Description

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

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

[0003] During the sealing process, the sealing strip is folded into a loop, forming a cove. The sealing strip is then passed through two opposing openings on elements that are separated from each other when opened or operated.

[0004] The opposing openings, for example, form part of a closure. Once the loop is formed, the sealing strip is then secured into a loop using the seal body. The loop is sized so that it must be irreversibly destroyed to be removed. The loop must be removed, for example, to gain access to the contents of a container or a device, or to change a setting.

[0005] In this document, the term "loop" refers to a fixed eye in a rope and / or strap. The fixed eye neither loosens nor tightens.

[0006] Because a seal can only be removed by destroying it, at best it contributes to the amount of waste. At worst, it is spontaneously released into the environment. Both are detrimental to environmental protection.

[0007] German patent DE 295 06 104 U1 discloses a seal made of cardboard. The seal body and sealing strip are a single piece. The sealing strip extends from the seal body. The seal body consists of two hinged parts. Both parts are coated with an adhesive layer. In its operational state, the seal body can be permanently sealed to a portion of the sealing strip spaced apart from it. The portion of the sealing strip furthest from the seal body is threaded between the two parts of the seal body and adhered to them.

[0008] A promotional seal is known from CH 170 891 A. It consists of a seal body and an advertising token. The seal body connects the incoming and outgoing parts of the seal band. The advertising token surrounds the seal body and covers the parts of the seal band entering and exiting it. The advertising token can only be removed after the seal has been detached from the seal body.

[0009] WO 2020 / 157345 A1 discloses a security label comprising a tamper-evident band. The tamper-evident band has interlocking end pieces at both distal ends. The end pieces are of the male and female type. The tamper-evident band is made of cellulose or a cellulose derivative. The end pieces are made of biodegradable plastic.

[0010] US Patent 6,098,253 discloses a one-piece fastener. This fastener is used to attach a ski pass to a skier's clothing. The fastener is made of a biodegradable material and has a band-like section with two male / female end pieces. To connect the two pieces, the male end piece is inserted through an opening in the female end piece.

[0011] US Patent 3,045,303 discloses a seal comprising a seal body and a seal band. The seal body can be made from renewable raw materials. Renewable raw materials include, for example, organic cellulose derivatives such as cellulose ethers and cellulose esters. The seal band can also be made from organic cellulose derivatives. These organic cellulose derivatives include, for example, plasticized cellulose acetate or cellulose acetate butyrate. The seal body can be detachably connected to at least two spaced-apart portions of the seal band. In an operational state, the seal body can be permanently sealed to the two spaced-apart portions of the seal band. The seal body can consist of at least two parts that can be permanently sealed to each other in an operational state.In an embodiment where both parts are made of metal or semi-rigid plastic, they can be connected to each other by a spring-loaded hinge via a rib. A plastic material is positioned between the two parts, which begins to flow under pressure. After the spaced sections of the sealing strip have been passed through the seal body and the sealing strip tightened, the seal body is flattened by pressure. The pressure forces the plastic to contact, bind, or penetrate the sealing strip and the spaces between the individual fibers of the sealing strip. This binds the spaced sections of the sealing strip to the seal body. Furthermore, this prevents relative movement of the sealing strips within the seal body. The tensile strength of the sealing strips is not significantly reduced in this process.

[0012] A disadvantage of this seal is the complicated handling during its use.

[0013] US Patent 2010 / 212117 A1 discloses a seal in the form of a cable tie made of biodegradable material. The seal consists of a seal body and a sealing strip. The sealing strip is fixed to the seal body on one side. In an operational state, the seal body can be connected to a portion of the sealing strip. In this operational state, non-destructive separation of this portion from the seal body is impossible. The portion of the sealing strip is spaced apart from the seal body and the free end of the sealing strip.

[0014] A disadvantage of this seal is the possibility of tightening it further, similar to a cable tie. This means that the seal band does not form a fixed eye. Instead, the eye can be subsequently reduced in size. This can happen intentionally or unintentionally. The eye can thus be reduced to a size smaller than the maximum range of motion of the seal.

[0015] Subsequent reduction in the size of the eye can lead to unintentional and uncontrolled destruction of the filling.

[0016] US Patent 2004 / 032332 A1 also discloses a seal in the form of a cable tie made of biodegradable material. The seal consists of a seal body and a sealing strip. The sealing strip is fixed to the seal body on one side. In an operational state, the seal body can be connected to a portion of the sealing strip. This portion is spaced apart from the seal body and the free end of the sealing strip. The connection is designed such that non-destructive separation of this portion from the seal body is impossible. To prevent retightening, an adhesive can be introduced or released into the opening for the free end of the sealing strip in the seal body.

[0017] A disadvantage of this seal is the significantly more difficult handling it makes. Handling is hampered by the introduction or release of adhesive into the opening of the sealing strip within the seal body.

[0018] Another disadvantage is the significantly reduced environmental compatibility of the seal. This is because adhesive can escape uncontrollably into the environment during storage and handling of the seal.

[0019] FR 2 799 864 A1 discloses a seal comprising a seal body and a sealing band. The seal consists of a plastic band with a fastening system of male and female connectors. These connectors cannot be opened without destroying the seal. The sealing band is fixed to the seal body on one side. The seal body consists of two parts that can be permanently sealed together in at least one operating state. The two parts are hinged together. The two parts that can be permanently sealed together in one operating state are also adhesively bonded together. For this purpose, an adhesive layer is arranged between the parts that can be permanently sealed together in one operating state.

[0020] A disadvantage of the delicate construction is that the free end of the sealing strip already comes into contact with the adhesive layer before the sealing body is completed by folding the two hinged parts together.

[0021] Alternatively, a disadvantage of the delicate construction is that the free end of the sealing band is blocked during insertion into the sealing body.

[0022] Furthermore, the design of the seal does not allow for satisfactory adjustment of the eye opening after the free end of the seal band has been inserted into the seal body. This must be done beforehand by shortening the free end. This significantly complicates the handling of the seal. Moreover, it cannot be guaranteed that the resulting section of the seal band will be introduced into the surrounding tissue in a controlled manner when the free end is shortened.

[0023] US Patent 2,639,479 discloses an adhesive seal. The seal consists of a bottom flap, an top flap, and a securing strip. The bottom flap has an opening for the ends of the securing strip. The top flap is hinged to the bottom flap. The opening can be a slit cut into the edge of the bottom flap or a central hole. A strip (such as parcel or gift ribbon) is inserted through the opening with its free ends.

[0024] By folding the upper flap onto the lower flap, the two parts of the tape are fixed by the adhesive layer located on the side of the lower flap facing the upper flap.

[0025] On the side of the bottom flap facing away from the top flap, there is an adhesive layer that secures the adhesive seal to the package or gift with the tape.

[0026] A disadvantage here is the adhesive bond with the object to be sealed, for example, a reusable container. This means the object must be cleaned after the seal is removed, resulting in unnecessary environmental pollution.

[0027] The object of the invention is to create an environmentally friendly seal with improved handling and improved protection against subsequent alteration.

[0028] The problem is solved by the features of claim 1.

[0029] Advantageous embodiments of the invention are set forth in the dependent claims.

[0030] The invention is realized if it concerns a seal with a seal body and a seal band, which preferably consist of biodegradable material.

[0031] Preferably, the biodegradable material consists at least partially of self-compostable material.

[0032] By using a biodegradable material, at least for the seal body, the seal's environmental footprint is significantly improved compared to current technology. If the seal is spontaneously released into the environment, it will compost itself over time. If it is disposed of properly, for example in household or commercial waste, its self-composting ability reduces the overall amount of waste.

[0033] Additional advantages over the prior art, beyond the complete solution of the problem and / or the aforementioned advantages, are listed below.

[0034] The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. The relative sizes of the individual elements in the figures do not always correspond to their actual sizes. Some shapes are simplified, and others are enlarged in relation to other elements for better illustration. Identical reference numerals are used for identical or equivalently functioning elements of the invention. Furthermore, for the sake of clarity, only those reference numerals necessary for describing the respective figure are shown in the individual figures. The illustrated embodiments merely represent examples of how the invention can be implemented and do not constitute an exhaustive limitation. The figures are shown schematically: Fig. 1 a first embodiment of a seal in its initial state and top view, on its first flat side, Fig. 2 the seal made of Fig. 1 on the opposite flat side, Fig. 3 the seal made of Fig. 1 in its initial state in a side view of its longitudinal side, Fig. 4 the seal made of Fig. 1 in its initial state in a side view of its narrow side, Fig. 5 the seal made of Fig. 1 in the initial state in a perspective view, Fig. 6 Seal after Fig. 1 in an intermediate state, in a top view of its first flat side, Fig. 7, the seal made of Fig. 6 in the intermediate state in a top view, Fig. 8 the seal made of Fig. 6 in the intermediate state in a side view of its longitudinal side, Fig. 9 the seal made of Fig. 6 in the intermediate state in a perspective view, Fig. 10 the seal transferred from the intermediate state made of Fig. 6 in a top view, on its first flat side, Fig. 11 the seal made of Fig. 10 in the operating state in a side view of its longitudinal side, Fig. 12 the seal made of Fig. 10 in the operating state in a side view of its narrow side, Fig. 13 the seal made of Fig. 10 In the operating state in a perspective view, Fig. 14 the individual parts of a seal according to a second embodiment with: Fig. 14a a seal body in the unfolded state in a top view Fig. 14 the first seal core adhesive sheet in a top view, Fig. 14c a second seal core adhesive sheet in a top view, Fig. 14d the seal core from Fig. 14d in a side view Fig. 15 the seal made of Fig. 14 in an initial state on its first flat side and Fig. 16 the seal made of Fig. 14 in the initial state in a perspective view of the flat side opposite its first flat side.

[0035] One in Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 , Fig. 5 , Fig. 6 , Fig. 7 , Fig. 8 , Fig. 9 , Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 , Fig. 14 , Fig. 15 , Fig. 16 The seal 01 shown in whole or in part comprises: a sealing body 02 and a starting from an initial state ( Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 , Fig. 5 , Fig. 15 , Fig. 16 ) to transition to an intermediate state ( Fig. 6 , Fig. 7 , Fig. 8 , Fig. 9 ), on the sealing body 02 to form a loop 30 and to maintain an operating state ( Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 ) sealing strip 03 that can be connected to the sealing body 02 in an operational manner.

[0036] At least the sealing body 02 consists of a biodegradable material.

[0037] Preferably, at least the sealing body 02 consists of one or more biodegradable materials.

[0038] Preferably, all functional parts of the seal 01 consist of one or more biodegradable materials.

[0039] Preferably, the entire seal 01 consists of one or more biodegradable materials.

[0040] In other words, the seal 01 comprises the seal band 03 as a flexible means with two end parts 31, 32 which can be operationally connected to the seal body 02.

[0041] The seal 01 can also be called a seal.

[0042] The flexible medium can be designed as a flexible strip.

[0043] The flexible medium and / or the flexible strip can be designed as a rope and / or a chain.

[0044] The flexible medium and / or flexible strip can include a rope and / or a chain.

[0045] The Plombe 01 is characterized by the fact that, for example, at least the functional parts of the Plombe 01 are made of biodegradable material.

[0046] Biodegradable materials (BDMs) must degrade within 6-10 weeks in a large-scale composting facility. BDMs are tested according to the DIN standard EN 13432. They do not necessarily have to be made from biological raw materials. Examples include starch blends, such as those based on corn, or certain polyesters.

[0047] The biodegradable material can be a biodegradable plastic. For example, it could be a biodegradable and bio-based plastic.

[0048] Preferably, the biodegradable material is a compostable material that occurs naturally.

[0049] Preferably, the biodegradable material consists at least partially of self-compostable material.

[0050] Composting, also known as rotting or decomposition, is considered part of the nutrient cycle. In this process, organic material is broken down by soil organisms under the influence of atmospheric oxygen. In addition to carbon dioxide, water-soluble minerals are also released. These act as fertilizers. Some of the intermediate products generated during this decomposition are transformed into humus.

[0051] The biodegradable material could include, for example, the following materials: a biodegradable plastic, and / or a biodegradable and bio-based plastic, and / or a solid material of polylactic acid, and / or cellulose, and / or cellulose esters, and / or celluloid

[0052] The biodegradable material can be based on the aforementioned variants, either as an alternative or in addition to them. Alternatively or in addition, the biodegradable material can include the aforementioned variants.

[0053] Advantageously, the seal body 02, referred to as the base, can be made entirely or partially from a waterproof material, namely cellulose-based, in all described designs.

[0054] Alternatively or additionally, the base or parts of it can be made of waterproof paper or cardboard.

[0055] The sealing band 03 can be a flexible or elastic band. Alternatively, it is conceivable that it is a slack band.

[0056] As a sealing band 03, for example in the form of a flexible element that can be fixed into a loop, it can be a thread, a cord or a band, made from plant-based raw materials.

[0057] The sealing band 03 can alternatively or additionally consist of natural, bio-based, biodegradable polymer.

[0058] In principle, the seal body and the seal band can be made from the same biodegradable material.

[0059] Even an adhesive strip intended for sealing may contain a bio-based, biodegradable plastic.

[0060] Such an adhesive strip may be enclosed within the seal. Alternatively, the adhesive strip may be intended for the purpose of creating a seal. The adhesive strip, if intended, may already be attached to the seal. Alternatively, the adhesive strip may be stored separately from the seal and only inserted when the seal is created. Until it is used, the adhesive strip may be covered with a protective layer. This protective layer may be removable. Such a removable protective layer on an adhesive layer is also called a peel-off layer.

[0061] It is equally important to emphasize that the term Plombenband 03 refers to a strand-shaped element with a maximum extent.

[0062] The strand-shaped element can be formed with any geometry of its cross-section perpendicular to the extension of the strand.

[0063] In this context, the term "band" does not restrict the cross-section to either a flat or a circular geometry.

[0064] If the geometry is flat, the band could most easily be described as a strip.

[0065] If the geometry were circular, the band could most likely be described as a rope, a cord, or a wire.

[0066] For the present seal 01, both the aforementioned and the intermediate geometries of the cross-section of the strand-shaped element are usable.

[0067] The sealing strip 03 can be designed to be flexible, elastic, soft or rigid, without restricting the basic usability of the seal 01.

[0068] The goal of using seal 01 is to minimize any harmful impact on the environment.

[0069] Such harmful environmental impact is typically caused by the spontaneous release of a disused or unused seal (type 01) into the environment. Even the proper disposal of a conventional seal leads to environmental pollution.

[0070] It should be noted that spontaneous entries cannot be completely ruled out.

[0071] Due to the biodegradable design of the seal, the environmental impact is minimal.

[0072] The seal body 02 can be detachably connected to at least two parts of the seal band 03, spaced apart by the circumference of the loop 30.

[0073] In a Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 In the depicted operating state, the seal body 02 can be permanently sealed to the parts of the seal band 03. This involves at least two parts spaced apart from each other by the circumference of the loop 30.

[0074] The sections of the sealing band 03 spaced apart by the circumference of the loop 30 are the end sections 31, 32 of the sealing band 03. An advantageous embodiment of the sealing band 01 provides that the sealing body 02 consists of two parts 21, 22. These parts can be permanently sealed together in an operating state.

[0075] The seal body 02 preferably consists of two parts 21, 22 that can be connected to each other by a hinge.

[0076] The two together in one in Fig. 10 , Fig. 11 , Fig. 12 and Fig. 13 The operating condition shown can be permanently sealed and the connectable parts 21, 22 can be bonded together.

[0077] This is used to create a seal using seal 01.

[0078] This is taken from its in Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 , Fig. 5 depicted initial state in their Fig. 6 , Fig. 7 , Fig. 8 , Fig. 9 The intermediate state shown was converted.

[0079] Initially, only one end section 32 is fixed to the seal body 02. For this purpose, the other end section 31 is passed through two opposing openings and formed into a bay.

[0080] The sealing band 03 is then fixed into a loop 30 using the sealing body 02.

[0081] The operational status of seal 01 is in Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 The elements that separate when opened can, for example, be part of a closure for a container or device to be sealed.

[0082] An adhesive layer can be used to fix the objects together in a space. Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 is arranged in the parts shown.

[0083] Loop 30 is designed in such a way that it can only be destroyed irreversibly.

[0084] Removing the seal 1 is necessary, for example, to gain access to the contents of a container or to a device, or to change a setting.

[0085] The end part 32 is arranged between the two parts 21, 22 of the seal body 02.

[0086] The other part, for example the end part 31, traverses a first part 21 of the two parts 21, 22 of the seal body 02. The seal body 02 can be firmly connected to this.

[0087] According to the invention, the first part 21 has at least two through openings 23, 24 with an intermediate groove 25. The openings 23, 24 are adapted to the dimensions of the sealing strip 03.

[0088] The sealing tape 03 is used here as a flexible medium and / or flexible strip with two end parts, such as a rope and / or a chain.

[0089] The through openings 23, 24 with the intervening groove 25 are adapted to the cross-sectional dimensions of the sealing strip 03. Advantageously, in the operating state (in Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 (shown) the seal body 02 emerges. The seal body 02 is designed as a seal 01 that can be used as a seal.

[0090] The seal body 02 can be designed with jointly connected parts 21, 22.

[0091] Parts 21 and 22 can be in the form of book covers.

[0092] It is a book cover which has two bending strips 23 along a spine.

[0093] A first part, e.g. end part 32 of the sealing band 03, can be fixed in a first book cover or on the bending strip 20.

[0094] In the first part 21, openings 23 and 24, which merge into one another by means of the groove 25 (a feedthrough channel), are additionally provided. The openings 23 and 24 are designed as feedthrough openings for the remaining part of the sealing strip 03.

[0095] Opposite the feedthrough channel, wedges may be arranged that project into the remaining book cover. When the book covers are folded, these wedges can form a labyrinth within the feedthrough channel.

[0096] When the two parts 21, 22 are folded together and, for example, glued together in their operating state, the labyrinth is fixed in the feedthrough channel.

[0097] The remaining game is the remaining final game 31 of the sealing band 03.

[0098] This allows for the creation of an ecological indicative seal in the form of a seal 01 made from biodegradable materials,

[0099] This indicative seal includes a flexible element, which can be fixed into a loop 30, as a sealing band 03.

[0100] The indicative seal comprises a base in the form of a mirror-symmetrical leaf. The leaf, with an inner and outer surface, is designed as a seal body 02, the base of which can be bent inwards.

[0101] The basis for this consists of the first and second parts 21, 22.

[0102] The first and second parts 21, 22 are separated along the line of symmetry by a bending strip 20.

[0103] An end part 32 of the flexible element is attached to the inner surface of the bending strip 20.

[0104] In the first part 21 of the base, two openings 23, 24, also referred to as holes, are formed.

[0105] The openings 23, 24 are provided for the passage of a free remaining other end part 31 of the flexible element.

[0106] The end section 31 serves to transfer the seal 01 from its initial state ( Fig. 1 , Fig. 2 , Fig. 3 , Fig. 4 , Fig. 5 ) about their intermediate state ( Fig. 6 , Fig. 7 , Fig. 8 , Fig. 9 ) to the operating state ( Fig. 10 , Fig. 11 , Fig. 12 , Fig. 13 ).

[0107] Starting from the initial state, the seal can be created.

[0108] A plate of a certain thickness is attached to the inner surface of the first part 21 of the base. The plate does not exceed the thickness of the flexible element.

[0109] The plate has a groove 25.

[0110] This includes the holes for passing through a free remaining end part 31 of the flexible encompassing element during sealing.

[0111] A layer of adhesive with residual tackiness is applied to the inner surface of the second part 22 of the base. This adhesive layer is covered with a protective release liner.

[0112] The outer surface of parts 21, 22 of the base is designed in such a way that identification or other types of information can be applied to it.

[0113] In the base, for example in the first part 21, perforations 26 can be formed between the holes.

[0114] It is important to emphasize that for each end section 31, 32 of the sealing strip 03 an opening 23, 24 with a groove 25 is provided. This groove 25 extends to an opposite edge.

[0115] This allows both end parts 31, 32 of the sealing strip 03 to be inserted into a separate groove 25 through a separate opening 23, 24 for sealing.

[0116] When the two parts 21, 22 of the seal body 02 are folded together, these parts 21, 22 are secured in their respective own groove 25.

[0117] This also creates an ecological indicative seal in the form of a seal 01 made of biodegradable materials.

[0118] This indicative seal also includes a flexible element, which can be fixed into a loop 30, as a sealing band 03.

[0119] This indicative seal also includes a base in the form of a mirror-symmetrical leaf with an inner surface 202 and an outer surface 201.

[0120] The base of this indicative seal can also be bent inwards.

[0121] The basis consists of the first part 21 and the second part 22.

[0122] The first part 21 and the second part 22 are separated along a line of symmetry by a bending strip 20.

[0123] An end part 32 of the flexible element is attached to the inner surface of the bending strip 20.

[0124] The sheet could be a 200 mm sealing body sheath, ( Fig. 14 , Fig. 15 , Fig. 16 ).

[0125] A plate is attached to the inner surface as the first part 21 of the base.

[0126] The plate could be a 203-piece filling core ( Fig. 14 , Fig. 15 , Fig. 16 ).

[0127] The plate has two through-holes for threading through a remaining free end section 31. The end section 31 is flexible and can be formed into a loop.

[0128] A recess is formed between the holes. The recess is preferably in the form of a recessed groove 25. This allows the loop 30 to be secured during sealing.

[0129] A through groove 25 is also formed for each hole, which leads from the hole to the nearest edge of the base.

[0130] A layer of adhesive with residual tackiness is applied to the inner surface of the second part 22 of the base.

[0131] This is covered with a protective peel-off layer.

[0132] The peel-off layer has a protective layer ( Fig. 14c , Fig 15 and Fig. 16 ).

[0133] The outer surface of the base is designed to allow for the application of an identification or other type of information, a biodegradable protective label, or an RFID label.

[0134] For example, such an outer surface could be an outer surface 201 as shown in the embodiments illustrated ( Fig. 14 , Fig. 15 , Fig. 16 ) mentioned seal body mantle 200.

[0135] At the seal 01 ( Fig. 14 , Fig. 15 , Fig. 16 ) the sealing body 02 consists of three parts 21, 22 which can be inseparably sealed together at least in one operating state.

[0136] The sealing band 03 is arranged with a first part, preferably with a first end part 32, between a first part 21 and a second part 22 of the sealing body 02.

[0137] Advantageously, the first end section 32 is arranged in the area of ​​a bending strip 20.

[0138] The bending strip 20 connects the first part 21 with the second part 22. The second part 22 comprises two second parts 28, 29 connected to each other by another bending strip 20.

[0139] The seal body 02 ( Fig. 14 , Fig. 15 , Fig. 16 ) comprises a seal body mantle 200.

[0140] This can be found on its shown exterior surface area of ​​201 ( Fig. 14a ) be provided with information. This information is represented by a schematically recognizable control number ( Fig. 16 ).

[0141] An inner surface 202 opposite the outer surface 201 of the plornben body mantle 200 can also be provided with information.

[0142] This could be, for example, instructions for creating the seal, perhaps in a step-by-step numbered sequence.

[0143] A seal core 203 is arranged on the inner surface 202 of the seal body shell 200.

[0144] The sealing core 203 is advantageously arranged in the area of ​​the section encompassed by the second part 22 of the sealing body 02.

[0145] The sealing core 203 can be particularly advantageously attached to the inner surface 202 of the sealing body shell 200 by means of a sealing core adhesive sheet 204. For this purpose, the sealing core adhesive sheet 204 is arranged between the sealing core 203 and the inner surface 202 of the sealing body shell 200.

[0146] Furthermore, another sealing core adhesive sheet 205 can be arranged on the side of the sealing core 203 facing away from the sealing core adhesive sheet 204.

[0147] Seal core adhesive sheet 204 is a first seal core adhesive sheet 204. Seal core adhesive sheet 205 is a second seal core adhesive sheet 205.

[0148] Several second sealing core adhesive sheets 205 may be provided to ensure a particularly tamper-proof seal ( Fig. 15 ).

[0149] It is important to note that the term "adhesive sheet" is representative of a wide variety of conceivable designs for adhesive layers.

[0150] However, at least in the case of the second sealing core adhesive sheet 205, the adhesive layer is advantageously covered until its use, for example, by a peelable protective layer.

[0151] A covered adhesive layer is represented, for example, by a peel-off tab 206 ( Fig. 14c , Fig. 15 , Fig. 16 ).

[0152] The sealing core 203 has circumferential narrow sides 207, 208, 209, 210 as well as a top and a bottom surface. These are connected to each other by means of the narrow sides 207, 208, 209, 210.

[0153] The seal core 203 is provided with a groove 25. The groove 25 can be designed as a slot in the seal body 203. The groove 25 extends from the top to the bottom of the seal body 203.

[0154] The groove 25 leads from a narrow side 207 of the seal core 203 into the seal body 203.

[0155] The groove 25 ends at the seal 01 in the seal body 203 before reaching its narrow side 208 opposite the narrow side 207 ( Fig. 14 , Fig. 15 , Fig. 16 ).

[0156] The groove 25 serves to guide the end part 31 of the sealing band 03, which is free in the initial state, in the sealing body 02.

[0157] A mouth widening 211 may be provided to facilitate the insertion of the free end part 31 of the sealing band 03 into the groove 25.

[0158] The seal body shell 200 can be provided with holes forming openings 23, 24 in a section that can be folded onto the seal core 203 for transfer to the operating state.

[0159] These openings 23, 24, in conjunction with the groove 25, serve to guide the end part 31 of the sealing strip 03 correctly.

[0160] Advantageously, the section that can be folded onto the seal core 203 is the section of the seal body mantle 200 encompassed by the first part 21 of the seal body 02.

[0161] One or more additional openings 27 can serve for the additional passage of the end part 31 and / or for external control of its correct execution.

[0162] An auxiliary marking can indicate the direction of the end part 31 of the seal band 03 to be led to create a loop 30 within the seal body 02.

[0163] In addition, in the opened state of the seal body 02, which does not yet correspond to the operational state, numbers may be provided, for example, on individual sections of the seal body shell 200 and / or in the area of ​​the openings 23, 24.

[0164] This allows the correct passage of the end part 31 through the seal body 02 by simply following the ascending numbering.

[0165] Advantageously, at least on the outer surface of one of the parts 21, 22 of the sealing body 02, also referred to as the base, a temperature indicator can be applied.

[0166] It is important to emphasize that the aforementioned wedges can be used in all versions of the Plombe 01.

[0167] The wedges are particularly advantageous in conjunction with a through-channel formed, for example, by a groove 25.

[0168] In this, the wedges form a labyrinth. The labyrinth immovably fixes an end section 31, 32, preferably the remaining free end section 31 of the sealing band 03, in the feedthrough channel.

[0169] The seal 01 can alternatively or additionally exhibit one or a combination of several of the described features.

[0170] The Plombe 01 can be used, for example, to seal containers or devices, such as on their housing, for example in international trade in goods and merchandise, as a customs seal.

[0171] By affixing the seal 01 to the closure of a container or device, a process known as sealing, it can be determined whether a container or device has been opened without authorization after sealing.

[0172] The same applies to other uses of the seal 01.

[0173] It can serve, for example, as proof that a setting on a device has not been changed, as well as a substitute for an admission ticket, to render technical connections unusable without deactivation, and in the case of military facilities.

[0174] The invention is not limited by the description based on the exemplary embodiments.

[0175] Rather, the invention encompasses every new feature as well as every combination of features.

[0176] This includes in particular any combination of features in the claims, even if that feature or combination itself is not explicitly stated in the claims or embodiments.

[0177] The invention is particularly applicable in the field of manufacturing customs seals and the like.

[0178] Furthermore, the invention is commercially applicable in the field of manufacturing and operating plants and devices where an unauthorized change to a setting or unauthorized access must be subsequently detectable by means of a broken seal.

[0179] The invention has been described with reference to preferred embodiments. However, it is conceivable to a person skilled in the art that modifications or changes to the invention can be made without departing from the scope of protection of the following claims. Bezugszeichenliste
