Description

L'invention concerne les bacs pour la collecte de déchets et plus particulièrement les bacs destinés à faciliter le tri sélectif.The invention relates to bins for the collection of waste and more particularly to bins intended to facilitate selective sorting.

En général, pour permettre à un utilisateur de trier ses déchets, on dispose, à proximité, plusieurs bacs qui sont chacun destinés à accueillir un type de déchets. Ainsi, de façon connue en soi, on dispose, en un même emplacement, un bac dont la fonction est de collecter les déchets principalement en verre, un bac dont la fonction est de collecter les déchets principalement en plastique et un bac dont la fonction est de collecter les déchets principalement en papier. Dans cette configuration, le nombre de bacs est relativement important.In general, to allow a user to sort his waste, there are several bins nearby which are each intended to accommodate a type of waste. Thus, in a manner known per se, there is, in the same location, a bin whose function is to collect mainly glass waste, a bin whose function is to collect mainly plastic waste and a bin whose function is to collect waste mainly in paper. In this configuration, the number of trays is relatively large.

Pour faciliter le tri sélectif, on utilise également des bacs pour la collecte de déchets qui comprennent au moins une paroi de séparation qui délimite plusieurs espaces distincts. Chaque espace est ainsi dédié à la collecte d'un type de déchets. Par exemple, l'un des espaces est dédié à la collecte du verre tandis que l'autre espace est destiné à recueillir du papier. Dans cette configuration, le nombre de bacs nécessaires pour permettre à l'utilisateur de trier ses déchets est plus réduit.To facilitate selective sorting, bins are also used for the collection of waste which include at least one dividing wall which delimits several distinct spaces. Each space is thus dedicated to the collection of a type of waste. For example, one of the spaces is dedicated to collecting glass while the other space is intended to collect paper. In this configuration, the number of bins required to allow the user to sort his waste is smaller.

Chacun de ces espaces est accessible à un utilisateur par l'intermédiaire d'un couvercle. Ainsi, le bac comprend au moins deux parties formant le couvercle, chacune des parties obturant (ou donnant accès) à un espace de stockage de déchets.Each of these spaces is accessible to a user via a cover. Thus, the bin comprises at least two parts forming the cover, each of the parts closing off (or giving access) to a waste storage space.

On connaît par exemple des bacs de collecte de déchets comprenant un couvercle en deux parties, les parties étant fixées sur des parois du bac de collecte opposées l'une à l'autre et se rejoignant au niveau de la paroi de séparation lorsque les deux parties obturent l'accès aux deux espaces de stockage de déchets. Le brevet FR 3 045 020 décrit quant à lui un bac de collecte de déchets comprenant deux parties montées mobiles en rotation au niveau de la paroi de séparation, avec deux axes de rotation parallèles entre eux.For example, waste collection bins are known comprising a cover in two parts, the parts being fixed to the walls of the collection bin opposite to each other and meeting at the level of the separation wall when the two parts block access to the two waste storage spaces. The patent FR 3 045 020 describes for its part a waste collection container comprising two parts mounted movable in rotation at the level of the partition wall, with two axes of rotation parallel to each other.

Cependant, ce type de bac peut présenter un inconvénient en termes de qualité de stockage des déchets.However, this type of bin can have a drawback in terms of the quality of waste storage.

En effet, ces derniers peuvent être stockés à l'extérieur et alors être exposés aux différentes conditions climatiques. En cas de pluie, de l'eau peut alors s'infiltrer au niveau de la zone où les deux parties du couvercle se rejoignent (ou interface entre les deux parties), qu'il s'agisse de la zone d'articulation des deux parties (comme pour le brevet FR 3 045 020 ) ou non (fixations des deux parties sur des parois opposées du bac de collecte).Indeed, these can be stored outside and then be exposed to different climatic conditions. In the event of rain, water can then infiltrate at the level of the area where the two parts of the cover meet (or interface between the two parts), whether it is the area of articulation of the two parts (as for the patent FR 3 045 020 ) or not (fixings of the two parts on opposite walls of the collection bin).

Dans le cas où les déchets contenus dans le bac comprennent du papier ou encore du carton, ces derniers peuvent être altérés et difficilement voire non exploitables dans le cadre d'un éventuel recyclage.In the event that the waste contained in the bin includes paper or even cardboard, the latter may be altered and difficult or even unusable in the context of possible recycling.

L'invention a notamment pour but de remédier ou de réduire l'inconvénient précité en fournissant un couvercle en deux parties empêchant l'infiltration d'eau entre les deux parties du couvercle.The object of the invention is in particular to remedy or reduce the aforementioned drawback by providing a cover in two parts preventing the infiltration of water between the two parts of the cover.

A cet effet l'invention a pour objet un bac de collecte de déchets comprenant :

  • une cuve,
  • au moins une paroi de séparation délimitant différents espaces de stockage de déchets dans la cuve, et
  • un couvercle formé d'un seul tenant et comprenant plusieurs portions, chaque portion recouvrant un espace de stockage de déchets différent, le couvercle comprenant au moins une zone déformable élastiquement formant une charnière pour au moins une portion du couvercle.
To this end, the subject of the invention is a waste collection bin comprising:
  • a tank,
  • at least one partition wall delimiting different waste storage spaces in the tank, and
  • a cover formed in one piece and comprising several portions, each portion covering a different waste storage space, the cover comprising at least one elastically deformable zone forming a hinge for at least a portion of the cover.

Ainsi, on réalise un couvercle en une seule partie pour un bac de collecte à plusieurs espaces de stockage. La ou les zones déformables élastiquement permettent de déplacer les portions du couvercle recouvrant les différents espaces de stockage afin de jeter les différents déchets.Thus, a cover is produced in a single part for a collection bin with several storage spaces. The elastically deformable zone or zones make it possible to move the portions of the cover covering the various storage spaces in order to dispose of the various waste.

On obtient ainsi un couvercle en une seule partie, ce qui élimine tout risque d'infiltration d'eau tout en permettant d'accéder facilement aux différents espaces de stockage de déchets.A cover is thus obtained in a single part, which eliminates any risk of water infiltration while allowing easy access to the various waste storage spaces.

Le bac de collecte de déchets selon l'invention peut en outre comprendre au moins une des caractéristiques suivantes :

  • une même zone déformable élastiquement permet le déplacement de plusieurs portions du couvercle,
  • la zone déformable élastiquement est formée par un matériau plus souple qu'un matériau formant le reste du couvercle,
  • la zone déformable élastiquement est formée par plusieurs plis de matière successifs,
  • la zone déformable élastiquement est formée d'une pièce sur laquelle les portions du couvercle sont surmoulées,
  • le couvercle est fixé sur la paroi de séparation,
  • la zone déformable élastiquement est fixée sur la paroi de séparation,
  • la zone déformable élastiquement s'étend de part et d'autre de la paroi de séparation, et
  • la zone déformable élastiquement est réalisée en polyéthylène basse densité.
The waste collection bin according to the invention can also include at least one of the following characteristics:
  • the same elastically deformable zone allows the displacement of several portions of the cover,
  • the elastically deformable zone is formed by a material that is softer than a material forming the rest of the cover,
  • the elastically deformable zone is formed by several successive folds of material,
  • the elastically deformable zone is formed from a part on which the portions of the cover are molded,
  • the cover is fixed on the partition wall,
  • the elastically deformable zone is fixed to the partition wall,
  • the elastically deformable zone extends on either side of the partition wall, and
  • the elastically deformable zone is made of low density polyethylene.

  • [Fig. 1] la figure 1 est une vue en perspective de la portion supérieure d'un bac de collecte de déchets comprenant un couvercle selon l'invention, et
  • [Fig. 2] la figure 2 est une vue en coupe du couvercle de la figure 1 en position ouverte.
The invention will be better understood on reading the description which will follow, given solely by way of example and made with reference to the appended drawings in which:
  • [ Fig. 1 ] the figure 1 is a perspective view of the upper portion of a waste collection bin comprising a cover according to the invention, and

Description détailléedetailed description

On se réfère désormais à la figure 1 représentant un bac de collecte de déchets 2 comprenant une cuve 4 et un couvercle 6.We now refer to the figure 1 showing a waste collection bin 2 comprising a tank 4 and a cover 6.

La cuve 4 comprend une ouverture (obturée par le couvercle 6 sur la figure 1), de forme sensiblement carrée (cette forme pouvant varier, par exemple en étant rectangulaire pour des bacs de collecte de déchets de grand volume), sur son extrémité supérieure, selon la direction verticale. De plus, la cuve 4 comporte, sur un contour délimitant l'ouverture, une collerette 7 qui permet de renforcer mécaniquement la cuve 4, notamment pour le soulevage lors du vidage du bac de collecte 2. En outre, la collerette 7 sert de support aux contours du couvercle 6. Sur une portion de cette collerette 7, au moins une poignée (non représentée) est fixée de façon à permettre une préhension facile du bac de collecte 2 par un opérateur.The tank 4 includes an opening (closed by the cover 6 on the figure 1 ), of substantially square shape (this shape may vary, for example by being rectangular for large volume waste collection bins), on its upper end, in the vertical direction. In addition, the tank 4 comprises, on an outline delimiting the opening, a collar 7 which makes it possible to mechanically reinforce the tank 4, in particular for lifting when emptying the collection tank 2. In addition, the collar 7 serves as a support. to the contours of the cover 6. On a portion of this flange 7, at least one handle (not shown) is fixed so as to allow easy gripping of the collection container 2 by an operator.

La partie inférieure, selon la direction verticale, de la cuve 4 peut être de tout type. Le bac de collecte 2 peut notamment comprendre une ou plusieurs roues. En outre, la cuve 4 est ici essentiellement constituée de plastique, par exemple 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 4 peut être issue d'un procédé de moulage par injection, elle est monobloc.The lower part, in the vertical direction, of the tank 4 can be of any type. The collection bin 2 can in particular include one or more wheels. In addition, the tank 4 is here essentially made of plastic, for example polyethylene, preferably partially or fully recycled, but may, according to a variant of the present embodiment, comprise another plastic material or metal. The tank 4 can be obtained from an injection molding process, it is in one piece.

La cuve 4 comprend deux espaces de stockage séparés par l'intermédiaire d'une paroi de séparation 8 (visible sur la figure 2).The tank 4 comprises two separate storage spaces by means of a partition wall 8 (visible on the figure 2 ).

Les dimensions de la paroi de séparation 8 sont adaptées pour qu'elle définisse, dans la cuve 4, deux espaces de stockage qui ne communiquent pas l'un envers l'autre et de sorte qu'un déchet, même de taille réduite, introduit dans l'un des espaces de stockage ne puisse rejoindre l'autre espace de stockage, même lorsque le bac de collecte 2 est retourné, pour être par exemple vidé.The dimensions of the partition wall 8 are adapted so that it defines, in the tank 4, two storage spaces which do not communicate with each other and so that waste, even of small size, introduces in one of the storage spaces cannot join the other storage space, even when the collection bin 2 is turned upside down, for example to be emptied.

Le volume des deux espaces de stockage peut être équivalent. Alternativement, la paroi de séparation 12 peut être placée dans la cuve de manière à ce que l'un des espaces de stockage soit plus important que l'autre, par exemple parce qu'il est destiné à recevoir des déchets de volume plus important ou encore dont la quantité produite par un ménage est plus importante.The volume of the two storage spaces can be equivalent. Alternatively, the partition wall 12 can be placed in the tank so that one of the storage spaces is larger than the other, for example because it is intended to receive waste of greater volume or still the quantity produced by a household is more important.

Bien entendu, il est possible qu'il y ait plus d'une paroi de séparation délimitant plus de deux espaces de stockage de déchets. On peut par exemple envisager une cuve comprenant quatre espaces de stockage. Dans ce qui va suivre, nous décrirons une configuration à une paroi de séparation et deux espaces de stockage.Of course, it is possible that there is more than one partition wall delimiting more than two waste storage spaces. One can for example consider a tank comprising four storage spaces. In what follows, we will describe a configuration with one partition wall and two storage spaces.

Le couvercle 6 est réalisé d'un seul tenant (i.e. en une seule partie, contrairement à un couvercle selon l'art antérieur mentionné ci-dessus dans lequel le couvercle est réalisé en plusieurs parties articulées, chaque partie étant assimilable à un couvercle). Il recouvre l'ouverture du bac de collecte 2 et donc les deux espaces de stockage.The cover 6 is made in one piece (i.e. in a single part, unlike a cover according to the prior art mentioned above in which the cover is made in several articulated parts, each part being comparable to a cover). It covers the opening of the collection bin 2 and therefore the two storage spaces.

Plus précisément, chaque espace de stockage est obturé par une portion du couvercle 6. Dans l'exemple illustré, le couvercle 6 comprend deux portions 10 et 12 (car il y a deux espaces de stockage), chaque portion recouvrant un espace de stockage. Le nombre de portions peut varier, notamment en fonction du nombre d'espaces de stockage de déchets (le nombre de portions peut être identique ou différent du nombre d'espaces de stockage de déchets).More precisely, each storage space is closed off by a portion of the cover 6. In the example illustrated, the cover 6 comprises two portions 10 and 12 (because there are two storage spaces), each portion covering a storage space. The number of portions may vary, in particular depending on the number of waste storage spaces (the number of portions may be the same or different from the number of waste storage spaces).

Afin de pouvoir déplacer les portions 10 et 12 du couvercle 6 entre une position d'obturation de l'espace de stockage qu'elle recouvre et une position dans laquelle ledit espace de stockage est accessible à un utilisateur (i.e. entre une position fermée et ouverte), le couvercle 6 comprend au moins une zone déformable élastiquement (une seule zone déformable élastiquement 14 dans l'exemple illustré) formant une charnière pour au moins une des portions 10 et 12 du couvercle 6. Dans l'exemple illustré, une même zone déformable élastiquement 14 forme une charnière pour les deux portions 10 et 12 du couvercle 6. Cela est visible sur la figure 2 dans laquelle les deux portions 10 et 12 du couvercle 6 sont représentées relevées.In order to be able to move the portions 10 and 12 of the cover 6 between a closed position of the storage space that it covers and a position in which said storage space is accessible to a user (ie between a closed and open position ), the cover 6 comprises at least one elastically deformable zone (a single elastically deformable zone 14 in the example illustrated) forming a hinge for at least one of the portions 10 and 12 of the cover 6. In the example illustrated, the same zone elastically deformable 14 forms a hinge for the two portions 10 and 12 of the cover 6. This is visible on the figure 2 in which the two portions 10 and 12 of the cover 6 are shown raised.

Dans l'exemple illustré sur les figures, la zone déformable élastiquement est formée de plusieurs plis de matière successifs. Ces plis de matières, assimilables à une structure en accordéon, permettent une déformation facile du couvercle 6 et donc un déplacement aisé des portions 10 et 12.In the example illustrated in the figures, the elastically deformable zone is formed of several successive folds of material. These folds of materials, similar to an accordion structure, allow easy deformation of the cover 6 and therefore easy movement of the portions 10 and 12.

Il est possible que la zone déformable élastiquement 14 soit réalisée dans un matériau plus souple qu'un matériau formant le reste du couvercle 6. Dès lors, il est possible que la zone charnière soit plus facilement déformable que le reste du couvercle (dont les portions 10 et 12 font parties) qui peut avoir une rigidité suffisante pour supporter le poids d'un corps étranger, par exemple de la neige s'étant accumuler sur le couvercle. Il est par exemple possible que la zone déformable élastiquement 14 soit réalisée en polyéthylène basse densité (PE-LD) et le reste du couvercle en polyéthylène (PE).It is possible that the elastically deformable zone 14 is made of a material that is softer than a material forming the rest of the cover 6. Consequently, it is possible that the hinge zone is more easily deformable than the rest of the cover (including the portions 10 and 12 are part) which may have sufficient rigidity to support the weight of a foreign body, for example snow having accumulated on the lid. It is for example possible that the elastically deformable zone 14 is made of low density polyethylene (PE-LD) and the rest of the cover of polyethylene (PE).

Alternativement, tout le couvercle 6 peut être réalisé en utilisant un même matériau, par exemple le polyéthylène basse densité. L'utilisation d'un seul matériau rend le procédé de fabrication plus simple, le couvercle 6 étant également facilement recyclable.Alternatively, the entire cover 6 can be made using the same material, for example low density polyethylene. The use of a single material makes the manufacturing process simpler, the cover 6 also being easily recyclable.

Il est possible d'apporter de la rigidité aux portions 10 et 12 en donnant une forme particulière à ces dernières, par exemple par la présence de nervures.It is possible to bring rigidity to the portions 10 and 12 by giving a particular shape to the latter, for example by the presence of ribs.

Il est possible de fixer le couvercle 6 sur la paroi de séparation 8 afin de se passer de pièces supplémentaires à placer entre le couvercle 6 et la paroi de séparation 8. Cela est possible car le couvercle comprend des zones formant naturellement des charnières, il n'y a donc pas de nécessité d'équiper le bac de collecte 2 avec des moyens permettant la rotation du couvercle 6.It is possible to fix the cover 6 on the dividing wall 8 in order to dispense with additional parts to be placed between the cover 6 and the dividing wall 8. This is possible because the cover includes areas naturally forming hinges, it is not possible. 'There is therefore no need to equip the collection container 2 with means allowing the rotation of the cover 6.

La fixation du couvercle 6 sur la paroi de séparation 8 peut par exemple être réalisée par rivetage ou tout autre moyen connu de l'homme du métier.The fixing of the cover 6 on the partition wall 8 can for example be carried out by riveting or any other means known to those skilled in the art.

Il est possible de fixer la zone déformable élastiquement 14 à la paroi de séparation 8, comme cela est visible sur les figures. Dans l'exemple illustré sur ces dernières, la zone déformable élastiquement 14 s'étend sur toute la longueur du couvercle 6. Sa direction d'extension est parallèle à l'extrémité supérieure de la paroi de séparation 8 en s'étendant, de manière égale ou non, de part et d'autre de cette dernière. Ainsi, on obtient un bac de collecte 2 comprenant un couvercle 6 dont les portions 10 et 12 peuvent être déplacés en rotation en donnant accès à l'intégralité des espaces de stockage. Un autre avantage de cette fixation réside dans le fait que l'encombrement lié au débattement des portions 10 et 12 est limité à la surface au sol du bac de collecte 2.It is possible to fix the elastically deformable zone 14 to the partition wall 8, as can be seen in the figures. In the example illustrated on the latter, the elastically deformable zone 14 extends over the entire length of the cover 6. Its direction of extension is parallel to the upper end of the partition wall 8 while extending so equal or not, on both sides of the latter. Thus, a collection container 2 is obtained comprising a cover 6, the portions 10 and 12 of which can be moved in rotation, giving access to all of the storage spaces. Another advantage of this fixing resides in the fact that the bulk associated with the movement of the portions 10 and 12 is limited to the floor area of the collection bin 2.

Concernant la fabrication du couvercle 6, plusieurs procédés peuvent être mis en œuvre.Regarding the manufacture of the cover 6, several methods can be implemented.

Tout d'abord, il est possible de mouler le couvercle 6 par l'injection d'une seule matière plastique, par exemple celles citées ci-dessus, dans un moule d'injection ayant la forme du couvercle 6. Il s'agit d'un procédé classiquement utilisé et connu de l'homme du métier.First of all, it is possible to mold the cover 6 by injecting a single plastic material, for example those mentioned above, into an injection mold having the shape of the cover 6. It is a question of a method conventionally used and known to those skilled in the art.

Alternativement, et par exemple dans le cas où la zone déformable élastiquement 14 est réalisée dans un matériau différent de celui du reste du couvercle 6, il est possible :

  • De fabriquer dans un premier temps, par exemple par moulage, la zone déformable élastiquement 14 puis de placer cette dernière dans le moule du couvercle 6 afin de surmouler le reste du couvercle 6 sur cette dernière. Il est également possible de mettre en œuvre ce procédé si la zone déformable élastiquement 14 est réalisée dans un matériau identique au reste du couvercle 6 mais comprend une architecture particulière ne pouvant être réalisée en utilisant le moule du couvercle 6 ;
  • De fabriquer le couvercle 6 en utilisant un moule de bi-injection (ou injection bi-matière) dans lequel deux matières plastiques différentes sont injectées (à partir de deux circuits d'injection différents) afin de réaliser dans le même moule la zone déformable élastiquement 14 et le reste du couvercle 6.
Alternatively, and for example in the case where the elastically deformable zone 14 is made of a material different from that of the rest of the cover 6, it is possible:
  • To manufacture initially, for example by molding, the elastically deformable zone 14 then to place the latter in the mold of the cover 6 in order to mold the rest of the cover 6 onto the latter. It is also possible to implement this method if the elastically deformable zone 14 is made of a material identical to the rest of the cover 6 but comprises a particular architecture that cannot be produced using the mold of the cover 6;
  • To manufacture the cover 6 using a bi-injection mold (or bi-material injection) in which two different plastics are injected (from two different injection circuits) in order to produce the elastically deformable zone in the same mold 14 and the rest of the cover 6.

L'invention n'est pas limitée aux modes de réalisation présentés et d'autres modes de réalisation apparaîtront clairement à l'homme du métier. Il est notamment possible d'utiliser des matériaux autres que ceux envisagés ci-dessus.The invention is not limited to the embodiments presented and other embodiments will be apparent to those skilled in the art. It is in particular possible to use materials other than those envisaged above.

Le nombre de parois de séparation, d'espaces de stockage, de portions du couvercle ou encore de zones déformables élastiquement peut également varier.The number of partition walls, storage spaces, portions of the cover or else elastically deformable zones can also vary.

Les dimensionnements des différentes pièces peuvent également être différents de ceux visibles ci-dessus.The dimensions of the different parts may also be different from those visible above.
