  • top etc. is always to be understood as an indication of position or direction, which refers to the axial direction pointing in the direction of the lid section (for the closure cap) or in the direction of the pouring opening (for the container).
  • Down etc. is to be understood as meaning a position or direction that points in the exact opposite axial direction (rotated by 180 degrees).

  • inside etc. always means a position or direction that points radially in the direction of the closure axis or container neck axis

  • the affected containers with closure caps are in the form of bottles or canisters for liquids, typically in the agricultural sector or in the chemical industry, for example for fertilizers, cleaning liquids, etc., widespread.
  • Such containers are generally made of plastic and, in combination with appropriate closures, they have means which visually indicate to a consumer that the closure has been opened for the first time.
  • the closure cap is in the form of a screw cap having a head plate and a cylindrical internally threaded cap skirt which mates with the external threads of the container finish.
  • guarantee strips also known as TE strips - which are attached to the closure cap, more precisely to the lower edge of the jacket of the Cap, are connected that they tear in the event of a manipulation attempt or opening of the cap.
  • TE stands for the English term "Tamper Evidence”.
  • connection between a tamper-proof band and the remaining components of the closure cap must break or tear with sufficient ease in the event of manipulation attempts, but also during regular opening, among other things so that opening by hand is not unnecessarily difficult.
  • the anti-tamper strip must also be sufficiently firmly connected to the remaining components of the closure cap so that the connection is not damaged or completely or partially torn off when the closure cap is attached to the container neck.
  • the anti-tamper strip is connected to the cap jacket of the closure cap, for example via a weakened, thin-walled wall section or via a number of easily torn bridges.
  • the guarantee strip has latching elements on its inside, e.g. latching teeth, which are designed in such a way that during and after a container is closed they engage with correspondingly designed latching elements on the container neck, e.g. the teeth of one on the container neck arranged toothed ring, engage and prevent rotation of the anti-tamper strip in the opening direction.
  • the latching elements of the closure cap often also form a toothed ring together, so that two toothed rings face each other when the closure cap is connected to the container neck.
  • the teeth of the toothed ring of the container neck are usually also designed in such a way that the latching teeth of the guarantee strip can slide over the tips of the teeth of the toothed ring in the closing direction when the container is closed for the first time without the guarantee strip tearing off the closure cap completely or partially. Only when the closure cap is turned in the opening direction do the teeth of the toothed ring of the container neck engage with the latching teeth of the guarantee strip in such a way that they prevent the guarantee strip from rotating with the remaining components of the closure cap. As a result of the opening process, the anti-tamper strip then completely tears off the closure cap jacket.
  • the tips of the teeth of the toothed ring define a maximum radius of the toothed ring, which is also referred to here as the “first radius”.
  • These teeth are preferably arranged in such a way that they are all or at least predominantly arranged on the same radius with respect to the central axis of the external thread.
  • the minimum radius of the toothed ring is generally at least as large as the nominal radius of the external threads on the container finish in order to avoid interference between the ratchet teeth of the tamper-proof band and the threads on the container finish when the closure is applied to a container finish.
  • the tips of the teeth could also be arranged on partially different radii with respect to the central axis. Similarly, not every tooth base between adjacent teeth has to have the minimum radius.
  • the guarantee bands with ratchet teeth have no positive or frictional connection with the container neck that is effective in the axial direction, since the ratchet teeth engage loosely in the tooth gaps and are only secured against rotation in the opening direction.
  • Any axial retaining rings, such as are customary and necessary on the container neck for other tamper-proof strips, such as flex strips, are generally not present in tamper-proof strips with locking teeth, since these would prevent a closure cap with the tamper-proof strip from being screwed onto the container neck.
  • guarantee bands with locking teeth offer a high level of security against tampering, especially with closures with large diameters of between 50 and 80 mm, for example, so that they are often used for large containers such as canisters.
  • the guarantee band loosely surrounding the toothed ring can be removed from the container neck or fall off when the container is tilted to pour out the contents (eg a liquid) contained therein.
  • the tamperproof strip can slip off the neck of the container and fall into another container into which the filling material contained in the container is to be poured.
  • a liquid that is in the container are filled into a mixer or a portioning system, with a Guarantee tape accidentally falling into such a container or mixer can lead to significant operational disruptions.
  • This fall off of the tamper evident band due to gravity is particularly troublesome when the ring falls into a fluid tank connected to a machine such as a large crop protection sprayer or a hydraulic tank on a hydraulically operated machine.
  • the present invention is therefore based on the object of creating a closure cap and a container with a container neck which largely prevent unintentional detachment from a container neck of a guarantee strip which has already been separated from the remaining components of the closure cap.

  • At least one blocking element is arranged on the guarantee band of the closure cap, the blocking element having a second stop surface with a surface normal pointing at least partially in the axial direction so that the second abutment surface can be brought into engagement with a second abutment surface of the container neck when the closure cap is in the assembled state with the container, with the engagement of the two second abutment surfaces exerting a holding force acting in the axial direction on the guarantee strip when the container is Pouring a filling is tilted.
  • the invention is based on the idea that the blocking element of the closure cap and its interaction with a container neck prevent the anti-tamper strip from detaching from the container when the container is tilted. For example, this prevents the tamper evident band from falling off when a canister fitted with the tamper evident band and having a standard top opening is tilted more than 90 degrees from its standing position.
  • the latching elements alone block only a rotary movement of the anti-tamper strip in the opening direction of the closure cap, which corresponds either to the circumferential direction in a clockwise direction, but in most cases to the circumferential direction counterclockwise.

  • the blocking element is a radially inwardly protruding projection starting from the anti-tamper strip, the projection preferably being formed in one piece with the anti-tamper strip, or a radially outward-protruding depression in the anti-tamper strip.
  • the blocking element is a radially inwardly protruding projection starting from the anti-tamper strip.
  • a projection can be easily and simply produced in the injection molding process and represents a good compromise between the desire for minimal use of material on the one hand and the desire for reliable securing of the anti-tamper strip in the axial direction before detachment.
