Abstract
A device and method for producing labeled expanded resin containers; the method including applying a label sheet, formed from a label material capable of maintaining an electrostatic charge, to an inner wall of female portions of two-part molds, positioning one or more male portions of the two-part molds in contact with the corresponding female portions to form one or more mold cavities; adding expandable resin beads or pre-expanded resin beads to the mold cavities; applying a sufficient amount of heat for a sufficient length of time to the mold cavities to effect expansion of the expandable resin beads or pre-expanded resin beads to form labeled containers; cooling the labeled containers; and removing the labeled containers from the mold cavities. The labels on the external wall of the labeled containers present a smooth circumferential surface.
