Description

Technical Field

[0001] The present invention relates to a container closure according to the features of the respective preambles of the two independent claims. Background Technology

[0002] A container closure (1) is known from DE 10 2014 207 652 A1, having a lower closure component (5), a cap (2), a mouth component (3), and a mechanism for piercing the closure membrane, wherein an tamper-evident ring (6) is provided, which ensures that the mechanism can pierce the closure membrane only after the tamper-evident ring (6) is removed, wherein the tamper-evident ring (6) is arranged between the lower closure component (5) and the cap (2). Reference numerals are based on the aforementioned document.

[0003] Furthermore, a container closure (1) is known from DE 10 2017 100 184 A1, having a lower closure component (5), a cap (2), a mouth component (3), and a mechanism for piercing the closure membrane, wherein an tamper-evident ring (6) is provided, which ensures that the mechanism can pierce the closure membrane only after the tamper-evident ring (6) is removed, wherein the tamper-evident ring (6) is arranged between the lower closure component (5) and the cap (2), wherein the tamper-evident ring (6) is configured as a closure ring, which is connected to the lower edge of the cap (2) by at least one separable rib (8), and the cap (2) is rotatably and pressably supported on the lower closure component (5) in segments. Reference numerals are based on the aforementioned document. Summary of the Invention

[0004] The purpose of this invention is to improve the operability and environmental compatibility of a known container closure with an anti-tampering ring (sealing ring).

[0005] This objective is achieved by having the tamper-evident band (or break-point tamper-evident band) have multiple predetermined break points oriented along the axial direction of the container closure, and being operated / activated through an expansion process. Before the predetermined break points are broken, it is visually clear that the tamper-evident band has not been operated; that is, the container closure remains intact. Operation or activation involves simply pressing to break the predetermined break points distributed on the outer periphery of the container closure, thus facilitating its operation. After pressing, the tamper-evident band presses against and remains on the container closure, allowing all components to be disposed of together, particularly recycled, without the loss or environmental pollution of individual components.

[0006] The expansion process can also be carried out in several ways. On one hand, the cap can be unscrewed from its initial state, and the tamper-evident ring can be expanded by this rotation. After this process is complete, the cap can be pressed downwards towards the container with (especially with) the container closure to operate the mechanism for piercing the closure membrane. Thus, the additive contained in the component below the closure can be released and moved towards the container. On the other hand, the cap can be unscrewed from its initial state without expanding the tamper-evident ring. The tamper-evident ring is only expanded when the cap is pressed downwards towards the container in this state.

[0007] In a simpler design of the two aforementioned schemes for operating the cap and thus expanding the tamper-evident ring, it is conceivable that the cover of the closure (more precisely, the mouth component) can be operated (i.e., opened) regardless of whether the cap is operated. If the cap is initially held in its initial state (supply state), the mouth component cover can be opened without first rotating the cap. Therefore, the mechanism for piercing the closure membrane can be accessed and pressed downwards toward the container to pierce the closure membrane. While this allows additives in the lower part of the closure to enter the container, the operating surface for the piercing mechanism is relatively small, thus requiring a relatively large force. To avoid this large force, in another and therefore improved scheme, the tamper-evident ring is activated when the mouth component cover is not operated; that is, it is broken by expanding the at least one predetermined fracture point through rotational or linear movement of the cap. By breaking the predetermined fracture point in this way, the cap can be moved from its first position (supply state) to another position, which simultaneously causes the mechanism for piercing the closure membrane to be activated during this movement. Because this movement involves pressing the cap downwards towards the container, the free surface of the mouthpiece cap provides a larger operating area for this movement, thus requiring less force to operate the mechanism for piercing the sealing film. After operating the mechanism for piercing the sealing film, the additive located in the lower part of the closure enters the container. Simultaneously, the piercing mechanism remains within the lower part of the closure in this pressed position, allowing the contents of the container, mixed with the additive, to be removed through the lower part of the closure along the mechanism for piercing the sealing film via the mouthpiece, preferably for drinking. The cap is also held on the lower part of the closure in a position different from the supplied state, where the predetermined break point is visually clearly identifiable and indicates that the container closure has been operated. By operating the mouthpiece cap, the mouthpiece can be resealed (as in the initial state), or it can be opened and then resealed at any time. The mouthpiece cap is also advantageously held on the cap so that this container closure unit, consisting of the lower part of the closure, the cap, and the mechanism for piercing the sealing film, can be held together and recycled together. In this case, it complies with the regulations for so-called "tethered caps". If this is not necessary, these components can also be arranged detachably from each other, thus allowing them to be separated. In this case, they can be separated for recycling.

[0008] In this development of the invention, the lower part of the closure has at least one rib generally arranged in its central region and projecting outward, wherein the at least one rib interacts with a predetermined break point of the tamper-evident ring. When the tamper-evident ring is rotated relative to the lower part of the closure by manual operation, the at least one rib expands the tamper-evident ring surrounding it. The at least one rib is located in a groove in the region of the predetermined break point of the tamper-evident ring, so that the tamper-evident ring material there, while continuous, is slightly thinner than the surrounding area. By rotation, the rib moves out of this groove and causes the tamper-evident ring to expand, resulting in the thinner area of ​​the predetermined break point breaking upon further rotation, which is visible externally. Furthermore, the cap is structurally designed so that it cannot be pressed towards the container until the at least one predetermined break point has broken.

[0009] In this development of the invention, multiple ribs are provided distributed on the outer periphery of the lower component of the closure. This firstly improves the visibility of whether the tamper-evident ring has been manipulated (i.e., whether the predetermined break point has been broken). Furthermore, this also improves the reliability of the tamper-evident ring because multiple predetermined break points must be broken before the cover can be pressed down relative to the lower component of the closure. Additionally, in this case, the force required to rotate the cover relative to the lower component of the closure is reduced because the material within the predetermined break point area can be designed to be thinner than when there is only a single predetermined break point.

[0010] In this development of the invention, the ribs are specified to be oriented parallel to the vertical axis of the container closure. Therefore, the grooves in the tamper-evident ring that form the predetermined break point are also oriented parallel to the vertical axis of the container closure. Thus, the cap, in its supplied state, reliably abuts against the lower component of its closure, and a noticeable force is required to rotate the cap in order to expand the tamper-evident ring. Therefore, for a person operating the container closure, this produces not only a visually perceptible effect but also a tactilely perceptible effect—indicating that the tamper-evident ring has been expanded, and thereby the container closure has been operated.

[0011] Furthermore, in another alternative construction design, according to the invention, the ribs are oriented off-axis from the vertical axis of the container closure. By arranging the ribs obliquely on the lower part of the closure in this way, the grooves are correspondingly oriented obliquely within the tamper-evident ring to form a predetermined break point, reducing the force required to rotate the cap relative to the lower part of the closure while maintaining the visibility of the predetermined break point after rotation. Therefore, the effect of the tamper-evident ring expanding and thus the tactilely perceptible indication that the container closure has been operated is maintained, even to a lesser extent.

[0012] As an alternative to this structural design (where the lower closure component has ribs that cause the tamper-evident ring to expand during the rotation of the cap), according to the present invention, the lower closure component has a central region that tapers towards the opening component above its fastening area. Here, in the supplied state of the container closure, the tamper-evident ring is shaped as in the aforementioned alternative and has at least one predetermined break point on its outer circumference, preferably multiple predetermined break points distributed in a dispersed manner. By pressing the cap downwards towards the container, this initially cylindrical region of the tamper-evident ring slides over the downwardly tapering central region of the lower closure component, causing the tamper-evident ring to expand and break at the predetermined break point. When the opening component is closed (the opening component cap is not operated), pressing the cap downwards in this manner activates the mechanism for piercing the sealing membrane. However, it is also possible to first open the mouthpiece cover to operate the mechanism for piercing the sealing membrane, then close the mouthpiece cover again, and then press the cover down on the tapered expansion area to expand the tamper-evident ring and tear at the predetermined break point. This provides at least one alternative structural design of how the tamper-evident ring can be expanded by pressing down.

[0013] In this development of the invention, the lower closure component is provided to have at least one support surface that at least partially, preferably completely surrounds its fastening area. This support surface interacts with the abutment surface of the cap, preferably with the lower edge surrounding the tamper-evident ring. The advantage of this interaction is primarily that, in the supplied state, the cap can withstand high loads from above without expanding the tamper-evident ring. Therefore, in the case of stacking multiple containers equipped with the container closure of the invention, for example during the storage or sale of such containers, a so-called high "top load" is ensured. Alternatively or preferably additionally, the advantage of this interaction is that, when the tamper-evident ring expands and presses the cap downward relative to the lower closure component, the support surface on the lower closure component acts as a base for the cap and thus restricts movement of the cap relative to the lower closure component. If the lower closure component has a support surface and the cap has a corresponding abutment surface, it goes without saying that the contact of these surfaces contributing to the "top load" is released as the tamper-evident ring expands, because otherwise it would be impossible to press the cap downward relative to the lower closure component. At the same time, the structure ensures that after pressing down, the abutting surface of the cover, especially the lower circumferential edge of the tamper-evident ring, abuts against the corresponding abutting surface on the lower part of the closure, thus preventing further downward pressing.

[0014] In this development of the invention, the lower closure component is specified to have at least one locking connection, wherein the cap also has at least one locking connection that interacts with the locking connection of the lower closure component. These corresponding locking connections cause the cap to be held in a correspondingly desired or necessary position relative to the lower closure component. Since these locking connections are releasable, the cap, initially held in one position, can be moved to at least one other position or exactly one other position after the at least one locking connection is released. This, for example, ensures that the cap, in the delivered state, is held in an upper position on the lower closure component, and after the cap is operated (particularly pressed down), the cap is held back in a position below the upper position. First, this has the advantage that the cap can be definitively held in its corresponding position relative to the lower closure component and cannot be moved up or down again. Furthermore, this also prevents the cap from potentially detaching from the lower closure component in the sense of "tethered caps". The corresponding locking connections can be configured, for example, as annular grooves (in the lower part of the closure) and circumferential ribs (projecting inward in the inner region of the cover), or vice versa.

[0015] In this invention, the mouth component cover is disposed on the cover via a thin-film hinge. Therefore, the mouth component cover can be easily and securely manufactured and disposed on the cover via an injection molding process. Simultaneously, the mouth component cover can be easily opened and closed.

[0016] In this development of the invention, the mouth component cover is specified to be disposed on the cap via at least one predetermined break point. Similar to the at least one predetermined break point on the tamper-evident ring, the predetermined break point between the mouth component cover and the cap also allows for visual confirmation of whether the container closure is in a supplied state (unopened) or whether it has been used (the predetermined break point between the cap and the mouth component cover has broken). It is also conceivable to replace the membrane hinge with only one or more predetermined break points. However, in this case, the mouth component cover cannot be reinstalled, and therefore resealed.

[0017] In this development of the invention, the mouthpiece cover is specified to be connected to the cover via at least one locking connection (which can be released by external force). The locking connection between the mouthpiece cover and the cover is designed such that it cannot be separated by normal manual force. Only when the hand acts on the locking connection from the outside with the aid of an additional operating element can the locking connection be separated, and then the mouthpiece cover can be separated from or lifted off the cover.

[0018] Regardless of the working principle of the container closure, the components under the closure can be constructed as a single unit or can consist of at least two parts. Attached Figure Description

[0019] The following reference Figures 1 to 7 An embodiment of the present invention will be described. Detailed Implementation

[0020] Figure 1 A container closure 10 of the present invention is shown, comprising a lower closure component 11, a cap 12 movably disposed on the lower closure component, and a mechanism 13 for piercing a sealing film (not shown). An additive is incorporated within and partially around the mechanism 13 in the lower closure component 11, wherein the lower closure component is closed in its lower region by the sealing film. The lower region of the lower closure component 11 is, for example, threaded and can be disposed or has been disposed (tightened in the case of threads) on a container (not shown) containing or potentially containing a medium. To secure the cap 12 to the lower closure component 11, the lower closure component 11 has at least one locking connection, wherein the cap 12 also has at least one locking connection that interacts with the locking connection of the lower closure component 11. When the cap 12 is pressed down relative to the lower closure component 11 toward the container, the two interacting locking connections separate or disengage (see below for details). Figure 5 ).

[0021] Figure 2 The three components of the container closure 10 are shown in detail. As can be seen in the left figure, the lower closure component 11 has a fastening region 14, through which it is positioned on the container, preferably screwed onto it. A port component 15 with an opening is provided at the opposite end region, allowing observation of... Figure 2 (Left Figure) Not visible. Between the two end regions of the lower closure component 11, the lower closure component has a central region 16. In the extension of this central region 16 (viewed from top to bottom), there is at least one surrounding step, preferably two surrounding steps 17.7 and 17.2. Ribs 18, oriented generally parallel to the vertical axis of the lower closure component 11, are also arranged in the central region 16. In this embodiment, there are multiple ribs 18 distributed on the outer periphery.

[0022] exist Figure 2 The middle figure shows a mechanism 13 for piercing the closure membrane. The upper end of the mechanism 13 can be pressed, while the lower end of the mechanism 13 is pressed down (observation). Figure 2 (From top to bottom) Pierce and thus open the sealing membrane (not shown), so that the additives present in the lower part 11 of the sealing member can enter the container located below.

[0023] exist Figure 2The right figure shows cover 12, which can be used as a cover. Figure 1 As seen in the diagram, it is positioned above the upper portion of the lower closure component 11 in the supplied state. The cover 12 also has a central region 19, above which a movable opening component cover 20 is arranged, and below which an tamper-evident ring 21 is arranged. These components integrally—but can also be movable if necessary (the opening component cover 20)—form the cover 12. At least one predetermined break point 22 is provided in the tamper-evident ring 21. In practice, multiple predetermined break points 22 are distributed on the outer periphery of the tamper-evident ring 21. (The last sentence appears to be incomplete and possibly refers to a different design.) Figure 1 As can be seen, at least one predetermined break point 22 has not yet broken in the supplied state. The mouth part cover 20 (preferably connected to the central region 1 via a membrane hinge 23) is provided. To prove that the mouth part cover 20 has not been operated in the supplied state, a predetermined break point 24 is provided. If the mouth part cover 20 has been operated (i.e. opened) via the membrane hinge 23 to approach the mouth part 15 of the lower part of the closure 11, the predetermined break point 24 will break.

[0024] Figure 3 The diagram illustrates how the cover 12 needs to be moved from its supplied state to expand the tamper-evident ring 20. The tamper-evident ring 21 expands by rotating the cover 12 relative to the lower closure member 11 via a rotational movement D. The rotational movement D can be limited by corresponding stop stops between the lower closure member 11 and the cover 12, but is not mandatory. After this rotational movement D, reference can be made to… Figure 3 Press the lid 12 downwards towards the container (not shown) by applying force from top to bottom.

[0025] Figure 4 The function of the tamper-proof ring 21 is shown in detail. (Observation) Figure 4 As can be seen from the left and middle enlarged views, grooves are provided around the tamper-evident ring 21. In the supplied state, when the cover 12 is placed on the lower closure component 11, the ribs 18 of the lower closure component 11 are fitted into these grooves. In this state, the predetermined break point 22 has not yet opened. If a rotational movement D occurs, i.e., the cover 12 rotates around the lower closure component 11 by an external force, the ribs 18 are transferred from the thinner area of ​​the tamper-evident ring 21 to the thicker area, causing the tamper-evident ring 21 to expand S. Due to the thinness of the material of the tamper-evident ring 21, this expansion causes the predetermined break point 22 to break. This means that the tamper-evident ring 21 breaks and expands because the ribs 18 are preferably designed in a conical shape. The connection between the upper part of the tamper-evident ring 21 and the middle region 19 of the cover 12 acts as a hinge, which allows for... Figure 4As can be clearly seen in the right-hand image.

[0026] After rotating the cover 12 relative to the lower part 11 of the closure and expanding the tamper-evident ring 21, the cover 12 can be pressed downward by moving K. Figure 5 This is illustrated in the text.

[0027] Regarding the sequence and process of the lid 12 moving towards the container, the following aspects should also be noted. In such cases... Figure 1 In the supplied state shown, the lower edge of the tamper-evident ring 21 is positioned on the surrounding step 17.2 of the lower closure component 11. This means that the cover 12 is supported on the lower closure component 11 in the supplied state, and the cover 12 is prevented from shifting downwards in this state. Therefore, the necessary "top load" is achieved. When the cover 12 is rotated and the tamper-evident ring 21 expands (see...), Figure 3 This releases the lower edge of the tamper-evident ring 21 from its contact with the surrounding step 17.2. Only by releasing this contact can the cover 12 be pressed downwards. To definitively stop the cover 12 from moving downwards, the additional surrounding step 17.1 is located in the transition area between the fastening area 14 and the middle area 16 of the lower part of the closure 11. If according to... Figure 5 Press the cover 12 in direction H, and the lower edge of the tamper-evident ring 21 will finally abut against the surrounding step 17.1, thus preventing further downward pressure.

[0028] As an alternative, the cover has ribs that rest against step 17.2 after the expansion and downward pressing, thus similarly stopping the movement.

[0029] The end of the movement of the cap 12 activates the container closure 10 because the closure membrane is opened by pressing down on the mechanism 13, which also serves to pierce the closure membrane and moves axially downward. Thus, the additive in the lower part 11 of the closure enters the container (not shown) located below it.

[0030] After the container closure 10 is activated, the additive can be mixed with the medium in the container and removed. For example... Figure 6 The design of the container closure 10 shown makes this removal possible. A tamper-evident ring 21 is held in the position shown, allowing the opening cover 20, located on the central region 19 of the cap 12, to be operated (i.e., opened). Here, the opening cover 20 is broken at a predetermined breaking point 24 by applying force from the outside (e.g., by hand), and can be pivoted via a membrane hinge 23, thereby allowing access to the opening 15 of the lower part 11 of the closure. Since the upper portion of the opening 15 is open after pressing down the mechanism 13, the medium, such as for drinking, can be removed from the container.

[0031] Figure 7 The illustration shows a scenario where the medium inside the container has not been completely emptied, in which case the port cover 20 is folded back via the membrane hinge 23, thereby closing the opening in the port component 15. The cover 12 and the remaining components of the mechanism 13 no longer move. To ensure this, the lower closure component 11 has at least one locking connection, and the cover 12 also has at least one locking connection that interacts with the locking connection of the lower closure component 11. By pressing downwards in direction H, these two locking connections engage with each other, thereby securing the cover 12 to the lower closure component 11 in the downward-pressed state.

[0032] pass Figures 1 to 7 The illustrated design of the container closure 10 and its corresponding operating principle allow (but are not required to) design the tamper-evident ring 21 in such a way that the sealing membrane can only be punctured by the mechanism 13 when the tamper-evident ring 21 is operated. This is because, in principle, the opening member cap 20 can also be opened, exposing the upper end of the mechanism 13, and then the cap 12 can be rotated around the lower closure member 11, or not rotated at all, to expand the tamper-evident ring 21. During this expansion, the mechanism 13 is still not operated; this operation is only achieved simultaneously with, or may even be separated from, the downward pressing of the cap 12 toward the container. The latter is possible because, with the opening member cap 20 open, the cap 12 does not automatically actuate the mechanism 13 when pressed downwards.

[0033] The film can also be pierced after lifting the mouth part cover 20 by, for example, pressing the exposed and thus protruding upper area of ​​the mechanism 13 with a finger, without rotating the moving cover 12 and activating the tamper-evident ring 21. Figure 8 In the diagram, corresponding to Figures 1 to 7 The structural design shown illustrates the sequence of actions for operating the alternative container closure. Figure 8 In the design of the container closure, besides having the same components and their same actions, the lower closure component 11 has a central region 16 that tapers towards the opening component 15 above its fastening region 14. In this embodiment, by referring to... Figure 8 Press the cap 12 downwards (i.e., towards the container where the container closure is located) to expand the tamper-evident ring 21. The tamper-evident ring 21 breaks at its predetermined break point 22 by tapering downwards through the central region 16. Before the cap 12 can be pressed downwards, according to... Figure 8The two lower left diagrams show that the cap 12 needs to be rotated from a first position (supply state) to another position, for example, by approximately or exactly 90 degrees. This helps protect the container closure from accidental pressing (and thus operation of mechanism 13) and serves as an externally identifiable indication that the container closure has not been operated (and is therefore new and unused). This rotation process is preferably performed before downward pressing, although alternatively the rotation process can be omitted, allowing the cap 12 to be pressed down directly to expand the tamper-evident ring 21 and operate mechanism 13 without prior rotation.

[0034] exist Figures 9 to 11 The diagram shows that the mouth part cover 20 is connected to the cover 12 via at least one latching connection that can be released by an externally applied force, particularly to the central region 19 of the cover 12.

[0035] This design is an alternative to having the mouth component cover 20 arranged on the cover 12, wherein there is a locking connection that replaces the predetermined break point 24, which can only be released by external force, thereby releasing the locking connection to open the mouth component cover 20, i.e., by pivoting around the membrane hinge 23 or by other opening methods.

[0036] In the initial state, especially in the supply state, the mouth component cover 20 is in Figure 9 The first position shown is located on the upper region of the cover 12. The mouthpiece cover 20 is secured by a membrane hinge 23. However, the mouthpiece cover 20 can only be operated by pivoting around the membrane hinge 23 when the locking connection formed by the latch 25 on the mouthpiece cover 20 and another corresponding latch 26 on the cover 12 is released by applying an external force. To allow the external force to release the locking connection, a protrusion 27 (e.g., configured as a flange) is arranged as an additional operating element on the lower closure member 11, and a corresponding ramp 28 is arranged on the cover 12. The protrusion 27 and the ramp 28, which can be operably connected thereto, are arranged either completely or partially around the lower closure member 11 or the cover 12. They can also be multiple times around the lower closure member 11, broken by non-corresponding and operably connected areas.

[0037] Figure 9 As shown, the two locking hooks 25, 26 interact and connect, thus preventing operation of the mouth part cover 20, and in particular preventing it from pivoting around the membrane hinge 21 to access the mouth part 15.

[0038] Figure 10This state is shown again in the form of a detailed cross-sectional view. It can be seen that the cover 12 has a thicker wall region below its locking hook 28, which gradually thins along the slope 28 until the cover 12 has a smaller material thickness at the height of the protrusion 27. Figure 10 The inclined plane 28 shown is stepped. As an alternative, it can also extend in an arc shape.

[0039] When the cover 12 is pressed as an external force, or more precisely, when the surface of the cover 20 of the pressing port component is pressed, the cover 12 moves downward, see reference. Figure 9 and 10 By pressing downwards toward the container (not shown), the slope 28 reaches the protrusion 27, that is, the thinner-walled area of ​​the cover 12 first slides on the protrusion 27 of the lower closure member 11 and reaches the thicker-walled area of ​​the cover 12, thereby expanding the area of ​​the cover 12 in the region of the locking connections 25, 26. This expansion causes the upper portion of the cover 12 in the region with the locking hook 26 to separate (lift) from the locking hook 25 of the mouth member cover 20, as... Figure 11 As shown. In this state, the locking connections 25 and 26 are released, so the port component cover 20 can be moved, thereby allowing access to the port component of the lower closure component 11.

[0040] exist Figures 9 to 11 In the illustrated embodiment, the locking connections 25, 26 exist only on a small portion of the outer periphery of the cover 12 or the mouth component cover 20, and are preferably opposite to the membrane hinge 23. However, as an alternative, it is also possible to provide multiple locking connections on the partial outer periphery, rather than just one. In this case, the membrane hinge 23 can be completely omitted, especially if the locking connections 25, 26 are provided on the entire outer periphery of the cover 12 and correspondingly on the mouth component cover 20, or on multiple partial outer peripheries (disconnected by partial outer peripheries without locking connections).
