Abstract: A pizza box is formed of an upper panel and a lower panel which, by a series of fold lines is formed into a closable box. The upper panel includes a central, transversely extending score line. The lower panel also includes a centrally located, transversely extending score line. The score lines penetrate through the material forming the box. These score lines, as opposed to the fold lines which are formed in the blank to form a box, facilitate the collapse of the box, so that quarter portions of the collapsed box are stacked in an overlying condition. The reduced area of the collapsed box, formed into quarters, facilitates the storage of the box for recycling purposes.
