Abstract
A manufacturing method of a resin container having a light-transmitting region and a non-light-transmitting region extending in an axial direction includes: a first injection molding step of injection-molding a first layer of a preform having a convex portion extending in the axial direction using a first resin material having a light-transmitting property; a second injection molding step of injecting a colored second resin material on a surface side on which the convex portion of the first layer is formed and laminating a colored second layer in a region excluding the convex portion of the first layer while exposing the convex portion in the axial direction; and a blow molding step of blow-molding the preform in a state of having residual heat from injection molding.
