Description

La présente invention est relative à des prefectionnements apportés aux boîtes alvéoléés du genre de celles qu'on utilise pour emballer des oeufs ou des objets fragiles divers.The present invention relates to prefectionnements brought to the honeycombed boxes of the kind that are used to package eggs or various fragile objects.

Elle concerne plus particulièrement, quoi­que non exclusivement, une boîte à oeufs constituée par deux éléments assemblés, à savoir:
-un casier alvéolé réalisé d'une pièce en matière plastique thermoformée;
-un couvercle, constitué par une simple pla­que découpée dans une feuille de carton ou analogue.It relates more particularly, although not exclusively, to an egg box constituted by two assembled elements, namely:
-a honeycomb locker made of a piece of thermoformed plastic;
-a cover, consisting of a simple plate cut from a sheet of cardboard or the like.

Des moyens sont prévus pour fixer le couver­cle sur le casier, après mise en place des oeufs dans les alvéoles. Ces moyens sont généralement constitués sur les boîtes à oeufs connues, par un système d'encliquetage à force du couvercle sur des profils convenablement définis en contre-dépouille sur la partie supérieure du casier.Means are provided for fixing the cover to the rack, after placing the eggs in the cells. These means are generally constituted on known egg cartons, by a system of snap-fastening of the cover on profiles suitably defined as an undercut on the upper part of the rack.

Un tel système connu présente divers incon­vénients. En particulier la fermeture de la boite n'est pas inviolable et elle n'interdit pas certaines tricheries dans les magasins en self-service: il reste possible d'ouvrir le couvercle pour voler une partie du contenu, ou pour remplacer un oeuf cassé, après quoi le couvercle est refermé.Such a known system has various drawbacks. In particular, closing the box is not inviolable and it does not prohibit certain cheating in self-service stores: it is still possible to open the lid to steal part of the contents, or to replace a broken egg, after which the cover is closed.

De plus, l'efficacité du clipsage est souvent insuffisante pour empêcher le couvercle de se déverrouiller sous le seul poids des oeufs si la boîte vient à être retour­née.In addition, the effectiveness of clipping is often insufficient to prevent the lid from unlocking under the weight of the eggs only if the box is to be turned over.

Enfin un tel système ne permet pas la mise en place à coups sur du couvercle sur le casier dans une chaîne d'emballage à fonctionnement entièrement automatique.Finally, such a system does not allow the blows to be placed on the cover on the rack in a fully automatic packaging chain.

Dans certains cas, on est obligé de prévoir dans la plaque du couvercle, le découpage d'ouverture d'en­cliquetage qui compromettent l'aspect esthétique de la boîte et diminuent d'autant la surface restée disponible pour im­primer éventuellement le couvercle. Ce dernier étant généra­lement constitué par une cartonnette découpée, il est opaque et masqué à la vue de l'acheteur, les oeufs ainsi emballés.In some cases, it is necessary to provide in the cover plate, the ratchet opening cutout which compromises the aesthetic appearance of the box and correspondingly reduces the area remaining available for possibly printing the cover. The latter generally being made up of a cut cardboard, it is opaque and hidden from the view of the buyer, the eggs thus packaged.

La présente invention a pour but d'éviter ces inconvénients en réalisant une boîte à oeufs fermée de façon invoilable, par une mise en oeuvre effectuée sur une chaîne d'emballage à fonctionnement entièrement automatique.The object of the present invention is to avoid these drawbacks by producing a closed egg box of invoicable way, by an implementation carried out on a fully automatic packaging line.

Une boîte à oeufs selon l'invention com­prend un couvercle découpé plat, qu'on rapporte sur la par­tie supérieure d'un casier alvéolé en matière plastique thermoformée pour définir, entre les alvéoles, des colonnes dirigées vers le haut alors qu'un bord périphérique entoure la partie supérieure du casier, des moyens étant par ail­leurs prévus pour fixer le couvercle sur le casier après remplissage,et elle est caractérisée en ce que ces moyens sont constitués par la combinaison des éléments suivants:

  • a)plusieurs colonnes entre les alvéoles ont un sommet plat situé sensiblement au même niveau que le bord périphérique du casier.
  • b)au moment de sa mise en place sur le casier plein, le couvercle est collé sur des parties du ca­sier situées dans le plan commun aux sommets des colonnes et au bord périphérique.
An egg carton according to the invention comprises a flat cut lid, which is attached to the upper part of a honeycomb plastic thermoformed rack to define, between the honeycombs, columns directed upwards while a peripheral edge surrounds the upper part of the crate, means being also provided for fixing the cover to the crate after filling, and it is characterized in that these means are constituted by the combination of the following elements:
  • a) several columns between the cells have a flat top located substantially at the same level as the peripheral edge of the rack.
  • b) at the time of its installation on the full rack, the cover is glued to parts of the rack located in the plane common to the tops of the columns and to the peripheral edge.

Suivant une autre caractéristique de l'in­vention, le collage est effectué par apposition d'un point de colle ou d'un cordon de colle sur les zones à assembler.According to another characteristic of the invention, the bonding is carried out by affixing a point of glue or a bead of glue on the areas to be assembled.

Suivant une autre caractéristique de l'in­vention, le collage est effectué à chaud par injection de colle selon la technique connue sous le nom de "hot-melt".According to another characteristic of the invention, the bonding is carried out hot by injection of glue according to the technique known under the name of "hot-melt".

Le dessin annexé, donné à titre d'exemple non limitatif, permettra de mieux comprendre l'invention et les avantages qu'elle est susceptible de procurer.

  • Figure 1 montre le casier d'une boîte à oeufs selon l'invention, lorsqu'on y pose des points de colle avant la mise en place du couvercle.
  • Figure 2 est une coupe suivant II-II(Fig. 1).
  • Figure 3 montre le couvercle lorsqu'on le présente sur le casier pour refermer la boîte.
The appended drawing, given by way of nonlimiting example, will allow a better understanding of the invention and the advantages which it is likely to provide.
  • Figure 1 shows the rack of an egg carton according to the invention, when glue dots are placed there before the cover is put in place.
  • Figure 2 is a section along II-II (Fig. 1).
  • Figure 3 shows the cover when presented on the rack to close the box.

La boîte à oeufs représentée sur les des­sins comporte un casier 1 réalisé par exemple à partir d'­une feuille de matière plastique thermoformée. Il comporte des alvéoles 2 séparés par des colonnes 3 dont le sommet 4 est plat.The egg carton shown in the drawings includes a rack 1 made for example from a sheet of thermoformed plastic. It has cells 2 separated by columns 3 whose top 4 is flat.

Chaque alvéole 2 est destinée à recevoir un objet tel qu'un oeuf 5.Each cell 2 is intended to receive an object such as an egg 5.

La partie supérieure du casier 1 est en­tourée par un bord plat 6 qui peut à son tour être renfor­cé par un rebord de raidissement 7. Le sommet plat 4 des colonnes 3 est situé dans le même plan géométrique 8 que la face supérieure du bord plat 6.The upper part of the rack 1 is surrounded by a flat edge 6 which can in turn be reinforced by a stiffening rim 7. The flat top 4 of the columns 3 is located in the same geometrical plane 8 as the upper face of the flat edge 6 .

La boite à oeufs comporte par ailleurs un couvercle 9 entièrement plat et entièrement plein, c'est-­à-dire dans l'intérieur duquel aucune ouverture n'est dé­coupée. Par contre une encoche latérale 10 peut être pré­vue sur son contour périphérique.The egg box also has a completely flat and completely full cover 9, that is to say in the interior of which no opening is cut. On the other hand, a lateral notch 10 can be provided on its peripheral contour.

Le couvercle 9 est découpé dans une feuille d'un matériau quelconque qui peut être notamment:
-une plaque de matière plastique transpa­rente;
-une matière plastique opaque,
-voire même une simple cartonnette.The cover 9 is cut from a sheet of any material which may in particular be:
-a transparent plastic plate;
- an opaque plastic material,
- even a simple cardboard.

En particulier, le couvercle 9 peut être en une matière particulièrement bon marché.In particular, the cover 9 can be of a particularly inexpensive material.

Le fonctionnement est le suivant:The operation is as follows:

Après avoir placé les oeufs 5 dans les alvéoles 2 du casier 1, on appose un point de colle 11 sur le sommet plat 4 des colonnes 3. Il suffit alors de poser le couvercle 9 sur le plan d'appui 8 du casier 1, pour que la fermeture de la boîte se trouve assurée de façon invio­lable.After placing the eggs 5 in the cells 2 of the rack 1, a point of glue 11 is affixed to the flat top 4 of the columns 3. It then suffices to place the cover 9 on the support surface 8 of the rack 1, to that the box is closed inviolably.

En variante, on peut remplacer le point de colle 11 sur le sommet 4 des colonnes 3, par un cordon de colle apposée sur le bord périphérique 6: dans ce cas, le couvercle 9 est collé par sa périphérie sur le casier 1. Ce collage peut être effectué par points ou en continu.Alternatively, the point of glue 11 on the top 4 of the columns 3 can be replaced by a bead of glue affixed to the peripheral edge 6: in this case, the cover 9 is glued by its periphery to the crate 1. This gluing can be done by points or continuously.

Dans tous les cas, la colle peut être ap­pliquée par un injecteur 12 ou au moyen d'un pinceau. L'application peut s'effectuer à froid, ou par la techni­que connue, dite du "hot melt".In all cases, the adhesive can be applied by an injector 12 or by means of a brush. The application can be carried out cold, or by the known technique, known as "hot melt".

On voit que le casier 1 ne comporte ain­si aucune en contre-dépouille dans la zone des colonnes 3, ce qui permet d'utiliser une matière plastique bon marché et d'automatiser entièrement les chaînes d'emballage.It can be seen that the rack 1 thus has no undercut in the area of the columns 3, which makes it possible to use an inexpensive plastic and fully automate the packaging lines.

Bien entendu, hors des colonnes 3, le casier 1 peut présenter (notamment sur sa périphérie), des zones en contre-dépouille de type connu du genre de celles qu'on pré­voit, par exemple pour faciliter le désempilage de plusieurs casiers superposés.Of course, outside of the columns 3, the rack 1 may have (in particular on its periphery), undercut areas of known type of the type provided for, for example to facilitate the unstacking of several stacked racks.
