Abstract: A molded plastic overwrap tray is disclosed having a base and sidewalls. The sidewalls are outwardly bowed and connected to one another through integrally formed radius corners. A thick, wide bead is integrally formed to the sidewalls adjacent the open end tray to form a lip for the tray. A plurality of reinforcing ribs also are integrally formed in the corner or junctures connecting the sidewalls to the base. The tray is adapted to be sealed with a tightly stretched overwrap film which exerts compressive forces to provide the tray with relatively straight or slightly bowed upper side edges.

Abstract: This invention relates to an improved package or container made of a rigid cellular foam for protecting fragile articles such as light bulbs during storage or transport and is composed of two hingedly connected housing elements having recesses adapted to enclose said article; holding it in snug engagement within the container and having outer surfaces sloped at each end and polygonal shaped intermediate portions forming ribs providing protection to the contained article in a radial direction, with coplanar flanges extending outwardly from the foregoing recesses in a plane substantially perpendicular to the cross-sectional plane defined by said polygonal ribs.
