BOTTLE.

SPECIFICATION forming part of Letters Patent No. 601,848, dated April 5, 1898. Application filed October 2 2, 1897,; Serial No. 656,010. (No model.)

1'0 M6 whom it may concern: Be it known that I, WILLIAM WILSON, a citizen of the United States, residing in Oakland, county of Alameda, State of California, have invented an Improvement in Bottles; and I hereby declare the following to be a full, clear, and exact description of the same.

. My invention relates to improvements in 7 bottles, and is especially designed to prevent introduction of liquid through it, and a means for closing the air-inlet passage for a similar purpose.

It also consists in details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a sectional elevation of my device as applied to a bottle. Fig. 2 is a view showing a different arrangement of its parts. Fig. 3 is an outside View of the same.

The object of my invention is to provide a cheap and effective means for preventing the fraudulent refilling of bottles after the contents have been discharged and at the same time provide a convenient means for the discharge of the contents of the bottle.

A is a bottle having the usual neck or opening for the introduction and discharge of its contents.

When the bottle has been filled, Iaffix upon its neck a tubular extension B, which is here suitable ductile material, can be compressed into the grooves or around the neck, so as to be permanently locked thereto. In the outer end of the extension is a cork or stopper 0 charge-opening.

of any suitable description, which is connected with a screw-threaded movable stem or sleeve 0'. stem enters the end of the section, and turning in screw-threads interior thereto it is moved outward or inward by simply rotating it upon its own axis. The stopper orcork is fitted to the inner end of this stem and when turned inwardly fits into or against the neck of the bottle, so that it will hermetically close it.

In the form shown in Fig. 2 I have illustrated an external sleeve fitting over the cylindrical extension having a spiral slot made in it, and this slot, fitting over a pin which projects from the side of the extension, is caused to move outward or inward whenever it is turned around upon an extension. In this case the cork or stopper is carried upon the interior of the moving sleeve, and when the sleeve is turned in one direction the cork is fitted into or against the neck, so as to close it, and when turned in the other direction it is withdrawn to allow an open passage.

In order to discharge the liquid after the cork or stopper has been withdrawn, I have shown a passage E, provided with an outwardly-opening flexible valve F. This valve may be made of rubber or any suitable or desired material, so constructed that it will open outwardly by the pressure of the liquid upon it, but will close hermetically against the opening to prevent any liquid being introduced. The casing G, Fig. 3, in which this valve F is contained, is here shown as havinga glazed outer end G, through which the valve can be constantly observed and any tampering with the valve will be detected at once.

In order to allow air to enter the bottle as fast as the liquid flows out, I have shown an opening H upon the side opposite to the dis- With this opening is a casing 1, within which is a piece of tissue-paper,

silk, or other similar light material which presents no obstacle to the passage of air around it by reason of its lying up loosely from the opening which it covers. The casing in which this valve or material is contained has small perforations made in the outer cover or end of it, so that the air can freely enter, and when the apparatus is in its normal condition it is only necessary to withdraw the stopper,

In Fig. 1 this screw-threaded neck when it is inverted.

struction is avery steady and even flow without the gurgling and interruption caused by the entrance of air into the ordinary bottle- If an attempt be made to introduce water through the air-Valve portion, the moment the silk or tissue-paper becomes wet it will lie down fiat, stick, and

cover the inlet-opening and absolutely prev; Vent any liquid passing through in that direction.

It will be understood from the drawings that the position of the outlet-opening may be changed and that it is not necessarily in line with the air-inlet opening. Fig. 2 shows it at the end of the extension instead of upon one side.

With bottles of this description, the eontents having once been emptied they cannot be again filled without removing the extension. This extension may be so made that with the proper tools, such as would be e1nployed in the shop where it is manufactured,

it could be removed from the bottle-neck, so that the latter could be refilled and the cri mping or securing tools could be again used to fix the extension in place.

Having thus described my lIIVGDtiOILWVhfl/D 1 having a stopper fixed to its inner end, means for rotating the carrier to withdraw the stopper or close it against the neck of the bottle, a chamber in the upper part of the extension, an opening made in theextension communicating with the chamber, said chamber having a discharge-passage at one side through which liquid may flow when the bottle is tilted for the purpose, and an automatically-acting inwardly-closing valve between the chamher and interior of the extension whereby liquidis prevented from entering the bottle from I-he discharge-passage.

2. The combination of a bottle with an extension fixed to and essentially in line with the neck, a spirallygrooved carrier fitting and movable with relation to the extension, havi-nga stopper'upon its inner end by which the neck is opened or closed, a chamber in the upper part of the extension and communicatin g therewith through a discharge-passage opening from the extension, an automatic in wardly-closing valve or diaphragm control- .ling said opening whereby liquid is prevented from entering through the discharge-passage, a second passage for the inlet of air to replace the discharged liquid, said passage having a valve or diaphragm fixed within it which will allow the ingress of air to replace the discharged liquid but it will arrest the passage inwardly of any liquid.

In witness whereof I have hereunto set my hand.

WILLIAM WILSON. Witnesses:
