DETAILED DESCRIPTION

[0075] The first embodiment of a closure device 1 according to the invention shown in FIG. 1 to FIG. 5 has a connecting device 13 with two holding bands, namely a first holding band 23 and a second holding band 24, and a fixing element 18. Before the closure device 1 is opened for the first time, the two holding bands 23, 24 are connected to the anchor ring 12 on the one hand and to the cap skirt 10 on the other hand via a total of two weakening lines 25, 26. When the closure device 1 is opened for the first time, these two weakening lines 25, 26 tear, so that the closure cap 8, as shown in FIGS. 3a, 3b, 5 and 5, remains attached to the basic member 2 via the two holding bands 23, 24namely via the anchor ring 12even when the closure cap 8 is lifted off in order to release the pouring opening 5.

[0076] For the purposes of the present application, a weakening line is a special formation of an easily tearable bridge and thus also provides a tamper-evident device.

[0077] In the embodiment shown in FIGS. 1 to 5, the two weakening lines 25 and 26 are configured such that, before the closure device 1 is opened for the first time, a first weakening line 25 connects the first holding band 23 to the cap skirt 10 and the second holding band 24 to the anchor ring 12, and that a second weakening line 26 connects the first holding band 23 to the anchor ring 12 and the second holding band 24 to the cap skirt 10. As can be seen in FIG. 1, the second weakening line 26 extends from a position on the second holding band 24 that is axially spaced from the first weakening line 25 in the direction of the pouring opening 5, sometimes also axially towards a position on the first holding band 23 that is axially spaced from the first weakening line 25 in the direction of the inlet opening 4.

[0078] The second weakening line 26 extends in a zig-zag manner, so that in the closed state of the closure device 1 a fixing element 18 is formed at a circumferential position between the two circumferential ends of the first weakening line 25, which is arranged on the cap skirt 10 as an axial extension of the cap skirt 10. The fixing element 18 and cap skirt 10 are configured in one piece. The cap skirt 10 and fixing element 18 are also essentially flush in the radial direction.

[0079] After the closure device 1 is opened for the first time, the closure cap 8 is pivoted out of the position shown in FIGS. 1 and 2 in order to bring it into the second, stabilised position of the closure cap 8 shown in FIGS. 3a, 3b, 4 and 5. The holding bands 23 and 24 are twisted by pivoting. The twisted holding bands cause a restoring torque which, without the presence of the support means 14 configured as a support ring, would cause the closure cap 8 to pivot at least partially back in the direction of the pouring opening 5. However, in the first embodiment of the closure device 1 shown here, the fixing element 18 initially comes into contact with the surface of the support means 14 aligned in the direction of the inlet opening 4 during pivoting. By applying a slightly increased torque, the person consuming the product then ensures that the fixing element 18 is lifted or pressed out of this position in the direction of the pouring opening 5 over the support ring, whereby a clearly audible clicking sound is emitted in the course of this. As a result, the fixing element 18 is in the position shown in FIG. 3a. In the embodiment shown here, this means that the fixing element abuts with its outer surface against the first edge 17 of the support ring. In this position, the support of the fixing element 18 on the first edge 17 of the support ring counteracts the restoring torque caused by the twisted holding bands, so that the closure cap 8 cannot be moved out of this position without the application of increased force by the person consuming it and is thus mounted in a stabilised manner.

[0080] Axially spaced from the support ring in the direction of the inlet opening 4, the basic member 2 has the fastening means 7 configured as a fastening ring, more precisely as a pilfer-proof ring. This fastening ring holds the anchor ring 12 and thus also the closure cap 8, which is connected to the anchor ring 12 via the connecting device 13, attached to the basic member 2. In the first embodiment shown in FIGS. 1 to 5, the anchor ring is configured as a flex band.

[0081] A flex band section of the anchor ring that is folded over in the direction of the closure axis 50 is in engagement with the fastening means 7.

[0082] The embodiment shown in FIGS. 1 to 5 also has an asymmetrical position of the two holding bands 23 and 24 in relation to each other when the closure cap 8 is in the second position. This can be seen in particular in FIG. 5.

[0083] For the purposes of the present application, an asymmetrical position of two holding bands is to be understood as an arrangement of two holding bands in which the connection point between the first of the two holding bands and the anchor ring is arranged closer (or further away, depending on the definition of the holding bands) to the closure cap than the connection point between the second of the two holding bands and the anchor ring.

[0084] The first guiding means 6 of the embodiment of the closure device 1 according to the invention shown in FIGS. 1 to 5 is configured as an external thread and the second guiding means 11 as a corresponding internal thread, whereby a rotation through a circumferential angle of approximately 180 degrees is necessary in order to disengage the external and internal threads from a fully closed position or to bring them fully into engagement with one another.

[0085] It can be seen from FIGS. 2 to 5 that the embodiment shown here also has a sealing membrane 19 initially closing the channel. A pull-off tab 20 is arranged on the sealing membrane 19. To release the channel 3, a person consuming the product only has to grasp the pull-off tab 20 with one finger and pull it upwards with the usual everyday force to separate the sealing membrane 19 from the inside of the channel.

[0086] It can be seen from FIGS. 1 and 2 that an annular inner seal 21 extends from the inside of the cap cover 9 in the direction of the inlet opening 4 when the closure device 1 is in the closed state, the inner seal 21in precisely this stateabutting in a sealing manner against an inner surface of the basic member 2 pointing towards the closure axis 50 in order to seal the channel 3 in a liquid-tight manner even when the sealing membrane 19 also shown here has been removed.

[0087] The second embodiment shown in FIGS. 6 to 10 differs from the first embodiment shown in FIGS. 1 to 5 only with regard to the geometry of the weakening lines and with regard to the design of the first and second guiding means. Therefore, only these differences will be discussed below. The remaining features and advantages of the second embodiment shown in

[0088] FIGS. 6 to 10 correspond to the features and advantages already described for the embodiment shown in FIGS. 1 to 5.

[0089] In particular, it can be seen in FIG. 6 that in the second embodiment, a first holding band 123 and a second holding band 124 are also characterised by a first weakening line 125 and a second weakening line 126. In contrast to the first embodiment, however, the two weakening lines 125 and 126 in this case always extend axially spaced apart from one another, each of the two weakening lines 125 and 126 being interrupted by a separating web. As a result, two symmetrically connected holding bands 123 and 124 are formed after the weakening lines 125 and 126 are torn. This means that the connection points of the two holding bands 123 and 124 to the anchor ring 12 are both at essentially the same distance from the closure cap 8.

[0090] The second weakening line 126 has a bulge projecting towards the inlet opening 4 in the area of the separating web of the first weakening line 125. As a result, the separating web of the first weakening line 125, which forms the fixing element 18, extends further in the direction of the inlet opening 4 than the connection points between the respective holding bands 123, 124 and the anchor ring 12. This advantageously causes the fixing element 18 to abut particularly firmly against the support ring in the second position. In other words, there is a stronger latching between the support means 14 and the fixing element 18namely due to the axially elongated design of the fixing element 18 in the direction of the inlet opening beyond the axial position of the connection points between the holding bands 123, 124 and the anchor ring 12.

[0091] The embodiment shown in FIGS. 6 to 10 also differs from the embodiment shown in FIGS. 1 to 5 in that the first and second guiding means 6, 11 configured as external and internal threads are shorter in the circumferential direction, namely such that the external and internal threads are disengaged after the closure cap has been rotated by approximately 60 degrees from the fully closed position.
