Abstract
A box having a full size configuration and a reduced size configuration is provided. The full size box can hold, for example, an entire pizza. When the full volume is no longer required, the box can be reduced in size by eliminating certain portions thereof by tearing along preformed perforated score lines and folding along specially provided score lines. In accordance with the invention, no tools are required to form the smaller size box from the blank of the full size box. A microwave susceptor material can be provided on the base of the box to crispen leftovers that are heated in a microwave oven.
