Fitted bedsheet with integral waterproof layer

Abstract

The disclosed device is a fitted sheet, or what is commonly known as a bottom sheet, with a permanently-affixed and integral absorbent and waterproof layer that is used to cover a mattress. The result is a fitted sheet that, when wet, can be quickly and easily replaced as a single part.

What is claimed is: 
     
         1 . A waterproof fitted sheet to protect the top of a mattress, the waterproof fitted sheet comprising:
 a. a bedsheet made up of the following layers:
 i. an upper cotton sheet including:
 1. a top layer; 
 2. one or more side layers; and 
 3. a bottom layer; 
 
 ii. a permanently affixed waterproof layer including:
 1. an upper cotton layer; 
 2. a waterproof material layer bonded to the upper cotton layer; 
 3. a lower cotton layer bonded to the waterproof layer; 
 
 iii. the permanently affixed waterproof layer sized to cover only the top of the mattress; 
 iv. the top layer of the upper cotton sheet sewn to the permanently affixed waterproof layer; 
 v. whereby during use the permanently affixed waterproof layer is hidden by the upper cotton sheet. 
   
     
     
         2 . The waterproof fitted sheet of  claim 1 , whereby:
 a. liquids that are spilled on the top layer are absorbed by the upper cotton layer of the permanently affixed waterproof layer,   b. the liquids move through the upper cotton layer toward the waterproof material layer, and   c. the liquids do not move past the waterproof material layer leaving the upper cotton sheet and the mattress protected from the liquids.   
     
     
         3 . The waterproof fitted sheet of  claim 1 , further comprising:
 a. elastic banding along a perimeter of the bottom layer of the upper cotton sheet;   b. whereby the elastic banding helps maintain the position of the waterproof fitted sheet with respect to the mattress.   
     
     
         4 . The waterproof fitted sheet of  claim 1 , whereby the upper cotton layer absorbs liquid away from the upper cotton sheet by pulling liquid toward the waterproof material layer, the waterproof material layer then preventing liquids from reaching the mattress. 
     
     
         5 . The waterproof fitted sheet of  claim 1 , wherein the waterproof material layer is rubber. 
     
     
         6 . The waterproof fitted sheet of  claim 1 , wherein the waterproof material layer is plastic. 
     
     
         7 . A device with a permanently bonded layer that protects a mattress from a child's urine, the device comprising:
 a. a fitted sheet including:
 i. a top layer; and 
 ii. a side layer; 
   b. an integral absorbent and water-repelling layer;
 i. the integral absorbent and water-repelling layer permanently affixed beneath the top layer of the fitted sheet; 
 ii. the integral absorbent and water-repelling layer constructed from two layers of cotton-flannel material bonded to cover a top and a bottom of the water-repelling layer. 
   
     
     
         8 . The device of  claim 7 , whereby the cotton flannel absorbs liquid away from a bed sheet pulling liquid toward the water-repelling layer, the water-repelling layer then preventing liquids from reaching the mattress. 
     
     
         9 . The device of  claim 7 , wherein the water-repelling layer is rubber. 
     
     
         10 . The device of  claim 7 , wherein the water-repelling layer is plastic. 
     
     
         11 . The device of  claim 7 , further comprising:
 a. elastic banding along a perimeter of the bottom layer of the upper cotton sheet;   b. whereby the elastic banding helps maintain the position of the waterproof fitted sheet with respect to the mattress.   
     
     
         12 . A mattress protecting device to insulate a mattress from spills, the device drawing liquid away from a child, the device consisting of the following layers:
 a. a first layer formed from cotton;   b. a second layer formed from cotton flannel;   c. a third layer formed from a water-proof material;   d. a fourth layer formed from cotton flannel;   e. the second, third, and fourth layers permanently bonded to one-another, then sewn to the first layer.   
     
     
         13 . The mattress protecting device of  claim 12 , whereby liquids spilled on the first layer are absorbed by the second layer and pulled toward the third layer leaving the first layer dry, the third layer then preventing liquid from reaching the mattress. 
     
     
         14 . The mattress protecting device of  claim 12 , whereby the cotton flannel absorbs liquid away from a bed sheet pulling liquid toward the water-proof layer, the water-proof layer then preventing liquids from reaching the mattress. 
     
     
         15 . The mattress protecting device of  claim 12 , wherein the water-proof layer is rubber. 
     
     
         16 . The mattress protecting device of  claim 12 , wherein the water-proof layer is plastic.
