Vacuum insulated bottle

Abstract

A vacuum insulated bottle utilizing a wide opening vacuum filler is disclosed. A thin walled liner is disposed in the interior of the filler and extends upwardly therefrom to form a narrow mouth opening to the lined interior for providing the pouring and thermal insulating characteristics of a narrow mouth vacuum filler bottle.

I claim: 
     
       1. 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 .Iadd.and .Iaddend.closely conforming to .Iadd.and .Iaddend.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.   
     
     
       2. 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.   
     
     
       3. 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. 
     
     
       4. 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. 
     
     
       5. 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.   
     
     
       6. The vacuum insulated bottle of claim 1 wherein said liner is thin walled to reduce conductive heat loss. 
     
     
       7. 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.   
     
     
       8. The vacuum insulated bottle of claim 1 wherein the liner is produced by blow molding. 
     
     
       9. The vacuum insulated bottle of claim 1 wherein the liner is heat welded to the jacket to prevent leakage into said cavity. 
     
     
       10. 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. 
     
     
       11. 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. .Iadd. 12. An insulated bottle for containing foodstuffs or the like comprising an outer case, a liner received within said outer case and spaced therefrom for a major portion of the depth of said liner, said liner having an outer configuration of substantially cylindrical shape and terminating at one end thereof in a constricted neck and defining a cavity adapted to receive foodstuffs or the like, a vacuum filler having a generally cylindrical configuration and an opening at one end thereof interposed between said outer case and the cylindrical portion of said liner, the upper end of said vacuum filler terminating contiguous to the juncture between said liner cylindrical portion and its neck, a body of insulating material received between a portion of said outer case and said neck, said body of insulating material having a configuration conforming generally in shape to said neck and terminating contiguous to the juncture of said neck and said liner cylindrical portion, said body of insulating material being formed with a recess therein for receiving and supporting the upper end of said vacuum filler. .Iaddend..Iadd. 13. An insulated bottle as set forth in claim 12 wherein the outer case comprises a generally cylindrical portion and a separate breast piece to which the upper end of the liner is affixed. .Iaddend..Iadd. 14. An insulated bottle as set forth in claim 12 wherein the body of insulating material comprises a foamed plastic formed from two pieces. .Iaddend.
