DESCRIPTION

Closing device with an anchor ring and a guarantee ring, and method of its manufacture

The present invention relates to a closure device for closing a container, a semi-finished product for a closure device and a method for manufacturing a closure device.

From document WO 2022/029110 A1, an aseptic closure device connected according to the preamble of claim 1 is known. From document WO 2022/029110 A1, a closure device is also known which discloses the characteristics of the semi-finished product according to the preamble of the claim>2<.>

A screw cap of a plastic rotary closure is known from document WO 2020/178012 A1.

Closing devices for containers are known from EP 3805 126 A1, which have a closing lid, an anchoring ring and a securing ring, the anchoring ring being permanently connected to the closing lid via a band. of connection. The durable connection with the anchoring ring ensures that the closure cap is not lost when used by a consumer of the container equipped with the closure device and does not end up in the environment as unwanted waste. The guarantee ring also represents a guarantee insurance that is clearly visible and known to the consumer.

However, in these closure devices described in the state of the art, tearable ribs are always arranged both between the anchor ring and the guarantee ring, and between the closure cap and the anchor ring. Although the ribs between the anchor ring and the retaining ring can be broken with a simple twisting motion, the consumer must use force to break the ribs between the anchor ring and the closure cap. The tearing force is usually too high for a comfortable and easy opening.

The placement of tearable ribs between the anchor ring and the guarantee ring is absolutely necessary, since precisely this provides guarantee security.

However, as additional security insurance, the placement of easily torn ribs between the anchoring ring and the closure cap is not absolutely necessary.

Against this background, an object of the present invention is to provide a closure device with a closure cap attached to an anchor ring that allows simplified opening.

Figures 1 and 2 show a semi-finished product 100 according to the invention, which also comprises a base element 14 providing a pouring channel 15 and a cutting device 18 arranged in the channel 15. The intermediate product shown does not yet represent a closing device>1<completed, i.e. capable of functioning, since>the closing cover 2 is attached to the anchoring ring 5 through the non-tearable rib 101, so that a relative axial movement of the closing cover 2 and the anchoring ring 5 - in order to release the pouring opening 17 of the channel 15 - is not possible for a consumer without great effort or without the use of tools.

In Figure 2 you can see the connecting element 7 made as a hinge. However, in the state shown here, the non-tearable rib 101 prevents a tilting movement from being performed. As soon as the non-tearable rib>101< has been cut, a tilting of the closure cover>2< is possible, at least for the relative angular position of the closure cover 2 with respect to the base element 14, in which the guide means 9 of the skirt <of lid 4 and the guide means 10 of the closing base>8<made as a base element 14 allow such a tilting rotation movement. In the representation shown here you can also clearly recognize the tearable ribs 11 that join the guarantee ring 6, arranged axially below the anchor ring 5, with the anchor ring 5.

Figure 3 shows a cross-sectional view of the semi-finished product 100 with respect to a cutting plane that cuts both the hinge and the non-tearable rib 101. The anchor ring 5 is fixed with respect to the base element 14 by retaining elements>21<which are directed radially inwards and axially towards the closing cover>2<and made as tabs, the retaining elements>21<being applied to a retaining ring>22 of the base element 14 circumferential, that is, it extends through a circumferential angle of 360 degrees and runs perpendicular to the closing axis 50. The cutting device is shown here in its starting position, in which the cutting elements 19 are still completely within the channel 15 defined by the base element 14, through which in the driving element 20' arranged in the closing cover 2 when the closing cover is rotated>2<- as soon as this is possible also after of a cut of the non-tearable nerve>101 - a movement of the cutting elements 19 in the direction of the entrance opening 16 of the channel 15 is initiated.

The semi-finished product 100 shown in Figure 3 furthermore has guide means 9 on the lid skirt 4 of the closing lid 2 and corresponding guide means 10 on the base element 14, which are designed as bayonet elements. The bayonet element of the closing cap 2 is a projection projecting radially inward on the lid skirt 4 and the bayonet element of the base element 14 is an annular element projecting radially outward from the base surface of the outer surface of the channel 15 and which does not extend completely through the 360 circumferential angle, but in a certain angular position not shown here presents an interruption, so that in this angular position the projection of the lid skirt 4, which protrudes radially inwards and is made as guide means 9 and the annular element that protrudes radially outwards are decoupled. This certain angular position can be achieved by a rotation of the closure cover 2. As long as the non-tearable rib 101 is intact, also in this angular position a tilting of the closure cover 2 and a release of the inlet opening 16 is prevented. that it carries. As soon as the non-tearable rib>101<has been cut, a tilting of the closure cover>2 is possible<exclusively>in this angular position of the closure cover 2 and the base element 14.

In the embodiment shown here, both the guide means 9 of the lid skirt (projection) and the guide means 10 of the base element 14 (ring element) extend in the circumferential direction in a plane perpendicular to the axis of closure 50, so that with a rotation of the closure cover 2 and the anchoring ring 5 connected to it at least as long as no relative axial movement is carried out between the closure cover>2<and the base element>14 the two guide means 9 and 10 are applied to each other.

Figure 4 shows a closure device 1 according to the invention that is obtained by cutting the non-tearable rib 101 (101'). A state of the locking device 1 is shown here, as it appears after a consumer has opened the locking device 1 for the first time. By means of an opening rotation movement for the first time, stop elements located radially inside the guarantee ring >6<, which are initially not>visible here, engage with corresponding stop elements of the base element 14, so that <a joint rotation movement of the guarantee ring>6<is blocked with the anchoring ring 5 and the closing cover 2. Due to the>gravitational forces that are formed, the tearable ribs 11 are caused to enter the anchor ring 5 and <guarantee ring>6<tear (break).>

In Figure 4, the torn tearable ribs 11' can be clearly recognized. After this tearing of <the tearable ribs 11 - as shown here - the guarantee ring>6<separates from the anchor ring 5, leaving the guarantee ring>6<still on the base element 14. Therefore , the consumer can clearly recognize that an opening rotation movement has taken place for the first time. After separating the securing ring >6<, the closing device >1<can be moved without great additional efforts to the state shown here, in which the >closing cover 2 is tilted slightly upwards. To do this, the closing cover 2 must be rotated to the angular position in which the guide means 9 of the cover skirt 4 of the closing cover 2 and the guide means 10 of the base element 14 are disengaged. In the form embodiment shown here, this angular position is chosen in such a way that in this angular position the cutting element 19 was moved maximally in the direction of the inlet opening or partially also through the inlet opening 16 by the device of drag>20<(which here>consists exclusively of a drag element 20'). As soon as this angular position has been reached, the consumer can tilt the closing lid 2 on the hinge and thus release the pouring opening 17 - and all without having to break a series of tearable ribs again.

The first embodiment of the semi-finished product 100 according to the invention shown in Figures 1, 2 and 3 differs from the first embodiment of the closing device 1 according to the invention shown in Figure 4<exclusively in that in the closing device closure>1<according to the invention, the non-tearable rib>101<is cut,>while this is still intact in the embodiments according to Figures 1,2 and 3.

<The second embodiment of the semi-finished product 100 according to the invention shown in Figures 5,>6<and 7>differs from the first embodiment of the semi-finished product 100 according to the invention shown in Figures 1, 2 and 3 exclusively in that on the lower edge of the lid skirt 4 there are additionally provided two projections 12<that extend axially in the direction of the guarantee ring>6<, each of which is arranged in a correspondingly made recess 13 of the anchoring ring 5. The characteristics and advantages described above of the first embodiment shown in Figures 1, 2 and 3 are therefore also valid for the second embodiment of the semi-finished product 100 according to the invention. The same reference symbols are used for the same or similar elements. Only the differences are described below.

The two projections 12 arranged on the lid skirt 4 have a basic triangular shape, the <projections>12<being made speculatively symmetrical to each other with respect to a plane that passes centrally through the hinge and that>contains the closing axis. The shape of the recesses 13 of the anchoring ring 5 is also triangular. In the front view shown in Figure 5, the projections 12 resemble the canine teeth of a vampire or the fangs of a young walrus. In combination, the projections 12 and the recesses 13 allow the transmission of a turning moment from the closing cover 2 to the anchoring ring 5, or also vice versa from the anchoring ring 5 to the closing cover 2. This is particularly advantageous for closing devices 1 with large diameters, since often the transmission of the turning moment through the hinge is insufficient to ensure a sufficiently good joint rotation of the anchoring ring 5 and the closing cover 2 during the movement of opening rotation or closing rotation movement.

<The second embodiment of the closure device 1 according to the invention shown in Figure>8<results from the cutting of the non-tearable rib>101<of the second embodiment of the semi-finished product>100<according to the>invention. This embodiment of the closure device 1 according to the invention differs from the embodiment shown in Figure 4 also only with respect to the combinations of projection and recess described. Therefore, all statements relating to the first embodiment shown in Figure 4 are <also valid for the second embodiment of the closure device>1<according to the invention shown in Figure>8<.>

Figures 9 to 13 show the different stages of a semi-finished product 100 or a closure device 1 during a manufacturing method according to the invention and the subsequent intended use.>

Figure 9 shows as a starting point a third embodiment of a semi-finished product 100 according to the invention, the semi-finished product 100 being shown in a state in which it is immediately after injection molding. In the embodiment shown here, two diametrically opposed non-tearable ribs 101 are provided, which are respectively designed as axially extending stirrups and connect the radially outer side of the lid skirt 4 to the radially outer side of the anchoring ring 5. In <this representation illustrating the immediate state after injection molding, the retaining means>21 made as tabs are also still in a position oriented radially towards the<guarantee ring>6<.>

The third embodiment of a semi-finished product 100 according to the invention or of a closure device 1 according to the invention shown in Figures 9 to 13 differs from the first embodiment of a <semi-finished> product 100<according to the invention or of a closure device>1<according to the invention essentially in the embodiment>of the non-tearable ribs 101. Therefore, the same reference numbers are used for the same or similar elements.

In a step of the manufacturing method that follows injection molding, the result of which is represented in Figure 10, the retaining means of the anchor ring 5 made as tabs are folded, so that they are aligned in the direction of the cover closure>2<and can therefore be applied to a retaining ring>22<of a>base element 14, whereby the anchoring ring 5 is fixed with respect to the base element 14 in the axial direction.

In another step, the non-tearable nerves 101 formed as stirrups are cut. The result of this cutting is represented in Figure 11. The semi-finished product 100 has now become a functional closure device 1. It is now easier for the consumer to use the closure device 1, since the tearable ribs <11 are located exclusively between the anchoring ring 5 and the guarantee ring >6<, where they are absolutely>necessary.

<The embodiments of semi-finished products 100 and closure devices 1 shown in Figures 1 to >8<and>12 and 13 are all made for aseptic beverage cartons in which the closure device 1 cuts into the opening of pouring when first opened. Therefore, they all contain a base element 14, a driving device and a cutting device 18.

In principle, a semi-finished product 100 according to the invention (as shown in Figures 9 and 10, only without a driving element 20') or a closure device 1 according to the invention (as shown in Figure 11<, only which without a driving element>20<') can also be used for cardboard beverage containers with>closing devices applied from the inside, which are used above all for fresh products.

Figure 12 now shows the result of an assembly step in which the closure device 1 of Figure 11 is expanded with other components, namely a base element 14 and a cutting device 18, so that as a result an aseptic closure device 1. This can now be placed, for example, on a cardboard container, so that, as shown in Figure 13, by means of an opening rotation movement of the closing lid 2 together with the anchoring ring 5, the guarantee ring>6<due to breakage of the tearable>ribs 11 and the cutting element 19 passes through the entry opening and therefore an opening is generated in the cardboard packaging material or a sealing surface provided for it, through from which bulk material can then be poured from the carton through channel 15.

In Figures 9 to 11 you can also see stop elements 23 located radially inside the <guarantee> ring 6<. In case of an opening rotation movement of the closure device 1 shown in Figure 11, these can engage with corresponding stop elements (shown here not visible) and produce a breakage of the tearable ribs 11 due to the forces of shear that occur.>

In Figure 12, a sealing ring 24 can also be recognized, which is arranged on the lid cover 3. In an assembled state with the base element 14, this sealing ring 24 is applied to the inner surface of the channel 15 of the element. base 14 and thus seals the pouring opening 17 in the closed state of the <closing>1< device.>
