My invention relates to a liquid dispensing device and more particularly to a liquid dispenser adapted to be used in connection with insulated containers for-liquids.

Picnic jugs and other similar containers such I as Dewar flasks sold under the trade name of Thermos bottles are adapted to contain hot or cold liquids and keep them at elevated or low temperatures for considerable periods of time. The dispensing of iluids from these jugs has been accompanied by the necessity of removing the cap either to pour liquids out or in the case of those containers provided with spigots to permit the venting of the vessel.

Air lines frequently employ insulated jugs for the serving of soups, coffee, iced tea, and the like. In airplanes, the motion of the plane makes it exceedingly difficult to dispense fluids from insulated jugs in the usual manner. When the jug is opened, either to remove liquid therefrom or to vent the same, its contents are often spilled.

One object of my invention is to provide a simple 4and expeditious means of dispensing fluids from heat insulated jugs and similar containers.

Another object of my invention is to provide a dispensing means which will seal the Vessel when liquids are not being withdrawn therefrom.

Other and further objects of my invention will appear from the following description.

In the accompanying drawing which forms part of the instant specification and is to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views;

Figure 1 is an elevation of a heat insulated jug, equipped with one embodiment of my invention.

Figure 2 is an enlarged sectional view, with parts broken away, taken on the line 2-2 of Figure 1, with the parts in jug-sealing position.

Figure 3 is a fragmentary side elevation, with parts in section, on an enlarged scale, taken 130 from the section shown in Figure 2, with the parts in fluid dispensing position.

Referring now to the drawing, the container I may be of any suitable type such as a ceramic or glass vessel 2, which is provided with a heat insulating blanket 3, protected by a sheet metal casing 4. A cap 5, provided with a sealing stopper 6 of any vsuitable construction, is adapted to be screwed onto the neck of the jug by means of screw threads 1. Secured to the cap in any suitable manner is an assembly which embodies my invention. It comprises a casting &i,`proY vided `with a ilange 9 which may be riveted, brazed, welded or otherwise secured to the cap. The casting 8 is formed with a duct lil, ending in a spigot II through whichV the liquid within vthe jug is adapted to flow in removing it from the jug. A vertical bore I2 is likewise formed in the casting. A tube I3 passes into the bore I2 and extends upwardly into the jug, as can readily be seen by reference'to Figure 2. Secured to the tube I3 is a valve holding member I4 in which a valve I5 is positioned. The casting 8 is formed with an annular raised portion I6 which forms a valve seat preventing the ilow of liquid vfrom the jug. The tube I3 may be made of any suitable materialsu'ch as stainless steel or, if desired, a suitable plastic material. Housed within the tube I3 I provide a r'od I'I, to the lower end of which is secured a plug I8 by means of a screw I9, threaded in the lower end of the rod I1. The upper end of rod I 1 carries a valve holding member I9', in which a valve 2u is positioned. The upper periphery of the tube I3 acts as a valve seat, against which the valve 2i] seals. The valve assembly is secured to the upper end of rod II by means of a screw 2|. A spring 22 within the bore I2, acting against the plug I8, urges the rod I'I downwardly, thus seating the valve 20 on the upper end or tube I3. This forces tube I3 downwardly and seats valve I5 against its seat I6. The lower end of tube I3 within the bore I2 is provided with a plurality of openings 23. The plug I8 is formed with a pair of lugs 24, extending outwardly through slots 25 formed in the sides of the bore I2. A bifurcated lever 25 straddles the spigot II and is pivoted to the casting 8 by pivot pin 2l. An operating handle 28 is secured .to the bifurcated lever 26 by means of a screw 29. Arms 3E] of the lever 23 engage the lugs 24 in the plug I8.

In operation, when it is desired to dispense liquid from the jug I, the lever 26 is operated, rotating it about its pivot pin 2l. The arms 30, in engagement with the lugs 2li, raise the plug I8, thus raising the rod II. It will be noted that the lower end of tube I3 is spaced away from the plug I8 so that there is an upward movement of the rod with respect to the tube I3, against the action of the spring 22. This rst movement raises the valve 23 from its seat and Vents the interior of the jug above the liquid level therein. Continued motion of the plug I8 upwardly under the inuence of the lever 26 against the action of the spring 22 then moves the tube I3 upwardly, together with the rod I'I. It will be observedV that the rod I1 maintains its relative position with tube I3; that is, that the air vent at the top opens. The upward movement of the tube I3 lifts the valve I5 from its seat and permits liquid to flow out of the spigot II. As the liquid ows out of the spigot II, air from the duct I8 through the slots 25 in the duct enters `the openings 23 in the tube I3 and ilows upwardly through the tube to the space above the liquid in the jug. Some air will also pass upwardly through the space between the tube I3 and the casting 8. This air flows into the eduction liquid by induction of its flow past the annular space between the casting 8 and the tube I3. The ow of air into the eduction liquid prevents leakage of liquid into the bore I2. When the lever 26 is released, the spring 22 will rst permit the valve I to cease shutting ol the liquid flow, then seats the valve 20, sealing off the vent tube. The jug is thus automatically sealed and no liquid will escape, irrespective of the motion of the jug.

It will be seen that I have accomplished the objects of my invention. VI have provided a simple and expeditious liquid dispensing device for heat insulated jugs and the like, which automatically vents the jug when liquid is being withdrawn therefrom and in which the vent is sealed when liquid is not being withdrawn.

It will be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations. This is contemplated by and is within the scope of my claims.y It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood that my invention is not to be limited to the specific details shown and described.

Having thus described my invention, I claim:

1. In combination with a container adapted to contain liquid, a spigot, a liquid Valve for controlling the flow of liquid `from said container through said spigot, a vertical tube extending upwardly into said container, means for mounting said liquid valve on said tube, a vent valve sealing the upper end of said tube, a rod positioned within said tube, means for securing said ventV valve to the upper end of said rod, meansV carried by the lower end of said 'rod normally out of engagement with the lower end of said tube,

and means for moving said rod upwardly, the construction being such that the initial movement of said rod will open said vent and continued movement of said rod will move said tube upwardly to open said liquid valve.

2. In combination with a container adapted to contain liquid, said container formed with an opening, a liquid closure valve for said opening, a spigot having communication with the interior of said container through said opening and controlled said liquid closure valve, a tube extending through said opening into said container, said liquid closure valve mounted about seid tube, a vent valv-e sealing the upper end of said tube, an elongated member extending through said tube and secured to said vent valve, spring means for urging said elongated member downwardly to seat said vent valve upon said tube and to urge said tube downwardly whereby to seat said liquid closure valve, and means for lifting said vent valve and liquid closure valve in succession.
