摘要： Easy reading of a read code is enabled without matching a read range with a specific print section, and without impairing designability of a cylindrical container and clarity of a display print.
A cylindrical container has, on the outer surface thereof, a print layer. The print layer has an electronic watermark layer including an electronic watermark image printed thereon, and a blindfold layer that renders the electronic watermark image difficult to be visually recognized. The print area of the blindfold layer matches a part or entirety of the print area of the electronic watermark layer.
