Description

BACKGROUND OF THE INVENTION The invention relates to the field of connected objects, and in particular a connected bottle. More particularly, the invention relates to an electronic system for monitoring the consumption of a fluid product contained in a container provided with a pump, and an associated dispenser and container.

The Internet is evolving in relation to the initial Internet system, which until now had been able to connect mainly fixed and mobile digital terminals such as computers, smartphones or digital tablets. The Internet of Things, also referred to as IoT in English for Internet of Things, represents the extension of the Internet to things and places in the physical world. While the Internet usually does not extend beyond the electronic world, the connected Internet of Things represents the exchange of information and data from devices in the real world to the Internet communication network.

Many different applications result from the Internet of Things, such as: - water bottles that measure the flow of water out of the bottle and therefore drunk by the user, and transmitting the information to servers computer who transmit it to an application on a smartphone to inform the user of its consumption and in particular to alert him when he is late on the ideal amount of water that he must drink during the day; - Certain lighting devices, particularly bulbs, provided with communication means making it possible to control them from a smartphone, for example to control the light intensity according to a fine analysis of the behavior of the user, or bracelets connected with sensors for example to analyze the metabolism of the user to detect its phases of deep and light sleep; - Connected forks that track and monitor eating habits, including how long it took to eat, how many bites were taken per minute, and the intervals between bites, and then forwarding the data to a computer server for analysis or an application for Smartphone integrating a coaching program helping the user to analyze and improve his eating habits; electronic devices that can be connected to the water meters, measuring users' water consumption in real time, the devices including in particular a central box analyzing the data and transmitting them to a smartphone application from which it is possible to detect possible leaks (abnormal consumption) or simply to visualize and analyze one's own consumption; sensors grafting on manhole plates making it possible to detect when a plate is opened or closed, the information being transmitted on servers and made accessible to the user (via the municipal services for example) which can detect a abnormal state linked for example to an intrusion or a plate remained open.

To allow communication of computer data to or from these objects, there are several known wireless communication technologies such as LAN (Local Area Network) technologies, cellular type technologies, RFID type technologies (radio frequency identification).

Wifi and Bluetooth are technologies using a local network, that is to say, LAN-type technologies. Wi-Fi can carry large amounts of data over distances of several meters or even tens of meters. Bluetooth also makes it possible to carry large amounts of data, but for shorter distances. Both technologies, like LAN technologies, require a significant power supply. The objects using them must therefore be equipped with bulky, heavy, bulky batteries, which must be regularly recharged. They do not allow data to be transmitted over long distances without relay points.

Cellular technologies are used by smartphones and some USB keys to communicate on the network. We talk about 3G, 4G or 5G. They make it possible to transit large amounts of data over long distances. However, the amount of energy required is important, the devices must be equipped with bulky and bulky rechargeable batteries. The cost of deploying this type of network is also very important, the cost for the end user is significant.

RFID technology makes it possible to transmit information from a chip (often passive) connected to an antenna to a transceiver terminal.

This technology requires, however, to have a suitable transceiver to read the information issued by the chip. It may be a smartphone or a specific terminal, such as some motorway toll terminals or anti-theft terminals positioned at the exit of some stores. In addition, the information can generally be transmitted between the chip and the transceiver only over short distances.

This technology does not require that the chip is connected to a battery (passive configuration). But, as a result, the nature of the information to be transmitted is by nature limited to what has been configured by the manufacturer from the start in the chip. Without equipping the RFID chip with a battery, it is also not possible to communicate with a reception terminal over long distances since in this configuration, the RFID device uses the energy of the transmission-reception terminal which queries to return the preconfigured information.

Pairing the RFID device with a battery (active configuration) may allow communication over greater distances (several tens of meters) but still requires a specially configured, adapted receiving terminal.

In general, RFID technology is commonly used passively for purposes of identifying the object on which the chip is embedded and not as a means of communicating dynamic information over a network.

It is in particular known RFID chip systems that can be integrated on bottles, ideally concealed under the label, and to ensure communication of the information contained in the chip with external reception terminals, in particular to monitor the logistic movements of the bottle during storage and shipping.

It is also known devices for detecting the opening of a bottle of champagne and transmit the information to a nearby receiving terminal with an RFID chip.

It is also known from documents FR 2 911421, FR 2 876 200, FR 2 864 040, FR 2 964 035 and FR 2 832 134, fluid dispensing members comprising an identification unit that can be an electronic tag having a antenna and a memory retaining an identification code, the communication means used in these systems being generally RFID means.

Packaging of perfumery, cosmetics or household products provided with a spraying system are extremely common in the trade due in particular to their simplicity of use for the consumer. These packages can be aerosols, that is to say under pressure, or not aerosols as for perfume bottles.

Most cosmetic packaging can be opaque, making it impossible to directly and visually observe the level of product available in the package. The evaluation of the weight of the product by a normal user without a measuring tool also makes it impossible to deduce precisely the level of use of the product. Due to the small quantities in question, this information can not usually be obtained by shaking the product so as to move its contents.

In general, even in cases where the container is semi-opaque or transparent, as for most perfume bottles and some cosmetic or household products, blind people have no way of accurately assessing the quantity of remaining product. Blind people have no way to accurately anticipate the end of life of the product and are forced to wait for the total exhaustion of the product to see the need to resupply.

There are spray metering systems for aerosol devices. They are mainly related to medical uses for particular the administration of doses of drugs contained in aerosol flasks. These counting mechanisms are broken down into two categories: mechanical solutions having a display device (rotating disc, needle, etc.) which is incremented at each depression of the container, and electronic solutions making it possible to display the number remaining doses on an LCD display or the like; these are based either on the use of pressure sensors detecting the air outlet or on the activation of a switch (type of valve) which changes position under the effect of the gas outlet.

It is further known from US 8 539 945 a solution detecting the level of pressure exerted by the user on the container to deduce the trigger or not the nebulizing device. This solution also makes it possible to record on an on-board memory the number, the date and the time of the spraying, so as to be able to download them on a conventional external terminal with or without wire. The downloading of consumer information requires deliberate action on the part of the user, which is constraining, complicated, and may even be problematic in the event of forgetting the user in the context of medical applications.

It is also known from WO 2003/092576 alert systems triggering when a patient must take a new dose of medication, according to the pre-configured dosage. A clock and spray detection mechanism triggers the alarm when the drug has not been taken for a long time. The warning system is here integrated into the container which makes it expensive to produce, cumbersome and therefore proposes a solution that is not very flexible.

It is also known from US 5 482 030 a spray counting mechanism operating on non-aerosol devices. This system is mechanical (display disk) and therefore needs to be able to read the information represented by the disk. Since the system is mechanical and the disc visible from the outside, the disc is subject to fouling. Finally, this type of mechanical system does not allow to keep a history or transmit or analyze the usage data.

It is moreover described in US Re 34847 a system for counting the number of times an aerosol containing perfume has been used (notched wheel). An electronic mechanism makes it possible to compare the value of the counter with a predetermined value so as to visually alert the user when the product is almost empty.

This system is designed to operate only with aerosols and is not applicable to a pump spray system. It also does not allow to track consumption remotely or to keep a precise history of consumption. The visual reading of the alert is finally not flexible since it is integrated into the device and is therefore limited to certain preconfigured scenarios.

Some of these systems mentioned above are equipped with a display indicating the amount of product remaining in the container. Others allow to save the history of the spraying and to download it on an external terminal like Smartphone, computer or tablet. However, all these devices are: - designed for use with aerosols and therefore unsuitable for use on a non-pressurized bottle such as those usually containing perfume or cosmetics; - Or purely mechanical and do not analyze store and communicate the information to the user to possibly allow him to track his consumption at a distance and / or anticipate the end of the product; these solutions are therefore not flexible, unnecessary for example in the case of blind people, and their mechanical nature makes them vulnerable to fouling or blockage.

It is currently impossible for a third party, or even for the user himself, to know accurately, automatically and reliably, the consumption of a fluid product contained in a container equipped with a spraying system comprising a pump.

OBJECT AND SUMMARY OF THE INVENTION The purpose of the invention is to overcome the drawbacks mentioned above by providing an electronic system for communicating the state of consumption of a fluid product in a container such as a spray bottle, and particularly of forming a container equipped with a fluid dispenser, such as a perfume sprayer, capable of communicating in real time to a remote server the consumption of fluid product by the user, in particular to signal the impending rupture of product fluid in the container or even allow a supplier of the fluid product to address commercial offers before the container is empty.

An object of the invention proposes an autonomous electronic system for monitoring the consumption of a fluid product contained in a receptacle equipped with a pump, the system comprising a power supply unit and a consumption detection unit coupled to the feed unit and configured to detect an event relating to a change in the amount of fluid remaining in the container.

According to a characteristic of the invention, the system further comprises a data transmission antenna and a data transmission control module for transmitting a signal based on the data supplied by said detection unit, the control means and the control unit. antenna being configured to transmit data over a wireless communication network.

By autonomous means an electronic system not dependent on an external power supply network to which it must be connected to operate. The power supply unit can for example comprise a battery pack or a piezoelectric module making it possible to supply enough energy to determine the state of consumption and to process the information, that is to say to compare it with a threshold, and / or store it and / or transmit information via the transmission antenna.

By communication or telecommunications network is meant, as defined in the literature, a network of arcs (telecommunications links) and nodes (switches, routers ...), set up so that messages can be transmitted from one end of the network to the other across multiple links. Bluetooth or RFID communication technologies are therefore not alone, not communication networks.

The transmission by a wireless communication network of the consumption data to remote servers makes it possible, firstly, to have a high computation capacity on the server side, for example to finely analyze the consumption of the user by crossing it with other data, secondly, to provide the user with accurate statistics with an exhaustive history stored on the servers, thirdly, to render this information on an unlimited number of devices (computer, smartphone, tablet, connected watch, etc.) and thus allow a user to access the information in a mobility situation, and finally, to alert the user according to certain predefined scenarios analyzed on the server side. This finally has the advantage of allowing third parties to access this information if necessary.

The consumption data can thus be compared for example with an average daily consumption and the total capacity of the container to deduce the number of days of use remaining. This makes it possible to send the information of the remaining product level to a digital terminal such as a smartphone. This also has the advantage of being able to use the audio device of these terminals and to allow for example blind people to be alerted by a hearing process very accurately on the state of their consumption. This allows them to have a much more complete information on an audio device that would be embedded on the container. Such an embedded device would also be bulky, energy-consuming, expensive to produce because having to integrate at least a relatively powerful processor, a rechargeable battery and speakers.

According to a first aspect of the electronic system for monitoring the consumption of a fluid product contained in a receptacle provided with a pump, the supply unit may comprise a battery. The use of a battery pack as a power supply unit makes the container with the electronic system autonomous and portable and stores enough energy to transmit several times before the container is empty. the network of communication and to avoid the use of a mechanical part, as for a piezoelectric, risking to clog up with the time and to be defective with the unit of feeding.

The battery is preferably sized to last for a time longer than the average time for the container to be emptied of its contents by a user with an average use of the product.

According to a second aspect of the electronic system for monitoring the consumption of a fluid product contained in a container provided with a pump, the electronic system may comprise a data storage memory. The recording of the data, in particular with each spraying, makes it possible to keep the usage information in memory without necessarily transmitting it immediately. This makes it possible to group the data items together and thus to save the battery, thus prolonging its lifetime.

The storage also makes it possible to constitute a history of use that can be transmitted later to a remote computer server, or to store quantity thresholds for triggering a product failure approach warning alert.

According to a third aspect of the electronic system for monitoring the consumption of a fluid product contained in a receptacle provided with a pump, the data transmission control means and the antenna are configured to respectively form and transmit a transmission signal. data having a frequency in the frequency band of a low bit rate wireless communication network (LPWAN).

Low-power wide-area network (LPWAN) or low-throughput network (LTN) technologies are low-bandwidth communication networks that transmit small amounts of data over long distances. The amount of energy required to send these small data packets over the network is very small. The use of such a wireless communication network thus makes it possible to use a small battery as a battery for powering the electronic monitoring system, thereby improving the integration power of the electronic system in or on a container, by making it lighter, more discreet and less bulky, and this while avoiding having to recharge or change the battery in question. The use of such a wireless communication network also offers the advantage of being able to carry data over long distances, that is to say of the order of several kilometers or even ten kilometers, and of have a very low network deployment cost compared to cellular networks since a transmission base station can serve thousands of devices simultaneously given the low data rate per transmission. Because of the low infrastructure cost of these LPWAN networks, the cost of use for the end user is advantageously lower than on a cellular telecommunication network.

The electronic system according to the invention thus makes it possible to produce a container provided with a dispenser with a pump which is connected, that is to say which makes it possible to transmit the information relating to the consumption of the fluid product to a server remote via an LPWAN communication network. A user can then access the information on the server using a conventional terminal such as a smartphone and be alerted and the amount of available product.

According to a fourth aspect of the electronic system for monitoring the consumption of a fluid contained in a container provided with a pump, the system may further comprise a processing unit configured to determine the amount of fluid remaining in the container after each actuation of the pump from the initially reported information relating to the amount of fluid initially contained in the container and the amount of fluid produced at each actuation of the pump.

In a variant, the system may be devoid of a processing unit, all the analysis being deported to the server side. The system is then content to store the information relating to the actuation events, such as spraying, in the memory and send the information to the server at regular intervals. It is therefore server side that we have the maximum number of sprays that can be made and that we deduce the number of theoretical spraying remaining.

According to a fifth aspect of the electronic system for monitoring the consumption of a fluid product contained in a receptacle equipped with a pump, the detection unit may comprise an event detection module, a first part intended to be fixed on a movable portion of a pump actuating means and a second portion separate from the first portion and being mounted on a stationary portion of the container or pump, the first portion and the second portion forming a switch coupled to the module; event detection circuit capable of producing an electrical event detection signal when the first and second portions of the connector come into contact.

Preferably, the second portion of the connector comprises at least two separate conductive elements intended to be mounted at at least two different levels to cover at least two different positions of the stroke of the movable portion of the pump actuating means.

The second part may thus be composed of one or more conductive elements which successively come into contact with the first part as the pump descends, thus making it possible to detect incomplete sprays (in that the first part does not reach the conductive element of the second farthest part). Incomplete means sprays that have not ejected all the fluid in the pump.

Alternatively, the consumption detection unit may comprise a level gauge configured to detect a level change and / or measure the level of fluid remaining in the container.

The level gauge may be configured to have at least one member mounted on a pump rod slidable along the stem to indicate the level of liquid remaining in the bottle. The measurement can be made for example optically or by calculating a travel time between the sliding element and the top of the bottle.

Another object of the invention proposes a device for dispensing a liquid product provided with a pump and intended to be mounted on a container such as a bottle, comprising a conduit for conveying the liquid product, means for dispensing actuation capable of generating a flow of liquid product in the conveying conduit, fixing means for fixing the device to the container, and an electronic monitoring system as defined above mounted on a portion in communication with said pump.

According to one aspect of the dispensing device, the actuating means comprise a push button, the first part of the detection unit is housed in the push button and the second part of the detection unit is integrated in the fixing means.

Another object of the invention provides a container comprising a device for dispensing a liquid product provided with a pump intended to be mounted on a container as defined above.

The container may be a cosmetic bottle or a perfume bottle.

Detailed description of embodiments

Figure la shows an exploded perspective view of a spray bottle according to a first embodiment of the invention.

The bottle 1 is shaped to contain a fluid product such as liquid perfume and comprises a neck, also called screed, shaped to receive a dispensing device 3 of liquid product such as a spray or spray.

The sprayer 3 comprises a vaporization pump 4 provided in particular with a rod 5, or stem, capable of being immersed in the fluid contained in the bottle, with a push button 6 fixed to one end of the rod 5 opposite to the end intended to be immersed in the fluid contained in the vial 1, and a lower portion 7 adapted to be fixed on the neck of the vial 1.

The lower part 7 and the push button 6 define a vaporization chamber adapted to contain a portion of air when the push button 6 is in a rest position, that is to say not engaged. The air of the vaporization chamber is expelled from the chamber to a vaporization orifice 8 each time the pushbutton 6 is actuated. And the air is refilled with the vaporization chamber each time the pushbutton 6 is released.

The push button 6 is mounted on said end of the rod 5 opposite the end immersed in the liquid product of the bottle so as to have this end disposed between the vaporization chamber and the vaporization orifice 8. Thus the air expelled from the vaporization chamber to the spray orifice 8 passes above the rod 5 which generates a depression at the top of the rod and causes by Venturi effect a displacement of the liquid product to the top of the rod, and the liquid delivered at the top of the stem is then sprayed by the breath of the air expelled from the vaporization chamber to the vaporization orifice 8.

The bottle 1 further comprises an electronic system 10 for monitoring the consumption of the fluid contained in the bottle 1.

The detection unit 20 comprises an event detection module 16 mounted on the electronic card 12 and a first movable contactor 17 secured to the push button 6 and a second fixed contactor 18 mounted in the neck or the lower part. 7 of the sprayer 3. The first and second contactors 17 and 18 are connected to the event detection module 16 and form a detection switch operating mechanism capable of closing the detection circuit and triggering an event signal each time the push button 6 is actuated, as illustrated in FIG.

The data transmitted by the event detection module 16 are processed by the processing unit 14 to determine how much fluid remains in the bottle 1 before being stored in the memory 15.

In a more energy-efficient variant, the electronic card may be devoid of processing unit 14, and the data from the consumption detection unit 20 directly stored in the memory 15, or the processing unit may be a processor simply controlling the storage in memory 15 of the information from the detection unit 20 and accessing the memory 15 to deliver the information to be transmitted to the antenna 13. In these two cases, the determination of the remaining quantity is carried out from the side of the server, once the information has been transmitted.

In yet another variant, the system may be free of processing unit and memory, and include a processor controlling transmission via the antenna 13 of a push button actuation signal to each event detected by the unit. detection 20.

The electronic card 12 further comprises a data transmission control module 19 configured to control a transmission of computer data stored in the electronic memory 15 by the antenna 13.

The data transmission control module 19 and the antenna 13 are configured to respectively form and transmit a data signal having a frequency in the frequency band of a low-speed wireless communication network (LPWAN) for example a frequency band centered around a value of the order of 800 MHz or 400 MHz, in particular an 868 MHz or 902 MHz frequency band. The use of the LPWAN or LTN network to transmit the stored data makes it possible to have as a battery 11, a small battery which can be discreetly integrated into the bottle 1 without a recharge or a change of the battery is necessary before the bottle is emptied of its contents by a user. The use of such a wireless communication network also has the advantage of being able to route data over long distances, that is to say of the order of several kilometers or even several tens of kilometers.
