A fluid container, such as a pressure vessel, in which a removable closure plug is adapted to sealingly close an open end of a cylindrical vessel. The closure plug is supported relative to the vessel in a manner so that a space is defined between respective surface portions thereof, with a sealing member being disposed in the space. Heat is applied to the vessel to cause movement thereof relative to the closure plug and a compression of said sealing member prior to the final attachment of the closure plug to the vessel.
