       BACKGROUND 
       [0004]    The invention relates to methods for anti-tamper protection of packaged securities and valuable items sent or transferred from one juridical or physical person to another. 
         [0005]    Transferring packaged securities, valuable items, jewelry or money involves a risk that others may attempt to open up the packaging, tamper with security features, or replace packaged items with counterfeits. However, despite these complications transferring such packaged items is still in high demand, thereby requiring reliable anti-tamper protection features, and protection against counterfeiting. 
         [0006]    Known is a technology for protection against counterfeiting of, and tampering with, packaged items. See www.apostrof-print.ru. Protective labels with an electronic radio frequency identification code attached to articles makes it possible to monitor and control the movement of packaged items. Moreover, invisible ink can be applied to a bar code identifiable with a scanner, as well as seals. 
         [0007]    The known technology has drawbacks because tamper protection is not very reliable and protection against counterfeiting is weak. 
         [0008]    Known is a method for protection, and protective packaging, for a precious stone, pearl, coin, postage stamp with philatelic value, and other valuable items. See RF [Russian Federation] utility model patent No. 013589 published 06.30.2009, for the method prototype. The utility model comprises an upper and lower component made of a transparent polymer material, with the upper component having at least one transparent enclosure made, for instance, in the form of a cell designed for placement of at least one of said objects. An ornamental printed impression is located on the outside surface of the packaging upper component. An irreversibly destroyable layer is located on the inside surface of the lower packaging component and made, for instance, in the form of a holographic coating designed for protecting the packaging against counterfeiting and for detecting tampering. The upper and the lower component of packaging are joined adhesively by means of an irreversibly destroyable layer. 
         [0009]    Self-adhesive laminated paper is placed between the ornamental printed impression and the outside surface of the upper component. The irreversibly destroyable layer comprises at least one transparent area formed by double laminate and located under the transparent housing of the upper packaging component. The ornamental printed impression and the self-adhesive laminated paper overlap the irreversibly destroyable layer less its transparent area. Herein, the lower packaging component is made of thickened laminate. The self-adhesive laminated paper has protective means comprising an imprint applied using special inks and/or fibers that are visible when exposed to ultraviolet radiation. 
         [0010]    Among the drawbacks of the known coded material used for packaging of valuable or important items or documents are the large size of the resulting packaging that exceeds the size of the packaged item due to the larger width of its side walls, and a low degree of protection which makes tampering possible by separating the layers, for instance, by dissolving the adhesive compound. 
         [0011]    Known is a packaging in the form of capsules for bullion and coins of the Central Bank of the Russian Federation, as well as for other countries&#39; coins, which makes it possible to preserve the original appearance of products for many years. See Albi transparent bubble packaging www.coinbox.ru.—the device prototype. 
         [0012]    Capsules for coins are made of high-quality polystyrene. The newest technologies make it possible to provide sufficient transparency of the product, as well as high strength, reliability and durability of the material. The capsule for coins is made in the form of a container with a cylindrical housing of appropriate height, having a bottom and cover. The capsule for bullion is made in the form of a rectangular container with the bottom and cover. 
         [0013]    Among the drawbacks of the known design of the capsule are its use for storing low-value coins and its uselessness for storing valuable and expensive coins. This is because it is possible to open the capsule and replace a valuable coin with, for instance, a counterfeit, and then reattach the cover to the capsule housing. 
         [0014]    The object of the claimed invention is to develop packaging technology and design that ensures reliable anti-tamper protection. 
       SUMMMARY 
       [0015]    The stated object of the invention is achieved by a combination of known technology features including making the packaging comprised of at least a single-layer material with protective means destroyable upon tampering, and new features. The new features are the following: a protective means destroyable upon opening the packaging is provided on the outside or inside of the packaging material and/or in the structure of monolithically joined layers of packaging material; the surfaces of each packaging component that mate when joined are made parallel or at an angle of 0.01°-90.0° relative to each other, with a lock joint made in the form of at least one step between the mating surfaces; and at least one of the lock joint surfaces has at least one protective means destroyable upon tampering. 
         [0016]    For the protective means destroyable upon tampering, including additional protective means, the following are used: images, including a shadow image, of a code, optical lines, waveguides, radio frequency bar codes, deep-etched offset printing including micro-texts, watermarks, filigree and/or superimposed patterns invisible under normal conditions, fluorescent, metallized and magnetic inks and fibers, marks, protective threads and stripes, perforations, diffraction gratings, holograms or marking made using an electric discharge method, a material that oxidizes and changes its color upon tampering, for instance a manganese compound, mechanofore plastic that changes its color under mechanical load, a mixture of iodine alcoholate and dextrin which is applied to a part of mating surfaces and disappears with air access, or combinations thereof. 
         [0017]    At least a single-layer packaging material with a protective means is made monolithic by joining the layers by gluing, or by a chemical or thermal joining with at least one transparent area for visual inspection of the packaged item. 
         [0018]    The joined mating surfaces of the packaging components with a lock joint are 1.0-100.0 mm wide and made in the form of at least two stripes along the edges of the packaging mating components. 
         [0019]    The protective means in the form of additional optical lines destroyable upon tampering is provided at an at least one specified incline angle of 5.0°-90.0° to the plane of the material. In an optional embodiment, the destroyable-upon-tampering protective means in the form of a waveguide or optical lines on the contact surface of the packaging mating surfaces is placed in accordance with a specified algorithm, with the lines intersecting each other at least twice or placed at a specified distance from each other, and/or at an angle to each other, or being wavelike, or forming geometric figures (e.g., a circle, a square, a rectangle, or a regular or irregular rhomb). 
         [0020]    For the packaging material, a strong resilient wear-resistant material, for instance biaxially or monoaxially oriented polypropylenes or co-extrusive polyethylenes, is used. 
         [0021]    As an additional protective means, necessary information about the item including the logo, the organization name, packaging manufacturing date, the packager, and the sender&#39;s and recipient&#39;s addresses, is applied to the packaging surface that is comparable to the packaged item&#39;s dimensions, using ink invisible under normal conditions. 
         [0022]    The stated design object of the invention is achieved by a combination of known features including packaging made of at least a single-layer material with a protective means, and new features: packaging made of at least two layers of material monolithically joined by means of a chemical joint, or gluing, or heat sealing with copolymers or co-extrusive polyethylenes, in the form of a container with a housing, bottom and cover, or in the form of tape used for banding the packaged item, wherein the joined surfaces of packaging components or tape sides are made parallel or at an angle of 0.01°-90.0° relative to each other, with a lock joint made in the form of at least one step between the mating surfaces, and at least one of the lock joint surfaces has at least one additional protective means destroyable upon tampering. 
         [0023]    The lock joint on mating surfaces of packaging components is made three-dimensional; its height is 1.5-50 times larger than the thickness of the packaging material, and its cross-section is made in the form of a broken or curved line connecting the levels. 
         [0024]    The container bottom, or part thereof, in the form of at least one strip with a width equal to 0.2-0.5 of the bottom diameter or width, is made convex towards the inside of the container in order to prevent the packaged item from moving inside the container during its inspection and transportation. 
         [0025]    The lock joint on mating surfaces of the packaging components is made in the form of corrugations inclined at an angle of 10.0°-75.0° relative to each other and, as an additional protective means, incline angles of the corrugations can be made equal, increasing, decreasing or alternating. 
         [0026]    The novelty of the method and invention claimed is to provide a destroyable-upon-tampering protective means on the outside or inside of a packaging material and/or in the structure of monolithically joined layers of packaging material, wherein the mating surfaces of each packaging component are made parallel or inclined at an angle of 0.01-90.0° relative to each other, with a lock joint made in the form of at least one step between the mating surfaces, and at least one additional protective means destroyable upon tampering provided on one of the lock joint surfaces. 
         [0027]    Thus, providing at least one additional protective means, destroyable upon tampering, on the outside or inside of packaging material or in the structure of monolithically joined layers of packaging material prevents penetration between the layers and through packaging material without damaging the protection because the monolithically joined packaging layers do not allow for opening the packaging without visible damage. 
         [0028]    Making the mating surfaces of each packaging component parallel or inclined at an angle of 0.01-90.0° relative to each other, with a lock joint made in the form of at least one step between the mating surfaces, creates even more difficulties for tampering. Thus, upon penetration through the joined surfaces to the lock joint of the surfaces, it is impossible to enter the second level without damaging packaging layers and the protective means. This is because the tampering tool will encounter an obstacle, i.e., the step between the joined surfaces. 
         [0029]    The following are additional technology features intended for specific performance of the main features and for achieving the stated technical result of the invention: using, as the protective means, destroyable-upon-tampering, including additional protective means, of images, including a shadow image, of a code, optical lines, waveguides, radio frequency bar codes, deep-etched offset printing including microtexts, watermarks, filigree and/or superimposed patterns invisible under normal conditions, fluorescent, metallized and magnetic inks and fibers, marks, protective threads and stripes, perforation, diffraction gratings, holograms or marking made using the electric discharge method, a material that oxidizes and changes its color upon tampering, for instance a manganese compound, mechanofore plastic that changes its color under mechanical load, a mixture of iodine alcoholate and dextrin which is applied to a part of mating surfaces and disappears with air access, or combinations thereof, providing at least a single-layer packaging material with a protective means that is made monolithic by joining the layers using gluing, a chemical or thermal joint, with at least one transparent area for visual inspection of the packaged item, making the joined mating surfaces of packaging components with a lock joint that is 1.0-100.0 mm wide and in the form of at least two stripes located along the edges of mating components of the packaging, providing the protective means in the form of additional optical lines destroyable upon tampering that are at an at least one specified incline angle of 5.0°-90.0° to the plane of the material, placement of waveguides or optical lines destroyable upon tampering on the contact surface of the packaging mating surfaces in accordance with a specified algorithm and intersecting each other at least twice or placed at a specified distance from each other and/or at an angle to each other, or being wavelike, or forming geometric figures-a circle, a square, a rectangle, or a regular or irregular rhomb, the use of a strong resilient wear-resistant material, for instance biaxially or monoaxially oriented polypropylenes or co-extrusive polyethylenes, as the packaging material, as well as applying to the packaging surface that is comparable to packaged items dimensions, as an additional protective means, the necessary information about the item including the logo, the organization name, packaging manufacturing date, the packager, and the sender&#39;s and recipient&#39;s addresses using ink invisible under normal conditions. 
         [0030]    The novelty of the proposed packaging is the making of at least two layers of material monolithically joined, by means of a chemical joint, or gluing, or by means of heat sealing with copolymers or co-extrusive polyethylenes, in the form of a container with a housing, bottom and cover, or in the form of a tape used for banding the packaged item, wherein the joined surfaces of packaging components of tape sides are made parallel or at an angle of 0.01°-90.0° relative to each other, with a lock joint made in the form of at least one step between the mating surfaces, and at least one of the lock joint surfaces having at least one additional protective means destroyable upon tampering. 
         [0031]    Thus, making the protective means monolithic in the structure of the packaging material prevents unauthorized penetration through the packaging, or an attempt to separate the layers, because the means do not allow tools of any design to separate one layer of material welded or glued to another layer, or to penetrate through the material without visible destruction of the material. 
         [0032]    Making the joined surfaces of package components at an incline angle of 0.01-90.0° makes it possible to firmly join the container housing and cover, or one tape edge with its other edge during banding, by applying a specified load to them when joining and thus to prevent their loose connection. 
         [0033]    Making the joined surfaces of package components with a lock joint made in the form of at least one step between the mating surfaces additionally and securely prevents unauthorized penetration into the packaging because during penetration the tool would encounter an obstacle in the form of a step in the lock joint, and for the tool to penetrate further, damage to packaging and hence to the protection is unavoidable. 
         [0034]    The following are additional design features furthering the achievement of the stated object of the invention: making the lock joint on mating surfaces of packaging components three-dimensional, with the height that is 1.5-50.0 times larger than the thickness of packaging material, making the cross-section in the form of a broken or curved line connecting the levels, making the container bottom, or part thereof, in the form of at least one strip with the width equal to 0.2-0.5 of the bottom diameter or width and convex towards the inside of the container in order to prevent the packaged item from moving inside the container during its inspection and transportation, and making the lock joint on mating surfaces of packaging components in the form of corrugations inclined at an angle of 10.0°-75.0° relative to each other, wherein, as an additional protective means, incline angles of the corrugations can be made equal, increasing, decreasing or alternating. 
         [0035]    According to patent information retrieval that was conducted, no combination of features proposed as the invention has been found in pertinent art, therefore, the proposed features have novelty. 
         [0036]    The combination of the proposed new features and the known ones does not follow expressly from pertinent art and is not obvious, which makes it possible to consider said features as having the level of invention. 
         [0037]    The proposed features presented in this application make it possible to make a conclusion of their industrial applicability.

     DESCRIPTION 
       [0055]    The proposed method is carried out using packaging made in the form of, for instance, a container, in the form of a cube, comprising housing  1  made of at least a double-layer material with protective means  2  inserted into its structure. Upper section  3  of housing  1  and lower section  4  of cover  5  are made inclined at an angle of 0.1°-90° and with a lock joint made with at least two-level surfaces  6  and  7  (see  FIG. 2 ), with steps  8  provided along the perimeter between the surfaces. Additionally, at least one protective means  9  is applied on level surfaces  6  and  7 . Versions of lock joints are also shown in  FIG. 3  where a), b), g), d) are lock joints with their cross-section in the form of broken lines and b) in the form of convex lines. 
         [0056]    In cylindrical housing  10  of a container, for instance, for coins, upper section  11  of the housing and lower section  12  of cover  13  are made inclined and at least two-level or with a lock joint-see  FIG. 4  and  FIG. 7 . Dotted lines  14  show possible increase of the container height. Container bottom  15  or part thereof in the form of for instance diametrically located strip  16  the width of which is equal to 0.2-0.5 of the diameter or width of container bottom  15  is made convex, to prevent coin  17  from moving inside the container. The material for packaging items of indeterminate shape is made in the form of tape  18  with two-level strips  19  and  20  along its longitudinal edges or with a lock joint, with additional protective means  21  applied to them made, for instance, in the form of optical lines intersecting in accordance with a specified algorithm and at a specified angle. The additional protective means is applied on the bottom side of strip  19 , and on strip  20  the protective means can be applied on its top side. Using tape  18  it is possible to reliably package items with different shapes—cylindrical item  22 , item  23  in the shape of a parallelepiped, and item  24  of indeterminate shape, because the tape that envelopes the packaged item follows the item&#39;s surface. 
         [0057]    Waveguides  25  and optical lines  26  can be made intersecting, parallel, at an angle to each other, or according to a specified algorithm, and can be made in the form of regular and irregular geometric figures. Bar code  27  on at least one of mating surfaces of, for instance, a cylindrical container can be applied using either visible or invisible ink, as well as ink or paint that changes its color or disappears upon tampering. Corrugations  28  on mating surfaces can be made at equal as well as at different incline angles, including their combinations, and making their surfaces two-level with a lock joint makes tampering much more difficult. 
         [0058]    The proposed method is implemented as follows. To package valuable and important items, documents, bullion, decorations, first either a container corresponding to dimensions of the packaged item is made or tape is used. In doing so, at least one protective means  2  is applied into the structure of the container or the tape material and/or to its outside surfaces, and additional protective means  9  destroyable upon tampering is applied to mating surfaces of the upper section of housing  1  and the bottom surface of cover  5  that are inclined at an angle of 5.0°-90.0° relative to the plane of the material and made in the form of a lock joint with step  8 . 
         [0059]    An item is packaged in a container as follows. Depending on artistic embodiment of the packaged item and particular features of images on it, a part of the container, for instance, its side walls, is made transparent for visual inspection without opening the packaging. 
         [0060]    After the packaged item is placed in the container and steps are taken to prevent the item, for instance, of coin  17 , from moving in container housing  10  using, for instance, convex container bottom  15  or convex strip  16  of the container bottom, a bonding compound is applied to mating surfaces—the outside surface of upper section  3  of the housing of container  1  and inner inclined surface  4  of the bottom section of the cover, and the surfaces are firmly joined to each other using a chemical or thermal joint, or by gluing. Here, two-level surfaces  6  and  7  of the lock joint of the container housing are connected to identical surfaces of the lock joint of the inside inclined surface of cover  5 , with tight mating of their steps  8 . Likewise, other items -coins, bullion, paintings, bills, etc., are packaged in containers of various shapes and geometries. 
         [0061]    Packaging of items using tape is done by successively wrapping (banding) the packaged item with tape  18 . During wrapping, protrusion  8  of each subsequent turn of the tape is connected to the protrusion of the preceding turn of the tape using strips  19  and  20 . In doing this, a bonding compound can be applied to the surface of strip  19  underneath, and the additional protective means can be applied to surface  20  and vice versa, bonding compound can be applied to the bottom surface of strip  20  and at least one protective means can be applied to top surface  19 . 
         [0062]    To package fairly heavy items, for instance bullion, containers corresponding to the bullion shape are used, and three-dimensional lock joints with their cross-sections in the form of broken lines or lines with varying curvature are provided along the container perimeter—see  FIG. 3  a), b), w), g), d). Anti-tamper protection components can be provided between the surfaces of lock joints. 
       Best Embodiment of Invention 
       [0063]    To package a silver coin, a container corresponding to its dimensions in terms of height and diameter was made of a transparent double-layer material-biaxially oriented polypropylene, and a protective means in the form of bar code  27  was embedded into the monolithic structure of the container using ink invisible under normal conditions. Top surface  11  of the inclined section of container housing  10  and the inside surface of bottom part  12  of cover  13  were made two-level at an angle of 45° and 5 mm wide-each level 2.5 mm wide, with steps  8  formed between the levels. Container bottom  15  was made convex towards the inside of the container. After coin  17  was placed onto container bottom  15  convex towards the inside of the container, the convex bottom elastically pressed coin  17  along the perimeter of the top edge to top inclined section  11  of the container housing, and the coin was not moving during shaking. Adhesive composition of co-extrusive polyethylene was applied to the first, closest to the edge, surface identical to surface  6  of housing  10 , and a bar code using invisible ink and adhesive composition was applied to the second, farthest from the edge, surface identical to surface  7  of the outside inclined surface of upper section  4  of container housing  10 , then the surfaces were firmly joined to each other. 
         [0064]    In doing this, step  8  of the cover was firmly joined with the housing step. When experimental tampering was attempted, the housing and cover steps were damaged, and the bar code applied with invisible ink was also destroyed. 
       Embodiment of Invention 
       [0065]    At the same time, work was performed to package a roll in the form of a cylinder using double-layer tape with protective fluorescent fibers embedded into its structure and made according to a specified algorithm, specifically parallel to each other. A 10 mm wide layer of adhesive composition of co-extrusive polyethylene was applied to the first from the edge inside surface  19 , and an image in the form of lines intersecting at a specified angle made using invisible ink, as well as adhesive composition were applied to outside surface  20  of the tape. Successive turns of tape  18  were carefully laid onto each other with their lateral sides, with tight contact between the steps and surfaces  19  and  20  of tape  18 . After a 30-minute hold, experimental opening of the packaging was performed. 
         [0066]    In doing this, the tape was damaged—its edge was ruptured, the image made with invisible ink was damaged, and steps between surfaces  19  and  20  were also damaged. 
       Embodiment of Invention 
       [0067]    To package a bullion, a rectangular container corresponding to bullion dimensions was used. Originally, the joined surfaces of the container housing and cover were made flat. Two waveguides were placed parallel to each other onto the bottom surface along the container perimeter. Then, after the bullion was placed in the container a π-shaped lock joint (see  FIG. 3   a ) was formed along the bullion perimeter by means of heat-sealing using a heated mold. As the result of changing the geometry of the container edges the parallelize of the placed waveguides was preserved. 
         [0068]    During experimental opening, the container material at the lock joint was damaged, and both waveguides were also damaged. 
       INDUSTRIAL APPLICABILITY 
       [0069]    Housings can also be joined with container covers by gluing or a chemical joint; when doing this, it is first necessary to make a lock joint of appropriate geometry along the perimeter of the joined surfaces. 
         [0070]    The use, as the protective means destroyable upon tampering, including additional protective means, of images, including a shadow image, of a code, optical lines, waveguides, radio frequency bar codes, deep-etched offset printing including micro-texts, watermarks, filigree and/or superimposed patterns invisible under normal conditions, fluorescent, metallized and magnetic inks and fibers, marks, protective threads and stripes, perforation, diffraction gratings, holograms or marking made using the electric discharge method, a material that oxidizes and changes its color upon tampering, for instance a manganese compound, mechanofore plastic that changes its color under mechanical load, a mixture of iodine alcoholate and dextrin which is applied to a part of mating surfaces and disappears with air access, or combinations thereof makes it possible in each specific case to create reliable packaging protected from tampering, and the combination of types of protection with making the material at least double-layer and monolithic leaves no room for doubting the reliability of the protection. 
         [0071]    Depending on packaged item dimensions, the additional protection means is applied to the lock joint surface in 1.0-100.0 mm wide strips. When a strip width is less than 1 mm, there are fewer options in selecting applied protective means, and applying an additional protective means on a strip wider than 100 mm is impractical because in this case the reliability of protection increases insignificantly. 
         [0072]    Making easily damageable optical lines applied at an angle of less than 5.0° is a fairly complicated process. 
         [0073]    Making optical lines applied at various angles in accordance with a specified algorithm ensures reliable anti-tamper protection. 
         [0074]    Using as packaging material a strong elastic wear-resistant material, for instance, biaxially or monoaxially oriented polypropylenes ensures long-time storage and use of the packaged items. Applying to the packaging surface that is comparable to the packaged item dimensions, as an additional protective means, the necessary information about the item including the logo, the organization name, packaging manufacturing date, the packager, and the sender&#39;s and recipient&#39;s addresses using ink invisible under normal conditions keeps the packaging transparent, convenient to handle and not burdening when examining the packaged item. 
         [0075]    Making at least a two-level joint with various angles of lock joint surfaces ensures reliable packaging of heavy and bulky items. 
         [0076]    Making a lock joint with the height that is 1.5-50.0 times larger than the thickness of packaging material does not create unnecessary cluttering of the packaging. Elastic pressing of the packaged item in the container by means of the convex bottom or its part contributes to long-term use of the packaged item. 
         [0077]    Providing corrugations along the container perimeter with inclined angles of 10.0°-75.0° in various variations provides additional anti-tamper protection. 
         [0078]    The use of the proposed method will make it possible to provide packaging that is reliable and protected against tampering, is made of a synthetic polymer or other material, and will make it possible to reliably use an item packaged using the proposed method in the proposed packaging as a means of payment, and to reflect its real price and value without performing expert examination of the authenticity of the packaged item. Here, the integrity of the packaging and its protection means is checked using appropriate detectors. 
         [0079]    A packaged item can stay in circulation for a long time while preserving its protection features and packaging integrity. And the packaging can be made of the same materials that are used for making polymer bills. 
         [0080]    The author has developed engineering documentation and performed pilot production of several types of the packaging in the form of containers and using tape with two-level contact surfaces and the simplest protective means. Testing has demonstrated high reliability of protection of items packaged in the proposed containers and wrapped with tape.
