Abstract: An insulated modular vessel for transporting beverage containers of a known size and shape, typically cans and bottles, is disclosed. The insulated modular vessel comprises at least one main body portion having first and second open ends and generally cylindrically shaped peripherally disposed outer wall extending between the first and second ends so as to define a centrally disposed cavity shaped and dimensioned to receive and retainer beverage containers therein. An insulating layer is disposed generally around the perimeter of the main body portion. The first and second open ends are shaped and dimensioned to permit the passage of beverage therethrough into and out of the centrally disposed cavity. Co-operating male and female threads are disposed at the first and second ends respectively of the main body portion so as to permit a plurality of main body portions to be removably matably attachable to one another in first-end-to-second-end relation so as to form the modular vessel.
