PROBLEM TO BE SOLVED: To provide a blow molded article which can be finished without performing afterprocessing for removing burrs even when the burrs are generated on a parting line. SOLUTION: A recessed part 14 is formed by using a parting line 13 related to blow molding as a side edge and in addition, a projected part 15 is formed continuously to the recessed part so as to expanding another side edge of the recessed part 14 outside of the position of the parting line. It is possible thereby to hold value of a commodity product and to finish without afterprocessing for removing burrs and to attempt to save labor and to perform cost reduction. |
