ABSTRACT:
An all-plastic drum construction permits a variety of sizes and capacity of drum by utilizing an extruded tube for the drum side walls of selected diameter and length proportional to the drum capacity desired. An injection molded bottom closure is welded to the bottom end of the tube by a thermoplastic bonding material having dispersed iron particles which are excited when exposed to induction heating thereby facilitating the melting of the thermoplastic. This welding material is disposed within a cavity defined by the bottom closure and bottom end of the tube and when subjected to induction heating and pressure fills the cavity to effectuate the bond between surfaces of the bottom closure and bottom end of the tube. A tight head drum is formed by securing by a similar welding technique a top closure to the upper end of the tube. In forming an open head drum, a thermoplastic chime is initially welded in similar fashion to the upper end of the tube. Thereafter, a top cover is releasably secured to the chime by a locking rim assembly.
