底部３は第４ａ図、第４ｂ図に一層詳しく示され、その
中後の図は前記底部の製法を示す。
この底部は熱成形又は他の方法たとえば中央部１の中に
延びる部分３ｂと中央部１の底縁１ｆを囲む枠部３ｃと

第６図、第７図は、第１図に参照数字４で示した口あけ

この口あけ装置は２個の引裂き切込み（それぞれ４ａ，
４ｂ）から成り、その内引裂き切込み４ａは出来るあけ
口を画定し、一方４ｂは本例では完全に引裂き切込み４

４ｂで形成した握り舌４ｄを容易に握ることができるで
あろう。これは握り舌４ｄが厚く作られかつつめの縁す
なわち握り縁１１を有することでさらに容易にされる。
握り舌４ｄは同じく厚い材料で作られる熊手４ｅに延び
ている。このようにして前記握り舌が第６図、第７図に
示す位置から上方に引上げられるとき前記熊手は容易に
内方プラスチツク層９に穴をあけることができる。この

易になる。引裂き切込み４ａ，４ｂは内方プラスチツク
層１０まで延びるか又は多少浅く作られるかいずれでも
よい。いずれの場合も射出成形材料の流れを容易にする
ため外方引裂き切込み４ａを１個所４ａ１以上で中断す

これは密に配列された円板２６によつてなされ、円板の

（１）中央部１の胴を通り、容器の中味がその内側およ

できていないので、容器の外側からも内側からも、継目

（５）中央部１とふた部２との接合面および中央部１と
底部３との接合面の密封性能が、中央部が継目のある層

（９）印刷によつて中央部１の箔に加えられる力を支持
する力が、継目のある層だけで構成されている場合より
も大きくなり、また横方向への伸びによつて中央部１の
強度が増大するので、積層後、箔に印刷する場合に、印
刷を妨げる要因が少ないこと。
