Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
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.
Claim 2
Dependent Claim
136 words
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.
Claim 3
Dependent Claim
24 words
The hat as recited in claim 1 wherein said thermal exchange unit comprises a molded plastic container having a volume of chilled refrigerant therein.
Claim 4
Dependent Claim
23 words
The hat as recited in claim 1 wherein said upper and lower layers of material form opposing surfaces of a molded, integral body.
Claim 5
Dependent Claim
45 words
The hat as recited in claim 1 wherein said thermal exchange unit comprises a sealed container having a volume of freezable refrigerant disposed therein, said container having an outer surface in contact with fluid within said cavity, said outer surface being formed of nontoxic material.
Claim 6
Dependent Claim
25 words
The hat as recited in claim 1 wherein said upper and lower layers are formed so as to define at least one fluid reservoir therebetween.
Claim 7
Dependent Claim
34 words
The hat as recited in claim 1 wherein said thermal exchange unit further comprises an upper surface portion disposed in substantially fluid tight engagement with an aperture formed in said upper layer of material.
Claim 8
Dependent Claim
44 words
The hat as recited in claim 1 wherein said thermal exchange unit comprises a casing having an open upper portion, said casing being adapted to receive a volume of chilled material therein, said chilled material being effective to cool the fluid within said cavity.
Claim 9
Dependent Claim
39 words
The hat as recited in claim 1 further including a length of tubing and a mouthpiece, said tubing having a first end in fluid communication with said discharge port, and a second end in fluid communication with said mouthpiece.
Claim 10
Dependent Claim
33 words
The hat as recited in claim 8, further including a valve formed in said mouthpiece, said valve being effective to regulate the flow of fluid from the fluid retaining cavity through the mouthpiece.
