Abstract

The invention relates to a pouring device which can be placed, by an interior bearing surface (4), on the edge of a pouring orifice (5) of a bottle-like receptacle (1). Said pouring device has an axial bore hole (3) for the liquid to flow through, and fastening elements enclosing the outer wall of the pouring orifice, as well as a trumpet-shaped wall (8) extending the bore hole (3) from the interior bearing surface (4) outwards and that has a circumferential pouring edge forming a pull-off edge (7). The pouring device has an aperture angle of 60° - 120°. Furthermore, the fastening elements enclosing the outer wall of the receptacle comprise elastic brackets (10) with stop pins (11), and a highly elastic sealing element (6) is fitted between the pouring orifice and the bearing surface (4). The invention thus provides a pouring device which can be easily placed on the neck of the receptacle and is held there securely. It is characterized by substantially improved pouring properties.

Description

Spout

The invention relates to a spout for bottle-like containers according to the preamble of claim 1.

Such a spout is known for example from DE 88 14 921 U1. Other pourers have in common that they consist of a plug-like structure which has a hole with ig, in which, depending on the intended use, a straight or slightly curved tube with a constant diameter or narrowing upwards towards the pouring edge is arranged. The aeration of the bottle required for even pouring out may take place through a separate bore or a separate pipe.

The fastening and sealing takes place regularly in the upper, approximately cylindrically shaped part of the bottle-like container. Tapered corks and one-piece base bodies made of plastic with radially circumferential ring ribs have found widespread use here.

The pourers of the type mentioned at the outset, and here in particular pourers that can be placed alternately on wine bottles, have significant disadvantages:

A common disadvantage is the casting geometry. This is because in the casting process, a relatively strongly bundled jet of liquid is generated, producing a relatively long casting parabola. With a larger liquid throughput, the liquid jet usually begins to pulsate strongly, which counteracts targeted delivery. An effective control of the casting process can essentially only be achieved through large, rapid changes. Changes in the angle of inclination of the bottle take place, a fine dosing is not always possible, especially while avoiding any dripping.

Another major disadvantage is the relatively low liquid throughput. The use of such spouts, in particular for serving wine or comparable beverages in quantities customary for consumption, is therefore only unsatisfactorily possible.

A further disadvantage lies in the handling, in particular in the large amount of force that is required in order to fasten the spout to the pouring opening or in the inadequate seal with the result that liquid drips uncontrollably.

Starting from this prior art, the invention has for its object to provide a spout that increases the pouring comfort, can be easily placed on the container neck and holds securely.

This object is achieved with the characterizing features of claim 1.

The advantages achieved with the invention consist in particular in the substantial improvement of the pouring properties. By moving the pouring opening forward from the pouring opening of the bottle-like container and expanding it, a geometry is generated which further surrounds or surrounds the parabolic liquid flow which arises during pouring tracking provides a sliding surface. Surprisingly, it has been shown that this produces a substantially shorter and thus more controllable pourable parabola, which changes only slightly when the liquid throughput is reduced. a bundled jet of liquid is retained despite the widening wall. With the pourer according to the invention, even inexperienced persons can be finely dosed, drip-free and also elegantly poured out, in particular of beverages.

As a result of the resilient tabs, the spout can be securely and sealingly placed on a bottle-like container corresponding to the design of the spout, even by inexperienced persons, with deviations from a manufacturing-related press offset or from dimensional tolerances being compensated for by the elastically resilient elements .

According to an advantageous embodiment, the pouring spout has a cover which can be placed on the tear-off edge or the inner wall below the tear-off edge and which closes the opening and, in a further embodiment, is advantageously perforated to enable air exchange.

It is advantageous here that additional functions can also be performed with a spout according to the invention. Since the relatively large pouring opening tends to receive multiple dust or other foreign bodies, in particular in the room air, it is expedient to cover the opening, which can be breathable.

In a further embodiment of the subject matter of the invention, a sieve structure is provided between the seal that can be placed on the edge of the pouring opening of the bottle-like container and the contact surface of the body, spanning the opening. It is advantageous here that, in a further additional function, foreign bodies can be screened out of the liquid, with a simple retrofitting of the spout according to the invention being made possible.

Several embodiments of the device according to the invention are described below by way of example with reference to the drawing: FIG. 1 shows a spout according to the invention with a lid, in an embodiment for a normal wine bottle, in a side view FIG. 2 shows a spout according to FIG. 1 without a lid in section FIG 3 - a pouring spout according to FIG. 2 when pouring out smaller quantities FIG. 4 - a pouring spout according to FIG. 2 when pouring out larger quantities FIG. 5 - a pouring spout according to FIG. 2 at an inclination in which the liquid flow is interrupted

Fig. 6 - a spout according to Fig. 2 in an inclination, in which liquid residues flow back Fig. 7 - a spout according to Fig. 2 with modified inner wall and an inserted sieve in section

Fig. 8 - a spout according to FIG. 2 with a reduced

Pour opening and undercut Fig. 9 - a spout in section with a two-part hollow body.

The spout according to the invention shown in FIGS. 1 and 2 consists of a hollow body 2 which can be placed on a wine bottle 1. The hollow body 2 has an axially arranged one Bore 3 for passing the liquid, here wine, and lies with the bearing surface 4 on the edge of the pouring opening 5 of the wine bottle 1. For sealing, a sealing element 6, which acts in a highly elastic manner in the direction of action W, is inserted between the contact surface 4 and the edge of the pouring opening 5. Continuing the axial bore 3 upwards, the wall 8 which slopes outward toward the tear-off edge 7 is arranged. The wall 8 and the outer wall 9 form an acute angle S, producing the tear-off edge 7. The outer wall 9 is chosen such that the outer diameter of the body 2 decreases downwards. It is important here that a groove-like undercut is provided directly below the tear-off edge 7. Here the undercut is smoothly inserted into the outer contour of the spout. Below the support surface 4, eight elastic, spring-loaded tabs 10 are arranged so that the hollow body 2 is extended downward. At the lower edge of the tabs 10, locking cams 11 are provided, which hold the spout on the edge of the pouring opening 5 of the wine bottle 1. The locking cams 11 are designed so that they are pushed apart when pushed onto the bottle neck by the lower bevels 12, slide over the thickening of the bottle and spring together below it. The material strengths of the tabs 10 are selected in the area above the locking cams 11 so that a sufficiently large spring action is generated and the upward forces occurring in the direction of action W on the sealing element 6 are overcome and the spout is thus held securely . To remove the pouring spout, it is simply pulled off the holding wine bottle 1 upwards. Here, the tabs 10 are pushed apart again by an upper bevel 14, whereby the spout is released upwards. The lower slopes 12 are functionally related with a long cut and thus with a small flank angle, here about 20 ° to the body axis, and the upper slopes 14 with a flank angle of about 45 ° to the body axis. Thus, the spout can be pushed on relatively easily, which means with little effort. About the 45 ° slope, the spout is self-locking under the thickening 13 of the wine bottle against the resilient sealing element 6. The self-locking effect of the upper slope 14 is, however, only so great that the spout can be pulled off with a slightly increased effort.

The diameter of the axial bore 3 corresponds at most to the inside width of the neck of the wine bottle 1. This does not reduce the possible flow through the spout. The opening angle L is 90 °. It has been shown that this angle is particularly suitable for combining the other effects according to the invention.

If necessary, the spout can be closed with a lid 15. In a further embodiment, a cover is provided which is perforated at the top, the openings being advantageously spanned with a breathable flow. Such a lid prevents, for example, if a red wine has been opened to breathe and is to be kept in front of foreign bodies from entering the bottle.

The casting process which is the same in all the configurations according to the invention is described in more detail with reference to FIGS. 3 to 6. For pouring out, the wine bottle 1 is inclined until the liquid begins to flow through the pouring opening 5 of the bottle 1 and through the axial bore 3 of the pourer over the inclined wall 8, describing a pouring parabola P. If the bottle 1 is tilted more, the liquid flow increases, but continues to describe the parabola P, as shown in FIG. 4. The decisive advantage lies in the fact that the position of the bottle 1 during metered pouring, not following a changing pouring parabola, must be adjusted. In connection with the larger axial bore 3 there is the possibility of dosing the liquid jet over a wide range with constant pouring comfort. When the pouring process is interrupted, the liquid flow is interrupted at the transition 16, as shown in FIG. 5, which means that the liquid level drops behind this edge, the liquid residue on the inclined wall 8 at that moment remaining on the pouring edge 7 clumps into a drop 17 which, as shown in FIG. 6, flows back into the interior when the bottle 1 is further erected or remains on the inner wall.

The spout shown in FIG. 7 corresponds in its essential characteristics to FIGS. 1 and 2. Correspondences are not explained again. In order to create a possibility of filtering out foreign bodies such as cork residues from the wine, a sieve structure 18, which is shaped in a conical shape and has a flange-like extension, is additionally inserted between the bearing surface 4 and the sealing element 6. Since the annular sealing element 6 seals laterally and at the bottom, an unwanted wine leakage is excluded. Retrofitting or replacement of the screen structure is possible at any time due to the simple arrangement. The conical design enables a better air supply and thus improves the flow behavior of the wine. In a further embodiment, the inclined wall 8 is slightly curved here and is shown merging into the vertical wall of the axial bore 3. With the inclination of the wall 8 according to the invention, such a geometry also corresponds to the concept of the invention. The design the transition 15 as a curve can slightly improve the smooth flow of wine.

The spout shown in FIG. 8 also corresponds in its essential characteristics to FIGS. 1 and 2. Correspondences will not be explained again. The pouring opening of the spout enclosed by the tear-off edge 7 is reduced to a minimum. In order to ensure proper functioning according to the invention, an undercut 19 is provided here, which replaces the undercut of the tear-off edge with the same effect. An embodiment corresponding to FIG. 8 makes it possible to change and reduce the proportions of the hollow body 2 in such a way that a space-saving shape which may take less getting used to can be derived and created. Manufacturing-related savings are also advantageous.

The spout shown in FIG. 9 has a two-part hollow body 2. The upper part 20 lies with its support surface 4 on the sealing element 6, which in turn rests on the pouring opening 5 of a bottle. According to the invention, the axial bore 3 is extended into an inclined wall 8 with a tear-off edge 7. The undercut 19 undercuts the tear-off edge 7 on the outside. The upper part 20 is fastened to the outer bottle wall surrounding the pouring opening 5 with the lower part 21, which is anchored in the annular groove 22 of the upper part 20. The advantage of this embodiment lies in the large number of possible material combinations, the material of the upper part 20 not having to have the special properties with regard to the spring action as the material of the lower part 21. It is expedient, depending on the configuration, to produce the spout according to the invention in one or two pieces from plastic using injection molding technology and to insert a cut sealing element so that it can be replaced. The spout can also be machined in a one-off production, whereby all permissible and suitable materials are conceivable. It is also conceivable to provide the lower part of the spout with an internal thread.
