ABSTRACT:
An interlocking carton and lid combination is disclosed for storage of ice cream, frozen yogurt and the like. The interlocking combination includes a rectangular container provided with flaps integrally formed therewith and attached along the upper edges of the container sides. The flaps are folded along a crease inwardly into the container and glued along a strip portion to the side walls. A slit is provided in each of two opposed sides on the exterior thereof, the slits being formed in the side walls at a position adjacent the flaps and located below the crease and above the glue strip adhesively coupling the flap to the side wall. This positioning of the slit with respect to the crease and glue strip cause the unglued portion of the flap to bow outwardly. A lid having a central portion is provided with transversely extending flanges attached along the peripheral edges of the central portion and integrally formed therewith. The flanges include an outer side and an inner flap portion connected along a crease. Two opposed flanges have slits located in the respective flap portions and the flaps are glued to the respective outer sides along a strip portion located between the slit and the edge of the flange spaced from the crease. This configuration causes the unglued portion of the flap between the crease and the slit to bow outwardly. The lid is receivable on the container wherein the lid slits interfere with the container side slits.
