Protective cover for preventing spilled liquids from flowing into drains or holes

Abstract

A protective cover for drains and other holes is provided which prevents spills and unwanted liquids from flowing therein. The protective cover 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 around a peripheral edge of the sheet. The pliable, liquid impermeable material includes an exposed surface that is tacky so that it ahderes to a surface surrounding the drain or other hole to prevent the flow of liquid therebetween.

1 . A protective cover for preventing spills and/or unwanted liquids from flowing into drains or holes, the protective cover comprising: 
 a sheet of flexible, liquid impermeable material having top and bottom surfaces, the sheet having a first weight per unit area; and    a pliable, liquid impermeable material attached to the bottom surface of the sheet about a peripheral edge of the sheet and having a second weight per unit area greater than the first weight per unit area, the pliable, liquid impermeable material having an exposed surface that is inherently tacky so that it may adhere to and form a seal with a surface surrounding the drain or hole to prevent flow of liquid therebetween upon contact between the tacky exposed surface and the surface surrounding the drain or hole.    
   
   
       2 . The protective cover of  claim 1 , wherein the pliable, liquid impermeable material is selected from the group consisting of polyurethane, polyvinyl chloride, vinyls, silicons and soft rubber.  
   
   
       3 . The protective cover of  claim 1 , wherein the sheet of flexible, liquid impermeable material is selected from the group consisting of vinyls, silicons, polyurethane, polyvinyl chloride, soft rubber and plastic.  
   
   
       4 . The protective cover of  claim 1 , wherein the sheet of flexible, liquid impermeable material has a shape selected from the group consisting of square, circular, triangular and rectangular.  
   
   
       5 . The protective cover of  claim 1 , wherein at least the top portion of the sheet of flexible, liquid impermeable material comprises a color that is highly visible.  
   
   
       6 . The protective cover 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.  
   
   
       7 . The protective cover of  claim 1 , further comprising at least one stabilizing member provided on the bottom surface of the sheet between the pliable, liquid impermeable material.  
   
   
       8 . A protective cover for preventing spills and/or unwanted liquids from flowing into drains or holes, the protective cover 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.    
   
   
       9 . The protective cover of  claim 8 , wherein the pliable, liquid impermeable material is selected from the group consisting of polyurethane, polyvinyl chloride, vinyls, silicons and soft rubber.  
   
   
       10 . The protective cover of  claim 8 , wherein the exposed surface of the pliable, liquid impermeable material is inherently tacky.  
   
   
       11 . The protective cover of  claim 8 , 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.  
   
   
       12 . The protective cover of  claim 8 , wherein the sheet of liquid impermeable material has a shape selected from the group consisting of square, circular, triangular and rectangular.  
   
   
       13 . The protective cover of  claim 8 , 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.  
   
   
       14 . The protective cover of  claim 8 , wherein at least the top surface of the sheet of liquid impermeable material comprises a color that is highly visible.  
   
   
       15 . The protective cover of  claim 8 , wherein the sheet of liquid impermeable material comprises a sheet of woven or nonwoven fabric surrounded by a liquid impermeable material.  
   
   
       16 . A protective cover for drains or holes to prevent spills and/or unwanted liquids from flowing into drains or holes, the protective cover 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.    
   
   
       17 . The protective cover of  claim 16 , 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.  
   
   
       18 . The protective cover of  claim 16 , wherein the thickened portion comprises a material selected from the group consisting of polyurethane, polyvinyl chloride, vinyls, silicons and soft rubber attached to the bottom surface of the sheet adjacent the peripheral edge of the sheet, the thickened portion material being pliable.  
   
   
       19 . The protective cover of  claim 18 , wherein the exposed surface of the thickened portion material is inherently tacky.  
   
   
       20 . The protective cover of  claim 16 , wherein the thickened portion of the sheet includes a first weight per unit area, and wherein other portions of the sheet include a second weight per unit area less than the first weight per unit area.  
   
   
       21 . The protective cover of  claim 16 , wherein the sheet of liquid impermeable material has a shape selected from the group consisting of square, circular, triangular and rectangular.  
   
   
       22 . The protective cover of  claim 16 , wherein the sheet of liquid impermeable material comprises a flexible sheet of woven or nonwoven fabric surrounded by a liquid impermeable material.  
   
   
       23 . The protective cover of  claim 16 , further comprising at least one stabilizing member provided on the bottom surface of the sheet between the thickened portion.
