  • Patent number: 7979957
    Abstract: A vacuum cleaner attachment useful to collect dispersed packing particulates and the like comprises a thin-walled polymeric enclosure defined by a plurality of generally planar panels surrounding at their free edges a receiving opening through which the particulates are collected by the vacuum draw against a perforated screening structure. As the particulates accumulate in the enclosure the large pressure drop across the outer ranks thereof produces inward pressure forces across the panels, resulting in the inward flexures thereof to assist in the retention of the particulates in the enclosure as it is moved over a collection receptacle.
    Type: Grant
