REFILLING-PREVENTING STOPPER.

Application filed May 5, 1915.

To all whom it may concern Be it known that we, (1) WALTER M. SPnNDLovn and (2) KALMAN FOLDEAK, (1) a citizen of the Dominion of Canada and (2) a subject of the King of Hungary, residing at Brockville, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Refilling-Preventing Stoppers, of which the following is a specification.

This invention relates to certain new and useful improvements in refilling preventing stopper.

The primary object of the invention is to provide a stopper for such a container as a wine or liquor receptacle, the same being arranged to prevent a refilling thereof after the original contents have been extracted.

A further object of the invention is to provide a cheap device capable of being instantly locked within the neck of a fluid container whereby a small quantity of the fluid is trapped within the bottle neck and any tampering with the bottle structure or'its contents may be readily ascertained, while the structure prevents any refilling without some mutilation of the structure.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :-Figure 1 is a central longitudinal sectional view through a bottle neck provided with the present device. Figs. 2 and 3 are transverse sectional views of Fig. 1 taken upon lines IIII and III-III respectively. Fig. 4 is a perspective view of one of the valves, and Fig. 5 is a perspective view of the valve weight.

Referring more in detail to the drawings, it will be seen that the neck 10 of a bottle 11 is illustrated of substantially the usual form and having an annular groove 12 encircling the inner portion of the neck and adapted to receive a split locking ring 13 automatically therein when the tapered valve cage 14 which carries the said ring in a similar annular groove 15 is forcibly slid inwardly within the neck. The said cage 14:

is thus locked by means of the said ring 13 within the neck of the bottle. The cage 14; being tubular has a central bore formed into an outer and inner valve chamber 16 and 17 respectively by means of an inner end cap 18 having a central opening 19 therein and a substantially centrally positioned partition 20 having a central opening 21, the said partition and cap being substantially of the same form and dimensions, it being noted that each of the same is retained in place by means of a screw threaded engagement with the cage.

Each of the chambers 16 and 17 is provided with a valve of the form illustrated in Fig. 4 and consists of a rectangular plate 22 adapted to flatly seat over the openings 19 and 21. Corner posts 23 are perpendicularly arranged upon the plates 22 and are adapted for preventing a tilting of the valves and to guide the same in their movements as well as to limit the extent of opening movements thereof and preventing the plates from engaging the oppositely arranged perforated members which engagement would close the outlets for the bottle contents. A washer weight 24 is arranged within the outer chamber 16 in normal engagement resting upon the free ends of the valve guide posts 23 when the bottle is normally positioned upright. The outer end of the cage has an inwardly tapered flange 25 for providing a central fluid outlet 26 of substantially the same diameter and positioned in axial alinement with the openings in the cap and partition and the central opening 27 in the washer weight 24:.

The manner of positioning the valve cage in its locked engagement within the bottle neck has been heretofore described, the normal position of the elements being illustrated in Fig. l. lVhen desired to pour out the contents of the bottle, the bottle is tilted or inverted which movement unseats the two valve plates 22 from the openings 19 and 21 and allows the fluid to freely pass therethrough and also through the weight opening 27 and the cage outlet 26, it being understood that the washer weight 24 is slidably positioned within the cage bore, but fits the same with sufiicient closeness to prevent any tilting of the washer weight. When the contents is extracted it will be evident that any attempt to force fluid into the bottle through the neck would result in closing the two valves which would prevent the entrance of any fluid, while the valves would be further retained upon their seats by their own weight, when thebottle'is positioned upright. It will be also impossible to insert any instrument withinthe cage so as to hold both of the valves unseated at the same time, the complete device thereby preventing any unauthorizedrefilling' of the bottle after the original contents thereof has been removed.

lVhen the bottle is filled for the purpose of sale, this is done before the improved stopper zis inserted intheneck thereof and after the cage has been locked in place was described, the'innerchamber 117 -.is filled with fluidby slightly inverting'the bottle and this small quantity of fluid will remain trapped therein until the bottle contents is removed unless some tampering has been had with the inner valve for the purpose ofrefilling the bottleunauthorizedly jsothatthe absence of fluid from the chamber 17 Woulddemon- Copies of vthisvpatent may beobtained for shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless tobe understood that minor changes may be made therein without departing from the splrit and scope of the invention as claimed.

the cage, a cap fltted within the inner end,

of the cage, a partition secured within the cage and forming an inner fluid trapping chamber between the said partition and end cap, said partition andend cap and flange having axially alining similar sized outlet openings therethrough, rectangular valve plates mounted upon corresponding outer faces of the said partition and cap, outwardly projecting guide posts perpendicularly carried by the corners of the said plates,:and a perforated washer weight normallyiseated upon the free ends of the guide posts of the outer valve when the cage is in itsaupright position, the said weight closely fitting within the cage and having a central fluidoutlet opening therethrough in constant axialalinement-iwith and being substantially the same diameter as the aforementioned outlet openings.

In testimony whereof we aflix our signa-' tures.
