Abstract

PURPOSE:To obtain at a lower cost a formed product having a double wall surface structure, by forming a wall structure wherein the outer wall part and inner wall part are monolithically and successively formed with intervening turned edge parts, and folding the inner wall material into the inside of the outer wall material at the turned edge parts. CONSTITUTION:An approximately square plane shaped outer wall material 1 is formed with a body material 4 and bottom material 5 thereof are blow-formed, and an inner wall material 2 is formed monolithically and successively thereto with turned edge parts 6, to form an envelopelike wall surface materials 7 made of flexible plastic resins. Then the bottom material 5 of the inner wall material 2 of the wall surface material 7 is extruded and folded at the turned edge parts 6 to fold the inner wall material 2 inside the outer wall material 1 to form a box body. Thereafter, the outer wall material 1 of the wall surface material 7 is inserted in an outer die A, while the inner die B is placed inside the inner wall material 2. Then by inserting an outlet port C' to an intake 8 and injecting the liquids raw material 10 for expanded heat-insulating materials 3 into a hollow space 9 to form a heatinsulating box body by heating and expanding.
