Removable fluid barrier

1. A removable fluid barrier, comprising:

a generally planar flexible body fabricated of at least one resilient material, the flexible body comprising a first layer and a second layer contacting each other, the first and second layers being fabricated in the same manner and being fabricated of the same at least one resilient material, the first and second layers having a closed-structure encapsulating a plurality of permanent magnets, adjacent permanent magnets abutting, one of the first layer and the second layer having an outer face defining a sealing surface of the removable fluid barrier.

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

3. The removable fluid barrier of claim 1 , wherein the plurality of permanent magnets is accommodated by recesses in a face of the first layer.

4. The removable fluid barrier of claim 3 , wherein the permanent magnets are generally uniformly distributed across a central portion of the first layer.

5. The removable fluid barrier of claim 3 , wherein the permanent magnets are distributed across from about 50% to about 95% of the area of the face of the first layer.

6. The removable fluid barrier of claim 3 , wherein the first layer comprises a margin extending around the periphery of the permanent magnets.

7. The removable fluid barrier of claim 3 , wherein the recesses are interconnected.

8. The removable fluid barrier of claim 1 , wherein the outer face is an outwardly-facing surface of the first layer or the second layer.

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

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