ABSTRACT:
A vacuum cleaner filter bag for an upright vacuum cleaner comprising an air pervious filter receptacle and an air impervious feed tube interconnected together so that the interior of the filter receptacle is in air-flowing relationship with the interior of the feed tube, where the feed tube is adapted to be connected to the vacuum cleaner. A collar is intermediately disposed within the filter receptacle and secured therein by a clamping ring disposed externally of the filter receptacle in juxtaposition with an upper portion of the collar. An air impervious dust receptacle is removably disposed within a lower portion of the filter receptacle with a mouth portion of the dust receptacle being disposed about a lower end of the collar. A resiliently expandable ring releasably secures the dust receptacle mouth portion about the collar so that the dust receptacle is maintained in an open mouth suspended condition within the filter receptacle to receive and collect debris introduced into the filter receptacle. A sealable opening is provided in the filter receptacle to permit insertion and removal of the dust receptacle from the filter receptacle.
