Steel and plastic drums are utilized in many industries for transporting and storing various liquids which may be utilized as fuels, lubricants, ingredients, process fluids, or the like. Often the liquids transported and stored in such drums are highly caustic and/or hazardous and absolute containment during storage, transport, and handling are essential. For example in the semiconductor industry, caustic chemicals such as hydrofluoric acid are commonplace. Some liquids develop significant internal gas pressures when contained during storage. Such pressu...


The invention claimed is: 1. A blow molded plastic drum made by a process comprising the step of blow molding said drum in a single blow molding operation as a one-piece, integrally molded body including a cylindrical wall, a top structure, and a bottom structure, the top structure comprising a top wall, an integral recessed portion, an upwardly extending first fitting adapted to receive a drum insert with a closure, and an upwardly extending chime for protecting the drum insert and closure from physical contact, the chime having a top edge, the top edg...
