Specification of Letters Patent.

Patented Sept. 22, 1914.

Application led November 30, 1910. Y Serial No. 594,945.

T0 cZZ whom it may concern.'

Be it known that I, JACOB A. ULMAN, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Non-Refillable Bottles, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in non-reiillable bottles; it being the object of the present invention to provide a bottle of this class in which will be overcome a certain difficulty in pouring which develops undercertain conditions with certain liquids; this particular difficulty being the liability of the valve, notwithstanding the tilting of the bottle to pouring position, to remain seated and thus prevent the pouring of the contents of the bottle. `.bis a full understanding of the improvenients of the present invention can best be had from a detailed description of an organization embodying the same, such description will now be given in connection withV the accompanying drawings, in which- Figure 1 is a. vertical elevation of a bottle equipped with the present invention. Fig. Q is a vertical section of the same. Fig. 3 is a view similar to Fig. 2, with the bottle tilted to pouring position. Figs. 1, 5, G and T are sections on the lines 4L, 5, 6, 7 respectively, of Fig. 2; and Fig. 8 is a side elevation of part of the bottle neck.

The bottle here-illustrated is that shown and described in the application of Maurice Switzer and Joseph D. Lacroix, filed November 7, 1910, Serial No. 591,054 except for the additionthereto of one feature constituting the present invention and which will be hereinafter fully described. The following brief general description of the other features of the bottle will, therefore, be sufiicient.

Referring to said drawings, a represents the bottle body, terminating at its upper end in a neck portion b, to which is permanently secured by cement and otherwise a neck containing the valve and valve-controlling mechanism by which the bottle is rendered non-reiillable. The neck is, in the process of manufacture, made up of two parts c fl of porcelain, which, however, are so united by an outer film e of enamel and the interlocking engagement of their abutting and correspondingly shouldered edges as to become, in effect, a unit or integral, as described in said application of Switzer and Lacroix. The part c contains a valve seat f, of porcelain, chamfered at its lower outer edge to lit a correspondingly shaped shoulder provided by the inner upper edge of the neck portion Z) of the bottle body c, and at its upper edge fitting into a recess g in the lower end of part 0,' a hollow inverted cupshaped valve it, preferably of porcelain, resting on this valve seat; an approximately pear-shaped valve-seating weight i, of glass or porcelain, resting sidewise on the upper end of the valve Zz.; and a baffle y' which, among other things, limits the movement of weight integral vertical ribs f: being also formed in the neck part c for guiding valve ZL in its vertical or opening and closing movements. Batlle j, which is integral with the neck part eZ, closes the bottle neck except for a passage between it and the inner surface of the latter, into which, however, project two horizontal rows of alternating or staggered projections Z, m, which will permit the passage of the liquid contents of the bottle but will prevent the insertion of a wire or the like sufliciently far into the bottle neck to tamper with the valve Zt or weight z'. At the ends of each projection Z m are vertical ribs a, which it is obvious will engage the end of any wire or the like inserted in the bottle neck and prevent further downward movement thereof. The insertion of a wire or the like is still further guarded against by the provision of shoulders 0 in the neckportion o projecting inwardly beneath the projections Z, m, so that a wire cannot be passed between the outer ends of said projections and the inner surface of the neck into the lower end of part o containing the valve ZL. Baflie j is also provided at its lower end with a. recess p for the accommodation of weight z', this recess and the weight .2', valve 71 and seat f being of such size and so arranged relatively to each other as to provide for free rocking movement of said weight, and also a limited movement thereof, and of valve ZL longitudinally of the bottle neck.

lVhile the bottle is in an erect position, the valve 7L and weight z' will occupy the positions in which they are shown in Fig. 2, with the valve 7L held to its seat by its own weight and that of weight z'. W'hen, however, the bottle is tilted to pour out some of its contents, and passes from a horizontal portion to the partially inverted position shown in Fig. 3, the valve, relieved of the weight of weight z', which has moved into recess 7), and aided by the pressure of the liquid in the bottle, will be unseated and assume the position in which it is shown in Fig. 4f. On

turning the bottle upwardly, as soon as it.

passes a horizontal position, and approaches an erect position, weight z', rocking in recess p and moving downwardly at right angles to the bottle neck, will, as the liquid recedesV from the bottle neck, force valve L to its.

seat, aided, of course, by the weight of the valve itself.

The bottle neck, made in two parts c, d, united as described in said application of` Switzer and Lacroix, is secured to the bottle j 'body a by a collar r of suitable metal inclos- 1 ing the upper end of the neck portion Z) ofl the bottle body and the lower portion of the neck member c, both of which portions are provided with circumferential indentations or recesses, into which the metal of collar r is forced or spun by a suitable tool. To prevent leakage, a gasket s, of suitable material is interposed between the abutting edges of vthe neck portion o and neck member c. At

'the base of the recess p in baflle plate or plug 'y' are provided projections t which prevent adhesion of the weight z' to the bottom of the The valve mechanism of the bottle oper-` this vacuum, and, therefore, the adhesion of the valve to its seat, may be avoided by a contracted air passage u through which in the closed position of the valve the bottle neck above the valve seat communicates with the body of the bottle. Such air passage is, in the particular valve mechanism shown and described herein, preferably formed in the upper end of the valve 7L, because it has been found that in this position it is less liable to permit the passage of liquid downward through it than it might be in other positions, particularly as the weight z' in its closed position rests immediately on and partially closes it. By contracted air passage, as that phrase is here used, I mean a passage large enough to permit the passage of air from'one side of the valve or valve seat to the other, but small enough to prevent, on account of the air pressure inside the bottle, the passage of any substantial amount of liquid from the neck of the bottle into the body thereof.

What is claimed is '1. In a non-rellable bottle the combination of a valve and seat therefor interposed between the bottle body and neck, a weight resting upon andhaving a curved surface in contact with the upper end of said valve, and a contracted air passage through said valve in line with said weight and arranged to be closed thereby, said passage connecting tion of an inverted cup-shaped valve and seat therefor interposed between the bottle body and neck, a pear-shaped weight resting on the upper end of said valve, and a contracted air passage through said valve in line with said weightY and arranged to be closed thereby, said passage connecting the body and neck in the closed position of the valve.

4:. The combination, inthe neck of Va bottle, of a valve-seat having a central opening in line with the neck-opening, an inverted cup-shaped valve normally resting at Vits lower edge on said seat and closing the opening therein and adapted toA tilt upon and thenfmove bodily away from said seat when the bottle is tilted to pouring position, said valve having a contracted air passage, a weight normally resting upon the upper end of the valve and controlling its movements, said weight being in line with the ai'r passagev and having a curved surface in contact with the valve, and means above the weight for limiting the movements thereof, substantially as' described.

In testimony whereof, I have hereunto set my hand, inthe presence of two subscribing witnesses.

JACOB A. ULMAN.
