Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は熱溶着により成形されるナイロン(商品名・以下同じ)製密閉容器 の溶着部保護構造に関する。 The present invention relates to a welded portion protection structure for a sealed container made of nylon (trade name, the same applies hereinafter) formed by heat welding.

【0002】[0002]

【従来の技術】[Prior art]

従来ナイロン製の密閉容器例えば内燃機関の冷却水用リザーブタンクには、開 放端を有する箱状のボディと板状のカバーとを、両者の周縁部同士を熱溶着した ものが用いられている。その熱溶着の方法としては摩擦により発熱させる振動溶 着等の方法が用いられ、溶着部分には周知のように溶融代としてのリブを設け、 また溶けバリのはみ出し防止用の溝や立上り縁等を設けている。 Conventionally, a closed container made of nylon, for example, a reserve tank for cooling water of an internal combustion engine, has a box-shaped body having an open end and a plate-shaped cover, and their peripheral portions are thermally welded to each other. . As a method of heat welding, there is used a method such as vibration welding in which heat is generated by friction, a rib as a melting margin is provided in the welded portion as is well known, and a groove or a rising edge for preventing protrusion of melted burr is used. Is provided.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来の上記のようなナイロン製密閉容器に例えば冷却水(LLC)を満たすと 、溶着部分が容器内側に露出しており、水に直接触れるので、ナイロンの場合加 水分解によって溶着部の材質が劣化し、強度が低下する。劣化が進行すると熱や 圧力によって溶着部が破損するに至り、液洩れ等の事故となる。ナイロンの加水 分解は一般の容器壁面においては実用上問題にならないが溶着部分は材質の劣化 の進行が特に早くなるものである。 When the conventional nylon sealed container as described above is filled with cooling water (LLC), for example, the welded portion is exposed inside the container and directly comes into contact with water. It deteriorates and its strength decreases. If the deterioration progresses, the welded part will be damaged by heat and pressure, resulting in an accident such as liquid leakage. Hydrolysis of nylon does not pose a practical problem on the wall surface of general containers, but the deterioration of the material at the welded part is particularly rapid.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

ナイロン製密着容器を形成するボディとカバ−の熱溶着部分の内側に耐水性の 弾性パッキンを配置し、ボディとカバーとの間で液密に挟持させることによって 密閉容器の内部と溶着部との水の流通を遮断したものである。 A water-resistant elastic packing is placed inside the heat-sealed portion of the body and the cover that form a nylon tight-fitting container, and it is liquid-tightly sandwiched between the body and the cover. It cuts off the flow of water.

【0005】[0005]

【作用】[Action]

この密閉容器は内部に水を満たした場合、溶着部はパッキンに保護されて水に 触れることがないので、加水分解等による材質の劣化を招くことがなく、水に起 因する溶着部の強度低下が生じない。 When the inside of this sealed container is filled with water, the welded part is protected by the packing and does not come into contact with water, so the deterioration of the material due to hydrolysis does not occur, and the strength of the welded part caused by water No decrease occurs.

【0006】[0006]

【実施例】【Example】

図1に実施例を示す。ナイロン製のボディ2とカバ−3とはそれぞれの周縁部 4、5が振動溶着により溶着されて密閉容器1を形成する。密閉容器1はこの例 では自動車エンジンの冷却水(ロングライフクーラント,LLC)用リザーブタ ンクである。周縁部4、5の接合部分に溶着部6が形成されており、その内側に パッキン7が配置されている。パッキンは合成ゴム製のOリング7であり周縁部 4、5においてボディ2とカバー3との間に弾力的に挟持される。 An example is shown in FIG. Nylon body 2 and cover 3 have their peripheral portions 4, 5 welded by vibration welding to form closed container 1. In this example, the closed container 1 is a reserve tank for cooling water (long life coolant, LLC) of an automobile engine. A welded portion 6 is formed at the joining portion of the peripheral edge portions 4 and 5, and a packing 7 is arranged inside thereof. The packing is an O-ring 7 made of synthetic rubber, and is elastically sandwiched between the body 2 and the cover 3 at the peripheral edges 4, 5.

【0007】 図2に示すようにOリング7は矢印8の方向に圧縮されて、ボディ2、カバー 3に液密に密着している。振動溶着される前のボディ2、カバー3、Oリング7 の形状を図3に示す。ボディ2の周縁部4には、頂部が溶融して溶着部6となる リブ9と、その内側にOリング7を保持するガイドとなる内周リブ10が設けら れ、Oリング7が装着される。カバー3の周縁部5の外周にバリ受け用の外周リ ブ11が設けられる。カバー3は図1のように板状でなく、ボデー2に対向する 開口端縁を有する箱状のものであってもよい。ボディ2、カバー3の周縁部4、 5を突き合わせ矢印12方向に押圧して振動溶着すれば、リブ9の頂部が図2の ように溶けバリ13、14となって流出し、溶着部6が形成されるとともに、溶 けバリ13は外周リブ11によって、また溶けバリ14はOリング7によっては み出しが阻止される。さらにOリング7はボディ2とカバー3との間で矢印8の 圧縮を受けて挟持される。As shown in FIG. 2, the O-ring 7 is compressed in the direction of the arrow 8 and is in liquid-tight contact with the body 2 and the cover 3. The shapes of the body 2, cover 3 and O-ring 7 before vibration welding are shown in FIG. The peripheral portion 4 of the body 2 is provided with a rib 9 that melts at the top to form a welded portion 6 and an inner peripheral rib 10 that serves as a guide for holding the O-ring 7 inside the O-ring 7. It An outer peripheral rib 11 for receiving a burr is provided on the outer periphery of the peripheral portion 5 of the cover 3. The cover 3 may not have a plate shape as shown in FIG. 1, but may have a box shape having an opening edge facing the body 2. When the body 2 and the peripheral portions 4 and 5 of the cover 3 are butted against each other and pressed in the direction of the arrow 12 for vibration welding, the tops of the ribs 9 are melted as burrs 13 and 14 and flow out as shown in FIG. While being formed, the melted burr 13 is prevented from protruding by the outer peripheral rib 11, and the melted burr 14 is prevented from protruding by the O-ring 7. Further, the O-ring 7 is sandwiched between the body 2 and the cover 3 by being compressed by the arrow 8.

【0008】 このようにして密閉容器1の器壁を形成する溶着部6の内側を液密に遮断する 手段を講じたので、密閉容器1の注入口15から水を注入して満たしたとき、溶 着部6はOリング7に保護されて水に触れないから、加水分解による劣化現象は 生じない。In this way, since the means for liquid-tightly blocking the inside of the welded portion 6 forming the container wall of the closed container 1 is taken, when water is injected from the injection port 15 of the closed container 1 to fill it, Since the welded portion 6 is protected by the O-ring 7 and does not come into contact with water, the deterioration phenomenon due to hydrolysis does not occur.

【0009】[0009]

【考案の効果】 この考案は上記のように密閉容器を形成するための溶着部を内側において液密 にパッキンで保護したので、密閉容器内の水に触れて溶着部が劣化することがな く、そのための強度低下による破損や液洩れが生じない。As described above, according to the present invention, the welded portion for forming the closed container is liquid-tightly protected by the packing inside so that the welded portion is not deteriorated by contact with water in the closed container. Therefore, damage or liquid leakage due to the decrease in strength does not occur.
