Description

La présente invention concerne un bac pour la collecte de déchets.The present invention relates to a bin for collecting waste.

L'invention concerne plus particulièrement un bac comportant une cuve et un couvercle pivotant, mobile entre une position d'ouverture dans laquelle il permet l'introduction de déchets dans la cuve et une position de fermeture dans laquelle il repose par sa périphérie sur la cuve.The invention relates more particularly to a container comprising a tank and a pivoting cover, movable between an open position in which it allows the introduction of waste into the tank and a closed position in which it rests by its periphery on the tank.

De tels bacs sont habituellement munis de roues.Such bins are usually fitted with wheels.

Pour réduire les nuisances sonores, la cuve et/ou le couvercle de certains bacs connus sont munis de butées en caoutchouc qui permettent d'amortir les chocs du couvercle sur la cuve.To reduce noise pollution, the tank and / or the lid of certain bins known are provided with rubber stops which make it possible to absorb the shocks of the cover on the tank.

Il a également été proposé de réaliser un frein au niveau de l'articulation du couvercle sur la cuve afin de ralentir le mouvement de ce dernier à l'approche des positions de fermeture et d'ouverture.It has also been proposed to brake the articulation of the cover on the tank in order to slow the movement of the latter when approaching closing and opening positions.

Un tel frein est relativement délicat à réaliser et de plus son efficacité diminue au cours de la vie du bac, du fait de l'usure des parties en contact.Such a brake is relatively difficult to achieve and moreover its effectiveness decreases during the life of the tank, due to the wear of the parts in contact.

Il est déjà connu par US-A-4 917 257 de freiner un couvercle de conteneur à déchets en prévoyant sur la cuve une nervure en saillie vers le haut de la cuve du conteneur pour former, en coopération avec le bord du couvercle, un trajet d'air en labyrinthe lors de la fermeture du bac.It is already known by US-A-4,917,257 to brake a container cover at waste by providing on the tank a rib projecting towards the top of the tank container to form, in cooperation with the edge of the cover, an air path in labyrinth when closing the bin.

Il s'est avéré que cette caractéristique ne permet pas un freinage suffisant et ne réduit pas sensiblement le bruit créé par l'impact du couvercle sur la cuve.It turned out that this characteristic does not allow sufficient braking and does not not significantly reduce the noise created by the impact of the cover on the tank.

L'invention vise à réduire notablement le bruit de fermeture du couvercle d'une manière simple, efficace et constante tout au long de la vie du bac.The invention aims to significantly reduce the closing noise of the cover of a simple, efficient and consistent throughout the life of the tank.

Elle y parvient par le fait que le couvercle et la cuve sont agencés de telle sorte que l'air sortant de la cuve lors de la fermeture du couvercle et lorsque ce dernier est proche de sa position de fermeture est forcé à faire au moins deux virages, en étant forcé à passer entre des surfaces sensiblement verticales appartenant respectivement au couvercle et à la cuve, au moins du côté avant du couvercle, et de préférence au moins du côté avant du couvercle et sur ses deux côtés latéraux, et de préférence encore le long des quatre côtés du couvercle, afin de favoriser la création d'une surpression dans la cuve, surpression qui tend à freiner le déplacement du couvercle vers sa position de fermeture.It does this by the fact that the cover and the tank are arranged in such a way that the air leaving the tank when the lid is closed and when the latter is close to its closed position is forced to make at least two turns, being forced to pass between substantially vertical surfaces belonging respectively to the cover and to the tank, at least on the front side of the cover, and preferably at least on the front side of the cover and on its two lateral sides, and preferably still along on the four sides of the cover, in order to favor the creation of an overpressure in the tank, overpressure which tends to slow the movement of the cover to its position closing.

Grâce à l'invention, on réalise un freinage efficace du couvercle sans avoir à rapporter sur la cuve ou le couvercle des butées en caoutchouc.Thanks to the invention, an efficient braking of the cover is carried out without having to put rubber stops on the tank or the cover.

Dans le cas où de telles butées sont quand même utilisées, l'invention procure néanmoins des avantages puisque la vitesse du couvercle lorsque ce dernier atteint sa position de fermeture est moindre, de sorte que les butées précitées sont moins sollicitées et peuvent être de taille réduite.In the case where such stops are still used, the invention provides nevertheless advantages since the speed of the cover when the latter reaches its closing position is less, so that the abovementioned stops are less requested and may be reduced in size.

De plus, dans l'invention, l'intensité du freinage est d'autant plus grande que le couvercle est rabattu violemment sur la cuve.In addition, in the invention, the intensity of the braking is all the greater as the lid is folded back violently on the tank.

De préférence, les deux surfaces verticales entre lesquelles l'air est forcé à passer et qui appartiennent respectivement au couvercle et à la cuve, sont distantes de moins de 50 mm.Preferably, the two vertical surfaces between which air is forced to pass and which belong respectively to the cover and to the tank, are distant from less than 50 mm.

Le couvercle comporte avantageusement une jupe ou paroi intérieure sur sa surface intérieure, cette paroi intérieure étant de préférence conformée pour s'engager à l'intérieur de la cuve lorsque le bac est fermé.The cover advantageously has a skirt or inner wall on its inner surface, this inner wall preferably being shaped to commit to inside the tank when the tank is closed.

L'écartement entre cette jupe ou paroi intérieure et les parois principales de la cuve, lorsque le bac est fermé, est par exemple compris entre 2 mm et 50 mm.The spacing between this skirt or interior wall and the main walls of the tank, when the tank is closed, is for example between 2 mm and 50 mm.

Avantageusement, la jupe ou paroi intérieure présente une hauteur suffisante pour commencer à s'opposer au départ de l'air contenu entre la cuve et le couvercle lorsque le couvercle est en cours de fermeture et que l'angle d'ouverture est voisin de 2,5°.Advantageously, the skirt or inner wall has a sufficient height to begin to oppose the departure of the air contained between the tank and the cover when the cover is being closed and the opening angle is close to 2.5 °.

La hauteur de la jupe ou paroi intérieure, le long du côté avant du couvercle, est par exemple comprise entre 1 et 8 cm.The height of the skirt or inner wall, along the front side of the cover, is for example between 1 and 8 cm.

Le bac peut comporter comme dans le document US-A-4 917 257 une nervure disposée dans le prolongement des parois principales de la cuve, autour de l'ouverture de cette dernière.The container may include, as in document US-A-4,917,257, a rib arranged in the extension of the main walls of the tank, around the opening of the latter.

Cette nervure s'étend avantageusement autour de la jupe ou paroi intérieure précitée lorsque le bac est fermé.This rib advantageously extends around the skirt or inner wall above when the bin is closed.

La hauteur de la nervure précitée, le long du côté avant du couvercle, est par exemple comprise entre 0 et 3 cm.The height of the aforementioned rib, along the front side of the cover, is by example between 0 and 3 cm.

Avantageusement, le couvercle comporte une jupe extérieure.Advantageously, the cover has an outer skirt.

Cette jupe extérieure s'étend de préférence autour de la nervure susdite lorsque le bac est fermé.This outer skirt preferably extends around the aforementioned rib when the bin is closed.

La jupe ou paroi intérieure du couvercle présente avantageusement le long des côtés latéraux du couvercle une hauteur variable, augmentant vers l'avant au moins à partir d'une région médiane du couvercle située à mi-distance entre ses côtés avant et arrière.The skirt or inner wall of the cover advantageously has along the lateral sides of the cover a variable height, increasing forward at least at from a central region of the cover located midway between its front sides and back.

Ainsi, lorsque le couvercle est dans sa position d'ouverture, en appui contre la paroi arrière de la cuve, et que le bac est basculé par le mécanisme de levage d'un véhicule de collecte pour vider son contenu, le risque d'accrochage du couvercle sur un organe du mécanisme de levage est réduit.Thus, when the cover is in its open position, pressing against the rear wall of the tank, and the tank is tilted by the lifting mechanism of a collection vehicle to empty its contents, the risk of catching the cover on a organ of the lifting mechanism is reduced.

Dans une réalisation particulière, la jupe ou paroi intérieure présente le long des côtés latéraux du couvercle une hauteur croissante depuis le voisinage du bord arrière du couvercle vers le bord avant du couvercle.In a particular embodiment, the skirt or inner wall has along on the lateral sides of the cover an increasing height from the vicinity of the edge back of the cover to the front edge of the cover.

Dans une autre réalisation particulière, la jupe ou paroi intérieure présente le long de deux côtés opposés du couvercle, de préférence ses deux côtés latéraux, un profil arrondi, concave vers la cuve lorsque le bac est fermé et la paroi supérieure du couvercle présente une forme convexe vers l'extérieur, ce profil étant choisi de manière à faciliter le gerbage des couvercles avant leur montage sur les cuves des bacs.In another particular embodiment, the skirt or inner wall has the along two opposite sides of the cover, preferably its two lateral sides, a rounded profile, concave towards the tank when the tank is closed and the upper wall of the cover has a convex shape towards the outside, this profile being chosen so to facilitate the stacking of the covers before their mounting on the tanks of the tanks.

Le bac peut comporter une collerette sur laquelle la jupe extérieure du couvercle repose quand le bac est fermé.The container may include a collar on which the outer skirt of the cover rests when container is closed.

Cette collerette peut comporter, au moins à l'avant du bac, un rebord dirigé vers le bas.This collar may include, at least at the front of the tank, a flange directed towards the bottom.

The invention will be better understood on reading the detailed description which follows, of nonlimiting exemplary embodiments, and on examining the appended drawing in which:
  • FIG. 1 is a schematic view, in section, of a container according to the invention,
  • FIG. 2 corresponds to detail II of FIG. 1, when the cover is about to reach its closed position,
  • FIG. 3 is a partial section of a lateral side of the cover along the section line III of FIG. 1, when the cover has reached its closed position,
  • FIGS. 4 to 16 illustrate different configurations of the cover and of the tank,

  • Figure 20 is a detail view of another alternative embodiment.

Le bac 1 représenté sur la figure 1 comporte une cuve 2 et un couvercle 3 articulé par son côté arrière 4 sur la cuve 2 autour d'un axe géométrique de rotation horizontal.The tank 1 shown in Figure 1 has a tank 2 and a cover 3 articulated by its rear side 4 on the tank 2 around a geometric axis of rotation horizontal.

La cuve 2 et le couvercle 3 sont réalisés en matière plastique.The tank 2 and the cover 3 are made of plastic.

Le bac 1 est muni de roues 5 au nombre de deux dans l'exemple de réalisation décrit.Tray 1 is provided with wheels 5, two in number in the exemplary embodiment described.

Le bac 1 comporte une collerette extérieure 6 s'étendant sur tout le pourtour de la partie supérieure de la cuve 2.The tank 1 has an external collar 6 extending around the entire periphery of the upper part of the tank 2.

La collerette 6 comporte une paroi plane horizontale terminée à sa périphérie par un rebord 7 dirigé vers le bas.The collar 6 has a horizontal flat wall terminated at its periphery by a flange 7 directed downwards.

Ce rebord 7 présente à l'avant du bac une forme adaptée à recevoir les extrémités des peignes d'un mécanisme de levage d'un véhicule de collecte.This rim 7 has at the front of the tank a shape adapted to receive the ends of the combs of a lifting mechanism of a collection vehicle.

Le bac 1 est vidé en étant basculé vers l'avant, c'est-à-dire dans le sens de la flèche V de la figure 1.Tray 1 is emptied by being tilted forward, that is to say in the direction of arrow V in Figure 1.

Lorsque le bac 1 est ouvert, le couvercle 3 repose contre la paroi arrière 8 de la cuve 2.When the tray 1 is open, the cover 3 rests against the rear wall 8 of the tank 2.

Pour éviter que le couvercle 3, en étant refermé sur la cuve 2, génère un bruit important, des moyens de freinage du mouvement de fermeture du couvercle sont prévus.To prevent the cover 3, by being closed on the tank 2, generating a noise important, means for braking the movement of closing the cover are planned.

Ces moyens de freinage sont agencés de manière à ralentir l'écoulement de l'air emprisonné dans la cuve 2 sous le couvercle 3 lors de la fermeture du bac 1, et peuvent présenter diverses formes de réalisation sans que l'on sorte du cadre de la présente invention.These braking means are arranged so as to slow the flow of air trapped in the tank 2 under the cover 3 when the tank 1 is closed, and can present various embodiments without departing from the scope of this invention.

On a représenté sur les figures 2 à 16 plusieurs exemples de réalisation.Several embodiment examples are shown in FIGS. 2 to 16.

Toutes ces figures sont schématiques et les proportions et positionnement relatifs des divers éléments n'ont pas été nécessairement respectés dans un souci de clarté du dessin.All these figures are schematic and the proportions and positioning relative of the various elements were not necessarily respected for the sake of clarity of the drawing.

Ainsi, les passages formés entre le couvercle et la cuve pour permettre à l'air de s'écouler pourront être plus étroits dans la réalité que sur le dessin.Thus, the passages formed between the cover and the tank to allow the air to flow may be narrower in reality than in the drawing.

Dans l'exemple de la figure 2, le couvercle 3 comporte une paroi supérieure 30 légèrement bombée, pourvue à sa périphérie d'une jupe extérieure 31 dirigée vers le bas lorsque le bac est fermé.In the example of Figure 2, the cover 3 has an upper wall 30 slightly rounded, provided at its periphery with an outer skirt 31 directed downwards when the bin is closed.

Cette jupe extérieure 31 vient en appui, par son extrémité inférieure 32, sur la collerette 6 lorsque le bac 1 est fermé.This outer skirt 31 comes to bear, by its lower end 32, on the collar 6 when tray 1 is closed.

Une jupe intérieure 33, tubulaire, fait saillie sur la face intérieure de la paroi supérieure 30 du couvercle 3.An inner skirt 33, tubular, protrudes from the inner face of the wall top 30 of cover 3.

Cette jupe intérieure 33 s'étend verticalement lorsque le bac 1 est fermé et s'engage alors dans la cuve 2.This inner skirt 33 extends vertically when the tray 1 is closed and then engages in the tank 2.

Les parois principales de la cuve 2 sont prolongées vers le haut, au-dessus de la collerette 6, par une nervure 9, laquelle borde l'ouverture de la cuve 2.The main walls of the tank 2 are extended upwards, above the flange 6, by a rib 9, which borders the opening of the tank 2.

La jupe intérieure 33 du couvercle vient se placer en regard et à faible distance de la nervure 9 lorsque le bac 1 est fermé.The inner skirt 33 of the cover is placed opposite and at a short distance of the rib 9 when the tray 1 is closed.

De préférence, l'écartement entre la nervure 9 et la jupe intérieure 33, quand le bac 1 est fermé, est inférieur à 50 mm.Preferably, the spacing between the rib 9 and the inner skirt 33, when the tray 1 is closed, is less than 50 mm.

De préférence également, l'écartement entre la jupe extérieure 31 et la nervure 9 est inférieur à 50 mm quand le bac 1 est fermé.Also preferably, the spacing between the outer skirt 31 and the rib 9 is less than 50 mm when tray 1 is closed.

Les jupes extérieure 31 et intérieure 33 et la nervure 9 constituent, le long des côtés avant, arrière et latéraux du couvercle 3, une chicane qui force l'air chassé dans la cuve 2 par la fermeture du couvercle 3 à effectuer des détours avant de pouvoir gagner l'extérieur.The outer 31 and inner 33 skirts and the rib 9 constitute, along the front, rear and side of the cover 3, a baffle that forces the air expelled into the tank 2 by closing the cover 3 to make detours before being able to win outside.

La nervure 9 de ce mode de réalisation n'est que facultative et l'effet de chicane à deux virages pour l'air peut être obtenu, dans une variante non représentée, autour de la jupe intérieure 33 et autour de l'extrémité inférieure 32 de la jupe extérieure 31.The rib 9 of this embodiment is only optional and the effect of baffle with two bends for the air can be obtained, in a variant not shown, around the inner skirt 33 and around the lower end 32 of the outer skirt 31.

On voit sur la figure 3 que la nervure 9 s'engage entre les jupes intérieure 33 et extérieure 31 le long des côtés latéraux du couvercle 3, lorsque le bac 1 est fermé.We see in Figure 3 that the rib 9 engages between the inner skirts 33 and outside 31 along the lateral sides of the cover 3, when the tank 1 is closed.

Le mouvement de l'air lors de la fermeture du couvercle 3 est illustré par des flèches sur la figure 2.The movement of air when the cover 3 is closed is illustrated by arrows in Figure 2.

On comprend que l'air est forcé à contourner par le bas la jupe intérieure 33, dont la hauteur à l'avant du couvercle 3 est par exemple de 35 mm avant de remonter dans l'espace de faible épaisseur ménagé entre la jupe intérieure 33 et la nervure 9, puis d'être dévié à nouveau vers le bas par la jupe extérieure 31 avant de pouvoir s'échapper par l'intervalle laissé entre le bord inférieur 32 de la jupe extérieure 31 et la collerette 6.We understand that the air is forced to bypass the inner skirt 33 from below, whose height at the front of the cover 3 is for example 35 mm before reassembling in the thin space formed between the inner skirt 33 and the rib 9, then to be deflected down again by the outer skirt 31 before being able to escape by the gap left between the lower edge 32 of the outer skirt 31 and the collar 6.

Ainsi, le mouvement de fermeture du couvercle 3 ramène plus d'air dans la cuve 2 qu'il ne peut s'en échapper par l'intervalle entre le couvercle 3 et la cuve, ce qui tend à créer une surpression momentanée dans la cuve 2, surpression qui freine le déplacement du couvercle 3.Thus, the closing movement of the cover 3 brings more air into the tank 2 that it cannot escape through the gap between the cover 3 and the tank, which tends to create a temporary overpressure in the tank 2, overpressure which brakes the moving the cover 3.

Le couvercle 3 est donc ralenti avant d'atteindre sa position de fermeture (appui du couvercle sur la nervure 9) et le bruit généré par le choc du couvercle 3 sur la cuve 2 est diminué.The cover 3 is therefore slowed down before reaching its closed position (press of the cover on the rib 9) and the noise generated by the impact of the cover 3 on the tank 2 is decreased.

L'exemple de réalisation de la figure 4 se distingue du précédent par l'absence de jupe intérieure 33 et par la présence d'une deuxième nervure 11, parallèle à la nervure 9, la jupe extérieure 31 venant s'engager entre les nervures 9 et 11.The embodiment of Figure 4 differs from the previous one by the absence inner skirt 33 and by the presence of a second rib 11, parallel to the rib 9, the outer skirt 31 engaging between the ribs 9 and 11.

La hauteur de la nervure 11 est comprise par exemple entre 2 et 50 mm.The height of the rib 11 is for example between 2 and 50 mm.

L'épaisseur de la jupe 31 est de 4 mm par exemple.The thickness of the skirt 31 is 4 mm for example.

L'écartement entre les nervures 9 et 11 est compris par exemple entre 5 et 100 mm. The spacing between the ribs 9 and 11 is for example between 5 and 100 mm.

L'exemple de réalisation de la figure 5 se distingue du précédent par la présence supplémentaire d'une jupe intérieure 33, à l'instar du mode de réalisation de la figure 2.The example of embodiment in FIG. 5 differs from the previous one by the additional presence of an inner skirt 33, like the embodiment of the figure 2.

Dans l'exemple de réalisation de la figure 6, le bac comporte des nervures 9 et 11, tout comme celui de la figure 5, et le couvercle 3 comporte des jupes extérieure 41 et intérieure 43.In the embodiment of FIG. 6, the tank has ribs 9 and 11, like that of FIG. 5, and the cover 3 comprises external skirts 41 and interior 43.

La collerette 6 est relativement large.The collar 6 is relatively wide.

La jupe extérieure 41 vient en appui sur la collerette 6, lorsque le bac est fermé, à l'extérieur de la nervure 11 et la jupe intérieure 43 s'engage alors entre les nervures 9 et 11.The outer skirt 41 comes to bear on the collar 6, when the tray is closed, outside the rib 11 and the inner skirt 43 then engages between the ribs 9 and 11.

L'écartement entre la jupe extérieure 41 et la nervure 11 est par exemple compris entre 2 et 50 mm.The spacing between the outer skirt 41 and the rib 11 is for example between 2 and 50 mm.

L'écartement entre la jupe intérieure 43 et la nervure 11 est par exemple compris entre 2 et 50 mm.The spacing between the inner skirt 43 and the rib 11 is for example between 2 and 50 mm.

L'écartement entre la nervure 9 et la jupe intérieure 43 est par exemple compris entre 2 et 50 mm.The spacing between the rib 9 and the inner skirt 43 is for example included between 2 and 50 mm.

Dans l'exemple de réalisation de la figure 7, la collerette 6 n'est pas prolongée par un rebord 7 vers le bas, à l'instar des exemples de réalisation des figures 2 à 6, mais comporte une partie périphérique 44 ayant en section une forme de Γ.In the embodiment of Figure 7, the flange 6 is not extended by a flange 7 downwards, like the exemplary embodiments of FIGS. 2 to 6, but comprises a peripheral part 44 having in section a shape of Γ.

Cette partie périphérique 44 définit avec la nervure 9 une gorge 45 ouverte vers le haut, dans laquelle vient s'engager la jupe extérieure 31 du couvercle lorsque le bac 1 est fermé.This peripheral part 44 defines with the rib 9 a groove 45 open towards the top, in which the outer skirt 31 of the cover engages when the container 1 is closed.

La largeur de la gorge 45 est comprise par exemple entre 2 et 100 mm.The width of the groove 45 is for example between 2 and 100 mm.

Ainsi, l'écart entre la jupe extérieure 31 et chacun des montants de la collerette 6 délimitant la gorge 45 est compris entre 2 et 100 mm.Thus, the gap between the outer skirt 31 and each of the uprights of the collar 6 delimiting the groove 45 is between 2 and 100 mm.

L'exemple de réalisation de la figure 8 diffère de celui de la figure 7 par la présence de la jupe intérieure 33, conformée pour s'engager dans la cuve 2.The embodiment of FIG. 8 differs from that of FIG. 7 by the presence of the inner skirt 33, shaped to engage in the tank 2.

L'écart entre la jupe intérieure 33 et la nervure 9 est par exemple compris entre 2 et 50 mm.The distance between the inner skirt 33 and the rib 9 is for example between 2 and 50 mm.

Dans l'exemple de réalisation de la figure 9, la collerette 6 est terminée par une partie périphérique 50 ayant en section une forme de créneau.In the embodiment of Figure 9, the flange 6 is terminated by a peripheral part 50 having in section a niche shape.

Le couvercle comporte une jupe extérieure 51 et une jupe intérieure 52 qui viennent respectivement de part et d'autre de cette partie 50 lorsque le couvercle est fermé.The cover has an outer skirt 51 and an inner skirt 52 which come respectively from both sides of this part 50 when the cover is closed.

L'écartement entre chacune des jupes 51 et 52 et cette partie 50 est par exemple compris entre 1 et 15 cm.The spacing between each of the skirts 51 and 52 and this part 50 is for example between 1 and 15 cm.

Le mode de réalisation de la figure 10 est assez proche de celui de la figure 4 et n'en diffère que par l'absence de rebord 7, la collerette 6 se terminant par la nervure 11.The embodiment of FIG. 10 is fairly close to that of FIG. 4 and differs from it only by the absence of a rim 7, the collar 6 ending in the rib 11.

Dans le mode de réalisation de la figure 11, la collerette est étagée et comporte, de l'extérieur vers l'intérieur, des première 60 et seconde 61 marches, la dernière étant plus haute que la première.In the embodiment of FIG. 11, the collar is stepped and includes, from outside to inside, first 60 and second 61 steps, the last one being higher than the first.

La collerette est pourvue à sa périphérie d'un rebord 62 dirigé vers le bas.The flange is provided at its periphery with a flange 62 directed downwards.

Le couvercle comporte une jupe extérieure 63 et une jupe intérieure 64.The cover has an outer skirt 63 and an inner skirt 64.

L'écartement entre ces dernières est compris par exemple entre 1 et 15 cm.The spacing between the latter is for example between 1 and 15 cm.

La jupe extérieure 63 vient reposer sur la première marche 60 lorsque le couvercle est fermé, tandis que la jupe intérieure 64 vient se positionner à une faible distance de la paroi intérieure de la cuve.The outer skirt 63 comes to rest on the first step 60 when the cover is closed, while the inner skirt 64 is positioned at a low distance from the inner wall of the tank.

L'écart entre la jupe extérieure 63 et le nez de la deuxième marche 61 est par exemple compris entre 2 et 50 mm.The distance between the outer skirt 63 and the nose of the second step 61 is by example between 2 and 50 mm.

Dans l'exemple de réalisation de la figure 12, le couvercle présente une forme similaire à celle du couvercle de la figure 6, avec des jupes extérieure 41 et intérieure 43.In the embodiment of Figure 12, the cover has a shape similar to that of the cover of FIG. 6, with external skirts 41 and internal 43.

Par rapport à l'exemple de réalisation de la figure 6, le bac 1 ne comporte pas de nervure 9 et la collerette 6 ne comporte pas de nervure 11.Compared to the embodiment of Figure 6, the tray 1 does not have of rib 9 and the collar 6 does not have a rib 11.

La collerette 6 présente en section, entre les jupes extérieure 41 et intérieure 43 du couvercle, une partie 66 en forme de créneau.The collar 6 has in section, between the outer 41 and inner 43 skirts of the cover, a portion 66 in the form of a niche.

Les jupes extérieure 41 et intérieure 43 se situent respectivement de part et d'autre de cette partie 66 lorsque le bac est fermé.The outer skirts 41 and inner skirts 43 are located respectively on the side and other part 66 when the tray is closed.

L'exemple de réalisation de la figure 13 est à rapprocher de celui de la figure 7 et en diffère par le fait que le couvercle comporte à la périphérie de sa paroi supérieure 30 et au-delà de la jupe 31, une nervure 67 sensiblement horizontale lorsque le bac est fermé, venant recouvrir partiellement la paroi de dessus 68 de la partie périphérique 44.The embodiment of Figure 13 is similar to that of Figure 7 and differs from it by the fact that the cover has at the periphery of its upper wall 30 and beyond the skirt 31, a rib 67 substantially horizontal when the tank is closed, partially covering the top wall 68 of the peripheral part 44.

Dans l'exemple de réalisation de la figure 14 la collerette, qui porte la référence 70, s'étend vers l'intérieur, c'est-à-dire vers l'ouverture de la cuve, et se termine par un rebord 71 dirigé vers le haut.In the embodiment of Figure 14 the collar, which bears the reference 70, extends inward, that is to say towards the opening of the tank, and ends in a ledge 71 directed upwards.

Le couvercle comporte, à l'instar de celui de la figure 8, une jupe extérieure 31 et une jupe intérieure 33, la jupe extérieure 31 venant reposer derrière le rebord 71 sur la collerette 70 lorsque le couvercle est fermé et la jupe intérieure 33 s'étendant alors en regard du rebord 71.The cover includes, like that of FIG. 8, an outer skirt 31 and an inner skirt 33, the outer skirt 31 resting behind the rim 71 on the flange 70 when the cover is closed and the inner skirt 33 then extending in look of the ledge 71.

L'écartement entre la jupe 31 et le rebord 71 est par exemple compris entre 2 et 50 mm, étant de préférence inférieur à 15 mm.The distance between the skirt 31 and the rim 71 is for example between 2 and 50 mm, preferably being less than 15 mm.

L'écartement entre la jupe 33 et le rebord 71 est par exemple compris entre 2 mm et 50 mm, étant de préférence inférieur à 15 mm.The distance between the skirt 33 and the flange 71 is for example between 2 mm and 50 mm, preferably being less than 15 mm.

La hauteur du rebord 71 est par exemple comprise entre 0 et 2 cm.The height of the rim 71 is for example between 0 and 2 cm.

La hauteur de la jupe 33, à l'avant du couvercle, est par exemple comprise entre 1 et 8 cm.The height of the skirt 33, at the front of the cover, is for example between 1 and 8 cm.

L'exemple de réalisation de la figure 15 diffère de celui de la figure 2 par l'absence de rebord 7.The embodiment of FIG. 15 differs from that of FIG. 2 by no edge 7.

Dans l'exemple de réalisation de la figure 16, la cuve 2 comporte une collerette identique à celle décrite en référence à la figure 11.In the embodiment of Figure 16, the tank 2 has a flange identical to that described with reference to FIG. 11.

La paroi supérieure du couvercle comporte une partie périphérique 80 ayant en section transversale une forme de créneau, définissant une gorge 81 ouverte vers le bas.The upper wall of the cover has a peripheral part 80 having in cross section a niche shape, defining a groove 81 open downwards.

La largeur de cette gorge est comprise par exemple entre 1 et 10 cm.The width of this groove is for example between 1 and 10 cm.

La gorge 81 est délimitée par des montants verticaux 82 et 83, sensiblement parallèles, ces montants étant réunis par une paroi de dessus 84 horizontale lorsque le bac est fermé.The groove 81 is delimited by vertical uprights 82 and 83, substantially parallel, these uprights being joined by a horizontal top wall 84 when the bin is closed.

Le montant 82, qui constitue également la jupe extérieure du couvercle, vient en appui sur la première marche 60 de la collerette.The upright 82, which also constitutes the outer skirt of the cover, comes resting on the first step 60 of the collar.

Le montant 83, qui constitue en quelque sorte la jupe intérieure du couvercle, vient se positionner en regard de la surface intérieure des parois principales de la cuve.The upright 83, which in a way constitutes the inner skirt of the cover, is positioned opposite the interior surface of the main walls of the tank.

Dans le cas où le couvercle comporte une jupe intérieure, telle que par exemple la jupe 33 de l'exemple de réalisation de la figure 2, la hauteur de cette jupe peut varier selon l'emplacement sur le couvercle.In the case where the cover has an inner skirt, such as for example the skirt 33 of the embodiment of FIG. 2, the height of this skirt can vary depending on the location on the cover.

On peut ainsi, comme illustré sur la figure 17, avoir une jupe intérieure 33 dont la hauteur croít progressivement le long des côtés latéraux du couvercle depuis le côté arrière 4 de ce dernier en direction de son bord avant. It is thus possible, as illustrated in FIG. 17, to have an interior skirt 33 of which the height increases progressively along the lateral sides of the cover from the side rear 4 of the latter towards its front edge.

On évite ainsi, lorsque le bac est ouvert et que le couvercle 3 repose contre la paroi arrière 8 de la cuve 2, de former un décrochement susceptible de s'accrocher sur un organe du mécanisme de levage du véhicule de collecte.This prevents, when the tray is open and the cover 3 rests against the rear wall 8 of the tank 2, to form a step capable of catching on a member of the lifting mechanism of the collection vehicle.

La jupe intérieure 33 peut bien entendu présenter une hauteur constante, comme illustré sur la figure 18.The inner skirt 33 can of course have a constant height, as shown in figure 18.

On peut encore, comme illustré sur la figure 19, réaliser la jupe intérieure 33 avec une hauteur maximale au voisinage des bords avant et arrière du couvercle et décroissant en direction d'une région médiane du couvercle, pour être minimale à ce niveau, cette décroissance s'opérant de préférence de telle manière que le bord inférieur 85 de la jupe intérieure 33 soit parallèle à la paroi supérieure 30 du couvercle.It is also possible, as illustrated in FIG. 19, to produce the inner skirt 33 with a maximum height in the vicinity of the front and rear edges of the cover and decreasing towards a middle region of the cover, to be minimal at this level, this decrease preferably taking place in such a way that the lower edge 85 of the inner skirt 33 is parallel to the upper wall 30 of the cover.

On facilite ainsi le gerbage des couvercles avant leur montage sur les cuves.This makes it easier to stack the covers before they are mounted on the tanks.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits.Of course, the invention is not limited to the exemplary embodiments which have just been described.
