AWOK/VE) United States Patent POURING SPOUTS FOR LIQUID CONTAINERS Carl Rasmussen, Bergen, Norway Application November 12, 1952, Serial No. 319,945

Claims priority, application Norway November 12, 1951 Claims. (Cl. 222-538)- The present invention relates to liquid containers and more particularly to pouring spouts for such containers.

Sheet metal containers of the type generally used for oil and other liquids are commonly provided with a raised pouring neck to which it IS known to attach a pouring spout to obtain better pouring facil ties. pouring necks often have outwardly extending annular lips or flanges at their upper rims. When containers of this kind are delivered from the factory filled w1th llqllld, they are usually sealed by a sheet metal seal over the pouring opening, a circumferential portion of such seal being crimped or folded around and under the lip or flange which is provided 'at the top of the neck for holding the seal in place. When it is desired to pour the liquld from the container, the seal is broken, and the pouring spout attached to the pouring neck. Such pouring spout must be sent, together with the container, be ng attached to the container with a temporary connect1on, for example a wire or string. It will be understood, however, that in such cases the pouring neck may easily become lost during shipment. It has also been proposed to provide the pouring neck with a permanently attached pouring spout. In practice, however, it has not been found possible to seal the neck of the container in the manner described above because, with the pouring spout permanently attached to the neck, the sealing tool does not have suflicient room to operate in applying the seal. Such containers must therefore be sealed in other ways which are less advantageous.

It is an object of the present invention to prov de an improved pouring spout so that the pourmg opening of the raised pouring neck may be sealed by means of a sheet metal seal crimped or folded over and around the top rim of the neck. In accordance with the invention, this is achieved by mounting the pouring spout on a collar which is substantially shorter than the neck of the container so as to be movable between a lower, or inoperative, position adjacent the top of the container and a raised, or operative, position adjacent the top of the neck. When the collar is in its inoperative position, the neck may be sealed in the above mentioned manner for shipment or storage. After such seal has been removed by the consumer, the collar carrying the pouring spout may be lifted to its operative pouring position and held in place on the pouring neck by the friction between the collar and the neck. Preferably, the pouring neck is made slightly conical with the walls diverging upwardly. By making the collar also conical, it will be held securely in its operative position simply by the friction between the collar and the neck and the resiliency of the sheet metals of which the neck and collar are formed.

A further characteristic feature of the invention is that the collar carrying the pouring spout is provided in its upper portion with an annular groove the cross section of which corresponds with the cross section of an outwardly projecting lip or flange provided at the top of the neck. When the collar is in its raised position, the rim of the neck seats in the annular groove so that the pouring spout is positioned substantially even with the top of the rim.

The nature and advantages of the invention will be more fully understood from the following description and claims in conjunction with the accompanying drawing, in which:

Fig. 1 is a perspective view of the top of a sheet metal Such.

container with a pouring neck and a pouring spout in accordance with the invention.

Fig. 2 is a vertical section through the pouring neck and pouring spout, the former being sealed and the latter being in its inoperative position for shipment or storage.

Fig. 3 is a vertical section through the pouring neck and pouring spout, the seal being removed and the spout being in its operative position.

In the drawings, the reference numeral 1 indicates the top of a sheet metal container of the type usually employed for liquids. The container is provided with a rasied pouring neck 2. The pouring neck is slightly conical, or tapered with its larger end up, and is soldered or otherwise permanently secured to the top 1 of the container. The walls of the pouring neck thus diverge in an upward direction. At the top of the neck, there is provided an outwardly projecting annular rim or flange 3 which is shown as a rolled edge. In the pouring opening, there is inserted a plug 4 as a temporary closure. The plug is shown as being formed of sheet metal and has an inturned rolled edge, frusto-conical side walls and a flat bottom. The pouring opening is sealed by a sheet metal seal 5 which is crimped or folded around and under the rim or lip 3 and removably covers the pouring opening of the neck 2, as shown in Figs. 1 and 2 of the drawings.

Around the pouring neck 2, there is provided a pouring member comprising a collar 6 and an outwardly extending pouring spout 8. The upper part of the collar is formed with an annular groove or recess 7 the cross section of which corresponds with the cross section of the annular flange or lip 3 of the neck. The collar 6 is slightly tapered or conical and its height is substantially less than the height of the neck, for example about half the height of the neck. The pouring spout 8 is substantially U-form or trough shaped in cross section and extends outwardly from the groove 7. It will be understood that the exact shape of the

pouring spout member

6, 7, 8 may be modified and that this member is not limited to the specific shape shown by way of example in the drawing. The spout member is preferably stamped from sheet metal in a single piece and is placed around the pouring neck before the same is soldered or otherwise permanently secured to the container.

In Figs. 1 and 2, the pouring spout member is shown in its lower, or inoperative, position. In this position, there is enough room above the pouring spout member for the sealing tool to obtain a good grip around and under the annular lip or flange 3 during the sealing operation without being impeded by the pouring spout member. The pouring spout member remains in its inoperative position during storage and shipment of the filled container.

After the seal 5 and the temporary cap closure 4 have been removed by the consumer, the pouring spout member is raised to its operative position, shown in Fig. 3, whereby the collar surrounds the upper portion of the neck and the annular rim 3 of the neck seats in the annular groove 7 of the pouring spout member. The diameter of the collar 6 is such that, when the pouring spout member is in its raised position, the collar fits tightly on the neck so as to provide a fluid-tight joint and to hold the pouring spout member in place by the resiliency of the sheet metal parts and the friction between them. There is hence no need of other locking means for retaining the pouring spout member in its pouring, or operative, position. The closure 4 may be reinserted in the neck to close the container, for example after part of the liquid has been poured out. The pouring member may be kept in its pouring position or, if desired, it can be returned to its inoperative position after each pouring operation.

In some instances, the annular groove '7 may be dis pensed with and the pouring spout 8 extend directly out from the collar 6. This embodiment is, particularly but not exclusively, useful when the pouring neck either has no outwardly extending annular lip or flange 3 or only very narrow flange. The pouring member will neverthelcss be held securely in its operative position around the top of the pouring neck. It will be understood by those skilled in the art that still other modifications may be made within the scope of the appended claims.

What I claim and desire to secure by Letters Patent is:
