    摘要: The closing method comprises the installing, on the inside rim of the barrel, of a seal having multiple beads and, after filling, the applying of a first hollow lid driven into the barrel down to the level of the seal, then the installing of a conventional flat lid in overlying fashion. The seal can comprise two beads and may assume a U-shape. Application is possible to the transporting of any particularly toxical or radioactive substances.
