Abstract

A disposable filter bag accommodating tray insertable through an opening in a vacuum cleaner includes a front wall closing the cleaner opening and features absence of a tray rear wall permitting rearrangement of bag shape during tray withdrawl to minimize bag rupture and easy bag disposal by simply inverting the tray.

Claims

1. In a vacuum cleaner having a housing enclosing a dirt collecting compartment, and a motor blower unit associated with said housing for producing a vacuum therein, said housing being formed with an access opening communicating with said compartment the improvement comprising,

a tray insertable into said compartment through said access opening, including:

a front wall complemental in size and shape to that of said access opening, said front wall including means defining an inlet opening into said compartment for accommodating a dirt collecting nozzle,

sidewalls and a bottom wall each joined at one extremity to said tray front wall and each extending from said front wall to a free extremity, and

retaining means on said tray for sustaining a disposable dirt collecting bag on said bottom wall and between said sidewalls in operative registration with said inlet opening whereby modification of the shape of a filled dirt collecting bag sustained on said tray by said retaining means is unimpeded during withdrawal of said tray through said compartment access opening.

2. In the vacuum cleaner as set forth in claim 1 the improvement in which said sidewalls and bottom wall of said tray are latticed to maximize air flow from a dirt collecting bag sustained on said tray.

3. In the vacuum cleaner as set forth in claim 1 the improvement in which said dirt collecting bag retaining means is arranged inside said front wall.

4. In the vacuum cleaner as set forth in claim 3 the improvement in which a latch means is provided on said tray for retaining said front wall in place closing said compartment access opening, and in which a handle and a latch release means are provided on said front wall exterior beneath said inlet opening.
