Gallon jug insulation sleeve

Abstract

An insulation sleeve, also known on a koozy, is adapted to fit on a one-gallon jug to keep its contents insulated. The insulation sleeve can wrap about the one-gallon jug, keeping warm liquids inside the jug warmer longer than without the insulation sleeve, and keeping cold liquids inside the jug colder longer that without the insulation sleeve. The insulation sleeve could be made of a insulation material, such as neoprene. The insulation sleeve could be made out of a single material, or multiple materials. For example, the insulation sleeve could include a rubber base to help minimize wear through the base of the insulation sleeve.

1 . An insulation sleeve for a gallon-sized jug, comprising:
 an insulation material forming a body of the insulation sleeve;   a handle cutout operable to allow a handle of the jug to pass therethrough;   a nozzle cutout operable to allow a nozzle of the jug to pass therethrough; and   an openable and closable portion allowing the jug to be inserted and removed from the insulation sleeve.   
     
     
         2 . The insulation sleeve of  claim 1 , wherein the openable and closable portion is a zipper. 
     
     
         3 . The insulation sleeve of  claim 2 , wherein the zipper extends from the nozzle cutout down a portion of one side of the insulation sleeve. 
     
     
         4 . The insulation sleeve of  claim 2 , wherein the zipper extends around about three sides of the insulation sleeve proximate to a base of the insulation sleeve. 
     
     
         5 . An insulation sleeve for a gallon-sized jug, comprising:
 an insulation body operable to cover an exterior portion of the jug;   a handle cutout operable to allow a handle of the jug to pass therethrough;   a nozzle cutout operable to allow a nozzle of the jug to pass therethrough; and   a zipper allowing the insulation body to be opened to permit the jug to be inserted and removed from the insulation sleeve.   
     
     
         6 . The insulation sleeve of  claim 5 , wherein the zipper extends from the nozzle cutout down a portion of one side of the insulation sleeve. 
     
     
         7 . The insulation sleeve of  claim 5 , wherein the zipper extends around about three sides of the insulation sleeve proximate to a base of the insulation sleeve.
