A thermal isolating sheath for the beverage containers, which is integrally made by a kind of flexible and elastic thermal isolating material, and is comprised of a main gasket and a base gasket. The main gasket is of suitable width and length, which may be closed to form a cylindrical shape by two buttons on both side edges thereof. The base gasket extended integrally from the midpoint on one edge of the main gasket may be defined as the base of the sheath by snapping up together the individual buttons disposed respectively on the appropriately angularly extending corner tabs thereof and the two buttons disposed on the main gasket; thereby a sheet of gasket layer is defined which may cover the periphery of a beverage container.
