NON-REFILLABLE BOTTLE.

Specification of Let ers Patent.

racemes Jul is, 19118.

Application filed March 28. 1917., Serial No. 156,026.

To ail whom it may concern:

Be it known that I, RAY E. Bean's, a citizen of the United States, residing at Syracase, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specifi: cation.

This invention relates to improvements in non-refillable bottles, and has for its object togenerally improve and simplify the construction and operation of devices of this class.

The various features and parts of the invention will be understood from the detailed description which follows and by reference to the accompanying drawing, in which Figure l is a central vertical section showing my improvement applied thereto, in which the valve is in the position for preventing refilling of the bottle.

Fig. 2 is a similar sectional view in which the valve is released for allowing the contents of the bottle to be drawn out.

Figs. 3 and 4: are respectively a top plan view and a side elevation of the threaded stopper.

Figs. 5 and 6 are respectively top plan view and side elevation of the valve shown in Figs. 1 and 2. i

In the drawing, 2 represents the body of a bottle or like liquid container, and 3 is the neck having a bore 4. 5.represents an infernal thread-ed portion intermediate the ends of the neck, and 6 represents a reduced opening or'port arranged in a flange 7 at the base of the neck. In the preferred form, the bore of the neck between the threaded portion 5 and the flange 7 is tapered, as shown in Figs. 1 and 2. In filling as well as emptying the bottle 2 the liquid must pass through the port 6, and at the time of the filling the neck is preferably free and clear of any obstructions. After the liquid is -forced into, or otherwise applied to the bottle :2, a valve X preferably tapered, corresponding to the shape of the lower portion of the neck, is placed in position upon the fiange 7, as shown in Fig. 1, in which posi tion the valve completely closes the port 6. The next step consists of screwing into the thrcadel portion 4 a threaded stopper which has an opening 9 through its vendor in line with the port (3. in order to apply the stopper S, the top surface thereof is provided with radial angular notches-l0 to rcceive a screw driver or like instrument. The notches 10 in the drawing are formed with one straight vertical edge or shoulder 10. The opposite sides of the said notches-comprise inclined surfaces l() (in the drawing, the notches 10 are arranged for right hand screw threads). By this construction and arrangement, the stopper may only be driven into the threaded portion of the neck by the right hand turning of a screw driver, and the purpose of the peculiar notches 10 is to prevent the stopper 8 from being unscrewedor removed after it is once driven tightly into the threaded portion of the neck. After the stopper is ap lied as described, a common cork 11 may e forced into the clear top portion of the neck, as shown by dotted lines in Fig. 1. To draw 01? the liquid, the cork 11 is first removed, the bottle should then be tilted as shown, in Fig. 2. The liquid flowing through the port 6 then forces the valve X away from the seat 7 toward and against the bottom side of the stopper 8, and as the bore of the neck increases in diameter towardthe stopper, a

considerable space is provided around the valve to allow the liquid to flow uninterruptedly. The top of the valve X is preferably fiat corresponding to the bottom of the stopper 8 and to allow the liquid to reach the port 9 ofthe stopper, I provide a number of V-shaped radial grooves or notches 12, as best seen in Figs. 1. 2 and The flow of the liquid around the valve and through the grooves is free enough to permit of the ready drawing on of the entire contents of the bottle. If an attempt is made to refill the bottle, the glass or other stopper 8 being irremovable unless it is broken and removed in )ieces, affords the first hindrance to the re lling. The valve X being confined between the stopper 8 and the ledge 7 will be driven or forced by the liquid flowing throu h the port 9, inwardly against the seat 7, w iere it completely closes the port (3, and as there is no means for unseating the valve X while the pressure of the infiowing liquid is against the valve, the refilling operation cannot be successfully accomplished.

The means for rendering bottles non-relillable herein shown and described is extremely simple. The feature of the screw stopper 8 which may be screwed into the neck, but cannot be unscrewed. has advantages which are believed to be novel. The

. screw threads, the portion of the neck be- 7 I valves X are also novel and durable and provide adequate security against the refilling of the bottles after the original liquids are once drawn off.

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

In a non-refillable-bottle, the combination of a hollow neck separated interiorly from the body of the bottle by an annular flan e forming a central port, the interior of t e neck provided intermediate its ends with tween. said threads and the free end th'ereof being cylindrical and adapted to receive a cork, the interior of e neck below said threads gradually tape ng and contracting tosaid flange, a threaded stopper having a central liquid port irremovably disposed in the threaded portion of the neck; and a gravitative float-valve disposed in the contracted interior adapted'to control the flow of the liquid through the port in said flange.

In testimony whereof I aflix my signature.

RAY E. BURNS.
