1. A tamper evident container, comprising:
a base having a substantially horizontal bottom joined at a perimeter thereof to a lower edge of at least one substantially vertical base wall, the base comprising a substantially horizontal base flange extending outwardly from an upper rim of the base;
a lid that can be installed onto the base such that a seal is formed between the lid and the base, the lid being surrounded by a lid flange;
a pull tab in the lid flange, the pull tab proximal to a living hinge side of an upper edge of the base, the pull tab facilitating grasping of the lid and the base to pull the lid and the base apart and breaking a frangible attachment therebetween; and
at least one attachment tab attached by the living hinge to the living hinge side of an upper edge of the base, the at least one attachment tab being attached to the same living hinge side of the upper edge of the base, the at least one attachment tab being incorporated into and substantially co-planar with the lid flange, and being bounded by frangible tab boundaries that permit the at least one attachment tab to be broken free of the lid, thereby freeing the lid from the base;
the at least one attachment tab being coordinate with a corresponding pucker element, such that when the at least one attachment tab is broken free from the lid and the lid is subsequently re-installed on the base, the at least one attachment tab is caused by the pucker elements to extend upward away from the lid flange.
