Drain blocker

Abstract

A device for providing a temporary cover for drains and other holes is provided, according to the present invention, to prevent liquids from flowing therein. The inventive temporary covering device generally includes a sheet of flexible, liquid impermeable material having top and bottom surfaces. A pliable, liquid impermeable material is attached to the bottom surface of the sheet about a peripheral edge of the sheet. The pliable, liquid impermeable material includes an exposed surface that is tacky so that it may adhere to a surface surrounding the drain or other hole to prevent the flow of liquid therebetween.

         5 . The device of  claim 1 , wherein the device is postionable over the drain or hole such that the exposed surface of the pliable, liquid impermeable material contacts a portion of the surface surrounding the drain or hole whereby the device is adapted for preventing a liquid from passing through the drain or hole.  
     
     
         6 . The device of  claim 1 , wherein at least the top surface of the sheet of flexible, liquid impermeable material comprises a color that is highly visible.  
     
     
         7 . The device of  claim 1 , wherein the sheet of flexible, liquid impermeable material comprises a sheet of woven or nonwoven fabric surrounded by a liquid impermeable material.  
     
     
         8 . The device of  claim 1 , further comprising at least one stabilizing member provided on the bottom surface of the sheet between the pliable, liquid impermeable material.  
     
     
         9 . A device for providing a temporary cover for drains or holes to prevent liquids from flowing therein, said device comprising: 
 a sheet of liquid impermeable material having top and bottom surfaces; and    a pliable, liquid impermeable material attached to the bottom surface of the sheet about a peripheral edge of the sheet, the pliable, liquid impermeable material having an exposed surface that is tacky such that it may adhere to a surface surrounding the drain or hole to prevent flow of liquid therebetween.    
     
     
         10 . The device of  claim 9 , wherein the pliable, liquid impermeable material is selected from the group consisting of polyurethane, polyvinyl chloride, vinyls, silicons and soft rubber.  
     
     
         11 . The device of  claim 9 , wherein the exposed surface of the pliable, liquid impermeable material is inherently tacky.  
     
     
         12 . The device of  claim 9 , wherein the sheet of liquid impermeable material is flexible and is selected from the group consisting of vinyls, silicons, polyurethane, polyvinyl chloride, soft rubber and plastic.  
     
     
         13 . The device of  claim 9 , wherein the sheet of liquid impermeable material has a shape selected from the group consisting of square, circular, triangular and rectangular.  
     
     
         14 . The device of  claim 9 , wherein the sheet of liquid impermeable material includes a first weight per unit area, and wherein the pliable, liquid impermeable material includes a second weight per unit area greater than the first weight per unit area.  
     
     
         15 . The device of  claim 9 , wherein the device is postionable over the drain or hole such that the exposed surface of the pliable, liquid impermeable material contacts a portion of the surface surrounding the drain or hole whereby the device is adapted for preventing a liquid from passing through the drain or hole.  
     
     
         16 . The device of  claim 9 , wherein at least the top surface of the sheet of liquid impermeable material comprises a color that is highly visible.  
     
     
         17 . The device of  claim 9 , wherein the sheet of liquid impermeable material comprises a sheet of woven or nonwoven fabric surrounded by a liquid impermeable material.  
     
     
         18 . A device for providing a temporary cover for drains or holes to prevent liquids from flowing therein, said device comprising: 
 a sheet of liquid impermeable material having top and bottom surfaces, the sheet having a thickened portion provided adjacent a peripheral edge of the sheet, the thickened portion including an exposed surface that is tacky such that it may adhere to a surface surrounding the drain or hole to prevent flow of liquid therebetween.    
     
     
         19 . The device of  claim 18 , wherein the sheet of liquid impermeable material is flexible and is selected from the group consisting of vinyls, silicons, polyurethane, polyvinyl chloride, soft rubber and plastic.
