Abstract
Abstract A gasoline dispenser is connected to a gasoline supply tank by a gasoline supply line. At the point where the supply line is to connect to the gasoline dispenser, a flex hose is used as the connecting mechanism. The flex hose connects to a shear valve capable of stopping the flow of gasoline from the gasoline supply tank to the gasoline dispenser. A container is installed under the dispenser and the flex hose is positioned within the container. Thus, the flex hose is protected from the environment and the soil is protected from gas spills associated with maintenance of the gas dispenser.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
276 words
An apparatus for protecting soil against gasoline spillage, in connection with dispensing gasoline, comprising: (a) at least one gasoline supply tank; (b) a gasoline dispenser, having a base portion, said dispenser adapted to be mounted to a foundation slab, wherein said base portion of said gasoline dispenser includes a standard shear box positioned underneath said gasoline dispenser, said shear box sized to extend below said foundation slab; (c) at least one gasoline supply line, corresponding to each gasoline supply tank, each gasoline supply line in communication with each gasoline supply tank and said gasoline dispenser, for supplying gasoline from each gasoline supply tank to said gasoline dispenser; (d) at least one flex hose, corresponding to each gasoline supply line, each flex hose in communication with the end of each gasoline supply line closest to said gasoline dispenser, for connecting each gasoline supply line to said gasoline dispenser; and (e) a non-concrete, gasoline-impermeable container for shielding each flex hose against the environment and for containing gasoline spills, having a mating opening for receiving and mating with said shear box of said base portion of said gasoline dispenser wherein said mating opening is detachably affixed to said shear box beneath said foundation slab with screw fastening means, said container positioned underneath said mating opening, and having at least one supply line opening for each gasoline supply line for receiving each supply line, each supply line opening positioned in said container at an advantageously selected location, said container shielding each flex hose from contact with said soil, and said container having a vertically oriented reinforcement mechanism on the exterior of said container for providing increased strength against exterior pressure.
