A carton erected from carton material in cut and scored blank form, the carton comprising a lower tray structure comprising a bottom wall having flap connected tray side walls folded upwardly from the bottom wall, and an easy-open easy-close cover structure having a top wall having flap connected cover side walls folded from the bottom wall including a corner wall extending from the top wall between two adjacent spaced apart end edges of two adjacent cover side walls within a plane extending at an angle with respect to the angularly related planes of the two adjacent cover side walls. The cover structure is retained in closed relation by an opening formed in the corner wall and tabs formed from a portion of carton material defining the tray structure at the interconnection of the two adjacent tray side walls. The corner wall includes a portion of carton material extending downwardly and outwardly from the opening in a position to be interengaged during the closing movement with the tabs such that a relative one carton material deflection takes place by virtue of the interengagement and is freed with a snap action when the cover structure reaches its closed position enabling the tabs to extend upwardly and outwardly through the opening.
