  12. 12. Container closure (10) according to one of the preceding claims, characterized in that the mouthpiece cover (20) is connected to the cap (12), in particular to the central region (19) of the cap (12), via at least one latching connection that can be released by an external force.

Description

DESCRIPTION CONTAINER CLOSURE The invention relates to a container closure according to the features of the respective preamble of the two independent patent claims. From DE 10 2014 207 652 A1 a container closure (1) is known, comprising a closure bottom part (5) and a cap (2) as well as a mouthpiece (3) and means for piercing a closure film, wherein a guarantee band (6) is provided which ensures that the closure film can only be pierced by the means when the guarantee band (6) has been removed, wherein the guarantee band (6) is arranged between the closure bottom part (5) and the cap (2). The reference numbers refer to the above-mentioned document. Furthermore, DE 10 2017 100 184 A1 discloses a container closure (1) having a closure bottom part (5) and a cap (2) as well as a mouthpiece (3) and means for piercing a closure film, wherein a guarantee band (6) is provided which ensures that the closure film can only be pierced by the means when the guarantee band (6) has been removed, wherein the guarantee band (6) is arranged between the closure bottom part (5) and the cap (2), wherein the guarantee band (6) is designed as a closed ring which is connected to a lower edge of the cap (2) via at least one separable web (8) and the cap (2) is mounted on the closure bottom part (5) in sections such that it can be rotated and pressed. The reference numbers refer to the document mentioned above. The invention is based on the object of improving a known container closure with a guarantee band (sealing ring) with regard to its handling and its environmental compatibility. This task is solved by the guarantee band having several predetermined breaking points aligned in the axial direction of the container closure and being activated by a spreading process. Before the predetermined breaking points are separated, it is easy to see and check that the guarantee band has not yet been activated, i.e. that the container closure is still intact. When activated, the predetermined breaking points, which are distributed around the circumference of the container closure, are separated by simply pressing, so that the container closure is easy to handle. After pressing, the guarantee band is press-fitted to the container closure and remains on it, so that all parts can be disposed of together, in particular recycled, without individual parts of the container closure being lost and polluting the environment. The spreading process can also be carried out in different ways. On the one hand, it is conceivable that the cap is unscrewed from its original state and the guarantee band is spread with the rotation. After this has taken place, it is possible for the cap to be pressed down in the direction of the container on which the container closure is attached, in particular screwed on, in order to actuate the means for piercing the sealing film. This makes it possible for an additive which is arranged in the lower part of the closure to be released and to move in the direction of the container. On the other hand, it is conceivable that the cap is first unscrewed from its original state without the guarantee band being spread. The guarantee band is only spread when the cap is pressed down in the direction of the container in this state. In a simpler version of the two variants mentioned above for operating the cap and the resulting spreading of the guarantee band, it is conceivable that the cover of the closure (more precisely the mouthpiece) can be operated, i.e. opened, independently of this. If the cap initially remains in its original state (delivery state), it can be considered that to open the mouthpiece cover without the cap being turned. This makes the means for piercing the sealing film accessible and can be pressed down towards the container to pierce the sealing film. Although this means that the additive in the lower part of the closure can get into the container, the area for actuating the means for piercing is relatively small, so that higher forces must be applied. To avoid these higher forces, in another and therefore improved variant, the guarantee band is activated when the mouthpiece cover is not actuated, i.e. by twisting or by a linear movement of the cap, it spreads and thus breaks open at least one predetermined breaking point. By breaking open the predetermined breaking point, the cap can be moved from its first position (delivery state) to a further position, which simultaneously means that the means for piercing the sealing film are also moved along with this movement. Since this movement involves pressing the cap down towards the container, the free surface of the mouthpiece cover means that a larger area is available for activating this movement, so that less force is required to activate the means for piercing the sealing film. After the means for piercing the sealing film have been activated, the additive in the lower part of the closure enters the container. At the same time, the means for piercing remain i
