Abstract

A foldable insulated jacket for a beverage container is formed from the same material as that of the carton in which the beverages are sold. A plurality of the insulated jackets can be formed as a portion of the carton or as a separate item removable and separable along a perforated line. A layer of insulating material can be added to the material of the jacket to provide additional insulating properties for the jacket.

       3 . The foldable insulating jacket of  claim 1  wherein said sheet of material is paperboard. 
   
   
       4 . The foldable insulating jacket of  claim 1  wherein said sheet of material further includes a layer of insulating material. 
   
   
       5 . The foldable insulating jacket of  claim 2  wherein said plurality of insulating jackets are formed as a portion of said carton in a manner that allows an individual said insulating jacket to be removed while said other insulating jackets remain secured to said carton. 
   
   
       6 . The foldable insulating jacket of  claim 2  wherein said plurality of insulating jackets are arranged in alternatively upright and upside down positions.
