PROBLEM TO BE SOLVED: To achieve both rigidity as the whole of a container and squeezing by pressing in a bottle-shaped container which is molded by blow molding and used as a container body of a squeeze container.SOLUTION: In a bottle-shaped container obtained by biaxial-stretching blow molding a test tube-like preform, a vertical strip-like part which is formed of a transparent synthetic resin and penetrates a peripheral wall including a trunk part is formed in a vertical strip shape in the peripheral wall, a main peripheral wall part, which is a peripheral wall part excluding the vertical strip-like part, is formed of a colored resin prepared by coloring the transparent synthetic resin, and the vertical strip-like part is drawn in a peripheral direction by a biaxial-stretching blow molding step with magnification higher than that of the main peripheral wall part to form a thinned region. |
