Abstract:

An article of manufacture, such as an encapsulated dual lens sealed instrument cover, includes four components, namely, a first lens having a peripheral edge encapsulated by a polymeric/polymeric injection molded encapsulation or border and a second lens also have a peripheral edge encapsulated by a second injection molded polymeric/copolymeric encapsulation or border. A hermetic chamber is thereby formed between the two lenses. The first encapsulation is also provided with threads or similar fastening means to readily secure the instrument cover to an instrument "can" containing any variety of instruments, such as a nautical compass, amperage/voltage, fuel, etc. The first lens is inserted into a cavity of a mold and the first encapsulation is injection molded thereabout. The latter two components are then assembled with respect to the second lens and the second encapsulation is injection molded thereabout. This double injection molding process to manufacture the dual lens sealed instrument cover creates "anti-fog" characteristics and allows more rapid and cost-effective manufacturing than heretofore provided by conventional techniques utilizing metal crimping and sealing techniques.
