Description

The invention relates to a packaging system.

Such a packaging system is generally used to package goods.

From the DE 10 2015 120 783 A1 a packaging system is known which has at least one flat or shell-shaped base element and at least one tarpaulin made of flexible material which can be connected or connected to the base element and is hood-shaped in the unfolded state and has at least one tarpaulin opening which can be put over or put over the base element, the packaged goods being in a closed state Packaging system is enclosed by the floor element and the tarpaulin. The tarpaulin has a tarpaulin seam running around the tarpaulin opening and in which at least one tether runs. The floor element has a counter-support for the side edge forming a retaining rope. The tether is coupled to a hand-operated or motor-operated rope tensioning device.

To provide a security system, the tarpaulin is at least partially made of a textile material, in or onto which at least one electrical conductor structure is incorporated or applied using textile technology, the conductor structure being coupled to at least one alarm device, so that in the event of at least partial destruction of the textile material Closure state as a result of a short circuit between at least two conductors of the conductor structure and / or destruction of at least one conductor of the conductor structure, an alarm signal is triggered by the alarm device.

The assembly of such a packaging system is relatively complex. The design effort of the packaging system is also complex, and it is particularly disadvantageous that the closure mechanism for closing the packaging system requires a lot of design effort.

The DE 44 31 046 A1 relates to a packaging container that can be used to hold filling goods as a self-supporting container or as an in-liner or setting container in load-bearing outer containers such as corrugated cardboard boxes, wooden crates, mesh box pallets or barrels. The packaging container contains a multi-layer composite film combination, which is made up of a polymer film with barrier layer properties that acts as the outer layer of the container, an intermediate layer made of an electrically conductive material and a further polymer film that forms the inner layer of the packaging container. The further polymer film forming the inner layer of the packaging container has a perforation pattern and the electrically conductive intermediate layer is connected to a grounding system via electrical contact points. The polymer film forming the inner layer of the packaging container is preferably a heat-sealable monofilm or a coextruded film.

The DE 93 11 620 U1 relates to a leak-testable rubber-based lining. The lining contains an electrically conductive rubber layer.

The invention is based on the object of providing a packaging system which has a high level of functionality with little design effort.

The features of claim 1 are provided to solve this problem. Advantageous embodiments and useful developments of the invention are described in the dependent claims.

The invention relates to a packaging system which is designed in the form of a box. The packaging system has a security system with electrically conductive structures forming sensor structures which extend over walls of the box. The walls each have inner walls and outer walls, between which a carrier material with the electrically conductive structure is arranged. The carrier materials as well as the inner walls and the outer walls are glued or welded together, in the latter case, at least in the area of welds, the carrier material on the one hand and the inner walls and outer walls on the other hand consist of similar materials.

An essential aspect of the invention is to provide the packaging system in the form of a box. The term box generally includes box-shaped structures with dimensionally stable walls.

The box can be designed in different sizes depending on the type of packaged goods to be stored in it.

One advantage of this packaging system is that the dimensionally stable walls ensure that the packaged goods are stored in the box protected against damage.

An essential aspect of the invention is that the electrically conductive structures are integrated into the walls of the box as components of a security system.

The security system generally implements security functions, which increases the functionality of the packaging system.

According to the invention, the walls of the box each have an inner wall and an outer wall made of a non-conductive plastic, with a carrier material with electrically conductive structures being arranged between the inner wall and the outer wall.

The electrically conductive structures and thus the carrier materials advantageously extend over the entire surfaces of the walls of the box.

To connect the carrier material to the respective inner wall and outer wall, the carrier material is welded to it. It is essential that the inner wall and outer wall on the one hand and the carrier material on the other hand consist of similar, preferably identical materials so that durable, stable welded connections are formed between these units. Similar plastics have the same or almost the same flow or temperature properties. Similar materials can be derivatives of a plastic. The outer walls, inner walls and carrier materials can also consist of plastics that only differ from one another in terms of doping and admixtures, but consist of the same base material. Particularly suitable plastics for forming the inner walls, outer walls and the carrier material are polypropylene and polyethylene.

In principle, the carrier material can only be welded to the inner wall and outer wall at individual discrete locations, so that it is sufficient that the materials of the inner wall, the outer wall and the carrier material only match there.

Particularly advantageously, the carrier material as well as the inner walls and outer walls consist of identical or similar materials over their entire surfaces.

In this case, the carrier material can be welded to the inner and outer walls at any point. Furthermore, the carrier material can also be welded over the entire surfaces of the inner and outer walls. Such full-surface welding results in a particularly stable bond.

In general, by welding the inner walls, outer walls and the carrier materials, a mechanically stable yet lightweight wall construction of the box can be achieved. The welding processes leave the mechanical properties of the inner walls, outer walls and the carrier materials largely unchanged, i.e. their mechanical properties are not affected.

According to a particularly advantageous embodiment of the invention, the carrier material as well as the inner walls and outer walls consist of identical materials.

The stabilization grid can be made, for example, by punching out a film or plate, which preferably consists of the same non-conductive plastic as the carrier material of the electrically conductive structure and the inner wall.

The stabilization grid can then be welded to the carrier material of the electrically conductive structure as well as the inner wall or outer wall.

The stabilization grid gives the wall construction the required mechanical stability, in particular high dimensional stability, it being further advantageous that the inner wall and the outer wall can have small wall thicknesses.

According to a further advantageous embodiment of the invention, the outer walls form an electromagnetic shield.

The outer walls then form a full-surface electrically conductive structure, which provides effective EMC protection for the internal electrically conductive structures and any electronic units that may be arranged in the box. In addition, the outer walls designed in this way provide protection against manipulation, since the electrically conductive structures and electronic units arranged in the interior of the box are protected against radiation from electromagnetic interference signals.

According to a first variant, each outer wall consists of an electrically non-conductive plastic, which is doped over the entire surface with electrically conductive particles.

This means that the entire outer wall forms an electromagnetic shield.

In this case, a stabilization grid is mandatory as electrical insulation between the outer wall and the electrically conductive structure.

According to a second variant, the outside of each outer wall is coated over the entire surface with an electrically conductive layer.

In this case, the outer wall consists entirely of an electrically insulating material.

The electrically conductive structures preferably consist of metallic materials, but this is not mandatory. In principle, electrically conductive ceramics, glasses, plastics and the like can also be used.

In principle, the carrier material can be a film or the carrier material can be plate-shaped.

In this case, the electrically conductive structures are advantageously applied to the carrier material by coating, printing, embroidery, vapor deposition or spraying.

According to a particularly advantageous embodiment, the carrier material is a textile surface.

The textile surface can be designed as a woven, knitted, knitted or non-woven fabric.

In this case, the electrically conductive structures are formed by electrically conductive threads incorporated into the textile surface.

If the textile surface is designed as a woven, knitted or knitted fabric, the conductive threads forming the electrically conductive structures can preferably be incorporated during the manufacturing process of the textile surface.

According to the invention, the electrically conductive structures form sensor structures.

The electrically conductive structures extend over the entire surface of the box walls.

Furthermore, control units are assigned to the sensor structures, by means of which interruptions in the electrically conductive structures can be detected.

The electrically conductive structures advantageously form a close-meshed grid structure that extends over the entire wall structure of the box. This means that even small local interruptions at any position on the wall structure lead to a reliably detectable signal that can be evaluated in the control units. If an interruption is detected, the alarm device, which is connected to the control units, generates an alarm message, with this alarm message reporting the interruption of the electrically conductive structures or an unauthorized opening of the box as unauthorized manipulative intervention in the box. The alarm device can have an optical and/or acoustic signal generator arranged on the box. The control units can be formed, for example, by RFID units, that is, RFID readers, RFID transmitters and RFID receivers.

For this purpose, the objects stored in the box are advantageously marked with RFID tags, which are recorded with an RFID reader. The alarm device can then evaluate whether the box has been filled correctly with objects or whether objects have been stolen. Depending on this, a status signal can be generated in the alarm device that indicates the current loading status. Furthermore, an alarm message can be generated if there is incorrect assignment of objects.

This functionality can be further expanded by associating a GPS tracker with the alarm device.

With the GPS tracker, it is possible to continuously locate the packaged goods in the box. This information can be integrated into the status signals.

According to an advantageous embodiment, the alarm device has an interface for exchanging data with an external unit.

In particular, the interface provides access to the Internet.

Status signals and alarm messages can be output via the interface and can thus be tracked by third parties from an external unit.

1 shows schematically an exemplary embodiment of a box 1, which forms a packaging system. In the present case, the box 1 is cuboid and is made of plastic.

The box 1 has a base body 2, which includes a base part 3 and side walls 4 mounted on it. The side walls 4 and the base part 3 enclose a cavity which forms the loading space of the box 1.

The upper edges of the side walls 4 define an opening through which the interior of the box 1 can be loaded. This opening can be locked with a lid 5 as a further component 3 of the box 1.

Box 1 forms a modular unit. How 2 shows, the side walls 4 of the box 1 can be folded together and inserted into the trough-shaped base part 3. The unit formed in this way can be closed with the lid 5 ( 3 ). In this form, the empty box 1 can be easily transported as a compact unit.

In the assembled state of box 1, which is in 1 is shown, the lid 5 is placed on the base body 2 in particular after loading the interior of the box 1. The cover 5 is secured in position on the base body 2 with two locking means in the form of locking bolts 6 on opposite sides of the cover 5 ( 3 ). The closure means can generally also be designed as latches, locking means and the like.

Furthermore, the box 1 can be locked with four security locks 7. Two security locks 7 are located on opposite sides of the lid 5. Each security lock 7 is secured with a code, which means it can only be opened by entering the code. A suitable input unit such as a keypad or a keyboard can be provided for code entry. Furthermore, the code can generally also be entered via non-contact data interfaces such as Bluetooth interfaces and the like.

According to the invention, the box 1 and thus the packaging system has a security system with which the box 1 is secured against manipulation and in particular unauthorized intervention.

Electrically conductive structures 8 are provided as components of the security system and extend over the entire surface of all walls, i.e. side walls 4, the lid 5 and the bottom part 3 of the box 1.

How 4 shows, the electrically conductive structures 8 in the present case are formed by electrically conductive threads which are incorporated into the carrier material 9 of a textile surface 10 made of non-conductive material.

In the present case, the textile surface 10 consists of a knitted fabric that is produced, for example, with a warp knitting machine or a Raschel machine. The carrier material 9 forms a matrix of non-conductive threads made of plastic, for example polypropylene. During the manufacturing process of the textile surface 10, which is in this matrix 4 lattice structure shown is incorporated by electrically conductive threads, which forms the electrically conductive structure 8. The electrically conductive threads consist of a metallic material, in particular stainless steel.

Alternatively, the textile surface 10 can consist of a woven, knitted or knitted fabric.

Furthermore, the carrier material 9 can consist of a film or plate made of plastic, in which case the electrically conductive structure 8 is applied to the carrier material 9 by coating, printing, vapor deposition or spraying.

5 shows the wall construction of the box 1 according to the invention, this wall construction extending over the entire surfaces of the box 1.

How out 5 can be seen, is the textile surface 10 with the carrier material 9 and the electrically conductive structures 8 according to 4 formed between an inner wall 11a and outer wall 11b as a wall element of the corresponding wall. There is a stabilization grid 11c between the outer wall 11b and the electrically conductive structures 8. The carrier material 9 with the electrically conductive structures 8 and the stabilization grid 11c extend over the entire surfaces of the inner walls 11a or outer walls 11b, which have the same area and consist of thin plates made of plastic.

The inner walls 11a, the outer walls 11b and the stabilizing grids 11c consist of the same plastic, this plastic being at least similar, preferably identical, to the plastic of the carrier material 9 of the textile surface 10. In the present case, the carrier material 9, the inner walls 11a and the outer walls 11b consist of polypropylene or polyethylene.

The outer walls are doped over the entire surface with electrically conductive particles and thus provide EMC protection and protection against manipulation for the electrically conductive structures and electronic units arranged in the box. Alternatively, the outside of each exterior wall may be coated with an electrically conductive layer. In this case, the outer wall consists entirely of a non-conductive plastic.

According to the invention, the inner walls 11a, the carrier material 9 and the outer walls 11b are welded together. This is possible because these units are made of the same (or at least similar) plastic. The welding can take place over the entire surfaces of the inner walls 11a and outer walls 11b, whereby a stable connection of these units is obtained without affecting the mechanical properties of these individual units. Of course, these units can also only be welded together locally.

6 shows a block diagram of the components of the security system according to the invention. The security system includes an alarm device 12, which has a computer unit, not shown. A GPS tracker 13 is assigned to the alarm device 12. Furthermore, the alarm device 12 is assigned an interface 14 for connection to an external unit. In the present case, the interface 14 is designed as an Internet interface. Finally, the security lock(s) 7 and a signal generator 15, which can be designed as an optical or acoustic signal generator 15, are connected to the alarm device 12. Finally, at least one RFID unit 16 is connected to the alarm device 12, which forms a control unit to which the electrically conductive structures 8 are connected. Instead of RFID units, other inductive or capacitive units can also be provided.

The GPS tracker 13 can be used to track objects loaded in the box 1. Together with the signals generated by the RFID unit 16 for detecting objects, spatially resolved status signals about the current loading status are generated in the alarm device 12, which are read out via the interface 14. This allows a user, in particular the supplier of the objects stored in box 1, to precisely track the objects stored in box 1.

The closed status of the security lock(s) 7 can be transmitted as a further status message.

Finally, an alarm message is generated in the alarm device 12 if an interruption in the conductive structure 8 of the box 1 is registered with the RFID unit 16. A further alarm message can be generated if the RFID unit 16 registers that objects are missing in the box 1. These alarm messages can be output via interface 14. In addition, these are displayed locally on the box 1 with the signal generator 15 controlled by the alarm device 12.

Finally, an alarm message can be generated if the box 1 is tampered with by covering it with a conductive film or the like, so that data exchange via the interface 14 is prevented over a longer period of time.

The interface 14 assigned to the alarm device 12 can also be used by a user, in particular the supplier of the packaged goods, to query status parameters of the security system.

Furthermore, the supplier can give the customer a release for access to the packaged goods via the interface 14 as soon as the customer has received the packaged goods. In the simplest case, the supplier sends the customer the code with which he can open the security lock 7.

The customer can then enter the code on the security lock 7 using an input unit such as a keyboard or via a non-contact interface 14 such as a Bluetooth interface and open the security lock 7. In principle, the security lock 7 can be opened directly via the interface 14 assigned to the alarm device 12 using suitable release commands.
