A plastic container capable of assuming a loading state, an initially sealed state and an opened state comprises a lid including a lid rim and a base having a base rim. The lid rim sealingly engages with the base rim. A projecting portion has an accordiated section and a pull tab that projects outwardly from the lid. The accordiated section has at least one pleat. The projecting portion includes a frangible bridge. When the plastic food container is in the initially sealed state, the accordiated section has a first length and a first orientation relative to the projecting portion. When the container is in the initially sealed state and a first pulling force is applied to the pull tab, the frangible bridge ruptures. When the frangible bridge ruptures and before the lid is separated from the base, the container is in a tab-employed state in which the accordiated section springs outward and has a second length visibly longer than the first length.

Tamper evident food container with accordiated pull tab

A tamper-evident container comprises a lid and a base. The lid includes a lid rim. The base includes a base rim. A frangible hinge is formed between a lid hinge segment extending outwardly from the lid rim and a base hinge segment extending outwardly from the base rim. The lid hinge segment includes at least one thumb rest that is positioned, sized and shaped to receive the thumb on a user's hand. The thumb rest has a counterpart finger rest located on the base hinge segment that is positioned, sized and shaped to receive a finger on the user's hand while the thumb of the same hand is in contact with the thumb rest. The frangible hinge is configured to rupture when the container is in the initially sealed arrangement by the application of a pushing force to the thumb rest and a contemporaneous pulling force to the finger rest.
