Abstract: An egg carton incorporating an easy-open latching feature comprising an outwardly extending protuberance on the carton locking flap which extends into a cutout section at the bottom edge of the cover front wall. By depressing the protuberance, the carton latching mechanism is disengaged permitting convenient, one-handed opening of the carton. There is also provided an improved latching mechanism wherein the bottom surface of each locking lug is planar and horizontally oriented when the carton is closed.
