ABSTRACT:
An improved two piece food package. The package includes lid and dish members. The lid has formed in its perimeter three slots, two on one side and a single slot on the opposite side. The dish member has three locking tabs designed to engage the slots in the lid to thereby hold the two members together as a unit package. Under the single tab is formed a locking lug. The locking lug extends outward far enough to interfere with a portion of the lid when the lid and dish are assembled. This interference causes the dish sidewall to bow, creating a lock of the dish sidewall into corners of the lid.
