NON-REFILLABLE BOTTLE.

SPECIFICATION forming wart of Letters Patent No. 783,120, dated February 21, 1905.

Application filed May 18, 1904. Serial No. 208,629.

To all whom it may concern.-

Be it known that we, ALEXANDER GEORGE LEDERER and HARRY BENNETT DE FORD, citi- Zens of the United States. residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in N on-Refillable Bottles,of which the following is a specification.

Our invention relates to non-refillable bottles;'and it is our object to provide a bottle that is proof against fraudulent refilling when once emptied of its original contents.

In the accompanying drawings, Figure 1 is,

a front elevation, partly in section, showing the neck of our bottle with stopper inserted. Fig. 2 is a top plan view of the same with stopper removed. Fig. 3 is a vertical section taken on the line :1: of Fig. 2. Fig. 4 is a bottom plan view of the stopper. Fig. 5 is a section taken on the line 3 y of Fig. 4. Fig. 6 is a side view, partly in section, showing the neck of the bottle tilted, the mouth, and the position of the valve in its cage or shell when open. Fig. 7 is a modification of the guardstopper.

Referring more particularly to the drawings, A designates the neck of the bottle, formed with an annular shoulder a and an L- shaped groove (0' upon its interior wall, the

' horizontal portion of which runs quarter-way 4 denotes an offset or l1pin the neck, forming a mouth (0 B denotes the stopper, having the knob b on top and a rectangular stud 7), projecting from one side, which registers with the L-shaped groove a and forms therewith a bayonetjoint. Below the face of the stopper it has one side out under or formed into three walls, which meet at obtuse angles, as shown in Fig. 5. \V hen said stopper is in place, said walls, with the lip a inner adjacent wall of the neck, and shoulder a, form a crooked passage-way leading to the valve hereinafter described.

C denotes a funnel, made of aluminium or other suitable material, which forms the shell for the valve, its vertical walls fitting snugly within the neck and bent at right angles to form an annular flange 0, by which it is supported upon the shoulder a. The lower end of said funnel is turned upward and fastened into a washer 0, made of wood or other material, having an annular groove therein, into which is secured a rubber gasket 0 which bears in an annular groove formed in the lower wall of the bottleneck, forminga water-tight joint therewith. 0' denotes a narrow annular ledge brazed to the inner walls of the lower part of the funnel.

E denotes a pear-shaped valve the sides of which conform to the contracted portion of the funnel onto which it seats, as shown in Fig. 1.

E denotes a valve-stem depending from said valve. 6 denotes a thin fiat steel spring rigidly secured midway its length to said valvestem, crossing the same at right angles, and of a length slightly exceeding the diameter of the lower end of funnel.

F denotes a divided guard stoppcr suspended from the lower end of the valve-stem and adapted to fit snugly into the lower end of the funnel. It may be made of cork or consist of two hollow members made of aluminium and hermetically sealed.

In Fig. 7 we show a modification in the arrangement of guard-stopper F, in which G denotes a cork stopper mounted in a conicalshaped cup g upon a wooden base 9. valve stem passes through the cork and wooden base and is fastened to the bottom of the cap.

After the bottle is filled the funnel (1, containing the valve and its attachments, is pressed into the neck of the bottle, carrying with it the washer 0, until its gasket 0 fits into the annular groove in the lower partof the neck, when the flange 0 seats itself upon shoulder a. The stopper B is then fitted in position by placing the knob b in the vertical portion of groove a, pressing it down until said knob meets the horizontal portion, then turning the stopper until the knob traverses the length of this part of the groove. A prepared cement or other suitable material is then poured into the mouth of the groove, filling it and sealing the stopper in position. It will be seen that when the knob 6 reaches the extremity of the horizontal portion of groove (0 the cutunder portion of stopper B will register with The the mouth a and form a passage-Way for the escape of the liquid. As the bottle is tilted the valve assumes the position in Fig.6,caused by the pressure of the outflowing liquid upon it and upon the stopper F. The flat spring a limits the outward movement of the valve as against the liquid-pressure by coming in con tact with the lower end of the funnel; but should abnormal pressure be usedas. for example, by any one attempting to lift the valve off its seat -the spring 6 yields to greater pressure and is bowed, as shown in dotted lines in Fig. 1, its arm ends passing over the ledge as the stopper F is drawn up and closes the lower end of funnel. Thus the stopper may be securely locked in position. Said ledge may be omitted without departing from my invention, as generally the arms of the spring may give sufficient bind against the wall of the funnel to prevent stopper F being displaced when once pulled up. When the modified form of stopperGr is used, the cone-shaped cup when pulled up forces the stopper in the lower end of the funnel or shell, while the mouth of said cup fits over and around said lower end. The spring a may be dispensed with when this form of guard-stopper is used.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In a bottle-closure for non-refillable bottles, the combination of aneck having an an- I nular shoulder an offset or lip forming a mouth and an L-shaped groove,and a stopper having a lateral projection therein which registers with said L-shaped groove forming a bayonet joint therewith and a cut-under portion which registers with said lip to form a tortuous passageway leading into' the neck of the bottle.

2. A non-refillable bottle having a funnelshaped valve-shell and a valve which seats in the contracted portion of the side walls of the shell having a depending valve-stem adapted to project below said shell and a stopper fastened to said projecting end of the stem adapted to close the lower end of the shell.

3. A non-refillable bottle having a tapering valve-shell and a valve which seats itself in the side walls of the same, a washer fastened to the lower end of said shell forming a tight joint with the neck of the bottle, a stem depending from said valve having a stopper suspended therefrom which hangs below the shell and. adapted to close the lower end thereof, and a spring-arm secured to said stem cross ing the same at right angles adapted to limit the normal play of the valve, yield to abnormal pressure and lock said stopper in position when drawn up into the shell.
