July 6, 1965 c. BRAMMING VACUUM BOTTLE HAVING FILLER WITH CLOSURE MOUNTING RING CEMENTED THERETO Filed 0G13. 25, 1962 INVENTOR Carl rammmg United States Patent O 3,193,126 VACUUM BOTTLE HAVING FILLER Wllil-I QLUSURE MUNTENG RlNG CEMENTEE THERETO Carl liramming, Nashville, Tenn., assigner to Aladdin Industries, Incorporated, Nashville, Tenn., a corporation of illinois Filed Oct. 25, 1962, Ser. No. 233,061 Claims. (Cl. 21S-13) This invention relates to vacuum bottles or the like and pertains particularly to the portion of such bottle whereby the mouth of the bottle is closed.

One object of the present invention is to provide a new and improved vacuum bottle having a stopper portion together with means for pushing the stopper portion into the mouth of the vacuum insulated ller or inner receptacle of thevacuum bottle without any tendency to push the filler downwardly relative to the protective jacket.

Thus, it is an object of the present invention to prevent any disturbance of the seal between the ller and the upper portion of the protective ja-cket due to the tightening down of the stopper, such disturbance of the seal having tended to permit leakage between the filler yand the upper portion of the jacket in some cases with prior constructions.

A further object is to provide a new and improved vacuum bottle of the foregoing character in which the upper portion of the protective jacket takes the form of a ring which is cemented or bonded to the neck portion of the filler to prevent any separation of the liller from the ring, the ring being formed with screw threads or the like whereby the stopper for the vacuum bottle may be tightened down.

Another object is to provide a new and improved vacuumy bottle of the foregoing character in which the ring is formed as a separate element of the protective jacket so that each replacement filler may be supplied with a new ring, securely cemented thereto.

A further object is to provide a new and improved vacuum bottle of the foregoing character in which the upper end of the ring is formed with a pouring lip, while the lower end of the ring is provided with a joint element adapted to engage the upper or collar portion of the protective jacket.

Another object is to provide a new and improved closure construction which avoids any possibility of leakage between the upper end of the filler and the protective jacket, while being economical and easy to manufacture.

Further objects and advantages of the present invention will appear from the following description, taken with the accompanying drawing, in which the single figure is a longitudinal section of a vacuum bottle to be described as an illustrative embodiment of the present invention.

Thus, it will be seen that the drawing illustrates a vacuum bottle 1 which is of the usual type having a vacuum insulated filler or receptacle 2 which is received within a protective jacket 3. The ller 2 has inner and outer walls 4 and 5 with an evacuated space 6 therebetween. At its upper end, the filler 2 has a neck portion 7 of reduced diameter. A mouth 8 is formed in the upper end of the filler 2. The inner and outer walls d and 5 are joined together at the upper end of the iiller 2 to form a rounded rim portion 9.

At its lower end, the ller 2 may have a fragile tubulation 1i?, projecting downwardly therefrom, constituting the sealed remainder of the tube whereby the space 6 was evacuated during the process of manufacture. The tubulation 1t) is preferably protected from breakage by being enclosed within a generally cup-shaped protector 12, cemented to the lower end of the filler 2.

The illustrated protective jacket 3 is made principally of metal, but plastics or other suitable materials may be ernployed. In this case, the jacket 3 comprises a generally cylindrical side wall 13 to which a bottom wall 1d -is secured. A collar 15 is mounted on the upper end of the side wall 13. Normally, the jacket 3 is constructed so that it may be taken apart to provide for replacement of the iiller 2, if the filler should be broken. In this instance, .the collar 15 has a threaded lower portion 16 which is yadapted to be screwed into a threaded ring 17 which is secured to the upper end of the side wall 13. Thus, the collar 15 is readily removable from the side wall 3. It will be understood that the bottom of the jacket 3 might be removable, in which case the collar could be permanently connected to the side wall. Various other arrangements could be employed to provide for removal and replacement of the ller.

in this case, the collar 15 is formed with external threads 18 to mate with internal threads 19 on a cup Ztl which may be mounted in an inverted position on the upper end of the protective jacket to cover the upper end of the ller 2 and the upper portion of the collar 15. When removed from the vacuum bottle, the cup 20 serves as a drinking cup into which the beverage or other liquid in the vacuum bottle may be poured. The cup 20 may be made of plastic or any other suitable material.

The lower end of the filler 2 may be resiliently supported in the manner disclosed and claimed in the Carl Bramrning Patent No. 2,963,187, patent December 6, 1960, and entitled Filler Support for Vacuum Bottles. Thus, the tubulation protector 12 is preferably supported by a resiliently compressible sleeve 21 made of rubber, synthetic rubber, or other rubberlike material. The sleeve 21 is adapted to be compressed between an upwardly facing seat member 22 and a downwardly facing shoulder 23 on the tubulation protector 12. As shown, the seat member 22 is received and reta-ined within `a depressed portion 24 in the center of the bottom wall 14. The seat member 22 may be made of plastic or other suitable material. When the filler 2 is pressed downwardly, the rubber sleeve 21 bulges outwardly and acts as a spring member to aiord resilient .support for the filler.

To close the mouth 8, the vacuum bottle is provided with -a closure member 23 comprising a downwardly tapering hollow stopper portion 26 adapted to be received in the mouth 8. It will be evident that the stopper port-ion 26 forms a primary seal with the mouth 8. To form a further seal with the rim portion 9, the illustrated stopper 26 is provided with an outwardly flaring shoulder 27 near its upper end. The stopper 26 is preferably made of a resilient plastic material, such as polyethylene, polypropylene or the like.

To secure the closure 25 on the vacuum bottle, the illustrated closure is formed with a mounting neck portion 2S, which may comprise a cylindrical member or ange 29 projecting upwardly from the lshoulder 27, a generally horizontal ange 36 projecting outwardly from the upper end of the cylindrical member 29 and a depending cylindrical flange 31 projecting downwardly from the outer edge of the horizontal flange Si). All of the ilanges 29, 3i) and 31 may be formed integrally with the stopper portion 26. The depending outer flange 31 may serve as a hand grip for holding and manipulating the closure 25. In order that the closure 25 may be tightened down on the vacuum bottle, the inside of the outer ange 31 may be formed With internal screw threads 32 or other similar elements. A cavity 33 may be formed within the hollow stopper portion 26. The cavity 33 may be closed at its upper end by a generally disk-shaped closure 34 adapted to be snapped into the upper end of the cylindrical wall 29. If desired, the cavity 33 may be filled with an insulating material such as ground cork or the like.

To provide means for mounting the closure 25 on the vacuum bottle, a ring 35 is connected to the upper-end of the protective jacket 3. As shown, the ring 35 is made of plastic but other suitable materials may be employed. In the illustrated construction, the ring 35 has a generally cylindrical body portion 36 which is mounted around the upper portion of the neck 7 of the filler 2. VExternal screw threads 37 may be formed on the cylindrical portion 36 to mate with the internal screw threads 32 on the closure 25. As shown, an annular ange 38 projects inwardly from the upper end of the cylindrical body portion 36 so as to overhang-the rim 9 in the tube of the iller 2. An upwardly projecting pouring lip 39 may be formed on the inner edge of the ange 38, to provide for smooth pouring of liquids from the Vacuum bottle, while minimizing the tendency of liquids todrip or ilow down the outside of the protective jacket. Below and within the pouring lip 39, a flange 40 projects downwardly from the ange 38 for engagement with the curving rim 9 of the lter 2. In accordance with the present invention, the mounting ring 36 is retained on the upper end of the filler 2 in a secure and substantially permanent manner by resilient supporting member 21 insures that the ange 43 on the lowerv end` ofthe ring 35 will be pressed upwardly against the ange 44 on the upper end ofthe collar 15. y

The compression of the resilient supporting member 21 is` produced by the tighteningl ofthe collar 15 when the vacuum bottle is assembled. If the ller 2 is broken, it

may be replaced by unscrewing the collar 15, removing the remains of the Ybroken filler, inserting a new filler, and

means of a body or layer of suitable cement or adhesive v 41 disposed between the ring 35 and the neck portion 7 of the filler 2. YThe cement 41 forms a bond/with both the ring 35 and the ller 2 so as to prevent the ring 35 from separating from the liller. Thus, the cement 41 prevents any possiblity of leakage between the filler 2 and the ring 35. To interlock with the body of adhesive 41, the ring 35V may be provided with an internally projecting annular bead or ridge 42. i

The lower end of the ring 35 is connected to the upper end ofr the protective jacket 3 so that the ring 35 actually constitutes the upper portion of the jacket. lower end of the illustrated ring 35 is formed with an outwardly projecting upwardly facing shoulder or flange 43 adapted to interlock with an inwardly projecting annular ange 44Von the collar 15. It will be seen that the inwardly projecting liange 44 is hooked or slanted downwardly while the outwardly projecting iiange 43 is slanted upwardly to matewith the flange 44. In the use of the vacuum bottle, the closure may be screwed down tightly onto the vacuum bottle without causing any separation between the upper end of the filler 2 andthe ring 35, despite the downward force exerted by the stopper 26 upon the ller. The cement 41 resists the tightening force exerted'by the closure 25 and prevents any movement between the ring 35 and the ller. It will be realized that the threads 32 son the closurer25 pull 'upwardly on the ring 35, while the stopper 26 pushes downwardly onV theY liller` 2. However, the cement 41 prevents any movement bctweenthe ringv and the ller, due to these forces, and thus prevents any disturbance to the seal between the ring and the ller. With certainl prior constructions, `it has been found that the tightening of thel closure tends to push the ller downwardly relative to the protective jacket. Such movement of the ller disturbs the seal between the fillerV and the upper end of the 'pro- Such disturbance of the seal may causej tective jacket. leakage of liquids into the space between the filler and the protective jacket when liquids are subsequently poured out of the vacuum bottle. The present construction also provides a tighter seal between the stopper 26 and the mouth of the filler Zby insuring that the filler will not move downwardly under the sealing pressure exerted by the stopper.

The resilient supporting member 21 exerts a constant upward supporting force on the ller 2 so'as'to prevent any looseness of the filler within the protective jacket. The spring action of the resilient member 21 is adapted to compensate for the use of'llers varying slightly in length.

Such variations are often noted between different fillers' made by ordinary manufacturing techniques, despite efforts to hold all Vof the llers to the same length.V The replacing the collar. Each new filler is supplied with a new ring 35, which isV cementedto the ller at the factory to insure that the ring will be securely and permanently bonded to the filler. It will be recognized that the cost of the ring 35 is extremely small so thatit'is economical to supply a new ring with each filler.

The present invention positively prevents leakage of liquid between the ller and the upper end of the protective jacket so that there is no danger that the inside of the jacket will be corroded by the action of the liquid. Moreover, the present invention provides an improved seal between the stopper and the mouth of the ller. Various modifications, alternative constructions and equivalents may be employed without departing from the true Vspirit and scope of the invention, as exemplilied in the foregoingV description and defined in the following claims.
