Claim:
1. A tamper evident container capable of assuming an open arrangement and an initially sealed arrangement, the container comprising: a lid and a base; the lid including a lid rim circumferentially extending about the periphery of the lid and the base including a base rim circumferentially extending about the periphery of the base, the lid rim and the base rim frictionally engaging each other when the container is in the sealed arrangement; a frangible hinge, the hinge being a vertex formed by the convergence of a top pinch segment connecting to a lid rim flange extending from the lid rim and a bottom pinch segment connecting to a base rim flange extending from the base rim; the top pinch segment peripherally projecting from the lid rim and the bottom pinch segment peripherally projecting from the base rim such that when the container is in the initially sealed arrangement: the vertex is vertically situated at a position interposed between the height of the lid rim flange and the height of the base rim flange; and the top pinch segment and the bottom pinch segment have a vertical separation distance between them that extends between a first point on the top pinch segment and a second point on the bottom pinch segment; and the frangible hinge rupturing when the vertical separation distance is reduced.
