Definitions

  • the invention relates to a guarantee closure for closing a pouring opening of a container.
  • the invention also relates to a method for opening a guarantee closure.
  • a tamper-evident closure which is frequently used for beverage bottles, for example, comprises a screw cap and a securing ring, also referred to as a tamper-proof band, with the tamper-proof band being connected to the free edge of the screw cap via predetermined breaking points.
  • the screw cap comprises a cylindrical cap jacket with an internal thread, it being possible for the screw cap to be fastened to an external thread of the container via the internal thread.
  • the anti-tamper strip can preferably be latched, preferably on a neck of the container.
  • the guarantee closure has the disadvantage that the closure cap can make dancing movements, so that the closure cap can hit the face in different places in an uncontrolled manner, which is very is felt to be uncomfortable.
  • the document discloses a container with a specially designed for
  • Such a configured container has the disadvantages that whose production costs are relatively high, that a special design is required for such containers, and that the extremely widespread standard beverage bottles, which have no recess for holding the cap, can no longer be used if you want to prevent the cap from dangling and dancing.
  • the document WO2019/207153A2 discloses another captive guarantee closure for opening and closing a container.
  • This tamper evident closure is designed in such a way that the closure cap is guided in two places and is turned or folded to the side in the manner of a hinge. can be tilted so that after opening the guarantee seal the closure cap is positioned on the side of the container neck at a point on the container neck which is determined by the guarantee seal.
  • This guarantee closure has the disadvantage that the closure cap can be arranged in an unfavorable position and hinders pouring the liquid out of the bottle or drinking the liquid directly from the bottle by mouth.
  • Document JP2013230822A discloses a container closure comprising three parts, a cylindrical body with a closure plate, a closure cap and a circlip.
  • the cylindrical body can be connected to a threadless bottle neck of a container via a snap connection, the bottle neck having an outlet opening.
  • the separately manufactured closure cap and the separately manufactured securing ring each have an engagement part, via which these two separate parts can be connected.
  • the closure cap each comprises two separate connecting parts, which are connected to the engaging part.
  • This container closure has the disadvantage that it is not suitable as a guarantee closure, since the entire container The end can be removed from the bottle neck or from the outlet opening via the snap connection without having to break predetermined breaking points.
  • the predetermined breaking points therefore provide no indication as to whether the container closure was ever completely removed and reassembled, so that this container closure cannot guarantee that the container was never opened. If broken predetermined breaking points are found on this container closure, this is only an indication that the closure cap has been lifted in relation to the cylindrical body. With this container closure, it is also necessary to remove the closure plate in order to gain access to the container contents. Only a closure plate that is at least partially open gives an indication that access to the contents of the container has been gained via the container closure. In contrast to a guarantee closure, no indication can be derived from the condition of the predetermined breaking points of the container closure disclosed in the aforementioned document as to whether access to the container contents was gained via the container closure.
  • This container closure also has the further disadvantages that complex assembly of the closure cap and locking ring is required, that the two connecting parts are extremely vulnerable, that when the closure cap is rotated there is a risk of plastically deforming the two connecting parts or even tearing them off, and that the container closure not suitable for attachment to a container having a pouring spout with an external thread.
  • This container closure is also not able to guarantee that the closure cap remains captively connected to the container when the container closure is used once or several times. Presentation of the invention
  • the object of the invention is to create a more advantageous guarantee closure that is more comfortable and safer to use and is also particularly suitable for use with standard beverage bottles.
  • the dependent claims 2 to 15 relate to further advantageous configurations.
  • the object is further achieved with a method for opening a guarantee closure comprising the features of claim 16.
  • the dependent claims 17 to 18 relate to further advantageous method steps.
  • a guarantee closure for closing a pouring opening of a container comprising a closure cap with a closure cap axis and an internal thread, comprising a securing ring which is arranged following the closure cap in the direction of the closure cap axis and running concentrically to the closure cap axis, comprising a plurality of Predetermined breaking webs, through which the closure cap is connected to the safety ring, the closure cap being separable from the safety ring by breaking the predetermined breaking webs, and comprising a single retaining strap which is connected to the closure cap at its first end and to the safety ring at its second end, wherein the retaining strap is designed to run in a U-shape or V-shape and consists of a first arm, a second arm and a connecting section connecting the first and second arms, the first arm and the second arm extend in the circumferential direction with respect to the axis of the closure cap, with the retaining strap having a length which makes it possible to separate closing cap and locking
