〔問題点を解決するための手段〕
本発明は上記の問題点を全て解消しようとする

体成形した合成樹脂製蓋枠の前記受縁上に、天板
部を構成する表示紙葉を載置し、次いで加熱装置
を外側斜め上方から前記突出周条に押し当て、そ
の上部及び内側を軟化溶融させつつ蓋枠を回転さ
せ、前記突出周条を全周にわたり表示紙葉の周端
部上面に被覆溶着させることを要旨とするもので
ある。
〔作用及び実施例〕
第１図、第２図は本発明に係る製造法を具体化
して示した一実施例であり、以下、これについて
本製造法の作用と併せて説明する。
蓋枠１はスチロールその他の樹脂で形成され、
嵌着周縁不と適宜な幅で内周に突出している受縁
３、及び前記嵌着周縁の延長方向で受縁外周から
上方に突出している突出周条４とからなり、この
蓋枠１は公知の成形手段によつて一体に成形され
る。
本製造法では、まず、このように構成された蓋
枠１の受縁３上に、所要の印刷表示を表面に施し
た表示紙葉６を載置する。この表示紙葉６は通常
用いられる紙材のほか、紙材の下面にポリエチレ
ン、ポリプロピレン等の樹脂フイルムをラミネー
トしたものも含まれる。前記表示紙葉６を載置す
るにあたつては、表示紙葉６の直径ｂをあらかじ
め突出周条４の内径b′に相当させておけば、表示
紙葉６を供給する際に軽く押圧するのみで確実に
受縁３上に載置されるから、載置する位置の位置
決めは不必要である（第１図）。
次いで、加熱装置７を外側斜め上方から突出周
条４に押し当てて加熱する。この加熱装置として
は適宜な装置が用いられるが、本実施例では超音
波振動子を用いて超音波エネルギーを発振させて
いる。これにより、突出周条４の該部分が軟化溶
融して表示紙葉６の周端部上面にかぶさり、受縁
３との間でこれを包み込む。この際、超音波によ
る溶融域が突出周条４の上部から内側の部分にな
るように調整することで、溶融した樹脂が蓋枠１
の外周面に流出することを防止させてある（第１
図，）。
この状態で、第２図示のように、蓋枠１を所定
の速度で回転させると、突出周条４の上部及び内
側がその全周にわたつて表示紙葉６の周端部の上
面にかぶさり、これが冷却硬化して蓋枠１と表示
紙葉６とは一体に溶着される。
上記において、蓋枠１の回転速度は使用樹脂の
種類、突出周条の厚みなどによつて適宜に選定さ
れ、また、蓋枠１の回転回数は通常の場合は１回
転で足りるが、必要により数回転させ、そのつど
加熱装置を段階的に押し出して仕上げるようにし
てもよい。
なお、前記加熱装置は本実施例の超音波加熱に
限定されるものではなく、高周波損失の大きい例
えば塩化ビニル樹脂などを用いた場合には、高周
波誘導加熱によつて溶着することもできる。
第３図は本製法によつて得られた蓋の要部の拡
大断面図を示している。これによつて明らかなよ

防水性が高められたものとなる。
〔効果〕
上記のごとく、本発明によれば、蓋枠には単に
表示紙葉を載置すればよいので特別に微細な位置
決めを要せず、また、蓋枠の突出周条に加熱装置
を押し当てつつこの蓋枠を回転させ蓋枠の合成樹
