この梁１０は、容器口部１に設けられているアルミ箔等
の金属箔シール１００の上側に位置しており、且つ該シ
ール１００に対して上に凸となる様に湾曲している。This beam 10 is located above a metal foil seal 100 such as aluminum foil provided on the container opening 1, and is curved so as to be convex upward with respect to the seal 100.
該梁１０は、撓みやすい様に薄肉となっており、例えば
可撓性を有している限り、ポリプロピレン等の剛性プラ
スチック材料で形成されていてもよいし、或いはポリエ
チレンエラストマー、軟質塩ビ等の柔軟性のプラスチッ
クで形成されていてもよい。The beam 10 has a thin wall so that it can be easily bent, and may be made of a rigid plastic material such as polypropylene as long as it has flexibility, or a flexible material such as polyethylene elastomer or soft PVC. It may be made of plastic.
上述した梁１０は、通常複数個設けられており、これら
の梁１０の中央交差部分には、シール押し破り用突起１
１が設けられる。The above-mentioned beams 10 are usually provided in plural numbers, and a seal push-breaking protrusion 1 is provided at the center intersection of these beams 10.
