Description

L'invention se rapporte à un couvercle métallique pour un récipient étanche, tel que par exemple un seau métallique destiné au transport de matières dangereuses; elle concerne plus particulièrement un perfectionnement permettant d'améliorer la résistance mécanique du couvercle, notamment vis-à-vis des tests habituels de chute et de résistance à la pression interne.The invention relates to a metal cover for a sealed container, such as for example a metal bucket intended for the transport of hazardous materials; it relates more particularly to an improvement making it possible to improve the mechanical resistance of the cover, in particular with respect to the usual tests for drop and resistance to internal pressure.

On connaît un couvercle métallique plus particulièrement destiné à fermer de façon étanche un récipient de relativement grande dimension. Un tel couverc comprend une paroi centrale située en contrebas du sommet d'une jupe périphérique fragmentée extérieurement de façon à définir des pattes de sertissage. Autrement dit, le couvercle est pourvu d'un rebord à profil radial en U inversé, les pattes de sertissage étant individualisées dans la paroi annulaire extérieure de ce rebord. Un joint d'étanchéité est logé dans l'espace périphérique défini par le rebord à profil en U. Les pattes sont prévues pour être assemblées à un rebord arrondi du récipient (généralement défini par un roulé), par refoulement radial vers l'intérieur. Ce sertissage a pour effet d'appliquer le joint contre le rebord du récipient pour assurer une fermeture étanche.A metal cover is known more particularly intended for sealingly closing a relatively large container. Such a cover comprises a central wall situated below the top of a peripheral skirt fragmented externally so as to define crimping lugs. In other words, the cover is provided with a rim with an inverted U-shaped radial profile, the crimping lugs being individualized in the outer annular wall of this rim. A seal is housed in the peripheral space defined by the U-shaped rim. The lugs are designed to be assembled to a rounded rim of the container (generally defined by a roll), by radial discharge towards the inside. This crimping has the effect of applying the seal against the rim of the container to ensure a tight closure.

La résistance mécanique et l'étanchéité globale d'un tel récipient fermé par un couvercle de ce type sont appréciées par un certain nombre de tests pratiqués dans des conditions prédéterminées.The mechanical strength and overall tightness of such a container closed by a cover of this type are assessed by a number of tests carried out under predetermined conditions.

Le test de hauteur de chute consiste à laisser tomber le récipient fermé et rempli de liquide (de l'eau) à 98%, de façon que le bord du couvercle heurte le sol. On détermine ainsi la hauteur dont le récipient peut tomber dans les conditions les plus défavorables, sans aucune perte d'étanchéité.The drop height test consists of dropping the closed container filled with 98% liquid (water) so that the edge of the lid hits the ground. This determines the height from which the container can fall under the most unfavorable conditions, without any loss of tightness.

Le test de pression interne consiste à augmenter progressivement la pression dans un récipient fermé par un tel couvercle jusqu'à ce qu'une fuite soit détectée. On note ainsi la pression maximum atteinte.The internal pressure test consists in gradually increasing the pressure in a container closed by a such cover until a leak is detected. The maximum pressure reached is thus noted.

L'invention propose des modifications de structure qui améliorent notablement les résultats des tests mentionnés ci-dessus, au moins.The invention provides structural modifications which significantly improve the results of the tests mentioned above, at least.

Dans cet esprit, l'invention concerne essentiellement un couvercle métallique pour récipient, notamment pour récipient destiné au transport de matières dangereuses, du type comportant une paroi centrale en contrebas du sommet d'une jupe périphérique fragmentée extérieurement, définissant une pluralité de pattes de sertissage, lesdites pattes étant prévues pour être assemblées à un rebord dudit récipient par refoulement radial vers l'intérieur, caractérisé en ce que ladite paroi centrale est pourvue de bossages emboutis, répartis au voisinage de sa périphérie, chaque bossage approximativement en forme de segment étant orienté sensiblement vers le milieu de ladite paroi centrale.In this spirit, the invention essentially relates to a metal cover for a container, in particular for a container intended for the transport of dangerous materials, of the type comprising a central wall below the top of a peripheral skirt fragmented externally, defining a plurality of crimping lugs , said tabs being designed to be assembled to a rim of said container by radial discharge towards the inside, characterized in that said central wall is provided with stamped bosses, distributed in the vicinity of its periphery, each boss approximately in the shape of a segment being oriented substantially towards the middle of said central wall.

Selon une autre caractéristique avantageuse de l'invention une gorge périphérique est pratiquée dans ladite paroi centrale et cette gorge s'étend entre ladite jupe et lesdits bossages. En outre, ces bossages sont emboutis en creux sur la face interne de la paroi centrale.According to another advantageous characteristic of the invention, a peripheral groove is formed in said central wall and this groove extends between said skirt and said bosses. In addition, these bosses are stamped hollow on the inner face of the central wall.

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 couvercle métallique conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels:

  • - la figure 1 est une vue générale en perspective du couvercle conforme à l'invention; et
  • - la figure 2 est une vue partielle en coupe radiale de ce même couvercle.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a metal cover in accordance with its principle, given only by way of example and made with reference to the drawings annexed in which:
  • - Figure 1 is a general perspective view of the cover according to the invention; and
  • - Figure 2 is a partial view in radial section of the same cover.

Sur les dessins, on a représenté un couvercle métallique 11, ici à contour globalement circulaire, comportant une paroi centrale 12 et une jupe périphérique 13 à profil sensiblement en forme de U renversé, présentant un sommet 14 annulaire, continu et une paroi extérieure 16 fragmentée de façon à définir une pluralité de pattes de sertissage 17. Le couvercle est défini par emboutissage d'un flan de tôle, de façon que ladite partie centrale soit en contrebas du sommet 14 de ladite jupe. Chaque patte se termine classiquement par un roulé extérieur 17a. Un joint 19 en matériau élastomère se trouve logé au voisinage dudit sommet à l'intérieur de l'espace annulaire défini par la jupe. Les pattes sont prévues pour être assemblées par sertissage à un rebord arrondi du récipient (non représenté) généralement matérialisé par un autre roulé. Plus précisément, lorsque le couvercle est en place sur le rebord du récipient, ledit sertissage s'effectue par refoulement desdites pattes, radialement vers l'intérieur, ce qui a pour effet de provoquer la compression du joint contre la surface du rebord du récipient.In the drawings, a metal cover 11 is shown, here with a generally circular outline, comprising a central wall 12 and a peripheral skirt 13 with a profile substantially in the shape of an inverted U, having a continuous annular apex 14 and an fragmented external wall 16 so as to define a plurality of legs crimping 17. The cover is defined by stamping a sheet blank, so that said central part is below the top 14 of said skirt. Each leg conventionally ends with an outside roll 17 a . A seal 19 made of elastomeric material is housed in the vicinity of said apex inside the annular space defined by the skirt. The tabs are intended to be assembled by crimping to a rounded rim of the container (not shown) generally materialized by another roll. More precisely, when the cover is in place on the rim of the container, said crimping is carried out by pushing back said tabs, radially inwards, which has the effect of causing the compression of the seal against the surface of the rim of the container.

Selon une caractéristique importante de l'invention, la paroi centrale 12 est pourvue de bossages 20 réalisés par emboutissage et répartis, de préférence régulièrement, au voisinage de sa périphérie. Chaque bossage 20 en forme approximative de segment est orienté sensiblement vers le milieu de la partie centrale 12, c'est-à-dire ici sensiblement radialement.According to an important characteristic of the invention, the central wall 12 is provided with bosses 20 produced by stamping and distributed, preferably regularly, in the vicinity of its periphery. Each boss 20 in approximate segment shape is oriented substantially towards the middle of the central part 12, that is to say here substantially radially.

Les bossages sont emboutis en creux sur la face interne de la paroi centrale 12. Dans l'exemple représenté, on a pratiqué six bossages décalés de 60°, mais il est parfaitement possible d'envisager un nombre différent de bossages, notamment un plus grand nombre. De plus, une gorge périphérique 22 est pratiquée, également par l'emboutissage, dans la paroi centrale. Cette gorge s'étend entre la jupe et lesdits bossages. Ceux-ci sont d'ailleurs disposés de façon à partir sensiblement du bord interne de la gorge 22. Enfin, il est à noter que cette dernière a un profil en cuvette, à fond plat et présente un pente intérieure 23a plus faible que la pente extérieure 23b.The bosses are stamped hollow on the internal face of the central wall 12. In the example shown, six bosses offset by 60 ° were made, but it is perfectly possible to envisage a different number of bosses, in particular a larger one number. In addition, a peripheral groove 22 is formed, also by stamping, in the central wall. This groove extends between the skirt and said bosses. These are moreover arranged so as to start substantially from the internal edge of the groove 22. Finally, it should be noted that the latter has a bowl-shaped profile, with a flat bottom and has an internal slope 23 which is lower than the external slope 23 b .

La structure décrite ci-dessus permet une amélioration du test de hauteur de chute de 40cm pour un récipient de 30cm de diamètre, soit pratiquement le double de ce qu'il était possible d'obtenir antérieurement. On peut sans doute attribuer ce résultat au fait que les empreintes se situant en dehors de l'impact de chute localisé sur le bord, les déformations du couvercle s'effectuent plus particulièrement vers l'extérieur et absorbent donc l'énergie de façon plus favorable, sans rupture d'étanchéité de l'assemblage couvercle-récipient.The structure described above allows an improvement of the drop height test of 40cm for a container 30cm in diameter, almost double what it was possible to obtain previously. We can probably attribute this result to the fact that the imprints being located outside the fall impact located on the edge, the deformations of the cover take place more particularly towards the outside and therefore absorb energy more favorably, without breaking d sealing of the lid-container assembly.

Le gain au test de pression interne est d'environ 200 millibars. On pense que la présence des empreintes, notamment, permet de mieux répartir la déformation résultant de la pression interne. On évite ainsi la formation localisée d'un becquet ou d'une pliure analogue qui serait susceptible d'amorcer une fuite.The gain on the internal pressure test is around 200 millibars. It is believed that the presence of the imprints, in particular, makes it possible to better distribute the deformation resulting from the internal pressure. This avoids the localized formation of a spoiler or a similar fold which could cause a leak.
