摘要：
The invention concerns a method which consists in: squeezing a pre-heated plastic film (10) between a mould (100) and a countermould (200); drawing the plastic zone (10a), designed to produce the container base, between a telescopic plunger (117) and a plastic zone (10c) formed between a core (215) and a mobile mould base (115); drawing the plastic zone (10b) designed to produce the container side wall by jointly displacing the core (215) and the mould base (115), while maintaining the plastic squeezed until the final forming position. Then the core (215) and the plunger (117) are withdrawn and air is blown against the inner side walls of the moulding cavity (121) to form the final container, and the container is removed from the mould. The invention is particularly useful for making plastic containers for packaging food products, so as to reduce and make uniform the thickness of the side walls and the base.
