METHOD FOR PRODUCING A CONTAINER BY BLOWING IN WHICH THE DEPRESSURIZED BLOWING GAS IS DIRECTED TOWARD A HOT ACCESSORY FOR COOLING THE LATTER BY VENTILATION

摘要

The invention relates to a device (10) for producing containers (12) made of a thermoplastic material by blowing a preform (14), the device (10) comprising: a molding cavity (18) which is to receive a preform (14); a blowing nozzle (24) capable of injecting a compressed gas into the preform (14); an exhaust pipe (32) which connects the nozzle (24) to an end outlet (34) to the atmosphere, and in which the compressed gas is depressurized to the atmospheric pressure such that the gas stream exiting the outlet (34) is cold; and an accessory (44) comprising a heat source, characterized in that the outlet (34) is arranged near the hot accessory (44) such that at least a portion of the cold gas stream is directed toward the hot accessory (44) in order to cool the accessory (44) by ventilation.
