Abstract
Tri-fold egg carton has a base and a cover each having a complementary matrix of egg receiving cells such that, when the cover is assembled on top of the base, the complementary cells encapsulate each egg in an individual cell pocket (see FIGS. 3-5). Each base cell and cover cell includes a central dome and first and second radially spaced apart circumferential hinges that surround the central dome, and lie radially inward of a lowermost standing ring, enabling the dome to move up and down above the plane of the standing ring (in the height direction of the closed carton) between multiple positions to accommodate jumbo eggs of varying dimensions (height and width) to hold them securely in their respective cell pocket. The base and cover further include full height cell posts with mating surfaces that engage in the assembled state. The carton further includes a lid which fits over the cover (of the assembled cover and base), in a secure and locked position.
