Abrégé
(EN)
Fire and heat protective containers having two matable portions (12, 14), the outer walls of which are formed as hollow shells (42, 44) filled with a ceramic gel material (46) containing at least water glass and a polyvalent metal salt, preferably calcium chloride. For ensuring that stored articles are not exposed to temperatures greater than 125 degrees F, a layer of low-density, expended or foamed plastic insulation (60) and a layer of phase change material (62) are provided inwardly of the gel layer. A preferred phase change material is a mixture of water glass and a hydrated salt, preferably sodium phosphate, having a melting point around 120 degrees F and a heat of fusion of at least 250 joules per gram. The phase change material is also contained in hollow shells (64, 66), the walls of both the outer and inner shells being molded plastic parts.
