Description

Technical Field

[0001] The present invention relates to a closing device for closing the mouth of a container having a first locking surface, comprising a closing plug and a safety member. The closing plug has a base body. The safety member is held in a first position via a holding mechanism forming a predetermined breaking point. The safety member has a second locking surface for locking with the first locking surface of the container. The closing device is configured to break the holding mechanism at the predetermined breaking point when the closing device is opened for the first time. The present invention also relates to a container having such a closing device and a method for manufacturing such a closing device. Background Art

[0002] Closing devices with safety members can identify whether the closing device has been opened, especially in the fields of food and drug packaging, but such closing devices can also be reasonably applied to the packaging of other items. Such closing devices can also be called anti-counterfeiting and anti-tampering closing devices.

[0003] Patent document DE19633495A1 describes a closing device for closing the mouth of a container, which has a sealing plug and a safety ring. The safety ring is connected to the sealing plug via a predetermined breaking bridge. In addition, the locking protrusion protruding inwardly in the safety ring is reversely buckled on the surrounding protrusion outside the container wall. When the closing device is opened for the first time, the predetermined breaking bridge will break and the safety ring will be separated from the closing device plug. Summary of the Invention

[0004] The object of the present invention is to provide a closing device for closing the mouth of a container, which has a reliable safety function and the operability of the closing device is improved. The object of the present invention also lies in providing a container having a closing device with a reliable safety function and a manufacturing method thereof, wherein the operability of the closing device is improved.

[0005] The solution of the present invention to achieve the above object is the feature of claim 1. A closing device for closing the mouth of a container having a first locking surface according to the present invention comprises a closing plug and a safety member. The closing plug has a base body. The safety member is held in a first position via a holding mechanism forming a predetermined breaking point. The safety member has a second locking surface for locking with the first locking surface of the container. The closing device is configured to break the holding mechanism at the predetermined breaking point when the closing device is opened for the first time. The safety member is connected to the base body in a constrained manner via one or more hinge segments.

[0006] This closure device with a safety element allows to identify whether the closure device has been opened. Since the first opening of the container necessarily causes the retaining element to break at a predetermined breaking point, it is easy to determine whether the container is still sealed or has been opened. Before the closure device is applied to the container and before the closure device is first opened, the second locking surface of the safety element can be locked with the first locking surface of the container. In this way, a form fit can be achieved between the elements of the closure device (especially the safety element) and the container. This form fit can be used to ensure that the closure device can only be opened by releasing the retaining mechanism. The form fit can be achieved, for example, by moving the second locking surface past the first locking surface when applying the closure device until the second locking surface is locked with the first locking surface. For this purpose, it can be proposed that the second locking surface and the first locking surface are arranged corresponding to each other. In the closed position before the closure device is first opened, that is, in the first position of the safety element when the retaining mechanism is still intact, the second locking surface can interact with the first locking surface so that a form fit is formed between the safety element and the container. In the first position of the safety element, the closure device is fixed to the container. Due to the form fit formed between the safety element and the container, the closure device cannot be removed from the container without disconnecting the retaining mechanism. The safety element can have one or more second locking surfaces. In this way, a form fit can be formed with the container at multiple locations, thereby further enhancing the safety function. In the first position of the safety element, the applied closure device is fixed to the container. After the retaining mechanism is disconnected, the safety element can move to the second position. In the second position of the safety element, the second locking surface of the safety element and the first locking surface of the container are not locked with each other, and the closure device can be removed from the container. By connecting the safety element and the base body via a hinge section, the safety element and the base body and thus the safety element and the sealing plug are connected in a bound manner. This bound connection exists in both the first position and the second position of the safety element. Through this bound connection, at the end of the expected service life of the closure device, the safety element and the sealing plug can be easily disposed of properly as a complete closure device. Therefore, the closure device also contributes to environmental protection because the safety element will not accidentally fall off into the environment. Taking these measures will also enhance the safety function, and only simple handling of the closure device is required, which is more convenient for disposal. Even when mass-producing the closure device, economic efficiency can be guaranteed, and at the same time, process reliability can be improved, which is especially attributed to the fact that the closure device can be manufactured by an injection molding process as a plastic component. In addition, the closure device can also achieve good sealing performance. Therefore, the closure device is widely applicable to various applications, especially for containers filled with humidity-sensitive items (such as food, nutritional supplements, drugs, chemicals, and / or test strips, etc.). After the first opening, the closure device can be repeatedly closed and opened. In this way, the contents of the container can be taken out one by one. The closure device can be connected to the container in a force fit and / or form fit manner to fix the closure device to the container.To achieve a form - locking connection, the closure plug can have a first thread, and the container can have a second thread complementary to the first thread in order to fix the closure device to the container via a threaded connection. The sealing plug can have different configurations to ensure a reliable seal.

[0007] Preferably, the hinge section is configured as a plastic - film hinge.

[0008] Advantageously, it can be proposed that the locking element has a first side and an opposite second side, wherein the locking element has a mounting ramp on its inner side, and wherein the mounting ramp widens the inner diameter of the locking element towards the second side. The first side of the locking element can in particular be arranged adjacent to the base body. The second side can in particular face away from the base body. The hinge section connecting the locking element to the base body can preferably be arranged on the first side of the locking element. Since the locking element has a mounting ramp on its inner side, after filling the container, the closure device can be more conveniently applied to the container, and the retaining mechanism remains intact in the first position. The mounting ramp facilitates applying the locking element to the container before the first opening. Therefore, the closure device can be more conveniently applied to the container before the first opening.

[0009] According to an advantageous design of the invention, the base body has a base and a skirt arranged on the base. The skirt can preferably be arranged perpendicular to the base. The skirt is preferably arranged at the edge of the base. Preferably, the skirt surrounds the base. Here, the skirt can have an annular configuration, particularly preferably a circular - annular configuration. This particularly helps to improve operability.

[0010] According to a preferred design of the invention, the hinge section is arranged at the skirt.

[0011] It is also advantageously proposed that the base has a disc - shaped configuration. According to another embodiment, the base can have an annular configuration.

[0012] Advantageously, it can be proposed that the locking element has a surrounding configuration. The locking element can be configured to extend completely or partially to the outer periphery of the base body. Preferably, it can be proposed that the locking element has an annular configuration, preferably a circular - annular configuration. Here, the basic geometry of the locking element preferably corresponds to the basic geometry of the skirt.

[0013] According to a particularly preferred design of the invention, the locking element has a first section and a second section, wherein a dividing line is provided between the first section and the second section. Here, it can be proposed that the locking element is divided into the first section and the second section by the dividing line. The dividing line can be formed by a gap. Here, the dividing line can preferably extend transversely to the circumferential direction of the locking element. The dividing line can also extend at an angle with respect to the circumferential direction of the locking element, in which case the dividing line extends obliquely with respect to the circumferential direction of the locking element. Preferably, the dividing line is designed as a straight line, but the dividing line can also have a curved section. In particular, it is conceivable that the dividing line is designed as wavy.

[0014] According to an embodiment of the present invention, the first section and the second section are not connected to each other within the dividing line area. Advantageously, it can also be provided that the retaining mechanism includes at least one first retaining bridge that connects the first section to the second section. The dividing line or the dividing line configured as a gap is bridged by at least one first retaining bridge. The first retaining bridge forms a predetermined breaking point that can be broken by human force. This can be achieved, for example, in such a way that the closing device is configured to cause the first retaining bridge to break or tear when the closing device is opened for the first time. Thereby, based on the first retaining bridge, it can be determined whether the closing device has been opened at least once. If the first retaining bridge is intact, the closing device has not been removed from the container. If the first retaining bridge is broken, the closing device has been removed from the container at least once. The retaining mechanism can include one or more first retaining bridges. The first retaining bridge can also be configured as a planar sheet that tears when the closing device is opened for the first time. For this purpose, the first retaining bridge can be configured in a film-like manner. If only the first retaining bridge is provided, the first retaining bridge can especially be configured in a film-like manner and extend along the dividing line over most of the dividing line.

[0015] Another embodiment of the present invention provides that the retaining mechanism includes at least one second retaining bridge that connects the base body to the safety element. In addition to the first retaining bridge, at least one second retaining bridge can also be provided. It is also possible to provide only at least one second retaining bridge without providing any first retaining bridges. The second retaining bridge forms a predetermined breaking point that can be broken by human force. This can be achieved, for example, in such a way that at least one second retaining bridge breaks or tears when the closing device is opened for the first time. The second retaining bridge can also be configured as a planar sheet that tears when the closing device is opened for the first time. For this purpose, the second retaining bridge can be configured in a film-like manner. Thereby, based on the second retaining bridge, it can be determined whether the closing device has been opened at least once. If the second retaining bridge is intact, the closing device has not been removed from the container. If the second retaining bridge is broken or torn, the closing device has been removed from the container at least once. The retaining mechanism can include one or more second retaining bridges. Preferably, the retaining mechanism includes more than two second retaining bridges. Particularly preferably, the retaining mechanism includes more than four second retaining bridges. Preferably, the retaining mechanism includes less than twenty second retaining bridges. Particularly preferably, the retaining mechanism includes less than sixteen second retaining bridges. Preferably, the second retaining bridge connects the skirt to the safety element. Particularly preferably, the second retaining bridge connects the skirt to the first side of the safety element.

[0016] According to the present invention, it can be provided that a spacing configured as a slit is provided between the safety element and the base body. If second retaining bridges are provided, these second retaining bridges can be arranged to bridge the slit.

[0017] It can also be proposed that after the closing device is first opened, with the predetermined breaking point of the retaining mechanism being open at this time, the safety element can be arranged to be movable relative to the base body by means of a hinge section. Here, the safety element can be movably arranged on the base body (preferably its skirt) by means of a hinge section. Preferably, the safety element is arranged to pivot in this way after the closing device is first opened. By the movable arrangement of the safety element, the safety element can enter a second position in which the second locking surface of the safety element and the first locking surface of the container are not interlocked. Preferably, the safety element can pivot about the axis of rotation of the hinge section.

[0018] A particularly preferred design of the present invention proposes that the safety element comprises a plurality of safety element segments which are respectively connected to the base body in a binding manner via one of the hinge sections. Here, the safety element segments can be movably connected to the skirt via one of the hinge sections respectively. Preferably, the safety element comprises two to ten safety element segments. In order to form the safety element segments, a dividing line can be provided between two adjacent safety element segments respectively. Here, the safety element segments can form a first section and a second section of the safety element. The dividing line can be formed by a gap. It can be proposed here that the dividing line is bridged by one of the first retaining bridges. The dividing line can be arranged to be distributed on the circumference of the safety element, preferably evenly distributed on the circumference. When the safety element segments are evenly distributed, they can have the same geometric shape. By these measures, the size of the safety element segments is smaller than the size of the safety element, thereby further enhancing the operability of the closing device.

[0019] It can also be advantageously proposed that the safety element segments and the base body are respectively connected via one of the second retaining bridges. Preferably, the second retaining bridge connects the safety element segment to the skirt.

[0020] According to a particularly preferred design of the present invention, each of the safety element segments has one or more second locking surfaces. The second locking surfaces can respectively correspond to the first locking surfaces. In this way, a form-fit can be achieved between the safety element and the container. The operability is further enhanced by these features.

[0021] It can be advantageously proposed that the second locking surface of the safety element is configured as a locking projection. The locking projection corresponds to the first locking surface of the container, and in the closed position of the closing device, a form-fit is achieved between the safety element and the container before the first opening.

[0022] It can also be proposed that the locking projection has an undercut. The undercut strengthens the form-fit between the safety element and the container, making it difficult for the safety element to accidentally disengage from the container.

[0023] The locking projection can have an elastically deformable deformation section by means of the undercut. When assembling the closing device, the deformation section can be deformed, thus simplifying the assembly. This reduces the risk of accidental breakage of the retaining mechanism during assembly.

[0024] Advantageous improvement solutions of the present invention propose that there are multiple locking protrusions. Preferably, the locking protrusions are arranged to be distributed on the circumference of the sealing plug. In this way, form-locking can be achieved at multiple points between the locking member and the container, thereby enhancing the locking performance. Particularly preferably, the locking protrusions are arranged to be evenly distributed on the circumference. Preferably, at least three locking protrusions are arranged to be distributed on the circumference. In this way, uniform form-locking is achieved, improving the process reliability and sealing performance during installation. Preferably, one or more locking protrusions are arranged on each section of the locking member.

[0025] It can also be advantageously proposed that the base has an edge section in which a socket associated with the second locking surface is constructed. Preferably, the edge section is constructed in an annular shape. The edge section can extend along the outer circumference of the base. Preferably, each second locking surface is associated with a socket. The socket can be constructed as an arc section. The tool section for forming the second locking surface can extend through the socket during the following injection molding process. Here, the tool section can be used as part of the female mold for molding the second locking surface and can be removed from the socket during demolding after the injection molding process. The size of the socket preferably corresponds at least to the size of the second locking surface. Preferably, the internal size of the socket corresponds to the external size of the second locking surface. With the help of the socket, complex geometric structures such as undercuts can also be conveniently produced in the injection molding process. In this way, in mass production, the closing device has both good locking function and cost-effectiveness.

[0026] According to a particularly preferred design solution of the present invention, a clamping section is provided at the base for abutting against the inner side of the container. The force-locking connection between the sealing plug and the container can be achieved by using the clamping section. Here, the clamping section can be designed such that the closing device is fixed to the container firmly enough but can still be smoothly removed from the container. Preferably, the clamping section is formed by an annular section arranged at the base. Particularly preferably, the clamping section is annular. When the closing device is not applied, the outer diameter of the clamping section is slightly larger than the inner diameter of the container mouth to achieve the clamping force. Here, the clamping section can be constructed to be elastically deformable, so that the clamping section exerts a clamping effect on the container mouth. This will further enhance the operability of the closing device.

[0027] It is advantageously proposed that the cross-sections of the skirt, the base and the clamping section are arranged in a U-shape. Here, the clamping section can be arranged to be substantially perpendicular to the base and parallel to the skirt and / or the locking member. The clamping section can be arranged on the side of the base where the skirt is arranged.

[0028] It can also be proposed that the clamping section has a sealing section which is arranged on the outer side of the clamping section. The sealing section is constructed to seal against the container in the closed position of the closing device. Through the clamping action of the clamping section, the sealing section can be pressed against the container, thereby enhancing the sealing effect and improving the overall sealing performance of the closing device. Preferably, the sealing section is constructed as an olive-shaped sealing ring.

[0029] According to another advantageous design of the present invention, the clamping section has a guiding inclined surface. The guiding inclined surface can be arranged on the outer side of the clamping section. The guiding inclined surface can be arranged on the side of the clamping section facing away from the base. Through the guiding inclined surface, the outer diameter of the clamping section can be narrowed from the base towards the free end of the clamping section. When the closing device is inserted onto the container, the automatic centering of the closing device relative to the container opening can be achieved through the guiding inclined surface. In addition, the movement of inserting the clamping section into the container opening can be guided, thereby simplifying the insertion. The closing device can slide onto the container more easily. Through these measures, the operability of the closing device is further improved.

[0030] It can also be advantageously proposed that the clamping section is connected to a holding section, and the holding section extends radially inwards from the clamping section. The holding section can stabilize the clamping section, thus contributing to better operation.

[0031] According to the present invention, it can also be proposed that the holding section is arranged on the inner side opposite to the sealing section of the clamping section. In this way, the clamping section can be strengthened, thereby increasing the stiffness, especially in the area of the sealing section. This will further improve the sealing performance.

[0032] Advantageously, it can be proposed that the holding section has an annular structure. In this way, a desiccant chamber can be arranged in the holding section, as described below. The holding section can be arranged concentrically around the desiccant chamber. An advantageous improvement of the inventive concept proposes that the cross-sections of the holding section, the clamping section, and a partial chamber wall of the following desiccant chamber are arranged in a U-shape. Here, the U-shape arrangement forms a circular channel. Through the U-shape arrangement, the stiffness of the clamping section can be enhanced, thereby further improving the sealing performance.

[0033] Advantageously, it can be proposed that the sealing plug can have a desiccant chamber. The desiccant chamber preferably has a cylindrical chamber wall. Preferably, the desiccant chamber is filled with a desiccant such as silica gel. The side of the desiccant chamber facing the container can have a moisture-permeable material. Through the desiccant, the humidity inside the container can be effectively reduced. In this way, even humidity-sensitive substances can be stored in the container for a long time.

[0034] It can also be advantageously proposed that the closing device includes an integrally injection-molded component, and the injection-molded component includes a base body, a safety component, a hinge section, and a holding mechanism. Here, preferably, the injection-molded component further includes a clamping section, a holding section, and / or a desiccant chamber. Through this manufacturing method, both the manufacturing quality can be improved and the unit cost can be reduced at the same time.

[0035] It can also be proposed that the sealing plug has a spring element. By means of the spring element, the object stored in the container can be pressed against the bottom of the container with prestress to prevent the object from being damaged during transportation. The spring element can be arranged at the holding section. Preferably, the spring element includes an annular body and at least one arm body connecting the annular body to the base. Particularly preferably, at least one arm body is arranged in a spiral shape. It can also be advantageously proposed that the skirt has a gripping area with gripping grooves. The gripping grooves provide a contact surface for the fingers (especially the thumb) of the operator of the closing device. In this way, pressure can be applied to the base specifically to separate the closing device from the container and expose the container opening. Preferably, at least one first holding bridge is associated with the gripping area so that when pressure is applied to the gripping area, the first holding bridge breaks and the closing device can be opened. It is not necessary to pre-damage the first holding bridge before opening the closing device. In this way, the operability of the closing device can be further improved.

[0036] Advantageously, it is proposed that the closing device is configured as an anti-rebound closing device. The closing device does not have any threads for connecting to the container. When the closing device is applied to the container, the sealing plug slides along the container wall.

[0037] Advantageously, it can be proposed that the closing device is configured as a screw-type closing device and / or a plug-type closing device. Here, it can be proposed that the sealing plug is configured to abut against the end face of the container and / or extend into the container opening.

[0038] In addition, the solution of the present invention for achieving the above object is a container having a first locking surface and the closing device.

[0039] Preferably, it can be proposed that the container includes a surrounding protrusion, and the surrounding protrusion constitutes the first locking surface. Through the surrounding first locking surface, the second locking surface can engage with the first locking surface at any arbitrary circumferential position of the first locking surface. Preferably, the protrusion is arranged on the outer side of the container. In this way, the closing device can be applied to the container more flexibly, thereby improving the operability. It can also be advantageously proposed that the first locking surface of the container has an additional undercut. Through this additional undercut, the form fit between the securing element and the container is strengthened, making it difficult for the securing element to accidentally disengage from the container. Here, it can be proposed that the first locking surface forms an elastically deformable deformation section due to the additional undercut. During installation, this deformation section will deform, enabling the closing device to be installed more conveniently without damaging the holding mechanism.

[0040] Advantageously, it can be proposed that the container can have a tubular structure. Preferably, the outer diameter of the container is in the range of 10 mm to 75 mm.

[0041] Preferably, the container has a cylindrical structure.

[0042] It can also be proposed that the container is filled with a medical preparation, a pharmaceutical agent, and / or a nutritional supplement.

[0043] The present invention also relates to a method for manufacturing the closing device, wherein the base body of the closing device is manufactured by an injection molding process. Preferably, the injection mold used during manufacturing includes a continuous cavity for accommodating the base body, the safety element, the hinge section, and the retaining mechanism. Here, it is preferred that the injection mold further accommodates the clamping section, the retaining section, and / or the desiccant chamber.

[0044] It can be proposed here that the method may include a demolding step during which the slide of the injection mold is withdrawn through the socket.

[0045] Furthermore, the solution of the present invention for achieving the above object is an injection mold for the closing device. Preferably, the injection mold includes a slide that restricts the locking protrusion and forms a socket during the injection molding process.

[0078] Figure 1 Shows a cross-sectional view of a container 2 having a first locking surface 1 and an enclosed device 3 for closing the mouth of the container 2. The enclosed device 3 is shown in cross-section, but for clarity, Figure 1 the enclosed device 3 is not hatched in. The enclosed device 3 includes an enclosure plug 4 and a safety element 5, where the safety element 5 is held in a first position via a holding mechanism 6 (detailed below) that forms a predetermined breaking point.

[0079] The safety element 5 has a second locking surface 7 for locking with the first locking surface 1 of the container 2. The second locking surface 7 of the safety element 5 is configured as a locking projection 8. The locking projection 8 corresponds to the first locking surface 1 of the container 2, and in the closed position of the closing device 3, a form-fit is formed between the safety element 5 and the container 2 before the first opening. The locking projection 8 has an undercut. The form-fit between the safety element 5 and the container 2 is strengthened by the undercut, so that it is difficult for the safety element 5 to accidentally disengage from the container 2. The locking projection 8 forms an elastically deformable deformation section through the undercut. A plurality of locking projections 8 are provided. These locking projections 8 are arranged evenly distributed on the circumference of the sealing plug 4.

[0080] The container 2 further includes a protruding portion 9 surrounding the outside of the container body 37, wherein the surrounding protruding portion 9 constitutes the first locking surface 1. Through the surrounding first locking surface 1, the second locking surface 7 can engage with the first locking surface 1 at any circumferential position of the first locking surface 1. The first locking surface 1 of the container 2 has an undercut. Through the additional undercut, the first locking surface 1 forms an elastically deformable deformation section.

[0081] Generally, after the container 2 is filled, the closing device 3 is applied to the container 2. During the first application of the closing device 3 to the container 2 in this way, the second locking surface 7 of the safety element 5 moves over the first locking surface 1 of the container 2 until the second locking surface 7 engages with the first locking surface 1 of the container 2. The second locking surface 7 corresponds to the first locking surface 1. In the closed position before the first opening of the closing device 3, that is, when the retaining mechanism 6 is intact in the first position of the safety element 5, the second locking surface 7 and the first locking surface 1 remain in interaction, so that a form-fit is formed between the safety element 5 and the container 2. In the first position of the safety element 5, the closing device 3 is fixed to the container 2. Due to the form-fit formed between the safety element 5 and the container 2, the closing device 3 cannot be removed from the container 2 without disconnecting the retaining mechanism 6.

[0082] The container 2 has a tubular structure and has an outer diameter D1 of the container 2 and an inner diameter D3 of the container mouth. Preferably, the outer diameter D1 of the container 2 is in the range of 10 mm to 75 mm. In the illustrated embodiment, the container has a cylindrical structure and has a container bottom 38 on one side. The container mouth is provided on the opposite side. The parallel wavy lines are break lines, indicating that the container body 37 is shortened for space saving. The geometric shape of the container body 37 remains unchanged between the break lines.

[0083] The container 2 can be filled with, in particular, medical preparations, pharmaceuticals or nutritional supplements (not shown). In particular, two tablets (such as effervescent tablets) or test strips can be arranged in the container.

[0084] Figures 2 to 11 Different views of the first embodiment of the closing device 3 are shown. Therefore, it will be described together below Figures 2 to 11 .Figures 2 to 11 Shows Figure 1 The closure device 3 is also shown, but without the container.

[0085] Figure 2 Shows Figure 1 Side view of the closure device 3 shown. The closure plug 4 has a base 10. The base 10 has a base 11 of an annular structure and a skirt 12 arranged on the base 11. Here, the skirt 12 is especially arranged to be substantially perpendicular to the base 11. The skirt 12 is arranged at the edge of the base 11 and extends to the side of the closure device 3 facing the container 2. In addition, the skirt 12 is in a surrounding annular structure. The closure device 3 has a clamping section 13 at the base 11 for abutting against the inner side of the container 2. The clamping section 13 can be used to achieve a force-locking connection between the sealing plug 4 and the container 2. The clamping section 13 is formed by a circular ring section arranged on the base 11. When the closure device 3 is not applied, the outer diameter D2 of the clamping section 13 is slightly larger than the inner diameter D3 of the container mouth. The clamping section 13 can be elastically deformed, so that the clamping section 13 achieves a clamping effect on the container mouth. Figure 1 (and Figure 10 and Figure 11 ) shows that both the clamping section 13 and the container 2 are in an undeformed state. This represents an overlap area between the container 2 and the clamping section 13, which does not exist in the actual product. The difference between the diameter D1 and the diameter D3 leads to deformation and thus prestress. Alternatively, it is conceivable that the closure device 3 is designed as a screw-type closure device and can be fixed to the housing via a screw connection.

[0086] The cross section of the skirt 12, the base 11 and the clamping section 13 is arranged in a U-shape. The clamping section 13 is arranged substantially perpendicular to the base 11 and parallel to the skirt 12 and the safety element 5. The clamping section 13 is arranged on the side of the base 11 where the skirt 12 is arranged.

[0087] The clamping section 13 has a sealing section 14 which is arranged on the outside of the clamping section 13. The sealing section 14 is configured to seal against the inside of the container 2 in the closed position of the closure device 3.

[0088] The clamping section 13 has an introduction bevel 15. The introduction bevel 15 is arranged on the outer side 84 of the clamping section 13. The introduction bevel 15 is arranged on the side of the clamping section 13 facing away from the base 11. The introduction bevel 15 narrows the outer diameter D2 of the clamping section 13 from the base 11 toward the free end of the clamping section 13.

[0089] The clamping segment 13 is connected to an annular retaining segment 16 which extends radially inwards from the clamping segment 13. The retaining segment 16 closes the inner passage of the clamping segment 13 and is arranged on the inner side of the clamping segment 13 in the region of the sealing segment 14.

[0090] The closing plug 4 has a desiccant chamber 17. In the illustrated embodiment, the desiccant chamber 17 has a cylindrical chamber wall. The desiccant chamber 17 is filled with a desiccant (not shown), especially silica gel. The side of the desiccant chamber 17 facing the container 2 can be covered with a cover (not shown) made of a moisture-permeable material such as cardboard.

[0091] The cross-section of the holding section 16, the clamping section 13, and a partial chamber wall of the desiccant chamber 17 is arranged in a U-shaped configuration. Here, the U-shaped configuration forms a circular channel 18.

[0092] The safety element 5 has a surrounding circular ring-shaped structure and extends substantially around the outer circumference of the base body 10. The safety element 5 is configured to have the same geometric profile as the skirt 12 of the base body 10.

[0093] The safety element 5 has a first side 19 and an opposite second side 20. The first side 19 is adjacent to the base body 10, while the second side 20 faces away from the base body 10 and thus towards the container 2. The safety element 5 has an installation inclined surface 21 associated with the second locking surface 7 on its inner side, where the inner diameter D4 of the safety element 5 widens towards the second side 20 (starting from the second locking surface 7) by means of the installation inclined surface 21. With the aid of the installation inclined surface 21, the safety element 5 can be more conveniently applied to the container 2 in the first position.

[0094] The closing plug 4 has a spring element 24. The spring element 24 is arranged at the holding section 16. The spring element 24 includes a ring body 25 and four arm bodies 26. The arm bodies 26 are arranged in a spiral shape. The spring element can prestress the object stored in the container towards the bottom of the container to prevent the object from being damaged during transportation.

[0095] The closing device 3 includes an injection-molded part. The injection-molded part includes a base body 10, a safety element 5, a holding mechanism 6 (not shown in this figure), and a hinge element 27. In addition, the injection-molded part includes a clamping section 13, a holding section 16, a spring element 24, and a desiccant chamber 17.

[0096] The closing device 3 is configured as an anti-rebound closing device. The closing device 3 does not have any threads for connecting to the container 2. When the closing device 3 is applied to the container 2, the closing plug 4 slides along the container wall.

[0097] Especially as Figures 3 to 9 As shown, the safety element 5 includes a plurality of safety element segments 32. These safety element segments 32 are each bound and connected to the skirt 12 of the base body 10 via a hinge section 27. In the illustrated embodiment, the safety element 5 includes six safety element segments 32. Alternatively, the safety element 5 can have a different number of safety element segments 32, especially two to ten safety element segments 32.

[0098] In order to construct the insurance part segments 32, a dividing line 30 is constructed between two adjacent insurance part segments 32. The dividing lines 30 are all composed of gaps. Each dividing line 30 is bridged by one of the first holding bridges 31. The dividing lines 30 are arranged to be evenly distributed on the circumference of the insurance part 5. The insurance part segments 32 have the same geometric shape.

[0099] Figure 3 shows Figure 1 A front view of the shown closing device 3 is presented. This figure shows that the insurance part 5 is boundedly connected to the base body 10 via a plurality of hinge segments 27. The connection between the insurance part 5 and the base body 10 via the hinge segments 27 ensures the boundedly connected relationship between the insurance part 5 and the sealing plug 4. The hinge segments 27 are constructed as thin-film hinges.

[0100] The first holding bridge 31 connects the first section 28 and the second section 29. In the shown embodiment, two holding bridges are provided between the first section 28 and the second section 29. The dividing line 30 constructed as a gap is bridged by the first holding bridge 31. The first holding bridge 31 forms a predetermined breaking point that can be broken by human force. When the closing device 3 is opened for the first time, the first holding bridge 31 must be disconnected. Thereby, based on the first holding bridge 31, it can be determined whether the closing device 3 has been opened at least once. If the first holding bridge 31 is intact, the closing device 3 has not been removed from the container 2. If the first holding bridge 31 is broken, the closing device 3 has been removed from the container 2 at least once. The holding mechanism 6 includes a plurality of first holding bridges 31.

[0101] As Figure 3 shown, the skirt 12 has a gripping area 33 with a gripping groove 34. The gripping groove 34 provides a contact surface for the operator's finger (especially the thumb) of the closing device 3. One of the first holding bridges 31 is associated with the gripping area 33 so that when pressure is applied to the gripping area 33, the first holding bridge 31 breaks and the closing device 3 can be opened. The gripping groove 34 in the gripping area 33 is configured as a groove in the skirt 12. Figure 4 and Figure 5 show a rear view and a right view of the closing device 3.

[0102] Figure 6A perspective view of the closure device 3 is shown. As can be clearly seen from this figure, the base 11 has an edge section 35 in which sockets 36 are configured. These sockets 36 are each associated with a second locking surface 7 (not shown in this figure). The edge section 35 is configured in an annular shape and extends on the outer periphery of the base 11. The sockets 36 are configured as arc segments. The dimensions of the sockets 36 correspond to the dimensions of the associated second locking surface 7. Tools for forming the second locking surface 7 during the injection molding process are arranged in the sockets 36. This tool serves as a female mold for molding the second locking surface 7, and after the injection molding process, this tool is removed through the sockets 36 so as to be removed from the closure device 3. On the side of the closure device 3 opposite to the spring member 24, a flat surface for accommodating a graphic label is provided in the central area.

[0103] Figure 7 A simplified top view after the closure device 3 is first opened is shown. After the retaining mechanism is disengaged, the locking piece segment 32 is arranged in a manner that can move relative to the base body 10 by means of the hinge segment 27 and pivots outwards. By deflecting the locking piece segment 32, the locking piece segment 32 can enter a second position, in which the second locking surface 7 (not shown in this figure) of the locking piece segment 32 and the first locking surface 1 of the container 2 are not engaged with each other. In this position, the closure device can be removed from the container and reattached.

[0104] Figure 8 Shows Figure 7 An oblique top perspective view of the shown closure device 3, in which the locking piece segment 32 is pivoted to the second position. As can be clearly seen from the figure, the locking piece segment 32 pivoted outwards. Figure 9 Shows Figure 7 An oblique bottom perspective view of the shown closure device 3 and the locking piece segment 32 after pivoting. Figure 9 Shows that each locking piece segment 32 can have two second locking surfaces 7. Each second locking surface 7 can correspond to the first locking surface 1 of the container 2, and the first locking surface 1 is configured as a surrounding locking projection 9.

[0105] Figure 10 Shows Figure 1 A detailed cross-sectional view of the shown closure device 3 and the container 2 is shown. The closure device 3 is shown in section, but for clarity, Figure 10 the closure device 3 is not hatched in the figure. The locking piece 5 is held in the first position such that the second locking surface 7 and the first locking surface 1 of the container 2 are engaged. The second locking surface 7 corresponds to the first locking surface 1 such that a form-fit is formed between the locking piece 5 and the container 2. In the first position of the locking piece 5, the closure device 3 is fixed to the container 2, and due to the form-fit formed between the locking piece 5 and the container 2, the closure device 3 cannot be removed from the container 2 without disengaging the retaining mechanism 6.

[0106] Figure 11 ShowsFigure 1 Detail cross-sectional view of the closure device shown and the container 2 after the retaining mechanism has been disengaged. As a result, the locking element segment 32 can pivot outwards (into the second position). The closure device 3 is shown in section, but for clarity, Figure 11 it is not hatched in the figure. The locking element 5 is no longer fixed by the retaining mechanism, so that the second locking surface 7 no longer engages with the first locking surface 1 of the container 2. There is no longer a form-fit between the locking element 5 and the container 2. In the second position of the locking element 5, the closure device 3 is not fixed to the container 2 and can be removed from and reattached to the container 2.

[0107] Figures 12 to 19 Another embodiment of the closure device 3' is shown. This closure device is Figures 1 to 11 highly similar to the closure device 3 shown. Therefore, similar parts are labeled with the same reference numerals. Figures 1 to 11 The relevant description of Figures 12 to 19 also applies to

[0108] unless otherwise stated below. Figure 1 The closure device 3' can be used for

[0109] the container 2 shown. Figures 1 to 11 The difference between the closure device 3' and

[0110] Figure 12 Another front view of the closure device 3' (without the container 2) is shown. The closure device 3' has only one dividing line 30, so that the locking element 5 is not divided into a plurality of locking element segments 32. However, the locking element 5 has a first section 28 and a second section 29, between which a dividing line 30 is provided. The locking element 5 is divided along the dividing line 30. The dividing line 30 is formed by a gap. The dividing line 30 extends transversely to the circumference of the locking element 5. Alternatively, the dividing line 30 can also extend at an angle to the circumference of the locking element. The dividing line 30 is designed as a straight line. Alternatively, the dividing line 30 can also have a curved section. It is especially conceivable that the dividing line 30 has a wavy design.

[0111] The locking element 5 is constructed circularly (except for the dividing line 30). In the middle section where the first section 28 and the second section 29 extend, the locking element is connected to the hinge section.

[0112] The safety element 5 is also held in the first position via a retaining mechanism 6 that forms a predetermined breaking point, and the retaining mechanism 6 breaks when the closing device 3' is opened for the first time. The retaining mechanism 6 includes at least one second retaining bridge 22. The second retaining bridge 22 forms a predetermined breaking point and can be broken by hand. The second retaining bridge 22 connects the skirt 12 of the base body 10 to the first side 19 of the safety element 5. The safety element 5 is spaced apart from the base body 10 by a distance that is configured as a slit 23. The slit 23 is bridged by the second retaining bridge 22. When the closing device 3' is opened for the first time, the second retaining bridge 22 breaks. Thereby, it can be determined based on the second retaining bridge 22 whether the closing device 3' has been opened at least once. If the second retaining bridge 22 is intact, the closing device 3' has not been removed from the container 2. If the second retaining bridge 22 is broken, the closing device 3' has been removed from the container 2 at least once. As shown in the figure, the retaining mechanism 6 includes a plurality of second retaining bridges 22, and these second retaining bridges 22 are arranged to be distributed on the circumference of the safety element 5.

[0113] Figure 13 A rear view of the closing device 3' is shown. From this figure, the continuous safety element 5 and the hinge section 27 can be seen.

[0114] Figure 14 A perspective view of the closing device 3' is shown. From this figure, the socket 36 can also be clearly seen.

[0115] Figures 15 to 17 The closing device 3' after the retaining mechanism breaks during the first opening is shown. Accordingly, the safety element 5 pivots outwards and clearly indicates that the closing device 3' has been opened.

[0116] As Figure 27 shown, the safety element 5 of the closing device 3' is in the second position. The closing device 3' has a larger angle between the skirt 12 and the safety element 5, and the safety element 5 is connected to the skirt 12 via the hinge section 27. This angle is slightly larger than the angle in Figures 15 to 17 . Thereby, especially in the region arranged opposite to the hinge section 27 (below the catch groove 34 not shown in this figure), the skirt 12 and the safety element 5 are spaced apart. In this second position where the safety element 5 is further deflected, the closing device 3' can be removed from the container 2 more conveniently.

[0117] Figure 27a A detailed view showing the safety element 5 connected to the skirt 12 via the hinge section 27 is shown. The hinge section 27 is configured as a thin film hinge, enabling relative movement between the safety element 5 and the skirt 12 while providing a constrained connection between the safety element 5 and the skirt 12. The hinge section 27 allows the safety element 5 to deflect towards the skirt 12.

[0118] Figure 18 A detailed view of the dividing line 30 and the first retaining bridge 31 of the closing device 3' is shown. Figure 19Shows a detailed view of the slit 23 of the closing device 3' and the second retaining bridge 22. The retaining bridges 31 and 22 are made of plastic and each has a certain cross-section so that they can be manually separated during the first opening.

[0119] Figures 20 to 26 Shows another embodiment of the closing device 3”. This closing device is highly similar to Figures 1 to 19 the closing devices 3 and 3' shown. Therefore, similar parts are labeled with the same reference numerals. Figures 1 to 19 The relevant description of Figures 20 to 26 also applies to

[0120] unless otherwise stated below. Figure 1 The closing device 3” can be used for

[0121] Figures 20 to 23 the container 2 shown. Figures 12 to 19 Shows that the closing device 3” has two dividing lines 30 (one on the front and one on the back, opposite each other) so as to divide the security element 5 into two security element segments 32. Each of these two security element segments 32 has a semi-circular configuration. Each security element segment 32 is connected to the skirt 12 via a hinge segment 27. In addition, a retaining mechanism 6 is provided, and its structure is the same as that of

[0122] Figures 24 to 26 the closing device 3' shown. Each security element segment 32 is connected to the skirt 12 of the base 10 via a second retaining bridge 22. Each dividing line 30 is bridged by one of the first retaining bridges 31. Figures 28a to 28c Shows a view of the closing device 3''' configured as a screw-type closing device. The screw-type closing device 3''' has a thread 39 on its inner upper side. The closing device 3''' is suitable for a container with an external thread, such as a bottle. The closing device 3''' has a security element 5, and its design is the same as that of Figure 1 the embodiment described. The security element 5 in particular has a second locking surface 7, which is configured as a locking projection and can interact with a first locking surface constructed on the container. The closing device 3''' has ribs 40 on the outer side of the lid so that the closing device can be opened more easily by rotation.

[0123] As in the previous embodiment, the security element 5 is held in the shown first position by the retaining mechanism 6 that forms a predetermined breaking point. Different from Figure 3In the embodiment shown, the safety element 5 is not connected by a relatively narrow retaining bridge, but by a flat sheet which tears open when the closure device 3''' is opened for the first time. The sheet can in particular have a film-like configuration. Production is achieved by appropriately designing the injection mould. In the open state, as described in connection with Figure 7 and Figure 8 , the safety element 5 moves outwards about the hinge section 27.

[0124] Figures 29a to 29c Figure shows a further embodiment of the closure device 3'''. The closure device 3''' is constructed substantially analogously to the closure device 3 shown in Figure 3 , see above. Different from Figure 3 , as in the embodiment of Figures 28a to 28c , the individual safety elements 5 are formed by sheets which tear open when the closure device is opened for the first time. In the open state, as described in connection with Figure 7 and Figure 8 , the safety element 5 moves outwards about the hinge section 27.
