Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
99 words
A vacuum insulated bottle comprising: a vacuum filler having a heat insulating interior for receiving material therein and having a relatively wide opening to said interior; a protective jacket disposed about said filler; a liner adjacent to closely conforming to disposed in the temperature insulating interior of said filler and extending upwardly therefrom to form a relatively narrow mouth opening to the lined interior, said liner being attached to the jacket at the liner''s upper end; and a collar formed of heat insulating material disposed in a cavity formed between the jacket and the liner near said wide opening.
Claim 2
Dependent Claim
99 words
A vacuum insulated bottle comprising: a vacuum filler having a heat insulating interior for receiving material therein and having a relatively wide opening to said interior; a protective jacket disposed about said filler; a liner adjacent to closely conforming to disposed in the temperature insulating interior of said filler and extending upwardly therefrom to form a relatively narrow mouth opening to the lined interior, said liner being attached to the jacket at the liner''s upper end; and a collar formed of heat insulating material disposed in a cavity formed between the jacket and the liner near said wide opening.
Claim 3
Dependent Claim
33 words
The vacuum insulated bottle of claim 1 further including: a stopper adapted to close said narrow mouth opening; and a cap engageable on said jacket for covering the stopper and narrow mouth opening.
Claim 4
Dependent Claim
53 words
The vacuum insulated bottle of claim 2 wherein said stopper extends into said interior to a position at or below the top of said liner thereby to define a fill level for said bottle which is at or below the top of said liner for optimizing the thermal insulating capability of the bottle.
Claim 5
Dependent Claim
27 words
The vacuum insulated bottle of claim 1 wherein the heat insulating material is a rigid foam adapted to support said liner near the top of the filler.
Claim 6
Dependent Claim
29 words
The vacuum insulated bottle of claim 1 wherein heat insulating material is selected from the group comprising: fluorocarbon expanded urethane foam, carbon dioxide expanded urethane foam, and polystyrene foam.
Claim 7
Dependent Claim
18 words
The vacuum insulated bottle of claim 1 wherein said liner is thin walled to reduce conductive heat loss.
Claim 8
Dependent Claim
30 words
The vacuum insulated bottle of claim 1 wherein said liner is selected from the group of materials comprising: polypropylene, ABS, acetal, polycarbonate, modified PPO, nylon, polysulphone, HDPE and polybutylene therathalate.
Claim 9
Dependent Claim
15 words
The vacuum insulated bottle of claim 1 wherein the liner is produced by blow molding.
Claim 10
Dependent Claim
22 words
The vacuum insulated bottle of claim 1 wherein the liner is heat welded to the jacket to prevent leakage into said cavity.
Claim 11
Dependent Claim
46 words
A thin walled liner providing a narrow mouth opening to a vacuum insulated bottle having a relatively wide opening vacuum filler, said liner adjacent to and closely conforming to the interior of said filler and extending upwardly and inwardly therefrom to form said narrow mouth opening.
Claim 12
Dependent Claim
46 words
A thin walled liner providing a narrow mouth opening to a vacuum insulated bottle having a relatively wide opening vacuum filler, said liner adjacent to and closely conforming to the interior of said filler and extending upwardly and inwardly therefrom to form said narrow mouth opening.
Claim 13
Dependent Claim
30 words
The vacuum insulated bottle of claim 9 wherein said liner is selected from the group of materials comprising: polypropylene, ABS, acetal, polycarbonate, modified PPO, nylon, polysulphone, HDPE and polybutylene therathalate.
