Description

Method for controlling products, in particular cosmetic products, control system and associated computer program product

The present invention relates to a method for monitoring and controlling products.

The present invention also relates to a product monitoring and control system and an associated computer program product.

This system is in particular intended for the control of cosmetic products.

Each cosmetic product is typically contained in a packaging such as a jar, a bottle or a bottle. In known manner, a user of cosmetic products generally has a plurality of packaging which he has for example in a drawer or a cupboard in his bathroom after their purchase. When one of the packages is opened for the first time, the product contained inside gradually degrades until its use by the user is no longer recommended. A recommended duration of use after opening is thus usually written on the packaging. For cosmetic products, this duration is typically of the order of several months, in particular 6 months, 12 months or even 24 months depending on the product. Depending on its nature, a product may also have a use-by or best-before date.

However, it is complicated for the user to follow the duration after opening of each packaging, especially when there are many of them and when the opening dates as well as the recommended durations of use after opening of each packaging are different. Due to the uncertainty of the user vis-à-vis the different opening times, the result is that the user regularly discards the packaging prematurely out of caution or, conversely, that he uses the product after its recommended duration of use. Consequently, this uncertainty leads either to a waste of product, or a risk of ineffectiveness of the product, or even a risk for the health of the user.

It is known from document US9961984 to carry out an inventory of products available in a reserve by querying RFID tags carried by the packaging of said products. The document US9961984 allows a simple follow-up of the stocks of products available but is not able to follow the integrity.

We know from document EP3070648A1 a system for detecting the opening of a lifejacket in an airplane. By means of an RFID tag with a frangible part arranged in such a way as to break when the lifejacket is opened, the system is able to know the state of each lifejacket during a RFID query request. However, when the lifejacket is used, it must be replaced as soon as possible regardless of the date on which its integrity was altered.

Although more particularly intended for monitoring the integrity of the life jackets available on board, the system is applicable to securing compartments or trunks, the RFID tag being placed astride a line of demarcation between an opening (door leaf ) and a fixed part (door frame).

Document US 2002/0188259 A1 also discloses a system for managing the expiry date of products in a hospital environment. Although the system is designed to indicate whether the product has already been used or not, there is no mention of any management of the duration after opening each product.

An object of the invention is therefore to propose a product control process allowing improved monitoring and control of the durations after opening of the associated packaging, in order to reduce product waste and health risks for the user.

For all intents and purposes, it should be noted that in the context of the present application, the concept of duration of use after opening means the initial opening as defined in the ANSM recommendation, i.e. i.e. the opening of the product during its first use by the final consumer.

To this end, the subject of the invention is a method for checking the status of first opening of products, in particular cosmetic products, by a control system, comprising the steps aimed at:

• emitting a radio frequency identification interrogation signal and receiving the signal(s) emitted in response by one or more packages present in an interrogation zone and equipped with a functional radio frequency identification tag,
• read the signal(s) received in response so as to extract for each signal at least one item of packaging identification data and, where applicable, its first opening status,
• search for the packaging identified in a list of packaging identified during a previous reading step and,

+ in the case of a newly identified packaging, save it, if necessary with its status of first opening, in the list of packaging by associating a timestamp data of the new detection of said packaging,

+ in the case of previously identified packaging, associate with it an updated timestamp corresponding to the last reading and, if necessary, update its status of first opening.

According to other advantageous aspects of the invention, the control method comprises one or more of the following characteristics, taken in isolation or in all technically possible combinations:

- it includes an initialization step aimed at:

+transmit a radio frequency identification interrogation signal and receive the signal(s) emitted in response by one or more packages present in the interrogation zone and equipped with a functional radio frequency identification tag,

+ read the signal(s) received in response so as to extract for each signal at least one piece of packaging identification data and, where applicable, its first opening status,

+record each packaging identified and, where applicable, its status in the list of packaging by associating a timestamp of the detection of the packaging;

- the packaging identification data read during the query step is associated with a commercial name of the product, in particular by querying a product database, in particular an external database;

- the initialization step can be triggered manually by the user;

- the initialization stage is triggered automatically, in particular when the control system is first started;

- for an identified packaging having a status of first opening, an opening duration of said packaging is determined from the associated timestamp data corresponding either to the timestamp data of the reading at which an opening status has been read, or to the timestamp of the immediately preceding reading;

- it includes a step of alerting the user, when the determined duration of opening is greater than a duration of use after opening recommended for an identified product, said recommended duration of use being obtained by querying a database corresponding product data;

- for an identified packaging, a duration of presence in the radio frequency identification interrogation zone since the first detection is determined.

The invention also relates to a method for determining a duration of opening of products, in particular cosmetic products, each product being contained in an associated packaging, each packaging being capable of passing from a sealed configuration to an unsealed configuration. from the first opening of said packaging, each packaging being provided with an electronic label, each electronic label being configured to supply at least one signal comprising information representative of the associated product and of the configuration in which the associated packaging is located, the method of control comprising at least the following steps:

• reading at a plurality of successive reading times of the information provided by at least one electronic tag,
• recording in a database of the information and the associated reading time, and

determination of a duration of opening of the at least one packaging associated with the duration of presence of said packaging in the unsealed configuration from the information and the reading time recorded in the database.

Thanks to the regular reading of the signals contained in each electronic label, it is possible to precisely follow the opening time of each packaging. Indeed, it is possible to detect the passage of a packaging from the sealed configuration to the unsealed configuration, then to follow the duration of opening of the packaging. The user thus has a precise knowledge of the duration of opening of each of his packaging and thus does not throw away products prematurely or does not use a product too late.

According to a variant, the opening duration is determined from the recorded reading time associated with a change in configuration of the packaging or from the directly prior recorded reading time associated with a change in configuration of the packaging.

The opening time is thus determined either at the time of detection of the configuration change or, conservatively, from the last moment of reading prior to the detection of the configuration change.

According to a variant, the determination method further comprises the following steps:

• comparison, for each packaging, of the opening time of the packaging with an associated predetermined maximum opening time;
• comparison, for each packaging, of an expiry date of the associated product with the current date;

generation of an alert when the opening time of one of the packaging is greater than the predetermined maximum open time associated with said packaging and/or when the expiry date of one of the products is greater than the current date .

These different steps make it possible to detect when the opening time of a packaging is greater than the associated predetermined maximum opening time and to generate an alert for the user in this case. The user is thus easily informed when a product is no longer usable. Similarly, monitoring the expiry date of each product alerts the user if this expiry date is exceeded.

The invention also relates to a system for checking products, in particular cosmetic products, comprising a reader capable of reading, at a plurality of successive reading times, the signals supplied by at least one electronic label of at least one product packaging, each packaging being capable of changing from a sealed configuration to an unsealed configuration from the first opening of said packaging, each electronic tag being configured to supply at least one signal representative of the associated product and one signal representative of the configuration in which the packaging is located associated, and a processing module configured to record in a database the information and the associated reading time, and to determine an opening duration of each packaging associated with the duration of presence of said packaging in the unsealed configuration from the recorded information and playback time d in the database

According to a variant, the control system further comprises a communication module configured to send each opening duration to a database, the database being in particular consultable by means of a mobile terminal.

Thus, all opening times are reliably stored digitally and the user can easily view these opening times in the database.

According to a variant, the communication module is also configured to receive a read command, the reader being able to read the signals provided by each electronic tag at the time of receipt of the read command.

The reading of electronic labels on receipt of a reading order, in particular sent by a mobile terminal of the user, makes it possible to have precise and updated feedback on all the configurations of the packaging and therefore the associated opening times. . It is thus possible for the user to obtain information on the status of his products at any time, for example when he is shopping.

According to a variant, the reader is capable of reading the signals supplied by each electronic tag at a frequency of between 2 and 15 readings per week, in particular one reading per day.

This frequency allows a regular control of the configuration of each packaging and a sufficiently precise temporal detection of the opening of a packaging.

According to variants:

• the processing module is further configured to compare, for each packaging, the opening time of the packaging with an associated predetermined maximum opening time;
• each electronic tag is further configured to provide a signal relating to an expiry date of the product associated with the packaging; And
• the system further comprises an alert module configured to generate an alert when the opening time of one of the packaging is greater than the predetermined maximum open time associated with said packaging and/or when the expiry date of the one of the products is greater than the current date.

According to a variant, the control system further comprises a generation module configured to consult a meteorological database and to generate product suggestions at least as a function of the meteorological data, of each product and of the duration of opening of each packaging contained in the control system.

The generation module allows the user to receive personalized suggestions taking into account the weather conditions and the state of his products. It is thus possible to recommend a sunscreen to the user in case of strong sun or to suggest a new product to him when the maximum duration of opening of the product is almost reached and to avoid a shortage of this product for the user.

According to variants:

• the system further comprises a receptacle suitable for receiving each packaging;
• the system further comprises a box adapted to be placed in the receptacle in a removable manner, the reader being placed in the box.

The removable box makes it easy to implement the invention in a receptacle that may already be installed, such as a bathroom cabinet.

According to a variant, the receptacle comprises a plurality of walls, the reader being arranged in one of the walls of the receptacle.

The reader is then integrated into the receptacle and has a reduced size.

The invention also relates to an assembly comprising at least one product packaging, each packaging being able to pass from a sealed configuration to an unsealed configuration from the first opening of said packaging, each packaging being provided with an electronic label, each electronic label being configured to provide at least one signal representative of the associated product and one signal representative of the configuration in which the associated packaging is located, and a control system as defined above configured to control the or each product contained in the at least one conditioning.

The invention also relates to a computer program product comprising the software instructions, which when they are implemented by computer equipment, implement the control method as defined above.

The invention will be better understood on reading the following description, given solely by way of example, and made with reference to the appended drawings, in which:

- there is a perspective view of a first embodiment of a product control system according to the invention,

- there is a schematic representation of the product control system of the ,

- there is a side view of a product packaging suitable for being checked by the quality control system , And

- there is a perspective view of a second embodiment of a product control system according to the invention.

A product control system 10 according to a first embodiment is illustrated in the .

The control system 10 comprises at least one product packaging 12, a reader 14 and a processing module 16.

The control system 10 also advantageously comprises a communication module 18, a database 19 comprising a list of packaging 12 present in an identification zone, an alert module 20, a generation module 22 and advantageously a receptacle 24 for packaging 12.

As seen on the , the packaging 12 comprises a reservoir 26, a dispensing head 28 and an electronic tag 30.

Reservoir 26 contains a product, in particular a cosmetic product.

A cosmetic product is in particular a product as defined in EC Regulation No. 1223/2009 of the European Parliament and of the Council dated November 30, 2009, relating to cosmetic products.

The dispensing head 28 is configured to dispense the product contained in the reservoir 26 outside the packaging 12.

The dispensing head 28 is for example a cap capable of pivoting on the reservoir 26 as illustrated in the , a clean plug to be screwed/unscrewed on the tank 26 or even a push button.

The packaging 12 is capable of changing from a sealed configuration to an unsealed configuration.

In the sealed configuration, the dispensing head 28 is permanently attached to the reservoir 26 and the dispensing of product is prevented.

In other words, packaging 12 is in the sealed configuration when packaging 12 has never been opened and has not yet dispensed product.

The packaging 12 is in particular in the sealed configuration when it is commercially available.

The packaging 12 then has a negative status of first opening.

The packaging 12 is able to pass into the unsealed configuration from the first opening of the packaging 12, as shown in the .

In other words, the packaging 12 is in the unsealed configuration from the first separation of the dispensing head 28 and the reservoir 26 and/or from the first dispensing of product.

Those skilled in the art will therefore understand that, in the context of the present description, the packaging 12 is in the unsealed configuration, even when the dispensing head 28 is closed on the reservoir 26, as soon as the first opening of the packaging 12 has already occurred.

The packaging 12 then has a positive first opening status.

The electronic tag 30 advantageously comprises an RFID chip (from the English “radio frequency identification” meaning in French “radio frequency identification”), a memory comprising the information and an antenna.

Subsequently, the electronic tag 30 is also called the radio frequency identification tag 30.

The electronic tag 30 is capable of receiving an electromagnetic wave via the antenna. This wave activates the RFID chip which in return sends back an electromagnetic signal representative of at least one piece of information, for example stored in the memory.

Alternatively, each electronic tag 30 is an NFC chip (in English "Near Field Communication" which means "near field communication"), allowing reading in the near field by the reader 14, with a maximum distance of about 4 cm between the electronic tag 30 and the reader 14.

We know in particular such NFC chips produced by the company Talkin’Things.

The electronic tag 30 is configured to provide at least one signal comprising information representative of the associated product and information representative of the configuration in which the associated packaging 12 is located.

The electronic tag 30 provides for example a single signal comprising the two information items coded in this single signal.

As a variant, the electronic tag 30 provides two distinct signals each comprising respective information.

The signal representative of the associated product is for example relative to a unique reference number associated with the product.

The electronic label 30 is for example placed, at least partially, under the conventional packaging presentation label 12.

The electronic tag 30 advantageously extends in the sealed configuration on the reservoir 26 and on the dispensing head 28.

The signal representative of the configuration in which the packaging 12 is located is notably associated with the partial rupture of the electronic tag 30 between the reservoir 26 and on the dispensing head 28 during the first opening of the packaging 12, as visible on the .

Thus, the electronic tag 30 is thus configured to provide a first signal associated with a first configuration identifier when the electronic tag 30 is intact and a second signal associated with a second configuration identifier when the electronic tag 30 is broken.

A configuration change is therefore detected by a modification of the configuration identifier.

Alternatively, the electronic tag 30 does not break when switching from the sealed configuration to the unsealed configuration. The electronic tag 30 is then able to provide a first signal when the packaging 12 is in the sealed configuration and a second signal when the packaging is in the unsealed configuration.

A configuration change is therefore also detected by a modification of the configuration identifier.

As a further variant, the electronic tag 30 is capable of providing a signal when the packaging 12 is in the sealed configuration and an absence of signal when the packaging is in the unsealed configuration.

A configuration change is therefore detected by the absence of a configuration identifier when a configuration identifier was present previously.

Advantageously, the electronic label 30 is also configured to provide information relating to an expiry date of the product associated with the packaging 12.

The expiry date is the expiry date of the product, whether or not the associated packaging 12 is opened.

As a variant, the expiry date of each product is stored in the database 19 and thus accessible from the signal representative of the product.

The reader 14 is able to read at a plurality of successive reading times the signals provided by each electronic tag 30 in the interrogation zone.

For example, the reader 14 is capable of periodically reading the signals provided by each electronic tag 30.

The term “periodically” is understood to mean reproducing at various predetermined intervals, the intervals possibly being regular.

In particular, the reader 14 is able to read the signals supplied by each electronic tag 30 at a frequency of between 2 and 15 readings per week, in particular one reading per day.

In particular, the reader 14 is capable of creating a magnetic field oriented in the direction of the packaging 12 in order to activate the various electronic labels 30.

The reader 14 further comprises an antenna capable of receiving the signal in the form of an electromagnetic wave emitted by each electronic tag 30 in response to the activation of the latter.

The reader 14 is able to read the signals provided by each electronic tag 30 according to a communication protocol called UHF mode.

In such a communication protocol, the reader 14 is capable of transmitting or receiving a signal having a frequency comprised between 300 MHz and 3000 MHz.

The reader 14 is in particular configured to read the signal representative of the configuration in which the packaging 12 is located associated with the electronic tag 30.

Indeed, the signal emitted by the electronic tag 30 in response to the request of the reader 14 is different in the event of partial rupture of the electronic tag 30.

The reader 14 therefore receives a different signal when the packaging 12 passes from the sealed configuration to the unsealed configuration.

In particular, reader 14 receives the first signal relating to the first identifier when the electronic tag 30 is intact and the second signal relating to the second identifier when the electronic tag 30 is broken.

The reader 14 is able to transmit the signals received from the electronic labels 30 to the processing module 16.

At each interrogation, the reader 14 is also capable of determining and transmitting to the database the moment of reading at which the interrogation took place. This moment of reading is for example determined in the form of timestamp data representative of the day and advantageously of the time at which the interrogation was implemented.

From the signals received from the reader 14, the processing module 16 is configured to identify the product associated with the electronic label 30 and to detect the passage of the packaging 12 from the sealed configuration to the unsealed configuration as well as the moment of this reading.

The processing module 16 is configured to record in the database 19 the information obtained at each moment of reading, and associated with the information, the associated moment of reading.

In particular, if the product identifier is not already present in the database 19, the processing module 16 adds this new identifier and the associated product in the database 19 as well as the corresponding associated configuration and the time of reading.

If the product identifier is already present in the database 19, the processing module 16 updates the corresponding associated configuration and the reading time.

Thus, the database 19 preferably comprises at least one table comprising, for each product whose label has been queried, the identifier of the product, the associated configuration of the product and the associated reading time.

The processing module 16 is configured to determine a duration of opening of each packaging 12 associated with the duration of presence of said packaging 12 in the unsealed configuration.

The opening time is determined from the recorded reading time associated with a change in configuration of packaging 12, as defined above, or from the directly prior recorded reading time associated with a change in configuration of packaging 12, as defined above.

The processing module 16 is in particular configured to determine the opening date of the packaging 12 and compare it to the current date, for example given from a calendar integrated into the control system 10, in order to calculate the duration of opening of each packaging 12.

Advantageously, the processing module 16 is also configured to compare, for each packaging 12, the duration of opening of the packaging 12 with an associated predetermined maximum opening duration.

The predetermined maximum opening time is a time, for example, indicated by the product manufacturer. The predetermined maximum opening time represents the maximum time beyond which the product becomes significantly less effective, even dangerous for the health of the user.

Each predetermined maximum opening time is for example stored in the database 19.

Advantageously again, the processing module 16 is configured to compare, for each packaging 12, the expiry date with the current date.

The processing module 16 is configured to transmit each configuration, each opening time and the comparisons with respect to the predetermined maximum open time and with respect to the expiry date for each packaging 12 to the communication module 18 and to the module alert 20.

The communication module 18 is configured to send each conditioning 12, the configuration, the opening duration and the comparison with the predetermined maximum opening duration to the database 19.

The database 19 is located for example at a distance from the packaging 12, in particular on a remote server.

The database 19 can be consulted in particular by means of a mobile terminal, in particular a smart phone or a tablet, or even a fixed terminal via a query via the Internet.

The user is thus able to easily consult the configuration and the duration of opening of each packaging 12 and the comparison with the predetermined maximum opening duration by means of such a mobile terminal.

The communication module 18 is further configured to receive a read command, in particular from a mobile terminal of the user.

The communication module 18 is then configured to transmit this read command to the reader 14.

The reader 14 is able to read the signals supplied by each electronic tag 30 when the read command is received.

This reading allows the user to have precise and updated feedback on all the configurations of packaging 12 and therefore the associated opening times.

The alert module 20 is configured to generate an alert when the opening time of one of the packagings 12 is greater than the predetermined maximum opening time associated with said packaging 12 and/or when the expiry date of the one of the products is greater than the current date.

The alert is for example a text message sent to the user's mobile terminal or a message displayed on a screen placed on the receptacle 24.

The generation module 22 is configured to consult a meteorological database and to generate product suggestions at least as a function of the meteorological data, of each product and of the duration of opening of each packaging 12 contained in the control system 10 .

In particular, the Generation 22 module is configured to suggest to the user products that are relevant to the current weather conditions, such as sunscreen in sunny weather or a moisturizer in cold weather.

The generation module 22 is further configured to suggest a new product to the user based on the products already present in the control system 10 from a list of products of interest to the user such as soap or toothpaste by example.

The generation 22 module is further configured to suggest a product to the user when the expiry date of said product is approaching or when the maximum open time of said product is almost reached.

As seen on the , the receptacle 24 is suitable for receiving the packaging 12.

The receptacle 24 then constitutes the interrogation zone of the reader 14.

The receptacle 24 is here a cabinet. The receptacle 24 is alternatively a drawer, as shown in the , or a box for example.

Receptacle 24 includes a plurality of walls 32.

In the first embodiment of the invention shown in the , the reader 14 is arranged in one of the walls 32 of the receptacle 14.

The size of the reader 14 is thus greatly reduced.

In a second embodiment of the invention shown in the , the control system 10 further comprises a box 34.

The box 34 is suitable for being placed in the receptacle 24 in a removable manner.

The term “removable” is understood to mean which can be moved or removed from the receptacle 24 without it being necessary to remove any fastening means between the box 34 and the receptacle 24.

The box 34 in particular has a maximum transverse dimension of between 20 and 100 cm.

Reader 14 is placed in box 34.

The box 34 makes it easy to implement the invention in a receptacle 24 possibly already installed.

According to an exemplary embodiment, as visible in the , the control system 10 comprises an independent computer further comprising at least one processor 50 and a memory 52. In this case, the aforementioned modules are at least partially in the form of programmable logic circuits of the FPGA type (from the English “Field-Programmable Gate Array”) and/or software stored in the memory 52 of the computer and executable by the processor 50 thereof.

The control system 10 has been described above with a single reader 14 but it is understood that the control system 10 alternatively comprises a plurality of readers 14, in particular in the case of a receptacle 24 of large size.

In the first embodiment, two readers 14 are for example each arranged on an opposite wall 32 .

In the second embodiment, the control system 10 comprises for example a plurality of boxes 34.

In a variant, the control system 10 has no receptacle 24, the or each reader 14 controlling the packaging 12 located nearby.

The use of the control system 10 will now be described for a receptacle 24 containing a single packaging 12. However, those skilled in the art will understand that the control method according to the invention applies in a similar and advantageous manner to a plurality packaging 12.

Initially, package 12 is disposed in receptacle 24 in the sealed configuration.

The electronic tag 30 associated with the packaging 12 is therefore intact.

The reader 14 periodically reads the signals provided by this electronic tag 30.

The reader 14 reads in particular the signal representative of the associated product and the signal representative of the configuration in which the packaging 12 is located.

The reader 14 transmits these signals to the processing module 16.

From the signals received, the processing module 16 identifies the product and detects that the packaging 12 is in the sealed configuration.

Then, the user takes the packaging 12 out of the receptacle 24 and opens the packaging 12 for the first time.

By separating the dispensing head 28 and the container 26, the electronic tag 30 partially breaks, as can be seen on the .

The user may use the product then replace the packaging 12 in the receptacle 24.

The reader 14 continues to periodically read the signals supplied by this electronic tag 30 and to transmit these signals to the processing module 16.

From the signals received, the processing module 16 then identifies that the packaging 12 is in the unsealed configuration.

The processing module 16 then deduces the opening date of the packaging 12.

Then, the processing module regularly compares this opening date with the current date and determines the duration of opening of the packaging 12.

Advantageously, the processing module 16 also compares this duration of opening of the packaging 12 with the predetermined maximum opening duration associated with the product.

The communication module 18 sends the configuration and the comparison with respect to the predetermined maximum opening time to the database 19.

The user optionally consults the database 19 by means of a mobile terminal.

When the opening time of the packaging 12 is greater than the predetermined maximum opening time, the alert module 20 generates an alert intended for the user.

The user can then remove the packaging 12 from the receptacle and possibly replace it with a new packaging 12.

The user thus has precise knowledge of the duration of opening of the packaging 12 and thus not throwing it away prematurely or using it too late and preserving his health.

An example of implementation of the control method according to the invention will now be described.

The receptacle 24 initially comprises four products, subsequently called product A, product B, product C and product D.

Product A comprises only a conventional RFID tag and therefore has no electronic tag 30 according to the invention. The RFID tag includes, for example, information identifying product A.

Product B comprises an electronic tag 30 and in particular a frangible tag.

The product C comprises an electronic tag 30 and in particular a non-frangible tag, capable of providing a different identifier depending on the configuration of the associated packaging 12.

The product D comprises an electronic tag 30 and in particular a tag capable of emitting a signal only when the associated packaging 12 is in the sealed configuration.

The packaging 12 associated with the products A and B are for example in the sealed configuration and the packaging 12 associated with the products C and D are for example in the unsealed configuration.

During a first iteration, the reader 14 sends a read signal, for example of the RFID type.

This reading takes place at a time reading t0.

This reading is triggered automatically or from an order sent by the user.

The labels of the different packaging associated with the products A, B, C and D send back a signal in response to the prompting of the reader 14.

The signals are received and processed by the processing module 16.

In particular, the processing module 16 records in the database 19 the information associated with the various signals and the associated reading time t0.

In particular, if the product identifier is not already present in the database 19, the processing module 16 adds this new identifier and the associated product in the database 19 as well as the corresponding associated configuration and the time of reading t0.

If the product identifier is already present in the database 19, the processing module 16 updates the corresponding associated configuration and the reading time t0.

For example, if the product B has just been placed in the receptacle 24, the associated identifier is not present in the database 19. The processing module 19 adds this identifier and associates the associated configuration, here sealed , and the reading time t0.

The products A, C and D being already present in the receptacle 24 previously, the database 19 already includes their identifier.

Since product A is associated with a simple RFID tag, the signal received does not include information on the configuration of the packaging. Thus, it is not possible to detect the configuration change. However, the database 19 includes its date of placement in the receptacle 24. The user can thus consult this date and compare it to the current date to get an idea of the state of the product.

Products C and D were already in the unsealed configuration.

Thus, the processing module 16 only updates the reading date t0 and deduces therefrom the new duration of opening of the associated packaging 12.

The processing module 16 also compares the opening time of the two packages 12 with the predetermined maximum open time associated with the products C and D.

If, for example, the opening time of the packaging 12 of the product C is greater than the predetermined maximum opening time for the product C, the alert module 20 generates an alert intended for the user indicating that the product C is no longer usable.

If product C has been discarded, the user deletes product C from the database 19.

The processing module 16 also compares, for each packaging 12, the expiry date of the associated product with the current date.

Thus, if for example, the product D has an expiry date prior to the current date, the alert module 20 generates an alert intended for the user indicating that the product D is no longer usable.

Similarly, if product D has been discarded, the user deletes product D from the database 19.

Then, during a second iteration, the reader 14 sends a new read signal.

This reading takes place at a time reading t1.

The labels of the different packaging associated with the products A, B, C and D send a signal back to the request of the reader 14.

The signals are received and processed by the processing module 16.

In particular, the processing module 16 records in the database 19 the information associated with the various signals and the associated reading time t1.

The signal received from packaging 12 associated with product B includes information that packaging 12 is in the unsealed configuration.

The processing module 16 then detects the configuration change.

The opening duration date is for example determined from the recorded reading time t1 associated with the change in configuration of packaging 12 of product B.

Alternatively, in a more conservative manner, the opening date is determined from the reading time t0 recorded directly before associated with the change in configuration of packaging 12 of product B.

The processing module 16 therefore determines an opening duration of the product B from this opening date t1 or t0.

The process then includes new iterations similar to those described above in order to follow the opening times of the different products.
