ATTORNEY' raar LAURENCE F. WATKINS AND GEORGE WILLIAM WILTON, OFvWELLINGTON, NEIN' I' ZEALAND. f
i i Application filed June 24,'
To all 'whom t 'may concern n Be it known that we, LAURENCE FREDER- IGK VVA'rKrNs and GEORGE IVILLIAM VVILTON, citizens of the British Empire, residing at Vellington, New Zealand, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification. f
The object of this invention is to provide a stopper for containers whereby the contents of a container may be sealed therein or discharged therefrom drop by drop or in a continuous stream as desired.
The invention is illustrated in the accompanying drawings in which Figure 1 is a sectional elevation showing the stopper acting as a seal of the contents in a container,
Fig. 2 is a sectional elevation showing the stopper acting as a discharger of the contents of the container drop by drop or in a continuous stream, Y
Fig. 3 is a sectional elevation of a modification of the stopper. v
The invention consists in the features and combinations and arrangements of parts hereinafter described and more particularly pointed out in the claims.
In the drawings, Figs. 1 and 2, is shown a container 1 closed by a cork 2 having a passage 3 perforated through it either when secured in a filled container or prior to being inserted therein. In the passage 3 is inserted so as to t tightly yet allow-of its gradual up and down movement a member consisting of two tubes 5, 6 preferably placed side by side and secured together. The lower ends of these tubes are closed by a closure 7 and in the side of one tube 5 near the closure 7 a small orifice Sis perforated such asY to permit the contents of the container being discharged therethrough drop by drop. In the side of the other tube 6 near the closure 7 a large orifice 9 is nerforated such as to ermit of the contents of the container being discharged there- Y through in a continuous stream. The tubes preferably terminate incurved outlets 10, 11 but will act when straight throughout. Secured on the outside of the tubes 5, 6 isV a flange 12 whichV serves with thel top of the cork 2 the purpose of arresting the downward movement of the tubese The tubes Specification ofiLetters Patent.

may be also moved up and down in the cork by means of a screw 13-Fig. 3 externally threaded on them. The small orifice for discharging the contents of the container by drops may be at either end of one of the tubes 5 or be formed by a constricted passage 14 shown in Fig. 3 wherein both orifices 8t and 9 near the closure 7 are made large.
In operation, the cork secured in any filled container is perforated by any suitable tool and the tube element is inserted therein so that its closure 7 is within the cork at its lower end as shown in Fig. 1. In this position the contents of the container remain sealed within it and cannot escape therefrom. When it is desired to discharge the contents by drops or in a continuous stream the tube element is gradually lowered into the container until the fiange 12 thereon is arrested by the top of the cork. The container is then tilted with the tube 6 lowermost-this tube having a large orifice 9 and air being admitted to the container through the orifice 8 inthe other tube 5 thereupon discharges thev contents of the container in a stream.
Then the container is tilted so that the tube 5 having a small orifice 8 is lowermost air is admitted to the container through the orifice 9 whereupon the contents of the container are discharged drop by drop. The container issealed again by gradually raising` the tube element until its closure iswithin the cork as originally placed and shown in Fig. 1.
In cases where the contents are liable to choke, instead of the small orifice 8 a large one as S"L is used and discharge by drops is effected by placing the point of a finger on one of the outlets and periodically raising it so that the contents drop out of the other outlet. That other outlet in that case is provided with a pointed end reducing its size.
We claim 1. Ina bottle stopper, the combination with an axially bored cork, of a tube member longitudinally slidable in the bore of the cork, said tube member having unobstructed passage therethrough and oppositely disposed lateral openings adjacent its inner end, and a closure for the extreme inner end of such tube, the longitudinal movement of the tube in the cork controlling` the discharge through the tube.
2. In a bottle stopper, the combination With an axially bored cork, of a tube member longitudinally slidable in the bore orA the cork, said tube member comprising a pair of tubes extending parallel to each other apart oi their extent and having di- V i verging discharge ends, said tubes also having adjacent their inner ends oopositely disposed inlet openings differing in sizel in their lateral Walls, and a closure for the extreme inner end of said tube member.
In testimony whereof We have hereunto 15 set our hands in presence of two subscribing Witnesses.
