The tamper evident container includes a base with a base hinge panel and a lid with a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.
