  • Patent number: 5410775
    Abstract: An attachment for the majority of conventional vacuum cleaners and reversible blower devices for collecting lightweight, loose-fill packaging materials for disposal or reuse includes two, nesting sections. The first section, when used alone, releasably attaches over the bin or the body of a portable, hand held vacuum cleaner. An inlet end defines an irregular collection edge to aid in preventing entry of dust and extraneous, heavier materials. A one-way, hinged door defining perforations allows air to enter to move previously collected packaging material away prior to opening of the door to admit additional packaging material. For full sized vacuum cleaners, the first section removably mounts through an aperture formed in an end wall of a larger receptacle having a universal coupler for attachment to the hose or hose coupler of the majority of full sized vacuum cleaners. The first section may be made larger and used alone to attach to a full sized vacuum cleaner.
