Abstract
Abstract A pallet and container combination of the type wherein the container is formed from a one-piece corrugated paperboard blank and is attached to the pallet. The container is collapsible and lies flat against the pallet in the knocked down configuration. The container is of the flanged tube type with at least one end of the container, being its bottom end, provided with foldable end flaps, each end flap extending from a respective side wall of the container and joined thereto by a fold defining score line. One of the bottom end flaps, termed a fixing flap, is provided with two score lines defining two fold axes and is stapled to the upper surface of the pallet. After erecting the knocked down container, the remaining three bottom flaps are then likewise stapled to the pallet. The container bottom is partially open. The container is storable in either one of two collapsed configurations, corresponding to the two score lines of the fixing flap. By this construction, a minimum of paperboard is employed, the pallet performing the function of a bottom panel in the erected combination. If desired, the upper end of the tube may also be provided with flaps, providing greater bulge resistance and/or for closing the container.
