Definitions

• the present invention relates to a container closure and a container according to the preamble of the independent claims.
• US 2010/0326948 A1 shows, for example, a container closure that has a guarantee seal. Guarantee seals or quality seals are elements that enable a buyer, for example, to visually or tactilely check the integrity of a container.
• the guarantee seal of the container closure of US 2010/0326948 A1 is also designed as a securing element which prevents the container closure from being completely removed from the bottle.
• the guarantee seal is rotatably mounted on the container. When the container closure is unscrewed, it is rotated with it until a sufficiently high level of tension is built up in the guarantee seal and it breaks. A sufficiently long thread must be provided in order to build up the required tension. This requires a considerable size. There is also the risk that the guarantee seal may become wedged or stuck on the container while the container closure is being opened and accordingly breaks too early. There is then the risk that the securing element will tear off if the container closure is opened further.
• the object of the invention is to remedy one or more disadvantages of the prior art.
• This object is achieved by the devices defined in the independent patent claims. Further embodiments emerge from the dependent claims.
• a container closure according to the invention comprises a closure cap with an internal thread for application to a pouring opening with an external thread.
• the container closure comprises a connecting element with a first end and a second end.
• the first end of the connecting element is connected to the closure cap.
• the connecting element runs at least partially along a circumference of the closure cap.
• the second end of the connecting element is fixed or fixable in a rotationally fixed manner with respect to the pouring opening and is arranged outside the closure cap.
• At least one tear-off bar is formed on the connecting element.
• a plurality of tear-off webs are preferably formed on the connecting element.
• the arrangement of the second end of the connecting element from within the closure cap makes it possible to manufacture the closure cap with a lower overall height.
• an internal thread, which is arranged or formed in the closure cap, can be brought into connection over its entire height with a corresponding external thread of a pouring opening.
• connection element enables the closure cap to be held after opening with the connection element on the container on which the pouring opening is arranged.
• the closure cap is permanently connected to the container.
• the rotationally fixed arrangement of the second end of the connecting element in relation to the pouring opening ensures that the second end of the connecting element assumes a defined position in relation to the pouring opening.
• This conditional, fixed position ensures that the first end of the connecting element, which is arranged on the closure cap, moves, in particular rotates, relative to the second end when the container closure is opened. In other words, the relative position of the first end to the second end of the connecting element is changed when the container closure is opened.
• Tear-off webs that are formed on the connecting element enable a quality seal to be provided. This allows the container to be checked; in particular, the quality seal enables a so-called tamper-evident guarantee. The buyer can thus determine whether the container closure has already been opened once or not.
• the tear-off webs are in particular designed in such a way that they are torn off or broken open, in other words, separated by the relative rotation of the first end of the connec tion element relative to the second end of the connection element.
• the pouring opening is preferably designed as a circular cylindrical hollow body which has a first opening into an interior of a container and a second opening for dispensing a medium, for example a beverage.
• the pouring opening thus has a wall on or on which the external thread can be formed.
• the second opening for dispensing the medium has a contact element with one or more contact surfaces.
• the contact element, in particular the contact surfaces, are designed with corresponding contact surfaces of the cap to come into operative connection and to seal the interior of a container from the environment.
• the connecting element can wrap around the cap over a looping angle of 30 °.
• the connecting element preferably wraps around the closure cap over a wrap angle of more than 45 °, preferably over more than 90 °, in particular over more than 180 °.
• the connecting element is preferably arranged completely outside the closure cap.
• the entire closure cap is available for forming an internal thread. That is to say, the closure cap can essentially be formed over its full height to interact with a corresponding external thread and can be used accordingly.
• both the closure cap and the pouring opening can be manufactured with a lower overall height. This saves material while maintaining the same strength or strength of the connection.
• the at least one tear-off web can be formed between a first partial section of the connecting element and a second Operaab section of the connecting element. Additionally or alternatively, the at least one tear-off bar or one or more further tear-off bars between the connecting element ment and the cap. It is conceivable that a plurality of tear-off bars are formed in each case.
• the connecting element is preferably arranged in a meandering manner.
• the connecting element can thus be arranged outside the closure cap in a space-saving manner.
• the meander-shaped arrangement enables a simple formation of the tear-off webs between a first section of the connec tion element and a second section of the connection element.
• the connecting element preferably runs from its first end in the direction of the direction of rotation when opening the closure cap along the circumference of the closure cap.
• the container closure may comprise a fitting for attachment to a container.
• the container is in particular a cardboard container.
• the pouring opening is etcbil det on the fitting.
• the second end of the connecting element is preferably arranged on the shaped piece.
• the arrangement of the second end of the connecting element on the shaped piece and the formation of the pouring opening on the shaped piece ensures that the second end of the connecting element is arranged in a rotationally fixed manner with respect to the pouring opening.
• the container closure can be provided as a complete unit with an intact quality seal.
• closure cap and the connecting element can be formed in one piece.
• the container closure can be made of a polyolefin, in particular polyethylene or polypropylene or one of their mixtures. Alternatively, it can be made from PET or from PET-G or from PCT-G or from a bioplastic or from a polystyrene blend.
• the material of the container closure can be selected according to the desired properties. In particular, when container closures for carbonated drinks are used, a certain strength of the material is desired.
• Another aspect of the invention relates to a container, in particular a beverage container, comprising a container closure as described herein.
• a container closure as described herein By providing a container with a container closure as described here, a complete package can be provided.
• the second end of the connecting element is connected to the container, that is to say is fixed directly to the container.
• the second end can be glued directly to the container, for example be fixed.
• a corresponding surface or a corresponding element is also formed on the container, to which, for example, the second end of the connecting element can be fixed.
• the second end of the connecting element is preferably fixed to the container by means of an ultrasonic welding.
• connection options described here are formed accordingly between the molded piece and the second end of the connecting element.
