しく説明すると、受液側ジョイント部１９のジョイントチューブ２の（弾性体パッキンにはまっていない側の）先端が、送液側ジョイント部１８の保護フィルム６に刺さり保護フィルム６は破れ、さらにジョイントチューブ２先端は図３に示す矢印Ａ方向へと移動し弾性体パッキン１３内側の空間１５内を通り、切り込み１４に入り、ジョイントチューブ２に押されて弾性体パッキン１３の切り込み１４は弾性変形し開口する。弾性体パッキン１３が変形した状態を図８にて表す。   When the liquid transmission / reception joint according to the embodiment of the present invention is used, the liquid reservoir 8 is fitted to the liquid acceptor 7. At this time, the joint on the liquid feeding side and the liquid receiving side are also fitted to each other. More specifically, the tip of the joint tube 2 of the liquid-receiving side joint portion 19 (on the side not attached to the elastic packing) is pierced by the protective film 6 of the liquid-feeding side joint portion 18 and the protective film 6 is torn. 2 is moved in the direction of arrow A shown in FIG. 3 and passes through the space 15 inside the elastic packing 13 and enters the notch 14, and is pushed by the joint tube 2 so that the notch 14 of the elastic packing 13 is elastically deformed and opened. To do. A state where the elastic packing 13 is deformed is shown in FIG.

同時に、ジョイントチューブ２のストッパー９は、前記送液側ジョイント部１８の縁端部２２に接し、押されて図２に示す矢印Ｂ方向へと移動する。ケース５内にあるジョイントチューブ２のフランジ４も同様に移動するので付勢装置３がフランジ４に押されて収縮し、ジョイントチューブ２のもう一方の先端は弾性体パッキン１内部へ入り、切り込み１１の間に入り込み、ジョイントチューブ２に押されて切り込み１１は弾性変形し開口する。この状態を図５の要部断面図に表す。図６は図５の左側面図であり、要部（弾性体パッキン１）を拡大した図である。   At the same time, the stopper 9 of the joint tube 2 comes into contact with the edge portion 22 of the liquid feeding side joint portion 18 and is pushed to move in the direction of arrow B shown in FIG. Since the flange 4 of the joint tube 2 in the case 5 moves in the same manner, the urging device 3 is pushed by the flange 4 and contracts, and the other end of the joint tube 2 enters the elastic packing 1 and is cut 11. The notch 11 is elastically deformed and opened by being pushed by the joint tube 2. This state is shown in the main part sectional view of FIG. FIG. 6 is a left side view of FIG. 5 and is an enlarged view of a main part (elastic packing 1).

弾性体パッキン１３内側には、切り込み１４方向（図９に示す矢印Ａ方向）に向けて、内径の中央方向へ徐々に先端がすぼまるよう傾斜部分２５が形成されている。同様に、弾性体パッキン１内側には、切り込み１１方向（図１０に示す矢印Ｂ方向）に向けて、内径の中央方向へ徐々に先端がすぼまるよう傾斜部分２６が形成されている。送液側と受液側の両ジョイント部を嵌着させる際、ジョイントチューブ２の両端が各弾性体パッキン１、１３内に挿入されるが、弾性体パッキン１、１３内には前記傾斜部分２５、２６が形成されているので、ジョイントチューブ２の両端は傾斜部分２５、２６をガイドに各切り込み１１、１４内にスムーズに挿入でき、弾性体１、１３の切り込み１１、１４は弾性変形・開口しやすくなっている。   An inclined portion 25 is formed inside the elastic packing 13 so that the tip gradually narrows toward the center of the inner diameter in the direction of the cut 14 (the direction of arrow A shown in FIG. 9). Similarly, an inclined portion 26 is formed inside the elastic packing 1 so that the tip gradually narrows toward the center of the inner diameter in the direction of the cut 11 (the direction of arrow B shown in FIG. 10). When fitting both the liquid-feeding side and liquid-receiving side joints, both ends of the joint tube 2 are inserted into the elastic packings 1 and 13, but the inclined portions 25 are inserted into the elastic packings 1 and 13. , 26 are formed so that both ends of the joint tube 2 can be smoothly inserted into the notches 11, 14 with the inclined portions 25, 26 as guides, and the notches 11, 14 of the elastic bodies 1, 13 are elastically deformed and open. It is easy to do.

ジョイントチューブ２が弾性体パッキン１、１３の切り込み１１、１４をそれぞれ開口させたことにより、液体リザーバ８内部の液体が切り込み１４の開口した部分から空間１５内に流入し、ジョイントチューブ２内の流路１７を通過して、受液側ジョイント部１９の弾性体パッキン１内の空間１６を通過し、切り込み１１の開口した部分から流出して液体アクセプタ７へと流入する。以上により液体リザーバ８内の液体は液体アクセプタ７に少しずつ移動し、送液側・受液側双方のジョイントは目的を果たす。この時、液体は弾性体パッキン１３とジョイントチューブ２と弾性体パッキン１にのみ接触し、ケース５や付勢装置３には接触しない。   Since the joint tube 2 has opened the cuts 11 and 14 of the elastic packings 1 and 13, the liquid inside the liquid reservoir 8 flows into the space 15 from the opened part of the cut 14, and the flow in the joint tube 2. It passes through the path 17, passes through the space 16 in the elastic packing 1 of the liquid receiving side joint portion 19, flows out from the opened portion of the cut 11, and flows into the liquid acceptor 7. Thus, the liquid in the liquid reservoir 8 moves little by little to the liquid acceptor 7, and the joints on both the liquid feeding side and the liquid receiving side serve the purpose. At this time, the liquid contacts only the elastic packing 13, the joint tube 2, and the elastic packing 1, and does not contact the case 5 or the urging device 3.

ジョイントチューブ２の内径の大きさや弾性体パッキン１、１３の切り込みの大きさを変化させると、送受される液体の流量を加減することが可能である。加えて、送液側ジョイント部１８からの送液流量を１００ｍｌ／ｈｒ以下に押さえることが可能なため、液体を少量ずつ、かつ適切な量で供給することができる。   If the size of the inner diameter of the joint tube 2 and the size of the cuts of the elastic packings 1 and 13 are changed, the flow rate of the liquid to be sent and received can be adjusted. In addition, since the liquid supply flow rate from the liquid supply side joint portion 18 can be suppressed to 100 ml / hr or less, the liquid can be supplied in small amounts and in an appropriate amount.

なお、液体アクセプタ７と液体リザーバ８が互いに接する面は、双方が嵌合する形状で、嵌合後、液体を補充している間に不意に強い外力がかかった場合等には容易には外れにくく、かつ液体リザーバ８を新しいものと交換する際には液体アクセプタ７からの取り外しが簡単に行える形状に形成されるのが望ましい。また、液体リザーバと液体アクセプタの形は、各図に示すような略直方体に限定せず、使用する機器等の形状や取り付け部位によって形状を変えて形成することはもちろんである。   Note that the surfaces where the liquid acceptor 7 and the liquid reservoir 8 are in contact with each other are shaped so that they can be easily fitted together, and can be easily detached when a strong external force is applied while refilling the liquid after fitting. It is difficult to form a shape that can be easily removed from the liquid acceptor 7 when the liquid reservoir 8 is replaced with a new one. Further, the shape of the liquid reservoir and the liquid acceptor is not limited to a substantially rectangular parallelepiped as shown in each drawing, and it is needless to say that the shape is changed depending on the shape of the device or the like to be used and the attachment site.

なお、幾度も液体リザーバ８と液体アクセプタ７を着脱、つまり送液側・受液側のジョイントを着脱させても、弾性体の材料の選択が適切であれば、弾性体パッキン１、１３の切り込み１１、１４の弾性復元力に変化は無く、磨耗や変形等の劣化に対する耐久性は高いことがわかった。このため、弾性体パッキン１、１３にジョイントチューブ２の着脱を繰り返し行い、ジョイントチューブを外した後も、弾性体パッキン１、１３の切り込み１１、１４は密着して閉じた形状に復元する。よって、液体アクセプタ７や液体リザーバ８は互いの嵌合を外しても、どちらからも液漏れをおこす心配がない上、これら液体アクセプタ７や液体リザーバ８が使用済みになった後、液体リザーバ８には液体を補充して、双方を再利用することが可能である。   In addition, even if the liquid reservoir 8 and the liquid acceptor 7 are attached and detached several times, that is, the joints on the liquid feeding side and the liquid receiving side are attached and detached, the elastic packings 1 and 13 can be cut if the selection of the elastic material is appropriate. It was found that there was no change in the elastic restoring force of 11 and 14 and the durability against deterioration such as wear and deformation was high. Therefore, after the joint tube 2 is repeatedly attached to and detached from the elastic packings 1 and 13 and the joint tube is removed, the cuts 11 and 14 of the elastic packings 1 and 13 are restored to a closed shape. Therefore, even if the liquid acceptor 7 and the liquid reservoir 8 are disengaged from each other, there is no risk of liquid leakage from either of them, and after the liquid acceptor 7 and the liquid reservoir 8 are used, the liquid reservoir 8 It is possible to refill the liquid and reuse both.

なお、上記実施例では、液体リザーバ８側に備えられた送液側ジョイント部１８が、弾性体パッキン１３と保護フィルム６にて構成され、液体アクセプタ７側に備えられた受液側ジョイント部１９は、弾性体パッキン１と、ジョイントチューブ２と、付勢装置３とそれらを収納、保護するためのケース５で構成されているが、液体リザーバ８と液体アクセプタ７の各ジョイント部同士の部品を交換しても、目的の効果を得る事が可能である。
つまり、液体リザーバ８側の送液側ジョイント部１８の部品を弾性体パッキン１と、ジョイントチューブ２と、付勢装置３とそれらを収納、保護するためのケース５にて構成し、液体アクセプタ７の受液側ジョイント部１９の部品を弾性体パッキン１３と保護フィルム６にて構成しても液体の送受用ジョイント装置としての役割を果たすことが出来る。 In the above embodiment, the liquid supply side joint portion 18 provided on the liquid reservoir 8 side is constituted by the elastic packing 13 and the protective film 6, and the liquid reception side joint portion 19 provided on the liquid acceptor 7 side. Consists of an elastic packing 1, a joint tube 2, an urging device 3 and a case 5 for storing and protecting them. The components of the joint portions of the liquid reservoir 8 and the liquid acceptor 7 Even if it is exchanged, the desired effect can be obtained.
That is, the components of the liquid supply side joint portion 18 on the liquid reservoir 8 side are constituted by the elastic packing 1, the joint tube 2, the biasing device 3, and the case 5 for storing and protecting them, and the liquid acceptor 7 Even if the components of the liquid receiving side joint portion 19 are constituted by the elastic packing 13 and the protective film 6, it can serve as a joint device for liquid transmission and reception.

受液側ジョイント部１９を使用する以前にゴミ等の異物が付着して、いざ使用する際に液体の流れを妨げることの無いよう、ジョイントチューブ２のケース５外側に出ている先端には、保護用のキャップ等を予め付けておくと、なお好ましい。   In order to prevent foreign matter such as dust from adhering before using the liquid-receiving side joint portion 19 and preventing the flow of liquid during use, the tip of the joint tube 2 that protrudes outside the case 5 is It is more preferable to attach a protective cap or the like in advance.
