Filed:

Aug 16, 2000

Appl. No.:

09/639594

Inventors:

Richard L. Ramirez - Lawrenceville GA
Mark A. Bergeron - Lithonia GA

Assignee:

Tekni-Plex, Inc. - Somerville NJ

International Classification:

B65D 136

US Classification:

206564, D7555, 220575, 229407

Abstract:

A food serving tray, preferably of polystyrene foam, is provided having a base and bounding side walls. The base is formed with at least two bottom walls and at least one partition interposed therebetween. To provide enhanced stability and rigidity to the tray, protrusions, preferably step-shaped, are formed in the side walls located between the crests of the partitions and the top edges of the side walls. The protrusions provide changes in direction in the side walls which enhance the strength and rigidity of the tray. In addition, the bottom walls may be dished concavely so as to have portions extend upwardly. Under loading, the dished bottom walls become flattened and bi-axially stressed to further enhance the overall strength and stability of the tray.

Assignee:

Tekni-Plex, Inc. - Somerville NJ

International Classification:

B65D021/32

US Classification:

220675

Abstract:

A packaging container is integrally formed from plastic foam material, such as extruded polystyrene foam. The packaging container has a base, four sidewalls extending from the base, and four corners, each extending between a pair of adjacent sidewalls. The sidewalls have substantially rectangular protrusions extending from the base to a top edge to strengthen the sidewalls against lateral forces. The sidewalls may also have rounded ribs which protrude into the interior of the packaging container for further reinforcement.
