Localized Dust Containment Apparatus

Abstract

A portable, removable dust containment system is disclosed for capturing and containing the dust generated by work performed on a work surface, such as the wall or ceiling inside a room. The device includes a transparent plastic bag with a first large opening at one end, and with the bag tapering to a smaller second opening at a second end. The device is removably affixed by an adhesive onto a wall surface, with the perimeter of the first opening surrounding an area where work is to be done on the wall. The user extends his or her hand through the second opening and closes the second opening. Any dust generated by the work is captured and contained within the bag and can be discarded when the bag is removed from the wall.

1 . A dust containment apparatus that is adapted to be affixed onto a wall, ceiling or other surface where dust-generating work is to be performed by a person, the apparatus comprising:
 (a) a flexible bag having an interior volume within the bag;   (b) a first opening in the bag with a perimeter that is sufficiently large to surround the area of the surface where the work is to be performed;   (c) a second opening that is sufficiently large to permit the person to extend his or her hand through the second opening and into the bag's interior volume;   (d) means for removably affixing the bag onto the wall surface with the perimeter of the first opening surrounding the work area; and   (e) means for constricting the second opening about the person's arm as they extend their hand through the second opening into the interior of the bag;   (f) wherein at least a portion of the bag is sufficiently transparent to permit the person to view the work area through the bag while the dust-generating work is being performed.   
     
     
         2 . The dust containment apparatus of  claim 1 , wherein the bag comprises a polymeric material. 
     
     
         3 . The dust containment apparatus of  claim 1 , wherein the means for affixing the bag onto the wall surface comprises an adhesive that is applied around the perimeter of the first opening. 
     
     
         4 . The dust containment apparatus of  claim 3 , further comprising a removable backing that covers the adhesive and that can be peeled away to expose the adhesive before the bag is affixed onto the work surface. 
     
     
         5 . The dust containment apparatus of  claim 2 , wherein the adhesive is applied directly onto the bag. 
     
     
         6 . The dust containment apparatus of  claim 2 , wherein the adhesive is applied onto a thin, flat ring that is attached to the bag and that extends around the perimeter of the first opening. 
     
     
         7 . The dust containment apparatus of  claim 1 , wherein the means for affixing the bag onto the wall surface comprises a thin, flat ring that is attached to the bag and that extends around the perimeter of the first opening and at least one fastener that extends through the ring and into the surface on which work is to be performed. 
     
     
         8 . The dust containment apparatus of  claim 1 , wherein the means for affixing the first end of the bag onto the wall surface comprises a plurality of fasteners that extends through the bag, near the perimeter of the first opening, and into the surface on which work is to be performed. 
     
     
         9 . The dust containment apparatus of  claim 1 , wherein the means for tightening the second opening around the worker's hand comprises an elastic band that surrounds the perimeter of the second opening. 
     
     
         10 . The dust containment apparatus of  claim 1 , wherein the means for tightening the second opening around the worker's hand comprises a drawstring that surrounds the perimeter of the second opening. 
     
     
         11 . The dust containment apparatus of  claim 1 , wherein the means for tightening the second opening around the worker's hand comprises an adjustable strap.
