This invention relates to liquid containers having delivery spouts which are adjustable to operative and inoperative positions and through their movement operate valves for controlling The construction has various usesbut is herein disclosed as formed and dimensioned particularly for reception in domestic refrigerators.

A purpose of the invention is to provide a container of the class described with improvements permitting the drawing off of small portions of the liquid without allowing the remaining portion to become unnecessarily decarbonized, in the case of carbonated beverages, by the admission of more air than may be necessary to effect outward flow of the liquid. A further purpose of the invention is to provide for controlling the outward flow of the liquid with its vapor while under its own vapor pressure. Another purpose of the invention is to provide a head for the container which is so formed as to neatly receive a pivoted, combined spout and valve operating element. Another object of the invention is to provide valves under the control of the swinging spout, which valves successively move to open, rst to permit a flow of liquid if under pressure, and then to admit air to the container if necessary for allowing proper flow of liquid in case the liquid is not under the necessary pressure from weight and vapor or gas arising therefrom.

The objects of the invention are accomplished by means of a construction as illustrated, wherein:

Fig. 9 is an end view of the valve shown in Fig. 8.

Fig. 10 is a sectional detail of a check valve for preventing the outward ilow of vapor or liquid from the air inlet valve.

In its general features, the construction illustrated consists of an inner cylindrical container carried by an outer rectangular shell which is made in this form to prevent rolling. The closing head oi the inner container carries pivoted thereto, on a horizontal axis, a combined spout and valve operating means, and is made concave on its outer surface to receive the spout folded against it in protected lposition when the valves operated by the spout are in closed position. When the spout is swung downwardly the valves remain closed until the spout moves through, or preferably below, its horizontal position when the liquid ilow control valve rst gradually opens, and if the ow is not fast enough, further depression of the spout results in opening an upper check controlled air intake valve. This valve also serves to release vapor, if under pressure, to the spout.

In the drawings, the outer rectangular shell I has rounded corners and ts a similarly formed head 2 for. the inner cylindrical drawn metal container 3, which is separated from shell I by insulation 38. The shell is secured to the head by being crimped into depressions 4. The head 2 has an inner cylindrical flange 5 in threaded engagement with internal threads at the end of container 3. The head is dished inwardly as indicated at 6, and is a casting formed to receive a spout 'I pivoted therein. The head 2, container 3 and spout 'I may be made of some such material as aluminum magnesium alloys, which are believed not to have a detrimental effect on carbonated beverages such as draft beer.

The spout 1 is pivoted on a horizontal axis in a boss 8 formed at the lower end of the head. 'Ihe head also carries a spring pressed ball or plunger 9 for bearing against the lower end of the spout to make a tight sliding iit against the end of boss 8 at the shoulder III of the spout (Fig. 3) at the inner end of its hollow pivot shank II. 'I'he pressure of spring I2 bearing against ball 9 is regulated by screw I3. The head 2 is also provided with a lling plug I4 and a carrying handle I5 which spans the concave portion of the head and is secured thereto by the screws I6.

The head is formed and cored out to provide passageways II and I8 respectively for liquid, and gas or vapor from the container to the spout. Passageways are controlled by valves I9 and 20 and are held to their seats by springs 2l and 22. The valve springs are made of tempered aluminum magnesium alloy or other material plated or coated to prevent any detrimental effect on the liquid, and the valve faces are made of a composition which is suitable for the purpose and properly seals the openings. The springs 2| and 22 have their ends 23 and 24 clipped into notches 25 and 26 in the head. The valve stems 21 and 28 are engaged at their ends by shoulders 29 and 39 formed on the shank Il of spout 1. The lower end of the vent valve stem 28 has four small pressed up nubs 3| for fitting the hole 32 in the head. Otherwise both valves are kept in alinement with their seats by the springs 2l and 22.

The valve I9 controls the flow of liquid from the container through the hole 33 communicating with the spout. Valve 2G, if opened, will allow gas or vapor under pressure to ow downwardly to the spout in case the spout is lowered far enough to open the valve, and when the spout is in this position and there is no pressure within the container, air may flow inwardly past the valve 29 through openings 34 in the head 35 of a nipple 36. Outward spurting of gas through this nipple is prevented by check valve 3l. During shipment, the spout is kept closed by a screw cap 38 and is folded inwardly against the head, in which position the spout and the valves are seated.

In the use ot the construction it is rst steam cleaned through the filler plug opening. It is then lled and the plug ld is replaced. The spout is capped and folded against the head 2. The container is placed in a refrigerator with the head towards the front. Then to draw a portion of the liquid, the spout is swung downwardly to the horizontal position, or rather, slightly further as indicated by the broken lines I (Fig. l), in which position valve ll is held open by the shoulder 29 engaging the end of the valve stem. The liquid then flows through the spout under its own pressure, but if the liquid is well cooled the iow will slow up and the spout is further depressed until it reaches an angle of about 26 below the horizontal as indicated by the broken lines E (Fig. l), which is suiicient to open the upper valve 2i) and allow the necessary inflow of air to the container to continue the pressure required for further outward iiow of the liquid. If the spout is depressed to its lowerrnost position while there is still vapor pressure within the container, both the upper and lower valves permit outward flow to the spout. Under such circumstances the check 31 (Fig. 10) prevents outward spurting through the air inlets 34.

Although but one specific embodiment of this invention is herein shown and described, it is to be understood that details of the construction shown may be altered or omitted without departing from this invention as dened by the following claims:
