A newly filed patent (Publication Number: US20240002108A1) describes a one-piece paper lid for containers. The lid includes a base with a central and peripheral portion, a circumferential bead that can extend radially inwards or outwards, and a skirt with an outer sidewall, inner sidewall, and upwardly extending curl. When the circumferential bead is in the outward position, the skirt's diameter changes, and the height of the bead decreases by 20-60%. The lid is designed to have minimal flex when the bead is in the outward position, and the inner protrusion on the inner sidewall is continuous.

The patent also details a method for making the paper-based lid, involving deep drawing the blank with a device, forming the circumferential bead, folding the skirt to create the upwardly extending curl, knurling the skirt, and forming the inner protrusion. The process includes compressing the deep drawn blank into a mold to form the bead and applying different pressures to create the inner protrusion. The method ensures that the lid is made from at least 95% paper material, highlighting its eco-friendly design. Overall, the patent aims to provide a unique and efficient paper lid solution for containers, emphasizing ease of manufacturing and environmental sustainability.
