[0002] Labeling assembly for a multi-part vessel, system and method for applying a labeling assembly to a multi-part vessel

[0003] The present invention relates to a labeling arrangement that provides reliable identification for a container in a simple and cost-effective manner. The invention also relates to a system comprising such a labeling arrangement and a method for applying such an electronic labeling arrangement to a multi-part container.

[0004] Labeling arrangements typically include a label that can serve for authorization, authentication, or proof of origin. In particular, such labeling arrangements are used to provide information about a product's contents or for traceability, or when it is necessary to protect ingredients from unauthorized access. This applies, among other things, to containers in the pharmaceutical and medical sectors, whose contents need to be labeled and protected.

[0005] It is an object underlying the invention to contribute to a reliable and convenient labelling of a vessel in a simple and cost-effective manner.

[0006] The problem is solved by the respective features of the independent patent claims. Advantageous further developments are specified in the respective dependent patent claims.

[0007] According to one aspect of the invention, a labeling arrangement for a multi-part vessel comprises a sleeve-shaped cap element comprising a wall with an inner surface that establishes a first contact surface. The first contact surface is designed to be coupled, relative to a longitudinal axis of the vessel, by means of a press fit to an outer surface of a closure element of the vessel and to surround the closure element. The described labeling arrangement enables, among other things, reliable labeling of syringes. The cap element, as an adapter sleeve, provides a labeling surface so that a label can be reliably and stably applied to an upper and lower region of the vessel. The cap element can, for example, surround a narrow annular projection on an upper side or end face of the closure element, which is present in commercially available Luer-Lock closures.The cap element is essentially only applied to an upper region of the closure element, which is usually narrower than the structures located underneath, and is particularly designed in such a way that it does not protrude outwards or protrudes very little in comparison to the widest structures.

[0008] In this description, terms such as "top" and "bottom" as well as "inside" and "outside" refer to the correct arrangement or application of the labeling assembly and the container. This also applies to designations such as "head" and "body", where the head is generally arranged at the top and the body usually at the bottom. The closure element forms a primary closure of the container, for example an upper part of an injection vial or a syringe, and comprises, for example, in the style of a Luer-Lock syringe, a head part and a threaded part that can be screwed together. To open the container, the head part is unscrewed from the threaded part and removed. The container body forms a lower part of the injection vial or syringe and creates a container for holding and storing a predetermined content.

[0009] The cap element forms an adapter cap, particularly for narrow vessels, such as thin syringes, and is placed or pressed onto the closure element from above. The dimensions of the cap element are specifically tailored to the intended use on the closure element of the vessel, so that the first contact surface can be reliably pressed around the outside of the closure element. In this context, vessels or syringes are referred to as thin or narrow if the circumference of the closure element and the vessel body is approximately the same. This is typically the case with pharmaceutical or medical vessels, which have a relatively small diameter and are accordingly relatively narrow or thin.In other words, the described labeling arrangement is particularly suitable for containers whose top and bottom circumferential geometries are very similar and differ, for example, by only up to two millimeters in diameter. However, the labeling arrangement can also be beneficial for containers with different designs. Even small deviations in circumference can lead to adverse labeling performance and incorrect labeling, making fully automated labeling impossible, for example.

[0010] Using the described labeling arrangement, even with narrow vessels, such as a thin syringe with a Luer-Lock adapter or integrated Luer-Lock, a beneficial circumferential compensation can be created, thus contributing to improved labelability. For example, the vessel is realized as a plastic or COC syringe, in which the Luer-Lock closure is formed during injection molding. Alternatively, the vessel is realized, for example, as a glass syringe, to which a Luer adapter is clipped or pressed on. In an applied state in which the labeling arrangement is attached to the vessel, a label can be reliably applied and securely adhered both at the top in the area of ​​the vessel head and at the bottom in the area of ​​the vessel body. Using the described labeling arrangement, the label can be closed at the top and bottom with no or at least minimal wrinkling.An intermediate area, for example with a syringe shoulder and / or a threaded element, can thus be bridged, closed or sealed, in particular to counteract the undesired penetration of dirt, gas, steam and / or light.

[0011] The labeling arrangement can improve the RFID functionality of syringes or even enable RFID functionality, especially of thin syringes. The additional labeling surface created by the cap element allows the RFID transponder inlay or the antenna structure to be arranged higher up on the syringe and thus partially or completely relocated from the area of ​​the syringe body, which is normally filled with a liquid. This can have a particularly beneficial effect on the performance of the RFID functionality. Thus, reliable and convenient electronic labeling of a container can be realized in a simple and cost-effective manner, even on a very limited area of ​​the container, for example, a Luer-Lock syringe with a relatively small radius.In addition, the described labeling arrangement is also suitable for other primary packaging or containers in the pharmaceutical and / or medical sector, such as injection vials or vials.

[0012] According to a preferred development of the labeling arrangement, the cap element has an inner projection that establishes a second contact surface. The first and second contact surfaces are designed to coordinate with one another and with an annular projection on a top side or end face of the closure element, and provide a coupling structure in the form of a pinch groove or press groove that can be reliably coupled to the annular projection by means of a press fit. The first and / or second contact surfaces are preferably designed to be closed in a ring shape relative to the longitudinal axis, so that the press groove establishes a circumferential channel or trench into which the raised projection of the closure element can be pressed. The press groove is preferably somewhat narrower than the width of the end face projection, so that a reliable press fit of the cap element to the closure element can be established.

[0013] Furthermore, the first and / or second contact surface can be configured with a predetermined inclination relative to the longitudinal axis and can taper toward the other contact surface in the direction of an end face of the cap element. For example, both contact surfaces are configured to taper, so that the press groove tapers upwards on both sides. Alternatively, one or both contact surfaces are aligned parallel to the longitudinal axis and / or to each other. Furthermore, one or both contact surfaces can alternatively be configured to taper downwards, so that the press groove tapers downwards on one or both sides.

[0014] The cap element can be closed at its end face or, according to a further development, can have a penetrating opening, which is formed, for example, as a central recess on the end face. Such an opening can provide a channel for fluid exchange between an interior and an exterior of the cap element. This enables gas or liquid ingress and egress, which is useful, for example, during a sterilization process between an interior and an exterior of the cap element. This is advantageous, for example, in prefilled syringes that are sterilized with hydrogen peroxide, water vapor, or ethylene oxide (ETO) gas, so that the sterilization medium can pass through the recess in the cap element to the primary closure. Furthermore, such a fluid opening can be introduced, for example, in a side wall of the cap element and enable media exchange.In addition, a penetrating opening can ventilate the space between the closure element and the attached cap element, helping to prevent unwanted media entrapment in the space from adversely affecting the vessel and its contents. Furthermore, it can provide a means for pressure equalization in an otherwise hermetically sealed system.

[0015] According to a further development of the labeling arrangement, the cap element has a beveled guide surface on an underside of the wall, for example adjacent to the first contact surface, for placement on the closure element. The underside of the wall can accordingly have a bevel that is inclined upwards towards the longitudinal axis and enables simplified placement and guidance of the cap element. Furthermore, such a guide surface can be designed to match an outer contour of the closure element in order to establish a flush transition between the cap element and the closure element. In particular, commercially available Luer-Lock closures have gripping ribs that are rounded towards the top and become narrower. The guide surface of the cap element can be adapted accordingly and sit on the rounded, narrower area of ​​the gripping ribs and contribute to increased circumferential uniformity.Furthermore, an end position of the cap element on the closure element can also be specified.

[0016] If the cap element has an inner projection which, for example, fills the space within the annular projection of the closure element, the inner projection can also have a rounded portion on an underside, for example adjacent to the second contact surface, which can contribute to simplified placement on the closure element. According to a further development of the labeling arrangement, the cap element has a first contact surface and optionally also a second contact surface on both an upper side and an underside of the wall, which are separated from one another by an end wall. The cap element can accordingly be coupled to the outer surface of the closure element, with respect to the longitudinal axis of the container, both at the upper side and at the underside, by means of a press fit.The cap element can be used on both sides in this way, allowing for a simplified application process as it is no longer necessary to distinguish between top and bottom when aligning the cap element. The cap element can be inverted and thus have the same geometry of the first and / or second contact surface at the top and bottom. Alternatively, the cap element can have a different geometry at the top than at the bottom, for example with contact surfaces converging at the top, while the contact surfaces at the bottom are oriented parallel to one another, or only the first contact surface is present at the bottom. The end wall therefore forms a central dividing wall between the two attachment options for the cap element and, when pressed onto the closure element, nevertheless forms an end wall of such a system.

[0017] According to a further development of the labeling arrangement, the cap element has a web structure that is designed to match an outer contour of the closure element of the vessel and comprises a plurality of webs. The webs are designed to engage in corresponding spaces between gripping webs of the closure element. Such a closure element is typically present in Luer-Lock syringes, so that a larger and standardized labeling surface can be formed on the Luer-Lock syringe using the specially designed cap element.

[0018] Furthermore, one or more webs of the web structure can have a locking element in the form of a locking web or a locking projection, for example in the form of a locking hook. The locking web connects, for example, two or more webs to one another on an underside and forms a predetermined projecting edge on an inner side. A locking projection can be formed at a free end of a web and likewise form a predetermined raised edge towards the inside. The locking web and / or the locking projection are designed such that they can engage in a groove of the closure element of the vessel, so that a holding force in the direction of the longitudinal axis can be established between the cap element and the closure element with respect to the longitudinal axis.

[0019] Alternatively or additionally, the labeling arrangement can be further developed such that the cap element has a circumferential contour with respect to the longitudinal axis, which forms a negative shape to a circumferential contour of the closure element. By means of such an inverse shaping of the inner contour of the cap element, a particularly reliable hold on the closure element of the container can be established. The cap element forms a form-fitting cap, which realizes geometric compensation with regard to the closure element and can also be subsequently applied to existing syringes or other containers in order to provide them with improved labeling capabilities. In particular, a lower region of the cap element can be designed as a negative shape of a syringe cap orof the closure element so that adjustments to the support surface can be made and, in addition to simpler application, a maximally flush surface can be formed.

[0020] The cap element is particularly designed such that it extends only in the region of the closure element and only provides a short adapter cap on top of the closure element. Since the cap element is preferably intended for thin vessels, it has a correspondingly thin wall. The wall of the cap element can have a thickness of 0.5 to 1.5 millimeters based on a radial extension transverse to the longitudinal axis. Alternatively, the wall can also be designed with a thickness of only 0.3 or 0.4 millimeters. The wall of the cap element compensates for the diameter of the Luer-Lock closure, onto which the cap element is pressed, compared to the syringe body. Furthermore, the wall can also be designed with a wall thickness greater than 1.5 millimeters in order to compensate for differences in circumference. For example, the wall of the cap element can have a thickness of up to 3 millimeters.

[0021] According to a further development, the labeling arrangement comprises a label, wherein the label and the cap element are designed and coupled to one another in a coordinated manner, so that the label can be attached to the closure element of the container by means of the cap element. The label is designed, in particular, as an electronic label with an RFID functional unit, which has an RFID chip and an antenna structure coupled to the RFID chip.

[0022] The labeling arrangement can comprise an opening detection element arranged in a separation region of the label. For example, a perforation is provided so that, based on a state in which the labeling arrangement is attached to the vessel, opening of the vessel can be indicated by removing at least one partial element of the label from the vessel. The removable partial element can be designed as a label section and / or a conductor track section of the RFID functional unit and can indicate a visual and / or electronic opening. When the vessel is opened, the label is separated, for example, along a predetermined perforation and separated from the second partial element by pulling and / or twisting and is pulled or twisted upwards together with the primary closure or a part thereof and removed from the vessel body.A perforation acts as a cutting element and can, in particular, also be combined with punched-out sections or branches upwards and / or downwards, for example, to leave clearly visible damage after the label has been cut and the container opened. The perforation can, for example, be jagged-shaped to clearly indicate initial opening. Alternatively or additionally, the label can have a film or film element in the separation or cutting area that has a predetermined tear resistance.

[0023] The separation area of ​​the label is preferably attached to the container in such a way that it is assigned to a region that corresponds to a transition between the closure element and an adjacent element, for example a threaded element. The separation area can then also be referred to as a severing area, as it enables targeted severing of the connected label. Alternatively, the separation area is designed in a region tailored to the container, which, when the labeling arrangement is applied to the container, is assigned to a transition between a head part, for example a threaded element, and the adjacent container body. Thus, sufficiently strong turning and / or pulling on the additional element simultaneously leads to a predetermined separation of the labeling arrangement. However, the separation area can also be arranged in other areas.

[0024] By means of such a separation zone or an opening detection element, in addition to convenient labeling of the container, tamper protection can be implemented, which prevents, or at least clearly indicates, any opening of the container or any tampering with the closure element. Tampering or an attempted opening then leads to a clearly visible tearing of the label and / or destruction of a conductor track of the RFID tag. In the event of a severed conductor track, the RFID chip can thus detect an opening attempt in the form of a change in electrical conductivity and / or signal strength and provide an electronic opening detection element. Such an opening attempt can be stored in the RFID chip and read out as needed.Alternatively or additionally, the RFID functional unit can be configured in such a way that after the conductor track has been severed, it can either no longer be read or can only be read with a significantly reduced reading range, which clearly indicates that the device has been opened for the first time.

[0025] Preferably, an adhesive-free surface is formed in the cut-through area of ​​the label. This allows for easier separation of the label and removal of the respective upper sections. The force required to separate the closure element with the cap element and the label is reduced compared to fully bonded components, and the opening dynamics of the container applied with the labeling arrangement are improved.

[0026] The cap element is designed, for example, as a circumferentially closed sleeve with an end wall and can be slipped or pressed onto the closure element. Alternatively, the cap element can be slit on a side wall and / or form an upwardly open annular sleeve. The pressed-on cap element is at least partially in direct contact with the outer surface of the closure element, so that a reliable coupling in the form of a press fit is already established. The cap element is preferably designed to be rotationally symmetrical with respect to the longitudinal axis and can therefore be pressed onto the closure element independently of rotation. If a web structure with a locking element is provided, the cap element is pressed on until the locking element engages and establishes a holding force in the direction of the longitudinal axis.Alternatively or in addition to the web structure and / or in addition to the press fit, the cap element can be connected to the closure element by gluing and / or welding. When opening the container, only the holding force of the primary closure or the closure element on the container body needs to be overcome by twisting and / or pulling. Furthermore, the cap element can be designed to be deliberately extended upwards, allowing for an even larger labeling surface on the container.

[0027] The cap element is preferably formed from a plastic by injection molding and / or 3D printing. The cap element preferably comprises a plastic, such as polypropylene (PP), polyethylene terephthalate (PET), polycarbonate, cycloolefin polymers (COC), or cycloolefin copolymers (COP). The cap element can thus be manufactured cost-effectively and has a wall thickness of, for example, 0.5 millimeters or more on the circumferential side wall, which is sufficient for production and mechanical stability, without expanding the diameter of the closure element in the uppermost region beyond the diameter of the container body. Accordingly, the cap element, as an adapter cap, creates a surface in the uppermost region of the closure element that is sufficient for the adhesion of a label and has the same or similar circumference as the container body.Preferably, an outer surface of the cap element is pre-roughened and / or has a microstructure which contributes to a particularly reliable adhesion of the label.

[0028] For example, an outer surface of the cap element is designed to accommodate an RFID label equipped with a pressure-sensitive adhesive. This can be achieved by selecting a plastic with a high surface energy and / or surface roughness. The outer surface of the cap element can, for example, also have a ribbing, which, as a grip structure, enables a non-slip handling for performing an opening, rotating movement. The label can also provide a certain roughness or grip and contribute to an improved feel of the container provided with the labeling arrangement. Useful surface properties can be provided. The labeling arrangement preferably comprises an adhesive layer arranged on an underside. If an RFID functional unit is provided, this enables electronic readout of information.In conjunction with a functional carrier, such as a carrier film, the RFID functional unit can implement an RFID transponder or an RFID tag, which, as a flexible component, can form a so-called "soft tag." In conjunction with a component that is not significantly flexible, an RFID tag can implement a so-called "hard tag." Therefore, the label is particularly preferably implemented as an RFID label and has a carrier layer with an adhesive layer, so that the RFID label can be easily and reliably attached to the primary closure and / or the additional element by means of adhesive.

[0029] The RFID tag or the label can be single-layer or multi-layer. For example, it can be a wraparound or overwrap label that partially or completely encloses a circumference of the closure element and, for example, lies flat on itself. In terms of height or length, the label can partially or completely cover the closure element from bottom to top. Furthermore, the label can extend from a base end of the container body to a head end of the closure element.

[0030] The label can also comprise a reusable adhesive layer, by means of which the label can be attached to the cap element and at least partially removed again. The reusable adhesive layer is preferably based on a reusable adhesive layer, so that a label section can be adhered to the cap element, detached, and re-adhered. Alternatively or additionally, a reusable coupling between the label and the cap element can be established by means of electrostatic adhesion. Thus, for example, a label flag can be formed, which can provide particularly useful readability of the RFID functional unit. In particular, the antenna structure is then preferably arranged in the foldable and retractable label section for improved electronic readability.Alternatively or additionally, the RFID functional unit is designed as a multi-layer RFID label, for example, as a label booklet, and has at least one section that can be folded open and closed again, so that a label flag protruding from the remaining RFID label can be formed. According to a further aspect, the invention encompasses the use of an embodiment of the described labeling arrangement for a vessel that can be divided into several parts, comprising a vessel body and a closure element, which in particular form components of a relatively narrow Luer-Lock syringe.

[0031] According to a further aspect of the invention, a system comprises a vessel that can be divided into several parts and has a closure element and a vessel body that are coupled to one another. The system further comprises an embodiment of the previously described labeling arrangement, which is coupled to the closure element in such a way that the cap element is connected to the closure element by means of a press fit and the inner, first contact surface of the cap element contacts and surrounds an outer surface of the closure element. The vessel of the system is preferably implemented as a Luer-Lock syringe. The described labeling arrangement also enables, in particular, subsequent sealing or electronic labeling of prefilled syringes. The cap element provides a reliably labelable upper end of the system and can thus contribute to simple, automated, and process-reliable labeling, even of particularly thin vessels.Since the cap element is designed in such a way that it is pressed onto the narrow annular projection of the closure element and extends into existing gaps if necessary, a diameter of the closure element is not increased or is increased only very slightly.

[0032] Because the use and the system refer to or comprise an embodiment of the described labeling arrangement, the described properties and features of the labeling arrangement are also disclosed for the use and for the system and vice versa.

[0033] According to a further aspect of the invention, a method for applying an embodiment of the above-described labeling arrangement to a closure element for a multi-part container comprises providing the container with the closure element and the container body coupled to one another. The method further comprises providing the sleeve-shaped cap element and placing and pressing the cap element onto the closure element such that the first contact surface contacts an outer surface of the closure element and the cap element is secured to and surrounds the closure element by means of a press fit.

[0034] By means of the described application or assembly method, it is possible to use the properties and features provided by the labeling arrangement for secure protection and reliable and convenient electronic identification of the vessel. The method is accordingly also suitable for implementing an embodiment of the previously described system. Because the method relates to applying or assembling an embodiment of the described labeling arrangement and its arrangement on the vessel, the described properties and features of the labeling arrangement are also disclosed for the method, and vice versa. The coupling of the closure element to the vessel body can be carried out before or after the coupling of the cap element to the closure element. The method can further comprise providing and applying a label such that the label is attached to the cap element and to the vessel body.

[0035] It is a finding in connection with the present invention that the surface of closure structures, and in the case of glass syringes, the surface of a Luer-Lock closure, is poorly or unsuitably designed for the application of labels using pressure-sensitive adhesive. On the one hand, the surfaces are not sufficiently large and flat, and on the other hand, the materials used may have a surface microstructure and surface tension unsuitable for pressure-sensitive adhesive. For a variety of reasons, it is advantageous to label pharmaceutical syringes from the syringe body up to the primary closure. For example, this enables the following:

[0036] • Gain in labeling area for labeling and functionalities

[0037] • Implementation of an analogue seal and / or a digital seal with RF ID functionality

[0038] • Constructive solution to increase the performance of RFID functionalities

[0039] • Syringe sealing as part of light protection and / or gas barrier. Since closure elements or primary closures of commercially available syringes are generally unsuitable for label adhesion, for example, due to a flat surface that is too small or an external ridged structure, and are also usually not circumferentially consistent with the syringe or container body, the described labeling arrangement with the cap element enables a simple and reliable option for achieving a sufficiently large adhesive surface and circumferential uniformity for stable and long-lasting labeling. The cap element can be reliably attached to the designated closure element by means of a targeted press fit and requires no additional toothed structure on the inside or on the first contact surface.

[0040] The described labeling arrangement particularly takes into account the large number of vessels and syringe types available on the market in which the diameter of a syringe cap or closure is not significantly smaller than the diameter of the corresponding syringe body. For example, such thin vessels are realized as syringes with a Luer-Lock closure and a 1 ml filling volume, in which the closure element and the syringe body are almost identical in circumference. The cap element of the described labeling arrangement makes it possible to provide an adapter cap for such thin syringes in a simple and cost-effective manner, which surrounds the closure element without exceeding the diameter of the syringe body. Embodiments of the labeling arrangement thus enable, among other things, one or more of the following advantages:

[0041] • The cap element acts as an adapter cap and creates a sufficiently large adhesive surface, which is the same circumference as the injection body, for the stable adhesion of a label.

[0042] • The cap element, as a whole, or at least in the adhesive area intended for a label, is preferably not larger in circumference than the syringe body. If the cap element has components below the adhesive surface, such as the described web structure, this preferably also does not add bulk and utilizes existing free space on the closure element.

[0043] • The cap element has a sufficiently strong mechanical connection to the syringe cap for force transmission in both the rotational and axial directions. The labeling assembly utilizes structural features on the top side of the syringe cap or closure element to achieve a stable and reliable connection. Therefore, it is not necessary to directly glue the cap element or to design it to enclose the entire closure element for a secure fit.

[0044] Using the described labeling arrangements, reliable labeling of pharmaceutical containers can be achieved. These labels can be applied to such closure structures of prefillable syringes, preferably using pressure-sensitive adhesive, without having to modify the syringe's design and applicability. The described embodiments of the labeling arrangement enable both prior and subsequent application to a primary closure of a syringe, before or after it is or has been attached to the syringe body. Existing syringes can be retrofitted with RFID functionality in a simple and cost-effective manner using the labeling arrangement and the cap element.

[0045] An area between the cap element and the syringe body, which is smaller or equal in diameter to that of the syringe body, is spanned. Where the circumference is consistent with the closure element and / or the syringe body, the label is additionally bonded to a partial area. The cap element can also be adjusted in height or length along its longitudinal axis to accommodate the labeling requirements, for example, by being made extra long.

[0046] Particularly in designs with a crimp groove or press groove, the cap element enables reliable mechanical engagement with the top or distal side of the syringe cap or closure element. The crimp groove is specifically designed for commercially available closure elements, which are designed, for example, as hard plastic components and have an annular projection. This allows for a press fit on both sides of the projection, ensuring a secure and stable hold so that when the syringe is opened, the cap element is removed together with the syringe cap. The crimp groove of the cap element and the raised edge on the top side of the syringe cap, which engages with the crimp groove, are independent of rotational position. Accordingly, it is not necessary to consider any alignment with respect to the structural features of the closure element when fitting the cap element.To simplify the application of the cap element to or on the closure element, an inner side of the cap element can be designed in a lower, final area so that it is significantly wider or offers more internal clearance than in the upper area, which is firmly coupled to the syringe cap. A circumferential bevel can also be formed in the lower area, forming a type of chamfer so that the cap element can be attached with a larger tolerance. Such a specifically designed taper at the bottom of the wall automatically ensures that the correct end position is reached when the cap element is pressed on, and with appropriate pressure, a very strong connection is achieved through wedging. The cap element therefore has a self-adjusting design.

[0047] The flanks of the crimp groove, which are formed by the opposing first and second contact surfaces, can be parallel or inclined with respect to the syringe axis or the longitudinal axis. For example, both flanks are wedge-shaped and converge. Furthermore, it is possible for only one flank to run diagonally deviating from the syringe axis, while the other flank is aligned straight along the syringe axis. It is also conceivable for both flanks to run parallel in the axial direction. A press fit is then preferably achieved by making the groove gap of the crimp groove slightly thinner or narrower than the width of the annular edge on the syringe cap.

[0048] Even if the cap element with the syringe closure can primarily be implemented with rotationally independent structural features on the top of the syringe cap, it can also be beneficial to implement additional interlocking options. In this case, it can be useful to optionally utilize the spaces between the gripping ribs on the syringe cap using the described rib structure. Locking hooks or locking ribs can engage in a lower groove of the closure element, and despite such additional interlocking with lateral structural features of the syringe cap, the diameter of the syringe body is not exceeded by the specially designed cap element. Furthermore, the guide ribs of the standing structure, which preferably fill the spaces between the gripping ribs flush, can increase the available adhesive surface for a label.Individual webs of such a web structure can be connected to one another by means of locking webs or locking hooks. This can serve, for example, to stabilize the webs and hooks so that they do not break during placement and under the associated mechanical stress. In order to overcome the greater circumference in the area of ​​the gripping webs compared to the groove of the syringe cap, the locking hooks or locking webs are preferably not fully connected to one another. Provided defects or openings in the web structure allow escape to the outside in the area of ​​the gripping webs of the closure element when the cap element is placed on top. Once the individual locking hooks, the connected locking hooks or the locking webs have overcome the area of ​​the gripping webs of the syringe cap during placement, they engage in the groove of the syringe cap and provide additional interlocking.

[0049] In the following, exemplary embodiments of the invention are explained using schematic drawings. They show:

[0051] syringe and a labeling assembly attached to it,

[0056] Labeling arrangement, and

[0057] Figure 26 shows a flowchart for a method for applying the labeling assembly to a multi-part container. Elements of the same design and function are identified by the same reference numerals throughout the figures. For reasons of clarity, not all elements shown may be identified by corresponding reference numerals in all figures.

[0058] Figure 1 shows a schematic side view of a system 1 with a multi-part vessel and a labeling arrangement attached thereto. The vessel is designed as a Luer-Lock syringe 30 and comprises a primary closure with a closure element 31 and a Luer adapter or threaded element 32, which are coupled to a syringe body 33. For example, a content is arranged or can be arranged in the syringe body 33, which can be expelled from the syringe body 33 as needed by means of a syringe plunger 35. With reference to a longitudinal axis L, the closure element 31 can also be referred to as the head part or syringe cap of the Luer-Lock syringe 30. The closure element 31 and the threaded element 32 form a primary closure, forming a head-side end structure of the Luer-Lock syringe 30. The labeling arrangement, which comprises a sleeve-shaped cap element 10 and a label 20, is arranged on the closure element 31.The cap element 10 and / or the label 20 may comprise an RFID functional unit with an RFID chip 21 and an antenna structure coupled thereto (see Figures 23-25).

[0059] As described below with reference to Figures 1-26, the labeling arrangement enables reliable and convenient labeling of a vessel, which can particularly be implemented as a thin syringe, in a simple and cost-effective manner. The described embodiments of the labeling arrangement refer below to the Luer-Lock syringe 30 or, more generally, to a syringe 30, but are also applicable to other pharmaceutical multi-part vessels, such as injection bottles or vials.

[0060] Terms such as "top" and "bottom" as well as "inside" and "outside" refer to a proper arrangement or application of the labeling assembly according to the illustrated orientations of the syringe 30 shown in Figure 1. Therefore, the head of a particular syringe is usually arranged at the top, and the body is usually arranged at the bottom. The closure element 31 forms a component of the respective syringe 30 as a head portion, which is unscrewed and / or pulled off and removed from the syringe body 33 to open the syringe 30.

[0061] The cap element 10 is particularly intended to establish circumferential equality with the syringe body 33 at a head-side end of the syringe 30, thus contributing to improved labeling capability. The cap element 10 takes into account an upper structure of the closure element 31, which is generally narrower than a structure located underneath. The cap element 10 has a wall 13 with an inner surface that establishes a first contact surface 16 and is designed to be coupled to an outer surface 311, 312 of the closure element 31 by means of a press fit relative to the longitudinal axis L of the syringe 30 and to surround the closure element 31 (see also Figures 9 and 11-17).

[0062] Figure 2 illustrates, in a perspective view, how the cap element 10 is placed onto the closure element 31 of the syringe 30. Figure 3 shows, in a further view, the coupled state in which the cap element 10 is pressed onto the closure element 31. According to Figures 2 and 3, the cap element 10 has an outer surface or outer side 11 and an end wall or end face 12 and is designed as a sleeve that is open at the bottom and closed at the top. The outer side 11 forms an outer circumferential surface, and the first contact surface forms an inner circumferential surface of the wall 13 (see also Figure 6). The end face 12 is formed on an upper side 131 of the wall 13, opposite which a lower side 132 of the wall 13 lies (see also Figures 6 and 7).

[0063] The cap element 10 is pressed with its wall 13 around an annular projection 34 of the closure element 31, thereby establishing a circumferential equality or at least a circumferential similarity to the syringe body 33, so that the label 20 can be reliably attached to the top and bottom of the syringe 30. By means of the cap element 10, the label 20 can seal the syringe 30 at the top and bottom and bridge a transition area with the threaded element 32 as well as existing grip structures on the closure element 31. This reliably prevents dirt or other undesirable substances from entering the area of ​​the closure element 31 or the threaded element 32. The closure element 31 of the Luer-Lock syringe 30 typically comprises a grip structure with vertical gripping ribs 36 and intermediate spaces 37, as well as a horizontally circumferential groove 38 at the bottom (see Figure 2).The gripping webs 36 taper upwards toward the projection 34 and have a rounded portion 361. The cap element 10 is designed to utilize at least the narrower projection 34 or, if appropriate, also incorporate one or more of the previously described structural features of the closure element 31. A structure or surface finish on an outer side 311 or an end face 312 of the closure element 31 can also be incorporated.

[0064] Figure 4, for example, shows the design of the cap element 10 and the closure element 31 according to Figure 3 in a transparent configuration. In contrast, the cap element 10 in Figure 5 has a specially designed guide surface and / or support surface 15 on the underside 132 of the wall 13 (see also Figures 6, 8, and 10). The guide and / or support surface 15 enables simplified placement of the cap element 10. In addition, the rounded portions 361 of the gripping webs 36 of the closure element 31 are taken into account, and a transition between the cap element 10 and the gripping webs 36 is designed to be as flush as possible or to continue the contour.

[0065] Figure 6 illustrates, in a schematic view from below, a further exemplary embodiment of the cap element 10 with a central penetrating opening 121 through the end face 12. The cap element 10 can accordingly be realized, as in Figures 2, 8 and 10, as a closed or open adapter cap. Figure 7 shows, in a schematic view from above, a further exemplary embodiment of the cap element 10 with a central penetrating opening 121 through the end face 12, which is smaller than that in Figure 6. The cap element 10 according to Figure 7 can also be referred to as partially open. An opening in or through the cap element 10 can enable fluid exchange between an interior and an exterior of the cap element 10, which is useful, for example, during a sterilization process.Hydrogen peroxide, water vapor, or ethylene oxide (ETO) gas can pass through the opening 121 of the cap element 10 to the closure element 31 as a sterilizing medium. Figure 8 illustrates, in a schematic view from below, an embodiment of the cap element 10 that can be placed on one side of the closure element 31. In comparison, Figure 10 shows an embodiment of the cap element 10 that is extended along the longitudinal axis L, for example, to provide an enlarged adhesive surface for attaching the label 20. Alternatively, Figure 10 can also illustrate a cap element 10 that can be placed on both sides, as described below with reference to Figure 11.

[0066] Figure 9 shows a further embodiment of the cap element 10 in a schematic side view. The cap element 10 has an inner projection 18, which establishes a second contact surface 17. The second contact surface 17 is formed opposite the first contact surface 16 and delimits the inner projection 18 on a path with a smaller diameter than the circumferential first contact surface 16. The two contact surfaces 16 and 17 are designed to match one another and establish a squeeze groove or press groove 14, which is designed to match the annular projection 34 on the end face 312 of the closure element 31. The contact surfaces 16,

[0067] 17 allow a two-sided fixation of the cap element 10 to the projection 34 on the closure element 31. A width or a diameter of the inner projection

[0068] 18 radially to the longitudinal axis L is thus matched to a recess or a residue above the end face 312 of the closure element 31, which is circumferentially delimited by the projection 34. By pressing the annular projection 34 into the pinch groove 14 when the cap element 10 is placed on it, a bilateral press fit can be established and a particularly stable and reliable hold of the cap element 10 on the closure element 31 can be formed. The two contact surfaces 16, 17 are preferably annular or cylindrical in shape and are closed in themselves with respect to the longitudinal axis L, so that the pinch groove 14 is circumferential.

[0069] Furthermore, the first and / or the second contact surface 16, 17 can be designed with a predetermined inclination relative to the longitudinal axis L and, in particular, taper towards the other contact surface 16, 17 in the direction of the end face 12 of the cap element 10. Oblique flanks, which can be realized by inclined contact surfaces 16, 17, enable easier placement on the projection 34 of the closure element 31. In Figure 9, the first contact surface 16 is designed with an inclination, while the second contact surface 17 runs essentially parallel to the longitudinal axis L. In addition, the inner projection 18 adjacent to the second contact surface 17 has a rounded portion 181 which, analogous to the guide surface 15, enables simplified placement of the cap element 10 on the projection 34 of the closure element 31.Furthermore, the inner projection 18 can be matched with respect to a depth along the longitudinal axis L to the recess above the end face 312 of the closure element 31, which is circumferentially delimited by the projection 34. The inner projection 18 can be continuous, solid, or annular (see also Figures 15 and 16).

[0070] Figure 11 shows a transparent representation of another embodiment of the cap element 10, which can be used on both sides. The cap element 10 has a first contact surface 16 and a second contact surface 17 on both the top side 131 and the bottom side 132 of the wall 13, each of which forms a pinch groove 14. The embodiments are separated from one another by the end wall 12, which, according to this embodiment, establishes a central wall, but is arranged on the closure element 31 above the end wall 312 of the closure element 31. The cap element 10 can therefore be coupled to both the top side and the bottom side by means of a press fit with the projection 34 of the closure element 31.The fact that the cap element 10 can be used on both sides enables a simplified application process, since it is no longer necessary to distinguish between top and bottom when aligning the cap element 10. The cap element 10 can be of inverse design and thus have the same geometry of the contact surfaces 16, 17 at the top and bottom. Alternatively, the cap element 10 can have a different geometry at the top than at the bottom, as shown in Figure 11. In the embodiment on the top side, the first contact surface 16 is inclined and runs in the direction of the end wall 12 towards the second contact surface 17, which is aligned essentially parallel to the longitudinal axis L. On the underside, both contact surfaces 16 and 17 are aligned essentially parallel to the longitudinal axis L and oriented towards one another.

[0071] Figures 12 to 17 show further embodiments and / or views of the

[0072] Cap element 10. Figure 12, for example, shows a sectional view of the cap element 10 with converging contact surfaces 16 and 17, such that the pinch groove 14 becomes narrower towards the top. Figure 13 illustrates the cap element 10 according to Figure 12 in a transparent version. Figure 15 shows the cap element 10 according to Figure 7 in a perspective view from below. Compared to the version according to Figure 15, the cap element 10 according to Figure 16 has an extended inner flank or second contact surface 17. In this way, a particularly secure fixation can be established by a relatively long, bilateral pinch of the projection 34 on the closure element 31. Figure 17, for example, shows the cap element 10 according to Figures 7 and 15 in a transparent view and a perspective view from above.

[0073] Figures 18 to 22 show further possible embodiments of the cap element 10 with a web structure 19, which is designed in particular to match the existing structural features of the closure element 31. The web structure 19 comprises a plurality of guide webs 191, which are designed to engage in the spaces 37 between the grip webs 36 of the closure element 31. The guide webs 191 thus guide the placement of the cap element 10 when pressed onto the closure element 31 and can also contribute to a flush or balanced circumference on the closure element 31, which does not protrude outwards and provides an enlarged adhesive surface that can be reliably labeled (see Figures 19 and 21). The engaging guide webs 191 also provide an anti-twist lock around the longitudinal axis.

[0074] The web structure 19 according to Figures 18 and 19 has two locking webs 192, each forming a locking element on the underside of the cap element 10. The locking webs 192 connect a plurality of guide webs 191 to one another, in the present embodiment, four guide webs 191 each. Two free spaces or openings 193 are provided between the locking webs 192, so that no circumferential, self-contained locking web is present. This allows for beneficial elasticity of the web structure 19 to be established so that the cap element 10 can be guided over the gripping webs 36 of the closure element 31. In alternative embodiments, only one opening 193 or three or more openings 193 may be provided, each of which provides a range of movement for the web structure 19 outward (see also Figures 20-22).The guide webs 191 connected by the locking webs 192 are more stable than guide webs 191 that are not connected at their lower ends. The locking webs 192 have an inwardly raised locking edge or locking projection 194 (see also Figures 20 and 21) designed to engage the groove 38 of the closure element 31, so that a holding force can be established in the direction of the longitudinal axis L between the cap element 10 and the closure element 31. The locking edge thus protrudes inward compared to the adjacent sections of the guide webs 191.

[0075] Figures 20 and 21 show a further embodiment of the web structure 19 with a plurality of guide webs 191, at the lower end of each of which a locking element in the form of a locking edge or a locking projection 194 is formed. The respective locking projection 194 protrudes inward and is designed to engage the groove 38 of the closure element 31, so that a holding force in the direction of the longitudinal axis L can be established between the cap element 10 and the closure element 31 with respect to the longitudinal axis L.

[0076] Figure 22 shows a further embodiment of the web structure 19 with a plurality of guide webs 191, which are shortened compared to the longer guide webs 191 according to Figure 20 and each have guide surfaces 195 at their lower, free ends, which contribute to simplified insertion of the guide webs 191 into the spaces 37 and placement of the cap element 10 on the closure element 31. According to this embodiment, the beveled guide webs 191 have an arrow or cone shape.

[0077] Figures 23 to 25 show a further embodiment of the system 1 with the labeling arrangement, which comprises the cap element 10 and the label 20, which are attached to the syringe 30. The label 20 has an RFID functional unit and can accordingly also be referred to as an RFID label 20. The labeling arrangement preferably comprises an adhesive layer arranged on an underside of the RFID label 20. The RFID functional unit enables electronic storage and / or reading of information by means of the RFID chip 21 and the antenna structure. The RFID functional unit can be glued onto or to the cap element 10, for example, by applying a hard tag or soft tag, for example as a component of the RFID label 20. Alternatively, an RFID functional unit can already be integrated into the cap element 10 during its manufacture, for example by means of molding or so-called "in-mold" technologies.

[0078] The RFID label 20 is arranged on the syringe 30 such that it is attached to the pressed-on cap element 10 on one side and to the syringe body 33 on the other. As a wraparound or overwrap label, the RFID label 20 can close or seal the syringe 30 at the top and bottom and prevent the ingress of unwanted particles or unauthorized tampering. An intermediate area, such as the threaded element 32, is bridged and, for example, partially glued.

[0079] The cap element 10 is particularly designed and geometrically coordinated with the closure element 31 so that it does not lead to a widening of the syringe geometry. The widest point of the illustrated Luer-Lock syringe 30 according to Figures 1, 24, and 25 is defined, for example, by the gripping ribs 36 or a collar below the groove 38 in the transition to the Luer adapter 32. The cap element 10 is therefore adapted to the narrower point at the head end of the closure element 31, which has the projection 34.

[0080] The label 20 can further comprise or provide an opening detection element arranged in a separation region 23 of the label 20. The opening detection element comprises, for example, a perforation 24, which, as a cutting element, enables a controlled and predetermined cutting of the label 20 in the separation region 23. Thus, by removing a partial element of the label 20 from the syringe 30, the opening of the syringe applied with the labeling arrangement can be visually indicated. The removable partial element can be formed, for example, as a label section 25 and / or as a conductor track section 26 of a conductor track 22 of the RFID functional unit (see Figures 24 and 25). In the area of ​​the perforation 24, the label 20 may, for example, be non-sticky to facilitate the separation of the label 20 and the removal of a label section 25 and any conductor track 22 when opening the syringe 30.

[0081] The conductor track 22 alternatively or additionally provides an electronic opening detection element in the form of a device. The conductor track 22 is preferably placed over a separation line of the RFID label 20 and is formed, for example, by printing a conductive paste or as a component of the antenna structure of the RFID functional unit. The conductor track 22 can be connected to the RFID chip 21 of the RFID functional unit. When the syringe 30 is opened, the conductor track 22 is destroyed (see Figure 25), and conductor track sections 26 remain on the separated elements. Such destruction of the specifically arranged conductor track 22 can be registered by the RFID chip 21 as a detuning of the antenna structure or as a significant change in the reading range. Thus, as an alternative or in addition to mechanical versions of an opening indicator, an electronic first-opening indicator and tamper protection can be implemented using the labeling arrangement.

[0082] The cap element 10 can further be designed to deliberately increase the length of the syringe 30 (see Figure 10). This makes it possible, for example, for the RFID functional unit attached to the cap element 10 to be arranged closer to the bottom of a syringe barrel in which a plurality of syringes 30 can be accommodated upside down, and thus to be more reliably detected by reading devices intended to read the RFID chips 21 from the bottom of the syringe barrel.

[0083] The cap element 10 can further be formed with a predetermined surface structure on the outer surface 11, which is optimized or tailored for the application of the label 20. This can be achieved, for example, by a sufficiently large and suitably shaped flat surface of the cap element 10. The RFID functional unit can be applied as an RFID label 20 by means of pressure-sensitive adhesive to such a predetermined surface, wherein it is advantageous if a material of the cap element 10 has a surface tension suitable for the adhesion of a pressure-sensitive adhesive and / or if the outer surface 11 has a microstructure suitable for the adhesion of a pressure-sensitive adhesive.

[0084] A method for applying or attaching an embodiment of the labeling arrangement or for forming the system 1 can be carried out according to the flow chart in Figure 26 as follows:

[0085] In a step S1, the required components of the labeling arrangement as well as the elements of the syringe 30 to be coupled thereto are provided with predetermined and / or coordinated properties.

[0086] In a step S2, the cap element 10 is coupled to the closure element 31 by pressing, so that the first contact surface 16 contacts and surrounds the projection 34 on the outside. If the cap element 10 has the second contact surface 17 and the resulting crimp groove 14, the cap element 10 is pressed onto the annular projection 34 until it is pressed into the crimp groove 14 and is connected to the cap element 10 by means of a press fit on both sides.

[0087] According to step S1, the closure element 31 can be provided individually or already arranged on the syringe 30. If the closure element 31 has been provided individually, the syringe body 33 of the syringe 30 can be provided and coupled to the closure element 31 in a further step S3. The syringe body 33 can already be coupled to the threaded element 32 or can also be coupled to it in this step.

[0088] In a further step S4, the label 20, which comprises, for example, an RFID functional unit, is attached. The RFID label 20 is coupled or applied, in particular, adhesively, so that the RFID label 20 is adhered to the top of the cap element 10 and to the bottom of the syringe body 33. By means of the described labeling arrangement and the special cap element 10, structural features on the top side of the syringe cap or the closure element 31 are specifically utilized for mechanical fastening. This makes it possible for the cap element 10, as an adapter cap, to cover only the uppermost region of the syringe cap and to be firmly interlocked or pressed therewith. In commercially available syringes, the uppermost region is generally significantly thinner in diameter than the syringe body 33.It is a finding of the present invention that this narrow region for the cap element 10 can be used to create at least approximately a circumferential equivalence with the syringe body 33 at a head-side end of a thin syringe 30. Accordingly, the cap element 10 can be manufactured with a wall thickness sufficient for manufacturability and mechanical stability, yet still achieve circumferential equivalence in the applied region with the syringe body 33. The cap element 10 preferably offers sufficiently smooth surfaces for particularly reliable adhesion of the label 20, so that the label 20, which connects the cap element 10 to the syringe body 33, can be applied sufficiently firmly.

[0089] By means of the pressed-on cap element 10, a sufficiently strong coupling for force transmission in both the rotational and axial directions with the syringe cap or the closure element 31 can be implemented, so that when the syringe 30 is opened, the syringe cap can be removed together with the cap element 10. The designs of the cap element 10 particularly take into account structural features that are independent of the rotational position, such as the annular projection 34 on the top side of the syringe cap. The corresponding structural features of the cap element 10, such as the first contact surface 16 and / or the pinch groove 14, are also independent of the rotational position in this regard. As a result, the application of the cap element 10 can also be carried out independently of the rotational position, for example by simply and securely pressing it on from above without aligning the syringe 30 or the closure element 31, thus significantly simplifying the application process.In particular, a wedge-shaped crimp groove 14 facilitates the fitting process due to its self-adjusting design and results in particularly firm and stable wedging.
