PROBLEM TO BE SOLVED: To form a pinch part having excellent sealing performance by sufficiently pressing in adhered part in a width direction of an inner layer parison to a sealed state at both end corners of the width direction of an inner surface of the pinch part of the parison. SOLUTION: In the method for molding a hollow molded parison, a pinch part 16b of an inner layer parison 16 has a cut part 16a formed by cutting an overall width of a lower end of the parison 16 by a cutting edge of a pinch blade, an adhered part 16d connected in a strip-like state to the cut part 16a, pressed by a dam connected to the edge and brought into close contact in a thickness reduced state, and a protrusion 16e having a thickness protruded by pressed by the dam. In this case, the protrusion 16e is formed in the overall width of the inner surface of the pinch part 16b of the parison 16. |
