Container or platter assembly having locking and release features

A container assembly including a polygonal lid and a polygonal container base, the lid being adapted for engagement with and easy release from the container base, the container assembly comprising:

• a container base having a container bottom wall, a container sidewall that extends upwardly and outwardly from said container bottom wall, and a peripheral container rim that is substantially polygonal in shape;
• a lid having a lid top and a lid engagement feature proximal to a peripheral lid rim, said peripheral lid rim being substantially polygonal in shape, said lid engagement feature being configured for mutual cooperation and attachment with the peripheral container rim of the container base, thereby forming a container assembly, the peripheral lid rim including a vertex that is designated as a release vertex;
• at least one graspable member provided in said lid proximal to the release vertex of the peripheral rim, said graspable member being configured for disengaging the release vertex from the peripheral container rim;
• and
• at least one region of enhanced engagement included in each side of the peripheral lid rim and at least one cooperating region of enhanced engagement included in each side of the peripheral container rim, said regions of enhanced engagement in the peripheral lid rim along with said cooperating regions of enhanced engagement in the peripheral container rim collectively ensuring a secure attachment between the container base and the lid, thereby avoiding or impeding unintentional disengagement between the tray and the lid during at least one of handling, transporting, and carrying said container assembly.
