Containment bag for use in a commercial disposal container

Abstract

A non-self supporting containment bag used in conjunction with a dumpster container. The bag has a center opening that extends across the top of the bag, substantially centered on the top of the bag. The top of the bags is formed with sufficient spare material at the ends of the rectangular shaped bag to allow the top to be inverted over the sides of the container. The opening when closed, has sufficient material to form opposing triangular folds that extends above the top of the bag and the top of the container, when the bag is lining the container.

The invention claimed is: 
     
       1. A containment bag for use in a dumpster container having a plurality of sidewalls defining a top and a bottom, said bottom being closed, said top being substantially open for accepting bulk materials, said plurality of sidewalls including two opposing endwalls, and said bottom defining a dumpster container interior, said containment bag comprising a bag adapted to fit within and line the interior of said dumpster container, said containment bag having a top portion substantially alignable with said top of said dumpster container, said containment bag further having a top edge alignable with the open top of said dumpster container when said containment bag is positioned in and lining a dumpster container, said containment bag having a closable opening positioned on said top portion and said closable opening substantially centered on said top portion, said containment bag top portion being adapted to form two opposing triangular shaped folds that extend above said top of said dumpster container when said closable opening is closed; and when said closable opening is opened, and said triangular shaped folds are unfolded, said closable opening on said top portion of said containment bag can be substantially aligned with the open top of a dumpster container when said containment bag is positioned in and lining the dumpster container, said top portion, when said closable opening is opened and said triangular folds are unfolded, is adapted to be inverted inside out over said top of said dumpster container; said containment bag being configured to allow said top portion triangular shaped folds to be positioned and retained in a folded position immediately adjacent the remaining portion of said top portion of said containment bag when said containment bag is loaded and said closable opening is closed, wherein said closable opening has two terminal ends, said containment bag further having a linear connector attachable to said bag top near said two terminal ends of said closable opening, said linear connector adapted to draw said terminal ends of said closable opening toward one another thereby drawing said top portion triangular shaped folds towards one another in order to position and retain said triangular shaped folds in a folded position immediately adjacent the remaining portion of said top portion of said containment bag when said containment bag is loaded and said closable opening is closed. 
     
     
       2. The containment hag according to  claim 1  wherein said containment bag further has a lining positioned on said interior surface of said containment bag. 
     
     
       3. The containment bag according to  claim 2  wherein said liner further has a top portion having a second separate closeable opening substantially centered on said liner top portion. 
     
     
       4. The containment bag according to  claim 2  wherein said liner and said bag are joined to each other near said opening. 
     
     
       5. The containment bag according to  claim 1  further having a series of handles positioned near said top portion. 
     
     
       6. The containment bag according to  claim 1  adapted to fit into the interior of a dumpster container selected from the set of roll off containers, gondola rail car containers and end dump containers and the dumpster container includes a sidewall of at least four feet in height. 
     
     
       7. The containment bag according to  claim 1  wherein said containment bag is constructed of a woven material. 
     
     
       8. A containment bag according to  claim 7  wherein woven material is woven polypropylene. 
     
     
       9. A containment bag for use in a dumpster container having a plurality of sidewalls defining a top and a bottom, said bottom being closed, said top being substantially open for accepting bulk materials, said plurality of sidewalls including two opposing endwalls, and said bottom defining a dumpster container interior, said containment bag comprising a bag configured to fit within and line the interior of said dumpster container, said containment bag having a top portion substantially alignable with said top of said dumpster container, said containment bag further having a top edge alignable with the open top of said dumpster container when said containment bag is positioned in a dumpster container, said containment bag having a closable opening positioned on said top portion and said closable opening substantially centered on said top portion, said containment bag top portion being configured to form two opposing triangular shaped folds that extend above said top of said dumpster container when said closable opening is closed; and when said closable opening is opened, and said triangular shaped folds are unfolded, said closable opening on said top portion of said containment bag can be substantially aligned with the open top of a dumpster container when said containment bag is positioned in the dumpster container, said top portion, when said closable opening is opened and said triangular folds are unfolded, is configured to be inverted inside out over said top of said dumpster container; said containment bag being configured to allow said top portion triangular shaped folds to be positioned and retained in a folded position immediately adjacent the remaining portion of said top portion of said containment bag when said containment bag is loaded and said closable opening is closed, wherein said closable opening has two terminal ends, said containment bag further having linking straps attachable to said top of said bag configured to secure said two opposing triangular shaped folds to each other in a position adjacent to said top portion of said containment bag.
