Tamper evident container

A method of providing a tamper evident container comprising:

• forming a cover with a first interlocking flange with a first tab for opening the container and a first extension joined to the first tab along a frangible score line;
• forming a base with a second interlocking flange with a second tab for opening the container and a second extension joined to the second tab along a frangible score line;
• and
• forming a rim extending substantially around a perimeter of the base, the rim formed with a flat portion connected to an outer wall portion, and a flange portion extending from the outer wall portion, wherein a position of the flat portion and the flange portion correspond to a sheet line;
• and
• wherein the first and second interlocking flanges, when securely fastened together, prevent access to the first and second tabs, and require more force to separate than to sever the first and second extensions along the frangible score lines.
