Abstract: Methods of making one-piece lidded containers are described along with containers made by such methods. In one embodiment, the method entails providing a first length of thermoplastic material and a second length of thermoplastic material where a portion of the two lengths of thermoplastic material are brought into an overlapping or abutting orientation to provide a juncture of thermoplastic material. The juncture of thermoplastic material is subsequently secured. The one-piece lidded container is completed by forming a first container and a corresponding lid on the first and second lengths of thermoplastic material. Other embodiments are also described.

Abstract: A container for holding food embossed with a pattern along the sidewall to simulate a woven reed pattern. The container is formed by molding high impact polystyrene, allowing for an inexpensive and lightweight disposable container. Unlike a typical woven reed container, the base and sidewalls are void of openings.

Abstract: Plastic trays used for baking shrink when in an oven such that lids which attached to the tray prior to baking no longer fit the tray after baking. Since the shrinkage of the tray is known for the temperature range expected during baking, a lid having two sets of locking tabs at different perimeters can be used to secure the lid to the tray. The first perimeter and locking tabs are used before the tray is baked and the second perimeter and locking tabs used after the tray baked. In this manner a tray with food therein can have a lid secured thereto before baking when the tray is one size and the same lid secured thereto after baking. The lid is removed during baking and reapplied after baking thus protecting the food in the tray before and after baking. Alternatively the tray may have two lid engaging perimeters for attaching the trays to the lids. The first tray perimeter used before baking and the second after baking. The lid would have one perimeter for engaging the tray before and after baking.
