  • Patent number: 5741062
    Abstract: A flashlight outer sleeve is formed of rubber which has an integral camouflage pattern. Because the multicolored elements of the sleeve are fused together, a scratch or abrasion will not appreciably alter its appearance. The rubber sleeve is formed in a compression molding process. Multilayer rubber sheet assemblies are prepared for the compression molding process by first die-cutting camouflage pattern shapes from thin sheets of rubber of two or more colors. The die cut shapes are placed on rectangular base sheets and pressed into temporary engagement to create multilayer sheet assemblies. The sheet assemblies are disposed in conventional rubber compressing molding molds and are heated. As the base sheet and the pattern shapes are comprised of identical rubber material, except for color, the heated rubber flows such that the multilayer assemblies take on the shape of the molded parts.
