PURPOSE:To improve the quality and yield of a product by performing the temp. control of the outer cylinder and inner cylinder by burying a temp. sensor and heater inside the container outer cylinder and by jetting a cooling water and air on the container inner surface after the extrusion. CONSTITUTION:A heater 8 is set up on the container main body 1 and the upper part heater 9 and lower part heater 10 are buried by dividing them at the inner part of an outer cylinder 2 as well. Moreover, the temp. control and the maintenance of an inner cylinder 3 are performed by burying temp. sensors 4, 5 respectively on the part close to the inner cylinder 3 of the outer cylinder 2. Then, the inner surface is cooled and at the same time the cooling water is expelled by the air, by jetting the air together with the cooling water on the inner surface of the inner cylinder 3 by providing the water jet nozzle 6 and air nozzle 7 for cooling the inner surface of the inner cylinder 3 after product extrusion. In this way, the thickness deviation of the product is prevented because of the temp. uniformalization inside the container being secured. Consequently, the quality and yield of the product are improved.
