ABSTRACT:
A multi-layered hat is disclosed for storing a dispensable fluid therein. The hat comprises upper and lower layers of material interconnected to form a fluid retaining cavity therebetween. A discharge port and ventilation port are formed in the surface of the layers to facilitate discharge of the beverage to a fluid conduit, the other end of which may be placed in the mouth of the user. A thermal exchange unit, such as a frozen refrigerant encased in non-toxic plastic material, is disposed substantially within the cavity, and is adapted to transfer thermal energy between the refrigerant and the fluid stored in the cavity.
