Abstract
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.
