ABSTRACT:
A plastic drum assembly includes a preformed insert fused to at least a portion of the corner of the drum. In order to facilitate lifting and handling the drum, the insert is formed with a pair of indentations on opposite sides of a ridge. The method involves placing the preformed plastic insert across at least a portion of a corner of a mold cavity and blow molding the drum in the cavity to form the drum and fuse the drum corner to the insert. The disclosure also is concerned with methods for forming indentations in a blow molded plastic drum and with a method of reinforcing the corner of a blow molded drum.
