Abstract
Abstract A receptacle for collecting gasoline fuel spills is provided having an outer flexible wall and a bottom pervious wall. The outer flexible wall is provided with a tie string in the neck thereof whereby the receptacle may be sealed by pulling the tie string together. A central aperture is provided in the bottom pervious wall. Secured within the central aperture is a central flexible wall having an upper and extending above an upper end of the receptacle. The upper end of the tubular central wall has a tie string therein for securing the neck of the tubular inner wall against a fill pipe of a gasoline underground tank. The receptacle contains layers of absorbent material for absorbing gasoline which may spill out of the fill pipe during filling of the underground tank. When the absorbent materials absorb sufficient gasoline, the receptacle may be removed from about the fill pipe and the drawing strings pulled together to contain the absorbed gasoline within the receptacle.
