GEORGE P. ALTENBERG, OF CINCINNATI, OHIO, ASSIGNOR TO THE ICY-HOT BOTTLE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF WEST VIRGINIA.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed March 9, 1917. Serial No. 153,735.

To all whom it may concern Be it known that I, GEORGE P. ALTEN- BERG, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Vacuum- Insulated Bottles and Cups The'refor, of which the following is a specification.

Vacuum insulated bottles as heretofore usually made comprise a single cap used as a drinking cup, the neck of the bottle and the cup being provided with complemental securing means for releasably securing the cup to the bottle.

t is the object of my invention to provide an attachment whereby a plurality of cups may be employed in connection with the bottle, and further to so arrange a bottle of the character mentioned that either a single cup or a plurality of cups may be bottle in this specification in its broader sense, as a container, regardless of its particular form.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a side elevation'of a vacuum bottle as heretofore constructed, provided with a single cup, and partly broken away and partly in axial section.

Fig. 2 is a side elevation exemplifying a vacuum-insulated bottle employing my invention, partly broken away and partly in axial section in the plane of the line 2--2 of Fig. 3.

Fig. 3 is a cross-section of the same in the plane of the line 3-3 of Fig.2; and,

Fig. 4.- is a cross-section of the same in the plane of the line 1-4 of Fig. 2.

My invention relates primarily to socalled vacuum-insulated bottles, and the bottle exemplified is a bottle of this character. It is instanced as comprising a vacuuminsulated vessel 11, comprising an inner wall 12 and an outer wall 13, said walls having a vacuum-insulated space 14 between them,

and being connected at their mouths by a cross-seal, as shown at 15. This vessel is a frangible vessel, being usually made of glass. It is adapted to be closed by a stopper 16.

A protecting casing is provided for the vessel, instanced as a casing -18, of sheet metal, comprising a body portion 19 having the casing is exemplified as threaded, as

preferably provided b shown at 27, and is above the threads with an annular substantially cylindrical reduced portion 28 from the upper end of which the sheet metal of the neck is bent inwardly in the form of a radial annular flange 29 projecting toward the neck of the bottle.

The vessel is suitably cushioned and securely held in the casing, as by means of a thimble 31 surrounding the neck 32 of the vessel and resting on the breast 33 of the vessel, a cushion ring 34, instanced as of rubber, being between the thimble and the flange 29, and a conical spiral spring 35 having a cushioning pad 36 thereon, instanced as of felt, being located between the bottom of the vessel and the bottom of the casing.

As heretofore usually constructed, a sin le cap, instanced at 39, is received over t e mouth of the vessel and the stopper therein, and has releasable connecting means with the neck of the casing. These connecting means are instanced as the screw-threaded portion 27, and a complemental screwthreaded portion 40 of the cap 39, the cap being arranged to be employed as a cup, into which the contents of the bottle may be poured for drinking the same.

The mouth of the neck of the vessel preferably protrudes above the radial flange 29, the radial flange and the annular smooth portion 28 thereunder serving as a pouring lip for preventing the flow of liquid contents of the vessel along the bottle when serving the same.

In order to provide for the employment of a plurality of cups in connection with the bottle, I provide a ring or thimble about the neck of the casing, and an outer cup, the said ring and outer cup being provided with complemental attaching means for releasably securing the outer cup to the ring over inner cups.

Instancing this arrangement, I have provided a rin 43, the inner face of which is provided with threads 44 arranged to be received over the threads-27 of the neck of the casing, the ring being provided with outer threads with which threads 46 of the outer cup 47 coact, for securing the outer on to the ring. 'The ring is preferably provi ed with an annular apron portion 48, which coacts with the breast 26 of the casing. The upper edgeof the ring preferably forms an annular support 49 which, when the ring is screwed in place, is preferably below the level of the top of the neck of the casing and forms a support for the inner cup or cups.

I have shown a plurality of inner cups, instanced as a nest of cups 51, 52 and 53, telescopical y arranged, and each provlded at its mout with an annular bead 54, the mouth of the lower cup, whenthe cups are inverted, resting upon the annular supporting face 49 and being received about the upper end of the neck of the casing for pos tioning the inner cups. The outer cup 18 arranged to be received inverted over the inner cup or cups, and to be 'releasably secured to the ring, preferably in such manner as to hold the inner cups firmly in place, although a different number of inner cups may be employed. For this purpose the outer thread portion of the ring and the thread portion of the outer cup are sufficiently long axially of the bottle, so that the outer cup may be screwed to greater or less extent downwardly upon the outer threads of the ring, clamping the inner cups in place between the normal bottom of said outer cup and said shoulder 49.

The ring is preferably held to the casing with a greater resistance to removal than is the outer cup. For accomplishing this purpose, an annular cushion 56 is instancedas interposed between the ring and the casing. This annular cushion may be instanced as a rubber ring received in an annular recess 57 in the ring 43, so that when the ring 43 i screwed in place on the casing, the cushion will cause a pressure between the threads of the ring 43 and the threads of the neck of the casing for resisting ready detachment of the ring 43, the annular cushion also aiding in exerting friction between the breast of the casing and the ring 43. When it is desired to 'remove the outer cup, the outer cup not being subjected to such resistance or friction, will bemore readily released than the ring, so that the ring will stay in place during use of the bottle.

In its preferred form, however, the ring may, if desired, be removed, so that either the single cup or the ring and plurality of cups may be employed in connection with the use of the bottle. a

The ring is instanced as formed up out of sheet metal and comprising an inner wall 58 and an outer wall 59, the threads 44, 45 being formed as rolled threads in these revbeing spective walls, and the walls being connected by an upper wall 60, forming the support for the nest of cups.

The apron portion of the ring is shown as provided with an annular knurled portion 61. The annular recess for the reception of the annular cushion 56, is shown formed by bending the lower end of the inner wall outwardly as a flange 62, the outer periphery of which is received in the annular groove 63 formed in the inner face of the outer wall of the ring 43, at the knurled portion thereof.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
