ABSTRACT:
A sheet plastic dome lid is provided for a generally rigid plastic frozen food receiving tray wherein a finger notch at one corner allows the lid to be flexed upwardly to release one of four locking ribs spaced substantially from the notch but on one side of the tray whereby a smooth camming action releases one locking rib so the others can immediately release the lid from the tray.
