To provide a sealed vessel such as a super-pressure balloon that can be constituted of an inexpensive material, does not require checking of the presence of micro-holes, and is capable of attaining high air tightness or liquid tightness.SOLUTION: A super-pressure balloon (SPB) 1 is constituted of a multilayer structure including an inner layer frame 10 and an outer layer film 20. In the super-pressure balloon 1 in an expanded state, a pressure of gas on the inside 11 of the inner layer film 10 is higher than a pressure outside of the outer layer film 20. In the super-pressure balloon 1, a flow path between the films 10, 20 is regulated by making the pressure of the gas on the inside 11 of the inner layer film 10 higher the pressure on the outside of the outer layer film 20.SELECTED DRAWING: Figure 2

    【課題】安価な材料で構成でき、微小な穴の存在の確認も不要で、高い気密性又は液密性を達成できるスーパープレッシャー気球などの密閉容器を提供すること。【解決手段】スーパープレッシャー気球(SPB)1は、内層フィルム10及び外層フィルム20からなる多層構造により構成される。展開した状態のスーパープレッシャー気球1では、内層フィルム10の内部11の気体の圧力は、外層フィルム20の外部の圧力よりも高くなる。スーパープレッシャー気球1では、内層フィルム10の内部11の気体の圧力を外層フィルム20の外部の圧力よりも高めることで、フィルム10、20間の流路が規制される。【選択図】図2
