  • Patent number: 5878461
    Abstract: A device for collecting, compressing and discharging loose material, the device being formed from a body of flexible material having a self-sustaining, scoop-shape. The body has a flat bottom, lateral sides, and an open top. The bottom merges with the lateral sides at one of the ends of the body to form a flat edge thereat, and at its other end, the body has an end wall extending upright from the bottom. The lateral sides have upper edges extending from the flat edge upwardly to an upper edge of the end wall thereby defining an open, interior cavity adapted for receiving loose material therein. The lateral sides and the bottom are joined to the end wall by fold lines forming stabilizing corners which provide the self-sustaining shape of the body while the flexible material of the body allows the lateral sides to be overlapped on one another to compress and confine the loose material in the cavity.
