栓体の製造方法に関するものである。
従来の技術 従来この種の栓体は、ゴム栓を内包するに際して、上側
栓と下側栓を嵌合するもの（実開昭５９−１６９８３５
号）、射出成形にて周囲を密封するもの（実公昭５８−
３７３９６号）がある。
発明が解決しようとする問題点 前者の技術によれば、上側栓と下側栓とが単に嵌合して
いるだけなので、栓体を組んでプラスチック容器の口部
に溶着する際の栓体の移送時に雑菌が入る危険性が高く
、したがって使用時プルトップ切除後ゴム栓の表面をア
ルコールで清浄にしなければならなかった。また後者の
技術によれば、ゴム栓のまわりを射出成形により密封す

射出成形したプラスチックとの接合が難しく部分的に未
溶着部分が発生し内部の輸液がこの未溶着部分を通じて
ゴム栓内に侵入することとなり衛生上問題があった。
そこで、本発明は以上の点に鑑み以下の目的を達成しよ
うとするものである。
（１）密封性の高い栓体を得ること ゴム栓を完全に密封して外気の雑菌から完全に隔離して
衛生性を高めること。
（２）下側枠と下側枠の溶着が完全であること超音波溶
着であるので、溶着する部材を選ばす溶着でき、しかも
溶着が完全である。
（３）栓体の衛生性が高いこと 問題点を解決するための手段 そこで、本発明は、 「天板部上側にプルリングを有し下側にスコアを有する
下側枠を該天板部に対応する位置に薄肉板部を有する下
側枠とによりゴム栓を内包する栓体の製造方法において
、ゴム栓の側面にて下側枠と下側枠を当接し、次いで超
音波振動を印加して下側枠と下側枠を溶着する」 ものである。
作用 本発明は以上のように構成したので、溶着面が荒れてい
たりあるいは不純物（例えば水や油など）が介在したと
しても溶着を完全にすることができ、したがってゴム栓
を完全に密封することができ滅菌時に水分が入ることの
ないきわめて衛生的な栓体を製造することができるので
ある。
実施例 本発明の一実施例を図面に基づき説明する。
１は下側枠、２は下側枠、３はゴム栓である。
下側枠１は、天板部１１を有しその上側に一体にプルリ
ング１２を有し、その下側にスコア１３を有する。さら
に下側枠ｌは、スコアの外側に周状突状１４を一体に有
し、さらに周状突条１４の外側には接合突状１５を有す
る。下側枠２は下側枠ｌの天板部に対向する位置に金属
針にて容易に刺し入れることのできる薄肉板２１を有し
、その外側には下方へ延びる先端にフランジ２３を備え
る筒状部２２を有し、筒状部２２の上方には接合突条２
４を有する。ゴム栓３は全体に平板状であり、中央に平
板部３１を有し下側枠１の周状突条１４に対応する位置
には、周状突条１４の突出する長さと同等の深さの溝で
ある周状溝、３２を有しこの周状溝３２の外側に上方へ
突出する周状突条３３を有する。なおこのゴム栓の周状
突条３３は、平板３１の高さよりも若干小さいものであ
る。これらの部材は、下側枠ｌの天板部１．１と接合突
状１５及び下側枠２の薄肉板２１と接合突状２４で形成
される凹部にゴム栓３は収納される。
これらの部材を第１図に示すように、先ず下側枠２を、
治具５の上に載置し、下側枠２を固定する。下側枠２の
上部にはゴム栓３をセットしておく。
次に工具ホーン４を垂下して下側枠１をゴム栓３及び下
側枠２の上に被せ、それぞれ下側枠ｌの接合突状１５と
下側枠２の接合突状２４とを接触させる。このとき第２
図に示すように下側枠１の接合突状１５は、内側さらに
突出する側突状１５ａを有し、下側枠２の接合突状２４
には外側に側突状２４ａを有する。なお下側枠の側突状
１５ａは下側枠の側突状２４ａより長く形成されている
。
このために両者を当接させると外側に空隙部６が生じる
。
次いで、工具ホーン４に２０ＫＩＩｚ程度の超音波を印
加して、工具ホーン４にて振幅を増幅して下側枠ｌに超
音波振幅を伝える。この超音波振幅により下側枠の接合
突条１５と下側枠の接合突条２４との互いの接触面にて
発熱する。工具ホーン４の押圧により溶けたプチスラッ
クは、ゴム栓側へ溶出し、第３図に示すようにゴム栓３
を圧迫して突起７を形成する。空隙部６が、消滅し互い
の接触面が溶着するまで超音波を工具ホーン１４に印加
する。
冷却して溶着が完了した後、工具ホーン４を除去し、治
具から取り去って本製造方法を終了する。
上記実施例により製造された栓体を第４図に示す。第４
図は、この栓体をプラスチック製容器の口部８に溶着し
た状態を示すものである。
上記実施例によれば、超音波により溶着するものである
ので、下側枠ｌと下側枠２との接触面に水分や油などの
異物が介在したとしても溶着することができ、この部分
に未溶着部分が発生することがないのである。したがっ
てゴム栓を完全に密封することができゴム栓内に水分、
雑菌の侵入を完全に防止できるのである。また上記実施
例では突起７が形成されているのでこの栓体は、ゴム栓
３が外側の上側枠１及び上側枠２にて密に連結されてい
るので、ゴム栓３に注射針を刺し入れて使用してもゴム
栓３がはずれることがないのである。
第５図に他の実施例を示した。これは、ゴム栓の同条突
起３３′の外側面に同条の凹条３４′を有する。この凹
条３４′の位置は、上側枠１と上側枠２との接触面に対
応する部分に形成するものである。この凹条３４′を形
成することにより超音波振幅により加熱し溶出したプラ
スチックを流し込むことを容易にすることができる。第
５図に示す凹条３４′の断面形状は半月状であるが、第
６図に示すようにアンダーカット形状に形成した凹条３
４＃にするとゴム栓３＃に埋め込まれるのでアンカー効
果が大きい。
また、第６図に示すようにゴム栓３＃の厚みを上側枠、
１″と上側枠２＃とで囲まれた四部と同等にすることに
より溶着時にゴム栓３＃を圧縮しながら溶着することが
できるので、さらにゴム栓の抜は防止を完全にできるの
である。
上記実施例では、印加する超音波の振動数は２ＯＫＨｚ
としたが特にこの数値に限定されるものではないが、プ
ラスチックの溶着時間、溶着強度等を考慮すると超音波
の振動数は１０〜３０　Ｋ　Ｈ２が好しくこれらの超音
波を工具ホーンで増幅することにより１０〜１００μｍ
