Abstract
A synthetic resin container or bottle with a window obtained by subjecting a test tube-shaped preform made by injection molding to biaxial stretch blow molding is provided. The container includes a transparent base layer; a circumferential wall formed of the transparent base layer; and a light-blocking or opaque intermediate layer formed in the base layer in a laminated manner to cover an area of a predetermined height of the circumferential wall. The intermediate layer is formed in a laminated manner over an area covering an entire circumference of the circumferential wall excluding a non-laminated section, where the intermediate layer is not formed, that extends in a shape of a longitudinal strip along the central axis direction of the container on the circumferential wall of the container. The non-laminated section serves as a window section.
