ABSTRACT:
A tamper evident container assembly for perishable foods such as dairy products. A container is provided with a removable lid which mechanically interlocks with the container in a conventional fashion. A fragible ring is wedged onto the lid to prevent release of the mechanical interlock and removal of the lid. A frangible tab section of the ring must be broken away to release the ring and permit removal of the lid. Absence or breakage of the ring provides visual evidence of possible product tampering.
