MORITZ FORST AND JACOB ARMBAND, OF NEW YORK, N. Y.

NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 788,639, dated May 2, 1905. Application filed October 20, 1904. Serial No. 229,221.

To (all 10/1/0771, it may concern.-

Be it known that we, Monrrz Fons'r, a citizen of Austria, and JACOB ARMBAND, a citizen of the United States, both residents of New York city, Manhattan, county and State of New York, have invented new and useful Improvements in N on-Relillable Bottles,of which the following is a specification.

This invention relates to a bottle or similar receptacle which while preventing spurious refilling permits the ready discharge of the liquid.

In the accompanying drawings, Figure 1 is a vertical section through the upper part of a non-refillable bottle embodying our invention and showing the valve closed. Fig. 2 is a side view of the cylindrical plug; Fig. 3, a cross-section on line 3 3, Fig. l, and Fig. 4 a section similar to Fig. l and showing the valve open.

The letter a represents a bottle the neck a of which is contracted at its bottom to form a valve-seat (0 Within the neck a is permanently secured a cylindrical plug d by means of a rubber or cork gasket 0, that enters grooves a b of the neck a and plug I), respectively. The upper end of plug bis of a diameter to completely fill the neck, while the plug is reduced at its lower end, as at Z), to form a surrounding annular chamber (Z. This reduced lower end 6 of plug 1) terminates in a conical tip 6 surrounded by a chamber 6. From the bottom of reduced section 5 extends an annular flange 6, having slots 6, that establish communication between the chambers c and (Z. The chamber (Z in turn communicates with the outwardly-opening bore 6 of plug 6 by lateral perforations Z), arranged out of vertical alinemcnt with slots 72'. At its top the plug 6 terminates in a head 6, having a lower groove which receives the edge of neck a. \Vithin the chamber 0 there is free to play a hollow conical valve f, which closes againstseat a when the bottle is rigl'ited, Fig. l, and projects over conical tip 6 when the bottle is tilted, Fig. 4:. In the latter position the liquid is free to flow through chamber 0, slots 6 chamber-Jul, and perforations 6 into the bore 7) of plug 6 to be thence discharged.

It will be seen that by our invention a ready flow of the liquid is insured, while spurious refilling of the bottle is prevented.

WVhat we claim is 1. In a non-refillable bottle, a cylindrical plug having a bore, a reduced lower section, a conical tip, a slotted flange, and a series of lateral perforations entering the bore, combined with a hollow conical valve adapted to engage the tip, substantially as specified.

2. In a non-refillable bottle, a cylindrical plug having a bore, a reduced lower section, a conical tip, a slotted flange, a series of lateral perforations entering the bore, and a grooved head engaging the bottle-neck, combined with a hollow conical valve adapted to engage the tip, substantially as specified.

Signed by us at New York city, Manhattan, New York, this 18th day of October, 1904.
