  • Publication number: 20030041490
    Abstract: According to an embodiment, the apparatus includes a conduit, a base assembly, and a drum. The base assembly has a blower unit to create suction at openings of a tube that is coupled to the conduit. The blower unit has sufficient strength so that particles can be sucked into the tube and then blown through the conduit past a distal opening of the conduit, while the conduit is vertically oriented such as a Christmas tree on display. The base assembly has a first catch that extends away from and surrounds the tube openings. The drum has a number of connected sections where each can pivot with respect to adjacent ones so that the sections can be folded on top of each other to form a stack. Each upper portion of the section has a fastening mechanism which allows upper portions to be removably attached to the portions of adjacent sections so as to form another catch that has an opening.
