Description

La présente invention concerne un couvercle à joint pour la fermeture d'une boîte à paroi latérale tubulaire ainsi qu'un ensemble comprenant une boîte à paroi latérale tubulaire et un couvercle du type précité.The present invention relates to a seal cover for closing a tubular sidewall box and an assembly comprising a tubular sidewall box and a lid of the aforementioned type.

La présente invention concerne en particulier un couvercle pour la fermeture d'une boîte à paroi latérale tubulaire munie d'une ouverture supérieure et d'une collerette radiale interne disposée sensiblement au niveau de ladite ouverture supérieure, ledit couvercle comprenant, sur sa face dite du dessous, un joint d'étanchéité annulaire élastiquement déformable, apte à venir en appui sur ladite collerette, à l'état fermé de l'ouverture supérieure de la boîte par ledit couvercle.The present invention relates in particular to a lid for closing a tubular side wall box provided with an upper opening and an inner radial collar disposed substantially at said upper opening, said cover comprising, on its so-called face. below, an annular elastically deformable seal, adapted to bear on said flange, in the closed state of the upper opening of the box by said cover.

Un tel couvercle est bien connu à ceux versés dans cet art, comme l'illustre le brevet FR 2 707 258 dans lequel un joint annulaire plat est décrit.Such a lid is well known to those versed in this art, as illustrated by the patent FR 2,707,258 wherein a flat annular seal is described.

En raison de sa conception, un tel joint s'adapte difficilement sur certaines formes complexes de collerette de boîte. En outre, un tel joint, du fait de sa forme plate, présente un effet ressort limité. D'autres couvercles comportant un joint sont connus de US2005/0023772 et US2002/0145939 . Un but de la présente invention est donc de proposer un couvercle du type précité dont la conception du joint permet une adaptation du joint à de multiples formes de collerettes de boîtes, un effet ressort amélioré et une aide au centrage du couvercle sur la boîte.Because of its design, such a seal hardly fits on some complex box flange shapes. In addition, such a seal, because of its flat shape, has a limited spring effect. Other lids having a seal are known from US2005 / 0023772 and US2002 / 0145939 . An object of the present invention is therefore to provide a lid of the aforementioned type, the seal design allows adaptation of the seal to multiple forms of box collars, an improved spring effect and a centering aid of the lid on the box.

À cet effet, l'invention a pour objet un couvercle pour la fermeture d'une boîte à paroi latérale tubulaire munie d'une ouverture supérieure et d'une collerette radiale interne disposée sensiblement au niveau de ladite ouverture supérieure, ledit couvercle comprenant, sur sa face dite du dessous, un joint d'étanchéité annulaire, élastiquement déformable, apte à venir en appui sur ladite collerette, à l'état fermé de l'ouverture supérieure de la boîte par ledit couvercle, à l'état non déformé, ledit joint d'étanchéité affectant la forme générale d'un demi-tore à convexité tournée vers l'extérieur du couvercle, c'est-à-dire vers la boîte, caractérisé en ce que le joint d'étanchéité est fixé au couvercle par l'intermédiaire d'une bague annulaire ou d'un jonc annulaire, ledit jonc délimitant un anneau ouvert. Grâce à la forme convexe du joint, tournée non pas vers le couvercle, mais vers l'extérieur du couvercle, il en résulte une amélioration de l'effet ressort du joint, dans le sens d'un écartement du couvercle de la boîte, ce qui tend, en présence de moyens de fixation du couvercle à la boîte, formés par des moyens de fixation du couvercle venant en prise avec la collerette radiale interne ou un rebord périphérique externe de la boîte, à accroître la force de pression exercée par les moyens de fixation du couvercle sur la boîte, ce qui permet d'augmenter l'efficacité de la fixation.For this purpose, the subject of the invention is a lid for closing a box with a tubular side wall provided with an upper opening and an internal radial flange disposed substantially at said upper opening, said cover comprising, on its so-called underside, an annular seal, elastically deformable, able to bear on said flange, in the closed state of the upper opening of the box by said cover, in the undeformed state, said seal having the general shape of a convex half-torus facing outwardly of the cover, that is to say to the box, characterized in that the seal is attached to the cover by means of an annular ring or an annular ring, said ring defining an open ring. Thanks to the convex shape of the seal, turned not towards the lid, but towards the outside of the lid, this results in an improvement of the spring effect of the seal, in the direction of a spacing of the lid of the box, this which tends, in the presence of means for fixing the lid to the box, formed by fastening means of the cover engaging with the inner radial flange or an outer peripheral rim of the box, to increase the pressure force exerted by the means fixing the lid on the box, which increases the effectiveness of the attachment.

En outre, la forme convexe permet une adaptation du joint à un grand nombre de formes de collerettes radiales internes de boîte.In addition, the convex shape allows the joint to be adapted to a large number of internal radial box collar shapes.

Enfin, la forme convexe du joint aide au centrage du couvercle par rapport à la boîte.Finally, the convex shape of the seal helps to center the cover relative to the box.

De préférence, le demi-tore est creux. Cette réalisation en creux du demi-tore facilite la déformation du joint et l'adaptation du joint à des formes complexes de collerettes.Preferably, the half-torus is hollow. This hollow embodiment of the half-torus facilitates the deformation of the seal and the adaptation of the joint to complex shapes of collars.

De préférence, le demi-tore est ouvert côté face du demi-tore tournée vers le couvercle. À nouveau, cette réalisation facilite la déformation du joint et en particulier, l'écrasement du joint et l'adaptation du joint à des formes complexes de collerettes.Preferably, the half-torus is open on the face of the half-torus turned towards the lid. Again, this embodiment facilitates the deformation of the seal and in particular, the crushing of the seal and the adaptation of the seal to complex shapes of collars.

De préférence, le demi-tore qui comprend un bord circonférentiel interne et un bord circonférentiel externe, est relié au couvercle par une zone de liaison disposée au niveau de l'un de ses bords circonférentiels, et en ce que l'autre bord circonférentiel du demi-tore est libre.Preferably, the half-torus, which comprises an inner circumferential edge and an outer circumferential edge, is connected to the cover by a connecting zone disposed at one of its circumferential edges, and in that the other circumferential edge of the circumferential edge half-torus is free.

Ce bord circonférentiel du demi-tore exempt de zone de liaison au couvercle, est donc un bord libre, c'est-à-dire un bord dont la déformation n'est pas entravée par une éventuelle zone de liaison du bord au couvercle. Il en résulte une meilleure étanchéité et une plus grande adaptabilité aux différents formats de boîte. En outre, l'absence de liaison au niveau du bord circonférentiel empêche le joint de marquer ou de se pincer.This circumferential edge of the half-torus devoid of a zone of connection to the lid, is therefore a free edge, that is to say an edge whose deformation is not hampered by a possible zone of connection of the edge to the lid. This results in better sealing and greater adaptability to different box formats. In addition, the absence of binding at the circumferential edge prevents the seal from marking or pinching.

En variante, le demi-tore qui comprend un bord circonférentiel interne et un bord circonférentiel externe, est relié au couvercle par une zone de liaison disposée au niveau de chacun de ces bords circonférentiels. Toutefois, l'absence de possibilité d'écrasement du joint peut nuire à son efficacité.Alternatively, the half-torus which comprises an inner circumferential edge and an outer circumferential edge, is connected to the cover by a connecting zone disposed at each of these circumferential edges. However, the lack of possibility of crushing the seal can affect its effectiveness.

De préférence, dans le cas d'une bague, la bague est insérée dans un logement annulaire de la face du dessous du fond du couvercle. En particulier, la bague est introduite à force dans ledit logement.Preferably, in the case of a ring, the ring is inserted into an annular housing of the bottom face of the lid bottom. In particular, the ring is forced into said housing.

De préférence, dans le cas d'une bague, la bague et le joint sont surmoulés. De préférence, dans le cas d'un jonc annulaire, ledit jonc est logé à l'intérieur du joint et agit par poussée sur le bord circonférentiel interne du joint pour l'insérer dans une gorge ménagée côté face du dessous du couvercle.Preferably, in the case of a ring, the ring and the seal are overmolded. Preferably, in the case of an annular ring, said ring is housed inside the seal and acts by pushing on the inner circumferential edge of the seal to insert it into a groove on the underside of the lid.

De préférence, le couvercle comprend une poignée et, de préférence, une ouverture centrale prévue pour l'arbre de rotation d'un ensemble mélangeur.Preferably, the cover comprises a handle and, preferably, a central opening provided for the rotation shaft of a mixing assembly.

De préférence, le couvercle comprend des moyens de fixation pour fixer le couvercle à la boîte. Généralement, ces moyens de fixation sont configurés pour permettre, au cours de leur passage d'une position inactive à une position active de fixation à la boîte, de presser le joint du couvercle contre la collerette radiale interne de la boîte.Preferably, the cover comprises fixing means for fixing the lid to the box. Generally, these fixing means are configured to allow, during their passage from an inactive position to an active position of attachment to the box, to press the seal of the cover against the inner radial flange of the box.

Ces pattes peuvent être de simples pattes élastiquement déformables.These tabs can be simple elastically deformable tabs.

De préférence, l'une des pattes mobiles munie d'une partie active de fixation est, pour le déplacement de sa partie active de fixation entre une position rapprochée et une position écartée de la partie active de fixation des autres pattes, montée mobile autour d'un axe ou suivant un plan sensiblement parallèle à un plan circonférentiel du joint annulaire d'étanchéité et le couvercle comprend, pour ladite au moins une patte mobile des moyens de verrouillage du pivotement de ladite patte mobile en position rapprochée de sa partie active de fixation de la partie active de fixation de la ou des autres pattes, ces moyens de verrouillage étant déverrouillables.Preferably, one of the movable tabs provided with an active attachment part is, for the displacement of its active attachment part between a close position and a position separated from the active part for fixing the other tabs, mounted movably around an axis or in a plane substantially parallel to a circumferential plane of the annular seal and the cover comprises, for said at least one movable tab means for locking the pivoting of said movable tab in a position close to its active attachment part the active part fixing the other leg or tabs, these locking means being unlockable.

De préférence, la patte mobile est une patte pivotante et les moyens de verrouillage sont au moins partiellement élastiquement déformables et sont aptes à passer de la position verrouillée à la position déverrouillée ou inversement par déformation élastique combinée avec un déplacement à pivotement de la patte mobile pivotante.Preferably, the movable tab is a pivoting tab and the locking means are at least partially elastically deformable and are able to move from the locked position to the unlocked position or vice versa by elastic deformation combined with a pivotal movement of the pivoting mobile tab .

De préférence, les moyens de verrouillage comprennent des premiers moyens de verrouillage montés solidaires en dépassement de la patte mobile pivotante et des deuxièmes moyens de verrouillage stationnaires, lesdites premiers et deuxièmes moyens de verrouillage étant couplés en position verrouillée et désaccouplés en position déverrouillée.Preferably, the locking means comprise first locking means mounted integral beyond the pivoting mobile tab and the second stationary locking means, said first and second locking means being coupled in the locked position and uncoupled in the unlocked position.

De préférence, ces premiers et deuxièmes moyens de verrouillage sont du type mâle - femelle.Preferably, these first and second locking means are of the male-female type.

De préférence, la partie active de fixation de ladite au moins une patte mobile pivotante est élastiquement déformable.Preferably, the active attachment portion of said at least one pivotable mobile tab is elastically deformable.

De préférence, la ou au moins l'une des pattes mobiles pivotantes est montée mobile à pivotement par l'intermédiaire d'un levier de commande d'entraînement en déplacement à pivotement, et les premiers moyens de verrouillage du pivotement de ladite patte mobile pivotante sont portés par ledit levier de commande et les deuxièmes moyens de verrouillage sont portés par la poignée.Preferably, the or at least one of the pivoting movable lugs is pivotally mounted by means of a pivotally movable drive control lever, and the first pivotal locking means of said pivotable movable lug. are carried by said control lever and the second locking means are carried by the handle.

De préférence, la face dite du dessus du couvercle opposée à la face du dessous forme un bec verseur, ce bec verseur présentant un siège d'un obturateur, ledit siège étant incliné à pente descendante depuis le bord périphérique externe en direction du centre du couvercle, ledit obturateur étant équipé de moyens de rappel en position fermée et d'un levier pivotant de commande d'ouverture de l'obturateur actif à l'encontre desdits moyens de rappel.Preferably, the so-called top face of the lid opposite to the underside forms a spout, this pouring spout having a seat of a shutter, said seat being inclined downwardly from the outer peripheral edge towards the center of the lid said shutter being equipped with return means in the closed position and a pivoting lever for controlling the opening of the active shutter against said return means.

L'inclinaison du siège permet de réduire l'effort de commande à appliquer sur ledit levier de commande d'ouverture de l'obturateur.The inclination of the seat reduces the control effort to be applied to said shutter release control lever.

L'invention a encore pour objet un ensemble du type comprenant d'une part, une boîte à paroi latérale tubulaire munie d'une ouverture supérieure et d'une collerette radiale interne disposée sensiblement au niveau de ladite ouverture supérieure et d'autre part, un couvercle de fermeture de la boîte, ce couvercle dimensionné pour recouvrir l'ouverture supérieure de la boîte, comportant sur sa face dite du dessous un joint d'étanchéité annulaire, élastiquement déformable, apte à venir en appui sur ladite collerette à l'état fermé de l'ouverture supérieure de la boîte par ledit couvercle.The subject of the invention is also an assembly of the type comprising, on the one hand, a tubular sidewall box provided with an upper opening and an inner radial flange disposed substantially at the level of the said upper opening and, on the other hand, a cover for closing the box, this cover designed to cover the upper opening of the box, comprising on its underside said annular seal, elastically deformable, adapted to bear on said collar in the state closed the upper opening of the box by said lid.

Comme mentionné ci-dessus, l'invention a pour objet un couvercle 1 pour la fermeture d'une boîte 30 et l'ensemble formé du couvercle et de la boîte.As mentioned above, the subject of the invention is a lid 1 for closing a box 30 and the assembly formed by the lid and the box.

Comme représenté aux figures, la boîte 30, telle qu'une boîte de peinture, présente une paroi 31 latérale tubulaire munie au voisinage d'une extrémité, d'une collerette 32 radiale interne délimitant une ouverture 34 supérieure sensiblement circulaire.As shown in the figures, the box 30, such as a paint box, has a tubular lateral wall 31 provided near one end with an internal radial flange 32 delimiting an upper opening 34. substantially circular.

Cette paroi 31 latérale tubulaire de la boîte comprend encore un rebord 33 périphérique radial externe disposé également sensiblement au niveau de l'ouverture 34 supérieure et de la collerette 32 radiale interne.This tubular lateral wall 31 of the box further comprises an outer radial peripheral rim 33 also disposed substantially at the level of the upper opening 34 and the inner radial collar 32.

L'ouverture 34 supérieure de la boîte 30 est apte à être fermée par le couvercle 1. Ce couvercle 1 comprend une face du dessous munie d'un joint 4 d'étanchéité annulaire apte à venir en appui sur ladite collerette 32 à l'état fermé de l'ouverture 34 supérieure de la boîte 30 par ledit couvercle.The upper opening 34 of the box 30 is able to be closed by the lid 1. This lid 1 comprises a bottom face provided with an annular sealing gasket 4 adapted to bear on said flange 32 in the state closed the upper opening 34 of the box 30 by said lid.

A l'état non déformé, ledit joint 4 d'étanchéité affecte la forme générale d'un demi-tore à convexité tournée vers l'extérieur du couvercle 1.In the undeformed state, said sealing gasket 4 has the general shape of a convex half-torus turned towards the outside of the lid 1.

La surface 5 convexe du joint 4 est donc tournée vers l'extérieur du couvercle, de sorte que la face 6 du joint 4 en regard de la face du dessous du couvercle 1 correspond à la face du joint passant par le plan de coupe du demi-tore.The convex surface of the gasket 4 is thus turned towards the outside of the lid, so that the face 6 of the gasket 4 facing the underside of the lid 1 corresponds to the face of the gasket passing through the cutting plane of the half -tore.

Dans les exemples représentés, le demi-tore est creux et ouvert, côté face 6 du demi-tore tournée vers le couvercle 1.In the examples shown, the half-torus is hollow and open, face-side 6 of the half-torus turned towards the cover 1.

Bien évidemment, en variante, le demi-tore aurait pu être réalisé plein mais cette solution n'est pas préférée.Of course, alternatively, the half-torus could have been made full but this solution is not preferred.

Ce joint 4 d'étanchéité présente un bord 7 circonférentiel interne, un bord 8 circonférentiel externe et une zone 9 de liaison au couvercle 1 disposée au niveau de l'un des bords circonférentiels.This seal 4 has an inner circumferential edge 7, an outer circumferential edge 8 and a zone 9 of connection to the lid 1 disposed at one of the circumferential edges.

Dans l'exemple représenté, la zone 9 de liaison est disposée au niveau du bord 7 circonférentiel interne du joint 4 d'étanchéité et le bord 8 circonférentiel externe est libre.In the example shown, the connecting zone 9 is disposed at the inner circumferential edge 7 of the seal 4 and the outer circumferential edge 8 is free.

Bien évidemment, une solution dans laquelle la zone 9 de liaison au couvercle est disposée au niveau du bord circonférentiel externe du joint alors que le bord circonférentiel interne du joint est libre est également envisageable.Of course, a solution in which the zone 9 of connection to the lid is disposed at the outer circumferential edge of the seal while the inner circumferential edge of the seal is free is also possible.

De même, une solution dans laquelle une zone de liaison au couvercle est disposée au niveau de chacun des bords circonférentiels du joint est également envisageable, mais non préférée.Likewise, a solution in which a lid-engaging zone is disposed at each of the circumferential edges of the gasket is also conceivable, but not preferred.

Dans les exemples représentés aux figures 1 à 10, le joint 4 d'étanchéité est fixé au couvercle par l'intermédiaire d'une bague 10 annulaire. Cette bague annulaire est solidarisée au bord circonférentiel interne du joint et est logée par introduction à force dans un logement annulaire ménagé dans la face du dessous du couvercle. Idéalement, la bague 10 annulaire est surmoulée sur le joint, ce qui évite tout risque d'erreur au montage.In the examples shown in Figures 1 to 10 , the seal 4 is attached to the lid by means of an annular ring. This annular ring is secured to the inner circumferential edge of the seal and is housed by forced insertion into an annular recess in the underside of the cover. Ideally, the annular ring 10 is overmolded on the seal, which avoids any risk of error assembly.

Dans l'exemple représenté aux figures 13 et 14, le joint 4 d'étanchéité est fixé au couvercle par l'intermédiaire d'un jonc 10' annulaire élastiquement déformable délimitant un anneau ouvert. Les extrémités libres du jonc sont recourbées pour former des surfaces d'appui des doigts d'un opérateur pour permettre, par réduction du diamètre de l'anneau formé par le jonc, lors d'un rapprochement des extrémités libres, l'insertion du jonc à l'intérieur du joint. Le relâchement du jonc entraîne une augmentation du diamètre de l'anneau par écartement des extrémités libres du jonc. Grâce à cette augmentation du diamètre, le jonc génère sur le bord circonférentiel interne du joint une poussée qui assure l'introduction dudit bord de joint dans une gorge annulaire ménagée côté face du dessous du couvercle.In the example shown in figures 13 and 14 , the seal 4 is attached to the lid by means of an annular ring 10 'elastically deformable delimiting an open ring. The free ends of the ring are bent to form bearing surfaces of the fingers of an operator to allow, by reducing the diameter of the ring formed by the ring, during a coming together of the free ends, the insertion of the ring inside the joint. The loosening of the ring causes an increase in the diameter of the ring by spacing the free ends of the ring. With this increase in diameter, the rod generates on the inner circumferential edge of the seal a thrust which ensures the introduction of said seal edge in an annular groove formed on the underside of the lid.

Le couvercle comprend encore des moyens 14 de fixation pour fixer le couvercle 1 à la boîte 30.The cover further comprises means 14 for fixing the lid 1 to the box 30.

Dans l'exemple représenté à la figure 1B, les moyens 14 de fixation comprennent deux leviers 141 à came, rotatifs, chargés par ressort 142, et déplaçables axialement par coopération de surfaces 143 dites complémentaires portées respectivement par le couvercle 1 et le levier 141 à came lors de l'entraînement en rotation des leviers 141 à came pour passer d'une position fermée du couvercle 1 dans laquelle la came prend appui sous la collerette 32 de la boîte 30 à une position ouverte dans laquelle la came est dégagée de ladite collerette 32, le déplacement axial du levier 141 à came dans le sens d'un éloignement du couvercle 1 de la came provoquant une compression du ressort 142.In the example shown in Figure 1B , the fastening means 14 comprise two levers 141 to cam, rotating, loaded by spring 142, and axially displaceable by cooperation of complementary surfaces 143 respectively carried by the cover 1 and the lever 141 to cam during the driving in rotation of levers 141 to cam to move from a closed position of the cover 1 in which the cam bears under the flange 32 of the box 30 to an open position in which the cam is disengaged from said flange 32, the axial displacement of the lever 141 to cam in the direction of a distance from the cover 1 of the cam causing compression of the spring 142.

Lorsque la boîte est munie, en outre, d'un rebord 33 périphérique radial externe disposé sensiblement au niveau de ladite ouverture 34 supérieure, les moyens 14 de fixation peuvent comprendre à la place de leviers à came au moins deux pattes 144 s'étendant autour dudit joint 4 et au moins partiellement en saillie de la face du dessous 2 du couvercle 1.When the box is provided, furthermore, with an external radial peripheral rim 33 disposed substantially at the level of said upper opening 34, the fixing means 14 may comprise instead of cam levers at least two tabs 144 extending around said gasket 4 and at least partially projecting from the underside 2 of the lid 1.

Au moins l'une des pattes 144 peut être montée mobile dans le sens d'un rapprochement et d'un écartement de la ou des autres pattes 144. Chaque ou au moins deux des pattes 144 présente une partie 145 active de fixation formée par une partie de la patte 144 en saillie en direction du centre du couvercle. Cette partie 145 active est apte à se positionner sous ledit rebord 33 périphérique radial externe de la boîte 30 en position rapprochée desdites pattes 144 correspondant à la position active de fermeture du couvercle 1.At least one of the tabs 144 can be mounted movably in the direction of a bringing together and a spacing of the other tabs 144. Each or at least two of the tabs 144 has an active part 145 fixing formed by a part of the tab 144 projecting towards the center of the lid. This active part 145 is able to be positioned under said outer peripheral peripheral rim 33 of the box 30 in a position close to said tabs 144 corresponding to the active closing position of the lid 1.

Dans un mode de réalisation non représenté, ces pattes peuvent être réalisées sous forme de simples pattes élastiquement déformables qui, lorsque le couvercle est positionné au-dessus de l'ouverture supérieure de la boîte et déplacé en direction de ladite ouverture, s'écartent au passage du rebord 33 périphérique externe de la boîte avant de se resserrer sous ledit rebord et venir en prise avec ce dernier.In an embodiment not shown, these tabs can be made in the form of simple elastically deformable tabs which, when the cover is positioned above the upper opening of the box and moved towards said opening, deviate passage of the rim 33 external device of the box before tightening under said rim and come into engagement therewith.

Ces pattes peuvent encore être réalisées sous forme de trois pattes disposées autour du joint annulaire et s'étendant en saillie de la face du dessous du couvercle. Ces trois pattes sont disposées espacées les unes des autres sur la circonférence du couvercle.These tabs can also be made in the form of three tabs arranged around the annular seal and extending projecting from the underside of the cover. These three tabs are arranged spaced apart from each other on the circumference of the lid.

La face 2 du dessous du couvercle est munie sur au moins une partie de son pourtour d'une bordure annulaire formant un bord tombé de la face du dessous. Cette bordure annulaire recouvre au moins une partie de la paroi 31 latérale tubulaire de la boîte lorsque le couvercle est positionné sur l'ouverture 34 supérieure de la boîte 30.The underside 2 of the lid is provided on at least a portion of its periphery with an annular rim forming a fallen edge of the underside. This annular border covers at least a portion of the tubular lateral wall 31 of the box when the lid is positioned on the upper opening 34 of the box 30.

Deux des pattes sont des pattes rigides réalisées d'une seule pièce avec ladite bordure annulaire.Two of the tabs are rigid tabs made in one piece with said annular rim.

Chacune des pattes 144 présente une partie active de fixation formée par une partie de la patte en saillie en direction du centre du couvercle. La partie 145 active de fixation de chacune des pattes rigides est formée par un cran ou dent ménagé sur la surface de la patte tournée vers le centre du couvercle.Each of the tabs 144 has an active attachment portion formed by a portion of the protruding tab toward the center of the lid. The active portion 145 fixing each of the rigid tabs is formed by a notch or tooth formed on the surface of the tab facing the center of the lid.

La troisième patte peut être une patte mobile déplaçable entre une position rapprochée et une position écartée de sa partie 145 active de fixation, de la partie active de fixation des autres pattes.The third leg may be a movable tab movable between a close position and a position away from its active attachment portion 145, the active part of fixing the other legs.

Ces parties actives de fixation sont aptes à se positionner sous le rebord 33 périphérique radial externe de la boîte en position rapprochée correspondant à la position active de fermeture du couvercle, lorsque le couvercle 1 est positionné sur l'ouverture 34 supérieure de la boîte.These active attachment parts are able to be positioned under the external peripheral peripheral rim 33 of the box in the close position corresponding to the active closing position of the lid, when the lid 1 is positioned on the upper opening 34 of the box.

La troisième patte est, pour le déplacement de sa partie active de fixation entre une position rapprochée et une position écartée de la partie active de fixation des autres pattes montée mobile à pivotement autour d'un axe (XX') sensiblement parallèle à un plan circonférentiel du joint 4 annulaire d'étanchéité.The third tab is, for the displacement of its active part of fixing between a close position and a position separated from the active part of fixing of the other legs mounted to pivotably about an axis (XX ') substantially parallel to a circumferential plane seal 4 annular sealing.

Comme l'illustrent les figures 11 à 12, la troisième patte peut être pour le déplacement de sa partie active de fixation entre une position rapprochée et une position écartée de la partie active de fixation des autres pattes, montée mobile à coulissement suivant un plan sensiblement parallèle au plan circonférentiel du joint 4 annulaire d'étanchéité.As illustrated by Figures 11 to 12 , the third tab may be for the displacement of its active attachment part between a close position and a position spaced from the active part for fixing the other tabs, mounted to slide in a plane substantially parallel to the circumferential plane of the annular seal 4 of sealing.

Dans ce cas, ladite patte est chargée par ressort, ledit ressort tendant à rappeler la patte coulissante en position rapprochée de sa partie active de fixation de la partie active de fixation de la ou des autres pattes.In this case, said tab is loaded by spring, said spring tending to recall the sliding tab in the close position of its active portion for fixing the active part of fixing the other tab or tabs.

Le couvercle comprend, pour ladite patte mobile pivotante, des moyens 19 de verrouillage du pivotement de ladite patte mobile pivotante en position rapprochée de sa partie active de fixation de la partie active de fixation des autres pattes, ces moyens 19 de verrouillage étant déverrouillables.The cover comprises, for said pivotable mobile tab, means 19 for locking the pivoting of said pivoting mobile tab in position close to its active part fixing the active attachment part of the other legs, these locking means 19 being unlockable.

Dans l'exemple représenté, la patte mobile pivotante affecte, entre sa liaison pivot et son extrémité libre, la forme d'un V dont la branche du V qui porte l'extrémité libre de la patte forme la partie active de fixation de la patte.In the example shown, the pivoting mobile tab affects, between its pivot connection and its free end, the shape of a V whose branch of the V which carries the free end of the tab forms the active part of fixing the tab .

Dans l'exemple représenté, cette partie active de fixation de la patte mobile pivotante est élastiquement déformable. La déformation élastique s'opère par rapprochement des branches du V.In the example shown, this active part for fixing the pivoting mobile tab is elastically deformable. The elastic deformation takes place by bringing the branches of the V.

L'autre branche du V est munie de deux portions d'axe s'insérant chacune dans un palier d'axe ménagé dans le reste du couvercle. Palier d'axe et portion d'axe forment les éléments de la liaison pivot permettant un montage à pivotement de la patte 144 mobile pivotante.The other leg of the V is provided with two axis portions each inserted in a bearing axis formed in the rest of the lid. Axle bearing and axle portion form the elements of the pivot connection allowing pivotal mounting of the pivoting mobile tab 144.

Pour la manoeuvre de la patte mobile pivotante, le couvercle comprend un levier 20 de commande d'entraînement en déplacement à pivotement de la patte. Ce levier 20 de commande est ici réalisé d'une seule pièce avec la patte et forme un prolongement de la branche du V de la patte équipée d'une liaison pivot.For the operation of the pivoting mobile lug, the cover comprises a drive control lever 20 in pivotal movement of the tab. This control lever 20 is here made in one piece with the tab and forms an extension of the leg V of the leg equipped with a pivot connection.

Les moyens 19 de verrouillage du pivotement de la patte mobile pivotante en position rapprochée de sa partie active de fixation de la partie active de fixation des autres pattes comprennent des premiers moyens 191 de verrouillage montés solidaires en déplacement de la patte mobile pivotante et des deuxièmes moyens 192 de verrouillage stationnaires, ces premiers et deuxièmes moyens de verrouillage étant couplés en position verrouillée et désaccouplés en position déverrouillée.The means 19 for locking the pivoting mobile lug in position close to its active attachment part of the active attachment part of the other lugs comprise first locking means 19 integral with the pivoting mobile lug and the second means Stationary locking means, these first and second locking means being coupled in the locked position and uncoupled in the unlocked position.

Ces premiers moyens 191 de verrouillage sont formés par un cran ou ergot porté par le levier 20 de commande et les deuxièmes moyens 192 de verrouillage sont formés par une lumière ménagée dans la poignée, en particulier dans la branche verticale de la poignée.These first locking means 191 are formed by a notch or lug carried by the control lever 20 and the second locking means 192 are formed by a slot in the handle, in particular in the vertical leg of the handle.

À l'état couplé correspondant à la position verrouillée, le cran s'insère dans la lumière.In the coupled state corresponding to the locked position, the notch fits into the light.

Pour le déverrouillage, le levier étant élastiquement déformable, il suffit d'appuyer sur le cran qui génère une déformation du levier, ce qui permet une sortie du cran de la lumière. Une fois déverrouillée, la patte mobile peut être entraînée en déplacement à pivotement dans le sens d'un écartement de sa partie active de fixation des parties actives de fixation des autres pattes.For unlocking, the lever being elastically deformable, simply press the notch which generates a deformation of the lever, which allows an output of the notch of the light. Once unlocked, the movable lug may be driven in pivotal displacement in the direction of a spacing of its active portion for fixing the active parts for fixing the other tabs.

Pour le verrouillage, on procède de manière inverse : la patte mobile pivotante est commandée en déplacement à pivotement dans le sens d'un rapprochement de sa partie active de fixation des autres parties actives de fixation ou du centre du couvercle, jusqu'à une position où le cran porté par le levier 20 de commande d'entraînement à déplacement de la patte vient par encliquetage se loger dans la lumière ménagée dans la poignée 12.For the locking, the procedure is the reverse: the pivoting mobile tab is controlled in pivoting movement in the direction of approximation of its active attachment part of the other active attachment parts or the center of the cover, to a position wherein the notch carried by the lever for driving movement of the tab comes snap fit into the lumen formed in the handle 12.

Dans le cas d'une patte mobile coulissante, les moyens 19' de verrouillage du coulissement de la patte sont formés par une vis à molette vissable/dévissable dans le couvercle, l'extrémité libre de la vis venant en appui sur la patte en position verrouillée.In the case of a movable sliding lug, the means 19 'for locking the sliding of the lug are formed by a screw with a screw wheel that can be screwed / unscrewed into the lid, the free end of the screw coming to bear on the lug in position locked.

Dans les exemples représentés, le couvercle comprend encore une poignée 12. Cette poignée radiale externe 12 affecte la forme d'un L inversé.In the examples shown, the lid further comprises a handle 12. This external radial handle 12 has the shape of an inverted L.

On note que dans l'exemple représenté, la branche horizontale du L inversé de la poignée est ici évidée pour permettre le logement du levier 20 de commande d'entraînement en déplacement à pivotement de la patte mobile pivotante et son passage d'une position à une autre.Note that in the example shown, the horizontal arm of the inverted L of the handle is recessed here to allow the housing of the drive control lever 20 to move in pivotal movement of the movable pivoting lug and its passage from a position to another.

Dans les exemples représentés, le couvercle présente encore une face 3 du dessus opposée à la face 2 du dessous qui forme un bec 15 verseur. Ce bec 15 verseur présente un siège 151 d'un obturateur 16. Ce siège 151 est formé par la surface du dessus ouverte du bec verseur.In the examples shown, the lid also has a face 3 of the top opposite to the underside 2 which forms a spout 15. This spout 15 has a seat 151 with a shutter 16. This seat 151 is formed by the open top surface of the spout.

Dans les exemples représentés, le siège 151 du bec 15 verseur est incliné à pente descendante depuis la périphérie en direction du centre du couvercle 1. L'obturateur 16 est un obturateur coulissant équipé de moyens 17 de rappel en position fermée et d'un levier 18 pivotant de commande d'ouverture actif à l'encontre desdits moyens 17 de rappel. Le levier 18 pivotant de commande d'ouverture de l'obturateur 16 surmonte la patte mobile pivotante.In the examples shown, the seat 151 of the spout 15 is inclined to downward slope from the periphery towards the center of the lid 1. The shutter 16 is a sliding shutter equipped with means 17 for return in the closed position and a lever 18 pivoting opening control active against said means 17 recall. The shutter opening control pivot lever 18 overcomes the pivoting mobile tab.

L'obturateur 16 est ici formé par une simple plaque et les moyens 17 de rappel sont réalisés sous forme d'un ressort en épingle à cheveux dont la coopération avec l'obturateur est déjà connue de l'état de la technique et ne sera donc pas décrite en détail.The shutter 16 is here formed by a simple plate and the return means 17 are made in the form of a hairpin spring whose cooperation with the shutter is already known from the state of the art and therefore will be not described in detail.

Le levier 18 pivotant de commande d'ouverture de l'obturateur 16 qui surmonte la patte mobile pivotante ou coulissante est monté mobile à pivotement autour d'un axe parallèle à l'axe (XX') de pivotement ou au plan de déplacement de la patte mobile qu'il surmonte.The shutter opening control pivoting lever 18 which overcomes the pivoting or sliding mobile tab is pivotally mounted about an axis parallel to the pivot axis (XX ') or to the plane of movement of the movable paw he overcomes.

Ce levier 18 pivotant de commande d'ouverture de l'obturateur 16 forme en outre, si nécessaire, lors de la commande d'ouverture de l'obturateur, un organe de commande de verrouillage des moyens 19 de verrouillage du pivotement de la patte mobile pivotante surmontée par ledit levier 18 lorsque ladite patte mobile est une patte pivotante.This pivoting shutter opening control lever 18 furthermore forms, if necessary, during the shutter opening control, a locking control member of the locking means 19 for pivoting the movable tab. pivoting member surmounted by said lever 18 when said movable tab is a pivoting lug.

En effet, si le levier 20 de commande d'entraînement en déplacement à pivotement de la patte mobile n'a pas d'ores et déjà été actionné pour l'amenée de la patte mobile en position verrouillée, il peut être actionné par le levier 18 pivotant de commande d'ouverture de l'obturateur 16 qui le surmonte.Indeed, if the lever 20 for driving control in pivoting movement of the movable tab has not already been actuated for the supply of the movable tab in the locked position, it can be actuated by the lever 18 shutter opening control pivot 16 which overcomes it.

Ainsi, le passage de l'obturateur de la position fermée à la position ouverte peut permettre en parallèle le passage de la patte de la position déverrouillée à la position verrouillée.Thus, the passage of the shutter from the closed position to the open position can allow in parallel the passage of the tab from the unlocked position to the locked position.

Lorsque le couvercle 1 est un couvercle agitateur, le couvercle 1 comprend encore une ouverture 13 centrale prévue pour l'arbre de rotation d'un ensemble mélangeur.When the lid 1 is an agitator lid, the lid 1 further comprises a central opening 13 provided for the rotation shaft of a mixer assembly.

En pratique, la fermeture d'une boîte à l'aide d'un couvercle tel que décrit ci-dessus peut s'opérer comme suit : le couvercle 1 est positionné avec sa face du dessous en regard de l'ouverture supérieure de la boîte. La patte mobile pivotante du couvercle est déverrouillée et sa partie active de fixation est écartée des parties actives de fixation des autres pattes de fixation ou du centre du couvercle.In practice, the closure of a box with a lid as described above can be done as follows: the lid 1 is positioned with its underside facing the upper opening of the box . The pivoting mobile lug of the lid is unlocked and its active attachment part is moved away from the active parts of attachment of the other fixing lugs or the center of the lid.

Les parties actives de fixation des pattes rigides, c'est-à-dire non pivotantes sont positionnées sous le rebord 33 périphérique radial externe de la boîte. La patte mobile pivotante est, par l'intermédiaire de son levier 20 de commande qui est manoeuvré par la main de l'opérateur qui tient la poignée 12 de saisie du couvercle, entraînée en déplacement à pivotement jusqu'à une position dans laquelle la partie active de fixation de la patte mobile pivotante est disposée par appui sur la face du dessous du rebord 33 périphérique radial externe, c'est-à-dire la face du rebord 33 périphérique radial externe tournée vers le fond de la boîte opposé à la face d'extrémité de la boîte qui porte l'ouverture supérieure.The active parts for fixing the rigid tabs, that is to say non-pivoting are positioned under the outer peripheral rim 33 of the box. The pivoting mobile tab is, via its control lever 20 which is operated by the hand of the operator who holds the grip 12 of the lid, driven in pivoting motion to a position in which the part active attachment of the pivoting mobile lug is disposed by pressing on the underside of the rim 33 outer radial peripheral, that is to say the face of the rim 33 external radial peripheral turned towards the bottom of the box opposite the face end of the box that carries the top opening.

Dans cette position de la patte, le cran 191 du levier 20 de commande d'entraînement en pivotement de la patte 144 mobile s'insère dans la lumière 192 de la poignée et le verrouillage de la patte s'opère de sorte que tout déplacement à pivotement de la patte 144 suivant une direction opposée est empêché.In this position of the tab, the notch 191 of the pivoting drive control lever 20 of the movable tab 144 is inserted into the light 192 of the handle and the locking of the tab operates so that any movement to pivoting of tab 144 in an opposite direction is prevented.

La fixation du couvercle 1 à la boîte est achevée.The fixing of the cover 1 to the box is completed.

En variante, il peut être prévu d'amener d'abord la partie active de fixation de la patte mobile pivotante sous le rebord périphérique de la boîte avant d'exercer une poussée sur le couvercle et de pousser le couvercle pour amener les parties actives de fixation des pattes 144 rigides sous le rebord périphérique de la boîte. L'actionnement de la patte mobile et son verrouillage s'opèrent ensuite comme décrit ci-dessus.Alternatively, it can be provided to first bring the active part fixing the pivoting mobile tab under the peripheral rim of the box before exerting a thrust on the lid and push the lid to bring the active parts of the fixing rigid tabs 144 under the peripheral rim of the box. The actuation of the mobile tab and its locking then operate as described above.

Lorsque la patte mobile est une patte coulissante comme illustré à la figure 11, l'opérateur exerce une traction sur la patte 144 à l'encontre du ressort pour l'écarter des autres pattes puis relâcher ladite patte dont la partie active de fixation vient se positionner sous le rebord périphérique radial externe de la boîte en position d'appui contre la face externe de la paroi périphérique de la boîte. Il est ensuite procédé au verrouillage en position de ladite patte.When the movable tab is a sliding tab as shown in FIG. figure 11 , the operator exerts traction on the tab 144 against the spring to move it away from the other legs and release said tab whose active attachment portion is positioned under the outer radial peripheral rim of the box in the support position against the outer face of the peripheral wall of the box. It is then locked in position of said tab.

L'obturateur du bec verseur peut être actionné dans le sens d'une ouverture à l'aide du levier 18 pivotant. Le relâchement du levier 18 entraîne automatiquement le retour de l'obturateur en position fermée, à l'aide des moyens 17 de rappel.The shutter of the spout can be actuated in the direction of an opening with the lever 18 pivoting. Releasing the lever 18 automatically causes the shutter to return to the closed position, using the return means 17.

Pour désolidariser le couvercle de la boîte, il suffit d'exercer une pression sur le cran 191 dans le sens d'une extraction du cran 191 de la lumière 192, puis d'entraîner en déplacement à pivotement la patte 143 dans le sens d'un écartement de la partie active de fixation de la patte des parties actives de fixation des autres pattes ou du centre du couvercle.To separate the lid of the box, it is sufficient to exert pressure on the notch 191 in the direction of an extraction of the notch 191 of the light 192, and then to cause the tab 143 to pivotally move in the direction of rotation. a separation of the active part for fixing the tab of the active parts for fixing the other tabs or the center of the cover.

Pour l'actionnement de la patte mobile pivotante dans le sens d'un rapprochement de sa partie active de fixation des parties actives de fixation des autres pattes, il est possible d'agir sur le levier 18 de manoeuvre de l'obturateur, ce levier 18 venant, au cours de son pivotement, en appui sur le levier 20 de manoeuvre et l'entraînant en déplacement jusqu'à une position de fin de course dans laquelle il est verrouillé.For actuation of the movable pivoting lug in the direction of approximation of its active attachment part of the active attachment parts of the other legs, it is possible to act on the lever 18 for operating the shutter, this lever 18 coming, during its pivoting, bearing on the operating lever 20 and driving it to an end position position in which it is locked.

On note que les manoeuvres du levier 18 de commande d'ouverture de l'obturateur et du levier 20 de commande de l'entraînement en déplacement à pivotement de la patte 144 sont effectuées par la main de l'opérateur qui tient la poignée 12. C'est le pouce de cette main, qui permet d'agir sur ces deux leviers.It will be noted that the operations of the lever 18 for controlling the opening of the shutter and the lever 20 for controlling the drive in pivotal displacement of the tab 144 are carried out by the hand of the operator holding the handle 12. It is the thumb of this hand, which allows to act on these two levers.

Ainsi, en dépit de la présence de deux leviers, une seule main suffit pour actionner ces deux leviers.Thus, despite the presence of two levers, one hand is sufficient to operate these two levers.
