Description

La présente invention a pour objet un dispositif de fixation d'un couvercle sur une boîte en matière plastique, utilisable notamment pour les emballages destinés à la présentation et à la vente d'articles de moyennes et petites dimensions, en particulier d'articles de quincaillerie vendus à l'unité ou en lots, ledit emballage pouvant servir au rangement ultérieur de tels articles.The subject of the present invention is a device for fixing a cover to a plastic box, usable in particular for packaging intended for the presentation and sale of medium and small dimensions articles, in particular hardware items. sold individually or in batches, said packaging can be used for the subsequent storage of such items.

Des emballages de ce type doivent comporter un dispositif de fermeture réutilisable, qui soit inviolable lors de leur exposition à la vente, ou permette du moins de constater que l'emballage a été violé.Packaging of this type must include a reusable closure device, which is tamper-proof when exposed to sale, or at least allows the packaging to be found to have been breached.

Il existe des emballages présentant ces caractéristiques, notamment celui décrit dans la demande de brevet français 91/03557 au nom de la Demanderesse, et qui comporte d'une part un dispositif de fermeture par emboîtage du couvercle sur la boîte, et d'autre part un dispositif d'inviolabilité constitué de picots, de type harpon, solidaires dudit couvercle, qui sont introduits à la fermeture dans des orifices pratiqués dans les bords de la boîte, et qu'il est nécessaire de sectionner pour enlever le couvercle lors de la première utilisation.There are packages having these characteristics, in particular that described in French patent application 91/03557 in the name of the Applicant, and which comprises on the one hand a closure device by fitting the lid onto the box, and on the other hand a tamper-evident device made up of spikes, of the harpoon type, integral with said cover, which are introduced when closed in orifices practiced in the edges of the box, and that it is necessary to cut to remove the cover during the first use.

Ce dispositif présente toutefois l'inconvénient, lors de la réutilisation de l'emballage, d'une fermeture peu solide, susceptible de lâcher par exemple lors d'une chute de l'emballage.However, this device has the drawback, when the packaging is reused, of a weak closure, liable to drop, for example when the packaging falls.

La présente invention vise à remédier à cet inconvénient en proposant un dispositif de fixation d'un couvercle sur une boîte en matière plastique, destiné notamment aux emballages réutilisables, et présentant, outre les caractéristiques des emballages existants qui viennent d'être évoquées, l'avantage d'une solidarisation robuste du couvercle sur la boîte lors de sa réutilisation.The present invention aims to remedy this drawback by proposing a device for fixing a cover to a plastic box, intended in particular for reusable packaging, and having, in addition to the characteristics of the existing packaging which has just been mentioned, the advantage of a robust attachment of the cover to the box when it is reused.

A cet effet, le dispositif selon l'invention comporte, sur les bords du couvercle, saillant de sa face interne, des ergots s'encliquetant dans un des orifices pratiqués en bordure du contenant.To this end, the device according to the invention comprises, on the edges of the cover, projecting from its internal face, lugs snapping into one of the orifices made at the edge of the container.

Conformément à l'invention, chaque ergot est sensiblement en forme de V, solidarisé à la face interne du couvercle par l'extrémité d'une de ses branches, pointe du V dirigée vers le bas, l'autre branche étant libre.According to the invention, each lug is substantially V-shaped, secured to the internal face of the cover by the end of one of its branches, point of the V directed downwards, the other branch being free.

Toujours conformément à l'invention, l'orifice pratiqué dans le bord du contenant pour accueillir un ergot est de forme rectangulaire et n'est pas disposé exactement en regard dudit ergot, de manière que, lors de l'introduction de celui-ci, ladite introduction ne puisse s'effectuer que grâce à l'élasticité de la branche libre dudit ergot, dont l'extrémité, après introduction, se trouve disposée contre la face inférieure du bord du contenant, bloquant ainsi le couvercle en position de fermeture.Still in accordance with the invention, the orifice made in the edge of the container to receive a lug is rectangular in shape and is not placed exactly opposite said lug, so that, when it is introduced, said introduction can only be carried out thanks to the elasticity of the free branch of said lug, the end of which, after introduction, is disposed against the underside of the edge of the container, thus blocking the cover in the closed position.

L'ouverture du couvercle peut s'effectuer en exerçant une traction jusqu'à ce que la branche libre de l'ergot s'efface.The lid can be opened by pulling until the free leg of the lug disappears.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and features of the present invention will become more apparent from the description which follows and which relates to the appended drawing, which represents a nonlimiting embodiment thereof.

Dans le dessin annexé :

  • la figure 1 représente une vue en perspective d'un emballage dont le couvercle est clos au moyen d'un dispositif de fermeture selon l'invention.
  • la figure 2 représente une vue partielle en perspective, avec arraché partiel, de l'emballage de la figure 1 lorsqu'il est ouvert.
  • la figure 3a représente une vue en coupe verticale et longitudinale du dispositif de fermeture selon l'invention, avant solidarisation du couvercle au contenant.
       la figure 3b représente une vue en coupe verticale et longitudinale du même dispositif après solidarisation du couvercle au contenant.
In the attached drawing:
  • Figure 1 shows a perspective view of a package whose lid is closed by means of a closure device according to the invention.
  • 2 shows a partial perspective view, partially broken away, of the packaging of Figure 1 when open.
  • Figure 3a shows a vertical and longitudinal sectional view of the closure device according to the invention, before the lid is secured to the container.
    Figure 3b shows a vertical and longitudinal sectional view of the same device after securing the cover to the container.

Si on se réfère à la figure 1 on peut voir qu'un emballage 1 selon l'invention est constitué d'un contenant 2 sur lequel est ajusté un couvercle 3.If we refer to FIG. 1, we can see that a package 1 according to the invention consists of a container 2 on which a cover 3 is fitted.

Le contenant 2 tel que représenté comporte, bordant son ouverture, un rebord 20 plat sur lequel s'encastre le rebord en creux 30 d'un couvercle 3.The container 2 as shown has, bordering its opening, a flat rim 20 on which the hollow rim 30 of a cover 3 is fitted.

Ce couvercle 3 comporte des lignes de pliage 31 permettant des ouvertures partielles de l'emballage 1. Non loin de chacune de ces lignes de pliage 31 et aux extrémités, le couvercle 3 est solidarisé au contenant 2 au moyen du dispositif de fermeture 4 selon l'invention.This cover 3 comprises fold lines 31 allowing partial openings of the packaging 1. Not far from each of these fold lines 31 and at the ends, the cover 3 is secured to the container 2 by means of the closure device 4 along the 'invention.

Si on se réfère maintenant à la figure 2 on peut voir qu'un dispositif de fermeture 4 comporte d'une part un ergot 5 solidaire du rebord 30 du couvercle 3 à sa face inférieure et d'autre part un orifice 6 pratiqué dans le rebord 20 du contenant 2.Referring now to Figure 2 we can see that a closure device 4 comprises on the one hand a lug 5 secured to the flange 30 of the cover 3 on its underside and on the other hand an orifice 6 formed in the flange 20 of container 2.

L'ergot 5 est sensiblement en forme de V dont l'extrémité d'une branche 50 est solidarisée à la face inférieure du rebord 30, l'extrémité de l'autre branche 51 étant libre.The lug 5 is substantially V-shaped, the end of a branch 50 is secured to the underside of the flange 30, the end of the other branch 51 being free.

Si on se réfère également aux figures 3a et 3b on peut voir que les dimensions et la position de l'orifice 6 sont telles que l'introduction de l'ergot 5 n'est réalisable que grâce à l'élasticité de la branche 51 qui peut se replier sur la branche 50.If we also refer to Figures 3a and 3b we can see that the dimensions and the position of the orifice 6 are such that the introduction of the lug 5 is only achievable thanks to the elasticity of the branch 51 which can be folded back on branch 50.

Ainsi, lors de l'introduction de l'ergot 5 dans l'orifice 6, la branche 51 se replie sur la branche 50 puis, une fois le rebord 20 dépassé, reprend sa forme initiale, son extrémité supérieure 52 venant prendre appui contre la face inférieure dudit rebord 20, bloquant le couvercle 3 en position de fermeture. L'ouverture de l'emballage 1 ne peut ensuite se faire qu'en exerçant une traction importante sur le couvercle 3, traction qui a pour effet d'écarter la branche 51 de la branche 50 et de permettre son passage par l'orifice 6.Thus, during the introduction of the lug 5 into the orifice 6, the branch 51 folds back on the branch 50 then, once the rim 20 has passed, resumes its initial shape, its upper end 52 coming to bear against the underside of said flange 20, locking the cover 3 in the closed position. The opening of the packaging 1 can then only be done by exerting a significant traction on the cover 3, traction which has the effect of separating the branch 51 from the branch 50 and allowing its passage through the orifice 6 .

Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.

Ainsi, afin de garantir l'inviolabilité de l'emballage lors de sa présentation à la vente, ledit emballage pourra être muni subsidiairement de picots solidaires de la face supérieure du rebord du contenant, destinés à être introduits dans des orifices pratiqués dans le rebord du couvercle et écrasés thermiquement, et qu'il y aura lieu de couper pour pouvoir ouvrir l'emballage.Thus, in order to guarantee the inviolability of the packaging during its presentation for sale, said packaging may be provided in the alternative with pins integral with the upper face of the rim of the container, intended to be introduced into orifices made in the rim of the cover and thermally crushed, and it will be necessary to cut to be able to open the packaging.
