FLEXIBLE VACUUM norm: CARRIER 1 Filed Nov. 9, 1953 INVENTOR. Kenna-u E. V\u

g gi wzm A True/v5 VS United States Patent 2,781,960 FLEXIBLE VACUUM BOTTLE CARRIER Kenneth E. Dick, Alameda, Califl, assignor to The Dicar Company, a copartnership Application November 9, 1953, Serial No. 390,937 1 Claim. (Cl. 224-45) This invention relates to a flexible vacuum bottle carrier and has for one of its objects the provision of a flexible carrier for a vacuum bottle that is economical to make, and that is adapted to lie flat against a side of the vacuum bottle when not in use, thus enabling the bottle to be packed in a conventional lunch box or to otherwise be conveniently stowed away, and which carrier may be engaged by one or more fingers of a hand, or

. secured to a belt or other support for carrying the bottle. Most vacuum bottles are broken due to dropping them, and most bottles are dropped because there is nothing on them for safely and easily holding them. The users either tuck a vacuum bottle under an arm when carrying it, or else attempt to grasp the relatively large cylindrical outer body in the hand. These are precarious ways of attempting to carry the vacuum bottle, and heretofore the attempts to overcome the trouble have been along the line of attaching a rigid handle to the bottle. Such handle destroys the compact feature of a vacuum bottle, with the result that it cannot be packed away as Was formerly the case, nor do rigid handles enable the user to carry more objects in one hand than the vacuum bottle.

With the present invention, the vacuum bottle can be safely carried by one finger only of the hand, of desired, leaving the rest of the fingers free to carry other objects,

and the bottle can be packed away as conveniently as before the carrier was added.

A further object of the invention is the provision of a carrier that can be readily attached to any conventional vacuum bottle without altering the bottle in any way, and which carrier has all of the advantages already enumerated. 7

Other objects and advantages will appear in the description and in the drawings.

In the drawings, Fig. l is an exploded perspective view of the elements of a vacuum bottle (except the cover cap) with the present invention shown in its relationship to the other elements.

Fig. 2 is a perspective view of a vacuum bottle, including the cap, with the present invention secured thereto.

Fig. 3 is a fragmentary View of a slightly different form of the invention.

In detail, referring to Fig. 1 a conventional vacuum bottle comprises a glass inner bottle 1 and a cylindrical outer body 2. One end of the outer body is open and this open end has an internally threaded collar 3 secured therein, which collar includes a portion 4 along one edge that is crimped to the outer body 2 along the edge of said open end of the latter so as to tightly secure the collar 3 to the body so as to virtually be integral therewith.

An externally threaded collar 5 is secured over the projecting neck of the vacuum bottle and the threads on this collar 5 are in engagement with the threads on collar 3, thus securing the bottle 1 within the body 2.

A radially outwardly projecting flange 7 on collar 5 is adapted to engage the crimped portion 4 of the collar 3 when the bottle 1 is in the proper position within the body 2.

The preferred form of the present invention comprises a ring 10 that is adapted to be clamped between the flange 7 and the upper edge of the body 2, or portion 4 that is on the latter. This ring can readily be secured between flange 7 and the body 2 by merely unscrewing collar 5 and slipping the ring over the threaded lower end 6 of said collar and then threading said lower end back into the collar 3.

Said ring 10 is slightly enlarged at one point 11 therearound, and this enlargement is formed with an opening through which a flexible element 12 extends. Element 12 can be a flexible strap of any suitable material, or a chain or the like, and it is preferably formed to provide a loop '13 through which one or more fingers of the hand of a person may be inserted.

The flexible element thereof may, if desired, be removed, since it may have a buckle 14 or the equivalent, and whether the element 12 is present or not, the projection 11 will prevent the bottle from rolling off a table or the like if it is laid on its side, thus the ring and the enlargement 11 will perform a desirable function should the strap or element 12 be removed.

The cap 15 (Fig. 2) can be readily placed on the vacuum bottle inasmuch as the ring 10 does not interfere in any way with any of the features of the bottle.

In certain instances, the collar 4 may be modified to provide a collar 16 as seen in Fig. 3. This collar 16 has a lip 17 integrally formed therewith, and said lip is apertured for securing a flexible element 18 corresponding to element 12 or its equivalent.

As has already been mentioned, the size of the strap 12 or flexible element, may be sufficient to extend over the shoulder of a person, or it may only be small enough to permit one or Several fingers to be extended therethrough. For the purpose of the present invention, it should be flexible.

I claim:

In combination with a vacuum bottle having a cylindrical outer body terminating in a circular edge at one end thereof and an inner bottle coaxial within said body, said inner bottle having a neck portion projecting outwardly of said one end of said outer body and the outer end of said neck portion being provided with a pouring month; an interiorly threaded section rigid with said outer body at said one end of said outer body, a collar separate from said inner bottle extending over and in engagement with said neck portion and in threaded engagement with said threaded section for releasably securing said inner bottle Within said outer body independently of a cap and closure for said inner bottle, said collar including a flange projecting radially outwardly and over the edge of said body at said threaded section,

said collar including a threaded portion at the side of said flange opposite to said threaded section for threaded connection with a cap; an annular member held coaxial with said body and held between said flange and said edge by said flange independently of such cap and said annular member being releasable from said collar upon removal of said collar from said threaded section, and a flexible element including a loop connected with said annular member at one side thereof and projecting therefrom providing means for connecting said body to a person for carrying said vacuum bottle by such person.
