A lid for a container including a closure surface, a circumferential rim extending about a periphery of the closure surface with the rim including an outer side wall, an inner side wall and a transition wall interconnecting the outer side wall and the inner side wall with the closure surface extending from the inner side wall and at least one cut out formed in at least one of the inner side wall, the outer side wall and the transition wall such that a portion of a brim of the container is visible through the cut out when the lid is properly positioned on the container. A method and apparatus for forming such lid includes providing a substantially planar blank from which the lid is to be formed, providing at least one forming die having a surface configuration conforming to a predetermined configuration of the lid, positioning the blank adjacent the forming die, conforming the blank to the configuration of the die and forming at least one cut out section in the rim of the lid wherein at least a portion of an associated container is visible through the cut out when the lid is positioned on the associated container. The apparatus having at least one forming die having a surface configuration conforming to the configuration of the lid, forming device for conforming a blank to the surface of the forming die and a cut out forming device for forming at least one cut out in the circumferential rim of the lid in a manner such that at least a portion of an associated container is visible through the cut out when the lid is positioned on the associated container. |
