Abstract
A fire-resistant case for protecting electronic storage media includes a main body and lid, each of which is assembled from a pair of subassemblies. The outer subassemblies of the lid and main body are made from an integral resin body having inner, outer, and intermediate shells for encasing a layer of water-bearing material. The outer shells form the outer skin of the case, the inner shells form a moisture-resistant layer, and the intermediate shells form an outer seal between the main body and lid. An inner subassembly of the main body is built up from an inner repository of heat-conducting material, slabs of phase-changing material, and a foam insulation that encases the inner respository and phase-changing material. The foam insulation is formed as a self-skinning foam for forming a part of an inner seal between the main body and lid. An inner subassembly of the lid is constructed in a variety of ways consistent with the purposes of the other named layers of the case.
