Abstract
The invention relates to the thermal treatment of the body (2) of a preform (1) or of an intermediate container made of a thermoplastic material during a process for manufacture of the container, such as a flask or bottle, in particular by blowing or stretching-blowing, the entirety of the body (2) of the preform being heated to a temperature greater than the softening temperature of the material, at least one longitudinal portion (13) of the body (2) of the preform in rotation on itself being heated to a temperature greater than that of the rest (14) of the body, thereby making it possible to produce a finished container incorporating a body having a complex shape.
