NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 609,716, dated August 23, 1898.

Application filed March 19, 1897- To all whom it may concern:

Be it known that I, SIMON S. WHITAKER, a citizen of the United States, residing at Venetia, in the county of -Washington and State of Pennsylvania, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to improvements in antirefilling bottles; and it consists of certain novel constructions, which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings,formin g part of this specification, Figure 1 represents a central vertical section through a bottle embodying my invention. Fig. 2 represents an enlarged detail top plan view of the stopper or guard. Fig. 3 represents an enlarged detail perspective view of the expansion-ring, and Fig. 4 represents an enlarged detail perspective view of the valve.

1 in the drawings represents the bottle proper; 2, the valve; 3, the guard or stopper, and 4 the expansion-ring. The bottle 1 is of any desired construction and material with the exception that it is formed in its neck with a conical valve-seat 5, upon which the hollow conical valve 2 is adapted to be seated. This valve is provided with a plurality of outletapertures 6, adapted to be closed when the valve is in its normal lower position by an elastic packing-ring 7, applied on the conical seat 5. The said valve 2 is protected from above by the guard or stopper 3. This guard comprises a body portion 8, formed with an annular peripheral groove 9, and a plurality of vertical passages 10, arranged concentrically about its center. The lower portion of said stopper is formed with an annular downwardly, inwardly, and upwardly extending flange 11, the edge of which terminates some distance below the body portion 8 and within the circle formed by the vertical passages 10. The lower portion of the flange 11 is adapted to be seated upon an annular shoulder 12, formed upon the inner surface of the neck of the bottle. The stopper is secured in position in the neck of the bottle by a split me- Serial No. 628,255. (NoinodeL) .tallic expansion-ring 4, which lies partly within the annular groove 9 of said stopper and partly within an annular groove 14, formed in the neck of the bottle.

It will be observed from the foregoing description that the valve 2 is free to move vertically away from or toward the valve-seat 5, but is guarded from all interference from above by the stopper or guard 3. By the pe culiar construction of the flange 11 the insertion of any instrument through the vertical passages 10 is prevented and the valve 2 thus fully protected against any external interference.

In applying the several parts of my invention in position the conical valve 2 is first seated and the stopper 3 then forced down into the neck of the bottle until the expan sion-ring 4 snaps out into the groove 14. The stopper is now permanently locked within the bottle and cannot be withdrawn.

When the bottle is inverted to remove its contents, the conical valve leaves its seat, and thus uncovers the apertures 6 and permits the liquid to flow outward. Should any at tempt be made to refill the bottle, the force of the liquid, as well as the gravity of the valve 2, will immediately set the latter, and thus cover the aperture 6 and prevent any ingress of liquid. By thismeans the bottle is protected against any refilling with an infe rior article.

The valve and stopper of my improved device are preferably constructed of glass, so that the contents of the bottle will not be con taminated in any manner by contact therewith.

The construction and operation of my improved device is very cheap and simple, but at the same time very efiective, as the bottle when once emptied cannot again be refilled without so destroying the several parts mount ed in its neck as to render the bottle useless.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In an antirefilling bottle, the combination with the bottle proper having a conical valveseat and an annular shoulder formed in its neck, of a conical flexible washer mounted on said valve-seat, a hollow conical valve mounted on said washer and formed with a plurality of apertures adapted to be closed when the valve is seated, and a guard mounted in the neck above the valve so as to rest upon the annular shoulder and formed with a plurality of concentric Vertical passages and an inwardly and an upwardly extending flange adapted to protect the lower ends of said passages; the inwardlyturned flange of said guard also acting as a stop to limit the move IO ment of the Valve, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

SIMON S. WHITAKER. Vitne'sses:

WM. WYKE.
