Abstract
Abstract A container transport system for carrying a plurality of vehicles includes a cargo container and at least one ramp within the container. The ramp is disposable and is made of corrugated cardboard. In forming the ramp a plurality of load cells of increasing average height are positioned next to each other and are covered by a cardboard envelope. The cells are formed by folding cardboard panels into a trapezoidal shape.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
In a container transport system, for carrying a plurality of vehicles, including a cargo container and at least one ramp located within the container for compactly positioning the vehicles within the container, the improvement characterized by the formation of said at least one ramp from corrugated cardboard, said ramp comprising: a plurality of load cells of increasing average height which are positioned next to each other, each cell being formed from cardboard panels arranged in a trapezoidal shape having a base, two parallel sides of different height, a top that is inclined between the parallel sides to such an extent as to meet the neighboring edges of the tops of the adjacent cells, and a diagonal piece, at least one of the two parallel sides being reinforced by a second cardboard wall; and an envelope formed of cardboard and extending around the plurality of cells.

Claim 9
Dependent Claim
133 words
A load-bearing ramp formed of corrugated cardboard and comprising: a plurality of load cells of increasing average height positioned next to each other, each cell being formed of cardboard in a trapezoidal shape with a base section, two parallel side sections of different height, a top section that is inclined between the upper ends of the parallel side sections and a diagonal section, one of said side wall sections having a reinforcing wall section adjacent it, the lengths of the parallel sides of each cell being substantially the same as the adjacent sides of the neighboring cells, a suitable number of said load cells with inclined top sections being provided to create a ramp from one particular height to another, and an envelope formed of cardboard and extending around the plurality of cells.
Claim 10
Dependent Claim
133 words
