Description

[0001] DESCRIPTION

[0002] CONTAINER CLOSURE

[0003] The invention relates to a container closure according to the features of the respective preamble of the two independent patent claims.

[0004] DE 10 2014 207 652 A1 discloses a container closure (1) comprising a closure base (5) and a cap (2), as well as a mouthpiece (3) and means for piercing a closure film. A tamper-evident band (6) is provided to ensure that the closure film can only be pierced by the means once the tamper-evident band (6) has been removed. The tamper-evident band (6) is arranged between the closure base (5) and the cap (2). The reference numbers refer to the aforementioned document.

[0005] Furthermore, DE 10 2017 100 184 A1 discloses a container closure (1) comprising a closure lower part (5) and a cap (2), as well as a mouthpiece (3) and means for piercing a closure film, wherein a tamper-evident strip (6) is provided which ensures that the closure film can only be pierced by the means once the tamper-evident strip (6) has been removed, wherein the tamper-evident strip (6) is arranged between the closure lower part (5) and the cap (2), wherein the tamper-evident strip (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 lower part (5) in sections such that it can be rotated and pressed. The reference numbers refer to the above-mentioned document.

[0006] The invention is based on the object of improving a known container closure with a tamper-evident band (sealing ring) with regard to its handling and environmental compatibility. This object is achieved in that the tamper-evident band has several predetermined breaking points aligned in the axial direction of the container closure and is actuated by a spreading process. Before the predetermined breaking points are separated, it is clearly visible and verifiable that the tamper-evident band has not yet been actuated, i.e., that the container closure is still intact. When actuated, the predetermined breaking points, which are distributed over the circumference of the container closure, are separated by a simple press, making the container closure easy to handle.After pressing, the guarantee band press-fits against the container closure and remains in place, so that all parts can be disposed of together, and in particular recycled, without individual parts of the container closure being lost and polluting the environment.

[0007] 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, with the rotation, the guarantee strip is spread. Once this has happened, it is possible for the cap to be pressed down towards the container to which the container closure is attached, in particular screwed, in order to actuate the means for piercing the sealing film. This makes it possible for an additive arranged in the lower part of the closure to be released and to move towards the container. On the other hand, it is conceivable that the cap is first unscrewed from its original state without the guarantee strip being spread. The guarantee strip is only spread when the cap is pressed down towards the container in this state.

[0008] In a simpler version of the two variants mentioned above for actuating 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 actuated, i.e. opened, independently. If the cap initially remains in its original state (as delivered), it is possible to open the mouthpiece cover without turning the cap. 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 allows the additive contained in the lower part of the closure to enter the container, the surface area for actuating the piercing means is relatively small, meaning that greater 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 activated, 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 (as delivered) to a further position, which simultaneously causes the means for piercing the sealing film to be moved along with this movement. Since this movement involves pressing the cap down towards the container, the free surface of the mouthpiece cover means a larger area is available to actuate this movement, so that less force is required to actuate the means for piercing the sealing film.After the means for piercing the sealing foil have been activated, the additive contained in the lower closure part is released into the container. At the same time, the means for piercing remain in this depressed position within the lower closure part, so that the contents of the container, mixed with the additive, can be removed through the lower closure part along the means for piercing the sealing foil via the mouthpiece, and preferably drunk. The cap also remains in a position on the lower closure part that differs from the delivery state. In this position, the broken predetermined breaking points are clearly visible and indicate that the container closure has already been activated.By operating the mouthpiece cover, it is possible to close the mouthpiece again (as was the case in its original state) or to open it and then close it again at any time. The mouthpiece cover also advantageously remains on the cap so that this container closure unit, consisting of the lower closure part, cap and means for piercing the sealing film, remain together and can be recycled together. In this case, the regulation for so-called "tethered caps" is met. If this is not necessary, these components can also be arranged so that they can be detachably arranged and thus separated from one another. In this case, they can be recycled separately.

[0009] In a further development of the invention, the lower closure part has at least one web arranged approximately in its central region and pointing outwards, wherein the at least one web interacts with a predetermined breaking point of the tamper-evident strip. The at least one web causes the circumferential tamper-evident strip to widen when the latter is rotated manually relative to the lower closure part. The at least one web lies in a recess of the tamper-evident strip in the region of the predetermined breaking point, so that the material of the tamper-evident strip is continuous there but somewhat thinner than the surrounding areas. As a result of the rotation, the web is moved out of this recess and causes the tamper-evident strip to spread (widen), with the result that the thinner region of the predetermined breaking point breaks upon further rotation, which can be visually detected from the outside.In addition, the cap is designed in such a way that it cannot be pushed down towards the container until at least one predetermined breaking point has been broken.

[0010] In a further development of the invention, several webs are provided distributed around the circumference of the closure base. This increases visibility as to whether the tamper-evident strip has been activated or not, i.e., whether the predetermined breaking points have been breached. Furthermore, this enhances the security of the tamper-evident strip, as several predetermined breaking points must be breached before the cap can be pressed down relative to the closure base. Furthermore, the forces when rotating the cap relative to the closure base are reduced in this case, as the material in the area of ​​the predetermined breaking points can be made thinner than if only a single predetermined breaking point were present.

[0011] In a further development of the invention, the web is aligned parallel to the vertical axis of the container closure. Accordingly, the recess in the tamper-evident strip for forming the predetermined breaking point is also aligned parallel to the vertical axis of the container closure. As a result, the cap, in its as-delivered state, rests securely against its lower closure section, and significant force is required to twist the cap and thus spread the tamper-evident strip. For the person operating the container closure, this creates not only a visually perceptible effect, but also a tactilely perceptible effect that the tamper-evident strip has been spread and thus the container closure has been activated.

[0012] In an alternative embodiment, the invention further provides for the web to be oriented at a different angle to the vertical axis of the container closure. Such an oblique arrangement of the web on the closure base and the corresponding oblique alignment of the recess in the tamper-evident strip to form the predetermined breaking point reduce the forces required to twist the cap relative to the closure base, while simultaneously maintaining the visibility of the broken predetermined breaking point(s) after this twisting. The tactile effect of the tamper-evident strip being spread and thus the container closure being actuated is thus retained, albeit to a somewhat lesser extent.

[0013] As an alternative to designing the lower closure part with webs which cause the tamper-evident strip to spread when the cap rotates, the invention provides that the lower closure part has, above its fastening area, a central region which tapers conically towards the mouthpiece. In the delivered state of the container closure, the tamper-evident strip is cylindrical, as in the alternative described above, and has at least one predetermined breaking point, preferably several distributed predetermined breaking points, along its circumference. By pressing the cap down towards the container, this initially still cylindrical region of the tamper-evident strip slides over the central region of the lower closure part which widens conically towards the bottom, causing the tamper-evident strip to spread and the predetermined breaking points to break open.When the cap is pressed down with the mouthpiece closed (the mouthpiece cover not actuated), the means for piercing the sealing foil are also taken along. However, it could be considered to first open the mouthpiece cover, actuate the means for piercing the sealing foil, then close the mouthpiece cover again, and only then push the cap down over the conically widening area to spread the tamper-evident band and break open the predetermined breaking points. This provides at least one further design for spreading the tamper-evident band by pressing it down.

[0014] In a further development of the invention, the closure lower part has, above its fastening area, at least one at least partially, preferably completely, circumferential support surface that interacts with a contact surface of the cap, preferably the circumferential lower edge of the tamper-evident strip. This interaction has the advantage that, in the as-delivered state, high loads can act on the cap from above without the tamper-evident strip spreading. This ensures a high so-called "top load" in the event that several containers with mounted container closures according to the invention are placed on top of one another, as is common, for example, during storage or sale of such containers.Alternatively, or preferably in addition, the interaction has the advantage that the bearing surface on the lower closure part brings about a contact and thus limits the movement of the cap relative to the lower closure part after the tamper-evident band has been spread and the cap has been pressed down relative to the lower closure part. If bearing surfaces are present on the lower closure part and corresponding contact surfaces on the cap, it goes without saying that spreading the tamper-evident band removes the contact of those surfaces that cause the "top load," since otherwise, pressing the cap down relative to the lower closure part would not be possible.At the same time, the design ensures that after pressing down, the contact surface of the cap, in particular the lower circumferential edge of the guarantee band, comes into contact with the corresponding contact surface on the lower part of the closure and thus further pressing down is no longer possible.

[0015] In a further development of the invention, it is provided that the lower closure part has at least one latching connection, wherein the cap also has at least one latching connection that interacts with the latching connection of the lower closure part. These mutually corresponding latching connections ensure that the cap is held in a respective desired or required position in relation to the lower closure part. Since these latching connections are releasable, it is possible for the cap, which is initially held in one position, to be brought into at least one further position or precisely one different position after the at least one latching connection has been released. This ensures, for example, that the cap is held in an upper position on the lower closure part in the delivery state and that after the cap has been actuated (in particular by pressing down) it is held again in a position below the upper position.This has the advantage that the cap is held in its respective position relative to the closure base and can no longer be moved up and down. Furthermore, it prevents the cap from becoming detached from the closure base, as in the case of a "tethered cap." The corresponding locking connections can be designed, for example, as a circumferential groove (in the closure base) and a circumferential web (facing inward in the interior of the cap), or vice versa, or the like. A further development of the invention provides for the mouthpiece cover to be attached to the cap via a film hinge. This allows the mouthpiece cover to be easily manufactured and attached to the cap in a cap-locking manner using an injection molding process. At the same time, the mouthpiece cover can be easily opened and closed.

[0016] In a further development of the invention, the mouthpiece cover is arranged on the cap via at least one predetermined breaking point. As with the at least one predetermined breaking point on the tamper-evident strip, the predetermined breaking point between the mouthpiece cover and the cap can be used to visually determine whether the container closure is in its as-delivered state (unopened) or whether it has already been used (broken predetermined breaking point between the cap and the mouthpiece cover). It is also conceivable to provide only one predetermined breaking point or several predetermined breaking points instead of the film hinge. In this case, however, the mouthpiece cover cannot be reattached, making resealing impossible.

[0017] In a further development of the invention, the mouthpiece cover is connected to the cap via at least one snap-in connection that can be released by an external force. The snap-in connection between the mouthpiece cover and the cap is designed in such a way that it cannot be released manually using normal force. Only when the snap-in connection is manually actuated from the outside using an additional actuating element can it be released, and then the mouthpiece cover can be detached from the cap or opened.

[0018] Regardless of the functionality of the container closure, the closure base can be formed as a single piece or assembled from at least two parts. An exemplary embodiment of the invention is described below with reference to Figures 1 to 7.

[0019] Figure 1 shows a container closure 10 in the invention, which has a lower closure part 11, a cap 12 movably arranged above it, and means 13 for piercing a sealing film (not shown). An additive is filled into the lower closure part 11 within and partially around the means 13, the lower closure part being sealed in its lower region with a sealing film. The lower region of the lower closure part 11 is provided, for example, with a thread and can be arranged or is arranged on a container (not shown) into which a medium is or can be filled, in the case of the thread, screwed onto it. For the defined fixing of the cap 12 to the lower closure part 11, the lower closure part 11 has at least one snap-in connection, wherein the cap 12 also has at least one snap-in connection that interacts with the snap-in connection of the lower closure part 11.These two cooperating snap-in connections are released or separated from each other when the cap 12 has been pressed down in the direction of the container relative to the closure base 11 (see Figure 5 later).

[0020] Figure 2 shows the three elements of the container closure 10 in detail. The lower closure part 11 has, as can be seen in the left-hand illustration, a fastening area 14 with which the lower closure part 11 is arranged on the container, preferably screwed on. In the other end area facing away from this, a mouthpiece 15 is provided which, when viewed in Figure 2 (left-hand illustration), does not have an opening. Between the two end areas of the lower closure part 11, the latter has a central area 16. Along the course of the central area 16 (when viewed from top to bottom), there is at least one circumferential shoulder, preferably two circumferential shoulders 17.1 and 17.2. Also arranged in the central area 16 is a web 18 aligned approximately parallel to the vertical axis of the lower closure part 11. In this exemplary embodiment, there are several webs 18 distributed over the circumference.

[0021] The central illustration of Figure 2 shows the means 13 for piercing the sealing film. The upper end of this means 13 can be pressed, whereby by pressing downwards (when viewing Figure 2 from top to bottom), the lower end of the means 13 breaks through the sealing film (not shown) and thus opens it, allowing the additive contained within the lower closure part 11 to flow into the container below.

[0022] The right-hand illustration in Figure 2 shows the cap 12, which, as can be seen in Figure 1, is arranged over the upper part of the closure base 11 in the delivery state. The cap 12 also has a central region 19, above which is arranged a movable mouthpiece cover 20 and below which is arranged a tamper-evident band 21. These elements form the cap 12 in one piece, but optionally also movable (mouthpiece cover 20). The tamper-evident band 21 contains at least one predetermined breaking point 22. In practice, several predetermined breaking points 22 are distributed around the circumference of the tamper-evident band 21. At least one predetermined breaking point 22 is not yet broken in the delivery state, as can also be seen in Figure 1. The mouthpiece cover 20 is connected to the central region 1, preferably via a film hinge 23.To document that the mouthpiece cover 20 has not been actuated in the delivery state, a predetermined breaking point 24 is provided. This predetermined breaking point 24 is broken when the mouthpiece cover 20 is actuated via the film hinge 23, i.e., opened to make the mouthpiece 15 of the closure lower part 11 accessible.

[0023] Figure 3 shows how the cap 12 must be moved, starting from the delivery state, so that this movement spreads the guarantee strip 20. By a rotational movement D of the cap 12 relative to the lower closure part 11, the guarantee strip 21 slides over the webs 18 of the lower closure part, so that the guarantee strip 21 is spread. The rotational movement D can be limited by corresponding stops between the lower closure part 11 and the cap 12, but this does not have to be the case. After this rotational movement D has been carried out, it is possible that the cap 12 can be pressed down in the direction of the container (not shown) by exerting a force from top to bottom, as viewed in Figure 3.

[0024] Figure 4 shows the function of the tamper-evident strip 21 in detail. When looking at the left-hand illustration in Figure 4 and the enlarged illustration in the middle, it can be seen that there are recesses all around the tamper-evident strip 21 into which the webs 18 of the lower closure part 11 come to rest in the as-delivered state when the cap 12 was arranged on the lower closure part 11. In this state, the predetermined breaking points 22 are not yet opened. If the rotary movement D occurs, i.e. the rotary movement caused by the action of a force from the outside of the cap 12 around the lower closure part 11, the webs 18 are transferred from the thinner area of ​​the tamper-evident strip 21 to the thicker area of ​​the tamper-evident strip 21, whereby a spreading S of the tamper-evident strip 21 occurs. This spreading leads to a breaking open of the predetermined breaking points 22 due to the thinner material thickness of the tamper-evident strip 21.This means that the tamper-evident band 21 breaks open and spreads, since the webs 18 are preferably conical. The upper connection of the tamper-evident band 21 to the central region 19 of the cap 12 acts as a hinge, which is clearly visible in the right-hand illustration of Figure 4.

[0025] After the cap 12 has been rotated relative to the closure base 11 and the guarantee band 21 has been spread, it is possible to push the cap 12 down by a movement K, which is shown in Figure 5.

[0026] In this regard, the following should be noted regarding the arrangement and sequence of movement of the cap 12 in the direction of the container. In the delivery state, as shown in Figure 1, the circumferential lower edge of the tamper-evident band 21 rests on the circumferential shoulder 17,2 of the closure bottom part 11. This means that the cap 12 is supported on the closure bottom part 11 in the delivery state and it is prevented that the cap 12 can move downwards in this state. This ensures the required "top load 1' is realized. This contact of the lower edge of the guarantee strip 21 with the circumferential shoulder 17.2 is then released when the cap 12 is rotated and the guarantee strip 21 has been spread (see Figure 3). Only by releasing the contact is it possible for the cap 12 to be pressed downwards. In order to stop the downward movement of the cap 12 in a defined manner, the further circumferential shoulder 17.1 is provided in the transition between the fastening area 14 and the central area 16 of the lower closure part 11. If the cap 12 is pressed down in the direction H as shown in Figure 5, the circumferential lower edge of the guarantee strip 21 ultimately comes to rest on the circumferential shoulder 17.1 so that further pressing down is no longer possible.

[0027] Alternatively, the cap has ribs which, after being spread and pressed down, rest on the heel 17.2, which also stops the movement.

[0028] This completion of the movement of the cap 12 causes the activation of the container closure 10, since the means 13 for piercing the closure film are also moved axially downwards by the downward pressure, which results in the opening of the closure film. As a result, the additive in the lower closure part 11 reaches the container below, not shown.

[0029] After this activation of the container closure 10 has taken place, the additive can mix with the medium in the container and be removed. This removal enables the design of the container closure 10 as shown in Figure 6. The guarantee band 21 remains in the position shown, whereby the mouthpiece cover 20 arranged on the central region 19 of the cap 12 can be actuated, i.e. opened. The predetermined breaking point 24 is broken by the application of an external force, for example by means of the hand, and the mouthpiece cover 20 can be pivoted by means of the film loser 23, whereby the mouthpiece 15 of the lower closure part 11 becomes accessible. Since the mouthpiece 15 is open in its upper end region after the means 13 have been pressed down, the medium can be removed from the container, for example, to be drunk.

[0030] Figure 7 shows the case in which the medium in the container has not yet been completely emptied, in which case the mouthpiece cover 20 is folded back over the film hinge 23, thus closing the opening in the mouthpiece 15. The remaining parts of the cap 12, as well as the means 13, no longer move. To ensure this, the lower closure part 11 has at least one locking connection, with the cap 12 also having at least one locking connection that interacts with the locking connection of the lower closure part 11. By pressing down in direction H, these two locking connections are connected to one another, so that the cap 12 is secured to the lower closure part 11 in the pressed-down state.

[0031] With the design of the container closure 10 shown in Figures 1 to 7 and its corresponding mode of operation, the tamper-evident strip 21 can, but need not, be provided in such a way that the sealing film can only be pierced by the means 13 once the tamper-evident strip 21 has been activated. It is fundamentally also possible to open the mouthpiece cover 20 so that the upper end of the means 13 is exposed, and then, or not at all, to rotate the cap 12 around the closure base 11 so that the tamper-evident strip 21 is spread. During this spreading process, the means 13 are not yet activated; this only occurs when the cap 12 is pressed down toward the container or independently of it. The latter is possible because, when the mouthpiece cover 20 is open, the means 13 are not automatically carried along by the cap 12 when it is pressed down.

[0032] By pressing on the free-standing and thus protruding upper region of the means 13, for example with a finger, the film can be pierced after the mouthpiece cover 20 has been opened, even without twisting the cap 12 and activating the guarantee strip 21. The illustrations in Figure 8 show a sequence of movements for actuating an alternative container closure, corresponding to the embodiments shown in Figures 1 to 7. In addition to similar elements and their similar movement, in the embodiment of the container closure shown in Figure 8, the lower closure part 11 has, above its fastening region 14, a central region 16 that tapers conically in the direction of the mouthpiece 15. In this embodiment, the guarantee strip 21 is spread by pressing the cap 12 downwards, as viewed in Figure 8, i.e. in the direction of the container on which the container closure is arranged.The conical downward widening of the central region 16 breaks open the predetermined breaking points 22 of the tamper-evident strip 21. Before the cap 12 can be pressed downward, it is necessary, as shown in the two lower left illustrations of Figure 8, for the cap 12 to be rotated from a first position (as delivered) to a further position, for example, by approximately or exactly 90 degrees, before the cap 12 can be pressed down. This serves to secure the container closure against unintentional pressing down (and thus actuation of the means 13) and is an externally recognizable sign of an unactuated (and thus new, unused) container closure. This turning process preferably takes place before pressing down, although the turning process can alternatively be omitted, so that the cap 12 can be pressed down directly without prior rotation to spread the tamper-evident strip 21 and actuate the means 13.

[0033] Figures 9 to 11 show 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 snap-in connection which can be released by an external force.

[0034] This embodiment is an alternative to the arrangement of the mouthpiece cover 20 on the cap 12, wherein here, instead of the predetermined breaking point 24, a locking connection is provided which can only be released by applying a force from the outside, so that this release of the locking connection enables the opening of the mouthpiece cover 20, ie, a pivoting around the film hinge 23 or another type of opening.

[0035] In the initial state, particularly the delivery state, the mouthpiece cover 20 is arranged in a first position, which is shown in Figure 9, on the upper region of the cap 12. On the one hand, the mouthpiece cover 20 is fastened via the film hinge 23. However, the actuation of the mouthpiece cover 20 by pivoting about the film hinge 23 is only possible when the locking connection, formed by a locking hook 25 on the mouthpiece cover 20 and a further corresponding locking hook 26 on the cap 12, is released by the application of an external force. So that the externally acting force can release the locking connection, a projection 27, for example designed as a bead, is arranged on the lower closure part 11 as an additional actuating element, and a corresponding bevel 28 is arranged on the cap 12.The projection 27 and the bevel 28, which can be brought into operative connection with it, are arranged either completely or partially circumferentially on the closure base 11 or the cap 12. They can also be present in multiple circumferential locations, interrupted by non-corresponding and operatively connected areas.

[0036] Figure 9 shows that the two locking hooks 25, 26 are operatively connected to one another, so that it is not possible to actuate the mouthpiece cover 20, in particular to pivot it open around the film hinge 21 so that the mouthpiece 15 would be made accessible.

[0037] This state is shown again in detail in Figure 10. It can be seen that the cap 12 has a thicker wall thickness below its locking hook 26, which tapers along a slope 28 to a lower material thickness of the cap 12 at the level of the projection 27. The slope 28 is shown as stepped in Figure 10. Alternatively, it can also be curved. If an external force is applied to the cap 12, more precisely to the surface of the mouthpiece cover 20, this causes the cap 12 to move downwards as viewed in Figures 9 and 10. By pressing downwards in the direction of the container (not shown), the slope 28 reaches the projection 27, i.e.that the area of ​​the cap 12 with the initially thinner wall thickness slides along the projection 27 of the lower closure part 11 and reaches the area of ​​the cap 12 with the then thicker wall thickness, so that the area of ​​the cap 12 widens in the area of ​​the locking connection 25, 26. This widening causes the upper part of the cap 12 in the area with the locking hook 26 to move away (lift off) from the locking hook 25 of the mouthpiece cover 20, as shown in Figure 11. In this state, the locking connection 25, 26 is released, so that it is possible to move the mouthpiece cover 20 and thus make the mouthpiece of the lower closure part 11 accessible.

[0038] In the embodiment illustrated in Figures 9 to 11, the locking connection 25, 26 is present only over a small portion of the circumference of the cap 12 or the mouthpiece cover 20, respectively, and preferably opposite the film hinge 23. Alternatively, however, it is conceivable to provide not just one partially circumferential locking connection, but rather several partially circumferential locking connections between the cap 12 and the mouthpiece cover 20. In this case, the film hinge 23 can be omitted entirely, particularly if the locking connection 25, 26 is provided over the entire circumference or multiple times over the partial circumference (interrupted by partial circumferences without a locking connection) on the cap 12 and correspondingly on the mouthpiece cover 20.
