Plastic chime overlay for fibre drum

In a storage drum adapted to contain aggressive materials, said drum including a peripheral side wall with an upper edge portion defining an open upper end adapted to selectively receive an overlying cover, and a closed bottom, an inner lining within said drum, said lining being generally inert to aggressive materials to be contained within said drum, a chime overlying, intimately engaging and defining a bead about the upper edge portion of the side wall peripherally thereabout, said chime conforming to the upper edge portion both interiorly and exteriorly of said drum;

• the improvement comprising a plastic overlay generally inert to aggressive materials to be contained in said drum, said overlay overlying said chime peripherally about said open upper end and depending for at least a portion of the height of said chime exteriorly of said drum, said overlay depending below said chime interiorly of said drum and terminating in an inner edge portion engaging said lining below said chime, a continuous bond between said overlay inner edge portion and said lining sealing said overlay to said lining peripherally about said open upper end of said drum, said overlay having a continuous inner surface, and an uninterrupted bond between said chime and said inner surface of said overlay for substantially the full extent of said inner surface, said uninterrupted bond providing a continuous seal between said overlay and said chime for the extent of the uninterrupted bond between said overlay inner surface and said chime.
