ABSTRACT:
A fire-resistant safe is made with internal and external shells that are filled with insulation material. Hollow reinforcements interconnecting the two shells are formed as cone-shaped recesses in the internal shell having truncated bottom portions attached to the external shell. The insulation is made of a water-bearing material and the recesses are made of a resin material that melts at a temperature in excess of the boiling point of water. Funnels are formed in the external shell for adding the insulation material in a liquid state. An escutcheon for covering the funnels is anchored to the insulation material by stakes that are embedded in the insulation material before the material hardens into place.
