  • Patent number: 6871762
    Abstract: A container for storage, dispensing, and spreading of ice-thawing materials for use around doorways, walkways, and other entrances where people walk and ice can form. It includes a storage hopper safe from the weather elements, a rotary dispenser drum which dispenses a pre-measured amount of ice-melt material or other granulate such as sand to a spreader try which can be removed and used to spread material where needed. The storage hopper has a discharge hole in the base that matches the hole in the rotary drum dispenser. The drum dispenser is a hollow drum suspended in air where the hole meets the hole in the hopper. The drum is secured in place by the ends which protrude through either the outside of the hopper wall or the unit container wall, the drum can be rotated manually or mechanically to place the hole either on top for filling of tube or on the bottom for discharging the materials from the tube.
