Abstract
An egg cell base is provided to create softened areas of egg contact. The base has a center area which creates a softened cushion for egg contact and also creates a gap to shield the eggs from contact with the surface upon which the egg carton rests. Internally, the bottom is provided with a crater construction which helps distribute contact over a larger shell area, and also helps locate and hold the egg tip in place. Surrounding the central area are foot areas of greater thickness which provide strength for stacking. The ring cushion also is capable of providing an accordian motion upward to accommodate high eggs that may bulge the cover of the carton stacked therebelow during shipment.
