Abstract

The present invention provides a method for the containment of fluids that flow from a bowl of a commode installed in an aircraft lavatory through a space between a rim of the bowl and a shroud positioned above the rim. The method includes securing a central portion of an apron against an exterior perimeter of the bowl and fastening a plurality of fastening points formed in an outer peripheral portion of the apron to fixed anchors to thereby extend and retain the outer peripheral portion of the apron away from the exterior perimeter of the bowl. Once installed, the apron is able to contain at least a portion of fluids that flow from the bowl through the space. The present invention also provides a method of servicing an aircraft lavatory between flights and a kit for use in servicing an aircraft lavatory.

Claims

1. A method for the containment of fluids that flow from a bowl of a commode installed in an aircraft lavatory through a space between a rim of the bowl and a shroud positioned above the rim, the method comprising:

providing an apron, the apron comprising a sheet having an opening formed in a central portion thereof and a plurality of fastening points formed in an outer peripheral portion thereof;

securing the central portion of the apron against an exterior perimeter of the bowl; and

fastening the plurality of fastening points to fixed anchors to thereby extend and retain the outer peripheral portion of the apron away from the exterior perimeter of the bowl, wherein at least a portion of fluids that flow from the bowl through the space between the rim of the bowl and the shroud positioned above the rim are contained by the apron.

2. The method according to claim 1 wherein the sheet is a flexible multilayer material comprising at least a first ply and a second ply, wherein the first ply comprises a fluid impermeable barrier ply and the second ply comprises an absorbent material.

3. The method according to claim 2 wherein the absorbent material is treated with an anti-microbial agent.

4. The method according to claim 1 wherein the central portion of the apron is secured against the exterior perimeter of the bowl using a band of aluminum.

5. The method according to claim 1 wherein the fastening points formed in the outer peripheral portion of the apron are reinforced by grommets.

6. The method according to claim 1 wherein the central portion of the apron is secured against the exterior perimeter of the bowl proximate the rim.

7. The method according to claim 1 wherein the apron is provided with at least one drain port for permitting at least a portion of the fluids that flow from the bowl through the space between the rim of the bowl and the shroud positioned above the rim to be directed through the drain port to a collection point.

8. The method according to claim 7 wherein the collection point comprises a supply of disposable absorbent material positioned in a predetermined location beneath the shroud.

9. The method according to claim 1 further comprising installing a disposable floor covering on a floor of the lavatory, the disposable floor covering comprising a moisture impermeable base that contacts the floor, a perforated top for supporting the weight of a user of the lavatory, and an absorbent portion disposed between the moisture impermeable base and the perforated top.

10. The method according to claim 9 wherein the disposable floor covering is unitary.

11. The method according to claim 9 further comprising laying a supplemental lavatory service pad on the disposable floor covering, the supplemental lavatory service pad comprising a sheet of absorbent material joined to a moisture impermeable backing.

12. The method according to claim 1 wherein the apron is disposable.

13. A kit for use in servicing an aircraft lavatory comprising:

an apron, the apron comprising a sheet having an opening formed in a central portion thereof and a plurality of fastening points formed in an outer peripheral portion thereof, the opening being arranged such that the central portion of the apron can be secured against an exterior perimeter of a bowl of a commode installed in the aircraft lavatory, and the plurality of fastening points being arranged such that they can be fastened to fixed anchors to thereby extend and retain the outer peripheral portion of the apron away from the exterior perimeter of the bowl.

14. The kit according to claim 13 wherein the sheet is a flexible multilayer material comprising at least a first ply and a second ply, wherein the first ply comprises a fluid impermeable barrier ply and the second ply comprises an absorbent material.

15. The kit according to claim 14 wherein the absorbent material is treated with an anti-microbial agent.

16. The kit according to claim 13 further comprising a band of aluminum for securing the central portion of the apron against the exterior perimeter of the bowl.

17. The kit according to claim 13 wherein the fastening points formed in the outer portion of the apron are reinforced by grommets.

18. The kit according to claim 13 wherein the apron is provided with at least one drain port.

19. The kit according to claim 13 further comprising:

a supply of disposable absorbent material.

20. The kit according to claim 13 further comprising:

a disposable floor covering for placement on a floor of the lavatory, the disposable floor covering comprising a moisture impermeable base that contacts the floor, a perforated top for supporting the weight of a user of the lavatory, and an absorbent portion disposed between the moisture impermeable base and the perforated top.

21. The kit according to claim 20 wherein the disposable floor covering is unitary.

22. The kit according to claim 20 further comprising:

a supplemental lavatory service pad for placement on the disposable floor covering, the supplemental lavatory service pad comprising a sheet of absorbent material joined to a moisture impermeable backing.

23. A method of servicing an aircraft lavatory between flights comprising:

securing a central portion of an apron against an exterior perimeter of a bowl of a commode installed in the aircraft lavatory, the apron comprising a sheet having an opening formed in the central portion thereof and a plurality of fastening points formed in an outer peripheral portion thereof,

fastening the plurality of fastening points formed in the apron to fixed anchors to thereby extend and retain the outer peripheral portion of the apron away from the exterior perimeter of the bowl;

placing a disposable floor covering on a floor of the lavatory, the disposable floor covering comprising a moisture impermeable base that contacts the floor, a perforated top for supporting the weight of a user of the lavatory, and an absorbent portion disposed between the moisture impermeable base and the perforated top;

optionally, positioning a supplemental lavatory service pad on the disposable floor covering, the supplemental lavatory service pad comprising a sheet of absorbent material joined to a moisture impermeable backing; and

charging a supply of fluid to a holding tank that is in fluid connection with the commode.
