Abstract
A food plate package having a bottom plate and a top cover for the temporary storage of prepared food products, the top cover being convex-oval, with support ribs integrally formed in the cover. The support ribs provide a raised flat surface to stably support another food plate package when stacking one on top of the other. Channels are provided between the support ribs for an air space between adjacent packages when stacked and the subsequent dissipation of overly high temperatures in the central portion.
