Description

Closure for a container, in particular beverage bottle, and container with such a closure

Description;

The invention relates to a closure for a container, in particular beverage bottle, with a lid and an attached on the cover Erstöffnungsgarantie. Furthermore, the invention relates to a container, in particular a beverage bottle, with such a closure.

Containers (packaging) for a wide variety of products are provided with a closure, which has a so-called Erstöffnungsgarantie. The Erstöffnungsgarantie is a lid of the closure associated element indicating to the consumer, whether the container or its closure has been previously opened before. The Erstöffnungsgarantie is therefore designed so that it is necessarily destroyed when you first open the shutter. Of particular importance is the first-opening guarantee for containers for foodstuffs such as beverage bottles. It indicates to the consumer that he is acquiring a fully filled container and that the contents are not contaminated by foreign matter. The latter has in connection with the recurrent series of attacks on certain products of certain manufacturers or distribution chains of particular importance.

For beverage bottles different first-opening guarantees are known. For example, it is known in glass bottles with aluminum lid, to provide the lid with a paper band, which is destroyed when first opened. Furthermore, it is known to provide a maintenance of the lid arranged ring on aluminum or on plastic lids, which is connected in a first variant via perforation webs with the lid. The perforation webs tear when screwing the lid, so that the ring is detached. In another variant, the ring itself is formed from a plurality of ring segments which are interconnected via perforation webs. The individual ring segments are connected via film hinges with the lid. When the lid is screwed on, the perforation webs break and the ring breaks up into the individual ring segments. Furthermore, so-called crown corks are known. These are deformed when opening by means of a bottle lifter so that they can not bend back to the original position and so for the Consumer is recognizable that the bottle cap has already been opened. When crown cap so the lid is also the first opening guarantee. However, the crown corks have the disadvantage that they open at very clever open only elastic, imperceptible plastic, deform, so that the bottle provided with the bottle cap can be closed again so that this remains unnoticed by subsequent consumers. If it is deformed as intended, it can no longer reasonably, especially no longer sealing, close.

Furthermore, so-called ring-pull closures are known. These have a closure cap - usually made of aluminum - and an opening ring connected by a cap tab. When opening by means of the opening ring tears the cap along the intended tear lines. The closure is destroyed, thus ensuring the first-opening guarantee. However, a reclosability of the container is impossible and the closure must be disposed of directly by the consumer. Since when tearing open sharp burrs on the cap, this carries the risk of injury.

For attaching the closure to the filled bottle at the bottler different methods are known.

A first method is the so-called roll-on method. This method can only be used in connection with glass bottles. The closure must therefore necessarily made of another material, namely plastic or

Aluminum, so that a mix of two materials is produced, which makes recycling difficult. A first-hole guaranty made of aluminum leaves sharp-edged ridges, which additionally increase the risk of injury to the consumer. The separate attachment of a glued

Paper banderole as a first-opening guarantee not only has the ecological

Disadvantage of an additional, third material and an additional

Process step in the attachment, but also carries the risk of unintentional destruction of the paper band during storage or transport. Also, the banderole can easily be vandalized by third parties, without the bottle was actually opened.

Furthermore, it is known plastic closures on the beverage bottle unscrew or blow up. This can be used for both glass and plastic bottles. Such closures have the tamper-evident warranty set forth above with a plastic ring integral with the closure. After opening the cap for the first time, the plastic ring will remain completely on the bottle or on the lid, depending on the type of opening guaranty. In the case of the retention of the plastic ring on the bottle, especially in reusable systems, a removal of the ring from the bottle must be done, which means an additional expense for the consumer or the resuming distributor. In the case of the whereabouts of the closure results in the consumer the disadvantage of a blatant obstruction of the reclosure of the bottle after a partial emptying due to the detached plastic ring. Both variants have in the production process in the filling system in the case of screwing the closure has the disadvantage that the screwing is a relatively complicated and time-consuming manufacturing process compared to bouncing or Ro I-on process.

Proceeding from this, the invention is based on the problem, a closure for a container, in particular a beverage bottle of the type mentioned in such a way that the closure can attach in a similar simple manner as a crown cap by bouncing on the container, yet sealing in contrast to the crown cap resealable and has a first-opening guarantee.

To solve this problem, the closure according to the invention is characterized in that the lid, in particular articulated, is connected to a ring which is captively connected to the container.

In contrast to the bottle cap, the object is thus closed in the closure according to the invention between closing the bottle by the actual lid and the Erstöffnungsgarantie. The ring is permanently connected to the example beverage bottle and remains even after opening the lid to her. When opening the lid for the first time, the first opening guarantee is destroyed as intended. In this case, then the lid and the ring, in particular articulated, connected to each other, so that the lid can remain connected after opening with the ring and thereby not lost. The consumer has the lid back to hand, to him again after a partial emptying close. Of course, the articulated connection, as well as the Erstöffnungsgarantie, but also be destroyed for certain applications when opening. This is important, for example, in the gastronomy sector, where the lid is usually completely removed from the bottle after it has been opened for the first time. Optionally, the Erstöffnungsgarantie itself may be the connection between the ring and cover.

Preferably, the lid and the ring are hinged together by means of a film hinge. In this way, according to a structural embodiment of the invention, the lid and the ring together with the Erstöffnungsgarantie in a particularly simple manner in one piece as a plastic injection molded part. This minimizes the manufacturing costs. Of course, it is also possible to form the lid and the ring in two parts and to manufacture separately, so that the lid and ring are subsequently connected together.

According to a structural embodiment of the invention, the lid is associated with an opening aid. At the opening aid, the lid can be easily detected by the consumer and so the lid can be opened in a simple manner. If such an opening aid is present, advantageously the first opening guarantee can be permanently connected to the opening aid. This ensures a direct application of force forces when first opened by the consumer in the Erstöffnungsgarantie so that it can be destroyed with relatively little effort by the consumer. Preferably, the Erstöffnungsgarantie engages in a recess on the opening aid and is connected by means of a suitable security element undetachable with the opening aid. Alternatively, however, separate recordings for the Erstöffnungsgarantie be provided.

The above description is essentially based on the fact that the Erstöffnungsgarantie attached to the ring and is permanently connected to the lid. Of course, it is also possible to attach the Erstöffnungsgarantie, in particular articulated, the lid and assign the recordings for attaching the Erstöffnungsgarantie the ring to the ring.

To continue destroying the opening guaranty upon first opening To facilitate, the Erstöffnungsgarantie may be provided with a weakening, via which it is connected to the lid or the ring.

The container according to the invention, in particular beverage bottle, is designed to solve the problem mentioned above with a closure according to the invention.

The invention will be explained in more detail with reference to embodiments shown in the drawing.

All closure variants shown in the drawing have in common that they have a cover 10 and a ring 11 arranged below a thickening at the mouth of the beverage bottle. The cover 10 and the ring 11 are articulated, in the present case by means of a film hinge 12, connected to each other. Further, the lid 10 is an opening aid in

Form of a protruding from the cover web 13 is arranged, at which the consumer can cover the lid to open the same. On the ring 11 a Erstöffnungsgarantie 14 is also hinged by means of a film hinge 15. The opening guarantee 14 has at its end opposite the film hinge 15 a barb 16, which engages in a corresponding recess 17 on the web 13. The recess 17 and the barbs 16 are formed so that, although it is possible to introduce the Erstöffnungsgarantie 14 with its barb-side end in the recess 17; but it is impossible to extract the Erstöffnungsgarantie 14 non-destructive again. Furthermore, the first-opening guarantee 14 has one in the present case in the Weakening arranged adjacent to the film hinge 15, which in the embodiment according to FIGS. 1 to 3 are perforation-like recesses 18. Furthermore, at the tamper-evident guarantee 14, a projecting web 19 extending transversely over the entire width of the tamper-evident guarantee 14 is provided.

Furthermore, all closures shown in common that the ring 11 has a plurality of circular segment-like stiffeners 20, which are connected by expansion elements 21 of lesser rigidity than the stiffeners 20 together. For reasons of strength, the film hinges 12 and 15 are each attached to one of the stiffeners 20 of the ring 11.

The closure described so far is manufactured in one piece as a plastic injection molded part. Subsequently, the lid 10 and the ring 11 are folded on the film hinge 12, wherein the

Erstöffnungsgarantie 14 folded on the film hinge 15 in the direction of the lid 10 and is inserted into the recess 17 on the web 13. The fully assembled functional position is shown in FIG. The extent prepared shutter can now be filled in the bottling plant

Beverage bottle bounced up. In this case, the ring 1 1 to the

Expansion elements 21 expanded and slips over a in the

Mouth area of the beverage bottle usually existing

Thickening, without, however, that it can be deducted by a consumer again.

If a consumer wants to open the beverage bottle, he grasps the lid 10 on the web 13 and pulls it upwards away from the ring 11. The weakening in the form of the perforation-like recesses 18 breaks and thereby destroys the opening guarantee 14. The beverage bottle is opened and the contents can be removed. To reclosure, the consumer simply pushes the lid 10 back onto the mouth of the bottle and the bottle is closed again, which, however, is visible to third parties due to the destroyed first opening guarantee 14.

The closure of FIG. 3 is slightly modified from the closure of FIG. 1 and 2, in the region of weakening. This is here as a between the barb 16 and the film hinge 15 arranged Strip 22, which has a lower strength than the film hinge 15 is formed.

The embodiments according to FIGS. 4 and 5 differ from the embodiments according to FIGS. 1 to 3 in that two

Erstöffnungsgarantien14 are provided, which in separate shots

23 are inserted at the ring 11. In the embodiment of FIG. 4, the Erstöffnungsgarantien 14 adjacent to the web 13 are arranged in a V-shaped position to each other, while in the embodiment of FIG. 5, the receptacles 23 are positioned laterally in diametrically opposite position and about 90 ° offset to the web 13.

The embodiment of FIG. 6 differs from the aforementioned embodiments by a different design of

Strain elements 24 on the ring 11. While the expansion elements 21 are formed in the above-described embodiments, approximately arc-shaped, with the belly of the bow facing outward, the

Strain elements 24 in the embodiment of FIG. 6 V-shaped, with an outwardly pointing tip.

The embodiment of FIG. 7 has at the bottom of the lid 10, the web 13 as an opening aid. The Erstöffnungsgarantie 14 is here U-shaped guided around the web 13 without being firmly connected to it, so, in contrast to the above Äusführungsbeispielen, assigned to the lid 10 and not the ring 11. Accordingly, a receptacle 25 for the Erstöffnungsgarantie 14 associated with the ring 11.

The embodiment according to FIG. 8 differs with respect to its expansion elements 26 from the exemplary embodiments explained above. The expansion elements 26 are formed here with an offset in Z-shaped form.

In this case, starting from one of the stiffeners 20, initially an outer segment 27 is provided, which terminates flush with the outer circumference of the stiffening 20 and has approximately half the thickness or less of the stiffening 20. To the outer segment includes a step 28, which is directed radially inward in the present case, but also below can run at an angle to the radial. The step 28 is adjoined by an inner segment 29, which, with respect to its inner circumference, is aligned with the inner circumference of the adjacent stiffener 20 and in turn has approximately half the thickness or less of the stiffening 20.

In the embodiment of FIG. 9 expansion elements of three adjacent arches 35 are provided with inwardly directed bellies. Where two adjacent arcs 35 adjoin one another, they form a point 30.

FIGS. 10 to 13 show different variants for weakening the tamper-evident guarantee 14. In the embodiment according to FIG. 10, the weakening is in the form of a transverse notch 31 extending over the entire width of the tamper-evident guarantee 14. In the embodiment according to FIG. 11 elongated perforations 32 are provided, while the embodiment according to FIG.

12 has round perforations 33. The embodiment of FIG.

13 corresponds to the embodiments of FIGS. 1 and 2. If necessary, the perforation holes 32, 33 need not be completely passed through the Erstöffnungsgarantie 14. Wells are sufficient analogous to the embodiment of FIGS. 1 and 2.

Fig. 14 shows once again how the Erstöffnungsgarantie 14 is inserted into the recess 17 on the web 13. In the embodiment of FIG. 15, a spherical thickening 34 is present instead of the barb 16.

The lid 10 has on its inside inwardly directed lips (not shown), which engage behind in a conventional manner a bead on the bottle mouth. The closure can be like a bottle cap in a simple way to the container, so the beverage bottle, put on, the lid (10) is resealable. Thus, the closure according to the invention thus combines the advantages of the crown cork with the advantages of plastic closures for screwing. In this case, the closure according to the invention can be integrated in a simple manner in the conventional manufacturing process in the bottling plant, since the closure can be aufgeprellt as a crown cap. Furthermore, the closure for all types of bottles, so regardless of whether the bottle is made of plastic or glass, can be used. Reference number list
