Abstract
An improved package is provided which is formed from a blank of rigid material, such as cardboard, and an internal lining of plastic material, with the rigid blank including a bottom wall and a plurality of side walls. The internal lining extends over the top edge of the side walls and along the exterior walls of the package to define an exterior lining. The free edge of the exterior lining includes a flange extending in a direction outwardly from the side walls of the package. In addition, extension flaps of one package are operable to act as a stop and engage a portion of another package nested therewith to prevent the nested packages from being wedged within each other.
