Abstract
A generally rectangular, double-walled box 10 is blow molded in a pair of separately formed diagonal halves 10a and 10b, each including adjoining side walls 11 and 12 subtending a diagonal half of the bottom 15 of box 10. Walls 11 and 12 of each diagonal half are oriented obliquely to the parting plane 43 of a mold 40 that has a cavity 42 and core 41 for forming the inner and outer walls of each box half 10a and 10b. The halves are assembled together along a junction region 13 and 14, preferably so as to trap a hinged cover 20. By filling the interwall cavities of the box with a suitable insulation material, the box can be used for fire resistant storage or cold storage.
