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.

A multiple-layered hat for storing a dispensable fluid therein comprising:
- upper and lower layers of material innerconnected to form a fluid retaining cavity therebetween;
- a discharge port formed in the surface of at least one of said layers;
- at least one ventilation port formed in the surface of one of said layers to facilitate discharge of fluid through said discharge port directly into the mouth of a person using the hat without the need to remove the hat from the user's head;
- and
- a thermal exchange unit disposed substantially within said cavity, said thermal exchange unit comprising a substance having a temperature different than that of the beverage, such that thermal energy is transferred between said substance and fluid within said cavity, said thermal exchange unit being shaped to a form retractably disposable within said cavity.
