Abstract

The invention concerns a method for making by compression moulding plastic parts having a neck provided with a dispensing orifice comprising a first step which consists in producing a plastic blank (820) and a second step which consists in compressing said blank, wherein the moulding cavities are so designed that said neck, once moulded, has a summital wall including a cleavable zone with a notch whereof the outline delimits the desired shape for the orifice. The notch has a typically U-shaped or V-shaped cross-section, oriented in a direction substantially parallel to the neck axis. The neck, at least at the cleavable zone, is shaped by compression moulding of said blank between a first rigid mobile part (835) and a second mobile part (830+805), less rigid than the first mobile part, for example made of plastic material. Preferably, the neck is overmoulded directly on the cap which is designed to close the orifice.
