The present device relates generally to a bottom closure for an insulated sleeve-type beverage holder. The closure is composed of a rigid plastic material and is designed to be reliably affixed to the base of a tubular sleeve of insulating foam. In a preferred embodiment of the present device, the closure contains apertures therethrough to relieve vacuum and pressure conditions that might otherwise arise during the insertion and removal of a beverage container. On its upper side, the closure contains a plurality of circular ridges, the ridges possessed of an inside bevel, whose purpose is to improve the adhesion between the closure and the insulating sleeve. On its underside, the closure contains a short cylindrical sidewall which is designed to accept a removable storage portion, the storage portion adapting the insulated beverage holder to make it suitable for use in an automobile beverage holder. The sidewall contains indentations on its outer surface at a plurality of locations so as to allow unobstructed air flow into and out of the storage portion between the inner wall of the storage portion and the outer wall of the sidewall. The underside of the closure also contains a plurality of radial ribs which act to prevent the storage portion from making a tight seal with the underside of the closure. The dimensions of the storage portion are chosen so as to allow it to fit within the beverage holders found in most automobiles.
