Description

 CLOSURE FOR A CONTAINER, IN PARTICULAR A BEVERAGE BOTTLE

Description:

The invention relates to a closure for a container, in particular beverage bottle, with a lid, hingedly connected to the lid hinge strap and a 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 opening guarantee is therefore designed so that it is necessarily destroyed when the shutter is first opened. 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 the contents are not contaminated by foreign matter. The latter has special significance in connection with regularly occurring stop series for certain products of specific manufacturers or distribution chains.

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 on aluminum or plastic caps a arranged below the lid ring, which is connected in a first variant via perforated 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 tear 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 do not more bend back to the original position and is thus recognizable to the consumer 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 deform with very skillful opening only elastic, imperceptibly plastic, 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 cap - usually made of aluminum - and connected by a cap tab opening ring. 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 sharp edges create burrs on the cap during tearing, this entails 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 be chosen from a different 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 application of a taped paper wrapper as Erstöffnungsgarantie 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 accidental destruction of the paper wrapper during storage or transport. Also, the banderole can easily be vandalized by a third party, without the bottle was actually opened. Furthermore, it is known to unscrew plastic caps on the beverage bottle 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 beverage industry. 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 roll-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 easily by bouncing on the container, yet resealable and has a re-seal opening.

To solve this problem, the closure according to the invention is characterized in that the hinge strap and the opening guarantee are connected by means of gluing or sealing with the container.

In this case, the bond or seal directly between the hinge strap and the Erstöffnungsgarantie one hand and the container on the other hand or indirectly, for example by a wrapped around the container and the hinge strap and Erstöffnungsgarantie around and bonded banderole or by a shell made of plastic, on the bottleneck or the bottle is shrunk or stretched, done. The actual closure of the container takes place through the lid, while a separate opening guarantee is provided. Due to the inventive attachment of the lid to the container on the Schamierlasche the lid remains even after the first opening the container and can be used in a simple and clean way again for closing the container. The first opening of the lid is recognizable but the first opening warranty, as this is destroyed as intended when first opened.

Preferably, the Erstöffnungsgarantie is hingedly connected to the lid. The closure can thus be produced as a flat part, for example as a plastic injection molded part. When attaching the closure to the container hinge strap and Erstöffnungsgarantie be folded against the container and attached here in the manner described above. The articulated connection of the hinge strap or the Erstöffnungsgarantie on the one hand with the lid on the other hand preferably takes place via a film hinge, since this can be particularly easy to produce in a closure as a plastic injection molded part.

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 arranged in the vicinity of the opening aid. This ensures a direct application of force to the forces when first opened by the consumer in the Erstöffnungsgarantie so that it can be destroyed with relatively little effort by the consumer. Preferably, a first opening guarantee is arranged on each side of the opening aid.

In order to further facilitate the destruction of the first opening guarantee upon first opening, the first opening guarantee may be provided with a weakening by which it is connected to the lid.

In order to obtain the largest possible adhesive or sealing surface, the hinge flap and / or the opening guarantee is provided with a broadening. By the resulting larger adhesive or sealing surface of the grip between the container on the one hand and the hinge plate and / or the Erstöffnungsgarantie on the other hand is improved.

The container according to the invention, in particular beverage bottle, is to solve the above-mentioned problem with an inventive Formed closure.

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

All illustrated embodiments have in common that on a cover 20, a hinge plate 21 and at least one, specifically two

Erstöffnungsgarantien 22, 23 are attached. These are each about one

Film hinge 24, 25 or 26 integrally connected to the lid 20.

Furthermore, an opening aid 27 is integrally formed on the lid 20, at which the consumer detects the shutter to open the lid 20.

In the closure shown in Fig. 1 to 4 hinge tab 21 and opening aid 27 are arranged diametrically opposite one another on the cover 20. The Erstöffnungsgarantien 22, 23 are diametrically opposite and arranged at 90 ° to the hinge plate 21 and the opening aid 27 on the lid 20.

When attaching the closure described so far to a container, specifically at the mouth 28 of a beverage bottle, the lid 20 is bounced on the mouth 28. As shown in FIGS. 3 and 4, the cover 20 engages in a manner known per se an upper bead 29 at the mouth 28 with a circumferential lip 30. A ring-like seal 31 integrally formed on the cover bears against the mouth 28 in a sealing manner. Alternatively, a separate liner can be used as a seal.

When bouncing the lid 20 on the mouth 28, the hinge plate 21 and the two Erstöffnungsgarantien 22, 23 are folded at their hinges 24 ... 26 against the mouth 28. As can be seen in FIGS. 3 and 4, engage the hinge tab 21 and the Erstöffnungsgarantien 22, 23 in each case with an inwardly directed web 32 another, lying below the bead 29 bead 33. In this position, the hinge tab 21 and the Erstöffnungsgarantien 22, 23 secured to the mouth 28 by, for example, glued or sealed with the mouth 28. It is also possible, around the mouth 28, including the hinge tab 21 and the Erstöffnungsgarantien 22, 23, to put a band and stick or seal with the mouth 28 and so to provide an indirect connection.

When first opened the consumer takes the lid 20 on the opening aid 27 and pulls the lid 20 upwards away from the mouth 28. As a result, the lid 20 is opened around the film hinge 24 of the hinge plate 21, the Erstöffnungsgarantien 22, 23 are destroyed. For this purpose, the Erstöffnungsgarantien 22, 23 associated with weakenings, which in the embodiment of FIGS. 1 and 2, the respective film hinges 25, 26 themselves.

Also in a second embodiment shown in Figs. 5 and 6, the weakenings are the film hinges 25, 26 themselves. However, from the embodiment described above, this shutter differs in that the first opening guarantees 22, 23 are arranged in the longitudinal direction and on both sides of the opening aid 27 are.

In the embodiment according to FIG. 7, separate weakenings in the form of two oblong holes 34 arranged next to one another are provided on the first opening guarantees 22, 23. In the embodiment of FIG. 8, the weakening is given by a notch 35, while the weakening in the embodiment of FIG. 9 in the form of perforation holes 36 is present. In the embodiment according to FIG. 11, elongate cut-outs are provided as weakening. The embodiment of FIG. 12 shows a further positioning for the Erstöffnungsgarantien 22, 23. Although these are now also arranged on both sides of the opening aid 27, but they point in the radial direction of the lid 20. It also behaves in the embodiment of FIG. 13, which, however, has two separate hinge straps 21 on the side opposite the opening aid 27 side of the lid 20.

In the embodiment according to FIG. 14, the first-opening guarantees 22, 23 are arranged in the immediate vicinity of the hinge lug 21 and again point in the radial direction of the cover 20.

In the embodiments of FIGS. 15 to 18, the hinge tab 21 and / or the Erstöffnungsgarantien 22, 23 are provided with spacers 38 and 39, which provide a larger adhesive or sealing surface for the hinge plate 21 and the Erstöffnungsgarantien 22, 23. As a result, the hold of the hinge tab 21 or the Erstöffnungsgarantien 22, 23 is improved at the mouth 28. In the embodiment according to FIG. 15, the hinge lug is T-shaped, so that the widening 38 extends on both sides away from the hinge lug 21. In contrast, the Erstöffnungsgarantien 22, 23 are L-shaped with each other directed widenings 39th

In the embodiment of FIG. 16, only the Erstöffnungsgarantien 22, 23 are provided with a common broadening 39, so that the Erstöffnungsgarantien 22, 23 with the widening 39 form a U. In the embodiment of FIG. 17, the Erstöffnungsgarantien 22, 23, however, T-shaped, analogous to the hinge plate 21 in the embodiment of FIG. 15. In the embodiment of FIG. 18, two hinge plates 21 with two Erstöffnungsgarantien 22, 23 are provided. In each case one hinge tab 21 is connected to an adjacent first opening guaranty 22, 23 via a common widening 40.

Of course, the invention is not limited to the embodiments described above. Rather, other variants, in particular mixed forms between the embodiments described above are conceivable. LIST OF REFERENCES
