Waste collection container Field of invention
[0001] The present invention relates to the field of waste collection containers, in particular containers for voluntary waste contribution accessible to a group of users, for example in a public place. State of the art
[0002] The technology of waste collection containers, particularly those used in public places, is already known. Waste collection containers are devices widely used for urban waste management. Traditionally, these containers are characterized by a standard design, often consisting of a cylindrical, rectangular or other shaped body, with one or more openings for depositing waste, as well as means for emptying it. Typically, these containers are as defined in standard EN 13071:2019, in standard NF_EN 840:2020 or in standard NF EN 15132:2006.
[0003] In conventional containers, users are often faced with uncertainty about the remaining capacity of the container. However, when a user arrives at a full container, it is rare for this user to leave with their waste in the direction of another container. This situation frequently leads to excessive waste deposits inside the container, or even to the container overflowing, or to an accumulation of waste next to the container, causing hygiene, aesthetic and waste management problems more generally. In addition, an excessive accumulation of waste in a container can lead to hindering its proper functioning, for example by blocking an opening system of an emptying hatch inside the container or by preventing the closing of a waste introduction hatch intended to prevent the release of odors or the entry of insects.This results in inefficient use of waste collection infrastructure and additional costs associated with inadequate management.
[0004] In order to overcome this drawback and improve overall waste management, the present invention aims to provide a waste collection container allowing a user to adapt his use of the waste collection containers to the storage availability of these containers.
[0005] For this purpose, the invention relates to a filling limit detection device for a waste collection container. It is therefore understood that the filling limit detection device is intended to be installed on a waste collection container. The device comprises at least one filling level detector configured to measure a container filling level, intended to be placed inside a main body of the waste collection container, and at least one filling level indicator capable of being visible from outside the waste collection container. The filling level indicator is configured to display information indicating that the filling limit of the waste collection container has been reached when the filling level is greater than or equal to a predefined filling level.
[0006] The fill limit detection device can be installed on existing and / or existing containers. For example, its installation can be carried out using a retrofit kit, thus facilitating adaptation to existing installations.
[0007] The fill limit detection device also comprises at least one control module configured to receive container fill level information from the fill level detector and to modify a display state of the fill level indicator depending on the fill level information.
[0008] According to preferred embodiments, the filling limit detection device according to the invention may further comprise the following features, implemented separately or in each of their technically operative combinations.
[0009] Preferably, the filling limit detection device comprises a brightness sensor intended to be placed outside a main body of a waste collection container, configured to measure ambient brightness. The control module is in this case configured to modify the display state of the filling level indicator according to ambient brightness information.
[0010] Preferably, the fill level indicator is a light indicator. For example, it may comprise at least one light-emitting diode.
[0011] Advantageously, the control module is configured to modify a light intensity of the fill level indicator depending on the ambient brightness information.
[0012] The invention also relates to a waste collection container comprising a main body forming a waste collection volume and at least one opening for introducing waste into the main body. In addition, the container comprises a filling limit detection device according to the invention. The filling limit detection device comprises at least one filling level detector configured to measure a container filling level placed inside the main body, and at least one filling level indicator visible from outside the container. The filling level indicator is configured to display information indicating that the container filling limit has been reached when the filling level is greater than or equal to a predefined filling level.
[0013] The container also comprises at least one control module configured to receive container fill level information from the fill level detector and to modify a display state of the fill level indicator depending on the fill level information.
[0014] Thus, the invention will allow users to easily know the filling status, full or not full, of the container, in particular remotely, thus encouraging them to adopt more responsible behavior by avoiding depositing waste when the container has reached a filling capacity determined as being the maximum filling capacity of the container. In addition, the invention encourages users to move towards a container that is not full, thus promoting more efficient use of collection infrastructure.
[0015] According to preferred embodiments, the container according to the invention may further comprise the following features, implemented separately or in each of their technically operative combinations.
[0016] Preferably, the waste collection container comprises a brightness sensor placed outside the main body, configured to measure ambient brightness. The control module is in this case configured to modify the display state of the fill level indicator depending on ambient brightness information.
[0017] Advantageously, the waste collection container comprises a shutter of the waste introduction opening movable between a closed position closing the waste introduction opening and an open position in which the waste introduction opening is accessible, and a member for controlling access to the waste collection volume. Said member for controlling access to the waste collection volume is configured to lock the shutter in the closed position when the filling level is greater than or equal to the predefined level.
[0018] Advantageously, the waste collection container comprises a remote communication system configured to send information about reaching the filling limit to a waste collection organization when the filling level is greater than or equal to the predefined filling level.
[0019] According to various examples, the filling level detector is selected from an ultrasonic detector, a laser detector or an infrared detector.
[0020] Preferably, the fill level indicator is a light indicator. For example, it may comprise at least one light-emitting diode.
[0021] Advantageously, the control module is configured to modify a light intensity of the fill level indicator depending on the ambient brightness information.
[0022] According to one embodiment, the filling limit detection device comprises at least two filling level detectors, for example at least three filling level detectors.
[0023] Advantageously, the filling limit detection device comprises at least two filling level indicators oriented in different directions. The indicator display can thus be visible from different directions.
[0024] According to an advantageous feature, the waste collection container comprises a battery box capable of providing electrical power to the waste collection container.
[0025] The invention also relates to a method for warning of the filling level of a waste collection container according to the invention. The warning method comprises the steps of: measuring the filling level of the container by the level detector, comparing the filling level with the predefined filling level, and displaying the information of reaching the filling limit of the container by the filling level indicator if the filling level is greater than or equal to the predefined filling level.
[0026] According to preferred embodiments, the method according to the invention further comprises the following optional features, taken alone or in combination.
[0027] Advantageously, the warning method further comprises the following steps: measuring the ambient brightness, comparing the measured ambient brightness with at least one predefined ambient brightness value, and changing the display state of the fill level indicator depending on a result of the comparison between the measured ambient brightness and the predefined ambient brightness value.
[0028] Advantageously, the step of comparing the ambient brightness and the step of modifying the display state of the filling level indicator as a function of ambient brightness information comprise one or more of the following sub-steps:sub-step of comparing the measured ambient brightness to a first predefined threshold value:if the measured ambient brightness is greater than or equal to the first predefined threshold value, the filling level indicator displays the information of reaching the filling limit with the light intensity equal to 100% of a predefined light intensity;andif the measured ambient brightness is lower than the first predefined threshold value, sub-step of comparing the measured ambient brightness to a second predefined threshold value lower than the first threshold value:if the measured ambient brightness is lower than or equal to the second predefined threshold value, the filling level indicator is inactive, andif the measured ambient brightness is lower than the first predefined threshold value and is higher than the second predefined threshold value, the filling level indicator displays the information of reaching the filling limit with the light intensity lower than 100%, for example lower than 90%, typically between 30% and 70%, of the predefined light intensity.; Brief description of the figures

[0036] Different figures and elements within a figure are not necessarily represented on the same scale. In all figures, identical elements bear the same numerical reference.
[0037] The terminology used in this description should not be interpreted in any way as limiting or restrictive, simply because it is used in conjunction with a detailed description of certain embodiments of the invention.
[0038] Conventionally, the waste collection containers of the present invention comply with the EN 13071:2019 standard, the NF_EN 840:2020 standard or the NF EN 15132:2006 standard. The waste collection containers of the present invention may be intended to receive any type of waste such as, for example, household waste, paper, cardboard, plastic, metal and / or glass. A semi-buried waste collection container 100 (hereinafter referred to as "container 100") according to a first embodiment is shown, comprising a main body 110 forming a waste collection volume and at least one opening 112 for introducing waste into the main body 110. In the, only a portion of the main body 110, located above the ground, is shown. In this non-limiting example illustrated in the, the container 100 is provided with a shutter 114 for the waste introduction opening 112.This shutter 114 may be a lid or a rotating drum. This opening 112 is closed when the shutter 114 is in a closed position and becomes accessible when the lid or the drum is open. For example, the shutter 114 may be sliding, pivoting, folding, or have any other suitable mechanism. In a variant, rather than being provided with a shutter, the container 100 may be equipped with a rubber flap, for example composed of rubber portions (or petals) arranged around the opening.
[0039] The container 100 comprises a filling limit detection device. The filling limit detection device comprises a filling level detector 120 which measures a filling level h of the container with waste. The level detector 120 emits mechanical and / or electromagnetic waves to measure the filling level h of the container. In non-limiting examples, the filling level detector 120 may be selected from an ultrasonic detector, a laser detector or an infrared detector.
[0040] The fill level detector 120 is placed inside the main body 110, preferably at the top and center of the main body 110, near the waste introduction opening 112, in order to measure the level where the waste is likely to be highest, thus ensuring more efficient measurement.
[0041] The detector 120 may be attached to a wall of the main body 110 by a conventional fastening means (screwing, riveting, etc.). Alternatively, the detector 120 may be mounted on a specific support inside the container.
[0042] The container filling limit detection device 100 may be provided with several filling level detectors 120. In a non-limiting example, two detectors 120 are positioned separately at both ends of a diameter of the cylinder-shaped main body 110. In another non-limiting example, more than three detectors 120 are arranged separately at various locations to measure the filling level in different areas of the waste collection volume, allowing a more precise definition of the filling of the container.
[0043] The filling limit detection device of the container 100 is also provided with a filling level indicator 140. This indicator 140 is visible from outside the container, thus allowing the user to consult it without looking inside the container 100. It is for example mounted through a through-hole provided on a wall of the container.
[0044] When the filling level h reaches or exceeds a predefined filling level h p , indicator 140 displays information that the container fill limit has been reached. Otherwise, indicator 140 displays a default state.
[0045] The container filling limit detection device 100 also comprises at least one control module (not shown). The control module receives container filling level information sent by the filling level detector 120. Depending on the filling level, the control module modifies the display of the indicator 140, as previously described.
[0046] The control module is preferably placed inside the main body 110 of the container 100.
[0047] Advantageously, the predefined filling level h p is configurable by a waste collection manager. As a non-exhaustive example, the predefined filling level h ppeut correspondre à un niveau auquel un volume de déchets atteint une capacité totale du volume de collecte de déchet du conteneur 100, ou correspondre à un niveau où un volume de déchet inférieur à 100%, par exemple, égale à 80%, de la capacité totale du volume de collecte de déchet du conteneur. Cette seconde possibilité est intéressante car elle permet de conserver un volume de stockage de réserve dans le cas où un utilisateur souhaiterait tout de même introduire des déchets dans le conteneur malgré l’affichage d’une information de remplissage maximal atteint.
[0048] Preferably, the predefined filling level h pcan be changed at any time when using the waste container 100. Generally, the predefined filling level is entered into the control module by the waste collection manager. Preferably, the predefined filling level h p is defined based on the frequency of waste collection and / or the use of the container.
[0049] Preferably, the indicator 140 is luminous, and advantageously visible even from a distance, allowing the user to consult it from a distance. This prevents the user from moving with waste to the container 100 without realizing that it is full, thus risking leaving waste on the ground, because he does not want to turn back to find another container. Another advantage of the indicator 140 is to optimize the frequency of collection by a collection organization of the container 100 when the latter is full.
[0050] For example, the indicator 140 comprises at least one light-emitting diode (LED). The LED of the indicator 140 may illuminate red to display information that the container has reached its fill limit. The LED may illuminate green or remain off to display the default state of the indicator 140 when the fill limit has not been reached.
[0051] Advantageously, the indicator 140 comprises an LED screen capable of displaying numbers, text or other symbols. Advantageously, this display of the indicator 140 can represent a filling rate equivalent to h / h p , whether by a number, text, percentage gauge, or any other form known to those skilled in the art. This provides users with more detailed information.
[0052] Preferably, the container 100 may be equipped with a plurality of indicators 140 oriented in different directions, thereby allowing the indicator display to be visible from different directions.
[0053] Advantageously, the container 100 is provided with a brightness sensor (not shown) placed outside the main body 110, configured to measure an ambient brightness l a . Therefore, the control module is also configured to modify a display state of the indicator 140 depending on the measured ambient brightness.
[0054] Preferably, the fill level indicator 140 switches between a performance mode and an economy mode. In performance mode, the light intensity of the indicator 140 is, for example, equal to 100% of a predefined light intensity, allowing the indicator 140 to be visible during a daylight day. In economy mode, the light intensity of the indicator 140 is reduced compared to that in performance mode, for example, less than 90% of the predefined light intensity, typically between 30% and 70% of the predefined light intensity. This economy mode is optional and makes it possible to limit energy consumption when ambient light is reduced, for example during the night, at dawn, at dusk and in cloudy weather. A warning method will be described below, by way of example.
[0055] According to an advantageous variant, and in the event of the presence of a shutter 114, an access control member (not shown) to the waste collection volume can be configured to lock the shutter 114 in the closed position once the filling level h reaches or exceeds the predefined filling level h p This is to prevent the container from overflowing by preventing a user from forcing access to the waste container when it is already full.
[0056] Advantageously, the access control member comprises a receiver configured to receive a locking control signal sent by the control module as soon as the filling level h reaches the predefined filling level h pThe access control member also includes a locking system, such as a piston bolt lock, a triangular key lock, etc., to hold the shutter 114 in the closed position upon receipt of the locking control signal by the receiver.
[0057] According to a preferred variant, the container 100 comprises a remote communication system (not shown) configured to transmit the information that the filling limit has been reached to the waste collection organization as soon as the filling level h reaches the predefined filling level h p This is to inform the manager of the need to collect waste from the container once it is full. This may involve sending a radio wave signal from the container to a wave receiver at the container manager's premises.
[0058] Preferably, the remote communication system transmits to the waste collection organization the filling level h measured by the filling level detector 120 or the filling rate at regular intervals. This allows the manager to monitor the filling status of the container proactively, thus facilitating the management of waste collection.
[0059] Advantageously, the container 100 is equipped with a battery box (not shown) capable of providing the electrical power necessary for the operation of the container 100. For example, the battery box powers the detector 120, the indicator 140, the control module, the brightness sensor if applicable, as well as the remote communication system if present.
[0060] The invention has been described in the preferred configuration of an above-ground waste collection container, as illustrated in the. It is however possible, without departing from the scope of the invention, to adapt the invention to any other configuration of waste collection container, such as, for example, underground waste collection containers.
[0061] Figures 2 to 3 illustrate an example of an underground waste collection container 100. This underground container is particularly suitable for urban environments or spaces where aesthetics and space occupation are major concerns.
[0062] The container 100 comprises a main body 110. A lower portion (not shown) of the main body 110 is located underground, thereby forming a waste collection volume. An upper portion of the main body, also called a terminal, emerges above ground, creating an entrance to the waste collection volume located underground. An opening 112 is made in this terminal of the main body.
[0063] A shutter 114 is arranged to cover the opening 112 in the terminal. A fill level detector 120 is installed on a lower side of the main body terminal, emitting detection waves towards the waste collection volume located underground, as illustrated in Figures 2 and 3. An indicator 140 is placed on an exterior surface of the terminal and is visible to users and by collecting organizations.
[0064] A method for warning of the filling level of a waste collection container 100 according to the invention is now described.
[0065] Illustrates the steps of the container fill level warning method 100 comprising the fill level detector 120, the indicator 140 and the control module, without limitation.
[0066] A first step S n 1 consists of measuring the filling level h of the container by the detector 120. Preferably, a signal containing the information of the filling level h is transmitted by the detector 120 to the control module. Upon receipt of this information of the filling level, a second step S n 2, the control module compares the measured filling level h with the preset filling level h p .
[0067] Preferably, when the filling level h is lower than the predefined filling level hp , the indicator displays the default state (step S3a), as mentioned previously. On the other hand, if the filling level h is the same as or higher than the predefined filling level h p , the indicator 140 displays the information about reaching the filling limit, as previously described (step S3b). For example, this can result in a display of a text “Full” if the indicator has a screen, by lighting up the indicator if it is off by default, or by a change in its color from green to red if the indicator is an LED.
[0068] In another exemplary implementation, the container 100 is also equipped with the brightness sensor configured to measure an ambient brightness l a. The control module is in this case configured to modify the display state of the fill level indicator 140 according to the ambient brightness information. We will describe below the case in which the fill level indicator 140 is illuminated, without limitation.
[0069] According to a first variant of this implementation example, as illustrated in the, when the filling level h is lower than the predefined filling level h p , the luminous filling level indicator 140 is inactive (step S3a0), i.e., it goes out. In addition, the warning method comprises a step of measuring the ambient brightness S l 1, performed by the light sensor.
[0070] Preferably, a signal containing the information on the measured ambient brightness is transmitted by the brightness sensor to the control module. Upon receipt of the ambient brightness information, the a , as a brightness comparison step S l 2, the control module compares the ambient brightness l a measured at at least one predefined ambient brightness threshold value. Depending on the result of the comparison, the control module adjusts the display state of the indicator 140 by preferably changing a light intensity of the luminous indicator 140 (step S4).
[0071] Preferably, in a first sub-step S l 2a of the brightness comparison step S l 2, if the measured ambient brightness l ais greater than or equal to a first threshold value l1, predefined for example to preferentially indicate ambient daytime brightness, the indicator 140 displays the information of reaching the filling limit with the light intensity equal to 100% of a predefined light intensity (display sub-step S4a of the display state modification step S4), thus ensuring the visibility of the filling level indicator 140 during the day.
[0072] If the measured ambient brightness a is less than the first predefined threshold value l1, according to a first example (optionally, not shown in the), the indicator 140 displays the information of reaching the filling limit with the reduced light intensity, i.e., less than 100%, for example less than 90% of the predefined light intensity, typically between 30% and 70% of the predefined light intensity.
[0073] If the measured ambient brightness a is less than the first predefined threshold value l1, according to a second example (illustrated in the), a second sub-step S l 2b of the brightness comparison step S l 2 with a second threshold value l2 which is lower than the first threshold value l1 and indicates for example a night ambient brightness is carried out. If the measured ambient brightness l a is less than or equal to the second threshold value l2, the indicator 140 is inactive (display sub-step S4b of the modification step S4), thus saving electrical energy and reducing light pollution.
[0074] According to this second example, if the measured ambient brightness ais less than the first threshold value l1 and greater than the second threshold value l2, indicating for example an ambient brightness corresponding to nightfall or daybreak, the indicator 140 displays the information of reaching the filling limit with the reduced light intensity, i.e., less than 100%, normally less than 90%, typically between 30% and 70%, for example 50%, of the predefined light intensity (display sub-step S4c of the modification step S4). This approach aims to save electrical energy, reduce light pollution while maintaining the visibility of the indicator for users.
[0075] Advantageously, the control module analyzes a variation in ambient brightness over time.
[0076] As a non-limiting example, when the measured ambient brightness ais lower than the first threshold value l1 and higher than the second threshold value l2, an analysis of the variation in ambient brightness is carried out by measuring at regular intervals over time and by comparing it with a set of predefined threshold values. If the ambient brightness l a continues to decrease over time, thus indicating, for example, nightfall, the indicator light may reduce its light intensity over time depending on the ambient brightness or reduce it to, for example, 50% of the preset light intensity, then the indicator light may turn off after a certain time, for example, 3 hours. If, on the other hand, the ambient brightness acontinues to increase over time, for example indicating daybreak, the control module may communicate to the light indicator 140 to illuminate with the light intensity increasing according to the ambient brightness, for example up to 100% of the predefined light intensity.
[0077] According to a second variant of this implementation example, when the filling level h is lower than the predefined filling level h p , the indicator light remains active (e.g. lit) in its default state, but with a display different from the display of the information about reaching the filling limit. In this case, the ambient brightness comparison step S l 2, including steps S l 2a and S l2b, and the display state changing step S4, comprising steps S4a, S4b and S4c, are also applied to change the light intensity of the indicator to its default state according to the ambient brightness, as illustrated in.
