Abstract
PURPOSE: To prevent the external appearance of a pillow from being marred, and facilitate deburring, by carrying out a blow-molding process with the use of split dies each having a parting line which is aligned with at least a part of the outer peripheral edge of the end face of a projected flange part of an outer shell of the pillow. CONSTITUTION: When an outer shell 1 of a pillow is to be blow-molded, there is used flow-molding split dies 3 which are designed so as to have each a parting line a part of which passes a part of the outer peripheral edge 5 of the end face of a projected flange 2. Thus, a parting line trace 4 formed by the parting line of the split dies 3 is laid at the side end face of the outer shell 1 of the pillow, and accordingly, the parting line trace 4 is aligned with a part of the angular outer peripheral edge 5 of the end face of the projected flange. Accordingly, the parting line trace 4 is formed following the outer peripheral edge 5 so as to be indistinguishable. Further, burrs 7 on the parting line trance 4 are projected with a height difference between itself and the side end face of the outer shell 1, and accordingly, can be simply removed.
