Description

Technical Field

[0001] The invention relates to a seal according to the preamble of claim 1 . Background Art

[0002] The seal consists of a seal body and a sealing strip. To withstand extreme weather conditions, it is usually made of a weather-resistant material. Today, this is usually metal or plastic.

[0003] When applying the seal, the sealing strip is bent into a bay shape and in the process passes through two opposite openings in the elements that are to be separated from each other during opening or operation.

[0004] Described relative opening is for example the part of locking device.After forming bay like this, sealing band is fixed into ring by sealing body subsequently.

[0005] The term "loop" as used herein refers to a fixed eye in a rope and / or strap that will neither loosen nor tighten.

[0006] The ring is sized so that it cannot be removed without being irreversibly destroyed, for example to gain access to the container contents or the device, or to change settings.

[0007] By applying a seal, it is possible to prove that the settings have not been tampered with, that the container remains closed, or that the device has not been used.

[0008] Since the seal can only be removed by destruction, it will, at best, increase the amount of waste. At worst, it will spontaneously enter the environment. Both are detrimental to environmental protection.

[0009] DE 295 06 104 U1 discloses a seal made of cardboard material. The sealing body and sealing strip are integrally formed. The sealing strip extends from the sealing body. The sealing body consists of two foldable parts. These two parts are foldable about a fold running parallel or perpendicular to the direction of the sealing strip. Both parts are provided with an adhesive layer. In the operating state of the seal, the sealing body can be non-detachably sealed to the portion of the sealing strip distal thereto. During this process, the portion of the sealing strip distal to the sealing body passes through and adheres between the two parts of the sealing body.

[0010] CH 170 891A discloses an advertising seal. It consists of a seal body and an advertising label. The seal body connects to the sealing strip portion that enters and exits the seal body. The advertising label surrounds the seal body and covers the sealing strip portion that enters and exits the seal body. The advertising label can only be removed after the seal is released from the seal body.

[0011] WO 2020 / 157345 A1 discloses a safety tag comprising a safety belt. The safety belt has end pieces at its two distal ends that are non-detachably inserted into one another. The two end pieces are male and female. The safety belt is made of cellulose or a derivative thereof. The end pieces are made of biodegradable plastic.

[0012] US2004 / 032332 A1 discloses a cable tie-like seal made of a biodegradable material. The seal comprises a sealing body and a sealing strip with male and female fastening devices. The sealing strip is secured to the sealing body on one side. An information carrier can be integrated into the sealing strip or the sealing body. The information contained therein can be read contactlessly.

[0013] US Pat. No. 2,639,479 discloses an adhesive seal. The adhesive seal comprises a lower sheet, an upper sheet, and a safety strap. The lower sheet is provided with a through-hole for the end of the safety strap to pass through. The upper sheet is connected to the lower sheet by a hinge. The through-hole can be designed as a slit machined from the edge of the lower sheet or as a central hole. The free end of a strap (e.g., a wrapping strap or gift strap) is passed through the through-hole. By folding the upper sheet over the lower sheet, the portion of the strap located between the two sheets is secured by an adhesive layer provided on the side of the lower sheet facing toward the upper sheet. The adhesive seal, together with the strap, is secured to the package or gift by adhesion using the adhesive layer provided on the side of the lower sheet facing away from the upper sheet. Summary of the Invention

[0014] The object of the present invention is to provide a preferably environmentally friendly seal which is simple to operate and has improved tamper resistance.

[0015] This object is achieved by the features of the independent claims. Advantageous embodiments are reproduced in the claims, the drawings and the following description, including the content associated with the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. Additional advantages compared to the prior art, in addition to fully solving the proposed task, are also listed. The size ratios between the elements in the drawings do not always reflect the actual size ratios, because some shapes are simplified and others are enlarged for better illustration. For the same or equivalent elements in the present invention, the same reference numerals are used. In addition, for the sake of clarity, only the reference numerals required to describe the corresponding figure are shown in the figures. The embodiments shown are only examples of possible implementations of the present invention and are not exhaustive and limiting. The schematic diagram is shown below:

[0031] Figure 15- A perspective view of the seal 01 in its initial state, comprising a sealing strip 03 and a sealing body 02 (with a sealing core 05 and a sealing housing 06 accommodating the sealing core 05), which is designed to Figure 1-7 and Figure 8-14 The illustration shows two halves 61 , 62 of the sealing housing 06 , which are preferably integrally movably connected by a connecting piece 60 , for example with a fold line, and each half is composed of a portion 21 , 22 of the sealing body 02 .

[0032] Figure 16-Figure 15 A perspective view of the sealing core 05 of the seal 01 is shown, which is designed as a plate 55 and a security element connected to the plate along a fold line 51, which is arranged in the area within the circular mark 50 highlighted in the figure. The plate, including the security element connected to it along the fold line 51 (also called the fold line), has a semi-elliptical opening, which forms a projection on the security element (which serves as the locking element). The security element is provided with a hole. The plate is provided with a slit leading to the edge of the plate. To close the seal 01, the upper free end of a flexible locking element, for example, formed by a rope and referred to as a sealing strip 03, is inserted into the hole of the locking element, which is advantageous in minimizing the loop in the hole of the object to be sealed. In addition, the free end of the flexible locking element, formed by a rope and referred to as a sealing strip 03, is passed from below around the projection of the locking element and into the slit of the element, so that the rope is wrapped around the rigid projection and forms a loop.

DETAILED DESCRIPTION

[0036] exist Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The seal 01 shown in whole or in part comprises a sealing body 02 and a flexible locking element in the form of a sealing band 03 which can form a ring on the sealing body 02 and can be connected to the sealing body 02 in an irremovable manner (at least not non-destructively) in order to achieve sealing.

[0037] Seal 01 has an initial state and a working state.

[0038] The sealing body 02 comprises a sealing core 05 and a sealing housing 06 , which has two sealing housing halves 61 , 62 which are movably connected to one another along a connecting web 60 in the initial state.

[0039] For switching to the operating state, the sealing housing halves 61 , 62 can be non-detachably sealably connected at least to one another and advantageously to at least one, preferably two, mutually spaced-apart sections of the sealing strip 03 .

[0040] At least one of the sealing housing halves 61, 62 is provided with an adhesive layer for creating a seal with the remaining sealing housing halves 61, 62, formed by the non-detachable, sealable connection of the two sealing housing halves 61, 62. If necessary, this adhesive layer can also serve to secure one or more sections of the sealing strip 03 or at least contribute to this.

[0041] The adhesive layer can be protected by a special film in its initial state before the seal is applied.

[0042] In the initial state, one sealing shell half 61, 62 of the sealing body 02 is provided with a sealing core 05. In the operating state, the sealing core 05 is accommodated between the two sealing shell halves 61, 62 of the sealing body 02 which are non-detachably sealed and connected.

[0043] In the operating state, the sealing strip 03 is fixed along two mutually spaced sections between the sealing shell halves 61, 62 of the sealing body 02. In the operating state, the remaining portion of the sealing strip 03 extending outside the sealing body 02 and between the sections fixed on both sides is fixed in a loop.

[0044] Preferably, in the initial state, the first section of the sealing strip 03 is fixed on or in the sealing body 02. For example, the first section of the sealing strip 03 is at least partially fixed between the sealing core 05 and the sealing housing halves 61, 62 of the sealing body 02 provided with the sealing core.

[0045] The sealing core 05 has a securing element 50 for fixing at least a second section of the sealing strip 03 .

[0046] The safety element 50 of the sealing core 05 has an anchoring portion 53 which, in the initial state, is pivotably connected to the base portion 52 along a core fold line, referred to simply as fold line 51 and also as core fold line or core bending line. The fold line 51 can be formed, for example, by a fold.

[0047] Advantageously, in the operating state, at least the second section of the sealing tape 03 is wrapped around the anchoring portion 53 at least once.

[0048] Preferably, the section of the sealing strip 03 to be fixed for establishing the operating state is wound around the anchoring portion 53 at least partially parallel to the core fold line 51 .

[0049] The seal is characterized in that the anchoring portion 53 of the safety element 50 is surrounded on multiple sides by the remaining sealing core 55 of the sealing core 05 , but only part of this remaining sealing core 55 is connected to the anchoring portion 53 via a fold line 51 .

[0050] The remaining portion of the sealing core 05 defines a plane in which the anchor portion 53 adjoins the remaining portion of the sealing core 05 on multiple sides, or is even completely or partially surrounded by it. For example, the remaining sealing core 55 adjoins the anchor portion 53 on two or more sides. Advantageously, the remaining sealing core 55 can form a frame that completely or partially surrounds the anchor portion 53.

[0051] Preferably, in the initial state, at least the remaining sealing core 55 , preferably alternatively or additionally the base 51 , is connected to one sealing housing half 62 , preferably adhesively bonded.

[0052] Particularly preferably, the fold line 51 is realized by a half cut 43. The half cut 43 can be realized, for example, by either not completely cutting the cardboard, but only partially cutting it (especially with respect to its thickness or strength), or by gluing two cardboard sheets together, one of which is cut in the region of the half cut 43, while the remaining cardboard sheet extends continuously across the half cut 43.

[0053] Instead of a half-cut 43 , the fold line 51 can be realized, for example, by a perforation line or a fold, or by a combination thereof.

[0054] The anchoring portion 53 adjoins the fold line 51 on one side. The anchoring portion 53 is separated from the remaining sealing core 55 on its other side, for example by a separation line 56 produced by punching.

[0055] The separation line 56 preferably converges in a V-shape toward the fold line 51. This allows the sealing tape 03 to fit closely along the fold line 51 when it is at least partially wrapped around the anchor portion 53. The separation line 56 may span the fold line 51 on one side or on both sides, such as Figure 3 shown.

[0056] Adjacent to the fold line 51, a notch 54 may be provided. Preferably, such a notch 54 is provided along a portion around the anchor portion 53.

[0057] The fold line 51 can be formed by, for example, a fold.

[0058] The separation line 56 can be produced by punching. The notch 54 provided as needed can be produced by punching simultaneously with the separation line 56.

[0059] Advantageously, the anchoring portion 53 of the security element 50 is connected to the remaining sealing core 55 and therefore to the entire remaining portion of the sealing core 05 via the fold line 51. Preferably, there is no connection between the anchoring portion 53 and the remaining sealing core 55 on the side that may not abut the fold line 51. The separation line 56 extends along at least a portion of the separation portion.

[0060] The anchoring portion 53 is advantageously surrounded in a frame-like manner by the remaining sealing core 55 .

[0061] The anchoring portion 53 is preferably connected to the remaining sealing core 55 (preferably a frame) on one side by a fold line 51. On the remaining side, the connection between the anchoring portion 53 and the frame is interrupted (for example by punching). A notch 54 can interrupt the wrapping of the frame around the anchoring portion 53.

[0062] At least in the initial state, the remaining sealing core 55 (preferably a frame) is fixed, for example by an adhesive layer, to the sealing housing half 62. In contrast, in the initial state, the anchoring portion 53 can be pivoted outwardly about the fold line 51 from the plane spanned by the frame.

[0063] The sealing body 02 can be provided with a predetermined breaking point 04 which indicates by tearing an attempt to release the sealing strip 03 from the sealing body 02 , in particular from the safety element 50 .

[0064] The predetermined breaking point 04 can be realized by or include one or more perforation lines 41, 42 in the sealing housing 06. Preferably, such perforation lines 41, 42 extend from the ring toward the edge of the sealing body 02 and beyond the edge in the continuation of the direction of the section of the sealing tape 03 wound around the anchoring portion of the safety element 50 for establishing the operating state, for example at least through the sealing housing 06 to the middle of the sealing body 02.

[0065] Advantageously, the perforation lines 41, 42 are arranged on the two seal housing halves 61, 62 in a mirror-symmetrical manner with respect to the connecting piece 60. The fold line 51 can also be arranged (at least in the operating state) to overlap these perforation lines 41, 42. In this way, a continuous perforation, serving as the predetermined breaking point 04, extends along a line through all parts of the seal 01. Along this line, when the seal 01 is opened, the seal body 02, along with the seal core 05, is torn. This makes opening the seal 01 simple and requires little effort, while rendering it unusable for future use by destroying essential structural components.

[0066] It is particularly important to emphasize that the sealing core 05 is preferably provided with a groove 57 in the area of the base 52. The groove 57 preferably extends parallel to the fold line 51. The groove accommodates that portion of the sealing tape 03 section that was already connected to the sealing body 02 in the initial state. The section of the sealing tape 03 that was already connected to the sealing body 02 in the initial state is placed in the groove. The base 52 of the sealing core 05 faces the sealing shell half 62 with its side provided with the groove 57, and is bonded to the sealing shell half 62 through the sealing tape 03 section placed in the groove 57. In other words, the section of the sealing tape 03 that was already connected to the sealing body 02 and placed in the groove 57 in the initial state is bonded to the sealing shell half 62. Figure 2 When the right sealing housing half 62 is bonded to the sealing core 05 , it is directly sandwiched and bonded between the base 52 of the sealing core 05 and the sealing housing half 62 .

[0067] Here, the remaining sealing core 55 and the right sealing housing half 62 are also connected to each other by bonding. Only the anchoring portion 53 is connected to the sealing housing 06 at least initially only by the fold line 51 before the seal is switched to its working state.

[0068] To switch to the operating state, the sealing band 03 is wrapped around the anchoring portion 53 with a second section (which is spaced apart from the first section that was already fixed to the sealing body 02 in the initial state), preferably one and a half turns.

[0069] The second section of the sealing strip 03 can be fixed or realized on the sealing body 02 by the following steps:

[0070] - Folding the anchoring portion 53 outwards about the folding line 51 from the plane defined by the remaining sealing core 55 and the sealing housing half 62 provided with the sealing core 05 .

[0071] The section of sealing tape 03 to be fixed to the sealing core 05 for establishing the operating state is wound at least partially, preferably at least once, around the folded-out anchoring portion 53 . The winding is preferably carried out parallel to the fold line 51 .

[0072] - Folding back the anchoring portion 53 , which has been at least partially wrapped around by the sealing tape 03 section to be fixed, into the plane spanned by the remaining sealing core 55 and the sealing housing half 62 provided with the sealing core 05 .

[0073] The two sealing housing halves 61 , 62 are folded together around the connecting piece 60 and glued together.

[0074] The bonding is preferably achieved by peeling off the protective film from at least one of the sealing housing halves 61, 62. Subsequently, the two sealing housing halves 61, 62 are folded together around the connecting piece 60 so that their surfaces to be bonded to each other via the adhesive layer are aligned and placed one on top of the other, wherein the now unprotected adhesive layer on at least one of the sealing housing halves 61, 62 faces the other sealing housing half 62, 61.

[0075] The sealing strip 03 is wound directly onto the anchoring portion 53, preferably one and a half turns. This allows the sealing strip 03 to form a loop which securely holds the sealing strip 03 on the anchoring portion 53 when an attempt is made to pull the sealing strip 03 out of the sealing housing 06 after closing. This simplifies the manufacture of the seal 01 and its establishment in working order.

[0076] The sealing body 02 can be provided with at least one indicator for detecting at least one environmental influence.

[0077] Such an indicator can be integrated, for example, in a safety tag or security tag 07 .

[0078] The integrity of the container contents cannot be proven by conventional applied seals as long as the container contents can be altered without opening.

[0079] In other words, the integrity of the contents of a container to which the seal is applied cannot be proven by conventional seals, for example, as long as this integrity can be compromised only by environmental influences that do not require opening the container or direct contact with the container contents.

[0080] The same is true for sealed settings or sealed devices, which may be changed or damaged simply due to environmental influences.

[0081] In order to improve environmental compatibility, at least the sealing body 02 and / or the sealing strip 03 may be made of a biodegradable material.

[0082] Seal 01 can be used as follows.

[0083] In the initial state, the sealing housing 06 has two halves 61 , 62 (sealing housing halves) which are movably connected to one another via a connecting piece 60 .

[0084] In the initial state, the sealing core 05 is arranged on one of the halves 61, 62. Figure 2 In the embodiment shown, this is the right side half 62 .

[0085] Between the sealing core 05 and the corresponding half parts 61, 62 (at Figure 2In the embodiment shown, this is the right half 62 ), to which the first section of the sealing strip 03 can be fixed.

[0086] At least one of the halves 61, 62 may be provided with an adhesive layer which, after the two halves 61, 62 are folded together, non-detachably connects them to each other. This adhesive layer may be covered by a peelable protective film before use of the seal 01.

[0087] On at least one of these halves 61, 62 (at Figure 2 In the illustrated embodiment, the left half 61 is a portion where, for example, a self-adhesive security label 07 can be placed. In the initial state, the security label 07 protrudes laterally beyond the respective half 61, 62. The adhesive surface of the security label 07 that protrudes beyond the respective half 61, 62 can be protected by a label protector 08, for example, in the form of a tear-off film.

[0088] To create the seal, the anchoring portion 53 is first folded upward around the fold line 51 .

[0089] Next, the free end of the sealing tape 03 is passed through the eyelet or eyelet of the object to be sealed. Subsequently, the second section of the sealing tape 03 that has passed through the eyelet or eyelet is preferably passed through the notch 54 and wrapped at least once around the folded-up anchor portion 53. The anchor portion 53 is then folded back into the plane of the remaining sealing core 55 surrounding it.

[0090] The ring of sealing tape 03 created in this way and passed through the hole or eyelet of the object to be sealed is fixed by the following steps: First, the protective film that may be provided on the adhesive layer is peeled off. Then, the remaining sealing shell halves 61, 62 (in Figure 2 In the embodiment shown, the left half 61) is folded onto the sealing housing halves 62, 61 provided with the sealing core 05 (in the case of bending the connecting piece 60). Figure 2 In the embodiment shown, this is the right half 62 ).

[0091] The adhesive layer seals the two halves 61, 62 together and preferably also the remaining halves 61, 62 (at Figure 2 In the embodiment shown, the left half 61 is sealed to the sealing core 05 , while the second section of the sealing strip 03 is fixed in the sealing body 02 .

[0092] The label protector 08 can now be protruded from the security label 07 beyond the respective halves 61, 62 (at Figure 2 In the embodiment shown, the adhesive surface protruding from the left half 61 is peeled off.

[0093] The protruding portion of the security label 07 is then bonded to the other sealing housing half 62, 61 around the edge of the respective sealing housing half 61, 62 from which it protrudes.

[0094] It is important to emphasize that at least the sealing body 02 and / or the sealing strip 03 can be made of a biodegradable material.

[0095] In light of growing environmental awareness and demands, and to curb the harmful spontaneous release of plastics and metals commonly used in seals today, seals (01) employing seal bodies (02) and / or sealing strips (03) made of biodegradable materials aim to minimize their harmful environmental impact. This harmful environmental impact can result from both the spontaneous release of unwanted seals (01) and the regulated disposal of unwanted seals (01). It's important to note that spontaneous release is essentially impossible to completely prevent. However, the biodegradable design of the seal can mitigate the harmful effects of environmental release.

[0096] Biodegradable materials (BAW) must be broken down in large-scale composting facilities within 6-10 weeks. BAW are tested according to DIN standard EN 13432. They are not necessarily made from bio-based raw materials. Examples include so-called starch-based blends, such as corn starch blends, or certain polyesters.

[0097] The biodegradable material may be a biodegradable plastic.

[0098] For example, it is a biodegradable and bio-based plastic.

[0099] However, preferably, the biodegradable material is a naturally occurring, compostable material.

[0100] Particularly preferably, the biodegradable material is at least partially made of home-compostable material.

[0101] The possibility of home composting ensures that even those sealed 01s that are not industrially treated during disposal have the least possible harmful impact on the environment.

[0102] Composting, also known as composting or decaying, refers to the part of the nutrient cycle in which organic matter is broken down by soil organisms in the presence of atmospheric oxygen. In addition to carbon dioxide, this releases water-soluble minerals that act as fertilizers. Some of the intermediate products produced during this decomposition process are converted into humus.

[0103] The biodegradable material may be, for example:

[0104] biodegradable plastics, and / or

[0105] Biodegradable and bio-based plastics, and / or

[0106] Polylactic acid solid material, and / or

[0107] cellulose, and / or

[0108] cellulose esters, and / or

[0109] celluloid.

[0110] The biodegradable material may alternatively or additionally be based on the above-mentioned variants.Alternatively or additionally, the biodegradable material may comprise the above-mentioned variants.

[0111] Advantageously, in all described embodiments, the sealing body 02 , hereinafter also referred to simply as base body, can be made completely or partially of a water-resistant cellulose-based material.

[0112] Alternatively or additionally, the substrate or parts thereof may be made of waterproof paper or cardboard.

[0113] It is also important to emphasize that the term "sealing tape 03" encompasses a rope-like element with a maximum extent along its length. The rope-like element can have any geometric shape in its cross-section, which is transverse to the direction of its extension. The term "tape" in this context does not limit the cross-section to either a flat or circular geometry. For a flat geometry, the tape is best described as a strip. For a circular geometry, the tape is best described as a rope, cable, or wire. For seal 01, rope-like elements with the aforementioned cross-sectional geometries, as well as geometries intermediate therebetween, can be used. Sealing tape 03 can be designed to be flexible, elastic, pliable, or rigid without affecting the basic usability of seal 01. In this document, the term "sealing tape" refers to a flexible locking element with any cross-sectional shape. A flexible sealing tape preferably has a lengthwise extension that is significantly greater than its transverse extension. The term "sealing tape" is in no way limited to a specific cross-sectional shape. It can be flat, as is typical for tapes, but it can also be circular, as is common for ropes, cords, or wires. However, other shapes are also possible, such as an oval cross section, a hollow profile shape, or a flat symmetrical or asymmetrical cross section shape, for example similar to an asymmetrical or symmetrical aerodynamic profile, such as an airplane wing profile. In principle, any cross-sectional shape is suitable, provided that it has a low bending stiffness along the length of the sealing strip or even allows for a sealing strip that is flexible in bending, or alternatively or additionally allows for a sealing strip that is flexible in bending.

[0114] The seal 01 may alternatively or additionally have one or more features which are described in the introduction in conjunction with the prior art and / or in one or more documents relating to the prior art and / or in the preceding description of the embodiments shown in the figures.

[0115] For example, the seal 01 can be used to seal containers or devices, for example on their housings, as is known, for example, as a customs seal in international goods and freight traffic.

[0116] For example, by applying the seal 01 to the closure of a container or device (referred to as "applying the seal"), it is possible to determine whether the container or device has been opened without authorization after the seal has been applied. This also applies to other uses of the seal 01, such as as evidence that the settings on the device have not been changed, as a substitute for an entry ticket, for disabling a technical connection without disabling it, and for use in military facilities.

[0117] The invention is not limited to the description of the exemplary embodiments. Instead, the invention comprises any novel feature and any combination of features, in particular any combination of features in the claims, even if this feature or this combination itself is not explicitly mentioned in the claims or exemplary embodiments.

[0118] The invention has industrial applicability particularly in the field of manufacturing customs seals and similar items.

[0119] Furthermore, the invention has industrial applicability in the field of manufacturing and operating plants and devices in which unauthorized changes to settings or unauthorized access (for example by breaking of a seal) must be detectable afterwards.

[0120] The present invention has been described with reference to preferred embodiments. However, it will be appreciated by those skilled in the art that modifications or variations may be made to the present invention without departing from the scope of protection of the appended claims.
