Abstract: A cargo carrier is disclosed which includes walls including a plurality of adjacent plates with outer surfaces, at least a selected pair of the adjacent plates being spaced from each other by a predetermined amount. A joint is provided for joining the selected pair of adjacent plates, which includes an inner strip extending between the adjacent plates, the inner strip overlying at least a marginal portion of each plate. An outer strip extends between the adjacent plates and defines a generally vertical axis located generally centrally of the space, the outer strip overlying the inner strip and having an outer surface and an inner surface which faces the inner strip. The inner surface includes a pair of adjacent surface portions which respectively taper from the outer strip toward the inner strip in respectively opposite directions such that the maximum dimension between the inner and outer strip is substantially coincident with the vertical axis.
