  • Patent number: 4442567
    Abstract: The present specification discloses a combination dust pan and refuse container constructed of inexpensive lightweight materials which is highly transportable and repositionable from an upright refuse transporting position to a horizontal refuse collecting position. The combination dust pan and container is made up of a framework which distends and substantially encloses a conventional disposable trash bag, four circumferentially spaced ground contacting wheels and a dust pan which depends outwardly from the frame near the mouth of the bag. In the transporting position, all four wheels contact the ground and provide a stable base. In the collecting position, the outwardmost edge of the dust pan and two of the wheels which are on a common axle contact the ground. A handle is provided which projects upwardly in both the transporting and collecting positions to facilitate mobility of the pan/container combination.
