ABSTRACT:
A molded tray having a lid section and a storage section, and a method for its manufacture. The molded tray is especially adapted for the storage and service of food products, such as may be made and sold at take-out restaurants. The device comprises a lid section and a storage section interconnected with a bending, or hinge, section. The hinge section is provided with an area of reduced thickness providing a hinge point, and permitting the lid section to overlie the storage section without significant elastic memory so that the lid remains in the closed position adjacent the storage section. The method comprises the deposition of pulp fibers on a carrier net, with a mask plate positioned to prevent deposition of pulp fiber in the location of the area of reduced thickness.
