ABSTRACT:
In a cup formed container formed from a plain punched blank of cardboard or the like laminated with an inner lining blank, the carton is formed by two opposite side pieces folded up from the bottom of the blank so as to form two opposite walls, the remaining two walls being formed by extended ends of the two side pieces and a joint flap, the joint flap being folded upwardly from the bottom, and the extended ends being folded upwardly and inwardly so as to lie adjacent the joint flaps. Two cooperating extended ends and a joint flap thus form the other walls, with the cooperating extended ends forming a joint between their opposing joining edges. The lining blank projects a distance radially outside the joint flaps and above the intended upper edge of the container, the projecting portion of the lining blank forming a projecting lining tongue which is folded over the upper edge of the walls and is attached to the outside of the container over the joint formed by the joining edges of the extended ends. Any gap between these joining edges thus is bridged over at least part of its height by the joining flap, and over at least part of its height by the folded lining tongue, which lies between the extended ends and the associated joint flap. This construction eliminates the tendency of the walls formed by the extended ends to buckle outwardly because of the weakness inherent in a wall formed by the two unconnected extended ends, particularly in the area of their joining edges.
