A spacer (30) for vessels of hazardous materials is formed of a single sheet of cardboard and includes a top panel 32 and a bottom panel 36. The top panel 32 and the bottom panel 36 are spaced from the top and the bottom of the shipping carton, respectively, by upwardly and downwardly projecting members (70, 72, 74, 88, 90, 92, 106, 108, 110, 134). When assembled, ears 120 and 124 fold over the top panel 32 and engage diagonal slots 50 and 52, thereby providing rigidity to the structure.
