- This combination according to the invention advantageously guarantees that the tamper-evident device can be used to see or feel whether or not the cardboard packaging has already been punctured or cut through.
- the closing device can manage with a minimal angle of rotation in order to move the cutting element into the maximum extendable position and thus open the cardboard packaging.
- the closure device is designed according to one of the closure devices according to the invention described above.
- the closure device and the cardboard packaging are designed in such a way that when the closure cap is rotated for the first time in the opening direction of rotation, the cutting element has engaged the cardboard packaging at a rotation angle D4 in such a way that the wall section of the cardboard packaging has an opening or a hairline crack , through which a liquid in the cardboard packaging can escape or through which germs located outside the cardboard packaging can get into the cardboard packaging, with the angle of rotation D4 being greater than the angle of rotation D1, with the angle of rotation D4 also starting from the angle of rotation zero point DO is measured.
- the angle of rotation D4 is generally smaller than the angle of rotation D3, but is at least as large as the angle of rotation D3 at most.
- This embodiment guarantees in an advantageous manner that the tamper-evident device can be seen or touched as to whether the cardboard packaging already has an opening through which a liquid in the cardboard packaging can escape or through which germs located outside of the cardboard packaging can get into the cardboard packaging could.
- the closing device can manage with a minimal angle of rotation in order to move the cutting element into the maximum extendable position and thus open the cardboard packaging.
- the wall section of the cardboard packaging can in particular have a sealing membrane, e.g. in the form of an aluminum layer, or a pre-embossing.

- the wall section of the cardboard packaging has a wall thickness to be measured in the direction of the closure axis, with the cutting element penetrating the cardboard packaging to a maximum depth of half the wall thickness if, when the closure cap was first turned in the opening direction of rotation, the angle of rotation D1 is reached. In this way, it can be ensured with a very high probability that the liquid-tightness of the cardboard packaging will only be weakened after or when the tamper-evident device has changed from the first state to the second state.
- the wall section of the cardboard packaging has a wall thickness to be measured in the direction of the closure axis, with the cutting element penetrating the cardboard packaging to a maximum depth of one quarter of the wall thickness if the first time the closure cap was turned in the opening direction of rotation, the angle of rotation D1 is reached.

- Figure 7c is a cross-sectional view of the closure cap of Figure 7b along line C-C.
- the closure device 1 has a base element 2 , a closure cap 3 , a cutting device in the form of a cutting ring 18 , an anchor ring 4 and a connection element designed as a connection band 5 .
- the connecting element can also be designed as a hinge in both embodiments.
- the closure devices 1 are intended to be connected to a container in the form of a cardboard package.
- the base element 2 has an annular flange 6 which is connected to the outer surface of the cardboard packaging.
- a hollow-cylindrical section 7 of the base element 2 extends from this flange 6 essentially perpendicularly thereto.
- This hollow-cylindrical section 7 is used for pouring liquid out of the cardboard packaging (not shown in the figures).
- the hollow cylinder 7 defines a channel 9 extending along the closure axis 8. This channel 9 comprises an inlet opening 10 on its lower side facing the cardboard packaging and a pouring opening 11 on its side facing away from the cardboard packaging.
- the position of the inlet opening 10 is axially where the flange ring 6 of the base element 2 extends.
- the wall section of the cardboard packaging covers the entrance opening before the closure device is opened for the first time and the cardboard packaging is thus opened.
- the hollow-cylindrical section 7 has an external thread 12 .
- This external thread 12 interacts with an internal thread 13 of the closure cap 3 .
- the closure cap 3 can therefore be screwed off and back onto the hollow-cylindrical section 7 of the base element 2 . In this way, the user can switch between the open state and a closed state of the closure device 1 .
- the embodiments shown can have a bayonet element arranged on the base element, e.g. B. in the form of a guide channel, and a hereby engageable, arranged on the closure cap bayonet element. e.g. B in the form of a guide tooth. It is crucial for the following considerations that the closure cap 3 remains attached to the base element 2 by means of the connecting band 5 and the anchor ring 4 even after the closure device 1 has been opened, ie after the closure cap 3 has been disengaged from the base element 2 .
- tearable connecting webs 14 between the anchor ring 4 and the tether 5 but also between the tether 5 and the closure cap 3 serve as a tamper-proof device within the meaning of the present application.
- closure cap 3 When the closure cap 3 is opened for the first time, i.e. when the closure cap 3 is screwed on, these webs 14 tear and the broken or torn webs 14 are visible to an observer. It can be seen whether the protective device 1 has already been opened for the first time.
- the anchor ring 4 In addition to the task of connecting the closure cap 2 to the base element 2 after it has been screwed on, the anchor ring 4 also has the task of providing the necessary counterforces when the closure cap 2 is unscrewed for the first time, so that the webs 14 tear or break.
- the anchor ring 4 is only fixed to the base element 2 in the axial direction, i.e. parallel to the closure axis 8.
- the anchor ring 4 together with the closure cap 3 can be freely rotated relative to the base element 2 .
- the anchor ring 4 can be rotated over a full 360 degrees and possibly a multiple thereof.
- the base element 2 has on its outer wall a projection 16 extending in the form of a circular ring on the outer wall. Snapping lugs 17 extending radially inward on the anchor ring 4 engage under this projection 16. These snapping lugs 17 snap in place axially under the projection 16 of the base element 2 when the closure cap 3 is fitted with the anchor ring 4 for the first time on the base element 2.
- the anchor ring 4 is thus axial direction parallel to the closure axis held by the projection 16.
- the cardboard packaging is completely closed, ie the wall section of the cardboard packaging extends over the entry opening 10 of the channel 9 of the base element 2 .
- the closure device 1 has the cutting ring 18 for this purpose.
- This cutting ring 18 extends in the channel 9 of the base element 2 and has an essentially hollow-cylindrical structure. In the embodiment shown here, the cutting ring 18 has four cutting elements in the form of pointed cutting teeth 15 .
- the cutting ring 18 is designed in such a way that it interacts with a grooved guide 20 provided in the inner wall surface 19 of the base element 2 .
- the cutting ring 18 is guided on the inner wall surface 19 in such a way that it moves axially in the direction of the wall section of the cardboard packaging when the closure cap is rotated for the first time relative to the base element in the direction of opening rotation.
- the cutting teeth 15 of the cutting ring 18 pass through the inlet opening 10 of the channel 9 at a time determined by the design.
- the cutting teeth 15 cut through the cardboard packaging in the area of the inlet opening 10 of the channel 9 and open the packaging so that liquid can escape from the cardboard packaging through the inlet opening 10 Channel 9 can flow in.
- the cutting of the cutting teeth 15 into the cardboard packaging can additionally be preceded by a deformation of the wall section of the cardboard packaging.
- the wall section can then be correspondingly deformed and the cutting teeth 15 are correspondingly blunt.
- the closure cap 3 In order to actuate the cutting ring 18, i.e. to unscrew it in the direction of and through the inlet opening 10 of the channel 9, the closure cap 3 has a driver device in the form of two driver elements 21. Starting from the top plate 23 of the closure cap 3 , these driver elements 21 extend in the axial direction into the channel 9 . When the closure cap 3 is rotated in the opening direction of rotation for the first time, the driver elements 21 come into engagement with complementary stop surfaces 22 of the cutting ring 18 . A rotational movement of the closure cap 3 when it is opened for the first time is thus transferred to a rotational movement of the cutting ring 18. The closing cap 3 and the cutting ring 18 move in opposite directions in the axial direction. The driver elements 21 and the stop surface 22 are in engagement with one another until the cutting ring 18 has reached a specific position in which the cutting teeth 20 extend as far as possible out of the entry opening into the cardboard packaging.
- the webs 14 must break at a rotation angle D1 and the cutting teeth 20 must pass through the inlet opening 10 at a rotation angle D2, with the rotation angle D2 being smaller than the rotation angle D1.
- the first complete penetration of the cardboard packaging must take place at a rotation angle D3, with the rotation angle D1 being smaller than the rotation angle D3.
- a delay in the passage of the cutting teeth 15 through the inlet opening 10 is not mandatory for the implementation of the present invention, but only advantageous.
- Embodiments of the invention are also conceivable which have an additional anti-tamper ring on the side of the anchor ring 4 facing away from the closure cap 3, the anti-tamper ring being connected to the anchor ring 4 via at least one tearable web, with this tearing at least one web when the rotation angle D1 is reached .
- the figures numbered “a” each show isometric views of the closure device 1 .
- the drawings numbered “b” show the closure device 1 viewed from below, ie from the cardboard packaging.
- the figures numbered “c” are each cross-sectional views taken along the lines indicated by the letters in the figures numbered "b".
- Figures 1a to 1c show the first embodiment of the closure device 1 in its original position, as it is applied to the cardboard packaging, i.e. before the closure cap 3 is screwed on for the first time.
- Figures 2a to 2b show the closure device 1, wherein the closure cap 3 was rotated starting from the rotation angle zero point DO up to a rotation angle D1.
- FIGS. 3a to 3c show a position of the closure device 1 in which the cutting teeth 15 of the cutting ring 18 look out of the inlet opening 10 at most.
- the cutting ring projects out of the inlet opening by more than 3 mm in this position.
- the wall section (not shown) of the cardboard packaging has now been completely penetrated by the cutting ring.
- the penetration of the cutting teeth 15 through the input opening 10 is delayed by an increased axial spacing of the cutting teeth 15 from the input opening 10. Since in this embodiment the delay until the start of the Cutting process, ie the engagement between the cutting teeth 15 and the cardboard packaging is caused by the increased stroke, the engagement between the stop surface 22 of the cutting ring 18 and the driver element 21 can already begin at a very small angle of rotation. It is even possible that this intervention takes place at an angle of rotation equal to zero, ie at the zero point DO of the angle of rotation, or shortly thereafter.
- the stroke can be reduced to a minimum by the present invention, since the leeway for changing the tamper-proof device from the first state to the second state is optimally utilized, namely only after or when the cutting teeth pass through the input opening and in any case before completely severing the wall section of the cardboard packaging initially covering the entry opening.
- Figures 5a to 5c show the second embodiment of the closure device 1 in its original position, as it is applied to the cardboard packaging, i.e. before the closure cap 3 is screwed on for the first time.
- FIGS. 6a and 6b show the closure device 1 when this rotation angle D1 is reached starting from the rotation angle zero position D0.
- FIGS. 7a to 7c show a position of the closure device 1 in which the cutting teeth 15 of the cutting ring 18 look out of the entry opening 10 at most. In this position, the driver elements 21 can again be disengaged from the stop faces 22 of the cutting ring 18 .
- the open closure according to the second embodiment then does not differ from the illustration in FIG.
- FIGS. 5a to 7c the webs 14 are torn off or broken at the same time as the cutting teeth pass through the inlet opening for the first time, so that the angle of rotation D1 is equal to the angle of rotation D2.
- FIGS. 1a to 4 on the one hand and FIGS. 5a to 7c on the other hand show two different implementations of the delay, mixed forms are also conceivable in which the engagement of driver element and stop surface is delayed and at the same time the stroke of the cutting teeth is also increased.
