A METHOD AND AN APPARATUS FOR INJECTION MOULDING TO MANUFACTURE A PACKAGING CONTAINER

摘要

A method, in a packing and filling machine, of manufacturing a packaging container from a packaging laminate sleeve (10) with at least one inner layer of thermoplastic, the packaging container, in addition to the packaging laminate sleeve, including a shoulder portion connected to the packaging laminate sleeve and a neck portion connected to the shoulder portion, with associated pouring aperture, comprising the steps of: - disposing the packaging laminate sleeve (10) in association with an inner moulding tool, - disposing an outer moulding tool outside the inner moulding tool for forming a cavity between the moulding tools, the cavity having a volume exceeding the volume of the packaging part which is to be injection moulded, - injecting at least one melt of a first material into the cavity, and characterised by the steps of: - disposing the neck portion of the packaging container between said inner and outer moulding tools, in contact with the cavity, - compressing the moulding tools until the melt fills out the cavity and fuses together with the neck and a portion of the inner layer of thermoplastic located at the end of the packaging laminate sleeve, - opening the moulding tools and displacing the packaging container further to additional processing.
