BOTTLE-CLOSUR-E.

Loenen.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed February 19, 1910. Serial No. 544,786.

To all whom it may concern:

Be it known that I, JOHN P. Bnnssnn, a citizen of the United States, residing at Hamilton, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Bottle- Closures, of which the following is a specification.

This invention relates to improvements in bottle closures and has for its object to provide an improved device to be secured in the neck of the bottle. which will permit the ready escape of liquid therefrom but which will so eifectually prevent the flow of liquid into the bottle as to render the latter operation commercially impracticable.

With the above object in view the inven tion is illustrated in the accompanying drawing, wherein,-

Figure 1 is a vertical sectional view through the outer end of a bottle neck and the improved closure device therein. Fig. 2, is a similar view through the detached closure. Fig. 3, is a side elevation of the detached closure. Fig. 4, is a horizontal sectional view of the sama-the section being taken on the line 4`4 of Fig. 3. Fig. 5, is a cross-sectional view of the same taken on the line 5 5 of Fig. 3, and Fig. 6, another cross-section taken on the line 6-6 of Fig. 3.

Referring to the drawing by numerals, 1, designates the body of a bottle and, 2, the

' neck thereof, both of which may vary somewhat in design from that shown.

The closure may be formed of any suitable material such as porcelain, glass or other substance that will not be affected by contact with the liquid in the bottle and which will not taint or injuriously alter the liquid passing therethrough.

In the present instance the closure, 3, is shown as comprising two halves merely for convenience in manufacture but this is not essential and the invention is not to be so restricted. The closure has the form of a stopper in that it has a body that extends longitudinally in the neck, 2, of the bottle and is provided at its upper end with a central longitudinal chamber, 4, and a plurality of ports or passages, 5, that extend laterally from the lower end of said chamber to the outer circumference of the stopper. Between the ports or passages, 5, and the upper edge, 6, the stopper is provided with a circumferential groove, presently to be described.

The lower end of the closure or stopper is provided with a central vertical passage, 8, the upper end of which opens into or communicates with a central valve chamber, 9, that has position in a horizontal plane between the chamber, 4, and said vertical passage, 8. The lower end of this chamber and at the point where it is entered by the central passage, 8, is provided with a valve seat, 10, that is formed by beveling the surrounding wall so that a valve, 11, may be placed in said chamber and have vertical movement therein to cover the upper end of the vertical passage by dropping or rolling against the seat. By preference the valve, 11, is spherical in form so that it may readily roll toward or away from the seat, 10, upon inclining the bottle. A plurality of ports or passages, 12, are provided in the side of the closure or stopper, which extend laterally from the valve chamber, 9, above the said seat, and said passages also open at the outer circumferential side of the closure or stopper.

By reference to Fig. 3 of the drawing it will be noted that the ports or passages, 5, at the upper portion of the stopper have position in a vertical plane about midway between two adjacent ports or passages, 12, of the valve chamber and that said upper and lower ports are brought into communication with each other by means of a Zigzag circumferential groove, 13. This groove is formed in the circumference of the closure or stopper and extends up and down while advancing around the wall of the stopper and at each upper turn the groove communicates with one of the ports or passages, 5, that lead to the central chamber, v4, while at each lower turn the said groove communicates with one of the ports or passages, 12, that open into the valve chamber, 9. B reference to Fig. 3, it will be seen that the lower turns, 14, of the groove, 13, extend slightly below the ports or passages, 12, and this is a desirable feature because if a wire or other instrument is fed down through one of the ports, 5, and groove, 13, the end thereof will pass below the port, 12, near the lower end of the groove and will thus be prevented from turning into the said port, 12, where it might possibly pass beneath the 7, for a purpose valve, 11, while the latter is unseated and thus hold the latter away from its seats.

An annular groove, 15, is provided on the circumference of the stopper or closure between the lower end, 16, thereof and the lower turns, 14, of the groove, 13, so that when the stopper is forced down into the bottle neck, cement, 17, may be placed in said groove, 15, and also in the groove, 7,

vnear the upper end so as to secure the stopper to the wall of the bottle neck. An ordinary cork stopper, 18, may be inserted in the central chamber, t, at the dischargeend of the device to effect a closure of said end.

Having thus described my invention what I claim and desire to secure by Letters Patent is The combination with a bottle neck, of a closure therein and having a central stopper chamber at the upper end and a valve chamber having an outlet at the lower end and the closure having an endless circumferential zig-Zag groove extending up and down between the upper stopper chamber and the lower valve chamber and each npper turn of said endless groove communicating with the stopper chamber While each lower turn of said endless groove communicates with the valve chamber whereby to provide liquid outlet and air inlet passages and a valve in said valve chamber.

In testimony whereof l aiiiX my signature in presence of two witnesses.
