Abstract
A carton of a suitable protective flexible plastic or plastic coated material includes a plurality of ovoid cavities for receiving eggs, each cavity having a plurality of communicating channels with tapered sides. The material provides a waterproof base to permit further use of the egg carton as an ice tray. The channels permit water flow between adjacent cavities and provide stress points to facilitate separation and removal of ice cubes formed in the cavities.
