NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed .T une 21, 1916. Serial N o. 105,031.

To all whom t may concern.'

Be it known that I, SOLOMON NARUNSKY, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to non-reflllable bottles having a valve which is so constructed and arranged that while it permits the free flow of the liquid from the bottle, it seats if an attempt is made to force any liquid back into the bottle, thereby preventing unscrupulous dealers from refilling of the bottle after it has been emptied.

The invention has for its object to provide a simple, inexpensive and highly eiiicient valve mechanism of the kind stated, and one which can be easily applied to the bottle.

With the object stated in view, the invention consists in a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing, Figure 1 is a vertical section of the valve mechanism positioned within the bottle neck, and Figs. 2 to 5 are respectively perspective views of the valveguard, valve-weight and guide, valve, and detachable valve-seat detached.

Referring specifically to the drawing, 9 denotes the neck of an ordinary glass bottle formed with an internal annular shoulder 10 which serves as a seat for the valve mechanism, and some distance above this shoulder is an internal annular groove 11 designed to receive a retaining device for the valve mechanism.

The valve mechanism comprises the following parts:

In the neck 9 of the bottle is mounted a cylindrical pouring tube 12 having its lower end threaded to receive a detachable plug 13 provided with a Huid passageway 14 opening at one end into the bottle and at the other end into the tube 12. |The end of the plug 13 which extends into the tube 12 forms a seat for a valve 15, said seat having an annular raised portion 16 over which the valve seats, the latter having a bottom recess in which the raised portion fits when the valve is seated, and in this position of the valve it closes the upper end of the passageway 14 opening into the tube. The part 16 centers the valve on its seat. On the side of the valve body are longitudinal ribs 17 which space the same from the inner surface of the tube 12 so that the liquid may flow past the valve when it is unseated and the bottle is inverted. From the back or top of the valve rises an integral stem 18 on which is slidably mounted a sleeve-like member 19 having outstanding longitudinal ribs 2O on its outer surface. The base of this member is enlarged, and Seats on the top of the valve 15 when the latter is seated. The opening 22 of the member 19 tapers upward, as shown in Fig. 1, and it is rabbeted at its lower end to seat on a shoulder 23 on the top of the valve. The length of the stem 18 is such that it projects above the member '19 when the latter and the valve are seated. The diameter of the member 19 is such that the liquid can flow past the same.

Above the valve stem 18, the tube 12 incloses a valve guard 24 having at the bottom a central cavity 25 to seat on the upper end of the valve stem, and a top central cavity 26. The guard has ribs 27 on its side which project a short distance from the ends thereo Above the guard 24, the tube 12 is contracted as shown at 28 so that its inside diameter is here less than the diameter of the guard, whereby the latter is prevented from slipping out of the tube. The contracted end of the tube forms an external shoulder thereon on which seats an encir cling retaining ring 29 which extends into the groove 11, with a washer 30 interposed between the shoulder and the ring, the latter thus serving to hold the tube 12 in the bottle-neck 9. The lower end of the tube is held by the plug 13 which seats on the internal shoulder 10 of the bottle neck 9. Between the plug and the lower end of the tube is located a washer 31.

When the bottle is in upright position, the valve 15 closes the same by seating over the upper end of the passageway 14, and it is held closed by the member 19 seating on the valve, and the member 24 seating on the valve stem, as sho-wn in Fig. 1. Wfhen the liquid is to be poured from the bottle, the latter is tilted as usual, whereupon the valve Patented May 29, 191V?.

15 and the parts carried thereby slide up- 11G ward in the tube 12, opening the passageway 111 into the tube. The tilting of the bottle causes the guard 24: to drop sidewise in the neck and its weight upon the tip end of the valve stem has a tendency of slightly tilting said valve from its seat to overcome any adhesive condition due to the stickiness of the fluid. rlhe liquid can now enter the tube, and it flows past the valve and the members 19 and 2li, and is discharged from the tube through the contracted end 9.8 thereof. Upon placing the bottle again in upright position, the valve is at once rescated, and the parts 19 and 211 follow the same and again assume the position shown in Fig. 1. rllhe top pro` jecting ends of the ribs 27 space the member 211 from the contracted outlet end of the tube when the valve is open, and thus serve to prevent said member from obstructing the free flow of the liquid from the tube. rl'Che member 19 gives the valve sufficient weight to cause a quick closing movement, and it also serves to guide the valve to its seat. The guard member 211 effectually prevents the insertion of a wire or other device for holding the valve off its seat, thus frustrating any attempt to refill the bottle. An attempt to force liquid into the bottle while it is tilted and the valve is off its seat will cause the same to be seated at once as the member 24 would press against the valve stem 18 and thus force the valve Copies of this patent may be obtained for to its seat. The member 19 would also do this if any liquid should happen to get past the member 211.

The valve mechanism may be made of glass, its parts are few and simple, and they can be easily assembled, this being done 'before the plug 13 is applied and the tube 12 is positioned in the bottle neck 9.

.l claim:

rlhe combination with the neck of a bottlc, of a pouring tube having open ends and a contracted upper end forming an external shoulder, a valve-seat plug having a central aperture detachably connected to the lower end of said tube, a valve in the tube adapted te engage said valve-seat and provided with a rigid upwardly extending stem, a weight on said valve encircling said stem, a valve-guard loosely seated on the top of the end of said stem below said contracted end of the tube and provided with vertical ribs on its outer side and which project above the body-portion of said guard, and a clamping means engaging said external shoulder on the tube and the interior of the bottle neck for locking the tube in position.

In testimony whereof l a'tX my signature in the presence of two witnesses.
