Description

FIELD OF TECHNOLOGY

The invention relates to packaging for tobacco products and to multiple packaging, i.e. to a packaging “unit” containing multiple packages of tobacco products. In addition, the invention relates to a blank for the manufacture of packaging for tobacco products.

BACKGROUND

Tobacco products, preferably smoking articles, such as, for example, cigarettes, are often contained in disposable packages (“cigarette packs”) having a substantially cuboid or parallelepiped shape. Typically, four side walls (e.g., front wall, rear wall, left wall, and right wall) extend from the lower wall and form an outer box together with the lower wall, leaving a hole on the upper side opposite the lower wall, which allows access to smoking articles . The hole is usually closed by a lid, which is usually rotatably connected to the rear wall. However, many different packages are known, ranging from soft packs to classic cigarette boxes. Recently, packaging for tobacco products deviating from the classical form of a cuboid or parallelepiped has become increasingly popular. For example, there are packages having beveled edges and a diamond-shaped cross section viewed in a plane substantially perpendicular to the direction of the maximum extent of the package. Instead of using bevels / chamfers for the longitudinal edge parts of the package, the latter can also be made with rounded edge parts.

It is often desirable to attach accessories such as a lighter or ashtray to the appropriate packaging to prevent loss. Many different technical approaches to solving this problem are known from the prior art. They range from holding frames to hook and loop fastening systems (Velcro strips), which are disclosed by way of example in WO 2011/005855 A1.

The general idea underlying all these approaches is to prevent the loss of one of two items that can be used together. For example, the loss of a lighter is prevented by attaching it to a pack of cigarettes. However, all such packages or systems are characterized by the desire to avoid situations where smoking accessories are easily lost and therefore attached to the respective package.

SUMMARY OF THE INVENTION

An object of the present invention is to provide packaging or multiple packaging for tobacco products, which per se can easily be found. An additional objective of the present invention is to develop a blank for the manufacture of such packaging.

In accordance with one aspect of the invention, packaging for tobacco products is provided. The package has an outer box containing a bottom wall and side walls (for example, a front wall, a back wall, left and right walls) extending substantially perpendicular to the bottom wall. The outer box contains an internal space and has an opening that is located opposite the bottom wall or in the side wall of the package. A lid may be provided that is pivotally connected to one of the side walls (e.g., the back wall) to open and close the package. The package further comprises a permanent magnet, which is located in the inner space and is fixedly fixed in the inner space.

The permanent magnet may preferably be located in close proximity to the longitudinal edge portion of the outer box. The longitudinal edge portion is a zone in which adjacent walls of the outer box are connected.

A permanent magnet, within the meaning of this term, can be an ordinary solid-state permanent magnet, magnetic foil, magnetic paste, for example, a polymer dispersion containing magnetic particles, or even a stack or some configuration of a plurality of smaller magnets arranged in a certain order, functioning together as one permanent magnet.

“Fixed attachment” means that the permanent magnet is attached to the package in such a way that the magnet can only be detached by at least partially damaging or destroying the package.

For permanent attachment of the permanent magnet, the permanent magnet can be glued to the package.

Alternatively, the permanent magnet may be contained in the socket for non-removable attachment.

In addition, self-adhesive fixation may be used to permanently attach the permanent magnet.

A self-adhesive layer or self-adhesive tape on a permanent magnet or on the surface of the package can be used for fixed attachment.

One or more of the previously mentioned means can be combined to permanently attach a permanent magnet.

The magnet and the packaging preferably form an integral whole. This reduces the possibility that the magnet or parts thereof may become detached from the package.

The tobacco packaging is preferably configured to magnetically attach to a variety of different household items, preferably household items, such as a refrigerator door, a metal door frame, a metal frame of a lamp or table, and therefore is configured to be easily searched / removed and stored in preferred location. However, also in other places, for example in a car or boat, there are many different places containing magnetizable material for attaching the package. In addition, it is preferable that the package is attached to the respective objects through the use of magnetic field strength. In particular, unlike solutions that are known from the prior art (which involve the use of, for example, adhesive, or glue, or the like), the package is capable of being disconnected without leaving a residue or leaving traces. Another advantage is that there is no need for complementary components, such as a frame or lining for fastening means in the form of hooks and loops.

In accordance with one aspect of the invention, the outer box may have a beveled edge portion. Preferably, the package has at least partially a polygonal, hexagonal, octagonal or circular cross-sectional shape or a cross-sectional shape that is half an octagonal shape. The cross-sectional shape may relate to a plane substantially perpendicular to the maximum extent of the package. A half octagon is an octagon that is cut in half and has one flat surface that is perpendicular to the respective adjacent surfaces. The beveled edge part forms the edges related to the aforementioned cross-sectional shapes. In this case, the permanent magnet can be fixedly attached to the beveled edge part of the outer box.

In accordance with one aspect of the invention, the outer box has a rounded edge portion. In this case, the rounded edge portion may also correlate with a cross-sectional shape in a plane substantially perpendicular to the maximum extent of the package. In this case, the permanent magnet can be fixedly attached to the rounded edge portion of the outer box.

This placement of the permanent magnet in the inner space of the outer packaging box provides the ability to connect together groups of packages. Packages may be attached to each other, or the entire group may be attached to a third item. Single packages can be removed from this group or inserted into this group while ensuring the possibility of maintaining reliable fastening of single packages to each other.

The ability to bond multiple packages together with the formation of a group of packages is preferred for wrapping the group. In particular, if packs of cigarettes can be packaged together to form a group of packs of cigarettes, handling the group of packs during the packaging process can be simplified.

According to a preferred embodiment, the wall thickness of the outer box mainly determines the minimum distance between the permanent magnet, which is located on the inner surface of the outer box, and the corresponding object. The holding force for magnetically attaching the package to the third item increases as the distance between the permanent magnet and the corresponding (magnetizable) item to which the package is to be attached decreases. The minimum distance provides the maximum holding force and, therefore, provides the possibility of reliable attachment of the package.

In accordance with another preferred aspect of the invention, the package further comprises an inner frame, which is located in the inner space. In this case, a permanent magnet may be located between the inner frame and the outer box. The inner frame is preferably an adjacent compartment for articles serving to accommodate tobacco products (e.g., cigarettes). In this case, the inner frame can completely cover the permanent magnet, enclosing it from the compartment for products.

Tobacco packages, such as packs of cigarettes, often contain an inner frame for holding the lid and holding the cigarettes. The frame forms a liner that can provide a thrust surface or contact surface for the lid together with the walls of the outer box. This inner frame preferably covers a permanent magnet (or magnets). In this case, the permanent magnet is not affected by the user and is not accessible either from the outside of the package or from its inside.

The inner frame may preferably extend over the entire length of the product compartment in the direction of the maximum extent of the side walls. This design of the inner frame and the outer box eliminates additional auxiliary parts (workpieces or parts thereof, etc.) designed to cover and hold the permanent magnet. This is preferable for economical packaging manufacture.

In addition, the inner frame can be made with a configuration that provides the ability to cover the lower surface of the compartment for products.

The inner frame may also be configured to cover at least the entire length of one of the side walls or front walls.

According to another preferred embodiment, the edge part of the inner frame facing the edge part of the outer box can be beveled, and the permanent magnet in this case can be fixedly attached to the edge part of the inner frame. This may be advantageous for an outer box having beveled edge portions aligned with the edge portions of the inner frame. In addition, the outer box may have rounded edge parts aligned with the beveled edge parts of the inner frame.

Attaching a permanent magnet to the outer box or to the inner frame may be preferable since the permanent magnet or magnets can / can be attached / attached to the corresponding part of the preform before fabricating (folding and assembling) the package. Since attaching a permanent magnet to a rounded edge portion may be a technically challenging task, attaching a magnet to the inner frame may be preferred.

For an outer box having a beveled edge portion, the size of said edge portion in a direction that is transverse to the direction of the maximum extent of the side walls may be smaller than the size of the beveled edge portion of the inner frame in the same transverse direction. In other words, the cut or beveled edge of the inner frame along the longitudinal edge portion of the inner frame may be narrower than the cut or beveled edge of the corresponding longitudinal edge portion of the outer box. This aspect ratio of the corresponding edge parts allows you to create a compartment for the magnet, designed to accommodate a permanent magnet between the inner frame and the outer box.

In accordance with another preferred aspect of the invention, a plurality of permanent magnets (for example, in a plurality of compartments) are located in the interior. In this case, the direction of the magnetic field of the permanent magnets may vary according to a specific pattern in accordance with aspects of the invention. For example, a plurality of permanent magnets can preferably be arranged and configured such that the external magnetic fields of the permanent magnets located in different edge parts will have different sizes and / or opposite prefixes if the magnets are located in the edge parts adjacent to the same side wall and essentially in the same place in the longitudinal direction (a place in the longitudinal direction along the edges of the packages).

In this context, the term "outer" means the direction outward from the package. In other words, the permanent magnets in the packages are preferably arranged and configured so that the poles facing the inner surface of the outer box are opposite to each other from one edge part to an adjacent edge part along the side walls (i.e., for example, along the front wall, the left wall, the rear wall and the right wall or, in other words, along the periphery (or peripheral line) of the outer box or lid) in the same or substantially the same place in the longitudinal direction. This can be done by choosing the local polarity of the permanent magnet on one edge opposite to the local polarity of the other permanent magnet in the same place in the longitudinal direction on the other (following) edge. The edges are preferably successive edges along the periphery of the outer box.

For example, the corresponding magnets are arranged so that the north pole of the magnet at the first bevel (edge part) is directed outward from the package, while at the magnet, which is located at the neighboring bevel essentially in the same place in the longitudinal direction, the south pole is directed outward packaging.

In other words, a plurality of permanent magnets can be located in the inner space, and the permanent magnets can be arranged and configured so that the permanent magnets will have opposite polarity on the surface of the permanent magnets facing outward from the outer box, if they are essentially in that the same place in the longitudinal direction and at different edge parts adjacent to the same side wall.

In accordance with one aspect of the invention, the package is configured not only to attach to magnetizable metal objects, but also to attach to other packages of the same type. In this case, a magnet or a plurality of magnets will be arranged so that they will have opposite polarity in two packages that must be connected to each other, since different or opposite magnetic fields are attracted to each other. This aspect of the invention can preferably be used to connect two packages to each other along a magnetic hinge.

In accordance with one aspect of the invention, to create a magnetic hinge between two packages, a plurality of permanent magnets (for example, in a plurality of compartments) can be located in the interior of each package in accordance with the previously described arrangement. The plurality of permanent magnets can preferably be arranged and configured such that the external magnetic fields of the permanent magnets located on different edge parts will have different sizes and / or opposite prefixes and / or opposite external polarity on the edge parts adjacent to the same side a wall and in substantially the same place in the longitudinal direction (a place in the longitudinal direction along the edges of the packages). For each package, the outer polarity of the permanent magnets on the edge parts (e.g., on the longitudinal edge parts) of the package can alternate from edge to edge along an imaginary line extending around the package (peripheral line) in the same (permanent) place in the longitudinal direction.

In an embodiment, the permanent magnets may preferably be multi-pole magnets having multiple magnetic poles. In this case, many different magnetic fields will be formed at one surface of the permanent magnet. The maximum extent of the magnetic fields is preferably the extent in the direction transverse or longitudinal with respect to the direction of the maximum extent of the walls (front, back, left, right wall) of the outer box.

Multipolar magnets, within the meaning of this term, are magnets that form opposite magnetic fields on one surface. As an example, a cuboid-shaped multi-pole magnet contains two north and two south poles on one side of the cuboid. Magnetic fields are alternately arranged, for example N / S / N / S. This is preferable when attaching two or more packages of the same type to each other, for example, to form a group or multiple packaging of packages.

To ensure magnetic attraction, the corresponding opposing magnetic fields must face each other. In the case of multi-pole magnets, there are many different positions of the two packages corresponding to this condition. Accordingly, the arrangement of the packages is very flexible. In particular, in the case of multipolar magnets having magnetic fields that extend in the longitudinal direction of the side walls, in particular along the longitudinal edges where the front and rear walls are connected to the left and right walls, there can be no significant displacement from the aligned position in the vertical direction between adjacent packages, if they meet the above condition of magnetic conformity.

The use of multipolar magnets, such as those described above, is preferable, since this may weaken the requirements for the polarity / direction of the magnetic field or the field prefix of the magnets at the edge of the packet. As discussed previously, also in the case of multi-pole magnets, a plurality of permanent magnets can preferably be arranged and configured such that the external magnetic fields of the permanent magnets located on different edge parts have different values and / or opposite prefixes (or polarity opposite the inner surface of the outer box ), if the magnets are located on the edge parts adjacent to the same side wall and essentially in the same place in the longitudinal direction (place in the longitudinal direction along the edges of the packaging c). This requirement can be slightly relaxed if multi-pole magnets with a relatively high pole density are used (a plurality of alternating poles very close to each other on the same side / surface of the magnetic strip). In this case, two packages can adhere to each other along the edges or surfaces of the packages, and the position of two or more packages relative to each other can be easily changed in a stepwise manner (i.e., for example, by the distance between alternating poles).

In accordance with one aspect of the invention, one or more permanent magnets may be located at each edge of the package. The edge portions may be longitudinal or transverse edge portions. In one embodiment, the permanent magnets can only be located on the longitudinal edge portions. These aspects of the invention make it possible to attach the package to a magnetizable surface or to another package in many different orientations.

In accordance with a preferred aspect, said at least one permanent magnet is made of magnetic material containing rare earth elements.

At least one permanent magnet may comprise neodymium (Nd), iron (Fe), and boron (B). The addition of rare earth elements makes it possible to obtain solid magnetic material having a high residual magnetization.

At least one permanent magnet preferably contains a coating of preferably nickel (Ni), copper (Cu) and / or gold (Au), which prevents the oxidation of the magnetic material.

The permanent magnet preferably creates a holding force of at least 350 g / cm ² .

At least one permanent magnet may have a residual magnetic induction of 300 mT to 900 mT.

The residual magnetic induction may preferably be from 500 mT to 650 mT.

In an embodiment, the residual magnetic induction may preferably be from 570 mT to 600 mT.

It has been found that magnetic holding force in the above ranges provides reliable and secure fastening of the appropriate packaging to almost any metal household item.

In accordance with another aspect of the invention, a multiple package is provided comprising multiple packages in accordance with one of the aforementioned aspects of the invention.

In accordance with one aspect of the invention, a magnetic hinge is formed between adjacent packages, for example packs of cigarettes, the packages preferably being arranged so that they form a booklet having a magnetic hinge. The magnetic hinge preferably allows the formation of a booklet for smoking articles, which is very flexible. Packages of various types, even designed for different smoking articles, can be fastened so that a booklet is formed. Single packages are interchangeable, for example, smoking products of a different type or with a different flavor can be added to the booklet or replaced in the booklet. The magnetic hinge allows two respective packages to rotate relative to each other around the magnetic hinge. However, unlike other hinges formed from fold lines in cardboard, the magnetic hinge can be easily disconnected and reconnected. The use of multi-pole permanent magnets may be preferred to form a magnetic hinge between the two packages.

In accordance with another aspect of the invention, a blank has been developed for the manufacture of packaging for tobacco products in accordance with the above aspects. The package to be formed from the workpiece has an outer box containing a bottom wall and additional side walls (front, back, left, right), extending from the bottom wall. In addition, the outer box contains an inner space and has an opening opposite to the bottom wall or side wall. The adjacent side walls of the outer box are formed during manufacture by bending the workpiece along a fold line extending in the direction (for example, the maximum extent) of the side walls, wherein said at least one permanent magnet is fixedly attached to the (inner) surface of the workpiece, so that the permanent magnet will located inside the package to be formed from the workpiece.

The preform is preferable because the attachment of permanent magnets to the preform, that is, before the manufacture of the package, is much simpler from a technical point of view in comparison with the attachment of magnets to the package itself.

The preform preferably comprises a part of the workpiece, which is configured to provide the creation of the inner frame, and a part of the workpiece, which is configured to provide the creation of the outer frame. In this case, the packaging for tobacco products can be made from the workpiece by bending the corresponding parts of the workpiece along an additional fold line extending in the longitudinal direction of the maximum length of the side walls (front, back, left, right wall) to place at least one permanent magnet between outer and inner frames.

The implementation of the parts of the workpiece for the outer box and the inner frame in this way provides the ability to place permanent magnets between the outer box and the inner frame. Packaging for smoking articles can preferably be made from one single piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Figure 1 presents a simplified perspective view of a packaging 2 for tobacco products, preferably a cigarette pack, in accordance with one embodiment of the invention. The package 2 contains an outer box 3 having four side walls 4, which are connected by means of the respective edge parts. According to an embodiment, the edge parts are chamfers 6, however, the edge parts can also be rounded. The side walls 4-1 (front wall), 4-2 (right wall), (4-3 (rear wall) and 4-4 (left wall), as well as the bottom wall 10 are not shown) and chamfers 6 continue in the vertical direction from the lower wall 10 (not shown) and form a hole that is closed by a cover 5 containing the upper wall 8 and the front wall 4-5, the rear wall 4-7 (not shown) and two side walls 4-6 and 4-8 (not shown). The corresponding walls 4-5, 4-6, 4-7 and 4-8 and the chamfers 6 of the cover also extend from the upper wall 8. In this embodiment, two permanent magnets (invisible) on the chamfer 6 are located in the inner space, which is surrounded by an outer box 3. The position of the permanent magnets is shown by means of the respective magnetic zones 9. The magnets are attached to the inner surface or are located adjacent to the inner surface of the outer box 3.

Figure 2 is a simplified front view of the packaging of Figure 1. The front wall 4-1 of the outer box and the chamfers 6 extend from the lower wall 10 in the longitudinal direction Y. The position of the permanent magnets, which are located on the inner surface of the chamfers 6, is also indicated by a dashed line showing the corresponding magnetic zones 9.

FIG. 3 is a simplified side view of the package 2, known from FIGS. 1 and 2. The side wall 4-2 extending from the bottom wall 10 and the corresponding chamfers 6 extend in the longitudinal direction Y, which is the direction of the maximum extent of the side walls 4 (see also FIG. 2). The position of the two permanent magnets on the chamfer 6 is also indicated by dashed lines showing the corresponding magnetic zones 9.

Figure 4 is a simplified top view of the package 2, in section IV-IV in Figure 2. The outer box 3 contains four side walls 4-1, 4-2, 4-3 and 4-4 and corresponding chamfers 6, which are located in the edge of the package 2 between adjacent / adjacent side walls 4-1 and 4-2, 4- 2 and 4-3, 4-3 and 4-4 and 4-4 and 4-1. The outer box 3 surrounds the inner space 14. The inner frame 15, containing the inner chamfers 18 and the inner side walls, is located in the inner space 14. Permanent magnets are located in the inner space of the outer box, and the permanent magnets can be arranged and made so that the permanent magnets will have opposite polarity on the surface of the permanent magnets facing outward from the outer box, if they are in essentially the same place in the longitudinal direction enii (Y) and at different edge portions adjacent to the same side wall. The section line is a section through the outer packaging box (walls 4-1 - 4-4 and beveled edges 6-1 - 6-4 between adjacent walls 4-1 - 4-4) in some place in the longitudinal direction Y. Polarity of permanent magnets on the surface facing outward from the package, in this case it can change from edge 6-1 (for example, the north pole) to the next edge 6-2 (south pole), to the next edge 6-3 (north pole) to the last edge 6-4 (south pole). The cross section defines the periphery in a constant place in the longitudinal direction Y along the walls and edges in accordance with the following order 4-1, 6-1, 4-2, 6-2, 4-3, 6-3, 4-4 and 6- four. Edge 6-1 is located between adjacent walls 4-1 and 4-2. Edge 6-2 is located between adjacent walls 4-2 and 4-3. Edge 6-3 is between the walls 4-3 and 4-4, and edge 6-4 is between the adjacent walls 4-4 and 4-1. The same idea can be used if the magnets are located in the lid of the package. Following the periphery at a constant level in the longitudinal direction ensures that the external polarity of the magnets at this level will alternate from edge to edge.

A detailed view of the edge of the package 2 is presented in Figure 5. The inner chamfers 18 have a DIF length in a direction that is transverse to the Y direction of the maximum length of the side walls 4-2 and 4-3 (see Figure 2 or 3), while the DIF length is greater than the corresponding DOB size of the chamfer 6-2 (that the same idea can be used for all the edges 6-1 - 6-4 shown in Fig. 4) of the outer box 3. Between the inner chamfer 18 of the inner frame 15 and the chamfer 6-2 of the outer box 3 there is a magnet compartment 20 containing a permanent magnet 22. According to an embodiment, the permanent magnet 22 can T represents a top magnet of the pair of permanent magnets which is positioned at each of the chamfers 6 (or 6-1 - 6-4) in the edge of the package 2 (see also Figures 1-4.). The permanent magnet 22 is fixedly mounted in the magnet compartment 20, for example by gluing the permanent magnet 22 in the corresponding magnet compartment. The permanent magnet is preferably fixedly attached to the outer box 3. This can be done, for example, by means of a suitable adhesive tape.

In accordance with further embodiments, the permanent magnet 22 may have a self-adhesive strip attached to the magnetic material. Even self-adhesive magnetic paste can be used. The permanent magnet may be in the form of a cuboid, but other forms of the magnet, for example, dots, may be suitable.

6 is a simplified perspective view of a tobacco packaging 2 in accordance with another embodiment of the invention. A package, which is preferably a cigarette package, is similar to package 2 of FIG. 1. However, the package 2 of the embodiment shown in FIG. 6 contains one magnet per chamfer 6. The position of the magnets is also indicated by dashed lines showing the corresponding magnetic zones 9. By way of example only, the permanent magnet on the right can be positioned so that its magnetic north pole will be directed outward from the package, as shown by the letter “N” in magnetic zone 9. The magnet, which is located in the magnetic zone on the left, is opposite because its magnetic south pole is directed outward from the package 2.

FIG. 7 is a corresponding simplified front view of the package of FIG. 6, and FIG. 8 is a corresponding simplified side view of a package 2 for smoking articles known from FIGS. 6 and 7.

FIG. 9 is a plan view of a blank 24 for manufacturing a packaging for tobacco products, in accordance with aspects of the invention. The package 2 in accordance with the embodiments of FIGS. 1-5 can be made from a blank 24. The blank 24 comprises a first blank part 26, which is configured to form an outer box 3. Between the side walls 4-1, 4-2 , 4-3 and 4-4 there are zones made with a configuration that ensures the formation of chamfers 6, and permanent magnets 22 are attached to the corresponding zones of the chamfers. Chamfers 6, which are adjacent to each other with respect to the same side wall 4-1, 4-2, 4-3 or 4-4, contain permanent magnets 22 having a magnetic field with opposite prefixes. In accordance with the embodiment of FIG. 6, the outer left chamfer 6 (between walls 4-2 and 4-1) contains permanent magnets 22 having a north pole N directed upward, that is, towards the viewer, and the next chamfer 6 on the right (between the walls 4-1 and 4-4) has magnetic south poles S, which are directed upwards. The permanent magnets 22 are preferably cuboidal bodies having one magnetic pole on each of their side surfaces.

However, multi-pole magnets can also be used. 10 and 11 show multipolar magnets with a cuboid shape. 10, the magnetic poles “N” and “S” “continue” in the Y direction of the maximum extent of the respective lateral zones 4 of the packet (see FIGS. 2 and 3). In contrast, in FIG. 11, the magnetic poles of the permanent magnet 22 are perpendicular to the Y direction.

The blank 24 of FIG. 9 contains a blank part 28, which is intended for the manufacture of the inner frame 15. This blank part 28 contains bevels 18 having a length DIF in the X direction, which is transverse to the direction Y of the maximum length of the side walls 4, while the length DIF larger than the corresponding DOB size of the chamfers 6 of that part 26 of the workpiece that is intended for the outer box 3. By bending that part 28 of the workpiece that is intended for the inner frame along the fold line 30 over that part 26 beyond otovki which is intended for the outer box 3, compartments are formed in the manufacture of magnets between bevels 6 of the outer box 3 and the chamfers 18 of the inner frame 15. The packing may preferably be made from a single blank 24.

12 is a top view of the inner surface of a blank 30 for manufacturing an outer box 3 having a lid 5 pivotally connected to one of the side walls 4-3 (rear wall), in accordance with another embodiment of the invention. The blank 30 contains 2 permanent magnets 22 on the chamfer 6, while the direction of the magnetic field of the permanent magnets 22 of one chamfer 6 is opposite to the direction of the magnetic field of the permanent magnets of the adjacent chamfer along the walls 4-1, 4-2, 4-3 and 4- four.

An additional blank 32 for manufacturing the inner frame is shown in a plan view of its outer surface in FIG. 13. The blank 32 for the inner frame is preferably glued to the blank 30 for the outer box (see FIG. 12) for the manufacture of a tobacco packaging 2.

The length of the DIF for the manufacture of inner chamfers 18 of the inner frame 15 is greater than the corresponding size of the DOB chamfers 6 of the workpiece 30, which is intended for the manufacture of the outer box 3.

Permanent magnets 22, which are preferably made of a magnetic material containing rare earth elements, such as neodymium (Nd), iron (Fe) and boron (B), have a coating or galvanic coating formed of nickel (Ni), copper (Cu) and / or gold (Au) to inhibit the oxidation of magnetic material.

The permanent magnet creates a holding force F of at least 350 g / cm ² . The holding force F is determined in accordance with the usual technical standards, while the magnetic holding force F can be determined by the expression:

F = (B ² / 2µ ₀ ) ∗ A,

where B is the flux of the magnetic induction vector, μ ₀ is the magnetic constant of the field in vacuum, and A is the surface area of the permanent magnet. The surface area A is the area of the corresponding surface of the permanent magnet that faces the object to which the package is attached. In accordance with the embodiments of FIGS. 1-3 and FIGS. 6-8, it is the sum of the areas of the magnetic zones 9 for the corresponding chamfer. In other words, the holding force for the package 2, which is attached to the corresponding third item, such as an iron frame, etc., can be determined from the force of the magnetic zone 9 on the chamfer (as a result of area A in accordance with the above formula) and flow B the magnetic induction vector of the permanent magnet 22 at an appropriate distance between the permanent magnet 22 and the object to which the package 2 is attached. As a rule, this distance is determined by the thickness of the chamfer 6 of the outer box 3.

The flux B of the magnetic induction vector is determined by the residual magnetic induction of the permanent magnet 22, which is from 300 mT to 900 mT, preferably from 500 mT to 650 mT, and more preferably from 570 mT to 600 mT.

Although the invention has been described above with reference to certain embodiments, it is not limited to these embodiments, and additional alternatives within the scope of the claimed invention will be apparent to those skilled in the art.
