Abstract

Disclosed is a bed pad having improved leakage protection provided by a folded absorbent structure. In one embodiment, the bed pad uses a stabilized absorbent material folded into a central channel, a pair of transversely disposed side margins, and a pair of transversely disposed side margins.

Claims

exact text as granted — not AI-modified
We claim:  
     
         1 . A bed pad comprising: 
 an absorbent structure disposed adjacent a bottomsheet, the absorbent structure having a stabilized absorbent material, and the absorbent structure is folded at least twice; and    the bed pad having a width W P , the absorbent structure having a width W A , and a ratio of W A /W P  is from about 0.2 to about 0.8.    
     
     
         2 . The bed pad of  claim 1  wherein the folded absorbent structure comprises a central channel and a pair of transversely disposed side dams adjacent the central channel.  
     
     
         3 . The bed pad of  claim 2  wherein the folded absorbent structure comprises a pair of oppositely disposed side margins adjacent the side dams.  
     
     
         4 . The bed pad of  claim 2  wherein the central channel has a width W C  and the width W C  is greater than about 200 mm.  
     
     
         5 . The bed pad of  claim 4  wherein the width W C  is greater than about 400 mm.  
     
     
         6 . The bed pad of  claim 1  wherein the ratio W A /W P  is from about 0.3 to about 0.6.  
     
     
         7 . The bed pad of  claim 1  wherein the bottomsheet and the absorbent structure are plied together prior to folding, and the folded portion is joined together by at least one adhesive bead.  
     
     
         8 . The bed pad of  claim 7  wherein the bed pad comprises a central channel and the width of the central channel is adjustable.  
     
     
         9 . The bed pad of  claim 1  further comprising a barrier layer disposed between the bottomsheet and the absorbent structure, and a topsheet disposed adjacent the absorbent structure.  
     
     
         10 . A bed pad having a central longitudinal axis and a central transverse axis comprising: 
 a center portion and a pair of transversely disposed side portions, the center portion having an absorbent structure disposed between a topsheet and a bottomsheet, and the side portions free of the absorbent structure;    the absorbent structure folded from an absorbent material into a central channel, and a pair of transversely disposed side dams adjacent the central channel, and    the central channel having a width W C  greater than about 200 mm.    
     
     
         11 . The bed pad of  claim 10  wherein the width W C  is greater than the width of a person's posterior when lying longitudinally on the bed pad.  
     
     
         12 . The bed pad of  claim 10  wherein the absorbent structure comprises a stabilized absorbent material.  
     
     
         13 . The bed pad of  claim 10  wherein the topsheet, the absorbent structure, and the bottomsheet are plied together prior to folding and the folded portion is joined together by at least one adhesive bead.  
     
     
         14 . The bed pad of  claim 13  wherein the width W C  is adjustable by pulling transversely on the side portions.  
     
     
         15 . The bed pad of  claim 10  wherein the absorbent structure further comprises a pair of oppositely disposed side margins adjacent the side dams.  
     
     
         16 . The bed pad of  claim 10  wherein the bed pad has a width W P  and the absorbent structure has a width W A  and a ratio of W A /W P  is from about 0.2 to about 0.8.  
     
     
         17 . The bed pad of  claim 10  wherein a barrier layer is disposed between the absorbent structure and the bottomsheet.  
     
     
         18 . A bed pad having a central longitudinal axis and a central transverse axis comprising: 
 a center portion and a pair of transversely disposed side portions, the center portion having an absorbent structure disposed between a topsheet and a bottomsheet, and the side portions free of the absorbent structure;    the absorbent structure folded from a stabilized absorbent material into a central channel, and a pair of transversely disposed side dams adjacent the central channel, and    the central channel having a width W C  greater than about 200 mm.    
     
     
         19 . The bed pad of  claim 18  wherein the stabilized absorbent material has a basis weight from about 100 gsm to about 1000 gsm.  
     
     
         20 . The bed pad of  claim 18  wherein the stabilized absorbent material has a density from about 0.1 g/cc to about 0.4 g/cc under a load of 0.35 kPa.  
     
     
         21 . The bed pad of  claim 18  wherein the stabilized absorbent has an absorbent capacity greater than about 8 g/g.  
     
     
         22 . The bed pad of  claim 18  wherein the side dams remain uncompressed when a person lays on the bed pad.
