Pouring spout for mounting on a container

Abstract: According to the invention a pouring spout for mounting on a container's neck can be configured as a spout (4,14) placed in the container's (1,13) neck (3,15), which spout goes on the inside of the neck so that possible drops of liquid will be collected inside the neck (3,13). Drops of liquid running on the outside of the container are hereby avoided and at the same time it is achieved that the container can pour in all directions since the edge (8) of the pouring spout (4,14) extends uniformly around the container's neck.

Description: The known technique The invention concerns a pouring spout for mounting on a container such as a bottle, preferably a wine bottle, by insertion in the bottleneck, said pouring spout forming a channel between its outer side and the inner side of the bottleneck in order to collect possible drops, when the bottle is raised upright after pouring, which pouring spout has a cylindrical lower part and an outwardly curved upper part extending above the top of the bottleneck, when in mounted position, said upper part being configured with three or more ribs, which, when the pouring spout is mounted, extend between the outside of the upper part of the pouring spout and the inner edge of the bottleneck, and with sealing means between the bottom of the lower part and the inner wall of the bottleneck. When pouring liquids out of a container, such as a thermos flask or bottle, liquid will often be left remaining on the spout which, when the container is raised, possibly collects in drop form and drips down or runs down the container. Many attempts have been made to eliminate this disadvantage, especially in the form of diverse configurations of separate pouring spouts. Common to the known pouring spouts is the problem of adapting to the inner diameter of the various outflow spouts, as these exist in several sizes. If, thus, the outflow spout is too large, the pouring spout will easily fall out during pouring, and if the outflow spout is too small, the pouring spout cannot be pressed into the outflow spout. From FR-A-505 417, in which the preamble of claim 1 is based, a pouring spout is known, which is provided with an elastic rubber ring around that part of the pouring spout which extends down into the outflow spout and presses against the outflow spout so that the pouring spout does not fall out. However, the precondition for this is that the inner diameter of the outflow spout in all essentials fits the outer diameter of the rubber ring. Since, as mentioned, there are variations in e.g. the inner diameters of outflow spouts, it is a problem to make the pouring spout fit securely in a variation of bottles. The object of the invention It is the object of the invention to overcome these drawbacks and disadvantages of the known pouring spouts, and according to the invention this is achieved in that the sealing means in the lower part comprises an annular flange or lip, which lies up against the inner wall of the bottleneck. in this surprisingly simple manner, it is ensured that the pouring spout can adapt and be used in outflow spouts within a relatively large diameter interval, as the outer side of the flange will bend and thus adapt to the size of the outflow spout. It is hereby ensured partly that the pouring spout remains in the outflow spout, and partly that it always fits tightly against the outflow spout. The pouring spout can be pressed down into and pulled out of the outflow spout easily, as the flange can be bent relatively easily in its periferal area. The drawing In the following, example embodiments of a pouring spout according to the invention will be described in more detail with reference to the drawing, where fig. 1 shows an example of a pouring spout partly in section placed on a container such as a thermos flask, fig. 2-4 show an example of a pouring spout for bottles, and fig. 5 shows a partly sectional view of a pouring spout placed on a bottle. Description of the example embodiments In fig. 1 there is shown a first embodiment of a pouring spout for use on a thermos flask 1 or similar container. The container does not have a handle, and its own pouring spout 3 is therefore configured as an annular collar which ends in an edge. Without pouring spout, this container will have a tendency to drip liquid from the outflow spout. To avoid this, a pouring spout 4 according to the invention is mounted, said pouring spout being configured with a lower cylindrical collar 10 which rests against the top of the flask 1 with outflow hole 2 possibly with thread for a not-shown closing stopper. On the collar 10 there is configured an annular groove or seating 5 for a sealing ring 6 which lies in a tightening manner up against the inside of the outflow edge 3 of the flask. The upper part of the outflow spout 4 is configured as an outwardly-curving collar 7 which extends a small distance up over the edge 3 of the flask, and substantially to the same outward extent as this edge. The collar 7 ends in an edge 8 which is suitably sharp. This is to minimise the risk of adherence to this edge portion after pouring out. The way in which this pouring spout functions is that it can be mounted on any flask with a normal, upwardly-extending outflow funnel 3. When the stopper is removed from the outflow opening 2, upon tipping of the edge liquid will run down over the outflow part 7, over the edge 8 and further. When the pouring ceases, the liquid in the outflow spout 7 will run back into the container, possibly leaving a small amount of liquid in the edge zone 8. This liquid will, however, run down in the gap which is formed between the outside of the outflow part 7 and the inside of the mouth 3 of the flask, and is collected there due to the sealing ring 6. The liquid thus remains in the flask and will in no way be able to soil the outside of the flask, which can therefore always be held clean and free from deposits of tea, coffee and the like. The pouring spout does not interfere with the remaining functions and working mode of the flask in any way whatsoever, and this can thus be handled and used in the completely normal manner. The pouring spout can be made either of metal or plastic or a combination hereof. A further embodiment will now be described with reference to figs. 2-5. This pouring spout 14 is dimensioned in such a way that it can be inserted in the neck of a bottle, e.g. a wine bottle as illustrated in fig. 5. The pouring spout comprises a lower cylindrical part 10, the diameter of which is smaller than that of the bottleneck, so that it forms an annular gap between the lower part 10 and the bottle 13, as shown in fig. 5. At the lower end there is configured a seal 11, e.g. in the form of an integrated, annular elastic flap or lip, which is suitably elastic to be able to create tightness, and to function as a securing flange for the pouring spout 14 when this is pressed down into the neck of the bottle 13. As indicated in fig. 5, this flange 11 will secure the pouring spout in the bottle, and it will require an extra force to remove it from the bottle, in that the flange 11 will function as a barb. Therefore, the pouring spout will not be able to fall out of its own accord when being used. At the top, the pouring spout expands into an outwardly-curved collar 7 which ends in a sharp edge 8. In order to control the central positioning of the pouring spout in the bottleneck, projections or ribs 12 are provided on the outer side of the collar 7, as shown in fig. 5. These ribs will lie up against the upper edge 15 of the bottle and ensure the central positioning of the pouring spout. For this purpose, at least three ribs 12 placed in an equidistant manner are required. The pouring spout with this embodiment will function in the same way as that described earlier, i.e. it will ensure an even outflow and minimum drip from the outflow groove. Possible drip will remain inside the bottleneck and be accumulated in the collection groove, so that the outside of the bottle is kept free of drips and herewith discolouring. This pouring spout 14 also functions in all directions, and thus the bottle does not need to be orientated before pouring out. This pouring spout will similarly be able to be produced in metal or plastic material or a combination hereof. Moreover, it has no unfortunate influence on the function of the bottle that it will otherwise easily be able to be equipped with a loose stopper, so that the pouring spout can also function as a closing stopper with the view to later pouring out.
