Robust blow moulded plastic tub - with metal and plastic end reinforcements
Реферат: Each end of a polyethylene tub is welded to an outer polyethylene ring of joggled section. A sheet metal profiled section is fixed to each ring so as to grip it firmly. The axially outermost part of the metal section is folded over itself through 180 degrees and projects so that the tub is rolled along this fold when it is handled in service. The construction permits the tub to be blow-moulded with in-turned ends of reduced thickness.
