Abstract: A biodegradable container made of natural fibrous materials includes two shells, each integrally formed and having surfaces which mate with each other to form an enclosure. At least one of the shells includes latching members rotatable about living hinges between a first position, which permits the shells to be coupled to and decoupled from each other, and a second over-center position wherein engagement surfaces of the latching members contact a surface of the other shell to secure the two shells together.

Abstract: Stackable trays for food items are made from fibrous plant material, the source of which may be any fibrous plant or combination of fibrous plants, such as bamboo, wheat straw, bagasse or recycled paper or other paper products. Each tray includes a plurality of locking beads which define recesses. The locking beads and recesses of adjacent identical trays mate with each other when the trays are stacked. Likewise, the locking beads and recesses of two identical trays employed to provide a food container mate with each other to secure the two trays together in a food containment configuration.
