To all whom t may oon/cern,.- Y

Be it known that I, SAMUEL W. LUnLow, a

citizen of the United States, residing at Covington, county of Kenton, and State of Ken,- tucky, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speci- Io Jcation.

M y improvements consist of a certain novel construction and arrangement of parts, to be hereinafter particularly pointed out and claimed, for cheaply and effectively preventing the refilling of bottles, to which my invention is applied.

v The special object of my improvements is to provide a construction of a minimum numb'er of parts in which the valve is arranged to close even while the bottle is in a slightly-invverted position, to prevent lling by flowing the liquid into the bottle when in a horizontal position, and at the same time when the bottle is inverted to permit of theV ready withdrawal of the liquid by the constant admission of air as' the liquid is discharged.

In the drawings, Figure l is a central longitudinal section of the neck'of the bottle in upright position with my improvements in place. Fig. 2 is a similar section with the bottle. somewhat inverted, showing the valve closed. Fig. 3 isa similar view with the bottle inverted for the discharge of the liquid. Figs. 4: and 5 are `side and bottom plan views of the valve.

,A represents the bottle, and B its neck, at the lower inner end of which is molded the collar C, provided with a vertical iiange 0;, the upper edge of which is ground to forma suitable seat for the valve D. This valve is substantially a spherical segment with an upper rim b, which seats itself on the ground seat a to close the valve. The rim o has its periphery scalloped, leaving radial arms c o, which extend nearly to the innersurface of the bottle-neck to prevent the valve droppingfrom its seat. The lower surface of the valve D is formed with a suitable number of grooves or corrugations a3 d, whlch 1n connection wlth bottle and provided with a suitable numberv of passage-ways e e-say five or sixfor the discharge of the liquid andentrance of air,

each passage-way arranged'with a sharp angle to prevent the insertion of anywire or other device to unseat the valve. i

To hold the ba'ie-plug in position and prevent its withdrawal, annular grooves are rformed in the inner surface of the bottle-neck, and the plug and a spring-band f, bent on itself, is placed in the plug-groove, so that when the plug is pushed to place the upturned edge of the spring-band will catch in. the bottlegroove and prevent its withdrawal. The plug, however, can be secured by cement or in any other convenient way.

The inner surface of the baffle-plug h is cone-shaped, as shown, and a ball F is located in the space between vthe cone-surface of the plug andthe valve D. The location of the plug and the angle of the cone-surface is such that when the bottle is inverted to the extent shown in Fig. 2 the cone-surface will still forman angle above the horizontal' and cause the ball F to rest upon the valve and close it. In addition to this the center of gravity of the valve is considerably within the valveseat, and as the valve is spherical, even without the aid of the ball, the valve will close itself before the bottle reaches a position.

When the bottle is fully inverted, as shown in Fig. 3, the valve swings on one edge of the valve-seat, the liquid flowing out through the corrugations below, while the air enters through the upper corrugations.

All ofv the parts of the device can be made of glass and readily molded of the desired shape, the essential parts being merely the valve with the rim in the neck for aseat and the baiiie-plug. 4The ball is,- however, of assistance in causing a quick closing of the valve, and I therefore make use of same. The corrugations. around the valve and the passage-ways through the bafiie-plug are sufhorizontal ciently numerous to prevent the ball from forming a plug to stop the discharge of the liquid or admission of air.

An important feature is the narrow rimseat for the valve. This seat is amply sufcient to seal the bottle against refilling, and with such a seat there is no danger of the valve adhering to the seat when the bottle contents are to be discharged. All friction of the valve on its seat is thus overcome, and the Valve will open at once when the bottle is properly inverted.

It will be evident that the construction of parts is very simple and that the parts can be readily assembled.

When the bottle is iilled,the valve is dropped in place with the ball on top of the valve, the baHie-plug, with its retaining-band, is pushed to place, and an ordinary cork, if desired, can then be used to seal the mouth of the bottle. When the contents are Withdrawn it will be impossible to refill the bottle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a non-rellable bottle, the combination with a bottle-neck having an annular flange within its neck to form a narrow valve-seat, of a spherical segment-valve, grooved longitudinally with an annular rim to seat itself on the valve-seat, said rim extending to the surface of the neck and having scallops to coperate with the grooves of the valve to permit the discharge of the liquid and entrance of air, and a bafiie-pl ug to prevent access to the valve, substantially as shown and described.

2. In a non-rellable bottle, the combination with a bottle-neck having an annular ange within its neck to form anarrow Valve-seat, of a spherical segment-valve, grooved longitudinally with an annular rim to seat itself on the valve-seat, said rim extending to the surface of the neck and having scallops to coperate with the grooves of the valve to permit the discharge of the liquid and entrance of air, and a baffle-plug to prevent access to the valve, said plug having a conical recess and a ball-bearing on the valve within said recess to shut the valve when the bottle is slightly inverted, substantially as shown and described.

3. Inanon-refllable bottle, avalve for closing the same, comprising a disk-like scalloped rim for a seat, with an inwardly-projecting portion having longitudinal corrugations on its surface, cooperating with the scallops of the rim for the discharge of the liquid, and having its center of gravity substantially below the seat of the valve, whereby a prompt seating of the valve is obtained, substantially as described.
