Claim:
A paper ramp for use in the unloading of a wheeled or castered product from a base having a horizontal surface, the paper ramp comprising: a bottom member made from a paper blank folded into a wedge shaped structure defining an interior space and comprising an elongated sloping top panel having opposing side edges and an underside, two vertically oriented, opposing, triangular side panels foldably attached to the top panel along the opposing side edges, each side panel defining a bottom edge and a rear edge and a plane, two horizontally oriented bottom panels, each bottom panel hingedly attached to one the side panels along the bottom edge of the side panel and folded inward along their respective bottom edges so that the bottom panels are in flat abutting relationship with each other, a first closure flap hingedly attached to one of the side panels along the rear edge, and a second closure flap hingedly attached to the other side panel along its rear edge, the first and second closure flaps defining planes, the first and second closure flaps being folded inside the wedge shaped structure interior space so that the plane defined by the first closure flap forms an acute included angle with the plane defined by the side panel to which the first closure flap is attached and the plane defined by the second closure flap forms an acute included angle with the plane defined by the side panel to which the second closure flap is attached, the first and second closure flaps each having a slanted top edge that is co-planar with and abuts the underside of the top panel and a horizontal bottom edge that is co-planar with abuts the horizontally oriented bottom panel so that the first and second closure flaps abut and support the sloped top panel along their entire top edges; and a separate pre-formed paper top member comprising an elongated flat upper panel having a length, opposing side edges and two integrally formed, raised rails located in spaced parallel relationship to each other and extending the length of the upper panel, the top member further comprising side flaps extending downward from the side edges and a rear extension panel extending rearward from the upper panel and hingedly attached thereto along a fold line and configured to extend over and rest on the horizontal surface of the base; wherein the top member is affixed to the bottom member such that the upper panel is substantially coextensive with the sloping top panel.
