A container having a lid includes a cavity defined by a bottom wall and a first plurality of upstanding sidewalls. A first flange is formed integrally with the first plurality of upstanding sidewalls at their respective uppermost ends and extends outwardly with respect to the cavity. A second plurality of upstanding sidewalls is mounted about the outer periphery of the first flange. A second flange is formed integrally with the second plurality of upstanding sidewalls at their respective uppermost ends and extends outwardly with respect to the cavity. The second flange has a tear tab adapted to be gripped by a user. The tear tab is corner-mounted in a first embodiment and is formed on a leading end of the second flange in a second embodiment. In both embodiments, the tear tab is bordered by perforation lines and clear cut lines and is easily seen if it has been torn.

1. A tamper-evident package comprising: a container comprising: a bottom wall;a sidewall projecting upwardly from said bottom wall to an uppermost end;a cavity defined by said bottom wall and said sidewall;a first flange extending outwardly from said cavity at said uppermost end, said first flange having a first longitudinal extent, an outer edge, and an inner edge;a peripheral wall projecting upwardly from said first flange;a second flange extending outwardly from said peripheral wall and parallel to said first flange, said second flange having a gap and a second longitudinal extent;a removable tab projecting outwardly from said second flange, said tab defining: a first perforation line transversing said second longitudinal extent on a first side of said tab;a second perforation line transversing said second longitudinal extent opposite and parallel to said first perforation line on a second side of said tab;a first clean cut line extending from an innermost end of said first perforation line, and extending between said second flange and said first flange;a second clean cut line extending from an innermost end of said second perforation line, extending parallel to said first clean cut line between said second flange and said first flange;a third straight perforation line formed in said first flange, extending from a first lowermost end of said first clean cut line, transversing said first longitudinal extent, and terminating at a first point between said outer edge and said inner edge;a fourth straight perforation line formed in said first flange parallel to said third straight perforation line, extending from a second lowermost end of said second straight clean cut line, transversing said first longitudinal extent, and terminating at a second point between said outer edge and said inner edge; and,a fifth perforation line formed in said first flange and extending between said first point and said second point;a reclosable lid comprising: a closed cover; and,a flexible hinge resiliently seated within said gap and enabling said lid to pivot between: a closed position;an open position; and,a reclosed position;wherein properly removing said lid with lifting or depressing, said tab: breaks said second flange along said first perforation line and said second straight perforation line;separates said first wall and said second wall along said first straight clean cut line and said second straight clean cut line;breaks said first flange along said third perforation line, said fourth straight perforation line, and said fifth straight perforation line;detaches said tab from said container while maintaining said hinge of said lid resiliently seated within said gap of said container; and, therebyallows said lid to pivot between said closed position, said open position, and said reclosed position; and,wherein improperly removing said lid without lifting or depressing said tab: unseats said hinge from said gap;disconnects said lid from said container; and, therebyprevents said lid from pivoting between said closed position, said open position, and said reclosed position. 2. The tamper-evident package of claim 1, wherein: said gap of said container is slightly smaller than said hinge of said lid. 3. The tamper-evident package of claim 1, wherein: said hinge of said lid is slightly larger than said gap of said container. 4. The tamper-evident package of claim 1, wherein: said hinge of said lid is a plate formed from a flexible and resilient material capable of lying flat in repose and bowing in response to an external force. 5. A tamper-evident assembly comprising: a container comprising: a bottom wall;a sidewall projecting upwardly from said bottom wall to an uppermost end;a cavity defined by said bottom wall and said sidewall;a first flange extending outwardly from said cavity at said uppermost end, said first flange having a first longitudinal extent, an outer edge, and an inner edge;a peripheral wall projecting upwardly from said first flange;a second flange extending outwardly from said peripheral wall and parallel to said first flange, said second flange having a gap and a second longitudinal extent;a folding tab projecting outwardly from said second flange, said tab defining: a first perforation line transversing said second longitudinal extent on a first side of said tab;a second perforation line transversing said second longitudinal extent opposite and parallel to said first perforation line on a second side of said tab;a first clean cut line extending from an innermost end of said first perforation line, and extending between said second flange and said first flange;a second clean cut line extending from an innermost end of said second perforation line, extending parallel to said first clean cut line between said second flange and said first flange;a third straight perforation line formed in said first flange, extending from a first lowermost end of said first clean cut line, transversing said first longitudinal extent, and terminating at a first point between said outer edge and said inner edge;a fourth straight perforation line formed in said first flange parallel to said third straight perforation line, extending from a second lowermost end of said second straight clean cut line, transversing said first longitudinal extent, and terminating at a second point between said outer edge and said inner edge; and,a non-perforated folding line formed in said first flange and extending between said first point and said second point;a hinged lid comprising: a closed cover; and,a flexible hinge resiliently seated within said gap and enabling said lid to pivot between: a closed position;an open position; and,a reclosed position;wherein properly removing said lid with lifting or depressing said tab: breaks said second flange along said first perforation line and said second straight perforation line;separates said first wall and said second wall along said first straight clean cut line and said second straight clean cut line;breaks said first flange along said third perforation line and said fourth straight perforation line;folds said first flange along said non-perforated straight folding line;pivots said tab away from said container while maintaining said hinge of said lid resiliently seated within said gap of said container; and, therebyallows said lid to pivot between said closed position, said open position, and said reclosed position; and,wherein improperly removing said lid without lifting or depressing said tab: unseats said hinge from said gap;disconnects said lid from said container; and, therebyprevents said lid from pivoting between said closed position, said open position, and said reclosed position. 6. The tamper-evident assembly of claim 5, wherein: said gap of said container is slightly smaller than said hinge of said lid. 7. The tamper-evident assembly of claim 5, wherein: said hinge of said lid is slightly larger than said gap of said container. 8. The tamper-evident assembly of claim 5, wherein: said hinge of said lid is a plate formed from a flexible and resilient material capable of lying flat in repose and bowing in response to an external force.
