ABSTRACT:
A multiple container assembly having particular use in handling and transporting pizzas. The assembly includes an upper container formed of folded corrugated paperboard and having a bottom wall, a side wall and a top. The upper container is stacked on a second lower container which is composed of a bottom, a side wall and an open top. A panel is connected to opposed portions of the side wall of the lower container along a fold line and each panel has a pair of spaced slits extending from the free edge of the panel to the fold line which divides each panel into a central section and a pair of end sections. The central section of each panel is folded inwardly about the fold line and disposed generally horizontal to provide a seat for the upper container, while the end sections of each panel are disposed flatwise to the side wall of the upper container. A tab is connected to the end of each end section by a second fold line and each tab is received within a vertical slit in the upper container to lock the upper container to the lower container.
