Household bed covering for families with pets
A laminated bed covering has a puncture resistant outer layer, a waterproof but water vapor permeable central layer and an inner layer, the entire structure protecting the bed and bed clothing from dog claws, pet urine, and pet odors while providing a comfortable sleeping environment to the bed's occupants.
1. A waterproof, water-vapor-permeable bed covering for covering a sleeping bed adapted to protect the sleeping bed from household pets, said bed covering comprising at least the following three layers:
an inner layer being at least partially cotton;
a waterproof and breathable central layer having an inner face adjacent said inner layer and an outer face, said central layer permitting the transit of water vapor from said inner face to said outer face in a first direction, while preventing the transit of liquid water from said outer face to said inner face in a second direction;
said central layer is a fluoropolymer layer;
an outer layer being puncture resistant and at least partially cotton for providing wear resistance to a pet above said outer layer;
said bed covering being washable in a water based domestic home type washing machine; and,
wherein said inner layer, said central layer, and said outer layer permit said transit of said water vapor, in said first direction, traveling from an occupant between said sleeping bed and said bed covering, through first said inner, then said central layer, and finally said outer layer.
2. The bed covering of claim 1 wherein said central layer is laminated to said outer layer.
3. The bed covering of claim 1 wherein said outer layer has a thread count of at least 150 threads per square inch.
4. The bed covering of claim 3 wherein said outer layer is a plain weave fabric.
5. The bed covering of claim 4 wherein said outer cover has a thread count of about 330 threads per square inch.
6. The bed covering of claim 1 wherein said central layer is a polytetrafluoroethylene layer.
7. The bed covering of claim 6 wherein said central layer is an expanded polytetrafluoroethylene layer.
8. A waterproof, water-vapor-permeable bed covering for covering a sleeping bed adapted to protect the sleeping bed from household pets, said bed covering comprising at least the following three layers:
a fabric inner layer being at least partially cotton for providing comfort to an occupant below said inner layer;
a polytetrafluoroethylene waterproof and breathable central layer having an inner face adjacent said inner layer and an outer face, said central layer simultaneously
permitting the transit of water vapor from said inner face to said outer face while preventing the transit of liquid water from said outer face to said inner face;
a fabric outer layer being puncture resistant for providing wear resistance to a pet above said outer layer;
said bed covering being washable in a water based domestic home type washing machine; and,
said outer layer is a plain weave fabric containing cotton and having a thread count of at least 150 threads per square inch.
