  • the guarantee ring also represents a clearly visible guarantee security that is well known to consumers.
  • tearable webs are always arranged both between the anchor ring and the guarantee ring and between the closure cap and the anchor ring. While the bars between anchor ring and guarantee ring can be broken with a simple turning movement, the consumer has to use force to break the bars between anchor ring and cap. The tearing force is often too high for comfortable and easy opening.

  • the closure base can be a container neck formed in one piece with the container.
  • the closure base can also be a base element which is a further component of the closure device and is brought into connection with the container in order to provide a pouring spout for the container.
  • the closure device comprises a base element designed as a closure base, the base element comprising the guide means corresponding to the guide means of the closure flap.
  • a semi-finished product for a closure device comprising a closure cap with a cap cover extending radially to a closure axis and a cap jacket adjoining the cap cover on the circumferential side and extending axially, an anchor ring, a guarantee ring and a connecting element, wherein the Connecting element connects the closure cap to the anchor ring, the closure cap being connected to the anchor ring via at least one non-tearable web in addition to the connecting element, the connection element and the non-tearable web being designed and arranged in such a way that the closure cap relative to the anchor ring in is fixed in an essentially unchangeable position, the connecting element being designed in such a way that when a user uses the closure device resulting from cutting or punching the non-tearable web in connection with a closure base, the closure cap can also be pulled over the connecting element after an opening movement of the closure cap remains connected to the anchor ring, with a guide means being provided on the cap jacket of the closure
  • a semi-finished product is to be understood as an intermediate product in the production of a closure device, the intermediate product not being identical to the finished end product.
  • the semi-finished product can differ from the finished closure device in that at least one further process step of the manufacturing process must be carried out, e.g. cutting or punching, in order to arrive at a finished closure device.
  • a non-tearable web is understood to mean a web which cannot be torn with the ordinary physical force applied in everyday life by a consumer (user) of containers with closure devices.
  • a non-tearable web in the sense of the present invention is to be understood as a web that can only be torn or destroyed by applying an extraordinary amount of force--relative to the opening of container closures--or with the aid of tools.
  • the anchor ring and the at least one non-tearable bar are designed in such a way that the at least one non-tearable bar cannot be torn when the closure cap is opened for the first time, so that the guarantee ring cannot be detached from the anchor ring in this way.

  • the anchor ring has a projection protruding in the axial direction, which is arranged in a corresponding recess of the cap jacket when the closure cap is closed.
  • This combination of projection and recess serves to transmit a torque applied to the closure cap or the anchor ring, such as this acts when a consumer rotates the opening to open it, to the other element (anchor ring or closure cap). It is not absolutely necessary that the projection and the edge of the recess do not touch when there is no torque. Torque acting unilaterally on one of the anchor ring or cap elements (which occurs when the consumer grasps only one of the two elements during the opening rotary movement) causes a slight but sufficient relative displacement of the anchor ring and cap so that the protrusion and the edge of the corresponding recess engage so that the torque can be transmitted from the cap to the anchor ring or from the anchor ring to the cap.

  • the closure device is designed such that when the closure cap is opened for the first time, the tearable webs tear first and then the cutting element moves at least in sections through the inlet opening.
