Liner for an insulated container

Abstract

A removable container liner for a rigid insulating container includes a bottom portion and a wall portion formed as a single unitary body. The body may be composed of a stain resistant and odor resistant plastic. The liner may be configured to be used within an insulated container such as a cooler or water jug.

1 . A removable lining element configured to fit within a rigid insulated container, the lining element comprising: 
 a bottom portion;    a wall portion attached to the bottom portion;    a wall edge formed by an edge of the wall portion; and    a mouth for receiving content therein, the mouth being substantially coincident with an opening of the rigid insulated container.    
   
   
       2 . The removable lining element of  claim 1  comprising a rigid unitary body.  
   
   
       3 . The removable lining element of  claim 1  shaped to substantially follow the contours of an interior surface of the rigid insulated container.  
   
   
       4 . The removable lining element of  claim 1  configured for resisting stains and odors.  
   
   
       5 . The removable lining element of  claim 1  comprising a wall portion integrally formed to the bottom portion.  
   
   
       6 . The removable lining element according to  claim 1 , wherein the removable lining element is composed of a thermoplastic material.  
   
   
       7 . The removable lining element of  claim 6 , wherein the thermoplastic material is a Stain Shield™ polymer.  
   
   
       8 . The removable lining element of  claim 6 , wherein the thermoplastic material is a polycarbonate.  
   
   
       9 . The removable lining element of  claim 6 , wherein the thermoplastic material is a polyethylene terephthalate.  
   
   
       10 . The removable lining element according to  claim 1  being formed by an injection molding process.  
   
   
       11 . The removable lining element according to  claim 1  being formed by a blow molding process.  
   
   
       12 . The removable lining element according to  claim 1  being formed by a one-step blow molding process.  
   
   
       13 . The removable lining element according to  claim 1  wherein the bottom portion and the wall portion together define a rectangular prismatic cavity.  
   
   
       14 . The removable lining element according to  claim 1  wherein the bottom portion and the wall portion together define a cylindrical cavity.  
   
   
       15 . The removable lining element according to  claim 1  wherein the bottom portion and the wall portion together define a triangular prismatic cavity.  
   
   
       16 . The removable lining element according to  claim 1  wherein the bottom portion and the wall portion together define a trapezoidal prismatic cavity.  
   
   
       17 . The removable lining element according to  claim 1  wherein the rigid insulated container is a cooler.  
   
   
       18 . The removable lining element according to  claim 1  wherein the rigid insulated container is a portable liquid container.  
   
   
       19 . A method of resisting stain and odor within a rigid insulated container having an interior surface, comprising: 
 providing a removable rigid lining element; and    preventing content from contacting the interior surface of the rigid insulated container.    
   
   
       20 . The method of  claim 19 , wherein the removable rigid lining element is composed of a thermoplastic material.
