ABSTRACT:
A reinforced end sealed container is prepared from a singe blank of paperboard that is symmetrically cut and scored to provide a bottom panel, foldably attached side and end wall panels, a pair of top closure flaps and a plurality of corner connecting panels, the improvement wherein the top closure flaps are also provided with integral end seal flaps and the end walls are provided with T-tabs, which, together with a notched portion of at least one of said top closure flaps, produces a container with superior end sealing strength. The notched portion of at least one of the top closure flaps serves as a reinforcing compression column between the T-tabs to provide increased resistance to any damage the container or its contents might suffer when the container is sealed closed.
