Description

[0001] The field of the invention is that of logistics. More specifically, the invention relates to the field of design and manufacture of secure packages and to the field of design and manufacture of tracking systems allowing the condition of such packages to be checked.

[0002] The invention more particularly relates to packages provided with seals.

[0003] Packages are used to transport objects within a supply chain. Typically, a package is a container that defines a cavity in which one or more objects are to be positioned during transport.

[0004] The package further comprises means for closing the package to prevent access to the cavity.

[0005] For example, the package may be formed by a box defining the cavity and by a cover movably or removably mounted on the box or by one or more flaps belonging to the box itself. Boxes or paperboard are usually used to form such packages.

[0006] According to another example, the package may be formed by a flexible bag, for example plasticized, defining a cavity for containing the object(s). In this case, the closing means may be formed by an adhesive film adhered to the bag, which is previously folded upon itself to close an opening allowing access to the cavity. The closing means may also consist of an excess portion of the material forming the bag and is intended to be folded over the opening and then adhered to the flexible bag.

[0007] Often, it is important to be able to control and / or secure the contents of a package.

[0008] For this reason, a safety device may be used on the packaging. In particular, a seal may be fixed to the packaging to verify that they have not been opened.

[0009] A seal is generally a device that is fixed to the object to be protected (eg a document, a package, a room...) in such a way that it is impossible to open the object without breaking and damaging the seal.

[0010] The seal may consist of a single impression to which a seal is impressed, such as a wax seal protecting an authentic document, or a lead seal protecting a water or energy meter.

[0011] According to another example of a seal, plastic seals are known which allow to ensure that a mail bag, a container or a metal box is kept in a closed configuration. These seals are generally made of plastic material and comprise a body and a connecting piece extending from the body. The connecting piece is relatively flexible and is used to form a buckle which is then engaged in a complementary opening of the body. The opening and the connecting piece are designed so that the connecting piece is irreversibly inserted into the opening and only the degradation of the seal, which in turn is irreversible, allows the buckle to be opened.

[0012] Thus, according to conventional designs, the seal includes a portion that is irreversibly degradable when the article to which the seal is attached is opened.

[0013] Such seals are particularly easy to manufacture and implement. However, they do not allow accurate, real-time knowledge of when an object has been opened, or of the state of the seal without direct visual inspection on site, which is sometimes or often impossible.

[0014] In the field of the present invention, it is also known to use labels on wine bottles that incorporate a unique identifier, such as an alphanumeric reference, a barcode or a radio frequency identification device (RFID).

[0015] These electronic tags allow consumers to access information inherent to the bottle that has been pre-recorded in a database.

[0016] An RFID device specifically comprises a radio identification electronic chip coupled to an antenna.

[0017] In order to obtain the information contained in the electronic chip, a transceiver complementary to the antenna and the electronic chip must be used. This transceiver is designed to transmit a request by radio (which is intended to be picked up by the antenna and sent to the electronic chip) and then receive a response generated by the electronic chip and sent by the antenna.

[0018] This label therefore allows the bottles to be labeled in order to ensure tracking of the wines and facilitates stocking without the need to handle the bottles. For the consumer, he can access the detailed product list via his smartphone by means of a code (QR code) displayed directly on the label.

[0019] In practice, these RFID tags are implemented to meet the expectations of the wine industry, namely, wine anti-counterfeiting and product tracking.

[0020] However, these specific means are not provided for ensuring that the package or packaging has not been opened.

[0021] The object of the invention is, inter alia, to overcome the disadvantages of the prior art.

[0022] More specifically, an object of the present invention is to provide a security package using a seal which allows knowing in real time whether the seal has been broken.

[0023] This object and other objects that arise subsequently are achieved by the present invention, which relates to a package comprising:

[0024] - a container having a cavity;

[0025] - closure means capable of adopting, together with the container, a closed configuration in which it prevents access to the cavity, or an open configuration in which it allows access to the cavity;

[0026] - a seal which ensures that the package remains in its closed configuration;

[0027] Wherein, the sealing element comprises:

[0028] - a portion that is irreversibly destructible when said package is switched from said closed configuration to said open configuration;

[0029] - Radio identification electronic chip;

[0030] - a first communication device comprising an antenna, said first communication device being coupled to said electronic chip and extending at least partially into said destructible portion of said seal;

[0031] Characterized in that the packaging is combined with an electronic unit separated from the sealing member, and the electronic unit comprises:

[0032] - a transceiver configured to periodically send radio requests that can be picked up by the antenna and then transmitted to the electronic chip, and to receive return signals generated by the electronic chip in response to the radio requests and then transmitted by the antenna, the electronic unit being configured to detect the absence of a return signal;

[0033] - A second communication device configured to transmit an alarm signal directed to a remote receiver in the absence of a return signal.

[0034] Due to the package according to the present invention, it is possible to know in real time whether the seal which ensures that the package remains in a closed configuration has been destroyed. Therefore, this information allows knowing that after attaching the seal or its initialization, the package is opened for the first time.

[0035] Consultation of a remote electronic package tracking unit provides real-time insight into this information.

[0036] Indeed, opening the package, and in other words switching from its closed configuration to its open configuration, results in the destruction (rupture) of the destructible portion of the seal.

[0037] Since the first communication means are partially integrated into the destructible part, they are also destroyed when the package is opened.

[0038] This destruction of the first communication means then prevents the transceiver from receiving and / or sending requests to the radio identification electronic chip, and this electronic chip does not generate a return signal.

[0039] More generally, the destruction of the first communication means ultimately renders ineffective the radio identification assembly formed by these first communication means and the radio identification electronic chip.

[0040] According to an advantageous characteristic, said first communication means further comprises at least one breakable electrical conductor coupling said antenna to a radio identification electronic chip, said breakable electrical conductor(s) passing through said destructible portion of said seal.

[0041] In this case, during the destruction of the seal, the breakable electrical conductor(s) are broken. Thus, the destruction of the seal results in the separation of the wireless identification electronic chip from the antenna by the destruction of the breakable electrical conductors.

[0042] This solution is easy to implement since only the breakable electrical conductor(s) have to pass through the destructible portion of the seal.

[0043] According to a preferred design, each of the container and the closure device has a member for receiving the seal, the two receiving members being in close proximity to each other in the closed configuration of the package.

[0044] And the seal takes the shape of a collar for coupling to each of the receiving members in a closed configuration of the package.

[0045] This design makes it particularly easy to realize the package according to the invention and its seal.

[0046] In practice, all the user has to do is to close the package and then attach the seal to the two receiving members to install the seal.

[0047] For example, the two receiving members may each be annular in shape, into which the collar is inserted to form an inviolable buckle.

[0048] The two receiving elements can also each have a hook shape, wherein the hook shape prevents the seal from being removed without destruction, wherein the collar must be snugly fastened on the two hooks.

[0049] According to a particular embodiment, the collar comprises:

[0050] - a head carrying a cage;

[0051] - A strip made of flexible material extending from the head and complementary to the insertion of the retainer, said strip forming the destructible portion of the seal.

[0052] The collar thus has a shape that is easy and cheap to implement.

[0053] In this case, advantageously, the strip extends from said head to a free end, said breakable electrical conductor(s) extending along the strip between said head and said free end.

[0054] This design allows the collar to form a larger or smaller buckle depending on how deep the strap is inserted into the cage.

[0055] In fact, since the electrical conductor(s) extend along the strip between the head and the free end, the strip can be cut at any position between the head and the free end of the strip while producing the desired decoupling effect between the radio identification electronic chip and the antenna.

[0056] More specifically, according to an advantageous feature, said radio identification electronic chip is housed in the free end of said strip and said antenna of said first communication means is housed in the head of the loop.

[0057] This embodiment is particularly easy to implement and allows the collar to be rendered non-specific with respect to the implementation of the radio identification tag.

[0058] More specifically, a person who is not familiar with the packaging according to the invention is even less likely to recognize said seal comprising a radio identification electronic chip as a seal different from other conventional seals not comprising such radio identification means.

[0059] According to a more specific design, the collar is a self-locking clamp and the cage is a non-return cage.

[0060] A self-locking clamp of this type offers particularly advantageous simplicity of implementation.

[0061] In fact, in conventional manner, the user only has to insert the strip into the non-return cage so as to effectively lock the strip directly in the cage.

[0062] According to an advantageous solution, the electronic unit is housed in a wall or a bottom of the container or in a cover of the container.

[0063] Therefore, the electronic unit cannot be detected from inside the container.

[0064] The electronic unit is then hidden and contributes to the undetectable nature of the seal's sealing ability to send an alarm when the seal is breached.

[0065] Advantageously, said electronic unit comprises means for time-stamping said alarm signal.

[0066] In this way, the alarm signal comprises data relating to the time of breach of the seal and the opening of the package.

[0067] This allows the user to record exactly when the seal is broken.

[0068] The present invention also relates to a tracking system, comprising:

[0069] - at least one package according to any one of the preceding claims, the seal of which comprises an initial identification code written into the radio identification electronic chip;

[0070] - a computer server incorporating said remote receiver, said computer server comprising a database listing authenticated identification codes and configured to identify said initial identification code of said seal in said database.

[0071] This tracking system allows ensuring that an electronic trace of the state of the seal is created.

[0072] According to this design, only seals previously known in the database will work.

[0073] The present invention also relates to a method for tracking a package of the above tracking system, the method comprising:

[0074] - a step of transmitting, by said transceiver, a radio request in the direction of said seal, said radio request being able to be picked up by said antenna and then transmitted to said electronic chip;

[0075] - A step of waiting for reception of a return signal generated by said electronic chip in response to said radio request;

[0076] And in the event that no return signal is received, the step of waiting for receipt of the return signal is followed by the step of broadcasting an alarm signal to a remote receiver.

[0077] Advantageously, before the step of transmitting the radio request, the method comprises a sequence of pairing the seal with the package, the pairing sequence comprising successively:

[0078] - a step of reading the initial identification code of the seal by the transceiver;

[0079] - a step of sending said initial identification code by said transceiver to said computer server;

[0080] - a step of identifying said initial identification code by said computer server;

[0081] - A step of generating a new unique identification code by the computer server and sending the new unique identification code to the transceiver;

[0082] - A step of sending said new identification code by said transceiver and writing it into said seal.

[0083] According to the method, a new identification code generated and authenticated by a computer server is written into the wireless identification electronic chip of the seal.

[0084] Thus, once it is used to protect a package, the seal benefits from the new identification being properly listed in the system.

[0085] Advantageously, the pairing sequence ends with a test by the transceiver for the presence of a seal on the package.

[0086] Preferably, the identification step includes the step of comparing the initial identification code with authenticated identification codes of the database to authenticate the seal and authorize the generation of a new unique identification code.

[0087] Thus, during the pairing sequence, the seal is either authorized or rejected.

[0088] Other features and advantages of the present invention will become more apparent from the following description of preferred embodiments of the present invention and the accompanying drawings, in which preferred embodiments of the present invention are given by way of illustrative and non-limiting examples, in which:

[0089] Figure 1 is a schematic diagram of a package according to the present invention, which shows the package in a closed configuration and provided with at least one seal;

[0090] Figure 2 is a schematic diagram showing more particularly a seal attached to a package according to the present invention, the seal being more particularly coupled to two package receiving members;

[0091] Figure 3 is a schematic diagram of a perspective view of a package according to the present invention in an open configuration;

[0092] Figure 4 is a schematic diagram of a package tracking system according to the present invention.

[0093] Reference Figure 1 and 4 , shows a package 1 according to the invention.

[0094] The package 1 comprises a container 2 and a closure device 3 .

[0095] like Figure 3 As shown, the container 2 has a cavity 20 .

[0096] More specifically, the container 2 is a box composed of a bottom 200 and four walls 201 extending from the bottom 200 along the periphery.

[0097] The wall 201 and the bottom 200 together define the cavity 20 .

[0098] Still refer to Figure 3 , the closure device 3 takes the shape of a lid 30 .

[0099] This cover 30 is hinged on the upper end of one of the walls 201 so as to allow or prevent access to said cavity 20 .

[0100] More generally, and with reference to Figure 1 and 3 The closure device 3 and the container 2 can be together in a closed configuration or an open configuration, in which the closure device 3 prevents access to the cavity 20 (by Figure 1 In the open configuration, the closure device 3 allows access to the cavity 20 (by Figure 3 The structure shown).

[0101] According to other conceivable and not illustrated embodiments, said container 2 may be formed by a flexible bag, and said closing means 3 would then be in the shape of a flap intended to extend over the opening of said flexible bag.

[0102] Reference Figure 1 , 2 and 3 , and as described in more detail below, each of the container 2 and the closure 3 has at least one member 21 , 31 for receiving a seal 4 .

[0103] In particular, according to the present embodiment, the container 2 has two receiving members 21 , and the closure device 3 has two receiving members 31 .

[0104] According to the principles of the invention, said package 1 also comprises a seal 4 which ensures that said package 1 is maintained in its closed configuration.

[0105] The seal 4 comprises a destructible portion 400 which is irreversibly destructible when the package 1 is switched from its closed configuration to its open configuration.

[0106] In other words, switching of the package 1 from its closed configuration to its open configuration is prevented by the seal 4 or would involve destroying the destructible portion 400 to allow opening of the package 1 .

[0107] According to this embodiment, said seal 4 takes the shape of a collar intended to be coupled to each of the receiving members 21 , 31 in the closed configuration of the package 1 .

[0108] In fact, in Figure 1 and 2 In the closed configuration of the package 1 shown, the container and the two receiving members 21 , 31 of the closure device 3 are in close proximity to each other.

[0109] In particular, when the container and the closure device are in the closed configuration of the package 1, the receiving members 21, 31 of the seal of each of the container 2 and the closure device 3 are in the shape of perforated tabs standing opposite each other, such as Figure 1 and 2 shown.

[0110] These perforated tabs each have an opening 210 , 310 allowing the seal 4 to be introduced and a collar to be formed by it.

[0111] More specifically, if Figure 2 As shown, the collar includes a head 40 and a strap 41 extending from the head 40 .

[0112] The head 40 has a disc shape.

[0113] The head 40 carries a retaining frame 42 .

[0114] The strip 41 is formed of a flexible material and is complementary to the insertion of the holder 42. In other words, the strip 41 can be inserted into the holder 42 and pass therethrough.

[0115] The collar, and more particularly the head 40 and the strip 41 , are in particular made of plastic.

[0116] As will be described below, the strip 41 forms a destructible portion 400 of the seal 4 .

[0117] More particularly, the collar is a self-locking clamp and the retainer 42 is a non-return retainer.

[0118] In other words, the introduction of the strip 41 through the cage 42 is permissible in one direction but will irreversibly result in the strip 41 being captured and retained in the cage 42 .

[0119] It is therefore not possible to remove the strip 41 from the retaining frame 42 without damaging the seal 4 .

[0120] If the package 1 is to be opened, the buckle formed by the strip 41 between the head 40 and the holder 42 must be destroyed.

[0121] For example, the buckle formed from the strip 41 must be cut using a sharp tool, such as a pair of scissors or a cutter.

[0122] Advantageously, said cage 42 and head 40 have a greater resistance to mechanical breakage than the strip 41 .

[0123] According to the principle of the present invention, Figure 2 As shown, the seal 4 comprises a radio identification electronic chip 50 and a first communication device 51 coupled to the electronic chip 50 .

[0124] The seal 4 includes an initial identification code. In other words, the identification code is written into the electronic chip 50 of the seal 4.

[0125] This initial identification code is unique to each seal.

[0126] Potentially, said initial identification code may be shared by several as yet unused seals 4. For example, these seals sharing the same initial identification code may be part of the same batch.

[0127] As described in detail below, the electronic chip 50 is designed to receive a new unique identification code.

[0128] Advantageously, this new unique identification code replaces the initial identification code written into the electronic chip 50 .

[0129] Still reference Figure 2 , the first communication device 51 includes an antenna 510.

[0130] Furthermore, the first communication means 51 extend into the destructible portion 400 of the seal 4 .

[0131] According to this embodiment, the first communication device 51 further comprises a breakable electrical conductor 511 , which couples the antenna 510 to the radio identification electronic chip 50 .

[0132] like Figure 2 As shown, the breakable electrical conductor 511 passes through the destructible portion 400 of the seal 4 .

[0133] According to another possible embodiment, the antenna 510 may be located in the destructible portion 400 of the seal 4 .

[0134] refer to Figure 2 , the antenna 510 is housed in the head 40, and the breakable electrical conductor 511 extends along the strip 41 to the free end 410 of the strip, in which the radio identification electronic chip 50 is housed.

[0135] According to this embodiment, the electronic chip 50 and the first communication device 51 are embedded in the sealing member 4 .

[0136] In particular, the antenna 510 is embedded in the material forming the head 40 of the seal 4 , and the breakable electrical conductor 511 and the electronic chip 50 are embedded in the material constituting the strip 41 .

[0137] Reference Figure 1 and 2 According to the present invention, the package 1 further comprises an electronic unit 6 .

[0138] The electronic unit 6 is used to cooperate with the sealing member 4 , more specifically, to cooperate with the radio identification electronic chip 50 and the first communication device 51 .

[0139] In practice, the electronic unit 6 comprises a transceiver 7 configured to periodically send a radio request 10 and receive a return signal 11 .

[0140] An antenna 510 located in the seal 4 allows this radio request 10 to be picked up.

[0141] After having been picked up by antenna 510 , the radio request 10 is sent to the electronic chip 50 .

[0142] According to this embodiment, the radio request 10 is transmitted to the electronic chip 50 via the breakable electrical conductor 511 .

[0143] In response to the radio request 10 , the electronic chip 50 is configured to generate a return signal 11 .

[0144] The return signal 11 is formed by integrating the identification code of the electronic chip 50. Therefore, the return signal 11 can only be generated by the seal 4.

[0145] More specifically, as described in detail below, the return signal 11 is formed by integrating a unique identification code and written into the electronic chip 50. The identification code is in particular a new unique code.

[0146] After being generated, the return signal 11 is transmitted through the divisible electrical conductor 511 and emitted by the antenna 510 .

[0147] Said transceiver 7 then allows picking up the return signal 11 emitted by the electronic chip 50 and its antenna 510 in response to the radio request 10 previously emitted.

[0148] The electronic unit 6 is also configured to detect the absence of a return signal 11 .

[0149] In practice, the electronic unit 6 comprises processing means 60 configured to record a return signal 11 transmitted in response to a radio request 10 , and to detect the absence of a return signal 11 transmitted in response to a radio request 10 .

[0150] According to the invention, the electronic unit 6 also comprises second communication means 8 configured to transmit an alarm signal 12 to a remote receiver 90 in the absence of a return signal 11 .

[0151] These second communication means 8 are controlled by the processing means 60 .

[0152] Said second communication means 8 are particularly designed to allow the transmission of the alarm signal 12 by means of wireless communication protocols, such as those implemented for cellular networks or protocols of the Bluetooth and WiFi type.

[0153] Reference Figure 1 , the electronic unit 6 also comprises means 61 for time stamping the alarm signal 12 .

[0154] according to Figure 1 and 4 The electronic unit 6 may more specifically take the form of an electronic card integrating the transceiver 7 , the second communication device 8 , the processing device 60 and the time stamping device 61 .

[0155] According to this embodiment, said electronic unit 6 is housed or even embedded in one of the walls 201 of the container 2 .

[0156] Thus, when the package 1 is in a Figure 3 In the open position shown, the electronic unit 6 is protected and possibly inaccessible.

[0157] Said package 1 comprises a battery (not shown), advantageously rechargeable, allowing the electronic unit 6 to be powered.

[0158] According to a preferred design, the transceiver 7 and antenna 510 are configured to operate in the UHF band.

[0159] Reference Figure 4 The present invention also relates to a tracking system comprising a package 1 and a computer server 9 as described above.

[0160] In this system, the remote receiver 90 is integrated into the computer server 9 .

[0161] The computer server 9 further includes a database 91 .

[0162] This database 91 lists identification codes, called “authenticated” identification codes, each of which corresponds to an initial identification code of a seal 4 .

[0163] The computer server 9 is configured to analyse the initial identification code sent by the electronic unit and compare it with the authenticated identification codes of the database 91 in order to identify the initial identification code.

[0164] This system implements a method for tracking packages 1 , which method also forms the object of the present invention.

[0165] The method includes:

[0166] - a step of transmitting, by the transceiver 7 , a radio request 10 in the direction of the seal 4 , this radio request 10 being intended to be picked up by the antenna 510 and then transmitted to the electronic chip 50 ;

[0167] A step of waiting for the reception of a return signal 11 generated by the electronic chip 50 in response to the radio request 10 .

[0168] In case no return signal 11 is received, the step of waiting for receipt of the return signal 11 is followed by a step of broadcasting the alarm signal 12 to the remote receiver 90 .

[0169] Prior to the above steps, the method also comprises a pairing sequence aimed at electronically associating the seal 4 with the electronic unit 6 of the package 1 .

[0170] To this end, the pairing sequence includes, in sequence:

[0171] - a step of reading the initial identification code of the seal 4;

[0172] - a step of sending said initial identification code to said computer server 9;

[0173] - a step of identifying said initial identification code;

[0174] - A step of generating a new unique identification code and sending the new unique identification code to the transceiver 7;

[0175] - A step of sending a new identification code by the transceiver 7 and writing it into the seal 4 .

[0176] The steps of reading the initial identification code and sending it to the computer server 9 are performed by the transceiver 7 .

[0177] After these two steps, the identification step and the step of generating and sending a new unique identification code are performed by the computer server 9 .

[0178] The identification step comprises a step of comparing the initial identification code with authenticated identification codes of database 91 in order to authenticate the seal 4 and authorize the generation of a new unique identification code.

[0179] During the step in which the transceiver 7 sends a new identification code and writes it into the seal 4, the new unique identification code may be written into the electronic chip 50 to replace the initial identification code.

[0180] If the initial identification code is found in the database 91, the seal 4 is authenticated. In other words, the seal 4 is verified and accepted in the system.

[0181] If the initial identification code is not found in the database 91 , the seal 4 is rejected.

[0182] Alternatively or additionally, the computer server 9 may send a fraudulent pairing signal to the electronic unit 6 if the seal 4 is rejected.

[0183] In this case, the system does not ensure electronic tracking of the packages 1 using the seal 4 .
