Description

technical area

The The invention relates to a container closure according to The preamble of claim 1. The invention further relates a container closure system according to Preamble of claim 12.

State of technology

Plastic closures with tamper-evident or with an indicator of integrity is available in a wide variety. You're supposed to make sure the buyer has one in a bottle or another container bottled Product has the certainty that manipulates the product itself nothing and that he can thus use the product without hesitation. Therefore, must On the one hand, these backups and scoreboards ensure that the Lock not opened on the other hand, that he also does not leave the container for a short time has been removed. The first task is usually fulfilled by the fact that a guarantee strip secures the lid of the closure. So that Bottle opened first, the guarantee strip must be removed. For the second Task proposes the prior art, various solutions.

A solution is to close the bottleneck under the lid with a foil, which either removed by hand or by an appropriate Construction is punctured in the closure. Covering the bottle with the film makes the filling process more expensive. The removal of the film by hand is time consuming and appropriate undesirable. The special construction in the clasp makes it more expensive and expensive the closure and is therefore also suboptimal.

In another solution not only does the guarantee element secure the lid to its base but also at the same time the lower part opposite the bottleneck. A disadvantage This arrangement is that after the first opening of the bottle no more It can be determined if the closure at a later date removed from the bottle and the liquid in the bottle replaced has been.

presentation the invention

It It is an object of the invention to provide a container closure, which fixes the above problems.

These Task solves a container closure with the features of claim 1.

Of the invention Container closure points a lower part, an over a hinge axis with this connected upper part and at least an indicator of integrity, which in the first served Condition on a container irreversible during a rotational movement of the closure relative to the container destroyed becomes. Furthermore, there is an integrity guarantee element which in the first-closed state of the closure during a pivoting movement the upper part relative to the lower part about the hinge axis irreversible destroyed becomes. According to the invention the at least one integrity guarantee element is completely independent of at least one tamper-evident indicator.

Preferably the indicator is an integral part of the shell of the closure and the warranty element is a guarantee strip, which is completely torn away can be.

Of the invention Indicator leaves but also in other closures, especially in closures use without further integrity guarantee elements. It is Therefore, another object of the invention is a container closure system to provide, which has a cost-manufacturable indication of integrity.

These Task solves a container closure system with the features of claim 12.

This inventive container closure system has a container and a associated closure, wherein the closure has at least one tamper evident indicator, which is irreversibly destroyed in the Erstaufgelegt state on the container during a rotational movement of the closure relative to the container. The tamper-evident indicator is a jacket part of the closure, wherein this jacket part is strip-shaped and is connected at one end of the band via a hinge with the remaining sealing jacket. At the opposite end of the shell part it is connected via predetermined breaking points with the remaining sealing jacket. The tamper indicating device has an inwardly projecting nose which abuts against a wing of the container neck in the first applied condition.

Advantageous The indicator on this indicator is that after opening the bottle it is not considered to be loose part or lying down on the clasp, but after as before is arranged on the jacket and only protrudes. This looks on the one hand better. On the other hand, there is no loose part, which could be swallowed by a toddler.

Advantageous It is further that he is easy on the bottle can be applied without that special editing steps to close the scoreboard necessary. Furthermore impaired the scoreboard barely adapts to the design of the shutter adapt to different shapes of the closure.

The invention Safety guarantee element leaves but also in other closures, especially in Closures without use further health indicators. It is another task of the invention, a closure with an integrity guarantee element to create, which is easy to open is.

These Task solves a closure with the features of claim 13.

This invention container closure has a lower part, an over a hinge axis with this connected upper part and at least an integrity guarantee element, which in the first-closed Condition of the closure during a pivoting movement of the upper part is destroyed irreversibly relative to the lower part about the hinge axis. The integrity guarantee element has target bridge bridges, which are connected to the upper part. At the integrity guarantee element is a retaining band arranged, which at least one male element with at least a barb, which is in a recess of the lower part is pluggable.

The Warranty element leaves to solve themselves in different ways or remove. It can be completely or partially torn away or it can simply be pushed in become. Thus, the closure of anyone, including from handicapped or older Open people in a simple way become.

Further advantageous embodiments go out of the dependent claims out.

Ways to execute the invention

1 shows a closure according to the invention. It is designed as a snap hinge closure and manufactured in one piece from plastic by injection molding. He has a lower part 1 and a top 2 on which a movie hinge 3 known type are pivotally connected to each other about a hinge axis. Instead of the movie hinge 3 You can also use other known hinge types.

The lower part 1 serves the attachment to a container neck, in particular a bottleneck. The top 2 forms the lid of the lock ses and is in the open state, a spout opening free.

The closure has an integrity guarantee element in the form of a tamper-evident band 4 on. This tamper-proof band 4 connects in the first state the upper part 2 with the lower part 1 , being a pusher 20 covered like this in 2 is recognizable. This pusher 20 serves when opening the upper part 2 as a pressure surface for a finger, especially the thumb. The guarantee band 4 is above upper breakaway bridges 40 with the shell 2 connected, ie sprayed on this.

The guarantee band 4 can over lower break bridges 41 with the lower part 1 be connected. In the example shown here, however, is the guarantee band 4 a restraining bridge or a restraining band 5 molded. This restraint band 5 has two cuboid male members and a band connecting these elements band. There are barbs on the male elements.

The lower part 1 has two mutually spaced recesses 13 . 14 in which the two male members of the retaining band 5 are pluggable. The closure is injected in the open state and then closed. The male elements are in the recesses 13 . 14 stuck and thanks to their barbs can not be removed without destroying it. For the initial opening of the closure, the user now has various options: he can the guarantee strip 4 tear it away, taking it completely or only partially from the restraining band 5 can be removed. He can also use the guarantee band 4 in the area of the pusher 20 push in and the shell 2 open, whereby here again the break bridges 40 to the top 2 break. Preferably, the upper part 2 in this area of the guarantee band 4 a recess on to facilitate the impressions.

With both opening options, the restraint band lowers 5 down and gives the pusher 20 better free. This facilitates subsequent repeated opening of the closure and the retention band 5 is also optically nicely placed.

So that the guarantee band 4 can be completely removed when first opening in a simple manner or can be easily torn away, it has at one end a protruding handle 42 on how this particular in 3 is recognizable.

Completely from this guarantee band 4 separated and also spatially spaced is at least one tamper evident indicator 6 available. Like the guarantee band 4 indicates if the lid 2 already once from the lower part 1 has been raised, then the tamper evident indicator is used 6 as an indicator of whether the entire closure has already been removed from the container after it has been applied to the container. In contrast to the guarantee band 4 becomes the indicator 6 but not completely removed, but remains on the closure.

As in 1 recognizable forms the indicator 6 an integral part of the shell of the base 1 , It is band-shaped and runs at the bottom of the lower part 1 , At one end of the band he is over a joint 62 is connected to the rest of the closure shell and at an opposite end of the shell part he is on predetermined breaking points, here in the form of three predetermined breaking webs 60 , is connected to the remaining sealing sheath. The band-shaped indicator 6 has between its two ends a longitudinal extent, which is parallel to the circumference of the shell of the lower part 1 extends. In the first-closed condition of the closure on the container, the indicator follows the shape of the remainder of the jacket.

4 shows a longitudinal section through the inventive closure. Here it becomes clear that the closure is an internal thread 12 so that it can be screwed onto a corresponding external thread of a container neck in order to produce the first-closed or the first-applied state. However, the invention is not limited to closures with screw threads. It can also be realized in bottle necks with a bead or other connection options.

Furthermore, in 4 the spout opening 11 recognizable, which from the lower part 1 the lock is formed. This spout opening 11 is from a collar 21 of the top 2 surrounded so that a tight seal is created. Again, this is just one of many training opportunities. Preferably, the lower part also has 1 a down collar 10 to form a tight seal with the container neck, not shown in this figure.

In 5 is best seen that the closure, especially the lower part 1 , does not necessarily have to have a round cross-section. The closure shown here has a hexagonal shape, wherein the hexagon is designed uniformly. It is further evident that not only an indicator 6 but exactly two diagonally opposite indicators 6 available. These two scoreboards 6 are formed identically, wherein they have the same direction of rotation, ie the target break webs 60 point in the same direction. The scoreboard 6 each extend over a corner of the shell and thus have an angle. The indicator has it 6 in the area of this corner over a nose 61 which protrudes inwardly and which their step or edge to the predetermined breaking webs 60 has directed.

In 7 it is now apparent how the associated bottle must be formed. It must in the area of the inclusion of the closure, which is preferably formed by a neck, two radially outwardly projecting wings 71 or have noses. These wings 71 are arranged diagonally opposite each other and they have the same direction of rotation. One side of the wing 71 is slightly rounded, the other side forms a sharp edge. The edge is in each case to the edge of the nose 61 of the scoreboard 6 directed towards. In the first-concluded or Erstaufgebrachten state is the nose 61 the indicator on the wing 71 of the container 7 at.

The shutter can be removed without destroying the indicator 6 apply to the container neck. This is thanks to the joints 62 possible, which are preferably formed as thin bands. In 7 is the material rejuvenation in the area of the joints 62 good to see. These joints 62 give the scoreboard 6 some flexibility, so that the noses 61 with the wings 71 can be brought into engagement. This situation is magnified in 8th shown.

When twisting the shutter over the wings 71 away, however, break the predetermined breaking webs 60 , The joints 62 lead to the fact that the indicators protrude in approximately tangential direction of the closure shell and thus clearly indicate that the integrity is no longer guaranteed. This is in the 9 and 6 shown. Instead of these forces acting in the radial direction when first turning the shutter and axial forces may be present, which lead to breakage of the indicator. This is the case, for example, in the case of a bottleneck with a bead.

Of the invention Container closure thus allows a separate review of the first opening and the initial removal of the closure, wherein the integrity indicator a cost-effective and adaptable Element of the closure is.
