Abstract: An insulated beverage container holder includes a cylindrical hollow body portion connected to a cylindrical hollow cap by an integrally molded flexible plastic loop hinge. A hollow cylindrical insulating foam liner cup is dimensioned for removable insertion into the cylindrical body. The hollow interior of the liner cup is dimensioned to removably receive standard sized beverage containers, such as cans and bottles. An upstanding annular ledge on the open upper end face of the body cooperates with an annular step provided on the bottom end face of the cap to form a frictional closure. A thumb catch disposed on the cap, diametrically opposite the hinge, facilitates manual opening and closing the cap. A disk-shaped, thin, cylindrical end plate is integrally molded as a component of said cylindrical body proximate a bottom end face of the hollow body. The end plate forms a floor which supports a bottom surface of the liner cup.
