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 durable backing layer and a pliable, tacky sealing layer adjacent a portion of the durable backing layer which conforms and adheres to a surface surrounding the drain to reduce or eliminate the flow of liquids into the drain. The pliable, tacky sealing layer can have a periphery inside the periphery of the durable backing layer.

Claims (26)

1. A protective cover for installation over a drain comprising:

a durable backing layer having a periphery; and

a pliable, tacky sealing layer adjacent a portion of the durable backing layer structured and arranged to block spills from entering the drain having a periphery inside the periphery of the durable backing layer; and

wherein the pliable, tacky sealing layer has an interior border defining a sealing layer band between the interior border and the periphery of the pliable, tacky sealing layer, and the sealing layer band has a width of from 1 inch to 1 foot.

2. A protective cover for installation over a drain comprising:

a durable rubber backing layer having a periphery and a thickened portion adjacent the periphery; and

a pliable, tacky urethane sealing layer structured and arranged to block spills from entering the drain adjacent a portion of the durable rubber backing layer, the pliable, tacky urethane sealing layer having a periphery inside the periphery of the durable rubber backing layer; and

wherein the pliable, tacky sealing layer has an interior border defining a sealing layer band between the interior border and the periphery of the pliable, tacky sealing layer.

3. The protective cover of claim 1 , wherein at least a portion of the periphery of the pliable, tacky sealing layer is at least 0.25 inch inside the periphery of the durable backing layer.

11. The protective cover of claim 1 , wherein the pliable, tacky sealing layer has a durometer hardness of less than 80 F.

12. The protective cover of claim 1 , further comprising a stabilizing mat adhered to an interior region of the durable backing layer.

13. The protective cover of claim 2 , wherein the durable rubber backing layer further comprises an interior region having a thickness of from 0.03 to 0.25 inch and the thickened portion has a thickness of from 0.06 to 0.5 inch.

14. The protective cover of claim 2 , wherein the thickened portion has a bottom surface having a surface area of from 1 to 25 square feet.

15. The protective cover of claim 2 , wherein the pliable, tacky sealing layer has a thickness of from 0.03 to 0.5 inch.

16. The protective cover of claim 2 , wherein at least a portion of the periphery of the pliable, tacky sealing layer is at least 0.25 inch inside the periphery of the durable backing layer.

17. The protective cover of claim 2 , wherein the durable backing layer has a length of at least 1 foot and a width of at least 1 foot.

18. The protective cover of claim 2 , wherein the durable backing layer comprises natural rubber, synthetic rubber, nitrile rubber, vinyl, and/or reinforced fabric impregnated with and/or coated with rubber and/or vinyl.
