Title:
METHOD FOR MANUFACTURING RESIN CONTAINER AND BLOW MOLDING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/189723
Kind Code:
A1
Abstract:
This method for manufacturing a resin container has a temperature adjustment step in which a preform is accommodated in a cavity mold, a coolant introducing member having a first flow passage and a second flow passage which have mutually different positions for introducing or discharging a coolant is inserted into the perform, and the preform is cooled by being brought into close contact with an inner wall of the cavity mold by the pressure of the coolant introduced from the coolant introducing member. When cooling the preform, the cooling is performed by switching a first cooling blow that introduces the coolant from the first flow passage and discharges the coolant from the second flow passage, and a second cooling blow that introduces the coolant from the second flow passage and discharges the coolant from the first flow passage.
