Description

Technical Field

[0001] The invention relates to a closure device for a container containing a pharmaceutical composition, comprising a closure plug, a metal cover for fixing the closure plug to the container, and a top cover made of plastic, wherein a wirelessly readable electrical storage unit is connected to the closure device for identifying the contents of the container. Background Art

[0002] The aforementioned type of closure cap is known, for example, from the document WO 2013 / 149844 A1 (US2015 / 0298414A1). In addition, it is described in the documents WO 2016 / 090073 A1 (US10 450 116 B2) and WO 2019 / 076430A1 (US2020 / 193262A1). Such a closure cap is particularly used to be attached to a container for containing a pharmaceutical composition, and is thus also placed on an ampoule, for example. The closure cap can be designed as a crimped cap, in particular when using a metal cap, in particular in the form of an aluminum cap, wherein the metal cap is used to hold a closure plug, preferably in the form of rubber, in the area of ​​the container opening. An upper cover is attached to the metal cap as a further component of the closure device, for example as a cover. This upper cover is removed, for example torn off, from the metal cap in order to fix the metal cap and for possible subsequent use of the container closed by the closure device.

[0003] The upper cover, in particular the upper cover consisting of plastics, can also relate to a tamper-evident closure for a metal cover, wherein, in this relation, the manufacture of such an upper cover is also known in an injection molding process. Thus, such an upper cover can also, for example, be made of polypropylene (PP) or polyethylene (PE).

[0004] It is also known to provide such closures with a wirelessly readable memory unit, in which, for example, information about the contents (composition of the container contents, active ingredient, manufacturer, etc.) and / or information about the filling date and / or expiration date of the ingredients stored in the container can be stored. Summary of the Invention

[0005] Based on the above-mentioned prior art, the technical problem to be solved by the present invention is to further improve the above-mentioned type of locking device in terms of anti-tampering safety.

[0006] According to a first concept of the invention, the technical problem is solved by a locking device, wherein it is provided that the storage unit is effectively connected both to the upper cover and to the locking plug, and this effective connection has a permanent effect on the storage unit when the upper cover is torn off.

[0007] Removing or tearing off the cover from the metal cover and the closing plug surrounded by it can reveal the first use of the container sealed by the closing device. This first use can be detected by the permanent effect on the storage unit when the cover is removed and, if necessary, recorded. This advantageously allows the first use status to be determined when the storage unit is read after the cover is removed. This first use status is preferably not altered by reinstalling the plastic cover. Instead, the lasting effect on the storage unit renders this first use status almost permanent, so that at any subsequent point in time it can be verified that the cover (at an earlier time) has been removed.

[0008] By tearing off the cover, a corresponding state can optionally be actively set or released by electronic pulses in a memory unit, in particular a possible memory chip, which can preferably be read wirelessly to determine the tamper protection status.

[0009] When the cover is torn off, this removal can also be recorded in or on the storage unit by a permanent marking, in particular by a mechanically initiated marking.

[0010] Such a (mechanical) marking can in particular be recognized directly by a user, if necessary, or indirectly when using a conventional reader for reading the information stored in the memory unit.

[0011] In a preferred embodiment, at least that part of the memory unit which contains or stores the required information remains permanently on or in the closure device, at least for the usual period of use of the container.

[0012] Further features of the invention are described or illustrated below and in the description of the figures and in the drawings, but these features may also have inventive significance in combination with only one or more individual features described or illustrated here or may also have independent inventive significance independently or in other combinations.

[0013] Thus, according to a possible embodiment, a separating element can be provided, which exerts a permanent effect on the storage unit when the cover is removed. Alternatively, for example, the storage unit can also be partially fixed to the cover and partially fixed to the closing plug, thereby achieving a permanent effect on the storage unit when the cover is removed. In both cases, the storage unit is effectively connected to both the closing plug and the cover, either directly or indirectly (via the separating element).

[0014] When the stored information in a storage unit that is affected by removing the cover is read, it can convey information that is permanently generated by removing the cover. Accordingly, this information can be actively stored in the storage unit when the cover is removed, or generated during the reading process. In other embodiments, this information can only be generated when a suitable reading device is used, for example.

[0015] According to a possible embodiment, a permanent effect on the storage unit can be achieved by completely separating (tearing off) the storage unit, wherein the section of the storage unit containing the important and readable information preferably remains on the closing plug and thus on the container. Alternatively, the storage unit and the associated antenna, or only the storage unit or only the antenna, can also be removed. In this embodiment, the section of the storage unit that is completely torn off, if necessary, can provide an optical signal to the user. In addition, such a missing section of the storage unit can also be recorded when the information stored in the storage unit is wirelessly read. Thus, for example, such a missing or damaged section can also affect data transmission, resulting in data transmission being impossible.

[0016] This permanent effect on the storage cell can also be achieved by cutting or tearing the storage cell. Here, sections of the storage cell are not completely removed. However, just like complete separation, this cutting is irreversible and can therefore also be detected optically. Furthermore, this cutting or tearing can also permanently record the removal of the cover in the electronic path, which can also manifest itself, for example, through an effect on data transmission.

[0017] In a further embodiment, the storage unit can be an RFID (Radio Frequency Identification) tag or an NFC (Near Field Communication) tag or have such a tag. RFID and NFC are wireless or contactless communication technologies. Communication can take place between the storage unit and an electrically operated reader. Thus, such a system preferably consists of a reader and a transponder (tag), wherein a distinction is made between active tags and passive tags with respect to the tags. Active tags have their own power supply (battery), while passive tags do not have their own power supply but are powered by the electromagnetic field generated by the reader. Passive tags are preferably used in the present invention.

[0018] Another preferred embodiment uses high-frequency RFID (Radio Frequency Identification) tags or NFC (Near Field Communication) tags, for example, with a frequency of approximately 10 to 15 MHz, or even approximately 13.56 MHz. These transponders have a relatively short range, so that to read the stored data, the reader must be in the immediate vicinity of the transponder and, therefore, the closure and container. This involves a distance of several centimeters, for example, 2 to 5 cm or up to 10 cm.

[0019] A permanent effect on such a transponder when the cover is removed can be achieved, for example, by correspondingly affecting the antenna of the tag, for example by tearing off or tearing a part of the antenna, or by stretching or stretching the antenna as a whole or a part of the antenna.

[0020] The storage unit can be completely or fully bonded, preferably partially, to the cover and / or the closing plug. This bonding is preferably permanent and fixed, so that removing or tearing off the cover has a lasting effect on the storage unit. This bonding of the storage unit to the closing plug on the one hand and the cover on the other hand allows the storage unit to be torn or removed along a pre-defined tear line, in the same manner as if embedded in the corresponding material. When the storage unit is torn off, a section containing the important information preferably remains on the closing plug and, therefore, on the container, and, if necessary, another section of the storage unit remains on the removed cover.

[0021] The storage unit can also be partially or completely plastic-coated in its region associated with the cover, for example by the plastic forming the cover. This allows the relevant parts of the storage unit to be fixed to or in the cover during the production of the cover. Further sections of the storage unit can protrude in a flag-like manner and, after the plastic cover has been attached, can be bonded to, for example, a metal cover or directly to a closing plug to provide tamper protection.

[0022] In another preferred embodiment, the storage unit can be damaged by removing the cover. The storage unit is then preferably irreversibly marked, in particular completely or partially damaged, but in this case in an energy-damaging manner, so that the storage unit's functionality and / or the information content that may be stored are permanently affected after the cover is removed. This damage can, for example, directly or indirectly affect the RFID tag or NFC tag of the storage unit.

[0023] The destruction can be achieved by irreversibly separating two regions of the storage unit.It is also preferred that, during the destruction, a partial region of the storage unit is separated from the storage unit, for example in the form of a tear-off section.

[0024] The metal cover can have an opening which, in a preferred embodiment, can be larger than half the outer diameter of the metal cover up to at most eight-tenths or nine-tenths or more of the outer diameter. Here, the cover top provided around the opening can, for example, surround the closing plug in the form of a flange only at the edge.

[0025] The storage unit can also be loosely inserted between the metal cover and the closing plug. The storage unit, which is essentially attached to the closing plug, can be held in place simply by at least partially surrounding the storage unit with the metal cover. This can be advantageous in terms of manufacturing, but also in terms of the possibility of uniform cleaning.

[0026] Alternatively, the storage unit can also be completely or partially connected to the closing plug in a destructibly removable manner, for example by gluing or be completely or partially encapsulated by the material forming the closing plug.

[0027] In a possible design, the plastic-encased storage unit may have a predetermined tear line for separating portions of the storage unit. This predetermined tear line can be produced, for example, by limited thinning of the plastic material along a straight or curved line. Alternatively, the predetermined tear line can be produced by perforating the plastic material along a line, wherein the perforations along the line are preferably arranged uniformly and spaced apart, optionally in the form of slits, completely extending through the plastic material. The section of plastic material connecting the tear strip is preferably destroyed during removal of the cover, thereby enabling tearing along the predetermined tear line.

[0028] In this context, it can also be provided that, for example, two tearing directions are formed along a predetermined tear line spaced apart from the predetermined tear line, which are simultaneously destroyed during the removal of the cover. This results in a section that can be separated from the storage unit between these predetermined tear lines and can subsequently be used as a free part to be lost if necessary.

[0029] As a result, the storage unit can be clamped from below by the protruding section of the upper cover in the area separated by the predetermined tear line. By means of this protruding section, the area of ​​the storage unit separated by the predetermined tear line or the area bounded by two predetermined tear lines is mechanically acted upon during the removal of the upper cover, thereby causing damage due to separation along the predetermined tear line.

[0030] According to a preferred design, the predetermined tear line can extend through a section of the storage unit's antenna. The antenna, as part of the storage unit, can be connected to, for example, an RFID tag or an NFC tag. By appropriately destroying the antenna along the predetermined tear line, the antenna can be completely separated from the tag, for example. Alternatively, the destruction can result in a suitable reduction in the length of the antenna, rendering the storage unit inoperable.

[0031] Such separation of the antennas allows the antennas to be shortened, thereby reducing the power, for example, to 60% or less of the original value without the length or power being affected by the damage, or to 50% or 40% or less, or even to 5% or less.

[0032] By suitably reducing the power, for example, the data stored in the tag can no longer be read by a reading unit close to the locking device at a normal distance. The power reduction of the antenna can be achieved by suitably arranging the predetermined tear line to such an extent that the tag cannot be read contactlessly.

[0033] Furthermore, a wire can be provided as a separating element for separating (tearing off) the storage unit, said wire creating a connection between the cover and the storage unit. This connection can be achieved in the storage unit by having the wire firmly connected to the base of the storage unit and thereby ensuring the tearing off or separation of the storage unit when the cover is removed. Thus, a suitable separation of the storage unit can be implemented or achieved by tearing off the cover with the aid of the wire.

[0034] When such a wire is arranged, it can be fixedly connected to the cover, for example by appropriately gluing or encapsulating the end of the wire facing the cover with the plastic forming the cover.

[0035] Furthermore, such a separating element may also be in the form of a cutting element. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] A closure device 1 for a container 2 , for example an ampoule, containing a pharmaceutical composition (not shown) is shown and described.

[0058] For this purpose, the closure device 1 essentially comprises a closure plug 3, a metal cap 4 and a cover 5. In addition, a wirelessly readable storage unit 6 is preferably provided in the closure device 1, in particular for identifying the contents of the container 2.

[0059] The metal cover 4 can be formed and produced, for example, from a flat aluminum strip in a preferably combined stamping and forming process (deep drawing process). Furthermore, the aluminum strip preferably used for this purpose can consist of a laminate, for example, consisting of a metal film layer, which can be coated with a plastic layer on the top and bottom.

[0060] The metal cover 4 can have a cover top 7 and a cover top 7 in a normal use state, for example according to Figure 4 As shown in the cross-sectional view of FIG, the cover wall 8 is preferably extended downward. An opening 9 is preferably punched out in the center of the cover top 7, and the opening is formed in the state where the cover top 7 is finally mounted on the container 2. Figure 4 The illustrated portion can preferably be covered by a top cover 5 , which is dish-shaped here.

[0061] The locking device 1 is for example based on Figure 1 and 4 As shown, it is placed on the upper area of ​​the container 2. The elastic closing plug 3 is inserted into the mouth of the container 2, and is surrounded by the metal cap 4 on the upper side and the rim side. The metal cap 4 is also preferably bent (crimped) up to the undercut relative to the container mouth edge 10. In this regard, during the placement of the metal cap 4 on the container 2, the lower edge of the metal cap is pressed against the container 2, for example by a pressing tool. Figure 4 The undercut relative to the container mouth edge 10 is shown to facilitate contact with the container 2 .

[0062] A dish-shaped cover 5 is also mounted on the metal cover 4 for covering the opening 9 from above and preferably also for forming a tamper-proof lock. The cover 5 is preferably made of a hard metal material and is preferably manufactured in an injection molding process.

[0063] Specifically, the upper cover 5 may have an upper cover top 11 , which preferably extends over the entire upper surface of the metal cover 4 and also covers the cover top 7 of the metal cover.

[0064] A raised portion 12 may also be preferably formed on the lower side of the upper cover top 11, and the raised portion 12 preferably has a diameter that matches the opening 9 in the metal cover 4. The raised portion 12 also has a radially expanded portion 13 in the form of a flange on the end side, which acts as an anti-tamper safety device according to the embodiment of the present invention. Figure 1 、 4 In the covering position shown in Figures 5 and 8, 10, 12 to 14, the edge region of the opening 9 is clamped from below.

[0065] The plastic cover 5 can be removed by tearing it off from the metal cover 4. The radially expanded portion 13 is elastically displaced by the applied tensile force, thereby canceling the state of being clamped from below.

[0066] The metal cover 4 usually also has the aforementioned opening 9 on the upper side. The opening 9 is formed according to, for example Figure 4 The tamper-proof state shown in FIG is covered by the upper cover 5. After removing the upper cover 5, the opening 9 is exposed so that the locking plug 3 is pierced.

[0067] The storage unit 6 preferably provided in or on the locking device 1 is preferably an RFID tag or an NFC tag, respectively an electronic storage unit that can be read wirelessly. Figure 6 and 9 As shown schematically, such a memory unit 6, which is also referred to as a transponder, essentially comprises a memory chip 14 and an antenna 15. As also shown schematically, a plurality of antennas 15 can also be provided, in this case two antenna sections 24 and 25.

[0068] According to the embodiment shown, the storage unit 6 can be configured as a strip, as required. Figure 6 and 9 The top view shown extends longitudinally along a circular arc segment, but in this context, the storage unit 6 can also be, for example, annular in shape as a whole.

[0069] The storage unit 6 is arranged such that it is in a concealed position when covered by the cover 5, and a permanent effect is achieved by removing, in particular tearing off, the cover 5, in particular by tearing off, ripping, or stretching a partial section of the storage unit 6. This permanent effect on the storage unit 6 can be detected, in particular, when the storage unit 6 is read by a reader unit, so that during this reading process it can be determined whether the cover 5 is removed or has been removed (even if it is subsequently reattached to the metal cover 4). This provides information regarding whether the anti-tamper protection is functioning properly or whether the anti-tamper protection has been removed.

[0070] This permanent influence on the storage unit 6 is preferably irreversible.

[0071] Figures 1 to 7 A first embodiment is shown in which the storage unit 6 is fixed to the closing plug 3 by means of partial sections 16 and 17 on the upper side, facing the cover 7 of the metal cover 4. This fixing can preferably be achieved by means of an adhesive layer 19. The partial sections 16 and 17 can also preferably each be an end section of the storage unit 16. The middle section 18, viewed along the longitudinal extension of the storage unit 6, is preferably not connected to the closing plug 3, but to the upper cover 5.

[0072] In particular, for access to the storage unit 6, which is located essentially between the closing plug 3 and the metal cap 4, a through-hole 20 in the form of a window is preferably provided in the metal cap 4. The through-hole can extend completely across the width of the storage unit 6, which corresponds to a radial direction relative to the closing axis x in normal use. Preferably, the closing plug 3, the metal cap 4, the cover 5, and also preferably the container mouth edge 10 extend coaxially with respect to the closing axis. As viewed in the longitudinal direction, the through-hole 20 can optionally extend beyond the end-side partial sections 16 and 17 of the storage unit 6. In a preferred embodiment, the opening area provided by the through-hole 20 in the surface plane of the cap top 7 is selected to be between less than 40% and, for example, 20% or 15% of the entire annular metal cap surface.

[0073] In this embodiment, the through-hole 20 is preferably also used to handle the central area 18 of the storage unit 6 and to fix it to the underside of the upper cover 5 next to the cover 7. An adhesive layer 21 can also be provided for this purpose.

[0074] During the installation of the closure device 1, the intermediate section 18 can freely protrude beyond the surface of the metal cover 4 through its upwardly directed adhesive layer 21 after the closure plug 3 is fixed and the metal cover 4 is used on the container mouth edge 10 of the container 2, so that in order to fix the intermediate section 18, the cover top 7 is pressed against the adhesive layer 21 and adheres to it by the sealing lock of the upper cover 5 or the metal cover 4 connected thereto if necessary.

[0075] Recesses 22, 23 may be provided on the upper side of the closing plug 3 and on the lower side of the cover top 7 for accommodating the individual sections of the storage unit 6. Figure 5 ) shows the corresponding depth of such grooves 22, 23, which are usually in the unit range of one tenth of a millimeter, for example up to a maximum of 1 mm.

[0076] For example, Figure 6 , the memory chip 14 of the memory unit 6 is preferably arranged in the region of one of the partial sections 16 or 17, and an antenna section 24 is preferably also arranged together in the same partial section 17. The other partial section 17 has a second antenna section 25, which is connected to the memory chip 14 in the partial section 17 via the central section 18 of the memory unit 6. In this case, the antenna section 25 can also extend over the central section 18. Alternatively, only the connection line from the second antenna section 25 to the memory chip 14 can be provided in the region of the central section 18, if necessary.

[0077] like Figure 7As shown schematically, by tearing off the cover 5, a permanent effect is produced on the storage unit 6, so that according to the first embodiment, the middle section 18 is torn off due to the adhesion of the middle section to the underside of the cover 5 and the storage unit 6 is thus interrupted substantially transversely to its longitudinal extension. Figure 6 As schematically shown, the storage unit 6 can have predetermined tear lines 26 , which are pre-embossed, for example, on both sides of the middle section 18 .

[0078] The point-like or partially planar adhesive bonding between the storage unit 6, in particular the partial sections 16 and 17 and the closing plug 3, and the central section 18 and the cover 5, is selected in such a way that the bonding is ensured even when the cover 5 is removed. The central section 18 preferably remains adhered to the underside of the cover after the cover 5 has been removed. The storage unit 6 is permanently disconnected.

[0079] The partial section 17 of the memory unit 6 remaining on the closing plug 3 preferably also comprises a memory chip 14 with information stored therein, in particular about the contents of the container 2 , and a directly associated and electrically connected antenna section 24 .

[0080] Figure 8 and 9 An embodiment is shown in which the memory cell 6 has, for example, only two partial sections 16 and 17, which are connected only by a predetermined tear line 26. In this case, the predetermined tear line 26 also extends across the connection region between the memory chip 14 and the second antenna section 25.

[0081] Such a storage unit 6 can also preferably be connected to the closing plug 3 on the top side in the end areas of the partial sections 16 and 17 facing away from each other, for example glued, while the central area with the predetermined tear line 26 extends without adhesion to the closing plug 3.

[0082] The central, preferably non-adhesive region of the storage unit 6 can be accompanied by a separator 27 which is preferably permanently connected to the upper cover 5. Figures 8 to 11 In the embodiment shown in FIG. 1 , the separating element 27 is a wire 28, which is formed according to Figure 8 and 9The embodiment shown can be designed to be curved, for example, into an L-shape or LL-shape. The free first L-shaped base leg 30 of the wire 28, which is preferably curved accordingly, can be connected to the upper cover 5, for example by injection molding the free leg end during the manufacturing process of the upper cover 5. The L-shaped base connecting rod 29 connected to this L-shaped base leg 30 connects the storage unit 6 or a material area suitable for acting on the storage unit 6, preferably the material in the area of ​​the predetermined tear line 26, to the upper cover 5. In this case, a connection to the adhesive layer 19 supporting the storage unit 6 can be provided. However, the second L-shaped base leg 30 can also be encapsulated or embedded in the rubber material during the vulcanization process. The free second L-shaped base leg 30 is also preferably arranged to extend along the storage unit 6.

[0083] When the cover 5 is torn off, the wire 28 , in particular the L-shaped base link 29 of the wire, ensures that the storage unit 6 is preferably separated along the predetermined tear line 26 , so that the memory chip 24 is also separated from the second antenna section 25 in this embodiment.

[0084] According to further embodiments not shown in detail in the figures, the second and / or first L-shaped base leg 30 can also span a plane, for example due to a tooth-shaped staggered progression of the individual L-shaped base legs 30 .

[0085] In addition, the separator 27 may also be Figure 12 As an example, a cutting element 31 is shown, which can be fixed to the underside of the upper cover 5 via a connecting strip 32 and an adhesive layer 21. Such a cutting element 31 can also be integrally formed with the upper cover 5 and made of a uniform material. Here, tearing off the upper cover 5 can, if necessary, result in tearing the storage cell 6 (only) along the pre-defined tear line 26. However, according to the aforementioned embodiment, such tearing can, for example, separate the memory chip 14 from the second antenna segment 25. This allows for at least a lasting effect on the storage cell 6.

[0086] Figure 13 and 14 Another possible embodiment is shown in which the storage unit 6 is connected to the cover 5 at one end by overmolding, particularly in the region of the free end of the partial section 16, as viewed along its longitudinal extent. This allows the storage unit 6 to be permanently held at its end face in or on the cover 5, preferably during the production of the cover 5, in a plastic injection molding process. Another portion of the storage unit 6 (particularly the partial section 17, which is also preferably connected to the partial section 16 via a predetermined tear line 26 and includes the memory chip 14 and preferably the first antenna section 24) extends in a flag-like manner from the surface of the cover top 11 that faces the surface of the metal cover 4 in the installed position. For this purpose, the free end of the storage unit 6 or of the second partial section 17 facing away from the metal cover 4 can be provided with an adhesive layer 19, as shown, facing away from the metal cover 4.

[0087] During the (first) assembly process, the upper cover 5 can be fitted, for example, with the aid of a pressure plate 33 formed on the lower side of the upper cover 5 to act on the section of the storage unit 6 having the adhesive layer 19 on the lower side, so that the storage unit 6 can achieve the desired bonding to the surface of the metal cover 4.

[0088] In this embodiment, the storage unit 6 can also have a predetermined tear line 26 , in particular between the two partial sections 16 and 17 , along which a lasting effect can be achieved by separating the storage unit 6 when the cover 5 is torn off.

[0089] Figures 15 to 20 Another possible embodiment is shown. It can be seen that the top of the locking plug 3 in this configuration does not extend in a dome-shaped manner as in the previous embodiment, but extends substantially along a plane extending transversely to the locking axis x. As in the previous embodiment, a groove-shaped recess 34 can be preferably provided in the center through which the locking axis x passes. Figures 15 to 20 In the embodiment shown, the radially expanded portion 13 of the upper cover 5 may also extend into the recessed portion.

[0090] As a whole, the storage unit 6 can be designed in the form of a pie or disk, as shown, with a diameter that can be substantially equal to the outer diameter of the closing plug 3 .

[0091] In the center, which is penetrated by the geometric locking axis x, a hole-like opening 35 is provided in the storage unit 6, which, in the normal closed state of the locking device 1, is arranged according to Figure 15 The ridge 12 of the upper cover 5 is penetrated. At this time, the radial expansion portion adjacent to the ridge 12 clamps the edge section 36 of the storage unit 6 around the opening 35 below (see FIG. Figure 16 ).

[0092] The predetermined tear line 26, for example formed by perforation, extends coaxially with respect to the geometric center axis of the opening 35 and radially spaced from the opening edge in the support material of the storage unit 6, preferably made of plastic. Between this predetermined tear line 26 and the opening 35, an annular edge section 36 is produced.

[0093] The radial widening 13 of the upper cover 5 clamps the region of the edge region 36 at the bottom, and accordingly ends radially, preferably at a radial distance from the predetermined tear line 26 .

[0094] A memory chip 14 is held in the support material of the memory unit 6, for example by partial or complete plastic encapsulation. The memory chip 14 is electrically connected to an antenna 15, which can extend helically and approximately concentrically relative to the locking axis x (see Figure 17 ).

[0095] Extending outward from the helical line of the antenna 15 is a substantially radially extending antenna arm 37 which extends through the predetermined tear line 26 inwardly into the region of the radial section 36 (see Figure 17 ).

[0096] The storage unit 6 of this embodiment is fixed by overlapping the metal cap 4 placed on the closing plug 3. The storage unit 6 can accordingly be inserted between the metal cap 4 and the closing plug 3 in a substantially loose manner.

[0097] The opening 9 of the metal cover 4 has a diameter e, which can be approximately 0.8 to 0.95 times the outer diameter d of the metal cover 4. This creates a cover top 7 that surrounds the storage unit 6 in the form of an edge flange. The outer diameter of the helical antenna 15 can preferably be smaller than the diameter e of the opening 9 of the metal cover 4.

[0098] The upper cover 5 can be placed substantially flat on the flange-like edge of the hood top 7 .

[0099] By tearing off the upper cover 5, the radially extended portion 13, which serves as the separating element 27, is acted upon. The edge section 36, which is clamped below by the separating element 27, is torn off in an annular shape along the predetermined tear line 26, simultaneously separating from the antenna cantilever 37 that extends radially inwardly into the edge section 36. As a result, the antenna 15 is divided into two electrically separate antenna sections 24 and 25, of which at most only one antenna section can still be electrically connected to the memory chip 14.

[0100] The torn-off edge section 36 with the separated antenna extension 37 preferably remains on the raised portion 12 of the upper cover 5 .

[0101] The separation of antenna extension 37 and the resulting loss of functionality of antenna 15 result in a permanent effect on storage unit 6 overall.
