Abstract
A gas or fuel cap has a relatively large diameter upper section and a relatively small diameter lower section. Threads are formed on the lower section which engage with a filler tube or conduit of a fuel storage tank mounted on a watercraft. One or both of the upper and lower sections is formed of an enhanced polyurethane material. The enhanced polyurethane material is formed by injecting a micro balloon filler into a mold containing a polyurethane. The result is a gas cap formed from a material, the enhanced polyurethane, which is buoyant.
Claims17
A cap, such as for use on a gasoline-powered watercraft having a fuel storage tank and a filler tube in communication therewith, said cap comprising an upper portion configured for manipulating said cap, and a lower portion projecting downwardly from said upper portion for securement to the filler tube of the watercraft, at least one of said upper and lower portions comprising a buoyant material to cause said cap to float in water.
A fuel cap adapted for use in a water environment, said fuel cap comprising a housing including a portion configured to engage with a filler member associated with a fuel storage tank, said fuel cap comprising a buoyant material to allow floatation of said fuel cap.
A gas cap for closing off a gasoline storage tank which supplies fuel to an internal combustion engine of a watercraft such as those used on a large body of water, the watercraft including a filler tube in communication with the storage tank, said gas cap including an upper body member adapted to permit removal and installation of said gas cap on the filler tube of the watercraft, and a lower body member depending downwardly from a lower side of said upper body member, said lower body member being configured for threadingly engaging with an upper end of the filler tube to secure said gas cap thereon, one of said body members being constructed of buoyant material to cause floatation of said gas cap when same comes into contact with water.
