Description

On connaît de longue date des pots, notamment des pots contenant de la peinture, qui sont munis de couvercles amovibles comportant un agitateur.Jars have been known for a long time, in particular pots containing paint, which are provided with removable lids comprising an agitator.

Les couvercles amovibles sont, le plus souvent, fixés aux pots par des cames pouvant être actionnées depuis l'extérieur du couvercle au moyen d'un levier.The removable lids are most often fixed to the pots by cams which can be actuated from the outside of the lid by means of a lever.

Les cames sont amenées à pivoter à l'intérieur du pot pour être appliquées de façon de plus en plus ferme contre une portée d'appui formée par le dessous d'une couronne bordant le dessus du pot.The cams are made to pivot inside the pot to be applied more and more firmly against a bearing surface formed by the underside of a crown bordering the top of the pot.

Il est apparu que certains produits, notamment des peintures à solvant aqueux, provoquent des corrosions des pots métalliques couramment employés dans la technique. Pour pallier cet inconvénient, les fabricants de pots procèdent habituellement au revêtement de la paroi interne du pot et de la couronne qui le surmonte au moyen d'un vernis ou autre produit de protection analogue.It has been found that certain products, in particular paints with an aqueous solvent, cause corrosion of the metal pots commonly used in the art. To overcome this drawback, pot manufacturers usually coat the inner wall of the pot and the crown which surmounts it with a varnish or other similar protective product.

Ce mode de protection donne satisfaction mais il est apparu que les couvercles comportant une fermeture à came détériorent la portée d'appui de la couronne des pots par abrasion du produit de protection puisque les cames frottent fortement contre la portée au moment de la fermeture et il résulte de cet effet que les corrosions se produisent de nouveau.This mode of protection is satisfactory, but it has been found that the covers comprising a cam closure deteriorate the bearing surface of the crown of the pots by abrasion of the protection product since the cams rub strongly against the surface at the time of closing and it As a result of this effect, corrosions occur again.

La présente invention apporte une solution au problème exposé ci-dessus.The present invention provides a solution to the problem set out above.

Conformément à l'invention, le couvercle à cames pour la fermeture d'un pot de peinture et applications analogues, dans lequel le couvercle est muni, sur son dessous, d'un joint d'étanchéité serré sur un rebord d'une couronne bordant la partie supérieure du pot au moyen de cames pivotantes disposées en dessous dudit couvercle et commandées par des leviers placés au-dessus du couvercle, au moins ladite couronne étant revêtue intérieurement d'une matière sensible à la friction, est caractérisé en ce que chaque came est reliée à chaque levier de commande par un axe, en ce qu'un ressort est relié audit axe pour tendre à le faire coulisser dans le sens pour lequel la came est serrée contre la portée de la couronne en faisant que le joint du couvercle soit pressé contre un rebord de ladite couronne, en ce que des moyens sont prévus pour maintenir chaque came à distance de la portée de la couronne pour toutes les positions desdites cames à l'exception d'une position pour laquelle lesdites cames s'étendent vers l'extérieur du couvercle, de sorte que lesdites cames n'appliquent, au revêtement sensible à la friction, qu'une force de compression lorsqu'elles occupent la position de fermeture du couvercle.According to the invention, the cam cover for closing a paint can and similar applications, in which the cover is provided, on its underside, with a tight seal on a rim of a bordering crown the upper part of the pot by means of pivoting cams arranged below said cover and controlled by levers placed above the cover, at least said crown being coated internally with a material sensitive to friction, is characterized in that each cam is connected to each control lever by an axis, in that a spring is connected to said axis in order to tend to make it slide in the direction for which the cam is tightened against the bearing surface of the crown while making that the seal of the cover is pressed against a flange of said crown, in that means are provided for keeping each cam at a distance from the bearing of the crown for all the positions of said cams except for a position for which said cams extend towards the outside of the cover, so that said cams apply, to the friction-sensitive coating, only a compressive force when they occupy the closed position of the cover.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, aux dessins annexés.Embodiments of the subject of the invention are shown, by way of nonlimiting examples, in the accompanying drawings.

La fig. 1 est une coupe-élévation en partie schématique du couvercle à cames mis en place sur un pot de peinture.Fig. 1 is a partly schematic elevation section of the cam cover placed on a paint can.

La fig. 2 est une perspective vue de trois quarts par en dessous du couvercle schématisé à la fig. 1.Fig. 2 is a perspective view from three quarters below the cover shown diagrammatically in FIG. 1.

La fig. 3 est une élévation partielle illustrant une des cames de fermeture dans la position permettant le retrait du couvercle.Fig. 3 is a partial elevation illustrating one of the closing cams in the position allowing the cover to be removed.

La fig. 4 est un plan partiel vu sensiblement suivant la ligne IV-IV de la fig. 3.Fig. 4 is a partial plan seen substantially along line IV-IV of FIG. 3.

La fig. 5 est une élévation analogue à la fig. 3 montrant une came dans la position qu'elle occupe lors de la fermeture du couvercle.Fig. 5 is an elevation similar to FIG. 3 showing a cam in the position it occupies when the cover is closed.

La fig. 6 est un plan partiel vu suivant la ligne VI-VI de la fig. 5.Fig. 6 is a partial plan seen along line VI-VI of FIG. 5.

La fig. 7 est une coupe-élévation vue suivant la ligne VII-VII de la fig. 3.Fig. 7 is a sectional elevation seen along line VII-VII of FIG. 3.

La fig. 1 illustre un pot 1 destiné à contenir un produit liquide ou pâteux, par exemple une peinture. Le pot 1 comporte une paroi latérale 2 de révolution, le plus souvent cylindrique, qui est fabriquée en métal ou éventuellement en matière synthétique.Fig. 1 illustrates a pot 1 intended to contain a liquid or pasty product, for example a paint. The pot 1 has a side wall 2 of revolution, most often cylindrical, which is made of metal or possibly of synthetic material.

La paroi latérale 2 du pot supporte à son sommet une couronne 3 qui est, par exemple, sertie comme montré en 4. La couronne 3 délimite une portée 5 dirigée vers la base du pot et un rebord supérieur 6 sur lequel prend appui un joint plat 7 dont est muni un couvercle 8.The side wall 2 of the pot supports at its top a crown 3 which is, for example, crimped as shown in 4. The crown 3 defines a bearing 5 directed towards the base of the pot and an upper rim 6 on which a flat seal rests 7 which is provided with a cover 8.

La couronne 3 est réalisée en métal, par exemple en fer blanc.The crown 3 is made of metal, for example of tinplate.

Au moins la face de la couronne 3 qui est tournée vers l'intérieur du pot est revêtue d'un vernis destiné à protéger le métal des risques de corrosion pouvant être provoqués par le produit contenu dans le pot 1 dont la paroi interne est également revêtue d'un vernis lorsque cette paroi est elle-même fabriquée en métal, notamment en fer blanc.At least the face of the crown 3 which faces the inside of the pot is coated with a varnish intended to protect the metal from the risks of corrosion which can be caused by the product contained in the pot 1, the internal wall of which is also coated with a varnish when this wall is itself made of metal, in particular of tinplate.

Pour que le couvercle soit posé convenablement sur le rebord 6, il est avantageusement muni de plots latéraux 9 saillant vers le bas et destinés à s'étendre latéralement par rapport au bord serti 4 du couvercle.So that the cover is properly placed on the rim 6, it is advantageously provided with lateral studs 9 projecting downwards and intended to extend laterally relative to the crimped edge 4 of the cover.

De façon connue dans la technique, le couvercle 8 est muni d'un agitateur 10, par exemple en forme d'hélice, qui est monté sur un arbre 11 entraîné par un accouplement 12, lui-même mû par un organe moteur, non représenté.As is known in the art, the cover 8 is provided with an agitator 10, for example in the form of a propeller, which is mounted on a shaft 11 driven by a coupling 12, itself driven by a motor member, not shown. .

Le couvercle 8 comporte sur son dessus un bec verseur obturé par un papillon 14 pouvant être déplacé par une gâchette 15.The cover 8 has on its top a pouring spout closed by a butterfly 14 which can be moved by a trigger 15.

Pour assurer le verrouillage du couvercle 8 sur le pot 1, le couvercle est muni sur son dessous de cames 16 pouvant être manoeuvrées chacune à partir d'un levier 17.To ensure the locking of the cover 8 on the pot 1, the cover is provided on its underside with cams 16 which can each be operated from a lever 17.

Le couvercle 8 est muni d'au moins deux cames 16, ce nombre pouvant croître en fonction du diamètre du pot et, par conséquent, du couvercle.The cover 8 is provided with at least two cams 16, this number possibly increasing as a function of the diameter of the pot and, consequently, of the cover.

La fig. 7 montre que le couvercle 8 présente, en dessous du joint 7, des bossages internes 18 qui délimitent chacun un alésage 19 pour le guidage d'un axe 20.Fig. 7 shows that the cover 8 has, below the seal 7, internal bosses 18 which each delimit a bore 19 for guiding an axis 20.

Un joint torique ou analogue 21 est interposé entre l'alésage 19 et l'axe 20. Chaque bossage 18 fait saillie au-dessus du couvercle 8, comme montré en 18a, et sert d'appui à un ressort de compression 28 qui est enveloppé par un fourreau 22 entourant également la partie saillante 18a tout en ménageant éventuellement un espace libre 23 entre sa base et le dessus du pot 8.An O-ring or the like 21 is interposed between the bore 19 and the axis 20. Each boss 18 protrudes above the cover 8, as shown in 18a, and serves to support a compression spring 28 which is wrapped by a sheath 22 also surrounding the projecting part 18a while optionally leaving a free space 23 between its base and the top of the pot 8.

Le fourreau 22 comporte un fond 22a contre lequel prend appui l'extrémité libre du ressort 28. Un manchon 24 est formé à partir du fond 22a et est enfilé et claveté sur l'extrémité 20a de l'axe 20.The sheath 22 has a bottom 22a against which the free end of the spring 28 bears. A sleeve 24 is formed from the bottom 22a and is threaded and keyed onto the end 20a of the axis 20.

Pour simplifier la fabrication, il est avantageux que l'extrémité 20a présente une section polygonale, par exemple carrée, qui soit complémentaire à la forme en section du manchon 24.To simplify manufacture, it is advantageous for the end 20a to have a polygonal section, for example square, which is complementary to the sectional shape of the sleeve 24.

De préférence, le manchon 24, le fourreau 22 et le levier 17 sont réalisés en une seule pièce par moulage d'une matière synthétique.Preferably, the sleeve 24, the sheath 22 and the lever 17 are made in one piece by molding a synthetic material.

Une vis 25 ou autre organe analogue assure la fixation du fourreau 22 sur l'axe 20.A screw 25 or other similar member secures the sheath 22 on the axis 20.

L'extrémité libre de l'axe 20 est fixée à la came 16 ou de préférence l'axe 20 et la came 16 sont fabriqués en une seule pièce par moulage d'un alliage métallique, par exemple un alliage ZnA1, pouvant être revêtu d'une couche protectrice, par exemple par nickelage ou chromage.The free end of the axis 20 is fixed to the cam 16 or preferably the axis 20 and the cam 16 are made in one piece by molding a metal alloy, for example a ZnA1 alloy, which can be coated with 'a protective layer, for example by nickel plating or chromium plating.

Les fig. 4 et 6 montrent que chaque came 16 présente, en plan, sensiblement la forme d'un secteur circulaire et la fig. 5 montre que le dessus 16a desdites cames 16 est conformé en voûte ou en coin.Figs. 4 and 6 show that each cam 16 has, in plan, substantially the shape of a circular sector and FIG. 5 shows that the top 16a of said cams 16 is shaped into a vault or a corner.

Le bossage 18, dans lequel est tourillonné l'axe 20, est prolongé par une bague 26 qui présente une encoche 27 s'étendant radialement, ainsi que l'illustrent les fig. 3 et 4.The boss 18, in which the axis 20 is journalled, is extended by a ring 26 which has a notch 27 extending radially, as illustrated in FIGS. 3 and 4.

Lorsque le couvercle 8 est séparé du pot 1, le levier 17 de commande de chaque came 16 est tourné dans une direction pour laquelle la came est dirigée vers l'intérieur du couvercle tout en reposant sur la base de la bague 26. Cela est représenté par les fig. 3 et 4.When the cover 8 is separated from the pot 1, the lever 17 for controlling each cam 16 is turned in one direction to which the cam is directed towards the inside of the cover while resting on the base of the ring 26. This is shown in FIGS. 3 and 4.

Pour mettre en place et verrouiller le couvercle 8 sur le pot 1, le couvercle est posé tout en étant guidé par les plots latéraux 9 de manière que le joint 7 repose sur le rebord 6.To set up and lock the cover 8 on the pot 1, the cover is placed while being guided by the side studs 9 so that the seal 7 rests on the flange 6.

Le joint 7 étant plat, il compense d'éventuelles différences de diamètre du rebord 6, ce qui se produit fréquemment selon la provenance des pots 1.The seal 7 being flat, it compensates for possible differences in diameter of the rim 6, which frequently occurs depending on the origin of the pots 1.

Dans cette position, le dessus des cames 16 se trouve dans un plan parallèle au plan délimité par la portée 5 de la couronne 3, mais en dessous de celle-ci.In this position, the top of the cams 16 is in a plane parallel to the plane delimited by the surface 5 of the crown 3, but below the latter.

En faisant pivoter les leviers 17, cela entraîne les cames 16 qui glissent contre le dessous de leur bague 26 respective jusqu'au moment où chaque came 16 entre dans l'encoche 27 sous l'action du ressort 21 qui tend à se détendre et qui soulève, par conséquent, l'axe 20 et la came 16.By pivoting the levers 17, this drives the cams 16 which slide against the underside of their respective ring 26 until the moment each cam 16 enters the notch 27 under the action of the spring 21 which tends to relax and which consequently raises the axis 20 and the cam 16.

Pendant la rotation des cames 16, celles-ci ne sont pas en contact avec la portée 5 de la couronne 3, ce qui élimine tout risque d'abrasion du vernis qui la recouvre. La longueur des cames permet de compenser d'éventuelles différences de diamètre de la partie 5.During the rotation of the cams 16, these are not in contact with the bearing surface 5 of the crown 3, which eliminates any risk of abrasion of the varnish which covers it. The length of the cams compensates for any differences in diameter of part 5.

L'invention n'est pas limitée aux exemples de réalisation, représentés et décrits en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. En particulier, la forme de la couronne 3 peut être différente de celle illustrée à titre d'exemple et, de même, le mouvement axial qui est conféré aux cames de verrouillage en position de fermeture peut être assuré autrement que par une bague 26.The invention is not limited to the exemplary embodiments, shown and described in detail, since various modifications can be made thereto without departing from its scope. In particular, the shape of the crown 3 can be different from that illustrated by way of example and, likewise, the axial movement which is imparted to the locking cams in the closed position can be ensured other than by a ring 26.

Il est possible en effet de prévoir à l'intérieur du bossage 18 une rampe pour un doigt ou un filet de vis que présenterait l'axe 20.It is indeed possible to provide inside the boss 18 a ramp for a finger or a screw thread that the axis 20 would have.
