PURPOSE:To contrive to be able to cool a parison effectively and uniformly in short time by a method in which cooling air is uniformly supplied through porous member from both sides of inner surface and outer surface of a parison, and moreover the cooling is begun since immediately after the parison has been taken out. CONSTITUTION:An air chamber 25 is provided under a parison receiving plate 22. The air chamber 25 has the first chamber 26 into which the parison 24 is inserted, and the second chamber 28 at the outer periphery of the first chamber 26. The first chamber 26 and the second chamber 28 are partitioned with the cylindrical barrier 30 permeable by air which is made of porous member. An air vent 31 is provided in the first chamber 26, and air feeding inlet 32 is arranged in the second chamber 28. The air temperature-regulated by a fan 34 through an air temperature regulating device 36, may be supplied to the air feeding inlet 32 by way of flexible hose 33. The fan 34, the air temperature regulating device 36 and the flexible hose 33 constitute a cooling air feeding device. |
