NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent N0, 784, 941, dated March 14, 1905.

Application filed April 22, 1904. Serial No, 204,492.

To all whom if may concern,.-

Beit known that I, FRANCIS STEPHEN HEE- FERNAN, a citizen of' the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in NonRefillable Bottles, ofl which the following is a specification.

My invention relates to an improved form of check-valve adapted particularly for use in connection with bottles to prevent the refilling' 'of the same, but which may be used for other purposes.

In the accompanying drawings, which illustrate my invention, Figure I is a central vertical section through a bottle having my iinproved stopper and check-valve arranged therein. Fig. 2 is a similar view through the upper part of the bottle inverted.. Fig. 3 is a section on the line A B of' Fig. l. Fig.l is a section on the line (d D of Fig. l looking downward; and Figs. 5, 6, and 7 are elevations of the check-valve, valve-seat, and the body of the stopper, respectively.

Referring to the drawings, A indicates a bottle which may be of any usual form, and A indicates the neck of the bottle, within which is arranged a stopper comprising a body portion or plug B, having a cavity I, within which is arranged a check-valve C, the purpose of the check-valve being to permit the outfiow of liquid from the bottle and to prevent refilling of the same. An outlet-opening Vor bore Q extends from the cavity l to the upper or outer end of the body of' the stopper, and an opening or port 3 extends centrally through a valve-seat 4 at the inner or lower end of the stopper-,connecting the cavity l with the interior of the bottle. The cavity l is tubular, and the Valve C is circular in cross-section and fits closely within the walls of the cavity, but is free to move longitudinally therein when the bottle is inverted. The 'upper side ofY the valve is concaved or dished, as indicated by the numeral 5, 'and a circular series of ports or openings 6 extend from this concave face of the valve through to its lower side. The combined cross-sectional areas ofthe ports 6 are preferably made equal to the cross-sectional area of' the opening 2 or the port 3. A projection 7 on the lower face of the check-valve normally fits within and closes the port 3, and the remainder 'of' the lower surface of the valve is perfectly fiat, as shown, so that when the valve is against its seat the ports 6 in the valve will be closed thereby to prevent the admission of liquid through the valve into the bottle. When the bottle is inverted, however, as shown in Fig. 2, the valve leaves its seat by the force of gravity or by the pressure of the liquid within the bottle, or both, and drops to the other end of the cavity l. The Iianges 5, which surround the concave face of the valve, then support the valve, and the liquid may flow from the port 3 through the openings 6 in the valve, thence through the space or cavity 8 formed between the concave face of the valve and the outer or solid end of the stopper, and thence through the outlet-opening 2. The space 0r cavity 8 may be enlarged by forming a recess 8 in the body of thestopper, as shown.

In practice it will be understood that the bottle is first filled with liquid, and the stopper, complete with its check-valve, is then secured in position, after which the contents of the bottle may be poured out; butrefilling will be prevented. In order to hold the stopper in place, the body portion- B is provided with an annular groove 9 and a longitudinal groove 10, extending from its outer end to said annular groove. The interior ofI the bottlc-neck also has an annular groove 9L and a longitudinal groove l0, which register with the corresponding grooves 9 and lO in the body of the stopper when the latter is in position. The stopper is held firmly in place and liermetically sealed by a liquid cementing or plastic material of' any suitable kind, which is poured into the registering grooves IO and 10 and flows into and fills the annular registering grooves 9 and 9. After the cementing material becomes hardened it will be seen that the stopper becomes permanently secured in place by an air and liquid tight joint. The valve-seatLL is similarly secured in place within the lower end of the stopper-body by means of suitable cementing material poured into an annular space ll through an opening I2, said IOO space and opening being formed by registering grooves in the interior wall of the stopper-body and in the periphery ot the valveseat.

The stopper-body or plug and the valve when used in a bottle are preferably made of glass; but these parts, if desired, may be made otl non-oxidizable metal or any other suitable material which will not be injuriously acted upon by the liquid or which will not affect the liquid. VIt will also be apparent that the stopper-body and check-valve lnay be used in steam, water, and other pipes to permit the outfiow of liuids and prevent the return iiow, and l do not wish to limit my invention to its use in connection with bottles, although it is so shown in the drawings.

Having described my invention, what l claim, and desire to secure by Letters Patent, is

ln a device ol the character described, a plugI adapted to lit into a tubular body, said plug havingI a cavity therein and an outlet-opening extending centrally from the outer endl of said cavity to the outer end of the plug, and having also a i'lat valve-seat at its inner end provided with a central port, and a check-valve fitting' closely within the lateral walls of said cavity, said valve having a concave outer face and an inner face adapted to tit against said Valve-seat, and having one or more openings extending from its concave face to its inner face, said openings being out ot' line with the port and arranged so that their inner ends will be closed by the valve-seat in the normal position of the Valve.

Signed at Springfield, in the county o't' Greene and State of Missouri, this 19th day of April, 1904.
