Description

[Technical Field]

[0001] The field of the invention is that of logistics, more specifically that of the design and manufacture of secure packaging and of traceability systems that allow the status of the packaging to be managed in real time.

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

[0003] Packaging allows objects to be transported within the supply chain.

[0004] Generally, a package is a container defining a cavity in which one or more objects are intended to be placed during transport.

[0005] The package also includes means for closing the package to prevent access to the cavity and its contents.

[0006] For example, a package may be formed by a case defining a cavity and one or more flaps provided by a lid movably or removably attached to the case or by the case itself. Traditionally, boxes or cardboard are used to form such packages.

[0007] In general, it is important to be able to control and / or guarantee the identity, presence and origin of the contents of a package.

[0008] For this reason, security measures may be used on the packaging.

[0009] In particular, a seal may be attached to the package to ensure that the package has not been opened.

[0010] Seals conventionally constitute a device that is fixed to the object to be protected (eg document, luggage, building, etc.) in such a way that it is not possible to proceed with opening this object without destroying and damaging the seal.

[0011] The seal may consist of a single imprint, such as a wax seal that protects documents of authenticity, or a lead seal of the type that protects water or energy consumption meters.

[0012] According to one example of a seal, plastic labels are known that are attached to two parts of a package that are intended to be spaced apart from one another to allow access to the contents of the package. These plastic labels have a dotted cut extending through them that runs along the boundary between the two parts of the package. Opening the package therefore involves tearing the label along the dotted cut, which means that the package is opened spontaneously or accidentally.

[0013] According to another example of a seal, a plastic seal is known that can ensure that a mail bag, a container, or a metal box remains in a closed configuration. The seal is generally made of a plastic material and comprises a body and a link extending from the body. The link is relatively flexible and is intended to form a loop to engage with a complementary opening provided by the body. The opening and the link are designed so that insertion of the link into the opening is irreversible, and only irreversible destruction of the seal allows the loop to open.

[0014] Thus, the seal, according to a typical design, comprises a portion that can be irreversibly broken during opening of the item to which the seal is attached.

[0015] Such a seal is particularly easy to manufacture and implement.

[0016] These seals may be described as "generic" because they are designed to be used in a variety of situations and with a variety of types of objects or containers.

[0017] Nevertheless, there appears to be a desire for more specific integration of seals into packaging, particularly into what are called "reusable" packaging.

[0018] Additionally, the seals described above do not allow one to know exactly when an object has been opened, particularly in real time or non-real time by a timestamp, or even to know the status of the seal without direct visual confirmation of the sealed object, which is sometimes or often not possible.

[0019] It is also known in the field of the present invention to use labels on wine bottles that incorporate a unique identifier such as an alphanumeric reference number, a bar code, or a radio frequency identification (RFID) means.

[0020] Although such identification means provide improved information about the labeled product, they do not fully satisfy the stated needs. Summary of the Invention

[0021] The present invention is particularly aimed at meeting the need for more specific integration of seals into packaging.

[0022] More specifically, the present invention aims to propose a package having a specially designed seal integrated into the package, which has an additional capability of controlling the state of the seal, different from the capability of controlling the state of the seal in the field by sight.

[0023] It is also an object of the present invention to provide such a package which makes it possible to know exactly when the seal has been broken, for example during opening of the package.

[0024] It is also an object of the present invention to provide such a package which is easy to seal.

[0025] These objects, and others that will appear hereinafter, are achieved thanks to the present invention, which relates to a package comprising: a container having a cavity and a female member, referred to as the first female member; - a closing means; a seal; the package having a closed configuration in which the closure prevents access to the cavity and an open configuration in which the closure allows access to the cavity; The seal is intended to ensure that the package remains in its closed configuration; The seal is a male member, referred to as the first male member, that is complementary to the first female member; at least one irreversibly breakable portion; the seal is intended to be attached to the package in an attachment position that ensures the package remains closed, the first male member being held fixed and confined within the first female member in the attachment position; the breakable portion is irreversibly breakable during transition of the package from a closed configuration to an open configuration with the seal in its attached position or during opening of the seal; the seal comprises a component for managing the integrity of the seal, the managing component being at least partially integrated into the breakable portion; The package is provided with an electronic unit for controlling the integrity of the seal, the electronic unit being - means for detecting corruption of the management component; means for activating the detection means during placement of the seal in its mounting position.

[0026] The package according to the invention is provided with a seal specially designed for the container.

[0027] In fact, the seal has a predetermined position when it is activated, since it must be fixed to the container, and this position corresponds to its so-called "position that ensures that the package remains closed".

[0028] Thanks to the control electronic unit, an additional control of the seal status is carried out, different from the mundane visual control of the seal.

[0029] This control is performed by the detection means and is initiated simply and automatically during installation of the seal. This automatic initiation is made possible by means for activating the detection means. The sole act of fixing the seal in its predetermined position activates the detection means.

[0030] The sealing is therefore particularly simple and quick to carry out.

[0031] According to one preferred embodiment, the closure means has a female member, called the second female member, The seal is a second male member complementary to the second female member; a body extending longitudinally between the male members and having at least one breakable portion; the second male member is intended to be maintained fixedly and confined within the second female member in the attached position; The body of the seal is positioned to overlap the interface between the container and the closure at the seal installation location.

[0032] Thanks to this embodiment, the seal conforms to the surface of the package between the two female members provided by the container and the closure means, respectively.

[0033] The seal is therefore secured on either side of the boundary when in its installed position ensuring that the package remains closed.

[0034] In this case, according to one advantageous feature, in the mounting position of the seal, the body of the seal fits the contour of the package between the first and second female members.

[0035] By mating with the contour of the package between the first and second female members, the seal is forced against the contour of the package at its attachment location, at least between the two male members.

[0036] In this way, the seal extends freely from the package between its two male members and has no portions that may be accidentally torn off during handling or dropping of the package.

[0037] According to one preferred solution, in the mounting portion of the seal, the body of the seal is received in grooves provided by the container and the closure means, the body of the seal having a thickness less than or equal to the depth of each of the grooves.

[0038] In this way, the seal is protected within the groove during handling of the package.

[0039] In other words, the seal, when in its installed position, does not protrude out of the groove provided by the package.

[0040] If the package were to come into contact with a foreign object at the seal, it is likely that the groove edge itself would come into contact with the foreign object and the seal would not be subjected to forces that would likely damage it.

[0041] Preferably, the body has a central portion located between the first and second male members and bordered by two breakable portions, the central portion intended to be separated during opening of the seal.

[0042] The seal therefore has an intuitive operation during opening of the seal, which requires, for example, simply tearing off this central portion.

[0043] The breakable portion may then be formed, for example, by a pre-cut that weakens the body in a predetermined manner.

[0044] Advantageously, the management element comprises a conductive track.

[0045] In this way, when the breakable part is irreversibly broken during the transition of the package from its closed configuration to its open configuration or during the opening of the seal, the electrical continuity of the conductive track is interrupted and it is this break that can be detected by the detection means.

[0046] For example, a direct or variable current periodically sent by the detection means can indicate whether the conductive track is intact.

[0047] If sending a direct current or electrical pulse into the conductive track is unsuccessful, the seal is broken or absent, which corresponds to opening the seal.

[0048] According to one preferred solution: the management component has at least one conductive terminal; the activation means comprises a connector for each terminal of the management component; In the installed position of the seal, the connector or connectors come into contact with the terminal or terminals.

[0049] Thanks to this solution, electrical contact between the connector and the terminals can be achieved by simple attachment of the seal to the package.

[0050] This solution is particularly easy to implement.

[0051] Advantageously, the management component comprises electronic components for wireless communication with the electronic unit.

[0052] In this way, the seal can send information to the electronic unit and inform it of its status without a wired connection.

[0053] For example, the wireless communication electronic component may be a radio frequency identification (also represented by the acronym RFID) antenna that will be coupled to a conductive track of a management component at least partly integrated in the breakable part.

[0054] In this case, the management component preferably comprises a memory that integrates the unique identifier.

[0055] This allows you to know exactly which seal is located on the package.

[0056] This unique identifier allows the use of incompatible or non-accepted seals to be avoided in a traceability system implementing a package according to the present invention.

[0057] According to one variant embodiment, the electronic unit comprises means for wireless communication with a remote computer server, and the electronic unit is configured to issue an alert to the remote computer server via the wireless communication means upon detection of corruption of the management component by the detection means.

[0058] By virtue of this variant embodiment, the package has the ability to communicate the state of the seal to a remote computer server.

[0059] Thus, according to one possible application, the ultimate recipient of a package can be notified, prior to receipt, whether their package has been opened, or more specifically, whether it has been tampered with, and can learn of this event either simultaneously or shortly after it occurs.

[0060] Other characteristics and advantages of the present invention will appear more clearly on studying the following description of various preferred embodiments of the invention, given as illustrative and non-limiting examples, and the accompanying drawings, in which: [Brief explanation of the drawings]

[0062] 1a, 1b and 6, a package 1 according to the present invention is shown.

[0063] The package 1 comprises a container 2 having a cavity 20. The cavity 20 is intended to contain, for example, an object intended to be transported.

[0064] The package 1 further comprises a closure means 3 for closing the cavity 20 .

[0065] The closure means 3 is formed by a lid.

[0066] The lid, still according to this embodiment, is movably attached to the container 2. More specifically, the lid is rotatably attached to the rear panel 203 of the container 2.

[0067] According to one possible embodiment, the lid may be intended to be removable and simply attached to the container 2 .

[0068] More specifically, with reference to Figures 1a and 1b, the package may be in a closed configuration (Figure 1a) or an open configuration (Figure 1b).

[0069] In the closed configuration, the closure means 3 prevents access to the cavity 20, and in the open configuration, the closure means 3 allows access to the cavity 20.

[0070] In these use and closed configurations, the container 2 is shaped to define a cavity 20. This container 2 is in particular in the form of a case.

[0071] According to this embodiment, the package 1 may also have a flattened form, as will be described in more detail below.

[0072] More specifically, the container 2 comprises a bottom 204 and a peripheral portion, which consists of a front panel 201, two side panels 202, and a rear panel 203.

[0073] As shown in Figure 6, the package 1 can be folded into a flat configuration in which the side panels 202 are lowered onto the bottom 204, the rear panel 203 is lowered onto an extension of the bottom 204, and the front panel 201 and lid (forming the closure means 3) are lowered onto the bottom 204 overlapping the side panels 202, with the lid extending onto an extension of the front panel 201.

[0074] In the flattened configuration, the package 1 has minimal bulk.

[0075] In accordance with the principles of the present invention, and with reference to Figures 1a to 6, package 1 comprises at least one seal 4 intended to ensure that package 1 is maintained in its closed configuration, i.e., that package 1 is maintained in its closed configuration throughout shipment.

[0076] For this purpose, the container 2 has a female member called the first female member 21 and the seal 4 has a male member called the first male member 41. The first male member 41 is complementary to the first female member 21.

[0077] The seal 4 is intended to be placed in an attachment position on the package 1. The seal ensures that the package 1 remains closed in the attachment position, i.e. the package 1 remains closed. In this position, the first male member 41 remains fixed and confined within the first female member 21.

[0078] According to this embodiment, the closure means 3 is formed by a lid and has a female member called second female member 31. The seal 4 comprises another male member called second male member 42. The second male member 42 is complementary to the second female member 31.

[0079] Similar to the first male and first female members, this second male member is intended to be maintained fixedly and confined within the second female member at the location of the seal 4 attachment.

[0080] 2 through 5, still in accordance with the principles of the present invention, seal 4 comprises at least one breakable portion 400. Breakable portion 400 is breakable during transition of package 1 from a closed configuration to an open configuration with seal 4 in its attached position, or during opening of seal 4.

[0081] Breakable portion 400 is irreversibly breakable, in other words, once breakable portion 400 is broken, it cannot return to its original unbroken state.

[0082] According to this embodiment, the seal 4 comprises two breakable portions 400 .

[0083] These breakable portions 400 are formed by pre-cuts, i.e., cuts that cause the seal 4 to break.

[0084] According to this embodiment, the seal 4 comprises a body 40 extending longitudinally between the male members and having a breakable portion 400 .

[0085] 1a, 2 and 5c, the body 40 of the seal 4 is positioned to overlap the interface between the container 2 and the closure 3 at the installation position of the seal 4.

[0086] More specifically, in this installed position of the seal 4, the body 40 of the seal fits the contours of the package 1 between the first female member 21 and the second female member 31.

[0087] This body 40 is in particular formed by a strip.

[0088] The main body 40 is a first portion 401 that holds a first male member 41 that protrudes from the underside of the main body 40; a second portion 402 that holds a second male member 42 that protrudes from the underside of the main body 40;

[0089] The main body 40 has a central portion 403 between the first portion 401 and the second portion 402 .

[0090] In other words, the central portion 403 is located between the first male member 41 and the second male member 42.

[0091] The first 401 and second 402 parts of the body 40 of the seal are separated from the central part 403 by two breakable parts 400. The central part 403 is thus bordered by the two breakable parts 400, and this central part is intended to be separated during opening of the seal 4.

[0092] 5c, the seal 4, and in particular its body 40, is flexible, which allows the seal 4 to deform so as to fit the contours of the package 1.

[0093] According to this embodiment, with reference to Figures 1a, 2 and 5a, the container 2 and the closure means 3 have a groove 7 for each seal 4. Each seal 4 is intended to be received in a complementary groove 7 and to be protected within these grooves. In fact, the body 40 of the seal has a thickness equal to or less than the depth of the groove 7. In this way, the body 40 of the seal does not protrude from the groove 7.

[0094] 2, 3 and 4, the first male member 41 is formed by an elastically deformable hook.

[0095] More specifically, the first male member 41 takes the shape of an arrow having a rigid central rod and two elastically deformable fins.

[0096] The two fins are elastically deformable to allow, by forced folding of the fins, the insertion of the hooks inside the first female member 21. When the first male member 41 is pressed down sufficiently, the elastically deformable fins tend to unfold and re-occupy their rest position, thus achieving fixation of the first male member 41 within the first female member 21.

[0097] When the first male member 41 is within the first female member 21, it is locked in place and can only be withdrawn by sliding the first male member 41 in the opposite direction to the second male member 42.

[0098] 3 and 4, the second male member 42 takes the form of a single inelastically deformable hook, which is intended to be inserted into the second female member 31.

[0099] In fact, the second female member 31 is a rear hollow portion into which the second male member 42 can be inserted, the rear hollow portion being located towards the rear of the second male member 42; a complementary front hollow section for the insertion and fixation of the second male member 42, The second male member can slide from the rear hollow portion of the second female member 31 to the front hollow portion.

[0100] The second male member 42 is fixed in place when in the front portion of the second female member 31 and can only be withdrawn by sliding it towards the rear portion.

[0101] 5a to 5c, which illustrate the kinematics for deploying the seal 4, the second male member 42 must first be inserted into the second female member 31 by inserting it into the rear hollow portion of the second female member 31. The seal 4, and therefore the second male member 42, must then be slid towards the first female member 21 to move the second male member 42 into the front hollow portion of the second female member 31.

[0102] To complete the installation of the seal 4, it is sufficient to fasten the first male member 41 to the first female member 21 provided by the container 2.

[0103] Referring to Figure 2, the seal 4 is held in place by the male and female members and the body 40 of the seal 4 stretched between them.

[0104] Following the opening of the seal 4, and more specifically the separation of the central portion 403 of the body 40 from the seal 4, the first portion 401 of the body 40 of the seal 4 can then be slid downwards, thereby disengaging the first male member 41 from the cavity formed by the first female member 21, and the second portion 402 of the body 40 of the seal 4 can be slid backwards, withdrawing the second male member 42 from the cavity formed by the second female member 31.

[0105] With reference to FIG. 2, the seal 4 comprises a component 5 for managing the integrity of the seal 4 (represented by a dotted line), as will be explained in more detail below.

[0106] This management component 5 is at least partially integrated into the breakable part 400 .

[0107] The package 1 further comprises an electronic unit 6 for managing the integrity of the seal 4 .

[0108] This electronic unit 6 is housed in a cavity 20 or, more advantageously, inside the walls of the enclosure 2 , more particularly inside the front panel 201 .

[0109] The electronic unit 6 comprises means 61 for detecting a breakage of the component 5 for managing the seal 4 .

[0110] In particular, the management component 5 passes through one or more breakable portions 400 .

[0111] In this way, during the opening of the seal and the irreversible breaking of one of the breakable parts 400, the management component 5 is also broken.

[0112] The detection means 61 of the electronic unit 6 are therefore designed to detect any breakage of this management component 5 .

[0113] The electronic unit 6 further comprises means for activating the detection means 61 during placement of the seal 4 in its mounting position.

[0114] This activation means makes it possible to activate the detection means 61 as soon as the seal 4 is placed on the package 1 .

[0115] Referring to FIG. 2, the management component 5 comprises conductive tracks 50 .

[0116] The conductive tracks 50 are components of an electrical circuit.

[0117] According to this embodiment, still referring to FIG. 2, the management component 5 comprises at least one conductive terminal 51 connected to a conductive track 50 .

[0118] And in this case, the means for activating the electronic unit 6 comprise a connector 62 for each terminal 51 of the management component 5 .

[0119] 2, when the seal 4 is in the attached position, the connector 62 comes into contact with one or more terminals 51.

[0120] Thus, attachment of the seal 4 to the package 1 electrically couples one or more terminals 51 provided by the seal to a connector 62 provided by the receptacle 2 of the package 1, completing an electrical circuit.

[0121] According to one possible embodiment, not shown, the management component 5 further comprises electronics for wireless communication with the electronic unit 6. Such wireless communication electronics may be formed by an RFID antenna, in particular a UHF (ultra high frequency) or NFC (near field communication) antenna, associated with the conductive track 50.

[0122] The electronic unit 6 is then provided with a transceiver that sends a signal to the RFID antenna and in turn is intended to wait for a signal returned by the RFID antenna to check that the condition of the seal 4 is still intact. If the breakable part 400 is damaged, the conductive track 50 is destroyed and the RFID antenna is unable to return a signal. The lack of a reply makes it possible to determine that the seal 4 has been broken.

[0123] According to another possible embodiment, the management component may be formed by a magnetic element, and the detection means 61 and the means for activating the electronic unit 6 may be formed by a Hall effect sensor that detects the presence or absence of magnetism in the magnetic element, the absence of magnetism corresponding to a break in the seal 4.

[0124] To prevent any fraudulent activity, ie quickly replacing the seal 4 with a magnet, the electronic unit 6 analyses the variations in the magnetic field over a period of time.

[0125] A period without magnetic field for too long corresponds to a breakage of the seal 4. Furthermore, if the sensor is under the influence of a strong magnetic source for a period longer than a threshold defined by the electronic unit 6, causing the sensor to become inactive and making it impossible to detect the presence of the seal, an alert of attempted fraud is generated.

[0126] The management component 5 may further comprise a memory incorporating the unique identifier, such memory enabling the electronic unit 6 to determine which seal 4 is attached to the package 1.

[0127] In this case, the electronic unit 6 is configured to recognise the unique identifier and to be able to activate or deactivate the sticker 4 .

[0128] Referring to FIG. 2, the electronic unit 6 may further comprise means 63 for wireless communication with a remote computer server.

[0129] In this case, the electronic unit 6 is arranged to issue an alert via wireless communication means 63 to a remote computer server upon detection by the detection means 61 of corruption of the management component 5 .

[0130] Referring to Figure 6, the seals 4 can also be used when the package 1 is in its flat configuration. For this purpose, as shown by Figure 1a, the package 1 is provided with a second fixing point 8 for each male member, i.e., a first male member 41 or a second male member 42, for each seal 4.

[0131] This second fixing point 8 is designed to compensate, if necessary, for the difference in length that occurs between the first female member 21 and the second female member 31 when the package 1 is in its flattened configuration compared to its molded configuration.

[0132] According to this embodiment shown in Figures 1a and 6, the length that exists between the two female members when the package 1 is in its flat configuration is shorter than the length that exists between the two female members when the package 1 is in its use configuration.

[0133] As a result, the second fastening point 8 is spaced from the second female member 31, allowing the seal 4 to be compatible with this fastening system as well.
