Freezable container for a cooler

Abstract

A freezable container includes a base portion and may include a lid. The base portion may include a cold-retaining medium layer and be configured to be freezable to maintain a chilled environment for stored content. The freezable container may be configured to fit inside an insulated container such as a cooler.

1 . A first enclosure removably disposed within a second enclosure, wherein the first enclosure includes: 
 a lid; and    a base portion operatively coupled to the lid, the base portion comprising a bottom portion integrally coupled to a sidewall portion wherein the bottom portion, sidewall portion, and lid together define a compartment, the base portion further comprising at least one layer formed from a cold-retaining medium adapted to be freezable.    
   
   
       2 . The first enclosure according to  claim 1  wherein the base portion comprises: 
 a first peripheral layer composed of a polymer;    a second peripheral layer composed of a polymer;    a third layer composed of a cold-retaining medium disposed between the first and the second peripheral layers; and    a bonding layer composed of an adhesive material disposed between the first and the second peripheral layers.    
   
   
       3 . The first enclosure according to  claim 1  wherein the base portion comprises: 
 a first peripheral layer composed of a polymer;    a second peripheral layer composed of a polymer;    a bonding layer composed of an adhesive material disposed between the first and the second peripheral layers;    a separate cold-retaining medium layer positioned adjacent to the first peripheral layer within the compartment.    
   
   
       4 . The first enclosure according to  claim 1  wherein the lid comprises: 
 a first peripheral layer composed of a polymer;    a second peripheral layer composed of a polymer;    a third layer composed of a cold-retaining medium disposed between the first and the second peripheral layers; and    a bonding layer composed of an adhesive material disposed between the first and the second peripheral layers.    
   
   
       5 . The first enclosure of  claim 2 , wherein the first polymer layer is formed from a thermoplastic material.  
   
   
       6 . A freezable enclosure comprising a lid and a base portion operatively coupled to the lid, the base portion comprising a bottom portion integrally coupled to a sidewall portion wherein the bottom portion, sidewall portion, and lid together define a compartment, the base portion further comprising at least one layer formed from a cold-retaining medium adapted to be freezable.
