Abstract

A removable fluid barrier comprises a generally planar flexible body fabricated of at least one resilient material and encapsulating a plurality of permanent magnets. The flexible body has an outer face defining a sealing surface of the removable fluid barrier.

Claims (17)

1. A removable fluid barrier, comprising:

a generally planar flexible body fabricated of at least one resilient material, the flexible body having a single, continuous structure enclosing a plurality of permanent magnets and a reinforcement sheet, the flexible body having opposing faces comprising a first face and a second face, at least one of the opposing faces defining a sealing surface of the removable fluid barrier,

wherein the plurality of permanent magnets are positioned closer to the first face of than to the second face, the reinforcement sheet being disposed between the permanent magnets and the first face of the flexible body.

2. The removable fluid barrier of claim 1 , wherein the flexible body is formed by a single casting.

3. The removable fluid barrier of claim 1 , wherein the reinforcement sheet is selected from the group consisting of fiberglass cloth, and a resilient fabric or a resilient mesh fabricated of one or more other materials.

4. The removable fluid barrier of claim 1 , wherein the first face of the flexible body comprises a textured surface.

5. The removable fluid barrier of claim 4 , wherein the textured surface has a non-planar topography.

6. The removable fluid barrier of claim 1 , wherein the plurality of permanent magnets comprises one or more rare earth magnets.

7. The removable fluid barrier of claim 1 , wherein each of the permanent magnets comprises an epoxy coating.

8. The removable fluid barrier of claim 1 , wherein each of the permanent magnets comprises a magnet body and ferromagnetic plate.

9. The removable fluid barrier of claim 8 , wherein the ferromagnetic plate is a steel disc.

10. The removable fluid barrier of claim 8 , wherein the magnet body is a rare earth magnet.

11. The removable fluid barrier of claim 1 , wherein the permanent magnets comprise two or more magnet bodies magnetically fastened to a ferromagnetic plate.

12. The removable fluid barrier of claim 11 , wherein the ferromagnetic plate is a steel plate or a steel sheet.

13. The removable fluid barrier of claim 11 , wherein each of the magnet bodies is a rare earth magnet.

14. The removable fluid barrier of claim 1 , wherein the at least one resilient material comprises a polymer.

15. The removable fluid barrier of claim 1 , wherein the flexible body is fabricated of polyurethane.
