Abstract

A small case with partitions, e.g. for tools, is blow moulded at the exit from the die to obtain in one piece the base and the top joined by a hinge formed of a film of plastics material with dimensions determined by an interval which, in the mould, separates two pre-shaped pieces which are welded together by a heating element on leaving the die. The moulded shape has projections, depressions and location points on the free edges which make possible the attachment of a handle and which are capable of pivoting with respect to the case to form a lock.
