Abstract
A food container formed from plastic, can be loaded with food and then closed by a clerk, and thereafter cannot be opened without tearing apart first sides (24, 26) of the base (12) and lid (16). The container is formed by a single sheet of plastic that forms a base and lid with second sides (20, 22) that are latched together and with adjacent first sides that are joined by a joint line (30) in the plastic that is creased and that has slits (40). At the joint line, the lid has a projecting lid tab (32) and the base has a projecting base tab (36). A person grasps both tabs, and lifts only the lid tab to tear apart the first sides of the base and lid along the joint line (30). Thereafter, the lid can be easily closed and reopened on the base.
