To all 'whom t may concern.'

Be it known that I, REN H. NRAT, a citizen of the United States,v residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be aV full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to bottles and jars, and the object of same is to produce a new valve and new coacting parts including a guard which, placed in and forming part of the neck of bottles and jars, renders them non-refillable. This object is carried out by constructing the bottle neck in a manner hereinafter more fully described and claimed and as shown in the drawings wherein Figure 1 is a central vertical sectional view through a bottle neck with the bottle inverted and in the act of pouring out its contents, and Fig. 2 is a similar view with the bottle upright, showing how the valve has dropped onto its seat to prevent the re filling of the bottle. Fig. 3 is an enlarged perspective detail of the valve, partly broken away. Figs. l and 5 are sectional views of slightly different forms of the valve; and Fig. G is an enlarged perspective detail of the seat, partly in section.

In the drawings I have used the letter N to designate the bottle neck, no matter whether the same be integral with the bottle body B or not, and I will refer to it by the term neck throughout the specification although it is quite possible that this tubular element within which is mounted my improved valve might be formed separate from the neck and attached integrally or otherwise thereto at a later time. If the bottle be of glass the neck will be of the same material, but if this tubular element be separate from the neck it may be of glass or any other material desired.

Coming now to the gist of the invention, the upper end of the neck is preferably closed as at 1 excepting for a central opening 2 somewhat smaller than the neck so as to produce a reduced mouth for the same, this mouth being intended to be closed by a cork or other commercial closure while the bottle is in storage or transit. Immediately beneath the mouth is a guard, herein shown as a disk 3 somewhat larger than the opening 2 and having a raised peripheral bead 1 which is'spaced longitudinally from the inner side of the upper end 1 as at 5 and is spaced radially from the interior of the neck as at 6, so that liquid flowing out of or in through the mouth must pass over the bead 4C and around the edge of the guard.

The neck N is illustrated as composed of two concentric tubular elements with an interposed spiral rib, and in manufacture Bil these may all be made integral or may be z made in separate parts and subsequently united in a waterproof manner. The outer element or shell 10 extends throughout the entire length of the neck and unites with the edge 0f the upper end piecel. The inner element or tube 11 is concentric with and spaced slightly from the shell than which it is 'somewhat smaller in both diameter and length so that its outer end stands some distance from the end plate l and its inner end 12 stands some distance from a shoulder 13 which projects inward from the shell 10 Vand coacts with another shoulder 14 to remunicating with the space 6 around the edge of the guard at the other' side of the neck. From the construction thus far described it will be clear that liquid passing either in or out, if it could not pass through the bore of the tube 11, would have to follow a spiral y course throughout the length of the channel 16 and flow about once around the neck in its passage.

Clamped between or in any way mounted in the space between the shoulders 13 and 14 is a valve seat best shown in detail in Fig. 6. The same comprises a tubular body 2() in the shape of a truncated cone, and an outstanding flange 21 projecting from the larger lower end of the body into the space between said shoulders, wherein it is shown in Fig. 2 as being held between suitable rings of packing 22. The smaller upper end 423 of the body is of somewhat less circumference than the interior of the tube 11.

The valve best seen in Fig. 3 comprises a cylindrical body or shell 30 open at its upper end 33 and closed at its lower end, and by preference I would make this valve of very thin metal and quite light, the circumference of its body being such that it willfit closely and yet slidably within the bore of the tube 11. At the lower end of the body the metal of which'it is composed is bent abruptly inward in an acute angle 34, then carried obliquely upward in an inclined wall formed in the shape of a truncated cone 35 whose smaller upper ond is closed as at 36. In the form of the valve shown in Figs. l, 2 and 3, this closure is an annular band, and from its inner edge depends a short section of cylinder 37 extending downward to a point 3S about opposite the vertex of the angle 34, beneath which it is closed by a` cone-shaped bottom 39. In Fig. 4 the structure of the valve is t-he same excepting that the cone-shaped bottom 39 is replaced by a flat bottom 40. In Fig. 5 the short section 37 of cylinder is omitted, and the upper end of the truncated cone 35 is closed by' a flat plate 41. But I consider it important to state that in any case the inclination or pitch of the wall of the cone 35 on its interior is less than that of the exterior of the body 20 of the seat. Attention is here directed to the fact that the seat 20 is of such size and so disposed that its body 20 crosses the path of the shell 30 of the valve, and the result is that when the valve closes upon the seat as seen in Fig. 2, the vertex of its angle 34 strikes the outer face of the body 2O at a point between the upper and lower edges of the latter and close engagement results.

The guard is mounted upon the upper end of the tube 11 in any suitable manner which will permit liquid within the space 6 to fiow into the upper end of said tube, for a purpose yet to appear; and by preference I provide the disk 3 with tongues or fingers 43 around its edge which are secured within the upper end of the tube 11 at intervals and in any suitable manner, leaving spaces 4.6 between them which communicate with the space 6 and making use of their inner eX- tremities as stops to limit the outward movement of the valve. It will be observed from Fig. 2 that when the valve is closed the upper end 33 of its body is spaced from said stops and the vertex of its angle 34 rests on the seat; whereas when the valve is open as seen in Fig. 1 the vertex of its angle is olf the seat and its upper end rests on said iingers, its length being such that at this time the spaces 17 and 18 are thrown into communication over the upper end 23 of the seat.

In use, the bottle is filled and probably the neck N will afterward be applied and sealed in place, the mouth 2 is corked or otherwise closed, and the bottle shipped to the consumer. To pour off its liquid, the

cork is removed and the bottle inverted as seen in Fig. 1. The valve now falls away from its seat against the fingers 43 and the spaces 1S and 17 are thrown into communication as just stated, and liquid flowing over the seat at 23 enters the spiral channel 16 and passes around the convolutions thereof to the point 1S), whence it flows alongside the guard as at 6, between it and the top plate 1 as at 5, and out the rnouth 2. This is the action whether the bottle is completely inverted as shown, or only partially. After using, the bottle is restored to the position shown in Fig. 2, and the valve drops closed onto its seats ready to act again when more liquid is to be poured out.

IVhen now it is attempted to refill the bottle, the advantages of the construction described appear. Vihatever the position in which the bottle is held, when liquid is poured orvforced into its mouth 2, some of it passes through the spaces 46 between the fingers and gets into the cup-shaped body 30 of the valve. If the device stands upright as seen in Fig. 2 the valve will obviously drop to a closed position by its own weight and the' added weight of the liquid therein, and this also is true if the bottle stands inclined. If the bottle should be first inverted and the valve allowed to fall to its open position as seen in Fig. 1, and it is then turned on its side to a horizontal position, it will yet be impossible to refill it, as I will show. Liquid forced into the mouth 2 now'strikes the guard and passes around its lower edge to the point 19 where it enters the first convolution of the channel 16 and rises inside the same as the supply is kept up; but in so doing, some of the liquid passes through the space 46 under and behind the guard and into the cup-shaped body 30 of the valve,- and rises simultaneously therein.

Manifestly it will be impossible to force liquid. into the channel without also forcing it into the Valve, and before sufficient liquid has been driven into the channel to cause it to travel around even the first convolution thereof, the weight of the liquid within the valve will slide the latter within the bore of the tube 11 and close it upon its seat. Thereafter, even if it were possible to force the liquid around the several convolutions of the channel, when it came to the point 17 where the innermost convolution opens outside the seat, it would strike the valve (which now rests tightly on the seat) and could not enter the bottle. The guard therefore serves the purpose of causing some of the liquid to be admitted to the valve so as to seat the latter, V

even though the bottle neck stands horizontal; and in addition the guard serves its customary purpose of preventing the insertion of an instrument to hold the valve open While the bottle is refilled. The conical bottom 39 in the valve shown in Fig. 3 amplifies 'of the idea disclosed in a prior application by me bearing Serial Number 857,7 27, filed August 20th, 1914, allowed June 7, 1915, and abandoned January 3, 1916.
