  • Patent number: 4988024
    Abstract: This invention provides a novel collection wire basket that has a bottom mesh structure. This permits sand and other debris to fall from the basket retaining an item that is larger than the openings in the wire basket. The basket also contains a bottom deflector plate which deflects sand or other materials away from the user's body. The side of the basket abutting the user's body is a solid panel to prevent contact of the contents of the container with the user's body.
