Abstract
A container with a base (12) and lid (14), clearly indicates if the lid has been opened after a clerk loaded food into the base and closed the lid. The base and lid each has a respective lid tab and a base tab, with one tab forming a slot (26) and the tab other projecting through the slot, and with the base tab forming a barrier wall (80) that lies over the lid tab. One of the tabs has a weakened severable line (90, 92) that can be torn to allow the lid tab to be lifted to open the container.
