Description

La présente invention concerne un dispositif de fermeture hermétique d'un récipient et plus particulièrement de pots ou bacs à peinture à ouverture totale.The present invention relates to a device for hermetically closing a container and more particularly paint cans or tubs with full opening.

De manière classique, la fermeture de tels réci­pients s'effectue par des couvercles sertis. On connait aussi des couvercles munis de pattes latérales périphériques rabattues sous un rebord du corps du récipient.Conventionally, the closure of such containers is effected by crimped lids. Lids are also known which are provided with peripheral lateral tabs folded under a rim of the body of the container.

On a également proposé des couvercles de type rentrant impliquant un enfoncement de la partie rentrante du couvercle dans le récipient, la sécurité de la fermeture étant obtenue par frottement de cette partie rentrante contre les parois internes du récipient.Lids of the re-entrant type have also been proposed, implying a recess of the re-entrant part of the cover into the container, the security of the closure being obtained by rubbing this re-entrant part against the internal walls of the container.

De tels couvercles de fermeture couramment uti­lisés dans ce domaine présentent des inconvénients . D'abord, après la première ouverture, la fermeture du réci­pient n'est plus hermétique, de sorte que le produit res­tant peut se détériorer jusqu' à devenir inutilisable. Les dispositifs connus présentent aussi des dangers de manipu­lation par exemple des risques de coupures de l'utilisa­teur.Such closure covers commonly used in this field have drawbacks. First, after the first opening, the closure of the container is no longer hermetic, so that the remaining product can deteriorate until it becomes unusable. Known devices also present handling dangers, for example risks of cuts by the user.

Pour remédier à ces différents inconvénients, il a été proposé (voir par exemple brevet FR-1.395.943) des dis­positifs de fermeture mettant en oeuvre une bague intermé­diaire en matière plastique montée élastiquement en chevau­chement sur le bord supérieur du corps pour assurer en combinaison avec le couvercle la fermeture du récipient grâce à des moyens de verrouillage élastiques réalisés sur ladite bague.To overcome these various drawbacks, it has been proposed (see for example patent FR-1,395,943) closing devices using an intermediate ring made of plastic elastically mounted overlapping on the upper edge of the body to ensure in combination with the lid closing the container by means of elastic locking means produced on said ring.

En outre, de telles bagues en matière plastique permettent d'intégrer, grâce aux techniques de moulage, des éléments de suspension pour introduction des extrémités d'une anse de préhension, alors que jusqu'alors ces éléments étaient constitués par des cabochons métalliques à souder sur le corps du récipient, d'où opérations supplémentaires et surtout risques d'oxydation des parois dudit récipient.In addition, such plastic rings make it possible to integrate, thanks to molding techniques, suspension elements for introduction of the ends of a grip handle, whereas until then these elements consisted of metal cabochons to be welded. on the body of the container, hence additional operations and above all risks of oxidation of the walls of said container.

Bon nombre de ces dispositifs à bague intermé­diaire en matière plastique, s'ils ont résolu pratiquement les inconvénients précités, en ont par contre créé d'autres, révélés par l'usage.Many of these devices with an intermediate ring made of plastic, if they have practically solved the aforementioned drawbacks, have on the other hand created others, revealed by use.

En effet, de telles bagues intermédiaires en matière plastique interposées entre corps et couvercle et montées en chevauchement sur le rebord dudit corps, ont nécessairement une partie située à l'extérieur du corps et une partie située à l'intérieur du corps. Cette dernière sera en conséquence en contact direct avec le contenu, de la peinture en l'occurrence, en cours de stockage. Si l'on dispose d'un couvercle du type rentrant de hauteur suffi­sante pour protéger en stockage la partie interne de la bague plastique, les inconvénients précités demeurent lors du remplissage et de l'utilisation. La bague doit être protégée du contact avec la peinture de manière absolue car on rencontre souvent une incompatibilité du matériau plas­tique avec certains constituants des peintures par exemple, des produits organiques, des solvants aromatiques, tels que esters ou cétones, qui ont pour effet de modifier les caractéristiques mécaniques de ladite bague.Indeed, such intermediate rings of plastic material interposed between body and cover and mounted overlapping on the rim of said body, necessarily have a part located outside the body and a part located inside the body. The latter will therefore be in direct contact with the content, the paint in this case, during storage. If there is a cover of the re-entrant type of sufficient height to protect the internal part of the plastic ring in storage, the aforementioned drawbacks remain during filling and use. The ring must be protected from contact with paint in an absolute way because we often encounter an incompatibility of the plastic material with certain constituents of paints for example, organic products, aromatic solvents, such as esters or ketones, which have the effect of modifying the mechanical characteristics of said ring.

La présente invention vise à remédier à ces in­convénients en isolant absolument la bague du contenu du récipient tout en procurant une étanchéité sûre.The present invention aims to remedy these drawbacks by absolutely isolating the ring from the contents of the container while providing a secure seal.

Dans ce but, elle concerne un dispositif de fermeture hermétique d'un récipient notamment d'un pot ou bac à peinture, du type comprenant un corps contenant dont une de ses extrémités ouverte totalement est susceptible d'être fermée par un couvercle rentrant amovible, par l'intermédiaire d'une bague périphérique apte à coopérer étroitement d'une part avec un rebord de l'extrémité ouverte et d'autre part avec ledit couvercle pour assurer en combi­naison avec celui-ci la fermeture hermétique du récipient caractérisée en ce que la bague périphérique est disposée entièrement sur le pourtour externe dé l'extrémité ouverte du corps, en dehors de cette dernière et à proximité immé­diate du rebord avec lequel elle coopère.To this end, it relates to a device for hermetically closing a container, in particular a pot or paint tray, of the type comprising a container body, one of its ends of which is fully open and capable of being closed by a removable re-entrant cover, by means of a peripheral ring able to cooperate closely on the one hand with a rim of the open end and on the other hand with said lid to ensure in combination with the latter the hermetic closure of the container, characterized in that the peripheral ring is disposed entirely on the outer periphery of the open end of the body, outside the latter and in the immediate vicinity of the rim with which it cooperates.

La présente invention concerne également les caractéristiques ci-après considérées isolément ou selon toutes leurs combinaisons techniques possibles.The present invention also relates to the characteristics below considered in isolation or according to all of their possible technical combinations.

Selon une autre caractéristique de l'invention, des moyens de retenue axiale de la bague sur le corps contenant sont constitués par une collerette périphérique interne de la bague apte à s'encliqueter élastiquement au montage dans au moins deux logements opposés délimités chacun par une partie inférieure du rebord, une partie supérieure d'une saillie externe du corps contenant et la paroi externe même de celui-­ci constituant le fond des logements.According to another characteristic of the invention, means for axially retaining the ring on the container body are constituted by an internal peripheral flange of the ring capable of snap-in elastically during mounting in at least two opposite housings each delimited by a part lower edge, an upper part of an external projection of the container body and the same external wall thereof constituting the bottom of the housings.

De plus, la saillie constitutive d'une partie du logement de retenue axiale de la bague est obtenue par emboutissage de la matière du corps contenant, dans une direction sensiblement parallèle au rebord dudit corps et se décompose en deux parties laissant subsister entre elles un passage non embouti.In addition, the projection constituting a part of the axial retaining housing of the ring is obtained by stamping the material of the container body, in a direction substantially parallel to the edge of said body and is broken down into two parts leaving a passage between them. not stamped.

Selon un exemple de réalisation, le corps contenant est de forme tronc-pyramidale à section rectangulaire à angles arrondis ou à section circulaire, dont la grande base constitue son extrémité ouverte et la petite base, le fond, la bague, dont la section a une forme correspondant sensible­ment à celle du corps, étant, au montage, introduite à partir du fond jusqu'à sa position de retenue au voisinage du rebord.According to an exemplary embodiment, the container body is of trunk-pyramidal shape with rectangular section with rounded angles or with circular section, the large base of which constitutes its open end and the small base, the bottom, the ring, the section of which has a shape corresponding substantially to that of the body, being, during assembly, introduced from the bottom to its retaining position in the vicinity of the rim.

De cette manière, il se produira, après encliquetage élastique de la bague sur ses moyens de retenue, un serrage de celle-ci sur le corps.In this way, it will occur, after elastic snap-fastening of the ring on its retaining means, a tightening of the latter on the body.

Une telle bague ainsi constituée est avantageusement obtenue par moulage de matière plastique et des dépouilles de démoulage sont telles à les rendre empilables et distribua­bles automatiquement.Such a ring thus formed is advantageously obtained by molding of plastic material and release molds are such as to make them stackable and distributable automatically.

Selon une autre caractéristique de l'invention, des moyens d'encliquetage élastique du couvercle sur la bague sont constitués par des parties saillantes en forme de crochets s'étendant à une partie supérieure de ladite bague, dirigés vers l'intérieur de celle-ci en suivant son profil périphérique et sous lesquels est susceptible de venir se loger sur un bord du couvercle, lequel vient en appui sur le rebord du corps contenant.According to another characteristic of the invention, elastic snap-fastening means of the cover on the ring consist of hook-shaped projecting parts extending to an upper part of said ring, directed towards the inside thereof by following its peripheral profile and under which is susceptible to come to lodge on an edge of the cover, which comes to bear on the rim of the container body.

Selon un mode préférentiel de réalisation, le bord du couvercle se prolonge par une zone d'extrémité périphéri­que de section en forme de goulotte dont l'extrémité libre est dirigée au montage dans une direction opposée à celle des crochets de la bague, avec lesquels ladite zone d'extrémité coopère en verrouillage.According to a preferred embodiment, the edge of the cover is extended by a peripheral end zone of section in the form of a chute, the free end of which is directed for mounting in a direction opposite to that of the hooks of the ring, with which said end zone cooperates in locking.

Avantageusement, le rebord de l'extrémité ouverte du corps est un roulé tourné vers l'extérieur obtenu par conformation de ladite extrémité ouverte.Advantageously, the rim of the open end of the body is a rolled outwardly turned obtained by conformation of said open end.

De manière à permettre la préhension aisée du récipient, la bague comporte, obtenus de moulage avec elle, deux oreillons de suspension du récipient, disposés en opposition et constitués par deux logements en forme de boutonnières ouvertes au fond desquelles sont aptes à se loger les extrémités libres d'une anse.In order to allow easy gripping of the container, the ring comprises, obtained from molding with it, two suspension suspension pins for the container, arranged in opposition and constituted by two housings in the form of open buttonholes at the bottom of which are capable of accommodating the ends free from a handle.

Enfin, il peut être prévu un surcouvercle qui coiffe la partie supérieure du récipient fermé et comporte des parties respectivement aptes à exercer simultanément une pression axiale sur le couvercle et une pression latérale sur la partie supérieure de la bague au voisinage des crochets après fixation sur ladite bague.Finally, an overcap can be provided which covers the upper part of the closed container and comprises parts respectively capable of simultaneously exerting axial pressure on the cover and lateral pressure on the upper part of the ring in the vicinity of the hooks after attachment to said Ring.

Un tel surcouvercle est fixé sur la bague par encliquetage élastique d'un bourrelet interne périphérique obtenu à l'extrémité libre de la partie ouverte d'engagement dudit surcouvercle dans une pluralité de logements de retenue obtenus de matière à la partie inférieure externe de la bague.Such an overcap is fixed to the ring by elastic snap-fastening of a peripheral internal bead obtained at the free end of the open engagement part of said overcap in a plurality of retaining housings obtained from material at the lower external part of the ring. .

Bien que dans la présente description il ait été mentionné que le rebord du corps contenant est un rebord roulé de même que l'encliquetage élastique du surcouvercle est un bourrelet, l'homme de métier comprendra que ces parties peuvent aussi être constituées par des rebords plats ou partiellement recourbés, leur fonction étant celle de constituer des surfaces d'appui et d'accrochage.Although in the present description it has been mentioned that the rim of the container body is a rolled rim just as the elastic snap of the overcap is a bead, the person skilled in the art will understand that these parts can also be constituted by flat or partially curved rims, their function being that of constitute support and attachment surfaces.

Le dispositif de fermeture représenté à la Figure 1 montre d'une manière globale un récipient 1, notamment un bac à peinture du type comprenant un corps contenant 2 constitué de manière connue d'une enveloppe latérale en l'occurrence de section rectangulaire issue ou rapportée sur un fond 4 a l'une de ses extrémités, l'autre extrémité opposée consti­tuant une ouverture totale 5 susceptible d'être fermée par un couvercle 6 rentrant, amovible s 'emboîtant par friction dans le corps contenant 2, sa fixation étant rendue effective par l'intermédiaire d'une bague périphérique 7 rendue apte à coopérer étroitement d'une part avec un rebord 8 de l'extré­mité ouverte 5 du corps contenant 2 et d'autre part avec ledit couvercle 6 pour assurer en combinaison la fermeture hermétique du récipient 1.The closing device shown in Figure 1 generally shows a container 1, in particular a paint tray of the type comprising a body containing 2 consisting in a known manner of a lateral envelope in this case of rectangular section issuing from or attached to a bottom 4 to one of its ends, the other opposite end constituting a total opening 5 capable of being closed by a re-entrant, removable cover 6 interlocking by friction in the container body 2, its fixing being made effective by means of a peripheral ring 7 made capable of cooperating closely on the one hand with a rim 8 of the open end 5 of the body containing 2 and on the other hand with said cover 6 in order to ensure the hermetic closure of the container 1 in combination.

Selon l'invention, la bague périphérique 7 est disposée entièrement sur le pourtour externe 2a à proximité de l'extrémité ouverte 5 du corps 2, en dehors du plan de ladite extrémité 5 et à proximité immédiate du rebord 8 avec lequel elle coopère de manière telle à échapper totalement au produit lors de l'opération de remplissage et aussi après fermeture du couvercle rentrant 6.According to the invention, the peripheral ring 7 is disposed entirely on the outer periphery 2a near the open end 5 of the body 2, outside the plane of said end 5 and adjacent the rim 8 with which it cooperates in such a way as to completely escape the product during the filling operation and also after closing the re-entrant cover 6.

Dans un premier exemple de réalisation, le corps contenant 2 est en forme de tronc de pyramide à section rectangulaire et à angles arrondis 10 dont la grande base est constituée par son extrémité ouverte 5 et sa petite base par le fond 4 constituant également le côté d'introduction allant du bas vers le haut au montage, de la bague 7, laquelle bague a une section de forme correspondante à celle du corps 2 définie plus haut et ses dimensions sensiblement inférieures à celles de l'ouverture 5 de manière telle à être immobilisée par serrage lors de sa venue en butée sous le rebord 8 faisant office de butoir périphérique.In a first embodiment, the body containing 2 is in the form of a pyramid trunk with rectangular section and rounded corners 10, the large base of which is constituted by its open end 5 and its small base by the bottom 4 also constituting the side d 'introduction going from bottom to top during assembly, of the ring 7, which ring has a cross section corresponding to that of the body 2 defined above and its dimensions substantially smaller than those of the opening 5 so as to be immobilized by clamping when it comes into abutment under the rim 8 serving as a peripheral stop.

La bague 7 ainsi disposée est retenue axialement sur le corps 2 par des moyens constitués par une collerette périphérique interne 11 obtenue par moulage de matière plastique avec la bague 7, de dimensions telles à pouvoir s'encliqueter élastiquement lors du montage dans des loge­ments 12, chacun d'eux étant délimité par trois éléments à savoir : une partie inférieure 8a du rebord 8, une partie supérieure 13a d'une saillie externe 13 du corps contenant 2 set la paroi externe 2a même dudit corps 2 constituant le fond de chaque logement 12.The ring 7 thus arranged is retained axially on the body 2 by means constituted by an internal peripheral flange 11 obtained by molding of plastic material with the ring 7, of dimensions such as to be able snap in when mounting in housings 12, each of them being delimited by three elements, namely: a lower part 8 has the rim 8, an upper part 13 has an external projection 13 of the body containing 2 set the external wall 2 a same of said body 2 constituting the bottom of each housing 12.

La saillie 13, partie constitutive du logement 12, est avantageusement obtenue par emboutissage de la matière du corps 2, de préférence métallique, de manière parallèle au rebord 8 en formant une section semi-circulaire pour consti­tuer une pente douce de passage, puis de glissement vers une position d'immobilisation définitive dans les logements 12.The projection 13, constitutive part of the housing 12, is advantageously obtained by stamping the material of the body 2, preferably metallic, parallel to the flange 8 by forming a semi-circular section to form a gentle slope for passage, then sliding towards a position of final immobilization in the housings 12.

Dans un mode préférentiel de réalisation représenté à la Figure 1 dans une configuration rectangulaire, les saillies 13 sont au nombre de quatre et situées sur les angles arrondis 10 sur un même plan. Chaque saillie 13 se décompose en deux parties (non représentées) laissant subsister entre elles une partie non emboutie située sur une génératrice du bord arrondi 10 pour permettre le passage d'une des nervures 14 de renfort de la bague 7 située perpendiculairement sous la collerette 11 pour constituer des équerres de renforcement de cette dernière par rapport à une ceinture 15 de la bague 2.In a preferred embodiment shown in Figure 1 in a rectangular configuration, the projections 13 are four in number and located on the rounded corners 10 on the same plane. Each projection 13 is broken down into two parts (not shown) leaving between them a non-stamped part located on a generatrix of the rounded edge 10 to allow the passage of one of the ribs 14 for reinforcing the ring 7 located perpendicularly under the flange 11 to constitute reinforcement brackets for the latter relative to a belt 15 of the ring 2.

La bague 2 ainsi conçue et ainsi disposée et fixée sur le corps contenant 2 est apte à recevoir le couvercle de fermeture 6 grâce à des moyens d'encliquetage élastiques.The ring 2 thus designed and thus arranged and fixed on the container body 2 is able to receive the closure cover 6 by means of elastic snap-fastening means.

Ces moyens sont constitués par une pluralité de parties saillantes en forme de crochets 16 obtenus à une partie supérieure de ladite bague 2, dirigés vers l'intérieur de celle-ci en suivant son profil périphérique et reliées entre elles par un voile 21 pour le moins dans ses parties rectilignes. Ces crochets 16 comportent des becquets 17 aptes à s'escamoter élastiquement au passage d'une zone d'extrémité périphérique 18 du couvercle 6, formant une goulotte 19, et dirigée, dans un sens axial de montage, dans une direction opposée à celle des becquets 17 avec lesquels coopère ladite zone d'extrémité périphérique formant arête après retour en position initiale.These means are constituted by a plurality of hook-shaped projecting parts 16 obtained at an upper part of said ring 2, directed towards the inside of the latter by following its peripheral profile and connected together by a web 21 at least. in its rectilinear parts. These hooks 16 comprise spoilers 17 able to retract elastically when a peripheral end zone 18 of the cover 6 passes, forming a chute 19, and directed, in an axial mounting direction, in a direction opposite to that of the spoilers 17 with which said peripheral end region forming an edge cooperates after returning to the initial position.

Selon une variante de réalisation (Fig. 8), la zone d'extrémité 18A du couvercle 6A forme un roulé coopérant de manière identique avec les becquets 17 de la bague 7, mais offrant l'avantage d'assurer à l'utilisateur une protection contre les coupures.According to an alternative embodiment (FIG. 8), the end zone 18A of the cover 6A forms a roll cooperating in an identical manner with the spoilers 17 of the ring 7, but offering the advantage of providing the user with protection against cuts.

Un joint périphérique 20 peut être interposé, pour une meilleure étanchéité, entre le rebord 8 et le couvercle 6, de manière telle à subir une compression élastique au montage. Dans le présent exemple de réalisation, le rebord 8 du corps 2 est un roulé 22 tourné vers l'extérieur obtenu par conformation de l'extrémité ouverte 5.A peripheral seal 20 can be interposed, for better sealing, between the flange 8 and the cover 6, so as to undergo elastic compression during assembly. In the present embodiment, the rim 8 of the body 2 is a roll 22 facing outwards obtained by shaping the open end 5.

Etant donné l'obtention de la bague 7 par moulage de matière plastique, il est avantageux de prévoir au cours de la même opération deux oreillons de suspension 23 du réci­pient 1 disposés en opposition comme le montre la Figure 5, et constitués par deux logements, en forme de boutonnières 24 et au fond desquelles sont aptes à se loger les extrémités libres 25 d'une anse 26 après passage d'un rétrécissement 27 des boutonnières 24, déformable élastiquement.Given the obtaining of the ring 7 by molding of plastic material, it is advantageous to provide during the same operation two suspension mumps 23 of the container 1 arranged in opposition as shown in FIG. 5, and constituted by two housings, in the form of buttonholes 24 and at the bottom of which are able to accommodate the free ends 25 of a handle 26 after passage of a narrowing 27 of the buttonholes 24, elastically deformable.

Selon une autre caractéristique de l'invention, un surcouvercle métallique 28 coiffe la partie supérieure du récipient 1 tel que défini ci-dessus et fermé par le couver­cle 6. Un tel surcouvercle 28 comporte des données A et B respectivement aptes à exercer simultanément une pression axiale sur le couvercle 6 en A et une pression latérale périphérique sur la partie supérieure de la bague 7 en B, au voisinage des crochets 16, après fixation du surcouvercle 28 sur ladite bague 2 s'effectuant par encliquetage élastique d'un bourrelet interne périphérique 29, en l'occurence un roulé également, obtenu à l'extrémité libre 30 de la partie ouverte d"engagement dudit surcouvercle, dans une pluralité de logements de retenue 31 constitués par des proéminences 32 venues de matière avec la bague 7 à sa partie inférieure 7a.According to another characteristic of the invention, a metal overcap 28 covers the upper part of the container 1 as defined above and closed by the cover 6. Such an overcap 28 includes data A and B respectively capable of exerting pressure simultaneously axial on the cover 6 in A and a lateral lateral pressure on the upper part of the ring 7 in B, in the vicinity of the hooks 16, after fixing of the overcap 28 on said ring 2 being effected by elastic snap-fastening of an internal peripheral bead 29, in this case also a roll, obtained at the free end 30 of the open engagement part of said overcap, in a plurality of retaining housings 31 constituted by protrusions 32 mating with the ring 7 at its lower part 7 a .

L'avantage résultant d'un surcouvercle obtenu en matière métallique réside dans le fait de pouvoir permettre à l'utilisateur d'y poser son rouleau ou son pinceau au cours d'une pause.The advantage resulting from an overcap obtained in metallic material lies in the fact of being able to allow the user to place his roller or his brush there during a break.

Comme visible à la Figure 2, un espace 32 est ménagé entre le surcouvercle 28 et le couvercle 6 dans le but de constituer un compartiment destiné à recevoir par exemple une documentation technique concernant le produit.As shown in Figure 2, a space 32 is provided between the overcap 28 and the cover 6 in order to form a compartment intended to receive for example technical documentation concerning the product.

Le récipient 1A montré à la Figure 4 diffère essentiellement du mode de réalisation précédent en ce que sa section est circulaire et que les moyens de retenue axiale de la bague et d'encliquetage élastique du couvercle sont, ainsi que les moyens de verrouillage du surcouvercle, équitablement répartis de manière circulaire.The container 1A shown in FIG. 4 essentially differs from the previous embodiment in that its section is circular and that the means for axial retention of the ring and elastic snap-fastening of the cover are, as well as the means for locking the over-cover, evenly distributed in a circular fashion.

Enfin, il est à noter que chacune des parties constitutives du récipient 1, à savoir : le corps 2, la bague 7, le couvercle 6 et le surcouvercle 28 sont empilables et distribuables automatiquement. En ce qui concerne le corps 2 et pour éviter son coincement lors de l'empilage à l'état vide, des nervures 33 sont prévues aux quatres angles dudit corps 2.Finally, it should be noted that each of the constituent parts of the container 1, namely: the body 2, the ring 7, the cover 6 and the overcap 28 are stackable and distributable automatically. As regards the body 2 and to avoid its jamming during stacking in the empty state, ribs 33 are provided at the four corners of said body 2.

De plus, et à l'exclusion du corps 2, du couvercle 6 et du surcouvercle 28, avantageusement métalliques dans le présent exemple, toutes les autres parties sont obtenues par moulage de matière plastique.In addition, and with the exclusion of the body 2, the cover 6 and the over-cover 28, advantageously metallic in the present example, all the other parts are obtained by molding of plastic material.
