Claims.

I This invention relates to non-rellable bottles, land has for one of its objects to provide an yeconomical vconstruction which is simple and Yeffective to enable the uid in the bottle to flow freely therefrom when the bottle is tilted, and yet 'l ofsuch'nature as to prevent the bottle from being refilled by pouring liquid inwardly through one of Vthe vents of the structure. Y

Another vobject of the invention is to construct `abottle which, through the use of a valve, prevents the bottle'from being relled with spurious VVcontents once the original contents have been emptied therefrom. l

The construction ofthe bottle is such that there are separate-vents or channels for the flow of liquid and the flow Aof air, which vents are nor- 4 mally closed by a valve when the bottle is righted toprevent evaporation. This valve is adapted to -be unseated by the downward Viiow of the liquid when the bottle is tilted, and to be reseated by -fgi'avity and/ or a spring when the bottle is righted.

A feature of the invention, though not a neces- *saryjconstructiom is a passage through the valve communicating with both vents when the valve -is -seated, to insure that spurious liquid forced through one vent will be returned through the -otherlvent without any of the spurious liquid entering the 'interior of the bottle below the valve. Another feature which may be used, if desired, kvis a spring between the top of the valve and the chamber for insuring closure of the valve when the-bottle lis empty and in a tilted position, to

prevent Arelling in the inverted position.

`V The following is a detailed description of the invention,

wherein: 1

' Fig. l illustrates a top or plan view of the neck in conjunction with a drawing,

ioffa'bottle embodying the invention;

2` illustrates a vertical sectional View V-through the neck of the bottle of the invention, showing'the valve seated;

Fig. Billustrates theA same sectional view of fFigfZ' showing theunseated position of the valve whenfthe bottle is in inverted or tilted position. In iorder to more easily compare both of these portion provided on its outer surface with a helical thread I'I and on its inner surface with a pair of Vspaced inwardly projecting annular ribs 2, 2. A sleeve or shell 3 of a suitable material, such as cork, is snugly fitted within the neck of the bottle. This sleeve or shell is tightly wedged between the bottle neck I and an interior stopper 4, of porcelain or other desired material. 'Ihe stopper 4 is provided with a projecting annular rib 5, such that this rib and the ribs 2, 2 of the neck of the bottle press tightly into the cork sleeve 3, as shown, to produce a firm tight seal between the cork sleeve and the adjacent elements. By this arrangement, the stopper will be securely held in place and prevented from being removed in order to rell the bottle.

In order that liquid may flow from the bottle through the stopper, there has been provided a liquid vent 6 and a smaller air vent 'I which extend from the upper end of the stopper to av chamber 8 in the interior of the stopper. Chamber 8 is designed to accommodate a cylindrical valve 9 inthe form of a piston, and is provided at its lower end with a reduced mouth produced by a circular flange I4 to restrict the movement of the valve. Valve 9 has, at its lower end, an off-center stem or pin I2, and at its upper portion a pair of oppositely disposed keys I0, I0 which slide in correspondingly located keyways Il, II to prevent the valve from turning in the chamber 8. At substantially the center of the upper part of the valve there is located a transverse hole I3 which communicates with both vents 6 and 'I when the valve is seated, i. e., in its lowermost position. A tinned small metal spring I8 is located between the top of the valve 9 and the upper wall of the cylinder 8, as shown. This spring I8 is of such construction that the valve 9, under pressure of only l dram of liquid, will compress same when the bottle is tilted.

In order to provide an air bubble in the bottle at a point below the mouth of the chamber 8, the stopper 4 has a portion I5 which extends below the flange I4, and which is provided with an air passageway I6 located on the same side of the chamber 8 as the airvent 1. Passageway I6 communicates with chamber 8 and, together with air vent 1, enables a free flow of air from the outside of the bottle to the lower interior thereof when the bottle is tilted to raise or unseat the valve to the position shown in Fig. 3.

Flow of liquid is controlled by means of the valve 9 which in its lower position (note Fig. 2) tightly seals the mouth of chamber 8 from' the vents 6 and l. 'I'his seal, together with the close tightening the seal 'between the valve 9 and theVV flange hl, the t between the valve 9 and the wall of the chamber 8 being suiiiciently close to prevent any real iiow between these parts. The Valve 9 will be seated in the position shown in Fig. 2 by gravity, whenever the bottle is righted.

`When the bottle is tilted, the pressure of the liquid contents on the bottom of the valve S'will cause the valve to slide toward the upper end of chamber 9 and to assume the position shown in Fig. 3. In this position, the spring I8 will be depressed, this spring being of such construction that an extremely small amount of liquid in the bottle will be suilicient to-move the valve to the location shown in this figure. The liquid contents are thus free to flow through chamber 8 and out of vent 6, but will be prevented from entering either air vent 'I or air passageway I6 by the stem l2, which due to its construction effectively separates the lower part of chamber into two chambers. In the unseated position of valve 9, air will iiow freely into the bottle through vent l, the right hand chamber produced by stem i2, and air passageway I6.

What is claimed is: f

l. In a non-rellable bottle, a stopper adapted to be tted into a bottle neck, a sleeve tightly wedged between said stopper and said neck, a chamber in the interior of, said stopper and communicating at its lower end with the interior of said bottle, the opening of said chamberinto the interior of said bottle being smaller than the widest portion of said chamber, a liquid passage and an air passage leading upwardly from and on substantially opposite sides of said chamber, another air passage leading downwardly from and substantially on the same side of said chamber as said iirst air passage, a valve slidable in said chamber from a lowered position in closing relation to said opening to a raised position, said valve having at its lower end a stem which when said valve is in raised position divides said chamber into two chambers, one of which enables the flow of liquid from the interior of said bottle into said liquid passage, and the other of which provides a path of travel for the air flowing from said upwardly leading air passage to the other air passage. l

2.
