Abstract (en)
[origin: WO2014064041A1] The invention relates to a method for forming a container (10C) from a preform (10A) by stretch-blowing, said method comprising: a first step (E1) of positioning the preform (10A) on a fixed support (26); a second step (E2) of freely expanding the preform (10A) by stretch-blowing, the preform (10A) being thereby shaped into an intermediate container (10B) in the form of a bubble; and a third, shaping step (E3) wherein at least one first part (50, 52) of the deformed wall of the preform (10A) comes into contact with at least one moulding surface (44, 46). The invention is characterised in that a second part (54) of the deformed wall of the intermediate container (10B) does not come into contact with any of the moulding surfaces until the final cooling of the container (10C) below the glass transition temperature (Tg) thereof.
