Description

Technology Field

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

[0002] DE 10 2014 207 652 A1 discloses a container closure (1) comprising a closure bottom part (5) and a cap (2), and also a mouthpiece (3) and means for piercing a closure film, wherein the container closure (1) is provided with a tamper-evident band (6), said tamper-evident band (6) ensures that the closure film can be pierced by said piercing means only when the tamper-evident band (6) is removed, said tamper-evident band (6) is positioned between the closure bottom part (5) and the cap (2). Reference numerals follow those described in said document.

[0003] Additionally, DE 10 2017 100 184 A1 discloses a container closure (1) comprising a closure bottom (5) and a cap (2), and also having a mouthpiece (3) and means for perforating a closure film, wherein the container closure (1) is provided with an opening prevention band (6), wherein the opening prevention band (6) ensures that the closure film can be perforated by the perforating means only when the opening prevention band (6) is removed, wherein the opening prevention band (6) is positioned between the closure bottom (5) and the cap (2), wherein the opening prevention band (6) is formed in the shape of a closure ring and is connected to the lower edge of the cap (2) via at least one separable web (8), and wherein the cap (2) is mounted on the closure bottom (5) so as to be partially rotatable and pressurizable. Reference numerals follow those described in the aforementioned document. The problem to be solved

[0004] The object of the invention is to improve the handling and environmental compatibility of a known container closure having a tamper-evident band (sealing ring). means of solving the problem

[0005] The above objective is achieved by configuring the anti-opening band to have a plurality of predetermined breaking points oriented along the axial direction of the container closure and to be activated by a spreading procedure. Before the predetermined breaking points are separated, it is easy to visually confirm that the anti-opening band has not yet been activated, that is, that the container closure is still in an intact state. When activated, the predetermined breaking points distributed along the circumference of the container closure are separated by a simple pressurizing action, making the handling of the container closure easy. After pressurization, the anti-opening band is seated on the container closure in an interference fit manner and remains in place, thereby allowing all parts of the container closure to be disposed of together without the separation or loss of individual parts of the container closure causing environmental pollution, and in particular, to be recyclable.

[0006] The spreading procedure (of the tamper-proof band) can be performed in various ways. On the one hand, it is possible to configure the system so that the tamper-proof band spreads as the cap is released from its initial state and rotated. After this operation is completed, it is possible to press the cap downward toward a container, particularly a screw-coupled container, to which the container closure is attached, thereby activating a means for perforating the sealing film. Accordingly, an additive placed at the bottom of the closure can be released and moved toward the container. On the other hand, it is also possible to first release and rotate the cap from its initial state while the tamper-proof band is not spread. In this case, the spreading of the tamper-proof band occurs only when the cap is pressed downward toward the container in this state.

[0007] As a simpler form of the two variations of the above-described activation of the cap and the resulting spreading of the tamper-evident band, it is also possible to allow the cover of the closure (more precisely, the mouthpiece cover) to operate, i.e., open independently of this. If the cap remains in its initial state (delivery state), it is possible to consider opening the mouthpiece cover without rotating the cap. In this way, a means for perforating the closure film becomes accessible, and the closure film can be perforated by pressing the perforating means downward toward the container. This allows the additive located at the bottom of the closure to flow into the container, but a greater force must be applied because the surface area (contact area) for operating the perforating means is relatively small. To avoid the need for such large force, in another, and thus improved, variant, the tamper-proof band is configured to be activated while the mouthpiece cover is not engaged, that is, at least one predetermined break is broken as the tamper-proof band unfolds due to rotational movement or linear movement of the cap. By breaking the predetermined break, the cap can be moved from a first position (shipping state) to an additional position, and this movement has the effect of causing the means for perforating the closure film to move simultaneously with this movement. Since this movement involves a downward pressing action of the cap toward the container, the free surface of the mouthpiece cover provides a larger working surface area for this movement, thereby reducing the force required to activate the means for perforating the closure film. After the means for perforating the closure film is activated, an additive located at the bottom of the closure is introduced into the container.Simultaneously, the perforation means remains in a downwardly pressurized position within the bottom of the closure, thereby allowing the container contents mixed with the additive to be discharged through the mouthpiece via the bottom of the closure along the perforation means of the closure film, and preferably to be consumed. The cap is also maintained in the bottom of the closure at a position different from the shipping state, where a specific fractured section is very clearly visible, serving as an indication that the container closure has already been activated. By operating the mouthpiece cover, it is possible to close the mouthpiece again (as was possible in the initial state), or to open and close it again at any time as needed. The mouthpiece cover is also advantageously maintained in a continuous connection to the cap, so that the container closure unit, consisting of the bottom of the closure, the cap, and the means for perforating the closure film, is maintained together and can be recycled as a whole. In this case, the requirements for a so-called “tethered cap” are satisfied. If such requirements are not required, the components may be arranged so that they can be separated from each other, thereby making it possible to separate the components from each other. In this case, it is also possible to separate the above components and recycle them individually.

[0008] According to one advanced embodiment of the present invention, the bottom of the closure comprises at least one web that is approximately positioned in its central region and faces outward, and is configured to interact with a predetermined break portion of the tamper-proof band. The at least one web causes the circumferential tamper-proof band to expand (spread out) when the tamper-proof band is rotated by hand relative to the bottom of the closure. The at least one web is located within a recess formed in the tamper-proof band in the predetermined break portion region, thereby maintaining the material of the tamper-proof band continuously at that location but forming it somewhat thinner than the surrounding region. Upon rotation, the web is disengaged from the recess to spread (widen) the tamper-proof band, and as a result, the thin region of the predetermined break portion is broken by further rotation, which can be visually confirmed from the outside. Additionally, the cap is designed so that it cannot be pressed downward toward the container until at least one predetermined break portion is broken.

[0009] According to another advanced form of the present invention, a plurality of webs distributed along the circumference of the bottom portion of the closure are provided. Accordingly, it is possible to more clearly confirm whether the anti-opening band has been activated, that is, whether a predetermined break portion has been broken. In addition, in this configuration, the safety of the anti-opening band is improved because a plurality of predetermined break portions must be broken before the cap is pressed downward against the bottom portion of the closure (i.e., the cap can be pressed downward against the bottom portion of the closure only after a plurality of predetermined break portions have been broken). Furthermore, in this case, the force required to rotate the cap against the bottom portion of the closure is reduced because the material in the area of ​​the predetermined break portion can be formed thinner than in the case where only a single predetermined break portion exists.

[0010] According to another advanced form of the present invention, the web is configured to be oriented parallel to the vertical axis of the container closure. Accordingly, the recess of the anti-opening band for forming a predetermined break is also oriented parallel to the vertical axis of the container closure. As a result, the cap is stably seated on the bottom of the closure in the shipping state, and a clearly perceptible force is required when the cap is twisted and rotated to unfold the anti-opening band. Accordingly, the user activating the container closure is provided with an effect that allows not only visual recognition that the anti-opening band has unfolded and the container closure has been activated, but also tactile recognition.

[0011] According to an alternative embodiment of the present invention, the web may be oriented to be deflected with respect to the vertical axis of the container closure. By positioning the web at a predetermined angle on the bottom portion of the closure and oriented the recess of the anti-opening band to have a predetermined angle to form a predetermined break portion in correspondence, the force required to twist and rotate the cap against the bottom portion of the closure is reduced, while at the same time, the visibility of the predetermined break portion is maintained even after such twisting. Accordingly, the tactilely perceptible effect indicating that the anti-opening band has unfolded and the container closure has been activated is maintained, although somewhat weakened.

[0012] As an alternative to the configuration of forming a web on the bottom of the closure to cause the tamper-proof band to unfold upon rotation of the cap, according to the present invention, the bottom of the closure may be configured to have a central region that tapers conically toward the mouthpiece on the upper part of the fastening area. In this case, the tamper-proof band in the shipping state of the container closure has a cylindrical shape, similar to the alternative described above, and has at least one predetermined break portion along its circumference, preferably a plurality of predetermined break portions distributed along the circumference. When the cap is pressed downward in the direction of the container, the tamper-evident band, which initially maintains a cylindrical shape, slides along the downwardly conically widening central region of the closure bottom part, causing the tamper-evident band to spread and the predetermined breaking points to break open. When the cap is pressed down while the mouthpiece is closed (i.e., the mouthpiece cover is not operated), the means for perforating the closure film moves together. However, it is also possible to first open the mouthpiece cover to operate the means for perforating the closure film, then close the mouthpiece cover again, and then press the cap downward along the conically widening region to spread the tamper-evident band and break the predetermined breaking points.Accordingly, this provides at least one additional structural embodiment capable of unfolding the opening prevention band by downward pressure.

[0013] According to another advanced form of the present invention, the bottom portion of the closure is provided with at least one, at least partially, preferably completely, circumferentially formed support surface above its fastening area, said support surface is configured to interact with the contact surface of the cap, preferably the circumferential lower edge of the anti-opening band. This interaction provides the advantage that a large load can be applied to the cap from above even when the anti-opening band is not unfolded in the shipping state. Accordingly, a high “top load” can be secured even when a plurality of containers equipped with the container closure according to the present invention are typically stacked together, for example, during storage or sale of such containers. Alternatively, or preferably in addition thereto, said interaction provides the effect of restricting the movement of the cap relative to the bottom portion of the closure by the support surface of the bottom portion of the closure contacting the cap after the anti-opening band is unfolded and the cap is pressed downward against the bottom portion of the closure. When a support surface is formed on the bottom of the closure and a corresponding contact surface is formed on the cap, it is evident that when the anti-opening band is unfolded, the contact between these surfaces that generate the “upper load” is released, because otherwise, it would be impossible to press the cap downward against the bottom of the closure. At the same time, according to the present design, after downward pressing, the contact surface of the cap, in particular the circumferential lower edge of the anti-opening band, is configured to rest on the corresponding contact surface of the bottom of the closure, and accordingly, additional downward pressing is no longer possible.

[0014] According to another advanced form of the present invention, the closure bottom is provided with at least one latching connection, and the cap is also provided with at least one latching connection that interacts with the latching connection of the closure bottom. By means of these corresponding latching connections, the cap is ensured to be maintained in each desired or required position relative to the closure bottom. Since the latching connection is formed to be releaseable, after at least one latching connection is released, the cap, which was initially maintained in one position, can be moved to at least one additional position or exactly one different position. Accordingly, for example, the cap may be maintained in an upper position on the closure bottom in the shipping state, and after the cap is activated (particularly after being pressed downward), it may be maintained again in a position lower than the upper position. This provides the advantage that the cap is maintained in a defined manner relative to the closure bottom at each position so that it cannot be moved further in the vertical direction. Furthermore, this configuration also prevents the cap from being separated or detached from the closure bottom in the sense of a so-called “tethered cap.” The corresponding latching joints may be formed, for example, by a circumferential groove (formed in the bottom portion of the closure) and a circumferential web (directed inward in the inner region of the cap), or by the opposite configuration or a similar configuration.

[0015] According to another advanced form of the present invention, a mouthpiece cover is provided to be placed on a cap via a film hinge. Accordingly, the mouthpiece cover can be easily manufactured using an injection molding process and placed on the cap so as not to detach. At the same time, the mouthpiece cover can be easily opened and can be closed again after opening.

[0016] According to another advanced form of the present invention, a mouthpiece cover is provided to be disposed on a cap through at least one predetermined opening. Similar to at least one predetermined opening formed in an tamper-proof band, a predetermined opening between the mouthpiece cover and the cap can also be used to visually determine whether the container closure is in a shipping state (unopened state) or has already been used (a state in which the predetermined opening between the cap and the mouthpiece cover is broken). Additionally, a configuration is possible that provides only one predetermined opening or multiple predetermined openings instead of a film hinge. However, in this case, since the mouthpiece cover cannot be reattached, it is impossible to reseal the container.

[0017] According to another advanced form of the present invention, a mouthpiece cover is provided to be connected to a cap through at least one latching connection that can be released by an external force. The latching connection between the mouthpiece cover and the cap is designed so that it cannot be released by ordinary hand force. The latching connection can be released only when force is applied to the latching connection by hand with the assistance of an additional operating element from the outside, after which the mouthpiece cover can be separated from or opened from the cap.

[0018] Regardless of the operating mode of the container closure, the bottom portion of the closure may be formed as a single unit or may consist of at least two parts. Effects of the invention

[0019] The present invention has the effect of improving the handling and environmental suitability of a known container closure equipped with an opening prevention band (seal ring). Brief explanation of the drawing

[0020] Hereinafter, an embodiment according to the present invention will be described with reference to FIGS. 1 to 7. FIG. 1 illustrates a container closure (10) according to the present invention. FIG. 2 illustrates in detail the three elements constituting the container closure (10). FIG. 3 illustrates how the cap (12) must be moved from the shipping state so that the opening prevention band (21) is unfolded by the movement. Figure 4 illustrates the function of the tamper-proof band (21) in detail. Figure 5 illustrates the operation (activation) of the system. Figure 6 illustrates the opening of the mouthpiece cover and the state of preparation for drinking. Figure 7 illustrates the case where the medium inside the container has not yet been completely emptied. The drawings in FIG. 8 illustrate a sequence of operations for activating an alternative container closure according to the embodiments shown in FIG. 1 to 7. FIGS. 9 to 11 illustrate that the mouthpiece cover (20) is connected to the cap (12), particularly the central region (19) of the cap (12), through at least one latching joint that can be released by an external force. Specific details for implementing the invention

[0021] FIG. 1 illustrates a container closure (10) according to the present invention, wherein the container closure (10) comprises a closure bottom portion (11), a cap (12) movably disposed on the upper portion of the closure bottom portion (11), and means (13) for perforating a closure film (not shown). An additive is filled within the closure bottom portion (11), including the interior of the means for perforating (13) and a portion of the area around it, and the lower portion of the closure bottom portion is closed by a closure film. A screw thread is formed, for example, in the lower portion of the closure bottom portion (11), and may be placed in or disposed of in a container (not shown) in which a medium is filled or can be filled, and if the screw thread is formed, it is fastened to the container by a screw connection. In order to secure the cap (12) to the closure bottom (11) in a defined manner, the closure bottom (11) has at least one latching connection, and the cap (12) also has at least one latching connection that interacts with the latching connection of the closure bottom (11). These two interacting latching connections are released or separated from each other when the cap (12) is pressed downward toward the container against the closure bottom (11) (see FIG. 5 described later).

[0022] FIG. 2 illustrates in detail the three elements constituting the container closure (10). As can be seen from the drawing on the left, the bottom portion of the closure (11) has a fastening region (14) that allows the bottom portion of the closure (11) to be placed in the container, and is preferably fastened to the container by a screw connection. A mouthpiece (15) is formed in the other end portion on the opposite side, and, with respect to the drawing on the left of FIG. 2, no externally identifiable opening is formed in the mouthpiece. A central region (16) is formed between the two end portions of the bottom portion of the closure (11). At least one circumferential shoulder is formed along the central region (16) (when viewed from top to bottom), and preferably two circumferential shoulders (17.1, 17.2) are formed. Additionally, a web (18) is formed in the central region (16) and oriented approximately parallel to the vertical axis of the closure bottom portion (11). In this embodiment, a plurality of webs (18) are distributed along the circumference.

[0023] The central drawing of FIG. 2 illustrates a means (13) for perforating a closing film. The upper portion of the means (13) is formed to be pressurizable. When the perforating means (13) is pressed from the top to the bottom direction with reference to FIG. 2, the lower portion of the perforating means (13) penetrates and breaks the closing film (not shown), thereby opening the closing film and allowing the additive present in the bottom portion (11) of the closure to flow into the container below.

[0024] The right side of FIG. 2 illustrates a cap (12), which, as can be seen in FIG. 1, is positioned on the upper part of the closure bottom portion (11) in the shipping state. The cap (12) also has a central area (19), a movable mouthpiece cover (20) is positioned on the upper part thereof, and a tamper-evident band (21) is positioned on the lower part thereof. These components form the cap (12) integrally, while the mouthpiece cover (20) can be formed to be movable. At least one predetermined breaking point (22) is formed in the tamper-evident band (21), and in practice, a plurality of predetermined breaking points (22) are provided distributed along the circumference of the tamper-evident band (21). Also, as can be seen in FIG. 1, in the shipping state, at least one predetermined breaking point (22) is maintained in a state where it has not yet broken. The mouthpiece cover (20) is connected to the central region (19), preferably via a film hinge (23). A predetermined break (24) is provided to indicate that the mouthpiece cover (20) is not yet operated in the shipping state. The predetermined break (24) breaks when the mouthpiece cover (20) is operated via the film hinge (23), that is, when it is opened to make the mouthpiece (15) of the closure bottom (11) accessible.

[0025] FIG. 3 illustrates how the cap (12) must be moved from its shipping state so that the tamper-proof band (21) spreads out by that movement. When the cap (12) is rotated (D) relative to the closure bottom (11), the tamper-proof band (21) slides over the web (18) of the closure bottom (11), and the tamper-proof band (21) spreads out. The rotational movement (D) may be limited by a corresponding stopper formed between the closure bottom (11) and the cap (12), but such limitation is not necessarily required. After the rotational movement (D) is performed, as shown in FIG. 3, it is possible to press the cap (12) downward toward the container (not shown) by applying force from the top to the bottom.

[0026] FIG. 4 illustrates in detail the function of the tamper-proof band (21). Looking at the left drawing and the central enlarged drawing of FIG. 4, recesses are formed along the entire circumference of the tamper-proof band (21), and it can be seen that when the cap (12) is placed on the closure bottom part (11) in the shipping state, the web (18) of the closure bottom part (11) is seated within the recesses. In this state, a predetermined break portion (22) is not yet open. When rotational movement (D) occurs around the closure bottom part (11), that is, rotational movement caused by an external force acting on the cap (12), the web (18) moves from a thinner area of ​​the tamper-proof band (21) to a thicker area of ​​the tamper-proof band (21), and as a result, spreading occurs in the tamper-proof band (21). Since the material thickness of the opening prevention band (21) is relatively thin in that area, a predetermined break portion (22) is broken by this unfolding. This means that the opening prevention band (21) is broken and unfolded simultaneously because the web (18) is preferably formed in a conical shape. In addition, the part where the upper portion of the opening prevention band (21) is connected to the central area (19) of the cap (12) acts as a hinge, which can be clearly seen in the right-hand drawing of FIG. 4.

[0027] After the cap (12) is rotated relative to the bottom portion (11) of the closure and the opening prevention band (21) is unfolded, the cap (12) can be pressed downward by a movement (K) as shown in FIG. 5.

[0028] In this regard, regarding the arrangement and sequence of operations in which the cap (12) moves toward the container, the following additional points need to be noted. In the shipping state illustrated in FIG. 1, the circumferential lower edge of the anti-opening band (21) rests on the circumferential shoulder (17.2) of the bottom portion of the closure (11). This means that in the shipping state, the cap (12) is supported by the bottom portion of the closure (11), and thus, the cap (12) is prevented from moving downward. This ensures the required “top load.” The state in which the lower edge of the anti-opening band (21) contacts the circumferential shoulder (17.2) is released when the cap (12) is rotated and the anti-opening band (21) is unfolded (see FIG. 3). Only when this contact is released can the cap (12) be pressed downward. In order to stop the downward movement of the cap (12) in a defined manner, an additional circumferential shoulder (17.1) is formed in the transition portion between the fastening area (14) and the central area (16) of the bottom portion (11) of the closure. As shown in FIG. 5, when the cap (12) is pressed downward in the direction H, the circumferential lower edge of the anti-opening band (21) finally rests on the circumferential shoulder (17.1), and accordingly, further downward pressing of the cap (12) is no longer possible.

[0029] Alternatively, the cap may be provided with a web that rests on the shoulder (17.2) after unfolding and downward pressure, thereby stopping the movement of the cap as well.

[0030] The cap may be configured to have a web so that after the opening prevention band is unfolded and the cap is pressed downward, the web is seated on the cylindrical shoulder (17.2), and in this case, the movement of the cap is also stopped.

[0031] When the movement of the cap (12) is completed in this manner, the container closure (10) is activated, because the means (13) for perforating the closure film moves downward in the axial direction due to the downward pressure, and as a result, the closure film is opened. Accordingly, the additive contained within the bottom part (11) of the closure flows into the container (not shown) located below it.

[0032] After the activation of the container closure (10) is achieved, the additive can be mixed with the medium inside the container and subsequently discharged. This discharge is made possible by the configuration of the container closure (10) as illustrated in FIG. 6. The opening prevention band (21) remains in the illustrated position, and the mouthpiece cover (20) placed in the central area (19) of the cap (12) can be operated, that is, opened. A predetermined break portion (24) is broken by an external force, for example, a force applied by a hand, and accordingly, the mouthpiece cover (20) can be rotated through the film hinge (23), and as a result, the mouthpiece (15) of the bottom portion (11) of the closure becomes accessible. After the perforation means (13) is pressed downward, the upper end area of ​​the mouthpiece (15) becomes open, so the medium can be discharged from the container and, for example, consumed.

[0033] FIG. 7 illustrates a case where the medium inside the container has not yet been completely emptied, in which case the mouthpiece cover (20) is folded back through the film hinge (23) to close the opening of the mouthpiece (15). In this state, other parts of the cap (12) and the perforation means (13) do not move further. To ensure this, the closure bottom (11) is provided with at least one latching joint, and the cap (12) is also provided with at least one latching joint that interacts with the latching joint of the closure bottom (11). By applying downward pressure in the direction H, these two latching joints are joined together, and thus the cap (12) is fixed to the closure bottom (11) while under downward pressure.

[0034] However, in the design of the container closure (10) and the corresponding mode of operation shown in FIGS. 1 to 7, the opening prevention band (21) does not necessarily need to be provided in a manner that ensures the closing film is perforated by the perforation means (13) only when the opening prevention band (21) is activated. This is because, in principle, it is possible to open the mouthpiece cover (20) to freely expose the upper part of the perforation means (13), and then, if necessary, rotate the cap (12) around the bottom part (11) of the closure to unfold the opening prevention band (21). During this unfolding process, the perforation means (13) is not yet activated, and this (activation) occurs when the cap (12) is pressed downward toward the container or independently thereof. This is because, when the mouthpiece cover (20) is open, the perforation means (13) is not automatically moved together with the cap (12) even if the cap (12) is pressed downward.

[0035] After the mouthpiece cover (20) is folded open, it is possible to puncture the closing film without activating the opening prevention band (21) by twisting the cap (12) by pressing the freely exposed and protruding upper area of ​​the puncturing means (13), for example, using a finger. The illustrations in FIG. 8 illustrate a sequence of operations for activating an alternative container closure corresponding to the embodiments illustrated in FIG. 1 through 7. In addition to similar components and similar operations therewith, in the configuration of the container closure illustrated in FIG. 8, the bottom portion of the closure (11) has a central area (16) that gradually narrows conically toward the mouthpiece (15) above its fastening area (14). In this embodiment, as seen in FIG. 8, the opening prevention band (21) is unfolded by pressing the cap (12) downward, that is, toward the container to which the container closure is mounted. As the central region (16) expands conically in a downward direction, a predetermined break portion (22) of the tamper-evident band (21) is broken. Before pressing the cap (12) downward, as shown in the two drawings in the lower left of FIG. 8, the cap (12) must first be rotated from a first position (shipping state) to another position, for example, about 90 degrees or exactly 90 degrees, so that the cap (12) can be pressed downward. This is to prevent accidental downward pressing of the cap (12) in the container closure (and the subsequent activation of the perforation means (13)), and functions as a clear external indicator to identify the container closure that is not activated (and thus is new and unused). This rotational motion is preferably performed before downward pressure, but alternatively, it is also possible to omit the rotational motion and directly apply downward pressure to the cap (12) without prior rotational motion to unfold the opening prevention band (21) and activate the perforation means (13).

[0036] FIGS. 9 to 11 illustrate that the mouthpiece cover (20) is connected to the cap (12), particularly the central region (19) of the cap (12), through at least one latching connection that can be released by an external force.

[0037] This embodiment is an alternative form of configuration for placing a mouthpiece cover (20) on a cap (12); here, instead of a predetermined break portion (24), a latching coupling that can be released only when a force is applied from the outside is provided, so that the mouthpiece cover (20) can be opened by releasing the latching coupling, that is, the mouthpiece cover (20) can be opened by rotational movement around the film hinge (23) or by other methods of opening.

[0038] In the initial state, particularly in the shipping state, the mouthpiece cover (20) is positioned in a first position on the upper region of the cap (12) as shown in FIG. 9. Meanwhile, the mouthpiece cover (20) is secured via a film hinge (23). However, operation by rotation of the mouthpiece cover (20) around the film hinge (23) is possible only when the latching joint formed by the latching hook (25) formed on the mouthpiece cover (20) and the corresponding additional latching hook (26) formed on the cap (12) is released by the application of external force. In order for the latching joint to be released by external force, a projection (27) formed in the shape of a bead is placed on the bottom of the closure (11) as an additional operating element, and a corresponding bevel (28) is formed on the cap (12). The above-mentioned protrusion (27) and the inclined surface (28) that can be operatively coupled thereto may be arranged along the entire or partial perimeter of the closure bottom (11) and the cap (12), respectively. Additionally, multiple such protrusions may be arranged along the perimeter in a manner that they do not correspond to one another or are separated by operatively coupled regions.

[0039] FIG. 9 illustrates a state in which two latching hooks (25, 26) are operatively coupled to each other, thereby making it impossible to operate the mouthpiece cover (20), particularly to rotate the mouthpiece cover (20) around the film hinge (23) to open it and make the mouthpiece (15) accessible.

[0040] FIG. 10 illustrates this state again in an enlarged detail. As can be seen here, the cap (12) has a relatively thick wall thickness region at the bottom of the latching hook (26), and said wall thickness region tapers along the inclined surface (28) and transitions to a thinner material thickness of the cap (12) at a position corresponding to the height of the protrusion (27). In FIG. 10, the inclined surface (28) is shown in a stepped shape. Alternatively, it may be formed in a curved shape.

[0041] When external force is applied to the surface of the cap (12), more precisely the mouthpiece cover (20), the cap (12) moves downward, as shown in FIGS. 9 and 10. Due to this downward pressure in the direction of the container (not shown), the inclined surface (28) comes into contact with the protrusion (27), that is, the area of ​​the cap (12) having a thinner wall thickness initially slides along the protrusion (27) of the bottom part of the closure (11) and subsequently reaches the area of ​​the cap (12) having a thicker wall thickness, and as a result, the corresponding part of the cap (12) expands (widens) in the area where the latching joint (25, 26) is formed. This widening has the effect of separating (lifting) the upper area of ​​the cap (12) where the latching hook (26) is formed from the latching hook (25) of the mouthpiece cover (20), as shown in FIG. 11. In this state, the latching joint (25, 26) is released, making it possible to move the mouthpiece cover (20), and thereby making the mouthpiece of the closure bottom part (11) accessible.

[0042] In the embodiment illustrated in FIGS. 9 to 11, the latching joint (25, 26) is formed only in a limited section of the circumference of the cap (12) or the mouthpiece cover (20), preferably on the opposite side of the film hinge (23). However, alternatively, it is possible to provide multiple partial circumferential latching joints between the cap (12) and the mouthpiece cover (20), rather than being limited to a single partial circumferential latching joint. In this case, particularly when the latching joint (25, 26) is formed over the entire circumference of the cap (12) and the corresponding mouthpiece cover (20), or when it is formed over multiple partial circumferences (separated by the circumference of the part where the latching joint is not formed), it is possible to completely omit the film hinge (23).
