THIS INVENTION RELATES TO A CYLINDRICAL, BOW-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) AS 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.
