Lid featuring ease of use and improved release from a tray or container

A lid adapted for engagement with a container base and easy release therefrom, said container base having a container bottom wall, at least one container sidewall extending upward from said container bottom wall, a lip horizontal section extending outward from said container sidewall, and a lip undercut section extending downward and inward from said lip horizontal section, said lid comprising:

• a lid top;
• a lid engagement feature comprising a rim horizontal section extending outward from said lid top and substantially continuously about a peripheral lid boundary, and a rim undercut section extending downward and inward from said rim horizontal section, said lid engagement feature being configured for mutual cooperation and engagement with the container lip whereby said rim horizontal section rests on said lip horizontal section and said rim undercut section extends downwardly and inwardly, overlying and adjacently parallel to said lip undercut section, thereby forming a base-lid assembly;
• a pair of graspable lift tabs extending from said rim horizontal section in locations that are not directly opposite to each other, said graspable members being configured for simultaneous grasping and flexing by left and right hands of a user;
• and
• first and second press locations cooperative with the lift tabs and located proximally thereto, each of the press locations lying on or inward of said rim horizontal section, such that the user's thumbs can press on the press locations while at least one finger of each of the user's hands simultaneously lifts each of said lift tabs, thereby flexing the rim undercut section outward and away from the lip undercut section and disengaging the lid engagement feature from the container lip at two locations, from which said disengagement propagates around a portion of the peripheral boundary that is sufficient for allowing separation of the base-lid assembly and release of the lid from the container base.
