Description

L'invention concerne les bacs pour la collecte de déchets et plus particulièrement les émissions sonores dues au dépôt de déchets dans de tels bacs.The invention relates to bins for the collection of waste and more particularly the sound emissions due to the deposit of waste in such bins.

Pour trier les déchets lors de la collecte, il est connu de disposer plusieurs bacs, côte à côte. Chaque bac est destiné à recevoir un type particulier de déchets, par exemple un bac est destiné à recevoir des déchets comprenant majoritairement du plastique et un autre bac est destiné à recevoir des déchets comprenant majoritairement du verre.To sort the waste during collection, it is known to have several bins, side by side. Each bin is intended to receive a particular type of waste, for example a bin is intended to receive waste mainly comprising plastic and another bin is intended to receive waste mainly comprising glass.

Dans le cas des déchets comprenant du verre, notamment les bouteilles vides, l'utilisation du bac dédié peut être relativement bruyante. En effet, lorsque le bac est vide, une bouteille en verre, en chutant dans le bac, peut se briser en percutant les parois du bac. Même lorsque le bac est partiellement rempli de tessons de verre, un déchet en verre qui chute dans le bac se brise sur les tessons et génère du bruit. De même, même sans se briser, la bouteille qui chute dans le bac et percute d'autres bouteilles génère du bruit.In the case of waste including glass, including empty bottles, the use of the dedicated tray can be relatively noisy. Indeed, when the tray is empty, a glass bottle, falling in the tray, can break by striking the walls of the tray. Even when the tank is partially filled with shards of glass, a glass waste that falls into the tank breaks on the shards and generates noise. Similarly, even without breaking, the bottle that falls into the tank and collides with other bottles generates noise.

Le bruit produit lors du dépôt de déchets comprenant du verre dans des bacs dédiés est susceptible de gêner les personnes à proximité des bacs. Notamment, dans les environnements urbains, des bacs pour la collecte de déchets en verre peuvent être positionnés à proximité de fenêtres d'habitations.The noise produced during the deposition of waste including glass in dedicated bins is likely to annoy people near the bins. Especially in urban environments, bins for the collection of glass waste can be positioned near windows of houses.

Pour limiter le bruit généré par le bac, il est connu d'utiliser des bacs avec des parois plus épaisses afin d'absorber le bruit émis à l'intérieur du bac. Toutefois, le bruit est faiblement atténué et le coût de fabrication du bac est augmenté.To limit the noise generated by the tray, it is known to use trays with thicker walls to absorb the noise emitted inside the tray. However, the noise is slightly attenuated and the cost of manufacturing the tray is increased.

Un but de l'invention est donc de fournir un bac pour la collecte de déchets plus silencieux.An object of the invention is therefore to provide a bin for the collection of quieter waste.

Pour ce faire, on prévoit, selon l'invention, un bac pour la collecte de déchets, caractérisé en ce qu'il comprend une cuve dont au moins une paroi est recouverte, sur une face interne, par une feuille souple qui comprend un matériau alvéolaire et/ou un élastomère comprenant un groupe butyle, le matériau alvéolaire (24, 124) et le matériau élastomère ont la propriété d'être absorbant et/ou isolant acoustique.To do this, according to the invention, there is provided a bin for the collection of waste, characterized in that it comprises a vessel of which at least one wall is covered on an inner face by a flexible sheet which comprises a material alveolar and / or an elastomer comprising a butyl group, the cellular material (24, 124) and the elastomeric material have the property of being absorbent and / or acoustic insulator.

Ainsi, le bruit généré par la chute et/ou le bris du déchet dans la cuve est soit absorbé par le matériau alvéolaire, soit reste confiné dans la cuve si le matériau alvéolaire est un isolant acoustique. De même, l'élastomère comprenant le groupe butyle peut absorber les ondes sonores émises lors de la chute du déchet ou alors se comporter comme un isolant acoustique. Dans tous les cas, des personnes se trouvant à proximité du bac sont moins gênés par le bruit de la collecte du déchet dans le bac.Thus, the noise generated by the fall and / or breakage of the waste in the tank is either absorbed by the cellular material or remains confined in the tank if the cellular material is an acoustic insulator. Similarly, the elastomer comprising the butyl group can absorb the sound waves emitted during the fall of the waste or behave like an acoustic insulator. In all cases, people in the vicinity of the tank are less disturbed by the noise of the collection of waste in the tray.

On notera ainsi que grâce au bac selon l'invention, on encourage le tri sélectif du verre, notamment dans des environnements urbains. En effet, en raison du bruit habituellement générés par le dépôt de déchets en verre dans des bacs dédiés, de nombreux immeubles d'habitations n'installent pas de tels bacs. Or, le verre est un matériau qui se recycle facilement. En installant le bac selon l'invention dans des immeubles d'habitations, on encourage les habitants à procéder au tri sélectif des déchets en verre car le bruit généré par le tri sélectif n'est plus gênant pour les habitants.It will thus be noted that thanks to the container according to the invention, selective sorting of the glass is encouraged, particularly in urban environments. Indeed, due to the noise usually generated by the deposit of glass waste in dedicated bins, many apartment buildings do not install such bins. Now, glass is a material that recycles easily. By installing the tank according to the invention in apartment buildings, the inhabitants are encouraged to proceed with the selective sorting of glass waste because the noise generated by selective sorting is no longer inconvenient for the inhabitants.

De préférence, la feuille appartient à une enveloppe qui recouvre toutes les faces internes de la cuve.Preferably, the sheet belongs to an envelope which covers all the internal faces of the tank.

De cette façon on accroit la capacité du bac à confiner le bruit émis à l'intérieur de celui-ci.In this way we increase the capacity of the tank to contain the noise emitted inside thereof.

Avantageusement, le matériau alvéolaire comprend une mousse solide.Advantageously, the cellular material comprises a solid foam.

Les inventeurs ont constaté que la mousse solide produit de bons résultats en termes d'absorption et/ou d'isolation acoustique, tout en étant légère et en occupant un volume faible dans le bac.The inventors have found that the solid foam produces good results in terms of absorption and / or acoustic insulation, while being light and occupying a small volume in the tray.

Selon un mode de réalisation, la mousse solide comprend du polyéthylène basse densité, de préférence à cellules fermées ou semi-fermées.According to one embodiment, the solid foam comprises low density polyethylene, preferably with closed or semi-closed cells.

La mousse solide en polyéthylène basse densité est simple à produire et présente des capacités de résistance aux contraintes mécaniques, qui peuvent être imposées par les déchets, satisfaisantes. De plus, lorsque le polyéthylène basse densité est à cellules fermées ou semi-fermées, il ne se dégrade pas sous l'action d'un liquide, par exemple de l'eau de pluie, ou du lixiviat. La mousse solide est donc lavable.The solid foam of low density polyethylene is simple to produce and has resilience capabilities to mechanical stresses, which can be imposed by waste, satisfactory. In addition, when the low density polyethylene is closed cell or semi-closed, it does not degrade under the action of a liquid, for example rainwater, or leachate. The solid foam is washable.

De préférence, la feuille comprend une toile comprenant du polypropylène et/ou du polyester enduit d'une pellicule de polychlorure de vinyle.Preferably, the sheet comprises a fabric comprising polypropylene and / or polyester coated with a polyvinyl chloride film.

La feuille est donc plus résistante aux contraintes mécaniques imposées par les déchets. La feuille présente notamment moins de risques de déchirure en étant plus résistante au cisaillement. De plus, la toile peut être lavée car elle n'est également pas dégradée par l'action de l'eau.The sheet is therefore more resistant to the mechanical stresses imposed by the waste. The sheet has in particular less risk of tearing by being more resistant to shearing. In addition, the canvas can be washed because it is also not degraded by the action of water.

Avantageusement, la feuille entoure totalement le matériau alvéolaire.Advantageously, the sheet completely surrounds the cellular material.

Ainsi, la feuille protège le matériau alvéolaire. En outre, la feuille contraint la forme du matériau alvéolaire. La feuille agit alors comme une gaine protectrice pour le matériau alvéolaire. On peut donc aisément remplacer la feuille et par conséquent le matériau alvéolaire par simple décrochage de la feuille. La maintenance du bac est donc plus simple.Thus, the sheet protects the cellular material. In addition, the sheet constrains the shape of the cellular material. The sheet then acts as a protective sheath for the cellular material. It is therefore easy to replace the sheet and therefore the cellular material by simply stalling the sheet. The maintenance of the bin is therefore simpler.

Selon un mode de réalisation, la feuille fixée au matériau alvéolaire au moyen d'au moins une couture et/ou d'une colle.According to one embodiment, the sheet attached to the cellular material by means of at least one seam and / or glue.

De préférence, une extrémité de la feuille est pliée de manière à enserrer une extrémité du matériau alvéolaire afin de fixer la feuille au matériau alvéolaire.Preferably, one end of the sheet is folded so as to grip one end of the cellular material to secure the sheet to the cellular material.

Il s'agit de moyens simples et efficaces pour relier la feuille au matériau alvéolaire.These are simple and effective ways to connect the sheet to the cellular material.

Avantageusement, la feuille est fixée à la cuve au moyen d'au moins un rivet et/ou d'une vis.Advantageously, the sheet is fixed to the tank by means of at least one rivet and / or a screw.

Ainsi, on peut remplacer la feuille facilement en cas de détérioration.Thus, it is possible to replace the sheet easily in case of deterioration.

De préférence, une extrémité de la feuille est fixée à la cuve.Preferably, one end of the sheet is attached to the tank.

Selon un mode de réalisation, l'extrémité de la feuille est fixée à une collerette de la cuve.According to one embodiment, the end of the sheet is attached to a flange of the tank.

On peut donc aisément remplacer la feuille et par conséquent le matériau alvéolaire par simple décrochage de la feuille. La maintenance du bac est donc plus simple.It is therefore easy to replace the sheet and therefore the cellular material by simply stalling the sheet. The maintenance of the bin is therefore simpler.

Il est donc possible de remplacer facilement la feuille si celle-ci est par exemple déchirée par un déchet en verre.It is therefore possible to easily replace the sheet if it is for example torn by a waste glass.

Avantageusement, le bac comporte un couvercle dont une surface interne comporte la feuille comprenant le matériau alvéolaire.Advantageously, the tray has a lid whose inner surface comprises the sheet comprising the cellular material.

La capacité du bac à émettre peu de bruit lorsqu'un utilisateur y dépose des déchets est donc accrue.The capacity of the tank to emit little noise when a user deposits waste there is increased.

On va maintenant décrire, à titre d'exemple non limitatif, deux modes de réalisation de l'invention, à l'aide des figures suivantes :

  • la figure 1 est une vue en perspective d'un bac selon un premier mode de réalisation de l'invention,
  • la figure 2 est une vue en perspective et en transparence de ce bac,
  • la figure 3 est une vue de dessus d'un bac, selon un second mode de réalisation de l'invention, dans lequel on n'a pas représenté un couvercle et une feuille, et
  • la figure 4 est une vue de dessus de ce bac, dans lequel seul le couvercle n'est pas représenté.
Two embodiments of the invention will now be described, by way of nonlimiting example, with the aid of the following figures:
  • the figure 1 is a perspective view of a tray according to a first embodiment of the invention,
  • the figure 2 is a perspective and transparency view of this tray,
  • the figure 3 is a top view of a tray, according to a second embodiment of the invention, in which a lid and a sheet have not been shown, and
  • the figure 4 is a top view of this tray, in which only the cover is not shown.

On a représenté à la figure 1, un bac 10 pour la collecte de déchets, selon un premier mode de réalisation de l'invention.We have shown figure 1 , a tank 10 for the collection of waste, according to a first embodiment of the invention.

Le bac 10 comprend une cuve 12 essentiellement constituée d'une matière plastique, à savoir du polyéthylène, de préférence partiellement ou intégralement recyclé, mais peut, selon une variante du présent mode de réalisation, comprendre un autre matériau plastique ou du métal. La cuve 12 est issue d'un procédé de moulage par injection et est monobloc.The tray 10 comprises a tank 12 consisting essentially of a plastic material, namely polyethylene, preferably partially or completely recycled, but may, according to a variant of the present embodiment, comprise another plastic material or metal. The tank 12 is derived from an injection molding process and is in one piece.

Le bac 10 est ici destiné à recevoir des déchets comprenant essentiellement du verre. Toutefois, il ne s'agit nullement d'une caractéristique limitative, et selon des variantes de ce mode de réalisation, le bac 10 est destiné à recevoir des déchets en plastique ou encore tous types de déchets.The tank 10 is here intended to receive waste essentially comprising glass. However, it is not a limiting feature, and according to variants of this embodiment, the tray 10 is intended to receive plastic waste or all types of waste.

En outre, le bac 10 comprend un couvercle 14, constituée du même matériau que la cuve 12, et comprend un orifice d'introduction 16.In addition, the tray 10 comprises a lid 14, made of the same material as the bowl 12, and comprises an insertion orifice 16.

On a représenté à la figure 2, le bac 10 en perspective et en transparence de façon à laisser apparaître l'intérieur du bac 10.We have shown figure 2 , the tray 10 in perspective and in transparency so as to reveal the interior of the tray 10.

La cuve 12 comprend une poignée 15 qui permet la préhension du bac 10 et son déplacement par un opérateur.The tank 12 comprises a handle 15 which allows the gripping of the tank 10 and its moving by an operator.

De plus, la cuve 12 comprend, sur une partie supérieure selon la direction verticale, une collerette 18. En outre, la cuve 12 est portée par deux roues 20, bien qu'une seule roue 20 soit représentée sur la figure 2. Le bac représenté ici n'a que deux roues mais des bacs à quatre roues sont également concernés par l'invention, de même que des bacs sans roues.In addition, the tank 12 comprises, on an upper portion in the vertical direction, a flange 18. In addition, the tank 12 is carried by two wheels 20, although a single wheel 20 is shown on the figure 2 . The tank shown here has only two wheels but bins with four wheels are also concerned by the invention, as well as bins without wheels.

Les parois de la cuve 12 sont recouvertes, sur leurs faces internes, par une feuille souple 22. Comme toutes les faces internes des parois de la cuve 12 sont recouvertes par la feuille souple 22, cette dernière forme une enveloppe pour les parois de la cuve 12. Selon une variante du présent mode de réalisation, la feuille souple 22 recouvre simplement une ou plusieurs faces internes des parois de la cuve 12, sans recouvrir, au moins partiellement, d'autres faces internes de parois de la cuve 12.The walls of the tank 12 are covered on their internal faces by a flexible sheet 22. As all the internal faces of the walls of the tank 12 are covered by the flexible sheet 22, the latter forms an envelope for the walls of the tank 12. According to a variant of the present embodiment, the flexible sheet 22 simply covers one or more internal faces of the walls of the tank 12, without covering, at least partially, other internal faces of the walls of the tank 12.

Cette feuille souple 22 peut être tissée ou thermoformée et comprend alors par exemple une matière plastique telle que le polyester. Dans le présent mode de réalisation, il s'agit d'une toile qui comprend du polypropylène. Selon une variante, la toile comprend du polyester enduit d'une pellicule de chlorure de vinyle, également désigné par l'acronyme PVC. Selon une autre variante, la toile comprend un mélange des deux compositions suscitées. Le polyester enduit de chlorure de vinyle a notamment pour propriété de se déchirer difficilement. L'utilisation de ce matériau est donc indiquée dans le cas de bacs pour la collecte de déchets comprenant principalement du verre. La feuille souple 22 présente ainsi une probabilité faible de se déchirer sous l'effet du frottement des tessons de verre contre la feuille souple 22, elle est donc résistante au cisaillement. Par contre, la feuille souple 22 peut être percée, ce qui permet de fixer facilement la feuille souple 22 à la cuve 12 par des moyens que l'on va décrire plus loin.This flexible sheet 22 may be woven or thermoformed and then comprises for example a plastic material such as polyester. In the present embodiment, it is a fabric that comprises polypropylene. According to one variant, the fabric comprises polyester coated with a film of vinyl chloride, also designated by the acronym PVC. According to another variant, the fabric comprises a mixture of the two compositions raised. The vinyl chloride-coated polyester has the particular property of tearing with difficulty. The use of this material is therefore indicated in the case of bins for waste collection mainly comprising glass. The flexible sheet 22 thus has a low probability of tearing under the effect of the friction of the shards of glass against the flexible sheet 22, it is therefore resistant to shear. On the other hand, the flexible sheet 22 can be pierced, which makes it easy to fix the flexible sheet 22 to the tank 12 by means that will be described later.

La feuille souple 22 forme un réservoir et comprend, à l'intérieur de ce réservoir, un matériau alvéolaire 24 qui a la propriété d'être un matériau absorbant acoustique. La feuille souple 22 entoure donc totalement le matériau alvéolaire 24.The flexible sheet 22 forms a reservoir and comprises, inside this reservoir, a cellular material 24 which has the property of being an acoustic absorbing material. The flexible sheet 22 thus completely surrounds the cellular material 24.

Ici, le matériau alvéolaire 24 se présente sous la forme d'une mousse solide qui comprend essentiellement un polymère. Dans ce mode de réalisation, le polymère est constitué de polyéthylène basse densité, également désigné par l'acronyme PEBD. Le polyéthylène est ici à cellules fermées, mais peut, selon une variante, être à cellules semi-fermées de façon, dans les deux cas, à être étanche. On limite ainsi les infiltrations de lixiviat dans le matériau alvéolaire 24.Here, the cellular material 24 is in the form of a solid foam which essentially comprises a polymer. In this embodiment, the polymer is made of low density polyethylene, also referred to as LDPE. The polyethylene is here closed cell, but may alternatively be semi-closed cells so in both cases to be sealed. This limits the infiltration of leachate into the cellular material 24.

Selon une variante du présent mode de réalisation, le matériau alvéolaire 24 est remplacé par un matériau élastomère qui comprend un groupe butyle. Le matériau élastomère est un isolant acoustique. De façon avantageuse, on peut également associer les compositions suscitées. On utilise alors le matériau alvéolaire 24 en tant qu'absorbant acoustique et le matériau élastomère en tant que isolant acoustique.According to a variant of the present embodiment, the cellular material 24 is replaced by an elastomeric material which comprises a butyl group. The elastomeric material is an acoustic insulator. Advantageously, the abovementioned compositions can also be associated. The cellular material 24 is then used as an absorbent acoustical and elastomeric material as acoustic insulation.

Le matériau alvéolaire 24 est un absorbant acoustique. Cela signifie que lorsque le couvercle 14 est dans une position fermée, visible aux figures 1 et 2, c'est-à-dire rabattu sur la cuve 12, le bruit produit dans le bac 10 est fortement atténué de sorte qu'un utilisateur à proximité du bac 10, perçoive faiblement les sons émis depuis l'intérieur du bac 10. Les inventeurs ont notamment constaté que le bruit s'échappant de l'intérieur d'un bac 10 tel que décrit, lorsqu'une bouteille en verre y est introduire, est atténué d'au moins 10 décibels, voire plus, par rapport à un bac qui ne comporte pas la feuille souple 22 et le matériau alvéolaire 24.The cellular material 24 is an acoustic absorbent. This means that when the lid 14 is in a closed position, visible to Figures 1 and 2 , that is to say, folded on the tank 12, the noise produced in the tray 10 is greatly reduced so that a user near the tray 10, weakly perceive the sounds emitted from the inside of the tray 10. The inventors have found that the noise escaping from the inside of a tank 10 as described, when a glass bottle is introduced therein, is attenuated by at least 10 decibels or more, compared to a tank which does not comprise the flexible sheet 22 and the cellular material 24.

La feuille souple 22 est ici cousue au matériau alvéolaire 24. Selon une variante, la feuille souple 22 est collée au matériau alvéolaire 24. Pour renforcer la longévité de la liaison entre la feuille souple 22 et le matériau alvéolaire 24, on peut également associer la colle et la couture.The flexible sheet 22 is here sewn with the cellular material 24. According to one variant, the flexible sheet 22 is bonded to the cellular material 24. In order to reinforce the longevity of the connection between the flexible sheet 22 and the cellular material 24, it is also possible to associate the glue and sewing.

La feuille souple 22 est fixée aux faces internes des parois de la cuve 12, par son extrémité supérieure, selon la direction verticale, à proximité mais en dessous de la collerette 18. Cette fixation peut se faire au moyen de rivets ou de vis, ou encore d'une association de ces deux moyens. Optionnellement, la fixation de la feuille souple 22 aux faces internes des parois de la cuve 12 s'effectue au moyen d'au moins une baguette rigide, qui comprend essentiellement du métal ou du plastique. La baguette rigide permet de plaquer la feuille souple 22 contre les faces internes des parois de la cuve 12, à l'aide de vis ou de rivets, et d'éviter ainsi que des déchets s'insèrent entre la feuille souple 22 et les parois de la cuve 12. De cette façon, on diminue le risque de blessures pour l'opérateur qui procède au vidage du bac 10 et la liaison entre la feuille souple 22 et les faces internes des parois de la cuve 12 est renforcée.The flexible sheet 22 is fixed to the inner faces of the walls of the tank 12, at its upper end, in the vertical direction, close to but below the collar 18. This attachment can be done by means of rivets or screws, or still an association of these two means. Optionally, the attachment of the flexible sheet 22 to the inner faces of the walls of the tank 12 is effected by means of at least one rigid rod, which essentially comprises metal or plastic. The rigid rod makes it possible to press the flexible sheet 22 against the internal faces of the walls of the tank 12, using screws or rivets, and thus to avoid that waste is inserted between the flexible sheet 22 and the walls. of the tank 12. In this way, the risk of injury to the operator who empties the tank 10 is reduced and the connection between the flexible sheet 22 and the inner faces of the walls of the tank 12 is reinforced.

Comme la feuille souple 22 est fixée à la cuve par une extrémité supérieure, le remplacement de la feuille souple 22, qui comporte le matériau alvéolaire 24, est simple. Cette caractéristique se vérifie d'autant mieux lorsque la feuille souple 22 est fixée au moyen d'au moins un ensemble vis/écrou.As the flexible sheet 22 is attached to the tank by an upper end, the replacement of the flexible sheet 22, which comprises the cellular material 24, is simple. This characteristic is all the better when the flexible sheet 22 is fixed by means of at least one screw / nut assembly.

On va maintenant décrire, à l'aide des figures 3 et 4, un second mode de réalisation de l'invention. Seules les différences avec le premier mode de réalisation vont être explicitées.We will now describe, using Figures 3 and 4 , a second embodiment of the invention. Only the differences with the first embodiment will be explained.

On a représenté à la figure 3 un bac 100 selon un second mode de réalisation de l'invention, qui comprend une cuve 112 munie d'une collerette 118. Dans cette illustration, le couvercle n'est pas représenté, tout comme la feuille souple 122 (qui est en revanche représenté à la figure 4).We have shown figure 3 a tray 100 according to a second embodiment of the invention, which comprises a tank 112 provided with a flange 118. In this illustration, the cover is not shown, as is the flexible sheet 122 (which is represented on the other hand to the figure 4 ).

Comme on le voit sur la figure 3, et par superposition avec la figure 4, le matériau alvéolaire 124 est formé d'un seul tenant et comprend deux parties 124A et 124B. La partie 124A recouvre les faces internes des parois latérales de la cuve 112. En outre, la partie 124B recouvre une face interne du fond de la cuve 112. La partie 124A recouvre entièrement les faces internes des parois latérales de la cuve 112 à l'exception de la partie de paroi de cuve 112 qui comprend un organe de verrouillage 119, complémentaire d'un organe de verrouillage du couvercle du bac 100.As we see on the figure 3 , and by superposition with the figure 4 the cellular material 124 is integrally formed and comprises two portions 124A and 124B. The part 124A covers the inner faces of the side walls of the tank 112. In addition, the portion 124B covers an inner face of the bottom of the tank 112. The portion 124A completely covers the inner faces of the side walls of the tank 112 except of the tank wall portion 112 which comprises a locking member 119, complementary to a locking member of the lid of the tank 100.

Pour protéger le matériau alvéolaire 124 des déchets introduits dans le bac 100, celui-ci est recouvert par une feuille souple 122, visible à la figure 4. Ici, une extrémité supérieure, selon la direction verticale, de la feuille souple 122 ne comprend pas de matériau alvéolaire 124 et est plaquée contre les faces internes des parois de la cuve 112.To protect the cellular material 124 waste introduced into the tray 100, it is covered by a flexible sheet 122, visible at the figure 4 . Here, an upper end, in the vertical direction, of the flexible sheet 122 does not include cellular material 124 and is pressed against the inner faces of the walls of the tank 112.

Selon une variante, la feuille souple 122 est repliée, en son extrémité supérieure selon la direction verticale, de manière à enserrer une extrémité supérieure, selon cette même direction verticale, du matériau alvéolaire 124. Ainsi, l'eau ou le lixiviat ne peuvent s'infiltrer dans le matériau alvéolaire 124.According to one variant, the flexible sheet 122 is folded, at its upper end in the vertical direction, so as to grip an upper end, along the same vertical direction, of the cellular material 124. Thus, water or leachate can not be used. infiltrate into the cellular material 124.

La feuille souple 22 et le matériau alvéolaire 124 sont fixés à la cuve 112 au moyen de plusieurs rivets 126. Huit rivets, sans que ce nombre ne soit une caractéristique limitative vis-à-vis de l'invention, sont disposés sur l'extrémité supérieure, selon la direction verticale, de la feuille souple 122 et parcourent le contour horizontal de cette extrémité supérieure. L'extrémité supérieure de la feuille 122 est fixée à une face interne de la collerette 118 de la cuve 112.The flexible sheet 22 and the cellular material 124 are fixed to the tank 112 by means of several rivets 126. Eight rivets, without this number being a limiting feature with respect to the invention, are arranged on the end greater, in the vertical direction, of the flexible sheet 122 and travel the horizontal contour of this upper end. The upper end of the sheet 122 is attached to an inner face of the flange 118 of the tank 112.

Bien entendu, on peut apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.Of course, the invention can be made many modifications without departing from the scope thereof.

On pourra utiliser des matériaux alvéolaires qui ont la propriété d'être isolant acoustique et des matériaux élastomères qui ont la propriété d'être absorbant acoustique.It will be possible to use cellular materials that have the property of being acoustic insulation and elastomeric materials that have the property of being acoustically absorbent.

On pourra utiliser tous types de matériau alvéolaire 124 et notamment associer ces matériaux entre eux.It will be possible to use all types of cellular material 124 and in particular to associate these materials with each other.

On pourra notamment associer des matériaux qui ont la propriété d'être isolant et/ou absorbant acoustique à des fréquences particulières de façon à couvrir l'ensemble du spectre des fréquences audibles.In particular, it will be possible to combine materials that have the property of being insulating and / or acoustically absorbing at particular frequencies so as to cover the entire spectrum of audible frequencies.

On pourra également fixer la feuille souple 122 ou le matériau alvéolaire 124 par tous moyens à la cuve 112.It is also possible to fix the flexible sheet 122 or the cellular material 124 by any means to the tank 112.

Optionnellement, le couvercle 14 peut comporter, sur une surface interne, la feuille souple 22, qui comprend elle-même le matériau alvéolaire 24.Optionally, the cover 14 may comprise, on an inner surface, the flexible sheet 22, which itself comprises the cellular material 24.

De façon avantageuse, on peut associer un dispositif, de type compensateur ou roue à poudrette, qui réduit le bruit provoqué par le déplacement du bac sur ses roues.Advantageously, one can associate a device, compensator type or crush wheel, which reduces the noise caused by the movement of the tray on its wheels.

Le bac 10 peut également comprendre simplement la feuille souple 22 sans matériau alvéolaire 24 ou élastomère comprenant un groupe butyle.The tray 10 may also simply include the flexible sheet 22 without material alveolar 24 or elastomer comprising a butyl group.

La feuille souple 122 peut aussi être conformée pour être un sac pour la collecte de déchets du bac 100.The flexible sheet 122 may also be shaped to be a bag for the collection of waste from the tray 100.
