[0002] Label for sealing a container

[0003] The invention relates to a label for sealing a container, which clearly indicates the first opening of the container.

[0004] Labels are affixed to product packaging for identification purposes. For example, tamper-evident labels are applied to the openings of packaging or containers to indicate that the packaging or container is still intact, particularly unopened. They can also be applied to rotating or moving parts of a product to indicate, for example, that a valve is still closed. To open the packaging or container, or to move movable parts of the product relative to each other, the tamper-evident label must be cut. While cutting a tamper-evident label does create a cut in the label material, the cut edges are often shallow, making the damage to the label easy to overlook.If the intention is to deliberately conceal the fact that the packaging or container has already been opened, or that parts of a body have been moved against each other, a transparent film is often glued over the cut edge of the label, without it being immediately obvious that the original label has already been cut.

[0005] Therefore, there is a need to specify a label for sealing a container that provides clear proof of first opening and tamper protection.

[0006] A possible embodiment of a label for sealing a container, which can reliably indicate the first opening of the container and simultaneously provides protection against tampering, is specified in claim 1.

[0007] The label for sealing a container comprises a film with a die-cut line interrupted by material ribs within the film. The film has a first section and a second section. The first section is separated from the second section by the die-cut line and connected to the second section at the material ribs. The die-cut line runs through the film material in such a way that spaced-apart first sections are formed in the first section, and spaced-apart second sections are formed in the second section. The first and second sections are separated by the die-cut line and arranged alternately next to each other.

[0008] The top side of the label, which faces away from the container when the label is affixed to it, may be printed. The underside of the label may be adhesive, except for the areas containing the die-cut line or the first and second material sections. The underside of the label may, for example, be coated with an adhesive layer, with the adhesive layer being completely or partially omitted from the underside of the first and second material sections, or with an adhesive killer applied to the underside of the first and second material sections, either completely or with omitted areas. Optionally, the label may have back printing, for example, on the adhesive layer.

[0009] The label is affixed to a container in such a way that the first section of the film, except for the portion containing the first material segments, is adhered to the container body. The second section of the film, containing the second material segments, and the portion of the first section containing the first material segments, are positioned on a closure, such as a cap, of the container. When the container is opened by removing the closure from the container body, the fine material strips within the perforation line tear, separating the first and second material segments. The closure can be a primary closure that directly seals the container. Alternatively, the closure can be a secondary closure that completely or partially surrounds the primary closure.

[0010] The special geometry of the die-cutting line creates two spaced-apart sections of material in the first and second areas of the film. These sections are connected only at the material ribs and are arranged alternately side by side in the longitudinal direction, or dispensing direction, of the label. When the container is opened, perforated sections protrude from the container wall and the closure; these are formed by the first and second material sections.

[0011] When opening and / or resealing the container, the first and second sections of material protruding from the container body or the closure are difficult to return to their original position. After opening or resealing the container, the label exhibits a clearly visible deviation from its unopened state in the area of ​​the first and second material sections, making it readily apparent that the container has been previously opened. Furthermore, the shape of the perforated sections, and in particular the deformation of the first and second material sections after opening, makes tampering with the resealing process (recapping protection) difficult.

[0012] Creating the perforation in the form of a punched line interrupted by material ridges in the film material can be done simply, reliably (process-stable), and cost-effectively, without the need for complex steps such as heat application. The perforation, which provides tamper-evident protection, can be produced using all common methods, such as punching, cutting, or plotting the film material. Therefore, the proposed solution is inexpensive and easy to implement, as no additional components or production steps are required beyond the film material and a punching device, such as a plotter, laser cutter, or knife.

[0013] The label's manufacturability is independent of the die-cutting mechanism or other cutting mechanisms. The described perforation function can be achieved using mechanical die-cutting as well as laser die-cutting, particularly digital (thermal) laser die-cutting, or other mechanisms suitable for creating the perforation. The perforation can be externally marked by printing, for example, by printing a dashed line along the die-cut line onto the film. The perforation design can be directly produced using flexographic, screen, and digital printing. The label can be applied to a container using conventional equipment and is not subject to any process-related limitations regarding the container and its contents, such as those that exist with thermal processes.

[0014] This label is designed for multi-part containers with removable or individually movable components. It can be used to seal a rotating or movable part of a container. For example, the label can be used to seal a cap onto the body of the container. On containers with non-removable, individually movable components that activate a function, such as a valve, when rotated, the label can be affixed to the moving parts. This label is suitable, for example, as a tamper-evident seal for cap locks, syringe closure wraps (SCWs), pens, autoinjectors, and generally for pharmaceutical containers such as syringes, as well as containers for cosmeceuticals or non-medical products.

[0015] According to one possible embodiment of the label, the perforation line can be arranged in the film material in such a way that the first and second material sections interlock. This specific perforation design, after the separation of the first and second material sections by opening a container and the associated destruction of the label in the perforation area, causes the individual first and second material sections of the perforation structure to stand up, bend, and interlock with each other. As a result, the structure cannot self-assemble after the container is resealed, as it did before opening. Simply reassembling the container parts produces a clear visual effect indicating that the container has already been opened.The first and second material sections can interlock in a finger-like, hook-like, or wave-like shape. According to one possible embodiment of the label, the perforation line can be arranged in the film material such that the first and second material sections are finger- or hook-shaped. When the container is opened, the first and second material sections deform, making the initial opening of the container clearly visible. With this type of perforation design, the first and second material sections collide or interlock when an attempt is made to re-close the container.The finger- or hook-shaped first and second material sections thus bend and, after the first and second areas of the label are rejoined, no longer lie smoothly against the wall of the vessel body or the cap of the container, and therefore no longer in the same position as before the separation of the perforation.

[0016] Protruding and loose parts from the plane of the label are prevented by the material ridges that interrupt the die-cut line. Otherwise, the first and second material sections are separated from each other by the die-cut line, except for the few points where the material ridges are present. In the perforation design according to the invention, however, there is no die-cut on one side of the first material sections facing away from the second area of ​​the film, so that the film material is unweakened on this side. The first material sections are therefore connected to the remaining part of the first area of ​​the film. Likewise, there is no die-cut on one side of the second material sections facing away from the first area of ​​the film, so that the film material is unweakened on this side. The second material sections are connected to the material of the remaining second area of ​​the film on this unweakened side.

[0017] Since the first and second material sections are connected on one side to the material of the remaining first and second areas of the film, the formation of loose parts at the perforation points when opening a container is avoided if the material webs between the first and second sections are opened.

[0018] The label tears into sections of material. This prevents contamination of critical vessel parts, medical personnel, or open wounds by loose label fragments. The label can be single-layered. While a single-layer label can generally be applied to the body of the container, experience has shown that tamper-evident labeling, at least in multiple layers, is advantageous for tamper detection and security.

[0019] According to one possible embodiment, the label can comprise a first section containing the die-cut line and a second section positioned in front of the first section in the dispensing direction. The second section, which is applied first to the body of the container to be labeled during dispensing, can, depending on the container's size, form an inner label layer after application, which is covered by the first section. The first section, containing the die-cut line and the first and second material sections, thus forms an outer label layer.

[0020] According to one possible embodiment of the label, the second section of the film can have a second die-cut line that divides the second section of the film into a third and a fourth area. In the second section of the film, which runs ahead in the dispensing direction, the third and fourth areas are located on opposite sides of the second die-cut line.

[0021] According to one possible embodiment of the label, the second die-cutting line can run in the material of the second section of the film in such a way that at least a third material section is arranged in the third area of ​​the film, which is separated from the fourth area of ​​the film by the second die-cutting line.

[0022] The label can be applied to a container with a closure, such as a cap, in such a way that the second section of the label, forming the inner label layer, extends partially beyond the shoulder of the container body and onto the cap. When the container is opened by removing the cap, for example by twisting or pulling it off, at least one third section of the material is separated from the fourth section of the film. Similarly, the material webs in the first section of the label, forming the outer label layer, tear.

[0023] Since the first and second material sections are completely or partially free of adhesive on their underside, the first and second material sections of the first section of the label or the outer label layer form the perforation parts already described, which protrude from the body of the container and clearly and easily indicate the opening of the container.

[0024] The effect of the tamper-evident label can be enhanced by coating an area of ​​the second section of the film, or the inner label layer, which is positioned beneath the first and second sections of the outer label layer after the label has been dispensed, with a colored layer. This colored layer acts as a signal, becoming visible beneath the protruding sections after the container is opened and the first and second material sections are separated. In addition to or as an alternative to the colored layer, tactile elements, symbols, or lettering can be applied to this area of ​​the second section of the film or the inner label layer.

[0025] If at least one third section of the inner label layer, after dispensing, is free of adhesive on its underside, this third section will also protrude from the container body, resembling a flag, after the container is opened and separated from the fourth section of the film. When attempting to replace the cap, this third section, forming the flag, is folded by the outer label layer, preventing the protruding components of the label from properly aligning.

[0026] Since the second section of the film, which forms the inner layer after the label is dispensed, is in contact with the outer perforation, the second section of the label reinforces the deformation of the perforation structures of the outer label layer both when the container to which the label is affixed is opened and during resealing or joining of the separated

[0027] Material sections of the label.

[0028] One embodiment of a labeled container, for example a medical container, is specified in claim 15. The labeled container comprises a first sub-section and a second sub-section, wherein the second sub-section is displaceable relative to or removable from the first sub-section. Furthermore, the labeled container comprises a label for sealing the container according to one of the embodiments specified above. The first sub-section of the label is arranged at least partially on the first sub-section of the labeled container. The second sub-section of the label is arranged at least partially on the second sub-section of the labeled container.

[0029] The first section of the labeled container can, for example, be a vessel body for holding a substance. The second section of the labeled container can be a cap for closing an opening of the container. According to another possible embodiment, the second section can be a rotatable section relative to the first section of the labeled container, wherein rotating the first and second sections relative to each other triggers a function, for example, opening or closing a valve.

[0030] Depending on its length, the label can be applied once, less than once, or more than once around the circumference of the container. If the label has a second section in addition to the first, it can be applied more than once around the circumference of the container, provided it is long enough. In this case, the second section of the label, which runs ahead in the dispensing direction, forms an inner label layer. The trailing first section of the label forms an outer label layer, positioned over the second section and the inner label layer.If the second die-cut line in the second section of the label is offset from the first die-cut line of the first section, the inner perforation formed by the second die-cut line will be projected with a lateral or vertical offset relative to the outer perforation formed by the first die-cut line. If the second die-cut line is at the same height as the first die-cut line in the film material, the outer and inner perforations will remain at the same height in projection even after the label has been dispensed.

[0051] Figure 17 shows a design form of a griddled recess within an adhesive neutralization layer.

[0052] Figures 1A, 2A, 3, 6 to 9, 11, 12 and 15 show various embodiments of a label 1 for sealing a container, for example, a syringe closed with a cap, wherein the label has tamper protection and reliably indicates when the container has been opened, for example, when the cap has first been removed from a syringe body. The label 1 comprises a film 10 in which a die-cut line 11 runs, interrupted by material ribs 12 of a material of the film 10. The film 10 has a region 110 and a region 120, which are located on opposite sides of the die-cut line 11. Region 110 of the film 10 is separated from region 120 by the die-cut line 11 and is connected to region 120 only at the material ribs 12.

[0053] To apply the label to a container, for example a syringe, an adhesive coating can be arranged on the underside of the film 10. If the label 1 is affixed to a container, for example a syringe, such that area 110 is located on the body of the container, for example a syringe barrel, and area 120 is located on a closure of the container, for example a cap, the special type of perforation shown in Figures 1A, 2A, 3, 6 to 9 and 11 by means of the punch line 11 between areas 110 and 120 ensures that the initial opening of the container by removing the closure or cap is clearly and easily recognizable. Thus, the initial opening of the container is reliably indicated.

[0054] For this purpose, the die-cutting line 11 runs in the material of the film 10 such that spaced material sections 111 are formed in area 110 of the film 10 and spaced material sections 121 are formed in area 120 of the film 10. The material sections 111 and 121 are separated from each other by the die-cutting line 11 and are arranged alternately next to each other in the longitudinal or dispensing direction of the label.

[0055] Area 110 of film 10 has an adhesive underside, with the exception of the underside of material sections 111. Area 120 also has an adhesive underside, with the exception of the underside of material sections 121. Areas 110 and 120 may be coated with an adhesive layer on their underside, with those sub-areas on the underside of material sections 111 and 121 being either completely or at least partially free of adhesive or provided with an adhesive killer.

[0056] When the label 1 is affixed to a container as intended, such that area 110 adheres to the container body, material sections 111 extend beyond the container body onto the closure, and area 120 of the film 10 adheres to the container cap, the perforation structure is destroyed when the cap is removed, as the fine material webs 12 tear along the perforation line 11. Since material sections 111 and 121 are entirely or at least partially non-adhesive or adhesive-free on their underside, and thus have no adhesive coating, these perforated parts undergo significant deformation when the cap is opened and protrude from the container body or the cap, so that the label clearly indicates that the container has been opened.

[0057] When attempting to reseal the container by replacing the cap, the material sections 111 and 121 of the perforation no longer assemble as in the original state, but instead interfere with each other or shift amongst themselves or overlap, resulting in an arrangement of material sections 111 and 121 that differs from the original state and thus a state that differs from the unopened state, and therefore an optical effect or a different overall optical impression.

[0058] The effect is very pronounced due to the typical everyday combination of opening and resealing, whereby variations of the perforation structure shown are also possible, which cause deformation of material sections 111 and 121 only or primarily when the container is opened or resealed. The deformation of material sections 111 and 121 ultimately creates a striking overall appearance, which occurs both with regularly resealed containers and when attempts are made to manipulate the closure. Depending on the embodiment, the deformation occurs mainly during the separation or joining of the container parts, or in a combination of both processes.The special design of the perforation and the resulting deformation of the perforation parts or material sections 111 and 121 creates a striking overall optical image when the vessel parts, for example a syringe body and a cap, are simply brought close together. This provides a clearly recognizable indication of initial opening and makes it considerably more difficult to manipulate the joining of the material sections 111 and 121 back to their original state before the vessel parts were separated.

[0059] As shown in the embodiments in Figures 1A, 2A, 3, 6 to 9, 11, 12 and 15, the die-cutting line 11 can be arranged in the material of the film 10 such that the material sections 111 and the material sections 121 interlock. The material sections 111 lie between adjacent material sections 121 in the longitudinal or dispensing direction of the label, and the material sections 121 lie between adjacent material sections 111.

[0060] In the embodiment shown in Figure 1 A, the punching line 11 is arranged in the material of the film 10 such that the material sections 111 and the material sections 121 are wavy.

[0061] Figure 1B shows an enlarged section of area 110 of the film 10 of the label 1, depicted in dashed lines in Figure 1A, with a segment 20 of the die-cutting line 11. Segment 20 comprises sections 21 to 29. The die-cutting line 11 consists of several such segments 20. The individual segments 20 are separated from each other by a material web 12. Successive sections 21 to 29 can adjoin each other at an angle or be connected by a rounded edge. The individual sections of a segment 20 of the die-cutting line 11 are described in more detail below.

[0062] Segment 20 of the die-cutting line 11 has a section 21 which is arranged parallel to side 101 or the long side of the label 1 and perpendicular to side 102 or the short side of the label 1.

[0063] Following section 21, segment 20 of the die-cutting line 11 has a section 22 which is inclined with respect to sides 101 and 102 of the label and thus not parallel to sides 101 and 102 or to section 21. Section 22 of segment 20 of the die-cutting line 11 can, for example, be arranged at an angle between 40° and 50°, in particular at an angle of 45°, with respect to sides 101 and 102 of the label, or at an angle between 130° and 140°, in particular at an angle of 135°, with respect to section 21 of segment 20 of the die-cutting line.

[0064] Furthermore, segment 20 of the die-cutting line 11 has a section 23 following section 22, which runs parallel to side 101 and perpendicular to side 102 of the label. Section 23 is arranged parallel to section 21. Section 23 adjoins section 22 at an angle between 130° and 140°, in particular at an angle of 135°. Section 23 of the die-cutting line is interrupted by a material web 12.

[0065] Segment 20 of the die-cutting line 11 further comprises a section 24 following section 23, which runs obliquely to sides 101 and 102 of the label. The inclination of section 24 is opposite to the inclination of section 22. Section 24 of segment 20 of the die-cutting line 11 can, for example, be arranged obliquely or inclined at an angle between 40° and 50°, in particular at an angle of 45°, to sides 101 and 102 of the label, or obliquely or inclined at an angle between 130° and 140°, in particular at an angle of 135°, to section 23 of segment 20 of the die-cutting line.

[0066] Furthermore, segment 20 of the die-cutting line 11 has a section 25 that is arranged downstream of section 24. Section 25 can be curved. According to another possible embodiment, section 25 can be straight and connect to section 24 and a subsequent section 26 of segment 20 of the die-cutting line by means of a rounded edge. In this embodiment, section 25 can be arranged obliquely to sides 101 and 102 of the label. For example, section 25 of segment 20 of the die-cutting line 11 can be arranged obliquely or inclined to sides 101 and 102 of the label at an angle between 40° and 50°, in particular at an angle of 45°.

[0067] Section 26 of segment 20 of the die-cutting line runs obliquely to sides 101 and 102 of the label. Section 26 of the die-cutting line 11 can, for example, be arranged obliquely or inclined to sides 101 and 102 of the label at an angle between 40° and 50°, in particular at an angle of 45°. In particular, section 26 of the die-cutting line can run parallel to section 24 of the die-cutting line.

[0068] The segment 20 of the die-cutting line 11 further comprises a section 27 downstream of section 26. Section 27 can be curved, in particular curved in the opposite direction to section 25. According to another embodiment, section 27 can be straight and parallel to section 25. The straight section 27 can connect to section 26 and a subsequent section 28 of segment 20 of the die-cutting line by means of a rounded edge. In the straight embodiment, section 27 can be arranged obliquely to sides 101 and 102 of the label. For example, section 27 of segment 20 of the die-cutting line 11 can be arranged obliquely or inclined to sides 101 and 102 of the label at an angle between 40° and 50°, in particular at an angle of 45°.

[0069] Section 28 of segment 20 of the die-cutting line 11, which follows section 27, is arranged obliquely to sides 101 and 102 of the label. Section 28 of segment 20 of the die-cutting line 11 can, for example, be arranged obliquely or inclined to sides 101 and 102 of the label at an angle between 40° and 50°, particularly at an angle of 45°. In particular, section 28 of segment 20 of the die-cutting line can run parallel to sections 24 and 26.

[0070] Section 29 follows section 28 of segment 20 of the die-cutting line. Section 29 can be parallel to side 101 and perpendicular to side 102 of the label. Furthermore, section 29 can run parallel to and at the same level as section 21.

[0071] Figure 2A shows an embodiment of the label in which the die-cut line 11 is arranged in the material of the film 10 such that the material sections 111 and 121 are hook-shaped. In the embodiments of Figures 1A and 2A, the material sections 111 are separated from the area 120 of the film 10 by the die-cut line 11 and are connected to the area 120 of the film 10 only at the material webs 12. Similarly, the material sections 121 are separated from the area 110 of the film 10 by the die-cut line 11 and are connected to the area 110 of the film 10 only at the material webs 12.

[0072] Figure 2B shows an enlarged section of area 110 of film 10, depicted in dashed lines in Figure 2A, with segment 20 of the die-cutting line 11. Segment 20 comprises sections 21 to 27. The die-cutting line 11 consists of several such segments, each comprising sections 21 to 27. The segments are separated from each other by a material bridge 12. The individual sections 21 to 27 of segment 20 of the die-cutting line 11 are described in more detail below.

[0073] Segment 20 of the punching line 11 has a section 21 that is parallel to the side

[0074] 101 or the long side of label 1 and arranged at right angles to side 102 or the short side of the label.

[0075] Following section 21, segment 20 of the die-cutting line 11 has a section 22, which connects to section 21 via an arc of the die-cutting line. Section 22 of segment 20 of the die-cutting line runs almost perpendicular to section 21, or rather to side 101 of the label, and almost parallel to that side.

[0076] 102 of the label.

[0077] Furthermore, segment 20 of the die-cutting line 11 has a section 23 following section 22, which connects to section 22 via an arc of the die-cutting line 11. Section 23 of segment 20 of the die-cutting line is parallel to side 101 and perpendicular to side 102 of the label. Section 23 is parallel to section 21. Section 23 of the die-cutting line is interrupted by a material web 12.

[0078] Segment 20 of the die-cutting line 11 subsequently has an arc-shaped section 24 of the die-cutting line 11, followed by a straight section 25 of the die-cutting line. Section 25 runs parallel to side 101 of the label, or parallel to section 23 of segment 20 of the die-cutting line 11. A curved section 26 follows section 25 of segment 20 of the die-cutting line 11, curving in the opposite direction to section 24 of the die-cutting line. Following section 26, segment 20 has a section 27 that runs parallel to and at the same level as section 21.

[0079] In Figure 3, the finger-shaped material sections 111 and 121, formed by the special die-cutting process, are separated from each other by the die-cutting line 11 and connected only at the material webs 12. The material sections 111 are separated from the area 120 of the film 10 by the die-cutting line 11 and are connected to the material of area 120 of the film 10 only at the existing material webs 12. Similarly, the material sections 121 are separated from the area 110 of the film 10 by the die-cutting line 11 and are connected to the material of area 110 of the film 10 only at the existing material webs 12.

[0080] Figures IC and 2C illustrate the optical effect after opening and resealing a container 2, for example, a syringe, using the example of a wave-shaped perforation structure (Figure IC) or a hook-shaped perforation structure (Figure 2C) in the form of material sections / perforation parts 111 and 121. As a result of removing a closure or cap 4 from a vessel body 3 of the container, the material webs 12 tear. The material sections 111 then protrude from the vessel body 3. The material sections 121 protrude from the cap 4.

[0081] When attempting to replace the cap 4 on the vessel body 3 to reseal the container 2, the protruding material sections 111 and 121 interfere with each other by colliding, displacing, wedging, or interlocking, and by bending against one another, resulting in the striking overall appearance shown in Figures 1B and 2B. In particular, the material sections 111 and 121 no longer lie flat against the vessel body 3 or the cap 4 on their own, but protrude at least slightly from the vessel body or the cap, respectively. To conceal the manipulation, many parts would have to be laboriously repositioned simultaneously. These effects can be further intensified by using soft, stretchable, or contractile materials, or materials with internal tension, for the film 10.A stretchable or contracting material can be produced, for example, by printing inks and varnishes in the perforation area. These inks and varnishes preferably have shrinkage properties after drying and can thus contribute to the appearance of clearly defined, protruding perforation sections of the label after a container is opened. Internal tension can also be achieved by attaching special components or by targeted die-cutting, possibly in conjunction with a multi-layered film structure. Material sections 111 and 121, which exhibit internal tension, stretch and deform noticeably after the container is opened, thus making the initial opening of the container clearly recognizable.

[0082] Since material sections 111 and 121 remain connected to area 110 and area 120 of the film 10, respectively, after the material tabs 12 have been torn out on the unpunched connecting side, no loose label parts appear when the container 2 is opened. The position and orientation of the material tabs 12 can contribute to optimized tearing behavior of the perforation and significantly improve the prevention of loose parts after opening a container.

[0083] The position of the material ribs 12 along the punch line 11 is selected in such a way as to reduce the risk of the formation of undefined loose parts when the container 2 is opened, depending on the direction of rotation or torsion. This can be achieved by a targeted arrangement of the material ribs 12 in the perforation with respect to the opening direction of the removable component or cap 4 from the container body 3.

[0084] In the wave- or hook-shaped perforation contour shown in Figures 1A and 2A, the material webs 12 within the perforation are positioned and aligned such that they lie parallel to the expected initial force acting on the perforation. This minimizes the risk of loose parts forming at the perforation when the container 2 is opened, since the material webs 12 lie parallel to the initial opening movement and are not arranged at an angle to it. For example, the material webs 12 lie horizontally aligned on the horizontal sections of the perforation in the form of the perforation line 11 in the direction of rotation, which represents the initial load during opening by a pure rotational movement or a combined tensile / rotational movement, depending on the cap design. The finger-shaped design of the material sections 111 and 121 shown in Figure 3 is, for example, advantageously applicable to a threaded container.The material webs 12 are located here in the punching line 11 along the mechanically predetermined opening movement.

[0085] The die-cutting line 11 can be arranged in the material of the film 10 such that the material sections 111 and 121 each have the same or different lengths. For example, the material sections 111 and 121 can have a length between 1 mm and 5 mm, in particular a length of approximately 3 mm. The material sections 111 extend to the same extent or to different depths into the area 120 of the film 10. Likewise, the material sections 121 can extend to the same extent or to different depths into the area 110 of the film 10.

[0086] Figures 1A and 2A show, for example, embodiments of the die-cutting in which the material sections 111 and 121 have the same length and thus extend equally far into the area 110 and the area 120 of the foil 10 respectively.

[0087] Figure 3 shows an embodiment of the die-cutting in which the die-cutting line 11 is arranged in the material of the film 10 such that the material sections 111 and 121 have different lengths and thus extend to different extents into area 120 and area 110 of the film 10, respectively. Due to their different lengths, the material sections 111 and 121 are arranged in an alternating height arrangement in the material of the film 10 in the embodiment of the label shown in Figure 3.

[0088] Variations to the height arrangement of the material sections 111 and 121 shown in Figure 3 are possible. For example, alternating groups of material sections of the same length can be formed. For instance, alternating first groups of several adjacent material sections 111 and 121, respectively, having a first length, and second groups of several adjacent material sections 111 and 121, respectively, having a second length, can be provided. According to another possible embodiment, each material section 111 and 121 can have an individual length, or a random sequence of material sections 111 and 121 of different lengths can be provided.

[0089] In the finger-shaped configuration of the material sections 111 and 121 shown in Figure 3, it has proven advantageous if—as shown in Figure 3—the material webs 12 in adjacent material sections 111 and 121 are not at the same level. In those material sections 111 that extend deeper into the area 120 of the film 10, the material webs 12 are arranged above the material webs present in the shorter material sections 111.

[0090] Rotating the view so that the material sections 111, 121 are vertical, it can be seen that the material webs 12 along the section of the punching line 11, which limits the narrow, longer material sections 121 or which limits each first material section 121 of two depressions or each material section 121 to the right of a long material section 111, are at almost the same height, evaluated on the direction of the initial force, so that this element separates uniformly when the material webs tear.

[0091] Each subsequent material section 121, which lies before the next longer material section 111 or to the left of the longer material section 111, has a large open area in the transition to the remaining area 120 of the foil 10, which provides the necessary stability to avoid loose parts / undefined cracks, which is why the material webs do not have to be next to each other here (and cannot be due to the different heights that create the open area).

[0092] According to another possible embodiment of the die-cutting process, the die-cutting line 11 is arranged in the material of the film 10 such that the material sections 111 and 121 each have the same or different inclinations with respect to the longitudinal direction or dispensing direction of the label. The finger-shaped material sections 111 and 121 shown in Figure 3 can, for example, be uniformly inclined at a specific angle, such as 45°, in the longitudinal direction or dispensing direction of the label, or be alternately inclined or rotated individually or in groups in opposite directions.

[0093] In principle, the die-cutting using the die-cutting line 11 can be carried out in such a way that periodic die-cut structures are created from repeating shapes of the material sections 111 and 121 or a repeating sequence of the material sections 111 and 121. The die-cutting line 11 can also be arranged in the material of the film 10 in such a way that non-periodic die-cut geometries of the material sections 111 and 121 are formed.

[0094] The shape of the punching or punching line 11 can be optimized in such a way that, regardless of the opening movement of a container, as many perforation elements or material sections 111, 121 as possible are sufficiently deformed when the container is opened and, if necessary, when the container is resealed, in order to clearly show the initial opening or the subsequent resealing of the container.

[0095] Depending on the removal movement of a cap, for example, rotated, straight along the vessel body - without rotation, a combination of rotated and straight movement or successive different movements, the alignment of the material sections 111 and 121 can be achieved by a corresponding punching of the material of the film 10.

[0096] Figure 4 shows the execution of a die-cutting process using the die-cutting line 11, in which material sections 111 oriented alternately in different directions are formed at the edge of the area 110. In the illustrated configuration of the die-cutting line 11, stable material sections 111 are created that stand upright independently of the opening movement when a container on which the label is placed is opened, since the deformation of the material sections occurs reliably, at least in parts of the perforation, both during pure pulling movements and during twisting / pulling movements in both clockwise and counterclockwise directions.

[0097] Further variations of the perforation geometry can be created by asymmetrical punching, as shown, for example, in Figure 5. The punching shown in Figure 5 results in a sequence of asymmetrically shaped material sections 111. In addition to a clear initial opening indicator, statistically preferred opening movements can thus be taken into account.

[0098] The label 1 can be single-layered, with the underside of areas 110 and 120 being adhesive, with the exception of the underside of material sections 111 and 121, by applying an adhesive layer to the underside of areas 110 and 120, wherein the underside of material sections 111 and 121 is completely or at least partially excluded from the adhesive layer, or an adhesive killer is provided there, either completely or with cutouts. Optionally, a print 300 can be arranged on the top side of areas 110 and 120, or, in the case of reverse-side printing, also on the adhesive layer on the underside of the label, as shown on the top side in the example of the label embodiments in Figures 6-9.

[0099] The label can generally be arranged on a container such that a first sub-area of ​​material sections 111 and 121 is located on the container body and a second sub-area of ​​material sections 111 and 121 is located on the container closure, whereby the respective first sub-area and the respective second sub-area can have different proportions to each other. For example, the label can be affixed to a container such that the die-cut line 11 runs centrally to a contact line between the container body and the container closure, so that material sections 111 and 121 are arranged in equal proportions on the container body and the container closure.

[0100] The label can also be arranged on a container such that area 110, except for the part containing the material sections 111, is partially or completely wrapped around the circumference of the container body. The part of area 110 containing the material sections 111 and area 120 containing the material sections 121 can be partially or completely wrapped around the circumference of the container closure. Alternatively, the label can be arranged on a container such that area 110 containing the material sections 111 and the material sections 121 are located on the container body. The remaining area 120 of the film 10 is then located on the container closure.

[0101] As shown in Figures 1A, 2A, and 3, the label 1 can optionally have, in addition to a section 100 with the die-cut line 11, the material ribs 12, the areas 110 and 120, or the material sections 111 and 121, a section 200 extending ahead in the dispensing direction. Section 200 is shown with a dashed outline in Figures 1A, 2A, and 3. When the label 1 is placed on a container, the section 200 extending ahead in the dispensing direction forms an inner label layer on the container, depending on the container's circumference, upon which section 100 is placed as an outer label layer.

[0102] The label 1 is affixed to a container, for example, in such a way that the section 200 of film 10 forming the inner label layer extends over the shoulder of the container body, partially reaching the container cap. The inner label layer 200 can partially or completely encircle the container and be formed as a continuous strip or consist of several separate parts. For application to a container, the reverse side of section 200 of film 10 is coated with adhesive. The use of an adhesive killer in the area on the reverse side of section 200 that comes into contact with a removable container closure, such as a cap, may be advantageous. Potential benefits arise during application with regard to initial contact and force transmission to the individual parts of the container, and prevent the accumulation of dirt.

[0103] In the embodiments of the label shown in Figures 1A, 2A, and 3, section 200 of the film 10 has perforations 13, for example, I-shaped perforations. The inner label layer 200 with the perforations 13, when dispensed, can enhance the effect of the material sections 111 and 121 rising up after a cap is removed from a container. Similarly, the two-layered embodiment of the label, with the inner label layer 200 and the outer label layer 100, mechanically hinders the replacement of a cap after a container has been opened.

[0104] Figures 6 to 9 show further embodiments of the label 1 with tamper protection and function of the first opening indicator of a container, in which the label has, in addition to section 100, the section 200 extending in the direction of dispensing.

[0105] In the embodiment of the label 1 shown in Figure 6, a region 220 of section 200 of the film 10, which lies in an extension of material sections 111 and 121 at the level of material sections 111 and 121, is coated with a color 400. If the label can be wrapped around a container to be labeled more than once, for example, one and a half times or twice, the region 220 of section 200 coated with the signal color 400, which forms the inner layer, lies, when the label is dispensed, beneath material sections 111 and 121 of section 100 of the film 10, which forms the outer label layer. In addition to the coating with the color layer 400, lettering, symbols, or tactile elements can be arranged in region 220 of section 200 of the film 10.

[0106] After opening a container closure, the area 220 of section 200 of film 10, coated with signal color 400, becomes visible beneath the material sections 111 protruding from the container wall, forming a kind of flag. Additional letters or symbols can be placed on area 220 so that they are visible between the protruding perforation elements / material sections 111 when the container is open or resealed.

[0107] Figures 7 to 9 show embodiments of the label 1 with different perforation structures in section 100 of the film 10, wherein section 200 of the film 10 has a die-cut line 13. Section 200 of the film 10 is divided by the die-cut line 13 into a region 210 and a region 220, which are arranged on opposite sides of the die-cut line 13. The die-cut line 13 can be arranged in section 200 with or without interruptions in the form of material ridges 14 in the material of the film 10. The die-cut line 13 can run in the material of section 200 of the film 10 such that at least one material section 211 is formed in region 210 of section 200 of the film, which is separated from region 220 by the die-cut line 13. The material sections 211 may at most be connected to section 220 of the foil 10 via fine material bridges along the course of the punching line 13.The at least one material section 211 is connected to the remaining part of area 210 of section 200 of the film on a side facing away from area 220, where no perforation or material weakening is provided. The at least one material section 211 may be adhesive-free on its underside.

[0108] If the label shown in Figures 7 to 9 is affixed around the container to be labeled more than once in the manner described above, opening the container's cap will cause area 210 on the inner label section 200 to separate from area 220, and area 110 on the outer label section 100 to separate from area 120. In area 110 of the label, material sections 111 protrude from the container body, extending over the shoulder of the container body and having been positioned on the cap before the container was opened. In area 210, at least one material section 211, which is free of adhesive on its underside, also protrudes from the container body. This at least one material section 211 thus forms a flag projecting from the container body, on which lettering or symbols may optionally be arranged.

[0109] In this configuration as well, the inner label section 200, when dispensed, mechanically hinders the replacement of a cap after opening a container on which the label 1 is located. When attempting to replace the cap, the at least one material section 211, acting as a flag, is bent, thus preventing the cap from being replaced straight and / or hindering the seamless reassembly of label section 200 with label section 100 and, in particular, the protruding material sections 111 and 121. Since the inner label section 200 is in contact with the outer perforation, it exacerbates the deformation of the perforation structure both when opening a container and during resealing or reassembly of the individual label components.

[0110] Additionally, the appropriate length of at least one material section 211 serving as a flag prevents it from being pressed evenly under material sections 111 and 121. The protruding material sections 111 and 121 of the outer label layer 100 further hinder such manipulative action and thus reinforce the effect of the flag.

[0111] Section 200 of the film 10 can, in principle, have a single die-cut material section 211, which, acting as a flag, reinforces the indication that a container has been opened for the first time. Figures 7 to 9 show embodiments of the label 1 in which the die-cut line 13 runs in the material of section 200 of the film 10 such that several spaced-apart material sections 211 are formed along the upper edge of area 210 of the film 10. Each of the material sections 211 can, for example, be provided with symbols or lettering. The material sections 211 are separated from each other by the die-cut line 13, with a subsection 221 of area 220 of section 200 of the film 10 arranged between each of the material sections 211.

[0112] In the embodiments of the label shown in Figures 7 to 9, each of the material sections 211 thus forms a flag, which makes it difficult to reassemble the individual label components faithfully after separating the material sections 111 and 121. In particular, it is difficult to slide the material sections 211 back under the material sections 111 and 121 when reassembling the label parts without damaging the material sections.

[0113] In principle, section 200 can contain single or multiple different or repeating material sections / flags 211. Which and how many (different) material sections 211 are inserted depends on the objective, for example, increased deformation when opening a container or more difficult assembly of the individual label components when resealing the container.

[0114] Basically, the length of label 1 with the perforation contour is not limited, since the label, as described, can also be wrapped around a container several times, which can result in different distances between the perforation structures of the inner and outer label layers and different numbers of structures in the different label layers when projected onto the overlapping label layers.

[0115] According to one embodiment of the label, the die-cut line 13 in section 200 of the film 10 can be designed as an extension of the die-cut line 11, adjoining the die-cut line 11 without offset. The die-cut line 13 can have a shape similar to or identical to the die-cut line 11. For example, the die-cut line 13 in section 200 of the film 10 can run with the same orientation or inclination as the die-cut line 11 in section 100.

[0116] According to another embodiment of the label, the die-cut line 13 can have a different shape than the die-cut line 11. For example, the die-cut line 13 can run with an opposite orientation or inclination in section 200 of the foil 10.

[0117] Furthermore, embodiments are possible in which the die-cut line 13 in section 200 of the film 10 is offset from the die-cut line 11 in section 100 of the film 10. For example, the die-cut line 13 in section 200 of the film 10 can be arranged laterally, i.e., in the longitudinal direction or dispensing direction of the label, offset from the die-cut line 11 in section 100 of the film 10. According to another possible embodiment, the die-cut line 13 in section 100 of the film 10 can be arranged vertically offset from the die-cut line 11 in section 100.

[0118] Figures 10A and 10B show such embodiments of die-cutting geometries, in which a die-cutting line 13 with material ribs 14, similar to the die-cutting line 11 with material ribs 12, is introduced in the area 210 of section 200 of the film 10 shown in Figures 6 to 9. When the label is dispensed, the die-cutting lines 11 and 13 can be arranged overlapping and laterally offset from each other, as shown in Figure 10A. In the embodiment shown in Figure 10B, when the label is dispensed, an additional vertical offset occurs between the die-cutting lines 11 and 12 in projection due to the superimposed label layers.

[0119] The overlap of the die-cut lines 11 and 13, as shown in the dispensed state, can be achieved, among other things, by a label wrapped around a container more than once or multiple times, for example, one and a half or two times, or by a multi-layered label, for example, a two-layered label. The inner label layer, with the perforation structure introduced by the die-cut line 13, behaves similarly to the flag structures of the material sections 211 described above, in that it hinders the seamless reassembly of the individual label components and promotes deformation through fanning, bending, or entanglement of the individual material sections. In addition to the die-cut geometries shown in Figures 10A and 10B, the label layers lying on top of each other in the dispensed state can have die-cut geometries of different shapes and sizes.

[0120] Figure 11 shows a further embodiment of the label 1 with tamper protection and a function to indicate the initial opening of a container, wherein section 200 of the film 10 has a subsection 201 extending ahead in the dispensing direction and a subsection 202 following in the dispensing direction. Subsection 201 forms a leading label edge that widens towards subsection 202. In a dispensed state, the leading label edge 201 preferably only makes contact with the body of the container to be labeled, in order to avoid exerting pressure on a removable part, for example, a cap, and thus to simplify the dispensing of the label on dispensing machines.

[0121] It has been shown that opening a syringe labeled with the label shown in Figure 1A, as depicted in Figure IC, requires an opening torque of approximately 35.9 ± 3.7 Ncm to remove the cap from the syringe body. In contrast, opening the same syringe with a cap but no label requires only an opening torque of approximately 2.4 ± 0.6 Ncm. Therefore, attempts were made to modify, in particular, the geometry of the die-cut line to reduce the force required to open the cap.

[0122] Figure 12 shows a modified embodiment of the label 1, compared to Figure 1A and Figure 11, featuring tamper protection and an anti-recapping indicator. The die-cut between area 110 and area 120 has a modified shape compared to the die-cut line in Figure 1A and Figure 11. The label may optionally have a leading subsection 201 in the dispensing direction. Compared to Figure 11, the leading subsection 201 connects directly to area 110 of the label section 100. Furthermore, (security) perforations 13 may optionally be provided along the side (long side) 101 and / or along the side (cross side) 102 of the label.

[0123] Figure 13 shows an enlarged view of the die-cutting line 11 of the label in Figure 12. The die-cutting line 11 consists of several segments 20 with sections 21 to 25, each separated from the others by a material web 12. The individual sections 21 to 25 of segment 20 of the die-cutting line 11 are described in more detail below.

[0124] Segment 20 of the die-cutting line 11 has a curved section 21. The curved section 21 of segment 20 of the die-cutting line can, for example, be bent in a semicircle. A further curved section 22 of segment 20 of the die-cutting line adjoins section 21. Section 22 is semicircular and, in particular, bent in the opposite direction to section 21. Sections 21 and 22 merge seamlessly into one another, thus forming an S-shape of the die-cutting line 11.

[0125] Following section 22, segment 20 of punch line 11 has a section

[0126] Section 23, which is interrupted by a material web 12. Section 23 is straight and adjoins section 22 of segment 20 of the die-cutting line. As can be seen from Figure 12, section 23 can be arranged parallel to side 101 and perpendicular to side 102 of the label.

[0127] Segment 20 further comprises a section 24 immediately adjoining section 23. Section 24 can be arranged obliquely to sides 101 and 102 of the label or obliquely to section 23 of segment 20 of the die-cutting line. For example, section 24 of segment 20 of the die-cutting line can be arranged obliquely or inclined to sides 101 and 102 of the label at an angle between 40° and 50°, in particular at an angle of 45°, or obliquely or inclined to section 23 at an angle between 130° and 140°, in particular at an angle of 135°.

[0128] Section 24 is followed by section 25 of segment 20 of the die-cutting line. Section 25 runs straight and parallel to section 23, but is offset vertically along the transverse side 102 of the label relative to section 23 of segment 20 of die-cutting line 11.

[0129] Figure 14 illustrates the step-by-step modification of the perforation to create the die-cut line 11, starting from the geometry of the die-cut line 11 of the label in the embodiment shown in Figure 1A. The geometric perforation development can be described in four steps: First, the perforation of the die-cut line 11 shown in Figure 1A is straightened, then widened, then shortened, and finally mirrored. The perforation geometry of the die-cut line can be produced using standard methods, such as die-cutting, cutting, plotting, etc., of the film 10 material. No additional components or production steps are necessary.

[0130] In the embodiment shown in Figure 12, the underside of the material sections 111 and 121 is either adhesive-free or provided with an adhesive killer. Particularly when affixing labels 1, where the underside of the material sections 111 and 121 is completely adhesive-free, to containers with a small surface area, for example, 3 ml syringes, there is a risk that the material sections 111 and 121 will stand upright even before the containers are opened. This could give an end user the visual impression that the container has already been opened, even though it is still sealed in its original state.

[0131] Figure 15 shows a modified embodiment of the label of Figure 12, in which the unintentional erection of the material sections 111 and 121 is minimized when the label is affixed to a container with a small circumference. The label of Figure 15 corresponds to the design of the label of Figure 12, but—apart from the differently arranged (optional) perforations 13—unlike the label of Figure 12, it is not completely non-adhesive on the underside of the material sections 111 and 121.

[0132] Instead, the label 1 of Figure 15 has an adhesive layer 15 on the underside of the material sections 111 and 121, on which an adhesive neutralization layer 16 with recesses 17 is arranged. The adhesive neutralization layer 16 with the recesses 17 can be applied to the adhesive layer 15, for example, by a printing process. The adhesive layer 15 can correspond to the adhesive layer that is also arranged on the reverse side of the remaining areas 110 and 120 of the film 10. The material sections 111 and 121 are thus non-adhesive on their underside except for the recesses 17, so that the material sections 111 and 121 can adhere to a substrate at the recesses 17.

[0133] This largely prevents the material sections 111 and 121 from standing upright when the label 1 is applied to containers with a small circumference, for example, to the body of a 3 ml syringe. When the label is applied to containers with a larger circumference, for example, to a 5 ml syringe body, the effect of the material sections 111 and 121 standing upright is hardly noticeable, since the radius of curvature is different than, for example, that of the 3 ml syringe bodies. However, the embodiment of the label 1 with the adhesive neutralization geometry shown in Figure 15 is fundamentally suitable for all container sizes.

[0134] The embodiments of label 1 shown in Figures 12 and 15 exhibit significantly reduced opening forces for opening the syringe cap compared to the other embodiment of label 1A described above, when the label is affixed to a syringe as shown in Figure IC. For example, only an opening torque force in the range of 8.1 ± 0.4 Ncm is required to open the cap of the syringe labeled with the label of Figure 15.

[0135] The goal of reducing the opening force required to open a labeled container is achieved in the embodiments of the label shown in Figures 12 and 15 by making the S-perforation shape (S / 2 shape), which in the embodiments shown in Figures 12 and 15 is formed by sections 21 and 22 of the segments 20 of the die-cutting line 11, "shorter" than the S-perforation shape formed in the embodiment shown in Figure 1A by segment sections 24, 25, 26, 27 and 28, and by making the "diagonal lines of perforation," which in the embodiments of the label shown in Figures 12 and 15 are formed by sections 24 of the segments 20 of the die-cutting line 11, at a 90° angle to the diagonally inclined sections 22 of the segments 20 of the die-cutting line 11 in Figure 1A. It should be turned clockwise. This makes it easier to open a labeled syringe counterclockwise.

[0136] At the same time, in the embodiments of the label 1 shown in Figures 12 and 15, the formation of loose parts at the perforation when a container is opened is avoided. This is achieved, firstly, by the wider heights of the S-perforations (illustrated in Figure 13 by a double arrow) and, secondly, by the specific position of the material webs 12 on the horizontal sections 23 within the perforation geometry. In this way, the webs 12 are always oriented in the direction of rotation when the container is opened.

[0137] Figure 16 shows further embodiments of adhesive neutralization layers 16 with recesses 17, which, in addition to the embodiment shown in Figure 15, serve to minimize the unintentional erection of the material sections 111 and 121 when the label is applied to a small-circumference round body, and can be used for a wide variety of container sizes.

[0138] The cutouts 17, which form the adhesive areas of the film 10 within the adhesive neutralization layers 16, can have a wide variety of geometries (circle, rectangle, trapezoid, asymmetrical shape, etc.), different sizes (diameter, length, width, etc.), and be arranged at various positions relative to the perforation geometry. The cutout areas 17 are positioned within the perforation geometry at the critical points that would detach from the substrate in the event of complete adhesive neutralization. By selecting appropriately small cutout areas 17, the forces required to open a labeled container are not increased in a perceptible or significant way. The positioning, shape, and size of the cutouts 17 are designed so that process variations, such as pressure fluctuations, do not impair the functionality of the perforation.

[0139] In Figure 16, the recesses 17 in embodiments 1 and 5 to 10 within the adhesive neutralization layer 16 form completely recessed adhesive neutralization areas and thus sticky areas of the adhesive layer 15 of the film 10, which vary in their shape, size, number, and positioning relative to the perforation line 11. The embodiments shown represent only possibilities and are not to be understood as the only possible variants.

[0140] In embodiments 2 to 4, the recesses within the adhesive neutralization layer are each designed as a griddled adhesive neutralization area. Within the griddled adhesive neutralization area, the adhesive neutralization layer is arranged in a griddled pattern. Figure 17 shows, by way of example, a recess 17 with an adhesive neutralization layer 16 that is griddled to 60%, with spaced-apart points of the adhesive neutralization layer 16, between which the adhesive neutralization layer of the film is recessed, so that the adhesive layer 15 is present at these points.

[0141] In flexographic printing, by selecting "rasterized areas," regions within the printed label can be created that exhibit only partial stickiness. This allows for targeted, partial tackiness along the perforation contour in a specific area of ​​the label, ensuring the perforation adheres to the substrate and, simultaneously, that the perforation tears uniformly upon opening, preventing loose pieces and minimizing the opening force required. This effect can also be achieved in screen printing by selecting the appropriate screen opening. The various adhesive neutralization geometries can be produced using standard printing methods, eliminating the need for additional components or production steps.
