The limit of inward movedescription of a present preferred embodiment ,ment of the spout isdetermined by engagement thereof proceeds. of the bead 20 with the portion i5 of the neck II,

In the accompanying drawing I have shown a. and the limit of outward movement of the spout present preferred embodiment of the invention, is determined by engagement of the flange 2| in which with the portion ii of the annulus H. The spout Figure 1 is a partial central vertical cross-secis preferably made of light gauge sheet metal tional view through a spouted sheet metal shipand at opposed points the metal of the spout is ping container, the cross section also being taken pressed inwardly to-provide opposed venting pascentrally through the inlet and outlet passage sages 22 to allow air to pass between the outside 5 and the spout; and the space between the spout and the interior of the neck i2. This space, shown at 23 in Figure 1, may be termed a venting passage and is disposed within or forms a part of the inlet and outlet passage of the container, which is defined by the neck i2 but is outside the spout or liquid con-' duit M. This venting passage 23 is, as above indicated, connected with the outside by the passages 22 formed at the outside of the spout i4 and which permit the passage of air to and from the outside between the spout and the neck l2.

The annulus l3 has a portion 24 which extends inwardly of the container from the inlet and outlet passage as shown in Figures 1 and 3. In the portion 24 is provided an opening 25 through which passes the end of a vent conduit or tube 26. The vent tube 26 extends thence generally transversely and upwardly within the container and has its opposite end welded or soldered to the cover at 21. 1 Q The lower or inner surface of the annulus i3 inclined with respect to the axis of the spout i4 as indicated by the dotted lines 28 in Figure 1. Thus at the portion of the annulus diametrically opposite the portion 24 the annulus terminates in a direction inwardly of the container at a point nearer the inlet and outlet passage than the portion 24 thereof. This construction of the annulus i3 obviates the trapping of air outside the annulus and against the inside of the top of the cover. Also, as the portion 24 of the annulus i3 is nearest the center of the cover the diametrically opposed portion of the annulus is nearest the cover rim and when contents of the container are being poured out there is a minimum of interference with the flow of such contents into the spout i4, which when the contents are poured out will be in its outward position as shown in dotted lines in Figure 1. It will be understood that when pouring out the contentsof the container the container will ordinarily be tilted toward the left viewing Figures 1 and 2 of the drawing.

A hail 29 for manipulating the spout I4 is prvided near the top of the spout, such bail consisting simply of a bent piece of wire having its ends serving as trunnions and passing through holes in the sheet metal spout at the opposed inwardly bent portions 22 thereof.

The container may be filled with the spout i4 in either its inward or its outward position as may be most convenient. It may be filled by'introducing into the top of the spout a filler tube which substantially, closes the spout so that suiiicient venting cannot be had through the spout itself. The introduction of liquid into the container forces the air in the container upwardly where it enters the upper end of the vent tube 26. It passes through the vent tube 26 into the venting passage 23 and thence out through the passages provided by the inwardly bent portions 22 of the spout i4.

When the contents of the container are being poured out the spout l4 will ordinarily occupy its outward position as shown in dotted lines in Figure 1. The liquid poured out is displaced by air entering the container through the same path as above described through which the air is forced out when the container is filled except that the air passes in-the opposite direction.

While I have shown and described a present preferred embodiment of the invention, it is to be distinctly understood that the same is not limited thereto but may be otherwise variously embodied within the scope of the following claims.
