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.
  • the guarantee closure has the disadvantage that the closure cap can perform dancing movements, so that the closure cap can bump against the face in an uncontrolled manner, which is very uncomfortable is felt.
  • the cited document discloses a container with a recess specially provided for holding the closure cap.
  • Such a configured container has the disadvantages that its manufacturing costs are relatively high that for such containers require special production, and that the extremely widespread standard beverage bottles, which have no recess for holding the cap, can no longer be used if one wants to prevent the cap from dangling and dancing.
  • the document WO2019/207153A2 discloses another captive tamper evident seal for opening and closing a container.
  • This guarantee closure is designed in such a way that the closure cap is guided in two places and can be turned or tilted to the side like a hinge, so that after the guarantee closure has been opened the closure cap is positioned on the side of the container neck at a point on the container neck determined by the guarantee closure.
  • 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.
  • the object of the invention is to create a more advantageous tamper evident closure that is more convenient to handle and which is particularly suitable for use with standard beverage bottles.
  • the dependent claims 2 to 12 relate to further advantageous configurations.
  • the object is further achieved with a method for opening a guarantee closure comprising the features of claim 13.
  • the dependent claims 14 to 15 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, comprising a securing ring, which is arranged following the closure cap and running concentrically to the closure cap axis in the direction of the closure cap axis, comprising a plurality of predetermined breaking webs, through which the closure cap is connected to the securing ring, the closure cap being broken by breaking the predetermined breaking webs from the Securing ring is separable, and comprising a single retaining strap, which is connected at its first end to the closure cap and at its second end to the retaining ring, 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 the second arm, the first arm and the second arm running in the circumferential direction with respect to the axis of the closure cap, the retaining strap having a length which permits the closure cap and
  • the object is also achieved in particular with a method for opening a guarantee closure which closes a pouring opening of a container, the guarantee closure having a closure cap with a closure cap axis, a securing ring connected to a container neck of the container, which in the direction of the closure cap axis following the closure cap and concentrically to the is arranged running along the closure cap axis, and comprises a single retaining strap, the retaining strap being U-shaped or V-shaped and running in the circumferential direction with respect to the closure cap axis, and the retaining strap being connected at its first end to the closure cap and at its second end to the retaining ring is connected by starting with a guarantee closure that has never been opened, the closure cap to be opened for the first time is raised from a starting position in the direction of the axis of the closure cap, by the closure cap being removed from the pouring opening and being positioned laterally on the outside of the container neck, and by the closure cap, due to the spring properties of the retaining strap, on the one hand automatically
  • the guarantee closure according to the invention must meet the condition that the closure cap remains connected to the container even after the pouring opening of a container, eg a beverage bottle, has been opened.
  • the guarantee closure according to the invention includes only a single retaining strap, so that the closure cap does not open as in the document WO2019/207153A2 disclosed hinge-like tilting movement, but can be moved in a plurality of directions.
  • the guarantee closure according to the invention therefore has the advantage that the closure cap can be arranged in different positions with respect to the container neck of the container after the guarantee closure has been opened, depending on other boundary conditions or preferences.
  • a left-handed person or a right-handed person can arrange the sealing cap of the guarantee seal in relation to the container neck in such a way that the liquid can be conveniently poured into a drinking cup, or it is possible to drink comfortably by mouth directly from the container.

  • the guarantee closure according to the invention is also designed in such a way that, after opening, the closure cap can be placed back onto the container neck and the latter can be closed.
  • the guarantee closure according to the invention can thus be used several times be opened and closed again, whereby the tamper evident seal essentially retains its mechanical properties, in contrast to the document WO2019/207153A2 disclosed embodiments, in which parts of the guarantee seal must be excessively stretched during the initial opening, so that the guarantee seal after the first opening, due to the overstretching of certain components of the guarantee seal, has a changed mechanical behavior, or that the closure cap due to the overstretching only with additional effort can be put back on the container neck.
  • the closure cap of the tamper-proof closure has a jacket surface running in the circumferential direction, with the retaining strap being designed in such a way that it does not protrude beyond the jacket surface in the radial direction.
  • a guarantee closure has the advantage that it essentially has the same external dimensions as a conventional guarantee closure without a permanently connected closure cap, so that the guarantee closure according to the invention can be used in automated bottling plants with little or no adjustment work.
  • the guarantee closure according to the invention has the further advantage that the part of the retaining strap forming the guarantee closure has no or only a negligibly small surface to attack from the outside, and the retaining strap is thus very well integrated in the guarantee closure, so that the guarantee closure according to the invention has an extremely low error rate during filling, and that the guarantee closure is extremely unlikely to be damaged during transport of the container.
  • the guarantee closure according to the invention is therefore ideally suited for existing, automated filling systems and for existing sales channels.
  • the tamper evident seal defines a tamper evident seal axis and the cap defines a seal cap axis.

  • the exemplary embodiment of a retaining strap 6 shown has particularly advantageous resilient properties, particularly in the direction of the closure cap axis AV, with the predetermined breaking webs 8, 9 and 14 being particularly advantageous when they are arranged at a relatively small distance from one another in the circumferential direction U.
  • Guarantee closures 1 shown are preferably opened in such a way that, in the case of a guarantee closure 1 that has never been opened, the closure cap 3 to be opened for the first time is raised from a starting position in the direction of the closure cap axis AV, as in FIGS Figures 4 and 5 shown by the closure cap 3 being removed from the pouring opening 33 is removed and positioned laterally on the outside of the container neck 31, such as in figure 6 shown, and in that the closure cap 3, due to the spring properties of the retaining strap 6, is pressed on the one hand automatically with a pretension to the outside of the container neck 31, and on the other hand in the direction of the closure cap axis AV , preferably automatically along the outside of the container neck 31 in the direction of the starting position is moved back, so that the closure cap 3, for example, in figure 6 , 7 or 8 position shown.
  • This stabilizing effect of the retaining strap 6 or the effect of aligning the closure cap 3 allows the closure cap 3 to be brought into contact with the outside of the container neck 31 in a particularly simple, pleasant and secure manner, as is shown in FIGS Figures 6 to 8 is shown.
  • the closure cap 3 after it has been positioned laterally on the outside of the container neck 31, can be rotated further by an angle of rotation ⁇ in the range between 80° and 190° about an axis of rotation A 1 running perpendicular to the guarantee closure axis AG , with the Closure cap 3, preferably due to the spring properties of the retaining strap 6, is then preferably automatically applied to a container neck ring 36 of the container neck 31, so that the closure cap 3 is held in a predetermined position with respect to the container neck 31.
