ABSTRACT:
A tray-lid assembly comprises a tray and a lid. The tray includes a bottom panel, a continuous wall panel, and a continuous rim. The continuous wall panel encompasses the bottom panel and extends upwardly from the bottom panel. The continuous rim encompasses an upper edge of the continuous wall panel and projects laterally outwardly therefrom. The lid includes an upper surface and a lower surface. The lower surface of the lid is detachably connected to the continuous rim. The lid has a first inside cut score formed in the lower surface of the lid. The lid has an outside cut score formed in the upper surface of the lid. The outside cut score bridges the periphery of the lid at two points to divide the lid into a main section and a relatively small corner tab. The first inside cut score and the outside cut score are generally parallel and in proximity to each other. The first inside cut score and the outside cut score form a rev cut such that the lid delaminates in a first delamination region between the first inside cut score and the outside cut score in response to pressing down on the corner tab. Additional inside cut scores are preferably provided to facilitate removal of the corner tab from the tray.
