Abstract
Abstract An egg carton having a pocketed molded paper pulp lower carton body portion and a transparent plastic or synthetic resinous material cover portion is disclosed herein. The lower body portion and cover portion are hingedly connected by the provision of an elongate terminal rib or bead integrally molded on the extremity of one side of the lower body portion and a plurality of channeled projections integrally molded on one side of the cover portion and partially encompassing the elongate rib or bead for pivotal movement thereon. The body portion and cover portion are latched together by an elongate integrally molded grooved projection on the body portion cooperating with a rib or bead terminating a further side of the cover portion to be snapped into the groove of the grooved projection and on the opposite side of the carton from the hinged connection of the body and cover portions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
A carton comprising a body constructed from molded paper pulp, said body including a pair of opposite end and sidewalls, one of said sidewalls having a radially outwardly directed flange terminating in an enlarged bead of a generally circular cross section, said bead being spaced from said one sidewall by said radially outwardly directed flange, a cover constructed from transparent synthetic resinous material, said cover including a pair of opposite end and sidewalls, one of said sidewalls terminating in a free edge overlying said radially outwardly directed flange, a plurality of integrally molded outwardly directed projections carried by said one cover sidewall, said projections being disposed along said bead in spaced relationship to each other, each projection including a channel corresponding in shape to the generally circular cross section of said bead and rotationally receiving said bead for relative pivotal movement of said cover and carton body between open and closed positions, and each projection further including a finger portion projecting inwardly toward said one carton body sidewall beneath said flange and terminating short thereof when said cover is in said closed position thereby limiting the opening movement of said cover to a position at which said finger portion contacts the underside of said flange.
Claim 2
Dependent Claim
