'7 Claims. (01. 225-1) This invention relates to new and useful improvements in liquid dispensing containers.

In order to withdraw liquids such as beer in bulk quantities from kegs and other containers,

it is necessary to punch out a bung, or tap a. hole in the container to receive a dispensing pump. However, immediately this hole is made, carbon dioxide gas will escape through it to make that liquid more or less flat for beverage purposes.

Furthermore, when a pump is inserted in the hole, air will be discharged therefrom through the liquid, forcing the carbon dioxide gas out of the liquid and introducing therein bacteria and other foreign matter.

If the container holds alcohol or other commercial liquids, the air vent which is drilled or punched in it to release the liquid will become a means through which some of the vapors will escape, thus causing waste.

It is one of the principal objects of our invention to provide a hermetically sealed container from which liquids in bulk quantities may be freely dispensed without waste, contamination or deterioration by automatically introducing air into the receptacle without aerating the liquid therein. If beer is dispensed, carbon dioxide gas is not released, except that held in liquid solution is discharged, nor does the air pass through the liquid to leave therein bacteria and other foreign matter to contaminate it. The container remains hermetically sealed while the air is introduced through the control valve into it to discharge the liquid in a substantially whole and uniform manner through the same valve.

It is another object of our invention to provide a spigot through which air or gas may be introduced into a container, and the liquid withdrawn from it, without that air or gas coming in contact with the liquid in the spigot. The

spigot not only admits free air or gas to the container, to displace the fluid, but at the same time discharges that liquid from the container in a controlled or continuous stream free from any bubbles save those caused by the air or gas dissolved within the liquid itself.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawing illustrating our invention, Figure l is a longitudinal sectional view taken through a liquid container in which our fluid dispensing means have been installed. Figure 2 is a front view of said container, showing the spigot for admitting air to, and discharging the liquid from, the container. Figure 3 is a front vertical sectional view taken through the spigot. And Figure 4 is a side, vertical sectional view taken through the same.

Referring to the accompanying drawing for a detailed description of our invention, the numeral 5 1 designates a can or container I filled with a liquid to be dispensed in bulk quantities therefrom. Formed in the head or top 2 of this container is a hole 3, through which the liquid to be dispensed is introduced into the container. 10 This hole is closed by a cork stopper 3 pressed below ribs 3 to make it non-removable after the container has been filled.

Formed in the head 2 of the container between the filling aperture and a side wall thereof, is 16 a raised portion 4 in which an air inlet aperture and a liquid discharge opening are formed. Projecting through the air inlet aperture in the raised portion 4 of the head 2 is the outer end of a tubular line or projection 5 on the lower 0 end of a tube or standpipe 6 that extends upwardly into the liquid in the container. At its extreme lower end the tube 6 communicates with the inner end portion of a horizontal liquid discharge tube or line I that projects with the air 25 line 5 through the liquid discharge opening in the raised portion 4 of the'head 2.

The tubes 5, 6 and I are preferably made up as an integral structure, to the outer ends of the air and liquid line parts 5 and I of which 30 a spigot 8 is attached. This spigot comprises a conical shell 9, open at the bottom and the top, and formed in its circular wall with an upper aperture into which the outer end of the air line 5 is fitted, and with a larger hole below to 35 receive the outer end of the liquid line 1. R0- tatably fitted within the shell 9 is a hollow plug I I] having a flanged top II to which the shank of a turning ear I2 is hingedly attached. The top portion of the plug I0, which is its air inlet 40 part, is hermetically sealed from its lower, or fluid discharge portion by a horizontal partition I3.

Formed in the wall of the plug I0 above the partition I3 therein, is an air outlet opening I4 45 which is adapted to be brought into registry with the outer end of the air line 5 by turning the plug.

Air enters the top portion of the plug through a notch I 4 in the top edge of the shell 9, and 5 holes I5 in the plug, flowing therefrom through the outlet hole I4 into the air line 5. The partition I3 prevents this air from coming in contact, in the spigot, with the liquid which is discharged from the lower end of the latter when it 55' i rne to bring an op'ening l5 therein in (39m; unication 'with the Outer end of the dispensin I "tubelf e i :In operation, thecontainer is shown inja'dis-g,
