PROBLEM TO BE SOLVED: To provide a container and a method for its manufacture, the container being of a simple make, enabling a reduction in cost, having good pressure resistance against a high internal pressure that pressurizing gas filling the container may have, and, with no defect in the sealed state, having a high reliability in stability of quality. SOLUTION: A container 1 has a hole part 10 in a constitution for holding a material with the inside 7 in a pressurized state and the container, when disposed of as waste, is relieved of the pressure by destroying a sealing material 4 which seals the hole part 10. The sealing material 4 covers the hole 10 and its bordering part 16 from the inside 7 of the container and forms a protrusion rising toward the inside 7 of the container. This protrusion of the sealing material 4 has a curved surface with the apex virtualy at the center of the hole 10. |
