Pet sheet

Abstract

Disclosed is a pet sheet including a backsheet, a liquid-permeable topsheet and a liquid absorbent layer which is smaller than the backsheet and disposed between the backsheet and the topsheet. The backsheet extends beyond the liquid absorbent layer to provide side regions outside the liquid absorbent layer. A hydrophilic sheet is provided above the backsheet in the side regions.

1 . A pet sheet comprising a backsheet, a liquid-permeable topsheet and a liquid absorbent layer which is smaller than the backsheet and disposed between the backsheet and the topsheet, wherein 
 the backsheet extends beyond the liquid absorbent layer to provide side regions outside the liquid absorbent layer and a hydrophilic sheet is provided above the backsheet in the side regions.    
   
   
       2 . A pet sheet according to  claim 1 , wherein both the backsheet and the liquid absorbent layer are rectangular and the side regions are provided along all four sides of the liquid absorbent layer.  
   
   
       3 . A pet sheet according to  claim 1 , wherein in the side regions, the hydrophilic sheet is laid on the backsheet.  
   
   
       4 . A pet sheet according to  claim 3 , wherein the topsheet extends beyond the liquid absorbent layer to cover the hydrophilic sheet in the side regions.  
   
   
       5 . A pet sheet according to  claim 1 , wherein the hydrophilic sheet extends between the liquid absorbent layer and the topsheet and beyond the liquid absorbent layer into the side regions.  
   
   
       6 . A pet sheet according to  claim 1 , wherein in the side regions, the topsheet is located between the backsheet and the hydrophilic sheet.  
   
   
       7 . A pet sheet according to  claim 1 , wherein the topsheet is an apertured resin film, the liquid absorbent layer is an absorbent core covered with a tissue paper, and the hydrophilic sheet is a nonwoven fabric that is greater in both thickness and basis weight than the tissue paper.  
   
   
       8 . A pet sheet according to  claim 7 , wherein the nonwoven fabric is in contact with the liquid absorbent layer.
