Description

technical field

[0001] The invention relates to containers for waste collection, more particularly lids for waste collection containers made in at least two parts. State of the art

[0002] Prior art has shown a waste collection container comprising a tank and a two-part lid. Such waste collection containers are, for example, fixed waste containers as defined in standard NF EN 12574:2017. A two-part lid typically comprises a first part, a user lid intended to be opened by a user to deposit waste into the receiving tank, and a second part, a collection lid intended to be opened during waste collection. Since these two lid parts are movable relative to each other, there is a gap between them to allow for this movement.

[0003] Waste collection containers are generally located outdoors. Therefore, when it rains, rainwater can enter the waste collection tank through the gap between the user lid and the collection lid. Furthermore, rainwater that doesn't enter the tank can collect on the lid, and when a user opens the lid to deposit waste, this collected rainwater flows by gravity from the top of the lid into the tank through the gap between the user lid and the collection lid. The same problem arises with dew that can form on the top of the lid.In the cases mentioned above, liquid is introduced into the waste collection tank, which is undesirable, particularly to avoid increasing the weight of the container or reducing its waste storage capacity.

[0004] It has been proposed to cover the gap between the two lid sections. However, such a solution is not entirely satisfactory as it is not robust and may hinder the opening of the user lid and / or the collection lid. Summary of the invention

[0005] The invention aims to avoid the aforementioned disadvantages by providing a container for waste collection comprising a two-part lid for which the introduction of liquid into the waste collection tank is limited or prevented via a gap existing between the two parts of the lid.

[0006] To this end, the invention relates to a lid for a waste collection container, the lid being intended to be attached to a waste receiving tank of a waste collection container and being made in at least two parts, a first part of the lid being movable relative to a second part of the lid, at least a gap separating the first part of the lid and the second part of the lid, characterized in that the lid includes a liquid evacuation channel arranged at least in part opposite the gap separating the first part of the lid and the second part of the lid, the liquid evacuation channel being intended, when the lid is attached to a waste receiving tank, to evacuate outside the waste receiving tank liquid flowing through the gap separating the first part of the lid and the second part of the lid.

[0007] Thus, the liquid drainage channel allows the liquid flowing through the gap between the first and second lid sections to be collected and discharged outside the waste collection tank. A lid for a waste collection container according to the invention therefore limits, or even prevents, the introduction of liquid, typically rainwater or dew, through the gap between the first and second lid sections, for example, when the first or second lid section is opened.

[0008] By "intended, when the cover is attached to a waste receiving tank, to discharge outside the waste receiving tank liquid flowing through the gap separating the first part of the cover and the second part of the cover" we mean to designate the fact that the liquid discharge channel, when it receives liquid via the gap separating the first part of the cover and the second part of the cover, is configured to allow at least a part of this liquid to flow, in particular by gravity, outside the tank on which the cover is attached in order to discharge it, for example, onto the roadway.

[0009] The waste collection container lid according to the invention is selected from any type of lid suitable for use with a two-part collection container, for example, a fixed waste container. In a preferred embodiment, the lid is designed for a waste collection container as defined in standard NF EN 12574:2017 or in standard NF EN 840:2020.

[0010] In one embodiment, the first lid section, which is movable relative to the second lid section and to the tank, is a user lid, meaning a lid designed to be operated directly or indirectly by a user to open the container and deposit waste into the waste collection tank. This first lid section is sometimes called an access hatch or access flap. Depending on the embodiment, it can open, for example, by pivoting or sliding.

[0011] Depending on the embodiment, the second lid section may also be movable relative to the first lid section and to the tank. Such a second lid section corresponds, for example, to a collection lid, also called a discharge lid, designed to be opened when the contents of the waste collection tank are emptied. This second lid section is sometimes called a discharge or collection hatch, or a discharge or collection flap.

[0012] The invention may include one or more of the following optional features taken alone or in combination.

[0013] In one embodiment, at least a portion of the liquid drainage channel is formed by a gutter projecting from a longitudinal end of the second part of the cover and positioned opposite the gap separating the first and second parts of the cover. The term "gutter" refers to a structure that advantageously collects liquid flowing through the gap between the first and second parts of the cover, preventing it from flowing into the waste collection tank, and also guiding the collected liquid along a predetermined path.

[0014] In one embodiment, the gutter is inclined with respect to a horizontal reference axis. This inclination advantageously facilitates the gravity flow of the liquid in the gutter, thereby facilitating its evacuation to the rest of the liquid drainage channel and thus facilitating the evacuation of liquid from the waste collection tank. The inclination can vary depending on the embodiment and is, for example, between 1° and 10°, preferably between 1° and 5°. The "horizontal reference axis" is understood to be an axis that is horizontal with respect to a typical operating position of the waste collection container. In particular, it is an axis that is orthogonal to an axis oriented along the direction of gravity. In other embodiments, the gutter may be provided that it is not inclined with respect to the horizontal reference axis.In this case, it is possible, for example, to provide for the liquid to drain from the gutter by overflow and / or via a liquid drainage hole provided in the wall of the gutter.

[0015] Advantageously, the first and second lid sections are arranged so that the gap between them extends over substantially the entire width of the first and / or second lid sections, and the gutter extends along the length of the gap between them. This design reduces the risk of liquid flowing through the two lid sections not being collected by the gutter and instead flowing into the waste collection tank.In other words, a larger part, preferably all, of the liquid flowing through the gap between the first and second parts of the lid is collected in the gutter in order to discharge it outside the waste collection tank.

[0016] Preferably, the liquid discharge channel further includes at least one liquid discharge conduit comprising an upstream end for receiving liquid flowing from the gutter and a downstream end for discharging the liquid outside the waste receiving tank. This is a simple and effective means of conveying the liquid that has flowed into the gutter outside the waste receiving tank. The term "conduit" refers to any structure that guides the flow of liquid along a predetermined path. A conduit is, for example, a channel, tube, pipe, or gutter.

[0017] In one embodiment, the lid for the waste collection container comprises two liquid drainage channels. The upstream end of the first drainage channel is designed to receive liquid flowing from a first longitudinal end of the gutter, and the upstream end of the second drainage channel is designed to receive liquid from a second longitudinal end of the gutter, opposite the first longitudinal end. Thus, liquid is drained from the gutter to the outside of the waste collection container via both longitudinal ends of the gutter. This allows for faster and more efficient drainage of the liquid that is poured into the gutter.This reduces the risk of liquid flowing from the gutter into the waste collection tank because the gutter's liquid drainage capacity is exceeded by a large and rapid influx of liquid.

[0018] In one embodiment, the liquid drainage channel is formed by a pipe, preferably made of plastic. This is a simple and economical means of draining liquid from the gutter to the outside of the waste collection tank. For example, it is easy to adapt the shape and dimensions of the pipe to the shape and dimensions of the lid and / or the shape and dimensions of the tank to facilitate container manufacturing. Furthermore, maintenance of the liquid drainage channel is simplified, particularly by allowing for easy and economical replacement of the pipe when it is damaged, without having to replace other parts of the container.

[0019] In one embodiment, the cover may be provided with at least one maintenance access hatch, opening, for example, from an upper face of the cover, allowing access to the fluid drainage conduit, in particular the pipe, for maintenance purposes. The maintenance hatch allows, for example, easy access to an inlet or outlet of the pipe in order to inject fluid into it to ensure that the pipe is not at least partially blocked. The maintenance hatch may be provided to be movable and / or removable.

[0020] Advantageously, the lid for the waste collection container also includes means for attaching the liquid discharge conduit, in particular the hose, to the lid. By reducing the hose's freedom of movement, the risk of accidental damage or detachment is reduced, thus improving its service life. The means for attaching the hose to the lid include, for example, retaining rings coupled with fixing screws to secure the hose. Alternatively, hooks extending from an inner face of the lid may be provided, each hook configured to hold a section of the hose against the lid. These hooks may, for example, be integral to the lid.

[0021] In one embodiment, the liquid drainage pipe is formed as one piece with the lid. The lid, and therefore the waste collection container, is thus simpler and less expensive to manufacture, particularly due to the reduced number of parts required for assembly. Furthermore, it can be provided that the liquid drainage pipe is formed, at least in part, as one piece with the waste receiving tank onto which the lid is mounted.

[0022] In one embodiment, the gutter includes, at at least one longitudinal end, a liquid drainage opening for the passage of liquid from the gutter to the drain pipe. This is a simple and economical means of transferring liquid from the gutter to the drain pipe. An upstream end of the drain pipe, for example a pipe, may be directly connected to the liquid drainage opening. In a particular embodiment, the gutter includes as many liquid drainage openings as there are drain pipes.

[0023] In one embodiment, the portion of the liquid drainage channel arranged opposite the opening forms at least one ramp comprising a high point and at least one low point for the drainage of liquid in a direction from the high point to the low point. It is understood that the presence of this high point and this low point advantageously facilitates gravity drainage of the liquid present in the gutter, in particular to facilitate its evacuation to the rest of the liquid drainage channel and thus to facilitate the evacuation of liquid from the waste receiving tank. The ramp may be provided with at least two points located on either side of the high point so that the liquid flows in two directions, particularly when two liquid drainage channels are present. The ramp may then, for example, have a roof-like shape.

[0024] Advantageously, the ramp is straight and inclined or not with respect to a horizontal reference axis. This inclination advantageously facilitates gravity flow of the liquid present in this section of the liquid discharge channel, thereby facilitating its evacuation to the rest of the liquid discharge channel and thus facilitating the evacuation of liquid from the waste receiving tank. The inclination can vary depending on the embodiment and is, for example, between 1° and 10°, preferably between 1° and 5°. Alternatively, the ramp can be designed to have at least a partially curved shape.

[0025] The invention also relates to a waste collection container comprising a waste receiving tank and a lid attached to the tank, the lid being a lid as described above. Brief description of the figures

THE [ Fig. 7 ] is a perspective view of the underside of part of the second lid section of the waste container. figure 1 . Detailed description

[0027] Figures 1 to 7 depict a container 1 for waste collection according to an embodiment of the invention. The container 1 shown in the figures is a fixed waste container with a capacity ranging from 1,500 L to 10,000 L, preferably between 1,800 L and 3,200 L, typically 1,900 L, or even 2,900 L. More specifically, the container 1 according to this embodiment is of the type described in standard NF EN 12574:2017. Alternatively, the container could, for example, be of the type described in standard NF EN 840:2020. According to other embodiments, the container 1 could be of a different type.

[0028] According to this embodiment, the container 1 includes a waste receiving tank 2, a lid 3 including a liquid evacuation channel 10.

[0029] Waste receiving tank 2 is designed to receive and store waste deposited there by a user. In this case, it comprises four side walls and one bottom wall.

[0030] The lid 3 is attached to the waste collection tank 2. According to this embodiment, the lid 3 is made of four parts. More specifically, a first part 4 of the lid 3 is movable relative to a second part 5 of the lid 3 and relative to the tank 2. More specifically, the first part 4 of the lid 3 here forms a user lid intended to be handled directly or indirectly by a user who wishes to deposit waste onto it. The first part 4 of the lid 3 is therefore movable by pivoting between a closed position and an open position. The second part 5 of the lid 3 is, in this case, also movable relative to the first part 4 of the lid 3 and relative to the tank 2.More specifically, the second part 5 of lid 3 forms a collection lid that pivots between a closed and an open position, allowing the contents of the tank 2 to be collected, for example, into a waste collection bin. The first part 4 of lid 3 opens onto a front edge of container 1, while the second part 5 of lid 3 opens onto a rear edge of container 1, located opposite the front edge. Thus, the respective pivot axes of the first and second parts 4 and 5 of lid 3 are arranged at a mid-portion of container 1. figure 2 illustrates container 1 when the first and second parts 4, 5 of lid 3 are in their open positions.

[0031] As illustrated in the figure 1The lid 3 further comprises a third part 7 of lid 3 and a fourth part 8 of lid which are fixedly mounted relative to the tank 2 and to the first part 4 and second part 5 of lid 3. The second part 5 of lid 3 extends from one lateral edge to the other of the container 1 while the first part 4 of lid extends between the third and fourth parts 7, 8 of lid 3. According to the embodiments, it may be provided that one and / or the other of these third part 7 and fourth part 8 of lid 3 are not present.

[0032] A set of 6 separates the first part 4 of lid 3 and the second part 5 of lid 3 ( figures 3 and 4This gap 6 allows the first and second parts 4, 5 of the cover 3 to pivot relative to each other between their respective open and closed positions. In this case, the gap 6 forms a longitudinal slot, and the first part 4 of the cover 3 and the second part 5 of the cover 3 are arranged so that the gap 6 extends over approximately the entire width of the first part 4 of the cover 3. In other words, the length of the gap 6 corresponds approximately to the width of the first part 4 of the cover 3.

[0033] The liquid drainage channel 10 is arranged at least in part opposite the gap 6 separating the first part 4 of cover 3 and the second part 5 of cover 3. The liquid drainage channel 10 is configured to discharge outside the waste receiving tank 2 of the liquid flowing through the gap 6. According to the present embodiment, the liquid drainage channel 10 comprises at least one gutter 11 and two liquid drainage conduits, each of which is formed by a pipe 12.

[0034] According to the present embodiment, as illustrated in figures 3 to 6, the gutter 11 is formed from the material of the second part 5 of cover 3 and extends projecting from the longitudinal end of the second part 5 of cover 3 which is opposite the first part 4 of cover 3. More particularly, the gutter 11 is arranged opposite the gap 6 separating the first and second parts 4, 5 of cover 3, along the entire length of the gap 6 ( figures 3 and 4 ). Thus positioned, the gutter 11 is suitable for collecting liquid flowing through the gap 6, for example in case of rain or when the first part 4 of the cover 3 is opened by a user while liquid is present on its upper surface. In the present case, the gutter 11 includes two liquid drainage openings 13 for the passage of liquid from the gutter 11 to the pipe 12 ( figure 6The two liquid drainage ports 13 are arranged respectively at one of the longitudinal ends of the gutter 11. Thus, when liquid present in the gutter 11 reaches the level of one of the liquid drainage ports 13, it is discharged by gravity through the liquid drainage port 13. In some embodiments, only one liquid drainage port 13 may be present. In an alternative embodiment, the gutter 11 may be inclined with respect to a horizontal reference axis to facilitate the gravity drainage of liquid through the liquid drainage port 13.

[0035] Each liquid drainage conduit is formed by a pipe 12 which, in this case, is made of plastic. Each pipe 12 comprises an upstream end 14 for receiving liquid flowing from the gutter 11 via the liquid drainage port 13 and a downstream end 15 for discharging the liquid outside the waste receiving tank 2. More specifically, as illustrated in figures 6 And 7 The respective upstream ends 14 of each pipe 12 are directly fixed respectively to one of the liquid discharge ports 13. On the figures 6 And 7 Only a portion of the pipes 12 is shown. The downstream end 15 of the pipe can thus be extended, for example by continuing its course along an external face of a side wall of the waste receiving tank 2.

[0036] The cover 3 also includes means 16 for attaching the pipe 12 to the cover 3. In this case, the means 16 for attaching the pipe 12 to the cover comprise, for each pipe 12, two retaining rings 17 for the pipe 12 coupled with fixing screws 18. The means 16 for attaching the pipe 12 to the cover thus hold the pipe 12 in place, in contact with an inner face of the cover 3. This prevents the pipe from hanging down, which would increase the risk of accidental damage. Of course, depending on the embodiment, the pipe can be attached to the cover differently. For example, protrusions can be provided that extend outward from the inner face of the cover 3 and form retaining hooks for the pipe 12.

[0037] According to one embodiment, it can be provided that the liquid evacuation conduit comes from the material with the cover 3 and / or the waste receiving tank 2.

[0038] The following are described the different stages of a liquid evacuation for a container 1 as described above.

[0039] According to a first example, when container 1 is placed outdoors during rainy weather, rain flows directly through the gap 6 separating the first part 4 of the lid 3 and the second part 5 of the lid. Instead of falling into the waste collection tank 2, as would be the case with a prior art container, the rainwater flows into the gutter 11 via the gap 6. The accumulation of rainwater in the gutter 11 raises the liquid level in the gutter 11 until it reaches a level flush with the liquid discharge openings 13. From this point, the additional rainwater that continues to flow through the gap 6 causes the accumulated water in the gutter 11 to overflow into the liquid discharge openings 13.Once past the liquid discharge opening 13, the rainwater flows by gravity along the pipe 12 forming the liquid discharge conduit, from the upstream end 14 of this pipe 12 to its downstream end 15 from which the water is discharged out of the pipe 12, outside the waste receiving tank 2.

[0040] According to a second example, liquid, such as rainwater or dew, is likely to accumulate on an external face of the cover 3, in particular on an external face of the first part 4 of the cover 3. When a user wishes to deposit waste into the tank 2, they open the first part 4 of the cover 3. This opening causes the water accumulated on the external face of the first part 4 of the cover 3 to flow through the gap 6 separating the first and second parts 4, 5 of the cover 3. Instead of falling into the waste receiving tank 2, as would be the case with a prior art container, the accumulated water flows into the gutter 11. The accumulation of water in the gutter 11 causes the liquid level in the gutter 11 to rise until it reaches a level flush with the liquid discharge openings 13.From this point on, the additional water that continues to flow through the set 6 causes the accumulated water in the gutter 11 to overflow into the liquid discharge ports 13. Once past the liquid discharge port 13, the water flows by gravity along the pipe 12 forming the liquid discharge conduit, from the upstream end 14 of this pipe 12 to its downstream end 15, from which the water is discharged out of the pipe 12, outside the waste receiving tank 2.

[0041] The invention is not limited to the embodiments presented, and other embodiments will be obvious to those skilled in the art. In particular, the gutter 11, which in the embodiment presented above is straight, may be inclined or not with respect to a horizontal reference axis. An inclined gutter facilitates the drainage of liquid towards a liquid drainage opening 13. In this case, it is understood that the gutter 11 comprises only one liquid drainage opening 13. Alternatively, the gutter 11 may be roof-shaped and thus have a central high point and two low points located respectively at the longitudinal ends of the gutter 11, so as to facilitate the drainage of liquid by gravity through two liquid drainage openings 13 located respectively at the two longitudinal ends of the gutter 11.

[0042] In another embodiment, the upper face of the first part 4 of the cover 3 may be provided with guide reliefs, for example guide grooves, arranged to guide the flow of liquid present on this upper face towards the gap 6 and thus into the gutter. Such grooves make it possible, in particular, to distribute the liquid flow as homogeneously as possible along the entire length of the gutter 11 in order to reduce the risk of overflow due to a rapid and localized flow of a large quantity of liquid into the gutter 11.
