摘要： An egg carton structure, particularly designed to package extra large or jumbo grade size eggs and the like, having a bottom section with a plurality of downwardly disposed deep receiving pockets or cells and an interconnected closable cover and locking means. The walls of adjacent cells extend upwardly to form resilient dividers or separators between the cells to prevent contact of eggs reposing in adjacent cells. Variable thicknesses of cell and divider walls, in conjunction with a combination of other unique elements, results in a structure which can be easily thermoformed into a serviceable carton and does not require extensive lateral or transverse ribs, walls or other means to provide lateral support between cells or general stiffness reinforcement of the egg carton as previously considered necessary.
