Heat-intercepting garment or blanket

Image Number 4 for United States Patent #5072455.

A heat-intercepting shield or shroud in the form of a garment, blanket or belt having on at least one surface thereof one or more pockets to receive replaceable packets of refreezable material which absorb large quantities of heat as the material melts. Each pocket has two coextensive fabric layers stitched together to form opposite pocket walls. Over the entire pocket area and next to the one wall are coextensive layers of non-breathable continuous reflective material and of insulating material. These materials are flexible and are stitched next to that one pocket wall in seams at the edge of the pocket so that both heat reflection and retardation of heat flow by the insulation occurs over the entire pocket area. Between the layer of insulation and the other pocket wall is a space for a heat absorbing packet or packets of frozen gel. The side of the shield or shroud with the packet or packets is placed toward the object to be cooled or protected from external radiant, conductive or convective heat.
