Converter base for a tumbler

Abstract

A converter base for use in connection with a tumbler, such as an insulated tumbler. The converter base has internal features that allow the base to convert the tumbler into a holder/cooler for differently-sized beverages. The converter base may also be provided with a built-in cooling feature.

1 . A converter base positionable in a tumbler, the converter base comprising:
 an open top end,   a closed base end, and   at least one internal feature that allows the converter base to receive differently-shaped beverage containers, the at least one internal feature comprising three or more inward ledges, wherein each inward ledge of the three or more inward ledges has a different diameter to support the differently-shaped beverage containers.   
     
     
         2 - 3 . (canceled) 
     
     
         4 . The converter base of  claim 1 , wherein a first inward ledge of the three or more inward ledges is configured to support a base of a first-shaped beverage container, and wherein a perimeter around the base end is configured to support a base of a third-shaped beverage container. 
     
     
         5 . The converter base of  claim 4 , wherein the perimeter has a first diameter, wherein the first inward ledge has a second diameter, and wherein the first diameter is larger than the second diameter. 
     
     
         6 . The converter base of  claim 1 , wherein the at least one internal feature is defined by a narrowing diameter. 
     
     
         7 . The converter base of  claim 1 , further comprising a cooling feature. 
     
     
         8 . The converter base of  claim 7 , wherein the cooling feature is positioned in a lower compartment. 
     
     
         9 . The converter base of  claim 7 , wherein the cooling feature is configured to be frozen in order to cool a beverage held by the converter base. 
     
     
         10 . The converter base of  claim 1 , further comprising a beverage securing lid. 
     
     
         11 . A method for using the converter base of  claim 1 , comprising:
 positioning the converter base into the tumbler;   positioning a beverage container within the converter base; and   positioning a beverage securing lid over the beverage container.   
     
     
         12 . The method of  claim 11 , further comprising, before positioning the converter base into the tumbler, cooling or freezing the converter base. 
     
     
         13 . A beverage container insulator system comprising:
 (a) a beverage container insulator configured to receive a plurality of beverage containers including a first beverage container of a first size and a second beverage container of a second size; and   (b) a converter base configured to be positioned in a bottom portion of the beverage container insulator, the converter base including a surface configured to space the first beverage container away from the bottom portion, the surface comprising three or more inward ledges, wherein each inward ledge of the three or more inward ledges has a different diameter to support the differently-shaped beverage containers.   
     
     
         14 . The beverage container insulator system of  claim 13 , further comprising a cover, the cover including an opening through which at least one of the first beverage container and the second beverage container can pass. 
     
     
         15 . The beverage container insulator system of  claim 14 , wherein at least an external surface of the converter base has a cylindrical shape and is sized to be received in the bottom portion of the beverage container insulator. 
     
     
         16 . The beverage container insulator system of  claim 15 , wherein the beverage container insulator system is configured such that the first beverage container rests on the surface when the converter base is positioned in the bottom portion of the beverage container insulator and the first beverage container is received in the beverage container insulator.
