Cover made of flexible plastic material, particularly for metal buckets whose opening has a rolled edge. According to the invention, the cover comprises a dish (14) whose raised edge is provided with a first annular wall (16), connected to an external skirt (18) by the intermediary of an annular portion whose internal face is curved to cooperate with the rounded edge of the opening of the container, this curved face and/or the external face of the said first annular wall (16) being provided with flexible lips (24, 22). The invention makes it possible to improve the strength of the package when it is dropped and to improve resistance to internal air pressure.

Description

"Couvercle en matière plastique souple pour récipient
à bord arrondi"
L'invention se rapporte à un couvercle en matière plastique souple pour un récipient à bord arrondi et notamment un seau formant emballage d'un produit liquide ou pâteux comme par exemple un seau métallique muni d'un bord roulé."Soft plastic cover for container
with rounded edge "
The invention relates to a flexible plastic cover for a container with a rounded edge and in particular a bucket forming a packaging for a liquid or pasty product such as for example a metal bucket provided with a rolled edge.

Pour assujettir efficacement un couvercle métallique pendant le transport et le stockage, il est généralement nécessaire de prévoir une bande métallique formant collier, serrée tout autour du couvercle. Lors de la première ouverture du récipient, il est nécessaire de rompre cette bande métallique à l'aide d'un outil. I1 en résulte des déformations mineures du bouchon et/ou du récipient, ce qui nuit à une fermeture ultérieure de l'emballage, si le produit n'est pas consommé en une seule fois. To effectively secure a metal cover during transport and storage, it is generally necessary to provide a metal band forming a collar, tightened all around the cover. When the container is opened for the first time, it is necessary to break this metal strip using a tool. This results in minor deformations of the stopper and / or of the container, which hinders a subsequent closing of the packaging, if the product is not consumed all at once.

L'invention concerne un couvercle en matière plastique souple qui ne présente pas ce genre d'inconvénient tout en offrant une sécurité de fermeture comparable. The invention relates to a flexible plastic cover which does not have this kind of drawback while offering comparable closing security.

Plus précisément, l'invention concerne donc un couvercle en matière plastique souple pour récipient à bord arrondi, tel qu'un seau métallique muni d'un bord roulé, caractérisé en ce qu'il comporte une cuvette munie d'une première paroi annulaire à section sensiblement rectiligne, conformée et dimensionnée pour prendre appui contre la face interne dudit récipient, en ce que cette paroi annulaire est prolongée extérieurement par une jupe approximativement parallèle à ladite paroi annulaire et s'y raccordant par une portion annulaire dont la face interne au moins est courbe et conformée pour épouser au moins en partie ledit bord arrondi et en ce que la face extérieure de ladite paroi annulaire et/ou ladite face interne courbe sont munies d'au moins une lèvre d'étanchéité s'étendant sur tout un contour d'une telle face. More specifically, the invention therefore relates to a flexible plastic cover for a container with a rounded edge, such as a metal bucket provided with a rolled edge, characterized in that it comprises a bowl provided with a first annular wall with substantially straight section, shaped and dimensioned to bear against the internal face of said container, in that this annular wall is extended externally by a skirt approximately parallel to said annular wall and connected thereto by an annular portion whose internal face at least is curved and shaped to match at least partially said rounded edge and in that the outer face of said annular wall and / or said curved inner face are provided with at least one sealing lip extending over a whole contour d 'such a face.

L'invention s'applique particulièrement à un couvercle pour un seau métallique à ouverture circulaire et dans ce cas, un tel couvercle a globalement la forme d'un disque creux avantageusement conformé pour permettre l'empilabilité de tels seaux fermés par de tels couvercles. De tels couvercles sont également de préférence prévus avec des moyens d'espacement axial permettant l'empilabilité de tels couvercles entre eux en vue d'une distribution automatique sur une chaîne de remplissage et de fermeture des récipients. The invention is particularly applicable to a cover for a metal bucket with circular opening and in this case, such a cover generally has the shape of a hollow disc advantageously shaped to allow the stacking of such buckets closed by such covers. Such covers are also preferably provided with axial spacing means allowing the stacking of such covers with one another for automatic distribution on a filling and closing chain for the containers.

La forme du couvercle, telle que définie ci-dessus assure une bonne étanchéité de la fermeture en cas de chute tout en permettant le roulage du récipient pendant les manutentions. L'emballage présente également une très bonne résistance à la pression ou à la dépression interne. The shape of the cover, as defined above ensures good sealing of the closure in the event of a fall while allowing the container to roll during handling. The packaging also has very good resistance to internal pressure or vacuum.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation actuellement préféré d'un couvercle conforme à son principe, donnée à titre d'exemple et faite en référence aux dessins annexés dans lesquels:
- La figure 1 est une vue générale en coupe diamétrale d'un couvercle conforme à l'invention, représenté en place sur l'ouverture d'un seau métallique à bord roulé;
- La figure 2 est une vue à plus grande échelle de la partie du couvercle seul située dans l'encadré 2 de la figure 1.The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a currently preferred embodiment of a cover in accordance with its principle, given by way of example and made with reference to the accompanying drawings in which:
- Figure 1 is a general view in diametral section of a cover according to the invention, shown in place on the opening of a metal bucket with a rolled edge;
- Figure 2 is an enlarged view of the part of the cover alone located in Box 2 of Figure 1.

Sur les dessins, on a représenté un seau métallique 11, à bord roulé 12 fermé par- un couvercle en matière plastique souple 13 conforme à l'invention. Le seau métallique 11 présente ici une ouverture circulaire de sorte que le couvercle 13 a globalement la forme d'un disque présentant une cuvette 14 à fond 15 plat. Le bord relevé de la cuvette présente une première paroi annulaire 16, à section sensiblement rectiligne, c'est-à-dire ici de forme globalement cylindrique conformée et dimensionnée pour prendre appui par sa face extérieure 17 contre la face interne du seau 11, au voisinage de l'ouverture à bord roulé de ce dernier.Ladite paroi annulaire 16 est prolongée extérieurement par une jupe 18 approximativement parallèle et s'y raccordant par une portion annulaire 19 dont la face interne 20 au moins est courbe et conformée pour épouser, au moins en partie, le bord arrondi 12 du récipient, c'est-àdire ici le bord roulé du seau métallique. De plus, la face extérieure 17 de ladite première paroi annulaire 16 et/ou la face interne courbe 20 sont munies d'au moins une lèvre d'étanchéité souple s'étendant sur tout un contour d'une telle face. Plus précisément, ladite face extérieure 17 est munie d'une lèvre souple 22 tandis que la face interne courbe 20 comporte une lèvre 24. Chacune de ces lèvres a un profil radial dissymétrique, comme cela est clairement visible sur la figure 2.De plus, la face intérieure de la jupe 18 comporte une nervure d'emboîtement 26 définie au voisinage du raccordement entre ladite jupe et ladite portion annulaire 19. Cette nervure est conformée et dimensionnée pour coopérer avec la partie inférieure du bord arrondi du récipient, c'est-à-dire le bord roulé 12. In the drawings, a metal bucket 11 has been shown, with a rolled edge 12 closed by a flexible plastic cover 13 according to the invention. The metal bucket 11 has here a circular opening so that the cover 13 is generally in the form of a disc having a bowl 14 with a flat bottom. The raised edge of the bowl has a first annular wall 16, of substantially rectilinear section, that is to say here of generally cylindrical shape shaped and dimensioned to bear by its external face 17 against the internal face of the bucket 11, at vicinity of the opening with a rolled edge of the latter. Said annular wall 16 is extended externally by an approximately parallel skirt 18 and connected thereto by an annular portion 19 of which the internal face 20 at least is curved and shaped to match, at less in part, the rounded edge 12 of the container, that is to say here the rolled edge of the metal bucket. In addition, the external face 17 of said first annular wall 16 and / or the curved internal face 20 are provided with at least one flexible sealing lip extending over a whole contour of such a face. More specifically, said external face 17 is provided with a flexible lip 22 while the curved internal face 20 comprises a lip 24. Each of these lips has an asymmetrical radial profile, as is clearly visible in FIG. 2. the inner face of the skirt 18 has an interlocking rib 26 defined in the vicinity of the connection between said skirt and said annular portion 19. This rib is shaped and dimensioned to cooperate with the lower part of the rounded edge of the container, that is i.e. the rolled edge 12.

De plus, l'étanchéité de la fermeture est améliorée par le fait que la portion extrême de ladite paroi annulaire 16, opposée à la portion annulaire 19 est légèrement inclinée vers l'extérieur. Autrement dit, ladite portion extrême 28 est légèrement tronconique et se trouve comprimée lorsque le couvercle est en position sur l'ouverture du récipient. Une conicité c relativement faible, visible sur la figure 2, suffit à renforcer efficacement l'étanchéité à ce niveau. In addition, the sealing of the closure is improved by the fact that the end portion of said annular wall 16, opposite the annular portion 19 is slightly inclined outward. In other words, said end portion 28 is slightly frustoconical and is compressed when the cover is in position on the opening of the container. A relatively small taper c, visible in Figure 2, is sufficient to effectively strengthen the seal at this level.

-Selon une autre caractéristique remarquable de ce couvercle, la cuvette 14 comporte une seconde paroi annulaire 30, à section sensiblement rectiligne, plus petite que ladite première paroi annulaire plate et raccordée à celle-ci par une paroi annulaire inclinée 32, ici tronconique. Comme cela est visible sur la figure 1, cette forme de la cuvette 14 permet l'empilabilité des seaux 11 équipés de tels couvercles. A cet effet, un tel seau 11 est muni d'un fond présentant un rétreint 34 venant se loger dans la partie de la cuvette définie par le fond 15 et ladite seconde paroi annulaire 30.  -According to another remarkable characteristic of this cover, the bowl 14 comprises a second annular wall 30, of substantially rectilinear section, smaller than said first flat annular wall and connected to the latter by an inclined annular wall 32, here frustoconical. As can be seen in Figure 1, this shape of the bowl 14 allows the stackability of the buckets 11 equipped with such covers. To this end, such a bucket 11 is provided with a bottom having a constriction 34 which is received in the part of the bowl defined by the bottom 15 and said second annular wall 30.

Comme représenté sur la figure 1, le seau 11 comporte avantageusement un jonc 36 faisant saillie de la paroi latérale du seau, à peu de distance du bord roulé 12. En position de fermeture, l'extrémité inférieure de la jupe 18 vient au voisinage immédiat de ce jonc, ce qui empêche tout soulèvement accidentel du couvercle, notamment pendant les transports, du fait que l'arrachement du couvercle à partir du bord circulaire de la jupe devient impossible et que les seaux prennent contact les uns avec les autres par l'intermédiaire de ce jonc. As shown in FIG. 1, the bucket 11 advantageously comprises a rod 36 projecting from the side wall of the bucket, a short distance from the rolled edge 12. In the closed position, the lower end of the skirt 18 comes in the immediate vicinity of this rod, which prevents any accidental lifting of the cover, especially during transport, because the tearing of the cover from the circular edge of the skirt becomes impossible and the buckets make contact with each other by the intermediate of this rod.

De plus, des nervures 38, s'étendant ici radialement sont venues de moulage avec les faces extérieures de ladite paroi annulaire inclinée 32 et de ladite seconde paroi annulaire 30. Ces nervures donnent une meilleure rigidité à la partie périphérique du couvercle et, surtout, assurent ltempilabilité de couvercles semblables permettant une distribution automatique de tels couvercles, pendant les opérations de remplissage et de fermeture des seaux. In addition, ribs 38, extending here radially, have come from molding with the outer faces of said inclined annular wall 32 and of said second annular wall 30. These ribs give better rigidity to the peripheral part of the cover and, above all, ensure the stackability of similar lids allowing automatic distribution of such lids, during the filling and closing operations of the buckets.

Le couvercle comporte une languette latérale 40 pour l'ouverture du seau par arrachement du couvercle souple. The cover has a lateral tab 40 for opening the bucket by tearing off the flexible cover.

Cette languette est rattachée à la jupe 18. Ce rattachement, venu de moulage, est renforcé par des nervures 41 s'étendant entre la face interne de la languette et la face extérieure de la jupe 18.
