NON REFlLLABLE BOTTLE.

$PIJGIFIGATION forming part of Letters Patent No. 726,519, dated April 28, 19034.

Application filed February 13, 1903. Serial No. 143,210. (No model.)

To all whom it may concern.-

Be it known that 1, Lotus C. EDWARDS, of Ellington, in the county of Tolland and State of Connecticut, have invented a new and use ful Improvement in Non-Refillable Bottles; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a vertical sectional view of a bottle constructed in accordance with my invention; Fig. 2, a side view of the combined stopper and fender detached; Fig. 3, a side view of the same viewed at right angles to the po-.

sition shown in Fig. 2.

This invention relates to an improvement in non-refillable bottles, and particularly to such as are formed with a contracted neckin which a weighted valve is arranged to be seated, with a stopper in the mouth of the bottle through which the contents of the bottle may be emptied, the object of the invention being a simple arrangement of parts whereby the possibility of tampering with the valve is avoided; and the invention consists in the construction as hereinafter described, and

particularly recited in the claims.

The lower end of the neck :2 where it joins the body of the bottle 3 is constricted to form a valve-seat 4. The neck of the bottle is also formed with an annular recess 5, semicircular in cross-section, and above this recess is The valve 7, which is formed from glass, has an enlarged lower end 8, adapted to enter the body of the bottle, and a cup-shaped end 9 of a diameter adapted to rest in the valve-seat, so as to close the neck of the bottle, the sides of the valve being of sufficient height to permit the valve to be turnedin the neck without producing an opening into the bottle. Preferably and as herein shown the upper portion of the valve is hollow, forming a cup 10. The stopper '11 closely fits the upper end of the neck and is formed with a vertical opening 12 and with a depending fender 13, the sides of which taper slightly and which is enough smaller than the diameter of the neck to permit the free flow of liquid around it. The lower end of the stopper above. the fender is cut away, forming a transverse opening 14, the upper edge 15 of the fender standing in a plane above the lower surface 16 of the annular recess 5. The stopper is held in position by a V-shaped spring 17, located in a vertical recess or slot 18 formed to receive it in one side of the stopper-11, the said spring being formed with a nose 19, adapted to enter the annular groove 6 when the stopper is pressed into the neck of the bottle. The opening 12 in the stopper may be closed by a cork.

It will be observed that owing to the location of the upper end of the fender above the lower edge of the semicircular groove 5 if a wire is passed through the stopper with the intention of dislocating the valve the end of the wire striking the upper surface of the fender will be deflected against the surface of the groove and naturally turned upward instead of downward into the neck of the bottle, so that tampering with the valve by means of a wire is practically impossible. 4

As before stated, the walls of the cupshaped valve are of such a height that the valve may be turned in its seat to a considerable extent without exposing the opening from the neck into the bottle, but will, however, readily slide forward when the bottle is inverted to permit the free discharge of the contents. The stopper and valve are so simple in construction that both may be readily formed from glass, and hence the only metal used is the spring, and this is so inclosed that it cannot possibly be aifected by or affect the contents of the bottle and is so secured that when the stopper is once in place it cannot be removed.

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

l. The herein-described non-refillable bottle consisting of a bottle having a valve-seat at the lower end of the neck, a valve resting on said seat, the neck also formed with an annular recess and an annular groove, a stopper inserted into the neck of the bottle, said stopper formed with a depending fender extending into the neck of the bottle and with a slot near its upper end, the upper surface of the fender being arranged in line above the lower edge of the said recess, and a spring arranged in the said slot in the stopper and adapted to enter the'groove in the neck, substantially as described.

2. The herein-described non-refillable bottle consisting of a bottle having a valve-seat at the lower end of the neck, a cup-shaped valve resting on said seat, the neck also formed with an annular recess and an annular groove, a stopper inserted into the neck of the bottle, said stopper formed with a depending fender extending into the neck of the bottle, the upper surface of the fender being arranged in line above the lower edge of the said recess, a Vertical recess formed 1n one side of said stopper, and a V-shaped spring located in said recess and formed with a nose- L. o.
