PROBLEM TO BE SOLVED: To provide a blow molded container which prevents bottom cracking on a bottom pinch part in relation to the blow molded container obtained by blow-molding multilayer parison in split molds.SOLUTION: A cross section of multilayer parison 20 is deformed from a cylindrical shape to a cross shape by bottom part split molds 11, at the same time, the pinching-off is performed such that a first pinch part 7 and a second pinch part 8 are molded on the bottom of the container in a form of intersecting each other and, thereby, the path of an adhesion belt 6 is shifted to the inner side to make the central position of the first pinch part 7 pass through. |
