摘要
A method of incorporating a pre-cut foil sheet in a container moulded from a thermoplastic material by injection moulding techniques during the process of moulding the container. The foil sheets are fed singly from a store to a position of registry with the free end of the plunger forming part of the mould of the injection moulding apparatus, whereafter the mould is closed, the foil sheet being wrapped around the plunger upon entry thereof into the die. A moulding compound is then injected into the mould. The stream of moulding compound entering the mould is guided so that the foil sheet is either located on the inner surface of the moulded object or on the outer surface thereof.
