Abstract
Description
Technical Field
[0001] The present invention relates to a closure or closure device for a container and to a container having such a closure or closure device. Background Technology
[0002] This type of closure is typically used to dispense products contained in a container, and the closure is attached to the container.
[0003] The products to be dispensed are typically fluid products, such as liquids or powders or granules, for example in the food or beverage sector, but also in other applications, such as for cleaning substances, detergents or other products.
[0004] The present invention particularly relates to a closure having a flip cover attached to a base element by a hinge, the flip cover being movable between an open position and a closed position, and the flip cover generally rotating about the hinge between its open and closed positions.
[0005] Such closures are known, for example, in EP 2 121 466 B1 or WO 2013 / 023742 A2. Summary of the Invention
[0006] The purpose of this invention is to provide an enhanced closure or closure device and an enhanced system with an enhanced anti-tampering system for indicating whether the flip cover has been opened by the user at least once, or whether it is still in its original, unopened state.
[0007] This objective is achieved through a closure for a container according to the invention and a container with such a closure. The invention also relates to a method for manufacturing such a closure.
[0008] According to the invention, the closure for a container includes a base element and a flap, which is attached directly or indirectly to the base by means of a hinge. This connection or attachment between the flap and the base enables the flap to move between open and closed positions.
[0009] Preferably, the base element has a skirt with an attachment device for attaching the closure to the container. This attachment device may include internal or external threads for interacting with corresponding threads on the container, particularly the neck of the container. The closure may also be a snap-fit closure, including a snap-fit flange for attachment to the container, preferably the neck of the container. However, the closure and container may also be an integral or separate element, and the closure may be attached to the container, preferably the neck of the container, by other fastening methods, such as heating, gluing, or other means.
[0010] The flip cover includes a top cover element and an outer side wall extending from the top cover element.
[0011] In this sense and in conjunction with the description of the closure according to the invention, the closure has a vertical axis or z-axis extending in the vertical direction. If the base element has a generally cylindrical external form or a cylindrical skirt, as is often the case, as shown in the embodiments described later in this specification, this vertical axis or z-axis is also the longitudinal axis of the cylindrical base element or skirt. The upward direction of this vertical axis or z-axis is the positioning direction of the flap, which defines the upper part of the closure, while the downward direction of this vertical axis or z-axis is the positioning direction of the base or base element, defining the lower part of the closure. Therefore, the lower part of the closure is the portion to which the closure is attached or can be attached to the container, while the upper part of the closure is the portion to which the flap is arranged, on the opposite side of the closure to which it is attached or can be attached to the container.
[0012] In addition to this vertical axis, or z-axis, there are two horizontal axes, the x-axis and the y-axis, which are normal to each other and to the vertical axis, or z-axis, thus defining the coordinate system. The y-axis extends through the middle of the closure and through the middle or center of the hinge, while the x-axis extends normally to it. Therefore, when considering a closure with a generally circular shape, the x-axis and y-axis also define the radial direction.
[0013] The closure includes an anti-tampering element for indicating whether the flip cover has been opened by a user at least once, wherein the anti-tampering element is movable between a first position and a second position, and wherein the anti-tampering element is in its first position when the closure is in its manufacturing state or when the flip cover has not yet been opened by a user, and wherein the anti-tampering element is operable by the user to move from its first position to its second position, and simultaneously move the flip cover from its closed position to its open position for the first time.
[0014] According to the invention, the closure element is arranged such that the anti-tampering element is preferably attached immovably (or non-removably) to the flip cover, particularly during normal operation of the device, and is also arranged such that it can be linearly moved from its first position to its second position relative to the flip cover or relative to other parts or specific parts of the flip cover, such as the top cover element or outer sidewall of the flip cover.
[0015] According to the invention, the flap further includes an inner sidewall that extends only around the closure or a portion of the flap's circumference, wherein at least a portion of the inner sidewall and at least a portion of the outer sidewall together form a guide device for enabling the anti-tampering element to move linearly from its first position to its second position and controlling the linear movement of the anti-tampering element from its first position to its second position.
[0016] Furthermore, in its manufactured state or when the flip cover has not yet been opened by a user or is being opened for the first time, the anti-tampering element is brittlely connected to the base element by at least one brittle bridging member spaced apart from each other, preferably by multiple brittle bridging members.
[0017] Furthermore, the anti-tampering element includes a first latching element, and the flip cover includes a second latching element, wherein the first latching element and the second latching element are arranged to hold the anti-tampering element in its second position once the anti-tampering element has been moved to its second position for the first time.
[0018] The advantage of such a closure in the present invention is that the anti-tampering element not only clearly defines the first and second positions, but also clearly defines the movement of the anti-tampering element itself between the first and second positions, which gives any user clearer instructions and feedback.
[0019] In addition, the anti-tampering element is preferably attached to the closure in a non-removable or non-detachable manner, so that it is always kept together with the closure, or more specifically, with the flap of the closure, avoiding separate plastic parts and thus being particularly environmentally friendly.
[0020] In addition, the anti-tampering element is held at or within the flip cover, thus separating it from the base element and the nozzle or dispensing opening at the base element of the closure, so that it does not interfere with the dispensing process.
[0021] Another advantage is that the anti-tampering element is fixed in its first position by a latching element, so that the anti-tampering element does not move after the closure is opened, thereby avoiding any noise or sound that could otherwise be produced in the pocket or the gap of the closure when the anti-tampering element moves, for example after the first opening.
[0022] Furthermore, the anti-tampering element is directly operated by the user when the closure is first opened; in other words, the user can directly manipulate the anti-tampering element. Therefore, the user can move the anti-tampering element out of its initial position, thereby destroying one or more brittle bridging elements that connect the anti-tampering element to the base element in its manufacturing state. Simultaneously, because the user directly operates the anti-tampering element, the user receives more direct feedback regarding the breakage of the brittle connections.
[0023] Through the same operational movement, the user can also move the flip cover from its closed position to its open position. Therefore, the user initiates only one operation, instead of two separate steps or separate activities or movements—one to destroy or remove the anti-tampering element and the other to open the flip cover. The user only needs to initiate one "operational activity," which first automatically destroys the bridging element that attaches it to the base element, moves the anti-tampering element from its first position to its second position, and simultaneously moves the flip cover from its closed position to its open position. Due to the specific arrangement of all the elements, this single "operational activity" initiated by the user is also the movement or "activity" that the user will intuitively apply to open the closure with the flip cover.
[0024] Therefore, even on first-time users, the closure can be intuitively operated, and during the complete operation of opening the flip cover for the first time, the user automatically receives very clear instructions on each step: the breakage of the brittle bridging element, the controlled movement of the anti-tamper element from its first position to its second position, and the initial simultaneous opening of the flip cover. This is a significant enhancement, both relative to the starting and ending positions (the first and second positions) and relative to the movement between these positions, especially compared to closures where the anti-tamper element cannot be directly operated by the user, or at least does not fix all positions of the anti-tamper element at every stage.
[0025] According to a preferred embodiment, the base element has a recessed portion, preferably a radial recessed portion, which extends only around a portion of the circumference of the closure. The recessed portion is arranged such that, when the anti-tampering element is in its first position, the anti-tampering element at least partially extends into the recessed portion of the base element. This arrangement has the advantage that the anti-tampering element is protected within the recessed portion, while the entire closure maintains a monolithic appearance.
[0026] Furthermore, the closure is preferably arranged such that the anti-tampering element retracts at least partially from the recess when it moves from its first position to its second position, making the recess visible or empty, thereby changing the overall appearance of the closure and clearly indicating different states, i.e., indicating that the closure has been opened at least once.
[0027] Preferably, the base element includes a first marking portion disposed in the recessed portion, wherein the first marking portion is arranged such that it is invisible when the anti-tampering element is in its first position, but visible when the anti-tampering element is in its second position. The first marking portion preferably has a mark clearly indicating to the user that the anti-tampering element has been moved; for example, a marking portion engraved with the word "OPEN" may be provided. In addition to its very clear indication effect to the user, this first marking portion is part of the base element, making it clearly visible from any position of the flip cover, which is also a particular advantage. This arrangement also ensures that the size of the flip cover itself can remain relatively small, while maintaining a still relatively large first marking portion by using the available size of the base element. Furthermore, the indication effect is achieved separately from the anti-tampering element itself (in its second position), or, if the anti-tampering element is used alone and / or additionally to indicate that the closure has been opened at least once, there is an additional indication effect at different parts or positions of the closure, which significantly enhances the indication to the user whether the closure has been opened once.
[0028] Preferably, the radially inner surface of the outer sidewall includes a longitudinally extending guide groove, and wherein the radially outer surface of the anti-tampering element includes a protrusion, the guide groove and the protrusion being arranged such that the protrusion at least partially extends into the guide groove, preferably for guiding or controlling linear movement of the anti-tampering element between its first and second positions or for supporting such guidance or control. When considered or viewed with the flap in its closed position, the longitudinal guide groove preferably extends in a vertical direction or along the z-axis. This arrangement further supports controlled movement of the anti-tampering element and also provides greater security against potential manipulation of the anti-tampering element.
[0029] More preferably, the guide groove includes a latching protrusion arranged such that, when the tamper-proof element is in its second position, the latching protrusion interacts with the protrusion of the tamper-proof element (or alternatively, another separate protrusion or element of the tamper-proof element), thereby latching the tamper-proof element in its second position. This arrangement in its second position provides a secure locking of the tamper-proof element, particularly when the locking is provided in the closed internal portion, thus securely preventing further manipulation.
[0030] In a more preferred embodiment, the outer and inner sidewalls of the flap are arranged such that when the flap is in its closed position, the lower edge of one of the outer or inner sidewalls, or the lower edges of both the outer and inner sidewalls, abuts against the base element along the entire circumference of the closure (or at least more than about 90% or at least 80% of the circumference of the closure). This achieves a specific sealing effect, preventing or minimizing the entry of dust or dirt into the area between the flap and the base when the flap is in its closed position, thereby significantly enhancing hygiene in unclean environments.
[0031] In a preferred embodiment, the anti-tampering element includes an actuating protrusion adapted for user operation to move the anti-tampering element from its first position to its second position and move the flip cover out of its closed position upon initial opening of the closure. Preferably, the actuating protrusion extends radially outward from the radially outer surface of the anti-tampering element. More preferably, the actuating protrusion extends along at least 70% of the circumferential extension of the anti-tampering element, preferably at least 80% or even at least 90% of the circumferential extension. This implementation enhances user operability, making it easier for the user to directly operate the anti-tampering element and enhancing feedback during operation, particularly during the initial opening of the flip cover.
[0032] More preferably, the actuating protrusion is arranged such that, when in its second position, it abuts against the lower edge of the outer wall of the flap. This also enhances the controlled movement of the anti-tampering element, particularly its controlled movement to the second position, thereby further enhancing the controlled latching of the anti-tampering element when moved to its second position. Preferably, the lower edge of the outer wall and the edge or boundary or upper portion or vertical upper end of the actuating protrusion have a consistent form, such that they abut against the entire or substantially the entire extension of the actuating protrusion.
[0033] In a particularly preferred embodiment, the flap includes a through-hole, opening, or slit arranged such that, when the anti-tampering element is in its second position, the anti-tampering element at least partially passes through or extends beyond the slit, through-hole, or opening, and when the anti-tampering element is in its first position, the anti-tampering element does not extend through the slit. Such a slit is preferably provided in the top cover element of the flap, but it is also possible for the slit to extend at least partially into the outer wall of the flap. Alternatively, there may be embodiments in which there is a continuous transition between the top cover element and the outer wall of the flap, for example, at a curved edge between the top cover element and the outer wall. In one embodiment, the slit or through-hole may also be arranged wholly or partially in such a transition region, particularly at the curved edge between the top cover element and the outer wall.
[0034] This arrangement provides the user with a particularly clear indication that the anti-tampering element is located in its second position, clearly indicating that the brittle bridging element has been damaged and that the closure has been, or may have been, opened at least once. A very important advantage is that the anti-tampering element extends through the slit to the outside or top, beyond the outer surface of the flip cover, particularly beyond the outer surface of the top cover element or the outer side wall, or beyond the outer surface of the transition area or edge between the two elements. The anti-tampering element is clearly visible from all sides, for example, when viewing the closure from the back where the hinge is arranged.
[0035] Another advantage is that the anti-tampering element can be felt or sensed with the fingers even when it extends beyond the outer surface of the flip cover, which is a particular advantage for blind or visually impaired users.
[0036] It must be mentioned in this regard that, in certain embodiments, the anti-tampering element may extend into the slit or through-hole even in its first position, but it only extends into the inner region of the slit within the thickness of the flip material, and does not extend beyond the outer surface of the flip, or in other words, beyond the size of the slit itself.
[0037] In another alternative embodiment, the flip cover further includes a slit, but the slit is arranged such that when the anti-tampering element is in its second position, the anti-tampering element at least partially extends into the slit but does not pass through the slit, and when the anti-tampering element is in its first position, the anti-tampering element does not extend into the slit. Alternatively, the flip cover further includes a slit arranged such that the anti-tampering element moves closer to the slit without extending into or through the slit when moving from its first position to its second position.
[0038] In these embodiments, independent of the position of the anti-tampering element and even in the second position, the anti-tampering element does not extend through the slit and not beyond the outer surface of the flip cover, or in other words, beyond the slit size itself. However, since the anti-tampering element extends into the slit or into the area within the thickness of the flip cover material (not extending through the slit and into the outer area or beyond the outer surface of the flip cover) or at least closer to the slit when in its second position, the anti-tampering element is significantly more visible in its second position compared to when it is in its first position. In a more preferred embodiment, this visibility can be further increased by implementing an anti-tampering element in a specific color that differs from the color of other parts of the flip cover. For example, the flip cover can be white or gray, while the anti-tampering element can be red.
[0039] In a more preferred embodiment of the closure with a slit in the flap, the anti-tampering element includes at least one additional latching element that interacts with one or more parts of the flap, preferably with one or more parts of the top cover element (or the outer wall or the transition or edge region between the top cover element and the outer wall), such that a latching effect or additional latching effect is achieved, latching or holding the anti-tampering element in its second position once it has first moved to its second position. This arrangement additionally ensures that any manipulation of the anti-tampering element is avoided.
[0040] In another embodiment, the top cover element of the flip cover (or a portion of the outer wall or the transition area or region between the top cover element and the outer wall, e.g., a curved edge) includes a deepening portion or recess extending on a portion of the top cover element. In the flip cover as described above, particularly in embodiments where a slit is included in the top cover element of the flip cover, the slit is preferably entirely disposed within the deepening portion or recess. This ensures that when the anti-tampering element is in its second position, those portions of the anti-tampering element extending beyond the slit are still partially protected by the other portions of the closure or, in particular, the flip cover, while remaining clearly visible or reasonably identifiable.
[0041] In a more preferred embodiment, the top cover element of the flip cover includes at least one, preferably two, flat surfaces forming a standing surface or platform, for allowing the closure or the container connected to the closure to be arranged in an inverted position. This implementation is particularly important for specific products to be dispensed from the container, for example not only in the food and beverage sector, but also in other sectors such as cosmetics or beauty care.
[0042] In embodiments where the flap is provided with an anti-tampering element extending at least partially through a slit, the closure is preferably arranged such that the anti-tampering element, when in its second position, does not extend beyond the plane defined by the flat surfaces of at least one, preferably both, of the top cover element. This ensures that the closure, or the container with the closure, can still be stored or placed in its upper position, even when the anti-tampering element is in its second position.
[0043] According to another embodiment, this varying depth or recess of the flip cover has the form of a groove that extends radially over the entire top cover element, preferably along a direction from the circumferential position of the hinged closure to the circumferential position of the opposite hinge of the closure, such that this groove or recess extends substantially parallel to the y-axis. This implementation makes the anti-tampering element particularly visible from the back of the closure in its second position and when extending through the slit.
[0044] According to a more particularly preferred embodiment, a portion of the inner sidewall and a portion of the outer sidewall together form a channel in which the guide device and the anti-malfunction element can move, wherein at least one bridging element connecting the inner and outer sidewalls is provided in the channel, and wherein the anti-malfunction element has at least one corresponding additional slit, the at least one bridging element extending through the at least one corresponding additional slit. The thickness of this channel is adapted to the thickness of the anti-malfunction element, such that the anti-malfunction element is guided to move substantially only linearly in the longitudinal direction between its first and second positions, avoiding or minimizing movement in other directions. This further ensures proper functioning, particularly proper and controlled movement of the anti-malfunction element within the channel, and it also provides additional protection against any possible manipulation of the anti-malfunction element and the closure.
[0045] According to a more preferred embodiment, the anti-tampering element includes a second marking portion disposed on the radially outer surface of the anti-tampering element, such that the second marking portion is visible when the anti-tampering element is in its first position, and invisible and covered by the outer wall of the flap when the anti-tampering element is in its second position. This provides the user with further identification, additionally ensuring that the user always understands the state of the closure regardless of which direction the user looks at the device from.
[0046] The present invention also relates to a volume having the aforementioned closure and a method for manufacturing the closure, wherein, preferably, the base element and the flip cover are manufactured by injection molding in the open state, with the flip cover in its open position.

[0057] Figure 1 An embodiment of the closure 10 is shown, which has a base element 100 and is connected by a hinge (150, see...). Figure 5 A flip cover 200 is attached to the base element 100. The flip cover 200 includes a top cover element 220 and an outer side wall 240 extending from the top cover element 220.
[0058] A transition or edge portion 230 is curved between the top cover element 220 and the outer side wall 240, which in this embodiment extends around the entire circumference of the closure 10. The top cover element 220 also includes a variable depth portion or recess 224 that extends like a groove along the entire radial extension of the top cover element 220, starting from the region on the opposite side of the hinge (along axis a), such that the recess 224 forms a groove that extends in a direction perpendicular to the axis of rotation around which the flap 200 moves from its closed position to its open position (parallel to the x-axis).
[0059] The top cover element 220 includes two flat surfaces 222, one on each side of the groove or recess 224, which can be used as standing surfaces in case the closure or the container attached to it must be stored or placed in an inverted position.
[0060] from Figure 1 As can be clearly seen, the top cover element 220 includes a slit 300 when the anti-tampering element 400 is in its second position (see [reference]). Figure 2 The components of the anti-tampering element 400 can extend to the outside through the slit 300. However, in Figure 1 In this embodiment, the anti-tampering element 400 is in its first position such that the anti-tampering element 400 will not pass through the slit 300. The slit 300 is curved and extends around a portion of the circumference and substantially spans the entire width of the recess 224; however, in this embodiment, the slit 300 is only located in the area where the indentation is provided, and not in the area of the two flat surfaces 222.
[0061] The base element 100 may be directly or indirectly connected to the container (not shown), and the base element 100 includes an outer side wall 140. The dimensions of the base element 100 and the flap 200 are selected such that the outer surfaces of the outer side walls 140 and 240 have the same outer diameter and are therefore flush with each other.
[0062] In the region opposite to the position where the hinge is located, the base element 100 includes a recess 120 that extends only around a portion of the circumference of the closure; in this embodiment, the recess 20 extends at an angle of approximately 80°.
[0063] The closure 10 includes an anti-tampering element 400, which, relative to the flip cover, is as follows: Figure 1 The first position shown and as Figure 2 The second positions shown are linearly movable. The anti-tampering element 400 shown includes an actuating protrusion 410, which the user operates to move the anti-tampering element 400 from its first position to its second position. A groove or recess 175 is located in the base element 100 below the recess 120 (see in particular). Figure 2 This allows the user to more easily access the actuation protrusion 410 used to operate the device.
[0064] from Figure 1 As can be clearly seen, the anti-tampering element 400 extends substantially completely into the recess 120 of the base element 100, thereby covering a portion of the recess 120 in the view; in this embodiment, it substantially covers the entire recess 120 in the view. The anti-tampering element 400 has a second marking 422 on its outer side, in this embodiment engraved with the word "closed." When the anti-tampering element 400... Figure 1 When shown in its first position, this second identifier 422 is fully visible.
[0065] The anti-tampering element 400 is brittlely connected to the base element 100 via a brittle bridge 402.
[0066] Figure 2 and 3 It shows Figure 1 The embodiment is shown, but with an anti-tampering element 400 that moves to its second position. It can be clearly seen that when the anti-tampering element 400 has moved out of its first position, the brittle bridge 402 has been destroyed.
[0067] The anti-tampering element 400 has been removed from the recess 120 of the base element 100, making the first marking portion 122 of the base element 100 visible. When in its first position, the first marking portion 122 was covered by the anti-tampering element 400. In this embodiment, the first marking portion 122 displays the word "open". The second marking portion 422 on the outside of the anti-tampering element 400, bearing the word "closed", is now covered by the outer wall 240 of the flap 200 and is therefore no longer visible.
[0068] Besides the damaged brittle bridging element 402, the visible first marking 122, and the word "open," the different "states" of the closure become particularly clear because the anti-tampering element 400 now also extends outward through the slit 300 at the top cover element 220 of the flip cover 200. This extension of the anti-tampering element 400 to the exterior of the upper region of the flip cover 200 is not only clearly visible from almost all directions but can also be felt by the user's fingers, which is especially useful for blind or visually impaired individuals.
[0069] However, from Figure 3 As can be clearly seen, the anti-tamper element 400 extends through the slit only to the height of the plane defined by the two flat surfaces 222 of the top cover element 220 or the flip cover 200. Its advantage is that the closure or system with the closure, as well as the container, can still be placed or stored in an inverted position without affecting the anti-tamper element 400.
[0070] Figure 4 It shows Figures 1 to 3 The illustrated embodiment is a perspective view of the state after it has been (injected) molded directly into the open state during the manufacturing process and before the first closing of the flap. Therefore, Figure 4 The position of the anti-tampering element 400 in the recess 120 of the base element 100 is shown very well.
[0071] The anti-tampering element also includes a first latching element, such as a protrusion 482, which is movable within a corresponding guide groove 242 disposed in the radially inner surface of the outer side wall 240 of the flap 200. The longitudinally extending guide groove 242 includes a latching protrusion 282, arranged such that when the anti-tampering element 400 is in its second state, the latching protrusion 282 interacts with the corresponding protrusion 482 of the anti-tampering element 400, the protrusion 482 acting as the first latching element. Therefore, once the anti-tampering element 400 is moved by the user to this second position, the anti-tampering element 400 is attached into its second position.
[0072] The anti-tampering element 400 in this embodiment includes two longitudinally extending additional slits 452, 454 (extending substantially parallel to the z-axis), whose functions will combine Figure 5 Describe it.
[0073] The base element 100 includes a dispensing opening 710, while the flip cover 200 includes an extension 810 and an outer ring 820 on its inner side. When the flip cover 200 is in its closed position, the extension 810 is inserted into the dispensing opening 710 of the nozzle 700, and the outer ring 820 surrounds the nozzle 700.
[0074] Figure 5 It shows Figure 4 An embodiment of the closure is shown, but in a top view. Figure 5 The structure of the flip cover 200 is shown in particular, while the other side, which is basically opposite to the side where the hinge 150 is arranged (in) Figure 5 At the right side, the flap 200 includes another inner sidewall 260, which, together with a portion of the outer sidewall 240, forms a channel 310 between the outer sidewall 240 and the inner sidewall 260 for guiding and controlling the movement of the anti-tampering element 400. The thickness of the channel 310 is adapted to the thickness of the anti-tampering element 400, such that the anti-tampering element 400 is guided to move substantially only linearly in the longitudinal direction between its first position and its second position, avoiding or minimizing movement in other directions.
[0075] In channel 310, there are two bridging elements 252 and 254 that bridge the radially inner surface of the outer sidewall 240 and the radially outer surface of the inner sidewall 260. These two bridging elements 252 and 254 additionally guide the anti-tampering element 400 having corresponding additional slits 452 and 454. Figure 4 This can be clearly seen in the text.
[0076] However, bridging elements 252 and 254 not only serve as additional control and guidance for the anti-tampering element 400 within the channel 310, but also ensure that the thickness of the channel 310 remains substantially constant throughout its entire extension or for most of its extension, even when external pressure should be applied. This further ensures proper functioning, particularly proper and controlled movement of the anti-tampering element 400 within the channel 310, and it also provides additional protection against any possible manipulation of the anti-tampering element 400 and the closure 10.
[0077] Figure 6 and Figure 7 A partial cross-section of an embodiment of the closure is shown, wherein Figure 6 The anti-tampering element 400 is shown in its first position, while Figure 7 The anti-tampering element 400 is shown in its second position.
[0078] It is possible Figure 6 As can be clearly seen, when the anti-tampering element 400 is in its first position and connected to the base element 100 (not visible in this figure) via a brittle bridge, preventing it from moving out of its position without damaging the brittle bridge, the flap 200 is held in its position by the interaction between the protrusion 482 of the anti-tampering element and a portion of the outer sidewall 240, i.e., the end of the guide groove 242 of the outer sidewall 240, wherein the protrusion 482 extends therein and when the anti-tampering element 400 moves from its first position ( Figure 6 Move to its second position ( Figure 7 When the protrusion 482 is in motion, it can move therein.
[0079] Figure 7 It shows and Figure 6 The same cross-section, however, with an anti-tamper element 400 in its second position. It can be... Figure 7 As can be clearly seen, the protrusion 482 of the anti-tampering element 400 is close to the upper end of the guide groove 242 and is held in this position by a latch / by interaction with the corresponding latching element of the flip cover 200.
[0080] Figure 7 It also clearly shows how the anti-tamper element 400, which is in its second position, extends to the outside through the slit 300.
[0081] Figure 8 Another embodiment of the closure of the present invention is shown, which is similar to... Figures 1 to 7 The embodiments shown are very similar. Therefore, similar or identical elements are indicated by the same reference numerals, and descriptions are provided beforehand to avoid repetition.
[0082] Unlike the embodiments shown in the foregoing figures,Figure 8 The embodiments described herein have a different anti-tampering element 400, which has only one radial slit (instead of two slits as in the first embodiment). However, the function is similar, and this additional slit 452 also engages with a corresponding bridging element disposed in the channel between the outer sidewall 240 and the inner sidewall 260 of the flap 200. Therefore, in this embodiment, only one bridging element is disposed in the channel between the outer sidewall 240 and the inner sidewall 260, positioned to match the additional slit 452.
[0083] Furthermore, unlike the first embodiment, the anti-tampering element includes two protrusions 482 and 484 on the radially outer side of the anti-tampering element 400 (instead of one protrusion in the first embodiment), and the outer side wall 240 includes two corresponding guide grooves 242 and 244 on its radially inner surface for guiding and controlling the linear movement of the anti-tampering element 400.
[0084] Figure 9 Another embodiment of the closure element of the present invention is shown, which is similar to... Figure 8 The embodiments shown are very similar. Therefore, similar or identical elements are indicated by the same reference numerals, and descriptions are also mentioned beforehand to avoid repetition.
[0085] In this embodiment, the anti-tampering element 400 does not include any slits, and therefore no corresponding bridging element is provided in the channel between the outer side wall 240 and the inner side wall 260 of the flip cover 200. Other aspects of this embodiment are similar to... Figure 8 The embodiments shown are the same.
[0086] Experts clearly understand that various modifications can be made to the embodiments without departing from the scope of the invention as defined by the appended claims, and that any feature disclosure related to the embodiments or the general description is important for implementing the invention, whether alone or in any combination thereof.
