This invention relates to a cylindrical, blow-molded lidded barrel (wide-mouthed drum) with a barrel lid and tension-ring closure. Previously known lidded barrels have comparatively little ability to withstand falls and are therefore not well-suited for handling liquids. Owing to the special configuration of the barrel lid and the barrel mouth edges as well as by a special matching of the individual components to one another, the lidded barrel according to the invention can be manipulated in the filled state with the same barrel-gripping tool (parrot's beak), ans is universally employed and in industrial use for modern plastic L-ring bung barrels or normal steel bung barrels. By improving the strength of the lidded barrel when it is dropped, the barrel is also made especially well-suited for handling liquids since it remains liquidtight even when dumped or dropped from great heights.
