  • Patent number: 5209392
    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.

  • Patent number: 4801077
    Abstract: The carton is comprised of a corrugated paperboard tray and a corrugated paperboard cover. The tray has upstanding side wall panels and upstanding end wall panels, the upstanding end wall panels having hand holes for lifting the tray. The cover has a top panel provided with a non-slip surface, trapezoidally configured side wall pane=ls and trapezoidally configured end wall panels. Each of the side wall panels and the end wall panels of the cover are hingedly connected to the top panel by reason of weakened fold lines. The corrugations of the cover extend at right angles to the fold lines for the cover's end wall panels so as to provide a greater degree of deflective resistance to the cover's end wall panels then that imparted to the cover's side wall panels with the consequence that the end wall panels of the cover exert a greater amount of pressure against the end wall panels of the tray than that exerted by the cover's side wall panels.
