Description
部分は、環状凹部を規定するよう該頂部壁部分と近距離関係に位置付けられた、内方へ延びる環状シールリップを有する。
を有する外側蓋キャップ10を備える。該環状スカート部分は、典型的に、該蓋が取り付けられる組み合わせ容器の雄ねじ形成部とのねじ係合用に、雌ねじ形成部16を有する。蓋除去時、炭酸化中味を有する様な、組み合わせ容器内からのガスの通気を容易にするために、該環状スカート部分14の内面に沿って1つ以上のガス通気溝18が提供されてもよい。該蓋は、該容器からの部分的又は完全な蓋取り外しの視覚的に見分けられる証拠をそれにより提供するために、組み合わせ容器との協力的係合用に、該環状スカート部分から垂れ下がるタンパー指示くすねバンド(示されてない)を有してもよい。
の中央にある時、もう1つのバブル発生機構が生じることが示された。該ペレットが該中央にあると、ライナー材料は該中央から蓋の外側へ半径方向に流れる。該材料がライナースリーブの下を流れる時、流れ先端の形状のために、該材料は該環状シールリップ20の下で空気をトラップする。このトラップされた空気は逃げ道を有さず、45度以上程の、比較的長い距離のシール範囲の周辺付近を延びる。ライナー形成過程の終わりで、成形範囲内の圧力は増加し、トラップされた空気は該ライナーの局所範囲内に圧縮される。この機構は大きな、パス出来ない、気球化バブルに帰着し望ましくない。
Claims (2)
