  • Patent number: 4653711
    Abstract: A flat sheet of resilient material, such as rubber or plastic, is molded or cut to form a flat loop or ring encircling a central opening. A tensioning tab on one side of the loop projects into the opening toward the opposite side of the loop, and a retaining tab is mounted on a support which projects into the opening from the opposite side of the loop. The hanger has front and back surfaces, and the retaining tab projects outwardly away from the front surface of the loop. Adhesive on the back surface of the loop is used to support the hanger in a generally planar, vertical disposition on the vertical inside wall of a fuel tank access door in an automotive vehicle. When the access door is opened, the top of the loop may be resiliently folded downwardly away from the surface of the access door, and the neck of a fuel tank cap may be inserted into the central opening in the hanger.
