Application November 3, 1932, Serial No. 64l,ll2l= 3 Claims. (Cl. 221-11) This invention relates to new and useful improvements in pouring spouts for containers.

The principal object of the invention is-to provide a pouring spout which will pour and accurately control a stream of liquid from a container, without gurgling caused by the back flow of air from the orifice into the top of the con-'- tainer. I A further object of the invention is to provide a very simple self-contained unit which includes a protruding pouring spout which normally is contained within the can or drum itself.

It is further contemplated to provide the standard rolled edge beaded nozzle with a drawn plug closure equipped with a closing seal which makes the cj lgppnjefillable as a package until the original seals and sealing machine are available.

In detail the design has been so made as to prevent the trapping of air inthe top of the can atany angular tilting position. If the can is full of liquid and the spout is pulled out to the pouring position, it is impossible to cause the liquid to trap air in the can as it flows out through the spout. This prevents the gurgling which is so troublesome in pouring liquids from ordinary This effect is containers with circular nozzles. obtained regardless of the In the drawings;-- Fig. 1 is a perspectiveview of a container with the improved pouring nozzle projecting therefrom and in a pouring position, the plug and seal having been remove I Fig. 2 is a sectional view showing the position of the pouring spout nozzle, plug and seal when the spout is sealed inside of the container. in

Fig. 6 is a diagrammatic view showing the shape of the stream of liquid as it passes from the spout level of the liquid and the air pocket condi-' pouring spout for a container having a projecting nozzle of standard design except that it 'is of a special elongated cross section which is fundamental with the results of perfect pouring.v

The elongated nozzle is so mounted in the container as to provide a slot which if a vertical plane is passed through its long axis when the container is sitting level or upright as shown in Figs. 2 and 3, said plane will be at right angles to the level of the liquid in the container. Furthermore, it is contemplated to provide a pouring spout which can be pulled out through the slotted nozzle into a pouring position. This pouring spout is preferably of a purely channel type which provides side guiding flanges and a pouring edge through which the liquid flows smoothly and without top friction. There are two features which are essential in the perfect pouring of a liquid through an orifice, the one being that the liquid flows freely and without excessive friction through a weir type notch rather than through a completely closed opening such as a cylindrical pouring spout. It is a well known fact in hydraulics that a liquid flowing through an orifice with its top .level free'and exposed only to air rather than a as to the passage of the liquid and for the inflow of air over the surface of the liquid to fill the space emptied in the container.

In the drawings similar reference numerals refer to similar parts.

A container I having a head 2 is provided with a nozzle 3 upturned integrally therefrom and providing. an orifice or passage through which the container may be discharged and vented when in a tilted pouring position as shown in Figs. 4 and 5. The nozzle 3 is preferably of elongated shape, thereby giving the discharge and venting means referred to similar shape. This means is positioned so that a normal plane passing through its major axis when the container is in said tilted pouring position will be substantially at right, angles to the pouring level of the liquid and also intersect said level to locate the upper portion of the passage or orifice above the level for free venting of the container and to locate'the remaining portion of the passage below the level for the discharge of the container. A beadedliner shell 4 with an outwardly turned flange 5 is securely pressed on to the nozzle 3 and the container head 2. Plug 6 is made to a flange flt in the top of the beaded portion of the liner shell 4. The plug has a flange I which rests upon the bead of the liner 4. Between the flange 1 and the'bead of the liner 4 is inserted a gasket 8 made of rubber or other suitable material for sealing in the contents of the can and a metallic seal 9 having downwardly turned edges 9a is pressed over the plug 6 and clinched in position with a mechanical sealing machine. The seal is made from thin metal and is provided with tongues ll cut therefrom so as to act as tabs to be pulled off by hand when the can is opened. A pouring spout I of a channel design is hinged to the outwardly turned flange 5 of the liner shell 4. The pouring spout is made by forming a piece of sheet metal'to conform in cross section closely to the shape of the elongated nozzle and comprises a pouring edge of cylindrical shape with two sides protruding upward therefrom to form side guides to restrain and guide the liquid to the pouring edge. These sides terminate in outwardly turned flanges. ll of the spout 10. To provide a tight fit between the pouring spout and the inner face of the container a U gasket 'I2 is fastened to the pouring spout flanges ll. spout in position after it has been pulled through the nozzle two slight projections l3 are provided on the side walls of the pouring spout and at such a position as to engage the bead of the nozzle. The pouring spout Ill snaps into place whereupon these projections l3 lock it against return. When the container is packed, being filled with oil or other liquid, the pouring spout hangs downward within the nozzle of the container, the, same usually being immersed in the liquid. This spout is entirely self draining within the container and is wiped clean on its sides when pulled out for use, making it very valuable for food products.

When theconsumer receives the shipment the package is opened by stripping the metal seal 9 from the top of the nozzle 3 and tearing the tabs I4 away by hand. The plug is then removed breaking the gasket seal 8 of the plug flange against the nozzle bead. The pouring spout is then exposed to view and it is only necessary to pull it upward through the nozzle into its locked protruding position; With the nozzle in this position the can is tilted so that the level of the liquid is substantially at right angles to a normal plane passing through the major axis of the elongated nozzle..

It is obvious that many other designs involving different details of construction might be made with these principles but a preferred embodiment has been shown and these alterations would not In order to hold the pouring depart from the spirit of the invention as set forth in the appended claims.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is;

I. A container of the character described, comprising a body having a top wall having an opening therein, a nozzle carried by the top wall about said opening and projecting outwardly therefrom, said nozzzle having an outer member and an interfitting liner shell, said liner having its outer end fitting over the outer end of the outer memberof the nozzle and having a flange at its inner endfltting in the-container about the opening in the top wall, and a pouring spout hingedly connected to said flange, said spout being swingable from a position within the container to a position extending through the opening and the nozzle.

2. A container of the character described, comprising a body having atop, wall having an opening therein, a nozzle carried by said top wall about said opening and projecting outwardly therefrom, said nozzle having an outer member and an interfitting liner shell, said liner having a bead at its outer end fitting over the outer end of the outer member of the nozzle and having a flange at its inner end fitting in the container about the opening in the top wall, a pouring spout hingedly connected to said flange, said spout being swingable from a position within the container to a. pouring position extending through the opening and the nozzle, and a closure for the opening, said closure having a member flttable over the outer end of the nozzle and interconnected with the head on the liner.

3. A container of the character described, comprising a body having a top wall'havingan open;
