摘要
A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.
