Definitions

  • the invention relates to a container closure according to the preamble of claim 1, a pouring element according to the preamble of claim 19 and a closure cap according to the preamble of claim 22.
  • closure caps With a tamper-evident band, closure caps are known which are held captive on the container and close its pouring opening.
  • the holding function is also important because legal provisions are being drawn up which will oblige the closures of beverage bottles to be permanently connected to the beverage bottle, even when open.
  • Another object is to show a captive closure cap, which does not prevent any use of the container to be closed.
  • the invention is characterized in that the guarantee strip has a first and a second end, the first end being firmly connected to the open edge of the threaded part and the second end being connectable to the pouring element.
  • the closure cap is therefore held captive on the pouring element after it has been unscrewed from the pouring element.
  • This solution makes it possible for the tamper-evident band to have a small height and accordingly little plastic material is required to produce the tamper-evident band or the closure cap.
  • a retaining band is necessary, which is detached from the tamper-evident band.
  • the height of the guarantee band must therefore be increased in comparison to other guarantee bands without the locking cap holding function. This leads to an increased amount of material used, which can be twice as high as with conventional guarantee tapes.
  • the second end of the guarantee strip can be connected to the pouring element by a form fit.
  • the connection can be established automatically by twisting the cap and, once the connection has been established, can only be released again if it is destroyed. Therefore, the closure cap is reliably held on the pouring element after opening.
  • a first hook is formed on the second end of the guarantee tape, which hook can be latched in at least one first recess which is provided on the pouring element and faces the first hook.
  • the design of the second end as a hook enables the connection between the tamper-evident band and pouring element to be made automatically by rotating the closure cap in the opening direction, without a further manual step being necessary to establish the connection. Through the connection, a thrust force can be applied to the tamper-evident band during the twisting of the closure cap, which leads to breakage of the predetermined breaking webs. After opening the closure cap, the closure cap hangs on the pouring element via the tamper-evident band.
  • the pouring element expediently has a neck and a collar that closes on the neck. This shape is common for pouring elements and has the additional advantage that the first recess can be formed on the neck or the collar.
  • the at least one first recess is formed on the neck in such a way that the first recess lies in a plane oriented orthogonally to the collar and to the neck.
  • the first recess is oriented in such a way that the first hook is inevitably rotated into the first recess when the closure cap is rotated.
  • the at least one first recess is formed on the collar in such a way that the first recess lies in a plane oriented orthogonally to the collar and to the neck.
  • the first hook is inevitably rotated into the first recess.
  • the first recess is formed on the collar, the neck or at the transition between the neck and the collar depends on the design of the first hook. It is essential that the hook is automatically rotated into the first recess and that it is not missed or that it is rotated past the water outside the first recess.
  • a recess is designed such that the first hook can be rotated into the at least one first recess when the threaded part is rotated in the opening direction.
  • the first hook can be made in any shape.
  • the cutout separates the first end from the second end of the guarantee band.
  • At least one guide element is formed on the neck, which leads the first hook into the at least one first recess when the threaded part is rotated in the opening direction.
  • the hook is positively guided when the closure cap is rotated and is reliably pressed into the first recess by the guide element.
  • the guide element is a ramp-shaped elevation on which the first hook can be guided by rotating the threaded part in the opening direction downwards in the direction of the at least one first recess. The ramp shape can be easily removed from the mold during manufacture and ensures precise, positive guidance of the first hook.
  • the at least one first recess on the collar is formed such that the first recess lies in the plane of the collar.
  • a counter-hook is formed within the at least one first recess, which can be detachably hooked to the first hook.
  • the barbed hook ensures that the tamper-evident band is held firmly on the pouring element and can no longer come loose.
  • the closure cap is held captive on the pouring element. It goes without saying that the connection between the first hook and the first recess can be loosened under increased application of force, which leads to the destruction of the first hook. In principle, however, provision is made for the container to be disposed of together with the closure cap after use.
  • the invention is also preferably characterized in that the first end and the second end of the guarantee strip are connected to a guarantee web, which guarantee web breaks when the threaded part is rotated in the opening direction.
  • the guarantee teg reliably shows whether the container closure is originally closed or not. It is conceivable that the breaking of the predetermined breaking webs when opening the closure cap can be avoided by manipulation. Therefore, the guarantee bar provides a further quality assurance for the container closure.
  • the guarantee bar is preferably arranged at the lower edge of the guarantee band.
  • the guarantee bar can, however, also connect the first and second ends of the guarantee band at another point, for example at the upper edge of the guarantee band. It is essential that the guarantee bar breaks when the closure cap is twisted or the guarantee band is manipulated.
  • a second recess is provided at the second end of the guarantee tape, which with at least one on the The pouring element, the second hook facing the second recess can be latched.
  • This embodiment represents a further possibility to fasten the guarantee tape to the pouring element while the closure cap is being screwed on. In principle, this embodiment is based on the same functional principle as the embodiments described above.
  • the second recess can be hooked onto the at least one second hook when the threaded part is rotated in the opening direction.
  • the at least one second hook is expediently formed on the neck. In this position, the second hook is oriented such that the second opening is reliably hooked onto the second hook by turning the closure cap.
  • the neck is free of a retaining ring for retaining the guarantee strip on the pouring element.
  • the pouring element is intended to be attached to a beverage carton or a container made from a composite material or is intended to be an integral part of a plastic container.
  • the container closure can be used on almost all known beverage containers.
  • the device features described above can be implemented using customary manufacturing processes.
  • the first hook and the first recess, which interacts with it, can be implemented without great effort during the manufacture of the closure cap and the pouring element.
  • Another aspect of the invention relates to a pouring element which has one or more of the features described above.
  • the pouring element interacts with a separately produced closure cap which is attached to the pouring element is adapted so that the closure cap is held with the tamper-evident band on the pouring element.
  • closure cap which has one or more of the features described above.
  • the closure cap interacts with a separately produced pouring element which is adapted to the closure cap so that the closure cap is held on the pouring element with the guarantee band.

  • the closure cap is made of a plastic material, preferably PP or HDPE.
  • a guarantee strip 31 is arranged on the open edge 29, which serves the purpose of indicating whether the container closure 11 is originally closed or not.

  • the predetermined breaking webs 33 break.
  • the broken or torn predetermined breaking webs 33 when the container closure 11 is closed, indicate that the container closure 11 has already been opened.
  • the aim of the invention is to ensure that the closure cap 15 is held captive on the pouring element 13 even after it has been unscrewed from the pouring element 13 and that as little material as possible is required for the proposed solution.
