Description

July 31, 1934. s. GRAUER NONREFILLABLE BOTTLE- Filed Oct. 30, 1933 INVENTOR. Jc/on'von r uer @Y 4 A TTORNEYS.

Patented July 31, 1934 UNITED STATES PATENT OFFICE 4 Claims.

The invention relates to bottle stoppers of the type which when inserted in a bottle will make this non-refillable, and is a further improvement on the device shown'in my application for Letters' Patent, filed November 25, 1932, bearing Serial No. 644,172. It has for its main object to provide a bottle stopper which can. not be removed from the bottle when once inserted, and which positively prevents the introduction of any liquid or other substance into the bottle.

Another object is to provide a bottle stopper which may be adapted to make any type of bottle non-refillable without having to alter its shape or change its general appearance. .A further object is to provide a bottle stopper, of simple and inexpensive construction, which can be inserted in a bottle as readily, and with practically the sanzle means, as the ordinary cork now generally use These and various other objects and advantages will be readily understood from the following description and from the accompanying drawing of a preferred embodiment of the invention in which, however, modifications may be made without departing from the scope of the appended claims. In the drawing Fig. 1 is a fragmental and cross-sectional view of a-bottle with a stopper shown inserted therein; the view is taken on line 1--1, in Fig. 3;

Fig. 2 is a similar view showing the bottle tilted and the valves in the stopper in the open positions;

Fig. 3 is a. top viewoi Fig. 1;

Fig. 4 is a sectional top view taken on line in F Fig. 5 is a side elevation up the stopper; and

Fig. 6 is a modification of the valves.

Referring now to all the views, simultaneously, the stopper comprises a body member preferably formed of two

semi-circular halves

10 and 11 on each of which a half flange 12 is provided so that, when the two parts are assembled, a continuous flange is formed around the body member. A chamber 13 is formed in the stopper above flange 12, while another chamber 14 is formed in the lower end of the stopper. A concentric opening 15 leads from the upper chamber to the lower chamber and in this a valve stem 16 is free to slide.

The upper end of the valve stem is provided with a valve disk 1'? which is formed integrally with the stem, while the valve 18 is preferably slidingly mounted on the lower end of the valve stem and adapted to close an opening 19 which of the two partsmakln leads into the chamber 14. A plurality of radical grooves 20 are formed in the inner part of the body members and extend from the chamber 13'to the chamber 14 so as to form longitudinal passages through the body member. The valve disk 17 is of.v suiiicient diameter to close these passages. The body member parts are held together and secured tightly in the neck of the bottle 21 by a tubular member 22 made of resilient material, such as cork. The bottleis made with an annular recess 22 A against the bottom of which the flange 12 seats. The recess in the neck of the bottle may be made of sufiicient depth to make it possible to insert an ordinary cork in, addition to the stopper. When the bottle is in its upright and normal position, the

valves

17 and 18 close, the upper ends of the grooves 20 and the opening 19, respectively. The valves will remain in this position until, the bottle is tilted to the approximate position shown in Fig. 2. whereupon the valve stem, and consequently the valves, will slide so as to uncover the grooves 20-as well as the opening 19. The contents of the body will now flow freely through the opening 19, chamber 14, some of the passages 20, chamber 13 and through a plurality of openings 23 which leads from the chamber 13. While the liquid is flowing from the bottle, air is admitted to it through one or more of the openings 23 and through one or more of the passages 20. The movement of the valve disk 1'7 is limited by the top 24 of the chamber 13. An air vent 25 is preferably formed in this top and a plurality of small protrusions 26 are preferably formed on the upper faceof the valve disk 17 so as to prevent it from contacting directly with the top 24 and thus prevent the escape of air through the hole 25. As the flange 12is seated against the bottom of the recess 22, it is obviously impossible to push the stopper into the-bottle. Furthermore, this flange prevents the cork member from being destroyed or removed either by mechanical or chemical means. The chamber formed around the upper valve makes it impossible to hold this valve open so as to thereby refill the bottle. Furthermore, even if this valve should for some reason stick or otherwise stay open, the lower, sliding valve 18 would close the opening 19 and prevent any liquid from being introduced into the bottle. In the modification shown in Fig. 6 the lower valve 18 does not slide on the valve stem 16 but is moulded integrally with it. In some instances this construction is preferable. In other instances one or the other of the valves may be omitted. In case the upper housing is omitted and when the lower. valve is slidingly mounted on the valve stem, a detent 27 is formed on the valve stem to retain it in place when the bottle is tilted.

The present construction makes it easy to insert the stopper in a bottle and removes all danger of breakage; in that, a tubular tool may be used which engages directly on the flange and thus remove any danger of crushing the chamber 13 even when considerable pressure is needed for inserting the stopper.

It is evident that many modifications may be made in the device shown without departing from the scope of the appended claims and it is there-- fore to be understood that the illustration and description is primarily to show a preferred form. of the device which is simple and inexpensive in its construction and effective in its operation.

Having described my invention and its objects, what I claim as new. and wish to protect by Let ters Patent, is':

1. A bottle stopper for preventing the refilling of a bottle; comprising a body member insertable in the neck of a bottle; a plurality of passages formed longitudinally through said body member; a concentric opening formed in said body member; a valve stem, having a valve disk at its upper end of suflicient size to close all said passages, slidingly mounted in said opening; a chamber formed in the lower part of the body member; an orifice leading from the bottom of the body member to said chamber; a valve, slidingly mounted on the valve stem, for closing said orifice; and a housing, having a plurality of openings, formed on the upper part of the body member and in which said valve disk is contained.

2. A bottle stopper for preventing the refilling of a bottle; comprising a body member having an annular flange insertable in a recess in the upper part of the neck of a bottle; a plurality of passages formed longitudinally through said body member; a concentric opening formed in said body member; a valve stem, having a valve disk at its upper end of sufiicient size to close all said passages, slidingly mounted in said opening, a chamberformed in the lower part of' the body member; an orifice leading from the bottom of the body member to said chamber; a valve slidingly mounted on the valve stem, for closing mid orifice; a housing, having a plurality of openings, formed on the upper part of the body member and in which said valve disk is contained; and a resilient sleeve secured on the outside of the body member, below said flange, for securing the stopper in the neck of the bottle; the said hous ing being of smaller size than the recess in the neck of the bottle so as to allow a hollow tube to be engaged against the said flange in the insertion of the stopper in the bottle.

3. A bottle stopper for preventing the refilling of a bottle; comprising a body member having an; annular flange insertable in a recess in the upper part of the neck of a bottle; a plurality of passages formed longitudinally through said body member; a concentric opening formed in said body member; a valve stem, having a valve disk at its upper end of suflicient size to close all said passages, slidingly mounted in said opening; a chamber formed in the lower part of the body member; an orifice leading from the bottom of the body member to said chamber; a valve slidingly mounted on the valve stem, for closing said resilient sleeve securedon the outside of the body member, below said flange, for securing the stopper in the neck of the bottle; the recess in the neck of the bottle being of sufiicient depth to allow the insertion of a cork above the stopper itself.

4. A bottle stopper for preventing the refilling of a bottle; comprising a body member insertable in the neck of a bottle; a plurality of passages formed longitudinally through said body member; a concentric opening formed in said body member; a valve stem, having a valve disk at its upper end of sulficient size to close all said passages, slidingly mounted in said opening; a chamber formed in the lower part of the body member; an orifice leading from the bottom of the body member to said chamber; a valve, slidingly mounted on the valve stem, for closing said orifice; and a detent formed on the valve stem to prevent its dislodgment.
