Description

PURPOSE OF THE INVENTION

The present invention relates to a spout, which is preferably to be attached to glass bottles. State of the art

Many foods are now packaged in eco-friendly returnable bottles. First and foremost here are milk in the well-known bottles with a capacity of one liter, but also fruit juices or syrups of any kind, which are often packed in glass bottles.

When pouring, for example, milk from a glass bottle, there is the fundamental problem that afterwards on the outside of the bottle always run one or more drops of droplets down. The bottle looks unsightly, is sticky, and most of the time, there is also a milk margin at the place where the bottle stands on the ground. In syrup or fruit juice, this disadvantage is even more serious: Such a bottle, which is usually in use for a long period of time, is on the outside closed ^¬ Lich so that you do not like to touch them. Of course, this problem has long been known and, accordingly, attempts have been made for decades to remedy the situation. By way of example, some prior art devices are cited which are intended to enable a drop-free and clean pouring of a liquid from a container without clucking or to show a certain manner of attachment to a container.

DE 1 837 444 U describes a closure, e.g. for milk bottles, which by means of a lip-like bead snaps on the neck of the bottle. Opposite the spout opening of the spherical cap-shaped lid, an air supply opening, not further described, is attached.

DE 101 60 362 AI discloses a cap for a glass bottle, which is fixed as a disposable part after filling the bottle and after opening serves as Ausgusshilfe. A ventilation opening to prevent gurgling during pouring is not shown. EP 1451076 Bl shows a comparatively complicated spout with Lufteinströmöff ^¬ voltages 70 (Fig. 1, 3, 7a-c) and various flat partition elements between air and liquid, see for example pos. 72 in Fig. 4 or pos. 100, 102 or 106 in Fig. 7a-7c. It is apparent from paragraphs [0049] to [0053] in conjunction with Tables A and B and FIG. 8b which efforts have been made here to ensure that the air can flow without liquid entering the airway.

DE 30 09 568 shows a closure with pouring opening for containers. When looking at Figure 1 it is noticeable that this corresponds to a spout for small glass bottles, which in particular contain coffee cream. A ventilation opening is not provided.

DE 197 35 696 AI discloses a Flaschenausgießer with V-shaped opening and a spout and a non-descript ventilation.

US 2 650 734 A discloses a spout for bottles (see in particular Fig. 2), which has an outlet opening 26 for the liquid and a ventilation opening 40 with a constriction 42. This constriction is intended to solve the fundamental problem that flows during the pouring liquid / milk through the air inlet opening, see. Sp. 4, lines 31-53. As a result, the spout is injection-technically very complicated, which is due to the production of the various channels 26, 24, 38 and 40 and 42.

DE 1 847 717 U is considered to be the closest prior art. Here, a one-piece bottle cap with spout and protective cap is disclosed, the five embodiments of which have the common feature that air inlet holes are formed, which penetrate the bottom of the spout and should also serve as return openings for milk. The orientations of the spout for the liquid and the air inlet holes are parallel to each other, which may be considered critical because, when pouring the milk, it may possibly shoot through the air inlet openings. The fundamental problem that not only air can penetrate through the air holes, but may leak liquid, is not addressed in this document at all.

Thus, various disadvantages are described, which are eliminated with the present invention. It is about constructing a spout that is absolutely easy to manufacture and with this simple design solves the problem that leaks through the necessary ventilation hole liquid. The vent should - unlike in all devices described above with ventilation option - penetrate the wall of the spout at any point. the solution of the problem

The above object is achieved by a spout with the features of claim 1. Further advantageous embodiments emerge from the features of the subclaims. Claim 11 has a method for producing a closed circumference of a ventilation duct to the object.

Fig. 2 shows a perspective view of the spout according to the invention when it is attached to the container;

FIG. 2a shows a side view of the spout according to the invention with a dust protection cap; FIG.

FIG. 1 shows a perspective view of the spout 3 according to the invention. In the container 5, of which only the upper part is shown, it is a II standard bottle for drinking milk. One recognizes the mouth region of the glass bottle and the upper edge of the bottle 10. The container 5 is provided with thread embossments 12, to which a closure lid (not shown) is screwed in the filling system, and provided with a fixing web 15. The spout 3 according to the invention is intended as a reusable part, which can be used again and again for drip-free pouring. After the purchase of a milk bottle, the closure cap is replaced by the pouring spout 3 according to the invention. A seal 40 is also shown which can act between the spout and the upper bottle rim 10, which will be discussed later.

With further reference to FIGS. 2 and 3, the spout 3 essentially consists of a cover part 19, in which a pouring opening 20 is located. At the top of the lid partly 19, a pouring spout 23 is provided in the pouring direction adjacent to the pouring opening 20. The pouring spout 23 has a relatively sharp tear-off edge 23a at which the flow of milk to be poured cleanly breaks off. On the underside 22 of the cover part 19, a jacket part 24 with an inner side 24a is provided on its outer circumference. At the bottom of the inner side 24a there are lugs 24b, which engage when screwing the spout 3 with the thread embossments 12 of the container 5 in engagement. Optionally, 24 retaining clips 27 can be arranged at the lower edge of the shell part, which snap-engage on the fixing web 15 of the container 5 (cf., FIG. 3a). The spout 3 according to the invention is thus attached to the container 5 via the lugs 24b and / or the retaining clips 27. Incidentally, the dust cap 60 is shown only in FIG. 2a, but should be provided on the finished product in order to protect the pouring opening 20 against the ingress of dust, foreign bodies, insects, etc.

Fig. 3 is a perspective view of the spout 3 seen from below, i. it shows the side facing the interior of the container 5 in the screwed-on state. One sees an annular region 30, whose bottom cooperates with the upper edge of the bottle 10 of the container 5. The spout 3 can be used without a seal as shown in Fig. 3; According to experience, the contact point between the bottom of the annular region 30 and the upper edge of the bottle 10 is liquid-tight. However, it is also possible to use a seal 40 (see FIG. 1) which is inserted into the annular region 30 of the spout 3. In this case, then sits just the seal 40 on the upper edge of the bottle 10. The seal 40 is a circumferentially closed annular flat gasket, which is inserted into the spout.

Alternatively, the seal 40 is a one-piece seal with the spout 3 which is sprayed in the annular area (similar to the rubberized seals in the jam lid jars) with the exception of a ventilation duct 25a / b and indicated in FIG. 3 by cross-hatching is. This alternative is preferable in terms of hygiene because no milk can accumulate between the seal and spout here. Of course, the spout and the seal are made of food grade plastic.

An essential element of the spout 3 according to the invention is the ventilation channel 25a / b, which consists of a first section 25a and a second section 25b. The first portion 25a is machined on the underside 22 of the lid portion 19 as shown, and the second portion 25b is provided on the inner side 24a of the skirt portion 24. The entire ventilation channel 25a / b is formed without undercut, whereby no slides are needed in the production tool in this area. Optionally, the first one Section 25a equipped with a Strömuhgslabyrinth 50. However, it is expressly pointed out that even without said flow labyrinth, it is ensured that only air actually flows through the ventilation channel 25a / b during pouring and does not, for example, inject milk to the outside.

The retaining clips 27 may serve to indicate to a user that the spout is cleanly screwed onto the mouth of the container 5 by engaging the fixation web 15 with a fine but audible click, cf. Fig. 3a. The perfect functioning of the spout 3 is evidenced by a series of prototypes made by 3D printing. The pouring spout 23 provides drip-free pouring, and it has been demonstrated that, during pouring, liquid never escapes through the venting channel 25a / b, whether the liquid is poured out smoothly or quickly. Even by shaking the container 5 during pouring, it is not possible to let the liquid escape through the ventilation channel 25a / b. Thus, by a simple construction in a most surprising way, it has been possible to solve the main problem, which is to prevent the escape of liquid through the ventilation duct. 2 shows a side view of the spout according to the invention with a dust cap 60. The dust cap 60 is preferably mounted on a spout on the spout and locked in place on the spout, as is known in the art. It is of course also provided with a pivoting dust cap (not shown) possible, which is used with their pivot pin in corresponding receptacles on the spout or clipped. Furthermore, a closure slide 70 (not shown) is intended to cover the pouring opening. However, from a hygiene point of view, the dust cap is preferable.
