exact text as granted — not AI-modified
1 . A powder dispensing pad, comprising:
 (1) a bottom barrier layer,   (2) a top barrier layer,   (3) a seal, circumferentially sealing the top and the bottom barrier layers,   (4) a storage layer, between the top and bottom barrier layers,   (5) a metering layer, having pores, between the storage layer and the top barrier layer, and   (6) a powder, between the bottom barrier layer and the top barrier layer.   
     
     
         2 . The powder dispensing pad of  claim 1 , further comprising holes in the top barrier layer, through which the powder may be dispensed. 
     
     
         3 . The powder dispensing pad of  claim 2 , further comprising:
 (7) a sealing layer, on the top barrier layer and covering the holes, and   (8) an adhesive layer, adhering the sealing layer to the top barrier layer.   
     
     
         4 . The powder dispensing pad of  claim 1 , further comprising a container, within which is the powder dispensing pad. 
     
     
         5 . The powder dispensing pad of  claim 4 , wherein the container is a plastic bag. 
     
     
         6 . The powder dispensing pad of  claim 2 , wherein the powder dispensing pad is folder in half, so that each half of the top barrier layer face each other, and a seal on the top barrier layer, for holding each half of the top barrier layer together. 
     
     
         7 . The powder dispensing pad of  claim 1 , further comprising a cover layer having a line of perforations. 
     
     
         8 . The powder dispensing pad of  claim 1 , wherein the powder is between the bottom barrier layer and the metering layer. 
     
     
         9 . The powder dispensing pad of  claim 8 , wherein the powder is between the storage layer and the bottom barrier layer. 
     
     
         10 . The powder dispensing pad of  claim 8 , wherein the powder is within the storage layer. 
     
     
         11 . The powder dispensing pad of  claim 8 , wherein an amount of the powder present is a unit dose.
