ABSTRACT:
To produce a laminated container consisting mainly of thermoplastic materials, an outer container element consisting of material having desired barrier properties is first vacuum moulded from thin foil or film material in a vacuum mould, and thereafter an inner container element is blow moulded in the same mould with the outer container element present therein. To carry out this method, a mould is provided which consists mainly of two vacuum mould halves which are closable upon an intermediary plate in the vacuum moulding step and directly closable upon one another in the blow moulding step.
