Abstract:

Transparent egg cartons suitable for being made from a variety of transparent polymeric materials and particularly from polylactic acid or other biodegradable polymers are described. The egg cartons use a “W” shaped hinge or box hinge element for hingedly connecting the lid to the tray or a flap to the tray. The flap is made with lattice struts to increase the lateral strength thereof, and contains at least three button tabs for interlocking the flap with the lid. The lateral most button tabs are located about ⅛the length of the flap from the ends of the flap. The egg cartons have an awning portion that extends from the front surface of the lid to cover the “W” shaped hinge or box hinge when the lid is closed. A space is provided between the edge of the awning and the hinge for a consumer to place a finger for disengaging the lid from the flap.
