ABSTRACT:
A package of the type having a container with a bottom surface, a peripheral wall, and a peripheral lip includes a lid secured to the peripheral lip. At least one side flap is secured to the lid and is oriented to extend away from the lid toward the bottom surface, and at least one bottom flap is secured to the side flap and to the bottom surface. The side edges of the lid and the side flap define a plane oriented substantially perpendicular to the lid such that the package is stable when resting on the side edges of the lid and the side flap. At least a portion of the side edge of the bottom flap is angled away from this plane toward the bottom surface. The side flap is oriented perpendicular to both the lid and the plane defined by the side edges of the lid and side flap.
