Abstract
Abstract An egg carton, having two rows of cavities of six each, that has the individual cavities separated from each other longitudinally and transversely by a combination of transversely and longitudinally extending walls, the walls having sloping sides and meeting at a point intermediate the depth of the cavities to provide for easy egg removal. In addition to the wall separator members, the cellular bottom portion of the carton is further characterized by having a number of upwardly projecting tips to provide for individual egg separation.
