A process for the production of hollow articles from preforms of a thermoplastic material, one open end of which preforms has a neck moulded at least partially into its definitive shape. During the final blowing operation, the region corresponding to the moulded part of the preform is isolated from the remainder of the interior of the preform. The isolated region is cooled by sweeping with a cooling fluid.
