NON-REFILLAIBLE BOTTLE.

Specification of Letters Patent.

Patented May 5, 1914.

To all whom it may concern Be it known that I, MAX P. SCI-HILL, a citizen of the United States, residmg at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

The object of the present invention is to provide a cheap and simple non-refillable bottle of cheap construction while effective for the purpose desired.

In the accompanying drawing, Figure 1 is a vertical section of the upper portion of a bottle equipped with my invention; Fig. 2 is a similar view of the same in an inverted position; Figs. 3 and a are cross sectional views on the lines 3-43 and tl respectively of Fig. 1.

Referring to the drawing, 1 indicates the neck of a bottle to which my invention is applied. Within said neck is a casing 2 of a valve chamber, the lower portion 3 of which is cylindrical and formed at the bottom with an outwardly extending flange 4, spun around an apertured circular disk 6, said flange being contained within a groove .7 formed in the inner surface of the neck of the bottle, said casing being secured within said neck by a ring 8, of absorbent material, saturated with cement. Secured to the centor of said disk, and extending upwardly therefrom, is a stem 9, which stem enters a cylindrical socket formed in the center of a frusto-conical .valve 11, of cork or similar light material, the base of which valve, when resting upon said disk, completely closes the apertures 12 therein. Upon said valve rests a ball 13, of glass or similar non-corrosive material, the casing having a spherical top to fit snugly around said ball. In the wall of said casing apertures 14; are formed by cutting the metal of the casing along three sides of a rectangle and pressing the metal inward about the fourth or lowest side, as clearly shown in Fig. 1. The metal pieces forced inward thus serve as protectors, preventing the passage through said apertures 14, and access to the valve of wires or other instruments.

hen the bottle is inverted, the ball 13 rolls said valve, through the apertures 14, and out between the casing and the neckof the bottle.

A very important feature of my present invention resides in the fact that the valve 11 is made wholly of cork, and has no metallic parts attached thereto or movable therewith. Therefore it is very light, and consequently in pouring the liquid out of the bottle said valve vibrates very easily and rapidly. If this valve were of considerable specific gravity, as when it has attached thereto metallic parts, as in my U. S. Patent No. 1,019,585, then'the eifect would be that, in pouring liquid from the bottle, very considerable suction would have to be produced in the bottle before the valve would be drawn by said suction back to its seat. hen it would be so drawn to its seatit would not be dislodged therefrom by the weight of the liquid. With my improved valve this is not the case, for, because of its being lighter than the liquid being poured out it is drawn toward its seat by a very slight suction, while it is surrounded by the liquid being poured out, but, as soon as this liquid has left it, it is forced away from its seat by the liquid in the bottle, air passing by the valve into the bottle to reduce the suction in the bottle. Thus there is set up a very rapid vibration of the valve, the movement from its seat being caused by the movement of the liquid and the motion toward its seat by the suction produced by the discharge of said liquid. But, on account of the valve being very light, this vibration isproduced easily, by only a slight difference in pressure in the interior of the bottle, and consequently the suction in the interior of the bottle is never sutficient to permanently hold the valve to its seat. This would not be the case if the valve had metallic parts attached thereto, but the valve would remain oil its seat until a sufficient suction was produced to draw it to its seat and when once drawn it would be held tightly thereon. It is for this reason that I employ the stationary stem 9 by which the valve is guided in its vibration, instead of employing a metallic stem movable with the valve to guide it in its vibration.

My improvement also permits of great economy in construction. In my former device of Patent No. 1,019,535, in which I employed a valve having a metallic plate as a part thereof, the manufacture of said plate and the securing it to the buoyant part of the valve, was far too costly, and I can make a large number of my present valves at the same cost of a single one of the valves shown in my former patent. The present construction also permits of the valve seat having a large number of holes and therefore permits of a freer flow of the liquid. It will be seen the means for preventing refilling are very effective and at the same time cheap and easily made.

I claim 1. In combination with the neck of a bottle, an apertured casing secured therein, an apertured disk secured thereto, a stem secured to, and extending upwardly from, the disk, a valve made wholly of cork slidable on said stem within the casing and arranged in its seated position to close the apertures in the disk, and a ball Within the casing and resting on the valve when in its seated position.

2. In combination with the neck of a bottle, an apertured casing secured therein, an apertured disk secured thereto, a stem secured to, and extending upwardly from, the disk, a buoyant valve slidable on said stem within the casing and arranged, in its seated position, to close the apertures in the disk, and a ball within the casing and resting on the valve when in its seated position, said casing having integral protectors, each protector extending inwardly from that side of the aperture which is nearest the valve.

in testimony whereof I have hereunto set my hand in the presence of two subscrib ing witnesses.
