Tri-fold egg carton for various size jumbo eggs

A molded article comprising a tri-fold plastic egg carton integrally formed from a sheet of molded plastic material, the egg carton comprising:

• a base and a cover hingedly connected to one edge of the base for pivoting between open and closed positions, the base and the cover having respective peripheral edges that mate with each other in the closed position, and each of the base and the cover having a complimentary 2×6 matrix of cells that, when the cover is closed over the base, the cells of the cover and base are aligned and form a 2×6 matrix of cell pockets for holding individual eggs,
• each cell having a bottom wall and a sidewall extending upwardly from the bottom wall to form a corresponding one of the cells,
• a cell post formed at an intersection of four adjacent cells as an extension of the sidewalls of the four adjacent cells and having a central mating surface, wherein when the cover is in the closed position over the base the central mating surfaces of the cell posts of the base and cover mate with one another,
• a lid hingedly connected to another edge of the base for pivoting between open and closed positions, wherein when the cover and base are in the closed position the lid can be closed over the cover to form an assembled carton;
• each cell pocket having an arcuate, outwardly bowed sidewall portion sized to hold any different size variations of a jumbo egg, of from 2.50 to 3.00 ounces per egg, in an oriented or a non-oriented direction in the base cell;
• the bottom wall of each base cell and cover cell comprising:
• a lowermost peripheral standing ring defining a base plane;
• and
• a recessed wall portion disposed radially inwardly from the peripheral standing ring and defining a central recessed area above the base plane, the recessed wall portion including a central dome in a concave out position in a relaxed state, a first circumferential hinge disposed radially outwardly of and surrounding the central dome, and a second circumferential hinge disposed radially outwardly of and surrounding the first hinge, the first and second hinges as molded being in a contracted position in a relaxed state, wherein each of the first and second hinges are movable, expanding in a height direction transverse to the base plane, between their contracted position to one or more extended positions to move the central dome up and down in the central recessed area while remaining above the base plane while the central domes of the base cell and cover cell engage opposing ends of a jumbo egg of the different size variations and orientations.
