ABSTRACT:
A pizza box having a plurality of ribs, which are selectively moveable between a first stored position and a second upright position is provided. The ribs are coupled to at least one actuating strip, which enables the ribs to be simultaneously shifted from the first stored position to the second upright position. The ribs and the actuating strip are formed from the same piece of material. The actuating strip may be configured to interlock with the box to maintain the ribs in the second upright position. There is also a stop tab configured to prevent the actuating strip from moving the ribs beyond a predetermine point.
