A spigot is formed at the container wall for the screw joint, which protrudes into a corresponding opening in the ballast weight. A rotary hollow chamber is stayed between the spigot and the opening. A rotary, elastic element is inserted in the hollow chamber between the spigot and the opening, which fills the hollow chamber sectionally.</p> |
