Abstract

The invention relates to a lid made of moulded synthetic material, intended to be fitted in a fluid-tight manner onto a container 1 provided with an external attachment rim. The lid 10 is arranged to be particularly rigid in its peripheral zone. The lid is in the form of a plate whose periphery has a sinuous transverse profile, forming a fitting channel 16 open in the downward direction and intended to fit onto the edge of the container 1, and a channel 14 open in the upward direction and provided with transverse stiffening ribs 22. Preferably, this channel is bordered by an upper relief 12 for the centring of another container placed on the lid. The external wall 19 of the fitting channel has several attachment protrusions 20 distributed on the periphery and cooperating with an attachment rim 3 of the container. The position of each attachment protrusion 20 is marked on the upper surface of the lid by a mark in relief 25 symbolising a thumbprint. The fitting channel 16 comprises a groove 18 which houses a sealing tongue 6 provided on the edge of the container. Such a lid can be used on a container made of synthetic material for food products, paints or other liquid, pasty or solid products.

Description

CmVERCLE EN MATIERE SYNTHETIQUE A EMBOITER SUR UN REg1PENT.- La présente invention concerne un couvercle en matière synthétique moulée, destiné à être emboîté de manière étanche sur une ouverture supérieure d'un récipient en matière synthétique pourvue d'un rebord d'accrochage qui est protubérant vers l'extérieur autour de cette ouverture, le couvercle ayant sensiblement la forme d'une plaque dont le p- aur tour est replié suivant un bord profilé dont la face inférieure présente une gorge d'emboîtement agencée pour coopérer avec ledit -repórd d'accrochage. The present invention relates to a cover of molded synthetic material, intended to be fitted in a leaktight manner onto an upper opening of a container of synthetic material provided with a hooking rim which is protruding outward around this opening, the cover having substantially the shape of a plate whose p- aur tower is folded along a profiled edge whose lower face has an interlocking groove arranged to cooperate with said -repórd d 'hanging.

Les couvercles de ce genre sont bien connus et permettent une fermeture
étanche de différentes sortes de récipients qu'on doit ouvrir et refermer
de temps en temps et dans lesquels on conserve par exemple des produits
al;rnentaires, des peintures, des colles ou d'autres produits liquides,
piteux ou solides. La tenue et l'étanchéité d'un tel couvercle sur le
récipient sont assurées par la forme particulière de son bord coopérant
avec le bord de l'ouverture du récipient, c'est-à-dire que la rigidité du
couvercle dans cette zone joue un rôle primordial.De plus, comme les
récipients fermés sont souvent empilés les uns sur les autres et stockés
par gerbage, leur couvercle a tendance à se déformer sous le poids des
récipients qu'ils supportent, ce qui peut déformer son bord et nuire à une
r,e étanchéité. C'est pourquoi on est souvent amené à renforcer le
bord du couvercle en l'épaississant, ce qui a pour inconvénient une
conSommation accrue de matière, ainsi qu'une raideur longitudinale
excessive du bord du couvercle, qu'on a alors de la peine à déformer
manuellement pour l'emboîter ou pour l'ôter du récipient.Lids of this kind are well known and allow closure
waterproof of different kinds of containers that must be opened and closed
from time to time and in which products are kept, for example
supplies, paints, glues or other liquid products,
pitiful or solid. The holding and sealing of such a cover on the
container are ensured by the particular shape of its cooperating edge
with the edge of the container opening, i.e. the rigidity of the
cover in this area plays a vital role.
closed containers are often stacked on top of each other and stored
by stacking, their cover tends to deform under the weight of
containers that they support, which can distort its edge and harm a
r, e sealing. This is why we are often led to strengthen the
edge of the cover by thickening it, which has the disadvantage of
increased material consumption, as well as longitudinal stiffness
excess of the edge of the cover, which is then difficult to deform
manually to nest it or to remove it from the container.

Par. consequent, la présente invention a pour but d'agencer un tel couvercle de façon à raidir son bord tout en minimisant la consommation
deKmatière et en facilitant les manoeuvres de mise en place et
d'enlèvement du couvercle. By. Therefore, the present invention aims to arrange such a cover so as to stiffen its edge while minimizing consumption
deKmatière and by facilitating the maneuvers of installation and
cover removal.

Dans ce but, l'invention fournit un couvercle du type indiqué en préambule, caractérisé en ce qu'il comporte une zone centrale séparée de la gorge d'emboîtement par un profil raidisseur comportant une gorge ouverte vers le haut et pourvue de nervures transversales de raidissement.To this end, the invention provides a cover of the type indicated in the preamble, characterized in that it comprises a central zone separated from the nesting groove by a stiffening profile comprising a groove open upwards and provided with transverse ribs. stiffening.

Le couvercle peut comporter avantageusement, entre la zone centrale et le profil raidisseur, un relief supérieur constituant un moyen de centrage d'un récipient posé sur le couvercle.The cover may advantageously include, between the central zone and the stiffening profile, an upper relief constituting a means for centering a container placed on the cover.

Dans une forme de réalisation préférée du couvercle selon l'invention, la gorge d'emboîtement comporte une série de bourrelets d'accrochage qui sont espacés les uns des autres et répartis le long de la gorge en regard du rebord d'accrochage du récipient pour s y accrocher grâce à l'élasticité du couvercle. Dans ce cas, le couvercle peut comporter sur sa face supérieure, à proximité du profil raidisseur, une série d'empreintes qui sont disposées en regard des positions respectives desdits bourrelets d'accrochage. De préférence, chacune de ces empreintes a une forme en cuvette pour l'appui d'un pouce d'un utilisateur emboîtant le couvercle sur le récipient.In a preferred embodiment of the cover according to the invention, the nesting groove comprises a series of hooking beads which are spaced from one another and distributed along the groove opposite the hooking rim of the container for hang on thanks to the elasticity of the cover. In this case, the cover may comprise on its upper face, near the stiffening profile, a series of indentations which are arranged opposite the respective positions of said attachment beads. Preferably, each of these imprints has a bowl shape for the support of an inch of a user fitting the lid onto the container.

Dans une forme de réalisation avantageuse, le couvercle comporte, au fond de la gorge d'emboîtement, une rainure continue agencée pour recevoir une languette d'étanchéité s'étendant vers le haut sur le pourtour de l'ouverture du récipient.In an advantageous embodiment, the cover comprises, at the bottom of the interlocking groove, a continuous groove arranged to receive a sealing tongue extending upwards around the periphery of the opening of the container.

Dans une forme de réalisation particulière adaptée à un récipient circulaire, le couvercle et ladite gorge ouverte vers le haut sont circulaires et lesdites nervures de raidissement sont disposées radialement.In a particular embodiment adapted to a circular container, the lid and said groove open upwards are circular and said stiffening ribs are arranged radially.

La présente invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation, en référence aux dessins annexés, dans lesquels
La figure 1 représente en perspective un exemple d'un couvercle selon l'invention, placé sur un seau en matière synthétique, et la figure 2 est une vue partielle en coupe verticale suivant la ligne ll-ll de la figure 1.The present invention will be better understood with the aid of the following description of an exemplary embodiment, with reference to the appended drawings, in which
FIG. 1 shows in perspective an example of a lid according to the invention, placed on a plastic bucket, and FIG. 2 is a partial view in vertical section along the line ll-ll of FIG. 1.

En référence aux figures, un seau de type connu I en matière synthétique moulée, pourvu d'une anse 2, comporte autour de son ouverture supérieure un rebord extérieur d'accrochage 3 qui est dirigé obliquement vers le bas et qui est relié à la paroi latérale tronconique 4 du seau par une série de nervures radiales 5 augmentant sa rigidité. En outre, le bord supérieur du seau I est muni d'une languette continue d'étanchéité 6 dirigée vers le haut.With reference to the figures, a bucket of known type I in molded synthetic material, provided with a handle 2, comprises around its upper opening an external hooking rim 3 which is directed obliquely downwards and which is connected to the wall frustoconical lateral 4 of the bucket by a series of radial ribs 5 increasing its rigidity. In addition, the upper edge of the bucket I is provided with a continuous sealing tongue 6 directed upwards.

Le seau I est obturé de manière étanche au moyen d'un couvercle circulaire 10 en matière synthétique moulée, dont le profil transversal comprend, du centre vers l'extérieur, une zone centrale 11 sensiblement plate, un bourrelet supérieur 12 destiné à faciliter le gerbage, afin de centrer le fond d'un autre seau I posé sur lui, un repli inférieur 13 formant une gorge 14 ouverte vers le haut, et un repli supérieur 15 formant une gorge d'emboîtement 16 destinée à chevaucher le bord du seau I et à maintenir le couvercle de manière étanche sur lui. Pour garantir l'étanchéité, il est prévu au fond de la gorge 16 une petite rainure 18 légèrement évasée, dans laquelle se coince la languette d'étanchéité 6 quand on emboîte le couvercle sur le seau.Du côté extérieur, la gorge 16 est délimitée par une paroi oblique 19 qui peut être relativement mince, donc flexible, et qui comporte sur sa face intérieure six bourrelets d'accrochage 20 uniformément répartis sur le pourtour du couvercle et agencés pour s'accrocher contre le rebord 3 du récipient. Quand on veut enlever le couvercle, on décroche facilement les bourrelets 20 en tirant vers l'extérieur le bord inférieur de la paroi 19. The bucket I is sealed in a sealed manner by means of a circular cover 10 of molded synthetic material, the transverse profile of which comprises, from the center towards the outside, a central zone 11 which is substantially flat, an upper bead 12 intended to facilitate stacking. , in order to center the bottom of another bucket I placed on it, a lower fold 13 forming a groove 14 open upwards, and an upper fold 15 forming a nesting groove 16 intended to overlap the edge of the bucket I and to hold the cover tightly on it. To guarantee sealing, a small slightly flared groove 18 is provided at the bottom of the groove 16, in which the sealing tongue 6 gets caught when the cover is fitted on the bucket. On the outside, the groove 16 is delimited by an oblique wall 19 which can be relatively thin, therefore flexible, and which comprises on its inner face six hooking beads 20 uniformly distributed around the periphery of the cover and arranged to hang against the rim 3 of the container. When the cover is to be removed, the beads 20 are easily removed by pulling the lower edge of the wall 19 outwards.

Comme le montre la figure 2, le couvercle a la forme d'une plaque galbée dont l'épaisseur est relativement faible et, dans le cas présent, plus ou moins constante. Afin de lui conférer une rigidité suffisante dans sa région périphérique, il est prévu une série de nervures radiales 22 s'étendant sur toute la profondeur de la gorge 14 et régulièrement espacées le long de cette gorge. En combinaison avec le repli inférieur 13 qui définit la gorge, les nervures 22 créent une zone particulièrement rigide qui prend appui contre la paroi latérale relativement rigide 4 du seau et qui créent donc un effet d'encastrement empêchant une torsion du bord du couvercle emboîté sur le seau, sans nécessiter aucune surépaisseur localisée dans le couvercle.La rigidité ainsi obtenue est spécialement avantageuse dans les cas où le couvercle 10 doit supporter le poids d'un objet posé sur lui, en particulier de plusieurs seaux empilés.As shown in Figure 2, the cover has the shape of a curved plate whose thickness is relatively small and, in this case, more or less constant. In order to give it sufficient rigidity in its peripheral region, a series of radial ribs 22 is provided extending over the entire depth of the groove 14 and regularly spaced along this groove. In combination with the lower fold 13 which defines the groove, the ribs 22 create a particularly rigid zone which bears against the relatively rigid side wall 4 of the bucket and which therefore create an embedding effect preventing twisting of the edge of the cover fitted onto the bucket, without requiring any localized excess thickness in the cover. The rigidity thus obtained is especially advantageous in cases where the cover 10 has to support the weight of an object placed on it, in particular of several stacked buckets.

D'une part elle empêche qu'une torsion du pli supérieur 15 entraîne un décrochement des bourrelets 20, et d'autre part elle empêche un enfoncement de la zone du bourrelet supérieur 12 du couvercle, c'est-à-dire la zone recevant la charge. Le cas échéant, cette zone peut encore être renforcée par des nervures radiales 23 prévues sur la face inférieure du couvercle en regard de chaque nervure 22 et dessinées en trait interrompu sur la figure 2.On the one hand it prevents a twisting of the upper fold 15 leading to a detachment of the beads 20, and on the other hand it prevents a depression of the area of the upper bead 12 of the cover, that is to say the area receiving load. If necessary, this zone can be further reinforced by radial ribs 23 provided on the underside of the cover opposite each rib 22 and drawn in broken lines in FIG. 2.

Le couvercle représenté comporte également, sur sa face supérieure, six empreintes 24 situées chacune sur un rayon allant du centre du couvercle à l'un des bourrelets 20, près du bourrelet supérieur circulaire i 2. Chaque empreinte 24 est délimitée par une légère saillie en arc de cercle 25 qui entoure, avec le bourrelet 12, une cuvette 26 formant une zone d'appui pour un pouce de l'utilisateur. Ces empreintes ont pour fonction de marquer l'emplacement des bourrelets d'accrochage 20, si bien que l'utilisateur voit directement à quel endroit il faut presser pour accrocher le couvercle de la manière la plus efficace, et surtout à quel endroit il convient de soulever le bord de la paroi extérieure 19 du couvercle pour le décrocher du seau. Au moins une nervure 22 se trouve en face de chaque empreinte 24, ce qui permet de presser fortement sur le couvercle dans cette zone sans le déformer.The cover shown also has, on its upper face, six imprints 24 each located on a radius going from the center of the cover to one of the beads 20, near the circular upper bead i 2. Each imprint 24 is delimited by a slight projection arc 25 which surrounds, with the bead 12, a bowl 26 forming a support zone for an inch of the user. These fingerprints have the function of marking the location of the hanging beads 20, so that the user can see directly where it is necessary to press to hang the cover in the most effective way, and especially where it is advisable to lift the edge of the outer wall 19 of the cover to unhook it from the bucket. At least one rib 22 is located in front of each cavity 24, which makes it possible to press strongly on the cover in this zone without deforming it.

La présente invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus, mais elle s'étend à toute modification ou variante évidente pour un homme du métier. The present invention is not limited to the embodiment described above, but it extends to any modification or variant obvious to a person skilled in the art.
