Abstract
A composite lid formed of plastic resin and paperboard is disclosed along with a method of making the lid. The lid has a primary panel of paperboard defining its center and a plurality of secondary panels, also of paperboard, continuously attached to the perimeter of the primary panel and oriented perpendicularly to its plane. A skirt of plastic resin is attached to the inside surfaces of the secondary panels, the secondary panels being in edge abutting relationship and totally covering the skirt. The primary and secondary panels thus form a lid having a continuous outer surface capable of receiving a print media, the continuous outer surface extending entirely over the lid. A bar of resin is provided around the inside surface of the primary panel and resin spokes connect the bar to the skirt. Raised segments are positioned intermittently around the inside surface of the skirt, the segments engaging a container to hold the lid in place. Sealing ribs are also formed on the inside surface of the skirt which engage the container and provide a seal between it and the container. The method of making the lid includes the steps of providing the primary and secondary panels, folding the secondary panels to form inside surfaces of the lid and injecting resin onto the inside surfaces to form the skirt.
